The Food and Drug Administration has approved dexmedetomidine (Igalmi, BioXcel Therapeutics) sublingual film for the acute treatment of agitation associated with schizophrenia or bipolar I or II disorder in adults.

This is the first FDA-approved, orally dissolving, self-administered sublingual treatment for this indication. With a demonstrated onset of action as early as 20 minutes, it shows a high response rate in patients at both 120-mcg and 180-mcg doses.

An estimated 7.3 million individuals in the United States are diagnosed with schizophrenia or bipolar disorders, and up to one-quarter of them experience episodes of agitation that can occur 10-17 times annually. These episodes represent a significant burden for patients, caregivers, and the health care system.

“There are large numbers of patients who experience agitation associated with schizophrenia and bipolar disorders, and this condition has been a long-standing challenge for health care professionals to treat,” said John Krystal, MD, the Robert L. McNeil Jr. Professor of Translational Research and chair of the department of psychiatry at Yale University, New Haven, Conn.

“The approval of Igalmi, a self-administered film with a desirable onset of action, represents a milestone moment. It provides health care teams with an innovative tool to help control agitation. As clinicians, we welcome this much-needed new oral treatment option,” he added.

“Igalmi is the first new acute treatment for schizophrenia or bipolar disorder–associated agitation in nearly a decade and represents a differentiated approach to helping patients manage this difficult and debilitating symptom,” said Vimal Mehta, PhD, CEO of BioXcel Therapeutics.

The FDA approval of Igalmi is based on data from two pivotal randomized, double-blinded, placebo-controlled, parallel-group, phase 3 trials that evaluated Igalmi for the acute treatment of agitation associated with schizophrenia (SERENITY I) or bipolar I or II disorder (SERENITY II).

The most common adverse reactions (incidence ≥5% and at least twice the rate of placebo) were somnolence, paresthesia or oral hypoesthesia, dizziness, dry mouth, hypotension, and orthostatic hypotension. All adverse drug reactions were mild to moderate in severity. While Igalmi was not associated with any treatment-related serious adverse effects in phase 3 studies, it may cause notable side effects, including hypotension, orthostatic hypotension, bradycardia, QT interval prolongation, and somnolence.

As previously reported by this news organization, data from the phase 3 SERENITY II trial that evaluated Igalmi in bipolar disorders were published in JAMA.

Physically fit children have a greater ability to concentrate and better health-related quality of life (HRQOL), according to a new study.

The findings of the German study involving more than 6,500 kids emphasize the importance of cardiorespiratory health in childhood, and support physical fitness initiatives in schools, according to lead author Katharina Köble, MSc, of the Technical University of Munich (Germany), and colleagues.

“Recent studies show that only a few children meet the recommendations of physical activity,” the investigators wrote in Journal of Clinical Medicine.

While the health benefits of physical activity are clearly documented, Ms. Köble and colleagues noted that typical measures of activity, such as accelerometers or self-reported questionnaires, are suboptimal research tools.

“Physical fitness is a more objective parameter to quantify when evaluating health promotion,” the investigators wrote. “Furthermore, cardiorespiratory fitness as part of physical fitness is more strongly related to risk factors of cardiovascular disease than physical activity.”

According to the investigators, physical fitness has also been linked with better concentration and HRQOL, but never in the same population of children.

The new study aimed to address this knowledge gap by assessing 6,533 healthy children aged 6-10 years, approximately half boys and half girls. Associations between physical fitness, concentration, and HRQOL were evaluated using multiple linear regression analysis in participants aged 9-10 years.

Physical fitness was measured using a series of challenges, including curl-ups (pull-ups with palms facing body), push-ups, standing long jump, handgrip strength measurement, and Progressive Aerobic Cardiovascular Endurance Run (PACER). Performing the multistage shuttle run, PACER, “requires participants to maintain the pace set by an audio signal, which progressively increases the intensity every minute.” Results of the PACER test were used to estimate VO_2max.

Concentration was measured using the d2-R test, “a paper-pencil cancellation test, where subjects have to cross out all ‘d’ letters with two dashes under a time limit.”

HRQOL was evaluated with the KINDL questionnaire, which covers emotional well-being, physical well-being, everyday functioning (school), friends, family, and self-esteem.

Analysis showed that physical fitness improved with age (P < .001), except for VO_2max in girls (P = .129). Concentration also improved with age (P < .001), while HRQOL did not (P = .179).

Among children aged 9-10 years, VO_2max scores were strongly associated with both HRQOL (P < .001) and concentration (P < .001).

“VO_2max was found to be one of the main factors influencing concentration levels and HRQOL dimensions in primary school children,” the investigators wrote. “Physical fitness, especially cardiorespiratory performance, should therefore be promoted more specifically in school settings to support the promotion of an overall healthy lifestyle in children and adolescents.”
 

Findings are having a real-word impact, according to researcher

In an interview, Ms. Köble noted that the findings are already having a real-world impact.

“We continued data assessment in the long-term and specifically adapted prevention programs in school to the needs of the school children we identified in our study,” she said. “Schools are partially offering specific movement and nutrition classes now.”

In addition, Ms. Köble and colleagues plan on educating teachers about the “urgent need for sufficient physical activity.”

“Academic performance should be considered as an additional health factor in future studies, as well as screen time and eating patterns, as all those variables showed interactions with physical fitness and concentration. In a subanalysis, we showed that children with better physical fitness and concentration values were those who usually went to higher education secondary schools,” they wrote.
 

VO_2max did not correlate with BMI

Gregory Weaver, MD, a pediatrician at Cleveland Clinic Children’s, voiced some concerns about the reliability of the findings. He noted that VO_2max did not correlate with body mass index or other measures of physical fitness, and that using the PACER test to estimate VO_2max may have skewed the association between physical fitness and concentration.

“It is quite conceivable that children who can maintain the focus to perform maximally on this test will also do well on other tests of attention/concentration,” Dr. Weaver said. “Most children I know would have a very difficult time performing a physical fitness test which requires them to match a recorded pace that slowly increases overtime. I’m not an expert in the area, but it is my understanding that usually VO_2max tests involve a treadmill which allows investigators to have complete control over pace.”

Dr. Weaver concluded that more work is needed to determine if physical fitness interventions can have a positive impact on HRQOL and concentration.

“I think the authors of this study attempted to ask an important question about the possible association between physical fitness and concentration among school aged children,” Dr. Weaver said in an interview. “But what is even more vital are studies demonstrating that a change in modifiable health factors like nutrition, physical fitness, or the built environment can improve quality of life. I was hoping the authors would show that an improvement in VO_2max over time resulted in an improvement in concentration. Frustratingly, that is not what this article demonstrates.”

The investigators and Dr. Weaver reported no conflicts of interest.

Physical exercise offers preventative and therapeutic benefits for a range of chronic health conditions, including cardiovascular disease, type 2 diabetes mellitus, Alzheimer disease, and depression.^1,2 Exercise has been well studied for its antidepressant effects, its ability to reduce risk of aging-related dementia, and favorable effects on a range of cognitive functions.² Lesser evidence exists regarding the impact of exercise on other mental health concerns. Therefore, an accurate understanding of whether physical exercise may ameliorate other conditions is important.

A small meta-analysis by Rosenbaum and colleagues found that exercise interventions were superior to control conditions for symptom reduction in study participants with posttraumatic stress disorder (PTSD).³ This meta-analysis included 4 randomized clinical trials representing 200 cases. The trial included a variety of physical activities (eg, yoga, aerobic, and strength-building exercises) and control conditions, and participants recruited from online, community, inpatient, and outpatient settings. The standardized mean difference (SMD) produced by the analysis indicated a small-to-medium effect (Hedges g, -0.35), with the authors reporting no evidence of publication bias, although an assessment of potential bias associated with individual trial design characteristics was not conducted. Of note, a meta-analysis by Watts and colleagues found that effect sizes for PTSD treatments tend to be smaller in veteran populations.⁴ Therefore, how much the mean effect size estimate in the study is applicable to veterans with PTSD is unknown.³

Veterans represent a unique subpopulation in which PTSD is common, although no meta-analysis yet published has synthesized the effects of exercise interventions from trials of veterans with PTSD.⁵ A recent systematic review by Whitworth and Ciccolo concluded that exercise may be associated with reduced risk of PTSD, a briefer course of PTSD symptoms, and/or reduced sleep- and depression-related difficulties.⁶ However, that review primarily included observational, cross-sectional, and qualitative works. No trials included in our meta-analysis were included in that review.⁶

Evidence-based psychotherapies like cognitive processing therapy and prolonged exposure have been shown to be effective for treating PTSD in veterans; however, these modalities are accompanied by high rates of dropout (eg, 40-60%), thereby limiting their clinical utility.⁷ The use of complementary and alternative approaches for treatment in the United States has increased in recent years, and exercise represents an important complementary treatment option.⁸ In a study by Baldwin and colleagues, nearly 50% of veterans reported using complementary or alternative approaches, and veterans with PTSD were among those likely to use such approaches.⁹ However, current studies of the effects of exercise interventions on PTSD symptom reduction are mostly small and varied, making determinations difficult regarding the potential utility of exercise for treating this condition in veterans.

Literature Search

No previous research has synthesized the literature on the effects of exercise on PTSD in the veteran population. The current meta-analysis aims to provide a synthesis of systematically selected studies on this topic to determine whether exercise-based interventions are effective at reducing veterans’ symptoms of PTSD. Our hypothesis was that, when used as a primary or adjuvant intervention for PTSD, physical exercise would be associated with a reduction of PTSD symptom scale scores. We planned a priori to produce separate estimates for single-arm and multi-arm trials. We also wanted to conduct a careful risk of bias assessment—or evaluation of study features that may have systematically influenced results—for included trials, not only to provide context for interpretation of results, but also to inform suggestions for research to advance this field of inquiry.¹⁰

Methods

This study was preregistered on PROSPERO and followed PRISMA guidelines for meta-analyses and systematic reviews.¹¹ Supplementary materials, such as the PRISMA checklist, study data, and funnel plots, are available online (doi.org/10.6084/m9.figshare.c.5618437.v1). Conference abstracts were omitted due to a lack of necessary information. We decided early in the planning process to include both randomized and single-arm trials, expecting the number of completed studies in the area of exercise for PTSD symptom reduction in veterans, and particularly randomized trials of such, would be relatively small.

Studies were included if they met the following criteria: (1) the study was a single- or multi-arm interventional trial; (2) participants were veterans; (3) participants had a current diagnosis of PTSD or exhibited subthreshold PTSD symptoms, as established by authors of the individual studies and supported by a structured clinical interview, semistructured interview, or elevated scores on PTSD symptom self-report measures; (4) the study included an intervention in which exercise (physical activity that is planned, structured, repetitive, and purposive in the sense that improvement or maintenance of physical fitness or health is an objective) was the primary component; (5) PTSD symptom severity was by a clinician-rated or self-report measure; and (6) the study was published in a peer-reviewed journal.¹² Studies were excluded if means, standard deviations, and sample sizes were not available or the full text of the study was not available in English.

Data Collection

Data were extracted from included studies using custom forms and included the following information based on PRISMA guidelines: (1) study design characteristics; (2) intervention details; and (3) PTSD outcome information.¹¹ PTSD symptom severity was the primary outcome of interest. Outcome data were included if they were derived from a measure of PTSD symptoms—equivalency across measures was assumed for meta-analyses. Potential study bias for each outcome was evaluated using the ROBINS-I and Cochrane Collaboration’s RoB 2 tools for single-arm and multi-arm trials, respectively.^13,14 These tools evaluate domains related to the design, conduct, and analysis of studies that are associated with bias (ie, systematic error in findings, such as under- or overestimation of results).¹⁰ Examples include how well authors performed and concealed randomization procedures, addressed missing data, and measured study outcomes.^13,14 The risk of bias (eg, low, moderate, serious) associated with each domain is rated and, based on the domain ratings, each study is then given an overall rating regarding how much risk influences bias.^13,14 Broadly, lower risk of bias corresponds to higher confidence in the validity of results.

Finally, 4 authors (associated with 2 single- and 2 multi-arm studies) were contacted and asked to provide further information. Data for 1 additional multi-arm study were obtained from these communications and included in the final study selection.¹⁵ These authors were also asked for information about any unpublished works of which they were aware, although no additional works were identified.

Statistical Analyses

Analyses were performed with R Studio R 3.6.0 software.¹⁶ An SMD (also known as Hedges g) was calculated for each study outcome: for single-arm trials, this was the SMD between pre- and postintervention scores, whereas for multi-arm trials, this was the SMD between postintervention outcome scores across groups. CIs for each SMD were calculated using a standard normal distribution. Combined SMDs were estimated separately for single- and multi-arm studies, using random-effects meta-analyses. In order to include multiple relevant outcomes from a single trial (ie, for studies using multiple PTSD symptom measures), robust variance estimation was used.¹⁷ Precision was used to weight SMDs.

Correlations between pre- and postintervention scores were not available for 1 single-arm study.¹⁸ A correlation coefficient of 0.8 was imputed to calculate the standard error of the of the SMDs for the Clinician-Administered PTSD Scale (CAPS) and the PTSD Checklist (PCL), as this value is consistent with past findings regarding the test-retest reliability of these measures.^19-22 A sensitivity analysis, using several alternative correlational values, revealed that the choice of correlation coefficient did not impact the overall results of the meta-analysis.

I² was used to evaluate between-study heterogeneity. Values of I² > 25%, 50%, and 75% were selected to reflect low, moderate, and high heterogeneity, respectively, in accordance with guidelines described by Higgins and colleagues.²³ Potential publication bias was assessed via funnel plot and Egger test.²⁴ Finally, although collection of depressive symptom scores was proposed as a secondary outcome in the study protocol, such data were available only for 1 multi-arm study. As a result, this outcome was not evaluated.

Results

Six studies with 101 total participants were included in the single-arm analyses (Table 1).^18,25-29 Participants consisted of veterans with chronic pain, post-9/11 veterans, female veterans of childbearing age, veterans with a history of trauma therapy, and other veterans. Types of exercise included moderate aerobic exercise and yoga. PTSD symptom measures included the CAPS and the PCL (PCL-5 or PCL-M versions). Reported financial sources for included studies included federal grant funding, nonprofit material support, outside organization support, use of US Department of Veterans Affairs (VA) resources, and no reported financial support.

With respect to individual studies, Shivakumar and colleagues found that completion of an aerobic exercise program was associated with reduced scores on 2 different PTSD symptom scales (PCL and CAPS) in 16 women veterans.¹⁸ A trauma-informed yoga intervention study with 18 participants by Cushing and colleagues demonstrated veteran participation to be associated with large reductions in PTSD, anxiety, and depression scale scores.²⁵ In a study with 34 veterans, Chopin and colleagues found that a trauma-informed yoga intervention was associated with a statistically significant reduction in PTSD symptoms, as did a study by Zaccari and colleagues with 17 veterans.^26,29 Justice and Brems also found some evidence that trauma-informed yoga interventions helped PTSD symptoms in a small sample of 4 veterans, although these results were not quantitatively analyzed.²⁷ In contrast, a small pilot study (n = 12) by Staples and colleagues testing a biweekly, 6-week yoga program did not show a significant effect on PTSD symptoms.²⁸

Three studies with 217 total veteran participants were included in the multi-arm analyses (Table 2).^15,30,31 As all multi-arm trials incorporated randomization, they will be referred to as randomized controlled trials (RCTs). On contact, Davis and colleagues provided veteran-specific results for their trial; as such, our data differ from those within the published article.¹⁵ Participants from all included studies were veterans currently experiencing symptoms of PTSD. Types of exercise included yoga and combined methods (eg, aerobic and strength training).^15,30,31 PTSD symptom measures included the CAPS or the PCL-5.^15,30,31 Reported financial sources for included studies included federal grant funding, as well as nonprofit support, private donations, and VA and Department of Defense resources.

Davis and colleagues conducted a recently concluded RCT with > 130 veteran participants and found that a novel manualized yoga program was superior to an attention control in reducing PTSD symptom scale scores for veterans.¹⁵ Goldstein and colleagues found that a program consisting of both aerobic and resistance exercises reduced PTSD symptoms to a greater extent than a waitlist control condition, with 47 veterans randomized in this trial.³⁰ Likewise, Hall and colleagues conducted a pilot RCT in which an intervention that integrated exercise and cognitive behavioral techniques was compared to a waitlist control condition.³¹ For the 48 veterans included in the analyses, the authors reported greater PTSD symptom reduction associated with integrated exercise than that of the control condition; however, the study was not powered to detect statistically significant differences between groups.

Bias Assessment

Results for the risk of bias assessments can be viewed in Tables 3 and 4. For single-arm studies, overall risk of bias was serious for all included trials. Serious risk of bias was found in 2 domains: confounding, due to a lack of accounting for potential preexisting baseline trends (eg, regression to the mean) that could have impacted study results; and measurement, due to the use of a self-report symptom measure (PCL) or CAPS with unblinded assessors. Multiple studies also showed moderate risk in the missing data domain due to participant dropout without appropriate analytic methods to address potential bias.

For RCTs, overall risk of bias ranged from some concerns to high risk. High risk of bias was found in 1 domain, measurement of outcome, due to use of a self-report symptom measure (PCL) with unblinded groups.³¹ The other 2 studies all had some concern of bias in at least 1 of the following domains: randomization, missing data, and measurement of outcome.

Pooled Standardized Mean Differences

Meta-analytic results can be viewed in Figure 2. The pooled SMD for the 6 single-arm studies was -0.60 (df = 4.41, 95% CI, -1.08 to -0.12, P = .03), indicating a statistically significant reduction in PTSD symptoms over the course of an exercise intervention. Combining SMDs for the 3 included RCTs revealed a pooled SMD of -0.40 (df = 1.57, 95% CI, -0.86 to 0.06, P = .06), indicating that exercise did not result in a statistically significant reduction in PTSD symptoms compared with control conditions.

Visual inspection funnel plots and Egger test did not suggest the presence of publication bias for RCTs (t = 1.21, df = 2, P = .35) or single-arm studies (t = -0.36, df = 5, P = .73).

Single-arm studies displayed a high degree of heterogeneity (I² = 81.5%). Including sample size or exercise duration as variables in meta-regressions did not reduce heterogeneity (I² = 85.2% and I² = 83.8%, respectively). Performing a subgroup analysis only on studies using yoga as an intervention also did not reduce heterogeneity (I² = 79.2%). Due to the small number of studies, no further exploration of heterogeneity was conducted on single-arm studies. RCTs did not display any heterogeneity (I² = 0%).

Discussion

Our report represents an early synthesis of the first prospective studies of physical exercise interventions for PTSD in veterans. Results from meta-analyses of 6 single-arm studies (101 participants) and 3 RCTs (217 participants) provide early evidence that exercise may reduce PTSD symptoms in veterans. Yoga was the most common form of exercise used in single-arm studies, whereas RCTs used a wider range of interventions. The pooled SMD of -0.60 for single-arm longitudinal studies suggest a medium decrease in PTSD symptoms for veterans who engage in exercise interventions. Analysis of the RCTs supported this finding, with a pooled SMD of -0.40 reflecting a small-to-medium effect of exercise on PTSD symptoms over control conditions, although this result did not achieve statistical significance. Of note, while the nonsignificant finding for RCTs may have been due to insufficient power caused by the limited number of included studies, possibly exercise was not more efficacious than were the control conditions.

Although RCTs represented a variety of exercise types, PTSD symptom measures, and veteran subgroups, statistical results were not indicative of heterogeneity. However, only the largest and most comprehensive study of exercise for PTSD in veterans to date by Davis and colleagues had a statistically significant SMD.¹⁵ Of note, one of the other 2 RCTs displayed an SMD of a similar magnitude, but this study had a much smaller sample size and was underpowered to detect significance.³⁰ Additionally, risk of bias assessments for single-arm studies and RCTs revealed study characteristics that suggest possible inflation of absolute effect sizes for individual studies. Therefore, the pooled SMDs we report are interpretable but may exceed the true effect of exercise for PTSD symptom reduction in veterans.

Limitations

The present study has several important limitations. First, few studies were found that met the broad eligibility criteria and those that did often had a small sample size. Besides highlighting a gap in the extant research, the limited studies available for meta-analysis means that caution must be taken when interpreting results. Fortunately, this issue will likely resolve once additional studies investigating the impact of exercise on PTSD symptoms in veterans are available for synthesis.

Relatedly, the included study interventions varied considerably, both in the types of exercise used and the characteristics of the exercises (eg, frequency, duration, and intensity), which is relevant as different exercise modalities are associated with differential physical effects.³³ Including such a mixture of exercises may have given an incomplete picture of their potential therapeutic effects. Also, none of the RCTs compared exercise against first-line treatments for PTSD, such as prolonged exposure or cognitive processing therapy, which would have provided further insight into the role exercise could play in clinical settings.⁷

Another limitation is the elevated risk of bias found in most studies, particularly present in the longitudinal single-arm studies, all of which were rated at serious risk. For instance, no single-arm study controlled for preexisting baseline trends: without such (and lacking a comparison control group like in RCTs), it is possible that the observed effects were due to extraneous factors, rather than the exercise intervention. Although not as severe, the multi-arm RCTs also displayed at least moderate risk of bias. Therefore, SMDs may have been overestimated for each group of studies.

Finally, the results of the single-arm meta-analysis displayed high statistical heterogeneity, reducing the generalizability of the results. One possible cause of this heterogeneity may have been the yoga interventions, as a separate analysis removing the only nonyoga study did not reduce heterogeneity. This result was surprising, as the included yoga interventions seemed similar across studies. While the presence of high heterogeneity does require some caution when applying these results to outside interventions, the present study made use of random-effects meta-analysis, a technique that incorporates study heterogeneity into the statistical model, thereby strengthening the findings compared with that of a traditional fixed-effects approach.¹⁰

Future Steps

Several future steps are warranted to improve knowledge of exercise as a treatment for PTSD in veterans and in the general population. With current meta-analyses limited to small numbers of studies, additional studies of the efficacy of exercise for treating PTSD could help in several ways. A larger pool of studies would enable future meta-analyses to explore related questions, such as those regarding the impact of exercise on quality of life or depressive symptom reduction among veterans with PTSD. A greater number of studies also would enable meta-analysts to explore potentially critical moderators. For example, the duration, frequency, or type of exercise may moderate the effect of exercise on PTSD symptom reduction. Moderators related to patient or study design characteristics also should be explored in future studies.

Future work also should evaluate the impact that specific features of exercise regimens have on PTSD. Knowing whether the type or structure of exercise affects its clinical use would be invaluable in developing and implementing efficient exercise-based interventions. For example, if facilitated exercise was found to be significantly more effective at reducing PTSD symptoms than exercise completed independently, the development of exercise intervention programs in the VA and other facilities that commonly treat PTSD may be warranted. Additionally, it may be useful to identify specific mechanisms through which exercise reduces PTSD symptoms. For example, in addition to its beneficial biological effects, exercise also promotes psychological health through behavioral activation and alterations within reinforcement/reward systems, suggesting that exercise regularity may be more important than intensity.^34,35 Understanding which mechanisms contribute most to change will aid in the development of more efficient interventions.

Given that veterans are demonstrating considerable interest in complementary and alternative PTSD treatments, it is critical that researchers focus on high-quality randomized tests of these interventions. Therefore, in addition to greater quality of exercise intervention studies, future efforts should be focused on RCTs that are designed in such a way as to limit potential introduction of bias. For example, assessment data should be completed by blinded assessors using standardized measures, and analyses should account for missing data and unequal participant attrition between groups. Ideally, pre-intervention trends across multiple baseline datapoints also would be collected in single-arm studies to avoid confounding related to regression to the mean. It is also recommended that future meta-analyses use risk of bias assessments and consider how the results of such assessments may impact the interpretation of results.

Conclusions

Findings from both single-arm studies and RCTs suggest possible benefit of exercise on PTSD symptom reduction, although confirmation of findings is needed. No study found increased symptoms following exercise intervention. Thus, it is reasonable to consider physical exercise, such as yoga, as an adjunct, whole-health consistent treatment. HCPs working with veterans with past traumatic experiences should consider incorporating exercise into patient care. Enhanced educational efforts emphasizing the psychotherapeutic impact of exercise may also have value for the veteran population. Furthermore, the current risk of bias assessments highlights the need for additional high-quality RCTs evaluating the specific impact of exercise on PTSD symptom reduction in veterans. In particular, this field of inquiry would benefit from larger samples and design characteristics to reduce bias (eg, blinding when possible, use of CAPS vs only self-report symptom measures, reducing problematic attrition, corrections for missing data, etc).

Physical exercise offers preventative and therapeutic benefits for a range of chronic health conditions, including cardiovascular disease, type 2 diabetes mellitus, Alzheimer disease, and depression.^1,2 Exercise has been well studied for its antidepressant effects, its ability to reduce risk of aging-related dementia, and favorable effects on a range of cognitive functions.² Lesser evidence exists regarding the impact of exercise on other mental health concerns. Therefore, an accurate understanding of whether physical exercise may ameliorate other conditions is important.

A small meta-analysis by Rosenbaum and colleagues found that exercise interventions were superior to control conditions for symptom reduction in study participants with posttraumatic stress disorder (PTSD).³ This meta-analysis included 4 randomized clinical trials representing 200 cases. The trial included a variety of physical activities (eg, yoga, aerobic, and strength-building exercises) and control conditions, and participants recruited from online, community, inpatient, and outpatient settings. The standardized mean difference (SMD) produced by the analysis indicated a small-to-medium effect (Hedges g, -0.35), with the authors reporting no evidence of publication bias, although an assessment of potential bias associated with individual trial design characteristics was not conducted. Of note, a meta-analysis by Watts and colleagues found that effect sizes for PTSD treatments tend to be smaller in veteran populations.⁴ Therefore, how much the mean effect size estimate in the study is applicable to veterans with PTSD is unknown.³

Veterans represent a unique subpopulation in which PTSD is common, although no meta-analysis yet published has synthesized the effects of exercise interventions from trials of veterans with PTSD.⁵ A recent systematic review by Whitworth and Ciccolo concluded that exercise may be associated with reduced risk of PTSD, a briefer course of PTSD symptoms, and/or reduced sleep- and depression-related difficulties.⁶ However, that review primarily included observational, cross-sectional, and qualitative works. No trials included in our meta-analysis were included in that review.⁶

Evidence-based psychotherapies like cognitive processing therapy and prolonged exposure have been shown to be effective for treating PTSD in veterans; however, these modalities are accompanied by high rates of dropout (eg, 40-60%), thereby limiting their clinical utility.⁷ The use of complementary and alternative approaches for treatment in the United States has increased in recent years, and exercise represents an important complementary treatment option.⁸ In a study by Baldwin and colleagues, nearly 50% of veterans reported using complementary or alternative approaches, and veterans with PTSD were among those likely to use such approaches.⁹ However, current studies of the effects of exercise interventions on PTSD symptom reduction are mostly small and varied, making determinations difficult regarding the potential utility of exercise for treating this condition in veterans.

Literature Search

No previous research has synthesized the literature on the effects of exercise on PTSD in the veteran population. The current meta-analysis aims to provide a synthesis of systematically selected studies on this topic to determine whether exercise-based interventions are effective at reducing veterans’ symptoms of PTSD. Our hypothesis was that, when used as a primary or adjuvant intervention for PTSD, physical exercise would be associated with a reduction of PTSD symptom scale scores. We planned a priori to produce separate estimates for single-arm and multi-arm trials. We also wanted to conduct a careful risk of bias assessment—or evaluation of study features that may have systematically influenced results—for included trials, not only to provide context for interpretation of results, but also to inform suggestions for research to advance this field of inquiry.¹⁰

Methods

This study was preregistered on PROSPERO and followed PRISMA guidelines for meta-analyses and systematic reviews.¹¹ Supplementary materials, such as the PRISMA checklist, study data, and funnel plots, are available online (doi.org/10.6084/m9.figshare.c.5618437.v1). Conference abstracts were omitted due to a lack of necessary information. We decided early in the planning process to include both randomized and single-arm trials, expecting the number of completed studies in the area of exercise for PTSD symptom reduction in veterans, and particularly randomized trials of such, would be relatively small.

Studies were included if they met the following criteria: (1) the study was a single- or multi-arm interventional trial; (2) participants were veterans; (3) participants had a current diagnosis of PTSD or exhibited subthreshold PTSD symptoms, as established by authors of the individual studies and supported by a structured clinical interview, semistructured interview, or elevated scores on PTSD symptom self-report measures; (4) the study included an intervention in which exercise (physical activity that is planned, structured, repetitive, and purposive in the sense that improvement or maintenance of physical fitness or health is an objective) was the primary component; (5) PTSD symptom severity was by a clinician-rated or self-report measure; and (6) the study was published in a peer-reviewed journal.¹² Studies were excluded if means, standard deviations, and sample sizes were not available or the full text of the study was not available in English.

Data Collection

Data were extracted from included studies using custom forms and included the following information based on PRISMA guidelines: (1) study design characteristics; (2) intervention details; and (3) PTSD outcome information.¹¹ PTSD symptom severity was the primary outcome of interest. Outcome data were included if they were derived from a measure of PTSD symptoms—equivalency across measures was assumed for meta-analyses. Potential study bias for each outcome was evaluated using the ROBINS-I and Cochrane Collaboration’s RoB 2 tools for single-arm and multi-arm trials, respectively.^13,14 These tools evaluate domains related to the design, conduct, and analysis of studies that are associated with bias (ie, systematic error in findings, such as under- or overestimation of results).¹⁰ Examples include how well authors performed and concealed randomization procedures, addressed missing data, and measured study outcomes.^13,14 The risk of bias (eg, low, moderate, serious) associated with each domain is rated and, based on the domain ratings, each study is then given an overall rating regarding how much risk influences bias.^13,14 Broadly, lower risk of bias corresponds to higher confidence in the validity of results.

Finally, 4 authors (associated with 2 single- and 2 multi-arm studies) were contacted and asked to provide further information. Data for 1 additional multi-arm study were obtained from these communications and included in the final study selection.¹⁵ These authors were also asked for information about any unpublished works of which they were aware, although no additional works were identified.

Statistical Analyses

Analyses were performed with R Studio R 3.6.0 software.¹⁶ An SMD (also known as Hedges g) was calculated for each study outcome: for single-arm trials, this was the SMD between pre- and postintervention scores, whereas for multi-arm trials, this was the SMD between postintervention outcome scores across groups. CIs for each SMD were calculated using a standard normal distribution. Combined SMDs were estimated separately for single- and multi-arm studies, using random-effects meta-analyses. In order to include multiple relevant outcomes from a single trial (ie, for studies using multiple PTSD symptom measures), robust variance estimation was used.¹⁷ Precision was used to weight SMDs.

Correlations between pre- and postintervention scores were not available for 1 single-arm study.¹⁸ A correlation coefficient of 0.8 was imputed to calculate the standard error of the of the SMDs for the Clinician-Administered PTSD Scale (CAPS) and the PTSD Checklist (PCL), as this value is consistent with past findings regarding the test-retest reliability of these measures.^19-22 A sensitivity analysis, using several alternative correlational values, revealed that the choice of correlation coefficient did not impact the overall results of the meta-analysis.

I² was used to evaluate between-study heterogeneity. Values of I² > 25%, 50%, and 75% were selected to reflect low, moderate, and high heterogeneity, respectively, in accordance with guidelines described by Higgins and colleagues.²³ Potential publication bias was assessed via funnel plot and Egger test.²⁴ Finally, although collection of depressive symptom scores was proposed as a secondary outcome in the study protocol, such data were available only for 1 multi-arm study. As a result, this outcome was not evaluated.

Results

Six studies with 101 total participants were included in the single-arm analyses (Table 1).^18,25-29 Participants consisted of veterans with chronic pain, post-9/11 veterans, female veterans of childbearing age, veterans with a history of trauma therapy, and other veterans. Types of exercise included moderate aerobic exercise and yoga. PTSD symptom measures included the CAPS and the PCL (PCL-5 or PCL-M versions). Reported financial sources for included studies included federal grant funding, nonprofit material support, outside organization support, use of US Department of Veterans Affairs (VA) resources, and no reported financial support.

With respect to individual studies, Shivakumar and colleagues found that completion of an aerobic exercise program was associated with reduced scores on 2 different PTSD symptom scales (PCL and CAPS) in 16 women veterans.¹⁸ A trauma-informed yoga intervention study with 18 participants by Cushing and colleagues demonstrated veteran participation to be associated with large reductions in PTSD, anxiety, and depression scale scores.²⁵ In a study with 34 veterans, Chopin and colleagues found that a trauma-informed yoga intervention was associated with a statistically significant reduction in PTSD symptoms, as did a study by Zaccari and colleagues with 17 veterans.^26,29 Justice and Brems also found some evidence that trauma-informed yoga interventions helped PTSD symptoms in a small sample of 4 veterans, although these results were not quantitatively analyzed.²⁷ In contrast, a small pilot study (n = 12) by Staples and colleagues testing a biweekly, 6-week yoga program did not show a significant effect on PTSD symptoms.²⁸

Three studies with 217 total veteran participants were included in the multi-arm analyses (Table 2).^15,30,31 As all multi-arm trials incorporated randomization, they will be referred to as randomized controlled trials (RCTs). On contact, Davis and colleagues provided veteran-specific results for their trial; as such, our data differ from those within the published article.¹⁵ Participants from all included studies were veterans currently experiencing symptoms of PTSD. Types of exercise included yoga and combined methods (eg, aerobic and strength training).^15,30,31 PTSD symptom measures included the CAPS or the PCL-5.^15,30,31 Reported financial sources for included studies included federal grant funding, as well as nonprofit support, private donations, and VA and Department of Defense resources.

Davis and colleagues conducted a recently concluded RCT with > 130 veteran participants and found that a novel manualized yoga program was superior to an attention control in reducing PTSD symptom scale scores for veterans.¹⁵ Goldstein and colleagues found that a program consisting of both aerobic and resistance exercises reduced PTSD symptoms to a greater extent than a waitlist control condition, with 47 veterans randomized in this trial.³⁰ Likewise, Hall and colleagues conducted a pilot RCT in which an intervention that integrated exercise and cognitive behavioral techniques was compared to a waitlist control condition.³¹ For the 48 veterans included in the analyses, the authors reported greater PTSD symptom reduction associated with integrated exercise than that of the control condition; however, the study was not powered to detect statistically significant differences between groups.

Bias Assessment

Results for the risk of bias assessments can be viewed in Tables 3 and 4. For single-arm studies, overall risk of bias was serious for all included trials. Serious risk of bias was found in 2 domains: confounding, due to a lack of accounting for potential preexisting baseline trends (eg, regression to the mean) that could have impacted study results; and measurement, due to the use of a self-report symptom measure (PCL) or CAPS with unblinded assessors. Multiple studies also showed moderate risk in the missing data domain due to participant dropout without appropriate analytic methods to address potential bias.

For RCTs, overall risk of bias ranged from some concerns to high risk. High risk of bias was found in 1 domain, measurement of outcome, due to use of a self-report symptom measure (PCL) with unblinded groups.³¹ The other 2 studies all had some concern of bias in at least 1 of the following domains: randomization, missing data, and measurement of outcome.

Pooled Standardized Mean Differences

Meta-analytic results can be viewed in Figure 2. The pooled SMD for the 6 single-arm studies was -0.60 (df = 4.41, 95% CI, -1.08 to -0.12, P = .03), indicating a statistically significant reduction in PTSD symptoms over the course of an exercise intervention. Combining SMDs for the 3 included RCTs revealed a pooled SMD of -0.40 (df = 1.57, 95% CI, -0.86 to 0.06, P = .06), indicating that exercise did not result in a statistically significant reduction in PTSD symptoms compared with control conditions.

Publication Bias and Heterogeneity

Visual inspection funnel plots and Egger test did not suggest the presence of publication bias for RCTs (t = 1.21, df = 2, P = .35) or single-arm studies (t = -0.36, df = 5, P = .73).

Single-arm studies displayed a high degree of heterogeneity (I² = 81.5%). Including sample size or exercise duration as variables in meta-regressions did not reduce heterogeneity (I² = 85.2% and I² = 83.8%, respectively). Performing a subgroup analysis only on studies using yoga as an intervention also did not reduce heterogeneity (I² = 79.2%). Due to the small number of studies, no further exploration of heterogeneity was conducted on single-arm studies. RCTs did not display any heterogeneity (I² = 0%).

Discussion

Our report represents an early synthesis of the first prospective studies of physical exercise interventions for PTSD in veterans. Results from meta-analyses of 6 single-arm studies (101 participants) and 3 RCTs (217 participants) provide early evidence that exercise may reduce PTSD symptoms in veterans. Yoga was the most common form of exercise used in single-arm studies, whereas RCTs used a wider range of interventions. The pooled SMD of -0.60 for single-arm longitudinal studies suggest a medium decrease in PTSD symptoms for veterans who engage in exercise interventions. Analysis of the RCTs supported this finding, with a pooled SMD of -0.40 reflecting a small-to-medium effect of exercise on PTSD symptoms over control conditions, although this result did not achieve statistical significance. Of note, while the nonsignificant finding for RCTs may have been due to insufficient power caused by the limited number of included studies, possibly exercise was not more efficacious than were the control conditions.

Although RCTs represented a variety of exercise types, PTSD symptom measures, and veteran subgroups, statistical results were not indicative of heterogeneity. However, only the largest and most comprehensive study of exercise for PTSD in veterans to date by Davis and colleagues had a statistically significant SMD.¹⁵ Of note, one of the other 2 RCTs displayed an SMD of a similar magnitude, but this study had a much smaller sample size and was underpowered to detect significance.³⁰ Additionally, risk of bias assessments for single-arm studies and RCTs revealed study characteristics that suggest possible inflation of absolute effect sizes for individual studies. Therefore, the pooled SMDs we report are interpretable but may exceed the true effect of exercise for PTSD symptom reduction in veterans.

Limitations

The present study has several important limitations. First, few studies were found that met the broad eligibility criteria and those that did often had a small sample size. Besides highlighting a gap in the extant research, the limited studies available for meta-analysis means that caution must be taken when interpreting results. Fortunately, this issue will likely resolve once additional studies investigating the impact of exercise on PTSD symptoms in veterans are available for synthesis.

Relatedly, the included study interventions varied considerably, both in the types of exercise used and the characteristics of the exercises (eg, frequency, duration, and intensity), which is relevant as different exercise modalities are associated with differential physical effects.³³ Including such a mixture of exercises may have given an incomplete picture of their potential therapeutic effects. Also, none of the RCTs compared exercise against first-line treatments for PTSD, such as prolonged exposure or cognitive processing therapy, which would have provided further insight into the role exercise could play in clinical settings.⁷

Another limitation is the elevated risk of bias found in most studies, particularly present in the longitudinal single-arm studies, all of which were rated at serious risk. For instance, no single-arm study controlled for preexisting baseline trends: without such (and lacking a comparison control group like in RCTs), it is possible that the observed effects were due to extraneous factors, rather than the exercise intervention. Although not as severe, the multi-arm RCTs also displayed at least moderate risk of bias. Therefore, SMDs may have been overestimated for each group of studies.

Finally, the results of the single-arm meta-analysis displayed high statistical heterogeneity, reducing the generalizability of the results. One possible cause of this heterogeneity may have been the yoga interventions, as a separate analysis removing the only nonyoga study did not reduce heterogeneity. This result was surprising, as the included yoga interventions seemed similar across studies. While the presence of high heterogeneity does require some caution when applying these results to outside interventions, the present study made use of random-effects meta-analysis, a technique that incorporates study heterogeneity into the statistical model, thereby strengthening the findings compared with that of a traditional fixed-effects approach.¹⁰

Future Steps

Several future steps are warranted to improve knowledge of exercise as a treatment for PTSD in veterans and in the general population. With current meta-analyses limited to small numbers of studies, additional studies of the efficacy of exercise for treating PTSD could help in several ways. A larger pool of studies would enable future meta-analyses to explore related questions, such as those regarding the impact of exercise on quality of life or depressive symptom reduction among veterans with PTSD. A greater number of studies also would enable meta-analysts to explore potentially critical moderators. For example, the duration, frequency, or type of exercise may moderate the effect of exercise on PTSD symptom reduction. Moderators related to patient or study design characteristics also should be explored in future studies.

Future work also should evaluate the impact that specific features of exercise regimens have on PTSD. Knowing whether the type or structure of exercise affects its clinical use would be invaluable in developing and implementing efficient exercise-based interventions. For example, if facilitated exercise was found to be significantly more effective at reducing PTSD symptoms than exercise completed independently, the development of exercise intervention programs in the VA and other facilities that commonly treat PTSD may be warranted. Additionally, it may be useful to identify specific mechanisms through which exercise reduces PTSD symptoms. For example, in addition to its beneficial biological effects, exercise also promotes psychological health through behavioral activation and alterations within reinforcement/reward systems, suggesting that exercise regularity may be more important than intensity.^34,35 Understanding which mechanisms contribute most to change will aid in the development of more efficient interventions.

Given that veterans are demonstrating considerable interest in complementary and alternative PTSD treatments, it is critical that researchers focus on high-quality randomized tests of these interventions. Therefore, in addition to greater quality of exercise intervention studies, future efforts should be focused on RCTs that are designed in such a way as to limit potential introduction of bias. For example, assessment data should be completed by blinded assessors using standardized measures, and analyses should account for missing data and unequal participant attrition between groups. Ideally, pre-intervention trends across multiple baseline datapoints also would be collected in single-arm studies to avoid confounding related to regression to the mean. It is also recommended that future meta-analyses use risk of bias assessments and consider how the results of such assessments may impact the interpretation of results.

Conclusions

Findings from both single-arm studies and RCTs suggest possible benefit of exercise on PTSD symptom reduction, although confirmation of findings is needed. No study found increased symptoms following exercise intervention. Thus, it is reasonable to consider physical exercise, such as yoga, as an adjunct, whole-health consistent treatment. HCPs working with veterans with past traumatic experiences should consider incorporating exercise into patient care. Enhanced educational efforts emphasizing the psychotherapeutic impact of exercise may also have value for the veteran population. Furthermore, the current risk of bias assessments highlights the need for additional high-quality RCTs evaluating the specific impact of exercise on PTSD symptom reduction in veterans. In particular, this field of inquiry would benefit from larger samples and design characteristics to reduce bias (eg, blinding when possible, use of CAPS vs only self-report symptom measures, reducing problematic attrition, corrections for missing data, etc).

Physical exercise offers preventative and therapeutic benefits for a range of chronic health conditions, including cardiovascular disease, type 2 diabetes mellitus, Alzheimer disease, and depression.^1,2 Exercise has been well studied for its antidepressant effects, its ability to reduce risk of aging-related dementia, and favorable effects on a range of cognitive functions.² Lesser evidence exists regarding the impact of exercise on other mental health concerns. Therefore, an accurate understanding of whether physical exercise may ameliorate other conditions is important.

A small meta-analysis by Rosenbaum and colleagues found that exercise interventions were superior to control conditions for symptom reduction in study participants with posttraumatic stress disorder (PTSD).³ This meta-analysis included 4 randomized clinical trials representing 200 cases. The trial included a variety of physical activities (eg, yoga, aerobic, and strength-building exercises) and control conditions, and participants recruited from online, community, inpatient, and outpatient settings. The standardized mean difference (SMD) produced by the analysis indicated a small-to-medium effect (Hedges g, -0.35), with the authors reporting no evidence of publication bias, although an assessment of potential bias associated with individual trial design characteristics was not conducted. Of note, a meta-analysis by Watts and colleagues found that effect sizes for PTSD treatments tend to be smaller in veteran populations.⁴ Therefore, how much the mean effect size estimate in the study is applicable to veterans with PTSD is unknown.³

Veterans represent a unique subpopulation in which PTSD is common, although no meta-analysis yet published has synthesized the effects of exercise interventions from trials of veterans with PTSD.⁵ A recent systematic review by Whitworth and Ciccolo concluded that exercise may be associated with reduced risk of PTSD, a briefer course of PTSD symptoms, and/or reduced sleep- and depression-related difficulties.⁶ However, that review primarily included observational, cross-sectional, and qualitative works. No trials included in our meta-analysis were included in that review.⁶

Evidence-based psychotherapies like cognitive processing therapy and prolonged exposure have been shown to be effective for treating PTSD in veterans; however, these modalities are accompanied by high rates of dropout (eg, 40-60%), thereby limiting their clinical utility.⁷ The use of complementary and alternative approaches for treatment in the United States has increased in recent years, and exercise represents an important complementary treatment option.⁸ In a study by Baldwin and colleagues, nearly 50% of veterans reported using complementary or alternative approaches, and veterans with PTSD were among those likely to use such approaches.⁹ However, current studies of the effects of exercise interventions on PTSD symptom reduction are mostly small and varied, making determinations difficult regarding the potential utility of exercise for treating this condition in veterans.

Literature Search

No previous research has synthesized the literature on the effects of exercise on PTSD in the veteran population. The current meta-analysis aims to provide a synthesis of systematically selected studies on this topic to determine whether exercise-based interventions are effective at reducing veterans’ symptoms of PTSD. Our hypothesis was that, when used as a primary or adjuvant intervention for PTSD, physical exercise would be associated with a reduction of PTSD symptom scale scores. We planned a priori to produce separate estimates for single-arm and multi-arm trials. We also wanted to conduct a careful risk of bias assessment—or evaluation of study features that may have systematically influenced results—for included trials, not only to provide context for interpretation of results, but also to inform suggestions for research to advance this field of inquiry.¹⁰

Methods

This study was preregistered on PROSPERO and followed PRISMA guidelines for meta-analyses and systematic reviews.¹¹ Supplementary materials, such as the PRISMA checklist, study data, and funnel plots, are available online (doi.org/10.6084/m9.figshare.c.5618437.v1). Conference abstracts were omitted due to a lack of necessary information. We decided early in the planning process to include both randomized and single-arm trials, expecting the number of completed studies in the area of exercise for PTSD symptom reduction in veterans, and particularly randomized trials of such, would be relatively small.

Studies were included if they met the following criteria: (1) the study was a single- or multi-arm interventional trial; (2) participants were veterans; (3) participants had a current diagnosis of PTSD or exhibited subthreshold PTSD symptoms, as established by authors of the individual studies and supported by a structured clinical interview, semistructured interview, or elevated scores on PTSD symptom self-report measures; (4) the study included an intervention in which exercise (physical activity that is planned, structured, repetitive, and purposive in the sense that improvement or maintenance of physical fitness or health is an objective) was the primary component; (5) PTSD symptom severity was by a clinician-rated or self-report measure; and (6) the study was published in a peer-reviewed journal.¹² Studies were excluded if means, standard deviations, and sample sizes were not available or the full text of the study was not available in English.

Data Collection

Data were extracted from included studies using custom forms and included the following information based on PRISMA guidelines: (1) study design characteristics; (2) intervention details; and (3) PTSD outcome information.¹¹ PTSD symptom severity was the primary outcome of interest. Outcome data were included if they were derived from a measure of PTSD symptoms—equivalency across measures was assumed for meta-analyses. Potential study bias for each outcome was evaluated using the ROBINS-I and Cochrane Collaboration’s RoB 2 tools for single-arm and multi-arm trials, respectively.^13,14 These tools evaluate domains related to the design, conduct, and analysis of studies that are associated with bias (ie, systematic error in findings, such as under- or overestimation of results).¹⁰ Examples include how well authors performed and concealed randomization procedures, addressed missing data, and measured study outcomes.^13,14 The risk of bias (eg, low, moderate, serious) associated with each domain is rated and, based on the domain ratings, each study is then given an overall rating regarding how much risk influences bias.^13,14 Broadly, lower risk of bias corresponds to higher confidence in the validity of results.

Finally, 4 authors (associated with 2 single- and 2 multi-arm studies) were contacted and asked to provide further information. Data for 1 additional multi-arm study were obtained from these communications and included in the final study selection.¹⁵ These authors were also asked for information about any unpublished works of which they were aware, although no additional works were identified.

Statistical Analyses

Analyses were performed with R Studio R 3.6.0 software.¹⁶ An SMD (also known as Hedges g) was calculated for each study outcome: for single-arm trials, this was the SMD between pre- and postintervention scores, whereas for multi-arm trials, this was the SMD between postintervention outcome scores across groups. CIs for each SMD were calculated using a standard normal distribution. Combined SMDs were estimated separately for single- and multi-arm studies, using random-effects meta-analyses. In order to include multiple relevant outcomes from a single trial (ie, for studies using multiple PTSD symptom measures), robust variance estimation was used.¹⁷ Precision was used to weight SMDs.

Correlations between pre- and postintervention scores were not available for 1 single-arm study.¹⁸ A correlation coefficient of 0.8 was imputed to calculate the standard error of the of the SMDs for the Clinician-Administered PTSD Scale (CAPS) and the PTSD Checklist (PCL), as this value is consistent with past findings regarding the test-retest reliability of these measures.^19-22 A sensitivity analysis, using several alternative correlational values, revealed that the choice of correlation coefficient did not impact the overall results of the meta-analysis.

I² was used to evaluate between-study heterogeneity. Values of I² > 25%, 50%, and 75% were selected to reflect low, moderate, and high heterogeneity, respectively, in accordance with guidelines described by Higgins and colleagues.²³ Potential publication bias was assessed via funnel plot and Egger test.²⁴ Finally, although collection of depressive symptom scores was proposed as a secondary outcome in the study protocol, such data were available only for 1 multi-arm study. As a result, this outcome was not evaluated.

Results

Six studies with 101 total participants were included in the single-arm analyses (Table 1).^18,25-29 Participants consisted of veterans with chronic pain, post-9/11 veterans, female veterans of childbearing age, veterans with a history of trauma therapy, and other veterans. Types of exercise included moderate aerobic exercise and yoga. PTSD symptom measures included the CAPS and the PCL (PCL-5 or PCL-M versions). Reported financial sources for included studies included federal grant funding, nonprofit material support, outside organization support, use of US Department of Veterans Affairs (VA) resources, and no reported financial support.

With respect to individual studies, Shivakumar and colleagues found that completion of an aerobic exercise program was associated with reduced scores on 2 different PTSD symptom scales (PCL and CAPS) in 16 women veterans.¹⁸ A trauma-informed yoga intervention study with 18 participants by Cushing and colleagues demonstrated veteran participation to be associated with large reductions in PTSD, anxiety, and depression scale scores.²⁵ In a study with 34 veterans, Chopin and colleagues found that a trauma-informed yoga intervention was associated with a statistically significant reduction in PTSD symptoms, as did a study by Zaccari and colleagues with 17 veterans.^26,29 Justice and Brems also found some evidence that trauma-informed yoga interventions helped PTSD symptoms in a small sample of 4 veterans, although these results were not quantitatively analyzed.²⁷ In contrast, a small pilot study (n = 12) by Staples and colleagues testing a biweekly, 6-week yoga program did not show a significant effect on PTSD symptoms.²⁸

Three studies with 217 total veteran participants were included in the multi-arm analyses (Table 2).^15,30,31 As all multi-arm trials incorporated randomization, they will be referred to as randomized controlled trials (RCTs). On contact, Davis and colleagues provided veteran-specific results for their trial; as such, our data differ from those within the published article.¹⁵ Participants from all included studies were veterans currently experiencing symptoms of PTSD. Types of exercise included yoga and combined methods (eg, aerobic and strength training).^15,30,31 PTSD symptom measures included the CAPS or the PCL-5.^15,30,31 Reported financial sources for included studies included federal grant funding, as well as nonprofit support, private donations, and VA and Department of Defense resources.

Davis and colleagues conducted a recently concluded RCT with > 130 veteran participants and found that a novel manualized yoga program was superior to an attention control in reducing PTSD symptom scale scores for veterans.¹⁵ Goldstein and colleagues found that a program consisting of both aerobic and resistance exercises reduced PTSD symptoms to a greater extent than a waitlist control condition, with 47 veterans randomized in this trial.³⁰ Likewise, Hall and colleagues conducted a pilot RCT in which an intervention that integrated exercise and cognitive behavioral techniques was compared to a waitlist control condition.³¹ For the 48 veterans included in the analyses, the authors reported greater PTSD symptom reduction associated with integrated exercise than that of the control condition; however, the study was not powered to detect statistically significant differences between groups.

Bias Assessment

Results for the risk of bias assessments can be viewed in Tables 3 and 4. For single-arm studies, overall risk of bias was serious for all included trials. Serious risk of bias was found in 2 domains: confounding, due to a lack of accounting for potential preexisting baseline trends (eg, regression to the mean) that could have impacted study results; and measurement, due to the use of a self-report symptom measure (PCL) or CAPS with unblinded assessors. Multiple studies also showed moderate risk in the missing data domain due to participant dropout without appropriate analytic methods to address potential bias.

For RCTs, overall risk of bias ranged from some concerns to high risk. High risk of bias was found in 1 domain, measurement of outcome, due to use of a self-report symptom measure (PCL) with unblinded groups.³¹ The other 2 studies all had some concern of bias in at least 1 of the following domains: randomization, missing data, and measurement of outcome.

Pooled Standardized Mean Differences

Meta-analytic results can be viewed in Figure 2. The pooled SMD for the 6 single-arm studies was -0.60 (df = 4.41, 95% CI, -1.08 to -0.12, P = .03), indicating a statistically significant reduction in PTSD symptoms over the course of an exercise intervention. Combining SMDs for the 3 included RCTs revealed a pooled SMD of -0.40 (df = 1.57, 95% CI, -0.86 to 0.06, P = .06), indicating that exercise did not result in a statistically significant reduction in PTSD symptoms compared with control conditions.

Publication Bias and Heterogeneity

Visual inspection funnel plots and Egger test did not suggest the presence of publication bias for RCTs (t = 1.21, df = 2, P = .35) or single-arm studies (t = -0.36, df = 5, P = .73).

Single-arm studies displayed a high degree of heterogeneity (I² = 81.5%). Including sample size or exercise duration as variables in meta-regressions did not reduce heterogeneity (I² = 85.2% and I² = 83.8%, respectively). Performing a subgroup analysis only on studies using yoga as an intervention also did not reduce heterogeneity (I² = 79.2%). Due to the small number of studies, no further exploration of heterogeneity was conducted on single-arm studies. RCTs did not display any heterogeneity (I² = 0%).

Discussion

Our report represents an early synthesis of the first prospective studies of physical exercise interventions for PTSD in veterans. Results from meta-analyses of 6 single-arm studies (101 participants) and 3 RCTs (217 participants) provide early evidence that exercise may reduce PTSD symptoms in veterans. Yoga was the most common form of exercise used in single-arm studies, whereas RCTs used a wider range of interventions. The pooled SMD of -0.60 for single-arm longitudinal studies suggest a medium decrease in PTSD symptoms for veterans who engage in exercise interventions. Analysis of the RCTs supported this finding, with a pooled SMD of -0.40 reflecting a small-to-medium effect of exercise on PTSD symptoms over control conditions, although this result did not achieve statistical significance. Of note, while the nonsignificant finding for RCTs may have been due to insufficient power caused by the limited number of included studies, possibly exercise was not more efficacious than were the control conditions.

Although RCTs represented a variety of exercise types, PTSD symptom measures, and veteran subgroups, statistical results were not indicative of heterogeneity. However, only the largest and most comprehensive study of exercise for PTSD in veterans to date by Davis and colleagues had a statistically significant SMD.¹⁵ Of note, one of the other 2 RCTs displayed an SMD of a similar magnitude, but this study had a much smaller sample size and was underpowered to detect significance.³⁰ Additionally, risk of bias assessments for single-arm studies and RCTs revealed study characteristics that suggest possible inflation of absolute effect sizes for individual studies. Therefore, the pooled SMDs we report are interpretable but may exceed the true effect of exercise for PTSD symptom reduction in veterans.

Limitations

The present study has several important limitations. First, few studies were found that met the broad eligibility criteria and those that did often had a small sample size. Besides highlighting a gap in the extant research, the limited studies available for meta-analysis means that caution must be taken when interpreting results. Fortunately, this issue will likely resolve once additional studies investigating the impact of exercise on PTSD symptoms in veterans are available for synthesis.

Relatedly, the included study interventions varied considerably, both in the types of exercise used and the characteristics of the exercises (eg, frequency, duration, and intensity), which is relevant as different exercise modalities are associated with differential physical effects.³³ Including such a mixture of exercises may have given an incomplete picture of their potential therapeutic effects. Also, none of the RCTs compared exercise against first-line treatments for PTSD, such as prolonged exposure or cognitive processing therapy, which would have provided further insight into the role exercise could play in clinical settings.⁷

Another limitation is the elevated risk of bias found in most studies, particularly present in the longitudinal single-arm studies, all of which were rated at serious risk. For instance, no single-arm study controlled for preexisting baseline trends: without such (and lacking a comparison control group like in RCTs), it is possible that the observed effects were due to extraneous factors, rather than the exercise intervention. Although not as severe, the multi-arm RCTs also displayed at least moderate risk of bias. Therefore, SMDs may have been overestimated for each group of studies.

Finally, the results of the single-arm meta-analysis displayed high statistical heterogeneity, reducing the generalizability of the results. One possible cause of this heterogeneity may have been the yoga interventions, as a separate analysis removing the only nonyoga study did not reduce heterogeneity. This result was surprising, as the included yoga interventions seemed similar across studies. While the presence of high heterogeneity does require some caution when applying these results to outside interventions, the present study made use of random-effects meta-analysis, a technique that incorporates study heterogeneity into the statistical model, thereby strengthening the findings compared with that of a traditional fixed-effects approach.¹⁰

Future Steps

Several future steps are warranted to improve knowledge of exercise as a treatment for PTSD in veterans and in the general population. With current meta-analyses limited to small numbers of studies, additional studies of the efficacy of exercise for treating PTSD could help in several ways. A larger pool of studies would enable future meta-analyses to explore related questions, such as those regarding the impact of exercise on quality of life or depressive symptom reduction among veterans with PTSD. A greater number of studies also would enable meta-analysts to explore potentially critical moderators. For example, the duration, frequency, or type of exercise may moderate the effect of exercise on PTSD symptom reduction. Moderators related to patient or study design characteristics also should be explored in future studies.

Future work also should evaluate the impact that specific features of exercise regimens have on PTSD. Knowing whether the type or structure of exercise affects its clinical use would be invaluable in developing and implementing efficient exercise-based interventions. For example, if facilitated exercise was found to be significantly more effective at reducing PTSD symptoms than exercise completed independently, the development of exercise intervention programs in the VA and other facilities that commonly treat PTSD may be warranted. Additionally, it may be useful to identify specific mechanisms through which exercise reduces PTSD symptoms. For example, in addition to its beneficial biological effects, exercise also promotes psychological health through behavioral activation and alterations within reinforcement/reward systems, suggesting that exercise regularity may be more important than intensity.^34,35 Understanding which mechanisms contribute most to change will aid in the development of more efficient interventions.

Given that veterans are demonstrating considerable interest in complementary and alternative PTSD treatments, it is critical that researchers focus on high-quality randomized tests of these interventions. Therefore, in addition to greater quality of exercise intervention studies, future efforts should be focused on RCTs that are designed in such a way as to limit potential introduction of bias. For example, assessment data should be completed by blinded assessors using standardized measures, and analyses should account for missing data and unequal participant attrition between groups. Ideally, pre-intervention trends across multiple baseline datapoints also would be collected in single-arm studies to avoid confounding related to regression to the mean. It is also recommended that future meta-analyses use risk of bias assessments and consider how the results of such assessments may impact the interpretation of results.

Conclusions

Findings from both single-arm studies and RCTs suggest possible benefit of exercise on PTSD symptom reduction, although confirmation of findings is needed. No study found increased symptoms following exercise intervention. Thus, it is reasonable to consider physical exercise, such as yoga, as an adjunct, whole-health consistent treatment. HCPs working with veterans with past traumatic experiences should consider incorporating exercise into patient care. Enhanced educational efforts emphasizing the psychotherapeutic impact of exercise may also have value for the veteran population. Furthermore, the current risk of bias assessments highlights the need for additional high-quality RCTs evaluating the specific impact of exercise on PTSD symptom reduction in veterans. In particular, this field of inquiry would benefit from larger samples and design characteristics to reduce bias (eg, blinding when possible, use of CAPS vs only self-report symptom measures, reducing problematic attrition, corrections for missing data, etc).

Trichotillomania is a chronic psychiatric disorder that causes people to repeatedly pull out their own hair. Not only does it result in alopecia with no other underlying causes but it can have significant psychosocial ramifications and rare, but serious, complications. Though the reported prevalence rates are up to approximately 2%, it’s probable that you’ll come upon a patient suffering with this disorder at your practice, if you haven’t already.

To find out more about the best methods for diagnosing and treating this disorder, we spoke with Jon E. Grant, JD, MD, MPH, a leading trichotillomania researcher and part of the department of psychiatry and behavioral neuroscience at the University of Chicago.

Defining trichotillomania

What were the earliest descriptions of trichotillomania in medical literature?

The first real discussion of it probably goes back to Hippocrates, but from a modern medical perspective, discussion began in the 19th century with reports from the French dermatologist François Hallopeau.

They didn’t really call them disorders then – it was long before the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) – but they described this in young men who kept pulling their hair for unclear reasons. These early case reports don’t provide a lot of psychological perspective, but they seem consistent with what we see now.

What are the diagnostic criteria for trichotillomania?

The current DSM-5 criteria are recurrent pulling out of hair, an inability to stop it, the pulling resulting in some noticeable thinning or hair loss, and that it causes some level of distress or some type of impairment in functioning.

At what age do most people experience an onset of symptoms?

Generally speaking, it’s in early adolescence, post puberty, around 12-15 years of age. Having said that, we do see children as young as 1-2 years who are pulling their hair, and we occasionally see somebody far older who is doing it for the first time, a sort of geriatric onset.
 

Overlap and differences with other disorders

You’ve written that although trichotillomania is grouped with obsessive-compulsive disorder (OCD) in the DSM-5, the thinking around that has recently shifted. Why is that?

At first, it was noticed that many of these people pulled their hair repetitively in an almost ritualized manner, perhaps every night before bed. That looked like a compulsion of OCD.

When DSM-5 came out in 2013, they grouped it with OCD. Yet people shifted to thinking that it’s kind of a cousin of OCD because it has this compulsive quality but doesn’t really have obsessive thinking that drives it. Many people just pull their hair. They’re not even always aware of it: sometimes yes, sometimes no.

We know that it has some links to OCD. You’ll see more OCD in folks with trichotillomania, but it clearly is not just the same as OCD. One of the biggest pieces of evidence for that is that our first-line treatment for OCD – a selective serotonin reuptake inhibitor antidepressant – does not really help hair pulling.

Having said that, if people are looking for help with trichotillomania, they often are best served by therapists and doctors who have a familiarity with OCD and have kept it on their radar over the past couple of decades.

How does trichotillomania overlap with skin picking disorder, which is another condition that you’ve closely researched?

It does have some overlap with skin picking in the sense that it often seems familial. For example, the mother may pull her hair and child picks their skin.

It also has a fair amount of comorbidity with skin picking. Many people who pull will pick a little bit or did at some point. Many people who pick pulled their hair at some point. It seems closely related to nail biting as well.

Studies have also shown that one of the things that runs in the histories of most families of people with trichotillomania might be substance abuse – alcohol or drug addiction.

All of this has led people to believe that there might be subtypes of trichotillomania: one that’s more like an OCD and one that’s more like an addiction. That’s similar to the debate with other mental health conditions, that there are probably multiple types of depression, multiple types of schizophrenia.

Is there a component of this that could be defined as self-harm?

That’s been its own debate. It doesn’t seem to have the same developmental trajectory that we see with self-harm, or even some of the personality features.

However, there may be a small segment of folks with trichotillomania that might more appropriately fit that category. For example, those with family histories of trauma, higher rates of posttraumatic stress disorder, or borderline personality. But it wouldn’t be the majority.

The problem is, if you look at some of the pediatrician data, they often group picking, pulling, and cutting. I think that’s far too all-inclusive.
 

A gap in clinician education

Are adolescent patients likely to self-report this behavior, or is it something that physicians need to suss out for themselves?

Clearly, if child psychologists, psychiatrists, or pediatricians see young people with patches of alopecia – eyebrows or eyelashes missing, head hair with spots – in addition to a dermatologic assessment, they should simply ask, “Do you pull your hair?”

But it’s interesting that with the internet, young people are much more likely to disclose and actually come forward and tell their parents that they think they have trichotillomania.

I also hear from a lot of the adolescents that they have to educate their doctors about trichotillomania because so often physicians don’t know much about it and will assume that it’s self-injury or just a symptom of anxiety. It’s a little bit of a flip from what we might have seen 20 years ago.

I’ve seen several patients who’ve said, basically, “I’m tired of no professionals seeming to know about this. I shouldn’t have to be educating my doctors about this.” I tell them that I completely agree. It’s a shame because if a doctor doesn’t know about it, then how can they get the appropriate care?

What are the complications that accompany trichotillomania?

A small percentage, maybe about 10%, will ingest their hair, much like people who bite and swallow their fingernails. The concern there is that because hair is nondigestible, it could create an intestinal plug that could rupture and be potentially life-threatening. That makes it all the more important to ask those who pull their hair what they do with the hair once they pull it.

However, with most people, the real problem is with self-esteem. Young people may not want to socialize, go on dates, or do other things they would normally do because of it. In adults, you may find that they’re far more educated than their job allows but don’t want to go to an interview because they don’t want to have somebody sit there and look at them and notice that perhaps they don’t have any eyebrows, or that they’re wearing a wig. Those psychosocial implications are huge for so many people.
 

Treatment options

In a 2021 study, you showed that nearly one-quarter of people with trichotillomania do naturally recover from it. What characteristics do they seem to have?

It’s interesting because we see natural recovery across many mental health problems: alcohol addition, gambling, OCD. The question then becomes why is that some people can seemingly just stop doing a behavior? Can we learn from those people?

We did see that those who naturally recovered were less likely to have some other mental health comorbidities. It seems like when you have other things such as skin picking or OCD plus trichotillomania, that it probably speaks to something that perhaps synergistically is keeping it going. But this is just a first study; learning how to harness and understand it is the next step.

What’s the goal of treating trichotillomania?

The desired goal is zero pulling. The realistic goal is more likely significantly reduced pulling that then leads to greater function in life, greater quality-of-life.

One doesn’t have to go from 100 to 0 in order to do that. I always tell people that maybe every now and then, every few months, when something is going on in life, you might find yourself pulling a hair or two. That’s okay. If you’re not pulling every day and it’s significantly reduced, we’ll call that a success. I think that setting reasonable goals at this point is really important.

And what would the treatment pathway look like for most patients?

The standard approach is probably some type of habit-reversal therapy, of which there have been many variants over the years. It involves doing something different with your hand, identifying the triggers that may set you off, and then doing something in response to those triggers that is not pulling and might neutralize whatever that anxious or stressed feeling is. That could be different with each person.

At this point, there is no drug approved by the U.S. Food and Drug Administration for trichotillomania. Our best approaches have included N-acetylcysteine, a glutamate modulator, which we’ve done research in.

That’s kind of a go-to option for people because its side-effect profile is generally innocuous. The data show that it could be beneficial in many people with very few, if any, side effects. That would be one “medication,” although it’s actually an over-the-counter vitamin. But we’re constantly looking for better and better treatments.

Do you have any final advice for clinicians or researchers?

Given how common it is, I don’t think clinicians should just see it as an innocuous little habit that people should be able to stop on their own. Clinicians should educate themselves about trichotillomania and know where the person should get the appropriate care.

From the research perspective, given the fact that we see this in animals of multiple species – that they overgroom – this seems to be deeply ingrained in us as animals. So when it comes to the underlying neuroscience, people should pay more attention because it probably has a lot to do with our understanding of habit and compulsive behaviors. It arguably can cut across a lot of different behaviors.

They didn’t really call them disorders then – it was long before the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) – but they described this in young men who kept pulling their hair for unclear reasons. These early case reports don’t provide a lot of psychological perspective, but they seem consistent with what we see now.

What are the diagnostic criteria for trichotillomania?

The current DSM-5 criteria are recurrent pulling out of hair, an inability to stop it, the pulling resulting in some noticeable thinning or hair loss, and that it causes some level of distress or some type of impairment in functioning.

At what age do most people experience an onset of symptoms?

Generally speaking, it’s in early adolescence, post puberty, around 12-15 years of age. Having said that, we do see children as young as 1-2 years who are pulling their hair, and we occasionally see somebody far older who is doing it for the first time, a sort of geriatric onset.
 

Overlap and differences with other disorders

You’ve written that although trichotillomania is grouped with obsessive-compulsive disorder (OCD) in the DSM-5, the thinking around that has recently shifted. Why is that?

At first, it was noticed that many of these people pulled their hair repetitively in an almost ritualized manner, perhaps every night before bed. That looked like a compulsion of OCD.

When DSM-5 came out in 2013, they grouped it with OCD. Yet people shifted to thinking that it’s kind of a cousin of OCD because it has this compulsive quality but doesn’t really have obsessive thinking that drives it. Many people just pull their hair. They’re not even always aware of it: sometimes yes, sometimes no.

We know that it has some links to OCD. You’ll see more OCD in folks with trichotillomania, but it clearly is not just the same as OCD. One of the biggest pieces of evidence for that is that our first-line treatment for OCD – a selective serotonin reuptake inhibitor antidepressant – does not really help hair pulling.

Having said that, if people are looking for help with trichotillomania, they often are best served by therapists and doctors who have a familiarity with OCD and have kept it on their radar over the past couple of decades.

How does trichotillomania overlap with skin picking disorder, which is another condition that you’ve closely researched?

It does have some overlap with skin picking in the sense that it often seems familial. For example, the mother may pull her hair and child picks their skin.

It also has a fair amount of comorbidity with skin picking. Many people who pull will pick a little bit or did at some point. Many people who pick pulled their hair at some point. It seems closely related to nail biting as well.

Studies have also shown that one of the things that runs in the histories of most families of people with trichotillomania might be substance abuse – alcohol or drug addiction.

All of this has led people to believe that there might be subtypes of trichotillomania: one that’s more like an OCD and one that’s more like an addiction. That’s similar to the debate with other mental health conditions, that there are probably multiple types of depression, multiple types of schizophrenia.

Is there a component of this that could be defined as self-harm?

That’s been its own debate. It doesn’t seem to have the same developmental trajectory that we see with self-harm, or even some of the personality features.

However, there may be a small segment of folks with trichotillomania that might more appropriately fit that category. For example, those with family histories of trauma, higher rates of posttraumatic stress disorder, or borderline personality. But it wouldn’t be the majority.

The problem is, if you look at some of the pediatrician data, they often group picking, pulling, and cutting. I think that’s far too all-inclusive.
 

A gap in clinician education

Are adolescent patients likely to self-report this behavior, or is it something that physicians need to suss out for themselves?

Clearly, if child psychologists, psychiatrists, or pediatricians see young people with patches of alopecia – eyebrows or eyelashes missing, head hair with spots – in addition to a dermatologic assessment, they should simply ask, “Do you pull your hair?”

But it’s interesting that with the internet, young people are much more likely to disclose and actually come forward and tell their parents that they think they have trichotillomania.

I also hear from a lot of the adolescents that they have to educate their doctors about trichotillomania because so often physicians don’t know much about it and will assume that it’s self-injury or just a symptom of anxiety. It’s a little bit of a flip from what we might have seen 20 years ago.

I’ve seen several patients who’ve said, basically, “I’m tired of no professionals seeming to know about this. I shouldn’t have to be educating my doctors about this.” I tell them that I completely agree. It’s a shame because if a doctor doesn’t know about it, then how can they get the appropriate care?

What are the complications that accompany trichotillomania?

A small percentage, maybe about 10%, will ingest their hair, much like people who bite and swallow their fingernails. The concern there is that because hair is nondigestible, it could create an intestinal plug that could rupture and be potentially life-threatening. That makes it all the more important to ask those who pull their hair what they do with the hair once they pull it.

However, with most people, the real problem is with self-esteem. Young people may not want to socialize, go on dates, or do other things they would normally do because of it. In adults, you may find that they’re far more educated than their job allows but don’t want to go to an interview because they don’t want to have somebody sit there and look at them and notice that perhaps they don’t have any eyebrows, or that they’re wearing a wig. Those psychosocial implications are huge for so many people.
 

Treatment options

In a 2021 study, you showed that nearly one-quarter of people with trichotillomania do naturally recover from it. What characteristics do they seem to have?

It’s interesting because we see natural recovery across many mental health problems: alcohol addition, gambling, OCD. The question then becomes why is that some people can seemingly just stop doing a behavior? Can we learn from those people?

We did see that those who naturally recovered were less likely to have some other mental health comorbidities. It seems like when you have other things such as skin picking or OCD plus trichotillomania, that it probably speaks to something that perhaps synergistically is keeping it going. But this is just a first study; learning how to harness and understand it is the next step.

What’s the goal of treating trichotillomania?

The desired goal is zero pulling. The realistic goal is more likely significantly reduced pulling that then leads to greater function in life, greater quality-of-life.

One doesn’t have to go from 100 to 0 in order to do that. I always tell people that maybe every now and then, every few months, when something is going on in life, you might find yourself pulling a hair or two. That’s okay. If you’re not pulling every day and it’s significantly reduced, we’ll call that a success. I think that setting reasonable goals at this point is really important.

And what would the treatment pathway look like for most patients?

The standard approach is probably some type of habit-reversal therapy, of which there have been many variants over the years. It involves doing something different with your hand, identifying the triggers that may set you off, and then doing something in response to those triggers that is not pulling and might neutralize whatever that anxious or stressed feeling is. That could be different with each person.

At this point, there is no drug approved by the U.S. Food and Drug Administration for trichotillomania. Our best approaches have included N-acetylcysteine, a glutamate modulator, which we’ve done research in.

That’s kind of a go-to option for people because its side-effect profile is generally innocuous. The data show that it could be beneficial in many people with very few, if any, side effects. That would be one “medication,” although it’s actually an over-the-counter vitamin. But we’re constantly looking for better and better treatments.

Do you have any final advice for clinicians or researchers?

Given how common it is, I don’t think clinicians should just see it as an innocuous little habit that people should be able to stop on their own. Clinicians should educate themselves about trichotillomania and know where the person should get the appropriate care.

From the research perspective, given the fact that we see this in animals of multiple species – that they overgroom – this seems to be deeply ingrained in us as animals. So when it comes to the underlying neuroscience, people should pay more attention because it probably has a lot to do with our understanding of habit and compulsive behaviors. It arguably can cut across a lot of different behaviors.

The first comprehensive guidelines to manage pregnant women with anorexia nervosa (AN) have been released.

Pregnant women with AN are at greater risk of poor outcomes, including stillbirth, underweight infant, or pre-term birth, yet there are no clear guidelines on the management of the condition.

“Anorexia in pregnancy has been an overlooked area of clinical care, as many believed only women in remission become pregnant, and it is clear that is not the case,” lead author Megan Galbally, MBBS, PhD, professor and director, Centre of Women’s and Children’s Mental Health at Monash University School of Clinical Sciences, Melbourne, told this news organization.

“There are great opportunities to support women in their mental health and give them and their babies a healthier start to parenthood and life,” said Dr. Galbally.

“For instance, reducing the likelihood of prematurity or low birth weight at birth that can be associated with anorexia in pregnancy has extraordinary benefits for that child for lifelong health and well-being,” she added.

The guidelines were published online in Lancet Psychiatry.
 

Spike in cases

Dr. Galbally noted that during her 20 years of working in perinatal mental health within tertiary maternity services, she only ever saw an occasional pregnant woman with current AN.

In contrast, over the last 3 to 4 years, there has been a “steep increase in women presenting in pregnancy with very low body mass index (BMI) and current anorexia nervosa requiring treatment in pregnancy,” Dr. Galbally said.

Despite the complexity of managing AN in pregnancy, few studies are available to guide care. In a systematic literature review, the researchers identified only eight studies that addressed the management of AN in pregnancy. These studies were case studies or case reports examining narrow aspects of management.

Digging deeper, the researchers conducted a state-of-the-art research review in relevant disciplines and areas of expertise for managing anorexia nervosa in pregnancy. They synthesized their findings into “recommendations and principles” for multidisciplinary care of pregnant women with AN.

The researchers note that AN in pregnancy is associated with increased risks of pregnancy complications and poorer outcomes for infants, and measures such as BMI are less accurate in pregnancy for assessing severity or change in anorexia nervosa.

Anorexia affects pregnancy and neonatal outcomes through low calorie intake, nutritional and vitamin deficiencies, stress, fasting, low body mass, and poor placentation and uteroplacental function.

The authors note that managing AN in pregnancy requires multidisciplinary care that considers the substantial physiological changes for women and requirements for monitoring fetal growth and development.

At a minimum, they recommend monitoring the following:

• Sodium, potassium, magnesium, phosphate, and chloride concentration
• Iron status, vitamin D and bone mineral density, blood sugar concentration (fasting or random), and A1c
• Liver function (including bilirubin, aspartate transaminase, alanine aminotransferase, and gamma-glutamyl transferase) and bone marrow function (including full blood examination, white cell count, neutrophil count, platelets, and hemoglobin)
• Inflammatory markers (C-reactive protein and erythrocyte sedimentation rate)
• Cardiac function (electrocardiogram and echocardiogram)
• Blood pressure and heart rate (lying and standing) and body temperature

“There are considerable risks for women and their unborn child in managing moderate to severe AN in pregnancy,” said Dr. Galbally.

“While we have provided some recommendations, it still requires considerable adaptation to individual presentations and circumstances, and this is best done with a maternity service that manages other high-risk pregnancies such as through maternal-fetal medicine teams,” she said.

“While this area of clinical care can be new to high-risk pregnancy teams, it is clearly important that high-risk pregnancy services and mental health work together to improve care for women with anorexia in pregnancy,” Dr. Galbally added.
 

A nightmare, a dream come true

Reached for comment, Kamryn T. Eddy, PhD, co-director, Eating Disorders Clinical and Research Program, Massachusetts General Hospital, said, “for many with anorexia nervosa, pregnancy realizes their greatest nightmare and dream come true, both at once.”

“The physical demands of pregnancy can be taxing, and for those with anorexia nervosa, closer clinical management makes sense and may help to support patients who are at risk for return to or worsening of symptoms with the increased nutritional needs and weight gain that occur in pregnancy,” Dr. Eddy, associate professor, department of psychiatry, Harvard Medical School, Boston, told this news organization.

“At the same time, the desire to have a child can be a strong motivator for patients to make the changes needed to recover, and for some, the transition to mother can also help in recovery by broadening the range of things that influence their self-worth,” Dr. Eddy added.

This research had no specific funding. Dr. Galbally and Dr. Eddy report no relevant conflicts of interest.

DENVER – An investigational once-daily oral neuroactive steroid is linked to significant improvement in quality of life (QoL) and well-being in patients with major depressive disorder (MDD), new research shows.

In a phase 3 trial that included more than 500 adult patients with MDD, those who received zuranolone for 14 days showed greater improvement at day 15 across numerous QoL outcomes, compared with their counterparts in the placebo group.

In addition, combined analysis of four zuranolone clinical trials showed “mental well-being and functioning improved to near general population norm levels” for the active-treatment group, reported the researchers, led by Anita H. Clayton, MD, chair and professor of psychiatry, University of Virginia, Charlottesville.

“Based on these integrated analyses, the benefit of treatment with zuranolone may extend beyond reduction in depressive symptoms to include potential improvement in quality of life and overall health, as perceived by patients,” they add.

The findings were presented as part of the Anxiety and Depression Association of America Anxiety & Depression conference.
 

First oral formulation

Zuranolone represents the second entry in the new class of neuroactive steroid drugs, which modulate GABA-A receptor activity – but it would be the first to have an oral formulation. Brexanolone, which was approved by the Food and Drug Administration in 2019 for postpartum depression, is administered through continuous IV infusion over 60 hours.

As previously reported by this news organization, zuranolone improved depressive symptoms as early as day 3, achieving the primary endpoint of significantly greater reduction in scores on the 17-item Hamilton Rating Scale for Depression from baseline to day 15 versus placebo (P = .014).

In the new analysis, patient-reported measures of functional health and well-being were assessed in the WATERFALL trial. It included 266 patients with MDD who were treated with zuranolone 50 mg daily for 2 weeks and 268 patients with MDD who were treated with placebo.

The study used the Short Form–36 (SF-36v2), which covers a wide range of patient-reported measures, including physical function, bodily pain, general health, vitality, social function, and “role-emotional” symptoms.

Results showed that although the treatment and placebo groups had similar baseline SF-36v2 scores, those receiving zuranolone reported significantly greater improvements at day 15 in almost all of the assessment’s domains, including physical function (treatment difference, 0.8), general health (1.0), vitality (3.1), social functioning (1.1), and role-emotional symptoms (1.5; for all comparisons, P < .05). The only exceptions were in role-physical symptoms and bodily pain.

In measures that included physical function, bodily pain, and general health, the patients achieved improvements at day 15 that were consistent with normal levels, with the improvement in vitality considered clinically meaningful versus placebo.

Integrated data

In further analysis of integrated data from four zuranolone clinical trials in the NEST and LANDSCAPE programs for patients with MDD and postpartum depression, results showed similar improvements at day 15 for zuranolone in QoL and overall health across all of the SF-36v2 functioning and well-being domains (P <.05), with the exceptions of physical measure and bodily pain.

By day 42, all of the domains showed significantly greater improvement with zuranolone versus placebo (all, P <.05).

Among the strongest score improvements in the integrated trials were measures in social functioning, which improved from baseline scores of 29.66 to 42.82 on day 15 and to 43.59 on day 42.

Emotional domain scores improved from 24.43 at baseline to 39.13 on day 15 and to 39.82 on day 42. For mental health, the integrated scores for the zuranolone group improved from 27.13 at baseline to 42.40 on day 15 and 42.62 on day 42.

Of note, the baseline scores for mental health represented just 54.3% of those in the normal population; with the increase at day 15, the level was 84.8% of the normal population.

“Across four completed placebo-controlled NEST and LANDSCAPE clinical trials, patient reports of functional health and well-being as assessed by the SF-36v2 indicated substantial impairment at baseline compared to the population norm,” the researchers reported.

The improvements are especially important in light of the fact that in some patients with MDD, functional improvement is a top priority.

“Patients have often prioritized returning to their usual level of functioning over reduction in depressive symptoms, and functional recovery has been associated with better prognosis of depression,” the investigators wrote.

Zuranolone trials have shown that treatment-emergent adverse events (AEs) occur among about 60% of patients, versus about 44% with placebo. The most common AEs are somnolence, dizziness, headache, sedation, and diarrhea, with no increases in suicidal ideation or withdrawal.

The rates of severe AEs are low, and they are observed in about 3% of patients, versus 1.1% with placebo, the researchers noted.

Further, as opposed to serotonergic antidepressants such as SNRIs and SSRIs, zuranolone does not appear to have the undesirable side effects of decreased libido and sexual dysfunction, they added.
 

Clinically meaningful?

Andrew J. Cutler, MD, clinical associate professor of psychiatry at State University of New York, Syracuse, said the data are “very significant” for a number of reasons.

“We need more options to treat depression, especially ones with novel mechanisms of action and faster onset of efficacy, such as zuranolone,” said Dr. Cutler, who was not involved in the current study. He has coauthored other studies on zuranolone.

Regarding the study’s QoL outcomes, “while improvement in depressive symptoms is very important, what really matters to patients is improvement in function and quality of life,” Dr. Cutler noted.

Also commenting on the study, Jonathan E. Alpert, MD, PhD, chair of the department of psychiatry and behavioral sciences and professor of psychiatry, neuroscience, and pediatrics at Albert Einstein College of Medicine, New York, said the investigational drug could represent an important addition to the armamentarium for treating depression.

“Zuranolone has good oral bioavailability and would represent the first neuroactive steroid antidepressant available in oral form and, indeed, the first non–monoamine-based antidepressant available in oral form,” he said in an interview.

Dr. Alpert was not involved in the research and has no relationship with the drug’s development.

He noted that although there are modest differences between the patients who received zuranolone and those who received placebo in the trials, “this may have been related to high placebo response rates, which often complicate antidepressant trials.

“Further research is needed to determine whether differences between zuranolone and placebo are clinically meaningful, though the separation between drug and placebo on the primary endpoint, as well as some other measures, such as quality of life measures, is promising,” Dr. Alpert said.

However, he added that comparisons with other active antidepressants in terms of efficacy and tolerability remain to be seen.

“Given the large number of individuals with major depressive disorder who have incomplete response to or do not tolerate monoaminergic antidepressants, the development of agents that leverage novel nonmonoaminergic mechanisms is important,” Dr. Alpert concluded.

The study was funded by Sage Therapeutics and Biogen. Dr. Cutler has been involved in research of zuranolone for Sage Therapeutics. Dr. Alpert has reported no relevant financial relationships.

The improvements are especially important in light of the fact that in some patients with MDD, functional improvement is a top priority.

“Patients have often prioritized returning to their usual level of functioning over reduction in depressive symptoms, and functional recovery has been associated with better prognosis of depression,” the investigators wrote.

Zuranolone trials have shown that treatment-emergent adverse events (AEs) occur among about 60% of patients, versus about 44% with placebo. The most common AEs are somnolence, dizziness, headache, sedation, and diarrhea, with no increases in suicidal ideation or withdrawal.

The rates of severe AEs are low, and they are observed in about 3% of patients, versus 1.1% with placebo, the researchers noted.

Further, as opposed to serotonergic antidepressants such as SNRIs and SSRIs, zuranolone does not appear to have the undesirable side effects of decreased libido and sexual dysfunction, they added.
 

Clinically meaningful?

Andrew J. Cutler, MD, clinical associate professor of psychiatry at State University of New York, Syracuse, said the data are “very significant” for a number of reasons.

“We need more options to treat depression, especially ones with novel mechanisms of action and faster onset of efficacy, such as zuranolone,” said Dr. Cutler, who was not involved in the current study. He has coauthored other studies on zuranolone.

Regarding the study’s QoL outcomes, “while improvement in depressive symptoms is very important, what really matters to patients is improvement in function and quality of life,” Dr. Cutler noted.

Also commenting on the study, Jonathan E. Alpert, MD, PhD, chair of the department of psychiatry and behavioral sciences and professor of psychiatry, neuroscience, and pediatrics at Albert Einstein College of Medicine, New York, said the investigational drug could represent an important addition to the armamentarium for treating depression.

“Zuranolone has good oral bioavailability and would represent the first neuroactive steroid antidepressant available in oral form and, indeed, the first non–monoamine-based antidepressant available in oral form,” he said in an interview.

Dr. Alpert was not involved in the research and has no relationship with the drug’s development.

He noted that although there are modest differences between the patients who received zuranolone and those who received placebo in the trials, “this may have been related to high placebo response rates, which often complicate antidepressant trials.

“Further research is needed to determine whether differences between zuranolone and placebo are clinically meaningful, though the separation between drug and placebo on the primary endpoint, as well as some other measures, such as quality of life measures, is promising,” Dr. Alpert said.

However, he added that comparisons with other active antidepressants in terms of efficacy and tolerability remain to be seen.

“Given the large number of individuals with major depressive disorder who have incomplete response to or do not tolerate monoaminergic antidepressants, the development of agents that leverage novel nonmonoaminergic mechanisms is important,” Dr. Alpert concluded.

The study was funded by Sage Therapeutics and Biogen. Dr. Cutler has been involved in research of zuranolone for Sage Therapeutics. Dr. Alpert has reported no relevant financial relationships.

DENVER – An investigational once-daily oral neuroactive steroid is linked to significant improvement in quality of life (QoL) and well-being in patients with major depressive disorder (MDD), new research shows.

In a phase 3 trial that included more than 500 adult patients with MDD, those who received zuranolone for 14 days showed greater improvement at day 15 across numerous QoL outcomes, compared with their counterparts in the placebo group.

In addition, combined analysis of four zuranolone clinical trials showed “mental well-being and functioning improved to near general population norm levels” for the active-treatment group, reported the researchers, led by Anita H. Clayton, MD, chair and professor of psychiatry, University of Virginia, Charlottesville.

“Based on these integrated analyses, the benefit of treatment with zuranolone may extend beyond reduction in depressive symptoms to include potential improvement in quality of life and overall health, as perceived by patients,” they add.

The findings were presented as part of the Anxiety and Depression Association of America Anxiety & Depression conference.
 

First oral formulation

Zuranolone represents the second entry in the new class of neuroactive steroid drugs, which modulate GABA-A receptor activity – but it would be the first to have an oral formulation. Brexanolone, which was approved by the Food and Drug Administration in 2019 for postpartum depression, is administered through continuous IV infusion over 60 hours.

As previously reported by this news organization, zuranolone improved depressive symptoms as early as day 3, achieving the primary endpoint of significantly greater reduction in scores on the 17-item Hamilton Rating Scale for Depression from baseline to day 15 versus placebo (P = .014).

In the new analysis, patient-reported measures of functional health and well-being were assessed in the WATERFALL trial. It included 266 patients with MDD who were treated with zuranolone 50 mg daily for 2 weeks and 268 patients with MDD who were treated with placebo.

The study used the Short Form–36 (SF-36v2), which covers a wide range of patient-reported measures, including physical function, bodily pain, general health, vitality, social function, and “role-emotional” symptoms.

Results showed that although the treatment and placebo groups had similar baseline SF-36v2 scores, those receiving zuranolone reported significantly greater improvements at day 15 in almost all of the assessment’s domains, including physical function (treatment difference, 0.8), general health (1.0), vitality (3.1), social functioning (1.1), and role-emotional symptoms (1.5; for all comparisons, P < .05). The only exceptions were in role-physical symptoms and bodily pain.

In measures that included physical function, bodily pain, and general health, the patients achieved improvements at day 15 that were consistent with normal levels, with the improvement in vitality considered clinically meaningful versus placebo.

Integrated data

In further analysis of integrated data from four zuranolone clinical trials in the NEST and LANDSCAPE programs for patients with MDD and postpartum depression, results showed similar improvements at day 15 for zuranolone in QoL and overall health across all of the SF-36v2 functioning and well-being domains (P <.05), with the exceptions of physical measure and bodily pain.

By day 42, all of the domains showed significantly greater improvement with zuranolone versus placebo (all, P <.05).

Among the strongest score improvements in the integrated trials were measures in social functioning, which improved from baseline scores of 29.66 to 42.82 on day 15 and to 43.59 on day 42.

Emotional domain scores improved from 24.43 at baseline to 39.13 on day 15 and to 39.82 on day 42. For mental health, the integrated scores for the zuranolone group improved from 27.13 at baseline to 42.40 on day 15 and 42.62 on day 42.

Of note, the baseline scores for mental health represented just 54.3% of those in the normal population; with the increase at day 15, the level was 84.8% of the normal population.

“Across four completed placebo-controlled NEST and LANDSCAPE clinical trials, patient reports of functional health and well-being as assessed by the SF-36v2 indicated substantial impairment at baseline compared to the population norm,” the researchers reported.

Insomnia rates continue to rise in the setting of the pandemic,¹ contributing to increasing rates of depression and anxiety, as well as worsening symptoms of other severe mental illnesses. Data suggests this symptom, defined as chronic sleep onset and/or sleep continuity problems associated with impaired daytime functioning, is common in psychiatric illnesses, and can worsen their course.²

The incidence of psychiatric illness in patients with insomnia is estimated at near 50%, with the highest rates found in mood disorders such as depression and bipolar disorder, as well as anxiety disorders.³ In patients with diagnosed major depressive disorder, insomnia rates can approach 90%.^4-6

Courtesy Dr. Jennifer Reid

Insomnia has been identified as a risk factor for development of mental illness, including doubling the risk of major depressive disorder and tripling the risk of any depressive or anxiety disorder.^7,8 It can also significantly increase the risk of alcohol abuse and psychosis.⁸

Sleep disturbances can worsen symptoms of diagnosed mental illness, including substance abuse, mood and psychotic disorders.^9-10 In one study, nearly 75% of patients with a diagnosis of schizophrenia or bipolar spectrum disorder had at least one type of sleep disturbance (insomnia, hypersomnia, or delayed sleep phase).¹⁰ This was almost twice the rate in healthy controls. Importantly, compared with well-rested subjects with mental illness in this study, sleep-disordered participants had higher rates of negative and depressive symptoms on the Positive and Negative Syndrome Scale, as well as significantly lower function via the global assessment of functioning.^11,12

Additional data suggests simply being awake during the night (00:00-05:59) elevates risk of suicide. The mean incident rate of completed suicide in one study was a striking four times the rate noted during daytime hours (06:00-23:59 ) (P < .001).¹³

Although insomnia symptoms can resolve after relief from a particular life stressor, as many as half of patients with more severe symptoms develop a chronic course.¹⁴ This then leads to an extended use of many types of sedative-hypnotics designed and studied primarily for short-term use.¹⁵ In a survey reviewing national use of prescription drugs for insomnia, as many as 20% of individuals use a medication to target insomnia in a given month.¹⁶

Fortunately, despite the many challenges posed by COVID-19, particularly for those with psychiatric illness and limited access to care, telehealth has become more readily available. Additionally, digital versions of evidence-based treatments specifically for sleep problems, such as cognitive-behavioral therapy for insomnia (CBT-I), are regularly being developed.

The benefits of CBT-I have been demonstrated repeatedly and it is recommended as the first line treatment for insomnia by the Clinical Guidelines of the American Academy of Sleep Medicine, the Centers for Disease Control and Prevention, and the National Institutes of Health.^17-21 Studies suggest benefits persist long-term, even after completing the therapy sessions, which differ in durability from medication choices.¹⁸

One group that may be particularly suited for treatment with CBT-I is women with insomnia during pregnancy or the postpartum period. In these women, options for treatment may be limited by risk of medication during breastfeeding, as well as difficulty traveling to a physician’s or therapist’s office to receive psychotherapy. However, two recent studies evaluated the use of digital CBT-I to treat insomnia during pregnancy and in the postpartum period, respectively.^22-23

In both studies,the same group of women with insomnia diagnosed during pregnancy were given six weekly 20-minute sessions of digital CBT-I or standard treatment for insomnia, including medication and psychotherapy per their usual provider.

By study end, the pregnant women receiving the CBT-I intervention not only had significantly improved severity of insomnia, they also experienced improved depression and anxiety symptoms, and a decrease in the use of prescription or over-the-counter sleep aides, compared with the standard treatment group, lowering the fetal exposure to medication during pregnancy.²²

In the more recent study, the same group was followed for 6 months post partum.²³ Results were again notable, with the women who received CBT-I reporting significantly less insomnia, as well as significantly lower rates of probable major depression at 3 and 6 months (18% vs. 4%, 10% vs. 0%, respectively.) They also exhibited lower rates of moderate to severe anxiety (17% vs. 4%) at 3 months, compared with those receiving standard care. With as many as one in seven women suffering from postpartum depression, these findings represent a substantial public health benefit.

In summary, insomnia is a critical area of focus for any provider diagnosing and treating psychiatric illness. Attempts to optimize sleep, whether through CBT-I or other psychotherapy approaches, or evidence-based medications dosed for appropriate lengths and at safe doses, should be a part of most, if not all, clinical encounters.

By study end, the pregnant women receiving the CBT-I intervention not only had significantly improved severity of insomnia, they also experienced improved depression and anxiety symptoms, and a decrease in the use of prescription or over-the-counter sleep aides, compared with the standard treatment group, lowering the fetal exposure to medication during pregnancy.²²

In the more recent study, the same group was followed for 6 months post partum.²³ Results were again notable, with the women who received CBT-I reporting significantly less insomnia, as well as significantly lower rates of probable major depression at 3 and 6 months (18% vs. 4%, 10% vs. 0%, respectively.) They also exhibited lower rates of moderate to severe anxiety (17% vs. 4%) at 3 months, compared with those receiving standard care. With as many as one in seven women suffering from postpartum depression, these findings represent a substantial public health benefit.

In summary, insomnia is a critical area of focus for any provider diagnosing and treating psychiatric illness. Attempts to optimize sleep, whether through CBT-I or other psychotherapy approaches, or evidence-based medications dosed for appropriate lengths and at safe doses, should be a part of most, if not all, clinical encounters.

Anxiety and depression are common among individuals with inflammatory bowel disease (IBD) who are in remission, and the conditions are linked to unemployment and presenteeism, according to a prospective study.

Previous studies have found a heightened risk of anxiety and depression in IBD, as well as an association with poor treatment compliance and greater morbidity. Presenteeism, defined as reduced productivity due to a physical or mental condition, is increasingly recognized as an indirect economic cost of chronic conditions that may exact a higher cost than absenteeism.

Atypical anxiety in adults with Parkinson’s disease ranged from 15% to 51% in a systematic review of 60 studies.

Anxiety is common in Parkinson’s disease (PD) and has been shown to increase functional disability and decrease quality of life, but atypical presentations of anxiety are underrecognized and often undertreated in PD patients, wrote Nadeeka N. Dissanayaka, PhD, of the University of Queensland, Brisbane, Australia, and colleagues.

In a study published in the American Journal of Geriatric Psychiatry , the researchers conducted a systematic review of 60 studies to better characterize atypical PD-related anxiety. Fourteen studies involved Anxiety Not Otherwise Specified (NOS), 31 included fluctuating anxiety symptoms, and 22 included Fear of Falling (FOF).

Overall, the average prevalence rate for anxiety disorders in the PD population was 31%.

Anxiety NOS, fluctuating anxiety, and FOF accounted for a weighted mean prevalence of 14.9%, 34.19%, and 51.5%, respectively.

The symptomatology of anxiety NOS included psychological distress about the PD diagnosis, insecurity about the future, fear of losing control of motor and bodily functions, and social embarrassment. Clinically, anxiety NOS was associated with a range of factors including minor depression, on-off motor symptoms, muscle cramps, poor quality of life, and gait impairment.

The symptomatology of fluctuating anxiety was assessed in 9 studies of the “on” motor state and 16 studies of both “on” and “off.” Symptoms associated with the off state included panic attacks, feeling anxious or sad, and avoiding situations, as well as palpitations, dizziness, chills, and hot flashes.

Clinically, studies showed that anxiety was more severe in the off-medication state, and symptoms were reduced in the on state. Data from some studies showed that fluctuating anxiety was more common in PD patients who were female, and who had a younger age of PD onset and longer disease duration.

The symptomatology of FOF included associations between FOF and difficulty with walking and gait: Using a walker or other device, more frequent freezing in place, hesitation when turning, and slower speed while walking. Clinically, characteristics associated with FOF included older age, needing assistance for activities of daily living, a history of falls, and reduced quality of life.

The results of the review were limited by several factors including the varying assessment techniques, and the lack of data on treatment for atypical anxiety in PD, the researchers noted. “To our knowledge there are no treatment trials focused on Anxiety NOS,” and studies on the treatment of fluctuating anxiety and FOF are preliminary, they said.

However, the results support the need for early identification and classification of PD-related anxiety to improve treatment strategies and long-term outcomes, the researchers concluded. In the absence of evidence-based treatment strategies, “Given the heterogeneity of anxiety presentations in PD, the importance of tailoring interventions to meet the specific needs and unique symptom profiles of each individual cannot be overstated,” and routine screening of PD patients for anxiety every 6-12 months is recommended, they emphasized.

Suicidal behaviors are common in older adults – and especially older women, new research suggests.

In a meta-analysis that included 20 studies and more than 3 million total individuals living in long-term care (LTC), the prevalence rate for suicidal behavior was more than 6%. In addition, the most common of these behaviors was suicidal ideation.

The prevalence was much higher in women than in men.

These high rates underline the need for clinicians to exercise “extra caution” when assessing elderly people living in a long-term care facility, coinvestigator Syeda Beenish Bareeqa, MBBS, clinical researcher, Jinnah Medical and Dental College, Karachi, Pakistan, and research observer, University of Texas Southwestern Medical Center, Dallas, said in an interview.

“Missed diagnoses or undertreatment in this population can lead to deleterious health outcomes,” Dr. Bareeqa said.

The findings were presented at the annual meeting of the American Association for Geriatric Psychiatry.
 

Underdiagnosed, undertreated

In the United States, about 42% of adults 70 years and older will live in LTC, either in an assisted care facility or a nursing home, Dr. Bareeqa noted.

Although many LTC residents have a mood disorder, previous research shows that fewer than 25% of cases are diagnosed and treated, she said.

Dr. Bareeqa added that suicide – and its association with factors such as the COVID-19 pandemic, depression, and cyberbullying – is a topic of increasing interest to researchers. She and her colleagues wanted to investigate suicidal behaviors in the setting of LTC.

The researchers conducted a literature search for studies of suicidal behavior among LTC residents over aged 60 years. They examined general suicidal behavior and the most common subtypes: suicide ideation, suicide attempts, completed suicide, self-destructive behavior, and nonsuicidal self-injury.

The analysis included 20 studies and 3 million individuals living in LTC. The majority of the studies were conducted in the United States (n = 5) and Australia (n = 4).

Results showed an estimated suicidal behavior prevalence rate of 6.4% (.064; 95% confidence interval, .057 to .070), or 64 per 100,000 persons.

A rate this high is “alarming and unexpected,” said Dr. Bareeqa. She noted most of the studies included in the analysis were conducted in developed countries with advanced health care systems.

The World Health Organization reports the suicide rate per 100,000 older adults (aged 75 years and older) is 50 for men and 16 for women, but this is not stratified by living settings, Dr. Bareeqa noted.
 

Higher rates in women

In the current analysis, 5 of the 20 studies had low risk of bias, 14 had moderate risk, and 1 had high risk, Dr. Bareeqa reported.

In subgroup analyses, the researchers found much of the suicidal behavior was driven by studies out of Australia, where the prevalence of suicidal behaviors was 36.9% (95% CI, 9.2-64.7) vs. 1.4% in the U.S. (95% CI, 1.0-1.8).

Another surprising finding was the prevalence of suicidal behaviors among women (15.8%), which was much higher than among men (7.9%). “Male gender is a well-established risk factor for suicide in the medical literature but this is not the case in our study,” said Dr. Bareeqa.

In addition, the analysis showed suicidal ideation was the most common type of suicidal behavior. In a pooled population of around 2 million people in eight studies, the prevalence of suicidal ideation was 12%.

For psychiatric illnesses accompanying suicidal behavior, the prevalence of depression alone was 14.4%, which was much higher than the rate of 5.1% for multiple comorbidities – including depression, anxiety, obsessive-compulsive disorder, psychotic disorder, history of previous suicide attempt, delusion, delirium, and hallucination.

Although depression and other psychiatric conditions may help explain suicidal behavior in older adults, Dr. Bareeqa said physical illness also plays a major role.

“Illnesses like cancer or end-stage organ failure, which are quite common with advancing age, are debilitating and in some instances incurable. These medical problems create a breeding ground for mental health problems and can eventually lead to devastating outcomes such as suicide,” she said.

She noted the importance of a “multipronged approach” to prevent suicide among older people in LTC facilities.

In addition, her research team aims to assess the quality of care provided by LTC facilities. “Maybe we can get to the root of this problem and devise strategies to improve it,” she said.
 

‘Not uncommon’

In an interview with this news organization Rajesh R. Tampi, MBBS, professor and chairman, department of psychiatry, Creighton University and Catholic Health Initiatives Health Behavioral Health Services, Omaha, Neb., said the results suggest that, despite the risk for bias among the included studies, “suicidal behaviors are not uncommon among older adults in LTC.”

The analysis describes only associations “but does not indicate causality,” said Dr. Tampi, past president of the AAGP. He was not involved with the research.

Additional subgroup analyses should yield information on possible risk factors for suicidal behaviors in LTC, such as depression, anxiety, and chronic pain, he added.
