Identifying Posttraumatic Stress Disorder and Disparity Among Transgender Veterans Using Nationwide Veterans Health Administration Electronic Health Record Data

Comorbidity Profiles of Posttraumatic Stress Disorder Across the Medical Phenome

Background

Previous epidemiological research has linked posttraumatic stress disorder (PTSD) with specific physical health problems, but the comprehensive landscape of medical conditions associated with PTSD remains uncharacterized. Electronic health records provide an opportunity to overcome clinical knowledge gaps and uncover associations with biological relevance that potentially vary by sex.

Methods

PTSD was defined among biobank participants (N = 145,959) in 3 major healthcare systems using 2 ICD code-based definitions: broad (≥1 PTSD or acute stress codes vs. 0; n cases = 16,706) and narrow (≥2 PTSD codes vs. 0; n cases = 3325). Using a phenome-wide association study design, we tested associations between each PTSD definition and all prevalent disease umbrella categories, i.e., phecodes. We also conducted sex-stratified phenome-wide association study analyses including a sex × diagnosis interaction term in each logistic regression.

Results

A substantial number of phecodes were significantly associated with PTSDNarrow (61%) and PTSDBroad (83%). While the strongest associations were shared between the 2 definitions, PTSDBroad captured 334 additional phecodes not significantly associated with PTSDNarrow and exhibited a wider range of significantly associated phecodes across various categories, including respiratory, genitourinary, and circulatory conditions. Sex differences were observed in that PTSDBroad was more strongly associated with osteoporosis, respiratory failure, hemorrhage, and pulmonary heart disease among male patients and with urinary tract infection, acute pharyngitis, respiratory infections, and overweight among female patients.

Conclusions

This study provides valuable insights into a diverse range of comorbidities associated with PTSD, including both known and novel associations, while highlighting the influence of sex differences and the impact of defining PTSD using electronic health records.

The Associations Between Gender Minority Stressors and PTSD Symptom Severity Among Trauma-Exposed Transgender and Gender Diverse Adults

This study investigates associations between minority stressors, traumatic stressors, and post-traumatic stress disorder (PTSD) symptom severity in a sample of transgender and gender diverse (TGD) adults. We utilized surveys and clinical interview assessments to assess gender minority stress exposures and responses, and PTSD. Our sample (N = 43) includes adults who identified as a minoritized gender identity (i.e., 39.5% trans woman or woman, 25.6% trans man or man, 23.3% genderqueer or nonbinary, 11.6% other identity). All participants reported at least one traumatic event (i.e., life threat, serious injury, or sexual harm). The most common trauma events reported by the sample were sexual (39.5%) and physical violence (37.2%), with 40.9% of participants anchoring their symptoms to a discrimination-based event. PTSD symptom severity was positively correlated with both distal (r = 0.36, p = .017) and proximal minority stressors (r = 0.40, p < .01). Distal minority stress was a unique predictor of current PTSD symptom severity (b = 0.94, p = .017), however, this association was no longer significant when adjusting for proximal minority stress (b = 0.18, p = 0.046). This study suggests that minority stress, especially proximal minority stress, is associated with higher PTSD symptom severity among TGD adults.

Stressful life events in electronic health records: a scoping review

OBJECTIVES

Stressful life events, such as going through divorce, can have an important impact on human health. However, there are challenges in capturing these events in electronic health records (EHR). We conducted a scoping review aimed to answer 2 major questions: how stressful life events are documented in EHR and how they are utilized in research and clinical care.

MATERIALS AND METHODS

Three online databases (EBSCOhost platform, PubMed, and Scopus) were searched to identify papers that included information on stressful life events in EHR; paper titles and abstracts were reviewed for relevance by 2 independent reviewers.

RESULTS

Five hundred fifty-seven unique papers were retrieved, and of these 70 were eligible for data extraction. Most articles (n = 36, 51.4%) were focused on the statistical association between one or several stressful life events and health outcomes, followed by clinical utility (n = 15, 21.4%), extraction of events from free-text notes (n = 12, 17.1%), discussing privacy and other issues of storing life events (n = 5, 7.1%), and new EHR features related to life events (n = 4, 5.7%). The most frequently mentioned stressful life events in the publications were child abuse/neglect, arrest/legal issues, and divorce/relationship breakup. Almost half of the papers (n = 7, 46.7%) that analyzed clinical utility of stressful events were focused on decision support systems for child abuse, while others (n = 7, 46.7%) were discussing interventions related to social determinants of health in general.

DISCUSSION AND CONCLUSIONS

Few citations are available on the prevalence and use of stressful life events in EHR reflecting challenges in screening and storing of stressful life events.

A Systematic Review of the Effect of PTSD and Trauma on Treatment Outcomes for Eating Disorders

There is growing evidence of prior experiences of trauma and trauma-related symptoms among people with eating disorders; however, there is little understanding as to how post-traumatic stress disorder (PTSD) and exposure to traumatic events affect treatment outcomes. Without this knowledge, eating disorder clinicians are unable to tailor treatment to ensure good outcomes for the large percentage of this population that is affected by PTSD and trauma. This systematic review aimed to identify how PTSD and trauma exposure influence outcomes in eating disorder treatment. Systematic searches of PsycINFO, MEDLINE, PubMed, and Scopus databases identified 16 articles that met the inclusion criteria. The results indicated a negative effect on rates of eating disorder treatment completion and eating disorder psychopathology posttreatment. These findings were evident across studies that investigated the impact of a history of traumatic events as well as studies that investigated the impact of the presence of trauma-related symptoms seen in PTSD. Several methodological limitations were identified in the literature. These include: heterogeneous and unstandardized measures of PTSD and trauma, high attrition rates with follow-up, and insufficient data to enable comparisons by treatment setting, diagnostic presentation, and type of trauma exposure. The findings of this review have implications for future research and clinical care, including the importance of considering PTSD and trauma in assessment, treatment planning, and provision of both trauma-informed care and trauma-focused treatments for individuals with eating disorders.

Risk of Suicide and Self-Harm Following Gender-Affirmation Surgery

Introduction With the growing acceptance of transgender individuals, the number of gender affirmation surgeries has increased. Transgender individuals face elevated depression rates, leading to an increase in suicide ideation and attempts. This study evaluates the risk of suicide or self-harm associated with gender affirmation procedures. Methods This retrospective study utilized de-identified patient data from the TriNetX (TriNetX, LLC, Cambridge, MA) database, involving 56 United States healthcare organizations and over 90 million patients. The study involved four cohorts: cohort A, adults aged 18-60 who had gender-affirming surgery and an emergency visit (N = 1,501); cohort B, control group of adults with emergency visits but no gender-affirming surgery (N = 15,608,363); and cohort C, control group of adults with emergency visits, tubal ligation or vasectomy, but no gender-affirming surgery (N = 142,093). Propensity matching was applied to cohorts A and C. Data from February 4, 2003, to February 4, 2023, were analyzed to examine suicide attempts, death, self-harm, and post-traumatic stress disorder (PTSD) within five years of the index event. A secondary analysis involving a control group with pharyngitis, referred to as cohort D, was conducted to validate the results from cohort C. Results Individuals who underwent gender-affirming surgery had a 12.12-fold higher suicide attempt risk than those who did not (3.47% vs. 0.29%, RR 95% CI 9.20-15.96, p < 0.0001). Compared to the tubal ligation/vasectomy controls, the risk was 5.03-fold higher before propensity matching and remained significant at 4.71-fold after matching (3.50% vs. 0.74%, RR 95% CI 2.46-9.024, p < 0.0001) for the gender affirmation patients with similar results with the pharyngitis controls. Conclusion Gender-affirming surgery is significantly associated with elevated suicide attempt risks, underlining the necessity for comprehensive post-procedure psychiatric support.

Effects of sex and gender on the etiologies and presentation of select internalizing psychopathologies

The internalizing spectrum encompasses a subset of psychopathologies characterized by emotional liability, anhedonia, anxiousness, distress, and fear, and includes, among others, diagnoses of major depressive disorder (MDD), generalized anxiety disorder (GAD), and posttraumatic stress disorder (PTSD). In this review, we describe the vast body of work highlighting a role for sex and gender in the environment, symptom onset, genetic liability, and disorder progression and comorbidities of MDD, GAD, and PTSD. We also point the reader to different language used in diverse fields to describe sexual and gender minorities that may complicate the interpretation of emerging literature from the social sciences, psychiatric and psychological sciences, and genetics. Finally, we identify several gaps in knowledge that we hope serve as launch-points for expanding the scope of psychiatric studies beyond binarized sex-stratification. Despite being under-represented in genomics studies, placing emphasis on inclusion of sexual and gender diverse participants in these works will hopefully improve our understanding of disorder etiology using genetics as one tool to inform how biology (e.g., hormone concentration) and environmental variables (e.g., exposure to traumatic events) contribute to differences in symptom onset, pattern, and long-term trajectory.

Implementation of LGBTQ+ affirming care policies in the Veterans Health Administration: preliminary findings on barriers and facilitators in the southern United States

Background

In the United States Department of Veterans Affairs (VA), veterans who are lesbian, gay, bisexual, transgender, queer, and similar gender and sexual minoritized people (LGBTQ+) experience health disparities compared to cisgender, heterosexual veterans. VA's LGBTQ+ Health Program created two healthcare policies on providing LGBTQ+ affirming care (healthcare that is inclusive, validating, and understanding of the LGBTQ+ population). The current project examines providers' barriers and facilitators to providing LGBTQ+ affirming care and LGBTQ+ veterans' barriers and facilitators to receiving LGBTQ+ affirming care.

Methods

Data collection and analysis were informed by the Consolidated Framework for Implementation Research, which was adapted to include three health equity domains. Data collection involved telephone interviews conducted with 11 VA providers and 12 LGBTQ+ veterans at one rural and one urban VA medical center, and one rural VA community clinic. Qualitative data were rapidly analyzed using template analysis, a data reduction technique.

Results

Providers described limited education, limited time, lack of experience with the population, and a lack of awareness of resources as barriers. Providers discussed comfort with consulting trusted peers, interest in learning more about providing LGBTQ+ affirming care, and openness and acceptance of the LGBTQ+ community as facilitators. LGBTQ+ veterans described a lack of provider awareness of their needs, concerns related to safety and discrimination, and structural discrimination as barriers. LGBTQ+ veterans described positive relationships with providers, knowledge of their own healthcare needs, and ability to advocate for their healthcare needs as facilitators. Although VA's LGBTQ+ affirming care policies are in place, providers and veterans noted a lack of awareness regarding specific healthcare processes.

Conclusion

Allowing more time and capacity for education and engaging LGBTQ+ veterans in determining how to improve their healthcare may be the path forward to increase adherence to LGBTQ+ affirming care policies. Engaging patients, especially those from marginalized backgrounds, in strategies focused on the uptake of policy may be a path to improve policy implementation. It is possible that creating truly collaborative structures in which patients, staff, providers, leadership, and policymakers can work together towards policy implementation may be a useful strategy. In turn, improved policy implementation would result in increased physical and mental health for LGBTQ+ veterans.

Barriers and Facilitators to Gender-affirming Hormone Therapy in the Veterans Health Administration

BACKGROUND

In 2011, the Veterans Health Administration (VHA) established a policy for the delivery of transition-related services, including gender-affirming hormone therapy (GAHT), for transgender and gender diverse (TGD) patients. In the decade since this policy's implementation, limited research has investigated barriers and facilitators of VHA's provision of this evidence-based therapy that can improve life satisfaction among TGD patients.

PURPOSE

This study provides a qualitative summary of barriers and facilitators to GAHT at the individual (e.g., knowledge, coping mechanisms), interpersonal (e.g., interactions with other individuals or groups), and structural (e.g., gender norms, policies) levels.

METHODS

Transgender and gender diverse patients (n = 30) and VHA healthcare providers (n = 22) completed semi-structured, in-depth interviews in 2019 regarding barriers and facilitators to GAHT access and recommendations for overcoming perceived barriers. Two analysts used content analysis to code and analyze transcribed interview data and employed the Sexual and Gender Minority Health Disparities Research Framework to organize themes into multiple levels.

RESULTS

Facilitators included having GAHT offered through primary care or TGD specialty clinics and knowledgeable providers, with patients adding supportive social networks and self-advocacy. Several barriers were identified, including a lack of providers trained or willing to prescribe GAHT, patient dissatisfaction with prescribing practices, and anticipated or enacted stigma. To overcome barriers, participants recommended increasing provider capacity, providing opportunities for continual education, and enhancing communication around VHA policy and training.

CONCLUSIONS

Multi-level system improvements within and outside the VHA are needed to ensure equitable and efficient access to GAHT.

Nonsuicidal self-injury methods among U.S. Veterans: Latent class analysis and associations with psychosocial outcomes

Nonsuicidal self-injury (NSSI) is a debilitating concern among U.S. veterans, with wall/object-punching commonly endorsed as an NSSI method. We examined how this behavior relates to other NSSI methods and psychosocial outcomes. We conducted a latent class analysis (LCA) of NSSI methods among 1,138 Gulf War Era veterans, (77.9% male), 21.7% of whom endorsed lifetime NSSI. We categorized classes based on their associations with age, sex, combat and military sexual assault exposure, then examined the association of class membership with psychosocial indicators. LCA results supported four classes: 1) High punching/banging NSSI (2.5%); 2) Multimethod NSSI methods (6.3%); 3) High-risk, multimethod NSSI (3.1%); and 4) Low-risk NSSI (88.1%). Psychosocial indicators (suicide attempt, ideation, possible depressive or posttraumatic stress disorders, poor psychosocial functioning) were worse for members of the NSSI classes versus those in the low-risk group. A subset of U.S. veterans may engage in NSSI primarily via punching/banging methods. All patterns of NSSI engagement were associated with negative psychosocial outcomes relative to those in the low-risk class of the behavior.

Recruiting Sexual and Gender Minority Veterans for Health Disparities Research: Recruitment Protocol of a Web-Based Prospective Cohort Study

BACKGROUND

The Health for Every Veteran Study is the first Veterans Health Administration-funded, nationwide study on lesbian, gay, bisexual, transgender, queer, and other sexual and gender minority (LGBTQ+) veterans' health that relies exclusively on primary recruitment methods. This study aimed to recruit 1600 veterans with diverse sexual and gender identities to study the mental health and health risk behaviors of this population. A growing body of literature highlights the health inequities faced by LGBTQ+ veterans when compared with their heterosexual or cisgender peer groups. However, there is little to no guidance in the health disparities literature describing the recruitment of LGBTQ+ veterans.

OBJECTIVE

This paper provides an overview of the recruitment methodology of Health for Every Veteran Study. We describe the demographics of the enrolled cohort, challenges faced during recruitment, and considerations for recruiting LGBTQ+ veterans for health research.

METHODS

Recruitment for this study was conducted for 15 months, from September 2019 to December 2020, with the goal of enrolling 1600 veterans evenly split among 8 sexual orientation and gender identity subgroups: cisgender heterosexual women, cisgender lesbian women, cisgender bisexual women, cisgender heterosexual men, cisgender gay men, cisgender bisexual men, transgender women, and transgender men. Three primary recruitment methods were used: social media advertising predominantly through Facebook ads, outreach to community organizations serving veterans and LGBTQ+ individuals across the United States, and contracting with a research recruitment company, Trialfacts.

RESULTS

Of the 3535 participants screened, 1819 participants met the eligibility criteria, and 1062 completed the baseline survey to enroll. At baseline, 25.24% (268/1062) were recruited from Facebook ads, 40.49% (430/1062) from community outreach, and 34.27% (364/1062) from Trialfacts. Most subgroups neared the target enrollment goals, except for cisgender bisexual men, women, and transgender men. An exploratory group of nonbinary and genderqueer veterans and veterans with diverse gender identities was included in the study.

CONCLUSIONS

All recruitment methods contributed to significant portions of the enrolled cohort, suggesting that a multipronged approach was a critical and successful strategy in our study of LGBTQ+ veterans. We discuss the strengths and challenges of all recruitment methods, including factors impacting recruitment such as the COVID-19 pandemic, negative comments on Facebook ads, congressional budget delays, and high-volume surges of heterosexual participants from community outreach. In addition, our subgroup stratification offers important disaggregated insights into the recruitment of specific LGBTQ+ subgroups. Finally, the web-based methodology offers important perspectives not only for reaching veterans outside of the Veterans Health Administration but also for research studies taking place in the COVID-19-impacted world. Overall, this study outlines useful recruitment methodologies and lessons learned to inform future research that seeks to recruit marginalized communities.

Associations between DSM-5 posttraumatic stress disorder Criterion E2 endorsement and selected self-destructive behaviors in recent-era veterans: A focus on disordered eating

Revisions to the posttraumatic stress disorder (PTSD) criteria in the DSM-5 included a new criterion in the alterations in arousal and reactivity cluster (i.e., engagement in reckless and self-destructive behaviors; Criterion E2). Despite its clinical significance, little is known about how this symptom corresponds to engagement in specific direct and indirect self-harm behaviors. We examined associations between E2 and self-reported recent engagement in direct and indirect self-harm behaviors, including disordered eating, which is not included in the prototypical E2 symptom scope, in a trauma-exposed sample of 1,010 recent-era veterans (61.5% self-identified women, 38.5% self-identified men). We also tested whether gender moderated these associations. We repeated analyses in a subsample of participants with clinically elevated PTSD symptoms. Participants self-reported past-month PTSD symptoms (PCL-5) as well as past-month nonsuicidal self-injury, suicidal ideation, suicide planning, fasting, purging, binge eating, compulsive exercise, and problematic alcohol and drug use. We found no evidence for moderation by gender for any of the behaviors examined in the main sample. However, after controlling for gender and demographic covariates, weighted logistic regressions showed small, significant associations between E2 score and direct self-harm behaviors, substance use, purging, and binge eating, aORs = 1.30-1.91. Criterion E2 was linked to behaviors included in the typical symptom scope (self-directed violence, substance use) and those that are not (disordered eating behaviors). Comprehensive screening for self-destructive behaviors, including disordered eating, among veteran men and women who endorse Criterion E2 is indicated.

Expressive writing treatments to reduce PTSD symptom severity and negative alcohol-related outcomes among trauma-exposed sexual minority women and transgender/nonbinary people: Study protocol for a mixed-method pilot trial

Background

Sexual minority women (SMW) and transgender and/or nonbinary (TNB) individuals report an elevated prevalence of posttraumatic stress disorder (PTSD) symptoms and negative alcohol-related outcomes compared to heterosexual women and cisgender people. SMW and TNB individuals also face barriers to utilizing treatment, which can result in delayed or missed appointments. Accessible, feasible, and effective treatment approaches, such as web-based expressive writing (EW) treatments, are needed to address PTSD and negative alcohol-related outcomes in these populations.

Method

We describe the design of a mixed-method pilot randomized controlled trial which will compare an EW treatment adapted for SMW and TNB people (stigma-adapted EW) and trauma (i.e., non-adapted) EW with an active (neutral-event) control to determine acceptability and feasibility of a future fully powered randomized controlled trial. The sample will include 150 trauma-exposed SMW and TNB individuals from across the United States who will be randomly assigned to stigma-adapted EW (n = 50), trauma EW (n = 50), or control (n = 50). Participants will be assessed before treatment, one-week after the first writing session, and three-months after the first writing session. This paper identifies steps for evaluating the acceptability and feasibility of the proposed study and determining changes in outcomes resulting from adapted and non-adapted EW treatments to inform refinements. This paper also highlights our strategy for testing theory-driven mediators and moderators of treatment outcomes.

Conclusions

This mixed-method pilot trial will inform the first fully powered, self-administered, brief web-based treatment to reduce PTSD symptom severity and negative alcohol-related outcomes among trauma-exposed SMW and TNB individuals.

Trauma Matters: Integrating Genetic and Environmental Components of PTSD

Trauma is ubiquitous, but only a subset of those who experience trauma will develop posttraumatic stress disorder (PTSD). In this review, it is argued that to determine who is at risk of developing PTSD, it is critical to examine the genetic etiology of the disorder and individual trauma profiles of those who are susceptible. First, the state of current PTSD genetic research is described, with a particular focus on studies that present evidence for trauma type specificity, or for differential genetic etiology according to gender or race. Next, approaches that leverage non-traditional phenotyping approaches are reviewed to identify PTSD-associated variants and biology, and the relative advantages and limitations inherent in these studies are reflected on. Finally, it is discussed how trauma might influence the heritability of PTSD, through type, risk factors, genetics, and associations with PTSD symptomology.

Open Trial of Trauma-Focused Psychodynamic Psychotherapy for Posttraumatic Stress Disorder Among LGBTQ Individuals

OBJECTIVE

Lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals report higher rates of exposure to traumatic events and posttraumatic stress disorder (PTSD) compared with heterosexual and cisgender individuals. No treatment outcomes research has focused on PTSD in the LGBTQ population. Trauma-focused psychodynamic psychotherapy (TFPP) is a brief, manualized, attachment- and affect-focused psychotherapy for PTSD. TFPP explicitly incorporates broad identity-related and societal factors into its conceptualization of trauma and its consequences, which may be especially helpful for LGBTQ patients with minority stress who seek affirmative care.

METHODS

Fourteen LGBTQ patients with PTSD, assessed with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), received 24 sessions of twice-weekly (12 weeks) TFPP via teletherapy provided by supervised early-career therapists inexperienced in the modality. Sessions were videotaped to monitor therapists' treatment adherence. Patients were assessed at baseline, week 5, termination (week 12), and 3 months posttreatment for PTSD symptoms (assessed with the CAPS-5) and secondary outcomes.

RESULTS

TFPP was well tolerated by patients, with 12 (86%) completing the intervention. CAPS-5-measured PTSD symptoms, including dissociation, significantly improved during treatment (mean decrease=-21.8, d=-1.98), and treatment gains were maintained at follow-up. Most patients experienced PTSD clinical response (N=10, 71%) or diagnostic remission (N=7, 50%). Patients generally experienced significant, concomitant improvements in complex PTSD symptoms, general anxiety, depression, and psychosocial functioning. Adherence to the intervention among therapists was high, with 93% of rated sessions meeting adherence standards.

CONCLUSIONS

TFPP shows promise in the treatment of PTSD among sexual and gender minority patients seeking LGBTQ-affirmative PTSD care.

Comorbidity Profiles of Posttraumatic Stress Disorder Across the Medical Phenome

Background

Prior epidemiological research has linked PTSD with specific physical health problems, but the comprehensive landscape of medical conditions associated with PTSD remains uncharacterized. Electronic health records (EHR) provide an opportunity to overcome prior clinical knowledge gaps and uncover associations with biological relevance that potentially vary by sex.

Methods

PTSD was defined among biobank participants (total N=123,365) in a major healthcare system using two ICD code-based definitions: broad (1+ PTSD or acute stress codes versus 0; NCase=14,899) and narrow (2+ PTSD codes versus 0; NCase=3,026). Using a phenome-wide association (PheWAS) design, we tested associations between each PTSD definition and all prevalent disease umbrella categories, i.e., phecodes. We also conducted sex-stratified PheWAS analyses including a sex-by-diagnosis interaction term in each logistic regression.

Results

A substantial number of phecodes were significantly associated with PTSDNarrow (61%) and PTSDBroad (83%). While top associations were shared between the two definitions, PTSDBroad captured 334 additional phecodes not significantly associated with PTSDNarrow and exhibited a wider range of significantly associated phecodes across various categories, including respiratory, genitourinary, and circulatory conditions. Sex differences were observed, in that PTSDBroad was more strongly associated with osteoporosis, respiratory failure, hemorrhage, and pulmonary heart disease among male patients, and with urinary tract infection, acute pharyngitis, respiratory infections, and overweight among female patients.

Conclusions

This study provides valuable insights into a diverse range of comorbidities associated with PTSD, including both known and novel associations, while highlighting the influence of sex differences and the impact of defining PTSD using EHR.

Compensation and Pension Exams for Military Sexual Trauma-Related Posttraumatic Stress Disorder: Examiner Perspectives, Clinical Impacts on Veterans, and Strategies

BACKGROUND

It is estimated that in one in three women veterans experience military sexual trauma (MST), which is strongly associated with posttraumatic stress disorder (PTSD). A 2018 report indicated the Veterans Benefits Administration (VBA) processed approximately 12,000 disability claims annually for PTSD related to MST, most of which are filed by women. Part of the VBA adjudication process involves reviewing information from a Compensation and Pension (C&P) exam, a forensic diagnostic evaluation that helps determine the relationship among military service, diagnoses, and current psychosocial functioning. The quality and outcome of these exams may affect veteran well-being and use of Veterans Health Administration (VHA) mental health care, but no work has looked at examiner perspectives of MST C&P exams and their potential clinical impacts on veteran claimants.

METHODS

Thirteen clinicians ("examiners") who conduct MST C&P exams through VHA were interviewed. Data were analyzed using rapid qualitative methods.

RESULTS

Examiners described MST exams as more clinically and diagnostically complex than non-MST PTSD exams. Examiners noted that assessing "markers" of MST (indication that MST occurred) could make veterans feel disbelieved; others raised concerns related to malingered PTSD symptoms. Examiners identified unique challenges for veterans who underreport MST (e.g., men and lesbian, gay, bisexual, transgender, and queer [LGBTQ+] veterans), and saw evaluations as a conduit to psychotherapy referrals and utilization of VHA mental health care. Last, examiners used strategies to convey respect and minimize retraumatization, including a standardized process and validating the difficulty of the process.

CONCLUSIONS

Examiners' responses offer insight into a process entered by thousands of veterans annually with PTSD. Strengthening the MST C&P process is a unique opportunity to enhance trust in the VBA claims process and increase likelihood of using VHA mental health care, especially for women veterans.

Probable PTSD, PTSD symptom severity, and comorbid PTSD and hazardous drinking among sexual minority women compared to heterosexual women: A meta-analysis

Posttraumatic stress disorder (PTSD) is more prevalent among sexual minority women (SMW) than among heterosexual women. PTSD risk varies among SMW, but no meta-analysis has clarified sexual identity-related disparities in probable PTSD among women or SMW's heterogeneity in PTSD risk. SMW are also at pronounced risk of comorbid PTSD and hazardous drinking (HD). However, the difference in comorbid PTSD/HD between SMW and heterosexual women is understudied. This meta-analysis aimed to provide a comprehensive understanding of differences between SMW and heterosexual women and among SMW across demographic characteristics. Peer-reviewed publications that were written in English and reported quantitative data on PTSD specific to SMW were included. Eligible publications (n = 45) were identified through a systematic search of 11 electronic databases, supplemented by a search of reference lists of relevant papers. We found that probable PTSD, PTSD symptom severity, and probable comorbid PTSD/HD are highly prevalent among SMW, with SMW of color, transgender and gender diverse people, and bi+ women (e.g., bisexual, pansexual, queer) being at greatest risk. These results emphasize the need to improve accurate assessment of trauma-related sequelae among SMW and to develop, disseminate, and implement culturally sensitive treatments to reduce PTSD and comorbid PTSD/HD among at-risk SMW.

Integrating genetics and transcriptomics to study major depressive disorder: a conceptual framework, bioinformatic approaches, and recent findings

Major depressive disorder (MDD) is a complex and heterogeneous psychiatric syndrome with genetic and environmental influences. In addition to neuroanatomical and circuit-level disturbances, dysregulation of the brain transcriptome is a key phenotypic signature of MDD. Postmortem brain gene expression data are uniquely valuable resources for identifying this signature and key genomic drivers in human depression; however, the scarcity of brain tissue limits our capacity to observe the dynamic transcriptional landscape of MDD. It is therefore crucial to explore and integrate depression and stress transcriptomic data from numerous, complementary perspectives to construct a richer understanding of the pathophysiology of depression. In this review, we discuss multiple approaches for exploring the brain transcriptome reflecting dynamic stages of MDD: predisposition, onset, and illness. We next highlight bioinformatic approaches for hypothesis-free, genome-wide analyses of genomic and transcriptomic data and their integration. Last, we summarize the findings of recent genetic and transcriptomic studies within this conceptual framework.

Primary sources of health care among LGBTQ+ veterans: Findings from the Behavioral Risk Factor Surveillance System

OBJECTIVE

This study examined the primary source of health care between veterans with lesbian, gay, bisexual, queer and similar identities (LGBTQ+) and non-LGBTQ+ veterans.

DATA SOURCES AND STUDY SETTING

Veterans (N = 20,497) from 17 states who completed the CDC's Behavioral Risk Factor Surveillance System from 2016 to 2020, including the Sexual Orientation and Gender Identity and Health Care Access modules.

STUDY DESIGN

We used survey-weighted multiple logistic regression to estimate average marginal effects of the prevalence of utilization of Veteran's Health Administration (VHA)/military health care reported between LGBTQ+ and non-LGBTQ+ veterans. Prevalence estimates were adjusted for age group, sex, race and ethnicity, marital status, educational attainment, employment status, survey year, and US state.

DATA COLLECTION METHODS

Study data were gathered via computer-assisted telephone interviews with probability-based samples of adults aged 18 and over. Data are publicly available.

PRINCIPAL FINDINGS

Overall, there was not a statistically significant difference in estimated adjusted prevalence of primary use of VHA/military health care between LGBTQ+ and non-LGBTQ+ veterans (20% vs. 23%, respectively, p = 0.13). When examined by age group, LGBTQ+ veterans aged 34 and younger were significantly less likely to report primary use of VHA/military health care compared to non-LGBTQ+ veterans (25% vs. 44%, respectively; p = 0.009). Similarly, in sex-stratified analyses, fewer female LGBTQ+ veterans than female non-LGBTQ+ veterans reported VHA/military health care as their primary source of care (13% vs. 29%, respectively, p = 0.003). Implications and limitations to these findings are discussed.

CONCLUSIONS

Female and younger LGBTQ+ veterans appear far less likely to use VHA/military for health care compared to their cisgender, heterosexual peers; however, because of small sample sizes, estimates may be imprecise. Future research should corroborate these findings and identify potential reasons for these disparities.

Social Stressors and Health Among Older Transgender and Gender Diverse Veterans

Purpose: Health disparities in transgender and gender diverse (TGD) veterans compared with cisgender veterans have been documented. However, there is a paucity of literature focused on older TGD veterans. We assessed health conditions and social stressors in older TGD veterans compared with matched cisgender veterans. Methods: Using gender identity disorder diagnosis codes, we identified 1244 TGD veterans (65+ years of age) receiving care in the Veterans Health Administration (VHA) from 2006 to 2018. These TGD veterans were then matched to 3732 cisgender veterans based on age, VHA site, and date of care in VHA. Results: In adjusted models, TGD veterans compared with cisgender veterans were less likely to have alcohol use disorder (adjusted odds ratio [AOR; 95% confidence interval]: [0.70; 0.58-0.85]), drug use disorder (0.59; 0.47-0.74), tobacco use (0.75; 0.65-0.86), and anxiety (0.74; 0.62-0.90). However, compared with cisgender veterans, TGD veterans were more likely to experience depression (1.63; 1.39-1.93), Alzheimer's disease (8.95; 4.25-18.83), cancer (1.83; 1.56-2.14), violence (1.82; 1.14-2.91), social/familial problems (2.45; 1.99-3.02), lack of access to care/transportation (2.23; 1.48-3.37), and military sexual trauma (2.59; 1.93-3.46). Furthermore, compared with cisgender veterans, TGD veterans were more likely to have documentation of a higher count of social stressors: 1 or more stressors (1.64; 1.38-1.95) and 2 or more stressors (1.22; 1.01-1.49). Conclusion: Despite significant disparities in social stressors and health conditions compared with cisgender veterans, TGD veterans had a lower likelihood of substance use and anxiety. Interventions are needed to mitigate social stressors and improve health among the older TGD veteran population.

Disparities in Mental Health and Health Risk Behaviors for LGBT Veteran Subgroups in a National U.S. Survey

Purpose: This study examined differences in mental health and health risk behaviors across sexual orientation and gender identity among U.S. veterans. Methods: Veterans were recruited through targeted social media advertising, community organizations, and listservs to complete an online survey (N = 1062). Generalized linear regression was used to evaluate differences in outcomes between subgroups, which included cisgender heterosexual men and women, lesbian women, gay men, bisexual men and women, transgender men and women, and veterans with other gender identities. Results: Transgender men and women reported a significantly higher prevalence of lifetime suicide plans and attempts compared to all other subgroups within the respective genders. Beyond this finding, patterns of all outcomes varied by gender. Compared to other subgroups of men, transgender men reported higher prevalence of posttraumatic stress disorder, whereas cisgender gay men reported higher prevalence of lifetime cocaine use and positive human immunodeficiency virus (HIV) status. Within the women subgroups, all LGBT subgroups reported higher prevalence of lifetime smoking and past-year marijuana use compared to heterosexual women. Cisgender lesbian women also reported higher prevalence of past-month heavy episodic drinking, and cisgender bisexual women reported higher prevalence of lifetime cocaine and stimulant use compared to other groups. Conclusion: Transgender women and men reported significantly higher prevalence of lifetime suicide plans and attempts than other groups, highlighting this as an area in need of urgent public health attention. Other disparity patterns indicated the importance of examining subgroups within the LGBT veteran community.
