Trauma exposure, mental health, and mental health treatment among LGBTQ+ veterans and nonveterans.

OBJECTIVE: The purpose of the study was to compare lesbian, gay, bisexual, transgender, queer+ (LGBTQ+) veterans' and nonveterans' prevalence of potentially traumatic events (PTEs) and other stressor exposures, mental health concerns, and mental health treatment. METHOD: A subsample of veterans and nonveterans who identified as LGBTQ+ (N = 1,291; 851 veterans; 440 nonveterans) were identified from a national cohort of post-9/11 veterans and matched nonveterans. Majority of the sample identified as White (59.7%), men (40.4%), and gay or lesbian (48.6%). Measures included PTEs and other stressors, depression, anxiety, posttraumatic stress disorder (PTSD), and receipt of mental health treatment. Logistic regressions compared the likelihood of experiencing PTEs and other stressors, self-reported mental health diagnoses, and mental health treatment between LGBTQ+ veterans and nonveterans. RESULTS: Compared with LGBTQ+ nonveterans, LGBTQ+ veterans were more likely to report financial strain, divorce, discrimination, witnessing the sudden death of a friend or family member, and experiencing a serious accident or disaster. LGBTQ+ veterans reported greater depression, anxiety, and PTSD symptom severity than LGBTQ+ nonveterans. However, LGBTQ+ veterans were only more likely to receive psychotherapy for PTSD and did not differ from nonveterans in the likelihood of receiving any other types of mental health treatment. CONCLUSIONS: The study was the first to demonstrate that LGBTQ+ veterans have a greater prevalence of PTEs and other stressors and report worse mental health symptoms. These findings suggest that LGBTQ+ veterans may have unmet mental health treatment needs and need interventions to increase engagement in needed mental health services, especially for depression and anxiety.

Quantifying relational change in community organisations participating in a Veteran suicide prevention learning collaborative: a social network analysis.

BACKGROUND: Veteran suicide remains a significant issue, as 17.5 Veterans die by suicide each day. The US Department of Veteran Affairs (VA) has implemented a robust suicide prevention program within its integrated behavioural health system. Further, the VA has increasingly contributed to suicide prevention in community settings, where a large proportion of Veterans receive health care and social services. One component integral to preventing suicide among Veterans receiving community services is ensuring that organisations are equipped with the latest evidence-based Veteran-specific suicide prevention strategies. METHODS: The Patient Safety Center of Inquiry-Suicide Prevention Collaborative piloted a Veteran suicide prevention learning collaborative in the Denver/Colorado Springs, CO region, spanning 16 months as a multimodal initiative to integrate community organisations and assist them in implementing Veteran suicide prevention strategies used within VA. Agencies completed social network analysis surveys at baseline (T1), year 1 (T2) and 16 months (T3) to examine social networks, partnerships and collaborations among community organisations and the VA over time. RESULTS: The quantity of learning collaborative relationships increased from 30 at T1 to 41 at T3 while the quality of relationships deepened over time from awareness and cooperative to more coordinated and integrated. CONCLUSION: Improvement in relationship quantity and quality facilitates community organisation engagement in collaborating to strengthen their Veteran suicide prevention programming. Learning collaboratives work with the individual organisation for intraorganisational facilitation of implementing suicide prevention strategies and engage and enhance interorganisational partnerships. This multimodal intervention can engage community organisations and provide a stronger safety net for Veterans at risk for suicide.

Gender differences in risk and resilience for suicidal thoughts and behaviors: A national longitudinal survey study of United States veterans with a recent suicide attempt.

BACKGROUND: This study reports on gender differences in psychosocial symptoms and suicidal thoughts and behaviors from the first longitudinal, national survey of veterans with a recent nonfatal suicide attempt to inform women-tailored suicide prevention. METHODS: We recruited all female veterans with a documented nonfatal suicide attempt between October 2018 and September 2019 and a stratified matched sample of males. Surveys were administered at baseline, month 6, and month 12; 968 veterans completed the baseline survey with valid gender data. Surveys assessed psychosocial constructs, suicidal ideation severity, and suicidal behavior. Administrative datasets provided healthcare and suicide attempt data during the one year follow up. RESULTS: Women retained higher social rejection and institutional betrayal, and lower self-compassion and autonomy than men over follow up. Higher overall self-compassion was associated with lower baseline suicide ideation for both women and men; however, this association was stronger for women (Δ = -0.19; 95 % CI = -0.31, -0.07; d = -0.15). Individuals with higher overall psychological distress had greater odds of a subsequent suicide attempt (AOR = 2.20, 95 % CI = 1.56, 3.11). Social rejection had the strongest association with worsening psychological distress, both within individuals (b = 0.18; 95 % CI = 0.14, 0.23; d = 0.23) and between individuals (b = 0.07; 95 % CI = 0.04, 0.10; d = 0.09). LIMITATIONS: Results may not generalize beyond a VHA-utilizing veteran population. CONCLUSIONS: Findings from this study inform potential therapeutic targets and topics for future research on tailoring suicide prevention for women veterans. While all veterans may need support reducing distress, women may need additional support in multiple other areas.

Suicide Prevention Programming: Comparing Four Prominent Frameworks.

OBJECTIVE: Suicide is a significant public health concern. About 48,000 individuals died by suicide in 2021 in the United States, and approximately one in 100 deaths globally are due to suicide. Continuing efforts in program development and evaluation are vital to preventing suicide. Multiple frameworks have been developed to reduce suicide rates, but they have not been compared to assess their comprehensiveness, nor have their components been classified. METHODS: In 2019, the authors conducted a narrative review of the literature and identified four major frameworks for suicide prevention: the U.S. Department of Veterans Affairs (VA) Suicide Prevention Program, the Defense Suicide Prevention Program of the U.S. Department of Defense, Zero Suicide in Health and Behavioral Health Care, and the technical package developed by the Centers for Disease Control and Prevention. Program components for these frameworks were identified and classified by using two prevention strategy classification systems: the National Academy of Medicine's (NAM's) continuum-of-care model and the Substance Abuse and Mental Health Services Administration's (SAMHSA's) prevention model. RESULTS: The cross-program comparison revealed that no single program included all components of suicide prevention programs. However, the VA program was the most comprehensive in terms of the number of components and their spread across prevention strategy classifications. The programs used few components categorized under NAM's promotion or selective prevention strategy classifications. The SAMHSA prevention strategy classifications of information dissemination, community-based processes, and positive alternatives were also used infrequently. CONCLUSIONS: Organizations, health care systems, and policy makers may use these findings as they develop, improve, and implement suicide prevention programs.

Perceived social support moderates the relations between mental health symptoms and current suicidal ideation.

Despite efforts to identify risk factors associated with suicidal ideation (SI), less work has been conducted to highlight protective factors to promote prevention. Perceived social support has been shown to positively impact a wide range of psychological outcomes; however, prior efforts exploring whether perceived social support moderates the relationship between mental health (MH) symptoms and current SI among men and women have been hampered by limitations. To address knowledge gaps, data from the Comparative Health Assessment Interview Research Study was used to evaluate whether (a) perceived social support moderates the relationship between mental health symptoms (posttraumatic stress, anxiety, alcohol use, depressive) and current SI among veterans and nonveterans; (b) the strength of this moderating effect varies by gender and veteran status; and (c) the strength of this moderating effect varies by social support source (significant other, friend, family). Results suggest that perceived social support is more protective against SI for those with lower levels of mental health symptoms (≤ 25th percentile) than for those with higher symptom levels (≥ 75th percentile). Findings were largely consistent across study groups, support sources, and mental health symptoms examined; however, a significant moderating effect on the alcohol use-SI relationship was only observed for veteran men. Those with a lower mental health symptom severity may receive more benefit from strategies aimed at increasing perceived social support compared to those with higher symptom severity. Research is needed to match protective factors to individual phenotypes, with the goal of engaging those living with SI in more effective interventions.

Divergent trends in accidental deaths since return from an Afghanistan/Iraq deployment among army soldiers.

PURPOSE: Accidental death is a leading cause of mortality among military members and Veterans; however, knowledge is limited regarding time-dependent risk following deployment and if there are differences by type of accidental death. METHODS: Longitudinal cohort study (N = 860,930) of soldiers returning from Afghanistan/Iraq deployments in fiscal years 2008-2014. Accidental deaths (i.e., motor vehicle accidents [MVA], accidental overdose, other accidental deaths), were identified through 2018. Crude and age-adjusted mortality rates, rate ratios, time-dependent hazard rates and trends postdeployment were compared across demographic and military characteristics. RESULTS: During the postdeployment observation period, over one-third of deaths were accidental; most were MVA (46.0 %) or overdoses (37.9 %). Across accidental mortality categories (all, MVA, overdose), younger soldiers (18-24, 25-29) were at higher risk compared to older soldiers (40+), and females at lower risk than males. MVA death rates were highest immediately postdeployment, with a significant decreasing hazard rate over time (annual percent change [APC]: -6.5 %). Conversely, accidental overdose death rates were lowest immediately following deployment, with a significant increasing hazard rate over time (APC: 9.9 %). CONCLUSIONS: Observed divergent trends in risk for the most common types of accidental deaths provide essential information to inform prevention and intervention planning for the immediate postdeployment transition and long-term.

Suicide Among Asian American, Native Hawaiian, and Pacific Islander Veterans: Rates and Methods, 2005-2019.

INTRODUCTION: Knowledge of suicide rates and methods among Asian American, Native Hawaiian, and Pacific Islander (AANHPI) Veterans remains sparse. Age- and sex-specific suicide rates, methods, and trends were examined among AANHPI Veterans and were compared with findings reported for all Veterans. METHODS: For this population-based retrospective cohort study, average annual suicide rates (2005-2019) were computed in 2023 using population (U.S. Veterans Eligibility Trends and Statistics) and mortality (National Death Index [NDI]) data. The cohort included 416,454 AANHPI Veterans (356,146 males, 60,229 females) separated from military service and alive as of 1/1/2005. Suicide was determined from NDI underlying cause-of-death ICD-10 codes. RESULTS: The age-adjusted average annual suicide rate among AANHPI Veterans increased 36.85% from 2005-2009 to 2015-2019 (2015-2019: 30.97/100,000). Relative to other ages, 2015-2019 suicide rates were highest among AANHPI Veterans 18-34 (overall: 53.52/100,000; males: 58.82/100,000; females: 32.24/100,000) and exceeded those of similarly aged Veterans in the overall Veteran population (overall: 44.71/100,000; males: 50.59/100,000; females: 19.24/100,000). The sex difference in suicide rates was lower among AANHPI Veterans than in Veterans overall (relative risk [males to females]=1.65 and 2.33, among those 18-54). Firearms were used less and suffocation more among AANHPI Veterans, relative to Veterans overall. CONCLUSIONS: Suicide among AANHPI Veterans is an increasing public health concern, with younger males and females at particularly elevated risk. Lethal means safety strategies for AANHPI Veterans should consider distinctions in suicide methods compared to the overall Veteran population. Research is warranted to understand the lower magnitude sex difference in suicide rates among AANHPI Veterans.

Which veterans with PTSD are most likely to report being told of their diagnosis?

Veterans who do not know about their posttraumatic stress disorder (PTSD) diagnosis experience a fundamental barrier to accessing effective treatment. Little is known about the characteristics that influence veterans' PTSD diagnosis knowledge (i.e., report of being told they have a PTSD diagnosis by a healthcare provider). Veterans who met probable and provisional criteria for PTSD on the self-report PTSD checklist for DSM-5 were identified from the Comparative Health Assessment Interview Research Study (n = 2335). Weighted logistic regression was performed to identify demographic variables, clinical characteristics, and social determinants of health (e.g., economic instability, homelessness, healthcare coverage) associated with PTSD diagnosis knowledge among post-9/11 veterans. Approximately 62% of veterans with probable and provisional PTSD had PTSD diagnosis knowledge. Predictors with the strongest associations included another mental health diagnosis (OR = 6.10, CI95:4.58,8.12) and having Veterans Affairs (VA) healthcare coverage (OR = 2.63, CI95:1.97,3.51). Veterans with combat or sexual trauma were more likely to have PTSD diagnosis knowledge than those with different trauma types. Results suggest veterans with VA healthcare coverage and military-related trauma are more likely to be informed by a healthcare professional about a PTSD diagnosis. Further research is needed to improve PTSD diagnosis knowledge for those with non-military-related trauma and those without VA healthcare coverage.

Identifying U.S. regions with the highest suicide rates and examining differences in suicide methods among Asian American, Native Hawaiian, and Pacific Islander Veterans.

The suicide rate among Asian American, Native Hawaiian, and Pacific Islander (AANHPI) Veterans increased from 2001 to 2020. Identifying regions where suicide rates are elevated and increasing among AANHPI Veterans would inform targeted prevention efforts for members of this cohort. We conducted a population-based retrospective cohort study of 377,833 AANHPI Veterans to examine suicide rates and methods (2005-2019) by United States (US) region and over time (2005-2009, 2010-2014, 2015-2019), using US Veteran Eligibility Trends and Statistics and Joint DoD/VA Mortality Data Repository data. AANHPI Veterans across most regions experienced increases in suicide rates from the earliest to latest period; however, patterns differed by region. Age-adjusted suicide rates increased across all three periods among those in the Northeast and West, but increased, then declined in the Midwest and South. In 2015-2019, the age-adjusted suicide rate among AANHPI Veterans was highest in the Northeast (42.0 per 100,000) and lowest in the West (27.5). However, the highest percentages of AANHPI Veteran suicide deaths in 2005-2019 occurred in the West (39.5%) and South (34.7%), with lower percentages in the Midwest (15.0%) and Northeast (10.8%). Across regions, those ages 18-34 had the highest suicide rates. Firearms were the most frequently used suicide method across regions (44.4%-60.2%), except the Northeast (35.2%), where suffocation was more common (38.3%). Results suggest particular needs for suicide prevention efforts among AANHPI Veterans in the Northeast and to ensure that lethal means safety initiatives for AANHPI Veterans encompass both firearms and suffocation, with some variations in emphasis across regions.

Relationship between Veterans Crisis Line risk rating and subsequent suicidal self-directed violence among veteran callers: A gender comparison.

BACKGROUND: Disparities in suicide rates by veteran status are particularly striking for women. Veterans Crisis Line (VCL) is a preventive strategy. OBJECTIVES: Examine the relationships and gender differences between VCL risk rating, and subsequent suicidal self-directed violence (SSDV) in the 12-months following VCL index call. METHODS: Cohort study of VCL callers in 2018. OUTCOMES: Dichotomized composite SSDV (non-fatal suicide event and/or suicide) in the 12 months following VCL call. RESULTS: Veterans with high/moderate VCL risk had significantly higher odds of SSDV (OR = 4.02, 95% CI: 3.75, 4.30). There were no gender/VCL risk interaction (p = 0.3605). We also examined the association of gender, combination of VCL risk and suicide attempt (SA) history, on SSDV. Differential odds of SSDV for gender and combined VCL risk and SA history combinations were observed (p = 0.0005). Compared to those with lower VCL risk without SA history, those with high/moderate VCL risk with SA history showed higher odds of SSDV. Magnitude was higher for men, than for women veterans. CONCLUSIONS AND RELEVANCE: Veterans Crisis Line risk assessment performs relatively stable across the gender binary and highlights potential gender differences when factoring in SA history. Combining risk assessment and attempt history may lead to effective suicide prevention strategies.

Veteran Engagement in Survey Research to Prevent Suicide.

Suicide rates among veterans remain high, underscoring the necessity of identifying modifiable suicide risk and protective factors that can be targeted through public health approaches. One way to ensure that survey-based research yields information necessary to translate findings into patient-centered interventions is through veteran engagement. The current manuscript describes perspectives of members of a national Veterans Engagement Board (VEB) in contributing to the Assessing Social and Community Environments with National Data (ASCEND) for Veteran Suicide Prevention project. Contributions have included strengthening communication with potential veteran participants, addressing sensitive survey topics such as firearms and suicide, and ensuring that ASCEND is responsive to current national and global events. Additionally, Veterans Engagement Board members described the personal impact of engagement. These contributions highlight the value of veteran engagement as an integral component of suicide risk and prevention research.

Associations of Military-Related Traumatic Brain Injury With New-Onset Mental Health Conditions and Suicide Risk.

Importance: Research to identify the direct and indirect associations of military-related traumatic brain injury (TBI) with suicide has been complicated by a range of data-related challenges. Objective: To identify differences in rates of new-onset mental health conditions (ie, anxiety, mood, posttraumatic stress, adjustment, alcohol use, and substance use disorders) among soldiers with and without a history of military-related TBI and to explore the direct and indirect (through new-onset mental health disorders) associations of TBI with suicide. Design, Setting, and Participants: This retrospective cohort study used data from the Substance Use and Psychological Injury Combat Study (SUPIC) database. Demographic, military, and health data from the Department of Defense within SUPIC were compiled and linked with National Death Index records to identify deaths by suicide. Participants included US Army soldiers who returned from an Afghanistan or Iraq deployment. Data were analyzed from September to December 2022. Exposures: Military-related TBI. Main Outcomes and Measures: The outcome of interest was suicide. Secondary outcomes were incidence of new-onset mental health conditions. Mediation analyses consisted of accelerated failure time (AFT) models in conjunction with the product of coefficients method. The 6 new-onset mental health diagnosis categories and the 2 or more categories variable were each considered separately as potential mediators; therefore, a total of 14 models plus the overall AFT model estimating the total effect associated with TBI in suicide risk were fit. Results: The study included 860 892 soldiers (320 539 soldiers [37.2%] aged 18-24 at end of index deployment; 766 454 [89.0%] male), with 108 785 soldiers (12.6%) with at least 1 documented TBI on their military health record. Larger increases in mental health diagnoses were observed for all conditions from before to after documented TBI, compared with the matched dates for those without a history of TBI, with increases observed for mood (67.7% vs 37.5%) and substance use (100% vs 14.5%). Time-to-suicide direct effect estimates for soldiers with a history of TBI were similar across mediators. For example, considering new-onset adjustment disorders, time-to-suicide was 16.7% faster (deceleration factor, 0.833; 95% CI, 0.756-0.912) than for soldiers without a history of TBI. Indirect effect estimates of associations with TBI were substantial and varied across mediators. The largest indirect effect estimate was observed through the association with new-onset substance use disorder, with a time to suicide 63.8% faster (deceleration factor, 0.372; 95% CI, 0.322-0.433) for soldiers with a history of TBI. Conclusions and Relevance: In this longitudinal cohort study of soldiers, rates of new-onset mental health conditions were higher among individuals with a history of TBI compared with those without. Moreover, risk for suicide was both directly and indirectly associated with history of TBI. These findings suggest that increased efforts are needed to conceptualize the accumulation of risk associated with multiple military-related exposures and identify evidence-based interventions that address mechanisms associated with frequently co-occurring conditions.

The perceived impact of pandemic scale (PIPS): Initial development and examination among U.S. military veterans.

The COVID-19 pandemic has had significant impacts, including increases in mental health problems, distress, interpersonal conflict, unemployment, loss of income, housing instability, and food insecurity. Veterans may be particularly vulnerable to such impacts given their burden of mental and physical health problems. Few existing measures assess pandemic impact, and none have been validated for use with Veterans. We developed such a measure (the Perceived Impact of the Pandemic Scale; PIPS) and examined its psychometric performance in a national sample of US Veterans. Survey data from 567 Veterans were collected between 12/2020 and 2/2021. To examine PIPS factor structure, split sample exploratory/confirmatory factor analyses (EFA/CFA) were conducted to identify and test the most plausible model among an initial set of 18 items. Based on tests of factor extraction and factor loadings, 15 items clearly loaded onto three distinct factors. Internal reliability of all factors was ω > 0.8 and CFA model fit was good (χ2(87) = 167.39, p < .001; SRMR = 0.068; RMSEA = 0.060 [95% CI: 0.05, 0.07], CFI = 0.92). Mean factor scores were significantly positively correlated with measures of depression and loneliness, and negatively correlated with perceived social support. Results suggest the PIPS assesses three internally reliable factors comprised of perceived impact of the pandemic on interpersonal relationships, financial impact, and personal health and well-being. Construct validity with US Veterans was supported. The PIPS may be useful for examining the potentially disparate impact of pandemics on different populations. Research is needed to validate the PIPS in non-Veteran populations.

A pilot of a veteran suicide prevention learning collaborative among community organizations: Initial results and outcomes.

INTRODUCTION: Veteran suicide remains an ongoing public health concern in need of fresh, community-based initiatives. The Department of Veterans Affairs (VA) has built an enterprise-wide integrated behavioral health system that has pioneered numerous suicide prevention methods. However, most Veterans receive healthcare outside the VA, from organizations that may not be equipped to address Veteran suicide risk. One solution is implementing a VA/community suicide prevention learning collaborative to support organizations in implementing suicide prevention best practices for Veterans. Although learning collaboratives have a history of supporting improved patient safety in healthcare systems, to our knowledge, none have focused on Veteran suicide prevention. METHOD: The current quality improvement project sought to pilot a VA/community suicide prevention learning collaborative in the broader Denver and Colorado Springs areas with 13 organizations that served, interacted with, or employed Veterans. RESULTS: The collaborative had a large footprint in the region, with organizations interacting with over 24,000 community members and over 5000 Veterans. Organizations implemented 92 Veteran suicide prevention program components within a 16-month period. Overall, the learning collaborative made significant strides in Veteran suicide prevention. CONCLUSION: Findings suggest that this method facilitates rapid implementation of Veteran suicide prevention practices and may be promising for accelerating uptake within communities.

Military sexual trauma among Veterans using and not using VA justice-related programing: A national examination.

Veterans accessing Department of Veterans Affairs (VA) Veterans Justice Program (VJP) services have high rates of depression, substance misuse, and posttraumatic stress disorder. Although factors that may confer risk for mental health sequelae among these Veterans have been identified (e.g., childhood abuse, combat exposure), limited research has examined report of military sexual trauma (MST) among Veterans accessing VJP services. As survivors of MST experience myriad chronic health conditions which necessitate identification and referral to evidence-based care, identifying MST survivors among those accessing VJP services may facilitate referral to appropriate services. We examined whether MST prevalence differed between Veterans with and without a history of VJP service use. Sex-stratified analyses were conducted with 1,300,252 male (13.34% accessing VJP) and 106,680 female (10.14% accessing VJP) Veterans. In crude models, male and female Veterans accessing VJP services were significantly more likely to screen positive for MST (PR = 3.35 and 1.82 respectively). Significance was maintained in models that adjusted for age, race/ethnicity, VA service use, and VA mental health use. VJP service settings may serve as a critical intercept for identifying male and female survivors of MST. Using a trauma-informed approach to screen for MST in VJP settings is likely warranted. Moreover, integration of MST programing into VJP settings may be beneficial.

Relationship of social determinants of health with symptom severity among Veterans and non-Veterans with probable posttraumatic stress disorder or depression.

PURPOSE: Social determinants of health (SDoH) refer to the conditions in the environments in which people live that affect health outcomes and risks. SDoH may provide proximal, actionable targets for interventions. This study examined how SDoH are associated with posttraumatic stress disorder (PTSD) and depression symptoms among Veterans and non-Veterans with probable PTSD or depression. METHODS: Four multiple regressions were conducted. Two multiple regressions with Veterans examined the impact of SDoH on PTSD symptoms and on depression symptoms. Two multiple regressions with non-Veterans examined the impact of SDoH on PTSD symptoms and on depression symptoms. Independent variables included demographic characteristics, adverse experiences (in childhood and adulthood), and SDoH (discrimination, education, employment, economic instability, homelessness, justice involvement, and social support). Correlates that were statistically significant (p < 0.05) and clinically meaningful (rpart >|0.10|) were interpreted. RESULTS: For Veterans, lower social support (rpart = - 0.14) and unemployment (rpart = 0.12) were associated with greater PTSD symptoms. Among non-Veterans, greater economic instability (rpart = 0.19) was associated with greater PTSD symptoms. In the depression models, lower social support (rpart = - 0.23) and greater economic instability (rpart = 0.12) were associated with greater depression for Veterans, while only lower social support was associated with greater depression for non-Veterans (rpart = - 0.14). CONCLUSION: Among Veterans and non-Veterans with probable PTSD or depression, SDoH were associated with PTSD and depression symptoms, particularly social support, economic instability, and employment. Beyond direct treatment of mental health symptoms, addressing social support and economic factors such as instability and employment in the context of PTSD and depression are potential intervention targets that would benefit from future research.

Racial and Ethnic Differences in Deaths by Suicide, Drug Overdose, and Opioid-Related Overdose in a National Sample of Military Members With Mild Traumatic Brain Injury, 1999-2019.

OBJECTIVE: To examine racial and ethnic differences in suicide and drug and opioid-related overdose deaths among a population-based cohort of military service members who were diagnosed with a mild traumatic brain injury (mTBI) during military service. DESIGN: Retrospective cohort. SETTING: Military personnel receiving care within the Military Health System between 1999 and 2019. PARTICIPANTS: In total, 356 514 military members aged 18 to 64 years, who received an mTBI diagnosis as their index TBI between 1999 and 2019, while on active duty or activated. MAIN MEASURES: Death by suicide, death by drug overdose, and death by opioid overdose were identified using International Classification of Diseases, Tenth Revision (ICD-10) codes within the National Death Index. Race and ethnicity were captured from the Military Health System Data Repository. RESULTS: Overall crude rates were 38.67 per 100 000 person-years for suicide; 31.01 per 100 000 person-years for drug overdose death; and 20.82 per 100 000 person-years for opioid overdose death. Crude and age-specific rates for military members who self-identified as Other were higher than all other racial/ethnic groups for all 3 mortality outcomes. Adjusting for age, suicide rates for those classified as Other were up to 5 times that of other racial/ethnic groups for suicide, and up to 11 and 3.5 times that of other race/ethnicity groups for drug and opioid overdose death, respectively. CONCLUSION: Findings extend previous knowledge regarding risk for suicide and deaths by drug overdose among those with mTBI and highlight new important areas for understanding the impact of race and ethnicity on mortality. Methodological limitations regarding classification of race and ethnicity must be addressed to ensure that future research provides a better understanding of racial and ethnic disparities in suicide and drug overdose mortality among military members with TBI.

Suicide risk and prevention in Guam: Clinical and research considerations and a call to action.

The suicide rate in Guam, a United States (U.S.) territory, is markedly higher than the suicide rate within the U.S. There are also important differences in who is most at risk for suicide in Guam, relative to within the general U.S. Understanding these distinctions is important for implementing effective suicide prevention initiatives in this region. In the current article, we discuss considerations for preventing suicide in Guam, including distinctions in suicide risk, relative to within the general U.S. For example, suicide rates in Guam are highest for those who are Pacific Islander, young, or male. Further, suicide in Guam more commonly involves hanging and less commonly involves firearms, a pattern that differs from suicide methods used within the general U.S. Additional considerations include the large military and Veteran population in Guam, as well as cultural and religious beliefs regarding suicide. Finally, given the geographic isolation of Guam, access to healthcare is likely an important facet of suicide risk. Considering these characteristics, it is imperative to develop and implement culturally-sensitive suicide prevention interventions for individuals residing in this region. We conclude by discussing future research avenues to address critical knowledge gaps to prevent suicide in Guam.
