Evaluation of Suicide Mortality Among Sexual Minority US Veterans From 2000 to 2017

Sexual and Gender Minority Status and Suicide Mortality: An Explainable Artificial Intelligence Analysis

Objectives: Suicide risk is elevated in lesbian, gay, bisexual, and transgender (LGBT) individuals. Limited data on LGBT status in healthcare systems hinder our understanding of this risk. This study used natural language processing to extract LGBT status and a deep neural network (DNN) to examine suicidal death risk factors among US Veterans. Methods: Data on 8.8 million veterans with visits between 2010 and 2017 was used. A case-control study was performed, and suicide death risk was analyzed by a DNN. Feature impacts and interactions on the outcome were evaluated. Results: The crude suicide mortality rate was higher in LGBT patients. However, after adjusting for over 200 risk and protective factors, known LGBT status was associated with reduced risk compared to LGBT-Unknown status. Among LGBT patients, black, female, married, and older Veterans have a higher risk, while Veterans of various religions have a lower risk. Conclusion: Our results suggest that disclosed LGBT status is not directly associated with an increase suicide death risk, however, other factors (e.g., depression and anxiety caused by stigma) are associated with suicide death risks.

Non-affirmation minority stress, internalized transphobia, and subjective cognitive decline among transgender and gender diverse veterans aged 45 years and older

OBJECTIVES

To examine the associations of two measures of minority stress, non-affirmation minority stress and internalized transphobia, with subjective cognitive decline (SCD) among transgender and gender diverse (TGD) veterans.

METHOD

We administered a cross-sectional survey from September 2022 to July 2023 to TGD veterans. The final analytic sample included 3,152 TGD veterans aged ≥45 years. We used a generalized linear model with quasi-Poisson distribution to calculate prevalence ratios (PR) and 95% confidence intervals (CIs) measuring the relationship between non-affirmation minority stress and internalized transphobia and past-year SCD.

RESULTS

The mean age was 61.3 years (SD = 9.7) and the majority (70%) identified as trans women or women. Overall, 27.2% (n = 857) reported SCD. Adjusted models revealed that TGD veterans who reported experiencing non-affirmation minority stress or internalized transphobia had greater risk of past-year SCD compared to those who did not report either stressor (aPR: 1.09, 95% CI: 1.04-1.15; aPR: 1.19, 95% CI: 1.12-1.27).

CONCLUSION

Our findings demonstrate that proximal and distal processes of stigma are associated with SCD among TGD veterans and underscore the need for addressing multiple types of discrimination. Above all, these results indicate the lasting sequelae of transphobia and need for systemic changes to prioritize the safety and welfare of TGD people.

Differences by Sexual Orientation in Patient-Centered Care Outcomes for Veterans Utilizing Primary Care Services at the Veterans Health Administration

Purpose: This study examined the differences by sexual orientation in patient-centered care outcomes (including health care experiences and health-related screening) of veterans utilizing Veterans Health Administration (VHA) primary care. Methods: VHA's adapted version of the Consumer Assessment of Healthcare Providers and Systems was used to compare the health care experience of primary care services among sexual minority (SM) and heterosexual veterans. Health care experience measures were dichotomized to "always" versus "less" and stratified by SM status. Health-related screening measures were dichotomous. Survey data were weighted using provided sample weights. Descriptive statistics were performed on sociodemographic characteristics. Logistic regression coefficients were represented as adjusted odds ratios (aORs). A total of 66,348 veterans were included in the analytic sample, of which 2.9% (n = 1,935) identified as SM. Sexual orientation was ascertained by self-report measures by veterans. Results: SM veterans were significantly younger (56.95 years vs. 63.43 years, p < 0.001), were less likely to report that their provider showed respect for what they had to say (aOR: 0.76; 95% confidence interval [CI]: 0.61-0.95), that they were asked about difficulties taking care of their health (aOR: 0.81; 95% CI: 0.67-0.96), and their provider listened carefully to them (aOR: 0.71; 95% CI: 0.57-0.87) compared to heterosexual veterans. Conclusion: Health care experiences differed between SM and heterosexual veterans who sought VHA primary care, suggesting the need to increase provider trainings, which may improve cultural competency and promote a more welcoming and inclusive environment.

Sexual Orientation and Disclosure of Suicidal Thoughts Before Suicide Mortality

INTRODUCTION

Disclosure of suicidal thoughts and behaviors represents an opportunity to intervene before suicide mortality, representing a cornerstone for suicide prevention. Sexual minority (e.g., lesbian/gay, bisexual) people experience sharply elevated suicide risk, yet there is scant research on patterns of disclosure of suicidal thoughts and behaviors before suicide that might uncover missed opportunities for suicide prevention. Thus, authors leveraged postmortem suicide data to evaluate associations among sexual orientation, sex, and disclosure of suicidal thoughts and behaviors in the month preceding death.

METHODS

Data on suicides from the 2013-2019 National Violent Death Reporting System (N=155,516) were classified for sexual orientation and denoted disclosure of suicidal thoughts and behaviors and to whom suicidal thoughts and behaviors were disclosed in the month preceding death. Logistic regression models stratified by sex and adjusted for sociodemographic covariates assessed the associations between sexual orientation and suicidal thoughts and behaviors disclosure. Analyses were conducted from October 2022 to February 2023.

RESULTS

Among females, sexual minority decedents were 65% more likely to disclose suicidal thoughts and behaviors than heterosexual decedents (95% CI=37%, 99%, p<0.001). No difference in suicidal thoughts and behaviors disclosure was observed between sexual minority and heterosexual men. Of decedents who disclosed suicidal thoughts and behaviors, one in five sexual minority decedents disclosed to a friend/colleague, whereas fewer than 5% disclosed to a healthcare professional. Among sexual minority females, younger age, intimate partner problems, and physical health problems were positively associated with disclosing suicidal thoughts and behaviors.

CONCLUSIONS

These findings suggest that reducing suicide mortality in sexual minority populations will require considering contexts beyond the healthcare system, including engaging peer networks. Gatekeeper training for suicide prevention may be an especially promising approach for reducing suicide among sexual minority women.

Developing a brief assessment of social risks for the Veterans Health Administration Survey of Healthcare Experiences of Patients

OBJECTIVE

To determine whether a 6- or 12-month look-back period affected rates of reported social risks in a social risk survey for use in the Veterans Health Administration and to assess associations of social risks with overall health and mental health.

STUDY DESIGN

Cross-sectional survey of respondents randomized to 6- or 12-month look-back period.

DATA SOURCES AND STUDY SETTING

Online survey with a convenience sample of Veterans in June and July 2021.

DATA COLLECTION/EXTRACTION METHODS

Veteran volunteers were recruited by email to complete a survey assessing social risks, including financial strain, adult caregiving, childcare, food insecurity, housing, transportation, internet access, loneliness/isolation, stress, discrimination, and legal issues. Outcomes included self-reported overall health and mental health. Chi-squared tests compared the prevalence of reported social risks between 6- and 12-month look-back periods. Spearman correlations assessed associations among social risks. Bivariate and multivariable logistic regression models estimated associations between social risks and fair/poor overall and mental health.

PRINCIPAL FINDINGS

Of 3418 Veterans contacted, 1063 (31.10%) responded (87.11% male; 85.61% non-Hispanic White; median age = 70, interquartile range [IQR] = 61-74). Prevalence of most reported social risks did not significantly differ by look-back period. Most social risks were weakly intercorrelated (median |r| = 0.24, IQR = 0.16-0.31). Except for legal issues, all social risks were associated with higher odds of fair/poor overall health and mental health in bivariate models. In models containing all significant social risks from bivariate models, adult caregiving and stress remained significant predictors of overall health; food insecurity, housing, loneliness/isolation, and stress remained significant for mental health.

CONCLUSIONS

Six- and 12-month look-back periods yielded similar rates of reported social risks. Although most individual social risks are associated with fair/poor overall and mental health, when examined together, only adult caregiving, stress, loneliness/isolation, food, and housing remain significant.

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.

Adverse Childhood Experiences Among Lesbian, Gay, Bisexual, and Queer Veterans

INTRODUCTION

Adverse childhood experiences portend vulnerability to numerous physical and mental health concerns across the lifespan. Separate bodies of work suggest that both lesbian, gay, bisexual, and queer individuals and military veterans are more likely to report adverse childhood experiences than their non-lesbian, gay, bisexual, and queer and non-veteran counterparts, respectively. Although lesbian, gay, bisexual, and queer veterans experience health disparities compared with non-lesbian, gay, bisexual, and queer veterans, the prevalence of adverse childhood experiences among individuals with both lesbian, gay, bisexual, and queer and veteran identities is yet unknown.

METHODS

Participants were U.S. military veterans (N=14,461) from 18 states that included Sexual Orientation and Gender Identity and adverse childhood experiences modules in the 2019 and 2020 Behavioral Risk Factor Surveillance System survey. Multivariable logistic regression was used to determine the odds of adverse childhood experiences reported by lesbian, gay, bisexual, and queer veterans compared with those reported by non-lesbian, gay, bisexual, and queer veterans. Analyses were conducted in 2023.

RESULTS

While accounting for sociodemographic factors, lesbian, gay, bisexual, and queer veterans were more likely to report living with someone who experienced mental illness (AOR=2.17, 95% CI=1.35, 3.51), emotional abuse (AOR=1.58, 95% CI=1.11, 2.25), and sexual abuse (AOR=2.21, 95% CI=1.29, 3.76) than non-lesbian, gay, bisexual, and queer veterans.

CONCLUSIONS

With past work indicating that childhood abuse experiences are especially predictive of adverse health in adulthood, these findings suggest that a higher prevalence of adverse childhood experiences among lesbian, gay, bisexual, and queer veterans may contribute to health disparities among this population.

The Association of Military Sexual Harassment/Assault With Suicide Ideation, Plans, Attempts, and Mortality Among US Service Members/Veterans: A Meta-Analysis

Suicide rates continue to increase among service members/veterans. Military sexual harassment/assault (MSH/A) may increase risk of suicide, but little is known about the collective magnitude of associations between MSH/A and suicide outcomes, including ideation, plan, attempt, and mortality. The current meta-analysis addressed this literature gap while testing potential moderators of gender, marital status, discharge status, and military branch. PsycINFO, PubMed, Dissertations/Theses, relevant citation lists, and conference brochures were reviewed for papers that included quantitative analyses in English, U.S. military samples, and measures of MSH/A and suicide ideation/plan/attempt/mortality. The search resulted in 22 studies (N = 10,898,875) measuring the association of MSH/A with suicide ideation (k = 15), plans (k = 1), attempts (k = 14), and mortality (k = 2), with papers published from 2007-2021. MSH/A was associated with suicide ideation (r   ¯ = .14) and attempts (r   ¯ = .11, ps < .05). The association of MSH/A and suicide ideation and attempts was higher among women relative to men, those identifying as married versus not married, those actively serving compared to discharged, and those reporting service in the Air Force relative to all other branches. The association of MSH/A with suicide plans and mortality was not calculated due to the small number of studies reporting those effect sizes (ks = 1-2). The effect sizes observed suggest MSH/A is part of a larger network of risk factors for suicide. Moderators indicate that suicide risk is higher among specific groups, and prevention strategies would be most effective if they targeted these individuals. This research area would be strengthened by additional studies of plans and mortality.

Association of Sexual Orientation with Exposure to Suicide and Related Emotional Distress among US Adults

OBJECTIVE

Suicide bereavement is a significant public health concern. Using nationally representative survey data, we quantify sexual orientation differences in frequency of suicide exposure and suicide exposure-related emotional distress among US adults.

METHODS

We used cross-sectional data from the 2016 General Social Survey (GSS) and included sexual minority (i.e., lesbian, gay, bisexual; (n = 74, 5.3%) and heterosexual (n = 1,207, 94.7%) adults. The GSS asked several questions related to suicide exposure including number of lifetime suicide exposures, emotional distress related to suicide exposure, time elapsed since suicide exposure, and relationship(s) and perceived closeness to the person(s) who died. We use descriptive statistics to describe differences in suicide exposure characteristics across sexual orientation. Among those who were exposed to at least one suicide (n = 698, 51.1%), a weighted multivariable logistic regression model examined the association between sexual orientation and suicide exposure-related emotional distress adjusting for confounders.

RESULTS

Sexual minorities reported a similar number of lifetime suicide exposures and were not significantly different from heterosexuals on other suicide exposure characteristics. However, sexual minority, compared to heterosexual, respondents experienced 3.14 greater odds of severe emotional distress related to suicide exposure (95% CI = 1.42-6.94, p = .005).

CONCLUSION

Perhaps due to stigmatizing mourning experiences, sexual minority adults are particularly vulnerable to severe suicide exposure-related emotional distress. Future research to understand the scope of sexual minority-specific bereavement support services and public policies (e.g., bereavement leave) as well as intervention development to support sexual minority adults' coping in the wake of suicide exposure is warranted. HIGHLIGHTSApproximately half of sexual minority US adults report a lifetime suicide exposureSexual minority adults experience more severe suicide exposure-related emotional distressPostvention care should be tailored to meet the needs of sexual minority adults.

Disparities in Suicide-Related Behaviors Across Sexual Orientations by Gender: A Retrospective Cohort Study Using Linked Health Administrative Data

OBJECTIVE

The authors used a population-representative sample and health administrative data to quantify suicide-related behavior leading to acute care or deaths across self-identified heterosexual, gay/lesbian, and bisexual individuals.

METHODS

Data from a population-based survey (N=123,995) were linked to health administrative data (2002-2019), and differences in time to suicide-related behavior events across sexual orientations were examined using Cox proportional hazards regression.

RESULTS

The crude incidence rates of suicide-related behavior events per 100,000 person-years were 224.7 for heterosexuals, 664.7 for gay/lesbian individuals, and 5,911.9 for bisexual individuals. In fully adjusted (gender-combined) models, bisexual individuals were 2.98 times (95% CI=2.08-4.27) more likely to have an event, and gay men and lesbians 2.10 times (95% CI=1.18-3.71) more likely, compared with heterosexual individuals.

CONCLUSIONS

In a large population-based sample of Ontario residents, using clinically relevant outcomes, the study found gay/lesbian and bisexual individuals to be at elevated risk of suicide-related behavior events. Increased education among psychiatric professionals is needed to improve awareness of and sensitivity to the elevated risk of suicide-related behavior among sexual minority individuals, and further research on interventions is needed to reduce such behaviors.

The association between all-cause mortality and HIV acquisition risk groups in the United States, 2001-2014

OBJECTIVE

To investigate associations between all-cause mortality and human immunodeficiency virus (HIV) acquisition risk groups among people without HIV in the United States.

METHODS

We used data from 23,657 (NHANES) participants (2001-2014) and the Linked Mortality File to classify individuals without known HIV into HIV acquisition risk groups: people who ever injected drugs (ever-PWID); men who have sex with men (MSM); heterosexually active people at increased risk for HIV (HIH), using low income as a proxy for increased risk. We used Cox proportional hazards models to estimate adjusted and unadjusted all-cause mortality hazard ratios (HR) with 95% confidence intervals (CI).

RESULTS

Compared with sex-specific heterosexually active people at average risk for HIV (HAH), the adjusted HR (95% CI) were: male ever-PWID 1.67 (1.14, 2.46), female ever-PWID 3.50 (2.04, 6.01), MSM 1.51 (1.00, 2.27), male HIH 1.68 (1.04, 2.06), female HIH 2.35 (1.87, 2.95), and male ever-PWID 1.67 (1.14, 2.46).

CONCLUSIONS

Most people at increased risk for HIV in the US experience higher all-cause mortality than people at average risk. Strategies addressing social determinants that increase HIV risk should be incorporated into HIV prevention and other health promotion programs.

Complex modeling with detailed temporal predictors does not improve health records-based suicide risk prediction

Suicide risk prediction models can identify individuals for targeted intervention. Discussions of transparency, explainability, and transportability in machine learning presume complex prediction models with many variables outperform simpler models. We compared random forest, artificial neural network, and ensemble models with 1500 temporally defined predictors to logistic regression models. Data from 25,800,888 mental health visits made by 3,081,420 individuals in 7 health systems were used to train and evaluate suicidal behavior prediction models. Model performance was compared across several measures. All models performed well (area under the receiver operating curve [AUC]: 0.794-0.858). Ensemble models performed best, but improvements over a regression model with 100 predictors were minimal (AUC improvements: 0.006-0.020). Results are consistent across performance metrics and subgroups defined by race, ethnicity, and sex. Our results suggest simpler parametric models, which are easier to implement as part of routine clinical practice, perform comparably to more complex machine learning methods.

Recommended practices and ethical considerations for natural language processing-assisted observational research: A scoping review

An increasing number of studies have reported using natural language processing (NLP) to assist observational research by extracting clinical information from electronic health records (EHRs). Currently, no standardized reporting guidelines for NLP-assisted observational studies exist. The absence of detailed reporting guidelines may create ambiguity in the use of NLP-derived content, knowledge gaps in the current research reporting practices, and reproducibility challenges. To address these issues, we conducted a scoping review of NLP-assisted observational clinical studies and examined their reporting practices, focusing on NLP methodology and evaluation. Through our investigation, we discovered a high variation regarding the reporting practices, such as inconsistent use of references for measurement studies, variation in the reporting location (reference, appendix, and manuscript), and different granularity of NLP methodology and evaluation details. To promote the wide adoption and utilization of NLP solutions in clinical research, we outline several perspectives that align with the six principles released by the World Health Organization (WHO) that guide the ethical use of artificial intelligence for health.

A Practical Review of Suicide Among Veterans: Preventive and Proactive Measures for Health Care Institutions and Providers

Suicide rates among veterans are higher than those of the general US population. Although veterans compose only 7.6% of the US population, nearly 14% of American adult suicides are among veterans. The rate of suicide is 1.5 times higher among all veterans and 2.1 times higher among female veterans compared with the general population. Only 47% of all veterans are enrolled in the US Department of Veterans Affairs (VA) Healthcare System, leaving a large number either not receiving health care or receiving it outside the VA. Recent legislation has improved access to care for veterans outside the VA, highlighting the need for a broad public health approach to address veteran suicide and the need for all health care institutions and clinicians to be familiar with the unique health concerns in this population. The purpose of this narrative review was to summarize the risk factors contributing to veteran suicide and to provide guidance on how to assess and mitigate these risks. Suicide is preventable through recognition of risk and prompt intervention. Health care providers both inside and outside the VA system are uniquely situated at the intersection of the many contributing factors to veteran suicide and should have a structured, proactive approach to address the problem.

Mental Health Service Use Among Lesbian, Gay, and Bisexual Adults Who Report Having Attempted Suicide

OBJECTIVE

This study estimated mental health service use among lesbian, gay, and bisexual (LGB) adults in the United States who reported having made a suicide attempt.

METHODS

Data came from the pooled 2015-2019 National Surveys on Drug Use and Health. Of the 191,954 adult respondents, 1,946 reported a past-year suicide attempt. Survey-weighted descriptive and regression analyses were conducted to compare mental health service use among LGB and heterosexual adults.

RESULTS

Three percent of LGB adults (N=598) reported having attempted suicide in the past year, compared with 0.5% of heterosexual adults (N=1,348). Mental health treatment use was significantly higher among LGB adults than among heterosexual adults (64% versus 56%) before analyses were adjusted for sociodemographic characteristics.

CONCLUSIONS

Because suicide attempts and mental health use are elevated among LGB adults, clinicians must provide evidence-based approaches for identifying and managing suicide risk to LGB adults in an affirming manner.

Suicide attempts and mental health diagnoses in combat-injured service members: A retrospective cohort study

INTRODUCTION

Examinations of risk factors for suicide attempt in United States service members at high risk of mental health diagnoses, such as those with combat injuries, are essential to guiding prevention and intervention efforts.

METHODS

Retrospective cohort study of 8727 combat-injured patients matched to deployed, non-injured patients utilizing Department of Defense and Veterans Affairs administrative records.

RESULTS

Combat injury was positively associated with suicide attempt in the univariate model (HR = 1.75, 95% CI 1.5-2.1), but lost significance after adjustment for mental health diagnoses. Utilizing Latent Transition Analysis in the combat-injured group, we identified five mental/behavioral health profiles: (1) Few mental health diagnoses, (2) PTSD and depressive disorders, (3) Adjustment disorder, (4) Multiple mental health comorbidities, and (5) Multiple mental health comorbidities with alcohol use disorder (AUD). Multiple mental health comorbidities with AUD had the highest suicide attempt rate throughout the study and more than four times that of Multiple mental health comorbidities in the first study year (23.4 vs. 5.1 per 1000 person years, respectively).

CONCLUSION

Findings indicate that (1) combat injury's impact on suicide attempt is attenuated by mental health and (2) AUD with multiple mental health comorbidities confers heightened suicide attempt risk in combat-injured service members.

Comparing mental and physical health of U.S. veterans by VA healthcare use: implications for generalizability of research in the VA electronic health records

OBJECTIVE

The Department of Veterans Affairs' (VA) electronic health records (EHR) offer a rich source of big data to study medical and health care questions, but patient eligibility and preferences may limit generalizability of findings. We therefore examined the representativeness of VA veterans by comparing veterans using VA healthcare services to those who do not.

METHODS

We analyzed data on 3051 veteran participants age ≥ 18 years in the 2019 National Health Interview Survey. Weighted logistic regression was used to model participant characteristics, health conditions, pain, and self-reported health by past year VA healthcare use and generate predicted marginal prevalences, which were used to calculate Cohen's d of group differences in absolute risk by past-year VA healthcare use.

RESULTS

Among veterans, 30.4% had past-year VA healthcare use. Veterans with lower income and members of racial/ethnic minority groups were more likely to report past-year VA healthcare use. Health conditions overrepresented in past-year VA healthcare users included chronic medical conditions (80.6% vs. 69.4%, d = 0.36), pain (78.9% vs. 65.9%; d = 0.35), mental distress (11.6% vs. 5.9%; d = 0.47), anxiety (10.8% vs. 4.1%; d = 0.67), and fair/poor self-reported health (27.9% vs. 18.0%; d = 0.40).

CONCLUSIONS

Heterogeneity in veteran sociodemographic and health characteristics was observed by past-year VA healthcare use. Researchers working with VA EHR data should consider how the patient selection process may relate to the exposures and outcomes under study. Statistical reweighting may be needed to generalize risk estimates from the VA EHR data to the overall veteran population.

Living Alone and Suicide Risk in the United States, 2008‒2019

Objectives. To evaluate the association between living alone and suicide and how it varies across sociodemographic characteristics. Methods. A nationally representative sample of adults from the 2008 American Community Survey (n = 3 310 000) was followed through 2019 for mortality. Cox models estimated hazard ratios of suicide across living arrangements (living alone or with others) at the time of the survey. Total and sociodemographically stratified models compared hazards of suicide of people living alone to people living with others. Results. Annual suicide rates per 100 000 person-years were 23.0 among adults living alone and 13.2 among adults living with others. The age-, sex-, and race/ethnicity-adjusted hazard ratio of suicide for living alone was 1.75 (95% confidence interval = 1.64, 1.87). Adjusted hazards of suicide associated with living alone varied across sociodemographic groups and were highest for adults with 4-year college degrees and annual incomes greater than $125 000 and lowest for Black individuals. Conclusions. Living alone is a risk marker for suicide with the strongest associations for adults with the highest levels of income and education. Because these associations were not controlled for psychiatric disorders, they should be interpreted as noncausal. (Am J Public Health. 2022;112(12):1774-1782. https://doi.org/10.2105/AJPH.2022.307080).

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.

Sleep disturbance and suicide risk among sexual and gender minority people

Sleep disturbance has emerged as an independent, mechanistic, and modifiable risk factor for suicide. Sexual and gender minority (SGM) people disproportionately experience sleep disturbance and are at higher risk of death by suicide relative to cisgender and/or heterosexual individuals. The present narrative review evaluates nascent research related to sleep disturbance and suicide-related thoughts and behaviors (STBs) among SGM populations, and discusses how experiences of minority stress may explain heightened risk among SGM people. Although there is a growing understanding of the link between sleep disturbance and STBs, most research has not been conducted in SGM populations or has not examined suicide as an outcome. Research is needed to examine whether and how aspects of sleep disturbances relate to STBs among SGM people in order to better tailor sleep treatments for SGM populations.

Substance use disorders and COVID-19: An analysis of nation-wide Veterans Health Administration electronic health records

BACKGROUND

Substance use disorders (SUD) elevate the risk for COVID-19 hospitalization, but studies are inconsistent on the relationship of SUD to COVID-19 mortality.

METHODS

Veterans Health Administration (VHA) patients treated in 2019 and evaluated in 2020 for COVID-19 (n=5,556,315), of whom 62,303 (1.1%) tested positive for COVID-19 (COVID-19+). Outcomes were COVID-19+ by 11/01/20, hospitalization, ICU admission, or death within 60 days of a positive test. Main predictors were any ICD-10-CM SUDs, with substance-specific SUDs (cannabis, cocaine, opioid, stimulant, sedative) explored individually. Logistic regression produced unadjusted and covariate-adjusted odds ratios (OR; aOR).

RESULTS

Among COVID-19+ patients, 19.25% were hospitalized, 7.71% admitted to ICU, and 5.84% died. In unadjusted models, any SUD and all substance-specific SUDs except cannabis use disorder were associated with COVID-19+(ORs=1.06-1.85); adjusted models produced similar results. Any SUD and all substance-specific SUDs were associated with hospitalization (aORs: 1.24-1.91). Any SUD, cocaine and opioid disorder were associated with ICU admission in unadjusted but not adjusted models. Any SUD, cannabis, cocaine, and stimulant disorders were inversely associated with mortality in unadjusted models (OR=0.27-0.46). After adjustment, associations with mortality were no longer significant. In ad hoc analyses, adjusted odds of mortality were lower among the 49.9% of COVID-19+ patients with SUD who had SUD treatment in 2019, but not among those without such treatment.

CONCLUSIONS

In VHA patients, SUDs are associated with COVID-19 hospitalization but not COVID-19 mortality. SUD treatment may provide closer monitoring of care, ensuring that these patients received needed medical attention, enabling them to ultimately survive serious illness.

Suicidality Among Sexual Minority Adults: Gender, Age, and Race/Ethnicity Differences

INTRODUCTION

Lesbian, gay, and bisexual individuals have elevated suicide risk, but there is little information available about how this risk may vary by gender, age, and race/ethnicity.

METHODS

This study examined past-year suicide thoughts, plans, and attempts among adult respondents to the 2015-2019 National Surveys on Drug Use and Health (pooled N=191,954). Logistic regression was used to examine the differences between lesbian, gay, and bisexual and heterosexual adults for each outcome, once by gender and age category and once by gender and race/ethnicity category, while controlling for core sociodemographic characteristics. Race/ethnicity and age differences were also estimated within sexual identity groups.

RESULTS

Suicide thoughts, plans, and attempts were more common among lesbian, gay, and bisexual adults in almost every age and race/ethnicity category relative to that among corresponding heterosexual adults. In some age and race/ethnicity categories, bisexual women were more likely to report suicidal thoughts than lesbian/gay women. Each outcome decreased significantly across age groups among women of all sexual identity groups and heterosexual men; yet, this age effect was less pronounced among gay and bisexual men. Black women had significantly lower rates of suicidal thoughts and plans than White women in all sexual identity groups.

CONCLUSIONS

In light of consistently elevated rates of suicide thoughts and behaviors, lesbian, gay, and bisexual adults may expressly benefit from enhanced prevention, identification, and treatment of suicide risk. Additional research is needed to assess the associations between sexual identity and suicide mortality as well as to understand the heterogeneity in suicide risk among lesbian, gay, and bisexual youth, particularly by race/ethnicity.

Examining differences in suicidality between and within mental health disorders and sexual identity among adults in the United States

BACKGROUND

Suicide is a leading but preventable cause of death and is preceded by domains of thoughts, plans, and attempts. We assessed the prevalence of suicidality domains and determined the association of suicidality domains with sexual identity, mental health disorder symptoms, and sociodemographic characteristics.

METHODS

We used the 2019 National Survey on Drug Use and Health (NSDUH) data to perform weighted multivariable logistic regression and margins analyses to examine between and within-group differences in suicidality by sexual identity among adults aged ≥ 18 years.

RESULTS

About 4.89%, 1.37%, and 0.56% of the population experienced suicidal thoughts, plans, and attempts, respectively. Those aged 18-25 years old had a higher odds of suicidality compared to those aged 26 years or older. Compared to those who reported having no alcohol use dependence, illicit drug use dependence, and major depressive episodes (MDEs), those who reported alcohol use dependence, illicit drug use dependence, and MDE had higher odds of suicidal thoughts, plans, and attempts. Between all sexual identity groups, bisexuals who experienced MDEs had the highest probability of having suicidal thoughts while lesbians and gays who experienced MDE showed a higher probability of suicidal plans and attempts compared to heterosexuals. Within each sexual identity group, the probability of having suicidal thoughts, suicidal plans, and suicidal attempts was higher for those who had experienced MDEs compared to those who had not experienced MDEs.

CONCLUSION

Substance use disorder and MDE symptoms were associated with increased suicidality, especially among young adults and sexual minority people. This disparity underscores the need for tailored interventions and policies to enhance the provision of prompt mental health screening, diagnosis, and linkage to care for mental health services, particularly among the most vulnerable in the population.
