Despite strong indications of elevated risk of suicidal behavior in lesbian, gay, bisexual, and transgender people, limited attention has been given to research, interventions or suicide prevention programs targeting these populations. This article is a culmination of a three-year effort by an expert panel to address the need for better understanding of suicidal behavior and suicide risk in sexual minority populations, and stimulate the development of needed prevention strategies, interventions and policy changes. This article summarizes existing research findings, and makes recommendations for addressing knowledge gaps and applying current knowledge to relevant areas of suicide prevention practice.

AIMS Several decades of research have shown that lesbian, gay and bisexual (LGB) adults are at high risk for substance use and substance use disorders (SUDs). These problems may often start prior to young adulthood; however, relatively little is known about risk for substance use in LGB adolescents. The primary aims of this paper were to conduct a meta-analysis of the relationship between sexual orientation and adolescent substance use and a systematic review and critique of the methodological characteristics of this literature. METHODS Medical and social science journals were searched using Medline and PsychInfo. Studies were included if they tested the relationship between sexual orientation and adolescent substance use. Eighteen published studies were identified. Data analysis procedures followed expert guidelines, and used National Institutes of Health (NIH)-sponsored meta-analysis software. RESULTS LGB adolescents reported higher rates of substance use compared to heterosexual youth (overall odds ratio = 2.89, Cohens d = 0.59). Effect sizes varied by gender, bisexuality status, sexual orientation definition and recruitment source. None of the studies tested mediation and only one tested moderation. One employed a matched comparison group design, one used a longitudinal design, and very few controlled for possible confounding variables. CONCLUSIONS The odds of substance use for LGB youth were, on average, 190% higher than for heterosexual youth and substantially higher within some subpopulations of LGB youth (340% higher for bisexual youth, 400% higher for females). Causal mechanisms, protective factors and alternative explanations for this effect, as well as long-term substance use outcomes in LGB youth, remain largely unknown.

PURPOSE To examine disparities between sexual minority youth (SMY) and heterosexual youth in rates of suicidality and depression symptoms. METHODS Separate meta-analyses were conducted to examine suicidality and depression disparities. Studies were included if the average age of the participants was <18 years, and if suicidality or depression symptoms were compared across SMY and heterosexual youth. RESULTS SMY reported significantly higher rates of suicidality (odds ratio [OR] = 2.92) and depression symptoms (standardized mean difference, d = .33) as compared with the heterosexual youth. Disparities increased with the increase in the severity of suicidality (ideation [OR = 1.96], intent/plans [OR = 2.20], suicide attempts [OR = 3.18], suicide attempts requiring medical attention [OR = 4.17]). Effects did not vary across gender, recruitment source, and sexual orientation definition. CONCLUSIONS Disparities in suicidality and depression may be influenced by negative experiences including discrimination and victimization. Clinicians should assess sexual orientation, analyze psychosocial histories to identify associated risk factors, and promote prevention and intervention opportunities for SMY and their families.

OBJECTIVES We compared the likelihood of childhood sexual abuse (under age 18), parental physical abuse, and peer victimization based on sexual orientation. METHODS We conducted a meta-analysis of adolescent school-based studies that compared the likelihood of childhood abuse among sexual minorities vs sexual nonminorities. RESULTS Sexual minority individuals were on average 3.8, 1.2, 1.7, and 2.4 times more likely to experience sexual abuse, parental physical abuse, or assault at school or to miss school through fear, respectively. Moderation analysis showed that disparities between sexual minority and sexual nonminority individuals were larger for (1) males than females for sexual abuse, (2) females than males for assault at school, and (3) bisexual than gay and lesbian for both parental physical abuse and missing school through fear. Disparities did not change between the 1990s and the 2000s. CONCLUSIONS The higher rates of abuse experienced by sexual minority youths may be one of the driving mechanisms underlying higher rates of mental health problems, substance use, risky sexual behavior, and HIV reported by sexual minority adults.

Gay-related Development, Early Abuse and Adult Health Outcomes Among Gay Males

Mark S. Friedman; Michael P. Marshal; Ron Stall; JeeWon Cheong; Eric R. Wright

This study examined relationships between timing of gay-related developmental milestones, early abuse, and emergence of poor health outcomes in adulthood among 1,383 gay/bisexual men in the Urban Men’s Health Study. Latent Profile Analysis grouped participants as developing early, middle or late based on the achievement of four phenomena including age of first awareness of same-sex sexual attractions and disclosure of sexual orientation. Participants who developed early were more likely, compared to others, to experience forced sex and gay-related harassment before adulthood. They were more likely to be HIV seropositive and experience gay-related victimization, partner abuse and depression during adulthood. Early forced-sex, gay-related harassment and physical abuse were associated with several negative health outcomes in adulthood including HIV infection, partner abuse, and depression. This analysis suggests that the experience of homophobic attacks against young gay/bisexual male youth helps to explain heightened rates of serious health problems among adult gay men.

Men who have sex with men experience high rates of psychosocial health problems such as depression, substance use, and victimization that may be in part the result of adverse life experiences related to cultural marginalization and homophobia. These psychosocial health conditions interact to form a syndemic which may be driving HIV risk within this population. However, MSM also evidence great resilience to both the effects of adversity and the effects of syndemics. Investigating and harnessing these natural strengths and resiliencies may enhance HIV prevention and intervention programs thereby providing the additional effectiveness needed to reverse the trends in HIV infection among MSM.

Attempts to document changing HIV incidence rates among MSM are compromised by issues of generalizability and statistical power. To address these issues, this paper reports annualized mean HIV incidence rates from the entire published incidence literature on MSM from Europe, North America and Australia for the period 1995–2005. Publications that met the entry criteria were coded for region of the world, sampling method and year of study. From these reports, we calculated a mean incidence rate with confidence intervals for these variables. Although no differences in mean incidence rates were found for MSM from 1995 to 2005, HIV incidence rates are lower in Australia than either North America or Europe. We calculated a mean incidence rate of 2.39% for MSM in the United States, which if sustained within a cohort of MSM, would yield HIV prevalence rate of approximately 40% at age 40. These extrapolations overlap published HIV prevalence rates for MSM younger than age 40 in the United States. HIV incidence rates in the 2–3% range will adversely affect the health of gay male communities for decades to come. This analysis suggests that greater attention should be devoted to the question of how best to design prevention interventions that will lower HIV incidence rates among gay men.

Abstract Prior research suggests that the interconnections between substance use, HIV risk and lack of adherence to HIV medications are especially strong among homeless individuals. Thus, study of these interconnections warrants public health attention. The objectives of this paper are to describe patterns of alcohol and drug use, associations between substance use and participation in high-risk sex, and associations between substance use and adherence to HIV treatment regimens among a sample of 602 homeless or unstably housed HIV-seropositive individuals who are part of a housing-based intervention – the Housing and Health Study. Participants experienced high levels of substance use. Significant associations were found between substance use and adherence to HIV treatment medications, and between substance use and high-risk sexual practices within the entire group. Group analyses by sexual orientation/gender show that the association between substance use and treatment adherence is found primarily among heterosexual males whereas the relationship between several drugs and high-risk sexual practices is strongest among gay and bisexual men. Health professionals working with HIV-seropositive individuals should routinely ascertain housing status and screen for substance use and risky sex.

PURPOSE To examine disparities between sexual minority girls (SMGs) and heterosexual girls in trajectories of substance use over time. METHOD Girls were included in the analyses if they were 12-18 years of age at wave 1 and did not miss sexual orientation data at wave 4 (n = 7,765). Latent curve models were estimated across all four waves (extending from middle adolescence into young adulthood) to examine trajectories of cigarette and alcohol use. RESULTS Initial levels of substance use were higher for SMGs than they were for heterosexual girls. SMGs also exhibited sharper escalations in use across all substances over time as they were transitioning into young adulthood. CONCLUSIONS Persistent rates of cigarette and heavy alcohol use among SMGs may increase their risk for a host of mental and physical health problems in adulthood. Clinicians should be prepared to discuss SMG health topics effectively and in private, and discuss prevention and intervention programs with girls at risk.

PURPOSE To examine substance use and mental health disparities between sexual minority girls and heterosexual girls. METHODS Data from the Pittsburgh Girls Study were analyzed. All girls were 17 years old. Girls were included if they were not missing self-reported sexual orientation and mental health data (N = 527). Thirty-one girls (6%) endorsed same-sex romantic orientation/identity or current same-sex attraction. Bivariate analyses were conducted to test group differences in the prevalence of substance use and suicidal behavior, and group differences in depression, anxiety, borderline personality disorder (BPD), oppositional defiant disorder (ODD), and conduct disorder (CD) symptoms. RESULTS Compared with heterosexual girls, sexual minority girls reported higher past-year rates of cigarette, alcohol, and heavy alcohol use, higher rates of suicidal ideation and self-harm, and higher average depression, anxiety, BPD, ODD, and CD symptoms. CONCLUSIONS Sexual minority girls are an underrepresented group in the health disparities literature, and compared with heterosexual girls, they are at higher risk for mental health problems, most likely because of minority stress experiences such as discrimination and victimization. The disparities found in this report highlight the importance of discussing sexual orientation as part of a comprehensive preventive care visit.
