WHAT'S KNOWN ON THIS SUBJECT: Lesbian, gay, and bisexual (LGB) youth attempt suicide at significantly higher rates than heterosexuals. The social environment may contribute to this elevated risk, but few empirical studies have used objective measures of the social environment to examine this hypothesis.
WHAT THIS STUDY ADDS:This study demonstrated that negative characteristics of the social environment increase risk for suicide attempts among LGB youth, independent of individuallevel risk factors. These results suggest that identifying structural interventions may help to reduce sexual orientationrelated disparities in suicide attempts. abstract OBJECTIVE: To determine whether the social environment surrounding lesbian, gay, and bisexual youth may contribute to their higher rates of suicide attempts, controlling for individual-level risk factors.
METHODS:A total of 31 852 11th grade students (1413 [4.4%] lesbian, gay, and bisexual individuals) in Oregon completed the Oregon Healthy Teens survey in 2006 -2008. We created a composite index of the social environment in 34 counties, including (1) the proportion of same-sex couples, (2) the proportion of registered Democrats, (3) the presence of gay-straight alliances in schools, and (4) school policies (nondiscrimination and antibullying) that specifically protected lesbian, gay, and bisexual students.
RESULTS:Lesbian, gay, and bisexual youth were significantly more likely to attempt suicide in the previous 12 months, compared with heterosexuals (21.5% vs 4.2%). Among lesbian, gay, and bisexual youth, the risk of attempting suicide was 20% greater in unsupportive environments compared to supportive environments. A more supportive social environment was significantly associated with fewer suicide attempts, controlling for sociodemographic variables and multiple risk factors for suicide attempts, including depressive symptoms, binge drinking, peer victimization, and physical abuse by an adult (odds ratio: 0.97 [95% confidence interval: 0.96 -0.99]).
CONCLUSIONS:This study documents an association between an objective measure of the social environment and suicide attempts among lesbian, gay, and bisexual youth. The social environment appears to confer risk for suicide attempts over and above individual-level risk factors. These results have important implications for the development of policies and interventions to reduce sexual orientation-related disparities in suicide attempts.
