Estimating the Risk of Attempted Suicide Among Sexual Minority Youths

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. 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. 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]). 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.

Many reports have indicated that gay, lesbian and bisexual (GLB) youth are particularly vulnerable to poor outcomes, including suicide. Certain protective factors are likely to reduce this risk. The present study examines four protective factors (family connectedness, teacher caring, other adult caring, and school safety) and their association with suicidal ideation and attempts among adolescents with same-gender experience. Data come from the 2004 Minnesota Student Survey of 9th and 12th grade students; 21,927 sexually active youth were grouped according to the gender of their sex partner(s) into GLB and non-GLB groups. Four protective factors and suicidal ideation and attempts were compared across groups. Logistic regression was used to examine the influence of protective factors on suicide, and predicted probabilities of suicidal ideation and attempts were estimated using general linear modeling. There were 2,255 respondents who reported same-gender experience. Over half of GLB students had thought about suicide and 37.4% reported a suicide attempt. GLB youth reported significantly lower levels of each protective factor than their non-GLB peers. Family connectedness, adult caring, and school safety were significantly protective against suicidal ideation and attempts. Risk associated with a GLB sexual orientation is largely mediated through protective factors. Sexual orientation alone accounts for only a small portion of variability in suicidal ideation and attempts. If protective factors were enhanced among GLB youth, suicide in this population is expected to be considerably lower. Protective factors examined here are amenable to change and should be targeted in interventions.
