This study examined the relationship between sexual orientation and suicide risk in a population-based sample of adolescents.
Participants were selected from a cross-sectional, statewide survey of junior and senior public high school students. All males (n = 212) and females (n = 182) who described themselves as bisexual/homosexual were compared with 336 gender-matched heterosexual respondents on three outcome measures: suicidal ideation, intent, and self-reported attempts. Logistic regression analyses were used to examine the association between sexual orientation and outcome measures with adjustment for demographic characteristics.
Suicide attempts were reported by 28. 1 % of bisexual/homosexual males, 20.5% of bisexual/homosexual females, 14.5% of heterosexual females, and 4.2% of heterosexual males. For males, but not females, bisexual/homosexual orientation was associated with suicidal intent (odds ratio [OR] = 3.61 95% confidence interval [CI = 1.40, 9.36) and attempts (OR=7.10; 95% CI=3.05, 16.53).
There is evidence of a strong association between suicide risk and bisexuality or homosexuality in males.
本研究在一个基于人群的青少年样本中，考察了性取向与自杀风险之间的关系。
参与者选自一项针对初中和高中公立学校学生的全州横断面调查。将所有自称双性恋/同性恋的男性（n = 212）和女性（n = 182）与336名性别匹配的异性恋受访者在三项结果指标上进行比较：自杀意念、自杀意图和自我报告的自杀未遂情况。采用逻辑回归分析来考察性取向与结果指标之间的关联，并对人口统计学特征进行了调整。
报告有自杀未遂情况的比例在双性恋/同性恋男性中为28.1%，双性恋/同性恋女性中为20.5%，异性恋女性中为14.5%，异性恋男性中为4.2%。对于男性而非女性，双性恋/同性恋取向与自杀意图（优势比[OR]=3.61；95%置信区间[CI]=1.40，9.36）和自杀未遂（OR=7.10；95%CI=3.05，16.53）相关。
有证据表明男性的自杀风险与双性恋或同性恋之间存在密切关联。
