To compare risk of suicide ideation and attempts in adolescents with 1) gay, lesbian, or bisexual (GLB) identity, 2) "unsure" identity, or 3) heterosexual identity with same-sex attraction/fantasy or behavior, to heterosexual identity without same-sex attraction/fantasy or behavior.
A total of 1,856 students 14 years of age and older from 14 public and private high schools in Montréal, Québec, were surveyed anonymously. The survey included items assessing sexual orientation, health risk behaviors, and suicidal ideation and attempts. Multiple logistic regression models were used to assess risk factors for suicidal ideation and attempts.
In all, 58 (3.1%) adolescents self-identified as GLB, 59 (3.2%) as unsure, and 115 (6.2%) as heterosexual with same-sex attraction/fantasy or behavior. Compared with heterosexually identified youth without same-sex attraction/fantasy or behavior (N = 1,624; 87.5%), in multivariable analyses, 12-month suicidal ideation was significantly higher for both GLB (odds ratio [OR] = 2.31, 95% confidence interval [CI] = 1.22-4.37) and unsure youth (OR = 2.64, 95% CI = 1.38-5.08). Twelve-month suicide attempts were significantly elevated for GLB youth (OR = 2.23, 95% CI = 1.15-4.35) and high, although not statistically significant, for unsure youth (OR = 1.61, 95% CI = 0.77-3.36). Heterosexual identity with same-sex attraction/fantasy or behavior was not significantly associated with increased suicidal ideation (OR = 1.26, 95% CI = 0.76-2.08) or attempts (OR = 1.03, 95% CI = 0.55-1.91) in multivariable analyses.
Compared with heterosexual youth without same-sex attraction/fantasy or behavior, adolescents with GLB and unsure identities were at greater risk of suicidality. However, youth who reported same-sex attraction or behavior but a heterosexual identity were not at elevated risk.
比较具有 1）同性恋、双性恋或双性恋（GLB）身份、2）“不确定”身份或 3）与同性吸引/幻想或行为有相同性取向的异性恋身份的青少年与具有同性吸引/幻想或行为的异性恋身份的自杀意念和尝试的风险。
对来自魁北克省蒙特利尔市 14 所公立和私立高中的 1856 名 14 岁及以上的学生进行了匿名调查。该调查包括评估性取向、健康风险行为以及自杀意念和尝试的项目。多变量逻辑回归模型用于评估自杀意念和尝试的危险因素。
共有 58 名（3.1%）青少年自我认同为 GLB，59 名（3.2%）不确定，115 名（6.2%）为与同性吸引/幻想或行为有相同性取向的异性恋。与没有同性吸引/幻想或行为的异性恋身份的青年相比（N=1624；87.5%），在多变量分析中，GLB 青少年（OR=2.31，95%CI=1.22-4.37）和不确定青少年（OR=2.64，95%CI=1.38-5.08）的 12 个月自杀意念率显著升高。GLB 青少年的 12 个月自杀企图率显著升高（OR=2.23，95%CI=1.15-4.35），不确定青少年的自杀企图率虽然不显著升高，但仍较高（OR=1.61，95%CI=0.77-3.36）。具有同性吸引/幻想或行为的异性恋身份与自杀意念（OR=1.26，95%CI=0.76-2.08）或企图（OR=1.03，95%CI=0.55-1.91）的增加均无显著相关性。
与没有同性吸引/幻想或行为的异性恋青年相比，具有 GLB 和不确定身份的青少年自杀的风险更高。然而，报告同性吸引或行为但具有异性恋身份的青少年没有处于更高的风险中。
