Sexual and gender minority populations are at elevated risk of experiencing suicidal thoughts and attempting suicide. The COVID-19 pandemic exacerbated mental health and substance use challenges among this population. We aimed to examine the relative importance and effects of intersectional factors and strong interactions associated with the risk of suicidal thoughts among Canadian lesbian, gay, bisexual, transgender, queer, questioning, intersex and Two Spirit (LGBTQI2S+) young adults. A cross-sectional online survey was conducted among LGBTQI2S + participants aged 16-29 years living in two Canadian provinces (Ontario, Quebec). Among 1414 participants (mean age 21.90 years), 61% (n = 857) participants reported suicidal thoughts in last 12 months. We built a random forest model to predict the risk of having past year suicidal thoughts, which achieved high performance with an area under the receiver operating characteristic curve (AUC) of 0.84. The top 10 correlates identified were: seeking help from health professionals for mental health or substance use issues since the start of the pandemic, current self-rated mental health status, insulted by parents or adults in childhood, ever heard that being identifying as LGBTQI2S+ is not normal, age in years, past week feeling depressed, lifetime diagnosis of mental illness, lifetime diagnosis of depressive disorder, past week feeling sad, ever pretended to be straight or cisgender to be accepted. The increase in the risk of suicidal thoughts for those having mental health challenges or facing minority stressors is more pronounced in those living in urban areas or being unemployed than those living in rural areas or being employed.
性少数群体和跨性别群体经历自杀念头和自杀企图的风险较高。COVID-19 大流行加剧了该人群的心理健康和药物使用挑战。我们旨在研究与加拿大女同性恋、男同性恋、双性恋、跨性别、酷儿、疑问、间性人和双灵（LGBTQI2S+）青年成年人自杀念头风险相关的交叉因素和强交互作用的相对重要性和影响。在两个加拿大省份（安大略省和魁北克省），对 16-29 岁的 LGBTQI2S+参与者进行了一项横断面在线调查。在 1414 名参与者中（平均年龄 21.90 岁），61%（n=857）参与者报告在过去 12 个月中有自杀念头。我们构建了一个随机森林模型来预测过去一年有自杀念头的风险，该模型的接收者操作特征曲线（AUC）下面积达到 0.84，性能很高。确定的前 10 个相关因素为：自大流行开始以来，因心理健康或药物使用问题向卫生专业人员寻求帮助、当前自我评估的心理健康状况、在童年时期受到父母或成年人的侮辱、曾经听说过认同为 LGBTQI2S+是不正常的、年龄、过去一周感到抑郁、终身诊断患有精神疾病、终身诊断患有抑郁症、过去一周感到悲伤、曾经为了被接受而假装直或顺性别。与生活在农村地区或有工作的人相比，生活在城市地区或失业的人，心理健康有问题或面临少数群体压力的人自杀念头风险增加更为明显。
