Suicide continues to be the second-leading cause of death for all youths aged 15-24. Lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youth are at a significantly higher risk for suicidal thoughts or behaviors (STB). Establishing and understanding correlates of STB among LGBTQ youth is one important step toward enhancing prevention, intervention, and research efforts. To synthesize current knowledge on suicide among LGBTQ youth, the present meta-analyses offer results from 44 studies over the past 20 years. Two-hundred and thirty-four correlation coefficient effect sizes were calculated and categorized. To be included, the study had to quantitatively examine correlates of STB among LGBTQ youth. A number of social-science databases were used to examine the existing published research. Results illustrated the variability among correlates of STB as well as substantial limitations in the extant literature. There was a heterogeneity of effect sizes, a lack of novel correlates, a focus on risk, a dearth of theoretically driven designs, moderate publication bias, a paucity of developmentally driven analyses, and a dearth of research with transgender youth.
自杀仍然是所有 15-24 岁年轻人的第二大死因。女同性恋、男同性恋、双性恋、跨性别和疑问（LGBTQ）青年自杀念头或行为（STB）的风险显著更高。确定 LGBTQ 青年 STB 的相关因素并了解这些因素是加强预防、干预和研究工作的重要一步。为了综合 LGBTQ 青年自杀的现有知识，本次荟萃分析提供了过去 20 年 44 项研究的结果。计算并分类了 234 个相关系数效应大小。为了被纳入，研究必须定量检查 LGBTQ 青年 STB 的相关因素。使用了一些社会科学数据库来检查现有的已发表研究。结果说明了 STB 的相关因素的可变性，以及现有文献的重大局限性。存在效应大小的异质性、缺乏新颖的相关因素、对风险的关注、缺乏理论驱动的设计、中度出版偏见、发展驱动的分析不足以及缺乏跨性别青年的研究。
