OBJECTIVES Sexual minority adolescents have previously been found to experience disparities in self-injurious thoughts and behaviors (SITBs) compared to heterosexual adolescents. However, there is a paucity of data on SITBs amongst children. Thus, the aim of the current study is to assess the prevalence of SITBs in a large sample of U.S. children and to test whether rates vary by sexual orientation. METHODS Data were drawn from the 2.0 baseline release of the Adolescent Brain Cognitive Development (ABCD) study. The full sample included 11,777raw 9-10-year-old children (sexual minority n = 150raw). Children completed a computerized version of the youth Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS-5), including items assessing suicide ideation, suicide attempts, and nonsuicidal self-injury (NSSI). Unadjusted and adjusted models compared the prevalence of outcomes by sexual orientation. Models also compared the co-occurrence of NSSI and suicide ideation by sexual orientation. RESULTS Across all outcomes, sexual minority children reported elevated prevalence rates compared to heterosexual children, with odds ratios ranging from 4.4 to 6.5. Among children who reported NSSI, a greater proportion of sexual minority versus heterosexual children reported co-occurring suicide ideation (OR = 3.8). CONCLUSIONS In a large sample of 9-10-year-old U.S. children, sexual orientation disparities emerged across NSSI, suicide ideation, and suicide attempts. Results indicate that sexual minority children are a vulnerable population for SITBs. Inclusion of children in prevention programs is encouraged.

性少数儿童中的非自杀性自残，自杀意念和自杀未遂。

目标先前已经发现，与异性恋青少年相比，少数族裔青少年在自我伤害的思想和行为（SITB）方面存在差异。但是，儿童中关于SITB的数据很少。因此，本研究的目的是评估大量美国儿童中SITB的患病率，并检验其发生率是否因性取向而异。方法数据摘自青少年脑认知发育（ABCD）研究的2.0基线版本。完整样本包括11777名9-10岁的儿童（性少数n = 150raw）。孩子们完成了青少年情感障碍和精神分裂症儿童时间表（KSADS-5）的计算机版本，其中包括评估自杀观念，自杀企图和非自杀性自残（NSSI）的项目。未经调整和调整的模型通过性取向比较了结局患病率。模型还通过性取向比较了NSSI和自杀意念的同时出现。结果在所有结局中，与异性恋儿童相比，性少数族裔儿童的患病率有所上升，比值比在4.4到6.5之间。在报告了NSSI的儿童中，性少数和异性恋儿童中有较大比例的人报告了同时发生自杀意念（OR = 3.8）。结论在大量的9-10岁美国儿童样本中，NSSI，自杀观念和自杀企图之间出现了性取向差异。结果表明，性少数儿童是SITB的弱势群体。鼓励将儿童纳入预防方案。（PsycInfo数据库记录（c）2021 APA，
