The present study evaluated sociodemographic and diagnostic predictors of suicidal ideation and attempts in a nationally representative sample of preadolescent youth enrolled in the Adolescent Brain Cognitive Development Study. Rates and predictors of psychiatric treatment utilization among suicidal youth also were examined. Eleven thousand eight hundred and seventy-five 9- and 10-year-old children residing in the United States were assessed. Children and their parents/guardians provided reports of children’s lifetime history of suicidal ideation, suicide attempts, and psychiatric disorders. Parents also reported on sociodemographic characteristics and mental health service utilization. Multivariate logistic regression analyses were employed to evaluate sociodemographic and diagnostic correlates of suicidal ideation, suicide attempts among youth with suicidal ideation, and treatment utilization among youth with suicidal ideation and suicide attempts. Lifetime prevalence rates were 14.33% for suicidal ideation and 1.26% for suicide attempts. Youth who identified as male, a sexual minority, or multiracial had greater odds of suicidal ideation, and sexual minority youth and youth with a low family income had greater odds of suicide attempts. Comorbid psychopathology was associated with higher odds of both suicidal ideation and suicide attempts. In youth, 34.59% who have suicidal ideation and 54.82% who had attempted suicide received psychiatric treatment. Treatment utilization among suicidal youth was lower among those who identified as female, Black, and Hispanic. Suicidal ideation and attempts among preadolescent children are concerningly high and targeted assessment and preventative efforts are needed, especially for males, racial, ethnic, and sexual minority youth, and those youth experiencing comorbidity.

本研究评估了参加青少年大脑认知发展研究的青春期前青年的全国代表性样本中自杀意念和企图的社会人口学和诊断预测因素。还检查了自杀青年中精神病治疗利用的比率和预测因素。对居住在美国的 11875 名 9 岁和 10 岁儿童进行了评估。儿童及其父母/监护人提供了儿童自杀意念、自杀企图和精神疾病的终生史报告。家长还报告了社会人口学特征和心理健康服务的利用情况。多变量逻辑回归分析用于评估自杀意念的社会人口统计学和诊断相关性，有自杀意念青少年的自杀企图，以及有自杀意念和自杀未遂青少年的治疗利用情况。自杀意念的终生患病率为 14.33%，自杀未遂为 1.26%。被认定为男性、性少数或多种族的青年有更大的自杀意念，性少数青年和家庭收入低的青年有更大的自杀企图。共病精神病理学与更高的自杀意念和自杀企图几率有关。在青年时期，34.59% 的有自杀意念的人和 54.82% 的曾试图自杀的人接受了精神治疗。在那些被认定为女性、黑人和西班牙裔的年轻人中，自杀青年的治疗利用率较低。
