Current evidence about the association between sleep and suicide are conflicting. This study aimed to investigate the association between sleep duration and quality with suicidal behaviors in a group of school-aged adolescents in China. The baseline survey was conducted among Chinese adolescents aged 12-13 years in October 2016. All participants were asked to complete a self-administered questionnaire. After 2 years follow-up, a total of 1513 adolescents completed the follow-up. The multivariable logistic regression analysis showed that shorter sleep duration (<8 h per night) in baseline was associated with an increased likelihood of suicidality in boys [suicidal ideation, adjusted odds ratio (OR)=2.18, 95% confidence interval (CI)=1.97 to 3.98; suicide planning, OR=2.47, 95% CI=1.22 to 5.01; suicide attempt, OR=2.97, 95% CI=1.39 to 6.38]. Similarly, poor sleep quality [Pittsburgh Sleep Quality Index (PSQI) ≧ 5] was associated with an increased likelihood of suicidal ideation and suicide planning in boys (OR=2.14, 95% CI=1.15 to 3.99 and OR=2.47, 95% CI=1.16 to 5.25, respectively). This study indicates that school-aged boys are more likely to experience suicidality in exposure to short sleep or poor sleep quality.
目前关于睡眠与自杀之间关联的证据相互矛盾。本研究旨在调查中国一组学龄期青少年中睡眠时长和睡眠质量与自杀行为之间的关联。基线调查于 2016 年 10 月在中国 12-13 岁青少年中进行。所有参与者都被要求完成一份自我管理的问卷。两年随访后，共有 1513 名青少年完成了随访。多变量逻辑回归分析显示，基线时睡眠时长较短（每晚<8 小时）与男孩自杀意念的可能性增加相关[自杀意念，调整后的优势比（OR）=2.18，95%置信区间（CI）=1.97 至 3.98；自杀计划，OR=2.47，95%CI=1.22 至 5.01；自杀尝试，OR=2.97，95%CI=1.39 至 6.38]。同样，睡眠质量差[匹兹堡睡眠质量指数（PSQI）≧5]与男孩自杀意念和自杀计划的可能性增加相关（OR=2.14，95%CI=1.15 至 3.99 和 OR=2.47，95%CI=1.16 至 5.25）。本研究表明，处于暴露状态的学龄期男孩更容易出现睡眠时长较短或睡眠质量较差的自杀意念和自杀计划。
