研究目的：青少年人群中的自杀是一种可悲的、可预防的死亡原因。先前的研究已经证实，在成年人中，总睡眠时间(TST)的长短都与自杀意念有关。方法：我们使用2007年和2009年的青少年危险行为调查对这一假设进行了检验，该调查包括以学校为基础的、具有全国代表性的样本(2007年的N=12,154,2009年的N=14,782)。在调整了年龄、性别、种族/民族、悲伤感觉和药物滥用等混杂因素后，采用Logistic回归模型评估自杀与睡眠的关系。结果：在全部样本中，大约15%的人报告有自杀念头，10%的人计划自杀，5%的人试图自杀，2%的人报告试图自杀需要治疗。报告睡眠时间为10小时的青少年发生自杀的风险显著高于睡眠时间为8小时的青少年。最严重的自杀形式(企图需要治疗)的优势比最大，当睡眠时间=10小时时，优势比为5.9。结论：睡眠时间短和时间长都是青少年自杀的危险因素，睡眠时间越长自杀倾向越严重。自我报告的睡眠时间可能是一个有用的自杀风险筛查问题。未来的研究应该检查睡眠时间是否是青少年自杀的一个因果和/或可改变的危险因素。
Study Objectives: Suicide in the adolescent population is a tragic and preventable cause of death. Previous studies have confirmed both long and short total sleep times (TSTs) are associated with suicidal ideation in the adult population. We hypothesized that both long and short TSTs are risk factors for serious suicide attempt in the adolescent population as well.Methods: We tested this hypothesis using the Youth Risk Behavior Surveys from 2007 and 2009, which consist of school-based, nationally representative samples (N = 12,154 for 2007, N = 14,782 for 2009). Logistic regression models were used to assess the relationship between suicidality and sleep after adjusting for confounders including age, sex, race/ethnicity, feelings of sadness, and substance abuse.Results: Of the total sample, roughly 15% reported suicidal ideation, 10% planned suicide, 5% attempted and 2% reported an attempt requiring treatment. Teens who reported sleeping = 10 h had a significantly higher risk for suicidality compared to those with a TST of 8 h. The largest odds ratios were found among the most severe forms of suicidality (attempt requiring treatment) with an odds ratio of 5.9 for a TST = 10 h.Conclusion: Both short and long TSTs are risk factors for suicidality among teens and extremes in TST may indicate more serious suicidality. Self-reported sleep duration may be a useful screening question for suicide risk. Future studies should examine whether sleep duration is a causal and/or modifiable risk factor for suicidality in teens.
