目的:自杀和非自杀性自伤(NSSI)是年轻人可预防的问题。自杀意念(SI),自杀计划(SP)和自杀企图(SA)与死亡密切相关。睡眠问题是自杀和NSSI的已知危险因素。本研究旨在探讨睡眠之间的关系,自杀和NSSI。
方法:研究对象为河南省城乡3,828名11-23岁的中学生和大学生。Sleep,自杀现象和NSSI通过应用自我报告问卷进行评估.卡方检验用于证明人口统计数据和睡眠变量。睡眠之间的相关性,使用二元逻辑回归对自杀率和NSSI进行了探索,同时用多元模型调整社会人口学特征。
结果:除睡眠中时间外的睡眠变量与自杀现象有关(P<0.05)。更大的社会时差(SJL)[≥2h(h)]与SI风险增加相关[赔率(OR)=1.72,95%置信区间(CI):1.40-2.11],SP(OR=2.10,95CI:1.59-2.79)和SA(OR=1.50,95CI:1.00-2.26)。患有SJL(≥2h)的非独生子女参与者SI(OR=1.75,95CI:1.41-2.18)和SP(OR=2.25,95CI:1.66-3.05)的几率显着增加。平均时间型与SI的相关性最强(OR=3.87,95CI:2.78-5.38),SP(OR=4.72,95CI:2.97-7.50),SA(OR=6.69,95CI:3.08-14.52)和NSSI(OR=1.39,95CI:1.02-1.90)。
结论:睡眠时间过长或过短,SJL,晚上时间型和其他睡眠异常(例如,日间功能障碍,低睡眠效率)与较高的SI患病率相关,SP和SA。此外,在年轻人中,晚上与NSSI显著相关。这些发现表明了评估和干预睡眠习惯以预防年轻人自杀和NSSI的重要性。
OBJECTIVE: Suicide and non-suicidal self-injury (
NSSI) are preventable concerns in young people. Suicidal ideation (SI), suicidal plans (SP) and suicidal attempt (SA) are closely related to death. Sleep problems are known risk factors for suicide and
NSSI. This study aimed to explore the relationship between sleep, suicidality and
NSSI.
METHODS: Participants were 3,828 middle school and college students aged 11-23 years from urban and rural areas of Henan Province. Sleep, suicidal phenomena and
NSSI were assessed by applying self-reported questionnaires. Chi-squared tests were utilized to demonstrate the demographic data and sleep variables. The correlation between sleep, suicidality and NSSI were explored by using binary logistic regression, while adjusting socio-demographic characteristics with multivariate models.
RESULTS: Sleep variables except mid-sleep time were related to suicidal phenomena (P < 0.05). Greater social jet lag (SJL) [≥ 2 h (h)] was associated with increased risk of SI [Odds ratios (OR) = 1.72, 95% confidence intervals (CI):1.40-2.11], SP (OR = 2.10, 95%CI:1.59-2.79) and SA (OR = 1.50, 95%CI:1.00-2.26). Non-only child participants with SJL (≥ 2 h) had significantly increased odds of SI (OR = 1.75, 95%CI: 1.41-2.18) and SP (OR = 2.25, 95%CI: 1.66-3.05). Eveningness chronotype had the strongest correlation with SI (OR = 3.87, 95%CI:2.78-5.38), SP (OR = 4.72, 95%CI:2.97-7.50), SA (OR = 6.69, 95%CI:3.08-14.52) and NSSI (OR = 1.39, 95%CI:1.02-1.90).
CONCLUSIONS: Overlong or short sleep duration, SJL, eveningness chronotype and other sleep abnormalities (e.g., daytime dysfunction, low sleep efficiency) were associated with a higher prevalence of SI, SP and SA. Additionally, eveningness was significantly correlated with
NSSI among young people. These findings suggested the importance of assessing and intervening in sleep habits to prevent suicide and NSSI in young people.
