Abstract

Background:  It is of great significance to identify relevant risk factors at all stages prior to a completed suicide and implement intervention measures in the early stage. This study adopted a longitudinal research design to analyze the association between the sleep chronotype of middle school students and suicidal psychological behaviors,  to provide a scientific basis for the prevention and control of suicide among middle school students.

Methods: In October 2021 and November 2022, a multi-stage cluster sampling method was used to conduct baseline and follow-up surveys in Shenyang, Zhengzhou, Nanchang and Taiyuan cities in China, and a total of 6 656 middle and high school students were included as the research subjects.The Chi-squre test was used to analyze the groups differences, and generalized estimating equations were used to analyze the associations between middle school student’s sleep chronotype and suicide ideation, suicide plan and suicide attempt, and the grade stratification was carried out.

Conclusion: There is a positive association between evening sleep chronotype and middle school students suicidal psychological behaviors, and improving sleep chronotype may be one of the effective measures to prevent middle school students suicide.

摘要

背景:在完成自杀前的各阶段进行早期识别相关危险因素并施加干预措施具有重要意义。本研究采用纵向研究设计,分析中学生睡眠时型与自杀相关心理行为的关联,为预防和控制中学生自杀提供科学依据。

方法:2021年10月和2022年11月,采用多阶段整群抽样方法在中国沈阳市、郑州市、南昌市、太原市进行基线和随访调查,共纳入6 656名初、高学生为研究对象。采用c2检验进行组间差异分析,采用广义估计方程分析中学生睡眠时型与自杀意念、自杀计划、自杀未遂的关联,并进行年龄分层。

结果:中学生基线自杀意念、自杀计划和自杀未遂的检出率分别26.3%、12.6%和5.3%;随访各项检出率分别21.0%、10.0%和4.8%。基线及随访中不同性别、学习负担,是否吸烟、饮酒,有无焦虑症状、抑郁症状的中学生自杀意念、自杀计划、自杀未遂检出率的差异均具有统计学意义(c2 =11.93~880.20,P值均<0.05)。调整性别、学习负担、体力活动、吸烟、饮酒、焦虑症状和抑郁症状等因素后,广义估计方程结果显示,夜晚型较清晨型睡眠时型的中学生自杀意念、自杀计划和自杀未遂的OR值(95%CI)分别为1.61(1.36~1.89),1.66(1.35~2.05)和1.41(1.06~1.88)(P值均<0.05),年级分层结果后与总体基本一致,初中生与高中生的夜晚型睡眠时型相较清晨型睡眠时型的自杀意念、自杀计划的风险更高[OR值(95%CI)分别为1.78(1.39~2.27),2.00(1.48~2.69);1.84(1.44~2.35),1.67(1.20~2.33),P值均<0.01]。

结论:夜晚型睡眠时型与中学生自杀心理行为存在正向关联,改善睡眠时型可能是预防中学生自杀的有效措施之一。
