Mediating role of stressful life events between sleep chronotype and depressive mood in adolescents

摘要

摘要: 目的使用纵向中介模型探究应激性生活事件作为中介变量时，睡眠时型与抑郁情绪之间的内在关联机制，为预防青少年抑郁情绪提供参考依据。方法在2022年3月(T1)和10月(T2)，以慕尼黑睡眠时型问卷(MCTQ)、青少年生活事件量表(ASLEC)和流调中心用抑郁量表(CES-D)为调查工具，对四川眉山某中学的初一、初二年级1 251名中学生进行追踪研究，共收集到2个时点的睡眠时型、应激性生活事件、抑郁情绪数据。结果在T1时青少年抑郁情绪检出率为22.5%，在T2时抑郁情绪检出率为27.0%；在同一时间点，睡眠时型、应激性生活事件以及抑郁情绪之间均呈正相关(r=0.06~0.69，P值均 < 0.05)。交叉滞后模型结果显示，早期的睡眠时型可以预测后期的抑郁情绪(β=0.53，P < 0.05)，早期的抑郁情绪也能够显著预测后期的睡眠时型(β=0.01，P < 0.01)；纵向中介模型分析表明，T1睡眠时型不仅可以直接影响T2抑郁情绪(直接效应值为1.421，95%CI=0.985~1.858)，还可以通过T2应激性生活事件的中介作用影响T2抑郁情绪(间接效应值为1.268，95%CI=0.810~1.726)(P值均 < 0.05)；尽管T1抑郁情绪可以直接预测T2睡眠时型(直接效应值为0.025，95%CI=0.017~0.032，P < 0.05)，但不能够通过T2应激性生活事件的部分中介作用预测T2睡眠时型(间接效应值为-0.001，95%CI=-0.006~0.004，P>0.05)。结论睡眠时型不仅可以直接纵向预测青少年的抑郁情绪，同时也能通过应激性生活事件的纵向中介作用间接影响青少年的抑郁情绪。青少年应养成早睡早起的生活习惯，并提高对应激性生活事件的应对能力，降低抑郁情绪的发生，提高心理健康水平。

Abstract: Objective A longitudinal mediating model was designed to explore the relationship between sleep chronotype and depressive mood with stressful life events as the mediating variable, so as to provide reference basis for preventing depression in adolescents. Methods From March (T1) to October (T2) 2022, the Munich Chronotype Questionnaire, and Adolescent Self-rating Life Events Checklist and Center for Epidemiologic Studies Depression Scale were administered in 1 251 middle school students in the first and second grades of a middle school in Meishan, Sichuan Province for a follow-up study. Two wave of date on sleep time type, stressful life events, and depressive moods were collected. Results At T1, the detection rate of depressive mood was 22.5% in adolescents but 27.0% at T2.At the same time point, there were significant positive correlations between chronotype, stressful life events and depressive mood (r=0.06-0.69, P < 0.05). Cross-lagged model results showed that early sleep chronotype could significantly predict later depressive mood (β=0.53, P < 0.05), and early depressive mood could significantly predict later sleep chronotype (β=0.01, P < 0.01). Longitudinal mediation model analysis showed that T1 sleep chronotype not only directly affected T2 depressive mood (direct effect value=1.421, 95%CI=0.985-1.858, P < 0.01), but also affect T2 depressive mood through the partial mediating effects of T2 stressful life events (indirect effect value=1.268, 95%CI=0.810-1.726, P < 0.05). Although T1 depressive mood was a direct predictor of T2 sleep chronotype (direct effect value=0.025, 95%CI=0.017-0.032), it was not a direct predictor of T2 sleep chronotype by partial intermediate action of T2 stressful life events (indirect effect value=-0.001, 95%CI=-0.006-0.004, P>0.05). Conclusions Sleep chronotype can not only directly predict depressive mood of adolescents, but also indirectly affect depressive mood of adolescents through the longitudinal mediating effect of stressful life events. To prevent depression and improve mental health in this population, adolescents should develop the habit of early sleep schedule, and improve their ability to cope with stressful life events.
