To explore the mediating role of sleep duration in the relationship between depression symptoms and myopia among middle school students.
This study was a cross-sectional research conducted using a stratified cluster random sampling method. A total of 1 728 middle school students were selected from two junior high schools and two senior high schools in certain urban areas and farms of the Xinjiang Production and Construction Corps. Questionnaire surveys and vision tests were conducted among the students. Spearman analysis was used to analyze the correlation between depression symptoms, sleep duration, and myopia. The Bootstrap method was employed to investigate the mediating effect of sleep duration between depression symptoms and myopia.
The prevalence of myopia in the overall population was 74.02% (1 279/1 728), with an average sleep duration of (7.6±1.0) hours. The rate of insufficient sleep was 83.62% (1 445/1 728), and the proportion of students exhibiting depression symptoms was 25.29% (437/1 728). Correlation analysis showed significant negative correlations between visual acuity in both eyes and sleep duration with depressive emotions as measured by the Center for Epidemiologic Studies Depression Scale (with correlation coefficients of -0.064, -0.084, and -0.199 respectively; <0.01), as well as with somatic symptoms and activities (with correlation coefficients of -0.104, -0.124, and -0.233 respectively; <0.01) and interpersonal relationships (with correlation coefficients of -0.052, -0.059, and -0.071 respectively; <0.05). The correlation coefficients for left and right eye visual acuity and sleep duration were 0.206 and 0.211 respectively (<0.001). Sleep duration exhibited a mediating effect between depression symptoms and myopia (indirect effect=0.056, 95%: 0.029-0.088), with the mediating effect value for females (indirect effect=0.066, 95%: 0.024-0.119) being higher than that for males (indirect effect=0.042, 95%: 0.011-0.081).
Sleep duration serves as a partial mediator between depression symptoms and myopia in middle school students.
探讨睡眠时间在中学生抑郁症状与近视关系中的中介作用。
本研究采用分层整群随机抽样方法进行横断面研究。从新疆生产建设兵团某市区和农场的两所初中和两所高中选取了1728名中学生。对学生进行问卷调查和视力测试。采用Spearman分析抑郁症状、睡眠时间和近视之间的相关性。采用Bootstrap法研究睡眠时间在抑郁症状与近视之间的中介作用。
总体近视患病率为74.02%(1279/1728),平均睡眠时间为(7.6±1.0)小时。睡眠不足率为83.62%(1445/1728),出现抑郁症状的学生比例为25.29%(437/1728)。相关分析显示,双眼视力和睡眠时间与流行病学研究中心抑郁量表测量的抑郁情绪之间存在显著负相关(相关系数分别为-0.064、-0.084和-0.199;P<0.01),与躯体症状及活动(相关系数分别为-0.104、-0.124和-0.233;P<0.01)以及人际关系(相关系数分别为-0.052、-0.059和-0.071;P<0.05)之间也存在显著负相关。左眼和右眼视力与睡眠时间的相关系数分别为0.206和0.211(P<0.001)。睡眠时间在抑郁症状与近视之间存在中介作用(间接效应=0.056,95%置信区间:0.029-0.088),女性的中介效应值(间接效应=0.066,95%置信区间:0.024-0.119)高于男性(间接效应=0.042,95%置信区间:0.011-0.081)。
睡眠时间是中学生抑郁症状与近视之间的部分中介因素。
