Insufficient sleep on weekdays among adolescents and its negative effects on mental health is a concerning public health issue. This study examined the relationship between weekday sleep duration, weekend compensatory sleep (WCS), and psychotic-like experiences (PLEs) in a large sample of Chinese adolescents.
A total of 39,731 junior high school students were recruited in this cross-sectional study. A self-report questionnaire was used to assess sleep duration, social-demographical characteristics, anxiety and depressive symptoms, and PLEs. Logistic regression and stratified analysis were performed to explore the associations between WCS and PLEs.
The prevalence of current PLEs was 12.4 % in this study. The average weekday sleep duration among adolescents was 7.7 ± 1.0 h. 93.2 % of participants reported WCS, with an average duration of 1.8 ± 1.6 h. WCS was significantly associated with a lower risk of PLEs (OR = 0.79, 95 % CI: 0.70-0.90). Moreover, 0-2 h of WCS was linked to a reduced risk of PLEs, regardless of whether students with weekday sleep duration <8 h (OR = 0.74, 95 % CI: 0.61-0.91) or ≥8 h (OR = 0.69, 95 % CI: 0.57-0.82). However, the significant role of WCS >2 h against PLEs was observed only among adolescents with weekday sleep duration <8 h (OR = 0.79, 95 % CI: 0.65-0.97).
WCS was associated with a lower risk of PLEs in adolescents, particularly those with insufficient weekday sleep. These findings highlight the importance of sufficient sleep and the potential benefits of compensatory sleep on adolescents' mental health.
青少年工作日睡眠不足及其对心理健康的负面影响是一个令人担忧的公共卫生问题。本研究在大量中国青少年样本中考察了工作日睡眠时间、周末补偿性睡眠（WCS）与类精神病体验（PLEs）之间的关系。
本横断面研究共招募了39731名初中生。采用自填式问卷评估睡眠时间、社会人口学特征、焦虑和抑郁症状以及PLEs。进行逻辑回归和分层分析以探讨WCS与PLEs之间的关联。
本研究中当前PLEs的患病率为12.4%。青少年工作日平均睡眠时间为7.7±1.0小时。93.2%的参与者报告有WCS，平均时长为1.8±1.6小时。WCS与较低的PLEs风险显著相关（OR=0.79，95%CI：0.70-0.90）。此外，无论工作日睡眠时间<8小时（OR=0.74，95%CI：0.61-0.91）还是≥8小时（OR=0.69，95%CI：0.57-0.82）的学生，0-2小时的WCS都与PLEs风险降低有关。然而，仅在工作日睡眠时间<8小时的青少年中观察到WCS>2小时对PLEs有显著作用（OR=0.79，95%CI：0.65-0.97）。
WCS与青少年较低的PLEs风险相关，尤其是那些工作日睡眠不足的青少年。这些发现凸显了充足睡眠的重要性以及补偿性睡眠对青少年心理健康的潜在益处。
