Few studies are conducted to explore the longitudinal relationships between sleep situations and mental health among adolecents. This study aimed to explore the sleep situations (ie, sleep habits and sleep problems) among Chinese adolescents and the longitudinal associations between sleep situations and mental disorder symptoms (ie, depressive and anxiety symptoms).
This longitudinal study included 1957 high school students from ten schools in Guangzhou in January 2019, with 1836 students contributing valid data at a one-year follow-up (retention rate: 93.9%). Data of depressive and anxiety symptoms, sleep habits, and sleep problems were collected using a self-reported questionnaire.
The current study found that over half of the adolescents did not reach the recommended 8-h sleep-time on weekdays (63.3%). Short sleep duration, especially on weekdays, was significantly associated with subsequent depressive (AOR = 0.86, 95%CI: 0.80-0.92) and anxiety symptoms (AOR = 0.86, 95%CI: 0.77-0.96). In addition, longer weekday-weekend catch-up sleep and more sleep problems were risk factors of depressive and anxiety symptoms.
The health effects of insufficient sleep and suboptimal sleep quality on adolescents should not be neglected. Our longitudinal research showed that adolescents would demonstrate severer depressive and anxiety symptoms if lacking of a healthy sleeping practice. A regular sleep schedule and close attention to adolescents' mental disorders are highly recommended.
很少有研究探讨青少年睡眠状况与心理健康之间的纵向关系。本研究旨在探讨中国青少年的睡眠状况（即睡眠习惯和睡眠问题），以及睡眠状况与精神障碍症状（即抑郁和焦虑症状）之间的纵向关联。
这是一项纵向研究，纳入了 2019 年 1 月来自广州十所学校的 1957 名高中生，其中 1836 名学生在一年的随访中提供了有效数据（保留率：93.9%）。使用自报问卷收集抑郁和焦虑症状、睡眠习惯和睡眠问题的数据。
本研究发现，超过一半的青少年在工作日没有达到建议的 8 小时睡眠时间（63.3%）。睡眠时间短，尤其是在工作日，与随后的抑郁（AOR=0.86，95%CI：0.80-0.92）和焦虑症状（AOR=0.86，95%CI：0.77-0.96）显著相关。此外，工作日-周末补觉时间较长和更多的睡眠问题是抑郁和焦虑症状的危险因素。
青少年睡眠不足和睡眠质量不佳对健康的影响不容忽视。我们的纵向研究表明，如果青少年缺乏健康的睡眠习惯，他们会表现出更严重的抑郁和焦虑症状。建议制定规律的睡眠时间表并密切关注青少年的精神障碍。
