Research conducted over the past three decades finds that many children and adolescents do not meet recommended sleep guidelines. Lack of sleep is a predictor of a number of consequences, including issues at school such as sleepiness and tardiness. Considering the severity of this public health issue, it is essential to understand more about the factors that may compromise children's and adolescents' sleep. This meta-analysis examined the effects of school start time (SST) on sleep duration of students by aggregating the results of five longitudinal studies and 15 cross-sectional comparison group studies. Results indicated that later starting school times are associated with longer sleep durations. Additionally, later start times were associated with less daytime sleepiness (7 studies) and tardiness to school (3 studies). However, methodological considerations, such as a need for more longitudinal primary research, lead to a cautious interpretation. Overall, this systematic analysis of SST studies suggests that delaying SST is associated with benefits for students' sleep and, thus, their general well-being.
过去三十年来的研究发现，许多儿童和青少年不符合推荐的睡眠指南。睡眠不足是许多后果的预测因素，包括在学校出现困倦和迟到等问题。考虑到这一公共卫生问题的严重性，了解可能影响儿童和青少年睡眠的因素至关重要。本荟萃分析通过汇总五项纵向研究和 15 项横断面比较组研究的结果，考察了学校开始时间（SST）对学生睡眠时长的影响。结果表明，较晚的上学时间与较长的睡眠时间有关。此外，较晚的开始时间与白天困倦（7 项研究）和上学迟到（3 项研究）有关。然而，由于需要更多的纵向主要研究等方法学考虑因素，需要谨慎解释。总的来说，对 SST 研究的系统分析表明，延迟 SST 与学生睡眠质量提高有关，从而提高了他们的整体幸福感。
