Bedtime procrastination has been associated with poorer sleep health, but evidence for this association is not sufficient. This cross-sectional study aimed to investigate the relationship between bedtime procrastination and multidimensional sleep health among students at different educational stages (from elementary school to college) in China, and further examine the moderating role of psychological distress in the procrastination-sleep health link. A total of 3539 students (M = 15.6 [2.9] years) completed an online survey between December 17 and 31st, 2023. Sociodemographics, bedtime procrastination, chronotype, psychological distress, and sleep health indicators were assessed. Binary logistic regression was used to estimate the association of bedtime procrastination with sleep health. The moderating effects of psychological distress were examined using the Process macro. The results showed that, from elementary school to college, scores of bedtime procrastination displayed a gradually increasing trend. Greater bedtime procrastination across different educational stages was related to poorer sleep health, including satisfaction, alertness, timing, efficiency, and regularity. However, there was no significant association between bedtime procrastination and sleep duration among elementary, middle, and high school students. Moreover, the moderating effect of psychological distress was observed among middle and high school students. The negative association between bedtime procrastination and total sleep health was attenuated in students with high psychological distress than in students with low psychological distress. The findings underscore the importance of early prevention and intervention strategies targeting bedtime procrastination.
晚睡拖延与较差的睡眠健康状况有关，但这种关联的证据并不充分。这项横断面研究旨在调查中国不同教育阶段（从小学到大学）学生的晚睡拖延与多维度睡眠健康之间的关系，并进一步检验心理困扰在拖延与睡眠健康关联中的调节作用。共有3539名学生（平均年龄M = 15.6 [2.9]岁）在2023年12月17日至31日期间完成了一项在线调查。评估了社会人口统计学特征、晚睡拖延、昼夜节律类型、心理困扰和睡眠健康指标。采用二元逻辑回归来估计晚睡拖延与睡眠健康的关联。使用Process宏检验心理困扰的调节作用。结果显示，从小学到大学，晚睡拖延得分呈逐渐上升趋势。不同教育阶段中，更大程度的晚睡拖延与较差的睡眠健康有关，包括满意度、警觉性、时间安排、效率和规律性。然而，在小学、初中和高中学生中，晚睡拖延与睡眠时间之间没有显著关联。此外，在初中和高中学生中观察到了心理困扰的调节作用。与低心理困扰的学生相比，高心理困扰的学生中，晚睡拖延与总体睡眠健康之间的负相关减弱。这些发现强调了针对晚睡拖延的早期预防和干预策略的重要性。
