Abstract Study objectives: The present study evaluated the efficacy of sleep promotion program (SPP) on sleep hygiene practices, sleep quality, daytime sleepiness, and present functioning among adolescents. Methods: A two-arm, parallel, cluster randomized controlled trial was adopted. Participants were 660 adolescents aged 11–17(330 each in the intervention and control group). A socio-demographic questionnaire with sleep and activity items along with standardized questionnaires was used. Results: Significant improvements were observed in the experimental group after the intervention in the sleep hygiene practices, overall sleep quality and its sub-components like subjective sleep quality, sleep latency, and sleep efficiency at 2 weeks, and daytime sleepiness at 6 weeks. Other sleep quality components such as sleep duration, sleep disturbance, daytime dysfunction, and the present functioning compared did not statistically differ from the control group. Statistically significant positive correlations were observed between the target sleep variables. Sleep hygiene tends to deteriorate with higher grade level of adolescents, whereas sleep quality, sleep duration, and daytime sleepiness became worse with higher age and grade level. Conclusions: SPP holds a promise for improving healthy adolescents sleep behaviors. Interventions to improve emotional health could be explored in the future.

改善部分学校青少年睡眠行为的睡眠促进计划：一项随机对照试验

摘要研究目的：本研究评估了睡眠促进计划（SPP）对青少年睡眠卫生习惯，睡眠质量，白天嗜睡和当前功能的功效。方法：采用两臂，平行，集群随机对照试验。参与者为660名11-17岁的青少年（干预组和对照组各330名）。使用了带有睡眠和活动项目的社会人口统计学问卷以及标准化问卷。结果：在干预睡眠卫生习惯，总体睡眠质量及其子成分（如主观睡眠质量，睡眠潜伏期和第2周的睡眠效率以及第6周的白天嗜睡）后，实验组观察到了显着改善。其他睡眠质量要素，例如睡眠时间，睡眠障碍，白天的功能障碍和目前的功能比较与对照组无统计学差异。在目标睡眠变量之间观察到统计学上显着的正相关。青少年的年级越高，睡眠卫生就越容易恶化，而年龄和年级越高，睡眠质量，睡眠时间和白天嗜睡则越差。结论：SPP有望改善青少年健康的睡眠行为。将来可以探索改善情绪健康的干预措施。随着年龄和等级的提高，睡眠时间和白天嗜睡情况变得更糟。结论：SPP有望改善健康的青少年睡眠行为。将来可以探索改善情绪健康的干预措施。随着年龄和等级的提高，睡眠时间和白天嗜睡情况变得更糟。结论：SPP有望改善青少年健康的睡眠行为。将来可以探索改善情绪健康的干预措施。
