儿童时期充足的睡眠对于确保过渡到健康的成年期至关重要。然而，慢性睡眠损失在全球范围内继续增加。在这方面，必须把睡眠作为高度优先事项，并采取行动促进儿童的睡眠健康。本系列研究旨在阐明睡眠模式、睡眠与学习成绩的纵向关联，以及对中国学龄儿童的实际干预策略。于2005-11/2009-12在中国进行了一系列睡眠研究，包括全国横断面调查、前瞻性队列研究和学校睡眠干预。这项全国横断面调查在8个城市进行，随机抽取20778名年龄为9.0±1.61岁的儿童参与调查。这项为期五年的前瞻性队列研究包括612名年龄为6.8±0.31岁的儿童。在上海市6所小学进行横断面对照研究(基线：N = 525，年龄10.80±0.41；干预后随访：N = 553，年龄10.81±0.33)。一组家长和老师报告的问卷被用来收集关于孩子的睡眠行为、学校表现和社会人口学特征的信息。平均睡眠时间为9.35±0.77小时。白天嗜睡率为64.4%(有时为37.50%，经常为26.94%)。白天困倦与注意力受损、学习动机受损，尤其是学业成绩受损密切相关。相比之下，睡眠时间短只与学业成绩受损有关。分别推迟开学30分钟和60分钟后，睡眠时间分别相应增加15.6分钟和22.8分钟。此外，干预显著改善了睡眠时间和日间困倦。睡眠不足和白天嗜睡在中国学龄儿童中普遍存在，并与学习成绩，特别是学业成绩的下降呈正相关。推迟开学时间的有效性强调了最优的课时安排对儿童睡眠健康的好处。
Sufficient sleep during childhood is essential to ensure a transition into a healthy adulthood. However, chronic sleep loss continues to increase worldwide. In this context, it is imperative to make sleep a high-priority and take action to promote sleep health among children. The present series of studies aimed to shed light on sleep patterns, on the longitudinal association of sleep with school performance, and on practical intervention strategy for Chinese school-aged children. A serial sleep researches, including a national cross-sectional survey, a prospective cohort study, and a school-based sleep intervention, were conducted in China from November 2005 through December 2009. The national cross-sectional survey was conducted in 8 cities and a random sample of 20,778 children aged 9.0±1.61 years participated in the survey. The five-year prospective cohort study included 612 children aged 6.8±0.31 years. The comparative cross-sectional study (baseline: n = 525, aged 10.80±0.41; post-intervention follow-up: n = 553, aged 10.81±0.33) was undertaken in 6 primary schools in Shanghai. A battery of parent and teacher reported questionnaires were used to collect information on children’s sleep behaviors, school performance, and sociodemographic characteristics. The mean sleep duration was 9.35±0.77 hours. The prevalence of daytime sleepiness was 64.4% (sometimes: 37.50%; frequently: 26.94%). Daytime sleepiness was significantly associated with impaired attention, learning motivation, and particularly, academic achievement. By contrast, short sleep duration only related to impaired academic achievement. After delaying school start time 30 minutes and 60 minutes, respectively, sleep duration correspondingly increased by 15.6 minutes and 22.8 minutes, respectively. Moreover, intervention significantly improved the sleep duration and daytime sleepiness. Insufficient sleep and daytime sleepiness commonly existed and positively associated with the impairment of school performance, especially academic achievement, among Chinese school-aged children. The effectiveness of delaying school staring time emphasized the benefits of optimal school schedule regulation to children’s sleep health.
