目的：为了研究适度的睡眠延长和限制对儿童在校行为的影响，我们进行了一项随机平行组研究，以确定实验性睡眠延长（相对于工作日基线习惯性睡眠持续时间增加1小时）和实验性睡眠限制（相对于工作日基线习惯性睡眠持续时间消除1小时）对儿童在校行为的影响。主要结果测量是Conners全球指数量表的分数，由对参与者睡眠状况不知情的教师确定。34名年龄在7到11岁之间的正常发育儿童参与了这项研究，他们没有报告睡眠问题，也没有行为、医疗或学术问题。我们的主要发现是：（1）睡眠持续时间累计延长27.36分钟与Conners全球指数衍生的情绪不稳定和不安的可检测改善相关;在学校的孩子的冲动行为得分和报告的白天嗜睡的显着减少;和（2）睡眠的54.04分钟的累积限制与这些措施的可检测的恶化相关。适度延长睡眠时间与警觉性和情绪调节的显着改善有关，而适度的睡眠限制则有相反的效果。儿科2012;130：e1155-e1161
OBJECTIVE: To examine the impact of moderate sleep extension and restriction on child behavior in school.METHODS: We conducted a randomized parallel group study to determine the impact of an experimental sleep extension (addition of 1 hour of sleep relative to baseline habitual sleep duration on weekdays) and experimental sleep restriction (elimination of 1 hour of sleep relative to baseline habitual sleep duration on weekdays) on child behavior in school. The primary outcome measures were scores on the Conners' Global Index Scale, as determined by teachers blinded to sleep status of the participants. A sample of 34 typically developing children aged 7 to 11 years with no reported sleep problems and no behavioral, medical, or academic issues participated in the study.RESULTS: Our main findings were that (1) a cumulative extension of sleep duration of 27.36 minutes was associated with detectable improvement in Conners' Global Index-derived emotional lability and restless-impulsive behavior scores of children in school and a significant reduction in reported daytime sleepiness; and (2) a cumulative restriction of sleep of 54.04 minutes was associated with detectable deterioration on such measures.CONCLUSIONS: A modest extension in sleep duration was associated with significant improvement in alertness and emotional regulation, whereas a modest sleep restriction had opposite effects.
