Teen Weekend Sleep: Circadian Timing, Performance, Mood

描述（由申请人提供）：本申请的主要目的是在周末恢复睡眠行为的背景下检查高中生的昼夜节律时间和日间功能。上学的夜晚和周末的夜晚睡眠时间之间的巨大差异与不良的日间功能（例如，学习成绩差，情绪低落）。本研究的第一个目的是检查可能导致这种关联的昼夜节律因素。在周末修改睡眠模式以保持稳定的昼夜节律时间可以减弱日间功能减退。因此，这项研究的第二个目的是测试一种替代的周末睡眠时间表，以稳定昼夜节律系统。拟议的研究使用受试者内平衡设计，两种条件的差异仅在于以下强制周末睡眠/觉醒时间表：通常观察到的晚起时间表和具有稳定夜间睡眠和午睡的替代时间表。昼夜节律阶段，主观嗜睡，认知吞吐量，情绪和警惕性评估之前和之后的每个周末的条件。这项研究可能会进一步了解日间功能不良的危险因素，并将评估睡眠行为，可能会减轻这些递减在青少年。

DESCRIPTION (provided by applicant): The broad aim of this application is to examine circadian timing and daytime function in high school students in the context of weekend recovery sleep behavior. Large disparity between school night and weekend night sleep timing is associated with poor daytime function (e.g., poor academic grades and depressed mood). The first aim of this study is to examine circadian factors that may contribute to this association. Modifying sleep patterns on the weekend to maintain stable circadian timing may attenuate daytime function decrements. Thus, the second aim of this study is to test an alternative weekend sleep schedule that stabilizes the circadian system. The proposed study uses a within subjects counterbalanced design with two conditions that differ only by the following enforced weekend sleep/wake schedules: the commonly observed, late rise time schedule and an alternative schedule with stable nocturnal sleep and an afternoon nap. Circadian phase, subjective sleepiness, cognitive throughput, mood, and vigilance assessments precede and follow each weekend condition. This study may further the understanding of risk factors for poor daytime function and will evaluate sleep behaviors that may attenuate these decrements in teens.
