Greater consumption of and access to screen media are known correlates of unhealthy sleep behavior in preschoolers. What remains unknown, however, is the role a child's media use plays in this association. Parents and guardians of U.S. preschoolers (N = 278, average child age 56 months) provided information about their child's nightly duration of sleep, daily duration of nap, quantity of screen media use, sneaky media use, and the presence of a screen media device in the bedroom. We assessed four media: television, DVD/VCRs, video games, and computer/Internet. Based on rationales of sleep displacement, the forbidden fruit hypothesis, and social cognitive theory, we predicted that increased consumption of and access to media, along with sneaky media use, would predict a shorter duration of nightly sleep and longer duration of daily nap across the four screen media. In correlational analyses, a clear pattern emerged with quantity of media use, screen media in the bedroom, and sneaky media use associated with shorter nightly duration of sleep and longer duration of daily nap. In regression analyses, only weekday evening television viewing and sneaky media use predicted shorter nightly sleep duration; weekend morning and evening DVD use predicted longer naps.
屏幕媒体的更多消费和获取是学龄前儿童不健康睡眠行为的已知相关因素。然而，目前尚不清楚孩子的媒体使用在这种关联中扮演什么角色。美国学龄前儿童（N=278，平均儿童年龄为 56 个月）的父母和监护人提供了有关其孩子每晚睡眠时间、每日午睡时间、屏幕媒体使用量、偷偷摸摸使用媒体以及卧室中是否有屏幕媒体设备的信息。我们评估了四种媒体：电视、DVD/VCR、视频游戏和计算机/互联网。基于睡眠移位的原理、禁果假说和社会认知理论，我们预测，随着媒体消费和获取的增加，以及偷偷摸摸地使用媒体，会预测在这四种屏幕媒体中，每晚睡眠时间更短，每天午睡时间更长。在相关分析中，随着媒体使用量、卧室中的屏幕媒体和偷偷摸摸使用媒体的增加，出现了清晰的模式，与每晚睡眠时间缩短和每天午睡时间延长相关。在回归分析中，只有工作日晚上看电视和偷偷摸摸地使用媒体会预测每晚睡眠时间缩短；周末早晚使用 DVD 则预测午睡时间延长。
