PROJECT SUMMARY/ABSTRACT Children’s screen media use has increased dramatically in recent years. Greater screen use, especially during the evening hours, is routinely, though not unequivocally, associated with disruption of sleep including shorter sleep duration, difficulty falling asleep, and reduced overall sleep quality. Based in a wealth of research showing poor sleep health in childhood to robustly forecast a wide range of adverse outcomes (e.g., obesity, psychiatric disorders, poor cognitive and academic performance, emotion dysregulation, increased risk-taking behaviors, suicidality), current guidelines provided by virtually every major pediatric health organization/association recommend that children avoid use of electronic screens in the hour before bed. While perhaps intuitive, empirical evidence to support this guideline is largely cross-sectional. That is, causal effects of evening screen use on children’s sleep and circadian timing have not been sufficiently demonstrated nor have the mechanism(s) through which sleep disruption may occur been clarified. Experimental studies are therefore necessary to provide professionals and parents with evidence-based guidance and inform developmental research. The goal of the current study is to systematically test the impact of light exposure from screens as well as arousing media content on N=200 school-aged children’s (8 to 11 years) sleep regulation and circadian timing, in addition to next-day emotion regulation and executive functioning. Our novel ability to objectively assess and account for children’s daytime tablet use history will allow us to accurately isolate the effects of evening screen use on children’s sleep. Using a 4-group randomized, controlled design including assessment of typical sleep and media use followed by a 3-day experimental protocol, we plan to: 1) systematically test the effects of evening screen media use in the natural home environment on children’s sleep duration, sleep latency, and subjective sleep quality; 2) translate experimental research methods from the laboratory to the home environment to examine the impact of bright light emitted from screens and exposure to arousing media content on children’s sleep, circadian physiology, and physiological arousal; 3) examine the role of evening screen use on children’s next day executive functioning and emotion regulation. The proposed research addresses several critical gaps in scientific knowledge regarding the impact of evening screen media use on children’s sleep health, including elucidating the specific mechanism(s) through which potential negative impacts may occur. Results may directly inform national guidelines and policies regarding evening screen media use in all children.

项目概要/摘要 近年来，儿童屏幕媒体的使用急剧增加，尤其是在儿童时期。 晚上的时间是例行公事，尽管并非明确，但与睡眠中断有关，包括较短的睡眠时间 大量研究表明，睡眠持续时间、入睡困难和整体睡眠质量下降。 儿童睡眠健康状况不佳可以有力地预测各种不良后果（例如肥胖、精神疾病） 疾病、认知和学习成绩不佳、情绪失调、冒险行为增加、 自杀倾向），几乎每个主要儿科健康组织/协会都提供了最新指南 建议孩子在睡前一小时避免使用电子屏幕，虽然可能很直观，但 支持这一指导方针的经验证据主要是横截面的，即夜间屏幕的因果效应。 对儿童睡眠和昼夜节律的使用尚未得到充分证明，也没有相关机制 因此，有必要进行实验研究来阐明可能发生的睡眠中断。 专业人士和家长提供基于证据的指导并为发展研究提供信息。 目前的研究是系统地测试屏幕曝光的影响以及激发媒体内容 对 N=200 名学龄儿童（8 至 11 岁）的睡眠调节和昼夜节律时间以及第二天进行研究 情绪调节和执行功能。我们客观评估和解释儿童的新能力。 白天使用平板电脑的历史记录将使我们能够准确地隔离晚上使用屏幕对儿童睡眠的影响。 采用 4 组随机对照设计，包括评估典型睡眠和媒体使用情况 通过为期 3 天的实验方案，我们计划：1）系统地测试晚间屏幕媒体使用的效果 自然家庭环境对儿童睡眠持续时间、睡眠潜伏期和主观睡眠质量的影响2) 将实验研究方法从实验室转移到家庭环境中，以检验其影响 屏幕发出的强光以及接触引起儿童睡眠、昼夜节律的媒体内容 生理学和生理唤醒；3）研究夜间屏幕使用对儿童第二天执行力的作用 拟议的研究解决了科学上的几个关键差距。 关于夜间屏幕媒体使用对儿童睡眠健康影响的知识，包括阐明 结果可能直接告知可能产生潜在负面影响的具体机制。 关于所有儿童夜间屏幕媒体使用的国家准则和政策。
