Technology and digital media (TDM), which includes TV viewing, playing computer games, and mobile device use, is common among preschool aged children. Many young children exceed the recommended <1 hour/day of parent supervised TDM use. This is concerning because excessive TDM use has been linked to health problems, such as higher risk of overweight and obesity among children. The pathways linking TDM use with risk of obesity have not been robustly established, but sleep is one hypothesized mediator that warrants investigation. Any impact TDM has on child sleep could also influence other health and developmental outcomes previously associated with poor sleep in children. Past studies of TDM use among young children primarily relied on parent report of children’s typical use of TDM, resulting in both over- and under-reporting of TDM use. The validity of findings from these past studies are therefore questioned. FLASH-TV is a new technology developed by our team to passively, objectively measure children’s viewing of large digital screens, such as TVs or video- game consoles. In this proposal we propose to leverage FLASH-TV along with new approaches for measuring children’s use of mobile devices, to robustly assess children’s use of TDM across multiple platforms (TV, mobile devices, and videogame consoles) over 10 days at two time-points, 12 months apart. We will combine the novel TDM use assessment with robust, valid approaches for measuring children’s sleep (wrist-worn acigraphy) in a diverse cohort of 4-year old children (n=200). Height and weight will be collected on the children and parents. Parents will report on home environmental variables that are hypothesized to influence the child’s TDM use (TDM parenting practices, TDM inventory of the home, parents’ outcome expectations for child’s TDM use, and neighborhood disorder) and sleep (sleep parenting practices, child’s sleep hygiene environment, parents’ outcome expectations for child’s sleep). For the first time, these novel approaches to passively and objectively measure children’s TDM use in their home environment over multiple days allows us to assess the with-in and between child association of children’s TDM use and children’s sleep at baseline and over 12 mo. This study design will also allow us to more robustly assess the association between children’s TDM use and their weight status over 12 mo, and whether sleep mediates the association between TDM and weight status. Lastly, we will explore the association of the home and social environments on children’s TDM use and sleep in cross-sectional and longitudinal models. To promote synergy and cost-effectiveness within this program grant, the cohort established in project 1 will be leveraged by project 2 to investigate the impact of TDM use on children’s developmental outcomes. A Digital Assessment Core will provide the technology and processing support for the TDM and sleep assessments of all projects and a Biostatistics and Database Management Core will ensure harmonization of variables, database integrity, and statistical support. This project will thereby help provide the first robust data for the influence of TDM use on children’s sleep and weight status to inform future guidelines.

技术和数字媒体(TDM)，包括看电视、玩电脑游戏和移动设备 使用，在学龄前儿童中很常见。许多幼儿每天超过推荐值1小时。 家长监督的TDM使用的比例。这是令人担忧的，因为过量使用TDM与健康有关 儿童超重和肥胖风险较高等问题。链接TDM使用的路径与 肥胖的风险还没有确凿的确定，但睡眠是一个假设的中介因素，这是有理由的 调查。TDM对儿童睡眠的任何影响也可能影响其他健康和发育结果 以前与儿童睡眠不佳有关。过去对幼儿使用TDM的研究主要依赖于 关于家长报告儿童使用TDM的典型情况，导致对TDM使用的多报和少报。这个 因此，过去这些研究结果的有效性受到了质疑。闪光灯电视是一项新兴的技术 由我们的团队被动、客观地衡量儿童观看电视或视频等大型数字屏幕的情况- 游戏机。在这项提案中，我们建议利用闪光灯电视以及新的测量方法 儿童使用移动设备，以强有力地评估儿童跨多个平台(电视、移动设备)使用TDM的情况 设备和视频游戏机)在两个时间点的10天内，相隔12个月。我们将结合这部小说 使用稳健、有效的方法进行TDM使用评估，以测量儿童的睡眠(戴手腕书法) 4岁儿童的不同队列(n=200)。将收集孩子和父母的身高和体重。 父母将报告假设会影响孩子TDM使用的家庭环境变量 (TDM育儿实践、家庭TDM清单、父母对孩子TDM使用的结果预期，以及 邻里关系障碍)和睡眠(睡眠父母的做法、孩子的睡眠卫生环境、父母的 对儿童睡眠的结果预期)。第一次，这些新的方法被动地和客观地 通过多天测量儿童在家庭环境中的TDM使用情况，我们可以评估 儿童使用TDM的儿童关联性与儿童在基线和12个月以上的睡眠之间的关系。本研究 设计还将使我们能够更有力地评估儿童使用TDM和他们的体重之间的联系 状态超过12个月，以及睡眠是否在TDM和体重状态之间的关联中起中介作用。最后，我们将 家庭和社会环境对儿童TDM使用和睡眠的影响 和纵向模型。为了在该计划赠款中促进协同作用和成本效益，该队列 项目1将利用项目2调查TDM使用对儿童的影响 发展成果。数字评估核心将提供技术和处理支持 所有项目的TDM和睡眠评估以及生物统计和数据库管理核心将确保 统一变量、数据库完整性和统计支持。因此，该项目将有助于提供 首先，使用TDM对儿童睡眠和体重状况的影响的可靠数据，为未来的指导方针提供参考。
