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），包括电视观看，玩电脑游戏和移动设备 使用在学龄前儿童中很常见。许多年幼的孩子超过了建议的<1小时/天 父母监督的TDM使用。这是因为TDM的过度使用与健康有关 问题，例如儿童超重和肥胖的风险更高。链接TDM使用的途径与 肥胖的风险尚未得到牢固确定，但睡眠是一个假设的调解人，保证了 调查。 TDM对儿童睡眠的任何影响也可能影响其他健康和发展成果 以前与儿童睡眠不佳有关。对幼儿中TDM使用的过去研究主要是退休的 在父母的报告中，儿童典型使用TDM，导致TDM使用过多和报告。这 因此，对过去研究的发现的有效性受到质疑。 Flash-TV是一项开发的新技术 由我们的团队被动，客观地衡量儿童对大型数字屏幕的观看，例如电视或视频 - 游戏机。在此提案中，我们建议利用Flash-TV以及测量的新方法 儿童使用移动设备，以稳健地评估儿童在多个平台上使用TDM（电视，移动设备） 设备和视频游戏控制台）在两个时间点，相距12个月的时间内10天。我们将结合小说 TDM使用评估具有强大的有效方法，用于测量儿童的睡眠（腕上伴有术语） 4岁儿童的多元化队列（n = 200）。孩子和父母将收集身高和体重。 父母将报告有假设会影响孩子TDM使用的家庭环境变量 （TDM育儿惯例，房屋的TDM清单，父母对孩子使用的结果期望以及 邻居障碍）和睡眠（睡眠育儿习惯，儿童睡眠卫生环境，父母 结果对儿童睡眠的期望）。这些新颖的方法是第一次被动地客观地进行 测量儿童在多天内在家庭环境中使用TDM的使用使我们能够通过IN和IN评估 在儿童TDM使用的儿童协会和基线时儿童睡眠之间，超过12个月。这项研究 设计还可以使我们能够更加牢固地评估儿童TDM使用与其体重之间的关联 状态超过12个月，睡眠是否介导了TDM和体重状态之间的关联。最后，我们会的 探索有关儿童TDM使用和睡眠的家庭和社交环境的关联 和纵向模型。为了促进该计划赠款中的协同作用和成本效益 项目2中将利用项目1建立的，以调查使用TDM对儿童的影响 发展结果。数字评估核心将为技术和处理支持 TDM和所有项目的睡眠评估以及生物统计学和数据库管理核心将确保 变量，数据库完整性和统计支持的协调。因此，该项目将有助于提供 TDM使用对儿童睡眠和体重状况的影响，以告知未来准则，这是第一个强大的数据。
