项目摘要

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)，包括观看电视、玩电脑游戏和移动设备使用，在学龄前儿童中很常见，许多幼儿超过建议的每天 1 小时。家长监督 TDM 使用的情况令人担忧，因为过度使用 TDM 与健康有关。 TDM 的使用与儿童超重和肥胖风险较高等问题相关。肥胖的风险尚未得到充分证实，但睡眠是一种高级调节因素，值得研究调查显示，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。过去对幼儿使用 TDM 的研究主要依赖于儿童睡眠不良。家长报告儿童 TDM 的典型使用情况，导致 TDM 使用情况的多报和少报。因此，过去这些研究结果的有效性受到质疑。由我们的团队被动、客观地测量儿童观看大型数字屏幕（例如电视或视频）的情况- 在本提案中，我们建议利用 FLASH-TV 以及新的测量方法。儿童使用移动设备的情况，以稳健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 10 天的两个时间点（相隔 12 个月）我们将合并小说。 TDM 使用评估采用稳健、有效的方法来测量儿童睡眠（腕戴式记录仪）将收集 4 岁儿童的不同群体（n = 200）的身高和体重。家长将报告家庭环境变量，这些变量会影响孩子的 TDM 使用（TDM 育儿实践、家庭 TDM 库存、父母对孩子使用 TDM 的结果期望，以及邻里关系混乱）和睡眠（睡眠养育方式、孩子的睡眠卫生环境、父母的睡眠习惯）这些新颖的方法首次被动而客观地评估了儿童睡眠的结果期望。测量儿童在家庭环境中多天的 TDM 使用情况使我们能够评估儿童的内部和外部情况这项研究探讨了儿童 TDM 使用与儿童基线和 12 个月以上睡眠之间的关系。设计还将使我们能够更稳健地评估儿童 TDM 使用与其体重之间的关联 12 个月内的健康状况，以及睡眠是否介导 TDM 与体重状况之间的关联。横断面探索家庭和社会环境与儿童 TDM 使用和睡眠的关系和纵向模型。为了促进该计划拨款中的协同作用和成本效益，该队列项目 2 将利用项目 1 中建立的模型来调查 TDM 使用对儿童的影响数字评估核心将为开发成果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该项目将有助于提供变量的协调、数据库的完整性和统计支持。关于 TDM 使用对儿童睡眠和体重状况影响的第一个可靠数据，可为未来的指南提供信息。
