Objective

To determine sociodemographic correlates of contemporary screen time use among a diverse population-based sample of 9- and 10-year-old children.

Study design

In 2021, we analyzed cross-sectional baseline (2016-2018) data from the Adolescent Brain Cognitive Development study (n = 10 755). Multiple linear regression analyses were conducted to estimate associations between sociodemographic factors (sex, race/ethnicity, country of birth, household income, parental education) and 6 contemporary forms of screen time (television, videos [eg, YouTube], video games, social networking, texting, and video chat).

Results

On average, children reported 3.99 hours of screen time per day across 6 modalities, with the most time spent watching/streaming television shows/movies (1.31 hours), playing video games (1.06 hours), and watching/streaming videos (1.05 hours). On average, Black children reported 1.58 more hours of screen time per day and Asian children reported 0.35 less hours of screen time per day compared with White children (mean 3.46 hours per day), and these trends persisted across most modalities. Boys reported higher overall screen time (0.75 hours more) than girls, which was primarily attributed to video games and videos. Girls reported more time texting, social networking, and video chatting than boys. Higher income was associated with lower screen time usage across all modalities except video chat. However, in high-income households, Latinx children reported 0.65 more hours of screen time per day than White children.

Conclusions

Given the sociodemographic differences in child screen use, guideline implementation strategies can focus on key populations, encourage targeted counseling by pediatricians, and adapt Family Media Use Plans for diverse backgrounds.

9 岁和 10 岁儿童当代屏幕时间使用的社会人口学相关性

客观的

在 9 岁和 10 岁儿童的不同人群样本中确定当代屏幕时间使用的社会人口统计学相关性。

学习规划

2021 年，我们分析了青少年大脑认知发展研究（n = 10 755）的横截面基线（2016-2018 年）数据。进行多元线性回归分析以估计社会人口因素（性别、种族/民族、出生国家、家庭收入、父母教育）与 6 种当代形式的放映时间（电视、视频 [例如 YouTube]、视频游戏、社交网络、短信和视频聊天）。

结果

平均而言，儿童每天在 6 种方式中的屏幕时间为 3.99 小时，其中大部分时间用于观看/播放电视节目/电影（1.31 小时）、玩电子游戏（1.06 小时）和观看/播放视频（1.05 小时） . 平均而言，与白人儿童（平均每天 3.46 小时）相比，黑人儿童每天看屏幕的时间多 1.58 小时，亚裔儿童每天看屏幕的时间少 0.35 小时，而且这些趋势在大多数模式中都存在。男孩报告的总屏幕时间比女孩长（多 0.75 小时），这主要归因于视频游戏和视频。女孩发短信、社交网络和视频聊天的时间比男孩多。更高的收入与视频聊天以外的所有方式的屏幕使用时间减少相关。然而，在高收入家庭中，

结论

鉴于儿童屏幕使用的社会人口差异，指南实施策略可以关注关键人群，鼓励儿科医生进行有针对性的咨询，并针对不同背景调整家庭媒体使用计划。
