To determine the associations between Adverse Childhood Experiences (ACEs), adolescent screen time, and physical activity during the early COVID-19 pandemic.
Data (2016-2020) from the Adolescent Brain Cognitive Development (ABCD) study were analyzed. Linear regression analyses estimated associations between ACE score and screen time and physical activity in May 2020, adjusting for potential confounders.
Of the 6749 adolescent respondents primarily aged 12-13, 81.6% reported a history of one ACE or more. In adjusted models, a higher ACE score was significantly associated with greater hours per day of screen time, with youth with ≥4 ACEs associated with 2.3 more hours of screen time per day compared to youth with 0 ACEs. In addition, the adjusted models found that a higher ACE score was associated with lower physical activity; youth with ≥4 ACEs averaged 0.8 fewer hours per week of physical activity and 0.5 fewer days per week of 60 minutes of physical activity compared to youth with 0 ACEs. Gender and race were also significantly associated with changes in screen time and physical activity.
ACEs are associated with higher adolescent sedentary behaviors, particularly greater screen time, during the early COVID-19 pandemic (May 2020). Clinicians caring for youth exposed to trauma in the postpandemic environment should explore screen time and physical activity behaviors.
确定不良童年经历（ACEs）、青少年屏幕时间和新冠疫情早期期间身体活动之间的关联。
分析了青少年大脑认知发展（ABCD）研究中的数据（2016-2020 年）。线性回归分析估计了 2020 年 5 月 ACE 评分与屏幕时间和身体活动之间的关联，调整了潜在的混杂因素。
在 6749 名主要年龄在 12-13 岁的青少年应答者中，81.6%报告有一个或多个 ACE 经历。在调整后的模型中，较高的 ACE 评分与每天更多的屏幕时间显著相关，与没有 ACE 的青少年相比，具有≥4 个 ACE 的青少年每天的屏幕时间多 2.3 小时。此外，调整后的模型发现，较高的 ACE 评分与较低的身体活动相关；与没有 ACE 的青少年相比，具有≥4 个 ACE 的青少年每周的身体活动时间平均少 0.8 小时，每周进行 60 分钟身体活动的天数少 0.5 天。性别和种族也与屏幕时间和身体活动的变化显著相关。
在新冠疫情早期（2020 年 5 月），ACEs 与青少年久坐行为（尤其是更多的屏幕时间）相关。在后疫情环境中照顾经历过创伤的青少年的临床医生应探讨屏幕时间和身体活动行为。
