该研究调查了2019冠状病毒病大流行期间青少年的体育活动。中度至剧烈体力活动的中位数为每周2小时。在大流行期间，8.9%的人符合体育活动指南，而在大流行之前，这一比例为16.1%。心理健康状况不佳、担忧和压力与身体活动减少有关。较高的应对和社会支持与较高的体力活动。这项研究旨在评估青少年在COVID-19大流行期间的中等至剧烈强度体力活动（MVPA）的社会人口学特征，并确定10-14岁青少年的不同国家样本中与MVPA相关的心理健康和弹性因素。数据于2020年5月大流行期间从青少年大脑认知发展研究（ABCD，N = 5，153）中收集，该研究是美国的一项全国性前瞻性队列研究。MVPA被量化为报告的持续时间和频率（每周小时数）的乘积，并进一步总结为符合2018年美国人身体活动指南的年龄比例。使用大流行之前收集的MVPA数据得出了类似的估计数。在大流行期间收集了心理健康和复原力指标。回归模型研究了大流行期间心理健康或弹性措施与MVPA之间的关联。中位MVPA为每周2小时（IQR 0，6）。总体而言，符合MVPA指南的队列百分比从16.1%（大流行前）降至8.9%（大流行期间）。种族/少数民族青少年和来自较低社会经济背景的青少年在大流行期间达到MVPA指南的可能性明显较低。流行性心理健康、与COVID相关的担忧和压力与较低的MVPA相关，而在大流行期间，更多的社会支持和应对行为与较高的MVPA相关。在这个全国性的大型青少年样本中，在COVID-19大流行期间，符合MVPA指南的青少年比例较低，种族/民族和社会经济地位存在显著差异。促进社会支持和应对行为的干预措施可能会改善大流行期间青少年的MVPA水平。
The study examined adolescents’ physical activity during the COVID-19 pandemic. Median moderate-to-vigorous physical activity was 2 h per week. 8.9% met physical activity guidelines during the pandemic compared to 16.1% before. Poor mental health, worry, and stress were associated with lower physical activity. Higher coping and social support were associated with higher physical activity. This study aimed to evaluate adolescents’ moderate-to-vigorous intensity physical activity (MVPA) during the COVID-19 pandemic with regards to sociodemographic characteristics and determine mental health and resiliency factors associated with MVPA among a diverse national sample of adolescents ages 10–14 years. Data were collected during the pandemic in May 2020 from the Adolescent Brain Cognitive Development Study (ABCD, N = 5,153), a national prospective cohort study in the U.S. MVPA was quantified as the product of reported duration and frequency (hours per week), which was further summarized as the proportion meeting age-appropriate 2018 Physical Activity Guidelines for Americans. A similar estimate was generated using MVPA data collected prior to the pandemic. Mental health and resiliency measures were collected during the pandemic. Regression models examined associations between mental health or resiliency measures and MVPA during the pandemic. Median MVPA was 2 h per week (IQR 0, 6). Overall, the percentage of the cohort meeting MVPA guidelines decreased from 16.1% (pre-pandemic) to 8.9% (during the pandemic). Racial/ethnic minority adolescents and adolescents from lower socioeconomic backgrounds were significantly less likely to meet MVPA guidelines during the pandemic. Poorer mental health, COVID-related worry, and stress were associated with lower MVPA, while more social support and coping behaviors were associated with higher MVPA during the pandemic. In this large, national sample of adolescents, the proportion of those meeting MVPA Guidelines was lower during the COVID-19 pandemic, with significant disparities by race/ethnicity and socioeconomic status. Interventions to promote social support and coping behaviors may improve MVPA levels among adolescents during the pandemic.
