关于COVID-19大流行对儿童运动行为影响的大多数现有证据来自使用自我报告措施的横断面研究。本研究旨在确定来自美国德克萨斯州中部的学龄儿童的种族和社会经济多样性样本中客观评估的身体活动和久坐时间的变化轨迹及其相关因素，在COVID-19前（9月）2019年2月至2020年2月）和2020年10月至2021年3月期间，收集了参加德克萨斯州学校安全旅行环境评估（STREETS）队列研究的学龄儿童（8 - 11岁）的身体活动和久坐行为数据。使用GT3X-wBT Actigraph加速度计评估了中度至剧烈强度体力活动（MVPA）的每日时间和久坐时间。父母调查被用来评估社会生态因素。潜在类线性混合模型被用来识别MVPA和久坐时间的变化轨迹。Logistic回归模型被用来评估社会生态特征与体力活动和久坐时间变化轨迹组之间的关联。平均每日MVPA显著降低（− 9.4分钟，SD = 18.54），久坐行为增加（0.83小时，SD = 1.18）。确定了MVPA的两个轨迹组（"降低MPVA"和"维持高MPVA"），其中大多数（82.1%）在"降低MVPA"组。三个轨迹组被确定为久坐行为（“中度增加久坐，”急剧增加久坐，”和“减少久坐”），大多数儿童（78.5%）是在“中度增加”组。女孩处于"维持高MVPA"组的几率显著低于男孩（OR = 0.27，95%CI = 0.11，0.61）。生活在社会凝聚力较高的社区的儿童在"保持高MVPA"组中的几率显著较高（OR = 1.22，95%CI = 1.06，1.41），而生活在社会凝聚力较高的社区的儿童在"减少久坐"组中的几率较低（OR = 0.86，95%CI = 0.74，0.99）。在我们的研究中，在社会经济和种族多样化的美国样本中，在COVID-19期间，大多数学龄儿童的身体活动减少，久坐时间增加，特别是女孩。这些发现强调了抵消儿童运动行为因COVID-19而产生的短期负面变化的必要性。
Most available evidence on the effects of the COVID-19 pandemic on child movement behaviors is from cross-sectional studies using self-report measures. This study aimed to identify change trajectories and their associated factors for objectively-assessed physical activity and sedentary time among an ethnically and socioeconomically diverse sample of school-age children from Central Texas, U.S.A., during COVID-19. Pre- (Sept. 2019 – Feb. 2020) and during- (Oct. 2020 – March 2021) COVID-19 physical activity and sedentary behavior data were collected for school-age children (8–11 years) enrolled in the Safe Travel Environment Evaluation in Texas Schools (STREETS) cohort study. Daily time spent in moderate- to vigorous-intensity physical activity (MVPA) and sedentary time were assessed using GT3X-wBT Actigraph accelerometers. Parent surveys were used to assess socio-ecological factors. Latent class linear mixed models were used to identify change trajectories of MVPA and sedentary time. Logistic regression models were used to assess the association between socio-ecological characteristics with physical activity and sedentary time change trajectory groups. There was a significant decrease in mean daily MVPA (− 9.4 mins, SD = 18.54) and an increase in sedentary behavior (0.83 hrs, SD = 1.18). Two trajectory groups were identified for MVPA (‘decrease MPVA’ and ‘maintain high MVPA’), with the majority (82.1%) being in the ‘decrease MVPA’ group. Three trajectory groups were identified for sedentary behavior (‘moderate increase sedentary, ‘steep increase sedentary,’ and ‘decrease sedentary’), with most children (78.5%) being in the ‘moderate increase’ group. Girls had significantly lower odds of being in the ‘maintain high MVPA’ group than boys (OR = 0.27, 95% CI = 0.11, 0.61). Children living in neighborhoods with higher perceived social cohesion had significantly higher odds of being in the ‘maintain high MVPA’ group (OR = 1.22, 95% CI = 1.06, 1.41), while those in neighborhoods with higher social cohesion had lower odds of being in the ‘decrease sedentary’ group (OR = 0.86, 95% CI = 0.74, 0.99). Declines in physical activity and increases in sedentary time among most school-age children during COVID-19 in a socioeconomically and ethnically diverse U.S. sample, were observed in our study, especially among girls. These findings highlight the need to counteract the short-term negative changes in movement behaviors in response to COVID-19 among children.
