The levels of adequacy of movement behaviors after returning to in-person school activities following the COVID-19 pandemic are not yet well understood. This study aimed to assess the adherence of Brazilian minors to the recommendations of the 24-Hour Movement Guidelines (moderate to vigorous physical activity, recreational screen time, and sleep duration), as well as overall adherence to these guidelines, after the relaxation of COVID-19 social isolation measures and the resumption of in-person schooling. A cross-sectional study was conducted with parents or guardians (39 ± 7.8) of minors aged up to 18 years of age (3.8 ± 2.5). A total of 172 individuals responded to the questionnaire. Data were compared with those obtained in the Survey of the Adequacy of Brazilian Children and Adolescents to the 24-Hour Movement Guidelines before and during the COVID-19 Pandemic. There was an 18.6 percentage decrease (-value < 0.001) in overall adherence to the 24-Hour Movement Guidelines when comparing the periods before the COVID-19 pandemic (March 2020) and after the return to in-person schooling (March 2021). The largest percentage drop in adherence between these periods was observed for moderate to vigorous physical activity (27.4%; -value < 0.001) and the lowest for sleep (10.5%; -value < 0.001). Adherence to the 24-Hour Movement Guidelines did not return to pre-pandemic levels with the resumption of in-person school activities.
在 COVID-19 大流行后恢复面对面学校活动后，运动行为的充分性水平尚不清楚。本研究旨在评估巴西未成年人在放松 COVID-19 社会隔离措施并恢复面对面学校教育后，对 24 小时运动指南（中等到剧烈的体力活动、娱乐屏幕时间和睡眠时间）建议的遵守情况，以及对这些指南的整体遵守情况。这是一项横断面研究，涉及年龄在 18 岁以下的未成年人的父母或监护人（39 ± 7.8）。共有 172 人回答了问卷。将数据与 COVID-19 大流行前后进行的巴西儿童和青少年对 24 小时运动指南充足性调查中获得的数据进行了比较。与 COVID-19 大流行前（2020 年 3 月）相比，在恢复面对面学校教育后（2021 年 3 月），整体遵守 24 小时运动指南的比例下降了 18.6%（-值<0.001）。在这些时期之间，中等到剧烈的体力活动的遵守率下降幅度最大（27.4%；-值<0.001），睡眠的下降幅度最小（10.5%；-值<0.001）。随着面对面学校活动的恢复，对 24 小时运动指南的遵守并没有恢复到大流行前的水平。
