OBJECTIVE
To evaluate if the variables child's sex, age, presence of siblings, parents working remotely, and external space affect the level of physical activity (PA) of Brazilian children during social distancing imposed by the COVID-19 pandemic.
METHODS
An online questionnaire was applied by the LimeSurvey software from March to April 2020. Children were divided into four age groups, and the questionnaire comprised questions on family and household characteristics, domestic and children's routines in the period of Brazilian social distancing. Based on the answers concerning children's activities, the following variable was created: percentage of physical activity (%PA) in one-day period. Analysis of variance and regression analysis were performed to investigate the effect of demographic and parental activities on %PA.
RESULTS
The %PA decreases with increasing age, but increases with the availability of external space at home. No significant or interaction effects were observed for other variables. Age and external space at home are predictors of %PA.
CONCLUSIONS
Household and personal characteristics of Brazilian children influence the level of physical activity performed by them during social distancing. Preventive measures can be adopted in the face of another similar period.
目的
评估儿童性别、年龄、是否有兄弟姐妹、父母远程工作以及外部空间等变量是否会影响巴西儿童在新冠疫情大流行期间实施社交距离措施时的身体活动（PA）水平。
方法
2020年3月至4月通过LimeSurvey软件进行在线问卷调查。儿童被分为四个年龄组，问卷包括有关家庭和家庭特征、巴西社交距离措施期间的家庭和儿童日常活动的问题。根据有关儿童活动的答案创建了以下变量：一天内身体活动百分比（%PA）。进行方差分析和回归分析以研究人口统计学和父母活动对%PA的影响。
结果
%PA随着年龄的增长而降低，但随着家中外部空间的可利用性而增加。未观察到其他变量有显著影响或交互作用。年龄和家中外部空间是%PA的预测因素。
结论
巴西儿童的家庭和个人特征会影响他们在社交距离措施期间的身体活动水平。面对另一个类似时期时可采取预防措施。
