The severe acute respiratory syndrome coronavirus 2 disease (COVID-19) was first identified in December 2019 in Wuhan, China, and was declared a pandemic by the World Health Organization on 11 March, 2020. Since then, physical distancing measures such as confinement have been adopted by different governments to control human to human transmission. This study aimed to determine how confinement affects children's routines, more specifically their physical activity (PA) and sedentary time. An online survey was launched to assess how Portuguese children under 13 years of age adjusted their daily routines to confinement. Parents reported the time each child was engaged in different activities throughout the day, which was used to calculate overall sedentary time and overall physical activity time. Based on the data of 2159 children, our study showed that during confinement: (i) there was a decrease in children's physical activity time and an increase in screen time and family activities; (ii) boys engaged in more playful screen Time than girls ( < 0.05), and girls played more without PA than boys ( < 0.05); (iii) along the age groups, there was a trend for an increase of the overall sedentary time and an associated decrease of the overall physical activity time. In summary, PA of confined children showed low levels and a clear decreasing trend along childhood. Conjoint family and societal strategies to target specific age groups should be organized in the future.
严重急性呼吸综合征冠状病毒2疾病（COVID-19）于2019年12月在中国武汉首次被发现，并于2020年3月11日被世界卫生组织宣布为大流行病。从那时起，不同政府采取了诸如禁闭等物理距离措施来控制人际传播。本研究旨在确定禁闭如何影响儿童的日常活动，更具体地说是他们的身体活动（PA）和久坐时间。开展了一项在线调查，以评估13岁以下的葡萄牙儿童如何调整他们的日常活动以适应禁闭。家长报告了每个孩子全天参与不同活动的时间，这些时间用于计算总体久坐时间和总体身体活动时间。基于2159名儿童的数据，我们的研究表明，在禁闭期间：（i）儿童的身体活动时间减少，屏幕时间和家庭活动时间增加；（ii）男孩参与趣味性屏幕时间的比例高于女孩（<0.05），女孩在无身体活动情况下玩耍的时间比男孩多（<0.05）；（iii）在各年龄组中，总体久坐时间有增加趋势，而总体身体活动时间相应减少。总之，禁闭儿童的身体活动水平较低，且在整个童年期呈明显下降趋势。未来应制定针对特定年龄组的家庭和社会联合策略。
