2019冠状病毒病对社会生活的影响是巨大的，也是全球性的。然而，不同国家的不同病例数量和不同行动对人类行为产生了各种有趣但尚未探索的影响。在本研究中，我们比较了德国首次COVID-19封锁最严格时期之前和期间1711名4至17岁儿童的代表性样本的身体活动和娱乐屏幕时间。我们发现体育活动减少了，而娱乐屏幕时间增加了。然而，习惯性体育活动的大量增加导致德国儿童和青少年体育活动的总体增加。这种影响在大小上不同，但在方向上不同，对男孩和女孩来说是稳定的。我们从这个自然实验中得出结论，儿童和青少年的体育活动是高度情境驱动的，是相互的，并不会与娱乐屏幕时间在功能上相反。
The impact of COVID-19 on social life has been drastic and global. However, the different numbers of cases and different actions in different countries have been leading to various interesting yet unexplored effects on human behavior. In the present study, we compare the physical activity and recreational screen time of a representative sample of 1711 4- to 17-year-olds before and during the strictest time of the first COVID-19 lockdown in Germany. We found that sports activity declined whereas recreational screen time increased. However, a substantial increase in habitual physical activities leads to an overall increase in physical activity among children and adolescents in Germany. The effects differ in size but not in their direction between age groups and are stable for boys and girls. We conclude from this natural experiment that physical activity among children and adolescents is highly context-driven and mutual and does not act as a functional opposite to recreational screen time.
