The coronavirus disease 2019 pandemic led to various intensities of lockdowns, affecting lifestyles globally. This study investigates the impact of partial lockdown versus total lockdown on adult physical activity (PA) and sedentary behavior.
A cross-sectional online survey was conducted from April 2020 to October 2020, with 493 participants included in the analysis.
The analysis revealed no significant differences in total PA or total sitting time between partial lockdown and total lockdown scenarios. However, moderate physical activity (MPA) significantly decreased during total lockdowns, with more pronounced reductions among females than males. Notably, a positive correlation was found between household area and MPA, suggesting that larger living spaces may encourage more PA. A negative correlation was observed between sitting time and MPA during both types of lockdown.
Total lockdown conditions were associated with a significant decrease in MPA, highlighting sex disparities in PA responses. Living space size emerged as a crucial factor in maintaining PA levels during restricted conditions. This study emphasizes the need to consider environmental and demographic factors in public health strategies during prolonged periods of restricted movement.
2019年冠状病毒病大流行导致了不同强度的封锁，影响了全球各地的生活方式。本研究调查了部分封锁与全面封锁对成年人身体活动（PA）和久坐行为的影响。
于2020年4月至2020年10月进行了一项横断面在线调查，493名参与者纳入分析。
分析显示，部分封锁和全面封锁情况下，总身体活动量或总久坐时间无显著差异。然而，在全面封锁期间，中等强度身体活动（MPA）显著减少，女性的减少幅度比男性更明显。值得注意的是，家庭面积与中等强度身体活动之间存在正相关，表明更大的居住空间可能会鼓励更多的身体活动。在两种类型的封锁期间，久坐时间与中等强度身体活动之间均观察到负相关。
全面封锁条件与中等强度身体活动的显著减少有关，突出了身体活动反应中的性别差异。在行动受限的情况下，居住空间大小成为维持身体活动水平的关键因素。本研究强调在长期行动受限期间的公共卫生策略中，需要考虑环境和人口因素。
