We explored associations between neighbourhood environments and children and youths' moderate-to-vigorous physical activity (MVPA) during three different waves of the COVID-19 pandemic: spring 2020, fall 2020 and spring 2021, using three nationally representative cross-sectional surveys. In wave 2, higher dwelling density was associated with lower odds of a child achieving higher-level MVPA, however, the odds were higher in neighbourhoods with higher density that also had better access to parks. With regard to the social environment, ethnic concentration (wave 3) and greater deprivation (waves 1 and 3) were associated with lower odds of a child achieving higher-level MVPA. Results indicate that built and social environments were differently associated with MVPA levels depending on pandemic restrictions.
我们通过三次全国代表性的横断面调查，探索了在 COVID-19 大流行的三个不同时期（2020 年春季、2020 年秋季和 2021 年春季）邻里环境与儿童和青少年中等到剧烈身体活动（MVPA）之间的关联。在第 2 波中，更高的居住密度与儿童获得更高水平 MVPA 的几率较低有关，但在密度较高且更容易进入公园的社区中，这种几率更高。就社会环境而言，种族集中（第 3 波）和更大的贫困程度（第 1 波和第 3 波）与儿童获得更高水平 MVPA 的几率较低有关。结果表明，在大流行限制的情况下，建筑和社会环境与 MVPA 水平的关联不同。
