Abstract：
We identified the association of changes in moderate-to-vigorous physical activity (MVPA) with SARS-CoV-2 infection. From 6,396,500 patients, we performed a nested case-control study who participated in both biennial check-ups. Adjusted odds ratios (aOR) and 95% confidence intervals (CI) were calculated using multivariable logistic regression. From physically inactive patients at period I, the odds increased when engaged in 1-2, 3-4, or ≥5 times of MVPA/week at period II. This study found that MVPA was directly associated with SARS-CoV-2 infection.
摘要：
我们确定了中度至剧烈体力活动（MVPA）变化与SARS-CoV-2感染的关系。来自6,396,500名患者，我们进行了一项巢式病例对照研究,该研究参与了两项两年一次的检查.使用多变量逻辑回归计算调整比值比（aOR）和95％置信区间（CI）。从第一阶段身体不活跃的患者，在II期进行1-2、3-4或≥5次MVPA/周的活动时,几率增加.本研究发现MVPA与SARS-CoV-2感染直接相关。
