The study was to examine county-level associations of physical activity with coronavirus disease 2019 (COVID-19) cases and deaths, per 100,000 county residents.
Data were collected from publicly available data sources for 3142 counties and equivalents, including the District of Columbia. Subjective health ratings, percentage uninsured, percentage unemployed, median household income, percentage female residents, percentage White residents, percentage of residents 65 years of age or older, and rural designation served as controls.
The two-level random intercept regression showed that physical activity rates at the county level were statistically and negatively associated with COVID-19 cases and deaths. Additional analyses showed that physical activity rates moderated the relationship between cases and deaths, such that the relationship was strongest when physical activity rates were low.
The results presented here offer empirical evidence of the benefits of county-level physical activity during a pandemic. Implications for public health and physical activity provision are discussed.
本研究旨在探讨每 10 万县居民中,身体活动与 2019 年冠状病毒病(COVID-19)病例和死亡之间的县级关联。
数据来自 3142 个县及同等地区(包括哥伦比亚特区)的公开数据来源。主观健康评分、未保险比例、失业比例、家庭中位数收入、女性居民比例、白人居民比例、65 岁及以上居民比例以及农村指定为对照。
两级随机截距回归显示,县级身体活动率与 COVID-19 病例和死亡呈统计学负相关。进一步分析表明,身体活动率调节了病例和死亡之间的关系,当身体活动率较低时,这种关系最强。
这里呈现的结果为大流行期间县级身体活动的益处提供了经验证据。讨论了对公共卫生和身体活动供应的影响。
