Pre-pandemic physical activity as a predictor of infection and mortality associated with COVID-19: Evidence from the National Health Insurance Service

Abstract

IntroductionDuring the coronavirus disease 2019 (COVID-19) pandemic, many populations have experienced reduced physical activity (PA) levels, weight gain, and increased anxiety and depression. However, according to a previous study, engaging in PA has a positive effect on damages caused by COVID-19. Therefore, this study aimed to investigate the association between PA and COVID-19 using the National Health Insurance Sharing Service Database in South Korea.MethodsLogistic regression analysis was used to analyze the association of PA with COVID-19 and mortality. The analysis was adjusted for body mass index, sex, age, insurance type, comorbidity, and region of residence at baseline. Disability and lifestyle (weight, smoking, and drinking status) were adjusted consecutively.ResultsThe results indicated that engaging in insufficient PA as per the WHO guidelines predicts a higher risk of COVID-19 when controlling for personal characteristics, comorbidity, lifestyle, disability, and mortality.DiscussionThis study revealed the need to engage in PA and manage weight to reduce the risk of infection and mortality associated with COVID-19. Because engaging in PA is an important component of weight management and can help restore physical and mental health after the COVID-19 pandemic, it should be emphasized as a pillar of recovery after COVID-19.

Differences in Physical Activity Levels by Sociodemographic and Health Risk Factors Among Persons With Disabilities in South Korea

“…Sex, age, health care coverage types, income quintiles, re-employment status, smoking status, drinking status, comorbidity, and region of residence, which are known to be related to physical activity, were adjusted as covariates. 18 Exercise status was considered by classifying them into under 20 years old, 20 to 39 years old, 40 to 64 years old, and 65 years old or older.…”
