PHYSICAL ACTIVITY AND COVID-19 HOSPITALIZATION

Abstract
Objectives. Physical activity has been proposed as a protective factor for COVID-19
hospitalization. However, the mechanisms underlying this association are unclear. Here, we
examined the association between physical activity and COVID-19 hospitalization and
whether this relationship was explained by other risk factors for severe COVID-19.
Method. We used data from adults aged 50 years and older from the Survey of Health,
Ageing and Retirement in Europe. The outcome was self-reported hospitalization due to
COVID-19 measured before August 2020. The main exposure was usual physical activity,
self-reported..
