Examining the relationship between physical activity and mental health during the COVID-19 pandemic across five US States

The objectives of this paper are to investigate: 1) how the COVID-19 pandemic influenced both physical activity practices and mental health status, and 2) to assess the relationship between the two. Our mixed-methods study draws on 4,026 online survey responses collected between April - September 2020 across five states (Louisiana, Montana, North Carolina, Oregon and West Virginia). Logistic regression models were run for two outcome variables (physical activity and mental health status (measured using the Kessler Psychological Distress scale)). Researchers controlled for race/ethnicity, household income/size, gender, urbanicity, education, employment, use of government assistance and presence of chronic health conditions. Qualitative analysis was applied to open-ended survey responses to contextualize quantitative findings. Household income was significant in predicting difficulty maintaining pre-pandemic physical activity levels; pre-pandemic physical activity levels were associated with increased psychological distress levels during COVID-19; and race/ethnicity, income status and urbanicity were significantly associated with deteriorating mental health status and physical activity levels during COVID-19. Data suggests that a bi-directional, cyclical relationship between physical activity and mental health exists. Policy implications should include physical activity promotion as a protective factor against declining mental health.
