Socioeconomic and clinical risk factors associated with moderate intensity physical activity before and during the COVID-19 pandemic.

Although moderate intensity physical activity (MIPA) improves general mental health, morbidity, and mortality, the COVID-19 pandemic may have adversely impacted individuals' ability to engage in MIPA. We examined the extent of socioeconomic factors, body mass index, anxiety/depression, and cancer diagnosis associated with MIPA before and during the COVID-19 pandemic. Multivariable logistic regression models were conducted on 4,551 U.S. adults aged 18-64 years using nationally representative samples from the 2019 and 2020 Health Information National Trends Survey datasets. The prevalence of MIPA before the pandemic was higher (77.07%) than during the pandemic (76.21%). Before the COVID-19 pandemic, lower odds of MIPA were observed for individuals with fair/poor health (OR = 0.24, 95% CI = 0.27, 0.63), obesity (OR = 0.51, 95% CI = 0.33, 0.79), anxiety/depression (OR = 0.60, 95% CI = 0.42, 0.85), or a cancer diagnosis (OR = 0.56, 95% CI = 0.32, 0.98). During the pandemic, lower odds were observed among those with obesity (OR = 0.44, 95% CI = 0.28, 0.70), anxiety/depression (OR = 0.61, 95% CI = 0.43, 0.86), less than high school education (OR = 0.33, 95% CI = 0.16, 0.70), or family income of $20,000 - $34,999 (OR = 0.42, 95% CI = 0.24, 0.74). There was a decline in MIPA during the pandemic, with certain subgroups, such as individuals of lower socioeconomic and physical and mental health status, less likely to engage in MIPA. This study highlights the need for concerted physical activity educational strategies aimed at improving access to and utilization of MIPA within subgroups to reduce MIPA disparities, particularly among disadvantaged groups during pandemics.
