Do the Self-Reported Changes in Physical Activity After the Emergence of the COVID-19 Pandemic Associate With Major Depression According to Moderate to Vigorous Physical Activity Status?

Background: As the COVID-19 pandemic emerged, and social distancing increased, the physical activity (PA) of people decreased, which increased depression. The purpose of this study was to analyze the relationship between self-reported changes in PA with the COVID-19 pandemic and major depression according to moderate to vigorous physical activity (MVPA) status.

Methods: This study included 228,457 adults and used data from the Korea Community Health Survey 2020. Multiple logistic regression analysis was performed to evaluate the relationship between self-reported changes in PA and major depression stratified by MVPA status.

Results: The percentage of participants who reported decreases in PA was 39.5% in men and 44.7% in women compared with the pre-COVID-19 pandemic period. Those who reported decreases in PA after the onset of COVID-19 had major depression (men odds ratio = 1.28; 95% confidence interval, 1.15-1.43 and women odds ratio = 1.35; 95% confidence interval, 1.25-1.46). Women who were moderately or vigorously physically active had higher odds of major depression when they reported decreases in PA (odds ratio = 1.31; 95% confidence interval, 1.06-1.62).

Conclusions: People who reported decreases in PA were associated with major depression compared with the pre-COVID-19 pandemic period. Based on this, the government should encourage exercise to reduce major depression and provide guidelines for PA at home or outdoors.
