Abstract
This study examined the impact of COVID-19 on individuals' weight change and mental health by analyzing differences in risk perception, obesity, stress, depression, and intention to participate in leisure sports during the COVID-19 pandemic. Data were collected in the Republic of Korea between June and August 2022. This study included 374 individuals aged ≥ 20 years who regularly participated in leisure sports. A comparative analysis subdivided the participants into two groups based on weight changes during the pandemic: weight loss and maintenance (Group 1) and weight gain (Group 2). These formed the independent variable. The dependent variables were (a) infection risk perception, (b) obesity stress, (c) depression, and (d) intention to participate in sports. The results revealed statistically significant differences between the two groups in infection risk perception, obesity stress, and depression factors, but not in the intention to participate in sports. This study demonstrated the impact of COVID-19 on weight changes and mental health. These findings can guide future quarantine strategies to control new infectious diseases and policies to prevent obesity and stress.
