Individual Characteristics Associated with Fears and Prevention Behaviors Related to Respiratory Infectious Disease among South Korean Adults Using Complex Sample Design.

Objectives: This study aimed to identify the relationships among individual characteristics, COVID-19-related fears, and infection-prevention behaviors using data from 228,932 adults (weighted to 43,583,798.71) aged 19 and older who participated in the 2021 Community Health Survey conducted by the Korea Disease Control and Prevention Agency.

Methods: The complex sample design analysis using SPSS 20.0 revealed the following.

Results: Women had statistically significantly higher COVID-19-related fears and a higher level of preventive behaviors compared to men. During the COVID-19 pandemic, the level of physical activity among men was higher than that of women. Compared to the period before COVID-19, the frequency of smoking and drinking decreased for both men and women, with the reduction being more pronounced in men than in women. The high-exercise group had a lower level of COVID-19-related fears. Self-perceived health status was inversely and significantly related to COVID-19-related fears. The low-exercise group had a lower score for self-perceived health status than the high-exercise group.

Conclusions: This study demonstrated that maintaining sufficient physical activity positively influences self-perceived health and reduces anxieties related to COVID-19 infection and fatalities. The results highlight the importance of physical activity and the need to identify strategies that effectively maintain regular exercise while adhering to infection-prevention measures during pandemics.
