[Trends and Associated Factors of Moderate-to-vigorous Physical Activity among Adults Based on the Korea Community Health Survey Data].

Objectives: Physical activity is a critical public health strategy for preventing chronic diseases and enhancing mental well-being, contributing to an improved quality of life and increased healthy life expectancy. This study aimed to examine the trends and associated factors of moderate-to-vigorous physical activity (MVPA) among Korean adults and to suggest policy implications for improving health behaviors. Methods: We analyzed data from 229,242 adults aged 19 years or older who participated in the 2024 Korea Community Health Survey. MVPA status was set as the dependent variable, and sociodemographic, behavioral, and health-related factors were set as independent variables. Associations between variables were examined using the chi-squared test and multivariate logistic regression. Trends over time and regional distribution of MVPA rates were explored using descriptive statistics. All analyses were conducted using SAS 9.4, which incorporates a complex sample design. Results: In 2024, the MVPA rate was 26.6%, showing a gradual recovery after coronavirus disease 2019 but remaining below the pre-pandemic level. The MVPA rate was higher in rural areas than in large cities, and younger male were more likely to engage in MVPA. Adults in their 20s were 2.1 times more likely to engage in MVPA than those aged 70 years or older; male were 1.7 times more likely than female; and workers in agriculture, forestry, and fisheries were 2.2 times more likely than the unemployed. Higher MVPA rates were also observed among individuals without chronic diseases or depressive symptoms. Conclusions: The MVPA is influenced by both individual behaviors and social determinants such as sex, age, occupation, and health status. Addressing these disparities requires tailored strategies, supportive environments, and population-specific interventions.
