Objectives: The purpose of this study was to examine the factors affecting regional disparities in the prevalence of adult obesity.
Methods: This study is an ecological study in which the unit of analysis were 229 local authorities (si = 78, gun = 82, and gu = 68). The data were obtained from database (ver 1.1) of community health outcomes and health determinants (2015-2017) and Community Health Survey data (2018-2019). Multiple regression analysis was used to identify factors related to the prevalence of obesity in 4 groups (all regions, si, gun, and gu).
Results: The prevalence of regional obesity varied 23.5% to 45.15% with a mean of 34.13%. Obesity prevalence was highest in ¡®gun¡¯, and lowest in ¡®gu¡¯ area. In the overall model, sociodemographic characteristics including sex ratio (¥â= 0.26), household income over 3 million won (¥â= -0.23), and the unemployment (¥â= -0.18)), high-risk drinking (¥â= 0.18), and satisfaction with public transportation (¥â= -0.24) were associated with the prevalence of regional obesity. Other than those things, in ¡®si¡¯ area, population density, walking practice, in ¡®gun¡¯ area, participation in social activity were associated with the prevalence of regional obesity.
Conclusions: To reduce obesity prevalence and it¡¯s regional disparities, it is important to make intervention and prevention efforts taking into account the socioeconomic and physical environmental characteristics of the region as well as health behaviors.
