Regional factors associated with the prevalence of metabolic syndrome: Focusing on the role of healthcare providers.

Abstract

Metabolic syndrome (MetS) is associated with an increased risk of cardiovascular disease, which is gradually becoming more prevalent due to changes in dietary habits and lifestyle. The aim of this study was to evaluate the association between regional factors and the prevalence of MetS, with a particular focus on access to healthcare providers. Observational study. We used data from the annual Korea National Health and Nutrition Examination Survey (2013-2017), which included 24,695 eligible participants. Regional factors that were related to access to care and could affect the prevalence of MetS were evaluated. A generalised estimating equation model was utilised to identify variables associated with the prevalence of MetS. In this study, the prevalence of MetS was 25.9% (n=7,100). Results of the generalised estimating equation model indicated that a higher density of physicians was significantly associated with a lower prevalence of MetS (odds ratio: 0.864, 95% confidence interval: 0.758-0.984). The density of community health nurses was not significantly associated with the prevalence of MetS; however, the subgroup analysis revealed that higher densities of physicians and community health nurses were significantly associated with a low prevalence of MetS in regions with a high proportion of community health centres. Regional factors related to access to care were associated with the prevalence of MetS. Higher physician density and community health centre utilisation rates were associated with a decreased prevalence of MetS. Regional differences in access to care should be addressed to reduce the health gap between regions and prevent the development of MetS.
