Poster Topical Area: Nutritional Epidemiology

Objectives:This study was performed to investigate nutrient intake and the prevalence of metabolic syndrome (MetS) in middle-aged Koreans according to residential areas.
Methods: A total of 161,326 middle-aged residents from urban (n=142,137) and rural (n=19,189) areas were selected from the Health Examinee cohort (HEXA) and Cardiovascular Disease Association Study cohort (CAVAS), two subprojects of the Korean Genome and Epidemiology Study (KoGES). Data were collected using self-administered questionnaires, and analyzed for nutrient intake and MetS prevalence. The MetS was defined by the modified National Cholesterol Education Program (NCEP) Adults Treatment Panel III criteria for Asians.
Results: Rural residents had a significantly lower energy intake compared to urban population (P < 0.001). After adjustment for potential confounding variables, intakes of carbohydrate and sodium were significantly higher in the rural population than urban population (P < 0.001). However, the consumption of protein, fat, and micronutrients except sodium, were significantly lower in rural residents than those of urban dwellers. Subjects in the rural areas showed a significantly higher prevalence of MetS (39.8% in rural and 22.5% in urban, P < 0.001) and a higher odds ratio of MetS risk [OR (95% CI ) = 2.26 (2.19‒2.33)] than urban participants.
Conclusions: Our results suggested that rural dweller’ higher consumption of carbohydrates and sodium may partially contribute to a higher risk of MetS in this population.
