The Obesity and the Metabolic Syndrome among Korean Adults: Based on National Representative Survey

Abstract

Background: The obesity and metabolic syndrome (MetS) are main health issues worldwide. This study was to investigate the association of obesity and MetS.Methods: A secondary analysis was conducted using data from Korea National Health and Nutrition Examination Survey for this study. The data from 10,488 Korean adults who were 30-64 years old were utilized and the pooled weights for the stratified complex sampling were implemented in the analysis. The participants were divided into five groups based on body mass index (BMI), and waist circumference, triglyceride, high density lipid, glucose, and blood pressures were used for the MetS.Results: The prevalence of MetS was 29.8% and it was higher in highly obese adults than people who has normal weights (odds ratio, 36.9; 95% confidence interval, 25.9-52.3) after adjusting age, gender, education, income, job, smoking, high risk drinking, and physical activity. There was gradients for the MetS and the components of MetS according to BMI.Conclusions: The obesity increased the risk of MetS and its components’ prevalence. The targeted intervention to control weight need to be developed and implemented. Further researches might be also needed to evaluate the effect of the weight loss on the decreased the risk of MetS.
