Objectives: The purpose of this study was to assess the prevalence of hypertriglyceridemic waist (HTGW) and its association with demographic and metabolic factors in Korean population. Methods: Data were obtained from the 2001 Korean National Health and Nutrition Examination Survey (KNHNE), which was a cross-sectional national health survey. Results: The total study population amounted to 29,506 individuals, aged 15 years and older. The prevalence of HTGW, as defined elevated waist circumference (90cm or greater for men, 85cm or greater for women) plus elevated triglyceride levels (177mg/dl or higher) was 10.2% in men and 7.3% in women. HTGW prevalence was highly associated with cardiovascular risk factors in both genders. After adjusting for independent variables which were age, total cholesterol, HDL-cholesterol, somking status, education, drinking frequency, physical activity, and carbohydrate intake, there was a greater risk of HTGW with an increased total cholesterol, low high-density lipoprotein cholesterol and increased drinking frequency. Education level in women was identified as a factor associated with HTGW. Conclusions: HTGW can be a simple and convenient predictor for the overaccumulation of abdominal fat and cardiovascular risk. Drink style was associated with the prevalence of HTGW in Korean men and women.
