Abstract

Background

The International Diabetes Federation consensus recently proposed a new definition for the diagnosis of metabolic syndrome, incorporating ethnically specific waist circumference (WC) cutoff points.

Objective

We investigated the ethnically appropriate WC cutoff values for central obesity in Korean adults to predict increased risk of elevated triacylglycerol, reduced HDL cholesterol, elevated blood pressure, elevated fasting plasma glucose, or two or more of these factors.

Design

We used data from 6561 adults, aged 20–80 years, who participated in the Korean Health and Nutritional Examination Survey of 1998, a cross-sectional health survey of a nationally representative sample of Koreans.

Results

Based on the receiver operating characteristic curve analysis, the WC value for predicting metabolic risk factors in Koreans was about 85cm for men and 80cm for women. The odds ratio for the risk of two or more metabolic risk factors increased abruptly in men with WC≥90cm and women with WC≥85cm. The 80th percentile for WC in the Korean population was 90cm for men and 86.5cm for women. Thus, the appropriate WC cutoff point for central obesity in Koreans was determined to be 90cm for men and 85cm for women.

Conclusions

Based on our criteria, the prevalence of central obesity was 19.8% in Korean men and 24.5% in Korean women. These findings suggest the applicability of ethnically specific cutoff points for WC in assessing central obesity.
