Purpose: Body mass index (BMI) and waist circumference have been widely used as indices to determine obesity along with waist /height ratio. The purpose of this study was to compare the efficacy of obesity indices which correlate with the metabolic risk factors in adults in Jeju island.
Results: BMI, waist circumference, and waist/height ratio were measured as indices for obesity. Four items (high blood pressure, high fasting glucose, high triglyceride, and low HDL cholesterol) were included as metabolic risk factors. Metabolic high risk group was defined as the sum of the metabolic risk factor score of ≥ 3 (one point per item, if present). Each obesity index was compared to metabolic risk factors.
Results: All obesity indices showed significant correlation with metabolic risk factors. In men, waist circumference had the largest area under the curve (AUC)s for the identification of high risk group (0.729, P < 0.001). However, In women, waist/height ratio had the largest AUCs (0.803 , P < 0.001). People with more than 3 metabolic risk factors with normal waist circumference were also analyzed. In both men and women, Waist/height ratio had the largest AUCs (men 0.706, P = 0.005, women 0.785, P = 0.010).
Conclusions: Waist/height ratio was the most significant index for screening metabolic high risk group in women. In normal waist group, waist/height ratio in both men and women respectively served as effective index for screening metabolic high risk group.
