Core Tip

Core tip: The predictive powers of body mass index (BMI) and waist circumference (WC) were similar in predicting the incidence risk of diabetes in either gender. The cut-off points for predicting diabetes in men and women were different. Defined cut-off points based on maximum sensitivity plus specificity values suggested that in men, BMI of 26.2 kg/m2 and WC of 89.7 cm, and in women, BMI of 28.6 kg/m2 and WC of 84.3 cm would predict Isfahanian population at high risk for developing diabetes.
