Aims There is some confusion regarding which anthropometric measurement of adiposity should be used to indicate diabetes, especially for Asians. The present study was to evaluate different indicators of adiposity ( BMI , waist circumference and body fat) with Type 2 diabetes risk among women with prior gestational diabetes mellitus. Methods We performed a cross‐sectional survey in 1263 women with gestational diabetes at 1–5 years after delivery. Logistic regression models were used to estimate the association of BMI , waist circumference and body fat with Type 2 diabetes risk. Results BMI , waist circumference and body fat were all associated with an increased risk of Type 2 diabetes among women with prior gestational diabetes (all P trend < 0.001). After adjustment for waist circumference and body fat, the positive association of BMI with Type 2 diabetes risk became non‐significant and reversed. There was a significantly positive association of waist circumference with Type 2 diabetes risk after adjustment for BMI , and a significantly positive association of body fat with Type 2 diabetes risk after adjustment for both BMI and waist circumference. When the joint effects were examined, the significantly positive associations of waist circumference or body fat with Type 2 diabetes risk were consistent among women with different levels of BMI , and the positive association of BMI and Type 2 diabetes risk was significant among women with gestational diabetes with a waist circumference of ≥ 50% or body fat ≥ 50%. Conclusions BMI , waist circumference and body fat were all associated with an increased risk of Type 2 diabetes, and waist circumference and body fat were better indicators than BMI for Type 2 diabetes risk among Chinese women with prior gestational diabetes.
