*ORs were calculated using multivariate logistic models. All covariates listed were included in the model simultaneously. Serum triglycerides, smoking status included the three models without significant difference not presented.

†Insulin resistance was defined as Matsuda ISI <25th centile in individuals with normal glucose tolerance.

‡Economic development levels were placed into three categories (under developed, intermediate developed and developed).

BMI, body mass index; CNY, Chinese Yuan; IR, insulin resistance; IS, insulin sensitivity; NI, not included in the model.
