*
Adjusted for age, age2, previous and current alcohol drinking, education, occupation and correlations among twin pairs.
a
Pre-diabetes was defined as fasting glucose: 5.6~7.0 mmol/L and/or 2H-OGTT glucose: 7.8~11.1 mmol/L.
b
Joint associations of BMI and central adiposity (%TF and WC) on the risk of pre-diabetes.
c
The associations between central adiposity (%TF and WC) and pre-diabetes stratified by BMI.
d
High %TF defined as highest quartile for entire study population.
