Model 1: unadjusted model with hip circumference.

Model 2 controlled for waist circumference.

Model 3 controlled for waist circumference and BMI.

Model 4 controlled for waist circumference, BMI, education, income, occupational status, energy intake, physical activity, current smoker status, alcohol consumption, hypertension, and a family history of type 2 diabetes.
