Model 1 was crude

Model 2 was adjusted for age and gender

Model 3 was additionally adjusted for smoking, physical activity, education levels, occupation status, total energy intake, family history of diabetes, family history of cardiovascular disease (all variable that adjusted was at baseline)

Model 4 was additionally adjusted for BMI at baseline
