Model 1: age, sex, study site (5 study sites)

Model 2: Model 1 plus education (never or elementary; low; intermediate; high vocational), total energy intake (kcal per day), smoking (never; former; current), physical activity (METs-h per week)

Model 3: Model 2 plus BMI (kg/m²), waist circumference (cm)

*The sensitivity analyses were performed by excluding those with self-reported diabetes at the time of the physical examination (final n = 3954) and the adjustment set is the same as in Model 3
