Model 1 is adjusted for age (years), examination year and energy intake (kcal/day)
Model 2 is adjusted for Model 1 plus smoking (never smoker, previous smoker, current smoker < 20 cigarettes/day and current smoker ≥ 20 cigarettes/day), body mass index (kg/m2), leisure-time physical activity (kcal/day), education (years), marital status (married vs other), income (euros/year), and family history of diabetes (yes/no)
