1 Model is adjusted for age groups, BMI (normal, overweight, obesity), alcohol (g/day), leisure time physical activity (active ≥ 30 min/day) and smoking (never, smoking, former smoker). 2 Model is adjusted for age groups, BMI (normal, overweight, obesity), alcohol (g/day), leisure time physical activity (active ≥ 30 min/day), smoking (never, current, past), VitD intake and 25-hydroxivitamin D levels. a Low, medium and high VDBP category levels were defined by tertiles. * Minimum–maximum value of each category.
