Model 1: adjustment for age, household income, education level, residential areas, alcohol consumption, smoking, physical activity, energy intake per day, dietary supplement, and duration of breast feeding. Model 2: adjustment for model 1 + body mass index. Model 3: adjustment for model 2 + alkaline phosphatase, ferritin, and 25-hydroxyvitamin D. Ca/P ratio Calcium/phosphorus intake ratio. Results in bold indicate statistical significance at the 0.05 level.
