This study of 3055 postmenopausal women (aged 50–70 y) assessed serum vitamin D [25(OH)D] and potential predictors of 25(OH)D levels. 57.1% of the women had deficient levels of 25(OH)D. Calendar season, waist circumference, physical activity, race-ethnicity, sun exposure, and age were variable predictors of of vita…min D status but vitamin D intake from diet and supplements accounted for the greatest amount of explainable variation.
