Factors associated with vitamin D status in Australian women

(1) The aim of this study is to determine the impact that latitude, skin type, diet and sun exposure have on vitamin D status of healthy Australian women and to explore the rates and potential causes of deficiency. Serum 25(OH)D was measured through liquid chromatography mass spectrometry, dietary intake through a 4-day food record analysed using FoodWorks 10, bone density through dual energy x-ray absorptiometry and sun exposure through a polysulphone film badge worn for 4 days. Given the increased risk of melanoma from excessive sun exposure, targeted advice towards vitamin D-rich food sources may be helpful for those individuals with poorer vitamin D status.
