Vitamin D status of Thai premenopausal women.
Vitamin D insufficiency of Thai elderly women in urban area were higher than in rural area because of the difference in life style. Until now there are no any evidences about vitamin D status in Thai premenopausal women. This study was the multicenters study from 5 provinces of Thailand which cover all region of Thailand except southern area. The mean (SE) of calcidiol level of Thai premenopausal women was 29.09 (0.42) ng/ml, and with the cut point of < or = 35 ng/ml; the prevalence of vitamin D insufficiency was 77.81%. Chiang Mai had lowest calcidiol level (25.09 ng/ml) and had highest PTH, and bone resorption markers. The prevalence of vitamin D insufficiency was highest in Khon Kaen (88.78%) and Chiang Mai (84.62%) province respectively. Life style modification to expose more sunlight should be advised for increasing the serum vitamin D and lowering the risk of osteoporosis.
