title: Prevalence of hypovitaminosis D in elderly women living in urban area of Khon Kaen province, Thailand.
abstract: This study included 106 volunteer elderly women who were living in an urban area of Khon Kaen province. The mean (+/-SD) of age and of serum 25(OH)D concentration of these elderly women was 69.42 (+/-6.77) years and 33.32 (+/-7.14) ng/ml respectively. There was a significant inverse relationship between serum 25(OH)D and PTH concentration. Serum PTH concentration started to increase steeply when serum 25(OH)D concentration declined < or = 35 ng/ml and increased significantly when serum 25(OH)D concentration declined < or = 30 ng/ml. Furthermore mean (+/-SD) of serum 25(OH)D concentration in the group of osteopenia and osteoporosis of femoral neck was 35.25 (+/-6.77) and 30.92 (+/-6.49) ng/ml respectively. As a result, the prevalence of hypovitaminosis D in these selected elderly women would be at least 34.9 per cent, or as high as 65.1 per cent.
