Prevalence of hypovitaminosis D in elderly women living in urban area of Khon Kaen province, Thailand.
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.
