To test whether in Moroccan healthy postmenopausal women, levels of plasma total homocysteine (tHcy), folate, and vitamin B12 are related to BMD. A total of 188 volunteer postmenopausal women were recruited from our blood taking center between April 2008 and December 2008. Each subject completed a standardized questionnaire designed to document putative risk factors of osteoporosis. Bone mineral density was determined by a Lunar Prodigy Vision DXA system, and blood samples for plasma tHcy, folate, vitamin B12, and serum parathyroid hormone (PTH) were taken. Comparison between women with osteoporosis, osteopenia and normal BMD showed that the osteoporotic women were significantly older, had lower weight and height than the women of the other groups. Plasma tHcy was significantly higher in the osteoporotic group. Levels of tHcy were inversely related to BMD at the lumbar spine, at the total hip and plasma vitamin B12 and positively related to age and creatinine. Multiple regression analysis showed that age and BMI were the main predictors of BMD at the lumbar spine, whereas the main predictors of BMD at the total hip were age, BMI, plasma tHcy, and plasma vitamin B(12). tHcy and vitamin B12 are independent risk factors for osteoporosis in Moroccan healthy postmenopausal women.
