Relationship between dietary calcium with CTX and bone mineral density in non active post-menopausal women

Osteoporosis is a public health problem that can affect on life in postmenopausal women. Irreparable consequences and prevalence of inactive people are also more than ever active. Evidence indicating a protective effect of calcium on bone mineral density in growing old. In this study the association between dietary calcium, and bone mineral density in postmenopausal women and disable administrative CTX markers we examined. In this study, 117 postmenopausal women 52 to 62 years participated voluntarily. Assessed by food frequency questionnaires. Bone mineral density areas by dual X-ray absorptiometry of 2 to 4 lumbar spine, a third of the distal forearm and femoral neck, and the C-terminal telopeptide of collagen type (CTX) were measured by ELISA. A no significant association between dietary calcium and bone mineral density of the lumbar spine and forearm were observed. But between dietary calcium and bone mineral density of the femoral neck, there was a significant relationship (P <0/05, r = 0/6). Also, there wasn’t found significant relationship between dietary calcium and urinary CTX.
