Abstract

 Background: Introduction: Low BONE MINERAL DENSITY (BMD) is a major risk factor for osteoporotic fracture. There are emerging evidences, that micronutrients and macronutrients may play a protective role against age related bone loses. In this study the relationship between DIETARY CALCIUM INTAKE and BONE MINERAL DENSITY in adult population was investigated.Methods: A total of 1028 healthy men and women, aged 20-72 years, were randomly selected from 13 clusters in Bushehr port. DIETARY CALCIUM INTAKE with a validated FFQ was evaluated. Dual-energy X-ray absorptiometry (DXA) was used to determine the BONE MINERAL DENSITY (BMD) of the lumbar spine (L2-L4), distal third of radius, and proximal femur. Serum degradation products of the C-TERMINAL TELOPEPTIDES OF TYPE I COLLAGEN (CTX), and OSTEOCALCIN were measured by highly specific ELISA methods.Results: There was significant positive age- adjusted linear correlation between DIETARY CALCIUM INTAKE and femur neck BMD (r=0.06, p<0.05), femur ward’s triangle BMD (r=0.07, p=0.01), and femur trocanter BMD (r=0.06, p<0.05). Negative age-adjusted linear correlation between DIETARY CALCIUM INTAKE and OSTEOCALCIN (r=-0.07, p<0.05) in adults population were significant.Conclusion: It is concluded that a high DIETARY CALCIUM INTAKE has protective role against osteoprotc fracture and is supported by reduction of OSTEOCALCIN, a turn over marker in people who had used more calcium.
