| Abstract |
Objective
The aim of this study was to investigate the relationship between body composition and bone mineral density in middle aged women.
Materials and Methods: Bone mineral density (BMD) of lumbar spine and both femur neck was measured with dual-energy X-ray absorptiometry (DXA) in 89 middle-aged women aged between 38 and 77 years old. Lean and fat mass of the arms, trunk, legs, total body, were measured at the same time with DXA.
Results
Android fat mass was increased with aging (p<0.05). Body weight has positive correlation with BMD of lumbar and femoral neck, especially right side of femur. However, regional fat mass did not show any significant correlation with lumbar or both femur neck BMD. Lean body mass of left leg, left trunk, left total, right leg, right trunk, right total, arms, legs, trunks was positively correlated with BMD of the lumbar and both femur neck, respectively.
Conclusion
BMD was decreased and android fat mass was increased by aging in middle-aged women. However, Lean body mass rather than fat mass is more important determinant of axial bone mineral density.
