Relationship between Body Composition with Bone Mineral Density of Femur in Athletic and Nonathetic Premenopausal Women

Introduction and Aims: Osteoporosis is a skeletal system disease and the major consequence of this disease is bone fractures. The purpose of this study was to describe the relationship between body composition and bone mineral density of femur in athletic and nonathletic premenopausal women.
Recent research has the type of correlation descriptive. Its statistic sample was consisting of 15 active and 15 non active premenopausal women. Fat Mass (FM) and Lean Body Mass (LBM) and Bone Mineral Density (BMD) of femur were measured by DEXA machine. Collected data were analyzed by SPSS v.16 software and Pearson correlation test and regression in the level of P≤ 0.05.
The results of presents study showed that there is significant relationship between LBM with BMD of femoral neck (P=0.003) and also total femur (P=0.03) in athletic premenopausal women group. But also a significant relationship was observed between total body FM and LBM with BMD of femoral neck (P=0.02, P=0.007) and also trochanter (P=0.009, P=0.01) and total femur (P=0.007, P=0.04) in non-athletic premenopausal women.
LBM can be considered as strong predictor of BMD of femoral neck in athletic premenopausal women but FM and LBM is as determinant factor of BMD of femoral neck in non-athletic premenopausal women and FM is stronger predictor compered to LBM in the recent group.
