Purpose： The aim of this study was to investigate the correlations between body compositions and bone mineral density in young women and postmenopausal women with low bone mineral density.
Methods： Eleven young women (age, 25.85±1.96 yrs; height, 160.28±2.16 cm; weight, 56.89±9.66 kg) and ten postmenopausal women (age, 25.85±1.96 yrs; height, 160.28±2.16 cm; weight, 56.89±9.66 kg) with low bone density on femur neck were participated in this study. All subjects performed the measure of body composition and BMD on lumbar body and femur neck.
Results： The results were as follows. Percent body fat, waist-hip ratio and body mass index(BMI) were significantly increased in postmenopausal women. BMD in lumbar body and femur neck were significantly decreased in postmenopausal women. There were negative strong correlation between BMD of the femur and age in young women.
There were negative strong correlation between BMD of the femur and age or the years of menopause in postmenopausal women. There were positive strong correlation between BMD of the femur and BMD of lumbar body.
Conclusion： Percent body fat and BMI were more increased in young women than in postmenopausal women. And there were negative strong correlation between BMD and age or the years of menopause in postmenopausal women.
