| 目的 探讨人体瘦组织对骨密度的影响。方法 将160例进行DXA（Dual-energy x-ray absorptiometry 双能X线骨密度吸收仪）骨密度和身体成分分析的患者作为研究对象，根据瘦组织指数将女性和男性患者平分为高瘦组织指数组和低瘦组织指数组，比较二组的股骨颈、全髋和腰椎骨密度。结果 54例高瘦组织指数组女性瘦组织指数为16.9942±1.2634 kg/m2， 54例低瘦组织指数组女性瘦组织指数为14.2981±0.7956 kg/m2；26例高瘦组织指数组男性瘦组织指数为19.5200±1.0863 kg/m2，26例低瘦组织指数组男性瘦组织指数为16.0654±1.4077 kg/m2。男女高瘦组织指数组的股骨颈、全髋和腰椎骨密度均显著高于低瘦组织指数组（P<0.05）。结论 高瘦组织指数女性和男性患者均具有较高的股骨颈、全髋和腰椎骨密度。 |

| Objective To study the effect of lean mass on bone mineral density (BMD). Methods BMD measurement was performed using dual-energy X-ray absorptiometry and body composition was analyzed in 160 patients. The females and males were divided into the groups with higher lean mass index (LMI) and the group with lower LMI according to the lean mass/H2. BMD of the femoral neck, total hip, and lumbar spine was compared between higher LMI group and lower LMI group. Results The lean mass/H2 was 16.9942±1.2634 kg/m2 in 54 female patients with higher LMI and 14.2981±0.7956 kg/m2 in 54 female patients with lower LMI, and 19.5200±1.0863 kg/m2 in 26 male patients with higher LMI and 16.0654±1.4077 kg/m2 in 26 male patients with lower LMI. The females and males with higher LMI had higher BMD at femoral neck, total hip and lumbar spine than that in the patients with lower LMI (P<0.05). Conclusion The females and males with higher LMI have higher BMD at the femoral neck, total hip, and lumbar spine. |
