| 目的 分析绝经后妇女的腰椎2-4( L2-4)和股骨颈（Neck)、大转子(Troch)、粗隆间（InterTro)的骨密度（BMD)，探讨绝经后妇女肥胖与骨密度的关系。方法 以我院269名年龄45 -75岁的绝经后妇女为研究对象，计算体重指数将研究对象分为肥胖组和对照组，采用双能X线骨密度仪检测腰椎、股骨颈、大转子、粗隆间的骨密度，分析绝经后妇女肥胖与骨密度的关 系。结果 肥胖组绝经后妇女不同部位的骨密度均高于对照组(P <0.05或P <0. 01)。绝经后妇女各部位的骨密度随年龄的增长而降低，各年龄组间的骨密度有显著性差异(P <0.05或P <0. 01)。结论 年龄和体重指数是影响骨密度的重要因素，绝经后妇女肥胖者骨密度较正常体型者高，肥胖者可能通过负重等作用，延缓绝经后妇女骨密度的下降。 |

| Objective To analyze bone mineral density (BMD) of the lumbar spine (L2-4 )，the femoral neck (Neck)，the greater trochanter (Troch)，and the intertrochanter (InterTro) in postmenopausal women，and to explore the relationship between obesity and bone mineral density in postmenopausal women. Methods The research subjects were 269 postmenopausal women aging from 45 to 75 years old. The subjects were divided into control group and obese group according to their BMI. BMD of the lumbar spine，the femoral neck，the greater trochanter，and the intertrochanter were measured using dual energy X-ray absorptiometry. The relationship between obesity and bone mineral density in postmenopausal women was analyzed. Results BMD of subjects in obese group were significantly higher than those in the control group (P < 0. 05 or P <0. 01). BMD of different sites in postmenopausal women decreased with the increase of age. BMD was significantly different among all age groups (P <0. 05 or P < 0. 01). Conclusion Age and BMI are important factors for BMD. BMD of subjects in obese group is significantly higher than that in control group. Obesity may prevent BMD decrease in postmenopausal women through many factors such as greater physical loading. |
