| 目的 分析老年男性的腰椎 2-4(L2-4)、股骨颈(Neck)、大转子(Troch)和粗隆间(InterTro)的骨密度(BMD)，探讨老年男性肥胖与骨密度的关系。方法 以我院 273 名年龄 60 ～75 岁的老年男性为研究对象，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，分析老年男性肥胖与骨密度的关系。结果老年男性各部位的骨密度随年龄的增长而降低，老年男性 70 ～75 岁组股骨颈和粗隆间的骨密度均低于 60 ～64 岁组(P ＜0. 01)。老年男性按不同年龄分组发现，肥胖者不同部位的骨密度均高于对照者(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，老年男性肥胖者骨密度较正常体型者高，提示肥胖对骨密度有保护作用。 |

| Objective To analyze the bone mineral density (BMD) of the lumbar spine (L2-4)，the femoral neck (Neck)，the greater trochanter (Troch)，and the intertrochanter (InterTro) in elderly men，and to explore the relationship between obesity and BMD in elderly men． Methods The research subjects were 273 elderly men from 60 to 75 years old． The subjects were divided
into the control group and the obese group according to BMI． BMD of the lumbar spine，Neck，Troch，and InterTro was measured using dual energy X-ray absorptiometry． The relationship between obesity and BMD in elderly men was analyzed． Ｒesults BMD of different sites in elderly men decreased with the increase of age． BMD of the Neck and InterTro decreased significantly in 70-75 years old group comparing to those in 60 －64 years old group (P ＜ 0. 01)． BMD of subjects in the obese group was significantly higher than that in the control group in different age groups in elderly men (P ＜0. 05 or P ＜0. 01)． Conclusion Age and BMI are important factors of BMD． BMD of subjects in the obese group is significantly higher than that in the control group，suggesting that obesity has protective effect on BMD． |
