目的了解年龄、体重指数及运动与否对中老年男性骨密度的影响.方法选择在北京协和医院体检中心做健康体检的40岁以上的男性体检者321人,分别统计并分析不同年龄、体重指数、运动锻炼情况的体检者在腰椎、股骨颈及股骨大粗隆的骨密度的不同.结果股骨颈处骨密度40～49岁组为(0.970±0.146) g/cm2；50 ～59岁组为(0.954±0.106) g/cm2,≥60岁组为(0.907±0.126) g/cm2,50 ～ 59岁组与40 ～ 49岁组,≥60岁组与40 ～ 49岁组比较,差异均有统计学意义(t分别为1.52,1.82；P ＜0.01)；50～59岁组与≥60岁组比较差异无统计学意义(t=1.78,P＞0.05)；不同年龄体检者在L2～L4、股骨大粗隆处骨密度比较差异均无统计学意义(P＞0.05)；体重指数20.0 ～23.9组与≥30.0组比较股骨颈、股骨大粗隆处骨密度比较差异有统计学意义(t分别为1.31,1.42;P＜0.01),体重指数24.0 ～29.9组与≥30.0组比较L2～L4、股骨颈、股骨大粗隆处骨密度差异均有统计学意义(t分别为1.40,1.56,1.43;P ＜0.05)；体重指数20.0～23.9组与24.0～29.9组比较股骨大粗隆处骨密度差异有统计学意义(t=1.67,P＜0.01)；运动组与非运动组比较,无论腰椎还是股骨上段各部位的骨密度值运动组都高于非运动组,两组比较差异有统计学意义(P＜0.01).结论中老年男性的年龄对骨密度的影响不大,只有股骨颈的骨密度值受年龄因素的影响；BMI与骨密度有相关性,但在不同年龄段与各部位骨密度的相关性不同；运动能有效的维持骨量,对中老年男性的骨密度有很好的保护作用.

Objective To explore the effect of age,BMI and exercise on middle-aged men's bone density.Methods 321 men who were above 40 years old and had health examination at physical examination center,Peking Union Medical College Hospital have been included in the research.Bone density of lumbar vertebra,neck of femur and thigh-bone of men with different ages,BMI and exercises were analyzed.Results Bone density of neck of femur was (0.970 ± 0.146) g/cm2 in the group of men between 40 and 49 years old,(0.954 ± 0.106) g/cm2 in the group of men between 50 and 59 years old,and (0.907 ± 0.126) g/cm2 in the group of men older than 60.The differences between Group 50-59 and Group 40-49,as well as between Group older than 60 and Group 40-49 were statistically significant (t =1.52,1.82,respectively; P ＜ 0.01).There was no statistically significant difference between Group older than 60 and Group 50-59 (t =1.78,P ＞ 0.05).The difference of bone density of L2-L4 and thigh-bone of men with different ages was not significant (P ＞0.05).Bone density of neck of femur and thigh-bone in the group of men whose BMI was between 20.0 and 23.9 was statistically different from that in the group of men whose BMI was no less than 30.0 (t =1.31,1.42,respectively; P ＜0.01).Bone density of L2-L4,neck of femur and thigh-bone in the group of men whose BMI was between 24.0 and 29.9 was statistically different from that in the group of men whose BMI was no less than 30.0 (t =1.40,1.56,1.43,respectively ;P ＜ 0.05).Bone density of thigh-bone in the group of men whose BMI was between 20.0 and 23.9 was statistically different from that in the group of men whose BMI was between 24.0 and 29.9 (t =1.67,P ＜ 0.01).Both bone density of lumbar vertebra and thigh-bone were higher in the exercise group than in the non-exercise group,and the differences were statistically significant (P ＜0.01).Conclusions Middle-aged men' s age has little influence on their bone density,and only bone density of neck of femur is affected by age.BMI has some correlation with bone density,but men with different ages have different bone density of every part.Exercise can effectively maintain bone mass,thus is an important tool for middle-aged men to protect their bone density.
