摘要: 目的 确定几种常见生活因子对中老年男性骨密度(BMD)的影响,以便指导骨质疏松症的防治工作。方法 对在武汉同济医院高干病房进行体检的286例50～79岁的汉族中老年男性采用问卷方法进行生活饮食习惯等情况调查;用双能量X线骨密度测量仪(DEXA)测定腰椎及股骨颈BMD值,并进行统计分析。结果 (1)将平均每天摄钙量按从低至高分A、B、C3组,其中年龄在60～69岁的C组腰椎及股骨颈BMD明显高于A组(P<0.01),与B组比较其股骨颈BMD差异也有统计学意义(P<0.05);70～79岁年龄的C组腰椎及股骨颈BMD与A、B组比较均有很大差距,差异有统计学意义(P<0.05)。(2)不同的蛋白质摄入量及饮酒对骨密度的影响不明显。(3)吸烟对骨密度有较大影响,吸烟组股骨颈BMD低于非吸烟组(P<0.05)。(4)运动对骨密度有较大影响,运动组股骨颈BMD高于非运动组(P<0.05)。结论 增加钙的摄入有助骨密度的提高;蛋白质的摄入情况以及饮酒对骨密度影响不大;吸烟促进骨密度的降低;运动有助于骨密度的提高。Abstract: Objective To evaluate the effects of lifestyle factors on bone mineral density(BMD)of elderly man for the prevention of osteoporosis.Methods A total of 286 healthy man aged 50-79 were interviewed to obtain information on their lifestyle.The subjects were divided into three groups(A,B,C)according their daily in take of calcium from low to high and their spinal BMD and femoral neck BMD were dete rmined with DEXA scan.Results The spinal BMD and femoral neck BMD of group C were higher than that of group A(P<0.01)for subjects at age of 60-69.The man doing physical exercise constantly had higher BMD than those seldom doing(P<0.05).Conclusion The ingestion of abundant calciumis help ful to enhance BMD.Drinking and protein in take have no obvious effect on BMD.Smoking can cause decrease of BMD.Physical exercises is help ful to enhance BMD.
