【摘要】 目的　为探索中老年人骨密度 ( BMD)变化规律及其骨密度值减少的百分率 ,为骨量减少和骨质疏松症的诊断治疗提供科学依据。方法　对 4 5～ 84岁的 651例男性中老年人 ,采用 BMD- 4 0 0型骨密度仪测量前臂中远端 1/ 3和超远端 1/ 10部位的 BMD,按 5岁为一年龄组计算骨量及其丢失的百分率。结果　两部位的 BMD值随年龄增长而逐渐下降 ,BMD累积丢失率 1/ 10部位高于 1/ 3部位。结论中老年人随年龄增长 ,骨密度下降率逐渐增加 ,骨矿含量是诊断骨质疏松症和治疗前后判断疗效的主要依据更多还原

【Abstract】 Objective\ To study the regularities of bone mineral density distrubution in middle\|aged and old peoble and find reliable criterion for the diagnosis of osteoporosis.Methods\ Six hundred and fifty\|one midlle\|aged and old males were measured for the bone mineral density at the 1/3 and 1/10 sites at the distal part of forearm,and the percentages of bone mineral loss were calculated every 5 years of age. Results \ The bone mineral densities decreased with the inrease of age,but bone mineral density at 1/10 stie was higher than that at 1/3 site.Conclusion\ Bone mineral density decreases gradually with the increase of age in middle\|aged and old people,bone mineral contents can be used as the criterion for the diagnosis of osteoporosis and evaluation of therapeutic effects.更多还原
