玉溪地区2593例男性骨密度调查分析

目的通过2593例玉溪地区男性骨密度测定,为了解玉溪地区男性骨密度(BMD)正常值及峰值骨量,分析骨质疏松症(Osteoporosis,OP)的发病规律,为OP的预防和治疗提供帮助。方法采用日本Aloka生产的DCS-600EX型骨密度仪,检测非优势侧前臂远端三分之一处BMD。将2593例检测结果以5岁为1个年龄段进行统计学分析BMD均值,计算出各年龄组的OP患病率。结果玉溪地区男性BMD峰值为0.588±0.081(g/cm2),其BMD峰值出现在30～岁年龄段。各年龄段OP的患病率为20～岁7.41%、25～岁11.70%、30～岁9.68%、35～岁7.49%、40～岁13.84%、45～岁10.93%、50～岁17.20%、55～岁23.59%、60～岁30.22%、65～岁44.32%、70～岁42.34%、75～岁48.94%、80～岁38.89%。结论玉溪地区男性BMD30岁前随年龄增加而增加,BMD峰值出现在30～岁,峰值为0.588±0.081(g/cm2),其后BMD测定值随年龄增加开始逐渐下降,OP的患病率随年龄增加而增加,但80～岁年龄组反而有所下降。

Analysis BMD measurement of 2593 men in Yuxi area

Objective The BMD of 2593 men in Yuxi area were determined for investigating normal reference data of male bone mineral density (BMD) and peaking bone mass and analyze regularity of pathogenesis of osteoporosis,and provide scientific basis for prevention of OP.Methods The BMD of the distal one third of ulna of norr dominant arm were determined by DCS-600EX BMD detector produced by Japanese Aloka Corporation.2593 objects were divided into different groups by 5 years,measure their BMD and the prevalence rate of OP.Results The peak value of bone mineral density was 0.588±0.081(g/cm~2)in male,and that was showed in the age group of 30-.The prevalence rate of OP was 7.41% in 20-,11.70% in 25-,9.68% in 30-,7.49% in 35-,13.84% in 40-,10.93% in 45-,17.20% in 50-,23.59% in 55-,30.22% in 60-,44.32% in 65-,42.34% in 70-,48.94% in 75-,38.89% in 80-.Conclusion In Yuxi area,the male BMD increased with ageing before 30 years old.The peak value of bone mineral density was 0.588±0.081 (g/cm~2),and that was showed in the age group of 30-,and then,the BMD decreased with ageing.The incidence of OP increased with ageing,but that decreased in 80-.
