大连地区1112名正常人群骨密度测定结果分析

Determination of bone mineral density by absorptiometry in normal people in Dalian

目的 为了了解大连地区正常人群骨密度的水平和特点 ,以便为本地区骨质疏松症的研究提供有益的参考数据。方法 本研究应用法国DMS公司生产的Challanger双能X线骨密度仪 ,对大连地区 1112名正常人的腰椎和股骨近端骨密度进行了测定。结果 男性各部位骨峰值年龄在 2 0～ 2 9岁 ;女性Ward氏区骨峰值年龄在 2 0～ 2 9岁 ,其他部位骨峰值年龄在 30～ 39岁。女性腰椎前后位、骨股近端峰值骨量大于男性相应部位的峰值骨量 ,腰椎各部位BMD与股骨近端BMD存在相关性 (P <0 0 5 )。结论 男性各部位骨峰值年龄在 2 0～ 2 9岁 ;女性Ward氏区骨峰值年龄在2 0～ 2 9岁 ,其他部位骨峰值年龄在 30～ 39岁。女性腰椎前后位、股骨近端峰值骨量大于男性相应部位的峰值骨量 ,有显著差异 (P <0 0 5 )。腰椎各部位BMD与股骨近端BMD存在相关性 (P <0 0 5 ) ,但r值在 0 1～ 0 3之间 。

Objective\ To evaluate bone mineral density of normal people in Dalian,providing useful data for the study of osteoporosis. Methods\ Bone mineral density of the lumbar spines and hip in 1112 healthy subjects was measured with DMS Challenger dual\|energy X\|ray absorptiometer made in France. Results and Conclusions\ The peak bone mass of lumbar vertebrae and hip occurred in the age group 20～29 of males;that of Ward's triangle occurred in the age group 20～29 and that of other areas occurred in the age group 30～39 of females.The peak bone mass of lumbar vertebrae and hip of females are much higher than that of males,the differences being significant( P <0\^05).BMD of lumbar spines is related to BMD of hip for both sexes( P <0 05),but r =0 1～0 3;the measurements of these two sites can not be replaced each other.
