目的了解武汉市正常人群骨密度的变化特点，分析骨密度及骨质疏松变化规律，提高对骨质疏松症诊断的可预测性和可靠性。方法采用美国生产的双能X线骨密度仪对进行体检的2285人进行骨密度测定，其中男性1410例，女性875例。检测部位为第1～4腰椎椎体。年龄20～79岁，按年龄、性别进行分组以10岁为一个年龄段进行统计，分别计算各年龄段的骨密度T值、低骨量及骨质疏松发病率，并用SPSS软件比较各年龄段之间的差异性。结果男性腰椎骨密度T值峰值出现在20～29岁，峰值为-0．440±0．7198，随后随着年龄的增长缓慢下降，60岁以后男性骨质疏松发病率明显增加。女性腰椎骨密度T值峰值出现在30～39岁，峰值为-0．1173±0．8198，40～49岁年龄段缓慢下降，在50岁以后呈加速下降趋势。女性在50岁以后骨质疏松发病率明显增加。结论随着年龄的增长，男女性骨密度均呈下降趋势，男性60岁以后，女性50岁以后骨质疏松患病风险增大。

Objective To observe the chacracteristics of lumbar spine BMD ( Bone Mineral Density ) in gen-eral population in Wuhan City ,and analyse the variation of bone density and osteoporosis in order to improve the pre-dictability and reliability of the diagnosis of osteoporosis .Methods BMD was measured in 2285 cases (1410 men, 875 women),aged 20-79 years from Wuhan area using dual-energy X-ray absorptiometry(USA) during the year of 2012 .The measurement sites included lumbar vertebrae 1 to 4 lumbar spine .People were divided into subgroups ac-cording to gender and sex by 10-year age interval .Results The peak of male lumbar spine BMD T values appeared in 20-29 years,valued( -0.440 ±0.7198),then declined slowly with increase of age ,and the incidence of osteo-porosis in men increased significantly after the age of 60.The peak of female lumbar spine BMD T values appeared in 30-39 years,valued(-0.1173 ±0.8198),then declined slowly in (40-49) years,and declined acceleratively af-ter the age of 50 years old.The incidence of osteoporosis in women increased significantly after the age of 50 years old.Conclusion BMD in men and women showed a downward trend with age increase .The risk of osteoporosis in-creased after the 60-year-old in men ,50-year-old in women .
