摘　　要：目的通过对使用DTX-200骨密度仪进行前臂尺桡骨骨密度人群调查资料的统计分析,获得鄂西北地区本地人群的骨密度（BMD）正常值及骨质疏松患病率,并对资料的年龄组分布特点进行分析。方法采用美国Osteometer MediTech公司的DTX-200骨密度仪,对鄂西北地区的本地籍人群1957人（男性959人,女性998人）进行前臂尺桡骨远端的BMD检查,按年龄组进行平均值和标准差的计算,根据30～39岁年龄组计算男女骨峰值。结果①男性前臂远端骨峰值为（0.572±0.037）g/cm^2;女性为（0.502±0.041）g/cm^2。男女BMD均在30～39岁组达到高峰。②各年龄组均值显示：女性15～19岁组BMD达到峰值的93%,而男性15～19岁组只达到79%;女性60～69岁组BMD降到峰值的76%,而男性降到88%;20岁以前,男女BMD差别较小;在达到峰值的年龄组,男女BMD差别较大。结论①按30～39岁年龄组统计计算骨峰值比较合理。②20岁以前女性比男性BMD增加的快一些;而中老年以后女性BMD降低得也更早、更快。③骨密度达到峰值以后随着年龄的增长而下降,骨质疏松（OP）发病率也随之增加,同年龄组女性骨质疏松发病率明显高于男性。Objective The normal values of bone mineral density （BMD） and the rate of people diagnosed with osteoporosis in the northwest of Hubei province were obtained by using DTX-200 bone density instrument for statistics and analysis of the survey data of people with ulna and radius to distal forearm bone mineral density and then got the feature of age groups. Methods The check of BMD of ulna and radius to distal forearm on 1957 local nationals in the northwest of Hubei Province,including 959 men and 998 women, were conducted with DTX bone densitometer produced by the American company named Osteometer MediTech. The mean values and standard deviations（SD）of the data of measurement were calculated by age groups. And the bone peak values（BPV） were calculated in age group of 30 - 39. Results O The BPV of radius and ulna in men were 0.572 ± 0.037 ; and those in women were 0.502 ± 0.041. BMD at both men and women 30 - 39 years old group reached a peak. （2） Average of all age groups show that the 15 - 19-year-old female group to reach the peak BMD of 93%, but only 79 % in men ; BMD of women 60 - 69 years old group dropped to 76 % of peak, but only 88 % in men. Before the age of 20, the difference of BMD between men and women was slight, but it became greater in the age groups of peak values. Conclusions （1） It is reasonable to obtain the BPV from age group of 20 - 39. （2） The growth of BMD is quicker in women before the age of 20 than in men of that age. However, the BMD drops more early and quickly in old women than in old men.（3）The BMD declined with the increase of age after peak values, the incidence of osteoporosis the also increased, and in the same age group, the incidence of female osteoporosis was significantly higher than male.
