南通市4174例健康体检者的指骨骨密度调查

目的了解南通市骨质疏松症患病情况，为骨质疏松防治工作提供参考。方法对4174例健康体检者应用Metriscan TM测量非惯用手指指骨的骨密度（BMD）。结果骨密度（BMD）男性T值为（0．123±1．124），正常者为84．6％，骨质减少为12．8％，骨质疏松为2．6％；女性丁值为（-0．101±1．421），正常者为76．9％，骨质减少为12．9％，骨质疏松为10．2％；45岁以上各组，随年龄增加，骨密度T值呈逐渐下降，女性降低幅度高于男性（P〈0．05）。骨质疏松的检出率女性在50岁开始增高，男性≥70岁者明显增高，女性骨质疏松症检出率明显高于男性，差异有统计学意义（P〈0．01）。结论BMD测量可及早检出骨质疏松，而指骨BMD是一种简便易行的方法。骨质疏松症多见于中老年女性，应加强防治。

Investigation of Bone Mineral Density in 4174 People of Physical Examination in Nantong

Objective The aim of this study was to investigate the bone mineral density（BMD） of adults＇ finger bone in order to study the incidence of osteoprosis and provide scientific basis for prevention and treatment of osteoprosis. Method MetriscanTM was used to determine the bone mineral density of adults finger in 4 174 people. Results Among them,level of T was （0. 123±1. 124） in men group. There were 84.6 % of normal level and 12.8% of osteopenia and 2.6% of osteoprosis; level of T was （-0. 101± 1. 421） in women group that there were 76.9% of normal level and 12.9% of osteopenia and 10.2% of osteoprosis. Among people aged over 45, level of T and BMD were decreasing while age was increasing. The decreasing rate was significantly higher in women than in men （P〈0.01）. The osteoporosis detection rate for women starts to increase after 50 year-old,and men＇s osteoporosis detection rate increases significantly after the age of 70. The incidence of osteoprosis was significantly higher in women than in men（P〈0.05）. Conclusion The incidence of osteoprosis is significantly higher in old women than in old men. Effective prevention and treatmant is to be enhenced.
