双能X线骨密度仪测定83例2型糖尿病人骨密度分析

目的 了解2型糖尿病患腰椎及髋部骨矿物密度的变化。方法 双能X线骨密度仪测定2型糖尿病病人共83例(年龄40—79岁)，其中男性43例，女性40例；健康对照组71例(年龄40—79岁)，男性38例，女性33例。对比分析糖尿病组与同性别同龄正常组的测量结果，另根据病程将糖尿病组分为大于5年及小于5年组，并对2组结果进行分析。结果①糖尿病组与健康对照组比较，腰椎及髋部骨密度差异无显性；②病程大于5年与小于5年的2型糖尿病患间骨密度差异无显性。结论 2型糖尿病是否引起骨矿物密度降低或增高有待进一步研究。

Analysis of bone mineral density in patients with type 2 diabetes mellitus

Objective To investigate the changes of bone mineral density(BMD)in patients with type 2 diabetes mellitus(DM) Methods BMDs of hip and lumbar vertebrae were measured by DEXA in the patients ( n =83, aged 40 79) and in heathy subjects( n =71,aged 40 79) The BMDs of the patients were compared with those of age matched control group The BMDs in patients with a history of type 2 DM more than 5 years and less than 5 years were separately analysed Results The BMDs of hip and lumbar vertebrae in patients with DM had no significant difference, compared with those of control group No significant difference in BMD was found between patients with a history of DM more than 5 years and those less than 5 years Conclusion Whether type 2 DM causes the decrease or increase in BMD needs further study
