乌鲁木齐地区2711例骨密度调查研究

目的了解新疆乌鲁木齐地区正常汉族人群骨密度(BMD)的变化规律和骨质疏松症(OP) 的患病率。方法应用法国DMS公司生产的CHALLENGER型双能X线骨密度仪对乌鲁木齐地区汉族人群共2711名20～80岁居民进行腰椎2～4及股骨近端的骨密度测定。结果乌鲁木齐地区汉族人群男性、女性的腰椎及股骨近端的BMD峰值均出现在20～29岁年龄组,峰值后随着年龄的增长,而骨密度BMD降低,女性在50～59岁明显加速下降,男性没有加速下降现象。乌鲁木齐地区40岁以后OP患病率男性28．3％,女性OP患病率45．2％。男女性50～59岁以上,组间患病率有显著差异(P<0．05)。结论通过对乌鲁木齐地区汉族人群的骨密度变化规律及患病率研究, 为乌鲁木齐地区汉族人群的骨质疏松症诊断及治疗提供客观有效的依据。

Study on bone mineral density of 2711 residents in Urumqi

Obiective To investigate the changing patterns of hone mineral density and the incidence of osteoporosis in Urumqi residents. Methods BMD values of lumber spine and proximal femur were determined by dual energy X-ray absorptiometry in 2711 residents aged 20 to 80. Results The peak values of BMD were detected in 20-29 age group and declined gradually afterwards. The female BMD showed a sharp decline in 50-59 age group while the male did not. The incidence rate of osteoporosis after 40 years old was 28. 3% (male) and 45. 2% (female) , respectively. Significant difference was found between male and female in age group of 50-59 (P>0. 05) . Conclusions This study provides a subjective and effective evidence for diagnosis and treatment of osteoporosis in Urumqi region.
