双能X线骨密度检测2092例临床体会

Dual energy X-ray bone density testing:2092 cases of clinical experience

目的：检测成都市黄田坝地区体检人群骨密度（BMD）随年龄、性别变化的规律,探讨骨质疏松症（OP）BMD诊断标准。方法：应用韩国双能X线骨密度（osteoSys DEXA-3000）仪测量2 092例无继发性骨量减少因素的体检人群腕部BMD值,其中男996例,女1 096例,年龄30~89岁。按年龄分为五组统计分析,同时分别以同性别、同部位峰值减低诊断标准进行分析比较。结果：男女两性BMD值随年龄增长而下降,女性的BMD下降趋势较男性明显,绝经后下降趋势更明显,其中50~59岁和60~69岁年龄组骨量呈快速丢失阶段。结论：为本地区不同性别、各年龄段BMD值及变化特点积累了数据和资料,同时指出由于女性在先天及后天因素的影响下,其OP的发生明显的高于男性,因此骨密度值的监测对人群特别是老年人群、绝经后妇女骨质疏松的预防和治疗有重要的临床意义。

Objective To understand the change of the bone mineral density（ BMD） with age and sex by measuring of check-up crowd in huangtianBa area,and to discuss BMD criteria for the diagnosis of osteoporosis（ OP）.Method Applied Korean dual energy X-ray bone density（ osteoSys DEXA-3000） instrument measured wrist BMD values of 2092 cases without secondary bone loss factors of check-up crowd,1096 women,996 men,age range of 30 ~ 89 years old.Statistical analysis was divided into 5 groups according to age,at the same time with same gender,the peak area was analyzed by reducing diagnostic criteria.Results BMD values along with the age growth declined in men and women,postmenopausal downward trend of women was more obvious than man,and bone mass was lost rapidly in the 50 ~ 59 years old and 60 ~ 69 year old stage.Conclusion This study accumulates data and information for BMD values and its change characteristics of different gender,different age stages in the region.Also points out that because of the influence of the innate and acquirs factors in women,the OP occurs obviously higher than that of men,so the bone mineral density values have important clinical significance in the prevention and treatment of osteoporosis.
