摘要
目的了解北京城区居民骨密度(BMD)的变化规律和骨质疏松症(0P)的患病率。方法应用法国MEDILINK公司生产的OSTEOCORE1型双能X线骨密度仪对北京市城区3285名20～89岁人群进行股骨近端及腰L2～L4椎的BMD测定。结果北京市城区男、女性人群的股骨近端及腰椎的BMD峰值均出现在20～29岁年龄组,峰值后随着年龄的增长骨密度BMD降低,女性在50～59岁BMD下降明显加速,男性没有出现下降加速现象。北京市城区中国人40岁以后OP患病率男性23.19%,女性OP患病率28.7%。结论通过对北京市城区中国人群的BMD变化规律及患病率研究,为北京市城区中国人群的骨质疏松症预防、诊断及治疗提供客观有效的依据。
Objective To investigate the pattern of bone mineral density （BMD） and the incidence of osteoporosis in Beijing urban residents. Methods BMD values of the lumber spine 2-4 and the proximal femur were determined using dual-energy X-ray absorptiometry （Medilink, France） in 3285 residents aged from 20 to 89 years old. Results The peak BMD values of the proximal femur and the lumbar vertebra appeared in the 20-29 age groups in both males and females. BMD then declined gradually thereafter along with age growth. BMD in females showed a sharp decline in the 50-59 age group. The phenomenon did not appear in males. The incidence of osteoporosis was 23. 19% in males and 28.7% in females after 40 years old, respectively. Conclusion This study provides an objective and effective evidence for prevention, diagnosis, and treatment of osteoporosis, by exploring the BMD pattern and osteoporosis incidence in Chinese population in Beijing urban region.
