摘要
目的了解本地区成年人群腰椎、股骨近端各部位骨密度（Bone mineral density BMD）的变化规律及骨质疏松患病率情况,为骨质疏松的诊断及预防提供科学依据。方法采用美国Lunar公司的Prodigy系列双能X线骨密度仪测量1123例成年人群腰椎、非优势（左）股骨近端各部位（股骨颈、大粗隆及Wards三角）BMD值,按5岁1个年龄组分11组对数据进行统计分析。结果贵阳地区成年女性腰椎及股骨近端骨峰含量出现在25-29岁组,成年男性腰椎及股骨近端骨峰含量出现在30-35岁组,且腰椎及股骨近端各部位BMD值均随年龄增长而下降,在50-59岁后骨量呈快速丢失现象。结论骨质疏松患病率与增龄有关,女性50岁以后、男性60岁以后患病几率增大,应及早预防。
Objective To study the bone mineral density （BMD） of adults＇ lumbar vertebrae and proximal femur change and the prevalence of osteoporosis in Guiyang area and to provide scientific basis for diagnosis and prevention of osteoporosis. Methods Bone mineral density of the lumbar spine and proximal femur in 1123 female adults was measured with lunar Prodigy dual-energy X-ray absorptiometer made in USA. All data were analyzed for eleven age groups of five each. Results and Conclusion The peak bone mass of lumbar vertebrae and proximal femur occurred in the age group 25 - 29 in females and the age group 30 - 35 in males. All BMD values decreases as age increases. The prevalence of osteoporosis increases with age, especially after 50 years old in women and 60 years old in men. Earlier prevention is important for osteoporosis.
