杭州桐庐地区1210例体检人群的骨密度情况分析

An evaluation of bone mineral density based on 1210 cases

目的对杭州桐庐地区体检人群进行骨密度测量分析,了解正常人群骨质疏松发生情况,为骨质疏松的防治提供科学依据。方法采用双能X线骨密度仪对桐庐地区2010年9月—2011年2月来本院体检的1 210例受试者进行骨密度测定,测量部位为左前臂(尺桡骨远端)。以骨峰值小于-1.0为骨量减少,骨峰值小于-2.5为骨质疏松,按性别年龄分组进行统计学分析。结果在1 210例体检者中,低骨量者共有289例(23.88%)、骨质疏松者共有548例(45.29%);女性骨质疏松398例(64.72%)明显高于男性骨质疏松150例(25.21%)(P<0.01);女性30岁以后、男性60岁以后患骨质疏松几率增大。结论正常人群中骨质疏松发生率较高,且与年龄呈正相关。

Objective The study was intended to evaluate the level of osteoporosis in the general public of Tonglu County and provide scientific knowledge for prevention and treatment of osteoporosis.Method 1210 people who came to the hospital for physical examination during September,2010 and February,2011 were selected as the subjects for our study.Dual-energy-X-ray absorptiometry was used bone density measurement.The left forearm（distal end of the radius） was chosen as the site for the measurement.Bone mass with its peak value less than-1.0 was considered case of osteopenia,and that less than-2.5 was considered case of osteoporosis.The subjects were divided into sub-groups according to the age bracket they came in.Findings Of the 1210 cases,289 cases suffered low bone mass;548 cases suffered osteoporosis.Among them,136 women appeared to experience low bone mass,while 398 female patients suffered osteoporosis.Incidence of osteoporosis was higher than in females than in males.64.72% of women tend to have the disease after turning 30 years of age,while 44.62% of men do so after turning 60 years of age.Conclusion The diseases in question were found to have considerably high incurrence in the general public of Tonglu area and to be positively correlated with an individual＇ age and gender.
