摘　　要：目的:调查健康体检中老年人的骨密度情况、骨质疏松患病率。方法:选取2018年1月~2019年12月在中日友好医院健康体检中心进行体检的>50岁的中老年人2164例。以双能X线法检测受试者腰椎及髋部的骨密度(BMD)。按性别及年龄分组,分析各组不同部位骨密度情况及骨质疏松的患病率,并比较不同部位骨量异常情况。结果:随年龄增长,男性和女性的髋部BMD均出现下降,而腰椎骨密度无明显变化趋势。随年龄增长,男性和女性骨质疏松症患病率均呈上升趋势,其中50~79岁各组女性患病率均明显高于同年龄组男性。50~54岁组的男性及女性的腰椎骨量异常患病率明显高于髋部;男性65~79岁各组、女性60岁以上各组髋部骨量异常患病率明显高于腰椎。结论:中老年人群,尤其是绝经后女性是骨质疏松症的高危人群;老年人群骨质疏松的筛查可以考虑选择髋部骨密度为主。推荐将髋部骨密度测定作为老年女性常规体检项目。Objective:To investigate the bone mineral density(BMD)and prevalence rate of osteoporosis in healthy middle-aged and elderly people.Methods:A total of 2164 middle-aged and elderly healthy people were examined in the Health Examination Center of China-Japan Friendship Hospital from Jan.2018 to Dec.2019.BMD of lumbar spines and hips was measured by dual-energy X-ray.Grouped by gender and age,the BMD and prevalence of osteoporosis in each group were analyzed and the prevalence rates of abnormal bone mass at different sites were compared.Results:With the increase of age,the BMD of both male and female hips decreased,but the BMD of lumbars showed no obvious trend.With the increase of age,the prevalence of osteoporosis increased in both men and women,and the prevalence of osteoporosis in women aged 50~79 years was significantly higher than that in men of the same age.The prevalence of lumbar bone abnormalities in males and females aged 50~54 years was significantly higher than that in the hips.The prevalence of hip bone abnormalities was significantly higher than that of lumbar in male group aged 65~79 years and female group aged over 60 years.Conclusion:Middle-aged and elderly people,especially postmenopausal women,are at high risk of osteoporosis.Hip bone density should be considered chiefly for osteoporosis screening in elderly people.Hip bone density measurement is recommended as a routine physical examination for elderly women.
