摘要
目的探讨中老年男性在应用双能X线骨密度仪检测不同部位骨密度时应关注检测的部位。方法选取2012年9月至2014年12月在我院行双能骨密度检测的中老年男性,比较腰椎、髋部、前臂桡骨下1/3的骨密度(BMD)和T值。结果中老年男性腰椎、髋部、前臂桡骨下1/3三个部位的BMD和T值比较,P<0.001差异有统计学意义。随着年龄逐渐增大,腰椎BMD和T值下降不明显,髋部、前臂BMD和T值60岁以后才逐渐降低,前臂T值下降幅度明显大于腰椎和髋部。随着年龄的增加,髋部及前臂骨质疏松检出率也逐渐增加,但腰椎骨质疏松检出率随年增加反而下降。结论应用双能X线骨密度仪检测腰椎、髋部、前臂3个部位,经比较发现老年男性髋部和前臂BMD和T值明显低于腰椎,而且腰椎BMD和T值相对平稳,提示对老年男性骨质疏松诊断应同时检测髋部和前臂骨密度,以免出现骨质疏松的漏诊。
Objective To investigate the sites of detection of bone mineral density（BMD） using dual-energy X-ray absorptiometry（DXA） in middle-aged men.Methods Middle-aged men receiving BMD test in our hospital from September 2012 to December 2014 were selected.BMD and T values of the lumbar spine,hip,and lower 1/3 of the forearm were compared.Results There was significant difference of BMD and T scores among the lumbar spine,hip,and the lower 1/3 of the forearm in middle-aged men（P 〈0.001）.As the age increased,BMD and T score of lumbar decreased gradually in the hip and the forearm after 60 years old,but not obviously in the lumbar spine.The decrease of T score in the forearm was more obvious than that in the lumbar spine and the hip.With the increase of age,the osteoporosis detection rate increased in the hip and forearm,but it decreased in the lumbar spine.Conclusion BMD and T score of the hip and forearm are significantly lower than those in the lumbar spine in aged men,when examined using DXA.BMD and T score of the lumbar spine are relatively steady,indicating that the BMD of the hip and forearm should be detected in aged men to avoid missed diagnosis of osteoporosis.
