背景双能X线、CT有射线、验血有创伤和感染的概率,不适合骨质疏松症的普查和跟踪随访。而超声骨密度仪具有无放射性、无创伤性、重复性好的优点,它根据受检者的年龄、性别和体质量等许多项参数得出的结果,数据相对可靠。目的了解老年知识分子的骨质疏松症的情况,为今后此病的预防、诊断和治疗提供有效依据。设计以诊断为依据的病例对照研究。地点、对象和方法对上海市南市区离退休教师作跟骨骨密度检查。男150例,体质量(67±10)kg;女663例,体质量(59±9)kg。调查退休教师的年龄、性别、体质量、身高和多种疾病(糖尿病、结核、高血压、骨质增生和骨折等)与超声振幅衰减值(broadbandultrasoundattenuation,BUA)之间的关系。主要观察指标男女骨质疏松症患者跟骨BUA值。结果男性、女性组平均BUA值分别为63.9,58.9dB/MHz,声速分别为1485.2,1504.1m/s。体质量与BUA、声速呈显著正相关(R=0.0466,0.1773,P<0.05)。男女性喝牛奶与不喝牛奶组BUA值比较,差异有显著性意义(χ2=4.0124,5.9495,P<0.05)。男性得与未得肺结核患者BUA值差异有显著性意义(χ2=6.3882,P<0.05)。体质量大于或等于65kg者BUA值小于正常参考值的人数明显减少,在60岁以上随着年龄增长与骨量的丢失之间没有显著关系。结论受检者的年龄、性别、体?
Background Dual-energy X-ray, CT with ray, blood test trauma and infection probability, not suitable for census and follow-up of osteoporosis. The ultrasonic bone densitometer with no radioactive, non-invasive, good repeatability, which according to the subjects of age, gender and body mass and many other parameters of the results obtained, the data is relatively reliable. Objective To understand the situation of osteoporosis in the aged intellectuals and provide an effective basis for the prevention, diagnosis and treatment of this disease in the future. Case-control studies based on diagnosis were designed. Location, Subjects and Methods The calcaneal bone mineral density test was performed on retired teachers in Nanshi District, Shanghai. There were 150 males with body weight (67 ± 10) kg and 663 females with body weight (59 ± 9) kg. The relationship between age, sex, body mass, height, and various diseases (diabetes, tuberculosis, hypertension, osteoproliferation, fractures, etc.) and broadband ultrasound findings (BUA) of retired teachers was investigated. MAIN OUTCOME MEASURES BUA value of calcaneus in men and women with osteoporosis. Results The average BUA of males and females were 63.9 and 58.9 dB / MHz respectively, and the sound velocities were 1485.2 and 1504.1 m / s respectively. Body mass and BUA, sound velocity was significantly correlated (R = 0.0466,0.1773, P <0.05). There was significant difference in BUA between male and female drinking milk and no drinking milk group (χ2 = 4.0124,5.9495, P <0.05). There was a significant difference in BUA between male and non-tuberculosis patients (χ2 = 6.3882, P <0.05). Patients with a body mass greater than or equal to 65 kg had significantly lower BUA values than the normal reference values and no significant association with bone loss over age 60 with age. Conclusion Subject’s age, gender, body?
