摘　　要：目的经体重指数标准化,分不同年龄段进行比较,探讨定量骨超声测定的统一标准。方法采用UBIS5000型定量超声仪,对山西地区811例20～80岁正常成人(女468例,男343例)行跟骨定量超声参数测量。结果跟骨超声振幅衰减(BUA)和刚度(STI)的峰值女性在45～49岁犤BUA为(67.71±4.91)dB/MHz,STI为(86.3±14.5)%犦,BUA峰值男性在50～54岁犤(71.41±7.69)dB/MHz犦。经体重指数校正后,不论男性或女性BUA、STI及超声波传导速度(SOS)峰值均在20～24岁。结论跟骨BUA、SOS和STI随年龄增长而变化,消除体重指数影响后差异仍明显,且随增龄逐年降低,男性变化趋势不如女性明显。Aim To measure the parameters of calcaneal quantitative ultrasound(QUS) in normal Shanxi subjects and standardize by body mass index(BMI),compared in different age section.Methods Calcaneal parameters were measured in 811 normal Shanxi subjects aged 20 to 80(468 women,343 men) by UBIS 5000 QUS.Results The peak values of broadband ultrasound attenuation(BUA) and stiffness(STI) of the calcaneus were both in 45- 49 years for women. The peak values of BUA was in 50- 54 years for men.Standardized by BMI, the peak values of BUA,STI and sound of speed(SOS) were both in 20- 24 years for women and men. Conclusion BUA,SOS and STI of the calcaneus may change with age.After eliminating the influence of body mass the change with age still existed obviously and the parameters may reduce with age growing gradually.<P>
