摘　　要：目的　评价藏族女性跟骨超声参数变化规律以及骨质疏松发病率。方法　用定量超声骨密度仪测定了2 0 8例正常藏族女性右跟骨宽带超声衰减、超声声速和骨硬度指数。结果　藏族女性跟骨峰值骨量出现在 30～ 39岁。 4 0岁以后各组与峰值组比较有显著性差异 ,各组间比较差异显著。 4 0岁以后 3组骨质疏松发病率分别为 11.76 %、2 2 .5 8%和 34.0 9%。反映增龄性改变BUA最敏感 ;骨质疏松检出率BUA与STI相同 ,均大于SOS。结论　跟骨定量超声三种参数均可应用于骨质疏松症检测 。Objective To study changes of the parameters of quantitative ultrasonometry (QUS) and incidence of osteoporosis in normal Tibetan women. Methods? WTBZ]Ultrasound parameters were measured in right calcaneus of 208 subjects(age 12-74 years), including broadband ultrasound attenuation (BUA, dB/MHz) ,speed of sound(SOS, m/s) and stiffness index(STI). Ultrasound parameters were measured in right calcaneus of 208 subjects(age 12-74 years), including broadband ultrasound attenuation (BUA, dB/MHz) ,speed of sound(SOS, m/s) and stiffness index(STI). Results Mean bone peak was observed in those of 30-39 years old. The ultrasound parameters reduced markedly in the 40～, 50～and over60 age groups; the difference were significant between any one group of them and the 30～ age group, and between any two groups of them( P <0.05). The incidence of osteoporosis for the 40～, 50～ and 60～ age group was 11.76%, 22.58% and 34.09% respectively. BUA was the most sensitive parameter in accessing the changes in various age group; and BUA and STI were similar in detecting the incidences of OP, both higher than those by SOS. Conclusions BUA, SOS and STI can be used in detecting bone loss and osteoporosis; BUA is the most sensitive parameter.
