昆山地区336例青年人胫骨定量超声骨量研究

Quantitative ultrasound assessment of tibia in 336 young subjects in Kunshan District

目的 为昆山地区胫骨定量超声骨量峰值的建立提供标准化方法并积累数据。 方法以社区 2 4～ 43岁青年健康志愿者 3 3 6例为研究对象 ,用QUA测定胫骨定量超声骨量值。结果 昆山地区男、女性人群的定量超声骨量峰值均出现在 3 2～ 3 5岁年龄段 ,其值分别为 (40 42 6± 76 6)m/s(男性 )和 (40 3 4 8± 70 2 )m/s(女性 )。 40岁以前 ,SOS值无明显性别差异 ,40岁以后 ,女性SOS值明显低于男性。结论 胫骨定量超声骨量峰值无明显性别差异 。

Objective To establish the standard method for the peak bone mass of tibia quantitative ultrasound in Kunshan District Methods A total of 336 healthy young people aged 24-43 years were selected randomly to undergo bone mass measurement by QUS Results The peak bone mass of tibia quantiative ultrasound in Kunshan District was seen in 32-35 year old group,which was the same for both male (4042 6±76 6 m/s) and females (4034 8±70 2 m/s) And in females, the SOS value declined at over 40 years of age,while it remained unchanged in males So a difference existed between males and females ( P<0 01) over 40 years of age Conclusion No significant difference in peak bone mass of tibia quantitative ultrasound is found in males and females , and these measuring values can serve as the baseline for the diagnosis of osteoporosis in clinical application and epildemiological studies
