Results The peak values of broadband ultrasound attenuation(BUA)and peak values of sound of speed (SOS) was in 40～49 years for female and in 30～39 years for male;the peak values of sound of speed(SOS)was in 20～29.

结果女性峰值骨量跟骨振幅超声衰减(BUA)出现在40~49岁,超声声速(SOS)出现在20~29岁,而男性峰值骨量跟骨振幅超声衰减(BUA)、超声声速(SOS)出现在30~39岁,各年龄组男性的BUA、SOS均高于女性:BUA、SOS在绝经后妇女明显低于绝经前妇女,正常体重和超重组跟骨超声参数均高于低体重组。
