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
