Abstract Normative data for qualitative ultrasound (QUS) measurements: speed of sound (SOS), broadband ultrasound attenuation (BUA), and stiffness were established in 118 healthy women aged 20–86 years and in 42 healthy men aged 22–76 years. The relations between age, weight, height, and QUS were studied. QUS measurements were negatively correlated with age in both sexes. In women, age was accepted as first factor (R2=0.39 for SOS, 0.35 for BUA, and 0.45 for stiffness, P〈0.001); weight was accepted as second factor for BUA (R2=0.44, P〈0.001). In men, age was the only significant parameter (R2=0.41 for SOS, 0.39 for BUA, 0.43 for stiffness, P〈0.001). QUS measurements of the right and the left feet were highly correlated unless unilateral foot pathology such as algodystrophy was present. Significant correlations were found between QUS of the calcaneus and dual X-ray absorptiometry (DXA) of the lumbar spine (R=0.67, P〈0.01 for SOS; R=0.57 P〈0.02 for BUA; R=0.65, P〈0.01 for stiffness).
