Influence of Soft Tissue (Fat and Fat-Free Mass) on Ultrasound Bone Velocity

Abstract

These results, to our knowledge, are the first to be obtained by in vivo evaluation of UBV in relation to body fat and fat-free mass. Body fat, but not fat-free mass, was the main factor affecting UBV. This confirms the deficiency of UBV measurements, considering that obesity is a protective factor for bone mass.
