Total-body skeletal muscle mass: estimation by dual-energy X-ray absorptiometry in children and adolescents

Background: Skeletal muscle (SM) is an important compartment but is difficult to quantify in children and adolescents. Objective: We investigated the potential of dual-energy X-ray absorptiometry (DXA) for measuring total-body SM in pediatric subjects. Design: A previously published adult DXA SM prediction formula was evaluated in children and adolescents aged 5–17 y (n = 99) who varied in pubertal maturation stage. SM estimated by whole-body...
