title: Body composition in humans: advances in the development of multicompartment chemical models.
abstract: Until recently it was practical to divide body weight into only two or three chemical compartments in living subjects due to an inability to quantify directly total body mineral, protein, and fat in vivo. The six-compartment chemical model is now the cornerstone of research in human body composition. Advanced technologies, including neutron activation analysis systems and dual photon absorptiometry, now enable investigators to extend body composition estimates and to construct near-complete chemical models in vivo. These new or refined approaches will advance our knowledge of human body composition and will also improve our accuracy in calibrating simpler epidemiologic and bedside body-composition techniques.
