Technical Abstract: In vivo methods used to study human body composition continue to be developed, along with more advanced models that utilize the information obtained with these technologies. Some methods are well established, with a strong physiological basis for their measurement, while others are much more indirect. This review has been structured from the methodological point of view to help the reader understand what can be examined with each technique. The associations between the various in vivo methods (densitometry, dilution, bioelectrical impedance and conductance, whole- body counting, neutron activation, x-ray absorptiometry, computer tomography, and magnetic resonance imaging) and the 5-level multicompartment model of body composition are described, along with the limitations and advantages of each method. This review also provides an overview of the present status of this field of research in human biology, including examples of reference data for human body composition for infants, children, adolescents, and adults. |
