Body Composition Studies in Premenopausal Healthy Women
Dual photon absorptiometry (DPA) is a potentially exciting tool in studies of body composition. It allows direct measurement of total bone mass and lean body mass as well as fat mass that can then be calculated from all pixels of a total body scan that do not contain bone. Thus, a semi-direct measurement of fat mass is obtained. Importantly, DPA or its modern x-ray equivalent can be applied to a much broader population including the aged and other individuals who have disorders that would preclude their participation in underwater weighing. We have evaluated the technique in a relatively homogeneous population of premenopausal women and here report the preliminary results and problems perceived thus far.
