A combination of body composition techniques was used to determine the body fat and the fat-free mass.
It has been validated in healthy subjects and various patient populations by isotope dilution and other body composition techniques [ 49].
However, before comparing body composition techniques, we must first recognize the important construct of categorizing body composition components into 5 distinct levels, ie, atomic level, molecular level, cellular level, tissue-systems level, and whole body level.
Nevertheless, BMI does not capture body composition changes that may occur with ageing and future studies with longitudinal body composition data are required.
Yet another factor is the accuracy of bioelectrical impedance technique when compared with reference body composition measurement techniques (hydrodensitometry, water dilution technique) or multicomponent models.
11– 14 Fortunately, a number of additional body composition measurement techniques are being utilized in obesity research that promise to improve our understanding of existing biological concepts and generate new hypotheses.
A combination of assessment techniques were used to monitor changes in body composition (that is, fat, water, protein and mineral), following intensive care unit (ICU) discharge, in a 38-year-old female recovering from extrapontine myelinolysis.
Body composition measurements showed that body fat mass was reduced in all treatments, with the greatest reduction from LA consumption.
Body composition measurements showed that an incredible 73% of the weight gained was due to an increase in body fat.
This review describes the following imaging techniques that may be used to assess body composition: dual-energy X-ray absorptiometry (DXA), computed tomography (CT) and magnetic resonance imaging (MRI).
