Body composition measurements are useful in assessing the effectiveness of nutritional interventions and monitoring the changes associated with growth and disease conditions. The only fully accurate measurement of body composition is cadaver whole body dissection analysis previously undertaken as part of the brussels cadaver analysis study 5. Body composition can be assessed in a number of different ways with methods ranging in technicality cost and accuracy. Body composition is known to be associated with several diseases such as cardiovascular disease diabetes cancers osteoporosis and osteoarthritis.

A review and recommendations for best practice. A three compartment 3c model of body composition assessment which combines measures of body density and tbw from 2 h dilution d 2 o rather than an assumed constant affords greater validity and is shown to be closer to the reference method in body composition assessment 1 6. Measurement and definitions in body composition the application of limits in allowable body composition in the military depends on several assumptions. The first and primary assumption is that a single arbitrary point on the continuum of body fatness represents a reversible abnormality. The most accurate estimation of body composition is derived from body density by means of the equation of fractional densities which states that the overall density of a mixture containing more than one substance each with a different density can be calculated if the proportion and density of each component substance is known.
