Body composition measurement: A hierarchy of methods

The range of methods now available to estimate body composition is extensiv e, In most cases there is a relationship between cost, complexity and infor mation content. The consequence is that choices can still be made depending on the finances available and the needs of the health professional. This p aper reviews four methods ranging in availability and clinical detail. The alternatives are use of skinfolds, electrical impedance, underwater weighin g and dual energy X-ray absorptiometry. These should provide the practition er with viable options to consider in the assessment of body composition. A lthough no method has been designed specifically for children, reference is made throughout to studies on paediatric subjects of the major issues invo lved in these methods, which will assist paediatric endocrinologists in mak ing informed decisions.
