Several aspects of body composition, in particular the amount and distribution of body fat and the amount and composition of lean mass, are now understood to be important health outcomes in infants and children. Their measurement is increasingly considered in clinical practice; however, paediatricians are often unsure as to which techniques are appropriate and suitable for application in specific contexts. This article summarises the pros and cons of measurement technologies currently available for paediatric application. Simple techniques are adequate for many purposes, and simple regional data may often be of greater value than "whole body" values obtained by more sophisticated approaches.
身体成分的几个方面，特别是体脂肪的数量和分布以及瘦体重的数量和组成，现在被认为是婴幼儿重要的健康指标。在临床实践中，对它们的测量越来越受到重视；然而，儿科医生常常不确定哪些技术适用于特定情况。本文总结了目前可用于儿科的测量技术的优缺点。简单的技术足以满足许多目的，而且简单的局部数据往往比通过更复杂方法获得的“全身”数据更有价值。
