对儿童或成人肥胖症评估的回顾通常从肥胖症的字典定义开始，即“过度肥胖”。这就需要考虑肥胖的评估和确定正常范围，超过该范围，身体脂肪的量就过量了。身体脂肪的测量在所有年龄段都是间接的，并且基于最好的近似假设，并且通常是错误的。此外，由于误差与所有测量程序相关，因此获得的数值不如它们可能出现的准确。在前面的句子中暗示的局限性是标记为儿童在两个方面的评估肥胖症和正常范围的确定，本次审查将被限制到全身组成和方法的基础上：（一）全身水分，（二）全身钾，（三）皮褶厚度，（四）电导率，（五）生物电阻抗，（六）光子吸收，（七）身体密度，（八）预测方程。重点将放在这些方法的假设的有效性，当他们被应用到正常的儿童，而不是他们的应用程序的实用性。
A review of the assessment of obesity, whether in children or adults, typically begins with the dictionary definition of obesity as “excessive fatness.” This leads to consideration of the assessment of fatness and of the determination of the normal range beyond which the amount of body fat is excessive. The measurement of body fat is indirect at all ages and based on assumptions that are approximate at best and commonly erroneous. Furthermore, because errors are associated with all measurement procedures, the numerical values obtained are less accurate than they might appear. The limitations implied in the preceding sentences are marked for children in regard to both the assessment of obesity and the determination of the normal range.This review will be restricted to total body composition and to methods based on the following:(i) total body water,(ii) total body potassium,(iii) skinfold thicknesses,(iv) electrical conductivity,(v) bioelectric impedance,(vi) photon absorptiometry,(vii) body density, and (viii) predictive equations. The emphasis will be on the validity of the assumptions underlying these methods when they are applied to normal children rather than the practicality of their application.
