描述了一种用于估计人体成分的新方法，该方法需要测量全身电导率。该方法基于瘦肉组织的导电性远大于脂肪的导电性的原理。对19名肥胖程度差异很大的成年人进行的比较研究表明，受试者的总电导率与他们的总身体水分（r = 0.87）和总身体钾（r = 0.86）之间具有良好的相关性。这种非侵入性的方法，这是安全，简单，快速，方便，应证明是有用的个人和人群的营养评估。
A new method for the estimation of body composition in human subjects is described which entails the measurement of total body electrical conductivity. The method is based on the principle that the electrical conductivity of lean tissue is far greater than that of fat. Comparative studies in 19 adults of widely varying fatness have demonstrated excellent correlations between the total electrical conductivity of the subjects and both their total body water (r = 0.87) and total body potassium (r = 0.86). This noninvasive method, which is safe, simple, rapid, and convenient, should prove useful in the nutritional assessment of individuals and populations.
