Measurement of body composition is important in the assessment of nutritional status in cancer patients. The purpose of this study was to validate the bioelectrical impedance (BI) method for body composition estimation in 33 elderly cancer patients (mean age 66 +/- 9 years) using the deuterium dilution technique (2H2O) as the reference method. Height2/Resistance (H2/R) correlated significantly with total body water (TBW) computed from 2H2O (r = 0.89, P less than 0.001; s.e.e. = 2.4 l). The prediction equation for TBW improved significantly (P less than 0.001) by addition of H2/R to the predictor variables weight, height, age and sex. We conclude that BI is a useful measure for the assessment of body composition in cancer patients.
身体成分的测量对于评估癌症患者的营养状况很重要。本研究的目的是使用氘稀释技术（2H2O）作为参考方法，验证生物电阻抗（BI）法在33例老年癌症患者（平均年龄66±9岁）中估算身体成分的有效性。身高的平方除以电阻（H2/R）与通过2H2O计算的总体水（TBW）显著相关（r = 0.89，P < 0.001；标准误 = 2.4升）。通过在预测变量体重、身高、年龄和性别中加入H2/R，TBW的预测方程有显著改善（P < 0.001）。我们得出结论，BI是评估癌症患者身体成分的一种有用方法。
