Individual total body water volumes for 458 adult males and 265 adult females obtained from dilution studies, together with their height, weight, and age have been selected from the literature. These values were used to derive total body water prediction equations for adults of any age. The equations that gave the best fit were for males: formula (see text) and for females: formula (see text). Numerous other linear regression equations to predict total body water from anthropometric measurements have been reported in the literature. Most apply only to restricted age groups. These, and the equations from the present study were tested on completely independent data. In all cases the equations from the present study gave the best overall results, though for women one equation designed for a specific age group, gave for that age group a marginally better fit.
从稀释研究中获取的458名成年男性和265名成年女性的个体总体水量，以及他们的身高、体重和年龄，均选自文献。这些数值被用于推导任何年龄成年人的总体水预测方程。拟合效果最佳的方程，对于男性为：公式（见正文），对于女性为：公式（见正文）。文献中还报道了许多其他根据人体测量数据预测总体水的线性回归方程。大多数方程仅适用于特定年龄组。这些方程以及本研究中的方程均在完全独立的数据上进行了测试。在所有情况下，本研究中的方程总体结果最佳，不过对于女性，一个为特定年龄组设计的方程，在该年龄组的拟合效果略好。
