Direct measurement of body surface area (Ab) was made on 20 male adult Nigerians of African descent by coating and planimetry. The results were compared with estimated Ab values obtained using six widely accepted height and weight prediction equations. The results show that existing formulas do not predict surface areas of our subjects accurately. Measured Ab values of our subjects were 6-22% greater than predicted values obtained from non-African nomograms. Using these results, we computed new variables for height and weight formulas that accurately predict the surface area of Africans. The closest fit to measured values is given by the equation Ab(m2) = 0.001315 x Height 1.2139 (cm) x weight 0.2620 (kg) +/- 0.04815 (SEE). The new variables are significantly different from those of existing equations. Our height variable is several times greater than the weight variable and reflects a greater importance of height than weight in determining the surface area of Africans than is the case with Caucasians.
通过涂层和平面测量法，对20名成年尼日利亚男性非洲裔受试者的体表面积（Ab）进行了直接测量。将测量结果与使用六个广泛认可的身高和体重预测方程得出的Ab估计值进行了比较。结果表明，现有公式无法准确预测我们受试者的体表面积。我们受试者的实测Ab值比从非非洲人列线图获得的预测值大6%-22%。利用这些结果，我们计算了身高和体重公式的新变量，这些变量能准确预测非洲人的体表面积。与测量值最接近的拟合公式为：Ab（m²）= 0.001315×身高1.2139（厘米）×体重0.2620（千克）±0.04815（标准误差估计值）。新变量与现有方程的变量显著不同。我们的身高变量比体重变量大几倍，这表明在决定非洲人的体表面积方面，身高比体重更重要，这一点与高加索人不同。
