This study compared the use of fetal growth curves with the Rossavik mathematical model in predicting third trimester fetal growth in 27 Hispanic patients. The parameters tested were BPD, HC, AC, and FL. The growth curve method of predicting third trimester fetal growth was significantly more accurate than the mathematical model for three of the four fetal parameters tested: BPD, HC, and FL. We conclude that the mathematical model method offered no advantage over the more commonly used growth curve method for predicting third trimester fetal growth. In addition, growth curves do not require complex calculations and are conceptually simpler and easier to use.
本研究比较了胎儿生长曲线与罗萨维克数学模型在预测27名西班牙裔患者孕晚期胎儿生长情况时的应用。所测试的参数为双顶径（BPD）、头围（HC）、腹围（AC）和股骨长度（FL）。对于所测试的四个胎儿参数中的三个：双顶径、头围和股骨长度，预测孕晚期胎儿生长的生长曲线方法比数学模型显著更准确。我们得出结论，在预测孕晚期胎儿生长方面，数学模型方法相比更常用的生长曲线方法并无优势。此外，生长曲线不需要复杂的计算，在概念上更简单且更易于使用。
