A simplified method of estimating fetal weight was developed and tested on 366 ultrasound examinations performed close to delivery. Constructed by linear regression on the sum of the biparietal diameter (BPD), mean abdominal diameter, and femur length against the logarithm of birth weight, the model was compared to the Shepard-Warsof model, which uses BPD and abdominal circumference to estimate fetal weight. Models using the same simplified approach to estimate fetal weight using BPD with mean abdominal diameter, and femur length with mean abdominal diameter, were also developed. Fetal weight estimate tables for these models involve only one variable, making them easier to use.
一种估算胎儿体重的简化方法被开发出来，并在接近分娩时进行的366次超声检查中进行了测试。该模型通过双顶径（BPD）、平均腹径和股骨长度之和与出生体重对数的线性回归构建而成，并与使用BPD和腹围来估算胎儿体重的谢泼德 - 沃索夫模型进行了比较。还开发了使用相同简化方法的模型，即分别使用BPD与平均腹径、股骨长度与平均腹径来估算胎儿体重。这些模型的胎儿体重估算表仅涉及一个变量，使用起来更加简便。
