The purpose of this series is to prospectively validate the Chinese equations for predicting fetal weight developed in a previous study. A total of 640 Chinese fetuses were examined antenatally for biparietal diameter (BPD), abdominal circumference (AC) and femur length (FL) by real-time ultrasonography within two days of delivery. ⋯ Our results demonstrate that the Chinese equations developed by Hsieh et al are a better fit for Chinese fetuses than the foreign equations are. Also, the two Chinese equations predict fetal weight well between 2,000 g and 4,000 g, but further modification is needed in cases where the BW is less than 2,000 g or greater than 4,000 g.
