Should fetal weight growth curves be population specific?
GROUND AND OBJECTIVES: The use of ultrasound to estimate fetal weight has become very common. Several studies have examined which fetal parameters predict best fetal weight, and based on those parameters fetal growth curves have been established. It is possible however, that fetal growth patterns differ across population groups, and therefore should be population specific. To establish fetal weight growth curve for the Israeli population and to compare it to the one currently used, suggested by Hadlock et al. METHODS: A cross-sectional study of singleton pregnancies was conducted. For each fetus the estimated weight was calculated using sonographic measurements of bi-parietal diameter, femur length, abdominal circumference, and head circumference. A regression analysis was used to evaluate the relationship between weight and fetal age. RESULTS: A growth curve was established based on measurements of 857 fetuses. There was a gradual increase in fetal weight from 99 grams at 14 weeks to
