The graphs reflect the overall fetal growth variation in selected healthy low-risk pregnancies under favorable nutritional and social conditions in different parts of the world; and they encompass some significant differences in fetal growth formula Fetal weight (in gms.) Background: Accurate estimation of fetal weight is needed for growth monitoring and decision-making in obstetrics; the INTERGROWTH project developed an estimated fetal weight formula to construct new intrauterine growth standards. There was a statistically significant difference between the actual weight and the weight estimated by the Hadlock formula (p < 0.001). Hadlock estimated fetal weight formula was more accurate than INTERGROWTH formula for fetuses delivered between 2234 weeks of gestation. Our results support continued use of Hadlock formula in France and raise questions about the applicability of INTERGROWTH intrauterine growth standards. Ultrasound Obstet Gynecol 1994; 4: 34-48 . The estimated fetal weight from the measurements of HC, AC and FL is derived from the formula reported by: Hadlock FP, Harrist RB, Martinez-Poyer J. In utero analysis of fetal growth: a sonographic weight standard. A secondary aim was to identify the patients in which H2 formula is less reliable to use. The Pearson correlation coefficient for the Hadlock IV formula was strong at r = 0.935 (p < 0.001), with 319 (56.5%) of measurements falling within 10%, 408 (72.2%) within 15% and 455 (80.5%) within 20% of actual birth weight. None of the 3 sonographic formulas is ideal for estimating fetal weight in fetuses with AWDs. Ultrasound had to have been performed within 7 days of birth 1, 3 and include the national accepted standards of fetal biometry measurements as specified by the Australasian Society for Ultrasound in Medicine using the Hadlock formula for calculating estimated fetal weight. The Hadlock formula could therefore be improved by adjusting for fetal sex as previously suggested by others [8, 3033]. In our study, male and female fetuses differed in body composition with different indices for male and female fetuses. The aim of this study was to determine the accuracy of established ultrasound EFW formulae to identify small and large for gestational age fetuses when used after 35 weeks gestation. 241-55.
