Objective To investigatethe coincidence rate between the Hadlock ultrasound method and the clinical formula method(Yuan Dong method)in assessing estimated fetal weight(EFW).Methods A retrospective analysiswas performed for the clinical data of 1 715 pregnant women who were hospitalized and gave birth in Department of Obstetrics,Qingdao Women and Children's Hospital,from January to April 2020,and according to the body mass index(BMI)before pregnancy,they were divi-ded into underweight(BMI<18.5 kg/m2)group with 177 women,normal weight(18.5-23.9 kg/m2)group with 1 118 women,overweight(24.0-27.9 kg/m2)group with 317 women,and obese(≥28.0 kg/m2)group with 103 women.Fetal weight was esti-mated using the Hadlock ultrasound method and the Yuan Dong method,and the two methods were compared in terms of the difference between EFW and actual birthweight.Results The Hadlock method had a significantly higher accuracy than the Yuan Dong methodin estimating fetal weight in each group(x2=25.212-435.840,P<0.01).There was no significant difference in the accuracy of the Hadlock method in estimatingfetal weight betweenthe four groups(x2=1.392,P>0.05),while the accuracy of the Yuan Dong method in estimating fetal weight decreased significantly with the increase in BMI(x2=59.34,P<0.01).Conclusion The Hadlock method has a significantly higher accuracy than the Yuan Dong method in estimating fetal weight and is not affected by the BMI of pregnant women before pregnancy.
