[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0035] The method for predicting the birth weight of a full-term (after 37 weeks) newborn at 21-23 weeks of pregnancy comprises the following steps,
[0036] Step S1: Establish a neonatal weight prediction model; the neonatal weight prediction model is EFW=5016.51-205.71×X1+16.30×X2+102.19×X3+86.64×X4, where EFW is the predicted weight of the newborn, and the unit is g; X1 is the exact gestational week at the time of ultrasound examination, and X2 is the body mass index of the pregnant woman at 21-23 weeks of pregnancy, in kg / m 2 ; X3 is the partial thigh volume of the fetus (50% of the volume of the middle thigh) during ultrasound examination, and the unit is cm 3 ; X4 is the abdominal circumference of the fetus d...
