Fetal weight is one of the important indicators for judging whether fetal growth and development are normal. Fetal weight exceeding the normal range may lead to poor delivery outcomes.
We aimed to establish a personalized fetal growth curve in order to effectively monitor fetal growth during pregnancy. Fetal weight can be monitored while fetal growth and development are assessed.
This study retrospectively analyzed the birth weight and ultrasound database of 3,093 newborns delivered at normal term. The personalized fetal growth curve model was generated based on the birth weight formula established by Gardosi combined with the proportional weight equation.
(1) The average birth weight of the single fetus at normal term was 3,457g. (2) According to the regression results of the proportion of fetal weight in full-term pregnancy and gestational week, the proportional weight equation is Weight% = 500.9 - 51.60GA + 1.727GA2- 0.01718GA3 (GA is gestational week), R2 is 98%, P< 0.001.
In this study, the normal birth weight of newborns and normal range of fetal weight can be estimated by using the personalized fetal growth curve model.
胎儿体重是判断胎儿生长发育是否正常的重要指标之一。胎儿体重超出正常范围可能导致不良分娩结局。
建立个性化胎儿生长曲线，以便在妊娠期间有效监测胎儿生长情况。同时可以监测胎儿生长发育情况，监测胎儿体重。
本研究回顾性分析了 3093 例足月分娩新生儿的出生体重和超声数据库。基于 Gardosi 建立的出生体重公式，结合比例体重方程，生成个性化胎儿生长曲线模型。
（1）足月单胎胎儿的平均出生体重为 3457g。（2）根据胎儿体重占足月妊娠和孕周比例的回归结果，比例体重方程为 Weight%=500.9-51.60GA+1.727GA2-0.01718GA3（GA 为孕周），R2 为 98%，P<0.001。
本研究通过使用个性化胎儿生长曲线模型，可以估计新生儿的正常出生体重和胎儿体重的正常范围。
