Abstract：Objective To analyze the relationship between body mass change during pregnancy and the occurrence rate of huge infant, delivery mode and neonatal disease.Methods A retrospective analysis of 140 cases of hospitalized preg-nant women from January 2011 to December 2014 were performed.Among them, quality delivery of newborns is equal to or more than 4 000 g’ s pregnant women of 68 cases were fetal macrosomia group, neonatal birth weight from 2 500 to 4 000 g’ s pregnant women of 72 cases were normal fetus group, compared fetal macrosomia group and normal fetus group pregnant women’ s pre-pregnancy BMI and early pregnancy, pregnancy and late pregnancy’ s body mass growth rate ( kg/week) , inves-tigated maternal body weight change and fetal macrosomia’s correlation.At the same time, compared differences in the rate of mode of delivery and neonatal diseases.Results Difference of pregnant women's age between the two groups showed no statis-tical significance ( P >0.05);fetal macrosomia group’s average pregnancy times, height, prenatal body mass, pre-pregnan-cy BMI and gestational weeks were higher than normal fetus group, the difference was statistically significant ( P <0.05). Fetal macrosomia group’ s second trimester and late pregnancy’ s body mass increased speed, prenatal body mass, prenatal ab-dominal circumference and BMI were higher than normal fetus group ( P <0.05);second trimester was the most fast increase of pregnancy body mass increased speed in both of the 2 groups, second trimester >third trimester >early pregnant, the differences were statistically significant ( P <0.05);fetal macrosomia group’s cesarean section rate and cephalopelvic, fetal distress, premature rupture of membranes, postpartum hemorrhage and neonatal asphyxia were significantly higher than that in normal fetuses ( P <0.05) .Conclusion There is a close relationship between the body weight and the occurrence of the fe-tal macrosomia.
