Abstract:
Objective To study newborns weight in singleton term births and the associationbetween newborns birth weight and mode of delivery in 3 hospitals.Methods From Jan.2005 to Dec.2009,13 963 singleton term live neonates born in the Department of Obstetrics and Gynecology of Peking University First Hospital(PU group),6519 neonates in Affiliated Hospital of Binzhou Medical College (BMC group,)and 8725 neonates in Miyun Hospital Affiliated to Capital Medical University,Yanjing Medical College(MYC group)were enrolled in this retrospective study.The newborns weight and the rate of macrosomia was calculated and compared.Those newborns from PU group and MYC group were divided into 2288 neonates at macrosomia group and 20 400 neonates at non-macrosomia group,their mode of deliveries were analyzed.Results(1)The mean neonatal birth weight were(3386 ± 414)g at PU group,(3389 ± 446)g at BMC group and(3445 ± 449)g at MYC group.Neonates born weight in MYC was significantly higher than those from in PU group and BMC group(P =0.000).Neonates born weight in BMC showed higher than those in PU group,which did.not reached statistical difference(P =0.638).(2)The incidence of macrosomia were 7.935％(1108/13 963)in PU group,9.802％(639/6519)in BMU group and 13.524％(1180/8725)in MYU group.The incidence of macrosomia in MYC group was higher than those in PU and BMC group,the incidence of macrosomia in BMC group was higher than that in PU group,which reached statistically difference(P =0.000).(3)The proportion of cesarean delivery were 75.306％(1723/ 2288)at macrosomia group,50.765％(10 356/20 400)at non-macrosomia group,which showed statistical difference(P =0.000).Conclusions(1)The difference of newborns birth weight existed in different administrative level hospital.(2)The risk of cesarean delivery due to macrosomia is higher than that of nonmacrosomia.(3)Obstetricians should pay more attention to nutrition in gestation period to lessen the incidence of macrosomia and cesarean section.
