To study newborns weight in singleton term births and the association between newborns birth weight and mode of delivery in 3 hospitals.
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.
(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).
(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 non-macrosomia. (3) Obstetricians should pay more attention to nutrition in gestation period to lessen the incidence of macrosomia and cesarean section.
研究三家医院单胎足月分娩新生儿体重及新生儿出生体重与分娩方式之间的关联。
本回顾性研究纳入了2005年1月至2009年12月在北京大学第一医院妇产科出生的13963名单胎足月活产新生儿（PU组）、滨州医学院附属医院的6519名新生儿（BMC组）以及首都医科大学燕京医学院密云医院的8725名新生儿（MYC组）。计算并比较新生儿体重及巨大儿发生率。将PU组和MYC组的新生儿分为巨大儿组2288名和非巨大儿组20400名，分析其分娩方式。
（1）PU组新生儿平均出生体重为（3386±414）g，BMC组为（3389±446）g，MYC组为（3445±449）g。MYC组新生儿出生体重显著高于PU组和BMC组（P = 0.000）。BMC组新生儿出生体重高于PU组，但未达到统计学差异（P = 0.638）。（2）PU组巨大儿发生率为7.935%（1108/13963），BMU组为9.802%（639/6519），MYU组为13.524%（1180/8725）。MYC组巨大儿发生率高于PU组和BMC组，BMC组巨大儿发生率高于PU组，差异有统计学意义（P = 0.000）。（3）巨大儿组剖宫产比例为75.306%（1723/2288），非巨大儿组为50.765%（10356/20400），差异有统计学意义（P = 0.000）。
（1）不同级别医院新生儿出生体重存在差异。（2）因巨大儿行剖宫产的风险高于非巨大儿。（3）产科医生应更加关注孕期营养，以降低巨大儿发生率和剖宫产率。
