新生儿出生体重与出生方式的关系

目的:探讨重庆市主城区9年新生儿出生体重变化趋势及其与出生方式的关系。方法:对2002～2010年重庆市主城区筛查的104 234名新生儿的出生体重及出生方式进行回顾性分析。比较新生儿出生体重变化趋势及其与出生方式的关系。结果:9年间重庆市主城区新生儿出生体重有增加趋势;剖宫产率处于较高水平;不同出生体重新生儿出生方式存在差异,出生体重大于4 000 g和出生体重3 500～4 000 g的新生儿组剖宫产率高于其他组。结论:胎儿体重的增长,增加了剖宫产率。重视孕妇孕期体重管理,控制新生儿出生体重,可作为降低剖宫产率的措施之一。

Relationship between birth weight of neonates and delivery modes

Objective:To explore the relationship between change trend of neonatal birth weight and delivery modes from 2002 to 2010.Methods:The birth weights and delivery modes of 104 234 neonates from the main urban area of Chongqing city from 2002 to 2010 were analyzed retrospectively.The change trend of neonatal birth weight and its relationship with delivery modes were compared.Results:From 2002 to 2010,the average birth weight of the neonates in main urban area of Chongqing city showed an increasing trend;the rate of cesarean section was high;there was significant difference in the delivery modes among the neonates with different birth weights,the rates of cesarean section in birth weight>4 000 g group and 3 500-4 000 g group were significantly higher than those in the other groups.Conclusion:The increase of fetal weight increases the rate of cesarean section;paying more attention to maternal weight control during pregnancy and controlling neonatal birth weight can be used as measures to reduce the rate of cesarean section.
