摘要
目的 探讨新生儿出生体重 (NBW )的变化趋势及其与剖宫产率之间的关系。方法 回顾性分析上海市普陀区妇婴保健院 1989年至 1998年 10年间NBW的变化 ,及不同出生体重儿 (低体重儿、正常体重儿和巨大儿 )孕妇的分娩方式 ;并对初次产前检查≤ 2 0周至足月分娩的产妇 ,按NBW的不同分为 3组 ,分析孕妇孕期体质指数 (BMI)的增加与NBW之间的关系。结果 10年间NBW呈上升趋势 ,其中巨大儿的发生率明显增加 (P <0 .0 5 )、男婴多于女婴 (P <0 .0 0 5 )。随着NBW的增加 ,剖宫产率明显上升 (P <0 .0 0 5 )。巨大儿的孕妇其孕期BMI的增加与其它各组相比差异有显著性 (P <0 .0 0 1)。结论 NBW和孕妇孕期BMI的过度增加是导致巨大儿发生率和剖宫产率上升的重要因素。加强孕妇孕期的膳食指导将是控制NBW。
Objective To investigate the changing trend of neonatal birth weight (NBW) and relationship between NBW and cesarean section rate. Methods Retrospective analysis was made in the change of NBW and delivery modes of different NBW (low birth weight infant, normal birth weight infant, and macrosomia) in Shanghai Pu Tuo District Maternity and Infant Health Hospital from 1989 to 1998. Women, who received first prenatal check up ≤20 gestational weeks to mature delivery, were further divided into three groups based on the different NBW and relationship between BMI gain during pregnancy and NBW were comparatively analyzed. Results NBW presented with a rising trend over the past ten years. The incidence of macrosomia had been more increaseing ( P <0.05). As for the gender of macrosomic infants, male was predominant (P <0.005). The cesarean section rate was markedly increased ( P <0.005) with the raising of NBW raised. The BMI gain during pregnancy in the macrosomia group was higher than that of other two groups ( P <0.001). Conclusion The over increased NBW and maternal BMI gain during pregnancy have direct impact on increased macrosomia and higher cesarean section rate. To control NBW over increased and reduce cesarean section rate, diet consultation promoting scientific and appropriate nutrients intake of pregnant women should be improved.
