中国产妇分娩方式与全母乳喂养率关联性的Meta分析

目的:系统评价我国产妇不同的分娩方式与婴儿4个月内全母乳喂养率的关联性。方法:检索CNKI、万方、维普数据库2000～2012年间公开发表的关于产妇分娩方式与婴儿喂养方式间关联性的研究。选择Revman 5.0软件进行统计分析,各研究间存在统计学异质性(P<0.000 01),故采用随机效应模型合并效应值OR及其95%CI。结果:检索到265篇文献,最终纳入11篇文献。Meta分析结果显示,产妇经阴道分娩后与剖宫产术分娩后的全母乳喂养率合并效应值OR及其95%CI为:OR=2.15,95%CI:1.74～2.65,P<0.000 01。根据观察时间进行亚组分析,亚组产后7天内,产后的第14天,产后28天内,产后的第42天,产后4个月内,差异无统计学意义(P=0.73)。结论:产妇不同的分娩方式与婴儿全母乳喂养率之间存在关联性,经阴道分娩的产妇产后4个月内的全母乳喂养率是经剖宫产术分娩产妇的2.15倍。产妇产后1周内所选择的喂养方式很大程度上影响了婴儿4个月内的喂养方式。

Meta analysis on the correlation between delivery modes of parturient women and pure breastfeeding rate in China

Objective:To systematically evaluate the correlation between different delivery modes of parturient women and pure breastfeeding rate of infants within four months after birth in China. Methods:The literatures about the correlation between delivery modes of parturient women and feeding patterns of infants reported publically from CNKI,Wanfang Database,and Weipu Database from 2000 to 2012 were retrieved;Revman 5.0 software was used for statistical analysis,statistical heterogeneity existed among different studies(P<0.000 01),so OR and 95%CI were adopted. Results:A total of 265 literatures were retrieved,finally,11 literatures were included;the results of meta analysis showed that OR and 95%CI were 2.15 and 1.74-2.65,respectively(P<0.000 01).According to observation time,the cases were divided into different subgroups,there was no statistically significant difference among postpartum 7-day group,postpartum 14-day group,postpartum 28-day group,postpartum 42-day group,and postpartum 4-month group(P=0.73). Conclusion:There is correlation between different delivery modes of parturient women and pure breastfeeding rate of infants,the pure breastfeeding rate of infants within four months after birth born by parturient women receiving vaginal delivery was 2.15 times more than that of infants within four months after birth born by parturient women receiving cesarean section;the feeding patterns within one week after birth has great impact on feeding patterns of infants within four weeks after birth.
