目的了解2007-2008年石河子市6个月内纯母乳喂养率,探讨发放母乳喂养教育材料对6个月内婴儿纯母乳喂养的影响。方法采用队列研究对2007-2008年石河子市人民医院、石河子大学医学院第一附属医院、石河子市妇幼保健院分娩的347例产妇进行单盲随机问卷调查,在奇数月份分娩的产妇发放母乳喂养教育材料,作为干预组;偶数月份分娩的产妇不发放教育材料,作为对照组。出院后分别在婴儿0.5、1.5、2.5、3.5、4.5、6.0个月时,电话随访其喂养和健康状况。应用生存分析计算纯母乳喂养率,Kaplan-Meier过程比较纯母乳喂养持续时间。结果1.干预组各月龄纯母乳喂养率显著高于对照组(P<0.05)。2.干预组纯母乳喂养持续时间显著长于对照组(P<0.05)。结论发放母乳喂养教育材料可提高纯母乳喂养率和延长纯母乳喂养持续时间。
Objective To understand the 6-month exclusive breastfeeding rate in Shihezi City during 2007-2008 and to explore the effect of delivering breastfeeding educational material on exclusively breastfeeding infants within 6 months. Methods A cohort study was conducted to investigate the frequency of breastfeeding among 347 mothers in Shihezi City People’s Hospital, the First Affiliated Hospital of Shihezi University and the Shihezi Maternal and Child Health Hospital in 2007-2008.

After discharge, at 0.5, 1.5, 2.5, 3.5, 4.5 and 6.0 months, respectively, the infants were followed up for feeding and health status by phone. The exclusive breastfeeding rates were calculated using survival analysis and the Kaplan-Meier process compared to exclusive breastfeeding durations. Results 1. The exclusive breastfeeding rate of the intervention group was significantly higher than that of the control group (P <0.05). The intervention group only breastfeeding duration was significantly longer than the control group (P <0.05).
