To evaluate the effectiveness of a breastfeeding promotion program in the Women, Infant and Children (WIC) Supplemental Nutrition Program participants.
This randomized clinical trial included 52 women in the intervention group who received one-to-one pre- and postnatal breastfeeding education and support from a lactation consultant. Women (n = 52) randomized to controls received standard breastfeeding services. Data regarding their infants' feeding (classified as exclusive, partial, and bottle) during the first 7 days, 1, 2, and 3 months of age were compared. Additionally, the mothers were surveyed to assess their knowledge, attitude, and beliefs regarding breastfeeding.
Among the 104 enrolled women, 91 (87.5%) were Hispanic. Almost all the pregnant women had planned to breastfeed their infants. Although the majority of women reported breastfeeding their infants, 45.6% in the intervention group and 28.9% of controls practiced exclusive breastfeeding during the first 7 days. By 3 months, the rate of exclusive breastfeeding in the intervention and control groups had dropped to 13.9% and 10.5%, respectively. Parity, mode of delivery, previous experience with breastfeeding, rooming in, and return to work did not significantly affect the exclusive breastfeeding rate. Maternal knowledge, attitude, and beliefs regarding breastfeeding were comparable between the study groups at the baseline stage as well as 3 months postpartum.
Participation in the proposed breastfeeding promotion program by the low-income mothers was associated with an insignificant increase in the exclusive breastfeeding rate during the first 3 postpartum months.
评估妇女、婴儿和儿童（WIC）补充营养计划参与者中母乳喂养促进项目的有效性。
这项随机临床试验纳入了52名干预组女性，她们在产前和产后接受了来自泌乳顾问的一对一母乳喂养教育和支持。随机分配到对照组的52名女性接受标准母乳喂养服务。比较了她们的婴儿在出生后第7天、1个月、2个月和3个月时的喂养情况（分为纯母乳喂养、部分母乳喂养和奶瓶喂养）。此外，对母亲进行了调查，以评估她们对母乳喂养的知识、态度和信念。
在104名登记入组的女性中，91名（87.5%）为西班牙裔。几乎所有孕妇都计划母乳喂养婴儿。尽管大多数女性报告对婴儿进行母乳喂养，但干预组在出生后第7天纯母乳喂养的比例为45.6%，对照组为28.9%。到3个月时，干预组和对照组的纯母乳喂养率分别降至13.9%和10.5%。产次、分娩方式、既往母乳喂养经历、母婴同室和重返工作岗位对纯母乳喂养率没有显著影响。在基线阶段以及产后3个月时，两组母亲对母乳喂养的知识、态度和信念相当。
低收入母亲参与拟议的母乳喂养促进项目与产后前3个月纯母乳喂养率的微小增加相关。
