The purpose of this study was to assess whether providing a breastfeeding support team results in higher breastfeeding rates at 6, 12, and 24 weeks postpartum among urban low-income mothers.
A randomized controlled trial with mother-infant dyads recruited from 2 urban hospitals.
Breastfeeding mothers of full-term infants who were eligible for Special Supplemental Nutrition Program for Women, Infants, and Children (n=328) were randomized to intervention (n=168) or usual-care group (n=160).
The 24-week intervention included hospital visits by a breastfeeding support team, home visits, telephone support, and 24-hour pager access. The usual-care group received standard care.
Breastfeeding status was assessed by self-report at 6, 12, and 24 weeks postpartum.
There were no differences in the sociodemographic characteristics between the groups: 87% were African American, 80% single, and 51% primiparous. Compared with the usual-care group, more women reported breastfeeding in the intervention at 6 weeks postpartum, 66.7% vs 56.9% (odds ratio, 1.71; 95% confidence interval, 1.07-2.76). The difference in rates at 12 weeks postpartum, 49.4% vs 40.6%, and 24 weeks postpartum, 29.2% vs 28.1%, were not statistically significant.
The intervention group was more likely to be breastfeeding at 6 weeks postpartum compared with the usual-care group, a time that coincided with the most intensive part of the intervention.
本研究旨在评估为城市低收入母亲提供母乳喂养支持团队是否会提高产后 6、12 和 24 周的母乳喂养率。
这是一项在 2 家城市医院招募母婴对的随机对照试验。
符合妇女、婴儿和儿童特殊补充营养计划（WIC）资格的足月婴儿的母乳喂养母亲（n=328）被随机分配至干预组（n=168）或常规护理组（n=160）。
24 周的干预包括母乳喂养支持团队的医院访视、家访、电话支持和 24 小时传呼访问。常规护理组接受标准护理。
产后 6、12 和 24 周通过自我报告评估母乳喂养状况。
两组的社会人口学特征无差异：87%为非裔美国人，80%为单身，51%为初产妇。与常规护理组相比，更多的女性在产后 6 周报告母乳喂养，66.7%比 56.9%（优势比，1.71；95%置信区间，1.07-2.76）。产后 12 周和 24 周的母乳喂养率差异无统计学意义，分别为 49.4%比 40.6%和 29.2%比 28.1%。
与常规护理组相比，干预组在产后 6 周时更有可能进行母乳喂养，此时恰逢干预的最密集阶段。
