Breastfeeding peer counseling support programs for low-income women have been implemented across the United States. Data from one such program were used to examine participant and program characteristics, of those enrolled prenatally (n = 2168) or postnatally (n = 2899), and to determine how these characteristics affected breastfeeding outcomes. Shorter breastfeeding duration was significantly predicted by introduction of formula on day 1 postpartum in participants enrolled prenatally (-37.9 days [95% CI: -57.9 to -17.9]) as well as postnatally (-49.1 days [95% CI: -63.4 to -34.8]). In both groups, increasing maternal age and previous breastfeeding experience were associated with significantly longer breastfeeding duration. Breastfeeding duration may be improved in programs by targeting younger mothers, those without breastfeeding experience, and focusing on delaying the introduction of formula.
美国各地都为低收入女性实施了母乳喂养同伴咨询支持项目。从其中一个这样的项目中获取的数据，用于研究产前（n = 2168）或产后（n = 2899）登记参与者的特征以及项目特点，并确定这些特征如何影响母乳喂养结果。对于产前登记的参与者，产后第1天开始使用配方奶可显著预测母乳喂养持续时间缩短（-37.9天[95%可信区间：-57.9至-17.9]），产后登记的参与者也是如此（-49.1天[95%可信区间：-63.4至-34.8]）。在两组中，母亲年龄增加和既往母乳喂养经历与显著更长的母乳喂养持续时间相关。通过针对年轻母亲、没有母乳喂养经验的母亲，并着重推迟引入配方奶，项目中的母乳喂养持续时间可能会得到改善。
