A randomized controlled trial study design was used to investigate the effectiveness of a Healthy Families America model prenatal intervention for increasing breastfeeding rates among Latina immigrants residing in an impoverished New York City community. Exposure to the intervention did not affect mother report of any breastfeeding (ABF) during the first week postpartum, but it did affect mother report of exclusive breastfeeding (EBF). Thirty-two percent (44/137) of mothers exposed to the intervention reported EBF during the first week postpartum compared to 20% (20/101) of mothers not exposed to the intervention (odds ratio 1.92; 95% confidence interval 1.05-3.52). This positive effect of the intervention on EBF remained statistically significant after controlling for the negative effect of household income on EBF (adjusted odds ratio, 1.89; 95% confidence interval, 1.02-3.50). Additional research is needed on the effectiveness of breastfeeding promotion programs targeting low-income Latinas.
采用随机对照试验研究设计，调查了一项“美国家庭健康”模式的产前干预措施对于提高居住在贫困的纽约市拉丁裔移民中的母乳喂养率的有效性。该干预措施的暴露并没有影响母亲在产后第一周报告的任何母乳喂养（ABF），但确实影响了母亲报告的纯母乳喂养（EBF）。暴露于干预措施的 32%（44/137）的母亲在产后第一周报告了 EBF，而未暴露于干预措施的母亲为 20%（20/101）（比值比 1.92；95%置信区间 1.05-3.52）。在控制家庭收入对 EBF 的负面影响后，该干预措施对 EBF 的积极影响仍然具有统计学意义（调整后的比值比，1.89；95%置信区间，1.02-3.50）。需要进一步研究针对低收入拉丁裔的母乳喂养促进计划的有效性。
