Peer counseling (PC) breastfeeding support programs have proven effective in increasing breastfeeding duration in low-income women.
This study aimed to describe program participants and breastfeeding duration in a PC program according to (1) timing of enrollment (prenatal vs postnatal) and (2) breastfeeding status at program exit (discontinued breastfeeding, exited program while breastfeeding, and completed 1 year program) to improve understanding of how these groups differ and how services might be optimized when resources are limited.
This study is a secondary analysis of data from low-income women enrolled in a PC breastfeeding support program. Participant characteristics and breastfeeding duration were described using chi-square tests, analyses of variance, and logistic regression.
Postnatal enrollees had longer breastfeeding duration than prenatal enrollees (F < .001) and were more likely to be older, to be married, to be more educated, and to have prior breastfeeding experience (each variable P < .01). Women who withdrew from the program while breastfeeding were more demographically similar to those who discontinued breastfeeding prior to 1 year than to those who continued in the program breastfeeding for 1 year, although they breastfed for significantly longer at exit (mean ± SD = 27.8 ± 14.8 weeks) compared to women who discontinued breastfeeding while in the program (15.7 ± 13.3 weeks) (P < .001).
It may be advantageous for peer counselors to direct fewer resources to later postnatal enrollees and more to prenatal or early postnatal enrollees. It may also be advantageous to focus on supporting women at high risk of discontinuation rather than on retaining women who choose to withdraw from the program while breastfeeding.
同伴咨询（PC）母乳喂养支持项目已被证明在增加低收入女性的母乳喂养时长方面有效。
本研究旨在根据（1）入组时间（产前与产后）和（2）项目结束时的母乳喂养状况（停止母乳喂养、在母乳喂养时退出项目、完成1年项目）描述PC项目的参与者及母乳喂养时长，以增进对这些群体差异的理解，以及在资源有限时如何优化服务。
本研究是对参加PC母乳喂养支持项目的低收入女性数据进行的二次分析。使用卡方检验、方差分析和逻辑回归描述参与者特征及母乳喂养时长。
产后入组者的母乳喂养时长比产前入组者更长（F <.001），且更有可能年龄较大、已婚、受教育程度更高以及有过母乳喂养经历（各变量P <.01）。在母乳喂养时退出项目的女性在人口统计学特征上与在1年前停止母乳喂养的女性比与继续母乳喂养1年的女性更为相似，尽管她们在退出时的母乳喂养时间（均值±标准差 = 27.8 ± 14.8周）明显长于在项目期间停止母乳喂养的女性（15.7 ± 13.3周）（P <.001）。
同伴咨询师将较少资源导向产后较晚入组者而将更多资源导向产前或产后早期入组者可能是有利的。关注支持有停止母乳喂养高风险的女性而非留住那些在母乳喂养时选择退出项目的女性可能也是有利的。
