BACKGROUND: Peer support programs may be effective for supporting breastfeeding among diverse groups, and in reducing disparities. This study provides insight regarding the implementation and outcomes of a peer breastfeeding support program. RESEARCH AIMS: (1) to examine how participation affected the outcomes of breastfeeding motivation, confidence, and coping strategies
and (2) to evaluate satisfaction with the program. METHOD: This was a cross-sectional, retrospective study. Seven pilot sites in the United States uniquely implemented a federally-funded peer support program for low-income women. Data were collected using a survey and focus groups/interviews. Over 12 months, 1,296 women participated, comprising 615 peer support pairs. A total of 401 women responded to the survey. Twenty-three focus groups and 63 interviews were conducted across the seven sites. RESULTS: Participants who enrolled in the program during pregnancy: CONCLUSION: Effective operation strategies of the peer breastfeeding support program have significantly influenced participant satisfaction. Introducing peer support for low-income women to share their breastfeeding experiences would be beneficial in enhancing breastfeeding rates. However, the generalizability of these findings may be limited to this U.S. federally-funded peer support program.
