Breastfeeding equity is a critical component of nutrition-related equity. Breastfeeding rates in the United States are strongly correlated with poverty and race. Communities and Hospitals Advancing Maternity Practices (CHAMPS) is a multi-sectoral, policy, system, and environmental initiative which has significantly increased breastfeeding rates among black populations. CHAMPS was launched in Mississippi (MS) in 2014. Since then, MS CHAMPS has enrolled 93% of MS birthing hospitals and the number of WHO Baby-Friendly hospitals located in MS has risen from 0 to 13. This project will provide an evaluation of MS CHAMPS using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. In addition, the project will demonstrate and disseminate solutions to inequitable breastfeeding rates. The specific aims of this project include: analyzing, publishing, and disseminating the results of the MS CHAMPS RE-AIM analysis; sharing findings with community partners and stakeholders; and enabling CHAMPS to develop an increasingly effective, sustainable, and scalable breastfeeding equity model. Statistical analysis of hospital breastfeeding rates, by race, and tests for statistically significant improvements will be used. A thematic analysis approach will be used to analyze all qualitative data.
