Background Evidence is central to all maternal and child health (MCH) decision-making processes, continuously interacting with and influencing our work. There is a growing emphasis in MCH on using evidence-based approaches when addressing public health challenges, but the field lacks a unified understanding of what constitutes evidence. MCH must operate from an expansive understanding of evidence that centers community voice and acknowledges the role of evidence prioritization in achieving equitable population-level outcomes. Call to Action What we consider valid evidence has immense implications for MCH practice, including whose work is deemed worthy of funding and replication. The authors advocate for shifting the field's evidence paradigm from being primarily focused on research findings to also recognize the importance of community-rooted evidence. Contextual and experiential evidence, alongside research evidence, should be considered for two purposes: (1) to support the effectiveness of a given practice generally, and (2) to support that the practice will work in specific contexts. Putting this shift into practice requires explicit power shifting - the MCH workforce must cede power to those who have been historically barred from participating in and guiding research. To facilitate this, MCH professionals must build skills in communication, equitable leadership, and change management. Conclusion The MCH workforce should position communities to set their own priorities and define, develop, and disseminate evidence representative of their priorities. Evidence co-creation is key to establishing and sustaining transformative relationships between community members and Title V programs, shifting power structures to build upon existing community leadership and assets.
