Addressing Health Disparities through Community Participation: A Scoping Review of Co-Creation in Public Health.

Background: There is general agreement regarding the relevance of community involvement in public health policy, practice, and research to reduce health inequities.
Objective: This review aims to analyse the experiences of community engagement in public health actions, with particular attention to methodologies used and how community participation is articulated.
Method and Analysis: We searched the Web of Science, EBSCO, and ProQuest for scientific articles published in peer-reviewed journals. We recorded methodological aspects, the approach to equity, actors that participated in the actions, and participation of the community in different phases (agenda setting, design, implementation, and evaluation).
Results: Of 4331 records, we finally included 31 studies published between 1995 and 2021. Twelve studies referred to Community-Based Participatory Research as the framework used. The actions addressed equity, mainly by tackling economic vulnerability (n = 20, 64%) and racial discrimination (n = 18, 58%). Workshops were the most used method. Participation was frequently observed in the design and implementation phases of the action, but it was reduced to community feedback in the evaluation.
Conclusions: Co-created public health actions offer the opportunity to reduce health inequity and promote social change; yet, further effort is needed to involve communities in the entire cycle of decision making.
