Relational community engagement may be a powerful approach with multiple health outcomes. Relational community engagement has the potential to promote health and involves collaborative efforts between multiple stakeholders. The COVID-19 pandemic further highlighted the centrality of community engagement in health crises. Challenges continue to persist, however, in genuinely engaging and empowering communities for better health outcomes. Understanding the multi-level and complex relational nature of community engagement is essential to comprehend its influence on health at micro, meso, and macro scales of influence. The purpose of this narrative review was to synthesize the literature on relational community engagement within varied health interventions at the three major system levels (micro, meso, and macro) to support the development of future research agendas. At the micro level, relational community engagement interventions demonstrated a range of positive outcomes including: increased sense of control, satisfaction, positive behavior, improved knowledge, behavior change, empowerment, and overall positive health and social outcomes. At the meso level, relational community engagement interventions resulted in increased trust between stakeholders and groups/teams, and increased community senses of ownership of interventions, decisions, structures. At the macro level, relational community engagement interventions influenced broader societal factors and had positive impacts on health policy and governance including collaboration between sectors and communities as well as increased access to services. The review highlights the potential versatility and effectiveness of interventions that prioritize relationships, health promotion, and social change while underscoring the significance of holistic and community-centered approaches in addressing diverse health and social challenges.
