Background: Religious institutions play a crucial role in health promotion and hold significant influence in the public health field. Aim: The aim of this review is to examine outcomes of health-promoting interventions involving the use of mosques as the intervention venue, its role in promoting health behavior change, and the role of theory in each intervention. Methods: A scoping review was conducted across 17 databases for relevant publications published up to and including August 2023 that involved the use of mosques as the intervention venue. Fourteen articles met inclusion criteria and were reviewed. Results: The studies featured a wide range of interventions. However, only eight of these studies integrated theoretical frameworks into their approaches, indicating a need for more structured guidance in this field. These theoretical frameworks included Participatory Action Research (PAR), the theory of planned behavior, behavior-change constructs, the patient-centered outcomes research (PCOR) framework, and prolonged exposure techniques within Islamic principles. The review identified three main health-focused intervention categories: mental health, prevention, and communication, each providing valuable insights into initiatives within Muslim communities. Conclusions: This review underscores the significance of inclusive and culturally sensitive health interventions, emphasizing the effectiveness of faith-based approaches in improving health outcomes, promoting positive health behaviors, and addressing communication and cultural barriers. The reviews findings stress the need for further research that incorporates theoretical frameworks and tailored interventions to meet the specific cultural needs of these communities, ultimately contributing to enhanced well-being within them.
