Application of the consolidated framework for implementation research to understand implementation context of a cardiovascular disease risk-reduction intervention in rural churches.

Lifestyle interventions can be effective in lowering heart disease risk, but hard to access for those living in rural areas of the USA for geographic, cultural, and other reasons. Interventions implemented in community settings with partners such as churches are promising for reaching community members and improving health outcomes. Our goal was to identify and understand the role of organizational factors that affected the implementation of an intervention implemented in 12 rural churches to lower heart disease risk by promoting behavior change. By analyzing interview discussions and program documents, we found four factors related to church climate and culture that may have a role in intervention implementation: (i) whether health promotion activities were supported by religious beliefs within the church, (ii) whether churches had a prior history of health activities, (iii) whether church stakeholders expressed a need for the intervention, and (iv) church leader support for the intervention. Attention to these factors may help to improve future implementation of church-based interventions in rural settings.
