RESUMO
BACKGROUND: Rural US communities experience health disparities, including a lower prevalence of physical activity (PA). However, "Positive Deviants"-rural communities with greater PA than their peers-exist. The purpose of this study was to identify the factors that help create physically active rural US communities. METHODS: Stakeholder interviews, on-site intercept interviews, and in-person observations were used to form a comparative case study of two rural counties with high PA prevalence (HPAs) and one with low PA prevalence (LPA) from a southern US state, selected based on rurality and adult PA prevalence. Interview transcripts were inductively coded by three readers, resulting in a thematic structure that aligned with a Community Capital Framework, which was then used for deductive coding and analysis. RESULTS: Fifteen stakeholder interviews, nine intercept interviews, and on-site observations were conducted. Human and Organizational Capital differed between the HPAs and LPA, manifesting as Social, Built, Financial, and Political Capital differences and a possible "spiraling-up" or cyclical effect through increasing PA and health (Human Capital), highlighting a potential causal model for future study. CONCLUSIONS: Multi-organizational PA coalitions may hold promise for rural PA by directly influencing Human and Organizational Capital in the short term and the other forms of capital in the long term.
