Adaptation of the PREDIMED Intervention for Medically Underserved Prostate Cancer Patients Through Intervention Mapping

Prostate cancer is the most common non-cutaneous malignancy for men and disproportionately affects those with low socioeconomic status, particularly men from racial and ethnic minority populations. This study describes the development of a culturally tailored Mediterranean diet intervention for medically underserved Black and Hispanic men with prostate cancer, using the Intervention Mapping Adaptation (IM ADAPT) framework. Conducted at a county safety-net hospital in Houston, Texas, which serves a population with high medical needs and low socioeconomic status, the project aimed to ensure the intervention was culturally relevant and evidence-based. A collaborative process was used, involving community scientists and patient stakeholders to identify dietary barriers and preferences, while existing interventions were reviewed for cultural fit. Guided by the six steps of the IM ADAPT framework, stakeholder feedback was incorporated throughout the adaptation process. The result was a culturally adapted intervention that included tailored dietary modifications, food provision strategies, and educational materials specifically designed for Black and Hispanic men. The finalized intervention is ready for pilot testing and may serve as a model for adapting evidence-based interventions to address health disparities in other racial and ethnic minority populations affected by cancer.
