Distinct challenges exist in the delivery of medical services in correctional facilities, yet little is known about the sources of health information incarcerated patients rely upon to understand and manage their health. Using a nationally representative sample of U.S. incarcerated adults (N = 1,319) from the Programme for the International Assessment of Adult Competencies, we examine patterns in health information seeking behavior. We find incarcerated persons report television (72.9%) and social contacts (61.8%) as their most common sources of health information and use of magazines and books/brochures is significantly related to better health. We argue that asking incarcerated patients how they get health information and using this knowledge to provide them with health information in formats they will use are important steps toward reducing incarcerated individuals' health disparities.
