Abstract
Background: A healthy diet is an important component of preventive medicine. With the changing landscape of medicine, physicians are encountering more challenges in educating patients about a healthy diet, so finding innovative ways to educate patients is imperative. This study investigated the effectiveness of an innovative educational intervention based on the United States Department of Agriculture-recommended MyPlate diet. Methods: Based on the assessed need for dietary education, patients were exposed to an educational video and received a handout on the MyPlate diet. The educational video was created to be culturally relevant with patient-informed edits. The handout was taken from www.ChooseMyPlate.gov. The patients who received the intervention were compared to those who were not exposed to the intervention. Data were collected in a primary care clinic for an underserved population in fall 2018 and analyzed in spring 2019 through patient-completed surveys and physician reporting on patient interactions. Data were analyzed using descriptive statistics, t tests, chi-squared models, and repeated measures analysis of variance. Results: Among 320 patients, 169 patients were exposed to the educational intervention. Intervention patients had better knowledge of the MyPlate diet (P=0.009), felt it would be easier to change their diet (P=0.03), and were more motivated to have conversations about diet with their physician (P=0.04) compared to those who were not exposed. Patients also enjoyed the video overall. Conclusion: This study shows that using multiple modalities including a patient-centered video and handouts to educate patients about diet is enjoyable to patients and effective in teaching, motivating change, and encouraging communication between patients and physicians.
