The Experience of Spanish-Speaking Latinos in Maintaining Dietary and Physical Activity Changes after the National Diabetes Prevention Program

Background: The impact of the National Diabetes Prevention Program (N-DPP) for Latinos post-program participation is uncertain. Purpose: We examine the experiences of Latinos who participated in the N-DPP in continuing the dietary and physical activity changes learned in the program. Methods: This is a qualitative descriptive interview study. We recruited 19 Latino adults who participated in a culturally and linguistically adapted N-DPP. Thematic analysis was used to analyze the data and report emerging themes. Results: Participants discussed how the program improved their knowledge about healthier lifestyles, and shared specific tools and strategies that they used to maintain learned program behaviors. Factors related to discontinuation of behaviors included missing the group social support, losing commitment over time, and avoiding family conflict. Maintenance of behaviors was mainly facilitated by family support. Discussion: Our study suggests that Latinos who participated in the N-DPP gained useful knowledge on healthier behaviors and learning strategies for implementation into their lifestyle, but barriers remain. Translation to Health Education Practice: Adaptations of the program for Latinos should consider the important roles of family and social support to improve N-DPP outcomes for this group and better support Latinos in preventing diabetes.
