- Detailed Description
This project aims to redesign and optimize a deep-structure culturally-tailored healthy eating program and test its effectiveness in improving dietary outcomes, anthropometric, and blood pressure among 75 diverse Latinos, compared to surface-level messages. The WELCOME study will be based on the RE-AIM framework with improved reach, adoption, implementation, and maintenance strategies. The intervention arm is a deep-structure cultural tailored text messages for distinct Latino heritages (e.g., Caribbean and non-Caribbean) informed by mixed-methods formative research, compared to surface-level healthy eating messages based on the USDA My Plate Spanish version. The program runs for 6 months: 2-months delivery phase + 2-months reinforcement phase + 2-months maintenance phase.
