This pilot project will determine whether a diet culturally-adapted to Puerto Ricans can effectively decrease cardiometabolic risk for diabetes. This will help define a culturally-appropriate, feasible, and sustainable diet intervention aimed at reducing type 2 diabetes and obesity outcomes.
This pilot intervention will culturally-tailor a diet to the Puerto Rican adult population based on staple foods as well as culturally-appropriate strategies to reduce cardiometabolic risk factors of type 2 diabetes and obesity. Based on preliminary results from studies in the island, investigators will conduct a 4-month, 2-arm intervention among 200 adults (100 per arm) ages 25-65 living in Puerto Rico with at least 2 of 5 cardiometabolic risk factors. The two arms are: (1) intervention group consisting of culturally-appropriate advice in an initial individual session with daily text messages for 2 months (delivery phase); (2) control arm of standard general nutritional advice at the initial individual session, and text messages for 2 months. A reinforcement phase of 2-months will follow to repeat the education and text messages. Investigators will measure changes in cardiometabolic risk factors and in eating-behaviors and psychological measures.
