Researchers are evaluating the effectiveness of the Brazilian Diabetes Prevention Program in preventing type 2 diabetes T2D among adults at high risk. This multicenter, randomized controlled trial involves over 1,300 participants and follows them for three years. The study aims to measure the incidence of T2D and examine factors like body weight, BMI, blood sugar control, physical activity, sleep quality, stress, alcohol use, smoking, and quality of life. It also considers social, cultural, educational, and geographical influences on diabetes risk. Participants are randomly assigned to one of three groups a hybrid program with both in-person and remote counseling, a telehealth-only program delivered via videoconference, or a usual care group receiving lifestyle advice without structured support. Both intervention groups receive 17 individual counseling sessions, 15 support contacts, and 6 group education sessions over 36 months, focusing on healthy eating, physical activity, sleep, stress management, and self-care. The usual care group receives general lifestyle advice during scheduled visits every six months without behavior change support. Throughout the study, participants complete assessments at 6, 12, 24, and 36 months, including blood tests for blood sugar and HbA1c, body weight and BMI measurements, questionnaires on physical activity, diet quality, stress, sleep, alcohol use, smoking, and quality of life. Researchers track medication use and analyze community-level factors related to diabetes risk. The study monitors participants over the full three-year period to evaluate the programs impact and gather detailed health and lifestyle data.
