Researchers are evaluating the Brazilian Diabetes Prevention Program to see how well it prevents type 2 diabetes in adults at high risk over three years. This multicenter, randomized controlled trial involves at least 1,590 adults and also examines factors like body weight, BMI, blood sugar markers, medication use, diet quality, physical activity, sleep, stress, alcohol use, smoking, and quality of life. The study also looks at social, cultural, educational, and geographic factors that might influence the risk of developing type 2 diabetes. Participants will receive either face-to-face or remote care through the Brazilian Diabetes Prevention Program. The face-to-face program includes 28 visits (both group and individual) plus 21 phone or video contacts focusing on diet, self-care, and regular physical activity. The remote program consists of 49 telehealth contacts by phone or video for the same guidance. Additionally, participants receive a hypocaloric diet prescription. The study is coordinated by Hospital Beneficência Portuguesa in São Paulo, Brazil. During the study, participants will be monitored regularly for the development of type 2 diabetes and other health measures such as weight, BMI, blood sugar, and lifestyle behaviors. Researchers will assess diet, physical activity, sleep quality, stress, and quality of life. Data will be collected through visits and contacts over the 36-month follow-up. The study also includes analysis of community-level factors influencing diabetes risk. Safety and adherence will be tracked throughout the trial period.
