Testing a Digital and Counseling Program to Support Healthy Eating and Activity in Adults 60 and Older After Liver or Kidney Transplant

What this Trial Is About

Researchers are evaluating whether a doctor-led lifestyle counseling program, supported by two personalized smartphone apps called Gamebus and Nutrida, is practical and helpful for improving healthy eating and physical activity in adults aged 65 years or older who have had a liver or kidney transplant. The study aims to see if participants can safely use these apps and follow the program, and whether this combined approach can improve diet, activity, body measurements, and routine lab values related to metabolic health. All participants first receive medical counseling on healthy diet and physical activity. After 12 weeks, they begin using the two digital support apps at home to help maintain behavior change. Each participant serves as their own comparison, with results after starting the apps compared to their own progress before using them. The intervention combines counseling activities with the use of these digital tools designed to promote a healthy lifestyle. Participants attend three study visits over 24 weeks. At each visit, they complete questionnaires, undergo body and body composition measurements, review their recent diet, and receive lifestyle guidance. The study team measures adherence to the digital lifestyle program between weeks 12 and 24 and also evaluates changes in diet, physical activity, body measurements, and metabolic lab tests at baseline, 12 weeks, and 24 weeks. The study helps determine if this digital-supported lifestyle program is feasible and acceptable for older transplant recipients.
