Development of a Digital Personalised Nutrition Tool for Adolescents Undergoing Cancer Treatment

This study aims to develop and test MybYte, a smartphone tool designed to support personalised nutrition for teenagers aged 12-18 undergoing cancer treatment. MybYte will ask short questions about eating, appetite and treatment-related symptoms and provide personalised nutrition advice developed by healthcare professionals. In Phase 1, around 15 teenagers will help co-design and refine the tool through interviews and feedback. In Phase 2, around 15 newly diagnosed teenagers will use MybYte for one week each month over six months, alongside routine assessments of nutrition, body composition, taste, energy needs and quality of life. The study will assess whether MybYte is acceptable, practical and helpful for teenagers receiving cancer treatment.
