Evidence-Based, Digitally-Enabled Support and Care for Older Pre-Frail Adults

Frailty and cognitive decline co-occur in ageing populations, motivating scalable multidomain prevention. We present an mHealth app for pre-frail/frail older adults, part of the COMFORTage project, combining: progressive multicomponent exercise with visual guidance; protein-aware meal planning with nutrient feedback; a structured educational path with quizzes; and wearable-supported self-monitoring. In a qualitative think-aloud study with expert participants, participants completed representative tasks across modules and reported the app as easy to use and helpful, with minor suggestions on recipe grouping/localization. The resulted prototype will be assessed under an 18-month randomized study.
