Randomized trial demonstrates the effectiveness of a mobile health app in supporting older pre-frail adults, suggesting positive implications for community health.
Frailty and cognitive decline co-occur in ageing populations, motivating scalable multidomain prevention. We present an mHealth app for pre-frail/frail older adults (≥55), 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 (n=5; 4 non-expert smartphone users, 1 highly confident), 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.
