A digital service for healthy behaviors

Longlife Active


Longlife Active- an individually tailored digital service to promote healthy and sustainable behaviors supported by AI


Increased levels of physical activity and improved dietary habits have remarkable important effects on the individual health and well-being as well as on public health. The ultimate goal of this research project is to improve well-being and longevity through sustained healthy dietary and physical activity behaviors. Digital technology has potential to assure continuity of healthy behaviors based on the needs and preferences of the individual.


This project aims to collaboratively develop a web-based service for personalized support for behavior change based on artificial intelligence, health coaching and social support, and to evaluate the implementation, behavior change outcomes and well-being.


The project is planned based on a framework for developing behavioral interventions and entails three phases. The initial phase, Intervention planning, includes a co-development study which comprises workshops with researchers, program developers and potential target users. The second phase, Intervention optimization, consists of a pilot study testing a prototype of the service and evaluating the feasibility and acceptance of the included functions. The third phase, Evaluating intervention implementation and outcome, is planned as a real world observational research study.


Digital technology has potential to reach many individuals in short time, to contribute to systematic and sustained disease prevention and health promotion, and to diminish inequalities in health. This project aims to develop and evaluate a web-based service that can be integrated in ordinary services of primary health care, workplace health promotion and pharmacies and enhance the support for healthy behaviors. The purpose of the project is to increase the knowledge and understanding of how digital technology should be optimized to be personalized and user-friendly, to serve as a complement to advice on physical activity and a healthy diet.
