PreventIT sees modern developments in mobile technology as an excellent starting point to enable active and healthy ageing, and therefore aims to develop a personalised behavioural change intervention at the time of retirement that is based on exercises and activities that are embedded into daily life. In order to realize this ambitious aim, PreventIT brings together a strong consortium with partners from several European research institutions, academic hospitals, and companies that together have the necessary skills and experience to bring this project to fruition.
