Vitality 90+ is a multidisciplinary research project initiated by Antti Hervonen and Marja Jylhä in 1995. The project focuses on people aged 90 and over residing in Tampere. The project is motivated by rapid changes in the population structure and the increase in longevity. Central research themes in the project include trends in health and functioning, services and informal care, circumstances and subjective experiences of the long-lived, and biology of aging and longevity.
Several kinds of data have been collected with different methods, such as longitudinal mail surveys, health interviews, performance tests, blood samples, life story interviews and register data. The FSD holdings contain longitudinal mail surveys from 1995 onwards./p>
