The Vitality 90+ Study (in Finnish: Tervaskannot 90+) is a multidisciplinary project focusing on longevity and the oldest-old. The sub-projects address the biological basis of aging, predictors of health, functioning and longevity, old age as an individual experience, and the need for and use of care and services. The research is motivated by the rapid changes in the population structure and by the increase in real longevity.

Data was collected through mailed surveys with whole cohorts of people aged 90+ in Tampere, face-to-face interviews and performance tests and blood samples. The mailed surveys were conducted with all community-dwelling people in 1996 and 1998, and with both community-dwelling and institutionalized people four times since 2001.
