The purpose of this project is to describe changes in health and functioning among older people. Living conditions and life-style are studied as predictors of health, functioning, need of care and mortality. This multidisciplinary study includes several prospective arms. In 1988 a random sample of people aged 65-84 years were interviewed in their homes. Follow up interviews for them were conducted in 1996 and 2004. During the same years 65-69 year old people were interviewed to capture cohort changes in aging. In 1989 all men born before 1924 and every other woman living in nursing home were interviewed. In 1989 all 75-year-old and 1990 all 80-year-old residents of Jyväskylä were studied in the laboratory with extensive functional testing and clinical examinations. The 75-year-old people were followed up after 5, 10 and 15 years and the 80-year-olds after 5 and 10 years. In addition, register-based data on hospital and long-term care is being updated until the entire cohort becomes extinct. Altogether, 2500 have participated in these studies.
