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.
The main objective of the FINGER study is to find out if a multi-domain intervention could prevent cognitive decline among older people. With this intervention we also aim to investigate the effect of the multidomain intervention on disability, quality of life, depressive symptoms, the use of health care services and vascular risk factors.
Participants of the FINGER study have previously taken part in population-based non-intervention studies. They have an increased risk of cognitive decline. At the beginning of the study they are 60-77 years old. The FINGER study enrols approximately 1200 participants in six centers in Finland: Helsinki, Kuopio, Oulu, Seinäjoki, Turku and Vantaa.
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.
The Health 2000 Survey, carried out in 2000-2001 in Finland, was coordinated by the National Institute for Health and Welfare, THL (the former National Public Health Institute) in co-operation with an extensive network of organizations and experts. The aim of the survey was to provide information on major public health problems, their causes and treatment, health service needs and utilization as well as functional and working capacity. The data for the survey were collected in comprehensive health examination including blood sampling, in interviews and in self-administered questionnaires. The nationally representative sample included 8,028 persons aged 30 or over of whom 85% participated in the health examination conducted at 80 areas in the mainland Finland. In addition, 1,894 young adults (18-29 years) were invited to the health interview and fill in the questionnaire. Further, 1,278 people who had taken part in Mini-Finland Health Survey carried out in 1978-1980 were invited to the re-examination.
The follow-up of the Health 2000 Survey, the Health 2011 Survey, was carried out in 2011-2012. All members of the Health 2000 sample (n=8,135), who were living in Finland in 2011 and had not refused requests to be invited to further studies, were invited to the Health 2011 Survey. In 2011, they were at least 29 years of age. A total of 59% of them participated in the health examination conducted at 59 areas in Finland. In addition, a new random sample of young adults (aged 18-28, n=1,994) was taken. A total of 415 of them were invited to the health examination and the rest of them (1,579) received only the postal questionnaire. Further, 920 people who had previously taken part in the Mini-Finland Health Survey and invited to re-examination in 2001 were invited.
The Health 2000/2011 cohort is also continuously followed-up by linkage to Finnish nationwide registers.
STROKOG is a consortium of longitudinal studies of cognitive disorders following stroke, TIA or small vessel disease. Developed under the auspices of VASCOG (Society for the Study of Vascular Cognitive and Behavioural Disorders), it is the first international effort to harmonise work on post-stroke dementia and is being led by CHeBA researchers.
The consortium brings together studies that have examined post-stroke or other high vascular risk cohorts longitudinally, with cognitive decline and dementia (including sub-types) as primary outcome variables. The included studies (N=27; total sample of more than 10,000 individuals, representing 17 countries) have rich neuropsychological and MRI data, and some recent studies (n=3) have included amyloid imaging in sub-samples. A number of studies have CSF and/or plasma available for biomarker studies, and participant enrolment in brain banks for neuropathology.

The Northern Finland Birth Cohort Studies is an epidemiological and longitudinal research program which aims to promote health and well-being of the population. The prospective data collected from the Northern Finland forms a unique resource, allowing to study the emergence of diseases which can be based on genetic, biological, social or behavioural risk factors.
NFBC includes two longitudinal and prospective birth cohorts of women and offspring collected at 20-year intervals from the same provinces of Oulu and Lapland: The NFBC1966 was set with an expected date of birth in 1966, comprising of 12,068 mothers and 12,231 children (prospective data collection from maternity cards since 16th gestational week on average), and the NFBC1986 with an expected date of birth between July, 1st 1985 and June, 30th 1986, comprising 9,362 mothers and 9,479 children (prospective data collection from 10th gestational week).

Helsinki Birth Cohort Study (HBCS) 1934-44 is a unique birth study including 13,345 subjects in the epidemiological cohort. The cohort is a longitudinal study cohort with data throughout the life span including prenatal life, early childhood and later life. Besides extensive epidemiological data over 2000 subjects have been randomly selected for a clinical part. The subjects have been followed up clinically for over one decade with extensive phenotypic data available including metabolic data, dietary information as well as other lifestyle data. Psychological factors including personality, depression and anxiety has been focused upon.
