Below you will find a brief summary of the four sources on which the Linnaeus database is based.
Is a research project and a database at the Department of Psychology at Umeå University.
Since the 80s, the Betula project has examined the cognitive functions of 4 200 randomly chosen participants living in Umeå. Among other things, the participants do memory tests and answer questions about their health and family situation. Since these participants are tested every five years, the project can follow development of memory and health over time. One of the purposes is to detect early signs of dementia.
The Västerbotten Intervention Programme (VIP) is a project and a database owned by the Västerbotten County Council.
The VIP database started in 1985 to counteract the high prevalence of cardiovascular disease (CVD) in the county of Västerbotten. Up until 2006, about 106 000 health checks had been performed among the local population at the time that they reached 40, 50 and 60 years old. The health checks includes fitness-, nutrition-, and medical tests. Participants may also fill out a questionnaire about lifestyle, work and family etcetera.
Provides records of i.a. income, education, family and work, and includes the entire Swedish population. Selected parts of this information is connected to the Linnaeus database. For instance the Longitudinal integration databae for health insurance and labour market studies (LISA).
