Description of the cohort
This is an research infrastructure now open for cooperation. Persons in for example Betula cohort, NS Alzheimer Registry and the NSHDS can also be found in ALC databases which opens up for extensive description of for example social and living conditions.
More of the database can be found at http://www.ddb.umu.se/ddb-english/cps/alc/
The Linnaeus Database is a unique research resource. It links information from four existing databases, and enables researchers to see new connections between health, lifestyle and ageing. In 2006 the Ageing and Living Conditions Research Programme (ALC) recieved a "Linneaus Grant" from the Swedish Research Council, to conduct research about the aging population's living conditions. The questions which the research programme wanted to investigate required new and larger datafiles. Using information from four different sources, Betula, The Västerbotten Intervention Programme (VIP), Statistics Sweden and The Swedish National Board of Health and Welfare, the new research resource that has been named The Linnaeus Database was created.
Data Sources
Swedish population registry is the base and a number of other registries are added most with focus on ageing and living conditions:
- A Patient register includes Swedish data on hospitalizations 1970 - 2006 with main diagnoses(some limitation) and bi-daignoses and date of hospitalization.
- Cause-of-death register main cause of death 1970 -2006 in Sweden with main cause of death and additional cause and date of death.
