CONOR is a collection of health data and blood samples from several Norwegian health surveys. When the data collection is complete, CONOR will be a unique database with health data and biological samples of about 200 000 individuals. The purpose of CONOR is investigating the causes of disease. Norway has particular advantages in investigating the causes of disease because it is a surveyable and well-organised little country, where each individual has a unique ID-number. Systematic research may bring new knowledge about e.g. the causes of cancer and other serious diseases. This is the background for the foundation of CONOR, the Cohort of Norway. CONOR is both the name of a collection of health data and blood samples, and of the collaboration between the Norwegian Institute of Public Health and the Universities in Oslo, Bergen, Trondheim and Tromsø.
The CONOR cohort has not been established on the basis of any single hypothesis but is rather a multipurpose study. The ambition was to set up a sufficiently large enough cohort to study aetiological factors for a wide range of diseases. Additionally, this cohort should make it possible to describe Norwegian men and women in terms of distribution of exposures and health status according to time, place and socio-economic factors.
