Biobank and Databank

HUNT Research Centre collaborates with national and international research groups on some of the important health topics facing our world today using the most modern techniques and our state of the art biobank.

Today, the HUNT Study is a database with health survey data about approximately 120,000 people.

Repeated examinations and follow-up of the same population make it possible to ascertain changes in health and vital status at individual and family levels.

Merging with other registries

The HUNT Study is reinforced and supplemented by possibilities for research projects of merging HUNT data with information from registries at the regional and national level. Additionally, Statistics Norway provides necessary information from The Population Census Register and The Family Register to create a genealogical database ("family tree").
