The HUNT study - a longitudinal population health Study in Norway.
The Nord-Trøndelag health study (HUNT) is one of the largest health studies ever performed. It is a unique database of personal and family medical histories collected during three intensive studies. The fundamental strategy is to earn and maintain the confidence of the population we work in and with as is necessary for any successful population study. This strategy has been successful and has resulted in extraordinarily high participation rates. There is enthusiastic public and political support for HUNT and of the HUNT Research Centre. This has created a good basis for further health surveys in the county and an excellent research environment.
HUNT 1 was carried out in 1984-1986 to establish the health history of 75,000 people.
HUNT 2, carried out in 1995-1997, focused on the evolution of the health history of 74,000 people. This included blood sample collection from 65,000 people. The data that accompany biospecimens in the biobank are stored in secured computer systems that run complex database management and analysis software.
HUNT 3 was completed in June 2008. 93,210 people were invited to participate in the study, and as of the 6th of June, 2008, 48,289 people participated (52% participation rate). The data, collected by means of questionnaires, interviews, clinical examinations and collection of blood and urine samples, will be ready for analysis in January 2009.
Young-HUNT is the adolescent part of HUNT including participants aged 13-19 years. Data gathering took place in Young-HUNT1 (1995-97), Young-HUNT2 (2000-01), and Young-HUNT3 (2006-08). Data collection included self-reported questionnaires, structured interviews, clinical measurements and buccal smears.

HUNT 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, HUNT is a database with information about approximately 120,000 people that integrates family data and individual data and can be linked to national health registries.
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.
The HUNT study is reinforced and supplemented by cross referencing with registries at the regional level (Registries such as radial and hip fractures, venous thrombosis, lung embolism, ischemic heart disease and stroke) and with registries at the national level (The Cancer Register, The Medical Birth Register, and The National Health Insurance Register). Additionally, Statistics Norway provides necessary information from The Population Census Register and The Family Register to create a genealogical database ("family trees").
