Nord-Trøndelag Health Study, The (HUNT)

The HUNT Study (an acronym for the Norwegian name:Helseundersøkelsen i Nord-Trøndelag) constitutes a large population database for medical and health-related research. So far three health surveys of the general adult population in the Nord-Trøndelag County, Norway, have been completed: HUNT1 in 1984–86, HUNT2 in 1995–97, and HUNT3 in 2006–08. Major public health issues as cardiovascular disease, diabetes, obstructive lung disease, osteoporosis and mental health are explored, in concordance with current priorities of the health authorities. Adolescents aged 13-19 years have been invited to the Young-HUNT Study initiated at HUNT2 with a partly overlapping scientific program to the adults surveys.
