Abstract
In the HUNT Study, all residents aged ≥20 years in the Nord-Trøndelag region, Norway have been invited to repeated surveys since 1984-86. The study data may be linked to local and national health registries. The HUNT4 survey in 2017-19 included 56 042 participants in Nord-Trøndelag and 107 711 participants in the neighboring Sør-Trøndelag region. The HUNT4 data enable more long-term follow-up, studies of life-course health trajectories, and within-family studies. New measures include body composition analysis using bioelectrical impedance; a one-week accelerometer recording; physical and cognitive testing in older adults; measurements of hemoglobin and blood cell counts, HbA1c and phosphatidylethanol; and genotyping. Researchers can apply for HUNT data access from HUNT Research Centre if they have obtained project approval from the Regional Committee for Medical and Health Research Ethics, see www.ntnu.edu/hunt/data.
