Key Features

HUNT4 70+ is a sub-cohort of persons aged ≥70 years in the fourth survey of the Trøndelag Health Study (HUNT), established to provide data for aging research.

This population-based sample consists of 9956 individuals from the original HUNT catchment area, included between August 2017 and February 2019. In addition, an urban sample of 1743 persons was included in Trondheim city during October 2018–June 2019.

HUNT4 70+ covers comprehensive aspects of aging health, including clinical examinations, performance-based tests of physical and cognitive function, questionnaires, and biological samples.

High participation rates among the old and frail were obtained by examination in private homes and nursing homes when needed (15% of the participants).

The data can be linked to all national registers in Norway, such as cause of death, prescription, health-care utilization, and diagnosis registries.

Data access requires approval from a Norwegian Research Ethics Committee before application to the HUNT Research Centre. Contact HUNT Research Centre for collaboration and more info (ntnu.edu/hunt).
