AIMS: The Danish Health Examination Survey (DANHES 2007-2008) was carried out by the National Institute of Public Health, University of Southern Denmark, in 13 Danish municipalities in 2007-2008. The focus of the survey was diet, smoking, alcohol, and physical activity. The aim of the survey was to establish a research database for future cross-sectional and follow-up studies.
METHODS: DANHES 2007-2008 included internet-based questionnaires and a health examination. There were two different questionnaires: a basic questionnaire on socio-demography, health behavior, self-reported health status, and living conditions, and a supplementary food frequency questionnaire. The health examination contained measurements of blood pressure, resting heart rate, height, weight, fat percentage, waist and hip circumference, blood and hair samples, spirometry, bone mineral density, physical performance, muscle strength, and aerobic fitness.
RESULTS: A total of 76,484 people completed the basic questionnaire, and 18,065 adult individuals participated in the health examination, corresponding to a response rate of 14% and a participation rate of 10%, respectively.
CONCLUSIONS: The database from DANHES 2007-2008 is unique in its size and diversity of measurements and questionnaire contents. Data can be linked to various registers through the Danish civil registration system, and blood samples are stored in a biobank allowing for genetic analyses. Hence, DANHES 2007-2008 forms the basis for future research projects with a focus on health behavior and prevention of lifestyle-related diseases.
