Danish National Health Survey (DNHS)
The DNHS aims to monitor the health and well-being of the Danish population. Formerly known as the DHMS, the study began in 1987 with 8,363 participants at baseline. Participants were followed up in 1994, 2000, and 2005, ending with 21,832 participants. These participants were then followed up through the Danish National Cohort Study (DANCOS), a registry-based follow-up database, to calculate the impact of risk factors on mortality through linkage. The study, now known as the DNHS, followed up participants from the DHMS alongside new participants, with 177,639 participants in total in 2010. Participants are from six mutually exclusive random subsamples: one from each of the five Danish regions and one national sample. They have been followed up in 2013, 2017, 2021, and 2023, with 183,372 participants as of 2017.
