Project Details

Description

The aim of the study is to monitor the iodine fortification in Denmark, which was initiated in 1998.

The monitoring program consists of two main parts:

1. The DanThyr cohort study. Repeated investigation of cohorts, including the iodine status of the population, the intake of iodine-rich diet and supplements, the prevalence rate of goitre, and possible confounding factors.

A cohort of 4649 subjects living in either Aalborg or Copenhagen was investigated in 1997-1998 before iodine fortification was started and a second cohort consisting of 3500 subjects from the same cities was investigated in 2004-2005 about 5 years after iodine fortification was started..

2. The DanThyr Register. Continous monitoring of both overt hyper- and hypothyroidism. All new blood samples analysed for TSH in a population of about 500.000 people in Northern Jutland and Copenhagen are registered. This was started in 1997 and is planned to continue until 2009.
