Abstract

OBJECTIVE: To assess thyroid autoimmunity among elderly people living in an area with low iodine intake compared to the sustained recommended iodine intake from a natural source, and to estimate the importance of migration. DESIGN AND SETTING: Iodine content of drinking water is highly different in the Danish towns Randers and Skagen. We collected blood and spot urine samples from 430 long-term Randers and Skagen dwellers aged 75-80 years, who filled in a questionnaire. We measured thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TGAb) in serum and iodine and creatinine in urine. RESULTS: Participation rate was 47% (n=212 (men/women 82/130) in Randers; 218 (84/134) in Skagen). Iodine deficiency prevailed in Randers while Skagen dwellers were iodine replete (median urinary iodine 74μg/24h vs. 184μg/24h, p
