Objectives: Iodine fortification (IF) induces an initial increase followed by a decrease in the incidence of hyperthyroidism in the population. Also, the sex-, age-, and subtype distribution of hyperthyroid cases changes after IF. The risk of atrial fibrillation (AF) in hyperthyroid patients is influenced by these factors. Therefore, we aimed to examine how the association between incident hyperthyroidism and atrial fibrillation was affected by an IF increasing the population ...

Background: Few studies have scrutinized the spectrum of symptoms in subclinical hypothyroidism.Methods: From three DanThyr cross-sectional surveys performed in the period 1997 to 2005, a total of 8,903 volunteers participated in a comprehensive investigation including blood samples and questionnaires on previous diseases, smoking habits, alcohol intake, and education. From the three surveys we included patients with unknown subclinical hypothyroidism (<...

Objectives: Hypothyroid patients report a diversity of symptoms at disease presentation. We studied how useful symptoms are to predict hypothyroidism, and if this may vary between subgroups of patients.Methods: Patients newly diagnosed with overt autoimmune hypothyroidism (n=140) were prospectively identified in a population by linkage to diagnostic laboratory databases, and we concomitantly enrolled individually sex and age-region matched contr...

Introduction: Autoimmune thyroid disease is associated with other autoimmune diseases. However, most studies are register-based cohort studies or investigate selected patient populations. In a large national cross-sectional population-based study, we investigated positivity of thyroid peroxidase- or thyroglobulin-antibodies (TPOAbs or TgAbs) in association with non-thyroidal autoimmune disease.Methods: As part of The Danish Investigation of Iodine Intake...
