OBJECTIVE Few population-based studies have described the epidemiology of subtypes of hyperthyroidism. DESIGN A prospective population-based study, monitoring two well-defined Danish cohorts in Aalborg with moderate iodine deficiency (n=311 102) and Copenhagen with only mild iodine deficiency (n=227 632). METHODS A laboratory monitoring system identified subjects with thyroid function tests suggesting overt hyperthyroidism (low s-TSH combined with high s-thyroxine or s-triiodothyronine… 

Figures and Tables from this paper

Incidence of hyperthyroidism in Sweden.

The incidence of hyperthyroidism in Sweden is in a lower range compared with international reports and the observed geographical differences require further studies.

Increased Incidence Rate of Hypothyroidism After Iodine Fortification in Denmark: A 20-Year Prospective Population-Based Study.

The cautious initiation of the IF program in Denmark caused a sustained increase in hypothyroidism incidence among subjects residing in areas of moderate and mild ID but only among the young and middle-aged participants.

Increasing Incidence of Juvenile Thyrotoxicosis in Denmark: A Nationwide Study, 1998-2012

The IR of JT has increased significantly since 1982-1988 and has continued to increase during the recent 15 years, with a 12.5% increase with each 5-year time period.

Race/Ethnicity and the prevalence of thyrotoxicosis in young Americans.

There are race/ethnicity differences in the prevalence of thyrotoxicosis in Americans aged 12-49 years, and future studies should address whether these differences are due to heritable factors, environmental exposures, or a combination of both.

High age predicts low referral of hyperthyroid patients to specialized hospital departments: evidence for referral bias.

Hyperthyroid patients referred to a specialized hospital unit were younger (GD+MNTG) and had more severe biochemical hyperthyroidism (GD) compared to nonreferred patients, suggesting referral bias may influence hospital-based studies of hyperthyroxine patients, and may hamper external generalization of such studies.

Excess Mortality in Treated and Untreated Hyperthyroidism Is Related to Cumulative Periods of Low Serum TSH

Cumulative periods of decreased TSH increased mortality in both treated and untreated hyperthyroidism, implying that excess mortality may not be driven by lack of therapy, but rather inability to keep patients euthyroid.

Incidence of thyroid dysfunction in an Iranian adult population: the predictor role of thyroid autoantibodies: results from a prospective population-based cohort study

The incidence rate of thyroid dysfunction is high in Isfahan, and higher TPO Ab concentration is its strong predictor, and there is a statistically significant association of hypothyroidism and hyperthyroidism with positive TPOAb.

Graves' Disease and Toxic Nodular Goiter, Aggravated by Duration of Hyperthyroidism, Are Associated with Alzheimer's and Vascular Dementia A Registry-Based Long-Term Follow-Up of Two Large Cohorts

The aim was to determine the risk of dementia in hyperthyroid individuals and whether this was associated with duration ofhyperthyroidism, and to evaluate the relationships between these risks and matched reference populations.

To study the cardiovascular manifestations in newly diagnosed hyperthyroid patients and their outcome with anti-thyroid treatment.

Cardiovascular symptoms and signs, as well as abnormal hemodynamic and dysrhythmias, were frequent among patients with hyperthyroidism and they respond very well to treatment before the structural changes occur in the cardiovascular system.

Clinical management of childhood hyperthyroidism with and without Down syndrome: a longitudinal study at a single center

Thyroid-stimulating immunoglobulin values normalized in exclusively ATD therapy, especially from 2 years on, and TSI values may normalize in GD, notably from the second year of treatment.



Epidemiology of subtypes of hypothyroidism in Denmark.

A population-based study studied incidences of subtypes of primary, overt hypothyroidism in a Danish population cohort and compared incidences in two subcohorts with different levels of iodine intake, observing a higher incidence of hyp Timothyroidism with higher iodine intake.

Incidence of hyperthyroidism in Stockholm, Sweden, 2003-2005.

The total incidence of hyperthyroidism in Stockholm County was found to be 32.7/100,000 per year, of which 75% had GD, and there was no difference in the frequency of smoking between patients with GD and toxic nodular goitre.

The different types of hyperthyroidism in Europe. Results of a prospective survey of 924 patients

The different types of hyperthyroidism in 17 centers of 6 European countries are related to differences in immunological and nutritional status, reflected by a change in the distribution of the different types rather than by achange in the type of hyper thyroidroidism itself.

Incidence of different forms of thyroid dysfunction and its degrees in an iodine sufficient area.

This investigation provides extensive data on incidence of clinical and subclinical thyroid dysfunction and its different forms in an iodine sufficient area.

The thyroid epidemiology, audit, and research study: thyroid dysfunction in the general population.

The level of thyroid dysfunction in Tayside, Scotland is higher than previously reported, and it increased from 1993 to 1996, and the midyear point prevalence of all-cause hypothyroidism rose from 2.2% in 1993 to 3.0% in 1996.

It is concluded that hyperthyroidism remains relatively uncommon in the black population in this region and the incidence of Graves' disease, but not of toxic nodular goitre, appears to be increasing rapidly.

Large differences in incidences of overt hyper- and hypothyroidism associated with a small difference in iodine intake: a prospective comparative register-based population survey.

In such a population, the increase in risk of hypothyroidism should be weighed against the risk of ID disorders such as hyperthyroidism due to multinodular toxic goiter, even if the population is moderately iodine-deficient.

Incidence of juvenile thyrotoxicosis in Denmark, 1982-1988. A nationwide study.

It is concluded that thyrotoxicosis is a rare disorder in Danish children under the age of 15 years, and the incidence increases with age, and female preponderance is significant from early childhood.

The incidence of hyperthyroidism in Austria from 1987 to 1995 before and after an increase in salt iodization in 1990

The time course of different types of HT following the increase in salt iodization could be divided into two phases: an increase in the incidences of HT with peaks after 1–4 years and a subsequent decrease, the only exception being scGD.
