In order to examine whether iodine supplements may have caused a global decline in sperm concentrations during the past several decades, the synchronicity of the decline in mean sperm counts and the introduction of iodine supplements was analyzed statistically. A positive correlation between the incidence of thyroid disease and sperm counts has been detected in Europe. In addition, it has been ...

Iodine is one of the best-characterized environmental factors associated with autoimmune thyroid disease (ATD). Epidemiological studies have shown that ATD incidence has increased following the introduction of salt iodination in the 1920s; in addition, ATD patients can improve upon iodine restriction. In animal models such as BioBreeding/Worcester and Buffalo rats, obese chicken strain, and non...

After the 1918 Influenza Pandemic which killed an estimated 30 million people, governments financed research on the Pandemic’s causes. Over 25 years, influenza viruses were isolated and methods for killing them with various agents discovered. Iodine was the most effective agent for killing viruses, especially influenza viruses. Aerosol iodine was found to kill viruses in sprayed mists, and solu...

Thyroid cancer (TC) is the most common endocrine malignancy and in most countries, incidence rates are increasing. Although differences in population iodine intake are a determinant of benign thyroid disorders, the role of iodine intake in TC remains uncertain. We review the evidence linking iodine intake and TC from animal studies, ecological studies of iodine intake and differentiated and und...

BACKGROUND A common recommendation for the treatment of hypertension is dietary salt intake restriction. However, dietary salt is one of the major sources of iodine. This study evaluated the association between dietary salt restriction and iodine deficiency among adults in the United States. METHODS Multiple regression models, which controlled for confounders, were used to evaluate the associ...

Iodine deficiency early in life impairs cognition and growth, but iodine status is also a key determinant of thyroid disorders in adults. Severe iodine deficiency causes goitre and hypothyroidism because, despite an increase in thyroid activity to maximise iodine uptake and recycling in this setting, iodine concentrations are still too low to enable production of thyroid hormone. In mild-to-mod...

In the fall of 1991, the incidence of goiter was determined in I07X male and female school children in Kermanshah city. The study was considered from two view points i.e., clinical examinations and measurements of levels of iodine excreted in urine, and was performed in three age groups: 7-11 years of age, 12-15 years of age and 16-18 years of age. Clinical examination showed 16.5% occurre...
