TL;DR: More than adequate or excessive iodine intake may lead to hypothyroidism and autoimmune thyroiditis in cohorts from three regions with different levels of iodine intake.

TL;DR: Subclinical hyperthyroidism is more prevalent in the iodine deficient area than in the severe iodine excessive area, and in the area with mild iodine deficiency, the introduction of universal salt iodization may not be accompanied by an increased incidence of hyper thyroidroidism.

TL;DR: Iodine supplementation may not induce an increase in hyperthyroidism in a previously mildly iodine-deficient population, suggesting that excessive iodine intake may not be an environmental factor involved in the occurrence of autoimmune hyper thyroidroidism.

TL;DR: It was concluded that positive TPOAb was of value for predicting the occurrence and severity of PPT, and a high iodine intake was a risk factor triggering PPT.

TL;DR: The increase of iodine intake may increase the risk for schoolchildren of subclinical hypothyroidism, and no obvious effect of excess iodine was found on mental development of schoolchildren.
