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: Evaluated whether the status of iodine nutrition influences the TSH concentration in a selected Chinese reference population according to the criteria proposed by National Academy of Clinical Biochemistry and regular thyroid ultrasonography to establish a new reference interval of TSH based on the wide variation of iodinenutrition in populations.

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: 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.

TL;DR: Median urinary iodine 100~200 μg/l may reflect the safe range of iodine intake levels, and serum thyrotropin/thyroglobulin ratio might be a better index of evaluating iodine status.
