TL;DR: To examine the relationship between specific thyroid abnormalities in women during pregnancy and the subsequent neuropsychological development of their offspring.

TL;DR: The prevalence and spectrum of thyroid disorders has increased, reflecting possible adverse effects of increased iodine intake, and the prevalence of clinical hypothyroidism, subclinical hypothyroxine, and positive thyroid antibodies was significantly higher in MTAII cities than it was in AII cities.

TL;DR: The upper limit of iodine intake during early pregnancy in an iodine-sufficient region should not exceed UIC 250 μg/L, because this is associated with a significantly high risk of subclinical hypothyroidism, and a UIC of 500 μg/ L should not be exceeded, as it is associatedWith a significantlyHigh risk of isolated hypothyroxinemia.

TL;DR: Women with a combination of SCH and TAI were found to have the highest risk and earlier gestational ages of miscarriage between four and eight gestational weeks, which is at an increased risk of miscarriage in women at low risk for thyroid dysfunction.

TL;DR: The reference range for nonpregnant women can be used for the assessment of pregnant women at 4 to 6 weeks of gestation and the upper limit of serum TSH in the first trimester was much higher than 2.5 mIU/L in Chinese pregnant women.
