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: An association between ID and isolated hypothyroxinemia was found in both pregnant and nonpregnant childbearing-aged women, independent of the effects of iodine and thyroid autoimmunity, and it is speculated that ID may be a pathogenic factor for hypothyoxinemia, even in pregnant women during the first trimester.

TL;DR: High BMI during early pregnancy may be an indicator of maternal thyroid dysfunction; for Asian women whose BMI > 24 kg/m2 and who are within 8 weeks of pregnancy, thyroid functions should be assessed especially.

TL;DR: T careful follow-up of SCH pregnant women with levothyroxine (LT4) should be taken, and thyroid function should be tested every month until the end of pregnancy, because a small part of patients require adjust therapy also during the second and third trimester.

TL;DR: No significant difference was found between a SLRI and a CSRI, even in a stringent self-sequential longitudinal reference interval of thyroid function in pregnant women.
