Iodine Deficiency in Pregnancy: The Effect on …
Severe iodine deficiency during pregnancy is a known cause of cretinism and mental retardation. At present, there are limited data on the cognitive deficits of children born to mothers who are moderately iodine deficient in pregnancy. There is a need for well designed clinical trials investigating whether routine iodine supplementation of ...

Iodine Deficiency
In mild or moderate iodine deficiency, the thyroid gland, influenced by thyroid-stimulating hormone (TSH), hypertrophies to concentrate iodide in itself, resulting in colloid goiter. Usually, patients remain euthyroid; however, severe iodine deficiency in adults may cause hypothyroidism (endemic myxedema). It can decrease fertility and increase ...

This can cause many problems. In pregnant women, severe iodine deficiency can permanently harm the fetus by causing stunted growth, intellectual disability, and delayed sexual development. Less severe iodine deficiency can cause lower-than-average IQ in infants and children and decrease adults' ability to work and think clearly.

Iodine supplementation (200 μg/day) reduced the proportion of pregnant women with severe iodine deficiency (37.4% to 18.0%, p = 0.0002). The median UIC increased from 67.6 µg/L to 106.8 µg/L but remained below the recommended target level (>150 µg/L) for pregnant women. In conclusion, iodine supplementation in pregnant …

Iodine Deficiency Workup
Severe iodine deficiency results in impaired thyroid hormone synthesis and/or thyroid enlargement (goiter). Population effects of severe iodine deficiency, termed iodine deficiency disorders (IDDs), include endemic goiter, hypothyroidism, cretinism, decreased fertility rate, increased infant mortality, and mental retardation.

The thyroid clearance of iodine is around 10–20 mL/min, but it depends on chronic iodine consumption, ranging from 3 mL/min in cases of chronic overexposure to large amounts of iodine (more than 500 μg/day), to 100 mL/min in cases of severe iodine deficiency . Iodide uptake in the thyroid gland occurs through a specific carrier, the NIS.

In nearly all regions affected by iodine deficiency, salt iodization is the most cost-effective way of delivering iodine (5, 8, 9). Global population coverage with iodized salt increased from 20% in 1990 to approximately 70% in 2013 (3). The annual costs of salt iodization are estimated to be US$0.02–0.05 per child covered, with the costs per ...
