Infant thyroid hypofunction classification
Infant thyroid hypofunction classification. Study-specific scope and measurement methods are recorded with each claim.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
Infant thyroid hypofunction classifications were less frequent with indirect maternal supplementation (P=0.023), although infant TSH and T4 concentrations did not differ significantly between groups over time (P=0.597 and 0.184).

- Term infants ≤ 8 weeks; indirect arm 121 pairs: mother 400 mg iodine as oral iodized poppyseed oil, infant placebo; direct arm 118 pairs: infant about 100 mg iodine from half a 200 mg oil capsule, mother placebo; follow-up 3, 6, 9 months.
- limitations
- Both arms received active iodine somewhere in the pair; there was no wholly untreated arm. Breastfeeding and baseline deficiency contextualize the result; measured iodine status is not a child cognitive outcome. Actual infant study dose was about 100 mg, not the 200 mg guideline discussed elsewhere in the paper. No serious adverse events were reported; this does not establish safety for other infant doses, preparations or settings.
