Abstract

Objective Our purpose was to evaluate the association between fetal iron status and mental and psychomotor development at 5 years of age.Study design We evaluated the association of fetal iron status (umbilical cord serum ferritin concentrations) with test scores of mental and psychomotor development of 278 children. Six tests were given, including full-scale intelligence quotient (FSIQ), language ability, fine- and gross-motor skills, attention, and tractability.Results Compared with children with cord ferritin in the 2 median quartiles, those in the lowest quartile scored lower on every test and had significantly worse language ability, fine-motor skills, and tractability. They were also 4.8-fold more likely to score poorly in fine-motor skills and 2.7-fold more likely to have poor tractability than children in the median quartiles. FSIQ in the highest quartile was slightly, but not significantly, lower than the median quartiles, but the odds ratio for having a FSIQ score of less than 70 for children in the highest quartile was 3.3 (95% CI 1.2-9.1).Conclusion Poor iron status (low ferritin) in utero appears to be associated with diminished performance in certain mental and psychomotor tests. The reason for the association between high ferritin concentrations and low FSIQ scores is unknown.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • High iron intake from supplements or fortified products is known to be toxic, has been linked to negative health effects such as adverse neurodevelopmental outcomes, and may be particularly harmful for some genetically susceptible people.

    “very high iron intake in supplemental or forti fi ed forms is known to be toxic and has been associated with negative health impacts, including adverse neurodevelopmental outcomes, and could be especially harmful for certain genetically susceptible individuals (42, 45).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
