Abstract

Background Cumulative evidence shows that low maternal folate levels during pregnancy are associated with offspring neuropsychiatric disorders even in the absence of neural tube defects. However, the relationship between prenatal exposure to folate and brain development in late childhood has been rarely investigated. Methods In 2095 children from a prospective population-based cohort in Rotterdam, the Netherlands, we examined the association of maternal folate levels during pregnancy with downstream brain development in offspring. Maternal folate concentrations were measured from venous blood in early gestation. Child structural neuroimaging data were measured at age 9-11 years. In addition, measures of child head circumference using fetal ultrasound in the third trimester and total brain volume using magnetic resonance imaging at age 6-8 years were used for analyses with repeated assessments of brain development. Results Maternal folate deficiency (i.e., <7 nmol/L) during pregnancy was associated with smaller total brain volume (B = -18.7 cm 3, 95% CI -37.2 to -0.2) and smaller cerebral white matter (B = -7.2 cm 3, 95% CI -11.8 to -2.6) in children aged 9-11 years. No differences in cortical thickness or surface area were observed. Analysis of the repeated brain assessments showed that children exposed to deficient folate concentrations in utero had persistently smaller brains compared to controls from the third trimester to childhood (β = -0.4, 95% CI -0.6 to -0.1). Conclusions Low maternal folate levels during pregnancy are associated with altered offspring brain development in childhood, suggesting the importance of essential folate concentrations in early pregnancy.

  • Emerging data demonstrate an association between inadequate maternal folate status during gestation and aberrant neurodevelopmental trajectories in offspring, with implications extending to long-term neuropsychiatric outcomes.

    “Emerging data from contemporary investigations demonstrate an association between inadequate maternal folate status during gestation and aberrant neurodevelopmental trajectories in offspring, with implications extending to long-term neuropsychiatric outcomes.”
  • Offspring exposed to suboptimal intrauterine folate environments exhibit distinctive neuroanatomical alterations, including diminished cerebral white matter and subcortical gray matter volumes, increased cortical thickness in left frontal regions, and reduced surface area bilaterally across frontal and temporal cortices.

  • Adequate maternal folate status protects against neural tube defects and supports proper brain development, while deficiency is associated with persistent alterations in offspring neurodevelopment and an increased risk of obesity and insulin resistance later in life.

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.
