Background: Animal studies indicate that maternal prenatal choline supplementation leads to permanent enhancement of attention and spatial memory abilities in offspring, whereas dietary choline restriction during pregnancy impairs cognitive function in offspring. The association between gestational choline concentrations and neurodevelopmental outcome in humans has not been studied. Objective: Our objective was to assess the relation between maternal and cord blood choline concentrations and child intelligence quotient (IQ) scores at 5 y of age. Design: With data and samples from a prospective study (n = 404 maternal-child pairs), serum concentrations of free and total choline were measured in maternal serum at 4 gestational age intervals (16–18 wk, 24–26 wk, 30–32 wk, and 36–38 wk) and in cord blood. Child IQ at 5 y of age was assessed with the Wechsler Preschool and Primary Scale of Intelligence-Revised. Multiple regression techniques were used to estimate the relation between choline concentrations and Full Scale IQ, Verbal and Performance IQ, and subscales that assess spatial relation and memory ability while adjusting for other factors that affect IQ. Results: There was no effect at gestational ages 16–18 wk, 24–26 wk, 30–32 wk, and 36–38 wk or in cord blood of serum concentrations of free or total choline on Full Scale child IQ or on selected scales related to visuospatial processing and memory. Conclusion: Gestational and newborn choline concentrations in the physiologic range showed no correlation with childhood intelligence.
