Prenatal DHA Supplementation and Infant Attention
BackgroundâResults of randomized trials on the effects of prenatal docosahexaenoic acid
(DHA) on infant cognition are mixed, but most trials have used global standardized outcomes,
which may not be sensitive to effects of DHA on specific cognitive domains.
MethodsâWomen were randomized to 600 mg/d DHA or a placebo for the last two trimesters of
pregnancy. Infants of these mothers were then followed on tests of visual habituation at 4, 6, and 9
months of age.
ResultsâDHA supplementation did not affect look duration or habituation parameters but
infants of supplemented mothers maintained high levels of sustained attention (SA) across the first
year; SA declined for the placebo group. The supplemented group also showed significantly
reduced attrition on habituation tasks, especially at 6 and 9 months.
ConclusionâThe findings support with the suggestion that prenatal DHA may positively affect
infantsâ attention and regulation of state
