Summary:
In infants born to mothers supplemented with DHA during pregnancy, prenatal DHA supplementation at 800 mg daily significantly improved markers of visual attention and showed faster visual learning compared to a lower dose (200 mg daily) and placebo groups, though it was associated with no reported adverse effects.
| PICO | Description |
|---|---|
| Population | Infants at 4 and 6 months of age born to mothers who participated in a prenatal DHA supplementation clinical trial. |
| Intervention | Daily prenatal supplementation with 800 mg of docosahexaenoic acid (DHA). |
| Comparison | Daily prenatal supplementation with 200 mg DHA or placebo. |
| Outcome | Infants whose mothers received 800 mg/day of DHA exhibited shorter look durations (indicative of enhanced visual learning) and a more mature pattern of heart rate-defined attention. No improvements were seen in the gap-overlap task, and heart rate measures did not differ by group. No adverse effects were reported. |
