Fish oil-supplementation from 9 to 12 months of age affects infant attention in a free-play test and is related to change in blood pressure.

INTRODUCTION: This intervention examined whether fish-oil-supplementation in late infancy modifies free-play test scores and if this is related to blood pressure (BP) and mean RR interval. PATIENTS AND METHODS: 83 Danish 9-month-old infants were randomized to ±fish oil (FO) (3.4±1.1mL/d) for 3months and 61 of these completed the free-play-test before and after the intervention.
RESULTS: Most of the free-play scores changed during the intervention, but the intervention affected only the number of looks away from the toy, which was increased in +FO and decreased in -FO (p=0.037). The increased numbers of looks away were associated with an increase in erythrocyte eicosapentaenoic acid (r=0.401, p=0.017, n=35) and were also associated with a decrease in systolic-BP (r=-0.511, p<0.001, n=52).
CONCLUSIONS: The results indicate that n-3 fatty acid intake also in late infancy can influence brain development and that the cognitive and cardiovascular effects may be related.
