In a previous study "N-3 Fatty Acid Requirements for Human Development" (C03-0242), pregnant women were randomly assigned to 400 mg/day DHA or placebo from 16 weeks of gestation until infant delivery. Blood DHA in gestation, and infant development to 18 months were assessed. This follow-up study will assess if maternal DHA in gestation has long-term influence on child development when assessed at 5 years and the impact of the child's own diet.
