Early dietary long-chain n-3PUFA (n-3LCPUFA) may affect brain development. We investigated if fish oil supplementation of lactating mothers affected socioemotional wellbeing in adolescents in a potentially gender-specific manner. At age 13, we invited 92 children of mothers who completed a randomized trial with 1.5 g/d n-3 LCPUFA or olive oil during the first 4 months of lactation and 48 children of mothers with a high habitual fish intake. Children and parents answered validated questionnaires regarding socioemotional wellbeing and physical activity was monitored by ActiGraph for 7 days. Participation rate was 71%. Univariate correlations between children's and parents’ ratings on the individual scales were moderate-strong, but correlations across questionnaires indicated that parents might base their ratings on proxy markers. We found no group differences in self-rated socioemotional outcomes or physical activity. Although the study was small, it was the first follow-up on effects of perinatal n-3LCPUFA supply on socioemotional wellbeing in adolescence.
