    Abstract:
    INTRODUCTION: Although omega (n)-3 long-chain polyunsaturated fatty acids (LCPUFA), particularly docosahexaenoic acid (DHA), intakes are important during infancy, the optimal method of increasing infant status remains unclear. We hypothesized that high-dose infant fish oil supplementation would have greater relative effects upon n-3 LCPUFA status at six months of age than breast milk fatty acids. PATIENTS AND METHODS: Infants (n=420) were supplemented daily from birth to six months with fish oil or placebo. In a subset of infants, LCPUFA levels were measured in cord blood, breast milk and in infant blood at 6 months. RESULTS: DHA levels increased in the fish oil group relative to placebo (p<05). Breast milk DHA was the strongest predictor of infant erythrocyte DHA levels (p=<001). This remained significant after adjustment for cord blood DHA, supplementation group and adherence. CONCLUSION: In this cohort, breast milk DHA was a greater determinant of infant erythrocyte n-3 LCPUFA status, than direct supplementation with fish oil.
