Kim Michaelsen. Maternal fish oil supplementation in lactation: effect on developmental outcome in breast-fed infants. Abstract -Docosahexaenoic acid (DHA) accumulates in the brain during the 1st and 2nd years of life. The objective of this study was to see if an increased content of DHA in breast-milk via maternal fish oil (FO)-supplementation affects mental development in term infants. one hundred twenty-two Danish mothers with a habitual fish intake below the population median were

Fifty-three mothers with habitual fish intake in the highest quartile were included as reference group. The effect of the resulting increase in infant DHA-intake and RBC-DHA level was assessed on problem solving ability at nine months and language at one and two years of age. Infants in the three groups performed equally well on the problem test and no association was observed between problem solving and erythrocyte-DHA at four months. Passive vocabulary at one year was lower in the children of the FO-compared with the OOgroup (P < 0.05), but no differences were found at two years of age. Word comprehension at one year was inversely associated with erythrocyte-DHA at four months. The trial indicate a small effect of DHA levels in breast-milk on early language development of breast-fed infants. docosahexaenoic acid / breast-milk / infant development / long-chain n-3 fatty acid / optimal dietary intake Abbreviations: AA: arachidonic acid; CDI: communicative development inventory; DHA: docosahexaenoic acid; FO: fish oil; LCPUFA: long-chain polyunsaturated fatty acid; OO: olive oil; PUFA: polyunsaturated fatty acid; RBC: red blood cells. * Corresponding author: ll@kvl.dk Article published by EDP Sciences and available at http://www.edpsciences.org/rnd or http://dx.
