Thus, variations in maternal ARA or DHA status may modify neurocognitive development. We investigated the relationship between maternal ARA and DHA status in early (11\u00b77 weeks) or late (34\u00b75 weeks) pregnancy on neurocognitive function at the age of 4 years or 6\u20137 years in 724 mother\u2013child pairs from the Southampton Women\u2019s Survey cohort. Plasma phosphatidylcholine fatty acid composition was measured in early and late pregnancy. ARA concentration in early pregnancy predicted 13 % of the variation in ARA concentration in late pregnancy (<jats:italic>\u03b2<\/jats:italic>=0\u00b736,<jats:italic>P<\/jats:italic>&lt;0\u00b7001). DHA concentration in early pregnancy predicted 21 % of the variation in DHA concentration in late pregnancy (<jats:italic>\u03b2<\/jats:italic>=0\u00b746,<jats:italic>P<\/jats:italic>&lt;0\u00b7001). Children\u2019s cognitive function at the age of 4 years was assessed by the Wechsler Preschool and Primary Scale of Intelligence and at the age of 6\u20137 years by the Wechsler Abbreviated Scale of Intelligence. Executive function at the age of 6\u20137 years was assessed using elements of the Cambridge Neuropsychological Test Automated Battery. Neither DHA nor ARA concentrations in early or late pregnancy were associated significantly with neurocognitive function in children at the age of 4 years or the age of 6\u20137 years. These findings suggest that ARA and DHA status during pregnancy in the range found in this cohort are unlikely to have major influences on neurocognitive function in healthy children.<\/jats:p>","DOI":"10.1017\/s0007114518000806","type":"journal-article","created":{"date-parts":[[2018,5,8]],"date-time":"2018-05-08T03:10:48Z","timestamp":1525749048000},"page":"1400-1407","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":10,"title":["Arachidonic
