Аннотация:This study investigated maternal prenatal docosahexaenoic acid ( DHA ) intake and infant cognitive development at 22 months. Estimates for second‐ and third‐trimester maternal DHA intake levels were obtained using a comprehensive Food Frequency Questionnaire. Infants ( n = 67) were assessed at 22 months on a novel object search task. Mothers' DHA intake levels were divided into high or low groups, with analyses revealing a significant positive effect of third‐trimester DHA on object search task performance. The third trimester appears to be a critical time for ensuring adequate maternal DHA levels to facilitate optimum cognitive development in late infancy.
