Maternal Docosahexaenoic Acid Exposure Needed to Achieve Maternal-Newborn EQ.

ABSTRACT: Achieving maternal docosahexaenoic acid (DHA) status equal to or greater than the infant's DHA status at delivery is known as maternal-newborn DHA equilibrium (EQ) and is thought to be important for optimizing newborn DHA status throughout infancy. The objective of this study was to determine the daily DHA intake during pregnancy most likely to result in EQ. The participants (n = 1145) were from two randomized control trials of DHA supplementation in pregnancy. DHA intake was estimated using an abbreviated food frequency questionnaire. Total DHA exposure during pregnancy was calculated as a weighted average of the estimated DHA intake throughout pregnancy and the randomized DHA dose (200, 800, 1000 mg). Red blood cell DHA was measured from maternal and cord blood plasma at delivery
