Abstract

Objectives Docosahexaenoic (DHA) and arachidonic (AA) acids are important for neurodevelopment. We investigated the relation between erythrocyte (RBC) DHA and AA contents and neurological development, by assessment of General Movements (GMs), in populations with substantial differences in fish intakes. Methods We included 3-month-old breastfed infants of three Tanzanian tribes: Maasai (low fish, n = 5), Pare (intermediate fish, n = 32), and Sengerema (high fish, n = 60); and a Dutch population (low–intermediate, fish, n = 15). GMs were assessed by motor optimality score (MOS) and the number of observed movement patterns (OMP; an MOS sub-score). RBC-DHA and AA contents were determined by capillary gas chromatography. Results We found no between-population differences in MOS. OMP of Sengerema infants (high fish) was higher than OMP of Dutch infants (low–intermediate fish). MOS related to age. OMP related positively to infant age (P < 0.001) and RBC-DHA (P = 0.015), and was unrelated to ethnicity and RBC-AA. Discussion The positive relation between RBC-DHA and the number of observed movement patterns of 3-month old infants might reflect the connection of DHA with motor development.

Abstract

Little is known about the interrelationships between maternal and infant erythrocyte-DHA, milk-DHA and maternal adipose tissue (AT)-DHA contents. We studied these relationships in four tribes in Tanzania (Maasai, Pare, Sengerema and Ukerewe) differing in their lifetime intakes of fish. Cross-sectional samples were collected at delivery and after 3 d and 3 months of exclusive breast-feeding. We found that intra-uterine biomagnification is a sign of low maternal DHA status, that genuine biomagnification occurs during lactation, that lactating mothers with low DHA status cannot augment their infants' DHA status, and that lactating mothers lose DHA independent of their DHA status. A maternal erythrocyte-DHA content of 8 wt% was found to correspond with a mature milk-DHA content of 1·0 wt% and with subcutaneous and abdominal (omentum) AT-DHA contents of about 0·39 and 0·52 wt%, respectively. Consequently, 1 wt% DHA might be a target for Western human milk and infant formula that has milk arachidonic acid, EPA and linoleic acid contents of 0·55, 0·22 and 9·32 wt%, respectively. With increasing DHA status, the erythrocyte-DHA content reaches a plateau of about 9 wt%, and it plateaus more readily than milk-DHA and AT-DHA contents. Compared with the average Tanzanian-Ukerewe woman, the average US woman has four times lower AT-DHA content (0·4 v. 0·1 wt%) and five times lower mature milk-DHA output (301 v. 60 mg/d), which contrasts with her estimated 1·8–2·6 times lower mobilisable AT-DHA content (19 v. 35–50 g).
