We investigated the relationship between maternal docosahexaenoic acid (DHA) levels at birth and toddler free-play attention in the second year. Toddler free-play attention was assessed at 12 and 18 months, and maternal erythrocyte (red-blood cell; RBC) phospholipid DHA (percentage of total fatty acids) was measured from mothers at delivery. Overall, higher maternal DHA status at birth was associated with enhanced attentional functioning during the second year. Toddlers whose mothers had high DHA at birth exhibited more total looking and fewer episodes of inattention during free-play than did toddlers whose mothers had low DHA at birth. Analyses also provided further information on changes in attention during toddlerhood. These findings are consistent with evidence suggesting a link between DHA and cognitive development in infancy and early childhood.
我们研究了出生时母亲体内二十二碳六烯酸（DHA）水平与幼儿第二年自由玩耍时注意力之间的关系。在12个月和18个月时评估幼儿自由玩耍时的注意力，并在分娩时测量母亲红细胞（RBC）磷脂DHA（占总脂肪酸的百分比）。总体而言，出生时母亲较高的DHA状态与第二年注意力功能增强有关。与出生时母亲DHA水平较低的幼儿相比，出生时母亲DHA水平高的幼儿在自由玩耍时总的注视时间更长，注意力不集中的情况更少。分析还提供了有关幼儿期注意力变化的更多信息。这些发现与表明DHA与婴幼儿认知发展之间存在联系的证据一致。
