Infants were followed longitudinally to document the relationship between docosahexaenoic acid (DHA) levels and the development of attention. Erythrocyte (red-blood cell; RBC) phospholipid DHA (percentage of total fatty acids) was measured from infants and mothers at delivery. Infants were assessed in infant-control habituation at 4, 6, and 8 months augmented with psychophysiological measures, and on free-play attention and distractibility paradigms at 12 and 18 months. Infants whose mothers had high DHA at birth showed an accelerated decline in looking over the 1st year and increases in examining during single-object exploration and less distractibility in the 2nd year. These findings are consistent with evidence suggesting a link between DHA and cognitive development in infancy.
对婴儿进行纵向跟踪，以记录二十二碳六烯酸（DHA）水平与注意力发展之间的关系。在分娩时测量婴儿和母亲红细胞（RBC）磷脂中的DHA（占总脂肪酸的百分比）。在4、6和8个月时，通过心理生理测量对婴儿进行婴儿对照习惯化评估，并在12和18个月时进行自由玩耍注意力和注意力分散范式评估。母亲在婴儿出生时DHA水平高的婴儿，在第一年的注视时间加速下降，在单物体探索期间的检查次数增加，在第二年注意力分散较少。这些发现与表明DHA与婴儿认知发展之间存在联系的证据一致。
