The present study analyzed the links between prematurity, attention, and global cognitive performance in infancy and early childhood. At 7 months, focused attention (FA) was examined with an object examination task in 93 preterm infants (39 of them born extremely/very preterm, 54 born moderately/late preterm, and 38 infants born full-term). Global cognition was assessed at 7 and 24 months with the Bayley-II cognitive scale. Groups did not differ with respect to global cognitive performance but FA of infants born extremely/very preterm was significantly lower than in infants born moderately/late preterm. FA correlated significantly with both prematurity and cognitive performance at 7 months of age but not with global cognition in childhood. Findings point to a subtle adverse effect of prematurity on early attention and reveal evidence for the mediating role of FA on the effect of prematurity on cognition.
本研究分析了早产、注意力与婴幼儿期整体认知表现之间的联系。在7个月时，通过一项物体检查任务对93名早产儿（其中39名极早早产/非常早产儿，54名中度/晚期早产儿，38名足月儿）的集中注意力（FA）进行了检查。在7个月和24个月时，使用贝利-II认知量表评估整体认知。各组在整体认知表现方面没有差异，但极早早产/非常早产儿的FA显著低于中度/晚期早产儿。FA在7个月大时与早产和认知表现均显著相关，但与儿童期的整体认知无关。研究结果表明早产对早期注意力有微妙的不利影响，并揭示了FA在早产对认知影响中的中介作用的证据。
