我们研究了极早产儿（妊娠30周的千分之一货币符号）在学龄早期是否有独立于智商和处理速度的执行功能（EF）障碍，以及人口统计学和新生儿风险因素是否与EF障碍相关。50名儿童的连续样本（27名男孩和23名女孩）早产（平均年龄= 5.9岁，SD = 0.4，平均胎龄= 28.0周，SD = 1.4）与50例年龄匹配的足月对照样本进行比较。（23名女孩和27名男孩，平均年龄= 6.0岁，SD = 0.6）关于在综合EF成套测验上的表现，评估抑制、工作记忆、转换、言语流畅性和概念生成的领域。早产儿组表现出较差的性能相比，所有EF域的控制，即使在偏出智商的影响。处理速度与EF略有相关。人口统计学和新生儿危险因素分析显示，母亲的文化程度和孕龄与EF有关。这项研究增加了新兴的文献显示，非常早产与EF损伤。
We examined whether very preterm (a parts per thousand currency sign30 weeks gestation) children at early school age have impairments in executive function (EF) independent of IQ and processing speed, and whether demographic and neonatal risk factors were associated with EF impairments. A consecutive sample of 50 children (27 boys and 23 girls) born very preterm (mean age = 5.9 years, SD = 0.4, mean gestational age = 28.0 weeks, SD = 1.4) was compared to a sample of 50 age-matched full-term controls (23 girls and 27 boys, mean age = 6.0 years, SD = 0.6) with respect to performance on a comprehensive EF battery, assessing the domains of inhibition, working memory, switching, verbal fluency, and concept generation. The very preterm group demonstrated poor performance compared to the controls on all EF domains, even after partialing out the effects of IQ. Processing speed was marginally related to EF. Analyses with demographic and neonatal risk factors showed maternal education and gestational age to be related to EF. This study adds to the emerging body of literature showing that very preterm birth is associated with EF impairments.
