This study determined whether cognitive outcomes differed between very preterm (VPT) and extremely preterm (EPT) children who were monolingual or multilingual when they reached the corrected ages of two and five years.
The data were collected at the Emma Children's Hospital, Amsterdam, The Netherlands, as part of our national neonatal follow-up programme and comprised 325 VPT/EPT children born between January 1, 2007 and January 1, 2012. The study used the Third Editions of the Bayley Scales of Infant and Toddler Development and the Wechsler Preschool and Primary Scale of Intelligence.
We compared 234 monolingual children, 65 multilingual children who spoke Dutch and at least one foreign language at home and 26 multilingual children who didn't speak Dutch at home. The best performers on the cognitive scale at two years of age and the verbal subscales at five years of age were the monolingual children, followed by the children who spoke Dutch and at least one foreign language at home, then the children who only spoke foreign languages at home.
In our study cohort from The Netherlands, multilingualism lowered the cognitive and verbal outcomes of VPT/EPT children at the corrected ages of two and five years.
本研究旨在确定当极低出生体重儿（VLBWI）和极早产儿（ELBWI）达到校正年龄 2 岁和 5 岁时，他们是单语还是双语，其认知结果是否存在差异。
该数据来自荷兰阿姆斯特丹艾玛儿童医院，是我们国家新生儿随访计划的一部分，包括 2007 年 1 月 1 日至 2012 年 1 月 1 日期间出生的 325 名 VLBWI/ELBWI 儿童。研究使用了第三版贝利婴幼儿发育量表和韦氏学前和小学智力量表。
我们比较了 234 名单语儿童、65 名在家中讲荷兰语和至少一种外语的双语儿童以及 26 名在家中不讲荷兰语的双语儿童。在 2 岁时认知量表和 5 岁时言语分量表上表现最好的是单语儿童，其次是在家中讲荷兰语和至少一种外语的儿童，然后是只在家中讲外语的儿童。
在我们来自荷兰的研究队列中，双语环境降低了 VLBWI/ELBWI 儿童在校正年龄 2 岁和 5 岁时的认知和言语能力。
