This Finnish study compared language and reading abilities between schoolchildren born at a very low gestational age (VLGA) of <32 weeks and at term and analysed any associations between antenatal and neonatal risk factors and language skills in the VLGA group.
We prospectively followed 76 children born at a VLGA and 50 children born at term when they reached a mean age of 9.0 (8.1-10.0) years. They attended mainstream schools and had no severe neurosensory disabilities. Receptive language ability, rapid naming and word reading were evaluated using standardised tests.
Children in the VLGA group had lower scores for receptive language abilities (median 55.0 vs. 57.0, p = 0.01) and word reading (mean 4.4 vs. 5.1, p = 0.03) than the children in the term group. In the VLGA group, foetal growth restriction was associated with lower scores for rapid naming, early intraventricular haemorrhage was associated with poor word reading and respiratory distress syndrome was associated with poor rapid naming (p < 0.05).
Schoolchildren born at a VLGA had more difficulties with receptive language abilities and word reading than children born at term. Foetal growth restriction and early neonatal morbidities were associated with language difficulties.
这项芬兰的研究比较了孕周<32周的极低出生体重儿（VLGA）与足月儿的语言和阅读能力，并分析了VLGA组产前和新生儿危险因素与语言技能之间的关联。
我们前瞻性地追踪了76名VLGA出生的儿童和50名足月儿，当他们平均年龄达到9.0（8.1 - 10.0）岁时。他们就读于主流学校，且没有严重的神经感觉障碍。使用标准化测试评估接受性语言能力、快速命名和单词阅读。
VLGA组儿童的接受性语言能力得分（中位数55.0对57.0，p = 0.01）和单词阅读得分（平均4.4对5.1，p = 0.03）低于足月儿组。在VLGA组中，胎儿生长受限与快速命名得分较低相关，早期脑室内出血与单词阅读能力差相关，呼吸窘迫综合征与快速命名能力差相关（p < 0.05）。
VLGA出生的学龄儿童在接受性语言能力和单词阅读方面比足月儿有更多困难。胎儿生长受限和早期新生儿疾病与语言困难有关。
