Language development at 3 years of pre-term children born below 1000 g birth weight was compared with full-term controls matched for social background. The pre-term group used less complex expressive language and showed lower receptive understanding, auditory memory and verbal reasoning. Language outcome was related to intraventricular haemorrhage but not to global indication of postnatal illness such as number of days on the ventilator. Average verbal intelligence in environmentally low risk, extremely low birth weight children is an insufficient indicator of complex language functioning.
将出生体重低于1000克的早产儿3岁时的语言发展情况与社会背景相匹配的足月儿对照组进行了比较。早产组使用的表达性语言较不复杂，在接受性理解、听觉记忆和言语推理方面表现较低。语言结果与脑室内出血有关，但与出生后疾病的整体指标（如使用呼吸机的天数）无关。在环境低风险的极低出生体重儿童中，平均言语智力并不能充分反映复杂的语言功能。
