To compare the lexical and grammatical development of a group of low risk preterm children with a group of full-term children at 10, 22, and 30 months of corrected age. In addition, the effect of possible determinant factors on linguistic development was investigated.
An initial group of 150 low-risk PR children (mean GA: 32.62) and 49 FT children (mean GA: 39.70) recruited at birth were assessed at 10, 22, and 30 months of age. Communicative and linguistic abilities were measured at these three points in time through the CDI. Cognitive development and quality of family environment of the children, among other variables, were also assessed at 22 months of age. Hierarchical regression analyses were performed in order to test those factors which may contribute to prediction of language outcomes.
There was no significant delay in communicative, lexical or grammatical development of PR children. Even when comparisons were performed between fullterm and very preterm children, differences were not significant. Regression analyses indicate that gestures and early word comprehension predict very early word production development, but their effect disappears with time. The most important factors which predict language development at 30 months of age are previous cognitive scores and word production at 22 months of age. The results coming from group comparisons and from hierarchical regression analyses indicate that GA does not significantly affect language development from 10 to 30 months of age.
Low risk preterm toddlers do not seem to be delayed in their linguistic development.
比较一组低风险早产儿童与一组足月儿在矫正年龄10个月、22个月和30个月时的词汇和语法发展情况。此外，还研究了可能的决定因素对语言发展的影响。
对出生时招募的150名低风险早产儿童（平均胎龄：32.62）和49名足月儿（平均胎龄：39.70）在10个月、22个月和30个月时进行评估。在这三个时间点通过儿童语言发展量表（CDI）测量沟通和语言能力。还在22个月时评估了儿童的认知发展和家庭环境质量等其他变量。进行分层回归分析以检验那些可能有助于预测语言结果的因素。
早产儿童在沟通、词汇或语法发展方面没有明显延迟。即使在足月儿和极早产儿童之间进行比较，差异也不显著。回归分析表明，手势和早期词汇理解可预测早期词汇产出发展，但随着时间推移其影响消失。在30个月时预测语言发展的最重要因素是之前的认知得分和22个月时的词汇产出。组间比较和分层回归分析的结果表明，胎龄在10至30个月时对语言发展没有显著影响。
低风险早产幼儿的语言发展似乎没有延迟。
