expressive language of pre-term children.
to compare the expressive vocabulary of two year-old children born prematurely, to that of those born at term.
the study sample was composed by 118 speech-language assessment protocols, divided in two groups: the pre-term group (PTG) composed by 58 underweight premature children followed by a multi-professional team at the Casa do Prematuro (House of Premature Children) at Unifesp, and the full-term group (FTG) composed by 60 full-term born children. In order to evaluate the expressive language of these children, the Lave - Lista de Avaliação do Vocabulário Expressivo (Assessment List of the Expressive Vocabulary) was used. The Lave is an adaptation of the LDS - Language Development Survey - for the Brazilian Portuguese Language. The Lave investigates the expressive language and detects delays in oral language.
children born underweight and prematurely present a greater occurrence of expressive language delay, 27.6%. These pre-term children present significantly lower expressive vocabulary and phrasal extension than children of the same age born at full-term in all semantic categories. Family income proved to be positively associated to phrasal extension, as well as to gestational age and weight at birth; thus indicating the effect of these adverse conditions still during the third year of age. The audiological status was associated to word utterances in the PTG.
children born prematurely and underweight are at risk in terms of vocabulary development; this determines the need for speech-therapy intervention programs.
早产儿的表达性语言。
比较早产的两岁儿童与足月出生儿童的表达性词汇量。
研究样本由118份言语语言评估方案组成，分为两组：早产组（PTG），由58名低体重早产儿组成，由圣保罗联邦大学早产儿之家（Casa do Prematuro）的多专业团队跟踪；足月组（FTG），由60名足月出生的儿童组成。为了评估这些儿童的表达性语言，使用了Lave - Lista de Avaliação do Vocabulário Expressivo（表达性词汇评估清单）。Lave是对LDS - 语言发展调查 - 针对巴西葡萄牙语的改编。Lave调查表达性语言并检测口语延迟。
低体重早产出生的儿童出现表达性语言延迟的发生率更高，为27.6%。在所有语义类别中，这些早产儿童的表达性词汇量和短语扩展明显低于足月出生的同龄儿童。家庭收入被证明与短语扩展以及胎龄和出生体重呈正相关；因此表明这些不利条件在三岁时仍有影响。听力状况与早产组的单词发音有关。
早产和低体重出生的儿童在词汇发展方面存在风险；这决定了需要言语治疗干预计划。
