UNASSIGNED: In this investigation we compare language development [use of words, sentence complexity and mean length of the three longest utterances (MLU3)] of three groups of Chilean children at 24 months of age (corrected age for preterm children). The first group was composed of 42 healthy full-term children (Full term group: FT), the second group of 60 preterm children born below 32 gestational weeks without medical complications (low risk preterm group: LRPT), and the third group was composed of 64 children below 32 gestational weeks who had medical complications (High risk preterm group: HRPT). The three groups were similar in terms of gender distribution, maternal education, and socio-economic environment. The instrument used to assess language was the Communicative Development Inventories (CDI). In addition, the Ages and Stages Questionnaire-3 (ASQ-3) was also used to assess other developmental dimensions.
UNASSIGNED: The results indicate that HRPT and LRPT children obtained significantly lower results than the FT group in the three language measures obtained through the CDI. No significant differences were observed between the HRPT and the LRPT groups, although the HRPT obtained the lowest results in the three CDI measures. The results obtained through the administration of the ASQ-3 confirm the delay of both preterm groups in communicative development when compared to the FT group. No significant differences between the FT and the PT groups were observed in gross motor, fine motor and problem solving dimensions of the ASQ-3. The LRPT group obtained results that were significantly higher than those of the FT group and the HRPT group in gross motor development.
UNASSIGNED: These results seem to indicate that the area of language development is particularly influenced by very or extremely low gestational age.
■在这项调查中,我们比较了语言发展[单词的使用,三组24个月大的智利儿童的句子复杂性和三个最长话语的平均长度(MLU3)](早产儿的校正年龄)。第一组由42名健康的足月儿童组成(足月组:FT),第二组60名出生在32孕周以下且无医疗并发症的早产儿(低风险早产组:LRPT),第三组由64名32孕周以下有内科并发症的儿童组成(高危早产组:HRPT)。三组在性别分布方面相似,母亲教育,和社会经济环境。用于评估语言的工具是交际开发清单(CDI)。此外,年龄和阶段问卷-3(ASQ-3)也用于评估其他发展维度。
■结果表明,在通过CDI获得的三种语言测量中,HRPT和LRPT儿童获得的结果明显低于FT组。HRPT和LRPT组之间没有观察到显著差异,尽管HRPT在三种CDI测量中获得的结果最低。通过施用ASQ-3获得的结果证实了与FT组相比,两个早产组在沟通发展方面的延迟。FT组和PT组的粗大运动无显著差异,ASQ-3的精细电机和解决问题的尺寸。LRPT组取得的成果在粗大运动发育方面明显高于FT组和HRPT组。
■这些结果似乎表明,语言发育的区域尤其受到极低胎龄或极低胎龄的影响。
