Abstract: Object To investigate the developmental characteristic in children with language developmental delay, know their developmental trajectory and provide reference for clinic and interference. Methods A total of 253 children (including boy 198 cases, girl 55 cases)were included, who were developmental language delay under five years old .Gesell test was used to evaluate children neurodevelopment. Results 1)As the children with developmental language delay getting older, the proportion of the only language problem was decreasing, 1～2 years old 38.46%, 2～3 years old 15.97%, 3～4 years old 10.96% and 4~5 years old none.2)After 2 years old, the DQ of each domain was significant declined (P<0.001), the DQ of language was the lowest. Conclusion Language is a sensitive indicator of different developmental problems, after 2 years old, language problems maybe the presence of other developmental disorders.

摘要： 目的 研究语言发育迟缓儿童在不同年龄阶段的发育特征, 从而了解其发育的轨迹, 为临床诊治和干预提供一定的依据。方法 以2010年8月-2011年2月在上海儿童医学中心发育行为儿科因语言发育迟缓就诊的5岁以下儿童为研究对象, 共253例, 其中男198例, 女55例。用Gesell婴幼儿发育量表进行发育评估。结果 1)随年龄增长, 以语言发育迟缓为主诉的儿童其单纯性语言问题的比例逐渐下降, 1～2岁儿童中38.46%表现为单纯性语言问题, 2～3岁降为15.97%, 3～4岁为10.96%, 4～5岁则没有单纯的语言问题。2)随年龄增长, 各能区的发育商显著下降(P＜0.001), 2岁后各能区发育商均为异常, 言语能的发育商则为各能区最低。结论 语言是不同发育问题的一个敏感指标, 2岁后的语言问题更多是其他发育障碍的表现之一, 而非单纯的语言问题。
