摘要： 目的 了解儿童在语言发育过程中特点及语言发育迟缓的情况,为儿童语言发育的正确评估指导提出科学依据。方法 选取来四川省妇幼保健院儿童保健科门诊就诊的1 016名18~36个月儿童作为研究对象,以《婴幼儿语言发育筛查量表》为调查工具进行测定。结果 男童在18~30月龄,语音表达和语音理解能力及整体语言发育水平均显著低于同年龄组女童(P<0.05),男童语言发育迟缓的发生率也显著高于女童,差异有统计学意义(P<0.05)。男女童语言的快速增长期都出现在24月后,但30~36月时,男女童语言发育比较差异无统计学意义(P>0.05)。结论 正确认识男女童发育上的差异,在语言发育早期重视男童的语言刺激及评估,对语言发育迟缓积极干预。
