目的 探讨视屏暴露环境与儿童语言发育迟缓的相关性.方法 设计问卷调查语言发育迟缓儿童的视屏暴露信息及家庭环境信息,通过多元线性回归分析视屏暴露因素对儿童语言发育的影响.结果 134例16-48月龄的语言发育迟缓儿童,视屏暴露的起始月龄为(11.57±5.32)月,儿童每日视屏暴露总时长达(118.79±99.89)min.多元线性回归分析发现,视屏暴露起始月龄越小(t=3.743,P<0.001),每日视屏暴露总时间越长(t=-3.547,P=0.001),母子间对话时间越短(t=2.877,P=0.005),儿童的语言DQ值越低.结论 过早、过久的视屏暴露及母子间缺乏对话交流,是儿童语言发育迟缓的重要危险因素.减少视屏暴露,并增加亲子对话交流,有助于预防语言发育迟缓的发生.
