Abstract: Objective To explore the association between screen time and infant language delay,in order to provide evidence for the prevention of language delay in infants. Methods A randomized sampling method was used to select 112 infants aged 18 to 46 months diagnosed with language delay in Shanghai Children's Hospital as case group from November 2017 to August 2018,meantime 66 healthy children matched by gender and age were selected as control group. A self-designed questionnaire on infant language delay and screen time was used to conduct this survey. Results There were no statistically significant differences on children's age,parents' occupation and whether parents were only child or not(P>0.05),while parents of control group had older age and higher educational level(P<0.05). However,mothers in case group had spent more time with their children on weekdays than mothers in normal group(t=-2.281,P=0.020). And the average screen time in case group was significantly longer than that in control group(t=-3.224,P=0.002). The content of screen in children was mainly animation,but the proportion of normal children watching science films was slightly higher than that of case group(χ2=11.558,P=0.009). In terms of limiting the screen time and having a rest after screen time more than 30 minutes,parents of normal children performed better than that of case group(χ2=6.962,11.034, P<0.05). Parents in case group allowed their kids to use video products more frequently than parents in control group(χ2=11.752,P=0.003). Mothers from case group spent more total time and leisure time on screen than mothers from control group(t=-2.920,-2.145,P<0.05). After controlling for confounding factors,it was found that children's screen time was an important factor affecting language development. For every one hour increase in children's screen time,the language development quotient decreased by 1.626. Conclusions Screen time is an important factor affecting children's language development. It is suggested to limit children's screen time every day in the family and parents should set an example to increase face-to-face emotional communication opportunities,thereby promoting children's early development.

摘要: 探索儿童视屏时间对幼儿语言发育迟缓的影响,以期为儿童语言发育迟缓的预防提供依据。方法 采用随机抽样,选取2017年11月—2018 年8月于上海市儿童医院儿童保健科诊断为语言发育迟缓的112例18~46月龄儿童为病例组,以性别、年龄作为匹配因素,筛选同期正常体检的儿童66 例作为对照组,利用幼儿语言发育迟缓及视屏时间流行病学调查问卷对研究对象进行问卷调查。结果 两组儿童的年龄及父母的职业、双方是否是独生子女等方面的差异无统计学意义(P>0.05)。对照组儿童父母年龄偏大,文化程度相对较高,语言迟缓组儿童的母亲工作日与子女接触时间比正常儿童母亲长(t=-2.281,P=0.020)。语言迟缓儿童视屏时间相对正常儿童更久,差异有统计学意义(t=-3.224,P=0.002)。儿童视屏的内容以动画片为主,但对照组儿童观看科教片的比例稍高于病例组(χ2=11.558,P=0.009)。在每天限制视屏时间、观看30 min及以上休息方面,对照组儿童家长的执行比例高于病例组(χ2=6.962、11.034,P<0.05)。当儿童任性或状态不佳时,语言迟缓儿童家长经常允许儿童使用视屏产品的比较更高(χ2=11.752,P=0.003)。病例组儿童母亲的视屏总时间、闲暇时的视屏时间也高于对照组儿童母亲(t=-2.920、-2.145,P<0.05)。控制了混杂因素后发现儿童视屏时间是影响语言发育迟缓的重要因素,儿童视屏时间每增加1 h,其语言发育商平均下降1.626。结论 视屏时间是影响儿童语言发展的重要因素,建议家庭内限制每天儿童视屏的时间,并从家长自身做起,增加面对面的情感交流机会以促进儿童早期发育。
