240例幼儿视屏时间与家庭视屏环境的相关性研究

Study on the correlation between screen time and home video environment in 240 infants

目的 探索儿童视屏时间与家庭视屏环境的关系。方法 采用随机抽样选取2018年3-8月于上海市儿童医院儿童保健科体检的240例正常儿童为研究对象,利用自行设计的幼儿视屏时间流行病学调查问卷、家庭养育环境问卷对研究对象进行横断面调查。结果 本研究共纳入研究对象240例,70%的儿童年龄为12~36月龄。以儿童平均每天视屏时间是否超过1 h将研究对象分为<1 h/d和≥1 h/d两组,结果显示父母亲文化程度越高儿童视屏时间<1 h/d的比例越高,家庭养育环境越好儿童视屏时间<1 h/d的比例越高。与视屏≥1 h/d组相比,在<1 h/d组儿童的母亲在上述3方面的平均视屏时间较短,差异有统计学意义(P<0. 05)。但父母亲工作日、周末与孩子接触时间,父亲视屏时间在两组的差异无统计学意义(P>0. 05)。多因素回归分析结果显示,在调整了父亲文化程度、母亲文化程度、家庭养育环境等因素后,母亲视屏用于工作时间、母亲视屏用于闲暇时间是影响儿童视屏的危险因素,OR值分别为1. 244、1. 383。结论 幼儿视屏时间受家庭视屏环境特别是母亲视屏时间影响,建议家庭增加高质量亲子活动数量,对儿童及家长的视屏行为予以约束。

Objective To explore the correlation between screen time and home video environment in infants.Methods A random sampling method was used to select 240 normal children from Department of Child Healthcare,Shanghai Children's Hospital from March to August in 2018.A self-designed children screen time epidemiological questionnaire and parenting environment questionnaire were used for cross-sectional study.Results A total of 240 children were included in the study,seventy percent of the children were aged 12-36 months.The children were divided into<1 hour per day group and≥1 hour per day group according to daily screen time,the higher the parental educational levels were,the higher the proportion of children with screen time<1 hour per day was,the better the family paren-ting environment was,the higher the proportion of children with screen time<1 hour per day was.Compared with≥1 hour per day group,the mean maternal screen time of the above-mentioned three aspacts in<1 hour per day group was shorter,there was statistically significant difference(P<0.05).There was no statistically significant difference in parental contact time with children on weekday and weekend,paternal screen time between the two groups(P>0.05).Multivariate regression analysis showed that maternal working screen time and leisure screen time were risk factors of screen time in children after adjusting paternal educational level,maternal educational level,and family par-enting environment,OR values were 1.244 and 1.383,respectively.Conclusion Children's screen time is affected by family screen envi-ronment,especially maternal screen time.It is suggested that the families should increase the quantity of high-quality parent-child activities and restrict children and parental screen behavior.
