Objective To study the current status and influencing factors of screen time among preschool children in Shanghai,and to provide scientific reference for further formulating relevant intervention measures for preschool children.Methods The basic information and screen time of children were collected from questionnaires of parents of 931 preschool children aged 3-6 years in Shanghai by convenience sampling method from March 2018 to September 2019.The influencing factors for average daily screen time ≥1 h were analyzed using logistic regression analy-sis.Results The average daily screen time of 931 children was(1.74±0.65)h/d,and the average screen time was(1.56±0.59)h/d on weekdays and the average screen time was(2.20±0.81)h/d on weekends,thus the average screen time on weekdays was significantly shorter than on weekends(t=19.487,P＜0.001).Multivariate analysis showed that the frequency of watching TV during meals＞5 times/week(OR=1.669),the frequency of using elec-tronic products as a reward tool＞5 times/week(OR=1.631),the time of using electronic products more than 1 hour approved by parents(OR=1.687)and the mother's education level of university(OR=1.483)and Master de-gree or above(OR=1.624)were independent risk factors affecting the average daily screen time of preschool children(P＜0.05).Conclusion It is common that average daily screen time in Shanghai preschool children is longer than the recommended time(1 h/d).The frequency of watching TV during meals,frequency of using electronic products as a reward tool,time of using electronic products approved by parents and mother's education level are the indepen-dent risk factors affecting of average daily screen time of preschool children.Thus,it is necessary to pay attention to the above factors and take relevant intervention measures.
