Abstract: Objective To investigate the electronic screen exposure of preschool children in Longhua District of Shenzhen, and to analyze the influencing factors. Methods A total of 25 266 children in kindergarten in Longhua District of Shenzhen were selected as study subjects. A self-designed questionnaire (completed by their guardians) was used to investigate the use of electronic products in the families of preschoolers in April 2019. Results A total of 23 407 valid questionnaires were collected in this survey, of which 12 593 (53.80%) were boys and 10 814 (46.20%) were girls; and 17 188(73.43%) children were 5 years old. Among the surveyed children, the rate of excessive exposure to electronic screens (>1h/d) was 37.72%, and 6.40% of preschool children used electronic products for more than 2 hours per day. There were statistically significant differences between the excessive exposure group and the non-excessive exposure group in gender, household registration, parents' educational level, average monthly household income,whether exclusive electronic products,whether restriction of children's use of electronic products, whether living with elders, only children or not, and the type of main caregiver (P<0.05).Multivariate binary Logistic regression analysis showed that girls,mothers with college education or above,not living with elders,primary caregivers being parents or nannies/others,and no exclusive electronic products were protective factors for children's excessive exposure to electronic products(P<0.05).Non-household resident population,not-only child,and non-restriction of children's use of electronic products were risk factors for children's excessive exposure to electronic products(P<0.05). Conclusions The excessive use of electronic products in preschoolers is a common phenomenon in Longhua district, Shenzhen. Therefore, it is necessary to strengthen the intervention on the use time of electronic products in preschoolers, and pay more attention to the influence of family environmental factors.

摘要: 目的 了解深圳市龙华区学龄前儿童电子屏幕暴露情况,分析其影响因素。方法 以深圳市龙华区所有在园中班儿童25 266人作为研究对象,采用自编问卷(监护人填写)于2019年4月对龙华区学龄前儿童电子屏幕暴露情况进行调查。结果 本次调查共回收有效问卷23 407份,其中男童12 593人(53.80%),女童10 814人(46.20%);年龄分布以5岁儿童居多,共17 188人(73.43%);参与调查儿童中,电子屏幕过度暴露(每天使用电子产品含看电视累计超1h)率为37.72%,6.40%的学龄前儿童每天累计电子产品暴露超2h。过度暴露组与非过度暴露组儿童在性别、户籍、父母亲文化程度、家庭月均总收入、是否有专属电子产品、看护人是否限制使用电子产品、、是否与长辈同住、是否为独生子女、主要看护人类型比较差异均有统计学意义(P<0.05)。多因素Logistic回归分析显示,女童、母亲大专及以上文化程度、未与长辈同住、主要看护人是父母或保姆/其他、无专属的电子产品是儿童电子产品过度暴露的保护因素(P<0.05);常住人口(非户籍)、非独生子女、主要看护人不限制儿童使用电子产品是儿童电子产品过度暴露的危险因素(P<0.05)。结论 深圳市龙华区学龄前儿童电子相关产品过度暴露情况较为普遍,应加强对学龄前儿童电子产品使用时间的干预,需要特别关注家庭环境因素的影响。
