【摘要】 目的：了解上海市徐汇区2～3岁幼儿屏幕暴露及屏幕内容特点，并分析其影响因素，为家庭幼儿屏幕管理提供科学依据。方法：2023年2—7月采用方便抽样法抽取徐汇区所辖全部13家社区儿童保健门诊的864名2～3岁幼儿，对其抚养人进行在线问卷调查，采用多因素logistic回归分析幼儿屏幕暴露时长及屏幕内容的影响因素。结果：864名2～3岁幼儿中，有屏幕暴露者137人，屏幕暴露发生率为15.9%。平均每日屏幕暴露时间为30 (20,60) min。2岁、3岁幼儿屏幕暴露发生率分别为12.9%(76/591)和22.3%(61/273)。多因素logistic回归分析结果显示，3岁（OR=1.627），父亲文化程度为大专及以下（OR=1.747），抚养人不陪伴幼儿使用电子产品（OR=2.137），抚养人偶尔监管（OR=1.622）、不监管幼儿使用电子产品（OR=9.007）是2～3岁幼儿屏幕暴露的独立危险因素（P<0.05）。屏幕内容方面，325人（37.6%）以教育类为主，539人（62.4%）以非教育类为主。父母看护（OR=1.908）、抚养人陪伴幼儿使用电子产品（OR=1.765）与幼儿观看教育类屏幕内容呈正相关（P<0.05），抚养人允许幼儿使用电子产品（OR=0.305）与幼儿观看教育类屏幕内容呈负相关（P<0.05）。结论：2～3岁幼儿屏幕暴露问题需引起重视，应加强宣教和亲子陪伴，科学规范幼儿的屏幕暴露行为。更多还原

【Abstract】 OBJECTIVETo investigate the characteristics of screen exposure and screen content of children aged 2～3 years in Xuhui District, and to analyze its determinants, in order to provide a scientific basis for the management of children’s screens at home. METHODS A total of 864 diaspora children aged 2～3 years in all 13 communities in Xuhui District of Shanghai were selected by convenient sampling method from February to July in 2023, and their caregivers were surveyed by online questionnaires, and the influencing factors of children’s screen exposure were analyzed by multivariate logistic regression. RESULTS Among 864 children aged 2～3 years, 137 had screen exposure, with a screen exposure incidence of 15.9%. The average daily screen time was 30(20,60) minutes. The incidence of screen exposure was 12.9%(76/591) and 22.3%(61/273) in the 2-year-old and 3-year-old groups.Logistic multifactorial regression analyses showed that the incidence of screen exposure in the 3-year-old group(OR=1.627), father’s education level was college or below(OR=1.747), children without being accompanied to use electronics(OR=2.137) and occasionally supervised(OR=1.622), not supervise children’s use of electronics(OR=9.007) were independent risk factors for screen exposure in children aged 2～3 years(P<0.05). In terms of screen content, 325(37.6%) were mainly educational and 539(62.4%) were non-educational. Multiple caregivers(OR=1.908) and unaccompanied use of electronic products(OR=1.765)were positively associated with children’s viewing of non-educational screen content(P<0.05). Caregiver disallowing children to use electronic products(OR=0.305) was negatively associated with early childhood viewing of non-educational screen content(P<0.05). CONCLUSION The problem of children’s screen exposure in children aged 2～3 years should be paid attention, strengthen education and parent-child accompaniment, and scientifically regulate children’s screen exposure behavior.更多还原
