Electronic screens have become an integral part of modern life, accompanied with growing concerns for children's neuropsychological development. This study aimed to evaluate the associations between measures of early life screen exposure and hyperactive behaviors among preschool children. The study also aimed to investigate their cumulative effects and the critical window for these associations. A cross-sectional survey was conducted among 52 625 mother-child dyads at preschools in LongHua District of Shenzhen, China. A self-administered structured questionnaire was used to assess socio-demographic characteristics, duration of children's electronic screen exposure in each of the first 3 years following birth and the presence of current hyperactive behaviors. A series of logistic regression models were used to examine the relationship between previous screen time and current hyperactive behaviors. A crossover analysis was used to explore the critical window for a significant relationship between screen time and hyperactive behaviors. We found that exposure to electronic screens in the first 3 years of life was associated with hyperactive behaviors in preschool children. A cumulative effect was shown in children with an average daily screen time less than 60 min, with adjusted ORs increasing from 1.262 to 1.989 as screen exposure years increased from 1 to 3 years. A critical window was identified in that children in the first 2 years after birth were vulnerable to electronic screen exposure. Exposure to televisions, mobile phones, and computers were all related to elevated risks for hyperactive behaviors. In conclusion, early screen exposure appears to increase the risk for hyperactive behaviors in preschool children with the presence of a cumulative effect, a critical window and different electronic screens having similar effects.
电子屏幕已成为现代生活中不可或缺的一部分，与此同时，人们对儿童神经心理发展的担忧也与日俱增。本研究旨在评估学前儿童早期生活中屏幕暴露量与多动行为之间的关联。该研究还旨在探究这些关联的累积效应以及关键窗口期。在中国深圳龙华区的幼儿园对52625对母子进行了一项横断面调查。采用自填式结构化问卷来评估社会人口学特征、儿童出生后头3年中每年的电子屏幕暴露时长以及当前是否存在多动行为。使用一系列逻辑回归模型来检验既往屏幕使用时间与当前多动行为之间的关系。采用交叉分析来探索屏幕使用时间与多动行为之间显著关联的关键窗口期。我们发现，生命头3年接触电子屏幕与学前儿童的多动行为有关。对于平均每日屏幕使用时间少于60分钟的儿童存在累积效应，随着屏幕暴露年限从1年增加到3年，调整后的比值比从1.262增加到1.989。确定了一个关键窗口期，即出生后头2年的儿童易受电子屏幕暴露的影响。接触电视、手机和电脑均与多动行为风险升高有关。总之，早期屏幕暴露似乎会增加学前儿童出现多动行为的风险，存在累积效应、关键窗口期，且不同电子屏幕有类似影响。
