Abstract

Critical window for the association between early electronic screen exposure and hyperactive behaviors in preschool children Cai JY, Strodl E, Yang WK, Yin XN, Wen GM, Sun DL, Xian DX, Zhao YF, Chen WQ. Critical window for the association between early electronic screen exposure and hyperactive behaviors in preschool children. Psychol Health Med. 2023 Mar 16:1-13. doi: 10.1080/13548506.2023.2192039. Abstract 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. pubmed.ncbi.nlm.nih.gov

Main findings

In a cross-sectional survey of 52,625 mother-child dyads, electronic screen exposure in the first 3 years of life was associated with elevated odds of hyperactive behaviors in preschool children. Among children with average daily screen time <60 minutes, adjusted ORs increased from 1.262 to 1.989 as screen exposure years increased from 1 to 3 years. A critical window was identified in the first 2 years after birth, and exposure to televisions, mobile phones, and computers were each related to elevated risks.

Outcomes measured

  • Hyperactive behaviors (current)

Limitations

  • Cross-sectional design (temporal direction/causality not established)
  • Screen exposure and hyperactive behaviors assessed by self-administered questionnaire (potential reporting/recall bias)
  • Exposure characterized as screen time rather than EMF-specific metrics (no frequency/SAR reported)
