Abstract

Overview

The study aimed to evaluate the impact of Wi-Fi, cordless, and mobile phone usage on childhood behavioral problems in a Japanese cohort.

Background

With the integration of technology into daily life, understanding its effects on children's health is crucial. The relationship between various communication devices and behavioral issues was examined in this research.

Methods

  • Subjects: 2,465 children aged 8-17 from the Hokkaido Study on Environment and Children's Health.
  • Duration: Data collected from Oct 2020-Jan 2021 with follow-ups Sep 2021-Mar 2022.
  • Assessment: Gathered data on residential Wi-Fi and device usage, analyzing behavior through the Strength and Difficulties Questionnaire.

Findings

  • Significant findings were not observed with Wi-Fi and short (<5 mins) mobile network calls.
  • Home cordless phone use and less frequent cordless calls were linked to behavioral improvements.
  • Conversely, longer (>40 mins/week) internet calls on mobile phones showed increased behavioral difficulties.

Conclusion

The study presents mixed results, suggesting minimal influential effects by RF-EMF from residential sources. Further in-depth studies are recommended to explore these associations comprehensively.
