Abstract

Overview

The study focused on the impact of radiofrequency electromagnetic fields (RF-EMF) on cognitive functions in preadolescents and adolescents, providing insights into the effects of cumulative exposure from various sources, including mobile use and other screen-related activities.

Methods

  • Population: 1664 Dutch and 1549 Spanish youths
  • Exposure assessment: Whole-brain RF-EMF doses integrating various sources
  • Neurocognitive effects measured: non-verbal intelligence, information processing, attention, cognitive flexibility, working memory, and semantic fluency

Findings

Significant associations were found between higher RF-EMF exposure and lower non-verbal intelligence scores, specifically:

  • Estimated Exposure: Dutch and Spanish preadolescents - 90.1 mJ/kg/day; Spanish adolescents - 105.1 mJ/kg/day
  • Impact: Decrease of -0.10 points in non-verbal intelligence per 100 mJ/kg/day increase in exposure

Conclusion

This research suggests a potential negative impact of RF-EMF on cognitive functions, particularly non-verbal intelligence. It underscores the need for longitudinal studies to further explore these findings and investigate the underlying biological mechanisms.
