Association between estimated whole-brain radiofrequency electromagnetic fields dose and cognitive function in preadolescents and adolescents.

摘要: Objective: To investigate the association between estimated whole-brain radiofrequency electromagnetic fields (RF-EMF) dose, using an improved integrated RF-EMF exposure model, and cognitive function in preadolescents adolescents. Methods: Cross-sectional analysis aged 9–11 years adolescents 17–18 from Dutch Amsterdam Born Children their Development Study (n = 1664 preadolescents) Spanish INfancia y Medio Ambiente Project 1288 n 261 adolescents), two population-based birth cohort studies. Overall doses (mJ/kg/day) were for several sources together including mobile Digital Enhanced Cordless Telecommunications phone calls (named calls), other uses than calling, tablet use, laptop use screen activities), far-field sources. We also these three groups separately (i.e. calls, activities, far-field) that lead to different patterns of exposure. assessed non-verbal intelligence preadolescents, information processing speed, attentional function, flexibility working memory semantic fluency validated neurocognitive tests. Results: Estimated overall dose was 90.1 mJ/kg/day (interquartile range (IQR) 42.7; 164.0) 105.1 (IQR 51.0; 295.7) Higher all associated with lower score (−0.10 points, 95% CI -0.19; −0.02 per 100 increase each exposure). However, none related any outcome or Conclusions: Our results suggest higher brain is but not outcomes. Given cross-sectional nature study, small effect sizes, unknown biological mechanisms, we cannot discard our resultsare due chance finding reverse causality. Longitudinal studies on are needed.
