Abstract

Category: Epidemiology Tags: RF-EMF, neurodevelopment, infants, cohort study, EMF exposure, health risk, cognitive development DOI: 10.7759/cureus.87671 URL: cureus.com Overview Children are considered particularly susceptible to the health effects of radiofrequency electromagnetic fields (RF-EMF). This prospective cohort study was designed to investigate the association between RF-EMF exposure and neurodevelopmental changes in neonates and infants. The study followed 105 neonates born to enrolled pregnant women, tracking the cohort for one year. RF-EMF exposure was measured using a Selective Radiation Meter, while neurodevelopment was assessed via the Ages and Stages Questionnaire (ASQ-3). Household radiation exposure was categorized into tertiles (low, medium, high) for analysis. Findings - Median household radiation was measured at 8.66 (IQR: 1.58, 23.11) mW/m2, with the highest tertile having a median of 32.36 (IQR: 23.11, 45.60) mW/m2 (p=0.0001). - Significantly lower mean scores were observed in the middle and high radiation groups across gross motor, fine motor, and problem-solving domains. - Children in the 'high radiation' group had higher odds of being classified as 'monitor/refer' for fine motor (aOR: 2.74) and problem-solving (aOR: 3.67) domains. - Low birth weight was also a significant risk factor for adverse fine motor and problem-solving outcomes (aOR: 4.19 and 2.57, respectively). Conclusion After adjusting for low birth weight, higher household RF-EMF exposure was still strongly associated with poorer neurodevelopmental outcomes in domains such as problem-solving and personal-social skills. Low birth weight also contributed to poorer motor outcomes. Monitoring of neurodevelopment is recommended for children exposed to higher levels of RF-EMF—such as those living near cell phone towers or in homes with many gadgets. These findings add to the growing evidence that EMF exposure poses a health risk, particularly to the developing brain and cognitive abilities in infants. Additional Notes - Limitations include lack of prenatal cell phone use data, absence of parental interaction assessment, and single-point radiation measurement. - Further results from this cohort are anticipated, including additional developmental assessments with other validated tools.

Main findings

In 261 observations from 105 neonates followed for one year, higher household RF-EMF radiation levels were associated with lower mean scores in gross motor, fine motor, and problem-solving domains. Children in the high radiation group had higher adjusted odds of being classified as monitor/refer for fine motor (aOR 2.74, 95% CI 1.10-6.78) and problem-solving (aOR 3.67, 95% CI 1.41-9.55) compared with the low radiation group.
