Ecological momentary assessment study of exposure to RF EMF and non-specific physical symptoms with self-declared electrosensitives
Abstract
Overview
The main objective of this longitudinal study was to investigate the relationship between exposure to radiofrequency electromagnetic fields (RF EMF) and non-specific physical symptoms (NSPS) in individuals self-declaring as sensitive to RF EMF. It aims to distinguish findings between group-level and individual-level analyses.
Methodology
A total of 57 participants were equipped with a body worn exposimeter, a GPS logger, and an electronic diary that prompted them to fill out a health questionnaire at random intervals for five consecutive days.
Findings
- At the group level, no correlation was found between RF EMF exposure and NSPS.
- Significant within-person correlations were observed between exposure metrics and the severity of the most important health complaint and total NSPS in one participant.
- The study highlights the importance of analyzing data at the individual level, which might reveal different findings compared to group-level analysis.
Conclusion
This study concludes that individual data analysis might suggest potential health risks associated with RF EMF exposure, though these results require cautious interpretation due to possible confounding factors. It underscores the importance of precise control for various conditions, including location and activities during EMF exposure.
