Abstract

RF EMR and Memory Performance: Sources of Uncertainty in Epidemiological Cohort Studies Brzozek C, Benke KK, Zeleke BM, Abramson MJ, Benke G.Radiofrequency Electromagnetic Radiation and Memory Performance: Sources of Uncertainty in Epidemiological Cohort Studies. Int J Environ Res Public Health. 2018 Mar 26;15(4). pii: E592. doi: 10.3390/ijerph15040592. Abstract Uncertainty in experimental studies of exposure to radiation from mobile phones has in the past only been framed within the context of statistical variability. It is now becoming more apparent to researchers that epistemic or reducible uncertainties can also affect the total error in results. These uncertainties are derived from a wide range of sources including human error, such as data transcription, model structure, measurement and linguistic errors in communication. The issue of epistemic uncertainty is reviewed and interpreted in the context of the MoRPhEUS, ExPOSURE and HERMES cohort studies which investigate the effect of radiofrequency electromagnetic radiation from mobile phones on memory performance. Research into this field has found inconsistent results due to limitations from a range of epistemic sources. Potential analytic approaches are suggested based on quantification of epistemic error using Monte Carlo simulation. It is recommended that future studies investigating the relationship between radiofrequency electromagnetic radiation and memory performance pay more attention to treatment of epistemic uncertainties as well as further research into improving exposure assessment. Use of directed acyclic graphs is also encouraged to display the assumed covariate relationship. Open access paper: mdpi.com

Main findings

This paper reviews and interprets sources of epistemic (reducible) uncertainty affecting epidemiological cohort studies (MoRPhEUS, ExPOSURE, HERMES) on mobile-phone RF-EMR exposure and memory performance. It notes that findings in this field have been inconsistent and attributes limitations to multiple epistemic sources (e.g., human error, model structure, measurement and communication errors), recommending improved exposure assessment and analytic approaches such as Monte Carlo simulation and use of directed acyclic graphs.

Outcomes measured

memory performance

Limitations

Review focused on uncertainty sources rather than providing new primary effect estimates
Inconsistent findings in the underlying cohort literature are noted, with limitations attributed to epistemic uncertainty sources
Exposure assessment improvement is highlighted as a need (implying current exposure assessment limitations)
