Chicken or egg? Attribution hypothesis and nocebo hypothesis to explain somatization associated to perceived RF-EMF exposure

Abstract

Category: Epidemiology Tags: RF-EMF, somatization, attribution hypothesis, nocebo effect, health risk, policy, symptom reporting DOI: 10.3389/fpubh.2025.1561373 URL: frontiersin.org Overview The aim of this study is to understand the temporal relationship between somatization usually attributed to RF-EMFs (Radiofrequency Electromagnetic Fields) and to evaluate both the attribution hypothesis and the nocebo hypothesis in this context. Method This longitudinal study analyzed data from the Dutch Occupational and Environmental Health Cohort Study (AMIGO), which included: - A baseline questionnaire from 2011 with 14,829 participants - A follow-up questionnaire from 2015 with 7,904 participants Participants provided information on health status, perceived environmental exposures, and demographics. Two sets of multiple regression analyses were used to assess the attribution and nocebo hypotheses. Findings Results show that the attribution hypothesis more frequently explained symptom reporting associated with perceived RF-EMF base station exposure and perceived electricity exposure, compared to the nocebo hypothesis. Discussion This finding contrasts with much of the existing literature, which generally points to the nocebo effect as the primary explanation for somatization in response to RF-EMF exposure. While the presence of a nocebo effect is not entirely ruled out, especially over other timescales, this result carries significant implications for policymaking. Highlighting the attribution hypothesis underscores the discomfort experienced by individuals with unexplained symptoms and their search for plausible explanations related to RF-EMF exposure. ⚠️ This study supports a connection between perceived electromagnetic fields and reported health risks, necessitating ongoing attention for EMF safety and public health guidance.

Main findings

In longitudinal analyses (2011 baseline; 2015 follow-up), the attribution hypothesis more frequently explained symptom reporting associated with perceived RF-EMF base station exposure and perceived electricity exposure than the nocebo hypothesis. The authors note this contrasts with much existing literature emphasizing nocebo explanations, while not fully ruling out nocebo effects on other timescales.

Outcomes measured

• Somatization
• Symptom reporting
• Perceived health risk/health status

Limitations

• Exposure was perceived (self-reported) rather than objectively measured
• Follow-up sample was smaller than baseline (2015: 7,904 vs 2011: 14,829)
• Specific RF-EMF exposure metrics (e.g., frequency, intensity) not reported in the abstract

Suggested hubs
