Abstract

OBJECTIVE: The aim of the cross-sectional study was to test the hypothesis that exposure to continuous low-level radio frequency electromagnetic fields (RF-EMFs) emitted from mobile phone base stations was related to various health disturbances. METHODS: For the investigation people living mainly in urban regions were selected from a nationwide study in 2006. In total, 3526 persons responded to a questionnaire (response rate 85%). For the exposure assessment a dosimeter measuring different RF-EMF frequencies was used. Participants answered a postal questionnaire on how mobile phone base stations affected their health and they gave information on sleep disturbances, headaches, health complaints and mental and physical health using standardised health questionnaires. Information on stress was also collected. Multiple linear regression models were used with health outcomes as dependent variables (n = 1326). RESULTS: For the five health scores used, no differences in their medians were observed for exposed versus non-exposed participants. People who attributed adverse health effects to mobile phone base stations reported significantly more sleep disturbances and health complaints, but they did not report more headaches or less mental and physical health. Individuals concerned about mobile phone base stations did not have different well-being scores compared with those who were not concerned. CONCLUSIONS: In this large population-based study, measured RF-EMFs emitted from mobile phone base stations were not associated with adverse health effects.

Main findings

Across five health scores, no differences in medians were observed for exposed versus non-exposed participants based on measured RF-EMF from mobile phone base stations. Participants who attributed adverse health effects to base stations reported more sleep disturbances and health complaints, but not more headaches or worse mental/physical health; concern about base stations was not associated with different well-being scores.

Outcomes measured

  • Sleep disturbances
  • Headaches
  • Health complaints
  • Mental health
  • Physical health
  • Stress
  • Self-attributed adverse health effects from base stations
  • Concern about base stations / well-being scores

Limitations

  • Cross-sectional design (exposure and outcomes assessed at the same time)
  • Only a subset was included in regression models (n = 1326)
  • Health outcomes were self-reported via postal questionnaire
