Comments regarding: "Occupational exposure to high-frequency EMF & brain tumor risk in INTEROCC study: An individualized assessment approach" Mortazavi SMJ. Comments regarding: "Occupational exposure to high-frequency electromagnetic fields and brain tumor risk in the INTEROCC study: An individualized assessment approach". Environ Int. 2018 Aug 24. pii: S0160-4120(18)31561-7. doi: 10.1016/j.envint.2018.08.008. Abstract This commentary addresses the paper by Vila et al. entitled "Occupational exposure to high-frequency electromagnetic fields and brain tumor risk in the INTEROCC study: An individualized assessment approach" that is published in Environment International. The authors have examined the link between occupational exposures to radiofrequency (RF) and intermediate frequency (IF) electromagnetic fields (EMF) and glioma and meningioma brain tumor risk in the INTEROCC multinational population-based case-control study. This study showed no clear association with exposure to RF or IF EMFs and the risk of glioma or meningioma brain tumors. Recent studies show that in many cases there are large errors and/or major shortcomings in the studies claiming no link between mobile phone and brain cancer. Although the paper by Vila et al. is well-structured and can be considered as a significant contribution to this field, there are several items that merit further attention and are not fully addressed. These include the selection bias, confounding factors other than age, sex, region and country, and criteria used in this study for considering exposures as occupational. ncbi.nlm.nih.gov

Main findings

This is a commentary on the INTEROCC population-based case-control study assessing occupational exposure to radiofrequency (RF) and intermediate frequency (IF) EMF and risk of glioma and meningioma. The commentary reports that the INTEROCC study showed no clear association between RF/IF EMF exposure and glioma or meningioma risk, and raises concerns about potential selection bias, confounding, and criteria for defining occupational exposures.

Outcomes measured

• glioma
• meningioma
• brain tumor risk

Limitations

• Commentary; does not present new primary data
• Critiques potential selection bias in the underlying INTEROCC study
• Notes possible unaddressed confounding factors beyond age, sex, region, and country
• Questions criteria used for classifying exposures as occupational

Suggested hubs

• occupational-exposure (0.9)
  Focuses on occupational exposure to RF/IF EMF and brain tumor risk in the INTEROCC study.
