Case‐control study on occupational exposure to extremely low‐frequency electromagnetic fields and glioma risk

Background Exposure to extremely low‐frequency electromagnetic fields (ELF‐EMF) was in 2002 classified as a possible human carcinogen, Group 2B, by the International Agency for Research on Cancer at WHO. Methods Life time occupations were assessed in case‐control studies during 1997‐2003 and 2007‐20...

Description
Summary:Background Exposure to extremely low‐frequency electromagnetic fields (ELF‐EMF) was in 2002 classified as a possible human carcinogen, Group 2B, by the International Agency for Research on Cancer at WHO. Methods Life time occupations were assessed in case‐control studies during 1997‐2003 and 2007‐2009. An ELF‐EMF Job‐Exposure Matrix was used for associating occupations with ELF exposure (μT). Cumulative exposure (μT‐years), average exposure (μT), and maximum exposed job (μT) were calculated. Results Cumulative exposure gave for astrocytoma grade IV (glioblastoma multiforme) in the time window 1‐14 years odds ratio (OR) = 1.9, 95% confidence interval (CI) = 1.4‐2.6, p linear trend
