XXXX in welders and other workers exposed to high levels of magnetic fields.

BACKGROUND: Previous work has suggested an increase in risk of @entity746 ( @entity746 ) and @entity195 among workers exposed to extremely low-frequency magnetic fields (ELF-MF). We evaluated the relation between ELF-MF from occupational exposures and mortality from @entity179 . METHODS: The study was based on a cohort of Swedish engineering industry workers, comprising 537,692 @entity1 and 180,529 @entity1 . The cohort was matched against the 3 most recent censuses and The Causes of Death Registry. Levels of ELF-MF exposure were obtained by linking occupation according to the censuses to a job exposure matrix. We used 4 levels of exposure and considered both the primary and contributing causes of @entity204 , 1985-96. RESULTS: The risk of @entity195 as primary or contributing cause of @entity204 increased with increasing exposure to ELF-MF among both @entity1 and @entity1 , with a relative risk (RR) of 4.0 and a 95% confidence interval (95% CI) of 1.4-11.7 in the highest exposure group for both sexes combined. There was a RR of 2.2 (95% CI: 1.0-4.7) for @entity746 in the highest exposure group with the suggestion of an exposure-response relationship. No evidence of increased risk was seen for @entity191 or @entity15 . CONCLUSIONS: The findings support previous observations of an increased risk of @entity195 and @entity746 among employees occupationally exposed to ELF-MF. Further studies based on morbidity data are warranted.
