BACKGROUND: Several studies have identified occupational exposure to extremely low-frequency electromagnetic fields (EMF) as a potential risk factor for @entity179 , but the evidence is contradictory and inconclusive. METHODS: We conducted a cohort study to explore these associations. We studied all economically active individuals in the Swedish 1980 census (4,812,646 subjects), and followed them for @entity179 mortality from 1981 through 1995. Information about occupation was available for 1970 and 1980. A job-exposure matrix based on magnetic field measurements was used to assess EMF exposure. RESULTS: An increased risk of @entity195 mortality was observed among @entity1 exposed both in 1970 and 1980 (relative risk = 2.3; 95% confidence interval = 1.6-3.3 for exposure >/=0.5 microT). The associations were most pronounced for early-onset @entity195 mortality or with follow-up limited to 10 years after the last known occupation. @entity746 was not associated with EMF exposure, but the risk estimate with "electrical and electronics work" was 1.4 (95% confidence interval = 1.1-1.9). CONCLUSIONS: Our study gives some support to the hypothesis that EMF exposure increases the risk of early-onset @entity195 , and suggests that magnetic field exposure may represent a late-acting influence in the disease process. @entity1457 is an unlikely explanation for the increased risk of @entity746 in "electrical and electronics work" in this study.
