Occupational exposure to extremely low-frequency magnetic fields and electrical shocks and acute myeloid leukemia in four Nordic countries

摘要: We studied the association between occupational exposure to extremely low-frequency magnetic fields (ELF-MF) and electrical shocks acute myeloid leukemia (AML) in Nordic Occupational Cancer cohort (NOCCA). included 5,409 adult AML cases diagnosed 1961 2005 Finland, Iceland, Norway, Sweden 27,045 controls matched by age, sex, country. Lifetime ELF-MF risk of were assigned jobs reported censuses using job-exposure matrices. estimated hazard ratios (HRs) 95 % confidence intervals (95 % CIs) conditional logistic regression adjusted for concurrent exposures relevant (e.g., benzene, ionizing radiation). conducted sensitivity analyses with different assumptions assess robustness our results. Approximately 40 % subjects ever occupationally exposed low levels 7 % high ELF-MF, whereas 18 % at 15 % shocks. did not observe an neither nor AML. The HR was 0.88 CI 0.77–1.01) 0.94 0.85–1.05) as compared those background-level exposure. Results remained materially unchanged assumptions. Our results do support or electric shock
