【 摘 要 】

Recent publicationsrenewed interest in assessing potential health risks for subjects living closeto transmission lines. This study aimed at evaluating the association of bothdistance of home address to the nearest overhead transmission line and of thecalculated magnetic fields from the power lines and mortality from leukemia,brain cancer, and amyotrophic lateral sclerosis. We carried out a death certificatebased case-control study accessing adult mortality in the Metropolitan Regionof São Paulo, in Brazil. Analysis included 1,857 cases of leukemia, 2,357of brain cancer, 367 of amyotrophic lateral sclerosis, and 4,706 as controls.An increased risk for mortality from leukemia among adults living at closerdistances to transmission lines compared to those living further then 400 mwas found. Risk was higher for subjects that lived within 50 m from power lines(OR=1.47; 95% CI=0.99-2.18). Similarly, a small increase in leukemia mortalitywas observed among adults living in houses with higher calculated magnetic fields(OR=1.61; 95% CI=0.91-2.86 for those exposed to magnetic fields >0.3 µT).No increase was seen for brain tumours or amyotrophic lateral sclerosis. Ourfindings are suggestive of a higher risk for leukemia among subjects livingcloser to transmission lines, and for those living at homes with higher calculatedmagnetic fields, although the risk was limited to lower voltage lines.
