  1. Fulltext. Power-frequency electric and magnetic fields and risk of childhood leukemia in Canada.

    Article - En anglais


    In a case-control study of childhood leukemia in relation to exposure to power-frequency electric and magnetic fields (EM F), 399 children resident in five Canadian provinces who were diagnosed at ages 0-14 years between 1990 and 1994 (June 1995 in British Columbia and Quebec) were enrolled, along with 399 controls.

    Exposure assessment included 48-hour personal EMF measurement, wire coding and magnetic field measurements for subjects'residences from conception to diagnosis/reference date, and a 24-hour magnetic field bedroom measurement.

    Personal magnetic fields were not related to risk of leukemia (adjusted odds ratio (OR)=0.95, p for trend=0.73) or acute lymphatic leukemia (OR=0.93, p for trend=0.64).

    There were no clear associations with predicted magnetic field exposure 2 years before the diagnosis/reference date or over the subject's lifetime or with personal electric field exposure.

    A statistically nonsignificant elevated risk of acute lymphatic leukemia was observed with very high wiring configurations among residences of subjects 2 years before the diagnosis/reference date (OR=1.72 compared with underground wiring, 95% confidence interval 0.54-5.45).

    These results provide little support for a relation between power-frequency EMF exposure and risk of childhood leukemia.
