Abstract

Objective: Epidemiologic evidence for the association between electromagnetic fields and amyotrophic lateral sclerosis, the most common form of motor neuron disease (MND), has been inconclusive. We evaluated the association between electromagnetic fields and MND among workers in occupations potentially exposed to magnetic fields

Methods: MND mortality (ICD-9 335.2) was examined in the National Longitudinal Mortality Study using multivariable proportional hazards models. Occupational exposure to magnetic fields was determined on the basis of a population-based job-exposure matrix. Age at entry, education, race, sex, and income were considered for inclusion as covariates

Results: After adjusting for age, sex, and education, there were no increased risks of MND mortality in relation to potential magnetic field exposure, with hazard ratios around the null in all magnetic field exposure quartiles

Conclusions: Our study does not provide evidence for an association between magnetic field exposure and MND mortality.

Author Commentary

This was my very first published manuscript! I was a graduate student at the University of Rochester and my advisor, Edwin, urged me to work on an analysis that could be published. My time at Xerox increased my interest in occupational exposures and their effect on health. So, with that interest and the support of my advisor, I did this analysis.
