Abstract

Since the first paper by Milham et al. suggested that occupational exposure to an electromagnetic field (EMF) could increase the risk of adult leukemia, many epidemiological studies on this problem have been published. In this report the method of meta-analysis was used to summarize the results from these papers quantitatively. The combined relative risk of all leukemia (RR=1.11), as well as acute lymphocytic leukemia (RR=1.38), acute myeloid leukemia (RR=1.07) and chronic lymphocytic leukemia (RR=1.14) increased but not significantly. So far, it is difficult to make a consistent conclusion about the relationship of the occupational exposure to EMF and adult leukemia. Further carefully designed case-control and cohort studies using the more valid means of exposure assessment are required.

Main findings

Meta-analysis of epidemiological studies found combined relative risks above 1.0 for all leukemia (RR=1.11) and for acute lymphocytic (RR=1.38), acute myeloid (RR=1.07), and chronic lymphocytic leukemia (RR=1.14), but these increases were not statistically significant. The authors state it is difficult to make a consistent conclusion and call for better-designed studies with more valid exposure assessment.
