Magnetic fields and cancer in children residing near Swedish high-voltage power lines
Authors not listed · 1993
Children living near high-voltage power lines with calculated magnetic fields of 0.2 microtesla or more had a relative risk of leukemia of 2.7.
Plain English Summary
A case-control study examined cancer incidence in children who lived within 300 meters of 220 and 400 kV power lines in Sweden from 1960 to 1985. Researchers identified 142 cancer cases, including 39 leukemia and 33 central nervous system tumor cases, and selected 558 controls from the study base. For childhood leukemia, the relative risk was 2.7 (95% CI 1.0-6.3) at 0.2 microtesla and 3.8 (95% CI 1.4-9.3) at 0.3 microtesla, with significant trends. No association was found for central nervous system tumors, lymphoma, or all childhood cancers combined.
Why This Matters
Exposure was assessed using both spot measurements and calculated magnetic fields that accounted for distance, line configuration, and historical load on the power lines. The leukemia risk estimates remained after adjustment for potential confounding factors.
