Residential exposure to magnetic fields from high-voltage power lines and risk of childhood leukemia
Abstract
Overview
Residential proximity to high-voltage power lines and its association with the risk of childhood leukemia is assessed in this Italian population-based case-control study.
Background
- Previous studies have shown inconsistencies regarding the risk of leukemia among children living close to power lines.
- The current study leverages more rigorous exposure assessments to clarify this potential association.
Methods
This analysis included a total of 182 childhood leukemia cases and 726 matched controls, accounting for various confounders such as proximity to petrol stations and traffic-related pollutants.
Findings
- Children living within 100 meters of high-voltage power lines had approximately twice the risk of childhood leukemia compared to those living 400 meters away or more.
- The risk association showed a non-linear pattern, increasingly significant at lesser distances.
Conclusion
The findings indicate a clear, albeit imprecise, increase in childhood leukemia risk in closer proximity to power lines, detailed by a dose-response relationship. This supports hypothesized risks associated with exposure to magnetic fields near residential areas.
