Abstract

Overview

Investigation into the risks of childhood leukemia related to residential exposure to magnetic fields from transformer stations.

Background

  • Previous research indicates an elevated leukemia risk among children exposed to magnetic fields.
  • Consistency and data pertaining to exposure from different sources remain unclear.

Methods

Population-based case-control assessment involving 182 leukemia cases and 726 controls in Modena and Reggio Emilia, Northern Italy, adjusting for relevant confounders and assessing proximity using spatial buffers.

Findings

  • No significant association found between proximity to transformer stations and leukemia risk for most children.
  • Suggestive evidence of increased leukemia risk in children aged ≥5 years near transformer stations.

Conclusions

While the study found no general increased risk between residential proximity to transformer stations and childhood leukemia, there is some indication of increased risk for children aged ≥5 years, although with limited precision due to the small number of exposed children.
