Abstract

Overview

This study investigates the connection between extremely low-frequency magnetic fields (ELF-MFs) and childhood leukemia, focusing on areas with significant children's ELF-MF exposure, such as Mexico City.

Objective

The main objective is to explore the association between ELF-MF exposure and the increase in risk for B-lineage acute lymphoblastic leukemia (B-ALL).

Methodology

  • A case-control study in Mexico City during 2010-2011.
  • Included were 290 new B-ALL patients and 407 controls under 16 years, matched by sex, age, and health institution.
  • Residential 24-hour ELF-MF measurements were acquired.

Findings

Exposure levels and associated risks are quantified, with increased odds ratios (aOR) seen with higher exposure levels:

  • Exposure ≥0.2 μT = aOR 1.26 (95% CI: 0.84-1.89)
  • Exposure ≥0.3 μT = aOR 1.53 (95% CI: 0.95-2.48)
  • Exposure ≥0.4 μT = aOR 1.87 (95% CI: 1.04-3.35)
  • Continuous exposure increment per 0.2 μT = aOR 1.06 (95% CI: 1.01-1.12)

Conclusion

There is a notable association between higher exposures to ELF-MFs and increased risk of B-ALL in children, underlining significant health implications in areas with elevated ELF-MF exposure.
