The study found an association between wiring configuration and childhood leukemia risk but no clear link with measured electric or magnetic fields.

Plain English Summary

Summary written for general audiences

Researchers conducted a case-control study of 232 cases and 232 controls aged birth to 10 years in Los Angeles County from 1980 to 1987. Magnetic field measurements were taken in the child's bedroom over 24 hours or longer for 164 cases and 144 controls, and spot measurements for 140 cases and 109 controls. No clear associations were seen between leukemia risk and measured magnetic or electric fields. An association was observed between the Denver Wertheimer-Leeper wiring configuration and childhood leukemia risk with an odds ratio of 2.15. Cases were more likely than controls to report use of several appliances that produce high electric and magnetic fields.

Why This Matters

The authors concluded that the results support an association between childhood leukemia risk and wiring configuration but not direct measurements of electric and magnetic fields. An erratum for the article was published in 1993.

Quick Questions About This Study

The researchers used a case-control study of children aged birth to 10 years in Los Angeles County.
Exposure was assessed by 24-hour bedroom magnetic field measurements, spot measurements of magnetic and electric fields, wiring configuration, and self-reported appliance use.
No clear associations between leukemia risk and measured magnetic or electric fields were seen.
An association was observed between the Denver Wertheimer-Leeper wiring configuration and childhood leukemia risk with an odds ratio of 2.15 (95% CI 1.08-4.28, p for trend = 0.008).
Cases were more likely than controls to report use of several appliances that produce high electric and magnetic fields.
