ABSTRACT
AIMS:
To evaluate selected birth outcomes from a published Norwegian cohort study in a nested case-control design with improved exposure data.METHODS:
Two controls matched for sex, year of birth, and municipality were selected randomly for children with the following defects central nervous system (CNS) defects, cardiac defects, respiratory system defects, oesophageal defects, and clubfoot. The distances between maternal addresses, during pregnancy, and power lines were obtained from maps mainly of scale 15000. The magnetic fields in the residences were estimated based on distance, current, voltage, and configuration.RESULTS:
The highest increased risks were seen for hydrocephalus (OR 1.73, 95% CI 0.26 to 11.64) and for cardiac defects (OR 1.54, 95% CI 0.89 to 2.68).CONCLUSION:
This study does not support the hypothesis that residential exposure to electromagnetic fields from power lines causes any of the investigated outcomes.
