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 1:5000. 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.
目的
在一项巢式病例对照研究中，利用改进的暴露数据评估已发表的挪威队列研究中的特定出生结局。
方法
针对患有以下缺陷的儿童，随机选择两名按性别、出生年份和市政当局匹配的对照：中枢神经系统（CNS）缺陷、心脏缺陷、呼吸系统缺陷、食管缺陷和马蹄内翻足。孕期母亲住址与输电线之间的距离主要从比例为1:5000的地图上获取。根据距离、电流、电压和配置估算住宅中的磁场。
结果
脑积水（比值比1.73，95%可信区间0.26至11.64）和心脏缺陷（比值比1.54，95%可信区间0.89至2.68）的风险增加最高。
结论
本研究不支持以下假设：住宅暴露于输电线产生的电磁场会导致任何所研究的结局。
