The effect of ELF-MF on human health is still controversial, particularly as regards long-term health effects like cancer. The literature does suggest, however, that they could be involved in the occurrence of brain tumors, although results concerning residential exposure are scarce. Our objective was to investigate the association between residential proximity to power lines and brain tumors among adults in France by using a geographical information system.CERENAT is a population-based case-control study carried out in France in 2004-2006. We used geographical data sources on power line location to create exposure scores based on distance between residence and power lines, and on the number of lines near residences. Conditional logistic regression for matched sets was used to estimate Odds Ratios (ORs) and 95% confidence intervals (95%CI).We found significant associations between cumulated duration living at <50 m to high voltage lines and: i) all brain tumors (OR 2.94; 95%CI 1.28-6.75); ii) glioma (OR 4.96; 95%CI 1.56-15.77). Further investigations are needed, particularly to improve the quality and availability of geographical and technical data on power lines.

普通人群居住在靠近电力线的地方，容易患脑瘤。

ELF-MF对人类健康的影响仍然存在争议，特别是在长期健康影响方面，例如癌症。文献确实表明，尽管有关住宅暴露的结果很少，但它们可能与脑肿瘤的发生有关。我们的目标是使用地理信息系统调查法国成年人中住宅附近的电力线与脑肿瘤之间的关系。CERENAT是一项基于人群的病例对照研究，于2004年至2006年在法国进行。我们使用了有关电力线位置的地理数据源，以根据住宅与电力线之间的距离以及住宅附近的线数来创建暴露分数。使用匹配集的条件逻辑回归来估计赔率（OR）和95％置信区间（95％CI）。我们发现在<50 m到高压线路的累积持续时间与以下各项之间存在显着关联：i）所有脑瘤（OR 2.94； 95％CI 1.28-6.75）；ii）神经胶质瘤（OR 4.96； 95％CI 1.56-15.77）。需要进行进一步的调查，尤其是要提高电力线上的地理和技术数据的质量和可用性。
