Exposure to extremely low-frequency electromagnetic fields (ELF-EMF) was in 2002 classified as a possible human carcinogen, Group 2B, by the International Agency for Research on Cancer at WHO based on an increased risk for childhood leukemia. In case-control studies on brain tumors during 1997-2003 and 2007-2009 we assessed lifetime occupations in addition to exposure to different agents. The INTEROCC ELF-EMF Job-Exposure Matrix was used for associating occupations with ELF-EMF exposure (T) with meningioma. Cumulative exposure (T-years), average exposure (T), and maximum exposed job (T) were calculated.
No increased risk for meningioma was found in any category. For cumulative exposure in the highest exposure category 8.52+ T years odds ratio (OR) = 0.9, 95% confidence interval (CI) = 0.7-1.2, and linear trend = 0.45 were calculated. No statistically significant risks were found in different time windows.
In conclusion occupational ELF-EMF was not associated with an increased risk for meningioma.
基于接触极低频电磁场（ELF-EMF）会增加儿童白血病的风险，世界卫生组织下属的国际癌症研究机构于 2002 年将其归为 2B 类人类可能致癌物。在 1997-2003 年和 2007-2009 年期间进行的脑肿瘤病例对照研究中，我们评估了一生中的职业，以及接触不同物质的情况。我们使用 INTEROCC ELF-EMF 职业暴露矩阵将职业与 ELF-EMF 暴露（T）与脑膜瘤联系起来。计算了累积暴露（T 年）、平均暴露（T）和最大暴露职业（T）。
在任何类别中，均未发现脑膜瘤风险增加。在最高暴露类别中，累积暴露 8.52+T 年的比值比（OR）为 0.9，95%置信区间（CI）为 0.7-1.2，线性趋势为 0.45。在不同的时间窗口中未发现具有统计学意义的风险。
总之，职业性 ELF-EMF 与脑膜瘤风险增加无关。
