To explore the association between occupation and the occurrence of brain tumor, an epidemiologic study was conducted using data from the death certificates of 951 adult white male Maryland residents who died of brain tumor during the period 1969 through 1982. Compared with the controls, men employed in electricity-related occupations, such as electrician, electric or electronic engineer, and utility company serviceman, were found to experience a significantly higher proportion of primary brain tumors. An increase in the odds ratio for brain tumor was found to be positively related to electromagnetic (EM) field exposure levels. Furthermore, the mean age at death was found to be significantly younger among cases in the presumed high EM-exposure group. These findings suggest that EM exposure may be associated with the pathogenesis of brain tumors, particularly in the promoting stage.
为了探究职业与脑肿瘤发生之间的关联，利用1969年至1982年期间马里兰州951名死于脑肿瘤的成年白人男性居民的死亡证明数据进行了一项流行病学研究。与对照组相比，从事与电相关职业的男性，如电工、电气或电子工程师以及公用事业公司服务人员，被发现患原发性脑肿瘤的比例显著更高。发现脑肿瘤的优势比增加与电磁场（EM）暴露水平呈正相关。此外，在假定的高EM暴露组中，病例的平均死亡年龄明显更年轻。这些发现表明，EM暴露可能与脑肿瘤的发病机制有关，尤其是在促进阶段。
