The relationship between various occupational exposures and brain cancer was investigated in a case-control study using mortality data from 202 males who died in East Texas from gliomas in 1969-1978 and 238 male controls randomly selected from all deaths in East Texas in 1969-1978. Using the occupational classification scheme of the U.S. Bureau of the Census, the risk for brain cancer was significantly increased for male workers employed in the transportation, communication, and utilities industries [odds ratio (OR) = 2.26, confidence intervals (CI) = 1.18-4.32]. Further examination of this finding showed that male workers employed in occupations associated with electricity or electromagnetic (EM) fields had an elevated risk for brain cancer (OR = 3.94, CI = 1.52-10.20). In addition, there was a linear relationship between the probability of exposure to EM fields and brain cancer. Significantly elevated risk for brain cancer was also found among male workers in the trucking industry.
在一项病例对照研究中，利用1969年至1978年在东得克萨斯死于神经胶质瘤的202名男性的死亡率数据以及从1969年至1978年东得克萨斯所有死亡人员中随机选取的238名男性对照，研究了各种职业暴露与脑癌之间的关系。根据美国人口普查局的职业分类方案，从事运输、通信和公用事业行业的男性工人患脑癌的风险显著增加[比值比（OR）=2.26，置信区间（CI）=1.18 - 4.32]。对这一发现的进一步研究表明，从事与电或电磁场（EM）相关职业的男性工人患脑癌的风险升高（OR = 3.94，CI = 1.52 - 10.20）。此外，接触电磁场的概率与脑癌之间存在线性关系。在运输行业的男性工人中也发现患脑癌风险显著升高。
