The role of occupational exposure to heat and electromagnetic fields was investigated in a case-control study of male breast cancer. Seventy-one cases reported to the New York State Tumor Registry between 1979 and 1988 were compared with 256 healthy male controls. Controls were frequency matched to cases by race, year of diagnosis, and age in 5-year intervals. Unconditional logistic regression modeling indicated that males with occupations that involved heat exposure had an elevated risk for the disease. The age- and county-adjusted odds ratio was 2.3 (95% confidence interval (CI) 0.95-5.3). Exposure to heat on the job could influence testicular function. No increase in disease risk was observed for males believed to have occupational exposure to electromagnetic fields (odds ratio = 0.7, 95% CI 0.3-1.9).
在一项男性乳腺癌病例对照研究中，对职业性热暴露和电磁场暴露的作用进行了调查。将1979年至1988年期间向纽约州肿瘤登记处报告的71例病例与256名健康男性对照进行了比较。对照按种族、诊断年份和年龄每5年间隔与病例进行频率匹配。无条件逻辑回归模型表明，从事热暴露职业的男性患该病的风险升高。年龄和县域调整后的优势比为2.3（95%置信区间（CI）0.95 - 5.3）。工作时的热暴露可能会影响睾丸功能。对于被认为有职业性电磁场暴露的男性，未观察到疾病风险增加（优势比 = 0.7，95% CI 0.3 - 1.9）。
