The mortality experience of a cohort of approximately 9,000 traced men employed at a Tennessee chemical plant was examined between 1972 and 1982. Statistically significant total mortality deficits of 41% to 46% and 14%, respectively, were observed compared with general population and occupational controls. Cancer deaths were 22% (significant) below expectation based on state and national vital statistics, whereas comparison with an employed group showed no difference. Significantly low mortality differentials were also reported for other major causes, including diseases of the circulatory, respiratory, and digestive systems. Analysis of the data by length of employment, payroll status, and chemical production division demonstrated no unusual patterns. The cohort's favorable mortality experience may be attributed to such factors as employee selectivity, health maintenance, accessibility to medical care, and less cigarette smoking.
1972年至1982年间，对田纳西州一家化工厂约9000名有记录的在职男性队列的死亡情况进行了调查。与一般人群和职业对照相比，分别观察到总死亡率显著下降41%至46%和14%。根据州和国家生命统计数据，癌症死亡人数比预期低22%（具有显著性），而与在职人群相比则无差异。其他主要死因的死亡率差异也显著较低，包括循环系统、呼吸系统和消化系统疾病。按就业时长、工资状况和化工生产部门对数据进行分析，未发现异常模式。该队列良好的死亡情况可能归因于员工选择性、健康维护、医疗可及性以及较少吸烟等因素。
