The data came from an occupational cohort study of arsenic (7440382) and lung cancer. The cohort consisted of all white male workers employed for 1 year or more between 1940 and 1964 at a copper smelter in Tacoma, Washington. After controlling for the level of current exposure, age at hire and year at hire, the risk of having a 30 day or longer absence was generally higher with increased level of cumulative exposure. In contrast, current exposure level shows an inverse relationship with absence. The mortality analysis suggests that a recent absence of more than 30 days was associated with a higher risk of death from respiratory cancer among employees exposed to arsenic. The authors caution that information on absenteeism without knowledge of the reasons for the absence is not in and of itself in such studies. 收起
