Abstract
Objective
To investigate whether urban bus drivers are at increased risk for cancer.
Methods
Urban bus drivers in a cohort established in 1978 in the three largest cities of Denmark were followed‐up in the Danish Cancer Registry until the end of 2003, and relative risks for cancers were estimated.
Results
Of 2,037 men included 70% reported in 1978 that they smoked. The standardized incidence ratio (SIR) for cancer in comparison with that of other male residents of the three cities was 1.09 [1.0–1.2]. The excess was due mainly to increased risks for cancers of the bladder (SIR, 1.6; 1.2–2.0) and lung (1.2; 1.0–1.4). In an analysis with internal comparisons and adjustment for smoking, we found no significant associations between duration of employment and increased risks for cancers at these two sites.
Conclusions
In this long‐term follow‐up study we found little evidence of a causal association between employment as an urban bus driver in Denmark and subsequent cancer. Am. J. Ind. Med. 53:757–761, 2010. © 2010 Wiley‐Liss, Inc.
