Association between the high risk occupations and bladder cancer in Iran: A case-control study

The objective of this work was to identify the high-risk occupations in Iran and to re-inspect occupations that
were related to bladder cancer. Materials and Methods: In the study, 300 patients suffering from bladder cancer and 500
control individuals were interviewed. Demographic information, occupational history, and history of exposure to chemical
compounds such as aromatic amines for each participant were collected. ORs and 95% CIs were calculated using unconditional
logistic regression for each occupation. Results: There was a significantly increased risk of bladder cancer among
truck and bus drivers (OR = 11.3), skilled agricultural, forestry and fishery workers (OR = 6.0), metal industry workers
(OR = 6.0), domestic housekeepers (OR = 5.9), and construction workers (OR = 3.8). Conclusions: The study showed
a strong correlation between truck and bus drivers, skilled agricultural, forestry and fishery workers, metal industry workers,
domestic housekeepers, as well as construction workers and the increased risk of bladder cancer in these occupations.
