title: [Case-control study on the correlation of bladder cancer incidence and occupational factors].
abstract: OBJECTIVE
  To explore the relationship between occupational factors and the incidence of bladder cancer.
  
  
  METHODS
  The present research was based on a hospital-based case-control study. The cases were frequency matched. The non-conditional Logistic regression was used to calculate the odds ratio (OR) of each occupation.
  
  
  RESULTS
  The OR of business and administration professionals, male electricians and electronic workers were 3.88 and 7.40; the OR of janitors and helpers was 0.21; the OR of handcrafted and printing clerks was 0.71, but there was no significant difference.
  
  
  CONCLUSIONS
  Business and administration professionals, male electricians and electronic workers tend to have bladder cancer. The occupation of janitors and helpers has a protective effect on bladder cancer while the occupation of printing clerks shows no statistical significance on bladder cancer.
