Methods For epidemical survey, 199 gastric cancer patients were randomly selected from the residents of Cixi city for 1∶1 frequency-matched case control study. The relationships between gastric cancer and risk factors were estimated by conditional Logistic regression models. Results Increased risks of gastric cancer were associated with the history of gastric ulcer disease(OR=18.04, 95%CI:3.94-82.56), A-type characteristics(OR=2.26, 95%CI:1.45-3.55), and poor ability in self-regulation of mood(OR=2.63, 95%CI:1.00-6.91). Conclusion History of gastric ulcer disease, A-type characteristics and poor ability in self-regulation of mood partially contribute to the incidence of gastric cancer in the residents of Cixi.
