[Screening results and influencing factors of upper gastrointestinal carcinoma and precancerous lesions in Feicheng City].

Objective: To clarify the situation of the detection of upper gastrointestinal cancer and precancerous lesions in the Feicheng city and discuss the possible influencing factors. Methods: A cluster sampling method was used to determine the participants. A unified questionnaire was used to investigate the basic information including history of alcohol intake, smoking and chinese tea, as well as other eating habits, medical history of digestive tract and cancer. Endoscopy was used to to screen the patients with upper gastrointestinal cancer and precancerous lesions. Influential factors were explored by non-conditional logistic regression model. Results: 911 of 7 291participants were positive, and the total detection rate was 12.49%. The total positive detection rate of male and female was 17.94% and 8.71%, respectively ( P <0.001). Multivariate logistic regression analysis showed that the sex ( OR =0.527, 95% CI : 0.440-0.631), age ( OR =2.037, 95% CI : 1.849-2.245), smoking ( OR =1.240, 95% CI : 1.014-1.516) and alcohol consumption ( OR =1.232, 95% CI : 1.012-1.500) , meat and protein intake ( OR =0.794, 95% CI : 0.638-0.987) and drink tea ( OR =1.233, 95% CI : 1.056-1.440) may be influencing factors of the total detection rate of upper gastrointestinal cancer and precancerosis. Conclusions: In Feicheng city, intake of meat and protein is the protective factor of the upper gastrointestinal cancer and precancerous lesions. Men, aged, smoking, drinking and tea will increase the risk of upper gastrointestinal cancer and precancerous lesions.
