Odds ratio (OR) of various factors and their 95% confidence Iimites and X~2 value was calculated. Weighted logistic method analysis was done to six risk factors. It's found that the CAG is closely related to family history of gastric diseases, irregular time for meals, taking meal quickly, eating fried foods, melancholy and chronic inflammation of the mouth, nose, and throat.The OR of these factors are :3.58, 5.83, 3.73, 3.5 and 3.0(P<0.001) respectively.
