【摘要】 为探讨胃癌危险因素的致病作用 ,对 10 2例胃癌患者进行了 1∶1配对病例对照研究。在单因素条件Logistic回归分析中 ,慢性胃炎史、平时生活紧张、经常生闷气是胃癌发生的危险因素 ,饮茶和多食新鲜蔬菜则是胃癌的保护性因素。在多因素条件Logistic回归模型中 ,胃癌家庭史 (OR =2 .82 1)、慢性胃炎史 (OR =4.62 3 )和经常生闷气 (OR =1.80 7)是胃癌的危险因素 ,饮茶 (OR =0 .5 15 8)和多食新鲜蔬菜 (OR =0 .5 762 )则是保护性因素。更多还原

【Abstract】 Objective: To study the action of risk factors for gastric cancer.Methods:102 cases and 102 controls were analyzed by single conditional Logistic regression. Result: Having Chronic gastrtis,busy life,getting easily angry are the risk factors of gastric cancer.In the model of multivariate Logistic regression,the factors are having gastric cancer(OR=2.821),chronic gastritis (OR=4.623) and getting easily angry (OR=1.807), while drinking tea (OR=0.5158) and eating greens(OR=0.5762) are protective factors for gastric cancer.更多还原
