１９９４年２月２８日～４月２日间选择作胃内镜检查者９１例，年龄为２１～７３岁，其中男性５４例，女性３７例。以涂片镜检阳性作为诊断幽门螺旋菌（ＨＰ）感染的标准，对有关生活习惯、社会经济卫生情况等１３个变量进行多因素非条件Ｌｏｇｉｓｔｉｃ回归分析。结果表明：变量全部进入非条件Ｌｏｇｉｓｔｉｃ回归模型，用最大似然分析法作多因素逐步Ｌｏｇｉｔｉｃ回归分析，在分别平衡其余１２个变量的条件下，判定每个变量与ＨＰ镜检阳性相关性联系的意义，与单因素分析一样亦得出文化程度与家中是否饲养动物两变量的回归系数β值有显著性差异，结果未提示两者有交互作用。而感染情况与一般认为与胃炎有关的吸烟、饮酒、辛辣食物等生活习惯无关，提示它们很可能是互相独立的致病因素。这对进一步在一般人群中的深入研究具有一定的参考价值。
From February 28, 1994 to April 2, 91 patients underwent gastroscopy, ranging in age from 21 to 73 years, including 54 males and 37 females. Positive smear microscopy as a diagnostic criteria for Helicobacter pylori (HP) infection, 13 lifestyle variables related to living habits, socio-economic health conditions by multivariate non-conditional Logistic regression analysis. The results showed that all the variables entered the non-conditional Logistic regression model, and the maximum likelihood analysis was used for Logistic regression analysis of multiple factors. Under the condition of balancing the other 12 variables respectively, In the same way, univariate analysis also showed that there was a significant difference in the regression coefficient β between the education level and the two variables of domestic animals, but the results did not suggest the interaction between the two. The infection is generally not related to gastritis and smoking, drinking, spicy food and other habits has nothing to do, suggesting that they are likely to be independent of each other risk factors. This has further reference value for further research in the general population.
