目的:探讨河南农村地区胃癌发生的危险因素。方法:确定胃癌病例家系和对照家系各325户,每组1010人,以家庭为单位入户面访方式收集人群资料。应用单因素和多因素非条件logistic回归分析探讨不同因素对胃癌发病的影响。结果:胃不适症状、暴饮暴食、口味重、吃剩饭>3次/周、精神刺激史等因素在病例家系与对照家系的分布中差异具有统计学意义。结论:胃不适症状、暴饮暴食、口味重、吃剩饭>3次/周、精神刺激史等因素是病例家系成员发生胃癌的危险因素。
Objective: To investigate the risk factors of gastric cancer in Henan rural areas. Methods: To determine the 325 cases of familial and colorectal cancer patients with 1010 cases in each group, collect the crowd data by household interview. Univariate and multivariate non-conditional logistic regression analysis were used to explore the influence of different factors on the incidence of gastric cancer. Results: There were statistically significant differences in the distribution of cases of familial and control pedigrees with symptoms of stomach upset, overeating, heavy taste, leftover meals> 3 times / week, history of mental stimulation and so on. Conclusion: Stomach symptoms, overeating, heavy taste, leftover food> 3 times / week, history of mental stimulation and other factors are the risk factors of gastric cancer in family members.
