采用以人群为基础的病例对照研究,探讨贲门部胃癌发病的危险因素。将病例与对照按1:3的比例配比,所有研究因素在Egret软件包上进行单因素和多因素条件Logistic分析。结果,单因素条件Logstic回归分析表明饮用非自来水、喜食干硬食物、有胃癌家族史与贲门癌发病呈显著正相关,多食新鲜蔬菜和饮茶与贲门癌发病呈显著负相关;多因素条件Logstic回归分析结果饮用水、食用新鲜蔬菜、饮茶、食干硬食物、生活紧张程度、经常生气、胃癌家族史等进入最终模型。有关贲门癌流行病学的研究有待于进一步的深入。
A population-based case-control study was conducted to investigate the risk factors for gastric cancer in the cardia. The case and the control were matched in a ratio of 1:3. All research factors were performed on the Egret software package by single-factor and multi-factor conditional logistic analysis. Results: Logistic regression analysis showed that there was a significant positive correlation between the family history of gastric cancer and the incidence of gastric cardia cancer. There was a significant negative correlation between the consumption of fresh vegetables and tea and the incidence of cardiac cancer. Conditional Logstic Regression Analysis Results Drinking water, eating fresh vegetables, drinking tea, eating hard dry foods, life stress, frequent anger, family history of gastric cancer, etc. entered the final model. Research on the epidemiology of cardiac cancer needs further study.
