目的 探讨饮食及其他生活习惯与胃癌发生的关系。方法1999年1～12月,在胃癌高发区福建省长乐市,收集了310例胃癌新发病例,每个病例配一个同年龄组与性别的对照。调整相对危险度(OR)及其95％可信区间(CI)的估计采用条件Logistic回归。结果 随食用盐渍食品的增加,胃癌的发病危险度亦随之增加(经常与从不吃,OR=2.55,95％ CI=1.04～6.29,趋势检验,P=0.01)。喜烫食、硬食及重盐亦可增加胃癌的发病危险,反之多食禽蛋、新鲜水果、大蒜对胃癌有保护作用。未见食用新鲜蔬菜、吸烟、饮酒、饮茶、冰箱使用与胃癌的关系。结论 食用盐渍食品、喜烫食、硬食及过量摄入食盐可能是胃癌的危险因素,而禽蛋、新鲜水果、大蒜类蔬菜则可能对胃癌有保护作用。
Objective To explore the relationship between diet and other habits and the occurrence of gastric cancer. Methods From January to December 1999, 310 newly diagnosed cases of gastric cancer were collected in Changle City, Fujian Province, with high prevalence of gastric cancer. Each case was matched with the same age group and gender. Adjusted adjusted for relative risk (OR) and 95% confidence interval (CI) were estimated using conditional logistic regression. Results With the increase of salted food, the risk of gastric cancer also increased (often and never eat, OR = 2.55, 95% CI = 1.04 ~ 6.29, trend test, P = 0.01). Hi hot food, hard food and heavy salt can also increase the risk of gastric cancer, conversely, eat more eggs, fresh fruits, garlic have a protective effect on gastric cancer. No consumption of fresh vegetables, smoking, drinking, drinking tea, the use of refrigerators and gastric cancer. Conclusion Edible salted foods, hi-hot foods, hard foods and over-intake of salt may be risk factors for gastric cancer. Eggs, fresh fruits and garlic-based vegetables may have a protective effect on gastric cancer.
