2000-2003年住院病人胃癌相关危险因素研究

目的了解住院胃癌病人饮食习惯、疾病史、不良嗜好等因素与胃癌危险性的关系。方法收集黑龙江省肿瘤医院2000--2003年经病理诊断的胃癌病人，共209例，进行病例对照研究。应用非条件logistic回归分析。结果吸烟、饮酒增加胃癌危险性。胃慢性疾病史、不良饮食习惯、嗜成与胃癌关系密切。情绪较差、性情急躁胃癌危险增加250％（OR=3．50，95％CI=1．95-6．24）。近年精神压抑可增加胃癌危险466％（OR=5．66，95％CI=3．68-8．94）。多食用葱、蒜类食品可降低胃癌危险性48．9％。结论胃慢性疾病史、不良饮食习惯及某些精神神经因素，肿瘤家族史等与胃癌有明显关系。多食用葱蒜类食品对胃癌的发生有保护作用。

A case control study on risk factors and gastric carcinoma of hospital patients from 2000 to 2003
