To detect the risk factors for stomach cancer, we performed correlation analyses among stomach cancer mortality, food consumption, and other related factors using population-based data. Cereals (especially rice) and salty foods (particularly salted and dried fish) were related positively to stomach cancer mortality; milk and milk products, meat, oils and fats, and fruits were related inversely to it. We believe these results show that factors related positively to stomach cancer mortality could play a role in risk and those related inversely could be protective in the etiology of stomach cancer. As complementary methods in case-control and cohort studies, correlation analyses seemed useful when variation of exposures to risk factors is small between individuals within a population but is relatively large between populations.
为了检测胃癌的风险因素，我们使用基于人群的数据，对胃癌死亡率、食物消费及其他相关因素进行了相关性分析。谷类（尤其是大米）和咸味食品（特别是咸鱼和鱼干）与胃癌死亡率呈正相关；牛奶及奶制品、肉类、油脂和水果与胃癌死亡率呈负相关。我们认为，这些结果表明，与胃癌死亡率呈正相关的因素可能在风险方面起作用，而呈负相关的因素在胃癌病因学中可能具有保护作用。作为病例对照研究和队列研究的补充方法，当人群中个体之间风险因素暴露的差异较小但人群之间差异相对较大时，相关性分析似乎是有用的。
