胃癌死亡率与部分饮食因素的灰色关联分析

Grey Relational Analysis for Stomach Caner Mortality and Some Dietary Factors

本文对七个地区人均部分饮食每日消耗量与当地胃癌死亡率做了灰色关联分析,得到蔬菜(根叶茎)和胃癌死亡率的关联度最大,淡水鱼对胃癌死亡率关联度最小的结论,这就为胃癌亚硝胺病因假设提供了论据。

In this paper, using the method of grey relational analysis, we obtain the relations between the stomach caner mortality and some dieary factors in seven differednt areas. Our results obtained show that stomach caner moritality has relations with the roots, stems and leaves of vegetables. The relational degree is the biggest, and the relational degree of stomach caner morality and fresh fish is the smallest. So we arrive at the conclusion that the pathogeny of stomach caner is nitrosamine.
