Coffee is the second most popular drink worldwide, and it has various components with antioxidant and antitumor properties. Due to its chemical composition, it could act as an antitumor substance in the gastrointestinal tract. The objective of this study was to explore the relationship between coffee consumption and the incidence/mortality of stomach cancer in the highest-consuming countries. An ecological study using Spearman's correlation coefficient was performed. The WorldAtlas's dataset of coffee consumption and the incidence/mortality rates database of the International Agency for Research were used as sources of information. A total of 25 countries were entered to the study. There was an inverse linear correlation between coffee consumption in kg per person per year and estimated age-adjusted incidence ( = 0.5984, = 0.0016) and mortality ( = 0.5877, = 0.0020) of stomach cancer. Coffee may potentially have beneficial effects on the incidence and mortality of stomach cancer, as supported by the data from each country analyzed.
咖啡是全球第二大受欢迎的饮品，它含有多种具有抗氧化和抗肿瘤特性的成分。由于其化学组成，咖啡可能在胃肠道中起到抗肿瘤物质的作用。本研究的目的是探讨咖啡消费与最高消费国家胃癌发病率/死亡率之间的关系。采用斯皮尔曼相关系数进行了一项生态学研究。使用 WorldAtlas 的咖啡消费数据集和国际癌症研究机构的发病率/死亡率数据库作为信息来源。共有 25 个国家纳入研究。咖啡人均年消费量（以公斤计）与估计的年龄调整发病率（ = 0.5984， = 0.0016）和死亡率（ = 0.5877， = 0.0020）呈负线性相关。分析每个国家的数据均表明，咖啡可能对胃癌的发病率和死亡率有有益影响。
