ABSTRACT
<p><b>OBJECTIVE</b>To explore the application value of correspondence analysis in ecological study.</p><p><b>METHODS</b>We adopted correspondence analysis method to analyze the relationship between the amount of food intake in some cities in China and the male gastric carcinoma mortality.</p><p><b>RESULTS</b>According to scatter plots of row and column points, there were regional differences among the male gastric carcinoma mortality in different cities of China.</p><p><b>CONCLUSION</b>The scatter plot of row and column points indicated directly that there were regional differences among the male gastric carcinoma mortality in different cities of China. Males from the Southern part of the country ate more rice and salt, less wheaten food and fewer light vegetables than those from the northern parts, suggesting that there might be some carcinogenic factors in some food stuff involved.</p>
