infected by H. pylori and15% were diabetic. The prevalence of H. pylori infection in diabetics was higher among participants with incomplete high school at 83%, non-smokers 64% and non-drinkers 55%, though not significantly different. There was a positive relationship between coffee consumption and H. pylori infection. In the two-sample proportion test, a higher proportion of hpx+ diabetic individuals was found among coffee consumers with 45%, when compared to hpx-diabetics (27%), though with no significant difference (p=0.285). In this study, there was no significant association between H. pylori infection and DM. New trials with a larger sample size would be useful to elucidate a possible association between H. pylori infection and DM, as well as the pathological mechanisms of the bacteria that are involved in the development of DM.
