This study is aimed at assessing the prevalence of Helicobacter pylori infection, and the associated potentially factors, in a group of individuals that were examined 10 years ago in a district located in the East part of Minas Gerais State, Brazil, and still lived there. Structured questionnaires were used to explore the characteristics of 143 individuals. The detection of H. pylori was performed by Urea Breath test. The results showed that 70% (n = 100) of subjects were infected. It was noted that H. pylori infection is associated with the augment of age, individuals between 55 and 69 years of age had the highest probability of infection (OR: 43.33; CI: 4.97-378.00). Besides, individuals that lived with a partner (OR 2.80; 1.34 – 5.85), hypertensives (OR: 3.91, CI: 1.51-10.14) and who never went to school or had concluded elementary course (OR: 2.88, CI: 1.09-7.56; OR: 3.67, CI: 1.05-12.81, respectively) were also associated with infection. The possible improvements of socioeconomic status showed no protective effect in the acquisition of H. pylori infection. One can speculate that a longer period will be necessary so that the improvements in living conditions in this locality contribute to reducing the incidence of infection in the population.
Key words: Helicobacter pylori, infection, epidemiology, associated factors, urea breath test.
