Abstract

Introduction: within the last decades, great importance has been given to the bacterium Helicobacter Pylori. The Helicobacter pylori infection is a public health problem and is recognized as one of the most common chronic infections, estimating that about half of the world’s population is infected with it. This bacterium, located in the gastric mucosa, is related to some pathologies: gastritis, gastric carcinoma, peptic ulcer. Methods: We carried out an observational cross-sectional study with a community sample of adults from the municipalities of Viseu and Satão. The final sample consisted of 166 adults, aged between 19 and 92 years (mean of 46.96 ± 3.17 years), and the majority female (56.6%). Data were collected through a self-administered questionnaire with questions regarding sociodemographic aspects, the family household and daily habits and lifestyles. The H. pylori infection was identified using the urea breath test. The test was performed in the morning after at least 6 hours of fasting. Statistical analysis was performed using the statistical program SPSS 23.0. The prevalences were expressed in proportions and compared by the chi-square test with a level of significance of 0.05. Associations were calculated using the Odds Ratio (OR), with 95% confidence intervals (95% CI). Results: The prevalence of Helicobacter Pylori was 48.8% (50.0% in females and 47.2% in males). We found higher percentages in the female gender, for ages ≤ 50 years, married, with an education level inferior to 12th grade, with a greater number of siblings, and for those who were employed. Nonetheless, the differences were not statistically significant. Conclusion: Almost half of the sample was infected by the Helicobacter pylori bacteria. We found no association between the presence of Helicobacter pylori and gender; age; marital status; schooling, body mass index, professional situation, number of household members and the number of rooms
