Background: Helicobacter pylori (H. pylori) is a small, spiral-shaped bacterium that lives in the surface of the stomach and duodenum. More than half of the world’s population is colonized with H. pylori in the gastric mucosa which is the major cause of chronic gastritis, peptic ulcer and also the most important etiological factor responsible for the duodenal and gastric ulcer and has an important role in the pathogenesis leading to gastric cancer. Objectives: The objectives of this study was to determine the prevalence of H. pylori among gastritis patients at Nemba district hospital, to compare sex prevalence level of H. pylori among gastritis patients and determine the prevalence of H. pylori among gastritis patients according to the age of gastritis patients. Methods: This study involved 140 patients with gastritis who attended Nemba district hospital from August to October 2018. The samples were collected and H. pylori rapid test strip was performed for all patients to diagnose H. pylori among gastritis patients. Results: Findings of the study showed that the prevalence of H. pylori infection was found to be significantly high among female participants than male participants. Despite high prevalence in females, the findings showed that there was no statistical significance of sex with H. pylori infection (χ2 = 0.6 and p > 0.05, p = 0.1). On basis of age, the prevalence of H. pylori infection was found to be high among participants and the prevalence increase between young age and old age. Results show that there was statistical significance between age and H. pylori infection with χ2 = 1.2 and p > 0.05, p = 0.04. the group of individuals with that ≥ 45 years old were more affected compared to other age groups and the prevalence of H. pylori infection was increased in older patients than younger patients. Our study showed an overall prevalence of H. pylori among gastritis patients was (45.7% n = 140). Conclusion: H. pylori infection is terrible burden of public health and affect people of all age and sex. H. pylori infection was significantly high in females and significance was found in age group of patients. Number of people are carrier of this terrible bacterium, thus hospitals are recommended to carry out early diagnosis to avoid later complication of infection.
