The highest infection rate was observed in the 22-23 age group (54.5%). Clinical symptoms such as abdominal pain (p = 0.010) and nausea or vomiting (p = 0.026) were significantly associated with infection. A history of previous diagnosis (p < 0.001) and treatment (p < 0.001) was also strongly correlated with a positive test result. However, no significant associations were found between infection and other factors such as dietary habits, hygiene practices, or smoking. CONCLUSIONS: The findings indicate a relatively high prevalence of H. pylori infection among medical students at Shendi University. These results highlight the need for targeted awareness campaigns and improved preventive strategies within this population.
