Seroprevalence, risk factors and comorbidities associated with Helicobacter pylori infection amongst children receiving care at Kilimanjaro Christian Medical Center

Background: Helicobacter pylori frequently causes gastritis and peptic ulcers, and affected children are at risk of developing gastric carcinoma later in adulthood. Methods: This was a Hospital based cross sectional study. A total of 200 children aged 6 months to 14 years were enrolled. Study subjects were tested for H. pylori using a standard serology rapid test measuring immunoglobulin G for H. pylori. For risk factors, Chi-square tests were used to test for association and then, odds ratios and their corresponding 95% confidence intervals and p-values were computed using logistic regression. Results: The overall seroprevalence of H. pylori was 11.5%. The following factors were associated with H. pylori infection: Age group above 10 years, keeping a dog and household size. The independent predictors of H. pylori were: Fathers\u2019 occupation, keeping a dog, indoor tap water, age group, household size and diabetes mellitus type 1.. Conclusion: The seroprevalence of H. pylori antibodies was lower compared to most developing countries. Keeping a dog, household size, indoor tap water, fathers\u2019 occupation and diabetes mellitus type 1 were found to be independent predictors of presence of H. pylori antibodies
