شیوع عفونت هلیکوباکترپیلوری در کودکان بدون علامت 9-15 سال شهر بیرجند

Background and Aim: Gastrointestinal disease is one of the most common infectious diseases in the world. One of the most important causes is Helicobacter pylori infection. Considering the importance of this bacterium and its different prevalence in different parts of the country, this study was conducted to determine the prevalence of Helicobacter pylori infection and its related factors in 9-15 year old asymptomatic children in Birjand city. Materials and Methods: This descriptive cross-sectional study was conducted on 332 children aged 9 to 15 years old in Birjand, &nbsp;in 1395. Individuals who had inclusion criteria were selected by multi-stage sampling. The demographic profile including age, sex, duration of breastfeeding, number of households, and number of yoghurt consumption per week, were completed for children. Helicobacter pylori stool antigen test was used in feces to evaluate Helicobacter pylori infection. Data were analyzed using Chi-square and Fisher's exact test at a significant level of 0.05. Results: Of the 332 children studied, 59 (17.8%) children had Helicobacter pylori infection. Our results showed no significant relationship between sex and duration of lactation with Helicobacter pylori infection (p> 0.05). However, with increasing age and number of family members, Helicobacter pylori infection was significantly increased (p <0.05). By increasing the consumption of yogurt per week, Helicobacter pylori infection was significantly reduced (p = 0.02). Conclusion: Due to the &nbsp;prevalence of &nbsp;Helicobacter pylori infection and less frequently in dairy consumers should be given the necessary training for families.
