Abstract Background and Aim We aimed to evaluate endoscopic findings of Helicobacter pylori (H. pylori)‐positive children and young adults based on the Kyoto classification, and to examine if there are age‐associated changes in H. pylori‐positive gastritis. Methods H. pylori‐positive patients under 40 years old who underwent upper gastrointestinal endoscopy from 1 April 2009 to 15 February 2017 were included. Subjects were classified into the Pediatric (65% in patients over age 25. Conclusion H. pylori‐positive children had endoscopic findings besides nodularity based on the Kyoto classification. The prevalence of atrophy increased in patients over age 20.
