title: Seroepidemiologic study of Helicobacter pylori infection in children in Taipei city.
abstract: To study the epidemiology of Helicobacter pylori (H. pylori) infection in children, the presence of the IgG antibody against H. pylori was evaluated by enzyme-linked immunosorbent assay (ELISA) method in unselected children in Taipei city. Serum samples were collected there from 428 apparently healthy children under 12 years of age. The overall prevalence of H. pylori infection was 8.4%. A low prevalence was found in the groups 1-3 years old (0.9%) and 3-6 years old (3.7%). The prevalence rate increased significantly after 6 years of age, and reached 19.4% at 9-12 years of age. In conclusion, H. pylori infection was independent of gender, but increased with age.
