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.[SDGs]SDG3bacterium antibody; article; child; enzyme linked immunosorbent assay; epidemiology; female; Helicobacter infection; Helicobacter pylori; human; immunology; infant; male; preschool child; prevalence; Taiwan; Antibodies, Bacterial; Child; Child, Preschool; Enzyme-Linked Immunosorbent Assay; Female; Helicobacter Infections; Helicobacter pylori; Humans; Infant; Male; Prevalence; Seroepidemiologic Studies; Taiwanjournal article75721662-s2.0-0029335366
