The objective of this study was to determine the seroprevalence of Helicobacter pylori and associated factors in schoolchildren from Educational Institution No. 0026 in Ate (Lima) in December 2011. A prospective, cross-sectional, observational, and descriptive study was conducted in a sample of 106 children, aged 6 to 11 years, randomly selected and of both sexes. Data were collected using an epidemiological form and analyzed with SPSS version 20.0 and Microsoft Excel. The qualitative detection of IgG antibodies against Helicobacter pylori was carried out using a chromatographic immunoassay on whole blood obtained by direct finger prick. The results revealed a seroprevalence of 67% for Helicobacter pylori infection. The prevalence increased with age but was not related to gender. Significant associations were found between seroprevalence and lack of water and sewage services at home, poor handwashing habits, and having parents with gastroduodenal diseases. In contrast, sharing a bedroom and low hematocrit levels showed no association with infection. It is concluded that there is a high seroprevalence of Helicobacter pylori infection in this school population. The prevalence increases with age, reaching high levels within the first decade of life, with no differences between sexes. Furthermore, risk factors associated with the infection include poor hygiene practices, lack of basic sanitation, and the presence of gastroduodenal diseases in cohabiting family members.
