Abstract

ABSTRACT

The objective of this study was to determine the seroprevalence of Helicobacter pylori infection in Itapeuá, Municipality of Coari, in the rural area of Amazonas State, Brazil. A seroprevalence of 82% was observed in a sample of 100 individuals examined. The infection rate verified in children and adolescents (53%; 44/82) was higher than in adults and elderly (47%; 39/82). Stratified sampling of the population in age intervals of ten years showed that the age group 11-20 presented the highest frequency level (31%) and the highest infection rate (90%; 28/31). This association was relevant (G-test = 16.9312, p = 0.0095), and the prevalence of infection among male adults and female children (G-test = 9.8576, p = 0.0072) showed that individuals in these age groups are more susceptible to this bacterial infection.
