ABSTRACT
Background:
A 73% prevalence of Helicobacter pylori infection was estimated in adults in the 2003 Chilean National Health Survey. However, this infection is usually acquired during childhood.Aim:
To determine the frequency of H. pylori infection in healthy Chilean children from a school in Santiago. Material andMethods:
A cross sectional study in a private/ subsidized school in Santiago. Children aged less than 18 years were invited to participate. The parents of those who accepted answered a demographic survey and a stool sample was obtained from participants to detect H. pylori antigen using a monoclonal antibody ELISA kit.Results:
We studied 144 students aged 10.6 ± 3.1 years (54% females). Twenty six participants (18.1%, 95% CI 12.4-24.9%) had a positive test. Children from higher socioeconomic levels had a non-significant lower frequency of infection. No differences in the frequency of infection were observed by age, gender, household type or number of people living in it or history of breastfeeding.Conclusions:
In this sample of children, an 18.1% frequency of H. pylori infection was observed.
