    Abstract:
    The aim of this study was to evaluate the role of breastfeeding and the infection status of the mother in the acquisition of Helicobacter pylori infection in a poor urban community in northeastern Brazil. Helicobacter pylori status was evaluated by 13C-urea breath test in individuals under the age of 14 years and by ELISA in the mothers. The prevalence of H. pylori infection was 55.8% (197/353) in the children and it increased with age (P<0.0001). Of the children in whom breastfeeding status was known, 93.2% (316/339) were breastfed. The H. pylori prevalence did not differ between breastfed and never breastfed children (55% vs. 52%) even when children were breastfed for >6 months. The prevalence of infection was much higher in children whose mothers were H. pylori infected than in children whose mothers were not infected, resulting in a crude odds ratio (OR) of 3.11 (95% CI 1.57-6.19) and 2.40 after adjustment for potential confounders (95% CI 1.12-5.15). This study suggests that breastfeeding does not protect against acquisition of H. pylori in northeastern Brazil; conversely, an infected mother may have an important role in transmission of the disease to the child.
