Abstract
Helicobacter pylori (H. pylori) infection is more prevalent in low- and middle-income countries. This research aimed to identify the main risk factors and the role of the family in its transmission. A cross-sectional institutional study was conducted in 165 children under 19 years of age and 502 cohabitants, who were tested for H. pylori. All candidate variables were entered into a multivariate logistic regression. 43.6% of children under 19 years of age and 27.4% of cohabitants were infected. The main risk factors identified were living in a rural area and having an infected cohabitant; among these, infected siblings and grandparents were the most frequent. In this selected group of patients, the family environment and living in a rural area seem to be the main risk factors for transmission.
