Prevalence and risk factors of Helicobacter pylori infection in healthy schoolchildren

OBJECTIVE:  Data regarding the prevalence of Helicobacter pylori infection and its potential risk factors among schoolchildren from the Middle East is scarce. METHODS:  An enzyme‐linked immunosorbent assay was used to investigate H. pylori status in four groups of children: The first and second grou...

description OBJECTIVE:  Data regarding the prevalence of Helicobacter pylori infection and its potential risk factors among schoolchildren from the Middle East is scarce. METHODS:  An enzyme‐linked immunosorbent assay was used to investigate H. pylori status in four groups of children: The first and second groups, 50 children each (25 boys, 25 girls) included children from high socioeconomic class (group 1 = 6 years old; group 2 = 9 years old). The third and fourth groups were sex‐ and age‐matched, but from low socioeconomic class. To evaluate the association between the seroprevalence of H. pylori and selected risk factors, odds ratios (crude and adjusted) were calculated using multiple regression analysis. RESULTS:  Overall seroprevalence rate was 55.5%. Seropositivity was 42%, 52%, 60%, and 68% for groups 1, 2, 3, and 4, respectively. Age and sex were not significantly associated with H. pylori seropositivity. In the final logistic regression model, which was adjusted for age and sex, the following risk factors were found to be significantly associated with seropositivity: living in rural areas (P = 0.015), poor sanitation (P
