| 5 | Factors associated with H pylori epidemiology in symptomatic children in Buenos Aires,Argentina显示文摘AIM: To determine prevalence of H pylori infection in symptomatic children in Buenos Aires, Argentina, and to investigate factors associated with H pylori positivity. METHODS: A total of 395 children with upper gastrointestinal symptoms referred to the Gastroente-rology Unit of the Children Hospital “Sor Maria Ludovica” were evaluated for the presence of H pylori by the 13C-Urea Breath Test (13C-UBT). A questionnaire was applied to the recruited population.RESULTS: Prevalence of H pylori infection was 40.0%in this population (mean age 9.97 ± 3.1 years). The factors associated with H pylori positivity were number of siblings (P < 0.001), presence of pet cats (P = 0.03) and birds (P = 0.04) in the household, and antecedents of gastritis among family members (P = 0.01). After multivariate analysis, number of siblings [Odds ratio (OR) = 1.39; 95% CI, 1.20-1.61] and contact with pet cats (OR = 1.76; 95% CI, 1.00-3.09) remained as variables associated with H pylori infection. CONCLUSION: The prevalence of H pylori infection in children with upper gastrointestinal symptoms in Argentina was similar to that reported in developed countries. Children from families with a higher crowding index and presence of pet cats have a higher risk of being colonized with H pylori. | Cinthia Goldman Andrés Barrado Mariana Janjetic Norma Balcarce Eduardo Cueto Rua Masaru Oshiro María L Calcagno Margarita Martinez Sarrasague Julián Fuda Ricardo Weill Marcela Zubillaga Guillermo I Perez-Perez José Boccio | 2006 | World Journal of Gastroenterology2006，12，33： | 0 |
