BACKGROUND: This study was conducted to determine characters and risk factors of Helicobacter pylori infection and its relationship with recurrent abdominal pain and other gastrointestinal symptoms at the main children's intermediate school in Rabigh, Saudi Arabia. METHODS: A cross-sectional study was conducted at a boys' intermediate school. A questionnaire for the gastrointestinal (GI) symptoms and relevant personal and socioeconomic risk factors related to H. pylori infection was distributed followed by H. pylori IgG antibody assay and 14C urea breath test to detect active infection. RESULTS: H. pylori was diagnosed by positive urea breath test in 51.5 % of students. H. pylori infection was symptomatic with at least one upper GI symptom in 89.7 % of infected students which was higher than symptomatic cases reported in any other study. H. pylori-infected students had significantly more association with the presence of any upper GI symptom (p < 0.001), recurrent abdominal pain (p < 0.001), anorexia (p < 0.001), nausea (p < 0.026), family history of peptic disease (p < 0.001), drinking desalinated municipal water (p < 0.001), lower income (p = 0.02), and eating outside home (p = 0.003) than uninfected students. Logistic regression analysis showed that the most significant predictors of H. pylori infection were presence of any upper GI symptom (OR 5.3, 95 % CI 2.32-15.71), family history of peptic disease (OR 2.2, 95 % CI 1.11-3.9), and drinking desalinated municipal water (OR 2.1, 95 % CI 1.09-3.2). CONCLUSIONS: This study presented unique features and risk factors of H. pylori infection in 12-15-year-old Saudi boys in Rabigh, and mainly supported the role of H. pylori in causing recurrent abdominal pain.
