The aim of the present study was to estimate incidence and spontaneous clearance rate Helicobacter pylori infection effect some variables on these outcomes in schoolchildren.From May 2005 December 2010, 718 schoolchildren enrolled 3 public boarding schools Mexico City participated follow-up. At beginning every 6 months thereafter, breath samples were taken detect H infection; blood anthropometric measurements evaluate nutritional status. Data sociodemographic characteristics collected.The prevalence 38%. 6.36%/year. Schoolchildren with anemia or iron deficiency at (who received supplements) showed a higher acquisition than those normal status, hazard ratio (HR) 12.52 (95% confidence interval [CI] 4.01%-39.12%), P < 0.001 HR 2.05 CI 1.09%-3.87%), = 0.027, respectively. 4.74%/year. children who had supplements), 5.02 1.33%-18.99%), 0.017, compared It lower ≥ 2 siblings 1 no siblings, 0.23 0.08%-0.63%), 0.004.H status is dynamic schoolchildren. Variables related health transmission, such as number are important for infection.
