Our aim was to determine the prevalence of FGIDs among children and adolescents in Argentina using the Rome III diagnostic criteria. Materials and methods: A total of 483 children, 12-18 years of age, from 3 private schools and 3 public schools, were included in the study. Each child completed the Spanish version of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III), which is an age-appropriate and previously validated instrument for diagnosing FGIDs according to the Rome III criteria. Sociodemographic data (age, sex, type of school, family structure and size, family history of gastrointestinal disorders) and data on stressful life events were also obtained. Results: The mean age of the population studied was 15 years (standard deviation 1.74, range 12-18, 52.8% boys). Of the respondents, 229 children (47.4%) attended private school and 254 children (52.6%) attended public school. In total, 82 children (17.0%) were diagnosed with an FGID, according to the Rome III criteria. Abdominal migraine (16.4%) was the most com- mon diagnosis, followed by irritable bowel syndrome (7.0%), functional constipation (6.4%), and aerophagia (5.6%). Girls suffered significantly more from FGIDs than boys (22.4 vs. 12.2%,  Please cite this article as: Nelissen LG, Koppen IJN, Follett FR, Boggio-Marzet C, Saps M, Garzon K, Benninga MA.
