The prevalence of functional gastrointestinal disorders (FGIDs) in children in Ecuador is unknown. We describe a survey study in 2 schools in Quito, Ecuador, using a Spanish translation of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version (QPGS-RIII). A total of 417 children (51% boys) with a mean age of 12.0 years were included. FGIDs were present in 95 children (22.8%) and occurred in 25% of girls and in 20.7% of boys (P = 0.296). Functional defecation disorders were found in 12.0% of children, 9.4% had an abdominal pain-related FGID and 3.8% was diagnosed with a vomiting or aerophagia FGID.
