The cross-sectional descriptive study included 1176 children between the ages of 4 and 9 who applied for Family Medicine Centers between March 1, 2017 and April 30, 2017 for various reasons. Pediatric Gastrointestinal Symptoms Questionnaire, Roma III Version (QPGS-RIII) was applied to the volunteers (children’s parents or caregivers), and Beck Anxiety Scale was applied to the mothers accompanying their children. A total of 603 (51.9%) of the children included in the study were female and 559 (48.1%) were male. When the applied QPGS-RIII was evaluated with IBS diagnostic criteria, IBS was found in 137 children and IBS frequency was found to be 11.8% (95% confidence interval [CI]). Significant differences were found in socioeconomic level, eating habits, TV-watching habits, and IBS status (P <.05). © The Author(s) 2023.eninfo:eu-repo/semantics/openAccessIBSpediatricsprevalenceprimary careArticle10.1177/000992282312044552-s2.0-85173912594
