Epidemiological, Clinical, and Diagnostic Aspects of Chronic Abdominal Pain in Children: A Study in Shahrekord, Iran

Background and aims: Due to the multi-factoriality of chronic abdominal pain (CAP) in children, this study aimed to assess the main etiologies for CAP in children and its main determinants in a sample of the community of affected children living in Shahrekord, Iran. Methods: This cross-sectional study was conducted on 400 children aged 3-14 years who were referred to a referral clinic in Shahrekord, Iran in 2022. Abdominal pain at least 3 times in 3 months, which disrupted daily activities, was the criterion for entering the study. A checklist was prospectively fulfilled by interviewing to assess different aimed data. Results: The majority of children complained of periumbilical pain as the main site of chronic pain, and other pain points were much less common. The main characteristics that provided grounds for suspecting this type of pain included right abdominal pain without clear justification, growth disorder, and severe vomiting. The most common definitive diagnosis was functional constipation, followed by chronic gastritis and fecal impaction. Conclusion: The occurrence of periumbilical pain, along with the occurrence of severe and frequent vomiting and growth failure can be considered diagnostic markers triad when suspecting the occurrence of CAP. The most common etiologies for such pains included functional constipation, chronic gastritis, and fecal impaction.
