Area of Science:

  • Pediatrics
  • Gastroenterology
  • Epidemiology

Background:

  • Cyclical vomiting syndrome (CVS) is a disorder characterized by recurrent episodes of intense nausea and vomiting.
  • Understanding the prevalence and clinical features of CVS in children is crucial for diagnosis and management.

Purpose of the Study:

  • To determine the prevalence of cyclical vomiting syndrome (CVS) in a defined childhood population.
  • To characterize the clinical features, associated conditions, and triggers of CVS in children.

Main Methods:

  • A questionnaire-based screening was conducted on 2,165 children aged 5-15 years in Aberdeen.
  • Symptomatic children underwent clinical interviews to diagnose CVS based on established criteria.
  • Prevalence rates and clinical characteristics were analyzed.

Main Results:

  • The prevalence of CVS was found to be 1.9% (34 out of 1,830 children evaluated).
  • Children with CVS had a mean age of 9.6 years, with symptom onset around 5.3 years.
  • Associated conditions included migraine (21%), travel sickness (29%), and atopic diseases (29%). Attacks averaged 8 per year, lasting 20 hours, often triggered by travel.

Conclusions:

  • CVS has a significant prevalence in childhood populations.
  • Clinical features of CVS overlap with migraine, suggesting a potential common underlying pathogenesis.
  • Identifying triggers and associated conditions aids in understanding and managing CVS in children.
