[Prevalence of Infantile Colic: Experience of the Working Group on Disorders of Gut-Brain Axis of the Latin American Society of Paediatric Gastroenterology, Hepatology and Nutrition (LASPGHAN)].

Introduction: The prevalence of infantile colic in Colombian children is 10.4% according to Rome III criteria. Aim: To determine the prevalence of infantile colic in Latin American children (Latam) according to Rome IV criteria and its possible associations. Materials and methods: Observational, descriptive, and cross-sectional study conducted in two South American and five Central American countries. From the Functional International Digestive Epidemiological Research Survey database, we included children under 5 months of age who were diagnosed with infantile colic through the Questionnaire Pediatric Gastrointestinal Symptoms Rome IV. Results. We analyzed 633 infants (74.4% from South America, 2.3 ± 1.1 months of age). Infantile colic was diagnosed in 7.4% (61.7% male; 59.6% mestizo; 38.3% Colombian); being more frequent in the first month of life and in those born by caesarean section, in 27.7% of preterm infants, 10.6% of those fed with human milk and 4.3% with separated parents. A higher chance for infantile was found colic in mestizos (OR = 1.86 CI95% = 0.97-3.60 p = 0.0416) and in the presence of intrafamilial gutbrain axis disorders (OR = 4.24 CI95% = 1.15-12.85 p = 0.0036). Living with both parents was a protective factor (OR = 0.23 CI95% = 0.02-0.94 p = 0.0336). Conclusion: The prevalence of infantile colic in Latam children, of 7.4%, was lower than that described by Rome III. An association was found with intrafamilial gut-brain disorders and mestizos. Living with both parents was a protective factor.
