Functional gastrointestinal disorders, quality of life, and behaviour in adolescents with history of infant colic.

Aim: To assess the prevalence of functional gastrointestinal disorders (FGIDs), health-related quality of life (HRQOL), and behavioural problems in a cohort of adolescents with a history of infant colic (IC), as defined by Wessel's criteria.

Methods: 388 adolescents, aged 15-18 years, who participated in a randomised controlled trial for infants with colic, were invited for our observational follow-up study. Prevalence of FGIDs was assessed with the Rome IV Questionnaire on Paediatric Gastrointestinal Disorders (RIV-QPGD), HRQOL through self-report of the Paediatric Quality of Life Inventory (PedsQL), and behavioural problems through parent-report of the child behaviour checklist (CBCL). Multivariable models were used to compare prevalence rates of FGIDs and HRQOL scores.

Results: 190 (49%) adolescents with a history of IC (cases) and 381 controls were included (median age 17.0 [IQR 16.0-17.0] and 16.0 [15.0-17.0] years, respectively). Cases had a significantly higher risk for postprandial distress syndrome compared to controls (aOR 2.49 (95%CI 1.18-5.25), p = 0.002). After multivariable regression, total, physical and school HRQOL scores were significantly lower in cases compared to controls (p = 0.003, 0.001, and 0.009).

Conclusion: Adolescents with a history of IC demonstrate higher prevalence rates of postprandial distress syndrome compared to controls. However, conclusions should be made with caution due to attrition and information bias.
