A novel population-based UK study by Cooney and colleagues (OP 28) examined the association of IBD and various mental health disorders such as depression, anxiety and self-harm in children and adolescents. A large primary care database was used to identify cases. Each case was propensity matched with four controls. Relative risk of all outcomes up to 10 years in the IBD cohort versus controls was estimated using adjusted Cox proportional hazards models controlling for age, sex, socioeconomic status, ethnicity and other conditions. A total of 3898 young patients with incident IBD were matched to 15,571 controls. IBD patients were significantly more likely to develop PTSD [adjusted hazard ratio (aHR) 2.47, 95% CI 1.23–4.94], eating disorders (aHR 1.85, 95% CI 1.05–3.26), self-harm (aHR 1.49, 95% CI 1.00–2.21), sleep disturbance (aHR 1.40, 95% CI 1.15–1.71), depression (aHR 1.34, 95% CI 1.16–1.56) and anxiety disorder (aHR 1.25, 95% CI 1.06–1.48). These findings highlight the need to screen for these conditions in young patients.
