Stream 1 primary objective is to compare the prevalence and cumulative incidence of mental health conditions in children, adolescents and young adults (aged 5-25 years) with a diagnosis of Inflammatory Bowel Disease (IBD), compared to matched population controls without a diagnosis of IBD. The secondary objective is to determine the severity of mental health outcomes in those with and without a diagnosis of IBD.
