Abstract

Key Points Question What is the association between relative age in the school year and incidence of intellectual disability, attention-deficit/hyperactivity disorder, and depression? Findings In this cohort study of 1 042 106 children in the UK Clinical Practice Research Datalink, relatively young children were 1.3 times more likely than the oldest quarter of children in the school year to be diagnosed with intellectual disability, 1.4 times more likely to be diagnosed with ADHD, and 1.3 times more likely to be diagnosed with depression. Meaning Effective interventions may be needed to minimize the negative intellectual ability and mental and physical health consequences of relative youth.
