Attention deficit hyperactivity disorder late birthdate effect common in both high and low prescribing international jurisdictions: systematic review

ConclusionsIt is the norm internationally for the youngest children in a classroom to be at increased risk of being medicated for ADHD, even in jurisdictions with relatively low prescribing rates. A lack of a strong effect in Denmark may be accounted for by the common practice of academic ‘redshirting’, where children judged by parents as immature have a delayed school start. Redshirting may prevent and/or disguise late birthdate effects and further research is warranted. The evidence of strong late birthdate effects in jurisdictions with comparatively low diagnosis/medication ra tes challenges the notion that low rates indicate sound diagnostic practices.
