Researchers looked at data involving 1,354 youths with attention-deficit/hyperactivity disorder in the UK and correlated every decile increase in the Index of Multiple Deprivation with a 10% reduced likelihood of ADHD treatment receipt, indicating a significantly higher likelihood of ADHD drug prescriptions among those who live in poor areas. "The social gradient in [children and young people's] receipt of medication represents a novel risk factor that clinicians should aim to modify," researchers wrote in the journal BJPsych Open.
