Estimated prevalence and associated risk factors of attention deficit hyperactivity disorder (ADHD) among medical college students in a Chinese population

Attention deficit hyperactivity disorder (ADHD) is an early-onset neurodevelopmental disorder (Clauss-Ehlers, 2010; Sroubek et  al., 2013). It features the symptoms of attention deficit, excessive activity, or difficulty in controlling age-inappropriate behaviors (American Psychiatric Association, 2013). A formal diagnosis of ADHD meets these criteria: symptoms occur before twelve years of age, persist for more than six months, and cause functional impairments in at least two settings (such as school, home, or community) (American Psychiatric Association, 2013).
