The prevalence of ADHD is thought to be between 6-7% among children and adolescents and ~5% among adults (Willcutt, 2012).
Increasingly, evidence from multiple studies has pointed to comorbidity between ADHD and eating disorders (EDs). For example, one study found that young females with ADHD were 5.6 times more likely to develop clinical (i.e., diagnosable according to DSM-5) or subthreshold (i.e., sub-clinical) bulimia nervosa (BN) (Biederman et al., 2007). Another study found that found that 21% of female inpatients at an ED unit had six or more ADHD symptoms (Yates et al., 2009).
