"Our study findings suggest that there may be a large number of factors that affect ADHD diagnosis rates, including cultural factors that may influence the treatment-seeking behavior of some groups," said study lead author Darios Getahun, MD, PhD, from Kaiser Permanente Southern California's Department of Research & Evaluation. "These findings are particularly solid given that our study relied on clinical diagnoses of ADHD based on the criteria specified within the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders and that it represents a large and ethnically diverse population that can be generalized to other populations."In addition, the study found that boys were three times more likely to be diagnosed with ADHD than girls. Higher family incomes also were associated with the likelihood of ADHD diagnosis; children from families with a household income of more than $30,000 a year were nearly 20 percent more likely to be diagnosed with ADHD than children from families making less $30,000.
