HealthDay News — From 2007 to 2016, the prevalence of attention-deficit/hyperactivity disorder (ADHD) increased among adults and children, according to a study published online Nov. 1 in JAMA Network Open.

Winston Chung, MD, from Kaiser Permanente Northern California in San Francisco, and colleagues examined trends in the diagnosis of ADHD in 5,282,877 adult patients and 867,453 children aged 5 to 11 years who received care from Jan. 1, 2007, to Dec. 31, 2016.

The researchers found that 1.12% of the adults received a diagnosis of ADHD. From 2007 to 2016, there was an increase in prevalence from 0.43 to 0.96%. Prevalence increased from 2.96 to 3.74% among children. Annual adult ADHD prevalence increased for every race/ethnicity during the study period; the highest prevalence rates were consistently seen for white individuals. From 2007 to 2016, there was an increase in the incidence of ADHD diagnosis, from 9.43 to 13.49 per 10,000 person-years. The odds of receiving an ADHD diagnosis were increased with having an eating disorder, depressive disorder, bipolar disorder, or anxiety disorder (odds ratios, 5.192, 4.118, 4.722, and 2.438, respectively).
