The Centers of Disease Control (CDC) and Prevention’s National Center’s official report on the rates of attention-deficit/hyperactivity disorder (ADHD) in US children shows the trend is upward. Nonetheless, there were different prevalence rates amongst different ethic groups.
Mexican children show consistently lower ADHD prevalence rates than any other ethnic or racial group.
From 1998–2000 through 2007–2009, the prevalence of ADHD increased among children aged 5–17 years, from 6.9% to 9.0%. These increases were seen among both boys and girls, among children in most racial and ethnic groups except Mexican children, and among children with family income less than 200% of the poverty level. By geographic region, ADHD was more prevalent in the South and Midwest regions of the United States than in the Northeast and West regions during 2007–2009.
ADHD is one of the most common mental health disorders of childhood. The symptoms of ADHD (inattention, impulsive behavior, and hyperactivity) begin in childhood and often persist into adulthood. These symptoms frequently lead to functional impairment in academic, family, and social settings.
