The Center for Disease Control (CDC) says Southern states have the highest rate of Attention-Deficit/Hyperactivity Disorder (ADHD).
In 2007, 4.1 million US children aged 4- to 17-years-old were diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD), and of those, more than half were taking drugs to treat the disorder.
According to the study, the highest rates were documented in five Southern states, including North Carolina, Louisiana, West Virginia, Arkansas, and Delaware. The percentage of children with current ADHD diagnosis and taking ADHD medication was lowest in Nevada, Alaska, and California, while the highest was reported in Iowa, Missouri, and Mississippi.
The study's authors reported that differences in state-based ADHD medication treatment supports reports by the US Food and Drug Administration of uneven product distribution of common ADHD medications, contributing to ADHD medication shortages in certain states. Researchers hope that the results of this study may serve to inform state-based policy and programmatic efforts.
The lowest state-based rates of medicated ADHD were documented in Nevada, California, Alaska, Hawaii, and New Mexico.
