QuickStats: Age-Adjusted Percentages* of Adults Aged ≥18 Years Who Have Epilepsy, by Epilepsy Status† and Race/Ethnicity§ — National Health Interview Survey, United States, 2010 and 2013 Combined¶

Weekly / June 17, 2016 / 65(23);611

The figure above is a bar chart showing that for the years 2010 and 2013 combined, 1.7% of adults aged ≥18 years (4.0 million) had epilepsy, 1.0% had active epilepsy, and 0.7% had inactive epilepsy. The prevalence of epilepsy and active epilepsy was significantly higher for non-Hispanic whites (1.9% and 1.1%, respectively) and non-Hispanic blacks (1.8% and 1.2%, respectively) compared with Hispanics (1.0% and 0.6%, respectively). The prevalence of inactive epilepsy was higher among non-Hispanic whites (0.8%) than Hispanics (0.4%). Non-Hispanic whites and non-Hispanic blacks did not differ significantly by epilepsy status.

* With 95% confidence intervals indicated with error bars.

† Respondents were asked, “Have you ever been told by a doctor or other health professional that you have a seizure disorder or epilepsy?” Persons responding “yes” were classified as having epilepsy. Those reporting having epilepsy who either were currently taking medication to control it, had one or more seizures in the past year, or both, were classified as having active epilepsy. Those with epilepsy who were neither taking medication for epilepsy nor had a seizure in the past year were classified as having inactive epilepsy.

§ Non-Hispanic white and non-Hispanic black categories were limited to adults categorized as of a single race. Hispanics might be of any race.

¶ Estimates are based on household interviews of a sample of the noninstitutionalized U.S. civilian population. Percentages were age-adjusted to the projected 2000 U.S. population as the standard population, by three age groups: 18–44, 45–64, and ≥65 years.
