To estimate the prevalence of stroke among community-dwelling individuals in the U.S. between 1999 and 2018 using a nationally representative sample.
There is a lack of recent data on trends in stroke prevalence among community dwelling individuals in the U.S. Prior epidemiological reports indicate decreasing stroke incidence and decreasing stroke mortality. Accurate and up-to-date representative estimates of stroke prevalence are needed to inform public health interventions.
We performed a series of cross-sectional analyses of data from 2,197 participants aged 20+ years in the 1999-2018 National Health and Nutrition Examination Surveys (NHANES) with self-reported history of stroke. We calculated age-standardized stroke prevalence over four-year epochs overall, and stratified by age group, sex, and race/ethnicity. Using the American Community Survey Public Use Microdata Sample from 2017-2018, we estimated the number of persons affected by stroke.

The overall age-standardized prevalence of stroke was 3.1% (95%CI: 2.9%-3.3%) from 1999-2002 to 2015-2018, which corresponds to 7.4 million (7.0-7.9 million) affected individuals. The age-standardized prevalence of stroke was stable from 1999-2002 to 2015-2018 (p-value-for-linear-trend-across-four-year-epochs=0.332). The age-standardized prevalence of stroke from 1999-2002 to 2015-2018 was higher among older individuals (aged ≥60 years: 7.7%, 7.2%-8.2%) compared to younger individuals (aged 20-39 years: 0.4%, 0.3%-0.5%; aged 40-59 years: 2.0%, 1.8%-2.3%), among non-Hispanic Black individuals (4.7%, 4.3%-5.1%) compared to other race/ethnicities (non-Hispanic White: 2.9%, 2.7%-3.2%; Mexican American: 2.6%, 2.3%-3.0%; Other: 3.5%, 2.8%-4.2%; Asian American: 1.7%, 1.3%-2.3%), and was similar by sex (men: 2.9%, 2.7%-3.2%; women: 3.2%, 3.0%-3.5%). The prevalence of stroke in each age, sex, and race/ethnicity group was stable from 1999-2002 to 2015-2018
The age-standardized prevalence of stroke in the non-institutionalized civilian adult population of the U.S. has not significantly changed between 1999 and 2018. In the context of other reports this likely reflects a combination of decreasing stroke incidence and improved stroke outcomes.
