Prevalence of Stroke — Behavioral Risk Factor Surveillance System, United States, 2011–2022

Stroke was the fifth leading cause of death in the United States in 2021, and cost U. S. residents approximately 56. 2 billion during 2019-2020. During 2006-2010, selfreported stroke prevalence among noninstitutionalized adults had a relative decrease of 3. 7%. Data from the Behavioral Risk Factor Surveillance System were used to analyze agestandardized stroke prevalence during 2011-2022 among adults aged ≥18 years. From 2011-2013 to 2020-2022, overall self-reported stroke prevalence increased by 7. 8% nationwide. Increases occurred among adults aged 18-64 years; females and males; non-Hispanic Black or African American (Black), non-Hispanic White (White), and Hispanic or Latino (Hispanic) persons; and adults with less than a college degree. Stroke prevalence was higher among adults aged ≥65 years than among younger adults; among non-Hispanic American Indian or Alaska Native, non-Hispanic Native Hawaiian or Pacific Islander, and Black adults than among White adults; and among adults with less than a high school education than among those with higher levels of education. Stroke prevalence decreased in the District of Columbia and increased in 10 states. Initiatives to promote knowledge of the signs and symptoms of stroke, and the identification of disparities in stroke prevalence, might help to focus clinical and programmatic interventions, such as the Million Hearts 2027 initiative or the Paul Coverdell National Acute Stroke Program, to improve prevention and treatment of stroke. * https: //www. cdc. gov/nchs/products/databriefs/db456. htm56. 2 billion during 2019-2020 (1). A report on stroke prevalence using Behavioral Risk Factor Surveillance System (BRFSS) data indicated that overall self-reported stroke prevalence among noninstitutionalized adults aged ≥18 years in all 50 states and the District of Columbia (DC) had a relative decrease of 3. 7% during 2006-2010 (2). The current report used BRFSS data to assess stroke prevalence trends during 2011-2022 by sociodemographic characteristics and place of residence. Methods Data Source and Study ParticipantsBRFSS is a state-based surveillance system of noninstitutionalized U. S. civilian adults aged ≥18 years, administered in U. S. states and territories in coordination with CDC. Each year, health departments conduct a cross-sectional, randomdigit-dialed landline and cellular telephone survey assessing Morbidity and Mortality Weekly Report
