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

Area of Science:

• Public Health
• Epidemiology
• Cardiovascular Disease Research

Background:

• Stroke is a leading cause of death and significant economic burden in the U.S.
• Previous data (2006-2010) indicated a slight decrease in self-reported stroke prevalence.
• Understanding current trends is crucial for public health strategies.

Purpose of the Study:

• To analyze trends in age-standardized, self-reported stroke prevalence among U.S. adults from 2011 to 2022.
• To identify demographic and geographic disparities in stroke prevalence.
• To inform public health initiatives for stroke prevention and treatment.

Main Methods:

• Utilized data from the Behavioral Risk Factor Surveillance System (BRFSS).
• Analyzed age-standardized stroke prevalence among adults aged 18 years and older.
• Compared prevalence data between 2011-2013 and 2020-2022.

Main Results:

• Overall self-reported stroke prevalence increased by 7.8% nationwide between 2011-2013 and 2020-2022.
• Increases were noted in younger adults (18-64), both sexes, multiple racial/ethnic groups (Black, White, Hispanic), and those with lower educational attainment.
• Higher prevalence was observed in older adults (≥65), certain racial/ethnic groups (AI/AN, NHOPI, Black), and individuals with less than a high school education.

Conclusions:

• Stroke prevalence has increased nationally, with significant disparities observed across age, sex, race/ethnicity, and education levels.
• Targeted public health initiatives are needed to address these disparities and improve stroke prevention and treatment.
• Programs like Million Hearts 2027 and the Paul Coverdell National Acute Stroke Program are vital for intervention.
