The prevalence of stroke in the United States has increased from 2011-2013 to 2020-2022, according to a recent report published in the May 23 issue of the U.S. Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report.

Dr. Omoye E. Imoisili and colleagues from the CDC in Atlanta analyzed age-standardized stroke prevalence data from the Behavioral Risk Factor Surveillance System, covering the years 2011 to 2022. Their findings revealed a 7.8 percent increase in overall self-reported stroke prevalence nationwide during this period.

The increase in stroke prevalence was observed across various demographic groups. Adults aged 18 to 64 years, both women and men, non-Hispanic Black or African American individuals, non-Hispanic Whites, Hispanic or Latino persons, and adults with less than a college degree all experienced rises in stroke prevalence.

The data also indicated that stroke prevalence was higher among adults aged 65 years and older compared to younger adults. Additionally, non-Hispanic American Indian or Alaska Native, non-Hispanic Native Hawaiian or Pacific Islander, and Black adults had higher prevalence rates compared to White adults. Adults with less than a high school education had a higher stroke prevalence compared to those with higher education levels.

Geographically, the prevalence of stroke increased in ten states while it decreased in the District of Columbia.

The authors emphasized the importance of advancing focused, evidence-based practices and programs aimed at stroke awareness, prevention, and treatment to improve the nation's cerebrovascular health. This rise in stroke prevalence underscores the need for ongoing public health efforts to address this critical issue.
