Why the study?
Stroke burden in China has increased over the past 40 years, prompting an evaluation of recent trends in stroke prevalence from 2013 to 2019 stratified by sociodemographic characteristics.
The prevalence of stroke in China has continued to increase from 2013 to 2019, highlighting the need for targeted public health interventions.
Rising stroke prevalence in China merits surveillance; cross-sectional data leave open determinants and prevention effects.
Background: The stroke burden in China has increased during the past 40 years. The present study aimed to determine the recent trends in the prevalence of stroke from 2013 to 2019 stratified by sociodemographic characteristics, including sex, age, residence, ethnicity, and province within a population-based screening project in China. Methods: We made use of data generated from 2013 to 2019 in the China Stroke High-risk Population Screening Program. All living subjects with confirmed stroke at interview were considered to have prevalent stroke. All analyses of prevalence of stroke were weighted and results were presented as percentage and 95% confidence interval (CI). Findings: for trend <0.001). The weighted prevalence of stroke was higher for male sex, older age, and residence in rural and northeast areas. Interpretation: The prevalence of stroke in China and most provinces has continued to increase in the past 7 years (2013-2019). These findings, especially in provinces with high stroke prevalence, can help public health officials to increase province capacity for stroke and related risk factors prevention. Fundings: This study was supported by grants from the National Major Public Health Service Projects.
