Abstract
BACKGROUND: Stroke is a leading cause of death in Vietnam. However, a comprehensive analysis of stroke burden remains limited. This study aims to investigate the burden of stroke and various risk factors in Vietnam from 1990 to 2021. STUDY DESIGN AND METHODS: We utilized data from the Global Burden of Disease 2021 estimates. For the burden of stroke, we included the following variables as age-standardized rates (ASR) per 100,000 people per year: incidence, prevalence, disability-adjusted life years (DALYs), and mortality. Stroke-related mortality and DALYs associated with 23 risk factors were also analyzed. Trends were analyzed using joinpoint regression analysis. RESULTS: In 2021, stroke was responsible for 166,954 deaths (Males:96,764; Females:70,190). The ASR for stroke incidence was 203·36 (95%CI: 190·51-271·81) per 100,000 people, exceeding 187·98 in Southeast Asia and 141·55 globally. From 1990 to 2021, stroke incidence, death, and DALYs decreased steadily, with average annual percentage changes (AAPCs) of -0·34%, -0·49%, and -0·61%. The prevalence of stroke decreased among women (AAPC:-0·19%) and increased among men (AAPC:0·26%). Metabolic risks were the largest contributors to stroke-related mortality (144·89 per 100,000) and DALYs (2,872·37 per 100,000). The analysis revealed that behavioral risks were more prevalent in males, and metabolic risks in females. CONCLUSION: Stroke is the leading cause of death and disability in Vietnam. Although its overall burden has declined, the persistent and significant burden among males, coupled with specific risk factors, remains a major concern. Further researches are warranted to develop targeted interventions addressing the distinct risk factors.
