Abstract

Background Although stroke is the second leading cause of death worldwide, no comprehensive and comparable assessment of incidence, prevalence, mortality, disability, and epidemiological trends has been estimated for most regions. We used data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2010 (GBD 2010) to estimate the global and regional burden of stroke during 1990.2010. Methods We searched Medline, Embase, LILACS, Scopus, PubMed, Science Direct, Global Health Database, the WHO library, and WHO regional databases from 1990 to 2012 to identify relevant studies published between 1990 and 2010. We applied the GBD 2010 analytical technique (DisMod-MR), based on disease-specifi c, pre-specifi ed associations between incidence, prevalence, and mortality, to calculate regional and country-specifi c estimates of stroke incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) lost by age group (<75 years, .75 years, and in total) and country income level (high-income, and low-income and middle-income) for 1990, 2005, and 2010. Findings We included 119 studies (58 from high-income countries and 61 from low-income and middle-income countries). From 1990 to 2010, the age-standardised incidence of stroke signifi cantly decreased by 12% (95% CI 6.17) in high-income countries, and increased by 12% (.3 to 22) in low-income and middle-income countries, albeit nonsignifi cantly. Mortality rates decreased signifi cantly in both high income (37%, 31.41) and low-income and middleincome countries (20%, 15.30). In 2010, the absolute numbers of people with fi rst stroke (16-9 million), stroke survivors (33 million), stroke-related deaths (5-9 million), and DALYs lost (102 million) were high and had signifi cantly increased since 1990 (68%, 84%, 26%, and 12% increase, respectively), with most of the burden (68-6% incident strokes, 52-2% prevalent strokes, 70-9% stroke deaths, and 77-7% DALYs lost) in low-income and middle-income countries. In 2010, 5-2 million (31%) strokes were in children (aged <20 years old) and young and middle-aged adults (20.64 years), to which children and young and middle-aged adults from low-income and middle-income countries contributed almost 74 000 (89%) and 4-0 million (78%), respectively, of the burden. Additionally, we noted signifi cant geographical diff erences of between three and ten times in stroke burden between GBD regions and countries. More than 62% of new strokes, 69-8% of prevalent strokes, 45-5% of deaths from stroke, and 71-7% of DALYs lost because of stroke were in people younger than 75 years. Interpretation Although age-standardised rates of stroke mortality have decreased worldwide in the past two decades, the absolute number of people who have a stroke every year, stroke survivors, related deaths, and the overall global burden of stroke (DALYs lost) are great and increasing. Further study is needed to improve understanding of stroke determinants and burden worldwide, and to establish causes of disparities and changes in trends in stroke burden between countries of diff erent income levels.
