Abstract 86: Increasing World-Wide Stroke Burden, 2010-2017
Introduction: Although stroke-related mortality decreased over the last 3- decades, there is concern that morbidity and death rates may have increased over recent years. Methods: World-wide data available from the Institute for Health Metrics Evaluation’s Global Health Data Exchange (ghdx.healthdata.org/gbd) was analyzed to determine changes in stroke incidence, prevalence, death rates and associated disability adjusted life years (DALYs) between 2010-2017. Results: Over the 7-year period, global stroke incidence increased by 5.3% (148, 95% Uncertainty Interval, 140-157 to 156, 95% UI 146-168 per 100,000), prevalence by 19.3% (1,143, 95% UI 1,099-1,192 to 1,364, 95% UI 1,289-1,441 per 100,000), mortality by 5.3% (79, 95% UI 78-80 to 81, 95% UI 79-83 per 100,000) and DALYs by 2.7% (1,683, 95% UI 1,626-1,739 to 1,728, 95% UI 1,656-1,798 per 100,000). The Figure gives global trends for each metric between 1990-2017 (+/- 95% UI) and shows an increase in incidence and prevalence over the entire period with initial declines in mortality and DALYs that leveled off between about 2005-2013 and subsequently increased. Conclusion: The global burden of stroke is increasing. As other data suggest that most of the previous decline in stroke-related mortality was related to improvements in risk factor control, these data indicate that population level programs to reduce risk may need to be reinforced.
