The Burden of Stroke in The Municipality of Chongqing, China, From 1990 To 2016
Abstract Background: The burden of stroke varies substantially across regions in China. However, comprehensive comparisons between regions are lacking. This study aims to analyze variations in stroke burden in the municipality of Chongqing, Western China, from 1990-2016. Methods: Data on prevalence, years lived with disability (YLDs), mortality, years of life lost (YLLs), and disability-adjusted life years (DALYs) by age, sex, location, and year were extracted from the 2016 Global Burden of Disease Study (GBD 2016) of China between 1990-2016. The datasets were compared to examine the temporal trends in stroke burden in the last two decades.Results: In 2016, there were 670,438 cases of stroke, 41,022 deaths, and 847,437 DALYs due to stroke in Chongqing. Age-standardized mortality and DALY rates of IS and HS were higher in men whereas age-standardized prevalence rates of IS were higher in women. From 1990 to 2016, age-standardized prevalence rates of overall stroke increased by 33.29%, whereas mortality rates and DALYs decreased by 34.51% and 34.79%, respectively. YLLs were the main contributor to DALYs; however, the YLL/YLD ratio decreased over time. During the study period, the overall burden of stroke decreased, whereas the prevalence rate of IS increased in all age groups.Conclusions: Despite a decrease in mortality rates, the increase in the prevalence of stroke in Chongqing stresses the need to allocate more health resources. Special attention should be paid to discrepancies in the estimation of the type of stroke according to gender and age to determine mechanisms that explain the causes of stroke.
