Abstract:
Objective To analyze the epidemiological characteristic of stroke incidence and mortality in Chongqing, and to provide suggestions for targeted prevention and control of stroke. Methods Data of reported cases of ischemic stroke (I63), hemorrhagic stroke (I61-I62), subarachnoid hemorrhage (I60), and unclassified stroke (I64) in Chongqing in 2018 was collected. SPSS 25.0 was used to calculate the incidence, age-standardized incidence rate (ASIR), mortality, age-standardized mortality rate (ASMR) and proportion of stroke. The incidence and mortality of stroke were compared by Chi-square test between males and females, and between central urban areas and suburban counties. Results In 2018, the incidence and ASIR of stroke were 294.61/105 and 222.43/105 in Chongqing, respectively. The mortality and ASMR of stroke were 116.34/105 and 85.81/105. The incidence, ASIR and proportion of ischemic stroke were 186.63/105, 139.17/105 and 63.35%, respectively. The incidence of ischemic stroke in male was higher than that in female (χ2=18.52, P<0.001). The incidence of ischemic stroke in central urban areas was higher than that in suburban counties (χ2=29.50, P<0.001). The mortality of ischemic stroke in male was higher than that in female (χ2=6.67, P=0.010). The mortality of ischemic stroke in suburban counties was higher than that in central urban areas (χ2=17.55, P<0.001). The incidence, ASIR and proportion of hemorrhagic stroke were 78.15/105, 60.44/105 and 26.53%, respectively. The incidence of hemorrhagic stroke in male was higher than that in female (χ2=27.64, P<0.001). The incidence of hemorrhagic stroke in suburban counties was higher than that in central urban areas (χ2=18.60, P<0.001). The mortality of hemorrhagic stroke was the highest among all subtypes of strokes. The mortality, ASMR and proportion of hemorrhagic stroke was 64.44/105, 48.28/105 and 55.39%, respectively. The mortality of hemorrhage stroke in male was higher than that in female (χ2=23.46, P<0.001). The mortality of hemorrhage stroke in suburban counties was higher than that in central urban areas (χ2= 43.57, P<0.001). Conclusion The incidence and mortality of stroke in Chongqing were lower than the national average levels. The incidence of ischemic stroke was higher than that of hemorrhage stroke. The mortality of hemorrhage stroke was higher than that of ischemic stroke. Men and suburban counties were the focus of stroke prevention and control in Chongqing.
