Trends in incidence of stroke among residents in Jinhua Cityfrom 2015 to 2020 / 预防医学

ABSTRACT

Objective@#To analyze the incidence and trends for incidence of stroke in Jinhua City from 2015 to 2020, so as to provide insights into stroke control.@*Methods@#The data pertaining to incidence of stroke among registered residents in Jinhua City from 2015 to 2020 were collected from Zhejiang Provincial Information Management System for Surveillance on Chronic Diseases. The incidence of stroke was estimated and standardized to the Sixth National Population Census in 2010. The trend in incidence of stroke was evaluated using annual percent change (APC).@*Results@#Totally 120 993 stroke cases were reported in Jinhua City from 2015 to 2020, and the annual mean crude incidence and standardized incidence of stroke were 415.68/105 and 339.67/105, respectively. There were no significant trends in crude incidence (APC=0.30%, t=0.234, P=0.827) and standardized incidence of stroke (APC=-0.99%, t=0.946, P=0.398). The crude incidence of stroke was significantly higher in men than in women (457.38/105 vs. 372.62/105; χ2 =1 262.329, P<0.001), and the crude incidence of stroke appeared a tendency towards a rise with age (χ2 trend=377 708.263, P<0.001), with a tendency towards a decline among residents at ages of 75 years and older (APC=-2.66%, t=3.078, P=0.037). There were 94 038 residents with ischemic stroke (77.72%) and 24 176 residents with hemorrhagic stroke (19.98%), and both the crude incidence (APC=1.78%, t=3.440, P=0.026) and standardized incidence of hemorrhagic stroke (APC=2.66%, t=3.911, P=0.017) appeared a tendency towards a decline.@* Conclusions@#The incidence of stroke remained relatively stable in Jinhua City from 2015 to 2020; however, the overall incidence was still high. Ischemic stroke was the predominant type of stroke, and men and middle-aged and elderly people are at high risk of stroke.
