Trends in incidence of stroke in Lianyungang City from 2014 to 2020 / 预防医学

ABSTRACT

Objective@# To investigate the incidence and trends in incidence of stroke among residents in Lianyungang City, Jiangsu Province from 2014 to 2020, so as to provide insights into stroke control. @*Methods@#The stroke morbidity data in Lianyungang City from 2014 to 2020 were captured from Lianyungang Municipal System for Monitoring of Cardiovascular and Cerebrovascular Diseases, and standardized by the sixth national population census data in China in 2010. The trends in stroke incidence were evaluated using average annual percentage change (AAPC), and the gender-, age-, region- and disease type-specific incidence and trends in incidence of stroke were descriptively analyzed. @*Results@#Totally 162 423 new stroke cases were diagnosed in Lianyungang City from 2014 to 2020 new case, and the annual mean crude and standardized incidence rates were 435.32/105 and 357.28/105, which both appeared a tendency towards a rise (AAPC=12.61%, t=39.098, P<0.001; AAPC=9.91%, t=6.123, P<0.001) . The standardized incidence of stroke was significantly higher in men than in women (389.63/105 vs. 327.17/105; χ2=4.056, P=0.044). The crude incidence of stroke appeared a tendency towards a rise with age among residents (χ2trend=258.219, P<0.001), and appeared a tendency towards a rise among residents at ages of <35 (AAPC=22.52%, t=6.723, P<0.001), 35 to 64 (AAPC=9.78%, t=7.867, P<0.001) and 65 years and older (AAPC=10.24%, t=5.156, P<0.001). The crude incidence was higher in rural areas than in urban areas (437.72/105 vs. 425.31/105; χ2=20.709, P<0.001). Ischemic stroke was the predominant type (139 680 cases, 86.00% of all cases), and both the crude and standardized incidence appeared a tendency towards a rise (AAPC=13.79%, t=16.865, P<0.001; AAPC=10.88%, t=5.128, P<0.001). @*Conclusion@# The incidence of stroke appeared a tendency towards a rise among residents living in Lianyungang City from 2014 to 2020. Men, middle-age and elderly residents and rural residents are high-risk populations for stroke control.
