Abstract:
ObjectiveTo analyze the incidence and trend of stroke in Beilun District, so as to provide evidence for identifying influencing factors and reducing stroke incidence. MethodsStroke cases from 2012 to 2023 were extracted from the Ningbo Chronic Disease Collaborative Management System. Population information of Beilun District during the same period was also collected. The annual incidence and trends of stroke were analyzed. ResultsFrom 2012 to 2023, the age-standardized incidence rate of stroke in Beilun District, Ningbo City was 317.68/100 000, showing an increasing trend with an average annual percentage change (AAPC) of 2.267% (P=0.034). Among all subdistricts in Beilun District, two showed a downward trend in incidence, while the rest showed an upward trend. The crude incidence rate of stroke was significantly higher in males than that in females (P<0.001). The age-standardized incidence rate in males was 406.08/100 000, showing an increasing trend (AAPC=3.956%, P<0.001). The incidence of stroke also showed an increasing trend in the following age groups: 30‒<45 years (AAPC=6.340%, P=0.004), 45‒<60 years (AAPC=4.997%, P<0.001), and 60‒<75 years (AAPC=3.282%, P=0.042). Across all years, males had higher crude incidence rates in both ischemic and hemorrhagic stroke than females (P<0.05). The age-standardized incidence rate of ischemic stroke showed a rising trend in both males and the general population (male AAPC=4.905%, P<0.001; overall population AAPC=3.065%, P=0.001). ConclusionThe age-standardized incidence of stroke in Beilun District is on the rise, with higher crude incidence rate in males than that in females. The onset age of stroke is gradually declining. The age-standardized incidence rate of male ischemic stroke shows a clear upward trend.
