Abstract:
Objective To describe and analyze the trend of stroke mortality in residents in death cause surveillance areas in Hebei province, and provide references for stroke prevention and control.
Methods This study collected the mortality data of stroke (ICD-10 code: I60–I64) from 2014 to 2020 in residents in death cause surveillance areas in Hebei province. Excel and SPSS 22.0 were used to calculate the mortality rate, standardized mortality rate, age-specific mortality rate and type specific mortality rate of stroke. The mortality rates between groups were compared with χ2 test, and percentage of annual change (APC) was used to analyze the trend of stroke mortality in the residents.
Results From 2014 to 2020, the average annual mortality rate of stroke in residents in death cause surveillance areas in Hebei was 122.82/100 000 (the standardized mortality rate: 107.78/100 000), the average annual mortality rate was 137.83/100 000 in men (the standardized mortality rate: 121.94/100 000) and 107.26/100 000 in women (the standardized mortality rate: 93.72/100 000). The mortality rate was higher in men than in women, the difference was significant (P<0.001). The mortality rate and standardized mortality rate of stroke all showed decreasing trends over time, and the differences were significant (APC=−1.00%, P=0.015; APC=−5.90%, P<0.001). From 2014 to 2020, the mortality of stroke in residents aged 45-64, 65-84 and ≥85 years all showed downward trends, and the differences were significant (APC=−3.90%, P=0.008; APC=−9.10%, P<0.001; APC=−4.10%, P=0.004). Hemorrhagic stroke was the main type causing death, and the mortality rate and standardized mortality rate of hemorrhagic stroke all showed downward trends with time, the differences were significant (APC=−1.90%, P=0.004; APC=−6.40%, P<0.001).
Conclusion The mortality rate of stroke in residents in death cause surveillance areas in Hebei showed a decreasing trend. It is necessary to strengthen the screening and surveillance in men and in the elderly aged over 65 years to reduce the mortality rate of stroke.
