【摘要】：目的研究南京市2013年脑卒中死亡的时空分布和变化特征。方法基于南京市2013年全年逐日脑卒中死亡个案数据,以区县为空间统计单元,利用GIS空间分析和统计分析工具,计算脑卒中死亡率和相对死亡率比值,进行空间分布特征和时间变化规律的分析。结果 2013年南京市脑卒中类疾病死亡占全年总死亡数的16.41%,脑卒中死亡率为75.53/10万。脑卒中死亡主要分布在65岁及以上人群(85.48%),女性的脑卒中死亡率略高于男性。南京市2013年脑卒中死亡具有明显的时空分布特征:冬春季节的脑卒中死亡发病率要明显高于夏秋季节,但盛夏的8月,死亡数也存在峰值;郊区县脑卒中死亡率及其季节差异均高于中心城区。结论应加强冬季、夏季以及郊区县脑卒中的死亡风险预警和科学防控。
[Abstract]:Objective to study the temporal and spatial distribution and variation characteristics of stroke death in Nanjing in 2013. Methods based on the daily stroke death data of Nanjing in 2013, taking the district and county as the spatial statistical unit, the ratio of stroke mortality and relative mortality was calculated by using GIS spatial analysis and statistical analysis tools, and the spatial distribution characteristics and temporal variation were analyzed. Results in 2013, the death rate of stroke diseases in Nanjing accounted for 16.41% of the total number of deaths in the whole year, and the mortality rate of stroke was 75.53 / 100000. The death rate of stroke was mainly among 65 years old and over (85.48%). The mortality rate of stroke in female was slightly higher than that in male. There are obvious temporal and spatial distribution characteristics of stroke death in Nanjing in 2013: the incidence of stroke death in winter and spring is significantly higher than that in summer and autumn, but the number of deaths also has a peak in August in midsummer, and the mortality rate and seasonal difference of stroke in suburban counties are higher than those in central urban areas. Conclusion early warning and scientific prevention and control of stroke death risk in winter, summer and suburban counties should be strengthened.
