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。
Objective To study the spatial and temporal distribution and change characteristics of stroke death in Nanjing in 2013. Methods Based on the data of daily stroke deaths in 2013 in Nanjing City, the spatial and temporal distributions of stroke and mortality were calculated using the spatial statistical units of districts and counties and GIS spatial analysis and statistical analysis tools. Regular analysis. Results In 2013, stroke deaths in Nanjing accounted for 16.41% of the total number of deaths in the year and stroke death rate was 75.53 / 100,000. Stroke deaths were mainly found in people 65 and over (85.48%), and stroke death rates in women were slightly higher than those in men. In 2013, the death rate of stroke in Nanjing city was significantly higher than that in summer and autumn. However, the death rate of stroke in winter and spring was significantly higher than that in summer and autumn. Seasonal differences are higher than the central city. Conclusion Early warning and scientific prevention and control of stroke risk in winter, summer and suburban counties should be strengthened.
