2018年深圳市居民伤害死亡率与公共安全指数的相关性分析

Correlation Analysis between Injury Mortality and Public Safety Index in Shenzhen,2018

目的分析2018年深圳市居民的伤害死亡基本情况及其与公共安全指数的相关性,为制定伤害预防策略提供理论依据。方法数据来源于深圳市疾病预防控制中心的死因监测系统。根据深圳市公安局发布的公共安全指数,采用Pearson相关分析探索伤害死亡率与公共安全指数的相关性。结果2018年深圳市居民的伤害死亡例数为1529,年伤害死亡率为13.16/10万,前三位伤害死因分别为自杀(41.92%)、道路交通伤害(19.82%)和非故意跌落(14.06%)。公共安全指数排名前三位的区分别是盐田区(94.36±0.61)、大鹏新区(93.98±1.17)和坪山区(92.67±1.44)。Pearson相关分析结果显示,深圳市道路交通伤害死亡率与交通安全指数呈显著的负相关关系(r=-0.510,P<0.05)。结论深圳市居民的主要伤害死因包括自杀、道路交通伤害及非故意跌落,且道路交通伤害死亡率与公共安全指数呈显著的负相关关系,可作为道路交通伤害死亡率的评估指标。

Objective To analyze the basic situation of injury-induced deaths of Shenzhen residents in 2018 and its correlation with public safety index,so as to provide theoretical basis for the development of injury prevention strategies.Methods Data were obtained from the cause of death monitoring system of Chinese Center for Disease Control and Prevention and the public safety index released by Shenzhen Municipal Public Security Bureau.Pearson correlation analysis was used to explore the correlation between the injury mortality and the public safety index.Results In 2018,the number of injury deaths in Shenzhen was 1,529,and the annual death rate was 13.16/100,000.The top three causes of injury deaths were suicide(41.92%),road traffic injuries(19.82%)and accidental fall(14.06%).The top three spots in the public safety indexes are Yantian District(94.36±0.61),Dapeng District(93.98±1.17)and Pingshan District(92.67±1.44).Pearson correlation analysis showed that there was a significant negative correlation between the mortality of road traffic injury and the traffic safety index in Shenzhen(r=-0.510,P<0.05).Conclusions The primary injury deaths were suicide,road traffic injury and accidental fall,and the mortality of traffic accident is negatively correlated with the public safety index,which can be considered as the evaluation index for the occurrence of road traffic injury mortality.
