ABSTRACT
Objective To analyze the characteristics and changing trend of injury death among elderly residents aged 65 and above in Chongqing from 2013 to 2017, and to provide a basis for formulating intervention strategies for elderly injuries. Methods Based on monitoring data of death causes of permanent residents in Chongqing from 2013 to 2017, the injury death cases of elderly residents aged 65 and above were extracted, and the mortality rate and sequence were calculated. The standard mortality rate was calculated based on the standard population composition of the sixth national population census in 2010. The Joinpoint Regression Program 4.2 software was used to analyze the death trend. Results From 2013 to 2017, the average annual crude injury mortality rate of Chongqing residents aged 65 and above was 140.89/100 000, and the standardized mortality rate was 12.57/100 000. The crude death rate of male elderly residents was higher than that of female residents in the same year (P <0.001), and the injury mortality rate increased with the age of the elderly (P <0.001). The injury mortality rate of female and all elderly residents, and elderly residents in the 75- and 85-year-old groups showed an upward trend (P<0.05). Falls, road traffic injuries, suicide, other accidental injuries and drowning were the top five causes of injury death in Chongqing, accounting for 93.16% of the total injury deaths. In the past five years, the fall mortality of elderly residents in Chongqing showed an upward trend (P < 0.05). Falling was the first cause of injury death for elderly aged 70 and above in Chongqing. The crude rate of death of elderly residents aged 85 and over was 313.52 /100 000. Conclusion The injury mortality and fall mortality of elderly residents aged 65 and above in Chongqing showed a rising trend in the past five years. It is urgent to take measures to prevent injury and falls for seniors in Chongqing.
