Abstract:
Objective To understand the epidemiological characteristics and disease burden of road traffic injury death in a district of Shenzhen from 2013 to 2023.
Methods The incidence data of road traffic injury death were sourced from the Death Surveillance System of Chinese Center for Disease Control and Prevention. The indicators such as mortality rate, standardized mortality rate, average years of life lost (AYLL), potential years of life lost rate (PYLLR), and standardized potential years of life lost rate (SPYLLR) were used to describe the characteristics of road traffic injury death and related years of life lost. Software SPSS 25.0 and Joinpoint 5.1.0 were used for statistical analysis.
Results From January 1, 2013 to December 31, 2023, the average annual mortality rate of road traffic injury was 1.47/100,000, and the average annual standardized mortality rate was 4.32/100,000 in a district of Shenzhen, the rates were higher in men than in women (χ2=8.314, P<0.05). The mortality rate was highest in age group ≥ 65 years (11.56 per 100,000). No obvious change trend of standardized mortality rate of road traffic injury was observed over time (APC=3.72%, P=0.302). From 2013 to 2023, the road traffic injury deaths mainly occurred in pedestrians, motorcyclists and cyclists. Notably, the standardized mortality rates in cyclists and motorcyclists showed upward trends with time, the difference was significant (all P values <0.05), and there was no significant increase or decrease in the mortality rates in pedestrian. From 2013 to 2023, the AYLL caused by road traffic injury showed a downward trend (t=−3.57,1 P<0.05), and there was no significant change trend in PYLLR and SPYLLR (with t-values of −1.508 and −1.200, respectively, all P > 0.05), and the AYLL, PYLLR and SPYLLR were higher in men than in women (with t-values of 2.754, 4.867, and 5.747, respectively, all P < 0.05).
Conclusion From 2013 to 2023, the mortality rate of road traffic injury in a district of Shenzhen remained stable, and the mortality rate showed no obvious change over time. Road traffic injury is still one of the important causes of life lost in local area; It is necessary to carry out targeted health education about road safety in groups at high risk in addtion to strengthening comprehensive prevention and control of road trafic injury.
