Characteristics and changing trend of deaths caused by road traffic injury among children and adolescents in Chongqing Municipality, 2012-2021

Objective To analyze the characteristics and changing trend of deaths caused by road traffic injury among children and adolescents in Chongqing Municipality from 2012 and 2021, and to provide suggestions for conducting road traffic injury intervention. Methods The information regarding death cases due to road traffic injury (ICD-10:V01-V99) in children and adolescents in Chongqing Municipality from 2012 to 2021 were derived from Chongqing death registration system. The mortality rate and proportion of road traffic accident were analyzed by SPSS 25.0 software. The differences in the mortality rates of road trafficinjury between males and females as well as between urban and rural areas were compared by χ² test. The trend changes in the mortality rates of road traffic injury between 2012 and 2021 were analyzed by annual percent change (APC). Results The mortality rate of road traffic injury among children and adolescents in Chongqing Municipality decreased from 6.80/100,000 in 2012 to 1.83/100,000 in 2021, the APC was -14.62%, and the changing trend showed a statistically significant difference (t=15.088, P<0.001). The mortality rates of road traffic injury before 2016 were higher in males than in females, and those before 2014 were higher in rural area than in urban area, showing statistically significant differences (both P<0.05). The mortality rates of road traffic injury in male, female, urban and rural children and adolescents decreased by 14.96%, 14.02%, 10.60% and 15.21% annually, respectively, and the changing trends showed statistically significant differences (all P<0.05). The mortality rates of road traffic injury in children and adolescents aged 0-4 years, 5-9 years, 10-14 years, and 15-17 years decreased by 13.84%, 16.22%, 11.93% and 15.55% annually, respectively, and the changing trends showed statistically significant differences (all P<0.05). Pedestrian injuries due to transport accidents accounted for more than 70% of road traffic injury. Conclusion The mortality rates of road traffic injury among children and adolescents in Chongqing Municipality from 2012 and 2021 showed a rapid downward trend. Road traffic injury involving children and adolescents as pedestrians was the main cause. It should be conducted comprehensive intervention on road traffic injury persistently.
