Summary
This study analyzes the temporal trends in the disease burden and risk factors of transport injuries (TI) among children aged 0–14 years in China from 1990 to 2019. Motivated by the persistent public health challenge of traffic accidents and the specific vulnerability of children, the research aims to identify pediatric TI preventive priorities by examining epidemiological patterns stratified by age, sex, and road-user type. The authors conducted a secondary data analysis using estimates from the Global Burden of Disease (GBD) 2019 dataset, retrieved via the Global Health Data Exchange query tool. They estimated incidence rates, death rates, and disability-adjusted life years (DALYs) with 95% uncertainty intervals. To evaluate temporal trends, the study employed Joinpoint regression analysis to calculate annual percentage changes (APC) and average annual percent changes (AAPC), allowing for the identification of distinct trend intervals and inflection points. Stratified analyses were performed to assess disparities across age groups (0–4, 5–9, 10–14 years), gender, and road-user categories. The results revealed a divergent trend: while the overall incidence rate of TI increased annually by 1.18% (rising from 322 to 463 per 100,000), both mortality and DALY rates decreased significantly, with average annual declines of 3.87% and 3.83%, respectively. Boys experienced higher incidence rates than girls but showed faster declines in mortality and DALYs. Children aged 0–4 years consistently exhibited the highest mortality and DALY rates, although their incidence trend differed from older groups. Cyclist road injuries were the primary cause of TI incidence, whereas pedestrian injuries accounted for the highest mortality and DALY burden. Alcohol use was identified as the most significant risk factor for TI-related death and disability, while low temperature appeared to be a protective factor, associated with negative rates of mortality and DALYs. The study concludes that despite improvements in traffic safety legislation and infrastructure, which have reduced mortality, the rising incidence of TI necessitates targeted interventions. The authors emphasize the need to prioritize awareness and preventive measures for boys, children under five, and vulnerable road users like pedestrians and cyclists. They advocate for enhanced enforcement of drink-driving laws and improved road safety education and engineering to mitigate the ongoing burden of transport injuries in China’s pediatric population.
