Road traffic injuries (RTIs) are a serious global problem, and a huge challenge for both economic development and public health.
This longitudinal study was based on the national data from Chinese authorities. Descriptive analysis was utilized to analyze the prevalence and trend of RTIs among different types, groups and regions. In addition, ridge regression or/and curve regression were also used to explore the relationship between those possible influencing factors and RTIs.
From 2010 to 2019, the death toll from motor vehicle accidents (MVAs) decreased firstly and then increased, while the death toll from non-MVAs continued to rise since 2012, and the death toll from pedestrian and occupant accidents fluctuated only a little. The mortality rate of MVA was relatively stable from 2010 to 2012, and declined from 2013. The mortality rate of motor vehicle accidents was higher in rural than urban, the same to male compared with female. The results of ridge regression showed that gross domestic product (GDP)-per-capita, total population, number of health personnel and car ownership were positively correlated with the death toll of non-MVAs ( < 0.05). Additionally, the results of curve regression suggested that the quadratic or cubic relationship between each factor and the number of MVAs was well fitted, while only partially fitted in fatalities.
In recent years, RTIs in China show different trends, and the problem of non-motor vehicle traffic injuries has been neglected which should be paid more attention. Moreover, according to the new trends and traffic conditions in RTIs revealed in this study, it is necessary to formulate targeted intervention measures establish a multi-faceted comprehensive safety system to reduce the disease burden of RTIs as well as the total injuries.
道路交通伤害（RTIs）是一个严重的全球性问题，对经济发展和公共卫生都是巨大的挑战。
本纵向研究基于中国官方的全国数据。描述性分析用于分析不同类型、群体和地区的 RTIs 的流行率和趋势。此外，还使用脊回归或/和曲线回归来探索这些可能的影响因素与 RTIs 之间的关系。
从 2010 年到 2019 年，机动车事故（MVAs）的死亡人数先降后升，而非 MVA 的死亡人数自 2012 年以来持续上升，行人和乘客事故的死亡人数仅略有波动。MVA 的死亡率在 2010 年至 2012 年相对稳定，从 2013 年开始下降。农村的 MVA 死亡率高于城市，男性与女性相比也是如此。脊回归的结果表明，人均国内生产总值（GDP）、总人口、卫生人员数量和汽车拥有量与非 MVA 的死亡人数呈正相关（<0.05）。此外，曲线回归的结果表明，各因素与 MVA 数量之间的二次或三次关系拟合较好，而与死亡率仅部分拟合。
近年来，中国的 RTIs 呈现出不同的趋势，非机动车交通伤害问题被忽视，应引起更多关注。此外，根据本研究揭示的 RTIs 新趋势和交通状况，有必要制定有针对性的干预措施，建立多方面的综合安全系统，以降低 RTIs 的疾病负担和总伤害。
