Analysis of epidemiology characteristics of road traffic injury and death in Tianjin

Objective To analyze the epidemiologic features of road traffic injury and death and provide scientific basis for prevention. Methods The data of road traffic injuries and deaths were collected from reports reported by medical organizations at all levels in the city, and were classified according to the International Classification of Diseases 10th (ICD-10). Results The total road traffic injury incidence rate was 339.61/100 000 and the mortality rate was 13.81/100 000. The average age of injury occurrence was (40.19±18.40), while that of death cases was (49.16±17.76). Among total injury occurrence cases, the number of male and female was 21 177 and 13 349. The sex ratio was 1.59:1. Among total death cases, the number of male and female was 1 077 and 327. The sex ratio was 3.29:1.The highest incidence rate was in those aged 30-years old, the highest mortality rate was 65 years and older. Farmers and workers were the top 1 and top 2 in both incidence rate and mortality rate. The highest four incidence rate areas were Doling District (704.06/100 000, Xiqing District (700.01/100 000), Binhai New District (672.55/100 000) and Jinnan District (539.23/100 000). Areas with the highest mortality rate were Jixian County (30.07/100 000), Jinghai County (28.01/100 000), Wuqing District (25.48/100 000) and Baodi District (23.19/100 000). Incidence peaked at the 2nd season and mortality at the 3rd and 4th season. Conclusions The average age of road traffic injuried cases is younger than death cases. Farmers and workers account for the highest proportion. Economically active areas have higher incidence rate, relatively undeveloped areas have higher mortality rate.
