Research on disease burden caused by traffic injury in Hubei, 1990-2015

Objective To understand the disease burden caused by injury in the population of Hubei province from 1990 to 2015 and provide scientific evidence for the prevention and control of traffic injury. Methods Based on the results of the Global Burden of Disease Study 2015 (GBD 2015), the mortality, years of life lost due to premature mortality (YLLs), years lived with disability (YLDs) and disability-adjusted life years (DALYs) in Hubei of China were used to analyze the change of disease burden caused by injury in Hubei from 1990 to 2015. Results The mortality rate of traffic injury was 25.6/100 000 in Hubei in 2015 (37.7/100 000 in males and 12.7/100 000 in females). The standardized mortality rate decreased from 25.3/100 000 in 1990 to 22.1/100 000 in 2015, a decline of 12.6%. The standardized mortality rate decreased in both males and females. The DALYs, YLDs and YLLs by traffic injury were 651, 87 and 564 thousands person years respectively. The overall standardized DALY rate decreased from 1 271.7/100 000 in 1990 to 1 064.0/100 000 in 2015, a decline of 16.3%. The decrease rate was 8.3% in males and 32.9% in females. In different type traffic injuries in 2015, the DALYs caused by pedestrian walkway injury was highest, accounting for 53.4%. In Hubei, the DALYs caused by traffic injury were mainly distributed in age group 15-69 years. Conclusions Compared with 1990, the standardized mortality rate and DALY rate decreased in Hubei in 2015, but the death toll and DALYs were still high, especially those caused by pedestrian walkway injury. The disease burden caused by traffic injury were more serious in males than in females.
