Objective:
To analyze the status and trend of injury burden in 1990 and 2010 for Chinese people.
Methods:
We used results of the Global Burden of Diseases Study 2010 (GBD 2010) to analyze the status of injury burden in China. The main outcome measurements included years of life lost (YLL), years lived with disability (YLD), and disability-adjusted life years (DALY). Moreover, the China Census in 2010 was used as the reference population to calculate the age-standardized rate with each five-year as an age group. We also calculate the percentage change from 1990 to 2010 and analyze the trend of injury burden in China for the past twenty years.
Results:
In 2010, a total of 796 240 people died of injury. The crude death rate of injury in China was 59.34/100 000 and the standardized death rate was 61.87/100 000; the YLL due to injury was 31.7593 million person years. The YLD due to injury was 9.0447 million person years and the DALY due to injury was 40.8040 million person years. In 2010, the top five causes of death related to injury were road traffic, injury, suicide, falls, drowning and poisoning. The death number for the five causes were 282 576, 172 964, 115 294, 67 402, and 36 997, respectively. The top five causes of DALY related to injury were road traffic injury, falls, suicide, drowning and poisoning and the DALY were 14.9623 million, 7.0583 million, 5.9699 million, 3.6634 million, and 1.6137 million person years. From 1990 to 2010, the burden attributable to road traffic injury increased quickly, the standardized death rate increased from 15.76/100 000 to 21.83/100 000, up 38.54%; the standardized DALY rate increased from 930.12/100 000 to 1142.19/100 000, up 22.80%. From 1990 to 2010, the burden attributable to suicide decreased, the standardized death rate decreased from 22.62/100 000 to 13.62/100 000, down 39.82%, and the standardized DALY rate decreased from 875.09/100 000 to 462.28/100 000, down 47.17%. The disease burden of injury topped at the group aged 20-24, followed by group aged 40-44 and group aged 35-39, the DALY for the three age groups were 4.2211 million,4.1655 million, and 4.0319 million person years, respectively.
Conclusion:
Injury was the main disease for burden among Chinese population, especially among young adults. In recent years, the burden attributable to road traffic injury increased quickly. Targeted prevention and control measures for road traffic injury, falling, suicide and other key injury should be in place to reduce the burden of injury effectively.
