A Retrospective Death Analysis Of Injury Among Inhabitants Of Zhangjiajie City From 2007 To 2009

Objective:This study aimed to understand the epidemiological characteristics and the disease burden of the deaths from injury in Zhangjiajie city, Hunan province. Therefore, we can identify which people could threat seriously by injury and provide scientific basis for injury prevention.Methods:The death data of Zhangjiajie residents from 2007 to 2009 were collected by the Zhangjiajie health bureau. In this research, mortality, proportion, cause eliminated life expectancy, potential years of life lost(PYLL),working potential years of life lost(WPYLL),valued potential years of life lost(VPYLL) were calculated.Results:1.The injury mortality of Hunan inhabitants was 51.70/100,000, and age-standardized mortality of that was 46.61/100,000. Mortality (67.91/100,000) and age-standardized mortality (63.03/100,000) for males from injury were higher than those for females (34.42/100,000 and 29.66/100,000). Mortality (20.10/100,000) and age-standardized mortality (18.58/100,000) of traffic accident was highest, Mortality (4.36/100,000) and age-standardized mortality (3.72/100,000) of poisoning was lowest. 2.Injures mortality of less than 20 years tended to decrease with the growth of age, while injures mortality of more than 20 years tended to increase with the growth of age; the injury mortality of Cili County was the highest, followed by Sangzhi County and the Wulingyuan area, the Yongding area was the lowest;3.The rate of age-standardized PYLL,age-standardized WPYLL,age-standardized VPYLL were 14.73/1000.9.81/1000,3.81/1000, respectively. The top three disease burdens due to injury were traffic accident, drowning, suicide, the rate of age-standardized PYLL age-standardized WPYLL of Cili County was the highest, followed by Yongding area and the Wulingyuan area, the Sangzhi County was the lowest; the rate of age-standardized VPYLL of Yongding area was the highest, followed by Sangzhi County and the Cili County, the Wulingyuan area was the lowest.4.Life expectancy of Zhangjiajie inhabitants was 80.954 years, while injury cause eliminated life expectancy was 82.596. Life expectancy increased 1.642 year, and the increasing magnitude was 2.028%.Conclusions:1. The mortality of injury among inhabitants in Zhangjiajie was higher than the national level; the male was higher than the femal; injures mortality of more than 20 years tended to increase with the growth of age; the injury mortality of Cili County was the highest, followed by Sangzhi County and the Wulingyuan area, the Yongding area was the . lowest; the top three causes of death due to injury among inhabitants in Zhangjiajie City were traffic accident, suicide, fall respectively.2. The top three disease burden-due to injury among inhabitants in Zhangj iajie City were traffic accident, drowning, suicide; the rate of age-standardized PYLL,age-standardized WPYLL of Cili County was the highest, followed by Yongding area and the Wulingyuan area, the Sangzhi County was the lowest; the rate of age-standardized VPYLL of Yongding area was the highest, followed by Sangzhi County and the Cili County, the Wulingyuan area was the lowest.
