Abstract: Objective To study the long-term trend of injury related deaths,the distribution of causes of injuries as well as the impact of injury related deaths on life expectancy in Jiading district,Shanghai,from 1985-2011.Methods Data were collected from vital statistics and registration system of Shanghai.Mortality level,main causes of death during the period were described.Time trend of death was analyzed and annual percentage changes(APCs)were estimated.Data related to cause eliminated life expectancy(CELE)and years of potential life lost(YPLL)were also calculated.Results The average crude death rates of injury during the period was 56.28/100 000 and injuries accounted for 7.81% of all deaths,ranking the fourth among the main causes of death for local population in Jiading.Injury was the first cause of death for the residents aged 1-39 years.Traffic accident,fall,suicide,drowning,and suffocation were the five top causes of injury.The death rate of traffic accident rose from 1993 and decreased from 2005 while fall showed a rising trend from 1994 with an APC of 6.35%.During the 27 years,the average years of life expectancy lost due to injury in the males and females was 1.28 and 1.13,respectively,and the average YPLL due to injury was 1 208.16 person years per 100 000.The average proportion of YPLL due to injury on total deaths was 20.13%,while YPLL due to injury decreased annually.ConclusionThe trends of mortality rates for injuries were declining,while the diseases of circulatory system and neoplasms were still the primary causes of death among the population of Jiading district.Injury is still the main death cause for young people,and the highest priority of injury prevention should be given to fall and traffic accident.
