Abstract: ObjectiveTo study the accidental death level, cause,distributional,characteristic and tendency,and provide scientific basis for prevention and controlment.MethodsSiglificance test of linear regression in 2*C table and epidemiology method were used to study the trend of the mortality and YPLL rate.ResultsThe mortality rate of accidental injury in ten years was 84.81/105,lower than respiratory disease,cancerand circulation system disease,ranked the fourth among all death causes.While the YPLL of accidental injury was the first rank.The mortality rate of accidental inju y death rate was on the decrease(P<0.01).The SMR(84.96/105)was higher than the whole country (65.24/105)and the whole countryside(72.10/105).YPLL rate declined remar kedly(P<0.01).Both its range and speed exceeded the level of the mortality declined.ConclusionThe death caused by accidental injury was the key cause that affected people's health,but it had smaller effect on life lost.
