Abstract: Objective To understand the epidemiological characteristics and trend of injury mortality among children aged 5~19 from 2008 to 2014 in Xi'an city,and to provide evidence for making related interventions. Methods Data were derived from the disease death surveillance database during 2008 to 2014.ICD-10 was used to classify death causes.Mortality rate,proportional mortality indicator and annual percent change(APC) were calculated and analyzed. Results Mortality in injured deaths was 14.01/10⁵,which showed a descending tendency with the average decrease rate of 3.23%.The mortality in boys was higher than that in girls,and the mortality in boys showed a descending tendency(APC=-5.58%,t=-4.04,P<0.05).The first 5 kinds of injury death causes were traffic accidents,drowning,accidents,suicide and accidental poisoning,which accounted for 87.92% of total injury mortality among children aged 5 to 19 years old. Conclusions The injury mortality of children aged 5~19 years old showed a descending tendency.Traffic accidents and drowning are major causes of injury death.The damage prevention and control from family,school and social should be strengthened to reduce the injury mortality of young people.
