Epidemiological characteristics of injury deaths in Taizhou / 预防医学

ABSTRACT

Objective @#To understand the epidemiological characteristics of injury deaths among residents in Taizhou,and to provide evidence for prevention and control of injury death. @*Methods @#The monitoring data of injury deaths in Taizhou residents from 2010 to 2016 were derived from the Chronic Disease Surveillance Information Management System of Zhejiang Province. Descriptive epidemiological methods were used to analyze injury mortality,cause of death,population characteristics and life lost due to injury. @*Results @#From 2010 to 2016,a total of 26 313 injury death cases were reported in Taizhou,with an average annual injury mortality rate of 63.61/100 000 and a standardized rate of 56.64/100 000; the mortality rate of injury from 2010 to 2016 showed a downward trend year by year（P<0.05）,and the annual change percentage（APC）was -7.1%. The mortality rates of 0-14 years old,15-44 years old,45-64 years old,65 years old and above group were 15.37/100 000,22.45/100 000, 69.64/100 000 and 315.69/100 000. There were statistically significant differences in the mortality rates of residents between different age groups （P<0.05）. Except for there were no statistically significance differences between the mortality rates of 15-44 years old and 0-14 years old in 2013 and 2014（both P>0.008 3）. The mortality rate in each year from 2010 to 2016 were decreased by 0-14 years old,15-44 years old,45-64 years old,65 years old and above group （all P<0.008 3）. The mortality rate of all age groups showed a downward trend year by year（P<0.05）. The top five injury death causes were accidental falls（17.97/100 000）,motor vehicle traffic accidents（13.97/100 000）,drowning（5.59/100 000）,suicide （5.25/100 000）,other accidents and harmful effects（4.50/100 000）,accounting for 84.35% of the total number of deaths. The injury death causes of the 0-14 years old group were mainly drowning,which was 407 cases,accounting for 1.55% of the total number of deaths; for 15-44 years old group and the 45-64 years old group,the main causes were motor vehicle traffic accidents,which were 1 373 and 2 354 cases,accounting for 5.22% and 8.95%,respectively; for 65 years old and above group,the main cause was mainly accidental falls,which was 6 777 cases,accounting for 25.76%. The years of potential life lost （PYLL） due to injury was 328 678 person-years and the years of potential life lost rate （PYLLR） was 7.95‰.@*Conclusion @#The injury mortality rates of Taizhou residents were declined from 2010 to 2016. The mortality rate of elderly residents due to injury were high and accidental falls was the main cause of injury deaths.
