2004-2020 Trends Of Mortality And Premature Death Life Loss Of Road Traffic Accidents Among Urban And Rural Residents In Liaoning Province

Objective: The number of Road Traffic Accidents(RTAs)and the resulting injuries(RTIs)have increased significantly,and RTAs have become a major cause of trauma.The purpose of this paper is to analyze the changing trends of mortality and premature death life loss of RTAs in Liaoning Province and to identify the population groups and types of accidents that need to be focused on prevention and control,so as to provide recommendations for RTIs prevention and control.Methods: Data on reported causes of death in 7 cities and 10 counties from 2004-2020 were collected from the Liaoning Provincial Centre for Disease Control and Prevention Vital Registration System,and the traffic accident codes were identified as V01-V89 according to the International Classfication of Diseases-10 th,with population data from the public security departments of each city or county.The crude mortality,standardized mortality,Years of Life Lost(YLL)due to premature death,YLL rate,and Average Years of Life Lost(AYLL)were calculated using EXCEL 2019.The Joinpoint regression analysis model was used to trend the rates and to estimate the Annual Percent Change(APC)and Average Annual Percent Change(AAPC)and their 95% confidence intervals.Results: 1.The RTIs crude mortality rate,standardized mortality rate,YLL rate and AYLL rate of residents in different regions showed a general downward trend.The standardized RTIs mortality rate of urban and rural residents was 10.66/100,000,that of urban residents was 6.81/100,000,and that of rural residents was 20.14/100,000,which was significantly higher in rural areas than in urban areas,about 3 times that of urban areas.2.The RTIs crude mortality rate,standardized mortality rate,YLL rate and AYLL all showed a downward trend in different genders,and the decline was more obvious in males,but relatively gentle in females.The standardized mortality rate of males was 16.76/100 000,and the standardized mortality rate of females was 4.68/100000.Only women have higher AYLL than men.3.The RTIs crude mortality rate in different age groups was significantly different.The crude mortality rate of 60-79 years old group showed a significant upward trend,increasing from 19.76/100 000 in 2004 to 25.32/100 000 in 2020,while the other age groups showed varying degrees of decline.The YLL rate decreased significantly in 0-9,10-19 and 20-39 age groups.The decrease of AYLL in 0-9,40-59 and 80+ age groups was different.4.The RTIs crude mortality rate and standardized mortality rate of different types of residents were significantly different.The crude RTIs death rate of pedestrians was 5.47/100,000,which was the highest and showed the most obvious downward trend,while the crude RTIS death rate of tricyclists and cars showed an upward trend.The YLL rate of pedestrians,motorcycles and bicycles decreased obviously.The AYLL of different types of RTIs decreased significantly.Conclusion: 1.The total standardized mortality,YLL rate,and AYLL of urban and rural residents in Liaoning Province from 2004 to 2020 showed a decreasing trend over time for RTIs.2.Mortality and life expectancy loss due to premature death were significantly higher in rural areas and men than in cities and women.3.The crude mortality was highest and increasing over time in 60-79 years old,and decreasing in other age groups;the YLL rate was increasing in 60-79 years old,and the YLL rate was highest in 20-39 years old but decreasing over time.4.Pedestrian mortality and YLL rate are the highest,followed by motorcycles,cars,pedal cars,and tricycles.AYLL of cars is the highest.5.Rural,male,elderly population,pedestrians and other vulnerable road users should be taken as the key groups of traffic injury intervention.
