Abstract

Abstract

Objective To analyze characteristics of the main injury-induced death and life loss among Shenzhen residents during 2017-2020 and provide a scientific basis for the targeted formulation of strategies and measures for injury prevention and control. Methods Injury-induced death characteristics and life loss were assessed using composition ratio, mortality rate, standardized mortality rate, potential years of life lost (PYLL), potential years of life lost rate (PYLLR), and average years of life lost (AYLL). Joinpoint regression was also applied to compare the age-specific mortality rates of significant injury death causes in different years and genders. Results The number of injury-induced deaths among Shenzhen residents in 2017-2020 was 7 199, with an average annual crude mortality rate of 12.73/100 000 and an average annual standardized mortality rate of 20.70/100 000, the mortality rate of males was higher than females. The top three causes of injury-induced death and injury-induced PYLL were suicide, traffic accident and accidental fall. The overall change in the age-specific mortality rate of all injury-induced in the whole population was a mean increase of 4.9% per year (t=5.2, P < 0.001);the overall suicide mortality rate was a mean increase of 3.1% per year (t=3.8, P < 0.001);the overall change of mortality rates for traffic accidents was a mean increase of 2.7% per year (t=2.8, P=0.005);the overall change in mortality rates for falls was a mean increase of 6.1% per year (t=6.8, P< 0.001). The mortality turning points of males and females were different, the mortality curves were not parallel, and the trends were not the same. The total PYLL caused by injuries during the 4-year period was 269 093.5 person-years, the AYLL was 37.38 years/person, and the PYLLR was 4.76 per 1 000. Conclusion Suicide is the primary cause of injury-induced death among Shenzhen residents, and the mortality rates of each cause of injury-induced death for men and women show different age trends. Targeted measures should be taken according to critical populations. Injuries lead to serious life loss and have a significant impact on families and society. All sectors of society need to strengthen the prevention of injuries and reduce the occurrence of injuries, especially fatal injuries.
