Abstract:
Objective:To quantify the impact of injury-related deaths on the gender gap in life expectancy (GGLE).Methods:Abbreviated life table was used to analyse Tianjin residents' cause of death surveillance data from 2003 to 2021, and life expectancy was calculated by gender. SPSS 24.0 software was applied to calculate the injury-standardised mortality rate of Tianjin residents. The Arriaga decomposition method was used to calculate the effects of injury-related deaths on age-specific and urban-rural GGLE in 2003 and 2021.Results:The GGLE in Tianjin from 2003 to 2021 ranged from 2.63 to 4.47 years. Injury mortality rates declined significantly in males and showed no significant change in females. the incremental increase in life expectancy over the 19 years was 0.47 years (13.68%) for males, significantly higher than that for females (0.06 years, 1.09%). The GGLE caused by injury deaths in 2021 (0.34 years, 7.64%) decreased compared with 2003 (0.54 years, 20.40%) and decreased more in rural areas. Compared to 2003, the most significant reduction in the contribution rate of injury deaths on the GGLE was observed in the 5-49 age group in 2021, with a cumulative reduction of 12.11%. The contribution rates of transport accidents excluding motor vehicles, motor vehicle traffic accidents, drowning, accidental poisoning, and electrocution all decreased, with only motor vehicle traffic accidents increasing in rank, taking the first place in the injury contribution rates for 2021. The contribution rate of suicide was significantly higher in the 25-29 age group. The contribution of accidental falls was higher in the 50-79 age group and lower in the ≥85 age group, and that of other accidents and adverse effects was significantly lower in the ≥85 age group.Conclusions:Injury interventions for females in Tianjin should receive more attention, especially in preventing unintentional falls and other accidents and adverse effects among elderly females aged ≥85. Injury prevention for males should not be neglected, and efforts should be made to reduce the mortality rate of motor vehicle traffic accidents among males in rural areas of Tianjin. Attention should be paid to suicide intervention for males, especially those aged 25-29, and to prevent accidental falls among middle-aged and elderly males aged 50-79.
