To analyze the impact of injury mortality changes on life expectancy (LE) in Tianjin in 2021 compared with 2003 by age, gender, urban-rural, and cause-specific differences.
The abridged life table and Arriaga's decomposition method were applied to analyze the cause of death surveillance data of Tianjin residents in 2003 and 2021, calculating the age-specific and subcategory-specific contribution of injury to the increase of LE.
From 2003 to 2021, the injury mortality rate dropped from 30.33 to 21.57 per 100,000 in Tianjin. Over this period, LE varied from 77.70 to 82.03 years, with an increase of 4.33 years. The reduction in injury mortality contributed 0.3111 years (7.18 %) to the growth of LE. The positive impact on LE was notably observed in the age group of 1-49 years, contributing 0.4348 years (10.04 %) cumulatively. The major injuries that contributed significantly to the increase of LE were transport accidents excluding motor vehicles (0.2558 years, 5.91 %), accidental poisoning (0.0845 years, 1.95 %), motor vehicle traffic accidents (0.0474 years, 1.09 %), and drowning (0.0359 years, 0.83 %). However, the rise in intentional self-harm mortality rate from ages 10-24 and increased mortality rates due to other accidents and adverse effects, motor vehicle traffic accidents, and falls from ages 50+ had negative impacts on LE.
During 2003-2021, the decline in injury mortality rates among children and young to middle-aged individuals in Tianjin played a crucial role in the increase of LE. It is essential to enhance primary prevention efforts, particularly focusing on key populations, to reduce the negative impact on LE growth from intentional self-harm, other accidents and adverse effects, motor vehicle traffic accidents, and falls.
分析 2021 年与 2003 年相比，天津市因年龄、性别、城乡和死因不同导致的伤害死亡率变化对预期寿命（LE）的影响。
应用简略寿命表和 Arriaga 分解法分析 2003 年和 2021 年天津市居民死因监测数据，计算伤害对 LE 增长的年龄别和亚类别的贡献。
2003 年至 2021 年，天津市伤害死亡率从 30.33/10 万下降至 21.57/10 万。在此期间，LE 从 77.70 岁增加到 82.03 岁，增加了 4.33 岁。伤害死亡率的降低对 LE 的增长贡献了 0.3111 岁（7.18%）。1-49 岁年龄组对 LE 的正向影响最为显著，累计贡献 0.4348 岁（10.04%）。对 LE 增长贡献较大的主要伤害为不含机动车的交通伤害（0.2558 岁，5.91%）、意外中毒（0.0845 岁，1.95%）、机动车交通事故（0.0474 岁，1.09%）和溺水（0.0359 岁，0.83%）。然而，10-24 岁人群的故意伤害死亡率上升以及 50 岁以上人群的其他事故和不良后果、机动车交通事故和跌倒导致的死亡率上升，对 LE 产生了负面影响。
2003-2021 年，天津市儿童和中青年伤害死亡率的下降对 LE 的增长起到了关键作用。需要加强初级预防工作，特别是针对关键人群，以减少故意伤害、其他事故和不良后果、机动车交通事故和跌倒对 LE 增长的负面影响。
