Life expectancy is a statistical measure of the average time an organism is expected to live. The purpose of this study was to evaluate the impact of injury-related mortality on life expectancy in Zhejiang Province.
Our study used standard life tables to calculate life expectancy and cause-removed life expectancy based on mortality data from the Zhejiang Chronic Disease Surveillance System.
Life expectancy of residents in Zhejiang was 77.83 years in 2013, with females having a higher life expectancy than males. The decrease in life expectancy caused by injury-related deaths was 1.19 years, the effect of which was reduced for females and urban residents compared with males and rural residents. The greatest impact on life expectancy was road traffic injuries (RTIs), (0.29 years lost overall, 0.36 for men vs. 0.21 for women and 0.26 for urban residents vs. 0.31 for rural residents). The main causes were falls (0.29 years lost overall, 0.30 for men vs. 0.28 for women and 0.28 for urban residents vs. 0.30 for rural residents), followed by drowning (0.15 years lost), suicide (0.11 years lost), and poisoning (0.04 years). For children less than 5 years old and elders aged over 65, drowning had a greater impact than falls.
Our findings indicate that injury deaths had a major impact on life expectancy in Zhejiang. More attention should be paid to road traffic injury, and preventive action should be taken to reduce injury-related deaths to increase life expectancy, especially in children under five years of age and the elders over 65 years of age.
预期寿命是对生物体预期存活的平均时间的一种统计衡量。本研究的目的是评估伤害相关死亡率对浙江省预期寿命的影响。
我们的研究使用标准生命表，根据浙江省慢性病监测系统的死亡率数据计算预期寿命和去除死因后的预期寿命。
2013年浙江省居民的预期寿命为77.83岁，女性的预期寿命高于男性。伤害相关死亡导致的预期寿命减少为1.19岁，与男性和农村居民相比，女性和城市居民的这种影响有所降低。对预期寿命影响最大的是道路交通伤害（RTIs）（总体损失0.29岁，男性为0.36岁，女性为0.21岁，城市居民为0.26岁，农村居民为0.31岁）。主要原因是跌倒（总体损失0.29岁，男性为0.30岁，女性为0.28岁，城市居民为0.28岁，农村居民为0.30岁），其次是溺水（损失0.15岁）、自杀（损失0.11岁）和中毒（损失0.04岁）。对于5岁以下儿童和65岁以上老年人，溺水的影响比跌倒更大。
我们的研究结果表明，伤害死亡对浙江省的预期寿命有重大影响。应更加关注道路交通伤害，并采取预防措施减少与伤害相关的死亡，以提高预期寿命，特别是在5岁以下儿童和65岁以上老年人中。
