目的分析成都市户籍人口期望寿命的变化,探讨不同年龄和死因对期望寿命变化产生的影响。方法利用1990-2010年成都市死因监测户籍人群的死亡数据,和公安局公布的同期同范围人口数,采用寿命表法计算户籍人口期望寿命,采用期望寿命的年龄分解法、期望寿命的死因分解法计算年龄别死亡率和死因别死亡率的变化对期望寿命变化的影响。结果成都市户籍人口期望寿命在提高,男女性别差异扩大;低年龄组死亡率的变化对期望寿命变化的影响逐渐减小,高年龄组死亡率变化对期望寿命变化影响增大;对期望寿命变化影响较大的疾病主要是如呼吸系统疾病、恶性肿瘤、脑血管病、心脏病等。结论降低高年龄组死亡率,加强对呼吸系统疾病、恶性肿瘤、脑血管病、心脏病的控制,降低其死亡率,有助于提高期望寿命。
Objective To analyze the change of life expectancy of the census register in Chengdu and to explore the influence of different age and cause of death on the change of life expectancy.

The change of mortality rate in high age group had an impact on the change of life expectancy. Major diseases such as respiratory diseases, malignant tumors, cerebrovascular disease, heart disease and so on. CONCLUSIONS: Reduce the mortality rate of the high age group and strengthen the control of respiratory diseases, malignant tumors, cerebrovascular diseases and heart diseases, reduce their mortality and help to increase their life expectancy.
