成都市近20年户籍人口期望寿命变化

Life Expectancy Change of Chengdu Residents in Last 20 Years

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 Chengdu residents life expectancy in the last 20 years,and explore the influence of ages and diseases on the life expectancy change.Methods Deaths data from Chengdu residents cause of death monitoring during 1990-2010;population in the same period and same range announced by the Public Security Bureau were collected;resident life expectancy was calculated by using life-table method;age-specific mortality and cause-specific mortality changes on the impact of changes in life expectancy were calculated by using life expectancy of age decomposition method and life expectancy of death decomposition method.Results The life expectancy of Chengdu residents was growing,and the difference between males and females was expanded.The contribution of children on the life expectancy was reducing;while it was increasing in the middle age and elderly adults.Respiratory diseases,cancer and circulation diseases were important in contribution of life expectancy.Conclusion In order to increase the life expectancy of Chengdu residents,we should take measures to improve the health of middle-aged and elderly populations;and reduce the death of respiratory diseases,cancer,circulation diseases,etc.
