ABSTRACT

Objective To analyze the change of life expectancy and the impact of mortality by age and causes of death on this issue among permanent residents of Beijing.Methods Abridged Life Table and Arriaga method were used to calculate and to decompose the changes on life expectancy by age and causes of death in 2000-2010.Results From 2000-2010,life expectancy under this studied population had an increase of 3.35 years.Most part of the increases (44.27％,1.48 years) within the last 10 years could be explained by the decrease of mortality in the population at age ≥ 80.Both cerebrovascular and heart diseases were contributing the most to the increment of life expectancy while mortality of malignant tumors appeared a negative contributor to this increment.Conclusion From 2000 to 2010,increment in life expectancy contributed to the decrease of mortality in the elderly and the decrease of mortalities on both cardio-and cerebro-vascular diseases.The decrease of life expectancy was mainly due to the increase of mortality related to malignant tumors.
