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.
