Life expectancy at birth is a synthetic mortality indicator that reflects the general living conditions of the population. Changes in mortality by age and causes of death generate no explicit changes in the indicator. The application of a decomposition method can bring light to the analysis of the phenomenon. The aim of this study was to estimate the contribution of age groups and causes of death in the variation in life expectancy at birth, for men and women, from 2000 to 2010, by applying Pollard's decomposition method. Brazilian life tables were obtained from IBGE and death data from SIM. The results indicate that the age group that most contributed to the increase in life expectancy was of less than 1 year old. Among the defined causes, cardiovascular diseases were responsible for the largest increase in life expectancy.
出生时预期寿命是一个综合死亡率指标，反映了人口的总体生活状况。按年龄和死因划分的死亡率变化不会在该指标中产生明显变化。应用分解方法可以为该现象的分析提供线索。本研究的目的是通过应用波拉德分解方法，估计2000年至2010年男性和女性出生时预期寿命变化中各年龄组和死因的贡献。巴西生命表来自巴西地理与统计研究所（IBGE），死亡数据来自信息管理系统（SIM）。结果表明，对预期寿命增加贡献最大的年龄组是1岁以下。在确定的死因中，心血管疾病导致预期寿命增加最多。
