Abstract

Latin American countries are undergoing major changes in their mortality profiles due to unique epidemiological and health transitions in the region. The main goal of this paper is to study the evolution of the mortality age profiles and the distribution of age at death for a series of Latin America countries in order to identify the effects of mortality changes on the variability of age at death. We use data from different and alternative sources (who, lahmd, and lambda) to study this issue in the region. We first evaluate the quality of national-level mortality data overtime in Latin American countries. Using a relational model, we estimate the mortality patterns by single year age-groups, for each country in Latin America. Lastly, we use traditional metrics of age at death variability to perform the analysis. Our results indicate that the quality of mortality data is improving over time for all countries we include. We also find a decrease in variability of age at death, and that the decrease has happened faster for females than for males. In recent years, increasing mortality due to external causes of deaths related to violence, have reduced the rise in life expectancy at birth and increased the variability in the age at death for several countries in the region. These results contribute to the study of mortality changes in Latin America looking at mortality compression and the variability of age at death. Over the last half-century there has been a reduction in the variability of age at death, but more recently, increases in external causes of death have been associated with a stagnation in the compression process. The analysis also provides some insight and questions about morbidity trends in the region
死亡率压缩:拉丁美洲死亡年龄变异性的演变
由于该地区独特的流行病学和健康转型,拉丁美洲国家的死亡率正在发生重大变化。本文的主要目标是研究一系列拉丁美洲国家的死亡率年龄分布和死亡年龄分布的演变,以确定死亡率变化对死亡年龄变异性的影响。我们使用来自不同和替代来源(世卫组织、lahmd和lambda)的数据来研究该地区的这一问题。我们首先评估了拉丁美洲国家的国家级死亡率数据的质量。使用关系模型,我们估计了拉丁美洲每个国家按单年年龄组的死亡率模式。最后,我们使用传统的死亡年龄变异性指标来进行分析。我们的研究结果表明,随着时间的推移,包括我们在内的所有国家的死亡率数据质量都在提高。我们还发现,死亡时年龄的变异性下降,而且女性的下降速度比男性快。近年来,与暴力有关的外部死亡原因导致的死亡率不断上升,降低了该地区几个国家出生时预期寿命的增长,并增加了死亡年龄的可变性。这些结果有助于研究拉丁美洲的死亡率变化,即死亡率压缩和死亡年龄的可变性。在过去的半个世纪里,死亡年龄的可变性有所降低,但最近,外部死亡原因的增加与压缩过程的停滞有关。该分析还提供了有关该地区发病率趋势的一些见解和问题
