Ethnic Mortality differences in Colombia between 1980-2007 and 2008-2015

在哥伦比亚，土著和非洲后裔的平均死亡时间比白人混血儿早，而且原因不同。这意味着传染病死亡和凶杀分别在土著人和黑人中更为常见。这些死亡率差异最近得到了证实；然而，随着时间的推移，种族之间的死亡率差距是越来越大还是越来越小，这一点尚不清楚。由于缺乏对这一问题进行分析的研究，以及按族裔划分的死亡率数据质量较差，阻碍了对这一主题的更深入了解。在我的博士项目中，我建议分析1980-2007年和2008-2015年哥伦比亚不同种族的死亡率差异。1980-2007年期间，族裔变量将采用族裔分类的统计方法进行重构，2008 - 2015年期间，族裔变量可从死亡率登记册中获取。这项研究不仅试图描述每个族裔群体的流行病学概况（死亡年龄的变异性、主要死亡原因和预期寿命），而且还试图使用一种新的方法在死亡率研究中为死者分配种族背景。对于那些种族死亡率数据质量差或无法获得的国家来说，这是一个很好的机会。这项研究的产出将使我们能够更好地了解哥伦比亚的卫生不平等现象，从而制定更有效的公共卫生政策。哥伦比亚国家统计局（DANE）已经为这项研究提供了死亡率数据。

In Colombia, Indigenous and Afro-descendants are dying, on average, earlier than white-mestizo persons and persistently from different causes. This means that deaths from infectious diseases and homicide are more frequent in indigenous and black people respectively. These mortality differences have been recently proved; however, it is unknown whether this mortality gap between ethnic groups is getting larger or smaller over time. The lack of studies that analyse this problem and also the poor quality of mortality data by ethnic group have hindered a greater understanding of this topic.In my Ph.D. project, I propose to analyse the mortality differences by ethnic group in Colombia between 1980-2007 and 2008-2015. For the period 1980-2007 the ethnic variable will be reconstructed with statistical methods of ethnicity classification, and from 2008 to 2015, it can be taken from mortality registers. This study attempts not only to characterize the epidemiological profile of each ethnic group (variability of age at death, mains causes of death, and life expectancy) but also, to use a new methodology to assign the ethnic background to deceased persons in mortality studies. This represents a great opportunity for countries where the ethnic mortality data are of poor quality or are not available. The outputs of this study will allow us to understand better the health inequalities in Colombia, and therefore, to design more effective public health policies. Mortality data for this study were already provided by the Colombian Office for National Statistics (DANE).
