ABSTRACT

Studies of the current Chilean population performed using classical genetic markers have established that the Chilean population originated primarily from the admixture of European people, particularly Spaniards, and Amerindians. A socioeconomic-ethno-genetic cline was established soon after the conquest. Spaniards born in Spain or Chile occupied the highest Socioeconomic Strata, while Amerindians belonged to the lowest. The intermediate strata consisted of people with different degrees of ethnic admixture; the larger the European admixture, the higher the Socioeconomic Level. The present study of molecular genomic markers sought to calculate the percentage of Amerindian admixture and revealed a finer distribution of this cline, as well as differences between two Amerindian groups: Aymara and Mapuche. The use of two socioeconomic classifications – Class and Socioeconomic Level – reveals important differences. Furthermore, Self-reported Ethnicity (self-assignment to an ethnic group) and Self-reported Ancestry (self-recognition of Amerindian ancestors) show variations and differing relationships between socioeconomic classifications and genomic Amerindian Admixture. These data constitute a valuable input for the formulation of public healthcare policy and show that the notions of Ethnicity, Socioeconomic Strata and Class should always be a consideration in policy development.

智利社会民族基因组

摘要

使用经典遗传标记对当前智利人口进行的研究表明,智利人口主要起源于欧洲人,特别是西班牙人和美洲印第安人的混合体。征服后不久就建立了一个社会经济-民族-遗传学系。在西班牙或智利出生的西班牙人占据了最高的社会经济阶层,而美洲印第安人则属于最低。中间阶层由不同程度的种族混合的人组成;欧洲混合物越大,社会经济水平越高。目前对分子基因组标记的研究试图计算美洲印第安人混合物的百分比,并揭示了该种系的更精细分布,以及两个美洲印第安人群体之间的差异:艾马拉人和马普切人。使用两个社会经济分类——阶级和社会经济水平——揭示了重要的差异。此外,自我报告的种族(自我分配到一个族群)和自我报告的祖先(对美洲印第安人祖先的自我认可)显示了社会经济分类和基因组美洲印第安人混合物之间的差异和不同关系。这些数据构成了制定公共医疗保健政策的宝贵输入,并表明种族、社会经济阶层和阶级的概念应始终是政策制定中的一个考虑因素。自我报告的种族(自我分配到一个族群)和自我报告的祖先(对美洲印第安人祖先的自我认可)显示了社会经济分类和基因组美洲印第安人混合物之间的变化和不同关系。这些数据构成了制定公共医疗保健政策的宝贵输入,并表明种族、社会经济阶层和阶级的概念应始终是政策制定中的一个考虑因素。自我报告的种族(自我分配到一个族群)和自我报告的祖先(对美洲印第安人祖先的自我认可)显示了社会经济分类和基因组美洲印第安人混合物之间的变化和不同关系。这些数据构成了制定公共医疗保健政策的宝贵输入,并表明种族、社会经济阶层和阶级的概念应始终是政策制定中的一个考虑因素。
