In this article, we investigate the association between age at migration and mortality during a 13-year period in a sample of Mexican American immigrants 65 and older at baseline.
We employ the Hispanic Established Populations for Epidemiologic Studies of the Elderly (H-PESE) to control for mortality-related health and social factors.
Our analyses show that the immigrant generation does not represent a homogeneous mortality risk category. Individuals who migrated to the United States in mature adulthood have a considerably lower risk of death than individuals who migrated in childhood or midlife. Chronic conditions or functional capacity do not account for these differences.
Our findings suggest that standard risk pools may differ significantly on the basis of genetic and unmeasured life-course factors. A better understanding of the late-life immigrant mortality advantage has important implications for more effective and targeted social and medical interventions.
本研究旨在探讨 65 岁及以上的墨西哥裔美国移民在 13 年期间内,其移民年龄与死亡率之间的关系。
本研究采用西班牙裔老年人人群队列研究(H-PESE)来控制与死亡率相关的健康和社会因素。
分析结果显示,移民群体并非一个同质的死亡风险类别。相较于儿童期或中年期移民,成年后移民到美国的个体死亡风险显著降低。慢性疾病或功能能力并不能解释这些差异。
我们的研究结果表明,基于遗传和未测量的生命历程因素,标准风险池可能存在显著差异。深入了解晚年移民的死亡优势对更有效和有针对性的社会和医疗干预具有重要意义。
