Abstract
OBJECTIVE: 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. METHOD: We employ the Hispanic Established Populations for Epidemiologic Studies of the Elderly (H-PESE) to control for mortality-related health and social factors. RESULTS: 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. CONCLUSION: 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.
