This study tested a healthy immigrant effect (HIE) and postimmigration health status changes among late life immigrants.
Using three waves of the Second Longitudinal Study of Aging (1994-2000) and the linked mortality file through 2006, this study compared (a) chronic health conditions, (b) longitudinal trajectories of self-rated health, (c) longitudinal trajectories of functional impairments, and (d) mortality between three groups (age 70+): (i) late life immigrants with less than 15 years in the United States (n = 133), (ii) longer term immigrants (n = 672), and (iii) U.S.-born individuals (n = 8,642). Logistic and Poisson regression, hierarchical generalized linear modeling, and survival analyses were conducted.
Late life immigrants were less likely to suffer from cancer, had lower numbers of chronic conditions at baseline, and displayed lower hazards of mortality during the 12-year follow-up. However, their self-rated health and functional status were worse than those of their counterparts over time.
A HIE was only partially supported among older adults.
本研究旨在检验健康移民效应（HIE）以及移民后健康状况的变化在老年移民中的表现。
本研究使用了三个时间点的第二次老龄化纵向研究（1994-2000 年）和截至 2006 年的相关死亡档案，比较了（a）慢性健康状况，（b）自我评估健康的纵向轨迹，（c）功能障碍的纵向轨迹，以及（d）三组（70 岁以上）的死亡率：（i）在美国居住时间少于 15 年的老年移民（n=133），（ii）长期移民（n=672），以及（iii）美国出生者（n=8642）。采用逻辑回归和泊松回归、分层广义线性模型和生存分析进行了分析。
老年移民患癌症的可能性较低，在基线时有较少的慢性疾病，并且在 12 年的随访期间死亡率较低。然而，他们的自我评估健康和功能状况随着时间的推移比同龄人更差。
老年移民中仅部分支持健康移民效应。
