This study investigates whether immigrant status is a risk factor for developing dementia and having undiagnosed dementia, as well as the role of limited English proficiency (LEP) as a mediator in the association. Data were drawn from the 2011 wave of the National Health and Aging Trends Study. The sample consisted of 7385 adults aged 65 years and older (6567 U.S.-born and 818 foreign-born). Step-wise logistic regression analyses were performed. Older immigrants had 70% greater odds of having dementia compared to U.S.-born participants. Among those with dementia (n = 1920), older immigrants showed 119% higher odds of being undiagnosed compared to the U.S.-born. Mediation analyses showed that the total effects of immigrant status on dementia and undiagnosed dementia explained by LEP were 87.6% and 56.1%, respectively. It is important to tailor dementia education and interventions to the immigrant population with LEP.
本研究调查了移民身份是否是导致痴呆症和未被诊断的痴呆症的风险因素，以及英语水平有限（LEP）作为中介在这种关联中的作用。数据来自 2011 年国家健康老龄化趋势研究的调查。样本由 7385 名年龄在 65 岁及以上的成年人组成（6567 名美国出生和 818 名外国出生）。逐步逻辑回归分析。与美国出生的参与者相比，老年移民患痴呆症的几率增加了 70%。在患有痴呆症的患者中（n=1920），与美国出生的患者相比，老年移民未被诊断出的几率高 119%。中介分析表明，LEP 解释的移民身份对痴呆症和未被诊断的痴呆症的总影响分别为 87.6%和 56.1%。重要的是，要针对有 LEP 的移民人群量身定制痴呆症教育和干预措施。
