ABSTRACT
OBJECTIVES:
We examined the association of generational status and age at immigration with later life cognitive outcomes in a diverse sample of Latinos and Asian Americans.DESIGN:
Baseline data were obtained from the Kaiser Healthy Aging and Diverse Life Experiences (KHANDLE) study, and a prospective cohort is initiated in 2017.SETTING:
Older adults in Northern California.PARTICIPANTS:
Our cohort consisted of Asians (n = 411) and Latinos (n = 340) who were on average 76 years old (SD = 6.8). MEASUREMENTS We used multivariable linear regression models to estimate associations between generational status and age at immigration (collapsed into one five-level variable) with measures of verbal episodic memory, semantic memory, and executive function, adjusting for age, gender, race and ethnicity, and own- and parental education.RESULTS:
Generational status and age at immigration were associated with cognitive outcomes in a graded manner. Compared to third-generation or higher immigrants, first-generation immigration in adulthood was associated with lower semantic memory (ß = -0.96; 95% CI -1.12, -0.81) than immigration in adolescence (ß = -0.68; 95% CI -0.96, -0.41) or childhood (ß = -0.28; 95% CI -0.49, -0.06). Moreover, immigration in adulthood was associated with lower executive function (ß = -0.63; 95% CI -0.78, -0.48) than immigration in adolescence (ß = -0.49; 95% CI -0.75, -0.23). Similarly, compared to third-generation individuals, first-generation immigrants had lower executive functioning scores.CONCLUSIONS:
Our study supports the notion that sociocontextual influences in early life impact later life cognitive scores. Longitudinal studies are needed to further clarify how immigration characteristics affect cognitive decline.Palavras-chave
