Age Trajectories of Physical Health Among Older Adults of Mexican Descent: Implications of Immigrant Status, Age at Immigration, and Gender

Aging into disadvantage: Disability crossover among Mexican immigrants in America

The "Hispanic paradox" refers to the accepted finding that Mexican immigrants have lower mortality compared to the US-born population, despite having lower levels of income, educational attainment, and health insurance coverage. However, Mexican immigrants' mortality advantage is not matched by lower disability rates, particularly later in the life course. Past studies have identified a crossover in disability rates for Mexican immigrants using age-specific disability rates but confound the effects of aging and duration of residence. By using the synthetic cohort method, I extend prior work on the disability crossover by tracing immigrant cohorts across the life course and disentangling newly arrived immigrants from those already established in the U.S. I use American Community Survey (ACS) 2015-2019 data to test whether the acculturation or cumulative disadvantage hypotheses account for the disability crossover. I find that, contrary to the expected finding of a socioeconomic health gradient in disability rates, Mexican immigrants' high disability rates converge regardless of education level or immigrant cohort. In addition, Mexican female immigrants are doubly disadvantaged, living in a protracted period of disability compared to males of the same education level. My findings support the negative health acculturation hypothesis as the dominant pathway for Mexican immigrants' later-life disability trajectories and consequently the explanation behind the disability crossover.

Acculturation strategies, age at migration, and self-rated health: An empirical study on internal migrants in China

Berry's bidimensional acculturation model categorizes acculturation status (integration, assimilation, separation, marginalization) by preference toward host and origin cultures. According to Berry's theory, different acculturation strategies yield different health outcomes, and age at migration moderates the relationship between acculturation and health outcome. Previous research has applied this model to understand acculturation's influence on international migrants' health outcomes, but rarely for internal migrants. This research examines these relationships using a national survey on Chinese internal migrants. Using propensity score weighting, the results align with previous findings that integration strategy-using migrants reported optimal health status, separation/assimilation strategy-using migrants reported suboptimal health, and marginalization strategy-using migrants reported the worst health, suggesting the model can explain health disparities among internal migrants. Moreover, older age at migration deteriorates health outcomes and moderates health disparities among migrants employing different acculturation strategies. However, age at migration's moderating effect is significant only among inter-provincial migrants. Embracing the host society inhibits health deterioration among inter-provincial migrants with older age at migration, whereas rejecting or embracing both societies facilitates health deterioration among intra-provincial migrants.

Gender and Age of Migration Differences in Mortality Among Older Mexican Americans

OBJECTIVES

Using a gendered life course perspective, we examine whether the relationship between age of migration and mortality is moderated by gender among a cohort of older Mexican Americans.

METHODS

Data from the Hispanic Established Populations for the Epidemiological Study of the Elderly and recently matched mortality data are used to estimate Cox proportional hazard models.

RESULTS

Our findings indicate that the relationship between age of migration and mortality is moderated by gender, suggesting a more nuanced perspective of the immigrant mortality paradox. Among men, midlife migrants exhibit an 18% lower risk of mortality compared to their U.S.-born co-ethnics, possibly due to immigrant selectivity at the time of migration. Conversely, late-life migrant women exhibit a 17% lower risk of mortality relative to U.S.-born women, attributed in part to socio-cultural characteristics that influence lifestyle risk factors across the life course.

DISCUSSION

Selection mechanisms and acculturation processes associated with the immigrant experience are contingent on both age and gender, suggesting the utility of an integrated life course approach to contextualize the mortality profiles of older immigrants. These findings demonstrate the heterogeneity among immigrants and highlight the need to understand gender differences in the migration process when assessing the immigrant mortality paradox.

Does the healthy immigrant effect apply to mental health? Examining the effects of immigrant generation and racial and ethnic background among Australian adults

The healthy immigrant effect (HIE) refers to the phenomena in which immigrants show greater health outcomes than the native-born population. However, it is unclear what is the extent to which HIE applies to various outcomes and populations. Much of the work on HIE has revolved around physical health outcomes; mental health, however, has not garnered the same level of attention with regard to HIE. It is also uncertain whether immigrants’ health advantage persists beyond one generation. This study assesses the mental health of the first, second, and third and higher generations (70,517 person-year observations) for individuals from various racial and ethnic backgrounds in Australia using Waves 1−16 of the Household Income and Labour Dynamics in Australia survey. The dependent variable is mental health score and key independent variables include generation and racial and ethnic background. I control for age, educational attainment, labor force status, marital status, remoteness, household income, language, neighborhood disadvantage, citizenship, weight, and gender. Using linear regression with random effects, this study finds that mental health varies by generation; the third and higher generation show the greatest mental health score, followed by the first generation and the second generation, net of controls. Mental health score also varies by racial and ethnic background. Except for English-speaking groups, native-born Australians show a clear advantage over Europeans, North Africans/Middle Easterners, and Asians. Racial and ethnic disparities differ by generation and are strongest among the first generation. My findings extend HIE, which typically emphasize immigrants’ superior health outcomes over the native-born population but do not focus on racial and ethnic disparities among immigrants. My results suggest that immigrant groups vary widely in their mental health outcomes but these lessen over time. Overall, the findings suggest the limited applicability of HIE for a broad range of health outcomes and populations.

•

The third and higher generation have the highest mental health scores, followed by the first and second generations.

•

The first generation's mental health scores are associated with relatively fewer factors relative to the second and third and higher generations.

•

English-speaking groups show the highest mental health followed by native-born Australians.

•

All other minority groups show lower mental health scores.

•

Racial and ethnic disparities in mental health differ by generation.

Factors Associated With Physical Performance Measures in a Multiethnic Cohort of Older Adults

Objective: To explore the association between ethnicity, sociodemographic, health, and lifestyle factors, and physical performance (PP) in ethnically diverse community-dwelling older adults from one geographic area. Method: We used multivariable linear regression to identify factors associated with upper (grip strength [GS], arm curls [AC]) and lower (chair stands [CS]) body strength and mobility (gait speed [GSp]) in 577 older adults (mean age 74 ± 8; 104 African American, 142 Afro-Caribbean, 123 Hispanic, and 208 European American) from South Florida. Results: Worse mental health was negatively associated with CS in African Americans and AC in Hispanics. Older age and higher body mass index (BMI) was associated with slower GSp in all except in Hispanics. Higher physical activity was associated with higher upper body strength in Hispanics and better mobility in African Americans and Afro-Caribbeans, but not in European Americans. Conclusion: Studies with large multiethnic cohorts are needed to further our understanding of ethnic differences in PP, which will help in tailoring interventions and recognizing unmet needs for health and social services.
