Inequalities in Disability-Free and Disabling Multimorbid Life Expectancy in Costa Rica, Mexico, and the United States.

OBJECTIVES: To better understand variations in multimorbidity severity over time, we estimate disability-free and disabling multimorbid life expectancy (MMLE), comparing Costa Rica, Mexico, and the United States (US). We also assess MMLE inequalities by sex and education. METHODS: Data come from the Costa Rican Study on Longevity and Healthy Aging (2005-2009), the Mexican Health and Aging Study (2012-2018), and the Health and Retirement Study (2004-2018). We apply an incidence-based multistate Markov approach to estimate disability-free and disabling MMLE and stratify models by sex and education to study within-country heterogeneity. Multimorbidity is defined as a count of 2 or more chronic diseases. Disability is defined using limitations in activities of daily living. RESULTS: Costa Ricans have the lowest MMLE, followed by Mexicans, then individuals from the US. Individuals from the US spend about twice as long with disability-free multimorbidity compared with individuals from Costa Rica or Mexico. Females generally have longer MMLE than males, with particularly stark differences in disabling MMLE. In the US, higher education was associated with longer disability-free MMLE and shorter disabling MMLE. We identified evidence for cumulative disadvantage in Mexico and the US, where sex differences in MMLE were larger among the lower educated. DISCUSSION: Substantial sex and educational inequalities in MMLE exist within and between these countries. Estimating disability-free and disabling MMLE reveals another layer of health inequality not captured when examining disability and multimorbidity separately. MMLE is a flexible population health measure that can be used to better understand the aging process across contexts.

The Effect of Financial Strain on the Health Outcomes of Older Mexican-Origin Adults: Findings From the Hispanic Established Population for the Epidemiological Study of the Elderly (H-EPESE).

Predictors of health across the life-course do not maintain the same significance in very late life and the role of financial strain in health outcomes of very old adults remain unclear. Data from adults aged 74 + in waves 5 and 7 of the Hispanic Established Population for the Epidemiological Study of the Elderly (n = 772) study was used to evaluate the role of financial strain on the health of older Mexican Americans who have the highest poverty rate of any racial or ethnic group in the United States. We evaluate the association between episodic (one wave) and persistent financial strain (two waves), with follow-up health outcomes (self-rated health, ADL (limitations in activities of daily living)/IADL (limitations in instrumental activities of daily living) disability, and depressive symptoms). Adults with persistent strain were twice as likely to experience depressive symptoms and three times more likely to experience IADL limitations than the unstrained. Our findings highlight the role of stress proliferation and allostatic load processes leading to deteriorated health over time.

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.

Cumulative Dis/Advantage and Health Pattern in Late Life: A Comparison between Genders and Welfare State Regimes.

This study provides a cross-national perspective to apply Cumulative Dis/Advantage (CDA) in explaining health inequality between developing and developed countries in the context of Welfare State Theory. Cross-sectional data from the international Health Retirement Study (United States, China, Mexico, and England) in 2013-2014 were used (n = 97,978). Four health indicators were included: self-reported health, depressive symptoms, functional ability, and memory. Regression models were fitted to examine the moderation roles of country and gender. Results indicated older Chinese and Mexican had poorer health status than their British and American counterparts consistently except for Mexicans' memory. Cumulative health gaps between developing and developed countries existed only for functional ability. There is no evidence of a widening gap in health status between genders in late life. CDA explains the increasing gaps of functional ability across age groups between countries. General health and mental health, may however, depend more on individuals' intrinsic capacity and human agency.

Lifetime Socioeconomic Status and Late-life Health Trajectories: Longitudinal Results From the Mexican Health and Aging Study.

Objective: This article examines the association between childhood and adult socioeconomic status (SES) and late-life health trajectories for older adults in Mexico. Method: Data are from the Mexican Health and Aging Study, a panel survey that began with a nationally representative sample of Mexican adults 50 years and older at baseline (2001), with follow-up in 2003 and 2012. We use a hierarchical repeated measures model to estimate the relationship between SES and depressive symptoms, functional limitations, and self-rated health, respectively. We tested both discrete measures of SES in childhood and adulthood, as well as a combined indicator of lifetime SES. Results: Childhood SES was significantly associated with later-life health trajectories net of adulthood SES indicators. Adult SES was significantly associated with late-life health trajectories, with some differences by gender and outcome. There were significant SES disparities in health outcomes over the 11-year study period. However, there were no significant multiplicative interactions between SES and age, which would have indicated either diminishing or widening SES health disparities with age. Discussion: Socioeconomic disparities in health appear to persist into old age in the Mexican context. Efforts to reduce late-life health disparities in Mexico should target socioeconomic and material conditions across the life course.
