Objective: To estimate the short-run (6-9 months) impact and mediating mechanisms of an intervention providing supplemental income to individuals 70 years and above from the Mexican state of Yucatan on markers of cognitive functioning (immediate and delayed word recall). Method: Regression-adjusted difference-in-differences (DID) analysis using baseline and follow-up data collected at treatment and control sites from an experiment. Results: The intervention improved immediate and delayed recall scores for men and women. We found no effects on diagnoses of dementia risk factors, depression, and activities of daily living (ADLs). The intervention increased health care use and decreased anemia for men and women, and improved food availability for men. The effects on cognitive outcomes were mediated by health care use for both men and women, and food availability for men. Discussion: In low- and middle-income countries, supplemental income for elderly may be an effective strategy to improve cognitive function by increasing food security and health care utilization.

The observed racial/ethnic gap in bank account ownership among older adults is substantial. We investigate socioeconomic, cognitive, and cultural barriers underling it. As additional potential barriers are accounted for, the residual gaps in financial inclusion with respect to Whites are reduced by 19% for blacks and 46% for Hispanics. We find that citizenship and "taste for privacy" play a limited role for both minority groups, while real asset ownership, health, cognitive ability, and cultural hurdles contribute substantially to the gap. For Hispanics, language barriers explain most of the gap, while neighborhood‐level socioeconomic characteristics are more salient for blacks. We also examine how the racial/ethnic composition of couples influences financial decisions. We estimate a significantly smaller residual gap between "mixed" and white couples than between minority and white couples. We provide empirical evidence suggesting that, other things equal, mixed couples are less concerned with the cultural/psychological barriers facing minority couples. [ABSTRACT FROM AUTHOR]

Labor force participation among Mexican males in their early retirement years (60–64 years of age) has decreased in recent decades, from 94.6% in 1960 to 65.2% in 2010. Similar trends are evident elsewhere in Latin America, and have occurred in the developed world. Such trends pose challenges to the financial sustainability of social security systems as working-age populations decrease and those in retirement increase both because of demographic trends and decisions to take early retirement. In this study, we find that the Mexican social security system provides incentives to retire early. The retirement incentives of the Mexican social security system affect retirement behavior, and may be one of the main contributors to early retirement decisions, particularly for lower-income populations. We simulated the effect of the reform from a pay-as-you-go to the new Personal Retirement Accounts (PRA) system and we find that the PRA system also provides incentives for early retirement. Further analysis is needed to assess the financial sustainability of the social security system and financial security in old age for the largest cohorts in Mexico that will begin to retire by 2040.

The Mexican Health and Aging Study (MHAS) is a longitudinal study using a national sample of approximately 15,000 community-dwelling adults aged 50 years old and older in Mexico. Spanning over 20 years (2001-2021), six waves of data collection establish the MHAS as the leading data platform for the study of aging in Latin America.

Objective: We developed a MHAS (Mexican Health and Aging Study) and O*NET (Occupational Information Network) linkage to allow global researchers using MHAS data to assign lifetime occupation domains for older Mexicans., Materials and Methods: Three bilingual raters independently matched 440 records with 132 unique occupation codes from the 2012 MHAS. We used a modified Delphi technique to reach agreements. To assess reliability, we compared the distribution of observations between the MHAS file and the MHAS-O*NET linked file across five job categories (upper white collar, lower white collar, upper blue collar, low blue collar, and agriculture/fishing/forestry). The Institutional Review Board at the University of Texas Medical Branch reviewed and approved the research (IRB # 21-0268)., Results: Using the developed 1:1 MHAS-ONET linkage, consistency between MHAS and ONET was 97.4% across the five job categories., Conclusion: This MHAS-O*NET linkage will allow researchers to analyze the association between lifetime occupation and multiple dimensions of health, functionality, and retirement determinants for a low-middle income country with a large proportion of workers in the informal sector.

Introduction: Substantial gaps in research remain across oldest-old ethnic populations while the burden of dementia increases exponentially with age among Mexican and Mexican American older adults., Methods: Prevalence and correlates of dementia among individuals ≥82 years of age were examined using two population-based cohort studies: The Mexican Health and Aging Study (MHAS, n = 1078, 2012) and the Hispanic Established Populations for the Epidemiologic Study of the Elderly (HEPESE, n = 735, 2012-2013). The analytic MHAS and HEPESE samples had an average age of 86.4 and 88.0 years, 1.2 and 1.8 women to men, and 2.7 and 5.1 average years of education, respectively., Results: We identified 316 (29.2%) and 267 (36.3%) cases of likely dementia in the MHAS and HEPESE cohorts, respectively. For Mexicans but not Mexican Americans, age-adjusted prevalence rates of likely dementia were higher in women than men. For both populations prevalence rates increased with age and decreased with education for Mexican Americans but not for Mexicans. In both populations, odds of likely dementia increased with age. Health insurance for the low-income was significantly associated with higher odds of likely dementia for Mexican American men and women and Mexican women but not men. Living in extended households increased the odds of likely dementia in women, but not in men for both studies. Multiple cardiovascular conditions increased the odds of likely dementia for Mexicans but not for Mexican Americans., Discussion: Our study provides evidence of the high burden of dementia among oldest-old Mexicans and Mexican Americans and its association with health and social vulnerabilities., Competing Interests: The authors have no conflicts of interest to report., (© 2020 The Authors.
