RESUMEN

OBJECTIVE: Older adults have heterogeneous aging rates. Here, we explored the impact of biological age (BA) and accelerated aging on frailty in community-dwelling older adults. METHODS: We assessed 735 community-dwelling older adults from the Coyocan Cohort. BA was measured using AnthropoAge, accelerated aging with AnthropoAgeAccel, and frailty using both Fried's phenotype and the frailty index. We explored the association of BA and accelerated aging (AnthropoAgeAccel ≥0) with frailty at baseline and characterized the impact of both on body composition and physical function. We also explored accelerated aging as a risk factor for frailty progression after 3-years of follow-up. RESULTS: Older adults with accelerated aging have higher frailty prevalence and indices, lower handgrip strength and gait speed. AnthropoAgeAccel was associated with higher frailty indices (ß=0.0053, 95%CI 0.0027-0.0079), and increased odds of frailty at baseline (OR 1.16, 95%CI 1.09-1.25). We observed a sexual dimorphism in body composition and physical function linked to accelerated aging in non-frail participants; however, this dimorphism was absent in pre-frail/frail participants. Accelerated aging at baseline was associated with higher risk of frailty progression over time (OR 1.74, 95%CI 1.11-2.75). CONCLUSIONS: Despite being intertwined, biological accelerated aging is largely independent of frailty in community-dwelling older adults.

RESUMEN

Osteoporosis (OP) is a chronic disease that affects older adults' quality of life, with fragility fractures (FF) being its most significant consequence due to their impact on healthcare systems in terms of morbidity, and economic and caregiving burden. FF are defined as fractures resulting from low-energy trauma, defined as falls from a standing height or less, and are usually considered osteoporotic (1). World demographic projections warn of a significant increase in adults aged 65 and older by 2050. These demographic changes mean that OP and FF will soon become an even greater challenge for healthcare systems, where prevention programs should be a priority. In Mexico, FF is also a public health challenge, with an initial reported incidence of nearly 2,000 cases per 100,000 population, and a projected seven-fold increase by 2050. Given this scenario, there is an urgent need for policy- and decision-makers to change their approach and formulate health policies that guarantee that people aged 65 and older are screened for fractures and have access to appropriate care. These policies should be part of a strategy to minimize FF and ensure active and healthy aging according to the WHO's Decade of Healthy Ageing. In this context, a group of Mexican experts representing different health organizations interested in the burden of OP and FF met to discuss possible strategies to reduce their burden for the next decade and summarize them in this Call to Action to promote public policies that prioritize an evidence-based approach to the prevention and treatment of OP and FF.

RESUMEN

BACKGROUND: The Decade of Healthy Aging (2021-2030) emerges as a 10 years strategy to improve the lives of older adults, their families, and the communities in which they live. One of the actions defined in this framework is related to improving the measurement, monitoring, and understanding of characteristics, factors, and needs related to aging and health. The aim was to analyze and assess the process of construction and development of the Strategic Information System on Health, Funcional Dependence and Aging (SIESDE, for its acronym in Spanish). SIESDE will provide strategic information in Mexico at the municipal, state, and national levels that support the public policies on healthy aging. METHODS: The system processes and analyzes the data sources of the Health Information Systems and the National System of Statistical and Geographical Information. SIESDE comprises three components: (1) Design, construction, and evaluation of the indicators; (2) storage, management, and visualization, and (3) diffusion and translation of information. RESULTS: A total of 135 indicators were built on seven themes: (1) demographic, socioeconomic, and aging conditions, (2) health, (3) functional dependence, (4) healthy aging, (5) health services, (6) social and physical environments, and (7) complex indicators. CONCLUSIONS: SIESDE is an effective system for providing an overall view of health, aging, and functional dependence.

RESUMEN

OBJECTIVE: To validate AnthropoAge, a new metric of biological age (BA), for prediction of all-cause mortality and age-related outcomes and characterize population-specific aging patterns using multinational longitudinal cohorts. METHODS: We analyzed harmonized multinational data from the Gateway to Global Aging, including studies from the US, England, Mexico, Costa Rica, and China. We used body mass index and waist-to-height ratio to estimate AnthropoAge and AnthropoAgeAccel in participants aged 50-90 years old as proxies of BA and age acceleration, respectively. We compared the predictive capacity for all-cause mortality of AnthropoAge and chronological age (CA) using Cox models, described aging trends in all countries and explored the utility of longitudinal assessments of AnthropoAgeAccel to predict new-onset functional decline and age-related diseases using generalized estimating equations (GEE). FINDINGS: Using data from 55,628 participants, we found AnthropoAge (c-statistic 0.772) outperformed CA (0.76) for prediction of mortality independently of comorbidities, sex, race/ethnicity, education, and lifestyle; this result was replicated in most countries individually except for Mexico. Individuals with accelerated aging had a ~39% higher risk of death, and AnthropoAge also identified trends of faster biological aging per year. In longitudinal analyses, higher AnthropoAgeAccel values were independently predictive of self-reported health deterioration and new-onset deficits in basic/instrumental activities of daily living (ADL/IADL), diabetes, hypertension, cancer, chronic lung disease, myocardial infarction, and stroke. CONCLUSIONS: AnthropoAge is a robust and reproducible BA metric associated with age-related outcomes. Its implementation could facilitate modeling trends of biological aging acceleration in different populations, although recalibration may enhance its utility in underrepresented populations such as individuals from Latin America.

RESUMEN

BACKGROUND: Older adults are increasingly susceptible to prolonged illness, multiple chronic diseases, and disabilities, which can lead to the coexistence of multimorbidity and frailty. Multimorbidity may result in various noncommunicable disease (NCD) patterns or configurations that could be associated with frailty and death. Mortality risk may vary depending on the presence of specific chronic diseases configurations or frailty. METHODS: The aim was to examine the impact of NCD configurations on mortality risk among older adults with distinct frailty phenotypes. The population was analyzed from the Costa Rican Longevity and Healthy Aging Study Cohort (CRELES). A total of 2,662 adults aged 60 or older were included and followed for 5 years. Exploratory factor analysis and various clustering techniques were utilized to identify NCD configurations. The frequency of NCD accumulation was also assessed for a multimorbidity definition. Frailty phenotypes were set according to Fried et al. criteria. Kaplan‒Meier survival analyses, mortality rates, and Cox proportional hazards models were estimated. RESULTS: Four different types of patterns were identified: 'Neuro-psychiatric', 'Metabolic', 'Cardiovascular', and 'Mixt' configurations. These configurations showed a higher mortality risk than the mere accumulation of NCDs [Cardiovascular HR:1.65 (1.07-2.57); 'Mixt' HR:1.49 (1.00-2.22); ≥3 NCDs HR:1.31 (1.09-1.58)]. Frailty exhibited a high and constant mortality risk, irrespective of the presence of any NCD configuration or multimorbidity definition. However, HRs decreased and lost statistical significance when phenotypes were considered in the Cox models [frailty + 'Cardiovascular' HR:1.56 (1.00-2.42); frailty + 'Mixt':1.42 (0.95-2.11); and frailty + ≥ 3 NCDs HR:1.23 (1.02-1.49)]. CONCLUSIONS: Frailty accompanying multimorbidity emerges as a more crucial indicator of mortality risk than multimorbidity alone. Therefore, studying NCD configurations is worthwhile as they may offer improved risk profiles for mortality as alternatives to straightforward counts.

RESUMEN

Respiratory syncytial virus (RSV) is a significant global health concern and major cause of hospitalization, particularly among infants and older adults. The clinical impact of RSV is well characterized in infants; however, in many countries, the burden and risk of RSV in older populations are overlooked. In Latin America, there are limited data on RSV epidemiology and disease management in older adults. Therefore, the impact of RSV in this region needs to be addressed. Here, current insights on RSV infections in older populations in Latin America, including those with underlying health conditions, are discussed. We also outline the key challenges limiting our understanding of the burden of RSV in Latin America in a worldwide context and propose an expert consensus to improve our understanding of the burden of RSV in the region. By so doing, we aim to ultimately improve disease management and outcomes of those at risk and to alleviate the impact on healthcare systems.A graphical plain language summary is available with this article.

RESUMEN

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.

RESUMEN

BACKGROUND: Older person's ability to contribute covers contributions divided into five subdomains: assisting friends and neighbours, mentoring peers and younger people, caring for family, engaging in the workforce and voluntary activity. OBJECTIVE: To evaluate the psychometric properties of ability to contribute measurements as a domain of functional ability of older persons using Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology for systematic reviews. METHODS: A systematic search was performed in PubMed, Embase and PsycINFO databases, for observational studies published within the last 10 years. The measurement properties of these ability measures were evaluated against the COSMIN taxonomy. Risk-of-bias assessment was performed using the COSMIN Risk of Bias checklist. RESULTS: Of the 32,665 studies identified, we selected 19, of which the main purpose was to develop or validate an instrument or have related items that measure at least one of the subdomains. None of the instruments contained items that were fully related to the five subdomains, 60% (n = 12) were related to voluntary activities and 15% (n = 3) to mentoring peers and younger people. As for psychometric properties, two studies assessed content validity. Factor analysis was used to evaluate structural validity in 10 studies. Internal consistency was evaluated in 63% of the instruments and Cronbach's alpha ranges from 0.63 to 0.92. No study reported predictive validity. A very limited overview of their scope and limitations for their application was observed. CONCLUSIONS: We found no single instrument measuring all subdomains of ability to contribute. We found several instruments containing items that could indirectly measure some of the subdomains of the ability to contribute.

RESUMEN

Background: Frailty has been recognized as a growing issue in older adults, with recent evidence showing that this condition heralds several health-related problems, including cognitive decline. The objective of this work is to determine if frailty is associated with cognitive decline among older adults from different countries. Methods: We analyzed the baseline the Study on Global Ageing and Adult Health (SAGE), that includes six countries (Ghana, South Africa, Mexico, China, Russia, and India). A cross-section analysis was used to assess how Frailty was related with the Clinical Frailty Scale decision tree, while cognitive decline was evaluated using standardized scores of tests used in SAGE. Results: A total of 30,674 participants aged 50 years or older were included. There was an association between frailty levels and cognitive performance. For example, women had an inverse relationship between frailty levels and cognitive scores, even when comparing robust category with frailty level 2 (RRR = 0.85; p = 0.41), although the relative risks decrease significantly at level 3 (RRR = 0.66; p = 0.03). When controlling for age, the relative risks between frailty levels 4 to 7 significantly decreased as cognitive performance increased (RRR = 0.46, RRR = 0.52, RRR = 0.44, RRR = 0.32; p < 0.001). Conclusion: Our results show an association between frailty levels measured in a novel way, and cognitive decline across different cultural settings.

RESUMEN

In this article, we summarise the findings of the situational analysis of dementia care generated as part of the STRiDE: Strengthening responses to dementia care in developing countries project, including a desk review, a SWOT analysis and views from relevant stakeholders. In addition, the article incorporates the experience of 4 years of work within the STRiDE project of FEDMA, Mexico's Federation of Alzheimer's and other dementias and its allied Associations in presenting specific recommendations to optimise dementia care in the country. All the information gathered brings together a detailed understanding of the current dementia care systems of diagnosis, treatment, and support in general and what is lacking, allowing for the generation of general recommendations to enhance the isolated efforts currently available and amplify their impact, as well as strategies to generate new services currently unavailable, but urgently needed.

RESUMEN

After the first wave of the COVID-19 pandemic, during which the severity of the disease in certain countries was attributed to a lack of basic education of the inhabitants, the authors of this paper initiated a literature review of educational trajectories, health, and ageing well. The findings strongly demonstrate that alongside genetics, the affective and educational family environment, as well as the general environment, greatly interact starting from the very first days of life. Thus, epigenetics plays a major role in the determination of health and disease [DOHAD] in the first 1,000 days of life as well as in the characterization of gender. Other factors such as socio-economic level, parental education, schooling in urban or rural areas, also play a major role in the differential acquisition of health literacy. This determines adherence (or lack thereof) to healthy lifestyles, risky behaviours, substance abuse, but also compliance with hygiene rules, and adherence to vaccines and treatments. The combination of all these elements and lifestyle choices facilitates the emergence of metabolic disorders (obesity, diabetes), which promote cardiovascular and kidney damage, and neurodegenerative diseases, explaining that the less well educated have shorter survival and spend more years of life in disability. After having demonstrated the impact of the educational level on health and longevity, the members of this inter-academic group propose specific educational actions at three levels: (1) teachers and health professionals, (2) parents, (3) the public, emphasizing that these crucial actions can only be carried out with the unfailing support of state and academic authorities.

RESUMEN

OBJECTIVES: Vaccination has been effective in ameliorating the impact of COVID-19. Here, we report vaccine effectiveness (VE) of the nationally available COVID-19 vaccines in Mexico. METHODS: Retrospective analysis of a COVID-19 surveillance system to assess the VE of the BNT162b2, messenger RNA (mRNA)-12732, Gam-COVID-Vac, Ad5-nCoV, Ad26.COV2.S, ChAdOx1, and CoronaVac vaccines against SARS-CoV-2 infection, COVID-19 hospitalization, and death in Mexico. The VE was estimated using time-varying Cox proportional hazard models in vaccinated and unvaccinated adults, adjusted for age, sex, and comorbidities. VE was also estimated for adults with diabetes, aged ≥60 years, and comparing the predominance of SARS-CoV-2 variants B.1.1.519 and B.1.617.2. RESULTS: We assessed 793,487 vaccinated and 4,792,338 unvaccinated adults between December 24, 2020 and September 27, 2021. The VE against SARS-CoV-2 infection was the highest for fully vaccinated individuals with mRNA-12732 (91.5%, 95% confidence interval [CI] 90.3-92.4) and Ad26.COV2.S (82.2%, 95% CI 81.4-82.9); for COVID-19 hospitalization, BNT162b2 (84.3%, 95% CI 83.6-84.9) and Gam-COVID-Vac (81.4% 95% CI 79.5-83.1), and for mortality, BNT162b2 (89.8%, 95% CI 89.2-90.2) and mRNA-12732 (93.5%, 95% CI 86.0-97.0). The VE decreased for all vaccines in adults aged ≥60 years, people with diabetes, and periods of Delta variant predominance. CONCLUSION: All the vaccines implemented in Mexico were effective against SARS-CoV-2 infection, COVID-19 hospitalization, and death. Mass vaccination with multiple vaccines is useful to maximize vaccination coverage.

RESUMEN

Aging is believed to occur across multiple domains, one of which is body composition; however, attempts to integrate it into biological age (BA) have been limited. Here, we consider the sex-dependent role of anthropometry for the prediction of 10-year all-cause mortality using data from 18,794 NHANES participants to generate and validate a new BA metric. Our data-driven approach pointed to sex-specific contributors for BA estimation: WHtR, arm and thigh circumferences for men; weight, WHtR, thigh circumference, subscapular and triceps skinfolds for women. We used these measurements to generate AnthropoAge, which predicted all-cause mortality (AUROC 0.876, 95%CI 0.864-0.887) and cause-specific mortality independently of ethnicity, sex, and comorbidities; AnthropoAge was a better predictor than PhenoAge for cerebrovascular, Alzheimer, and COPD mortality. A metric of age acceleration was also derived and used to assess sexual dimorphisms linked to accelerated aging, where women had an increase in overall body mass plus an important subcutaneous to visceral fat redistribution, and men displayed a marked decrease in fat and muscle mass. Finally, we showed that consideration of multiple BA metrics may identify unique aging trajectories with increased mortality (HR for multidomain acceleration 2.43, 95%CI 2.25-2.62) and comorbidity profiles. A simplified version of AnthropoAge (S-AnthropoAge) was generated using only BMI and WHtR, all results were preserved using this metric. In conclusion, AnthropoAge is a useful proxy of BA that captures cause-specific mortality and sex dimorphisms in body composition, and it could be used for future multidomain assessments of aging to better characterize the heterogeneity of this phenomenon.

RESUMEN

AIM: To evaluate the readiness of the Mexican healthcare system to implement the integrated care for older people (ICOPE) approach into an existing healthcare model. METHODS: We conducted a cross-sectional study with data from 2473 healthcare workers analyzed using the model for understanding success in quality (MUSIQ) framework to gather data from healthcare professionals. Their perceptions regarding the readiness for ICOPE were assessed across five dimensions: team, microsystem, infrastructure, organization, and external environment. RESULTS: Only 717 (29%) of the participants believed ICOPE could be successfully implemented in Mexico without any modifications. A total of 1261 (51%) participants rated the readiness of ICOPE with some barriers. The main barriers were reallocating resources and the external environment. OBSERVATION: Mexico's healthcare system faces barriers to innovation that could hinder the successful integration of the ICOPE approach. A systematic identification of these barriers provides an opportunity to suggest adaptations and refinements to increase the probability of success. Using the contextual factors identified as facilitators and the proposal of interventions such as the ICOPE app could improve the chances of success. CONCLUSION: The participants of this study evaluated ICOPE as ready to implement, with some contextual barriers. The readiness evaluation supports the stakeholders' and policymakers' decisions in implementing and monitoring the program in a natural setting. Evaluating the readiness of the intervention increases the possibility of aligning the innovation with contextual factors, increasing the chances of its successful adoption and implementation.

RESUMEN

BACKGROUND: In 2020, Mexico experienced one of the highest rates of excess mortality globally. However, the extent of non-COVID deaths on excess mortality, its regional distribution and the association between socio-demographic inequalities have not been characterized. METHODS: We conducted a retrospective municipal and individual-level study using 1 069 174 death certificates to analyse COVID-19 and non-COVID-19 deaths classified by ICD-10 codes. Excess mortality was estimated as the increase in cause-specific mortality in 2020 compared with the average of 2015-2019, disaggregated by primary cause of death, death setting (in-hospital and out-of-hospital) and geographical location. Correlates of individual and municipal non-COVID-19 mortality were assessed using mixed effects logistic regression and negative binomial regression models, respectively. RESULTS: We identified a 51% higher mortality rate (276.11 deaths per 100 000 inhabitants) compared with the 2015-2019 average period, largely attributable to COVID-19. Non-COVID-19 causes comprised one-fifth of excess deaths, with acute myocardial infarction and type 2 diabetes as the two leading non-COVID-19 causes of excess mortality. COVID-19 deaths occurred primarily in-hospital, whereas excess non-COVID-19 deaths occurred in out-of-hospital settings. Municipal-level predictors of non-COVID-19 excess mortality included levels of social security coverage, higher rates of COVID-19 hospitalization and social marginalization. At the individual level, lower educational attainment, blue-collar employment and lack of medical care assistance prior to death were associated with non-COVID-19 deaths. CONCLUSION: Non-COVID-19 causes of death, largely chronic cardiometabolic conditions, comprised up to one-fifth of excess deaths in Mexico during 2020. Non-COVID-19 excess deaths occurred disproportionately out-of-hospital and were associated with both individual- and municipal-level socio-demographic inequalities.

RESUMEN

Background: Research suggests a significant association between increasing age and memory impairments. Nevertheless, for some individuals, memory performance stays within or above the normative values of younger subjects. This is known as successful memory aging and is associated with specific neurophysiological features and psychological and lifestyle-related variables. To date, little is known about the association between successful memory aging and intrinsic capacity (IC) defined as "the composite of all the physical and mental (including psychosocial) capacities that an individual can draw on at any point in time" and resilience. Hence, the aim of this study was to determine if longitudinal associations between IC and successful memory aging and resilience exist and to find differences in cognitive performance between Mexican older adults with successful memory aging, older adults with average memory, and older adults with memory impairment. Methods: Longitudinal data from 590 individuals from the third wave (2012) and the Mex-Cog subsample (2016) of the Mexican Health and Aging Study was analysed. Subjects were classified into 3 groups: (1) older adults with successful memory aging (SUMA), (2) older adults with average memory (AVMA), and (3) older adults with memory impairment (IMA). Cognitive domains of orientation, language, attention, constructional praxis, and executive function were evaluated. IC and resilience were measured using items from the MHAS battery. Analysis of variance and multinomial logistic regressions were used to find differences in IC and resilience across the memory aging groups. Results: ANOVAs showed significant differences across the three cognitive performance groups in all cognitive domains. Multinomial logistic regression analyses revealed that respondents with higher scores in the psychological and cognitive domains of IC at baseline were more likely to have successful memory aging in the subsequent wave of the study. More resilient subjects in 2012 were not more likely to become a SUMA in 2016. However, this could be a result of the way resilience was measured. Conclusion: Our main findings suggest that intrinsic capacity could be used as a predictor of successful memory aging specifically in the psychological and the cognitive domains. More longitudinal studies are needed to further examine these associations.

RESUMEN

INTRODUCTION: Midlife physical capability (PC) is associated with developmental factors in the populations of economically developed countries. As far as we know, there is no information for rural populations of low- and middle-income countries. The aim of the study was to investigate the influence of pre- and postnatal factors on midlife objective measures of PC in a 1966-67 birth cohort from a Mexican rural community. The hypothesis was that adverse developmental conditions are associated with low midlife PC. METHODS: In 1966-67, a birth cohort of all children from a poor Mexican rural community was assembled. Data on family socioeconomic status (SES), parental health and nutritional status, birth weight, postnatal growth and feeding patterns were registered. In 2018, out of the 336 cohort members, 118 were living in the community, and eighty-two of them underwent a comprehensive clinical evaluation. The evaluation included grip strength, gait velocity and chair-stand PC tests. In multivariable linear models, PC tests were the dependent variables, and prenatal, birth and postnatal factors were the independent variables. Adjustment for confounding was made with adult anthropometric, body composition, clinical and ageing status variables. RESULTS: Independent of adult health status and other ageing indicators, lower PC was associated with family organization and SES, parental nutritional status, birth weight, infant postnatal growth velocity, and weaning time. These results indicate that adverse family and environmental conditions that are prevalent in poor rural communities are associated with low midlife PC.

RESUMEN

OBJECTIVES: To evaluate the feasibility outcomes of implementing a multicomponent staff training intervention (PROCUIDA-Demencia) to promote psychosocial interventions and reduce antipsychotic prescription in Mexican care homes and study its effect on staff's care experience and residents' quality of life. DESIGN: A mixed-methods 2-arm cluster randomized controlled pilot study of a 2-day staff training program with baseline, 12 weeks, and 24 weeks of the PROCUIDA-Demencia intervention vs treatment as usual (TAU). SETTING AND PARTICIPANTS: Eight care homes in Mexico City were selected, from which 55 residents and 126 staff were recruited. INTERVENTION: In situ staff training consisting of evidence-based manualized psychosocial interventions of person-centered activities, reminiscence therapy, doll therapy, psychomotor dance therapy, and antipsychotic prescription review. Fidelity to protocol was supervised once a week. METHODS: Cluster-level feasibility measures included views of staff, residents, and relatives on acceptability, satisfaction, adherence, and fidelity to the intervention. Staff outcome measures were Maslach Burnout Inventory (MBI), Approaches to Dementia Questionnaire, and Sense of Competence in Dementia Care Staff. Residents' outcome measures included Quality of Life-Alzheimer's Disease scale (QoL-AD), and Neuropsychiatric Inventory-Nursing Home Version (NPI-NH). Staff distress was measured using the NPI-NH occupational disturbance scale. Feasibility was elicited through a focus group, and hierarchical linear mixed effects models were used to assess the adjusted effects of the respective measures. RESULTS: Observed medical practice showed the prescription of at least 1 antipsychotic in 41% of participants in the intervention group. Overall, 39% of residents reported discontinuation, and 15% reduction of antipsychotics, following the 12-week medical review in parallel with psychosocial interventions. Clinical outcomes contributed positively to the reduction in baseline staff burden according to the MBI after the intervention [mean difference -8.9, 95% confidence interval (CI) -17.7, -0.1, P = .049] and to the reduction in severity and frequency of behavior as per NPI-NH in residents (mean difference -9.4, 95% CI -17.5, -1.3, P = .025). CONCLUSIONS AND IMPLICATIONS: PROCUIDA-Demencia is a feasible intervention for Mexican care homes. Results contribute to the Mexican Dementia Plan optimizing dementia care by supporting the need for staff training to implement psychosocial interventions prior to prescribing antipsychotic medication.

RESUMEN

BACKGROUND: The impact of the coronavirus disease 2019 (COVID-19) pandemic in Mexico City has been sharp, as several social inequalities at all levels coexist. Here we conducted an in-depth evaluation of the impact of individual and municipal-level social inequalities on the COVID-19 pandemic in Mexico City. METHODS: We analyzed suspected severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cases, from the Mexico City Epidemiological Surveillance System from 24 February 2020 to 31 March 2021. COVID-19 outcomes included rates of hospitalization, severe COVID-19, invasive mechanical ventilation, and mortality. We evaluated socioeconomic occupation as an individual risk, and social lag, which captures municipal-level social vulnerability, and urban population density as proxies of structural risk factors. Impact of reductions in vehicular mobility on COVID-19 rates and the influence of risk factors were also assessed. Finally, we assessed discrepancies in COVID-19 and non-COVID-19 excess mortality using death certificates from the general civil registry. RESULTS: We detected vulnerable groups who belonged to economically unfavored sectors and experienced increased risk of COVID-19 outcomes. Cases living in marginalized municipalities with high population density experienced greater risk for COVID-19 outcomes. Additionally, policies to reduce vehicular mobility had differential impacts modified by social lag and urban population density. Finally, we report an under-registry of COVID-19 deaths along with an excess mortality closely related to marginalized and densely populated communities in an ambulatory setting. This could be attributable to a negative impact of modified hospital admission criteria during the pandemic. CONCLUSIONS: Socioeconomic occupation and municipality-wide factors played a significant role in shaping the course of the COVID-19 pandemic in Mexico City.

RESUMEN

In this article, we report on the recommendations of a binational conference that examined the institutional capacities and future ability of Mexico and the United States to address the need for affordable and sustainable dementia care that results from growing older adult populations. These recommendations reflect the large difference in resources between the two nations and each country's political and institutional capacity. Progress in both countries will require an expansion of programs or the generation of new ones, to meet the needs of older adults, including improving access to services and actively managing the dementia care burden. A comprehensive federal health care safety net will be required in both nations, but economic realities will constrain its implementation. Both nations suffer from a persistent shortage of geriatric primary care physicians and geriatricians, especially in rural areas. Advances in diagnosis, treatment, and care management require additional knowledge and skills of general and specialized staff in the health care workforce to deliver evidence-based, culturally and linguistically appropriate long-term care, and human rights-oriented services. We conclude with a discussion of recommendations for binational dementia care policy and practice.
