ABSTRACT

OBJECTIVE: It is estimated that 2% of dementia cases worldwide could be prevented with increases in physical activity. However, there is little evidence of the association between vigorous physical activity (VPA) and cognitive performance. This study aimed to investigate the association of moderate physical activity (MPA) and VPA with cognitive performance in older adults from the Brazilian Longitudinal Study of Aging (ELSI-Brasil). PATIENTS AND METHODS: Data from 7954 participants were analyzed. Mean age was 61.8 ± 9.2 years, 61.8% were women, and 44.3% were mixed races. Cognitive performance evaluated the memory, temporal orientation, and verbal fluency domains. A global composite z-score was derived from the tests. Physical activity was assessed by self-report. We used linear regression models to verify the association of MPA and VPA with cognitive performance. RESULTS: Compared with participants who did not meet the guidelines for MPA (<150 min/wk), those who met the guidelines (150 to 299 min/wk) and those who performed more than 2x the recommended amount of MPA (300 min or more/wk) had better global cognitive performance (ß = 0.163, 95% CI = 0.086, 0.241; P < 0.001; ß = 0.180, 95% CI = 0.107, 0.253, P < 0.001, respectively). We found no association between VPA and cognitive performance. CONCLUSION: There was no additional benefit of VPA for cognitive performance.

ABSTRACT

BACKGROUND: Depression in ageing adults is a public health problem. Worldwide studies have identified social and health risk factors for depressive symptoms. However, little is known about their longitudinal determinants in Mexico. OBJECTIVES AND SETTING: To find the prevalence of depressive symptoms and their longitudinal individual and contextual risk factors in Mexican adults aged 50 and older. DESIGN: Secondary data of 6460 persons aged 50 years and older from the Mexican Health and Aging Study were analysed using a 'between-within' panel data analysis approach. RESULTS: The prevalence of depressive symptoms increased from 35% in 2003 to 38% in 2015. The significantly longitudinal factors associated with these symptoms were getting older (OR 1.02, 95% CI 1.01 to 1.03), being a woman (OR 2.39, 95% CI 2.16 to 2.64), less time spent in formal education (0 years and less than 6 years OR 1.52, 95% CI 1.32 to 1.75 and OR 1.33, 95% CI 1.19 to 1.50, respectively), lower net worth (OR 1.13, 95% CI 1.08 to 1.17), being recently unemployed (OR 1.25, 95% CI 1.10 to 1.25), increased (OR 1.17, 95% CI 1.10 to 1.25) or increasing number (OR 1.23, 95% CI 1.15 to 1.31) of chronic conditions, poor (OR 4.68, 95% CI 4.26 to 5.15) or worsened (OR 1.71, 95% CI 1.61 to 1.81) self-rated health and having impairments on instrumental activities of daily living (IADLs) (OR 2.94 95% CI 2.35 to 3.67) or a new IADL impairment (OR 1.67, 95% CI 1.48 to 1.89), as well as having impairments on ADLs (OR 1.51, 95% CI 1.23 to 1.86) or a new ADL impairment (OR 1.34, 95% CI 1.21 to 1.48). CONCLUSIONS: The prevalence of depressive symptoms in Mexican adults aged 50 and older is high. Our findings show that they are longitudinally associated with the individual's demographic, socioeconomic, health and disability characteristics. Efforts in public policy should focus on preventing chronic conditions and disability, as well as fighting inequalities to reduce the prevalence of depressive symptoms.

ABSTRACT

BACKGROUND: Functional capacity is recognized as a central factor for health in old age and not all studies that seek to clarify the role of social relationships in functional capacity are conclusive. The subject has only been studied in a limited way in Latin America, a region that is aging prematurely, with evidence primarily from developed countries, which have experienced a more gradual aging of their population. This longitudinal study aimed to determine how aspects of social relationships impact the functionality of older Chileans. METHODOLOGY: We conducted a cohort study of 2,265 people aged 60 years or older who lived in the community and resided in Greater Santiago, Chile. Five aspects of social relationships were considered at baseline (participation in groups, clubs, or organizations; number of people in the household; participation in recreational activities; perception of material support, help or advice, and marital status), from which a cluster analysis by conglomerate was performed and used as the exposure of interest. Functional limitation (FL) was the dependent variable, classified as a limitation in at least 1 basic activity of daily living or 1 instrumental activity or 2 advanced activities. The control variables considered were: sex, age, educational level, multimorbidity, depression and years of follow-up. Survival analyses using a Cox proportional hazard regression and multilevel logistic regressions (person level and follow-up wave level) were performed. RESULTS: The identified clusters were four: "without social participation and does not live alone"; "without a partner and without social participation"; "no perception of support and no social participation"; "with participation, partner and perception of support". Social relationship clusters predicted FL incidence and FL reporting during follow-up. Being in the clusters "without social participation and does not live alone" and "without partner and without social participation" were risk factors for incident FL and report of FL during follow-up, compared to being in the reference cluster "with participation, partner and perception of support. CONCLUSIONS: In summary, our study showed that participating in social organizations, not living alone and having a partner are protective factors for presenting and developing functional limitation in old age for community-living Chileans in an urban area.

ABSTRACT

BACKGROUND: Given the importance of understanding psychosocial well-being as part of aging characteristics and processes, the present study aimed to describe life satisfaction among middle-aged and older adults in Mexico, according to sociodemographic, economic, psychosocial, and health factors. METHODS: Data were obtained from the Mexican Health and Aging Study (MHAS), a longitudinal, nationally representative survey of adults aged 50 years and older. Data from the 2012, 2015, and 2018 waves were analyzed for this study. Life satisfaction in the MHAS is assessed using the Spanish version of the Satisfaction with Life Scale (SWLS). For the construction of the trajectories over six years of follow-up, quartiles of the scale were calculated for each wave. Multinomial regression models were then estimated to determine significant factors associated with each trajectory. RESULTS: A total of 8,376 individuals aged 50 years and older met our study criteria for complete data in the three follow-up waves. Four life satisfaction trajectories were identified over six years of follow-up: high-constant, high-low, low-high, and low-constant. Subjective or psychosocial characteristics such as depressive symptoms, self-reported health, and functional ability were highly significant factors associated with life satisfaction trajectories, while multimorbidity was not significant. CONCLUSIONS: This research contributes to the understanding of psychosocial well-being in Mexican older adults by exploring life satisfaction trajectories and their associated factors. The study shows that psychosocial and economic factors, along with functional abilities, have a much greater impact on life satisfaction, beyond the presence of comorbidity.

ABSTRACT

OBJECTIVES: The Latino population is one of the largest, most diverse, and fastest-growing demographic groups in the United States. Although Latinos enjoy longer life spans and reduced mortality risk relative to non-Hispanic Whites, they have higher rates of chronic health conditions such as diabetes and dementia and live more of their older years with poor health and disability. Such inequities point to the need for this research focused on examining resiliency strategies and barriers to successful aging among various U.S. Latino subgroups. METHODS: This qualitative study used thematic content analysis to examine resiliency strategies and barriers to successful aging among Mexican immigrant women (n = 40) residing in an underserved agricultural community and entering mid-life (mean = 49 years old). RESULTS: With regards to barriers to successful aging, 3 themes emerged: (1) stressful lifestyle in the United States compared to the participants' home countries; (2) stress from expectations at home; and (3) stress due to work and the various components around work. The following 4 resiliency strategies emerged: (1) family as a motivation for moving forward in life and focusing on the success of children; (2) having a positive mindset; (3) praying to God for strength to overcome obstacles; and (4) self-care. DISCUSSION: Despite experiencing barriers to successful aging, participants practice various resiliency strategies to age successfully. Because many of the barriers identified are related to poverty-related stressors, systemic solutions addressing the social determinants of health are needed.

ABSTRACT

Dementia is a syndrome characterized by cognitive and neuropsychiatric symptoms associated with progressive functional decline (FD). FD is a core diagnostic criterion for dementia, setting the threshold between its prodromal stages and the full-blown disease. The operationalization of FD continues to generate a great deal of controversy. For instance, the threshold of FD for the diagnosis of dementia varies across diagnostic criteria, supporting the need for standardization of this construct. Moreover, there is a need to reconsider how we are measuring FD to set boundaries between normal aging, mild cognitive impairment, and dementia. In this paper, we propose a multidimensional framework that addresses outstanding issues in the assessment of FD: i) What activities of daily living (ADLs) are necessary to sustain an independent living in aging? ii) How to assess FD in individuals with suspected neurocognitive disorders? iii) To whom is the assessment directed? and iv) How much does FD differentiate healthy aging from mild and major neurocognitive disorders? Importantly, the To Whom Question introduces a person-centered approach that regards patients and caregivers as active agents in the assessment process of FD. Thus, once impaired ADLs have been identified, patients can indicate how significant such impairments are for them in daily life. We envisage that this new framework will guide future strategies to enhance functional assessment and treatment of patients with dementia and their caregivers.

ABSTRACT

Aging involves physical and cognitive deterioration in older adults. Detecting predictors of dementia early is crucial to identify its onset. This study aimed to associate physical and psychological determinants with cognitive performance in older adults. Observational study with 221 older adults, classified according to cognitive impairment. We evaluated cognitive function by Mini-Mental State Examination. Physical determinants encompassed muscle strength, functional mobility, and cardiorespiratory fitness, while psychological consisted of quality of life and activities of daily living. Multiple linear regression was performed to investigate this relationship. Physical and psychological determinants were significantly linked to cognitive impairment, including lower muscle strength, reduced functional mobility and of cardiorespiratory fitness. The influence of environment, autonomy, and engagement in daily activities on cognitive impairment was also observed. The analysis of physical and psychological determinants could help to aid in distinguishing individuals with cognitive impairment.

ABSTRACT

INTRODUCTION: Neighborhood socioeconomic status (NSES) has been linked with overall health, and this study will evaluate whether NSES is cross-sectionally associated with cognition in non-Hispanic whites (NHWs) and Mexican Americans (MAs) from the Health and Aging Brain: Health Disparities Study (HABS-HD). METHODS: The HABS-HD is a longitudinal study conducted at the University of North Texas Health Science Center. The final sample analyzed (n = 1,312) were 50 years or older, with unimpaired cognition, and underwent an interview, neuropsychological examination, imaging, and blood draw. NSES was measured using the national area deprivation index (ADI) percentile ranking, which considered socioeconomic variables. Executive function and processing speed were assessed by the trail making tests (A and B) and the digit-symbol substitution test, respectively. Linear regression was used to assess the association of ADI and cognitive measures. RESULTS: MAs were younger, more likely to be female, less educated, had higher ADI scores, performed worse on trails B (all p < 0.05), and had lower prevalence of APOE4 + when compared to NHWs (p < 0.0001). A higher percentage of MAs lived in the most deprived neighborhoods than NHWs. For NHWs, ADI did not predict trails B or DSS scores, after adjusting for demographic variables and APOE4. For MAs, ADI predicted trails A, trails B, and DSS after adjusting for demographic covariates and APOE4 status. CONCLUSION: Our study revealed that living in an area of higher deprivation was associated with lower cognitive function in MAs but not in NHWs, which is important to consider in future interventions to slow cognitive decline.

ABSTRACT

OBJECTIVES: Depression is a prevalent mental health condition that also often affects older adults. The PROACTIVE psychosocial intervention was developed to reduce depressive symptomatology among older adults within primary care settings in Brazil. An important psychological marker that affects individuals' aging experience relates to how old people feel. Known as subjective age, this marker has been shown to be a risk factor for experiencing greater depressive symptoms if individuals report feeling older than their (chronological) age. In this study, we perform secondary analyses of the PROACTIVE cluster-randomized controlled trial to examine the role of subjective age. METHOD: The sample included 715 Brazilian older adults (74% female, Mage 68.6, SD = 6.9, age range: 60-94 years) randomized to intervention (n = 360, 74% female, Mage 68.4, SD = 6.6, age range: 60-89 years) or control (n = 355, 74% female, Mage 68.9, SD = 7.2, age range: 60-94 years) arms. Here our primary outcome was depressive symptoms at the 8-month follow-up assessed with the 9-item Patient Health Questionnaire (PHQ-9) as a continuous variable. Our previous analyses demonstrated improved recovery from depression at follow-up in the intervention compared with the control arm. RESULTS: Relevant main effects and interactions in regression models for PHQ-9 presented here found that those reporting older subjective age had worse depressive symptoms at follow-up but that they benefitted more from the intervention when initial levels of depression were high. For participants who reported younger subjective ages the intervention showed positive effects that were independent of initial levels of depression. CONCLUSION: Our findings emphasize the importance of investigating possible underlying mechanisms that can help clarify the impact of mental health interventions.

ABSTRACT

OBJECTIVE: The aim of this study was to determine the state of aging anxiety in middle-aged women. METHODS: The study was collected from women between the ages of 40 and 59 years by an online survey method. While collecting the data of the participants, the women's personal characteristics diagnostic form and the Aging Anxiety Scale for Middle-Aged Women were used. The data were analyzed with the SPSS 26 statistical software. RESULTS: The aging anxiety of the women was found to be moderate (53.05±16.26). A significant correlation was found between women's menopausal status, household income, education level, and total score of aging anxiety (p<0.05). CONCLUSION: In addition to working outside the home, women are also burdened with duties inside the home. To improve their quality of life, women need to share many of the tasks imposed on them with other family members. To reduce the anxiety experienced by women during the climacteric period, it is recommended to provide psychosocial support to women and consider this issue in health policies. Healthcare professionals, especially nurses, have important duties to reduce anxiety and stress, which constitute the basis of many chronic diseases. It is recommended that nurses, who are health ambassadors, direct women with anxiety to psychological support services through screenings they will conduct for women during this period.

ABSTRACT

OBJECTIVE: Most prior research on physical activity (PA) and cognition is based on predominantly white cohorts and focused on associations of PA with mean (average) cognition versus the distribution of cognition. Quantile regression offers a novel way to quantify how PA affects cognition across the entire distribution. METHODS: The Kaiser Healthy Aging and Diverse Life Experiences study includes 30% white, 19% black, 25% Asian, and 26% Latinx adults age 65+ living in Northern California (n = 1600). The frequency of light or heavy PA was summarized as 2 continuous variables. Outcomes were z-scored executive function, semantic memory, and verbal episodic memory. We tested associations of PA with mean cognition using linear regression and used quantile regression to estimate the association of PA with the 10th-90th percentiles of cognitive scores. RESULTS: Higher levels of PA were associated with higher mean semantic memory (b = 0.10; 95% CI: 0.06, 0.14) and executive function (b = 0.05; 95% CI: 0.01, 0.09). Associations of PA across all 3 cognitive domains were stronger at low quantiles of cognition. CONCLUSION: PA is associated with cognition in this racially/ethnically diverse sample and may have larger benefits for individuals with low cognitive scores, who are most vulnerable to dementia.

ABSTRACT

BACKGROUND: With aging, some cognitive abilities change because of neurobiological processes. Cognition may also be influenced by psychosocial aspects. OBJECTIVE: To describe the relationship between a measure of neuroticism, depression symptoms, purpose in life, and cognitive performance in community-dwelling older adults. METHODS: This was a cross-sectional analysis based on the data from the second wave of the Frailty in Brazilian Older Adults (FIBRA) study, carried out between 2016 and 2017. The sample consisted of 419 older people (≥ 72 years old) cognitively unimpaired and mostly with low education. The variables of interest were sociodemographic, Neuroticism domain from the NEO-PI-R, Geriatric Depression Scale (GDS), Purpose in Life (PiL) scale, and a cognitive composite score which included the Mini-Mental State Examination (MMSE), and the scores for the sub-items of the Mini-Addenbrooke's Cognitive Examination (M-ACE), namely, Verbal Fluency (VF) - Animal, Clock Drawing Test (CDT), Episodic Memory (name and address). RESULTS: There was a greater number of women (70%), with older age (median = 80 years, IQR = 77-82), and low education (median = 4 years, IQR = 2-5). In the bivariate correlations, years of education (ρ = 0.415; p < 0.001) and PiL (ρ = 0.220; p < 0.001) were positively associated with cognition. Neuroticism (ρ = -0.175; p < 0.001) and depression symptoms (ρ = -0.185; p < 0.001) were negatively associated with cognition. In the logistic regression, after including confounding variables, the associations between cognition and PiL (OR = 2.04; p = 0.007) and education (OR = 1.32; p < 0.001) remained significant. CONCLUSION: Low PiL and low education levels were associated with worse cognition among older adults. Such results may be of relevance in programs that aim to improve cognition among older adults.


ANTECEDENTES: Com o envelhecimento, algumas habilidades cognitivas mudam devido a processos neurobiológicos. A cognição também pode ser influenciada por aspectos psicossociais. OBJETIVO: Descrever as relações entre uma medida de neuroticismo, sintomas depressivos, propósito de vida e o desempenho cognitivo em pessoas idosas residentes na comunidade. MéTODOS: Trata-se de uma análise transversal com base nos dados da segunda onda do estudo de Fragilidade em Idosos Brasileiros (FIBRA), realizado entre 2016 e 2017. A amostra foi composta por 419 pessoas idosas (≥ 72 anos) cognitivamente saudáveis e em maior parte com baixa escolaridade. As variáveis de interesse foram as sociodemográficas, domínio Neuroticismo do NEO-PI-R, Escala de Depressão Geriátrica (EDG) e Escala de Propósito de Vida (PV) e um escore cognitivo composto que incluiu o Miniexame de Estado Mental (MEEM) e as pontuações dos subitens do Miniexame Cognitivo de Addenbrooke (M-ACE), a saber, Fluência Verbal (FV) Animal, Teste do Desenho do Relógio (TDR) e Memória Episódica (nome e endereço). RESULTADOS: Houve um maior número de mulheres (70%), com idade elevada (mediana = 80 anos, IIQ = 77-82) e baixa escolaridade (mediana = 4 anos, IIQ = 2-5). Nas correlações bivariadas, anos de escolaridade (ρ = 0,415; p < 0,001) e PV (ρ = 0,220; p < 0,001) foram positivamente associadas à cognição. Neuroticismo (ρ = -0,175; p < 0,001) e sintomas depressivos (ρ = -0,185; p < 0,001) foram negativamente associados à cognição. Na regressão logística, após a inclusão de variáveis de confusão, as associações entre cognição e PV (OR = 2,04; p = 0,007) e escolaridade (OR = 1,32; p < 0,001) permaneceram significativas. CONCLUSãO: Baixo PV e baixa escolaridade foram associados à pior cognição em idosos. Tais resultados podem ser relevantes em programas que visam a melhorar a cognição entre pessoas idosas.

ABSTRACT

An observational cross-sectional study was conducted to examine multidimensional frailty and its potential impact on quality of life (QOL) in aging Hispanic people living with HIV (PLWH) and assess the extent to which HIV self-management moderates this association. The sample included 120 Hispanic PLWH aged 50 years and older (M = 59.11; SD = 7.04). The structural equation modeling analyses demonstrated that multidimensional frailty was significantly related to QOL in its two dimensions, physical and mental (p < .001). The relationship between multidimensional frailty and mental and physical QOL remained significant even after controlling for confounders (age and gender). The moderator analyses indicated no statistically significant moderator effect of HIV self-management on multidimensional frailty and mental or physical QOL. These study results have practical implications that highlight the need for early screening for frailty with a multidimensional focus. Age-appropriate and culturally tailored interventions to prevent or mitigate multidimensional frailty may improve QOL.

ABSTRACT

INTRODUCTION: We conducted a cross-national comparison of the association between main lifetime occupational skills and later-life cognitive function across four economically and socially distinct countries. METHODS: Data were from population-based studies of aging and their Harmonized Cognitive Assessment Protocols (HCAPs) in the US, South Africa, India, and Mexico (N = 10,037; Age range: 50 to 105 years; 2016 to 2020). Main lifetime occupational skill was classified according to the International Standard Classification of Occupations. Weighted, adjusted regression models estimated pooled and country-specific associations between main lifetime occupational skill and later-life general cognitive function in men and women. RESULTS: We observed positive gradients between occupational skill and later-life cognitive function for men and women in the US and Mexico, a positive gradient for women but not men in India, and no association for men or women in South Africa. DISCUSSION: Main lifetime occupations may be a source of later-life cognitive reserve, with cross-national heterogeneity in this association. HIGHLIGHTS: No studies have examined cross-national differences in the association of occupational skill with cognition. We used data from Harmonized Cognitive Assessment Protocols in the US, Mexico, India, and South Africa. The association of occupational skill with cognitive function varies by country and gender.

ABSTRACT

BACKGROUND: Increased interindividual variability in cognitive performance during aging has been proposed as an indicator of cognitive reserve. OBJECTIVE: To determine if interindividual variability performance in episodic memory (PAL), working memory (SWM), reaction time (RTI), and sustained attention (RVP) could differentiate clusters of differential cognitive performance in healthy young and older adults and search for cognitive tests that most contribute to these differential performances. METHODS: We employed hierarchical cluster and canonical discriminant function analyses of cognitive scores using the Cambridge Neuropsychological Test Automated Battery (CANTAB) to identify cognitive variability in older and young adults using the coefficient of variability of cognitive performances between and within groups. We also analyzed potential influences of age, education, and physical activity. RESULTS: Cluster analysis distinguished groups with differential cognitive performance and correlation analysis revealed coefficient of variability and cognitive performance associations. The greater the coefficient of variability the poorer was cognitive performance in RTI but not in PAL and SWM. Older adults showed diverse trajectories of cognitive decline, and better education or higher percentage of physically active individuals exhibited better cognitive performance in both older and young adults. CONCLUSION: PAL and SWM are the most sensitive tests to investigate the wide age range encompassing older and young adults. In older adults' intragroup analysis PAL showed greater discriminatory capacity, indicating its potential for clinical applications late in life. Our data underscore the importance of studying variability as a tool for early detection of subtle cognitive declines and for interpreting results that deviate from normality.

ABSTRACT

RESUMO Este estudo teve como objetivo avaliar a intervenção psicológica positiva para promoção de saúde de aposentados, a partir da avaliação dos participantes, no que se refere à satisfação com o programa e com o moderador, clareza/compreensão/aplicação dos conteúdos e manutenção da aplicação ao longo de tempo, com delineamento longitudinal misto e avaliação pré (T1), pós-teste (T2) e seguimento (T3 - 03 meses). Participaram 65 aposentados que responderam ao questionário misto de avaliação do programa. Análises quantitativas indicaram maiores médias para satisfação com o programa e com o moderador; e menor média para tempo de duração do programa. 77,7% participantes em T2 e 87,2% em T3 utilizaram nas suas vidas os conteúdos trabalhados no programa.

ABSTRACT This study aimed to evaluate a Positive Psychology programme for health promotion of retirees, based on evaluation of participants with regard to levels of satisfaction with the programme/group and with the moderator, comprehension and application of contents and maintenance/long-term application of contents. A mixed longitudinal design, with pre-test (T1), post-test (T2), and follow-up (T3 - three months) evaluations was used. 65 retirees answered a programme evaluation questionnaire. Quantitative results indicated higher mean rates for satisfaction with the moderator and programme; and lower rates for the programme length/duration. Qualitative analysis indicated that 77.7% of the sample at T2, and 87.2% at T3 reported having used contents of the programme in their lives. Maintenance of application of contents was observed for empathy, self-care, optimism, gratitude, forgiveness and self-forgiveness. Positive outcomes demonstrate this pattern of intervention for health promotion - based on Positive Psychology and CBT - presents the potential to be applied within public health contexts for the promotion of active aging.

ABSTRACT

Estimates using data from the Mexican Health and Aging Study, a national longitudinal sample of older adults in Mexico, show elevated risk for negative mental health outcomes for those experiencing COVID-19 infection or major COVID-19-related adverse events. Predicted elevated probabilities were greater for a major adverse event than for COVID-19 infection, and they varied across sociodemographic groups defined by age, sex, education, and urban-rural residence.

ABSTRACT

Introduction: The productivity of individuals is assumed to decline upon reaching old age when cognitive ability is considered. This assumption is false, especially if the human development characteristics of people are analyzed, which highlights the need to recognize the heterogeneity among subpopulations. Methods: Using Wave two of the Brazilian Longitudinal Study on Aging, conducted from 2019 to 2021, this study explored the onset and speed of cognitive aging among older individuals aged at least 60 in Brazil, with reference to their education and income levels. Results: It was observed that although higher human capital characteristics yielded results toward later cognitive decline, women benefited more from having higher educational attainment levels. Such a pattern was similar among men and increased income levels. Disparities in cognitive performance, whether from education or income, were greatest at age 60, and this advantage diminished as age progressed. Conclusion: Viewing the older population as homogeneous in terms of health function is restrictive. It should be recognized that variations in social status affect individuals' health status into old age and therefore their respective potential for productivity should be maximized.

ABSTRACT

This study aimed to investigate differences in determinants of active aging between older Brazilian and English adults and to verify the association of behavioral, personal, and social determinants with physical health. This cross-sectional study was based on the ELSI-Brazil (2015-2016) and ELSA (2016-2017) cohorts. Active aging determinants included behavior (smoking, sedentary lifestyle, and poor sleep quality), personal (cognitive function and life satisfaction), and social determinants (education, loneliness, and volunteering), according to the World Health Organization. Physical health included activities limitation and multimorbidity. We estimated age- and sex-adjusted prevalence for each indicator and mean score, and used the negative binomial regression for statistical analysis. We included 16,642 participants, 9,409 from Brazil and 7,233 from England. Overall, all active aging determinants were worse in Brazil than in England, except for life satisfaction (no difference). The most remarkable difference was found for social determinants score in Brazil (mean difference of 0.18; p < 0.05), mainly due to a significantly lower education level in Brazil (70.6%; 95% confidence interval - 95%CI: 69.7-71.5) than England (37.1%; 95%CI: 35.1-39.1). All determinants (behavioral, personal, and social) were associated with health in Brazil and in England. However, the behavioral domain was stronger associated with health in England (coefficient = 2.76; 95%CI: 2.46-3.10) than in Brazil (coefficient = 1.38; 95%CI: 1.26-1.50; p < 0.001). Older English adults beneficiate more from healthier behaviors than Brazilians, which depend more on social policies.

ABSTRACT

BACKGROUND: Household wealth is positively related to cognitive health outcomes in later life. However, the association between negative wealth shocks and cognitive function in later life, and whether this association might differ across countries at different levels of economic development, is unclear. We aimed to investigate whether negative wealth shocks in later life are associated with cognitive function in older adults in China, England, Mexico, and the USA, and whether this association is modified by country income level. METHODS: For this population-based, cross-nationally harmonised, longitudinal study, data were analysed from core interviews of the population-based US Health and Retirement Study (2012 and 2016) and its partner studies in China (the China Health and Retirement Longitudinal Study; 2015 and 2018), England (the English Longitudinal Study of Ageing; 2012 and 2016), and Mexico (Mexican Health and Aging Study; 2012 and 2015-16), and their respective Harmonized Cognitive Assessment Protocols (HCAPs). Negative wealth shocks over the follow-up periods of the respective cohorts were defined in two ways: an extreme loss of 75% or greater from the baseline amount of wealth, and a decline in within-population wealth quintile rank. The primary outcome was the harmonised general cognitive function (GCF) factor score, which was constructed with factor analysis on the HCAP neuropsychological assessments of memory, orientation, attention, executive function, and verbal fluency performance (mean 0; SD 1). We used sampling-weighted, multivariable-adjusted linear models to examine associations. FINDINGS: Data from 9465 participants were included in this analysis: 3796 from China, 1184 from England, 1193 from Mexico, and 3292 from the USA. The mean baseline age of participants was 68·5 (SD 5·4) years in China (49·8% women), 72·0 (7·0) years in England (54·6% women), 70·6 (6·8) years in Mexico (55·1% women), and 72·7 (7·5) years in the USA (60·4% women). A wealth loss of 75% or greater was negatively associated with subsequent cognitive function in the USA (ß -0·16 SD units; 95% CI -0·29 to -0·04) and China (-0·14; -0·21 to -0·07), but not in England (-0·01; -0·24 to 0·22) or Mexico (-0·11; -0·24 to 0·03). Similarly, within-population wealth quintile rank declines were negatively associated with subsequent cognitive function in the USA (ß -0·07 per quintile rank decline; 95% CI -0·11 to -0·03) and China (ß -0·07; -0·09 to -0·04), but not in England (-0·05; -0·11 to 0·01) or Mexico (-0·03; -0·07 to 0·01). INTERPRETATION: The impact of wealth shocks in later life on subsequent lower level of cognitive function of older adults in China, England, Mexico, and the USA differed across macro-level socioeconomic structures. These findings suggest that government policies and social safety nets in countries with different levels of economic development might have a role in protecting older adults from adverse health effects of wealth losses in later life.
