Which model of successful ageing should be used? Baseline findings from a British longitudinal survey of ageing

Predicting successful ageing among older adults seems possible even as far as two decades ahead

BACKGROUND

Successful ageing is the term often used for depicting exceptional ageing and can be measured with multidimensional models including physical, psychological and social wellbeing. The aim of this study was to test multidimensional successful ageing models to investigate whether these models can predict successful ageing, and which individual subcomponents included in the models are most significantly associated with successful ageing.

METHODS

Successful ageing was defined as the ability to live at home without daily care at the age of 84 years or over. Data on the participants' physical, psychological and social wellbeing were gathered at baseline and the follow-up period was 20 years. Four successful ageing models were constructed. Backward stepwise logistic regression analysis was used to identify the individual subcomponents of the models which best predicted successful ageing.

RESULTS

All successful ageing models were able to predict ageing successfully after the 20-year follow-up period. After the backward stepwise logistic regression analysis, three individual subcomponents of four models remained statistically significant and were included in the new model: having no heart disease, having good self-rated health and feeling useful. As a model, using only these three subcomponents, the association with successful ageing was similar to using the full models.

CONCLUSIONS

Multidimensional successful ageing models were able to predict successful ageing after a 20-year follow-up period. However, according to the backward stepwise logistic regression analysis, the three subcomponents (absence of heart disease, good self-rated health and feeling useful) significantly associated with successful ageing performed as well as the multidimensional successful ageing models in predicting ageing successfully.

Beyond MACE: a multidimensional approach to outcomes in clinical trials for older adults with stable ischemic heart disease

The global population of older adults is expanding rapidly resulting in a shift towards managing multiple chronic diseases that coexist and may be exacerbated by cardiovascular illness. Stable ischemic heart disease (SIHD) is a predominant contributor to morbidity and mortality in the older adult population. Although results from clinical trials demonstrate that chronological age is a predictor of poor health outcomes, the current management approach remains suboptimal due to insufficient representation of older adults in randomized trials and the inadequate consideration for the interaction between biological aging, concurrent geriatric syndromes, and patient preferences. A shift towards a more patient-centered approach is necessary for appropriately and effectively managing SIHD in the older adult population. In this review, we aim to demonstrate the distinctive needs of older adults who prioritize holistic health outcomes like functional capacity, cognitive abilities, mental health, and quality of life alongside the prevention of major adverse cardiovascular outcomes reported in cardiovascular clinical trials. An individualized, patient-centered approach that involves shared decision-making regarding outcome prioritization is needed when any treatment strategy is being considered. By prioritizing patients and addressing their unique needs for successful aging, we can provide more effective care to a patient population that exhibits the highest cardiovascular risks.

Factors related to subjective well-being among community-dwelling older adults living alone: A stratified analysis by sex and marital status from the JAGES

BACKGROUND

Previous cross-sectional studies suggest that negative health outcomes such as mortality, social isolation, loneliness, and depression among older adults living alone vary by sex and marital status, with men often worse off than women and unmarried people worse off than married people. However, limited evidence exists from longitudinal studies regarding whether positive health outcomes such as subjective well-being (SWB) also vary by sex and marital status. The focus by sex and marital status on the positive health outcomes and diverse profiles of older adults living alone is important for public health in the near future. Therefore, the purpose of this study was to identify changes in SWB over time and its associated factors by sex and marital status among older adults living alone in the community using a longitudinal study in a representative population.

METHODS

This was a longitudinal study using data from the Japan Gerontological Evaluation Study. This study is the first to reveal differences in SWB and related factors over 3 years among older adults living alone in the community (n = 8,579) who were stratified by sex and marital status (married men, non-married men, married women, and non-married women).

RESULTS

Women moved to higher levels of SWB than did men, and married individuals moved to higher levels of SWB than did unmarried individuals. Independent functioning factors and interpersonal factors were significantly associated with SWB for married men and married women, but for unmarried women, the association by interpersonal factors was more pronounced, and for unmarried men, only limited emotional support and health promotion activities were significant among the interpersonal factors.

CONCLUSIONS

This study revealed that among older adults living alone, changes in SWB over time and the independent functioning factors and interpersonal factors associated with this change varied by sex and marital status among older people living alone. These findings are useful for policy-making and guiding intervention activities to promote SWB in a society in which the environment for older adults living alone is changing dramatically.

Cognition in older adults with healthy aging: analysis of the Mexican Health and Aging Study 2012-2015

Introduction

Maintaining older adults' health and well-being can be achieved through the optimization of physical and mental health, while preserving independence, social participation, and quality of life. Cognitive change has been described as a normal process of aging and it involves domains such as processing speed, attention, memory, language, visuospatial abilities, and executive functioning, among others.

Objective

To describe cognitive changes in older adults with healthy aging.

Methods

This is a study that involved data from 14,893 and 14,154 individuals aged >60 years or older from the 2012 and 2015 waves, respectively, who participated in the Mexican Health and Aging Study (MHAS). Participants with healthy aging were identified and described in the MHAS-2012 wave and followed to 2015. Eight cognitive domains evaluated in the Cross-Cultural Cognitive Evaluation (CCCE,) as well as sociodemographic and health characteristics, were described. Criteria for healthy aging involved the following: CCCE ≥ -1.5 standard deviations above the mean on reference norms, independence on basic and instrumental activities of daily living, self-reported "life close to ideal," and preserved functional and social performance.

Results

From a total of n = 9,160 older adults from the MHAS-2012 wave, n = 1,080 (11.8%) had healthy aging. In the healthy aging group, the median age was 67 years (IQR: 63-73), 58.1% were female and the median for education was 6 (IQR: 3-8) years. The mean CCCE score was 57 (SD: 16.9) points. In the MHAS-2012 cross-sectional analysis, except for orientation, visuospatial abilities, and verbal fluency, all cognitive domain scores were lower with passing age. When comparing cognitive domain scores in the 225 older adults identified with healthy aging between the 2012 and 2015 MHAS waves, there were almost no observable differences.

Conclusion

In the cross-sectional analysis, Mexican adults with healthy aging had lower scores in the verbal learning memory, visual scanning, numeracy, visual memory, and verbal recall domains', as well as lower global cognitive scores in the higher age groups. There were no cognitive changes in the 3 year follow-up, except for a lower gradient of scores in the verbal recall memory domain. Longer prospective studies are needed to characterize greater cognitive changes.

Developmental trajectories of successful aging among older adults in China: Evidence from the China Health and Retirement Longitudinal Study

This study aimed to identify potential trajectory groups of successful aging in older adults and to explore the influencing factors of each trajectory group. We used four waves of longitudinal data from the China Health and Retirement Longitudinal Study from 2011 to 2018, which involved 1,949 older adults. The developmental trajectories were determined using growth mixture modeling (GMM), and the influencing factors of each trajectory group were identified using multinomial logistic analysis. We identified three different groups of successful aging trajectories: high level-declining group (45%), medium level-declining group (39%), and low level-steady group (16%). Gender, education, marital status, place of residence, self-rated health, life satisfaction, and retirement pension were the influencing factors for the high level-declining group. Influencing factors for the medium level-declining group included gender, education, self-rated health, life satisfaction, and retirement pension. Healthcare professionals should formulate targeted measures according to different trajectory categories to promote successful aging in older adults.

A longitudinal study of disability in activities of daily living and activity restriction‐induced fear of falling among Korean older people

AIM

This study examined the effects of the fear of falling (FOF) alone and fear-associated activity restriction (FAR) on future activities of daily living (ADL) disability and analysed predictors of ADL disability among community-dwelling older people with and without FAR.

DESIGN

This prospective study involved secondary data analysis of the Korean Longitudinal Study of Aging.

METHODS

We obtained data from 5074 community-dwelling older adults. Generalized estimating equations were used to identify the predictors of changes in ADL disability between 2008 and 2018.

RESULTS

Compared with FOF alone, FAR was significantly related to changes in ADL disability. Being older, living with others and having poor self-rated health status were associated with future ADL disability in participants without FAR. Weakened grip strength and social engagement were associated with future ADL disability in those with FAR. Nurses must consider the impact of FAR on future ADL decline and implement tailored interventions.

Alaska native successful ageing in Northwest Alaska: how family impacts how one ages in a good way

aged well, yet today they experience high rates of illness and lower access to care because of colonisation. Aand this research explores successful ageing from an AN perspective or what it means to achieve "Eldership" in the rural Northwest Alaska. A community-based participatory research approach was used to engage participants at every stage of the research process. Semi-structured interviews were conducted with 16 AN men and 25 women and the interviews were professionally transcribed. Kleinman's explanatory model served as the foundation of the questionnaire to gain a sense of the beliefs about ageing and guide the thematic analysis to establish an AN understanding of successful ageing. The foundation of the Norton Sound southern sub-region Model of Successful Ageing is the reciprocal relationship between Elders and family which enables Elders to access meaningful activities, including Native ways of life, physical health, spirituality, and emotional well-being. Community-based interventions should foster opportunities for Elders to share their Native way of life alongside family and community members, which will enable them to remain physically active, maintain healthy emotional well-being, continue engaging in spiritual practices, and contribute to the health and well-being of families.

Prevalence of healthy aging among community dwelling adults age 70 and older from five European countries

BACKGROUND

To compare the prevalence of healthy aging among adults age 70 and older from 5 European countries recruited for the DO-HEALTH clinical trial. Participants were selected for absence of prior major health events.

METHODS

Cross-sectional analysis of DO-HEALTH baseline data. All 2,157 participants (mean age 74.9, SD 4.4; 61.7% women) were included and 2,123 had data for all domains of the healthy aging status (HA) definition. HA was assessed based on the Nurses` Health Study (NHS) definition requiring four domains: no major chronic diseases, no disabilities, no cognitive impairment (Montreal Cognitive Assessment, MoCA ≥25), no mental health limitation (GDS-5 <2, and no diagnosis of depression). Association between HA and age, BMI, gender, and physical function (sit-to-stand, gait speed, grip strength) was assessed by multivariate logistic regression analyses adjusting for center.

RESULTS

Overall, 41.8% of DO-HEALTH participants were healthy agers with significant variability by country: Austria (Innsbruck) 58.3%, Switzerland (Zurich, Basel, Geneva) 51.2%, Germany (Berlin) 37.6%, France (Toulouse) 36.7% and Portugal (Coimbra) 8.8% (p <0.0001). Differences in prevalence by country persisted after adjustment for age. In the multivariate model, younger age (OR = 0.95, 95% CI 0.93 to 0.98), female gender (OR = 1.36, 95% CI 1.03 to 1.81), lower BMI (OR = 0.94, 95% CI 0.91 to 0.96), faster gait speed (OR = 4.70, 95% CI 2.68 to 8.25) and faster performance in sit-to-stand test (OR = 0.90, 95% CI 0.87 to 0.93) were independently and significantly associated with HA.

CONCLUSIONS

Despite the same inclusion and exclusion criteria preselecting relatively healthy adults age 70 years and older, HA prevalence in DO-HEALTH varied significantly between countries and was highest in participants from Austria and Switzerland, lowest in participants from Portugal. Independent of country, younger age, female gender, lower BMI and better physical function were associated with HA.

TRIAL REGISTRATION

DO-HEALTH was registered under the protocol NCT01745263 at the International Trials Registry ( clinicaltrials.gov ), and under the protocol number 2012-001249-41 at the Registration at the European Community Clinical Trial System (EudraCT).

Exploring the Relationships Between Four Aging Ideals: A Bibliometric Study

When examining research articles on the aging strategies, four ideals (i.e., successful aging, healthy aging, productive aging and active aging) could be explored by conducting bibliometric analyses. For the literature analysis, general information on the four aging ideals was understood through visualization analysis; the intellectual base and research hotspots were intuitively observed. CiteSpace was used as the method to conduct the co-occurrence analysis of keywords in order to obtain research trends and cutting-edge knowledge in the field of aging-related policies. Subsequently, the study revealed the nature of the link between these four aging ideals and disclosed the connection between their fundamental principles. The study ultimately enhanced the understanding of the diverse contexts that have impacted the way in which these ideals influence policy, which has caused dissimilar strategies for policy development. The study also extended the discussion of the definitions of and relationships between these four ideals with the goal of identifying new directions for aging-related practice and providing innovative insights and references for investigators.

Gerontechnological factors affecting successful aging of elderly

In this article, the gerontological factors affecting the successful aging of the elderly have been uncovered, the quality of life and successful aging issues have been related to gerontology and investigated on a different dimension. It has been emphasized that the importance of gerontechnology on the successful aging, creation of awareness through formal and non-formal education, qualitative and quantitative researches should be increased. Qualitative and quantitative researches on the subject were evaluated together, gerontology and gerontechnology were considered together with successful aging, and gerontology functions and ergonomics should be taken into consideration in increasing quality of life. In addition, the concept of geronsafety, a new concept in gerontology, has been put forward, emphasizing the effects of safety on gerontology and successful aging.

Association Between Dietary Patterns in Midlife and Healthy Ageing in Chinese Adults: The Singapore Chinese Health Study

OBJECTIVE

To examine the associations between dietary patterns in midlife and likelihood of future healthy ageing in Chinese older adults.

DESIGN

Prospective population-based study.

SETTING AND PARTICIPANTS

We included 14,159 participants aged 45-74 years who were free from cancer, cardiovascular disease, or diabetes at baseline (1993-1998) from the Singapore Chinese Health Study.

METHODS

Dietary intakes in midlife were assessed by a validated food frequency questionnaire at baseline. Diet quality was scored according to the alternate Mediterranean diet (aMED), the Dietary Approaches to Stop Hypertension (DASH) diet, the alternative Healthy Eating Index (AHEI)-2010, overall plant-based diet index (PDI), and healthful plant-based diet index (hPDI). Healthy ageing was assessed at the third follow-up visit (2014-2016), which occurred about 20 years after the baseline visit, and was defined as the absence of 10 chronic diseases, no impairment of cognitive function, no limitations in instrumental activities of daily living, no clinical depression at screening, good overall self-perceived health, good physical functioning, and no function-limiting pain among participants who had survival to at least 65 years of age. Multivariable-adjusted logistic regression models were applied to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between each dietary pattern score and healthy ageing.

RESULTS

About 20.0% of participants met the healthy ageing criteria. The OR (95% CI) for healthy ageing comparing the highest with the lowest quartile of diet quality scores was 1.52 (1.31-1.77) for aMED, 1.53 (1.35-1.73) for DASH, 1.39 (1.23-1.57) for AHEI-2010, 1.34 (1.18-1.53) for PDI, and 1.45 (1.27-1.65) for hPDI (all P-trend < .001). Each standard deviation increment in different diet quality scores was associated with 12% to 18% higher likelihood of healthy ageing.

CONCLUSIONS AND IMPLICATIONS

In this Chinese population, adherence to various healthy dietary patterns at midlife is associated with higher likelihood of healthy ageing at later life.

Aging Well on the Autism Spectrum: An Examination of the Dominant Model of Successful Aging

There is a gap in our knowledge of aging with autism. The present study examined the applicability of the popular gerontology concept of "aging well" to autistic adults. Using survey data, a model of "aging well" was operationalised and applied to 92 autistic adults and 60 controls. A very small proportion (3.3%) of autistic adults were found to be aging well. Significantly less autistic adults were "maintaining physical and cognitive functioning" and "actively engaging with life" in comparison to controls. Whilst important differences in health and functioning status were found, the current dominant model of "aging well" is limited for examining autistic individuals. Suggested adjustments include development of a broader, more flexible and strengths -based model.

Cross-cultural adaptation and psychometric properties of the Brazilian Portuguese version of successful aging scale in community-dwelling older adults

There is a growing consensus regarding the multidimensional nature of successful aging (SA), including both the biomedical and psychosocial domains of the aging process. The Successful Aging Scale (SAS) is a self-rated instrument addressing both of these components. The aim of this study was to analyze the psychometric properties of the Brazilian Portuguese version of the SAS (SAS-B) with regard to reliability and validity in 949 Brazilian community-dwelling older adults (53.60% women; M = 69.49 years; standard deviation = 7.67). Confirmatory factorial analysis (CFA) was performed to provide evidence on its structural validity. Convergent and divergent validity was studied by means of examining the relationships of SAS-B with scales concerning resilience, life satisfaction, self-esteem, social support, perceived stress, and health, as well as mental health. The CFA showed that the SAS-B is multidimensional with three correlated factors (χ² /df = 2.74; standardized root mean square residual = 0.03; root mean square error approximation = 0.04; comparative fit index = 0.91), and its factors showed adequate reliability (ω = 0.70 for Healthy living habits, ω = 0.69 for Adaptive coping, and ω = 0.70 for Engagement with Life). Convergent and divergent validity was endorsed by correlations with related factors. The SAS-B is a reliable and valid self-rated instrument to measure the SA from a multidimensional perspective.

Robust older adults in primary care: factors associated with successful aging

OBJECTIVE

To estimate the prevalence of robustness among older adults assisted in primary health care and identify factors in successful aging.

METHODS

This is a cross-sectional study conducted with older adults in Northern Minas Gerais, Brazil. Two questionnaires were used for data collection: the Brazilian Older Americans Resources and Services Multidimensional Function Assessment Questionnaire (BOMFAQ) and the Clinical-Functional Vulnerability Index IVCF-20). The adjusted prevalence ratios were obtained by robust Poisson regression. Statistical analysis was performed for older adults in general (60 to 107 years) and stratified by age: from 60 to 79 years and 80 years or more.

RESULTS

A total of 1,750 older adults aged 60 to 107 years participated; between them, 48.7% were robust. Older adults aged 60 to 79 years (n = 1,421) and 80 years or more (n = 329) had a prevalence of robustness of 55.4% and 19.3%, respectively. Some factors associated with successful aging were: positive self-perception of health, dancing habits, walking habits, absence of cognitive impairment, absence of depressive symptoms and polypathology, as well as daily life independence. After adjustment by age, the absence of polypathology and independence for activities of daily living stand out for robustness between 60 and 79 years; in those aged 80 years and over, independence for activities of daily living and dance practice presented greater strength of association.

CONCLUSION

The prevalence of robust older adults in primary care is considered satisfactory for the older population in general but decreases with age and is associated with the absence of diseases and disabilities. These results denote the need to redesign the health care system, focusing on promoting and preventing clinical-functional vulnerability.

What attributes of successful aging are important to older adults? The development of a multidimensional definition of successful aging

Older adults' experiences and perspectives have been missing in the quest to develop a unified definition of successful aging. Through an online survey using convenience sampling, respondents (N = 477) were asked to report how important 25 specific attributes of successful aging, originating from published literature that examined successful aging from the perspective of older adults, were to them as they age. Over 90% of respondents reported 11 attributes as important or very important to them as they age, which included "remaining free of chronic diseases" and "feeling good about myself." A factor analysis (N = 462) resulted in four dimensions explaining 57.06% of the variance: Adaptation and Coping; Being Healthy; Self-Determination; and Social Relationships and Interactions. The findings revealed older adults' definition of what is important to them as they age is multidimensional, with having access to affordable health care and remaining alert and mentally active as critical elements followed by elements of self-determination, coping, and physical and social health. Future research should replicate the study with diverse populations to continue to refine a definition of successful aging that could influence program development and intervention approaches in health and social services.

Risk for physical dependence in community-dwelling older adults: The role of fear of falling, falls and fall-related injuries

BACKGROUND

Falls and fall-related injuries along with fear of falling (FoF) seem to restrict activities of daily living (ADL), resulting in physical dependence. However, it is still unclear how falls and related injuries or FoF by themselves explain general and specific ADL dependence.

OBJECTIVES

To investigate the relationships between falls and related injuries, FoF and physical dependence on ADL in community-dwelling older adults, controlling for age, gender, physical activity and physical fitness as confounders.

METHODS

This cross-sectional descriptive study assessed 588 community-dwelling older adults. Falls and fall-related injuries, ADL dependence on basic, instrumental and advanced activities, FoF, demographic characteristics and health conditions were assessed through a questionnaire. Physical activity was measured through the International Physical Activity Questionnaire. Physical fitness was assessed by the Senior Fitness Test and the Fullerton Advanced Balance Scale. Body composition was measured through bioimpedance.

RESULTS

Severe injuries occurrence increased the likelihood of moderate and high physical dependence by 3 and 6 times, while FoF increased this likelihood by 3 and 7 times, respectively. Also, the occurrence of previous falls, resulting in severe injuries, increased the likelihood of dependence in two instrumental ADL (3 and 4 times), while FoF increased this likelihood in numerous basic, instrumental and advanced ADL (2-3 times). The FoF was shown to explain overall physical functioning dependence, by itself, representing a constraint on the performance of most basic, instrumental and advanced ADL.

CONCLUSION

The FoF showed to be a greater threat to ADL dependence than falls and related injuries. Assessment guidelines for older adults living in the community should include the FoF in clinical evaluation.

IMPLICATIONS FOR PRACTICE

Understand the isolated interplay of FoF and previous falls and injuries on ADL dependence among older adults allows healthcare professionals to perform more accurate clinical evaluations and develop more successful interventions to prevent further dependence.

Domains and Measurements of Healthy Aging in Epidemiological Studies: A Review

Purpose of the Study

Few studies have recommended the essential domains of healthy aging and their relevant measurement to assess healthy aging comprehensively. This review is to fill the gap, by conducting a literature review of domains and measures of healthy aging in epidemiological studies.

Design and Methods

A literature search was conducted up to March 31, 2017, supplemented by a search of references in all relevant articles in English. We made a final selection of 50 studies across 23 countries or regions.

Results

Nineteen studies applied Rowe and Kahn’s three standards to assess healthy aging. Thirty-seven studies measured physical capabilities mainly by (instrumental) activities of daily living. Cognitive functions were included in 33 studies. Nineteen of them applied Mini-Mental State Examination (MMSE). Twenty-six studies considered metabolic and physiological health, but they mainly asked the self-reported absence of diseases. Twenty-four studies assessed psychological well-being by employing diverse scales. Questions about participation in social activities were mainly asked to measure social well-being in 22 studies. Sixteen studies considered individuals’ general health status, which was mainly measured by self-rated health. Security questions were asked in five studies. Health behaviors were taken into account by three studies. Fifteen studies either applied SF-12/36 or developed health indices to assess healthy aging.

Implications

This review summarizes detailed scales or methods that have been used to assess healthy aging in previous epidemiological studies. It also discusses and recommends the essential domains of healthy aging, and the relevant instruments for further epidemiological research to use in the assessment of healthy aging.

A research on the effects of successful aging on the acceptance and use of technology of the elderly

The aim of the study is to analyze the effects of successful aging on technology acceptance and use behaviors, via developing a model. This study was conducted with 687 participants in five Retirement Rest Homes in Turkey. A model was developed to meet the study's research objectives using the scales of successful aging and the second unified theory of acceptance and use of technology. A path analysis was performed with Partial Least Squares (PLS) structural equation model. Struggle Against Difficulties (SAD) significantly predicted performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic motivation, price value, habit, and behavior intention, even though SAD did not predict USE. HLH significantly predicted performance expectancy, social influence and facilitating conditions; HLH did not predict effort expectancy, hedonic motivation, price 15 value, habit, behavior intention, and USE. It was revealed that successful aging affected the technology acceptance model in general except the use of technology. It is recommended for future studies that successful aging should be evaluated with varied model studies.

Successful ageing from old to very old: a longitudinal study of 12,432 women from Australia

OBJECTIVES

We examined the development of disease and disability in a large cohort of older women, the extent to which these conditions exempt them from being classified as successful agers and different trajectories of disease, disability and longevity across women's later life.

METHODS

We used survey data from 12,432 participants of the 1921-26 birth cohort of the Australian Longitudinal Study of Women's Health from 1996 (age 70-75) to 2016 (age 90-95). Repeated measures latent class analysis (RMLCA) identified trajectories of the development of disease with or without disability and according to longevity. Bivariate analyses and multivariable multinomial logistic regression models were used to examine the association between participants' baseline characteristics and membership of the latent classes.

RESULTS

Over one-third of women could be considered to be successful agers when in their early 70s, few women could still be classified in this category throughout their later life or by the end of the study when they were in their 90s (~1%). RMLCA identified six trajectory groups including managed agers long survivors (9.0%) with disease but little disability, usual agers long survivors (14.9%) with disease and disability, usual agers (26.6%) and early mortality (25.7%). A small group of women having no major disease or disability well into their 80s were identified as successful agers (5.5%). A final group, missing surveys (18.3%), had a high rate of non-death attrition. Groups were differentiated by a number of social and health factors including marital status, education, smoking, body mass index, exercise and social support.

CONCLUSIONS

The study shows different trajectories of disease and disability in a cohort of ageing women, over time and through to very old ages. While some women continue into very old age with no disease or disability, many more women live long with disease but little disability, remaining independent beyond their capacity to be classified as successful agers.

The curvilinear relationship of early-life adversity and successful aging: the mediating role of mental health

OBJECTIVES

The steeling effect suggests that early-life adversity can have a beneficial impact later in life. However, little is known about its underlying mechanisms and long-term outcomes . The study aimed to examine the role of early-life adversity (ELA) on successful aging, and whether this relationship can be explained by mental and physical health.

METHOD

Socio-demographics, early-life adversity (ELA), individual quality of life (iQoL), and mental and physical health of 270 individuals (M_age = 66.82 years, 71.5% female) were assessed. Polynomial regressions and mediation analyses were conducted.

RESULTS

Significant inverse U-shaped associations were found between ELA and iQoL (β = -.59, p = .005) and between ELA and mental health (β = -.64, p = .002), but not between ELA and physical health. Furthermore, mental health significantly mediated the relationship between ELA and iQoL (b = -.84, BCa CI [-1.66, -.27]).

CONCLUSION

Highest level of individual quality of life (i.e. successful aging) was related to a moderate amount of ELA. Additionally, mental health significantly mediated this relationship. These findings suggest that some amount of ELA could be beneficial for successful aging. Resource-focused interventions are needed to improve health and promote successful aging for an underdetected, at-risk subgroup with low early-life adversity.

Controlling active ageing: a study of social imaginaries of older people in Chile

A key issue in understanding the social lives of older people is how active they are in coping with the demands of ageing. Often the ‘successfulness’ of ageing is measured with medical and biological criteria. While the notion of ‘active ageing’ is more appealing and neutral, its meaning is often obscured, fragmented or inconsistent. Our aims in this study were to establish ‘active ageing’ as a process in which older people try to take control of their lives by conforming to or resisting different social imaginaries of later life, and to explore individuals’ strategies for making the best use of available resources and fending off potential risks of social exclusion. We adopted a two-stage research design. First, we produced artistic images that corresponded to social imaginaries of tensions in ageing in three social domains (politics, mass media and older people). Then, we used these images as stimuli in interviews with a balanced sample of 32 middle-aged and older residents of Santiago, Chile, to discover their strategies for coping with these tensions. Although imaginaries of ageing tended to describe ageing in terms of restrictions and stereotypes, we found diverse and increasingly flexible life projects and expectations of activity in later life.

Social determinants, health status and 10-year mortality among 10,906 older adults from the English longitudinal study of aging: the ATHLOS project

Background

In either rich or poor countries, people’s health widely depends on the social conditions in which they live and work – the social determinants of health. The aim of the present work was to explore the association of educational and financial status with healthy aging and mortality.

Methods

Data from the English Longitudinal Study of Aging (ELSA) were studied (n = 10,906 participants, 64 ± 11 years, 55% women). A set of 45 self-reported health items and measured tests were used to generate a latent health metric reflecting levels of functioning referred to as health metric (higher values indicated better health status). Overall mortality after 10-years of follow-up (2002–2012) was recorded.

Results

Both education and household wealth over time were positively associated with the health metric (p < 0.001) and negatively with overall mortality (p < 0.001). Lifestyle behaviors (i.e., physical activity, smoking habits and alcohol consumption) mediated the effect of education and household wealth on the health metric and the latter mediated their effect on overall mortality.

Conclusions

In conclusion, reducing socioeconomic disparities in health by improving the access to education and by providing financial opportunities should be among the priorities in improving the health of older adults.

The Usability Study of a Proposed Environmental Experience Design Framework for Active Ageing

Growing ageing population today may be necessitating building design decision makers to reconsider the indoor environmental quality (IEQ) standards in a way that accommodates senior occupants’ diverse and individual needs and demands. An experience design approach to rationalising and individualising end-user experience on how to utilise tangible products may serve to reflect user perceptions. Generally, architectural design practices tend to incorporate neither IEQ monitoring and analysis data, nor environmental experience design today. In response to the need for filling this gap, the authors of this paper conducted a feasibility study previously that led to structuring and defining an ‘Environmental Experience Design’ (EXD) research framework. Based on the previous case study on the collective spatial analysis and IEQ monitoring results, this paper further explored the usability and applicability of this proposed EXD framework particularly to the previously documented aged care facility in Victoria, Australia, which has been stressing active ageing agendas. This EXD framework usability experiment helped to build the capacity for engaging the subjectivity and objectivity of end users’ expectations, desires, and requirements in the architectural design thinking process. Nonetheless, due to the limitation of this initial and fundamental usability study’s resources and the objective, the necessity of adjusting the scale and scope of EXD analyses emerged. Moreover, the universality of this EXD research framework usage under various architectural typologies and user conditions yet require further attempts and investigations.

[Self-care: New evidence for its measurement in older adults]

INTRODUCTION

A major challenge in today's society is getting older people, not only live longer, but to have a better life, and achieve successful aging. Self-care has been identified as relevant construct in its relation to physical, psychological, and social health. Therefore, this paper aims to provide first evidence of the psychometric properties of a scale to assess self-care in older people.

MATERIAL AND METHODS

The sample consisted of 443 people aged between 60 and 80years (M=66.11, SD=4.72), all of them currently participating in lifelong learning programs. There were 64.2% women, and most participants were married (73.7%). They were asked to complete the Self-Care for Older People Scale (SCOPS), the SF-8 Health Perception scale and, the Life Satisfaction scale (SWLS). Data were analysed using confirmatory factor analysis, and scale correlations between self-care and variables from its nomological network.

RESULTS AND CONCLUSIONS

The tested model provided an adequate fit to the data: χ²(23)=64.257 (P<.001); comparative fit index (CFI)=.936; Tucker Lewis Index (TLI) =.899; standardized root mean square residual (SRMR) =.070; root mean square error of approximation (RMSEA) =.064 (.046-.083), supporting the original structure of three factors: physical, social, and internal self-care. These factors also showed statistically significant correlations with two important variables of their nomological network, perceived health and life satisfaction.

Prevalence and related factors of Active and Healthy Ageing in Europe according to two models: Results from the Survey of Health, Ageing and Retirement in Europe (SHARE)

BACKGROUND

Active and Healthy Ageing (AHA) is the process of optimizing opportunities related to health, participation, and safety in order to improve quality of life. The approach most often used to measure AHA is Rowe and Kahn's Satisfactory Ageing model. Nonetheless, this model has limitations. One of the strategic objectives of the WHO Global Strategy and Action Plan (2016) is to improve Healthy Ageing measurement. Our objectives were to compare two models of assessing AHA and further compare the results by country and sociodemographic variables.

METHODS

This was a cross-sectional, observational analysis of a representative sample of the general population aged 50 years and older in Europe. The data analysed were obtained by the Study of Health, Ageing and Retirement in Europe (SHARE). The dependent variable was AHA and its dimensions, measured using the Rowe and Kahn AHA model (AHA-B) and the authors' model based on the WHO definition (AHA-BPS). A descriptive analysis and multivariate models of binary logistical regression were developed.

RESULTS

The sample consisted of 52,641 participants (mean age 65.24 years [SD = 10.18; Range = 50-104], 53.2% women). Healthy Ageing prevalence in the AHA-B model was 23.5% (95%CI = 23.1%-23.9%). In the AHA-BPS model, this prevalence was 38.9%. In both models, significant variations were observed between countries, and were distributed along a north-western to south-eastern gradient. The sociodemographic variables associated with the absence of AHA were advanced age, female sex, death of spouse, low educational level, lack of employment, and low financial status. Comparing the two models, the strength of association between absence of AHA and advanced age (85 years and older) was four times greater in the AHA-B model.

CONCLUSIONS

Our results showing differences between these two models provide evidence that the AHA-BPS model does not penalize older age and is more likely to characterize AHA from a health promotion perspective.

Positive perception of aging is a key predictor of quality-of-life in aging people

OBJECTIVE

We conducted a cross-sectional survey in France in a cohort over 55 years of age to characterize the impact of psychological dimensions on quality-of-life (QoL).

METHODS

The predictors of QoL in relation with aging were studied using an adapted quality-of-life model, based on emotional, cognitive and physical symptoms, functional status, and general health perception. Adding psychological dimensions such as self-esteem, psychological distress, perceptions of ageing and coping, was hypothesized to improve the QoL model. Responses were analyzed using structural equation modeling and path analysis.

RESULTS

The study involved 258 participants, mean age 66.9±7.9 years. Psychological distress and positive perception of aging exhibited the strongest direct impact on QoL (p<0.0001). Psychological distress also appeared to be mediator on QoL for perceived health status, self-esteem and negative perception of aging. Coping centred on emotion exhibited direct impact on self-esteem and so, indirect impact on QoL (p = 0.0002). Perception of personal financial situation (p = 0.0007) and coping centred on social support (p = 0.02) appeared as direct mediators influencing QoL.

CONCLUSIONS

Psychological dimensions are predictors of QOL and have to be taken into account to maximize the resources with a view to successful aging. Further interventions targeting successful aging should focus on positive perception aging.

What Is Successful Aging? A Psychometric Validation Study of Different Construct Definitions

Background and Objectives

We examined the validity of 5 successful aging (SA) operationalizations that assessed different facets of the SA construct (cognitive and physical health and disability; well-being; social engagement).

Research Design and Methods

A total of 2,478 participants (mean age = 82.5 years, standard deviation [SD] = 3.47) were studied. We used confirmatory factor analysis to investigate the relationships between facets and to determine the convergent validity as well as short-term (1.5 years) and long-term (4.5 years) predictive validity of the 5 SA operationalizations for measures of quality of life (QoL) and objective health outcomes.

Results

A general SA operationalization that included all SA facets but also allowed differences between them showed the best model fit and construct validity. A biomedical operationalization of SA that excluded either the well-being or the social engagement facet showed lower convergent and predictive validity for subjective measures (e.g., QoL) but higher associations with objective measures (e.g., health). A purely psychosocial SA operationalization that excluded the physiological facet did not allow good prediction of objective health outcomes.

Discussion and Implications

Our results suggest that a well-balanced SA operationalization should include measures assessing health, disability, well-being, and social engagement.

Prevalence of and factors associated with successful aging in Brazilian older adults: Frailty in Brazilian older people Study (FIBRA RJ)

AIM

We aimed to estimate the factors associated with the biomedical dimension of successful aging (SA) and its prevalence in older Brazilian individuals. The conceptual framework for this approach relies on the considerable variation in the biophysiological effects of aging and the need to understand the factors that influence this process.

METHODS

Data from a total of 845 older adults were analyzed. SA operationalization included the following criteria: good physical and cognitive performance, absence of disabilities, and good health conditions. Descriptive analyses were used to estimate the prevalence of SA, and the factors associated with SA were assessed using multivariate logistic regressions.

RESULTS

The overall prevalence of SA was 25%, and the associated factors were the absence of (OR 10.5, 95% CI 5.2-21.1) or fewer than two physical morbidities (OR,3.5, 95% CI 2.1-5.9), body mass index in the overweight range (OR 1.8, 95% CI 1.02-3.3), absence of depression (OR ,2.1, 95% CI 1.07 = 4.1), high levels of physical activity (OR 1.88, 95% CI 1.14-3.2), high levels of social participation (OR 2.07, 95% CI 1.16-3.4) and younger age (65-74 years, OR 4.27, 95% CI 1.79-10.1; 75-84 years, OR 2.7, 95% CI 1.18-6.41).

CONCLUSIONS

A small proportion of older adults met the criteria defining successful aging. Despite the great impact of biological determinants, modifiable social and lifestyle factors predicted successful aging in this population, suggesting that health promotion targeting behavioral changes might lead to tangible benefits for health and well-being in old age.

Capturing the Diversity of Successful Aging: An Operational Definition Based on 16-Year Trajectories of Functioning

Purpose of the Study

To determine the prevalence and extent of successful aging (SA) when various suggestions proposed in the previous literature for improving models of SA are incorporated into one holistic operational definition. These suggestions include defining and measuring SA as a developmental process, including subjective indicators alongside more objective ones, and expressing SA on a continuum.

Design and Methods

Data were used from 2,241 respondents in the Longitudinal Aging Study Amsterdam, a multidisciplinary study in a nationally representative sample of older adults in the Netherlands. Latent class growth analysis was used to identify successful 16-year trajectories within nine indicators of physical, cognitive, emotional, and social functioning. SA was quantified as the number of indicators in which individual respondents showed successful trajectories (range 0-9).

Results

Successful trajectories were characterized by stability, limited decline, or even improvement of functioning over time. Of the respondents, 39.6% of men and 29.3% of women were successful in at least seven indicators; 7% of men and 11% of women were successful in less than three indicators. Proportions of successful respondents were largest in life satisfaction (>85%) and smallest in social activity (<25%). Correlations of success between separate indicators were low to moderate (range r = .02-.37).

Implications

Many older adults age relatively successfully, but the character of successful functioning over time varies between indicators, and the combinations of successful indicators vary between individuals.

Education and Successful Aging Trajectories: A Longitudinal Population-Based Latent Variable Modelling Analysis

As the population ages, interest is increasing in studying aging well. However, more refined means of examining predictors of biopsychosocial conceptualizations of successful aging (SA) are required. Existing evidence of the relationship between early-life education and later-life SA is unclear. The Successful Aging Index (SAI) was mapped onto the Cognitive Function and Aging Study (CFAS), a longitudinal population-based cohort (n = 1,141). SAI scores were examined using growth mixture modelling (GMM) to identify SA trajectories. Unadjusted and adjusted (age, sex, occupational status) ordinal logistic regressions were conducted to examine the association between trajectory membership and education level. GMM identified a three-class model, capturing high, moderate, and low functioning trajectories. Adjusted ordinal logistic regression models indicated that individuals in higher SAI classes were significantly more likely to have higher educational attainment than individuals in the lower SAI classes. These results provide evidence of a life course link between education and SA.

Modeling Successful Aging Over Time in the Context of a Disaster

Objective

Positing that successful aging (SA) has independent, yet related components that are both objective and subjective, we examine how the indicators of SA change over time and how exposure to a disaster affects the developmental course of SA.

Method

Data were gathered from 5,688 people aged 50-74 years living in New Jersey who participated in baseline telephone interviews between 2006 and 2008 and then were reassessed up to four times over the following 9 years. Multilevel mixed effects models were used to examine change in objective and subjective SA over time and to evaluate the impact of Hurricane Sandy on SA.

Results

Over the 9-year period, controlling for age, gender, education, and income, average levels of both subjective SA and objective SA declined. People exposed to Hurricane Sandy experienced sharper declines in subjective SA and indicators of objective SA (pain and functional ability) than people not exposed.

Discussion

Findings have important implications for expanding our conceptualization of SA, clarifying the measures used to understand SA, and the importance of accounting for the effects of disasters on SA.

Concordance and Discordance of Self-Rated and Researcher-Measured Successful Aging: Subtypes and Associated Factors

Objectives

To investigate subtypes of successful aging (SA) based on concordance and discordance between self-rated and researcher-defined measures and their associations with demographic, psychosocial, and life satisfaction factors.

Method

We used multinomial logistic regression models to analyze 2013 cross-sectional survey data from 1,962 persons aged 65 and older in Shanghai that measured self-rated successful aging (SSA) with a single global assessment and researcher-defined successful aging (RSA) with a cumulative deficit index reflecting physical, physiological, cognitive, psychological, and social engagement domains. We generated four subtypes based on these two dichotomous variables: nonsuccessful aging (non-SA; meeting neither the criterion of RSA nor the criterion of SSA), RSA-only (meeting the criterion of RSA-only but not the criterion of SSA), SSA-only (meeting the criterion of SSA-only but not the criterion of RSA), and both-successful aging (both-SA; meeting both criteria of RSA and SSA).

Results

In the sample, 32% were nonsuccessful agers, 7% RSA-only, 34% SSA-only, and 27% successful agers. Female gender and older age were associated with lower likelihood of RSA-only and both-SA relative to non-SA, but with greater likelihood of SSA-only. Good socioeconomic conditions and social networks were associated with greater likelihood of SSA-only and both-SA relative to non-SA or RSA-only. Satisfaction with life domains was robustly and positively associated with good successful aging outcomes.

Discussion

Researcher-defined successful aging and self-rated successful aging are different measures with distinct social correlates. Subtypes of concordance and discordance provide a more holistic biopsychosocial conceptualization of successful aging.

Prevalence and related factors of successful aging among Chinese rural elders living in nursing homes

Few studies focus on the prevalence and related factors of successful aging (SA) among Chinese rural elders living in nursing homes. This study aims to make an operational definition of successful aging, estimate the prevalence of SA, and identify factors related to SA among Chinese rural elders living in nursing homes. Data for this cross-sectional study were collected by face-to-face interviews in five rural public nursing homes. A total of 205 elders aged 60 years and above were asked to answer a series of questions. Descriptive analysis, independent sample t tests, χ² tests, and multivariate logistic regression were used to show the prevalence and related factors of SA. The prevalence of SA in this population is 17.6% based on a multidimensional construct composed of: few chronic diseases, good cognitive and physical functioning, good mental health, and active social engagement. The logistic regression results indicate that successful agers are more likely to be younger, married, resilient, and better off economically, whereas gender, education, and social support are not related to SA independently. This model accounts for 45.8% of the variance in SA. These results suggest some tentative recommendations for elders, relevant decision-makers or employees in nursing homes, and administrative bodies. More rigorous longitudinal design is necessary to investigate the causality of the related factors and SA.

Trajectories of ageing well among older Australians: a 16-year longitudinal study

In this study we used individual differences concepts and analyses to examine whether older people achieve different ageing-well states universally or whether there are identifiable key groups that achieve them to different extents. The data used in the modelling were from a prospective 16-year longitudinal study of 1,000 older Australians. We examined predictors of trajectories for ageing well using self-rated health, psychological wellbeing and independence in daily living as joint indicators of ageing well in people aged over 65 years at baseline. We used group-trajectory modelling and multivariate regression to identify characteristics predicting ‘ageing well’. The results showed three distinct and sizeable ageing trajectory groups: (a) ‘stable-good ageing well’ (classified as ageing well in all longitudinal study waves; which was achieved by 30.2% of women and 28.0% of men); (b) ‘initially ageing well then deteriorating’ (50.5% women and 47.6% men); and (c) ‘stable-poor’ (not ageing well in any wave; 19.3% women and 24.4% men). Significant gender differences were found in membership in different ageing-well states. In the stable-poor groups there were 103/533 females which was significantly lower than 114/467 men (z-statistic = −2.6, p = 0.005); women had a ‘zero’ probability of progressing to a better ageing-well classification in later years, whilst males had a one-in-five probability of actually improving. Robust final state outcome predictors at baseline were lower age and fewer medical conditions for both genders; restful sleep and Australian-born for women; and good nutrition, decreased strain, non-smoker and good social support for men. These results support that ageing-well trajectories are influenced by modifiable factors. Findings will assist better targeting of health-promoting activities for older people.

Is car use related with successful aging of older adults? Results from the multinational Mediterranean islands study

PURPOSE

The aim of the present work was to evaluate the relation between car use and the level of successful aging of a random sample of older adults living in the Mediterranean basin.

METHODS

During 2005-2011, 2749 older (aged 65-100 years) from 22 islands and the rural Mani region (Peloponnesus) of Greece were voluntarily enrolled in the Mediterranean islands cross-sectional study. Sociodemographics, medical conditions, and dietary and lifestyle habits were derived throughout standard procedures. Car use was recorded with a standard binary question. A successful aging index ranging from 0-10 was used.

RESULTS

Older adults who used a car on regular basis had significantly higher levels of successful aging, as well as less prevalence of obesity and hypertension while were more physically active (P < .001). After adjusting for several confounders car use was still positively related with elderly islander's successful aging level (beta coefficient [95% confidence interval]: 0.65 [0.54-0.77]).

CONCLUSIONS

In conclusion, the activity of car use seems to be an indicator of quality of life among older adults, as measured through successful aging.

Successful aging among Chinese near-centenarians and centenarians in Hong Kong: a multidimensional and interdisciplinary approach

OBJECTIVES

This study applied a multidimensional model on a continuum to examine successful aging (SA) and investigated whether SA is associated with biomedical and psychosocial-demographic factors among Hong Kong Chinese near-centenarians and centenarians.

METHOD

A cross-sectional data analysis was performed on a geographically representative sample of 120 near-centenarians and centenarians with an age range of 95-108 years. We developed an integrated and cumulative Successful Aging Index (SAI) based on participants' performance in four dimensions: (1) physical and functional health (PF), (2) psychological well-being and cognition (PC), (3) social engagement and family support (SF), (4) economic resources and financial security (EF). To examine the criterion validity of SAI, we conducted a multiple binary logistic regression with interviewer-rated health. A multiple regression model was ran to investigate the independent biomedical and psychosocial-demographic correlates of SAI.

RESULTS

Results show that only 5.8% of participants attained SA in all four dimensions. PF had the least achievers, whereas the proportion was the highest in PC. SAI was significantly associated with interviewer-rated health and a high level of high-density lipoprotein cholesterol. Living with family or friends, high level of optimism, fewer diseases, and barriers to social activities were independent predictors of SAI score.

CONCLUSION

In the light of the lack of consensus on the constituents and assessment of SA especially among very old adults, our findings add to the extant literature by underscoring the importance of the multidimensional nature and the utility of an integrated and cumulative-based assessment of SA at the extreme of longevity.

Comparison of the Rowe-Kahn Model of Successful Aging With Self-rated Health and Life Satisfaction: The West of Scotland Twenty-07 Prospective Cohort Study

PURPOSE OF THE STUDY

With increasing longevity in industrialized populations, there is growing interest in what defines "successful aging" (SA). Various SA measures have been proposed but no consensus has been reached and many have been criticized for not representing the views and priorities of older people. We consider whether the Rowe-Kahn SA model captures older individual's perceptions of their own health and aging.

METHODS

Using two cohorts of 886 and 483 men and women from the West of Scotland Twenty-07 Study, aged around 57 and 76, respectively, we explored associations between Rowe-Kahn SA dimensions (absence of disease/disability; good physical/cognitive functioning; good interpersonal/productive social engagement) and four aspects of self-rated health and satisfaction (current general health; health for age; satisfaction with health; satisfaction with life).

RESULTS

Respondents' self-rated health and satisfaction was generally good but few had all six Rowe-Kahn dimensions positive, the conventional definition of SA. All individual positive SA dimensions were associated with better self-rated health and satisfaction. This was consistent across age, gender, manual/nonmanual occupations, and personality. The prevalence of good self-rated health and satisfaction increased with increasing numbers of positive SA dimensions.

IMPLICATIONS

The Rowe-Kahn model provides a functional definition of SA. Future work on ageing should include all Rowe-Kahn dimensions and consider SA as a continuum.

Older Adults' Online Dating Profiles and Successful Aging

This study examined how relevant Rowe and Kahn's three criteria of successful aging were to older adults' self-portrayals in online dating profiles: low probability of disease and disability, high functioning, and active life engagement. In this cross-sectional study, 320 online dating profiles of older adults were randomly selected and coded based on the criteria. Logistic regression analyses determined whether age, gender, and race/ethnicity predicted self-presentation. Few profiles were indicative of successful aging due to the low prevalence of the first two criteria; the third criterion, however, was identified in many profiles. Native Americans were significantly less likely than other ethnic groups to highlight the first two criteria. Younger age predicted presenting the first criterion. Women's presentation of the third criterion remained significantly high with age. The findings suggest that the criteria may be unimportant to older adults when seeking partners, or they may reflect the exclusivity of this construct.

Self-perceived uselessness is associated with lower likelihood of successful aging among older adults in China

BACKGROUND

Plenty of evidence has shown that self-perceived uselessness among older adults is negatively associated with successful aging in terms of good health in Western societies. It is unclear whether these findings are valid in China where living into older age is more selective due to high mortality at younger ages.

METHODS

Using five waves (2000, 2002, 2005, 2008/2009 and 2011/2012) of a large nationally representative survey in China with 29,954 observations from 19,070 older adults aged 65 and older, this study aimed to investigate the association between self-perceived uselessness and successful aging. Self-perceived uselessness was measured by a single item "with age, do you feel more useless?" with six answers: always, often, sometimes, seldom, never, and unable to answer. Successful aging was measured by independence in activities of daily living (ADL), independence in instrumental activities of daily living (IADL), unimpaired cognition, good life satisfaction, and good self-rated health. Logistic regression models were applied to each successful aging indicator after controlling for a rich set of covariates that included demographics, socioeconomic status, family/social support, and health practices. The models also adjusted for intraperson correlations across waves.

RESULTS

We found that self-perceived uselessness was negatively associated with successful aging among older adults aged 65 or older. Specifically, compared to never having self-perceived uselessness, always having such a perception was associated with 16-42 % lower odds of being ADL independent, IADL independent, cognitively unimpaired, and having good life satisfaction and good self-rated health. Often or sometimes having such a perception also reduced odds of aging successfully, although such reductions were less pronounced. The associations were similar among the oldest-old aged 80 or older with one exception for the case of IADL independence.

CONCLUSIONS

Self-perceived uselessness is negatively associated with successful aging among Chinese older adults as well as among the oldest-old. Our findings could be informative for China in the development of public health programs that aim to improve self-perceptions about aging and promote successful aging.

Associations of Successful Aging With Socioeconomic Position Across the Life-Course: The West of Scotland Twenty-07 Prospective Cohort Study

Objective: The aim of this study is to investigate how socioeconomic position (SEP) is associated with multidimensional measures of successful aging (SA), and how this varies and accumulates across the life-course. Method: Using data from 1,733 Scottish men and women from two cohorts aged around 57 and 76, respectively, we explored associations of SA, based on the Rowe–Kahn model, with 10 measures of SEP measured in childhood and, distally and proximally, in adulthood. Results: Individual SEP associations with SA score were generally consistent across different indicators and life stages: Respondents with the most versus least favorable SEP had two additional positive SA dimensions. There was also a strong association between SA and cumulative SEP based on all 10 measures combined; respondents with the most versus least favorable lifelong SEP had four additional positive SA dimensions. Conclusion: SEP advantages/disadvantages act and accumulate across the life-course, resulting in widening socioeconomic inequalities in SA in later life.

Is Parental Longevity Associated With the Cardiovascular Risk and the Successful Aging of Their Offspring? Results From the Multinational MEDIS Study

The aim of the present study was to evaluate the role of parental longevity and parental cardiovascular disease (CVD) history in CVD risk and successful aging of a random sample of older adults living in the Mediterranean basin and who participated in the MEDiterranean Islands (MEDIS) study. During 2005 to 2011, 2663 elders were voluntarily enrolled. A multidimensional successful aging index consisting of 10 components was used. Paternal and maternal longevity was defined as those older participants of whom both parents lived above the age of 90. The burden of CVD-related factors (CVD-RFs) was calculated as the total score of 4 major CVD-RFs (range 0-4). After adjustment, parental longevity was inversely associated with the burden of CVD-RFs ( P = .04). Moreover, parental longevity was positively associated with the older adults' successful aging score (β-coefficient [95% confidence interval]: .38 [0.06-0.71]). Parent's long living was revealed as an important factor for successful aging and for reduced CVD risk, suggesting that further research is needed in the genetic predisposition of longevity.

Successful aging at 100 years: the relevance of subjectivity and psychological resources

BACKGROUND

Very old individuals seem to present an admirable capacity to overcome adversities and adapt to the challenges of advanced age. However, studies focusing successful pattern of centenarians found that they may easily fail to be categorized as successful agers when objective criteria are applied. The present study examines if centenarians can be considered successful agers. Following Rowe and Kahn's successful aging model, the primary goal was to clarify whether centenarians are able to be successful agers according to objective and subjective criteria of no major disease and disability, high cognitive and physical functioning and engagement with life. The second goal was to investigate whether socio-demographic factors, psychological, social, and economic resources are related to objective and subjective successful aging profiles.

METHODS

We examined different profiles of successful aging in a high selected sample of individuals aged 100 and more years old from the population-based Oporto Centenarian Study.

RESULTS

Main findings reveal that centenarians do not represent the prototype of successful aging, but self-ratings demonstrate that many of them feel successful, despite not being objectively considered as so. Those who were considered successful agers presented higher values of self-efficacy, hope, and purpose in life, as well as few difficulties in covering financial expenses.

CONCLUSIONS

As a basis for strengthening the existing model, the value of subjectivity should be explored and psychological resources promoted in interventions to foster positive adaptation in very old age.

Validation of an a priori, index model of successful aging in a population-based cohort study: the successful aging index

BACKGROUND

Many definitions of successful aging (SA) exist in the absence of an established consensus definition. There are few examples of a priori application of SA models in real world contexts using external validation procedures. The current study aims to establish the predictive validity of an a priori, continuous model of SA with respect to service utilization.

METHODS

Individuals (n = 740; 64.2% female) aged 65 years and over (mean 75.9; SD 6.2), randomly selected from general practitioner registries in five sites across the United Kingdom included in the second and third combined screen and assessment waves of the Medical Research Council Cognitive Function and Aging Study (MRC CFAS; a longitudinal population-based cohort study) comprised the baseline and two-year follow-up in the current study. A Successful Aging Index (SAI) was created using items identified by systematic reviews of operational definitions and lay perspectives of SA, capturing physiological and psychosocial components. Demographic data and SAI components were collected at baseline. Outcome measures, i.e. health service use, informal care use, and functional service, were captured at two years follow-up.

RESULTS

Logistic regression revealed significant relationships between the SAI and six of eight service use outcomes in models adjusted for age, sex, education, and socio-economic status. Analysis of the area under the receiver operating characteristic (ROC) curve demonstrated sufficient predictive capabilities for all models, (range 0.65-0.86).

CONCLUSIONS

The SAI demonstrated a strong association, and predictive accuracy, with respect to service use, providing preliminary support for the practical utility and usefulness of this measure.

Predicting Successful Aging at One Hundred Years of Age

Objective:

The present study is based upon a multidimensional model of successful aging. It aims to identify subgroups of centenarians sharing communalities in successful aging profiles, and determine the role of sociodemographic factors and psychological, social, and economic resources on successful aging.

Methods:

A total of 80 centenarians were face-to-face interviewed. A cluster analysis was performed to identify distinct groups of successful aging, and logistic regression models were performed considering the cluster membership as dependent covariate.

Results:

Two distinct clusters were grouped, with 40 centenarians in each, one of them presenting better results in all domains. Male sex and better income adequacy were the best predictors of successful aging.

Conclusion:

Results help to identity different patterns of successful aging and provide greater clarity regarding its correlates, increasing current understanding of its modifiable aspects.
