From Successful Ageing to Ageing Well: A narrative review.

Since the term 'successful ageing' was coined, diverse models and theories conceptualising what it means to age successfully have been proposed. The current article outlines evidence suggesting that the use of 'success' in conjunction with 'ageing' is contentious, and thus 'ageing well' is recommended as an alternative term. This article also highlights the lack of consistency in approaches to successful ageing, and argues for a more inclusive conceptualisation of ageing well. To achieve this, the current article summarises the fundamental characteristics of several popular models of ageing successfully, demonstrating the unique contributions of each and highlighting recurring themes. The most common themes in existing models of successful ageing include the importance of engaging in social relationships, good cognitive and physical functioning, the avoidance of disease and disability, and resilience. Although commonalities exist, a consensus regarding an accepted definition of successful ageing is yet to be reached. To illustrate the need for consensus, policy approaches to support ageing populations by several governments are compared, highlighting the need for researchers to provide clearer guidance to policy makers. In addition, not all existing models are sensitive to the diversity of the ageing population, further emphasising the need to reconsider what it means to age well. The development of a consensus understanding of ageing well will improve the ability of researchers, as well as policymakers and client-facing workers, to effectively target areas that contribute to, and improve, individuals' ability to age well.

Pet ownership and psychosocial outcomes among the oldest old in Germany during the Covid-19 pandemic. Findings based on the nationally representative "Old Age in Germany (D80+)".

OBJECTIVES: To examine the association between pet ownership and psychosocial outcomes among the oldest old in Germany during the Covid-19 pandemic. METHODS/DESIGN: Data from the "Old Age in Germany (D80+)" study were used, a large, nationwide representative study covering both individuals living at home and individuals in nursing homes aged 80 years and above (n = 2867 individuals). The telephone interviews were conducted from May to October 2021. Established tools (e.g., "Short Form of the Depression in Old Age Scale", DIA-S4) were used to quantify the outcomes. Five groups were generated: (1) no pet ownership, (2) having at least one dog (but no other pets), (3) having at least one cat (but no other pets), (4) having at least one other pet (but neither dogs nor cats), (5) having at least two different types of pets (in any combination). RESULTS: Multiple linear regressions showed that compared to individuals without a pet, individuals having at least one dog had significantly lower loneliness levels (ß = -0.21, p < 0.01). In the fully-adjusted models, other forms of pet ownership were not significantly associated with the outcomes examined. CONCLUSION: Particularly living with a dog was associated with lower loneliness among the oldest old people in Germany. If living with a dog is in line with the preferences and attitudes of the very old, this could be a strategy for reducing loneliness in this age group.

Ageing well with a lifelong disability: A scoping review.

BACKGROUND AND OBJECTIVES: Existing literature highlights notable health and social inequalities for people ageing with a lifelong disability and the need for research to better understand how we can support this group to age well. This scoping review mapped existing literature related to 'ageing well' in people with lifelong disabilities. RESEARCH DESIGN AND METHODS: Five scientific databases and grey literature sources were searched for studies related to 'ageing well' and 'lifelong disability' (defined as a disability that a person had lived with since birth or early childhood). RESULTS: We identified 81 studies that discussed ageing well with a lifelong disability, with most (70%) focusing on intellectual disabilities. Two themes captured existing research on ageing well with a lifelong disability: 1.) Framing ageing well with a lifelong disability, which included the ways that people with lifelong disability, their supporters and existing research frame ageing well for this group and 2.) Supporting people to age well with a lifelong disability, which involves the micro, meso and macro-level factors where research suggests interventions to facilitate ageing well could be situated. DISCUSSION AND IMPLICATIONS: This synthesis highlights how ageing well is currently framed in the literature and where interventions to improve ageing well in this group could be situated. Literature highlights the importance of considering multi-level interventions to improve ageing well. Evidence gaps include the lack of research conducted with groups other than those with intellectual disabilities and the need for more research examining ageing well interventions.

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.

Successful ageing is associated with falls among older adults in India: a large population based across-sectional study based on LASI.

BACKGROUND: Falls are common in the elderly and can lead to adverse consequences, like injuries, hospitalization, disability even mortality. Successful ageing emerged in sight to assess physical, psychological and social status of older adults. This study is conducted to explore the association between them in a large Indian community-dwelling population. METHODS: Data were based on the wave 1 survey of the Longitudinal Ageing Study in India (LASI). People aged 60 and above with complete information were included. The elderly met five standards including absence of chronic diseases, freedom from disability, high cognitive ability, free from depressive symptoms and active social engagement, were classified into successful agers. The assessment of falls, fall-related injuries and multiple falls depended on interview. Multivariate logistic regression was conducted to find the associations between falls, fall-injury, multiple falls and successful ageing after adjusting both socio-demographic and biological covariates. The log-likelihood ratio test was calculated interactions in subgroups. RESULTS: 31,345 participants in LASI were finally included in our study. Of them, 20.25% reported fall, and 25% were classified into successful agers. After full adjustment, successful ageing was negatively associated with falls (OR 0.70; 95%CI 0.65-0.76) and multiple falls (OR 0.70; 95%CI 0.63-0.78). And the association did not show the significance in older adults with fall-related injuries (OR 0.86; 95%CI 0.72-1.04). CONCLUSIONS: Successful ageing was negatively associated with falls and multiple falls, but not fall-related injuries in older people in India. Future studies are demanded to explore the causal relationship and to reveal the underlying mechanism.

Operationalisation of Successful Ageing in the Oral Health Context: A Citation Analysis.

OBJECTIVES: The rapidly ageing world has placed considerable demands on health and social care. To address this, the World Health Organization (WHO) and United Nations (UN) have declared action for this decade (2021-2030) to promote healthy ageing. Operationalisation of successful ageing in the oral health context in terms of its dimensions and their interconnectedness was determined. METHODS: A citation analysis was conducted following a scoping review to determine oral health's relationship with 5 key dimensions of successful ageing. This included examining the occurrence and co-occurrence amongst dimensions and over time. Specific consideration of citations by country, journal type, and authors through overlay visualisation was performed to map their interconnectedness. RESULTS: The scoping review identified 263 publications covering 1730 specific terms. There was a growing interest in successful ageing in the oral health context, mostly in the past decade (2010 onwards; 65.8%, 173 publications). The dimension of key consideration was "health and ADLs" (activities of daily living); this dimension appeared in 97.3% of publications (n = 256) and was found earliest to emerge, with the greatest link strengths compared to other dimensions. Country-level variations in citation data were observed, and there was good citation interconnectedness between them. Key oracles for dissemination have been medical rather than dental-specific journals. Amongst authors, there was considerable interconnectedness in the field. CONCLUSIONS: Findings highlight how successful ageing in the oral health context has been studied, with implications for addressing the significance of oral health to older peoples' lives in line with the WHO and UN's agenda. Citation analyses identified the "known unknowns" area for further consideration, and these findings have the potential to inform how dental research may best move forward with the successful ageing agenda to bring about translational impact.

Developing an intelligent prediction system for successful aging based on artificial neural networks.

Background: Due to the growing number of disabilities in elderly, Attention to this period of life is essential to be considered. Few studies focused on the physical, mental, disabilities, and disorders affecting the quality of life in elderly people. SA1 is related to various factors influencing the elderly's life. So, the objective of the current study is to build an intelligent system for SA prediction through ANN2 algorithms to investigate better all factors affecting the elderly life and promote them. Methods: This study was performed on 1156 SA and non-SA cases. We applied statistical feature reduction method to obtain the best factors predicting the SA. Two models of ANNs with 5, 10, 15, and 20 neurons in hidden layers were used for model construction. Finally, the best ANN configuration was obtained for predicting the SA using sensitivity, specificity, accuracy, and cross-entropy loss function. Results: The study showed that 25 factors correlated with SA at the statistical level of P < 0.05. Assessing all ANN structures resulted in FF-BP3 algorithm having the configuration of 25-15-1 with accuracy-train of 0.92, accuracy-test of 0.86, and accuracy-validation of 0.87 gaining the best performance over other ANN algorithms. Conclusions: Developing the CDSS for predicting SA has crucial role to effectively inform geriatrics and health care policymakers decision making.

The impact of sustainable diets οn cognitive function in an ageing society: A mini-review.

The increasing number of older people raises important health concerns because, in part, of the associated cognitive and functional impairment. The United Nations is taking action with its Decade of Healthy Ageing (2021-2030) campaign, by promoting Sustainable Development Goals and shifting our focus towards more sustainable diets. In this mini-review, sustainable dietary patterns are evaluated, with a focus on healthy plant-based diets, the Mediterranean diet, the Dietary Approaches to Stop Hypertension (DASH) diet, and the Mediterranean-DASH Intervention for Neurodegenerative Delay diet. The review analyzes and describes whether older people's cognitive performance can benefit from the adoption of these sustainable diets. The results of primary studies indicate that the Mediterranean diet and healthy plant-based diets can prevent cognitive impairment by improving cognitive function, language and memory. Plant-based dietary patterns with incorporated Mediterranean foods (high consumption of fruit, vegetables, and fish) are associated with delayed cognitive ageing. Additionally, adherence to the Mediterranean-DASH Intervention for Neurodegenerative Delay diet is associated with improved cognitive resilience and lower risk of dementia after 16 years of follow-up. Although consumption of red meat and elevated body mass index are both associated with cognitive dysfunction, some studies have had contradictory findings. Concerns exist regarding the development of chronic diseases, cognitive and functional impairment, as well as disability as age advances. Thus, the policies of the United Nations should ensure healthy ageing for all older individuals. Nonetheless, more research is required to evaluate older people's willingness and readiness to adopt a more sustainable way of eating.

"My wife made me": motivations for body and beauty work among older Korean and Chinese migrant adults in Australia.

This article examines how older Korean and Chinese migrants living in Perth, Australia, engage in various beauty, grooming and fitness practices to negotiate "successful ageing" in transnational contexts. Drawing on semi-structured interviews with 30 men and women aged between 60 and 89, we examine what social meanings are attached to these practices, and how the transnational context of living in Australia has influenced the participants' perceptions of ageing and presentation of self in later life. Migration in later life is often considered in relation to the 'host' countries values and social practices, which can make it difficult for individuals to settle and feel a sense of belonging especially in later life. In this article, we will illustrate how gender, class, and cultural dispositions intersect and link with possibilities for defining and redefining successful ageing in migrant contexts. This study illustrates how successful ageing emerges as a malleable concept that draws on ideas of an ideal ageing body from the cultural values of the 'home' country, rather than the 'host' country. The findings illustrate how in everyday lived experience, the transnational habitus does not always necessarily result in a 'divided habitus' where the values of the 'home' country and that of the 'host' country are in conflict - even when the migration experience is relatively recent. Quite the contrary, the way the participants utilise everyday beauty, fitness and grooming practices to maintain a future-focused self in the context of 'home' country's age-appropriate body ideals to perform signifiers of 'successful migrant living' point to the positive aspects that appearance management can have on an individual in later life, particularly in migrant contexts.

Identifying and predicting physical limitation and cognitive decline trajectory group of older adults in China: A data-driven machine learning analysis.

OBJECTIVE: This study aimed to utilize data-driven machine learning methods to identify and predict potential physical and cognitive function trajectory groups of older adults and determine their crucial factors for promoting active ageing in China. METHODS: Longitudinal data on 3026 older adults from the Chinese Longitudinal Healthy Longevity and Happy Family Survey was used to identify potential physical and cognitive function trajectory groups using a group-based multi-trajectory model (GBMTM). Predictors were selected from sociodemographic characteristics, lifestyle factors, and physical and mental conditions. The trajectory groups were predicted using data-driven machine learning models and dynamic nomogram. Model performance was evaluated by area under the receiver operating characteristics curve (AUROC), area under the precision-recall curve (PRAUC), and confusion matrix. RESULTS: Two physical and cognitive function trajectory groups were determined, including a trajectory group with physical limitation and cognitive decline (14.18 %) and a normal trajectory group (85.82 %). Logistic regression performed well in predicting trajectory groups (AUROC = 0.881, PRAUC = 0.649). Older adults with lower baseline score of activities of daily living, older age, less frequent housework, and fewer actual teeth were more likely to experience physical limitation and cognitive decline trajectory group. LIMITATION: This study didn't carry out external validation. CONCLUSIONS: This study shows that GBMTM and machine learning models effectively identify and predict physical limitation and cognitive decline trajectory group. The identified predictors might be essential for developing targeted interventions to promote healthy ageing.

Social network type contributes to purpose in life among older people, mediated by social support.

A sense of Purpose in Life is an important aspect of ageing well which is related to older adult's social relationships. Social network types and the different sources of support they provide are theorized here as a pathway to maintaining a sense of purpose as we age. The study utilized a population sample from the 2016 and 2020 NZ Health, Work, and Retirement (NZHWR) longitudinal survey waves; N = 2869 (mean age of 65.82 years (SD = 6.40). A structural equation model investigated the relationship between Social Network Type and Purpose in Life and the mediating role of Social Support. The final model had a good fit to the data and explained 33.7% of the variance in Purpose in Life. Private, Self-Contained and Family Dependent network types (2016) were negatively related to Purpose in Life 4 years later (2020). Support from sense of Attachment, Reassurance of Worth, Reliable Alliance and Social Integration played a mediating role between Social Network type and Purpose in Life. These findings highlight the importance of social networks in maintaining a sense of purpose among older adults and highlight pathways for the types of networks, and kinds of social support they offer, which contribute to a sense of purpose in life. They underscore the importance of social support for the well-being of older adults and highlight the need to consider the quality and type of social networks and support they provide, when designing interventions to enhance well-being.

Impact of information technology supported serious leisure gardening on the wellbeing of older adults: The Turntable project.

OBJECTIVE: The study presented in this paper aimed to assess the effect of an Information Technology enabled community gardening program for older adults, developed by an international consortium. METHODS: We have executed a quantitative, pre- and post-test field trial with older adult volunteers to test the proposed programme in two European countries, Italy and Belgium (n=98). We used standardized and ad hoc questionnaires to measure changes in the volunteers' mental and psychological state during the trial. The statistical data analysis sought for differences in the pre- and post-test values of the key scores related to the perceived quality of life and benefits of gardening via paired-samples t-tests, and also tried to identify the important factors of significant changes via logistic regression. RESULTS: We found significant improvements in the perceived benefits of gardening and also in the scores computed from the WHO Quality of Life instruments, especially in the social sub-domains. The improvements were associated with the country, age, marital state and education of the volunteers. Higher age or being widow, divorced or single increased the odds of a significant improvement in the scores in more than one sub-domains. CONCLUSION: Though the two trial settings were different in some aspects, the observed significant improvements generally confirmed the positive effects of gardening concerning the perceived quality of life and benefits of gardening.

The reliability and suitability of strength assessments in frail and pre-frail older adults: recommendations for strength testing in older populations.

BACKGROUND: Lifelong strength is fundamental to physical function, health, and quality of life. Reliable appropriate strength assessment measures for older adults play an important role in effective evaluation of baseline ability and exercise prescription to counter disease and disuse. This study aimed to investigate the within-session reliability of maximal isometric knee extension and flexion, hip abduction and adduction, and handgrip strength measures in frail and pre-frail older adults. METHOD: The study was conducted at a residential care home in Birmingham, UK. All care home residents aged ≥ 65 years; pre-frail or frail according to the Fried Frailty phenotype criteria; able to speak and read English; not currently involved in any other clinical trial; without severe sensory impairments; and with a predicted life expectancy greater than the trial length were eligible. Maximal isometric lower limb testing was performed using specialised resistance training equipment and a portable measurement device, and grip strength was assessed using a portable dynamometer. All eligible participants attended a single testing session and performed three trials per measure. Peak force measures were obtained for analysis. Within-session reliability for each measure was calculated from repeated-measures analysis of variance, intraclass correlation coefficients (ICC), and coefficients of variation (CV) with 95% confidence intervals. RESULTS: Eleven frail and eleven pre-frail older adults participated in the study. Within-session absolute and relative measures were found to be reliable with the highest overall repeatability indicated between trial 2 and trial 3 for knee extension, hip abduction, and handgrip (CV ≤ 4.65%, ICC ≥ 0.96) with variation evident across all measures, except knee extension, from trial 1 to 2. CONCLUSIONS: Overall, maximal isometric strength in frail and pre-frail older adults with no previous testing experience can be measured with good to high reliability within their first testing session. An initial two familiarisation trials followed by two measurement trials is recommended to achieve the highest level of overall repeatability. TRIAL REGISTRATION: The trial was registered with ClinicalTrials.gov: NCT03141879 on 05/05/2017.

Defining exceptional cognition in older adults: A systematic review of cognitive super-ageing.

OBJECTIVE: A consistent approach to defining cognitive super-ageing is needed to increase the value of research insights that may be gained from studying this population including ageing well and preventing and treating neurodegenerative conditions. This review aims to evaluate the existing definitions of 'super-ageing' with a focus on cognition. METHODS: A systematic literature search was conducted across PubMed, Embase, Web of Science, Scopus, PsycINFO and Google Scholar from inception to 24 July 2023. RESULTS: Of 44 English language studies that defined super-ageing from a cognitive perspective in older adults (60-97 years), most (n = 33) were based on preserved verbal episodic memory performance comparable to that of younger adult in age range 16-65 years. Eleven studies defined super-agers as the top cognitive performers for their age group based upon standard deviations or percentiles above the population mean. Only nine studies included longitudinal cognitive performance in their definitions. CONCLUSIONS: Equivalent cognitive abilities to younger adults, exceptional cognition for age and a lack of cognitive deterioration over time are all meaningful constructs and may provide different insights into cognitive ageing. Using these criteria in combination or individually to define super-agers, with a clear rationale for which elements have been selected, could be fit for purpose depending on the research question. However, major discrepancies including the age range of super-agers and comparator groups and the choice of cognitive domains assessed should be addressed to reach some consensus in the field.

Mismatch Between Older Persons' Generative Concern and Internalized Generative Capacities: Leveraging on Generative Ambivalence to Enhance Intergenerational Cohesion.

Studies have shown how generativity, the concern for establishing and guiding the next generation and safeguarding its wellbeing, functions as an intergenerational conduit, bridging the developmental stages of older individuals with those younger. Yet, applications of generativity, as a means to bridge generational gaps within rapid social change, remain underexplored in the intergenerational field. Using Singapore as a case study, and through focus group discussions with 103 older persons, this paper examines how older Singaporeans express their generative concern and internalize their generative capacities across different social settings and rapid socioeconomic transformation. Mismatch between older Singaporeans' generative concern and capacity contributes to ambivalence - mixed feelings about guiding younger generations - which emerges out of older Singaporeans' struggles with cultural change prompted by economic progress, as well as concerns about their place and value in a technologically advanced global city-state. The concept of generative ambivalence can add value to policy perspectives on intergenerational cohesion, as it considers people's attempts to forge commonalities and mutual reciprocity despite differences (e.g. gender, age, race, skills), as well as highlights intergenerational complexities beyond superficial binaries. Policies aimed at bringing generations together must be intentional in creating opportunity structures that go beyond categorical differences, where multiple generations can thrive interdependently.

New measure of functional tooth loss for successful Oral ageing: a cross-sectional study.

BACKGROUND: This cross-sectional study evaluated the impacts of functional tooth loss on oral health-related quality of life (OHRQoL) among elderly people compared with the impacts of several common indicators of oral health. Additionally, the cut-off of functional tooth loss needed for a better OHRQoL was investigated to establish a new measure for successful oral ageing. METHODS: Data from people aged 65-74 were extracted from the Fourth National Oral Health Survey in Sichuan, China. Functional tooth loss was defined as both natural tooth loss and nonfunctional teeth, such as third molars, residual roots, and removable dentures. The cut-offs of tooth loss were first identified as 12, based on the previous definition of functional dentition (≥20 natural teeth except the third molars), and 14, 16, or 18 for further investigation. OHRQoL was evaluated by the standardized Geriatric Oral Health Assessment Index (sGOHAI) score. Logistic regression was performed to estimate the impacts on OHRQoL. Additionally, subgroup analyses were conducted using the stratified chi-square test to explore the effect of functional tooth loss at each position. RESULTS: The mean GOHAI score of the 744 participants was 48.25 ± 7.62. Elderly people who had lost ≤12 functional teeth had greater odds of reporting a higher sGOHAI score than those who had lost more functional teeth (odds ratio (OR) 1.49, 95% confidence interval (CI) 1.05-2.11). No significant difference in the sGOHAI score was detected between people who had lost 13-16 functional teeth and those who had lost ≤12 functional teeth (0.61, 0.35-1.07). The loss of second premolars and first and second molars had great impacts on the sGOHAI score when ≤12 or ≤ 16 functional teeth had been lost. CONCLUSIONS: Compared with natural tooth loss, functional dentition and occluding pairs, functional tooth loss can be a better indicator of OHRQoL in the elderly population. Sixteen remaining functional teeth seem to be sufficient to maintain good OHRQoL and successful oral ageing despite that number being previously acknowledged as ≥20 teeth.

Leaving no one behind: successful ageing at the intersection of ageism and ableism.

BACKGROUND: The concept of 'successful ageing' has been a prominent focus within the field of gerontology for several decades. However, despite the widespread attention paid to this concept, its intersectional implications have not been fully explored yet. This paper aims to address this gap by analyzing the potential ageist and ableist biases in the discourse of successful ageing through an intersectional lens. METHOD: A critical feminist perspective is taken to examine the sensitivity of the discourse of successful ageing to diversity in societies. The paper analyzes how ageist and ableist biases can manifest in the ways we conceptualize ageing, drawing on examples in the context of mental health. RESULTS: We argue that the conventional approach to successful ageing is limited in its ability to account for the experiences of people who have faced intersectional discrimination throughout their lives. Drawing on examples in the context of mental health, we explore among others the link between depression and disabilities. Furthermore, we shed light on the negative impact of ageist and ableist attitudes concerning the diagnosis and treatment of dementia. DISCUSSION: We demonstrate how diversity is often overlooked in discussions of ageing well, and how ageist and ableist biases can manifest in the ways we conceptualize ageing. We argue that focusing solely on the health status as a means of achieving success fails to adequately counter ageism for all people. We further emphasize the role of structural factors, such as ageist attitudes, in shaping the experience of ageing and exacerbating health inequalities. CONCLUSION: Overall, our findings emphasize the need for a more nuanced and inclusive understanding of ageing and therefore an intersectional approach to conceptions of ageing well that recognizes and addresses the biases and limitations of current discourses. Thereby, this paper offers valuable insights into the complex intersections between age and disabilities from a bioethical perspective, highlighting the need for a more inclusive and intersectional approach to ageing.

Active and productive ageing in India: evidence from the time use pattern of ageing adults.

BACKGROUND: With the increasing proportion of older adults in India, it becomes essential to get an insight into the various influencing factors of successful ageing. However, the literature on successful ageing is minuscule in the Indian context. The present study attempted to understand successful ageing in terms of active and productive ageing by exploring their determining factors. METHODS: The data were extracted from the Longitudinal Ageing Study in India (LASI) Wave-1 (2017-2018). We utilized self-reported time use information from the experimental module of the LASI. A total of 7837 ageing adults were included in the study. We employed descriptive statistics, bivariate analysis and a multinominal logistic regression model to examine the prevalence and the determinants of active and productive ageing. RESULTS: The prevalence of inactive ageing was higher among the Indian ageing population (57.47%), followed by active ageing (29.59%) and productive ageing (12.94%). Poor sleep quality and the prevalence of morbidity and disability limited the ageing population from attaining active and productive ageing. Engagement in physical activity was significantly associated with active and productive ageing (ß = 0.83, 99% CI: -0.72-0.94 and ß = 0.82, 99% CI: 0.66-0.98), respectively. Rural ageing adults were more likely to attain active ageing and less likely to attain productive ageing. CONCLUSION: Engagement in physical activities among the ageing population shall be promoted to attain active and productive ageing. Since the rural ageing population were less likely to attain productive ageing than their urban counterparts, opportunities to participate in more formal economic activities in rural areas could be promoted for the wellbeing of the second demographic dividend.

Multiple Roads to Success: A Latent Class Analysis on Successful Ageing Among Hong Kong Near-Centenarians and Centenarians (NCC).

Notwithstanding the oldest-old cohort being the fastest-growing population in most ageing societies, characterizing successful ageing in adults of advanced age, such as nonagenarians and centenarians, remains challenging. This study investigated the successful ageing subphenotypes using the data from Hong Kong Centenarian Study 2. Between April 2021 and September 2022, 146 family caregivers of community-dwelling older adults aged 95 or above were interviewed by phone. Latent class analysis identified three classes-Overall Frail (46.6%) with poor mobility, cognitive and functional health, Nonambulant (37.0%) but good functional health, and Robust (16.4%) with overall good health-from 11 indicators based on caregivers' reports. Although we found a low prevalence of fulfillment of all indicators of successful ageing, our findings will help care professionals appreciate the heterogeneity underlying partial successful ageing in this vulnerable cohort for segmented and targeted healthy longevity interventions.
