In this "Decade of Healthy Ageing," the integration of resilience into the healthy aging discourse becomes paramount, particularly in the context of indigenous communities grappling with the enduring effects of historical oppression, persistent poverty, and health disparities in their aging journey. Employing a phenomenological lens, this study seeks to derive the resilient characteristics exhibited by the Attappadi indigenous older adults of Kerala, aiming to explore the role of resilience in their pursuit of healthy aging. In-depth phenomenological interviews ( n  = 34), observation, and document analysis have revealed four key themes: A life course marked by adversities, Embracing the unyielding strength within, Personal resilience catalysts, and Extrinsic resilience catalysts. The participants exhibited a reasonably well-functioning collective, given their persistent adversities in their life course. Narratives illuminated a notable connection between the presence of resilience characteristics and the overall functioning of older adults. From a social work standpoint on resilience, this article underscores the vital interplay between individual agency and environmental factors in addressing adversity. The article advocates culturally sensitive, asset-based strategies to strengthen indigenous older adults' intrinsic and extrinsic resilience to ensure that they are not left behind in the global pursuit of healthy aging.

The promotion of healthy aging has become a priority in most parts of the world and should be promoted at all ages. However, the baseline training of health and social professionals is currently not adequately tailored to these challenges. This paper reports the results of a Delphi study conducted to reach expert agreement about health and social professionals' competencies to promote healthy aging throughout the lifespan within the SIENHA project. Materials and methods: This study was developed following the CREDES standards. The initial version of the competence framework was based on the results of a scoping review and following the CanMEDS model. The expert panel consisted of a purposive sample of twenty-two experts in healthy aging with diverse academic and clinical backgrounds, fields and years of expertise from seven European countries. Agreement was reached after three rounds. The final framework consisted of a set of 18 key competencies and 80 enabling competencies distributed across six domains. The SIENHA competence framework for healthy aging may help students and educators enrich their learning and the academic content of their subjects and/or programs and incentivize innovation., (© 2024.

Background: Ageing is one of the most important challenges in our society. Evaluating how one is ageing is important in many aspects, from giving personalized recommendations to providing insight for long-term care eligibility. Machine learning can be utilized for that purpose, however, user reservations towards "black-box" predictions call for increased transparency and explainability of results. This study aimed to explore the potential of developing a machine learning-based healthy ageing scale that provides explainable results that could be trusted and understood by informal carers., Methods: In this study, we used data from 696 older adults collected via personal field interviews as part of independent research. Explanatory factor analysis was used to find candidate healthy ageing aspects. For visualization of key aspects, a web annotation application was developed. Key aspects were selected by gerontologists who later used web annotation applications to evaluate healthy ageing for each older adult on a Likert scale. Logistic Regression, Decision Tree Classifier, Random Forest, KNN, SVM and XGBoost were used for multi-classification machine learning. AUC OvO, AUC OvR, F1, Precision and Recall were used for evaluation. Finally, SHAP was applied to best model predictions to make them explainable., Results: The experimental results show that human annotations of healthy ageing could be modelled using machine learning where among several algorithms XGBoost showed superior performance. The use of XGBoost resulted in 0.92 macro-averaged AuC OvO and 0.76 macro-averaged F1. SHAP was applied to generate local explanations for predictions and shows how each feature is influencing the prediction., Conclusion: The resulting explainable predictions make a step toward practical scale implementation into decision support systems. The development of such a decision support system that would incorporate an explainable model could reduce user reluctance towards the utilization of AI in healthcare and provide explainable and trusted insights to informal carers or healthcare providers as a basis to shape tangible actions for improving ageing. Furthermore, the cooperation with gerontology specialists throughout the process also indicates expert knowledge as integrated into the model., (© 2024. The Author(s).)

Objective: Several research gaps affect the improvement of care for healthy ageing. Their identification is crucial to developing a specific research prioritisation agenda supporting progress at the micro (clinical), meso (service delivery) and macro (system) levels. To achieve this, a scoping review was carried out to describe the most significant gaps impeding the improvement of care for healthy ageing., Design: A scoping review of the literature was conducted according to the Joanna Briggs Institute methodology. The selected articles were analysed to identify topics or areas essential for improving care for healthy ageing but requiring further support from research., Eligibility Criteria: Every type of scientific article, except for randomised controlled trials, was considered of potential interest without restrictions on publication date, type of publication and methodology., Information Sources: A systematic search (last search: 6 December 2023) was conducted using PubMed, MEDLINE and Scopus., Results: Overall, 1558 articles were retrieved from the literature. Of these, 310 were finally retained for this work. A total of 1195 research gaps were identified (average: 3.85 per article) and clustered into the 13 primary areas: ageing, care approach, caregivers, health economics, health, interventions, policies, research, settings, training, technology, specific populations and understanding the older person. In particular, research for improving the person-centred approach (n=38), better considering cultural diversities (n=27), implementing integrated care (n=25) and ensuring access to care (n=25) were the most prevalent priorities reported in the literature., Conclusions: A wide range of factors spanning multiple disciplines, from clinical to policy levels, require special consideration, exploration and resolution. The findings of this scoping review represent an essential step in identifying gaps for developing a research prioritisation agenda to improve care for healthy ageing., Competing Interests: Competing interests: None declared., (© World Health Organization 2024.

Background: Diet and exercise interventions have been associated with improved body composition and physical fitness. However, evidence regarding their combined effects in older adults is scarce. This study aimed to investigate the impact of a combined 12-week Mediterranean diet-based sustainable healthy diet (SHD) and multicomponent training (MT) intervention on body composition, anthropometry, and physical fitness in older adults., Methods: Diet intervention groups received a weekly SHD food supply and four sessions, including a SHD culinary practical workshop. The exercise program included MT 50 min group session, three times a week, on non-consecutive days. Body composition and physical fitness variables were assessed through dual X-ray absorptiometry, anthropometric measurements, and senior fitness tests. Repeated measures ANOVA, with terms for group, time, and interaction, was performed., Results: Our results showed that a combined intervention significantly lowered BMI and total fat. Also, significant differences between assessments in all physical fitness tests, except for aerobic endurance, were observed. Adjusted models show significant differences in BMI ( p = 0.049) and WHR ( p = 0.037) between groups and in total fat ( p = 0.030) for the interaction term. Body strength ( p < 0.001), balance tests ( p < 0.001), and aerobic endurance ( p = 0.005) had significant differences amongst groups. Considering the interaction term, differences were observed for upper body strength ( p = 0.046) and flexibility tests ( p = 0.004 sit and reach, p = 0.048 back scratch)., Conclusions: Our intervention study demonstrates the potential of implementing healthy lifestyle and sustainable models to promote healthy and active aging.

A clinically useful characterization of the cognitive aging process requires the development of valid and robust behavioral tests, with an emphasis on explaining and understanding typical inter-individual variability in cognition. Here, using a dataset that includes behavioral scores collected with the National Institute of Health Toolbox Cognition Battery (NIHTB-CB) and other auxiliary tests, we examined (1) the differences between young and old adults across different cognitive domains, (2) the strength of across-subject correlations in behavioral test scores, (3) the consistency of low-dimensional behavioral representations across age using factor analysis, and (4) the accuracy of behavioral scores in predicting participants' age. Our results revealed that (1) elderly females had better verbal episodic memory scores than elderly males, (2) across-subject correlations between behavioral tests varied with age group, (3) although a three-factor model explained the behavioral data in both age groups, some tasks loaded to different factors between the two groups, and (4) age-performance relationship (i.e. a regression model linking age to cognitive scores) in one group cannot be extrapolated to predict age in the other group, indicating an inconsistency in age-performance relationships across groups. These findings suggest that executive function tests might tap into different cognitive processes in different age groups, which might ultimately suggest that a statistically significant between-group difference in test performance might not always reflect differences in the same underlying cognitive processes. Overall, this study calls for more caution when interpreting age-related differences and similarities between age groups with different cognitive abilities even when the same tests are used., (© 2024.

Objective: This study aimed to evaluate the association between the Yokohama Walking Point Program, which promotes walking through feedback on step counts and incentives, and the extension of healthy life expectancy., Methods: A total of 4298 individuals aged over 65 years who responded to the 2013 and 2016 surveys and who were not certified as needing long-term care in 2016 were included in this study. The participants were categorized into "non-participation," "participation without uploading," and "participation with uploading" groups based on their involvement and uploading of pedometer data. The objective variable was the occurrence of long-term care certification and deaths over the subsequent four years. A modified Poisson regression model was applied, adjusting for 15 variables before project initiation., Results: A total of 440 participants (10.2 %) were included in the "participation with uploading" group and 206 (4.8 %) in the "participation without uploading" group. Compared with "non-participation," the risk ratio was 0.77 (95 % confidence interval (CI): 0.59-0.99) for "participation with uploading" and 1.02 (95 % CI: 0.75-1.38) for "participation without uploading". In the sensitivity analysis censoring death as an inapplicable outcome and considering functional decline, participation with uploading showed a risk ratio of 0.79 (95 % CI: 0.60-1.04) for the likelihood of functional decline., Conclusions: The use of pedometers and health point programs based on walking activity is associated with enhancing the health of older individuals participating in the program, representing a population-centric strategy targeting all citizens., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Mountain cultivated ginseng (MCG) is planted in mountain forests to simulate traditional wild ginseng; therefore, it has a greater pharmacological effect than cultivated ginseng (CG) in the garden; however, insufficient evidence confirms this theory. In light of the health-promoting and life-extending properties of ginseng, we analyzed the efficacy of MCG and CG. Initial observations revealed that the phytosterols content of MCG was higher than that of CG, with a positive correlation to the duration of growth. The distinction between phytosterols in MCG and in CG is predominately determined by the stigmasterol content using High-Performance Liquid Chromatography (HPLC). The lifespan of Drosophila melanogaster (fruit flies) that aged naturally was prolonged by phytosterols in MCG and CG and stigmasterols. Further, they prolonged healthy ageing as measured by progeny numbers, length of sleep, climbing distance, and survival following oxidative damage. The findings of behavioral observations revealed that phytosterols in MCG were more efficacious than in CG in promoting health maintenance and life extension; moreover, stigmasterol indicated that these effects were dose-dependent. Stigmasterols, phytosterols in MCG and CG have restored age-associated decreases in steroid hormone levels. Notably, molecular docking was predicted to promote stigmasterol's binding to the steroid hormone receptor ECR due to its similarity to steroid hormones. In addition, stigmasterols triggered the steroid hormone signaling pathway by increasing the activity of key genes Eip75B and Br in 20E signaling and Jhamt, HmGR, Met, and Kr-h1 in JH signaling. Phytosterols, as a natural product, regulated health and longevity as a dietary supplement similar to that of steroids, which supported the social requirements of healthy ageing., Competing Interests: Declaration of competing interest The authors have declared that no competing interests exist., (Copyright © 2024 The Authors.

Background: For older Latinos, some benefits of leisure-time physical activity (LTPA) include enhanced cognitive functioning, decreased loneliness, and reduced premature mortality. Despite LTPA benefits, adults ≥50 years are one of the most inactive age groups in the United States., Methods: This qualitative study aimed to add to the limited evidence of LTPA in older Latino adults by exploring the barriers and facilitators for fitness class uptake and park use. Guided by a Social-Ecological Model of Health and Social Determinants of Health theoretical and a phenomenological research design, qualitative research data were collected via 27 personal interviews with Latino adults using a semistructured interview guide. Participants were recruited using purposive sampling strategies in collaboration with community partners. Bicultural data collectors conducted the semistructured interviews over Zoom. Thematic analysis was performed using Dedoose, following an inductive and deductive approach., Results: The main barriers to fitness class attendance and park use were family and/or work commitments, perceived safety, and perceived discrimination. Conversely, the critical facilitators for participation were socialization into a group, social connectedness with group members, fitness instructor characteristics, and exercise history., Conclusions: Findings from this study hold important implications for the design of fitness programming and park-based recreation, including the need to increase the cultural diversity of recreation staff and culturally relevant programming. Future research is needed on time poverty related to family/work commitments and whether discriminatory practices at fitness centers, like ageism and race/ethnicity, influence physical activity behavior., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Omega-3 polyunsaturated fatty acids (ω-3 PUFAs, n-3 PUFAs), including eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA), are essential polyunsaturated fats primarily obtained from fatty fish and plant-based sources. Compelling evidence from preclinical and epidemiological studies consistently suggests beneficial effects of ω-3 PUFAs on bone health and healthy aging processes. However, clinical trials have yielded mixed results, with some failing to replicate these benefits seen in preclinical models. This contraindication is mainly due to challenges such as low bioavailability, potential adverse effects with higher doses, and susceptibility to oxidation of ω-3 fatty acids, hindering their clinical effectiveness. This review comprehensively discusses recent findings from a clinical perspective, along with preclinical and epidemiological studies, emphasizing the role of ω-3 PUFAs in promoting bone health and supporting healthy aging. Additionally, it explores strategies to improve ω-3 PUFA efficacy, including nanoparticle encapsulation and incorporation of specialized pro-resolving mediators (SPM) derived from DHA and EPA, to mitigate oxidation and enhance solubility, thereby improving therapeutic potential. By consolidating evidence from various studies, this review underscores current insights and future directions in leveraging ω-3 PUFAs for therapeutic applications., Competing Interests: The authors declare no conflicts of interest.

The population aging in the region is occurring under scenarios of inequality, raising concerns about how the increase in life expectancy is experienced and what factors affect the quality of life of older adults. This research quantified the differentials of healthy aging in Colombia in 2018 and its association with social indicators through a cross-sectional, descriptive, and correlational observational study. Healthy aging was quantified using the Disability-Free Life Expectancy (DFLE) indicator and later correlated with social indicators and subjected to a Multiple Factor Analysis (MFA). The results showed a healthy life expectancy of 71.5 years for women and 66.9 years for men, with a disability expectancy of 8.3 and 6.4 years, respectively. Negative associations emerged with health problems, disability, lack of medical care, illiteracy, school absenteeism, and poverty, while higher education levels and retirement showed positive associations. The factor analysis by area of residence highlighted urban areas as conducive to healthy aging. In conclusion, the accelerated aging of the Colombian population faces health disparities that policies must address by improving education, economic security, and health services, especially for women and rural areas.

Europe's ageing population increases the demand for housing solutions targeting older citizens' needs and preferences. Establishing age-friendly communities fostering social participation is essential for healthy ageing and various housing options with shared facilities prioritizing social contact have emerged. While involving older people in public service delivery is emphasized, studies on co-production with older people in building age-friendly communities remain limited. This study explores a co-production initiative between older citizens, a municipality and a real estate company in a newly established senior village focusing on organizational settings and physical facilities. A qualitative study inspired by the BIKVA methodology was conducted using focus group interviews with citizens, frontline staff, and management. Through reflexive thematic analysis, the physical environment, organizational setting and other factors influencing the co-production process were analysed. Citizens expressed satisfaction with the unique physical environment, the different activities and being involved in the co-production process on development and building up the senior village. However, the co-production initiative was influenced by the lack of frontline staff involvement, how the physical facilities were organized for building inclusive communities as well as the level of information provided to align expectations among stakeholders. Involving older citizens in the co-production of age-friendly community initiatives has the potential to take the identified challenges into account. To understand what constitutes an optimal environment for healthy ageing further research in collaboration with older citizens is needed., (© 2024. The Author(s).)

Background: This viewpoint paper reports the state of the art at a global level on research, practice and assessment, policies, and training in the clinical psychology of aging and, more specifically, in geropsychology. The main sources of information were as follows: (1) the most recent reviews of the literature available in the scientific literature; (2) the resources on the internet referable to professional and academic associations dealing with the topic; and (3) the laws, policy initiatives, and funded programs that are aimed at the diffusion and applications of mental health in aging., Methods: The present study aims to provide an updated and comprehensive memorandum highlighting the importance of prioritizing mental health in older adults. It seeks to promote health in general and disease prevention strategies, ensuring equitable access to mental health services integrated into primary care and designed for aging. This paper also aims to shed light on the slow development process and lack of consolidation in the adaptation of academic training at master's and doctoral levels in most developed countries, despite the long-declared importance of enhancing resources for the promotion of geropsychology., Results: The results of the present study are patchy. Although the importance of enhancing resources for the promotion of geropsychology has long been declared, the development process seems very slow, and the adaptation of academic training at master's and doctoral levels in most developed countries-those that, for demographic reasons and attitudes, should be more sensitive to the issue, does not yet seem to have consolidated., Conclusions: Collaboration among diverse professionals is crucial for providing integrated and comprehensive care to older adults that addresses their physical, psychological, and social needs.

Background: The Decade of Healthy Aging (2021-2030) emerges as a 10 years strategy to improve the lives of older adults, their families, and the communities in which they live. One of the actions defined in this framework is related to improving the measurement, monitoring, and understanding of characteristics, factors, and needs related to aging and health. The aim was to analyze and assess the process of construction and development of the Strategic Information System on Health, Funcional Dependence and Aging (SIESDE, for its acronym in Spanish). SIESDE will provide strategic information in Mexico at the municipal, state, and national levels that support the public policies on healthy aging., Methods: The system processes and analyzes the data sources of the Health Information Systems and the National System of Statistical and Geographical Information. SIESDE comprises three components: (1) Design, construction, and evaluation of the indicators; (2) storage, management, and visualization, and (3) diffusion and translation of information., Results: A total of 135 indicators were built on seven themes: (1) demographic, socioeconomic, and aging conditions, (2) health, (3) functional dependence, (4) healthy aging, (5) health services, (6) social and physical environments, and (7) complex indicators., Conclusions: SIESDE is an effective system for providing an overall view of health, aging, and functional dependence., (© 2024.

Introduction: Social prescribing (SP) is a rapidly growing health and social model of care. The concept of social prescribing is based on well-known clinical practices such as community referrals, integrated health and social care, and navigator models. Although SP began in the United Kingdom's mental health and social care field, there are many examples of different models of SP foci and pathways. Here in Canada, SP is emerging at several provincial locations, with differences in its delivery reflecting the local context of people and places., Competing Interests: ML is the social prescribing change lead and Frailty Pathway project lead employed by Fraser Health. GP is the regional medical director for Home and Community Services, contracted by Fraser Heath. MCA is a professor at The University of British Columbia, with no conflicts to declare.

Executive summary: The age of Canada's population is increasing, necessitating innovative methods and tools for assessing the needs of older adults and identifying effective health and social prescriptions. In Alberta, a community-based, senior-serving organization undertook the development and piloting of the Healthy Aging Asset Index, an assessment tool and social prescribing guide for use by a variety of professionals within the community. Tool development was rooted in medical complexity assessment and social work practice, and adhered to the determinants of healthy aging established by Alberta's Healthy Aging Framework, which is based on the determinants of healthy aging published by the World Health Organization. Results from the pilot showed improvement in the functionality of older adults within the determinants over time, as they were supported in addressing areas of personal vulnerability. Adopting tools such as the Healthy Aging Asset Index can bring cohesiveness to the support that older adults receive across the care continuum and has the potential to shift the balance of care away from the health system and towards the community, thus improving the capacity of health systems and government to meet the needs of Canada's older adults., Competing Interests: All authors declare no conflicts of interest.

Introduction: Physical activity acts as an adjuvant in the treatment of numerous diseases and in the promotion of healthy aging. Increasing longevity entails an increase in the demand for professionals who prescribe physical activity, specifically physiotherapists and physical-activity educators., Objectives: The main objective of this study was to explore the perceptions of a group of third- and fourth-year Physiotherapy students (n=9) and Sport Sciences students (n=5), and experts who work with older adults (n=3) about their knowledge of the older adult population and healthy aging. The secondary objectives were to: (a) explore what knowledge future professionals need about physical activity programming and about physical activity programs aimed at maintaining and improving health among older adults; (b) explore what would be the best methodology to acquire such knowledge; and (c) explore whether a relationship is perceived between knowledge about the older adult population and motivation to work with this population group., Methods: Two discussion groups with students and three interviews with experts were conducted. Discussion groups and interviews were transcribed verbatim and analyzed through a reflexive thematic analysis, following the steps described by Braun and Clarke (2021)., Results: Three themes were identified from the discussion groups: (1) conception and ideas about older adults, (2) skills and knowledge perceived as important, and (3) proposals for motivational intervention addressed to the older population. Four themes were identified from the interviews with experts: (1) characteristics of the future professional, (2) physical activity programs for older people: the recipe for success, (3) the role of enjoyment as key to success, and (4) barriers/obstacles along the path., Conclusion: Students of both degrees and experts believe that more practical training opportunities are needed, to enable students to interact with the older population and get to know their needs, motivations, and barriers, to increase physical activity levels in this population group., (Copyright © 2024 SEGG.

Objectives: This study investigates which local area characteristics, included in the Healthy Ageing/Vulnerable ENvironment (HAVEN) Index, are the strongest factors predicting transition into permanent residential aged care (PRAC) and mortality, and the geographic distribution of these factors., Methods: A retrospective cohort study of older individuals living in the community in Adelaide who received their first eligibility assessment for age care services between 2013 and 2015 (n = 16,939) was conducted. The study cohort, from the Registry of Senior Australians (ROSA), was linked by postcode to HAVEN Index items, selected following item response theory (IRT) analysis to determine the strongest local area factors associated with PRAC and mortality. Geospatial mapping of the factors determined the geographic distribution of these significant factors., Results: Fourteen HAVEN Index items were associated with entry into PRAC and mortality. Three area-level items, lower educational attainment, financial housing stress and low levels of volunteering by older people, were risk factors for entry into PRAC and mortality while the remainder of the items identified were different for each outcome. The mapped local area risk factors for each outcome highlighted similar geographical areas of vulnerability., Conclusions: Local area characteristics are associated with entering PRAC and mortality. Our findings can inform area-level responses to make neighbourhoods more age-friendly, potentially allowing more people to age longer in place. Similar analyses, conducted for other areas, could provide evidence to support the widespread development of age-friendly neighbourhoods reducing area-level inequalities in ageing., (© 2024 The Authors.

Aging is an inevitable and gradual decline in several biological functions. Mitochondrial dysfunction is one of the most important hallmarks of aging. In this context, alterations in metabolites associated with mitochondrial dysfunction may serve as a significant biomarker. This study aimed to investigate the existence of a relationship between the key metabolites involved in bioenergetics metabolism and aging. 53 volunteers ranged 20-85 years participated in the study. We tested the association between different tricarboxylic acid (TCA) cycle metabolites, fatty acid metabolism, and amino acid metabolism with age, sex, body composition, and proxy markers of aging such as walking speed, grip strength and chair test. We found that lactic acid negatively correlated with age while several fatty acid metabolites, such as azelaic, sebacic, and linoleic acids, showed positive correlations with age (p < 0.05). Sex-specific trends, such as glycerol, and dodecanoic acid, were also observed for certain metabolites. Furthermore, citric acid levels were found to have a significant association with physical function and body composition measures. Participants with higher citric acid levels displayed improved performance in physical tests and favorable body composition indices. Additionally, fumaric acid and adipic acid showed positive correlations with fat-free body mass, while sebacic acid was negatively associated with measures of fat mass. These findings underscore the importance of understanding the role of circulating bioenergetics metabolites with age, sex variations, and their potential implications in body composition and physical performance., Competing Interests: Declaration of competing interest The authors declare no competing financial interests., (Copyright © 2024.

Background: Successful aging (SA) describes the multidimensional aspects of achieving optimal physical and mental health and social well-being combinations in old age. Recent years have seen increasing interest in understanding SA prevalence. This study systematically evaluates the current state of SA globally, defined as multidimensional outcomes., Objective: To systematically evaluate the global prevalence of SA in older adults., Methods: We searched PubMed, Embase, Web of Science, Cochrane Library, China Biomedical Database, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and Weipu Database from inception to February 14, 2024. Two researchers independently conducted literature screening, data extraction, and quality evaluation. Meta-analysis was performed using Stata 16.0., Results: Thirty studies comprising 250,460 older adults were included. Meta-analysis showed the overall global prevalence of SA was 24.0 % [95 % CI (20.7 %, 27.3 %)]. Prevalence rates were 25.1 % in Asia, 21.5 % in Europe, 20.6 % in the Americas; 16.8 % in developed and 27.1 % in developing countries. Subgroup analyses indicated higher SA rates among male older adults, married/cohabiting, living in urban areas, and having higher education levels., Conclusions: The global prevalence of SA among older adults is low, with variations across age groups, regions, and education levels. Due to the limitations of the included studies, further high-quality research is needed to validate these findings., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Yoga-based clinical research has shown considerable promise in varied ageing-related health outcomes in older adults. However, robust frameworks have yet to be used in intervention research to endorse yoga as a healthy ageing intervention to test the multidimensional construct of healthy ageing. This was an assessor-masked, randomized controlled trial conducted among 258 sedentary, community-dwelling older adults aged 60-80 years, randomly allocated to 26-week yoga-based intervention (YBI) (n = 132) or waitlist control (WLC) (n = 126). The effectiveness of YBI was assessed through two separate global statistical tests, generalized estimating equations and rank sum-based test, against a comprehensive healthy aging panel comprised of ten markers representing the domains of physiological and metabolic, cognitive, physical capability, psychological, and social well-being. The secondary outcomes were individual primary marker scores, Klotho, inflammatory markers, and auxiliary blood markers. We could establish the healthy aging effect of the 26-week YBI over WLC using two models of global statistical test (GEE, β = 0.29; 95% CI = 0.20 to 0.38, p < 0.001), and rank sum-based test (β = 0.28, 95% CI = 0.19 to 0.36, p < 0.001). There were also significant improvements in direction of benefit at individual levels of all the aging markers. Exploratory evaluation with adopted indices from contemporary clinical trials also validated the potential of YBI for healthy aging; HATICE adapted composite score (mean difference =  - 0.18; 95% CI =  - 0.26 to - 0.09, p < 0.001) and healthy ageing index (mean difference =  - 0.33; 95% CI =  - 0.63 to - 0.02, p = 0.03). The global effect of YBI across multiple ageing-related outcomes provides a proof of concept for further large-scale validation. The findings hold a great translational value given the accelerated pace of population aging across the globe. Trial registration: CTRI/2021/02/031373., (© 2024.

Centenarians represent a phenomenon of successful aging. This systematic review aimed to understand lifestyles and health practices, focusing on diet and medication use for healthy longevity in community-based adults 95 years or over. Medline, CINAHL, Scopus, and gray literature were searched from 1 January 2000 to 10 December 2022. Study quality was assessed using the Modified Newcastle-Ottawa Scale (mNOS). Pooled prevalence [%; 95% confidence interval] for categorical variables and pooled mean for continuous variables were estimated for demographics, weight status, lifestyle factors, medications, and health conditions. Of 3392 records screened, 34 studies were included in the review, and 71% (24/34) met the 6/8 criteria in mNOS. Centenarians/near-centenarians' ages ranged from 95 to 118 years, with 75% (71-78%) female and 78% (68-88%) living in rural areas. They had an overall healthy lifestyle: current smoking (7%; 5-9%), drinking (23%; 17-30%), normal weight (52%; 42-61%), overweight (14%; 8-20%), physical activity (23%; 20-26%), and sleep satisfaction (68%; 65-72%). Diet averaged 59.6% carbohydrate, 18.5% protein, and 29.3% fat; over 60% consumed a diverse diet, and < 20% preferred salty food, contributing to lower mortality risks and functional decline. About half used antihypertensives (49%; 14-84%) or other cardiovascular drugs (48%; 24-71%), with an average of 4.6 medications. Common health issues included impaired basic activities of daily living (54%; 33-74%), hypertension (43%; 21-65%), and dementia (41%; 23-59%). The findings of this systemic review underscore the pivotal role of dietary practice and weight management in healthcare strategies to promote healthy ageing. It also recognises rural living styles and sleep hygiene as potential factors contributing to healthy longevity., (© 2024. The Author(s).)

As the population ages, promoting healthy aging through targeted interventions becomes increasingly crucial. Growing evidence suggests that dietary interventions can significantly impact this process by modulating fundamental molecular pathways. This review focuses on the potential of targeted dietary strategies in promoting healthy aging and the mechanisms by which specific nutrients and dietary patterns influence key pathways involved in cellular repair, inflammation, and metabolic regulation. Caloric restriction, intermittent fasting, the Mediterranean diet, as well as the ketogenic diet showed promising effects on promoting healthy aging, possibly by modulating mTORC1 AMPK, an insulin signaling pathway. By understanding the intricate interplay between diet and molecular pathways, we can develop personalized dietary strategies that not only prevent age-related diseases, but also promote overall health and well-being throughout the aging process.

Cellular senescence, a form of terminal cell cycle arrest, is as a key driver of organismal ageing and an important factor in age-related diseases. Insights into the senescent phenotype have led to the development of novel therapeutic strategies, collectively known as senotherapies, that aim to ameliorate the detrimental effects of senescent cell accumulation in tissues. The senotherapeutic field has rapidly evolved over the past decade, with clinical translation of the first drugs discovered currently underway. What began as the straightforward removal of senescent cells using repurposed compounds, which were given the name of senolytics, has grown into an expanding field that uses different state of the art approaches to achieve the goal of preventing the build-up of senescent cells in the body. Here, we summarize the emergence of a new generation of senotherapies, based on improving the efficacy and safety of the original senolytics by making them targeted, but also branching out into drugs that prevent senescence (senoblockers) or revert it (senoreversers).The use of nanotechnology, specific antibodies, cell-based approaches and restored immunosurveillance is likely to revolutionize the field of senotherapies in the near future, hopefully allowing it to realize its full clinical potential., (© 2024 The Author(s).

Background: Falls frequently occur among the older adult population. In this study, we examined the variations in fall incidence across different regions over time, focusing on the disparities between urban and rural areas among older adult Chinese individuals, Healthy aging is comprised of five dimensions: (1) absence of chronic diseases, (2) good physical functioning, (3) normal cognitive function, (4) active social participation, and (5) absence of depression. Additionally, we explored the relationship between healthy aging and the occurrence of falls in middle-aged and older adults. Falls are defined as events that occurred within the past two years., Results: Among 9,918 participants, 33.8% lived in urban areas and 23.0% achieved healthy aging. In contrast, 66.2% resided in rural areas with 16.5% achieving healthy aging. In 2011, rural residents had a higher fall incidence rate (17% in rural vs. 13.5% in urban); by 2020, the fall rate remained higher in rural areas (19.5% in rural vs. 17.3% in urban). Unhealthy aging (HR = 1.08, 95%CI: 1.00-1.16) were risk factors for falls. Subgroup analysis revealed that in rural areas, unhealthy aging increased the risk of falls. In urban areas, the increased risk of falls associated with unhealthy aging was not significant (Rural HR = 1.11, 95%CI:1.01-1.22; Urban HR = 1.05, 95%CI: 0.93-1.18)., Conclusion: Healthy aging may be more strongly associated with a lower risk of falls in rural areas, while this association might be less pronounced in urban areas due to different environmental and social factors. This highlights the need for environment-specific fall prevention strategies and targeted measures for the older adult., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Li, Wei, Hu, Sun, Gao and Yang.)

Background: The rapidly aging population and the growth of geriatric medicine in the field of internal medicine are not supported by sufficient gerontological training in many health care disciplines. There is rising awareness about the education and training needed to adequately prepare health care professionals to address the needs of the older adult population. Massive open online courses (MOOCs) might be the best alternative method of learning delivery in this context. However, the diversity of MOOC participants poses a challenge for MOOC providers to innovate in developing learning content that suits the needs and characters of participants., Objective: The primary outcome of this study was to explore students' perceptions and acceptance of HTML5 package (H5P) interactive content in self-paced MOOCs and its association with students' characteristics and experience in using MOOCs., Methods: This study used a cross-sectional design, combining qualitative and quantitative approaches. Participants, predominantly general practitioners from various regions of Indonesia with diverse educational backgrounds and age groups, completed pretests, engaged with H5P interactive content, and participated in forum discussions and posttests. Data were retrieved from the online questionnaire attached to a selected MOOC course. Students' perceptions and acceptance of H5P interactive content were rated on a 6-point Likert scale from 1 (strongly disagree) to 6 (strongly agree). Data were analyzed using SPSS (IBM Corp) to examine demographics, computer literacy, acceptance, and perceptions of H5P interactive content. Quantitative analysis explored correlations, while qualitative analysis identified recurring themes from open-ended survey responses to determine students' perceptions., Results: In total, 184 MOOC participants agreed to participate in the study. Students demonstrated positive perceptions and a high level of acceptance of integrating H5P interactive content within the self-paced MOOC. Analysis of mean (SD) value across all responses consistently revealed favorable scores (greater than 5), ranging from 5.18 (SD 0.861) to 5.45 (SD 0.659) and 5.28 (SD 0.728) to 5.52 (SD 0.627), respectively. This finding underscores widespread satisfaction and robust acceptance of H5P interactive content. Students found the H5P interactive content more satisfying and fun, easier to understand, more effective, and more helpful in improving learning outcomes than material in the form of common documents and learning videos. There is a significant correlation between computer literacy, students' acceptance, and students' perceptions., Conclusions: Students from various backgrounds showed a high level of acceptance and positive perceptions of leveraging H5P interactive content in the self-paced MOOC. The findings suggest potential new uses of H5P interactive content in MOOCs, such as interactive videos with pop-up questions, to substitute for synchronous learning. The study underscores the significance of tailored educational strategies in supporting the professional development of health care professionals., (©Pratiwi Rahadiani, Aria Kekalih, Diantha Soemantri, Desak Gede Budi Krisnamurti.

Aging-related disorders pose significant challenges due to their complex interplay of physiological and metabolic factors, including inflammation, oxidative stress, and mitochondrial dysfunction. Curcumin, a natural compound with potent antioxidant and anti-inflammatory properties, has emerged as a promising candidate for mitigating these age-related processes. However, gaps in understanding the precise mechanisms of curcumin's effects and the optimal dosages for different conditions necessitate further investigation. This systematic review synthesizes current evidence on curcumin's potential in addressing age-related disorders, emphasizing its impact on cognitive function, neurodegeneration, and muscle health in older adults. By evaluating the safety, efficacy, and mechanisms of action of curcumin supplementation, this review aims to provide insights into its therapeutic potential for promoting healthy aging. A systematic search across three databases using specific keywords yielded 2256 documents, leading to the selection of 15 clinical trials for synthesis. Here, we highlight the promising potential of curcumin as a multifaceted therapeutic agent in combating age-related disorders. The findings of this review suggest that curcumin could offer a natural and effective approach to enhancing the quality of life of aging individuals. Further research and well-designed clinical trials are essential to validate these findings and optimize the use of curcumin in personalized medicine approaches for age-related conditions.

Purpose: Growing elderly populations worldwide have sparked interest in factors promoting healthy aging. Diet and other lifestyle patterns are key factors for healthy ageing; however, evidence is sparse for specific dietary guidelines that are easily implemented in everyday life. Whole grains constitute specific dietary components with unexplored potential in healthy ageing., Methods: We applied an illness-death multistate model to assess the association between whole-grain intake and life expectancy, both with and without disease, over a 20-year period. Healthy ageing was defined as absence of cancer, ischemic heart disease, stroke, type 2 diabetes, asthma, chronic obstructive pulmonary disease, and dementia during follow-up., Results: Based on information from 22,606 men and 25,468 women in the Danish Diet, Cancer and Health cohort, followed for an average of 13.8 and 17.5 years, respectively, a doubling in whole-grain intake was associated with 0.43 (95% CI: 0.33-0.52) and 0.15 (0.06-0.24) additional years without disease for men and women, respectively. Comparing the highest and lowest quartiles of whole-grain intake, with a special emphasis on men, we found that those with the highest intake lived, on average, one year longer without disease compared to those with the lowest intake. Additionally, although a high intake of whole grains yielded longer life expectancy, the duration of living with disease was shorter., Conclusion: Intake of whole grains in mid-life was associated with healthy ageing looking 20 years ahead., (© 2024.

Healthy aging has emerged as a crucial issue with the increase in the geriatric population worldwide. Food-derived sulfur-containing amino acid ergothioneine (ERGO) is a potential dietary supplement, which exhibits various beneficial effects in experimental animals although the preventive effects of ERGO on aging and/or age-related impairments such as frailty and cognitive impairment are unclear. We investigated the effects of daily oral supplementation of ERGO dissolved in drinking water on lifespan, frailty, and cognitive impairment in male mice from 7 weeks of age to the end of their lives. Ingestion of 4 ~ 5 mg/kg/day of ERGO remarkably extended the lifespan of male mice. The longevity effect of ERGO was further supported by increase in life and non-frailty spans of Caenorhabditis elegans in the presence of ERGO. Compared with the control group, the ERGO group showed significantly lower age-related declines in weight, fat mass, and average and maximum movement velocities at 88 weeks of age. This was compatible with dramatical suppression by ERGO of the age-related increments in plasma biomarkers (BMs) such as the chemokine ligand 9, creatinine, symmetric dimethylarginine, urea, asymmetric dimethylarginine, quinolinic acid, and kynurenine. The oral intake of ERGO also rescued age-related impairments in learning and memory ability, which might be associated with suppression of the age-related decline in hippocampal neurogenesis and TDP43 protein aggregation and promotion of microglial shift to the M2 phenotype by ERGO ingestion. Ingestion of ERGO may promote longevity and healthy aging in male mice, possibly through multiple biological mechanisms., (© 2024. The Author(s).)

Models of healthy aging are typically based on the United States and Europe and may not apply to diverse and heterogeneous populations. In this study, our objectives were to conduct a meta-analysis to assess risk factors of cognition and functional ability across aging populations in Latin America and a scoping review focusing on methodological procedures. Our study design included randomized controlled trials and cohort, case-control and cross-sectional studies using multiple databases, including MEDLINE, the Virtual Health Library and Web of Science. From an initial pool of 455 studies, our meta-analysis included 38 final studies (28 assessing cognition and 10 assessing functional ability, n = 146,000 participants). Our results revealed significant but heterogeneous effects for cognition (odds ratio (OR) = 1.20, P = 0.03, confidence interval (CI) = (1.0127, 1.42); heterogeneity: I 2  = 92.1%, CI = (89.8%, 94%)) and functional ability (OR = 1.20, P = 0.01, CI = (1.04, 1.39); I 2  = 93.1%, CI = (89.3%, 95.5%)). Specific risk factors had limited effects, especially on functional ability, with moderate impacts for demographics and mental health and marginal effects for health status and social determinants of health. Methodological issues, such as outliers, inter-country differences and publication bias, influenced the results. Overall, we highlight the specific profile of risk factors associated with healthy aging in Latin America. The heterogeneity in results and methodological approaches in studying healthy aging call for greater harmonization and further regional research to understand healthy aging in Latin America., (© 2024.

Objectives: This study aimed to assess the trends of healthy aging and investigate its determinants in the middle-aged population., Study Design: This was a longitudinal study., Methods: The sample comprised 3043 participants aged 45-59 years from the China Longitudinal Study of Health and Retirement 2011-2018. We plotted the prevalence across four waves and used ordered logistic models to investigate the determinants of cumulative times of healthy aging., Results: We enrolled 3043 middle-aged people in our study. The prevalence of healthy aging is 28.2% at baseline but subsequently decreased to 19.72% at wave 4. Active socializing consistently ranked the lowest among the five dimensions. Participants with older age (odds ratio [OR] = 0.95, 95% confidence interval [CI] = 0.94-0.97), low monthly income (OR = 0.82, 95% CI: 0.69-0.97) or lived in urban (OR = 0.81, 95% CI: 0.70-0.94) were less likely to have per time increase in healthy aging. Participants with more than primary school degree (OR = 1.79, 95% CI: 1.31-2.46), high life satisfaction (OR = 2.38, 95% CI: 1.86-3.06), and good self-report health (OR = 1.97, 95% CI: 1.66-2.34) were more likely to have healthy aging., Conclusion: The number of middle-aged individuals in China who achieved healthy aging is declining and eventually less than one in five, which was far from ideal. Particular attention should be paid to older, women, urban dwellers, individuals with low income, low life satisfaction or poor self-report health. It is urgent to develop public health policies to improve the health and well-being of the middle-aged population., (Copyright © 2024 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

Clocks that measure biological age should predict all-cause mortality and give rise to actionable insights to promote healthy aging. Here we applied dimensionality reduction by principal component analysis to clinical data to generate a clinical aging clock (PCAge) identifying signatures (principal components) separating healthy and unhealthy aging trajectories. We found signatures of metabolic dysregulation, cardiac and renal dysfunction and inflammation that predict unsuccessful aging, and we demonstrate that these processes can be impacted using well-established drug interventions. Furthermore, we generated a streamlined aging clock (LinAge), based directly on PCAge, which maintains equivalent predictive power but relies on substantially fewer features. Finally, we demonstrate that our approach can be tailored to individual datasets, by re-training a custom clinical clock (CALinAge), for use in the Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE) study of caloric restriction. Our analysis of CALERIE participants suggests that 2 years of mild caloric restriction significantly reduces biological age. Altogether, we demonstrate that this dimensionality reduction approach, through integrating different biological markers, can provide targets for preventative medicine and the promotion of healthy aging., (© 2024.

Healthy ageing is defined as 'the process of developing and maintaining the functional ability that enables well-being in older age' ( World Health Organization 2015 ). Key factors for healthy ageing are subdivided into intrinsic capacity such as motor, cognitive and sensory function, and extrinsic factors such as health and social care systems, and support from charities, volunteers and the private sector ( Ellis et al 2018 )., (©2024 RCN Publishing Company Ltd.

Background and Objective: Understanding the domains of healthy aging (HA) through the perceptions of older adults is important for the multidimensional determination of the construct according to the culture of Peru and for the development of plans that promote the health, well-being, resources and strengths of older adults. The purpose of this study is to qualitatively explore the operational domains of HA in Peruvian older adults., Method: The approach adopted was fundamental qualitative descriptive. A purposive sampling was used and 26 participants attending senior centers belonging to the municipal commune of Lima were recruited (Medad=67.9; SD=6.64). Semi-structured interviews were conducted and the content analysis was carried out using an inductive method identifying the units of meaning of the HA., Results: The content analysis showed 11 sub-themes and 4 main themes. The identified themes were as follows: "functional health", "psychological well-being", "active engagement with life" and "religion". Given this, the results demonstrate the multidimensionality of HA in Peruvian older adults., Conclusion: The operational domains of HA indicate the importance of individual perceptions considering functional health, psychological well-being, active engagement with life, and religion. This perspective supports the multidimensional concept of HA. This can be implemented as a guide for government entities working with PAMs. In addition, to formulate new public policies focusing on the domains of HA., (Copyright © 2024 SEGG.

The article considers issues of potential of public organizations to develop conditions for healthy aging in order to ensure sustainable development of Russian regions differing in their socio-economic, socio-cultural and demographic characteristics. It is established that individual approach is to be applied in developing and implementing measures, since elderly Russians constitute very heterogeneous social demographic group, characterizing by differences in age, health condition, social, economic and professional status, life motivation, family/single/nursing type of residence, etc. It is indicated that work will require time, financial expenses and labor costs. The achievement of sustainable development of Russian regions depends on ability and readiness of regional and municipal authorities, public and commercial organizations and entire population. It is determined that age-related stigmatization and ageism can not be overcame through decisions made by persons of power. No less significant is public opinion, determining position of employers, physicians, teachers and other specialists on whom healthy longevity of population depends. The conclusion is made that present demographic changes are a predictor of development of position of state authorities and public opinion that needed attention is to be paid to promoting of healthy aging, to expending necessary financial, infrastructural, informational and human resources. Only in this case Russian regions can count on social dividends that will follow preliminary comprehensive investments into developing conditions for healthy aging of local residents.

The Georgia Centenarian Study is one of the earliest comprehensive studies on centenarians. Based on the Georgia model of adaptation, the primary purpose of this study was to assess the health and well-being of our oldest population, with a focus on several primary adaptation areas: genetics and family longevity, environmental support, individual characteristics, cognitive and behavioral skills, health behaviors, and physical and mental health, including overall life satisfaction. The results of the three Georgia Centenarian sub-studies indicate that genetic and environmental variables play an important role in determining different levels of healthy aging, but they also highlight relevant mediating and moderating effects in a network of interrelating adaptation components., Competing Interests: Declaration of competing interest The authors declare that they have no competing interest., (Copyright © 2024 Elsevier B.V.

Aging is associated with a decline in physiological functions and an increased risk of age-related diseases, emphasizing the importance of identifying dietary strategies for healthy aging. Minerals play a crucial role in maintaining optimal health during aging, making them relevant targets for investigation. Therefore, we aimed to analyze the effect of different dietary pattern on mineral status in the elderly. We included 502 individuals aged 50-80 years in a 36-month randomized controlled trial (RCT) (NutriAct study). This article focuses on the results within the two-year intervention period. NutriAct is not a mineral-modulating-targeted intervention study, rather examining nutrition in the context of healthy aging in general. However, mineral status might be affected in an incidental manner. Participants were assigned to either NutriAct dietary pattern (proportionate intake of total energy consumption (%E) of 35-45 %E carbohydrates, 35-40 %E fats, and 15-25 %E protein) or the German Nutrition Society (DGE) dietary pattern (proportionate intake of total energy consumption (%E) of 55 %E carbohydrates, 30 %E fats, and 15 %E protein), differing in the composition of macronutrients. Data from 368 participants regarding dietary intake (energy, calcium, magnesium, iron, and zinc) and serum mineral concentrations of calcium, magnesium, iron, copper, zinc, selenium, iodine, and manganese, free zinc, and selenoprotein P were analyzed at baseline, as well as after 12 and 24 months to gain comprehensive insight into the characteristics of the mineral status. Additionally, inflammatory status - sensitive to changes in mineral status - was assessed by measurement of C-reactive protein and interleukin-6. At baseline, inadequate dietary mineral intake and low serum concentrations of zinc and selenium were observed in both dietary patterns. Throughout two years, serum zinc concentrations decreased, while an increase of serum selenium, manganese and magnesium concentrations was observable, likely influenced by both dietary interventions. No significant changes were observed for serum calcium, iron, copper, or iodine concentrations. In conclusion, long-term dietary interventions can influence serum mineral concentrations in a middle-aged population. Our findings provide valuable insights into the associations between dietary habits, mineral status, and disease, contributing to dietary strategies for healthy aging., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest., (Copyright © 2024.

The pursuit of enhanced health during aging has prompted the exploration of various strategies focused on reducing the decline associated with the aging process. A key area of this exploration is the management of mitochondrial dysfunction, a notable characteristic of aging. This review sheds light on the crucial role that small molecules play in augmenting healthy aging, particularly through influencing mitochondrial functions. Mitochondrial oxidative damage, a significant aspect of aging, can potentially be lessened through interventions such as coenzyme Q10, alpha-lipoic acid, and a variety of antioxidants. Additionally, this review discusses approaches for enhancing mitochondrial proteostasis, emphasizing the importance of mitochondrial unfolded protein response inducers like doxycycline, and agents that affect mitophagy, such as urolithin A, spermidine, trehalose, and taurine, which are vital for sustaining protein quality control. Of equal importance are methods for modulating mitochondrial energy production, which involve nicotinamide adenine dinucleotide boosters, adenosine 5'-monophosphate-activated protein kinase activators, and compounds like metformin and mitochondria-targeted tamoxifen that enhance metabolic function. Furthermore, the review delves into emerging strategies that encourage mitochondrial biogenesis. Together, these interventions present a promising avenue for addressing age-related mitochondrial degradation, thereby setting the stage for the development of innovative treatment approaches to meet this extensive challenge., (© 2024 Wiley Periodicals LLC.)

Objective: This study aims to investigate the mediating role of self-neglect among older adults in the relationship between family functioning and healthy aging., Methods: A questionnaire survey was conducted between June and September 2023, involving 255 older adults living alone in rural China. The healthy ageing, self-neglect, and family functioning was assessed using the Healthy Aging Instrument;the Elderly Self-neglect Assessment (Rural);and Family Adaptation, Partnership, Growth, Affection, and Resolve (APGAR) scale., Results: Positive correlations were found between family functioning and healthy aging (r = 0.363, p < 0.05). Moreover, self-neglect was identified as a significant mediator, explaining 40.84 % of the total effect., Conclusion: Among older adults living alone in rural China, family functioning is significantly associated with healthy aging, with self-neglect mediating this relationship. These findings suggest that community-based interventions aimed at improving family functioning and addressing self-neglect behaviors might be beneficial for promoting healthy aging in this population., Competing Interests: Declaration of competing interest The authors declared no conflict of interest., (Copyright © 2024 Elsevier Inc.

Frailty and quality of life are concepts that emerged in the second half of the 20th century. Frailty can be defined as a clinical syndrome of decreased physiological reserves and resistance against stressful events conferring high risk for adverse health outcomes, including loss of independence, falls, hospitalization, institutionalization and mortality. However, it is considered that frailty can potentially be prevented or treated with specific modalities. Quality of life has various definitions because of its subjective nature. The World Health Organisation defined quality of life as “an individual’s perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns”. The aim of this study is to review information regarding the potential association between frailty and quality of life in the elderly, and the effects of physical activity among different parameters of these phenomena. There are few studies that investigate links between frailty, quality of life and physical activity. However, results tend to show that physical aspects of frailty syndrome are inversely proportional to the quality of life in several of its dimensions. Furthermore, community-based exercise programs involving the elderly seem to improve the quality of life. Considering that physical activity can potentially have an impact on the quality of life among frail elderly and promote healthy aging, further research will be necessary to corroborate these results.

Objectives: This study aimed to evaluate the potential clinical value of a new brain age prediction model as a single interpretable variable representing the condition of our brain. Among many clinical use cases, brain age could be a novel outcome measure to assess the preventive effect of life-style interventions., Methods: The REMEMBER study population (N = 742) consisted of cognitively healthy (HC,N = 91), subjective cognitive decline (SCD,N = 65), mild cognitive impairment (MCI,N = 319) and AD dementia (ADD,N = 267) subjects. Automated brain volumetry of global, cortical, and subcortical brain structures computed by the CE-labeled and FDA-cleared software icobrain dm (dementia) was retrospectively extracted from T1-weighted MRI sequences that were acquired during clinical routine at participating memory clinics from the Belgian Dementia Council. The volumetric features, along with sex, were combined into a weighted sum using a linear model, and were used to predict 'brain age' and 'brain predicted age difference' (BPAD = brain age-chronological age) for every subject., Results: MCI and ADD patients showed an increased brain age compared to their chronological age. Overall, brain age outperformed BPAD and chronological age in terms of classification accuracy across the AD spectrum. There was a weak-to-moderate correlation between total MMSE score and both brain age (r = -0.38,p < .001) and BPAD (r = -0.26,p < .001). Noticeable trends, but no significant correlations, were found between BPAD and incidence of conversion from MCI to ADD, nor between BPAD and conversion time from MCI to ADD. BPAD was increased in heavy alcohol drinkers compared to non-/sporadic (p = .014) and moderate (p = .040) drinkers., Conclusions: Brain age and associated BPAD have the potential to serve as indicators for, and to evaluate the impact of lifestyle modifications or interventions on, brain health., (© 2024.

Objective: Through interviews with older adults and professionals in Chongqing, China, this paper explores the challenges and opportunities faced by smart cities that undertake to better support ageing-in-place., Methods: We undertook a qualitative multi-methods approach, engaging 46 professional stakeholders and 64 older people to examine the role of smart cities in enabling older people to age-in-place in Chongqing, China., Results: With the development of smart cities, technology has the potential to facilitate ageing-in-place by creating opportunities for heathy and active ageing. This study identified specific priorities in delivering age-friendly smart cities, including the following: shaping smart environments around the everyday lives of older people, designing inclusive and equitable smart cities and ensuring strong forms of institutional governance, trust and relationship building with older people., Conclusions: The age-friendly city and communities movement (AFCC) and smart city policy instruments have potential for realising active ageing by supporting mobility, access to services and civic participation. However, there exists a disconnect between smart city policy and practice in delivering tangible well-being outcomes for older people. Addressing this requires greater cross-sectoral working, reconciling smart city policy priorities with AFCC domains and creating the institutional and governance framework to enable socially sustainable cities to support ageing-in-place., (© 2024 The Authors.

Many physical, social, and psychological changes occur during aging that raise the risk of developing chronic diseases, frailty, and dependency. These changes adversely affect the gut microbiota, a phenomenon known as microbe-aging. Those microbiota alterations are, in turn, associated with the development of age-related diseases. The gut microbiota is highly responsive to lifestyle and dietary changes, displaying a flexibility that also provides anactionable tool by which healthy aging can be promoted. This review covers, firstly, the main lifestyle and socioeconomic factors that modify the gut microbiota composition and function during healthy or unhealthy aging and, secondly, the advances being made in defining and promoting healthy aging, including microbiome-informed artificial intelligence tools, personalized dietary patterns, and food probiotic systems.

Dietary interventions are a key strategy to promote healthy ageing. Cooking skills training emerges as a promising approach to acquiring and maintaining healthy eating habits. The purpose was to evaluate the effectiveness of a culinary programme to improve healthy eating habits among overweight/obese adults (55-70 years old). A total of 62 volunteers were randomly (1:1) assigned to an culinary intervention group (CIG) or a nutritional intervention group (NIG). Dietary, cooking, and health-related outcomes, including body advanced glycation end product (AGE) levels, were evaluated at baseline and after four weeks. Mixed-effects linear models were used to assess the effects of the interventions within and between groups. Among the 56 participants who completed the trial, CIG participants achieved a significant improvement in Mediterranean diet adherence (1.2; 95%CI, 0.2 to 2.2) and a reduction in the use of culinary techniques associated with a higher AGE formation in foods (-2.8; 95%CI, -5.6 to -0.2), weight (-1.5; 95%CI, -2.5 to -0.5), body mass index (-0.5; 95%CI, -0.8 to -0.2), waist circumference (-1.4; 95%CI, -2.6 to -0.2), and hip circumference (-1.4; 95%CI, -2.4 to -0.4) compared with the NIG participants. Although a greater confidence in cooking in the CIG was found, attitudes and cooking habits did not improve. No significant differences in biochemical parameters or AGEs were found between groups. In conclusion, a culinary intervention could be successful in promoting healthy eating and cooking habits compared to a programme based on nutrition education alone. Nevertheless, further efforts are needed to strengthen attitudes and beliefs about home cooking, to address potential barriers and understand the impact of cooking interventions on biological parameters. Larger studies with longer follow-ups are needed to evaluate the relationship between cooking, diet, and health.
