Protocol for a feasibility randomized controlled trial of gentle yoga in older patients discharged from phase II cardiac rehabilitation.

Background: Physical activity (PA) is essential following an acute cardiac event. Cardiac rehabilitation (CR) is commonly prescribed, and PA after CR is recommended. Because of age-related changes in functional ability and multi-comorbidity, many older cardiac patients struggle to continue performing PA at home after CR. Depressive symptoms and anxiety are prevalent in cardiac patients and associated with poor self-care, including lack of daily PA. Yoga has been demonstrated to improve psychological and physical health outcomes in cardiac patients, but it is unknown whether yoga, modified for older CR patients - Gentle Yoga - is beneficial in managing psychological distress and maintaining PA following phase II CR. Our specific aims are to:1) determine the feasibility and acceptability of a modified gentle yoga intervention delivered via video conferencing for older cardiac patients; 2) compare, at 3-month follow-up, the effects and determine effect sizes of a gentle yoga intervention versus control on psychological health and physical health. Methods: We are conducting a 2-group (intervention versus control) randomized controlled pilot study. The intervention is a 12-week gentle yoga program delivered via video conference. Short-term effects will be evaluated at 3-month. Conclusion: This study is designed to be suited for older cardiac patients who would not have access to supervised PA opportunities after facility-based CR to enhance PA. This study will provide data about the feasibility and acceptability of the protocol for older cardiac patients and will offer effect sizes to determine sample size for a fully powered randomized controlled trial.

Food insecurity and mobility difficulty in middle-aged and older adults: The importance of bio-psychosocial factors.

OBJECTIVE: Food insecurity has been associated with mobility difficulty (MD) in old age. However, there is a scarcity of research on this topic from low- and middle-income countries, while the bio-psychological factors underlying this association are largely unknown. We investigated the food insecurity-MD link in Ghana and explored how sleep, anxiety, loneliness, and physical activity (PA) mediate the association. METHODS: Community-based, representative cross-sectional data from the Aging, Health, Well-being, and Health-seeking Behavior Study were analyzed (N = 1201; Mage = 66.5; women = 63%). MD was assessed with items from the SF-36 of the Medical Outcomes Study. We assessed food insecurity with items on hunger and breakfast-skipping frequency due to lack of food and resources. Adjusted OLS and mediation models via bootstrapping technique evaluated the associations. RESULTS: Results revealed the expected association between food insecurity and MD, such that greater food insecurity was significantly and positively associated with MD across paths (from ß = 0.33 to ß = 0.42, p < .001). Analyses of indirect effects showed that sleep problems (27.8%), anxiety (15.5%), loneliness (17.5%), and PA (18.0%) mediated the association between food insecurity and MD. Cross-level interactions revealed that food insecurity significantly modified the link between each mediator and MD. CONCLUSIONS: Our data provide novel evidence that bio-psychological mechanisms may underlie the food insecurity-MD link and should, therefore, be considered relevant targets for interventions to prevent/manage MD in later life.

Association between dietary (poly)phenol intake and the ATHLOS Healthy Ageing Scale in the Polish arm of the HAPIEE study.

Inverse association between (poly)phenol intake and age-related disorders has been demonstrated; however, little is known whether they affect comprehensively assessed healthy aging. The aim of this study was to evaluate the associations between the intake of (poly)phenol (including selected classes and subclasses) and healthy aging scores related to biopsychosocial aspects of health and functioning. A cross-sectional study was performed using data on 9774 randomly selected citizens of Krakow (Poland) who were 45-69 years of age. Dietary (poly)phenol intake was evaluated using a food frequency questionnaire and matching food consumption data with the Phenol-Explorer database. The healthy aging scores were estimated from the ATHLOS Healthy Ageing Scale (HAS) developed by the Ageing Trajectories of Health-Longitudinal Opportunities and Synergies (ATHLOS) consortium. Beta coefficients were calculated using multivariable linear regression models. In multivariable adjusted models, there were significant positive associations between the ATHLOS HAS score and intake of total (poly)phenols (b per increase of 100 mg/day = 0.081; 95% CI, 0.050; 0.112) and among main classes of (poly)phenols with phenolic acids (b = 0.139; 95% CI, 0.098; 0.180). Intake of remaining classes of (poly)phenols (flavonoids, lignans, stilbenes, and others) was not related to the ATHLOS HAS score. Among individual classes studied, hydroxycinnamic acids, flavonols, flavones, and dihydrochalcones were associated with better healthy aging. The findings suggest the beneficial effect of total dietary (poly)phenol and some classes and subclasses of (poly)phenol intake in terms of healthy aging in Poland. These findings should be confirmed in other settings and with prospective data.

Social Robots for Meaningful Seated Activities: Acceptance & Use by Older Adults.

Healthy aging requires the maintenance of good physical and cognitive activity. However, as they age, older adults often experience a decline in physical and cognitive activity, leading to a more sedentary lifestyle. Some older adults may not have a choice but to become increasingly sedentary as they age due to injury or deteriorated physicality. As such, they require assistive technologies to aid in their daily lives and activities to maintain healthy cognitive function. Social Robots are a newer form of assistive technology, specifically designed for social interactions and gameplay. As with other assistive technologies, compliance barriers to their acceptance and use for meaningful, seated activities among older adults are expected. To better explore this phenomenon, improve quality of life and understand what drives older adults to accept and use newer forms of technology like social robots, this conceptual paper conjoins two theoretical frameworks: The Activity Theory of Aging (ATA) and the Unified Theory of Acceptance and Use of Technology (UTAUT). As social robots hold great promise for improving the quality of life for older adults, exploring what driving factors could enable their greater acceptance and use is essential to furthering this field of study within Australia.

Necessity and influencing factors for integrating oral health in cancer care for older people: a narrative review.

PURPOSE: The number of older people with poor oral health diagnosed with cancer is increasing rapidly. However, integration of oral health in cancer care for older people to prevent or minimize oral health complications of cancer treatments is uncommon, except in head and neck oncology. The aim of this review is to describe the need, role of, and factors influencing the integration of oral health(care) into the treatment of older people with cancer. METHODS: MEDLINE, CINAHL, PubMed, Scopus, and Web of Science databases were searched for papers published in the last 10 years that focus on oral health in older people diagnosed with cancer, the impact of oral health on cancer therapy, and integrated oral health in cancer treatment. RESULTS: From 523 related papers, 68 publications were included and summarized as follows: (1) oral complications associated with cancer therapies, (2) the need for oral healthcare in older people with cancer, (3) the role of integration of oral health in cancer care, and (4) influencing factors such as ageism, interprofessional education and collaborations, oral healthcare workforce, oral health literacy, and financial considerations. CONCLUSION: Integration of oral healthcare is highly recommended for the overall well-being of older people with cancer to prevent, minimize, and manage complications in cancer treatment. However, oral healthcare has not been integrated in cancer care yet, except for head and neck cancers. This review identified a notable gap in the literature, highlighting the need for research on integration of oral healthcare in geriatric oncology.

Social Determinants of Health and Biological Age among Diverse U.S. Adults, NHANES 2011-2018.

We examined the sex-specific association between education and income with biological age (BA) and by race/ethnicity. The Klemera-Doubal method was used to calculate BA among 6,213 females and 5,938 males aged 30-75 years who were Hispanic, non-Hispanic (NH) White, NH Black (NHB), or NH Asian (NHA). Compared with a college education, less than a high school education was associated with greater BA by 3.06 years (95% CI: 1.58, 4.54) among females only; associations were strongest among NHB, Hispanic, and NHA females. Compared with an annual income of ≥$75,000, an income <$25,000 was associated with greater BA by 4.95 years (95% CI: 3.42, 6.48) among males and 2.76 years among females (95% CI: 1.51, 4.01); associations were strongest among NHW and NHA adults, and Hispanic males. Targeting upstream sources of structural disadvantage among racial/ethnic minority groups, in conjunction with improvements in income and education, may promote healthy aging in these populations.

Metabolite T2 relaxation times decrease across the adult lifespan in a large multi-site cohort.

Purpose: Relaxation correction is crucial for accurately estimating metabolite concentrations measured using in vivo magnetic resonance spectroscopy (MRS). However, the majority of MRS quantification routines assume that relaxation values remain constant across the lifespan, despite prior evidence of T2 changes with aging for multiple of the major metabolites. Here, we comprehensively investigate correlations between T2 and age in a large, multi-site cohort. Methods: We recruited approximately 10 male and 10 female participants from each decade of life: 18-29, 30-39, 40-49, 50-59, and 60+ years old (n=101 total). We collected PRESS data at 8 TEs (30, 50, 74, 101, 135, 179, 241, and 350 ms) from voxels placed in white-matter-rich centrum semiovale (CSO) and gray-matter-rich posterior cingulate cortex (PCC). We quantified metabolite amplitudes using Osprey and fit exponential decay curves to estimate T2. Results: Older age was correlated with shorter T2 for tNAA, tCr3.0, tCr3.9, tCho, Glx, and tissue water in CSO and PCC; rs = -0.21 to -0.65, all p<0.05, FDR-corrected for multiple comparisons. These associations remained statistically significant when controlling for cortical atrophy. T2 values did not differ across the adult lifespan for mI. By region, T2 values were longer in the CSO for tNAA, tCr3.0, tCr3.9, Glx, and tissue water and longer in the PCC for tCho and mI. Conclusion: These findings underscore the importance of considering metabolite T2 changes with aging in MRS quantification. We suggest that future 3T work utilize the equations presented here to estimate age-specific T2 values instead of relying on uniform default values.

Gut microbiota in centenarians: A potential metabolic and aging regulator in the study of extreme longevity.

Centenarians, those aged 100 years or older, are considered the most successful biological aging model in humans. This population is commonly characterized by a low prevalence of chronic diseases, with favorable maintenance of functionality and independence, thus determining a health phenotype of successful aging. There are many factors usually associated with extreme longevity: genetics, lifestyles, diet, among others. However, it is most likely a multifactorial condition where protective factors contribute individually to some extent. The gut microbiota (GM) has emerged as a potential factor associated with the establishment of a favorable health phenotype that allows for extreme longevity, as seen in centenarians. To understand the possible impact generated by the GM, its changes, and the probable causes for successful aging, the aim of this review was to synthesize evidence on the role of the GM as a potential protective factor for achieving extreme longevity, using its relationship with centenarians.

Adverse Lipid Profiles Are Associated With Lower Dementia Risk in Older People.

OBJECTIVE: Midlife dyslipidemia is associated with higher risk of dementia in late-life dementia, but the impact of late-life dyslipidemia on dementia risk is uncertain. This may be due to the large heterogeneity in cholesterol measures and study designs employed. We used detailed data from a large prospective cohort of older persons to comprehensively assess the relation between a broad range of cholesterol measures and incident dementia, addressing potential biases, confounders, and modifiers. DESIGN: Post hoc observational analysis based on data from a dementia prevention trial (PreDIVA). SETTING AND PARTICIPANTS: 3392 community-dwelling individuals, without dementia, aged 70-78 years at baseline (recruited between June 2006 and March 2009). METHODS: Total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, and apolipoprotein A1 and B were assessed. Over a median of 6.7 years' follow-up, dementia was established by clinical diagnosis confirmed by independent outcome adjudication. Hazard ratios (HRs) for dementia and mortality were calculated using Cox regression. RESULTS: Dementia occurred in 231 (7%) participants. One-SD increase in LDL/HDL conveyed a 19% (P = .01) lower dementia risk and a 10% (P = .02) lower risk of dementia/mortality combined. This was independent of age, cardiovascular risk factors, cognitive function, apolipoprotein E genotype, and cholesterol-lowering drugs (CLD). This association was not influenced by the competing risk of mortality. Consistent and significant interactions suggested these associations were predominant in individuals with low body mass index (BMI) and higher education. CONCLUSIONS AND IMPLICATIONS: Dyslipidemia in older individuals was associated with a lower risk of dementia. Low BMI and higher education level mitigate poor outcomes associated with dyslipidemia. These findings suggest that a different approach may be appropriate for interpreting lipid profiles that are conventionally considered adverse in older adults. Such an approach may aid predicting dementia risk and designing intervention studies aimed at reducing dementia risk in older populations.

[Dietary diversity, anthropometric status and biochemical profile of centenarians of the Nicoya Peninsula, Costa Rica, and their offspring]. / Diversidad dietética, estado antropométrico y perfil bioquímico de centenarios de la Península de Nicoya, Costa Rica, y su descendencia.

BACKGROUND AND OBJECTIVE: Social relationships, physical activity and diet have been proposed as responsible for longevity; however, many of these conditions have changed in modern societies. The objective of this study was to identify if the anthropometric status, biochemical profile and diet of Nicoyan centenarians is different from that of their decency and if the quality and diversity of the diet of these Costa Ricans differs from that of adults from urban areas of the same country. MATERIALS AND METHODS: Anthropometric, biochemical and dietary assessments were carried out on 120 adults residing in the Nicoya Peninsula, including centenarians, their children and grandchildren. The data were analyzed using descriptive and inferential statistics. RESULTS: There is a significantly lower percentage of excess weight, central adiposity and blood lipids in Nicoyan centenarians compared to their children and grandchildren. The consumption of «Dairy¼ and «Other fruits¼ is higher in centenarians than in their descendants. Centenarians showed a higher dietary diversity index (DDI) compared to other age categories, and they also showed a higher DDI and a significantly more diverse diet than the urban population of Costa Rica. CONCLUSION: Nicoyan centenarians presented a better lipid and glycemic profile than their offspring, they have lower weight and a better quality and diversity of diet than their relatives and than adults from the urban area of Costa Rica.

Dietary patterns and intrinsic capacity in older adults: a 6-year prospective cohort study.

OBJECTIVES: Only a few studies have investigated dietary patterns and intrinsic capacity (IC). This study examined the prospective associations between dietary patterns, IC, and IC sub-domains over 6 years in community-dwelling Korean older adults. DESIGN: A prospective cohort study. SETTING AND PARTICIPANTS: Data were obtained from participants aged 70-84 years in the Korean Frailty and Aging Cohort Study (2016-2022). The study population included 665 enrollees at baseline who completed IC and dietary data. METHODS: Dietary data were obtained from baseline surveys of the nutritional sub-cohort using two nonconsecutive 24-hour dietary recalls, and dietary patterns were derived using cluster analysis. IC was constructed by measuring cognitive, locomotor, vitality, sensory, and psychological domains. A generalized estimating equation was used to analyze the longitudinal associations between dietary patterns, IC, and IC sub-domain scores. RESULTS: In total, 665 enrollees were included in the analysis. After adjusting for confounders, in older men, the dietary pattern of cluster 1 (variety of healthy foods and alcohols) compared to that of cluster 2 (rice and kimchi) was positively associated with changes in the IC score (ß = 0.41, 95% confidence interval [CI] = 0.04-0.78). In older women, the dietary pattern of cluster 1 (variety of healthy foods) was positively associated with changes in the IC score (ß = 0.30, 95% CI = 0.02-0.58), IC score group (ß = 0.11, 95% CI = 0.02-0.20), and psychological domain (ß = 0.25, 95% CI = 0.11-0.38) compared to that of cluster 3 (rice, vegetables, and kimchi). CONCLUSIONS: Dietary patterns (variety of healthy foods) were positively associated with changes in IC scores and their sub-domains in older adults.

Unlocking the biochemical secrets of longevity: balancing healthspan and lifespan.

In an era of rising global life expectancies, research focuses on enhancing the quality of extended years. This review examines the link between mitochondrial function and aging, highlighting the importance of healthspan alongside lifespan. This involves significant human and economic challenges, with longer lifespans often accompanied by reduced well-being. Addressing mitochondrial decline, exploring targeted interventions, and understanding the complexities of research models are vital for advancing our knowledge in this field. Additionally, promoting physical exercise and adopting personalized supplementation strategies based on individual needs can contribute to healthy aging. The insights from this Perspective article offer a hopeful outlook for future advances in extending both lifespan and healthspan, aiming to improve the overall quality of life in aging populations.

The link between exposure to violence and psychological distress among middle-aged Muslims in Israel: the role of gender.

Introduction: To date, it is still unclear if exposure to violence affects psychological distress in middle-aged adults and if the effects are gender specific. This age group is of special interest as it is at the onset of the aging process and is often overlooked or understudied in scholarly research. Specifically, targeted research on middle-aged Muslims living in Israel, a unique population exposed to increasing violence, is lacking. Methods: We examined the relationship between exposure to violence and psychological distress in a cohort of 363 middle-aged adults (223 women) from three Muslim villages in northern Israel, collecting data on violence exposure (Screen for Adolescent Violence Exposure (SAVE) questionnaire), psychological distress (Kessler 6 Psychological Distress questionnaire), and other demographic characteristics including education level and socioeconomic status. We used this data to answer two questions: (1) is exposure to violence a predictor of psychological distress in middle-aged Muslims, and (2) does the relationship between exposure and distress differ between men and women? Results: We revealed a positive link between exposure to violence and psychological distress (ß = 0.145, p = 0.017) when controlling for gender, age, education level, and socioeconomic level. Discussion: Despite previous evidence of gender-based differences in this interplay in younger cohorts, we did not find a significant interaction between gender and the violence exposure-psychological distress interplay. Our findings are some of the first to focus on middle-aged individuals and show that both men and women exhibit connections between exposure to violence and psychological distress when considering covariates. This research provides insights that can be used when planning community-wide interventions and treatment schemes to support healthy aging.

Reciprocal and Differential Influences of Mediterranean Diet and Physical Activity on Adiposity in a Cohort of Young and Older than 40 Years Adults.

Translational research has documented the conjoint beneficial relationships between dietary and physical activity habits concerning weight maintenance. However, the precise interplay between diet and exercise impacting body composition remains unclear, challenging personalized interventions. This study aimed to explore potential interactions and effect modifications of these factors affecting the body mass index (BMI) within an online adult cohort. Data from 11,883 NUTRiMDEA cohort participants were analyzed in this cross-sectional study, categorizing individuals by age, sex, and BMI using linear regression models to assess the interactions between lifestyle factors and adiposity. Significant differences emerged in anthropometry, lifestyle, and health-related quality of life (HRQoL) across categories. The combined effect of diet and physical activity had a greater impact on BMI than physical activity or Mediterranean diet adherence alone, with lower BMI as physical activity levels increased (ß: -0.5) and adherence to the Mediterranean diet decreased, where a modification effect between them was identified (ß: -0.28). Participants with lower Mediterranean diet adherence displayed superior BMI when physical activity was low, but when activity levels were higher, their BMI aligned with those with healthier dietary habits. An interaction link between lifestyle factors and BMI was found, showing the differential effects of the Mediterranean diet and physical activity combination concerning adiposity.

Self-neglect as a mediator between family functioning and healthy aging in older adults living alone in rural China: A cross-sectional study.

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.

Psychometric Properties and Measurement Invariance of the Awareness of Age-Related Change Short Form in Older Adult Samples from Taiwan and Germany.

BACKGROUND AND OBJECTIVES: This study examined the psychometric properties and measurement invariance of the 10-item Awareness of Age-Related Change Short Form (AARC-SF) questionnaire in a Chinese-speaking sample of older adults in Taiwan. RESEARCH DESIGN AND METHODS: Data from 292 participants (Mage = 77.64 years) in the Healthy Aging Longitudinal Study in Taiwan (HALST) cohort were used for Study 1, whereas data from young-old adult samples in Germany were used for Study 2. RESULTS: Study 1 showed that the AARC-SF had satisfactory reliability and validity for assessing adults' AARC in Taiwan. Analyses confirmed the two-factor structure of AARC-gains and AARC-losses. Study 2 demonstrated strong measurement invariance across men and women, whereas direct comparisons of the item scores between young-old adults and old-old adults need to be made with caution. Non-invariance of loadings indicated that certain items were more closely linked to AARC-gains and AARC-losses in Taiwan than in Germany. Non-invariance of intercepts suggested potential biases in comparing item scores between Taiwanese and German older adults. DISCUSSION AND IMPLICATIONS: The AARC-SF emerged as a reliable and valid instrument for capturing positive and negative subjective aging experiences among Taiwanese older adults. However, it is noteworthy that some items on the AARC-SF may solicit different responses from individuals of different ages and different countries of origin, requiring caution with age group and cross-cultural comparisons.

A Most Significant Change evaluation of a new co-designed tool to measure holistic well-being in consumers of community aged care services.

OBJECTIVES: To evaluate a Wellbeing Check-in tool and process for use with BlueCare's home care package (HCP) clients by care and well-being practitioners. The tool had been co-designed with HCP clients and trialled with 15 clients. METHODS: The Most Significant Change (MSC) methodology was used to gather stories from five practitioners, five HCP staff and seven clients. A workshop with senior staff was held to determine themes and whether the tool met its aims. RESULTS: Out of 22 MSC stories, 18 were judged in scope by workshop participants. Eight themes were then identified. Four themes reflected the content of the narratives (i.e. what was discussed): Isolation and connection; Grief; Faith/explicit spirituality; and Client preference. The other four themes reflected the process (i.e. what the discussions meant to participants): Being there/Meaningful conversations; Impact on significant others; New insight; and Purpose of the check-in. These eight themes largely reflected the aims of the Wellbeing Check-in tool in terms of providing a means to optimise connectedness, well-being and spiritual care in accordance with the client's needs, goals and preferences. Unanticipated findings included its benefits for family members and uncertainty about the aim or value of the tool, which highlighted the need for BlueCare to be clear about the purpose of the tool in promoting it to clients and their informal carers. CONCLUSIONS: The Wellbeing Check-in tool was found to be fit for purpose. A tool used flexibly to prompt discussion about well-being can be helpful to clients and pastoral care staff.

Analysis of the life course effects of the disability dilemma among rural older adults in China.

Objective: To analyse whether the accumulation of early adverse experiences among individuals of different generations has an impact on disabilities and evaluate the cumulative effects of disadvantages in rural older adults in China. Methods: A Binary Logit Model was used to analyse the life course effects of the disability dilemma among rural older adults. Results: Regarding Activities of Daily Life (ADLs), there was no significant difference between older adults that experienced 1 adverse events and the control group. The probability of older adults experiencing difficulties in 2, 3, 4, or more types of ADLs was 1.486 times, 2.173 times, and 3.048 times higher than that of the control group, respectively. Regarding Instrumental Activities of Daily Life (IADLs), there was no significant difference between the population that experienced 1 or 2 adverse events and the control group. The probability of experiencing difficulties in 3, 4, or more types of IADLs was 1.527 times and 1.937 times higher than that of the control group, respectively. Early adverse events had a cumulative disadvantageous effect on disability in older adults. The longer the duration of adverse experiences, the higher the risk of disability in old age. Education had a significant mitigating effect on health risks. Conclusion: Pay attention to early factors in the life course, strengthen the promotion of health prevention concepts, and pay attention to the moderating and relieving effects of education on health. We should also gradually improve the rural disability care system and family health security capabilities in China's rural areas.

Underlying Mechanisms of the Protective Effects of Lifestyle Factors in the Prevention of Age-Related Diseases.

The rise in life expectancy has significantly increased the occurrence of age-related chronic diseases, leading to escalating expenses for both society and individuals. Among the main factors influencing health and lifespan, lifestyle takes a forefront position. Specifically, nutrition, mental activity, and physical exercise influence the molecular and functional mechanisms that contribute to the prevention of major age-related diseases. Gaining deeper insights into the mechanisms that drive the positive effects of healthy lifestyles is valuable for creating interventions to prevent or postpone the development of chronic degenerative diseases. This review summarizes the main mechanisms that underlie the positive effect of lifestyle factors in counteracting the major age-related diseases involving brain health, musculoskeletal function, cancer, frailty, and cardiovascular diseases, among others. This knowledge will help to identify high-risk populations for targeted intervention trials and discover new biomarkers associated with healthy aging.
