BACKGROUND: Social support and social networks have long been postulated to impact health outcomes but their impact on life expectancy and disability in older adults remains poorly quantified. METHODS: As part of the Cardiovascular Health Study, we followed 5,749 adults aged 65 years and older from 4 US field centers for 25 years. We assessed the Lubben social network score [range 0-50] and a social support score [range 0-24] derived from the Interpersonal Support Evaluation List (ISEL-12) in two consecutive years starting at study recruitment. We used remaining years of life (YOL) from study enrollment to death to approximate life expectancy. We defined years of active life (YAL) as the number of study years in which participants lived without any difficulties in activities of daily living. We used compression of disability to reflect the proportion of life lived able (YAL/YOL). We used linear regression to adjust for socio-demographics and comorbidity. RESULTS: The mean (standard deviation [SD]) scores were 32.3 ± 6.8 points for social network score and 8.3 ± 2.4 points for social support score. For every 1-SD increase in social network score, adjusted participant life expectancy was 0.40 years higher (95% CI 0.22-0.58; p

IntroductionBlack students attending predominantly White institutions (PWIs) versus historically Black colleges and universities (HBCUs) report more harmful discrimination and develop worse mental health outcomes, potentially offsetting the established benefits of college for lowering dementia incidence.MethodsBlack participants in two cohorts (the Kaiser Healthy Aging and Diverse Life Experiences [KHANDLE] and the Study of Healthy Aging in African Americans [STAR]) who had attended college (N = 716) self-reported the college name (classified as HBCU vs. PWI) and completed three waves of executive function (EF) and verbal episodic memory (VEM) assessments. HBCU effects on cognitive level and decline were estimated using adjusted linear mixed-effects models.ResultsHBCU (vs. PWI) attendees averaged better EF (β = 0.05 [-0.22, 0.32]) and VEM (β = 0.21 [-0.06, 0.46]) at age 70 though neither association was statistically significant. HBCU attendance was associated with slightly faster VEM decline (β = -0.03 [-0.05, 0.00]).DiscussionHarmonized analyses with larger studies are needed to estimate important effects of HBCU attendance.HighlightsHigher education is robustly linked to lower dementia risk, yet Black-White inequities persist among college-educated adults. Black students attending predominantly White institutions (PWIs) versus historically Black colleges and universities (HBCUs) report more harmful discrimination and develop worse mental health outcomes, which may offset the established benefits of college for lowering dementia incidence. HBCU (vs. non-HBCU) attendees averaged better executive function and verbal episodic memory (VEM) at average age 70, though confidence intervals were wide and associations were not statistically significant, and averaged slightly faster decline in VEM. Harmonized analyses using larger nationally representative studies are likely needed to avoid underestimating the health effects of HBCU attendance.

ObjectiveThe goal of this study was to examine if mental health and psychosocial well-being differed between middle-aged (MA; 40-59 years), younger-old (YO; 60-79 years), and older-old (OO; 80+ years) adults with respect to their trends, heterogeneity, and correlates.MethodsEighteen mental health and psychosocial well-being instruments were administered to 590 adults over age 40. Cross-sectional data also included self-report-based measures of sociodemographics, cognitive functioning, physical health and activity, and body mass index.ResultsAge trends across instruments varied in magnitude and shape, but generally supported an inverted U-shaped trend in mental health and psychosocial well-being, with small increases from MA to YO age (d = 0.29) and smaller declines from YO to OO age (d = -0.17). A U-shaped association between age and mental health heterogeneity was also observed. The strongest correlates of mental health and psychosocial well-being differed by age (MA: perceived stress; YO: successful aging; OO: compassion toward others), as did the associations of a flourishing versus languishing mental health and well-being profile.ConclusionsOur findings support the "paradox of aging," whereby declines in physical and cognitive health co-occur with relatively preserved mental health and well-being. Our findings indicate that variance in mental and psychosocial health does not increase linearly with age and support careful consideration of heterogeneity in mental health and aging research. Our findings also suggest that mental health and psychosocial well-being decouple from stress-related dimensions in MA and become increasingly associated with positive, other-oriented emotions in OO, broadly supporting socioemotional theories of aging.

IntroductionChina is facing the challenge of “deep aging”, and promoting healthy aging has become a key research topic. Both medical care and physical exercise are important for health, but while medical services focus on treating illness, physical fitness activities focus on prevention, making them a more effective approach for promoting healthy aging.MethodsThis study uses data from the China Health and Retirement Longitudinal Study (CHARLS), focusing on individuals aged 60 to 80, to investigate the relationship between physical fitness activities and medical expenditures. A Tobit model was employed to analyze the data.Results(1) Active participation in physical fitness activities significantly improves the health of older adults, making physical activity an essential pathway to achieve healthy aging. (2) Participation in sports and fitness activities leads to a crowding-out effect on medical expenditures, significantly reducing healthcare costs for participants. (3) High-intensity physical activities are most suitable for individuals aged 60-65, moderate-intensity activities for those aged 66-70, and low-intensity activities for those aged 71–80.Discussion(1) Policies should focus on raising awareness of physical fitness benefits among older adults, encouraging regular physical activity to improve health and reduce medical costs. (2) A shift from treatment to prevention in health management is needed, promoting exercise as a cost-effective way to reduce healthcare spending. (3) Age-specific fitness guidelines should be developed to provide tailored exercise recommendations for different older aldult age groups.

Decelerating motor decline is important for promoting healthy aging in the elderly population. Acorus tatarinowii Schott is a traditional Chinese medicine that contains β-asarone as a pharmacologically active constituent. We found that β-asarone can decelerate motor decline in various age groups of Caenorhabditis elegans, while concurrently prolonging their lifespan and modulating synaptic transmission. To understand the mechanisms of its efficacy in motor improvement, we investigated and discovered that mitochondrial fragmentation, a marker for aging, is delayed after β-asarone treatment. Moreover, their efficacy is blocked by dysfunctional mitochondria. Corresponding to their role in regulating mitochondrial homeostasis, we found that SKN-1/Nrf2 and GST-4 are critical in the β-asarone treatment, and they appear to be activated via the insulin/IGF-1 signaling pathway. Well-developed intestinal microvilli are required for this process. Our study demonstrates the efficacy and mechanism of β-asarone treatment in age-related motor decline, contributing to the discovery of drugs for achieving healthy aging.

Objective: to understand the feelings and recognitions of older adults when they experience the use of smartphones in everyday life, as well as the implications for the healthy aging process. Method: qualitative research, using the Unified Theory of Acceptance and Use of Technology; the Senior Technology Acceptance & Adoption Model and the methodological framework of Constructivist Grounded Theory. We intentionally recruited people aged 60+; smartphone users; participants for 6 months or more in an extension project, without cognitive impairment, determined by theoretical sampling. A semi-structured script guided data collection. Constant and concomitant comparative analysis followed the steps of initial and focused coding, supported by memos, until theoretical saturation. The Sankey diagram was used to analyze the data, using Atlas.ti software. Results: 37 participants were allocated to two sample groups. We present the category “Experiencing technological evolution during the aging process” and two subcategories: “Experiencing feelings when aging in the face of technological development”; “Using the smartphone and recognizing new experiences”. Conclusion: when experiencing the use of smartphones, older adult understand and recognize the search for digital skills based on their need for usefulness and applicability of information and communication technology in their daily lives, integrating it into the healthy ageing process.

ObjectiveThis study aimed to assess the prevalence of physical activity and its association with the progression of difficulty performing activities of daily living among older adults in China.MethodsA population-based prospective cohort study based on China Family Panel Studies (CFPS) data was conducted in 2018 and 2020. This study used a logistic model to empirically estimate the effects on daily living activities among older adults.ResultsA total of 2073 older adults aged 60 years and above were included, 78.0% of whom did not exercise. The logistic regression model revealed several predictive factors for activity of daily living decline among older adults. These included residence status (OR = 0.672; 95% CI 0.519–0.869; p = 0.002), age (OR = 0.307; 95% CI 0.169–0.557; p

ABSTRACT Respiratory tract infections are the most common triggers for heart failure in elderly people. The healthy respiratory commensal microbiota can prevent invasion by infectious pathogens and decrease the risk of respiratory tract infections. However, upper respiratory tract (URT) microbiome in the elderly is not well understood. To comprehend the profiles of URT microbiota in the elderly, and the link between the microbiome and heart failure, we investigated the oropharyngeal (OP) microbiome of these populations in Heilongjiang Province, located in the North-East of China, a high-latitude and cold area with a high prevalence of respiratory tract infection and heart failure. Taxonomy-based analysis showed that six dominant phyla were represented in the OP microbial profiles. Compared with young adults, the OP in the elderly exhibited a significantly different microbial community, mainly characterized by highly prevalent Streptococcus, unidentified_Saccharibacteria, Veillonella, unidentified_Pre votellaceae, and Neisseria. While unidentified_Prevotellaceae dominated in the young OP microbiome. There was competition for niche dominance between Streptococcus and member of Prevotellaceae in the OP. Correlation analysis revealed that the abundance of unidentified_Saccharibacteria was positive, while Streptococcus was negatively correlated to age among healthy elderly. The bacterial structure and abundance in the elderly with heart failure were much like healthy controls. Certain changes in microbial diversity indicated the potential OP microbial disorder in heart failure patients. These results presented here identify the respiratory tract core microbiota in high latitude and cold regions, and reveal the robustness of OP microbiome in the aged, supplying the basis for microbiome-targeted interventions.IMPORTANCETo date, we still lack available data on the oropharyngeal (OP) microbial communities in healthy populations, especially the elderly, in high latitude and cold regions. A better understanding of the significantly changed respiratory tract microbiota in aging can provide greater insight into characteristics of longevity and age-related diseases. In addition, determining the relationship between heart failure and OP microbiome may provide novel prevention and therapeutic strategies. Here, we compared OP microbiome in different age groups and elderly people with or without heart failure in northeastern China. We found that OP microbial communities are strongly linked to healthy aging. And the disease status of heart failure was not a powerful factor affecting OP microbiome. The findings may provide basic data to reveal respiratory bacterial signatures of individuals in a cold geographic region.

Objectives: Intrinsic capacity impairment results in poor outcomes among older adults. Here we tested handgrip strength as a screening tool for IC impairment in community-dwelling older adults in Xinjiang, China. We assessed the diagnostic accuracy and established optimal cut-off points for handgrip strength in the detection of intrinsic capacity impairment. Methods: In total, 1072 participants were included using a multilevel random sampling method. Intrinsic capacity was constructed according to the definition of the Integrated Care for Older People screening tool proposed by the WHO. Results: Altogether, 73.4 % (787/1072) participants had intrinsic capacity impairment. The prevalence of intrinsic capacity impairment for hearing, vision, mobility, cognition, psychological, and vitality domains was 8.6 %, 4.8 %, 39.6 %, 47.3 %, 12.0 %, and 18.8 %, respectively. The adjusted odds ratios [95 % confidence interval) for handgrip strength was 0.935 [0.914–0.956]. The area under the curve of the receiver operating characteristic curve for handgrip strength of older men, and handgrip strength of older women with intrinsic capacity impairment were 0.7278, and 0.7534, respectively. The handgrip strength cut-off points were 28.47 kg (60–69 years), 25.76 kg (70–79 years), and 24.45 kg (≥80 years) for men, and 20.75 kg (60–69 years), 19.90 kg (70–79 years), and 16.17 kg (≥80 years) for women. Conclusions: Handgrip strength can be used as a convenient tool for evaluating intrinsic capacity. Weak handgrip strength and low education level were associated with intrinsic capacity impairment in community-dwelling older adults in Xinjiang. Using the cut-off points of handgrip strength for different age groups and genders, older adults with impaired intrinsic capacity can be identified, which may reduce the occurrence of adverse outcomes.

Normal aging presents subtle cognitive changes that can be detected before meeting the criteria for Mild cognitive impairment (MCI). Older people with low cognitive reserve and who receive limited cognitive stimulation are at greater risk of deterioration. In this regard, cognitive stimulation (CS) has been identified as an intervention that reduces this risk, provided that its design takes into account the differences in the level of cognitive reserve (CR) acquired throughout life and the baseline level of cognitive functioning. The general objective of this study is to evaluate, through a randomized clinical trial, the effectiveness of a computerized cognitive stimulation program, designed and adapted from Occupational Therapy based on the level of cognitive reserve in older adults in Primary Care. 100 participants will be randomized in a stratified manner according to the level of cognitive reserve (low/moderate/high), assigning 50 participants to the control group and 50 participants to the intervention group. The intervention group will carry out a computerized cognitive stimulation intervention designed and adapted from occupational therapy according to the level of cognitive reserve, through the “stimulus” platform. The main result expected to be achieved is the improvement of higher brain functions. As secondary results, we expect that those cognitive aspects most vulnerable to aging will decrease more slowly (in areas such as memory, executive function, attention and processing speed), and that the cognitive reserve of the participants will increase, in addition to being able to balance gender differences in these aspects. We think that these results can have a positive impact on the creation of adapted, meaningful and stimulating CS programs in older adults to prevent MCI and experience healthier aging.

Background: Functional disability, defined as acquired difficulty in performing basic daily tasks or more complex tasks needed for independent living. Functional assessment among community dwelling elderly is critical due to the changes taking place during the normal aging process, acute illness, worsening chronic illness, and hospitalization which compromises their performances necessary to live independently. Measuring their functional ability can provide objective data to assist with targeting individualized care plan for older adults being the highest consumers of medications due to greater burden of medical conditions in addition to being vulnerable to the effects of medications. It is crucial for the pharmacists to be aware of the geriatric functional disability as pharmacies are often the first point-of-care this elderly group may encounter in community settings. Methods: This study was conducted to estimate the prevalence of functional disability and the common difficulties in the daily task performance among elderly from a state in the Northern region of Malaysia. Besides, the differences in terms of functional disability in both genders were also explored. Among a total of 266 elderly participants. Results: Around 42 % was estimated to face at least one difficulty with Activities of Daily Living while more than half, 57 %, had at least one difficulty with Instrumental Activities of Daily Living. The most common difficulties reported with Activities of Daily Living and Instrumental Activities of Daily Living were transferring (22 %) and transportation (33 %), respectively. Conclusion: In order to deliver effective pharmaceutical care plan emphatically, both senior-friendly pharmacy curricula and pharmacy settings are imperative to address the most common difficulties faced by this vulnerable group.

BackgroundThe emergence of an aging society and the digital age makes healthy aging a hot topic in Chinese society. This paper explores the associations between digital literacy and the subjective health of older adult individuals in PR China, offering insights that May assist policymakers and service providers in developing strategies and interventions suited to the digital era, potentially enhancing the healthy aging process for this demographic in China.MethodsThis study utilized data from the China Longitudinal Aging Social Survey. Initially, demographic variables of 2086 individuals in the sample were analyzed. Subjective health differences among different populations and correlations between core variables were examined. Subsequently, multivariate linear regression and chain mediation methods were utilized to examine the relationships and potential pathways among the three dimensions of digital literacy and the subjective health of older adult individuals.Results(1) The subjective health status of older adult individuals in China was generally favorable, with an average score of 3.406 ± 0.764. (2) There was no direct correlation observed between the frequency of digital information use and the subjective health of the older adult (b = −0.032, p > 0.1). Digital entertainment information (b = 0.294, p > 0.1) did not show a significant effect, whereas life management information (b = 0.437, p

Aging populations face significant cognitive challenges, particularly in working memory (WM). Transcranial alternating current stimulation (tACS) offer promising avenues for cognitive enhancement, especially when inspired by brain physiology. This study (NCT04986787) explores the effect of multifocal tACS on WM performance in healthy older adults, focusing on fronto-parietal network modulation. Individualized physiology-inspired tACS applied to the fronto-parietal network was investigated in two blinded cross-over experiments. The first experiment involved monofocal/bifocal theta-tACS to the fronto-parietal network, while in the second experiment cross-frequency theta-gamma interactions between these regions were explored. Participants have done online WM tasks under the stimulation conditions. Network connectivity was assessed via rs-fMRI and multichannel electroencephalography. Prefrontal monofocal theta tACS modestly improved WM accuracy over sham (d = 0.30). Fronto-parietal stimulation enhanced WM task processing speed, with the strongest effects for bifocal in-phase theta tACS (d = 0.41). Cross-frequency stimulations modestly boosted processing speed with or without impairing task accuracy depending on the stimulation protocol. This research adds to the understanding of physiology-inspired brain stimulation for cognitive enhancement in older subjects.

BackgroundUntreated hearing loss has an effect on cognition. It is hypothesized that the additional processing required to compensate for the sensory loss affects the cognitive resources available for other tasks and that this could be mitigated by a hearing device.MethodsThe impact on cognition of cochlear implants (CIs) was tested in 100 subjects, ≥60 years old, with bilateral moderately-severe to profound post linguistic deafness using hearing aids. Data was compared pre and 12 and 18 months after cochlear implantation for the speech spatial qualities questionnaire, Mini Mental State Examination (MMSE), Trail making test B (TMTB) and digit symbol coding (DSC) from the Wechsler Adult Intelligence Scale version IV and finally the timed up and go test (TUG). Subjects were divided into young old (60–64), middle old (65–75) and old old (75+) groups. Cognitive test scores and times were standardized according to available normative data.ResultsHearing significantly improved pre- to post-operatively across all age groups. There was no change post-implant in outcomes for TMTB, TUG or MMSE tests. Age-corrected values were within normal expectations for all age groups for the TUG and MMSE. However, DSC scores and TMTB times were worse than normal. There was a significant increase in DSC scores between baseline and 12-months for 60- to 64-year-olds (t[153] = 2.608, p = 0.027), which remained at 18 months (t[153] = 2.663, p = 0.023).DiscussionThe improved attention and processing speed in the youngest age group may be a consequence of reallocation of cognitive resources away from auditory processing due to greatly improved hearing. The oldest age group of participants had cognition scores closest to normal values, suggesting that only the most able older seniors tend to come forward for a CI. Severe to profoundly deaf individuals with hearing aids or cochlear implants were still poorer than age-equivalent normally hearing individuals with respect to cognitive flexibility, attention, working memory, processing speed and visuoperceptual functions. Due to a lack of data for the TUG, TMTB and DSC in the literature for hearing impaired individuals, the results reported here provide an important set of reference data for use in future research.

Background: Conventional approaches to frailty assessment rely on in-person evaluation by health professionals in medical settings. The COVID-19 pandemic drastically limited access to both primary care and face-to-face appointments, highlighting a need for novel and forward-thinking frailty screening methods to bridge this gap. Community-based seniors-serving organizations are well-positioned to implement remote frailty assessment, given its potential to enhance virtual services and referrals. Methods: The Clinical Frailty Scale (CFS) was adapted and implemented as Virtual Frailty Screening (VFS), using the Plan-Do-Study-Act (PDSA) framework, in an inner-city organization for older adults. Participants participated in phone assessments by social workers (SWs); in-person visits included the CFS for comparative purposes. As a component of our larger quality improvement initiative, pilot data were analyzed descriptively alongside inferential methods consisting of Kendall's τb, Χ2-test of association, and Wilcoxon matched-pairs signed-rank test. Results: Over 101 older adults were screened, with 79.21 % being assigned as very mild to moderately frail. VFS usage enabled crucial referrals for 70 older adults to receive long-term frailty-specific support and services in the community. Analysis found that the VFS performed similarly to the CFS, established by high convergent validity and alignment between both scales. Conclusions: Findings support the implementation of remote frailty assessment by SWs in community-based seniors serving organizations. This integration bridges immediate service gaps, introducing a transformative approach to frailty assessment which has the potential for scalability. Success was attributed to a multidisciplinary approach with rapid PDSA changes in a nimble organization.

Background: Given the established association between sarcopenia and cognitive impairment was mainly in the older and oldest-old population or people with relatively limited education, this study extends the investigation to community-dwelling middle-to-old age adults in urban communities, emphasizing the need for preventive intervention for muscle health and healthy longevity. Methods: Data of 712 participants from the Gan-Dau Healthy Longevity Plan were retrieved for analysis, and all participants were stratified by age (50–64, 65–74 and 75+ years old). Possible sarcopenia was defined by 2019 consensus report of the Asian Working Group for Sarcopenia (AWGS). This study used four neuropsychological tests for analysis, i.e., Mini-Mental Status Examination (MMSE), California Verbal Learning Test II (CVLT-SF), Digital Symbol Substitution Test (DSST) and Verbal fluency (VF) for global and domain-specific cognitive function. Multivariate generalized linear models (GLMs) were employed to investigate the associations between possible sarcopenia and cognitive function in each age-specific groups. Results: The prevalence of possible sarcopenia increased with age, with 31.8 %, 37.7 %, and 55.6 % in participants aged 5064, 65–74 and, 75+ years, respectively. On the other hand, cognitive performance declined with age. In particular, among participants aged 75+ years with possible sarcopenia, their cognitive performance were poorer than robust counterparts, including MMSE (26.6 [3.4] vs. 27.4 [2.6]), CVTL-SF (total score: 21.5 [5.4] vs. 23.8 [5.5]; 30-second delayed recall: 6.0 [1.7] vs. 6.5 [1.6]), DSST (32.8 [14.3] vs. 41.3 [18.7]), and VF (12.8 [5.1] vs. 14.8 [4.9]). Multivariate generalized linear model indicated that possible sarcopenia was associated with lower MMSE (β: −0.70, p = 0.014) and lower DSST (β: −7.00, p = 0.010) in those aged 50–64 years. Moreover, possible sarcopenia was associated with lower CVLT-SF (total score β:-1.90, p = 0.028), lower DSST (β: −6.45, p

We determined the prevalence and correlates of insufficient physical activity and high sedentary behavior among a nationally representative sample of 2,240 older adults (≥60 years) in Singapore. The Global Physical Activity Questionnaire, administered through face-to-face interviews, assessed physical activity and sedentary behavior. Logistic regression identified the correlates of insufficient physical activity (<600 metabolic equivalent of task minutes/week) and high sedentary behavior (>7 hr/day). The prevalence of insufficient physical activity and high sedentary behavior was 33.7% and 17.3%, respectively. Those older, females, Malays, residing in smaller housing, living with child but no spouse, with functional limitations and sensory impairments (vision/hearing) were more likely to have insufficient physical activity whereas those with tertiary education had lower odds. High sedentary behavior was more likely among those older, with secondary education, preobesity/obesity, and with functional limitations. While policies should encourage all older adults to be physically active, at-risk subgroups identified in our study merit greater attention. [ABSTRACT FROM AUTHOR]

Despite health benefits gained from physical activity and sport participation, older adults are less likely to be active. This study investigates what influences 50- to 75-year-olds (N = 439) to initiate and maintain walking football, across gender, socioeconomic status, number of health conditions, and physical activity level. It also considers relationships between participant characteristics and influences, and intentions to play after a forced break (COVID-19). Results of a U.K. online cross-sectional survey found those with two or more health conditions rated social influences significantly higher in initiation and maintenance than participants with no health conditions. Multiple regression analysis found a positive walking football culture, and perceived use of maintenance resources contributed significantly to intentions to return to play after COVID-19 restrictions eased. Practitioners should consider providing opportunities for social connection, foster a positive walking football culture, and encourage players to utilize maintenance resources (e.g., scheduling sessions) in older adult walking football sessions.

Familiar music facilitates memory retrieval in adults with dementia. However, mechanisms behind this effect, and its generality, are unclear because of a lack of parallel work in healthy aging. Exposure to familiar music enhances spontaneous recall of memories directly cued by the music, but it is unknown whether such effects extend to deliberate recall more generally - e.g., to memories not directly linked to the music being played. It is also unclear whether familiar music boosts recall of specific episodes versus more generalised semantic memories, or whether effects are driven by domain-general mechanisms (e.g., improved mood). In a registered report study, we examined effects of familiar music on deliberate recall in healthy adults ages 65-80 years (N = 75) by presenting familiar music from earlier in life, unfamiliar music, and non-musical audio clips across three sessions. After each clip, we assessed free recall of remote memories for pre-selected events. Contrary to our hypotheses, we found no effects of music exposure on recall of prompted events, though familiar music evoked spontaneous memories most often. These results suggest that effects of familiar music on recall may be limited to memories specifically evoked in response to the music (Preprint and registered report protocol at https://osf.io/kjnwd/).

Abstract Background The objective of this research is to investigate the dynamic developmental trends between Age-Friendly Environments (AFE) and healthy aging in the Chinese population. Methods This study focused on a sample of 11,770 participants from the CHARLS and utilized the ATHLOS Healthy Aging Index to assess the level of healthy aging among the Chinese population. Linear mixed model (LMM) was used to explore the relationship between AFE and healthy aging. Furthermore, a cross-lagged panel model (CLPM) and a random-intercept cross-lagged panel model (RI-CLPM) were used to examine the dynamic developmental trends of healthy aging, taking into account both Between-Person effects and Within-Person effects. Results The results from LMM showed a positive correlation between AFE and healthy aging (β = 0.087, p

Abstract Background This study aimed to examine within-subject differences in levels of physical activity (PA) and sedentary behavior (SB) among Flemish grandparents aged 50 years and older during a day of providing versus not providing grandchild care. Additionally, grandparents’ PA and SB levels of the specific caregiving moment within the included care day were also compared with those of the corresponding specific time frame on the matching non-care day. Methods Data were obtained and pooled from three assessment time points of the Healthy Grandparenting Project. Objectively measured PA and SB levels were assessed through ActiGraphs wGT3x(+) worn during waking hours for seven consecutive days and expressed relative to the total wear time of the selected days or moments (i.e., percentage of time per day or per moment). Generalized linear mixed models were used to evaluate the within-subject differences in grandparents’ light intensity PA (LIPA), moderate-to-vigorous intensity PA (MVPA) and SB levels between a care and non-care day as well as between the care and non-care moment of those respective days. Results A total of 92 grandparents (64.6 ± 4.8 years, 67.4% women) were included in the analyses. During the care day and care moment, grandparents showed higher relative levels of LIPA (∆=4.0% and ∆=7.9%, respectively) and lower relative levels of SB (∆=3.7% and ∆=6.7%, respectively) as compared to their respective non-care day and non-care moment (all p

Abstract Background White matter hyperintensities (WMHs) are often measured globally, but spatial patterns of WMHs could underlie different risk factors and neuropathological and clinical correlates. We investigated the spatial heterogeneity of WMHs and their association with comorbidities, Alzheimer’s disease (AD) risk factors, and cognition. Methods In this cross-sectional study, we studied 171 cognitively unimpaired (CU; median age: 65 years, range: 50 to 89) and 51 mildly cognitively impaired (MCI; median age: 72, range: 53 to 89) individuals with available amyloid (18F-flutementamol) PET and FLAIR-weighted images. Comorbidities were assessed using the Cumulative Illness Rating Scale (CIRS). Each participant’s white matter was segmented into 38 parcels, and WMH volume was calculated in each parcel. Correlated principal component analysis was applied to the parceled WMH data to determine patterns of WMH covariation. Adjusted and unadjusted linear regression models were used to investigate associations of component scores with comorbidities and AD-related factors. Using multiple linear regression, we tested whether WMH component scores predicted cognitive performance. Results Principal component analysis identified four WMH components that broadly describe FLAIR signal hyperintensities in posterior, periventricular, and deep white matter regions, as well as basal ganglia and thalamic structures. In CU individuals, hypertension was associated with all patterns except the periventricular component. MCI individuals showed more diverse associations. The posterior and deep components were associated with renal disorders, the periventricular component was associated with increased amyloid, and the subcortical gray matter structures was associated with sleep disorders, endocrine/metabolic disorders, and increased amyloid. In the combined sample (CU + MCI), the main effects of WMH components were not associated with cognition but predicted poorer episodic memory performance in the presence of increased amyloid. No interaction between hypertension and the number of comorbidities on component scores was observed. Conclusion Our study underscores the significance of understanding the regional distribution patterns of WMHs and the valuable insights that risk factors can offer regarding their underlying causes. Moreover, patterns of hyperintensities in periventricular regions and deep gray matter structures may have more pronounced cognitive implications, especially when amyloid pathology is also present.

Nutrition is a variable risk factor that may be associated with aging. As individuals age, they may experience various nutritional deficiencies and health issues related to inadequate and excessive nutrition. These can include problems with the musculoskeletal system, diminished immune function, metabolic disorders, and cognitive decline. The World Health Organisation has developed a model of healthy aging that focuses on optimizing many aspects of individuals’ intrinsic ability, such as cognition, psychological well-being, sensory function, vitality, and movement. Milk and dairy foods have the potential to help prevent physical and cognitive decline. Milk and dairy foods play a crucial role in providing a variety of essential nutrients, especially during specific stages of life. Dairy products have a significant opportunity to play a vital role in reducing geriatric malnutrition and the loss of muscle mass, bone strength, and functionality. This review aims to comprehensively analyze the potential health benefits of milk and dairy foods. By examining the evidence of associations between these products and the reduction in the incidence of chronic diseases, this study highlights the potential for older adults to lead longer and healthier lives.

Against a background of worldwide demographic change typified by a considerable increase in elderly individuals, open-access publishing in aging, anti-aging, and geriatrics is addressed. The value of improving scientific understanding in various domains is emphasized, as is the necessity for accessible, rapidly spread knowledge to tackle the multiple difficulties posed by aging populations. The rise of open-access publishing is viewed as an innovative trend that lowers barriers to access and promotes interdisciplinary collaboration. The advantages of open access in aging research are discussed, focusing on promoting worldwide collaboration, improving visibility and citation rates, and expediting the translation of research into practical applications. Given the expanding global aged population, the article emphasizes the urgent need for extensive research and the development of public health policies to promote healthy aging. Open access is praised for its inclusive aspect, which promotes interdisciplinary collaboration and a comprehensive understanding of the aging process. Open access to aging research has a bright future, potentially expanding our understanding of the aging process, stimulating global collaboration, and influencing data-driven public health solutions. The continued evolution of open access in aging research is distinguished by collaborative efforts, ethical considerations, and a commitment to enhancing the well-being of aging people worldwide. Embracing transparency and inclusivity creates the groundwork for a future in which scientific information informs policies and behaviors that benefit future generations as they age.

Background While edentulism remains a serious public health problem for older adults in Colombia, few analyses have been conducted from the framework of active aging as a part of the positive discourse of aging. This study analyzed complete edentulism and its relationship with determinants including personal, behavioral, and health systems and social services. Methods This study included a total of 19,004 older adults. We used univariate, bivariate, and multivariate logistic regression type scores to investigate the relationships between the variables. The personal determinants included basic (Barthel scale) and instrumental activities of daily living (Lawton scale), public transportation, functional limitations, self-perceived health, and health problems. The behavioral factors included alcohol and tobacco use, mini nutritional tests, and physical activity. The last determinant was the healthcare system, while social services access included dental services. The analysis also included sociodemographic variables. Results The results revealed significant associations for the variables of the three determinants, including the risk of malnutrition (odds ratio [OR]=1.15), functional limitation (OR=1.15), moderate physical activity (OR=1.08), and access to dental services (OR=2.31). Sex, years of education, and race were also risk factors, among other variables. Personal determinants, behavior, and use and access to health services were related to edentulism in older adults. Conclusion These findings support the need to include different analyses of edentulism from multicausality and to understand the oral cavity and the living conditions of aging adults.

Abstract Background With one in five individuals aged 65 or older living with type 2 diabetes worldwide, it is crucial to acknowledge and address the challenges faced by this population. In this context, our study aims to evaluate the efficacy of a behavioral intervention model delivered through a smart speaker on mental health and diabetes self-care in the elderly with diabetes. Methods This is a single-center, pragmatic, parallel two-arm open randomized clinical trial involving elderly patients with type 2 diabetes. We plan to enroll a total of 112 individuals who will be randomized 1:1 to receive the Smart Speaker EchoDot 3rd Gen device (Amazon Echo®) for home use (intervention arm) or to maintain usual care (control arm). The primary outcome is mental distress, assessed using the 20-item Self Reporting Questionnaire (SRQ-20) after a 12-week intervention period. Secondary outcomes include quality of life, adherence to diabetes self-care behaviors, perception of stress, glycemic control, blood pressure, and lipid profile. Analysis of covariance (ANCOVA) will be used to evaluate the effects of the intervention on the outcomes. Discussion This study assesses the effectiveness of an interactive virtual assistance system for enhancing mental health and glycemic control among elderly individuals with type 2 diabetes. The findings may introduce smart speakers as a valuable tool for promoting diabetes-related self-care in this population. Trial registration ClinicalTrials.gov NCT05329376. Registered on 15 April 2022. Enrollment began on 20 June 2023 and the last update of protocol was on 13 December 2023.

Abstract Background Life-long health inequalities exert enduring impacts and are governed by social determinants crucial for achieving healthy aging. A fundamental aspect of healthy aging, intrinsic capacity, is the primary focus of this study. Our objective is to evaluate the social inequalities connected with the trajectories of intrinsic capacity, shedding light on the impacts of socioeconomic position, gender, and ethnicity. Methods Our dynamic cohort study was rooted in three waves (2009, 2014, 2017) of the World Health Organization’s Study on Global AGEing and Adult Health in Mexico. We incorporated a nationally representative sample comprising 2722 older Mexican adults aged 50 years and over. Baseline measurements of socioeconomic position, gender, and ethnicity acted as the exposure variables. We evaluated intrinsic capacity across five domains: cognition, psychological, sensory, vitality, and locomotion. The Relative Index of Inequality and Slope Index of Inequality were used to quantify socioeconomic disparities. Results We discerned three distinct intrinsic capacity trajectories: steep decline, moderate decline, and slight increase. Significant disparities based on wealth, educational level, gender, and ethnicity were observed. Older adults with higher wealth and education typically exhibited a trajectory of moderate decrease or slight increase in intrinsic capacity. In stark contrast, women and indigenous individuals were more likely to experience a steeply declining trajectory. Conclusions These findings underscore the pressing need to address social determinants, minimize gender and ethnic discrimination to ensure equal access to resources and opportunities across the lifespan. It is imperative for policies and interventions to prioritize these social determinants in order to promote healthy aging and alleviate health disparities. This approach will ensure that specific demographic groups receive customized support to sustain their intrinsic capacity during their elder years.

Japan has become a super-aged society. To overcome the negative implications of this, practitioners are increasingly using exercise-based interventions to reduce the requirement for long-term care among Japanese older adults. However, no comprehensive means of assessing the wide range of exercise behavioral determinants exists for this population. Thus, the principle aim of this study was to develop a questionnaire based upon the theoretical domains framework—a framework that has synthesized a wide range of behavior change theories. Completed responses were received from 1,000 Japanese older adults who resided in the Kansai area of Japan. Findings were suggestive of good reliability and validity for seven unique psychological determinants of exercise. This study was the first to provide a measurement tool related to a distinct range of psychological determinants of exercise among Japanese older adults. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic has highlighted the challenges of vaccination and the infectious risks among the elderlies. However, immunization rates for recommended vaccines in this population are insufficient in France. We aimed in this study to identify the levers and obstacles to vaccination among seniors, and to establish the arguments that could lead to some new vaccination behaviors. A qualitative survey based on 14 semi-structured interviews was conducted with people aged 65 and over, living at home in the Auvergne Rhône-Alpes region (France) from March to May 2022. The interviews were recorded, entirely transcribed, then subjected to a thematic content analysis. The results show that participants are keen to preserve their health by maintaining their physical capacity, taking regular exercise and eating a balanced diet. However, vaccination was not mentioned as a mean of preventing infectious diseases. Infections were not perceived as a cause for concern. Furthermore, the physical and cognitive consequences of infectious diseases, which could result in a loss of autonomy, were not known. These elements could be a good lever to bring hesitant elderly people to reconsider their position toward vaccination. Vaccines were not seen as a strategy to prevent loss of autonomy among elderlies. Since vaccines against influenza, COVID-19, shingles, pneumococcus have proved to be effective in protecting against cardiovascular events, this argument might be the starting point for a prevention campaign for the elderly.

Older adults often face barriers to obtaining recommended diet, physical activity, and fitness levels. Understanding these patterns can inform effective interventions targeting health beliefs and behavior. This cross-sectional study included a multicultural sample of 58 older adults (aged 55+ years, M=71.98) living in independent senior housing in urban Southcentral Alaska. Participants completed a questionnaire and the Senior Fitness Test that assessed self-reported fruit and vegetable intake, physical activity, self-efficacy, and functional fitness. T-tests and bivariate correlation analyses were used to test six hypotheses. Results indicated that participants had low physical activity but had a mean fruit and vegetable intake that was statistically significantly higher than the hypothesized “low” score. Only 4.26% of participants met functional fitness standards for balance/agility, and 8.51% met standards for lower-body strength. However, 51.1% met standards for upper-body strength and 46.8% met standards for endurance The results also indicated that nutrition self-efficacy and exercise self-efficacy were positively related to fruit and vegetable intake and physical activity levels, respectively. Interestingly, income was not related to nutrition or activity patterns. These data complicate the picture on dietary and physical activity patterns for older adults in Alaska and offer recommendations for future health promotion activities.
