Purpose: To examine the associations of accelerometer-derived steps volume and intensity with hospitalizations and all-cause mortality in older adults. Methods: This prospective cohort study involved 768 community-dwelling Spanish older adults (78.8 § 4.9 years, mean § SD; 53.9% females) from the Toledo Study for Healthy Aging (2012 2017). The number of steps per day and step cadence (steps/min) were derived from a hip-mounted accelerometer worn for at least 4 days at baseline. Participants were followed-up over a mean period of 3.1 years for hospitalization and 5.7 years for all-cause mortality. Cox proportional hazards regression models were used to estimate the individual and joint associations between daily steps and stepping intensity with hospitalizations and all-cause mortality. Results: Included participants walked 5835 § 3445 steps/day (mean § SD) with an intensity of 7.3 § 4.1 steps/min. After adjusting for age, sex, body mass index (BMI), education, income, marital status and comorbidities, higher step count (hazard ratio (HR) = 0.95, 95% confidence inter vals (95%CI: 0.90 1.00, and HR = 0.87, 95%CI: 0.81 0.95 per additional 1000 steps) and higher step intensity (HR = 0.95, 95%CI: 0.91 0.99, and HR = 0.89, 95%CI: 0.84 0.95 per each additional step/min) were associated with fewer hospitalizations and all-cause mortality risk, respectively. Compared to the group having low step volume and intensity, individuals in the group having high step volume and intensity had a lower risk of hospitalization (HR = 0.72, 95%CI: 0.52 0.98) and all-cause mortality (HR = 0.60, 95%CI: 0.37 0.98). Conclusion: Among older adults, both high step volume and step intensity were significantly associated with lower hospitalization and all-cause mortality risk. Increasing step volume and intensity may benefit older people.

Anti-aging products still are a big business worldwide. The most active promoters of anti-aging products currently are internet dealers, the cosmetic and the dairy industry or companies that sell nutritional supplements. Only a few of the advertised substances however have been studied in clinical trials under robust conditions. Several drugs demonstrate positive effects on intracellular mechanisms that are associated with delayed cellular aging. This does not mean that they are in delaying human aging. In contrast, key elements that provide successful healthy and long aging in humans are physical and mental activity a balanced, mediterranean diet and social contacts.

A wide body of literature suggests that transcranial direct current stimulation (tDCS) administered over the prefrontal cortex can improve executive function – including decision-making and inhibitory control – in healthy young adults. However, the effects of tDCS in older adults are largely unknown. Here, using a double-blind, sham-controlled approach, changes in a combined perceptual decision-making and inhibitory control task were assessed before and after the application of tDCS (1 mA, 20 minute) targeting the right inferior frontal gyrus (rIFG) or pre-supplementary motor area (preSMA) in 42 young (18–34 years) and 41 older (60–80 years) healthy adults. Compared to sham stimulation, anodal tDCS over the preSMA improved decision-making speed for both age groups. Furthermore, the inhibitory control performance of older and younger adults was improved by preSMA and rIFG stimulation, respectively. This study provides evidence that tDCS can improve both perceptual decision-making and inhibitory control in healthy older adults, with the causal role of the preSMA and rIFG regions in cognitive control appearing to vary as a function of healthy ageing.

The slowdown, inhibition, or reversal of age-related decline (as a composite of disease, dysfunction, and, ultimately, death) by diet or natural compounds can be defined as dietary geroprotection. While there is no single reliable biomarker to judge the effects of dietary geroprotection, biomarker signatures based on omics (epigenetics, gene expression, microbiome composition) are promising candidates. Recently, omic biomarkers started to supplement established clinical ones such as lipid profiles and inflammatory cytokines. In this review, we focus on human data. We first summarize the current take on genetic biomarkers based on epidemiological studies. However, most of the remaining biomarkers that we describe, whether omics-based or clinical, are related to intervention studies. Then, because of their promising potential in the context of dietary geroprotection, we focus on the effects of berry-based interventions, which up to now have been mostly described employing clinical markers. We provide an aggregation and tabulation of all the recent systematic reviews and meta-analyses that we could find related to this topic. Finally, we present evidence for the importance of the "nutribiography," that is, the influence that an individual's history of diet and natural compound consumption can have on the effects of dietary geroprotection.

Dermatology is often tasked with balancing the clinical appearance of aging skin with the reality of what healthy aging means. In this article, we review some of the core principles of healthy aging and explore common misconceptions, both from patients and physicians, regarding aging. Recognition of the basics of healthy aging and awareness of these aging myths can empower providers to advise patients accurately and productively regarding their aging goals.

Hippocampal neurodegeneration, a primary component of Alzheimer's disease pathology, relates to poor cognition; however, the mechanisms underlying this relationship are not well understood. Using a sample of cognitively normal older adults and individuals with mild cognitive impairment, this study aims to determine the topological properties of functional networks accompanying hippocampal atrophy in aging, along with their association to cognition and clinical progression. We considered two conceptually differing topological properties: redundancy (the existence of alternative channels of functional commutation) and local efficiency (the efficiency of local information exchange). Hippocampal redundancy, but not local efficiency, mediated the association between low hippocampal volume and low memory in both the whole sample and in s-amyloid positive participants. Additionally, participants with high hippocampal volume, redundancy, and memory clustered separately from those with low values on all three measures, with the latter group showing higher conversion rates to dementia within three years. Together, these results demonstrate that reduced hippocampal redundancy is one mechanism through which hippocampal atrophy associates with memory impairment in healthy and pathological aging.

AIM Maintaining ≥20 teeth is a public health goal worldwide. Healthy aging, which includes psychological and social well-being, as well as physical indicators, has attracted a great deal of attention with the progression of aging societies. However, no studies have examined the association between the number of remaining teeth and healthy aging. This study aimed to investigate the association between the number of remaining teeth and healthy aging. METHODS This community-based longitudinal cohort study included 8300 Japanese people aged ≥65 years who were free of disability and depression in the baseline survey in 2006. The participants were categorized into four groups according to the number of remaining teeth at baseline: 0-9, 10-19, 20-24 and ≥25. The primary outcome was healthy aging (defined as meeting all four of the following criteria: free of disability, free of depression, high health-related quality of life and high life satisfaction), as assessed by a questionnaire survey carried out in 2017. Multiple logistic regression was used to calculate the corresponding odds ratios and 95% confidence intervals. RESULTS During about 11 years of follow-up, 621 (7.5%) participants attained healthy aging. Participants with ≥20 remaining teeth showed a higher healthy aging rate. Compared with participants with 0-9 teeth, the multivariate-adjusted odds ratios (95% confidence intervals) for 10-19, 20-24 and ≥25 teeth were 0.98 (0.77-1.26), 1.28 (1.01-1.63) and 1.59 (1.24-2.03), respectively. CONCLUSIONS These findings suggest that maintaining ≥20 teeth was associated with healthy aging. Geriatr Gerontol Int 2021; ••: ••-••.

SUMMARY Aging is a universal feature of life and a complex process at all levels from the biological to the societal. What constitutes older age is subjective and flexible, and how one defines older age is influenced by everchanging individual, generational, and cultural expectations. As the global population ages at an unprecedented rate, we are increasingly confronted with a myriad of challenges associated with aging, including increased healthcare needs and the far-reaching negative consequences of individual and structural agism. However, the shift in world demographics toward an older population is not a growing burden, but an opportunity to reshape our view of older life and proactively embrace healthy aging. Indeed, a healthy person is not defined by the absence of illness, but by the potential for meaningful work, positive relationships, and longevity. Simple preventive measures, such as improved diet and increased exercise, can enhance overall health and quality of life, and growing evidence highlights the potential of positive psychology for improving psychological well-being and overall quality of life. Now more than ever, technological innovation including artificial intelligence can be leveraged to improve our understanding of the causes and consequences of aging, as well as the most effective interventions to enhance resilience and extend healthy longevity. Good health is our greatest asset. It is the responsibility of all-individuals, society, business, science, healthcare systems, and government-to ensure that everyone is well equipped to maintain good health. Together, we can all live better, longer.

Objective: To investigate the associations between linguistic parameters in spontaneous speech at baseline and cognitive impairment and frailty nine years later.Methods: A prospective analysis was carried out on data of the Frailty in Brazilian Older People Study (FIBRA) Study, a population-based study on frailty. From a probabilistic sample of 384 individuals aged 65 and older at baseline (2008–2009), 124 aged 73 years and older at follow-up were selected, as they had scored above the cutoff values of cognitive screening for dementia adjusted by years of schooling at baseline and had answered to the question What is healthy aging and had no frailty at baseline. Verbal responses were submitted to content analysis and had its ideas and words counted. Number of ideas corresponded to the frequency of meaning categories and number of words to all identified significant textual elements in the text constituted by the sample answers to that question.Results: Multivariate logistic regression analyses, controlling for the effects of age, sex, and education, showed that individuals with a high number of ideas at baseline had lower chance of having cognitive impairment (OR = 0.39; 95% CI 0.22 − 0.69) and frailty (OR 0.66; 95% CI 0.44 − 0.99) nine years later than those with low number of ideas.Conclusions: Higher number of ideas, but not number of words, in spontaneous speech seems to be associated to a more positive prognosis in mental and physical health nine years later. Linguistic markers may be used to predict cognitive impairment and frailty in older individuals.

Purpose To explore the physical activity level of community environmental volunteering (CEV) participants and the differences in physical functions and daily activity patterns between the older adults who engaged in intensive CEV (≥15 hours/week) and non-intensive CEV (Design Cross-sectional study. Setting Three recycling stations in Taiwan. Sample In total, 113 community-dwelling older adults who regularly participated in CEV. The response rate was 53%. Measures The ActiGraph wGT3x-BT accelerometer for the percentage of sedentary, light, and moderate to vigorous physical activity (MVPA) of CEV time and awaken time; the Jamar hand dynamometer for grip strength; and the MicroFET3 muscle testing dynamometer for knee extension strength. Analysis Analysis of covariance with the baseline characteristics as covariates. Results Overall, MVPA, light, and sedentary activities accounted for 53.73%, 41.10%, and 5.23% of CEV time, respectively. The intensive group (n = 61) displayed greater dominant handgrip strength ( P = .004) and higher MVPA percentage in daily life ( P = .044) than the non-intensive group (n = 52). Conclusion CEV provides sufficient opportunities for older adults to perform physical activity. Intensive CEV is related to greater handgrip strength but not lower limb strength. Further study is needed to establish the causal relationship between CEV and health variates.

Background Healthy ageing is a complex construct which involves multiple dimensions. Previous studies of healthy ageing have focused only on measuring the intrinsic capacity of the older person. The objectives of this study were to design a multidimensional model of healthy ageing and to identify its determinants from national data in Ecuador. Methods A cross-sectional analytical study was carried out from the National Survey of Health and Well-being of the Older Adult, 2010. Sample was 1797 adults aged 65 years or more. A multidimensional model was designed based on the World Health Organization’s concept of healthy ageing. For the analysis, two groups were created: a healthy ageing and a less healthy ageing group. Bivariate and multivariate logistic regressions were performed to analyze the probability of belonging to the healthy group according to sex, age, area of ​​residence, level of education, perceived health status, perceived life satisfaction, and poverty by income level. Results The 53.15% of the sample was classified in the healthy ageing group. Women and the poorest older adults were less likely to be in the healthy ageing group (OR 0.58; 95% CI 0.464–0.737; OR 0.44; 95% CI 0.343–0.564). Older adults with secondary education or higher, who considered their health as excellent and who were satisfied with their life, had a greater probability of being in healthy ageing group (OR 2.61; 95% CI 1.586–4.309; OR 28.49; 95% CI 3.623–224.02; OR 0.23; 95% CI 0.165–0.341). Conclusions This study contributes with a multidimensional approach to healthy ageing. It proposes to evaluate the intrinsic capacity of the individual, the social and political environment and the interaction with it, through indicators that discriminate who are ageing in a healthy way and who are not. By using this model, it was identified that gender and economic situation seem to play an important role on heathy ageing of the Ecuadorian population. Public policies are necessary to promote healthy ageing, especially focused on improving socioeconomic conditions and gender equity.

A doctrine was established regarding the so called “new beginning” – the transition to the post-retirement period for a full-value experience of the available compensatory reserves and creation of overcoming strategies for opposing and coping with the obstacles in the still uncommon lifestyle of the senior citizen. By outlining the role of physical activity in a synthesized format, a successful attempt for data classification worldwide was made; in one fourth of the elderly people there is insufficient physical activity, more evident in the women and for Bulgaria this percent is higher (95%). The role and effect of categorized physical exercises for mobility, flexibility, and stretching, aerobic and anaerobic movements have been pointed out. Moreover, the review discusses the preventive effects of rehabilitation, including psychological ones and the role of it in helping patients live with socially significant diseases, coping with disability. The contribution of physical activity and rehabilitation as protective factors of non-infectious diseases is associated with good mental health, improved quality of life and well-being. Within this meaning, while contemporary medicine adds years to life, physical activity and mostly rehabilitation is a significant reason for adding a meaningful life in the course of aging and old age.

Background Social isolation is a risk factor for morbidity and mortality comparable to well-established risk factors including smoking, hypertension, and a sedentary lifestyle. The specific biological mechanisms that connect social isolation to morbidity and mortality remain unclear. Interleukin-6 (IL-6) and C-reactive protein (CRP) are biological markers that are upregulated during inflammation and can have long-term negative consequences for the health of individuals as they age. Methods Utilizing Round 7 (2017) data from the National Health and Aging Trends Study (NHATS), we examine the relationship between social isolation and two biological markers: IL-6 and high-sensitivity CRP. This study included a nationally representative sample of 4648 Medicare beneficiaries 65 years and older who provided samples using dried blood spot (DBS) techniques. We defined social isolation utilizing a multi-domained typology that considers living arrangement, core discussion network, religious attendance, and social participation. IL-6 and CRP were obtained via DBS that were collected in Round 7 of the NHATS. We performed linear regression to examine the association between social isolation and biological markers IL-6 and CRP. Results After adjusting for age, gender, race/ethnicity, income, tobacco use, body mass index, and chronic conditions, we found that severe social isolation and social isolation were significantly associated with higher levels of IL-6 and CRP values among older adults. Conclusions Social isolation is associated with higher levels of biological markers (IL-6 and CRP). Our findings inform the pathway between social isolation and morbidity and mortality among older adults. IL-6 or CRP could be a proximal outcome measures for future clinical and social interventions that seek to alter the trajectory of social isolation and its associated health outcomes.

A Social Prescribing Local System (SPLS) can be defined as a set of joined community, health, and social organizations to foster SP-oriented activities. This study aimed to develop and assess the feasibility of an SPLS implemented in a Mediterranean country, to promote health and wellbeing and contribute to active and healthy aging. Methods: A mixed-methods approach was followed, including three sequential components: 1) Cross-sectional online survey targeting health professionals (HP) working in a primary health care cluster, Portugal's southern region; 2) Pilot study implementing an on-the-job training program for HP, designed to meet identified training needs in the survey; 3) Focus group (FG) with the HP who participated in the pilot study, two individual interviews, with an elderly patient and a community provider for assessing the satisfaction with the pilot test. Results: Sixty-five HP completed the survey; of these, 13 completed the theoretical part of the on-the-job training program; and six (out of these 13) completed the full program. Five HP participated in the FG, one patient and one community provider were interviewed. The surveyed HP perceived as facilitators to implement SP: an automatic system of notifications to prompt the use of SP, contribute to patient satisfaction, human and community resources' stability. The survey also highlighted barriers to SP implementation: length of appointments, shortage of human resources, data records confidentiality, low patient adherence rates, bureaucratic issues, time constraints, and financial costs. Participants were satisfied with the training. Identified SPLS implementation benefits were grouped into four dimensions (from the qualitative approach): gains for patients' health and wellbeing, support for the health services, sustainability of the community resources, and HP' professional satisfaction. Conclusions: Our study took the first steps towards the implementation of an SPLS. Findings reinforce that training HP in SP and on-the-job training seems feasible. This approach was well received and appears to represent a suitable and sustainable strategy. It can promote professional satisfaction, support health services, contribute to the stability of community resources, improve health and promote active and healthy aging., This review was funded by the Portuguese Directorate-General of Health through the CENIE project (Fundo Europeu de Desenvolvimento Regional (FEDER), Programa Interreg V-A Espanha-Portugal (POCTEP) 2014/2020.

Purpose The purpose of this study was to determine whether net metabolic cost of walking is affected by age per se. Methods We selected 10 healthy, active older adults (mean age 75 years) and 10 young adults (mean age 26 years), and determined their preferred overground walking speed. On the same day, in a morning and afternoon session, we had them walk at that speed overground and on a treadmill while we measured oxygen consumption rate. From the latter we subtracted the rate in sitting and calculated net metabolic cost. Results Anthropometrics were not different between the groups nor was preferred walking speed (1.27 m s−1 both groups). There was no difference in net metabolic cost of overground walking between older and young adults (e.g., in the morning 2.64 and 2.56 J kg−1 m−1, respectively, p > 0.05). In the morning session, net metabolic cost of walking was higher on the treadmill than overground in our older adults by 0.6 J kg−1 m−1 (p Conclusion First, there is no effect of age per se on metabolic cost of overground walking. Second, older adults tend to have higher metabolic cost of walking on a treadmill than walking overground at preferred speed, and adaptation may take a long time. The commonly reported age-related elevation of metabolic cost of walking may be due to confounding factors causing preferred walking speed to be lower in older adults, and/or due to older adults reacting differently to treadmill walking than young adults.

Multifaceted and divergent manifestations across tissues and cell types have curtailed advances in deciphering the cellular events that accompany advanced age and contribute to morbidities and mortalities. Increase in human lifespan during the past century has heightened awareness of the need to prevent age-associated frailty of neuronal and sensory systems to allow a healthy and productive life. In this review, we discuss molecular and physiological attributes of aging of the retina, with a goal of understanding age-related impairment of visual function. We highlight the epigenome–metabolism nexus and proteostasis as key contributors to retinal aging and discuss lifestyle changes as potential modulators of retinal function. Finally, we deliberate promising intervention strategies for promoting healthy aging of the retina for improved vision.

The World elderly population is expected to double before 2050. Unhealthy habits and unhealthy lifestyles are commonly associated with age-related diseases or their worsening. Modification in daily lifestyle and diet may help preventing age-related diseases onset and efficiently affecting their evolution, thus promoting the Healthy Aging process, concept recently coined to describe the disease-free aging process. This review highlights the role of nutrition science in promoting healthy aging. Since the Mediterranean Model demonstrated to be a useful style in supporting healthy aging, promotion of this correct lifestyle by health policies seems to be the best approach to achieve this target.

We evaluated whether self-reports of worse cognition in older adults with normal cognitive function reflected actual memory decline, amyloid pathology, and subtle vulnerabilities in hippocampal function. We measured subjective cognitive decline (SCD) in 156 older participants from the Dallas Lifespan Brain Study. Functional hippocampal activation during encoding, measured with fMRI, and longitudinal memory change that was measured in the four years preceding the SCD measures were used to predict the magnitude of SCD. A subsample (N=105) also underwent 18F-Florbetapir PET imaging that measured amyloid burden. Results showed that increased SCD were associated with greater prior memory decline and amyloid deposition. Importantly, decreased hippocampal activation during encoding was a significant predictor of SCD, particularly in young-old adults below 69 years old, above and beyond prior memory change and amyloid deposition. These results indicate that multiple measures of neural and cognitive dysfunction are simultaneously associated with SCD. Moreover, SCD in younger seniors appears to reflect deficient hippocampal activity that increases their reports of poorer memory, independent of amyloid.

Aging has been associated with the functional decline of episodic memory (EM). Unanswered questions are whether the decline of EM occurs even during healthy aging and whether this decline is related to amyloid-β (Aβ) deposition in the hippocampus. Objective: The main purpose of this study was to investigate data on the relationship between the age-related EM decline and Aβ deposition. Methods: We searched the Cochrane, MEDLINE, Scopus, and Web of Science databases and reference lists of retrieved articles that were published in the past 10 years. The initial literature search identified 517 studies. After screening the title, abstract, key words, and reference lists, 56 studies met the inclusion criteria. Results: The overall results revealed that increases in Aβ are related to lower hippocampal volume and worse performance on EM tests. The results of this systematic review revealed that high levels of Aβ may be related to EM deficits and the progression to Alzheimer’s disease. Conclusions: We discussed the strengths and pitfalls of various tests and techniques used for investigating EM and Aβ deposition, methodological issues, and potential directions for future research. RESUMO O envelhecimento tem sido associado a um declínio funcional da memória episódica (ME). Algo ainda sem resposta é se o declínio da ME ocorre mesmo no envelhecimento saudável e se esse declínio pode estar relacionado à deposição de Aβ no hipocampo. Objetivo: Nosso objetivo principal foi investigar os dados sobre a relação entre a memória episódica e a deposição de Aβ no envelhecimento saudável. Métodos: Nós buscamos nas bases de dados Cochrane, MEDLINE, Scopus, Web of Science e nas listas de referências dos estudos dos últimos 10 anos. A busca inicial nas bases de dados identificou 517 estudos. Após a triagem de título, resumos, palavras-chave e referências, 56 estudos atenderam aos critérios de inclusão. Resultados: O resultado geral revelou que o aumento de Aβ estava relacionado ao menor volume do hipocampo e pior desempenho em testes de ME. Em resumo, os resultados da presente revisão sistemática revelaram que altos níveis de Aβ podem estar relacionados ao declínio de ME e conversão progressiva para a Doença de Alzheimer. Conclusões: Aqui, discutimos os pontos fortes e as limitações dos testes e técnicas para investigar a deposição ME e Aβ, bem como questões metodológicas e direções futuras.

Master athletes perform high volumes of exercise training yet display lower levels of physical functioning and exercise performance when compared with younger athletes. Several reports in the clinical literature show that long chain n-3 polyunsaturated fatty acid (LC n-3 PUFA) ingestion promotes skeletal muscle anabolism and strength in untrained older persons. There is also evidence that LC n-3 PUFA ingestion improves indices of muscle recovery following damaging exercise in younger persons. These findings suggest that LC n-3 PUFA intake could have an ergogenic effect in master athletes. However, the beneficial effect of LC n-3 PUFA intake on skeletal muscle in response to exercise training in both older and younger persons is inconsistent and, in some cases, generated from low-quality studies or those with a high risk of bias. Other factors such as the choice of placebo and health status of participants also confound interpretation of existing reports. As such, when considered on balance, the available evidence does not indicate that ingestion of LC n-3 PUFAs above current population recommendations (250–500 mg/day; 2 portions of oily fish per week) enhances exercise performance or recovery from exercise training in master athletes. Further work is now needed related to how the dose, duration, and co-ingestion of LC n-3 PUFAs with other nutrients such as amino acids impact the adaptive response to exercise training. This work should also consider how LC n-3 PUFA supplementation may differentially alter the lipid profile of cellular membranes of key regulatory sites such as the sarcolemma, mitochondria, and sarcoplasmic reticulum.

Falls are a major public health problem globally. Each year, 2.8 million elderly people (defined as those aged ≥65) are treated in emergency departments for fall injuries. A questionnaire containing 15 questions, prepared by researchers, was provided to patients who visited the emergency department due to falls and were aged ≥65. Patients who had fallen on the ground were included in the study group and were categorized using the following criteria: age, gender, education, socioeconomic status, life spots, falling location, chronic illnesses, previous falling episodes, cause of falls, medications used, hospital procedures undergone and the outcome of those procedures. A questionnaire was given to 159 patients that visited our emergency department as a result off all. When those patients that did not respond to the questionnaires, those who had high falls, and those who did not remember their traumas were excluded, there were 119 remaining. There were 83 female participants (69.7%) and 79.87 (SD, 7.98) were participants in the study. In our study, 21 (17.6%) patients were identified as having had previous falls. Age, gender, education status, living environment, number of drugs used, diseases and p values were compared according to old operative emoticons: 0.434, 0.855, 0.607, 0.502, 0.778, 0.324and 0.384, and there are no significant statistical differences between them. Despite the challenges mentioned above, educating people about the benefits of healthy ageing, and taking preventive measures will likely help to reduce negative outcomes in the future.

It is well recognized that not all individuals age equivalently, with functional dependence attributable, at least in part, to stress accumulated across the lifespan. Amongst these dependencies are age-related declines in cognitive function, which may be the result of impaired inhibitory processing (e.g., sensory gating). Herein, we examined the unique roles of life and biological stress on somatosensory gating dynamics in 74 adults (22-72 years old). Participants completed a sensory gating paired-pulse electrical stimulation paradigm of the right median nerve during magnetoencephalography (MEG) and data were subjected to advanced oscillatory and time-domain analysis methods. We observed separable mechanisms by which increasing levels of life and biological stress predicted higher oscillatory gating ratios, indicative of age-related impairments in inhibitory function. Specifically, elevations in life stress significantly modulated the neural response to the first stimulation in the pair, while elevations in biological stress significantly modulated the neural response to the second stimulation in the pair. In contrast, neither elevations in life nor biological stress significantly predicted the gating of time-domain neural activity in the somatosensory cortex. Finally, our study is the first to link stress-induced decline in sensory gating to cognitive dysfunction, suggesting that gating paradigms may hold promise for detecting discrepant functional trajectories in age-related pathologies in the future.

Purpose Dysphagia is thought to be prevalent and a leading cause of morbidity and mortality in people with Parkinson disease (PwPD). The aim of this study was to compare the frequencies of atypical and extreme values for measures of swallowing physiology in PwPD and in an age- and sex-matched cohort of healthy adults. Atypical and extreme values were defined, respectively, as values falling in the 25% and 5% tails of the reference distribution for healthy adults under age 60 years. Method A standard videofluoroscopy (VF) protocol was performed in 17 adults with mild PD and 17 age- and sex-matched healthy adults using 20% w/v liquid barium ranging from thin to extremely thick consistency. Blinded VF analysis was performed according to the Analysis of Swallowing Physiology: Events, Kinematics and Timing Method. Frequencies for atypical and extreme values were tabulated by cohort and compared using odds ratios. Results Increased frequencies of atypical values (> 25%) were seen in the PwPD for prolonged swallow reaction time, prolonged time-to-laryngeal-vestibule-closure (LVC), and poor pharyngeal constriction. However, these findings were also observed in the healthy controls. The PwPD showed significantly higher odds of atypical values for narrow upper esophageal sphincter (UES) diameter on thin liquids, a short hyoid-burst-to-UES-opening interval on extremely thick liquids, and prolonged time-to-LVC, LVC duration, and UES opening duration on multiple consistencies. The frequencies of extreme values failed to show any significant cohort differences for any parameter. Conclusions In this study, a group of people with mild PD did not show clear evidence of swallowing impairments distinct from the changes seen in a healthy age-matched control group when odds ratios were used to compare the frequencies of atypical values between PwPD and the control group; only a few parameters showed significant differences. These were findings of significantly higher frequencies in PwPD of prolonged LVC and UES opening duration. Supplemental Material https://doi.org/10.23641/asha.15032241

The gut microbiota is increasingly recognized as an important regulator of host immunity and brain health. The aging process yields dramatic alterations in the microbiota, which is linked to poorer health and frailty in elderly populations. However, there is limited evidence for a mechanistic role of the gut microbiota in brain health and neuroimmunity during aging processes. Therefore, we conducted fecal microbiota transplantation from either young (3–4 months) or old (19–20 months) donor mice into aged recipient mice (19–20 months). Transplant of a microbiota from young donors reversed aging-associated differences in peripheral and brain immunity, as well as the hippocampal metabolome and transcriptome of aging recipient mice. Finally, the young donor-derived microbiota attenuated selective age-associated impairments in cognitive behavior when transplanted into an aged host. Our results reveal that the microbiome may be a suitable therapeutic target to promote healthy aging. The gut microbiome can change with age and influence aging-related diseases systemically, including in the brain. The authors show that rejuvenation of the gut microbiome by fecal microbiota transplantation from young mice reverses aging-induced deficits in the hippocampal immune system, metabolome and transcriptome, and rescues selective cognitive deficits.

Background: Cataract is an age-related eye disease. Visual impairment from cataract can be restored by cataract surgery. In 2004 the Canadian federal government invested in a multibillion dollar wait time strategy to shorten the wait time for cataract surgery, a government-insured health service in all Canadian jurisdictions. We assessed if this nationwide policy reduced the number of Canadians waiting for cataract surgery as more individuals with cataract were free of cataract following the rapidly conducted surgery. Methods: In this cross-sectional study we analyzed data from randomly selected individuals aged greater than or equal to 45 years responding to the Canadian Community Health Survey (CCHS) in 2000/2001, 2003, 2005, and the CCHS Healthy Aging in 2008/2009. Information on cataract was obtained from self-reported questionnaire. The age- and sex-standardized prevalence of cataract was calculated for comparisons. Results: Cataract was reported by 0.93 million Canadians in 2000/2001, 0.99 million in 2003, 1.10 million in 2005, and 1.34 million in 2008/2009. This corresponds to an age- and sex-standardized prevalence of 8.9% in 2000/2001, 9.0% in 2003, 9.5% in 2005, and 10.2% (P

Background The World Health Organization has proposed a model of healthy aging built around the concept of functional ability, comprising an individual’s intrinsic capacity, the physical and social environment they occupy, and interactions between the two. However, these constructs have been poorly defined. We examined the structure of intrinsic capacity in a representative sample of the Chinese population aged 60 years and older and assessed its value in predicting declining performance in instrumental activities of daily living (IADLs) and activities of daily living (ADLs) using similar methods to a construct validation previously undertaken in an English cohort. Methods Deidentified data were accessed on 7 643 participants of the China Health and Retirement Longitudinal Study 2011 and 2013 waves. Incrementally related structural equation modeling was applied, including exploratory and confirmatory factor analysis, and path analysis. Multiple linear regression tested construct validity, and simple and serial mediation models assessed predictive validity. Results Factor loadings for the models showed a clear structure for intrinsic capacity: 1 general factor with 5 subfactors—locomotor, cognitive, psychological and sensory capacities, and vitality (reflecting underlying physiologic changes). Intrinsic capacity predicted declining performance in both IADLs (standardized coefficient (SE) −0.324 (0.02), p < .001) and ADLs (−0.227 (0.03), p < .001), after accounting for age, sex, education, wealth, and number of chronic diseases. Each characteristic was associated with intrinsic capacity, providing strong construct validity. Conclusions Assessment of intrinsic capacity provides valuable information on an individual’s subsequent functioning beyond that afforded by age, other personal factors, and multimorbidity.

Made available in DSpace on 2022-04-28T19:42:29Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01 The practice of physical activity (PA) is an alternative to promote healthy aging. However, the index of physical inactivity of this population is high, being important to investigate factors that can influence this behavior. Thus, this study aimed to analyze associations between PA and sociodemographic, antropometric, functional and psychosocial factors, and to identify the most significant psychosocial predictors for the practice of PA in older adults. A quantitative cross-sectional study was performed with a random sample of 208 older adults (69.9 years ± 6.48 years and 55.3% men). Validated instruments were used to assess PA, functional capacity, self-efficacy, social support and perceived benefits and barriers for PA. There were significant associations between PA and education (r = 0.33), self-efficacy (r = 0.56), social support from friends (r = 0.58) and family (r = 0.25), perceived benefits (r = 0.52) and barriers (r = -0.45). Self-efficacy was the most significant psychosocial predictor for PA in older adults (β = 0.346), followed by perceived barriers (β = 0.152), social support from friends (β = 0.019), perceived benefits (β = 0.118) and social support from family (p = 0.019). This study suggests the importance of psychosocial aspects for the promotion of active aging. Santa Catarina State University São Paulo State University São Paulo State University

A reliable model of biological age is instrumental in the field of geriatrics and gerontology. This model should account for the heterogeneity and plasticity of aging and also accurately predict aging-related adverse outcomes. Epigenetic age models are based on DNA methylation levels at selected genomic sites and can be significant predictors of mortality and healthy/unhealthy aging. However, the biological function of DNA methylation at selected sites is yet to be determined. Frailty is a syndrome resulting from decreased physiological reserves and resilience. The frailty index is a probability-based extension of the concept of frailty. Defined as the proportion of health deficits, the frailty index quantifies the progression of unhealthy aging. The frailty index is currently the best predictor of mortality. It is associated with various biological factors and provides insight into the biological processes of aging. Investigation of the multi-omics factors associated with the frailty index will provide further insight.

Objectives To describe the characteristics and relationships of social isolation and health promoting behaviors of Chinese older adults with different health statuses. Methods Totally 485 older adults were recruited. They were divided into three groups based on their health status: healthy group (n = 72), group with one disease (n = 183) and group with multimorbidity (n = 230). Lubben Social Network Scale-6 and Health-Promoting Lifestyle Profile II were used to measure their social isolation and health-promoting behaviors, respectively. Results Among the aged with one disease or multimorbidity, 30.6% (56/183) and 31.7% (73/230) were socially isolated, respectively, based on the score of the Lubben Social Network Scale-6. The three groups differed significantly in health-promoting behaviors and scores on several subscales. The group with multimorbidity exhibited more social isolation and fewer health-promoting behaviors than other groups. Social isolation was among the factors adversely affecting health-promoting behaviors in older adults. Conclusions Health care providers should help older adults with multimorbidity preserve the remaining abilities to improve health-promoting behaviors. Meanwhile, it is important to support healthy older adults to increase self-responsibility to achieve healthy aging.

Astrocytes play a formative role in memory consolidation during physiological conditions; when dysregulated, astrocytes release glial fibrillary acidic protein (GFAP), which has been linked with negative memory outcomes in animal studies. We examined the association between blood GFAP, memory, and white matter (WM) integrity, accounting for blood markers of AD pathology (i.e., Aβ42) and neurodegeneration (i.e., total tau; neurofilament light chain) in 114 older adults (asymptomatic, n = 69; MCI/AD dementia, n = 45). Higher levels of GFAP were associated with lower memory scores (p0.0001), such that for 1 SD increase in mean GFAP values, the memory composite score decreased on average by 0.49 (Standard error = 0.071). These results remained significant after controlling for diagnostic status and AD-related blood biomarkers. Higher GFAP was also related to lower WM integrity in regions vulnerable to AD pathology; however, WM integrity did not account for the association between GFAP and memory. Study findings suggest that higher blood levels of a marker of astrogliosis may reflect impoverished memory functions and white matter health, independent of markers of amyloid or neurodegeneration.

Neurodegenerative diseases and their associated cognitive decline are known to be more prevalent during aging. Recent evidence has uncovered the role of microglia, the immunocompetent cells of the brain, in dysfunctions linked to neurodegenerative diseases such as is Alzheimer's disease (AD). Similar to other pathologies, AD is shown to be sex-biased, with females being more at risk compared to males. While the mechanisms driving this prevalence are still unclear, emerging data suggest the sex differences present in microglia throughout life might lead to different responses of these cells in both health and disease. Furthermore, microglial cells have recently been recognized as a deeply heterogeneous population, with multiple subsets and/or phenotypes stemming from diverse parameters such as age, sex or state of health. Therefore, this review discusses microglial heterogeneity during aging in both basal conditions and AD with a focus on existing sex differences in this process.

Healthy aging hemodynamics is known to exhibit a time-dependent loss of function. We aimed at verifying whether older men would have a slowed cardiac output and stroke volume dynamics in response to the onset (“on”) and on recovery (“off”) of exercise in comparison to young men. Twenty healthy active men (10 young and 10 older) were recruited. Participants performed an incremental cardiopulmonary exercise testing on a cycle ergometer, and on another day, 3 constant workload tests in different intensities. Compared to younger, older men exhibited a slower cardiac output and stroke volume dynamics in both on and off transients for all exercise intensities (all P < 0.05). During higher intensities, both younger and older men had slower hemodynamic kinetics compared to lower intensities (all P < 0.05). There was strong negative relationship between the time constant of cardiac output on-kinetics during high-intensity with maximal exercise performance in both groups (r = –0.88, P < 0.01). We interpret these findings to mean that healthy older men have slowed hemodynamic kinetics compared to younger, but this difference becomes less evident in higher intensities of exercise.

Sarcopenia is a progressive and widespread skeletal muscle disease that is related to an increased possibility of adverse consequences such as falls, fractures, physical disabilities and death, and its risk increases with age. With the deepening of the understanding of sarcopenia, the disease has become a major clinical disease of the elderly and a key challenge of healthy ageing. However, the exact molecular mechanism of this disease is still unclear, and the selection of treatment strategies and the evaluation of its effect are not the same. Most importantly, the early symptoms of this disease are not obvious and are easy to ignore. In addition, the clinical manifestations of each patient are not exactly the same, which makes it difficult to effectively study the progression of sarcopenia. Therefore, it is necessary to develop and use animal models to understand the pathophysiology of sarcopenia and develop therapeutic strategies. This paper reviews the mouse models that can be used in the study of sarcopenia, including ageing models, genetically engineered models, hindlimb suspension models, chemical induction models, denervation models, and immobilization models; analyses their advantages and disadvantages and application scope; and finally summarizes the evaluation of sarcopenia in mouse models.

Strategies to reduce dementia risk are needed to minimize the burden of this growing public health concern. Most individuals are not aware that dementia risk reduction is possible, let alone how this could be achieved. Health education, such as public awareness campaigns on the topic of dementia risk reduction, can meet this need. A public health campaign (including social media and offering an online individual risk assessment tool) was carried out over a 7-month period in Flanders, Belgium. Impact was assessed in two independent online surveys, before (n = 1003) and after the campaign (n = 1008), in representative samples of adults aged 40–75 years. Questions regarding personal needs, wishes and barriers were also included. After the campaign, more individuals (10.3%) were aware that dementia risk reduction is possible than before the campaign, and more individuals correctly identified 10 out of 12 surveyed modifiable dementia risk and protective factors. However, no differences were observed in low-educated individuals. Further, specific differences in potential needs, wishes and barriers for future campaigns or interventions were observed between demographic strata. The majority of the respondents (89%) indicated that they would welcome more information on improving their brain-health. More than half (54%) also believed that they lacked the necessary knowledge to make brain-healthy behavior changes. In conclusion, effective public awareness campaigns on the topic of dementia risk reduction are feasible and timely, given the state of the evidence. Special efforts need to be made to develop effective campaigns, tailored towards low-educated individuals.

Objectives The Gateway to Global Aging Data (Gateway; g2aging.org) is a data and information platform developed to facilitate cross-country analyses on aging, especially those using the international family of Health and Retirement studies. We provide a brief introduction to the Gateway to Global Aging Data, discussing its potential for cross-national comparisons of family, social environment, and healthy aging. Methods We summarize the survey metadata, study characteristics, and harmonized data available from the Gateway, describing the population represented in each study. We portray cohort characteristics and key measures of health and social environment from 37 countries in North America, Europe, and Asia using harmonized data. Results Significant cross-country heterogeneity was observed in many measures of family, social environment, and healthy aging indicators. For example, there was a threefold difference in coresidence with children, ranging from 14% in Sweden to over 46% in Spain and Korea in 2014. From 2002 to 2014, the difference between informal care receipt in individuals of low and high wealth decreased by 6% in the United States and remained unchanged in England. The percentage of individuals aged 50–59 living alone in 2012 varied 15-fold, from a low of 2% in China to a high of 30% in Mexico. Discussion By partnering with nationally representative studies around the globe, the Gateway to Global Aging Data facilitates comparative research on aging through the provision of easy-to-use harmonized data files and other valuable tools.

Over the last 50 years, the Indian population aged 50 years and above (older adults) has quadrupled and is expected to comprise 404 million people in 2036, representing 27% of the country's projected population. Consequently, the contribution of chronic disease to older adults' total burden of diseases in India is likely to escalate. Disease burden is notably amplified by immunosenescence, a deterioration of the immune system that develops with age, leading to increasing susceptibility to infectious diseases and other comorbidities. Older adults with infectious diseases have a higher incidence and likelihood of life-threatening comorbidities such as coronary artery disease, arrhythmia, stroke, myocardial infarction, hypertension, dyslipidemia, and diabetes mellitus. Therefore, immunization of older adults through vaccination might greatly reduce the burden imposed by vaccine preventable infectious diseases in this population. Here, we review evidence relevant to the disease burden among adults aged ≥ 50 years in India, and existing vaccination recommendations. Furthermore, we suggest a set of routine vaccinations for healthy older adults in India. There is a clear mandate to recognize the contributions of older adults to society and embrace strategies promoting healthy aging, which is described by the World Health Organization as the process of developing and maintaining functional ability and well-being in older age. Increasing vaccination awareness and coverage among older adults is an important step in that direction for India.

Background Musculoskeletal conditions are the leading cause of years lived with disability for older adults. Limitations in functional ability affect healthy aging for aging populations worldwide. Thus, it is important to assess effects of interventions on the multiple dimensions of function for older adults. Objectives To assess: (1) which domains of function are assessed in reviews published by the Cochrane Musculoskeletal Group inclusive of older adults, and (2) the extent to which these reviews evaluate effects and/or applicability of findings for older adults. Methods We included all reviews published by the Cochrane Musculoskeletal Review Group after 2015 including participants over the age of 50 (n = 52). We extracted data on how the activities and participation domains of the International Classification of Functioning (ICF) were measured. We assessed the extent to which reviews included methods to evaluate effects across age, according to the framework in the Cochrane Handbook chapter on equity and specific populations. Results The median age of participants across reviews was 54 years (range 16–94). ICF domains assessed in reviews, in descending order of frequency, were: domestic life (90%), mobility (89%), self-care (87%), interpersonal interactions and relationships (65%), community, social, and civic life (64%), major life areas (31%), communication (2%), general tasks and demands (0%) and learning and applying knowledge (0%). In evaluating effects across age, the age of participants was described by 73% of reviews and 54% mentioned age in the description of the condition, 21% planned subgroup analysis by age and none were able to conduct this analysis. Only 17% described applicability of results to older people. Conclusions Reviews published by the Cochrane Musculoskeletal Group inclusive of older adults assess most domains of functional ability with the exception of communication, general tasks and knowledge domains. None of these reviews were able to conduct a subgroup analysis across age, indicating a need to improve the consideration of age in both Cochrane reviews as well as in primary studies.

Insulin signalling declines with increasing age and impacts skeletal muscle function and longevity in animal models. Our aim was to assess the relationships between insulin resistance (IR) and frailty and mortality in a unique community-dwelling cohort of older people. 991 non-diabetic subjects from the Toledo Study of Healthy Ageing (TSHA) cohort were included. IR was estimated by the homeostasis model assessment index (HOMA-IR) at baseline while frailty was determined by frailty phenotype (FP) and Frailty Trait Scale (FTS) at baseline and after 5-year follow-up. Deaths were also determined. Multivariate regression models were used to analyze the effects of HOMA-IR on outcomes. Age, gender, BMI, education level, cardio- and cerebro-vascular disease, glomerular filtration rate, and disability were included as potential confounding variables in progressive adjustment models. IR determined as increasing log HOMA-IR was inversely associated with risk of mortality. The association remained significant for all adjustment models (HR: 0.64–0.69). When we analyzed survival curves, the higher the HOMA-IR tertile, the lower the mortality rate (highest vs lowest tertile, p = 0.0082). In contrast, IR increased the risk of incident frailty determined by FP (OR 1.81 [1.14–2.87]) as well as deterioration of frailty status determined by worsening in FTS score (OR 1.28 [1.01–1.63]) at 5-year follow-up. In non-diabetic older subjects, IR significantly increases the risk for frailty and functional decline but decreased the risk of death at 5-year follow-up. This finding raises the need of assessing the effect of biomarkers on different outcomes before establishing their role as biomarkers of aging.

Menopause is one of the most important events in the female reproductive life cycle, being a transition from the reproductive to the nonreproductive stage. It is a milestone that may have a negative influence on quality of life and one that brings in several physiological changes that affect the life of a woman permanently. According to a Polish epidemiological forecast, in 2050 the average female life expectancy will be 87.5, which is 6.4 years longer than today. Thus, the life expectancy of women who will be 60 or older in 2050 will also extend. Therefore, strategies need to be optimized to maintain postreproductive health, in part because of increased longevity. The general gynecologist can expect to see more elderly female patients as the population continues to age. Office management of the gynecologic problems of geriatric women requires sensitivity to the special needs of this group. Nowadays, most women spend more than one-third of their lives after menopause; therefore there is plenty of opportunity for gynecologists to cater to the needs of postmenopausal women. It is in their scope of practice to help postmenopausal women through “healthy aging”. In this review we look into screenings, early identification, lifestyle modifications and appropriate intervention that may prevent many chronic conditions that cause morbidity and mortality during the postmenopausal years.

Introduction: The aim of this study is to clarify the association between repeated falls and the dominant/nondominant side in the open-eyed one-leg standing (OLS) test among people who are healthy or have mild cognitive impairment (MCI) or dementia in a community setting. We recruited 180 participants from 39 areas in the town of Wakuya. Methods: This is a cross-sectional study. Participants were classified into 3 Clinical Dementia Rating (CDR) groups, i.e., CDR 0 (healthy, n = 71), CDR 0.5 (MCI, n = 85), and CDR 1+ ( n = 23), and they were investigated for motor function (grip strength, 6-m normal gait speed, timed up and go test, and OLS test) and falls during the past year. Results: Subjects with a CDR of 0.5 had higher rates of single and repeated falls (13.0 and 23.4%, respectively) than the CDR 0 group (12.1 and 4.5%, respectively), as did those in CDR 1+ group (15.0 and 30.0%). For the CDR 0.5 group, the frequency of falls was negatively (biologically meaningful direction) correlated with the left OLS time. No significant correlations with falls were found for other motor function tests. Another analysis separating the CDR 0.5 group into 2 subgroups (repeated falls vs. no or a single fall) also showed that the left OLS time was lower in subjects with repeated falls. Conclusion: People with MCI who had fallen repeatedly in the year before the assessment had a significantly lower left OLS time compared to those who had not fallen or had had 1 fall with MCI. None of the other physical measures were associated with past repeat falls including OLS on the dominant right side. No such findings were noted in the CDR 0 and CDR 0+ groups.

Purpose of Review To identify important home care (HC) aide occupational safety and health (OSH) hazards and examine how addressing these can improve aide health and the delivery of HC services overall. Specifically, this review seeks to answer: Why is HC aide OSH important? What are the most significant OSH challenges? How can improving HC aide OSH also improve the safety and health of their clients? What implications do the findings have for future research? Recent Findings HC is one of the fastest growing US industries. Aides comprise its largest workforce and are increasingly needed to care for the rapidly aging population. There is an aide shortage due in part to instabilities in HC work organization and to serious job-specific hazards, resulting in aides losing work time. Recent social, economic, and technological factors are rapidly changing the nature of HC work, creating OSH hazards similar to those found in nursing homes. At the same time, aides are experiencing social and economic inequities that increase their vulnerability to OSH hazards. These hazards are also a burden on employers who are challenged to recruit, retain, and train aides. OSH injuries and illness interrupt the continuity of care delivery to clients. Many OSH hazards also put HC clients and families at risk. Summary A new framework and methodologies are needed to assess aide and client safety together in order to guide future HC research, policies, and practices. Government, industry, and labor commitment is needed to fund and coordinate a comprehensive, multidisciplinary research program.

To evaluate the effect of aging, intra- and intersession repeatability and regional scotopic sensitivities in healthy and age-related macular degeneration (AMD) eyes. Intra- and intersession agreement and effect of age was measured in healthy individuals. The mean sensitivity (MS) and pointwise retinal sensitivities (PWS) within the central 24° with 505 nm (cyan) and 625 nm (red) stimuli were evaluated in 50 individuals (11 healthy and 39 AMD eyes). The overall intra- and intersession had excellent reliability (intraclass correlation coefficient, ICC > 0.90) and tests were highly correlated (Spearman rs = 0.75–0.86). Eyes with subretinal drusenoid deposit (SDD) had reduced PWS centrally, particularly at inferior and nasal retinal locations compared with controls and intermediate AMD (iAMD) without SDD. There was no difference in MS or PWS at any retinal location between iAMD without SDD and healthy individuals nor between iAMD with SDD and non-foveal atrophic AMD groups. Eyes with SDD have reduced rod function compared to iAMD without SDD and healthy eyes, but similar to eyes with non-foveal atrophy. Our results highlight rod dysfunction is not directly correlated with drusen load and SDD location.

Background Our study examined the association between social participation and healthy aging using a community-based cohort study among Japanese older adults. Methods This prospective study was conducted in Ohsaki City, Japan, and included 7226 participants aged ≥65 years at the baseline survey in 2006. We obtained information on frequency of participation in 3 types of community activities (ie, neighborhood activities, hobbies, and volunteer activities) at baseline. Exposure was measured by the number of types of community activities participated in and participants were categorized into 4 groups (ie, none, 1 type, 2 types, and 3 types). The primary outcome was healthy aging as assessed by a questionnaire survey conducted in 2017, and was defined as meeting the following 4 criteria: free of disability, free of depression, high health-related quality of life, and high life satisfaction. We used multiple logistic regression models to calculate the corresponding odds ratios and 95% confidence intervals. Results During 11 years of follow-up, 574 (7.9%) participants attained healthy aging. Compared with participants not participating in any activity, the multivariable-adjusted odds ratios (95% confidence intervals) were 1.90 (1.40, 2.59) for those participating in 1 type, 2.49 (1.84, 3.38) for 2 types, and 3.06 (2.30, 4.07) for 3 types (p for trend < .0001). Furthermore, for each type of community activity, a higher frequency of participation was related to higher probability of healthy aging. Conclusions Our study suggests that social participation is associated with the promotion of healthy aging, and that the benefits were observed across different types of community activities.

The traditional disease-oriented model of healthcare is inadequate to address the needs of the older population. Greater attention should be given to strategies that promote healthy aging. Recently proposed constructs of intrinsic capacity (IC) and physical resilience (PR) hold great potential to reshape geriatric medicine and aging research. These constructs accentuate the positive health attributes of older people in contrast to the popular frailty construct that is centered on functional deficits. IC was introduced by the World Health Organization (WHO) as a composite of all the physical and mental capacities. WHO has emphasized enhancement of IC throughout the life course so as to maintain functional ability in old age. PR, recently highlighted by the National Institute on Aging, is the ability to successfully cope with stressors. High levels of resilience can result in desirable clinical and functional outcomes after stressors. Therefore, it is important to understand the underlying physiology of PR and the risk factors contributing to diminished PR. The main goal of this article is to explore the potential relationship between IC and PR. Based on a classical theory of aging, we postulate that IC is a determinant of PR and is also a high-level integrative measure of physiologic reserve which is the fundamental factor underlying one's ability to withstand stressors. A major implication of our postulates is that even though IC is only one of the many determinants of PR, it could serve as an important intervenable target for enhancing resilience in older adults.

ZusammenfassungDie Vitamine D und K2 interagieren auf vielen Stoffwechselwegen, v. a. im Kalzium- und Knochenstoffwechsel und haben günstige Effekte für die Knochendichte. Vitamin-K-abhängige Proteine sind an der Blutgerinnung beteiligt und schützen Arterien vor arteriosklerotischer Mikrokalzifizierung. Ein Mangel an Vitamin B12 und/oder Folsäure resultiert in Hyperhomocysteinämie. Diese ist im fortgeschrittenen Alter mit einer Abnahme von kognitiver Leistungsfähigkeit und Hirngröße assoziiert und gilt als Risikofaktor für eine Alzheimer-Demenz. Coenzym Q10 (Ubiquinon) spielt eine essenzielle Rolle bei der zellulären Energieproduktion. Das Vitaminoid ist Zellregulator, Antioxidanz und beeinflusst die Aktivität zahlreicher Gene. So beugt es Zellläsionen sowie Inflammaging vor. Das Verhältnis der reduzierten Form Ubiquinol zu Ubiquinon im Blut ist ein Marker für oxidativen Stress. Eine unzureichende Versorgung führt zu Störungen u. a. im Herz-Kreislauf- und Immunsystem.
