Geriatrics (Basel) 2024; 9:108. [PMID: 39311233 PMCID: PMC11417934 DOI: 10.3390/geriatrics9050108] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2024] [Revised: 08/06/2024] [Accepted: 08/22/2024] [Indexed: 09/26/2024] Open
Abstract
Age-related declines in the musculoskeletal system may place additional demands on the lumbar spine during everyday activities such as walking. This study aimed to investigate age-related differences in the functional demand (FD) of walking on the lumbar spine in older and younger adults. A motion analysis system with integrated force plates was used to acquire kinematic and kinetic data on 12 older (67.3 ± 6.0 years) and 12 younger (24.7 ± 3.1 years) healthy men during walking at a self-selected speed along a 10 m walkway. Isokinetic dynamometry was used to acquire the maximal joint moment capacity of the lumbar spine. The FD of the lumbar spine was calculated as the muscle moment during key phases of the gait cycle (GC) relative to the maximum moment capacity of the lumbar spine. The difference in FD between age groups was not significant (p = 0.07) and there were no significant differences between the young group (YG) and older group (OG) for any individual phase in the GC. Despite the lack of statistical significance, the results indicate that a practical difference may exist, as walking was approximately 20% more functionally demanding on the lumbar spine in the OG compared to the YG. Therefore, older adults may employ modified gait strategies to reduce mechanical load whilst walking to fall within the limits of their maximal force-producing capacity in the lumbar spine, which may have implications for injury risk.

MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1231. [PMID: 39202512 PMCID: PMC11356010 DOI: 10.3390/medicina60081231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/27/2024] [Revised: 07/25/2024] [Accepted: 07/27/2024] [Indexed: 09/03/2024]
Abstract
Background and Objectives: Frailty in older adults is associated with adverse health outcomes. This study aimed to analyze the frailty status of community-dwelling older adults in Taiwan using the Kihon Checklist (KCL) and explore associations with demographic, physiological, and functional factors. Materials and Methods: In this cross-sectional study, 278 community-dwelling older adults were classified as robust, prefrail, or frail based on their KCL scores. Participants underwent physical fitness assessments including muscle strength and endurance tests, walking speed tests, and flexibility tests. One-way ANOVA and logistic regression analyses were used to examine differences and associations between frailty status and physical fitness indicators. Results: 36% of participants were robust, 47.1% prefrail, and 16.9% frail. The robust group significantly outperformed the prefrail and frail groups in the 30 s sit-to-stand test, 2.44 m sit-to-walk test, and walking speed (p < 0.001). The 2.44 m sit-to-walk test was a significant predictor of prefrailty (OR = 1.18, 95% CI = 1.02-1.36) after adjusting for other physical fitness indicators. Conclusions: Lower limb functional capacity, particularly in the 2.44 m sit-to-walk test, was significantly associated with pre-frailty among community-dwelling older adults in Taiwan. Early screening, the classification of frailty by the Kihon Checklist, and targeted interventions focusing on lower limb strength, endurance, and mobility are crucial for preventing and delaying frailty progression in older populations.

Abstract
The present research examines the association between purpose in life - a component of well-being defined as the feeling that one's life is goal-oriented and has direction - and slow walking speed and the risk of developing slow walking speed over time. Participants (N = 18,825) were from three established longitudinal studies of older adults. At baseline, participants reported on their purpose in life, and interviewers measured their usual walking speed. Walking speed was measured at annual or biannual follow-up waves up to 16 years later. Random-effects meta-analysis was used to summarize the estimates from the individual studies. Every standard deviation higher in purpose in life (as a continuous measure) was associated with a lower likelihood of cross-sectional slow walking speed at baseline (meta-analytic OR = .80, 95% CI = .77-.83). Among participants who did not have slow walking speed at baseline (n = 8,448), every standard deviation higher purpose in life was associated with a lower likelihood of developing slow walking speed over the up to 16 years of follow-up (meta-analytic HR = .93, 95% CI = .89-.96). Physical activity and disease burden accounted for 25% and 14% of the cross-sectional and longitudinal associations, respectively. The associations were independent of age, sex, race, ethnicity, and education and not moderated by these factors. Higher purpose in life is associated with a lower risk of slow walking speed and a lower risk of developing slow walking speed over time. Purpose in life is a psychological resource that may help to support aspects of physical function, such as walking speed, and may help support better function with age.

Abstract
This article updates and extends an earlier meta-analysis (Westerhof et al., 2014) on the longitudinal effects of subjective aging (SA) on health outcomes. A systematic search in different databases (APA PsycInfo, PubMed, Web of Science, and Scopus) resulted in 99 articles, reporting on 107 studies. Participants: Studies had a median sample size of 1,863 adults with a median age of 66 years. A randomized effect meta-analysis showed a significant, small effect (likelihood ratio = 1.347; 95% confidence interval [1.300, 1.396]; p < .001), similar in magnitude to the previous meta-analysis of 19 studies. Although the results showed high heterogeneity in the longitudinal link between SA and health outcomes, there were no differences in effects according to chronological age of participants, welfare state status (more or less developed social security system), length of follow-up, type of health-related outcome, or quality of the study. Effects were stronger for multiitem measures of self-perceptions of aging than for the frequently used single-item measures assessing subjective age, especially for indicators of physical health. Based on this meta-analysis, building on five times more studies than the 2014 review, we consider the associations of measures of SA with health and longevity across time as robust, albeit small in size. Future research should concentrate on the clarification of pathways mediating the relation between SA and health outcomes, as well as potential bidirectional effects.

Abstract
BACKGROUND Self-perceptions of aging (SPA) are important psychosocial factors that lead to a wide range of outcomes including dementia. However, the relationships between positive SPA and motoric cognitive risk syndrome (MCR) which is a predementia syndrome are still unknown. This study aimed to reveal the associations of positive control and aging awareness of SPA with the risk of MCR and its components. METHODS A cross-sectional design was conducted among 1137 Chinese community-dwelling older adults. Positive control and aging awareness were defined by two dimensions of SPA (Positive control and Timeline chronic). MCR was determined according to definition. Multivariable logistic regression was used to examine the associations. RESULTS The overall prevalence of MCR was 11.5% (mean age = 71.62 ± 5.22). After adjusting for depression, anxiety, and cognitive function, positive control was associated with reduced risk of MCR (OR = 0.624, 95% CI 0.402-0.969, P = 0.036), subjective cognitive complaints (SCC) (OR = 0.687, 95% CI 0.492-0.959, P = 0.027), and gait speed (GS) (OR = 0.377, 95% CI 0.197-0.720, P = 0.003), respectively. Aging awareness was merely related to increased risk of MCR (OR = 1.386, 95% CI 1.062-1.810, P = 0.016). CONCLUSIONS This study highlights the crucial associations of positive control and aging awareness with MCR and its components. Our results emphasize that positive belief in control and adaptive aging awareness might be promising targets for preventing MCR.

Abstract
The walking speed of pedestrians is not only a reflection of one's physiological condition and health status but also a key parameter in the evaluation of the service level of urban facilities and traffic engineering applications, which is important for urban design and planning. Currently, the three main ways to obtain walking speed are based on trails, wearable devices, and images. The first two cannot be popularized in larger open areas, while the image-based approach requires multiple cameras to cooperate in order to extract the walking speed of an entire street, which is costly. In this study, a method for extracting the pedestrian walking speed at a street scale from in-flight drone video is proposed. Pedestrians are detected and tracked by You Only Look Once version 5 (YOLOv5) and Simple Online and Realtime Tracking with a Deep Association Metric (DeepSORT) algorithms in the video taken from a flying unmanned aerial vehicle (UAV). The distance that pedestrians traveled related to the ground per fixed time interval is calculated using a combined algorithm of Scale-Invariant Feature Transform (SIFT) and random sample consensus (RANSAC) followed by a geometric correction algorithm. Compared to ground truth values, it shows that 90.5% of the corrected walking speed predictions have an absolute error of less than 0.1 m/s. Overall, the method we have proposed is accurate and feasible. A particular advantage of this method is the ability to accurately predict the walking speed of pedestrians without keeping the flight speed of the UAV constant, facilitating accurate measurements by non-specialist technicians. In addition, because of the unrestricted flight range of the UAV, the method can be applied to the entire scale of the street, which assists in a better understanding of how the settings and layouts of urban affect people's behavior.

Abstract
AIM To determine the relationship between the subjective age, higher-life function, and new certification for the need for long-term care among older adults in the community. METHODS A mail survey was conducted in 2016 among community-dwelling older adults, and the 2,323 participants who were available for follow-up in 2019 were included in the analysis. Subjective age was evaluated using the following three items in response to the question "Please answer how old you feel you are": "Same as actual age," "Feel younger," and "Feel older." Other assessments included an evaluation of the higher-life function, Geriatric Depression Scale scores, general self-efficacy, and exercise adherence. In addition, at follow-up, we investigated whether or not participants required new certification for the need for long-term care. RESULTS At baseline, participants who felt "older than their actual age" had a significantly lower life function and general self-efficacy and were less likely to exercise at least once a week than the other groups. Furthermore, those who felt "older than their actual age" was more likely than the other groups to be newly certified as needing long-term care, while those who felt "younger than their actual age" were less likely to receive new certification. A logistic regression analysis revealed that "feeling older" was a risk factor for being certified as needing long-term care, even after adjusting for other factors (odds ratio= 3.33, 95% confidence interval: 1.02-10.94, p=0.047). CONCLUSIONS Among community-dwelling older adults, those with a subjective age exceeding their chronological age were expected to show a decreased life function in the future and an increased risk of needing long-term care.

Abstract
OBJECTIVES Falls are a common and serious health problem. The present study examined the association between subjective age (i.e., feeling younger or older than one's chronological age) and falls in two large national samples. METHOD Participants, aged 65 to 105 years old, were drawn from the National Health and Aging Trends Study (NHATS) and the Health and Retirement Study (HRS). Data on falls, subjective age, demographic factors, was available from 2,382 participants in HRS and 3,449 in NHATS. Falls were tracked for up to 8 (HRS) and 7 (NHATS) years. RESULTS Cox regression analyses that included demographic covariates indicated that older subjective age increased the risk of falling in HRS (hazard ratio [HR]=1.17, 95% confidence interval [CI]=1.08-1.27), and in NHATS (HR=1.06, 95%CI=1.00-1.13). When compared to people who felt younger, people who reported an older subjective age had a higher risk of fall (HRS: HR=1.65, 95% CI=1.33-2.04; NHATS: HR=1.44, 95% CI=1.15-1.79). The associations remained significant after accounting for depressive symptoms, handgrip strength, chronic diseases, and cognitive impairment in HRS only. DISCUSSION These results confirm the role of subjective age as an important health marker in the aging population. Subjective age assessment can help identify individuals at greater risk of falls.

Abstract
Background There is increasing evidence that subjective age is an important predictor of beneficial health outcomes besides chronological age. However, little is known about the factors associated with younger subjective age. This study aimed to identify which factors are predictive of feeling younger in old age. In this context, feeling younger was defined as an individual's perception of being younger than their current chronological age. Methods Data from 4,665 community-dwelling older people were drawn from wave 7 (2020) of the German Aging Survey (DEAS), a nationally representative study in Germany. Network, mediation, and binomial logistic regression analyses were performed to reveal the associations between feeling younger and biopsychosocial factors. Results A total of 4,039 participants reported feeling younger, while 626 did not. Older chronological age, engaging in sports more frequently, a better standard of living, a better state of health, higher satisfaction with life, more positive attitudes toward one's aging, and fewer depressive symptoms are associated with feeling younger in older people. Conclusion The present study provides novel and consistent evidence regarding the association between feeling younger and biopsychosocial factors. Further research is needed to confirm these factors and identify how they can be adapted in potential intervention studies to generate the life and health circumstances that allow older people the benefit of feeling younger.

Abstract
Although subjective age has been associated with a range of health-related outcomes, there has been little systematic study on the relationship between the subjective age and physical fitness in a given population. The purpose of this study was to determine the prospective association between subjective age and physical fitness in community-dwelling older adults. A sample of 276 older people who lived in the community was studied. Subjective age was measured by a face-to-face interview. Grip strength, balancing on one leg with eyes open, the 30 s chair stand test, 4 m habitual walk, and 6 min walk test were measured to reflect physical fitness. Results indicated that the felt younger older adults had a higher level of physical fitness compared to their felt older and felt the same counterparts. Multiple linear regression analysis indicated that all the measured physical fitness items were significantly associated with subjective age in older men. All of the measured physical fitness items except for the 4 m habitual walk were remarkably related to subjective age in older women. The findings suggest that subjective age is closely associated with physical fitness in community-dwelling older adults. Much attention should be paid to the promotion of physical fitness to improve the subjective age of older adults.

Abstract
OBJECTIVE Subjective age has been implicated in a range of health outcomes but its associations with Fear of Falling (FoF) are unknown. The present study examined the relation between subjective age and FoF in large national sample. METHODS Participants were drawn from the National Health and Aging Trends Study (NHATS, 2011-2017). 1,679 participants provided data on FoF, subjective age, demographic factors, depressive symptoms, prior falls, self-rated health and measures of the Short Physical Performance Battery. FoF was assessed again 7 years later. RESULTS Regression analyses revealed that an older subjective age was related to a 24% higher likelihood to develop FoF 7 years later. This association was independent of age, sex, educational attainment, race and prior falls. In addition, depressive symptoms, self-rated health, and physical inactivity mediated the associations between subjective age and FoF. CONCLUSIONS The present study showed that an older subjective age is related to the development of FoF over time, and further identified psychological and functional pathways that may explain this association. These results confirm the role of subjective age on one of the markers of frailty in the aging population.

Abstract
BACKGROUND There is a paucity of data on mid to long-term gait outcomes after total knee arthroplasty. The aims of this longitudinal study were: to assess the evolution of both clinical and gait outcomes before and up to seven years after primary total knee arthroplasty (TKA) in a cohort of patients with knee osteoarthritis. METHODS This study included 28 patients evaluated before and up to seven years after primary TKA with both gait analysis and patient reported outcomes; of these, 20 patients were evaluated one year after surgery as well. Kinematic outcomes during gait (gait velocity, dimensionless gait veolicity, maximal knee flexion and knee range of motion), pain relief, Western Ontario and MacMaster Osteoarthritis Index (WOMAC), quality of life and patient satisfaction were assessed and compared at each visit with the paired Wilcoxon signed rank test (p < 0.05). RESULTS The significant improvement achieved at one year after TKA was stable up to seven years after surgery, with all clinical and kinematic outcomes unchanged, except for gait velocity, with a significant decrease over time (1.3 (1.1-1.4) m/s one year after TKA versus 1.0 (0.9-1.1) m/s, p < 0.05 up to seven years after). CONCLUSION Patients with knee osteoarthritis significantly improve their clinical and kinematic outcomes at one year postoperatively and maintain the gain up to seven years after primary TKA, except for gait velocity which decreases over time, most likely along with ageing.

Abstract
Objectives Previous research on subjective age (SA), that is, how young or old a person feels relative to their chronological age, has shown that older adults tend to feel younger than they are (by about 15%–20%), but the extent of this effect depends, in part, on their health. However, as most of the studies have been conducted in Western countries, it is unclear how well these results generalize to culturally different samples. Objectives, therefore, were to examine SA in middle-aged and older adults from a very low-income setting in rural Burkina Faso, to examine associations between SA and health/quality of life-related measures, and to compare findings with Western studies. Methods Representative, cross-sectional sample of N = 3,028 adults (≥40 years, recruited in 2018) from north-western Burkina Faso. Data included questionnaires on depression (Patient Health Questionnaire-9) and quality of life (World Health Organization Quality of Life scale, including subjective health) as well as performance-based and objective health-related measures (Community Screening Instrument for Dementia as cognitive screening, walking speed). Results Respondents felt on average 3% younger (SD = 0.13) than their chronological age, with 48% (95% confidence interval: 0.46–0.50) feeling younger—27 percentage points lower than seen in representative Western studies. Lower depression, better walking speed, cognition, and quality of life were all associated with younger SA. Discussion Middle-aged and older adults in Nouna felt less young than similar age groups in Western studies. One of the reasons may be that youthfulness is less of a value outside Western cultures. As in Western studies, parts of the variation in SA can be explained by health parameters.

Abstract
Background Subjective age refers to how young or old individuals experience themselves to be and is associated with health status, behavioral, cognitive, and biological processes that influence frailty. However, little research has examined the relationship between subjective age and frailty among older adults. This study examined the bidirectional association between subjective age and frailty among community-dwelling older adults. Methods We used data from the 2011 to 2015 waves of the National Health and Aging Trends Study. Our sample consists of 2,592 community-dwelling older adults with complete data on main outcome variables. Subjective age was measured by asking participants, “What age do you feel most of the time?” Based on the five phenotypic criteria: exhaustion, unintentional weight loss, low physical activity, slow gait, and weak grip strength, frailty was categorized into robust = 0, pre-frailty = 1 or 2; frailty = 3 or more criteria met. Generalized estimating equation models were used to examine the concurrent and lagged association between subjective age and frailty. Results Participants were, on average, 75.2 ± 6.8 years old, non-Hispanic whites (76 %), female (58 %). 77 % of the participants felt younger, 18 % felt the same, and 5 % felt older than their chronological age. About 45 %, 46 %, and 9 % of the participants were robust, pre-frailty and frailty in the first wave, respectively. Generalized estimating equations revealed that an “older” subjective age predicted a higher likelihood of pre-frailty and frailty (OR, 95 % CI = 1.93, 1.45–2.56). Conclusions These findings suggest that people with older subjective age are more likely to be pre-frail/frail. Subjective age could be used as a quick and economical screening for those who are potentially frailty or at risk for frailty.

Abstract
The age that a person feels is a strong predictor of their well-being and long-term health, beyond chronological age, showing that people have a self-awareness that provides insight into their aging process. It appears this insight has broad implications for a person's everyday life and functioning. One's subjective age is shaped by metacognitive beliefs about aging, including both expectations about typical changes but most notably the awareness and interpretation of personal experiences. Subjective age has been described as multidimensional, aligning with life domains such as cognitive, social, and physical functioning. This perspective, coupled with laboratory studies that manipulate subjective age, suggests that situational context has an important role in determining the age a person feels. Here we review literature on subjective age with a focus on how research and theoretical perspectives should be adapted to integrate momentary experiences. We propose a contextual model that will help discriminate the links between situational influences and subjective age, as well as resulting behaviors that impact health and well-being. While most research has considered subjective age to be a relatively stable variable, we provide a novel account of how daily life offers a variety of situational contexts and experiences that directly impact the age a person feels at a given moment. We propose that studying moment-to-moment context is a critical next step in understanding the associations between subjective age, lifestyle choices, and health outcomes.

Abstract
OBJECTIVES The motoric cognitive risk (MCR) syndrome, characterized by cognitive complaints and slower gait speed, is a pre-dementia syndrome associated with dementia and mortality risk. The present study examined whether subjective age, that is how old or young individuals feel relative to their chronological age, is related to concurrent and incident MCR syndrome. A relation between subjective age and MCR will inform knowledge on psychological factors related to dementia risk, identify who is at greater risk, and suggest a potential target of intervention. METHOD The study sample was composed of 6,341 individuals aged 65 to 107 years without dementia from the Health and Retirement Study (HRS), a longitudinal study of adults aged 50 years and older. Participants completed measures of subjective age, cognitive complaints, and gait speed and provided information on demographic factors, cognition, physical activity, depressive symptoms, and body mass index (BMI) at baseline in 2008/2010. Incident MCR was assessed four and eight years later. RESULTS Controlling for demographic factors, an older subjective age was related to more than 60% higher likelihood of MCR at baseline and to around 50% higher risk of incident MCR over time. These associations remained significant when cognition, physical inactivity, depressive symptoms, and BMI were included in the analytic models. CONCLUSION This study provides evidence that how old individuals feel is related to concurrent and incident MCR beyond the effect of chronological age, other demographic factors, physical inactivity, depressive symptoms, BMI, and cognitive functioning.

Abstract
Although a large body of research has demonstrated the predictive power of subjective ageing for several decisive developmental outcomes, there remains some controversy about whether subjective ageing truly represents a unique construct. Thus, information about the convergent and discriminant validity of different approaches to measuring subjective ageing is still critically needed. Using data from the 2014 wave of the German Ageing Survey, we examined how three established subjective ageing measures (subjective age, global attitude toward own ageing, multidimensional ageing-related cognitions) were inter-related as well as distinct from general dispositions (optimism, self-efficacy) and well-being (negative affect, depressive symptoms, self-rated health). Using correlational and multivariate regression analysis, we found that the three subjective ageing measures were significantly inter-related (r = |.09| to |.30|), and that each measure was distinct from general dispositions and well-being. The overlap with dispositional and well-being measures was lowest for subjective age and highest for global attitudes towards own ageing. The correlation between global attitudes towards own ageing and optimism was particularly striking. Despite the high convergent validity of the different dimensions of ageing cognitions, we nevertheless observed stronger associations between specific dimensions of ageing cognitions with negative affect and self-rated health. We conclude that researchers should be aware of the multidimensional nature of subjective ageing. Furthermore, subjective age appears to be a highly aggregated construct and future work is needed to clarify its correlates and reference points.

Abstract
A number of longitudinal studies have pointed to the long-term impact of different views on aging (VoA) on health in later life, whereas the reverse relationship has rarely been examined. Serious cardiovascular events such as myocardial infarction or stroke are life-threatening events which might in turn lead to changes in VoA. The present longitudinal study examined the effect of a cardiovascular event (CVE) on VoA over a three-year period using pooled data from three waves of the German Ageing Survey (2008, 2011, 2014, age range: 40-95 years). In order to account for alternative explanations for changes in VoA, individuals without CVE (n = 200) were matched to individuals who experienced a CVE (n = 202) using a propensity score matching procedure. Compared to individuals without CVE, individuals who experienced a CVE showed adverse changes in three VoA indicators (self-perceptions of aging as associated with physical losses/with ongoing development; subjective age). These results suggest that CVE can in fact change how individuals view their own aging. According to previous studies, this can lead to future health changes and thus become a health-related downward spiral. Health promotion programs could, therefore, profit by adding specific VoA interventions for individuals who experienced a CVE.

Abstract
Objectives The prevalence of obesity with sarcopenia is increasing in adults aged ≥65 years. This geriatric syndrome places individuals at risk for synergistic complications that leads to long-term functional decline. We ascertained the relationship between sarcopenic obesity and incident long-term impaired global cognitive function in a representative US population. Design A longitudinal, secondary data set analysis using the National Health and Aging Trends Survey. Setting Community-based older adults in the United States. Participants Participants without baseline impaired cognitive function aged ≥65 years with grip strength and body mass index measures. Methods Sarcopenia was defined using the Foundation for the National Institutes of Health Sarcopenia Project grip strength cut points (men <35.5 kg; women <20 kg), and obesity was defined using standard body mass index (BMI) categories. Impaired global cognition was identified as impairment in the Alzheimer's Disease-8 score or immediate/delayed recall, orientation, clock-draw test, date/person recall. Proportional hazard models ascertained the risk of impaired cognitive function over 8 years (referent = neither obesity or sarcopenia). Results Of the 5822 participants (55.7% women), median age category was 75 to 80, and mean grip strength and BMI were 26.4 kg and 27.5 kg/m2, respectively. Baseline prevalence of sarcopenic obesity was 12.9%, with an observed subset of 21.2% participants having impaired cognitive function at follow-up. Compared with those without sarcopenia or obesity, the risk of impaired cognitive function was no different in obesity alone [hazard ratio (HR) 0.98; 95% confidence interval (CI) 0.82-1.16]), but was significantly higher in sarcopenia (HR 1.60; 95% CI 1.42-1.80) and sarcopenic obesity (HR 1.20; 95% CI 1.03-1.40). There was no significant interaction term between sarcopenia and obesity. Conclusions Both sarcopenia and sarcopenic obesity are associated with an increased long-term risk of impaired cognitive function in older adults.

Abstract
OBJECTIVE Cystatin C (CysC) is a marker of kidney function that is relevant for the health and cognition of older adults. Little is known about the link between psychological factors and CysC. Therefore, the present study examined whether subjective age is related to CysC level and changes in CysC over time. METHOD Participants were 5,066 individuals drawn from the Health and Retirement Study aged from 50 to 107 years (60% women, mean age = 69.36 years, SD = 9.54). They provided data on subjective age, demographic covariates, and CysC at baseline. CysC was assessed again 4 years later. RESULTS Analysis revealed that an older subjective age was related to higher level of CysC at baseline and to an increase in CysC over 4 years, controlling for demographic factors. An older subjective age was also related to higher risk of exceeding the clinical threshold of CysC at baseline and 4 years later. Additional analysis revealed that disease burden, depressive symptoms, physical inactivity, and BMI partly mediated these associations. CONCLUSION The present study provides new evidence on the role of subjective age as a psychological factor associated with individuals' risk of kidney dysfunction, an association beyond chronological age.

Abstract
The present study aims to examine how subjective age of older Korean Americans would be affected by functional disability and attitudes toward aging. We hypothesized that (a) both functional disability and attitudes toward aging would have a direct effect on subjective age and (b) the effect of functional disability on subjective age would be mediated by attitudes toward aging. Our analyses of the survey data with 208 community-dwelling Korean Americans aged 60 and older (mean age = 69.6, SD = 7.51) showed that the indirect effect of functional disability on subjective age through attitudes toward aging [-.020 (.009)] was significant (bias-corrected 95% confidence interval [-.039, -.006]). The findings suggest that functional disability fosters negative attitudes toward aging, which in turn leads to the feelings of being older than actual age. Our study suggests ways to preserve and promote positive perceptions of age and aging.

Abstract
Elderly populations in Asian countries are expected to increase rapidly in the next few decades. Older adults, particularly in high-density cities, spend a considerable amount of time in urban green spaces (UGSs). The World Health Organization noted that UGSs are key to improving the age-friendliness of neighborhoods. Thus, it is necessary to design UGSs for the promotion of healthy ageing to enhance preventive healthcare and relieve medical burdens. This study conducted interviews using a questionnaire with a sample size of 326 participants in the cities of Hong Kong (China) and Tainan (Taiwan region). The inter-relationships among the design of UGSs (e.g., spatial distribution and accessibility, characteristics of plants and UGSs), older adults' perceptions on safety and aesthetics quality of UGSs, and their self-reported health conditions (assessed by the self-reported SF-12v2 Health Survey) were investigated with bivariate Spearman rank correlation tests. The results indicate that the duration of visits to UGSs was positively associated with mental health and social functioning, two subscales evaluating health-related quality of life in SF 12v2. The statistical model (moderation analysis) showed that such a correlation was especially significant in women and those with low social support and social capital. A positive relationship was found between the physical health subscale and perceived safety in UGSs. This relationship was stronger among older adults living alone (moderation analysis). Furthermore, the color of plants and maintenance condition of UGSs were significant aspects affecting the subjective assessment of aesthetic quality. This study provides useful information regarding how to plan and design urban green spaces with certain characteristics that could improve the accessibility and aesthetic quality, which are preferred by older adults.

Abstract
OBJECTIVES To determine home-based gait speed performance and its associations with sociodemographic and health-related factors among older adults. DESIGN Cross-sectional analysis of a nationally representative US population sample. SETTING AND PARTICIPANTS Homes of Health and Retirement Study (HRS) participants. METHODS Walk test data measured at home over 2.5 m were aggregated for 6983 individuals, aged ≥65 years (mean age 74.8 ± 6.9 years, 54.2% women), from the 2006 and 2008 HRS waves. Means for gait speed at normal pace were determined for demographic and clinical groupings; association of gait speed with demographic, socioeconomic status, and health factors were examined. Four-year mortality was predicted from baseline slow gait status defined using demographic-based cutoff scores as well as commonly recommended cutoff scores (100 or 60 cm/s). RESULTS Home-based gait speed (cm/s) means were lower for female than male (9.6% difference), older than younger (18.0% difference), African American than white (20.5% difference), and Hispanic than Non-Hispanic (10.3% difference) participants. Differences by age group, race, and ethnicity remained significant within sexes (P < .001). Lower speed was associated with African American race and all health problems; higher speed was associated with higher socioeconomic status and alcohol consumption. Four-year mortality was predicted by slow gait status. Predictive validity was, in general, higher for slow gait cutoff scores defined by demographic characteristics. CONCLUSIONS AND IMPLICATIONS Mean gait speed measured at home differs among older (aged ≥65 years) US resident population groups defined by sex, age, race, ethnicity, health status, and combinations of these factors, and predicts 4-year mortality when substantially slower than group-based norms. These findings may assist researchers and clinicians in determining normal and abnormal gait performance in older adults in community settings.

Abstract
In the past, older adults were traditionally deemed too weak or fragile to participate in high-intensity exercise, but more recent research indicates that not only is high-intensity exercise not dangerous in this population, but it may in fact be a preferable form of exercise over other, less-intense alternatives. However, many seniors still do not participate in high-intensity exercise despite the mounting evidence that it can improve a number of physiological functions and ultimately increase quality of life. As health, sport, and medical professionals, we must continuously ask ourselves how we can apply our lab-based findings in real-life scenarios, and in the case of older adults, we must find a way to circumvent some of their most common reasons for not exercising, which can include a lack of time, a lack of know-how, a lack of motivation, a fear that high-intensity exercise is unsafe, and a perception that high-intensity exercise is too difficult. Therefore, introducing quick, simple, safe, and perceptually easy exercises may result in immediate health and functional benefits and may serve as a gateway exercise to usher older adults into the realm of high-intensity training. Specifically, assisted jumping could serve this purpose. In this article, the ideas behind the theory and practice of assisted jumping are set forth, providing an evidence-based hypothesis from which future researchers can build on to implement high-speed, high-power, high-intensity exercise in older populations in both research and practical settings.

Abstract
The huge inter-individual differences in how people age have prompted researchers to examine whether people's own perception of how old they are-their subjective age-could be a better predictor of relevant outcomes than their actual chronological age. Indeed, how old people feel does predict mortality hazards, and health-related measures such as walking speed may account for this association. In the present study, we extended this line of work by investigating whether subjective age also predicts walking speed and running speed in daily life or whether the predictive effects of subjective age for behavior manifest only within a controlled performance situation. We used data from 80 older participants (age range 62-82 years; M = 69.50, SD = 4.47) from the Berlin Aging Study II (BASE-II). Subjective age was assessed by self-report. Walking speed in the laboratory was measured with the Timed Up and Go test, and walking speed and running speed in real life were measured with an accelerometer. Results showed that compared to participants who felt older, those who felt younger than they actually were indeed walked faster in the laboratory, but they did not walk or run faster in real life. These patterns of results held when age, gender, education, BMI, comorbidity, depression, physical activity, and cognition were covaried. We discuss the role of stereotype threat in accounting for these results.

Abstract
Interest in the quality of life of people with mental disorders living in therapeutic residential care facilities is an important indicator for the evaluation of therapeutic interventions in the area of health. Physical activity can contribute to a good quality of life. This study evaluated the quality of life and levels of physical activity of people living in therapeutic residential care facilities in the metropolitan area of Porto Alegre. This case series study (n = 68) used SF-36, EuroQol and IPAQ and social-demographic questions. The SF-36 results showed that the domain of general health received the lowest scores (57.47 ± 14.27). The highest scores were in terms of social aspects (77.39 ± 20.21) and physical aspects (77.57 ± 39.71). When using EuroQol, at least one problem (mild or extreme) in at least one dimension was evident among 82% of the residents. The physical activity levels showed that most of the participants were insufficiently active (48.5%) and 14.7% were sedentary. The domains of pain and mobility suggested that the residents were not being encouraged enough to perform physical activities. Knowledge about the perceptions of those living in therapeutic residential care facilities is critical in order to establish effective public policies.

Is the relationship between subjective age, depressive symptoms and activities of daily living bidirectional? Soc Sci Med 2018; 214:41-48.

Abstract
OBJECTIVES The aim of the current study was to investigate the prospective association between subjective age and depressive symptoms and activities of daily living (ADLs), and to test for reciprocal relationships. METHODS We used data from 9886 respondents aged 50 years and over who participated in the English Longitudinal Study of Ageing (ELSA). We fitted a series of multiple regression models to analyse the relationships between subjective age, depressive symptoms, and ADL limitations over a four-year period. RESULTS Following adjustment for demographic, social, cognitive, lifestyle, and health factors, we found that having an older subjective age independently predicted increased ADL limitations (B = -0.16, 95% CI -0.25, -0.07) and greater depressive symptoms (B = -0.40, 95% CI -0.57, -0.23). By contrast, we observed no significant associations between depressive symptoms and ADL limitations and future subjective age in the fully-adjusted model. CONCLUSION In conclusion, older subjective age is associated with future depression and functional health, but the reverse pattern is confounded by initial health and social factors. These findings indicate that an individual's age identity may have an important effect on both depressive symptoms and activities of daily living.

Does negative information about aging influence older adults' physical performance and subjective age? Arch Gerontol Geriatr 2018; 78:181-189.

Abstract
This study investigated the way negative stereotypes influence older adults' physical performance and how old they feel mentally and physically. Sixty-four older adults aged 65 years and older performed different physical tasks using a 3D optoelectronic system under a low or high stereotype threat condition. Self-perceptions of aging were considered as a moderator of the effects of threat. Overall, the effects of threat on physical performance were mostly not significant across tasks. However, threat condition influenced older adults' mental subjective age after they had performed the physical tests; people in the high-threat condition felt closer to their chronological age. Threat also influenced participants' physical subjective age, and this effect was moderated by self-perceptions of aging. More precisely, participants in the high-threat condition felt 7% physically older than their chronological age when they had more negative self-perceptions, while participants in the low-threat condition felt 13% younger. No differences emerged for participants who had more positive self-perceptions. The present findings suggest that performing physical tests under stereotype threat might worsen older people's subjective experience of their own aging by making them feel older.

Abstract
While the aging process is a universal phenomenon, people perceive and experience one's aging considerably differently. Subjective age (SA), referring to how individuals experience themselves as younger or older than their actual age, has been highlighted as an important predictor of late-life health outcomes. However, it is unclear whether and how SA is associated with the neurobiological process of aging. In this study, 68 healthy older adults underwent a SA survey and magnetic resonance imaging (MRI) scans. T1-weighted brain images of open-access datasets were utilized to construct a model for age prediction. We utilized both voxel-based morphometry (VBM) and age-prediction modeling techniques to explore whether the three groups of SA (i.e., feels younger, same, or older than actual age) differed in their regional gray matter (GM) volumes, and predicted brain age. The results showed that elderly individuals who perceived themselves as younger than their real age showed not only larger GM volume in the inferior frontal gyrus and the superior temporal gyrus, but also younger predicted brain age. Our findings suggest that subjective experience of aging is closely related to the process of brain aging and underscores the neurobiological mechanisms of SA as an important marker of late-life neurocognitive health.

Abstract
Background Multimorbidity is an important health outcome but is difficult to quantify. We recently developed a multimorbidity-weighted index (MWI) and herein assess its performance in an independent nationally-representative cohort. Methods Health and Retirement Study (HRS) participants completed an interview on physician-diagnosed chronic conditions and physical functioning. We determined the relationship of chronic conditions on physical functioning and validated these weights with the original, independently-derived MWI. We then determined the association between MWI with physical functioning, grip strength, gait speed, basic and instrumental activities of daily living (ADL/IADL) limitations, and the modified Telephone Interview for Cognitive Status (TICS-m) in adjusted models. Results Among 20,509 adults, associations between chronic conditions and physical functioning varied several-fold. MWI values based on weightings in the HRS and original cohorts correlated strongly (Pearson's r = .92) and had high classification agreement (κ statistic = .80, p < .0001). Participants in the highest versus lowest MWI quartiles had weaker grip strength (-2.91 kg, 95% confidence interval [CI]: -3.51, -2.30), slower gait speed (-0.29 m/s, 95% CI: -0.35, -0.23), more ADL (0.79, 95% CI: 0.71, 0.87) and IADL (0.49, 95% CI: 0.44, 0.55) limitations, and lower TICS-m (-0.59, 95% CI: -0.77, -0.41) (all p < .001). We observed monotonic graded relationships for all outcomes with increasing MWI quartiles. Conclusion A multimorbidity index weighted to physical functioning performed nearly identically in a nationally-representative cohort as it did in its development cohorts, confirming broad generalizability. MWI was strongly associated with subjective and objective physical and cognitive performance. Thus, MWI serves as a valid patient-centered measure of multimorbidity, an important construct in research and clinical practice.

Abstract
Personal views on aging, such as age stereotypes and subjective aging, can affect various health outcomes in later life. For the past 20 years or so, a large body of experimental and longitudinal work has provided ample evidence for this connection. Thus, it seems timely to better understand the pathways of this linkage. The majority of existing studies has either focused on age stereotypes or subjective aging. This theoretical paper provides a systematic comparison of major theoretical approaches that offer explanations through which different views on aging may affect health. After a short review of findings on the short- and long-term effects of different views on aging, we describe theoretical approaches that provide explanations of underlying mechanisms for the effect of both uni- and multidimensional views on aging on health outcomes. We compare the specific characteristics of these approaches, provide a heuristic framework and outline recommendations for future research routes. A better understanding of the impact of different views on aging on health outcomes is not only relevant for basic research in life-span developmental psychology, geropsychology and health psychology, it has also implications for intervention research and public health practices.

Abstract
The 2009 Pinelake Health and Rehab Center shooting in Carthage, North Carolina, presents a unique case study for examining the specific considerations for mass violence events in senior living facilities. A variety of factors, including reduced sensory perception, reduced mobility, and cognitive decline, may increase the vulnerability of the populations of senior living facilities during mass violence events. Management of response aspects such as evacuation, relocation, and reunification also require special consideration in the context of mass violence at senior living facilities. Better awareness of these vulnerabilities and response considerations can assist facility administrators and emergency managers when preparing for potential mass violence events at senior living facilities.

Abstract
The aim of the study was to determine whether gait characteristics were associated with endothelial cell inflammation, oxidative stress, and apoptosis and with circulating biomarkers of inflammation and antioxidant capacity in older patients with symptomatic peripheral artery disease (PAD). Gait measurements of 231 symptomatic men and women with PAD were assessed during a 4-m walk test. Patients were further characterized on endothelial effects of circulating factors present in the sera using a cell culture-based bioassay on primary human arterial endothelial cells and on circulating inflammatory and vascular biomarkers. In a multivariate regression model for gait speed, the significant independent variables were age (p < 0.001), intercellular cell adhesion molecule-1 (ICAM-1) (p < 0.001), diabetes (p = 0.003), sex (p = 0.003), and history of cerebrovascular accidents (p = 0.021). In multivariate analyses for gait cadence, the significant independent predictors included high-sensitivity C-reactive protein (HsCRP) (p < 0.001), diabetes (p = 0.001), and hypertension (p = 0.001). In a multivariate regression model for gait stride length, the significant independent variables were HsCRP (p < 0.001), age (p < 0.001), ICAM-1 (p < 0.001), hypertension (p = 0.002), cellular reactive oxygen species production (p = 0.007), and sex (p = 0.008). Higher levels of circulating biomarkers of inflammation and endothelial cell oxidative stress were associated with slower gait speed, slower cadence, and shorter stride length in older symptomatic patients with PAD. Additionally, this profile of impaired gait was more evident in older patients, in women, and in those with diabetes, hypertension, and history of cerebrovascular accidents.

Abstract
INTRODUCTION The paper aims to evaluate the influence of two different demanding cognitive tasks on gait parameters using BTS SMART system analysis. PATIENTS AND METHODS The study comprised 53 postmenopausal women aged 64.5 ± 6.7 years (range: 47-79). For every subject, gait analysis using a BTS SMART system was performed in a dual-task study design under three conditions: (I) while walking only (single task), (II) walking while performing a simultaneous simple cognitive task (SCT) (dual task), and (III) walking while performing a simultaneous complex cognitive task (CCT) (dual task). Time-space parameters of gait pertaining to the length of a single support phase, double support phase, gait speed, step length, step width, and leg swing speed were analyzed. RESULTS Performance of cognitive tests during gait resulted in a statistically significant prolongation of the left (by 7%) and right (by 7%) foot gait cycle, shortening of the length of steps made with the right extremity (by 4%), reduction of speed of swings made with the left (by 11%) and right (by 8%) extremity, and reduction in gait speed (by 6%). CONCLUSIONS Performance of cognitive tests during gait changes its individual pattern in relation to the level of the difficulty of the task.
