Petrusevski C, MacDermid JC, Wilson MG, Richardson J. Framing Physical Literacy for Adults Through a Rehabilitation Lens: An Expert Consensus Study. J Aging Phys Act 2024; 32:488-495. [PMID: 38417423 DOI: 10.1123/japa.2023-0095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 11/29/2023] [Accepted: 01/13/2024] [Indexed: 03/01/2024]
Abstract
Research indicates a positive relationship between physical literacy and healthy aging; however, there is no consensus on the components required to become a physically literate adult. The objective of this study was to understand how physical literacy for adults with chronic conditions is characterized from the perspective of healthcare professionals. Physiotherapy leaders and physical literacy researchers within North America were invited to an online consensus panel and presented with questions related to physical literacy and rehabilitation. A nominal group technique was used for idea generation, clarification, and ranking. Confidence and safety with movements, motivation and commitment to physical activity, the ability to self-monitor changes in function, and understanding the benefits of physical activity were key components when defining physical literacy. There is a need to reconceptualize physical literacy to include the rehabilitation needs of adults living with chronic conditions, and to design programs that promote physical literacy to enhance function and mobility.

Age-Dependent Relationship of Physical Inactivity with Incident Cardiovascular Disease: Analysis of a Large Japanese Cohort. Can J Cardiol 2024:S0828-282X(24)00501-4. [PMID: 38906248 DOI: 10.1016/j.cjca.2024.06.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Revised: 06/12/2024] [Accepted: 06/13/2024] [Indexed: 06/23/2024] Open
Abstract
BACKGROUND There have been limited studies examining age-dependent associations between physical inactivity and cardiovascular disease (CVD). We aimed to clarify the age-dependent relationship of physical inactivity with incident CVD. METHODS We analyzed 1,097,424 participants aged 18-105 years without a history of CVD enrolled in the DeSC database (median age, 63 years; 46.4% men). We categorized participants into the following 4 groups based on age: ≤44 years (n=203,835), 45-64 years (n=403,619), 65-79 years (n=437,236), ≥80 years (n=52,734). We used three physical inactivity components gained from the self-reported questionnaire during a health checkup. The outcomes were composite CVD events including myocardial infarction, stroke, and heart failure, and each CVD event. RESULTS During a mean follow-up of 3.2±1.9 years, 81,649 CVD events were observed. The hazard ratios of three physical inactivity components for CVD events increased with age category (P for interaction <0.001). For example, the hazard ratio (95% confidence interval) of physical inactivity defined as not doing light, sweaty exercise for 30 minutes at least twice a week for incident CVD in the groups aged ≤44 years, 45-64 years, 65-79 years, and ≥80 years were 0.97 (0.88-1.05), 1.08 (1.05-1.12), 1.12 (1.10-1.15), and 1.17 (1.12-1.21), respectively (P for interaction <0.001). This association was consistent across subtypes of CVD, including heart failure, myocardial infarction, and stroke. CONCLUSIONS The association of physical inactivity with a higher risk of developing CVD increased with age. Preventive efforts for physical activity optimization may be more valuable in older people.

Abstract
BACKGROUND Altered gait patterns and reduced walking speed are commonly reported in adults with Down syndrome (DS). Research on the effects of DS-specific exercise programmes on adults with DS is lacking. The purpose of this quasi-experimental study was to evaluate the changes in gait deviations and walking speed in adults with DS after a DS-specific exercise programme. METHODS Twenty participants underwent a 12-week, DS-specific exercise programme in a telehealth format. Before and after the intervention, gait deviations were assessed with the Ranchos Los Amigos Observational Gait Analysis form, and comfortable walking speed was evaluated with the 4-m walk test. RESULTS We observed increased comfortable walking speed and reduced gait deviations in the whole gait cycle in adults with DS after the intervention. There were fewer gait deviations during single-leg stance and swing-limb advancement and at the hip, knee and ankle joints after the 12-week exercise programme. CONCLUSIONS Gait speed and observable gait impairments in adults with DS significantly improved following a 12-week telehealth exercise programme.

Abstract
BACKGROUND Walking speed is an important clinical tool in the physical therapy examination of older adults, but not always feasible to measure. Clinicians may be limited by space, a client's functional limitations, or use of telehealth. The Walking Speed Questionnaire (WSQ) can be used to estimate walking speed, but the effects of testing protocols on the accuracy and diagnostic capability of the WSQ have not yet been investigated. OBJECTIVES The purposes of this study were to compare estimated with recorded walking speed and examine effects of start condition and instructions in healthy older adults. METHODS One hundred community dwelling adults 60 years or older were tested. After completing the WSQ, participants performed two trials of six walking conditions that included standing and walking starts under instructions to "walk at a usual pace," "as if crossing a street," and "fast." RESULTS Participants averaged 72.4 (9.6) years of age. The WSQ average walking speed was 1.22 (0.16) m/s and was slower than each condition, p-value = 0.001, except for those performed with instructions to walk at usual pace with both standing, 1.23 (0.29) m/s and walking starts, 1.26 (0.30) m/s. Compared to the usual pace walking start condition, the WSQ sensitivity and specificity were 31% and 94% respectively with an 82% accuracy. A modified cutoff of the WSQ to 1.17 m/s improves sensitivity. CONCLUSIONS If walking testing cannot be performed, the WSQ is a reasonable alternative providing an accurate estimate of a client's walking speed when walking at a usual pace.

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
Sarcopenia has been described as a muscle disease, with multiple adverse consequences on human health. Recommendations aimed at supporting awareness, prevention, early detection and treatment of this disease are needed. This review focuses on the epidemiology, pathophysiology and early detection of elderly sarcopenia. As far as treatment is concerned, physical activity and nutritional support are specifically evaluated. An individually tailored resistance exercise training program appears to be crucial for a positive outcome of the sarcopenia prevention and treatment. The nutritional intervention is mostly based on the supplementation with high-quality proteins (i.e., whey protein) in order to increase the intake of essential amino acids and in particular of leucine. In addition, of relevant importance appears to be the supplementation with vitamin D, with omega-3 fatty acids and probiotics. This review evaluates the results of the most qualified studies on the nutritional supplementation of sarcopenic elderly subjects and shows that promising results have been achieved in community elderly subjects, or subjects followed in rehabilitation centers and in nursing homes, with additional resistance exercise programs.

Abstract
BACKGROUND Kidney failure has been associated with decreased physical capacity, although evidence regarding the physical performance of individuals with earlier stages of chronic kidney disease (CKD) remains limited. METHODS Cross-sectional data were derived from the prospective, population-based Maastricht Study. Multivariate linear regression models were fitted to assess the association of estimated glomerular filtration rate (eGFR) and albuminuria categories with physical performance test outcomes. RESULTS Overall, 7396 participants were included. Compared to eGFR 60-90 ml/min/1.73 m2, values < 60 ml/min/1.73 m2 were associated with significantly shorter 6-min walk distance (β: - 13.04 m, 95% confidence intervals-CI - 19.95; - 6.13), worse timed chair rise stand test time (β: 0.91 s, 95% CI 0.36; 1.47), lower maximal grip (β: - 0.83 kg, 95% CI - 1.50; - 0.15) and elbow flexion (β: - 3.64 Nm, 95% CI - 7.11; - 0.16) strength. Additionally, eGFR > 90 ml/min/1.73 m2 was linked to significantly shorter 6-min walk distance (β: - 6.13 m, 95% CI - 9.44; - 2.82). Urinary albumin excretion > 30 mg/24 h was associated with shorter 6-min walk distance (β: - 12.48 m, 95% CI - 18.28; - 6.68), worse timed chair rise stand test time (β: 0.51 s, 95% CI 0.11; 1.06), lower maximal grip (β: - 1.34 kg, 95% CI - 1.91; - 0.76) and elbow flexion strength (β: - 3.31 Nm, 95% CI - 5.80; - 0.82). CONCLUSIONS Reduced eGFR and higher albuminuria levels were associated with worse physical performance, especially shorter 6-min walk distance and lower muscle strength. The relationship between eGFR and physical function was non-linear, with also high eGFR values being associated with worse performance, especially in the six-minute walk test.

Abstract
The purpose of this study was to examine the effects of far-infrared (FIR) heat on quality of life (QOL) in older adults. Participants were assigned to either a convective heat group (CON) or a convective and FIR group. Participants received six, 30-min heat sessions over the course of three weeks. Pre- and post-assessments included physical measures such as range of motion, gait speed, Timed Up and Go, and hand grip strength. Standardized questionnaires were used to determine pain severity and its interference with daily life, and the impact pain had on overall QOL. Pain severity was significantly reduced (from 3.31 to 2.5, p < .05) in the FIR group from pre-to-post, and pain interference was significantly reduced (from 1.26 to 0.43, p < .05) in the CON group from pre-to-post testing. Findings suggest that heat therapy was successful in reducing pain over time.

Abstract
Background The association between poor gait and functional movement ability and metabolic syndrome (MetS) has been well established in older adults. A continuous cardiometabolic risk score, MetSindex, may more easily identify individuals at risk for cardiometabolic disease who do not yet meet the stringent criteria for a formal MetS diagnosis. Although the association between MetS and gait velocity is well established in older adults, no such relationship has been identified in younger adults; a group experiencing a rapid increase in the development of MetS. Methods MetSindex was determined for 21 young adults using standard procedures. Gait velocity was measured as participants completed a ten-meter walk test. Spatiotemporal parameters of gait were also derived using a motion capture system. Simple linear regression was used to determine the relationship between MetSindex and gait velocity, as well as MetSindex and spatiotemporal parameters of gait. Results There was a large inverse relationship between MetSindex and gait velocity. A large inverse relationship was also observed between MetSindex and cadence, and a large positive relationship was observed between stance time and double limb support time. Conclusions Gait velocity slows in young adults who do not necessarily meet the criterion for positive diagnosis of MetS-but demonstrate an increased risk for MetS and cardiovascular disease through higher MetSindex scores. The mechanism underlying reduced gait velocity may be fewer, but not shorter steps. Determining easy-to-use surrogates of MetS (e.g., gait velocity) may help combat the growing prevalence of MetS by increasing access to preventative approaches.

Abstract
BACKGROUND Navigating your environment requires both straight-line gait as well as turning. Gait speed normative values are well established and utilized in determining a person's functional status, however, it has limitations. This study sought to examine whether turning speed declines with age and how it compared to gait speed age-related decline. METHODS A secondary analysis was performed on 275 community dwelling adults between the ages of 18-88 that performed a timed walking test with an inertial measurement unit on their lumbar spine. Turning speed and walking speed were extracted for each participant. A series of mixed models were compared, and Akaike's Information Criterion was used to determine the best fit model between age and turning speed and age and gait speed. FINDINGS Turning speed and gait speed normative values were reported for each age decade. A linear model with a random intercept of "Condition" was used to assess the relationship between age and turning speed. The results indicated a significant negative relationship between age and turning speed (B = -0.66, p < 0.001). A spline-fit model determined a significant negative relationship between age and gait speed after the age of 65 (B = -0.0097, p = 0.002). The effect of age on gait speed before age 65 was not significant. INTERPRETATION Turning speed significantly declines with age in a linear fashion while gait speed begins to decline after age 65. Turning speed may be more responsive to age than gait speed. More research is needed to determine if the decline in turning speed with age is associated with a decline in function.

Abstract
BACKGROUND Outdoor air pollution has been reported to be associated with frailty (including slow gait speed) in older adults. However, to date, no literature exists on the association between indoor air pollution (eg, unclean cooking fuel use) and gait speed. Therefore, we aimed to examine the cross-sectional association between unclean cooking fuel use and gait speed in a sample of older adults from 6 low- and middle-income countries (China, Ghana, India, Mexico, Russia, and South Africa). METHODS Cross-sectional, nationally representative data from the World Health Organization Study on global AGEing and adult health were analyzed. Unclean cooking fuel use referred to the use of kerosene/paraffin, coal/charcoal, wood, agriculture/crop, animal dung, and shrubs/grass based on self-report. Slow gait speed referred to the slowest quintile based on height, age, and sex-stratified values. Multivariable logistic regression and meta-analysis were done to assess associations. RESULTS Data on 14 585 individuals aged ≥65 years were analyzed (mean [standard deviation] age 72.6 [11.4] years; 45.0% males). Unclean cooking fuel use (vs clean cooking fuel use) was significantly associated with higher odds for slow gait speed (odds ratio = 1.45; 95% confidence interval: 1.14-1.85) based on a meta-analysis using country-wise estimates. The level of between-country heterogeneity was very low (I2 = 0%). CONCLUSIONS Unclean cooking fuel use was associated with slower gait speed among older adults. Future studies of longitudinal design are warranted to provide insight into the underlying mechanisms and possible causality.

Abstract
Older patients are more vulnerable to acute illness or injury because of reduced physiologic reserve associated with aging. Therefore, their assessment in the emergency department (ED) should include not only vital signs and their baseline values but also changes that reflect physiologic reserve, such as mobility, mental status, and frailty. Combining aggregated vitals sign scores and frailty might improve risk stratification in the ED. Implementing these changes in ED assessment may require the introduction of senior-friendly processes to ensure ED treatment is appropriate to the older patients' immediate discomfort, personal goals, and likely prognosis.

Mortality, falls and slow walking speed are predicted by different muscle strength and physical performance measures in women and men. Arch Gerontol Geriatr 2023; 114:105084. [PMID: 37290229 DOI: 10.1016/j.archger.2023.105084] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 05/21/2023] [Accepted: 05/29/2023] [Indexed: 06/10/2023]
Abstract
BACKGROUND Different measures of muscle strength, physical performance and body size/composition are used in various sarcopenia definitions. This study investigated which baseline measures best predict incident mortality and falls, and prevalent slow walking speed in older women and men. MATERIALS AND METHODS Data for 899 women (mean age±standard deviation, 68.7 ± 4.3 years) and 497 men (69.4 ± 3.9 years) from the Dubbo Osteoporosis Epidemiology Study 2, comprising sixty variables for muscle strength (quadriceps strength), physical performance (walking speed, timed up and go (TUG) test, sit to stand (STS) test), body size (weight, height, body mass index) and body composition (lean mass, body fat) were included. Sex-stratified Classification and Regression Tree (CART) analyses calculated baseline variable accuracy for predicting incident mortality and falls, and prevalent slow walking speed (<0.8 m/s). RESULTS Over 14.5 years, 103/899 (11.5%) women and 96/497 (19.3%) men died, 345/899 (38.4%) women and 172/497 (34.6%) men had ≥1 fall, and 304/860 (35.3%) women and 172/461 (31.7%) had baseline slow walking speed (<0.8 m/s). CART models identified age and walking speed adjusted for height as the most important predictors for mortality in women, and quadriceps strength (with adjustments) as the most important predictor for mortality in men. In both sexes, STS (with adjustments) was the most important predictor for incident falls, and TUG test was the most important predictor for prevalent slow walking speed. Body composition measures were not important predictors for any outcome. CONCLUSIONS Muscle strength and physical performance variables and cut points predict falls and mortality differently in women and men, suggesting targeted sex-specific application of selected measures may improve outcome prediction in older adults.

[PMID: 37886687 PMCID: PMC10598773 DOI: 10.3389/fgene.2023.1266158] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 09/29/2023] [Indexed: 10/28/2023] Open
Abstract
Background: Osteoarthritis (OA) is one of the most common joint diseases worldwide, imposing a substantial burden on individuals and society. Numerous pieces of evidence suggest that walking pace (WP) can serve as a predictive indicator for the risk of various diseases, and observational studies have also found a potential link between WP and the risk of OA. However, the causal relationship between WP and the risk of OA remains unclear. Methods: We conducted a mendelian randomization (MR) study using data from the European Genome-wide Association Study, which included WP (including 459,915 participants), OA (including 10,083 cases and 40,425 controls), knee OA (including 24,955 cases and 378,169 controls), and hip OA (including 15,704 cases and 378,169 controls). Single nucleotide polymorphisms (SNPs) associated with WP were utilized to infer causal associations with OA and its subtypes. The Inverse Variance Weighted (IVW) technique served as the primary causal analysis method. Three auxiliary MR methods - MR-Egger, weighted median, and maximum likelihood - were used to substantiate the IVW results. Sensitivity analyses were performed to examine heterogeneity and pleiotropy. In addition, multivariate MR (MVMR) analysis was used to assess causality after adjustment for three potential confounders. Results: According to the results of the IVW method, every 1 standard deviation increased in genetic WP corresponds to an 89% reduction in the risk of OA (odds ratio (OR) = 0.11; 95% confidence interval (CI), 0. 06-0.19; p = 1.57 × 10-13), an 83% reduction in the risk of knee OA (OR = 0.17; 95% CI, 0.11-0.28; p = 2.78 × 10-13), and a 76% reduction in the risk of hip OA (OR = 0.24; 95% CI, 0.14-0.43; p = 1.51 × 10-6). These results were confirmed by the three additional MR methods and validated by the sensitivity analysis. Ultimately, the MVMR analysis confirmed that the role of WP in reducing the risk of OA and its subtypes remains consistent regardless of potential confounders. Conclusion: The results of our MR study highlight a significant causal association between WP and the susceptibility to OA, including its knee and hip subtypes. These findings propose that WP could be utilized as a potential prognostic factor for OA risk.

Abstract
AIM Objective measurements of physcial function, including gait speed, handgrip strength, and the chair stand test, have been shown to have predictive capacity for negative health-related outcomes. The aim of this study was to examine campariatively which of these common assessments may be optimal in terms of their predictive capacity for mortality. METHODS A total of 9834 community-dwelling older women aged 65-89 years from the Study of Osteoporotic Fractures (SOF) were followed for 20 years. Gait speed, handgrip strength, and the chair stand test were measured every 2-4 years on up to 9 visits. All deaths were adjudicated. RESULTS All three measurements of physical function were significantly associated with overall, cardiovascular disease and other mortality. Gait speed had the greatest magnitude of hazard ratios (HRs) for all outcomes of interest. A one-unit standard deviation increase in gait speed was associated with a 33% (HR = 0.67, 95% confidence interval [95% CI]: 0.64-0.70) lower risk for overall mortality, a 31% (HR = 0.69, 95% CI: 0.64-0.73) lower risk for cardiovascular disease mortality, a 15% (HR = 0.85, 95% CI: 0.78-0.92) lower risk for cancer mortality and a 42% (HR = 0.58, 95% CI: 0.55-0.62) lower risk for other mortality. Further examination of gait speed identified two cut-points (0.9 and 0.7 m/s) that were strongly indicative of increased mortality risk. CONCLUSION Our large prospective study indicates that gait speed possesses a better prediction of mortality among older women compared with handgrip strength or the chair stand test. Using cut-points of 0.9 and 0.7 m/s can help identify older women at higher mortality risk, who may benefit from physical function improvement interventions. Geriatr Gerontol Int 2023; 23: 715-721.

Abstract
Background The increasing prevalence of diabetes and its significant impact on mortality and morbidity rates worldwide has led to a growing interest in understanding its common risk factors, particularly in relation to chronic kidney disease (CKD). This research article aims to investigate the shared risk factors between type 1 diabetes (T1D), type 2 diabetes (T2D), and CKD using a Mendelian randomization (MR) design. Methods The study utilized genome-wide association study (GWAS) datasets for T1D, T2D, and CKD from the FinnGen research project. GWAS summary statistics datasets for 118 exposure traits were obtained from the IEU OpenGWAS database. MR analyses were conducted to examine the causal relationships between exposure traits and each of the three outcomes. Multiple methods, including inverse-variance weighted, weighted median, and MR-Egger, were employed for the MR studies. Results Phenome-wide MR analyses revealed that eosinophil percentage exhibited a significant and suggestive causal association with T1D and CKD, respectively, suggesting its potential as a shared risk factor for T1D and CKD. For T2D, 34 traits demonstrated significant associations. Among these 34 traits, 14 were also significantly associated with CKD, indicating the presence of common risk factors between T2D and CKD, primarily related to obesity, height, blood lipids and sex hormone binding globulin, blood pressure, and walking pace. Conclusion This research has uncovered the eosinophil percentage as a potential common risk factor for both T1D and CKD, while also identifying several traits, such as obesity and blood lipids, as shared risk factors for T2D and CKD. This study contributes to the understanding of the common risk factors between diabetes and CKD, emphasizing the need for targeted interventions to reduce the risk of these diseases.

Abstract
This study was carried out using a large cohort (N = 4265; 416 deceased) of older, community-dwelling adults from The Irish Longitudinal Study on Ageing (TILDA). The study compared the performance of a new 3-item health index (HI) with two existing measures, the 32-item frailty index (FI) and the frailty phenotype (FP), in predicting mortality risk. The HI was based on the objective measurement of resting-state systolic blood pressure sample entropy, sustained attention reaction time performance, and usual gait speed. Mortality data from a 12-year follow up period were analyzed using Cox proportional regression. All data processing was performed using MATLAB and statistical analysis using STATA 15.1. The HI showed good discriminatory power (AUC = 0.68) for all-cause mortality, similar to FI (AUC = 0.68) and superior to FP (AUC = 0.60). The HI classified participants into Low-Risk (84%), Medium-Risk (15%), and High-Risk (1%) groups, with the High-Risk group showing a significant hazard ratio (HR) of 5.91 in the unadjusted model and 2.06 in the fully adjusted model. The HI also exhibited superior predictive performance for cardiovascular and respiratory deaths (AUC = 0.74), compared with FI (AUC = 0.70) and FP (AUC = 0.64). The HI High-Risk group had the highest HR (15.10 in the unadjusted and 5.61 in the fully adjusted models) for cardiovascular and respiratory mortality. The HI remained a significant predictor of mortality even after comprehensively adjusting for confounding variables. These findings demonstrate the effectiveness of the 3-item HI in predicting 12-year mortality risk across different causes of death. The HI performed similarly to FI and FP for all-cause mortality but outperformed them in predicting cardiovascular and respiratory deaths. Its ability to classify individuals into risk groups offers a practical approach for clinicians and researchers. Additionally, the development of a user-friendly MATLAB App facilitates its implementation in clinical settings. Subject to external validation in clinical research settings, the HI can be more useful than existing frailty measures in the prediction of cardio-respiratory risk.

Abstract
BACKGROUND The mechanism of gait disorder in patients with cerebral small vessel disease (CSVD) remains unclear. Limited studies have compared the effect of cerebral microbleeds (CMBs) and lacunes on gait disturbance in CSVD patients in different anatomical locations. OBJECTIVE To investigate the relationship of quantitative gait parameters with varied anatomically located MRI imaging markers in patients with CSVD. METHODS Quantitative gait tests were performed on 127 symptomatic CSVD patients all with diffuse distributed white matter hyperintensities (WMHs). CMBs and lacunes in regard to anatomical locations and burdens were measured. The correlation between CSVD imaging markers and gait parameters was evaluated using general linear model analysis. RESULTS Presence of CMBs was significantly associated with stride length (β= -0.098, p = 0.0272) and right step length (β= -0.054, p = 0.0206). Presence of CMBs in basal ganglia (BG) was significantly associated with stride length and step length. Presence of CMBs in brainstem was significantly associated with gait parameters including stride length, step length, step height, and step width. Presence of lacunes in brainstem was significantly associated with gait speed (β= -0.197, p = 0.0365). However, presence of lacunes in the other areas was not associated with worse gait performances. CONCLUSION BG and brain stem located CMBs contributed to gait impairment in symptomatic CSVD patients.

Associations between physical fitness and cardiovascular disease in older adults with intellectual disabilities: Results of the Healthy Ageing and Intellectual Disability study. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2023; 67:547-559. [PMID: 36918714 DOI: 10.1111/jir.13027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 01/23/2023] [Accepted: 02/22/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND Reduced physical fitness is a cardiovascular disease (CVD) risk factor in the general population. However, generalising these results to older adults with intellectual disabilities (ID) may be inappropriate given their pre-existing low physical fitness levels and high prevalence of co-morbidities. Therefore, the aim of this study is to investigate the difference in physical fitness between older adults with ID with and without CVD. METHOD Baseline data of a cohort of older adults with borderline to profound ID (HA-ID study) were used (n = 684; 61.6 ± 8.2 years; 51.3% male). CVD status (coronary artery disease, heart failure, stroke) was obtained from medical files. Cardiorespiratory fitness (10-m incremental shuttle walking test), comfortable and fast gait speed (over 5 m distance) and grip strength (hand dynamometer) were measured. Multivariable linear regression models were used to investigate the association between these physical fitness components and the presence of CVD, adjusted for participant characteristics. RESULTS Of the 684 participants 78 (11.4%) had CVD. Participants with CVD scored lower on cardiorespiratory fitness (-81.4 m, P = 0.002), comfortable gait speed (-0.3 km/h, P = 0.04) and fast gait speed (-1.1 km/h, P = 0.04). No significant differences were found for grip strength (-0.2 kg, P = 0.89). CONCLUSIONS Older adults with CVD had significantly lower physical fitness levels than those without CVD, except for grip strength. Longitudinal research is needed to investigate causality.

Frailty in hypertensive population and its association with all-cause mortality: data from the National Health and Nutrition Examination Survey. Front Cardiovasc Med 2023; 10:945468. [PMID: 37180794 PMCID: PMC10167047 DOI: 10.3389/fcvm.2023.945468] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Accepted: 04/05/2023] [Indexed: 05/16/2023] Open
Abstract
Objectives This study aimed to investigate the relationship between frailty and all-cause mortality in hypertensive population. Methods We used data from the National Health and Nutrition Examination Survey (NHANES) 1999-2002 and mortality data from the National Death Index. Frailty was assessed using the revised version of the Fried frailty criteria (weakness, exhaustion, low physical activity, shrinking, and slowness). This study aimed to evaluate the association between frailty and all-cause mortality. Cox proportional hazard models were used to evaluate the association between frailty category and all-cause mortality, adjusted for age, sex, race, education, poverty-income ratio, smoking, alcohol, diabetes, arthritis, congestive heart failure, coronary heart disease, stroke, overweight, cancer or malignancy, chronic obstructive pulmonary disease, chronic kidney disease, and taking medicine for hypertension. Results We gathered data of 2,117 participants with hypertension; 17.81%, 28.77%, and 53.42% were classified as frail, pre-frail, and robust, respectively. We found that frail [hazard ratio (HR) = 2.76, 95% confidence interval (CI) = 2.33-3.27] and pre-frail (HR = 1.38, 95% CI = 1.19-1.59] were significantly associated with all-cause mortality after controlling for variables. We found that frail (HR = 3.02, 95% CI = 2.50-3.65) and pre-frail (HR = 1.35, 95% CI = 1.15-1.58) were associated with all-cause mortality in the age group ≥65 years. For the frailty components, weakness (HR = 1.77, 95% CI = 1.55-2.03), exhaustion (HR = 2.25, 95% CI = 1.92-2.65), low physical activity (HR = 2.25, 95% CI = 1.95-2.61), shrinking (HR = 1.48, 95% CI = 1.13-1.92), and slowness (HR = 1.44, 95% CI = 1.22-1.69) were associated with all-cause mortality. Conclusion This study demonstrated that frailty and pre-frailty were associated with an increased risk of all-cause mortality in patients with hypertension. More attention should be paid to frailty in hypertensive patients, and interventions to reduce the burden of frailty may improve outcomes in these patients.

Abstract
OBJECTIVE We aimed to investigate the recovery of gait function, muscle strength, and the achievement of an independent gait after lung transplantation (LT) in patients with and without pretransplant extracorporeal membrane oxygenation (ECMO) support. METHODS We retrospectively reviewed the medical records of 33 inpatients who underwent bilateral LT and received physical therapy. We assessed the Functional Ambulatory Category (FAC) and Manual Muscle Test (MMT) scores at baseline, 1 month, and 3 months of rehabilitation and the time it took to achieve a FAC score of 3 within 3 months of LT surgery in ECMO and non-ECMO patients. RESULTS The FAC and MMT scores were generally improved during the first 3 months after LT. The number of patients who achieved a FAC score of 3 at 3 months did not significantly differ between the ECMO and non-ECMO groups (P = .193). At 1 month, significantly fewer patients had reached a FAC of 3 in the ECMO group than in the non-ECMO group (P = .042). There were no significant differences in the FAC (P = .398) and MMT scores (P = .079) at 3 months between the 2 groups. CONCLUSIONS Both groups' gait function and muscle strength were continuously restored 3 months after LT. At 1 month, the gait function was assessed by the FAC score, and the rate to achieve a FAC of 3 was higher in the non-ECMO group than in the ECMO group, but at 3 months, the difference was not significant between the 2 groups.

Abstract
Cardiac stress tests have been widely utilized since the 1960s for the diagnostic and prognostic assessment of patients with suspected coronary artery disease (CAD). Clinical risk is primarily based on assessing the presence and magnitude of inducible myocardial ischemia. However, the primary factors driving mortality risk have changed over recent decades. Factors such as typical angina and inducible ischemia have decreased, whereas the percentage of patients with diabetes, obesity and hypertension have increased. There has also been a marked temporal increase in the percentage of patients who require pharmacologic testing due to inability to perform treadmill exercise at the time of cardiac stress testing and this need has emerged as the most potent predictor of mortality risk in contemporary stress test populations. However, the long-term clinical risk posed by the inability to perform exercise and concomitant CAD risk factors are rarely reflected in the assessment of patients' prognostic risk in cardiac stress test reports. In this review, we suggest that the clinical utility of present-day cardiac stress testing can be improved by developing a more comprehensive assessment that integrates and reports all factors which modulate patients' long-term clinical risk following stress testing. This should include assessment of patients' CAD risk factors, physical activity habits and mobility risks, identification of the reasons why patients could not exercise at the time of cardiac stress testing. In addition, the assessment of four core non-aerobic functional parameters should be considered among patients who cannot exercise: assessment of gait speed, handgrip strength, lower extremity strength, and standing balance.

Abstract
Resistance training (RT) is an often ignored but essential component of physical health.. The functioning of the musculoskeletal system declines with age, resulting in sarcopenia, loss of muscle strength and power, decrease in muscle flexibility and balance. Other pertinent age-related changes include decline in basal metabolic rate, increase in fat mass, and decrease in bone mineral density. Such primary aging can be accentuated by the concomitant presence of comorbid conditions, such as insulin resistance and diabetes, obesity, inflammatory conditions, and physical inactivity (PI). The latter is often promoted by the presence of musculoskeletal conditions, such as osteoarthritis, back pain, and osteoporosis, which are quite common in society. RT can diminish long-term joint stress, "resist" age-related physiological deterioration and improve health outcomes through its ability to increase muscle strength and mass, balance the distribution of forces within a joint, increase basal metabolic rate and bone density, reduce body fat and cardiac risk factors, enhance endothelial function, and promote cognitive function and psychological well-being. Accordingly, health providers should screen for PI, lack of RT, and mobility risks using short screening questions, and employ simple functional tests, when indicated, to evaluate patients for impairment in gait, muscle strength, flexibility, and balance. This review also provides general principles for initiating and conducting RT and provides general and specific examples of resistance training programs, which should be individualized for patients through the evaluation and guidance by appropriate health providers, physical therapists, and certified trainers.

Gait Speed and Cardiovascular Disease by Glycemic Status. Am J Prev Med 2023:S0749-3797(23)00001-6. [PMID: 36759226 DOI: 10.1016/j.amepre.2022.12.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 12/21/2022] [Accepted: 12/21/2022] [Indexed: 02/10/2023]
Abstract
INTRODUCTION The aim of this study was to clarify whether the association of gait speed with the incidence of cardiovascular disease depends on baseline glycemic status. METHODS This retrospective observational cohort study used the Japan Medical Data Center Claims Database between 2005 and 2021 and analyzed 3,090,048 participants without a cardiovascular disease history. The median (IQR) age was 44 (37-53) years, and 1,755,205 of the participants (56.8%) were men. Information on gait speed was obtained from self-reported questionnaires in health checkups. Study participants were categorized according to HbA1c levels (<5.7%, 5.7-6.4%, and ≥6.5%). The primary endpoint was defined as a composite cardiovascular disease outcome that consists of heart failure, myocardial infarction, angina pectoris, and stroke. RESULTS During the mean follow-up period of 1,120±857 days, 116,678 composite cardiovascular disease outcomes were documented. Self-reported fast gait speed was related to a lower risk of developing cardiovascular disease; this relationship was more pronounced with increasing HbA1c levels. Compared with slow gait speed, the hazard ratio (95% CI) of self-reported fast gait speed for cardiovascular disease was 0.935 (0.921-0.949) in participants with an HbA1c <5.7%, 0.911 (0.891-0.932) in participants with an HbA1c of 5.7-6.4%, and 0.846 (0.811-0.883) in participants with HbA1c ≥6.5% (p-value for interaction<0.001). CONCLUSIONS The relationship of subjective gait speed with the risk of cardiovascular disease was amplified in individuals with prediabetes or diabetes mellitus, suggesting that maintaining exercise capacity could be more important in individuals with impaired glucose tolerance for preventing cardiovascular disease.

Abstract
OBJECTIVE This study investigated the individual and combined association of walking pace and grip strength with all-cause mortality in Chilean adults. STUDY DESIGN 8813 participants (54.6 % women) from the MAUCO population-based cohort were included in this prospective study. MAIN OUTCOME MEASURES Individual and combined associations of grip strength (normal or low grip) and walking pace (normal or slow walking) with all-cause mortality were investigated using Cox proportional-hazard models. Analyses were adjusted for sociodemographic, lifestyle, and health-related factors. RESULTS Over a median follow-up of 4.74 years, 151 and 206 participants included in the analyses of walking pace and grip strength died. Individuals with low grip strength had a risk of dying 2.40 times (95 % CI: 1.64 to 3.51) higher than their counterparts with normal grip strength. Similar results were identified for slow walkers (HR: 1.77 [95 % CI: 1.25 to 2.50]). When the two factors were combined and the associations investigated, individuals with normal walking pace but with low grip strength had a higher risk of all-cause mortality than those with normal walking pace and normal grip strength (HR: 3.56 [95 % CI: 1.99 to 6.36]). The associations remained even after including a 1- and 2-year landmark period in the analyses. CONCLUSIONS Slow walking pace and low grip strength were associated with a higher risk of mortality (both in isolation and combined). These factors might be early markers of all-cause mortality, and should be measured more frequently in middle-aged and older adults in clinical practice.

Abstract
BACKGROUND Frailty makes older adults vulnerable to adverse health outcomes and can modify pharmacokinetics and drug exposure. OBJECTIVE We aimed to explore the relationship between different frailty assessments and trough plasma concentrations of direct oral anticoagulants in older patients. METHODS The frailty status of adults aged ≥ 70 years receiving regular direct oral anticoagulant medication was assessed by four different instruments: Fried physical phenotype, Rockwood frailty index, Short Physical Performance Battery, and FRAIL scale. The two performance measures "slow gait speed" and "weak grip strength" were used to build a separate score depending on the number of positive criteria (none, one, two). For each participant, a single steady-state direct oral anticoagulant trough plasma concentration was collected, dose-normalized, and its relationship to the various frailty assessments analyzed. RESULTS Forty-two participants completed the study, with most using apixaban (n = 22). Dose-normalized apixaban trough concentrations were 2.48-fold higher in frail participants (Fried phenotype) than in robust participants (p = 0.009) and correlated positively with Fried physical phenotype (rs = 0.535, p = 0.010) and negatively with Short Physical Performance Battery (rs = - 0.434, p = 0.044). Compared with participants who met none of the criteria "slow gait speed" and "weak grip strength", apixaban trough concentrations were approximately 1.9-fold higher in participants who were positive for one (p = 0.018) or two (p = 0.013) of these measures. CONCLUSIONS In this exploratory study, higher levels of frailty on performance-based frailty assessments were associated with higher apixaban exposure in older adults.

Abstract
OBJECTIVE To clarify the interactive combinations of various clinical factors associated with physical activity (PA) at 2 years after total knee arthroplasty (TKA) using classification and regression tree (CART) analysis. DESIGN A retrospective cohort study. SETTING A single university hospital. PARTICIPANTS 286 patients who underwent TKA (N=286). MAIN OUTCOME MEASURES PA was assessed preoperatively, 3 weeks, and 2 years after TKA. Physical functions, namely, 10 m walking test (10MWT), timed Up and Go test, 1-leg standing time, isometric knee extension and flexion strength, knee joint stability, knee pain, femora-tibial angle, and the passive knee extension and flexion angle, were measured before surgery as a baseline and 3 weeks after TKA as acute phase. CART analysis was conducted to clarify the interactive combinations that accurately predict the PA at 2 years after TKA. RESULTS The results of CART analysis indicated that gait speed (≥1.05 m/s) at the acute phase after TKA was the primal predictor for the postoperative PA at 2 years. The highest postoperative PA at 2 years was determined by gait speed (≥1.05 m/s) and PA (>74.5) at the acute phase. The PA at baseline and at acute phase, as well as the body mass index were also selected as predictors of postoperative PA at 2 years. CONCLUSION The present study suggested that acquiring gait speed (≥1.05 m/s) and PA (>74.5) in the postoperative acute phase is the predictive of a high PA at 2 years after TKA.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:1615. [PMID: 36674369 PMCID: PMC9865582 DOI: 10.3390/ijerph20021615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 01/12/2023] [Accepted: 01/13/2023] [Indexed: 06/17/2023]
Abstract
Appropriate goal setting for frail older adults is important because it drives effective rehabilitation. However, more insights into the types and degrees of frailty and goal-setting trends should be obtained. We conducted a multicenter prospective study to qualitatively examine the relation between each frailty domain (physical, social, and cognitive) and the goals of 201 subjects (median age: 79, 43.8% male) who began rehabilitation at a long-term care prevention facility. Goal setting was determined by the specific, measurable, achievable, relevant, and time to goal (SMART) framework up to three months, categorized according to the International Classification of Functioning, Disability, and Health. The results showed that approximately 90% of the subjects had frailty in at least one domain, and about half had frailties in two or more domains. In total, 176 (87.6%) subjects had goals corresponding to activities and participation. The tendency to set goals to improve mobility was confirmed when the number of overlapping frailties was high, especially those in the physical and social domains. Those with milder frailties were more likely to establish goals targeting improvements in community, social, and civic life. These findings will lead to the development of practical goal-setting guidelines for frail older adults.

Abstract
OBJECTIVES To assess whether frailty can be assessed using a smartphone and whether daily walking speed (DWS) is associated with frailty. DESIGN Cross-sectional study. SETTING Three prefectures (Kanagawa, Saitama and Tokyo) in Japan. PARTICIPANTS The study enrolled 163 participants (65 in the robust group, 69 in the prefrailty group and 29 in the frailty group) by sending letters to house owners aged≥55 years. PRIMARY AND SECONDARY OUTCOME MEASURES The participants downloaded the DWS measurement application on their smartphones, which measured the daily walking (DW) parameters (DWS, step length and cadence) and the Kihon checklist for frailty assessment. The differences in the DW parameters between the robust, prefrailty and frailty groups were examined using one-way analysis of variance. We conducted logistic regression analysis for the Crude model (each DW parameter), model 1 (adjusted for the number of steps) and model 2 (model 1+age, sex and the number of chronic diseases). RESULTS DWS was marginally significantly slower in the frailty group than in the prefrailty and robust group (robust 1.26 m/s vs prefrailty 1.25 m/s vs frailty 1.19 m/s, p=0.060). Step length was significantly smaller in the frailty group than in the robust group (robust 66.1 cm vs prefrailty 65.9 vs frailty 62.3 cm, p<0.01). Logistic regression analysis for the three models revealed that DWS was significantly associated with frailty. CONCLUSIONS DWS measured using the smartphone application was associated with frailty. This was probably due to the shorter step length and body height seen in frail individuals.

Overlapping states of AWGS muscle dysfunction and inverse feasibility of ADL recovery by rehabilitation in older inpatients. Sci Rep 2022; 12:22283.

Abstract
Rehabilitation based on guided walking is effective to recover activity of daily living (ADL) in frail older adults, even octogenarians. However, muscle dysfunction obviously reflects disability, and few studies have focused on ADL recovery by rehabilitation. We employed the state of muscle dysfunctions proposed by the Asian Working Group for Sarcopenia (AWGS) in 2019 and attempted to clarify the relation between the overlapping dysfunctions and the feasibility of ADL recovery after rehabilitation. In total, 297 frail older patients (the mean age: 82.8 years, 46.1% of patients were male) participated in a walking-guided rehabilitation program to achieve the goal of ambulatory discharge. Muscle dysfunction was categorized by four standardized methods at the start of rehabilitation (grip strength, gait speed, time of five sit-to-stand, and short physical performance battery: SPPB), according to the AWGS proposal. ADLs were monitored by Barthel index before admission, at the start of rehabilitation, and at discharge. At least one dysfunction was present in 95.3% of patients. If a single patient had three or more muscle dysfunction, the ADLs recovery was significantly limited (interaction: p < 0.05). The overlapped counts of AWGS muscle dysfunction helps to predict inverse feasibility of ADL recovery in frail older patients through rehabilitation.

Abstract
BACKGROUND While kidney transplantation has favorable outcomes in patients aged 65 years and older, many are not referred for evaluation despite having no contraindications. We wanted to determine whether incorporating geriatrics and geriatric assessments (GA), as part of kidney transplant evaluation at the University of Chicago Medicine, would help identify suitable candidates and improve transplantation outcomes among older adults. METHODS Between 2012 and 2016, as part of their multi-disciplinary transplant evaluation, 171 patients underwent an initial GA with the study geriatrician, who rated them on a five-point scale from "poor" to "excellent," and presented their cases to multidisciplinary transplant review meetings. Patients were followed until June 1st, 2021. Predictor variables included geriatric recommendation, clinical characteristics, and demographics. Outcomes of interest were mortality, receipt of transplant, and waitlist placement. RESULTS Compared to patients rated "poor," "marginal," or "fair," we found that patients that the geriatrician recommended as "good" or "excellent" were more likely to be waitlisted and receive a transplant. Favorably rated patients were also less likely to be removed from the waitlist due to becoming medically unfit, meaning worsening medical morbidity, frailty, and cognitive status. CONCLUSION Including geriatricians to perform GAs as part of the transplant evaluation process can help identify suitable elderly candidates.

Abstract
PURPOSE The loss of skeletal muscle mass and muscle strength is common in patients suffering from chronic kidney disease (CKD) and end-stage renal disease (ESRD) undergoing dialysis. The purpose of this study was to conduct a meta-analysis to explore the relationship between physical functional performance and all-cause mortality in CKD and ESRD patients undergoing dialysis. METHODS A systematic literature search was conducted on an electronic database up to January 2022, and all data were analyzed using RevMan5 (version 5.3). RESULTS Totally, 19 studies involving 6908 patients were enrolled for analysis. Patients with poor physical functional performance in the handgrip strength (HGS) (hazard ratio [HR] = 1.99, P < 0.00001), gait speed (HR = 2.45, P = 0.0005), 6 m walk test (HR = 2.94, P < 0.01), and timed up and go test (HR = 1.69, P = 0.02) showed increased risk of all-cause mortality than those with good physical functional performance. In continuous analyses, both per 1 kg increase in HGS (95% CI 0.94-0.98; P < 0.00001; I2 = 47%) and per 1 SD increase in HGS (HR = 0.47 95% CI 0.35-0.64; P < 0.0001; I2 = 35%) were significantly associated with lower all-cause mortality. CONCLUSION The present meta-analysis demonstrated that poor physical function outcomes, including grip strength, gait speed, 6MWT, and TUG test, were significantly associated with high all-cause mortality in patients with CKD and ESRD.

Abstract
Parkinson's disease (PD) is the fastest-growing neurological disease in the world. A key challenge in PD is tracking disease severity, progression, and medication response. Existing methods are semisubjective and require visiting the clinic. In this work, we demonstrate an effective approach for assessing PD severity, progression, and medication response at home, in an objective manner. We used a radio device located in the background of the home. The device detected and analyzed the radio waves that bounce off people's bodies and inferred their movements and gait speed. We continuously monitored 50 participants, with and without PD, in their homes for up to 1 year. We collected over 200,000 gait speed measurements. Cross-sectional analysis of the data shows that at-home gait speed strongly correlates with gold-standard PD assessments, as evaluated by the Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part III subscore and total score. At-home gait speed also provides a more sensitive marker for tracking disease progression over time than the widely used MDS-UPDRS. Further, the monitored gait speed was able to capture symptom fluctuations in response to medications and their impact on patients' daily functioning. Our study shows the feasibility of continuous, objective, sensitive, and passive assessment of PD at home and hence has the potential of improving clinical care and drug clinical trials.

Abstract
PURPOSE This study aimed 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 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 interval (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.

[PMID: 35995094 DOI: 10.1016/j.jamda.2022.07.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 07/12/2022] [Accepted: 07/14/2022] [Indexed: 10/15/2022]
Abstract
OBJECTIVES Slowness, generally assessed by walking speed (WS), is an estimator of frailty and its outcomes. Because of potential difficulties in assessing WS, the Moberg picking-up test (MPUT) might be an alternative. This study investigated the capacity of slowness measurements (WS and MPUT) to predict nonfatal adverse consequences of frailty: primarily, decline in basic activities of daily living (BADL); and secondarily, decline in instrumental activities of daily living (IADL), fall, hospitalization, and incident disease. DESIGN Observational (prospective longitudinal study). SETTING AND PARTICIPANTS This study used data from the population-based Lausanne cohort 65+. At baseline, 1887 individuals (aged 72-77 years) completed both WS (time to walk 20 m at usual pace) and MPUT (time to pick up 12 objects) assessments. METHODS All outcomes, assessed at 1- and 4-year follow-ups, were entered in separate logistic regression models with adjustment for age, sex, and respective values at baseline. The prediction of all outcomes by either WS or MPUT was assessed using area under the receiver operating characteristic curve and compared by χ2 tests. RESULTS There were positive associations between slowness either assessed by WS [relative risk (RR) = 2.48; P < .001] or MPUT (RR = 1.91; P < .001) and decline in BADL at 1-year follow-up. These associations remained significant at 4-year follow-up for both WS (RR = 2.28; P < .001) and MPUT (RR = 1.95; P < .001). There was no significant difference between predictive values of slow WS and MPUT for decline in BADL at 1-year (P = .328) and 4-year follow-ups (P = .413). The prediction was not significantly different for secondary outcomes, except for decline in IADL for which the prediction was slightly better for WS. CONCLUSIONS AND IMPLICATIONS MPUT may be an alternative measurement of slowness with predictive value of functional decline. No significant difference in predictive capabilities of MPUT and WS for specific adverse consequences of frailty is promising in favor of using MPUT for measuring slowness.

Abstract
Little is known regarding the relationship between self-reported gait speed and the subsequent risk of heart failure (HF) and cardiovascular disease (CVD). We sought to clarify the clinical utility of self-reported gait speed in primary CVD prevention settings. This is an observational cohort study using the JMDC Claims Database, which is an administrative health claims database. Data were collected between January 2005 and April 2020. Medical records of 2,655,359 participants without a prior history of CVD were extracted from the JMDC Claims Database. Gait speed was assessed using information from questionnaires provided at health check-ups, and study participants were categorized into fast or slow gait speed groups. The primary outcome was HF. The secondary outcomes included myocardial infarction (MI), angina pectoris (AP), and stroke. The median age was 45.0 years, and 55.3% of participants were men. 46.1% reported a fast gait speed. The mean follow-up period was 1180 ± 906 days. HF, MI, AP, and stroke occurred in 1.9%, 0.2%, 1.9%, and 1.0% of participants, respectively. Multivariable Cox regression analyses showed that, compared with slow gait speed, fast gait speed was associated with a lower incidence of HF, MI, AP, and stroke. The discriminative predictive ability for HF significantly improved by adding self-reported gait speeds to traditional risk factors (net reclassification improvement 0.0347, p < 0.001). In conclusion, our analysis demonstrated that subjective gait speed could be a simple method to stratify the risk of HF and other CVD events in the general population. Further investigations are required to clarify the underlying mechanism of our results and to develop a novel approach for primary CVD prevention.

The Role of Cognitive Performance and Physical Functions in the Association between Age and Gait Speed: A Mediation Study. Geriatrics (Basel) 2022; 7:geriatrics7040073. [PMID: 35893320 PMCID: PMC9326626 DOI: 10.3390/geriatrics7040073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 07/04/2022] [Accepted: 07/05/2022] [Indexed: 11/30/2022] Open
Abstract
Simple Summary Age and mobility are interrelated. In this context, cognitive performance (CP) and physical functions (PF) play a mediating role. However, these concepts are multifaceted, and their interrelationships need further investigations. Thus, our study aims (1) to investigate the association between CP and PF with GS and (2) to examine whether CP and PF mediate the association between age and GS in a large sample of older Brazilian adults. The findings show that low levels of CP and PF were associated with a greater chance of the older individual presenting a slow GS. Moreover, the mediation model indicated that CP and PF mediated, by approximately 12% and 98%, respectively, the association between age and GS. Abstract Introduction: With vulnerable aging, gait speed (GS) undergoes progressive changes, becoming slower. In this process, cognitive performance (CP) and physical function (PF) both play an important role. This study aims (1) to investigate the association between CP and PF with GS and (2) to examine whether CP and PF mediate the association between age and GS in a large sample of Brazilian older adults. Methods: A cross-sectional study analyzed 697 individuals (mean age 70.35 ± 6.86 years) from the state of Amazonas. The CP was evaluated by the COGTEL test battery, PF by the Senior Fitness Test battery, and GS with the 50-foot Walk Test. Results: Older adults with a lower CP and PF had a 70% and 86% chance of slow GS, respectively. When CP and PF were placed simultaneously as mediators, the direct effect estimated by the model revealed a non-significant relationship between age and GS. Specifically, CP and PF mediated the association between age and GS, at approximately 12% and 98%, respectively. Conclusions: CP and PF show the potential to estimate GS performance among older adults. Moreover, CP and PF indicated a negative and direct association between age and slow GS, especially PF.

Braz J Phys Ther 2022; 26:100431. [PMID: 35944315 PMCID: PMC9379516 DOI: 10.1016/j.bjpt.2022.100431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 06/24/2022] [Accepted: 07/13/2022] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND A better understanding of performance in functional mobility tasks related to the mortality patterns for the different causes of death for the Brazilian older population is still a challenge. OBJECTIVE To analyze if gait speed and chair stand test performance are associated with mortality in older adults, and if the overall mobility status changes the effect of other mortality risk factors. METHODS The data were from SABE (Health, Well-being and Aging Study), a multiple-cohort study conducted in São Paulo, Brazil, with a representative sample of people aged 60 and more. Cox regression models were used to analyze 10-year all-cause and cause-specific mortality with consideration for gait speed and the chair stand test. RESULTS Of the 1411 participants, 26% died during the follow-up. The performance in the chair stand test had a more consistent association with mortality (hazard ratio (HR)=1.03, 95%CI: 1.00, 1.05) than gait speed. Being unable to perform the test also increased the risk to die by all-cause (HR=1.71, 95%CI: 1.21, 2.42) and by diseases of the circulatory system (HR=2.14, 95%CI: 1.25, 3.65). The stratified analysis of mobility performance changed the effects of some of the mortality risk factors, such as cognitive impairment and multimorbidity. CONCLUSIONS The chair stand test could be a better choice than 3-meters walking test as a mortality predictor. In addition, the impact of cognitive decline and multimorbidity were greater among those with reduced mobility, supporting the development of preventive interventions and public policies targeted at more vulnerable groups of older adults.

Abstract
Background Physical frailty is associated with increased risk of falls, hospitalisation and mortality. There is a dearth of information on physical frailty of older adults living in residential aged care. This study aimed to describe physical frailty in aged care residents and investigate possible determinants of frailty. Method A retrospective audit of resident records was undertaken across 14 residential aged care facilities. Data were extracted on all consenting residents who had completed measures relating to frailty (Short Physical Performance Battery SPPB; grip strength). All data of the first record of measures were extracted, resident characteristics, and the time from admission to assessment. Summary statistics were completed. Differences between sub-groups were explored (Mann-Whitney U, Kruskall-Wallis Ranked tests). Associations between variables were explored with Chi-squared and Pearson correlations. Determinants of physical frailty were determined with linear regression analyses. Alpha (2-sided) was 0.05. Results Data were extracted for 1241 residents (67% female), with a mean age of 86.0 (7.6) years. Males had a significantly lower time from admission to assessment of frailty (p ≤ 0.001). The average SPPB score was 4.1 (3.3), 75% of residents were frail and 19% pre-frail. Bivariate analyses indicated no significant relationships between grip strength and SPPB score, but significant differences for grip strength, where males were significantly stronger (males 20.2 ± 8.3 kg; females 12.4 ± 5.4 kg; p ≤ 0.001). There was a significant positive relationship between SPPB total score and grip strength, gender (p ≤ 0.001), and marital status (p = 0.049) and a negative relationship between time from admission to assessment and SPPB total score (p ≤ 0.001). There were significant negative relationships between gender (p ≤ 0.001) and age (p ≤ 0.001), and time from admission to assessment (p ≤ 0.001) with grip strength. Conclusion Older adults living in residential aged care have a high level of physical frailty which may lead to increased risk of adverse outcomes. Time in the residential aged care setting and age appear to predict physical frailty. There is a need for a consistent battery of measures to continually monitor frailty and programs to address the high levels of frailty in residential aged care.

Abstract
INTRODUCTION The World Health Organization has introduced the term 'intrinsic capacity' (IC) as a marker of healthy ageing. However, controversy exists on the definition and assessment of IC. We aimed to review the definitions and methods used for the assessment of IC in older adults. In addition, we proposed a new IC scoring method. METHODS A systematic search was performed in PubMed, Web of Science, Cochrane Library, Scopus and SPORTDiscus (up to February 10th, 2022) for studies assesing IC in older adults (>60 years). RESULTS Thirty-three studies were included. There is overall consensus on the definition of IC as well as on its different dimensions, that is: locomotion, vitality, sensory, cognition and psychological. However, the methods for assessing each of these five dimensions differ substantially across studies and there is no consensus on the best method to compute an eventual global compound score to evaluate IC taking into account all its different dimensions. CONCLUSIONS The IC represents a highly relevant clinical concept that has been unfortunately underutilized. We propose a standardization for the assessment of each dimension of IC, with a global 0 (worst) to 10 (highest) score.

Abstract
We investigated the survival time of each clinical syndrome of frontotemporal dementia (FTD) and the impacts of behavioral and motor features on survival of FTD. A total of 216 patients with FTD [82 behavioral variant FTD (bvFTD), 78 semantic variant primary progressive aphasia (svPPA), 43 non-fluent/agrammatic variant PPA (nfvPPA), 13 FTD-motor neuron disease (MND)] were enrolled from 16 centers across Korea. Behaviors and parkinsonism were assessed using the Frontal Behavioral Inventory and Unified Parkinson’s Disease Rating Scale Part III, respectively. The Kaplan–Meier method was used for the survival analysis and the Cox proportional hazards model was applied for analysis of the effect of behavioral and motor symptoms on survival, after controlling vascular risk factors and cancer. An overall median survival of FTD was 12.1 years. The survival time from onset was shortest for FTD-MND and longest for svPPA. The median survival time of patients with bvFTD was unavailable but likely comparable to that of patients with nfvPPA. In the bvFTD group, negative behavioral symptoms and akinetic rigidity were significantly associated with survival. In the nfvPPA group, the presence of dysarthria had a negative impact on survival. These findings provide useful information to clinicians planning for care.

Abstract
Sarcopenia has been recognized as a muscle disease, with adverse consequences on health. Updated recommendations, aimed at increasing awareness of sarcopenia and its accompanying risks, have been produced to urge the early detection and treatment of this disease. Recommended treatment is based on an individually tailored resistance exercise training program, the optimization of protein intake using high-quality protein sources (i.e., whey protein) in order to provide a high amount of essential amino acids—particularly leucine—and addressing vitamin D deficiency/insufficiency. The purpose of this review is to collate and describe all of the relevant efficacy studies carried out with a muscle-targeted oral nutritional supplementation (MT-ONS)—namely a whey-protein-based, leucine- and vitamin D-enriched formula aimed at optimizing their intake and satisfying their requirements—in different patient populations and clinical settings in order to determine if there is enough evidence to recommend prescription for the treatment of sarcopenia or its prevention in high-risk patient populations. Trials using a MT-ONS with or without a concomitant physical exercise program were systematically searched (up to June 2021), and those addressing relevant endpoints (muscle mass, physical performance and function) were critically reviewed. In total, 10 articles providing efficacy data from eight trials were identified and narratively reviewed. As far as older patients with sarcopenia are concerned, MT-ONS has been pertinently tested in six clinical trials (duration 4–52 weeks), mostly using a high-quality randomized controlled trial design and demonstrating efficacy in increasing the muscle mass and strength, as well as the physical performance versus iso-caloric placebo or standard practice. Consistent results have been observed in various clinical settings (community, rehabilitation centers, care homes), with or without adjunctive physical exercise programs. A positive effect on markers of inflammation has also been shown. A muscle-protein-sparing effect, with benefits on physical performance and function, has also been demonstrated in patients at risk of losing skeletal muscle mass (three trials), such as older patients undergoing weight loss or intensive rehabilitation programs associated with neurological disability (Parkinson’s disease). MT-ONS has demonstrated not only a significant efficacy in clinical variables, but also a positive impact on healthcare resource consumption in the rehabilitation setting (length of stay and duration of rehabilitation). In summary, MT-ONS, alone or in association with an appropriate exercise program, is an effective therapy for older patients with sarcopenia and should be offered as a first-line treatment, not only to improve clinical outcomes but also to reduce healthcare resource consumption, particularly in patients admitted to a rehabilitation center.

Exp Gerontol 2022; 163:111792. [PMID: 35367595 DOI: 10.1016/j.exger.2022.111792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2022] [Revised: 03/20/2022] [Accepted: 03/28/2022] [Indexed: 11/04/2022]
Abstract
OBJECTIVE This umbrella review aimed to summarize the association between modifiable predictive factors and all-cause mortality in the non-hospitalized elderly population, and estimated the credibility and strength of the current evidence. METHODS PubMed, Embase, Web of science, and EBSCOhost were searched up to February 28, 2022. Random-effect summary effect sizes and 95% confidence intervals (CIs), heterogeneity, small-study effect, excess significance bias, as well as 95% prediction intervals (PIs) were calculated. Methodological quality was assessed with the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2) tool. The credibility of the included meta-analyses was graded from convincing to weak using established criteria. This umbrella review was registered with PROSPERO, CRD 42021282183. RESULTS In total, 32 predictive factors involving 49 associations extracted from 35 meta-analyses were analyzed. Forty-three of the 49 (87.8%) associations presented nominal significant effects by the random-effect model (P < 0.05), of which 34 had harmful associations and nine had beneficial associations with all-cause mortality. Frailty (FRAIL scale), low short physical performance battery (SPPB) score, and fewer daily steps carried a more than three-fold risk for all-cause mortality. Convincing evidence showed that weight fluctuation, prefrailty and frailty status, sarcopenia, low SPPB score, fewer daily steps, and fatigue increased the risk of all-cause mortality, while daily moderate-to-vigorous physical activity (MVPA) duration and total physical activity participation reduced the risk of death. There were twenty, nine, five, and six associations that yielded highly suggestive, suggestive, weak, and non-significant grades of evidence. Thirty-four (69.4%) of the associations exhibited significant heterogeneity. Twenty-two associations presented 95% PIs excluding the null value, two indicated small-study effects, and three had evidence for excess significance bias, respectively. The methodological quality of most meta-analyses was rated as low (37.1%) or critically low (42.9%). CONCLUSIONS A summary of the currently available meta-analyses suggests that a broad range of modifiable predictive factors are significantly associated with all-cause mortality risk in the non-hospitalized elderly population. The most credible evidence indicates that physical function represented by frailty and sarcopenia, as well as physical activity, are significant predictors for all-cause mortality. This umbrella review may provide prognostic information to direct appropriate diagnostic evaluation and treatment goals in the future. More solid evidence is still needed coming from moderate-to-high quality meta-analyses.

Abstract
OBJECTIVE Research is limited regarding the predictive utility of the RAND-36 questionnaire and physical performance tests in relation to all-cause, cardiovascular disease (CVD), and total-cancer mortality in older women. METHODS Data on the RAND-36 questionnaire, gait speed, and chair stand performance were assessed in 5,534 women aged ≥ 65 years at baseline. A subset (n = 298) had physical function assessments additionally at follow-up (years 1, 3, or 6). Multivariable Cox proportional hazards regression models estimated associations (HR) for a 1-standard deviation (SD) difference in baseline RAND-36 scores and performance tests (alone and combined) with mortality outcomes in the overall cohort and in models stratified by enrollment age (<70 and ≥70 y). The relative prognostic value of each physical function exposure was assessed using the Uno concordance statistic. RESULTS A total of 1,186 deaths from any cause, 402 deaths from CVD, and 382 deaths from total-cancer were identified during a mean follow-up of 12.6 years. Overall, each 1-SD unit higher baseline RAND-36 score was associated with significantly lower all-cause mortality (HR =0.90) and discriminatory capacity (Uno=0.65) that was comparable to each performance exposure (HRs 0.88-0.91; Uno = 0.65). These findings were consistent in women aged <70 and ≥70 years. The associations of RAND-36 and performance measures with CVD mortality and total-cancer mortality were not significant in multivariable models nor in age-stratified models. CONCLUSIONS The RAND-36 questionnaire is a reasonable substitute for tracking physical functioning and estimating its association with all-cause mortality in older adults when clinical performance testing is not feasible.

Abstract
A decline in functional status, an individual's ability to perform the normal activities required to maintain adequate health and meet basic needs, is part of normal ageing. Functional decline, however, appears to be accelerated in older patients with cancer. Such decline can occur as a result of a cancer itself, cancer treatment-related factors, or a combination of the two. The accelerated decline in function seen in older patients with cancer can be slowed, or even partly mitigated through routine assessments of functional status and timely interventions where appropriate. This is particularly important given the link between functional decline and impaired quality of life, increased mortality, comorbidity burden, and carer dependency. However, a routine assessment of and the use of interventions for functional decline do not typically feature in the long-term care of cancer survivors. This review outlines the link between cancer and subsequent functional decline, as well as potential underlying mechanisms, the tools that can be used to assess functional status, and strategies for its prevention and management in older patients with cancer.

Abstract
INTRODUCTION Dementia and depression often coexist. Understanding how concomitant comorbidities affect function can improve assessment and management strategies. We examined the relationship between cognitive, psychological, and physical function and depressive symptoms in people with cognitive impairment. METHODS Cross-sectional study using baseline data from the iFOCIS randomized controlled trial involving 309 participants with mild-moderate cognitive impairment. The association between cognitive (Addenbrooke's Cognitive Examination-III [ACE-III], Frontal Assessment Battery), psychological (Goldberg Anxiety Scale; Iconographical Falls Efficacy Scale), and physical (Physiological Profile Assessment; Short Physical Performance Battery [SPPB]) function, and quality of life (QoL), physical activity levels and activities of daily living, and depressive symptoms (15-item Geriatric Depression Scale [GDS]) were assessed (adjusted for age, sex, education, and ACE-III as appropriate). RESULTS Participants with depressive symptoms (GDS ≥4) had significantly more falls in the previous year and a higher number of comorbidities than people without depressive symptoms (GDS <4). Each point increase in the GDS was associated with better memory, higher levels of anxiety and concern about falling, poorer balance, slower gait speed, and reduced QoL. The relationship between the GDS and poor balance and QoL withstood additional adjustment for comorbidity tertiles. The relationship between GDS and concern about falls withstood additional adjustment for previous falls (12 months) and SPPB scores. CONCLUSIONS Depressive symptomatology is associated with poorer physical and psychological function and reduced QoL in people with cognitive impairment. These factors should be considered when assessing and intervening in this group. Future research could examine these relationships longitudinally to establish causality and examine intervention efficacy in this group.

Influencing factors for the decline of limb muscle strength and the association with all-cause mortality: evidence from a nationwide population-based cohort study. Aging Clin Exp Res 2022; 34:399-407.

Abstract
BACKGROUND The decline of muscle strength, a typical characteristic of sarcopenia, greatly affects aging-related health outcomes; however, prospective data on influencing factors and mortality in the Chinese population are relatively sparse. AIMS We investigated the influencing factors for the declined limb muscle strength and the association with all-cause mortality among the elderly Chinese individuals aged ≥ 65 years in a large long-term prospective cohort study. METHODS We used data from the China Health and Retirement Longitudinal Study (CHARLS). Logistic regression analyses were performed to investigate the influencing factors of declined limb muscle strength. Cox proportional hazard models were used to analyze the impact on all-cause mortality, whose performance was evaluated by train-test cross-validation. RESULTS The prevalences of declined upper and lower limb strength, which were defined by low hand grip strength (HS) and gait speed (GS), respectively, were 34.4% and 59.7%. The declined HS was significantly associated with older age (p < 0.001), female (p < 0.001), lower educational level (p < 0.001), lower BMI (p < 0.001), and combined with chronic diseases (p = 0.001). Moreover, the declined limb muscle strength was correlated with all-cause mortality (HR: 1.13, 95% CI 1.03-1.21 for HS; HR: 1.09, 95% CI 1.04-1.15 for GS), according to a multi-adjusted model with moderate predictive ability (C-index: 0.714, AUC of 7 year follow-up: 0.716). CONCLUSIONS The decline of limb muscle strength was prevalent among elderly Chinese individuals and had a strong impact on all-cause mortality. Identification of key populations and tailored interventions on their influencing factors should be implemented in further research.

Abstract
Background While there is evidence about stablished risk factors (e.g., raised blood pressure) and higher mortality risk in older population, less has been explored about other functional parameters like the Timed Up and Go test and the Gait Speed in older people at low- and middle-income countries. We aimed to study these mobility tests as predictors of mortality in a population of older people in Peru. Methods Population-based prospective cohort study (2013–2020). Random sampling of people aged 60+ years in a community of Lima, Peru. Geriatricians conducted all clinical evaluations and laboratory tests were conducted in the local hospital. Participants were sought in the national vital registration system, and we collated cause (ICD-10) and date of death. We conducted a nested forward multivariate Cox proportional hazard model to identify all potential predictors of all-cause, communicable and non-communicable diseases mortality. Results At baseline, there were 501 older people (mean age 70.6 and 62.8% were women), complete follow-up information was available from 427 people. Mean follow-up time was 46.5 months (SD = 25.3). In multivariate models, the Timed Up and Go test was associated with higher risk of all-cause mortality (HR = 1.05; 95% CI: 1.02–1.09). For cause-specific mortality, history of heart disease (HR = 2.25; 95% CI: 1.07–4.76) and age in years (HR = 1.05; 95% CI: 1.01–1.09) were predictors of non-communicable diseases mortality. Conclusions In addition to established risk factors for mortality in older population, the Timed Up and Go test, a functional parameter, raised as a relevant predictor of all-cause mortality.
