RESUMO
Objetivo: Protocolo para avaliar os efeitos de exercícios multicomponentes na capacidade intrínseca de idosos. Metodologia: Pessoas idosas (≥ 60 anos) cadastradas em um programa de treinamento multicomponente de Porto Alegre (RS) serão selecionados para avaliação da capacidade intrínseca nos seus cinco domínios: vitalidade (teste de força de preensão manual (FPM), índice de massa corpórea (IMC) e nutrição) sensorial (perguntas autorrelatadas), psicológico (Escala de Depressão Geriátrica, GDS-15), cognitivo (MoCA teste) e locomotor (teste de sentar e levantar e TUG). A pontuação composta da capacidade intrínseca será realizada por meio da soma dos domínios em escore de 0 a 10 pontos. Ao fim de 12 semanas de intervenção com exercícios multicomponentes, os participantes serão reavaliados. Para comparar os efeitos do treinamento multicomponente na capacidade intrínseca composta e por domínio serão utilizados os testes t de Student e ANOVA para comparar os efeitos de diversos tipos de treinamento. Este estudo foi aprovado pelo Comitê de Ética em Pesquisa sob parecer no 5.517.315. Resultados esperados: Ao fim de 12 semanas de intervenção com os exercícios multicomponentes, esperamos um aumento na pontuação composta da capacidade intrínseca e em seus domínios, especialmente o locomotor. Relevância: O risco de dependência, quedas e mortalidade aumenta com o declínio da capacidade intrínseca, suscitando a necessidade de implementar intervenções para limitar esses desfechos negativos. A prática de exercícios multicomponentes é uma estratégia simples, eficaz, com boa adesão e amplamente recomendada para evitar o declínio da capacidade intrínseca e melhorar a saúde e a funcionalidade das pessoas idosas.

Objective: This is a protocol for assessing the effects of multicomponent exercise on the intrinsic capacity of older adults. Methods: Older adults (≥ 60 years old) will be selected for a multicomponent training program in Porto Alegre, RS, Brazil to evaluate the 5 domains of intrinsic capacity: vitality (handgrip strength, body mass index, and nutrition) sensory perception (self-reported questions), psychology (the 15-item Geriatric Depression Scale), cognition (the Montreal Cognitive Assessment) and locomotion (the sit-to-stand test and the Timed Up and Go test). The composite intrinsic capacity score will be obtained by summing the domains, with total scores ranging from 0 to 10 points. After 12 weeks of the multicomponent exercise intervention, the participants will be reassessed. Student's t-test and ANOVA will be used to compare the effects of different types of training on intrinsic capacity. This study was approved by the research ethics committee of the involved institution. Expected results: After the 12-week multicomponent exercise intervention, we expect scores for composite intrinsic capacity and its domains, especially locomotion, to increase. Relevance: The risk of dependence, falls, and mortality increases with reduced intrinsic capacity, indicating a need for interventions to limit these negative outcomes. Multicomponent exercise, a simple, widely recommended, and effective strategy with good adherence, is designed to prevent intrinsic capacity decline in older people and improve their health and functionality.

Objective @#To examine the association between intrinsic capacity and falls in older adults, so as to provide insights into the risk assessment of falls. @*Methods@#Older adults aged 60 years and above were selected from two districts and one county in Bengbu City, Anhui Province from September 2022 to June 2023 using convenience sampling method. Demographic information, health-related behaviors and incidence of falls among participants were collected through questionnaire surveys. The intrinsic capacity included five dimensions: sensory, motor, vitality, cognition and psychology, which were investigated by the sensory dimension screening scale recommended by the World Health Organization, the Simple Physical Functioning Battery (SPPB), the Micro Nutritional Assessment Scale (MNAS-SF), the Brief Intelligent Mental State Examination Scale (MMSE), and the Center for Evaluation of Streamlined Depression Levels 10-entry scale (CESD-10), respectively. A total score of 1 or more indicated a decrease in intrinsic capacity. The association between intrinsic capacity and falls in older adults was analyzed by a multivariable logistic regression model.@*Results@#A total of 1 950 questionnaires were allocated, and 1 917 were valid, with an effective rate of 98.30%. There were 934 men (48.72%) and 983 women (51.28%), with a mean age of (68.15±3.42) years. There were 1 352 rural residents (70.53%) and 1 431 illiterate and primary school-educated residents (74.65%). In the past year, 347 residents fell, accounting for 18.10%. The median comprehensive score for intrinsic capacity was 1.00 (interquartile range, 2.00) points, and 1 320 had a decrease in intrinsic capacity, accounting for 68.86%. Multivariable logistic regression analysis showed that decline in intrinsic ability was associated with the risk of falls after adjustment for age, gender, educational level, marital status, alcohol consumption and self-rated health status (OR=1.531, 95%CI: 1.408-1.721).@*Conclusion@#Decreased intrinsic capacity in older adults may contribute to an increased risk of falls.
RESUMO
Objective:To use structural equation modeling to identify the indicator variables of intrinsic ability vitality among the elderly population.Methods:The study collected data on seven variables commonly used to measure vitality and mobility, including body mass index, weight loss, calf circumference, grip strength, gait speed at 4 m, up and go, and up and sit, from the comprehensive geriatric assessment(CGA)of patients admitted to the Department of Geriatrics of Beijing Hospital between May 2020 and May 2022.The study used a structural equation model to explore and verify the indicator variables of activity, utilizing exploratory factor analysis, confirmatory factor analysis, and correlation analysis.Results:The study conducted an exploratory factor analysis on seven variables, which resulted in two latent variables named vitality and locomotion.Body mass index, weight loss, and calf circumference were found to reflect vitality, while grip strength, 4 m-walking speed, time up and go test, and standing up and down test were found to reflect locomotion.Confirmatory factor analysis indicated that the measurement model was well-constructed and the indicator variables of vitality and locomotion were reasonably assigned[ χ2/ df=35/13, CFI=0.96, RMSEA(95% CI)=0.06(0.04, 0.08)].Correlation analysis showed that grip strength had a stronger correlation with locomotion-related variables than vitality-related variables( for grip strength and locomotion=0.33, for grip strength and vitality=0.21). Conclusions:The intrinsic ability and vitality of elderly individuals can be assessed through various means, including body mass index, weight loss, and calf circumference.However, grip strength is considered a more appropriate measure for reflecting locomotion rather than overall vitality.
RESUMO
Objective:To examine the influence of handgrip strength(HGS)on the intrinsic capacity(IC)and explore the correlation between HGS and intrinsic capacity subdomains in elderly patients of varying genders.Methods:A cross-sectional study was conducted on 201 inpatients admitted to the Geriatric Department of Zhejiang Hospital from May 2020 to November 2021.The study collected data on the patients' general situation and intrinsic capacity assessment, which included physical function, nutritional status, visual and hearing status, cognitive function, and depressive mood.The patients were grouped based on the number of impaired subdomains of intrinsic capacity.Multivariate ordered Logistic regression analysis was performed to identify the factors influencing the impaired subdomains of intrinsic capacity.The patients were further divided into normal and decreased grip strength groups based on HGS thresholds of less than 26 kg for males and less than 18 kg for females.Binary Logistic regression analysis was then used to investigate the relationship between HGS and the different subdomains of intrinsic capacity among males and females.Results:Among the 201 inpatients, 68 were impaired in 0 to 1 subdomain(33.8%), 103 in 2 to 3 subdomains(51.2%), and 30 in more than 3 subdomains(14.9%).After adjusting for confounding factors using multivariate ordered Logistic regression analysis, the HGS of the 2 to 3 and more than 3 subdomain groups were found to be lower than the 0 to 1 subdomain group( OR=0.957, 95% CI: 0.924-0.993, P=0.019).Among the patients, 117(58.2%)had normal HGS, while 84(41.8%)had decreased HGS.In the binary Logistic regression analysis of older adults, adjusted for confounders, the results indicated that older men with decreased HGS had higher odds of experiencing cognition problems( OR=3.919, 95% CI: 1.301-11.804, P=0.015).Similarly, older women with decreased HGS had higher odds of having locomotion( OR=10.623, 95% CI: 2.374-47.536, P=0.002), vitality( OR=7.386, 95% CI: 1.875-29.095, P=0.004), and cognition( OR=4.835, 95% CI: 1.218-19.196, P=0.025)problems. Conclusions:The key population for intrinsic capacity screening should be elderly patients with decreased HGS.It is important to note that there are differences in the subdomains of impaired intrinsic capacity among elderly individuals with decreased HGS of different genders.As a result, it is crucial to prioritize the development of intervention programs to improve intrinsic capacity based on the specific needs of elderly individuals of different genders.
RESUMO
Objective:To examine the impact of intrinsic capacity(IC), comorbidity, and their interaction on the occurrence of adverse outcomes in community-dwelling older adults.Methods:This 2-year observational cohort study included 230 residents aged 75 and above who lived in the Beijing Taikang Yanyaun community active area from June to August 2018.The study evaluated the IC scale, Charlson comorbidity index(CCI), and activity of daily living(ADL).In September 2020, adverse outcomes such as functional decline(defined as a decline of at least one point on the ADL scores at 2-year follow-up compared with baseline)and falls were assessed.The structure equation model(SEM)path analysis was employed to examine the direct and indirect effects of IC and CCI on adverse outcomes.Results:Among the 212 older adults who completed a 2-year follow-up, aged 75-93(mean age 83.8±4.4)years, 59.4%(126 cases)were female.Out of these participants, 51.4%(109 cases)experienced functional decline and 33.5%(71 cases)had falls.Path analysis revealed that the direct effects of IC on functional decline and falls were significantly positive, with standardized coefficients of 0.430 and 0.369, respectively.However, the effect of CCI was not found to be significant.The multi-variable Logistic regression model showed that the total effect of IC on functional decline and falls remained significantly positive, with values of 1.184 and 0.915, respectively.CCI acted as a mediating factor, with indirect effects on functional decline and falls accounting for 5.4% and 0.8%, respectively.In terms of the relationship between age and adverse outcomes, the indirect effect of IC was significantly higher than that of CCI(functional decline: 0.192 vs.0.037; falls: 0.158 vs.0.017). Conclusions:The maintenance of IC in the health management of community-dwelling older adults should be given more attention as it can significantly affect the incidence of functional decline and falls.Comorbidity, on the other hand, has a weaker influence.
RESUMO
Objective:To investigate the correlation of peripheral blood relative mitochondrial DNA copy number(mtDNAcn)with intrinsic capacity and body composition, and to identify potential biomarkers for healthy aging.Methods:Clinical data of 416 patients admitted to our hospital from September 2019 to June 2021 were consecutively collected.MtDNA was extracted from peripheral blood of these subjects, and mtDNAcn was determined by a real-time fluoresence quantitative reverse transcription-polymerase chain reaction(qRT-PCR). Intrinsic capacity assessment included 5 aspects that were exercise[Morse Fall Scale(MFS), Physiological Frailty Phenotype(PFP), Sarcopenia Questionnaire(SARC-CALF), Short Physical Performance Battery(SPPB), Time Up and Go Test(TUG)]; vitality[Mini Nutritional Assessment(MNA), Multidimensional Prognostic Index(MPI)]; cognition[Mini-Mental State Examination(MMSE)scale]; psychology[Geriatric Depression Scale(GDS), Self-rating Anxiety Scale(SAS)]; sensory capacities[Cumulative Illness Rating Scale-the Comorbidity Index(CIRS-CI)]. To assess body composition, dual-energy X-ray absorptiometry was used to measure body fat, including trunk fat, total body fat, fat in the abdominal region, fat in the buttock region, and then to calculate fat index(FMI)and limb skeletal muscle mass index(ASMI).Results:Spearman correlation analysis showed that mtDNAcn had a negatively correlation with age( r=-0.176, P<0.05). After adjustment for gender and body mass index, partial correlation analysis showed mtDNAcn were still negatively correlated with age( r=-0.144, P<0.05). Furthermore, mtDNAcn was significantly correlated with 4 m gait speed, the scores of SARC-CalF, MFS, MNA, MMSE, MPI and its sub-scale's Activities of Daily Living(ADL)and Short Portable Mental Status Questionnaire(SPMSQ)( r=0.171, -0.207, -0.163, 0.221, 0.184, -0.210, 0.241, -0.269, all P<0.05). After adjustment for age, gender and body mass index, partial correlation analysis showed mtDNAcn still had a significant correlation with gait speed, the scores of MFS, MNA, MPI and SPMSQ( r=0.170, -0.170, 0.148, -0.242, -0.188, all P<0.05). In addition, the Spearman correlation analysis showed that mtDNAcn was positively correlated with FMI, trunk fat, total body fat, abdominal fat and fat in the buttock region( r=0.168, 0.143, 0.175, 0.116, 0.199, all P<0.05). However, after adjustment for age and gender, mtDNAcn was only correlated with FMI, total body fat, fat in the buttock region( r=0.126, 0.131, 0.127, all P<0.05). On the other hand, multiple linear regression analysis showed that mtDNAcn was significantly correlated with age, gait speed, FMI, total body fat, fat in the buttock region, the scores of MFS, PFP, MNA and MPI( β=-0.191, 0.156, 0.126, 0.131, 0.125, -0.119, -0.145, 0.151, -0.171, all P<0.05). Conclusions:MtDNAcn is correlated with physical function, frailty, nutrition, falling, cognition and body composition, and may be considered as a biomarker for the evaluation of the locomotion and vitality of human intrinsic capacity.
RESUMO
In order to cope with increasingly severe global population aging, WHO defines "healthy ageing" as the process of developing and maintaining the functional ability required for healthy living of the elderly.Functional ability is related to the interaction between intrinsic capacity(IC)and the environment.IC refers to the sum of all the physical and mental abilities of the individual.Unlike frailty and disability, IC focuses on the functional aspects of the elderly, longitudinally tracking a person's life, rather than on health conditions of the individual at a certain time.Evaluation of IC, including cognitive function, psychological status, sensory function, vitality and locomotor function, is expected to become crucial to predict outcomes and risks of care dependence in the elderly.Starting from screening for IC declines of the elderly in the community, integrated care is formulated taking older people and their caregivers into consideration to improve the quality of life of the elderly to the greatest extent and reduce the social burden.
RESUMO
Objective:To investigate the prevalence of the decline of intrinsic capacity(IC)and to explore the effect of intrinsic capacity decline on falls and hospital readmission during 1 year follow-up.Methods:A total of 311 elderly patients treated in Geriatrics Department of Zhejiang Hospital were enrolled.General information and intrinsic ability data, including cognitive(simple mental state inventory), motor(Tinetti-Balance Scale and 4 m test), vitality(grip strength and mini-nutrition assessment table), perception(self-rated vision or hearing impairment), and psychosocial(Geriatric depression scale), were collected at admission.Falls and hospital readmission within 1 year after discharge were followed up.Multivariate Logistic regression analysis was used to investigate the relationship of baseline intrinsic ability at admission with falls and hospital readmission during 1-year follow-up.Results:Of 311 elderly hospitalized patients, 282(90.7%)had intrinsic capacity decline.During 1 year follow-up, 38 elderly patients(12.2%)had falls and 69 elderly patients(22.2%)were hospital readmitted.After adjusting for confounding factors such as age, gender, education level, comorbidities, multiple medications, fear of falling, and assistive tool use and so on, Logistic regression analysis showed that decreased balance ability was a risk factor for falls within 1 year in elderly patients( OR=3.515, 95% CI: 1.089-11.346, P=0.036), and slow walking speed was a risk factor for one-year hospital readmission( OR=2.426, 95% CI: 1.181-4.983, P=0.016). Conclusions:Decreased motor capacity is closely associated with falls and hospital readmission within 1 year in older patients.Great attention should be paid to the assessment and intervention of motor ability in elderly patients.
RESUMO
With the increase of the elderly population, health problems of the elderly are more prominent and the health needs of the elderly are more complex and diverse, therefore, how to maintain their physical functional status has become the focus of research. Physical resilience and successful aging are closely related. This article reviews the concept of physical resilience, the relationship between physical resilience and frailty and intrinsic capacity, and its impact on the health status of the elderly. The aim of the article is to provide a reference for the assessment of physiological resilience and the related interventions to promote healthy aging.
RESUMO
ObjectiveTo explore the weights and comprehensive indices of each field of intrinsic capacity of old adults, and the correlation between intrinsic capacity and activities of daily living (ADL). MethodsThe data of 5 506 cases aged more than 60 years in the 2015 China Health and Retirement Longitudinal Study (CHARLS) were used to collect the assessment of intrinsic capacity and the measurement of ADL. The assessment of intrinsic capacity included cognition, motor, vitality, sensory and psychology; while the ADL scale included six indicators, namely dressing, bathing, eating, getting in or out of bed, going to the toilet, and controlling urine and feces. ResultsA total of 1 343 cases were limited in ADL (24.4%). Women, lower education level, older age, the widowed, greater number of chronic diseases, and poorer self-rated health were the factors more likely to be limited in ADL. Principal component analysis showed that the largest weight value was in psychological domain, followed by the cognitive domain, and the lowest weight value was in the motor domain. After controlling for the effects of age, gender, living environment, economic income, education level, marriage, smoking and drinking, number of chronic diseases, and self-rated health, the Logistic regression analysis showed that low exercise capacity (OR = 0.581, 95%CI 0.501 to 0.674), depression (OR = 0.426, 95%CI 0.368 to 0.493), audile and visual impairment (OR = 0.813, 95%CI 0.699 to 0.947; OR = 0.684, 95%CI 0.578 to 0.809), overweight (OR = 1.203, 95%CI 1.014 to 1.428) and obesity (OR = 1.584, 95%CI 1.312 to 1.912) were independent risk factors for ADL limitation in older adults. ConclusionDecrease of intrinsic capacity is a predictor for ADL limitation in older adults.
RESUMO
The global population aging problem is increasingly serious.For this reason, WHO proposed the goal of "Healthy Ageing" in 2015, that is to maintain and develop the functional ability of the individuals in order to achieve happiness in old age.At the same time, WHO introduced the relationship between functional ability, intrinsic capacity and the surrounding environment in which older adults live and acquire assistance, providing a new way for solving population aging. "Decade of Healthy Ageing: Baseline Report" was published by WHO in January 2021.It took advantage of existing national studies on ageing in 42 countries to assess the global status of healthy ageing at the start of the decade.And then it outlooks ten years ahead, to 2030, what level we can achieve, and what needs to improve ten years from now.
RESUMO
This article reviews the concept, evaluation criteria, current situation, influencing factors and the impact on health of intrinsic capacity in the elderly at home and abroad, in order to provide reference for clinical medical staff to improve the elderly′s intrinsic capacity, and actively carry out targeted interventions and related research.
RESUMO
Objective:To investigate the level of intrinsic capacity in community-dwelling elderly people and the influencing factors, in order to provide supporting evidence for the improvement of intrinsic capacity, formulation of management strategies, and promotion of quality of life for the elderly.Methods:A cross-sectional survey was carried out from November 2020 to December 2020 with 236 community-dwelling elderly people in Beijing, who were recruited through a convenience sampling method.The investigation used questionnaires for general data and influencing factors for intrinsic capacity, and the World Health Organization intrinsic capacity questionnaire.Multivariate logistic regression was used to analyze the influencing factors for intrinsic capacity of the elderly.Results:Among 236 community-dwelling elderly people, 132(55.9%)had fair intrinsic capacity(≥4 points)and 104(44.1%)had poor intrinsic capacity(<4 points), with an average score of(3.39±0.95). Multiple Logistic regression analysis results showed that sex( OR=2.005, 95% CI: 1.093-3.676, P=0.025), age( OR=1.727, 95% CI: 1.043-2.860, P=0.034), social participation( OR=0.321, 95% CI: 0.170-0.604, P<0.001), entertainment( OR=2.073, 95% CI: 1.079-3.985, P=0.029), exercise( OR=2.975, 95% CI: 1.761-3.784, P=0.039), sleep( OR=0.508, 95% CI: 0.265-0.973, P=0.041), and emotions( OR=0.436, 95% CI: 0.196-0.970, P=0.042)were influencing factors for intrinsic capacity of community-dwelling elderly people. Conclusions:The intrinsic capacity of community-dwelling elderly people is in the middle range.Sex, age, social participation, entertainment, exercise, sleep, and emotions can affect intrinsic capacity.Therefore, intervention strategies based on influencing factors and improvement of lifestyles can help maintain good intrinsic capacity and reduce adverse effects of major health events.
RESUMO
Background: With demographic shifts, there is an unprecedented increase in noncommunicable diseases, multimorbidity, and geriatric syndromes among older adults, especially in economically weaker sectors. However, there is no socioculturally appropriate tool to screen older adults for age-related health needs, multimorbidity, and geriatric syndromes at their doorstep. Objective: Our objective was to create a self-assessment tool, 搃ntegrated care tool� (ICT), and to assess its psychometric properties by applying it on older adults from multiple settings such as hospital, community, and old-age home (assisted living services). Methods: new questionnaire was developed using standardized procedure including item development, pilot testing, and psychometric validation. After obtaining the institutional ethics committee clearance, data were collected from consenting respondents attending the Outpatient Department of Geriatric Medicine, All India Institute of Medical Sciences, New Delhi, community settings through health camps, and long-term care center, between May 2016 and February 2017. Data were computerized and analyzed by principal component analysis as extraction method and orthogonal varimax as rotation method. Results: The final 30-item questionnaire was arranged into various domains as per rotated component matrix analysis. Overall internal consistency of the final questionnaire, as calculated by Cronbach's alpha, was 0.79, and the measure of sampling adequacy was 0.79. Conclusion: ICT-BRIEF is a simple, self-assessment/caregiver-assisted tool to screen the health needs of older adults. This tool can be validated for developing risk score and scaled up to generate a large database to create elderly centered care plans.
