Yong K, Chew J, Low K, Yeo A, Tan CN, Lim JP, Ding YY, Lim WS. Predictive Validity of Intrinsic Capacity Composite Scores for Risk of Frailty at 2 Years: A Comparison of 4 Scales. J Am Med Dir Assoc 2024:105146. [PMID: 39002555 DOI: 10.1016/j.jamda.2024.105146] [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: 01/20/2024] [Revised: 06/01/2024] [Accepted: 06/04/2024] [Indexed: 07/15/2024]
Abstract
OBJECTIVE Intrinsic capacity (IC) and frailty are complementary constructs that encapsulate functional capacities of older adults. Although earlier studies suggest the utility of composite IC scores in predicting risk of frailty, key gaps remain with the lack of direct comparative studies between different IC scales and lack of a composite score based on the World Health Organization Integrated Care for Older People (ICOPE) tool. We aimed to compare different IC scales, including an ICOPE-based scale, in their predictive ability for risk of frailty at 2 years in healthy community-dwelling older adults. DESIGN Cohort study. SETTING AND PARTICIPANTS A total of 230 participants (age: 67.2 ± 7.4 years) from the GeriLABS-2 cohort study. METHODS We derived composite scores by summing 4 IC domains (locomotion, cognition, vitality, and psychological). We compared composite scores of 4 scales: IC1-Chew 2021, range: 0-8; IC2-Liu 2021, range: 0-4; IC3-ICOPE, range: 0-4; IC4-modified ICOPE, range: 0-8. The primary outcome was risk of frailty using the modified Fried Frailty Phenotype. We performed logistic regression to examine the association of baseline composite IC with risk of frailty. We also examined the impact of individual domains and number of impaired domains on risk of frailty. RESULTS Among 193 (83.9%) older adults who completed 2-year follow-up, 20 (10.4%) met criteria for risk of frailty. When adjusted for covariates, 2-point per domain scales (IC1/IC4) predicted increased risk of frailty (OR, 4.31; 95% CI, 1.55-11.96; OR, 5.00; 95% CI, 1.75-14.26). When further adjusted for baseline frailty, only IC4 remained significant (OR, 4.28; 95% CI, 1.45-12.60). Among the domains, impaired locomotion and vitality were associated with risk of frailty. Greater number of impaired domains predicted increased risk of frailty (IC1/IC2: β = 0.18-0.19, P < .05). CONCLUSIONS AND IMPLICATIONS Baseline composite IC score using 2-point per domain scales better predicted risk of frailty at 2 years, predicated on impaired locomotion/vitality and greater number of impaired domains. For early identification of healthy older adults at risk of frailty, an ICOPE-based scale should be considered, as it is effective and accessible.

Sánchez-Sánchez JL, Lu WH, Gallardo-Gómez D, Del Pozo Cruz B, de Souto Barreto P, Lucia A, Valenzuela PL. Association of intrinsic capacity with functional decline and mortality in older adults: a systematic review and meta-analysis of longitudinal studies. THE LANCET. HEALTHY LONGEVITY 2024; 5:e480-e492. [PMID: 38945130 DOI: 10.1016/s2666-7568(24)00092-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 05/07/2024] [Accepted: 05/08/2024] [Indexed: 07/02/2024] Open
Abstract
BACKGROUND Together with environmental factors, intrinsic capacity (the composite of all the physical and mental capacities of an individual) has been proposed as a marker of healthy ageing. However, whether intrinsic capacity predicts major clinical outcomes is unclear. We aimed to explore the association of intrinsic capacity with functional decline and mortality in older adults. METHODS In this systematic review and meta-analysis, we conducted a systematic search in MEDLINE (via PubMed), Scopus, and Web of Science from database inception to Feb 14, 2024, of observational longitudinal studies conducted in older adults (age ≥60 years) assessing the association of intrinsic capacity with impairment in basic activities of daily living (BADL) or instrumental activities of daily living (IADL) or risk of mortality. Estimates were extracted by two reviewers (JLS-S and W-HL) and were pooled using three-level meta-analytic models. The quality of each study was independently assessed by two authors (JLS-S and PLV) using the Newcastle-Ottawa Scale for longitudinal studies. Heterogeneity was evaluated using the I2 indicator at two levels: within-study (level 2) and between-study (level 3) variation. For associations between intrinsic capacity and IADL and BADL, we transformed data (standardised β coefficients and odds ratios [ORs]) into Pearson product moment correlation coefficients (r) using Pearson and Digby formulas to allow comparability across studies. For associations between intrinsic capacity and risk of mortality, hazard ratios (HRs) with 95% CIs were extracted from survival analyses. This study is registered with PROSPERO, CRD42023460482. FINDINGS We included 37 studies (206 693 participants; average age range 65·3-85·9 years) in the systematic review, of which 31 were included in the meta-analysis on the association between intrinsic capacity and outcomes; three studies (2935 participants) were included in the meta-analysis on the association between intrinsic capacity trajectories and longitudinal changes in BADL or IADL. Intrinsic capacity was inversely associated with longitudinal impairments in BADL (Pearson's r -0·12 [95% CI -0·19 to -0·04]) and IADL (-0·24 [-0·35 to -0·13]), as well as with mortality risk (hazard ratio 0·57 [95% CI 0·51 to 0·63]). An association was also found between intrinsic capacity trajectories and impairment in IADL (but not in BADL), with maintained or improved intrinsic capacity over time associated with a lower impairment in IADL (odds ratio 0·37 [95% CI 0·19 to 0·71]). There was no evidence of publication bias (Egger's test p>0·05) and there was low between-study heterogeneity (I2=18·4%), though within-study (I2=63·2%) heterogeneity was substantial. INTERPRETATION Intrinsic capacity is inversely associated with functional decline and mortality risk in older adults. These findings could support the use of intrinsic capacity as a marker of healthy ageing, although further research is needed to refine the structure and operationalisation of this construct across settings and populations.

Abstract
BACKGROUND The Integrated Care for Older People (ICOPE) approach was developed by the World Health Organization (WHO) aiming to shift the traditional focus of care based on diseases to a function- and person-centered approach, focused on maintaining and monitoring intrinsic capacity (IC). This study aimed to investigate the ability of the ICOPE screening tool to identify older people with clinically meaningful impairments in IC domains. METHODS This cross-sectional analysis included 603 older adults, participants (mean age 74.7 [SD = 8.8] years, women 59.0%) of the INSPIRE Translational (INSPIRE-T) cohort. Responses at screening were compared to results of the subsequent in-depth assessment (ie, Mini-Mental State Examination, Mini Nutritional Assessment, Short Physical Performance Battery, Patient Health Questionnaire-9, and clinical investigation of vision problems) to determine its predictive capacity for impairments at the IC domains (ie, cognition, psychological, sensory (vision), vitality, and locomotion). RESULTS The ICOPE screening items provided very high sensitivity for identifying abnormality in vision (97.2%) and varied from 42.0% to 69.6% for the other domains. High specificity (>70%) was observed for all the IC domains, except for vision (2.7%). CONCLUSIONS The ICOPE screening tool can be a useful instrument enabling the identification of older people with impairments in IC domains, but studies with different populations are needed. It should be considered as a low-cost and simple screening tool in clinical care.

Intrinsic capacity decline as a predictor of functional disability in the elderly: A systematic review and meta-analysis. Arch Gerontol Geriatr 2024; 126:105550. [PMID: 38991290 DOI: 10.1016/j.archger.2024.105550] [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: 02/04/2024] [Revised: 06/13/2024] [Accepted: 06/24/2024] [Indexed: 07/13/2024]
Abstract
OBJECTIVES To examine the predictive value of intrinsic capacity decline on functional disability among the elderly. DESIGN Meta-analysis. METHODS PubMed, EMBASE, Web of Science, The Cochrane Library, Wanfang Database, China Knowledge Resource Integrated Database (CNKI), Weipu Database (VIP), and Chinese Biomedical Database (CBM) were searched for relevant studies published from the inception until June 1, 2024. Stata 17.0 software was used to perform the meta-analysis. The methodological quality was evaluated using the Newcastle Ottawa Scale. The overall quality of evidence used GRADE guidelines to assess. A study protocol was registered in PROSPERO (CRD42023475461). RESULTS The meta-analysis included 8 cohort studies including 9744 elderly people. Functional disability including ADL disability (n = 6) and IADL disability (n = 7). The results showed that intrinsic capacity decline could predict ADL disability (HR = 1.08, 95 %CI 1.04-1.12; I2 = 98.2 %, P < 0.001) and IADL disability (HR = 1.11, 95 %CI 1.05-1.17; I2 = 96.4 %, P < 0.001). The overall risk of bias was low. And the grade of evidence that assessed by GRADE guidelines was rated as moderate. CONCLUSIONS Intrinsic capacity decline is a predictor of functional disability in the elderly. Therefore, screening intrinsic capacity decline has important clinical implications for early identifying the risk of functional disability, which contributes to providing individualized interventions ahead of potential functional disability for the elderly, thereby preventing functional disability, improving the quality of life and promoting healthy aging.

Abstract
BACKGROUND Assessing and monitoring intrinsic capacity (IC) is an effective strategy to promote healthy ageing by intervening early in high-risk populations. This review systematically analyzed the global detection rates of IC deficits and explored variations across diverse populations and data collection methods. METHODS This study was preregistered with PROSPERO, CRD42023477315. In this systematic review and meta-analysis, we systematically searched ten databases from January 2015 to October 2023, for peer-reviewed, observational studies or baseline survey of trials that assessed IC deficits among older adults aged 50 and above globally following the condition, context and population approach. The main outcome was intrinsic capacity deficits which could be assessed by any tools. Meta-analyses were performed by a random-effect model to pool the detection rates across studies and subgroup analyses were conducted by populations and data collection methods. RESULTS Fifty-six studies conducted in 13 countries were included in the review and 44 studies with detection rates of IC were included in the meta-analysis. The pooled detection rate of IC deficits was 72.0% (65.2%-78.8%) and deficits were most detected in sensory (49.3%), followed by locomotion (40.0%), cognition (33.1%), psychology (21.9%), and vitality (20.1%). Variations in detection rates of IC deficits were observed across studies, with higher rates observed in low- and middle-income countries (74.0%) and hyper-aged societies (85.0%). Study population and measurement tools also explained the high heterogeneity across studies. CONCLUSION IC deficits are common among older adults, while heterogeneity exists across populations and by measurement. Early monitoring with standardized tools and early intervention on specific subdomains of IC deficits are greatly needed for effective strategies to promote healthy ageing.

Abstract
OBJECTIVE Frailty has been extensively studied in end-stage kidney disease (ESKD) and kidney transplant (KT) patients. The identification of frailty is useful to predict adverse outcomes among ESKD and KT patients. The recent concept of intrinsic capacity (IC) appears as a good and easy-to-understand tool to screen for and monitor frailty in older adults with ESKD. This study aims to assess the relationships between frailty and IC in older adults with ESKD awaiting KT. DESIGN Cross-sectional study SETTING AND PARTICIPANTS: 236 patients from a day-care geriatric unit undergoing pre-KT geriatric assessment between 2017 and 2022 were included in the main sample, and 151 patients in an independent multicentric replication sample. MEASUREMENTS Frailty was evaluated using the physical frailty phenotype (PFP) and IC measures using the World Health Organization's screening (step 1) and diagnostic (step 2) tools for five IC domains (vitality, locomotion, audition, cognition, psychology). Multivariate regressions were run to assess relationships between PFP and IC domains, adjusted for age, sex, and comorbidities. Analyses were replicated using another independent multicenter cohort including 151 patients with ESKD to confirm the results. RESULTS Impairments in the locomotion, psychology, and vitality IC domains according to WHO screening tools were associated with frailty (odds ratio 9.62 [95% CI 4.09-24.99], 3.19 [95% CI 1.11-8.88], and 3.11 [95% CI 1.32-7.29], respectively). When IC were measured linearly with z-scores, all IC domains except hearing were inversely associated with frailty. In the replication cohort, results were overall similar, with a greater association between psychology domain and frailty. CONCLUSION This study highlights the relationship between frailty and IC in ESKD patients. We assume that IC may be assessed and monitored in ESKD patients, to predict and prevent future frailty, and post-KT adverse outcomes.

Abstract
BACKGROUND Intrinsic capacity (IC) is defined as "all the physical and mental attributes possessed by the older person." This concept has gained momentum in recent years because it provides insights into the changes in the functional capacity of individuals during their life. This study examined common factors associated with IC decline among older adults in Mexico and Colombia. METHODS This cross-sectional, correlational study included 348 community-dwelling older adults. Sociodemographic, clinical, and family conditions were assessed as possible associated factors, and IC was analyzed across five domains: cognitive, locomotor, psychological, vitality (malnutrition through deficiency and excess), and sensory (visual and auditory). Parametric and non-parametric statistical analyses were performed. RESULTS The common factors associated with impairment according to domain were family dysfunctionality (cognitive domain); myocardial infarction, family dysfunctionality, age >80 years, home occupation, and not having a partner (locomotor domain); dysfunctional family and risk of falls (psychological domain); age >80 years and not having a partner (malnutrition by deficiency domain); age 60-79 years, walking <7,500 steps/day, and peripheral vascular disease (malnutrition by excess domain); risk of falling and being female (visual sensory domain); risk of falling (auditory sensory domain); and dysfunctional family and risk of falling (total intrinsic capacity). CONCLUSION Both populations had common sociodemographic, clinical, and familial factors that directly affected total IC stocks and their domains.

Abstract
Background and Purpose Intrinsic capacity (IC) has been shown to have the greatest impact on an individual's health status and health trajectory and can independently predict adverse outcomes such as mortality and care dependency in older adults. However, the current understanding of adverse outcomes associated with IC is incomplete. Methods A scoping review of the literature from PubMed, Web of Science (WOS), The Cochrane Library, CINAHL, and Embase databases was conducted from January 2015 to March 2023 to identify articles related to the adverse outcomes associated with IC in older adults. Results 711 studies met screening criteria, and 25 studies met inclusion criteria. These studies reported a total of 17 adverse outcomes related to IC across four domains. (1) Adverse outcomes in the physiological function domains included frailty, pneumonia onset, memory impairment, polypharmacy, incontinence, and poor/fair self-rated health. (2) Clinical outcomes domains included IADL disability, ADL disability, mortality, falls, autonomy decline, and incident dependence. (3) The resource utilization domains included hospitalization, nursing home stays, polypharmacy healthcare costs, and emergency department visits. (4) The other domains mainly included poor quality of life. Conclusion It is evident that IC decline in older adults is associated with a broad spectrum of adverse outcomes spanning cognitive function, activity ability, sensory perception, physical and mental health and living standards. Future studies should further deepen the exploration of IC.

Intrinsic capacity assessment using World Health Organization Integrated Care for Older People Step 1, and the association with frailty in community dwelling older adults. Geriatr Gerontol Int 2024; 24:457-463. [PMID: 38597589 DOI: 10.1111/ggi.14869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 02/27/2024] [Accepted: 03/27/2024] [Indexed: 04/11/2024]
Abstract
AIM This study aimed to investigate the association between intrinsic capacity (IC) and frailty in community-dwelling older adults. Specifically, we examined the utility of the World Health Organization's Integrated Care for Older People Step 1 screen for identifying frail older persons in the community. METHODS This is a cross-sectional analysis of a community frailty screening initiative. IC loss was ascertained using the World Health Organization's Integrated Care for Older People Step 1 questions. The Clinical Frailty Scale was used to categorize participants as robust (Clinical Frailty Scale S1-3) or frail (Clinical Frailty Scale ≥4). Logistic regression was used to analyze the association of individual and cumulative IC losses with frailty, adjusting for confounders. Additionally, the diagnostic performance of using cumulative IC losses to identify frailty was assessed. RESULTS This study included 1164 participants (28.2% frail). Loss in locomotion (adjusted odds ratio [AOR] 1.47, 95% CI 1.07-2.02), vitality (AOR 1.58, 95% CI 1.04-2.39), sensory (AOR 1.99, 95% CI 1.51-2.64) and psychological capacities (AOR 1.92, 95% CI 1.45-2.56) were significantly associated with frailty. Loss in more than three IC domains was associated with frailty. Using loss in at least three ICs identifies frailty, with sensitivity of 38.6%, specificity of 83.5% and positive predictive value of 47.4%. Using loss in at least four ICs improved specificity to 96.9%, and is associated with the highest positive predictive value of 57.6% and highest positive likelihood ratio of 3.55 for frailty among all cut-off values. The area under the receiver operating characteristic curve was 0.64 (95% CI 0.61-0.68). CONCLUSIONS IC loss as identified through World Health Organization's Integrated Care for Older People Step 1 is associated with frailty community-dwelling older adults. Geriatr Gerontol Int 2024; 24: 457-463.

Abstract
BACKGROUND Intrinsic capacity (IC) is a comprehensive indicator of the overall well-being of older adults, and assessing of IC can help identify early stage of disability and tailor intervention to individual needs. However, there is a lack of effective and simple IC assessment tools. This study aimed to establish predictive scoring algorithms of IC to identify older adults at high risk of impaired functional ability. METHODS We conducted a cross-sectional study in Southern Taiwan, measuring IC using 7 subitems: cognition, locomotion, vitality, vision, hearing, psychological well-being, and medication usage were measured. Functional ability outcomes included frailty, basic activities of daily living, and instrumental activities of daily living (IADL). The capability of 7 domains of IC in predicting functional ability was assessed by multivariable logistic regression. The prediction of capability of scoring algorithms was indicated by receiver operating characteristic (AUC) curves and measures of sensitivity and specificity. RESULTS A total of 1,152 older adults were recruited and analyzed. Locomotion emerged as a significant predictor of IADL disability and worsening frailty. The IC-based weighted scoring algorism for predicting IADL demonstrated satisfactory capability (AUC: 0.80), as did the algorithm for predicting worsening frailty (AUC: 0.90). The optimal cutoff points for predicting IADL disability and frailty worse were estimated respectively at 13 and 16, with sensitivity/specificity values of 0.74/0.75 for the IADL prediction algorithm and 0.92/0.77 for the frailty prediction algorithm. CONCLUSION Our 7-domain IC screening tool proves to be sensitive and practical for early identification of functional disability and frailty among community-dwelling older adults in Taiwan.

Abstract
Background Decline in intrinsic capacity (IC) has been shown to accelerate progression to disability. The study aims to explore association of IC composite score with functional ability, sarcopenia and systemic inflammation in pre-frail older adults. Methods Cross-sectional study of pre-frail older adults ≥60 years old recruited from the community and primary care centers. Composite scores of four domains of IC were measured: locomotion, vitality, cognition and psychological. FRAIL scale was used to define pre-frailty. Muscle mass was measured using the bioelectrical impedance analysis. Systemic inflammation biomarkers [Interleukin-6 (IL-6), Interleukin-10 (IL-10), Tumor Necrosis Factor Alpha (TNF-α), and Growth differentiated factor 15 (GDF-15)] were measured. Participants in the lowest tertile (T1) exhibited greater decline in IC. Results A total of 398 pre-frail older adults were recruited, mean age was 72.7 ± 5.8 years, 60.1% female, education level 7.8 years, and 85.2% were of Chinese ethnicity. A total of 75.1% had decline in locomotion, 40.5% in vitality, 53.2% in cognition and 41.7% in psychological domain. A total of 95% had decline in at least one domain. T1 was significantly associated with ADL impairment (aOR 3.36, 95% CI 1.78-6.32), IADL impairment (aOR 2.37, 95% CI 1.36-4.13), poor perceived health (aOR 0.96, 95% CI 0.95-0.98), fall (aOR 1.63, 95% CI 1.05-2.84), cognitive impairment (aOR 8.21, 95% CI 4.69-14.39), depression (aOR 101.82, 95% CI 33.62-308.37), and sarcopenia (aOR 2.40, 95% CI 1.60-5.45). T1 had significant associations with GDF-15, IL-10, and IL-10 to TNF-α ratio. Conclusion Decline in IC composite score among pre-frail older adults was associated with functional limitation, sarcopenia, and systemic inflammation.

Abstract
Background Information and communication technology (ICT) is a key factor in advancing the implementation of integrated care for older adults in the context of an aging society and the normalization of epidemics. This systematic review aims to comprehensively evaluate the effectiveness of ICT-based integrated care for older adults to provide input for the construction of intelligent integrated care models suitable for the context of an aging population in China. Methods A systematic review and meta-analysis were conducted using PubMed, Web of Science Core Collection, Scopus, MEDLINE, EBSCO, EMBASE, CINAHL with full text, ProQuest, and Cochrane Library databases, along with the Google Scholar search engine, for papers published between January 1, 2000, and July 25, 2022, to include randomized controlled trials and quasi-experimental studies of ICT-based integrated care for older adults. Two reviewers independently performed literature screening, quality assessment (JBI standardized critical appraisal tool), and data extraction. The results were pooled using a random effects model, and narrative synthesis was used for studies with insufficient outcome data. Results We included 32 studies (21 interventions) with a total of 30,200 participants (14,289 in the control group and 15,911 in the intervention group). However, the quality of the literature could be improved. The meta-analysis results showed that ICT-based integrated care significantly improved the overall perceived health status of older adults (n=3 studies, MD 1.29 (CI 0.11 to 2.46), no heterogeneity) and reduced the number of emergency department visits (n=11 studies, OR 0.46 (CI 0.25 to 0.86), high heterogeneity) but had no significant effect on improving quality of life, mobility, depression, hospital admissions and readmissions, or mortality in older adults, with a high degree of study heterogeneity. Narrative analysis showed that the overall quality of care, primary care service use, and functional status of older adults in the intervention group improved, but the cost-effectiveness was unclear. Conclusions ICT-based integrated care is effective in improving health outcomes for older adults, but the quality and homogeneity of the evidence base need to be improved. Researchers should develop intelligent integrated care programs in the context of local health and care welfare provision systems for older adults, along with the preferences and priorities of the older adults.

Abstract
Intrinsic capacity (IC), a function-centered construct, is defined as the composite of all physical and mental capacities of an individual. IC and surrounding environmental factors determine an individual's functional ability to do what they want or feel valued. Current literature lacks evidence on how IC varies throughout adulthood. In this study, we demonstrated a method to establish age-specific and sex-specific reference centiles for IC using the Human Translational Research Cohort of the INSPIRE Platform (975 adults, aged 20-102 years, living in the southwest France, Toulouse area). IC was operationalized as the mean score of the five key domains (cognition, locomotion, psychology, sensory and vitality) and the factor score from a bifactor model, respectively. Both IC operationalizations showed higher IC levels in young and middle age and markedly lower levels after age 65 years, with greater inter-individual variation in old age than in youth. Individuals with IC ≤10th percentile tended to have high comorbidity, prefrailty/frailty, difficulties in basic and instrumental activities of daily living and falls than individuals with IC >90th percentile. These findings suggest that IC reference centiles can help monitor the functional capacity of individuals during aging, similar to tracking children's development with growth charts.

Abstract
Introduction This study explored the associations of intrinsic capacity (IC), fall risk, and frailty in geriatric inpatients. Methods A total of 703 hospitalized patients aged 75 years or older were recruited for this retrospective observational study from Zhejiang Hospital using a comprehensive geriatric assessment. The IC composite score was constructed from the scores of the Chinese version of the Mini-Mental State Examination, Short Physical Performance Battery, Short Form Mini Nutritional Assessment, 15-item Geriatric Depression Scale, and self-reported hearing and vision impairment. Adverse outcomes were recorded as the fall risk and frailty using the Morse Fall Scale and the Clinical Frailty Scale. Spearman's correlation coefficient analyses and multivariate logistic regression models were used to explore the associations between IC, high fall risk, and frailty. Results Declined IC composite scores were associated with increased risks of falls [odds ratio (OR) = 0.64, 95% confidence interval (CI): 0.57-0.72] and frailty (OR = 0.45, 95%CI: 0.37-0.54) among older hospitalized patients after adjusting for the related potential confounders. In addition, decreased cognitive, vitality, locomotion, and psychological scores were associated with increased adverse health conditions, with ORs ranging from 0.26 to 0.70. Vision impairment was observed to increase the risk of frailty (OR = 0.42, 95%CI: 0.23-0.76) after adjusting for the related potential confounders. Discussion This study indicated that declined IC was associated with fall risk and frailty in older inpatients. Further prospective studies are needed to explore the longitudinal associations between baseline IC and subsequent risk of falls and frailty.

Abstract
BACKGROUND AND AIMS Knowledge of how intrinsic capacity (IC) shape functional ability (FA) trajectories in later life remains unclear. We investigated the changes in IC and their impact on 5-years FA trajectories in the Chinese older population. METHODS A total of 1640 older adults from the Rugao Longitudinal Ageing Study were included and analyzed. FA was assessed by The Lawton Instrumental Activities of Daily Living Scale (IADLs). We used cognition, psychology, locomotion, sensory capacity, and vitality to capture the multiple domains of IC according to the ICOPE method. The IC was derived retrospectively from variables collected before this was described by WHO. RESULTS At baseline, a higher IC was associated with higher IADLs (β = 0.98, 95% CI 0.90, 1.06, P < 0.001). Individuals with declines in IC between wave1 and wave2 experienced a faster decline in IADLs over time (β = - 0.28, 95% CI - 0.40, - 0.16, P < 0.001) after considering covariates. One or more impairment IC scores at baseline strongly predicted death (HR = 1.20, 95% CI 1.11, 1.30, P < 0.001). In addition, according to the IC scores at baseline, we stratify IC in low, middle, and high, compared with those in the high IC score, those in the low were associated with a 2.56-fold (95% CI 1.64, 4.01, P < 0.001) higher risk of mortality, after adjustment for variables. CONCLUSION Changes in IC shape FA trajectories. IC impairment is associated with an increased risk of death. Assessing intrinsic capacity would facilitate early identification of older adults at high risk of adverse outcomes and prompt targeted interventions.

Abstract
OBJECTIVES To systematically assess the prevalence of decreased intrinsic capacity in older adults, stratified by relevant factors such as country, sex, sample source, and region. METHODS We conducted a comprehensive search of PubMed, Web of Science, EMBASE, The Cochrane Library, PsychINFO, CINAHL, China Knowledge Resource Integrated Database, Wanfang Database, Weipu Database, and Chinese Biomedical Database to collect studies published on the decline of intrinsic capacity in older adults before February 24, 2023. The results of the study were analyzed using the Stata 15.0 software package, using a random-effects model to estimate the pooled detection rate of decreased intrinsic capacity in older adults. The Joanna Briggs Institute Critical Appraisal Tool was used to assess the quality of all included studies. RESULTS A total of 16 studies (67,881 older adults in 4 countries) were included. The results showed that the pooled detection rate of decreased intrinsic capacity in older adults was 76.1% (95% CI: 68.0%-84.2%). The 16 studies had obvious heterogeneity, and further subgroup analysis showed that the detection rate of decreased intrinsic capacity in older adults was higher in developed countries, females, and hospitals. Thirteen studies found that the pooled detection rate was 73.7% (95%: CI 64.5%-82.8%) for decreased intrinsic capacity in Chinese older adults, with higher rates in mainland China and Hong Kong than in Taiwan. CONCLUSIONS Our study suggests that intrinsic capacity declines more rapidly in older adults. Understanding the degree of decline in the intrinsic capacity of older adults will help to provide an important basis for the formulation and development of care policies for older adults.

Abstract
BACKGROUND The World Health Organization (WHO) has proposed healthy aging framework, supposing that intrinsic capacity (IC), environment and their interaction may have influence on functional ability (FA). It was still unclear how the IC level and age-friendly living environment impact on FA. This study aims to confirm the relationship between the IC level and age-friendly living environment with FA, especially in older adults with low IC. METHODS Four hundred eighty-five community-dwelling residents aged ≥ 60 years were enrolled. IC constructed by locomotion, cognition, psychological, vitality, and sensory domains was assessed using full assessment tools recommended by WHO. Age-friendly living environment was measured with 12 questions adapted from the spatial indicators framework of age-friendly cities. FA was assessed using activities of daily living (ADL) and one question about mobile payment ability. Multivariate logistic regression was used to explore the association between IC, environment and FA. The influence of the environment on electronic payment and ADL under the IC layer was assessed. RESULTS Of 485 respondents, 89 (18.4%) had ADL impairment, and 166 (34.2%) had mobile payment function impairment. Limited IC (odds ratio [OR] = 0.783, 95% confidence interval [CI] = 0.621-0.988) and poor environment (OR = 0.839, 95% CI = 0.733-0.960) were associated with mobile payment ability impairment. Our results suggested that a supportive age-friendly living environment influenced FA was more prominent in older adults with poor IC (OR = 0.650, 95% CI = 0.491-0.861). CONCLUSIONS Our results confirmed IC and the environment had an impact on mobile payment ability. The relationship between environment and FA showed differences according to IC level. These findings suggest that an age-friendly living environment is important to maintain and enhance elders' FA, especially in those with poor IC.

Findings of a population-based longitudinal study. Maturitas 2023; 171:33-39. [PMID: 37001477 DOI: 10.1016/j.maturitas.2023.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 02/08/2023] [Accepted: 03/19/2023] [Indexed: 03/30/2023]
Abstract
BACKGROUND The ecological model of health and ageing has proposed that functional ability (FA) is determined by the interaction between intrinsic capacity (IC) and environmental characteristics. This study empirically examined how social support, as an important social environmental resource, interacts with IC to affect FA trajectories among older adults. METHODS This was a prospective three-wave cohort study with a sample of 775 community-dwelling older adults. Social support, IC and FA were assessed using the Social Support Rating Scale, the revised Integrated Care for Older People screening tool and the Lawton Instrumental Activities of Daily Living Scale, respectively. Latent growth curve models (LGCM) were implemented to test their relationships. RESULTS FA significantly declined over 3 years, and the detrimental effect of impaired IC on the deterioration rate of FA was buffered by subjective support but was aggravated by support utilization and was not changed by objective support. FA decline among older adults with impaired IC was observed in those with low subjective support or with high support utilization but not in those with high subjective support or with low support utilization. Among older adults with intact IC, FA decline was observed in those with low support utilization but not in those with high support utilization or with low or high subjective support. CONCLUSIONS Subjective support may prevent FA decline among older adults with impaired IC, while support utilization may benefit older adults with intact IC but may be detrimental for those with impaired IC. Social support interventions to optimize FA trajectories should improve older adults' perceptions of support and bridge the gap in support utilization among older adults with impaired IC.

Associations between Vitality/Nutrition and the Other Domains of Intrinsic Capacity Based on Data from the INSPIRE ICOPE-Care Program. Nutrients 2023; 15:nu15071567. [PMID: 37049408 PMCID: PMC10096560 DOI: 10.3390/nu15071567] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Revised: 03/19/2023] [Accepted: 03/21/2023] [Indexed: 04/14/2023] Open
Abstract
BACKGROUND The vitality domain of intrinsic capacity (IC) represents the synthesis of biological interactions and metabolism. As part of the Integrated Care for Older People (ICOPE) program developed by the World Health Organization (WHO), vitality focuses on the nutritional status of older adults. The objective of this work was to describe the vitality domain of IC in community-dwelling older people and to examine the associations of the vitality components (appetite loss and weight loss) with the other IC domains assessed within the framework of ICOPE. METHODS Cross-sectional data were obtained between January 2020 and February 2022 through the INSPIRE-ICOPE-Care program, a real-life ICOPE implementation initiative developed in the Occitania region of France. Participants were men and women aged 60 and older, looking for primary care services within the French healthcare system. RESULTS Appetite loss was reported by 14.0% (2013) of the participants, and weight loss by 12.4% (1788). A total of 863 participants (6.01%) declaring weight loss also suffered from appetite loss. In total, 2910 participants (20.27%) screened positive for the domain of vitality. Appetite loss was significantly associated with positive screenings for the domains of cognition (OR = 2.14 [1.84;2.48]), vision (OR = 1.51 [1.28;1.79]), hearing (OR = 1.18 [1.01;1.37]), psychology (OR = 3.95 [3.46;4.52]), and locomotion 'OR = 2.19 [1.91;2.51]). We found significant associations of weight loss with the IC domains of cognition (OR = 1.65 [1.42;1.93]), psychology (OR = 1.80 [1.56;2.07]), locomotion (OR = 1.64 [1.41;1.91]), vision (OR = 1.24 [1.04;1.47]), and hearing (OR = 1.32 [1.12;1.55]). People reporting simultaneous appetite and weight loss showed higher odds of screening positive for psychological (OR = 5.33 [4.53;6.27]) and locomotion impairments (OR = 3.38 [2.88;3.98]). CONCLUSIONS Appetite and weight loss are common among older people and are related to other potential IC impairments, especially psychological and locomotion. Further studies are needed to explore the longitudinal associations of vitality with the incidence of clinically meaningful declines in the other IC domains.

Abstract
OBJECTIVES This review summarizes the measurements of intrinsic capacity in 5 domains across different studies and evaluates the quality of research papers. DESIGN Scoping review of papers written in English and Chinese published in peer-reviewed journals. SETTING AND PARTICIPANTS The intrinsic capacity of older adults was assessed using the multidomain structure (Cognition, Locomotion, Psychological, Sensory and Vitality) proposed by the World Health Organization. METHODS We searched PubMed, MEDLINE, and Web of Science for papers in English, and CNKI, CBM for papers written in Chinese published until September 13, 2022. Both cross-sectional and cohort studies of multidomain measurements of intrinsic capacity were included. Three independent reviewers appraised the quality of studies, and Cohen's kappa was calculated to determine interrater reliability. Data were listed by author, year, setting, country, age range and number of participants, measurement and calculation of intrinsic capacity, and data acquisition method. RESULTS We included 53 studies. Twenty-one studies were of high quality, 31 studies were of moderate quality, and 1 study was of low quality. Measurements of intrinsic capacity and derivation of the summative index score were heterogeneous. Intrinsic capacity was usually assessed in 4 or 5 domains. Sensory was the most frequently overlooked domain or subdivided into vision and hearing in some studies. Indicators of vitality were the most heterogeneous. We also found consistency in heterogeneous measurements. The most common measurements of cognition, locomotion, and psychological capacity were the Mini-Mental State Examination, Short Physical Performance Battery, and Geriatric Depression Scale respectively. Self-reported questionnaires were commonly adopted in sensory domain. The Mini-Nutritional Assessment and grip strength were the most measured indicators of vitality. CONCLUSIONS AND IMPLICATIONS The focus on capacity and disease should be balanced to better promote healthy aging in older adults. Heterogeneity of intrinsic capacity measurements underscores the need for consensus about standardized measurements and calculation procedures.

Abstract
BACKGROUND The trajectory of frailty and intrinsic capacity (IC) often overlap in older adults. Longitudinal analyses of transitions of frailty and IC, and their associations with incident functional decline are limited. The present study aimed to identify transitions of frailty status and IC, and explore associations between transitions of frailty and IC, and future disability among community-dwelling older adults. METHODS In the West China and Aging Trend Study, 808 participants aged ≥ 60 years completed baseline and three years follow-up (frailty, IC and disability assessments). Physical frailty was measured based on Fried phenotype. IC was evaluated by five domains (cognition, locomotion, sensory, psychological, and vitality). Disability was defined as a need for assistance in any items in activity of daily living (ADL) or the instrumental activity of daily living (IADL). Logistic regressions were performed to examine their relationships. RESULTS Four transitions of IC status (kept well: 27.4%, improved: 8.4%, worsened: 35.4%, and kept poor: 28.8%), and two transitions of frailty status (kept not-frail/improved: 93.2%, kept frail/worsened: 6.8%) were identified. Impaired locomotion and vitality at baseline were significantly associated with kept frail or worsened frail. However, impaired sensory and vitality at baseline not frailty status was significantly associated with transitions of IC. Adjusted for covariates and transitions of frailty, kept poor IC was associated with ADL (OR = 2.26, 95%CI = 1.17,4.34) and IADL disability (OR = 3.74, 95%CI = 1.79, 7.82). CONCLUSIONS Transitions of IC, but not frailty were associated with higher risk of incident disability. Baseline locomotion and vitality impairment were associated with worsened or kept frail. Our findings support the WHO's notion of monitoring and optimizing IC to delay deterioration of IC and preventing frailty and disability. CLINICAL TRIAL NUMBER ChiCTR1800018895.

Intrinsic Capacity to Predict Future Adverse Health Outcomes in Older Adults: A Scoping Review. Healthcare (Basel) 2023; 11:healthcare11040450. [PMID: 36832984 PMCID: PMC9957180 DOI: 10.3390/healthcare11040450] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 12/24/2022] [Accepted: 01/10/2023] [Indexed: 02/09/2023] Open
Abstract
OBJECTIVE Intrinsic capacity is recognized as an important determinant of healthy aging and well-being of older adults; however, relatively little is known about the intrinsic capacity of older adults to predict adverse health outcomes. The study aimed to examine which adverse health outcomes of older adults can be predicted by intrinsic capacity. METHODS The study was conducted using the scoping review methodological framework of Arksey and O'Malley. A systematic literature search of nine electronic databases (i.e., Pubmed, Embase, Cochrane library, Web of science, CINAHL, China National Knowledge Infrastructure, VIP, Wanfang, and the Chinese Biological Medical Literature Database) were performed from the database's inception to 1 March 2022. RESULTS Fifteen longitudinal studies were included. A series of adverse health outcomes were assessed, including physical function (n = 12), frailty (n = 3), falls (n = 3), mortality (n = 6), quality of life (n = 2) and other adverse health outcomes (n = 4). CONCLUSIONS Intrinsic capacity could predict some adverse health outcomes of different follow-up times for older adults; however, due to the small number of studies and sample size, more high-quality studies are necessary to explore the longitudinal relationships between intrinsic capacity and adverse health outcomes in the future.

Abstract
BACKGROUND The 5-repetition chair stand test (CST) is increasingly being used to assess locomotion capacity in older adults. However, there is a lack of age-stratified cutoffs for adults aged ≥70 validated against a higher risk of functional loss. METHODS We used 2 population-based studies (Study on global AGEing and adult health in Mexico [SAGE Mexico] and Toledo Study for Healthy Aging [TSHA]) and receiver operating characteristic (ROC) analyses to develop and cross-validate age-stratified chair stand cutoffs with activities of daily living (ADL) disability as the outcome. Then, we used data from an randomized controlled trial (RCT) (Multidomain Alzheimer Preventive Trial [MAPT]) and a frailty day-hospital for external validation with cross-sectional and longitudinal measures of ADL disability. The merged sample of SAGE Mexico and TSHA was n = 1 595; sample sizes for external validation were: MAPT n = 1 573 and Frailty day-hospital n = 2 434. The Cox models for incident disability in MAPT had a mean follow-up of 58.6 months. RESULTS Cutoffs obtained were 14 second (ages 70-79) and 16 second (ages 80+). Those cutoffs identified older adults at higher odds of incident ADL disability odds ratio (OR) = 1.72 (95% confidence interval [CI] 1.06; 2.78) for ages 70-79 and odds ratio (OR) = 2.27 (95% CI 1.07; 4.80) in those aged 80+. Being a slow chair stander according to the cut points was associated with ADL disability in cross-sectional and longitudinal measures. CONCLUSIONS Fourteen- and 16-second cut points for the CST are suitable to identify people at higher risk of functional decline among older adults in Mexico and Toledo, Spain. Adjusting the cut point from 14 to 16 second generally improved the psychometric properties of the test. The validation of these cutoffs can facilitate the screening for limited mobility and the implementation of the Integrated Care for Older People program.

Abstract
OBJECTIVES To evaluate the measurement structure of the ICOPE screening tool (IST) of intrinsic capacity and to find out whether the IST as a global measure adds explanatory power over and above its domains in isolation to predict the occurrence of adverse health outcomes such as dependence and hospitalization in community-dwelling older people. DESIGN Secondary analysis of a cohort study, the Toledo Study of Healthy Ageing. SETTING Province of Toledo, Spain. PARTICIPANTS Community-dwelling older people. MEASUREMENTS Items equal or similar to those of the IST were introduced as a reflective-formative construct in a Structural Equation Model to evaluate its measurement structure and its association with dependence for basic and instrumental activities and hospitalization over a three-year period. RESULTS A total of 1032 individuals were analyzed. Mean age was 73.5 years (sd 5.4). The least preserved indicators were ability to recall three words (18%) and to perform chair stands (54%). Vision and hearing items did not form a single sensory domain, so six domains were considered. Several cognition items did not show sufficiently strong and univocal associations with the domain. After pruning the ill-behaved items, the measurement model fit was excellent (Satorra-Bentler scaled chi-square: 10.3, degrees of freedom: 11, p=0.501; CFI: 1.000; RMSEA: 0.000, 90% CI: 0.000-0.031, p value RMSEA<=0.05: 1; SRMR: 0.055). In the structural model, the cognition domain items were not associated as expected with age (p values 0.158 and 0.293), education (p values 0.190 and 0.432) and dependence (p values 0.654 and 0.813). The IST included as a composite in a model with the individual domains showed no statistically significant associations with any of the outcomes (dependence for basic activities: 0.162, p=0.167; instrumental: -0.052, p=0.546; hospitalization: 0.145, p=0.167), while only the mobility domain did so for dependence (basic: -0.266, p=0.005; instrumental: -0.138, p=0.019). The model fit of the last version was good (Satorra-Bentler scaled chi-square: 52.1, degrees of freedom: 52, p=0.469; CFI: 1.000; TLI: 1.000; RMSEA: 0.01, 90% CI: 0.000-0.02, p value RMSEA<=0.05: 1; SRMR: 0.071). The IST operationalized as the sum of non-impaired domains was not associated after covariate adjustment (dependence for basic activities: -0.065, p=0.356; instrumental: -0.08, p=0.05; hospitalization: -0.003, p=0.949) either. CONCLUSION The cognitive domain of the IST, and probably other of its items, may need a reformulation. A global measure of intrinsic capacity such as the IST does not add explanatory power to the individual domains that constitute it. So far, our results confirm the importance of checking the findings of the IST with a second confirmatory step, as described in the WHO's ICOPE strategy.

Abstract
BACKGROUND Intrinsic capacity (IC) and frailty are complementary in advancing disability prevention through maintaining functionality. OBJECTIVES We examined the relationship between IC and frailty status at baseline and 1-year, and evaluated if IC decline predicts frailty onset among robust older adults. The secondary objectives investigated associations between IC, physical fitness and health-related outcomes. DESIGN Prospective cohort study. SETTING Community-based assessments. PARTICIPANTS Older adults aged>55 years, who were independent in ambulation (walking aids permitted). MEASUREMENTS 5 domains of IC were assessed at baseline: locomotion (Short Physical Performance Battery, 6-minute walk test), vitality (nutritional status, muscle mass), sensory (self-reported hearing and vision), cognition (self-reported memory, age- and education adjusted cognitive performance), psychological (Geriatric Depression Scale-15, self-reported anxiety/ depression). Composite IC (0-10) was calculated, with higher scores representing greater IC. Frailty status was based on modified Fried criteria, with frailty progression defined as incremental Fried score at 1-year. RESULTS 809 participants (67.6+6.8 years) had complete data for all 5 IC domains. 489 (60.4%) participants were robust but only 213 (26.3%) had no decline in any IC domain. Pre-frail and frail participants were more likely to exhibit decline in all 5 IC domains (p<0.05), with decremental composite IC [9 (8-9), 8 (6-9), 5.5 (4-7.5), p<0.001] across robust, prefrail and frail. IC was significantly associated with fitness performance, independent of age and gender. Higher composite IC reduced risk for frailty progression (OR=0.62, 95% CI 0.48-0.80), and reduced frailty onset among robust older adults (OR=0.53, 95% CI 0.37-0.77), independent of age, comorbidities and social vulnerability. Participants with higher IC were less likely to experience health deterioration (OR=0.70, 95% CI 0.58-0.83), falls (OR=0.76, 95% CI 0.65-0.90) and functional decline (OR=0.64, 95% CI 0.50-0.83) at 1-year. CONCLUSION Declining IC may present before frailty becomes clinically manifest, increasing risk for poor outcomes. Monitoring of IC domains potentially facilitates personalized interventions to avoid progressive frailty.

Abstract
The World Health Organization (WHO) recently published guidelines on the implementation of a new Integrated Care for Older People (ICOPE) framework in 2017-2019. It is an integrated care framework for the screening, assessment, and management of intrinsic capacity (IC) declines. We aimed to examine where the early adopters of ICOPE are across the world, how these study teams and sites plan to apply the framework or have applied it, and the lessons learnt for future adopters. We systematically searched electronic medical and social sciences databases and grey literature published between 31 October 2017 and 31 March 2022. Records were systematically selected using precise inclusion criteria. There were 18 ICOPE study teams and sites across the 29 selected records. Of the 18 study teams and sites, seven were in the development stage, seven conducted feasibility studies, and four have commenced implementation of interventions that applied the ICOPE framework. Future ICOPE adopters may need to make certain decisions. These include whether to adopt ICOPE in the community setting or other settings, whether to adopt only Step 1 on IC screening or additional ICOPE Steps, whether the ICOPE IC screening tool requires modifications, and whether to use digital health technology. We propose the key factors needed to make these decisions and future research needed.

Front Med (Lausanne) 2022; 9:1023879. [PMID: 36507507 PMCID: PMC9732451 DOI: 10.3389/fmed.2022.1023879] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2022] [Accepted: 10/26/2022] [Indexed: 11/26/2022] Open
Abstract
Introduction The concept of participation restriction was first described by the World Health Organization in 2001 as a component of The International Classification of Functioning, Disability and Health Framework. Both falls and fear of falling (FOF) are associated with social isolation, depression, anxiety, poor quality of life and cognitive impairment resulting in participation restriction. Life-space mobility (LSM) is an important indicator for participation restriction which depends on multiple inter-related factors. We aimed to determine participation patterns using latent cluster analysis (LCA) in older adults at risk of falls, its relationship with intrinsic capacity (IC) and its risk prediction. Methods Cross-sectional study of 154 community dwelling older adults ≥ 60 years with falls or risk of falls was conducted. Questionnaires were administered on demographics, hearing, LSM, frailty (FRAIL scale), anorexia of aging (SNAQ), cognition (Montreal Cognitive Assessment, MoCA), FOF (Falls Efficacy Scale-International), physical function, and assessment for handgrip strength (HGS), gait speed, 5-times sit to stand (STS), vision and times-up-and-go (TUG) were performed. Six IC domains (vision and hearing, cognition, nutrition, mobility and depression) were measured. Results Three pattern of participation cluster were identified, high (n = 63, 40.9%), moderate (n = 83, 53.9%) and low (n = 8, 33 5.2%). Individuals in the high participation cluster were significantly younger, had higher LSM scores and lower FES-I scores, more robust, fewer ADL and IADL limitations, lower prevalence of low HGS, higher gait speed and shorter TUG. In the fully adjusted model compared to the high participation cluster, moderate participation was significantly associated with low MoCA scores (OR 4.2, 95% CI 1.7-10.4, p = 0.02), poor STS (OR 7.1, 95% CI 3.0-17.0, p < 0.001) whereas low participation was associated with anorexia of aging (OR 9.9, 95% CI 1.6-60.9, p = 0.014), poor STS (OR 19.1, 95% CI 2.0-187.5, p = 0.011) and hearing impairment (OR 9.8, 95% CI 1.4-70.8, p = 0.024). Participants with 3 out of 6 IC decline had a probability of greater than 80% to belong to the low/moderate participation class. Discussion Physical function, cognition, hearing and nutrition were significantly associated with low and/or moderate participation class. Future studies are needed to evaluate improvement in participation of those with falls or at risk for falls through restoration of IC.

Abstract
Background Maintaining the intrinsic capacity (IC) of older inpatients is a novel view in providing person-centered treatments in clinical practice. Uncertainty remains regarding the primary nature of IC among older hospitalized patients. Objectives We aimed to understand the status of IC among older inpatients by a cluster analysis based on IC measurements. Methods This is a cross-sectional study conducted in the geriatric department of Beijing Hospital in China. Older inpatients who were older than 60 years and who underwent comprehensive geriatric assessments were included. The inpatients were classified into subgroups based on 13 measurements of IC according to unsupervised methods (K-means cluster analysis and t-SNE). Subgroup differences were investigated for domains of IC, age, sex, frailty, activities of daily living, and falls. Results A total of 909 inpatients with a mean age of 76.6 years were included. Almost 98% of the inpatients showed IC impairment. Locomotion impairment was the most prevalent problem (91.1%), followed by sensory impairment (61.4%), psychological impairment (57.3%), cognition decline (30.7%), and vitality problem (29.2%). A total of five clusters were obtained by classification: Cluster 1 (56.6% of the participants) showed high IC with fair impairment of locomotion and vision; clusters 2 and 3 (37.8 % of the participants) had additional impairment of sleep in the psychological domain; clusters 4 and 5 (5.6% of the participants) represented a severe loss of all the IC domains; and clusters 1-5 showed a gradual decline in the IC score and were significantly associated with increased age, frailty, decreased activities of daily living, and falls. Significant correlations among the domains were observed; the locomotion domain showed the strongest links to the others in network analysis. Conclusions Great declines in IC and disparities between IC domains were found in older inpatients. IC-based primary assessment and classification enabled us to identify the variation of functional abilities among the older inpatients, which is pivotal for designing integrated treatment or care models in clinical practice.

Intrinsic capacity rather than intervention exposure influences reversal to robustness among prefrail community-dwelling older adults: A non-randomized controlled study of a multidomain exercise and nutrition intervention. Front Med (Lausanne) 2022; 9:971497. [PMID: 36341237 PMCID: PMC9634412 DOI: 10.3389/fmed.2022.971497] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Accepted: 10/06/2022] [Indexed: 11/12/2023] Open
Abstract
BACKGROUND The differential risk profiles associated with prefrailty may be attributable to underlying intrinsic capacity (IC). OBJECTIVES We examine (i) effect of a multi-domain physical exercise and nutrition intervention on pre-frailty reversal in community-dwelling older adults at 1-year, and (ii) whether IC contributes to pre-frailty reversal. METHODS Prefrail participants in this non-randomized study were invited to attend a 4-month exercise and nutritional intervention following a frailty screen in the community. Prefrailty was operationalized as (i) FRAIL score 1-2 or (ii) 0 positive response on FRAIL but with weak grip strength or slow gait speed based on the Asian Working Group for Sarcopenia cut-offs. Participants who fulfilled operational criteria for prefrailty but declined enrolment in the intervention programme served as the control group. All participants completed baseline IC assessment: locomotion (Short Physical Performance Battery, 6-minute walk test), vitality (nutritional status, muscle mass), sensory (self-reported hearing and vision), cognition (self-reported memory, age- and education adjusted cognitive performance), psychological (Geriatric Depression Scale-15, self-reported anxiety/ depression). Reversal of prefrailty was defined as achieving a FRAIL score of 0, with unimpaired grip strength and gait speed at 1-year follow-up. RESULTS Of 81 participants (70.0 ± 6.6 years, 79.0% female), 52 participants (64.2%) were enrolled in the multi-domain intervention, and 29 participants (35.8%) who declined intervention constituted the control group. There was no difference in age, gender and baseline composite IC between groups. Reversal to robustness at 1-year was similar between intervention and control groups (30.8% vs. 44.8% respectively, p = 0.206). Reduced prevalence of depression was observed among participants in the intervention group at 1-year relative to baseline (7.8% vs. 23.1%, p = 0.022). In multiple logistic regression, intervention had no effect on prefrailty reversal, while higher composite IC exhibited reduced likelihood of remaining prefrail at 1-year (OR = 0.67, 95% CI 0.45-1.00, p = 0.049). CONCLUSION Focusing only on the locomotion and vitality domains through a combined exercise and nutritional intervention may not adequately address component domain losses to optimize prefrailty reversal. Future studies should examine whether an IC-guided approach to target identified domain declines may be more effective in preventing frailty progression.

Abstract
Purpose Intrinsic capacity (IC) reflects the overall health status of older adults and has great public health significance. But few studies described the related biomarkers for IC. The aim of this study was to investigate the association between homocysteine (Hcy) and IC in older adults. Participants and Methods This cross-sectional study included 1927 community-dwelling Chinese older adults aged 60–98 years from May 2020 to December 2020. Data were collected through interviews, physical examinations, and laboratory tests. IC involved five domains of cognition, locomotion, sensory, vitality, and psychology evaluated by the Mini-cog scale, 4-m walk test, self-reported visual and hearing conditions, MNA-SF scale, and GDS-4 scale, respectively. The score of each domain dichotomized as 0 (normal) and 1 (impaired) was added together to an IC total score. Low IC was defined as a score of 3–5, and high IC as 0–2. Hcy was measured by a two-reagent enzymatic assay. A restricted cubic spline regression model was used to explore the non-linear relationship between Hcy and low IC. Results Hcy was higher in the low IC group than in the high IC group. Restricted cubic spline analysis revealed a J-shaped nonlinear association between Hcy and low IC. The risk of IC decline was slowly decreased until 8.53 µmol/L of Hcy (OR=0.753, 95% CI=0.520–1.091, P=0.132), and increased with elevations of per 5 µmol/L Hcy afterwards (OR=1.176, 95% CI=1.059–1.327, P=0.005). Among the five domains of IC, Hcy had ORs of 1.116 (1.009–1.247) for cognition impairment, 1.167 (1.055–1.305) for vitality, and 1.160 (1.034–1.303) for psychology per 5 µmol/L increase in Hcy above the change point. Additional sensitivity analysis also demonstrated the nonlinear association between Hcy and low IC. Conclusion Hcy had a J-shaped association with low IC. Higher Hcy (Hcy ≥8.53µmol/L) might provide clinical implications for early identifying the risk of low IC.

Abstract
WHO has defined intrinsic capacity (IC) as the composite of all physical and mental capacities of an individual covering five subdomains: cognition, locomotion, sensory, vitality, and psychological. Despite this well accepted definition, the conceptual and measurement model of IC remains unclear, which hampers a standardized operationalization of the construct. We performed a scoping review to give a comprehensive overview of the extent to which the current literature of IC addresses and assumes the conceptual framework and measurement model of IC as reflective or formative. For inclusion, we considered all types of articles that were published in peer-reviewed journals except for protocol articles. A systematic search of 6 databases from different disciplines led to the inclusion of 31 papers. We found inconsistency and gaps in the descriptions of IC. Most of the papers did not define the measurement model. In the conceptual background and validation articles, we identified descriptions of both reflective and formative measurement models while in empirical studies applying IC measurements the underlying assumptions remained mainly unclear. Defining a measurement model is not merely a theoretical matter but influences the operationalization and validation processes of the construct. This study raised questions about the most fundamental features of the IC construct and discusses whether IC should be considered as an underlying latent trait of all capacities (reflective construct) or an aggregate summary measure of the subdomain capacities (formative construct).

Predictors of Successful Memory Aging in Older Mexican Adults. Behav Neurol 2022; 2022:9045290. [PMID: 35795033 PMCID: PMC9252847 DOI: 10.1155/2022/9045290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Revised: 05/19/2022] [Accepted: 06/07/2022] [Indexed: 11/25/2022] Open
Abstract
Background Research suggests a significant association between increasing age and memory impairments. Nevertheless, for some individuals, memory performance stays within or above the normative values of younger subjects. This is known as successful memory aging and is associated with specific neurophysiological features and psychological and lifestyle-related variables. To date, little is known about the association between successful memory aging and intrinsic capacity (IC) defined as “the composite of all the physical and mental (including psychosocial) capacities that an individual can draw on at any point in time” and resilience. Hence, the aim of this study was to determine if longitudinal associations between IC and successful memory aging and resilience exist and to find differences in cognitive performance between Mexican older adults with successful memory aging, older adults with average memory, and older adults with memory impairment. Methods Longitudinal data from 590 individuals from the third wave (2012) and the Mex-Cog subsample (2016) of the Mexican Health and Aging Study was analysed. Subjects were classified into 3 groups: (1) older adults with successful memory aging (SUMA), (2) older adults with average memory (AVMA), and (3) older adults with memory impairment (IMA). Cognitive domains of orientation, language, attention, constructional praxis, and executive function were evaluated. IC and resilience were measured using items from the MHAS battery. Analysis of variance and multinomial logistic regressions were used to find differences in IC and resilience across the memory aging groups. Results ANOVAs showed significant differences across the three cognitive performance groups in all cognitive domains. Multinomial logistic regression analyses revealed that respondents with higher scores in the psychological and cognitive domains of IC at baseline were more likely to have successful memory aging in the subsequent wave of the study. More resilient subjects in 2012 were not more likely to become a SUMA in 2016. However, this could be a result of the way resilience was measured. Conclusion Our main findings suggest that intrinsic capacity could be used as a predictor of successful memory aging specifically in the psychological and the cognitive domains. More longitudinal studies are needed to further examine these associations.

Implementation of the WHO integrated care for older people (ICOPE) programme in clinical practice: a prospective study. THE LANCET. HEALTHY LONGEVITY 2022; 3:e394-e404. [PMID: 36098317 DOI: 10.1016/s2666-7568(22)00097-6] [Citation(s) in RCA: 28] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 04/04/2022] [Accepted: 04/06/2022] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND The INSPIRE integrated care for older people (ICOPE)-CARE programme is a public health programme implementing the ICOPE health-care pathway in clinical practice. The primary objective of this study was to describe the large-scale implementation and feasibility of the INSPIRE ICOPE-CARE guidelines in clinical practice. The secondary aims were to describe the characteristics of patients who were identified as positive for abnormalities in intrinsic capacity (ie, locomotion, cognition, psychology, vitality, hearing, and vision) during step 1, and to describe the prevalence of these positive screenings. METHODS In this prospective study, we evaluated a real-life population of users of primary care services in the Occitania region (France). Participants who were aged 60 years and older and lived in a community were eligible for inclusion in our study. Individuals aged ≥60 years were screened (step 1) by health-care providers or through self-assessments using digital tools (the ICOPE MONITOR app and the ICOPEBOT conversational robot). Our implementation strategy involved raising awareness among health-care professionals about the WHO ICOPE programme, training professionals in the ICOPE-CARE guidelines, and developing a digital infrastructure (ie, digital tools, a database, and a remote ICOPE monitoring platform). The feasibility of implementing the INSPIRE ICOPE-CARE guidelines was determined by the anticipated inclusion of ≥10 000 participants, and having a follow-up rate of over 50%. FINDINGS Between Jan 1, 2020, and November 18, 2021, 10 903 older people (mean age 76·0, SD 10·5 years; 6627 [60·8%] of whom were women) had a baseline step 1 screening done, and 5185 (70·4%) of 7367 eligible participants had a 6-month follow-up of step 1 screening. 10 285 (94·3%) participants had a positive intrinsic capacity result during screening at baseline. 958 (9·3%) participants were evaluated with step 2 (in-depth assessments). Positive intrinsic capacity was confirmed in 865 (90·3%) participants. Most recommendations in step 3 (care plan) were related to locomotion, vitality, and cognition. INTERPRETATION The high number of participants included in our study, as well as the high rates of follow-up, provides evidence to suggest that the large-scale implementation of ICOPE in clinical practice is feasible. The very high prevalence of positive screening for impaired intrinsic capacity during step 1, as well as the high rates of confirmed deficits in intrinsic capacity during step 2, suggest that the INSPIRE ICOPE-CARE programme is able to target individuals who are at increased risk for functional loss and disability.

Healthy Eating Enhances Intrinsic Capacity, Thus Promoting Functional Ability of Retirement Home Residents in Northern Taiwan. Nutrients 2022; 14:nu14112225. [PMID: 35684024 PMCID: PMC9182502 DOI: 10.3390/nu14112225] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Revised: 05/18/2022] [Accepted: 05/25/2022] [Indexed: 12/13/2022] Open
Abstract
Healthy aging is defined as the process of developing and maintaining functional ability in older age with intrinsic capacity, the composite of all the physical and mental capacities of an individual, being the core. This study was conducted to explore the intervention effects of improved dietary quality on intrinsic capacity. A prospective single-group interventional quasi-experimental study with 59 functional independent older adults from retirement homes were recruited. Texture-modified plant-based dietary supplements were provided. In addition, dietary intake, functional ability, and intrinsic capacity in vitality, locomotion, cognition, and psychological capacity were assessed. Vitality was captured by nutritional status, muscle strength, and cardiorespiratory endurance. Locomotor capacity was assessed based on the performance of physical fitness in backscratch test, chair-sit-and-reach test, chair-stand test, one-foot-standing test, and gaits peed. Psychomotor capacity and cognition were measured by using 15-item Geriatric Depression Scale (GDS-15) and Mini-Mental State Examination (MMSE), respectively. In a 4-month of intervention, after controlling for baseline values and covariates, participants with higher dietary intervention adherence showed a significant improvement over time in vitality captured by cardiorespiratory endurance (Pinteraction = 0.009) and significant improvement in locomotion captured by gait speed (Pclusters = 0.034). A significant decrease in the chair-stand test (Ptime = <0.001) and MMSE (Ptime = 0.022) was observed during the four months of intervention. Enhanced intrinsic capacity further contributed to the improvement of ADL over time (Pinteraction = 0.034). In conclusion, healthy eating enhances intrinsic capacity in vitality and locomotion thus promoting functional ability among older adults.

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.

Intrinsic capacity of older people in the community using WHO Integrated Care for Older People (ICOPE) framework: a cross-sectional study. BMC Geriatr 2022; 22:304. [PMID: 35395736 PMCID: PMC8993034 DOI: 10.1186/s12877-022-02980-1] [Citation(s) in RCA: 20] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Accepted: 03/23/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The World Health Organization (WHO) published the Integrated Care for Older People (ICOPE) framework to guide assessing and promoting intrinsic capacity of older adults. This study, adopting the WHO ICOPE framework, assessed the intrinsic capacity impairment and investigated the relationship among intrinsic capacity, social engagement, and self-care capacity on performing activities of daily living. It also assessed the sensitivity of the initial brief screening and the detailed full assessment. METHODS This is a cross-sectional study conducted in 11 community centers in Hong Kong. Intrinsic capacity was assessed in two steps identical to WHO ICOPE handbook: using WHO ICOPE brief screening tool (step 1) and detailed full assessment (step 2) to assess the intrinsic capacity domains of locomotion, cognition, vitality, psychological well-being, and sensory capacity (hearing and vision). Structural equational modeling analysis was used to examine the relationship among intrinsic capacity, social engagement, and self-care capacity, and the mediating role of intrinsic capacity in the relationships. RESULTS A total of 304 older adults with a mean age 76.73 (SD = 7.25) years participated in WHO ICOPE Step 1 brief screening, and 221 participants (72.7%) showed intrinsic capacity impairment. After completing Step 2 full assessment, 202 participants (66.4%) had one or more impaired intrinsic capacity domains. The overall sensitivity and specificity of the screening tool were 95% and 57.6% respectively, whereas the sensitivity of each domain ranged from 74.7% to 100%. The percentage of impairment in locomotion (117, 39.8%), cognition (75, 25.5%), psychological well-being (34, 11.6%), vision (75, 24.7%), hearing capacity (82, 27.9%), and vitality (8, 2.7%). People in younger old age (β = -0.29, p < 0.001), with more education (β = 0.26, p < 0.001), and absence of hypertension (β = -0.11, p < 0.05) were more likely to have better intrinsic capacity. Intrinsic capacity was positively associated with self-care capacity in performing activities of daily living (β = 0.21, p < 0.001) and social engagement (β = 0.31, p < 0.001). CONCLUSIONS The ICOPE screening tool is a sensitive instrument to detect intrinsic capacity impairment among community-dwelling older adults and it does not demand substantial workforce; its use is worthy to be supported. The intrinsic capacity impairment in community-dwelling older adults are prevalent, in particular, in locomotor and cognitive capacity. Actions should be taken to slow or prevent the impairment, support self-care and social engagement in old age.

Abstract
OBJECTIVES To examine whether intrinsic capacity (IC) could predict frailty, whether declines in specific domains of IC could lead to frailty, and whether different combinations of domains could represent different risks of developing frailty. SETTING Community. PARTICIPANTS Chinese people aged 65 years and older. MEASUREMENTS Using data from a prospective cohort study, we derived a summary score for IC and scores for the five domains (cognitive, locomotor, vitality, sensory, psychological) for each participant at baseline. Frailty was assessed according to the Fried's frailty phenotype at baseline, 2- and 4-year follow-ups. Participants were classified as frail if they had ≥3 of the following criteria: weight loss, self-rated exhaustion, weakness, slow walking speed, and low physical activity. RESULTS Four thousand participants were interviewed at baseline. Overall mean age was 72.5 years; 50% were women. Between baseline and the 2-year follow-up, 5.7% of non-frail participants developed frailty; between 2- and 4-year follow-ups, 5.7% of non-frail participants developed frailty. The average annual incidence rate of frailty was 2.9%. Higher scores on IC at baseline were associated with a lower risk of incident frailty at both follow-ups (year 2, odds ratio (OR)=0.64, 95% confidence interval (CI)=0.59-0.71); year 4, OR=0.64, 95%CI=0.58-0.71) after adjustment for age, sex, educational level, and chronic diseases. Across the five domains, vitality was the strongest predictor of incident frailty at each follow-up (year 2, OR=0.33, 95%CI=0.24-0.45; year 4, OR=0.33, 95%CI=0.23-0.46). Compared to other combinations of any two domains, having 'high' scores on both vitality and locomotor domains was associated with the lowest risk of incident frailty (year 2, OR=0.11, 95%CI=0.06-0.22, area under the curve (AUC)=0.770; year 4, OR=0.18, 95%CI=0.10-0.32, AUC=0.782). CONCLUSION This study provides evidence that IC was independently associated with incident frailty. It also finds that vitality was the domain most strongly associated with incident frailty. Finally, it suggests that optimizing multiple domains of IC, particularly vitality and locomotor, may prevent frailty.
