Association between Physical Function, Mental Function and Frailty in Community-Dwelling Older Adults: A Cross-Sectional Study.

Background: This study examines the relationship between physical and mental function and frailty, independently and in conjunction with polypharmacy, among older adults. Methods: This cross-sectional study consisted of 368 participants aged ≥60 years. The participants were categorized into either robust or frail groups using Fried's frailty phenotype. Physical functions were assessed using grip strength, gait speed, Timed Up and Go (TUG), the Five Chair Sit to Stand Test (FCSST) and the Six-Minute Walk Test (SMWT). Mental functions were assessed using cognitive function and depression. Cognitive function was measured using Mini-Mental State Examination (MMSE). Depression was assessed with the Korean version of the Short Geriatric Depression Scale (SGDS). Results: The mean age of study population was 75.4 years. In this population, we identified 78.8% (n = 290) robust participants and 21.2% (n = 78) frail participants. The study examined frailty status (frail vs. non-frail) and frailty with and without polypharmacy using multivariate logistic regressions, adjusting for age and sex. In the logistic regression model estimating the risk of frailty, after adjustments for age, sex, BMI, and number of medications, individuals with low SMWT showed a significantly increased risk of frailty, with an odds ratio (OR) of 8.66 and a 95% confidence interval (CI) of 4.55-16.48. Additionally, global cognitive function was associated with a 1.97-fold increase in frailty risk (95% CI: 1.02-3.67). Moreover, in models adjusted for age, sex, and BMI to assess frailty risk linked to polypharmacy, the TUG, SMWT, and SGDS all showed increased risks, with ORs of 3.65 (95% CI: 1.07-12.47), 5.06 (95% CI: 1.40-18.32), and 5.71 (95% CI: 1.79-18.18), respectively. Conclusions: Physical function (SMWT, FCSST, TUG) and mental function (depression, cognition) were associated with frailty. By comprehensively examining these factors, we will gain valuable insights into frailty and enable more precise strategies for intervention and prevention.

Decreased mitochondrial respiration associates with frailty in community-dwelling older adults.

Aging population has led to an increased prevalence of chronic and degenerative pathologies. A manifestation of unhealthy aging is frailty, a geriatric syndrome that implies a non-specific state of greater vulnerability. Currently, methods for frailty diagnosis are based exclusively on clinical observation. The aim of this study is to determine whether the bioenergetic capacity defined as mitochondrial oxygen consumption rate (OCR) of peripheral circulation mononuclear cells (PBMC) associates with the frailty phenotype in older adults and with their nutritional status. This is a cross-sectional analytic study of 58 participants 70years and older, 18 frail and 40 non-frail adults, from the ALEXANDROS cohort study, previously described. Participants were characterized through sociodemographic and anthropometric assessments. Frail individuals displayed a higher frequency of osteoporosis and depression. The mean age of the participants was 80.2 ± 5.2years, similar in both groups of men and women. Regarding the nutritional status defined as the body mass index, most non-frail individuals were normal or overweight, while frail participants were mostly overweight or obese. We observed that OCR was significantly decreased in frail men (p < 0.01). Age was also associated with significant differences in oxygen consumption in frail patients, with lower oxygen consumption being observed in those over 80years of age. Therefore, the use of PBMC can result in an accessible fingerprint that may identify initial stages of frailty in a minimally invasive way.

The roles of health literacy and social support in the association between smartphone ownership and frailty in older adults: a moderated mediation model

BackgroundUnderstanding the role of smartphones to promote the health status of older adults is important in the digital society. Little is known about the effects of having smartphones on physical frailty despite its positive effect on the well-being of older adults. This study aimed to explore the association between smartphone ownership and frailty in community-dwelling older adults and its underlying mechanism.MethodsWe used data from the Korean Frailty and Aging Cohort Study and analyzed 2,469 older adults aged 72–86 years. Frailty, health literacy, and social support were assessed by Fried’s frailty phenotype, the Behavioral Risk Factor Surveillance System health literacy module, and the Enhancing Recovery in Coronary Heart Disease (ENRICHD) Social Support Instrument, respectively. The mediation model and moderated mediation model were estimated, where the mediator was health literacy and the moderator was social support, to explore the relationship between smartphone ownership and frailty.ResultsOf our study participants, 58.9% owned smartphones, and 10.9% were classified as frail. Smartphone ownership was negatively associated with frailty (β = −0.623, p < 0.001). Health literacy mediated the relationship between smartphone ownership and frailty (β = −0.154, boot confidence interval [CI] = − 0.222, − 0.096), and social support moderated the mediation effect (β = −0.010, Boot CI = − 0.016, − 0.004).ConclusionsOwning smartphones among older adults could reduce the risk of frailty. Promoting health literacy and social support among older adults with smartphones would be effective to prevent frailty.

Intrinsic capacity assessment using World Health Organization Integrated Care for Older People Step 1, and the association with frailty in community dwelling older adults.

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. 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. 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). 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.

Preventive Home Visits Among Frail Community-Dwelling Older Adults. The Added Value of Follow-Up Telephone Calls

ABSTRACT People in need of care and support do not always find appropriate services. This paper aims to explore the content and added value of monthly follow-up telephone calls after preventive home visits. We used both monitoring data and qualitative semi-structured interviews (with older adults, formal and informal caregivers). Results indicate that a majority of older adults (N = 95) received a regular follow-up of four telephone calls. Social connection and involvement were mentioned by all three groups as positive aspects of the program. Although time-consuming, this paper draws attention to the added value of follow-up telephone calls after preventive home visits.

Association of the Combination of Moderate-to-Vigorous Physical Activity and Sleep Quality with Physical Frailty.

The association of the individual and combined effects of moderate-to-vigorous physical activity (MVPA) and sleep quality with physical frailty in community-dwelling older adults is still unknown. A cross-sectional study was conducted with a sample of older adults who had not required nursing care or support services. Physical frailty was assessed using Liu's definition based on Fried's concept. MVPA was measured by a triaxial accelerometer, and individuals who met either moderate physical activity (MPA) for ≥300 min/week, vigorous physical activity (VPA) for ≥150 min/week, or both were defined as "MVA+". "SLP+" was defined as a Pittsburgh Sleep Quality Index score of <5.5 points. A total of 811 participants were included in the final analysis. After adjusting for the multivariable confounding factors, the odds ratios (ORs) and 95% confidence intervals (CIs) for physical pre-frailty and frailty in the MVA-SLP+ (OR, 2.56; 95%CI, 1.80-3.62) and the MVA-SLP- group (OR, 3.97; 95%CI, 2.33-6.74) were significantly higher compared with the MVA+SLP+ group. Community-dwelling older adults who did not meet the MVPA criteria, regardless of sleep quality, had a higher prevalence of physical frailty.

Psychosocial stressors associated with frailty in community-dwelling older adults in the United States.

Frailty is multifactorial; however, psychosocial stressors contributing to frailty are poorly understood. This study aimed to examine whether gender, race/ ethnicity, and education are associated with differential exposure to psychosocial stressors, determine psychosocial stressors contributing to frailty, and explore the mediating psychosocial stressors pathway. This cross-sectional study involved 7679 community-dwelling older adults (≥65) from the Health and Retirement Study (2006 and 2008 waves). Psychosocial stressors such as loneliness, low subjective social status, financial strain, poor neighborhood cohesion, everyday discrimination, and traumatic life events were measured. Frailty was defined by the Fried phenotype measure. Multivariable logistic regressions were used to examine the association of gender, race/ethnicity, and education with psychosocial stressors, psychosocial stressors associated with frailty, and the mediating psychosocial stressors pathway. Females experienced greater financial strain but lower discrimination (both p < 0.05). Older adults who identified as Hispanic, Black, and racially or ethnically minoritized experienced low subjective social status, high financial strain, low neighborhood cohesion, and high discrimination than their White counterparts (all p < 0.05). Those with lower education experienced high loneliness, low subjective social status, high financial strain, low neighborhood cohesion but lower traumatic life events (all p < 0.05). Psychosocial stressors: High loneliness, low subjective social status, high financial strain, and low neighborhood cohesion (all p < 0.05) independently increased the odds of frailty. The mediating pathway of psychosocial stressors was not significant. CONCLUSION: Disparities exist in exposure to psychosocial stressors associated with frailty. Multilevel interventions are needed to reduce the influence of psychosocial stressors on frailty.

Evaluation of Sex and Age Factors Contributing to the Diagnosis of Oral Frailty in Community-Dwelling Older Adults

Evaluation of Sex and Age Factors Contributing to the Diagnosis of Oral Frailty in Community-Dwelling Older Adults

Impact of the anti-inflammatory diet on serum high-sensitivity C-Reactive protein and new-onset frailty in community-dwelling older adults: A 7-year follow-up of the Kashiwa cohort study.

Chronic inflammation is a pathophysiological cause of age-related diseases, including frailty. Although diet is a determinant of inflammation, few prospective studies have investigated its role in frailty onset. This study used the dietary inflammatory index to investigate whether a proinflammatory diet affects the incidence of frailty in a 7-year follow-up of older Japanese adults. We enrolled community-dwelling older adults without frailty from the 2014 Kashiwa cohort study. Energy-adjusted dietary inflammatory index (E-DII) scores were calculated using a brief self-administered diet history questionnaire. Serum high-sensitivity C-reactive protein (hsCRP) levels were measured by immunoassays. Frailty was defined as meeting three of Fried's five phenotypic criteria. Cox regression was used to analyze associations between E-DII scores and new-onset frailty after adjusting for relevant confounders. Overall, 95 (11.7%) of 811 participants (73.7 ± 4.8 years, women 47.3%) developed new-onset frailty during the 7-year follow-up. The baseline E-DII scores significantly correlated with log-hsCRP levels, even after adjustment (β = 0.075, P = 0.035). The highest tertile of E-DII scores (proinflammatory diet) showed a 2.03 times (95% confidence interval, 1.22-3.36) higher risk of new-onset frailty than that associated with the lowest tertile (P = 0.006). When E-DII was calculated on the basis of anti-inflammatory food parameters only, the highest tertile showed a 2.32 times (95% confidence interval, 1.36-3.95) higher risk than that associated with the lowest tertile (P = 0.002). E-DII scores significantly correlated with serum hsCRP levels. High E-DII scores caused by low intake of anti-inflammatory foods are associated with frailty incidence. For community-dwelling older adults, dietary interventions that lower E-DII scores (e.g., encouraging dietary fiber intake) may help prevent frailty. Geriatr Gerontol Int 2024; 24: 189-195.

DEVELOP AND EXTERNALLY VALIDATE A RISK PREDICTION MODEL FOR SCREENING COGNITIVE FRAILTY IN OLDER ADULTS

Abstract Cognitive frailty, the combination of physical frailty and mild cognitive impairment, is a growing public health concern in aging populations. We aimed to develop and validate a risk prediction model for screening cognitive frailty in community-dwelling older adults without probable dementia (aged ≥ 65 years). We used Year 2011 data from National Health and Aging Trends Study (NHATS), with participants randomly divided into the training set (N=4,222) and internal validation set (N=2,111). We used Year 2015 data of NHATS as the external validation set (N=3,380). Cognitive frailty was assessed with the Fried phenotypic criteria and cognitive performance in three domains (memory, orientation and executive function). Independent risk factors were screened by multivariate logistic regression analysis. Model performance was assessed by discrimination (area under the curve [AUC]) and calibration (Hosmer-Lemeshow test). The final model included 13 key predictors (age, gender, education, smoke, walking for exercise, vigorous activity, self-rated health, depressive symptoms, balance impairments, arthritis, hospitalization, activities of daily living, and instrumental activities of daily living score). The model showed good discrimination with an AUC of 0.92 (95% CI: 0.90-0.93) for the training set, 0.92 (95% CI: 0.89-0.95) for the internal validation set, and 0.88 (95% CI: 0.85-0.91) for the external validation set. The Hosmer-Lemeshow test yielded P values of 0.10, 0.92, and 0.85 for the three sets, respectively, suggesting good calibration. Our risk prediction model has the potential to screen older adults at risk for cognitive frailty, enabling early interventions to prevent or delay cognitive decline and physical disability.

BRIDGING RESEARCH TO PRACTICE: PRO-HOME EMPOWERS CARE PARTNERS TO PROMOTE EXERCISE IN HOME CARE

Abstract Regular physical activity (PA) benefits people of all ages. Mounting scientific evidence shows PA’s health benefits in older persons with chronic conditions. However, there remains a large research-to-practice gap in PA, especially in long-term services and supports (LTSS). Older adults who need help with basic daily activities, such as walking or standing, continue to face barriers at multiple levels of LTSS to become and remain physically active. This symposium will address the much-debated research-to-practice gaps, focusing on frail community-dwelling older adults in the context of a NIA-funded clinical trial. “Promoting Seniors’ Health with Home Care Aides (Pro-Home)” tests the effectiveness of a gentle, low-intensity PA program delivered by home care aides (HCAs) for community-dwelling older adults with nursing-home eligible care needs in real-world home care settings. Pro-Home is innovative because it empowers direct care workers (HCAs) with an easy-to-learn toolkit to deliver the program and keep their older clients motivated. The symposium starts with an overview of Pro-Home (Muramatsu), barriers and facilitators of Pro-Home at multiple levels of the LTSS system (Cruz Madrid), followed by Pro-Home’s critical elements: of research and practice: client-HCA dyad relationships and partnerships with stakeholders (Hu), in-home assessment of motor function in frail older adults (Yin), and inter-professional co-learning (Skowronski). The symposium concludes with a dialogue with the audience to identify actionable policy and practice strategies for building research-to-practice and practice-to-research bridges to build health promotion into LTSS to promote the well-being of older adults with disabilities and their care partners.

Validation of the Korean Academy of Geriatric Dentistry screening questionnaire and oral frailty diagnostic criteria in community-dwelling older adults.

This study aimed to establish the validity-specifically, the sensitivity and specificity-of the screening questionnaire and diagnostic criteria for oral frailty proposed by the Korean Academy of Geriatric Dentistry (KAGD) among community-dwelling older adults. This study enrolled 100 participants. Among various definitions of oral frailty, this study used the criteria proposed by Tanaka as the reference test. The screening questionnaire consisted of 11 items for screening physical frailty, chewing ability, swallowing difficulties, oral dryness, and tongue and lip motor function. Each question had a different scoring weight, and if the total score was 1 or higher, an oral frailty diagnostic examination proposed by the KAGD would be recommended. The diagnostic test was the oral frailty diagnostic criteria proposed by the KAGD including 6 measures: chewing ability, occlusal force, tongue pressure, oral dryness, swallowing difficulty, and oral hygiene. If a participant exhibited 2 or more positive measures, this participant was classified as "oral frail." The screening questionnaire was analyzed using a cut-off value of 1 or higher, while the diagnostic criteria utilized a cut-off of 2 or more positive measures. Sensitivity and specificity were calculated. The screening questionnaire showed significant power for screening oral frailty (area under the receiver operating characteristic curve, 0.783; sensitivity, 87.8%; specificity, 52.5%). The diagnostic accuracy of the newly proposed diagnostic criteria was acceptable (sensitivity, 95.1%; specificity, 42.4%). The newly proposed screening questionnaire and diagnostic criteria in Korea appear to be a useful tool to identify oral frailty in community-dwelling older adults.

Sit-to-Stand Video Analysis-Based App for Diagnosing Sarcopenia and Its Relationship With Health-Related Risk Factors and Frailty in Community-Dwelling Older Adults: Diagnostic Accuracy Study.

Probable sarcopenia is determined by a reduction in muscle strength assessed with the handgrip strength test or 5 times sit-to-stand test, and it is confirmed with a reduction in muscle quantity determined by dual-energy X-ray absorptiometry or bioelectrical impedance analysis. However, these parameters are not implemented in clinical practice mainly due to a lack of equipment and time constraints. Nowadays, the technical innovations incorporated in most smartphone devices, such as high-speed video cameras, provide the opportunity to develop specific smartphone apps for measuring kinematic parameters related with sarcopenia during a simple sit-to-stand transition. We aimed to create and validate a sit-to-stand video analysis-based app for diagnosing sarcopenia in community-dwelling older adults and to analyze its construct validity with health-related risk factors and frailty. A total of 686 community-dwelling older adults (median age: 72 years; 59.2% [406/686] female) were recruited from elderly social centers. The index test was a sit-to-stand video analysis-based app using muscle power and calf circumference as proxies of muscle strength and muscle quantity, respectively. The reference standard was obtained by different combinations of muscle strength (handgrip strength or 5 times sit-to-stand test result) and muscle quantity (appendicular skeletal mass or skeletal muscle index) as recommended by the European Working Group on Sarcopenia in Older People-2 (EWGSOP2). Sensitivity, specificity, positive and negative predictive values, and area under the curve (AUC) of the receiver operating characteristic curve were calculated to determine the diagnostic accuracy of the app. Construct validity was evaluated using logistic regression to identify the risks associated with health-related outcomes and frailty (Fried phenotype) among those individuals who were classified as having sarcopenia by the index test. Sarcopenia prevalence varied from 2% to 11% according to the different combinations proposed by the EWGSOP2 guideline. Sensitivity, specificity, and AUC were 70%-83.3%, 77%-94.9%, and 80.5%-87.1%, respectively, depending on the diagnostic criteria used. Likewise, positive and negative predictive values were 10.6%-43.6% and 92.2%-99.4%, respectively. These results proved that the app was reliable to rule out the disease. Moreover, those individuals who were diagnosed with sarcopenia according to the index test showed more odds of having health-related adverse outcomes and frailty compared to their respective counterparts, regardless of the definition proposed by the EWGSOP2. The app showed good diagnostic performance for detecting sarcopenia in well-functioning Spanish community-dwelling older adults. Individuals with sarcopenia diagnosed by the app showed more odds of having health-related risk factors and frailty compared to their respective counterparts. These results highlight the potential use of this app in clinical settings. ClinicalTrials.gov NCT05148351; https://clinicaltrials.gov/study/NCT05148351. RR2-10.3390/s22166010.

Effectiveness of subjective support-focused cognitive behavioral therapy on depressive symptoms among (pre)frail community-dwelling older adults: A randomized controlled trial

BackgroundSubjective support could ameliorate the adverse effect of (pre)frailty on depressive symptoms. However, there is scarce evidence regarding subjective support-focused intervention in preventing depression among (pre)frail community-dwelling older adults. This study aims to explore the effectiveness of subjective support-focused cognitive behavioral therapy (SS-CBT) in preventing depression among this group of population. MethodsA total of 100 community-dwelling (pre)frail older adults were recruited from six communities in a Chinese city and were randomized to an 8-week SS-CBT group or a wait-list control group. Depressive symptoms and subjective support were assessed at baseline (T0), and at 8 week (T1), 12 week (T2), 16 week (T3) after randomization. Generalized estimating equation was used to examine the effectiveness of SS-CBT on depressive symptoms and subjective support. Hierarchical linear regression models and Bootstrapping method were used to examine whether subjective support mediated the effectiveness of SS-CBT on depressive symptoms. ResultsParticipants in SS-CBT group reported significant reduction in depressive symptoms (Wald χ2 = 20.800, p < 0.001) and improvement in subjective support (Wald χ2 = 92.855, p < 0.001) compared to those in wait-list control group. Changes in subjective support mediated the effectiveness of SS-CBT on changes in depressive symptoms. LimitationsRestricted regions to recruit participants, inclusion of the most motivated participants, lack of diagnosis of depression, potential experimenter bias and contamination, short follow-up period, and lack of an active control group. ConclusionsThe findings support the benefits of SS-CBT in preventing depression among (pre)frail community-dwelling older adults, and provide insight into possible mechanisms.

Abstract 13194: Association Between Left Atrial Function and Frailty: The Atherosclerosis Risk in Communities (ARIC) Study

Background: Frailty is highly common in people with cardiovascular disease. Worse left atrial (LA) function is an independent risk factor for cardiovascular disease. However, whether worse LA function is independently associated with frailty is unclear. Aim: To evaluate the association of LA function with incident frailty in community-dwelling older adults. Methods: We included 3,292 older adults from the Atherosclerosis Risk in Communities (ARIC) study who were non-frail at baseline (visit 5, 2011-2013) and had LA function (reservoir strain, conduit strain, and contractile strain) measured from two-dimensional speckle-tracking echocardiography. The validated Fried frailty phenotype, which includes measurements of weight loss, slowness, exhaustion, weakness, and low physical activity, was used to define frailty (≥3 of the 5 components). Incident frailty was assessed between 2016 and 2019 during 2 follow-up visits; all the included participants attended at least 1 of the 2 visits. LA function was assessed continuously (per 1-SD decrement) and categorically in quintiles. Multivariable logistic regression was used for analysis. Results: The median (IQR) age was 74 (71-77) years (58% female) and 214 (7%) participants developed frailty during a median (IQR) follow-up of 6.3 (5.6-6.8) years. After adjusting for potential confounders, each 1-SD decrement in LA reservoir strain and LA contractile strain was associated with 35% (95% CI: 11-65%) and 22% (95% CI: 2-45%), respectively, greater odds of developing frailty ( Table 1 ). Compared to the highest quintile, participants in the lowest quintile of LA reservoir strain had 2.3-fold greater odds of developing frailty. Conclusions: Worse LA function is associated with higher incidence of frailty. Future studies are needed to investigate the mechanism underlying this association.

Validity of a simple self-reported questionnaire “Eleven-Check” for screening of frailty in Japanese community-dwelling older adults: Kashiwa cohort study

PurposeFrailty was indicated to be closely related to older adults’ lifestyles, especially in nutrition-related factors (such as balanced diet and oral functions), physical factors, and social factors in our previous study. Here, we developed an "Eleven-Check" (EC) questionnaire containing the aforementioned three factors. This study tested whether the EC questionnaire can estimate frailty in community-dwelling older adults. Materials and MethodsThe study sample comprised 1,523 independent older adults. The primary outcome of frailty was assessed using the Cardiovascular Health Study index. The secondary outcome of sarcopenia was assessed by the criteria of the Asian Working Group for Sarcopenia 2019. The EC questionnaire comprised 11 dichotomous factors related to nutrition-related (diet and oral functions), physical, and social factors. ResultsFrailty prevalence was 8.5 % (76.1 ± 5.8y, 45.1 % women). The accuracy of the EC questionnaire for frailty was optimal when the total scores of 4/5 were used as the threshold. Compared to the low-risk group (<5), the high-risk group (≥5) had a significant association between frailty with an adjusted odds ratio (aOR) of 4.68 (95 %CI, 3.10–7.05). Moreover, the high-risk group also had a significant association with sarcopenia, with an aOR of 1.82 (1.27–2.61). ConclusionsFor community-dwelling older adults, the EC questionnaire was able to simply screen frailty and sarcopenia status. Further, it might raise older adults’ self-awareness from a multifaceted perspective in their daily life to prevent steady decline and frailty sustainably in a community setting.

Cognitive frailty in older adults with diabetes: prevalence and risk factors.

In older adults living with diabetes, there is a higher prevalence of frailty and a greater risk of cognitive impairment. Cognitive frailty is defined by the presence of both and is associated with an increased risk of mortality. A systematic review was undertaken to estimate the prevalence of cognitive frailty in community-dwelling older adults living with diabetes and associated risk factors. This commentary critically appraises the review and explores the implications of the findings for community practice.

Prevalence and associated factors of cognitive frailty in community-dwelling older adults: Results from the Korean longitudinal study of aging.

Cognitive frailty, a condition characterized by physical frailty with cognitive impairment, is emerging as a determinant of adverse health outcomes in older adults. However, its prevalence and correlation with associated factors are unknown in the aging population of Korea. To estimate the prevalence of cognitive frailty and identify factors associated with it among older Korean adults. A secondary analysis was performed using the Korean Longitudinal Study of Aging seventh survey dataset collected in 2018. Multinomial logistic regression analyses were conducted to examine the association between cognitive frailty and demographic, psychosocial, oral health and physical function factors. Individuals aged ≥65 years and without dementia were included (N = 1024). Participants were classified into four groups based on the presence or absence of physical frailty and mild cognitive impairment. This article is executed in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. The prevalence of cognitive frailty in the study sample was 11.2%. The results of multinomial logistic regression showed that advanced age, being female, lower education levels, heart disease, arthritis or rheumatoid arthritis, underweight, depression, non-social activity, poor oral health and functional limitation were significantly associated with cognitive frailty. Cognitive frailty is prevalent among community-dwelling older adults in Korea. The findings provide primary care providers with insights about effective strategies for identifying at-risk individuals and will guide the development of population-level interventions to prevent or delay the onset of physical frailty and cognitive impairment in older adults. The findings provide practical information to healthcare providers for identifying cognitive frailty in older adults. The risk factors of cognitive frailty, such as psychosocial, oral health, and physical function factors, should be thoroughly monitored for older adults. Health personnel working in primary care have a critical role in identifying risk and beneficial factors and promoting preventative strategies that enhance health outcomes.

Implementation and Core Components of a Multimodal Program including Exercise and Nutrition in Prevention and Treatment of Frailty in Community-Dwelling Older Adults: A Narrative Review.

Increasing disability-free life expectancy is a crucial issue to optimize active ageing and to reduce the burden of evitable medical costs. One of the main challenges is to develop pragmatic and personalized prevention strategies in order to prevent frailty, counteract adverse outcomes such as falls and mobility disability, and to improve quality of life. Strong evidence reports the effectiveness of exercise interventions to improve various physical parameters and muscle function that are cornerstones of frailty. Other findings also suggest that the interactions between nutrition and physical exercise with or without health behavior promotion prevent the development of frailty. Multimodal programs, including structured exercise, adequate dietary intervention and health behavior promotion, appear increasingly consensual. However, in order for implementation in real-life settings, some pitfalls need to be addressed. In this perspective, structuring and tailoring feasible, acceptable and sustainable interventions to optimize exercise training responses are essential conditions to warrant short, medium and long-term individual benefits. The different components of exercise programs appear to be fairly consensual and effective. However, specific composition of the programs proposed (frequency, intensity, type, time, volume and progressiveness) have to be tailored to individual characteristics and objectives in order to improve exercise responses. The intervention approaches, behavioral strategies and indications for these programs also need to be refined and framed. The main objective of this work is to guide the actions of healthcare professionals and enable them to widely and effectively implement multimodal programs including exercise, nutrition and behavioral strategies in real-life settings.
