Development of a Fried Frailty Phenotype Questionnaire for Use in Screening Community-Dwelling Older Adults

Development of a Screening Tool for Oral Frailty in Community-Dwelling Older Adults: A Cross-Sectional Study

OBJECTIVES

To develop a Screening for Oral Frailty Tool (SOFT) and evaluate its reliability and validity among Chinese community-dwelling older adults.

DESIGN

Cross-sectional analysis.

SETTING AND PARTICIPANTS

The study was conducted as part of an ongoing community-based prospective study in Shanghai. A total of 307 older adults, aged between 60 and 96 years, participated in the study.

METHODS

This study was conducted in 3 stages: item development, scale development, and scale evaluation. This study was based on a visual model depicting the deterioration of oral function, and a draft scale was generated based on a literature review, existing scales, expert consultations, and cognitive interviews. Between December 2023 and February 2024, the validity and reliability of the SOFT were evaluated using a questionnaire administered to 307 community-dwelling older adults. Data including demographics, frailty, and sarcopenia were collected.

RESULTS

The oral frailty scale comprises 6 items, including number of teeth, difficulty in swallowing, difficulty in chewing, difficulty in articulatory oral motor, dry mouth, and oral pain, and is assessed using a yes or no question. The correlations ranged from 0.40 to 0.66 when correlating each item with the total score of the scale. Using frailty and sarcopenia as criteria, the area under the curve for the SOFT was 0.71. The optimal cutoff for the SOFT was 2, using frailty as a criterion, with a higher Youden index and a high negative predictive value (94.9%), but a low positive predictive value (19.3%). The SOFT showed low internal consistency (Kuder-Richardson formula 20 coefficients 0.50) and good test-retest reliability (intraclass correlation coefficients 0.86).

CONCLUSIONS AND IMPLICATIONS

The SOFT does not require specialized equipment and is not affected by cultural differences. It can be used for oral frailty screening in Chinese community-dwelling older adults and is simple and rapid.

Psychometric Properties of the FRAIL Scale for Frailty Screening: A Scoping Review

OBJECTIVES

The aim of this study was to identify and map the available psychometric evidence of the FRAIL scale to screen frailty among older adults.

DESIGN

Scoping review of published articles on 9 databases (PubMed, Scopus, Web of Science, CINAHL, Cochrane, Embase, PsycINFO, VHL Regional Portal, and Epistemonikos) and 8 gray literature sources.

SETTING AND PARTICIPANTS

Studies in adults or older adults, in both inpatient and outpatient settings (without context restrictions).

METHODS

Cross-cultural adaptations, validity and reliability evidence studies, whose main objective was to develop and/or validate and/or culturally adapt the FRAIL Scale to assess frailty in adults or older adults, published since 2007 were included in this scoping review. The databases were searched between February and March 2023.The JBI methodology for scoping reviews was used to guide the process. The protocol of this study was registered on the Open Science Framework platform.

RESULTS

Of the 1031 records found during the search, 40 articles that met the established criteria for analysis were included. Nearly 1 in 10 countries worldwide (11.9%) have psychometric evidence regarding this scale. Ten studies were identified with the goal of cross-cultural adaptation and/or validation in a different cultural context for the first time. Twenty-one of 40 studies used Morley 2012 operationalization of FRAIL Scale criteria. Thirty-nine studies provided evidence of associations with other variables. The rest of the evidence for content, internal structure, response processes, and reliability was only evaluated in cross-cultural adaptation studies, with limitations.

CONCLUSIONS AND IMPLICATIONS

In conclusion, there is some evidence of validity for FRAIL Scale; nevertheless, studies are needed to adapt the scale to new cultures, using rigorous Cross-Cultural Adaptation processes, and to provide new evidence of validity and reliability, to strengthen and consolidate the body of knowledge for its application to various patient groups and context.

Role of Individual Social Capital in the Association of Physical Frailty With Functional Ability Among Older Adults

OBJECTIVES

Rich social capital is regarded as an individual's social asset, which may contribute to the maintenance of functional ability, even in a state of frailty. This study examined the moderating role of individual social capital in the association between physical frailty and functional ability among older adults.

DESIGN

A cross-sectional study.

SETTING AND PARTICIPANTS

In total, 522 community-dwelling older adults aged ≥60 years were recruited from among visitors to public facilities, including community cultural centers and gymnasiums in Aichi, Japan.

METHODS

Functional ability was assessed using the 5-item subscale of the Tokyo Metropolitan Institute of Gerontology Index of Competence that assesses instrumental self-maintenance, including transportation, finance management, and shopping. Physical frailty was defined by the Fried Frailty Phenotype Questionnaire, including 5 items of fatigue, resistance, ambulation, inactivity, and weight loss, and the participants were classified into 3 groups: non-frailty, pre-frailty, and frailty. Individual social capital was assessed for 2 dimensions: the cognitive dimension (perceptions of community social cohesion) and the structural dimension (informal socializing and social participation).

RESULTS

The participants' mean age (SD) was 74.1 (6.5) years and 78.0% were women. Among the participants, non-frailty was 46.6%, pre-frailty was 47.0%, and frailty was 6.5%. Multivariable linear regression analysis revealed that physical frailty was associated with lower levels of functional ability compared with non-frailty [pre-frailty: β (95% CI) = -0.07 (-0.22 to 0.08), P = .374; frailty: β = -0.67 (-0.99 to -0.35), P < .001]. However, individual structural social capital showed a negative interaction with physical frailty against low functional ability, indicating a moderating association (P = .027).

CONCLUSIONS AND IMPLICATIONS

High levels of individual structural social capital mitigated the adverse association between physical frailty and functional ability. Fostering rich social capital may preserve the functional ability of frail older adults, helping their independent lives in the community.

A Modified Frailty Phenotype Used for Identifying Frailty in Health Care Practice: Validation Among Chinese Older Adults

OBJECTIVES

The study aimed to evaluate a simplified and practical frailty detection tool derived from the Fried frailty phenotype (FFP). This tool was developed to facilitate the identification of frail individuals in constrained settings, addressing the challenges posed by uncertain cutoffs of FFP indicators in prompt frailty assessment.

DESIGN

A longitudinal study and a cross-sectional study.

SETTINGS AND PARTICIPANTS

A total of 1978 older adults aged 67.4 ± 6.16 years from the China Health and Retirement Longitudinal Study (CHARLS), and 972 older adults aged 72.8 ± 6.75 years from a pilot cross-sectional study conducted in Shanghai communities.

METHODS

Frailty was assessed according to the FFP criterion. A Chinese modified frailty phenotype (CMFP) was developed, incorporating specific cutoffs for grip strength and an alternative test for walk speed. The internal consistency reliability, the criterion, and predictive validity of the CMFP were evaluated.

RESULTS

The 5-time chair stand test (5t-CST) was significantly associated with the 2.5-m walk test (r = 0.373 in the CHARLS and 0.423 in the pilot study). Each element of the CMFP showed moderate to strong correlations with the total CMFP score and showed Cronbach's alpha of 0.303 and 0.358 in both populations. The Spearman's r and kappa values between the CMFP and the FFP were 0.795 and 0.663 in the CHARLS, and 0.676 and 0.537 in the pilot study. The areas under the curve (AUC) were 0.936 and 0.928 in the 2 studies, respectively. In addition, frailty assessed by the CMFP significantly predicted future incidence of outcomes, including all-cause mortality, activities of daily living (ADL)/instrumental ADL disability, hospitalization, and depression.

CONCLUSIONS AND IMPLICATIONS

The study demonstrated the CMFP as a valid tool, particularly highlighting its excellent predictive ability on outcomes. The 5t-CST may act as a viable alternative test for assessing slowness. The CMFP can be systematically integrated into preclinical practice to identify frail individuals, especially within constrained spaces.

Nutritional and inflammation factors associated with current frailty level and effect of co-morbidities on the progression of frailty

AIM

Frailty is defined as extreme vulnerability, a syndrome that exposes the individual to a higher risk of disability. While risk factors for frailty have been gradually uncovered, the full identification of biochemical factors and co-morbidities influencing frailty remains incomplete.

METHODS

Cross-sectional and longitudinal analyses were performed to elucidate the risk factors for the prevalence and progression of frailty. The study included 1035 Japanese female outpatients. At baseline, biochemical markers were measured. Co-morbidities included diabetes mellitus, dyslipidemia, hypertension, vertebral osteoarthritis, and osteoporosis. Frailty levels were assessed using frailty scores ranging from 0 to 5. Prevalence of frailty was judged by a score of 3 or above, and progression was judged by an increase in the frailty score during the observation period. Multiple regression analysis was used for the cross-sectional analysis, and the Cox hazard model was used for the longitudinal analysis.

RESULTS

Of the 1035 selected participants, 212 were diagnosed with frailty. Advanced age and log IL-6 and branched-chain amino acids (BCAA) levels were significant independent risk factors for frailty. Subjects were followed for 7.7 ± 5.9 years and progression was observed in 130 subjects. Older age, the absence of hyperlipidemia, the presence of osteoporosis, and lower frailty scores were identified as significant risk factors for frailty progression.

CONCLUSIONS

Inflammatory and nutritional markers exhibited significant associations with the current frailty status, whereas co-morbidities such as osteoporosis or hyperlipidemia emerged as independent risk or protective factors of future frailty progression. Geriatr Gerontol Int 2024; 24: 523-528.

Fried Frailty Phenotype Questionnaire scores and postoperative patient-reported outcomes of patients undergoing major abdominal cancer surgery: A secondary analysis

AIM

This study aimed to evaluate the effects of Fried Frailty Phenotype Questionnaire (FFPQ) scores on patient-reported postoperative outcomes.

METHODS

This secondary analysis of a prospective observational study included 230 inpatients aged ≥65 years undergoing elective abdominal cancer surgery. The primary outcome was the Quality of Recovery-15 score on postoperative days 2, 4 and 7. The secondary outcomes included disability-free survival, defined as a 12-item World Health Organization Disability Assessment Schedule 2.0 score of <16% at 3 months. The associations of the FFPQ scores, ranging from 0 (robust) to 5 (frailty), with the primary and secondary outcomes were assessed using multiple analysis.

RESULTS

After confirming the linearity of the FFPQ score for the outcomes, multiple regression analysis adjusted for prominent factors showed that the FFPQ score was a significant factor influencing the decrease in the Quality of Recovery-15 score on postoperative day 2 (β = -2.67, 95% confidence interval -5.20, -0.15), 4 (β = -3.54, 95% confidence interval -5.77, -1.30) and 7 (β = -3.70, 95% confidence interval -5.75, -1.65). The adjusted odds ratio of the FFPQ score for disability-free survival postoperatively was 0.66 (95% confidence interval 0.49-0.90).

CONCLUSIONS

Patients with higher FFPQ scores before elective major abdominal cancer surgery were likely to have lower postoperative Quality of Recovery-15 scores and poor disability-free survival. Geriatr Gerontol Int 2024; 24: 464-469.

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

BACKGROUND

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.

SUBJECTS AND METHODS

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.

RESULTS

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.

CONCLUSION

Community-dwelling older adults who did not meet the MVPA criteria, regardless of sleep quality, had a higher prevalence of physical frailty.

The measurement properties and feasibility of FRAIL scale in older adults: A systematic review and meta-analysis

Frailty is a prevalent condition amongst older adults, significantly affecting their quality of life. The FRAIL tool has been purposefully designed for clinical application by assisting healthcare professionals in identifying and managing frailty-related issues in older adults, making it a preferred choice for assessing frailty across diverse older populations. This review aimed to synthesize the measurement properties and feasibility of FRAIL. Guided by COSMIN guidelines, seven databases were searched from inception to 31 Mar 2023. The measurement properties were extracted for quality appraisal of the populations in the studied samples. Where possible, random-effects meta-analysis and meta-regression were used for quantitative synthesis. Eighteen articles containing 273 tests were drawn from 14 different populations. We found that populations testing for criterion validity had high-quality ratings, while construct validity ratings varied based on health status and geographical region. Test-retest reliability had sufficient quality ratings, while scale agreement had sufficient ratings in only four out of 14 populations tested. Responsiveness ratings were insufficient in seven out of eight populations, with inconsistent ratings in one population. Our analysis of missing data across three articles showed a 16.3% rate, indicating good feasibility of the FRAIL. FRAIL is a feasible tool for assessing frailty of older adults in community settings, with good criterion validity and test-retest reliability. However, more research is needed on construct validity and responsiveness.

Association between preoperative frailty and surgical Apgar score in abdominal cancer surgery: a secondary analysis of a prospective observational study

INTRODUCTION

The surgical Apgar score is useful for predicting postoperative morbidity and mortality. However, its applicability in frail patients with minimal hemodynamic variation remains unknown. This study aimed to investigate the association between frailty and surgical Apgar score.

METHODS

This secondary analysis included 210 patients ≥ 65 years of age undergoing elective major abdominal surgery for cancer. Frailty was assessed using the Fried Frailty Phenotype Questionnaire and defined as a total score of ≥ 3. The surgical Apgar score (range, 0-10; including mean blood pressure, heart rate, and blood loss volume) was compared between patients with or without frailty using the Mann-Whitney U test. Postoperative severe complications and length of postoperative stay were compared between patients with surgical Apgar scores ≤ 7 and > 7.

RESULTS

Among the included patients, 45 were classified as frail. The median [1st quartile, 3rd quartile] surgical Apgar scores in patients with and without frailty were 7.0 [7.0, 8.0] and 8.0 [7.0, 8.0], respectively (P = 0.03). Patients with surgical Apgar score ≤7 had a higher incidence of serious postoperative complications (P = 0.03) and longer hospital stays (P < 0.001) compared with patients with surgical Apgar score >7.

CONCLUSION

Frail patients have lower SAS, and patients with lower SAS have higher postoperative complication rates and longer hospital stays in patients who underwent cancer surgery.

Effects of preoperative nutritional status on postoperative quality of recovery: a prospective observational study

Quality of Recovery-15 (QoR-15) has received attention as a postoperative patient-reported outcome measure. Preoperative nutritional status has negative effects on postoperative outcomes; however, these associations have not yet been investigated. We included inpatients aged ≥ 65 years who underwent elective abdominal cancer surgery under general anaesthesia between 1 June 2021 and 7 April 2022 at our hospital. Preoperative nutritional status was assessed using the Mini Nutritional Assessment Short-Form (MNA-SF), and patients with an MNA-SF score ≤ 11 were categorised into the poor nutritional group. The outcomes in this study were the QoR-15 scores at 2 d, 4 d and 7 d after surgery, which were compared between groups by unpaired t test. Multiple regression analysis was applied to assess the effects of poor preoperative nutritional status on the QoR-15 score on postoperative day 2 (POD 2). Of the 230 included patients, 33·9 % (78/230) were categorised into the poor nutritional status group. The mean QoR-15 value was significantly lower in the poor nutritional group than in the normal nutritional group at all postoperative time points (POD 2:117 v. 99, P = 0·002; POD 4:124 v. 113, P < 0·001; POD 7:133 v. 115, P < 0·001). Multiple analyses showed that poor preoperative nutritional status was associated with the QoR-15 score on POD 2 (adjusted partial regression coefficient, -7·8; 95 % CI -14·9, -0·72). We conclude that patients with a poor preoperative nutritional status were more likely to have a lower QoR-15 score after abdominal cancer surgery.

Quality of recovery in hospital and disability-free survival at three months after major abdominal surgery

BACKGROUND

The Quality of Recovery-15 (QoR-15) and 12-item World Health Organization Disability Assessment Schedule 2.0 scales are post-surgery patient-reported outcome measures. We aimed to evaluate the association between immediate in-hospital postoperative recovery and mid-term disability-free survival (DFS) after discharge.

METHODS

We conducted a prospective observational study at a university hospital and enrolled 260 patients aged ≥ 65 years with cancer who were undergoing elective major abdominal surgery. The association between poor postoperative recovery, defined as a QoR-15 score < 90 on postoperative day (POD) 2, and the DFS three months later was assessed using Fisher's exact test. The odds ratio of poor recovery on POD 2 to DFS was calculated using multiple logistic regression analysis adjusted for prominent factors (age, preoperative frailty, preoperative DFS, surgical duration, and intraoperative blood loss volume).

RESULTS

A total of 230 patients completed the 3-month follow-up. On POD 2, 27.3% of the patients (63/230) had poor recovery. A greater number of patients without poor recovery on POD 2 had DFS at three months after surgery (79.6%) than those with poor recovery (65.1%) (P = 0.026). The adjusted odds ratio of poor recovery on POD 2 to DFS at three months was 0.481 (95% CI [0.233, 0.994]).

CONCLUSIONS

Patients with poor recovery on POD 2 were less likely to have DFS three months after abdominal surgery. These findings may allow for early and effective interventions to be initiated based on each patient's condition after abdominal surgery.

Associations between various types of activity and physical frailty in older Japanese: a cross-sectional study

BACKGROUND

Physical activity is known to help prevent physical frailty, but it is not clear which physical activities practiced alone or in combination are most closely associated with a lower risk of physical frailty. We investigated differences in the associations of exercise habit, social participation, and moderate-to-vigorous physical activity (MVPA) with physical frailty and its components among community-dwelling older Japanese adults.

SUBJECTS AND METHODS

A total of 831 older adults participated in this cross-sectional study. Physical frailty was defined based on the Fried et al. criteria. Exercise habit was defined as exercising ≥ 30 min per day for ≥ 2 days per week for ≥ 1 year. Social participation was defined as participating in community activities ≥ 1/week. MVPA was defined as ≥ 300 min/week of moderate physical activity (MPA) or 150 min/week of vigorous physical activity (VPA). We classified the participants into eight groups according to the presence/absence of these activities, and we performed a logistic regression analysis to investigate the association between different activities, both alone and in combination, and physical frailty.

RESULTS

The prevalence of physical pre-frailty + frailty was 74.8% in the None group, 65.0% in the Exercise habit group, 76.3% in the Social participation group, 56.5% in the MVPA group, 58.7% in the Exercise habit + Social participation group, 44.0% in the Exercise habit + MVPA group, 41.3% in the Social participation + MVPA group, and 38.0% in the All group. Compared to the None group, the groups in which participants were engaged in any combination of two or more types of activity, as well as the MVPA-alone group had significantly lower risks of physical pre-frailty + frailty.

CONCLUSION

Community-dwelling older Japanese adults who engaged in MVPA or any combination of two or more types of physical activity as defined herein had lower risks of physical pre-frailty and frailty.

The Frail Scale - A Risk Stratification in Older Patients with Acute Coronary Syndrome

Purpose

The aim of this study was to explore the impact of frailty on in-hospital adverse outcomes and net adverse clinical events (NACE) in older patients with acute coronary syndrome.

Patients and Methods

This observational study included elderly patients (≥60 years old), diagnosed with acute coronary syndrome (ACS) at admission from February 2021 to August 2021. The primary outcome was net adverse clinical events (NACE) defined as a composite of all-cause mortality, stroke, and major bleeding. Secondary outcome was in-hospital adverse outcomes including arrhythmia, acquired pneumonia, stroke, major bleeding, and all-cause mortality. Frailty was assessed using the Frail scale (FS). Data about socio-demographics, comorbidities, body mass index, ACS type, coronary angiography, left ventricular ejection fraction, and length of hospital stay were also collected. Univariate and multivariate logistic regressions were employed to identify the potential association between frailty and outcomes.

Results

Of the 116 ACS patients, 38 patients were frail (32.76%). Frail subjects were more often female (50%) and older (p < 0.01) and had higher rates of in-hospital adverse outcomes (OR = 2.37, p = 0.05) and NACE (OR = 7.12; p < 0.01). In univariate analysis, the increased frail score was significantly associated with increased odds of NACE (unadjusted OR = 1.98, 95% CI 1.17-3.35 for each score increase in Frail Score). In multivariable logistic regression, models controlling for age, gender, PCI, LVEF, and coronary angiography (adjusted OR 2.19, 95% CI 1.12-4.29 for each score increase in Frail Score).

Conclusion

This study revealed the reference data of frailty assessment in older patients with ACS in Vietnam. Our result indicated that over 30% of ACS older patients presented with frailty which was associated with an increased risk of in-hospital adverse outcomes and NACE. This study also provided promising information about the simple FRAIL scale's potential role in the risk stratification of older patients with ACS.

Development and Validation of the Chinese Frailty Screening Scale: A Study among Community-Dwelling Older Adults in Shanghai

BACKGROUND

Based on intrinsic capacity (IC) as defined by the World Health Organization, an accelerated decline may be an important precursor of frailty among older adults; however, there is a lack of validated instruments that both screen for frailty and monitor IC. This study aims to develop a comprehensive and acculturative frailty screening scale to determine healthy aging among older Chinese adults.

SETTING AND PARTICIPANTS

A cross-sectional and a cohort study both based on community-dwelling older adults aged 65 and older.

METHODS

This study mainly consisted of two parts. First, the selection and revision of 20 items related to frailty based on a literature review, expert consultation, and stakeholder analysis; second, a cross-sectional study was conducted to simplify the scale and test the reliability and validity of the new frailty screening tool. The fatigue, resistance, ambulation, illness, and loss of weight (FRAIL) scale, the Tilburg frailty indictor (TFI), and a 49-item Frailty Index (FI) were investigated as criteria. Additionally, a cohort study in Shanghai was conducted to verify the predictive validity of the new screening scale. The disability measured by the activity of daily living (ADL), instrumental activity of daily living (IADL) and all-cause mortality were documented as outcomes.

RESULTS

A 10-item Chinese frailty screening scale (CFSS-10) was successfully developed and validated. It presented a Cronbach's α of 0.63 and an intraclass correlation coefficient of 0.73, which indicated good reliability. Taking the other frailty tools as criteria, Kappa values of 0.54-0.58 and an area under the curve of 0.87-0.91 showed good validity. The results of the log-binomial and Poisson models showed a high score, which predicted a higher risk of disability and all-cause mortality. An optimal cut-off point of 5 gave an excellent prediction of one-year disability.

CONCLUSIONS

The CFSS-10 has good validity and reliability as a quick and acculturative frailty screening scale for community-dwelling older adults in Shanghai. It may also supplement existing frailty screening tools.

Association between oral function and physical pre-frailty in community-dwelling older people: a cross-sectional study

BACKGROUND

Few studies have examined the relationship between oral functions and the physical pre-frailty status, classified using physical function tests. This cross-sectional study aimed to clarify this association among community-dwelling older people from the Itoshima Frail Study in Itoshima Fukuoka Prefecture.

METHODS

Of the 1,555 individuals invited to join the study, 381 (188 males and 193 females) enrolled. Their physical pre-frailty was assessed with a classification system consisting of two physical indicators (fatigue and unintentional weight loss, determined with a questionnaire), two functional components (declined walking speed and muscle weakness, determined using a body function measuring instrument), and declined physical activity (examined using a triaxial accelerometer). Subsequently, the individuals were classified into three groups: robust, pre-frailty, and frailty. Along with the number of teeth remaining, oral functions, such as masticatory performance, tongue pressure strength, and oral diadochokinesis (ODK), were examined. Data regarding social activity and exercise habits were collected, and the individuals' body compositions were measured. Odds ratios (ORs) and 95% confidence intervals (CIs) for the physical pre-frailty were calculated using logistic regression models.

RESULTS

In this study, 126 (33%) participants presented with physical pre-frailty. The participants in the robust group were younger, had stronger maximum handgrip strength, and walked faster than those in the physical pre-frailty group (p < 0.001). The robust group presented with better oral functions (masticatory performance, p = 0.015; oral ODK /ta/, p = 0.004). The physical pre-frailty status was significantly associated with age (OR, 1.111; 95% CI, 1.048-1.178; p < 0.001), masticatory performance (OR, 0.819; 95% CI, 0.680-0.986; p = 0.035), low ODK/ta/ (OR, 1.864; 95% CI, 1.069-3.250; p = 0.028), and low social activity (OR, 2.273; 95% CI, 1.308-3.951; p = 0.004).

CONCLUSION

This study indicated that older people with higher age, lower anterior tongue movement, lower masticatory performance, and lower social activity are positively associated with physical pre-frailty.

Association between Walking Habit and Physical Frailty among Community-Dwelling Older Adults

The aim of this cross-sectional study was to determine whether older adults who practice walking have a lower risk of physical frailty than those who do not. The study subjects were 846 older adults and were not certified as needing support or nursing care. The subjects were classified as being physically frail or pre-frail or being robust, according to the revision of the Cardiovascular Health Study criteria. We classified the subjects by questionnaire into a no-exercise group, walking-only group, walking plus other exercise group, and exercise other than walking group. In logistic regression analyses, the odds ratio (OR) and 95% confidence interval (95%CI) were shown. Compared to the no-exercise group, the OR (95%CI) for physical frailty was 0.85 (0.48–1.49) for the walking-only group, 0.54 (0.36–0.83) for the walking plus other exercise group, and 0.67 (0.47–0.97) for the exercise other than walking group. In the components of physical frailty, the walking plus other exercise group and the exercise other than group had significantly lower ORs for exhaustion. Older adults who only practiced walking as an exercise do not have lower risks of physical frailty and pre-frailty. Older adults who combine walking with other exercises or practice non-walking exercises have lower risks of them.

Self-reported Frailty Screening Tools: Comparing Construct Validity of the Frailty Phenotype Questionnaire and FRAIL

OBJECTIVES

We examined the construct validity of 2 self-reported frailty questionnaires, the Frailty Phenotype Questionnaire (FPQ) and FRAIL, against the Cardiovascular Health Study frailty phenotype (CHS-FP).

DESIGN

Cross-sectional data analysis of longitudinal prospective cohort study.

SETTINGS AND PARTICIPANTS

We included data from 230 older adults (mean age: 67.2 ± 7.4 years) from the "Longitudinal Assessment of Biomarkers for characterization of early Sarcopenia and Osteosarcopenic Obesity in predicting frailty and functional decline in community-dwelling Asian older adults Study" (GeriLABS 2) recruited between December 2017 and March 2019.

METHODS

We compared area under receiver operating characteristic curves (AUC), agreement, correlation, and predictive validity against outcome measures (Short Physical Performance Battery, 5 times repeat chair stand [RCS-5], Frenchay activities index, International Physical Activity Questionnaire, life-space assessment, Social Functioning Scale 8 [SFS-8], EuroQol-5 dimensions [utility value]) using logistic regression adjusted for age, gender, and vascular risk factors. We examined concurrent validity across robust versus prefrail/frail for inflammatory blood biomarkers (tumor necrosis factor receptor 1 and C-reactive protein [CRP]) and dual-energy x-ray absorptiometry body composition (bone mineral density (BMD); appendicular lean mass index [ALMI], and fat mass index [FMI]).

RESULTS

Prevalence of prefrail/frail was 25.7%, 14.8%, and 48.3% for FPQ, FRAIL, and CHS-FP, respectively. Compared with FRAIL, FPQ had better diagnostic performance (AUC = 0.617 vs 0.531, P = .002; sensitivity = 37.8% vs 18.0%; specificity = 85.6% vs 88.2%) and agreement (AC1-Stat = 0.303 vs 0.197). FPQ showed good predictive validity (RCS-5: odds ratio [OR] 2.38; 95% CI: 1.17-4.86; International Physical Activity Questionnaire: OR 3.62; 95% CI:1.78-7.34; SFS-8: OR 2.11; 95% CI: 1.64-5.89 vs FRAIL: all P > .05). Only FRAIL showed concurrent validity for CRP, compared with both FPQ and FRAIL for TNF-R1. FRAIL showed better concurrent validity for BMD, FMI, and possibly ALMI, unlike FPQ (all P > .05).

CONCLUSIONS AND IMPLICATIONS

Our results support complementary validity of FPQ and FRAIL in independent community-dwelling older adults. FPQ has increased case detection sensitivity with good predictive validity, whereas FRAIL demonstrates concurrent validity for inflammation and body composition. With better diagnostic performance and validity for blood biomarkers and clinical outcomes, FPQ has utility for early frailty detection in the community setting.

Effect of Isometric Tongue Lifting Exercise on Oral Function, Physical Function, and Body Composition in Community-Dwelling Older Individuals: A Pilot Study

INTRODUCTION

It is known that oral frailty is one of the risk factors for physical frailty. Therefore, early detection, appropriate treatment, and prevention of oral frailty are really important. Tongue lifting exercise has been identified as a well-known method for improving decreased tongue pressure, one of the factors for oral frailty. However, few reports have investigated how tongue-strengthening exercises affect physical function and body composition. The aim of this study was to investigate the effects of isometric tongue lifting exercises on oral function, physical function, and body composition.

METHODS

Participants were 49 elderly people aged 68-79 years, who had previously participated in the "Itoshima Frail Study." Participants performed isometric tongue lift exercises for 3 months. Oral function (tongue pressure and oral diadocokinesis), physical function (grip strength, open-eyed one-leg standing, sit-to-stand motion time, 5-m gait speed, and 3-m Timed up and go [TUG]), and body composition were measured at baseline and post-intervention, and the extent of changes in each item was statistically analyzed. Furthermore, participants were divided into physical frailty/pre-frailty and robust groups based on the Japanese version of the frail scale proposed by [BMC Geriatr. 2015 Apr;15:36] and were compared in terms of the extent of changes in each item baseline and the post-intervention.

RESULTS

After the intervention, oral function increased significantly together with a significant improvement in physical function, open-eyed one-leg standing time, sit-to-stand motion, and 3-m TUG. For body composition, visceral fat level and basal metabolic rate decreased significantly. Although no significant change in body composition was observed in the physical frailty/pre-frailty group after the intervention, significant improvements in several items were observed in the robust group.

CONCLUSION

Isometric tongue lifting exercise can effectively improve oral function. Furthermore, it might affect physical function and body composition.

Effect of number of medications and use of potentially inappropriate medications on frailty among early-stage older outpatients

Background

Frailty is an urgent concern among an aging population worldwide. However, the relationship between frailty and number and types of medications has not been studied in detail among early-stage older patients, and it is unclear what prescriptions may have a role in preventing frailty. This study aimed to clarify the effects of number of medications and use of potentially inappropriate medications (PIMs) on frailty among early-stage older outpatients in Japan.

Methods

A cross-sectional study was undertaken. Frailty scores and medications of outpatients aged 65–74 years who regularly visited community pharmacies were investigated. Frailty scores were classified as 0 (non-frailty), 1–2 (pre-frailty), and ≥ 3 (frailty). The association between frailty and number of medications was analyzed by age and compared between PIM use and non-use groups. The proportion of patients who used PIMs was also analyzed by frailty score.

Results

Of 923 older outpatients, 49 (5.3%) and 318 (34.5%) patients had frailty and pre-frailty scores, respectively. The numbers of medications among patients with pre-frailty and frailty were significantly higher than among those with non-frailty (p <  0.001 for both). A similar increase was shown for PIM use groups aged 69–71 and 72–74 years, but not for the PIM use group aged 65–68 years and all groups without PIM use. An increasing linear trend was observed for the relationship between the proportion of patients who used any PIM, as well as some subcategories of PIMs (such as NSAIDs, benzodiazepines, loop diuretics and antithrombotic drugs) and frailty score.

Conclusions

Unnecessary medication use among early-stage older outpatients, especially patients aged ≥69 years who use PIMs and many medications, seems to be associated with frailty, but further research is needed to confirm these findings.

Nutritional domains in frailty tools: Working towards an operational definition of nutritional frailty

Different methods have been proposed for the assessment of the nutritional status in frailty phenotypes. In the present narrative review article, we have summarized the number and specifications of nutritional items in existing frailty tools, in order to develop a possible means of assessment and operational definition of the nutritional frailty phenotype. In six different databases until December 2019, we searched for original articles regarding frailty tools (i.e., scales, indexes, scores, questionnaires, instruments, evaluations, screening, indicators), analyzing each tool regarding nutritional items. We identified 160 articles describing 71 frailty tools. Among the selected frailty tools, 54 were community-based (70 %), 17 hospital-based (22 %), 4 validated in long-term care institutions for older adults (LTCIOA) (5.1 %) and 2 validated in both community- and hospital-based settings, including LTCIOA (2.5 %). Fifty-two of these tools (73 %) included at least one nutritional item. Twenty-two (42 %) reported two or more nutritional items. The items were grouped in the following categories: A) anthropometric measurements, B) laboratory measurements, and C) other nutritional-related measurements. Anthropometric measurements stood out compared to all other items. Nutritional items are included in the majority of frailty tools, strengthening the concept that they may have a direct implication on an increased risk of adverse health-related outcomes in frail subjects. This supports the development of the concept of nutritional frailty as an independent frailty phenotype. Subsequent steps will be to assess the contribution of each nutritional item to a possible operational definition of nutritional frailty and define the items that may best identify this new frailty phenotype.
