Common and different characteristics among combinations of physical frailty and sarcopenia in community-dwelling older adults: The Korean Frailty and Aging Cohort Study.

Physical frailty and sarcopenia are geriatric syndromes associated with adverse health outcomes. However, the common and different conditions associated with physical frailty and sarcopenia remain unclear. This study aimed to compare the clinical characteristics of older adults with physical frailty and sarcopenia. This cross-sectional study analyzed 2028 community-dwelling older adults, aged 70-84 years (mean age 75.9 ± 4.0 years; 50.1% men). Physical frailty was defined using the Fried frailty phenotype, whereas sarcopenia was defined using the Asian Working Group for Sarcopenia 2014 and 2019 criteria. The prevalence of physical frailty was 5.5%, whereas that of sarcopenia, using the Asian Working Group for Sarcopenia 2014 and 2019, was 9.1% and 17.5%, respectively. The concordance of physical frailty with sarcopenia was higher in the Asian Working Group for Sarcopenia 2019 criteria than in 2014. Frail-only participants had a higher incidence of disability, cognitive dysfunction, poor self-perceived health, and depressive symptoms than the sarcopenic-only participants. Frail-and-sarcopenic participants showed a lower body mass index (≥23 kg/m2 ) than frail-only participants. Furthermore, in frail-and-sarcopenic participants, recurrent falls (16.9% vs 5.5%) were higher than in the neither-frail-nor-sarcopenic participants; falls with fracture (11.5% vs 1.7%) and fear of falling (59.0% vs 36.7%) were higher in frail-and-sarcopenic participants than in sarcopenic-only participants. This study showed significant differences between physical frailty and sarcopenia among community-dwelling older adults. Older adults with physical frailty and sarcopenia were more likely to have higher fall-related outcomes than the others. Geriatr Gerontol Int 2022; 22: 42-49.

Instruments to assess sarcopenia and physical frailty in older people living in a community (care) setting: similarities and discrepancies.

Both sarcopenia and physical frailty are geriatric syndromes causing loss of functionality and independence. This study explored the association between sarcopenia and physical frailty and the overlap of their criteria in older people living in different community (care) settings. Moreover, it investigated the concurrent validity of the FRAIL scale to assess physical frailty, by comparison with the widely used Fried criteria. Data were retrieved from the cross-sectional Maastricht Sarcopenia Study (MaSS). The study was undertaken in different community care settings in an urban area (Maastricht) in the south of the Netherlands. Participants were 65 years or older, gave written informed consent, were able to understand Dutch language, and were not wheelchair bound or bedridden. Not applicable. Sarcopenia was identified using the algorithm of the European Working Group on Sarcopenia in Older People. Physical frailty was assessed by the Fried criteria and by the FRAIL scale. Logistic regression was performed to assess the association between sarcopenia and physical frailty measured by the Fried criteria. Spearman correlation was performed to assess the concurrent validity of the FRAIL scale compared with the Fried criteria. Data from 227 participants, mean age 74.9 years, were analyzed. Sarcopenia was identified in 23.3% of the participants, when using the cutoff levels for moderate sarcopenia. Physical frailty was identified in 8.4% (≥3 Fried criteria) and 9.3% (≥3 FRAIL scale criteria) of the study population. Sarcopenia and physical frailty were significantly associated (P = .022). Frail older people were more likely to be sarcopenic than those who were not frail. In older people who were not frail, the risk of having sarcopenia increased with age. Next to poor grip strength (78.9%) and slow gait speed (89.5%), poor performance in other functional tests was common in frail older people. The 2 physical frailty scales were significantly correlated (r = 0.617, P < .001). Sarcopenia and physical frailty were associated and partly overlap, especially on parameters of impaired physical function. Some evidence for concurrent validity between the FRAIL scale and Fried criteria was found. Future research should elicit the value of combining sarcopenia and frailty measures in preventing disability and other negative health outcomes.

Screening for Frailty and Sarcopenia Among Older Persons in Medical Outpatient Clinics and its Associations With Healthcare Burden.

With an aging population and increase in multimorbidity, the importance of screening for frailty and sarcopenia has become a public health priority. Several tools to do so exist. This study aimed to examine whether the SARC-F and Edmonton frail screening tools are useful in clinical practice to identify at-risk patients for negative health outcomes who would benefit from intervention. This is a cross-sectional study of patients attending medical specialist outpatient clinics at the National University Hospital, Singapore from May 2015 to February 2016. Frailty and sarcopenia were identified using the Edmonton Frail Scale and SARC-F questionnaires, respectively. Other clinically relevant data including basic demographics, presence of caregiver, number of follow-ups, medications and hospital readmissions in the past 1 year, Charlson comorbidity index, and modified Barthel index were collected from chart review. A total of 115 patients 65 years old and older were screened. Of the sample, 44.3% (n = 51) of patients were sarcopenic, whereas 27.0% (n = 31) were classified as frail; 23.5% (n = 27) were both frail and sarcopenic; and 87.1% of frail patients were sarcopenic, whereas 47.1% of sarcopenic patients were frail. Sarcopenia and frailty were associated with a higher Charlson comorbidity index, higher likelihood of requiring a caregiver, more medical specialty follow-ups, polypharmacy, more than 2 hospital admissions within a year, a higher number of falls and falls with serious consequences. This affected their perceived health status with 50.0% of robust patients rating their health excellent compared with 19.6% of sarcopenic patients (P < .001), 9.7% of frail patients (P < .001) and sarcopenic and frail patients scoring the lowest with 3.7% (P < .001). The prevalence of frailty and sarcopenia among older adults attending medical outpatient clinic is high. Both syndromes are predictors of recurrent hospital admissions, polypharmacy, multiple medical clinic appointments, higher rate of falls, and falls with serious consequences. Early identification of older adults at risk of adverse health outcomes would aid in instituting timely intervention to reduce healthcare burden and improve quality of life.

Low back pain is closely associated with frailty but not with sarcopenia: Cross-sectional study of rural Japanese community-dwelling older adults.

We speculated that low back pain, which is the most common ailment in older adults, is associated with frailty and/or sarcopenia and contributes to the progression of either condition. Our objective was to evaluate the relationship between low back pain, sarcopenia and frailty in rural Japanese community-dwelling older adults. We recruited 730 participants aged ≥65 years who underwent a comprehensive health examination between November 2016 and December 2018. The Oswestry Disability Index (ODI) was used to assess low back pain quantitatively, and scores were compared for the frail groups determined by the Japanese version of Cardiovascular Health Study, and the sarcopenia groups as determined by the Asian Working Group for Sarcopenia 2019. Among 730 participants, the prevalence of low back pain was 57.8%. There were significant differences in the ODI scores between the robust, prefrail and frail groups (P < 0.001). In contrast, there were no significant differences in the ODI scores among the robust, low appendicular skeletal muscle and sarcopenia groups. Logistic regression analysis showed that the prevalence of low back pain and the ODI scores were significantly associated with frailty after adjustment for age, sex and body mass index (odds ratio 3.41, 95% confidence interval 1.39-8.39, P = 0.008, and odds ratio 1.06, 95% confidence interval 1.04-1.09, P < 0.001, respectively). To the best of our knowledge, this study is the first to show the close association between low back pain and frailty, and suggests that not only the decline in physical function but also neuropsychiatric factors, including chronic pain, constitute a vicious cycle of frailty in community-dwelling older adults.
