Intrinsic capacity and hospitalization among older adults: a nationally representative cross-sectional study.

PURPOSE: Monitoring intrinsic capacity (IC) in community-dwelling older people can be potentially used to alert for adverse health outcomes. However, whether there is an association between IC and hospitalization has yet to be fully explored. This study aimed to investigate the association of the IC composite measure and its 5 domains with hospitalization in the previous year and length of hospital stay. METHODS: We conducted cross-sectional analyses using data from a representative sample of community-dwelling adults (≥ 65 years). We assessed the IC domains (vitality, locomotor, cognitive, sensory, and psychological) using validated self-reported information and performance tests. We calculated standardized estimated scores (z scores) for IC composite measure and domains and conducted multivariate logistic and ordinal regressions. The primary outcomes were hospitalizations in the previous year and length of hospital stay. RESULTS: In a sample of 5354 participants (mean age = 73 ± 6 years), we found that participants with high IC composite z scores were less likely to have experienced hospitalization in the previous year (OR = 0.51; 95% CI = 0.44-0.58). Among those who were hospitalized, high IC scores were associated with short stays (OR = 0.87; 95% CI = 0.80-0.95). Cognitive and psychological domains were associated with hospitalizations, and the locomotor domain was related to length of hospital stay. The vitality domain was associated with both outcomes. CONCLUSION: IC as a composite measure was associated with previous hospitalizations and length of stay. IC can help clinicians identify older people prone to adverse outcomes, prompting preventive integrated care interventions.

Pain symptoms and physical performance in older adults: cross-sectional findings from the International Mobility in Aging Study (IMIAS).

PURPOSE: To analyze the associations between pain and physical performance in different aging contexts. METHODS: Data from 1725 older adults from Canada, Brazil, Colombia, and Albania from the 2014 wave of the IMIAS were used to assess the associations between Back Pain (BP) or Lower Limb Pain (LLP) and physical performance by the Short Physical Performance Battery (SPPB). Three binary logistic regression models adjusted for sex, age, study site, education, income sufficiency, BMI, depressive symptoms, and chronic conditions were used to estimate the associations between LLP or BP and SPPB. The SPPB was classified into good performance (8 points or more) and poor physical performance (< 8 points). RESULTS: The mean age of the older men was 71.2 (± 3.0) and the mean age of the women was 71.2 (± 2.8) years. Older men (72.8%, p < 0.05) and women (86.1%, p-value < 0.05) from Albania had the highest frequencies of self-reported general pain. Older women in Colombia had the highest frequencies of LLP or BP (33.5%, p-value < 0.05). In the fully adjusted logistic regression model, LLP or BP was significantly associated with poor SPPB (OR = 0.48, 0.35 to 0.66 95% CI, p < 0.01). CONCLUSIONS: Pain symptoms are associated with reduced physical performance in older people, even when adjusted for other clinical and sociodemographic factors. Protocols for aiming to increase the level of physical activity to manage pain should be incorporated into health care strategies.

Spectrochemical analysis of blood combined with chemometric techniques for detecting osteosarcopenia.

Among several complications related to physiotherapy, osteosarcopenia is one of the most frequent in elderly patients. This condition is limiting and quite harmful to the patient's health by disabling several basic musculoskeletal activities. Currently, the test to identify this health condition is complex. In this study, we use mid-infrared spectroscopy combined with chemometric techniques to identify osteosarcopenia based on blood serum samples. The purpose of this study was to evaluate the mid-infrared spectroscopy power to detect osteosarcopenia in community-dwelling older women (n = 62, 30 from patients with osteosarcopenia and 32 healthy controls). Feature reduction and selection techniques were employed in conjunction with discriminant analysis, where a principal component analysis with support vector machines (PCA-SVM) model achieved 89% accuracy to distinguish the samples from patients with osteosarcopenia. This study shows the potential of using infrared spectroscopy of blood samples to identify osteosarcopenia in a simple, fast and objective way.

Barriers to and facilitators of populational adherence to prevention and control measures of COVID-19 and other respiratory infectious diseases: a qualitative evidence synthesis.

AIMS: To summarise the evidence on barriers to and facilitators of population adherence to prevention and control measures for coronavirus disease 2019 (COVID-19) and other respiratory infectious diseases. METHODS: A qualitative synthesis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis and the Cochrane Effective Practice and Organization of Care: Qualitative Evidence Synthesis. We performed an electronic search on MEDLINE, Embase and PsycINFO from their inception to March 2023. RESULTS: We included 71 studies regarding COVID-19, pneumonia, tuberculosis, influenza, pertussis and H1N1, representing 5966 participants. The measures reported were vaccinations, physical distancing, stay-at-home policy, quarantine, self-isolation, facemasks, hand hygiene, contact investigation, lockdown, infection prevention and control guidelines, and treatment. Tuberculosis-related measures were access to care, diagnosis and treatment completion. Analysis of the included studies yielded 37 barriers and 23 facilitators. CONCLUSIONS: This review suggests that financial and social support, assertive communication, trust in political authorities and greater regulation of social media enhance adherence to prevention and control measures for COVID-19 and infectious respiratory diseases. Designing and implementing effective educational public health interventions targeting the findings of barriers and facilitators highlighted in this review are key to reducing the impact of infectious respiratory diseases at the population level.

Fourier-Transform Infrared Spectroscopy as a Screening Tool for Osteosarcopenia in Community-Dwelling Older Women.

Osteosarcopenia is a complex geriatric syndrome characterized by the presence of both sarcopenia and osteopenia/osteoporosis. This condition increases rates of disability, falls, fractures, mortality, and mobility impairments in older adults. The purpose of this study was to analyze the Fourier-transform infrared (FTIR) spectroscopy diagnostic power for osteosarcopenia in community-dwelling older women (n = 64; 32 osteosarcopenic and 32 non-osteosarcopenia). FTIR is a fast and reproducible technique highly sensitive to biological tissues, and a mathematical model was created using multivariate classification techniques that denoted the graphic spectra of the molecular groups. Genetic algorithm and support vector machine regression (GA-SVM) was the most feasible model, achieving 80.0% of accuracy. GA-SVM identified 15 wave numbers responsible for class differentiation, in which several amino acids (responsible for the proper activation of the mammalian target of rapamycin) and hydroxyapatite (an inorganic bone component) were observed. Imaging tests and low availability of instruments that allow the observation of osteosarcopenia involve high health costs for patients and restrictive indications. Therefore, FTIR can be used to diagnose osteosarcopenia due to its efficiency and low cost and to enable early detection in geriatric services, contributing to advances in science and technology that are potential "conventional" methods in the future.

Allostatic load and physical performance in older adults: Findings from the International Mobility in Aging Study (IMIAS).

OBJECTIVE: This study aimed to evaluate the association between Allostatic Load (AL) and physical performance scores in older adults from four cities in North and South America. METHODS: In this cross-sectional study, data from 1101 volunteers from three countries (Canada, Brazil, and Colombia) from the International Mobility in Aging Study (IMIAS) were used to evaluate the association between AL index and Short Physical Performance Battery (SPPB) scores. Three multiple linear regression models adjusted by age, Socioeconomic Status (SES), chronic conditions, depression symptoms, and Leganés Cognitive Test (LCT) were developed to estimate the independent association between SPPB and AL. Mediation analysis with 2012 LA data and covariates was performed to access the total, direct, and indirect effects of mediation on SPPB scores from 2016. RESULTS: AL and SPPB were inversely associated, with older adults with high allostatic load scoring lower on SPPB (ß: -0.234, Std: 0.033, p-value: <0.001).  Indirect effects were evidenced between age, SES and chronic conditions with AL and SPPB scores. Chronic conditions also had a total effect on SPPB scores and were also mediated by AL. However, indirect effects of depressive symptoms and LCT on SPPB scores mediated by AL were not observed. CONCLUSIONS: Findings from this study support that increased AL index determines worse physical performance states after full adjustments. AL has a mediator role between the number of chronic diseases, depressive symptoms, cognitive status and physical performance. Socioeconomic status also influenced physical scores mediated by the AL index.

Gender-Specific Associations between Late-Life Disability and Socioeconomic Status: Findings from the International Mobility and Aging Study (IMIAS).

Disability is a dynamic process and can be influenced by a sociocultural environment. This study aimed to determine whether the associations between socioeconomic status and late-life disability differ by gender in a multi-sociocultural sample from different countries. A cross-sectional study was developed with 1362 older adults from The International Mobility in Aging Study. Late-life disability was measured through the disability component of the Late-Life Function Disability Instrument. Level of education, income sufficiency and lifelong occupation were used as indicators of SES. The results indicated that a low education level ß = -3.11 [95% CI -4.70; -1.53] and manual occupation ß = -1.79 [95% -3.40; -0.18] were associated with frequency decrease for men, while insufficient income ß = -3.55 [95% CI -5.57; -1.52] and manual occupation ß = -2.25 [95% CI -3.89; -0.61] played a negative role in frequency for women. For both men ß = -2.39 [95% -4.68; -0.10] and women ß = -3.39 [95% -5.77; -1.02], insufficient income was the only factor associated with greater perceived limitation during life tasks. This study suggested that men and women had different late-life disability experiences. For men, occupation and education were associated with a decrease in the frequency of participation, while for women this was associated with income and occupation. Income was associated with perceived limitation during daily life tasks for both genders.

Circumstances and Factors Associated With Falls Among Community-Dwelling Older Adults Diagnosed With Heart Disease Using the International Mobility in Aging Study (IMIAS).

BACKGROUND AND PURPOSE: To identify the circumstances of falls and the factors associated with falls among older adults with cardiovascular disease (CVD). METHODS: Baseline (2012) data from the International Mobility in Aging Study (IMIAS), a cross-sectional study, were used. Falling was measured by the subjective question, "Have you fallen in the last 12 months?" Several subjective questions were asked to obtain information about the circumstances of falls. Potential clinical factors associated with falling were cognitive status, depressive symptoms, physical performance, grip strength, visual acuity, and fear of falling (FOF). These clinical factors were measured respectively with the Leganes Cognitive Test, the Center for Epidemiological Studies Scales Depressive Symptoms, the Short Physical Performance Battery, a Jamar handgrip dynamometer, the Early Treatment Diabetic Retinopathy Study (ETDRS) tumbling E chart placed at 2 m, and the Falls Efficacy Scale-International. A χ 2 test was used to determine whether there were significant differences in fall circumstances among older adults with and without CVD. Two-sample t tests were used to test for any significant differences between older adults with and without CVD. Bonferroni correction was applied to limit type I errors and was corrected to .007. Simple and multiple logistic regressions identified which clinical factors were associated with falling. RESULTS: A total of 429 older adults with CVD (mean age 69.5 ± 2.9) and 431 older adults without CVD (69.2 ± 2.9) participated in the study. Approximately 53% of fallers with CVD had 2 or more falls compared with fallers without CVD (39%). The most common location for falling was at home (43%) for fallers with CVD or in the street (50%) for fallers without CVD. Approximately 9% of fallers with CVD needed to be hospitalized while only 3% of fallers without CVD were admitted to the hospital. Approximately 42% of fallers with CVD had some residual sequelae (eg, being unable to walk around the house or do housework) compared with only 27% of fallers without CVD. Fallers with CVD had significantly ( P value < .007) more depressive symptoms (mean ± SD, 14.7 ± 12.9) and poorer physical performance (8.4 ± 3.0) compared with fallers without CVD (10.1 ± 9.4 and 9.6 ± 2.5, respectively); however FOF was the only significant clinical factor ( P value < .05) associated with falling for older adults with CVD. CONCLUSIONS: Incidence of recurrent falls is higher among older adults with CVD than those without CVD. Circumstances of falls among fallers with CVD differ from those identified among fallers without CVD. Fear of falling was the only predictor of fall history among older adults with CVD. The results suggest the merit of considering FOF when designing prevention and intervention programs to reduce falls among older adults with CVD.

HbA1c and physical performance in older adults from different aging epidemiological contexts: Longitudinal findings of the International Mobility in Aging Study (IMIAS).

OBJECTIVE: This study aimed to assess the longitudinal predictions between glycated hemoglobin A1c (HbA1c) and physical performance scores in different epidemiological contexts of aging. MATERIAL AND METHODS: Longitudinal data of 1,337 older people from three countries (Canada, Brazil and Colombia) of the International Mobility in Aging Study (IMIAS) were used to assess the relationship between HbA1c and Short Physical Performance Battery (SPPB) scores between 2012 and 2016. Linear Mixed Models grouped by sex and adjusted by Age, Study site, Chronic Conditions, Anthropometric Measures, and Inflammatory Level were used to estimate the influence of HbA1c and covariates on SPPB scores. RESULTS: At the IMIAS baseline, Latin American (LA) cities had higher HbA1c averages compared to Canadian cities, with Natal (Brazil) being the city with the highest HbA1c averages in men and women (6.32 ± 1.49; 6,56 ± 1.70 respectively). SPPB scores were significantly lower in LA cities, and older people in Natal had lower SPPB averages in men (9.67 ± 2.38; p-value < 0.05) and women (8.52 ± 2.33; p-value <0.05). In the multivariate mixed linear models of longitudinal analyses, HbA1c was significantly associated with lower SPPB scores in men (ß = -0.25, 95% CI: -0.39 to -0.12, p-value = 0.02) but not in women. CONCLUSION: High HbA1c levels at baseline were longitudinally associated in older adults from different countries, and this association was observed only in men and not in women. This study highlights a possible influence of gender on this relationship.

Socioecological Factors Associated with Hypertension Awareness and Control Among Older Adults in Brazil and Colombia: Correlational Analysis from the International Mobility in Aging Study.

Background: Hypertension awareness and control are understudied among older adults in middle-income countries, with limited work contextualizing awareness and control across layers of influence (individual to the community). Research on hypertension in Latin America is acknowledged as insufficient. Objectives: This study applies the socioecological model (SEM) to examine individual, interpersonal, institutional, and community factors related to hypertension awareness and control in older adults residing in Brazil and Colombia. It identifies groups of older adults more likely to be unaware of their condition and/or to have challenges achieving hypertension control. Methods: We analyzed International Mobility in Aging Study data of 803 community-dwelling adults 65-74 years from study sites in the two most populous countries in South America. The study framework was the socioecological model. Logistic regression models identified factors associated with hypertension awareness and control. Conclusions: Hypertension was prevalent in both samples (>70%), and awareness was high (>80%). Blood pressure control among diagnosed respondents was low: 30% in Brazil and 51% in Colombia. Factors across the socioecological model were associated with awareness and control, with notable differences across countries. Those with diabetes (OR 4.19, 95%CI 1.64-10.71) and insufficient incomes (OR: 1.85, 95%CI 1.03-3.31) were more likely to be aware of their hypertension. In Colombia, those reporting no community activity engagement were less likely to be aware compared to those reporting community activities. In Brazil, it was the opposite. Women (OR 1.66, 95%CI 1.12-2.46) and those reporting strolling shops and stores (OR 1.80, 95% CI 1.09-3.00) were significantly more likely to have their hypertension under control. In Brazil, those 70-75 were significantly less likely to have their hypertension under control compared to their younger counterparts. In Colombia, this was not observed. This paper highlights the importance of theory-based studies within unique Latin American contexts on hypertension and suggests novel opportunities for intervention.

Whole-Body Vibration Associated with Strength Training on the Lower-Limb Blood Flow and Mobility in Older Adults with Type 2 Diabetes: A Study Protocol for a Randomized Controlled Trial.

Vascular endothelium insults caused by high serum glucose levels affect the oxygen supply to tissues, via the microvascular endothelium, resulting in an increased perfusion heterogeneity. These insults may lead to the underuse of blood capillaries, while other vessels are overused and effectively overload their oxygen supply capacity, which eventually causes damages to distal parts of the peripheral nervous system. Therefore, the proprioceptive and exteroceptive feedback information will be gradually lost and contribute to a mobility reduction. This study aims to assess the efficacy of whole-body vibration (WBV) associated with strength training (ST) on lower-limb blood flow and mobility in older adults with type 2 diabetes (DM2). Methods and analyses: This is a protocol (1st version) for Pa single-blind, randomized, controlled clinical trial guided by the SPIRIT guidelines. Our sample will consist of 51 older adults with DM2 randomly allocated to three groups: low frequency WBV (16−26 Hz) associated to ST (G1), WBV sham (G2) and nonintervention control (G3). The study protocol is set for a 12-week (three times per week) schedule. Primary outcomes: skin temperature using infrared thermographic imaging (ITI); mean peripheral arterial blood flow velocity (MBF) by a handheld Doppler ultrasound (DU), and functional mobility by Timed Up and Go (TUG) test. Secondary outcomes: quasi-static posture using the DX100 BTS Smart optoelectronic system, and plantar pressure and body balance using the MPS stabilometric platform. Data will be collected and analyzed at baseline and post-intervention, considering p-value < 0.05 level of significance. The analyses will also be conducted with an intention-to-treat method and effect size. Dissemination: All results will be published in peer-reviewed journals as well as presented in conferences.

HRV Monitoring Using Commercial Wearable Devices as a Health Indicator for Older Persons during the Pandemic.

Remote monitoring platforms based on advanced health sensors have the potential to become important tools during the COVID-19 pandemic, supporting the reduction in risks for affected populations such as the elderly. Current commercially available wearable devices still have limitations to deal with heart rate variability (HRV), an important health indicator of human aging. This study analyzes the role of a remote monitoring system designed to support health services to older people during the complete course of the COVID-19 pandemic in Brazil, since its beginning in Brazil in March 2020 until November 2021, based on HRV. Using different levels of analysis and data, we validated HRV parameters by comparing them with reference sensors and tools in HRV measurements. We compared the results obtained for the cardiac modulation data in time domain using samples of 10 elderly people's HRV data from Fitbit Inspire HR with the results provided by Kubios for the same population using a cardiac belt, with the data divided into train and test, where 75% of the data were used for training the models, with the remaining 25% as a test set for evaluating the final performance of the models. The results show that there is very little difference between the results obtained by the remote monitoring system compared with Kubios, indicating that the data obtained from these devices might provide accurate results in evaluating HRV in comparison with gold standard devices. We conclude that the application of the methods and techniques used and reported in this study are useful for the creation and validation of HRV indicators in time series obtained by means of wearable devices based on photoplethysmography sensors; therefore, they can be incorporated into remote monitoring processes as seen during the pandemic.

Validity and reliability of the Brazilian activities-specific balance confidence scale and determinants of balance confidence in community-dwelling older adults.

Introduction: The Activities-specific Balance Confidence scale is the most used tool to quantify balance confidence, a psychological factor related to balance impairment among older adults. Objective: To investigate the validity and reliability of the original and short versions of the Brazilian Activities-specific Balance Confidence scales, to determine cutoff points for balance impairments and to identify the determinants of balance confidence of community-dwelling older adults.Methods: The validity of both versions of the scales was verified by correlating its results with postural balance, fear of falling and mobility (n = 105). Both scales were administered with a 30 min (interrater reliability, n = 158) and 1-week intervals (intrarater reliability, n = 105). Receiver operating characteristic curve was used to determine the cutoff points, and linear regression was applied to identify the determinants of balance confidence.Results: The Brazilian versions of the scale correlated to postural balance, fear of falling and mobility (p < .05). Excellent interrater (α = 0.946, 95% CI: 0.902-0.976; α = 0.932, 95% CI: 0.918-0.960) and intrarater reliability (α = 0.946, 95% CI: 0.905-0.960; α = 0.952, 95% CI: 0.921-0.965) were found for the original and short versions.  Values of ≤67% (sensitivity: 81%, specificity: 77.4%) and ≤44% (sensitivity: 87.5%, specificity: 82.1%) were observed to identify balance impairments for the original and short versions of the scale. Physical inactivity, fear of falling, imbalance sensation, and number of falls are the main determinants of balance confidence.Conclusion: Both scales are valid and reliable to assess balance confidence. Cutoff points to identify balance impairments were determined and some factors may act as possible predictors of balance confidence.

Fear of Falling Among Community-Dwelling Older Adults with Heart Disease: Findings from an International Mobility in Aging Study (IMIAS).

BACKGROUND: Older adults with heart disease (HD) are more likely to report a higher prevalence of falls compared to those without HD. A knowledge gap currently exists regarding the factors associated with fear of falling (FOF) among older adults with HD. Therefore, this study aimed to estimate FOF and identify factors associated with FOF among older adults with HD. METHODS: Data came from a secondary analysis of the International Mobility in Aging Study (IMIAS) baseline (2012) data. FOF was measured using the Falls Efficacy Scale-International (FES-I). Stepwise linear regression was used to identify factors associated with FOF. RESULTS: A total of 429 participants identified themselves as having heart disease diagnosed by their physician (mean age 69.5 ± 2.9). Older adults with HD reported on average (25.6) higher FOF than those without HD. For older adults with HD, FES-I increased significantly by 1.3, 1.0, and 0.6 points, when the Short Physical Performance Battery, the Leganes Cognitive Test, and QOL total scores decreased by one point. FES-I also significantly increased by 3.2 when income was insufficient compared to sufficient or very sufficient income. DISCUSSION: FOF is multifactorial, and our findings provide a base for developing future management rehabilitation intervention programs aimed at decreasing FOF among older adults with HD.

Precisão da medida de mobilidade no espaço de vida para discriminar fragilidade e sarcopenia em idosos / Accuracy of the life-space mobility measure for discriminating frailty and sarcopenia in older people

Resumo Objetivo Identificar o perfil de mobilidade nos espaços de vida em idosos que vivem na comunidade e estabelecer a precisão dos pontos de corte desse instrumento para discriminar entre níveis de fragilidade, fragilidade em marcha e de risco de sarcopenia. Método Estudo observacional e metodológico com 391 participantes com 72 anos e mais (80,4±4,6), que responderam ao Life Space Assessment (LSA) e a medidas de rastreio de fragilidade e risco de sarcopenia usando respectivamente o fenótipo de fragilidade e o SARC-F. Os pontos de corte para fragilidade e risco de sarcopenia foram determinados por meio da Curva ROC (Receiver Operating Characteristic) com intervalos de confiança de 95%. Resultados A média da pontuação no LSA foi 53,6±21,8. Os pontos de corte de melhor acurácia diagnóstica foram ≤54 pontos para fragilidade em marcha (AUC= 0,645 95%; p<0,001) e ≤60 pontos para risco de sarcopenia (AUC= 0,651 95%; p<0,001). Conclusão A capacidade de idosos de se deslocar nos vários níveis de espaços de vida, avaliado pelo LSA demonstrou ser uma ferramenta viável que pode contribuir no rastreio de fragilidade em marcha e de risco de sarcopenia e, com isso, prevenir desfechos negativos.

Abstract Objective To identify the profile of a sample of older people recruited at home based on a measure of life-space mobility and to establish the accuracy of the cut-off points of this instrument for discriminating between levels of frailty, frailty in walking speed and risk of sarcopenia. Method An observational methodological study of 391 participants aged ≥72 (80.4±4.6) years, who answered the Life-Space Assessment (LSA) and underwent frailty and risk of sarcopenia screening using the frailty phenotype and SARC-F measures, respectively, was performed. The cut-off points for frailty and risk of sarcopenia were determined using ROC (​​Receiver Operating Characteristic) curves and their respective 95% confidence intervals. Results Mean total LSA score was 53.6±21.8. The cut-off points with the best diagnostic accuracy for total LSA were ≤54 points for frailty in walking speed (AUC=0.645 95%; p<0.001) and ≤60 points for risk of sarcopenia (AUC=0.651 95%; p<0.001). Conclusion The ability of older people to move around life-space levels, as assessed by the LSA, proved a promising tool to screen for frailty in walking speed and risk of sarcopenia, thus contributing to the prevention of adverse outcomes.

SPPB as a predictor of functional loss of hospitalized older adults / A SPPB como preditora da perda da capacidade funcional de idosos hospitalizados

Abstract Introduction: Immobility is associated with adverse outcomes such as loss of functional capacity and longer hospitalization. Objective: To assess intra-hospital mobility at admission as a predictor of loss of functional capacity during older adults´ hospitalization. Methods: A prospective cohort study was conducted, and personal and hospital related risk factors were assessed at admission and discharge. To determine whether Short Physical Performance Battery (SPPB) on admission could predict loss of functional capacity during hospitalization, a ROC curve was performed and area under the curve (AUC) was calculated. Binary logistic regression models were used to identify predictors of loss of functional capacity. Model 1 contained only SPPB. Model 2 SPPB was matched with age, sex, instrumental activity of daily living (IADL), cognition, depression and surgery. Data were entered into SPSS version 18.0. Results: 1,191 patients were included with a mean age of 70.02 (± 7.34). SPPB cutoff point of 6.5 (sensitivity 62%, specificity 54%) identified 593 (49.8%) patients at risk for functional loss. In logistic regression, SPPB alone showed prediction of functional loss (p < 0.001, OR 1.8, 95% CI = 1.5-2.5) between admission and discharge. Model 1 explained between 22 to 32% of the variation in functional capacity. In Model 2, three variables contributed to the loss. SPPB 6.5 increased 1.8 times (95% CI = 1.3-2.4), being a woman increased 1.4 times (95% CI = 1.0-1.8) and not having surgery increased 2 times (95% CI = 1.4-2.8) the chance of having functional loss during hospitalization. Conclusion: SPPB is a good instrument to predict loss of functional capacity in hospitalized older adults.

Resumo Introdução: A imobilidade está associada a resultados adversos, como perda da capacidade funcional e maior tempo de hospitalização. Objetivo: Avaliar a mobilidade intra-hospitalar na admissão como preditor de perda da capacidade funcional durante a hospitalização de idosos. Métodos: Um estudo de coorte prospectivo foi conduzido e os fatores de risco pessoais e relacionados ao hospital foram avaliados na admissão e alta. Para determinar se o Short Physical Performance Balance (SPPB) na admissão poderia prever a perda de capacidade funcional durante a internação, uma curva ROC foi realizada e a área sob a curva (AUC) foi calculada. Modelos de regressão logística binária foram usados para identificar preditores de perda de capacidade funcional. O modelo 1 continha apenas SPPB. O modelo 2 SPPB foi pareado com idade, sexo, atividades instrumentais da vida diária (AIVD), cognição, depressão e cirurgia. Os dados foram inseridos no SPSS versão 18.0. Resultados: Foram incluídos 1.191 pacientes com idade média de 70,02 (± 7,34). O ponto de corte do SPPB de 6,5 (sensibilidade 62%, especificidade 54%) identificou 593 (49,8%) pacientes com risco de perda funcional. Na regressão logística, o SPPB sozinho mostrou predição de perda funcional (p < 0,001, OR 1,8, IC 95% = 1,5-2,5) entre a admissão e a alta. O modelo 1 explicou entre 22 a 32% da variação da capacidade funcional. No Modelo 2, três variáveis contribuíram para a perda. SPPB 6,5 aumentou 1,8 vezes (IC 95% = 1,3-2,4), ser mulher aumentou 1,4 vezes (IC 95% = 1,0-1,8) e não ter operado aumentou 2 vezes (IC 95% = 1,4-2,8) a chance de ter perda funcional durante a hospitalização. Conclusão: O SPPB é um bom instrumento para predizer a perda da capacidade funcional em idosos hospitalizados.

Cut-off points to screening for sarcopenia in community-dwelling older people residents in Brazil.

BACKGROUND: At a time when the world's population is aging, one of the most important challenges for the healthcare field is to control the decline of the musculoskeletal system. This decline consists of a reduction in muscle mass and function, which is called sarcopenia and is associated with adverse health outcomes. Although there has been an increase in the number of publications on sarcopenia and its consequences, the reported prevalence varies widely, since these depend on the characteristics of the population studied, the definitions found in the literature and the cut-off points adopted. In this perspective, the heterogeneity in the classification and the different reference values has a critical impact on the epidemiology of sarcopenia, since neither the procedures, the components and the cut-off points are consistent. OBJECTIVES: To develop cut-off points for the screening of sarcopenia in community-dwelling older people residents in the northeast of Brazil and compare the prevalences between the values defined by the consensus and the values of the population studied. METHODS: Community-dwelling older men and women living in three cities in the countryside of Rio Grande do Norte were evaluated. Cutoff points were defined for the variables used to screen for sarcopenia (handgrip strength, SMI, gait speed and SPPB) using the 20th percentile of their population distributions. RESULTS: The sample was composed of 1,290 older people (62.5% female and 37.5% male), with an average of 69.5 (± 6.05) years of age. Regarding the cutoff points, the handgrip values were defined as 25.3 kg and 16 kg for men and women, respectively. Considering the SMM adjusted according to their height, the values of 7.88 kg/m2 were adopted for men and 5.52 kg/m2 for women. When adjusting by BMI we obtained 0.73 kg/BMI for men and 0.41 kg/BMI for women. For gait speed it was defined 0.71 m/s for men and 0.63 m/s for women. In the case of SPPB, the result was the same for both genders (≤8). When applying the values found in the studied population, a variation in prevalence was observed for both men and women, depending on the cut-off points and consensus used. CONCLUSION: The cutoff values found in our population were lower than those adopted by international consensus (EWGSOP2, IWGS and FNIH), except for HGS in woman and SMI/m2 for men. Therefore, using specific cutoff points for different populations can provide an accurate assessment of the presence of sarcopenia and better target health prevention strategies for the older people living in the community.

Relationship between phase angle and physical performance measures in community-dwelling older adults.

INTRODUCTION: The phase angle (PhA) is a measure of great clinical relevance provided through the Bioelectric Impedance Analysis (BIA). PhA is related to health status. Physical performance measures are also similarly associated to the health status of older individuals, however, studies which asses the relationship between these two measures are scarce. OBJECTIVE: To identify the relationship between PhA and physical performance measures in community-dwelling older adults in a Brazilian sample. METHODOLOGY: This was a cross-sectional study in which 200 community-dwelling older adults up to 65 years of age of both genders were recruited. Physical performance was evaluated by walking speed and handgrip strength, and the PhA was derived from BIA. Linear regression models were used to estimate the associations between PhA and physical performance measures. Two models were built: the first model was adjusted by handgrip and walking speed; and the second model additionally included the number of chronic diseases, gender, age and body mass index (BMI). RESULTS: A total of 200 subjects were evaluated through BIA. Men showed a mean age of 72.13 ± 3.42 years and women 71.94 ± 3.35 years. Mean PhA among men was 5.99 ± 0.67, while the mean obtained for women was 5.43 ± 0.70. Linear regression showed that handgrip strength (ß: 0.036; p-value < 0.001; ß: 0.024; p-value: 0.005) and walking speed (ß: 0.495; p-value: 0.044; ß: 0.619, p-value: 0.009) were correlated with the PhA in both models. CONCLUSION: The results of our study revealed that PhA is a good marker of physical performance for the Brazilian community-dwelling older adults studied.
