ABSTRACT
ABSTRACT Frailty and sarcopenia are geriatric syndromes highly prevalent, complex, and hard to diagnose and treat. The literature still lacks a consensus on which resistance training program is better for older people, especially when considering frailty status and sarcopenia. We aimed to evaluate the effectiveness of a progressive resistance training program on muscle mass and frailty status in older sarcopenic women. This study included 18 community-dwelling sarcopenic women aged 65 or older enrolled in the progressive resistance training program. The intervention was based on 75% of each subject's maximum repetition test (3 times/week, for 12 weeks). Before the intervention, 16.7% were frail, and 61.1% were pre-frail; after the intervention, 5.6% were frail, and 50% were pre-frail. The result shows that the intervention reduced frailty status and increased muscle mass (p=0.01). Hence, after the intervention, we observed both a decrease in frailty and a positive change in function, since the percentage of robust women increased twice (p=0.01). We conclude that the progressive resistance training program might be the best strategy to prevent frailty and sarcopenia. Therefore, we suggest using weight resistance training in daily clinical practice to improve muscle mass and decrease frailty status in sarcopenic women.
RESUMO Fragilidade e sarcopenia são consideradas síndromes geriátricas que apresentam grande prevalência e complexidade e são de difícil diagnóstico e tratamento. Ainda não existe consenso quanto ao melhor programa de exercícios resistidos, especialmente quando se considera a fragilidade e a sarcopenia. O objetivo deste estudo foi avaliar a efetividade de um programa de carga na massa muscular e na classificação de fragilidade em idosas sarcopênicas. Participaram 18 idosas sarcopênicas, com idade a partir de 65 anos, que completaram um programa de carga progressiva. A intervenção utilizou o cálculo de 75% de uma repetição máxima (1RM) para cada participante (3 vezes/semana, por 12 semanas). Antes da intervenção, 16,7% foram consideradas frágeis e 61,1% pré-frágeis; após, 5,6% passaram a ser consideradas frágeis e 50% pré-frágeis. Os resultados mostraram que a intervenção alterou a classificação de fragilidade e aumentou a massa muscular das idosas (p=0,01). Observou-se diminuição nos itens de classificação da fragilidade e consequente melhora no perfil funcional, havendo o aumento da porcentagem daquelas consideradas não frágeis após a intervenção (p=0,01). Conclui-se que o programa de exercício resistido progressivo é provavelmente uma das melhores estratégias para prevenir a fragilidade e a sarcopenia. Desta forma, recomenda-se o seu uso na prática clínica diária para melhorar a massa muscular e diminuir o status de fragilidade em mulheres sarcopênicas.
RESUMEN La fragilidad y la sarcopenia son síndromes geriátricos de alta prevalencia y complejidad, además de ser de difícil diagnóstico y tratamiento. Todavía no hay un consenso sobre el programa de ejercicios de fuerza más indicado, especialmente teniendo en cuenta la fragilidad y la sarcopenia. El objetivo de este estudio fue evaluar la efectividad de un programa de carga sobre la masa muscular y la clasificación de la fragilidad en ancianas con sarcopenia. Participaron 18 ancianas con sarcopenia, de más de 65 años y que completaron un programa de carga progresiva. La intervención utilizó el cálculo del 75% de repetición máxima (1RM) para cada participante (3 veces/semana, durante 12 semanas). Antes de la intervención, el 16,7% de las participantes se consideraban frágiles y el 61,1% prefrágiles; después de la intervención, el 5,6% se consideraban frágiles y el 50% prefrágiles. Los resultados mostraron que la intervención produjo cambios en la clasificación de la fragilidad y aumentó la masa muscular de las ancianas (p=0,01). Hubo una reducción en los ítems de clasificación de la fragilidad y una mejora en el perfil funcional, con un aumento del porcentaje de aquellas consideradas no frágiles después de la intervención (p=0,01). Se concluye que el programa de ejercicios de fuerza progresiva se mostró una de las mejores estrategias para prevenir la fragilidad y la sarcopenia. Por tanto, se recomienda aplicarlo en la práctica clínica cotidiana para mejorar la masa muscular y disminuir el estado de fragilidad de mujeres con sarcopenia.
ABSTRACT
A cross-sectional study was conducted to compare the habitual physical activity level, measured by accelerometry, gait performance, assessed by the GAITRite® system, handgrip strength, and static balance between older Brazilian women who participate (n = 50; 70.7 ± 5.5 years) and do not participate (n = 50; 70.1 ± 5.6 years) in a regular physical exercise program, and to investigate whether participation in a regular exercise program ensures compliance with physical activity recommendations. Older women who participated in a regular physical exercise program had significantly shorter sedentary activity time (effect size [ES] = 0.54), longer moderate activity time (ES = 0.85), and higher energy expenditure (ES = 0.64), number of steps (ES = 0.82), gait speed (ES = 0.49), and step length (ES = 0.45). However, regular participation in an exercise program did not guarantee compliance with physical activity recommendations. Behavioral changes to increase physical activity levels among older women who do and do not participate in a regular exercise program are necessary.

BACKGROUND: Psychosocial factors have been identified as important predictors of onset, course and persistence of low back pain (LBP) in the general population. OBJECTIVE: To identify factors associated with attitudes/beliefs in older adults with LBP throughout a 12-month follow-up. METHODS: A longitudinal investigation was conducted with 500 participants aged ≥60 years reporting a new (acute) episode of nonspecific LBP. Data were obtained at baseline, 6-week, 3-, 6-, 9-, and 12-month interviews. The study variables were: [dependent] LBP-related attitudes/beliefs that were assessed by the Back Beliefs Questionnaire (BBQ); [independent] age; sex; LBP intensity 'at-the-present-time' of interview and 'over-the-past-week' before interview; LBP frequency; LBP-related treatments; disability; mobility; depressive symptoms; self-perceived recovery; expectation of pain improvement; and expectation for returning to activities. Data were analysed by multiple linear regression analysis. RESULTS: At baseline, 85.7% of the participants were female, had mean age of 69.0 (6.3) years, mean BBQ score of 24.5 (6.5), and 79.6% reported pain complaints after an acute episode of LBP. After 12 months, participants maintained a mean BBQ score of 24.6 (6.6) and 63.3% still reported pain complaints after an acute episode of LBP at baseline. Multivariate analysis showed that disability, advancing age, poor expectation of pain improvement in 3 months, and mobility decline were significantly associated with worse BBQ scores during all follow-ups. CONCLUSION: Ageing, hopelessness, and physical and functional impairment impact pain-related behaviours among older patients seeking healthcare due to acute LBP complaints. Their screening may assist in strategies to manage symptoms and prevent the persistence of pain.

BACKGROUND: Low back pain (LBP) has emerging as an epidemic, multifactorial and multidimensional condition in older age. Assessment of attitudes and beliefs of patients with back pain is necessary for understanding the impact of psychosocial factors on pain perception and management. OBJECTIVES: To cross-culturally adapt and examine the validity and reproducibility (intra and interrater reliability and agreement) of the Back Beliefs Questionnaire (BBQ) in older Brazilians with acute LBP. DESIGN AND SETTING: Cross-sectional methodological report conducted at the Department of Physical Therapy of the Universidade Federal de Minas Gerais, Belo Horizonte, Brazil. METHODS: The present study was conducted for translating, adapting, and examining the psychometric properties of a questionnaire. Participants aged ≥ 60 years experiencing an acute episode of LBP were recruited. Coefficients of internal consistency, reliability and agreement were obtained using Cronbach's α, intraclass correlations, and standard error of measurement and the smallest detectable change, respectively. RESULTS: Twenty-six participants aged between 60-84 years and reporting a mean of 9.8 (4.3) years of schooling completed the study. The Brazilian Portuguese-language version of the BBQ (BBQ-Brazil) was proposed and presented with adequate conceptual, semantic, operational, and measurement equivalence from the original version. Intra and interrater evaluations showed moderate (0.74) and excellent (0.91) intraclass correlation coefficients, respectively, with small standard error of measurement for both evaluations. Internal consistency was considered adequate (0.70). CONCLUSION: BBQ-Brazil had consistent measurements of validity and reproducibility, and proved to be a valuable tool in clinical practice for addressing attitudes and beliefs of older patients with acute LBP.

RESUMO A velocidade da marcha (VM) tem sido considerada um marcador de saúde em idosos capaz de predizer desfechos adversos de saúde, mas a compreensão de fatores associados a ela ainda é limitada e controversa. O objetivo deste trabalho é identificar desfechos adversos de saúde relacionados ao declínio da velocidade de marcha em idosos comunitários. Trata-se de estudo transversal e multicêntrico, que avaliou o autorrelato de doenças crônicas e de hospitalização no último ano, polifarmácia e velocidade de marcha. Utilizou-se análise de regressão logística para estimar os efeitos de cada variável independente na chance de os idosos apresentarem declínio na velocidade de marcha inferior (VM<0,8m/s) (α=0,05). Participaram da pesquisa 5.501 idosos. A menor velocidade da marcha mostrou-se associada a portadores de doenças cardíacas (OR=2,06; IC: 1,67-2,54), respiratórias (OR=3,25; IC: 2,02-5,29), reumáticas (OR=2,16; IC: 1,79-2,52) e/ou depressão (OR=2,51; IC: 2,10-3,14), hospitalizados no último ano (OR=1,51; IC: 1,21-1,85) e polifarmácia (OR=2,14; IC: 1,80-2,54). Assim, os resultados indicaram que idosos com velocidade de marcha menor que 0,8m/s apresentam maior risco de eventos adversos de saúde. Dessa forma, sugere-se que a velocidade de marcha não seja negligenciada na avaliação de idosos comunitários, inclusive na atenção básica.
RESUMEN La velocidad de la marcha (VM) se ha considerado un marcador de salud en los ancianos capaz de predecir resultados adversos en la salud, pero la comprensión de sus factores asociados todavía es limitada y controvertida. El presente estudio tiene como objetivo identificar los resultados adversos para la salud relacionados con la disminución de la velocidad de la marcha en los ancianos comunitarios. Se trata de un estudio transversal y multicéntrico, el que evaluó el autoinforme de enfermedades crónicas y de la hospitalización en el último año, la polifarmacia y la velocidad de la marcha. Se utilizó el análisis de regresión logística para estimar los efectos de cada variable independiente sobre la posibilidad de que los ancianos presenten una disminución más baja en la velocidad de la marcha (VM<0,8 m/s) (α=0,05). Participaron en el estudio 5.501 ancianos. La velocidad de marcha más baja estuvo asociada a portadores de enfermedades cardíacas (OR=2,06; IC: 1,67-2,54), respiratorias (OR=3,25; IC: 2,02-5,29), reumáticas (OR=2,16; IC: 1,79-2,52) y/o depresión (OR=2,51; IC: 2,10-3,14), hospitalizados en el último año (OR=1,51; IC: 1,21-1,85) y polifarmacia (OR=2,14; IC: 1,80-2,54). De esta manera, los resultados indicaron que los ancianos con velocidades de marcha por debajo de 0,8m/s presentan un mayor riesgo de eventos adversos para la salud. Por lo tanto, se sugiere que la velocidad de la marcha no debe ser descuidada en la evaluación de ancianos comunitarios, incluso en la atención primaria.
Abstract Gait speed (GS) can predict adverse health outcomes. However, an understanding of its associated factors is still limited and with some controversy. The objective of this study was to identify adverse health outcomes related to the decline in gait speed in community-dwelling older adults. This is a cross-sectional study that evaluated records of chronic diseases and hospitalization in the last year, polypharmacy, and gait speed. Logistic regression analysis was used to estimate the effects of each independent variable on the chance of older adults presenting a decline in gait speed (GS<0.8 m/s) (α=5%). In total, 5,501 older adults participated. Brazilian older adults with heart diseases (OR=2.06; 1.67-2.54 CI), respiratory diseases (OR=3.25; 2.02-5.29 CI), rheumatic (OR=2.16; 1.79-2.52 CI) and/ or depression diseases (OR=2.51; 2.10-3.14 CI); hospitalized in the last year (OR=1.51; 1.21-1.85 CI) and under polypharmacy (OR=2.14; 1.80-2.54 CI) were associated with lower gait speed. Thus, the results showed that those with gait speed lower than 0.8 m/s are at higher risk of some adverse health events. Therefore, it is suggested that gait speed should not be neglected in the evaluation in community-dwelling older adults, including basic health care.

ABSTRACT The mini-mental state examination (MMSE) is a screening test used worldwide for identifying changes in the scope of cognition. Studies have shown the influence of education, age and sex in the MMSE score. However, in Brazil, the studies consider only one factor to score it. The aim of this study was to establish a prediction equation for the MMSE. An exploratory cross-sectional study was developed and trained researchers examined participants at the community. The volunteers were evaluated by the MMSE and also by the Geriatric Depression Scale (GDS). The MMSE score was the dependent variable. Age, educational level, sex, and GDS score were the independent variables. Multivariate regression analysis was used to determine the model of best prediction value for MMSE scores. A total of 250 participants aged 20-99 years, without cognitive impairment, were assessed. The educational level, age, and sex explained 38% of the total variance of the MMSE score (p<0.0001) and resulted in the following equation: MMSE=23.350+0.265(years of schooling)-0.042(age)+1.323(sex), in which female=1 and male=2. The MMSE scores can be better explained and predicted when educational level, age, and sex are considered. These results enhance the knowledge regarding the variables that influence the MMSE score, as well as provide a way to consider all of them in the test score, providing a better screening of these patients.
RESUMO O mini-exame do estado mental (MEEM) é um teste de rastreio mundialmente utilizado para identificar alterações no âmbito da cognição. Estudos têm demonstrado a influência da educação, idade e gênero na pontuação do MEEM. No entanto, no Brasil, os estudos consideram apenas um fator para a pontuação no teste. O objetivo do estudo foi estabelecer uma equação preditiva para o MEEM. Um estudo transversal exploratório foi desenvolvido e examinadores treinados avaliaram participantes da comunidade. Os voluntários foram avaliados pelo MEEM e pela Escala de Depressão Geriátrica (EDG). A pontuação do MEEM foi a variável dependente. A idade, nível educacional, gênero e pontuação na EDG foram as variáveis independentes. A análise de regressão multivariada foi utilizada para determinar o modelo de melhor valor preditivo para os escores do MEEM. Foram avaliados 250 indivíduos entre 20 e 99 anos, sem comprometimento cognitivo. O nível educacional, a idade e o sexo explicaram 38% da variância total da pontuação do MEEM (p<0,0001) e resultaram na equação: MEEM=23,350+0,265(anos de escolaridade)-0,042(idade)+1,323(gênero), em que mulher=1 e homem=2. A pontuação do MEEM pode ser melhor explicada e predita quando o nível educacional, idade e gênero são considerados. Os resultados contribuem para o conhecimento sobre as variáveis que influenciam o escore do MEEM, bem como fornece uma maneira de considerá-las na pontuação do teste, proporcionando uma melhor triagem desses pacientes.

BACKGROUND AND PURPOSE: Frailty is a common and important geriatric syndrome, distinct from any single chronic disease, and an independent predictor of mortality. It is characterized by age-associated decline in physiological reserve and function across multiple systems, culminating in a vicious cycle of altered energy expenditure. The total energy expenditure (TEE) of an individual includes the resting metabolic rate (RMR), the thermic effect of feeding, and the energy expenditure in physical activity (PAEE). The investigation of the energy expenditure of older adults who are frail is essential for better understanding the syndrome. Therefore, we compared the RMR, the PAEE, the physical activity level (PAL), and the TEE of older adults who were frail with those who were not frail. METHODS: A cross-sectional study was conducted with 26 community-dwelling older adults (66-86 years of age). Older adults in the frail and nonfrail groups were matched for age and gender, and the matched pairs were randomly selected to continue the study. The RMR was measured by indirect calorimetry. The TEE was obtained by the multipoint, doubly labeled water method. After collecting a baseline urine sample, each participant received an oral dose of doubly labeled water composed of deuterium oxide and oxygen-18 (H2O). Subsequently, urine samples were collected on the 1st, 2nd, 3rd, 7th, 12th, 13th, and 14th days after the baseline collection and analyzed by mass spectrometry. RESULTS AND DISCUSSION: The older adults who were frail presented significantly lower PAEE (1453.7 [1561.9] vs 3336.1 [1829.3] kj/d, P < .01), PAL (1.4 [0.3] vs 1.9 [0.6], P = .04), and TEE (7919.0 [2151.9] vs 10442.4 [2148.0] kj/d, P < .01) than the older adults who were nonfrail. There was no difference in their RMRs (5673.3 [1569.2] vs 6062.0 [1891.7] kj/d, P = .57). Frailty has been associated with a smaller lean body mass and with a disease-related hypermetabolic state, which might explain the lack of difference in the RMR. The PAL of the older adults who were frail was below the recommended level for older adults and determined a lower PAEE and TEE when compared with older adults who were not frail. CONCLUSION: This study showed that low energy expenditure in physical activity is a main component of frailty. The PAL of the older adults who were frail was far below the recommended level for older adults.

Alteração cognitiva e fragilidade são frequentemente encontradas em idosos e parece haver uma relação entre elas. Entretanto, pouco se sabe sobre a prevalência e a transição para a fragilidade nos idosos com alteração cognitiva, principalmente para a população brasileira. O objetivo do estudo foi avaliar a prevalência e a transição entre os estados de fragilidade em um grupo de idosos com alteração cognitiva em uma coorte prospectiva de um ano. Neste estudo de coorte foram avaliados 59 idosos comunitários com alteração cognitiva (≥ 65 anos). O indivíduo frágil foi identificado por apresentar pelo menos três dos seguintes critérios: perda de peso não intencional, fraqueza da força de preensão palmar, exaustão, lentidão na marcha e baixo nível de atividade física. Quando o indivíduo apresentou um ou dois critérios, foi considerado pré-frágil; quando não apresentou nenhum critério, foi considerado não frágil. A função cognitiva foi avaliada pelo Mini Exame do Estado Mental e a gravidade, pela Clinical Dementia Rating Scale. Do total de 59 idosos avaliados na linha de base, 28 (47,5%) eram frágeis, a mesma quantidade era de pré-frágeis e apenas 3 idosos eram não frágeis. Em 12 meses, verificou-se uma transição para fragilidade de 33,3%. Este estudo mostrou que a prevalência de fragilidade é alta entre os idosos com alteração cognitiva e, em um período de 12 meses, novos casos de fragilidade ocorreram entre os idosos com alteração cognitiva. Entretanto, mais estudos são necessários para investigar com melhor precisão uma relação existente entre o declínio cognitivo e a fragilidade
Cognitive impairment and frailty are often found in older people, and they appear to be related to each other. However, little is known about the prevalence and transition to frailty in older adults with cognitive impairment, especially in the Brazilian population. The present study aimed to determine the prevalence and transitions between frailty states in a cohort of older adults with cognitive impairment followed prospectively for 1 year. A cohort of 59 community-dwelling older adults (aged ≥ 65 years) with cognitive impairment was evaluated. Individuals were classified as frail by the presence of 3 or more of the following criteria: unintentional weight loss; reduced grip strength; exhaustion; slowness; and low physical activity level. Individuals meeting 1 or 2 criteria were classified as prefrail, and those meeting 0 criteria as nonfrail. Cognitive function was assessed by the Mini-Mental State Examination, and severity, by the Clinical Dementia Rating scale. Of 59 older adults evaluated at baseline, 28 (47.5%) were classified as frail, 28 (47.5%) as prefrail, and only 3 (5%) as nonfrail. Over 12 months, 33.3% of participants transitioned from prefrail to frail. The present study showed a high prevalence of frailty in older adults with cognitive impairment and, within 12 months, new cases of frailty were identified in this population. Therefore, more research is needed to further investigate the relationship between cognitive decline and frailty.

RESUMO Estabeleceram-se pontos de corte alternativos para o cálculo da massa muscular apendicular (MMA) em idosos brasileiros para classificar a sarcopenia. Foram analisados dados de 562 idosos participantes do estudo Fibra (Fragilidade em Idosos Brasileiros), no polo Belo Horizonte. Por meio da equação de Lee, determinaram-se pontos de corte para MMA baseado na percentil 20 de sua distribuição na população estudada. Em seguida, os sujeitos foram classificados para sarcopenia de acordo com os critérios do Consenso Europeu sobre Definição e Diagnóstico da Sarcopenia em Idosos, além de avaliadas as possíveis associações desta com a capacidade funcional e comorbidades. A maioria da amostra foi composta por mulheres (65,5%) com idade média de 74,1 (±6,4) e média de 1,5 (±1,4) comorbidades. Os pontos de corte para MMA foram <6.47kg/m2 para mulheres e <8.76kg/m2 para homens. A prevalência de sarcopenia foi de 14,9%, sendo 13,5% da população parcialmente dependente para atividades básicas de vida diária (ABVD), 30,6% para atividades instrumentais de vida diária (AIVD) e 66,7% para atividades avançadas de aida diária (AAVD). A sarcopenia se correlacionou apenas com AIVD (r=0,081, p= 0.05), e encontrou-se uma correlação negativa entre sarcopenia e comorbidades (r= −0,103, p=0,014). Foram propostos pontos de corte específicos para MMA para a população de idosos brasileiros e não foram encontradas correlações entre as variáveis do estudo, exceto para AIVD e comorbidades.

ABSTRACT Alternative cut-off points for the calculation of appendicular muscle mass (AMM) in older Brazilians were established to classify sarcopenia. Data from 562 older adults from Belo Horizonte who participated in the Fibra study (Fragilidade em Idosos Brasileiros [Fragility in Older Brazilians) were analyzed. Through Lee's equation, cut-off points for AMM were determined based on the 20th percentile of their distribution in the studied population. Then, the subjects were classified for sarcopenia according to the criteria of the European Consensus on Definition and Diagnosis of Sarcopenia in Older Adults, and its possible associations with functional capacity and comorbidities were evaluated. Most of the sample was composed by women (65.5%) with 74.1 years of age (±6.4) and 1.5 (±1.4) comorbidities on average. The cut-off points for AMM were <6.47kg/m2 for women and <8.76kg/m2 for men. The prevalence of sarcopenia was 14.9%, 13.5% of the population being partially dependent for basic activities of daily living (BADL), 30.6% for instrumental activities of daily living (IADL) and 66.7% for advanced activities of daily living (AADL). Sarcopenia was correlated with IADL only (r=0.081, p=0.05), and a negative correlation was found between sarcopenia and comorbidities (r=−0.103, p=0.014). Cut-off points specific to AAM for the population of older Brazilians were proposed, and no correlations between the variables of the study were found, except for IADL and comorbidities.
ABSTRACT
Abstract Objective :To seek an understanding of how frail elderly persons construct resilience. Method: The "signs, meanings and actions" model was used. The population was randomly selected among elderly persons classified as robust or pre-frail in the FIBRA-study, Belo Horizonte, Minas Gerais, Brazil. Thirteen elderly persons (aged 69 to 86) were interviewed. Results: a) the construction of bonds - a healthy relationship with spouses, sons, daughters, grandchildren and great-grandchildren brings meaning to and sustains life and contributes to its organization; b) the reinvention of oneself - when suffering trauma, elderly people seek paths that can give sense to life, even if difficult memories persist; c) religiosity: catholic, evangelical or spiritualist experiences strengthen; cures, protections and so-called miracles are valued, and the religious community represents a space for belonging. Conclusion: Resilience is constructed through the bonds between the elderly person and those close to them, and in the search for solutions, including through the religious experience.
Resumo Objetivo: Buscar uma compreensão, a partir da visão de idosos em processo de fragilização, sobre como tecem sua resiliência. Método: Foram entrevistados 13 idosos (69 a 86 anos), selecionados aleatoriamente entre idosos classificados como robustos ou pré-frágeis em Belo Horizonte, Minas Gerais, Brasil, na Rede FIBRA. A coleta e a análise dos dados foram fundamentadas no modelo de "Signos, significados e ações". Resultados: a) Construção de vínculos - a relação saudável com os cônjuges, filhos, netos e bisnetos traz sentido à vida, sustenta e se torna um organizador; b) reinvenção de si mesmo - ao sofrer um trauma, uma parte da pessoa busca caminhos que possam dar sentido à vida, mesmo se persistem as memórias sofridas; c) a religiosidade - católica, evangélica ou espírita - fortalece para trabalhar na solução de problemas e aceitar o imutável: valorizam-se curas, proteções, milagres e a comunidade religiosa como espaço de pertença. Conclusão: Os idosos constroem resiliência na sua ligação com as pessoas próximas, na busca de soluções, e na experiência religiosa.

ABSTRACT Introduction: Accurate measures of physical activity to establish dose-response relationship in health outcomes are still controversial. Scales that estimate caloric expenditure are proposed with a view to categorizing the phenomenon globally. Objective: To carry out a factor analysis of the structure of the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese, and propose a new adapted version for the Brazilian elderly community. Methods: Participants were elderly female members of the community, without any distinction in terms of ethnic group and/or social class, who frequented extension projects of two higher education institutions. Those with cognitive impairments; dependence on walking aids; musculoskeletal pain in the last two weeks and neurological diseases were excluded from the study. All participants answered the questionnaire with sociodemographic and clinical data and the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese version. We determined whether each activity had been undertaken by the participants and the average number of times it was performed over the last two weeks, considering average time, in minutes, on each occasion. Each activity was considered a single item and energy expenditure was calculated according to the authors' instructions. We used factor analysis with Varimax orthogonal rotation, excluding items whose variance was equal to zero. Correlation between items was determined using the Pearson correlation matrix. Internal consistency between items, before and after the factor analysis, was verified using Cronbach's α coefficient. 5% significance level. Results: Participants were 220 women (70.8 ± 5.9 years). The factor analysis resulted in 10 components, which explained, in total, 61.87% of the variance of the total score on the scale. Each component was composed of one, two or three aggregate items. Internal consistency by Cronbach's α coefficient was 0.30. Conclusion: The factor analysis of the structure of the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese- has shown a new range with 10 components, which explained, in total, more than 60% of the variance of the total score on the scale, yet with low internal consistency. Level of Evidence III; Study of nonconsecutive patients; without consistently applied reference ''gold'' standard.

ABSTRACT
Objective: To understand how elderly persons perceive subjective aspects linked to current and other life experiences related to the process of becoming frail. Method: A qualitative study, anchored in interpretative anthropology, was performed. The elderly were selected from the FIBRA Network database from those classified as robust or pre-frail, according to the frailty phenotype of Fried et al., in Belo Horizonte, Minas Gerais, Brazil in 2009. We interviewed 15 elderly people of different genders, ages, income, religion and functional status, in 2016. In data collection and analysis, the "signs, meanings and actions" analysis model was used, which allows the understanding of the elements that are significant for a population to read a given situation and to position themselves in relation to it. Results: From the analysis the following categories emerged: a) suffering throughout life and b) suffering and the resources to deal with them. Conclusion: The interviewees described sufferings of different aspects that constitute their life, from birth to aging, according to experiences related to pain, loss and learning. The perception of current frailty refers to their life history, marked by physical or mental suffering, whether insidious or temporary - as well as illnesses, how they manifest themselves today, and a lack of financial resources and urban security. The narratives bring us closer to the perception of frailty as being constitutive of human beings, who can easily break.
Objetivo: Compreender como a pessoa idosa percebe aspectos subjetivos ligados a sofrimentos atuais e outros experimentados ao longo da vida e que se remetem ao processo de fragilização. Método: Estudo qualitativo, ancorado na Antropologia interpretativa. Foram selecionados idosos participantes no banco de dados da Rede FIBRA - entre aqueles classificados como robustos ou pré-frágeis em 2009, no polo Belo Horizonte, Minas Gerais, Brasil, segundo o referencial do fenótipo de fragilidade de Fried et al. Foram entrevistados 15 idosos, de diferentes sexos, idades, renda, religião, condição funcional. Foi utilizado o modelo de análise "Signos, significados e ações que possibilitam a compreensão dos elementos significativos para uma população ler uma determinada situação e se posicionar diante dela". Resultados: Da análise emergiram as categorias: a) o sofrimento ao longo da vida e b) adoecimentos e os recursos para lidar com eles. Conclusão: Os entrevistados narram sofrimentos de diferentes aspectos que constituem a sua vida, do nascer ao envelhecer, conforme experiências que significam dores, perdas, aprendizado. A percepção de fragilização atual remete à história de vida marcada por sofrimentos físicos e/ou mentais, insidiosos ou pontuais - bem como aos adoecimentos, como se manifestam hoje, e à falta de recursos financeiros e de segurança urbana. As narrativas nos aproximam da percepção da fragilidade como sendo constitutiva do ser humano - que pode facilmente trincar.

Abstract Introduction: Resistance training is quoted as one of the best pathways to manage sarcopenia and progressive resistance training is supposed to improve muscle mass, strength and performance in older adults. Objective: The aim was to examine the impact of a progressive resistance exercise program (PREP) on muscle and function performance in sarcopenic community-dwelling elder women. Methods: Quasi-experimental study (pre - post intervention). Participated 18 sarcopenic community-dwelling elder women (65 years or older). PREP based on 75% of the participant's maximum load (12/wk, 3 times/wk). Main outcome measures: muscle strength of knee extensors (isokinetic dynamometry), muscle mass (dual-x ray absorptiometry - DXA), functional performance (Short Physical Performance Battery - SPPB). Paired t-test was used to evaluate differences pre and post intervention. Results: Improvements on power (p = 0.01) and peak torque (p = 0.01) were observed when measured by the isokinetic dynamometer at low speed (60º/s). Improvements on DXA (pre PREP: 5.49 kg/m2 vs. post PREP: 6.01 kg/m2; p = 0.03) and SPPB scores (pre PREP: 9.06 vs. post PREP: 10.28; p = 0.01) were also observed. Conclusion: The PREP was able to improve muscle and functional performance in sarcopenic community-dwelling elder women. This program should be considered in clinical practice.

OBJECTIVE: This study aimed to determine the sociodemographic and health factors that influence older adults who continue to participate in the workforce. METHODS: Data were collected and evaluated for 1762 older adults aged 65 years and older who were living in the community and were enrolled in a population-based study (FIBRA Network Study). Older adults who participated in the workforce were compared with those who did not in terms of sociodemographic characteristics, physical and mental health, and physical functioning and performance in advanced and instrumental activities characteristic of daily living. A multivariate hierarchical logistic regression analysis was performed. RESULTS: Factors associated with not participating in the workforce were aged (OR: 1.71, [95% CI: 1.26-2.30], p<0.001), female gender (OR: 1.70, [95% CI: 1.22-2.37], p=0.002), poor visual perception (OR: 1.31, [95% CI: 1.00-1.72], p=0.046), using 4 or more medications regularly (OR: 1.41, [95% CI: 1.489-2.247], p=0.034), having 3 or more comorbidities (OR: 1.44, [95% CI: 1.01-2.04], p=0.040), and a handgrip strength below 24.6kg/f (18.1-24.6kg/f (2nd tertile): OR: 1.52, [95% CI: 1.06-2.18], p=0.022; 0-18kg/f (1st tertile): OR: 1.60, [95% CI: 1.08-2.38], p=0.019). The probability estimates of the final model explained 67.9% of the events related to not participating in the workforce, as observed by the area under the ROC curve. CONCLUSION: Our results highlight that work in later life is influenced by sociodemographic characteristics, intrinsic capacity, and multimorbidity. We suggest that strategies for optimizing healthy and active aging may help older people to continue participating in the workforce and contributing toward their communities.

OBJECTIVE: To determine the association between body composition and frailty in older Brazilian subjects. MATERIAL AND METHODS: This is a Cross-sectional study called FIBRA-BR and developed in community Brazilian aged ≥65 (n=5638). Frailty was assessed according to Fried et al. definition and body composition was determined by BMI, waist circumference and waist-hip ratio. RESULTS: The lowest prevalence of frailty was observed in subjects with BMI between 25.0 and 29.9kg/m2. Subjects with a BMI <18.5 and those with elevated WC presented a higher risk of frailty compared to eutrophic subjects (odds ratio (OR)=3.10; 95% CI: 2.06-4.67) and (OR=1.15; 95% CI: 1.03-1.27), respectively. Being overweight was protective for pre-frailty (OR=0.48; 95% CI: 0.4-0.58) and frailty (OR=0.77; 95% CI: 0.67-0.9). Obese older people presented a higher risk of pre-frailty only (OR=1.29; 95% CI: 1.09-1.51). Older people with high WC showed a greater proportion of frailty regardless of the BMI range. CONCLUSION: Undernutrition is associated with pre-frailty and frailty in Brazilian elderly subjects, whereas obesity is associated only with pre-frailty. Overweight seems to have a protective effect against the syndrome. The excess of abdominal fat is associated with both profiles independent of the BMI.

ABSTRACT Introduction: Physical activity is an important parameter to be quantified in the elderly. Reliable measurement instruments are needed to evaluate, and design effective therapeutic intervention targets and to monitor patient outcomes. Objective: To adapt cross-culturally and determine the test-retest and inter-rater reliability of the Active Australia Questionnaire in community elders. Methods: A cross-cultural adaptation was performed according to the criteria proposed by Guillemin and Beaton, namely, translation, back-translation, synthesis of translations, submission to the expert committee and implementation of the pre-final version to test the questionnaire. For test-retest reliability, a four-hour interval was given for collection, and a six-hour interval for inter-rater analysis, following the retest. Physical activity information was considered in the last seven days. The characterization of the sample was done by descriptive analysis. For the analysis of reliability we used the intraclass correlation coefficient (ICC). The study included 22 elderly (72.5 ± 5.3 years) and 7.6 ± 3.9 years of education. Results: Test-retest reliability was ICC = 0.97 and the inter-rater reliability was ICC= 0.82. Conclusion: The instrument was semantically and linguistically adequate and reliable to evaluate the level of physical activity in the elderly in the community.

ABSTRACT
PURPOSE: This study aimed to investigate the associated factors with fear of falling in community-dwelling older adults with and without diabetes mellitus. METHODS: Data from the Frailty in Brazilian Older People Study (FIBRA-BR), involving 4449 individuals aged 65years or older (19.2% with diabetes), were analyzed. The potential factors associated with fear of falling included sociodemographic data, chronic diseases, health-related variables and functional capacity measures. Logistic regression analysis was performed to identify the factors associated with fear of falling. RESULTS: Female gender, arthritis or rheumatism, negative health self-perception, frailty, lower Lawton Scale score and reduced gait speed were independently associated with fear of falling in both groups. Factors associated with fear of falling specific to non-diabetic older adults were depression, visual impairment, falls in the previous 12months, obesity, depressive symptoms, higher Katz Index score and decreased handgrip strength. Lower Mini-Mental State Examination score was an associated factor with fear of falling only in those with diabetes. CONCLUSION: The factors associated with fear of falling did differ between non-diabetic and diabetic older adults. Health care professionals should consider such differences when planning their therapeutic approaches for a successful management of fear of falling in these older populations.

BACKGROUND AND PURPOSE: The gait, mobility and lower-limb strength alterations of diabetic elderly women without symptoms of diabetic neuropathy in different periods of the chronic disease can contribute to an early functional diagnosis, allowing prevention of adverse outcomes like falls and disability. This could also contribute to the development of interventions, cures and physiotherapy practice for this population. The aim of this study was to verify the impact of type-2 diabetes mellitus time since diagnosis on gait and functional status of elderly women. METHODS: Eighty-two diabetic elderly women without neuropathic symptoms participated and divided in two groups: 1) 49 elderly (71.4 ± 4.8 years) with less than 10 years of type-2 diabetes mellitus diagnosis, and 2) 33 elderly (70 ± 4.5 years) with 10 or more years of type-2 diabetes mellitus diagnosis. Outcomes were spatiotemporal gait parameters (speed, cadence, step length, base of support, stance time, swing time, and double support time) assessed through GAITRite® system, and functional status assessed using the Timed Up and Go test and five times sit-to-stand test. To compare spatiotemporal gait variables and performance on functional tests between groups, multivariate analysis of variance and Mann-Whitney test were performed, respectively. RESULTS: The group with 10 or more years of diagnosis showed lower gait speed and smaller step length (112.3 cm/s; 59.2 cm) compared with the group with less than 10 years of diagnosis (122.9 cm/s; 62.4 cm). In relation to Timed Up and Go test and five times sit-to-stand test, there were no statistically significant differences between the groups. CONCLUSION: Type-2 diabetes mellitus time since diagnosis has a negative impact on gait speed and step length, but not on functional status of the elderly women.

AIM: Sarcopenia is the age-related loss of muscle mass and function that evolves into disability, loss of independence and death. In Brazil the number of older people is rapidly growing, resulting in an increased prevalence of chronic conditions associated with old age. As prevalence estimates provide essential information to policymakers when developing healthcare strategies, this systematic review and meta-analysis aimed to estimate the prevalence of sarcopenia in older Brazilians. METHODS: Electronic database searches and hand-searching in relevant journals and reference lists were carried out without language restriction. Studies that reported the prevalence of sarcopenia in Brazilians aged 60 years or older were considered for inclusion. Sarcopenia was defined as low muscle mass, low muscle function or low muscle mass and function. Meta-analysis was carried out using a random-effects model. RESULTS: A total of 31 studies were included pooling 9416 participants. The overall prevalence of sarcopenia in older Brazilians was 17.0% (95% CI 13.0-22.0). Sensitivity analysis showed rates of 20.0% (95% CI 11.0-32.0) in women and 12.0% (95% CI 9.0-16.0) in men. Prevalence was 16.0% (95% CI 12.0-23.0) based on low muscle mass and function; and 17.0% (95% CI 9.0-31.0) based only on low muscle mass. The difference between these two criteria was not significant (P = 0.96). CONCLUSIONS: Sarcopenia is an emerging public health issue in Brazil. Attention should be paid to changes in prevalence rates over the next years because of the increase in the older population. Geriatr Gerontol Int 2017; 17: 5-16.

Abstract Introduction: Sarcopenic obesity in older adults may lead to an inability to use muscles efficiently and has been associated with functional deficits and disabilities. Objective: To identify the prevalence of obesity and sarcopenic obesity (SO) among community-dwelling older adults, and to characterize associated sociodemographics, health conditions and functional performance. Methods: Study data are from the FIBRA Network database of the Federal University of Minas Gerais. There were 1,373 older adult participants, subdivided into three groups: 1) non-obese; 2) non-sarcopenic obese; and 3) sarcopenic obese (SO). The latter is defined as a BMI ≥30 kg/m2 and weak palmar grip strength (PGS). Results: The overall prevalence of obesity and SO among older adults was 25.85% and 4.44%, respectively, with levels of frailty and pre-frailty among at 36.1% and 59%, respectively. Gait speed (GS) was lower in the SO group as well, compared to the other groups. An average increase in GS of 0.1 m/sec reduced the likelihood of SO by 85.1%, in average. Sarcopenic obese older adults were 14.2 times more likely to be pre-fragile and 112.9 times more likely to be fragile than the other groups. Conclusion: The prevalence of obesity found in this study was higher than that in the general population, but similar to national statistics for the sample's mean age and gender. SO was directly associated with frailty in advanced and instrumental activities of daily living as well as gait speed and significantly increased the likelihood of being pre-frail and frail. GS may be an extremely useful tool for monitoring the progress of SO in older adults.
Resumo Introdução: A obesidade sarcopênica é uma condição de saúde que em idosos, pode resultar na incapacidade de utilizar os músculos de forma eficiente e tem sido associada a déficits funcionais e incapacidades. Objetivo: Identificar a prevalência da obesidade e obesidade sarcopênica (OS) e os fatores sociodemográficos, condições de saúde e medidas de desempenho funcional, associadas à OS em idosos comunitários. Métodos: Recorte do banco de dados do polo UFMG da Rede FIBRA. Participaram do estudo 1373 idosos divididos em três grupos 1) Não obesos; 2) Obesos não sarcopênicos; 3) Obesos sarcopênicos. OS foi definida por IMC ≥30 kg/m2 e baixa força de preensão palmar (FPP). Resultados: A prevalência de obesidade foi 25,85% e de OS foi 4,44%. Entre os obesos sarcopênicos a prevalência de fragilidade foi 36,1% e 59% de pré-frágilidade. A velocidade de marcha (VM) no grupo obeso sarcopênico, foi menor quando comparada aos outros grupos. Um aumento médio de 0,1m/seg na VM reduziu em média 85,1% a chance de se ter OS na amostra. Ser obeso sarcopênico aumentou em 14,2 vezes a chance de ser pré-frágil e 112,9 vezes a chance de ser frágil. Conclusão: A prevalência de obesidade foi maior que as taxas gerais, porém semelhante aos dados nacionais para a média de idade e sexo da amostra. OS se associou ao perfil de fragilidade, às atividades instrumentais e avançadas de vida diária e à velocidade de marcha. OS aumentou expressivamente a chance de o idoso ser pré-frágil e frágil e a VM pode ser uma ferramenta útil de acompanhamento da progressão da OS.
