ABSTRACT BACKGROUND: Social distancing has led to lifestyle changes among older adults during the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVES: This study aimed to estimate the prevalence risk of sarcopenia (RS) and investigate its associated factors during the COVID-19 pandemic in older Brazilian adults. DESIGN AND SETTING: Cross-sectional observational analysis of baseline data as part of the Remobilize Study. METHODS: Participants in the study were older adults (≥ 60 years), excluding those who were bedridden or institutionalized. The data collected consisted of answers about the RS (SARC-F), functional status, walking, sedentary behavior (SB), pain, comorbidity, and life space mobility. RESULTS: A total of 1,482 older adults (70 ± 8.14 years, 74% women) participated in the study, and an RS prevalence of 17.1% was found. (95% confidence interval [CI] 15.25–19.15%). The adjusted multivariate model showed a significant association between RS and functional limitation (odds ratio [OR]: 19.05; CI 13.00–28.32), comorbidity (OR: 5.11; CI 3.44–7.81), pain (OR: 4.56; CI 3.33–6.28), total walking (OR: 0.99; CI 0.99–1.00), SB of 8–10 hours (OR: 1.85; CI 1.15–2.93), and SB of > 10 hours (OR: 3.93; CI 2.48–6.22). RS was associated with mobility during the pandemic (OR: 0.97; CI 0.96–0.98). P < 0.05. CONCLUSIONS: During the pandemic, the prevalence of RS in older Brazilians was estimated at 17.1%. Moderate to severe functional limitation, comorbidities, presence of pain, walking, longer SB period, and reduced life space mobility significantly contributed to RS in older adults during the pandemic.

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.

Objetivo: O presente trabalho tem como objetivo sistematizar evidências científicas sobre a utilização dos exercícios de alongamento muscular no tratamento da fibromialgia (FM). Metodologia: Foi realizado a partir de consulta retrospectiva, sem limite cronológico e linguístico, às bases de dados MedLine, LILACS, SciELO e PEDro, além da ferramenta de busca PubMed. A coleta foi realizada por dois revisores independentes, em outubro de 2012, sendo a estratégia de busca formulada por meio do cruzamento de descritores e termos relevantes para o tema nos idiomas inglês, português e espanhol. Foram incluídos ensaios clínicos randomizados (ECRs) compostos apenas por pacientes com diagnóstico clínico de FM e com exercícios de alongamento muscular como medida terapêutica em pelo menos um dos grupos de intervenção. Os estudos incluídos foram avaliados quanto à qualidade metodológica por meio da escala PEDro, e suas referências bibliográficas, analisadas, para se destacar fontes adicionais. A busca totalizou 6.794 artigos. Cinco artigos foram selecionados, sendo um deles excluído por apresentar baixa qualidade metodológica. A dor foi avaliada por unanimidade. O método e o tempo das intervenções variaram amplamente, houve falta de menção de parâmetros na utilização dos alongamentos e ausência de exames físicos específicos. Resultados: Houve melhora significativa em todos os estudos quanto à dor, além de aspectos relacionados a qualidade de vida e condição física. Conclusão: É evidente a importância do alongamento muscular no tratamento da FM, porém observa-se a necessidade de novos estudos para se estabelecer os reais benefícios da técnica, visto que a maioria dos trabalhos publicados apresenta baixa qualidade metodológica e ausência de padronização quanto ao uso desse recurso.

Objective: this study has the objective to systematize scientific evidences about the use of muscle stretching exercises in the treatment of FM. Methodology: it was performed from retrospective research without chronological and linguistic limits, at databases of MEDLINE, LILACS, SciELO and PEDro, as well as at PubMed search tool. Data collection was performed by two independent reviewers in October 2012, with the search strategy formulated by crossing descriptors and relevant terms to the topic in English, Portuguese and Spanish languages. Randomized clinical trials, only with patients with a clinical diagnosis of fibromyalgia and muscle stretching exercises as a therapeutic measure at least in one of the intervention groups were included. Included studies were assessed for methodological quality using PEDro scale and their references analyzed to highlight additional sources. The search amounted to an average of 6,794 items. Only five articles were selected, one being excluded because of its low methodological quality. Pain was assessed unanimously. The method and timing of interventions varied widely, there was poor mention of the parameters used in the stretches and absence of specific physical examinations. Results: there was significant improvement in all studies regarding pain, besides as related to quality of life and physical condition. Conclusion: it is clear the importance of muscle stretching in the treatment of FM, however, there is a need for further studies to establish the real benefits of the technique, because the majority of published studies shows low methodological quality and there is a lack of standardization regarding the use of this resource.
