          Abstract

          Resumo Objetivo Estimar a prevalência de sinais sugestivos de sarcopenia, bem como seus fatores associados, em pessoas idosas residentes em comunidades rurais ribeirinhas de Manaus. Método Estudo transversal de base domiciliar conduzido de abril a junho de 2021 com o universo de pessoas idosas (≥60 anos) que residiam em nove comunidades rurais ribeirinhas do rio Negro, Manaus, Amazonas, Brasil. Os sinais sugestivos de sarcopenia foram identificados por meio do Sarcopenia Formulary combinado à circunferência da panturrilha. Os aspectos sociodemográficos, o desempenho físico (equilíbrio estático em pé, velocidade de marcha em passo habitual e força muscular dos membros inferiores), a força de preensão palmar e as condições de saúde autorreferidas (hipertensão, diabetes, acidente vascular encefálico, dor lombar crônica e multimorbidade) representaram as variáveis explicativas. Utilizou-se regressão de Poisson com variância robusta para avaliação dos fatores associados aos sinais sugestivos de sarcopenia. Resultados Foram analisados os dados de 98 pessoas idosas (55,1% do sexo masculino), com idade média de 69,6±7,4 anos. Identificou-se que 50,5% apresentavam diminuição de força de preensão palmar, 52,6% incapacidade/baixo desempenho físico e 43,0% apresentaram multimorbidade. A ocorrência de sinais sugestivos de sarcopenia foi observada em 28,9% das pessoas idosas e associou-se à idade mais elevada (RP=1,1; IC95%=1,1-1,1) e ao maior número de moradores no domicílio (RP=1,2; IC95%=1,0-1,3). Conclusão Os achados do estudo evidenciaram elevada prevalência de sinais sugestivos de sarcopenia (28,9%) na população de pessoas idosas de localidades rurais ribeirinhas da Amazônia, sendo que maiores médias de idade e maior número de moradores no domicílio aumentaram a probabilidade de ocorrência dessa condição clínica.

          Abstract Objective To estimate the prevalence of signs suggestive of sarcopenia and its associated factors in an older rural riverside population of the Amazon. Method A cross-sectional household-based study was carried out from April to June 2021 involving the universe of older people (age ≥60 years) living in nine rural communities on the banks of the Rio Negro, Manaus city, Amazonas state, Brazil. Signs suggestive of sarcopenia were identified using the Sarcopenia Formulary combined with calf circumference. Sociodemographic aspects, physical performance (static standing balance, gait speed at usual pace, and chair sit and stand), handgrip strength and self-reported health conditions (hypertension, diabetes, stroke, chronic low-back pain and multimorbidity) represented the explanatory variables. Poisson regression with robust variance was used to assess factors associated with signs suggestive of sarcopenia. Results Data from 98 older individuals (55.1% male) with a mean age of 69.6±7.4 years were analyzed. Results revealed that 50.5% had low handgrip strength, 52.6% disability/low physical performance and 43.0% multimorbidity. Sarcopenia was identified in 28.9% of participants and associated with higher age (PR=1.1; 95%CI=1.1-1.1) and greater number of residents in the household (PR=1.2; 95%CI=1.0-1.3). Conclusion The findings of the study showed a high prevalence of signs suggestive of sarcopenia (28.9%) among the population of older people in rural riverside areas of the Amazon, where higher mean age and greater number of residents in the household increased the probability of occurrence of this clinical condition.

          Sarcopenia

          Sarcopenia is a progressive and generalised skeletal muscle disorder involving the accelerated loss of muscle mass and function that is associated with increased adverse outcomes including falls, functional decline, frailty, and mortality. It occurs commonly as an age-related process in older people, influenced not only by contemporaneous risk factors, but also by genetic and lifestyle factors operating across the life course. It can also occur in mid-life in association with a range of conditions. Sarcopenia has become the focus of intense research aiming to translate current knowledge about its pathophysiology into improved diagnosis and treatment, with particular interest in the development of biomarkers, nutritional interventions, and drugs to augment the beneficial effects of resistance exercise. Designing effective preventive strategies that people can apply during their lifetime is of primary concern. Diagnosis, treatment, and prevention of sarcopenia is likely to become part of routine clinical practice.

            Sarcopenia: revised European consensus on definition and diagnosis

            doi: 10.1093/ageing/afy169 In the original version of the above paper there was an error in Table 3, which shows the recommended cut-off points for ASM/height2 in women. The cut-off point was given as <6.0 kg/m2, but the correct value is <5.5 kg/m2. This has now been corrected online. The authors wish to apologise for this error.
