Objetivo: relacionar el Síndrome de la Fragilidad y la sarcopenia en ancianos con y sin diabetes mellitus tipo 2; e identificar los potenciales factores de riesgo para la fragilidad y sarcopenia. Método: estudio epidemiológico descriptivo realizado en 140 ancianos del municipio de Sinop, Mato Grosso, Brasil. Para evaluar el Síndrome de la Fragilidad se utilizó el fenotipo de fragilidad y para la evaluación de la sarcopenia el cuestionario de evaluación física con medida de la circunferencia de la pantorrilla. Resultados: en lo que se refiere al Síndrome de la Fragilidad se obtuvo un mayor porcentaje para ancianos con diabetes mellitus tipo 2, cuando comparados con aquellos sin la enfermedad (p = 0,00). En relación a la presencia de sarcopenia, los ancianos con y sin diabetes mellitus tipo 2 presentaron valores semejantes, sin significación estadística (p = 0,74). El Síndrome de la Fragilidad presentó asociación con: inactividad física (IC95%: 3,29-56,55); intervalo etario superior a 75 años (IC95%: 3,30-27,82); baja renta familiar (IC95%: 1,80-50,98); y, comorbilidades (IC95%: 4,9-5,4). Entre tanto, la sarcopenia fue asociada a la presencia de la inactividad física (IC95%: 1,26-10,44), al bajo peso/eutrófico (IC95%: 3,32- 26,76) y a la desnutrición/riesgo nutricional (IC95%: 1,30-7,70), en los ancianos con y sin diabetes mellitus tipo 2. Conclusión: los ancianos diabéticos tienen mayor vulnerabilidad para desarrollar el Síndrome de Fragilidad, lo que requiere la adopción de medidas preventivas en la atención primaria a la salud.

Objective: to relate Frailty Syndrome and sarcopenia in older adults with and without type 2 diabetes mellitus and identify potential risk factors for frailty and sarcopenia. Method: this descriptive epidemiological study was conducted with 140 older adults in the municipality of Sinop, Mato Grosso, Brazil. The frailty phenotype was used for the assessment of Frailty Syndrome, and a physical assessment questionnaire with calf circumference measurement was used for the assessment of sarcopenia. Results: regarding Frailty Syndrome, a higher percentage was observed in older adults with type 2 diabetes mellitus compared to those without the disease (p = 0.00). Concerning the presence of sarcopenia, older adults with and without type 2 diabetes mellitus showed similar values, with no statistical significance (p = .74). Frailty Syndrome was associated with physical inactivity (95%CI: 3.29-56.55), age over 75 years (95%CI: 3.30- 27.82), low family income (95%CI: 1.80-50.98), and comorbidities (95%CI: 4.90-5.40). However, sarcopenia was associated with the presence of physical inactivity (95%CI: 1.26-10.44), low weight/ eutrophic (95%CI: 3.32-26.76), and malnutrition/nutritional risk (95%CI: 1.30-7.70) for older adults with and without type 2 diabetes mellitus. Conclusion: older adults with diabetes have a higher vulnerability to develop Frailty Syndrome, necessitating the adoption of preventive measures in primary healthcare.

Sarcopenia, obesity and sarcopenic obesity among community-dwelling and institutionalized older women in Caxias do Sul, Brazil / Sarcopenia, obesidade e obesidade sarcopênica em idosas da comunidade e institucionalizadas de Caxias do Sul, Brasil

INTRODUCTION: Sarcopenia, obesity, and sarcopenic obesity are considered risk factors for the health of the elderly, which may cause or worsen the reduction in functional capacity. OBJECTIVE: To determine the prevalence of sarcopenia, obesity, and sarcopenic obesity among community-dwelling and institutionalized female elderly in Caxias do Sul, Brazil. METHODS: Observational epidemiological study, with cross-sectional design. 423 elderly women (≥60 years old) institutionalized and community-dwellers, participated in the study. Sarcopenia was identified according to the criteria established by the European Working Group on Sarcopenia in Older People (EWGSOP). The gait speed test estimated low skeletal muscle mass (SMM) by bioimpedance, low handgrip strength using a hand dynamometer, and low physical performance. Obesity was defined as Body Mass Index ≥27.0kg/m² and sarcopenic obesity by the simultaneous occurrence of obesity and sarcopenia. The Chi-Square test was performed, with a 5% significance level. RESULTS: The overall prevalence of obesity was 53.9%. Sarcopenia was observed in 16.3% of the total sample, affecting 7.5% of the elderly in the community and 25.1% in institutions (p≤0.0001). Regarding sarcopenic obesity, 0.9% of the community and 3.8% of institutionalized elderly presented the dysfunction. Non-sarcopenic elderly women had a high prevalence of obesity. In the elderly of both groups, sarcopenia was more frequent in those with advanced age. CONCLUSION: Institutionalized elderly women had a higher prevalence of sarcopenia, emphasizing the importance of paying attention to the health of this population and highlighting the need for preventive measures.

Realizou-se o teste Qui-Quadrado e regressão de Poisson, com nível de significância de 5%. RESULTADOS: A prevalência geral de obesidade foi de 53,9%. 16,3% da amostra total apresentava sarcopenia, presente em 7,5% das idosas da comunidade e 25,1% das institucionalizadas (p≤0.0001). Referente a obesidade sarcopênica 0,9% da comunidade e 3,8% das institucionalizadas apresentaram a disfunção. Idosas não sarcopênicas apresentaram elevada prevalência de obesidade. Nas idosas de ambos os grupos, a sarcopenia foi mais frequente naquelas com idade avançada. CONCLUSÃO: Idosas institucionalizadas apresentaram maior prevalência de sarcopenia, acentuando a importância em atentar à saúde desta população e evidenciando a necessidade de medidas preventivas.

Osteosarcopenia and trabecular bone score in patients with type 2 diabetes mellitus

ABSTRACT Objective: To evaluate the prevalence of osteosarcopenia and the association of osteosarcopenia with trabecular bone score (TBS) in a group of patients with type 2 diabetes mellitus(T2DMG) compared with a paired control group (CG). Materials and methods: Cross-sectional study with men and women ≥ 50 years recruited by convenience. Patients in both groups answered questionnaires and underwent evaluation of bone mineral density (BMD), handgrip strength (HGS), and TBS. The T2DMG also underwent a gait speed (GS) test. Sarcopenia was defined as low lean mass plus low HGS or GS according to the Foundation for the National Institute of Health Sarcopenia Project, and osteosarcopenia was deemed present when sarcopenia was associated with osteopenia, osteoporosis, or low-energy trauma fractures. Results: The T2DMG (n = 177) and CG (n = 146) had, respectively, mean ages of 65.1 ± 8.2 years and 68.8 ± 11.0 years and 114 (64.4%) and 80 (54.7%) women. T2DMG versus the CG had higher rates of osteosarcopenia (11.9% versus 2.14%, respectively, p = 0.010), sarcopenia (12.9% versus 5.4%, respectively, p < 0.030), and fractures (29.9% versus 18.5%, respectively, p = 0.019), and lower HGS values (24.4 ± 10.3 kg versus 30.9 ± 9.15 kg, respectively, p < 0.001), but comparable BMD values. Mean TBS values were 1.272 ± 0.11 and 1.320 ± 0.12, respectively (p = 0.001). On multivariate analysis, age, greater waist circumference, fractures, and osteoporosis increased the risk of degraded TBS. Osteosarcopenia was associated with diabetes complications (p = 0.03), calcium and vitamin D supplementation (p = 0.01), and all components of osteosarcopenia diagnosis (p < 0.05). Conclusion: Compared with the CG, the T2DMG had a higher prevalence of osteosarcopenia, sarcopenia, and fractures and lower bone quality assessed by TBS.

A low phase angle determined by bioelectrical impedance analysis is associated with oropharyngeal dysphagia among institutionalized older adults

SUMMARY OBJECTIVE The aim was to evaluate the prevalence of oropharyngeal dysphagia (OD) and its association with body composition by bioelectrical impedance analysis (BIA) and functionality among institutionalized older adults. METHODS A cross-sectional study was conducted. The swallowing function and diagnosis of OD were evaluated with a volume-viscosity swallow test. Activities of daily living were evaluated by the Barthel Index. Body composition was evaluated by BIA, and phase angle (PhA) was determined. RESULTS Eighty institutionalized older adults were evaluated. The mean age of the study population was 82±9.5 years, and 65% were females. The OD prevalence was 30%, dependence was 30%, and sarcopenia was 16%. In the multivariate analysis, a low PhA (<3.5°) was independently associated with the presence of OD adjusted by sex and age (OR: 2.60, 95%CI 2.41-2.90, p=0.01). CONCLUSIONS A higher prevalence of OD was found. Significant and independent associations were found between low PhA, dependence, and sarcopenia with the presence of OD among institutionalized older persons.

Prevalencia de sarcopenia en población adulta mayor en Costa Rica / Prevalence of sarcopenia in the elderly population in Costa Rica

Resumen Sarcopenia es la progresiva disminución de la masa y la fuerza muscular. Su prevalencia varía en la literatura por los distintos métodos de medición. Costa Rica no cuenta con datos de su prevalencia. Objetivo: Determinar la prevalencia de sarcopenia y los factores asociados en adultos mayores de Costa Rica: Estudio de Longevidad y Envejecimiento Saludable. Métodos: Un subgrupo de 2516 personas adultas mayores. Se utilizaron los criterios diagnósticos del Grupo Europeo de Trabajo sobre la Sarcopenia en Personas Mayores, que incluye baja masa muscular y baja fuerza muscular. Para la masa muscular se utilizó la circunferencia de pantorrilla menor a 31 cm, y para la fuerza muscular una medición por dinamometría, siendo baja fuerza si los hombres tenían <27 kg en la prensión y las mujeres <16 kg. Resultados: La prevalencia de sarcopenia fue de 10.26%. La tendencia aumentó conforme aumentaba la edad y fue más prevalente en mujeres. La mayoría de los sarcopénicos tuvieron menos ingresos económicos, viven acompañados, se perciben como no saludables, y tienen primaria incompleta. El peso, la circunferencia braquial, abdominal y la circunferencia de pantorrilla fueron menores en las personas con sarcopenia. Asociaciones positivas se encontraron con sarcopenia la edad mayor de 70 años (OR=3,164; IC 1,962-5,101), el nivel educativo (OR 4,264; IC 1,547-11,753), percibirse poco saludable (OR 1,691; IC 1,133-2,525), tener antecedente de enfermedad vascular cerebral (OR 3,221; IC 1,566-6,628), artritis (OR 1,648; IC 1,044-2,601) y caídas (0R 1,676; IC 1,143-2,458). Conclusiones: La prevalencia de sarcopenia fue 10.26%, similar a otros países de Latinoamerica. Su presencia incrementa con la edad.

Abstract Background: Sarcopenia is the progressive loss of mass and skeletal muscle strength. Its prevalence varies in the different reviews carried out, this by the different measurement methods. Costa Rica does not have data on its prevalence. Objective: The aim of this study is to know the prevalence of sarcopenia and associated factors with it in older people from Costa Rican Study of Longevity and Healthy Ageing. Methods: A subgroup of 2516 people was analyze, using the European Working Group on Sarcopenia in Older People diagnostic criteria that include low muscle mass and low muscle strength. Muscle mass was assessed using calf circumference < 31 cm and grip strength using dynamometer, was low strength if <27 kg in men or <16 kg in women. Results: The prevalence of sarcopenia was 10.26%. There was an increasing trend of sarcopenia by age group, it was more prevalent in women. Some characteristics of Costa Ricans with sarcopenia was that most of them had less income, lived accompanied, perceived as unhealthy, had incomplete primary education. The weight, brachial, abdominal and calf circumference was lower in people with sarcopenia. Sarcopenia was positively associated with age (OR 3,164; IC 1,962-5,101), education (OR 4,264; IC 1,547- 11,753), perceived as unhealthy (OR 1,691; IC 1,133-2,525), antecedent of ischemic vascular event (OR 3,221; IC 1,566-6,628), arthritis (OR 1,648; IC 1,044-2,601), and falls (0R 1,676; IC 1,143-2,458). Conclusions: The prevalence of sarcopenia was 10.26%, similar to other countries of Latin America. It increase with age.

Postmenopausal women with sarcopenia have higher prevalence of falls and vertebral fractures / Las mujeres postmenopáusicas con sarcopenia tienen mayor prevalencia de caídas y fracturas vertebrales

Abstract Recently, a new consensus of the European Working Group on Sarcopenia in Older People (EWSOP2) recommended new cut-off points for the diagnosis of sarcopenia. The aim of the present manuscript was to assess the prevalence of sarcopenia in postmenopausal women and its relationship with bone mineral density, falls and fragility fractures according to EWGSOP2. In this cross-sectional study, 250 ambulatory postmenopausal women over 60 years of age were included. Lumbar spine and hip bone mineral density (BMD) and whole-body composition were assessed by dual-energy X-ray absorptiometry (DXA). Muscle strength was evaluated by handgrip dynamometry and physical performance by a 4-m walk gait speed and five-repetition sit-to-stand test. Sarcopenia was defined according to EWGSOP2 as low muscle strength (handgrip) and low muscle mass (appendicular skeletal muscle mass index by DXA). A sarcopenia prevalence of 4% was found in the whole group increasing with age being 12.5% in ≥ 80year-old. A higher percentage of falls, prevalence of osteoporosis and vertebral fractures were found in the sarcopenic group. Sarcopenia increased 6.0-fold the likelihood of having a fragility fracture. Women with sarcopenia had significantly lower femoral neck BMD and higher frequency of falls and vertebral fractures. According to our results, identifying patients with sarcopenia might be a useful tool to detect adults at higher risk of falls and fractures.

Resumen Recientemente el grupo de trabajo europeo sobre sarcopenia en adultos mayores (EWGSOP2) recomendó nuevos criterios y valores de referencia para el diagnóstico de sarcopenia. El objetivo del presente trabajo fue evaluar la prevalencia de sarcopenia en mujeres postmenopáusicas en nuestro medio y su relación con densidad mineral ósea, caídas y fracturas por fragilidad. Este es un estudio de diseño transversal en el cual se incluyeron un total de 250 mujeres ambulatorias mayores de 60 años. La densidad mineral ósea (DMO) de columna lumbar y cadera y la composición corporal fueron evaluados por absorciometría dual de rayos X (DXA). La fuerza fue evaluada por dinamometría de puño; para el rendimiento físico se utilizó caminata de 4 m y la prueba de levantarse y sentarse de una silla (5 repeticiones). La sarcopenia se definió de acuerdo a EWGSOP2 como baja fuerza muscular (dinamometría) y baja masa muscular (índice de masa muscular esquelética por DXA). El 4% de las mujeres cumplía con los criterios de sarcopenia siendo aún mayor en aquellas ≥ 80 años. Las mujeres con sarcopenia presentaron significativamente mayor frecuencia de caídas, osteoporosis y fracturas vertebrales. El riesgo de fracturas por fragilidad se vio incrementado 6 veces en las mujeres con sarcopenia. El diagnóstico de sarcopenia podría considerarse una herramienta útil para identificar a aquellos adultos con riesgo incrementado de caídas y fracturas.

Predictors of sarcopenia in young hospitalized patients living with HIV

ABSTRACT The prevalence of sarcopenia in hospitalized people living with HIV is underdiagnosed, as assessment instruments are not always available. This study aimed to identify factors related to sarcopenia, correlating their anthropometric and clinical markers in hospitalized people living with HIV. This was an observational cross-sectional clinical study, carried out from September 2018 through October 2019. Handgrip strength, muscle mass index, calf circumference and gait speed test were evaluated in recruited patients within three days of hospital admission. The sample consisted in 44 patients, mostly men (66%), black (68%), young adults (41.65 ± 12.18 years) and immunodeficient (CD4 cell count 165 cells/mm3 [34.25-295.5]). Sarcopenia was present in 25% of the sample. Calf circumference showed a significant correlation with CD4 cell count and viral load (p < 0.05) while handgrip strength and gait speed test did not. Calf circumference > 31 cm and gait speed test > 0.8 m/s reduced the chance of sarcopenia by 60% (OR = 0.396 [−1.67 to −0.18]; p < 0.05) and 98% (OR = 0.02 [−8.16 to 0.13]; p < 0.05) respectively. Calf circumference > 31 cm and gait speed test > 0.8 m/s are associated with a reduced chance of sarcopenia in hospitalized HIV patients.

Resumo Objetivo O objetivo deste estudo foi comparar a qualidade de vida entre idosos sarcopênicos e não sarcopênicos e verificar a associação entre sarcopenia e qualidade de vida em idosos residentes na comunidade. Métodos Estudo transversal conduzido com idosos residentes na comunidade (n = 378) de Macapá, Amapá, Brasil. A qualidade de vida foi avaliada por meio do Short Form (36) Health Survey. O algoritmo proposto pelo Grupo de Trabalho Europeu sobre Sarcopenia em Pessoas Idosas (EWGSOP) foi usado para avaliar a sarcopenia. Foram realizadas análises descritivas, inferenciais e modelo de regressão linear. Resultados Os idosos sarcopênicos apresentaram escores de qualidade de vida significativamente mais baixos nos domínios função física, dor corporal, estado geral de saúde e função social. Após o ajuste, a sarcopenia associou-se inversamente ao funcionamento físico (β = -0,125; p = 0,010) e ao estado geral de saúde (β = -0,112; p = 0,028). Conclusão Os resultados deste estudo sugerem um provável declínio na qualidade de vida em idosos sarcopênicos, principalmente nos domínios funcionamento físico e estado geral de saúde.

Abstract Objective This study aimed to compare quality of life between sarcopenic and non-sarcopenic older adults and to verify the association of sarcopenia and quality of life in community-dwelling older adults. Methods This was a cross-sectional study conducted in community-dwelling older adults (n = 378) from Macapá, Amapá, Brazil. Quality of life was assessed using the Short Form (36) Health Survey. The algorithm proposed by the European Working Group on Sarcopenia in Older People (EWGSOP) was used to assess sarcopenia. Descriptive, inferential analyses and linear regression model were performed. Results Sarcopenic older adults presented significantly lower quality of life scores in the domains of physical functioning, bodily pain, general health status, and social functioning. After adjustment, sarcopenia was inversely associated with physical functioning (β = -0.125; p = 0.010) and general health status (β = -0.112; p = 0.028). Conclusion The results of this study suggest a probable decline in the quality of life in sarcopenic older adults, especially in the physical functioning and general health status domains.

Sarcopenia, definición y diagnóstico: ¿Necesitamos valores de referencia para adultos mayores de Latinoamérica? / Sarcopenia, definition and diagnosis: do we need reference values in older adults from latin america?

La sarcopenia es uno de los principales síndromes geriátricos que está asociada con limitación en las actividades de la vida diaria, discapacidad y mortalidad en la población adulta mayor. Sin embargo, su definición, criterios diagnósticos y puntos de corte son diversos en la literatura, lo que dificulta el diagnóstico de la sarcopenia. El objetivo de esta revisión narrativa fue detectar en la literatura todos los consensos internacionales relacionados con sarcopenia, comparar su definición, criterios diagnósticos y puntos de corte, con el propósito de identificar una definición y criterios que puedan ser utilizados en Latinoamérica. Fueron identificados 7 consensos internacionales que han definido la sarcopenia como un síndrome/enfermedad caracterizado por la pérdida de la masa y función muscular asociada al proceso de envejecimiento. A pesar de tener una definición similar, no hay una total concordancia entre los criterios y evaluaciones. La sarcopenia puede ser detectada utilizando evaluaciones funcionales de fuerza muscular, velocidad de la marcha y equilibrio, que son frecuentemente utilizados por profesionales del área de la rehabilitación. Adicionalmente, el riesgo de sarcopenia puede ser identificado utilizando los cuestionarios SARC-F y SARC-CalF. Debido a su impacto funcional, la sarcopenia debería ser diagnosticada precozmente en adultos mayores por terapeutas ocupacionales, kinesiólogos y fisioterapeutas, para prevenir y tratar futuras complicaciones clínicas y funcionales en esta población. Es necesario la creación de valores de referencia para favorecer el diagnóstico de la sarcopenia en población latinoamericana.

Sarcopenia is one of the main geriatric syndromes that has been associated with limitation in activities of daily living, disability, and mortality in the elderly population. However, the definition, diagnostic criteria and cut-off points are diverse in the literature, which makes the diagnosis of sarcopenia difficult. The aim of this narrative review was to detect in the literature all the international consensus related to sarcopenia, to compare their definition, diagnostic criteria and cut-off points, in order to identify a definition and criteria that can be used in Latin America. Seven international consensuses were identified that have defined sarcopenia as a syndrome / disease characterized by loss of muscle mass and function associated with the aging process. Despite having a similar definition, there is not a total concordance between the criteria and evaluations. Sarcopenia can be detected using functional assessments of muscle strength, gait speed, and balance, which are frequently used by professionals in the area of rehabilitation. Additionally, the risk of sarcopenia can be assessed using SARC-F and SARC-CaF. Due to its functional impact, sarcopenia should be diagnosed early in older adults by occupational therapists, physical therapists and physiotherapists, to prevent and treat future clinical and functional complications in this population. The creation of reference values is necessary to favor the diagnosis of sarcopenia in the Latin American population.

Sarcopenia, bone mineral density, and vitamin D: EpiFloripa aging study 2013/2014 / Sarcopenia, densidade mineral óssea e vitamina D: Estudo EpiFloripa Idoso 2013/2014

OBJECTIVE: To verify associations between osteopenia/osteoporosis and vitamin D and sarcopenia in the older adult population of Florianópolis, Brazil. METHODS: A cross-sectional population-based study, with 604 older adults (60 years and over). The appendicular muscle mass index (AMMI) was used to identify sarcopenia, with cutoffs of AMMI (Kg/m2) < 7.26 kg/m2 for men and < 5.50 kg/m2 for women indicating inadequate values (sarcopenia). The independent variable osteopenia/osteoporosis was measured using bone mineral density (BMD, g/cm2): T-Scores for whole body BMD, lumbar spine BMD, and femoral neck BMD, categorized as normal (BMD > -1 SD) or osteopenia/osteoporosis (BMD < -1 SD from the mean of the young adult reference population). Fasting serum samples were collected and assayed using the microparticle chemiluminescence (CMIA)/Liaison method. Vitamin D concentrations of < 30 ng/mL were defined as hypovitaminosis. Crude and adjusted logistic regression analyses were performed. RESULTS: Osteopenia/osteoporosis in the lumbar spine and femoral neck were associated with higher odds of sarcopenia in women and men. Osteopenia/osteoporosis in the whole body was associated with sarcopenia in women only. Vitamin D was not associated with sarcopenia in either sex. CONCLUSIONS: Having osteopenia/osteoporosis was associated with sarcopenia in this older adult population.

OBJETIVO: Verificar a associação entre osteopenia/osteoporose e vitamina D com a sarcopenia na população idosa de Florianópolis. METODOLOGIA: Estudo transversal de base populacional, com 604 idosos (60 anos ou mais). O índice de massa muscular apendicular (IMMA) foi utilizado para identificar a sarcopenia, onde o IMMA (Kg/m2) ­ < 7,26 kg/m2 para homens e < 5,50 kg/m2 para mulheres ­ indicava valores inadequados (sarcopenia). A variável independente osteopenia/ osteoporose foi medida pela densidade mineral óssea (DMO, g/cm2), foram calculados os T-escores para DMO corporal total, DMO da coluna lombar e DMO do colo femoral, categorizados como normais (DMO até -1 DP) ou osteopenia/osteoporose (DMO < -1 DP da média da população adulta jovem de referência). Amostras de soro em jejum foram coletadas pelo método de quimioluminescência de micropartículas (CMIA)/Liaison. Concentrações de vitamina D < 30 ng/mL foram definidas como hipovitaminose. Foi realizada análise de regressão logística bruta e ajustada. RESULTADOS: Osteopenia/osteoporose na coluna lombar e colo do fêmur foram associadas a maiores chances de sarcopenia em mulheres e homens. Osteopenia/ osteoporose no corpo total foi associada à sarcopenia apenas em mulheres. A vitamina D não foi associada à sarcopenia em ambos os sexos. CONCLUSÕES: A presença de osteopenia/osteoporose associou-se à sarcopenia nesta população de idosos.

Sarcopenia in children and adolescents with chronic liver disease / Sarcopenia em crianças e adolescentes com doença hepática crônica

Abstract Objective: To investigate the occurrence of sarcopenia in children and adolescents with chronic liver disease. Methods: A series of cases, with patients aged 6-19 years of both genders, who were treated in Liver Outpatient Clinics. Weight, height, muscle strength (assessed by manual grip strength), and muscle mass (estimated through dual-energy X-ray absorptiometry) were measured. Sarcopenia was diagnosed based on the simultaneous presence of muscle mass and muscle strength déficits, defined as the values below the mean for muscle mass and strength of the studied population, according to gender. A descriptive analysis (mean and standard deviation) was performed, and the difference of means was calculated by Student's t-test. Results: A total of 85 patients were studied, mostly females (64.7%), with a mean age of 11.7 (SD = 3.4) years. Sarcopenia was identified in 40% of the patients. Muscle strength déficit was found in 54.1% of the subjects, and 50.6% showed muscle mass déficit. The mean muscle mass for males was higher than that for females (6.07; SD = 1.22 kg/m2 vs. 5.42; SD = 1.10 kg/m2; p = 0.016). However, there was no significant difference in sex-related muscle strength (male = 0.85; SD = 0.52 kgf/kgm2 and female = 0.68; SD = 0.30 kgf/kgm2; p = 0.113). Conclusion: The research findings identified that sarcopenia is a condition found in pediatric patients treated at a public referral institution for chronic liver disease.

Resumo Objetivo: Investigar a ocorrência de sarcopenia em crianças e adolescentes com hepatopatias crônicas. Métodos: Série de casos, constituído por pacientes entre 6 e 19 anos, de ambos os sexos, acompanhados em ambulatórios de especialidade em hepatopatias. Foram feitas medidas de peso, altura, força muscular (avaliada pela força de preensão manual) e a massa muscular estimada a partir da absorciometria por dupla emissão de raios X. O diagnóstico de sarcopenia baseou-se na presença simultânea de déficit de massa muscular e de força muscular. Adotaram-se como déficit os valores abaixo da média para massa e força muscular da população estudada, segundo sexo. Realizou-se análise descritiva (média e desvio-padrão), bem como a diferença de médias com o teste do t de Student. Resultados: Foram estudados 85 pacientes, a maioria do sexo feminino (64,7%), com média de 11,7 (DP = 3,4) anos. A sarcopenia foi identificada em 40% dos pacientes, 54,1% apresentaram déficit de força muscular e 50,6% déficit de massa muscular. A média da massa muscular para o sexo masculino foi maior do que no feminino (6,07; DP = 1,22 kg/m2 vs 5,42; DP = 1,10 kg/m2; p = 0,016). No entanto, não houve diferença significante para força muscular com relação aos sexos (masculino = 0,85; DP = 0,52 kgf/kgm2 e feminino = 0,68; DP = 0,30 kgf/kgm2; p = 0,113). Conclusão: Os achados da pesquisa identificaram que a sarcopenia é uma condição presente em pacientes pediátricos atendidos em uma instituição pública de referência para doença hepática crônica.

Sarcopenia and consumptive syndrome in HIV-infected patients receiving antiretroviral therapy in a public hospital in Northeast Brazil / Sarcopenia y síndrome de emaciación en pacientes infectados por el HIV que reciben terapia antiretroviral en un hospital público en el noreste Brasil

We evaluated the prevalence of sarcopenia and wasting syndrome, as well as the associated factors in HIV-infected patients receiving antiretroviral therapy. We utilized a cross-sectional study evaluating HIV-infected individuals at a university hospital in the Northeast area of Brazil. In 99 patients, sarcopenia was assessed by analysis of muscle mass, muscle strength and physical performance. Wasting syndrome was assessed by unintentional weight loss criteria. Demographic, socioeconomic, anthropometric, as well as clinical and lifestyle variables were also evaluated. The prevalence of sarcopenia in this sample was 18.2% and 33.3% presented severe sarcopenia. Wasting syndrome was identified in 13.1% and 4% presented both conditions. Sarcopenia had higher prevalence in older patients (80.0 vs 4.9%, p= 0.004), among those with diabetes mellitus (50.0 vs 16.1%, p= 0.037), as well as among malnourished individuals (p= 0.003). Wasting syndrome was more prevalent in individuals with a lower level of education (26.3%vs5.4%, p= 0.005), in the lower income tertile (p= 0.041), and a lower CD4+ T cell count (429±450 vs 654±321 cells/mm3, p= 0.045). Sarcopenia and wasting syndrome are still clinical problems present in those using antiretroviral therapy associated with specific conditions in HIV patients.

Se evaluó la prevalencia de la sarcopenia, síndrome de emanciación y factores asociados en pacientes infectados por HIV que recibieron terapia antirretroviral. En la evaluación de las personas infectadas por el HIV se aplicó un diseño de tipo transversal y fue realizado en un hospital universitario en la zona noreste del Brasil. La sarcopenia se evaluó mediante la medición de la masa muscular, la fuerza muscular y el rendimiento físico. El síndrome de emanciación se evaluó mediante criterios de pérdida de peso involuntarios. También se evaluaron las características demográficas, socioeconómicas, antropométricas, así como las variables clínicas y de estilo de vida. La prevalencia de sarcopenia en esta muestra de pacientes fue del 18,2%, y de esta población un tercio presentó sarcopenia grave. El síndrome de emanciación se identificó en el 13,1% de los pacientes y en el 4% de los sujetos que presentaron ambas condiciones. La sarcopenia tenía mayor prevalencia en pacientes de mayor edad (80,0 vs 4,9%, p= 0,004), en las personas con diabetes mellitus (50,0 vs 16,1%, p= 0,037), así como en sujetos desnutridos (p= 0,003). El síndrome de emanciación fue más prevalente en sujetos con un nivel más bajo de educación (26,3% vs 5,4%, p= 0,005), menor tercil de ingresos (p= 0,041), y menor recuento de células TCD4+ (429±450 vs 654±321 células/mm3, p= 0,045). Sarcopenia y síndrome de emanciación son todavía problemas clínicos presentes en aquellos que utilizan la terapia antirretroviral asociada con condiciones específicas en pacientes con HIV.

A duração e a frequência da prática de atividade física interferem no indicativo de sarcopenia em idosos? / ¿La duración y la frecuencia de la actividad física interfieren con la indicación de sarcopenia en los ancianos? / Do the duration and frequency of physical activity affect the indicator of sarcopenia in older adult?

RESUMO A sarcopenia é uma síndrome caracterizada pela perda progressiva de massa muscular e está associada a desfechos adversos na saúde de idosos. A atividade física tem sido apontada como uma importante ferramenta para a prevenção da sarcopenia. Diante disso, este estudo investigou a relação da duração e frequência da prática de atividade física com os indicativos de sarcopenia de idosos. Participaram deste estudo transversal 551 idosos praticantes de atividade física nas academias da terceira idade do município de Maringá (PR). Como instrumentos foram utilizados o international physical activity questionnaire (IPAQ) e o SARC-F. A análise dos dados foi conduzida por meio dos testes de Kolmogorov-Smirnov, correlação de Spearman e a análise de equações estruturais (p<0,05). Os resultados evidenciaram que os idosos deste estudo realizam atividades físicas leves (Md=3) e moderadas (Md=2) semanalmente, mas não praticam atividades vigorosas (Md=0), e apresentam baixo indicativo de sarcopenia (Md=1). A análise de equações estruturais revelou que as variáveis de atividades leves e moderadas apresentaram associação significativa (p<0,05), e negativa com o escore de indicativo de sarcopenia, entretanto fraca (β<0,20), explicando 7% da sua variabilidade. Concluiu-se que a prática de atividades física leves e moderadas parece ser fator interveniente no indicativo de sarcopenia em idosos.

Se concluyó que la práctica de actividades físicas leves y moderadas parece ser un factor interviniente en el indicativo de sarcopenia en ancianos.

ABSTRACT Sarcopenia is a syndrome characterized by progressive loss of muscle mass and associated with adverse health outcomes in older adults. Physical activity has been pointed out as an important tool for its prevention. Therefore, this study investigated the relationship of sedentary lifestyle, duration and frequency of physical activity with the indicator of sarcopenia in older adults. Five hundred and fifty-one physically active older adults enrolled in senior fitness centers of Maringá (PR) participated in this cross-sectional study. The International Physical Activity Questionnaire (IPAQ) and the SARC-F were the instruments used. Data analysis was conducted using the Kolmogorov-Smirnov tests, Spearman correlation coefficient and the Structural Equation Analysis (p<0.05). Results showed that older adults participated in mild to moderate physical activities weekly, but not vigorous ones, besides exhibiting low sarcopenia indicators. Structural Equations analysis revealed that the variables of mild and moderate activity presented a significant (p<0.05) and negative correlations with the sarcopenia indicators score, however weak (β<0.20), explaining its 7% variability. It was concluded that the practice of mild and moderate physical activity affect sarcopenia indicators in older people.

Prevalence of sarcopenic obesity and its association with functionality, lifestyle, biomarkers and morbidities in older adults: the Fibra-RJ study of frailty in older brazilian adults

OBJECTIVES: To assess the prevalence of sarcopenic obesity and its association with functionality, lifestyle, biomarkers, and morbidities in older adults. METHODS: The study analyzed cross-sectional data from 270 older adults who participated in phase III of the Frailty in Brazilian Older People Study (Fragilidade em Idosos Brasileiros—Rio de Janeiro, FIBRA-RJ study-2013). They took part in a home interview surveying socioeconomic, demographic, lifestyle, morbidities, and functional data. Blood was collected for biochemical marker analysis and participants' body composition was determined by dual-energy X-ray absorptiometry. For women, the diagnosis of sarcopenic obesity was defined at a body fat percentage ≥38% and appendicular skeletal muscle mass index (ASMMI) <5.45 kg/m2. For men, a fat percentage ≥27% and ASMMI <7.26 kg/m2 was defined as sarcopenic obesity. Multivariate analysis was performed using a multinomial regression model (95% confidence intervals), with sarcopenic obesity as the outcome. RESULTS: The prevalence of sarcopenic obesity was 29.3%. In the final fitted model, the variables that displayed statistically significant association with sarcopenic obesity were lower gait speed, self-reported medical diagnosis of arthrosis or arthritis, and high levels of glycemia. CONCLUSION: The study showed a high prevalence of sarcopenic obesity in non-institutionalized older adults in Brazil. The finding that this condition was associated with modifiable risk factors may provide insights into measures directed at prevention and reduction of the risk of sarcopenic obesity in this population subgroup.

Sarcopenia y algunas de sus características más importantes / Sarcopenia and some of its most important features

Introducción: Sarcopenia es la pérdida de masa y potencia muscular, a lo que se suma el pobre desempeño físico. Su padecimiento depende de la genética, del medio ambiente, del proceso natural de envejecimiento y de algunas enfermedades que a veces acentúan su progresión. Objetivo: Describir de forma general algunas de las características más importantes de la sarcopenia. Métodos: Se utilizó como buscador de información científica a Google Académico. Se emplearon como palabras claves: Sarcopenia, envejecimiento, masa muscular y fuerza muscular. Fueron evaluados artículos de revisión y de investigación provenientes de diferentes bases de datos: PubMed, LILACS, Cochrane, SciElo y páginas web, que en general, tenían menos de 10 años de publicados, en idioma español, portugués o inglés, con una adecuada calidad científica y metodológica, según criterio de los autores. Fueron excluidos los artículos que no cumplían con los objetivos del presente trabajo. Esto permitió el estudio de 110 artículos, de los cuales 62 fueron referenciados. Conclusiones: La sarcopenia es un síndrome geriátrico frecuente y relevante. Constituye un serio problema de salud, al aumentar la morbilidad y mortalidad. Es frecuente la adinamia en relación con el declive del funcionamiento físico, fuerza y masa muscular. Para su diagnóstico se debe, al menos, demostrar la reducción de la masa muscular (con Absorsiometría de energía dual de Rayos X o con análisis de la Bioimpedancia), la reducción de la fuerza del apretón de la mano, con dinamómetro y de la función muscular (reducción de la velocidad de la marcha)(AU)

Introduction: Sarcopenia is the loss of muscle mass and strength, added to the poor physical performance. This condition depends on genetics, environment, the natural aging process and of some diseases that sometimes accentuate its progression. Objective: To describe in a general way some of the most important features of sarcopenia. Methods: It was used Google Scholar as scientific information searcher. There were used as keywords: Sarcopenia; aging; muscle mass; muscle strength. There were evaluated review and research articles from different databases as: PubMed, LILACS, Cochrane, SciELO, and web pages, that in general had less than 10 years of being published in Spanish, Portuguese or English language, with an adequate scientific and methodological quality according to the authors criteria. There were excluded the articles that did not meet with the objectives of this work. This allowed the study of 110 articles, of which 62 were referenced. Conclusions: Sarcopenia is a frequent and relevant geriatric syndrome. It is a serious health problem by increasing the morbidity and mortality. It is frequent in it the adynamia in relation to the decline of the physical functioning, the strength and the muscle mass. For its diagnosis, it should be demonstrated at least the reduction of muscle mass (with x-rays dual energy´s absorsiometry or with analysis of the bioelectrical impedance analysis), a reduction in the strength of the grip of the hand with dynamometer, and the muscle function (reduction of speed)(AU)

Sarcopenia, lung disease and mortality: a secondary analysis of the CRELES study / Sarcopenia, doença pulmonar e mortalidade: uma análise secundária do estudo CRELES

AIM: Chronic obstructive pulmonary disease (COPD) is a pro-inflammatory condition leading to wasting states such as sarcopenia. We aimed to describe the effect of COPD and sarcopenia on mortality in Costa Rican older adults in the Costa Rican Longevity and Healthy Aging Study (CRELES). METHOD: This is a secondary analysis of the CRELES, a cohort study consisting of three waves of interviews. For the current study, data from the first and third waves were used. The dependent variable was survival status. COPD and sarcopenia were independent variables. Bivariate analyses were used to compare mortality curves for each group. Association with 3-year mortality was tested with Cox regression models, and hazard ratios (HR) with 95% confidence intervals (CI) were estimated as a measure of the strength of association. RESULTS: Of a total of 2704 participants, 54.29% (n = 1468) were women. Overall mortality was 9.05%. Sarcopenic older adults had the strongest association with mortality (HR = 2.65; 95%CI, 1.81­3.90; p < 0.001), followed by those with both COPD and sarcopenia (HR = 2.59; 95%CI, 1.37­4.92; p = 0.003). The weakest association with mortality was found in patients with neither COPD nor sarcopenia. CONCLUSIONS: The synergistic effect of sarcopenia and COPD has been shown to independently increase mortality in older patients. Our results may be applicable to both Latin American residents and subjects of Hispanic descent living in developed countries. Sarcopenia should be assessed in all patients with COPD since the latter is not a disease limited to the lungs, but rather a systemic disease.

OBJETIVO: A doença pulmonar obstrutiva crônica (DPOC) é uma condição pró-inflamatória que conduz a estados de perda como a sarcopenia. Nosso objetivo foi descrever o efeito da DPOC e da sarcopenia sobre a mortalidade em idosos costa-riquenhos do estudo Costa Rican Longevity and Healthy Aging Study (CRELES). MÉTODO: Esta é uma análise secundária do CRELES, um estudo de coorte composto por três ondas de entrevistas. Para o presente estudo, foram utilizados dados da primeira e terceira ondas. A variável dependente foi o status de sobrevida. DPOC e sarcopenia foram variáveis independentes. Foram realizadas análises bivariadas para comparar as curvas de mortalidade para cada grupo. Testou-se a associação à mortalidade em 3 anos com modelos de regressão de Cox, e razões de risco (HR) com intervalos de confiança (IC) de 95% foram estimadas como medida da força da associação. RESULTADOS: De um total de 2704 participantes, 54,29% (n = 1468) eram mulheres. A mortalidade geral foi 9,05%. Idosos sarcopênicos apresentaram a associação mais forte à mortalidade (HR = 2,65; IC95%, 1,81­3,90; p < 0,001), seguidos por aqueles com DPOC e sarcopenia (HR = 2,59; IC95%, 1,37­4,92; p = 0,003). A associação mais fraca à mortalidade foi encontrada em pacientes sem DPOC e sarcopenia. CONCLUSÕES: Demonstrou-se que o efeito sinérgico da sarcopenia e da DPOC aumenta de forma independente a mortalidade em pacientes idosos. Nossos resultados podem ser aplicáveis a residentes latino-americanos e a descendentes de hispânicos que vivem em países desenvolvidos. A sarcopenia deve ser avaliada em todos os pacientes com DPOC, visto que esta não é uma doença limitada aos pulmões, mas sim uma doença sistêmica.

Prevalence of sarcopenia and its associated factors: the impact of muscle mass, gait speed, and handgrip strength reference values on reported frequencies

OBJECTIVES: Sarcopenia is a common treatable geriatric condition. The aim of this study was to estimate the prevalence of sarcopenia and its associated factors in community-dwelling elderly living in Rio de Janeiro, Brazil, and to discuss the impact of different muscle mass, handgrip strength and gait speed cut-off values on the reported frequency of sarcopenia. METHODS: The health habits, functional capacity, and anthropometric measurements of 745 individuals aged ≥65 years from the Frailty in Brazilian Older People study were analyzed. The participants were classified into the following four groups: no sarcopenia, pre-sarcopenia, sarcopenia and severe sarcopenia. Univariate and multivariate regression analyses were performed. Muscle mass, handgrip strength and gait speed cut-off thresholds tailored to the sample and those proposed by the European Working Group on Sarcopenia in Older People were used to compare the prevalence rates of sarcopenia. RESULTS: Seventy-three percent of the participants were female, 61.9% were Caucasian, and the mean age was 76.6 years. The prevalence rates of sarcopenia were 10.8% and 18% using the sample-tailored and European consensus cut-off values, respectively. Sarcopenia was associated with advanced age (OR: 37.2; CI95%12.35-112.48), Caucasian race (OR: 1.89; CI 95% 1.02-3.52), single marital status (OR:6; CI95% 2.2-16.39), low income (OR:3.64; CI 95% 1.58-8.39), and the presence of comorbidities (OR:3.26; CI 95%1.28-8.3). CONCLUSION: In this study, the estimated prevalence of sarcopenia was similar to that reported in most studies after the tailored handgrip strength and gait speed cut-off values were adopted. A higher prevalence was observed when the cut-off values suggested by the European consensus were used. This indicates that the prevalence of sarcopenia must be estimated using population-specific reference values.

Sarcopenia, obesity and sarcopenic obesity in liver transplantation: a body composition prospective study / Sarcopenia, obesidade e obesidade sarcopênica em pacientes submetidos ao transplante hepático: estudo prospectivo de composição corporal

ABSTRACT Background: Sarcopenia is prevalent before liver transplantation, and it is considered to be a risk factor for morbidity/mortality. After liver transplantation, some authors suggest that sarcopenia remains, and as patients gain weight as fat, they reach sarcopenic obesity status. Aim: Prospectively to assess changes in body composition, prevalence and associated factors with respect to sarcopenia, obesity and sarcopenic obesity after transplantation. Methods: Patients were evaluated at two different times for body composition, 4.0±3.2y and 7.6±3.1y after transplantation. Body composition data were obtained using bioelectrical impedance. The fat-free mass index and fat mass index were calculated, and the patients were classified into the following categories: sarcopenic; obesity; sarcopenic obesity. Results: A total of 100 patients were evaluated (52.6±13.3years; 57.0% male). The fat-free mass index decreased (17.9±2.5 to 17.5±3.5 kg/m2), fat mass index increased (8.5±3.5 to 9.0±4.0; p<0.05), prevalence of sarcopenia (19.0 to 22.0%), obesity (32.0 to 37.0%) and sarcopenic obesity (0 to 2.0%) also increased, although not significantly. The female gender was associated with sarcopenia. Conclusion: The fat increased over the years after surgery and the lean mass decreased, although not significantly. Sarcopenia and obesity were present after transplantation; however, sarcopenic obesity was not a reality observed in these patients.

RESUMO Racional: A sarcopenia é prevalente antes do transplante de fígado e é considerada fator de risco para morbidade/mortalidade desses pacientes. Após o transplante hepático, alguns autores sugerem que a sarcopenia permanece, e os pacientes ganham peso na forma de gordura, atingindo o status de obesidade sarcopênica. Objetivo: Avaliar prospectivamente as mudanças na composição corporal, prevalência e fatores associados em relação à sarcopenia, obesidade e obesidade sarcopênica após o transplante. Métodos: Os pacientes foram avaliados em dois momentos diferentes para composição corporal, 4,0±3,2 e 7,6±3,1 anos e após o transplante. Os dados da composição corporal foram obtidos por meio de bioimpedância elétrica. O índice de massa livre de gordura e o índice de massa gorda foram calculados, e os pacientes foram classificados nas seguintes categorias: sarcopênico; obesidade; obesidade sarcopênica. Resultados: Foram avaliados 100 pacientes (52,6±13,3 anos; 57,0% homens). A prevalência de sarcopenia (19,0% para 22,0%), obesidade (32,0% para 37,0%) e índice de massa livre de gordura (17,9±2,5 para 17,5±3,5 kg/m2), índice de massa gorda aumentou (8,5±3,5 para 9,0±4,0 kg/m2), e obesidade sarcopênica (0 para 2,0%) também aumentaram, embora não significativamente. O gênero feminino foi associado à sarcopenia. Conclusão: Após a operação, a gordura aumentou ao longo dos anos e a massa magra diminuiu, embora não significativamente. A sarcopenia e a obesidade estavam presentes após o transplante; no entanto, a obesidade sarcopênica não foi realidade observada nesses pacientes.

Sex effects on the association between sarcopenia EWGSOP and osteoporosis in outpatient older adults: data from the SARCOS study

ABSTRACT Objective: The objective was to evaluate the association between sarcopenia (EWGSOP) and osteoporosis in older adults. Subjects and methods: This is a cross sectional analysis of a baseline evaluation of the SARCopenia and OSteoporosis in Older Adults with Cardiovascular Diseases Study (SARCOS). Three hundred and thirty-two subjects over 65 years of age were evaluated. Sarcopenia was determined by EWGSOP flowchart and Osteoporosis was established by WHO's criteria. Physical function, comorbidities and medications were evaluated. Results: Women were older (79.8 ± 7.2 years) than men (78.21 ± 6.7 years) (p = 0.042). Osteoporosis occurred in 24.8% of men, and in 42.7% of women (p < 0.001); sarcopenia occurred in 25.5% of men and in 17.7%, of women (p = 0.103). Osteoporosis was diagnosed in 68% of sarcopenic women, however only 20.7% (p = 0.009) of women with osteoporosis had sarcopenia; in older men, 44.7% of individuals with sarcopenia presented osteoporosis and 42.9% (p = 0.013) of men with osteoporosis showed sarcopenia. In an adjusted logistic regression analyses for sarcopenia, osteoporosis presented a statistically significant association with sarcopenia in men [OR: 2.930 (95% CI: 1.044-8.237; p = 0.041)] but not in women [OR: 2.081 (0.787-5.5; p = 0.142)]; in the adjusted logistic regression analyses for osteoporosis, a statistically significant association occurred in men [OR: 2.984 (95% CI: 1.144-7.809; p = 0.025)], but not in women [OR: 2.093 (0.962-3.714; p = 0.137)]. Conclusion: According to sex, there are significant differences in the association between sarcopenia EWGSOP and osteoporosis in outpatient older adults. It is strong and significant in males; in females, despite showing a positive trend, it was not statistically significant.

Prevalência de sarcopenia na Doença Pulmonar Obstrutiva Crônica: revisão sistemática / Prevalência de sarcopenia na Doença Pulmonar Obstrutiva Crônica: revisão sistemática Prevalence of sarcopenia in Chronic Obstructive Pulmonary Disease: systematic review

INTRODUÇÃO: DPOC está associada a um processo inflamatório sistêmico que pode causar sarcopenia, redução da função e massa muscular, embora sua frequência e intensidade não seja completamente conhecida em portadores dessa enfermidade. OBJETIVO: descrever a prevalência e métodos de identificação da sarcopenia na DPOC através de uma revisão sistemática. MATERIAIS E MÉTODOS: Revisão sistemática utilizando a metodologia PICO e palavras-chave (Chronic Obstructive Pulmonary Disease, Sarcopenia). Foram incluídos estudos publicados que estimaram a prevalência de sarcopenia na DPOC. Excluídos aqueles cujo método não detalhou o diagnóstico da sarcopenia. RESULTADOS: A pesquisa resultou inicialmente em 897 artigos. Desses, 877 foram excluídos, sendo 20 selecionados (15 transversais, cinco longitudinais, um caso/controle). As amostras variaram de 57 a 2.582 participantes, a maioria (70%) conduzida em ambulatório. Um estudo foi de base populacional. A idade média foi de 66 anos. A prevalência de sarcopenia na DPOC variou (4,4% a 86,5%). Os métodos diagnósticos utilizados para determinar massa muscular foram o Dual X-ray Absorptiometry, a bioimpedância e as equações de referência. A força muscular foi estimada utilizando-se a preensão manual em dinamômetros portáteis ou a flexão/extensão do joelho através do dinamômetro isocinético. A capacidade funcional foi avaliada pelo teste de caminhada dos seis minutos ou através do teste de velocidade da marcha. CONCLUSÃO: A prevalência de sarcopenia na DPOC encontrada nos estudos (4,4 a 86,5%) é muito variável. Influenciada não somente pela característica do paciente, mas também pelo local, delineamento e método diagnóstico utilizado. Uma padronização de métodos parece ser necessária para se uniformizar condutas na literatura. [AU]

COPD is associated with a systemic inflammatory process that can cause sarcopenia, reduced function and muscle mass, although its frequency and intensity is not completely known in patients with this disease. OBJECTIVE: To describe the prevalence and methods of identifying sarcopenia in COPD through a systematic review. METHODS AND MATERIALS: Systematic review using the PICO methodology and keywords (Chronic Obstructive Pulmonary Disease, Sarcopenia). We included published studies that estimated the prevalence of sarcopenia in COPD. Excluding those whose method did not detail the diagnosis of sarcopenia. RESULTS: The search resulted initially in 897 articles. Of these, 877 were excluded, of which 20 were selected (15 transverse, five longitudinal, one case / control). Samples ranged from 57 to 2,582 subjects, the majority (70%) conducted on an outpatient basis. One study was population-based. The mean age was 66 years. The prevalence of sarcopenia in COPD varied (4.4% to 86.5%). The diagnostic methods used to determine muscle mass were Dual X-ray Absorptiometry, bioimpedance and reference equations. Muscle strength was estimated using manual gripping on portable dynamometers or knee flexion / extension through the isokinetic dynamometer. Functional capacity was assessed by the six-minute walk test or gait speed test. CONCLUSION: The prevalence of sarcopenia in COPD found in the studies (4.4 to 86.5%) is very variable. Influenced not only by the patient's characteristic, but also by the location, design and diagnostic method used. A standardization of methods seems to be necessary to standardize conducts in the literature. [AU]
