Análise da sarcopenia e a sua associação com indicadores clínicos, funcionais e de qualidade de vida em pessoas idosas atendidas no ambulatório do hospital Universitário João de Barros Barreto

Abstract

Introduction: Introduction: Ageing can be accompanied by a progressive decline in muscle mass, strength and function. This resulting health condition is known as sarcopenia, a muscle disease that develops progressively and chronically. Age-related sarcopenia has several factors that accelerate this process and need to be identified and controlled in order to promote a good health prognosis and quality of life for the elderly population. Objective: To assess the association between sarcopenia and functional and quality of life indicators in elderly people treated at the geriatrics outpatient clinic of the João de Barros Barreto University Hospital (HUJBB). Methods: This is an observational, analytical, cross-sectional study carried out at the HUJBB geriatrics outpatient clinic. Sociodemographic and clinical assessments were carried out: sarcopenia assessment (SARC-Calf, handgrip strength assessment, Tetrapolar Electrical Bioimpedance (BIA) and Short Physical Performance Battery (SPPB)), functional indicators assessment (Barthel, quadriceps strength assessment, physical activity level assessment (IPAQ) and presence of falls in 60 days) and quality of life assessment (SF-12). The algorithm of the European Working Group on sarcopenia in the elderly (EWGSOP2) was used. Results: 129 participants were assessed (73% women, p = 0.001), with a mean age of 75.4 years and from the capital (80.6%). 57% were found to be at risk of sarcopenia, with a prevalence of sarcopenia of 27.1%. Handgrip strength (HGS) 18kg/f, skeletal muscle mass 18.3kg; SPPB 9 points; Barthel score 58.8% of independent participants; quadriceps strength 14kg/f; IPAQ 38.8% with a low level of physical activity and SF-12 37.7 points for the physical component and 48.2 points for the mental component. There was an association between appendicular skeletal muscle mass (ASMR) and calf circumference (WC), age, SARC-Calf, FPM and quality of life (physical component) for men (adjusted R2 0.42 and p<0.05), as well as sarcopenia, classified by ASMR, with BIA variables: body resistance, total body water in lean mass, lean mass and basal metabolic rate for men (adjusted R2 0.49 and p<0.05), and for women, intracellular water and total body water in body weight (adjusted R2 0.60 and p<0.05). Conclusion: This study concludes that WC, age, sarcopenia risk screening, HGS and quality of life were associated with MMEA measured by BIA. For the diagnosis of sarcopenia, there were different associations between the BIA markers when adjusted for gender.
