RESUMO:

Sarcopenia is a progressive and generalized muscle disorder with the reduction of muscle strength as the main diagnostic parameter. However, there are a few studies that assess the prevalence of sarcopenia with the new European consensus (EWGSOP2) as well as the investigation of indicators that identify it more quickly, simply and at low cost. Thus, the aim of this study was to determine the prevalence of sarcopenia and associated factors and to evaluate the phase angle as a diagnostic method for sarcopenia. This is a cross-sectional study carried out with elderly women in the community. Sarcopenia was defined according to the EWGSOP2 algorithm, muscle strength was assessed by handgrip strength, muscle mass by bioimpedance and performance by walking speed. Sociodemographic characteristics, lifestyle, health and nutritional status were considered independent variables to determine the factors associated with sarcopenia. The phase angle was obtained by tetrapolar electrical bioimpedance. It was observed that the prevalence of sarcopenia was 12.3%, probable sarcopenia of 13.5% and severe sarcopenia of 6.4%. Most elderly women with sarcopenia were older than 70 years, had an inadequate BMI (underweight, overweight or obesity) and adequate waist and calf circumferences. Sarcopenia was associated with age (OR: 12.80; 95% CI: 3.56 - 46.09), physical activity (OR: 3.45; 95% CI: 1.23 - 9.63), circumference calf (OR: 5.15; 95% CI: 1.56 - 14.32) and waist circumference (OR: 0.20; 95% CI: 0.06 - 0.62). It was found that the cutoff point of the phase angle to identify sarcopenia was ≤ 5.15 °, with an area under the ROC curve of 0.685 (95% CI: 0.571-0.800) sensitivity of 81.0%, specificity of 60.8% and accuracy of 63.31%. Elderly women with reduced phase angle were more likely to have reduced muscle mass (OR: 2.53; 95% CI: 1.18 - 5.50) and sarcopenia (OR: 4.69; 95% CI: 1.44 - 15.25). Thus, it was found that the prevalence of sarcopenia in elderly women in the community using the EWGSOP2 consensus definition was significant, and associated with age, physical activity and waist and calf circumferences. In addition to the phase angle, it can be used as an indicator for screening elderly women with sarcopenia.
