Risco de sarcopenia e qualidade de vida nos pacientes renais crônicos em hemodiálise

Abstract

Background: Sarcopenia and low quality of life (QOL) are widely found among hemodialysis (HD) patients. We aimed to verify whether risk of sarcopenia can predict QOL level in these patients. Methods: The sample was formed by 147 chronic kidney disease patients undergoing HD in October 2020 at a single dialysis center. Demographic and clinical data were collected. Risk of sarcopenia was classified using the SARC-F questionnaire. QOL was evaluated by the Brazilian version of the SF-36. QOL scores were compared between patients with and without risk of sarcopenia. Multivariate linear regression was performed to test risk of sarcopenia as an independent predictor of QOL scores. Results: There were 62 (42.2%) patients with risk of sarcopenia. In the comparison of QOL scores between patients with and without risk of sarcopenia, scores of seven dimensions were significantly lower among patients with sarcopenia risk, the only exception being role-emotional. Risk of sarcopenia was an independent predictor of six dimensions of QOL, except for role-emotional and mental health. Conclusion: We found risk of sarcopenia to be an independent predictor of QOL among HD patients. Our results point to the possibility of improving patients’ QOL by intervening to minimize the risk of sarcopenia.
