      Abstract

      Introdução: A doença renal crônica (DRC) interfere diretamente na capacidade funcional, na independência e, consequentemente, na qualidade de vida (QV). Objetivo: Comparar a capacidade funcional e a qualidade de vida de doentes renais crônicos em hemodiálise (G1) e pré-dialíticos (G2). Métodos: Estudo transversal descritivo, 54 pacientes com DRC, 27 do G1 (58,15 ± 10,84 anos) e 27 do G2 (62,04 ± 16,56 anos). Verificaramse os fatores de risco cardiovasculares, medidas antropométricas, força muscular respiratória verificada por meio da pressão inspiratória (PImax) e expiratória (PEmax) máximas, teste de caminhada de seis minutos (TC6'), teste cardiopulmonar de exercício, teste de sentar e levantar de um minuto (TSL1') e o Short-Form Questionary (SF-36) para avaliar a QV. Os pacientes apresentavam estadiamento da doença entre 2 a 5. Realizou-se o teste de normalidade Kolmogorov-Smirnov e utilizou-se o teste t (Student) ou o teste U (Mann Whitney) para a comparação das médias das variáveis quantitativas e o teste de Quiquadrado de Pearson e exato de Fischer para as variáveis qualitativas. Para identificar as correlações, foi utilizado o teste de Pearson ou de Spearman. Resultados: Não foi encontrada diferença estatisticamente significativa entre G1 e G2, no VO2pico (p = 0,259), no TC6' (p = 0,433), na PImax (p = 0,158) e somente foi encontrada diferença na PEmax (p = 0,024) para G1. Os escores do questionário SF-36 mostram em ambos os grupos um pior estado de saúde evidenciada pela pontuação baixa nos escores de QV. Conclusão: Os pacientes com DRC apresentaram reduzida capacidade funcional e QV, sendo que a hemodiálise não demonstrou estatisticamente ter repercussão negativa quando comparados com os pacientes pré-dialíticos.

      Introduction: Chronic kidney disease (CKD) infers directly in functional capacity, independence and therefore quality of life (QOL). Objective: To compare the physical fitness and quality of life of patients with chronic kidney disease submitted on hemodialysis (G1) and predialysis treatment (G2). Methods: A cross-sectional study, 54 patients with CKD, 27 of the G1 group (58.15 ± 10.84 years), 27 of G2 group (62.04 ± 16.56 years). There were cardiovascular risk factors, anthropometric measurements, respiratory muscle strength was measured by the inspiratory pressure (MIP) and expiratory (MEP) maximum measured in the manometer, six-minute walk (TC6'), cardiopulmonary exercise test, sit and stand one minute test (TSL1') and the Short-Form Questionary (SF-36) to assess QOL. The patients presented disease of stage between 2 and 5. It was applied the Kolmogorov-Smirnov normality test and used the t (Student) test or the U (Mann Whitney) test to compare the means of quantitative variables and the chi-square Pearson test and Fisher's exact test for qualitative variables. Pearson's or Spearman's test was used to identify correlations. Results: No statistically significant difference was found between G1 and G2 in VO2peak (p = 0,259) in TC6' (p = 0,433) in the MIPmáx (p = 0,158) and found only in the MEPmáx (p = 0,024) to G1. The scores of the SF-36 in both groups showed a worse health status as evidenced by the low score in scores for QOL. Conclusion: Patients with CKD had reduced functional capacity and QOL, and hemodialysis, statistically, didn't have showed negative repercussions when compared with pre-dialysis patients.
