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.
