Level of Physical Activity and functional capacity of patients with pre-dialytic chronic kidney disease and in hemodialysis

ABSTRACT The aim of this study was to compare the functional capacity (FC) and level of physical activity (LPA) of individuals with chronic kidney disease (CKD) in long-term hemodialysis (HD) treatment (G1); in short-term HD treatment (G2); in conservative treatment (G3), and individuals without CKD (G4). This was a descriptive cross-sectional study with a convenience sample. A total of 44 individuals were evaluated, 13 of G1 (50.6 ± 11.5 years), 9 of G2 (50.8 ± 19.01), 9 of G3 (42.8 ± 15.6), and 13 of G4 (49 , 2 ± 11.2). FC was assessed by the six-minute walking test (6MW) and the L PA by the IPAQ questionnaire. For statistical analysis in the comparison between groups, we used ANOVA One-way with Bonferroni post hoc. For categorical variables, the Chi-square test was used. A significant difference was found in the comparison of the 6MW walking distance between G1 and G4 (409.4 ± 108.1 x 571, 9 ± 31.5m; p = 0.001) and between G2 and G4 (422.6 ± 133.2 x 571.9 ± 31.5 m, p = 0.006). Similar results were observed for 6MW distance in prediction percentage. Regarding LPA, no significant differences were found between the groups and most individuals presented low levels. Therefore, it was concluded that individuals with CKD in HD treatment present reduction of CF when compared to people without CKD.
