Abstract
Purpose
The aim of this study was to investigate the association between fatigue and phase angle (PA) in patients with chronic kidney disease (CKD) on hemodialysis (HD).
Methods
A cross-sectional study with older patients than 18 years diagnosed with CKD undergoing HD. From 160 (58.36±15.05 years) patients, (n=96; 60%) are men. Body mass and height were assessed using a portable scale and stadiometer, followed by body mass index (BMI) calculus. The bioimpedance electrical analysis was performed using the Bodystat QuadScan 4000. The sample size was dichotomized in two groups, using the median of our sample, either normal when PA ≥5.4°, or low when the PA <5.4°. The Chalder fatigue questionnaire was used the assess the fatigue. The multiple regression was applied to assess the association between fatigue questionnaire and PA.
Results
Were considered normal PA≥5.4° (n=78, 48.8%) and low PA<5.4° (n=82, 51.2%). The patients of the PA<5.4° group are older compared to the PA≥5.4° group (63.1±15.1 vs. 53.3±13.4 years, p<0.001). There was no association between PA and fatigue score in the crude model (OR: 1.02, 95%CI: 0.96–1.08, p=0.47) and after confounding variables (OR: 1.03, CI: 0.95–1.12, p=0.43).
Conclusions
In HD patients, we found that patients with lower PA values are older. In addition, we did not find association between fatigue and PA.
