Background : Protein-energy wasting is a significant problem in End stage renal disease (ESRD) patients. Furthermore, it
compromises the patient’s Quality of life (QOL). Multifrequency Bioimpedance Spectroscopy (BIS) is a validated method
to assess body composition in dialysis patients. There has been no data on the relationship between body composition and
QOL in ESRD patients who were treated with different modalities.
Objective : To explore the association between body composition as assessed by BIS and QOL in ESRD patients who received
different treatment modalities.
Material and Method: The present study is a cross sectional, descriptive analytic study of the association between QOL
and BIS in ESRD patients in Burapha University, Chonburi, Thailand. QOL was assessed by WHOQOL-BREF questionnaire,
body composition was measured by BIS technique. The difference between groups was tested by one-way ANOVA test,
relationship between groups was tested with Pearson correlation test.
Results : Eighteen predialysis-CKD5, 26 peritoneal dialysis (PD), and 34 hemodialysis (HD) patients were included in the
present study. All PD patients had weekly Kt/V ≥1.7 per week and all HD patients had weekly Kt/V ≥3.6 per week. There
were no statistically difference in baseline characteristics including Charlson comorbidity index, dietary intake, BMI, and
blood pressure between groups. Mean QOL scores in each group were in the middle range and not significantly difference.
PD patients had more over hydration when compare to HD patients (16.1811.24 vs. 2.3611.07 %OH/ECW p<0.0001).
There were inversed correlation between overhydration and physical health in HD patients (r = -0.372, p = 0.033) but not
in PD and CKD5 patients. CKD5 patients had more lean tissue index (LTI) than PD and HD patients (LTI = 14.343.13,
12.263.65, 11.483.48 kg/m2 respectively, p = 0.023). There were correlation between LTI and overall QOL in CKD5
(r = 0.690, p = 0.002) and PD patients (r = 0.498, p = 0.010). In HD patients, LTI was associated with better physical
health (r = 0.464, p = 0.007).
Conclusion : QOL in predialysis-CKD5, PD and HD patients were not statistically different. HD patients had better volume
control than PD patients. Higher LTI were associated with better QOL in ESRD patients.
