Percentage body fat determination in hemodialysis and peritoneal dialysis patients: a comparison.
OBJECTIVE
To evaluate percentage body fat in hemodialysis (HD) and peritoneal dialysis (PD) patients.


METHODS
A prospective study of 20 HD patients and 20 PD patients.


METHODS
Sol Goldman Renal Therapy Center, Lenox Hill Hospital, New York, NY; Baumritter Kidney Center Albert Einstein College of Medicine, Bronx, NY; Body Composition Unit, St Luke's Roosevelt Hospital, Columbia University, New York, NY.


METHODS
Twenty HD (10 men, 10 women) patients, mean age 41.8 +/- 2.4 years and 20 PD (12 men, 8 women) patients, mean age 48.6 years +/- 3.0 years.


METHODS
This is a noninterventional study. PATIENTS signed consent to undergo dual-energy x-ray absorptiometry, total body potassium counting bioelectrical impedance analysis, total body water determination, and anthropmetric evaluation.


METHODS
Present and compare percentage body fat between HD and PD patients as determined by the methods used.


RESULTS
Percentage fat is not different between HD and PD patients. Differences in absolute values of percent fat between techniques exist.


CONCLUSIONS
HD patients and PD patients may be evaluated by the methods of body composition used. Percentage body fat will vary among techniques; therefore the same method should be used to follow a patient over time.
