Characteristics in Nutritional Status of Patients on Hemodialysis and Continuous Ambulatory Peritoneal Patients in Chonbuk Area

ABSTRACT

The present study was designed to compare the nutritional status of hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) patients. Subjects were 58 HD patients (male/female = 29/29) and 33 CAPD patients (male/female=23/10) undergoing dialysis treatment in Artificial Kidney Unit of Chonbuk National University Hospital. For nutritional assessment, %IBW (ideal body weight), %TSF (tricep skin fold), %MAC (mid arm circumference), %MAMC (mid arm muscle circumference), serum albumin, serum transferrin, TLC (total lymphocyte count), SGA (subjective global assessment) and estimated energy and protein intakes by 1-month food frequency method were used. Between HD and CAPD group, mean age (50+/-12 vs. 52+/-12 yr), dialysis durations (37+/-36 vs. 30+/-26 mon), dietary energy intakes (28.3+/-9.0 vs. 28.8+/-8.6 kcal/kg/day), dietary protein intakes (1.1+/-0.4 vs. 1.2+/-0.3 g/kg/day) and incidence of co-morbid conditions (69.0% vs. 69.7%) were not significantly different. Data by using SGA showed a higher incidence of malnutrition in CAPD patients (45.6%) than in HD patients (36.2%). %IBW (p<0.001), %TSF (p<0.001) and %MAC (p<0.001) were higher in CAPD patients than were in HD patients. But serum albumin (p<0.001) and transferrin (p<0.001) were significantly lower in CAPD patients than were in HD patients. A higher incidence of malnutrition was shown in CAPD Patients than in HD Patients due to different dialysis type. A significant finding was that CAPD showed protein deficient malnutrition and HD did calorie deficient malnutrition. It suggests that an adequate dietary intake considering dialysis type prevents a prevalence of malnutrition.
