Dietary Evaluation and Protein Catabolic Rate in Maintenance Hemodialysis Patients
|
|
|
|
|
Abstract
|
|
|
As various metabolic alterations develop in uremic patients. their diets to be restricted. Furthermore. Medical complications with acompanying anorexia result in further complications and decrease in body strength.
To assess the nutritonal status of hemodialyzed patients. we performed evaluation for dietary intake was estimated by 3-day food record method. And PCR was calculated with blood urea nirogen at pre and post
hemodialysis.
@ES The results were s follows;
@EN 1) Average daily energy and protein intake were 26.7±5.1 kcal/kg of body weight 0.95±0.19 g/kg of body weight, respectively.
2) Protein catabolic rate calculated from interdialysis blood urea nitrogen levels was 1.00±0.20 g/kg ofbody weight. Protein catabolic rate was correlated with the amount of Protein intake(r=0.44, p<0.05).
3) Relative body weight(RBW) of the subjects was smaller than that of healthy man without hemodialysis. Calorie and protein intake and protein catabolic rate were significantly different (p<0.05) between patients with lower RBW(<90% of ideal
body
weight) and those with normal RBW(90~110% of iedal body weight).
4) The duration of hemodialysis did not have a significant effect on the nutritional status of the subjects.
