The purpose of this study was to determine the accuracy of self-reported dietary intake in MHD patients to explain the contradiction of weight stability despite their reported insufficient energy expenditure (EI). Data for this study were collected as part of a 92-day randomized, double-blind, controlled, metabolic nitrogen balance study designed to determine the protein requirements of 13 MHD patients.

Findings were as follows: Mean EI:measured resting energy expenditure (REE) and EI:estimated and adjusted total energy expenditure ratios were significantly less than their respective cut-off values suggesting that subjects in this study underreported energy intake. Mean kcals reported in the 3-day food records were significantly different than mean kcals recommended by the National Kidney Foundation. There was no significant difference between the mean predicted and mean measured REE in this group of MHD subjects, and the mean EI:measured REE ratio for dialysis and non-dialysis days.
