Energy Requirement of Patients Undergoing Hemodialysis: A Cross-Sectional Study in Multiple Centers

Table 3

Factors correlated with resting energy expenditure (REE) and total energy expenditure (TEE) in hemodialysis patients.

Dry weight (kg)	0.54	<0.001	0.54	<0.001
BMI (kg/m^2)	0.38	<0.001	0.37	<0.001
Serum creatinine (mg/dL)	0.28	<0.001	0.29	<0.001
Sex	0.24	<0.001	0.26	<0.001
Insulin (IU)	0.17	0.04	0.18	0.03
GNRI	0.21	0.01	0.23	0.01
Sarcopenia	−0.39	0.002	−0.38	0.002
Age (years)	−0.36	<0.001	−0.36	<0.001
Kt/V	−0.31	<0.001	−0.31	<0.001
nPNA	−0.15	0.228	−0.16	0.212
Diabetes	−0.04	0.773	−0.04	0.745

BMI: body mass index, GNRI: geriatric nutritional risk index, Kt/V: dialysis treatment adequacy (dialyzer clearance of urea × dialysis time)/volume of distribution of urea, approximately equal to a patient’s total body water.
