1
DER, dietary energy requirement; DRI, Dietary Reference Intake; KDOQI, Kidney Disease Outcomes Quality Initiative; REE, resting energy expenditure.
2
Measured by indirect calorimetry.
3
Estimated from KDOQI guidelines (31).
4
DERs of normal sedentary adults aged ≥19 y according to the DRIs (24).
5
Estimated by using the model B equation, derived from the data in Redman et al. (25); the equation includes body-composition measurements to predict DER and was used because of its higher coefficient than model A. Model B: Total daily energy expenditure (kcal/d) = 454+38.7 × fat-free mass (kg) − 5.4 × fat mass (kg) + 4.7 × age (y) + 103 × sex (1 = female, 0 = male).
6
95% CI of the mean.
