Actual (reported)Patients with kidney disease need accurate advice on their diet. Researchers know very little about energy needs and nutritional requirements in kidney patients. Simple tools are needed to calculate calorie requirements so that good bed-side advice can be given to patients, and to allow cost-effective research. This study aimed to measur energy requirements in kidney disease using a gold-standard safe and very accurate method called the "doubly labelled water technique". The study has compared measurements with less costly measurements obtained using a device which measures oxygen content of air breathed out. The study has also measured physical activity levels with questionnaires.

Actual (reported)Energy expenditure using doubly labelled water
14 days
Whole body bioimpedance
1 day
Resting Energy Expenditure using indirect calorimetry
1 day
Stanford 7 day recall questionnaire physical activity level
7 days
40 patients with CKD stage 1-3. All subjects performed a comprehensive metabolic analysis including measurement of Resting Energy Expenditure using indirect calorimetry, bioimpedance, doubly-labelled water technique and body size measures. Physical activity was assessed using a Stanford 7 day recall questionnaire.
40 patients with CKD stage 4-5. All subjects performed a comprehensive metabolic analysis including measurement of Resting Energy Expenditure using indirect calorimetry, bioimpedance, doubly-labelled water technique and body size measures. Physical activity was assessed using a Stanford 7 day recall questionnaire.
Resting energy expenditure represents the amount of calories required for a 24-hour period by the body during a non-active period.
