An evaluation of the sensitivity and specificity of energy expenditure measured by heart rate and the Goldberg cut-off for energy intake: basal metabolic rate for identifying mis-reporting of energy intake by adults and children: a retrospective analysis

Objective: To identify adults and children as under- (UR), acceptable (AR), or over-reporters (OR) of energy intake (EI) using energy expenditure measured by doubly labelled water (DLW) (EEDLW), and to use this as a reference to determine the sensitivity and specificity of (i) EE measured by heart rate (EEHR), and (ii) the Goldberg cut-off technique for classifying subjects into the same categories.
