Abstract

Objective:To assess reproducibility and validity of resting metabolic rate (RMR) of Bangladeshi women as measured with the MedGem device and using the Deltatrac metabolic monitor as a reference; and (2) to evaluate the FAO/WHO/UNU basal metabolic rate (BMR)-prediction equations. Design:In each of two sessions, resting oxygen consumption was measured in triplicate by MedGem and in triplicate by Deltatrac device. Setting:Matlab area, the rural field research area of the Centre for Health and Population Research, Bangladesh (ICDDR,B). Subjects:A total of 37 nonpregnant, nonlactating women, aged 27.64.5 y, BMI 20.83.1 kg/m2 participated. Results:The difference in oxygen consumption by MedGem and Deltatrac device was significantly level dependent. Within-subject within-session variations (expressed as CV) were 9.0 and 3.0% (P
