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 27.6±4.5?y, BMI 20.8±3.1?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<0.01) and within-subject between-session variations were 8.2 and 4.5%(P<0.01) for MedGem and Deltatrac, respectively. Mean RMR measured by Deltatrac (5.17±0.51?MJ/day) was not significantly different from the BMR predicted by the FAO/WHO/UNU equations (5.16±0.42?MJ/day) in the second session and only 0.19?MJ/day higher than predicted in the first session (P<0.05). CONCLUSION:: Reproducibility and validity of the MedGem device was poor compared to the Deltatrac reference method. The FAO/WHO/UNU BMR-prediction equations give a good estimation of the BMR of rural, nonpregnant, nonlactating Bangladeshi women of 18-35?y.
