Abstract Objective To determine the accuracy of basal metabolic rate (BMR) equations in predicting basal metabolic rates of Chinese adolescents. Methods Twentytwo participants aged 14－18 years were enrolled. The predicted BMRs were gained by revised HarrisBenedict equation, KathMcArdle equation, Henry equation, Schofiled1 equation, Schofield2 equation, World Health Organization (WHO) equation, Muller equation, Herman equation, and Tverskaya equation. BMRs were measured in a 24hour activity cycle in a metabolic chamber. Then, the difference and agreement were evaluated between the measured values and predicted values. Results There were no significant differences between the predicted values of the revised HarrisBenedict and Tverskaya equations and the measured values in male adolescents(P>0.05). There were no significant differences between the predicted values of KathMcArdle, Tverskaya, and Muller equations and the measured values in female adolescents(P>0.05). However, there was no agreement between measured values and predicted values by all equations according to the equivalence test. Conclusion The accuracy of the BMR predictive equation established by fatfree body mass indicator is better than the BMR predictive equation established by indicators such as height, body mass, and age. The BMR predicted values of all equations are in poor agreement with the measured values. In the future, it is necessary to establish predicted equations of BMR for Chinese adolescents based on a large sample population.
