A Comparison of Calculated Energy Requirements to Measured Resting Energy Expenditure in HIV-1-Infected Subjects

HIV-infected individuals are particularly susceptible to nutritional changes, such as weight loss and malnutrition. To compare calculated energy need of HIV-infected patients to measured energy consumption, researchers studied 20 HIV- positive patients. The subjects, who were part of clinical drug trials conducted by the National Institute of Allergy and Infectious Diseases, underwent indirect calorimetry measurements. Energy requirements for the subjects were also calculated using the Harris Benedict Equation (HBE), a multiparameter linear regression formula for calculating resting energy expenditure. The findings suggest that calculating energy expenditure for HIV-infected people using a standard formula such as HBE consistently underestimates actual energy expenditure in this population.
