ObjectiveThis study compared the energy expenditure measured by indirect calorimetry with that estimated by prediction equations in asthmatic and non-asthmatic adolescents.MethodsThis was a cross-sectional study with 69 adolescents aged 10 to 18 years. Three paired groups were compared (overweight, asthmatic adolescents, normal weight, asthmatic adolescents and overweight, non-asthmatic adolescents). Energy expenditure was estimated by indirect calorimetry and prediction equations.ResultsEach group consisted of 23 adolescents (10 females), with an average age of M=12.4, SD=2.4 years. In the group of overweight, asthmatic adolescents, the resting energy expenditure was M=1550.2, SD=547.2kcal/day; in the group of normal weight asthmatic adolescents, the resting energy expenditure was M=1540.8, SD=544.2kcal/day; and in the group of overweight, non-asthmatic adolescents, the resting energy expenditure was M=1697.2 SD=379.8kcal/day. The results were similar among groups even when adjusted for lean and fat mass (f=0.186; p=0.831). The total energy expenditure was also similar among groups, except that the Harris-Benedict formula underestimated the energy expenditure in normal weight asthmatic adolescents and overweight, non-asthmatic adolescents.ConclusionThe resting energy expenditure was not statistically different among groups of asthmatic and non-asthmatic adolescents, even when adjusted for lean mass and fat mass. For all three groups, the predictive equations were useful for estimating the resting energy expenditure and total energy expenditure.
