OBJECTIVE: The aim of the study was to determine the energy expenditure and estimate the energy intake of children and adolescents with post-infectious bronchiolitis obliterans and compare them with those of healthy children and adolescents. METHODS: This cross-sectional study included 36 children and adolescents with bronchiolitis obliterans aged 8 to 18 years, and a control group with 36 healthy individuals matched for sex, age and body mass index. Anthropometric data were collected from all individuals. Energy expenditure was determined by indirect calorimetry, activity factor was estimated by a 24-hour record of physical activities, and energy intake was estimated by the 24-hour food recall. RESULTS: Data for the bronchiolitis obliterans and control groups are, respectively: body mass index of M=18.9, SD=4.0kg/m² and M=18.8, SD=3.4kg/m²; resting energy expenditure of M=1717.6, SD=781.5kcal/day and M=2019.9, SD=819kcal/day; total energy expenditure of M=2677.5, SD=1514.0kcal/day and M=3396.1, SD=1557.9kcal/day; estimated energy intake of M=2294.1, SD=746.7kcal/day and M=2116.5, SD=612.1kcal/day. Resting energy expenditure (p=0.102) and total energy expenditure (p=0.051) did not differ between the groups, even when adjusted for lean mass. Total energy expenditure and intake of the bronchiolitis obliterans group did not differ significantly (p=0.202). Energy intake by the control group was lower than expected according to their total energy expenditure (p<0.001). CONCLUSION: The resting energy expenditure and total energy expenditure of the two groups were similar. The estimated energy intake of the control group was lower than their total energy expenditure. The bronchiolitis obliterans group had an appropriate energy balance.
