Gasto energético e consumo calórico em adolescentes do sexo masculino com diferentes níveis de adiposidade corporal

Abstract

Energy expenditure and caloric intake were compared among adolescents with different levels of adiposity. A cross-sectional study was carried with 40 adolescent boys aged 14 to 16 years. The adolescents were divided into two groups of 20 subjects each, according to % body fat (%BF): low (< 11%) and high (> 20%). Energy expenditure was measured using accelerometer and daily activity diary. The dietary pattern was evaluated based on 24-h recall. Caloric intake was lower in adolescents with low %F (X = 2408.1 ± 557.9 kcal.day-1) compared to those with high %F (X = 2931.7 ± 679.2 kcal.day-1, p<0.05). In addition, they presented greater relative energy expenditure than adolescents with high %F (p<0.05). High %F adolescents showed larger caloric intake than expenditure, while the opposite was observed among low %F males.
