Evaluación del gasto energético y actividad física en escolares eutróficos, con sobrepeso u obesidad

摘要

Physical inactivity has been identified as a major cause of overweight and obesity in children. Objective: To determine and compare the intensity of physical activity and energy expenditure in eutrophic (E) and overweight/obese (OW) children. Patients Method: 37 school children 6 to 9 years old, 15 overweight (OW) and 22 eutrophic (E) were studied with Actihearts? monitors. Nutritional status was classified according to body mass index (BMI). Resting metabolic rate (RMR), total energy expenditure (TEE) and physical activity level (PAL) was calculated. Actihearts? monitors were used to record heart rate (HR), physical activity energy expenditure (PAEE), time spent in physical activity (TPA) and accelerometry (AC). Results: OW children reported a RMR = 1,275 kcal/d ± 164,2; TEE = 2,316 kcal/d ± 358,7; PAEE = 985 kcal/d ± 223,1; PAL = 1,82 ± 0,13; significantly higher (p
