STUDY ON ENERGY METABOLISM IN SIMP LE OBESE CHILDREN / 营养学报

ABSTRACT

Objective: The energy intake and energy expenditure were measured in order to observe the variation of energy metabolism in simple obese children and provide evidences for further research of etiology, prevention and control of obesity in children. Methods: Basic metabolic rate(BMR), resting metabolic rate (RMR) and energy expenditure of standardized cycling were measured by using open-circuit indirect calorimetry in 54 obese children and 60 nonobese children in a full-time boarding school in Guangzhou suburb. Total energy expenditure (TEE) was estimated by time record of activities and factorial approach. Dietary intake was surveyed by weighing method. Results: When expressed as kJ/h, BMR,RMR, energy expenditure of standardized cycling were significantly higher(P
