TI  - Energy expenditure in preadolescent African American and white boys and girls: 
      the Baton Rouge Children's Study.
PG  - 705-13
AB  - BACKGROUND: Low energy expenditure has been identified as a potential risk factor 
      for body fat gain. OBJECTIVE: The objective was to determine the relations 
      between race, sex, body fat, and energy expenditure. DESIGN: As part of the Baton 
      Rouge Children's Study, energy expenditure was examined in 131 preadolescent 
      African American and white girls and boys, further stratified as obese or lean. 
      Total daily energy expenditure (TDEE) was measured by the doubly labeled water 
      method. Resting metabolic rate (RMR) and the thermic effect of food were measured 
      by indirect calorimetry. Fat-free mass and fat mass were measured by dual-energy 
      X-ray absorptiometry. To account for differences in body size, energy expenditure 
      variables were adjusted with the use of fat-free mass or fat-free mass and fat 
      mass as covariates. RESULTS: The African American children had lower TDEE and RMR 
      than did the white children. A lower level of energy expended in physical 
      activity by the African American girls and a lower RMR in the African American 
      boys accounted for the racial differences in TDEE. The white boys had a higher 
      RMR than did the white girls. The girls had a lower TDEE and expended less energy 
      in activity than did the boys. Energy expended in activity was lower in the obese 
      children. CONCLUSIONS: The African American children expended less energy than 
      did the white children. The obese children spent less time engaged in activity or 
      engaged in lower-intensity activity. Obese children may maintain their obese 
      state by spending less time in physical activity, but they do not have a reduced 
      RMR or thermic effect of food.
