title: [Comparative study of total energy expenditure estimated by Sense Wear Armband and Harris-Benedict equation in healthy ambulatory population; utility in clincal practice].
abstract: BACKGROUND
  Different methodologies for estimating total energy expenditure (TEE) are currently used.
  
  
  OBJECTIVE
  To know which tool is most useful to estimate TEE in healthy subjects: SenseWearArmband (SWA) or Harris-Benedict (HB).
  
  
  METHODS
  Cross-sectional study in 32 volunteers. SWA was placed for 24 hours and TEE was estimated with HB and the activity factor calculated with a 24-h activity questionnaire.
  
  
  RESULTS
  The difference between both estimates of TEE was 351.9 (95% CI 222.2 to 481.6) kcal/day (p < 0.001). This difference was associated with obesity, but not with sex. The value of ICC was 65.0% (95% CI 7.8% to 86.2%) being statistically significant (p < 0.001). There was a significant difference in the estimation of the activity between both techniques [0.4 (CI 95% 0.1 to 0.7) hours (p = 0.007)].
  
  
  CONCLUSIONS
  A significant difference in the estimation of TEE using HB and SWA has been found.
