title: [Evaluation of total energy expenditure in adult, overweight and free-living subjects. A comparison between two methods: Factorial Method vs SenseWear Armband "Metabolic Holter"].
abstract: OBJECTIVE
  Evaluation of SenseWear Armband functional and structural characteristics and comparison between TEE value from Factorial Method and Metabolic Holter.
  
  
  METHODS
  The study has involved a homogeneous group of 21 adult, overweight (25BMI30 Kg/m(2)) and free-living subjects, 9 men and 12 women, with an average age of 34.9 +/- 14.5 (20-60 years old). TEE valuation has been performed for each subject by means of Factorial Method and, secondly, through the application of SenseWear Armband (Bodymedia Inc., Pittsburgh, PA, USA).
  
  
  RESULTS
  Values recorded by Armband overestimate Factorial values of 14%. The Student's t Test has reported significant results (t = 3.540; p = 0.002). Spearman's Correlation has showed the following values of r = 0.696 and p = 0.001.
  
  
  CONCLUSIONS
  The analysed methods can't be superimposed because the study has showed a signifi cant difference between the reported values. In spite of all that, Spearman study has highlighted a remarkable statistic relation between the techniques. In conclusion, SWA and FM seem to allow a corresponding diagnosis.
