title: [Comparison between subjective and objective methods for sodium intake estimate among hypertensive persons].
abstract: BACKGROUND
  High sodium intake contributes to arterial hypertension; the relationship between high blood pressure and human aging is stronger among populations with high sodium intake.
  
  
  OBJECTIVE
  The aim of this research is to compare subjective and objective methods on the estimate of the consumption of sodium.
  
  
  METHODS
  This is a retrospective investigation along with secondary topics from the raw data base. The subjective method used was result of the score of the application of a questionary about the sodium intake, where the sodium consumption report was converted into daily mg of sodium intake. The objective method was the result of the urine excretion of hypertensive persons older than 50 years during 24 hours. The topics were analyzed by the software SPSS using the Spearman correlation.
  
  
  RESULTS
  The main results did not show a significant linear correlation between the values of the sodium intake reported in the questionnaire and the values of the sodium (Na) 24 h collections.
  
  
  CONCLUSIONS
  New studies possibly will elucidate the present results among the divergence faced with other studies.
