Study Population

The study was conducted with 407 adult volunteer participants living in the Washington DC, Maryland areas who met the following criteria:

You may qualify if:

  • English speaking
  • Aged 18-39 years old
  • % Black; 50% all other
  • % male; 50% female
  • At least 50 (25 male; 25 female) of the 400 participants likely to have high sodium diet indicated by selected dietary behaviors
  • At least 50 (25 male; 25 female) of the 400 participants likely to have low sodium diet indicated by selected dietary behaviors

You may not qualify if:

  • Pregnant or trying to get pregnant.
  • Taking loop diuretics
  • Chronic kidney disease
  • New hypertension treatment or change in hypertension treatment in the last 2 weeks
