Key result
A low sodium intervention in hypertensive older adults reduced urinary sodium from 3,240 mg at baseline to 2,990 mg at 6 months, though self-reported intake significantly underestimated actual excretion.

Does a low sodium intervention reduce sodium intake in older adults with hypertension?
Self-reported dietary sodium significantly underestimates actual intake measured by 24-hour urinary sodium in older adults, highlighting the need for objective measurements and food industry changes to achieve sodium reduction goals.
Courtney B. Johnson (2006) conducted a cohort in Hypertension and high dietary sodium (n=521). Low sodium intervention was evaluated on Urinary sodium excretion. A low sodium intervention in hypertensive older adults reduced urinary sodium from 3,240 mg at baseline to 2,990 mg at 6 months, though self-reported intake significantly underestimated actual excretion.
