Key result
An educational intervention by a dietitian was not significantly different from usual care in reducing 24-h sodium urinary excretion (-1670 vs -1610 mg/day) in patients with hypertension.
Why the study?
Non-pharmacological interventions effectively lower blood pressure, but adherence is typically poor, prompting the need for behavioral change interventions to reinforce sodium restriction adherence.
Does a DSRQ-based educational intervention reduce 24-h sodium urinary excretion in patients with hypertension compared to usual care?
Population

DSRQ-based education yields no sodium or BP benefit over usual advice in hypertension; leaves open optimal strategies for dietary adherence.

Does a DSRQ-based educational intervention reduce 24-h sodium urinary excretion in patients with hypertension compared to usual care?
Absolute Event Rate: -1670% vs -1610%
An intensive educational intervention by a dietitian was no more effective than usual dietary recommendations for reducing sodium intake in hypertensive patients.
Rodrigues et al. (2023) conducted an RCT in Hypertension (n=120). Educational intervention by a registered dietitian vs. Usual care and dietary recommendations was evaluated on Change in 24-h sodium urinary excretion. An educational intervention by a dietitian was not significantly different from usual care in reducing 24-h sodium urinary excretion (-1670 vs -1610 mg/day) in patients with hypertension.
