Reduced-salt, higher-potassium diet to help control blood pressure in adults with hypertension

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This three-part study first explores patient and healthcare provider perspectives on barriers and facilitators to adopting a reduced-salt, high-potassium diet. It then pilots the Decreased Salt High Potassium (DSHP) Diet Tool to test feasibility and preliminary effects on dietary sodium and potassium intake in adults with essential hypertension recruited from two SingHealth polyclinics. Eligible participants are adults aged 21 and above with a self-reported diagnosis of hypertension for at least six months or who are taking antihypertensive medication, and healthcare providers involved in dietary counselling are also included. Primary outcomes focus on changes in reported or measured sodium and potassium intake and feasibility measures such as acceptability, recruitment, and retention.
