In plain words

What the trial is, and whether it could suit you

The goal of this study is to explore the barriers and facilitators to adopting a reduced dietary salt and increased potassium intake among adults with essential hypertension in Singapore, and to evaluate the feasibility and preliminary effectiveness of a newly developed educational tool-Decreased Salt High Potassium (DSHP) Diet Tool-in reducing dietary sodium intake and increasing potassium intake. This three-part study will involve adults aged 21 years and above, with a self-reported diagnosis of hypertension for at least six months and/or currently taking antihypertensive medication. Participants will be recruited from two SingHealth Polyclinics (Punggol Polyclinic and Pasir Ris Polyclinic). Healthcare providers (HCPs) working at these clinics who have experience in managing patients with hypertension and in educating patients on reducing dietary sodium intake will also be recruited.
