In 30 seconds
This randomized clinical trial evaluated the effectiveness of the NamakBan smartphone application for monitoring sodium intake in 88 adults with primary hypertension. The intervention group showed significant reductions in both systolic and diastolic blood pressure compared to the control group. Over two months, self-reported sodium intake also decreased more in the intervention group, although urinary sodium-to-potassium ratios did not differ significantly between groups.
Key findings
- Systolic blood pressure decreased significantly in the intervention group compared to control.
- Diastolic blood pressure also showed significant reductions in the experimental group.
- Self-reported daily sodium intake declined more in the intervention group than in the control.
- No hypertension-related hospital readmissions occurred in the intervention group.
Why it matters
Effective management of dietary sodium intake is crucial for controlling blood pressure in hypertensive patients. This study suggests that mobile health applications can enhance patient engagement and potentially improve clinical outcomes.
What to keep in mind
The trial was single-centre, had a short follow-up of two months, and relied on unblinded self-reported dietary sodium intake.
