Adherence
A 12-week dietitian-led telehealth intervention using web-based applications reduces 24-hour systolic blood pressure by approximately 6.7 mmHg, achieving efficacy comparable to a self-directed approach using the same digital tools.
To lower your blood pressure, you can use a structured digital program. If you add weekly check-ins with a dietitian who helps you set goals and stay motivated, you may get an extra benefit in nighttime blood pressure and physical activity, but the core digital tools alone will still significantly lower your daytime blood pressure.
Mean 24-hour systolic BP improved from baseline to 12 weeks similarly in the dietitian (-6.73 mmHg, 95% CI: -8.64, -4.82) and the self-directed arm (-4.92, 95% CI: -7.01, -2.77; p comparing groups=0.2).
Why this rating
Randomized controlled trial with high completion rate (83.4%), though the preprint is not yet peer-reviewed.
