Adherence
A dietitian-led telehealth intervention significantly reduces sleep (nocturnal) systolic and diastolic blood pressure more effectively than a self-directed digital approach.
If you want to improve your nighttime blood pressure, adding professional coaching to a digital health program is more effective than using the app alone. The dietitian support helps drive the lifestyle changes that specifically lower blood pressure during sleep.

However, sleep systolic BP decreased more in the telehealth dietitian arm (-6.92 mmHg, 95% CI: -9.33, -4.51) than the self-directed arm (-1.45 mmHg, 95% CI: -4.28, 1.38) with a difference of -5.47 mmHg (95% CI: -9.16, -1.79; p=0.004) between groups.
