ABSTRACT:

Background

Dietary Approaches to Stop Hypertension (DASH) is a recommended first-line treatment for adults with hypertension, yet adherence to DASH is low. To evaluate the efficacy of a digital health intervention (DHI), compared with attention control, on changes in DASH adherence and blood pressure among adults with hypertension.

Nourish was a 12-month, parallel, 2-arm, randomized controlled trial of a virtually delivered DHI. Participants had a previous diagnosis of hypertension. The primary outcome was a 6-month change in DASH adherence. The secondary outcome was a change in blood pressure. We used linear mixed models to compare 6 and 12-month changes in DASH adherence, systolic blood pressure, and diastolic blood pressure.

Results
