Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The DASH diet is a proven behavioral strategy to reduce blood pressure, however, national adherence rates are poor. Using digital health tools may help to improve adoption of the DASH diet. Digital health approaches capitalize on the ubiquitous utilization of mobile technologies and have broad dissemination potential. There have been few efforts to test a DASH intervention via digital, and none using voice-activated technologies (e.g, Amazon Alexa). This proposal will enroll up to 20 participants to leverage a commercial diet tracking application, an existing intervention technology platform and the Amazon Echo Dot to test the feasibility of using DASH Cloud, a digital health intervention, with the Amazon Alexa personal assistant.
