Brief Summary

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.

Interventions

DASH cloud with Alexa BEHAVIORAL

Participants will download and install the Alexa and Nutritionix application ("app") onto their smartphone and study staff will setup the study-specific account to send data to Duke's software system called Prompt. Participants will be instructed to invoke through voice their dietary intake daily for three months using the Nutritionix app through the Amazon Alexa personal assistant. DASH Cloud will access participant's dietary intake data through the Nutritionix application programing interface (API) for three months. Participants' data will automatically be uploaded from the Nutritionix app via the API that links the device with DASH Cloud. DASH Cloud will run an algorithm and send a daily or weekly feedback text message with a score reflecting DASH adherence for the prior days or week's food consumption using a previously validated scoring system.
