Testing the Feasibility of the DASH Cloud Intervention Using Amazon Alexa

"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."
