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.
Digital health approaches are promising intervention channels for improving DASH diet adherence. Almost all Americans own a mobile phone and 97% of mobile phone owners use text messaging. Digital health approaches can capitalize on the ubiquity of mobile technologies and allow investigators to reach affected populations with highly personalized content at low cost. Despite this ubiquity, interventions using text messaging for hypertension self-management primarily rely on reminders for tracking and medication adherence without diet and physical activity behaviors or feedback. As such, they are less effective. Investigators will establish the feasibility of a novel digital health-based approach for disseminating the DASH diet using the Amazon Alexa personal assistant. The data from this pilot feasibility trial will set the foundation for a larger, fully-powered R01 grant to examine whether DASH Cloud using Alexa can improve health outcomes. The primary aim of this proposal is to test the feasibility of the DASH Cloud intervention using Amazon Alexa.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

DASH Cloud with Alexa
Behavioral: DASH cloud with 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.

Ran from Jul 2018 to primary completion in Dec 2018, 4 months.
Of 568 non-industry interventional studies with no phase under Health Behavior, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 33. This study's 4 months is below that.
Counting every sponsor, half of 586 studies reached it within 15 months; a quarter within 5 and three quarters within 32.
