Trial summary

This study will test whether a digital health intervention (DASH Cloud) using smartphones can improve diet quality among women at risk for cardiovascular disease. The DASH (Dietary Approaches to Stop Hypertension) Diet has been proven to lower blood pressure, yet dissemination efforts remain poor. Read more about this study

About this study

Official title: DASH Cloud: Using Digital Health to Improve Adherence to the DASH Diet Among Women at Risk for Cardiovascular Disease

This study will test whether a digital health intervention (DASH Cloud) using smartphones can improve diet quality among women at risk for cardiovascular disease. The DASH (Dietary Approaches to Stop Hypertension) Diet has been proven to lower blood pressure, yet dissemination efforts remain poor. This study aims to use technology to improve adherence to DASH.

Read the detailed description

Specifically, this study aims to

  1. To test the feasibility of the DASH Cloud intervention compared to education control among women with prehypertension and hypertension via a 3-month randomized controlled trial.
  2. To evaluate the preliminary efficacy of the DASH Cloud intervention relative to education control on blood pressure, weight and medication adherence at 3 months.

This study will enroll 50 adult women aged 21-70 with pre-hypertension or hypertension in a 3-month randomized controlled trial to test the initial feasibility of DASH Cloud. Women will be randomized to either the DASH Cloud intervention or DASH Light and followed up 3 months post randomization. The investigators will recruit participants from the Durham, NC area.

Women randomized to the DASH Cloud intervention will be asked to track their diet daily using a smartphone diet tracking app. Based on the foods/beverages entered, the intervention will send daily or weekly text messages with feedback about DASH adherence and information videos about how to follow DASH. Women randomized to DASH Light will also be asked to track their diet using the smartphone diet tracking app and will receive basic informational materials about DASH.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DASH CloudOther

    With DASH Cloud, the investigators will ask participants to track their diet daily using a commercial diet tracking app. The investigators will retrieve the diet data on our DASH Cloud platform and provide tailored feedback about a participant's DASH adherence via fully automated daily or weekly text messages. These feedback messages will describe both an individual's absolute performance and change over time. The investigators also include theory-driven tailored content that reinforces successes, offers motivational strategies, and offers short behavior change tips.

  • Nutritionix Track appOther

    Also called DASH Light

    DASH Light Control participants will be asked to use the Nutritionix app daily and receive publicly available written materials on the DASH diet.

Study groups in NCT03215472
Study groupRoleWhat they receive
DASH Cloud interventionExperimentalIn group 1, participants will be instructed to input their dietary intake daily for three months using the Nutritionix app. A participant's 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 daily or weekly feedback text messages reflecting DASH adherence. The intervention components include tailored feedback texts, and behavioral skills training videos.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Adherence to the DASH Diet

    Dietary intake data will be collected using NCI's Automated Self-Administered 24-hour Recall tool.

    Measured: 3 months

Secondary outcomes (4)
  1. Change in Blood Pressure

    Blood pressure will be measured at baseline and 3 months in the upper arm in triplicate at 1-minute intervals. Measurements will be obtained using the validated Omron HEM-907XL blood pressure monitor.

    Measured: Baseline, 3 months

  2. Change in Weight

    Weight will be collected in kilograms at baseline and 3 months using a calibrated digital scale.

    Measured: Baseline, 3 months

  3. Engagement

    Utilization of intervention component (daily diet tracking using Nutritionix app) at 3 months. This will be measured by the proportion of participants completing daily dietary self-monitoring.

    Measured: 3 months

  4. Engagement

    Utilization of intervention component (review of skills training videos) at 3 months. This will be measured by the number of clicks to skills training via video tracking software.

    Measured: 3 months

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03215472, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
