Brief Summary

People with high blood pressure and diabetes often have low levels of key nutrients as a result of not eating enough fresh fruits and vegetables. Research studies suggest that these nutrients can lower blood pressure and blood sugar. This study will investigate if providing encouragement to adopt this healthy and nutritious way of eating and providing guidance on weight management will lower blood pressure and blood sugar. The DASH-Life research study will recruit adults with hypertension and type 2 diabetes who live in Baltimore metro areas that don't have many stores selling healthy foods. The DASH-Life research study is 6 months long. Participants will be randomly assigned to one of two groups: 1) Self-Shopping DASH (S-DASH) diet advice group, or 2) Coaching DASH (C-DASH) diet advice group.

Outcome Measures

Primary Outcomes (2)

  • Feasibility as assessed by the number of participants enrolled

    The observed count of responses to the prescreening will be summarized. Recruitment yields at screening visit and randomization visit will be derived.

    Baseline

  • Acceptability as assessed by the Acceptability of the Intervention Measure survey

    Acceptability of the intervention will be quantitatively measured by the Acceptability of Intervention Measure (AIM) survey. The survey consists of 4 items, each measured on a 5-point Likert scale from 1 (completely disagree) to 5 (completely agree). The score is calculated as the mean of the responses to the 4 items. A higher score is better.

Study Arms (2)

Self-Shopping DASH diet advice group (S-DASH)

ACTIVE COMPARATOR
Behavioral: Self-Shopping DASH diet advice

Coach-Directed Tailored DASH Groceries Plus Lifestyle Intervention (C-DASH)

EXPERIMENTAL
Behavioral: Coach-Directed Tailored DASH Groceries Plus Lifestyle Intervention

Interventions

Participants assigned to the C-DASH group will meet by telephone with the study coach for 1 hour, and then have brief weekly conversations (about 15-30 minutes) by phone during the first three months. During these weekly calls, the study coach will assist participant with selecting fruits, vegetables, nuts, and beans. During months 4-6, the study coach will continue to work with participant to set goals for following the DASH-Life way of eating, but the study will no longer provide a weekly food allowance to purchase groceries.

Coach-Directed Tailored DASH Groceries Plus Lifestyle Intervention (C-DASH)

Participants assigned to the S-DASH group will receive a brochure about the DASH eating plan. For the first three months, Participants will also receive a gift card to shop at a local supermarket. During months 4-6, participants will be asked to continue following the DASH eating plan listed in the brochure but will no longer be provided the grocery gift card.
