What this trial studies

This study aims to enroll 65 adults with hypertension who have limited access to high-quality food. Participants will receive a digital health intervention that includes grocery delivery services and a comprehensive behavioral program designed to enhance adherence to the DASH eating pattern. The intervention features skills training, dietary tracking, personalized feedback, and health coaching over a 4-month period. The primary focus is on evaluating the feasibility of the intervention, along with changes in dietary adherence and blood pressure levels.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with hypertension and limited access to nutritious food.

Not a fit: Patients with severe obesity, recent cardiovascular events, or other significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve dietary quality and blood pressure management for patients with hypertension.

How similar studies have performed: Other studies have shown promise in using digital health interventions to improve dietary habits, suggesting potential success for this approach.
