• 2 other identifiers: IRB00447049R21NR021041
• Study Type: interventional
• Target: 67
• Locations: 1 country
• Sites: 1

Brief Summary

A total of 65 participants with hypertension and low access to high quality food will be enrolled to test the feasibility of using commercially available grocery delivery services, simultaneous to a robust behavioral intervention, to improve adherence to the Dietary Approaches to Stop Hypertension (DASH) eating pattern. The behavioral intervention will include skills training, nutrient goal setting, self-monitoring via dietary tracking, personalized text message feedback, and adaptive health coaching. Participants will also receive a membership to Instacart+ and weekly grocery list recommendations from a health coach. The primary outcome will be indicators of feasibility, including acceptability, demand, implementation and practicality and adaption. Change in DASH adherence and blood pressure will also be evaluated. The intervention period for participants will be 4 months.

Outcome Measures

Primary Outcomes (1)

• Feasibility as assessed by survey

  Feasibility will be measured by a 23-item questionnaire used to assess participants' perceptions of the feasibility, usability, acceptability, practicality, and satisfaction with the intervention. Each item is rated on a 5-point Likert scale, with higher scores indicating greater feasibility and acceptability. The survey evaluates key components of the program, including grocery lists, grocery delivery, health coaching, and app-based tracking.

  4 months

Secondary Outcomes (3)

• Change in DASH Score as assessed by the Automated Self-Administered 24-hour (ASA24)

  Baseline and 4 months

• Change in Systolic Blood Pressure
