Boodschappen plus multi-component levensstijlinterventie voor volwassenen met hypertensie en type 2 diabetes (DASH-Life)
Boodschappen plus multi-component levensstijlinterventie voor volwassenen met hypertensie en type 2 diabetes die in stedelijke voedselwoestijnen wonen (dash-life): piloot gerandomiseerde klinische studie
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.

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. |
