Diet Intervention for Hypertension: Adaptation and Dissemination to Native Communities
Completed · Not applicable
Conditions studied: Hypertension
In brief
We will conduct a randomized trial to test our DASH (Dietary Approaches to Stop Hypertension) based intervention in 370 adult American Indians with inadequately controlled systolic blood pressure (≥130 mmHg). Over the 5 years of the project, we will recruit and randomize 200 participants from each of 4 urban sites: two in Washington, one in Oklahoma, and one in South Dakota.
