Community Study to Reduce High Blood Pressure Through Text Messaging (REACH OUT)

Not Applicable

Completed

• Conditions: Stroke; Hypertension

• Registration Number: NCT02664610
• Lead Sponsor: University of Michigan

Brief Summary

One of the most powerful predictors of stroke is hypertension, with estimates of approximately 33% of adults in the United States experiencing this condition. Hypertension is significantly more prevalent in African Americans compared to European Americans. Importantly, hypertension is a modifiable stroke risk factor.

This proposal will use a community-based participatory research approach to perform a randomized trial of a mobile phone text-messaging intervention to reduce high blood pressure in an urban African American community in Flint, Michigan.

Detailed Description

This is a randomized controlled trial of text messaging and blood pressure self-monitoring to reduce blood pressure.
