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

Active, not recruiting

Phase 1 Results N/A

Trial Description

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.



  • Text messaging Behavioral
    Intervention Desc: hypertensive participants will be randomized to receive tailored, motivational text messages
    ARM 1: Kind: Experimental
    Label: Text messages, hypertensive
    Description: Participants who have high blood pressure, who are randomized to receive text messages.

Trial Design

  • Allocation: Randomized
  • Masking: Open Label
  • Purpose: Treatment
  • Intervention: Parallel Assignment


Type Measure Time Frame Safety Issue
Primary Change in systolic and diastolic blood pressure 6 months No
Secondary Proportion of persistently hypertensive participants who respond to text messages 6 months No
Secondary Feasibility of subject follow-up mechanism (Proportion of subjects responding to follow-up text messages) 6 months No
Secondary Mean group differences for systolic blood pressure 6 months No
Secondary Mean group differences for medication adherence 6 months No
