Young Adult Hypertension Self-Management Clinical Trial (MyHEART)

The MyHEART Study: A Young Adult Hypertension Self-Management Randomized Controlled Trial

This is a 5-year randomized controlled trial in two large healthcare systems (Madison and Milwaukee, WI) to evaluate MyHEART's (My Hypertension Education And Reaching Target) impact on blood pressure among 310 geographically and racially/ethnically diverse young adults.

Study Overview

• Status: Completed
• Conditions: Hypertension; Blood Pressure; Lifestyle Risk Reduction
• Intervention / Treatment: Behavioral: Home Blood Pressure Monitoring; Behavioral: Telephone Health Coaching

Detailed Description

Aim 1. To evaluate the effect of MyHEART (home blood pressure monitor distribution and heath coaching) on clinical outcomes, the change in systolic and diastolic blood pressure (primary) and hypertension control (secondary) after 6 and 12 months, compared to usual clinical care.

Aim 2. To evaluate the effect of MyHEART on hypertension self-management behavior (behavioral outcomes) at 6 and 12 months, compared to usual clinical care.

Aim 3. To examine whether MyHEART's effects on self-management behavior are mediated through variables of perceived competence, autonomy, motivation, and activation (mediation outcomes).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Intervention; Telephone health coaching, home blood pressure monitoring, individualized goal setting, and tailored educational materials	Behavioral: Home Blood Pressure Monitoring; Intervention arm participants will receive a home blood pressure monitor, home blood pressure log, and training on accurate home monitoring. They will be asked to share their home blood pressure readings during health coach telephone calls.; Behavioral: Telephone Health Coaching; Intervention arm participants will receive a health coach phone call every 2 weeks for 6 months, for a total of 12 calls. During each call, the health coach will review and discuss home blood pressures and address barriers and concerns to hypertension management. During each telephone call, the coach will guide the participant on selecting health behavior goals. Intervention arm participants will also receive handouts about hypertension management during the study visits and after health coach calls.
No Intervention: Usual clinical care; Usual care arm participants will receive routine hypertension clinical care per their primary care provider.
