History of Changes
  Purpose
The purpose of this study is to determine if Mindfulness Based Stress Reduction (MBSR) is an effective intervention for lowering blood pressure in early unmedicated hypertensives.

Condition Intervention
Hypertension Behavioral: Mindfulness Based Stress Reduction (MBSR) Therapy

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single (Investigator)
Primary Purpose: Treatment
Official Title: HARMONY Study (Hypertension Analysis of Stress Reduction Using Mindfulness Meditation and Yoga)

Further study details as provided by Sheldon Tobe, Sunnybrook Health Sciences Centre:

Primary Outcome Measures:
  • The primary outcome is the difference in 24-hour systolic and diastolic blood pressure between the treatment and wait-list group for the 12-week primary assessment period. [ Time Frame: 12 weeks ]

Secondary Outcome Measures:
  • Changes in 24 hour ambulatory systolic and diastolic blood pressure at the end of the treatment assessment period compared to the beginning. [ Time Frame: 12 weeks ]
  • Between and within group comparisons of MBSR on blood pressure at different times of the day including daytime, night time and work time. [ Time Frame: 24 weeks ]
  • The proportion of patients achieving blood pressure targets (24-hour ABPM<130/80 mmHg, daytime ABPM<135/85 mmHg) at the end of the Primary Outcome period [ Time Frame: 24 weeks ]
  • The effect of MBSR on ambulatory blood pressure by gender [ Time Frame: 24 weeks ]
Enrollment: 101
Study Start Date: July 2008
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Early Intervention, MBSR therapy
Group that receives Mindfulness Based Stress Reduction Therapy immediately after randomization
 Behavioral: Mindfulness Based Stress Reduction (MBSR) Therapy
The objectives of MBSR therapy are to 1) understand their personal response to stress and 2) develop techniques to change the way these patients respond and cope with stress
Other Names:
  • stress reduction therapy
  • Jon Kabat-Zinn
  • mindfulness meditation
Active Comparator: Delayed Treatment Arm, MBSR Therapy
Group that receives Mindfulness Based Stress Reduction Therapy within 3 months of randomization
 Behavioral: Mindfulness Based Stress Reduction (MBSR) Therapy
The objectives of MBSR therapy are to 1) understand their personal response to stress and 2) develop techniques to change the way these patients respond and cope with stress
Other Names:
  • stress reduction therapy
  • Jon Kabat-Zinn
  • mindfulness meditation
