The purpose of this study is to determine the effects of yoga on blood pressure and quality of life in patients in primary health care diagnosed with hypertension within the last year. Another purpose is to examine whether the possible effect on blood pressure differs if patients practice yoga in a group lead by a yoga-trainer or receive a few yoga-exercises from their doctor to be practiced individually at home.

Condition Intervention
Other: Yoga group with supervision (trainer)
Other: Yoga at home

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: The Impact of Yoga on Blood Pressure and Quality of Life in Patients With Hypertension - a Randomised Controlled Trial in Primary Health Care

Further study details as provided by Region Skane:

Primary Outcome Measures:
  • Hypertension [ Time Frame: 12 weeks ]
    At the beginning of the study, all subjects will undergo a standardized blood pressure test with an hypertension monitor. After 12 weeks, all subjects in the intervention and control groups will again be requested to attend a blood pressure testing session. Blood samples will also be collected and analysed in the beginning and at the end of the study. Some blood samples will be preserved for future analysis.

Secondary Outcome Measures:
  • Quality of life [ Time Frame: 12 weeks ]
    At the beginning of the study, all subjects will be requested to fill in a questionnaire about their quality of life (WHOQOL-BREF). After 12 weeks all subjects in the intervention and control groups will fill in the quality of life-form for a second time.

Enrollment: 83
Study Start Date: March 2011
Study Completion Date: June 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Yoga group with supervision/trainer Other: Yoga group with supervision (trainer)
The Yoga-with-trainer group will meet once a week (60 minutes) to practice yoga with a yoga instructor. The participants will be encouraged to practice yoga between the yoga classes at home for 30 minutes a day.
Active Comparator: Yoga at home Other: Yoga at home
The participants in the Yoga-at-home group will get a private doctor appointment (20 minutes) where they get instructions for two yoga exercises which they are encouraged to perform at home 15 minutes a day.
No Intervention: Control
No changes will be made for the participants in the control group, but they will undergo the same measurements and evaluations as the intervention groups.

Detailed Description:

Hypertension is one of the most common diseases in the industrialized world. In Sweden alone approximately 1.8 million persons, 25% of the adult population, have hypertension. Hypertension is a common diagnosis in primary health care and the costs of investigating and treating hypertension and its consequences are considerable. We know that stress can affect blood pressure, but it is hard to measure and control.

Previous studies have separately shown that yoga can reduce levels of cortisol in saliva and lower blood pressure. However, few studies have investigated the effects of yoga on hypertension and we lack information about the possibility of using yoga in primary health care to reduce hypertension.

If yoga can be used to complement antihypertensive medicines, it could reduce medicine intake and thereby possibly reduce side effects and lower medicine costs. It is to be hoped that patients will also experience a higher quality of life if they perform yoga on a regular basis.
