About this study
This study is the second clinical trial to be conducted by the Menopause Strategies - Finding Lasting Answers for Symptoms and Health (MsFLASH) research network, a group of investigators conducting clinical trials designed to find new ways to alleviate the most common, bothersome symptoms of the menopausal transition.
In this twelve-week clinical trial, 374 women aged 40-62 who are in the late menopausal transition or postmenopausal and experiencing bothersome hot flashes will be randomized to one of three behavioral intervention groups: yoga, exercise, or usual activity. All women will simultaneously be randomized to receive omega-3 supplementation or a matching placebo.

The primary aims of this trial are to compare the magnitude of changes in perceived, self-reported frequency and bother of vasomotor symptoms (VMS) before and after the intervention between yoga and the usual activity comparison group, between exercise and the usual activity comparison group, and between omega-3 fatty acid supplementation or placebo. The hypotheses to be tested are:
- Women assigned to yoga will report lower frequency and less VMS bother than women assigned to the usual activity group at the end of a 12-week study period.
- Women assigned to aerobic exercise at moderate-vigorous intensity will report lower frequency and less VMS bother than women assigned to the usual activity group at the end of a 12-week study period.
- Women assigned to omega-3 fatty acid supplementation will report lower frequency and less VMS bother than women assigned to the placebo group at the end of a 12-week study period.
The omega-3 component of the study is double-blinded. For yoga, exercise, and usual activity, the outcomes assessors are blinded to the randomization assignments.
Read the detailed description
Over 33 million U.S. women will transition through menopause in the next decade. Among women with natural menopause, the transition typically lasts four years, with a mean age at menopause of 51 years. Menstrual irregularity (90%) and vasomotor symptoms (VMS) (80%) are the most common symptoms associated with the transition. Hormone therapy has been the gold standard for treating VMS symptoms against which other therapies are measured. However, resistance to hormone therapy use due to its risks and side effects continues to fuel the search for safer alternatives.
This research study will evaluate three low risk interventions (yoga, exercise, and omega-3 supplements) compared to either a usual activity group or a placebo pill. This factorial design is motivated by the desire to have all women receive some intervention. Neither comparisons between yoga and exercise nor tests of interaction between the behavioral interventions (yoga, exercise, usual activity) and omega-3 motivated this design. However, these aspects can be examined in secondary analyses in a more rigorous fashion through this design than would be permitted by separate trials.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PlaceboDietary supplement
Three placebo gel capsules filled with vegetable oil are taken daily for a total of approximately 2 grams of vegetable oil. Each gel capsule also contains 15 IU of vitamin E, natural lemon flavoring, rosemary extract, and a small amount of non-omega-3 fish oil.
Omega-3Dietary supplement
The study supplement, omega-3-fish oils, is taken as 3 gel capsules daily that together contain approximately 2 grams of fish oil. Each gel capsule (1/3 of the daily dose) has a total omega-3 dosage of 615 mg with two major omega-3 components of ethyl eicosapentaenoic acid (EPA; 425 mg) and docosahexaenoic acid (DHA; 100 mg). Vitamin E (15 IU), an antioxidant, is added to each gel capsule to prevent oxidation and preserve freshness. Each gel capsule also contains natural lemon oil and rosemary extract to enhance taste and freshness.
YogaBehavioural
Yoga instruction is provided during 12 weekly 90-minute classes, designed for women without prior yoga experience. Each class includes an introductory breathing exercise, 11 to 13 gentle postures followed by deep relaxation with a visualization exercise. Study participants are expected to attend each of the 12 weekly yoga classes plus do daily 20-minute at-home practices. Classes are offered at 2 different times during the week.
ExerciseBehavioural
The exercise intervention is facility-based aerobic exercise training on a treadmill, stationary bicycle or elliptical trainer performed 3 times a week for 12 weeks. The duration of each training session is determined for each woman based on the weekly total energy expenditure goal and workload required to achieve her prescribed exercise heart rate. Women train at 50-60% heart rate reserve (HRR) for the first month and then increase intensity to 60-70% HRR. To ensure that women train at their prescribed exercise heart rates, women wear Polar Heart Rate Monitors while exercising. The exercise counselor overseeing each exercise session records each participant's exercise heart rate every 5-10 minutes to document that she is in her target heart rate range.
Usual ActivityBehavioural
Women randomly assigned to the "Usual Activity" group will be asked to continue with their usual physical activities during the study and not make changes. At completion of the intervention, women will have the opportunity to attend a yoga class and receive the yoga booklet, CD, and DVD for home use; or receive a one-month gym membership.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study is the second clinical trial to be conducted by the Menopause Strategies - Finding Lasting Answers for Symptoms and Health (MsFLASH) research network, a group of investigators conducting clinical trials designed to find new ways to alleviate the most common, bothersome symptoms of the menopausal transition.

All women will simultaneously be randomized to receive omega-3 supplementation or a matching placebo.
