Abstract
Background and objective. To estimate whether aerobic training has an effect on frequency of hot flushes or quality of life.Design. A randomized controlled trial.Participants and setting. Symptomatic, sedentary women (n = 176), 43–63 years, no current use of hormone therapy.Intervention. Unsupervised aerobic training for 50 minutes four times per week during 6 months.Outcomes. Hot flushes as measured with Women's Health Questionnaire (WHQ) and Health-Related Quality of Life (HRQoL, SF-36), daily reported hot flushes on phone-based diary, cardiorespiratory fitness (CRF), and body composition.Results. Intervention group had larger decrease in the frequency of night-time hot flushes based on phone diary (P for month × group = 0.012), but not on WHQ scale. Intervention group had less depressed mood (P = 0.01) than control women according to change in WHQ score. Changes in WHQ score in depressed mood (P = 0.03) and menstrual symptoms (P = 0.01) in the intervention group were significantly dependent on frequency of training sessions. HRQoL was improved among the intervention group women in physical functioning (P = 0.049) and physical role limitation (P = 0.017). CRF improved (P = 0.008), and lean muscle mass increased (P = 0.046) significantly in the intervention group as compared to controls.Conclusions. Aerobic training may decrease the frequency of hot flushes and improve quality of life among slightly overweight women.
Highlights
Hot flushes are a common complaint in many women and may occur for years beyond menopausal transition [1,2,3]
Traditional post-menopausal hormone therapy (HT) is the most effective treatment to alleviate menopausal hot flushes, it has been subject to major criticism due to the results of large clinical trials in which the risks of HT have outweighed the benefits [5].Women with higher adiposity report more severe hot flushes [6], and successful weight loss has been associated with hot flush decrease in a randomized trial [7]
Our objective was to estimate whether aerobic training decreases hot flushes or increases health-related or menopause-specific quality of life among symptomatic menopausal women
Summary
Hot flushes (i.e. vasomotor symptoms) are a common complaint in many women and may occur for years beyond menopausal transition [1,2,3]. To estimate whether aerobic training has an effect on frequency of hot flushes or quality of life. Intervention group had larger decrease in the frequency of night-time hot flushes based on phone diary (P for month ϫ group ϭ 0.012), but not on WHQ scale. Intervention group had less depressed mood (P ϭ 0.01) than control women according to change in WHQ score. Changes in WHQ score in depressed mood (P ϭ 0.03) and menstrual symptoms (P ϭ 0.01) in the intervention group were significantly dependent on frequency of training sessions. CRF improved (P ϭ 0.008), and lean muscle mass increased (P ϭ 0.046) significantly in the intervention group as compared to controls. Aerobic training may decrease the frequency of hot flushes and improve quality of life among slightly overweight women
