Abstract BACKGROUND: Menopause is associated with poor sleep quality and daytime sleepiness, which may lead to impaired quality of life and impaired functioning in daily activities. OBJECTIVE: To study whether exercise training improves sleep quality or decreases the amount of night time hot flushes among menopausal women with vasomotor symptoms. STUDY DESIGN: A randomized controlled trial. Sedentary women (N=176) aged 43-63 years with menopausal symptoms were randomized to a six-month unsupervised aerobic training intervention (50 min 4 times per week) or a control group. Both groups attended lectures on physical activity and health once a month. MAIN OUTCOME MEASURES: Sleep quality and the amount of hot flushes disturbing sleep. The women reported daily via mobile phone whether hot flushes had disturbed their sleep and how they had slept (scale 1-5). Responses received by mobile phone over the 6-month period totaled on average 125 (5.2 per week) responses per participant. RESULTS: At baseline there was no difference between the groups in the demographic variables. Sleep quality improved significantly more in the intervention group than in the control group (OR 1.02; 95\% CI=1.0-1.05, p=0.043). The odds for sleep improvement were 2\% per week in the intervention group and a decrease of 0.5\% per week in the control group. The amount of hot flushes related to sleep diminished (p=0.004) by the end of the intervention. CONCLUSIONS: Aerobic training for 6 months may improve sleep quality and reduce hot flushes among symptomatic menopausal women. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.
