A randomized, placebo-controlled trial of the effects of physical exercises and estrogen therapy on health-related quality of life in postmenopausal women.
Many women experience detriments in mental health during the menopausal transition. Physical activity may attenuate these adverse outcomes but few studies investigating such effects exist.
                This study examined the effects of a 4-month randomized controlled exercise trial on mental health outcomes in 164 previously low-active middle-aged women (M age = 49.9; SD = 3.6).
                Participants completed body composition and fitness assessment and a battery of psychological measures at the beginning and end of a 4-month randomized controlled exercise trial with three arms: walking, yoga, control. The results indicated that walking and yoga were effective in enhancing positive affect and menopause-related QOL and reducing negative affect. Women who experienced decreases in menopausal symptoms across the trial also experienced improvements in all positive mental health and QOL outcomes and reductions in negative mental health outcomes. Whether menopausal symptoms increased or decreased across the trial appeared to be determined in part by whether there were increases or decreases in cardiorespiratory fitness.
                Physical activity appears to enhance mood and menopause-related QOL during menopause, however, other aspects of mental health may be affected only as a result of reduction in menopausal symptoms. Increasing cardiorespiratory fitness could be one way to reduce menopausal symptoms. To assess if regular physical exercise or oral oestradiol therapy decreased vasomotor symptoms and increased quality of life in previously sedentary postmenopausal women.
                A prospective, randomised trial at a University Hospital.
                75 postmenopausal, sedentary women with vasomotor symptoms were randomised to: exercise three-times weekly over 12 weeks (15 women), oral oestradiol therapy for 12 weeks (15 women) and 45 women to three other treatment arms. Results from the exercise and oestradiol groups are presented here. The effects on vasomotor symptoms and wellbeing were assessed with logbooks and validated questionnaires.
                Ten women fulfilled 12 weeks of exercise. The number of flushes was rather unchanged in five women and decreased to 28% (range 18-42%) of baseline in the other five women. Five of the ten women continued to exercise another 24 weeks, thus in all 36 weeks. The mean number of flushes decreased by about 50% in these five women (from 6.2/24 to 3.2 flushes/24 h at 36 weeks). In the same group a score made as the product of reduction in number and severity of flushes decreased by 92% at 12 weeks, 75% at 24 weeks and 72% at 36 weeks compared with baseline. In the estrogen group flushes decreased from 8.4 to 0.8 (P<0.001) after 12 weeks of therapy and remained at this level after 36 weeks. Well-being according to different measurements improved significantly in both groups, albeit more markedly in the estrogen group.
                Apart from many other health benefits regular physical exercise may decrease vasomotor symptoms and increase quality of life in postmenopausal women, but this has to be further evaluated scientifically. Exercise should be introduced gradually to ensure compliance. Physical activity has been shown to enhance quality of life (QOL); however, few investigations of these effects exist in women undergoing the menopausal transition. The present study examined the long-term effects of physical activity on menopause-related QOL and tested the mediating effects of physical self-worth and positive affect in this relationship.
                Middle-aged women previously enrolled in a 4-month randomized controlled trial involving walking and yoga, and a control group completed a follow-up mail-in survey 2 years after the end of the trial. The survey included a battery of psychological and physical activity measures, including measures of menopausal symptoms and menopause-related QOL. Longitudinal linear panel analysis was conducted within a covariance modeling framework to test whether physical self-worth and positive affect mediated the physical activity-QOL relationship over time.
                At the end of the trial, physical activity and menopausal symptoms were related to physical self-worth and positive affect, and in turn, greater levels of physical self-worth and positive affect were associated with higher levels of menopause-related QOL. Analyses indicated that increases in physical activity and decreases in menopausal symptoms over the 2-year period were related to increases in physical self-worth (betas = 0.23 and -0.52, physical activity and menopausal symptoms, respectively) and, for symptoms, also to decreased positive affect (beta = -0.47), and both physical self-worth (beta = 0.34) and affect (beta = 0.43) directly influenced enhancements in QOL (R = 0.775).
                The findings support the position that the effects of physical activity on QOL are mediated, in part, by intermediate psychological outcomes and that physical activity can have long-term benefits for women undergoing the menopausal transition. The effects of physical training and hormone replacement therapy (HRT) on bone mineral density in perimenopausal women were studied. Sixty perimenopausal women were randomized to either physical training (n = 20), HRT (n = 20), or control group (n = 20). The study period was 18 months. Bone mineral density (BMD) in the femoral neck and lumbar spine was measured using dual-energy X-ray absorptiometry (DXA). DXA was performed before treatment and after 6 and 18 months. Blood samples for analysis of the bone markers U-deoxypyridinoline and osteocalcin were collected at the same time points. After 18 months, BMD in the spine had not decreased in either the training group or in the HRT group. In the control group, spine BMD had significantly decreased (p = 0.0014). U-Deoxypyridinoline and osteocalcin were increased significantly in the control group (p = 0.0198, p = 0.0295, respectively). No significant changes in bone marker levels were found in the training group or the HRT group. We found that both HRT and physical training can prevent loss of spine BMD in perimenopausal women over a period of 18 months. HRT remains a cornerstone in the treatment of vasomotor symptoms and preservation of BMD. However, HRT can only be used for limited periods of time due to the potential serious adverse effects. This study indicates a beneficial effect of physical activity on spine BMD in the perimenopausal period, and highlights its potential as an alternative to HRT during this period. With advancing age, the postural balance function deteriorates as a consequence of decreased functional capacity. Deteriorating balance is a risk factor for bone fractures due to increased risks of falls. It has been suggested that the loss of estrogen, which occurs in relation to the menopause, may be associated with loss of balance. Regular physical exercise without balance training has, in some studies, been shown to have positive effects on the postural balance. The aim of the present study was to examine balance function during the perimenopausal period, and evaluate the effect of estrogen plus progesterone therapy (EPT) or aerobic training on balance. Sixty perimenopausal women were recruited to the study. The subjects were then randomised to either physical training (n=20), EPT (n=20), or to a control group (n=20). The study period was 18 months. Postural stability was measured every third month using a custom-made force platform. The women using EPT achieved better results in 3 of 6 parameters, after 18 months. The purpose of this study was to evaluate the isolated and associated effects of estrogen therapy (estradiol valerate 1 mg/d orally) and physical exercise (moderate aerobic exercise, 3 h/wk) on health-related quality of life (HRQOL) and menopausal symptoms among women who had undergone hysterectomy.
                A 6-month, randomized, double-blind, placebo-controlled clinical trial with 44 postmenopausal women who had undergone hysterectomy. The interventions were physical exercise and hormone therapy (n = 9), being sedentary and hormone therapy (n = 14), physical exercise and placebo (n = 11), and being sedentary and placebo (n = 10). HRQOL was assessed by a Brazilian standard version of the Medical Outcome Study Short-Form Health Survey and symptoms by Kupperman Index at baseline and after 6 months.
                There was a decrease in symptoms in all groups, but only groups who performed physical exercise showed an increase in quality of life. Analysis of variance showed that changes in physical functioning (P = 0.001) and bodily pain (P = 0.012) scores over the 6-month period differed significantly between women who exercised and women who were sedentary, regardless of hormone therapy. Hormone therapy had no effect, and there was also no significant association between physical exercise and hormone therapy in HRQOL.
                Physical exercises can reduce menopausal symptoms and enhance HRQOL, independent of whether hormone therapy is taken.
The existing studies provided insufficient evidence to determine the effectiveness of exercise as a treatment for vasomotor menopausal symptoms, or whether exercise is more effective than HRT or yoga.
