Treating the climacteric symptoms in Indian women with an integrated approach to yoga therapy: a randomized control study

Effectiveness of yoga for menopausal symptoms: a systematic review and meta-analysis of randomized controlled trials

Objectives. To systematically review and meta-analyze the effectiveness of yoga for menopausal symptoms. Methods. Medline, Scopus, the Cochrane Library, and PsycINFO were screened through April 2012. Randomized controlled trials (RCTs) were included if they assessed the effect of yoga on major menopausal symptoms, namely, (1) psychological symptoms, (2) somatic symptoms, (3) vasomotor symptoms, and/or (4) urogenital symptoms. For each outcome, standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated. Two authors independently assessed risk of bias using the risk of bias tool recommended by the Cochrane Back Review Group. Results. Five RCTs with 582 participants were included in the qualitative review, and 4 RCTs with 545 participants were included in the meta-analysis. There was moderate evidence for short-term effects on psychological symptoms (SMD = −0.37; 95% CI −0.67 to −0.07; P = 0.02). No evidence was found for total menopausal symptoms, somatic symptoms, vasomotor symptoms, or urogenital symptoms. Yoga was not associated with serious adverse events. Conclusion. This systematic review found moderate evidence for short-term effectiveness of yoga for psychological symptoms in menopausal women. While more rigorous research is needed to underpin these results, yoga can be preliminarily recommended as an additional intervention for women who suffer from psychological complaints associated with menopause.

Effect of aerobic training on menopausal symptoms--a randomized controlled trial

OBJECTIVE

The aim of this study was to assess whether aerobic training affects menopausal symptoms in recently postmenopausal sedentary women.

METHODS

Symptomatic women aged 45 to 63 years (N = 176; 3-36 months since last menstruation) were randomly assigned to an aerobic training or a control group. The intervention included unsupervised aerobic training for 50 minutes four times weekly for 24 weeks, whereas the control group attended health lectures twice a month. Symptoms were reported twice a day using a mobile phone. The perceived disturbance of menopausal symptoms (night sweats, mood swings, irritability, depressive mood, headache, vaginal dryness, and urinary symptoms) was evaluated on a scale from 1 (low) to 5 (high). Multilevel mixed-effect ordinal regression models were based on 17,000 responses during 24 weeks.

RESULTS

One hundred fifty-four women continued until the end of the study (88% compliance rate). Baseline prevalence was as follows: night sweats, 50% to 60%; irritability and depression, 20% to 25%; mood swings, 25% to 30%; headache and urinary problems, 15% to 20%; and vaginal dryness, 10% to 15%. The prevalence of all symptoms except vaginal dryness decreased among intervention groups. According to multilevel mixed-effect ordinal regression analysis, night sweats and mood swings (P < 0.001) and disturbance of the mood swings (P < 0.001) and irritability (P < 0.001) were reduced more among the women in the intervention group than in the control group.

CONCLUSIONS

In sedentary women, aerobic training for 6 months may decrease the typical menopausal symptoms, especially night sweats, mood swings, and irritability.

Yoga decreases insomnia in postmenopausal women: a randomized clinical trial

OBJECTIVE

The practice of yoga has been proven to have positive effects on reducing insomnia. Studies have also shown its effects on reducing climacteric symptoms. To date, however, no studies that evaluate the effects of yoga on postmenopausal women with a diagnosis of insomnia in a randomized clinical trial have been conducted. The aim of this study was to evaluate the effect of yoga practice on the physical and mental health and climacteric symptoms of postmenopausal women with a diagnosis of insomnia.

METHODS

Postmenopausal women not undergoing hormone therapy, who were 50 to 65 years old, who had an apnea-hypopnea index less than 15, and who had a diagnosis of insomnia were randomly assigned to one of three groups, as follows: control, passive stretching, and yoga. Questionnaires were administered before and 4 months after the intervention to evaluate quality of life, anxiety and depression symptoms, climacteric symptoms, insomnia severity, daytime sleepiness, and stress. The volunteers also underwent polysomnography. The study lasted 4 months.

RESULTS

There were 44 volunteers at the end of the study. When compared with the control group, the yoga group had significantly lower posttreatment scores for climacteric symptoms and insomnia severity and higher scores for quality of life and resistance phase of stress. The reduction in insomnia severity in the yoga group was significantly higher than that in the control and passive-stretching groups.

CONCLUSIONS

This study showed that a specific sequence of yoga might be effective in reducing insomnia and menopausal symptoms as well as improving quality of life in postmenopausal women with insomnia.

How might yoga help depression? A neurobiological perspective

Depression is a prevalent mental health condition worldwide and is the leading cause of disability in adults under the age of 45. Most individuals with major depressive disorder (MDD) report only a 50% decrease in symptoms with the use of the standard allopathic treatments for depression. The mechanisms underlying depression remain poorly understood even though stress and its correlates contribute to multiple aspects of the phenomenology of depression. Thus, stress and depression are clearly linked, as stress may precipitate or exacerbate depressive symptoms and depression may be a cause and/or outcome of acute or chronic stress. Therefore, use of additional therapeutic approaches to address stress and depression, such as complementary therapies including yoga, may contribute importantly to symptom reduction. Based on an emerging picture of how stress and mood are regulated within the nervous system, and considering the Executive Homeostatic Network concept that we have recently advanced, we provide an integrative overview of biological mechanisms and substrates that may mediate depression, which should be targets for research to evaluate how the practice of yoga can mitigate depressive symptomatology.

Effect of yoga on menopausal symptoms

OBJECTIVES

To observe the effect of yoga on menopausal symptoms using a prospective, randomized, controlled and interventional study. Main outcome measures Total Menopause Rating Scale (MRS) score and three subscale scores (somatovegetative, psychological and urogenital) were measured on day 1 and day 90 in the study group which performed yoga (asana, pranayam and meditation) under supervision for three months, and were compared with the control group that did not perform yoga. MRS has been designed to measure health-related quality of life of ageing women. It consists of 11 symptoms and three subscales.

RESULTS

It was observed that on day 1 the scores in both the groups were comparable. On day 90, the scores in the yoga group showed a reduction in score on all the subscales, which was statistically significant. No significant difference was noted in the control group.

CONCLUSION

Yoga is effective in reducing menopausal symptoms and should be considered as alternative therapy for the management of menopausal symptoms.

Hot flashes: a review of pathophysiology and treatment modalities

Many therapies are being studied for the treatment of hot flashes for individuals with cancer, yet few studies have demonstrated safe and effective clinical benefit for those who suffer from this distressing symptom. The purpose of this paper is to assess the current options for the management of hot flashes, examining key endpoints from recent clinical trials and reviewing future directions. Hot flashes are a common stressful symptom for individuals with cancer, particularly women with a history of breast cancer and men with prostate cancer. Lifestyle modifications are proposed as the first step in the management of less severe hot flashes. Several publications have addressed nonhormonal agents as a treatment option for hot flashes. Newer antidepressant and anticonvulsant agents have been studied and show potential in treating vasomotor symptoms. Although many complementary and alternative therapies, including herbal medications and phytoestrogens, have been studied for the treatment of hot flashes, none are clinically recommended at this time. Additionally, further evidence is needed for supportive exercise such as yoga and relaxation techniques. Acupuncture may warrant further investigation in the reduction and severity of hot flashes in both men and women. Hormonal therapies, including estrogens and progestogens, are the most well-known and efficient agents in alleviating hot flashes; however, the safety of these agents is disputable.

Exercise for vasomotor menopausal symptoms

BACKGROUND

Evidence suggests that many perimenopausal and early postmenopausal women will experience menopause symptoms, hot flushes being the most common. Symptoms caused by fluctuating levels of oestrogen may be alleviated by HRT but there has been a marked global decline in its use due to concerns about the risks and benefits of HRT; consequently many women are now seeking alternatives. As large numbers of women are choosing not to take HRT, it is increasingly important to identify evidence based lifestyle modification interventions that have potential to reduce vasomotor menopausal symptoms.

OBJECTIVES

To examine the effectiveness of any type of exercise intervention in the management of vasomotor menopausal symptoms (hot flushes and night sweats) in perimenopausal and postmenopausal women.

SEARCH STRATEGY

Searches of the following electronic bibliographic databases were performed to identify randomised controlled trials (RCTs): Cochrane Menstrual Disorders and Subfertility Group Specialised trials register; Cochrane Library (CENTRAL) (Wiley Internet interface), MEDLINE (Ovid), EMBASE (Ovid), PsycINFO (Ovid), Science Citation Index and Social Science Citation Index (Web of Science), CINAHL (Ovid) and SPORT Discus. Searches included dates up until 16-24 March 2010.

SELECTION CRITERIA

RCTs in which any type of exercise intervention were compared no treatment/control or other treatments in the management of menopausal vasomotor symptoms in symptomatic perimenopausal/postmenopausal women.

DATA COLLECTION AND ANALYSIS

Six studies were deemed eligible for inclusion. Three authors independently extracted data from eligible studies. Three meta-analyses according to comparator the group were performed.

MAIN RESULTS

In the comparison of exercise versus no treatment/control (three studies), the non-significant effect size Standardised Mean Difference (SMD) for vasomotor symptoms was -0.14 (95% CI: -0.54 to 0.26); SMD was -0.04, -0.25, -0.38. For the analysis of exercise versus HRT (three studies), the non-significant SMD was 0.49 (95% CI: -0.27 to 1.26); SMD across studies was 0.13, 0.19 and 1.52, with all studies favouring HRT. In the comparison of exercise versus yoga (two studies), the non-significant SMD was -0.09 (95%CI:-0.64 to 0.45); SMD was -0.37 and 0.19. All comparisons were based on small samples. One small study reported data that could not be included in the meta-analysis; in this study hot flush scores were significantly lower in the exercise plus soy milk group (83%) than soy milk only group (72%).

AUTHORS' CONCLUSIONS

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.

A randomised controlled trial of a cognitive behavioural intervention for women who have menopausal symptoms following breast cancer treatment (MENOS 1): trial protocol

Background

This trial aims to evaluate the effectiveness of a group cognitive behavioural intervention to alleviate menopausal symptoms (hot flushes and night sweats) in women who have had breast cancer treatment. Hot flushes and night sweats are highly prevalent but challenging to treat in this population. Cognitive behaviour therapy has been found to reduce these symptoms in well women and results of an exploratory trial suggest that it might be effective for breast cancer patients. Two hypotheses are tested:

Compared to usual care, group cognitive behavioural therapy will:

1. Significantly reduce the problem rating and frequency of hot flushes and nights sweats after six weeks of treatment and at six months post-randomisation.

2. Improve mood and quality of life after six weeks of treatment and at six months post-randomisation.

Methods/Design

Ninety-six women who have completed their main treatment for breast cancer and who have been experiencing problematic hot flushes and night sweats for over two months are recruited into the trial from oncology and breast clinics in South East London. They are randomised to either six weekly group cognitive behavioural therapy (Group CBT) sessions or to usual care. Group CBT includes information and discussion about hot flushes and night sweats in the context of breast cancer, monitoring and modifying precipitants, relaxation and paced respiration, stress management, cognitive therapy for unhelpful thoughts and beliefs, managing sleep and night sweats and maintaining changes.

Prior to randomisation women attend a clinical interview, undergo 24-hour sternal skin conductance monitoring, and complete questionnaire measures of hot flushes and night sweats, mood, quality of life, hot flush beliefs and behaviours, optimism and somatic amplification. Post-treatment measures (sternal skin conductance and questionnaires) are collected six to eight weeks later and follow-up measures (questionnaires and a use of medical services measure) at six months post-randomisation.

Discussion

MENOS 1 is the first randomised controlled trial of cognitive behavioural therapy for hot flushes and night sweats that measures both self-reported and physiologically indexed symptoms. The results will inform future clinical practice by developing an evidence-based, non-medical treatment, which can be delivered by trained health professionals.

Management of menopause-associated vasomotor symptoms: Current treatment options, challenges and future directions

Hot flashes are one of the most common and distressing symptoms associated with menopause, occurring in more than 75% of postmenopausal women. They are especially problematic in breast cancer patients since some breast cancer therapies can induce hot flashes. For mild hot flashes, it is proposed that behavioral modifications are the first step in management. Hormonal therapies, including estrogens and progestogens, are the most well known effective agents in relieving hot flashes; however, the safety of these agents is controversial. There is an increasing amount of literature on nonhormonal agents for the treatment of hot flashes. The most promising data regard newer antidepressant agents such as venlafaxine, which reduces hot flashes by about 60%. Gabapentin is another nonhormonal agent that is effective in reducing hot flashes. While many complimentary therapies, including phytoestrogens, black cohosh, and dehydroepiandrosterone, have been explored for the treatment of hot flashes; none can be recommended at this time. Furthermore, there is a lack of strong evidence to support exercise, yoga, or relaxation for the treatment of hot flashes. Paced respirations and hypnosis appear to be promising enough to warrant further investigation. Another promising nonpharmacological therapy, currently under investigation, involves a stellate ganglion block.

Yoga and menopausal transition

With increased life expectancy, today, women spend one-third of their life after menopause. Thus more attention is needed towards peri- and post-menopausal symptoms. Estrogen replacement therapy is the most effective treatment, however, it has its own limitations. The present need is to explore new options for the management of menopausal symptoms. Yogic life style is a way of living which aims to improve the body, mind and day to day life of individuals. The most commonly performed Yoga practices are postures (asana), controlled breathing (pranayama), and meditation (dhyana). Yoga has been utilized as a therapeutic tool to achieve positive health and control and cure diseases. The exact mechanism as to how Yoga helps in various disease states is not known. There could be neuro-hormonal pathways with a selective effect in each pathological situation. There have been multiple studies that have combined the many aspects of Yoga into a general Yoga session in order to investigate its effects on menopausal symptoms. Integrated approach of Yoga therapy can improve hot flushes and night sweats. There is increasing evidence suggesting that even the short-term practice of Yoga can decrease both psychological and physiological risk factors for cardiovascular disease (CVD). Studies conclude that our age old therapy, Yoga, is fairly effective in managing menopausal symptoms.

The health benefits of yoga and exercise: a review of comparison studies

OBJECTIVES

Exercise is considered an acceptable method for improving and maintaining physical and emotional health. A growing body of evidence supports the belief that yoga benefits physical and mental health via down-regulation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS). The purpose of this article is to provide a scholarly review of the literature regarding research studies comparing the effects of yoga and exercise on a variety of health outcomes and health conditions.

METHODS

Using PubMed((R)) and the key word "yoga," a comprehensive search of the research literature from core scientific and nursing journals yielded 81 studies that met inclusion criteria. These studies subsequently were classified as uncontrolled (n = 30), wait list controlled (n = 16), or comparison (n = 35). The most common comparison intervention (n = 10) involved exercise. These studies were included in this review.

RESULTS

In the studies reviewed, yoga interventions appeared to be equal or superior to exercise in nearly every outcome measured except those involving physical fitness.

CONCLUSIONS

The studies comparing the effects of yoga and exercise seem to indicate that, in both healthy and diseased populations, yoga may be as effective as or better than exercise at improving a variety of health-related outcome measures. Future clinical trials are needed to examine the distinctions between exercise and yoga, particularly how the two modalities may differ in their effects on the SNS/HPA axis. Additional studies using rigorous methodologies are needed to examine the health benefits of the various types of yoga.

Mind-body therapies for menopausal symptoms: a systematic review

OBJECTIVE

To systematically review the peer-reviewed literature regarding the effects of self-administered mind-body therapies on menopausal symptoms.

METHODS

To identify qualifying studies, we searched 10 scientific databases and scanned bibliographies of relevant review papers and all identified articles. The methodological quality of all studies was assessed systematically using predefined criteria.

RESULTS

Twenty-one papers representing 18 clinical trials from 6 countries met our inclusion criteria, including 12 randomized controlled trials (N=719), 1 non-randomized controlled trial (N=58), and 5 uncontrolled trials (N=105). Interventions included yoga and/or meditation-based programs, tai chi, and other relaxation practices, including muscle relaxation and breath-based techniques, relaxation response training, and low-frequency sound-wave therapy. Eight of the nine studies of yoga, tai chi, and meditation-based programs reported improvement in overall menopausal and vasomotor symptoms; six of seven trials indicated improvement in mood and sleep with yoga-based programs, and four studies reported reduced musculoskeletal pain. Results from the remaining nine trials suggest that breath-based and other relaxation therapies also show promise for alleviating vasomotor and other menopausal symptoms, although intergroup findings were mixed. Most studies reviewed suffered methodological or other limitations, complicating interpretation of findings.

CONCLUSIONS

Collectively, findings of these studies suggest that yoga-based and certain other mind-body therapies may be beneficial for alleviating specific menopausal symptoms. However, the limitations characterizing most studies hinder interpretation of findings and preclude firm conclusions regarding efficacy. Additional large, methodologically sound trials are needed to determine the effects of specific mind-body therapies on menopausal symptoms, examine long-term outcomes, and investigate underlying mechanisms.

Yoga for menopausal symptoms: a systematic review

OBJECTIVE

The aim of this study was to assess the effectiveness of yoga as a treatment option for menopausal symptoms.

METHODS

We searched the literature using 14 databases from their inception to July 2008 and included all types of clinical studies regardless of their design. The methodological quality of all studies was assessed using a modified Jadad score.

RESULTS

Seven studies met our inclusion criteria. Two randomized clinical trials compared the effects of yoga with those of walking or physical exercise. The meta-analysis of these data failed to show specific effects of yoga on menopausal complaints including psychological, somatic, and vasomotor symptoms. Two randomized clinical trials found no effects of yoga on total menopausal symptoms compared with wait-list control or no treatment. The remaining studies were either non-randomized (n = 1) or uncontrolled clinical trials (n = 3). They reported favorable effects of yoga on menopausal symptoms. These data collectively show that the results of rigorous studies of the effects of yoga for menopausal symptoms are unconvincing.

CONCLUSION

The evidence is insufficient to suggest that yoga is an effective intervention for menopause. Further research is required to investigate whether there are specific benefits of yoga for treating menopausal symptoms.

Advances in the Treatment of Menopausal Symptoms

Vasomotor symptoms and vaginal atrophy are both common menopausal symptoms. Hormone therapy is currently the only FDA-approved treatment for hot flashes. Current recommendations are to use the lowest dose of hormone therapy for the shortest period that will allow treatment goals to be met. Although the reanalysis of the WHI in 2007 by Roussow et al. provided evidence of coronary heart safety for users of hormone therapy under the age of 60 years and within 10 years of the onset of menopause, not all women desire or are candidates for hormone therapy. In this review we present an evidence-based discussion considering the effectiveness of hormonal and nonhormonal therapies for the relief of vasomotor symptoms and vaginal atrophy. Concern exists regarding systemic absorption of vaginal estrogen and possible adverse effects on the breast and uterus. Selective estrogen receptor modulators and estrogen agonists offer benefits through targeted estrogen agonist/antagonistic effects and are being evaluated with and without estrogen for symptomatic menopausal women. Centrally acting nonhormonal therapies that are effective for the relief of vasomotor symptoms include various antidepressants, gabapentin and clonidine. A limited number of clinical trials have been conducted with nonprescription remedies, including paced respiration, yoga, acupuncture, exercise, homeopathy and magnet therapy, and some, but not all of these, have been found to be more effective than placebo. Dietary herbal supplements, such as soy and black cohosh, have demonstrated mixed and inconclusive results in placebo-controlled trials. Potential therapies for vasomotor symptoms and vaginal atrophy require randomized, placebo-controlled trials of sufficient duration to establish efficacy and safety. Agents under investigation for vasomotor symptoms relief include neuroactive agents, such as gabapentin and desvenlafaxine; an estrogen receptor-β-targeted herbal therapy, MF-101; and the selective estrogen receptor modulator, bazedoxifene, paired with estrogen.

Exercise for vasomotor menopausal symptoms

BACKGROUND

Evidence suggests that a high proportion of perimenopausal and early postmenopausal women will experience some menopause symptoms, hot flushes being the most common. The effects caused by falling levels of estrogen may be alleviated by hormone replacement therapy (HRT) but there has been a marked global decline in the prescription and use of HRT due to concerns about the risks and benefits of HRT; consequently many women are now seeking alternatives. As large numbers of women are choosing not to take HRT, it is increasingly important to identify evidence based lifestyle modifications, which can have a positive effect on menopausal symptoms.

OBJECTIVES

To examine the effectiveness of any type of exercise intervention in the management of vasomotor menopausal symptoms (hot flushes and night sweats) in perimenopausal and postmenopausal women.

SEARCH STRATEGY

Searches of the following electronic bibliographic databases were performed to identify randomised controlled trials: The Cochrane Library (CENTRAL) (Wiley Internet interface) 2006 Issue 2, MEDLINE (Ovid) 1966-May week 4 2006, EMBASE (Ovid) 1980-week 21 2006, PsycINFO (Ovid) 1967-May week 5 2006, Science Citation Index and Social Science Citation Index (Web of Science) 1900-June 2006 and 1956-June 2006 respectively, CINAHL (Ovid) 1982-May week 4 2006, SPORT Discus (ERL WebSPIRS) 1830-2006/04.

SELECTION CRITERIA

Randomised controlled trials (RCTs) in which any type of exercise intervention was compared to other treatments or no treatment in the management of menopausal vasomotor symptoms in symptomatic perimenopausal and postmenopausal women.

DATA COLLECTION AND ANALYSIS

Nineteen reports were deemed potentially eligible, but of these only one met the inclusion criteria and three authors independently extracted data from this trial.

MAIN RESULTS

Only one very small trial, which compared exercise with HRT, was available for inclusion in this review. Based on within-group analyses the study authors concluded that both interventions were effective in reducing vasomotor symptoms. Between-group trial analyses conducted by reviewers showed that the HRT group experienced significantly fewer hot flushes compared to the exercise group at follow-up.

AUTHORS' CONCLUSIONS

Only one very small trial involving symptomatic women has assessed the effectiveness of exercise in the management of vasomotor menopausal symptoms. Exercise was not as effective as HRT in this trial. We found no evidence from randomised controlled trials on whether exercise is an effective treatment relative to other interventions or no intervention in reducing hot flushes and or night sweats in symptomatic women. No conclusions regarding the effectiveness of exercise as a treatment for vasomotor menopausal symptoms could be made due to a lack of trials.
