Non-hormonal treatments for menopausal symptoms

Increasing numbers of women are requesting non-hormonal treatments for menopausal symptoms. Estrogen-containing HRT is the most effective treatment for menopausal symptoms in healthy women but is contraindicated for some women and avoided by many others. This review will assess the evidence regarding the safety and efficacy of non-hormonal treatments for menopausal symptoms. Relatively few high quality studies have addressed this issue, almost all have only addressed the treatment of hot flushes and there are few long-term data.     

Aerobic exercise as a treatment for vasomotor menopausal symptoms: Randomised controlled trial protocol

Background

Evidence suggests that a high proportion of perimenopausal and postmenopausal women experience vasomotor symptoms (hot flushes/night sweats) that can be severe and disruptive and which are the principal reason for seeking medical intervention. Hormone therapy (HT) is known to be an effective treatment for troublesome hot flushes/night sweats but research has raised questions about the safety of HT and there have been negative high profile media reports about its use. Consequently many women are seeking alternatives and exercise might be one such option but there is a lack of high quality evidence on its effectiveness.

Aims

This RCT initially aims to investigate the feasibility/acceptability of two exercise interventions identified from our previous preference study in 165 women, and if found to be feasible/acceptable, continue to recruit sufficient women (n = 261) to examine the effect of these interventions on hot flushes/night sweats and other outcomes relevant to menopausal women.

Method

We aim to recruit inactive perimenopausal and menopausal symptomatic women not using HT and randomise them to one of two exercise interventions or usual care for six months.

Results

We will assess outcomes at baseline and 6 and 12 months from randomisation.

Conclusion

We hope this RCT will contribute towards increasing the evidence regarding the question of whether exercise is an effective treatment for vasomotor symptoms in women not taking HT.

A review of acupuncture for menopausal problems

Acupuncture is one of the complementary therapies that are increasingly used by women with menopausal hot flushes. Acupuncture can be understood as a form of neurological stimulation. Clinical trials of acupuncture use different control groups according to whether they wish to provide practical information on the role of acupuncture in health care, or theoretical information on the specific needle effect. Controls for the latter research question are highly problematic, and no convincingly inert ‘placebo’ needle has yet been designed. For natural menopause, one large study has shown acupuncture to be superior to self-care alone in reducing the number of hot flushes and improving the quality of life; five small studies have been unable to demonstrate that the effect of acupuncture is limited to any particular points, as traditional theory would suggest; and one study showed acupuncture was superior to blunt needle for flash frequency but not intensity. For flushes associated with induced menopause, clearly acupuncture is useful for reducing flushes in clinical practice, but there is mixed evidence on the nature of the effect: one trial found genuine acupuncture superior to control needling, but another showed no significant difference between acupuncture and blunt needle. The possible mechanisms of acupuncture for hot flushes are discussed. Current evidence clearly justifies further research into the most cost effective form of acupuncture for treating hot flushes.     

Symptom prevalence during menopause and factors associated with symptoms and menopausal age. Results from the Norwegian Hordaland Women's Cohort study

Objectives

To describe symptoms during the menopausal transition and age at menopause in a representative Norwegian female cohort over a ten year period, to analyze factors associated with frequency and burden of symptoms and influence on self-rated health.

Study design

2229 women aged 40–44 years at inclusion, randomly selected from a national health survey in Hordaland County, Norway, and followed with seven postal questionnaires from 1997 throughout 2009. Data for 2002 women (90%) were eligible for analyses.

Results

In a longitudinal analysis, 36% of the women reported daily hot flushes in one or more questionnaires, whereas 29% did not experience hot flushes at all. The prevalence of daily hot flushes increased from 2% at age 41–42 to 22% at age 53–54, decreasing to 20% at age 55–57. The odds ratio for reporting daily hot flushes vs. never/seldom for daily smokers was 1.6 (1.24–2.10). Women in the lowest education group had an OR = 1.8 (1.21–2.56) for reporting daily hot flushes compared to women with a university degree. There was no relation between the symptom burden and degree of physical exercise, overall feeling of health, BMI, family income, parity or menarche age as recorded at baseline. The mean age for final menstruation period (FMP) in the cohort was 51.1 (50.9–51.3) years. Smokers had a mean age of FMP 0.9 years earlier compared to the non-smokers.

Conclusions

Daily smoking and educational level were independent risk factors for experiencing daily menopausal symptoms. Degree of physical exercise, BMI, parity or menarche age did not have significant influence.     

Exercise to reduce vasomotor and other menopausal symptoms: A review

Many women are reluctant to consider HRT as a therapeutic option for menopausal symptoms and are keen to use non-pharmacological treatments. Evidence from randomised controlled trials (RCTs) concerning the effects of aerobic exercise on vasomotor and other menopausal symptoms is limited but what evidence we do have suggests that aerobic exercise can improve psychological health and quality of life in vasomotor symptomatic women. In addition, several RCTs of middle-aged/menopausal-aged women have found that aerobic exercise can invoke significant improvements in several common menopause-related symptoms (e.g. mood, health-related QoL and insomnia), relative to non-exercise comparison groups. There is some evidence that alternative forms of low intensity exercise such as yoga are beneficial in reducing vasomotor symptoms and improving psychological well-being in menopausal women. Collectively, these RCTs highlight the broader potential that exercise could have for women during the menopause transition. Whilst both the Royal College of Obstetricians and Gynaecologists in the UK and the North American Menopause Society have recommended that women be advised to consider aerobic exercise as a treatment for vasomotor menopausal symptoms, to make any evidence-based conclusions regarding the effectiveness of exercise in managing these symptoms, more high quality research is needed.     

A pilot study of a Hatha yoga treatment for menopausal symptoms

OBJECTIVE: To assess the feasibility and efficacy of a yoga treatment for menopausal symptoms. Both physiologic and self-reported measures of hot flashes were included. METHODS: A prospective within-group pilot study was conducted. Participants were 12 peri- and post-menopausal women experiencing at least 4 menopausal hot flashes per day, at least 4 days per week. Assessments were administered before and after completion of a 10-week yoga program. Pre- and post-treatment measures included: Severity of questionnaire-rated menopausal symptoms (Wiklund Symptom Check List), frequency, duration, and severity of hot flashes (24-h ambulatory skin-conductance monitoring; hot-flash diary), interference of hot flashes with daily life (Hot Flash Related Daily Interference Scale), and subjective sleep quality (Pittsburgh Sleep Quality Index). Yoga classes included breathing techniques, postures, and relaxation poses designed specifically for menopausal symptoms. Participants were asked to practice at home 15 min each day in addition to weekly classes. RESULTS: Eleven women completed the study and attended a mean of 7.45 (S.D. 1.63) classes. Significant pre- to post-treatment improvements were found for severity of questionnaire-rated total menopausal symptoms, hot-flash daily interference; and sleep efficiency, disturbances, and quality. Neither 24-h monitoring nor accompanying diaries yielded significant changes in hot flashes. CONCLUSIONS: The yoga treatment and study procedures were feasible for midlife women. Improvement in symptom perceptions and well being warrant further study of yoga for menopausal symptoms, with a larger number of women and including a control group.     

Beliefs regarding menopausal hot flushes among climacteric women as assessed with the Hot Flush Beliefs Scale

Background

Hot flushes (HFs) and night sweats are frequent complaints among both peri- and postmenopausal women. Beliefs regarding these complaints may vary from one population to another.

Objective

To assess HF beliefs and factors related to negative beliefs in a climacteric Hispanic population using the Hot Flush Beliefs Scale (HFBS).

Methods

A total of 1154 healthy women (40–59 years) were assessed with the Menopause Rating Scale (MRS), those presenting HFs were requested to fill out the HFBS and a questionnaire containing socio-demographic data (female and partner).

Results

A total of 646 presented HFs (56%) graded according to the first item of the MRS as mild (28.6%), moderate (33.2%), severe (29.1%) and very severe (9.1%). Mean age of these women was 49.5 ± 5.2 years, with 51.9% having 12 or less years of education, 61.5% being postmenopausal and 47.2% living in high altitude. At the moment of the survey 13.9% were on HT, 12.8% on phytoestrogens and 7.1% on psychotropic drugs. Women strongly disagreed in more negatively oriented items of those contained in subscale one (beliefs about self in social context). Contrary to this, women strongly agreed in more negative oriented items contained in subscale two which assesses beliefs about coping with HFs. Women presenting with severe–very severe HFs displayed higher HFBS total and subscale scores indicating a more negative belief regarding HFs. Logistic regression analysis determined that HF severity was related to higher HFBS scores for the total and subscales one and two. Current smoking, higher parity, lower female education, female psychiatric consultation, time since menopause and partner unhealthiness and alcohol consumption were also related to higher HFBS scorings. Postmenopausal status and church attendance were related to lower scores.

Conclusion

In this mid-aged Ecuadorian female series negative beliefs regarding HFs were related to the severity of HFs and individual female or partner characteristics. Data provided from clinical research using this tool, alone or in combination with other tests, is warranted.     

Depressive symptoms and menopausal burden in the midlife

Objective

The goal of this study was to assess whether menopausal symptoms were more common and/or more severe among women with depressive symptoms.

Methods

A cross-sectional survey of 1358 women, ages 45–70, at two large integrated health plans (Seattle; Boston) was performed. Information on demographics, medical and reproductive history, medication use, menopausal experience and depressive symptoms (PHQ-8) were collected. Women taking HT were excluded. Logistic regression models adjusted for age and body mass index tested the associations between menopausal symptoms (hot flushes, night sweats, vaginal dryness and dyspareunia) and presence of moderate/severe depressive symptoms.

Results

770 women were included; 98 (12.7%) had moderate/severe depressive symptoms and 672 (87.3%) had no/mild depressive symptoms. Women with moderate/severe depressive symptoms were almost twice as likely to report recent vasomotor symptoms (hot flashes and or night sweats) vs. women with no/mild depressive symptoms (adjusted odds ratio (aOR) 1.67, 95%CI 1.04–2.68), and to report them as severe (aOR 1.63, 95%CI 0.95–2.83). A higher symptom burden was observed despite the fact that 20% of women with moderate/severe depressive symptoms (vs. 4.6% no/mild depressive symptoms) were using an SSRI or SNRI, medications known to improve vasomotor symptoms. The percentage of women with menopausal symptoms, and the percentage with severe vasomotor symptoms were linearly associated with the depressive symptom score.

Conclusions

Depressive symptoms “amplified” the menopausal experience, or alternatively, severe vasomotor symptoms worsened depressive symptoms.     

Factors relating to insomnia during the menopausal transition as evaluated by the Insomnia Severity Index

Background

Although the menopause associates to poor sleep quality, insomnia severity data in the menopausal transition is scarce or lacking.

Objective

To assess insomnia prevalence, severity and related factors in mid-aged women.

Methods

In this cross-sectional study 340 women (40 to 59 years) completed the Insomnia Severity Index (ISI) and a general questionnaire containing personal/partner data. Hot flush presence and intensity was also assessed with the Menopause Rating Scale (MRS).

Results

Median age of the sample was 48.0 years, with 63.5% having lower education and 52.9% being postmenopausal. At the moment of the survey 7.1% were on hormone therapy, 8.2% on phytoestrogens and 2.1% on psychotropic drugs. A 63.8% were abdominally obese (waist circumference > 88 cm) and 65.5% sedentary. According to item 1 of the MRS, 60.9% presented hot flushes, graded in 17.4% as severe-very severe. Regarding the partner (n = 255), erectile dysfunction was present in 23.9%, premature ejaculation 37.6%, 35.3% abused alcohol and 42.4% were faithful. The ISI tool displayed a high internal consistency (alpha Cronbach coefficient = 0.87), identifying 41.5% of women with some degree of insomnia (Total ISI score ≥8) further categorized as sub-threshold or mild (32.0%), moderate (7.4%) and severe (2.1%). Multiple linear regression analysis obtained two best fit models predicting total ISI scores, one not including and one including partner data. In the first model, hot flush severity, psychotropic use and sedentarism displayed significant positive correlations with total ISI scores. In the second, hot flush intensity, psychotropic drug use and male erectile dysfunction positively correlated whereas partner faithfulness inversely with ISI scores.

Conclusion

In this mid-aged series insomnia severity was related to female and partner factors; several of which are susceptible of intervention.     

Cognitive behaviour therapy for menopausal symptoms following breast cancer treatment: Who benefits and how does it work?

Objectives

Cognitive behaviour therapy (CBT) has been found to reduce the impact of menopausal symptoms, hot flushes and night sweats. This study investigates the moderators and mediators of CBT for women who had problematic menopausal symptoms following breast cancer treatment.

Study design

Analysis of 96 patients with breast cancer induced menopausal symptoms recruited to the MENOS1 trial; 47 were randomly assigned to Group CBT and 49 to usual care. Questionnaires were completed at baseline, 9 and 26 weeks post randomisation. Potential moderators and mediators, including sociodemographic, clinical and psychological factors, of the treatment effect on the primary outcome were examined.

Main outcome measure

Hot Flush Problem Rating.

Results

CBT was effective at reducing problem rating at 9 weeks regardless of age, BMI, time since breast cancer diagnosis, menopausal status at time of diagnosis, or type of cancer treatment (radiotherapy or chemotherapy or endocrine treatment). The treatment effect was significantly greater in women not receiving chemotherapy, those with higher levels of psychological distress at baseline and for non-white women. Beliefs about control/coping with hot flushes were the main mediators of improvement in problem rating following CBT. Beliefs about hot flushes in a social context, depressed mood and sleep problems were also identified as mediators.

Conclusions

These findings suggest that CBT is widely applicable for breast cancer patients who are experiencing treatment related menopausal symptoms, and that CBT works mainly by changing beliefs and improving mood and sleep.     

Sleep quality and aerobic training among menopausal women--a randomized controlled trial

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.     

Factors related to increased daytime sleepiness during the menopausal transition as evaluated by the Epworth Sleepiness Scale

Background

Sleep disorders and sleep-apnea/hypopnea syndromes are very frequent in women, being misdiagnosed in many cases. The menopause, regardless of age, is associated to poor sleep quality and daytime sleepiness that can lead to impaired quality of life, and reduced productivity and functioning.

Objective

To assess daytime sleepiness and related risk factors among middle aged Ecuadorian women using the Epworth Sleepiness Scale (ESS).

Methods

In this cross-sectional study 149 women aged 40–59 years were assessed for hot flush presence and intensity using the Menopause Rating Scale (MRS) and requested to fill out the ESS and a questionnaire containing personal and partner data.

Results

Mean age of surveyed women was 47.6 ± 5.5 years, with 67.8% having less than 12 years of schooling, 33.6% being postmenopausal, and 2.7% on hormone therapy. A 10.1% were current smokers and 20.8% were sedentary. According to the MRS (item 1) 51.7% presented hot flushes, which were graded as severe–very severe in 42.8% of cases. Regarding the partner (n = 132), erectile dysfunction was present in 10.6%, premature ejaculation 6.1% and 17.4% abused alcohol. Mean total ESS score was 8 ± 4.4 (median 8), with 33.6% considered having some degree of daytime sleepiness (ESS score ≥10). Logistic regression analysis determined that postmenopausal status (OR 6.58, CI 95% [2.51–17.23], p = 0.001), sedentarism (OR 3.43, CI 95% [1.14–10.26], p = 0.02) and hot flush presence (OR 2.61, CI 95% [1.02–6.65], p = 0.04) among women were risk factors for increased daytime sleepiness (ESS total score ≥10) whereas partner faithfulness decreased this risk (OR 0.47, CI 95% [0.24–0.90], p = 0.02).

Conclusion

Increased daytime sleepiness in this middle aged series was related to female (hormonal status and sedentarism) and partner factors; several which are susceptible of intervention.     

Internet-delivered applied relaxation for vasomotor symptoms in postmenopausal women: Lessons from a failed trial

Internet-delivered therapies have a short history and promising results have been shown for several health problems, particularly for psychiatric conditions. This study was a first attempt to evaluate whether Internet-delivered applied relaxation for hot flushes in postmenopausal women may be useful. Due to a high drop-out rate the study was prematurely terminated after inclusion of approximately two thirds of calculated women. The Internet-delivered applied relaxation must probably be modified for such populations and settings before it can be used further. This article will discuss the benefits and pitfalls to learn in order to meet the challenges of future studies.Clinical Trial Registration Number: NCT01245907.     

Plasma cortisol concentrations in women with menopausal flushes

A wide variety of stressful stimuli has been shown to increase cortisol secretion. Women with post-menopausal flushes report that their flushes cause acute physical discomfort. We studied the effect of hot flushes on plasma cortisol concentrations in 7 women with frequent post-menopausal flushes. Subjects were monitored subjectively and objectively with a skin temperature recorder over a 3-h period (8:00–11:00 a.m.). The 8:00 a.m. cortisol levels were the highest. These were followed by a decline in plasma levels, suggesting the normal circadian variation in cortisol concentrations. No increase in plasma cortisol levels was found during or after the flush episodes. These results suggest that, in our experimental setting, post-menopausal flushes do not increase cortisol secretion.     

Phytoestrogens for menopausal symptoms: a review

Objective

To review the evidence that isoflavones are effective treatments for menopausal symptoms and to present the safety data.

Methods

The databases Scopus, ScienceDirect and Primo Central Index were searched and preference was given to systematic reviews and meta-analyses.

Results

The available evidence suggests that isoflavones do not relieve menopausal vasomotor symptoms any better than placebo. Long-term safety studies suggest that women who consume a diet high in isoflavones may have a lower risk of endometrial and ovarian cancer.

Conclusions

Isoflavones cannot be recommended for the relief of hot flushes.     

Thermography of menopausal hot flushes

The skin temperature changes associated with menopausal hot flushes have been examined by thermography on a small group of patients. The subjective sensation of heat during a flush seems to be out of proportion to the actual skin temperature increase which was only about 1 degrees C on the face, neck and upper chest during this study. The increased temperature on the cheeks often persisted for several minutes after the symptoms of the flush had subsided, whereas sweating on the forehead produced a more rapid local cooling effect. Sequential temperature changes were portrayed by using an AGA Thermovision Model 680 Medical System with a colour isotherm attachment. This study provided colourful objective evidence that the symptoms of menopausal flushing is associated with an increase of skin temperature which may be monitored by thermography.     

Menopausal symptoms following breast cancer treatment: A qualitative investigation of cognitive and behavioural responses

Objectives

Menopausal symptoms – hot flushes and night sweats (HF/NS) – are particularly troublesome for women who have undergone breast cancer treatment. Non-medical treatments, such as cognitive behaviour therapy, are being developed but there is a lack of information about cognitive and behavioural reactions to HF/NS in breast cancer patients.

Methods

Thirty-five women who had completed active breast cancer treatment with at least 10 HF/NS per week completed questionnaires assessing HF/NS, mood and beliefs, and took part in interviews to elicit cognitive and behavioural reactions and a thematic content analysis used to analyse the data.

Results

The mean weekly frequency of HF/NS was 76 (SD = 46) (57 HF and 19 NS). Smokers reported significantly more night sweats, but BMI and mood were not associated with HF/NS frequency. Cognitive and behavioural responses were varied but broadly similar to those of well women. The main cognitive themes were: embarrassment/social anxiety, loss of control, beliefs about NS, sleep and tiredness, and the main behaviours were: carry on and ignore them, cool down, avoidance, communication with others.

Conclusions

The results are discussed within a cognitive behavioural framework and might inform the development of psychological interventions for these treatment related symptoms.
