Physical activity and risk of vasomotor symptoms in women with and without a history of depression: results from the Harvard Study of Moods and Cycles

The influence of habitual physical activity and sedentary behavior on objective and subjective hot flashes at midlife

OBJECTIVE

The purpose of this study was to evaluate relationships between physical activity, sedentary time, and hot flashes during both waking and sleeping periods using concurrent objective and subjective measures of hot flashes in midlife women.

METHODS

Women aged 45 to 55 years (n = 196) provided self-reported data on physical activity and underwent 24 hours of hot flash monitoring using sternal skin conductance. Participants used event marking and logs to indicate when hot flashes were perceived. Wake and sleep periods were defined by actigraphy. Mean ambient temperature and humidity were recorded during the study period. Generalized linear regression modeling was used to evaluate the effect of physical activity types and sedentary time on hot flash outcomes. Isotemporal substitution modeling was used to study the effect of replacing sedentary time with activity variables on hot flash frequency.

RESULTS

Modeled results indicated that increasing sitting by 1 hour was associated with a 7% increase in the rate of objectively measured but not subjectively reported hot flashes during sleep. Replacing 1 hour of sitting with 1 hour of vigorous activity was associated with a 100% increase in subjectively reported but not objectively measured waking hot flashes. There was little evidence for an effect of temperature or humidity on any hot flash outcome.

CONCLUSIONS

These data provide support for relations between sedentary time, physical activity, and hot flashes and highlight the importance of using objective and subjective assessments to better understand the 24-hour hot flash experience.

Physical activity and exercise for hot flashes: trigger or treatment?

IMPORTANCE AND OBJECTIVE

Hot flashes (HFs) are a prevalent feature of menopause. Hot flashes can be bothersome and affect quality of life. However, HFs have also been associated with the risk for cardiovascular disease. Therefore, providing current evidence on the effect of therapies to reduce HFs can help patients and providers with decision making. This review provides details on the scientific evidence to date related to the effect of physical activity (PA) and exercise to alter the HF experience in women.

METHODS

The PubMed database was searched between June 2020 and June 2022 for currently available evidence regarding the relation between PA and exercise and HFs. Our analysis included randomized control trials on exercise training, epidemiological studies, and studies evaluating acute exercise on the self-reported and objectively measured HF experience in addition to systematic reviews on the topic published as of June 2022.

DISCUSSION AND CONCLUSIONS

The majority of evidence from randomized control trials indicates that aerobic and resistance exercise training lead to a decrease in subjectively experienced HFs. The limited available studies on acute exercise indicate that a bout of moderate-intensity exercise may decrease objectively measured and self-reported HFs but acute increases in PA intensity above accustomed levels may influence subjective HF experience. Some evidence suggests that for those with depression, habitual PA may be an effective way to reduce HF symptoms. Weighing the available evidence, for people who experience HFs, engaging in regular moderate-intensity PA, including aerobic and resistance exercise, may be an effective therapy to reduce HFs and women should be counseled on the benefits of regular, moderate exercise. However, significant gaps in knowledge remain about the optimal exercise prescription, effectiveness for a diverse population, meaning of differences between objective and subjective experience, and mechanisms that lead to changes in HFs.

Predictors of regular physical activity behavior and quality of life in post-menopausal Iranian women based on the multi-theory model

This research aims to identify the predictive factors related to the initiation and sustaining of regular physical activity behaviors and their influence in adapting to menopausal symptoms. The study uses the multi-theory model (MTM) as the conceptual framework. The descriptive cross-sectional research was conducted on 200 post-menopausal women aged 45-55 years. All participants were referred to health centers, where they completed a three-part questionnaire involving: demographic information, a questionnaire on the influence of regular physical activity on the onset and sustaining of menopause using the MTM, and a standard questionnaire of menopausal quality of life. Data were collected, managed, and analyzed using SPSS 20 and AMOS 23 software. This study reveals that behavioral confidence and changes in the physical environment with coefficients of 0.55 and 0.14 respectively had a direct and significant impact on the initiation of regular physical activity-related behaviors during menopause. The construct of participatory dialogue had no significant impact on the initiation of regular physical activity-related behaviors and menopause. Regarding the sustainability of regular physical activity, the emotional transformation construct with a coefficient of 0.73 and change in social environment construct with a coefficient of 0.11 directly and significantly impact keeping regular physical activity behaviors due to menopause. Therefore, interventions based on the MTM can prove very useful for this specific population. In addition, the use of constructs validated by this study will especially be useful in producing evidence-based intervention for the target population.

Effect of the fourth generation multi-theory model intervention on the quality of life in Iranian postmenopausal women: A randomized controlled trial

OBJECTIVES

Menopause is a natural part of women's lives and is associated with a series of complications that can impair their quality of life. This study was conducted to determine the effect of specific educational interventions on the quality of life among postmenopausal women.

METHODS

This randomized controlled trial was conducted on 80 menopausal women who met the inclusion and exclusion criteria and were selected through the multi-stage stratified random sampling method. The participants were randomly allocated to either the control or intervention group (40 per group). The intervention comprised 5 × 45-min educational sessions based on the Multi-Theory Model on the predetermined days of the week. The scores of the quality of life level were collected at baseline, immediately, and 3 months after the intervention using the Menopause-Specific Quality of Life questionnaire (MENQOL). The control group received a health advice.

RESULTS

Analysis of variance of repeated measures showed a significant interaction between time and intervention. The comparison between the mean score of quality of life of the "before," "immediately after intervention," and "3 months after the intervention" showed a significant difference between the two groups. The intervention group quality of life improved significantly as the intervention went on compared to the control group.

CONCLUSION

Structured simple educational programs based on the Multi-Theory Model could be used as a simple and noninvasive intervention that help menopausal women improve their quality of life through menopausal symptoms relief. Further interventions with larger trials may be required to confirm these findings.

Effect of An Online Physical Activity Promotion Program and Cardiovascular Symptoms Among Asian American Women at Midlife

Despite an increasing number of online programs to promote physical activity, they have rarely been evaluated for their effects on cardiovascular symptoms of racial/ethnic minority women at midlife. This study aimed to determine the preliminary efficacy of a newly developed online program for physical activity promotion on cardiovascular symptoms of Asian American midlife women. This study was a pilot repeated-measures randomized controlled trial (pretest/posttest) among 26 Asian American midlife women. The variables were measured using multiple instruments on background features, physical activity, and cardiovascular symptoms at three points of time (baseline, after 1 month, and after 3 months). Linear mixed models were used to analyze the data. The prevalence and severity of cardiovascular symptoms did not show a statistically significant group-time interaction. However, the increase in lifestyle physical activity over time was significant only among the intervention group (Δ = 0.49, P = .016). The results supported the program's preliminary efficacy on lifestyle physical activity for Asian American women at midlife, but not on cardiovascular symptoms.

Depression and Menopause: An Update on Current Knowledge and Clinical Management for this Critical Window

Windows of vulnerability for depression have been associated with increased sensitivity to hormonal changes experienced by some women during the luteal phase, postpartum, and/or menopause. Increased awareness has resulted in greater adoption of screening tools for mood and behavioral changes and tailored therapies. This article discusses study results and controversies surrounding therapies uniquely designed for menopause-related depression.

Onset of the Menopause Transition: The Earliest Signs and Symptoms

Although more than 80% of women experience some degree of psychological or physical symptoms around menopause, both women and clinicians have misconceptions about how hormonal changes relate to menopausal symptoms and psychological conditions. Recently, several large-scale, longitudinal studies have been conducted to better characterize symptoms and changes that occur around menopause. This article offers current evidence for symptoms that occur in the early menopause transition, including vasomotor symptoms, mood changes, sleep problems, and changes in sexual functioning.

Improving menopausal symptoms through promoting physical activity: a pilot Web-based intervention study among Asian Americans

OBJECTIVE

Based on previous studies, a Web-based physical activity promotion program with educational modules on menopausal symptoms and physical activity has been developed for Asian American midlife women to reduce their menopausal symptoms through increasing their physical activity. The purpose of this pilot randomized intervention study was to determine the efficacy of the Web-based program in improving menopausal symptom experience of Asian American midlife women.

METHODS

This was a randomized repeated measures pretest/posttest (pretest, post 1 month, and post 3 months) control group study among 29 Asian American midlife women. Multiple instruments were used, including the Midlife Women's Symptom Index and the Kaiser Physical Activity Survey. The data were analyzed using a mixed-model growth curve analysis.

RESULTS

Over time, total severity scores decreased for the control group (-0.53, P < 0.10), whereas they did not exhibit a meaningful change for the intervention group. Both study groups experienced improvement in active living habits over time, but such an improvement was greater for the intervention group (β = 0.29, P < 0.001) than for the control group (β = 0.08, P < 0.10). The time × group interactions for total severity scores were not statistically significant anymore after controlling for physical activity (-0.34 for the control group, P = 0.10).

CONCLUSIONS

The findings supported the feasibility of a 3-month Web-based intervention for menopausal symptom management among Asian American midlife women and the preliminary efficacy of the program in increasing their physical activity.

Sedentary lifestyle in middle-aged women is associated with severe menopausal symptoms and obesity

OBJECTIVE

The aim of the study was to evaluate the association between sedentary lifestyle and the severity of menopausal symptoms and obesity in middle-aged women.

METHODS

The Menopause Rating Scale, the Goldberg Anxiety and Depression Scale, and the Athens Insomnia Scale were administered to 6,079 Latin American women aged 40 to 59 years. Sedentary lifestyle was defined as fewer than three weekly, 30-minute periods of physical activity.

RESULTS

Sedentary women had more severe menopausal symptoms (total Menopause Rating Scale score: 9.57 ± 6.71 vs 8.01 ± 6.27 points, P < 0.0001) and more depressive symptoms (Goldberg), anxiety (Goldberg), and insomnia (Athens Scale) compared with non-sedentary women. They also had greater mean waist circumference (86.2 ± 12.3 vs 84.3 ± 1.8 cm, P < 0.0001) and a higher prevalence of obesity (20.9% vs 14.3%, P < 0.0001). Logistic regression analysis showed that both obesity (odds ratio [OR] 1.52; 95% CI, 1.32-1.76) and severe menopausal symptoms (OR 1.28; 95% CI, 1.06-1.53), including insomnia and depressive mood, were positively associated with a sedentary lifestyle. Having a stable partner (OR 0.85; 95% CI, 0.76-0.96), using hormone therapy (OR 0.75; 95% CI, 0.64-0.87) and having a higher educational level (OR 0.66; 95% CI, 0.60-0.74) were negatively related to sedentary lifestyle.

CONCLUSIONS

There was a high prevalence of sedentary lifestyle in this middle-aged Latin American female sample which was associated with more severe menopausal symptoms and obesity.

Depression and Menopause: Current Knowledge and Clinical Recommendations for a Critical Window

Depression is a disabling condition, which often leads to significant personal, societal, and economic costs. Windows of vulnerability for depression in women likely are associated with an increased sensitivity experienced by some women to changes in the hormonal milieu that occur during the luteal phase of their cycles, during the postpartum period, and/or during the menopause transition. The controversy surrounding a menopause-related depression has been fueled by conflicting methodologies used to characterize reproductive staging or assess psychiatric conditions during midlife years.

Daily physical activity and hot flashes in the Study of Women's Health Across the Nation (SWAN) Flashes Study

OBJECTIVE

To examine the role of physical activity in menopausal hot flashes.

DESIGN

Physiologic hot flash monitor and activity monitor over two 48-hour periods, with self-report in an electronic diary.

SETTING

Community.

PATIENT(S)

51 midlife women.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Physiologically detected hot flashes and reported hot flashes with and without physiologic corroboration.

RESULT(S)

Competing models conceptualize physical activity as a risk or protective factor for hot flashes, but few studies have examined this relationship prospectively using physiologic measures of hot flashes and physical activity. When physiologic hot flashes, reported hot flashes, and reported hot flashes without physiologic corroboration were related to activity changes using hierarchic generalized linear modeling, adjusting for potential confounders, hot flash reports without physiologic corroboration were more likely after activity increases, particularly among women with higher levels of depressive symptoms. No other types of hot flashes were related to physical activity.

CONCLUSION(S)

Acute increases in physical activity were associated with increased reporting of hot flashes that lacked physiologic corroboration, particularly among women with depressive symptoms. Clinicians should consider the role of symptom perception and reporting in relations between physical activity and hot flashes.

To exercise, or, not to exercise, during menopause and beyond

Menopausal symptoms in women can be severe and disruptive to overall quality of life. Hormone replacement therapy, is known to be effective in ameliorating symptoms, however, reporting of side effects has resulted in alternative treatment options. Exercise has been assessed as an alternative treatment option for alleviating menopausal symptoms, including, psychological, vasomotor, somatic and sexual symptoms. Here we report the effects of physical activity and exercise on menopause symptoms in menopausal women.

Factors that may influence the experience of hot flushes by healthy middle-aged women

BACKGROUND

Interest in menopausal symptoms in general and hot flushes (HFs) in particular has grown in recent years. This is mostly due to increased awareness and the vast impact these symptoms have on women's lives. Despite the high prevalence of women who experience HFs, a definitive etiology for HFs is yet to be found. Our objective was to review the current literature dealing with associated factors for experiencing HFs and to provide a synthesized overview on this common and often debilitating condition.

METHODS

We systematically searched the English-language literature in the PubMed database using relevant key words and included only those articles that contained information on associated factors for HFs in generally healthy midlife women.

RESULTS

Both conflicting scientific results between studies documenting factors that influence HFs and the lack of validated measuring tools make it difficult to truly pinpoint associated factors for HFs. Nonetheless, we identified the following clusters of associated factors: the menopausal stages, sex steroid hormones, other endocrine agents, genetic polymorphisms, race/ethnicity, body mass index (BMI) and obesity, mood disorders, smoking, soy isoflavones and phytoestrogens, alcohol consumption, and physical activity.

CONCLUSIONS

No single associated factor was consistently identified as having a major role in experiencing HFs. More resources should be directed to develop a unified study system along with multivariable analyses to get a better understanding of this condition, which often imposes a tremendous social and personal toll on the women who experience it.

Menopause and age-driven changes in blood level of fat- and water-soluble vitamins

OBJECTIVE

The purpose of this cross-sectional study was to assess the association of the menopausal transition with changes in vitamins.

METHODS

The study group comprised women aged 17-85 years from the Third National Health and Nutrition Examination Survey (NHANES), which was conducted between 1988 and 1994, and from the NHANES surveys conducted between 1999 and 2006. Menopausal status was defined using the time since the last period, < 2, 2-12, and > 12 months, for the pre-, peri-, and postmenopause, respectively. The data-cleaning technique employing serum follicle stimulating hormone activity resulted in pre-, peri- and postmenopausal samples encompassing the following age brackets: 17-50, 42-51, and 46-85 years. Statistical inferences were analyzed using non-parametric techniques.

RESULTS

Significant increases in vitamin A and vitamin E concentrations across all phases of the menopausal transition were observed. There was a gradual decrease in the vitamin C concentration across all stages of the menopause but a fairly stable concentration of vitamin B12. There was a statistically significant increase in vitamin D between the pre- and postmenopause. Body mass index correlated negatively with serum vitamin concentration in the pre- and postmenopause.

CONCLUSIONS

Vitamin A should be supplemented in postmenopausal women to decrease the risk of bone fracture. The daily diet should be supplemented with vitamin B12, to avoid possible neurological symptoms due to vitamin B12 deficiency, and with vitamin D to decrease the risk of developing secondary hyperparathyroidism. Due to an adverse influence on serum vitamin concentration, body mass index should be monitored in pre- and postmenopausal women.

Effectiveness of group and self-help cognitive behavior therapy in reducing problematic menopausal hot flushes and night sweats (MENOS 2): a randomized controlled trial

OBJECTIVE

The aim of this study was to examine the effectiveness of group cognitive behavioral therapy (CBT) and guided self-help CBT in reducing hot flush and night sweat (HF/NS) problem rating at 6 and 26 weeks after randomization.

METHODS

This was a randomized control trial of 140 women having 10 or more problematic HF/NS a week for at least a month. The primary outcome was HF/NS problem rating (1-10) at 6 weeks after randomization. Secondary outcomes were physiologically measured HF/NS at 6 weeks; HF/NS problem rating at 6 weeks; and frequency, mood (Women's Health Questionnaire), and health-related quality of life (General Health Survey Short Form-36) at 6 and 26 weeks. Intention-to-treat analysis was used, and between-group differences were estimated using linear mixed models.

RESULTS

Baseline mean (SD) HF/NS weekly frequency was 63.15 (49.24), and problem rating was 5.87 (2.28). Group and self-help CBT both significantly reduced HF/NS problem rating at 6 weeks-group CBT versus no treatment control (NTC; adjusted mean difference, 2.12; 95% CI, 1.36-2.88; P < 0.001) and self-help CBT versus NTC (adjusted mean difference, 2.08; 95% CI, 1.29-2.86; P < 0.001)-and at 26 weeks-group CBT versus NTC (adjusted mean difference, 1.33; 95% CI, 0.54-2.13; P = 0.001) and self-help CBT versus NTC (adjusted mean difference, 1.19; 95% CI, 0.36-2.02; P = 0.005). Group and self-help CBT significantly reduced night sweat frequency at 6 and 26 weeks. There were improvements in mood and quality of life at 6 weeks and improved emotional and physical functioning for group CBT at 26 weeks.

CONCLUSIONS

These results suggest that CBT delivered in group or self-help format is an effective treatment option for women during the menopause transition and postmenopause with problematic HF/NS.

Fertility (male and female) and Menopause

The impact of oncologic treatments on fertility and menopausal symptoms is often significant for patients with cancer. Surgery, radiation, and chemotherapy can all damage the reproductive organs or the hypothalamic pituitary axis that controls them, impairing fertility and causing hormonally mediated symptoms such as hot flashes.

Understanding these risks and strategies to mitigate them may substantially improve cancer survivorship care. For both female and male patients who desire a future biologic child, there are a variety of fertility preservation techniques that should be considered. For cancer survivors who experience menopausal symptoms, lifestyle changes may be beneficial, and hormonal and nonhormonal pharmacologic agents are well proven to reduce symptom burden.

What factors determine whether a woman becomes depressed during the perimenopause?

Perimenopause has long been associated with psychological distress, both anecdotally and clinically. Research has identified this time as a period of increased risk for both first-episode depression and for depression reoccurrence. However, we know that the majority of women do not experience these difficulties during perimenopause. This review examines the current research literature looking at the factors associated with depression during perimenopause, with a view to identifying those factors which are protective and those factors which predict increased risk. From the literature, it is evident that some women have a hormonal vulnerability to mood disorders. However, this does not account for the phenomenon of perimenopausal depression in and of itself. Rather, there appears to be a complex interplay between hormonal vulnerability, the psychosocial resources one has (coping skills and social support), their overall well-being (exercise and other lifestyle factors) and the demands on their coping resources (stressful life events). The complexity of the relationship between perimenopause and depression means that there is a need to look beyond either as a sole explanation of mood during midlife. Education is required for both general practitioners and for women regarding the individual risks of psychological distress during perimenopause, as well as the knowledge of the life factors which we know to be protective.

Effects of a physical activity governmental health programme on the quality of life of elderly people

Background:

The population ageing occurring worldwide resulted in multiple researches on sedentary ageing and quality of life.

Purpose:

To verify the effects of a physical activity programme on the quality of life (QOL) of elderly individuals served by a governmental health programme.

Design:

Descriptive inquiry research.

Methods:

Randomly distributing 70 elderly individuals in a control group ( n=35; mean±SD 69.80±8.05 years) and an experimental group ( n=35; 68.66±5.93 years) plus QOL evaluation via WHOQOL-Old.

Results:

The experimental group showed significant best results on the post-test by repeated-measures ANOVA on sensorial functioning (Δ%=0.022%, p=0. 0001), social participation (Δ%=0.012%, p=0.013), perceptions of death and dying (Δ%=0.04%, p=0.009), intimacy (Δ%=0.059%, p=0.05), and total score (Δ%=0.001, p=0.000).

Conclusions:

Sensorial functioning, social participation, perceptions of death and dying, and intimacy play an important role in the positive relationship between physical activity and QOL.

Physical activity and health during the menopausal transition

The benefits of regular physical activity are well established, but evidence for a protective effect against the adverse health consequences accompanying the menopausal transition is limited. This article reviews that evidence, concluding that more physical activity is generally associated with fewer somatic and mood symptoms. Physical activity seems to minimize weight gain and changes in body composition and fat distribution experienced at midlife and might attenuate the rapid bone density loss that occurs. Given these benefits, clinicians treating perimenopausal women should encourage their patients to follow guidelines for physical activity (≥150 minutes a week of moderate-intensity activity).

Lifestyle alterations for the amelioration of hot flashes

Hot flashes are a common complaint among women as they transition through menopause. This article reviews the evidence of lifestyle alterations for the amelioration of hot flashes including obesity, exercise, smoking, relaxation techniques, and acupuncture. Further randomized controlled trials regarding these lifestyle alterations are needed to determine their full potential benefits regarding hot flashes.

Effect of exercise combined with phytoestrogens on quality of life in postmenopausal women

BACKGROUND

Postmenopausal women seem to favor alternative therapies such as exercise and phytoestrogens as a substitute for potentially harmful hormone replacement therapy. Based on previous research, we hypothesized that phytoestrogens combined with exercise could have a synergic effect on women's health.

OBJECTIVE

To verify whether phytoestrogens enhance the response to mixed training regarding menopausal symptoms and quality of life in postmenopausal women.

METHODS

From a pool of women participating in a 6-month randomized, controlled exercise study, 21 received a placebo (mean age 58.3 ± 5.4 years, body mass index 29.8 ± 5.1 kg/m(2)) and 19 received phytoestrogen supplements (mean age 60.1 ± 3.4 years; body mass index 30.3 ± 4.6 kg/m(2)). Body weight, fat mass and lean body mass (dual-energy X-ray absorptiometry) were assessed. Quality of life was estimated by the Short Form-36 (SF-36) and Perceived Stress Scale-10 (PSS-10) questionnaires, and menopausal symptoms by the Kupperman index. All measurements were performed before and after the intervention.

RESULTS

Although the Kupperman index and PSS-10 remained unchanged in both groups, the SF-36 Physical Component Summary and almost all the SF-36 subscales (except for role-emotional and mental health) increased only in the exercise group taking phytoestrogens (0.001 < p < 0.04).

CONCLUSION

While phytoestrogens combined with mixed exercise were not sufficient to improve menopausal symptoms, it seemed to be a better strategy than exercise alone to improve the general quality of life in postmenopausal women.

Non-hormonal treatment strategies for vasomotor symptoms: a critical review

Hot flashes (or flushes) are the most commonly reported symptoms during the menopause transition and early postmenopausal years, particularly in Western societies; they affect 60-90% of women and can lead to significant physical discomfort and functional impairment. The emergence of hot flashes and night sweats (also known as vasomotor symptoms [VMS]) coincide with a period in life that is also marked by dynamic changes in hormone and reproductive function that interconnect with the aging process, changes in metabolism, lifestyle behaviours and overall health. Estrogen-based therapies have long been the treatment of choice for women suffering from VMS. More recent concerns over long-term safety of menopausal hormone treatments, however, have led physicians and patients to pursue non-hormonal strategies to alleviate their symptoms. In this article, we review most of the efficacy and safety data on non-hormonal treatments for VMS published over the past 20 years. We discuss the evidence for treating symptomatic women in different clinical scenarios, e.g. VMS with and without concomitant depression or VMS following the use of anti-estrogen therapies. Overall, efficacy data support the use of some psychotropic medications, including selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors and gabapentin. Complementary and alternative methods for VMS also showed limited but promising results, although more definitive studies are warranted. Clinicians should therefore be able to tailor treatment strategies for those who are unable or unwilling to use hormones to alleviate VMS and improve overall functioning and quality of life.

Ventilatory inefficiency in major depressive disorder: a potential adjunct for cardiac risk stratification in depressive disorders?

BACKGROUND

Cardiopulmonary exercise testing (CPET) provides insights into ventilatory, cardiac and metabolic dysfunction in heart and lung diseases and might play a role in cardiac risk stratification in major depressive disorder (MDD).

OBJECTIVE

The VE/VCO(2)-slope indicates ventilatory efficiency and has been applied to stratify the cardiac risk in heart failure (HF). Therefore, the current study was conducted to evaluate and classify ventilatory efficiency and its relationship to physical fitness and disease severity in MDD.

METHODS

Exhaustive incremental exercise testing was completed by 15 female MDD patients and pair matched controls. The ventilatory threshold (VT) and the VE/VCO(2)-slope were assessed. Statistical analyses were conducted by means of MANOVAs and follow-up univariate ANOVAs.

RESULTS

In patients with MDD, significant different relative work rates and oxygen uptakes at the VT in comparison to healthy controls were observed. Furthermore, we found an increased VE/VCO(2)-slope in depressed patients. We additionally report an inverse relationship between the VE/VCO(2)-slope and peak power output as well as peak oxygen uptake solely in patients. We did not observe any association of assessed parameters with disease severity.

CONCLUSION

CPET measures indicate ventilatory inefficiency in patients with MDD. The elevated VE/VCO(2)-slope indicates that patients with MDD need to ventilate significantly more to a given amount of developing CO(2). Further investigations are needed to verify the application of the ventilatory classification system to stratify cardiovascular risk in depressive disorder.

A randomized trial of acupuncture for vasomotor symptoms in post-menopausal women

OBJECTIVE

The goal of this study was to determine whether acupuncture would relieve the vasomotor symptoms of post-menopausal women.

DESIGN

A randomized, single-blind trial.

SETTING

A small city in a rural area of Eastern Oregon.

INTERVENTIONS

Women were recruited into the study from the community by advertising or physician referral. All study subjects were in non-surgical menopause and medically stable. Study subjects were randomly assigned to receive 12 weeks of treatment with either Chinese Traditional Medicine (TCM) acupuncture (n=27) or shallow needle (sham) acupuncture (n=24).

OUTCOME MEASURES

Study participants kept a diary recording their hot flashes each day. At baseline, study participants filled out Greene Climacteric Scales and the Beck Depression and Anxiety Inventories. These same outcomes were also measured at week 4 of treatment and at 1 week and 12 weeks after treatment. The number of hot flashes and the numeric scores on the Climacteric Scales and the Beck inventories were compared between the verum and shallow needling groups using two-way repeated measures.

RESULTS

Both groups of women showed statistically significant improvement on all study parameters. However, there was no difference between the improvement in the shallow needle and verum acupuncture groups. Study subjects were not able to guess which group they had been assigned to.

CONCLUSIONS

This study showed that both shallow needling and verum acupuncture were effective treatments of post-menopausal vasomotor symptoms. Study subjects were not able to distinguish shallow needling from real TCM acupuncture. Shallow needling may have therapeutic effects in itself reducing its utility as a "placebo" control for verum acupuncture. This result is consistent with other published studies.

When, why and for whom there is a relationship between physical activity and menopause symptoms

OBJECTIVES

The relationship between enhanced physical activity and decreased menopause symptoms is equivocal. In this study we sought to better understand this relationship by examining the association of physical activity to different symptom domains and by examining mediating and moderating variables.

STUDY DESIGN

Women participating in a randomized control trial on physical activity were given a menopause symptom measure (MENQOL) at follow-up. Of the 280 women participating, 113 (mean age=52) reported having symptoms they attributed to menopause. Regression analyses were run to examine if change in physical activity predicted fewer symptoms. Exercise self-efficacy was examined as a mediator and depressive symptoms as a moderator.

RESULTS

An increase in physical activity from baseline was found to be related to reporting fewer total menopause symptoms (beta=-0.22, p=.02). When the total menopause symptoms score was examined by domain, increased physical activity was found to be related to reporting fewer general symptoms attributed to menopause (psychosocial (beta=-0.18, p=.05) and physical (beta=-0.23, p=.01)), but had no effect on specific symptoms of menopause (vasomotor and sexual). Exercise self-efficacy was found to mediate the relationship between increased physical activity and total, physical and psychosocial menopause symptoms. Finally, for individuals with high depressive symptoms, those who increased physical activity the most reported fewer sexual symptoms of menopause.

CONCLUSION

This study suggests that physical activity participation is associated with lower general symptom reporting as opposed to specifically impacting menopause symptoms. Further, exercise self-efficacy mediates the relationship between physical activity and general menopause symptoms, suggesting a psychological pathway.

Non-estrogenic approaches for the treatment of climacteric symptoms

Non-estrogenic alternatives for the treatment of climacteric symptoms have their origin lost in history. Recent clinical trial data have shown that lifestyle and diet adjustment have some effect in improving both hot flushes and mood. Over-the-counter phytotherapeutic extracts are very popular and women often try a variety of products before resorting to traditional medicine. Preparations containing isoflavones in variable doses, such as soy extract and red clover, or extracts from evening primrose, Cimifuga racemosa, ginseng and black cohosh are often used for treating the climacteric syndrome. The scientific support for their efficacy certainly does not equal their popularity. The most tested pharmacological alternatives to estrogens are serotonin reuptake inhibitors (SSRIs). All available SSRIs have undergone trials for the relief of hot flushes. In spite of the difference between the compounds in both half-life and engagement of serotonin receptors, they appear to have very similar effectiveness in reducing hot flushes. At their best, SSRIs reduce hot flushes by 50-60%, compared with 80% for estrogen, and their effect appears only in the short term. SSRIs have mood-improving effects that appear to be independent of the effect on hot flushes. When used for the treatment of the climacteric syndrome, SSRIs do not adversely affect libido. Dependence is a major concern in women when offered this type of treatment, but does not appear to be a problem with this class of drugs. Withdrawal symptoms have never been reported in trials for hot flushes but are known to occur when SSRIs are used in the long term. In order to avoid these symptoms, the dose should be tapered slowly. Gabapentin, a drug used for the treatment of neuropathic pain and epilepsy, has shown that, in high doses, it has an efficacy similar to that of estrogen; however, this needs further confirmation.

Current alternative and complementary therapies used in menopause

OBJECTIVE

To determine the efficacy and safety of common complementary and alternative medicine (CAM) therapies used to relieve the menopausal symptoms.

DESIGN

Comprehensive literature search was conducted through the databases Medline, EMBASE, Cochrane, AMED (Allied and Complementary Medicine), NCCAM (The National Centre for Complementary and Alternative Medicine) to identify relevant monographs in English language.

RESULTS

Studies have shown that some therapies such as clonidine, selective serotonin receptor inhibitors (SSRIs) and gabapentin are effective in decreasing the degree and frequency of somatic symptoms in menopause, while phytooestrogens and black cohosh have shown mixed results. Use of Ginseng, evening primrose, Dong Quai or vitamin E appears not to be efficacious for the relieving hot flushes. Other effects of these therapies including possible improvements in mood are yet to be substantiated.

INCLUSION CRITERIA

All available human complementary medicine studies on menopausal women with regard to the relief of menopausal symptoms.

EXCLUSION CRITERIA

Studies not meeting the inclusion criteria, published in languages other than English or animal studies.

CONCLUSION

There is a general lacking of longer-term follow-up beyond the trial lengths of 6-12 weeks in the use of CAM, although women may be taking these medications for many years. Well-designed, randomised control trials are needed to elucidate the true effect of these therapies above the placebo effect.

Estrogen and progestogen use in postmenopausal women: July 2008 position statement of The North American Menopause Society

OBJECTIVE

: To update for both clinicians and the lay public the evidence-based position statement published by The North American Menopause Society (NAMS) in March 2007 regarding its recommendations for menopausal hormone therapy (HT) for postmenopausal women, with consideration for the therapeutic benefit-risk ratio at various times through menopause and beyond.

DESIGN

: An Advisory Panel of clinicians and researchers expert in the field of women's health was enlisted to review the March 2007 NAMS position statement, evaluate new evidence through an evidence-based analysis, and reach consensus on recommendations. The Panel's recommendations were reviewed and approved by the NAMS Board of Trustees as an official NAMS position statement. The document was provided to other interested organizations to seek their endorsement.

RESULTS

: Current evidence supports a consensus regarding the role of HT in postmenopausal women, when potential therapeutic benefits and risks around the time of menopause are considered. This paper lists all these areas along with explanatory comments. Conclusions that vary from the 2007 position statement are highlighted. Addenda include a discussion of risk concepts, a new component not included in the 2007 paper, and a recommended list of areas for future HT research. A suggested reading list of key references is also provided.

CONCLUSIONS

: Recent data support the initiation of HT around the time of menopause to treat menopause-related symptoms; to treat or reduce the risk of certain disorders, such as osteoporosis or fractures in select postmenopausal women; or both. The benefit-risk ratio for menopausal HT is favorable close to menopause but decreases with aging and with time since menopause in previously untreated women.

Menopause and the menopausal transition

Menopause and the menopausal transition present unique preventive health and quality-of-life challenges for women. The number of patients in the menopausal age group is increasing and represents a significant portion of the population. Care of the menopausal patient can be challenging for the caregiver. This chapter reviews the major health care challenges as well as evaluation and treatment of common quality-of-life issues for menopausal patients.

Practical clinical guidelines for assessing and managing menopausal symptoms after breast cancer

BACKGROUND

The purpose of this study was to provide practical, evidence-based guidelines for evaluating and treating common menopausal symptoms following breast cancer.

METHODS

Literature review of the causes, assessment and management of menopausal symptoms in breast cancer patients.

RESULTS

A number of nonhormonal treatments are effective in treating hot flashes. Whether pharmacological treatment is given will depend on the severity of symptoms and on patient wishes. For severe and frequent hot flashes, the best data support the use of venlafaxine, paroxetine and gabapentin in women with breast cancer. Side-effects are relatively common with all these agents. For vaginal dryness, topical estrogen treatment is the most effective but the safety of estrogens following breast cancer is not established. There are limited data on effective treatments for sexual dysfunction during menopause.

CONCLUSION

Menopausal symptoms after breast cancer should be evaluated and managed as warranted using a systematic approach and may benefit from multidisciplinary input.

"It's my hormones, doctor"--does physical activity help with menopausal symptoms?

OBJECTIVE

Many women experience health problems when going through menopause, and these health problems may result in a substantial reduction in quality of life. There are some indications that physical activity may play a role in ameliorating menopausal symptoms, but there is conflicting evidence about this. To assess the relationship between changes in physical activity and self-reported vasomotor, somatic, and psychological symptoms.

DESIGN

Data from the third (2001) and fourth (2004) surveys of the Australian Longitudinal Study on Women's Health were used. Data from 3,330 middle-aged women were included in the analyses. In linear regression models, the relationships between changes in physical activity of at least moderate intensity and total menopausal, vasomotor, somatic, and psychological symptoms were determined.

RESULTS

Physical activity was not associated with total menopausal symptoms, vasomotor or psychological symptoms. A weak association with somatic symptoms (B = -0.003; 95% CI: -0.005 to -0.001) was found. Weight gain was associated with increased total, vasomotor, and somatic symptoms. Weight loss was associated with a reduction in total and vasomotor symptoms.

CONCLUSION

Changes in physical activity were not related to vasomotor or psychological symptoms and only marginally to somatic symptoms. Changes in weight showed a stronger relationship with menopausal symptoms. The relationship between weight change and menopausal symptoms merits further exploration.

Collaborative depression care, screening, diagnosis and specificity of depression treatments in the primary care setting

The identification, referral and specific treatment of midlife patients in primary care who are distressed by mood, anxiety, sleep and stress-related symptoms, with or without clinically confirmed menopausal symptoms, are confounded by many structural issues in the delivery of women's healthcare. Diagnosis, care delivery, affordability of treatment, time commitment for treatment, treatment specificity for a particular patient's symptoms and patient receptiveness to diagnosis and treatment all play roles in the successful amelioration of symptoms in this patient population. The value of screening for depression in primary care, the limitations of commonly used screening instruments relative to culture and ethnicity, and which clinical care systems make best use of diagnostic screening programs will be discussed in the context of the midlife woman. The Sequenced Treatment Alternatives to Relieve Depression (STAR*D) program illustrates the relatively high rate of unremitted patients, regardless of clinical setting, who are receiving antidepressants. Nonmedication treatment approaches, referred to in the literature as 'nonsomatic treatments', for depression, anxiety and stress, include different forms of cognitive-behavioral therapy, interpersonal therapy, structured daily activities, mindfulness therapies, relaxation treatment protocols and exercise. The specificity of these treatments, their mechanisms of action, the motivation and time commitment required of patients, and the availability of trained practitioners to deliver them are reviewed. Midlife women with menopausal symptoms and depression/anxiety comorbidity represent a challenging patient population for whom an individualized treatment plan is often necessary. Treatment for depression comorbid with distressing menopausal symptoms would be facilitated by the implementation of a collaborative care program for depression in the primary care setting.

Ethnicity and vasomotor symptoms in postmenopausal women

OBJECTIVE

To determine if there is a difference in the prevalence of vasomotor symptoms between African American and white postmenopausal women.

METHODS

We conducted a cross-sectional study to evaluate baseline vasomotor symptoms in postmenopausal women enrolled in a randomized, placebo-controlled trial of dietary soy supplements. The Menopause-Specific Quality of Life Questionnaire (MENQOL) vasomotor subscale was used to measure vasomotor symptoms, including hot flashes and night sweats.

RESULTS

In total, 104 African American and 112 white postmenopausal women (mean age 56.8 +/- 5.6 years) were studied. A multiple linear regression analysis, which controlled for differences in body mass index (BMI) and dietary fat intake, showed that race and age were significantly and independently associated with vasomotor symptoms, explaining 10% of the variance (p < 0.001). Being African American and younger age were associated with increased vasomotor symptoms.

CONCLUSIONS

The most prevalent postmenopausal symptoms were vasomotor symptoms, which were more bothersome in African American women compared with white women. Factors associated with vasomotor symptoms included race, BMI, and dietary intake of fat calories. Implications for practice include increasing provider awareness to discuss vasomotor symptoms and the need for treatment in postmenopausal African American women. Further research to increase our understanding of racial differences and associated factors that influence the duration and intensity of vasomotor symptoms experienced by postmenopausal women is needed.

Hot flash severity in hormone therapy users/nonusers across the menopausal transition

OBJECTIVES

The purpose of this study was to examine the pattern of and factors that influence hot flash severity across the menopausal transition (MT) and early postmenopause (PM).

METHODS

Women from the Seattle Midlife Women's Health Study (N=302) provided data for these analyses: at least one annual health questionnaire and a menstrual calendar. A subset of women provided a first morning voided urine specimen from 1997 through 2005. Urine samples were assayed for estrone glucuronide and FSH. Linear mixed effects modeling was used to identify change in hot flash severity scores over time, including the relationship to age, MT-related, psychosocial and lifestyle factors.

RESULTS

Increases in hot flash severity were associated with late transition stage, early postmenopause, use of HRT, duration of early transition stage, age of entry into early PM and level of FSH. Age of entry into early transition and estrone levels were associated with decreased hot flash severity. Not associated with hot flash severity were being in early transition stage, age of entry into or duration of late transition stage and all of the psychosocial (anxiety, stress, depressed mood) and lifestyle variables (BMI, activity level, sleep, alcohol use).

CONCLUSIONS

Variables associated with reproductive aging independently predicted changes in hot flash severity; psychosocial and lifestyle variables did not. The effect of age dropped out when factors associated with reproductive aging were considered. Use of HRT ameliorated but did not eliminate severe hot flashes suggesting that there is room for alternative approaches less likely to cause harm.

Physical activity and mental health outcomes during menopause: A randomized controlled trial

BACKGROUND

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.

PURPOSE

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).

METHODS AND RESULTS

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.

CONCLUSIONS

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.
