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

Sleep During Menopause

Postmenopause is defined retrospectively after 12 consecutive months of amenorrhea. It represents the end of the reproductive period and ovarian failure. A decrease in estrogen leads to several changes in the short and long term. Among the early changes, vasomotor symptoms (hot flashes) are particularly common, occurring in about 70% of women. In addition, there are changes in mood, anxiety, depression, and insomnia. Insomnia occurs in almost 60% of postmenopausal women. Psychosocial aspects may also affect sleep. Proper diagnosis may lead to adequate treatment of sleep disturbances during menopause. Hormonal or other complementary therapies can improve sleep quality.

Acupuncture combined with Chinese herbal medicine in the treatment of perimenopausal insomnia: A systematic review and meta-analysis

BACKGROUND

Perimenopausal insomnia (PMI) is a relatively common menopausal symptom that can cause serious problems for the women themselves and their families. Today, the world is facing the trend and challenges of an aging population. It is reported that about 1.5 million women worldwide enter menopause every year, with sleep disorder identified as a core symptom. The efficacy of acupuncture combined with traditional Chinese medicine for treating PMI has been recognized by patients and doctors.

METHODS

We searched 8 databases to identify 15 randomized controlled trials evaluating the effects of acupuncture combined with traditional Chinese medicine on sleep in patients with PMI compared with Western medicine alone. Subsequently, data extraction and analysis were performed to assess the quality and risk of bias of the study method design, and a meta-analysis of the data was performed.

RESULTS

This study included 15 randomized controlled trials involving 1188 patients with PMI. The results show that acupuncture combined with traditional Chinese medicine seems to be more effective than Western medicine in the treatment of PMI: efficiency (RR: 1.18; 95% CI: 1.08, 1.29; P = .001); the Pittsburgh Sleep Quality Index (PSQI) (WMD: -2.77; 95% CI: 4.15-1.39; P < .0001); follicle-stimulating hormone (FSH) (WMD: -31.45; 95% CI: 42.7-20.2; P < .001) and the Hamilton Anxiety Score (HAMA) (WMD: -2.62, 95% CI: -3.93, -1.32; P < .0001). Compared with western medicine, E2 (WMD: 5.07; 95% CI: 5.78-15.92; P = .36) and LH (WMD: -4.86; 95% CI: 11.5-1.78; P = .151) had no difference.

CONCLUSION

The current analysis results show that acupuncture combined with Chinese medicine seems to have a more positive effect than western medicine alone in improving sleep and FSHF in PMI patients, but no difference has been found in improving E2 and LH. This study provides a basis for acupuncture combined with Chinese medicine to treat PMI. However, due to the higher risk of evaluation in included studies, more rigorous randomized controlled trials and higher quality studies are needed to validate included studies.

Is Burning Mouth Syndrome Associated with Extraoral Dryness? A Systematic Review

Burning mouth syndrome (BMS) is characterized by a persistent intraoral burning sensation, often experienced by postmenopausal women. The etiology of BMS remains partially understood, and consequently, treatments remain suboptimal. Extraoral manifestations of BMS, such as extraoral dryness, are less studied. However, it has been suggested that the identification of the frequency and patterns of extraoral dryness and potential underlying mechanisms are essential to optimize treatment strategies and reduce the burden of disease. Therefore, we conducted this systematic review to provide existing evidence about extraoral dryness in BMS. The guidelines for the conduction and reporting of systematic reviews were followed. An electronic search was conducted in four major databases-PubMed, Web of Science, COCHRANE Library, and EBSCOhost-and the grey literature was assessed through Google Scholar. From each included article, information on extraoral dryness in BMS was extracted, and odds ratios were calculated for extraoral dryness among BMS patients compared with non-BMS controls. The findings demonstrated higher odds of the prevalence of extraoral dryness in BMS, which was found to a high degree in the lips, eyes, skin, and genitalia. The pattern of spread and locations of extraoral dryness propose a potential central mechanism. Based on our findings, we encourage the standardization of the assessment, recording, and reporting of the extraoral characteristics of BMS, including extraoral dryness, which can lead to better management strategies and enhance the quality of life of the affected patients.

Effects of exercise on sleep in perimenopausal women: A meta-analysis of randomized controlled trials

Whether an exercise intervention has significant effects on improving the sleep quality in perimenopausal women is controversial. This review explores different ways of exercise interventions (intervention item, intervention period, intervention frequency, and intervention duration of each time) on the improvement of sleep in perimenopausal women. Based on the PICOS method, two researchers independently searched the PubMed database, Excerpta Medica database (EMBASE), Cochrane Library database, Web of Science (WoS) database, Chinese National Knowledge Infrastructure (CNKI) database, Wanfang database and VIP database, evaluated the literature quality using the Cochrane system evaluation manual, and performed a meta-analysis of the included literature. A total of 12 randomized controlled trials involving 1493 subjects were included in the study. Exercise intervention items included yoga, walking, fitness Qigong, and aerobic exercise. The meta-analysis showed that exercise could effectively improve sleep in perimenopausal women (SMD = -0.44, 95%CI (-0.66, -0.22), P < 0.00001), and had significant effects on the sleep quality and insomnia symptoms in perimenopausal women. Subgroup analysis showed that fitness Qigong with a period of 10 to 12 weeks, a frequency of more than 3 times a week, and a duration of each time of 30 to 60 min was the most effective in improving sleep.

Efficacy and safety of lemborexant in midlife women with insomnia disorder

OBJECTIVE

Insomnia is common in midlife women. The efficacy and safety of lemborexant (LEM), a competitive dual orexin receptor antagonist, was assessed for 12 months in a subgroup of midlife women (age, 40-58 y) from Study E2006-G000-303 (Study 303; SUNRISE-2).

METHODS

This was a randomized, double-blind, placebo (PBO)-controlled (first 6 mo) study of adults with insomnia disorder ( N = 949). During treatment period 1 (TP1), participants received PBO or LEM 5 mg (LEM5) or 10 mg (LEM10). During TP2 (second 6 mo), LEM participants continued their assigned dose; PBO participants were rerandomized to LEM5 or LEM10. Assessments included patient-reported sleep- and fatigue-related measures and treatment-emergent adverse events.

RESULTS

The midlife female subgroup comprised 280 of 949 participants (TP1: PBO, n = 90 of 318 [28.3%]; LEM5, n = 82 of 316 [25.9%]; LEM10, n = 108 of 315 [34.3%]). At 6 months, median changes from baseline in subjective sleep-onset latency (in minutes) were -17.9, -20.7, and - 30.4 for PBO, LEM5, and LEM10 (vs PBO: LEM5, P = not significant; LEM10, P = 0.0310). At 6 months, mean changes from baseline in subjective wake after sleep onset (in minutes) were -37.0 (59.6), -50.1 (74.5), and -54.5 (65.4) for PBO, LEM5, and LEM10 (vs PBO: LEM5 and LEM10, P = not significant), with benefits sustained through 12 months. Greater decreases from baseline (improvement) in Insomnia Severity Index total score and Fatigue Severity Scale total score were seen with LEM versus PBO at 6 months; benefits continued through 12 months. Most treatment-emergent adverse events were mild to moderate in severity.

CONCLUSIONS

Consistent with the total population, subjective sleep parameters improved, and improvement was sustained over time in midlife women. LEM was well tolerated, suggesting that LEM may be a potential treatment option for midlife women with insomnia.

Prevalence of insomnia among the post-menopausal women who suffered from COVID-19 in Bangladesh: A nationwide cross-sectional study

Objectives

The impact of the pandemic on sleeping problems in all age groups has been widely reported, but insomnia in post-menopausal women has been understudied worldwide. The study sought to determine the prevalence and associated factors for insomnia in post-menopausal women who were infected with COVID-19 in Bangladesh.

Material and methods

A cross-sectional telephonic survey was conducted from August to December 2021 among post-menopausal women with a history of COVID-19 infection in Bangladesh. Data on socio-demographic factors, lifestyle and behavioral factors, COVID-19-associated factors, and self-reported pre-existing co-morbidities were collected. A validated scale Insomnia Severity Index (ISI) was applied to assess the level of insomnia . Bivariate and multiple linear regression analyses were performed to assess the associated factors with insomnia.

Results

Of the total 900 participants, the prevalence of insomnia was reported at 70%, with 33.67% moderately severe, 25.11% subthreshold, and 11.22% severe insomnia. Participants with increased ISI scores were significantly more likely to be retired, had 2-4 children, felt disturbed by COVID-19 related news, hospitalized for COVID-19 management, receieved the first dose of vaccine, and experienced post COVID-19 symptoms such as fatigue, lack of concentration, and memory loss. On the other hand, living in a nuclear family and taking care of COVID-19-infected family members were significantly negatively associated with insomnia.

Conclusions

Our findings indicate the need to safeguard the well-being considerations of post-menopausal women through a well-designed comprehensive social safety net program for the present pandemic and similar crises in the future.

Socioeconomic status and sleep health: a narrative synthesis of 3 decades of empirical research

STUDY OBJECTIVES

This review aims to assess the association between socioeconomic status (SES) and sleep health in the general population and the mediating effects of lifestyle and mental and physical health in this relationship.

METHODS

Observational studies testing the independent association between objective or subjective SES indicators and behavioral/physiological or clinical sleep health variables in the general population were included. PubMed/MEDLINE was searched for reports published from January 1990 to December 2019. The direction of effect was used as the primary effect measure, testing the hypothesis that low SES is associated with poor sleep health outcomes. Results are presented in the form of direction effect plots and synthesized as binomial proportions.

RESULTS

Overall, 336 studies were identified. A high proportion of effects at the expected direction was noted for measures of sleep continuity (100% for sleep latency, 50-100% for awakenings, 66.7-100% for sleep efficiency), symptoms of disturbed sleep (75-94.1% for insomnia, 66.7-100% for sleep-disordered breathing, 60-100% for hypersomnia), and general sleep satisfaction (62.5-100%), while the effect on sleep duration was inconsistent and depended on the specific SES variable (92.3% for subjective SES, 31.7% for employment status). Lifestyle habits, chronic illnesses, and psychological factors were identified as key mediators of the SES-sleep relationship.

CONCLUSIONS

Unhealthy behaviors, increased stress levels, and limited access to health care in low-SES individuals may explain the SES-sleep health gradient. However, the cross-sectional design of most studies and the high heterogeneity in employed measures of SES and sleep limit the quality of evidence. Further research is warranted due to important implications for health issues and policy changes.

Effects of Nonpharmacological Interventions on Sleep Quality and Insomnia in Perimenopausal and Postmenopausal Women: A Meta-Analysis

This study aimed to analyze the effects of nonpharmacological interventions on perimenopausal and postmenopausal women with sleep problems. Eight databases (MEDLINE/PubMed, Cochrane Library, EMBASE, CINAHL, and four Korean databases) were searched, from their inception through to 30 November 2021, for randomized controlled trials (RCTs) evaluating the effects of nonpharmacological interventions versus control conditions on sleep quality and insomnia in perimenopausal and postmenopausal women. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and the severity of insomnia was assessed using the Insomnia Severity Index (ISI). In the meta-analysis, corrected standardized mean differences (SMDs; Hedges' g) and 95% confidence intervals (CIs) were calculated as effect measures by applying the random effects model and inverse variant method. Fifteen trials met our inclusion criteria. Nonpharmacological interventions were found to have positive effects on sleep quality, measured with the PSQI (SMD = -1.32; 95% CI = -1.78 to -0.86; p < 0.001), and on the severity of insomnia, measured using the ISI (SMD = -1.11; 95% CI = -1.82 to -0.41; p = 0.002), compared with the control groups. Among perimenopausal and postmenopausal women with sleep problems, nonpharmacological interventions improved sleep quality and reduced the severity of insomnia.

Insomnia in primary care: Considerations for screening, assessment, and management

Insomnia, including insomnia disorder, is a common but often overlooked complaint in primary care settings. It is a risk factor for various medical and psychiatric diagnoses and is associated with substantial health care costs. While cognitive behavioral therapy for insomnia (CBT-I) is the first-line treatment for insomnia disorder, access to CBT-I is limited. This article provides a pragmatic approach to screening, assessment, and treatment of insomnia in the primary care setting, promoting a population health approach. The authors review the role of CBT-I, treatment of comorbid conditions, and pharmacologic recommendations in working with primary care patients with insomnia. In addition, the authors highlight the potential utility of technology in improving access to insomnia care.

Prevalence of Psychosomatic and Genitourinary Syndrome Among Menopausal Women: A Systematic Review and Meta-Analysis

Introduction

The menopausal transition represents the passage from reproductive to non-reproductive life and is characterized by a number of menstrual disturbances. We systematically reviewed the evidence on the prevalence of psychosomatic and genitourinary syndrome among menopausal women and compared the risk of symptoms between premenopausal, perimenopausal, and post-menopausal women.

Methods

We performed a systematic search in MEDLINE, CINAHL, and ScienceDirect through March 2021. Case series/reports, conference papers and proceedings, articles available only in abstract form, editorial reviews, letters of communication, commentaries, systematic reviews, and qualitative studies were excluded. Two reviewers independently extracted and assessed the quality of data using the Joanna Briggs Institute Meta-Analysis. The outcomes were assessed with random-effects model using the Review Manager software.

Results

In total, 29 studies had a low risk of bias and were included in the review. Our findings showed that the pooled prevalence of somatic symptoms in post-menopausal women (52.6%) was higher than in the premenopausal and perimenopausal stages (34.6 and 39.5%, respectively). There was a low prevalence of psychological symptoms in premenopausal women (28.4%). The genitourinary syndrome was highest among post-menopausal women (55.1%), followed by perimenopausal (31.9%) and premenopausal (19.2%) women.

Conclusion

Post-menopausal women have a higher risk of experiencing menopausal symptoms particularly genitourinary syndrome than premenopausal and perimenopausal women. It is pertinent for healthcare professionals to evaluate the symptoms in order to provide them with a better quality of life.

The associations between menopausal symptoms and sleep quality in Spanish postmenopausal women

Objectives: Around the menopause, sleep disturbances frequently occur or worsen and are associated with decreased health quality and physical and psychological problems. The aim of this study was to analyze sleep quality and its association with the impact of menopausal symptoms in Spanish postmenopausal women. Methods: A total of 278 postmenopausal women (age 60.95 ± 8.01 years) participated in this cross-sectional study. The Medical Outcomes Study Sleep Scale (MOS-SS) and the Menopause Rating Scale (MRS) were used to analyze sleep quality and severity of menopausal symptoms, respectively. Anxiety and depression were measured using the Hospital Anxiety and Depression Scale. Results: The linear regression showed that a greater impact of menopausal symptoms (MRS total score) was associated with worse scores regarding sleep adequacy (p < 0.001, R² = 0.056), snoring (p = 0.020, R² = 0.036), awaken short of breath (p < 0.001, R² = 0.089), and quantity of sleep (p < 0.001, R² = 0.075) domains. Anxiety (p < 0.001) and worse somatic symptoms (p = 0.001) were related to greater sleep disturbances (R² = 0.164). We also found relationships of heightened psychological symptoms (p < 0.001) and low physical activity level (p = 0.003) with increased daytime somnolence (R² = 0.064). Finally, higher MRS total score and anxiety levels were associated with worse sleep quality assessed by MOS-SS Sleep Problems Index I (R² = 0.179, p < 0.001 and p = 0.001, respectively) and Sleep Problems Index II (R² = 0.146, p < 0.001 and p = 0.011, respectively). Conclusions: Anxiety and severity of menopausal symptoms were associated with poorer sleep quality. Furthermore, low physical activity level and worse psychological symptoms in menopause were predictors for increased somnolence. Therefore, screening for these factors in postmenopausal women is important, since they may be susceptible for intervention.

Sleep problems during the menopausal transition: prevalence, impact, and management challenges

A substantial number of women experience sleep difficulties in the approach to menopause and beyond, with 26% experiencing severe symptoms that impact daytime functioning, qualifying them for a diagnosis of insomnia. Here, we review both self-report and polysomnographic evidence for sleep difficulties in the context of the menopausal transition, considering severity of sleep complaints and links between hot flashes (HFs) and depression with poor sleep. Longitudinal population-based studies show that sleep difficulties are uniquely linked with menopausal stage and changes in follicle-stimulating hormone and estradiol, over and above the effects of age. A major contributor to sleep complaints in the context of the menopausal transition is HFs, and many, although not all, HFs are linked with polysomnographic-defined awakenings, with HF-associated wake time contributing significantly to overall wakefulness after sleep onset. Some sleep complaints may be comorbid with depressive disorders or attributed to sleep-related breathing or movement disorders, which increase in prevalence especially after menopause, and for some women, menopause, age, and environmental/behavioral factors may interact to disrupt sleep. Considering the unique and multifactorial basis for sleep difficulties in women transitioning menopause, we describe clinical assessment approaches and management options, including combination treatments, ranging from cognitive behavioral therapy for insomnia to hormonal and nonhormonal pharmacological options. Emerging studies suggest that the impact of severe insomnia symptoms could extend beyond immediate health care usage and quality of life issues to long-term mental and physical health, if left untreated in midlife women. Appropriate treatment, therefore, has immediate benefit as well as advantages for maintaining optimal health in the postmenopausal years.

Sex differences in age-related changes in the sleep-wake cycle

Age-related changes in sleep and circadian regulation occur as early as the middle years of life. Research also suggests that sleep and circadian rhythms are regulated differently between women and men. However, does sleep and circadian rhythms regulation age similarly in men and women? In this review, we present the mechanisms underlying age-related differences in sleep and the current state of knowledge on how they interact with sex. We also address how testosterone, estrogens, and progesterone fluctuations across adulthood interact with sleep and circadian regulation. Finally, we will propose research avenues to unravel the mechanisms underlying sex differences in age-related effects on sleep.

Longitudinal Study of Insomnia Symptoms Among Women During Perimenopause

OBJECTIVE

To describe the prevalence of insomnia symptoms among women during perimenopause and to examine differences in self-reported insomnia symptoms at different stages of perimenopause over 10 years.

DESIGN

Secondary analysis of self-reported sleep symptoms and clinical variables using 10 years of publicly available data from the Study of Women Across the Nation (SWAN).

SETTING

The data set of women's insomnia symptoms was obtained from publicly available data from the SWAN. The parent study settings included Detroit, Michigan; Northern New Jersey; Los Angeles, California; Boston, Massachusetts; Chicago, Illinois; and Pittsburgh, Pennsylvania.

PARTICIPANTS

Multiethnic midlife women with a mean age of 46 years (N = 3,302) categorized as pre- and perimenopausal at baseline.

METHODS

Dependent variables included self-reported insomnia symptoms: difficulty falling asleep (sleep latency), wake after sleep onset, early morning awakenings, and sleep quality. Descriptive analysis was completed for each 1-year study interval. Repeated measures logistic regression was used to identify whether insomnia symptoms changed over time by stage of perimenopause.

RESULTS

Insomnia symptoms were present in 31% to 42% of perimenopausal women at any 1-year study interval. Insomnia symptoms were more prevalent in the late stage of perimenopause than the early stage (p < .001). The odds of having any insomnia symptoms were 1.3 times greater for women in the late stage of perimenopause than in the early stage (95% confidence interval [1.2, 1.5], p < .001).

CONCLUSION

Insomnia symptoms are prevalent in women transitioning to menopause, and stage of perimenopause may heighten the risk to develop symptoms of insomnia disorder, which is associated with negative cardiometabolic outcomes.

Effects of programmed exercise on depressive symptoms in midlife and older women: A meta-analysis of randomized controlled trials

OBJECTIVE

To perform a systematic review and meta-analysis to clarify the effect of programmed exercise on depressive symptoms (DSs) in midlife and older women.

METHODS

We carried out a structured search of PubMed-Medline, Web of Science, Scopus, Embase, Cochrane Library and Scielo, from database inception through June 29, 2017, without language restriction. The search included the following terms: "depression", "depressive symptoms", "exercise", "physical activity", "menopause", and "randomized controlled trial" (RCTs) in midlife and older women. The US, UK and Australian Clinical Trials databases were also searched. We assessed randomized controlled trials (RCTs) that compared the effect of exercise for at least 6 weeks versus no intervention on DSs as the outcome (as defined by trial authors). Exercise was classified according to duration as "mid-term exercise intervention" (MTEI; lasting for 12 weeks to 4 months), and "long-term exercise intervention" (LTEI; lasting for 6-12 months). Mean changes (±standard deviations) in DSs, as assessed with different questionnaires, were extracted to calculate Hedges' g and then used as the effect size for meta-analysis. Standardized mean differences (SMDs) of DSs after intervention were pooled using a random-effects model.

RESULTS

Eleven publications were included for analysis related to 1943 midlife and older women (age range 44-55 years minimum to 65.5±4.0 maximum), none of whom was using a hormone therapy. Seven MTEIs were associated with a significant reduction in DSs (SMD=-0.44; 95% CI -0.69, -0.18; p=0.0008) compared with controls. The reduction in DSs was also significant in six LTEIs (SMD=- 0.29; 95% CI -0.49; -0.09; p=0.005). Heterogeneity of effects among studies was moderate to high. Less perceived stress and insomnia (after exercise) were also found as secondary outcomes.

CONCLUSION

Exercise of low to moderate intensity reduces depressive symptoms in midlife and older women.

Sleep disorder, an independent risk associated with arterial stiffness in menopause

As women age and go through menopause, they suffer a higher incidence of sleep disorder, cardiovascular morbidity and mortality. In addition, evidences suggested that sleep disorder was an important pathological indicator for coronary heart disease. However, the relationship between different menopausal status, sleep disorder and cardiovascular diseases was unclear. Thus, we aim to assess the association between sleep disorder with arterial stiffness in females of 40–60 years free of cardiovascular diseases through self-administered Pittsburgh Sleep Quality Index (PSQI) and brachial-ankle pulse wave velocity (baPWV). Logistic regression revealed that sleep disorder (PSQI score ≥ 8) was an independent indicator for higher risk of elevated arterial stiffness (baPWV ≥ 1465.5 cm/s, upper tertile) beyond other established cardiovascular confounders in peri-postmenopause (OR 2.83, 95% confidence interval (CI) 2.00–4.00, p < 0.001), but not in premenopause (OR 1.67, 95% CI 0.71–3.90, p = 0.223). Collectively, it clearly indicates that sleep disorder in menopausal women is of prominent value to predict arterial stiffness.

Effect of exercise on sleep quality and insomnia in middle-aged women: A systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

We assessed the effects of programmed exercise (PE) on sleep quality and insomnia in middle-aged women (MAW).

METHODS

Searches were conducted in five databases from inception through December 15, 2016 for randomized controlled trials (RCTs) evaluating the effects of PE versus a non-exercising control condition on sleep quality, sleep disturbance and/or insomnia in MAW. Interventions had to last at least 8 weeks. Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI) and insomnia with the Insomnia Severity Index (ISI). Random effects models were used for meta-analyses. The effects on outcomes were expressed as mean differences (MDs) and their 95% confidence intervals (CI).

RESULTS

Five publications reported data from four RCTs on PE effects during 12-16 weeks on sleep quality (n=4 studies reporting PSQI results) and/or insomnia (n=3 studies reporting ISI results), including 660 MAW. Low-moderate levels of exercise significantly lowered the PSQI score (MD=-1.34; 95% CI -2.67, 0.00; p=0.05) compared with controls. In a subgroup analysis, moderate PE (aerobic exercise) had a positive effect on sleep quality (PSQI score MD=-1.85; 95% CI -3.62, -0.07; p=0.04), while low levels of physical activity (yoga) did not have a significant effect (MD-0.46, 95% CI -1.79, 0.88, p=0.50). In three studies (two studies of yoga, one study of aerobic exercise), there was a non-significant reduction in the severity of insomnia measured with the ISI score (MD -1.44, 95% CI -3.28, 0. 44, p=0.13) compared with controls. Heterogeneity of effects among studies was moderate to high.

CONCLUSION

In middle-aged women, programmed exercise improved sleep quality but had no significant effect on the severity of insomnia.

There are validated scales in multiple languages and considered appropriate for studying sleep disorders.

Sleep and menopause: a narrative review

OBJECTIVE

Our overall aim-through a narrative review-is to critically profile key extant evidence of menopause-related sleep, mostly from studies published in the last decade.

METHODS

We searched the database PubMed using selected Medical Subject Headings for sleep and menopause (n = 588 articles). Using similar headings, we also searched the Cochrane Library (n = 1), Embase (n = 449), Cumulative Index to Nursing and Allied Health Literature (n = 163), Web of Science (n = 506), and PsycINFO (n = 58). Articles deemed most related to the purpose were reviewed.

RESULTS

Results were articulated with interpretive comments according to evidence of sleep quality (self-reported) and sleep patterns (polysomnography and actigraphy) impact as related to reproductive aging and in the context of vasomotor symptoms (VMS; self-reported), vasomotor activity (VMA) events (recorded skin conductance), depressed mood, and ovarian hormones.

CONCLUSIONS

Predominantly, the menopausal transition conveys poor sleep beyond anticipated age effects. Perceptions of sleep are not necessarily translatable from detectable physical sleep changes and are probably affected by an emotional overlay on symptoms reporting. Sleep quality and pattern changes are mostly manifest in wakefulness indicators, but sleep pattern changes are not striking. Likely contributing are VMS of sufficient frequency/severity and bothersomeness, probably with a sweating component. VMA events influence physical sleep fragmentation but not necessarily extensive sleep loss or sleep architecture changes. Lack of robust connections between perceived and recorded sleep (and VMA) could be influenced by inadequate detection. There is a need for studies of women in well-defined menopausal transition stages who have no sleep problems, accounting for sleep-related disorders, mood, and other symptoms, with attention to VMS dimensions, distribution of VMS during night and day, and advanced measurement of symptoms and physiologic manifestations.

Examining the relationship between subjective sleep disturbance and menopause: a systematic review and meta-analysis

OBJECTIVE

The purpose of this study was to conduct a systematic review and meta-analysis of the relationship between menopausal stages and sleep disturbance reported using subjective methods. Secondary aims included examining the influence of culture/ethnicity on the relationship between menopausal stages and sleep disturbance.

METHODS

Multiple electronic databases were searched from the first available year to November 2013, and a manual search of the reference lists of review articles identified was also conducted. Twenty-four studies with a total of 63,542 midlife women were identified, coded, and analyzed.

RESULTS

The crude and adjusted odds of experiencing sleep disturbance were small but statistically significant for perimenopausal and postmenopausal women, using premenopause as the reference group. The ethnicity of the samples influenced effect sizes; Asian and white women both experienced an increased rate of sleep disturbance at the perimenopausal and postmenopausal stages compared with the premenopausal stage, whereas Hispanic women experienced no change in sleep disturbance across the menopausal transition.

CONCLUSIONS

The prevalence of sleep disturbance is higher in perimenopausal, postmenopausal, and surgical menopausal women than in premenopausal women. There is an independent relationship between menopausal stages and sleep disturbance beyond the effects of aging and other confounders, although the magnitude of the relationship is small. Culture, ethnicity, or both might affect the levels of sleep disturbance at various menopausal stages.

Treatment of Insomnia, Insomnia Symptoms, and Obstructive Sleep Apnea During and After Menopause: Therapeutic Approaches

Understanding sleep complaints among menopausal women is an emerging area of clinical and research interest. Several recent reviews have focused on mechanisms of menopausal insomnia and symptoms. In this review, we present a discussion on the most relevant and recent publications on the treatment of sleep disorders for menopausal women, with a focus on menopause-related insomnia, insomnia symptoms, and obstructive sleep apnea. We discuss both nonpharmacological and pharmacological treatments, including cognitive-behavioral therapy for insomnia (CBT-I), complementary and alternative medicine, hormone replacement therapy, sedative hypnotics, antidepressants, and continuous positive airway pressure. In addition, we briefly discuss methods and considerations of assessment of sleep disorders in menopausal women.

Among a sample of Iranian premenopausal and menopausal women differences in mood, sleep and health quality are small

BACKGROUND

Anecdotal evidence suggests that mood, sleep, and health quality change in women from premenopausal to menopausal period; however, data supporting these assumptions from non-Western countries are scarce. The aim of the present study was therefore to assess premenopausal and menopausal Iranian women with regard to mood, sleep, and general health.

METHODS

One hundred and twenty Iranian women took part in the study. Sixty were in a premenopausal state (mean age (M): = 46.9 years) and 60 in a menopausal state (M = 53.8 years). They completed a series of self-rating questionnaires related to sleep, mood, and health quality.

RESULTS

Compared to premenopausal women, menopausal women reported more difficulties such as falling asleep, and less general physical activities and vitality. No statistically significant differences were found for sleep quality, sleep schedules, difficulties in social life, general mood state, or general physical and mental health. Menopausal women reported to be more irritable, and to have more energy.

CONCLUSIONS

Data suggest that among a sample of Iranian premenopausal and menopausal women, differences in mood, sleep, and general health are small. Data, therefore, do not support "beliefs" and hearsay that mood, sleep, and general health do decrease from premenopausal to menopausal state.

Assessment of sleep quality and correlates in a large cohort of Colombian women around menopause

OBJECTIVE

The aim of this study was to determine the relationship between self-reported sleep quality, menopausal symptom intensity, and correlates (including ethnicity) among middle-aged women.

METHODS

The present cross-sectional study involved 1,078 Colombian women aged 40 to 59 years who completed the Pittsburgh Sleep Quality Index (PSQI), the Menopause Rating Scale (MRS), and a general questionnaire exploring sociodemographic data.

RESULTS

The median [interquartile range] age of the whole sample was 49.0 [9.0] years. Among the participants, 45.4% were postmenopausal, 57.2% had increased body mass index values, 13.9% were black, 20.7% had hypertension, 74.1% had a stable partner, and 3.8% used hormone therapy. The prevalence of poor sleep quality was 57.1% (PSQI global score ≥5). Significant correlations between PSQI global scores and MRS total and subscale scores were found. Multiple linear regression analysis found that higher PSQI scores (poorer quality of sleep) correlated with higher MRS psychological and somatic subscale scores (more severe symptoms), smoking habit, and hypertension. Menopause status and black ethnicity were excluded from the final regression model.

CONCLUSIONS

Despite study limitations, poor sleep quality is highly prevalent in this large middle-aged Colombian female sample and is related to menopausal symptom severity, tobacco use, and presence of hypertension.

Sleep disturbance and correlates in menopausal women in Shanghai

OBJECTIVE

The aim of this study was to investigate the sleep disturbance and its correlates in Chinese middle-aged women.

METHODS

A total of 2046 Chinese women 40-60 years of age were recruited in this cross-sectional descriptive study. The subjects were surveyed using the Pittsburgh Sleep Quality Index (PSQI), the modified Kupperman Index (KI), and a general questionnaire to obtain sociodemographic data. Data were analyzed using SPSS 20.0 software.

RESULTS

In this study, the mean (standard deviation) age of the participants was 51.69 (6.54) years and the mean PSQI score was 6.88 (3.20). The prevalence of sleep disturbance was 33.2% (a PSQI global score ≥8). The prevalence of sleep disturbance was higher in women with a menopausal status (from 34.8% in premenopausal women to 40.9% in postmenopausal women, P < .001) and in women with an increased age (from 21.7% in women 40-44 years of age to 41.8% in women 55-60 years of age, P < .001). Vasomotor symptoms (classical menopausal symptoms, VMS) were associated with sleep disturbance. An increase in the severity of menopausal symptoms (higher total KI scores) was observed in women who experienced sleep disturbance. A logistic regression analysis revealed that menopausal status, vasomotor symptoms, modified KI scores, a history of disease, and older age (≥ 50 years) were significant risk factors for sleep disturbance.

CONCLUSIONS

Sleep disturbance was highly prevalent in this large sample of middle-aged Chinese women. Therefore, clinicians should pay more attention to sleep problems in middle-aged Chinese women and measures should be taken to improve the quality of sleep in these women.

The pros and cons of plant estrogens for menopause

Concerns pertaining to the risk of estrogen exposure through HT have prompted an increase in the use of natural alternatives. Phytoestrogens may provide postmenopausal women with a practical alternative and many women have already begun to utilize phytoestrogen supplements. However, research regarding the efficacy of phytoestrogens as a hormone therapy alternative has been previously pessimistic or questionable at best. This review scrutinizes the most current research regarding the efficacy of three types of phytoestrogens, isoflavones, lignans and coumestans, and their specific effect on the reduction of climacteric symptoms, specifically vasomotor symptoms, vaginal atrophy, insomnia and osteoporosis. A discussion of the research pertaining to the relative safety of each phytoestrogen in terms of breast and endometrial health is also included. Overall, current research demonstrates that phytoestrogens are effective in reducing the intensity of hot flushes, and some phytoestrogen combinations result in a decreased frequency. Certain phytoestrogens have also been shown to decrease vaginal atrophy, improve sleep and cognition, and positively affect bone health. Even though initial research was generally unconvincing, the more recent evidence reviewed here is rather positive. In terms of safety and reports of adverse reactions, trials have not shown an increase in breast cancer risk or increase in endometrial hyperplasia following phytoestrogen use, but trials explicitly designed to find neoplasia have not been reported. Moreover, unlike hormone therapy, lignans may not increase clotting risk in postmenopausal women, thus supplements may serve as a treatment option for patients who have contraindications to hormone therapy. Phytoestrogens may provide a safe and partially effective alternative to HT. However, because research regarding phytoestrogens is relatively new, pharmaco-vigilence is still required, as these products are not yet FDA-approved. This article is part of a Special Issue entitled 'Phytoestrogens'.

Influence of sleep disturbances on quality of life of Iranian menopausal women

Background. Subjective sleep disturbances increase during menopause. Some problems commonly encountered during menopause, such as hot flushes and sweating at night, can cause women to have difficulty in sleeping. These complaints can influence quality of life of menopausal women. Methods. This cross-sectional study was performed on menopausal women attending health centers in Qazvin for periodic assessments. We measured excessive daytime sleepiness by Epworth sleepiness scale (ESS), obstructive sleep apnea (OSA) by the Berlin questionnaire, and insomnia by the insomnia severity index (ISI). We evaluate quality of life by the Menopause specific quality of life questionnaire (MENQOL). Results. A total of 380 menopausal women entered the study. Mean age of participated women was 57.6 ± 6.02. Mean duration of menopause was 6.3 ± 4.6. The frequency of severe and moderate insomnia was 8.4% (32) and 11.8% (45). Severe daytime sleepiness (ESS ≥ 10) was present in 27.9% (80) of the participants. Multivariate analytic results show that insomnia and daytime sleepiness have independent negative impact on each domain and total score of MENQOL questionnaire. Conclusion. According to our findings, EDS and insomnia are frequent in menopausal women. Both EDS and insomnia have significant quality of life impairment.

Consistently high sports/exercise activity is associated with better sleep quality, continuity and depth in midlife women: the SWAN sleep study

STUDY OBJECTIVES

To examine relationships between different physical activity (PA) domains and sleep, and the influence of consistent PA on sleep, in midlife women.

DESIGN

Cross-sectional.

SETTING

Community-based.

PARTICIPANTS

339 women in the Study of Women's Health Across the Nation Sleep Study (52.1 ± 2.1 y).

INTERVENTIONS

None.

MEASUREMENTS AND RESULTS

Sleep was examined using questionnaires, diaries and in-home polysomnography (PSG). PA was assessed in three domains (Active Living, Household/Caregiving, Sports/Exercise) using the Kaiser Physical Activity Survey (KPAS) up to 4 times over 6 years preceding the sleep assessments. The association between recent PA and sleep was evaluated using KPAS scores immediately preceding the sleep assessments. The association between the historical PA pattern and sleep was examined by categorizing PA in each KPAS domain according to its pattern over the 6 years preceding sleep assessments (consistently low, inconsistent/consistently moderate, or consistently high). Greater recent Sports/Exercise activity was associated with better sleep quality (diary "restedness" [P < 0.01]), greater sleep continuity (diary sleep efficiency [SE; P = 0.02]) and depth (higher NREM delta electroencephalographic [EEG] power [P = 0.04], lower NREM beta EEG power [P < 0.05]), and lower odds of insomnia diagnosis (P < 0.05). Consistently high Sports/Exercise activity was also associated with better Pittsburgh Sleep Quality Index scores (P = 0.02) and higher PSG-assessed SE (P < 0.01). Few associations between sleep and Active Living or Household/Caregiving activity (either recent or historical pattern) were noted.

CONCLUSION

Consistently high levels of recreational physical activity, but not lifestyle- or household-related activity, are associated with better sleep in midlife women. Increasing recreational physical activity early in midlife may protect against sleep disturbance in this population.

Assessment of insomnia and related risk factors in postmenopausal women screened for the metabolic syndrome

BACKGROUND

Sleep disturbances are common during female mid-life. Nevertheless, there is limited available information linking sleep characteristics to the menopause and the metabolic syndrome (METS).

OBJECTIVE

To assess insomnia prevalence and related risk factors in postmenopausal women screened for the METS.

METHODS

In this cross sectional study 204 natural postmenopausal women participating in a METS screening program filled out the Athens insomnia scale (AIS), the hospital anxiety and depression scale (HADS) and a general socio-demographic questionnaire. Criteria of the Adult Treatment Panel III (ATP-III) were used to define the METS.

RESULTS

Median age of the whole sample was 56 years. A 50.5% of women had the METS, 57.4% hot flushes, 58.3% were abdominally obese, 51.5% hypertension, 25.0% hyperglycemia, 15.7% depressed mood and 29.9% anxiety. A 33.8% presented insomnia according to the AIS (scores 6 or more). The AIS displayed a high internal consistency as computed Cronbach's alpha was determined to be 0.86. Multiple linear regression analysis determined that male premature ejaculation, female psychotropic drug use, hot flush intensity, mood morbidity (higher total HADS scores) and higher parity positively and significantly correlated to higher AIS scores (more insomnia).

CONCLUSION

In this postmenopausal sample insomnia was not related to the METS or its components yet to other psycho-somatic female and partner issues.

Pomegranate seed oil in women with menopausal symptoms: a prospective randomized, placebo-controlled, double-blinded trial

OBJECTIVE

The aim of this study was to investigate the potential effects of pomegranate seed oil (PGS) on menopausal symptoms.

METHODS

The prospective randomized, placebo-controlled, double-blinded trial was completed by 81 postmenopausal women, who received two daily doses of either 30 mg PGS containing 127 μg of steroidal phytoestrogens per dose or a placebo for 12 weeks. The participants reported their number of hot flashes and completed the Menopause Rating Scale II at baseline and at weeks 4, 8, 12, and 24. At baseline and after 12 weeks, hormonal status was determined.

RESULTS

After 12 weeks of treatment, PGS reduced the number of hot flashes per day by 4.3 (38.7%), whereas placebo reduced it by 2.5 (25.6%). Both groups were significant compared with baseline, but the treated group was not significant compared with the placebo group (P = 0.17). After 24 weeks, the treated group showed a mean of 7.1 (interquartile range, 4.0) hot flashes per day compared with the placebo group with a mean of 8.8 (interquartile range, 5.0; P = 0.02). Although the overall sum score of the Menopause Rating Scale II parameters at week 12 decreased in the treated group from 16.0 to 9.0 at week 12 and in the placebo group from 18.0 to 14.5 (P = 0.08), the sum score of the vegetative somatic symptoms subgroup decreased strongly versus placebo (P < 0.03), attributable mainly to an improvement in sleeping disorders. PGS did not affect the hormone status, and no adverse effects were reported.

CONCLUSIONS

In postmenopausal women, PGS does not significantly reduce hot flashes within a 12-week observation period, but further studies are needed to investigate the long-term effect.

A multinational study of sleep disorders during female mid-life

BACKGROUND

Although sleep disturbances are common during female mid-life, few studies have described in detail the prevalence of this problem and related risk factors.

OBJECTIVE

To determine the prevalence of sleep disturbances in mid-aged women using validated tools. Assessment of determinants capable of influencing the prevalence of insomnia and poor sleep quality was also performed.

METHODS

A total of 6079 women aged 40-59 of 11 Latin American countries were invited to fill out the Athens Insomnia Scale (AIS), the Pittsburgh Sleep Quality Index (PSQI), the Goldberg Anxiety and Depression Scale, the Menopause Rating Scale (MRS), the Brief Scale of Abnormal Drinking and a general socio-demographic questionnaire.

RESULTS

Overall, 56.6% of surveyed women suffered of either insomnia, poor sleep quality, or both. Specifically, 43.6% and 46.2% presented insomnia and poor sleep quality in accordance to the AIS and the PSQI respectively. The prevalence of insomnia increased with female age (from 39.7% in those aged 40-44 to 45.2% in those aged 55-59, p<0.0001) and menopausal stage (from 39.5% in premenopausal aged 40-44 to 46.3% in late postmenopausal ones, p<0.0001). "Awakening during the night" (AIS: Item 2) was the most highly rated of all items and contributing in a higher degree (mean 16%) to the total score of the scale in all menopausal phases. Sleep quality also worsened with age and menopausal status, impairment particularly affecting sleep efficiency and latency and the increased use of hypnotics. Vasomotor symptoms (VMS), depressive mood and anxiety were associated to sleep disturbances. Women presenting sleep disturbances displayed a 2-fold increase in the severity of menopausal symptoms (higher total MRS scores) which was translated into a 6-8 times higher risk of impaired quality of life. Logistic regression analysis determined that female age, the presence of chronic disease, troublesome drinking, anxiety, depression, VMS, drug use (hypnotics and hormone therapy) were significant risk factors related to the presence of sleep disturbances. Higher educational level related to less insomnia and better sleep quality.

CONCLUSION

Insomnia and poor sleep quality were highly prevalent in this mid-aged female sample in which the influence of age and the menopause was only modest and rather linked to menopausal symptoms already occurring since the premenopause.

Factors related to insomnia and sleepiness in the late third trimester of pregnancy

OBJECTIVE

To assess the presence of insomnia and sleepiness and related factors in the late third trimester of pregnancy.

METHODS

A total of 370 singleton gravids completed a general questionnaire containing personal data, the Insomnia Severity Index (ISI) and the Epworth Sleepiness Scale (ESS). In addition, maternal anthropometry was recorded upon survey.

RESULTS

Median [interquartile range] maternal age and gestational age upon survey was of 31 [7.0] years and 39 [1.8] weeks, respectively. A 73.5% of women displayed some degree of insomnia (Total ISI score 8-28) and 22.2% sleepiness (Total ESS score ≥10). Determined rho Spearman coefficients showed significant correlations between ISI scores and gestational age at survey and survey to birth interval (weeks) and between ESS scores and maternal weight and arm circumference at survey and neonatal birth weight. Multiple linear regression analysis found that smoking habit, higher blood pressure and shorter survey to birth interval (weeks) significantly predicted higher ISI scores, and hence a higher risk of insomnia. Employed status, increased arm circumference and neonatal weight predicted higher ESS scores (sleepiness).

CONCLUSION

Insomnia and sleepiness were prevalent in the late third trimester of pregnancy in which lifestyle factors and maternal and neonatal body composition were significant predictors.
