Study Objectives: The neuropeptide orexin promotes wakefulness, modulates thermoregulation, increases after menopause, and is normalized in women receiving estrogen therapy, suggesting a role for orexin antagonism as a treatment for the vasomotor symptom (VMS)-associated insomnia disorder. We tested the efficacy of the dual orexin receptor antagonist suvorexant for chronic insomnia related to nighttime VMS., Methods: In a double-blind, placebo-controlled trial, 56 women with chronic insomnia associated with nighttime VMS, Insomnia Severity Index (ISI) scores ≥15, and >30 min of diary-rated wake after sleep-onset (WASO) were randomized to receive oral suvorexant 10-20 mg (n = 27) or placebo (n = 29) nightly for 4 weeks. Analysis of within-person change in ISI was adjusted for baseline ISI and race., Results: Mean baseline ISI scores were 18.1 (95% CI, 16.8 to 19.4) and 18.3 (95% CI, 17.2 to 19.5) in the suvorexant and placebo groups, respectively (p = .81). The average 4-week ISI within-person decrease from baseline was greater on suvorexant (-8.1 [95% CI, -10.2 to -6.0]) compared to placebo (-5.6 [95% CI, -7.4 to -3.9], p = .04). Compared to placebo, nighttime diary-rated VMS frequency was significantly reduced with suvorexant (p < .01). While diary-rated WASO and total sleep time trended toward improvement on suvorexant, findings were not significant after adjustment for multiple comparisons. Daytime VMS and other sleep-related outcomes did not differ between groups. Suvorexant was well tolerated., Conclusion: These results suggest that suvorexant is likely a well-tolerated and efficacious treatment for VMS-associated insomnia disorder and reduces nighttime VMS. Antagonism of orexin receptors could provide a novel therapeutic option for midlife women with VMS-associated chronic insomnia., Clinical Trial Information: Efficacy of Suvorexant in the Treatment of Hot Flash-associated Insomnia, https://clinicaltrials.gov/ct2/show/NCT03034018, ClinicalTrials.gov Identifier: NCT03034018., (© The Author(s) 2022.

Purpose: Younger women are at risk for depression and related symptoms following breast cancer. The Pathways to Wellness study, a randomized, multi-institution, three-arm trial, tested the efficacy of two behavioral interventions for younger breast cancer survivors with elevated depressive symptoms: mindful awareness practices (MAPs) and survivorship education (SE) (Clincaltrials.gov identifier: NCT03025139)., Methods: Women diagnosed with breast cancer at or before 50 years of age who had completed treatment and had elevated depressive symptoms were randomly assigned to 6 weeks of MAPs, SE, or wait-list control (WLC). Assessments were conducted preintervention and postintervention and at 3-month and 6-month postintervention follow-ups. Analyses compared each intervention to WLC using linear mixed models. The primary outcome was change in depressive symptoms from preintervention to postintervention on the Center for Epidemiologic Studies-Depression Scale; secondary outcomes included change in fatigue, insomnia, and vasomotor symptoms., Results: Two hundred forty-seven women (median age = 46 years) were randomly assigned to MAPs (n = 85), SE (n = 81), or WLC (n = 81). MAPs and SE led to significant decreases in depressive symptoms from preintervention to postintervention relative to WLC (mean change relative to WLC [95% CI]: MAPs, -4.7 [-7.5 to -1.9]; SE, -4.0 [-6.9 to -1.1]), which persisted at 6-month follow-up for MAPs (mean change relative to WLC [95% CI]: MAPs, -3.7 [-6.6 to -0.8]; SE, -2.8 [-5.9 to 0.2]). MAPs, but not SE, also had beneficial effects on fatigue, insomnia, and vasomotor symptoms that persisted at 6-month follow-up ( P < .05)., Conclusion: Mindfulness meditation and SE reduced depressive symptoms in younger breast cancer survivors. These interventions can be widely disseminated over virtual platforms and have significant potential benefit for quality of life and overall survivorship in this vulnerable group., Competing Interests: Ann H.

Objective: Investigate temporal patterns of sleep maintenance problems in women who became surgically menopausal (hysterectomy with bilateral oophorectomy) before their final menstrual period and examine whether presurgery trajectories of sleep maintenance problems are related to problems staying asleep postsurgery., Methods: Longitudinal analysis of sleep self-reports collected every 1 to 2 years from 1996 to 2013 from 176 surgically menopausal women in the Study of Women's Health Across the Nation, a seven-site community-based, multiethnic/multiracial, cohort study. Median follow-up was 15.3 years (4.2 years presurgery, 10.2 years postsurgery). Group-based trajectory modeling was used to identify patterns of problems staying asleep, and the presurgery trajectories were used to predict similar postsurgery sleep problems., Results: Four trajectory patterns of sleep maintenance problems were identified: low (33.5% of women), moderate (33.0%), increasing during presurgery (19.9%), and high (13.6%). One-fifth of women reported a presurgery increase in these problems. Postsurgically, problems staying asleep remained associated with similar levels of presurgical problems, even after adjusting for postsurgical early morning awakening, frequent vasomotor symptoms, and bodily pain score (βlow = -1.716, βmoderate = -1.144, βincreasing = -0.957, βhigh = -1.021; all P values <0.01)., Conclusions: Sleep maintenance problems were relatively stable across time postsurgery. These data are remarkably consistent with our trajectory results across the natural menopause, suggesting that presurgical assessment of sleep concerns could help guide women's expectations postsurgically. Although reassuring that sleep complaints do not worsen postsurgically for most surgically menopausal women, referral to a sleep specialist should be considered if sleep symptoms persist or worsen after surgery.

Objective: Women's sleep at menopause is widely reported to be problematic. The Insomnia Severity Index (ISI) is a commonly used tool for quantifying sleep problems in clinical and research settings, but psychometric properties in postmenopausal women have not been reported. Our study aim was to examine the factor structure of the ISI in a large and diverse sample of midlife women with hot flashes., Methods: Baseline data were from 899 women enrolled in one of the three clinical trials using similar entry criteria conducted by the Menopause Strategies Finding Lasting Answers to Symptoms and Health research network. We conducted confirmatory factor analyses for the total sample and within strata defined by race/ethnicity (black and white women)., Results: The ISI had two factors in the total sample. The two-factor structure was consistent across black and white women, with the exception of one item "difficulty falling asleep.", Conclusions: The ISI in midlife women with hot flashes is composed of two factors that capture dimensions of the insomnia severity and daytime impact. The instrument is a psychometrically sound scale appropriate for use in research and clinical practice to capture the severity and daytime impact of insomnia symptoms in diverse samples of midlife women with hot flashes. An abbreviated screening of two items could be considered to determine if further evaluation is needed of sleep complaints.

Objectives: Given the neurocognitive hyperarousal observed in patients with insomnia disorder and associations of nocturnal hot flashes with cardiovascular disease risk, we examined whether women with hot flash-associated insomnia disorder demonstrate exaggerated cardiovascular responsivity to acute stressors, and also a profile of psychological hyperarousal., Methods: Peri and postmenopausal women with and without hot flash-associated insomnia disorder underwent assessments of cardiovascular autonomic responsivity to acute stress paradigms and psychological hyperarousal. Hemodynamic responses (heart rate, blood pressure) to nociceptive, social-evaluative, and cognitive stress paradigms were measured in the morning. Psychological hyperarousal was evaluated using questionnaires assessing daytime and presleep hyperarousal, anxiety, and sleep-related cognitions., Results: Women (25 with and 15 without hot flash-associated insomnia) aged 53.4 ± 4.8 years reported a range of insomnia symptoms. Resting-state hemodynamics were similar between groups. Heart rate and blood pressure responses to stress paradigms did not differ by group nor did they correlate with insomnia severity. Women with insomnia disorder had higher generalized anxiety disorder scores (mean 2.7 ± 3.0 vs 1.0 ± 1.4; P = 0.05) and sleep-related cognitions than those without insomnia (P ≤ 0.05). Insomnia symptom severity was moderately correlated with presleep and daytime hyperarousal, anxiety, and sleep-related cognition (all r ≥ 0.43)., Conclusions: Though hot flash-associated insomnia is characterized by psychological hyperarousal before sleep and during the daytime, it does not relate to cardiovascular responsiveness to acute stressors. Our findings do not support the hypothesis that altered cardiovascular control is a potential mechanism by which hot flash-associated insomnia confers higher cardiovascular disease risk.

Study Objectives: The Menopause Strategies: Finding Lasting Answers for Symptoms and Health network conducted three randomized clinical trials (RCTs) testing six interventions treating vasomotor symptoms (VMS), and also collected self-reported sleep outcomes. A fourth RCT assessed an intervention for insomnia symptoms among women with VMS. We describe these seven interventions' effects relative to control in women with comparably severe insomnia symptoms and VMS., Methods: We analyzed pooled individual-level data from 546 peri- and postmenopausal women with Insomnia Severity Index (ISI) ≥ 12, and ≥14 bothersome VMS/week across the four RCTs. Interventions included the following: escitalopram 10-20 mg/day; yoga; aerobic exercise; 1.8 g/day omega-3 fatty acids; oral 17-beta-estradiol 0.5-mg/day; venlafaxine XR 75-mg/day; and cognitive behavioral therapy for insomnia (CBT-I). Outcome measures were ISI and Pittsburgh Sleep Quality Index (PSQI) over 8-12 weeks of treatment., Results: CBT-I produced the greatest reduction in ISI from baseline relative to control at -5.2 points (95% CI -7.0 to -3.4). Effects on ISI were similar for exercise at -2.1 and venlafaxine at -2.3 points. Comparably small decreases in ISI were observed with escitalopram, yoga, and estradiol. The largest reduction in PSQI from baseline was with CBT-I at -2.7 points (-3.9 to -1.5), although PSQI decreases of 1.2 to 1.6 points were significantly better than control with escitalopram, exercise, yoga, estradiol, and venlafaxine. Omega-3 supplements did not improve insomnia symptoms., Conclusions: This study's findings support current recommendations for CBT-I as a first line treatment in healthy midlife women with insomnia symptoms and moderately bothersome VMS., (© Sleep Research Society 2017.

Study Objectives: While women report sleep interruption secondary to nighttime hot flashes, the sleep disrupting impact of nocturnal hot flashes (HF) is not well characterized. We utilized a model of induced HF to investigate the relationship of nighttime HF to sleep architecture and sleep-stage transitions., Methods: Twenty-eight healthy, premenopausal volunteers received the depot gonadotropin-releasing hormone agonist (GnRHa) leuprolide to rapidly induce menopause, manifesting with HF. Sleep disruption was measured on 2 polysomnograms conducted before and after 4-5 weeks on leuprolide, when HF had developed., Results: 165 HF episodes were recorded objectively during 48 sleep studies (mean 3.4 HF/night). After standardizing to sleep-stage time distribution, the majority of HF were recorded during wake (51.0%) and stage N1 (18.8%). Sixty-six percent of HF occurred within 5 minutes of an awakening, with 80% occurring just before or during the awakening. Objective HF were not associated with sleep disruption as measured by increased transitions to wake or N1, but self-reported nocturnal HF correlated with an increase from pre- to post-leuprolide in the rate of transitions to wake (p = 0.01), and to N1 (p = 0.008)., Conclusions: By isolating the effect of HF on sleep in women without the confound of age-related sleep changes associated with natural menopause, this experimental model shows that HF arise most commonly during N1 and wake, typically preceding or occurring simultaneously with wake episodes. Perception of HF, but not objective HF, is linked to increased sleep-stage transitions, suggesting that sleep disruption increases awareness of and memory for nighttime HF events., Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT01116401., (© 2016 American Academy of Sleep Medicine.)

Importance: Effective, practical, nonpharmacologic therapies are needed to treat menopause-related insomnia symptoms in primary and women's specialty care settings., Objective: To evaluate the efficacy of telephone-based cognitive behavioral therapy for insomnia (CBT-I) vs menopause education control (MEC)., Design, Setting, and Participants: A single-site, randomized clinical trial was conducted from September 1, 2013, to August 31, 2015, in western Washington State among 106 perimenopausal or postmenopausal women aged 40 to 65 years with moderate insomnia symptoms (Insomnia Severity Index [ISI] score, ≥12) and 2 or more daily hot flashes. Blinded assessments were conducted at baseline, 8, and 24 weeks postrandomization. An intent-to-treat analysis was conducted., Interventions: Six CBT-I or MEC telephone sessions in 8 weeks. Participants submitted weekly electronic sleep diaries and received group-specific written educational materials. The CBT-I sessions included sleep restriction, stimulus control, sleep hygiene education, cognitive restructuring, and behavioral homework; MEC sessions provided information about menopause and women's health., Main Outcomes and Measures: Primary outcome was scores on the ISI (score range, 0-28; scores ≥15 indicate moderate to severe insomnia). Secondary outcome was scores on the Pittsburgh Sleep Quality Index (score range, 0-21; higher scores indicate worse sleep quality). Additional outcomes included sleep and hot flash diary variables and hot flash interference., Results: At 8 weeks, ISI scores had decreased 9.9 points among 53 women receiving CBT-I (mean [SD] age, 55.0 [3.5] years) and 4.7 points among 53 women receiving MEC (age, 54.7 [4.7] years), a mean between-group difference of 5.2 points (95% CI, -6.1 to -3.3; P < .001). Pittsburgh Sleep Quality Index scores decreased 4.0 points in women receiving CBT-I and 1.4 points in women receiving MEC, a mean between-group difference of 2.7 points (95% CI, -3.9 to -1.5; P < .001). Significant group differences were sustained at 24 weeks. At 8 and 24 weeks, 33 of 47 women (70%) and 37 of 44 (84%) in the CBT-I group, respectively, had ISI scores in the no-insomnia range compared with 10 of 41 (24%) and 16 of 37 (43%) in the MEC group, respectively. The CBT-I group also had greater improvements in diary-reported sleep latency, wake time, and sleep efficiency. There were no between-group differences in frequency of daily hot flashes, but hot flash interference was significantly decreased at 8 weeks for the CBT-I group (-15.7; 95% CI, -20.4 to -11.0) compared with the MEC group (-7.1; 95% CI, -14.6 to 0.4) (P = .03), differences that were maintained at 24 weeks for the CBT-I group (-22.8; 95% CI, -28.6 to -16.9) and MEC group (-11.6; 95% CI, -19.4 to -3.8) (P = .003)., Conclusions and Relevance: Telephone-based CBT-I improved sleep in perimenopausal and postmenopausal women with insomnia and hot flashes. Results support further development and testing of centralized CBT-I programs for treating menopausal insomnia., Trial Registration: clinicaltrials.gov Identifier: NCT01936441.

Objective: Our objective was to identify symptom clusters using standardized measures completed by participants in the Menopausal Strategies: Finding Lasting Answers to Symptoms and Health clinical trial at baseline, including hot flash interference, and sleep, depressive, anxiety, and pain symptoms., Methods: Data from all women randomized to interventions and controls from Menopausal Strategies: Finding Lasting Answers to Symptoms and Health studies 1, 2, and 3 (N = 899) were included; 797 with complete data were used in the analyses. Scores from standardized measures obtained at baseline included the following: Hot Flash-Related Daily Interference Scale, Insomnia Severity Index, Pittsburgh Sleep Quality Index, Patient Health Questionnaire-9 measure of depressed mood, Generalized Anxiety Disorder, and Brief Pain Inventory PEG scores (pain intensity [P], interference with enjoyment of life [E], and interference with daily activity [G]). Latent class analysis was used to identify symptom clusters using standardized scale scores and their established cut points., Results: We identified five classes using the Bayesian Information Criterion and the Akaike Information Criterion. Women in classes 1 and 2 had high hot flash interference levels relative to the others, and class 1 (10.5% of total) included severe hot flash interference, severe sleep symptoms, and moderately severe pain symptoms (hot flash, sleep, pain). In class 2 (14.1%), severe hot flash interference was paired with the severe sleep symptoms, and moderate to severe depressed and anxious mood symptoms and pain (hot flash, sleep, mood, pain). In class 3 (39.6%), women reported moderately severe sleep symptoms with moderate hot flash interference, and low severity mood and pain symptoms (hot flash, sleep). Those in class 4 (7.0%) reported moderate hot flash interference with severe levels of anxiety and depressed mood symptoms, but low levels of other symptoms (hot flash, mood). Women in class 5 (28.7%) reported the lowest levels of all the five symptoms (low severity symptoms)., Conclusions: Women meeting hot flash frequency criteria for inclusion in clinical trials exhibited multiple co-occurring symptoms that clustered into identifiable groups according to symptom interference and severity. Variability of symptom profiles between the classes was evident, indicating that the classes were composed of differing symptom types and not simply differing severity levels. These symptom clusters may be useful phenotypes for differentiating treatment effects or evaluating associations with biomarkers or genes.

Study Objectives: Determine effects of low-dose estradiol and low-dose venlafaxine on self-reported sleep measures in menopausal women with hot flashes., Design: 3-arm double-blind randomized trial. Participants assigned in a 2:2:3 ratio to 17β estradiol 0.5 mg/day (n = 97), venlafaxine XR 75 mg/day (n = 96), or placebo (n = 146) for 8 weeks., Setting: Academic research centers., Participants: 339 community-dwelling perimenopausal and postmenopausal women with ≥2 bothersome hot flashes per day., Measurements and Results: Insomnia symptoms (Insomnia Severity Index [ISI]) and sleep quality (Pittsburgh Sleep Quality Index [PSQI]) at baseline, week 4 and 8; 325 women (96%) provided ISI data and 312 women (92%) provided PSQI data at baseline and follow-up. At baseline, mean (SD) hot flash frequency was 8.1/day (5.3), mean ISI was 11.1 (6.0), and mean PSQI was 7.5 (3.4). Mean (95% CI) change from baseline in ISI at week 8 was -4.1 points (-5.3 to -3.0) with estradiol, -5.0 points (-6.1 to -3.9) with venlafaxine, and -3.0 points (-3.8 to -2.3) with placebo (P overall treatment effect vs. placebo 0.09 for estradiol and 0.007 for venlafaxine). Mean (95% CI) change from baseline in PSQI at week 8 was -2.2 points (-2.8 to -1.6) with estradiol, -2.3 points (-2.9 to -1.6) with venlafaxine, and -1.2 points (-1.7 to -0.8) with placebo (P overall treatment effect vs. placebo 0.04 for estradiol and 0.06 for venlafaxine)., Conclusions: Among perimenopausal and postmenopausal women with hot flashes, both low dose oral estradiol and low-dose venlafaxine compared with placebo modestly reduced insomnia symptoms and improved subjective sleep quality., Clinical Trial Registration: NCT01418209 at www.clinicaltrials.gov., (© 2014 Associated Professional Sleep Societies, LLC.)

Objective: This study aims to determine the efficacy of yoga in alleviating vasomotor symptoms (VMS) frequency and bother., Methods: This study was a three-by-two factorial, randomized controlled trial. Eligible women were randomized to yoga (n = 107), exercise (n = 106), or usual activity (n = 142), and were simultaneously randomized to a double-blind comparison of ω-3 fatty acid (n = 177) or placebo (n = 178) capsules. Yoga intervention consisted of 12 weekly 90-minute yoga classes with daily home practice. Primary outcomes were VMS frequency and bother assessed by daily diaries at baseline, 6 weeks, and 12 weeks. Secondary outcomes included insomnia symptoms (Insomnia Severity Index) at baseline and 12 weeks., Results: Among 249 randomized women, 237 (95%) completed 12-week assessments. The mean baseline VMS frequency was 7.4 per day (95% CI, 6.6 to 8.1) in the yoga group and 8.0 per day (95% CI, 7.3 to 8.7) in the usual activity group. Intent-to-treat analyses included all participants with response data (n = 237). There was no difference between intervention groups in the change in VMS frequency from baseline to 6 and 12 weeks (mean difference [yoga--usual activity] from baseline at 6 wk, -0.3 [95% CI, -1.1 to 0.5]; mean difference [yoga--usual activity] from baseline at 12 wk, -0.3 [95% CI, -1.2 to 0.6]; P = 0.119 across both time points). Results were similar for VMS bother. At week 12, yoga was associated with an improvement in insomnia symptoms (mean difference [yoga - usual activity] in the change in Insomnia Severity Index, 1.3 [95% CI, -2.5 to -0.1]; P = 0.007)., Conclusions: Among healthy women, 12 weeks of yoga class plus home practice, compared with usual activity, do not improve VMS frequency or bother but reduce insomnia symptoms.

Objective: The impact of hot flashes on sleep is of great clinical interest, but results are inconsistent, especially when both hot flashes and sleep are measured objectively. Using objective and subjective measurements, we examined the impact of hot flashes on sleep by inducing hot flashes with a gonadotropin-releasing hormone agonist., Methods: The gonadotropin-releasing hormone agonist leuprolide was administered to 20 healthy premenopausal volunteers without hot flashes or sleep disturbances. Induced hot flashes were assessed objectively (skin conductance monitor) and subjectively (daily diary) during 1-month follow-up. Changes from baseline in objective sleep quality (actigraphy) and subjective sleep quality (Pittsburgh Sleep Quality Index) were compared between women who developed and women who did not develop objective hot flashes and, in parallel analyses, subjective hot flashes., Results: New-onset hot flashes were recorded in 14 (70%) women and reported by 14 (70%) women (80% concordance). Estradiol was universally suppressed. Objective sleep efficiency worsened in women with objective hot flashes and improved in women without objective hot flashes (median decrease, 2.6%; median increase, 4.2%; P = 0.005). Subjective sleep quality worsened more in those with subjective hot flashes than in those without subjective hot flashes (median increase in Pittsburgh Sleep Quality Index, 2.5 vs 1.0; P = 0.03). Objective hot flashes were not associated with subjective sleep quality, nor were subjective symptoms linked to objective sleep measures., Conclusions: This experimental model of induced hot flashes demonstrates a causal relationship between hot flashes and poor sleep quality. Objective hot flashes result in worse objective sleep efficiency, whereas subjective hot flashes worsen perceived sleep quality.

Objective: The aim of this study was to determine the effect of escitalopram on insomnia symptoms and subjective sleep quality in healthy perimenopausal and postmenopausal women with hot flashes., Methods: A randomized, blinded, multicenter, placebo-controlled parallel-group 8-week trial with 205 women (95 African American, 102 white, 8 other) was conducted between July 2009 and June 2010. The participants received escitalopram (10-20 mg/d) or placebo. Insomnia symptoms (Insomnia Severity Index [ISI]) and subjective sleep quality (Pittsburgh Sleep Quality Index [PSQI]) at weeks 4 and 8 were the prespecified secondary outcomes. A total of 199 women (97%) provided ISI data, and 194 (95%) women provided PSQI data at follow-up., Results: At baseline, mean hot flash frequency was 9.78 per day (SD, 5.60), mean ISI was 11.4 (SD, 6.3), and mean PSQI was 8.0 (SD, 3.7). Treatment with escitalopram reduced ISI at week 8 (mean difference, -2.00; 95% CI, -3.43 to -0.57; P < 0.001 overall treatment effect), with mean differences of -4.73 (95% CI, -5.72 to -3.75) in the escitalopram group and -2.73 (95% CI, -3.78 to -1.69) in the placebo group. The reduction in PSQI was greater in the escitalopram than in the placebo group at week 8 (mean difference, -1.31; 95% CI, -2.14 to -0.49; P < 0.001 overall treatment effect). Clinical improvement in insomnia symptoms and subjective sleep quality (≥50% decreases in ISI and PSQI from baseline) was observed more frequently in the escitalopram group than in the placebo group (ISI, 50.0% vs 35.4%, P = 0.04; PSQI, 29.6% vs 19.2%, P = 0.09)., Conclusions: Among healthy perimenopausal and postmenopausal women with hot flashes, escitalopram at 10 to 20 mg/day compared with placebo reduced insomnia symptoms and improved subjective sleep quality at 8 weeks of follow-up.

Sleep disturbances in midlife women are common and have been associated with the menopause transition itself, symptoms of hot flashes, anxiety and depressive disorders, aging, primary sleep disorders (i.e., obstructive sleep apnea, periodic limb movement disorder), comorbid medical conditions and medications, as well as with psychosocial and behavioral factors. Because there are several common sources of sleep problems in midlife women, the cause of an individual woman's sleep disturbance may be multifactorial. Effective behavioral and pharmacological therapies are available to treat sleep disturbances of different etiologies. This review provides an overview of different types of sleep disturbance occurring in midlife women and presents data supporting the use of hormone therapy, hypnotic agents, and behavioral strategies to treat sleep problems in this population. The review aims to equip clinicians evaluating menopause-age women with the knowledge and evaluation tools to diagnose, engage sleep experts where appropriate, and treat sleep disturbance in this population. Sleep disorders in midlife women should be treated because substantial improvements in quality of life and health outcomes are achievable., (© Thieme Medical Publishers.)

Objective: Menopause-associated insomnia is commonly associated with other symptoms (hot flashes, depression, anxiety). Given frequent symptom cooccurrence, therapies targeting sleep may provide an important approach to treatment during midlife., Study Design: Peri/postmenopausal women (40-65 years old) with sleep-onset and/or sleep-maintenance insomnia cooccurring with hot flashes and depressive and/or anxiety symptoms were randomized to eszopiclone 3 mg orally or placebo in a double-blinded, crossover 11 week trial. Changes in the Insomnia Severity Index (ISI) scale and secondary outcomes (diary-based sleep parameters, depression/anxiety, hot flashes, quality of life) were analyzed using repeated-measure linear models., Results: Of 59 women, 46 (78%) completed the study. Eszopiclone reduced ISI scores by 8.7 + or - 1.4 more points than placebo (P < .0001). Eszopiclone improved (P < .05) all sleep parameters, depressive symptoms, anxiety symptoms, quality of life, and nighttime but not daytime hot flashes., Conclusion: Eszopiclone treats insomnia and cooccurring menopause-related symptoms. Our results provide evidence that hypnotic therapies may improve multiple domains of well-being during midlife., (Copyright 2010 Mosby, Inc. All rights reserved.)

Objective: To evaluate eszopiclone 3 mg for treatment of insomnia in perimenopausal and early postmenopausal women, as well as the impact of insomnia treatment on mood, menopause-related symptoms, and quality of life., Methods: This was a double-blind, placebo-controlled study with 410 women (aged 40-60; perimenopausal or early postmenopausal) who reported insomnia defined as sleep latency of at least 45 minutes and total sleep time less than or equal to 6 hours per night for at least 3 nights per week over the previous month. Patients were randomly assigned to eszopiclone 3 mg or placebo nightly for 4 weeks. Sleep data were collected once a day. Physician global assessments of menopause, menopause-specific questionnaire, Greene Climacteric Scale, the Montgomery Asberg Depression Rating Scale, and the Sheehan Disability Scale were collected at baseline and end of treatment., Results: Patients receiving eszopiclone reported improvements in sleep induction, sleep maintenance, sleep duration, sleep quality, and next-day functioning relative to placebo (P<.05). Patients receiving eszopiclone reported fewer total awakenings and awakenings due to hot flushes (P<.05). Eszopiclone use led to greater improvement in Montgomery Asberg Depression Rating Scale scores (P<.05) and physician global assessments of menopause scores (P<.001); total Greene Climacteric Scale score and the vasomotor and psychological sub-scores (P<.05); vasomotor and physical domains of the menopause-specific questionnaire (P<.05); and family life/home domain of the Sheehan Disability Scale (P<.05)., Conclusion: In this study, eszopiclone provided significant improvements in sleep and positively impacted mood, quality of life, and menopause-related symptoms in perimenopausal and early postmenopausal women with insomnia., Clinical Trial Registration: ClinicalTrials.gov www.clinicaltrials.gov NCT00366093, Level of Evidence: I.
