The research was conducted as a randomized controlled study with the aim of determining the effect of yoga on menopause symptoms. Menopausal women between the ages of 40 and 60 years were included in the research. There were 31 menopausal women in each of 2 groups, making a total of 62. A Descriptive Characteristics Form and the Menopause Rating Scale (MRS) were used to collect data. In the research, the yoga group practiced yoga for 60 minutes twice a week for 10 weeks. In the final lesson of the 10 weeks of yoga training, the women were again given the MRS. No intervention was performed on the control group. The median score on the MRS of the women in the yoga group was 16 (11-21) in the pretest, and 5 (3-9) in the posttest (P < .05). The median score on the subscale of psychological complaints of the women in the yoga group was 6 (3-8) in the pretest, and 1 (1-2) in the posttest (P < .05). The median score on the subscale of urogenital complaints of the women in the yoga group was 3 (3-5) in the pretest, and 1 (0-2) in the posttest (P < .05). The median score on the subscale of somatic complaints of the women in the yoga group was 7 (4-10) in the pretest, and 1 (1-3) in the posttest (P < .05). It was concluded from the research that 60 minutes of yoga 2 days a week for 10 weeks may reduce the psychological, somatic, and urogenital symptoms experienced in menopause.

IMPORTANCE: Physical activity during menopause can be effective in reducing the physiological changes associated with reproductive aging that increase risks for noncommunicable diseases, yet many women do not meet the recommendations for physical activity. OBJECTIVE: This study aimed to synthesize factors influencing physical activity for women across menopausal transition phases using a socioecological approach. EVIDENCE REVIEW: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis was used to systematically search 10 databases between 2001 and 2021. A comprehensive search strategy was used to identify studies on physical activity of women in various stages of menopause. A socioecological model was used to categorize the reported barriers and enablers. FINDINGS: Twenty studies met the inclusion criteria. The findings highlight several intrapersonal barriers such as existing health complaints versus enablers such as awareness of the health benefits of physical activity during menopause. Ensuring women's safety, preventing injury, and enhancing exercise self-efficacy were important components of programs. Social support was also an important enabler of women's engagement in activities. CONCLUSIONS AND RELEVANCE: Several barriers and enablers were identified and can inform practitioners and future interventions to encourage physical activity among women in various stages of menopause. For instance, when encouraging physical activity during menopause, practitioners should consider other health complaints, safety, and injury prevention while discussing the benefits of physical activity related to managing menopausal symptoms. There was a lack of theoretically informed studies exploring the barriers and enablers to physical activity for women in various stages of menopause; thus, research designs may not have fully accounted for influences. Future research that combines socioecological and individual theories of behavior is needed to comprehensively understand the complexity of physical activity among women across the menopausal transition.

BACKGROUND: The association between reproductive lifespan and depression in older women is unclear. We conducted this analysis to explore whether a shorter reproductive lifespan is associated with higher odds of depression, while also considering the age at menarche and age at menopause. METHODS: This observational study used data from the National Health and Nutrition Examination Survey (NHANES), which was conducted between 2005 and 2018. Reproductive lifespan was defined as years from age at menarche to age at menopause. Depression was assessed using the Patient Health Questionnaire-9 (PHQ-9). Multivariable logistic regression models were used to explore the relationship between the association of reproductive life span, age at menarche and age at menopause with the incidence of depression. RESULTS: Totally, 2947 patients aged 60 and above were enrolled in the trial, with 241 individuals (8.18 %) diagnosed with depression. Higher odds of depression were found to be significantly correlated with a shorter reproductive lifespan [Odds Ratio (OR) = 0.95, 95 % Confidence interval (CI) = 0.92-0.98] or an earlier ager at menopause (OR = 0.95, 95 % CI = 0.92-0.99), according to the results of multivariable logistic regression analysis after full adjustment. Subgroup analysis and interaction tests indicated a similar association. LIMITATIONS: The cross-sectional study could not yield any conclusions regarding causality. CONCLUSION: In this large cross-sectional study, our result suggested that populations with a shorter reproductive lifespan or an earlier age at menopause were significantly more likely to have depressive symptoms in older U.S. women. Further large-scale prospective studies are warranted for a comprehensive analysis of the role of the reproductive lifespan and age at menopause in depression.

OBJECTIVE: The aim of this study was to determine the state of aging anxiety in middle-aged women. METHODS: The study was collected from women between the ages of 40 and 59 years by an online survey method. While collecting the data of the participants, the women's personal characteristics diagnostic form and the Aging Anxiety Scale for Middle-Aged Women were used. The data were analyzed with the SPSS 26 statistical software. RESULTS: The aging anxiety of the women was found to be moderate (53.05±16.26). A significant correlation was found between women's menopausal status, household income, education level, and total score of aging anxiety (p<0.05). CONCLUSION: In addition to working outside the home, women are also burdened with duties inside the home. To improve their quality of life, women need to share many of the tasks imposed on them with other family members. To reduce the anxiety experienced by women during the climacteric period, it is recommended to provide psychosocial support to women and consider this issue in health policies. Healthcare professionals, especially nurses, have important duties to reduce anxiety and stress, which constitute the basis of many chronic diseases. It is recommended that nurses, who are health ambassadors, direct women with anxiety to psychological support services through screenings they will conduct for women during this period.

Background and Purpose: Complaints about menopause vary between cultures, and the experience of menopause changes significantly in women living in different countries. Limited evidence is available regarding the menopausal experience among Asian women. This study aims to explore the menopausal transition experiences of Vietnamese women. Methods: A qualitative inquiry was undertaken using the grounded theory approach. Semi-structured interviews were conducted and analyzed following constructivist grounded theory methods. Results: In the early transition, women's lives underwent many challenges. They had physical manifestations of menopause and difficulty in their sexual life. Later, women identified that their psychosocial impacts were affected, leading to emotional changes and changes in perceptions of others about the menopausal transition. The study also showed that each woman had their own beliefs and religion. Finally, after experiencing physical and mental changes, women found methods for discomfort relief. These methods included seeking information, applying strategies to manage menopausal challenges and consequences, and maintaining balance. Implications for Practice: The diverse perspectives on women's menopausal transition can help nurses and other health care professionals to provide culturally appropriate care for women.

BACKGROUND: Natural menopause is defined as the permanent cessation of menstruation that occurs after 12 consecutive months of amenorrhea without any obvious pathological or physiological cause. The age of this phenomenon has been reported to be associated with several health outcomes. OBJECTIVES: This study aimed to estimate the Age at Natural Menopause (ANM) and to identify reproductive and demographic factors affecting ANM. METHODS: This cross-sectional, population-based study was conducted on 2517 post-menopausal women aged 40-70 years participating in the first phase of the PERSIAN cohort study of Kharameh, Iran, during 2014-2017. To more accurately detect the determinants of ANM, we applied multiple linear regression beside some machine learning algorithms including conditional tree, conditional forest, and random forest. Then, the fitness of these methods was compared using Mean Squared Error (MSE) and Pearson correlation coefficient. RESULTS: The mean±SD of ANM was 48.95±6.13. Both applied forests provided more accurate results and identified more predictors. However, according to the final comparison, the conditional forest was the most accurate method which recognized that more pregnancies, longer breastfeeding, Fars ethnicity, and urbanization have the greatest impact on later ANM. CONCLUSIONS: This study found a wide range of reproductive and demographic factors affecting ANM. Considering our findings in decision-making can reduce the complications related to this phenomenon and, consequently, improve the quality of life of post-menopausal women.

Midlife individuals assigned female at birth are at risk for problematic eating behavior, associated with negative health outcomes. Little is known about how menopausal symptoms may increase risk in this population. The current study aimed to understand how a comprehensive range of menopause symptoms were globally associated with problematic eating behaviors. A total of 281 cisgender women (176 post-menopause, 105 peri-menopause) from the United States aged 40 to 64 were recruited utilizing Prolific, an online survey platform. Participants answered questionnaires about menopause symptoms and problematic eating. Participants were selected using demographic and health information provided in a screener survey. Participants also completed the Eating Disorder Questionnaire (EDE-Q), Women's Health Questionnaire (WHQ), Patient Health Questionnaire-8 (PHQ-8), Generalized Anxiety Disorder-7 (GAD-7), and Pittsburgh Sleep Quality Index (PSQI). Using Structural Equation Modeling, menopause symptoms explained 16.7 percent of the variance in problematic eating. Higher frequency and severity of anxiety, depression, sleep concerns, cognitive complaints, pain, and vasomotor symptoms was associated with greater frequency and severity of problematic eating behaviors, ß = .40, p < .001. Invariance testing showed no significant differences between peri- and postmenopausal women. These findings support the association between menopause symptoms and problematic eating in Midlife cisgender women and highlight the need for continued investigation.

Background and Objectives: Hormonal changes physiologically occurring in menopausal women may increase the risk of developing metabolic and vasomotor disturbances, which contribute to increase the risk of developing other concomitant pathologies, such as metabolic syndrome (MetS). Materials and Methods: Retrospective data from 200 menopausal women with MetS and vasomotor symptoms taking one sachet per day of the dietary supplement INOFOLIC® NRT (Farmares srl, Rome, Italy) were collected. Each sachet consisted of myo-Inositol (2000 mg), cocoa polyphenols (30 mg), and soy isoflavones (80 mg, of which 50 mg is genistin). Patients recorded their symptoms through a medical questionnaire at the beginning of the administration (T0) and after 6 months (T1). Results: We observed an improvement in both the frequency and the severity of hot flushes: increased percentage of 2-3 hot flushes (28 at T0 vs. 65% at T1, p value < 0.001) and decreased percentage of 4-9 hot flushes (54% at T0 vs. 18% at T1, p value < 0.001). Moreover, symptoms of depression improved after supplementation (87% at T0 vs. 56% at T1 of patients reported moderate depression symptoms, p value < 0.001). Regarding metabolic profile, women improved body mass index and waist circumference with a reduction in the percentage of overweight and obesity women (88% at T0 vs. 51% at T1, p value = 0.01; 14% at T0 vs. 9% at T1, p value = 0.04). In addition, the number of women suffering from non-insulin dependent diabetes reduced (26% at T0 vs. 16% at T1, p value = 0.04). Conclusions: These data corroborate previously observed beneficial effects of the oral administration of myo-Inositol, cocoa polyphenols, and soy isoflavones against menopausal symptoms in the study population. Considering the promising results of the present study, further prospective controlled clinical trials are needed to deeply understand and support the efficacy of these natural compounds for the management of menopausal symptoms.

OBJECTIVE: We investigated the systemic arterial hypertension effects on cardiovascular autonomic modulation and baroreflex sensitivity (BRS) in women with or without preserved ovarian function. METHODS: A total of 120 women were allocated into two groups: middle-aged premenopausal women (42 ± 3 y old; n = 60) and postmenopausal women (57 ± 4 y old; n = 60). Each group was also divided into two smaller groups (n = 30): normotensive and hypertensive. We evaluated hemodynamic and anthropometric parameters, cardiorespiratory fitness, BRS, heart rate variability (HRV), and blood pressure variability. The effects of hypertension and menopause were assessed using a two-way analysis of variance. Post hoc comparisons were performed using the Student-Newman-Keuls test. RESULTS: Comparing premenopausal groups, women with systemic arterial hypertension showed lower BRS (9.1 ± 4.4 vs 13.4 ± 4.2 ms/mm Hg, P < 0.001 ) and HRV total variance (1,451 ± 955 vs 2,483 ± 1,959 ms 2 , P = 0.005) values than normotensive; however, the vagal predominance still remained. On the other hand, both postmenopausal groups showed an expressive reduction in BRS (8.3 ± 4.2 vs 11.3 ± 4.8 ms/mm Hg, P < 0.001) and HRV characterized by sympathetic modulation predominance (low-frequency oscillations; 56% ± 17 vs 44% ± 17, P < 0.001), in addition to a significant increase in blood pressure variability variance (28.4 ± 14.9 vs 22.4 ± 12.5 mm Hg 2 , P = 0.015) compared with premenopausal groups. Comparing both postmenopausal groups, the hypertensive group had significantly lower values ​​of HRV total variance (635 ± 449 vs 2,053 ± 1,720 ms 2 , P < 0.001) and BRS (5.3 ± 2.8 vs 11.3 ± 3.2 ms/mm Hg) than the normotensive. CONCLUSIONS: Hypertensive middle-aged premenopausal women present HRV autonomic modulation impairment, but they still maintain a vagal predominance. After menopause, even normotensive women show sympathetic autonomic predominance, which may also be associated with aging. Furthermore, postmenopausal women with hypertension present even worse cardiac autonomic modulation.

OBJECTIVE: The severity of menopausal symptoms, despite being triggered by hormonal imbalance, does not directly correspond to hormone levels in the blood; thus, the level of unpleasantness is assessed using subjective questionnaires in clinical practice. To provide better treatments, alternative objective assessments have been anticipated to support medical interviews and subjective assessments. This study aimed to develop a new objective measurement for assessing unpleasantness. METHODS: Fourteen participants with menopausal symptoms and two age-matched participants who visited our outpatient section were enrolled. Resting-state brain activity was measured using magnetoencephalography. The level of unpleasantness of menopausal symptoms was measured using the Kupperman Kohnenki Shogai Index. The blood level of follicle-stimulating hormone and luteinizing hormone were also measured. Correlation analyses were performed between the oscillatory power of brain activity, index score, and hormone levels. RESULTS: The level of unpleasantness of menopausal symptoms was positively correlated with high-frequency oscillatory powers in the parietal and bordering cortices (alpha; P = 0.016, beta; P = 0.015, low gamma; P = 0.010). The follicle-stimulating hormone blood level was correlated with high-frequency oscillatory powers in the dorsal part of the cortex (beta; P = 0.008, beta; P = 0.005, low gamma; P = 0.017), whereas luteinizing hormone blood level was not correlated. CONCLUSION: Resting-state brain activity can serve as an objective measurement of unpleasantness associated with menopausal symptoms, which aids the selection of appropriate treatment and monitors its outcome.

Navigating menopause involves traversing a complex terrain of hormonal changes that extend far beyond reproductive consequences. Menopausal transition is characterized by a decrease in estradiol-17ß (E2), and the impact of menopause resonates not only in the reproductive system but also through the central nervous system, musculoskeletal, and gastrointestinal domains. As women undergo menopausal transition, they become more susceptible to frailty, amplifying the risk and severity of injuries, including traumatic brain injury (TBI). Menopause triggers a cascade of changes leading to a decline in muscle mass, accompanied by diminished tone and excitability, thereby restricting the availability of irisin, a crucial hormone derived from muscles. Concurrently, bone mass undergoes reduction, culminating in the onset of osteoporosis and altering the dynamics of osteocalcin, a hormone originating from bones. The diminishing levels of E2 during menopause extend their influence on the gut microbiota, resulting in a reduction in the availability of tyrosine, tryptophan, and serotonin metabolites, affecting neurotransmitter synthesis and function. Understanding the interplay between menopause, frailty, E2 decline, and the intricate metabolisms of bone, gut, and muscle is imperative when unraveling the nuances of TBI after menopause. The current review underscores the significance of accounting for menopause-associated frailty in the incidence and consequences of TBI. The review also explores potential mechanisms to enhance gut, bone, and muscle health in menopausal women, aiming to mitigate frailty and improve TBI outcomes.

INTRODUCTION: For many women, menopause transition can be a period of emotional and physical changes, with different menopausal stages associated with varied risk for depressive symptoms and diagnosis. This review aimed to conduct a systematic review and meta-analyses to provide an estimate for the risk of developing a) clinical depression and b) depressive symptoms at different menopausal stages. METHODS: We searched Medline, PsycInfo, Embase and Web of Science from inception to July 2023. Seventeen prospective cohort studies with a total of 16061 women were included in the review, and risk of bias was assessed using the Quality in Prognosis Studies tool (QUIPS). Seven papers with a total of 9141 participants were included in meta-analyses, using random effects models and pooled odds ratios (OR) calculated for depressive symptoms and diagnoses. RESULTS: Perimenopausal women were found to be at a significantly higher risk for depressive symptoms and diagnoses, compared to premenopausal women (OR = 1.40; 95 % CI: 1.21; 1.61, p < .001). We did not find a significantly increased risk for depressive symptoms or diagnoses in post-menopausal, compared to pre-menopausal women. LIMITATIONS: Studies used different criteria to classify the menopausal stages and different measures for depression, which may have contributed to the heterogeneity seen in some models. We were unable to include a model that compared peri to post-menopause, due to a lack of longitudinal studies comparing the two stages. CONCLUSIONS: The risk of depression in perimenopause, shown in an ethnically diverse sample; highlights the clinical need for screening and support in this potentially vulnerable group.

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.

Fluctuations in sex hormones at different stages of reproductive life, such as the menopausal transition, have been suggested as players in weight regulation. Indeed, the transition from a predominantly estrogenic state to an androgenic state characteristic of the menopausal transition contributes to changes in body composition with accumulation of fat and simultaneous loss of lean mass. However, whether these changes contribute to the weight gain remains debatable. Other physiological and psychosocial factors come into play. It is therefore important to offer individualized support with the objective to minimize the risk of weight gain and associated complications.


La fluctuation des hormones sexuelles à différentes étapes de la vie reproductive, telles que la transition ménopausique, a été proposée comme une des composantes de la régulation de poids. Effectivement, le passage d'un état principalement œstrogénique à un état androgénique, caractéristique de la transition ménopausique, contribue à des modifications de la composition corporelle avec une accumulation de graisse et une perte simultanée de masse maigre. Cependant, la question de savoir si ces changements contribuent à une prise de poids reste discutable. L'obésité est une maladie multifactorielle et d'autres facteurs d'ordre physiologique et psychosociaux rentrent en jeu. Il est donc important d'offrir un accompagnement individualisé aux femmes concernées pour les aider à minimiser le risque de prise pondérale et des complications associées.

IMPORTANCE: Vasomotor symptoms (VMS) affect many postmenopausal persons and impact sleep and quality of life. OBJECTIVE: This systematic review examines the literature describing the safety and efficacy of neurokinin-3 receptor antagonists approved and in development for postmenopausal persons with VMS. EVIDENCE REVIEW: A search of MEDLINE, EMBASE, and International Pharmaceutical Abstracts was conducted using the search terms and permutations of neurokinin-3 receptor antagonist, elinzanetant, fezolinetant, and osanetant. Inclusion criteria of reporting on efficacy or safety of fezolinetant, elinzanetant, or osanetant; studies in participants identifying as female; full record in English; and primary literature were applied. Abstract-only records were excluded. Extracted data were synthesized to allow comparison of reported study characteristics, efficacy outcomes, and safety events. Eligible records were evaluated for risk of bias via the Cochrane Risk of Bias 2 tool for randomized studies and the Grading of Recommendations Assessment, Development and Evaluation system was used. This study was neither funded nor registered. FINDINGS: The search returned 191 records; 186 were screened after deduplication. Inclusion criteria were met by six randomized controlled trials (RCT), four reported on fezolinetant, and two reported on elinzanetant. One record was a post hoc analysis of a fezolinetant RCT. An additional study was identified outside the database search. Three fezolinetant RCT demonstrated a reduction in VMS frequency/severity, improvement in Menopause-Specific Quality of Life scores, and improvement in sleep quality at weeks 4 and 12 compared with placebo without serious adverse events. The two RCT on elinzanetant also showed improvements in VMS frequency and severity. All eight records evaluated safety through treatment-emergent adverse events; the most common adverse events were COVID-19, headache, somnolence, and gastrointestinal. Each record evaluated had a low risk of bias. There is a strong certainty of evidence as per the Grading of Recommendations Assessment, Development and Evaluation system. CONCLUSIONS AND RELEVANCE: Because of the high-quality evidence supporting the efficacy of fezolinetant and elinzanetant, these agents may be an effective option with mild adverse events for women seeking nonhormone treatment of VMS.

Understanding how and why menopause has evolved is a long-standing challenge across disciplines. Females can typically maximize their reproductive success by reproducing for the whole of their adult life. In humans, however, women cease reproduction several decades before the end of their natural lifespan1,2. Although progress has been made in understanding the adaptive value of menopause in humans3,4, the generality of these findings remains unclear. Toothed whales are the only mammal taxon in which menopause has evolved several times5, providing a unique opportunity to test the theories of how and why menopause evolves in a comparative context. Here, we assemble and analyse a comparative database to test competing evolutionary hypotheses. We find that menopause evolved in toothed whales by females extending their lifespan without increasing their reproductive lifespan, as predicted by the 'live-long' hypotheses. We further show that menopause results in females increasing their opportunity for intergenerational help by increasing their lifespan overlap with their grandoffspring and offspring without increasing their reproductive overlap with their daughters. Our results provide an informative comparison for the evolution of human life history and demonstrate that the same pathway that led to menopause in humans can also explain the evolution of menopause in toothed whales.

The causes of vasomotor symptoms, including hot flashes, are not fully understood, may be related to molecular factors, and have a polygenic architecture. Nutrients and bioactive molecules supplied to the body with food are metabolized using various enzymatic pathways. They can induce molecular cell signaling pathways and, consequently, activate effector proteins that modulate processes related to hot flashes in menopausal women. In this review, we analyzed the literature data from the last 5 years, especially regarding genome-wide association study (GWAS) analysis, and selected molecular factors and cell signaling pathways that may potentially be related to hot flashes in women. These are the kisspeptin-GnRH pathway, adipocyte-derived hormones, aryl hydrocarbon receptor signaling, catechol estrogens and estrogen sulfotransferase, inflammatory and oxidative stress biomarkers, and glucose availability. Then, single compounds or groups of food ingredients were selected that, according to experimental data, influence the course of the discussed molecular pathways and thus can be considered as potential natural therapeutic agents to effectively reduce the troublesome symptoms of menopause in women.
