The effect of physical activity and body mass index on menopausal symptoms in Turkish women: a cross-sectional study in primary care

Prevalence of menopausal symptoms and attitudes towards menopausal hormone therapy in women aged 40-60 years: a cross-sectional study

BACKGROUND

Menopause is a specific physical and psychological transition period for women, during which they experience a series of menopausal symptoms. Menopausal hormone therapy is an important treatment for improving menopausal symptoms. Helping women correctly understand menopausal hormone therapy is a prerequisite for increasing the acceptance and utilization of menopausal hormone therapy by women. Physical examinations are an important method for women to master their own health status and detect potential health problems, and in recent years, an increasing number of women have actively participated in physical examinations. Therefore, this study aims to comprehend the prevalence of menopausal symptoms and attitudes towards menopausal hormone therapy among women aged 40-60 who underwent physical examinations, which would provide a useful reference to reduce the prevalence of menopausal symptoms and improve acceptance of menopausal hormone therapy.

METHODS

This cross-sectional study was conducted at the Health Management Centre of the Affiliated Hospital of Southwest Medical University in Luzhou City, Sichuan Province. The data were collected from 295 women aged between 40 and 60 using convenience sampling. Information on all participants was collected through face-to-face interviews. Participants completed a demographic questionnaire and an attitude towards menopausal hormone therapy questionnaire, and the modified Kupperman index was used to assess the prevalence and severity of participants' menopausal symptoms. The collected data were processed using SPSS and Excel software and analysed using descriptive statistics and logistic regression.

RESULTS

The top 5 menopausal symptoms were insomnia, fatigue, bone and joint pain, sexual dysfunction and emotional instability. Multiple linear regression analysis showed that residence, sexual intercourse frequency, mentality, and physical exercise were the influencing factors of menopausal symptoms. The study showed that 77% of women said they were still reluctant to receive menopausal hormone therapy after experiencing menopause-related symptoms. The main source of menopausal hormone therapy-related knowledge among women was from surrounding menopausal women (62%), and 54% wanted to gain menopausal hormone therapy-related knowledge through a web-based approach.

CONCLUSION

The incidence of menopausal symptoms is higher in women aged 40-60 years, which is related to women's mentality, exercise, and sexual intercourse frequency. In addition, the results of this study indicate that women's knowledge of menopausal hormone therapy is insufficient, which suggests that we need to strengthen health education to improve the acceptance rate of menopausal hormone therapy.

Prevalence of hypertension and correlation with mental health in women with burning mouth syndrome: A case-control study

Background

The relationship between hypertension (HTN) and chronic pain is still a matter of debate, and its prevalence in patients with burning mouth syndrome (BMS) has never been evaluated. This study aimed to assess the prevalence of HTN in women with BMS and to evaluate its relationship with potential predictors such as risk factors for cardiovascular diseases, pain, and mental health status analyzing differences with healthy women.

Methods

In total, 250 women with BMS (WBMS) were prospectively recruited and compared with an equal number of healthy women (HW) matched for age. Education, body mass index, smoke and alcohol consumption, intensity and quality of pain, and psychological profile were further investigated to identify the potential predictors of HTN. Specifically, pain assessment [the Numeric Rating Scale (NRS) and Short-Form McGill Pain Questionnaire (SF-MPQ)] and psychological assessment [Hamilton Rating Scale for Depression and Anxiety (HAM-D and HAM-A), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS)] was carried out for the participants.

Results

HTN was found in 128 (51.2%) WBMS and 76 (30.4%) HW (p < 0.001^**). The scores of the NRS, SF-MPQ, HAM-D, HAM-A, and PSQI were statistically significantly higher in the WBMS than in the HW (p < 0.001^**). A strongly linear correlation between HTN and employment status, systemic diseases, and education level (p < 0.001^**) was found in WBMS, while a strong correlation between HTN and employment status, hypercholesterolemia, systemic diseases, and drug consumption was found in HW (p < 0.001^**). No statistically significant correlation was found between HTN and pain, anxiety, depression, and sleep disturbances.

Conclusion

These results suggest that WBMS showed a higher prevalence of HTN compared with controls. Unemployed WBMS with lower education and other systemic comorbidities are at an increased risk of developing HTN. HTN is associated with alteration in the vascular structure and function of the brain, and these processes accelerate brain aging, which contributes to a reduction in intracortical connectivity, thus affecting the modulatory system of control of pain in patients with BMS, independently of their mental health assessment. Predictors that may underlie this association remain unclear, taking into account the differences found in HW, and should be further elucidated.

Effectiveness of Educational Intervention Based on Transtheoretical Model on Physical Activity and Menopausal Symptoms

Introduction

Menopause is an inevitable part of women's lives. Physical activity as nonhormonal therapy can decrease the symptoms of menopause. This study is aimed at investigating the effect of educational intervention based on the transtheoretical model (TTM) on physical activity and menopausal symptoms of female clients of the health center in Pasargad City, Iran.

Methods

This quasi-experimental study was performed on 140 females admitted to health center of Pasargad City, Fars Province, Iran (intervention = 70 and control = 70). The data collection tool consisted of demographic data, menopause rating scale, international physical activities questionnaire, and TTM questionnaire (stages of change, processes of change, decision-making balance, and self-efficacy) that were completed before and two months after intervention. For intervention group, the educational program was implemented during 5 sessions of 50-55 min. Data were analyzed by SPSS 25 and by using Chi-square test, independent t-test, and paired t-test.

Results

After intervention, the mean scores of physical symptoms are sleep problems, muscle problems and discomfort, psychological symptoms, depression, irritability, and anxiety of intervention group decreased significantly post intervention (p < 0.001). Analysis showed that psychological symptoms, mental fatigue, somatic, and urogenital symptoms, and vaginal dryness increased 2 months after the intervention. Also, the mean score of cons, pros, decision balance, self-efficacy, consciousness raising, dramatic relief, environmental reevaluation, and self-reevaluation have significant changed in intervention group (p < 0.05). In addition, the top percent of progress can be seen in contemplation (31. 5%).

Conclusion

This study showed the effectiveness of educational intervention based on TTM to reduce menopausal symptoms and promote physical activity in postmenopausal women.

Does social support affect menopausal symptoms in menopausal women?

PURPOSE

To determine the effect of perceived social support of menopausal women on their menopausal complaints.

DESIGN AND METHODS

This descriptive and correlational study was conducted with 505 women. The data were obtained using personal information form, menopause rating scale, and multidimensional scale of perceived social support. Frequency, percentage, t test, analysis of variance Skewness and Kurtosis (±1) and correlation were used in the analysis of the data.

FINDINGS

In the study, it was found that there was a positive and significant relationship between menopausal symptoms and social support, and menopausal symptoms decreased as social support increased.

PRACTICE IMPLICATIONS

Nurses should provide consultancy for women to increase their social support systems to decrease their menopausal complaints.

Correlates of palpitations during menopause: A scoping review

Objective:

Palpitations during peri- and post-menopause are common. It is unclear what variables are related to palpitations in peri- and post-menopausal women. The purpose of this scoping review was to summarize potential correlates of palpitations in women transitioning through menopause.

Methods:

The review followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Authors included English-language, full-length, peer-reviewed, cross-sectional research articles on palpitations in menopausal women published through December 18, 2021, from PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and PsycINFO searches. Following de-duplication, screening of titles and abstracts, and review of full-texts, independent reviewers extracted data on variables studied in relationship to palpitations from 84 articles and resolved discrepancies. Authors extracted data on (1) demographic, clinical, biomarker, and symptom/quality of life variables and (2) data analysis method (bivariate, multivariate). Authors classified each variable as a likely, unlikely, or unclear correlate of palpitations.

Results:

Articles were diverse in region of origin, sample sizes, and variables assessed in relationship to palpitations. Evidence for any one variable was sparse. Likely correlates of palpitations included race/ethnicity, lower physical activity, worse vasomotor symptoms (VMSs), worse sleep, and worse quality of life. Unlikely correlates included age, employment, education, marital status, socioeconomic status, comorbidities, body mass index, and sexual difficulties. Unclear correlates due to equivocal evidence were menopausal status, smoking, and depression. Unclear correlates due to insufficient evidence (less than three articles) included all of the assessed biomarkers, anxiety, and stress.

Conclusion:

Likely correlates were identified including race/ethnicity, physical activity, VMS, sleep, and quality of life. However, additional research is needed to better understand potential correlates of palpitations.

Prevalence of menopausal hot flashes in Lebanon: A cross-sectional study

Background

Menopausal hot flashes or vasomotor symptoms are prevalent and could be debilitating in postmenopausal women. There is controversy regarding the risk factors for hot flashes, some of which may vary from one country or culture to another.

Objective

To shed light on this matter by assessing the prevalence of hot flashes, their effect on quality of life, and their association with certain factors such as physical exercise, caffeine, spicy food consumption, dietary intake, smoking, alcohol, etc.

Materials and Methods

A large cross-sectional study was conducted among 627 Lebanese women, aged 45-67 yr using a well-developed and comprehensive questionnaire, in order to better assess the prevalence of hot flashes, focusing on their characteristics, association with various factors, severity, and effect on the women's quality of life.

Results

62.5% of participants experienced hot flashes. A statistically significant difference was noted between women who experience hot flashes and their counterparts with respect to smoking, body mass index, spicy food consumption, education level, age, menstrual status, and parity. An association was not found with physical activity or other dietary factors.

Conclusion

As an alternative for hormone therapy, clinicians should consider lifestyle changes to help manage hot flashes, which impose a tremendous physical and social toll on the women experiencing them.

The effect of physical activity and depressive mood on menopausal symptoms in postmenopausal women

AIMS

The symptoms of menopause in postmenopausal women adversely affect the quality of life. Menopausal symptoms are more severe with comorbid disorders such as depression; it may be lighter in physically active people. The present study aimed to evaluate the relationship between menopausal symptoms and physical activity and depressive mood.

MATERIAL AND METHOD

One hundred and ninety women under 65 years of age who were at least 1 year passed since their last menstrual period participated in the study. Sociodemographic data form, Menopause Symptom Rating Scale, International Physical Activity Questionnaire-Short Form and Beck's Depression Inventory were applied to the participants.

RESULTS

It was seen that 51.6% (98 subjects) of the women who participated in the study had severe menopausal symptoms. 52.6% (100 subjects) of the participants were physically inactive, and their menopausal symptoms increased as the physical activity scale score decreased (P = .001). Menopausal symptoms increased as the Beck's Depression Inventory score increased (P < .001). It was observed that depression inventory scores decreased as the level of physical activity increased (P < .001).

CONCLUSION

Adoption of regular physical activity habits by postmenopausal women and providing treatment to those with depression will contribute to alleviating the severity of menopausal symptoms.

Review of menopausal palpitations measures

Palpitations are reported commonly by women around the time of menopause as skipped, missed, irregular, and/or exaggerated heartbeats or heart pounding. However, much less is known about palpitations than other menopausal symptoms such as vasomotor symptoms. The objective of this review was to integrate evidence on menopausal palpitations measures. Keyword searching was done in PubMed, CINAHL, and PsycINFO for English-language, descriptive articles containing data on menopause and palpitations and meeting other pre-specified inclusion criteria. Of 670 articles, 110 met inclusion criteria and were included in the review. Results showed that 11 different measures were used across articles, with variability within and between measures. Inconsistencies in the wording of measurement items, recall periods, and response options were observed even when standardized measures were used. Most measures were limited to assessing symptom presence and severity. Findings suggest that efforts should be undertaken to (1) standardize conceptual and operational definitions of menopausal palpitations and (2) develop a patient-friendly, conceptually clear, psychometrically sound measure of menopausal palpitations.

The association between physical activity and menopause-related quality of life

Background/aims

Menopause can cause drastic changes that trigger severe symptoms in women and, in turn, influence their quality of life. Many women no longer prefer hormone replacement therapy because of its potential adverse effects. Hence, it is crucial to establish alternate interventions to alleviate menopausal symptoms. The aim of this study was to estimate the relationship between quality of life and level of physical activity in menopausal women.

Methods

A total of 260 postmenopausal women were recruited in this cross-sectional study. The Menopause Rating Scale and International Physical Activity Questionnaire – Short Form were used to assess quality of life and physical activity respectively.

Results

Women with higher levels of physical activity had fewer total menopausal, somato-vegetative and psychological symptoms (P<0.001); no differences were found in vasomotor and urogenital symptoms.

Conclusions

Women with low physical activity levels presented with greater menopausal symptoms. Regular physical activity can be recommended to alleviate symptoms following menopause, thereby improving quality of life.

The associations of childhood adiposity with menopausal symptoms in women aged 45-49 years: An Australian Cohort Study

OBJECTIVES

To examine the associations of childhood adiposity with menopausal symptoms in women aged 45-49 years.

STUDY DESIGN

National population-based cohort study of 334 girls prospectively followed from childhood (aged 11-15) through to midlife (aged 45-49). Childhood overweight and obesity were defined by international age- and sex-specific standards for body mass index (BMI), and abdominal obesity was defined as waist/height ratio≥0.5.

MAIN OUTCOME MEASURES

Vasomotor symptoms (VMS), vaginal dryness, total menopausal symptoms and domain-specific symptoms (somatic, psychological and urogenital) were measured during 2018-19 using the Menopause Rating Scale (MRS) and classified as none, mild, moderate or severe.

RESULTS

The prevalence of mild, moderate and severe VMS was 24.0 %, 9.0 % and 3.9 %, and of vaginal dryness was 12.6 %, 4.8 % and 2.4 %. No significant associations of childhood overweight/obesity or abdominal obesity with VMS or vaginal dryness were found after adjustment for childhood age, follow-up length, smoking, socioeconomic status and diet quality. Childhood overweight/obesity was associated with increased risks of more severe total (RR:1.17, 95 % CI:1.02-1.36), psychological (RR:1.19, 95 % CI:1.04-1.35) and urogenital (RR:1.29, 95 % CI:1.14-1.46) symptoms measured using the MRS. Associations with childhood abdominal obesity were mostly stronger with more severe total (RR:2.19, 95 % CI:1.48-3.23), somatic (RR:1.52, 95 % CI:1.15-2.02), psychological (RR:1.21, 95 % CI:1.04-1.42) and urogenital (RR:2.11, 95 % CI:1.39-3.20) symptoms.

CONCLUSIONS

Childhood adiposity was not associated with increased risks of more severe VMS or vaginal dryness in women aged 45-49 years. Childhood adiposity, especially abdominal obesity, was associated with more severe total, somatic, psychological and urogenital symptoms. However, the association between these symptoms and menopause is not established.

Symptoms at midlife among women in Nagaland, India

OBJECTIVES

This article highlights the prevalence of symptom frequencies in Nagaland, India, with a focus on depressed mood and hot flashes. We also examine how symptoms cluster together among Naga women and identify factors associated with symptom experience. We hypothesized an elevated frequency of depressed mood because of the stresses associated with social responsibilities within a patriarchal culture, and a low frequency of hot flashes because of the thinness of the population.

METHODS

Standardized questionnaires with close-ended questions were used to determine the frequency of symptoms and sociodemographic and health parameters among women aged 35 to 65 years (n = 352). Factor analysis was used to examine the relations among symptoms. Bivariate analyses and linear regressions were also employed to identify sociodemographic and health factors associated with symptoms.

RESULTS

Menopausal symptoms, such as feeling dizzy or faint, anxiety or panic, and excitable, were significantly higher in premenopausal women; hot flashes in perimenopausal women; and feeling tired or lack in energy, headaches, difficulty in sleeping, and muscle or joint pain in postmenopausal women. Four symptom factors were identified: symptoms related to the loss of estradiol, psychosomatic symptoms, uneasiness, and depressed mood. After adjusting for menopausal status, socioeconomic status, education, and self-reported health status, body mass index was observed to be inversely associated with the depressed mood factor but not other factors.

CONCLUSION

In the context of Nagaland, India, having extra weight may contribute to emotional well-being; however, further research is warranted.

Associations Among BMI, Dietary Macronutrient Consumption, and Climacteric Symptoms in Korean Menopausal Women

Many postmenopausal women individually experience varying degrees of climacteric symptoms. Among the many influencing factors, body weight and diet are recognized as important contributors to the incidence and severity of these symptoms. This study was performed to investigate the interaction effect of BMI (body mass index) and dietary consumption on the risk of climacteric symptoms among Korean women. Approximately half of the subjects (48.8%) experienced climacteric symptoms. After adjusting for the covariates, the subjects who are overweight or obese showed significantly greater total scores of climacteric symptoms (p = 0.010) and subscales of symptoms (p = 0.027 for physical climacteric symptoms and p = 0.007 for psychological climacteric symptoms), except for urogenital climacteric symptoms (p = 0.085), than those subjects at a normal weight. When subjects were divided into groups according to dietary macronutrient consumption, those who are overweight or obese were 2.84-fold (adjusted odds ratio, 95% CI = 1.18-6.80, p = 0.019) more likely to experience climacteric symptoms than those at a normal weight among the subjects with high fat consumption. However, the BMI category did not affect the adjusted odds ratio for experiencing climacteric symptoms among subjects who consumed a low-fat diet.

Age of Natural Menopause and Related Factors among the Tabari Cohort

OBJECTIVES

The age of menopause is affected by several factors. In this study we aimed to identify the age of natural menopause and its related factors in a large-scale population-based cohort in Iran.

METHODS

In this study, a subset of data collected during the enrollment phase of the Tabari cohort study was utilized. Reproductive history and other related data were collected using a structured questionnaire. Blood samples were obtained from all participants. Data were analyzed using chi-square test, independent t test, and ANOVA as well as a multivariate linear regression model.

RESULTS

Among participants of the Tabari cohort, 2,753 were menopausal women. The mean age of natural and induced menopause was 49.2 ± 4.7 and 43.2 ± 6.4 years, respectively (P = 0.001). The number of pregnancies, duration of breastfeeding, level of education, residency, presence of thyroid disease, and body mass index affected the age of menopause. After adjustments for confounding variables, the number of pregnancies remained significantly associated with late menopause.

CONCLUSIONS

The age of natural menopause in this study was similar to that in other studies, and the number of pregnancies was positively associated with the age of menopause after adjustments for confounding variables.

Obesity associates with vasomotor symptoms in postmenopause but with physical symptoms in perimenopause: a cross-sectional study

BACKGROUND

Middle-aged women experience various menopausal symptoms during the menopause. These symptoms can affect their quality of life and health. Several epidemiological studies reported that obesity associates with menopausal symptoms. The aim of this cross-sectional study was to examine the associations between obesity and multiple menopausal symptoms at different stages of menopause in middle-aged Korean women.

METHODS

The study population included women aged 44-56 years who visited a tertiary referral hospital for medical check-ups between November 2012 and March 2013 and were free from serious illness, could comprehend a questionnaire. The Menopause-Specific Quality of Life (MENQOL) questionnaire was used to assess the prevalence of menopausal symptoms. Overweight and obesity were defined as body mass index (BMI) of 23-24.9 and ≥25 kg/m2, respectively.

RESULTS

Of the 2204 middle-aged women, 929 met the eligibility criteria. Of these, 533 (57.4%) and 396 (42.6%) were in perimenopause and postmenopause, respectively. In perimenopause, obese women were significantly more likely to have moderate/severe physical symptoms (MENQOL domain score ≥ 5) than normal or overweight women. In postmenopause, obese women were significantly more likely to have moderate/severe vasomotor symptoms. Multiple linear regression with adjustment for confounders showed that relative to normal weight, obesity in perimenopause and postmenopause associated independently with physical symptoms (beta coefficient = 0.35; P = 0.023) and vasomotor symptoms (beta coefficient = 0.68; P = 0.003), respectively. Overweight did not associate with menopausal symptoms. BMI did not associate significantly with psychosocial or sexual symptoms at either stage of menopause.

CONCLUSIONS

Obese women had more frequent menopausal symptoms than normal or overweight women but the associated menopausal symptom differed depending on the menopausal stage. Further studies are required to confirm this result and identify the underlying mechanisms.

The effect of Valerian on the severity and frequency of hot flashes: A triple-blind randomized clinical trial

Valerian is one of the most widely used herbal supplements and a phytoestrogenic herb. The aim of this study was to determine the effect of Valerian on the severity and frequency of hot flashes. This triple-blind, randomized, controlled clinical trial was conducted during a three-month period in Hamadan, Iran, in 60 postmenopausal women aged 45-55 years. Participants were randomly assigned to one of two groups- either placebo or Valerian. An oral Valerian 530 mg capsule was given twice per day for two months. An oral placebo 530 mg capsule (starch) was similarly administered. The severity and frequency of hot flashes were determined by the Kupperman index, before the intervention, one month after, and two months after initiation of the intervention. The severity of hot flashes in the Valerian group was significantly lower than that in the placebo group at one (p = .048) and two months (p = .020) after initiation of the intervention. Compared with the placebo group, the mean frequency of hot flashes was significantly reduced two months after initiating the use of Valerian (p = .033). Health-care providers should consider Valerian to be effective for menopausal women with hot flashes.

The Association between Body Mass Index and Hot Flash in Midlife Women: A Meta-analysis

Objectives

The association between body mass index (BMI) and hot flash risk has not been specifically clarifies yet. This meta-analysis was, therefore, conducted to estimate the association between overweight and obesity and hot flash risk.

Methods

We searched PubMed, Web of Science, and Scopus for observational studies addressing the association between BMI and hot flash until August 2015. Data were independently extracted and analyzed using 95% odds ratio (OR), and confidence intervals (CI) based on the random-effects models.

Results

We identified 2,244 references and conducted seven studies with 4,219 participants. The association between hot flash and overweight was estimated 1.13 (95% CI: 0.97-1.32) and that of obesity was estimated 1.79 (95% CI: 1.52-2.11). No evidence of heterogeneity and publication bias was observed.

Conclusion

This meta-analysis demonstrated that, though not to a great extent, obesity does increase the risk of hot flash. The findings from this meta-analysis indicated that obesity is associated with an increased risk of hot flash. Further large prospective cohort studies are required to provide convincing evidence as to whether or not BMI is associated with an increased risk of hot flashes.

Difference in blood pressure between early and late menopausal transition was significant in healthy Korean women

Background

Although the prevalence of hypertension is higher in postmenopausal women than in premenopausal women, little is known about changes in blood pressure (BP) during the menopausal transition. We evaluated BP according to the menopausal transition and associated factors in healthy Korean women.

Methods

This cross-sectional study involved 2037 women aged 44 to 56 years who presented at a health-screening center in Seoul, Korea, from November 2012 to March 2013. The association between BP and menopausal transition and the risk factors related to elevated BP were determined using multiple linear regression analyses. Menopausal status was divided by four groups as premenopause, early menopausal transition, late menopausal transition and postmenopause.

Results

Both systolic and diastolic blood pressure (SBP and DBP) differed significantly according to the menopausal status. BP showed the greatest difference between early and late menopausal transition. After adjusting for variables related to hypertension, SBP (β = 2.753, p < 0.01) and DBP (β = 1.746, p = 0.02) were significantly higher in late than early menopausal transition. The prevalence of hypertension was significantly different between early and late menopausal transition (1.4 vs. 6.1 %). Waist circumference, glucose, and triglycerides were positively and significantly associated with SBP and DBP during menopause.

Conclusions

BP and the prevalence of hypertension were significantly associated with period between early and late menopausal transition, suggesting that changes in BP during the menopausal transition are significant. Therefore, frequent monitoring will be needed for early detection of hypertension during the menopausal transition.

Recent evidence exploring the associations between physical activity and menopausal symptoms in midlife women: perceived risks and possible health benefits

Although the health benefits of physical activity are well established, the prevalence of midlife women accumulating sufficient physical activity to meet current physical activity guidelines is strikingly low, as shown in United States (U.S.) based surveillance systems that utilize either (or both) participant-reported and device-based (i.e., accelerometers) measures of activity. For midlife women, these low prevalence estimates may be due, in part, to a general lack of time given more pressing work commitments and family obligations. Further, the benefits or "reward" of allocating limited time to physical activity may be perceived, by some, as too distant for immediate action or attention. However, shifting the health promotion message from the long term benefits of physical activity to the more short-term, acute benefits may encourage midlife women to engage in more regular physical activity. In this article, we review the latest evidence (i.e., past 5 years) regarding the impact of physical activity on menopausal symptoms. Recent studies provide strong support for the absence of an effect of physical activity on vasomotor symptoms; evidence is still inconclusive regarding the role of physical activity on urogenital symptoms (vaginal dryness, urinary incontinence) and sleep, but consistently suggestive of a positive impact on mood and weight control. To further advance this field, we also propose additional considerations and future research directions.

Cost-effectiveness of physical activity among women with menopause symptoms: findings from a randomised controlled trial

Menopause is a period that may predispose one to a decrease in muscle strength, cardiorespiratory fitness, and quality of life. A study was carried out to evaluate the cost-effectiveness of physical activity among women displaying symptoms of menopause. The cost-effectiveness analysis was based on data from a six-month randomised controlled trial (n = 151). The women in the intervention group engaged in an unsupervised session of at least 50 minutes of physical activity four times a week. The control group continued their physical activity as before. An incremental cost-effectiveness ratio (ICER) was calculated in terms of maximal oxygen consumption, lean muscle mass, and quality-adjusted life years (QALYs) gained. A bootstrap technique was utilised to estimate uncertainty around the point estimate for ICER associated with the intervention. The mean total cost in the intervention group was €1,307 (SEM: €311) and in the control group was €1,253 (SEM: €279, p = 0.10) per person. The mean intervention cost was €208 per person. After six months of the behaviour-change intervention, the ICER was €63 for a 1 ml/kg/min improvement in cardiorespiratory fitness, the additional cost per one-gram increase in lean muscle mass was €126, and the cost per QALY gained was €46. According to the findings, physical activity among menopausal women was cost-effective for cardiorespiratory fitness, for lean muscle mass, and for QALYs gained, since the intervention was more effective than the actions within the control group and the additional effects of physical activity were gained at a very low price. From the societal perspective, the intervention used may promote ability to work and thereby save on further costs associated with early retirement or disability pension if the physical-activity level remains at least the same as during the intervention.

Effects of Gengnianchun on learning and memory ability, neurotransmitter, cytokines, and leptin in ovariectomized rats

This study aimed to evaluate the beneficial effects of a traditional Chinese medicine named Gengnianchun (GNC) in ovariectomized Sprague-Dawley rats. The rats were randomly categorized into sham-operated group (Sham), saline-treated ovariectomized group (OVX), GNC-treated ovariectomized group (OVX+GNC), estradiol valerate-treated ovariectomized group (OVX+E). GNC and estradiol was administered for 1 month at dosages of 125 and 0.1 mg/day, respectively. Ovariectomy caused deterioration of learning and memory ability (P < 0.05), which was restored by treatment with GNC and estradiol (P < 0.05). Estrogen level and endometrial thickness significantly decreased in the OVX group (P < 0.05). These parameters significantly increased in the OVX+E group (P < 0.05) but did not change in the OVX+GNC group (P > 0.05). GNC and estradiol significantly increased the levels of norepinephrine (NE) and dopamine (DA) and decreased the levels of 5-hydroxytryptamine (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) in the hypothalamus (P < 0.05). The levels of interleukin-1 beta (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) significantly decreased and the levels of interleukin-2 (IL-2) and interferon-gamma (IFN-γ) increased in the OVX+GNC and OVX+E groups compared with those in the OVX group (P < 0.05). OVX rats treated with GNC and estradiol further exhibited reversed ovariectomy-induced weight gain and leptin resistance (P < 0.05). These results indicated that GNC demonstrated phytoestrogen-like properties without the side effects of estradiol valerate. Thus, GNC may confer protective and beneficial effects for management of menopausal syndrome.
