Abstract
Vasomotor symptoms (VMS), commonly called hot flashes or flushes (HFs) and night sweats, are the menopausal symptoms for which women seek treatment during menopause most often. VMS are a form of temperature dysfunction that occurs due to changes in gonadal hormones. Normally, core body temperature (CBT) remains within a specific range, oscillating with daily circadian rhythms. Physiological processes that conserve and dissipate heat are responsible for maintaining CBT, and tight regulation is important for maintenance of optimal internal organ function. Disruption of this tightly controlled temperature circuit results in exaggerated heat-loss responses and presents as VMS. The mechanistic role related to changes in gonadal hormones associated with VMS is not understood. Hormone therapy is the most effective treatment for VMS and other menopausal symptoms. Estrogens are known potent neuromodulators of numerous neuronal circuits throughout the central nervous system. Changing estrogen levels during menopause may impact multiple components involved in maintaining temperature homeostasis. Understanding the pathways and mechanisms involved in temperature regulation, probable causes of thermoregulatory dysfunction, and "brain adaptation" will guide drug discovery efforts. This review considers the processes and pathways involved in normal temperature regulation and the impact of fluctuating and declining hormones that result in VMS during the menopausal transition.

Abstract
OBJECTIVE To characterize the molecular mechanisms by which estrogens reduce adipose tissue mass, with particular focus on genes involved in lipogenesis. DESIGN This study involves one arm of an open randomized clinical study with parallel group comparison. SETTING Women's health clinical research unit at a university hospital and a university research laboratory. PATIENT(S) Samples from ten naturally postmenopausal women are included in the study. INTERVENTION(S) The participants were studied before and after 3 months of treatment with estradiol valerate (2 mg daily). MAIN OUTCOME MEASURE(S) Affymetrix gene chips were used to study changes in gene expression upon estrogen treatment in subcutaneous abdominal adipose tissue. RESULT(S) Genes involved in fatty acid synthesis, such as stearoyl-CoA desaturase, fatty acid synthase, acetyl-coenzyme A carboxylase alpha, and fatty acid desaturase 1 were decreased by estrogen treatment in a subgroup of women. Changes in the expression of these genes were correlated to changes in plasma triglyceride levels. Another gene decreased by estrogen treatment was peroxisome proliferator activated receptor gamma (PPARG). CONCLUSION(S) Key lipogenic genes and the important adipogenic gene PPARG can be regulated by estrogen in human abdominal adipose tissue, which could be relevant for increased adiposity following menopause.

Abstract
BACKGROUND Postmenopausal hormone therapy has been examined extensively in relation to cardiovascular disease. However, research relating serum levels of sex hormones to cardiovascular disease is sparse, and the results are inconclusive. METHODS We measured sex hormones in longitudinally collected samples of 180 postmenopausal women, 91 randomized to 17beta-estradiol and 89 to placebo, in the Estrogen in the Prevention of Atherosclerosis Trial. Repeated measures of sex hormone levels were tested for an association with carotid artery intima-media thickness (CIMT), which was also assessed longitudinally over 2 yr. RESULTS In all women, changes in serum estrone (P = 0.02), total estradiol (P = 0.01), free estradiol (P = 0.02), and SHBG (P = 0.005) were significantly inversely associated with CIMT progression, controlling for age and body mass index. All the estrogen compounds and SHBG were significantly inversely related with low-density lipoprotein cholesterol and positively associated with high-density lipoprotein cholesterol (all P < 0.0001), whereas free testosterone was positively related with low-density lipoprotein cholesterol and inversely associated with high-density lipoprotein cholesterol (P < 0.003). Despite an increase in serum-free estradiol with estradiol therapy, women with unchanged SHBG and free testosterone levels had an average (se) progression in CIMT of 8.53 (4.72) microm/yr, whereas women with increased free estradiol and SHBG and decreased free testosterone had the largest reduction in CIMT progression [-5.45 (2.77) microm/yr; trend P = 0.03]. CONCLUSION Estrogen and SHBG are associated with reduced subclinical atherosclerosis progression in healthy postmenopausal women. These associations are partially mediated by their beneficial effects on lipids. Among women taking estradiol, the most beneficial hormone profile for CIMT progression was increased free estradiol and SHBG with concomitant decreased free testosterone.

Abstract
OBJECTIVE To determine whether hot flashes, depressed mood, sleep, cognitive and sexual symptoms correlate with urinary follicle-stimulating hormone (FSH), estrone (E(1)G), and testosterone (T) and with each other during the menopausal transition and early postmenopause (PM). METHODS Forty-one women who transitioned from middle or late transition stage to PM rated symptoms and provided monthly urine specimens as part of a longitudinal study of the menopausal transition. RESULTS Correlations between endocrine levels and symptom severity ratings over time revealed that hot flash severity was significantly and positively related to FSH and negatively to E1 G. Vaginal dryness was positively correlated with FSH and negatively correlated with T. Decreased sexual desire was correlated negatively with E(1)G levels. Forgetfulness was positively correlated with FSH; difficulty concentrating was negatively correlated with T. Severity of sleep symptoms and depressed mood were not correlated with E(1)G, FSH, or T. Correlations among the symptoms revealed that severity of hot flashes was associated with sleep disruption and forgetfulness. Depressed mood was correlated with sleep disruption, difficulty concentrating, and decreased sexual desire but not with hot flashes or vaginal dryness. Awakening during the night was correlated with decreased sexual desire and vaginal dryness, as well as hot flashes. Forgetfulness was associated with hot flashes and difficulty concentrating, whereas difficulty concentrating was associated with depressed mood and early awakening. CONCLUSIONS Symptoms many women experience during the menopausal transition and early PM are related to different endocrine levels (FSH, E(1)G, and T).

Abstract
AIMS To examine the experience of menopause in Indian women (aged 45-65 years) in Sydney, and the relationship between sociodemographic factors and menopausal symptoms, and also to explore the cultural context. METHODS Two hundred and three women were interviewed about their menopausal experiences in the preceding week using the 29-item Menopause-Specific Quality of Life questionnaire. RESULTS The mean age of menopause for Indian women was found to be earlier than in other groups in the published literature, at 48.21 years. While there were higher scores for physical symptoms than for other symptoms, and there were significant differences between perimenopausal women and the others, it was found that the prevalence of classical menopausal symptoms was lower in Indian women than that found in Caucasians. However, physical and several psychological symptoms were found to be more prevalent than the usual vasomotor symptoms. Unemployed women and women with a tertiary level of education were found to experience a significantly higher score for all symptoms in our sample. CONCLUSIONS Lower scores of menopause symptoms indicate that Indian women have fewer complaints of symptoms and a positive attitude towards menopause. Somatic symptoms are multifactorial in nature and could be because of health problems associated with ageing, midlife crises and cultural influences. Further detailed studies could examine the important relationship between cultural lifestyle factors and climacteric symptoms.

Abstract
The efficacy of 5 years of adjuvant tamoxifen in preventing disease recurrence in patients with breast cancer has been well established. Once patients have completed tamoxifen therapy, however, recurrence risk remains but treatment options are limited. Aromatase inhibitors such as letrozole are emerging as potential alternatives to tamoxifen therapy and as an option after tamoxifen. The pioneering MA-17 trial was designed to evaluate the efficacy and safety of letrozole in the extended adjuvant setting in postmenopausal women who remained disease-free after about 5 years of tamoxifen. The trial was unblinded at first interim analysis after letrozole proved more effective than placebo in improving disease-free survival. As such, the optimal duration of extended adjuvant letrozole was left in question. However, recent results from cohort analysis in MA-17 have shown an ongoing and increasing benefit of letrozole for up to 4 years after tamoxifen, suggesting that longer periods of extended adjuvant letrozole are safe and clinically beneficial.

Abstract
OBJECTIVE The aim of this study was to investigate the role of menopausal transition and menopausal symptoms in relation to quality of life in a cohort of middle-aged women in Kinmen. DESIGN A total of 734 premenopausal women participated in the baseline study, and 579 women (78.9%) completed a follow-up 2 years later. Quality of life was assessed by the Medical Outcomes Study Short Form-36. Participating women were asked for demographic data, about vasomotor symptoms, and to complete the Medical Outcomes Study Short Form-36 and the Hospital Anxiety and Depression Scale. RESULTS There was no demographic difference between women who remained premenopausal and those who entered perimenopause except for age. Vitality deteriorated no matter whether the women stayed in premenopause or entered perimenopause. In multivariate analysis, only vasomotor symptoms had an adverse influence on role limitation of emotion after adjusting for age, education, menopausal status, baseline cognitive score, and Hospital Anxiety and Depression Scale score. The menopausal transition did not influence the eight domains of the Short Form-36 in the multivariate regression model. CONCLUSION This longitudinal study found no significant effect of menopausal transition on quality of life among Taiwanese women. The decline in the role limitations due to emotional problems was related to vasomotor symptoms.

Abstract
OBJECTIVE Criteria for staging the menopausal transition are not established. This article evaluates five bleeding criteria for defining early transition and provides empirically based guidance regarding optimal criteria. DESIGN/SETTING Prospective menstrual calendar data from four population-based cohorts: TREMIN, Melbourne Women's Midlife Health Project (MWMHP), Seattle Midlife Women's Health Study (SMWHS), and Study of Women's Health Across the Nation (SWAN) with annual serum FSH from MWMHP and SWAN. PARTICIPANTS 735 TREMIN, 279 SMWHS, 216 MWMHP, and 2270 SWAN women aged 35-57 at baseline who maintained menstrual calendars. MAIN OUTCOME MEASURE(S) Age at and time to menopause for: standard deviation >6 and >8 days, persistent difference in consecutive segments >6 days, irregularity, and >or=45 day segment. Serum FSH concentration. RESULT(S) Most women experienced each of the bleeding criteria. Except for a persistent >6 day difference that occurs earlier, the criteria occur at a similar age and at approximately the same age as late transition in a large proportion of women. FSH was associated with all proposed markers. CONCLUSION(S) The early transition may be best described by ovarian activity consistent with the persistent >6 day difference, but further study is needed, as other proposed criterion are consistent with later menstrual changes.

Abstract
The menopause, defined as the permanent cessation of menstruation resulting from the loss of ovarian follicular activity, marks the end of natural female reproductive life. It is preceded by a period of menstrual cycle irregularity, the menopausal transition, which usually begins in the mid-40s and is conventionally divided into early and late phases. The endocrine changes, which underlie the transition, are predominantly the consequence of a marked decline in ovarian follicle numbers. The most significant changes include a decrease in early cycle inhibin B and in anti-Mullerian hormone (AMH) levels. The decline in inhibin B results in an increase in FSH, which appears to be an important factor in the maintenance of estradiol (E2) concentrations until late in reproductive life. In the post-menopause, FSH levels are markedly raised, E2 levels are low, whereas inhibin B and AMH are undetectable. The menopausal transition is a time of marked hormonal instability. The Melbourne Women's Midlife Health Project has been an extremely productive study in which it has been possible to describe longitudinal changes in hormone levels throughout the menopause transition and to separate the effects of hormone change from the effects of ageing on a number of endpoints. This review provides the background for an accompanying manuscript in which a novel approach to modelling the hormonal changes during the transition is described.

Abstract
Changes in FSH and estradiol (E2) across the menopausal transition are clearly not linear. The present study utilizes data from 204 women who completed the 13-year prospective Melbourne Women's Midlife Health Project. E2, FSH, symptoms, self-rated health, mood, sexual function and coronary heart disease (CHD) risk were measured longitudinally. We presumed an s-shaped curve for each hormone and estimated five parameters for each hormone curve for each woman: baseline, final value, range, slope at inflexion point and age at inflexion point. These parameters were found to adequately estimate the curve for each hormone. The median age of transition observed for E2 occurs >1 year later than the median age of transition observed for FSH. FSH parameters did not affect any of the health outcomes analysed. Hot flushes, night sweats, sleeping problems, vaginal dryness and to a lesser extent self-rated health were highly significantly associated with E2 range and slope. Sexual response and CHD risk were highly significantly associated with final E2 level (post-menopausally). These findings have clinical relevance in identifying which symptoms will be triggered by steep transitions of E2 such as sudden withdrawal and which health parameters may require a maintenance level of E2.

Abstract
OBJECTIVE Many studies have evaluated the relationships between ethnicity and culture, prevalence of menopausal symptoms, and attitudes toward them, but few have assessed menopausal symptoms across cultures world-wide. This paper aims to systematically review the prevalence of hot flushes and night sweats, two prevalent symptoms of menopause, across the menopausal stages in different cultures and considers potential explanations for differences in prevalence rates. DESIGN Sixty-six papers formed the basis for this review. Studies were organized by geographic region, and results are presented for North America, Europe, East Asia, Southeast Asia, Australia, Latin America, South Asia, Middle East, and Africa. Studies were included if they provided quantitative information on the occurrence of hot flushes. This report focuses on hot flushes and night sweats, the most common menopausal symptoms reported in epidemiologic studies. RESULTS Studies reviewed indicate that vasomotor symptoms are highly prevalent in most societies. The prevalence of these symptoms varies widely and may be influenced by a range of factors, including climate, diet, lifestyle, women's roles, and attitudes regarding the end of reproductive life and aging. Patterns in hot flush prevalence were apparent for menopausal stages and, to a lesser degree, for regional variation. CONCLUSIONS Caregivers should recognize that variations exist and ask patients specific questions about symptoms and their impact on usual functioning.

Abstract
OBJECTIVE The objective of this study was to investigate hormonal and other factors associated with mammographic density during the menopausal transition and in postmenopause. DESIGN Mammograms were obtained from 252 participants in the Melbourne Women's Midlife Health Project-a longitudinal population-based study that included annual interviews, blood collection, and physical measurements; 869 original films of the right craniocaudal view were digitized. Total area of the breast and the area of dense tissue were measured, and the percentage of mammographically dense tissue (PMD) was calculated. Data were analyzed using time-series regression models. RESULTS Of the 252 women, 87% had more than one mammogram, and the mean age was 56.0 (SD 3.6) years (range 45-67); 129 women who had never used hormone therapy were included in the analyses. The mean nondense breast tissue area increased through the menopausal transition (P for trend=0.01), there was no significant trend in the mean dense breast tissue area, and mean PMD decreased (P for trend=0.004). Multivariate analysis showed that increasing age (P<0.005) and body mass index (BMI) (P<0.05), having had children (P<0.05), and higher than average free testosterone levels (P<0.05) (or lower than average sex hormone-binding globulin levels) were associated with increased area of nondense tissue. Increasing age (P<0.05) and BMI (P<0.05) were associated with decreased PMD. There was a tendency for higher than average free testosterone levels (P<0.07) and having had children (P=0.07) to be associated with lower PMD. After controlling for age, there were no significant associations with the area of dense tissue. CONCLUSIONS This longitudinal observational study has shown that after controlling for age, there was no apparent effect of menopausal change on the area of dense breast tissue. Aging and increasing BMI through the menopausal transition were associated with increased nondense breast tissue and explain a small, but statistically significant, portion of the variation in PMD tissue.

Abstract
OBJECTIVE To examine the relationship between reproductive hormonal dynamics and sexual dysfunction assessed in a cohort of women approaching menopause. METHODS Women in the Penn Ovarian Aging Study were assessed at yearly intervals for 3 years with early follicular hormone measurements (estradiol, follicle-stimulating hormone, luteinizing hormone [LH], sex hormone binding globulin, dehyroepiandrosterone sulfate [DHEAS], total testosterone), anthropometric measures, and extensive questionnaires including the Female Sexual Function Index. Univariable analyses were performed to determine the association between hormones, menopausal status, and sexual dysfunction. Multivariable linear and logistic regression models were created to examine the influence of hormones on sexual function adjusting for the effect of potential confounders. RESULTS The final multivariable model indicated that sexual dysfunction increased with advanced menopausal status, with postmenopausal women being 2.3 times as likely to experience sexual dysfunction compared with premenopausal women (odds ratio 2.3, 95% confidence interval [CI] 1.3-4.1). Low DHEAS serum concentrations were associated with decreased sexual function (odds ratio 1.59, 95% CI 1.19-2.14). Additional risk factors associated with sexual dysfunction included absence of a sexual partner (11.2, 95% CI 6.9-18.1), high anxiety (3.8, 95% CI 1.6-9.2), and children under the age of 18 living at home (1.6, 95% CI 1.1-5.5). Lubrication, orgasm, and pain were specific aspects of sexuality negatively affected by menopause. CONCLUSION This study confirms the observation that sexual dysfunction increases over the menopausal transition. Several factors associated with sexual dysfunction include low DHEAS, absence of a sexual partner, anxiety, and children under the age of 18 living at home. LEVEL OF EVIDENCE II.

Abstract
AIM To evaluate the effects of different types, regimens and administration routes of hormone replacement therapy (HRT) on body fat composition indices in postmenopausal women at increased risk of anthropometry-related cardiovascular disease (CVD). METHODS Fifty-nine postmenopausal women (aged 41-57 years, mean +/- standard deviation: 49.9 +/- 3.8 years) with body mass index (BMI) > or =25 kg/m(2) participated in this 6-month, prospective, randomized single-blind study. Subjects were assigned into three groups and received transdermal estradiol (E2)/norethisterone acetate (NETA) (50 microg E2 daily for 14 days followed by 50 microg E2/0.25 microg NETA daily for 14 days; transdermal group, n = 19), transdermal continuous E2/oral medroxyprogesterone acetate (MPA) (50 microg E2/5 mg MPA daily; transdermal/oral group, n = 19) or oral continuous E2/NETA (1 mg E2/0.5 mg NETA daily; oral group, n = 21). Anthropometric indices (body weight, height, and hip and waist circumferences) were measured, and BMI and waist-to-hip ratio (WHR) were calculated, before and after treatment. Also, the thickness of subcutaneous abdominal fat was measured by ultrasound. Depending on waist circumference (WC), the subjects were divided into two risk groups: increased-risk group with WC <88 cm (n = 32) and high-risk group with WC > or =88 cm (n = 27). Also, the effects of HRT were evaluated separately in subjects with median subcutaneous fat of <33 mm (n = 29) and those with median subcutaneous fat of > or =33 mm (n = 30). RESULTS Overall, all three types of HRT caused a significant decrease in both WC and subcutaneous fat (p < 0.001), and also in WHR (p < 0.05). There was no significant difference in baseline (p > 0.05) and final values (p > 0.05) between HRT groups. In each group, all types of HRT significantly decreased WC and subcutaneous fat (transdermal group: p < 0.001 and p < 0.05; transdermal/oral group: p < 0.001 and p < 0.01; oral group: p < 0.001 and p < 0.001, respectively), while body weight, BMI and WHR changed only insignificantly (p > 0.05). In the increased-risk group, body weight increased significantly (p < 0.05) while WC and subcutaneous fat decreased significantly (p < 0.001 and p < 0.001). As for the high-risk group, there was a significant decrease in WC and subcutaneous fat (p < 0.001, p < 0.001) while the remaining parameters did not change significantly. However, BMI showed a tendency to increase in the increased-risk group, while there was a decrease in all measurements in the high-risk group. Regardless of the drugs used and baseline subcutaneous fat, WC and subcutaneous fat decreased significantly at the end of the treatment (subcutaneous fat <33 mm: p < 0.001 and p < 0.01; subcutaneous fat > or =33 mm: p < 0.001 and p < 0.001, respectively). CONCLUSIONS The three different types of HRT have comparable effects on central fat tissue in women at increased risk of anthropometry-related CVD. Indeed, the three combinations of HRT reduced fat tissue in the central part of the body. However, the overall effect of HRT was more marked in women with WC > or =88 cm and subcutaneous fat > or =33 cm. Whether HRT increases body weight depends on the body composition indices of individuals before treatment.

Abstract
OBJECTIVE Determinants of quality of life (QoL) in pre- and postmenopausal women including nonhormonal modulators of QoL in adult women are not well understood; there is an ongoing controversy about the impact of menopause on health-related QoL. We investigated the extent to which diverse mental and physical symptoms are associated with (a) menopausal status; (b) sociodemographic, psychosocial, and lifestyle factors; and (c) menopausal hormone therapy (MHT) in adult women after the German reunification in a region of the former German Democratic Republic. DESIGN The Study of Health in Pomerania is a cross-sectional, population-based survey. Computer-based structured interviews and self-administered questionnaires were used to capture QoL (Zerssen Symptom List) and sociodemographic parameters, psychosocial, and lifestyle indicators (age, socioeconomic status, abuse, social support, nutrition, body mass index, self-rated health, chronic diseases, and use of MHT) in 1,119 pre- and postmenopausal women with an intact uterus. RESULTS Analyses suggest that menopausal status was not associated with QoL. MHT was associated with physical, mental, and gastrointestinal symptoms. Age was a significant predictor for cardiopulmonary symptoms and sensory impairment. The relationship between age and both physical and mental complaints was inverse as was the relationship between age and both mood and gastrointestinal symptoms. Age, socioeconomic status, physical and sexual abuse, perceived social support, nutrition, body mass index, self-rated health, chronic diseases, and MHT modulated QoL. CONCLUSIONS Our findings do not support the hypothesis that QoL is reduced after menopause. Differences between pre- and postmenopausal women can be explained by sociodemographic, psychosocial, and lifestyle factors.

Abstract
OBJECTIVE There has been controversy about the relative effects on various health outcomes of hormonal, psychosocial, and lifestyle changes during the menopausal transition. In previous studies the risk factors for one particular health endpoint have been analyzed separately. Separate analyses do not provide an overall view of the relationships between all the variables or the relative importance of different factors. Thus, the objective of this study was to provide an overall analysis of the influence of hormonal changes during the menopausal transition on a range of health outcomes while simultaneously considering all the available predictors and all the endpoints and to test the hypothesis that prior health status predicts current health status. DESIGN This was a 9-year prospective observational study of 438 Australian-born women, who at baseline were aged 45 to 55 years and had menstruated in the prior 3 months. Interviews were conducted and fasting blood and physical measurements were performed annually. RESULTS Main outcome measures were hormone levels, sociodemographic variables, attitudes and lifestyle variables, self-rated health and well-being, bothersome symptoms, coronary heart disease risk, bone mineral density, and sexuality. Data from 336 women, 77% of the original sample, were analyzed. Statistical modeling using structural equations showed that for all health endpoints, the prior level of that variable was the most important predictor. Declining levels of estradiol during the menopausal transition affected certain health outcomes: bone mineral density, coronary heart disease risk, vasomotor symptoms, vaginal dryness, and sexual response. Well-being is negatively affected by symptoms, hassles, and stress. Exercise has beneficial effects on hot flushes, well-being, body mass index, and coronary heart disease risk. Relationship factors and mood affect sexual response. CONCLUSIONS This observational study provides a conceptual data-based framework for understanding changes in women's health during the natural menopausal transition.

Abstract
INTRODUCTION Recent research on the impact of testosterone (T) on female sexual function has yielded inconsistent results, and few studies have used physiological measures of genital arousal. AIM This study examined the effects of an acute dose of methyltestosterone (MT) on physiological (genital) and subjective sexual response in postmenopausal women. MAIN OUTCOME MEASURES Vaginal pulse amplitude (VPA) and self-reported sexual response. METHODS Randomized, double-blind, crossover, placebo-controlled trial of 5 mg MT, consisting of two separate 8-hour visits. Participants were 10 postmenopausal women without sexual dysfunction. Participants viewed both neutral and erotic video segments during five post-dose trials while their genital and subjective responses were monitored. RESULTS The Wilcoxon signed rank test indicated a significant difference in VPA between the T (M = 0.018, SD = 0.018) and placebo (M = 0.016, SD = 0.017) conditions at 4.5 hours post-dose (P = 0.03). Higher difference scores were noted for 80% of subjects during the T condition at 4.5 hours, in contrast with only 50% of subjects responding to T at the other four time points. No differences were found on VPA relative change scores or subjective sexual arousal scores. When summed across all five time points, genital and subjective measures were correlated regardless of medication condition (0.62 and 0.60 for self-reported physical and mental sexual arousal scores, respectively). CONCLUSIONS These findings in postmenopausal women combined with those of two previous investigations in premenopausal women demonstrate a probable acute-dose time delay for genital sexual effects of exogenous T with no change in self-reported sexual arousal. Further investigation is needed to determine whether acute dosing of T has a consistent and predictable impact on genital arousal that has promise for the treatment of any subgroup of women with sexual disorders.

Abstract
The menopause transition is a bio-psycho-socio-cultural process. Recent prospective studies highlight the complex ways in which lifestyle and cultural factors influence women's experience of the menopause. For the majority of well women, the menopause is a relatively neutral event, although women living in Western countries in general report more symptoms than those from non-Western cultures. Hot flushes and night sweats are the main symptoms of the menopause, and while the exact physiological causes are unknown, the role of norepinephrine is implicated in lowering the threshold for flushing. Psychological factors - including anxiety, stress, thoughts and beliefs and self-esteem - influence the experience of hot flushes, and a cognitive behavioural model is described which is compatible with a bio-psycho-socio-cultural perspective. Relaxation and cognitive behavioural approaches appear to be acceptable to women, and there is some evidence for their efficacy, but larger controlled trials are needed.

Abstract
Menopause is a physiologic transition and is assuming an increasing importance as the demographic bulge moves through this phase. The transition takes place over several years. It is characterized by depletion of the ovarian follicles, decreasing inhibin leading to increases in follicle-stimulating hormone and loss of the menstrual cycle, accompanied by decreased estradiol production and typical symptoms. The role of hormone therapy in menopause has shifted from preventive use to a limited role in symptom management, for which it remains the most effective intervention. There is good evidence from observational and randomized trials of an increased risk of breast cancer in women on estrogen plus a progestin, compared with those on estrogen alone. There are insufficient data to be able to determine if there are clinically important differences between various progestins and progesterone with respect to breast cancer risk, nor between different regimens. Even relatively short-term exposure to unopposed estrogen will increase the risk of atypical endometrial hyperplasia or cancer; women who have their uterus should be using a progestational agent. Lifestyle changes at menopause are important and effective for preventive health. Recent evidence suggests that the discordance between epidemiologic studies with respect to cardiovascular outcomes and the Women's Health Initiative randomized controlled trial (WHI RCT) data might be attributable in large part to the older age of women enrolled in the WHI.

Abstract
This study was undertaken to evaluate the effects of tibolone on abdominal subcutaneous fat, serum leptin levels (SLLs), and anthropometric indices, and to investigate potential relationships between SLLs, subcutaneous abdominal fat thickness, and anthropometric indices in postmenopausal women. In a 6-mo, prospective, randomized, double-blind, placebo-controlled study, 40 healthy postmenopausal women aged 42 to 67 y (mean: 50+/-4.7 y) were randomly assigned to 1 of 2 groups; during a 6-mo treatment period, the first group received tibolone (Livial tablet; Organon, The Netherlands; 2.5 mg/d; n=19) and the other group was given placebo (n=21). Fasting SLLs determined by enzyme-linked immunosorbent assay, subcutaneous abdominal fat thickness assessed by ultrasound, and anthropometric indices of body weight, body mass index, waist and hip circumference, and waist-to-hip ratio (WHR) were recorded at the beginning and the end of the study. Statistical analyses were performed with Mann-Whitney, Wilcoxon, and Spearman tests. P values <.05 were considered significant. No significant differences between the 2 groups were reported in terms of all baseline characteristics. After 6 mo, body weight (+0.77+/-0.43 kg) and SLLs (+14.7+/-6.4 ng/mL) increased in the placebo control group, whereas waist circumference (-2.6+/-3.0 cm), hip circumference (-3.6+/-3.5 cm), and subcutaneous abdominal fat thickness (-4.3+/-4.8 cm) decreased significantly in the tibolone group (P<.05). At the end of the study, group comparisons revealed significant differences in waist and hip circumference and subcutaneous abdominal fat thickness (P<.05). At baseline, SLLs were correlated with subcutaneous abdominal fat thickness and all anthropometric indices except WHR (P<.05). Subcutaneous abdominal fat thickness was also highly correlated with all indices except WHR (P<.0001). Tibolone was found to decrease waist and hip circumference, as well as subcutaneous abdominal fat thickness. Also, tibolone appeared to attenuate weight gain and leptin increase. SLLs and subcutaneous abdominal fat thickness were positively correlated with all anthropometric indices except WHR.

Abstract
AIM To investigate the association between experience of intimate partner violence (IPV) and health outcomes measured prospectively. METHOD Eleven-year prospective study of a population-based cohort of 438 Australian-born women aged 45-55 years at baseline (in 1991). Annual face-to-face interviews measured health status and quality of life; questionnaires on intimate partner physical, emotional and sexual violence and on experiences of childhood abuse completed in year 6 of follow-up. RESULTS In year 11 of follow-up 233 women (mean age 59.9 SD 2.5 years) were interviewed of whom 62 (27%) reported experiencing physical and/or emotional and/or sexual IPV prior to the 6(th) year of follow-up. In bi-variate analysis a history of IPV was significantly associated with mental and sexual health variables and marital status at baseline and follow-up. Multivariate analysis found that at follow-up after allowing for baseline measures and other co-variates: Frequency of Sexual Activities was lower in women who had experienced IPV (p < 0.05); and negative mood was higher in women with the experience of IPV during the 12 months prior to completing the violence questionnaire (p < 0.05). CONCLUSION IPV was a significant contributor to mental and sexual health status measured prospectively in this cohort of mid-aged Australian-born women.

Abstract
OBJECTIVE A variety of results from both population and laboratory studies suggest that stress and hot flashes (HFs) are correlated and that HFs are more severe in women with lower coping abilities. The objective of this pilot study was to obtain information on the feasibility and effect of participation in a mindfulness-based stress reduction (MBSR) program on HF severity and menopause-related quality of life. DESIGN Fifteen women volunteers reporting a minimum of seven moderate to severe HFs per day at study intake attended the eight weekly MBSR classes at the University of Massachusetts Medical School. Participants were assessed for menopause-related quality of life before beginning and at the conclusion of the MBSR program. Women also kept a daily log of their HFs through the course of the 7 weeks of the MBSR program and for 4 weeks after it. RESULTS Women's scores on quality-of-life measures increased significantly, and the median reported HF severity, calculated as the weekly average of a daily HF severity score, decreased 40% over the course of the 11 weeks of the assessment period. The women were individually interviewed at the completion of their participation, and the results of the interviews were consistent with the results from daily diaries. CONCLUSIONS These results provide preliminary positive evidence of the feasibility and efficacy of MBSR in supporting women who are experiencing severe HFs, and it warrants further investigation.

Abstract
CONTEXT The current criterion for onset of late menopausal transition is amenorrhea of 90 d or more. The Stages of Reproductive Aging Workshop proposed alternative criteria based on a shorter period of amenorrhea. Empirical data comparing proposed criteria are not available. OBJECTIVE This paper evaluates the several bleeding criteria that served as the basis of these recommendations. The goal was to provide empirically based guidance regarding which bleeding criterion may be optimal for widespread application in clinical and research settings. DESIGN/SETTING The study used prospective menstrual calendar data from four community and population-based cohort studies: TREMIN, Melbourne Women's Midlife Health Project, Seattle Midlife Women's Health Study, and Study of Women's Health Across the Nation. PARTICIPANTS The study included 735 TREMIN, 279 Seattle Midlife Women's Health Study, 216 Melbourne Women's Midlife Health Project, and 2270 Study of Women's Health Across the Nation women aged 35-57 yr at baseline who contributed 10 menstrual cycles or more. MAIN OUTCOME MEASURE(S) The main measures were the frequency of and median age at occurrence and time from occurrence to final menstrual period (FMP) for four criteria: skipped segment, 10-segment running range, 60- and 90-d amenorrhea. RESULTS A skipped segment, 10-segment running range greater than 42 d and 60-d amenorrhea identify a similar time in women's reproductive lives. The latter two identify the exact same date in two thirds of women. All three criteria occur in a greater proportion of women than the 90-d criterion and are equally predictive of the FMP, although they occur 1-2 yr earlier. CONCLUSIONS These findings support the recommendation of the Stages of Reproductive Aging Workshop that 60 d of amenorrhea be used to define onset of the late menopausal transition.

Abstract
BACKGROUND Menopause is a normal milestone experienced annually by 2 million American women each year, and many women are concerned about the relation between menopause and health. Associated hormonal changes have the potential to influence neurologic disease, as do hormonal therapies prescribed for menopausal symptoms or other conditions. The objective of this article is to increase neurologists' awareness of the relation between menopause and neurologic illness. REVIEW SUMMARY This was a focused review of 4 common neurologic disorders potentially influenced by menopause or by estrogen-containing hormone therapy: stroke, epilepsy, Parkinson disease, and Alzheimer disease. Hormonal effects are germane to each illness, although clinical implications are clearer for stroke and Alzheimer disease than for epilepsy and Parkinson disease. For women with epilepsy, few clinical data directly address the role of menopause or estrogen-containing hormone therapy on seizure frequency. Relevant clinical research findings on Parkinson disease are inconsistent and provide an inadequate basis for practice guidelines. There is clinical trial evidence that hormone therapy does not reduce stroke incidence and may increase risk of ischemic stroke; hormone therapy cannot be recommended for stroke prevention. The natural menopausal transition is not characterized by objective memory loss. There is clinical trial evidence that hormone therapy should not be used for the postmenopausal woman age 65 years or older for the preservation of cognitive skills, prevention of dementia, or treatment of dementia due to Alzheimer disease. Long-term cognitive consequences of short-term hormone therapy used by younger women for menopausal symptoms remains an important area of uncertainty. CONCLUSIONS Increased awareness of hormonal influences on neurologic illness is important for the practicing neurologist.

Abstract
AIM To evaluate the effects of oral continuous 17beta-estradiol plus norethisterone acetate (E2/NETA) replacement therapy on abdominal subcutaneous fat, serum leptin level (SLL) and body composition in postmenopausal women. MATERIALS AND METHODS A 6-month, prospective, randomized, double-blind and placebo-controlled study was conducted. Forty-three healthy naturally postmenopausal women aged 43-65 years were randomly assigned to receive E2/NETA (2 mg E2 plus 1 mg NETA, n = 22) or placebo (n = 21). Fasting SLL by enzyme-linked immunosorbent assay, subcutaneous abdominal fat thickness (STh) by ultrasound and the anthropometric indices of body weight (BW), body mass index (BMI), waist and hip circumference (WC, HC) and waist-to-hip ratio (WHR) were recorded at the beginning and the end of the study. RESULTS After 6 months of therapy, BW and SLL increased in the placebo group (p = 0.043 and 0.033, respectively). WC, HC and STh decreased significantly in the E2/NETA group (p = 0.002, 0.006 and 0.000, respectively) and they were also significantly lower in women receiving E2/NETA than in women taking placebo (p = 0.000, 0.034 and 0.000, respectively). At baseline, SLL and STh were positively correlated with all anthropometric indices except WHR. CONCLUSION Oral continuous combined regimen of E2/NETA significantly reduced central fat accumulation as assessed by WC and STh, and attenuated the increase in SLL. The observed changes in SLL were highly and positively related to changes in STh. The oral continuous combined E2/NETA regimen appears to have protective effects on cardiovascular function and probably on metabolic diseases by its slimming effect upon WC in postmenopausal women.

Abstract
Increased prevalence of Alzheimer’s disease (AD) in women has led to an interest in the role of hormonal changes in the neurodegenerative process. In particular, research has been directed towards investigating the effect of changes in sex hormone levels following reproductive senescence. Clinical trials of hormone-replacement therapy for the prevention of AD are proving contentious, and considerably more research is necessary before the benefit of the hormone replacement strategy can be ascertained. However, evidence is now emerging to support the notion that increased gonadotropin levels may confer an increased risk of AD. Gonadotropins have been implicated in the metabolism of β-amyloid, a key protein that is central to the pathogenesis of AD. Gonadotropin reduction represents a promising new target for therapeutic intervention in AD and, potentially, dementia in general. In this review, the authors discuss the therapeutic and preventive potential of gonadotropin-reducing agents in the management of AD.

Abstract
Evaluation of: van Anders SM, Chernick AB, Chernick BA et al.: Preliminary clinical experience with androgen administration for pre- and postmenopausal women with hypoactive sexual desire. J. Sex Marital Ther. 31, 173-185 (2005). There has been significant debate about the potential role of androgens in the treatment of hypoactive sexual desire in women. In this study, pre- and postmenopausal women with hypoactive sexual desire were age-matched with women without such complaints (n = 33). The treatment group received 100 mg of testosterone cypionate intramuscularly once a month for 3 months. Measures of salivary testosterone indicated no difference between groups at baseline, with an increase in testosterone levels in the hypoactive sexual desire group post-treatment. While significant differences existed between the two groups at baseline in scores on the Sexual Desire Inventory, the treated women demonstrated a significant increase in sexual desire post-treatment, with no difference in Sexual Desire Inventory scores at study end point. This study suggests that supplemental testosterone may improve sexual desire in women with hypoactive sexual desire without hypoandrogenism.
