RESUMO

BACKGROUND: Oestrone, predominantly made in fat, is the main circulating oestrogen and important for target tissue oestradiol production in women after menopause. The present study was undertaken to determine the genetic regulation of blood oestrone, measured with precision, in postmenopausal women and to explore associations between the identified genetic loci and endometrial cancer in a large, independent cohort. METHODS: A genome-wide association study (GWAS) was undertaken in women aged at least 70 years to identify genetic associations with blood oestrone concentrations measured by liquid chromatography and tandem mass spectrometry. The GWAS included participants from the Sex Hormones in Older Women (SHOW) study, a sub-study of the longitudinal ASPREE (ASPirin in Reducing Events in the Elderly) randomised trial. Of the 6358 women providing a biobank sample at enrolment, 4951 unrelated women of European ancestry, not taking sex hormones, anti-oestrogens, anti-androgens or systemic glucocorticoids were included in the GWAS. Single nucleotide polymorphisms (SNPs) from loci identified below the genome-wide significance threshold were then tested in an independent cohort (the UK Biobank) for association with endometrial cancer risk, using logistic regression and adjusting for age, body mass index (BMI) and the top 10 genetic principal components. FINDINGS: The median age of the 4951 women included in the GWAS was 75.9 years (range 70-94.8 years). The GWAS identified four independent SNPs associated with oestrone concentrations (p < 5 × 10-8). Among them, the effect (minor) alleles rs34670419-T, rs2846729-T and rs2414098-T were associated with lower oestrone concentrations. Carrying these effect alleles was associated with lower oestrone concentrations in a dose-dependent manner. The effect allele rs56400819-A was associated with higher oestrone concentrations. When applied to UK Biobank, carrier status for rs2414098-T associated with the CYP19A1 gene which encodes the aromatase enzyme required for oestrogen synthesis was significantly associated with lower endometrial cancer risk (adjusted odd ratio [aOR] 0.87 [95% CI 0.82-0.93]; p = 6.69 × 10-5 for women across all ages and aOR 0.89 [95% CI 0.83-0.96]; p = 0.003 for postmenopausal women). None of the models that included age, body mass index (BMI), the top 10 genetic principal components, parity and diabetes mellitus explained more than 7.6% of the variation in risk. INTERPRETATION: We have shown genetic regulation of oestrone concentrations in postmenopausal women, and that SNPs associated with oestrone were also associated with endometrial cancer risk, independent of BMI, parity and diabetes mellitus. Although the apparent contribution was modest, the biological influence of oestrone concentrations may be greater through conversion to oestradiol in endometrial tissue. FUNDING: The ASPREE trial was supported by the National Institute on Aging and the National Cancer Institute at the National Institutes of Health (Grant U01AG029824); the National Health and Medical Research Council (NHMRC) of Australia (Grant 34047, 1127060); Monash University (Australia); and the Victorian Cancer Agency (Australia). The ASPREE Healthy Ageing Biobank was funded by the CSIRO (Flagship Grant), the National Cancer Institute (Grant U01 AG029824) and Monash University.

RESUMO

OBJECTIVE AND RATIONALE: To identify and appraise current national and international clinical menopause guidance documents, and to extract and compare the recommendations of the most robust examples. DESIGN: Systematic review. DATA SOURCES: Ovid MEDLINE, EMBASE, PsycINFO and Web of Science ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Practice guidance documents for menopause published from 2015 until 20 July 2023. Quality was assessed by the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. RESULTS: Twenty-six guidance papers were identified. Of these, five clinical practice guidelines (CPGs) and one non-hormonal therapy position statement met AGREE II criteria of being at least of moderate quality. The five CPGs listed symptoms associated with the perimenopause and menopause to be vasomotor symptoms (VMS), disturbed sleep, musculoskeletal pain, decreased sexual function or desire, and mood disturbance (low mood, mood changes or depressive symptoms). Acknowledged potential long-term menopause consequences were urogenital atrophy, and increased risks of cardiovascular disease and osteoporosis. VMS and menopause-associated mood disturbance were the only consistent indications for systemic menopausal hormone therapy (MHT). Some CPGs supported MHT to prevent or treat osteoporosis, but specific guidance was lacking. None recommended MHT for cognitive symptoms or prevention of other chronic disease. Perimenopause-specific recommendations were scant. A neurokinin 3B antagonist, selective serotonin/norepinephrine (noradrenaline) reuptake inhibitors and gabapentin were recommended non-hormonal medications for VMS, and cognitive behavioural therapy and hypnosis were consistently considered as being of potential benefit. DISCUSSION: The highest quality CPGs consistently recommended MHT for VMS and menopause-associated mood disturbance, whereas clinical depression or cognitive symptoms, and cardiometabolic disease and dementia prevention were not treatment indications. Further research is needed to inform clinical recommendations for symptomatic perimenopausal women.

RESUMO

BACKGROUND: Blood concentrations of testosterone and estrone tend to increase in women aged ≥70 years, whereas concentrations of their precursor hormone dehydroepiandrosterone decline. It is unknown whether these changes influence physical function. We investigated whether concentrations of these hormones were associated with grip strength and self-reported physical function in community-dwelling older women. METHODS: A total of 9 179 Australian women, aged ≥70 years, were recruited to the ASPirin in Reducing Events in the Elderly (ASPREE) trial. Sex hormones were measured in Sex Hormones in Older Women, an ASPREE substudy, by liquid chromatography-tandem mass spectrometry in 6 358 women. The associations between hormone concentrations and physical function (handgrip strength and self-reported physical function assessed by SF-12v2 physical component summary [PCS]) were examined using multiple linear regression. RESULTS: The median age of the 5,447 participants was 74.0 (interquartile range 71.7-77.6) years. Testosterone concentrations above the lowest quartile were associated with less decline in grip strength (mean -1.39 [95% CI -1.54 to -1.24] vs -1.75 [-2.00 to -1.50] kg, p = .02), and dehydroepiandrosterone concentrations above the lowest quartile were associated with less decline in grip strength (-1.39 [-1.54 to -1.25] vs -1.82 [-2.11 to -1.55] kg, p = .007) and PCS scores (-1.49 [-1.80 to -1.17] vs -2.33 [-2.93 to -1.72], p = .02) over 4 years, compared with those in the respective lowest quartile. CONCLUSIONS: Low endogenous concentrations of testosterone and dehydroepiandrosterone were associated the greatest likelihood of physical function decline in community-based women aged ≥70 years. Further studies are warranted to determine whether testosterone and dehydroepiandrosterone therapy prevent functional decline in this at-risk group using sensitive measures of muscle strength and performance.

RESUMO

IMPORTANCE: Whether dehydroepiandrosterone (DHEA) supplementation improves cognitive performance in older women is uncertain. Nonetheless, DHEA supplements are readily available over the counter in several countries and are potentially being used to prevent cognitive decline and dementia. OBJECTIVE: This systematic review was conducted to evaluate the effect of exogenous DHEA on cognitive performance in postmenopausal women. EVIDENCE REVIEW: Ovid MEDLINE, EMBASE, PsycINFO, Web of Science Core Collection, and the Cochrane Central Register of Controlled Trials databases were searched for studies of postmenopausal women until November 30, 2022. Eligible studies were required to be randomized clinical trials, be at least single blind, have a placebo or comparator arm and published in English. Risk of bias of the included studies was assessed by the revised Cochrane risk-of-bias tool. FINDINGS: Of the 15 articles retrieved for full-text review, four met the inclusion criteria. In all studies DHEA was administered as a 50-mg oral daily dose and all were double blind with an identical placebo. Three were placebo-controlled, crossover studies and one was a parallel-group clinical trial. The only positive outcome was limited to a 4-wk cross-over study in which DHEA statistically significantly enhanced five of six tests of visual-spatial performance compared with placebo in 24 cognitively normal postmenopausal women. Improvement in cognitive performance with DHEA treatment over placebo group was not seen in any other study. Heterogeneity of design and use of multiple measures of cognitive performance was a barrier to meta-analysis and between study comparisons. The studies were limited by high risk of bias in multiple domains. CONCLUSION AND RELEVANCE: Overall, this systematic review does not support a beneficial effect of DHEA therapy on cognitive performance in postmenopausal women.

RESUMO

Menopause is the cessation of ovarian function, with loss of reproductive hormone production and irreversible loss of fertility. It is a natural part of reproductive aging. The physiology of the menopause is complex and incompletely understood. Globally, menopause occurs around the age of 49 years, with geographic and ethnic variation. The hormonal changes of the menopause transition may result in both symptoms and long-term systemic effects, predominantly adverse effects on cardiometabolic and musculoskeletal health. The most effective treatment for bothersome menopausal symptoms is evidence-based, menopausal hormone therapy (MHT), which reduces bone loss and may have cardiometabolic benefits. Evidence-based non-hormonal interventions are also available for symptom relief. Treatment should be individualized with shared decision-making. Most MHT regimens are not regulator approved for perimenopausal women. Studies that include perimenopausal women are needed to determine the efficacy and safety of treatment options. Further research is crucial to improve menopause care, along with research to guide policy and clinical practice.

RESUMO

Background: This study determined the prevalence of bothersome menstrual symptoms and their association with workability in naturally menstruating women not using hormonal contraception. Materials and Methods: A representative sample of community-dwelling Australian women aged 18-39 years selected from two large national electronic databases responded to a survey on general health. This study focuses on self-reported dysmenorrhea and menstrual bleeding and their association with workability and absenteeism in working women, assessed by the Workability Index. Results: Of 3,555 women, 1,573 (44.2% [95% CI: 42.6%-45.9%]) reported moderate to severe dysmenorrhea and 774 (21.8% [95% CI: 20.4%-23.2%]) reported heavy to very heavy bleeding. Women with dysmenorrhea were 50% more likely to report poorer work performance and twice as likely to report more days of sick leave in the past year (absenteeism) than other women. Conclusions: Despite the availability of safe and effective management options, Australian working women aged 18-39 years continue to experience bothersome dysmenorrhea and menstrual bleeding. Dysmenorrhea is associated with increased absenteeism and poorer workability. Therefore, awareness needs to be raised among women and health care providers of ways to manage dysmenorrhea and heavy bleeding and the unmet need for intervention in the community, respectively.

RESUMO

OBJECTIVE: We investigated whether low sex hormone concentrations are associated with depression in older women. STUDY DESIGN: This was a cross-sectional study of Australian women, aged at least 70 years, not taking medications modulating sex hormone levels. Associations between hormones, measured by liquid chromatography-tandem mass spectrometry, and depression were examined by logistic regression adjusted for potential confounders. MAIN OUTCOME MEASURES: The primary outcome was a Center for Epidemiologic Studies Depression score >10, designated as 'depression', with an expanded definition that included anti-depressant use as a secondary outcome. RESULTS: For the 5535 participants in the analysis, median age 74.0 years (interquartile range 71.7-77.7), depression prevalence was 5.8 % (95 % CI 5.2-6.4 %). In the adjusted models, a statistically significantly greater likelihood of depression was seen for women with testosterone and oestrone blood concentrations in quartile 1 compared with quartiles 2-4 (odds ratio 1.33, 95 % CI 1.04 to 1.70, p = 0.022; and 1.37, 95 % CI 1.06 to 1.78, p = 0.017, respectively). For the expanded definition, the odds ratios for the lowest testosterone and oestrone quartile compared with other quartiles were 1.47 (95 % CI 1.24 to 1.75, p < 0.001) and 1.31 (95 % CI 1.09 to 1.58, p < 0.001), respectively. A significant association for low DHEA was seen only for the expanded definition of depression (1.36, 95 % CI 1.13 to 1.64, p = 0.001). Receiver operating characteristic curves showed that the contribution of each sex hormone to the likelihood of depression was small. CONCLUSIONS: Amongst older women not taking medications that influence sex hormone concentrations, low testosterone and oestrone levels are associated with a greater likelihood of depression, but the effects are small. TRIAL REGISTRATION: International Standard Randomized Controlled Trial Number Register (ISRCTN83772183) and clinicaltrials.gov (NCT01038583).

RESUMO

BACKGROUND: Whereas symptomatic endometriosis may affect work performance, the impact of endometriosis in the general community is not known. AIMS: The associations between endometriosis and each of sick leave and work ability, were investigated in a large sample of non-healthcare seeking women. MATERIALS AND METHODS: This community-based, cross-sectional study recruited 6986 women, aged 18-39 years, from three eastern states of Australia between 11 November 2016 and 21 July 2017. Women were identified as having endometriosis if they had undergone a pelvic ultrasound and reported a diagnosis of endometriosis. Working women completed the Work Ability Index. RESULTS: Participants were predominantly of European ancestry (73.1%) and 46.8% were overweight or had obesity. The prevalence of endometriosis was 5.4% (95%CI 4.9-6.0%) with the highest prevalence of 7.7% (95%CI 6.5 to 9.1%) for women aged 35-39 years. Among the 4618 working women, those with endometriosis had significantly more sick days from work (33.6% reported ≥10 days vs 13.5%, overall χ2 P < 0.001). Endometriosis was associated with a greater likelihood of poor to moderate work ability, after adjusting for age, body mass index, ethnicity, relationship status, student status, insecure housing, being a carer for another person, parity, ever use of assisted reproductive technologies, and depressed mood (odds ratio 1.90, 95%CI 1.40-2.58, P < 0.001). CONCLUSIONS: This study provides new evidence that the negative impact of endometriosis on work attendance and work ability is not limited to women with prevalent symptoms and severe disease, but appears to encompass women across a broader spectrum of this condition in the community.

RESUMO

OBJECTIVE: The role of circulating sex hormones on structural brain ageing is yet to be established. This study explored whether concentrations of circulating sex hormones in older women are associated with the baseline and longitudinal changes in structural brain ageing, defined by the brain-predicted age difference (brain-PAD). DESIGN: Prospective cohort study using data from NEURO and Sex Hormones in Older Women; substudies of the ASPirin in Reducing Events in the Elderly clinical trial. PATIENTS: Community-dwelling older women (aged 70+ years). MEASUREMENTS: Oestrone, testosterone, dehydroepiandrosterone (DHEA), and sex-hormone binding globulin (SHBG) were quantified from plasma samples collected at baseline. T1-weighted magnetic resonance imaging was performed at baseline, 1 and 3 years. Brain age was derived from whole brain volume using a validated algorithm. RESULTS: The sample comprised of 207 women not taking medications known to influence sex hormone concentrations. A statistically higher baseline brain-PAD (older brain age relative to chronological age) was seen for women in the highest DHEA tertile compared with the lowest in the unadjusted analysis (p = .04). This was not significant when adjusted for chronological age, and potential confounding health and behavioural factors. Oestrone, testosterone and SHBG were not associated with brain-PAD cross-sectionally, nor were any of the examined sex hormones or SHBG associated with brain-PAD longitudinally. CONCLUSION: No strong evidence of an association between circulating sex hormones and brain-PAD. Given there is prior evidence to suggests sex hormones may be important for brain ageing, further studies of circulating sex hormones and brain health in postmenopausal women are warranted.

RESUMO

IMPORTANCE: The associations between endogenous dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEAS), and depression in older women are uncertain. However, DHEA supplements are widely available over the counter in some countries, and some people may be taking DHEA with the hope of positive mood effects. OBJECTIVE: This systematic review aimed to investigate the association between endogenous DHEA/DHEAS blood concentrations and depression/depressive symptoms in community-dwelling postmenopausal women.Evidence Review: Searches were conducted in Ovid MEDLINE, EMBASE, PsycINFO, and Web of Science databases for observational studies with at least 100 community-dwelling participants until March 9, 2022. The bibliographies of retrieved articles were manually searched. The studies published in English and meeting the inclusion criteria were included in the review. The risk of bias was assessed with the modified Hoy tool for cross-sectional designs and the Joanna Briggs Institute modified critical appraisal checklist for cohort studies. FINDINGS: Of the 30 articles retrieved for full-text review, 14 met the criteria for inclusion. Seven studies were cross-sectional, six were longitudinal, and one had both cross-sectional and longitudinal data. Five of eight cross-sectional studies found no association between DHEAS and depression, whereas three studies reported an inverse association. Similarly, most of the studies (n = 4) with longitudinal data reported no association, whereas two studies reported either an inverse association or mixed results for DHEAS and depression severity. No association between DHEA and depression was found irrespective of the study design. Heterogeneity of design was a barrier to meta-analysis and between study comparison. The majority of studies were limited by high risk of bias in at least one assessed domain. CONCLUSION AND RELEVANCE: This systematic review does not support an association between endogenous DHEA/DHEAS and depression in postmenopausal women.

RESUMO

BACKGROUND: The early onset of menopause is associated with increased risks of cardiovascular disease and osteoporosis. As a woman's circulating anti-Müllerian hormone (AMH) concentration reflects the number of follicles remaining in the ovary and declines towards the menopause, serum AMH may be of value in the early diagnosis and prediction of age at menopause. OBJECTIVE AND RATIONALE: This systematic review was undertaken to determine whether there is evidence to support the use of AMH alone, or in conjunction with other markers, to diagnose menopause, to predict menopause, or to predict and/or diagnose premature ovarian insufficiency (POI). SEARCH METHODS: A systematic literature search for publications reporting on AMH in relation to menopause or POI was conducted in PubMed®, Embase®, and the Cochrane Central Register of Controlled Trials up to 31 May 2022. Data were extracted and synthesized using the Synthesis Without Meta-analysis for diagnosis of menopause, prediction of menopause, prediction of menopause with a single/repeat measurement of AMH, validation of prediction models, short-term prediction in perimenopausal women, and diagnosis and prediction of POI. Risk-of-bias was evaluated using the Tool to Assess Risk of Bias in Cohort Studies protocol and studies at high risk of bias were excluded. OUTCOMES: A total of 3207 studies were identified, and 41, including 28 858 women, were deemed relevant and included. Of the three studies that assessed AMH for the diagnosis of menopause, one showed that undetectable AMH had equivalent diagnostic accuracy to elevated FSH (>22.3 mIU/ml). No study assessed whether AMH could be used to shorten the 12 months of amenorrhoea required for a formal diagnosis of menopause. Studies assessing AMH with the onset of menopause (27 publications [n = 23 835 women]) generally indicated that lower age-specific AMH concentrations are associated with an earlier age at menopause. However, AMH alone could not be used to predict age at menopause with precision (with estimates and CIs ranging from 2 to 12 years for women aged <40 years). The predictive value of AMH increased with age, as the interval of prediction (time to menopause) shortened. There was evidence that undetectable, or extremely low AMH, may aid early diagnosis of POI in young women with a family history of POI, and women presenting with primary or secondary amenorrhoea (11 studies [n = 4537]). WIDER IMPLICATIONS: The findings of this systematic review support the use of serum AMH to study the age of menopause in population studies. The increased sensitivity of current AMH assays provides improved accuracy for the prediction of imminent menopause, but diagnostic use for individual patients has not been rigorously examined. Prediction of age at menopause remains imprecise when it is not imminent, although the finding of very low AMH values in young women is both of clinical value in indicating an increased risk of developing POI and may facilitate timely diagnosis.

RESUMO

OBJECTIVE: The contribution of testosterone to depression in older women is uncertain. This review was conducted to investigate the association between endogenous testosterone blood concentrations and depression in postmenopausal women. METHODS: We searched Ovid MEDLINE, EMBASE, PsycINFO, and Web of Science databases for observational studies with at least 100 community-dwelling participants. The results were categorised by study design, and the reporting of total, bioavailable and free testosterone findings is narrative. RESULTS: The search strategy retrieved 28 articles for full-text review, of which eight met the criteria for inclusion; these described 6 cross-sectional and 2 longitudinal studies. Testosterone was measured by immunoassay in all of the included studies. No association was seen between total testosterone or free testosterone and depression in either the cross-sectional or the longitudinal studies. A significant association between bioavailable testosterone and incident depressive symptoms was limited to women at least 21 years postmenopause in one study. Most of the cross-sectional studies were not representative of national populations and lacked random selection. CONCLUSIONS: This systematic review does not support an association between testosterone and depression in postmenopausal women. However, as the included studies had substantial methodological limitations, studies of community-based samples, employing validated instruments for depression and precise measurement of blood testosterone, are needed to address this knowledge gap.

RESUMO

OBJECTIVE: To explore the associations between endogenous testosterone blood concentrations and muscle mass, strength and performance in community dwelling women. DESIGN, PATIENTS AND MEASUREMENTS: Online databases, including Ovid MEDLINE, EMBASE and Web of Science, were searched for observational studies, with at least 100 female participants, reporting associations between endogenous testosterone blood concentrations and muscle mass, strength and performance. The findings were synthesized in a narrative review. Heterogeneity in study design and analysis precluded a meta-analysis. RESULTS: Of the 36 articles retrieved for full-text review, 10 met the inclusion criteria. Eight studies were cross-sectional, 1 longitudinal and 1 provided both cross-sectional and longitudinal data. Testosterone was measured by liquid chromatography-tandem mass spectrometry in two studies and by immunoassay in 8. An association between total testosterone and muscle mass, strength or performance in women was not found. The studies of calculated free or bioavailable testosterone and lean muscle mass reported a positive association, but no association was reported for muscle strength or performance. Each included study was limited by a high risk of bias in at least one assessed domain. CONCLUSIONS: This review does not support an association between testosterone and muscle mass, strength or performance in women. This, together with the reported associations between free or bioavailable testosterone and muscle mass should be interpreted cautiously due to the predominant use of immunoassay and the inaccuracy of calculated variables. Additionally, biological significance of nonprotein bound testosterone has not been established. Further studies examining the relationship between precisely measured testosterone and muscle mass and function in women are required.

RESUMO

BACKGROUND: Vasomotor symptoms (hot flushes and night sweats) are experienced by more than two-thirds of women with breast cancer taking oral adjuvant endocrine therapy. Safe and effective treatments are lacking. Q-122 is a novel, non-hormonal compound that has shown promise for reducing vasomotor symptoms by modulation of oestrogen-responsive neurons in the hypothalamus. We aimed to assess the efficacy and safety of Q-122 in women with breast cancer taking oral adjuvant endocrine therapy and experiencing vasomotor symptoms. METHODS: We conducted a multicentre, randomised, double-blind, placebo-controlled, proof-of-concept, phase 2 trial at 18 sites in Australia, New Zealand, and the USA. Eligible participants were women, aged 18-70 years, taking a stable dose of tamoxifen or an aromatase inhibitor following breast cancer and experiencing at least 50 self-reported moderate to severe vasomotor symptoms per week. Participants were randomly assigned (1:1) using an interactive web response system to oral Q-122 100 mg or identical placebo, twice daily for 28 days. Randomisation was stratified by BMI (≤30 kg/m2 or >30 kg/m2) and use of any of a selective serotonin reuptake inhibitor, selective norepinephrine reuptake inhibitor, gabapentin, or pregabalin. Q-122 and placebo capsules were identical in appearance and containers identically labelled. During the double-blind treatment and analysis phases, the participants, investigators, clinical research organisation staff, and sponsor were masked to treatment allocation. The primary outcome was the difference in the mean percentage change from baseline in the Vasomotor Symptom Severity Score of moderate and severe hot flushes and night sweats (msVMS-SS) between Q-122 and placebo after 28 days of treatment. Primary analysis was by modified intention-to-treat and safety was assessed in all participants receiving at least one dose of study drug. This study is registered at ClinicalTrials.gov, NCT03518138. FINDINGS: Between Oct 24, 2018, and Sept 9, 2020, 243 patients were screened, 131 of whom were randomly assigned and received treatment (Q-122 n=65 and placebo n=66). Q-122 resulted in a significantly greater mean percentage change in msVMS-SS from baseline over 28 days of treatment compared with placebo (least squares mean: Q-122 -39% [95% CI -46 to -31] vs placebo -26% [-33 to -18]; p=0·018). Treatment-emergent adverse events were generally mild to moderate and similar between the two groups (treatment-related treatment-emergent adverse events in 11 [17%] of 65 patients in the Q-122 group vs nine [14%] of 66 in the placebo group); zero patients in the Q-122 group and two (3%) patients in the placebo group had serious adverse events. INTERPRETATION: Q-122 is an effective and well tolerated non-hormonal oral treatment for vasomotor symptoms in women taking oral adjuvant endocrine therapy after breast cancer. Our results support the conduct of larger and longer studies of Q-122, with potential use extending to postmenopausal women who require an alternative to menopausal hormone therapy.

RESUMO

Every woman who lives past midlife will experience menopause, which, by definition, is complete cessation of ovarian function. This process might occur spontaneously (natural menopause) or be iatrogenic (secondary menopause), and can be further classified as 'early' if it occurs before the age of 45 years and 'premature' if it occurs before the age of 40 years. Globally, the mean age of natural menopause is 48.8 years, with remarkably little geographic variation. A woman's age at menopause influences health outcomes in later life. Early menopause is associated with a reduced risk of breast cancer, but increased risks of premature osteoporosis, cardiovascular disease and premature death. The cardinal symptoms of menopause, and adverse health sequelae, are due to loss of ovarian oestrogen production. Consequently, menopausal hormone therapy (MHT) that includes oestrogen or an oestrogenic compound ameliorates menopausal symptoms, while preventing menopause-associated bone loss and cardiometabolic changes. Importantly, comprehensive care of postmenopausal women involves lifestyle optimization (attention to nutrition and physical activity, reducing alcohol consumption and not smoking) and treating other established chronic disease risk factors. This Review offers a commentary specifically on the contemporary use of MHT and novel pharmaceutical alternatives to manage menopausal symptoms.

RESUMO

BACKGROUND: Blood testosterone concentrations in women decline during the reproductive years and reach a nadir in the seventh decade, after which concentrations increase and are restored to those of reproductive-aged women early in the eighth decade. We aimed to establish the association between the concentration of testosterone in the blood and risk of major adverse cardiovascular events (MACE) and all-cause mortality in healthy older women. METHODS: SHOW was a prospective cohort substudy of the longitudinal randomised ASPREE trial. Eligible participants were women aged at least 70 years from Australia with unimpaired cognition, no previous MACE, and a life expectancy of at least 5 years. Participants who were receiving hormonal or steroid therapy were ineligible for inclusion. We measured serum concentrations of sex steroids with liquid chromatography-tandem mass spectrometry and of SHBG with immunoassay. We compared lower concentrations of sex hormones with higher concentrations using four quartiles. Primary endpoints were risk of MACE and all-cause mortality, the associations of which with sex steroid concentrations were assessed using Cox proportional hazards regression that included age, body-mass index, smoking status, alcohol consumption, diabetes, hypertension, dyslipidaemia, impaired renal function, and treatment allocation in the ASPREE trial (aspirin vs placebo). ASPREE is registered with ClinicalTrials.gov, NCT01038583. FINDINGS: Of the 9180 women recruited to the ASPREE trial between March 10, 2010, and Dec 31 2014, 6358 participants provided sufficient biobank samples at baseline and 5535 were included in the final analysis. Median age at entry was 74·0 years (IQR 71·7-77·7). During a median 4·4 years of follow-up (24 553 person-years), 144 (2·6%) women had a first MACE (incidence 5·9 per 1000 person-years). During a median 4·6 years of follow-up (3·8-5·6), 200 women died (7·9 per 1000 person-years). In the fully adjusted models, higher concentrations of testosterone were associated with a lower incidence of MACE (quartile 4 vs quartile 1: hazard ratio 0·57 [95% CI 0·36-0·91]; p=0·02), as were higher concentrations of DHEA (quartile 4 vs quartile 1: 0·61 [0·38-0·97]; p=0·04). For oestrone, a lower risk of MACE was seen for concentrations in quartile 2 only, compared with quartile 1 (0·55 [0·33-0·92]; p=0·02). In fully adjusted models, no association was seen between SHBG and MACE, or between any hormone or SHBG and all-cause mortality. INTERPRETATION: Blood concentrations of testosterone and DHEA above the lowest quartile in older women were associated with a reduced risk of a first-ever MACE. Given that the physiological effects of DHEA are mediated through its steroid metabolites, if the current findings were to be replicated, trials investigating testosterone therapy for the primary prevention of ischaemic cardiovascular disease events in older women would be warranted.
