Relative contributions of oligomenorrhea and hyperandrogenemia to the risk of metabolic syndrome in midlife women

Management of polycystic ovary syndrome must include assessment and treatment of mental health symptoms

Polycystic ovary syndrome (PCOS) is an endocrine disorder with reproductive and metabolic manifestations affecting millions of women worldwide. The health risks associated with PCOS, however, go beyond physical health. Over the past decade, data have emerged demonstrating a high risk of concurrent mental health conditions, specifically depression and anxiety, but extending into other aspects of psychological health, including body image distress, eating disorders, and sexual dysfunction. International surveys suggest physician knowledge about the mental health associations with PCOS is poor and that patients are often dissatisfied regarding counseling-related psychological issues. We performed a review of mental health comorbidities in individuals with PCOS, including depression, anxiety, body image distress, eating disorders, psychosexual dysfunction, and decreased quality of life, as well as evaluated the impact of common PCOS treatments on these conditions. Most meta-analyses in reproductive age women demonstrate increased risks of these conditions, although data are more limited in adolescents and older adults. In addition, the impact of PCOS treatments on these conditions as well as data on first-line treatments in the PCOS population is limited. All providers involved in the multidimensional care of individuals with PCOS should be aware of these mental health risks to provide appropriate screening, counseling and referral options. Future studies should be designed to evaluate targeted treatment for individuals with PCOS.

PCOS during the menopausal transition and after menopause: a systematic review and meta-analysis

BACKGROUND

Current knowledge about the consequences of PCOS during the late reproductive years and after menopause is limited.

OBJECTIVE AND RATIONALE

We performed a systematic review and meta-analysis of data on the pathophysiology, clinical manifestations, diagnosis, prognosis, and treatment of women ≥45 years of age-peri- or postmenopausal-with PCOS.

SEARCH METHODS

Studies published up to 15 April 2023, identified by Entrez-PubMed, EMBASE, and Scopus online facilities, were considered. We included cross-sectional or prospective studies that reported data from peri- or postmenopausal patients with PCOS and control women with a mean age ≥45 years. Three independent researchers performed data extraction. Meta-analyses of quantitative data used random-effects models because of the heterogeneity derived from differences in study design and criteria used to define PCOS, among other confounding factors. Sensitivity analyses restricted the meta-analyses to population-based studies, to studies including only patients diagnosed using the most widely accepted definitions of PCOS, only menopausal women or only women not submitted to ovarian surgery, and studies in which patients and controls presented with similar indexes of weight excess. Quality of evidence was assessed using the GRADE system.

OUTCOMES

The initial search identified 1400 articles, and another six were included from the reference lists of included articles; 476 duplicates were deleted. We excluded 868 articles for different reasons, leaving 37 valid studies for the qualitative synthesis, of which 28 studies-published in 41 articles-were considered for the quantitative synthesis and meta-analyses. Another nine studies were included only in the qualitative analyses. Compared with controls, peri- and postmenopausal patients with PCOS presented increased circulating total testosterone (standardized mean difference, SMD 0.78 (0.35, 1.22)), free androgen index (SMD 1.29 (0.89, 1.68)), and androstenedione (SMD 0.58 (0.23, 0.94)), whereas their sex hormone-binding globulin was reduced (SMD -0.60 (-0.76, -0.44)). Women with PCOS showed increased BMI (SMD 0.57 (0.32, 0.75)), waist circumference (SMD 0.64 (0.42, 0.86)), and waist-to-hip ratio (SMD 0.38 (0.14, 0.61)) together with increased homeostasis model assessment of insulin resistance (SMD 0.56 (0.27, 0.84)), fasting insulin (SMD 0.61 (0.38, 0.83)), fasting glucose (SMD 0.48 (0.29, 0.68)), and odds ratios (OR, 95% CI) for diabetes (OR 3.01 (1.91, 4.73)) compared to controls. Women with PCOS versus controls showed decreased HDL concentrations (SMD -0.32 (-0.46, -0.19)) and increased triglycerides (SMD 0.31 (0.16, 0.46)), even though total cholesterol and LDL concentrations, as well as the OR for dyslipidaemia, were similar to those of controls. The OR for having hypertension was increased in women with PCOS compared with controls (OR 1.79 (1.36, 2.36)). Albeit myocardial infarction (OR 2.51 (1.08, 5.81)) and stroke (OR 1.75 (1.03, 2.99)) were more prevalent in women with PCOS than controls, the ORs for cardiovascular disease as a whole, coronary artery disease as a whole, breast cancer and age at menopause, were similar in patients and controls. When restricting meta-analysis to studies in which women with PCOS and controls had a similar mean BMI, the only difference that retained statistical significance was a decrease in HDL-cholesterol concentration in the former and, in the two studies in which postmenopausal women with PCOS and controls had similar BMI, patients presented with increased serum androgen concentrations, suggesting that hyperandrogenism persists after menopause, regardless of obesity.

WIDER IMPLICATIONS

Hyperandrogenism appeared to persist during the late-reproductive years and after menopause in women with PCOS. Most cardiometabolic comorbidities were driven by the frequent coexistence of weight excess and PCOS, highlighting the importance of targeting obesity in this population. However, the significant heterogeneity among included studies, and the overall low quality of the evidence gathered here, precludes reaching definite conclusions on the issue. Hence, guidelines derived from adequately powered prospective studies are definitely needed for appropriate management of these women.

Change in Androgenic Status and Cardiometabolic Profile of Middle-Aged Women with Polycystic Ovary Syndrome

Understanding the cardiovascular disease (CVD) risk for women with polycystic ovary syndrome (PCOS) at reproductive age is crucial. To investigate this, we compared the cardiometabolic profiles of different PCOS groups over a median interval of 15.8 years. The study focused on three groups: (1) women with PCOS who were hyperandrogenic at both initial and follow-up screening (HA-HA), (2) those who transitioned from hyperandrogenic to normoandrogenic (HA-NA), and (3) those who remained normoandrogenic (NA-NA). At initial and follow-up screenings, both HA-HA and HA-NA groups showed higher body mass indexes compared to the NA-NA group. Additionally, at follow-up, the HA-HA and HA-NA groups exhibited higher blood pressure, a higher prevalence of hypertension, elevated serum triglycerides and insulin levels, and lower levels of HDL cholesterol compared to the NA-NA group. Even after adjusting for BMI, significant differences persisted in HDL cholesterol levels and hypertension prevalence among the groups (HA-HA: 53.8%, HA-NA: 53.1%, NA-NA: 14.3%, p < 0.01). However, calcium scores and the prevalence of coronary plaques on CT scans were similar across all groups. In conclusion, women with PCOS and hyperandrogenism during their reproductive years exhibited an unfavorable cardiometabolic profile during their post-reproductive years, even if they changed to a normoandrogenic status.

Association between serum total testosterone levels and metabolic syndrome among adult women in the United States, NHANES 2011-2016

OBJECTIVE

To investigate the association between serum total testosterone (TT) levels and metabolic syndrome (MetS) or its components among adult women.

METHODS

2,678 women from NHANES 2011-2016 were included in this cross-sectional study. MetS was determined according to the National Cholesterol Education Program Adult Treatment Panel III guidelines. The association between serum TT levels and MetS was evaluated by two logistics regression models and the adjusted restricted cubic spline (RCS). Stratified analysis and sensitive analysis were also conducted.

RESULTS

Continuous TT levels were negatively associated with the occurrence of MetS, and the ORs associated with per SD increase in ln TT were 0.70 (95%CI: 0.58-0.85) in 2011-2014 and 0.56 (95%CI: 0.39-0.79) in 2015-2016 in Model A. High TT group were less likely to have MetS (OR=0.60, 95%CI: 0.45-0.80 in 2011-2014 and OR=0.50, 95%CI: 0.32-0.78 in 2015-2016) when compared to the low TT group. When TT levels were divided into quartiles, TT levels were negatively correlated with the incidence of MetS (p for trend < 0.001). Similar trend was observed in Model B. Multivariate-adjusted logistic regression with RCS exhibited that TT had a L-shaped dose-response association with MetS or its components. Interaction analyses revealed that women who were less than 50 years old (OR=0.37, 95%CI: 0.22, 0.63), with depression (OR=0.50, 95%CI: 0.29, 0.87) or being smokers (OR=0.37, 95%CI: 0.23, 0.54) showed lower ORs than those who were over 50 years old (OR=0.66, 95%CI: 0.40, 1.09), without depression (OR=0.59, 95%CI: 0.41, 0.85) or non-smokers (OR=0.59, 95%CI: 0.39, 0.89) when measure the association between ln TT and the occurrence of MetS.

CONCLUSIONS

Our study indicated that TT levels are negatively correlated with the occurrence of MetS, with interaction effects of age, smoke behaviors, and depressive status.

The impact of ageing and menopause in women with polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common hormonal, metabolic and reproductive disorder. Women with PCOS at reproductive age have increased risk and prevalence of prediabetes and diabetes and have multiple risk factors for cardiometabolic disease and other comorbidities such as obstructive sleep apnoea, endometrial cancer and mood disorders, which contribute to the overall health burden of the syndrome. However, little is known about the impact of PCOS on long-term health in ageing women. In this review, we aimed to give an updated overview regarding the long-term health outcomes of PCOS and their clinical implications in peri- and postmenopause. The PCOS phenotype ameliorates with ageing and limited available data suggest that there is no further deterioration in cardiometabolic profile in women with PCOS after menopause. Accordingly, the risk of cardiovascular disease in ageing women with PCOS seems to be no different from those without PCOS and lower than previously anticipated based on their risk during reproductive years. Regarding other comorbidities including sleep apnoea, mood disorders and endometrial cancer, it is difficult to determine the true risk in older women with PCOS due to the confounding factors and lack of long-term cohort studies. Large, prospective studies on community-based and well-phenotyped PCOS cohorts with extended follow-up into late menopause are needed to confirm these findings.

Cardiometabolic biomarkers in women with polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. Apart from the reproductive problems, PCOS is also associated with metabolic disturbances, and therefore, it also affects adolescents and postmenopausal women with PCOS as well as their offspring and other first-degree relatives. Adolescents with PCOS show unfavorable cardiometabolic biomarkers more often than controls, such as overweight/obesity and hyperandrogenism, and studies also suggest an unfavorable lipid profile. During reproductive age, women with PCOS develop additional cardiometabolic biomarkers, such as hypertension, insulin resistance, and metabolic syndrome. Growing evidence also supports the important role of inflammatory cytokines in cardiovascular health in these women. During menopausal transition, some PCOS characteristics ameliorate, whereas other biomarkers increase, such as body mass index, insulin resistance, type 2 diabetes, and hypertension. Offspring of women with PCOS have a lower birth weight and a higher body mass index later in life than controls. In addition, fathers, mothers, and siblings of women with PCOS show unfavorable cardiometabolic biomarkers. Therefore, cardiovascular screening and follow-up of women with PCOS and their offspring and siblings are of utmost importance.

Association of severity of menstrual dysfunction with hyperinsulinemia and dysglycemia in polycystic ovary syndrome

STUDY QUESTION

Is the severity of menstrual cyclicity related to hyperinsulinemia and dysglycemia in women with hyperandrogenic polycystic ovary syndrome (PCOS)?

SUMMARY ANSWER

Hyperandrogenic PCOS women with amenorrhea, compared to those with oligomenorrhea or eumenorrhea, had a greater risk of post-challenge hyperinsulinemia, which may explain their higher prevalence of dysglycemia.

WHAT IS KNOWN ALREADY

PCOS is associated with metabolic dysregulation including insulin resistance (IR) and hyperinsulinemia, risk factors for type 2 diabetes mellitus (T2DM) and other vascular-metabolic morbidities. Although the severity of menstrual cyclicity is associated with IR in PCOS, it is unclear whether, and to what extent, it is related to hyperinsulinemia and glycemic abnormalities.

STUDY DESIGN, SIZE, DURATION

We prospectively compared the degree of menstrual cyclicity with the presence of dysglycemia (elevated 1-h plasma glucose ≥155 mg/dl; abnormal glucose tolerance [AGT], including prediabetes and T2DM; and AUC for glucose [G-AUC]) or dynamic state hyperinsulinemia (peak insulin levels either at 1 or 2 h of the oral glucose tolerance test (oGTT) and AUC for insulin [I-AUC]) in 333 hyperandrogenic PCOS women.

PARTICIPANTS/MATERIALS, SETTING, METHODS

In a tertiary care setting, hyperandrogenic PCOS participants with ovulatory eumenorrhea (Ov-Eumeno, n = 25), anovulatory eumenorrhea (Anov-Eumeno, n = 33), oligomenorrhea (Oligo, n = 150) and amenorrhea (Ameno, n = 125) underwent comprehensive phenotyping and a 2-h 75 g oGTT.

MAIN RESULTS AND THE ROLE OF CHANCE

Mean BMI was greater among Ameno women than among Oligo, Anov-Eumeno or Ov-Eumeno women. Adjusting for BMI, the Ameno group demonstrated higher mean 1- and 2-h insulin and glucose, peak insulin and I-AUC and G-AUC, and either had a higher, or tended toward having a higher, prevalence of elevated 1-h glucose level and prevalence of AGT than the Oligo, Anov-Eumeno or Ov-Eumeno groups. In logistic regression, adjusting for BMI, Ameno women were more likely to have: AGT than Oligo women (odds ratio [OR]: 2.3; 95% CI: 1.3 to 4.2); elevated 1-h glucose (OR: 10.2; CI: 1.3-79.7) than those with Ov-Eumeno; and both AGT (OR: 1.7; CI: 1.1-2.6) and elevated 1-h glucose (OR: 1.8; CI: 1.1-2.8) than those with Anov-Eumeno or Ov-Eumeno when combined. Race/ethnicity, age, waist-to-hip ratio, fasting insulin and glucose, and biochemical or clinical measures of hyperandrogenism were similar across the four menstrual categories.

LIMITATIONS, REASONS FOR CAUTION

Our study was limited by its cross-sectional nature and by studying women affected by PCOS as defined by the Androgen Excess & PCOS Society criteria (i.e. Rotterdam Phenotypes A, B and C) who were identified in the clinical setting. Consequently, extrapolation of the present data to other PCOS phenotypes (e.g. PCOS Phenotype D) should be made with caution.

WIDER IMPLICATIONS OF THE FINDINGS

In hyperandrogenic PCOS phenotypes, a history of amenorrhea, compared to oligomenorrhea or eumenorrhea, suggests a more severe cardiometabolic risk, including a higher degree of hyperinsulinemia and greater prevalence of glycemic abnormalities. These findings may assist in refining the treatment and screening guidelines for glycemic abnormalities in PCOS.

An overview of polycystic ovary syndrome in aging women

The manifestations of polycystic ovary syndrome (PCOS), a ubiquitous reproductive disorder, may vary significantly depending on the severity of a number of endocrine and metabolic changes. Although no diagnostic criteria are presently available for PCOS for perimenopausal and menopausal women, the condition can still be suspected in case of a previous diagnosis of the condition, a chronic history of irregular menstrual cycles and hyperandrogenism, and/or polycystic ovarian morphology during the reproductive period. PCOS is associated with long-term health risks, including obesity, diabetes, hypertension, dyslipidemia, metabolic syndrome and cardiovascular risk factors during reproductive age, especially in patients possessing classic phenotypes. The aim of this review was to outline the available data about the impact of PCOS on long-term health risks after reproductive age in patients with PCOS. Previously, it was assumed that women with PCOS would be more prone to develop cardiometabolic diseases after reproductive age but current data suggest that in accordance with the healing in the phenotypic characteristics of PCOS, no deterioration appears to occur in cardiometabolic health in these patients. While there is substantial evidence for a greater prevalence of abnormal subclinical atherosclerotic markers among younger patients with PCOS, data for older women are insufficient. However, there is also support for an increased risk of endometrial cancer in PCOS patients. Extensive prospective cohort studies in which healthy controls as well as patients with defining PCOS phenotypes are observed and monitored from the early reproductive period into the late postmenopausal period should now be performed in order to clarify morbidities and mortality in aging women with PCOS.

Exploring new treatment options for polycystic ovary syndrome: Review of a novel antidiabetic agent SGLT2 inhibitor

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age associated with long-term metabolic and cardiovascular consequences. A plethora of symptoms and their severity differentiate on an individual level, giving the syndrome numerous phenotypes. Due to menstrual cycle abnormalities, women suffer from irregular menstrual bleeding, difficulty in conception, and infertility. Furthermore, the risk of pregnancy complications such as gestational diabetes mellitus, hypertensive disorders of pregnancy, and preterm birth are higher in women with PCOS than in the general population. Often, women with PCOS have comorbidities such as dyslipidemia, obesity, glucose intolerance or diabetes type 2, non-alcoholic fatty liver disease, and metabolic syndrome, which all influence the treatment plan. Historic insulin-sensitizing agents, although good for some of the metabolic derangements, do not offer long-term cardiovascular benefits; therefore, new treatment options are of paramount importance. Sodium-glucose co-transporter-2 (SGLT-2) inhibitors, a new class of antidiabetic agents with beneficial cardiovascular, bodyweight, and antihyperglycemic effects, although not approved for the treatment of PCOS, might be an attractive therapeutic addition in the PCOS armamentarium. Namely, recent studies with SGLT-2 inhibitors showed promising improvements in anthropometric parameters and body composition in patients with PCOS. It is important to further explore the SGLT-2 inhibitors potential as an early therapeutic option because of the PCOS-related risk of metabolic, reproductive, and psychological consequences.

Infertility and the Risk of Cardiovascular Disease: Findings From the tudy of omen's Health cross the ation (SWAN)

Background

Cardiovascular disease (CVD) is the leading cause of death in women globally. In recent years, attention has turned to infertility and pregnancy-related events as potential markers for early mortality and future CVD.

Methods

The Study of Women’s Health Across the Nation (SWAN) is an ongoing longitudinal cohort study of women’s health. Women aged 42-52 years with a uterus and ≤ 1 intact ovary, a menstrual period, and no hormone medications within 3 months before enrollment were eligible. Infertility was self-reported and defined as the inability to achieve pregnancy after 12 months of trying to conceive, or use of fertility medications for > 1 month. Outcomes included development of metabolic syndrome over a 7-year follow-up, and any atherosclerotic CVD event (ie, stroke, angina, myocardial infarction) over a 10-year follow-up. Cox proportional hazards models were used to calculate hazard ratios (HRs) for metabolic syndrome and CVD events in participants with infertility, with adjustment for relevant covariates. Participants without infertility were used as the comparison group.

Results

We included 2370 participants in the analysis of metabolic syndrome risk, and 2809 participants were included in the analysis of CVD event risk. Participants with self-reported infertility did not have a higher risk of developing metabolic syndrome (HR, 0.91; 95% confidence interval, 0.71-1.15) or experiencing CVD events (HR, 0.79; 95% confidence interval, 0.52-1.21) after adjusting for relevant covariates.

Conclusions

Infertility was not associated with development of metabolic syndrome or CVD events in women; further research is required to investigate the effects of specific causes of infertility and fertility treatments on CVD outcomes.

Symptom clusters predict risk of metabolic-syndrome and diabetes in midlife: the Study of Women's Health Across the Nation

PURPOSE

Women's cardio-metabolic risk increases in midlife. Previous work relating menopause symptoms to diabetes/Metabolic Syndrome (MetS) does not consider the adverse impact of multiple concurrent physical and psychological symptoms in midlife.

METHODS

Data are from 3097 participants in the Study of Women's Health Across the Nation, a cohort of midlife women followed for over 20 years. Baseline latent symptom classes (LSC) were derived from 58 questions assessing physical, psychological and menopausal symptoms. Six identified LSCs ranged from 1 (most symptoms present at high severity) to 6 (few symptoms present at low severity). Accelerated failure time models estimated time to onset of type 2 diabetes and MetS for each LSC.

RESULTS

Women with multiple high/moderate severity symptoms had an earlier onset of diabetes (13.2%, 14.1% and 20.8% earlier onset in LSCs 1, 2, 3, respectively) and MetS (15.5%, 13.0% and 19.7% earlier onset in LSCs 1, 2, 3, respectively) than women with few/low severity symptoms.

CONCLUSIONS

Having multiple concurrent moderate to high intensity physical and psychological symptoms in midlife are associated with early onset of diabetes and MetS. Monitoring and subsequent intervention on a broad range of symptoms in midlife may significantly mitigate cardio-metabolic risk during this critical life stage.

Risk of Insulin Resistance and Metabolic Syndrome in Women with Hyperandrogenemia: A Comparison between PCOS Phenotypes and Beyond

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in premenopausal women, with a wide spectrum of possible phenotypes, symptoms and sequelae according to the current clinical definition. However, there are women who do not fulfill at least two out of the three commonly used "Rotterdam criteria" and their risk of developing type 2 diabetes or obesity later in life is not defined. Therefore, we addressed this important gap by conducting a retrospective analysis based on 750 women with and without PCOS. We compared four different PCOS phenotypes according to the Rotterdam criteria with women who exhibit only one Rotterdam criterion and with healthy controls. Hormone and metabolic differences were assessed by analysis of variance (ANOVA) as well as logistic regression analysis. We found that hyperandrogenic women have per se a higher risk of developing insulin resistance compared to phenotypes without hyperandrogenism and healthy controls. In addition, hyperandrogenemia is associated with developing insulin resistance also in women with no other Rotterdam criterion. Our study encourages further diagnostic and therapeutic approaches for PCOS phenotypes in order to account for varying risks of developing metabolic diseases. Finally, women with hyperandrogenism as the only symptom should also be screened for insulin resistance to avoid later metabolic risks.

Hyperandrogenemia is Common in Asymptomatic Women and is Associated with Increased Metabolic Risk

OBJECTIVE

Women with metabolic syndrome (MetS) have higher endogenous testosterone (T) levels than unaffected women. This study investigated whether hyperandrogenemia (HA) was a marker for increased cardiometabolic risk in reproductively normal premenopausal women.

METHODS

Reproductive hormones and metabolic parameters were assessed in 198 women with regular menses and no clinical hyperandrogenism (eumenorrheic [EM]). Hyperandrogenic EM women were compared with 110 women with NIH criteria polycystic ovary syndrome.

RESULTS

Twenty-two percent of EM women had HA. Levels of non-sex hormone-binding globulin (SHBG)-bound T were elevated in 68% of women, total T levels were elevated in 43% of women, and dehydroepiandrosterone sulfate levels were elevated in 30% of women. The prevalence of HA increased with BMI category (P = 0.01): 12% for BMI < 25 kg/m2 , 22% for BMI of 25 to 30 kg/m2 , and 31% for BMI ≥ 30 kg/m2 . MetS (adjusted odds ratio 2.9; 95% CI: 1.2-6.9) and dysglycemia risks (adjusted odds ratio 2.7; 95% CI: 1.2-5.8) were increased in hyperandrogenic EM women compared with normoandrogenic EM women, with adjustment for BMI. SHBG levels were independently associated with these metabolic end points (P < 0.001), whereas androgen levels were not. A cluster analysis confirmed that there was a discrete subset of EM women with HA and metabolic abnormalities.

CONCLUSIONS

HA is common in EM women and is associated with increased risks for MetS and dysglycemia. However, low SHBG levels rather than elevated androgen levels may be the primary predictor of this relationship with metabolic dysfunction.

Multidimensional informatic deconvolution defines gender-specific roles of hypothalamic GIT2 in aging trajectories

In most species, females live longer than males. An understanding of this female longevity advantage will likely uncover novel anti-aging therapeutic targets. Here we investigated the transcriptomic responses in the hypothalamus - a key organ for somatic aging control - to the introduction of a simple aging-related molecular perturbation, i.e. GIT2 heterozygosity. Our previous work has demonstrated that GIT2 acts as a network controller of aging. A similar number of both total (1079-female, 1006-male) and gender-unique (577-female, 527-male) transcripts were significantly altered in response to GIT2 heterozygosity in early life-stage (2 month-old) mice. Despite a similar volume of transcriptomic disruption in females and males, a considerably stronger dataset coherency and functional annotation representation was observed for females. It was also evident that female mice possessed a greater resilience to pro-aging signaling pathways compared to males. Using a highly data-dependent natural language processing informatics pipeline, we identified novel functional data clusters that were connected by a coherent group of multifunctional transcripts. From these it was clear that females prioritized metabolic activity preservation compared to males to mitigate this pro-aging perturbation. These findings were corroborated by somatic metabolism analyses of living animals, demonstrating the efficacy of our new informatics pipeline.

Association of serum androgens and coronary artery calcium scores in women

OBJECTIVE

To determine the association between serum androgens measured by high-resolution liquid chromatography-mass spectrometry and coronary artery calcium (CAC) scores.

DESIGN

Cross-sectional study.

SETTING

Academic institution.

PATIENT(S)

A total of 239 women, aged 40-75 years, with CAC testing and complete cardiovascular disease risk evaluation. Total T, DHEA, and androstenedione were measured using high-resolution liquid chromatography-mass spectrometry, whereas E₂ and sex hormone-binding globulin were measured using commercial assays.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Independent associations between CAC scores and sex steroids.

RESULT(S)

Overall, 164 subjects had a CAC score < 10, 48 had a CAC score between 10 and 100, and 27 had a score > 100. There were no differences in sex hormone levels between women with CAC scores > 10 vs. CAC scores ≤ 10. In multivariable models adjusting for age, body mass index, and low-density lipoprotein cholesterol, a higher T/E₂ ratio was associated with an elevated CAC score, with an unadjusted odds ratio associated with 1-SD change in log-transformed T/E₂ of 1.38 (95% confidence interval 1.01-1.89) and adjusted OR 1.02 (95% confidence interval 1.002-1.04). Total T, DHEA, androstenedione, sex hormone-binding globulin, and E₂ levels were not associated with increased CAC.

CONCLUSION(S)

In the general population, there are mixed reports regarding the relationship between serum androgens and risk factors for cardiovascular disease, and limited information on the relationship between androgens and subclinical atherosclerosis. Our study shows that increased androgens relative to estrogens may have a weak but independent association with subclinical atherosclerosis, as measured by CAC scores.

Age at Onset of Metabolic Syndrome Among Women With and Without Polycystic Ovary Syndrome-Like Status

CONTEXT

Women with polycystic ovary syndrome (PCOS) have a higher prevalence of metabolic syndrome (MetS), but whether they develop MetS earlier than women without PCOS is unknown. Understanding the impact of PCOS on the timing of MetS onset is important for screening and clinical care in this population.

DESIGN

Women with PCOS-like status (PCOSp) were identified from participants of the Michigan Bone Health and Metabolism Study based upon history of irregular menstrual cycles, high free-androgen index, and high levels of antimüllerian hormone. MetS was defined according to the Adult Treatment Panel III criteria. Age at MetS onset was compared between women with and without PCOSp using an accelerated failure time model adjusted for baseline education, lifestyle factors, and midlife body weight.

RESULTS

Among the 496 women in the analysis, 11.7% (n = 58) were determined to have PCOSp. Over a mean follow-up of 11 years, 20 women with PCOSp and 136 women without PCOSp developed MetS. After adjusting for smoking, education, and physical activity, women with PCOSp developed MetS at an age 14.4% (95% CI -22.7, -5.2) younger than women without PCOSp. The magnitude of the association was attenuated to 5.4% in models additionally adjusted for body mass index (95% CI -12.4, 2.1). Because a typical study participant without PCOSp developed MetS at 51.5 years old, 5.4% translates to almost 3 years earlier onset of MetS for a comparable woman with PCOSp.

CONCLUSIONS

Women with PCOSp develop MetS at a younger age. Earlier screening for MetS in women with PCOS may be warranted.

[Contraception for women after 40: CNGOF Contraception Guidelines]

INTRODUCTION

Choosing contraception for women over 40 can be sometimes difficult but it is crucial since fertility and pregnancy's risks still exist. It requires a thorough evaluation of the situation, in order to identify any vascular and metabolic risk factors, along with the uterine and mammary benign pathologies already diagnosed.

OBJECTIVE

The objective of this review was to elaborate some guidelines for clinical practice regarding contraception's prescription for women over 40.

METHODS

A systematic review of the French and English existing literature was conducted. Pubmed and the Cochrane library were used to identify studies about contraception for perimenopausal women. International guidelines published by scientific societies were also reviewed (RCOG, FSRH, ESHRE, ACOG, WHO, HAS).

RESULTS

No contraceptive methods are contraindicated on the sole basis of age alone. However, because age is a risk factor for vascular and metabolic diseases, combined hormonal contraception and DMPA should not be prescribed at first intention. Copper IUD and progestin-only contraceptives (pill, implant, intrauterine device) should primarily be considered, since they offer good efficacy with lower risks.

CONCLUSIONS

Contraception for women over 40 should not be put aside. Long acting reversible contraception and progestin-only pill have to be prescribed as first-ine. Contraception is no longer needed for women over 50 who use non-hormonal contraception, after a 12 month-amenorrhea. Patients treated with combined hormonal contraception must stop using it over 50. Measuring hormonal levels while using hormonal contraception is not recommended. An hormonal-contraception-free interval must be considered, while using barrier contraception method. If an ovarian activity persists, a non-hormonal contraception or progestin-only contraception (except for DMPA) should be (re-)established.

Reproductive health, obesity, and cardiometabolic risk factors among Samoan women

OBJECTIVES

Obesity leads to deleterious effects on not only cardiovascular health but also on the reproductive health of women. We estimate the prevalence of menstrual irregularity and of polycystic ovarian syndrome (PCOS) in Samoan women, among whom obesity prevalence is extremely high. We explore the association of these reproductive health conditions with adiposity, cardiometabolic risk factors, and androgen levels.

METHODS

A cross-sectional sample of Samoan women 25-39 years of age (n = 470) from a larger population-based genome-wide association study of adiposity and cardiometabolic disease was assessed for the prevalence of oligomenorrhea/amenorrhea (OM/AM) using a self-reported questionnaire. Serum androgens and anti-Müllerian hormone levels were assayed to determine hyperandrogenemia and presence of polycystic ovaries (PCO), respectively, using criterion values. PCOS was classified using NIH guidelines of having at least two of the three conditions: menstrual irregularity, hyperandrogenism, and PCO. We contrasted socio-demographic, reproductive health, and cardiometabolic risk factors between those with and without OM/AM and similarly for PCOS.

RESULTS

The prevalence of OM/AM was 7.4% (95% CI: 5.1, 9.8), and women with OM/AM had significantly higher central adiposity. PCOS was estimated at 6.8% (95% CI: 4.5, 9.1), and those with PCOS were younger but had higher overall and central adiposity measures, higher triglycerides, and higher prevalence of insulin resistance than women without PCOS.

CONCLUSIONS

The prevalence of menstrual irregularity and PCOS are less than hypothesized given the high levels of adiposity in this population. Nevertheless, Samoan women with menstrual irregularity and other features of PCOS have significantly poorer metabolic health.

The impact of supervised weight loss and intentional weight regain on sex hormone binding globulin and testosterone in premenopausal women

What is the impact of intentional weight loss and regain on serum androgens in women? We conducted an ancillary analysis of prospectively collected samples from a randomized controlled trial. The trial involved supervised 10% weight loss (8.5 kg on average) with diet and exercise over 4-6 months followed by supervised intentional regain of 50% of the lost weight (4.6 kg on average) over 4-6 months. Participants were randomized prior to the partial weight regain component to either continuation or cessation of endurance exercise. Analytic sample included 30 obese premenopausal women (mean age of 40 ± 5.9 years, mean baseline body mass index (BMI) of 32.9 ± 4.2 kg/m(2)) with metabolic syndrome. We evaluated sex hormone binding globulin (SHBG), total testosterone (T), free androgen index (FAI), and high molecular weight adiponectin (HMWAdp). Insulin, homeostasis model assessment (HOMA), and quantitative insulin sensitivity check index (QUICKI), and visceral adipose tissue (VAT) measured in the original trial were reanalyzed for the current analytic sample. Insulin, HOMA, and QUICKI improved with weight loss and were maintained despite weight regain. Log-transformed SHBG significantly increased from baseline to weight loss, and then significantly decreased with weight regain. LogFAI and logVAT decreased similarly and increased with weight loss followed by weight regain. No changes were found in logT and LogHMWAdp. There was no significant difference in any tested parameters by exercise between the groups. SHBG showed prominent sensitivity to body mass fluctuations, as reduction with controlled intentional weight regain showed an inverse relationship to VAT and occurred despite stable HMWAdp and sustained improvements with insulin resistance. FAI showed opposite changes to SHBG, while T did not change significantly with weight. Continued exercise during weight regain did not appear to impact these findings.

Consistent ovulation may not be enough to make women healthy when approaching menopause: an update from the Study of Women's Health Across the Nation

OBJECTIVE

This study aims to test the hypothesis that consistently ovulatory premenopausal/perimenopausal women have a more favorable cardiometabolic profile than anovulatory women.

METHODS

The first four collections from the Study of Women's Health Across the Nation Daily Hormone Study (DHS) were used. DHS enrollees annually completed a daily collection of first morning voided urine for an entire menstrual cycle or up to 50 days (whichever comes first). A woman was categorized as consistently ovulatory annually (COA) if four ovulatory cycles or two to three ovulatory cycles followed by the final menstrual period (FMP) were observed. A woman was categorized as not consistently ovulatory annually (nCOA) if at least one anovulatory year was observed. Cross-sectional and longitudinal differences were compared between COA and nCOA women. Data were centered at FMP and adjusted for age and body mass index (BMI).

RESULTS

Six hundred thirty-six DHS participants (mean [SD] age, 47.3 [2.5] y; mean [SD] BMI, 27.4 [7.1] kg/m(2)) were included. Thirty-six percent of the DHS participants were COA women. On the fourth follow-up collection, COA women had lower high-density lipoprotein than nCOA women (mean [95% CI], 55.7 [54.0-57.4] vs 59.5 [57.9-61.0] mg/dL, P = 0.002, respectively), which persisted after adjustment. Among 460 women with FMP, 39% were COA women. COA women were slightly older (52.9 vs 52.0 y, P = 0.002) and had lower BMI (geometric mean, 26.1 vs 27.5 kg/m(2), P = 0.06) than nCOA women at FMP. Other cardiometabolic factors did not significantly differ by COA status through FMP.

CONCLUSIONS

Consistent ovulation across the menopausal transition does not seem to reflect superior cardiometabolic health.

A comprehensive approach in diagnosing the polycystic ovary syndrome

The polycystic ovary syndrome is the commonest hyperandrogenic and dysmetabolic disorder in women that, by definition, may present with different phenotypes, including the classic forms and those with a milder presentation. Its diagnosis is mainly based on careful clinical judgment, although it may require additional investigation by blood testing or imaging techniques in the differential diagnosis of androgen excess. This article summarizes the most important aspects of the diagnostic procedure and suggests how to apply them in clinical practice.

Irisin: a new molecular marker and target in metabolic disorder

Irisin is a newly discovered exercise-mediated myokine which regulates energy metabolism and has been the subject of much recent research. Irisin plays an important role in metabolic diseases making it a potential new target to combat obesity and its associated disorders, such as T2DM. However, the results of several recent studies investigating the effects of irisin have been controversial. The present review will introduce the discovery of irisin, the role of irisin in metabolic disorders, possible mechanisms, and unanswered questions for future research.

The association between hyperandrogenemia and the metabolic syndrome in morbidly obese women

BACKGROUND

Female abdominal obesity is associated with hyperandrogenemia (HA), but few studies have addressed the possible association between HA and metabolic syndrome (MetS) among obese women. Some studies indicate that insulin resistance may cause HA through different mechanisms. On the other hand, a bidirectional relationship between HA and insulin resistance has been suggested. Thus, we aimed to investigate if morbidly obese women with HA had higher odds of MetS and its components than those without HA (controls), independent of polycystic ovarian syndrome (PCOS) status.

METHODS

This cross-sectional study comprised 1900 consecutive treatment seeking morbidly obese women <50 years. Free testosterone index (FTI) >0.6 defined HA. Women with previously diagnosed PCOS and those with oligo- / anovulation combined with clinical or biochemical hyperandrogenism were defined as having PCOS. Multiadjusted associations between HA and MetS were assessed by logistic regression analysis.

RESULTS

Out of 1900 morbidly obese women, 1089 (57 %), 846 (45 %) and 312 (16 %) had MetS, HA and PCOS, respectively. Compared with controls (without HA), women with HA were younger (34 [1] years vs. 39 [2], p < 0.001) had a higher prevalence of MetS (62 % vs. 53 %, p < 0.001), type 2 diabetes (18 % vs. 15 %, p = 0.045), low HDL-cholesterol (65 % vs. 48 %, p < 0.001) and hypertriglyceridemia (48 % vs. 41 %, p = 0.004), but a lower prevalence of raised blood pressure (53 % vs. 59 %, p = 0.014). Multivariable analyses showed that HA was associated with increased odds of MetS (OR 1.61 [95 % CI 1.27, 2.02]), dysglycemia (1.65 [1.28, 2.11]), low HDL-cholesterol (1.58 [1.27, 1.97]), and hypertriglyceridemia (1.43 [1.15, 1.79]). After stratification for the presence of PCOS, the results remained largely unchanged in women without PCOS; MetS (1.52 [1.18, 1.96), dysglycemia (1.71 [1.30, 2.25]), low HDL-cholesterol (1.55 [1.22, 1.98]) and hypertriglyceridemia (1.36 [1.06, 1.74]).

CONCLUSION

Morbidly obese women with HA had an approximately 1.5-fold increased odds of having MetS even in the absence of PCOS. Randomized controlled clinical trials, including therapeutic strategies to lower free testosterone levels, are however necessary to explore any cause-and-effect relationship.

The polycystic ovary syndrome: a position statement from the European Society of Endocrinology

Polycystic ovary syndrome (PCOS) is the most common ovarian disorder associated with androgen excess in women, which justifies the growing interest of endocrinologists. Great efforts have been made in the last 2 decades to define the syndrome. The presence of three different definitions for the diagnosis of PCOS reflects the phenotypic heterogeneity of the syndrome. Major criteria are required for the diagnosis, which in turn identifies different phenotypes according to the combination of different criteria. In addition, the relevant impact of metabolic issues, specifically insulin resistance and obesity, on the pathogenesis of PCOS, and the susceptibility to develop earlier than expected glucose intolerance states, including type 2 diabetes, has supported the notion that these aspects should be considered when defining the PCOS phenotype and planning potential therapeutic strategies in an affected subject. This paper offers a critical endocrine and European perspective on the debate on the definition of PCOS and summarises all major aspects related to aetiological factors, including early life events, potentially involved in the development of the disorder. Diagnostic tools of PCOS are also discussed, with emphasis on the laboratory evaluation of androgens and other potential biomarkers of ovarian and metabolic dysfunctions. We have also paid specific attention to the role of obesity, sleep disorders and neuropsychological aspects of PCOS and on the relevant pathogenetic aspects of cardiovascular risk factors. In addition, we have discussed how to target treatment choices based according to the phenotype and individual patient's needs. Finally, we have suggested potential areas of translational and clinical research for the future with specific emphasis on hormonal and metabolic aspects of PCOS.

Hyperandrogenic oligomenorrhea and metabolic risks across menopausal transition

CONTEXT

Although there is evidence of metabolic risks in young women with irregular menses and androgen excess, persistence of risks after menopause is unclear.

OBJECTIVE

The objective of the study was to determine the impact of menopause on the cardiometabolic profile in women with high androgens and a history of menstrual irregularity.

METHODS

Study of Women's Health Across the Nation is a longitudinal cohort study. Data from 1929 women without metabolic syndrome (MetS) at baseline were analyzed for incidence of MetS, self-reported stroke, and myocardial infarction. Cox hazard ratios (HRs) were estimated, adjusting for age, ethnicity, body mass, smoking, menopausal status, and study site.

RESULTS

Among MetS-free women at baseline, 497 new cases were identified during 20 249 woman-years of follow-up over 12 years. Women with hyperandrogenemia (HA) and oligomenorrhea (Oligo) developed incident cases of MetS at a comparable rate compared with their counterparts: eumenorrheic, normoandrogenic women [HR 1.4 (0.9-2.2)], oligomenorrheic, normoandrogenic women [HR 1.3 (0.8-2.2)], and eumenorrheic hyperandrogenic women [HR 1.2 (0.7-1.8)]. Smoking and obesity were the strongest predictors of incident MetS. There was no significant difference in incidence of self-reported stroke or MI by HA/Oligo status.

CONCLUSIONS

Longitudinal evidence suggests that a history of androgen excess and menstrual irregularity is not associated with worsening of metabolic health after menopause. Our findings challenge the notion that a history of concurrent HA and Oligo reflects ongoing cardiometabolic risk in postmenopausal women.

Clinical update on screening, diagnosis and management of metabolic disorders and cardiovascular risk factors associated with polycystic ovary syndrome

PURPOSE OF REVIEW

Polycystic ovarian syndrome (PCOS) is the most common endocrinopathy in premenopausal women. This review discusses the screening, diagnosis and management of metabolic disorders and cardiovascular risk factors associated with PCOS, highlighting significant recent developments.

RECENT FINDINGS

PCOS is a complex genetic disorder with multiple susceptibility genes as well as environmental factors influencing the expression of various PCOS phenotypes. The first genome-wide association study of PCOS identified susceptibility loci on chromosome 2 near the luteinizing hormone receptor gene LHCGR and chromosome 9 near the obesity gene DEEND1A. Women with PCOS are affected by a variety of metabolic disorders, including insulin resistance, metabolic syndrome, type-2 diabetes, dyslipidemia and obesity. Recently, it has been established that women with PCOS have a high risk of nonalcoholic fatty liver disease. These metabolic disturbances are associated with an increased risk of cardiovascular disease (CVD). Although women with PCOS have higher rates of cardiovascular risk factors and intermediate markers of CVD, studies definitively documenting increased CVD are lacking.

SUMMARY

The high prevalence of metabolic disorders and CVD risk factors in women with PCOS highlights the need for early screening, diagnosis and treatment of these disorders to promote long-term health and possibly prevent CVD.
