Genitourinary symptoms and sexual function in women with primary ovarian insufficiency.

OBJECTIVE: There are limited studies on urogenital symptoms in women who experience menopause before the age of 40 years due to primary ovarian insufficiency (POI) or bilateral oophorectomy (surgical POI). This study aimed to compare the urogenital symptoms, including sexuality, of women with POI to those without the condition. METHODS: This cross-sectional study conducted was in seven Latin American countries, in which postmenopausal women (with POI and non-POI) were surveyed with a general questionnaire, the Menopause Rating Scale (MRS) and the six-item Female Sexual Function Index (FSFI-6). The association of premature menopause with more urogenital symptoms and lower sexual function was evaluated with logistic regression analysis. RESULTS: Women with POI experience more urogenital symptoms (MRS urogenital score: 3.54 ± 3.16 vs. 3.15 ± 2.89, p < 0.05) and have lower sexual function (total FSFI-6 score: 13.71 ± 7.55 vs. 14.77 ± 7.57 p < 0.05) than women who experience menopause at a normal age range. There were no significant differences in symptoms when comparing women based on the type of POI (idiopathic or surgical). After adjusting for covariates, our logistic regression model determined that POI is associated with more urogenital symptoms (odds ratio [OR]: 1.38, 95% confidence interval [CI] 1.06-1.80) and lower sexual function (OR: 1.67, 95% CI 1.25-2.25). CONCLUSION: POI, whether idiopathic or secondary to bilateral oophorectomy, is associated with symptoms that affect vaginal and sexual health.

Obesity and sexual health: focus on postmenopausal women.

Menopause is a cardiometabolic transition with many women experiencing weight gain and redistribution of body fat. Hormonal changes may affect also several dimensions of well-being, including sexual function, with a high rate of female sexual dysfunction (FSD), which displays a multifactorial etiology. The most important biological factors range from chronic low-grade inflammation, associated with hypertrophic adipocytes that may translate into endothelial dysfunction and compromised blood flow through the genitourinary system, to insulin resistance and other neuroendocrine mechanisms targeting the sexual response. Psychosocial factors include poor body image, mood disorders, low self-esteem and life satisfaction, as well as partner's health and quality of relationship, and social stigma. Even unhealthy lifestyle, chronic conditions and putative weight-promoting medications may play a role. The aim of the present narrative review is to update and summarize the state of the art on the link between obesity and FSD in postmenopausal women, pointing to the paucity of high-quality studies and the need for further research with validated end points to assess both biomarkers of obesity and FSD. In addition, we provide general information on the diagnosis and treatment of FSD at menopause with a focus on dietary interventions, physical activity, anti-obesity drugs and bariatric surgery.

Association of bilateral oophorectomy and menopause hormone therapy with mild cognitive impairment: the REDLINC X study.

BACKGROUND: Dementia is a major public health problem. Estrogen is a regulator of the central nervous system and its deficit could be involved in cognitive decline in older women. OBJECTIVE: This study aimed to evaluate the association of bilateral oophorectomy, menopause hormone therapy (MHT) and other factors on mild cognitive impairment (MCI). METHOD: The case-control study included 941 otherwise healthy postmenopausal women aged 60 years and over from six Latin American countries. Personal and family data were recorded and MCI was assessed using the Montreal Cognitive Assessment test (MoCA). RESULTS: Average age, years of education and body mass index were 66.1 ± 5.8 years, 12.4 ± 5.0 years and 26.0 ± 4.3 kg/m2, respectively. A total of 30.2% had undergone bilateral oophorectomy and 40.3% had used MHT. A total of 232 women (24.7%) had MCI. The prevalence of MCI was higher in women with intact ovaries and non-MHT users as compared to MHT users (29.3% vs. 11.7% [odds ratio (OR) 0.32; 95% confidence interval (CI) 0.20-0.51]). Among oophorectomized women, MCI prevalence was higher among non-MHT users as compared to MHT users (45.2% vs. 12.8% [OR 0.18; 95% CI 0.10-0.32]). Logistic regression analysis determined that the variables associated with MCI were age >65 years (OR 1.69; 95% CI 1.20-2.38), parity (having >2 children; OR 1.69; 95% CI 1.21-2.37), bilateral oophorectomy (OR 1.56; 95% CI 1.09-2.24), hypertension (OR 1.41; 95% CI 1.01-1.96), being sexually active (OR 0.56; 95% CI 0.40-0.79), education >12 years (OR 0.46; 95% CI 0.32-0.65) and MHT use (OR 0.31; 95% CI 0.21-0.46). CONCLUSION: Age, parity, bilateral oophorectomy and hypertension are independent factors associated with MCI; contrary to this, higher educational level, maintaining sexual activity and using MHT are protective factors.

Association between depressed mood and sexual function among mid-aged Paraguayan women.

BACKGROUND: Depressive symptoms may affect female mid-life sexuality, whereas sexual problems tend to aggravate depression. Despite this, data assessing this association drawn from mid-aged Paraguayan women are scarce. OBJECTIVE: This study aimed to assess the association between depressed mood and the risk of sexual dysfunction during female mid-life. METHODS: Sexually active urban-living women from Asunción, Paraguay (n = 193, aged 40-60 years) were surveyed with the 6-item Female Sexual Function Index (FSFI-6), the 10-item Center for Epidemiological Studies Depression Scale (CESD-10), and a general questionnaire containing personal and partner information. Depressed mood was defined as a total CESD-10 score of 10 or more, and an increased risk for sexual dysfunction as an FSFI-6 total score of 19 or less. The association of depressed mood and an increased risk of sexual dysfunction was evaluated with multivariable Poisson regression. RESULTS: The mean age (±standard deviation) of surveyed woman was 48.3 ± 6.0 years and 61.1% (n = 118) were perimenopausal and postmenopausal. A total of 21.8% (n = 42) had depressed mood and 28.5% (n = 55) had an increased risk of sexual dysfunction. The final adjusted regression model determined that women with depressed mood were twice as likely to have an increased risk of sexual dysfunction, compared to women with normal mood (adjusted prevalence ratio = 2.14, 95% confidence interval 1.26-3.60). On the other hand, depressed mood was associated with a mean total FSFI-6 score that was 20% lower than that observed among women with normal mood (adjusted incidence rate ratio = 0.80, 95% confidence interval 0.68-0.93). CONCLUSION: In this mid-aged Paraguayan female sample there was a significant association between depressed mood and an increased risk of sexual dysfunction.

Perimenopause, body fat, metabolism and menopausal symptoms in relation to serum markers of adiposity, inflammation and digestive metabolism.

BACKGROUND: Perimenopausal women gain weight that may alter inflammatory status, endocrine equilibrium, and the intensity of vasomotor symptoms. OBJECTIVE: To measure serum levels of markers related to adiposity, inflammation/angiogenesis and digestive metabolism and correlate them with body mass index (BMI), waist-to-hip ratio (WHR), metabolic parameters and menopausal symptoms (assessed with the 10-item Cervantes Scale [CS-10]). METHODS: Serum of perimenopausal women (n = 24), STRAW stages-2 and -1, was analyzed using the Bio-Plex 200 System technology to assess 30 proposed analytes. The MetS was defined by the American Heart Association criteria and women were divided as: normal BMI (NBMI), excessive BMI (EBMI), and EBMI with MetS (EBMI-MetS). RESULTS: Weight, BMI, abdominal circumference, WHR, systolic blood pressure, glucose and triglyceride levels were significantly higher and high-density lipoprotein cholesterol (HDL-C) was lower in EBMI-MetS women compared to NBMI ones. Insulin, C-peptide, resistin, adipsin, GIP, leptin, IL-6, FGF21 and PAI-1 levels were significantly higher and ghrelin and IGFBP-1 lower in EBMI-MetS women as compared to NBMI ones. Spearman's correlation of pooled data showed a significant positive correlation between abdominal perimeter and WHR and C-peptide, insulin, adipsin, resistin, leptin, PAI-1 and FGF21 and a negative correlation with IGFBP-1 levels. Total CS-10 scores and hot flush intensity did not differ between studied groups, yet positively correlated with anthropometric values but not with studied analytes. CONCLUSION: Perimenopausal women with EBMI and the MetS showed an altered metabolic profile, but no differences in menopausal symptoms which also did not correlate with changes in studied biomarkers.

Menopausal symptoms are associated with non-adherence to highly active antiretroviral therapy in human immunodeficiency virus-infected middle-aged women.

Objective: This study aimed to evaluate the association between the intensity of menopausal symptoms and highly active antiretroviral therapy (HAART) adherence in middle-aged women with human immunodeficiency virus (HIV) infection.Methods: In this cross-sectional study, 313 Peruvian women with HIV infection (age 40-59 years) were surveyed and classified as adherent or non-adherent to HAART based on the Antiretroviral Treatment Adherence Evaluation Questionnaire. The intensity of menopausal symptoms was assessed with the Menopause Rating Scale, and categorized as none, mild, moderate, and/or severe. Age, sexual orientation, used HAART scheme, time since HIV diagnosis, menopausal status, risk of depression, and presence of comorbidities were also assessed. Poisson generalized linear models with robust variance were performed in order to estimate crude prevalence ratios (PRs) and adjusted PRs using statistical (a1PR) and epidemiological criteria (a2PR).Results: A total of 19.9%, 32.6%, and 15.0% of all women presented mild, moderate, and severe menopausal symptoms, respectively. Overall, 70.6% women were non-adherent to HAART. The probability of non-adherence was higher in women with mild, moderate, and severe symptoms as compared to asymptomatic women in the non-adjusted model (PR: 1.79, 95% confidence interval [CI]: 1.39-2.29; PR: 1.76, 95% CI: 1.38-2.23; and PR: 2.07, 95% CI: 1.64-2.61, respectively) and the adjusted model.Conclusion: The severity of menopausal symptoms was associated with HAART non-adherence in HIV-infected middle-aged women.

Vitamin D, menopause, and aging: quo vadis?

Menopause and aging are associated with changes in circulating gonadal steroid hormones, insulin sensitivity, body composition, and also lifestyle and social coordinates. Vitamin D status influences different metabolic adjustments, aside from calcium-phosphorus and bone metabolism. The main blood marker used to measure endogenous vitamin D status is 25-hydroxyvitamin D. Aging is associated with increases in serum parathyroid hormone and alkaline phosphatase, and a decrease of serum calcium, phosphorus, and vitamin D metabolites. 25-Hydroxyvitamin D status is also influenced by the circannual rhythm of sun irradiation. Results of clinical association studies have not correlated with intervention trials, experimental studies, and/or meta-analyses regarding the role of vitamin D on different outcomes in women during their second half of life and the vitamin D supplementation dose needed to improve clinical endpoints. Discordant results have been related to the method used to measure vitamin D, the studied population (i.e., sociodemographics and ethnicity), study designs, and biases of analyses. Vitamin D supplementation with cholecalciferol or calcifediol may improve some metabolic variables and clinical outcomes in young postmenopausal and older women. Studies seem to suggest that calcifediol may have some advantages over other forms of vitamin D supplementation. Further studies are needed to define interventions with supplements and effective food fortification.

Metabolic syndrome during female midlife: what are the risks?

The metabolic syndrome (METS) is an entity diagnosed by three or more of the following factors: abdominal obesity, low high-density lipoprotein cholesterol, and high serum triglycerides, fasting glucose, and/or blood pressure levels. Abdominal obesity is the most prevalent component of the syndrome that favors insulin resistance and a proinflammatory and prothrombotic status, and the risk of developing diabetes, hypertension, and other chronic conditions. During the menopausal transition, women tend to gain weight and this has been related to an increase in the prevalence of the METS. Rates have also been linked to hormonal status (perimenopausal vs. postmenopausal), changes in lifestyle, and endocrine adjustments. Abnormal cytokine secretion subsequently produces endothelial dysfunction, which will consequently increase cardiovascular risk and related morbidity and mortality. This document will review the various risks that arise as a consequence of the METS during female midlife.

Sexual well-being after menopause: An International Menopause Society White Paper.

Sexual well-being frequently declines following the menopause transition and can be associated with significant personal and relationship distress. This distress is the hallmark of female sexual dysfunction (FSD). FSD is highly prevalent in postmenopausal women. The prevalence of sexual problems increases with age, but conversely this is associated with decreasing distress with advancing age. This pattern has been seen across multiple international populations with varied cultural norms. While the etiology of FSD is multifactorial, the physiological changes of sex hormone insufficiency and postmenopausal symptoms, such as dyspareunia, are primary factors contributing to FSD at midlife. The International Menopause Society is working to increase awareness of FSD and to provide a framework for practitioners to address sexual medicine concerns. This White Paper aims to review the process of care for female sexual well-being following menopause, from initially approaching the discussion of FSD, to identifying clinical signs and symptoms, and ultimately determining the best available biopsychosocial therapies. As with most processes of care, the first step is often the most difficult. Health-care practitioners need to broach the topic of sexuality in the clinical setting. Lack of information on, comfort with, and biases about the topic of sexuality after menopause are significant hurdles that the International Menopause Society addresses in this document. Each member of the Writing Group remains committed to continued advocacy for the validity of FSD as a diagnosis, the need for therapies for women to be both available and included in health insurance coverage, and continued therapeutic research to provide evidence-based solutions.

The effect of programmed exercise over anxiety symptoms in midlife and older women: a meta-analysis of randomized controlled trials.

We aimed to perform a systematic review and meta-analysis in order to clarify the effect of programmed exercise over mild-to-moderate anxiety symptoms (ASs) in midlife and older women. A structured search of PubMed, Medline, Web of Science, Scopus, Embase, Cochrane Library, Scielo, and the US, UK and Australian Clinical Trials databases (from inception through July 27, 2017) was performed, with no language restriction using the following terms: 'anxiety', 'anxiety symptoms', 'exercise', 'physical activity', 'menopause', and 'randomized controlled trial' (RCTs) in mid-aged and older women. We assessed RCTs that compared the effect of exercise for at least 6 weeks versus no intervention over ASs as outcome (as defined by trial authors). Exercise was classified according to duration as 'mid-term exercise intervention' (MTEI; for 12 weeks to 4 months), and 'long-term exercise intervention' (LTEI; for 6-14 months). Mean ± standard deviations of changes for ASs, as assessed with different questionnaires, were extracted to calculate Hedges' g and then used as effect size for meta-analyses. Standardized mean differences (SMDs) of ASs after intervention were pooled using a random-effects model. Ten publications were included for analysis related to 1463 midlife and older women (minimum age 54.2 ± 3.5 and maximum age 77.6 ± 5.4 years). Eight MTEIs were associated with a significant reduction of ASs (SMD = -0.42; 95% CI -0.81 to -0.02) as compared to controls. There was no reduction of ASs in seven LTEIs (SMD = -0.03; 95% CI -0.18 to 0.13). It can be concluded that MTEIs of low-to-moderate intensity seem to improve mild-moderate ASs in midlife and older women.

Does the menopausal status of female gynecologists affect their prescription of menopausal hormone therapy?

OBJECTIVE: To evaluate whether menopausal status and symptoms among female gynecologists would influence their clinical behavior related to menopausal hormone therapy (MHT). METHODS: Female gynecologists of 11 Latin American countries were requested to fill out the Menopause Rating Scale and a questionnaire containing personal information and that related to MHT use. RESULTS: A total of 818 gynecologists accepted to participate (86.4%). Overall, the mean age was 45.0 ± 10.7 years, 32.2% were postmenopausal, and 17.6% worked in an academic position; 81.8% reported that they would use MHT if they have symptoms, regardless of menopausal status. Academic gynecologists favor personal MHT use at a higher rate (p = 0.04) and have a higher MHT prescription rate as compared to non-academic ones (p = 0.0001). The same trend was observed among post- as compared to premenopausal ones (p = 0.01) and among those who had hysterectomy alone as compared to those experiencing natural menopause (p = 0.002). The presence of menopausal symptoms did not influence their MHT prescription. Current use of MHT and alternative therapy was higher among post- than premenopausal gynecologists (both, p = 0.0001) and among those who had undergone hysterectomy than those experiencing natural menopause. A 38.5% perceived breast cancer as the main risk related to MHT, and a high proportion prescribed non-hormonal drugs (86.4%) or alternative therapies (84.5%). CONCLUSION: Most female gynecologists in this survey would use MHT if menopausal symptoms were present. Postmenopausal physicians use MHT and prescribe it to their symptomatic patients at a higher rate than premenopausal physicians.

Evaluation of sexuality in a Paraguayan mid-aged female urban population using the six-item Female Sexual Function Index.

Background There are scant data related to sexuality assessed among mid-aged women from Paraguay. Objective To assess sexual function in a sample of mid-aged Paraguayan women. Methods This was a cross-sectional study in which 265 urban-living women from Asunción (Paraguay) aged 40-65 years were surveyed with the six-item version of the Female Sexual Function Index (FSFI-6) and a questionnaire containing personal and partner data. Results The median age of the sample was 48 years, 48.2% were postmenopausal (median/interquartile range age at menopause 46/13 years), 11.3% used hormone therapy, 37.0% used psychotropic drugs, 44.5% had hypertension, 7.2% diabetes, 46.1% abdominal obesity and 89.4% had a partner (n = 237). Overall, 84.1% (223/265) of surveyed women were sexually active, presenting a median total FSFI-6 score of 23.0, and 25.6% obtained a total score of 19 or less, suggestive of sexual dysfunction (lower sexual function). Upon bivariate analysis, several factors were associated with lower total FSFI-6 scores; however, multiple linear regression analysis found that lower total FSFI-6 scores (worse sexual function) were significantly correlated to the postmenopausal status and having an older partner, whereas coital frequency was positively correlated to higher scores (better sexual function). Conclusion In this pilot sample of urban-living, mid-aged Paraguayan women, as determined with the FSFI-6, lower sexual function was related to menopausal status, coital frequency and partner age. There is a need for more research in this regard in this population.

Polymorphisms of the FTO and MTHFR genes and vascular, inflammatory and metabolic marker levels in postmenopausal women.

OBJECTIVE: To determine the prevalence of three single nucleotide polymorphisms (SNPs) in postmenopausal women with and without the metabolic syndrome (METS) and to explore levels of circulating biomarkers of inflammation, vascular and metabolic dysfunction according to SNP genotypes. METHODS: DNA was extracted from the whole blood of 192 natural postmenopausal women (40 to 65 years) screened for the METS and tested for three gene SNPs related to obesity: the fat mass obesity (FTO: rs9939609) and the methylenetetrahydrofolate reductase (MTHFR: C677T and A1298C). Blood levels of angiopoietin, IL-8, sFASL, IL-6, TNF-α, sCD40L, PAI-1, u-PA, leptin, adiponectin, resistin, ghrelin, visfatin, adipsin and insulin were measured in a subgroup, with and without the METS, using multiplex technology (n = 100) and compared according to SNP genotypes. RESULTS: Genotype frequency of the three studied SNPs did not differ in relation to the presence of the METS. However, genotypes CT+TT (C677T) and AT (rs9939609) were more prevalent in women with high triglyceride levels. Pooled sub-analysis (n = 100) found that median sCD40L and visfatin levels were higher in women with genotypes AT+TT (rs9939609) as compared to AA (1178 vs. 937.0 pg/mL and 0.93 vs. 0.43 ng/mL, respectively, p < 0.05). CONCLUSION: Two SNP genotypes related to obesity were more prevalent in women with abnormal triglyceride levels and two vascular and inflammatory serum markers were higher in relation to the rs9939609 SNP.

Perinatal outcome in singleton pregnancies complicated with preeclampsia and eclampsia in Ecuador.

Preeclampsia in Ecuador is an understudied subject since available epidemiological data are scarce. The aim of this study was to describe perinatal outcomes among singleton pregnancies complicated with preeclampsia and eclampsia in a sample of low-income Ecuadorian women. Pregnant women complicated with preeclampsia (mild and severe) and eclampsia (defined according to criteria of the ACOG) delivering at the Enrique C. Sotomayor Obstetrics and Gynecology Hospital, Guayaquil, Ecuador were surveyed with a structured questionnaire containing maternal (socio-demographic) and neonatal data. Perinatal outcomes were compared according to severity of clinical presentation. A total of 163 women with preeclampsia [mild (23.9%), severe (68.7%) and eclampsia (7.4%)] were surveyed. Perinatal mortality and stillbirth rate was similar among studied groups (mild vs. severe preeclampsia/eclampsia cases). However, severe cases displayed higher rates of adverse perinatal outcomes: lower birth Apgar scores, more preterm births, and more low birth weight and small for gestational age infants. Caesarean-section rate and the number of admissions to intensive or intermediate neonatal care were higher in severe cases. A similar trend was found when analysis excluded preterm gestations. In conclusion, in this specific low-income Ecuadorian population perinatal outcome was adverse in pregnancies complicated with severe preeclampsia/eclampsia.

A multicentric study regarding the use of hormone therapy during female mid-age (REDLINC VI).

BACKGROUND: Menopausal hormone therapy (HT) has shown benefits for women; however, associated drawbacks (i.e. risks, costs, fears) have currently determined its low use. OBJECTIVE: To determine the prevalence of current HT use among mid-aged women and describe the characteristics of those who have never used, have abandoned or are currently using HT. In addition, reasons for not using HT were analyzed. METHOD: This was a cross-sectional study that analyzed a total of 6731 otherwise healthy women (45-59 years old) of 15 cities in 11 Latin American countries. Participants were requested to fill out the Menopause Rating Scale (MRS) and a questionnaire containing sociodemographic data and items regarding the menopause and HT use. RESULTS: The prevalence of current HT use was 12.5%. Oral HT (43.7%) was the most frequently used type of HT, followed by transdermal types (17.7%). The main factors related to the current use of HT included: positive perceptions regarding HT (odds ratio (OR) 11.53, 95% confidence interval (CI) 9.41-14.13), being postmenopausal (OR 3.47, 95% CI 2.75-4.36) and having a better socioeconomic level. A total of 48.8% of surveyed women had used HT in the past, but abandoned it due to symptom improvement or being unconcerned; fear of cancer or any other secondary effects were also reported but in less than 10%. Among women who had never used HT, 28% reported the lack of medical prescription as the main reason, followed by the absence of symptoms (27.8%). Among those reporting lack of prescription as the main reason for not using HT, 30.6% currently had severe menopausal symptoms (total MRS score > 16); 19.5% of women were using alternative 'natural' therapies, with 35.1% of them displaying severe menopausal symptoms as compared to a 22.5% observed among current HT users. CONCLUSION: The use of HT has not regained the rates observed a decade ago. Positive perceptions regarding HT were related to a higher use. Lack of medical prescription was the main reason for not using HT among non-users, many of whom were currently displaying severe menopausal symptoms.

Nutrition and health during mid-life: searching for solutions and meeting challenges for the aging population.

Interactions between genetic (genome) and environmental factors (epigenome) operate during a person's entire lifespan. The aging process is associated with several cellular and organic functional alterations that, at the end, cause multi-organic cell failure. Epigenetic mechanisms of aging are modifiable by appropriate preventive actions mediated by sirtuins, caloric input, diet components, adipose tissue-related inflammatory reactions, and physical activity. The Mediterranean lifestyle has been for many millennia a daily habit for people in Western civilizations living around the Mediterranean sea who worked intensively and survived with very few seasonal foods. A high adherence to the traditional Mediterranean diet is associated with low mortality (higher longevity) and reduced risk of developing chronic diseases, including cancer, the metabolic syndrome, depression and cardiovascular and neurodegenerative diseases. Reports indicate that some dietary components, such as olive oil, antioxidants, omega-3 and -6 polyunsaturated acids, polyphenols and flavonoids, mediate beneficial anti-aging effects (anti-chronic diseases and increased longevity). Equally, physical activity displays a positive effect, producing caloric consumption and regulation of adipose and pancreatic function. The predictive strength of some food patterns may be a way of developing recommendations for food and health policies. This paper will discuss several ways of improving health during mid-life, focusing on certain groups of functional foods and healthy habits which may reduce or prevent age-related chronic diseases.

Type II diabetes mellitus and menopause: a multinational study.

BACKGROUND: Type II diabetes mellitus causes metabolic changes that may lead to early menopause and worsen climacteric symptoms. OBJECTIVES: To determine the risk factors for type II diabetes mellitus and assess the impact of this disease on the age of menopause and on climacteric symptoms. METHODS: A total of 6079 women aged between 40 and 59 years from 11 Latin American countries were requested to answer the Menopause Rating Scale and Goldberg Anxiety-Depression Scale. RESULTS: The prevalence of diabetes was 6.7%. Diabetes mellitus was associated with arterial hypertension (odds ratio (OR) 4.49; 95% confidence interval (CI) 3.47-5.31), the use of psychotropic drugs (OR 1.54; 95% CI 1.22-1.94), hormonal therapy (OR 1.46; 95% CI 1.11-1.92), ≥ 50 years of age (OR 1.48; 95% CI 1.17-1.86), overweight or obese (OR 1.47; 95% CI 1.15-1.89), and waist circumference ≥ 88 cm (OR 1.32; 95% CI 1.06-1.65). Factors associated with lower risk of diabetes were the use of hormonal contraceptives (OR 0.55; 95% CI 0.35-0.87), alcohol (OR 0.73; 95% CI 0.54-0.98) and living in cities > 2500 meters above sea level (OR 0.70; 95% CI 0.53-0.91) or with high temperatures (OR 0.67; 95% CI 0.51-0.88). In turn, diabetes tripled the risk of menopause in women under 45 years of age. Diabetes did not increase the risk of deterioration of quality of life due to climacteric symptoms. CONCLUSION: Menopause does not increase the risk of type II diabetes mellitus. Diabetes is associated with early menopause in women under 45 years of age.

The International Menopause Study of Climate, Altitude, Temperature (IMS-CAT) and vasomotor symptoms.

OBJECTIVE: To examine the relationship between climate (including altitude, temperature, humidity and annual range of temperature) and experience of hot flushes and night sweats amongst Spanish-speaking mid-aged women living in five urban centers. METHODS: A total of 896 peri- and postmenopausal women from centers in Chile (Santiago de Chile), Ecuador (Guayaquil and Quito), Panama (Panama City) and Spain (Madrid) completed questionnaires eliciting information about sociodemographics, hot flushes (prevalence, frequency and problem-rating), health and lifestyle (body mass index, diet, exercise, alcohol use) and mood (Women's Health Questionnaire). RESULTS: There was a wide range of altitude and temperature in the participating centers. Of the sample, 58.5% (524/896) were currently experiencing vasomotor symptoms. Prevalence was associated with higher temperatures, while hot flushes were more frequent and problematic for women living in higher temperature and lower altitudes. Hot flush variables were not associated with seasonal variation in temperature. When health and lifestyle variables were included as covariates in regression analyses, prevalence was best predicted by age (younger), poor general health, more depressed mood and anxiety; hot flush frequency by anxiety, temperature, life satisfaction (lower), age (higher), regular strenuous exercise (more strenuous exercise more frequent), and a diet including regular hot spicy food intake. Hot flush problem-rating was best predicted by anxiety, life satisfaction, altitude (lower more problematic), any regular exercise (more exercise less problematic), and depressed mood. CONCLUSIONS: In this study of Spanish-speaking women, those living in countries with higher temperatures and lower altitudes reported more frequent and problematic hot flushes.

Understanding weight gain at menopause.

OBJECTIVE: The aim of this review was to summarize the literature regarding the impact of the menopause transition on body weight and body composition. METHODS: We conducted a search of the literature using Medline (Ovid, 1946-present) and PubMed (1966-2012) for English-language studies that included the following search terms: 'menopause', 'midlife', 'hormone therapy' or 'estrogen' combined with 'obesity', 'body weight' or 'body composition'. RESULTS: Whereas weight gain per se cannot be attributed to the menopause transition, the change in the hormonal milieu at menopause is associated with an increase in total body fat and an increase in abdominal fat. Weight excess at midlife is not only associated with a heightened risk of cardiovascular and metabolic disease, but also impacts adversely on health-related quality of life and sexual function. Animal and human studies indicate that this tendency towards central abdominal fat accumulation is ameliorated by estrogen therapy. Studies mostly indicate a reduction in overall fat mass with estrogen and estrogen-progestin therapy, improved insulin sensitivity and a lower rate of development of type 2 diabetes. CONCLUSION: The hormonal changes across the perimenopause substantially contribute to increased abdominal obesity which leads to additional physical and psychological morbidity. There is strong evidence that estrogen therapy may partly prevent this menopause-related change in body composition and the associated metabolic sequelae. However, further studies are required to identify the women most likely to gain metabolic benefit from menopausal hormone therapy in order to develop evidence-based clinical recommendations.
