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.

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.

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.

Vitamin D, sunlight and longevity.

Humans acquire vitamin D through skin photosynthesis and digestive intake. Two hydroxylations are needed to obtain the bioactive compound, the first produces 25-hydroxyvitamin D [25(OH)D], and the second 1,25-dihydroxyvitamin D [1,25(OH)2D]. There is no consensus regarding the appropriate cut-off level to define the normal serum 25(OH)D range. Experimental, epidemiological and clinical studies have related low vitamin D status with longevity. Although some results are controversial, low serum 25(OH)D levels have been linked to all-cause, cardiovascular, cancer and infectious related mortality. Throughout life span a significant proportion of human beings display insufficient (20-30 ng/mL) or deficient (<20 ng/mL) serum 25(OH)D levels. Appropriate lifestyle changes, such as regular short exposures to sunlight (15 min a day), and an adequate diet that includes vitamin D rich components, are not always easily accomplished. Studies relating to vitamin D supplementation have methodological limitations or are based on relatively low doses. Therefore, dosages used for vitamin D supplementation should be higher than those traditionally suggested. In this sense, there is an urgent need for prospective controlled studies using high daily vitamin D doses (2,000 IU or higher) including cardiovascular, cancer, infectious and other endpoints. Relationship between vitamin D and health outcomes is not linear, and there are probably various optimal vitamin D levels influencing different endpoints.

Bone mass gain during puberty and adolescence: deconstructing gender characteristics.

Primary prevention of osteoporosis must aim at increasing bone mass acquisition before late adolescence. During pubertal years both genders reach peak bone acquisition, though males develop a greater skeletal mass. This dimorphism is largely regulated by endocrine factors, with critical roles played by gonadal steroids, growth hormone and insulin growth factor-1, amongst the most important. Menstrual history is a surrogate for the adequacy of hormonal functioning, nutrition and physical activity that may be a marker of bone status and development in young women. Adequate levels of adrenal, reproductive and pituitary hormones, growth factors and leptin are needed for the initiation and maintenance of regular menstrual cycles as well as for the achievement of peak bone mass. Adequate regular exercise and body composition are also pivotal elements in maintaining normal mechanical bone stimulus during bone growth. Avoidance of carbonated soft drink consumption, or excessive alcohol and any tobacco should be considered as these may interfere reaching adequate bone mass.

Knowledge and practice of family planning and HIV-prevention behaviour among just delivered adolescents in Ecuador: the problem of adolescent pregnancies.

BACKGROUND: Adolescents constitute a high risk population for the spreading of sexually transmitted diseases, among them HIV/AIDS. Knowledge regarding reproductive issues among them is a key point in order to establish appropriate prevention programs. OBJECTIVE: Obtain information regarding the knowledge and practice related to family planning and HIV-prevention behaviour among adolescents of low income. METHODS: Adolescents aged 19 or less delivering at the Enrique C. Sotomayor Obstetrics and Gynecology Hospital, Guayaquil, Ecuador were surveyed in the immediate postpartum period with a structured questionnaire designed for the purpose. RESULTS: During the study period, 357 pregnant adolescents were surveyed. Mean age was 17.2 +/- 1.4 years, 30.8% were aged 16 or less. Demographical and obstetrical history differences were found when comparing adolescents in relation to age and educational level. A high rate of mothers had unplanned pregnancies (63.3%) or did not know what family planning was (49.6%). Despite high knowledge of what a condom or an oral contraceptive was, few had used them in the past. The most frequently known family planning methods in this series, which was age dependent, were: oral contraceptives (90.2%), condoms (84.9%), parenteral (66.7%) and intrauterine devices (63.3%). The majority knew what HIV/AIDS infection was, the most important sources of knowledge being: television, high school source, and family or relatives. A high rate of adolescents had never had an HIV test performed in the past with one prior tested adolescent resulting in a positive result. There was a high rate of knowledge regarding the most frequent HIV transmission routes: sexual intercourse, contact with infected blood and vertical transmission. In this series, although condom use was the most known way for HIV protection, only 22.2% answered having intercourse protected with this method. CONCLUSION: In this adolescent series, older age was related to higher knowledge in family planning methods; in global despite finding a relatively high knowledge in family planning and HIV related issues, contraception use and HIV protection behaviour was low.

The US National Cholesterol Education Programme Adult Treatment Panel III (NCEP ATP III): prevalence of the metabolic syndrome in postmenopausal Latin American women.

BACKGROUND: Metabolic syndrome (METS) is a strong predictor of cardiovascular risk. Since the prevalence of METS increases after menopause, gynecological routine consultation offers an excellent screening opportunity. OBJECTIVES: To assess the prevalence of METS in Latin American postmenopausal women and factors modifying its risk; as well as to assess the role of simple routine care measurements in the diagnosis of the METS. METHODS: A total of 3965 postmenopausal women, aged 45-64 years, seeking health care at 12 gynecological centers in major Latin American cities were included in this cross-sectional study. The US National Cholesterol Education Programme Adult Treatment Panel III (NCEP ATP III) guidelines were applied to assess METS. This was present if three or more of the following conditions were present: waist circumference > or = 88 cm; blood pressure > or = 130/85 mmHg; fasting plasma triglycerides > or = 150 mg/dl; high density lipoprotein (HDL) cholesterol < 50 mg/dl; glucose > or = 110 mg/dl or subjects were receiving treatment for their condition. RESULTS: The prevalences of having at least two, three, four or five components were 62.5, 35.1, 13.5 and 3.2%, respectively. The prevalence increased from 28.1% in those aged 40-44 years to 42.9% in those aged 60-64 years. The risk of METS detection (multivariate analysis) increased with age (odds ratio (OR) 1.22, 95% confidence interval (CI) 1.03-1.43), time elapsed since menopause (OR 1.18, 95% CI 1.00-1.38), smoking cigarettes (OR 1.40, 95% CI 1.19-1.65), obesity (OR 13.01, 95% CI 10.93-15.49) and hypertension (OR 9.30, 95% CI 7.91-10.94). In contrast, hormone therapy reduces this risk (OR 0.59, 95% CI 0.51-0.70). CONCLUSION: There is a high prevalence of the metabolic syndrome in postmenopausal Latin American women seeking gynecologic health care. Age, years since menopause, obesity and hypertension are strong predictors of this condition.

Menopausal symptoms and associated risk factors among postmenopausal women screened for the metabolic syndrome.

BACKGROUND: Although the frequency of menopausal symptoms may vary according to the studied population, in general severe intensity has been related to lower quality of life. OBJECTIVE: To assess the frequency of menopausal symptoms and involved risk factors in an Ecuadorian postmenopausal population. METHODS: Postmenopausal women that participated in a metabolic syndrome screening program were interviewed with the Menopause-specific quality of life questionnaire (MENQOL) in order to determine the most frequently presenting menopausal symptoms and correlate these symptoms with socio-demographic data and the main results of the screening program. RESULTS: Three hundred and twenty-five postmenopausal women (n = 325) were surveyed with the MENQOL. Mean age of participants was 55.9 +/- 8.1 years (median: 54 years). The most frequently presenting symptoms were: hot flushes (53.3%), sweating (49.2%), poor memory (80.6%), feeling depressed (67.4%), aching in muscles and joints (84%), drying of their skin (85.5%), avoiding intimacy (76.2%) and change in their sexual desire (76.5%). Multivariate analysis determined that abdominal obesity was a significant risk factor for presenting hot flushes, depression and muscle and joint pain. High triglyceride levels were associated to higher rates of sweating and depression. While women with basal hyperglycemia were associated to dry skin and changes in sexual desire in a higher proportion, those who were older and with more years of menopause onset were related less frequently to vasomotor symptoms. Older age was also significantly associated in a higher rate to dry skin. CONCLUSION: In this postmenopausal Ecuadorian population, the frequency of menopausal symptoms, as assessed with the MENQOL, was found to be relatively similar to other Latin and non-Latin American populations and associated to age, hormonal status and related metabolic conditions.
