Abstract Objective: Frequency of vasomotor symptoms (VMS) in older women and the contributing factors are largely undefined. We measured the frequency of moderate-to-severe vasomotor symptoms (msVMS) in women ≥60 years of age and examined their characteristics to determine factors that may associate with VMS in older women. Methods: A cross-sectional survey was completed using the Menopause Health Questionnaire from the Data Registry on Experiences of Aging, Menopause, and Sexuality. Data were collected from women presenting for menopause consultation to Mayo Clinic, Rochester, MN, from January 1, 2006 to October 7, 2014. We created a binary variable where women were classified as having msVMS bother if they reported “quite a bit” or “extremely” compared with women reporting “not at all” or “a little bit.” Women with and without msVMS were evaluated by menopause type, self-rated heath, current tobacco, caffeine, and alcohol use, as well as pertinent medication use. Associations between participant characteristics and msVMS were evaluated using logistic regression and a multivariable model with age as a covariate. Interactions between participant characteristics and age were also assessed. Results: Of the 4,956 women presenting for menopause consultation, 921 (18%) were ≥60 years old. Of these, 379 (41.2%) reported msVMS bother. Women with msVMS were more likely to have a history of nonspontaneous menopause and report their health as fair, versus good or excellent. Women reporting current use of hormone therapy (HT) (21%) were less likely to report msVMS compared with those not taking HT (P < 0.001). Conclusions: A substantial number of women seen in a specialty menopause clinic were over age 60 years and reported msVMS, highlighting that VMS may be disruptive in women over a decade past the natural age of menopause.

Our understanding of the complex relationship between menopausal hormone therapy (MHT) and cardiovascular disease (CVD) risk has been informed by detailed analyses in the Women's Health Initiative (WHI), the largest randomized, placebo‐controlled trial evaluating MHT in postmenopausal women. Although the WHI demonstrated increased risk of CVD events with MHT in the overall cohort, subsequent secondary analyses demonstrated that these risks were influenced by the woman's age and time since menopause, with lower absolute risks and hazard ratios for younger than older women. As MHT is the most effective treatment for the vasomotor symptoms of menopause, it is important to understand its risks and how to conduct risk stratification for symptomatic women. In addition to reviewing the WHI findings, studies pre‐ and post‐WHI are reviewed to describe the relationship between MHT and CVD risk in menopausal women. The absolute risks of adverse cardiovascular events for MHT initiated in women close to menopause are low, and all‐cause mortality effects are neutral or even favorable for younger menopausal women. The WHI has advanced and refined our understanding of the relationship between MHT and CVD risk. Although MHT should not be used for CVD prevention, absolute risks of CVD are low when MHT is started close to menopause in healthy women and hazard ratios tend to be lower for younger than older women. For women in early menopause and without contraindications to treatment, the benefits of MHT are likely to outweigh the risks when used for menopausal symptom management.

Abstract Hot flashes have typically been classified as “symptoms of menopause” that should be tolerated or treated until they resolve. However, mounting evidence points to hot flashes as a manifestation of one or several underlying pathophysiological processes. Associations exist between the presence, timing of onset, severity, and duration of hot flashes, and the risk of several neurological (affecting sleep, mood, and cognition) and cardiovascular conditions. In addition, four consistent patterns of vasomotor disturbances have been identified across different countries, making it unlikely that these patterns are solely explained by socioeconomic or cultural factors. The changing hormonal environment of menopause may unmask differences in the autonomic neurovascular control mechanisms that put an individual woman at risk for chronic conditions of aging. These differences may have a genetic basis or may be acquired across the life span and are consistent with the variability of the clinical manifestations of aging observed in women after bilateral oophorectomy. It is time to investigate the pathophysiological mechanisms underlying the four patterns of vasomotor symptoms more closely, and to shift from describing hot flashes as symptoms to be tolerated to manifestations of an underlying autonomic neurovascular dysregulation that need to be addressed.

Abstract Objective: Sleep disturbance and sexual dysfunction are common in menopause; however, the nature of their association is unclear. The present study aimed to determine whether sleep characteristics were associated with sexual activity and sexual satisfaction. Methods: Sexual function in the last year and sleep characteristics (past 4 wk) were assessed by self-report at baseline for 93,668 women age 50 to 79 years enrolled in the Women's Health Initiative (WHI) Observational Study (OS). Insomnia was measured using the validated WHI Insomnia Rating Scale. Sleep-disordered breathing (SDB) risk was assessed using questions adapted from the Berlin Questionnaire. Using multivariate logistic regression, we examined cross-sectional associations between sleep measures and two indicators of sexual function: partnered sexual activity and sexual satisfaction within the last year. Results: Fifty-six percent overall reported being somewhat or very satisfied with their current sexual activity, and 52% reported partnered sexual activity within the last year. Insomnia prevalence was 31%. After multivariable adjustment, higher insomnia scores were associated with lower odds of sexual satisfaction (yes/no) (odds ratio [OR] 0.92, 95% CI, 0.87-0.96). Short sleep duration (<7-8 h) was associated with lower odds of partnered sexual activity (yes/no) (≤5 h, OR 0.88, 95% CI, 0.80-0.96) and less sexual satisfaction (≤5 h, OR 0.88, 95% CI, 0.81-0.95). Conclusions: Shorter sleep durations and higher insomnia scores were associated with decreased sexual function, even after adjustment for potential confounders, suggesting the importance of sufficient, high-quality sleep for sexual function. Longitudinal investigation of sleep and its impact on sexual function postmenopause will clarify this relationship.

Osteoporosis, defined as low bone mass leading to increased fracture risk, is a major health problem that affects approximately 10 million Americans. The aging U.S. population is predicted to contribute to as much as a 50% increase in prevalence by 2025. Although common, osteoporosis can be clinically silent, and without prevention and screening, the costs of osteoporotic fracture–related morbidity and mortality will burden the U.S. healthcare system. This is a particularly relevant concern in the context of diminishing health care resources. Dual-energy X-ray absorptiometry is the most widely used, validated technique for measuring bone mineral density (BMD) and diagnosing osteoporosis. Cost-effectiveness analyses support early detection and treatment of high-risk patients with antiresorptive medications such as bisphosphonates. Moreover, optimization of bone health throughout life can help prevent osteoporosis. Current guidelines recommend screening women by age 65 years, but because no guidelines for screening intervals exist, decisions are made on the basis of clinical judgment alone. Although the recent literature provides some guidance, this review further explores current recommendations in light of newer evidence to provide more clarity on prevention, screening, and management strategies for patients with osteoporosis in the primary care setting.
