Is there a menopausal syndrome? Menopausal status and symptoms across racial/ethnic groups.

In recent years, research on menopausal symptomalogy has focused on identifying symptom groupings experienced by women as they progress from premenopausal to postmenopausal status. However, most of these studies have been conducted among Caucasian women from western cultures. This leaves open the question of whether the findings from these studies can be extended to women of other racial/ethnic groups or cultures. Furthermore, many of the previous studies have been conducted on relatively small samples. This paper addresses the diversity of the menopause experience by comparing symptom reporting in a large cross-sectional survey of women aged 40-55 years among racial/ethnic groups of women in the United States (Caucasian, African-American, Chinese, Japanese, and Hispanic). Evaluation of the extent to which symptoms group together and consistently relate to menopausal status across these five samples provides evidence for or against a universal menopausal syndrome. The specific research questions addressed in this paper are: (1) How does the factor structure of symptoms among mid-aged women compare across racial/ethnic groups? (2) Is symptom reporting related to race/ethnicity or menopausal status? and (3) Does the relation between menopausal status and symptoms vary across racial/ethnic groups? Analyses are based on 14,906 women who participated in the multi-ethnic, multi-race, multi-site study of mid-aged women called the Study of Womens Health Across the Nation (SWAN). Study participants completed a 15-min telephone or in-person interview that contained questions on a variety of health-related topics. Items of interest for these analyses include symptoms, menstrual history (to assess menopausal status), health status, and sociodemographics. Factor analysis results showed that across all five racial/ethnic groups, two consistent factors emerged; one consisting of clearly menopausal symptoms -- hot flashes and night sweats -- and the other consisting of psychological and psychosomatic symptoms. Results of regression analyses showed racial/ethnic differences in symptom reporting, as well as differences by menopausal status. Controlling for age, education, health, and economic strain, Caucasian women reported significantly more psychosomatic symptoms than other racial/ethnic groups. African-American women reported significantly more vasomotor symptoms. Perimenopausal women, hormone users, and women who had a surgical menopause reported significantly more vasomotor symptoms. All of these groups, plus postmenopausal women, reported significantly more vasomotor symptoms than premenopausal women. The pattern of results argues against a universal menopausal syndrome consisting of a variety of vasomotor and psychological symptoms.

Is there an association between menopause status and sexual functioning

Objective: The purpose of this study was to address whether: (1) there is an association between menopause status and various aspects of sexual functioning, and (2) the relative contributions of menopause status and other variables to various aspects of sexual functioning. Design: Analyses are based on 200 women from the Massachusetts Womens Health Study II, a population‐based sample of women transitioning through the menopause who were not HRT users, who had not had a surgical menopause, and who had partners. The women were classified as pre‐, peri‐, or postmenopausal according to menstrual cycle characteristics. Estradiol, estrone, and follicle‐stimulating hormone were also measured. Sexual functioning was measured in terms of satisfaction, desire, frequency of sexual intercourse, belief that interest declines with age, arousal compared with a younger age, difficulty reaching orgasm, and pain. Predictor variables included sociodemographics, health, vasomotor symptoms, psychological variables, partner variables, and lifestyle behaviors. Results: Menopause status was significantly related to lower sexual desire, a belief that interest in sexual activity declines with age, and womens reports of decreased arousal compared with when in their 40s. Menopause status was unrelated to other aspects of sexual functioning in either unadjusted or multiple regression analyses. In analyses in which log estradiol (E2) was included in addition to menopause status, log E2 was only related to pain. In multiple regression analyses, other factors such as health, marital status (or new partner), mental health, and smoking had a greater impact on womens sexual functioning than menopause status. Conclusions: Menopause status, but not E2, is related to some, but not all, aspects of sexual functioning. This may be due to menopause per se or other factors associated with menopause and aging (e.g., increased sexual dysfunction among aging men). Menopause status has a smaller impact on sexual functioning than health or other factors. (Menopause 2000;7:297‐309.

Longitudinal study of hormone levels and depression among women transitioning through menopause

Objective To address the association between depression and absolute levels of estradiol, and change in estradiol, among women during the menopausal transition. Methods This was a prospective, observational study conducted in Massachusetts, USA. Analyses reported here are based on the first three interviews following baseline (T1–T3). The participants were 309 women aged initially 43–53 years, who contributed a total of 728 observations (mean number of observations per subject 2.36). The main outcome measure was depression as measured by the Center for Epidemiologic Studies-Depression (CES-D) scale. Results CES-D score was not significantly associated with menopause status categories, nor was it associated with annual change in estradiol level (E2) (p = 0.19). The unadjusted association between log E2 and CES-D was negative (odds ratio 0.69) and statistically significant (p = 0.03). Upon adjustment for symptoms, however, the association remained negative but was no longer statistically significant (p = 0.26). Hot flushes/night sweats were positively associated with CES-D (p = 0.04), and trouble sleeping was strongly positively related to CES-D (p < 0.001). Conclusions Results provide strong support for the domino or symptom hypothesis, which posits that depressed mood is caused by vasomotor symptoms associated with changing estrogen levels. Estradiol did not have a direct effect, independent of symptoms. This study adds to the body of literature suggesting that any association found between menopause and depression is most likely to be explained by other factors, such as symptoms and sleep problems. Findings also highlight the importance of studying the complex relationship between hormone levels, sleep problems and vasomotor symptoms during the menopausal transition.

Relation of Dehydroepiandrosterone and Dehydroepiandrosterone Sulfate with Cardiovascular Disease Risk Factors in Women: Longitudinal Results from the Massachusetts Women's Health Study

Low circulating levels of the adrenal steroids dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) are thought to be associated with increased risk of cardiovascular disease (CVD) in men. In women, either a positive or null association with CVD has been found. The nature of the relation between DHEAS and CVD risk factors in women is unclear and is based on cross-sectional data. We present results from a longitudinal investigation of serum DHEA and DHEAS and cardiovascular disease risk factors in 236 women, initially 50-60 years old, from a population-based prospective (1986-1995) study of the menopausal transition. We used generalized estimating equations to model the relation of serum DHEA and DHEAS to systolic and diastolic blood pressure and serum levels of total cholesterol, high density lipoprotein cholesterol, and apolipoproteins A and B, adjusting for other factors related to CVD. Both DHEA and DHEAS were positively related to diastolic and systolic blood pressure, and DHEAS was negatively related to apolipoprotein A. DHEA and DHEAS were also positively related to smoking, alcohol use, estrone, and estradiol levels, and inversely related to age. Our results suggest that higher levels of DHEA and DHEAS in middle-aged women may indicate increased CVD risk.
