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.

Distinguishing between quality of life and health status in quality of life research: a meta-analysis.

Despite the increasing acceptance of quality of life (QOL) as a critical endpoint in medical research, there is little consensus regarding the definition of this construct or how it differs from perceived health status. The objective of this analysis was to understand how patients make determinations of QOL and whether QOL can be differentiated from health status. We conducted a meta-analysis of the relationships among two constructs (QOL and perceived health status) and three functioning domains (mental, physical, and social functioning) in 12 chronic disease studies. Instruments used in these studies included the RAND-36, MOS SF-20, EORTC QLQ-30, MILQ and MQOL-HIV. A single, synthesized correlation matrix combining the data from all 12 studies was estimated by generalized least squares. The synthesized matrix was then used to estimate structural equation models. The meta-analysis results indicate that, from the perspective of patients, QOL and health status are distinct constructs. When rating QOL, patients give greater emphasis to mental health than to physical functioning. This pattern is reversed for appraisals of health status, for which physical functioning is more important than mental health. Social functioning did not have a major impact on either construct. We conclude that quality of life and health status are distinct constructs, and that the two terms should not be used interchangeably. Many prominent health status instruments, including utility-based questionnaires and health perception indexes, may be inappropriate for measuring QOL. Evaluations of the effectiveness of medical treatment may differ depending on whether QOL or health status is the study outcome.

Longitudinal Analysis of the Association Between Vasomotor Symptoms and Race/Ethnicity Across the Menopausal Transition: Study of Women’s Health Across the Nation

OBJECTIVES We investigated whether vasomotor symptom reporting or patterns of change in symptom reporting over the perimenopausal transition among women enrolled in a national study differed according to race/ethnicity. We also sought to determine whether racial/ethnic differences were explained by sociodemographic, health, or lifestyle factors. METHODS We followed 3198 women enrolled in the Study of Womens Health Across the Nation during 1996 through 2002. We analyzed frequency of vasomotor symptom reporting using longitudinal multiple logistic regressions. RESULTS Rates of vasomotor symptom reporting were highest among African Americans (adjusted odds ratio [OR]=1.63; 95% confidence interval [CI]=1.21, 2.20). The transition to late perimenopause exhibited the strongest association with vasomotor symptoms (adjusted OR = 6.64; 95% CI = 4.80, 9.20). Other risk factors were age (adjusted OR=1.17; 95% CI=1.13, 1.21), having less than a college education (adjusted OR = 1.91; 95% CI = 1.40, 2.61), increasing body mass index (adjusted OR=1.03 per unit of increase; 95% CI=1.01, 1.04), smoking (adjusted OR=1.63; 95% CI=1.25, 2.12), and anxiety symptoms at baseline (adjusted OR=3.10; 95% CI=2.33, 4.12). CONCLUSIONS Among the risk factors assessed, vasomotor symptoms were most strongly associated with menopausal status. After adjustment for covariates, symptoms were reported most often in all racial/ethnic groups in late perimenopause and nearly as often in postmenopause.

Quality of Life Among Younger Women With Breast Cancer

PURPOSE To describe quality of life (QOL) of younger women 4 to 42 months after breast cancer diagnosis and to identify factors associated with impaired QOL. METHODS A total of 202 women diagnosed with stage I to III breast cancer at age 50 or younger from 4 to 42 months after breast cancer diagnosis previously completed a mailed survey. Global QOL; health-related QOL as measured by the Functional Assessment of Cancer Therapy-Breast Cancer (FACT-B); medical history; symptoms; days of work/activity missed after diagnosis; relationship, sexual, and body image problems; coping strategies; and feelings of preparedness were measured. RESULTS General aches and pains and unhappiness with appearance were reported by more than 70% of women. Hot flashes (P = .0007), pain with sexual intercourse (P = .02), and difficulty with bladder control (P = .002) all significantly increased with age. Global QOL was significantly lower than for a nonpatient sample of younger women (P < .0001). In general, few sociodemographic and medical factors were related to QOL. In multivariate analyses, days of work/usual activity missed immediately after diagnosis; relationship, sexual, or body image problems after diagnosis; and coping strategies were related to almost all QOL domains. Ongoing treatment, vaginal dryness, and feeling unprepared for the impact of breast cancer were related to some domains. CONCLUSION Younger breast cancer survivors are at risk for impaired QOL up to several years after diagnosis. Younger women, especially those at high risk for lower QOL, may need interventions that specifically target their needs related to menopausal symptoms and problems with relationships, sexual functioning, and body image. Preparing younger woman for the impact of breast cancer may also prove beneficial.

A longitudinal analysis of the association between menopause and depression Results from the Massachusetts women's health study

The present article prospectively examines the effect of change in menopause status on depression, while controlling for prior depression. This is a longitudinal follow-up of previous cross-sectional analyses reported by McKinlay, McKinlay, and Brambilla who examined the relative contribution of menopause to depression. The data derive from the Massachusetts Womens Health Study, a 5-year longitudinal study of a cohort of 2565 women aged 45 to 55 years at baseline (1981 to 1982). Results show that prior depression is the variable most predictive of subsequent depression, as measured by the Center for Epidemiologic Studies-Depression (CES-D) scale. Onset of natural menopause was not associated with increased risk of depression. Experiencing a long perimenopausal period (at least 27 months), however, was associated with increased risk of depression. The association between a long perimenopause and depression appeared to be explained by increased menopausal symptoms rather than by the menopause status itself. The observed increase in depression during a lengthy perimenopause appears to be transitory.

Sexual functioning and practices in a multi‐ethnic study of midlife women: Baseline results from swan

This study examined the sexual practices and function of midlife women by ethnicity (African American, Caucasian, Chinese, Hispanic, Japanese) and menopausal status. Sexual behavior was compared in 3,262 women in the baseline cohort of SWAN. Participants were 42 to 52 years old, premenopausal or early perimenopausal, and not hysterectomized or using hormones. Analysis used multivariate proportional odds regression. In our sample, 79% had engaged in sex with a partner in the last 6 months, and a third considered sex to be very important. Common reasons for no sex (n = 676) were lack of partner (67%), lack of interest (33%), and fatigue (16%). Compared with Caucasians, Japanese and Chinese women were less likely, and African Americans more likely, to report sex as very important (p < 0.005). Significant ethnic differences were found for frequency of all practices. Perimenopause status was associated only with higher frequencies of masturbation and pain during intercourse.

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.

Correlates of sexual function among multi-ethnic middle-aged women: results from the Study of Women's Health Across the Nation (SWAN)

Objective:To examine sexual function in a cohort of Baby Boomer women of diverse racial/ethnic backgrounds; to compare differences between pre-and early perimenopausal women; and to identify sociodemographic, health-related, and psychosocial (including psychological, behavioral, and relationship) factors related to sexual function. Design:Six domains of sexual function were studied in 3,167 women in the baseline cohort of the Study of Womens Health Across the Nation (SWAN). Participants were 42 to 52 years old, pre-or early perimenopausal, and not using hormones. The study sample included non-Hispanic white, African American, Hispanic, Chinese, and Japanese women. Results:Early perimenopausal women reported greater pain with intercourse than premenopausal women (P = 0.01), but the two groups did not differ in frequency of sexual intercourse, desire, arousal, or physical or emotional satisfaction. Variables having the greatest association across all outcomes were relationship factors, the perceived importance of sex, attitudes toward aging, and vaginal dryness. Despite controlling for a wide range of variables, we still found ethnic differences for arousal (P < 0.0001), pain (P = 0.03), desire (P < 0.0001), and frequency of sexual intercourse (P = 0.0003). African American women reported higher frequency of sexual intercourse than white women; Hispanic women reported lower physical pleasure and arousal. Chinese women reported more pain and less desire and arousal than the white women, as did the Japanese women, although the only significant difference was for arousal. Conclusions:Relationship variables, attitudes toward sex and aging, vaginal dryness, and cultural background have a greater impact on most aspects of sexual function than the transition to early perimenopause.

Racial/Ethnic Differences in the Prevalence of Depressive Symptoms Among Middle-Aged Women: The Study of Women’s Health Across the Nation (SWAN)

OBJECTIVES We examined racial/ethnic differences in significant depressive symptoms among middle-aged women before and after adjustment for socioeconomic, health-related, and psychosocial characteristics. METHODS Racial/ethnic differences in unadjusted and adjusted prevalence of significant depressive symptoms (score >/= 16 on the Center for Epidemiologic Studies Depression [CES-D] Scale) were assessed with univariate and multiple logistic regressions. RESULTS Twenty-four percent of the sample had a CES-D score of 16 or higher. Unadjusted prevalence varied by race/ethnicity (P <.0001). After adjustment for covariates, racial/ethnic differences overall were no longer significant. CONCLUSIONS Hispanic and African American women had the highest odds, and Chinese and Japanese women had the lowest odds, for a CES-D score of 16 or higher. This variation is in part because of health-related and psychosocial factors that are linked to socioeconomic status.

Sexual Problems in Younger Women After Breast Cancer Surgery

PURPOSE To examine sexual problems in younger women diagnosed with breast cancer during the first year after surgery and to identify sociodemographic, medical, and psychosocial predictors of sexual problems. PATIENTS AND METHODS Women diagnosed with breast cancer age < or = 50 years completed surveys at three time points: within 24 weeks after initial surgery (baseline), 6 weeks after baseline, and 6 months later. Survey items included the Medical Outcomes Study Sexual Functioning Scale, satisfaction with sex life, feeling sexually attractive, body image, marital satisfaction, quality of life, medical history, symptoms, and sociodemographics. Prediagnosis sexual problems were retrospectively ascertained at the initial survey. RESULTS Analyses included 209 women sexually active at baseline (78.6% of total sample). Sexual problems were significantly greater immediately postsurgery compared with retrospective reports before diagnosis (P < .0001). Although problems gradually decreased over time, they were still greater at 1 year postsurgery than before diagnosis. In multivariate analyses controlling for sexual problems at prediagnosis, vaginal dryness, and lower perceived sexual attractiveness were consistently related to greater overall sexual problems. Chemotherapy was related to sexual problems only at baseline except for women who became menopausal as a result of chemotherapy, who continued to have problems. CONCLUSION Findings substantiate the need to address potential sexual problems related to chemotherapy treatment and menopause among younger breast cancer survivors and to counsel women about possible remedies, particularly for vaginal dryness. Increasing feelings of sexual attractiveness may also help sexual problems, especially among women for whom these feelings were altered by surgery or treatment.
