Women and menopause: beliefs, attitudes, and behaviors. The North American Menopause Society 1997 Menopause Survey.

OBJECTIVE: The main purpose in organizing this survey was to collect information relevant to The North American Menopause Society's (NAMS) educational mission and to document women's knowledge of, and attitudes toward, menopause. DESIGN: During June-July 1997, The Gallup Organization conducted 750 telephone interviews with a randomly selected sample of women 45-60 years of age from across the United States. Women were asked about their sources of information on menopause, what changes in health they anticipated as a result of menopause, why they used hormone therapy, and their attitudes toward menopause as a natural or a medical event. RESULTS: Women are more likely to believe that depression and irritability are associated with menopause than heart disease, but only a few associate menopause with an increasing vulnerability to either memory loss or Alzheimer's disease. Relief of physical symptoms of menopause was mentioned as the reason for starting hormone therapy more often than to protect against osteoporosis (25% relative to 15%), or to prevent stroke or a heart attack (10%), or to reduce the risk of developing Alzheimer's disease (2%). The single main source of women's information on menopause was a health professional (49%). The majority of women who were already menopausal or experiencing menstrual changes expressed an attitude toward menopause that was either neutral (42%) or positive (36%). CONCLUSIONS: Women are divided in their views of menopause, some seeing it as a medical condition requiring medical treatment, whereas others see it as a natural transition to be managed by "natural" means. Providing women with accurate, up-to-date information and enhancing communication between healthcare providers and menopausal women remain the challenges for NAMS.

The North American Menopause Society 1998 Menopause Survey. Part I: Postmenopausal women's perceptions about menopause and midlife.

OBJECTIVE: To collect information relevant to the mission of The North American Menopause Society (NAMS)--i.e., increasing understanding of menopause--by assessing perceptions held by postmenopausal women in the United States aged 50 to 65 years regarding their menopause transition and early postmenopausal years. DESIGN: During the period from June to July 1998, The Gallup Organization conducted 752 telephone interviews with a randomly selected sample of postmenopausal women aged 50 to 65 years from across the United States, based on questions developed by NAMS. In Part I of this survey, women were asked about their personal experiences with menopause, their health-related lifestyle changes since premenopause, their frequency of discussing menopause, and their rating of preparedness for menopause. Part II of this survey, including use of hormone replacement therapy as well as use of healthcare services, will be reported in a future communication from NAMS. RESULTS: The majority (51%) of the postmenopausal women surveyed reported being happiest and most fulfilled between the ages of 50 to 65 years, compared with when they were in their 20s (10%), 30s (17%), or 40s (16%). Many areas of their lives had improved since menopause, including family/home life, sense of personal fulfillment, ability to focus on hobbies or other interests, relationship with spouse/partner, and friendships. A majority (51%) said their sexual relationships had remained unchanged. Approximately three-quarters of women surveyed reported making some type of health-related lifestyle change, such as stopping smoking, at menopause/midlife. Women who had undergone hysterectomy expressed more improvement than women with an intact uterus, especially in the areas of sexual relationships, spouse/partner relationships, personal fulfillment, and physical health; data are not available regarding the health state of these women before surgery or whether they experienced surgical menopause, but this improvement did not appear to be the result of hormone replacement therapy. Women tended to look to women from their own generation for menopause-related information and believed that they have prepared the younger generation for menopause better than they were prepared by their mothers' generation. Those surveyed advised younger women to engage in healthful activities and become knowledgeable so that they could make informed health decisions. CONCLUSIONS: Although the postmenopausal women surveyed had differing views of menopause as well as their perceptions of postmenopause compared with premenopause, the majority viewed menopause and midlife as the beginning of many positive changes in their lives and health. Hysterectomy was a factor associated with improved sexual relationships, spouse/partner relationships, sense of personal fulfillment, and physical health.

Decreased bone mineral density associated with early menopause progresses for at least ten years: cross-sectional comparisons between early and normal menopausal women.

To establish whether early onset of menopause carries an increased risk of osteoporosis, we compared the bone mineral density (BMD) of the second to fourth lumbar vertebrae (L2-4) between 18 women who had menopause before 43 years of age (early menopause group) and 19 women who had menopause after reaching 43 years of age (normal menopause group). Serum levels of calcium, phosphorus, calcitonin, intact parathyroid hormone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), and alkaline phosphatase activity were measured, and urine samples were analyzed to derive calcium/creatinine, hydroxyproline/creatinine, pyridinoline/creatinine, and deoxypyridinoline/creatinine (D-Pyr/Cr) ratios. Mean BMD was significantly lower in the early menopause group than in the normal menopause group, and individual BMD values in about half of the subjects in the former group were below the fracture threshold for Japanese women. Serum concentrations of LH, FSH, and E2 were slightly, but not significantly, lower in the early menopause group than in the normal menopause group. The D-Pyr/Cr ratio was significantly higher in the early menopause group than in the normal menopause group. There was no correlation between L2-4 BMD and age or the number of years after menopause in the normal menopause group, but both age and the number of years after menopause were negatively correlated with L2-4 BMD in the early menopause group. These results indicate that BMD in women who have early menopause continues to decline for up to 10 years, and that menopause and aging increase the risk of osteoporosis.

[Studies on the bone metabolisms in either after natural menopause or surgical menopause: implications of IGF-IGFBP system for postmenopausal osteoporosis].

It is well established that accelerated bone loss occurs in association with estrogen deprivation as seen following the natural menopause and in premenopausal women undergoing surgical oophorectomy (i.e., surgical menopause). We have measured serum levels of bone biochemical markers after both natural menopause and surgical menopause. Circulating levels of insulin-like growth factor-I (IGF-I), which is considered to be the local regulator of osteoblast activity and one of its binding protein, insulin-like growth factor binding protein-4 (IGFBP-4) which binds to IGF-I and suppress its biological activity, were also measured. Bone mineral density measured by dual energy X-ray absorptiometry was decreased more rapidly after surgical menopause. A concomitantly higher rate of bone turnover as assessed by bone biochemical markers was observed after surgical menopause, and thus the levels of procollagen type I C-peptide, pyridinoline and deoxypyridinoline were increased. The serum levels of IGF-I were significantly reduced after natural menopause compared with that after surgical menopause. The levels of IGF-I were correlated with bone mineral density after natural menopause (r = 0.62, p < 0.001), but no significant correlation was observed between these two variables after surgical menopause. The binding activity of IGFBP-4 was significantly greater after surgical menopause than after natural menopause. A stronger inverse correlation existed between the binding activity of IGFBP-4 and bone mineral density after surgical menopause (r = -0.90, p < 0.001) compared to that after natural menopause (r = -0.29, p < 0.05). The simplest explanation is that whereas the loss of bone depends upon the decreased level of IGF-I after natural menopause, after surgical menopause it depends upon the increased level of IGFBP-4.

Assignment to menopausal status and estimation of age at menopause for women with missing or invalid data--a probabilistic approach with weighting factors in a large-scale epidemiological study.

OBJECTIVE: Gynaecologic surgeries and hormone medication increasingly interfere with the concept of determining menopausal status based on self-reported data about the last menstrual period-an approach frequently applied in epidemiological studies. This analysis compared different approaches of menopausal status determination, including a probabilistic approach that was developed to reduce misclassification of menopausal status. METHODS: Interview and questionnaire data relating to hormone status from about 16,000 German women were used to determine menopausal status using different approaches: menses based, age based, self-assessment based, and a probabilistic approach. RESULTS: Applying strict menses-based criteria, 29.1% of the women were found to be with undetermined menopausal status. The probabilistic approach was applied to determine menopausal status and age at menopause for these women. The proposed approach uses the current age of the women with undetermined menopausal status, and the relative age-dependent frequencies of pre- or postmenopausal status among those with natural menopausal status to calculate weighting factors, which represent the probabilities of being pre- and postmenopausal of each woman previously undetermined. Correspondingly, the missing age at menopause was estimated with the same probabilistic approach. Applying various approaches to determine menopausal status, the ratio of pre- to postmenopausal women differed considerably, ranging from 1.03 to 1.61. In addition, considerable differences were observed with respect to the number of missing values for both menopausal status and age at menopause. CONCLUSION: The probabilistic approach allowed to estimate menopausal status and age at menopause with the advantage that all available information from the entire study population and from the individual is used.

Menstrual cycle length preceding menopause in relation to age at menopause.

OBJECTIVES: In one of the earlier hypotheses of the etiology of breast cancer (Korenman's 'oestrogen window' hypothesis (1981)), it was assumed that women with a later age at menopause have a longer period with irregular cycles preceding menopause than women with an early menopause. This assumption was tested in a prospective study. METHODS: Subjects were 628 women, born between 1932 and 1941, who had participated in a breast cancer screening project in Utrecht, The Netherlands (the DOM-project) in 1982-1985, and who were still menstruating at that time. The women had filled out a questionnaire and a menstrual calendar every 2 years to determine their age at menopause prospectively. The women had not used oral contraceptives or medicines for menopausal complaints and had reached natural menopause by 1992. The median of the mean menstrual cycle length per woman and the median of the standard deviation of the mean menstrual cycle length per woman were plotted against number of years prior to menopause in three categories of age at menopause (44-49; 50-54; 55-59). RESULTS: During the 9 years prior to menopause, women with a late age at menopause have a somewhat higher mean menstrual cycle length than women with a younger age at menopause (P = 0.0008). Cycle length variability in the 9 years prior to menopause is not statistically significantly different between the three categories of age at menopause (P = 0.16). CONCLUSIONS: The assumption that women with a late age at menopause have a longer period with irregular cycles than women with an earlier age at menopause was not corroborated by our results.

Is the measurement of placental protein-14 and CA-125 in plasma and uterine flushings useful in the evaluation of peri-menopausal and post-menopausal bleeding?

In this prospective study, we examined the possible diagnostic value of the measurement of two endometrial proteins, placental protein-14 (PP14) and CA-125, in the evaluation of pre- and post-menopausal bleeding. Concentrations of these two proteins were measured in plasma and uterine flushings obtained from 139 pre- and post-menopausal women with bleeding problems, and 26 normal post-menopausal control women without bleeding. Endometrial biopsy samples were also obtained for histological study. Concentrations of PP14 in both the plasma and uterine flushings in post-menopausal women were significantly lower (P < 0.001) than those of control pre-menopausal women. In post-menopausal women, the concentrations of PP14 (mean +/- SEM) in both plasma and flushing were significantly higher (P < 0.001) in women with endometrial adenocarcinoma (46.9+/-7.5 ng/ml plasma; 3350+/-1711 ng/ml flushing) than in the controls (7.6+/-1.3 ng/ml plasma; 125+/-27 ng/ml flushing) or in women with post-menopausal bleeding and atrophic endometrium (20.4+/-2.1 ng/ml plasma; 453+/-167 ng/ml flushing). In contrast CA-125 concentrations in plasma and flushings were similar in post-menopausal and pre-menopausal women. Plasma concentrations of CA-125 were higher in post-menopausal women with adenocarcinoma (29.1+/-7.4 IU/ml) than in those with post-menopausal bleeding and atrophic endometrium (21.8+/-2 IU/ml) (P < 0.05) or control post-menopausal subjects (16.1+/-2.1 IU/ml) (P < 0.01). CA-125 concentrations in uterine flushings were not significantly different in any group of post-menopausal women. The results show that concentrations of PP14 are correlated more strongly to endometrial histopathology than those of CA-125 in pre- and post-menopausal women. Elevated PP14 concentrations are also associated with the presence of endometrial adenocarcinoma and may have a potential to be used as a marker for this disease.

Increased risk of early menopausal transition and natural menopause after poor response at first IVF treatment.

BACKGROUND: Our aim was to examine whether women who had a low number of retrieved oocytes at their first IVF attempt reach the menopausal transition and/or the natural menopause earlier than women of similar ages with a high number of retrieved oocytes. METHODS: We conducted a retrospective cohort study among women in The Netherlands who received IVF treatment between 1983 and 1995. For the present study, we selected all cohort members who had a regular menstrual cycle at the time of the first visit to the gynaecologist (n = 4601). After a median follow-up of 5.5 years, 3871 (84%) women still had a regular menstrual cycle pattern, 547 (12%) women had entered the menopausal transition (i.e. no menses for 3-11 months, use of HRT or irregular menstrual cycles) and 27 (1%) women had reached natural menopause. We examined whether the quantity and the quality of the retrieved oocytes were related to an early menopausal transition and early menopause. The live birth rate per embryo transfer was used as indicative of the quality of the oocytes. RESULTS: The age-adjusted odds ratio (OR) for having entered the menopausal transition/natural menopause for women with a poor response (0-3 oocytes) at their first IVF attempt was 3.1 [95% confidence interval (CI) 2.4-3.8] compared with women with a normal response (>3 oocytes). Women who were stimulated with gonadotrophins during IVF treatment but did not undergo an IVF puncture because of an anticipated poor response (cancelled IVF cycle) had an age-adjusted OR of 3.2 (95% CI 2.3-4.3). There was no significant difference in the odds of reaching the menopausal transition/natural menopause, after adjustment for age and the number or retrieved oocytes, between women who did and did not have a live birth following their first embryo transfer (OR = 1.3; 95% CI 0.95-1.7). CONCLUSIONS: These results indicate that a low remaining quantity of oocytes, as reflected by a low number of retrieved oocytes at first IVF treatment, is an important predictor of the risk of an early menopausal transition/natural menopause. The quality of the oocytes did not affect the risk of an early menopausal transition/natural menopause once the number of retrieved oocytes had been taken into account. Our findings support the concept that the number of remaining follicles in the ovaries is one of the main aspects of reproductive ageing.

Changes in Australian women's perception of the menopause and menopausal symptoms before and after the climacteric.

The symptoms and perceptions of menopause of 60 Australian women were studied, by questionnaire, when they were premenopausal and 10 years later when they were postmenopausal. Menopausal symptoms expected and experienced by the women were compared, fewer women experiencing hot flushes, headache, depression and nervousness and more experiencing insomnia, increase in appetite, abdominal fullness, numbness and muscular problems. The symptoms women thought were due to hormonal changes at menopause were compared. In 1993 more women cited osteoporosis, insomnia, loss of libido, obesity and loss of muscle tone as due to hormone change while fewer cited depression. The premenstrual symptoms and their severity experienced by a woman when she was premenopausal significantly predicts the type and severity of the menopausal symptoms experienced by the woman. The expected menopausal symptoms and their severity cited by a woman also significantly predicts the type of severity of the menopausal symptoms experienced. More premenstrual symptoms predict the menopausal symptoms than those menopausal symptoms the women expected. The expectation menopause will be 'a relief' or 'a nuisance' significantly predicted the overall menopause experience described by the women. Their negative attitudes about doctors' understanding and information available about menopause remained unchanged but they forget menstrual cycle problems over the 10 years. The results suggest a possible physiological basis for premenstrual and menopausal symptoms. Assistance for women with their premenstrual and menstrual cycle symptoms may improve their quality of life at menopause.

Psychologic distress during the menopausal years in women attending a menopause clinic.

OBJECTIVE: This study measures psychologic distress in women attending a menopause clinic to determine if significant differences exist between peri-menopausal and menopausal women. METHOD: Consecutive women attending a university hospital menopause clinic were administered the Brief Symptom Inventory (BSI) and a study questionnaire to determine menopausal symptoms, menstrual cycle status, and use of hormone replacement therapy (HRT). The BSI results were compared between menopausal and perimenopausal women, and to a normative sample of middle-aged women who were nonpatients. RESULTS: Two hundred and fifty-nine menopause clinic women completed the questionnaire: 113 perimenopausal and 146 menopausal women. There was significantly greater psychologic distress on the BSI among perimenopausal as compared to menopausal women on the global severity index, and each of the anxiety, hostility, somatization, depression, paranoid, and psychoticism subscales. Perimenopausal women met BSI caseness severity criteria significantly more often than did menopausal women on the global severity index, and on the subscales for depression, anxiety, and psychoticism. On the BSI, menopausal women showed results similar to those of a normative sample of nonpatient middle-aged women. CONCLUSIONS: Perimenopausal women attending menopause clinics have significantly higher levels of psychologic distress meeting case severity criteria on the BSI. Further research is warranted to define the subgroups of perimenopausal women who are at increased risk, in the hopes of developing effective interventions.

Psychosocial factors associated with perceived psychological health, perception of menopause and sexual satisfaction in menopausal women and controls.

OBJECTIVES: The study investigated factors associated with attitude towards sex-role, self-image and marital satisfaction on psychological health status, perception of menopause and sexual satisfaction in climacteric women in Ibadan, Nigeria. SUBJECTS AND METHODS: 45 female participants were randomly selected from Ibadan. The mean age was 51.42 +/- 8.05 years (range = 36 - 70 years). The mean age for the 13 non-menopausal women was 42.79 +/- 3. 91 years (range = 42 - 47 years) while the mean age for the 32 menopausal women was 5.16 +/- 6.08 years (range = 47 - 70 years). The mean age of the children of the participants was 16.05 +/- 8.09 years (range = 1 - 36 years). A questionnaire having several subsections (consisting of the psychological health status of women in the climacteric, attitude towards sex role, perception of menopause, social support, marital satisfaction, self-image and sexuality scales was used for the assessment. RESULTS: Post-Menopausal women reported better psychological health compared to the pre-menopausal women (t = 1.86, p < .05) but no significant differences in their attitude to sex role. Post menopausal women had more positive attitude to sex (t = 3.15, p < .01) and were more knowledgeable about menopause (t = 2.15, p < .03). Women with conservative/reactionary preference for traditional sex roles reported negative perception of menopause compared to those with liberal attitude toward sex role (t = 1.82, p < 0.05). Menopausal Status, Educational level and social support predicted positive attitude to sex, (F = 3.62, P < .01). Age, self-image and attitude to sex domain of the marital satisfaction scale predicted better psychological health, and marital cordiality predicted better psychological health as measured by GIIQ (R2 = 25, beta = -43, t = -2.38, P < .02). Marital satisfaction significantly predicted better sexuality, (F = 5.47, R square = 0.11, p <0.05). Sources of information on menopause included health institutions, books, doctors, and books/health workers. CONCLUSION: The study highlights the need for sensitizing menopausal Nigerian women on how to improve their self-image, marital satisfaction, and sexual satisfaction. Conventional treatment options emphasizing hormone replacement therapy, need for nutritional supplement, dietary changes, marital and sex therapy are emphasized.

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 Women's 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.

Menopausal status, hormone replacement therapy use and risk of self-reported physician-diagnosed osteoarthritis in women attending menopause clinics in Italy.

OBJECTIVE: In order to offer data on the association between menopausal status, hormone replacement therapy use and risk of self-reported physician-diagnosed osteoarthritis (OA) in women around menopause, we analyzed information collected in the framework of a large epidemiological study conducted in Italy. METHODS: Since 1997, a large cross sectional study has been conducting on the characteristics of women around menopause attending a network of first level outpatients menopause clinics in Italy for general counseling about menopause or treatment of menopausal symptoms. Eligible for the study were women consecutively observed at the participating centers. Up to March 2000, a total of 42464 women (mean age 53 years) were observed. Women were asked, using the same questionnaire, about their general characteristics and habits, and if they suffer of OA diagnosed by a physician requiring medical or surgical treatment. RESULTS: A total of 12521 women reported OA. The risk of OA increased with body mass index (BMI), the odds ratio, OR, being for BMI>or equal to 27 versus <24, 1.56 (95%CI 1.47-1.64). The risk increased with a history of osteoporosis/osteopenia (OR 1.65, 95%CI 1.57-1.74) and was lower in more educated women (OR high school/university degree vs. primary school degree 0.79, 95%CI 0.75-0.84). Considering menopausal status, women in spontaneous or surgical menopause were, at increased risk of OA (OR 1.13, 95%CI 1.07-1.21, and 1.18, 95%CI 1.08-1.28, respectively, in women in surgical and spontaneous menopause). No clear relationship, however, emerged with age at menopause. Ever hormonal replacement therapy users were at decreased risk of OA, the OR being for ever users in comparison with never 0.73 (95%CI 0.69-0.78). CONCLUSION: This analysis gives some epidemiological support to the hypothesis that estrogen deficiency may increased the risk of OA.

Blood pressure and metabolic profile after surgical menopause: comparison with fertile and naturally-menopausal women.

In 1978 a random sample (367 men and 568 women aged 18-65 years) taken from the general population of a north-eastern Italian town was screened for cardiovascular risk; 16 years later, the women were invited to a second screening. Three groups were identified at the initial screening (fertile, naturally menopausal and surgically menopausal) and four in the longitudinal study (137 remained fertile during the whole study, 205 became naturally menopausal, 56 were ovariectomised and 127 were already going through the menopause). The protocol included a questionnaire, blood pressure (BP) measurement, and blood exams. Continuous variables were adjusted for confounders. Systolic BP, prevalence of hypertension, cholesterol, glycaemia and uricaemia were similar, whereas diastolic and triglycerides (TG) were lower in surgically-menopausal than in fertile women (P < 0.001). No significant difference in 16 years' variation from baseline was observed between the four groups, although women who remained fertile showed the smallest increases. In particular, neither systolic or diastolic BP increases differed between the women who were oophorectimised and those who remained fertile. 'Fertile status' was rejected from the logistic equation of incidence of hypertension, and 'age of menopause' was also rejected when this analysis was repeated in ovariectomised women. New coronary artery disease (angina pectoris or myocardial infarction) was observed in one ovariectomised woman, in three naturally menopausal, and in 13 already menopausal women which seemed to reflect the age trend. No new cases were observed in women who remained fertile. In conclusion, in Italian women surgical menopause, similarly to natural menopause, is devoid of any negative prognostic effect.

Somatotropic axis and body weight in pre-menopausal and post-menopausal women: evidence for a neuroendocrine derangement, in absence of changes of insulin-like growth factor binding protein concentrations.

The altered function of the somatotropic axis observed in perimenopause may underlie the changes in body weight and fat distribution. The aim of the present study was to evaluate, in pre-menopausal and post-menopausal women with body mass index (BMI) > or = or <25, the basal plasma levels of growth hormone (GH), insulin-like growth factor (IGF)-I and -II, IGF binding protein (IGFBP)-1 and -3, and the response of GH and IGFBP-1 and -3 to GH releasing hormone (GHRH) and GHRH plus arginine tests. GH and IGF-I basal concentrations were significantly higher in pre-menopausal than in post-menopausal women, while IGF-II, IGFBP-1 and IGFBP-3 concentrations did not vary significantly. IGFBP-1, but not IGFBP-3, concentrations were higher in lean than in obese patients. Insulin concentrations were significantly higher in obese patients, while no differences were observed between pre-menopausal and post-menopausal women. In all subjects, GH concentrations increased significantly during GHRH test; pre-menopausal and lean women showed a higher response compared to post-menopausal and obese women. The GHRH plus arginine test stimulated GH response in all women, irrespective of age and BMI. IGFBP-1 and -3 concentrations did not vary in response to GHRH or GHRH plus arginine tests. The somatotropic axis undergoes modifications in post-menopausal women, apparently not involving IGFBP-1 and -3. Arginine infusion restores the response of GH to GHRH, in both post-menopausal and obese subjects. A somatostatinergic hyperactivity at the climateric period may underlie the changes both in body weight and somatotropic axis.

Clinical outcomes of post-operative locoregional radiotherapy in pre-menopausal and post-menopausal Chinese women with breast cancer.

BACKGROUND AND PURPOSES: Recent randomized studies from the West show that post-operative locoregional radiotherapy improves survival in lymph node (LN) positive pre-menopausal women with breast cancer but this benefit has not been established in the Chinese population. There is no published study on clinical outcomes (locoregional recurrence, survival and toxicities) of post-operative locoregional radiotherapy in Chinese women with breast cancer. MATERIALS AND METHODS: We conducted a retrospective study of 399 female Chinese patients with breast cancer who had received post-mastectomy locoregional radiotherapy in our center between 1984 and 1990. The patients were stratified according to tumor size, menopausal and LN status. We analyzed the incidence and pattern of locoregional recurrence, distant recurrence, survival rates and toxicity related to radiotherapy. RESULTS: Of the 399 patients 216 were pre-menopausal and 183 were post-menopausal. The mean age was 49.3 years (23-83). Distribution of tumor size and LN status of the two groups was similar. Median follow-up was 71.9 months. Locoregional recurrence occurred in 57 (14.3%) patients (pre-menopausal 24 (11.1%); post-menopausal 33 (18.3%) P=0.489). Recurrence was more common in LN positive patients (18.2%) than LN negative patients (9.2%). The pattern of locoregional recurrence was: chest wall 24, axilla LN 12, supraclavicular LN 10, chest plus LN 11. The distant recurrence rate was 39.6% for all patients and 75.4% for patients with locoregional recurrences. The overall 10-year survival rate for all patients was 54%. For LN positive patients the 10-year survival rate of pre-menopausal and post-menopausal women was 38 and 51%, respectively (P=0.207), and for LN negative patients the rate was 73 and 70%, respectively (P=0.603). Acute skin toxicity included redness (30.8%), dry desquamation (12.8%), and wet desquamation (6. 8%). Long-term toxicities included skin atrophy (0.3%), telangectasia (3.3%), pneumonitis (2.8%) and brachial plexus palsy (1.3%). CONCLUSIONS: In our series Chinese patients with node-positive breast cancer have a relatively high locoregional recurrence rate in spite of mastectomy and post-operative radiotherapy. Limited use of adjuvant system chemotherapy may account, at least in part, for this finding. Clinical outcomes of post-operative radiotherapy in pre-menopausal and post-menopausal breast cancer patients are similar.

Menopausal transition: predicting time to menopause for women 44 years or older from simple questions on menstrual variability.

OBJECTIVE: To assess whether menstrual variability predicts time to menopause. DESIGN: Analyses drew on 326 menstruating women, aged 44 to 56, who were followed until they reached menopause or the study ended. The women provided data on their menstrual characteristics at intake. We evaluated the utility of six definitions of menstrual variability for predicting time to ascertained menopause (final menstrual period + 12 months): (1) more than 90 days since the most recent menstrual period (n = 20); (2) 60 or more days of amenorrhea during the previous year (n = 71); (3) cycle lengths that varied by 19 or more days (n = 106); (4) cycle lengths too variable to report a usual length (n = 29); (5) cycles less regular than they had been at age 40 (n = 107); and (6) change in the duration or heaviness of menstrual flow compared with age 40 (n = 255). In addition, we evaluated hot flashes or night sweats during the previous week (n = 50) and age 50 or more years (n = 60) as predictors. RESULTS: Definitions 1 to 5 predicted time to menopause; definition 6 did not. Definition 1 had the highest positive predictive value for ascertained menopause within 2 years and within 4 years; definitions 2 and 4 had low to moderate positive predictive values for ascertained menopause within 2 years but good positive predictive values for ascertained menopause within 4 years. For ascertained menopause within 2 years, definition 2 showed the best balance of sensitivity (94%) and specificity (91%). CONCLUSION: Simple questions about menstrual variability elicit information that is informative about proximity to menopause.

Attitudes towards menopause in a group of women followed in a public service for menopause counseling.

This preliminary study addressed some specific attitudes towards menopause, and behavioral styles in menopausal women. The study was conducted during the period January-May 1998 at the Menopausal Service of the Magenta Hospital (Milano) in 88 women, representing almost one half of the patients followed during that period; 43 women were treated with HRT. Some traits characterizing women's life during menopause were examined, such as presence of disturbing physical symptoms, changes in interests and discovery of new interests, and feelings of loss and uselessness. We used different psychological tests in order to evaluate anxiety and depression, in particular, the STAI (State-Trait Anxiety Inventory), the SDS (Self-rating Depression Scale), and 16 cartoon-like images representing stereotypes of menopause. The answers of our subjects showed high individual variation, with negative symptoms (e.g., hot flashes, memory loss) frequently associated with positive experiences (e.g., new hobbies, new life-styles). However, even the most frequent negative symptom (memory loss) was reported only by 70%. The experience of a change represented by menopause was described both in terms of objective change (e.g., weight increase, hot flashes, memory loss), and of subjective change (e.g., character, feeling of not being attractive, new life-styles). Treatment with HRT seems to reduce the onset of hot flashes considerably. The occurrence of anxious-depressive states was comparable to that observed in other studies; it was not associated with HRT, but rather to losses (loss of desire, memory loss, insomnia). In conclusion, menopause represents a transitional moment in which physical and psychological changes are generally integrated by the persons experiencing them. In order to preserve a good quality of life in menopause, it seems relevant to check memory loss and stabilize the mood in persons who are most "at risk" of psychological disease.
