RESUMEN

OBJECTIVE: This study aimed to evaluate the association between daily spiritual experiences and allostatic load (AL) trajectories in midlife African American women. METHODS: A longitudinal analysis of public-use data from 727 African American women in the Study of Women's Health Across the Nation (SWAN) was performed. We included African American women who completed the Daily Spiritual Experiences Scale at SWAN visit 4 (2000-2001) and had AL data at three or more study visits over 7 years. AL was calculated at each visit using 10 biomarkers: systolic and diastolic blood pressure, body mass index, C-reactive protein, high-density lipoprotein cholesterol, total cholesterol, waist-to-hip ratio, fasting serum glucose, triglycerides, and dehydroepiandrosterone. Group-based trajectory modeling identified women with similar patterns of AL. We used multinomial logistic regression to estimate associations between daily spiritual experiences (some days or less, most days, daily, many times a day) and AL trajectories. FINDINGS: Our sample had a mean ± SD age of 49.9 ± 2.66 years, 47% were early perimenopausal, and 17% earned <$19,999 annually. The mean ± SD AL score was 2.52 ± 1.68. Three AL trajectories were identified: low (35.1%), moderate (44.7%), and high (20.2%). In age-adjusted models, women who reported daily comfort in religion and spirituality were less likely to follow a high AL trajectory (odds ratio, 0.41; 95% CI, 0.18-0.93); the association was attenuated when controlling for depressive symptoms (odds ratio, 0.48; 95% CI, 0.19-1.21). CONCLUSIONS: Findings from this study do not support an independent association between spirituality in African American women and AL trajectories in midlife. Studies with a larger sample and additional measures of spirituality are warranted in this population.

RESUMEN

BACKGROUND: The prevalence and intensity of menopausal symptoms differ depending on ethnicity, culture, and country. Epidemiological data from China are scarce. OBJECTIVE: To compare the prevalence and severity of menopausal symptoms in peri- and postmenopausal Chinese women. METHODS: This was a prospective two year cohort study that included all eligible women from 31 Chinese provinces attending our 'Menopause Clinic', the first official specialized center in China. Structured questionnaires containing seven domains with 41 items in total were used to assess the following menopausal symptoms using descriptive analysis: negative mood, cognitive symptoms, sleep disorder, vasomotor symptoms (VMS), urogenital symptoms, autonomic nervous disorder, and limb pain/paresthesia. RESULTS: A total of 4063 women with a mean age of 50.53 ± 6.57 (n = 2107 perimenopausal and 1956 postmenopausal) participated. All menopausal symptoms were more severe in postmenopausal women (p<.05). Independent of menopausal status, urogenital symptoms, often combined with sexual problems, were the most common complaints (in prevalence and severity), followed by sleep disorder, cognitive symptoms (especially hypomnesia), negative mood, autonomic nervous disorder, limb pain/paresthesia and, as the rarest complaint, VMS. CONCLUSIONS: Urogenital symptoms among midlife Chinese women are common, frequently also in combination with sexual dysfunction, although many do not often complain about these in the first place. Postmenopausal women presented more prevalent and severe menopausal symptoms. In contrast to Western countries, VMS are rare among our population. A multidisciplinary approach and use of hormonal and non-hormonal therapies should be considered for these women.

RESUMEN

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 Women's 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.

RESUMEN

Context: Menstrual cycle hormone patterns in women approaching menopause are inadequately studied. Objective: To describe day-to-day menstrual cycle hormones in women as they approach menopause from the Study of Women's Health Across the Nation Daily Hormone Study (DHS). Design: DHS enrollees collected daily urine for one entire menstrual cycle or up to 50 days, whichever came first, annually, up to the final menstrual period (FMP) or for up to 10 years. Setting: Seven sites across the United States. Participants: A total of 511 premenopausal or early perimenopausal women at enrollment, within 10 years before menopause. Intervention: Time-to-FMP measurement. Main Outcome Measures: Evidence of luteal activity (ELA), determined using objective algorithms. Menstrual cycle/segment length; whole cycle, and segment integrated urinary luteinizing hormone, follicle-stimulating hormone, estrone conjugates, and pregnanediol glucuronide (Pdg) for each year, organized around the FMP. Results: Mean menstrual cycle length was remarkably preserved at 26 to 27 days in ELA cycles; non-ELA cycles had greater variability. The percentage of cycles that were ELA remained high until 5 years before the FMP (87.9%); only 22.8% of cycles within 1 year of the FMP were ELA. Whole cycle hormones remained relatively stable up to 3 years before the FMP, when gonadotropins began to increase. Pdg excretion declined slowly with progress to the FMP, but Pdg patterns of ELA cycles remained distinguishable from non-ELA. Conclusions: Menstrual cycle hormone patterns in perimenopausal women resemble those of midreproductive-aged women until 5 years before menopause, and presumably ovulatory cycles retain a potentially fertile pattern up to the end of reproductive life.

RESUMEN

OBJECTIVE: This study aims to examine cross-sectional and longitudinal relations between dietary intake of isoflavones and bone mineral density (BMD) at the lumbar spine (LS) and femoral neck (FN) in black, white, Chinese, and Japanese women during the menopausal transition. METHODS: We tested whether tertiles of isoflavone intake were associated with baseline BMD when all women were premenopausal or early perimenopausal. To analyze whether isoflavone intake was associated with longitudinal BMD, we fitted piecewise linear models to repeated measurements of baseline-normalized LS or FN BMD as functions of time before or after the final menstrual period (FMP) date. RESULTS: Multiply adjusted mean FN BMD values of premenopausal Japanese women were monotonically positively related to isoflavone consumption (P for trend = 0.0003). Otherwise, no statistically significant baseline associations were observed. During the period of 1 year before the FMP through 5 years after the FMP, all participants lost LS and FN BMD. Loss was unrelated to isoflavone intake, except for Japanese women during the period of 1 year before the FMP to 2 years after the FMP: higher tertiles of isoflavone intake were associated with greater annual LS BMD loss rates (P for trend = 0.01) and FN loss rates (P for trend = 0.04). CONCLUSIONS: In Japanese women, higher isoflavone intake is associated with higher peak FN BMD but also with greater rates of LS and FN BMD loss during the menopausal transition. Results for the other racial/ethnic groups did not support a relation between dietary intake of isoflavones and either peak BMD or BMD loss during the menopausal transition.

RESUMEN

Perimenopausal obesity is a particular problem in Gulf Cooperation Council (GCC) countries. This study examined the culturally specific views of perimenopausal GCC women, and the causes and processes of midlife weight gain using a qualitative descriptive design with semistructured interviewing and content analysis. Constructs derived from the health belief model and Kleiman's explanatory model were used to identify and sort themes into conceptual categories. The findings of this study suggest that weight-management program plans targeting perimenopausal GCC women should take into consideration the multiple levels of factors and cultural influences on their behavior.

RESUMEN

In the past 20 years a large number of studies have been made in order to investigate what is associated with the severity ofperimenopausal symptoms and large interindividual differences in their manifestation. Apart from studies of the biological determinants of perimenopausal symptoms, they have also examined the contribution of various psychosocial factors in their occurrence and severity. Although menopausal symptoms are primarily considered to be a result of the sometimes intense hormonal fluctuations that are experienced during perimenopause, this does not necessarily exclude the role of psychosocial factors such as demographic characteristics, cultural or ethnic background, attitudes toward menopause, specific lifestyles and habits, specific previous life experiences and personality traits. A review of recent research findings and contributions of these psychosocial factors in the development of perimenopausal symptoms engaged will be presented in this work. Studies have clearly shown that certain psychosocial factors contribute to the occurrence and severity of symptoms or increased risk for perimenopausal symptoms, including the risk for major disturbances, such as clinical depression.

RESUMEN

BACKGROUND: It remains unclear whether gonadotropins or estrogen is responsible for early bone mineral density (BMD) decrease in Chinese women. METHODS: A cross-sectional study was conducted on 368 healthy adult women, aged 35-60 years. We measured BMD, calculated BMD decrease rates (BDRs) and assessed serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E(2)) levels. RESULTS: BDR was significantly negatively correlated with serum FSH (r=-0.429 to -0.622, all p=0.000) and LH (r=-0.359 to -0.526, all p=0.000). After adjustment for age and body mass index, the negative correlations of serum FSH and LH with BDR persisted, but there was no overall correlation between serum E(2) and BDR. Multiple linear stepwise regression analysis suggested that serum FSH is a negative determinant of BDR. Serum E(2) seems to be a positive determinant of BDR in a few parts of the skeleton. CONCLUSIONS: The decrease of BMD during the menopause is associated with FSH and LH levels, rather than E(2) in Chinese women.

RESUMEN

OBJECTIVE: to compare the climacteric symptoms between women from Mexico City and those from a Mayan community of the state of Yucatan. METHODS: In two groups of women, Group I) Spanish-speaking women from Mexico City and Group II) Maya speaking women from the state of Yucatan, 22 climacteric symptoms were evaluated using an analog visual scale (AVS) and the SUMEVA index. For statistical analysis t student test was used as well as Chi squared. RESULTS: 105 women, 50 of Mexico City and 55 of Maxcanu, Yucatan were studied. When comparing the groups no difference was found in age (52.5 +/- 6.5 vs 53.7 +/- 6.2, for group I and II respectively), the body mass index was significantly smaller in group I (29.7 +/- 5.0 vs 34.0 +/- 6.0, p < 0.001). In group 1, 15 of the 22 evaluated symptoms were significantly more intense in Group I, as well as the SUMEVA (Sum of Analog Visual Scale) index (71.4 +/- 44.5 vs 45.8 +/- 24.8, p < 0.001). The proportion of symptomatic women for each one of the symptoms was similar in both groups except for hair fall that was significantly greater in group I (74% vs 52%). CONCLUSION: climacteric symptoms were perceived with more intensity by Mexico City women, which allows suppose that western culture influence can be the responsible.

RESUMEN

AIM: To describe the clinical characteristics of female patients with gout, assess risk factors in this group and to identify any differences between pre- and postmenopausal women with this diagnosis. METHODS: We retrospectively reviewed the case records of all women who were seen with gout in a secondary care setting (inpatient and outpatient) at Counties Manukau District Health Board between July 2007 and July 2008. Demographic data, risk factors for gout and information on urate-lowering therapy was collected. A cut-off of less than and equal to 50 years was used to estimate pre-menopausal status. RESULTS: 122/509 (24%) of patients seen with gout were female. Fourteen female patients were less than or equal to 50 years of age; all of these patients were either Maori (43%) or of Pacific Island ethnicity (57%). Comorbidities in those =50 years old were renal impairment (78.6%), hypertension (64.3%), congestive heart failure (43%) and diabetes mellitus (42.9%). Comorbidities in women >50 years old were similar: hypertension (77%), renal impairment (70%), dyslipidemia (53%) and diabetes mellitus (50%). Ischemic heart disease was more common in older women (43% vs 7%), P<0.01. Mean body mass index (BMI) was significantly higher in the younger women (43.5 vs 33.1), P<0.01. Half of all the female patients were on diuretics, and medication used to lower uric acid level was prescribed in 35.7% of women less than and equal to 50 years of age, and 42.59% of women >50 years of age. CONCLUSION: Women who develop gout are more likely to be over the age of 50, have other comorbidities and be on diuretics. In comparison, younger women who develop gout have similar risk factors but tended to have a higher body mass index and are more likely to be of Maori or Pacific Island ethnicity.

RESUMEN

UNLABELLED: Bone mineral density does not explain race/ethnicity differences in hip fracture risk. In this study, we demonstrated that race/ethnicity differences in composite hip strength indices were consistent with documented race/ethnicity differences in hip fracture risk, suggesting that unlike bone density, the composite indices may represent ethnicity-independent measures of bone strength. INTRODUCTION: African-American and Asian women have lower risks of hip fracture than Caucasian women, but such racial/ethnic variation in hip fracture risk cannot be explained by bone mineral density (BMD). The composite indices of femoral neck strength integrate femoral neck and body size with BMD and predict hip fracture risk in Caucasian women. We hypothesize that unlike race/ethnic differences in BMD, race/ethnic differences in the composite strength indices would be consistent with race/ethnic differences in hip fracture risk. METHODS: We studied a community-based sample of Caucasian (n = 968), African-American (n = 512), Chinese (n = 221), and Japanese (n = 239) women, premenopausal or in early perimenopause, from the Study of Women's Health Across the Nation. RESULTS: Unadjusted indices were similar in Caucasian and African-American women but higher in Asian women. After adjusting for age, body mass index, and menopause status, all three minority groups had higher composite strength indices than Caucasian women. Foreign-born Japanese women had higher unadjusted and adjusted composite strength indices than US-born Japanese women, but such differences by nativity were not observed in Chinese women. CONCLUSION: We concluded that composite strength indices have the potential to explain racial/ethnic differences in hip fracture risk, suggesting that composite strength indices may represent ethnicity-independent measures of bone strength. This contention needs to be verified by further research on the fracture predictive ability of composite strength indices in multi-ethnic longitudinal cohorts.

RESUMEN

Reproductive health can be a reflection of overall health. It follows that abnormalities of reproductive milestones may be a manifestation of unhealthy aging. Since 1994, the Study of Women's Health Across the Nation (SWAN) has assessed how menopause and the process of that transition may affect future health. Themes have emerged from SWAN associating patterns of hormones and symptoms with metabolic status.The nature of these relationships vary as women traverse the menopause and ovarian hormone production ceases. This review describes these cross-cutting themes and their possible meaning for the health of the mid-life woman.

RESUMEN

The hormonal correlates of reproductive aging and the menopause transition reflect an initial loss of the follicle cohort, while a responsive ovary remains, and an eventual complete loss of follicle response, with persistent hypergonadotropic amenorrhea. The physiology of the process is described, along with key findings of relevant studies, with an emphasis on the Study of Women's Health Across the Nation. A clinical framework is provided to help clinicians to forecast the major milestones of the menopausal transition and to predict potential symptoms or disease.

RESUMEN

OBJECTIVE: Several randomized controlled trials (RCTs) have examined the role of soy isoflavones on cardiovascular risk factors in perimenopausal and postmenopausal women and have yielded inconsistent results. This meta-analysis aimed to assess the overall effect of soy isoflavones on glucose metabolism: fasting blood glucose, insulin, and insulin resistance. METHODS: We searched for all articles published in English and indexed in Medline from January 1990 to December 2009. We included RCTs for soy isoflavone supplementation in perimenopausal and postmenopausal women not taking hormone therapy, selecting non-Asian women only. The main outcomes were fasting blood glucose changes from baseline. RESULTS: We identified 10 eligible RCTs containing blood glucose data of 794 women. The main result was that soy isoflavones did not affect fasting blood glucose significantly. Under a random-effects model, the average difference in fasting blood glucose values between women assigned to isoflavones and women assigned to placebo was -2.16 mg/dL (95% CI, -5.21 to 0.89 mg/dL; P = 0.17). In genistein studies, the mean difference was -7.15 mg/dL (95% CI, -11.47 to -2.82). However, the effects on insulin and homeostasis model assessment insulin resistance were significant: -1.37 microIU/mL (95% CI, -1.92 to -0.81 microIU/mL) and -0.39 (95% CI, -0.65 to -0.14), respectively. Subgroup analyses did not show a significant effect of isoflavone dose, whereas isoflavone mixtures and genistein had a different effect on fasting blood glucose. CONCLUSIONS: This meta-analysis of RCTs showed that isoflavone use was not associated with a significant glycemia reduction in perimenopausal and postmenopausal non-Asian women. However, the few studies that reported insulin and homeostasis model assessment insulin resistance changes suggested that soy isoflavones and genistein alone had a beneficial effect on glucose metabolism.

RESUMEN

AIMS: This study aimed to examine differences in symptom clusters among women in midlife from different cultural origins and to identify sociodemographic, lifestyle, and health characteristics that could account for the differences between the cultural groups in symptom reporting. METHODS: Israeli women aged 45-64 were randomly selected according to age and population strata of three groups: long-term Jewish residents (LTR), Jewish immigrants from the former Soviet Union, and Arab women (mostly Israeli-born). Interviews were conducted with 540 LTR, 151 immigrants, and 123 Arab women. The survey instrument included the occurrence and rating of how bothersome to everyday function were 16 symptoms. Three outcome variables included hot flashes and two scales for mental and somatic symptoms extracted from exploratory factor analysis. RESULTS: Multivariate logistic regressions showed that immigrants and Arab women (compared to LTR) had a significantly lower risk of reporting hot flashes and mental and somatic symptoms. Menopausal status was related only to hot flashes. Low education and depression were associated with the three symptom scales, whereas nonhealthy lifestyle was related only to somatic symptoms. CONCLUSIONS: Our main finding is that cultural group is an independent predictor of each of the three menopausal symptom scales. A possible explanation for the lower reporting of symptoms among Arab and immigrant groups is that they differ from the LTR in level of acculturation and attitudes toward menopause. These findings support the proposition of a cultural factor in menopausal symptomatology that needs to be addressed by clinicians caring for women at midlife.

RESUMEN

OBJECTIVES: Whether age or menopause per se influences fat distribution remains controversial. This study aimed to investigate the change of body composition, particularly body fat distribution, in relation to menopausal transition in a 30-month prospective study of perimenopausal women. METHODS: A total of 438 community-based healthy women aged 44-55 years participated in the Hong Kong Perimenopausal Women Osteoporosis Study. Data were obtained at baseline, and at 9-, 18- and 30-month during the follow-up. Soft tissue measurements consisting of fat mass and lean muscle mass of the trunk and whole body were obtained by the dual energy X-ray absorptiometry. Percentage change of body measurements over the follow-up period was compared between women who remained premenopausal, those who went through menopausal transition, and those who were menopausal since baseline. RESULTS: A slight decrease in the lean mass but an increase in the total fat mass and trunk fat mass (TFM) over the follow-up period were noted. Multivariate linear regression analysis showed that age was negatively associated with an increase in central obesity. Adjusted for the important predictors--age, age of menarche and education level, menopausal status was a significant and independent predictor of the decrease in lean mass and the increase in percent of body fat, TFM and trunk-leg fat mass ratio. CONCLUSION: Our 30-month longitudinal study showed that menopause has an independent effect on an increase in fat mass, and an increase in central obesity in perimenopausal Chinese women.

RESUMEN

AIM: The aim of the study was to explore the menopausal symptom experience of White midlife women. BACKGROUND: Recent cross-cultural investigations have indicated important ethnic differences in menopausal symptoms and have challenged the universality of these symptoms. Currently available cultural knowledge on menopausal experience, however, is inadequate to guide appropriate and adequate care even for White women in the menopausal transition. METHOD: A cross-sectional qualitative online forum study was conducted in 2007 with 23 midlife women who self-identified as non-Hispanic Whites using convenience sampling. Seven topics related to menopausal symptom experience were used to guide the online forum for 6 months. The data were analysed using thematic analysis. RESULTS: The experiences of menopause caused women to redefine themselves within their busy daily life schedules. They were optimistic about their symptoms, and tried to laugh at the experience to boost their inner strength and motivate themselves to persevere. Many thought that both generational and life-style differences were much more important than ethnic differences in menopausal symptom experiences. In seeking assistance with the symptoms of menopause, women were not satisfied with the guidance of their physicians. CONCLUSION: Nurses need to listen carefully to what women themselves say about their own experiences with menopausal symptoms and avoid imposing predetermined symptom management strategies. Further studies of women's perceptions of life-style influences are needed to guide symptom management. In addition, studies of generational changes in menopausal symptom experience are needed.

RESUMEN

BACKGROUND: Bone mineral density and mammographic breast density are each associated with markers of lifetime estrogen exposure. The association between mammographic breast density and bone mineral density in early perimenopausal women is unknown. METHODS: We analyzed data from a cohort (n = 501) of premenopausal (no change in menstrual regularity) and early perimenopausal (decreased menstrual regularity in past 3 months) participants of African-American, Caucasian, Chinese, and Japanese ethnicity in the Study of Women's Health Across the Nation. Using multivariable linear regression, we examined the cross-sectional association between percent mammographic density and bone mineral density (BMD). RESULTS: Percent mammographic density was statistically significantly inversely associated with hip BMD and lumbar spine BMD after adjustment (body mass index, ethnicity, age, study site, parity, alcohol intake, cigarette smoking, physical activity, age at first childbirth) in early perimenopausal, but not premenopausal, women. In early perimenopausal women, every 0.1g/cm(2) greater hip BMD predicted a 2% lower percent mammographic density (95% confidence interval -37.0 to -0.6%, p = 0.04). CONCLUSION: Mammographic breast density is inversely associated with BMD in the perimenopausal participants of this community-based cohort. The biological underpinnings of these findings may reflect differential responsiveness of breast and bone mineral density to the steroid milieu.

RESUMEN

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 Women's 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.

RESUMEN

The transition into menopause is an experience that is unique to every woman. This experience can encompass anything from an occasional hot flash to complete and utter distress. Considerable attention is being paid to African-American women as they transition through menopause, but their use of symptom self-care strategies is an area that would benefit from further research. Findings from this study are part of a larger five-year study exploring biopsychosocial health and wellness among diverse midlife women. This report includes identification of symptom prevalence, symptom distress, and self-care strategies used by midlife African-American women during a six-month time period. Prevalent or severe symptoms included fatigue, headaches, cramps, night sweats, and depression. Most self-care strategies were "passive" strategies, such as 'faith," "think," "accept," or "value/believe/forgive self". It is recommended that health-care providers inquire about other symptoms that might accompany classic vasomotor menopausal symptoms and identify "active" self-care strategies that ameliorate specific symptoms.
