Objective: Although menopausal symptoms are an important issue for female workers, their association with work-related factors is not well studied. Here, we explored the association between work-related factors and menopausal symptoms in Japan. Methods: A cross-sectional study was conducted in 2023 among all 1465 female employees of a large Japanese company. Associations between occupational factors and moderate or severe menopausal symptoms, as measured by the Menopause Rating Scale (MRS), were examined using logistic regression analysis. Results: Several workplace-related factors were significantly associated with moderate or severe menopausal symptoms, including company support and the number of night shifts. A marginally significant association was also seen for commuting time. Conclusions: Workplacemenopause interventions for the factors identified in this study may satisfy unmet needs.

• Cassis polyphenol (CaP; 400 mg/d, 4 weeks) did not improve menopausal symptoms. • CaP (400 mg/d, 4 weeks) did not improve anxiety, quality of life, or sleep. • CaP (400 mg/d, 4 weeks) did not improve hot flashes (HF) or sweating. • HF and sweating improved in the CaP group during a 2-week post-intervention period. • CaP had limited effects on menopausal symptoms and may require longer intervention. Hormonal changes during the menopause transition may lead to vasomotor symptoms, including hot flashes (HFs) and neuropsychiatric symptoms such as anxiety and irritability. We hypothesized that the effects of cassis polyphenol (CaP) to improve microcirculation and vasorelaxation may alleviate menopausal symptoms. We performed a randomized, double-blind, parallel-group, placebo-controlled trial involving 59 healthy women (mean [standard deviation] age, 51.3 [4.3] years; body mass index, 20.8 [2.6] kg/m2). Participants experiencing subjective menopausal symptoms consumed CaP tablets (400 mg/d, CaP group) or placebo tablets (placebo group) for 4 weeks. Participants were evaluated using questionnaires at baseline, during the 4-week intervention period, and during a 2-week postinterventional observation period. The primary objective was to evaluate the effects of supplementation with CaP on HFs in healthy Japanese women with menopausal symptoms. Additional assessments included the modified Kupperman menopausal index, World Health Organization-5 Well-Being Index, World Health Organization quality-of-life 26-item index, State-Trait Anxiety Inventory (anxiety and trait components), and Oguri–Shirakawa–Azumi sleep inventory (middle-aged and elderly versions). During the 4-week intervention period, no significant between-group differences were detected in the HF frequency, HF score, sweating frequency, menopausal symptoms, quality of life, anxiety, or sleep. During the 2-week postintervention observational period, the HF score and sweating frequency were significantly decreased in the CaP group compared with the placebo group. These findings suggest that twice daily intake of CaP for 4 weeks does not alleviate menopause symptoms, but the improvement observed in the CaP intake group during the postintervention period warrants confirmation through further large-scale studies. CaP may alleviate menopausal symptoms by microcirculatory and antioxidant effects. A randomized, double-blind, parallel-group trial in 59 healthy women (mean ± standard deviation; age: 51.3 ± 4.3 years, BMI, 20.8 ± 2.6 kg/m2) revealed no significant differences in HF or sweating frequency, HF score, menopausal symptoms, quality of life, anxiety, or sleep between groups. In the 2-week observation after the intervention, HF scores and sweating frequency were significantly reduced in the CaP group. Abbreviations: BMI, body mass index; CaP, cassis polyphenols; HF, hot flash. [Display omitted] [ABSTRACT FROM AUTHOR]

This study aimed to assess the fertility knowledge of Japanese education undergraduates who plan to become schoolteachers and examine related factors. A cross-sectional questionnaire survey was conducted with 252 first-year education undergraduates at a Japanese university. The Cardiff Fertility Knowledge Scale (CFKS) was used to measure fertility knowledge, and other items inquiring about basic reproductive knowledge were included. We assessed the relationship between fertility knowledge and gender and the experience of future life planning, among other factors. We found that fertility knowledge varied. Participants possessed a relatively good knowledge of the relationships between fertility and female ageing, and smoking, but limited knowledge about the effect of sexually transmitted infections on fertility. Male participants answered more correctly than female participants (p < 0.01) regarding 'sperm production'; however, female respondents answered more accurately than male respondents (p < 0.01) regarding 'timing of menopause. In Japan, the national curriculum standard for upper secondary schools was revised in 2018, and fertility was added to the Health and Physical Education curriculum. The study results suggested that it is important to include fertility in a sex education teaching curriculum for education undergraduates to enable them to deliver fertility education as teachers in the future.

Aim: This study aimed to investigate the real‐world clinical practice of estrogen and progestogen prescriptions for menopausal women. Methods: Using a health care database in Japan, we conducted a cross‐sectional study on estrogen prescriptions and detailed analyses of newly initiated estrogens and concomitant prescriptions of progestogens. Data between January 2005 and December 2021 were analyzed. Results: In 2021, the proportion of women aged 45–49 years receiving estrogens was 25.8 [95% confidence interval (CI): 25.3, 26.3] per 1000 women, while it was 6.4 [95% CI: 6.0, 6.7] for those aged ≥60 years. The prescription of estrogens gradually increased in women aged 50–59 years after 2009. In women without a history of hysterectomy, transdermal estradiol was the primary form of estrogens prescribed for ≥180 days, in women aged <60 years. The proportion of transdermal estradiol gradually increased each year, whereas that of oral‐conjugated equine estrogens decreased. Among progestogen, the proportions of dydrogesterone and transdermal norethisterone acetate increased over time, while that of medroxyprogesterone acetate decreased. Approximately 30% of women prescribed estrogens for ≥180 days did not initiate progestogen concurrently. In women undergoing hysterectomy, progestogen was not initiated in >90% of cases, and transdermal estradiol was prescribed in approximately 80% of cases in 2021. Conclusions: This study reviewed the prescription of estrogens in menopausal women in Japan. A considerable number of women with a uterus are receiving estrogen therapy rather than estrogen‐progestogen therapy (EPT), despite the guidelines recommending the use of EPT in these women.

This study aimed to investigate the association between daily sleep duration of <7 hours and lower bone mineral density (BMD) using data from annual health check‐ups conducted in Japan between 2020 and 2022. Multivariate regression models were used, where BMD was the objective variable and daily sleep duration (<5 hours, 5 to <7 hours, 7 to <9 hours [reference], ≥9 hours) was the exposure variable adjusted for age, body mass index, physical activity, smoking status, and alcohol intake for men and women and further adjusted for menopausal status for women. The association between insomnia and BMD was also investigated. BMD was determined using calcaneal quantitative ultrasound and expressed as a percentage of the young adult mean (%YAM). In total, 896 men and 821 women were included. Median age was 54 years (interquartile range [IQR]: 46 to 64) for men and 55 years (IQR: 46 to 64) for women). Median BMD for men and women was 79%YAM (IQR: 71 to 89) and 75%YAM (IQR: 68 to 84), respectively. Approximately 80% of men and women slept <7 hours daily. Multivariate regression showed no association between sleep duration and BMD in men. However, women who slept 5 to <7 hours daily had significantly higher BMD by 3.9% compared with those who slept 7 to<9 hours (p = 0.004). No association between insomnia and BMD was found. Overall, a daily sleep duration of <7 hours was not independently associated with lower BMD compared to those who slept 7 to <9 hours in men and women. However, as there is evidence of both shorter and longer sleep durations being associated with an increased risk of adverse events, including cardiovascular events, our result needs to be interpreted with caution. © 2023 The Authors.

Midlife suicide among women has attracted increasing research attention. This study aimed to investigate the longitudinal association between menopause and suicidal ideation among middle-aged women. Our data were derived from the Tokyo Teen Cohort, a population-based survey of early adolescents (N = 3171) and their primary caregivers (typically, mothers) in Japan. A total of 2944 mothers (baseline mean age = 44.0 years) were included in the analysis. The baseline assessment in this study was performed at second-wave survey from July 2014 to January 2017. A follow-up assessment was conducted at fourth-wave survey from February 2019 to September 2021. Suicidal ideation at baseline and follow-up was assessed using the Suicidal Ideation subscale of the 28-item General Health Questionnaire. Menopausal stage was classified based on self-report at fourth-wave survey. Participants who started the perimenopausal stage after baseline were significantly more likely to have suicidal ideation at follow-up than those who did not have experienced menopausal transition yet. Participants with greater social support were less likely to report suicidal ideation at follow-up, even after adjusting for baseline suicidal ideation. This study was based on self-report regarding menopausal stage and only included mothers of adolescents from Japan. An exact length of time from the onset to the presence of suicidal ideation was unavailable. Women who have experienced the onset of menopausal transition presented an increased risk of suicidal ideation. Psychosocial interventions to increase social support may be beneficial in preventing mental health inequalities during menopausal transitions. • A growing number of studies has focused on suicide rates among middle-aged women. • We investigated the relation between menopause and suicidal ideation. • Participants at the perimenopausal stage were more likely to have suicidal ideation. • Greater social support was associated with decreased suicidal ideation at follow-up. • Psychosocial interventions to increase social support may be beneficial.

Aim: Hormone replacement therapy (HRT) relieves menopausal syndromes but concerns regarding certain cancer risks remain. This study aimed to investigate cancer risks in perimenopausal women using HRT. Methods: Using a health care database in Japan, we compared breast cancer and other cancer risks in perimenopausal women who started HRT between January 2011 and October 2021 at age 45–54 years with that of women who did not use HRT. Women in the control group were selected by 1:4 exact matching on birth year, and followed from the same index time as their counterparts. Results: Data from 12 207 women in the exposure group and 48 828 age‐matched women in the control group were analyzed. The median HRT duration was 16.1 (interquartile range, 9.9–28.0) months. Breast cancer risk was lower in the HRT group (adjusted hazard ratio [HR], 0.67; 95% confidence interval [CI], 0.54–0.82). When stratified by age, breast cancer risk was lower in the HRT group who started HRT at age 45–49 years (adjusted HR, 0.54; 95% CI, 0.40–0.72). Estrogen‐major HRT accounted for approximately one‐third of HRT and uterine corpus cancer risk was increased in estrogen‐major HRT (adjusted HR, 2.44; 95% CI, 1.56–3.81). Conclusions: Breast cancer risk in women starting HRT between 45 and 49 years is lower than that in the average population; this finding might be susceptible to unmeasured factors such as early menopause among HRT recipients. Unopposed estrogen therapy accounts for considerable proportion of HRT in Japan and it increases uterine corpus cancer. [ABSTRACT FROM AUTHOR]

Galactose and its metabolites, primarily derived from lactose, may have toxic effects on the ovary. We aimed to prospectively examine the associations of galactose and lactose intakes with the onset of natural menopause. The data of a population-based cohort study in a Japanese community (the Takayama study) initiated in 1992 were analysed, with follow-up data collected in 2002. Among the participants of the Takayama study, premenopausal women (n 3115) aged 35–56 years at baseline were included in this study. Dietary intake, including lactose and galactose was assessed only at baseline using a FFQ. The menopausal status and age at menopause were determined based on the participants' self-reports, and natural menopause was defined as the absence of menstruation for 12 months or more. Cox proportional hazards models were used to estimate the hazard ratios (HR) and 95 % CI. A total of 1790 women experienced natural menopause within the 10-year follow-up. Lactose and galactose intakes were associated with a later onset of natural menopause after adjusting for potential confounding factors and the HR (95 % CI) for the highest v. lowest quartile were 0·80 (0·69, 0·92) (P -trend = 0·001) in lactose and 0·86 (0·74, 1·00) in galactose (P -trend = 0·036), respectively. High intakes of lactose and galactose were associated with a later onset of natural menopause. Despite the presumed ovotoxicity effects, lactose and galactose intakes at usual levels may not be deleterious to the ovarian aging process among Japanese community-dwelling women.

Aim: This cross‐sectional study aimed to investigate the factors associated with dyspareunia in pre‐, peri‐, and postmenopausal Japanese women participating in the health and nutrition education program at a menopause clinic. Methods: First‐visit records of 1702 pre‐, peri‐, and postmenopausal Japanese women (aged 40–79 years) were analyzed. The relationship between severe dyspareunia and background characteristics was examined by multivariate logistic regression analysis. Results: The average age of the participants was 53.0 ± 6.3 years. The percentage of women who suffered from severe dyspareunia in the pre‐, peri‐, postmenopausal, and the hormone therapy receiving groups were 7.1%, 10.5%, 14.6%, and 7.8%, respectively. In the postmenopausal group, the percentage of women affected by severe dyspareunia was the highest between 2 and 5 years after menopause (18.8%), presumably owing to the gradual postmenopausal decline in the number of sexually active women. In sexually active postmenopausal women, body weight, body mass index (BMI), and body fat percentage (BF%) differed significantly among those who had severe dyspareunia (N = 119) and those who did not (N = 334). BMI and BF% were negatively associated with severe dyspareunia, even after adjustment for age and years since menopause (adjusted odds ratio [95% confidence interval]: BMI, 0.894 [0.825–0.964], p = 0.003; BF%, 0.947 [0.909–0.985], p = 0.006). Conclusions: BMI and BF% were negatively associated with dyspareunia in sexually active postmenopausal women. In addition to aging, the loss of body weight and fat could negatively impact intercourse in sexually active postmenopausal women. [ABSTRACT FROM AUTHOR]

Although changes in bone mineral density (BMD) are important indexes in osteoporosis treatment, no markers are available to predict them. Given the importance of assessing the therapeutic windows of antiresorptives, we explored potential biomarkers of bone remodeling in patients receiving treatment for osteopenia. Postmenopausal women with osteopenia (defined as a lumbar BMD T‐score <−1.0 standard deviation (SD) below that of a reference population but >−2.5 SD) were administered estradiol 1 mg/d and bazedoxifene 20 mg/d. After 3 months of treatment, we evaluated their ratio of serum bone‐specific tartrate‐resistant acid phosphatase to bone‐specific alkaline phosphatase (TRACP‐5b/BAP), which is widely used for evaluating bone turnover in postmenopausal patients with osteoporosis in Japan because their minimum significant changes are smaller than other bone turnover markers such as carboxy‐terminal collagen cross‐links (CTX) or N‐terminal propeptide of type I procollagen (P1NP) and thus, accurately reflect bone turnover. After 1 year of treatment, we assessed changes in lumbar BMD. The cut‐off TRACP‐5b/BAP scores for a ≤−2% decrease and ≥2% increase in lumbar spine BMD were 38.4 and 29.0, respectively. The TRACP‐5b/BAP scores were associated with significantly greater areas under the curve than the other evaluated parameters. These results suggest that the TRACP‐5b/BAP score after 3 months of osteopenia treatment can predict changes in lumbar BMD after 1 year of treatment. Moreover, a receiver operating characteristic curve analysis of TRACP‐5b/BAP scores after 3 months of antiresorptive therapy and percent changes in BMD at 1 year revealed that the TRACP‐5b/BAP score, as an index of the balance between bone resorption and formation markers, has the potential to serve as a modulator of the anabolic window reflective of bone remodeling. This study's findings also suggested a role for TRACP‐5b/BAP score as a predictor of a non‐response to antiresorptive therapy, thus offering health economic implications for osteoporosis treatment. © 2022 The Authors.

Our committee was founded in 2010 with the goal of improving women's health. This academic year we focused on the following five activities for the second consecutive year: cooperation between the department of pediatric surgery and the department of obstetrics and gynecology for the treatment of persistent cloaca and Mayer–Rokitansky–Küster–Hauser syndrome in Japan; assessment of the educational training of women's healthcare advisers; increasing screening for breast and cervical cancer; conducting the Nationwide Survey of Prescribing Practices for the Treatment of Menopausal Symptoms; and preventing osteoporosis in survivors of gynecologic cancer. The activities of each subcommittee are detailed below. This report is based on the Japanese version of the annual report (Acta Obst Gynaec Jpn 2021;73(6):684–699). [ABSTRACT FROM AUTHOR]

Background: Emerging evidence has shown that charged metabolites, such as amino acids, may play an important role in the pathogenesis of various metabolic disorders, many of which women in the postmenopausal period are at high risk of developing. This study examined the metabolic profile of middle-aged Japanese women to investigate alterations in charged metabolites induced by menopausal transition.Methods: The participants were 1193 female residents aged 40-60 at the baseline survey of the Tsuruoka Metabolomics Cohort Study. We investigated the cross-sectional association of menopausal status with 94 metabolomic biomarkers assayed in fasting plasma samples via capillary electrophoresis time-of-flight mass spectrometry using linear regression analysis.Results: Among the participants, 529 were premenopausal, 132 were in menopausal transition (MT), and 532 were postmenopausal. Significant differences were found in age, blood pressure, glucose and lipid levels, and smoking and drinking habits among the three groups. The concentrations of 5 metabolites in the MT group and 15 metabolites in the postmenopausal group were significantly higher than those in the premenopausal group after adjusting for confounding factors. When classified into pathways, these metabolites were related to the tricarboxylic cycle, urea cycle, and homocysteine metabolism, some of which are linked to arteriosclerosis.Conclusion: Multiple charged metabolites were associated with women's menopausal status, showing a gradual increase as women shifted from pre-, to peri-, to postmenopause. These findings might reflect the early changes behind the increased risk of dyslipidemia, diabetes, cardiovascular disease, and osteoporosis in later life. [ABSTRACT FROM AUTHOR]

Objective: The phase II STARLIGHT study was conducted to investigate the efficacy/safety of fezolinetant in Japanese women and identify the optimal dose for future evaluation., Method: Participants were perimenopausal/postmenopausal women aged ≥40 to ≤65 years from 36 centers in Japan seeking treatment/relief for vasomotor symptoms (VMS) associated with menopause. After screening, participants were randomized 1:1:1, stratified by menopausal status, to receive fezolinetant 15 or 30 mg or placebo orally once daily for 12 weeks. Participants completed a daily VMS diary. The primary endpoint was mean change in frequency of VMS of any severity from baseline to week 8. Secondary endpoints included mean change in VMS frequency from baseline each week up to week 12 and frequency/severity of adverse events., Results: A total of 147 participants were randomized (placebo, n  = 47; fezolinetant 15 mg, n  = 53; fezolinetant 30 mg, n  = 47). Fezolinetant 15 and 30 mg demonstrated statistically significant reductions in mean VMS frequency at week 8 versus placebo. Least-squares mean estimates of mean change in frequency of VMS from baseline to week 8 were -7.04 for fezolinetant 15mg, -6.31 for fezolinetant 30mg, and -4.55 for placebo. The difference in least-squares mean estimates was -2.50 (95% CI: -4.03, -0.96), p  = 0.002 for fezolinetant 15mg and placebo, and was -1.76 (95% confidence interval [CI]: -3.35, -0.17), p  = 0.030 for fezolinetant 30mg and placebo. Reductions from baseline in mean VMS frequency versus placebo were seen after week 1 of treatment, maintained throughout 12 weeks. Fezolinetant was well tolerated, with no safety signals of concern for either dose to week 12., Conclusion: Oral fezolinetant at once-daily doses of 15 or 30 mg was efficacious and well tolerated for treatment of mild, moderate and severe VMS associated with menopause in this Japanese study.

We investigated the relationship between shift work and excessive daytime sleepiness (EDS) among participants in the Japan Nurses' Health Study (JNHS). Responses of 9,728 female nurses to the 6th follow-up questionnaire were cross-sectionally analyzed. EDS was defined as an Epworth Sleepiness Scale score ≥11. EDS-associated factors were evaluated using Poisson regression analysis after adjustment for multiple confounders. Of the participants (mean age, 52.2 ± 8.0 yr), 28.7% were engaged in shift work, and the overall prevalence of EDS was 24.6%. EDS-associated factors were investigated separately in women aged <40 yr (n=250), 40-59 yr (n=7,467), and ≥60 yr (n=2,011). Current engagement in shift work (prevalence ratio: 1.92 [95% confidence interval: 1.20-3.06], compared with no experience of shift work) and obesity (2.08 [1.11-3.88] for BMI ≥30 and 1.39 [1.02-1.90] for BMI of 25.0-30.0, compared with BMI of 18.5-25.0) showed an independent association with EDS in women aged ≥60 yr. The effect of shift work on EDS in female nurses differed by age, as shift work and obesity contributed to EDS only in older participants. Shift work should be assigned after full consideration of age, sleep, and health status to minimize medical errors.

Objectives: Various oral symptoms, including xerostomia and burning mouth syndrome, may occur in menopausal women. These symptoms reduce quality of life (QOL). However, the actual condition of xerostomia after menopause is not clear. The purpose of this study was to reveal the factors associated with xerostomia in perimenopausal women. Methods: Participants included 118 outpatients (mean age, 49.9 ± 3.2 years; range, 45–55 years) at a department of gynecology in Japan. Information was collected concerning age, medical history, medications, menstrual status, and history of treatment for climacteric symptoms. Oral symptoms, including xerostomia were evaluated with a 3‐point scale. The climacteric symptom checklist for Japanese women and 36‐Item Short‐Form Health were used to evaluate climacteric symptoms and QOL, respectively. In addition, the volume of unstimulated saliva, oral moisture, salivary α‐amylase, chromogranin A, and 17‐β estradiol were measured. Results: Higher age, the total number of medications, psychotropic drug, hormone replacement therapy, treatment for climacteric symptoms, sticky mouth, burning sensation of tongue, dryness of nose and 14 of the 21 climacteric symptoms significantly affected xerostomia. In addition, treatment for climacteric symptoms, fall asleep but often awake at night, headaches and dryness of nose were significantly associated with xerostomia. In conclusion, xerostomia is closely associated to factors such as treatment for climacteric symptoms and certain menopausal symptoms, and it may be related to QOL in perimenopausal women.

Aim: To assess prevalence and characteristics of vasomotor symptoms in community‐dwelling Japanese women. Methods: These were cross‐sectional analyses using data from the National Institute for Longevity Sciences‐Longitudinal Study of Aging. The main outcome measures were prevalence and severity of hot flashes and sweating. Associations between hot flashes/sweating (slight, moderate, or severe vs none) and sleep problems were explored using logistic regression, with and without adjustment for age, daily physical activity, and number of urinations/night. Associations between hot flashes/sweating and sleep problems, depressive symptoms, and dietary variables were explored in logistic regression models or general linear models. Results: A total of 1152 women between 40 and 91 years of age were enrolled. Hot flashes were reported by 24.5% of participants; with prevalence and severity highest in those 50–54 years or 2–5 years postmenopause. Sleep problems were reported 15 percentage points more frequently by women who reported hot flashes than by those without hot flashes. Adjusted odds ratios [95% CI] for difficulty in falling asleep and difficulty in sleeping through were 2.09 [1.565–2.796] and 2.07 [1.549–2.763]), respectively. Also, hot flashes were associated with higher risk of depressive symptoms (adjusted odds ratio [95% CI]: 2.99 [2.07–4.32]) and lower life satisfaction, self‐esteem, and self‐rated health status. A similar pattern was observed in women with and without sweating. No associations were found between hot flashes and dietary factors. Conclusions: Clear associations were found between hot flashes and sleeping problems, even after adjusting for potential confounding factors. Women who reported hot flashes also reported worse mental and physical health than those who did not report hot flashes. [ABSTRACT FROM AUTHOR]

Objective: The Japan Society of Obstetrics and Gynecology conducted a retrospective multiinstitutional survey of patients who underwent cervical conization in Japan. This study aimed to determine the predictive factors for positive surgical margins in cervical intraepithelial neoplasia grade 3 (CIN 3) patients after therapeutic cervical conization and those for positive margins in patients who did not experience recurrence and did not undergo additional treatment. Methods: In 2009 and 2013, 14,832 patients underwent cervical conization at 205 institutions in Japan. Of these, 8856 patients who underwent therapeutic conization fulfilled the inclusion criteria. Their histologic findings and clinical outcomes were evaluated based on standard statistical procedures and clinical and demographic characteristics. Results: Negative and positive margins were observed in 7,585 and 1,271 (14.4%) patients, respectively. The predictors of positive margins were menopausal status (p<0.001), loop electrosurgical excision procedure (p<0.001), and Shimodaira-Taniguchi (S-T) conization (p<0.001). Of 1,271 patients with positive margins, 1,060 underwent no additional treatment; among those 1,060 patients, 129 (12.2%) experienced recurrence. The predictors of positive margins in patients who did not undergo additional treatment and did not experience recurrence were age, parity, gravidity, S-T conization, and laser scalpel conization. Conclusion: Menopausal status and treatment procedures were associated with positive margins after therapeutic conization of CIN 3. It is important to understand the characteristics of treatment procedures and select an appropriate procedure for each case. For elderly or menopausal patients with positive margins, immediate additional treatment is recommended. [ABSTRACT FROM AUTHOR]

The aim of this study was to monitor the development of drug-resistant bacteria isolated from acute uncomplicated cystitis (AUC) and to evaluate methodology of the survey conducted by collecting only clinical data. We enrolled female patients at least 16 years of age diagnosed with AUC in 2018. Patient information including age, menopausal status, and results of bacteriological examination were collected and analyzed regardless of bacterial identification, antimicrobial susceptibility testing or extended-spectrum β-lactamase (ESBL) detection method. A total of 847 eligible cases were collected. Escherichia coli (E. coli) was the most frequently isolated bacterial species at about 70%, with proportions of fluoroquinolone-resistant E. coli (QREC) and ESBL-producing E. coli isolates at 15.6% and 9.5% of all E. coli isolates, respectively. The proportion of Staphylococcus saprophyticus (S. saprophyticus) was significantly higher in premenopausal women. Regarding the drug susceptibility of E. coli, isolates from Eastern Japan had significantly higher susceptibility to cefazolin, cefotiam and cefpodoxime and lower susceptibility to levofloxacin in postmenopausal women. ESBL-producing E. coli isolates had a high susceptibility to tazobactam-piperacillin, cefmetazole, carbapenems, aminoglycosides, and fosfomycin. In S. saprophyticus , the susceptibility to β-lactams including carbapenems was 40–60%. The proportions of QREC and ESBL-producing E. coli were increasing trends and lower susceptibility to LVFX in postmenopausal women was observed. Such surveillance, consisting of the collecting only clinical data, could be conducted easily and inexpensively. It is expected to be continuously performed as an alternative survey to conventional one collecting bacterial strains. [ABSTRACT FROM AUTHOR]

Based on longitudinal mixed methods ethnographic research conducted in China from the mid-1990s to 2018, this article argues that Chinese lay language use divides what Americans and Canadians refer to as "menopause" into two distinct though overlapping concepts of the narrow juejing or end of menstruation and the broader non-gender-specific gengnianqi or "transition between middle and old age." While comparison with research done by Lock in Japan shows that Japanese language uses a similar set of two overlapping yet distinct terms called heikei and könenki, there are important differences between Chinese and Japanese views and experiences of female midlife amidst the similarities. While views and experiences of juejing in China are very similar to notions of heikei in Japan, gengnianqi is quite different from könenki. Like in Japan, the end of menstruation tends to be welcomed by women in China. Also like in Japan, midlife women in China had a lower prevalence of hot flashes than that found in the US and Canada. Also similar to Japan, Chinese women rarely associate hot flashes with embarrassment. However, unlike in the Japanese sample, the Chinese women reported a higher rate of irritability than even the American and Canadian samples. Contrasting with könenki, which is primarly associated with bodily aches and self-restraint in Japan, gengnianqi is commonly viewed as a time of vulnerability to irritable outbursts which must be allowed, though managed carefully. Overall, I show how menopause and midlife aging as concepts and as lived experiences are subject to variation related to differences in language, cultural ideas and practices, local biologies, and culturally-mediated generational experiences of historical change.

Objective: This cross-sectional study investigated chilliness, which is the most prevalent sexual-vasomotor symptom in middle-aged Japanese women.Methods: First-visit records of 475 Japanese women (age 40-65 years) enrolled in the health and nutrition education program at a menopause clinic were analyzed. Chilliness was estimated based on responses to the Menopausal Symptom Scale. Effects of age, menopausal status, body composition, cardiovascular parameters, resting energy expenditure, physical fitness, menopausal symptoms, lifestyle, and estimated daily intake of nutrients were assessed using a multivariate logistic regression analysis.Results: Severe chilliness was found in 28.4% of women. It was not related to age, menopausal status, body mass index, or body fat percentage. The anxiety subscale score of the Hospital Anxiety and Depression Scale was the sole background characteristic independently associated with severe chilliness (adjusted odds ratio, 1.09; 95% confidence interval, 1.04-1.15 per point). Daily intakes of vitamin D and n-3 fatty acids were significantly lower in women with severe chilliness. Daily intake of n-3 fatty acids was negatively associated with severe chilliness after adjustment (odds ratio, 0.54; 95% confidence interval, 0.29-0.95 per g/1000 kcal intake).Conclusions: Chilliness is associated with anxiety and low intake of n-3 fatty acids.

The number of long‐term breast cancer survivors with a risk of late recurrence is increasing. Hormone‐receptor‐positive patients have greater risks of late recurrence. Although several studies demonstrated that extended adjuvant endocrine therapy reduces the incidence of late recurrence, it remains unclear which hormone‐receptor‐positive patients have greater risks of late recurrence. Hormone‐receptor‐positive breast cancer patients were retrospectively selected from the prospective database of primary breast cancer patients treated at Keio University Hospital from January 1989 to December 2003. Late recurrence was defined as initial recurrence after 5 years from the initial surgery. We evaluated the clinicopathologic features of breast cancer patients with late recurrence. At a median follow‐up of 10.9 years (range, 5.1‐23.8), 371 patients had no recurrence, 90 had early recurrence (within 5 years), and 83 had late recurrence. Multivariate analysis revealed that >4 involved lymph nodes were significant risk factors for late recurrence (P <.001), whereas 1‐3 positive nodes were not. Endocrine therapy significantly reduced the incidence of late recurrence (P <.001). After menopause, adjuvant therapy with aromatase inhibitors resulted in longer disease‐free survival than tamoxifen (10‐year disease‐free survival: 97.6% vs 89.7%, P =.0955). High nodal involvement was significantly correlated with late recurrence in hormone‐receptor‐positive breast cancer patients. Hormone‐receptor‐positive breast cancer patients who receive adjuvant endocrine therapy with tamoxifen alone might be candidates for extended endocrine therapy. [ABSTRACT FROM AUTHOR]

Summary: This large-scale population-based cohort study in Japan was conducted to clarify the effects of menstrual and reproductive factors on the risk of later-life vertebral fractures in women. Significant associations were seen for later menarche, irregular menstruation, and shorter reproductive years, corresponding to the effect of reproductive hormonal disturbance on bone metabolism.Introduction: This study investigated the association between menstrual and reproductive factors and the risk of later-life vertebral fractures in women.Methods: Participants were 43,652 women aged 40-69 years who were followed in the 10-year survey of the Japan Public Health Center-based prospective (JPHC) study. Menstrual/reproductive factors were as follows: age at menarche and menopause, menstrual regularity and cycle length, natural or surgical menopause, years since menopause, reproductive years, parity, age at first birth, number of births, breastfeeding, and female hormone use. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by logistic regression analysis with adjustment for well-known fracture risk factors and menstrual/reproductive factors.Results: During the 10-year period, 250 women reported first onset of vertebral fractures. Menarche at ≥16 years [OR (95% CI) = 2.08 (1.24-3.48)] compared to ≤ 13 years and irregular menstruation [1.42 (1.01-2.00)] compared to regular menstruation showed significantly higher adjusted ORs. Longer reproductive years had significant inverse association [0.96 (0.92-0.99)] in menopausal women. Women with both menarche ≥ 15 years and irregular menstruation had higher adjusted ORs (95% CI) [2.37 (1.51-3.73) in all women, 2.25 (1.35-3.76) in menopausal women] compared to women without these, and both factors had significant interaction, particularly in menopausal women (additive p = 0.025, multiplicative p = 0.0499).Conclusions: Menstrual and reproductive factors, corresponding to the effect of reproductive hormonal disturbance on bone metabolism, might affect the risk of later-life vertebral fractures.

In recent decades, surgical techniques, new anticancer drugs' development, and radiation equipment have led to continuous improvements in cancer survival rates and quality of life of cancer survivors (CSs). While 61.0% of gynecological cancer survivors (GCS) in Japan belonged to a working‐age group (20–64 years old), the number of working GCS within the working‐age population has increased. In Japan, it seems that there has been more interest in striking a balance between cancer treatment and work, especially since 2016 when the Cancer Control Act was amended and national guidelines for working CSs were published. Maintaining employment after gynecological cancer diagnosis remains an important issue for not only GCS and their families but also employers and society. GCS suffered from various symptoms including cancer‐related fatigue, pain, menopausal symptoms, lymphedema, and psychological distress, which made maintaining employment difficult for them. Full return to work (RTW) rate at 365 days after the initial days of sick leave among was 77.6% and median time to full RTW among GCSs was 172 days. Five‐year work continuance rate after RTW among GCSs was 63.4%. It is better for gynecologists to write a certificate for workplace in words of not "symptoms," but "caseness words (such as, workable as long as it is sedentary or clerical work. Partial RTW (4‐h work, 6‐h work) might be desirable for a while after RTW," in order to support GCSs' maintaining employment. [ABSTRACT FROM AUTHOR]

Abstract: Hormone replacement therapy (HRT) plays a large part in maintaining and improving the quality of life (QOL) of postmenopausal women. Despite this obvious role, the use of HRT has stagnated in Japan as well as the United States, since the interim report of the HRT trial of Women's Health Initiative study was published in 2002. The Japan Society of Obstetrics and Gynecology and Japan Society for Menopause and Women's Health formulated the Guidelines for Hormone Replacement Therapy in 2009, which was subsequently revised in 2012, with the aim of organizing perceptions about HRT and allowing people to provide or receive HRT with a sense of security. Later on, in light of changes in indications for HRT and attitudes toward its impact on cancer risks, amendments were made again in 2017. With the establishment of the 2017 guidelines, practitioners in Japan are able to address various issues related to HRT with more appropriate judgment. Moreover, the practice of reliable, safe and effective HRT is expected to promote further efforts toward improvement or maintenance of QOL in patients. [ABSTRACT FROM AUTHOR]

We conducted and evaluated a coaching intervention aimed at encouraging menopausal women’s engagement in goal-oriented actions, self-efficacy enhancement, menopausal symptom alleviation, and quality of life improvement. The study was a randomized controlled trial comprising women aged 40–60 who were not receiving hormone therapy. The intervention group received leaflets and three monthly coaching sessions. Instruments included the Simplified Menopausal Index, Medical Outcome Study 36-Item Short Form Health Survey, and goal achievement scale. Participants were measured preintervention, immediately postintervention, and three months postintervention. A 3-month coaching intervention to enhance menopausal women’s health increased their self-efficacy. This effect was not maintained 3 months postintervention. [ABSTRACT FROM PUBLISHER]

Objectives: The prevalence of cardiovascular diseases increases with age, especially in postmenopausal women. In this study, we investigated the dietary patterns associated with body mass and body fat in Japanese middle-aged women.Study Design: Cross-sectional.Main Outcome Measures: This study used baseline data collected in a previous study in 88 women aged 40-60 years. Participants were assessed for age, menopausal status, lifestyle factors, body composition, and dietary habits using a brief-type self-administered diet history questionnaire, which provides information on the amounts of nearly 100 nutritional factors consumed during the previous month. Classifying body mass index (BMI) as low (≤22kg/m2) or high (>22kg/m2) and percentage body fat as low (≤25%) or high (>25%), we sought to identify the nutritional factors associated with BMI and percentage body fat.Results: Consumption differences between high/low BMI and high/low body fat percentage groups were not significant for any nutritional factors except cryptoxanthin. Multiple logistic regression analysis adjusting for age, menopausal status, working, exercise, and smoking revealed that higher cryptoxanthin intake was associated with low BMI (adjusted odds ratio, 1.22 per 100μg/day increase of cryptoxanthin intake; 95% confidence interval, 1.01-1.52) and low body fat percentage (adjusted odds ratio, 1.36 per 100μg/day increase of cryptoxanthin intake; 95% confidence interval, 1.13-1.70).Conclusions: Higher intake of cryptoxanthin was shown to be related to low body mass and body fat in Japanese middle-aged women.

Objectives: Little is known about what type of women use hormone replacement therapy (HRT) in Japan. Based on the Japan Nurses' Health Study (JNHS), a large population cohort study, we determined the characteristics of HRT users by comparing the characteristics of new HRT users and the characteristics of women who did not use HRT during a 10-year follow-up period., Study Design: Of the 15,019 JNHS participants, 4886 women reported an experience of menopausal transition during the 10-year follow-up period., Main Outcome Measurement: Characteristics of new HRT users., Results: The proportion of HRT users during the 10-year period was 8.5 %. Advanced age at menopause was significantly associated with a low rate of use of HRT. Past use of oral contraceptives, dysmenorrhea with disturbance in daily life and vasomotor symptoms were significantly associated with a high rate of use of HRT. The occupations of public health nurse and midwife and a history of bilateral oophorectomy were also significantly associated with a high rate of use of HRT., Conclusions: We determined the characteristics of new HRT users among middle-aged women during a 10-year follow-up period. Women who had sufficient knowledge about endocrinological hormones and women who had less reluctance to visit doctors for gynecological problems were likely to use HRT., Competing Interests: Declaration of competing interest The authors declare that they have no competing interest., (Copyright © 2023 Elsevier B.V.

Objective: This study aimed to investigate the prevalence of genitourinary syndrome of menopause (GSM) in Japan using the Japanese translation of the Vulvovaginal Symptoms Questionnaire (VSQ) with online survey. In addition, we examined the relationship between sexual activity and GSM symptoms., Methods: An online survey on GSM was conducted with 4,134 women aged 40 to 79 years, who were registered in an online survey company. Several questionnaires with Japanese translations of linguistic validity were used in this study. GSM was defined as a condition in women older than 40 years with vulvovaginal symptoms on the VSQ., Results: The percentage of postmenopausal women 40 years and older was 69.6%. The percentage of women with sexual activity was 22%. The prevalence of GSM with vulvovaginal symptoms was 11.6%, and 31.7% in sexually active women. The prevalence of GSM was associated with age and was significantly lower in the 70s age group than in other age groups. Vulvar hurting and dryness were both age-related only in the sexual activity group, with a statistically significantly higher prevalence in the 70s group than in the 40s group. The prevalence of vulvar dryness during sexual activity was significantly lower in the 40s age group., Conclusions: An online epidemiological survey of GSM was conducted for the first time in Japan using the linguistically validated Japanese translation of the VSQ. The prevalence of GSM with genital or sexual symptoms was 11.6% in Japanese women 40 years and older, and 31.7% in sexually active women., Competing Interests: Financial disclosure/conflicts of interest: None reported., (Copyright © 2023 by The North American Menopause Society.)

Objectives: The International Collaboration for a Life Course Approach to Reproductive Health and Chronic Disease Events (InterLACE) project is a global research collaboration that aims to advance understanding of women's reproductive health in relation to chronic disease risk by pooling individual participant data from several cohort and cross-sectional studies. The aim of this paper is to describe the characteristics of contributing studies and to present the distribution of demographic and reproductive factors and chronic disease outcomes in InterLACE.Study Design: InterLACE is an individual-level pooled study of 20 observational studies (12 of which are longitudinal) from ten countries. Variables were harmonized across studies to create a new and systematic synthesis of life-course data.Main Outcome Measures: Harmonized data were derived in three domains: 1) socio-demographic and lifestyle factors, 2) female reproductive characteristics, and 3) chronic disease outcomes (cardiovascular disease (CVD) and diabetes).Results: InterLACE pooled data from 229,054 mid-aged women. Overall, 76% of the women were Caucasian and 22% Japanese; other ethnicities (of 300 or more participants) included Hispanic/Latin American (0.2%), Chinese (0.2%), Middle Eastern (0.3%), African/black (0.5%), and Other (1.0%). The median age at baseline was 47 years (Inter-quartile range (IQR): 41-53), and that at the last follow-up was 56 years (IQR: 48-64). Regarding reproductive characteristics, half of the women (49.8%) had their first menstruation (menarche) at 12-13 years of age. The distribution of menopausal status and the prevalence of chronic disease varied considerably among studies. At baseline, most women (57%) were pre- or peri-menopausal, 20% reported a natural menopause (range 0.8-55.6%) and the remainder had surgery or were taking hormones. By the end of follow-up, the prevalence rates of CVD and diabetes were 7.2% (range 0.9-24.6%) and 5.1% (range 1.3-13.2%), respectively.Conclusions: The scale and heterogeneity of InterLACE data provide an opportunity to strengthen evidence concerning the relationships between reproductive health through life and subsequent risks of chronic disease, including cross-cultural comparisons.

Objectives: This study proposed a method for assessing menopause-specific health literacy (knowledge and beliefs about menopausal symptoms which aid their recognition, assessment, and management) using a vignette methodology.Study Design: A cross-sectional web-based survey was conducted in September 2015 among Japanese women aged 30-59 years. Of 1236 women surveyed, 1196 eligible participants who were not under treatment for menopausal symptoms were included.Main Outcome Measures: Participants were presented with a vignette describing a woman with menopausal symptoms and were then asked a series of questions to assess their recognition of menopausal symptoms, attitude, subjective norm, perceived behavior control, availability, and intention to seek medical care if they themselves had the problems described in the vignette.Results: The majority (87%) of participants correctly labelled the vignette as menopausal symptoms and 60% expressed an intention to seek medical care if they had the symptoms presented. Logistic regression showed that attitude, subjective norm, and perceived behavior control were significant predictors of the intention to seek medical care. A structural equation model depicting these relationships with intention to seek medical care revealed acceptable fit indices: goodness of fit index (GFI)=0.948, adjusted goodness of fit index (AGFI)=0.913, comparative fit index (CFI)=0.883, and root mean square error of approximation (RMSEA)=0.089. Subjective norm had the greatest direct effect on intention to seek medical care.Conclusions: The assessment of menopause-specific health literacy may be useful for understanding why women hesitate to seek medical care for menopausal symptoms and for developing interventions to improve the coping behaviors of women with menopausal symptoms.

Aims and objectives To describe what effects low back pain has on the daily lives of female family caregivers and to elucidate the caregiving factors associated with its development. Background Low back pain is a common musculoskeletal symptom in caregivers. However, few detailed studies have examined the association of low back pain with the daily lives of female family caregivers or which caregiving activities lead to their low back pain. The elucidation of these issues will contribute to the prevention and treatment of their low back pain. Design A cross-sectional study. Methods Japanese female family caregivers ( n = 156) completed a self-administered questionnaire assessing lifestyle, health status, daily activity and caregiving situation. Correlation analysis measured the association between low back pain and daily activity. Logistic regression analysis identified care activities related to low back pain. Results Thirty-five (22·4%) participants almost always experienced low back pain. The severity of low back pain was significantly and positively associated with difficulty in daily activities, especially bending and extending the lower back. As for care situation factors and caregiving activities, night care, assisting the family member to stand up and to lie down, dealing with problem behaviours, and taking medication were associated with the development of low back pain. After reclassifying the respective caregiving activities, those involving body repositioning and those mainly performed in a static position showed significant associations. Conclusions Low back pain in female family caregivers negatively affects their daily activities and certain caregiving activities are involved in the development of low back pain. Relevance to clinical practice Clinical nurses understand the situation of female caregivers and could prevent the development of low back pain with early intervention by providing adequate strategies to alleviate the burden of identified care activities related to low back pain.

Purpose: Many studies have demonstrated the effectiveness of isoflavones on menopausal symptoms; however, these mostly used high dosages. Because high-dose isoflavone may result in endometrial hyperplasia, we investigated whether low-dose isoflavone aglycone alleviates menopausal symptoms similarly to high dosages.Methods: We conducted a randomized, double-blind, placebo-controlled study in 90 healthy women aged 40-60 years who had at least one menopausal symptom on the Menopausal Symptom Scale (MSS). The participants were randomized to receive active tablets containing ultralow-dose (12.5 mg/day; n = 30) or low-dose (25 mg/day; n = 30) isoflavone aglycone, or placebo (n = 30) tablets, for 8 weeks. Their menopausal symptoms were evaluated using MSS, Hospital Anxiety and Depression Scale (HADS), and Athens Insomnia Scale (AIS) before, and 4 and 8 weeks after treatment.Results: Eighty-seven women (97 %) completed the 8-week treatment. In the low-dose group, significant improvement was observed from baseline, in the following parameters: (1) HADS-depression subscale score, (2) AIS score, (3) MSS-somatic symptom score after 4 and 8 weeks of treatment, and (4) MSS-vasomotor symptom score after 8 weeks of treatment. The changes in scores on HADS-depression subscale and AIS from baseline to 8 weeks were significantly higher in the low-dose group than in the placebo group.Conclusions: Low-dose (25 mg/day) isoflavone aglycone significantly alleviated symptoms of depression and insomnia in Japanese middle-aged women.

Objective: We examined the change in circulating sclerostin level during the menopausal transition and we investigated the associations of sclerositin with hormones and bone turnover markers according to each menopausal stage in cross-sectional and longitudinal studies. Methods: We conducted a cross-sectional study in 200 healthy Japanese women and divided them into 4 stages (reproductive, menopausal transition, early postmenopause and late postmenopause) by menstrual regularity, follicle-stimulating hormone level and years since menopause. Serum levels of sclerostin, bone turnover markers and reproductive hormones were measured. In addition, we examined changes in sclerostin level from the reproductive stage to menopausal transition and from menopausal transition to early postmenopause in a longitudinal study. Results: In the cross-sectional study, sclerostin level gradually increased with progression of menopausal stages and showed a significant change during the menopausal transition. Sclerostin levels significantly increased from the reproductive stage to menopausal transition and from menopausal transition to early postmenopause in the longitudinal study. A negative correlation of sclerostin with estradiol was found in early postmenopause. Sclerostin levels were negatively correlated with bone-specific alkaline phosphatase levels in the reproductive stage and menopausal transition and with tartrate-resistant acid phosphatase-5b in menopausal transition. Conclusion: The change in sclerostin has already occurred in the early stage of menopausal transition and sclerostin level increases with progression of menopausal stages. Elevated sclerostin levels during the menopausal transition may be involved in relative decline in bone formation against increase in bone resorption. [ABSTRACT FROM AUTHOR]

Summary: Previous studies on the association between uric acid and bone mineral density yielded conflicting results. In this study, we demonstrated positive association between uric acid and lumbar spine bone mineral density in peri- and postmenopausal Japanese women. Further research is needed to elucidate the underlying mechanism. Introduction: Oxidative stress has been implicated in the pathogenesis of osteoporosis. Uric acid, a potent antioxidant substance, has been associated with bone mineral density but previous studies have yielded conflicting results. The objective of the study was to examine the association between serum uric acid and lumbar spine bone mineral density (BMD). Methods: This was a retrospective analysis of medical records of 615 women, aged 45-75 years, who had lumbar spine BMD measurement by dual-energy X-ray absorptiometry as a part of health checkup from August 2011 to July 2012. Results: Mean serum uric acid level was 4.7 mg/dL. Serum uric acid level was positively and significantly associated with lumbar spine BMD independent of age, body mass index, smoking, drinking, physical activity, years after menopause, diabetes mellitus, hypertension, serum calcium, estimated glomerular filtration rate, plasma C-reactive protein, and serum alkaline phosphatase (standardized beta = 0.078, p = 0.049). Uric acid rapidly increased until the age of 60 years, and then decelerated but continued to increase thereafter. The association between lumbar spine BMD and uric acid remained significantly positive after excluding women older than 60 years. Conclusion: The present study showed that higher uric acid levels were linearly associated with higher lumbar spine BMD in peri- and postmenopausal Japanese women. Further research is needed to elucidate the underlying mechanism of the association between uric acid and BMD. [ABSTRACT FROM AUTHOR]

This study was conducted to identify characteristics associated with treatment for osteoporosis among women aged 50 years and older in Japan and to explore differences among patients according to treatment regimen. Data were provided by a large annual survey representative of Japanese aged 18 and older; all measures were by self-report. Women aged 50 and older who reported diagnosed osteoporosis (N = 900) were compared based on current treatment status using bivariate statistics and logistic regression. Approximately 1 in 3 women in this study reporting diagnosed osteoporosis were currently untreated. Factors associated with current treatment for osteoporosis included having ≥1 physician visit in the prior 6 months (OR = 5.4, P < 0.001), self-rated moderate or severe osteoporosis (OR = 2.8, P < 0.001), completion of menopause (OR = 1.6, P < 0.05), and family history of osteoporosis (OR = 1.5, P < 0.05), while longer duration of osteoporosis diagnosis (OR = 0.9, P < 0.05) and arthritis (OR = 0.7, P < 0.05) were associated with lower odds of treatment. These findings suggest that diagnosed patients are not being actively managed in the longer term, and efforts need to be made to ensure that patients stay engaged with their healthcare providers.

Objectives. To identify the correlates of headaches in middle-aged women and investigate the effects of Tokishakuyakusan (TJ-23), a formula of traditional Japanese herbal therapy Kampo, on headache and concomitant depression. Methods. We examined crosssectionally the baseline records of 345 women aged 40-59 years who visited our menopause clinic. Among them, 37 women with headaches were treated with either hormone therapy (HT) or TJ-23; the data of these women were retrospectively analyzed to compare the effects of the treatment. Results. The women were classified into 4 groups on the basis of their headache frequency, and no significant intergroup differences were noted in the physical or lifestyle factors, except age. Multiple logistic regression analysis revealed that the significant contributors to the women's headaches were their age (adjusted OR 0.92 (95% CI 0.88-0.97)) and their depressive symptoms (adjusted OR 1.73 (95% CI 1.39-2.16)). Compared to women treated with HT, women treated with TJ-23 reported relief from headaches (65% versus 29%) and concomitant depression (60% versus 24%) more frequently. Improvement in the scores of headaches and depression correlated significantly with TJ-23 treatment. Conclusions. Headache in middle-aged women is significantly associated with depression; TJ-23 could be effective for treating both of these symptoms. [ABSTRACT FROM AUTHOR]

Genitourinary syndrome of menopause (GSM) is a symptom complex that occurs secondary to vulvovaginal atrophy. It is generally accepted that GSM is more prevalent in postmenopausal women, and that it can affect their quality of life (QOL). However, there is little data regarding GSM in Japan. The aim of this survey was (i) to determine the prevalence of vulvovaginal symptoms of GSM among Japanese peri- and post-menopausal women and (ii) to examine whether sexual activity affected the prevalence of GSM. We conducted an online survey of 4,134 Japanese women aged 40 – 79 years in the general population. In this primary study, we focused on vulvovaginal symptoms of GSM. GSM was defined as a condition characterized by presenting at least one vaginal symptom such as vulva dryness, vulva hurting, dryness during sexual activity, and dyspareunia using the vulvovaginal symptoms questionnaire. The correlations between age, sexual activity, and GSM were analyzed. The prevalence of GSM was 11.6%. The respondents who reported GSM were more likely to be younger. The most common symptom was vulva dryness (6.0%). Only 22.0% of respondents were currently sexually active. Sexual activity was significantly correlated with GSM (P<0.01). The participants aged their 40s – 60s who had sexual activity showed an age-dependent increase in the prevalence of GSM such as vulva dryness and hurting. The respondents aged their 70s who were sexually active reported less dyspareunia than the other ages. The vulvovaginal symptoms of GSM were not found with high frequency in Japanese peri- and post-menopausal women. This primary study was conducted in limited areas of GSM. We are planning to analyze the features of GSM including urinary symptoms and QOL more comprehensively with our whole database.

Aims and objectives. To examine the characteristics of hypertension-related factors in female family caregivers in Japan who provide care in the home, in comparison with general community non-caregivers. Background. Hypertension is more frequently encountered in female caregivers than in non-caregivers. Lifestyle factors including sleep and eating habits differ in Japanese female caregivers and the general population. Therefore, hypertension-related factors in caregivers may also differ from those in the general population. Design. A cross-sectional study. Methods. The subjects were 150 female caregivers (aged 62·4, SD 12·2 years) who provided home care for persons with physical impairments and/or dementia and 154 female controls (aged 62·7, SD 2·2 years) who did not provide home care. Persons with a history of ischaemic heart disease or cerebral stroke were excluded. Subjects were examined using a self-reporting questionnaire that included a food frequency questionnaire and the tri-axial coping scale. Urine examinations and blood pressure measurements were also done. Logistic regression analysis was conducted for each group with the same variables as explanatory variables. Results. Hypertension was present in 46·7% of caregivers and 34·4% of controls ( p < 0·05). Menopause was a factor related to hypertension in both the caregivers and controls. In the caregiver group, hypertension was associated with the estimated 24-h Na excretion in urine and the carbohydrate-energy ratio for nutriti. BMI was associated with hypertension in the control group, but not in the caregiver group. Conclusions. Hypertension was associated with nutritional factors, such as greater Na excretion in urine and higher carbohydrate energy ratio, in Japanese female caregivers and with obesity in non-caregivers. Relevance to clinical practice. To prevent hypertension, it is necessary to carefully monitor salt intake and nutritional balance in female caregivers in Japan. [ABSTRACT FROM AUTHOR]

Objective: The primary objective was to investigate the association between early menopause and cardiovascular disease (CVD) prevalence in Japanese women. The secondary objective was to ascertain the association with CVD risk factors., Methods: In this cross-sectional study, 7,239 naturally menopausal women from the Yamagata Cohort Study who completed an annual health visit and questionnaire between 2009 and 2015 were divided into three groups according to their age at menopause (women experiencing menopause at <45, 45-49 y, and ≥ 50 y). The diagnosis of coronary heart disease (CHD) and stroke were made by self-report, while hypertension, hyperlipidemia, and diabetes mellitus, were diagnosed by vital signs and laboratory parameters. Logistic regression analysis was used to estimate the associations between age at menopause and CVD prevalence and CVD risk factors., Results: A total of 354 (4.9%) and 156 (2.2%) women reported a history of CHD and stroke, respectively. Women experiencing menopause at <45 years had a higher prevalence of CHD than those experiencing menopause at ≥50 years (OR 1.77, 95% CI 1.07-2.90; P = 0.023). Stroke, hypertension, diabetes mellitus, and hyperlipidemia were equally prevalent among the three groups. Significant interactions were observed between age at menopause and body mass index (BMI) (P = 0.025) and parity (P = 0.025). Among those with a BMI < 18.5 or parity ≥2, women experiencing menopause at <45 years had a significantly higher prevalence of CHD than those experiencing menopause at ≥50 years., Conclusion: Early menopause and low BMI were associated with CHD in Japanese women., Competing Interests: Financial disclosures/conflicts of interest: S.N. has received funding from Chugai Pharmaceutical Co, Ltd and AstraZeneca.

doi: 10.1111/j.1741-2358.2011.00596.x Postural stability and occlusal status among Japanese elderly Background: There are still no data available on the relationship between postural stability and occlusal status among the elderly. Objectives: To examine relationships between postural stability and occlusal status through a cohort study among elderly Japanese. Method: Oral examination, occlusal status, postural stability and a questionnaire were conducted and given to 87 community-dwelling Japanese at enrolment. Results: The average occlusal pressure of the female group was statistically higher than the male group while average occlusal pressure and postural stability length were lesser in the group with more remaining teeth. Postural stability area and number of remaining teeth showed statistically significant correlations. Postural stability length was lesser in the group with strong occlusal force. Furthermore, the number of decayed teeth was fewer in the good hygiene group. Conclusions: This study identified a close relationship between occlusal status and postural stability of Japanese older individuals. Occlusal hypofunction was observed more in those with occlusal problems, and a decrease in their occlusal functions resulted in postural instability. [ABSTRACT FROM AUTHOR]

Background: Body mass index (BMI) may be an important factor affecting breast cancer outcome. Studies conducted mainly in Western countries have reported a relationship between higher BMI and a higher risk of all-cause death or breast cancer-specific death among women with breast cancer, but only a few studies have been reported in Japan so far. In the present prospective study, we investigated the associations between BMI and the risk of all-cause and breast cancer-specific death among breast cancer patients overall and by menopausal status and hormone receptor status .Methods: The study included 653 breast cancer patients admitted to a single hospital in Japan, between 1997 and 2005. BMI was assessed using a self-administered questionnaire. The patients were completely followed up until December, 2008. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated according to quartile points of BMI categories, respectively: <21.2, ⋛21.2 to <23.3 (reference), ≥23.3 to <25.8 and ?≥5.8 kg/m2. Results: During the follow-up period, 136 all-cause and 108 breast cancer-specific deaths were observed. After adjustment for clinical and confounding factors, higher BMI was associated with an increased risk of all-cause death (HR = 2.61; 95% CI: 1.01-6.78 for BMI ?25.8 vs. ≥21.2 to <23.3 kg/m2) among premenopausal patients. According to hormonal receptor status, BMI ≥25.8 kg/m2 was associated with breast cancer-specific death (HR = 4.95; 95% CI: 1.05- 23.35) and BMI <21.2 kg/m2 was associated with all-cause (HR = 2.91; 95% CI: 1.09-7.77) and breast cancer-specific death (HR = 7.23; 95% CI: 1.57-33.34) among patients with ER + or PgR + tumors. Analysis by hormonal receptor status also showed a positive association between BMI and mortality risk among patients with ER + or PgR + tumors and with BMI ≥21.2 kg/m2 (p for trend: 0.020 and 0.031 for all-cause and breast cancer-specific death, respectively).Conclusions: Our results suggest that both higher BMI and lower BMI are associated with an increased risk of mortality, especially among premenopausal patients or among patients with hormonal receptor positive tumors. Breast cancer patients should be informed of the potential importance of maintaining an appropriate body weight after they have been diagnosed. [ABSTRACT FROM AUTHOR]

We examined whether hemorheology and platelet function are affected in essential hypertensives (EHTs) of the World Health Organization stage I when complicated with metabolic syndrome (Mets). In 156 untreated EHTs, blood viscosity and platelet surface markers were determined. Blood viscosity was significantly elevated in 54 subjects with Mets compared with 102 subjects without Mets. Hematocrit and plasma viscosity increased in the group with Mets, although red blood cell rigidity index "k" did not differ between groups. As a whole group, blood viscosity correlated positively with hematocrit and plasma viscosity. Additionally, plasma viscosity correlated positively with plasma leptin, triglyceride, homeostasis model assessment index, C-reactive protein, and plasma fibrinogen, but negatively with high-density lipoprotein cholesterol. In contrast, no differences were seen in platelet surface markers between groups. In conclusion, EHTs of the early stage complicated with Mets are characterized by increased blood viscosity due to hemoconcentration and increased plasma viscosity. [ABSTRACT FROM AUTHOR]

Purpose: Traditionally, oral estrogens have been used for hormone replacement therapy. However, in Japan, additional estrogen formulations have been used, including transdermal patches and transdermal gels. The latter have a unique commonality with cosmetics because both of them are applied to the skin. Beauty care is one of the most important lifestyle factors for women, and it has been reported that the amount of attention paid to beauty care has an effect in determining whether or not women will choose to undergo HRT during menopause. Therefore, our study focused on estrogen formulations and beauty care practices. Patients and methods: Fifty women who use hormone replacement therapy were recruited from the outpatient clinic of Tohoku University Hospital. They were treated with oral conjugated estrogen (n = 11), transdermal 17β-estradiol patch (n = 11), and transdermal 17β-estradiol gel (n = 28). They completed a questionnaire to assess their lifestyle (beauty care practices and exercise habits) and their compliance. The transdermal gel users were further interviewed about their subjective impressions regarding "smell", "sticky feeling", "spreadability", and "irritation" on the skin using a five-grade scale. Results: There were no differences in the usability of medicines and patient compliance among the estrogen formulations. We observed a positive tendency between the level of beauty care and transdermal gel use (P = 0.0645, ordinary logistic regression analysis). The gel users placed top priority on a lack of "sticky feeling" but the subjective impression regarding "sticky feeling" was worst among the four factors (P < 0.01, Steel-Dwass test). Correspondence analysis showed that the subjective impressions of transdermal gel corresponding to usability in the range of "moderate" to "very good" and "sticky feeling" greatly affected the usability of the formulation. Conclusion: These results suggest that the level of attention to beauty care plays some role in the choice of estrogen formulations. [ABSTRACT FROM AUTHOR]

Objective: To examine the effects of keishibukuryogan (TJ-25)-a medicine of the Kampo tradition (the Japanese adaptation of Chinese herbal medicine)-on middle-aged women with high blood pressure.Methods: The records of 77 peri- and postmenopausal women with high-normal blood pressure or hypertension were analyzed retrospectively. The women had participated in the Systematic Health and Nutrition Education Program at the Tokyo Medical and Dental University in Tokyo, Japan, and had received education only (controls; n = 47) or education and treatment with TJ-25 (n = 30).Results: The baseline characteristics of the 2 groups were comparable. After approximately 6 months, women in the TJ-25 group showed significant reductions in their systolic blood pressure (from 148.4mm Hg to 134.8mm Hg), diastolic blood pressure (from 89.7 mm Hg to 83.7 mm Hg), pulse rate (from 79.5 beats/min to 73.5 beats/min), and resting energy expenditure (from 1552 kcal/day to 1373 kcal/day). Several menopausal symptoms including perspiration, difficulty in initiating sleep, nonrestorative sleep, and headaches/dizziness were also improved. In addition, women in the TJ-25 group had increased health-related quality of life scores in the domains of physical health and life satisfaction.Conclusion: TJ-25 alleviates menopausal symptoms and concurrently lowers the blood pressure of middle-aged women with high blood pressure.

Aortic stiffness is widely recognized as an important, independent determinant of cardiovascular risk. The cardio-ankle vascular index (CAVI) has been developed to estimate vascular wall stiffness which is theoretically less affected by varied blood pressure. The purpose of this paper was to evaluate the change of CAVI during one-year use of raloxifene (RLX). Forty-eight women who visited the menopausal clinic in Tokyo Medical and Dental University were enrolled in this study. Twenty-two patients with osteopenia/osteoporosis (mean age 61.3 ± 1.1) out of 48 had RLX 60 mg/day (RLX group). The remaining 26 women (mean age 56.3 ± 1.0) had no medication and were recognized as younger, healthy control (control group). CAVI and ankle-brachial index were measured every 6 months, compared among 0, 6 and 12 months, in respective group. CAVI showed a significant positive correlation to age by the single linear regression analysis. Control group indicated no change of age-adjusted CAVI through 12 months, but RLX group showed significant reduction of CAVI at 6 months and increased to the original level after 12 months. On the other hand, ankle-brachial index change showed significant increase in control group, but slight increase in RLX group, suggesting no increased risk of arterial stenosis. Furthermore, CAVI in the relatively younger group (50 to 59 years; n = 11) indicated stronger reduction at 6 months than older group, suggesting high sensitivity to RLX treatment in the younger group. RLX treatment reduced CAVI value at 6 months which was superior in relatively younger group. [ABSTRACT FROM AUTHOR]

Objective To determine the prevalence and to identify the correlates of insomnia in Japanese peri- and postmenopausal women. Method We retrospectively analyzed the records of 1451 peri- and postmenopausal women enrolled in the Systematic Health and Nutrition Education Program, conducted at the Menopause Clinic of the Tokyo Medical and Dental University Hospital, between 1995 and 2009. Results The prevalence of insomnia was 50.8%. The severity of insomnia correlated negatively with health-related quality of life (HR-QOL) scores on all the four domains assessed: physical health, mental health, life satisfaction and social involvement. With regard to other menopausal symptoms, insomnia correlated more strongly with depressed mood than with vasomotor symptoms, and one-third of insomniac women were seriously depressed. On categorizing the participants into four groups – not insomniac or depressed, N; insomniac but not depressed, I; not insomniac but depressed, D; insomniac and depressed, ID – the HR-QOL scores were observed to worsen in order N > I > D > ID. No significant difference was detected between groups I and ID with regard to their sleep quality measures. The number of heavy smokers was high in groups I and ID. With regard to the effect of the combination of medication and health/nutrition education, hormone therapy and nightly hypnotics significantly improved the insomnia symptoms, but hypnotics administered ‘as needed’ did not. Conclusions Insomnia in Japanese peri- and postmenopausal women correlates more strongly with depressed mood than with vasomotor symptoms. Cessation of smoking may improve the women's sleep quality, and hormone therapy and nightly hypnotics are both effective treatments. [ABSTRACT FROM AUTHOR]
