Gender Differences in Premenstrual Syndrome and Premenstrual Dysphoric Disorder Diagnosis and Treatment among Japanese Obstetricians and Gynecologists: A Cross-Sectional Study.

Premenstrual symptoms are characterized by unpleasant psychophysical symptoms that appear during the luteal phase before menstruation and interfere with a woman's quality of life. Premenstrual syndrome (PMS) is a pathological condition with premenstrual symptoms, of which premenstrual dysphoric disorder (PMDD) is a particularly severe psychological symptom. This study aimed to examine the gender differences in the diagnosis and treatment of PMS and PMDD among obstetricians and gynecologists (OB/GYNs) in Japan. Data were obtained from the survey conducted by the Japanese Society of Obstetrics and Gynecology. We used data from 1,257 of the 1,265 OB/GYNs who are engaged in PMS/PMDD practice and reported their gender. Multivariate regression analysis adjusted for propensity scores was performed. Female OB/GYNs were more frequently engaged in treating patients with PMS/PMDD than males [odds ratio (OR) 1.74; 95% confidence interval (CI) 1.36-2.21]. With regard to the diagnostic methods, more female OB/GYNs selected the two-cycle symptom diary than males (OR 2.88; 95% CI 1.80-4.60). Regarding treatment, fewer female OB/GYNs selected selective serotonin reuptake inhibitors as their first-line drug (OR 0.39; 95% CI 0.17-0.89). Gender differences were found in the selection of PMS/PMDD diagnosis and treatment methods among Japanese OB/GYNs.

Current status and problems in the diagnosis and treatment of premenstrual syndrome and premenstrual dysphoric disorder from the perspective of obstetricians and gynecologists in Japan.

AIM: To investigate the current status and problems in the diagnosis and treatment of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) from the perspective of obstetricians and gynecologists (OB/GYNs) in Japan, the Japanese Society of Obstetrics and Gynecology (JSOG) conducted a national-wide survey. METHODS: An email survey was sent to all JSOG members (16 732) and a web-based survey was conducted using a Google form between September and November 2021. The current status and problems in PMS/PMDD diagnosis and treatment were surveyed in this cross-sectional study. RESULTS: In total, 1312 respondents (7.8% of all JSOG members) completed the questionnaire. In terms of diagnoses and treatment, OB/GYN was preferred over psychiatrist for PMS (91.4% vs. 45%); however, no differences were noted for PMDD (76.1% vs. 73.7%). A total of 1267 (96.6%) respondents engaged in routine PMS/PMDD treatment. Regarding the general diagnosis procedure, 84.4% respondents answered "only a vague medical interview," 8.4% kept a two-cycle symptom diary, and 10.3% used a screening questionnaire. The most commonly used medication was oral contraceptive pills (OCPs) (98.1%), followed by the Kampo, traditional Japanese herbal medicines, Kamishoyosan (73.6%). Concerning first-line drugs for treatment, OCPs were the most common (76.8%), followed by Kampo medicine (19.5%); selective serotonin reuptake inhibitors (SSRIs) were less frequently used (2.6%). Regarding first-line drugs among OCPs, 65.1% respondents reported drospirenone-ethinylestradriol use. CONCLUSIONS: This study indicates that only a few OB/GYNs practicing PMS/PMDD in Japan use a prospective diary, which is an essential diagnostic criterion for PMS/PMDD. Regarding treatment, SSRIs were used less frequently.

Body weight and body fat are negatively associated with severe dyspareunia in postmenopausal 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.

Pleomorphic Rhabdomyosarcoma of the Uterine Corpus in an Adult Who Underwent Multi-gene Panel Testing.

Background/Aim: Rhabdomyosarcoma (RMS) is the most common malignant soft tissue tumor in children. Adult primary RMS of gynecological origin is a rare condition and uterine RMS is an aggressive malignancy with a poor prognosis. The genetic variants associated with uterine RMS in adults have yet to be fully elucidated, and there is no established therapeutic strategy for rare tumors. Case Report: A 69-year-old Japanese woman was referred to our hospital with abdominal bloating. Imaging examination revealed a tumor with diameter of 85 mm located in the uterus and multiple regional lymph node metastases. Biopsy of the uterine corpus indicated possible uterine carcinosarcoma or RMS. Following debulking surgery, the patient was diagnosed with stage IVB pleomorphic RMS. The patient was treated with two courses of doxorubicin every three weeks and one course of combination chemotherapy with vincristine, actinomycin, and cyclophosphamide. Because of rapid progression of the disease, we decided to perform multi-gene panel testing to determine the most effective therapeutic strategy. However, no therapeutic plan based on genetic information was identified. The patient with chemotherapy-refractory RMS died 11 weeks after surgery. Conclusion: Our patient had advanced uterine RMS with an unresectable tumor that was resistant to chemotherapy, resulting in poor outcomes. Despite conducting multi-gene panel testing, no tailored therapeutic approach based on genetic information was found. This case highlights the challenges in managing uterine RMS in adults and underscores the urgent need for further research to identify effective treatment modalities.

Primary ovarian neuroendocrine carcinoma expressing substantially intense 18F-FDG uptake: A case report.

Ovarian neuroendocrine carcinoma is a rare and aggressive tumor with a poor prognosis. Ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) are often used for diagnosis. However, no specific features exist, and preoperative diagnosis is often difficult. We present a case in which ovarian neuroendocrine carcinoma was diagnosed postoperatively, with the intention to discuss its imaging features on 18F fluoro-deoxy-glucose positron emission tomography/computed tomography (18F-FDG PET/CT). A 70-year-old woman presented to a local hospital with abdominal pain. CT showed a uterine mass and multiple swollen lymph nodes. The mass expanded from the uterus into the left ovarian vessels on dynamic MRI. The SUVmax of the mass and lymph nodes on 18F-FDG PET/CT were notably elevated to 53.2 and 33.0 respectively. Considering the tumor location and high SUVmax, a malignant uterine tumor was suspected. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omental biopsy, and resection of the left ovarian vessels were performed. Histological examination confirmed that the tumor was a neuroendocrine carcinoma derived from the left ovary. To the best of our knowledge, there are only few reports on the 18F-FDG uptake in ovarian neuroendocrine carcinomas. Conversely, in other organs, the carcinomas frequently exhibit markedly elevated SUVmax on 18F-FDG PET/CT. It is possible that ovarian neuroendocrine carcinomas share similar traits, and elevated SUVmax could indicate the potential presence of this histological type.

Practical diagnosis and treatment of premenstrual syndrome and premenstrual dysphoric disorder by psychiatrists and obstetricians/gynecologists in Japan.

Aim: To investigate and compare the diagnoses and treatment of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) from the perspectives of psychiatrists and obstetricians/gynecologists (OB/GYNs) in Japan. Methods: Between December 2021 and February 2022, a web-based survey was conducted among the members of the Japanese Association of Neuro-Psychiatric Clinics. Data from 262 psychiatrists who responded to the aforementioned survey were compared with data from 409 OB/GYNs from a survey conducted in 2021 among members of the Japanese Society of Obstetrics and Gynecology. Results: Overall, 79.8% of psychiatrists and 97.3% of OB/GYNs were involved in practicing PMS/PMDD diagnosis and treatment. Most psychiatrists believed that PMS should be treated by OB/GYNs (74.4%) and PMDD by psychiatrists (75.6%). Only vague medical interviews were conducted by 86.6% of psychiatrists, and only 9.7% maintained a two-cycle symptom diary. Psychiatrists mostly prescribed selective serotonin/serotonin and noradrenaline reuptake inhibitor (SSRI/SNRI) continuous dosing (91.1%), followed by Kampo medicines, especially Kamishoyosan (73.3%); only 2.8% chose oral contraceptive pills, unlike OB/GYNs, while SSRI continuous (32.8%) and luteal phase dosing (20.6%) and Kampo medicine (42.1%) were the most common first-line treatments. Lifestyle guidance was prescribed by 63.6% of psychiatrists, followed by cognitive behavioral therapy (13.8%) and the symptom diary observation method (11.1%), which were similar to OB/GYNs' choices. Conclusions: Many Japanese psychiatrists and OB/GYNs do not base PMS/PMDD diagnoses on prospective monitoring methods using specific diagnostic criteria and therefore do not provide evidence-based treatment. Moreover, a tendency of being biased toward treatments in which the department specialized was observed.

Investigation of exacerbating factors for postpartum hair loss: a questionnaire-based cross-sectional study.

Background: Although postpartum hair loss is believed to be common, there is little reliable information. Objective: We sought to examine the factors that were associated with postpartum hair loss and to elucidate factors correlated with its pathogenesis. Methods: We carried out a questionnaire-based cross-sectional study. The study participants were women who delivered at 2 facilities and filled the questionnaire 10-18 months after delivery. The survey questionnaire included baseline characteristics, pregnancy details, delivery, childcare, and extent of postpartum hair loss. We divided participants into 2 groups according to the absence or presence of postpartum hair loss and performed logistic regression analyses. Results: A total of 331 (21.0%) responses were analyzed; among these 304 (91.8%) women had postpartum hair loss. The average time for the start, peak, and end of hair loss was 2.9, 5.1, and 8.1 months, respectively. Women with hair loss had an earlier time of delivery, a lower birth weight, a higher preterm labor rate, and longer-term breastfeeding. Logistical regression analyses revealed that longer-term breastfeeding and preterm labor were independent predictors of postpartum hair loss. The adjusted odds ratio for postpartum hair loss in women who ended breastfeeding 6-12 months postpartum versus those who ended it after 12 months or more was 5.96 (95% confidence interval [CI] [1.68, 21.09]) and 6.37 (95% CI [1.95, 20.76]) compared with those who stopped breastfeeding within 6 months postpartum. Limitations: Finer details such as pregnancy complications and delivery information may not be accurate since all results are based on questionnaire responses. There may be a sampling bias because women who suffer from postpartum hair loss may tend to participate more frequently. Conclusion: Over 90% of women experienced postpartum hair loss. Our data show that long-term breastfeeding and preterm labor correlate with postpartum hair loss.

Sleep apnea in postmenopausal women is associated with joint pain severity and fatigability: a cross-sectional study.

OBJECTIVE: This study aimed to investigate the relationships between sleep apnea parameters and various symptoms in postmenopausal women who had treatment-resistant sleep disorders. METHODS: The respiratory disturbance index (RDI), the number of times apnea-hypopnea occurred in an hour, and transcutaneous oxygen saturation (SpO2) were monitored during one night of sleep using a portable monitoring device in 51 postmenopausal women who did not have an improved subjective sleep quality with the use of hypnotics. Physical and psychological health statuses and subjective sleep disturbance were evaluated using validated questionnaires, including the Epworth Sleepiness Scale, the Cornell Medical Index, and the Questionnaire for Assessment of Climacteric Syndrome in Japanese Women. The associations between RDI, nadir SpO2 and various symptoms, as well as cardiovascular parameters, such as blood pressure, serum lipid profile, and glucose tolerance, were analyzed separately. RESULTS: Among the 51 study participants, seven (13.7%) were diagnosed with obstructive sleep apnea. After adjustment for age, body mass index, and the background factors related to RDI and nadir SpO2, the association remained significant between a higher RDI and joint pain (Questionnaire for Assessment of Climacteric Syndrome in Japanese Women) (standardized partial regression coefficient [ß] = 0.423, P  = 0.016), and between lower nadir SpO2 and fatigability (Cornell Medical Index) (ß = -0.472, P  = 0.007). CONCLUSIONS: Detailed examination of sleep-disordered breathing is warranted in women with severe joint pain and fatigability.

The Inverse Correlation of Isoflavone Dietary Intake and Headache in Peri- and Post-Menopausal Women.

This study investigated the relationship between headache and dietary consumption of a variety of nutrients in middle-aged women. This cross-sectional analysis used first-visit records of 405 women aged 40-59 years. The frequency of headaches was assessed using the Menopausal Health-Related Quality of Life Questionnaire. Of the 43 major nutrient intakes surveyed using the brief-type self-administered diet history questionnaire, those that were not shared between women with and without frequent headaches were selected. Multiple logistic regression analysis was used to identify nutrients independently associated with frequent headaches. After adjusting for background factors related to frequent headache (vasomotor, insomnia, anxiety, and depression symptoms), the estimated dietary intake of isoflavones (daidzein + genistein) (mg/1000 kcal/day) was negatively associated with frequent headaches (adjusted odds, 0.974; 95% confidence interval, 0.950-0.999). Moreover, the estimated isoflavone intake was not significantly associated with headache frequency in the premenopausal group, whereas it significantly correlated with that in the peri- and post-menopausal groups. Headache in peri- and post-menopausal women was inversely correlated with the dietary intake of isoflavones. Diets rich in isoflavones may improve headaches in middle-aged women.

Independent association of palpitation with vasomotor symptoms and anxiety in middle-aged women.

OBJECTIVE: Palpitation, or the sensation of rapid or irregular heartbeats, is common in menopausal women; however, the precise underlying mechanisms are unknown. We aimed to investigate factors associated with palpitation in middle-aged women. METHODS: Medical records of 394 women aged 40 to 59 years (108 premenopausal, 85 perimenopausal, and 201 postmenopausal) were analyzed cross-sectionally. Palpitation severity was estimated based on responses to the Menopausal Symptom Scale. Effects of background characteristics, including age, menopausal status, body composition, cardiovascular parameters, basal metabolism, physical fitness, lifestyle factors, vasomotor, and psychological symptoms on palpitation were assessed using multivariate logistic regression analysis. The association between autonomic nervous system activity and palpitation was also analyzed in 198 participants. RESULTS: Prevalence of palpitation by severity was as follows: none, 26.4%; mild, 32.7%; moderate, 29.4%; severe, 11.4%. In univariate analyses, the more severely the women were affected by palpitation, 1) the higher their systolic blood pressure, 2) the less exercise they performed, 3) the lower they scored in the sit-and-reach test, 4) the higher their vasomotor symptoms score in the Menopausal Health Related-Quality of Life questionnaire, and 5) the higher their Hospital Anxiety and Depression Scale. Multiple logistic regression analysis revealed that moderate to severe palpitation was independently associated with the vasomotor symptom score (adjusted odds ratio [95% confidence interval]: 1.18 [1.07-1.31]) and Hospital Anxiety and Depression Scale anxiety subscale score (1.19 [1.12-1.27]). CONCLUSIONS: Rapid or irregular heartbeats are highly prevalent in middle-aged women. It is not associated with age, menopausal status, heart rate, arrhythmia, autonomic nervous system activity, caffeine, or alcohol consumption, but with vasomotor symptoms and anxiety.

Depressive symptoms at postpartum are associated with those at the second trimester of pregnancy and the antioxidant activity immediately after delivery.

Objective: This study aimed to investigate whether depressive symptoms at postpartum are associated with oxidative stress and antioxidant activity, as well as the symptoms during pregnancy.Methods: This longitudinal study enrolled 84 women in their second trimester of pregnancy. Their depressive symptoms were assessed using Edinburgh postnatal depression scale (EPDS), and their oxidative stress and antioxidant activity were assessed using reactive oxygen metabolites/8-hydroxy-2'-deoxyguanosine and biological antioxidant potential (BAP) at around 26 and 36 weeks (time points 1 and 2) of gestation, and 3-6 days and 1 month (time points 3 and 4) postpartum. We evaluated the associations between EPDS at time point 4 and various parameters at the other time points.Results: Multiple regression analysis revealed that EPDS at time point 1 (adjusted odds ratio: 1.06 per 0.1 point increase; 95% confidence interval [CI]: 1.03-1.11) and BAP at time point 3 (adjusted odds ratio: 0.93 per 10 µmol/L increase; 95% CI: 0.87-0.97) were independent predictors of EPDS at time point 4.Conclusion: Depressive symptoms at the second trimester of pregnancy and the antioxidant activity immediately after delivery could predict postpartum depression. TRIAL REGISTRATION: UMIN-CTR UMIN000022367.

Depressive Symptoms in Middle-Aged and Elderly Women Are Associated with a Low Intake of Vitamin B6: A Cross-Sectional Study.

This study investigated the nutritional factors that are associated with anxiety and depressive symptoms in Japanese middle-aged and elderly women. We conducted a cross-sectional study with 289 study participants aged ≥40 years (mean age = 52.0 ± 6.9 years). Their dietary habits, menopausal status and symptoms, and varied background factors, such as body composition, lifestyle factors, and cardiovascular parameters, were assessed. Their anxiety and depressive symptoms were evaluated using the Hospital Anxiety and Depression Scale (HADS), where scores of 0-7 points, 8-10 points, and 11-21 points on either the anxiety or depression subscales were categorized as mild, moderate, and severe, respectively. The dietary consumption of nutrients was assessed using a brief self-administered diet history questionnaire. The relationships between the moderate-to-severe anxiety/depressive symptoms and the dietary intake of 43 major nutrients were investigated using multivariate logistic regression analyses. After adjusting for age, menopausal status, and the background factors that were significantly related to depressive symptoms, moderate and severe depression was significantly inversely associated with only vitamin B6 (adjusted odds ratio per 10 µg/MJ in vitamin B6 intake = 0.89, 95% confidence interval = 0.80-0.99). A higher intake of vitamin B6 could help relieve depressive symptoms for this population.

Severity of subjective forgetfulness is associated with high dietary intake of copper in Japanese senior women: A cross-sectional study.

This study investigated the relationship between subjective forgetfulness and the dietary intake of various nutrients in middle-aged and senior women. A cross-sectional study of the first-visit records of 245 Japanese women aged 40 or over was performed. The severity of subjective forgetfulness was classified according to the Menopausal Health-Related Quality of Life Questionnaire: none and mild ("unforgetful") or moderate and severe ("forgetful"). Dietary consumption of nutrients was estimated using the brief-type self-administered diet history questionnaire. The associations between the severity of subjective forgetfulness and intake of 43 major nutrients were evaluated using multivariate logistic regression analysis separately performed for two age groups: middle-aged (40-54 years, N = 166) and senior (55 years or over, N = 79). No nutrients were found to be significantly associated with subjective forgetfulness in the middle-aged group. In senior women, a significant positive relationship between the intake of copper and forgetfulness was found (adjusted odds ratio per 10 mg/kJ increase in copper intake: 1.25; 95% confidence interval: 1.08-1.50). Thus, high copper intake is positively associated with the severity of forgetfulness in Japanese senior women. Reducing copper consumption could help improve this symptom in this population.

Muscle and joint pains in middle-aged women are associated with insomnia and low grip strength: a cross-sectional study.

Background: Although muscle and joint pains are among the most common symptoms in menopausal transition, their underlying mechanisms are not precisely known. This study aimed to investigate the factors associated with myalgia and arthralgia in middle-aged women.Methods: We analyzed in a cross-sectional manner the first-visit records of 305 Japanese women aged 40-59 years who enrolled in a health and nutrition education program at a menopause clinic. The prevalence of muscle and joint pains was estimated according to the participants' responses to the Menopausal Health-Related Quality of Life Questionnaire. Background characteristics including age, menopause status, body composition, cardiovascular parameters and physical fitness, as well as other menopausal symptoms including vasomotor symptoms, insomnia, depression and anxiety, were assessed for associations with daily myalgia and arthralgia.Results: The percentage of women who were bothered by muscle and joint pains almost every day of the previous week was 56.1%. Characteristics associated with these symptoms were: low stature; high body fat percentage; low grip strength; and high vasomotor, insomnia, depression and anxiety symptom scores. Multivariate logistic regression analysis revealed that independently associated factors (adjusted odds ratio [95% confidence interval]) for daily myalgia/arthralgia were low hand-grip strength (kgf) (0.92 [0.87-0.97]) and insomnia symptom score (1.20 [1.07-1.34]).Conclusion: Muscle and joint pains are highly prevalent in Japanese middle-aged women. Low grip strength and insomnia are independently associated with these symptoms. Treatment of insomnia in this population might improve myalgia/arthralgia, and in turn, help restore grip strength, or treatment of hand pain might conversely reduce insomnia in addition to improvement in grip strength.

Daily Coffee and Green Tea Consumption Is Inversely Associated with Body Mass Index, Body Fat Percentage, and Cardio-Ankle Vascular Index in Middle-Aged Japanese Women: A Cross-Sectional Study.

This study aimed to investigate the links between coffee (CF)/green tea (GT) consumption and body composition/cardiovascular parameters in middle-aged Japanese women. We conducted a cross-sectional study of 232 Japanese women aged 40-65 years who had been referred to the menopause clinic of Tokyo Medical and Dental University Hospital between November 2007 and August 2017. Body composition, cardiovascular parameters, and CF/GT consumption frequency were evaluated on their initial visits, using a body composition analyzer, vascular screening system, and brief-type self-administered diet history questionnaire, respectively. We investigated the associations between variables using multivariate logistic regression. After adjustment for age, menopausal status, and other factors, daily CF consumption was inversely associated with high body mass index (BMI) (adjusted odds ratio, 0.14; 95% confidence interval, 0.14-0.96) and body fat percentage (BF%) (0.33; 0.14-0.82), and daily GT consumption with high BF% (0.36; 0.14-0.96). Daily CF + GT consumption was also inversely associated with high BMI (0.15; 0.05-0.50) and BF% (0.30; 0.12-0.74). In pre- and perimenopausal women, daily CF + GT consumption was inversely associated with high cardio-ankle vascular index (CAVI) (0.05; 0.003-0.743). In conclusion, daily CF/GT consumption was inversely associated with high BMI, BF%, and CAVI in middle-aged Japanese women.

Effects of Grape Seed Proanthocyanidin Extract on Vascular Endothelial Function in Participants with Prehypertension: A Randomized, Double-Blind, Placebo-Controlled Study.

This study aimed to investigate the effects of grape seed proanthocyanidin extract (GSPE) on blood pressure and vascular endothelial function in middle-aged Japanese adults with prehypertension. We conducted a randomized, double-blind, placebo-controlled study on 6 men and 24 women aged 40-64 years old. The participants were randomized to receive tablets containing either low-dose (200 mg/day) or high-dose (400 mg/day) GSPE, or placebo, for 12 weeks. Systolic and diastolic blood pressures (SBP and DBP, respectively), brachial flow-mediated dilation (FMD), and other cardiovascular parameters were measured before and after 4, 8, and 12 weeks of treatment. The mean SBP in the high-dose group significantly decreased by 13 mmHg after 12 weeks (P = 0.028), although FMD did not change. In an ad hoc analysis of non-smoking participants (n = 21), the mean SBP, DBP, stiffness parameter ß, distensibility, incremental elastic modulus (Einc), and pulse wave velocity (PWV) also significantly improved in the high-dose group after 12 weeks. Changes in Einc and PWV from baseline to 12 weeks were significantly greater in the high-dose group than in the placebo group (Einc, P = 0.023; PWV, P = 0.03). GSPE consumption could help maintain vascular elasticity and normal blood pressure in this population.

Unsalted tomato juice intake improves blood pressure and serum low-density lipoprotein cholesterol level in local Japanese residents at risk of cardiovascular disease.

The aim of this study was to investigate the effects of unsalted tomato juice intake on cardiovascular risk markers in local Japanese residents. Four hundred and eighty-one local residents in Kuriyama, Japan, were enrolled in this study. Throughout the year of the study, they were provided with as much unsalted tomato juice as they wanted. Participants were screened for cardiovascular risk markers, such as blood pressure (BP), serum lipid profile, and glucose tolerance, before and after the study period. Of the study participants, 260 participated in a detailed study of their lifestyle factors. The average ages of the 184 male and 297 female participants were 56.3 ± 13.3 (mean ± SD) and 58.4 ± 11.7 years, respectively. BP in 94 participants with untreated prehypertension or hypertension was significantly lowered (systolic BP, 141.2 ± 12.1-137.0 ± 16.3 mmHg, p = 0.003; diastolic BP, 83.3 ± 10.1-80.9 ± 11.1 mmHg, p = 0.012, paired t test). Further, the serum low-density lipoprotein cholesterol (LDL-C) level in 125 participants with untreated dyslipidemia significantly decreased (155.0 ± 23.2-149.9 ± 25.0 mg/dl, p = 0.005, paired t test). These beneficial effects were not different between sexes and among the different age groups. No significant difference in lifestyle was found before and after the study. Unsalted tomato juice intake improved systolic and diastolic BP and serum LDL-C level in local Japanese residents at risk of cardiovascular conditions.

Bone Mineral Density in Premenopausal Women Is Associated with the Dietary Intake of α-Tocopherol: A Cross-Sectional Study.

This study aimed to investigate the relationship between the consumption of various nutrients and bone mineral density (BMD) in middle-aged women. This cross-sectional survey was conducted based on the clinical records of 157 women aged 38-76. Their lumbar spine BMD was measured with dual-energy X-ray absorptiometry and dietary habits were assessed with the brief-type self-administered diet history questionnaire. Participants were divided into premenopausal (n = 46) and postmenopausal (n = 111) groups and the correlation between the BMD Z-score (Z-score) and the intakes of 43 nutrients was investigated separately for each group. In premenopausal women, the daily intake of ash, calcium, and α-tocopherol was positively correlated with the Z-score (Pearson's correlation coefficient, R = 0.31, 0.34, 0.33, p = 0.037, 0.020, 0.027, respectively). When dividing the consumption of ash, calcium, and α-tocopherol into low, middle, and high tertiles, the Z-score significantly differed only between the α-tocopherol tertiles. After adjustment for age, body mass index, and lifestyle factors, daily intake of α-tocopherol remained significantly associated with the Z-score (regression coefficient = 0.452, p = 0.022). No nutrient was found to be significantly correlated with the Z-score in postmenopausal women. Increase in the intake of α-tocopherol could help maintain bone mass in premenopausal women.

Dizziness in peri- and postmenopausal women is associated with anxiety: a cross-sectional study.

BACKGROUND: Although dizziness is one of the most common symptoms of menopause, the underlying mechanism is not precisely known. Therefore, this study aimed to investigate the prevalence of, and the factors associated with, dizziness in peri- and postmenopausal women. METHODS: We conducted a cross-sectional study in which we analyzed the first-visit records of 471 Japanese women aged 40 to 65 years who enrolled in a health and nutrition education program at a menopause clinic. The prevalence of dizziness was estimated according to the participants' responses to the Menopausal Health-Related Quality of Life Questionnaire. The background characteristics of age, menopause status, body composition, cardiovascular parameters, basal metabolism, and physical fitness; other menopausal symptoms, including vasomotor, insomnia, depression, and anxiety symptoms; and lifestyle characteristics were assessed for their associations with dizziness. RESULTS: The percentage of women who suffered from dizziness once a week or more frequently was 35.7%. Compared to the women without dizziness, those with the symptom were younger; had a higher body weight, body mass index, body fat percentage, muscle mass, and waist-to-hip ratio; had higher systolic pressure; were slower in reaction time; had higher physical and psychological symptom scores of menopause; exercised less regularly; and consumed less alcohol. A multivariate logistic regression analysis revealed that the anxiety symptom, which was evaluated by the Hospital Anxiety and Depression Scale, was the sole factor that was independently associated with dizziness (adjusted odds ratio 1.14; 95% confidence interval 1.08-1.20). CONCLUSIONS: Dizziness is highly prevalent in Japanese peri- and postmenopausal women and it is associated with anxiety. The treatment of anxiety in this population might improve the symptom.
