The relationship of nutrients intake and bone mineral density (BMD) was investigated in 285 Korean postmenopausal women (age 40-70 y) consisted of 65 normal women and 159 osteopenia patients who don't have other diagnosed disease. BMD was measured at the spine (vertebrae L2-4) and femur (neck, Ward's triangle and trochanter). Height, weight, body mass index(BMI), lean body mass(LBM), body fat(Bfat) and dietary intakes of animal calcium(animal Ca), protein and phosphorus per 1,000kcaI intake were correlated with BMD of the spine and the femur positively(p<0.05). Women with an animal calcium intake < 315mg/d (mean % animal Ca/total Ca intake > 50%) exhibited significantly lower BMD of the spine and Ward's triangle than that of women with an intake > 315mg/d, p<0.OS. When subjects were grouped by diagnosis into 3 groups (normal, osteopenia and osteoporosis group), animal Ca intake of osteoporosis group (mean animal Ca intake 261mg) was significantly lower than those of the other two groups (mean animal Ca intake 306mg and 297mg, respectively), p < 0.05. These results suggest that balanced nutrients intake and increased animal Ca in the diet is likely to be beneficial in reducing bone loss in postmenopausal women.

Various microorganisms reside in the human vagina; the vaginal microbiome is closely linked to both vaginal and general health, and for this reason, microbiome studies of the vagina are an area of research. In this study, we analyzed the vaginal microbiome of women before and after menopause to further increase our understanding of the vaginal microbiome and its contribution to general health. We did a 16s rRNA gene-based metagenomic analysis on the vaginal fluids of 11 premenopausal and 19 postmenopausal women in Korea. We confirmed that the taxonomic composition was significantly different between the two groups. In postmenopausal women, species richness was significantly decreased, but species diversity was significantly increased. In particular, among the taxonomic components corresponding to all taxon ranks of the vaginal microbiome, a reduction in Lactobacillus taxa after menopause contributed the most to the difference between the two groups. In addition, we confirmed through metabolic analysis that the lactic-acid concentration was also decreased in the vaginal fluid of women after menopause. Our findings on the correlation between menopause and the microbiome could help diagnose menopause and enhance the prevention and treatment diseases related to menopause.

Objective: The purpose of this study was to evaluate the effects of soybean intake on bone mineral density and bone turnover markers in postmenopausal rural Korean women. Method: This study was carried out during nine months from Oct. 25 2004 to Aug. 31 2005. The subjects of this study were female patients over 50 living in rural areas diagnosed with osteoporosis. There were 18 women in the experimental group and 20 in the control group. In this study, the experimental group received 100 mg of isoflavone (soybean) and calcium 1,500 mg for nine months while the control group received 1,500mg of calcium only. Results: After the soybean intake, the change of bone mineral density between the experimental group and control group was statistically significant. However, the bone turnover markers of osteocalcin and deoxypyridinoline between the experimental group and control group were not significantly different statistically. In the Pearson Correlation between bone mineral density and bone turnover markers, the osteocalcin and deoxypyridinoline of the experimental group had a positive correlation, and osteocalcin and DPD/osteocalcin ratio had anegative correlation. In the control group, osteocalcin and DPD/osteocalcin ratio had a negative correlation. Conclusions: This result showed that soybean intake changed bone mineral density in postmenopausal woman.

Purpose: The study was aimed at investigating changes in periodontal parameters and superoxide dismutase activity triggered by root surface debridement with and without micronutrient supplementation in postmenopausal women. Methods: Forty-three postmenopausal chronic periodontitis patients were divided into two groups: group 1 (n=22) were provided periodontal treatment in the form of scaling and root planing (SRP) and group 2 (n=21) patients received SRP along with systemic administration of micronutrient antioxidants. Patients in both groups were subjected to root surface debridement. Group 2 patients also received adjunctive micronutrient antioxidant supplementation. Serum and salivary superoxide dismutase (SOD) activity along with periodontal parameters were recorded at baseline and 3 months after therapy. Results: Salivary and serum SOD values significantly (P<0.05) improved with periodontal treatment. Improvement in systemic enzymatic antioxidant status along with reduction in gingival inflammation and bleeding on probing (%) sites was significantly greater in group 2 as compared to group 1. Conclusions: Adjunctive micronutrient supplements reduce periodontal inflammation and improve the status of systemic enzymatic antioxidants in postmenopausal women.

Objectives Although forgetfulness is a common complaint among menopausal depressed women, there is still a debate about the relationship between memory impairment and menopause. The aim of this study is to examine whether menopause is related to cognitive decline among women with depressive disorders. We hypothesized that postmenopausal depressed women show generally poorer performance than premenopausal depressed women on various cognitive function tests. Methods With a retrospective chart review, we identified a total of 87 female patients (45 premenopausal patients and 42 postmenopausal patients) who were hospitalized with depressive disorders from 2000 to 2016. Demographic and clinical variables and cognitive test results were compared between two groups. Results Education year is longer in premenopausal group than postmenopausal group whereas clinical characteristics (illness duration, recurrence, and symptom severity) and mean Intelligence Quotient (IQ) were similar between two groups. The postmenopausal group took longer time for Bender-Gestalt Test (BGT) recall, Trail Making Test (TMT)-A, and TMT-B than the premenopausal group. After controlling for age and education, significant difference was remained for BGT recall (p = 0.029). Conclusions Postmenopausal state may be related with decline of visuospatial memory function, in particular, among depressed female patients. Other areas of cognitive function including complex attention, verbal memory, auditory memory, and working memory might be interpreted while considering age and education level.

Background: There has been much research work in the past to ascertain the association between type 2 diabetes mellitus and breast cancer, but definitive evidence has been scanty. The present study was carried out to determine the association of type 2 diabetes mellitus with breast cancer in the female population of Northern Pakistan. Materials and Methods: This case-control study was carried out in the Oncology Department of NORI Hospital. A total of 400 patients were included. Data were entered into PSPP 0.8.1. Two-tailed significance tests were used and a p-value of 0.05 was considered significant. Results: There were a higher percentage of postmenopausal women in the diabetic breast cancer patients' group as compared to the non-diabetic subset. The odds ratio for the association between diabetes and risk of developing breast cancer was elevated with statistical significance (OR = 2.96; 95 % CI =1.3-6.3; p-value=0.004). The results of our study showed that diabetes is associated with a risk of developing breast cancer, especially in postmenopausal women (OR = 4.928; 95 % CI = 2.1-11.3; p-value=0.001). The association was particularly marked in obese subjects (OR = 31.49; 95 % CI = 1.8-536; p- value=0.01), as compared to non-obese subjects (OR = 0.642; 95 % CI = 0.2-1.7). Conclusions: Diabetes is strongly associated with obesity and it tends to increase the risk of breast Cancer, especially in postmenopausal women. A high-risk subset for breast cancer comprised postmenopausal, diabetic and overweight women.

Currently bone biochemical markers are considered to be the best indicators of present and the future state of bone turnover. A recent study has reported that chlorella increases the bone mineral density (BMD) on postmenopausal women, but presently there are no studies on bone biochemical markers treated with chlorella dietary supplementation. The purpose of the present study was to assess the bone biochemical markers for the short term and long term treatment groups, and non-treatment group as a control. Twenty two postmenopausal woman were treated for four months and eighteen for one year with 4 gm of chlorella dietary supplementation per day, and then assessed bone biochemical markers from serum and urine samples. Bone turnover rates calculated with Osteocalcin (OC), bone specific alkaline phosphatase (BAP) as a bone formation markers and deoxypyridinoline (DP), cross-linked N-telopeptides of type I collagen (NTx) as a bone resorption markers, showed 1131$\pm$87% for control group, 61$\pm$11% for short term treated group and 190$\pm$101% for long term treated group. We conclude that chlorella dietary supplementation enhances the bone formation, and NTx as a single markers, OC/Dp as a single markers of bone turnover rate were very useful tools for determine the effectiveness of chlorella dietary supplementation (or the postmenopausal women.

The purpose of this study was to evaluate the relationship between the osteoporotic condition and periodontal condition in postmenopausal women with periodontitis. Forty three female postmenopausal patients with no systemic disease were grouped into 3 groups by their periodontal conditions; 12 mild periodontitis, 11 moderate periodontitis and 20 advanced periodontitis. From each patient, age of menopause was taken, alkaline phosphatase(ALP) and osteocalcin (OC) in blood and deoxypyridinoline (DPD) in urine were measured. Bone mineral density (BMD) of lumbar spine (L2-L4) was measured by dual energy X-ray absorptiometry. Periodontal and osteoporotic parameters were compared among the groups and correlation coefficient between them was evaluated. The blood ALP and OC levels were similar among the groups with different periodontal condition, whereas the urine DPD level and BMD were significantly lower in advanced periodontitis group than the other groups(p<0.01). Probing depth was negatively related with BMD (r=-0.5, p<0.01) and positively related with patient age and the duration of menopause (r= 0.32 and 0.35 respectively, p<0.05). Clinical attachment loss was negatively related with BMD (r=-0.66, p<0.01), and positively related with urine DPD (r= 0.37, p<0.05). These results showed that postmenopausal women with advanced periodontitis had significantly decreased bone mineral density and suggests that decreased bone mineral density in postmenopausal women could be associated with periodontal tissue breakdown.

Purpose: The present study was designed to compare the incidence of periodontitis according to menopausal status and to investigate the possible effect of hormone replacement therapy (HRT) on periodontitis in postmenopausal women using a common data model (CDM) at a single institution. Methods: This study involved retrospective cohort data of 950,751 patients from a 20-year database (2001 to 2020) of Ewha Womans University Mokdong Hospital converted to the Observational Medical Outcomes Partnership CDM. One-way analysis of variance models and the χ² test were used to analyze the statistical differences in patient characteristics among groups. A time-dependent Cox regression analysis was used to calculate hazard ratios and 95% confidence intervals, and P values less than 0.05 were considered to indicate statistical significance. Results: Of the 29,729 patients, 1,307 patients were diagnosed with periodontitis and 28,422 patients were not. Periodontitis was significantly more common among postmenopausal patients regardless of HRT status than among the non-menopausal group (P<0.05). Time-dependent Cox regression analysis showed that the postmenopausal patients had a significantly higher chance of having periodontitis than non-menopausal patients (P<0.05), but after adjustment for age, body mass index, and smoking status, the difference between the non-menopausal and post-menopausal HRT-treated groups was insignificant (P=0.140). Conclusions: Postmenopausal women had a significantly greater risk of periodontitis than non-menopausal women. Additionally, the use of HRT in postmenopausal women could reduce the incidence of periodontitis.

PURPOSE: The purpose of this study was to examine the association of waist to height ratio (WHtR) and resting heart rate (RHR) with cardio-metabolic risk factors among Korean postmenopausal women. METHODS: A cross-sectional analysis was performed using the 2015 Korea National Health and Nutrition Examination Survey. The analysis included a total of 1,540 postmenopausal women. RESULTS: Individuals with higher WHtR (>0.56) showed significantly higher glucose, triglyceride, insulin, Homeostatic Model Assessment for Insulin resistance (HOMA-IR), total cholesterol, systolic and diastolic blood pressure compared with ones with lower WHtR (≤0.51). Similar findings were found in those with higher RHR (≥90 bpm) compared with ones with lower RHR (<60 bpm) for glucose and HOMA-IR. When determining the combined effects of WHtR and RHR on the prevalence of metabolic syndrome, individual with WHtR above 0.5 and RHR above 80 bpm showed 10.39 times higher prevalence of metabolic syndrome compared with those with WHtR below 0.5 and RHR below 70 bpm. We further performed multiple linear regression analysis to understand how WHtR and RHR contribute to fasting glucose, and found that both WHtR and RHR contribute to fasting glucose levels independent of age, education level, marital status and income level. CONCLUSIONS: The current study showed that the WHtR and RHR are associated with cardio-metabolic risk factor and prevalence of metabolic syndrome in Korean postmenopausal women.
