Postmenopausal women are known to have a higher prevalence of metabolic syndrome compared with premenopausal women. However, there are few studies that have investigated the effects of reproductive factors on metabolic syndrome in postmenopausal women. The objective of this study was to evaluate the association between reproductive factors and metabolic syndrome in postmenopausal women. A total of 892 postmenopausal women who participated in the 2005 Korean National Health and Nutrition Examination Survey were included. We determined an association between reproductive factors and metabolic syndrome. Using a multivariate logistic regression analysis, it was found that age at first birth was negatively associated with metabolic syndrome. Having the first baby at a later age was associated with a decreased risk of having metabolic syndrome (odds ratio, 0.95; 95% CI, 0.90-0.99). However, other reproductive factors including age at menarche, age at menopause, parity, lifetime estrogen exposure, years since menopause, number of pregnancies, history of lactation, and oral contraceptives or hormone therapy use were not associated with metabolic syndrome. Among various reproductive factors, age at first birth was negatively associated with metabolic syndrome in Korean postmenopausal women.

The efficacy and safety of palbociclib, a cyclin-dependent kinase 4/6 inhibitor, combined with fulvestrant and goserelin was assessed in premenopausal women with advanced breast cancer (ABC) who had progressed on prior endocrine therapy (ET). One hundred eight premenopausal endocrine-refractory women ≥18 years with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) ABC were among 521 women randomized 2:1 (347:174) to fulvestrant (500 mg) ± goserelin with either palbociclib (125 mg/day orally, 3 weeks on, 1 week off) or placebo. This analysis assessed whether the overall tolerable safety profile and significant progression-free survival (PFS) improvement extended to premenopausal women. Potential drug-drug interactions (DDIs) and ovarian suppression with goserelin were assessed via plasma pharmacokinetics and biochemical analyses, respectively. (ClinicalTrials.gov identifier: NCT01942135) RESULTS: Median PFS for premenopausal women in the palbociclib ( n  = 72) versus placebo arm ( n  = 36) was 9.5 versus 5.6 months, respectively (hazard ratio, 0.50, 95% confidence interval: 0.29-0.87), and consistent with the significant PFS improvement in the same arms for postmenopausal women. Any-grade and grade ≤3 neutropenia, leukopenia, and infections were among the most frequent adverse events reported in the palbociclib arm with concurrent goserelin administration. Hormone concentrations were similar between treatment arms and confirmed sustained ovarian suppression. Clinically relevant DDIs were not observed. Palbociclib combined with fulvestrant and goserelin was an effective and well-tolerated treatment for premenopausal women with prior endocrine-resistant HR+/HER2- ABC. Inclusion of both premenopausal and postmenopausal women in pivotal combination ET trials facilitates access to novel drugs for young women and should be considered as a new standard for clinical trial design.

There have been few population-based studies reporting medical, lifestyle and psychological factors associated with irregular menstrual cycles. This study aimed to elucidate the prevalence and related factors of irregular menstrual cycles in Korean women. Cross-sectional data from the 5th Korean National Health and Nutrition Examination Survey were used. Eligible women were 19-40 years old, not currently taking oral contraceptives or using intrauterine devices, and not currently pregnant or breast feeding, and had no medical history of hysterectomy, thyroid diseases, cancers or renal failure. Finally, 3194 premenopausal women were recruited in this study. The prevalence and related factors of irregular cycles were obtained using a general linear model and logistic regression analyses in a complex sampling design. The prevalence of irregular cycles was 14.3%. Age and high-education level were associated with lower odds ratios (ORs) for irregular cycles (OR 0.91, 95% confidence interval (95% CI) 0.87-0.96, and OR 0.58, 95% CI 0.38-0.88, respectively). The ORs of body mass index, perceived stress and depressive mood were 1.05 (95% CI 1.01-1.10), 1.46 (95% CI 1.11-1.92) and 2.07 (95% CI 1.18-3.63), respectively. Age, perceived stress, body mass index, depressive mood and education level, rather than obstetric factors or metabolic diseases were significant factors associated with irregular menstrual cycles in Korean women. Of these factors, perceived stress is the most significant factor associated with increased irregular menstrual cycles.

This study was to examine the effects of self-foot reflexology on stress, fatigue and blood circulation in premenopausal middle-aged women. A quasi-experimental nonequivalent control group, pretest-posttest design was used. Participants were 59 premenopausal, middle-aged women in their 40s and 60s living in G city: 30 in the experiment group and 29 in the control group. Data were collected from May to August 2008. Self-foot reflexology was performed three times a week for 6 weeks for 40 min at each session. The results showed that self-foot reflexology was effective in reducing perceived stress and fatigue and helped blood circulation in premenopausal middle-aged women. Self-foot reflexology may be an effective nursing intervention in reducing perceived stress and fatigue and in improving blood circulation.

Orthodontic treatment is one of the commonly used dental treatments. Orthodontic forces act on the bone by modulating the biomolecules, chiefly the osteoprotegerin (OPG), osteopontin (OPN), receptor activator of nuclear factor kappa-B (RANK), and RANK ligand (RANKL) (OPG ligand). Hormonal changes are known to cause marked alteration in the levels of these biomolecules. Hence, we planned this study to evaluate the response of bone biomarkers in the gingival crevicular fluid (GCF) in postmenopausal women undergoing fixed orthodontic therapy. This study included assessment of 50 subjects who underwent orthodontic treatment from June 2012 to July 2016. All the patients were divided into two study groups with 25 patients in each group: premenopausal group and postmenopausal group. Similar orthodontic wires were used for controlling the forces applied in subjects of both the study groups and their GCF levels of RANKL, and OPN was assessed at baseline and 24 hours after the activation of orthodontic forces. All the results were compiled, assessed, and analyzed by Statistical Package for the Social Sciences software version 16.0. Chi-square test, Student's t-test, and Mann-Whitney U test were used for the assessment of the level of significance. The mean values of RANKL and OPN in the premenopausal and postmenopausal groups were found to be 241.52 and 317.15 pg/μL respectively. The mean values of RANKL at baseline in the premenopausal and postmenopausal groups were found to be 7.15 and 3.84 pg/μL respectively. Nonsignificant results were obtained while comparing mean OPN and RANKL level alteration in between the two study groups. The mean alterations in the GCF levels of bone biomarkers are similar for both premenopausal and postmeno-pausal women. For women with either premenopausal or postmenopausal status, orthodontic treatment appears to be equally safer.

Weight gain is a common problem in breast cancer patients and is reported to be associated with poorer survival. However, most data are limited to Western women. We evaluated weight changes after adjuvant treatment in Korean women with early breast cancer. The authors reviewed the records of 260 patients with stage I-III breast cancer treated between June 2003 and February 2006. Body weight, body mass index (BMI) and menopausal status at baseline and after 3, 6, 12 and 24 months of adjuvant treatment were reviewed. Mean patient age was 47.0 years and 61.1% of women were premenopausal. Among them, 195 patients (75.8%) received chemotherapy and 186 (71.5%) received hormonal therapy. Mean baseline weight was 57.5 +/- 9.8 kg and mean BMI was 23.5 +/- 1.6 kg/m(2) (22.8 +/- 3.0 vs. 24.7 +/- 3.2 kg/m(2) for pre- vs. post-menopausal women, P = 0.286). Mean weight changes were; 0.30 kg at 3 months (P = 0.019); 0.16 kg at 6 months (P = 0.367); -0.34 kg at 1 year (P = 0.082); -0.40 kg at 2 years (P = 0.097). Twenty-three patients (10.4%) gained more than 5% of baseline body weight at 1 year, but no clinical variable was found to be associated with these weight gains. This study shows that Korean women with early breast cancer do not gain weight after adjuvant treatment. Further studies are needed to determine differences between Asian and Western women in terms of weight changes and prognosis in early breast cancer.

Menopause is associated with increased risk of cardiovascular disease and the causal factors have been proposed to be the loss of estrogen and the subsequent alterations of the hormonal milieu. However, which factors contribute to the deterioration of cardiometabolic health in postmenopausal women is debated as the menopausal transition is also associated with increased age and fat mass. Furthermore, indications of reduced cardiometabolic adaptations to exercise in postmenopausal women add to the adverse health profile. We sought to evaluate risk factors for type 2 diabetes and cardiovascular disease in late premenopausal and early postmenopausal women, matched by age and body composition, and investigate the effect of high-intensity training. A 3-month high-intensity aerobic training intervention, involving healthy, nonobese, late premenopausal (n = 40) and early postmenopausal (n = 39) women was conducted and anthropometrics, body composition, blood pressure, lipid profile, glucose tolerance, and maximal oxygen consumption were determined at baseline and after the intervention. At baseline, the groups matched in anthropometrics and body composition, and only differed by 4.2 years in age (mean [95% confidence limits] 49.2 [48.5-49.9] vs 53.4 [52.4-54.4] years). Time since last menstrual period for the postmenopausal women was (mean [95% confidence limits] 3.1 [2.6-3.7] years). Hormonal levels (estrogen, follicle stimulation hormone, luteinizing hormone) confirmed menopausal status. At baseline the postmenopausal women had higher total cholesterol (P < .001), low-density lipoprotein-cholesterol (P < .05), and high-density lipoprotein-cholesterol (P < .001) than the premenopausal women. The training intervention reduced body weight (P < .01), waist circumference (P < .01), and improved body composition by increasing lean body mass (P < .001) and decreasing fat mass (P < .001) similarly in both groups. Moreover, training resulted in lower diastolic blood pressure

This study compared BMD relative to body weight following a ∼6-month weight loss program and a 1-year weight maintenance phase in premenopausal women and determined whether African American (AA) and European-American (EA) women's BMD respond similarly during weight loss. Premenopausal women (n = 115, 34 ± 5 years) were evaluated in an overweight state (BMI between 27 and 30 kg/m(2) ), following an 800 kcal/day diet/exercise program designed to reduce BMI<25 kg/m(2) , and 1-year following weight loss. BMD relative to body weight (Z-scores) increased after weight loss, but decreased during the 1-year weight maintenance phase. All 1-year follow-up BMD Z-scores were increased (except L1) compared to baseline measurements (P < 0.05). These sites included the hip neck (+0.088, P = 0.014), total hip (+0.099, P = 0.001), L2 (+0.127, P = 0.013), L3 (+0.135, P = 0.014), and L4 (+0.199, P = 0.002). AAs had significantly higher absolute BMD at all sites (P < 0.05) compared to EAs, but no time by race interactions were evident during weight loss (except in L3). These results may indicate that weight loss is safe with regard to bone health for overweight premenopausal women. Copyright © 2013 The Obesity Society.

Moderate alcohol consumption is associated with a reduced risk of coronary heart disease. Earlier studies in men have shown that moderate alcohol consumption affects lipoprotein metabolism and hemostasis. In this diet-controlled, randomized, crossover trial, we investigated the effect on lipoprotein metabolism of moderate consumption of red wine or red grape juice with evening dinner for 3 weeks in premenopausal women using oral contraceptives and in postmenopausal women. After 3 weeks, blood samples were collected 1 hour before dinner up to 19 hours after starting dinner at 2-hour or 4-hour intervals. Plasma triglyceride concentrations and very low density lipoprotein (VLDL) triglyceride levels peaked 3 hours after dinner with wine in both premenopausal and postmenopausal women. After wine consumption, the overall high-density lipoprotein (HDL) cholesterol level was increased in postmenopausal women (mean increase 0.17 mmol/L, or 12%, p = 0.03), and the plasma low-density lipoprotein (LDL) cholesterol level was reduced in premenopausal women (mean reduction 0.35 mmol/L, or 12%, p = 0.01) as compared with grape juice consumption. The findings suggest that postprandial lipoprotein metabolism after moderate alcohol consumption differs between oral contraceptive-using premenopausal women and postmenopausal women. The response of postmenopausal women to alcohol resembled the response found in earlier studies in men.

The polycystic ovary syndrome (PCOS) is a complex polygenic disorder in which environmental factors play an important modifying role. We aimed to find differences in diet and life-style that might contribute to the development of PCOS among overweight or obese premenopausal women. We compared diet composition and self-reported physical activity among 22 patients with PCOS and 59 women without androgen excess recruited from a total of 113 consecutive premenopausal women reporting for management of weight excess. After correcting for a difference in age between women with PCOS and controls, there were no overall statistical significant differences between them in the total caloric intake, in the intake of macro- and micro-nutrients, caffeine, fiber and alcohol, in the proportion of women exercising regularly, or in the number of hours of exercise per week. The proportion of fat in the diets of the overweight and obese women irrespective of PCOS was well-above current recommendations, yet this excessive fat intake occurred at the expense of monounsaturated fatty acids mostly. In conclusion, diet composition and physical activity were apparently not decisive for the development of PCOS among overweight and obese premenopausal women.

We aimed at the evaluation of the relationship between adipocyte fatty acid binding protein (A-FABP) and cardiometabolic risk factors in premenopausal and postmenopausal women. Additionally, we compared A-FABP with adipokines related to metabolic syndrome (MetS) such as leptin and adiponectin. 94 premenopausal and 90 early postmenopausal middle-aged Caucasian women were subject to examinations. Postmenopausal women had higher A-FABP than premenopausal; this difference became insignificant after controlling for age. We found significantly higher correlation coefficients between A-FABP and TC/HDL-C ratio and number of MetS components in premenopausal women, compared to postmenopausal. Each 1 ng/dL increase in A-FABP concentration significantly increased the probability of occurrence of atherogenic lipid profile in premenopausal women, even after multivariate adjustment. All odds ratios became insignificant after controlling for BMI in postmenopausal women. A-FABP was more strongly associated with MetS than leptin and adiponectin in premenopausal women. Adiponectin concentration was a better biomarker for MetS after menopause. Our results suggest that the A-FABP is more strongly associated with some cardiometabolic risk factors in premenopausal than in postmenopausal women. Higher values of A-FABP after menopause are mainly explained by the fact that postmenopausal women are older. Because of the limitation of study, these results should be interpreted with caution.

Exposure to metals, specifically cadmium, lead, and mercury, is widespread and is associated with reduced bone mineral density (BMD) in older populations, but the associations among premenopausal women are unclear. Therefore, we evaluated the relationship between these metals in blood and BMD (whole body, total hip, lumbar spine, and non-dominant wrist) quantified by dual energy X-ray absorptiometry in 248 premenopausal women, aged 18-44. Participants were of normal body mass index (mean BMI 24.1), young (mean age 27.4), 60% were white, 20% non-Hispanic black, 15% Asian, and 6% other race group, and were from the Buffalo, New York region. The medianmore » (interquartile range) level of cadmium was 0.30 {mu}g/l (0.19-0.43), of lead was 0.86 {mu}g/dl (0.68-1.20), and of mercury was 1.10 {mu}g/l (0.58-2.00). BMD was treated both as a continuous variable in linear regression and dichotomized at the 10th percentile for logistic regression analyses. Mercury was associated with reduced odds of decreased lumbar spine BMD (0.66, 95% confidence interval: 0.44, 0.99), but overall, metals at environmentally relevant levels of exposure were not associated with reduced BMD in this population of healthy, reproductive-aged women. Further research is needed to determine if the blood levels of cadmium, lead, and mercury in this population are sufficiently low that there is no substantive impact on bone, or if effects on bone can be expected only at older ages.« less

We examined the relationships between bone mineral density (BMD) and metabolic syndrome in 6,659 men and 7,826 women from South Korean. After adjusting for age, body mass index (BMI), tobacco and alcohol use, and regular exercise, low BMD is especially associated with metabolic syndrome in South Korean men. This study examined the relationships between BMD and metabolic syndrome (MS) in South Korean adults. A total of 14,485 adults (6,659 men and 7,826 women) in the Korea National Health and Nutrition Examination Survey conducted from 2008 to 2010 were analyzed. We used multivariable regression models to examine the relationship between low BMD and MS. We calculated homeostasis model assessment and insulin resistance (HOMA-IR). MS was defined according to AHA/NHLBI criteria for Asians. BMD was measured at the lumbar spine (LS), femur neck (FN), total hip (TH), trochanter, and intertrochanter. After adjustment for age, BMI, tobacco and alcohol use, and regular exercise, the TH and FN BMD were significantly lower in men with MS than in men without MS (p < 0.05). However, there were no differences in premenopausal and postmenopausal women. In men, BMD was positively correlated with BMI, and high density lipoprotein cholesterol, but was negatively correlated with insulin, HOMA-IR, and triglyceride at all three sites (p < 0.05). Along with an increase of BMD (0.1 g/cm²), the odds ratios (ORs) for obesity and abdominal obesity were all greater than 1 at all sites in both genders. The ORs for hypertension and MS were 0.937 (0.879-0.998) and 0.899 (0.840-0.962), respectively at FN, and the OR for diabetes mellitus was 1.103 (1.017-1.196) at LS in men. In postmenopausal women, the OR for hypertension was 1.133 (1.029-1.246) at LS. Low BMD was especially associated with MS in South Korean men.

Postmenopausal Women Have Higher HDL and Decreased Incidence of Low HDL than Premenopausal Women with Metabolic Syndrome

It is well known that plasma lipids, waist circumference (WC) and blood pressure (BP) increase following menopause. In addition, there is a perceived notion that plasma high-density lipoprotein-cholesterol (HDL-C) concentrations also decrease in postmenopausal women. In this cross-sectional study, we evaluated plasma lipids, fasting glucose, anthropometrics and BP in 88 post and 100 pre-menopausal women diagnosed with metabolic syndrome. No differences were observed in plasma low-density lipoprotein-cholesterol cholesterol, triglycerides, fasting glucose or systolic and diastolic BP between groups. However, plasma HDL-C was higher (p < 0.01) in postmenopausal women and the percentage of women who had low HDL (<50 mg/dL) was higher (p < 0.01) among premenopausal women. In addition, negative correlations were found between WC and HDL-C (r = −0.148, p < 0.05) and BMI and HDL-C (r = −0.258, p < 0.01) for all subjects indicating that increases in weight and abdominal fat have a deleterious effect on plasma HDL-C. Interestingly, there was a positive correlation between age and plasma HDL-C (r = 0.237 p < 0.01). The results from this study suggest that although HDL is decreased by visceral fat and overall weight, low HDL is not a main characteristic of metabolic syndrome in postmenopausal women. Further, HDL appears to increase, not decrease, with age. PMID:27417608

Fibroblast growth factor 23 (FGF23) circulates as active protein and inactive fragments. Low iron status increases FGF23 gene expression, and iron deficiency is common. We hypothesized that in healthy premenopausal women, serum iron influences C-terminal and intact FGF23 concentrations, and that iron and FGF23 associate with bone mineral density (BMD). Serum iron, iron binding capacity, percent iron saturation, phosphorus, and other biochemistries were measured in stored fasting samples from healthy premenopausal white (n=1898) and black women (n= 994), age 20–55 years. Serum C-terminal and intact FGF23 were measured in a subset (1631 white and 296 black women). BMD was measured at the lumbar spine and femur neck. Serum phosphorus, calcium, alkaline phosphatase and creatinine were lower in white women than black women (p<0.001). Serum iron (p<0.0001) and intact FGF23 (p< 0.01) were higher in white women. C-terminal FGF23 did not differ between races. Phosphorus correlated with intact FGF23 (white women, r=0.120, p<0.0001; black women r=0.163, p<0.01). However, phosphorus correlated with C-terminal FGF23 only in black women (r=0.157, p<0.01). Intact FGF23 did not correlate with iron. C-terminal FGF23 correlated inversely with iron (white women r=−0.134, p<0.0001; black women r=−0.188, p<0.01), having a steeper slope at iron <50 mcg/dl than >50 mcg/dl. Longitudinal changes in iron predicted changes in C-terminal FGF23. Spine BMD correlated with iron negatively (r=−0.076, p<0.01) in white women; femur neck BMD correlated with iron negatively (r=−0.119, p<0.0001) in black women. Both relationships were eliminated in weight-adjusted models. BMD did not correlate with FGF23. Serum iron did not relate to intact FGF23, but was inversely related to C-terminal FGF23. Intact FGF23 correlated with serum phosphorus. In weight-adjusted models, BMD was not related to intact FGF23, C-terminal FGF23 or iron. The influence of iron on FGF23 gene expression is not important

Clinical guidelines recommend that women with abnormal uterine bleeding with risk factors have an endometrial biopsy to exclude hyperplasia or cancer. Given the majority of endometrial cancer occurs in postmenopausal women, it has not been widely recognized that obesity is a significant risk factor for endometrial hyperplasia and cancer in young, symptomatic, premenopausal women. We sought to evaluate the effect of body mass index on risk of endometrial hyperplasia or cancer in premenopausal women with abnormal uterine bleeding. This was a retrospective cohort study in a single large urban secondary women's health service. Participants were 916 premenopausal women referred for abnormal uterine bleeding of any cause and had an endometrial biopsy from 2008 through 2014. The primary outcome was complex endometrial hyperplasia (with or without atypia) or endometrial cancer. Almost 5% of participants had complex endometrial hyperplasia or cancer. After adjusting for clinical and demographic factors, women with a measured body mass index ≥30 kg/m 2 were 4 times more likely to develop complex hyperplasia or cancer (95% confidence interval, 1.36-11.74). Other risk factors were nulliparity (adjusted odds ratio, 3.08; 95% confidence interval, 1.43-6.64) and anemia (adjusted odds ratio, 2.23; 95% confidence interval, 1.14-4.35). Age, diabetes, and menstrual history were not significant. Obesity is an important risk factor for complex endometrial hyperplasia or cancer in premenopausal women with abnormal uterine bleeding who had an endometrial biopsy in a secondary gynecology service. As over half of women with the outcome in this study were age <45 years, deciding to biopsy primarily based on age, as currently recommended in national guidelines, potentially misses many cases or delays diagnosis. Body mass index should be the first stratification in the decision to perform endometrial biopsy and/or to refer secondary gynecology services. Copyright © 2016 Elsevier Inc

Abstract Background Although African American women have an overall lower incidence of breast cancer, African American women <40 years of age are more likely than Caucasian women of all ages and postmenopausal African American women to be diagnosed with breast cancer and exhibit tumor characteristics associated with poorer survival. To begin to address this disparity, studies must be conducted to examine breast cancer preventive factors in this subpopulation of women. However, the strategies needed to recruit younger African American women have not been well defined. Methods In this study, we assessed methods used for recruiting and retaining healthy premenopausal African American women into the African American Nutrition for Life (A NULIFE) Study. The number of women contacted, enrolled, and retained by each recruitment strategy and the efficiency of individual strategies were calculated. Results Overall, recruitment through social networking was most effective in contacting large numbers of healthy premenopausal African American women. The worksite recruitment method was the most efficient recruitment strategy employed, with a ratio of 40%. The study participants (n = 164) were more likely to be ≥35 years of age and have completed some college. Additionally, the interpersonal relationships recruitment approach proved most efficient (33%) in retaining participants who completed the yearlong study. Conclusions The findings from this study add to the evolving research literature on minority recruitment strategies for research studies but specifically address effective recruitment of healthy young premenopausal African American women. The results demonstrate the need to use multiple recruitment strategies when recruiting this subgroup of African American women. PMID:20392156

Complex metabolic changes cause obesity, making weight loss difficult. For this reason, understanding metabolism is important, and considering the shortcomings of conventional treatment options for obesity, acupuncture is a possible option. However, evidence supporting its efficacy on metabolic parameters in obese patients is lacking. The aim of this study is to investigate the effects of acupuncture on serum metabolic parameters in premenopausal obese women. This ongoing study is a randomized, patient-assessor blind, two-arm parallel non-penetrating sham-controlled clinical trial. Eligible participants, premenopausal adult women (19 years of age or older) with a clinical diagnosis of obesity (body mass index of 25 kg/m(2) or more) blinded to the treatment received, will be randomly allocated blindly into the real acupuncture treatment group (manual acupuncture plus electroacupuncture, n = 60) or the sham acupuncture control group (sham acupuncture plus placebo acupuncture without electrical stimulation, n = 60) and receive treatment two times a week for a total of 12 sessions over 6 weeks. The primary outcome measure is the serum cholesterol and triglyceride (TG) levels at baseline and endpoint. The secondary outcomes are body weight, body fat mass, muscle mass, waist and hip circumference, other serum metabolic profiles, International Physical Activity Questionnaire (IPAQ), Social Readjustment Rating Scale (SRRS), Stress Response Inventory (SRI), Fatigue Severity Scale (FSS), the Korean version of the Beck Depression Inventory (BDI), and urine metabolites. Adverse events will be assessed at every visit. The results of this trial (which will be available in 2015) will provide important clinical evidence for the effect of acupuncture on serum metabolites and demonstrate how acupuncture can be helpful for the treatment of obesity.

The premenopausal circulating lipid profile may be linked to the hormonal profile and ovarian lipid metabolism. Assess how estradiol, progesterone, and ovarian lipid metabolism contributes to the premenopausal lipid profile; and evaluate the acute effects of a common hormonal oral contraceptive (OC) on circulating lipids. Experimental crossover with repeated measures. Academic hospitals. Eight healthy, regularly menstruating women. Participants underwent periodic serum sampling during a normal menstrual cycle; a standard 21-day, monophasic combined hormonal OC cycle (30 µg of ethinyl estradiol and 150 µg of levonorgestrel per day); menopause simulated by leuprolide acetate (22.5-mg depot); and an artificial menstrual cycle achieved via transdermal estradiol (50 to 300 µg/d) and vaginal micronized progesterone (100 to 300 mg/d). Primary outcomes included evaluation of total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein cholesterol, triglycerides, and the total cholesterol to HDL cholesterol ratio. To estimate the effect of estradiol, progesterone, and ovarian lipid metabolism, all specimens except those from the OC cycle were analyzed. Subgroup analysis was conducted on the follicular and luteal phases. In a separate analysis, the effect of the OC was evaluated relative to the normal menstrual cycle. Estradiol was significantly associated with increased levels of HDL cholesterol throughout the menstrual cycle and in the follicular phase. Ovarian effects were associated with reduced lipid levels, especially during the luteal phase. The OC was associated with an increased total cholesterol to HDL cholesterol ratio and triglycerides. Previously unappreciated factors including ovarian lipid metabolism may contribute to the premenopausal lipid profile. Copyright © 2017 by the Endocrine Society

Several studies have reported increased fracture risk in Type 1 diabetes mellitus (T1DM). Quantitative Ultrasound (QUS) provides information on the structure and elastic properties of bone, which are important determinants of fracture risk, along with bone mineral density. To study phalangeal sites by QUS, examine bone turnover markers and analyze association between these factors with metabolic control in a population of pre-menopausal women with T1DM. Thirty-five T1DM pre-menopausal women (mean age 34.5 ± 6.8 yr) attending the Diabetic Outpatients Clinic in the Department of Internal Medicine, University of Messina, were consecutively enrolled and divided into two groups, taking into account the mean value of glycated hemoglobin in the last three years. Twenty healthy age-matched women served as controls. Phalangeal ultrasound measurements [Amplitude Dependent Speed of Sound (AD-SoS), Ultrasound Bone Profile Index (UBPI), TScore, Z-Score] were performed using a DBM Sonic Bone Profiler. Osteocalcin and deoxypyridinoline served as markers of bone formation and bone resorption, respectively. T1DM women with poor metabolic control showed lower phalangeal QUS values compared to healthy controls (p<0.01) and T1DM women with good metabolic control (p<0.05). No significant differences in QUS measurements were detected between T1DM women with good metabolic control and healthy controls. Lower bone formation and increased bone resorption, although not statistically significant, were observed in patients with poor metabolic control in comparison to patients with good metabolic control. Poor metabolic control may worsen the quality of bone in T1DM. Phalangeal QUS could be considered as a tool to screen T1DM women for osteoporosis in pre-menopausal age.

Mammographic density is one of the strong risk factors for breast cancer. A potential mechanism for this association is that cumulative exposure to mammographic density may reflect cumulative exposure to hormones that stimulate cell division in breast stroma and epithelium, which may have corresponding effects on breast cancer development. Bone mineral density (BMD), a marker of lifetime estrogen exposure, has been found to be associated with breast cancer. We examined the association between BMD and mammographic density in a Korean population. Study subjects were 730 Korean women selected from the Healthy Twin study. BMD (g/cm(2)) was measured with dual-energy X-ray absorptiometry. Mammographic density was measured from digital mammograms using a computer-assisted thresholding method. Linear mixed model considering familial correlations and a wide range of covariates was used for analyses. Quantitative genetic analysis was completed using SOLAR. In premenopausal women, positive associations existed between absolute dense area and BMD at ribs, pelvis, and legs, and between percent dense area and BMD at pelvis and legs. However, in postmenopausal women, there was no association between BMD at any site and mammographic density measures. An evaluation of additive genetic cross-trait correlation showed that absolute dense area had a weak-positive additive genetic cross-trait correlation with BMD at ribs and spines after full adjustment of covariates. This finding suggests that the association between mammographic density and breast cancer could, at least in part, be attributable to an estrogen-related hormonal mechanism.

To describe how Korean immigrant women tend to describe their work experiences within their daily lives and how they relate their work to the symptoms experienced during midlife. Cross-sectional study using methodological triangulation. Using a convenience sampling method, 119 Korean immigrant women were recruited for the quantitative phase, and 21 among the 119 women were recruited for the qualitative phase. Data were collected using both questionnaires and in-depth interviews. The data were analyzed using descriptive and inferential statistics and thematic analysis. FINDINGS AND DISCUSSIONS: The symptoms that the women experienced during midlife were influenced by their work experience, which was complicated by their cultural heritage, gender issues embedded in their daily lives, and immigration transition. Complexities and diversities in women's work need to be incorporated in menopausal studies.

The purpose of this study was to understand the health benefits of line dancing activity in Korean middle-aged women. This study explored how Korean middle-aged women perceive health benefits through lived experiences of line dancing in their leisure time. Three themes emerged related to health benefits: (1) psychological benefit, (2) physical benefit, and (3) social benefit. This finding suggested that serious leisure experience aids health enhancements in the lives of Korean middle-aged women. This study also discusses the research implication that continuous participation in leisure activity is necessary for health improvement in Korean middle-aged women.

Background Prior studies have found weak inverse associations between breast cancer and caffeine and coffee intake, possibly mediated through their effects on sex hormones. Methods High-performance liquid chromatography/tandem mass spectrometry was used to quantify levels of 15 individual estrogens and estrogen metabolites (EM) among 587 premenopausal women in the Nurses’ Health Study II with mid-luteal phase urine samples and caffeine, coffee and/or tea intakes from self-reported food frequency questionnaires. Multivariate linear mixed models were used to estimate geometric means of individual EM, pathways and ratios by intake categories, and P-values for tests of linear trend. Results Compared to women in the lowest quartile of caffeine consumption, those in the top quartile had higher urinary concentrations of 16α-hydroxyestrone (28% difference; P-trend=0.01) and 16-epiestriol (13% difference; P-trend=0.04), and a decreased parent estrogens/2-, 4-, 16-pathway ratio (P-trend=0.03). Coffee intake was associated with higher 2-catechols, including 2-hydroxyestradiol (57% difference, ≥4 cups/day vs. ≤6 cups/week; P-trend=0.001) and 2-hydroxyestrone (52% difference; P-trend=0.001), and several ratio measures. Decaffeinated coffee was not associated with 2-pathway metabolism, but women in the highest (vs. lowest) category of intake (≥2 cups/day vs. ≤1–3 cups/month) had significantly lower levels of two 16-pathway metabolites, estriol (25% difference; P-trend=0.01) and 17-epiestriol (48% difference; Ptrend=0.0004). Tea intake was positively associated with 17-epiestriol (52% difference; Ptrend=0.01). Conclusion Caffeine and coffee intake were both associated with profiles of estrogen metabolism in premenopausal women. Impact Consumption of caffeine and coffee may alter patterns of premenopausal estrogen metabolism. PMID:26063478

The acculturation process is an important factor in the experience of all immigrants. Although previous studies have indicated the challenges faced by Korean immigrants, little attention has been paid to Korean women's immigration experiences. A focused ethnography was used to examine midlife and older Korean immigrant women's experiences following their immigration to Canada. Fifteen women were interviewed in a city in Western Canada. The findings showed that in coming to Canada, women focused on caring for their children and often sacrificed their personal dreams. They had to be employed to support their families, and received support from family and government. Women participated regularly in a Korean Church and drew on their Christian faith to ease their adjustment. They retained hopes for the future including good health and a better life for their children. Most women indicated that it was difficult to integrate into Canadian society but they never gave up on their adjustment to a new culture. In this manuscript, the adjustment experience of the immigrant women is discussed in the context of an acculturation framework. The findings will enhance health professionals' awareness of adjustment patterns and associated challenges to Korean immigrant women's quality of life.

Objective. Examine the effects of exercise on femoral neck (FN) and lumbar spine (LS) bone mineral density (BMD) in premenopausal women. Methods. Meta-analysis of randomized controlled exercise trials ≥24 weeks in premenopausal women. Standardized effect sizes (g) were calculated for each result and pooled using random-effects models, Z score alpha values, 95% confidence intervals (CIs), and number needed to treat (NNT). Heterogeneity was examined using Q and I(2). Moderator and predictor analyses using mixed-effects ANOVA and simple metaregression were conducted. Statistical significance was set at P ≤ 0.05. Results. Statistically significant improvements were found for both FN (7g's, 466 participants, g = 0.342, 95%  CI = 0.132, 0.553, P = 0.001, Q = 10.8, P = 0.22, I(2) = 25.7%, NNT = 5) and LS (6g's, 402 participants, g = 0.201, 95%  CI = 0.009, 0.394, P = 0.04, Q = 3.3, P = 0.65, I(2) = 0%, NNT = 9) BMD. A trend for greater benefits in FN BMD was observed for studies published in countries other than the United States and for those who participated in home versus facility-based exercise. Statistically significant, or a trend for statistically significant, associations were observed for 7 different moderators and predictors, 6 for FN BMD and 1 for LS BMD. Conclusions. Exercise benefits FN and LS BMD in premenopausal women. The observed moderators and predictors deserve further investigation in well-designed randomized controlled trials.

Iron nutrition and premenopausal women: effects of poor iron status on physical and neuropsychological performance.

PubMed

McClung, James P; Murray-Kolb, Laura E

2013-01-01

Iron is a nutritionally essential trace element that functions through incorporation into proteins and enzymes, many of which contribute to physical and neuropsychological performance. Poor iron status, including iron deficiency (ID; diminished iron stores) and iron deficiency anemia (IDA; poor iron stores and diminished hemoglobin), affects billions of people worldwide. This review focuses on physical and neuropsychological outcomes associated with ID and IDA in premenopausal women, as the prevalence of ID and IDA is often greater in premenopausal women than other population demographics. Recent studies addressing the physiological effects of poor iron status on physical performance, including work productivity, voluntary activity, and athletic performance, are addressed. Similarly, the effects of iron status on neurological performance, including cognition, affect, and behavior, are summarized. Nutritional countermeasures for the prevention of poor iron status and the restoration of decrements in performance outcomes are described.

To perform a meta-analysis on the global prevalence of metabolic syndrome (MetS) in postmenopausal women. The meta-analysis also sought to measure the relationship menopause status has with MetS and its components. The Web of Science, Medline, PubMed, Scopus, Embase, CINAHL, DOAJ, and Google Scholar were all searched using the relevant keywords. Articles published during the period 2004 to 2017 that met our inclusion criteria and reported the prevalence of MetS among premenopausal and postmenopausal women were included. In the presence of heterogeneity, random-effects models were used to pool the prevalence and odds ratios (ORs), as measures of association in cross-sectional and comparative cross-sectional studies, respectively. The prevalence of MetS among postmenopausal women (119 studies [n = 95,115]) and the OR comparing the prevalence of MetS among postmenopausal and premenopausal women (23 studies [n = 66,801]) were pooled separately. The pooled prevalence of MetS among postmenopausal women was found to be 37.17% (95% confidence interval [CI] 35.00%-39.31%), but varied from 13.60% (95% CI 13.55%-13.64%) to 46.00% (95% CI 1.90%-90.09%), depending upon the diagnostic criteria used. The overall pooled OR for MetS in postmenopausal women, compared with premenopausal women, was OR 3.54 (95% CI 2.92-4.30), but this ranged from OR 2.74 (95% CI 1.32-5.66) to OR 5.03 (95% CI 2.25-11.22), depending upon the criteria used. Furthermore, the odds of high fasting blood sugar (OR 3.51, 95% CI 2.11-5.83), low high-density lipoprotein cholesterol (OR 1.45, 95% CI 1.03-2.03), high blood pressure (OR 3.95, 95% CI 2.01-7.78), high triglycerides (OR 3.2, 95% CI 2.37-4.31), and high waist circumference (OR 2.75, 95% CI 1.80-4.21) were all found to be higher in postmenopausal women than in premenopausal women. The prevalence of MetS is relatively high in postmenopausal women and was more prevalent among postmenopausal than premenopausal women. Menopausal hormone therapy

The aim of this study was to assess the impact of caloric restriction diet versus caloric restriction diet combined with aerobic exercises on bone mineral density (BMD) in obese premenopausal women. Forty premenopausal obese women were classified randomly into two groups equal in number. The first group (group A) received caloric restriction diet, while the second (group B) received caloric restriction diet combined with a program of aerobic exercises, over 3 months. The variables measured in this study included age, weight, height, body mass index, fat weight, lean mass, fat percent, basal metabolic rate, and BMD. The comparison between group A and group B showed significantly higher post-treatment lean mass, basal metabolic rate, and BMD in weight-bearing bones (L2-L4 lumbar spine and total hip) in group B compared to group A. In contrast to the BMD of the weight-bearing bones, the BMD of the radius showed significant decrease between the pre- and post-treatment results in groups A and B with no significant differences between the two groups. A greater improvement in the BMD of weight-bearing bones was observed in obese premenopausal women undergoing caloric restriction combined with exercise than in those not undergoing exercise. Anaerobic exercises incorporated into weight loss programs help offset the adverse effects of dietary restriction on bone.

Endometrial biopsies are undertaken in premenopausal women with abnormal uterine bleeding but the risk of endometrial cancer or atypical hyperplasia is unclear. To conduct a systematic literature review to establish the risk of endometrial cancer and atypical hyperplasia in premenopausal women with abnormal uterine bleeding. Search of PubMed, Embase and the Cochrane Library from database inception to August 2015. Studies reporting rates of endometrial cancer and/or atypical hyperplasia in women with premenopausal abnormal uterine bleeding. Data were independently extracted by two reviewers and cross-checked. For each outcome, the risk and a 95% CI were estimated using logistic regression with robust standard errors to account for clustering by study. Sixty-five articles contributed to the analysis. Risk of endometrial cancer was 0.33% (95% CI 0.23-0.48%, n = 29 059; 97 cases) and risk of endometrial cancer or atypical hyperplasia was 1.31% (95% CI 0.96-1.80, n = 15 772; 207 cases). Risk of endometrial cancer was lower in women with heavy menstrual bleeding (HMB) (0.11%, 95% CI 0.04-0.32%, n = 8352; 9 cases) compared with inter-menstrual bleeding (IMB) (0.52%, 95% CI 0.23-1.16%, n = 3109; 14 cases). Of five studies reporting the rate of atypical hyperplasia in women with HMB, none identified any cases. The risk of endometrial cancer or atypical hyperplasia in premenopausal women with abnormal uterine bleeding is low. Premenopausal women with abnormal uterine bleeding should first undergo conventional medical management. Where this fails, the presence of IMB and older age may be indicators for further investigation. Further research into the risks associated with age and the cumulative risk of co-morbidities is needed. Contrary to practice, premenopausal women with heavy periods or inter-menstrual bleeding rarely require biopsy. © 2016 The Authors BJOG An International Journal of Obstetrics and Gynaecology published by John Wiley & Sons Ltd on behalf of Royal

To determine the relationships between the percentage predicted cardiorespiratory fitness (%CRF) and the anthropometric and metabolic cardiovascular disease risk factors in asymptomatic, premenopausal women. Data are baseline values obtained in 97 healthy premenopausal women (age 49.9 +/- 1.9 years; body mass index 23.2 +/- 2.2 kg/m(2)) participating in a longitudinal study from 2004 to 2009. The outcome measures were peak oxygen consumption (VO(2) peak), body mass index, body composition (percentage fat, fat mass, fat-free mass), waist circumference, abdominal subcutaneous fat, visceral fat, resting blood pressure and fasting lipids, glucose and insulin levels. The %CRF was negatively associated with body mass index, fat mass, percentage fat, waist circumference, abdominal subcutaneous fat, visceral fat, triglycerides, triglyceride/high density lipoprotein cholesterol, total cholesterol, total cholesterol/high density lipoprotein cholesterol, fasting insulin levels and HOMA-IR (- 0.59 < or = r < or = - 0.20; 0.01 < p < 0.05) and positively associated with insulin sensitivity index (r = 0.23; p < 0.05). VO(2) peak was associated with the same variables; however, correlations were slightly better (- 0.70 < or = r < or = 0.30; 0.01 < p < 0.05). Stepwise multiple regression analysis showed that %CRF was only independently correlated with plasma triglyceride levels. The results of this study suggest that %CRF was not a major predictor of anthropometric and metabolic variables associated with an increased risk of cardiovascular disease in asymptomatic premenopausal women. Finally, the VO(2) peak is a better predictor than the %CRF to assess the risk of cardiovascular disease in asymptomatic premenopausal women.

Parenteral administration of peptide GnRH analogs is widely employed for treatment of endometriosis and fibroids and in assisted-reproductive therapy protocols. Elagolix is a novel, orally available nonpeptide GnRH antagonist. Our objective was to evaluate the safety, pharmacokinetics, and inhibitory effects on gonadotropins and estradiol of single-dose and 7-d elagolix administration to healthy premenopausal women. This was a first-in-human, double-blind, placebo-controlled, single- and multiple-dose study with sequential dose escalation. Fifty-five healthy, regularly cycling premenopausal women participated. Subjects were administered a single oral dose of 25-400 mg or placebo. In a second arm of the study, subjects received placebo or 50, 100, or 200 mg once daily or 100 mg twice daily for 7 d. Treatment was initiated on d 7 (+/-1) after onset of menses. Safety, tolerability, pharmacokinetics, and serum LH, FSH, and estradiol concentrations were assessed. Elagolix was well tolerated and rapidly bioavailable after oral administration. Serum gonadotropins declined rapidly. Estradiol was suppressed by 24 h in subjects receiving at least 50 mg/d. Daily (50-200 mg) or twice-daily (100 mg) administration for 7 d maintained low estradiol levels (17 +/- 3 to 68 +/- 46 pg/ml) in most subjects during late follicular phase. Effects of the compound were rapidly reversed after discontinuation. Oral administration of a nonpeptide GnRH antagonist, elagolix, suppressed the reproductive endocrine axis in healthy premenopausal women. These results suggest that elagolix may enable dose-related pituitary and gonadal suppression in premenopausal women as part of treatment strategies for reproductive hormone-dependent disease states.

Whereas it is established that organic pain may induce depression, it is unclear whether pain is more common in healthy subjects with depression. We assessed the prevalence of pain in premenopausal women with major depression (MDD). Subjects were 21- to 45-year-old premenopausal women with MDD (N = 70; age: 35.4 +/- 6.6; mean +/- SD) and healthy matched controls (N = 36; age 35.4 +/- 6.4) participating in a study of bone turnover, the P.O.W.E.R. (Premenopausal, Osteopenia/Osteoporosis, Women, Alendronate, Depression) Study. Patients received a clinical assessment by a pain specialist, which included the administration of two standardized forms for pain, the Brief Pain Inventory - Short Form, and the Initial Pain Assessment Tool, and two scales of everyday stressors, the Hassles and Uplifts Scales. In addition, a quality-of-life instrument, the SF-36, was used. The diagnosis of MDD was established by a semi-structured interview, according to the DSM-IV criteria. Substance P (SP) and calcitonin-gene-related-peptide (CGRP), neuropeptides which are known mediators of pain, were measured every hour for 24 h in a subgroup of patients (N = 17) and controls (N = 14). Approximately one-half of the women with depression reported pain of mild intensity. Pain intensity was significantly correlated with the severity of depression (r2 = 0.076; P = 0.04) and tended to be correlated with the severity of anxiety, (r2 = 0.065; P = 0.07), and the number of depressive episodes (r2 = 0.072; P = 0.09). Women with MDD complained of fatigue, insomnia, and memory problems and experienced everyday negative stressors more frequently than controls. Quality of life was decreased in women with depression, as indicated by lower scores in the emotional and social well-being domains of the SF-36. SP (P < 0.0003) and CGRP (P < 0.0001) were higher in depressed subjects. Women with depression experienced pain more frequently than controls, had a lower quality of life, and complained more of daily

To compare the efficacy of the oral dienogest versus triptorelin acetate injection for treatment of premenopausal menorrhagia and pelvic pains in women with uterine adenomyosis. A total of 41 patients with adenomyosis suffering from pelvic pains and menorrhagia were recruited. First group was managed with oral dienogest (2 mg/day, orally) while the second group received triptorelin acetate (3.75 mg/4 weeks, subcutaneous injection) for 16 weeks. Outpatient follow-up was undertaken after 8 weeks but mean values were calculated at baseline and after 16 weeks (end of treatment). A total of 41 women were allocated to treatment with dienogest (n = 22) or triptorelin acetate (n = 19); 19 (86.4 %) and 18 (94.7 %) % of the respective groups completed the trial. Significant reductions in pelvic pains after 16 weeks treatment were obtained in both groups demonstrating the equivalence of dienogest relative to triptorelin acetate. Triptorelin acetate was more effective in controlling of menorrhagia and reduction of uterine volume. Dienogest may be a valuable alternative to depot triptorelin acetate for treatment of premenopausal pelvic pains in women with uterine adenomyosis.

The aim of this study was to determine the treatment preferences (adjuvant goserelin or cyclophosphamide, methotrexate and fluorouracil (CMF) chemotherapy) of healthy premenopausal women should they hypothetically develop oestrogen-receptor (ER) positive early breast cancer. Two hundred pre or peri-menopausal women read two scenarios describing goserelin or chemotherapy. Information included: How and where treatments were administered, side-effects, their likely persistence and impact on fertility. Women stated their unprompted initial and final preferences with reasons for the choices made. Respondents showed an overwhelming preference for goserelin. 156 (78%) women favoured goserelin, 22 (11%) chemotherapy and 22 (11%) remained undecided (P<0.0001). Primary reasons for preferring goserelin for were 105 (71%) avoidance of chemotherapy side-effects, especially hair loss, perceived convenience and less disruption to normal life 54 (36%). The minority who preferred chemotherapy, valued the treatment finishing more quickly. These results together with clinical trial data showing equivalence of goserelin with CMF regimens suggest that premenopausal women with ER-positive tumours should at least be offered the choice of either adjuvant hormone therapy or chemotherapy.

An untold story in labor health: Korean women workers.

Very little is known about labor health among Korean women workers, who have been left behind by the occupational safety and health institutions. In this article, we examine, from a gender perspective, the occupational safety and health (OSH) statistics, institutions, and the struggles of women workers, and discuss how to make a society where women workers become and stay healthy. The problems Korean women workers face have both universal and unique aspects. On the one hand, they tend to be exposed to "invisible hazards" and to disproportionately suffer from neo-liberal policies, as do women workers in other countries. On the other hand, Korean women workers are still positioned under the strong patriarchy found in pre-modern societies. The examples of struggle presented here come out of this condition; those struggles by women workers and support from concerned specialists have played an important role in overcoming patriarchy and protecting health rights for women workers.

Objective. Examine the effects of exercise on femoral neck (FN) and lumbar spine (LS) bone mineral density (BMD) in premenopausal women. Methods. Meta-analysis of randomized controlled exercise trials ≥24 weeks in premenopausal women. Standardized effect sizes (g) were calculated for each result and pooled using random-effects models, Z score alpha values, 95% confidence intervals (CIs), and number needed to treat (NNT). Heterogeneity was examined using Q and I 2. Moderator and predictor analyses using mixed-effects ANOVA and simple metaregression were conducted. Statistical significance was set at P ≤ 0.05. Results. Statistically significant improvements were found for both FN (7g's, 466 participants, g = 0.342, 95%  CI = 0.132, 0.553, P = 0.001, Q = 10.8, P = 0.22, I 2 = 25.7%, NNT = 5) and LS (6g's, 402 participants, g = 0.201, 95%  CI = 0.009, 0.394, P = 0.04, Q = 3.3, P = 0.65, I 2 = 0%, NNT = 9) BMD. A trend for greater benefits in FN BMD was observed for studies published in countries other than the United States and for those who participated in home versus facility-based exercise. Statistically significant, or a trend for statistically significant, associations were observed for 7 different moderators and predictors, 6 for FN BMD and 1 for LS BMD. Conclusions. Exercise benefits FN and LS BMD in premenopausal women. The observed moderators and predictors deserve further investigation in well-designed randomized controlled trials. PMID:23401684

The aim of this study was to estimate tissue and gingival crevicular fluid (GCF) levels of the oxidative stress marker 8-hydroxy-2'-deoxyguanosine (8-OHdG) in premenopausal, perimenopausal and postmenopausal women with chronic periodontitis. Oxidative stress has been implicated in the etiopathogenesis of periodontitis and menopause induces oxidative stress. According to Stages of Reproductive Aging Workshop (STRAW) criteria, women diagnosed with periodontitis were subdivided into three groups of 31 participants each 1. Premenopausal 2. Perimenopausal and 3. Postmenopausal. GCF and gingival tissue samples were collected from sites with maximum probing depth. Tissue DNA was extracted from the gingival sample and 8-OHdG in the extracted DNA, and GCF samples were measured using ELISA. There was a highly significant difference in the overall GCF 8-OHdG levels among the three groups with the pairwise difference being highly significant between the premenopausal-postmenopausal groups and perimenopausal-postmenopausal groups. However, no overall significant differences in tissue 8-OHdG levels were found among the three groups. Pairwise, highly significant differences were found between the premenopausal-postmenopausal groups and perimenopausal-postmenopausal groups for tissue 8-OHdG levels. No significant correlations were found between various measure of periodontal disease and GCF/tissue 8-OHdG levels among all the groups. Premenopausal-postmenopausal and perimenopausal-postmenopausal transition resulted in significant increase in tissue and GCF 8-OHdG levels. However, no association was found between stages of reproductive ageing and tissue levels of 8-OHdG. © 2017 John Wiley & Sons A/S and The Gerodontology Association.

Adjuvant endocrine therapy for premenopausal women with hormone-responsive breast cancer.

PubMed

Mathew, Aju; Davidson, Nancy E

2015-11-01

Multiple strategies for endocrine treatment of premenopausal women with hormone-responsive breast cancer have been assessed and results have been presented over the last two years. These include tamoxifen for 5-10 years (ATLAS and aTTom), tamoxifen for 5 years followed by aromatase inhibitor (AI) for 5 years for women who have become postmenopausal (MA-17); ovarian ablation (OA) by surgery (EBCTCG overview); ovarian function suppression (OFS) by LHRH agonist (LHRH agonist meta-analysis); or combinations of approaches including OFS plus tamoxifen or AI (SOFT, TEXT, ABCSG 12 and E3193). Many of these trials have taken place in the backdrop of (neo)adjuvant chemotherapy which can confound interpretation because such therapy can suppress ovarian function either transiently or permanently. Nonetheless these trials suggest in aggregate that 10 years of tamoxifen are better than 5 years and that a program of extended adjuvant therapy of tamoxifen for 5 years followed by aromatase inhibitor for 5 years is effective for suitable candidates. The SOFT and E3193 trials do not show a major advantage for use of OFS + tamoxifen compared to tamoxifen alone. The joint SOFT/TEXT analysis and ABCGS12 trials both suggest that outcomes can be excellent with the use of combined endocrine therapy alone in properly selected patients but give conflicting results with regard to potential benefits for OFS + AI compared with OFS + tamoxifen. Further work will be needed to ascertain long-term outcomes, identify factors that predict who will benefit from extended adjuvant endocrine therapy, and assess role of OFS by medical or surgical means. It is clear, however, that endocrine therapy is a critical part of the adjuvant regimen for most premenopausal women with hormone-responsive breast cancer, and a subset of these women with luminal A-type tumors can be safely treated with endocrine therapy alone.

Background It is well accepted that exercise can decrease breast cancer risk. Limited clinical evidence suggests that this risk could be mediated through changes in estrogen metabolism in premenopausal women. Our objective was to investigate the effects of exercise on premenopausal estrogen metabolism pertinent to breast cancer risk. Methods Sedentary, healthy, young eumenorrheic women were randomized into an intervention of 30 minutes of moderate-to-vigorous aerobic exercise 5 times a week for approximately 16 weeks (n = 212), or into a usual-lifestyle sedentary control group (n = 179). Urinary levels of estrogens (estrone [E1], estradiol, and estriol) and nine estrogen metabolites were measured at baseline and at study end by liquid chromatography/tandem mass spectrometry. The ratios of 2-hydroxyestrone to 16α-hydroxyestrone (2-OHE1/16α-OHE1) and 2-OHE1 to 4-hydroxyestrone (2- OHE1/4-OHE1) were also calculated. Results The exercise intervention resulted in significant increases in aerobic fitness and lean body mass, and a significant decrease in percent body fat. For exercisers who completed the study (n = 165), 2-OHE1/16α-OHE1 increased significantly (P = 0.043), while E1 decreased significantly (P = 0.030) in control participants (n = 153). The change from baseline in 2-OHE1/16α-OHE1 was significantly different between groups (P = 0.045), even after adjustment for baseline values. Conclusions The exercise intervention resulted in a significant increase in the 2-OHE1/16α-OHE1 ratio, but no differences in other estrogen metabolites or ratios. Impact Our results suggest that changes in premenopausal estrogen metabolism may be a mechanism by which increased physical activity lowers breast cancer risk. PMID:23652373

In women with anorexia nervosa, elevated fasting peptide YY (PYY) is associated with decreased bone mineral density (BMD). Prior research from our lab has demonstrated that fasting total PYY concentrations are elevated in exercising women with amenorrhea compared to ovulatory exercising women. The purpose of this study was to assess the association between fasting total PYY, average monthly estrogen exposure and BMD in non-obese premenopausal exercising women. Daily urine samples were collected and assessed for metabolites of estrone 1-glucuronide (E1G) and pregnandiol glucuronide (PdG) for at least one menstrual cycle if ovulatory or a 28-day monitoring period if amenorrheic. Fasting serum samples were pooled over the measurement period and analyzed for total PYY and leptin. BMD and body composition were assessed by dual-energy X-ray absorptiometry. Multiple regression analyses were performed to determine whether measures of body composition, estrogen status, exercise minutes, leptin and PYY explained a significant amount of the variance in BMD at multiple sites. Premenopausal exercising women aged 23.8±0.9years with a mean BMI of 21.2±0.4kg/m(2) exercised 346±48min/week and had a peak oxygen uptake of 49.1±1.8mL/kg/min. Thirty-nine percent (17/44) of the women had amenorrhea. Fasting total PYY concentrations were negatively associated with total body BMD (p=0.033) and total hip BMD (p=0.043). Mean E1G concentrations were positively associated with total body BMD (p=0.033) and lumbar spine (L2-L4) BMD (p=0.047). The proportion of variance in lumbar spine (L2-L4) BMD explained by body weight and E1G cycle mean was 16.4% (R(2)=0.204, p=0.012). The proportion of variance in hip BMD explained by PYY cycle mean was 8.6% (R(2)=0.109, p=0.033). The proportion of variance in total body BMD explained by body weight and E1G cycle mean was 21.9% (R(2)=0.257, p=0.003). PYY, mean E1G and body weight are associated with BMD in premenopausal exercising women. Thus, elevated

Intake of sugar-sweetened beverages has increased in North America and seems to have several adverse health effects possibly through decreased circulating 25-hydroxyvitamin D (25(OH)D) concentrations. The aim of this cross-sectional study was to evaluate the association between sugar-sweetened beverages intake and 25(OH)D concentrations among premenopausal women. Intake of sugar-sweetened beverages including colas, other carbonated beverages and sweet fruit drinks was assessed using a validated food frequency questionnaire among 741 premenopausal women. Plasma concentrations of 25(OH)D were quantified by radioimmunoassay. The association between sugar-sweetened beverages intake and 25(OH)D concentrations was evaluated using multivariate generalized linear models and Spearman correlations. A higher intake of colas was associated with lower mean 25(OH)D levels (67.0, 63.7, 64.7 and 58.5 nmol/L for never, <1, 1–3 and >3 servings/week, respectively; r = −0.11 (p = 0.004)). A correlation was observed between intake of other carbonated beverages and 25(OH)D concentrations but was not statistically significant (r = −0.06 (p = 0.10)). No association was observed between intake of sweet fruit drinks and 25(OH)D concentrations. This study suggests that high intake of colas may decrease 25(OH)D levels in premenopausal women. Considering the high consumption of these drinks in the general population and the possible consequences of vitamin D deficiency on health, this finding needs further investigation. PMID:25072269

To evaluate the changes in mammographic density after tamoxifen discontinuation in premenopausal women with oestrogen receptor-positive breast cancers and the underlying factors METHODS: A total of 213 consecutive premenopausal women with breast cancer who received tamoxifen treatment after curative surgery and underwent three mammograms (baseline, after tamoxifen treatment, after tamoxifen discontinuation) were included. Changes in mammographic density after tamoxifen discontinuation were assessed qualitatively (decrease, no change, or increase) by two readers and measured quantitatively by semi-automated software. The association between % density change and clinicopathological factors was evaluated using univariate and multivariate regression analyses. After tamoxifen discontinuation, a mammographic density increase was observed in 31.9% (68/213, reader 1) to 22.1% (47/213, reader 2) by qualitative assessment, with a mean density increase of 1.8% by quantitative assessment compared to density before tamoxifen discontinuation. In multivariate analysis, younger age (≤ 39 years) and greater % density decline after tamoxifen treatment (≥ 17.0%) were independent factors associated with density change after tamoxifen discontinuation (p < .001 and p = .003, respectively). Tamoxifen discontinuation was associated with mammographic density change with a mean density increase of 1.8%, which was associated with younger age and greater density change after tamoxifen treatment. • Increased mammographic density after tamoxifen discontinuation can occur in premenopausal women. • Mean density increase after tamoxifen discontinuation was 1.8%. • Density increase is associated with age and density decrease after tamoxifen.

A hypothesized model of Korean women's responses to abuse.

PubMed

Choi, Myunghan; Harwood, Jake

2004-07-01

Many abused married Korean women have a strong desire to leave their abusive husbands but remain in the abusive situations because of the strong influence of their sociocultural context. The article discusses Korean women's responses to spousal abuse in the context of patriarchal, cultural, and social exchange theory. Age, education, and income as component elements share common effects on the emergent variable, sociostructural power. Gender role attitudes, traditional family ideology, individualism/collectivism, marital satisfaction, and marital conflict predict psychological-relational power as a latent variable. Sociostructural, patriarchal, cultural, and social exchange theories are reconceptualized to generate the model of Korean women's responses to abuse.

Context: Parenteral administration of peptide GnRH analogs is widely employed for treatment of endometriosis and fibroids and in assisted-reproductive therapy protocols. Elagolix is a novel, orally available nonpeptide GnRH antagonist. Objective: Our objective was to evaluate the safety, pharmacokinetics, and inhibitory effects on gonadotropins and estradiol of single-dose and 7-d elagolix administration to healthy premenopausal women. Design: This was a first-in-human, double-blind, placebo-controlled, single- and multiple-dose study with sequential dose escalation. Participants: Fifty-five healthy, regularly cycling premenopausal women participated. Interventions: Subjects were administered a single oral dose of 25–400 mg or placebo. In a second arm of the study, subjects received placebo or 50, 100, or 200 mg once daily or 100 mg twice daily for 7 d. Treatment was initiated on d 7 (±1) after onset of menses. Main Outcome Measures: Safety, tolerability, pharmacokinetics, and serum LH, FSH, and estradiol concentrations were assessed. Results: Elagolix was well tolerated and rapidly bioavailable after oral administration. Serum gonadotropins declined rapidly. Estradiol was suppressed by 24 h in subjects receiving at least 50 mg/d. Daily (50–200 mg) or twice-daily (100 mg) administration for 7 d maintained low estradiol levels (17 ± 3 to 68 ± 46 pg/ml) in most subjects during late follicular phase. Effects of the compound were rapidly reversed after discontinuation. Conclusions: Oral administration of a nonpeptide GnRH antagonist, elagolix, suppressed the reproductive endocrine axis in healthy premenopausal women. These results suggest that elagolix may enable dose-related pituitary and gonadal suppression in premenopausal women as part of treatment strategies for reproductive hormone-dependent disease states.

Although there is ample evidence supporting the effectiveness of physical activity in the prevention and treatment of osteoporosis, there are no previous studies to examine the effect of office-based brief high-impact exercise (HIE) on bone mineral density (BMD) in healthy premenopausal women. This study evaluated the effects of office-based HIE on BMD in healthy premenopausal Japanese women. Ninety-one healthy premenopausal women were randomized to receive stretching exercise (SE) or HIE (stretching, along with up to 5 × 10 vertical and versatile jumps) for 12 months. The BMD of the lumbar spine and proximal femur was measured using dual-energy X-ray absorptiometry. Several cardiovascular risk factors and leg strength also were assessed. An accelerometer-based recorder was used to measure daily impact loading in four 1-week samples. The progression of the HIE program was ensured by the accelerometer. Thirty-three women (71.7%) in the SE group and 34 (75.6%) in the HIE group completed the study. There was a significant difference in the change in the femoral neck BMD between the groups in favor of the HIE group [0.6% (95% CI: -0.4, 1.7) vs. -1.0% (95% CI: -2.2, 0.2)]. Adiponectin, LDL, HDL, and the leg strength of participants in both the groups improved during the intervention. These finding suggested that office-based brief HIE can be recommended for premenopausal women for preventing bone mineral loss.

The polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women. On the contrary, the prevalences of other disorders of androgen excess such as idiopathic hyperandrogenism and idiopathic hirsutism remain unknown. We aimed to obtain an unbiased estimate of the prevalence in premenopausal women of (i) signs of androgen excess and (ii) PCOS, idiopathic hyperandrogenism and idiopathic hirsutism. A multicenter prevalence survey included 592 consecutive premenopausal women (393 from Madrid, Spain and 199 from Bologna, Italy) reporting spontaneously for blood donation. Immediately before donation, we conducted clinical and biochemical phenotyping for androgen excess disorders. We determined the prevalence of (i) hirsutism, acne and alopecia as clinical signs of androgen excess and (ii) functional disorders of androgen excess, including PCOS, defined by the National Institute of Child Health and Human Development/National Institute of Health criteria, idiopathic hyperandrogenism and idiopathic hirsutism. Regarding clinical signs of hyperandrogenism, hirsutism and acne were equally frequent [12.2% prevalence; 95% confidence interval (CI): 9.5-14.8%], whereas alopecia was uncommon (1.7% prevalence, 95% CI: 0.7-2.7%). Regarding functional disorders of androgen excess, PCOS and idiopathic hirsutism were equally frequent (5.4% prevalence, 95% CI: 3.6-7.2) followed by idiopathic hyperandrogenism (3.9% prevalence, 95% CI: 2.3-5.4). Clinical signs of hyperandrogenism and functional disorders of androgen excess show a high prevalence in premenopausal women. The prevalences of idiopathic hyperandrogenism and idiopathic hirsutism are similar to that of PCOS, highlighting the need for further research on the pathophysiology, consequences for health and clinical implications of these functional forms of androgen excess.

Osteoporosis is a complex disease with both genetic and environmental risk factors. A major determinant of osteoporotic fractures is peak BMD obtained during young adulthood. We previously reported linkage of chromosome 1q (LOD = 4.3) with variation in spinal areal BMD in healthy premenopausal white women. In this study, we used a two-stage genotyping approach to identify genes in the linked region that contributed to the variation of femoral neck and lumbar spine areal BMD. In the first stage, 654 SNPs across the linked region were genotyped in a sample of 1309 premenopausal white women. The most significant evidence of association for lumbar spine (p = 1.3 × 10−6) was found with rs1127091 in the GATAD2B gene. In the second stage, 52 SNPs around this candidate gene were genotyped in an expanded sample of 1692 white women. Significant evidence of association with spinal BMD (p < 10−5), and to a lesser extent with femoral neck BMD, was observed with eight SNPs within a single 230-kb linkage disequilibrium (LD) block. The most significant SNP (p = 3.4 × 10−7) accounted for >2.5% of the variation in spinal BMD in these women. The 230-kb LD block contains 11 genes, but because of the extensive LD, the specific gene(s) contributing to the variation in BMD could not be determined. In conclusion, the significant association between spinal BMD and SNPs in the 230-kb LD block in chromosome 1q indicates that genetic factor(s) in this block plays an important role in peak spinal BMD in healthy premenopausal white women.

Sex hormones and breast cancer risk in premenopausal women: collaborative reanalysis of seven prospective studies

PubMed Central

2014-01-01

Background The relationships of circulating concentrations of oestrogens, progesterone and androgens with breast cancer and related risk factors in premenopausal women are not well understood. Methods Individual data on prediagnostic sex hormone and sex hormone binding globulin (SHBG) concentrations were contributed by 7 prospective studies. Analyses were restricted to women who were premenopausal and under age 50 at blood collection, and to breast cancer cases diagnosed before age 50. The odds ratios (ORs) with 95% confidence intervals (95% CIs) for breast cancer associated with hormone concentrations were estimated by conditional logistic regression in up to 767 cases and 1699 controls matched for age, date of blood collection, and day of cycle, with stratification by study and further adjustment for cycle phase. The associations of hormones with risk factors for breast cancer in control women were examined by comparing geometric mean hormone concentrations in categories of these risk factors, adjusted for study, age, phase of menstrual cycle and body mass index (BMI). All statistical tests were two-sided. Findings ORs for breast cancer associated with a doubling in hormone concentration were 1.19 (95% CI 1.06–1.35) for oestradiol, 1.17 (1.03–1.33) for calculated free oestradiol, 1.27 (1.05–1.54) for oestrone, 1.30 (1.10–1.55) for androstenedione, 1.17 (1.04–1.32) for dehydroepiandrosterone sulphate, 1.18 (1.03–1.35) for testosterone and 1.08 (0.97–1.21) for calculated free testosterone. Breast cancer risk was not associated with luteal phase progesterone (for a doubling in concentration OR=1.00 (0.92–1.09)), and adjustment for other factors had little effect on any of these ORs. The cross-sectional analyses in control women showed several associations of sex hormones with breast cancer risk factors. Interpretation Circulating oestrogens and androgens are positively associated with the risk for breast cancer in premenopausal women. PMID:23890780

Symptoms experienced during menopausal transition: Korean women in South Korea and the United States.

Im, Eun-Ok

2003-10-01

This article reports on cultural influences on symptoms experienced during menopausal transition of Korean women in South Korea and Korean immigrant women in the United States. Data from independent studies of two groups of Korean women were triangulated and analyzed using descriptive and inferential statistics. The analysis indicated that Korean women in South Korea tended to report more symptoms than Korean immigrant women in the United States. Types and severity of prevalent symptoms were also found to be different between the two groups. The findings suggest that recent introduction of menopausal industries in South Korea and contextual influences on Korean women's work and immigration in the United States would be the reason for differences. Based on the findings, implications for future research are proposed.

The relationship between dietary nutrients and plasma estrone, estradiol-17 beta, estriol, dehydroepiandrosterone sulfate, and prolactin levels was investigated in 14 premenopausal Seventh-day Adventist vegetarian (SV) women and 9 premenopausal non-Seventh-day Adventist nonvegetarian (NV) women. The SV subjects consumed less fat, especially saturated fat, and used significantly less fried food than the NV subjects. Plasma levels of estrone and estradiol-17 beta in the SV subjects were significantly lower than in the NV subjects. SV estradiol-17 beta and estriol levels were positively correlated with linoleic acid and protein intake, while NV prolactin levels were significantly correlated with intakes of oleic and linoleic acids and total fat. The data suggest that specific dietary nutrients were related to the hormonal milieu of these SV and NV subjects.

To examine the association between obesity and cognitive function in healthy premenopausal women. From a cohort of 220 women, 98 were randomly selected that provided complete data. Body composition was examined by dual-energy X-ray scan. All participants completed the Cambridge Neuropsychological Test Automated Battery (CANTAB) to assess cognitive performance in three domains: attention, memory, and planning executive function. The Reaction Time (RTI) test was used to assess motor and mental response speeds; the Stockings of Cambridge (SOC) test was used to assess planning executive function. For memory assessment, the Delayed Match to Sample (DMS), Pattern Recognition Memory (PRM), and Spatial Span (SSP) tests were used to assess forced choice recognition memory, visual pattern recognition memory, and working memory capacity, respectively. 36 (36.7%) were morbidly obese, 22 (22.4%) obese, and 23 (23.5%) overweight. Performance on RTI and SOC planning ability were not associated with body mass index (BMI). DMS mean time to correct response, when stimulus is visible or immediately hidden (0 ms delay), was higher by 785 ± 302 ms (milliseconds) ( p =0.011) and 587 ± 259 ms ( p =0.026) in morbidly obese women compared to normal weight women. Memory span length was significantly lower in overweight (5.5 ± 1.3, p =0.008) and obese women (5.6 ± 1.6, p =0.007) compared to normal weight (6.7 ± 0.9). DEXA-assessed body fat (%) showed similar associations as BMI, and latency to correct response on DMS and PRM was positively correlated with percentage of body fat, but not with VO 2 max. In otherwise healthy premenopausal women, obesity did not impact accuracy on cognitive tasks related to attention, memory, or planning executive function, but morbid obesity was associated with higher latency to correct response on memory-specific tasks and lower memory span length.

Cognitive deficits have been reported as detrimental side effects in chemotherapy-treated breast cancer patients and survivors. Korean women treated for breast cancer may experience unrecognized cognitive deficits related to their treatment. However, no research has examined cognitive test performance in chemotherapy-treated Korean breast cancer survivors. The objectives of this study were 2-fold: (1) to examine differences in occurrence and severity of cognitive deficits in Korean women treated with adjuvant chemotherapy for breast cancer as compared with a control group of women without breast cancer and (2) to examine the relationship of selected demographic and cultural factors with cognitive test performance. Sixty-four Korean women, 32 women treated for localized breast cancer and 32 healthy controls, were enrolled. Breast cancer participants were assessed with established cognitive measures within 4 months after chemotherapy, and healthy controls, within 6 months after negative screening mammography. The breast cancer group showed a significantly higher occurrence and greater severity of cognitive deficits than controls did. Importantly, older age, less education, greater collectivist tendency, and greater childrearing burden were reliably associated with poorer attention and working memory test performance. Cognitive deficits were found in chemotherapy-treated Korean women with moderate to large effect sizes compared with controls. Cultural characteristics contributed to worse cognitive performance. Healthcare providers should recognize that Korean women may be highly vulnerable to cognitive deficits. Cultural factors also need to be considered when assessing cognitive function and designing therapeutic interventions to counteract negative cognitive outcomes.

To explore Korean American women's symbolic meanings related to their breasts and cervix, to examine attitudes and beliefs about breast and cervical cancer, and to find relationships between the participants' beliefs and their cancer screening behaviors. Descriptive, qualitative analysis. Southwestern United States. 33 Korean-born women at least 40 years of age. In-depth, face-to-face, individual interviews were conducted in Korean. A semistructured interview guide was used to ensure comparable core content across all interviews. Transcribed and translated interviews were analyzed using descriptive content analysis. Breast cancer, cervical cancer, cancer screening, beliefs, and Korean American women. Korean American women's symbolic meaning of their breasts and cervix are closely related to their past experiences of bearing and rearing children. Negative life experiences among older Korean American women contributed to negative perceptions about cervical cancer. Having information about cancer, either correct or incorrect, and having faith in God or destiny may be barriers to obtaining screening tests. Korean American women's symbolic meanings regarding their breasts and cervix, as well as their beliefs about breast cancer and cervical cancer and cancer screening, are associated with their cultural and interpersonal contexts. Their beliefs or limited knowledge appear to relate to their screening behaviors. Interventions that carefully address Korean American women's beliefs about breast cancer and cervical cancer as well as associated symbolic meanings may increase their cancer screening behaviors. Clinicians should consider Korean American women's culture-specific beliefs and representations as well as their life experiences in providing care for the population.

Abstract Background: Flibanserin, a 5-HT1A agonist and 5-HT2A antagonist, is indicated for the treatment of acquired, generalized hypoactive sexual desire disorder (HSDD) in premenopausal women. This post hoc analysis evaluated the effect of flibanserin treatment on body weight in premenopausal and postmenopausal women with HSDD. Materials and Methods: This analysis included three 24-week, double-blind, placebo-controlled studies of flibanserin 100 mg each bedtime (qhs) in premenopausal women, a similarly designed study in postmenopausal women, and a 52-week, open-label extension study in premenopausal women. Results: In a pooled analysis of premenopausal women, mean baseline body mass index (BMI) was 27.0 kg/m2 in the flibanserin group (n = 1227) and 26.8 kg/m2 in the placebo group (n = 1238). Among patients who completed 24 weeks of treatment, least squares (LS) mean weight change was −1.4 kg in the flibanserin group (n = 1010) and −0.1 kg in the placebo group (n = 1066; p < 0.0001). Weight loss ≥5% from baseline was reported in 21.0% of patients who received flibanserin and 7.8% of patients who received placebo; weight loss ≥10% was reported in 3.8% and 2.0% of patients, respectively. In postmenopausal women, mean baseline BMI was 27.7 kg/m2 in the flibanserin group (n = 467) and 27.3 kg/m2 in the placebo group (n = 480). LS mean weight change at week 24 was −1.8 kg in the flibanserin group (n = 385) and −0.1 kg in the placebo group (n = 425; p < 0.0001), with weight loss ≥5% reported in 24.7% and 7.3% of patients, respectively, and weight loss ≥10% reported in 5.2% and 1.7%, respectively. In HSDD patients with >12 months (n = 880) and >18 months (n = 637) of exposure to flibanserin, mean weight change was −1.0 and −1.2 kg, respectively; 25.4% and 26.9% of patients, respectively, experienced weight loss ≥5% from baseline, and 7.8% and 8.4%, respectively, experienced weight

The association between fruit and vegetable (FV) intake and risk of the metabolic syndrome (MetS) has not been elucidated fully, particularly by menopausal status. Method and Study Design: The study population was 2,999 women aged 40-64 years participating in the 4th Korea National Health and Nutrition Examination Survey. The definition of MetS and its components was based on the modified National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) for Koreans. Dietary data were assessed by a 24-hour recall. Fruit intake was inversely related only to the risk of high blood pressure (BP), but not MetS. Total vegetable consumption was inversely associated with the MetS risk, and when combined with fruits, the inverse association was observed even in its features of high triglycerides (TG) and low HDLcholesterol as well as MetS. Assessing women by menopausal status revealed that the inverse association with the MetS risk was found only in postmenopausal women having greater total vegetables and total FV intake (aOR=0.47, 95% CI=0.29-0.75, p-trend=0.003 and aOR=0.54, 95% CI=0.35-0.85, p-trend=0.007, respectively). Analysis regarding MetS features showed that while the inverse association of total vegetables or total FV intake was observed with high TG risk in postmenopausal women, fruits intake was inversely associated with high BP risk in premenopausal women (aOR=0.54, 95% CI=0.37-0.79, p-trend=0.004). Results suggest that while fruit intake was inversely associated with high BP in premenopausal women, greater dietary intake of vegetables and total FV may protect against the risk of MetS, particularly in postmenopausal women.

To understand Korean immigrant women's common experiences and practices of utilizing health care services in the United States during childbirth. A qualitative interpretive phenomenological research design. Recruitment was conducted through advertisement on the MissyUSA.com website, which is the largest online community for married Korean women who live in North America. A purposive sample of 15 Korean immigrant women who experienced childbirth in the United States within the past 5 years was recruited. Data were collected using semistructured telephone interviews and were analyzed using the Heideggerian hermeneutical methodology. During childbirth in the United States, participants faced multifaceted barriers in unfamiliar sociocultural contexts yet maintained their own cultural heritages. They navigated the unfamiliar health care system and developed their own strategies to overcome barriers to health care access. Korean immigrant women actively sought health information on the Internet and through social networking during childbirth. Korean immigrant women selectively accepted new cultural beliefs with some modifications from their own cultural contexts and developed their own distinct birth cultures. Understanding a particular culture and respecting women's traditions, beliefs, and practices about their childbirth could help nurses to provide culturally sensitive care. © 2014 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

There is limited research on the association between sedentary behaviour and breast cancer risk, particularly whether sedentary behaviour is differentially associated with premenopausal and postmenopausal breast cancer. We pooled data from 2 case-control studies from Australia and Canada to investigate this association. This pooled analysis included 1762 incident breast cancer cases and 2532 controls. Participants in both studies completed a lifetime occupational history and self-rated occupational physical activity level. A job-exposure matrix (JEM) was also applied to job titles to assess sedentary work. Logistic regression analyses (6 pooled and 12 study-specific) were conducted to estimate associations between both self-reported and JEM-assessed sedentary work and breast cancer risk among premenopausal and postmenopausal women. No association was observed in the 6 pooled analyses, and 10 of the study-specific analyses also showed null results. 2 study-specific analyses provided inconsistent and contradictory results, with 1 showing statistically significant increased risk of breast cancer for self-reported sedentary work among premenopausal women cancer in the Canadian study, and the other a non-significant inverse association between JEM-assessed sedentary work and breast cancer risk among postmenopausal women in the Australian study. While a suggestion of increased risk was seen for premenopausal women in the Canadian study when using the self-reported measure, overall this pooled study does not provide evidence that sedentary work is associated with breast cancer risk.

Black women experience higher rates of hysterectomy than other women in the United States. Although research indicates that premenopausal hysterectomy with bilateral oophorectomy decreases the risk of breast cancer in black women, it remains unclear how hysterectomy without ovary removal affects risk, whether menopausal hormone therapy use attenuates inverse associations, and whether associations vary by cancer subtype. In the population-based, case-control Carolina Breast Cancer Study of invasive breast cancer in 1,391 black (725 cases, 666 controls) and 1,727 white (939 cases, 788 controls) women in North Carolina (1993–2001), we investigated the associations of premenopausal hysterectomy and oophorectomy with breast cancer risk. Compared with no history of premenopausal surgery, bilateral oophorectomy and hysterectomy without oophorectomy were associated with lower odds of breast cancer (for bilateral oophorectomy, multivariable-adjusted odds ratios = 0.60, 95% confidence interval: 0.47, 0.77; for hysterectomy without oophorectomy, multivariable-adjusted odds ratios = 0.68, 95% confidence interval: 0.55, 0.84). Estimates did not vary by race and were similar for hormone receptor–positive and hormone receptor–negative cancers. Use of estrogen-only menopausal hormone therapy did not attenuate the associations. Premenopausal hysterectomy, even without ovary removal, may reduce the long-term risk of hormone receptor–positive and hormone receptor–negative breast cancers. Varying rates of hysterectomy are a potentially important contributor to differences in breast cancer incidence among racial/ethnic groups. PMID:27555487

The prevalence of cardiovascular diseases in women increases sharply after menopause. In postmenopausal women, thromboxane production increases while prostacyclin decreases. Low dose aspirin reduces the production of both thromboxane and prostacyclin. The present study was an open-label clinical trial with two parallel groups of 15 premenopausal women and 15 postmenopausal women. Twenty-four hours urine was collected from each subject before and after aspirin 100 mg daily for 7 days. The concentration of thromboxane and prostacyclin was measured as their metabolites (11-dehydro-thromboxane B(2) and 2,3-dinor-6-keto-prostaglandin-F(1α)) in urine using enzyme immunoassay methods. This study showed that aspirin significantly reduced thromboxane in both groups with significantly larger percentage reduction in postmenopausal women compared to premenopausal women (73.32 vs. 61.13%, p = 0.021). This study also showed that aspirin reduced prostacyclin significantly in both groups, but the percentage reduction between the groups was not significantly different. The decrease in the ratio of 11-dTXB(2)/2,3-dinor-6-keto-PGF(1α) should be compared to assess aspirin efficacy as an antithrombotic. Calculation of the ratio of 11-dTXB(2)/2,3-dinor-6-keto-PGF(1α) before aspirin consumption was higher in postmenopausal women than in premenopausal women. The decrease in 11-dTXB(2)/2,3-dinor-6-keto-PGF(1α) ratio by aspirin was greater in postmenopausal women than in premenopausal women (1.91 vs. 0.17; p = 0.022). It was concluded that aspirin reduced thromboxane and prostacyclin significantly in each group with significant 11-dTXB(2) percentage reduction between groups and non-significant 2,3-dinor-6-keto-PGF(1α) percentage reduction between groups, but reduced the 11-dTXB(2)/2,3-dinor-6-keto-PGF(1α) ratio much larger in postmenopausal women compared to that in premenopausal women.

The present study examined the effects of short-term recreational football training on blood pressure (BP), fat mass, and fitness in sedentary, 35-50-year-old premenopausal women with mild hypertension. Forty-one untrained, hypertensive women were randomized into a football training group (n = 21; FTG) and a control group (n = 20; CON). FTG performed 45 ± 1 1-h small-sided football training sessions during the 15-week intervention period. BP, body composition (dual-energy x-ray absorptiometry), blood lipid profile, and fitness level were determined pre- and post-intervention. After 15 weeks, systolic and diastolic BP, respectively, were lowered more (P < 0.05) in FTG (-12 ± 3 and -6 ± 2 mmHg) than in CON (-1 ± 1 and 1 ± 2 mmHg). Total body fat mass decreased more (P < 0.05) in FTG than in CON during the 15-week intervention period (-2.3 ± 0.5 kg vs 0.4 ± 0.3 kg). After 15 weeks, both total cholesterol (-0.4 ± 0.1 mmol/L vs 0.1 ± 0.2 mmol/L) and triglyceride (-0.2 ± 0.1 mmol/L vs 0.3 ± 0.2 mmol/L) were lowered more (P < 0.05) in FTG than in CON. Yo-Yo intermittent endurance level 1 test performance increased more (P < 0.05) in FTG than in CON (111 ± 18% vs 1 ± 3%) during the 15-week intervention period. In conclusion, short-term football training resulted in a marked reduction in BP and induced multiple improvements in fitness and cardiovascular health profile of untrained, premenopausal women with mild hypertension. © 2014 John Wiley & Sons A/S.

To identify reproductive, lifestyle, hormonal, and other correlates of circulating antimüllerian hormone (AMH) concentrations in mostly late premenopausal women. Cross-sectional study. Not applicable. A total of 671 premenopausal women not known to have cancer. None. Concentrations of AMH were measured in a single laboratory using the picoAMH ELISA. Multivariable-adjusted median (and interquartile range) AMH concentrations were calculated using quantile regression for several potential correlates. Older women had significantly lower AMH concentrations (≥40 [n = 444] vs. <35 years [n = 64], multivariable-adjusted median 0.73 ng/mL vs. 2.52 ng/mL). Concentrations of AMH were also significantly lower among women with earlier age at menarche (<12 [n = 96] vs. ≥14 years [n = 200]: 0.90 ng/mL vs. 1.12 ng/mL) and among current users of oral contraceptives (n = 27) compared with never or former users (n = 468) (0.36 ng/mL vs. 1.15 ng/mL). Race, body mass index, education, height, smoking status, parity, and menstrual cycle phase were not significantly associated with AMH concentrations. There were no significant associations between AMH concentrations and androgen or sex hormone-binding globulin concentrations or with factors related to blood collection (e.g., sample type, time, season, and year of blood collection). Among premenopausal women, lower AMH concentrations are associated with older age, a younger age at menarche, and currently using oral contraceptives, suggesting these factors are related to a lower number or decreased secretory activity of ovarian follicles.

Ultrasonography of adnexal causes of acute pelvic pain in pre-menopausal non-pregnant women

Dupuis, Carolyn S.; Kim, Young H.

2015-01-01

Acute-onset pelvic pain is an extremely common symptom in premenopausal women presenting to the emergency department. After excluding pregnancy in reproductive-age women, ultrasonography plays a major role in the prompt and accurate diagnosis of adnexal causes of acute pelvic pain, such as hemorrhagic ovarian cysts, endometriosis, ovarian torsion, and tubo-ovarian abscess. Its availability, relatively low cost, and lack of ionizing radiation make ultrasonography an ideal imaging modality in women of reproductive age. The primary goal of imaging in these patients is to distinguish between adnexal causes of acute pelvic pain that may be managed conservatively or medically, and those requiring emergency/urgent surgical or percutaneous intervention.

Can bone loss be reversed by antithyroid drug therapy in premenopausal women with Graves' disease?

PubMed Central

2010-01-01

Context Hyperthyroidism can lead to reduced bone mineral density (BMD) and increased fracture risk particularly in postmenopausal women, but the mechanism behind is still unclear. Objective Prospective examination of the influence of thyroid hormones and/or thyroid autoantibodies on BMD in premenopause. Design We have examined 32 premenopausal women with untreated active Graves' disease from time of diagnosis, during 18 months of antithyroid drug therapy (ATD) and additionally 18 months after discontinuing ATD. Variables of thyroid metabolism, calcium homeostasis and body composition were measured every 3 months. BMD of lumbar spine and femoral neck were measured at baseline, 18 ± 3 and 36 ± 3 months. Data were compared to base line, a sex- and age matched control group and a group of patients with Hashimoto's thyroiditis treated with non-suppressive doses of levothyroxine. Results The study showed significantly (p < 0.002) lower BMD in the thyrotoxic state compared to the control group with subsequent significant improvement during 18 ± 3 months of ATD compared to baseline (p < 0.001). However, during the following 18 months after stopping ATD femoral neck BMD decreased again unrelated to age (more than 0.4% per year, p < 0,002). The wellestablished effect of thyrotoxicosis on calcium homeostasis was confirmed. The positive predictor for best BMD was TSH receptor antibodies (TRAb) while free T4 correlated negatively in the thyrotoxic female Graves' patients (p < 0.02 and p < 0.003). In healthy controls and patients with treated Graves' disease both TSH and T4 correlated negatively to the bone mass (BMC) (p < 0.003). Conclusion The results indicated a clinically relevant impact of thyroid function on bone modulation also in premenopausal women with Graves' disease, and further indicated the possibility for a direct action of TRAb on bones.

Studies indicate ethnic differences in incidence, mortality, and survival rate of breast cancer. Despite the low incidence rate of breast cancer among the Korean population, Koreans are reported to be less likely to survive breast cancer. In this article, using a feminist perspective, the reasons why Korean women have been reported to be less likely to survive breast cancer are analyzed through a critical review of research among Korean women. A total of 469 studies (145 unpublished master's theses and doctoral dissertations and 324 articles published in South Korea and in the United States) were reviewed, analyzed, and critiqued in terms of biases present in the research process. Through a feminist critique of the literature, four possible reasons are proposed: androcentric views and assumptions underlying the research, modesty issues imbedded in Korean culture, the victim-blaming tendency of Korean culture, and intense emotions without adequate support.

Breast cancer incidence rates are low but rising in urban Mongolia. We collected reproductive and lifestyle factor information and measured anthropometrics and serum sex steroid concentrations among 314 premenopausal women living in Ulaanbaatar, Mongolia. Mean differences in hormone concentrations by these factors were calculated using age-adjusted quadratic regression splines. Estrone and estradiol in college-educated women were, respectively, 18.2% (p = 0.03) and 23.6% (p = 0.03) lower than in high-school-educated women. Progesterone concentrations appeared 55.8% lower (p = 0.10) in women residing in modern housing compared with women living in traditional housing (gers), although this finding was not statistically significant. Testosterone concentrations were positively associated with adiposity and central fat distribution; 17.1% difference (p = 0.001) for highest vs. lowest quarter for body mass index and 15.1% difference (p = 0.005) for waist-to-height ratio. Estrogens were higher in the follicular phase of women who breastfed each child for shorter durations. A distinct hormonal profile was associated with an urban lifestyle in premenopausal, Mongol women. In particular, heavier, more-educated women living in urban dwellings had higher testosterone and lower estrogen and progesterone levels. Higher breast cancer incidence in urban compared with rural women suggest that the hormonal profile associated with a more traditional lifestyle may be protective among Mongol women. PMID:27809264

Aim: Evaluate efficacy/safety of bremelanotide (BMT), a melanocortin-receptor-4 agonist, to treat female sexual dysfunctions in premenopausal women. Methods: Patients randomized to receive placebo or BMT 0.75, 1.25 or 1.75 mg self-administered subcutaneously, as desired, over 12 weeks. Primary end point was change in satisfying sexual events/month. Secondary end points included total score changes on female sexual function index and female sexual distress scale-desire/arousal/orgasm. Results: Efficacy data, n = 327. For 1.25/1.75-mg pooled versus placebo, mean changes from baseline to study end were +0.7 versus +0.2 satisfying sexual events/month (p = 0.0180), +3.6 versus +1.9 female sexual function index total score (p = 0.0017), −11.1 versus −6.8 female sexual distress scale-desire/arousal/orgasm total score (p = 0.0014). Adverse events: nausea, flushing, headache. Conclusion: In premenopausal women with female sexual dysfunctions, self-administered, as desired, subcutaneous BMT was safe, effective, and well tolerated (NCT01382719). PMID:27181790

Ovarian failure and cancer treatment: Incidence and interventions for premenopausal women

DOE Office of Scientific and Technical Information (OSTI.GOV)

Feldman, J.E.

Ovarian failure may be a long-term consequence of cancer treatment for premenopausal women. Caused by several treatments, including radiation therapy and the alkylating agents, it produces signs and symptoms associated with menopause: hot flashes, amenorrhea, dyspareunia, loss of libido, and irritability. Critical factors that determine ovarian functioning after treatment for cancer are the patient's age at the time of therapy, the amount of radiation that the ovaries received, and the dose of the antineoplastic agent(s). Medical interventions, such as hormonal therapy and surgical repositioning of the ovaries, may maintain ovarian function for some women. Nursing intervention includes assessment, education, andmore » counseling. Counseling focuses on how the prematurely menopausal patient feels about herself as indicated by self-esteem, body image, and sexuality.« less

Ultrasonography has been extensively used in women suspected of having a gynecological malignancy. The aim of this study is to evaluate the efficacy of 3D ultrasonography and power Doppler for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding. This cross-sectional study included 78 premenopausal women with abnormal uterine bleeding scheduled for hysteroscopy and endometrial curettage. The endometrial thickness (ET), uterine artery pulsatility index (PI) and resistance index (RI), and endometrial volume (EV) and 3D power Doppler vascularization index (VI), flow index (FI), and vascularization flow index (VFI) were measured and compared with hysteroscopic and histopathologic findings. The ET (P <0.001), EV (P <0.001), and endometrial VI (P <0.001) and VFI (P = 0.043) were significantly increased in patients with atypical endometrial hyperplasia and endometrial carcinoma (n = 10) than those with benign endometrium (n = 68); whereas, the uterine artery PI and RI and endometrial FI were not significantly different between the two groups. The best marker for discrimination between benign and malignant endometrium was the VI with an area under the ROC curve of 0.88 at a cutoff value of 0.81%. 3D ultrasonography and power Doppler, especially endometrial VI, may be useful for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding.

The purpose of this study was to understand and describe the illness experience of married Korean women with epilepsy. Data were collected during 2015~2016 through individual in-depth interviews with 12 married women with epilepsy. Verbatim transcripts were analyzed using Giorgi's phenomenological analysis to uncover the meaning of the illness experience of the participants. The study results showed that the illness experience of married Korean women with epilepsy was clustered into a specific description of situated structure and a general description of situated structure. Six themes from 20 meaning units were identified: 1) Undermined self-esteem with stigma of being epileptic; 2) Limited social interaction; 3) Suffering sorrow as a 'disqualified being'; 4) Shuttling back and forth across the boundary between healthy and epileptic; 5) Desperate struggle to meet the expectation of given role; 6) Self-empowering through self-restriction and realization. The findings from this study show that both the enacted and felt stigma of epilepsy impact on the life of married Korean women with epilepsy. Although the participants face social and interpersonal restriction and prejudices, they try their best to fulfill their role rather than to be cared for as patients. As the stigma and hardships of the participants are related to lack of knowledge, health professionals should focus not just on clinical intervention but also on providing targeted educational programs and counseling for these women to dispel the stigma of the disease and to increase their quality of life. © 2017 Korean Society of Nursing Science

Our objective was to assess the effects of differing modes of impact exercise on bone density at the hip and spine in premenopausal women through systematic review and meta-analysis. Electronic databases, key journals and reference lists were searched for controlled trials investigating the effects of impact exercise interventions on lumbar spine (LS), femoral neck (FN) and total hip (TH) bone mineral density (BMD) in premenopausal women. Exercise protocols were categorised according to impact loading characteristics. Weighted mean difference (WMD) meta-analyses were undertaken. Heterogeneity amongst trials was assessed. Fixed and random effects models were applied. Inspection of funnel plot symmetry was performed. Trial quality assessment was also undertaken. Combined protocols integrating odd- or high-impact exercise with high-magnitude loading (resistance exercises), were effective in increasing BMD at both LS and FN [WMD (fixed effect) 0.009 g cm(-2) 95% CI (0.002-0.015) and 0.007 g cm(-2) 95% CI (0.001-0.013); P = 0.011 and 0.017, respectively]. High-impact only protocols were effective on femoral neck BMD [WMD (fixed effect) 0.024 g cm(-2) 95% CI (0.002-0.027); P < 0.00001]. Funnel plots showed some asymmetry for positive BMD outcomes. Insufficient numbers of protocols assessing TH BMD were available for assessment. Exercise programmes that combine odd- or high-impact activity with high-magnitude resistance training appear effective in augmenting BMD in premenopausal women at the hip and spine. High-impact-alone protocols are effective only on hip BMD in this group. However, diverse methodological and reporting discrepancies are evident in published trials.

The aim of this study was to compare the diagnostic effectiveness of transvaginal sonography (TVS), saline infusion sonohysterography (SIS), and diagnostic hysteroscopy (HS), with the pathologic specimen as a gold standard diagnostic method, in detecting endometrial pathology in premenopausal women with abnormal uterine bleeding. This prospective cohort study was conducted at Zeynep Kamil Education and Training Hospital, Istanbul, Turkey, and included 89 premenopausal women. All participants were examined first by TVS, further investigated with SIS and HS, and finally dilatation and curettage was performed when needed. The results obtained from these three methods were compared with the pathologic diagnoses. The positive and negative likelihood ratios (LR+ and LR-) of TVS, SIS and HS were calculated by comparison with the final pathological diagnosis. In addition, area under the curve (AUC) values were also calculated. Polypoid lesion was the most common abnormal pathology. LR+ and LR- of TVS, SIS, and HS were 3.13 and 0.15, 9.83 and 0.07, 13.7 and 0.02 respectively in detection of any abnormal pathology, and the AUCs of TVS, SIS, and HS were 0.804, 0.920, and 0.954 respectively. When the three procedures were compared with each other separately, HS had the best diagnostic accuracy, and the diagnostic accuracy of HS and SIS was superior to TVS (p(1)=0.000, p(2)=0.000). For the detection of polypoid lesions, HS was the most accurate diagnostic procedure (AUC=0.947), followed by SIS (AUC=0.894) and TVS (AUC=0.778). HS provides the most accurate diagnosis and allows treatment in the same session in premenopausal women with abnormal uterine bleeding. Published by Elsevier Ireland Ltd.

Background Lesbian and bisexual women may be at greater risk of breast cancer than heterosexual women during the premenopausal period due to disparities in risk factors. Methods With 16 years of prospective data from a large cohort of U.S. women ages 25–58 years, we conducted a breast cancer risk assessment for 87,392 premenopausal women by applying the Rosner-Colditz biomathematical risk-prediction model to estimate breast cancer risk based on known risk factors. Based on each woman’s comprehensive risk factor profile, we calculated the predicted one-year incidence rate (IR) per 100,000 person-years and estimated incidence rate ratios (IRR) and 95% confidence intervals (CI) for lesbian and bisexual women compared to heterosexual women. Results 87,392 premenopausal women provided 1,091,871 person-years of data included in analyses. Mean predicted one-year breast cancer IRs per 100,000 person-years for each sexual orientation group were: heterosexual 122.55, lesbian 131.61, and bisexual 131.72. IRs were significantly elevated in both lesbian (IRR 1.06; 95 CI 1.06, 1.06) and bisexual (IRR 1.10; 95% CI 1.10, 1.10) women compared to heterosexual women. Conclusions Our findings suggest both lesbian and bisexual women have slightly elevated predicted breast cancer incidence compared to heterosexual women throughout the premenopausal period. Impact Health professionals must ensure that breast cancer prevention efforts are reaching these women. As more health systems around the country collect data on patient sexual orientation, the National Cancer Institute’s SEER cancer registry should add this information to its data system to monitor progress in reducing sexual orientation-related disparities in cancer incidence and mortality.

Significance of Ovarian Function Suppression in Endocrine Therapy for Breast Cancer in Pre-Menopausal Women

PubMed Central

Scharl, A.; Salterberg, A.

2016-01-01

Ovarian function suppression (OFS) for treating breast cancer in pre-menopausal women was introduced for the first time in the late 19th century as bilateral oophorectomy. It was not until the 1960s that the oestrogen receptor was identified and a test for detecting endocrine sensitivity of the breast cancer was developed. A weakness of early trials on OFS for breast cancer treatment is therefore their failure to take receptor sensitivity into account when selecting participants. A meta-analysis performed in the early 1990s first proved that adjuvant OFS significantly improved the cure rate of oestrogen receptor-positive breast cancer in pre-menopausal women regardless of whether it was carried out through oophorectomy, radiation-induced ablation or drug therapy. In the 1970s, tamoxifen was synthesized. It became one of the most important cancer drugs and today constitutes the gold standard for endocrine adjuvant therapy. Taking tamoxifen for a five-year period lowers mortality by 30 % over 15 years. Ten years of tamoxifen therapy reduces mortality even further, with increased side effects, however. Research over the past ten years has proven that for post-menopausal women, aromatase inhibitors have benefits over tamoxifen. Current trial results have rekindled the debate about the combination of OFS with tamoxifen or with aromatase inhibitors for adjuvant breast cancer treatment of pre-menopausal women. These trials have reported an improvement in disease-free survival in patients with a high risk of recurrence when they are treated with a combination of OFS plus tamoxifen or aromatase inhibitors, especially in women younger than 35. However, combination therapy causes significantly more side effects, which could negatively impact compliance. Endocrine treatments administered over a period of many years show waning compliance, which tends to be only around 50 % after five years. Inadequate compliance compromises efficacy and increases the risk of mortality. For

We carried out a case-control study to examine the relationship between fruits, vegetables, and soy foods intake with breast cancer risk in Korean women. Incident cases (n = 359) were identified through cancer biopsies and hospital-based controls (n = 708) were selected in the same hospitals. Subjects were asked to indicate usual dietary habits, which were assessed using a semi-quantitative food frequency questionnaire (98 items). Odds ratio (OR) and 95% confidence intervals (95% CI) were calculated by unconditional logistic regression after adjustment for additional confounding factors according to the menopausal status. High grape intake showed an inverse association of breast cancer in postmenopausal women (OR = 0.59, 95% CI = 0.35-0.95; p for trend = 0.05). High tomato intake was associated with reduced breast cancer risk in premenopausal women (OR = 0.59, 95% CI = 0.38-0.89, p for trend = 0.04). In postmenopausal women, green pepper intake showed an inverse association of breast cancer risk (OR = 0.60, 95% CI = 0.43-0.96, p for trend = 0.03). High soybean intake showed an inverse association of breast cancer in postmenopausal women (OR = 0.61, 95% CI = 0.34-0.89, p for trend = 0.02). Our study suggests that high intake of some fruits, vegetables, and soybeans may be associated with a reduced breast cancer risk.

Reproductive factors are associated with risk of breast cancer, but the association with breast cancer survival is less well known. Previous studies have reported conflicting results on the association between time since last childbirth and breast cancer survival. We determined the association between time since last childbirth (LCB) and survival of women with premenopausal and postmenopausal breast cancers in Malaysia. A historical cohort of 986 premenopausal, and 1123 postmenopausal, parous breast cancer patients diagnosed from 2001 to 2012 in University Malaya Medical Centre were included in the analyses. Time since LCB was categorized into quintiles. Multivariable Cox regression was used to determine whether time since LCB was associated with survival following breast cancer, adjusting for demographic, tumor, and treatment characteristics. Premenopausal breast cancer patients with the most recent childbirth (LCB quintile 1) were younger, more likely to present with unfavorable prognostic profiles and had the lowest 5-year overall survival (OS) (66.9; 95% CI 60.2-73.6%), compared to women with longer duration since LCB (quintile 2 thru 5). In univariable analysis, time since LCB was inversely associated with risk of mortality and the hazard ratio for LCB quintile 2, 3, 4, and 5 versus quintile 1 were 0.53 (95% CI 0.36-0.77), 0.49 (95% CI 0.33-0.75), 0.61 (95% CI 0.43-0.85), and 0.64 (95% CI 0.44-0.93), respectively; P trend  = 0.016. However, this association was attenuated substantially following adjustment for age at diagnosis and other prognostic factors. Similarly, postmenopausal breast cancer patients with the most recent childbirth were also more likely to present with unfavorable disease profiles. Compared to postmenopausal breast cancer patients in LCB quintile 1, patients in quintile 5 had a higher risk of mortality. This association was not significant following multivariable adjustment. Time since LCB is not independently associated with survival in

For premenopausal women with breast cancer, information on the effects of chemotherapy and the risk of infertility is important. In this study, the effect of chemotherapy on the ovarian function in premenopausal women with hormone receptor-positive breast cancer was investigated, with an age-stratified analysis of the appearance of amenorrhea and the resumption of menstruation after the use of chemotherapy with anthracyclines or taxanes. Premenopausal women diagnosed with operable Stage I-III hormone receptor-positive breast cancer and underwent neoadjuvant or adjuvant chemotherapy with the standard regimen of anthracyclines and/or taxanes were included. The patients were classified into age groups in 5-year increments, and the rates of chemotherapy-induced amenorrhea (CIA), resumption of menstruation, and duration of CIA after chemotherapy were analyzed. The subjects consisted of 101 patients (median age 45 years). CIA occurred in 97 (96%) patients and 40 patients resumed menstruation. In all patients aged ≤39 years menstruation restarted, whereas in all patients aged ≥50 years, menstruation did not restart. For the patients who resumed menstruation, the younger the patients, the sooner menstruation tended to restart. The resumption of menstruation occurred within 1 year for younger patients aged around 30 years, but for those aged ≥35 years, 60% of cases took around 2-3 years for resumption. The incidence of CIA, the resumption of menstruation and duration of CIA after chemotherapy depend greatly on the patient's age.

Background: Iron-deficiency anaemia (IDA) is a major worldwide public health problem. Children and women of reproductive age are especially vulnerable to IDA, and it has been reported that these patients are more prone to infection. This study was done to evaluate alteration of lymphocyte subgroups in IDA. Methods: In this prospective study, we investigated lymphocyte subsets in pre-menopausal women with iron-deficiency anaemia; 50 normal subjects and 50 IDA (hypochromic microcytic) cases were enrolled. Experimental and control anticoagulated blood samples were evaluated using flow cytometry to determine the absolute and relative numbers of various lymphocyte subgroups. Finally, the results of the patient and control groups were compared. Results: Mean (SD) absolute counts of lymphocytes, CD3+ cells, CD3+/CD4+ subsets (T helper) and CD3+/CD8+ subsets (T cytotoxic) in the patient group were 2.08 (0.65) x 109/L, 1.53 (0.53) x 109/L, 0.87 (0.28) x 109/L, and 0.51 (0.24) x 109/L, respectively. The results showed significant differences between case and control groups in mean absolute counts of lymphocytes (P = 0.014), T lymphocytes (P = 0.009), helper T cells (P = 0.004), and cytotoxic T cells (P = 0.043). Conclusion: This study showed that absolute counts of peripheral blood T lymphocytes as a marker of cell-mediated immunity may be decreased in pre-menopausal women with iron-deficiency anaemia, and that these patients may be more prone to infection.

Premenopausal women demonstrate a distinctive gynoid body fat distribution and circulating estrogen status is associated with the maintenance of this adiposity patterning. Estrogen's role in modulation of regional adiposity may occur through estrogen receptors (ERs), which are present in human adipose tissue. The purpose of this study was to determine regional differences in the protein content of ERα, ERβ, and the G protein-coupled estrogen receptor (GPER) between the abdominal (AB) and gluteal (GL) subcutaneous adipose tissue of overweight-to-obese premenopausal women. Biopsies of the subcutaneous AB and GL adipose tissue were performed in 15 premenopausal women (7 Caucasian/8 African American, 25.1 ± 1.8 years, BMI 29.5 ± 0.5kg/m(2)). Adipose tissue protein content was measured by western blot analysis and correlation analyses were conducted to assess the relationship between ER protein content and anthropometric indices/body composition measurements. We found that ERα protein was higher in AB than GL (AB 1.0 ± 0.2 vs GL 0.67 ± 0.1 arbitrary units [AU], P=0.02), ERβ protein was higher in GL than AB (AB 0.78 ± 0.12 vs GL 1.3 ± 0.2 AU, P=0.002), ERα/ERβ ratio was higher in AB than GL (AB 1.9 ± 0.4 vs GL 0.58 ± 0.08 AU, P=0.007), and GPER protein content was similar in AB and GL (P=0.80) subcutaneous adipose tissue. Waist-to-hip ratio was inversely related to gluteal ERβ (r(2)=0.315, P=0.03) and positively related to gluteal ERα/ERβ ratio (r(2)=0.406, P=0.01). These results indicate that depot specific ER content may be an important underlying determinant of regional effects of estrogen in upper and lower body adipose tissue of overweight-to-obese premenopausal women.

Yang, Jin Hyang; Yang, Bok Sun

2011-03-01

In this study we explored the perspectives of older Korean women on the principles and meanings of health behavior. Participants were 12 women age 65 and older, with no serious illnesses requiring hospitalization, who were living independently. We used an interpretative phenomenological approach for data collection and analysis. Seven themes emerged: (a) eating well in accordance with one's physical requirements; (b) maintaining one's inherited health; (c) controlling one's illness properly; (d) maintaining good relationships with close relatives and friends; (e) being modest and free from greed; (f) staying in harmony with nature; and (g) regaining energy and vitality. These experiences were mainly based on the traditional Korean concept of health promotion, "food is medicine," rather than on Western concepts of health promotion. In providing optimal geriatric nursing care for Korean older women, the results will be significant because they are based on older women's traditional Korean perspectives of health promotion rather than existing perspectives of Western medicine.

The authors conducted a cross-sectional study to investigate the associations of fat, fiber and carbohydrate intake with endogenous estrogen, androgen, and insulin-like growth factor (IGF) levels among 595 premenopausal women. Overall, no significant associations were found between dietary intake of these macronutrients and plasma sex steroid hormone levels. Dietary fat intake was inversely associated with IGF-I and IGF-binding protein 3 (IGFBP-3) levels. When substituting 5% of energy from total fat for the equivalent amount of energy from carbohydrate or protein intake, the plasma levels of IGF-I and IGFBP-3 were 2.8% (95% confidence interval [CI] 0.3, 5.3) and 1.6% (95% CI 0.4, 2.8) lower, respectively. Animal fat, saturated fat and monounsaturated fat intakes also were inversely associated with IGFBP-3 levels (P < 0.05). Carbohydrates were positively associated with plasma IGF-I level. When substituting 5% of energy from carbohydrates for the equivalent amount of energy from fat or protein intake, the plasma IGF-I level was 2.0% (95% CI 0.1, 3.9%) higher. No independent associations between fiber intake and hormone levels were observed. The results suggest that a low-fat/high-fiber or carbohydrate diet is not associated with endogenous levels of sex steroid hormones, but it may modestly increase IGF-I and IGFBP-3 levels among premenopausal women.

Although Korean American women have one of the highest cervical cancer incidence and mortality rates among all Asian American and non-Hispanic White women, they are less likely to receive the human papillomavirus (HPV) vaccine to prevent cervical cancer. This study aimed to examine Korean American women's HPV literacy and factors related to HPV literacy to identify targeted intervention strategies. A quota sampling strategy was used to recruit 243 Korean American women aged 19-85 years in the Atlanta, Georgia, metropolitan area. Multiple linear regression analysis was conducted using Andersen's Behavioral Model of Health Services Use to examine factors associated with HPV literacy. HPV literacy of Korean American immigrant women was moderate, and knowledge about HPV detection items was particularly low. Age was the only predisposing factor that had a significantly negative association with HPV literacy, whereas education level and English proficiency had a significant positive relationship with HPV literacy. Health status as a need factor was significantly positively associated with HPV literacy.

It is unknown whether intensive lifestyle modification (ILS) or metformin changes sex steroids among premenopausal women without a history of polycystic ovarian syndrome (PCOS). We examined 1-year intervention impact on sex steroids (estradiol, testosterone, dehydroepiandrosterone, and androstenedione [A4]) and SHBG and differences by race/ethnicity. A subgroup of Diabetes Prevention Program participants who were premenopausal, not using estrogen, without a history of PCOS or irregular menses, and who reported non-Hispanic white (NHW), Hispanic, or African-American race/ethnicity (n = 301). Randomization arms were 1) ILS with the goals of weight reduction of 7% of initial weight and 150 minutes per week of moderate intensity exercise, 2) metformin 850 mg twice a day, or 3) placebo. Neither intervention changed sex steroids compared to placebo. ILS, but not metformin, increased median SHBG by 3.1 nmol/L (~11%) compared to decreases of 1.1 nmol/L in the placebo arm (P < .05). This comparison remained significant after adjustment for changes in covariates including waist circumference. However, associations with glucose were not significant. Median baseline A4 was lower in Hispanics compared to NHWs (5.7 nmol/L vs 6.5 nmol/L, P < .05) and increases in A4 were greater in Hispanics compared to NHWs (3.0 nmol/ vs 1.2 nmol/L, P < .05), and these differences did not differ significantly by intervention arm. No other racial/ethnic differences were significant. Among premenopausal glucose-intolerant women, no intervention changed sex steroids. ILS increased SHBG, although associations with glucose were not significant. SHBG and sex steroids were similar by race/ethnicity, with the possible exception of lower baseline A4 levels in Hispanics compared to NHWs.

Breast cancer is a leading cancer diagnosis among premenopausal women around the world. Unlike rates in postmenopausal women, incidence rates of advanced breast cancer have increased in recent decades for premenopausal women. Progress in identifying contributors to breast cancer risk among premenopausal women has been constrained by the limited numbers of premenopausal breast cancer cases in individual studies and resulting low statistical power to subcategorize exposures or to study specific subtypes. The Premenopausal Breast Cancer Collaborative Group was established to facilitate cohort-based analyses of risk factors for premenopausal breast cancer by pooling individual-level data from studies participating in the United States National Cancer Institute Cohort Consortium. This paper describes the Group, including the rationale for its initial aims related to pregnancy, obesity, and physical activity. We also describe the 20 cohort studies with data submitted to the Group by June 2016. The infrastructure developed for this work can be leveraged to support additional investigations. PMID:28600297

To develop successful physical activity promotion programs for midlife immigrant women, especially for Korean immigrant midlife women, concrete theoretical bases are needed. However, virtually no theoretical frameworks and/or theories exist that can explain the influences of immigration transition on the physical activity experience of midlife immigrant women in general or Korean immigrant midlife women in specific. The purpose of this article is to present a situation-specific theory on physical activity experience of Korean immigrant midlife women (SPAKIM) with its development process. An integrative approach was used to develop the theory based on the midlife women's attitudes toward physical activity (MAPA) theory, the transitions theory, a review of the relevant literature, and two studies on midlife women's attitudes toward physical activity. The proposed theory includes nature of transitions, nonmodifiable and modifiable transition conditions, contexts of daily life, patterns of response, and nursing therapeutics as major concepts, and each major concept includes several related subconcepts. Because several concepts of the theory were developed mainly based on the literature review, the major concepts and related subconcepts need to be further developed and evaluated in future studies.

Diethylstilbestrol (DES), a synthetic estrogen widely prescribed to pregnant women in the mid-1900s, is a potent endocrine disruptor. Prenatal DES exposure has been associated with reproductive disorders in women, but little is known about its effects on endogenous hormones. We assessed the association between prenatal DES exposure and reproductive hormones among participants from the Harvard Study of Moods and Cycles (HSMC), a longitudinal study of premenopausal women aged 36-45 years from Massachusetts (1995-1999). Prenatal DES exposure was reported at baseline (43 DES exposed and 782 unexposed). Early follicular-phase concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol were measured at baseline and every 6 months during 36 months of follow-up. Inhibin B concentrations were measured through 18 months. We used multivariable logistic and repeated-measures linear regression to estimate odds ratios (OR) and percent differences in mean hormone values (β), respectively, comparing DES exposed with unexposed women, adjusted for potential confounders. DES-exposed women had lower mean concentrations of estradiol (pg/ml) (β=-15.6%, 95% confidence interval (CI): -26.5%, -3.2%) and inhibin B (pg/ml) (β=-20.3%, CI: -35.1%, -2.3%), and higher mean concentrations of FSH (IU/I) (β=12.2%, CI: -1.5%, 27.9%) and LH (IU/I) (β=10.4%, CI: -7.2%, 31.3%), than unexposed women. ORs for the association of DES with maximum FSH>10 IU/I and minimum inhibin B<45 pg/ml--indicators of low ovarian reserve--were 1.90 (CI: 0.86, 4.22) and 4.00 (CI: 0.88-18.1), respectively. Prenatal DES exposure was associated with variation in concentrations of FSH, estradiol and inhibin B among women of late reproductive age.

We examined the association of serum ferritin levels with metabolic syndrome (MS) and diabetes mellitus in a representative sample of the adult South Korean population using data from the 2008 Korean National Health and Nutrition Examination Survey. We conducted a cross-sectional study of 6311 adults older than 20 years who participated in the 2008 Korean National Health and Nutrition Examination Survey. Metabolic syndrome was defined as the presence of at least 3 of the following: elevated blood pressure, low high-density lipoprotein cholesterol, elevated serum triglycerides, elevated plasma glucose, and abdominal obesity. Diabetes mellitus was defined as fasting glucose of at least 126 mg/dL. Insulin resistance was determined using the homeostasis model assessment estimate of insulin resistance. In a representative sample of the adult Korean population, MS was more prevalent in the highest quartile compared with the lowest quartile of serum ferritin concentrations in women following adjustments for age, education, smoking, alcohol intake, body mass index, aspartate aminotransferase, and alanine aminotransferase. Diabetes mellitus was more prevalent in the highest quartile compared with the lowest quartile of serum ferritin concentrations in premenopausal women and men. The geometric means of fasting insulin and insulin resistance determined using the homeostasis model assessment of insulin resistance in the fourth serum ferritin quartiles of postmenopausal women and men were significantly higher compared with those in the first quartile of the respective groups. The present study demonstrates that elevated serum ferritin concentrations are associated with an increased risk of MS and diabetes mellitus in a representative sample of the adult South Korean population.

This study examined the role of religious affiliations and frequency of religious service attendance-such as church, Bible studies, and temples-as well as religious heterogeneity between couples on intimate partner violence (IPV) among Korean immigrant women in the United States. Through a case-control design, this study compared 64 Korean immigrant IPV victims with 63 Korean immigrant non-IPV victims. This study's findings reveal that for Korean immigrant women, a high frequency of religious service attendance was associated with higher IPV victimization, while their partners' high religious service attendance was associated with lower IPV victimization. When women's partners were religious compared with when they were not religious, they were less likely to perpetrate IPV even when the partners' alcohol consumption frequency increased. Also, when there was a gap between couples regarding frequency of religious attendance, IPV victimization increased. This discussion concludes by suggesting some policy implications based on these findings.

Low BRCA1 gene expression is associated with increased invasiveness and influences the response of breast carcinoma (BC) to chemotherapeutics. However, expression of BRCA1 and BRCA2 genes has not been completely characterized in premenopausal BC. We analyzed the clinical and immunohistochemical correlates of BRCA1 and BRCA2 expression in young BC women. We studied 62 women (mean age 38.8 years) who developed BC before the age of 45 years. BRCA1 and BRCA2 mRNA expression was assessed by reverse transcriptase-polymerase chain reaction (RT-PCR) and that of HER-2 and p53 proteins by immunohistochemistry. Body mass index (BMI) > or = 27 (52%) and a declared family history of BC (26%) were the main risk factors. Ductal infiltrative adenocarcinoma was found in 86% of the cases (tumor size >5 cm in 48%). Disease stages I-IV occurred in 2, 40, 55, and 3%, respectively (73% implicating lymph nodes). Women aged < or = 35 years (24%) had more family history of cervical cancer, stage III/IV disease, HER-2 positivity, and lower BRCA1 expression than older women (P < 0.05). BRCA1 and BRCA2 expression correlated in healthy, but not in tumor tissues (TT). Neither BRCA1 nor BRCA2 expression was associated with tumor histology, differentiation, nodal metastasis or p53 and HER-2 expression. After multivariate analysis, only disease stage explained BRCA1 mRNA levels in the lowest quartile. Premenopausal BC has aggressive clinical and molecular characteristics. Low BRCA1 mRNA expression is associated mainly with younger ages and advanced clinical stage of premenopausal BC. BRCA2 expression is not associated with disease severity in young BC women.

Domestic violence against married women has persisted throughout Korean history. However, very little empirical research has been conducted in Korea about domestic violence, its causes, or women's responses. To develop and test psychometrically the Korean Women's Abuse Intolerance Scale (KWAIS) to measure women's propensity or desire to leave abusive husbands in Korea. The first phase of the investigation involved qualitative research to explore the themes of women's responses to domestic violence and the development of the instrument. The second phase was a preliminary study conducted to examine women's responses to domestic violence. In the third phase, construct validity of the scale was established, using a sample of 184 married women living in Korea. The KWAIS adequately supported the underlying theory of women's responses to domestic violence, demonstrating strong content validity, high internal consistency (Cronbach's alpha of .98), and criterion-related validity evidenced by significant correlations that supported hypotheses among abuse intolerance and abuse (r = .69), traditional family ideology (r = -.78), marital satisfaction (r = -.85), attitude toward power ascription (r = .63), and collectivism (r = -.88). Factor analysis yielded a four-factor structure, explaining 78.4% of the common variance. Factor loadings ranged from .65 to .93. The findings for the psychometric properties of the KWAIS established its potential as a research instrument in measuring Korean women's propensity or desire to leave abusive husbands. Future studies need to focus on determining the predictive validity of the KWAIS and evaluating cross-cultural differences in women's propensity or desire to leave abusive husbands.

Substances identified as animal carcinogens are no longer used as ingredients of hair dyes. However, hair dyes are diverse groups of chemicals, and certain compounds may affect endogenous sex hormone levels. We examined the association between hair dye use and sex hormone levels among premenopausal women. Study subjects were 431 premenopausal Japanese women who had regular menstrual cycles less than 40 days long. Information on the use of hair dyes or hair bleach, the type of hair coloring used, the duration of use and the frequency of application was collected using a self-administered questionnaire. Fasting plasma samples were obtained to measure estradiol, testosterone, dehydroepiandrosterone sulfate, sex hormone-binding globulin, follicle-stimulating hormone and luteinizing hormone. After controlling for covariates, the mean plasma total testosterone level was about 14% higher in women who had used hair dyes for 10 or more years than that among women who had never used them (P for trend = 0.02). A similar association was observed when the type of hair dye was restricted to permanent hair dyes. A higher frequency of applying non-permanent hair dyes was marginally significantly associated with higher total and free estradiol levels. Data suggest that long-term use of hair dyes may be associated with an increase in circulating testosterone levels. As this is, to our knowledge, the first study examining the association between hair dye use and sex hormone levels, replication of the results is required. © The Author 2015.

Although hypoactive sexual desire disorder (HSDD) is the most common sexual complaint, there is no consensus for the ideal treatment. Our study aimed to evaluate the efficacy of treating premenopausal women with HSDD with Tribulus terrestris and its effect on the serum levels of testosterone. We performed a prospective, randomized, double-blind, placebo-controlled trial, with 40 premenopausal women reporting diminished libido, receiving T. terrestris or placebo. The questionnaires FSFI and the QS-F were used to evaluate sexual dysfunction before and after treatment. Patients treated with T. terrestris experienced improvement in total score of FSFI (p < .001) and domains "desire" (p < .001), "sexual arousal" (p = .005), "lubrication" (p = .001), "orgasm" (p <.001), "pain" (p = .030) and "satisfaction" (p = .001). Treatment with placebo did not improve the scores for the "lubrication" and "pain". QS-F scores showed that patients using T. terrestris had improvements in "desire" (p = .012), "sexual arousal/lubrication" (p = .002), "pain" (p = .031), "orgasm" (p = .004) and "satisfaction" (p = .001). Women treated with placebo did not score improvements. Women receiving T. terrestris had increased levels of free (p = .046) and bioavailable (p < .048) testosterone. T. terrestris might be a safe alternative for the treatment of premenopausal women with HSDD as it was effective in reducing the symptoms, probably due to an increase in the serum levels of free and bioavailable testosterone.

This study aimed to assess the effects of hysterectomy and bilateral salpingo-oophorectomy (BSO)--compared with the effects of hysterectomy alone--on skin aging in premenopausal women undergoing hysterectomy for benign conditions. One hundred thirty-five premenopausal women who underwent hysterectomy with BSO were compared with a control group of women who underwent hysterectomy alone based on skin parameters (including wrinkling, laxity/sagging, and texture/dryness) and Skindex-29 questionnaire scores. The inclusion criteria were as follows: aged between 40 and 50 years, follicle-stimulating hormone level lower than 40 mIU/mL, undergoing hysterectomy with or without BSO for benign conditions, and not receiving estrogen or progesterone treatment. The exclusion criteria were as follows: adrenocortical hyperplasia or Cushing's syndrome; use of corticosteroids for autoimmune diseases; malignancy, connective tissue diseases (eg, Ehlers-Danlos syndrome), or dermatological diseases (eg, lichen sclerosus); or regular use of medications known to interfere with the condition of the skin. All skin parameters in the hysterectomy group and the hysterectomy with BSO group worsened on weeks 24 and 48. Laxity/sagging and texture/dryness scores on weeks 24 and 48 were significantly worse in the BSO group; laxity/sagging and texture/dryness scores continued to worsen between 24 and 48 weeks. Scores for the Skindex-29 questionnaire emotion and symptom subscales were significantly higher in the BSO group compared with the non-BSO group. Prophylactic BSO during hysterectomy is a significant independent risk factor for worsening skin laxity/sagging and texture/dryness in premenopausal women undergoing hysterectomy for benign conditions. Prophylactic BSO in the presence of dermatological conditions is also associated with reduced quality of life.

This paper is a report of a descriptive study of young Korean women's perceptions of use of the human papilloma virus vaccine. In Korea, cervical cancer is one of the leading cancers in women, and the rate of human papilloma virus infection is increasing. A national media campaign has recently begun to promote human papilloma virus vaccination. However, research addressing the acceptability of this vaccine to women in Korea has been limited. Twenty-five Korean women, 21-30 years of age, participated in seven focus groups. The data were collected in 2007. Participants were concerned about the potential harmful effects of the human papilloma virus vaccine, a possible increase in unsafe sexual behaviours, and the high cost of the vaccine, which is not covered by health insurance. They suggested group vaccination at-cost or free of charge. They discussed ambivalence about the vaccination, the need for more information about the vaccine, and questions about its effectiveness. Most preferred to wait until more people have been vaccinated. There is a need for more aggressive dissemination of information about the safety and efficacy of the human papilloma virus vaccine. More reasonable cost, insurance coverage, or free vaccination using a group approach might increase young Korean women's acceptance and use of the human papilloma virus vaccine.

Korean immigrants rely heavily on their respective churches for assistance with domestic violence. Yet, Korean clergy's responses to domestic violence are unknown. The purpose of this study was to examine factors that influence Korean clergy's responses to domestic violence in their congregations. Results showed that clergy's Korean cultural values, age, and length of residence in the United States influence their responses to domestic violence. Developing a collaborative working relationship between Korean clergy and domestic violence advocates, as well as providing training to Korean clergy targeting their knowledge, beliefs/attitudes, and skills is critical for promoting safety of battered Korean immigrant women. © The Author(s) 2015.

We investigated whether serum from normal weight women is less mitogenic and more apoptotic than sera from the same women in the overweight state. Sera from premenopausal women, age (mean ±SEE) 34.6±0.53 years, who were randomized to caloric restriction (CR) (n=13), CR + aerobic exercise (AE) (n=14) or CR + resistance training (RT) (n=20) were used to culture endometrial cancer cells. Phases of the cell cycle were determined, proliferating cell nuclear antigen (PCNA) positivity was used to assess proliferation and apoptosis was assessed by determining cleaved caspase-3 and poly-ADP-ribose polymerase (PARP). Analyses showed that overall, cells grown in sera from the weight-reduced state had significantly more cells in G0/G1 and significantly fewer cells in the S and G2/M phases of the cell cycle than cells grown in sera from the overweight state. PCNA staining confirmed that cells grown in sera from the weight-reduced state had fewer proliferating cells. Cleaved caspase-3 and PARP were not different in cells grown in sera from the weight-reduced state compared to the overweight state. We conclude that weight loss with or without exercise could lower the risk for cancer through changes in serum that result in reduced cellular mitogenicity. PMID:21774593

A systematic review is done to determine the efficacy and safety of levonorgestrel-releasing intrauterine systems as a treatment using in premenopausal women with symptomatic uterine leiomyoma. We searched the Medline, Central and ICTRP databases for all articles published from inception through July 2013 that examined the following outcomes: uterine volume, uterine leiomyoma volume, endometrial thickness, then menstrual blood loss, blood haemoglobin, ferritin and hematocrit levels, treatment failure rate, device expulsion rate, hysterectomy rate and side effects. From 645 studies, a total of 11 studies met our inclusion criteria with sample sizes ranging from 10 to 104. Evidence suggested that levonorgestrel-releasing intrauterine systems could decrease uterine volume and endometrial thickness, significantly reduce menstrual blood loss, and increase blood haemoglobin, ferritin and hematocrit levels. There was no evidence for decreasing uterine leiomyoma volume. There were no adverse effects on the ovarian function except for ovarian cysts. Device expulsion rates were low, which associated with leiomyoma size (larger than 3cm) but not with leiomyoma location. Irregular bleeding/spotting was observed at the beginning of the follow-up period and then decreased progressively. Results of this systematic review indicate that levonorgestrel-releasing intrauterine systems may be effective and safe treatment for symptomatic uterine leiomyoma in premenopausal women.

To examine the impact on quality of life of recurrent acute uncomplicated urinary tract infection among premenopausal Singaporean women, and to determine the risk factors for lower quality of life among these patients. A total of 85 patients with recurrent acute uncomplicated urinary tract infection who were referred to the Urology Department at the National University Hospital, Singapore, were prospectively recruited over a 3-year period to complete the validated Short Form 36 Health Survey version 1. In addition, demographic and clinical details including symptomology and medical history were analyzed for factors impacting quality of life. Short Form 36 Health Survey version 1 results were compared with published population norms. After adjusting for age, gender and race, recurrent acute uncomplicated urinary tract infection patients had significantly lower quality of life on seven out of eight Short Form 36 Health Survey version 1 domains when compared with age-, gender- and race-adjusted population norms for Singapore. Among those with recurrent acute uncomplicated urinary tract infection, those who also reported caffeine consumption had significantly lower Short Form 36 Health Survey version 1 scores than those who did not. Those who reported chronic constipation also had consistently lower Short Form 36 Health Survey version 1 scores across all domains. Recurrent acute uncomplicated urinary tract infection has a negative impact on the quality of life of premenopausal, otherwise healthy women. Recurrent acute uncomplicated urinary tract infection patients who also have chronic constipation or consume caffeine have lower quality of life than those who do not. More studies are required to understand the relationships between these common problems and risk factors. © 2018 The Japanese Urological Association.

Purpose Risedronate prevents bone loss in postmenopausal women. The purpose of this study was to determine whether risedronate prevents bone loss in premenopausal women undergoing chemotherapy for breast cancer. Patients and Methods Premenopausal women undergoing chemotherapy for breast cancer were treated with oral calcium 600 mg and vitamin D 400 U daily and randomly assigned to receive oral risedronate 35 mg weekly or placebo, with all these therapies beginning within a month of the start of chemotherapy. Most chemotherapy regimens included anthracyclines, taxanes, or cyclophosphamide. Bone mineral density (BMD) was measured at baseline and 1 year. The primary end point was the change in lumbar spine (LS) BMD from baseline to 1 year. Results A total of 216 women enrolled; 170 women provided BMD data at 1 year. There was no difference in the mean change or percent change in LS BMD between groups, with a loss of 4.3% in the risedronate arm and 5.4% for placebo at 1 year (P = .18). Loss of BMD at the femoral neck and total hip were also similar between treatment groups. Risedronate was well tolerated, with no significant differences in adverse events compared with placebo, except that arthralgias and chest pain were worse in those receiving the placebos. Conclusion Risedronate did not prevent bone loss in premenopausal women undergoing adjuvant chemotherapy for breast cancer. PMID:19075260

Background Cadmium, a persistent and widespread environmental pollutant, has been associated with kidney function impairment and several diseases. Cigarettes are the dominant source of cadmium exposure among smokers; the primary source of cadmium in non-smokers is food. We investigated sources of cadmium exposure in a sample of healthy women. Methods In a cross-sectional study, 191 premenopausal women completed a health questionnaire and a food frequency questionnaire. The cadmium content of spot urine samples was measured with inductively-coupled plasma mass spectrometry and normalized to urine creatinine content. Multivariable linear regression was used to estimate the strength of association between smoking habits and, among non-smokers, usual foods consumed and urinary cadmium, adjusted for age, race, multivitamin and supplement use, education, estimated total energy intake, and parity. Results Geometric mean urine creatinine-normalized cadmium concentration (uCd) of women with any history of cigarette smoking was 0.43 μg/g (95% confidence interval (CI): 0.38–0.48 μg/g) and 0.30 μg/g (0.27–0.33 μg/g) among never-smokers, and increased with pack-years of smoking. Analysis of dietary data among women with no reported history of smoking suggested that regular consumption of eggs, hot cereals, organ meats, tofu, vegetable soups, leafy greens, green salad, and yams was associated with uCd. Consumption of tofu products showed the most robust association with uCd; each weekly serving of tofu was associated with a 22% (95% CI: 11–33%) increase in uCd. Thus, uCd was estimated to be 0.11 μg/g (95% CI: 0.06 – 0.15 μg/g ) higher among women who consumed any tofu than among those who consumed none. Conclusions Cigarette smoking is likely the most important source of cadmium exposure among smokers. Among non-smokers, consumption of specific foods, notably tofu, is associated with increased urine cadmium concentration. PMID:21333327

Background Evidence for an association between vitamin D status and breast cancer is now more convincing, but is uncertain in subtropical areas like Taiwan. This hospital-based case-control study examined the relationship of breast cancer with vitamin D intake and sunlight exposure. Methods A total of 200 incident breast cancer cases in a Taipei hospital were matched with 200 controls by date of interview and menopausal status. Information on risk factors for breast cancer was collected in face-to-face interviews and assessed with reference to vitamin D intake (foods and nutrients) and sunlight exposure. Vitamin D intake was divided into quartiles, and threshold effect was evaluated by comparing Q2–Q4 with Q1. Results After controlling for age, education, parity, hormone replacement therapy, body mass index (BMI), energy intake, menopausal status, and daily sunlight exposure, the risk of breast cancer in participants with a dietary vitamin D intake greater than 5 µg per day was significantly lower (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.24–0.97) than that of participants with an intake less than 2 µg per day. In analysis stratified by menopausal status and BMI, both dietary vitamin D and total vitamin D intakes were associated with a protective effect among premenopausal women. There was a significant linear trend for breast cancer risk and dietary vitamin D intake in premenopausal women (P = 0.02). In participants with a BMI lower than 24 kg/m2 (ie, normal weight), dietary vitamin D intake was inversely related to breast cancer risk (P for trend = 0.002), and a threshold effect was apparent (Q2–Q4 vs Q1: OR, 0.46; 95% CI, 0.23–0.90). Conclusions Vitamin D had a protective effect against breast cancer in premenopausal women of normal weight in subtropical Taiwan, especially an intake greater than 5 µg per day. PMID:21160130

Previous genome-wide association studies (GWAS) have identified common variants in genes associated with variation in bone mineral density (BMD), although most have been carried out in combined samples of older women and men. Meta-analyses of these results have identified numerous SNPs of modest effect at genome-wide significance levels in genes involved in both bone formation and resorption, as well as other pathways. We performed a meta-analysis restricted to premenopausal white women from four cohorts (n= 4,061 women, ages 20 to 45) to identify genes influencing peak bone mass at the lumbar spine and femoral neck. Following imputation, age- and weight-adjusted BMD values were tested for association with each SNP. Association of a SNP in the WNT16 gene (rs3801387; p=1.7 × 10−9) and multiple SNPs in the ESR1/C6orf97 (rs4870044; p=1.3 × 10−8) achieved genome-wide significance levels for lumbar spine BMD. These SNPs, along with others demonstrating suggestive evidence of association, were then tested for association in seven Replication cohorts that included premenopausal women of European, Hispanic-American, and African-American descent (combined n=5,597 for femoral neck; 4,744 for lumbar spine). When the data from the Discovery and Replication cohorts were analyzed jointly, the evidence was more significant (WNT16 joint p=1.3 × 10−11; ESR1/C6orf97 joint p= 1.4 × 10−10). Multiple independent association signals were observed with spine BMD at the ESR1 region after conditioning on the primary signal. Analyses of femoral neck BMD also supported association with SNPs in WNT16 and ESR1/C6orf97 (p< 1 × 10−5). Our results confirm that several of the genes contributing to BMD variation across a broad age range in both sexes have effects of similar magnitude on BMD of the spine in premenopausal women. These data support the hypothesis that variants in these genes of known skeletal function also affect BMD during the premenopausal period. PMID:23074152

Previous genome-wide association studies (GWAS) have identified common variants in genes associated with variation in bone mineral density (BMD), although most have been carried out in combined samples of older women and men. Meta-analyses of these results have identified numerous single-nucleotide polymorphisms (SNPs) of modest effect at genome-wide significance levels in genes involved in both bone formation and resorption, as well as other pathways. We performed a meta-analysis restricted to premenopausal white women from four cohorts (n = 4061 women, aged 20 to 45 years) to identify genes influencing peak bone mass at the lumbar spine and femoral neck. After imputation, age- and weight-adjusted bone-mineral density (BMD) values were tested for association with each SNP. Association of an SNP in the WNT16 gene (rs3801387; p = 1.7 × 10(-9) ) and multiple SNPs in the ESR1/C6orf97 region (rs4870044; p = 1.3 × 10(-8) ) achieved genome-wide significance levels for lumbar spine BMD. These SNPs, along with others demonstrating suggestive evidence of association, were then tested for association in seven replication cohorts that included premenopausal women of European, Hispanic-American, and African-American descent (combined n = 5597 for femoral neck; n = 4744 for lumbar spine). When the data from the discovery and replication cohorts were analyzed jointly, the evidence was more significant (WNT16 joint p = 1.3 × 10(-11) ; ESR1/C6orf97 joint p = 1.4 × 10(-10) ). Multiple independent association signals were observed with spine BMD at the ESR1 region after conditioning on the primary signal. Analyses of femoral neck BMD also supported association with SNPs in WNT16 and ESR1/C6orf97 (p < 1 × 10(-5) ). Our results confirm that several of the genes contributing to BMD variation across a broad age range in both sexes have effects of similar magnitude on BMD of the spine in premenopausal women. These data support the

The stranded individualizer under compressed modernity: South Korean women in individualization without individualism.

South Korean families have functioned as a highly effective receptacle for the country's highly compressed conditions of modernity and late modernity. It is as much due to the success of South Korean families as an engine of compressed modernity as due to their failure that they have become functionally overloaded and socially risk-ridden. Such familial burdens and risks are particularly onerous to South Korean women because of the fundamentally gender-based structure of family relations and duties that has in part been recycled from the Confucian past and in part manufactured under industrial capitalism. Under these complicated conditions, South Korean women have had to dramatically restructure their family relations and duties as well as their individual life choices. Furthermore, under the most recent condition of what Beck calls second modernity, other institutions of modernity, such as the state, industrial economy, firms, unions, schools, and welfare systems, have become increasingly ineffective in helping to alleviate such (gender-based) familial burdens and dilemmas. As a result South Korean women have experienced dramatic changes in marriage patterns, fertility, family relations, etc. South Korean women's individualization has thereby taken place primarily as a matter of practicality rather than ideational change. A brief analysis of the situation in the neighbouring societies of Japan and Taiwan reinforces the conclusion that individualization without individualism, particularly among women, is a region-wide phenomenon in East Asia. © London School of Economics and Political Science 2010.

Most studies about multiple roles and women's health suggested that combining with paid job, being married and having children was more likely to improve health status than in case of single or traditional roles. We investigated whether there was better health outcome in multiple roles among Korean women coinciding with previous studies of other nations. Data were from the 2005 Korea National Health & Nutritional Examination Survey, a subsample of women aged 25-59 years (N=2,943). Health status was assessed for self-rated poor health, perceived stress and depression, respectively based on one questionnaire item. The age-standardized prevalence of all health outcomes were calculated by role categories and socioeconomic status. Multiple logistic regression was used to assess the association of self rated health, perceived stress, and depression with multiple roles adjusted for age, education, household income, number of children and age of children. Having multiple roles with working role was not associated with better health and psychological wellbeing. Compared to those with traditional roles, employed women more frequently experienced perceived stress, with marital and/or parental roles. Non-working single mothers suffered depression more often than women with traditional roles or other role occupancy. Socioeconomic status indicators were potent independent correlates of self-rated health and perceived stress. Employment of women with other roles did not confer additional health benefit to traditional family responsibility. Juggling of work and family responsibility appeared more stressful than traditional unemployed parental and marital role in Korean women.

Park, K J; Peterson, L M

1991-01-01

Korean women's health beliefs and childbirth experiences in the United States were examined. A convenience sampling procedure was used, and face-to-face interviews were conducted in Korean. Interviews were audiotaped, typed, and translated from Korean to English. These women had a holistic concept of health. Some practices were influence by ancient Chinese medicine. Childbirth experiences indicated that language is a barrier requiring specific interventions. Recommendations include (a) development of an assessment tool with which health-care professionals can identify individual health beliefs early in pregnancy; (b) development of a bilingual pamphlet about medical terms and the U.S. health-care system; (c) development of a short bilingual dictionary of common foods for use in menu selection during hospitalization; and (d) provision of English practice periods based on anticipatory guidance principles to prepare women to ask for specific assistance.

Sex hormone concentrations differ between men, premenopausal women with natural menstrual cycles (NAT), and premenopausal women using oral contraceptive pills (OCP), as well as across menstrual or OCP phases. This study sought to investigate how differences in sex hormones, particularly estradiol, between men and women and across cycle phases, may influence brachial artery endothelial function. Fifty-three healthy adults (22{plus minus}3 yrs; 20 men, 15 NAT, 18 second, third or fourth generation OCP) underwent assessments of sex hormones and endothelial (flow-mediated dilation test, FMD) and smooth muscle (nitroglycerin test, NTG) function. Men were tested three times at one-week intervals, and women were tested three times throughout a single menstrual or OCP cycle (NAT: menstrual, mid-follicular, luteal; OCP: placebo/no pill, 'early' and 'late' active pill). Endogenous estradiol concentration was comparable between men and women in their NAT menstrual or OCP placebo phase (p=0.36) but increased throughout a NAT cycle (p<0.001). Allometrically scaled FMD did not change across a NAT or OCP cycle but was lower in both groups of women than men (p=0.005), whereas scaled NTG was lower only in NAT women (p=0.001). Changes in estradiol across a NAT cycle were not associated with changes in relative FMD (r2=0.01, p=0.62) or NTG (r2=0.09, p=0.13). Duration of OCP use was negatively associated with the average relative FMD for second generation OCP users only (r=-0.65, p=0.04). Our findings suggest that brachial endothelial function is unaffected by cyclic hormonal changes in premenopausal women but may be negatively impacted by longer term use of second generation OCPs.

Chemokine CX3CL1 (fractalkine) may be an important factor linking thyroid status and bone remodeling, through tetrac, a derivative of thyroxine. This study explores the relationship between serum fractalkine levels and parameters of thyroid status and bone in premenopausal women with Graves' disease (GD) in comparison to healthy controls. This cross-sectional study included three premenopausal female groups: active GD; cured GD, and healthy age-, gender-, and BMI-matched controls. Measurement of serum fractalkine levels (Quantikine ® ELISA), total amino-terminal peptide of procollagen type 1 (P1NP), CTx, thyroid hormones, BMD and trabecular bone score (TBS) were performed in all study subjects. Sixty women (21, 16, and 23 in active GD, cured GD, and healthy control groups, respectively) were included. Serum fractalkine levels were higher (p<0.05) in active and cured GD subjects compared to healthy controls (mean 0.7±0.14; 0.93±0.15, and 0.48±0.13 ng/ml, respectively). Lumbar spine BMD was lowest in the cured GD group in comparison to active GD and control group subjects (0.926±0.03; 1.016±0.03; 1.051±0.03 g/cm 2 ; p<0.05, respectively). TBS was lower (p<0.05) in both GD groups than controls being lowest in those with active GD (1.395±0.02; 1.402±0.02, 1.469±0.02, respectively). Serum fractalkine concentration was positively correlated with fT4, and negatively correlated with TBS values. GD in pre-menopausal females is associated with increased serum fractalkine concentration and decreased TBS. Fractalkine may be a currently unappreciated link between hyperthyroidism and bone; further research into this possibility is needed. © Georg Thieme Verlag KG Stuttgart · New York.

Higher levels of oxidative stress, as measured by F2-isoprostanes, have been associated with chronic diseases such as CVD and some cancers. Improvements in diet and physical activity may help reduce oxidative stress; however, previous studies regarding associations between lifestyle factors and F2-isoprostane concentrations have been inconsistent. The aim of this cross-sectional study was to investigate whether physical activity and intakes of fruits/vegetables, antioxidant nutrients, dietary fat subgroups and alcohol are associated with concentrations of F2-isoprostane and the major F2-isoprostane metabolite. Urinary F2-isoprostane and its metabolite were measured in urine samples collected at enrolment from 912 premenopausal women (aged 35-54 years) participating in the Sister Study. Physical activity, alcohol consumption and dietary intakes were self-reported via questionnaires. With adjustment for potential confounders, the geometric means of F2-isoprostane and its metabolite were calculated according to quartiles of dietary intakes, alcohol consumption and physical activity, and linear regression models were used to evaluate trends. Significant inverse associations were found between F2-isoprostane and/or its metabolite and physical activity, vegetables, fruits, vitamin C, α-carotene, vitamin E, β-carotene, vitamin A, Se, lutein+zeaxanthin and long-chain n-3 fatty acids. Although trans fats were positively associated with both F2-isoprostane and its metabolite, other dietary fat subgroups including SFA, n-6 fatty acids, n-3 fatty acids, MUFA, PUFA, short-chain n-3 fatty acids, long-chain n-3 fatty acids and total fat were not associated with either F2-isoprostane or its metabolite. Our findings suggest that lower intake of antioxidant nutrients and higher intake of trans fats may be associated with greater oxidative stress among premenopausal women.

This qualitative study was designed to examine the benefits of leisure to older Korean women. Using a constructive grounded theory methodology, in this study we identified three categories of benefits from leisure activities: (a) developing social connections, (b) enhancing psychological well-being, and (c) improving physical health. The findings of this study demonstrate that involvement in leisure activities offers substantial physical, psychological, and social benefits for older Korean women. The results also suggest that these benefits can provide an opportunity for older Korean adults to improve their health and well-being, which, in turn, may help promote successful aging.

Estrogen suppression in premenopausal women following 8 weeks of treatment with exemestane and triptorelin versus triptorelin alone.

2009-02-01

Luteinizing hormone-releasing hormone (LHRH) agonists (e.g., triptorelin) reduce ovarian estrogen production in premenopausal women with hormone-sensitive breast cancer. Aromatase inhibitors (e.g., exemestane) inhibit extraovarian production of estrogen and may further reduce circulating estrogens when combined with an LHRH agonist. Healthy premenopausal women were randomized to receive 3.75 mg triptorelin (T) on days 1 and 29 with 25 mg exemestane (EX) or matched placebo once daily for 8 weeks, from day 1 to day 56. The primary objective was to evaluate the effect of T +/- EX on estradiol (E(2)) suppression by comparing the AUC(day 36-57 )for the 2 treatments. Secondary objectives included evaluation of estrone (E(1)), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) suppression; effects of EX on the T-induced gonadotrophin and estrogen flare; pharmacokinetics (PK); and safety. Twenty-eight (14 in each arm) were evaluable for efficacy and PK. Mean plasma estrogen levels (AUC(day 36-57)) were significantly lower for subjects who received T + EX than for subjects who received T alone (20.6 vs. 54.0 pg d/ml [-62%; P < 0.05], and 38.9 vs. 198.0 pg d/ml [-80%; P < 0.01] for E(2) and E(1), respectively). Coadministration of EX did not affect the initial flare or subsequent suppression of LH and FSH following the first dose of T, or the PK of T. Both treatments were well tolerated. Coadministration of T and EX resulted in greater estrogen suppression than when T was given alone. These findings could translate into improved clinical outcomes for premenopausal breast cancer patients receiving LHRH agonists.

This study tested key tenets of objectification theory with South Korean women and explored the roles of sexually objectifying media and culture-specific standards of beauty in body image and eating disorder symptoms. Two pilot studies with South Korean college women (n = 40, n = 30) revealed that facial characteristics such as size and shape represent a discrete variable among culture-specific standards of beauty for South Korean women. Results with a sample of 562 South Korean college women indicated that media exposure had significant positive indirect relations with body shame and eating disorder symptoms through the mediating roles of internalization, body surveillance, and face surveillance. Internalization of cultural standards of beauty had significant positive direct relations with body surveillance and face surveillance and had both direct and indirect relations with body shame and eating disorder symptoms. Body and face surveillances had significant positive direct relations with body shame and had indirect relations with eating disorder symptoms. Finally, body shame mediated the links from internalization and surveillance variables to eating disorder symptoms. The results support the applicability of objectification theory as it relates to South Korean women and point to the significance of culture-specific standards of beauty within that framework. These findings could contribute to the broader field of multicultural body image research, with potential implications for therapist practices and training.

Purpose Adolescence is hypothesized to be a time period of particular susceptibility to breast cancer risk factors. Red meat and fat intake during high school was positively associated with risk of breast cancer among premenopausal women in the Nurses’ Health Study II (NHSII). High mammographic density is a strong predictor of breast cancer risk but there is limited research on dietary factors associated with breast density. To test the hypothesis that high intake of animal fat or red meat during adolescence is associated with mammographic density, we analyzed data from premenopausal women in the NHSII. Methods Participants recalled adolescent diet on a high school food frequency questionnaire. We assessed absolute and percent mammographic density on digitized analog film mammograms for 687 premenopausal women with no history of cancer. We used generalized linear regression to quantify associations of adolescent animal fat and red meat intake with mammographic density, adjusting for age, body mass index, and other predictors of mammographic density. Results Adolescent animal fat intake was significantly positively associated with premenopausal mammographic density, with a mean percent density of 39.2% in the lowest quartile of adolescent animal fat intake vs. 43.1% in the highest quartile (p-trend: 0.03). A non-significant positive association was also observed for adolescent red meat intake (p-trend: 0.14). Conclusions These findings suggest that higher adolescent animal fat intake is weakly associated with percent mammographic density in premenopausal women. PMID:26791521

Menopause is a natural phenomenon of aging, although the timing and management of menopause can significantly affect a woman's quality of life. It is therefore important to identify measures to ensure a healthy menopause. We set out to investigate the association between hypertension and early menopause in Korean women. This cross-sectional study was based on 2008-2013 data from the Korea National Health and Nutrition Examination Survey (KNHANES). Of the 53,829 participants surveyed, 13,584 women were selected. We analyzed the contents of the health interview, health examination, and nutrition survey. The main outcome was defined based on hazard ratios (HR) to identify the effects of hypertension on age at onset of menopause. Among postmenopausal women (n=6650), the mean age at onset of menopause was 50.4 years. Premenopausal hypertension was statistically significantly associated with age at menopause, oral contraceptive usage, household income, education level, occupation, marital status and smoking and drinking habits. With lower age at diagnosis of hypertension, HRs for menopause tended to be higher, and hypertension diagnosed before age 40 years conferred a statistically significantly higher HR (Model 1, HR=2.32, 95% CI=1.87-2.88; Model 2, HR=2.31, 95% CI=1.86-2.86; Model 3, HR=2.23, 95% CI=1.80-2.77; Model 4, HR=2.00, 95% CI=1.52-2.63). Premature menopause is strongly associated with lifestyle factors, in combination with incomplete management of chronic diseases. Our findings support the hypothesis that younger age at diagnosis of hypertension is associated with younger age at onset of menopause in Korean women. Copyright © 2016 Elsevier Ireland Ltd.

Suppression of ovarian estrogen production reduces the recurrence of hormone-receptor-positive early breast cancer in premenopausal women, but its value when added to tamoxifen is uncertain. We randomly assigned 3066 premenopausal women, stratified according to prior receipt or nonreceipt of chemotherapy, to receive 5 years of tamoxifen, tamoxifen plus ovarian suppression, or exemestane plus ovarian suppression. The primary analysis tested the hypothesis that tamoxifen plus ovarian suppression would improve disease-free survival, as compared with tamoxifen alone. In the primary analysis, 46.7% of the patients had not received chemotherapy previously, and 53.3% had received chemotherapy and remained premenopausal. After a median follow-up of 67 months, the estimated disease-free survival rate at 5 years was 86.6% in the tamoxifen-ovarian suppression group and 84.7% in the tamoxifen group (hazard ratio for disease recurrence, second invasive cancer, or death, 0.83; 95% confidence interval [CI], 0.66 to 1.04; P=0.10). Multivariable allowance for prognostic factors suggested a greater treatment effect with tamoxifen plus ovarian suppression than with tamoxifen alone (hazard ratio, 0.78; 95% CI, 0.62 to 0.98). Most recurrences occurred in patients who had received prior chemotherapy, among whom the rate of freedom from breast cancer at 5 years was 82.5% in the tamoxifen-ovarian suppression group and 78.0% in the tamoxifen group (hazard ratio for recurrence, 0.78; 95% CI, 0.60 to 1.02). At 5 years, the rate of freedom from breast cancer was 85.7% in the exemestane-ovarian suppression group (hazard ratio for recurrence vs. tamoxifen, 0.65; 95% CI, 0.49 to 0.87). Adding ovarian suppression to tamoxifen did not provide a significant benefit in the overall study population. However, for women who were at sufficient risk for recurrence to warrant adjuvant chemotherapy and who remained premenopausal, the addition of ovarian suppression improved disease outcomes. Further

Abstract Background An increased risk of breast cancer is associated with alcohol consumption; however, it is controversial whether red wine increases this risk. Aromatase inhibitors (AIs) prevent the conversion of androgens to estrogen and occur naturally in grapes, grape juice, and red, but not white wine. We tested whether red wine is a nutritional AI in premenopausal women. Methods In a cross-over design, 36 women (mean age [SD], 36 [8] years) were assigned to 8 ounces (237 mL) of red wine daily then white wine for 1 month each, or the reverse. Blood was collected twice during the menstrual cycle for measurement of estradiol (E2), estrone (E1), androstenedione (A), total and free testosterone (T), sex hormone binding globulin (SHBG), luteinizing hormone (LH), and follicle stimulating hormone (FSH). Results Red wine demonstrated higher free T vs. white wine (mean difference 0.64 pg/mL [0.2 SE], p=0.009) and lower SHBG (mean difference −5.0 nmol/L [1.9 SE], p=0.007). E2 levels were lower in red vs. white wine but not statistically significant. LH was significantly higher in red vs. white wine (mean difference 2.3 mIU/mL [1.3 SE], p=0.027); however, FSH was not. Conclusion Red wine is associated with significantly higher free T and lower SHBG levels, as well as a significant higher LH level vs. white wine in healthy premenopausal women. These data suggest that red wine is a nutritional AI and may explain the observation that red wine does not appear to increase breast cancer risk. PMID:22150098

This observational case series in 65 premenopausal women with abnormal uterine bleeding evaluated whether transvaginal ultrasound followed by saline infusion sonohysterography (SIS) prevented unnecessary hysteroscopy. Although SIS indicated that hysteroscopy was unnecessary in eight women, this benefit was offset by the invasive nature of the scan, the number of endometrial abnormalities falsely detected by SIS and the cost of the additional investigation. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

The purpose of this study was to explore knowledge and attitudes about urinary incontinence (UI) among Korean American women with incontinence and provide initial information needed to design education programs and culture-specific interventions. One hundred eighty-two community-dwelling Korean American women who were 30 years and older and self-identified as having UI were invited to participate in the study. Data collection was conducted in 12 Korean religious organizations. This study uses a cross-sectional descriptive design by means of interviews. The Incontinence Quiz was used to measure knowledge and attitudes about UI. Higher scores indicate greater knowledge and more positive attitudes. The mean Incontinence Quiz was 4.85 (SD = 2.75) out of 14, which was much lower than the midpoint of 7.0, indicating that respondents tended to have limited knowledge and negative attitudes toward UI. The number of correct responses to the items on the Incontinence Quiz in this sample was lower than that reported in other studies that sampled the general population. Interventions to improve Korean women's knowledge of, and attitudes toward, UI are needed. WOC and continence nurses should take an active role in educating women about the prevention and treatment of UI.

There has been a paucity of data about the difference in gene expression between melasma lesional skin and normal adjacent one. Our aim was to identify novel genes involved in the pathogenesis of melasma. We performed a microarray analysis and confirmed the results on quantitative real-time polymerase chain reaction (qRT-PCR) in Korean women with melasma. There were 334 genes whose degree of expression showed a significant difference between melasma lesional skin and normal adjacent one. Of these, five were confirmed on qRT-PCR. In melasma lesional skin, there were down-regulation of genes involved in the PPAR signaling pathway and up-regulation of genes involved in neuronal component and the functions of stratum corneum barrier. This result suggests that the pathogenesis of melasma might be associated with novel genes involved in the above signaling pathway in Korean women.

The purpose of the study was to examine the roles of acculturative stress, life satisfaction, and language literacy in depression in non-Korean women residing in South Korea following marriage to Korean men. A cross-sectional study was performed, using an anonymous, self-reporting questionnaire. A total of 173 women were selected using a proportional stratified random sampling method. The relation between acculturation, depression, language literacy, life satisfaction and socio-demographic variables and the predictors of depression among participants were analyzed. The analysis included descriptive statistics and hierarchical multiple regression. Of the participants, 9.2% had depression, which was almost twice the rate of depression found in the general Korean population. In hierarchical multiple regression analysis, acculturative stress (beta=-.325, P<.001) and life satisfaction (beta=-.282, P=.003) were significantly associated with the level of depression. This final model was statistically significant and life satisfaction, acculturative stress, language literacy accounted for 31.0% (adjusted R(2)) of the variance in the depression score (P<.001). Elevated acculturative stress and less life satisfaction were significantly associated with a higher level of depression in migrant wives in Korea. Implications for practice and research are discussed. Copyright © 2013 Elsevier Inc. All rights reserved.

In this study, we identified the factors influencing behavioral intention to undergo Papanicolaou testing among Japanese and Korean women in early adulthood. Their behavioral intentions were compared in this cross-sectional descriptive study. In total, 887 women (Japanese = 498, Korean = 389) aged 20-39 years participated in this study. Using a self-report questionnaire, knowledge, attitudes, subjective norm, perceived behavioral control, and behavioral intention were surveyed. There were significant differences between Japanese and Korean women's scores on all main variables. For Japanese women, all the variables moderately correlated with behavioral intention. In comparison, for Korean women, all independent variables, except for knowledge, moderately correlated with behavioral intention. Through a multiple regression analysis, age, undergoing Papanicolaou testing, attitudes, subjective norm, and perceived behavioral control were identified as significant predictors of behavioral intention among Japanese women. Among Korean women, job status, undergoing a Papanicolaou test, attitudes, subjective norm, and perceived behavioral control were demonstrated as significant predictors of behavioral intention. Health professionals should consider these factors to encourage Papanicolaou testing in women in early adulthood. © 2017 John Wiley & Sons Australia, Ltd.

To prospectively assess the association between sugar-sweetened beverages (SSB), added sugar, and total fructose and serum concentrations of liver enzymes among healthy, reproductive-age women. A prospective cohort of 259 premenopausal women (average age 27.3 ± 8.2 years; BMI 24.1 ± kg/m(2)) were followed up for up to two menstrual cycles, providing up to eight fasting blood specimens/cycle and four 24-h dietary recalls/cycle. Women with a history of chronic disease were excluded. Alanine and aspartate aminotransferases (ALT and AST, respectively) were measured in serum samples. Linear mixed models estimated associations between average SSB, added sugar, and total fructose intake and log-transformed liver enzymes adjusting for age, race, body mass index, total energy and alcohol intake, and Mediterranean diet score. For every 1 cup/day increase in SSB consumption and 10 g/day increase in added sugar and total fructose, log ALT increased by 0.079 U/L (95 % CI 0.022, 0.137), 0.012 U/L (95 % CI 0.002, 0.022), and 0.031 (0.012, 0.050), respectively, and log AST increased by 0.029 U/L (-0.011, 0.069), 0.007 U/L (0.000, 0.014), and 0.017 U/L (0.004, 0.030), respectively. Women who consumed ≥1.50 cups/day (12 oz can) SSB versus less had 0.127 U/L (95 % CI 0.001, 0.254) higher ALT [percent change 13.5 % (95 % CI 0.1, 28.9)] and 0.102 (95 % CI 0.015, 0.190) higher AST [percent change 10.8 % (95 % CI 1.5, 20.9)]. Sugar-sweetened beverages were associated with higher serum ALT and AST concentrations among healthy premenopausal women, indicating that habitual consumption of even moderate SSB may elicit hepatic lipogenesis.

to understand the prenatal genetic testing decision-making processes among pregnant Korean-American women. a qualitative, descriptive research design. referrals and snowball sampling techniques were used to recruit 10 Korean-American women who had been recommended for amniocentesis during pregnancy in the United States (U.S.). All participants were born in Korea and had immigrated to the U.S. The number of years living in the U.S. ranged from 4 to 11 (M=5.7). various regional areas of the U.S. the researchers conducted face-to-face or phone interviews using semi-structured interview guides. The interviews were conducted in the Korean language and lasted approximately 50-100minutes. The interview guides focused on the decision-making process and experiences with prenatal genetic testing, as well as reflections on the decisions. Four core themes emerged related to the participants' decision-making processes, according to their descriptions. These themes are (1) facing the challenges of decision-making, (2) seeking support, (3) determining one's preferred role in the decision-making process, and (4) feeling uncomfortable with the degree of patient autonomy in U.S. health care. researchers concluded that many distinctive factors influence the decision-making processes used by pregnant Korean-American women. The results have the potential to improve shared decision-making practices regarding prenatal genetic testing. clinicians need to understand the sociocultural underpinnings of pregnant Korean-American immigrants regarding prenatal genetic screening and testing as an initial step to engage these patients in shared decision-making.

Regular weight-bearing physical activity has been widely recommended for adult women and may be beneficial in preserving bone mineral density (BMD). However, there is conflicting evidence regarding the effects of resistance training on BMD in premenopausal women. Novel systematic review and meta-analysis evidence is presented on the effects of progressive high-intensity resistance training on BMD in premenopausal women. Structured computer searches of MEDLINE, EMBASE, PubMed, Web of Science, SportDiscus and Evidence Based Medicine Reviews Multifile were undertaken along with hand-searching of key journals and reference lists to locate relevant studies published up to September 2004. Criteria for included studies were published controlled studies and randomised controlled trials (RCTs) evaluating the effects of progressive, high-intensity resistance training studies on BMD in premenopausal women. Two authors reached consensus on all included and excluded studies. Study outcomes for analysis were radiographic BMD assessment from first follow-up at lumbar spine and femoral neck. Primary outcomes for analysis were absolute changes in BMD g/cm(2) at lumbar spine and femoral neck. Relative changes (percentage change) in BMD at lumbar spine were also assessed. Data were extracted from studies including study design, participant characteristics and treatment mode, intensity and duration, using electronic data extraction forms. Where necessary, relevant information was obtained by contacting study authors. Methodological quality of studies was assessed using a well recognised three-question instrument designed to assess bias. Informal assessment for small sample study effects and potential bias was undertaken through visual inspection of funnel plots. The weighted mean difference method (inverse of the variances) was used for combining study group estimates. Quantification of the effect of heterogeneity among study outcomes was assessed using the I(2) statistic. Random

Replication is a critical step to validate positive genetic associations. In this study, we tested two previously reported positive associations. The low density lipoprotein receptor-related protein 5 (LRP5) Val667Met and lumbar spine bone density are replicated. This result is in line with results from large consortiums such as Genomos. However, the estrogen-related receptor alpha (ESRRA) repeat in the promoter is not replicated although the polymorphism studied was functional and could have been a causative variant. We sought to validate associations previously reported between LRP5 V667M polymorphism and lumbar spine (LS, p = 0.013) and femoral neck (FN, p = 0.0002) bone mineral density (BMD), and between ESRRA 23 base pair repeat polymorphism and LS BMD (p = 0.0036) in a sample of premenopausal Caucasian women using an independent sample. For the replication sample, we recruited 673 premenopausal women from the Toronto metropolitan area. All women were Caucasian and had BMD measured. LRP5 V667M was genotyped by allele-specific PCR and ESRRA repeats by sizing of PCR products on agarose gels. We reproduced the same association as we reported previously between LRP5 V667M and LS BMD (p = 0.015) but not with FN BMD (p = 0.254). The combined data from the two populations indicate an effect size of 0.28SD for LS BMD (p = 0.00048) and an effect size of 0.26 SD for FN BMD (p = 0.00037). In contrast, the association we reported earlier between ESRRA repeats and LS BMD was not replicated in the sample from Toronto (p = 0.645). The association between LRP5 V667M and LS BMD is confirmed but not that between ESRRA repeats and LS BMD. This result indicates that it is imperative to validate any positive association in an independent sample.

Isoflavone intake has been associated with a reduction in the risk of cardiovascular disease in postmenopausal women. The aim of the present study was to determine if the effects of isoflavones on vascular function differ between premenopausal and postmenopausal women and between women who smoke and those who do not. Women smokers and nonsmokers who consumed 50 mg of isoflavone/day as black soybean tea for a period of 2 months (n = 55, mean age 39) were enrolled in the present study. We examined endothelial function, which was assessed by the percent change in flow-mediated dilation (%FMD) and arterial wall stiffness using the cardio-ankle vascular index (CAVI), as well as by biochemical parameters of the blood. Neither premenopausal (p = 0.697) nor postmenopausal (p = 0.389) smokers experienced an increase in %FMD after daily consumption of isoflavones. However, both premenopausal (p = 0.004) and postmenopausal (p = 0.019) nonsmokers exhibited a marked elevation in %FMD. By contrast, isoflavone intake effectively reduced CAVI among both premenopausal smokers (p = 0.027) and nonsmokers (p = 0.013), but had no effect on CAVI among postmenopausal smokers (p = 0.169) or nonsmokers (p = 0.128). The women smokers and nonsmokers did not differ in age or %FMD at the time of enrollment in the study. Thus, isoflavones have different effects on vascular endothelial function and arterial wall stiffness in premenopausal and postmenopausal smokers and nonsmokers.

The objective of the study was to explore and describe the health-seeking experience of North Korean women defectors settled in South Korea. A qualitative study was conducted using Colaizzi's phenomenological method. Participants were 10 North Korean women defectors. Data were collected through in-depth, unstructured interviews with individual participants. A total of 24 themes, eight theme clusters, and four categories emerged. The structure of the health-seeking experience for them was identified as 'having new opportunities to better understand my own body and protecting my own health while adapting to the health care system of the South'. The four categories were: finding out about my own body, confusion regarding the medical treatment, enjoying the health care benefits, and protecting my own health. The findings of this study will help improve the understanding of the health-seeking experience of North Korean women defectors and provide valuable resources to assist in caring for their health needs. This will contribute to preparing the groundwork to enhance the quality of their remaining life in South Korea. © 2018 Wiley Periodicals, Inc.

Costs and Benefits of Extended Endocrine Strategies for Premenopausal Breast Cancer.

Background: After completing 5 years of adjuvant tamoxifen, women with estrogen receptor (ER)-positive breast cancer benefit from 5 more years of endocrine therapy, either with tamoxifen or an aromatase inhibitor (AI). For premenopausal women, ovarian ablation (OA) would be required before starting an AI (OA/AI). According to the SOFT/TEXT studies, OA/AI improves 5-year disease-free survival compared with tamoxifen alone, suggesting that OA/AI could be superior to tamoxifen as extended endocrine therapy. The long-term costs and consequences of premature menopause from OA are unknown, but could be estimated through a cost-effectiveness analysis. Methods: A Markov chain Monte Carlo simulation model estimated the costs and benefits of 3 extended endocrine strategies in a hypothetical cohort of premenopausal women with ER-positive early breast cancer: (1) no further treatment; (2) tamoxifen for 5 years (extended tamoxifen); or (3) OA/AI for 5 years. Effectiveness was measured in years of life expectancy gain. Sensitivity analyses accounted for uncertainty surrounding various parameters. Monte Carlo simulation estimated the number of adverse events and deaths from each strategy in the US population over a 40-year period. Results: Extended tamoxifen yielded a higher average life expectancy gain than OA/AI (17.31 vs 17.06 years) at lower average cost ($3,550 vs $14,312). For 18,000 premenopausal ER-positive women, the simulation estimated 13,236, 12,557, and 11,338 deaths with no further treatment, extended tamoxifen, and OA/AI, respectively, but an additional 1,897 deaths from OA, for a total of 13,235 deaths associated with OA/AI. After 24.6 years of follow-up, more women are expected to die from OA/AI than extended tamoxifen. Conclusions: For premenopausal women with ER-positive cancer who have completed adjuvant tamoxifen, another 5 years of tamoxifen is the preferable extended endocrine strategy. The potential long-term health consequences of OA could affect overall

Background In the Suppression of Ovarian Function Trial (SOFT) and the Tamoxifen and Exemestane Trial (TEXT), the 5-year rates of recurrence of breast cancer were significantly lower among premenopausal women who received the aromatase inhibitor exemestane plus ovarian suppression than among those who received tamoxifen plus ovarian suppression. The addition of ovarian suppression to tamoxifen did not result in significantly lower recurrence rates than those with tamoxifen alone. Here, we report the updated results from the two trials. Methods Premenopausal women were randomly assigned to receive 5 years of tamoxifen, tamoxifen plus ovarian suppression, or exemestane plus ovarian suppression in SOFT and to receive tamoxifen plus ovarian suppression or exemestane plus ovarian suppression in TEXT. Randomization was stratified according to the receipt of chemotherapy. Results In SOFT, the 8-year disease-free survival rate was 78.9% with tamoxifen alone, 83.2% with tamoxifen plus ovarian suppression, and 85.9% with exemestane plus ovarian suppression (P=0.009 for tamoxifen alone vs. tamoxifen plus ovarian suppression). The 8-year rate of overall survival was 91.5% with tamoxifen alone, 93.3% with tamoxifen plus ovarian suppression, and 92.1% with exemestane plus ovarian suppression (P=0.01 for tamoxifen alone vs. tamoxifen plus ovarian suppression); among the women who remained premenopausal after chemotherapy, the rates were 85.1%, 89.4%, and 87.2%, respectively. Among the women with cancers that were negative for HER2 who received chemotherapy, the 8-year rate of distant recurrence with exemestane plus ovarian suppression was lower than the rate with tamoxifen plus ovarian suppression (by 7.0 percentage points in SOFT and by 5.0 percentage points in TEXT). Grade 3 or higher adverse events were reported in 24.6% of the tamoxifen-alone group, 31.0% of the tamoxifen-ovarian suppression group, and 32.3% of the exemestane-ovarian suppression group.

The aim of this study was to investigate the characteristics of the risk factors for anorexia nervosa (AN) in Korean women. Two sets of case-control comparisons were conducted, in which 52 women with lifetime AN from Seoul, S. Korea, were compared with 108 Korean healthy controls and also with 42 women with lifetime AN from the UK in terms of their childhood risk factors. A questionnaire designed to conduct a retrospective assessment of the childhood risk factors was administered to all participants. The Korean AN women were more likely to report premorbid anxiety, perfectionism, and emotional undereating and were less likely to report having supportive figures in their childhood than the Korean healthy controls. There were no overall differences in the childhood risk factors between the Korean and British women with AN. Premorbid anxiety, perfectionism, less social support, and emotional undereating merit attention as risk factors in Korean AN. The current results are informative, but an epidemiologically robust prospective case-control study would be needed to validate these findings. © 2009 by Wiley Periodicals, Inc.

Low-fat and low-carbohydrate weight-loss diets can have a beneficial effect on longitudinal measures of blood pressure and blood lipids. We aimed to assess longitudinal changes in blood pressure and blood lipids in a population of premenopausal women. We hypothesized that results may differ by level of adherence to the respective diet protocol and baseline presence of hypertension or hyperlipidemia. Overweight or obese premenopausal women were randomized to a low-fat (n=41) or low-carbohydrate (n=38) diet. As part of the 52-week Lifestyle Eating and Fitness (LEAF) intervention trial, we fit linear mixed models to determine whether a change in outcome differed by treatment arm. Within-group trends in blood pressure and blood lipids did not differ (p>0.30). Across study arms, there was a significant decrease in systolic blood pressure (SBP, 3 mm Hg, p=0.01) over time, but diastolic blood pressure (DBP) did not change significantly over the course of the study. Blood lipids (total cholesterol [TC], low-density lipoproteins [LDL], and high-density lipoproteins [HDL]) all exhibited nonlinear trends over time (p<0.01); each decreased initially but returned to levels comparable to baseline by study conclusion (p>0.20). We observed a decline in SBP among women who were hypertensive at baseline (p<0.01), but hypercholesterolemia at baseline did not affect trends in blood lipids (p>0.40). Our results support that dietary interventions may be efficacious for lowering blood pressure and blood lipids among overweight or obese premenopausal women. However, a decrease in SBP was the only favorable change that was sustained in this study population. These changes can be maintained over the course of a 1-year intervention, yet changes in blood lipids may be less sustainable.

It has been hypothesized that depression and obesity are bi-directionally associated, and when overweight people appear to show a lower risk of depression, this supports the "Jolly Fat" hypothesis. The aim of this study was to examine the "Jolly Fat" hypothesis in middle-aged women in Korea, by different perceived stress levels. We performed a cross-sectional study of 44 to 56 aged Korean women (n = 2201) who underwent a health check-up program at the healthcare centers of Kangbuk Samsung Hospital (Seoul and Suwon centers) in Korea. General and abdominal obesity were defined as body mass index ≥25 kg/m 2 and waist circumference ≥85 cm, respectively. Depressive symptoms were measured by a Korean version of the Center for Epidemiologic Studies-Depression scale. The association between obesity and depressive symptoms was investigated by using multiple logistic regression analyses by different levels of perceived stress, with adjustment for potential confounding factors. The prevalence of general and abdominal obesity and depressive symptoms were 23.7%, 21.4%, and 16.5%, respectively. Women with general obesity were less likely to have depressive symptoms (odds ratio [OR]: 0.50; 95% confidence interval [CI]: 0.25-1.00; p-value: 0.049) in the low-stress group. We also found that women with abdominal obesity had a 60% decrease in the odds of having depressive symptoms (OR: 0.40; 95% CI: 0.18-0.87; p-value: 0.02) in the low-stress group. No significant association was found in the high-stress group. These findings indicate that the relationship between obesity and depressive symptoms in the Korean middle-aged women supports the "Jolly Fat" hypothesis. Further, our results underscore the role of stress as an important potential mediator exerting effects on the association between obesity and depressive symptoms.

Many studies on sexual attitudes and behavior have been performed to improve sexual health. To evaluate changing trends in Korean female sexual life and attitudes in an internet-based survey at 10-year intervals. The survey was targeted toward 20- to 59-year-old women who were asked to complete the questionnaire only if they were sexually active. The survey contained 110 questions about demographic statistics, sexual life, and attitudes that were crafted based on the 2004 study. Results of the 2004 study vs those of the 2014 study. In total, 516 women participated in the study; the questionnaire response rate was 16.0%. The mean frequency of intercourse (FOI) per month was 3.46 ± 2.56 in 2014 vs 5.34 ± 3.84 in 2004. Women in their 20s and 30s in 2014 reported a lower mean FOI than those in 2004. There was no significant difference in the mean FOI in 2004 vs 2014 for women who in their 40s. Risk factors for lower FOI were being older, being single, and having dyspareunia. Most Korean women had positive attitudes toward sex (3.2 ± 0.6 of 5) and considered it as important (3.3 ± 0.7 of 5) as those surveyed in 2004. However, women 20 to 39 years old had less positive attitudes toward sex than in the past decade. Women in their 40s were more active and had more conversations with their partners. Of women using contraceptives, 63.8% were found to use less effective methods, such as intercourse withdrawal and the fertility awareness method. Assessment of changing trends in Korean female sexual life, attitudes, and contraceptive methods could help to establish proper national sexual education programs and campaigns. This study was not a cohort study, because subjects in the 2014 were not identical to those in the 2004 study. Nevertheless, we applied the same inclusion and exclusion criteria for this internet survey, a suitable tool to evaluate the sex life of women, which is often considered a sensitive and private issue in Asian culture. Compared with the 2004 survey

Various exercise interventions have been shown to benefit weight control and general health in different populations. However, very few studies have been conducted on martial arts exercise (MAE). The objective of this pilot study is to evaluate the efficacy of 12 weeks of MAE intervention on body composition, serum biomarkers and quality of life (QOL) in overweight/obese premenopausal women. We found that subjects in the MAE group did not lose body weight, while they significantly decreased fat-free mass and muscle mass as compared to those in the control group, who demonstrated an increase in these parameters. The MAE group demonstrated an increase in serum IGF-I concentration, but no change in others. MAE may be a feasible and effective approach to improve body composition and QOL in overweight/obese premenopausal women. Our study underscores the need for further studies using larger samples to establish possible benefits of MAE in various populations. PMID:24665215

Despite the proven benefits of Pap testing, Korean American women have one of the lowest cervical cancer screening rates in the United States. This study examined how cultural factors are associated with Pap test utilization among Korean American women participants. Quota sampling was used to recruit 202 Korean American women participants residing in New York City. Hierarchical logistic regression was used to assess the association of cultural variables with Pap test receipt. Overall, participants in our study reported significantly lower Pap test utilization; only 58% reported lifetime receipt of this screening test. Logistic regression analysis revealed one of the cultural variables--prevention orientation--was the strongest correlate of recent Pap test use. Older age and married status were also found to be significant predictors of Pap test use. Findings suggest cultural factors should be considered in interventions promoting cervical cancer screening among Korean American women. Furthermore, younger Korean American women and those not living with a spouse/partner should be targeted in cervical cancer screening efforts.

Jackson, Robert T.; Alkahtani, Abdulkareem A.

2018-01-01

Background Saudi women depend on food sources to maintain their serum 25(OH) D concentrations because covering by traditional clothing and time spent indoors limit their sun exposure. Little is known about vitamin D intake and its main food sources in Saudi Arabia. In addition, the association between vitamin D and calcium intake and bone mineral density (BMD) in young women is not well researched. Objectives To assess the adequacy of vitamin D intake among Saudi women as compared to the estimated average requirements (EARs), to identify dietary vitamin D sources, to examine potential determinants of vitamin D intake, and to assess bone health and the association of calcium and vitamin D intake with BMD. Methods This cross-sectional study was conducted in 257 premenopausal women aged 20–50 years in Jeddah, Saudi Arabia. Dietary vitamin D and calcium were assessed by the Semiquantitative Food Frequency Questionnaire. BMD was measured using dual-energy X-ray absorptiometry (DXA) in a subset of women (n=102) at the lumbar spine and femur neck. Results Sixty-five percent of women were below the EAR for vitamin D, and 61% fell below the EAR for calcium. Dairy products, supplements, and fish contributed most to vitamin D intake. Increased age was an independent determinant of sufficient vitamin D intake (p < 0.001). The prevalence of osteopenia was 33% in the lumbar spine and 30% in the femur neck. There was a significant positive association between calcium intake and BMD at the lumbar spine (p=0.043) after controlling for body mass index and energy intake. Vitamin D intake was not significantly different between women with low and normal bone mass. Conclusion Premenopausal women in Jeddah have insufficient vitamin D and calcium intakes. Public health strategies to improve nutrition in young women are needed, and expanding fortification programs to include all dairy products would be useful. PMID:29750126

To examine the adequacy of dietary intake of calcium; folate; and vitamins C, D, E, B-6, and B-12 in premenopausal US women of differing ethnicity. Analyses of single and duplicate 24-hour recalls were conducted to determine dietary intake during the Third National Health and Nutrition Examination Survey. Three thousand five hundred eighty-five randomly selected women aged 20 to 50 years from across the United States who were not pregnant or lactating were examined between 1988 and 1994. Usual nutrient intake distributions were estimated using the Iowa State University method for adjustment of the distribution. The Estimated Average Requirement cut-point method was used to determine the proportion of women with inadequate intake for each nutrient in each ethnic group. More than 75% of women irrespective of ethnic group had usual intakes of calcium lower than the new Adequate Intake. More than 90% of the women had inadequate intakes of folate and vitamin E from food sources alone. More than half of smokers had inadequate intakes of vitamin C. Intakes of vitamins B-6 and B-12 were low in less than 10% of these women. This article provides evidence that a high proportion of premenopausal US women are underconsuming a variety of nutrients. Dietary intakes alone are not currently adequate to meet the new recommended intakes. Nutritional supplement use is widespread and effective, but does not eliminate the concerns for at-risk populations. Awareness of the general inadequacies in intakes of vitamin E and folic acid at large, and in many women vitamin C as well, can help direct individual dietary recommendations and place the emphasis in group counseling on nutrients that are of widespread concern. In addition, foods rich in vitamins B-6 and of general nutritional benefit should be emphasized among African American women in the United States as a substantial proportion of this group is still showing inadequate intakes from foods.

In this focused ethnographic study, we explored the health experiences of 15 Korean immigrant women after retirement in an urban center in Western Canada. Almost all women began their lives in Canada without adequate personal finances, making their employment essential for supporting their families financially. Most women lived with more than two chronic diseases, attributed to long hours and difficult work conditions. They experienced improved psychological health after retiring, irrespective of positive or negative changes in their physical health. Spiritual faith and exercise were important strategies to maintain and enhance their health and to postpone and manage chronic diseases.

Higher circulating prolactin levels have been associated with higher percent mammographic density among postmenopausal women in some, but not all studies. However, few studies have examined associations with dense area and non-dense breast area breast or considered associations with prolactin Nb2 lymphoma cell bioassay levels. We conducted a cross-sectional study among 1,124 premenopausal and 890 postmenopausal women who were controls in breast cancer case-control studies nested in the Nurses' Health Study (NHS) and NHSII. Participants provided blood samples in 1989-1990 (NHS) or 1996-1999 (NHSII) and mammograms were obtained from around the time of blood draw. Multivariable linear models were used to assess the associations between prolactin levels (measured by immunoassay or bioassay) with percent density, dense area, and non-dense area. Among 1,124 premenopausal women, percent density, dense area, and non-dense area were not associated with prolactin immunoassay levels in multivariable models (p trends = 0.10, 0.18, and 0.69, respectively). Among 890 postmenopausal women, those with prolactin immunoassay levels in the highest versus lowest quartile had modestly, though significantly, higher percent density (difference = 3.01 percentage points, 95 % CI 0.22, 5.80) as well as lower non-dense area (p trend = 0.02). Among women with both immunoassay and bioassay levels, there were no consistent differences in the associations with percent density between bioassay and immunoassay levels. Postmenopausal women with prolactin immunoassay levels in the highest quartile had significantly higher percent density as well as lower non-dense area compared to those in the lowest quartile. Future studies should examine the underlying biologic mechanisms, particularly for non-dense area.

Quantities as well as distributions of adipose tissue (AT) are significantly related to cardiovascular disease (CVD) risk factors and can be altered with caloric restriction. This study investigated which cross-sectional slice location of AT is most strongly correlated with changes in CVD risk factors after caloric restriction in obese Korean women. Thirty-three obese pre-menopausal Korean women (32.4 ± 8.5 yrs, BMI 27.1 ± 2.3 kg/m(2)) participated in a 12 weeks caloric restriction program. Subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) were measured using computed tomography (CT) scans at the sites of L2-L3, L3-L4, and L4-L5. Fasting serum levels of glucose, insulin, triglyceride, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), leptin and homeostasis model assessment-insulin resistance (HOMA-IR) were observed. Pearson's partial correlation coefficients were used to assess the relationship between AT measurement sites and changes in CVD risk factors after calorie restriction. When calories were reduced by 350 kcal/day for 12 weeks, body weight (-2.7%), body fat mass (-8.2%), and waist circumference (-5.8%) all decreased (P < 0.05). In addition, following caloric restriction, serum levels of glucose (-4.6%), TC (-6.2%), LDL-C (-5.3%), leptin (-17.6%) and HOMA-IR (-18.2%) decreased significantly (P < 0.05) as well. Changes in VAT at the level of L3-L4 were significantly greater than those at other abdominal sites, and these changes were correlated with changes in TC (P < 0.05), LDL-C (P < 0.001), SBP (P < 0.001) and HOMA-IR (P < 0.01). These results show that VAT at L3-L4 had a stronger correlation with CVD risk factors than with other AT measurement sites after caloric restriction.

We conducted a pilot study to identify whether MRI parameters are sensitive to hormone-induced changes in the breast during the natural menstrual cycle and whether changes could also be observed during an oral contraceptive (OC) cycle. The New York University Langone Medical Center Institutional Review Board approved this HIPAA-compliant prospective study. All participants provided written informed consent. Participants were aged 24-31 years.We measured several non-contrast breast MRI parameters during each week of a single menstrual cycle (among 9 women) and OC cycle (among 8 women). Hormones were measured to confirm ovulation and classify menstrual cycle phase among naturally cycling women and to monitor OC compliance among OC users. We investigated how the non-contrast MRI parameters of breast fibroglandular tissue (FGT), apparent diffusion coefficient (ADC), magnetization transfer ratio (MTR), and transverse relaxation time (T2) varied over the natural and the OC cycles. We observed significant increases in MRI FGT% and ADC in FGT, and longer T2 in FGT in the luteal vs. follicular phase of the menstrual cycle. We did not observe any consistent pattern of change for any of the MRI parameters among women using OCs. MRI is sensitive to hormone-induced breast tissue changes during the menstrual cycle. Larger studies are needed to assess whether MRI is also sensitive to the effects of exogenous hormones, such as various OC formulations, on the breast tissue of young premenopausal women.

Immigrant and minority women are less physically active than White women particularly during leisure time. However, prior research demonstrates that reported household physical activity (PA) and non-leisure time walking/biking were higher among the former. Using accelerometers, GPS, and travel logs, transport-related, home-based, and leisure time PA were measured objectively for 7 days from a convenience sample of 60 first-generation Korean immigrant women and 69 matched White women from the Travel Assessment and Community Project in King County, Washington. Time spent in total PA, walking, and home-based PA was higher among Whites than Korean immigrants regardless of PA type or location. 58 % of the White women but only 20 % of the Korean women met CDC's PA recommendations. Socio-economic status, psychosocial factors, and participants' neighborhood built environmental factors failed to account for the observed PA differences between these groups.

Jumps have been investigated as a stimulus for bone development; however, effects of instruction, jump type, and jump-landing techniques need investigation. This study sought to identify whether ground reaction forces (GRFs) for bilateral vertical jumps (countermovement jumps and drop jumps) with reactive jump-landings (ie, jumping immediately after initial jump-landing), with instruction and with instruction withdrawn, achieve magnitudes and rates of strain previously shown to improve bone mass among premenopausal women. Twenty-one women (Mean ± SD: 43.3 ± 5.9 y; 69.4 ± 9.6 kg; 167 ± 5.5 cm; 27.5 ± 8.7% body fat) performed a testing session 'with instruction' followed by a testing session performed 1 week later with 'instruction withdrawn.' The magnitudes (4.59 to 5.49 body weight [BW]) and rates of strain (263 to 359 BW·s -1 ) for the jump-landings, performed on an AMTI force plate, exceeded previously determined thresholds (>3 BWs and >43 BW·s -1 ). Interestingly, significantly larger peak resultant forces, (↑10%; P = .002) and peak rates of force development (↑20%; P < .001) values (in relation to BW and BW·s -1 , respectively) were observed for the second jump-landing (postreactive jump). Small increases (ES = 0.22-0.42) in all landing forces were observed in the second jump-landing with 'instruction withdrawn.' These jumps represent a unique training stimulus for premenopausal women and achieve osteogenic thresholds thought prerequisite for bone growth.

To expand our understanding of the experience of social role strain in the context of diabetes care among middle-aged married Korean women with type 2 diabetes. Diabetes remains an international concern. There are special challenges experienced by middle-aged married women who may not prioritize self-care and disease management. These challenges may be heightened in certain cultures due to traditional female and family roles along with other social norms and values. Descriptive qualitative study. This qualitative descriptive study involves in-depth interviews conducted between January-February 2007 with ten middle-aged married Korean women purposively selected to represent both higher and lower levels of role strain as measured by the measure of role gratification and strain instrument from the companion study, which was conducted simultaneously. Korean women in this study reported 'resentment regarding previous role strain'. This psychosocial burden was heightened by a noted pattern of 'sacrificing self in favour of others', which complicated both their personal lives and their ability to take care of themselves physically. Added to this were feelings of guilt related to their diabetes and the requirements of day-to-day management expressed as, 'my diabetes makes me a liability'. The women's role-strain experience related to their diabetes was intertwined with their past and current daily life. Further explication and interventions to address and manage role strain could potentially improve women's disease management and overall quality of life. © 2012 Blackwell Publishing Ltd.

To study cross-cultural and intra-cultural differences between the perception and the experience of menopause in pre-menopausal and post-menopausal German and Papua New Guineas women. Concepts concerning menopause and the experience of the menopause were assessed by the symptom categories (i.e. hot flashes, cardiac or sleeping disorders, depression, irritability, lack of drive, vaginal dryness, painful joints or muscles) according to the Menopause Rating Scale (MRS). In addition to the translated English version, a questionnaire in Pidgin-English was offered. Questions about positive and negative expectations of menopause and the acceptance of hormonal replacement therapy were included. Statistical analysis was performed using Chi-square test and the Mann-Whitney U-test as indicated. One hundred and one pre-menopausal and 40 post-menopausal women in Germany as well as 36 pre-menopausal and 41 post-menopausal women in Papua New Guinea were questioned. The expectations regarding the menopause differed significantly in favor of a higher trait intensity concerning the item of hot flashes in Germany and a significantly higher trait intensity in the items cardiac trouble, lack of drive, urological symptoms, vaginal dryness, joint and muscle symptoms in Papua New Guinea. In the menopause experience, significant differences between the cultures are confirmed in favor of a higher trait intensity in Papua New Guinea concerning experienced depression, drop in performance, sexual disturbances and vaginal dryness. The intra-cultural comparison between the concepts concerning menopause and the menopause experience in Germany shows a significantly higher trait intensity with regard to the expected disturbance from hot flashes, depression, agitation, lack of drive and sexual problems as compared to the experienced disturbances. In Papua New Guinea, the survey showed a difference in expected and experienced vaginal dryness. Perception and concepts concerning illness and health are

Prenatal depression is a significant predictor for postpartum depression. However, there is a lack of research on risk factors for Korean women related to prenatal depression and the relationship between prenatal depression during the three trimesters and postpartum depression. Therefore, aims of this study were (1) to identify the prevalence of depression during all three trimesters and the postpartum period, (2) to evaluate the relationship between prenatal depression in each trimester and postpartum depression, and (3) to identify the relationship and differences in prenatal depression based on sociodemographic factors in Korean women. One hundred and fifty three Korean women were recruited from three maternity clinics in Korea. Prenatal and postpartum depressions were evaluated in the first, second (24-26 weeks), third (32-34 weeks) trimester and 4 weeks postpartum with the Edinburgh Postnatal Depression Scale-Korean. The prevalence of depression in the prenatal and postpartum period ranged from 40.5% to 61.4%. Depression in the second and the third trimester was significantly correlated with depression in the postpartum period. Unemployment and household income were risk factors for prenatal depression in the first and second trimesters. To assist women suffering from postpartum depression and prevent its effects, women should be screened for prenatal depression during all three trimesters. For Korean women with high risk factors for prenatal depression, we suggest that the Korean government establish healthcare policies related to depression screening as routine prenatal care and mental health referral systems.

This study aimed to compare seven widely used fall risk assessment tools in terms of validity and practicality, and to provide a guideline for choosing appropriate fall risk assessment tools for elderly Koreans. Sixty community-dwelling Korean older women (30 fallers and 30 matched non-fallers) were evaluated. Performance measures of all tools were compared between the faller and non-faller groups through two sample t-tests. Receiver Operating Characteristic curves were generated with odds ratios for discriminant analysis. Results showed that four tools had significant discriminative power, and the shortened version of Falls Efficacy Scale (SFES) showed excellent discriminant validity, followed by Berg Balance Scale (BBS) with acceptable discriminant validity. The Mini Balance Evaluation System Test and Timed Up and Go, however, had limited discriminant validities. In terms of practicality, SFES was also excellent. These findings suggest that SFES is the most suitable tool for assessing the fall risks of community-dwelling Korean older women, followed by BBS. Practitioner Summary: There is no general guideline on which fall risk assessment tools are suitable for community-dwelling Korean older women. This study compared seven widely used assessment tools in terms of validity and practicality. Results suggested that the short Falls Efficacy Scale is the most suitable tool, followed by Berg Balance Scale.

Metabolic syndrome is a cluster of risk factors for type 2 diabetes mellitus and cardiovascular disease. Associations between metabolic syndrome and several types of cancer have recently been documented. We analyzed the sample cohort data from the Korean National Health Insurance Service from 2002, with a follow-up period extending to 2013. The cohort data included 99 565 individuals who participated in the health examination program and whose data were therefore present in the cohort database. The metabolic risk profile of each participant was assessed based on obesity, high serum glucose and total cholesterol levels, and high blood pressure. The occurrence of cancer was identified using Korean National Health Insurance claims data. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models, adjusting for age group, smoking status, alcohol intake, and regular exercise. A total of 5937 cases of cancer occurred during a mean follow-up period of 10.4 years. In men with a high-risk metabolic profile, the risk of colon cancer was elevated (HR, 1.40; 95% CI, 1.14 to 1.71). In women, a high-risk metabolic profile was associated with a significantly increased risk of gallbladder and biliary tract cancer (HR, 2.05; 95% CI, 1.24 to 3.42). Non-significantly increased risks were observed in men for pharynx, larynx, rectum, and kidney cancer, and in women for colon, liver, breast, and ovarian cancer. The findings of this study support the previously suggested association between metabolic syndrome and the risk of several cancers. A high-risk metabolic profile may be an important risk factor for colon cancer in Korean men and gallbladder and biliary tract cancer in Korean women.

The purpose of this study was to identify the characteristics of anger expression in middle-aged Korean women by categorizing their patterns of expression while considering the complexity and multidimensionality of anger, and by investigating the characteristics relative to the patterns. The research design was a descriptive design using Q methodology, which is a method of measuring subjectivity. A convenience sample of 42 participants aged 40-60 years and living in the community in Korea was recruited. The PC-QUANL software program (a factor analysis program for the Q technique) was used to analyze the Q-sort data. Four factors were extracted that described different expressions of anger among middle-aged Korean women; these factors explained 50.1% of the total variance. The frames of reference of the four factors were a) direct diversion, b) silent masking with remaining anger, c) self digestion, and d) controlling anger with objectification. In this study has identified patterns and characteristics of anger expression among middle-aged Korean women were identified, which will aid the development of effective anger-management programs for controlling anger in this population. In future studies, it would be helpful to investigate how the patterns of anger expression established herein are associated with specific health problems such as cardiovascular disorder and cancer.

Objective: To analyze the rates on prevalence, awareness, status on treatment and control of type 2 diabetes mellitus among Chinese premenopausal women aged 18-49, in 2013. Methods: Data on China Chronic and Non-Communicable Disease Surveillance in year 2013 was used for analysis. Source of data covered 302 surveillance points which were selected by Multi-stage cluster random sampling method that including 176 534 adults over 18 years of age, with 46 674 premenopausal women aged 18-49. Plasma glucose and hemoglobin A1c levels were determined after a 10-hour overnight fast for all the participants, before a 2-hour oral glucose tolerance test was conducted among participants without a self-reported history of diagnosed diabetes. Diabetes was defined according to the 1999 WHO diagnostic criteria-fasting blood glucose level as ≥7.0 mmol/L and/or 2 hours oral glucose tolerance test (OGTT-2 h) level as ≥11.1 mmol/L. After being weighed, according to complex sampling scheme and post-stratification, the sample was used to estimate the rates of prevalence, awareness, treatment and control of type 2 diabetes mellitus by age, education, urban and rural areas, and geographic locations. Results: The overall prevalence of type 2 diabetes mellitus was 5.6% among the Chinese premenopausal women aged 18-49. No statistical difference on the prevalence rates (5.7% and 5.4%, respectively) was seen, between participants from the rural or the urban areas. Prevalence rates in the eastern, central or western geographic areas were 5.8%, 6.2% and 4.4% respectively. The rates of awareness, treatment and control of diabetes appeared as 29.3%, 27.9% and 29.4% in childbearing women aged 18-49. The rate of treatment was 95.4% among those who knew their diabetic situation in childbearing women aged 18-49 years. The control rate of diabetes was 38.9% among those who had taken measures to control glucose, in 18-49-year-old childbearing women. The rate of awareness on diabetes in childbearing

Obesity and metabolic syndrome is a worldwide pandemic and associated with high cardiovascular risk. Metabolic endotoxemia (ME) is thought to be an underlying molecular mechanism. It triggers toll-like receptor 4-mediated inflammatory adipokines and causes a chronic low grade inflammatory status, which results in cardiovascular risk increase. Exercise is the best nonpharmacological treatment to improve prognosis. In this study, we examined the circulating endotoxin level in Korean obese women and investigated effects of exercise on it. Women over body mass index (BMI) 25 kg/m² participated in a resistance training exercise, Curves. At baseline and after 12 weeks exercise, tests including blood samples were taken. In Korean obese women, the fasting endotoxin was 1.45 ± 0.11 EU/mL. Ingestion of a high calorie meal led to a peak level after 2 hours (postprandial 2 hours [PP2]) and a significant rise over the 4 hours (postprandial 4 hours [PP4]) in it (1.78 ± 0.15 and 1.75 ± 0.14 EU/mL for PP2 and PP4, P < 0.05 vs. fasting). After exercise, BMI and hip circumference were reduced significantly. The total cholesterol (TC) at fasting, PP2 and PP4 were decreased significantly. All levels of circulating endotoxin at fasting, PP2 and PP4 showed reduction. But, the peak change was only significant (baseline vs. 12 weeks for PP2; 1.78 ± 0.15 vs. 1.48 ± 0.06 EU/mL, P < 0.05). We report the circulating endotoxin level in Korean obese women for the first time. Also, we establish that energy intake leads to endotoxemia and exercise suppresses the peak endotoxemia after meal. It suggests an impact for a better prognosis in obese women who follow regular exercise.

Menopausal transition and postmenopause are usually associated with changes in body composition and a decrease in physical activity energy expenditure (PAEE). This study investigated body composition, cardiometabolic risk factors, PAEE, and inflammatory markers in premenopausal women after a 10-year follow-up. In all, 102 premenopausal women participated in the 5-year observational longitudinal Montreal Ottawa New Emerging Team (MONET) study. This present substudy included 48 participants (age: 60.0 ± 1.7 years; body mass index: 23.2 ± 2.2 kg/m) 6.0 ± 0.3 years after completion of the initial MONET study. Measures included body composition, waist circumference (WC), fasting glucose and insulin levels, insulin sensitivity (QUICKI model), plasma lipid levels, PAEE, and inflammatory markers. Compared with baseline measures of the MONET study, analyses revealed no significant increase in body weight, although there were significant increases in WC, fat mass (FM), % FM, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol, haptoglobin, apolipoprotein B, ferritin, adiponectin, and soluble cluster of differentiation 14 (all P < 0.001) after the 10-year follow-up. However, significant decreases were observed for fat-free mass, PAEE, fasting glucose levels, interleukin-8 levels, and soluble tumor necrosis factor receptors 1 and 2 (sTNFR-1 and sTNFR-2) levels (all P < 0.05). To determine the effect of postmenopausal years, data were restructured based on final menstrual period (FMP), and one-way analyses of variance were performed.Waist circumference, % FM, total cholesterol, high-density lipoprotein cholesterol, apolipoprotein B, ferritin, adiponectin, and soluble cluster of differentiation 14 were higher in early and late postmenopausal periods in these women. sTNFR-1 and sTNFR-2 levels were higher at the FMP and early postmenopausal years as compared with the late postmenopausal periods.

Understanding how individuals make decisions about Pap tests concerning their personal values helps health-care providers offer tailored approaches to guide patients' decision making. Yet research has largely ignored decision making about Pap tests among immigrant women who experience increased risk of cervical cancer. To explore decision making about Pap tests among Korean immigrant women. We conducted a qualitative descriptive study using 32 semi-structured, in-depth interviews with Korean immigrant women residing in a north-eastern metropolitan area. Data were audio-recorded, transcribed verbatim and analysed using inductive coding. Although most women with positive decisions made their own decisions, some women deferred to their providers, and others made decisions in collaboration with their providers and significant others. While women making positive decisions tended to consider both barriers to and facilitators of having Pap tests, women making negative decisions predominantly discussed the barriers to having Pap tests, such as modesty and differences between the South Korean and US health-care systems. The women's reflections on their decisions differed regarding their Pap test decisions. Women's desired roles in the decision-making process and reflection on their decision outcome appeared to vary, although most participants with positive decisions made their own decisions and were satisfied with their decisions. Future research should conduct longitudinal, quantitative studies to test our findings regarding decision-making processes and outcomes about Pap tests. The findings should be incorporated into cervical cancer screening practices to fulfil the unmet needs of immigrant women in patient-provider communication and to facilitate women's decision making about Pap tests. © 2016 The Authors.

Female sexual dysfunction (FSD) is a public health problem that affects women's quality of life. Although the relationship between some hormones and the FSD has been described, it is not well established for all hormones. Therefore, the aim of our study was to evaluate the association between hormonal dysfunction and sexual dysfunction in premenopausal women. We performed a cross-sectional study with 60 patients with regular menstrual cycles, with age ranging from 18 to 44 years, with previous diagnosis of FSD. All patients were evaluated using the female sexual function index (FSFI) questionnaire and had the levels of total testosterone, prolactin (PRL), thyroid-releasing hormone and free testosterone index measured. Among the 60 patients, 43 (71.7%) were diagnosed with hypoactive sexual desire disorder (HSDD), 9 (15%) had anorgasmy and 8 (3.3%) had sexual pain dysfunction. Hormonal evaluation, demonstrated that 79.1% of patients with HSDD, 78.4% of patients with anorgasmy and 50% of patients with sexual pain dysfunction had female androgen insensitivity. We can conclude that there is an important association between low levels of total and free testosterone and FSD. This finding offers a new alternative for diagnosis and treatment of HSDD. Moreover, given the potential role of androgens in sexual function, randomized controlled trials with adequate long-term follow-up are essential to confirm its possible effect.

Analgesic use has been hypothesized to reduce the risk of some cancers, with inverse associations between analgesics and colon cancer, and suggestive inverse associations for breast cancer. Estrogen metabolites (EM) have genotoxic and estrogenic potential; genotoxicity may differ by hydroxylation pathway. Analgesic use may impact patterns of estrogen metabolism; effects of analgesics on disease risk could be mediated through these patterns. We conducted a cross-sectional study among 603 premenopausal women in the Nurses' Health Study II. Frequency of aspirin, non-aspirin nonsteroidal anti-inflammatory drugs (NSAIDs), and acetaminophen use was reported via questionnaire; average frequency in 1997 and 1999 was calculated. Women provided urine samples between 1996 and 1999, collected during the mid-luteal phase of the menstrual cycle. Urinary EM were quantified using high-performance liquid chromatography-tandem mass spectrometry. We observed no association between analgesic use and estradiol, estrone, or specific pathways of estrogen metabolism. Women reporting more frequent aspirin use had lower methylated 2-catechols (e.g., 2-hydroxyestrone-3-methyl ether, 2+ days/week vs. non-use: 0.95 vs. 1.21 pmol/mg creatinine; p difference = 0.01, p trend = 0.07). Non-aspirin NSAID use was positively associated with 17-epiestriol (4+ days/week vs. non-use: 2.48 vs. 1.52 pmol/mg creatinine; p difference = 0.01, p trend = 0.11). Acetaminophen use was positively associated with total EM (2+ days/week vs. non-use: 236 vs. 198 pmol/mg creatinine; p difference = 0.02, p trend = 0.11), 2-hydroxyestrone-3-methyl ether (1.6 vs. 1.1 pmol/mg creatinine; p difference < 0.01, p trend = 0.02), and 16α-hydroxyestrone (17 vs. 12 pmol/mg creatinine; p difference = 0.01, p trend = 0.05). This study provides the first assessment of analgesic use and patterns of estrogen metabolism in women. While we observed some associations between analgesics and

Instant coffee mixes that contain sugar and non-dairy creamer account for 80-90% of the total coffee market in Korea. The objective of this study was to investigate the relationship between coffee consumption and obesity in Korean women. We included 5995 women who participated in a health screening examination at the Korean National Cancer Center between 2007 and 2016. Daily coffee consumption and the use of sugar and creamer in coffee was evaluated using a 106-item food frequency questionnaire. Obesity was assessed by body mass index (BMI), and abdominal obesity was assessed by waist circumference (WC). A multiple logistic regression model was used to calculate the odds ratio (OR) of obesity according to coffee consumption. After multivariate adjustment, high coffee consumption was positively associated with obesity as measured by BMI (≥3 cups vs. no drinks, OR = 2.52; 95% confidence interval (CI) = 1.91-3.34; p for the trend < 0.001) and abdominal obesity as measured by WC (≥3 cups vs. no drinks, OR = 2.11; 95% CI = 1.59-2.79; p for the trend < 0.001). The positive association between daily coffee consumption and obesity prevalence was not altered by menopause. The amount of coffee with additives consumed per day by Korean women was positively correlated with the prevalence of obesity, but causation cannot be determined due to the cross-sectional nature of the study design. The mechanism underlying the observed relationship is yet to be elucidated.

Previous studies have reported that hyperthyroid and hypothyroid women experience menstrual irregularities more often compared with euthyroid women, but reasons for this are not well-understood and studies on thyroid hormones among euthyroid women are lacking. In a prospective cohort study of euthyroid women, this study characterised the relationship between thyroid hormone concentrations and prospectively collected menstrual function outcomes. Between 2004-2014, 86 euthyroid premenopausal women not lactating or taking hormonal medications participated in a study measuring menstrual function. Serum thyroid hormones were measured before the menstrual function study began. Women then collected first morning urine voids and completed daily bleeding diaries every day for three cycles. Urinary oestrogen and progesterone metabolites (estrone 3-glucuronide (E 1 3G) and pregnanediol 3-glucuronide (Pd3G)) and follicle-stimulating hormone were measured and adjusted for creatinine (Cr). Total thyroxine (T 4 ) concentrations were positively associated with Pd3G and E 1 3G. Women with higher (vs lower) T 4 had greater luteal phase maximum Pd3G (Pd3G = 11.7 μg/mg Cr for women with high T 4 vs Pd3G = 9.5 and 8.1 μg/mg Cr for women with medium and low T 4 , respectively) and greater follicular phase maximum E 1 3G (E 1 3G = 41.7 ng/mg Cr for women with high T 4 vs E 1 3G = 34.3 and 33.7 ng/mg Cr for women with medium and low T 4 , respectively). Circulating thyroid hormone concentrations were associated with subtle differences in menstrual cycle function outcomes, particularly sex steroid hormone levels in healthy women. Results contribute to the understanding of the relationship between thyroid function and the menstrual cycle, and may have implications for fertility and chronic disease. © 2018 John Wiley & Sons Ltd.

STUDY QUESTION Does use of commonly used over-the-counter (OTC) pain medication affect reproductive hormones and ovulatory function in premenopausal women? SUMMARY ANSWER Few associations were found between analgesic medication use and reproductive hormones, but use during the follicular phase was associated with decreased odds of sporadic anovulation after adjusting for potential confounders. WHAT IS KNOWN ALREADY Analgesic medications are the most commonly used OTC drugs among women, but their potential effects on reproductive function are unclear. STUDY DESIGN, SIZE, DURATION The BioCycle Study was a prospective, observational cohort study (2005–2007) which followed 259 women for one (n = 9) or two (n = 250) menstrual cycles. PARTICIPANTS, SETTING, METHODS Two hundred and fifty-nine healthy, premenopausal women not using hormonal contraception and living in western New York state. Study visits took place at the University at Buffalo. MAIN RESULTS AND THE ROLE OF CHANCE During study participation, 68% (n = 175) of women indicated OTC analgesic use. Among users, 45% used ibuprofen, 33% acetaminophen, 10% aspirin and 10% naproxen. Analgesic use during the follicular phase was associated with decreased odds of sporadic anovulation after adjusting for age, race, body mass index, perceived stress level and alcohol consumption (OR 0.36 [0.17, 0.75]). Results remained unchanged after controlling for potential confounding by indication by adjusting for ‘healthy’ cycle indicators such as amount of blood loss and menstrual pain during the preceding menstruation. Moreover, luteal progesterone was higher (% difference = 14.0, −1.6–32.1, P = 0.08 adjusted) in cycles with follicular phase analgesic use, but no associations were observed with estradiol, LH or FSH. LIMITATIONS, REASONS FOR CAUTION Self-report daily diaries are not validated measures of medication usage, which could lead to some classification error of medication use. We were also limited in our

Mammographic Breast Density Evaluation in Korean Women Using Fully Automated Volumetric Assessment

PubMed Central

2016-01-01

The purpose was to present mean breast density of Korean women according to age using fully automated volumetric assessment. This study included 5,967 screening normal or benign mammograms (mean age, 46.2 ± 9.7; range, 30–89 years), from cancer-screening program. We evaluated mean fibroglandular tissue volume, breast tissue volume, volumetric breast density (VBD), and the results were 53.7 ± 30.8 cm3, 383.8 ± 205.2 cm3, and 15.8% ± 7.3%. The frequency of dense breasts and mean VBD by age group were 94.3% and 19.1% ± 6.7% for the 30s (n = 1,484), 91.4% and 17.2% ± 6.8% for the 40s (n = 2,706), 72.2% and 12.4% ± 6.2% for the 50s (n = 1,138), 44.0% and 8.6% ± 4.3% for the 60s (n = 89), 39.1% and 8.0% ± 3.8% for the 70s (n = 138), and 39.1% and 8.0% ± 3.5% for the 80s (n = 12). The frequency of dense breasts was higher in younger women (n = 4,313, 92.3%) than older women (n = 1,654, 59.8%). Mean VBD decreased with aging or menopause, and was about 16% for 46-year-old-Korean women, much higher than in other countries. The proportion of dense breasts sharply decreases in Korean women between 40 and 69 years of age. PMID:26955249

The objective of this study was to characterize cervicovaginal (CV) mucosal factors modulating susceptibility to human immunodeficiency virus (HIV) acquisition in healthy premenopausal (PRE) and postmenopausal (POST) women before and after treatment with estradiol (E2). We compared CV mucosal epithelial histology and immune cells, vaginal microbiota, antimicrobial activity of and soluble mucosal protein concentrations in the CV fluid lavage (CVL), and p24 antigen production after ex vivo infection of ectocervical tissues with HIV-1 BaL among PRE women (n = 20) in the follicular and luteal phases of the menstrual cycle and POST women (n = 17) at baseline and after ∼1 month of treatment with 0.01% vaginal E2 cream. Compared to PRE women, we measured higher levels of p24 antigen after ex vivo infection in tissues from POST women. POST women had a significantly thinner vaginal epithelium with decreased tight junction proteins and a higher density of mucosal immune T cells and lower levels of CD1a antigen-presenting cells, antimicrobial peptides, and inflammatory cytokines in the CVL (p values <.05). POST women had higher vaginal pH and lower vaginal Lactobacilli (p values <.05) than PRE women. After vaginal E2 therapy, CV endpoints and ex vivo HIV replication in POST tissues were similar to those observed in PRE tissues. The CV mucosa in POST women is thinned and compromised, with increased HIV-target immune cells and decreased antimicrobial factors, being more susceptible to HIV infection. After POST women receive topical E2 treatment, mucosal endpoints are similar to PRE levels.

There is sufficient evidence supporting a relationship between increased body mass index (BMI) and an increased risk for breast cancer among postmenopausal women. However, most studies have found a decreased risk for premenopausal breast cancer. This study was conducted to find out the different effects of BMI on the risk of breast cancer among premenopausal and postmenopausal women, and explore the potential factors that influence the associations. A dose-response meta-analysis with 3,318,796 participants from 31 articles was conducted. Cohort studies that included BMI and corresponding breast cancer risk were selected through various databases including PubMed, Medline, Web of Science, the China National Knowledge Infrastructure (CNKI) and Chinese Scientific Journals (VIP). Random effects models were used for analyzing the data. The summary relative risks (RRs) were 1.33 (95%CI: 1.20-1.48) and 0.94(95%CI: 0.80-1.11) among postmenopausal and premenopausal women, respectively. The dose-response meta-analysis indicated a positive non-linear association between BMI and breast cancer risk among postmenopausal women, and compared to the mean level of the normal BMI category (21.5 kg/m 2 ) the RR in total postmenopausal women were1.03 (95% CI: 1.02-1.05) per 1 kg/m 2 increment. However, no statistically significant association among total premenopausal women was detected. In subgroup analysis among European premenopausal women, the summary RR was 0.79(95%CI: 0.70-0.88). The non-linear relationship showed a negative non-linear association between BMI and breast cancer risk among European premenopausal women. When compared to the mean level of the normal BMI category, the RRs were 0.98 (95%CI: 0.96-1.00) per 1 kg/m 2 increment, respectively. In line with previous studies BMI had different effects on pre-menopausal and postmenopausal breast cancer risk. However, contrary to previous studies, a high BMI was not associated with decreased risk in total pre-menopausal women

Endometrial cancer risk is increased by estrogens unopposed by progesterone. In premenopausal women, androgen excess is often associated with progesterone insufficiency, suggesting that premenopausal androgen concentrations may be associated with risk. In a case-control study nested within three cohorts, we assessed the relationship between premenopausal androgens and risk of endometrial cancer (161 cases and 303 controls matched on age and date of blood donation). Testosterone, DHEAS, androstenedione, and SHBG were measured in serum or plasma. Free testosterone was calculated from testosterone and SHBG. We observed trends of increasing risk across tertiles of testosterone (ORT3-T1: 1.59, 95%CI: 0.96, 2.64, p=0.08) and free testosterone (ORT3-T1: 1.76, 95%CI: 1.01, 3.07, p=0.047), which were not statistically significant after adjustment for body mass index (BMI). There was no association for DHEAS, androstenedione, or SHBG. There were significant interactions by age at diagnosis (<55 years, n=51 cases; ≥55 years, n=110 cases). Among women who were ≥55 years of age (predominantly postmenopausal) at diagnosis, the BMI-adjusted OR was 2.08 (95%CI: 1.25, 3.44, p=0.005) for a doubling in testosterone and 1.55 (95%CI: 1.04, 2.31, p=0.049) for a doubling in free testoterone. There was no association among women aged <55 years at diagnosis, consistent with the only other prospective study to date. If pre- and post-menopausal concentrations of androgens are correlated, our observation of an association of premenopausal androgens with risk among women aged ≥55 years at diagnosis could be due to the effect on the endometrium of postmenopausal androgen-derived estrogens in the absence of progesterone, which is no longer secreted.

We surveyed 395 Korean middle-aged women and examined how their perceptions of family relationships, gender-role attitudes, and self-esteem were associated with Hwa-Byung (HB; Korean anger syndrome). Our regression analyses revealed that participants who reported worse family relationship problems experienced more HB symptoms. Having profeminist, egalitarian attitudes toward women's gender roles was also associated with more HB symptoms. Self-esteem was not significantly associated with HB. Based on the results, we suggest that what is crucial to understanding HB is not how women evaluate themselves, but rather the level of stress caused by family relationship problems and their perception of women's roles.

Sarcopenia and insulin resistance are common co-morbidities in the elderly and are known to be associated with vitamin D deficiency. However, no previous studies have investigated interactions between all three of these factors. We aimed to investigate the relationship between 25-hydroxyvitamin D concentration, sarcopenia, and insulin resistance in postmenopausal Korean women. This study used data from the Korea National Health and Nutrition Examination Survey 2008-2011. Participants were 3744 postmenopausal Korean women. Sarcopenia was defined as appendicular skeletal muscle mass divided by body weight >1 standard deviation below the mean for women aged 20-40 years. The serum 25-hydroxyvitamin D and fasting insulin levels were measured, and insulin resistance was calculated using the formula: fasting plasma glucose (mg/dl) × fasting insulin (mIU/l)/405. We found a strong inverse association between 25-hydroxyvitamin D concentration and sarcopenia in postmenopausal Korean women (p = 0.0009). There was also a significant association between sarcopenia and insulin resistance, independent of vitamin D and obesity status (p < 0.0001). However, there was no significant association between 25-hydroxyvitamin D concentration and insulin resistance. In the subgroup analysis, insulin resistance was found to be determined by sarcopenic rather than vitamin D status. Sarcopenia was associated with both insulin resistance and 25-hydroxyvitamin D concentration in postmenopausal Korean women, regardless of obesity status. However, 25-hydroxyvitamin D concentration was not associated with insulin resistance. Sarcopenia is therefore of greater clinical importance due to its close relationship with insulin resistance.

Colorectal cancer incidence is rapidly rising in many Asian countries, with rates approaching those of Western countries. This study aimed to evaluate the prevalence and trends of colorectal adenomas by age, sex, and risk strata in asymptomatic Koreans. Cross-sectional study of 19,372 consecutive participants aged 20 to 79 years undergoing screening colonoscopy at the Center for Health Promotion of the Samsung Medical Center in Korea from January 2006 to June 2009. Among participants at average risk, those without a history of colorectal polyps or a family history of colorectal cancer, the prevalence of colorectal adenomas and advanced adenomas were 34.5% and 3.1%, respectively, in men and 20.0% and 1.6%, respectively, in women. The prevalence of adenomas increased with age in both men and women, with a more marked increase for advanced adenoma. Participants with a family history of colorectal cancer or with a history of colorectal polyps had significantly higher prevalence of adenomas compared with participants of average risk (36.9% vs. 26.9%; age- and sex-adjusted prevalence ratio = 1.16; 95% confidence interval, 1.09-1.22). The prevalence of adenomas increased annually in both men and women. In this large study of asymptomatic Korean men and women participating in a colonoscopy screening program, the prevalence of colorectal adenomas was comparable and possibly higher than previously reported in Western countries. Cost-effectiveness studies investigating the optimal age for starting colonoscopy screening and etiological studies to identify the reasons for the increasing trend in colorectal adenomas in Koreans are needed. ©2014 AACR.

Osteoporosis, a slowly evolving public health epidemic, often with an insidious presentation is largely preventable but the optimal dimensions of exercise that may be prescribed for enhancing bone-health among premenopausal adults are yet to be elucidated. Hence, the escalating incidence and burden of prevalence of osteoporosis is yet unabated. Considering that exogenous hormones in the form of hormonal contraception are known to modulate bone mass, investigations of their possible influence on the translation of exercise-induced osteogenic stimuli on the mature bone is pertinent. The aim of this study was to examine the effect of specified lifestyle exercise on bone-health of premenopausal women. Premenopausal women (n = 96, mean age: 22.25 ± 3.5 years; mean BMI: 23.43 ± 3.5 kg/m(2)) participated in a 6-month randomised controlled trial involving home-based rest-interspersed bouts of high-impact exercise for the intervention group and sham exercise for the control group. Approximately half (47) of the participants (24-exercise, 23-control) were on hormonal-based contraception while the other half (49: 24-exercise, 25-control) were not on hormonal contraception. The regime led to a significant 3.7 % increase in broadband ultrasound attenuation of exercisers compared to controls; hormonal contraceptive use did not appear to potentiate the osteogenic effects of the lifestyle exercise regime. The research highlights that short, discrete bouts of high-impact exercise may be a potential public health prescription for enhancing premenopausal bone-health regardless of hormonal contraceptive use.

What is the current status of ovarian suppression/ablation in women with premenopausal early-stage breast cancer?

PubMed

Higgins, Michaela J; Davidson, Nancy E

2009-01-01

The role of ovarian suppression/ablation (OS/OA) in premenopausal women with hormone receptor-positive breast cancer has been evolving for more than a century. It is clear that OS/OA is an effective adjuvant therapy for these women, but despite numerous studies enrolling thousands of women, many unanswered questions remain. In particular, a major question is whether additional benefit is gained with combination treatment comprising luteinizing hormone-releasing hormone (LH-RH) agonists and tamoxifen over tamoxifen alone. Ongoing trials also are assessing the coupling of aromatase inhibitors (traditionally contraindicated in these patients because of paradoxic stimulation of estrogen production) and LH-RH agonists. Any potential disease-free or overall survival advantage of combination treatment must be balanced against a possible increase in adverse effects and impairment of quality of life. This review focuses on new data on how to incorporate OS/OA into the rational treatment of this challenging patient population.

Pregnancy and lactation have been associated with decline in bone mineral density (BMD). It is not clear if there is a full recovery of BMD to baseline. This study sought to determine if pregnancy or breast-feeding or both have a cumulative effect on BMD in premenopausal and early postmenopausal women. We performed single-center cohort analysis. Five hundred women aged 35-55 years underwent routine BMD screening from February to July 2011 at a tertiary medical center. Patients were questioned about number of total full-term deliveries and duration of breast-feeding and completed a background questionnaire on menarche and menopause, smoking, dairy product consumption, and weekly physical exercise. Weight and height were measured. Dual-energy X-ray absorptiometry was used to measure spinal, dual femoral neck, and total hip BMD. Associations between background characteristics and BMD values were analyzed. Sixty percent of the women were premenopausal. Mean number of deliveries was 2.5 and mean duration of breast-feeding was 9.12 months. On univariate analysis, BMD values were negatively correlated with patient age (p=0.006) and number of births (p=0.013), and positively correlated with body mass index (p<0.001). On multiple (adjusted) logistic regression analysis, prolonged breast-feeding duration, but not number of deliveries, was significantly correlated to a low BMD (p=0.008). An effect was noted only in postmenopausal women. The spine was the most common site of BMD decrease. Prolonged breast-feeding may have a deleterious long-term effect on BMD and may contribute to increased risk of osteoporosis later in life. Copyright © 2013 Elsevier Ireland Ltd.

This study aimed to compare factors related to changes in perceived health status of Han Chinese (traditional Chinese) and Korean-Chinese (Chinese nationals of Korean descent) women after immigration to Korea. During summer 2013, a survey was conducted with 151 Han and 158 Korean-Chinese women married to Korean men. Most of the respondents reported either no changes (82%) or positive changes (18%) in their perceived health status after immigration. The results of the multiple logistic regression analyses indicated healthy dietary behavior was related to positive changes in the perceived health status of both groups (odds ratio [OR] = 7.4 for Han Chinese; OR = 14.6 for Korean-Chinese). Among Han Chinese women, the length of residence in Korea and the change in perceived health status showed a negative relation (OR = 0.2). In contrast, their level of acculturation and health perception were positive (OR = 7.5). However, these results did not apply to the Korean-Chinese women. In conclusion, factors related to changes in perceived health status differed between the 2 groups although they shared healthy dietary behaviors as a common factor. Therefore, policies and programs aimed at promoting immigrant women's health should consider the differences between Han Chinese and Korean-Chinese. © 2016 APJPH.

Menstrual cycle characteristics are markers of endocrine milieu. However, associations between age at menarche and adulthood sex steroid hormone levels have been inconsistent, and data on menstrual characteristics and non-sex steroid hormones are sparse. We assessed the relations of menstrual characteristics with premenopausal plasma sex steroid hormones, sex hormone binding globulin (SHBG), prolactin, and growth factors among 2,745 premenopausal women (age 32-52) from the Nurses' Health Study II. Geometric means and tests for trend were calculated using multivariable general linear models. Early age at menarche was associated with higher premenopausal early-follicular free estradiol (percent difference < 12 vs. > 13 years = 11%), early-follicular estrone (7%), luteal estrone (7%), and free testosterone (8%) (all p trend  < 0.05). Short menstrual cycle length at age 18-22 was associated with higher early-follicular total (< 26 vs. > 39 days = 18%) and free estradiol (16%), early-follicular estrone (9%), SHBG (7%), lower luteal free estradiol (- 14%), total (- 6%), and free testosterone (- 15%) (all p trend  < 0.05). Short adult menstrual length was associated with higher early-follicular total estradiol (< 26 vs. > 31 days = 14%), SHBG (10%), lower luteal estrone (- 8%), progesterone (- 9%), total (- 11%) and free testosterone (- 25%), and androstenedione (- 14%) (all p trend  < 0.05). Irregularity of menses at 18-22 was associated with lower early-follicular total (irregular vs. very regular = - 14%) and free estradiol (- 14%), and early-follicular estrone (- 8%) (All p trend  < 0.05). Irregularity of adult menstrual cycle was associated with lower luteal total estradiol (irregular vs. very regular = - 8%), SHBG (- 3%), higher total (8%), and free testosterone (11%) (all p trend  < 0.05).

Iron deficiency anemia (IDA) is one of the most common nutritional disorders in the world. In the present study, we evaluated erythrocyte membrane fatty acid composition in premenopausal patients with IDA. Blood samples of 102 premenopausal women and 88 healthy control subjects were collected. After the erythrocytes were separated from the blood samples, the membrane lipids were carefully extracted, and the various membrane fatty acids were measured by gas chromatography (GC). Statistical analyses were performed with the SPSS software program. We used blood ferritin concentration <15 ng/mL as cut-off for the diagnosis of IDA. The five most abundant individual fatty acids obtained were palmitic acid (16:0), oleic acid (18:1, n-9c), linoleic acid (18:2, n-6c), stearic acid (18:0), and erucic acid (C22:1, n-9c). These compounds constituted about 87% of the total membrane fatty acids in patients with IDA, and 79% of the total membrane fatty acids in the control group. Compared with control subjects, case patients had higher percentages of palmitic acid (29.9% case versus 25.3% control), oleic acid (16.8% case versus 15.1% control), and stearic acid (13.5% case versus 10.5% control), and lower percentages of erucic acid (11.5% case versus 13.6% control) and linoleic acid (15.2% case versus 15.4% control) in their erythrocyte membranes. In conclusion, the total-erythrocyte-membrane saturated fatty acid (SFA) composition in premenopausal women with IDA was found to be higher than that in the control group; however, the total-erythrocyte-membrane unsaturated fatty acid (UFA) composition in premenopausal women with IDA was found to be lower than that in the control group. The differences in these values were statistically significant.

To assess age- and site-related bone mineral density (BMD) values in Korean female patients with a distal radius fracture, and to compare them with those of the community-based general Korean female population. For this study, we recruited 54 consecutive Korean women, 50 to 79 years of age, with a distal radius fracture caused by minor trauma. We performed dual-energy x-ray absorptiometry scans at central sites: the lumbar spine, femoral neck, trochanter, and Ward's triangle, which is a triangular area within the femoral neck. Age- and site-related BMDs were assessed and compared with those of population-based reference data for Korean women. The overall prevalence (defined as meeting the osteoporosis criteria in at least one of the earlier-described measurement areas) of osteoporosis in patients with a distal radius fracture was 57%. The site-related prevalence was 54% at Ward's triangle, 43% at the lumbar spine, 32% at the femoral neck, and 26% at the trochanter, and these values were individually statistically significantly higher than those of the general Korean female population except for the lumbar spine. In patients 50 to 59 and 70 to 79 years of age, patients' mean BMD values at the hip were statistically significantly lower than those of the reference female population of corresponding age groups, but the hip BMD differences were not statistically significant in patients 60 to 69 years of age. There were no statistically significant BMD differences measured at the lumbar spine in any age group. Korean female patients with a distal radius fracture, 50 to 59 and 70 to 79 years of age, had lower BMDs at the hip than the reference Korean female population. However, no statistically significant BMD differences were found in those 60 to 69 years of age. Low BMD may have a greater impact on distal radius fracture in women younger than 60 years of age or over 70 years of age. Considering the young onset of bone loss, patients younger than 60 years of age with a

This study aimed to explore the effectiveness of logo-autobiography (LA) as a therapeutic modality for Korean immigrant women suffering from depression and perceiving their lives as meaningless. A nonrandomized quasi-experimental study was conducted with pretest, posttest, and a 4-week follow-up test. Forty subjects--20 with antidepressants and 20 without--were divided quarterly and assigned to the experimental group and the control group. The experimental group reported a significant lower score on depressive symptoms (F = 6.832, p = .013; F = 19.800, p ≤ .001) and a higher score on meaning of life (F = 12.294, p = .001; F = 12.232, p = .001) than did the control group immediately after completing the LA and a 4-week follow-up. The LA was more effective for the subjects in the nonmedication group than in the medication group. In conclusion, LA is effective in reducing depressive symptoms and increasing a sense of meaning in life among Korean immigrant women suffering from depression.

The research of carcinogenetic mechanisms of breast cancer in different ethnic backgrounds is an interesting field, as clinical features of breast cancers vary among races. High premenopausal incidence is distinctive in East-Asian breast cancer. However, human cell lines derived from Asian primary breast tumor are rare. To provide alternative cell line models with a relevant genetic background, we aimed to establish breast cancer cell lines from Taiwanese patients of Han-Chinese ethnicity. Fresh tissue from mammary tumors were digested into organoids, plated and grown in basal serum-free medium of human mammary epithelial cells (HuMEC) with supplements. Cells were further enriched by positive selection with CD326 (epithelial cell adhesion molecule; EpCAM)-coated micro-magnetic beads. Two breast cancer cell lines derived from premenopausal women were successfully established by this method, and named Chang-Gung Breast Cancer 01 (CGBC 01) and 02 (CGBC 02). These two cell lines had a similar phenotype with weak expression of estrogen receptor (ER), progesterone receptor (PR), and without amplification of receptor tyrosine protein kinase erbB-2 (HER2/neu). Genome-wide Single Nucleotide Polymorphism (SNP) array showed multiple copy number alterations in both cell lines. Based on gene expression profiles, CGBC 01 and 02 were clustered into basal-like subtype with reference to the breast cancer cell line gene expression database. The tumorigenicity of both cell lines was extremely low in both anchorage-independence assay and transplantation into the mammary fat pads of nude mice. CGBC 01 and CGBC 02 are low tumorigenic breast cancer cell lines, established from Han-Chinese premenopausal breast cancer patients, which serve as in vitro models in studying the biological features of Asian breast cancer.

Menopause constitutes a significant cause of bone loss, and it is currently debated whether bone mass is preserved or begins to decline substantially before that time in women. We used pQCT of the tibia to estimate differences of bone mineral mass, bone geometry and derived strength between premenopausal and postmenopausal Caucasian women of different age-groups per decade of age (20-79y). For each individual, we assessed total, trabecular and cortical bone mineral content (BMC, mg) and volumetric bone mineral density (BMD, mg/cm3); total and cortical cross-sectional areas (CSA, mm2); periosteal circumference (PERI_C, mm); endosteal circumference (ENDO_C, mm); mean cortical thickness (CRT_THK, mm); and Stress-Strain Index (SSI). Comparisons were made both between premenopausal (N=84) and postmenopausal (N=231) women as distinct groups, and among women of the different age-groups. Our results indicated that premenopausal women had significantly higher trabecular and cortical BMC and vBMD, with higher cortical CSA, CRT_THK and SSI than postmenopausal women. Moreover, significant differences of trabecular but not cortical BMC, vBMD or SSI were found between women of the younger (<48y) age-groups. PERI_C, ENDO_C displayed lower values in the 20-29y group and higher values in the 70-79y group, denoting significant differences of bone geometry with aging. PMID:27282455

Osteoporosis is one of the commonest metabolic diseases of bone. Its possible causes may include thyroid hormonal dysfunction. The objective of this study was to evaluate the effects of hyperthyroidism and hypothyroidism on osseous tissue metabolism in premenopausal women. 38 women with hyperthyroidism, 40 with hypothyroidism and 41 healthy women participated in this study. Initially after 6 and 12 months, each patient underwent selected hormonal, immunological and biochemical tests, measurement of concentrations of bone turnover markers and densitometry were also performed. On initial evaluation, lower cortical bone density was found in patients with hyperthyroidism (femoral neck). After 12 months, an increase in BMD was seen, but it was still lower than in the control group. Statistically significantly higher concentrations of bone turnover markers, decreasing from the sixth month of treatment, were noted only in the group with hyperthyroidism. Statistically significant differences were not noted in the femoral neck nor in the lumbar spine BMD in patients with hypothyroidism. Hyperthyroidism poses a negative effect on bone metabolism. Hypothyroidism in premenopausal females does not have any influence on bone density.

This study were to assess the relationships among BMI, body weight perception, and efforts to lose weight in a public sample of Korean women who are overweight and obese and to examine the mediating role of body weight perception on the relationship between BMI and weight loss efforts. This cross-sectional study used data from the 2008 Korea National Health and Nutrition Examination Survey. The sample was 1,739 Korean women 20 years old or older with body mass index (BMI) ≥ 23 kg/m(2). Bivariate relationships among variables of interests were assessed. Three separate regressions were used to test the mediating role of body weight perception on the relationship between BMI and weight loss efforts. BMI and body weight perception were significant correlates of weight loss efforts. BMI was significantly associated with weight perception, but a large proportion of women underestimated their weight. Weight perception partially mediated the relationship between BMI and weight loss efforts in Korean women. In light of the high prevalence of overweight or obesity and the many health consequences associated with obesity, Korean women should be aware of a healthy body weight and try to achieve that weight. Nursing interventions should consider body weight perception to effectively motivate overweight and obese Korean women to lose weight, as necessary. Copyright © 2013. Published by Elsevier B.V.

Knowledge, barriers, and motivators related to cervical cancer screening among Korean-American women. A focus group approach.

Cervical cancer is a significant health problem for Korean-American women. It currently is the number one female cancer diagnosed among women in South Korea. Despite this fact, Korean-American women have very low rates of cervical cancer screening. The purpose of this research were to gain an understanding of Korean women's knowledge about cervical cancer, and to identify major barriers to early screening for cervical cancer and the motivators for prevention and early detection. It is hoped that the findings will guide the development of community-based cervical cancer education and screening programs for adult Korean-American women. The health belief model (HBM) provided the theoretical basis for the study. A qualitative study with eight focus groups (n = 102) was conducted using 11 questions derived from the HBM. Focus group discussions revealed that there was misinformation and a lack of knowledge about cervical cancer. The women therefore were confused about the causative factors and preventive strategies related to cervical cancer. The findings showed that major structural barriers were economic and time factors along with language problems. Many participants were recent immigrants with no medical insurance and long work hours. The main psychosocial barriers were fear/fatalism, denial, and Confucian thinking. Participants stated that medical advice and education would influence them most to undergo a Pap test. Recommendations were made to reduce certain barriers and to increase knowledge and motivations.

Hormonal fluctuations during the menstrual cycle influence energy intake and expenditure as well as eating preferences and behavior. We examined the effect in healthy, overweight, premenopausal women of a diet and exercise weight-loss program that was designed to target and moderate the effects of the menstrual cycle compared with the effect of simple energy restriction. A total of 60 healthy, overweight, premenopausal women were included in a 6-mo weight-loss program in which each subject consumed a diet of 1600 kcal/d. Subjects were randomly assigned to either a combined diet and exercise program that was tailored to metabolic changes of the menstrual cycle (Menstralean) or to undergo simple energy restriction (control). Thirty-one women (19 Menstralean and 12 control women) completed the study [mean ± SD body mass index (in kg/m(2)): 32.0 ± 5.2]. Both groups lost weight during the study. In an intention-to-treat analysis, the Menstralean group did not achieve a clinically significant weight loss compared with that of the control group (P = 0.61). In per-protocol analyses, a more-pronounced weight loss of 4.3 ± 1.4 kg (P = 0.002) was shown in adherent Menstralean subjects than in the control group. A differentiated diet and exercise program that is tailored to counteract food cravings and metabolic changes throughout the menstrual cycle may increase weight loss above that achieved with a traditional diet and exercise program in women who can comply with the program.

Objective Based on the hypothesis that high-meat diets may increase breast cancer risk through hormonal pathways, this analysis compared estrogens in serum and urine by meat-eating status. Design Intervention with repeated measures. Setting Two randomized soy trials (BEAN1 and BEAN2) among premenopausal healthy women. Subjects BEAN1 participants completed 7 unannounced 24-hour dietary recalls and donated 5 blood and urine samples over 2 years. BEAN2 women provided 7 recalls and 3 samples over 13 months. Serum samples were analyzed for estrone (E1) and estradiol (E2) using radioimmunoassays. Nine estrogen metabolites were measured in urine by liquid chromatography mass spectrometry. Semi-vegetarians included women who reported <30 g/day of red meat, poultry, and fish and pescatarians who consumed <20 g/day of meat/poultry but >10 g/day of fish. All other women were classified as non-vegetarians. We applied mixed models to compute least-square means by vegetarian status adjusted for potential confounders. Results The mean age of the 272 participants was 41.9±4.5 years. Serum E1 (85 vs 100 pg/mL, p=0.04) and E2 (140 vs 154 pg/mL, p=0.04) levels were lower in the 37 semi-vegetarians than in the 235 non-vegetarians. The sum of the 9 urinary estrogen metabolites (183 vs 200 pmol/mg creatinine, p=0.27) and the proportions of individual estrogens and pathways did not differ by meat-eating status. Restricting the models to the samples collected during the luteal phase strengthened the associations. Conclusions Given the limitations of this study, the lower levels of serum estrogens in semi-vegetarians than non-vegetarians need confirmation in larger populations. PMID:24050121

To compare the intake of women who report varying levels of frequency of consuming food at commercial facilities outside the home. A 1-week descriptive study of dietary intake in women. Subjects completed daily diet records that included information regarding the source of the food eaten at each meal or snack. The sample was divided on the basis of the number of meals each subject reported obtaining from a commercial establishment outside the home. Of the 129 subjects, 56% (n = 72) reported eating out 5 times or less during the week of recording (Low Eating Out group) and the remainder (n = 57) reported eating out between 6 and 13 times (High Eating Out group) One hundred twenty-nine premenopausal women were recruited via community advertising for an investigation of health habits. This study was conducted in a midsouthern US city. Results were analyzed using independent sample t tests and chi 2 tests. Mean intake was compared for the groups. The High Eating Out group was found to be consuming significantly more total energy (2,057 kcal vs 1,769 kcal; P = .002), fat (79.5 g vs 60.6 g; P < .001), and sodium (3,299 mg vs 2,903 mg; P = .043) and marginally more carbohydrate (261.5 g vs 234.6 g; P = .055) and protein (71.5 g vs 65.4 g; P = .066). Total fiber or calcium intake did not differ between the groups. Our study demonstrates that women who report eating out a greater number of times per week report more total energy intake as well as higher fat and sodium intakes. However, the High Eating Out group did not consume significantly more fiber or calcium in the extra energy consumed.

BACKGROUND The cause of acute uncomplicated cystitis is determined on the basis of cultures of voided midstream urine, but few data guide the interpretation of such results, especially when gram-positive bacteria grow. METHODS Women from 18 to 49 years of age with symptoms of cystitis provided specimens of midstream urine, after which we collected urine by means of a urethral catheter for culture (catheter urine). We compared microbial species and colony counts in the paired specimens. The primary outcome was a comparison of positive predictive values and negative predictive values of organisms grown in midstream urine, with the presence or absence of the organism in catheter urine used as the reference. RESULTS The analysis of 236 episodes of cystitis in 226 women yielded 202 paired specimens of midstream urine and catheter urine that could be evaluated. Cultures were positive for uropathogens in 142 catheter specimens (70%), 4 of which had more than one uropathogen, and in 157 midstream specimens (78%). The presence of Escherichia coli in midstream urine was highly predictive of bladder bacteriuria even at very low counts, with a positive predictive value of 102 colony-forming units (CFU) per milliliter of 93% (Spearman’s r = 0.944). In contrast, in midstream urine, enterococci (in 10% of cultures) and group B streptococci (in 12% of cultures) were not predictive of bladder bacteriuria at any colony count (Spearman’s r = 0.322 for enterococci and 0.272 for group B streptococci). Among 41 episodes in which enterococcus, group B streptococci, or both were found in midstream urine, E. coli grew from catheter urine cultures in 61%. CONCLUSIONS Cultures of voided midstream urine in healthy premenopausal women with acute uncomplicated cystitis accurately showed evidence of bladder E. coli but not of enterococci or group B streptococci, which are often isolated with E. coli but appear to rarely cause cystitis by themselves.

The role of vegetable consumption in relation to breast cancer risk is controversial. Anticarcinogenic compounds may be present only in specific vegetables, thereby attenuating findings for total vegetable intake. Cruciferous vegetables contain precursors of isothiocyanates (ITCs), which may be chemopreventive through potent inhibition of phase I, and induction of phase II enzymes, such as glutathione S-transferases (GSTs). We investigated associations between consumption of cruciferous vegetables, sources of ITCs, and breast cancer risk, and potential modification of relations by GSTM1 and GSTT1 genotypes. Cases (n = 740) were Caucasian women with incident breast cancer identified from all major hospitals in Erie and Niagara counties. Community controls (n = 810) were frequency matched to cases by age and county. An in-depth interview including a validated FFQ was administered in person. Odds ratios (ORs) and 95% CIs were used to estimate relative risks. Consumption of cruciferous vegetables, particularly broccoli, was marginally inversely associated with breast cancer risk in premenopausal women [4th quartile OR = 0.6, 95% CI (0.40-1.01), P = 0.058]. Associations were weaker or null among postmenopausal women. No significant effects of GST genotype on risk were observed in either menopausal group. These data indicate that cruciferous vegetables may play an important role in decreasing the risk of premenopausal breast cancer.

Obesity is a major risk factor for several cancers, including female cancers. Endogenous hormones and inflammatory factors may mediate the association between anthropometric measures and cancer risk, although these associations have been studied mainly in Caucasians. The aim of the current study was to explore the association of circulating hormones, adipokines, and inflammatory factors with obesity and overweight in premenopausal Mexican women. We conducted a cross-sectional analysis of 504 premenopausal women from the large Mexican Teachers' Cohort (MTC, ESMaestras) study to determine the association of insulin-like growth factor I (IGF-I), its major circulating binding protein (IGFBP-3), leptin, adiponectin, C-peptide, and C-reactive protein with comprehensive measures of body size. Biomarkers were measured by immunoassays. Multivariate regression analyses were performed to compare geometric mean biomarker concentrations with measured markers of body size and adiposity. Mean IGF-I and IGFBP-3 concentrations significantly increased with increasing height and leg length. Concentrations of IGF-I, adiponectin, and the IGF-I/IGFBP-3 ratio strongly decreased with increasing BMI, weight, waist and hip circumferences, waist-to-hip ratio (WHpR), and waist-to-height ratio (WHtR), while CRP, leptin, C-peptide concentrations, and the leptin/adiponectin ratio strongly increased. Adiponectin and the leptin/adiponectin ratio remained significantly related to measures of central adiposity (waist circumference, WHpR, and WHtR) after adjustment by body mass index. The results of our study suggest a strong relation between biomarkers and body size in this study population and suggest that different fat depots may have different metabolic properties.

Caffeine has been suggested as a possible risk factor for breast cancer, potentially through its effect of facilitating the development of benign breast disease. However, coffee and tea also contain polyphenols, which exhibit anticarcinogenic properties. A hospital-based, case-control study was conducted to evaluate the role of coffee, decaffeinated coffee, and black tea in breast cancer etiology. Study participants included 1932 cases with primary, incident breast cancer and 1895 hospital controls with nonneoplastic conditions. All participants completed a comprehensive epidemiological questionnaire. Among premenopausal women, consumption of regular coffee was associated with linear declines in breast cancer risk (P for trend = 0.03); consumers of >or=4 cups/d experienced a 40% risk reduction (odds ratio = 0.62, 95% CI 0.39-0.98). No clear associations between intake of black tea or decaffeinated coffee and breast cancer risk were noted among premenopausal women, although black tea was associated with a protective effect unique to a subsample of cases with lobular histology. Among postmenopausal women, breast cancer risk was not associated with consumption of coffee, tea, or decaffeinated coffee. Results among postmenopausal women did not differ by histologic subtype. Our findings support a protective effect of coffee intake on premenopausal, but not postmenopausal breast cancer risk. Further studies are warranted to confirm these findings.

Vitamin D has been identified as a weak protective factor for postmenopausal breast cancer (relative risk [RR]~0.9), while high breast density has been identified as a strong risk factor (RR~4–6). To test the hypothesis that there is an association between vitamin D intake, but not circulating vitamin D levels, and mammographic breast density among women in our study we conducted a cross-sectional study of 165 screening mammography patients at Nashville General Hospital’s Breast Health Center (NGH-BHC), a public facility serving medically indigent and underserved women. Dietary and total (dietary plus supplements) vitamin D, calcium intakes were estimated by the AAFQ and blood samples were analyzed for 25-Hydroxyvitamin D [25(OH)D3]. Average percent breast density for the left and right breasts combined was estimated from digitized films using an interactive-thresholding method available through Cumulus software. After statistical adjustment for age, race and body mass index, the results revealed there were significant trends of decreasing breast density with increasing vitamin D and calcium intake among premenopausal, but not among postmenopausal women. There was no association between serum vitamin D and breast density in pre- or postmenopausal women. Confirmation of our findings in larger studies may assist in clarifying the role of vitamin D in breast density. PMID:26321093

Effect of alcohol consumption on hormones involved in carbohydrate and lipid metabolism in premenopausal women

Alcohol consumption alters carbohydrate and lipid metabolism which are in part regulated by pancreatic and adrenal hormones. The menstrual cycle per se produces changes in several peptide and steroid hormones besides the sex hormones. The authors investigated the effect of moderate alcohol consumption on plasma hormone levels in 40 premenopausal women. The subjects were fed controlled diets containing 35% of calories from fat. In a random crossover design women were given either alcohol or a soft-drink of equal caloric value for 3 menstrual cycles. Fasting blood samples were collected in the third cycle during follicular, ovulatory and luteal phases. Plasmamore » dehydroepiandrosterone-sulphate (DHEA-S), insulin, glucagon and cortisol levels were measured by radioimmunoassay. Moderate alcohol consumption had no effect on plasma insulin and DHEA-S levels but significantly increased glucagon and cortisol levels. Menstrual cycle per se affected plasma glucagon level in that the levels were higher during follicular phase than luteal phase. Thus, changes in carbohydrate and lipid metabolism following alcohol consumption are mediated in part by alterations in hormones involved in their metabolism.« less

Ferritin levels have been associated with metabolic syndrome and insulin resistance. The aim of the present study was to evaluate the prediction of ferritin levels by variables related to cardiometabolic disease risk in a multivariate analysis. For this aim, 123 healthy women (72 premenopausal and 51 posmenopausal) were recruited. Data were collected through procedures of anthropometric measurements, questionnaires for personal/familial antecedents, and dietary intake (24-h recall), and biochemical determinations (ferritin, C reactive protein (CRP), glucose, insulin, and lipid profile) in blood serum samples obtained. Multiple linear regression analysis was used and variables with no normal distribution were log-transformed for this analysis. In premenopausal women, a model to explain log-ferritin levels was found with log-CRP levels, heart attack familial history, and waist circumference as independent predictors. Ferritin behaves as other cardiovascular markers in terms of prediction of its levels by documented predictors of cardiometabolic disease and related disorders. This is the first report of a relationship between heart attack familial history and ferritin levels. Further research is required to evaluate the mechanism to explain the relationship of central body fat and heart attack familial history with body iron stores values.

This study was performed in order to evaluate the sero-epidemiological status of toxoplasmosis in pregnant Korean women. Among 5,175 sera and 750 amniotic fluid samples obtained from pregnant women, 41 serum samples (0.79%) and 10 (1.33%) amniotic fluid samples tested positive for IgG antibodies by ELISA. Fifty one cases showing a score more than 0.25 on ELISA were tested for PCR reaction against the SAG1 gene. Only one case of the 51 ELISA positive cases exhibited a positive reaction on all tests. This case had a history of acute nephropyelitis during early pregnancy, but fortunately, had delivered a phenotypically healthy baby. In this study, the seroprevalence of toxoplasmosis in pregnant women was found to be comparatively low, consistent with previous reports from Korea. However our trials, performed with a variety of diagnostic tools, were considered to be useful for the precise diagnosis of congenital toxoplasmosis.

Background Metabolic syndrome has been associated with an increased risk of breast cancer; however little is known about the association between metabolic syndrome and percent mammographic density, a strong predictor of breast cancer. Methods We analyzed cross-sectional data from 789 premenopausal and 322 postmenopausal women in the Mexican Teacher's Cohort (ESMaestras). Metabolic syndrome was defined according to the harmonized definition. We measured percent density on mammograms using a computer-assisted thresholding method. Multivariable linear regression was used to estimate the association between density and metabolic syndrome, as well as its components by state (Jalisco, Veracruz) and menopausal status (premenopausal, postmenopausal). Results Among premenopausal women in Jalisco, women with metabolic syndrome had higher percent density compared to those without after adjusting for potential confounders including BMI (difference = 4.76, 95%CI: 1.72, 7.81). Among the metabolic syndrome components, only low high-density lipoprotein levels (<50mg/dl) were associated with significantly higher percent density among premenopausal women in Jalisco (difference=4.62, 95%CI: 1.73, 7.52). Metabolic syndrome was not associated with percent density among premenopausal women in Veracruz (difference=-2.91, 95% CI: -7.19, 1.38), nor among postmenopausal women in either state. Conclusion Metabolic syndrome was associated with higher percent density among premenopausal women in Jalisco, Mexico, but was not associated with percent density among premenopausal women in Veracruz, Mexico or among postmenopausal women in either Jalisco or Veracruz. These findings provide some support for a possible role of metabolic syndrome in mammographic density among premenopausal women; however results were inconsistent across states and require further confirmation in larger studies.

Hypertension and hypertriglycemia are the most important contributors to metabolic syndrome (MetS) and cardiovascular disease risk in South Koreans with a relatively lean body mass. These major contributors differ from those identified in Western populations. This study aimed to identify the characteristics of the Korean diet associated with increased risk of MetS, whose prevalence has been steadily increasing in South Korea. On the basis of data collected from 5,320 subjects by the 2007-2008 Korean National Health and Nutrition Examination Survey, 3 dietary patterns were identified using factor analysis and their association with the risk of MetS and its components was examined. The balanced Korean diet, a typical Korean diet of rice and kimchi intake supplemented by a variety of foods had a desirable macronutrient composition and was associated with a lower risk of elevated blood pressure (OR=0.61, 95% CI=0.45-0.84) and hypertriglyceridemia (0.69, 0.49-0.88) in men and a lower risk of elevated blood pressure (0.59, 0.41-0.85) and MetS (0.67, 0.47-0.96) in women. The unbalanced Korean diet, characterized by a high intake of carbohydrates and sodium and little variety, was associated with a higher risk of MetS (1.44, 1.03-2.01) and elevated blood pressure (1.41, 1.00-1.98) in women. The semi-western diet, characterized by a relatively high intake of meat, poultry, and alcohol, was associated with a lower risk of low high-density lipoprotein cholesterol (0.70, 0.54-0.89) in women. Thus, macronutrient composition and sodium intake are associated with the risk of MetS and prehypertension in women. Maintaining a desirable macronutrient composition and avoiding excessive consumption of carbohydrates and sodium should be emphasized for prevention of MetS and hypertension in South Korean women.

Maternal thyroid dysfunction during pregnancy has been associated with adverse outcomes for both the mother and child. For this reason, it is important to understand thyroid status in pregnant women. However, there are relatively few published studies that examine thyroid function tests (TFT) and thyroid autoimmunity in non-Western pregnant women. Serum samples were longitudinally collected throughout pregnancy from 108 Korean women. TFT, thyroid peroxidase antibodies (TPO-Ab), and thyroglobulin antibodies (Tg-Ab) testing was performed. The impact of gestational age on TPO-Ab and Tg-Ab levels was evaluated and gestational age-specific reference intervals for TFT were established in antibody negative women. In the first trimester, TPO-Ab and Tg-Ab were positive in 13.9% and 16.7% of women, respectively. For antibody positive women, median autoantibody levels for TPO-Ab and Tg-Ab dropped from first trimester to near term (133.7-10.5 IU/mL, and 162.1-21.9 IU/mL, respectively). Antibody status influenced thyroid stimulating hormone (TSH) during the first trimester, and TSH, free T4 (FT4) and total T4 (TT4) in the early second trimester. Later in gestation, no significant differences in TFT were found based on antibody status. Gestational age-specific reference intervals for TFT were calculated in antibody negative women. Laboratory evidence of autoimmune thyroid disease (AITD) is common in this population of pregnant Korean women. Antibody status influences TFT values in the first and early second trimester. Thyroid autoantibody status and titer change in an individual-specific manner throughout pregnancy. Gestational age-specific reference intervals should be utilized for interpretation of TFT results in pregnant women.

The 2009 Institute of Medicine (IOM) guidelines for gestational weight gain (GWG) are intended for use among women in the United States. Little data are available on whether the 2009 IOM recommendations can be applied to Asian women. This study aimed to evaluate whether the recommendations are related to adverse pregnancy outcomes in Korean pregnant women. A retrospective cohort study was conducted for all singleton-pregnant women at a university hospital in Korea. After classifying the enrolled women into four Korean pre-pregnancy body mass index (BMI) categories, the risk of adverse pregnancy outcomes were analyzed for women who gained inadequate or excessive GWG based on 2009 IOM recommendations. Of 7,843 pregnancies, 64.0% of women had normal pre-pregnancy BMI and 42.7% achieved optimal GWG. Across all BMI categories, adverse pregnancies outcomes such as small for gestational age (SGA), large for gestational age (LGA), preterm birth, preeclampsia, and cesarean due to dystocia were significantly associated with GWG (all P ≤ 0.001).Women with normal BMI who gained inadequate weight were more likely to develop SGA and preterm birth and less likely to develop LGA (adjusted odds ratio (aOR) 2.21, 1.33, and 0.54, respectively). Whereas, women with normal BMI who gained excessive weight were more likely to develop LGA, preterm birth, preeclampsia, and cesarean section due to dystocia (aOR 2.10, 1.33, 1.37, and 1.37, respectively) and less likely to develop SGA (aOR 0.60). It is tolerable for Korean women to follow recommended GWG from the 2009 IOM guidelines to decrease adverse pregnancy outcomes. This will be helpful for antenatal care on GWG not only for Korean pregnant women, but also other Asian women who have lower BMI criteria than Caucasian women.

Background Soy consumption may protect against breast cancer through modification of estrogen metabolism. Objective We examined the effect of soy foods on urinary estrogens and the 2-hydroxy (OH)/16α-OH estrone (E1) ratio in 2 dietary interventions with premenopausal women. Methods BEAN1 was a 2-year randomized trial and BEAN2 a 13-month randomized crossover study. In both interventions, study participants consumed a high-soy diet with 2 soy food servings/day and a low-soy diet with <3 servings of soy/week. Urine samples were collected at baseline and at the end of the diet periods, analyzed for 9 estrogen metabolites by liquid chromatography mass spectrometry, and adjusted for creatinine levels. For BEAN1, 2 samples for 188 participants and for BEAN2, 3 samples for 79 women were analyzed. We applied mixed-effects regression models with log-transformed values of estrogen metabolites and soy intake as the exposure variable. Results In BEAN1, no effect of the high-soy diet on individual estrogen metabolites or hydroxylation pathways was observed. The median 2-OH/16α-OH E1 ratio decreased non-significantly in the intervention group from 6.2 to 5.2 as compared to 6.8 and 7.2 in the control group (p=0.63). In BEAN2, only 4-OHE1 was significantly lower after the high-soy diet. Interaction terms of the high-soy diet with equol producer status, ethnicity, and weight status revealed no significant effect modification. Conclusions Contrary to our hypothesis and some previous reports, the results from 2 well controlled dietary interventions do not support an effect of a high-soy diet on a panel of urinary estrogen metabolites and the 2-OH/16α-OHE1 ratio.

Caffeinated beverages are widely consumed among women of reproductive age, but their association with reproductive hormones, and whether race modifies any such associations, is not well understood. We assessed the relation between caffeine and caffeinated beverage intake and reproductive hormones in healthy premenopausal women and evaluated the potential effect modification by race. Participants (n = 259) were followed for up to 2 menstrual cycles and provided fasting blood specimens for hormonal assessment at up to 8 visits per cycle and four 24-h dietary recalls per cycle. Weighted linear mixed models and nonlinear mixed models with harmonic terms were used to estimate associations between caffeine and hormone concentrations, adjusted for age, adiposity, physical activity, energy and alcohol intakes, and perceived stress. On the basis of a priori assumptions, an interaction between race and caffeine was tested, and stratified results are presented. Caffeine intake ≥200 mg/d was inversely associated with free estradiol concentrations among white women (β = -0.15; 95% CI: -0.26, -0.05) and positively associated among Asian women (β = 0.61; 95% CI: 0.31, 0.92). Caffeinated soda intake and green tea intake ≥1 cup/d (1 cup = 240 mL) were positively associated with free estradiol concentrations among all races: β = 0.14 (95% CI: 0.06, 0.22) and β = 0.26 (95% CI: 0.07, 0.45), respectively. Moderate consumption of caffeine was associated with reduced estradiol concentrations among white women, whereas caffeinated soda and green tea intakes were associated with increased estradiol concentrations among all races. Further research is warranted on the association between caffeine and caffeinated beverages and reproductive hormones and whether these relations differ by race.

Genes are important BMD determinants. We studied the association of an ESRRA gene functional variant with BMD in 1335 premenopausal women. The ESRRA genotype was an independent predictor of L2-L4 BMD, with an effect similar to smoking and equivalent to a 10-kg difference in weight. Several genetic polymorphisms have been associated with osteoporosis or osteoporosis fractures, but no functional effect has been shown for most of these gene variants. Because functional studies have implicated estrogen-related receptor alpha (ESRRA) in bone metabolism, we evaluated whether a recently described regulatory variant of the ESRRA gene is associated with lumbar and hip BMD as measured by DXA and with heel bone parameters as measured by quantitative ultrasound (QUS). Heel bone parameters were measured by right calcaneal QUS in 1335 healthy French-Canadian premenopausal women, and one-half of these women also had their BMD evaluated at two sites: femoral neck and lumbar spine (L2-L4) by DXA. All bone measures were tested separately for association with the ESRRA genotype by analysis of covariance. The significance of the ESRRA contribution to the model was also assessed by two different permutation tests. A statistically significant association between ESRRA genotype and lumbar spine BMD was observed: women carrying the long ESRRA genotype had a 3.9% (0.045 g/cm2) higher lumbar spine BMD than those carrying the short ESRRA genotype (p = 0.004), independently of other risk factors measured. This effect of ESRRA genotype is similar to the effect of smoking and equivalent to a 10-kg difference in weight. This association was confirmed by permutation tests (p = 0.004). The same trend was observed for femoral neck BMD (2.6%, p = 0.07). However, no association was observed between ESRRA and QUS heel bone measures. These results support the genetic influence of this ESRRA regulatory variant on BMD.

While there is increasing interest in studying aspects of communication processes in sex research, the association between dyadic sexual communication and relationship and sexuality outcomes has not yet been examined in pre-menopausal women with dyspareunia. To examine the associations between dyadic sexual communication and pain, sexual distress, sexual function and dyadic adjustment in women with self-reported dyspareunia and their male partners. Pre-menopausal women (n=38; M age=24.92, SD=6.12) with self-reported dyspareunia from a community sample and their partners (n=38; M age=26.71, SD=6.59) completed an online survey. The Actor-Partner Interdependence Model was used in order to investigate both actor and partner effects. Both members of the couple completed: (i) the Dyadic Sexual Communication Scale and (ii) the Dyadic Adjustment Scale; women also completed (iii) the Female Sexual Function Index, (iv) the Female Sexual Distress Scale, and (v) a Visual Analogue Scale on pain during intercourse; and men also completed (vi) the International Index of Erectile Functioning. Controlling for relationship duration, women's better dyadic sexual communication was significantly associated with their higher levels of sexual function (P=0.028), lower levels of sexual distress (P=0.003) and higher levels of dyadic adjustment (P=0.005), but not with their pain or men's sexual function or dyadic adjustment. Controlling for relationship duration, men's better dyadic sexual communication was associated with their higher levels of dyadic adjustment (P=0.027) but not with their sexual function, nor with women's sexual function or dyadic adjustment. These findings contribute to the theoretical knowledge on interaction processes in couples with dyspareunia and suggest that it may be important to enhance open and direct communication about sexual matters in couples with dyspareunia. © 2014 International Society for Sexual Medicine.

Differential genetic basis for pre-menopausal and post-menopausal salt-sensitive hypertension.

Essential hypertension affects 75% of post-menopausal women in the United States causing greater cardiovascular complications compared with age-matched men and pre-menopausal women. Hormone replacement and current anti-hypertensive therapies do not correct this post-menopausal increased risk suggesting a distinct pathogenic framework. We investigated the hypothesis that distinct genetic determinants might underlie susceptibility to salt sensitive hypertension in pre-menopausal and post-menopausal states. To determine whether distinct genetic loci contribute to post-menopausal salt-sensitive hypertension, we performed a genome-wide scan for quantitative trait loci (QTLs) affecting blood pressure (BP) in 16-month old post-menopausal F2 (Dahl S×R)-intercross female rats characterized for blood pressure by radiotelemetry. Given identical environments and high salt challenge, post-menopausal BP levels were significantly higher than observed in pre-menopausal (post-menopausal versus pre-menopausal SBP, P<0.0001) and ovariectomized (post-menopausal versus ovariectomized SBP, P<0.001) F2-intercross female rats. We detected four significant to highly significant BP-QTLs (BP-pm1 on chromosome 13, LOD 3.78; BP-pm2 on chromosome 11, LOD 2.76; BP-pm3 on chromosome 2, LOD 2.61; BP-pm4 on chromosome 4, LOD 2.50) and two suggestive BP-QTLs (BP-pm5 on chromosome 15, LOD 2.37; BP-f1 on chromosome 5, LOD 1.65), four of which (BP-pm2, BP-pm3, BP-pm4, BP-pm5) were unique to this post-menopausal cohort. These data demonstrate distinct polygenic susceptibility underlying post-menopausal salt-sensitive hypertension providing a pathway towards the identification of mechanism-based therapy for post-menopausal hypertension and ensuing target-organ complications.

Hormonal status influences haemostatic factors including fibrinogen, factor VII and plasminogen activator inhibitor (PAI-1), and concentrations differ among men, premenopausal and postmenopausal women. This study examines how phases of the menstrual cycle influence variability of fibrinogen, factor VII and PAI-1. We studied 103 subjects (39 premenopausal women, 18 postmenopausal women and 46 men) during three, randomized, 8-week energy- and nutrient-controlled experimental diets in the Dietary Effects on Lipids and Thrombogenic Activity (DELTA) Study. Fasting blood samples were collected weekly during the last 4 weeks of each diet period, and haemostatic factors were quantified. Two linear mixed-effects models were used for fibrinogen, factor VII and PAI-1: one to estimate and compare group-specific components of variance, and the other to estimate additional fixed effects representing cyclical functions of day of menstrual cycle in premenopausal women. Systematic cyclical variation with day of menstrual cycle was observed for fibrinogen (P < 0.0001), factor VII (P = 0.0012) and PAI-1 (P = 0.0024) in premenopausal women. However, the amplitude of cycling was small relative to the total magnitude of intra-individual variability. In addition, the intra-individual variance and corresponding coefficient of variation observed in premenopausal women did not differ from postmenopausal women and men. The variability in haemostatic factors in premenopausal women is no greater than for postmenopausal women or men. Consequently, premenopausal women can be included in studies investigating haemostatic factor responses without controlling for stage of menstrual cycle. © 2014 Stichting European Society for Clinical Investigation Journal Foundation.

To identify the independently associating factors on physical inactivity in Korean men and women. The data of 5554 men and women (18-74 years) were analyzed using national health and nutritional examination survey data that included questionnaires and physical examinations. Multiple logistic regression analyses showed that significant factors were low monthly income, low education, current smoking, increased waist-to-hip ratio, and low health concern among men; living in rural areas, low monthly income, low education, perceived poor health status, low health concern, and emotional stress among women. Health care providers should focus on education and counseling regarding the factors that influence physical inactivity.

The term hwa-byung (HB) as a culture-bound syndrome of Koreans has been used to refer to certain types of symptom complexes. However, there is an ambiguity in relation to what sorts of experiences and personal attributes can be identified for describing HB. Our study was designed to reexamine the conceptual structure of HB through a qualitative analysis of interview data with six middle-aged women experiencing HB. The emerging common themes of HB were identified in three dimensions: (a) those related to personal attributes or life situations such as quick-temperedness, strong commitment to traditional values, a hard or unhappy life, and conflicted marital relationship; (b) those related to experiential accounts such as deep sorrow (hahn in Korean), a feeling of victimization, anger, and enduring; and (c) HB symptoms. "Enduring" as one of the core concepts of HB viewed as the only way of life for these women needs further examination.

Background Urinary tract infections (UTIs) are common and result in an enormous economic burden. The increasing prevalence of antibiotic-resistant microorganisms has stimulated interest in non-antibiotic agents to prevent UTIs. Objective To evaluate the cost-effectiveness of cranberry prophylaxis compared to antibiotic prophylaxis with trimethoprim-sulfamethoxazole (TMP-SMX) over a 12 month period in premenopausal women with recurrent UTIs. Materials and Methods An economic evaluation was performed alongside a randomized trial. Primary outcome was the number of UTIs during 12 months. Secondary outcomes included satisfaction and quality of life. Healthcare utilization was measured using questionnaires. Missing data were imputed using multiple imputation. Bootstrapping was used to evaluate the cost-effectiveness of the treatments. Results Cranberry prophylaxis was less effective than TMP-SMX prophylaxis, but the differences in clinical outcomes were not statistically significant. Costs after 12 months in the cranberry group were statistically significantly higher than in the TMP-SMX group (mean difference €249, 95% confidence interval 70 to 516). Cost-effectiveness planes and cost-effectiveness acceptability curves showed that cranberry prophylaxis to prevent UTIs is less effective and more expensive than (dominated by) TMP-SMX prophylaxis. Conclusion In premenopausal women with recurrent UTIs, cranberry prophylaxis is not cost-effective compared to TMP-SMX prophylaxis. However, it was not possible to take into account costs attributed to increased antibiotic resistance within the framework of this randomized trial; modeling studies are recommended to investigate these costs. Moreover, although we based the dosage of cranberry extract on available evidence, this may not be the optimal dosage. Results may change when this optimal dosage is identified.

An increased prevalence of female sexual dysfunction (FSD) has been reported in women with diabetes mellitus (DM). Our aim was to evaluate correlates (psychological, cardiovascular, and neurophysiologic) of FSD in DM women without chronic diabetic complications. Female Sexual Function Index (FSFI), Beck Depression Inventory (BDI), Michigan Diabetic Neuropathy Index (DNI), and the symptoms of diabetic neuropathy (SDN) questionnaires, metabolic variables, endothelial vascular function (flow-mediated dilation, FMD), echocardiography, and electromyography were studied. 109 pre-menopausal women (18-50 years) [48 with DM (14 type 1 DM, 34 type 2 DM, duration 12.6 ± 1.91 years), and 61 healthy women] received the above questionnaires; physical activity, smoking habits, parity, BMI, waist circumference, HOMA-IR index, fibrinogen, cholesterol (total, HDL, LDL), triglycerides, HbA1c, high-sensitivity C-reactive protein, total testosterone, and estradiol were measured; echocardiography, assessment of intima-media thickness (IMT), FMD, ECG (heart rate and Qtc, indexes of sympathetic activity), and electromyography were performed. FSFI total score and score for arousal, lubrication, and orgasm domains were lower in DM women than in controls (P < 0.05); DM women had higher BDI, Doppler A wave peak velocity, DNI, and SDN score (P < 0.001 to P < 0.04). Doppler E wave peak velocity, peroneal, posterior tibial and sural nerves conduction velocity and amplitude were lower in diabetic women than in controls (P < 0.05 to P < 0.001). FSFI score was positively correlated with physical activity, Doppler E wave peak velocity, and peroneal nerve amplitude and negatively with BDI, parity, IMT, SDN, and HbA1c (P < 0.05 to P < 0.001). At stepwise regression, SDN score (negatively) and Doppler E wave peak velocity (positively) predicted FSFI score (r = 507, P < 0.001). In conclusion, cardiovascular and neurological impairments are associated with FSD in diabetic women. Follow-up studies are

We examined the relationship between low bond mass and metabolic syndrome in 2,475 Korean women. After adjustment for all covariates, mean vertebral BMD was significantly lower in women with metabolic syndrome. Moreover, age and weight adjusted vertebral BMD was significantly decreased with additional components of the metabolic syndrome. Obesity-induced chronic inflammation is a key component in the pathogenesis of insulin resistance and metabolic syndrome. It has been suggested that proinflammatory cytokines and low-grade systemic inflammation activate bone resorption and may lead to reduced bone mineral density (BMD). The objective of this study was to determine the relationship between low bone mass and metabolic syndrome in Korean women. This is a cross-sectional study of 2,548 women aged 18 years and over who had visited the Health Promotion Center. Physical examination and laboratory tests were performed. Vertebral BMD was measured using dual-energy X-ray absorptiometry. Metabolic syndrome was defined by National Cholesterol Education Program-Adult Treatment Panel III criteria. Among 2,475 women, 511 (21.0%) women had metabolic syndrome. Women with abdominal obesity or hypertriglyceridemia had significantly lower vertebral BMD than women without respective components after adjustment for age, weight, and height. After adjustment for all covariates, mean vertebral BMD was significantly lower in women with metabolic syndrome (p = 0.031). Moreover, age- and weight-adjusted vertebral BMD were significantly decreased with additional components of the metabolic syndrome (p = 0.004). These findings suggest that metabolic syndrome might be another risk factor for osteoporosis and related fractures.

We performed a multicenter cross-sectional study of 134 sexually active systemic lupus erythematosus (SLE) patients to investigate the prevalence of and risk factors for high risk human papilloma virus (HPV) infection and cervical cytological abnormalities among Korean women with SLE. In this multicenter cross-sectional study, HPV testing and routine cervical cytologic examination was performed. HPV was typed using a hybrid method or the polymerase chain reaction. Data on 4,595 healthy women were used for comparison. SLE patients had greater prevalence of high-risk HPV infection (24.6% vs. 7.9%, P<0.001, odds ratio 3.8, 95% confidence interval 2.5-5.7) and of abnormal cervical cytology (16.4 vs. 2.8%, P<0.001, OR 4.4, 95% CI 2.5-7.8) compared with controls. SLE itself was identified as independent risk factors for high risk HPV infection among Korean women (OR 3.8, 95% CI 2.5-5.7) along with ≥2 sexual partners (OR 8.5, 95% CI 1.2-61.6), and Pap smear abnormalities (OR 97.3, 95% CI 6.5-1,456.7). High-risk HPV infection and cervical cytological abnormalities were more common among Korean women with SLE than controls. SLE itself may be a risk factor for HPV infection among Korean women, suggesting the importance of close monitoring of HPV infections and abnormal Pap smears in SLE patients.

Prior research supports an association between endogenous sex steroids and breast cancer among postmenopausal women; the association is less clear among premenopausal women. We evaluated the associations between estrogens, androgens, progesterone and sex hormone binding globulin (SHBG) and breast cancer in a nested case-control study in the Nurses' Health Study II. Between 1996 and 1999, 29,611 participants provided blood samples; 18,521 provided samples timed in early follicular and mid-luteal phases of the menstrual cycle. A total of 634 women, premenopausal at blood collection, developed breast cancer between 1999 and 2009 and were matched to 1,264 controls (514 cases and 1,030 controls with timed samples). We used conditional logistic regression controlling for breast cancer risk factors for overall analyses; unconditional logistic regression additionally controlling for matching factors was used for subgroup analyses. In analyses of premenopausal estrogens including breast cancers diagnosed both before and after menopause, there was no association between follicular estradiol, estrone and free estradiol and risk of either total or invasive breast cancer. Luteal estradiol was positively associated with estrogen receptor positive (ER+)/progesterone receptor positive (PR+) cancers (5th vs. 1st quintile odds ratio (OR): 1.7 (95% confidence interval (CI): 1.0 to 2.9), Ptrend = 0.02). Luteal estrone, free estradiol and progesterone were not associated with risk. Androgens were suggestively or significantly associated with risk when the sample was restricted to invasive tumors (for example, testosterone: OR: 1.4 (1.0 to 2.0), Ptrend = 0.23) and ER+/PR+ disease (testosterone: OR: 1.7 (1.1 to 2.6) Ptrend = 0.10; dehydroepiandrosterone sulfate (DHEAS) OR: 1.3 (0.8 to 2.0) Ptrend = 0.05). SHBG was not associated with breast cancer risk. The results varied by menopausal status at diagnosis, with follicular estradiol suggestively positively associated with breast cancers

To test a hypothetical model of depression in Korean women with breast cancer and to test the mediating effects of self-esteem and hope. Cross-sectional design. Participants were recruited from three general hospitals and one cancer hospital in Busan, South Korea. 214 Korean women diagnosed with breast cancer (stages I-III). All participants completed questionnaires (e.g., Zung Self-Rating Depression scale, Herth Hope Scale, Rosenberg Self-Esteem Scale, Health Self-Rating Scale in Health and Activity survey, Kang's Family Support Scale). Based on the literature, Mplus, version 3.0, was used to determine the best depression model with path analysis. Depression, self-esteem, hope, perceived health status, religious beliefs, family support, economic status, and fatigue. Self-esteem was directly affected by perceived health status, religious beliefs, family support, economic status, and fatigue. Hope was directly affected by family support, self-esteem, and how patients perceived their health status. Depression was directly affected by self-esteem and hope. The path analysis model explained 31% of the variance in depression in Korean women with breast cancer. A model of depression in Korean women with breast cancer was developed, and self-esteem and hope were mediating factors of depression. Self-esteem and hope must be considered when developing services to reduce depression in Korean women with breast cancer.

This study investigated whether polymorphisms within the Fanconi anemia complementation group A (FANCA) gene contribute to the increased risk of premature ovarian failure (POF) in Korean women. Ninety-eight women with POF and 218 controls participated in this study. Genomic DNA from peripheral blood was isolated, and GoldenGate genotyping assay was used to identify single nucleotide polymorphisms (SNPs) within the FANCA gene. Two significant SNPs (rs1006547 and rs2239359; P < 0.05) were identified by logistic regression analysis, but results were insignificant after Bonferroni correction. Six SNPs formed a linkage disequilibrium block, and three main haplotypes were found. Two of three haplotypes (AAAGAA and GGGAGG) distributed highly in the POF group, whereas the remaining haplotype (GGAAGG) distributed highly in the control group by logistic regression analysis (highest odds ratio, 2.515; 95% CI, 1.515-4.175; P = 0.00036). Our observations suggest that genetic variations in the FANCA gene may increase the risk for POF in Korean women.

Abdominal adiposity is associated with low BMD and decreased growth hormone (GH) secretion, an important regulator of bone homeostasis. The purpose of our study was to determine the effects of a short course of GH on markers of bone turnover and bone marrow fat in premenopausal women with abdominal adiposity. In a 6-month, randomized, double-blind, placebo-controlled trial we studied 79 abdominally obese premenopausal women (21-45 y) who underwent daily sc injections of GH vs. placebo. Main outcome measures were body composition by DXA and CT, bone marrow fat by proton MR spectroscopy, P1NP, CTX, 25(OH)D, hsCRP, undercarboxylated osteocalcin (ucOC), preadipocyte factor 1 (Pref 1), apolipoprotein B (ApoB), and IGF-1. GH increased IGF-1, P1NP, 25(OH)D, ucOC, bone marrow fat and lean mass, and decreased abdominal fat, hsCRP, and ApoB compared with placebo (p<0.05). There was a trend toward an increase in CTX and Pref-1. Among all participants, a 6-month increase in IGF-1 correlated with 6-month increase in P1NP (p=0.0005), suggesting that subjects with the greatest increases in IGF-1 experienced the greatest increases in bone formation. A six-month decrease in abdominal fat, hsCRP, and ApoB inversely predicted 6-month change in P1NP, and 6-month increase in lean mass and 25(OH)D positively predicted 6-month change in P1NP (p≤0.05), suggesting that subjects with greatest decreases in abdominal fat, inflammation and ApoB, and the greatest increases in lean mass and 25(OH)D experienced the greatest increases in bone formation. A six-month increase in bone marrow fat correlated with 6-month increase in P1NP (trend), suggesting that subjects with the greatest increases in bone formation experienced the greatest increases in bone marrow fat. Forward stepwise regression analysis indicated that increase in lean mass and decrease in abdominal fat were positive predictors of P1NP. When IGF-1 was added to the model, it became the only predictor of P1NP. GH replacement in

Besides its classical role in musculoskeletal diseases, vitamin D deficiency has recently been found to be associated with cardiometabolic risks such as hypertension, diabetes mellitus and hypercholesterolemia. Although Malaysia is a sunshine-abundant country, recent studies found that vitamin D deficiency prevalence was significantly high. However, few published studies that measured its effect on cardiometabolic risk factors were found in Malaysia. There are also limited clinical trials carried out globally that tried to establish the causality of vitamin D and cardiometabolic risks. Therefore, a double blind, parallel, randomized controlled trial on vitamin D and cardiometabolic risks is planned to be carried out.The objective of this study is to investigate whether vitamin D supplements can reduce the cardiometabolic risk and improve the quality of life in urban premenopausal women with vitamin D deficiency. Three hundred and twenty premenopausal women working in a public university in Kuala Lumpur, Malaysia will be randomized to receive either vitamin D supplement (50,000 IU weekly for 8 weeks and 50,000 IU monthly for 10 months) or placebo for 12 months. At baseline, all participants are vitamin D deficient (≤ 20 ng/ml or 50 nmol/l). Both participants and researchers will be blinded. The serum vitamin D levels of all participants collected at various time points will only be analysed at the end of the trial. Outcome measures such as 25(OH) D3, HOMA-IR, blood pressure, full lipid profiles will be taken at baseline, 6 months and 12 months. Health related quality of life will be measured at baseline and 12 months. The placebo group will be given delayed treatment for six months after the trial. This trial will be the first study investigating the effect of vitamin D supplements on both the cardiometabolic risk and quality of life among urban premenopausal women in Malaysia. Our findings will contribute to the growing body of knowledge in the role of vitamin D

In this cross-sectional study based on Korean elderly men and women, heavy alcohol intake for men was related to low whole-body BMD and light alcohol intake for women was associated with high whole-body, lumbar, and total femur BMD. Alcohol is a risk factor of osteoporosis but previous studies on its effect on bone health has been controversial. The aim of this study was to evaluate the association between alcohol intake and bone mineral density in Korean elderly men and women. Based on the Fourth and Fifth Korean National Health and Nutrition Examination Surveys (KNHANES), 2657 men and 2080 women 50 to 79 years of age were included. Bone mineral density (BMD) was measured using dual energy X-ray absorptiometry (DXA). Alcohol consumption was determined by self-administered questionnaires and classified into four groups according to sex: non-drinkers (0 g/day), light drinking (1-19 g/day men, 1-9 g/day women), moderate drinking (20-39 g/day men, 10-29 g/day women), and heavy drinking (≥ 40 g/day men, ≥ 20 g/day women). The adjusted mean values calculated by linear regression analysis for BMD were determined according to the amount of alcohol consumed. Light drinkers had the highest whole-body BMD for both men (mean 1.164, SD 0.047-1.281) and women (mean 1.046, SD 0.912-1.180). Among men, mean whole-body BMD for heavy drinkers was significantly lower than that among light drinkers (P = 0.031). Among women, BMD for light drinkers was significantly higher in the whole body, lumbar, and total femur than that for non-drinkers (P < 0.001, P = 0.026, P = 0.040, respectively). Heavy alcohol intake may be associated with lower BMD in men while light alcohol intake may associate with higher BMD among women. Future longitudinal studies investigating the effect of alcohol consumption on bone mineral density are needed to validate the findings of this study.

The impact of perceived childhood victimization and patriarchal gender ideology on intimate partner violence (IPV) victimization among Korean immigrant women in the USA.

Childhood victimization experiences are common among intimate partner violence (IPV) victims. This study examines the link between childhood physical and sexual victimization experiences and adulthood IPV among Korean immigrant women in the USA. As Korean immigrants often use physical punishment to discipline their children, and reporting sexual abuse is discouraged due to stigmatization in this community, cultural factors (e.g. patriarchal values) related to childhood victimization and IPV were also examined. Survey data from Korean immigrant women in the USA were collected. Using a case-control design, we compared 64 Korean immigrant women who have experienced IPV in the past year with 63 Korean immigrant women who have never experienced IPV in their lifetime. The findings of this study reveal that IPV victims, compared with non-victims, experienced higher childhood victimization rates. Logistic regression analysis demonstrated that childhood victimization and patriarchal gender ideology strongly predict IPV victimization among Korean immigrants. However, patriarchal values did not moderate the relationship between childhood victimization and IPV. To prevent IPV among Korean immigrant population, we need to make special efforts to prevent childhood abuse and change ingrained cultural attitudes about child physical and sexual abuse among immigrant communities through culturally sensitive programs.

To investigate the predominant Lactobacillus species types (LSTs) of vaginal microbiota in pregnant Korean women by quantifying five Lactobacillus species and two anaerobes. In all, 168 pregnant Korean women under antenatal care at Eulji University Hospital and local clinics were enrolled in the prospective cohort study during pregnancy (10-14 weeks). Vaginal samples were collected with Eswab for Quantitative polymerase chain reaction (qPCR) and stored in a -80 °C freezer. qPCR was performed for five Lactobacillus species and two anaerobes. To identify the predominant LSTs, quantifications were analyzed by the Cluster and Tree View programs of Eisen Lab. Also the quantifications were compared among classified groups. L. crispatus and L. iners were most commonly found in pregnant Korean women, followed by L. gasseri and L. jensenii; L. vaginalis was nearly absent. Five types (four predominant LSTs and one predominant anaerobe type without predominant Lactobacillus species) were classified. Five predominant LSTs were identified in vaginal microbiota of pregnant Korean women. L. crispatus and L. iners predominant types comprised a large proportion.

Purpose This study investigates Korean speech sound development, including articulatory error patterns, among the Japanese-Korean children whose mothers are Japanese immigrants to Korea. Methods The subjects were 28 Japanese-Korean children with normal development born to Japanese women immigrants who lived in Jeonbuk province, Korea. They were assessed through Computerized Speech Lab 4500. The control group consisted of 15 Korean children who lived in the same area. Results The values of the voice onset time of consonants /ph/, /t/, /th/, and /k*/ among the children were prolonged. The children replaced the lenis sounds with aspirated or fortis sounds rather than replacing the fortis sounds with lenis or aspirated sounds, which are typical among Japanese immigrants. The children showed numerous articulatory errors for /c/ and /l/ sounds (similar to Koreans) rather than errors on /p/ sounds, which are more frequent among Japanese immigrants. The vowel formants of the children showed a significantly prolonged vowel /o/ as compared to that of Korean children (P<0.05). The Japanese immigrants and their children showed a similar substitution /n/ for /ɧ/ [Japanese immigrants (62.5%) vs Japanese-Korean children (14.3%)], which is rarely seen among Koreans. Conclusion The findings suggest that Korean speech sound development among Japanese-Korean children is influenced not only by the Korean language environment but also by their maternal language. Therefore, appropriate language education programs may be warranted not only or immigrant women but also for their children. PMID:21189968

Opiate changes have been reported in response to excessive alcohol consumption. Different phases of the menstrual cycle also affect the opiate tone. The authors studied the effect of moderate alcohol consumption and the menstrual cycle per se on plasma opiates. Forty premenopausal women were given alcohol or a soft drink of equal caloric value for 3 menstrual cycles in a cross over study. The subjects were fed a controlled diet containing 35% of energy from fat. Blood was collected in the third menstrual cycle of each period during follicular (F), ovulatory (O) and luteal (L) phases. {beta}-endorphin, met-enkephalin and lwu-enkephalinmore » (LE) were measured by radioimmunoassay. None of the opiates showed significant change after alcohol consumption though LE was consistently higher after alcohol consumption during all three phases of the menstrual cycle. There was a significant decrease in BEN during L phase compared to F phase while both enkephalins were higher during L phase than during F phase. Opiate levels during O phase were intermediate between F and L. Thus, in contrast to previously observed opiate changes following excessive alcohol consumption, they did not observe changes with moderate consumption.« less

Essential hypertension affects 75% of post-menopausal women in the United States causing greater cardiovascular complications compared with age-matched men and pre-menopausal women. Hormone replacement and current anti-hypertensive therapies do not correct this post-menopausal increased risk suggesting a distinct pathogenic framework. We investigated the hypothesis that distinct genetic determinants might underlie susceptibility to salt sensitive hypertension in pre-menopausal and post-menopausal states. To determine whether distinct genetic loci contribute to post-menopausal salt-sensitive hypertension, we performed a genome-wide scan for quantitative trait loci (QTLs) affecting blood pressure (BP) in 16-month old post-menopausal F2 (Dahl S×R)-intercross female rats characterized for blood pressure by radiotelemetry. Given identical environments and high salt challenge, post-menopausal BP levels were significantly higher than observed in pre-menopausal (post-menopausal versus pre-menopausal SBP, P<0.0001) and ovariectomized (post-menopausal versus ovariectomized SBP, P<0.001) F2-intercross female rats. We detected four significant to highly significant BP-QTLs (BP-pm1 on chromosome 13, LOD 3.78; BP-pm2 on chromosome 11, LOD 2.76; BP-pm3 on chromosome 2, LOD 2.61; BP-pm4 on chromosome 4, LOD 2.50) and two suggestive BP-QTLs (BP-pm5 on chromosome 15, LOD 2.37; BP-f1 on chromosome 5, LOD 1.65), four of which (BP-pm2, BP-pm3, BP-pm4, BP-pm5) were unique to this post-menopausal cohort. These data demonstrate distinct polygenic susceptibility underlying post-menopausal salt-sensitive hypertension providing a pathway towards the identification of mechanism-based therapy for post-menopausal hypertension and ensuing target-organ complications.

Assimilation and health service utilization of Korean immigrant women.

2013-11-01

In this case study, I present descriptive findings with regard to immigrant incorporation and health service utilization. Using focus groups and survey of Korean immigrant women in Wisconsin, I examine whether the ways in which they adapt to the U.S. society is relevant to their health services utilization and the alternatives they seek when available health services are less than satisfactory. The findings suggest that adherence to Korean identity appears to be associated with health service utilization. This is evident in the immigrants' evaluation of the U.S. health services as compared to those of Korea, and the consideration given by these immigrants to seeking health services in Korea instead of the United States. Such concerns on the part of these immigrants have important implications for health researchers, as they highlight the significance of immigrants' transnational experiences and their sense of personal agency in the use of health care.

The purpose of this study was to evaluate the ethnic difference in bone mass between Japanese and Inner Mongolian young premenopausal women and to assess the contribution of lifestyle related and anthropometric factors to bone mass. We studied 33 Japanese and 44 Inner Mongolian healthy young women, aged 20-34 years, in urban area. Speed of sound (SOS), broadband ultrasound attenuation (BUA) and stiffness index (SI) were measured at the calcaneus using quantitative ultrasound (QUS) analysis. Age at menarche, regularity of menstruation and lifestyle related factors were estimated by a self-reported questionnaire. There were no differences between the two groups in age, height, weight, BMI, regularity of menstruation, frequency of meat intake, frequency of yellow-green vegetable intake and exercise habit. Japanese women had significantly lower age at menarche and higher proportion of milk consumption habit at junior high school, senior school and present. Before adjustment, Japanese women had significantly higher SOS and SI than Inner Mongolian women. However, after adjustment for age at menarche and milk consumption habit at junior high school, both of which were significantly different between groups, no group-differences remained in either SOS or SI. These results suggest that the differences in age at menarche and milk consumption habit at junior high school, which relate to hormonal and nutritional status during puberty, may account for the differences in bone mass between Japanese and Inner Mongolian young women.

Our prior observations in normotensive postmenopausal women stimulated the hypotheses that compared with eumenorrheic women, active hypoestrogenic premenopausal women with functional hypothalamic amenorrhea would demonstrate attenuated reflex renin-angiotensin-aldosterone system responses to an orthostatic challenge, whereas to defend blood pressure reflex increases in muscle, sympathetic nerve activity would be augmented. To test these hypotheses, we assessed, in recreationally active women, 12 with amenorrhea (ExFHA; aged 25 ± 1 years; body mass index 20.7 ± 0.7 kg/m(2); mean ± SEM) and 17 with eumenorrhea (ExOv; 24 ± 1 years; 20.9 ± 0.5 kg/m(2)), blood pressure, heart rate, plasma renin, angiotensin II, aldosterone, and muscle sympathetic nerve activity at supine rest and during graded lower body negative pressure (-10, -20, and -40 mm Hg). At baseline, heart rate and systolic blood pressure were lower (P<0.05) in ExFHA (47 ± 2 beats/min and 94 ± 2 mm Hg) compared with ExOv (56 ± 2 beats/min and 105 ± 2 mm Hg), but muscle sympathetic nerve activity and renin-angiotensin-aldosterone system constituents were similar (P>0.05). In response to graded lower body negative pressure, heart rate increased (P<0.05) and systolic blood pressure decreased (P<0.05) in both groups, but these remained consistently lower in ExFHA (P<0.05). Lower body negative pressure elicited increases (P<0.05) in renin, angiotensin II, and aldosterone in ExOv, but not in ExFHA (P>0.05). Muscle sympathetic nerve activity burst incidence increased reflexively in both groups, but more so in ExFHA (P<0.05). Otherwise, healthy hypoestrogenic ExFHA women demonstrate low blood pressure and disruption of the normal circulatory response to an orthostatic challenge: plasma renin, angiotensin II, and aldosterone fail to increase and blood pressure is defended by an augmented sympathetic vasoconstrictor response. © 2015 American Heart Association, Inc.

Increased circadian prolactin release is blunted after body weight loss in obese premenopausal women.

We recently showed that prolactin (PRL) release is considerably enhanced in obese women in proportion to the size of their visceral fat mass. PRL release is inhibited by dopamine 2 receptor (D2R) activation, and dietary restriction/weight loss are associated with increased dopaminergic signaling in animals. Therefore, we hypothesized that enhanced PRL release in obese humans would be reversed by weight loss. To evaluate this postulate, we measured 24-h plasma PRL concentrations at 10-min intervals in 11 obese premenopausal women (BMI 33.3 +/- 0.7 kg/m2) before and after weight loss (50% reduction of overweight/15% absolute weight loss, using a very low-calorie diet) in the follicular phase of their menstrual cycle. The 24-h PRL concentration profiles were analyzed by a peak detection program (Cluster) and a wave form-independent deconvolution technique (Pulse). Spontaneous 24-h PRL secretion was significantly reduced in obese women [mean daily release, before 128 +/- 24 vs. after weight loss 110 +/- 17 microg/liter distribution volume (Vdl)(-1) x 24 h, P = 0.05]. Body weight loss particularly blunted PRL secretory burst mass (Pulse area, before 230 +/- 28 vs. after weight loss 221 +/- 31 microg/Vdl(-1) x 24 h, P = 0.03), whereas burst frequency was unaffected (no. of pulses, before 11 +/- 1 vs. after weight loss 12 +/- 1 n/24 h, P = 0.69). Thus elevated PRL secretion rate in obese women is significantly reduced after loss of 50% of overweight. We speculate that amelioration of deficit D2R-mediated neurotransmission and/or diminutions of circulating leptin/estrogen levels might be involved in the physiology of this phenomenon.

This study assessed and compared heath-related behaviours and nutrient and food group intakes between US-born and Korea-born Korean American women. Cross-sectional analyses were performed for ethnic Koreans who participated in the Multiethnic Cohort Study in Hawaii and Los Angeles in 1993-1996. The sample included 492 Korean American women aged 45-75 years who were born in the USA (n = 274) or Korea (n = 218). Participants were recruited using driver's license files as a primary sampling source and completed a self-administered questionnaire, including a quantitative food frequency section. The proportion overweight or obese was 31.4% in US-born and 9.4% in Korea-born women. US-born women had higher intakes of total fat and fat as a percentage of energy, and lower intakes of sodium, vitamin C, beta-carotene and carbohydrate as a percentage of energy, than Korea-born women. Comparing intakes of food group servings from the Food Guide Pyramid, US-born women reported more whole grains, red meat and nuts, and less soy products, than did Korea-born women. US-born women also consumed fewer vegetables and fruit than those born in Korea. Few women in either group reported intakes that met the recommendations for dairy foods. Intake of discretionary fat from the Pyramid tip was higher in US-born than in Korea-born women. These findings indicate that the acculturation of Korean immigrants affects dietary intakes in ways that may alter risks of several chronic diseases. Further studies will be necessary to examine the effects of dietary acculturation on disease patterns.

Patients with active celiac disease (CD) are more likely to have osteoporosis and increased risk of fractures. High-resolution peripheral quantitative computed tomography (HR-pQCT) permits three-dimensional exploration of bone microarchitectural characteristics measuring separately cortical and trabecular compartments, and giving a more profound insight into bone disease pathophysiology and fracture. We aimed to determine the volumetric and microarchitectural characteristics of peripheral bones-distal radius and tibia-in an adult premenopausal cohort with active CD assessed at diagnosis. We prospectively enrolled 31 consecutive premenopausal women with newly diagnosed CD (median age 29 years, range: 18-49) and 22 healthy women of similar age (median age 30 years, range 21-41) and body mass index. Compared with controls, peripheral bones of CD patients were significantly lower in terms of total volumetric density mg/cm(3) (mean ± SD: 274.7 ± 51.7 vs. 324.7 ± 45.8, p 0.0006 at the radius; 264.4 ± 48.7 vs. 307 ± 40.7, p 0.002 at the tibia), trabecular density mg/cm(3) (118.6 ± 31.5 vs. 161.9 ± 33.6, p<0.0001 at the radius; 127.9 ± 28.7 vs. 157.6 ± 15.6, p < 0.0001 at the tibia); bone volume/trabecular volume ratio % (9.9 ± 2.6 vs. 13.5 ± 2.8, p<0.0001 at the radius; 10.6 ± 2.4 vs. 13.1 ± 1.3, p < 0.0001 at the tibia); number of trabeculae 1/mm (1.69 ± 0.27 vs. 1.89 ± 0.26, p 0.009 at the radius; 1.53 ± 0.32 vs. 1.80 ± 0.26, p 0.002 at the tibia); and trabecular thickness mm (0.058 ± 0.010 vs. 0.071 ± 0.008, p < 0.0001 at the radius with no significant difference at the tibia). Cortical density was significantly lower in both regions (D comp mg/cm(3) 860 ± 57.2 vs. 893.9 ± 43, p 0.02; 902.7 ± 48.7 vs. 932.6 ± 32.6, p 0.01 in radius and tibia respectively). Although cortical thickness was lower in CD patients, it failed to show any significant inter-group difference (a-8% decay with p 0.11 in both bones). Patients with symptomatic CD (n = 22) had

To compare the increases in upper- and lower-body muscle strength in premenopausal women performing resistance training (RT) alone or alongside concurrent high-intensity interval training (CT). Sixteen women (26-40 years) were randomly assigned into two groups that performed either RT or CT. Both groups performed the same RT program; however, CT performed additional high-intensity interval training (HIIT) on a bicycle ergometer before RT. The study lasted 8 weeks and the participants were tested for ten repetition maximum (10RM) load in elbow flexion (barbell biceps curl) and knee extension exercises pre- and post-intervention. RT was performed with 10-12 repetitions to self-determined repetition maximum in the first four weeks and then progressed to 8-10. During CT, HIIT was performed before RT with six 1-min bouts at 7-8 of perceived subjective exertion (RPE) and then progressed to eight bouts at 9-10 RPE. Analysis of variance revealed significant increases in upper and lower body strength for both the RT and CT groups. Biceps barbell curl 10RM load increased from 12.9 ± 3.2 kg to 14 ± 1.5 kg in CT (p < 0.05) and from 13 ± 1.8 kg to 15.9 ± 2.5 kg in RT (p < 0.05), with no significant between-groups differences. Knee extension 10RM increase from 31.9 ± 11.6 kg to 37.5 ± 8.5 kg for CT (p < 0.05) and from 30.6 ± 8.6 kg to 41.2 ± 7.4 kg for RT (p < 0.05). In conclusion, performing HIIT on a cycle ergometer before resistance training does not seem to impair muscle strength increases in the knee extensors or elbow flexors of pre-menopausal women. This information should be considered when prescribing exercise sessions, since both activities may be combined without negative effects in muscle strength.

To assess sexually related personal distress among premenopausal women with female sexual dysfunction (FSD) via a validated Arabic version of the Female Sexual Distress Scale (FSDS). A cross-sectional study was conducted among women attending Suez Canal University Hospital, Egypt, between May 2015 and July 2016. In a pilot study to evaluate test-retest reliability and internal consistency, 42 sexually active premenopausal women (aged ≥20 years) completed the Arabic FSDS at recruitment and 2 weeks later. Subsequently, premenopausal sexually active women (aged 20-45 years) were asked to complete the female sexual function index (FSFI) questionnaire; those with FSD (FSFI score ≤26.55) were invited to return to complete the validated version of the Arabic FSDS. The Arabic FSDS showed good test-retest reliability (Pearson correlation coefficient 0.93-0.98) and internal consistency (Cronbach α 0.83-0.92). Overall, 140 (58.1%) of 241 women who completed the FSFI had sexual dysfunction, of whom 51 (36.4%) had sexually related personal distress. Marriage duration was significantly increased among women with FSD (P<0.001). All FSFI sexual domains except lubrication were negatively correlated with FSDS. FSD and sexually related personal distress were highly interrelated and prevalent. An Arabic version of the FSDS was found to be valid and reliable for evaluation of sexually related personal distress. © 2017 International Federation of Gynecology and Obstetrics.

Acrylamide, a probable human carcinogen, is formed during high-temperature cooking of many commonly consumed foods. It is widespread; approximately 30% of calories consumed in the United States are from foods containing acrylamide. In animal studies, acrylamide causes mammary tumors, but it is unknown whether the level of acrylamide in foods affects human breast cancer risk. The authors studied the association between acrylamide intake and breast cancer risk among 90,628 premenopausal women in the Nurses' Health Study II. They calculated acrylamide intake from food frequency questionnaires in 1991, 1995, 1999, and 2003. From 1991 through 2005, they documented 1,179 cases of invasive breast cancer. They used Cox proportional hazards models to assess the association between acrylamide and breast cancer risk. The multivariable-adjusted relative risk of premenopausal breast cancer was 0.92 (95% confidence interval: 0.76, 1.11) for the highest versus the lowest quintile of acrylamide intake (Ptrend = 0.61). Results were similar regardless of smoking status or estrogen and progesterone receptor status of the tumors. The authors found no associations between intakes of foods high in acrylamide, including French fries, coffee, cereal, potato chips, potatoes, and baked goods, and breast cancer risk. They found no evidence that acrylamide intake, within the range of US diets, is associated with increased risk of premenopausal breast cancer. PMID:19224978

The multivariable-adjusted relative risk of premenopausal breast cancer was 0.92 (95% confidence interval: 0.76, 1.11) for the highest versus the lowest quintile of acrylamide intake (P(trend) = 0.61). Results were similar regardless of smoking status or estrogen and progesterone receptor status of the tumors. The authors found no associations between intakes of foods high in acrylamide, including French fries, coffee, cereal, potato chips, potatoes, and baked goods, and breast cancer risk. They found no evidence that acrylamide intake, within the range of US diets, is associated with increased risk of premenopausal breast cancer.

This study examined the effects of 3 days of estrogen supplementation (ES) on thermoregulation during exercise in premenopausal (20-39 yr) adult women during the follicular phase of the menstrual cycle. Subjects (11 control, 10 experimental) performed upright cycle ergometer exercise at 60% of maximal O2 consumption in a neutral environment (25 degreesC, 30% relative humidity) for 20 min. Subjects were given placebo (P) or beta-estradiol (2 mg/tablet, 3 tablets/day for 3 days). All experiments were conducted between 6:30 and 9:00 AM after ingestion of the last tablet. Heart rate, forearm blood flow (FBF), mean skin temperature, esophageal temperature (Tes), and forearm sweat rate were measured. Blood analysis for estrogen and progesterone reflected the follicular phase of the menstrual cycle. Maximal O2 consumption (37.1 +/- 6.2 in P vs. 38.4 +/- 6.3 ml. kg-1. min-1 in ES) and body weight-to-surface area ratio (35.58 +/- 2.85 in P vs. 37.3 +/- 2.7 in ES) were similar between groups. Synthesis of 70-kDa heat shock protein was not induced by 3 days of ES. Neither the threshold for sweating (36.97 +/- 0.15 in P vs. 36.90 +/- 0.22 degreesC in ES), the threshold for an increase in FBF (37.09 +/- 0. 22 in P vs. 37.17 +/- 0.26 degreesC in ES), the slope of sweat rate-Tes relationship (0.42 +/- 0.16 in P vs. 0.41 +/- 0.17 in ES), nor the FBF-Tes relationship (10.04 +/- 4.4 in P vs. 9.61 +/- 3.46 in ES) was affected (P > 0.05) by 3 days of ES. We conclude that 3 days of ES by young adult women in the follicular phase of their menstrual cycle have no effect on heat transfer to the skin, heat dissipation by evaporative cooling, or leukocyte synthesis of 70-kDa heat shock protein.

Elagolix is a nonpeptide, oral gonadotropin-releasing hormone (GnRH) antagonist being developed for sex-hormone-dependent diseases in women. We evaluated the pharmacokinetics and pharmacodynamics of elagolix. This study was a randomized, double-blind, placebo-controlled, multiple-ascending dose study in 45 healthy premenopausal women at a research unit. Elagolix [150 mg once daily or 100, 200, 300, or 400 mg twice daily (BID)] or placebo was administered for 21 days. Main outcome measures were elagolix pharmacokinetics, suppression of gonadotropics [follicle-stimulating hormone (FSH), luteinizing hormone (LH)] and ovarian hormones [estradiol (E2), progesterone (P)], and adverse events. Elagolix was rapidly absorbed after oral dosing, reaching maximum concentrations at 1.0 to 1.5 hours, with a half-life of 4 to 6 hours. FSH, LH, and E2 were suppressed within hours of elagolix administration on day 1. Dose-dependent suppression of E2 was observed, with maximum suppression achieved with elagolix 200 mg BID. Dose-dependent suppression of FSH and LH was also observed, with maximal or near-maximal suppression achieved at 300 mg BID and 200 mg BID, respectively. At elagolix doses ≥100 mg BID, P concentrations remained at anovulatory levels throughout 21 days of dosing. The most frequently reported adverse events were headache and hot flush. Elagolix administration allows for modulation of gonadotropin and ovarian hormone concentrations, from partial suppression at lower doses to nearly full suppression at higher doses. The results of this study provide a rationale for elagolix dose selection for treatment of sex hormone-dependent diseases in women. Copyright © 2017 Endocrine Society

Although relatively little is known about osteoporotic risk factors in women from the Indian subcontinent, osteoporotic fractures usually occur 10-20 years earlier in Indian men and women compared with their western Caucasian counterparts. The primary purpose of this cross-sectional study was to determine the relative contributions of ethnicity, reproductive history, body size (height, weight) and composition, bone turnover, serum 25(OH)vitamin D(3) [25(OH)D(3)], dietary intake (of calcium, fiber and alcohol) and energy expenditure to femoral bone mineral density (BMD) in Indian and Pakistani (Indian/Pakistani; n = 47) versus American (n = 47) Caucasians. We also contrasted femoral BMD and hip axis length in these two distinct groups of premenopausal females living in the USA. The Indian/Pakistani (0.875 +/- 0.096) women had lower (p = 0.0014) femoral BMD (g/cm(2)) than their American (0.937 +/- 0.088) counterparts, placing them at greater osteoporotic risk. However, the shorter (p = 0.0002) hip axis length (cm) of the Indian/Pakistani (10.54 +/- 0.57) versus American (11.11 +/- 0.78) Caucasians might attenuate hip fracture risk in the former group. Significant contributors to proximal femur BMD were maximum non-pregnant lifetime weight, age at menarche, ratio of summation sigma central-to-peripheral skinfold thicknesses, calcium intake from milk and usual alcohol intake. Although serum 25(OH)D(3) and urinary N-telopeptide concentrations did not contribute to femoral BMD in the regression models, the lower (p<0.0001) serum 25(OH)D(3) (33.1 +/- 16.5 vs 64.0 +/- 22.0 nmol/l) and higher (p = 0.0004) urinary N-telopeptide (45.9 +/- 43.3 vs 18.9 +/- 18.7 nmol BCE/mmol) values in Indian/Pakistani versus American Caucasians, respectively, coupled with their lower BMD, places the Indian/Pakistani women at greater osteoporotic risk. These results suggest that a clinical trial to increase BMD and reduce osteoporotic risk is warranted in this ethnic group of premenopausal

Among the opportunities and challenges facing the ESCAP region in the 21st century is the full and equal participation of women in all sectors of society, stated one of the representatives of the Republic of Korea at the Senior Officials segment of the 53rd session of the Commission. As a follow-up to the Fourth World Conference on Women, held at Beijing in 1995, her country passed the Women's Development Act, which entered into force in July 1996, she explained. It "provides a strong legal basis for adequate institutional and financial support towards the achievement of gender equality," which is also one of the goals of the Program of Action of the International Conference on Population and Development held at Cairo in 1994. In tandem with domestic efforts, enhancing cooperation at the regional and international levels is essential, she added. In a separate intervention, another member of the Korean delegation elaborated on the comments of his colleague. He pointed out that, "for the past 30 years, the Republic of Korea as a nation has done its best to alleviate the pressure of absolute poverty and has improved the quality of life through continued economic growth." He admitted, though, that rapid economic growth has brought about its own side effects -- "unsolved problems still remain such as residual absolute poverty and increasing relative poverty." Poverty alleviation policies aimed at creating equal opportunities must address four aspects, he noted: 1) maintenance and enhancement of health, 2) promotion of educational opportunities, 3) vocational training, and 4) employment promotion. full text

Since the end of the Korean War, immigration of Koreans to the United States has increased rapidly. In 1990, 11.6 percent of all Asians in the United States were of Korean ethnicity, and it is projected that Koreans will outnumber all other Asian groups, except Filipinos, in the United States by the year 2030. Despite the growing size of this population, very little is known about their health status. This study, using 1979-89 Hawaii vital record data, investigates the relationship between maternal sociodemographic characteristics, prenatal care utilization factors, and birth outcomes among Koreans as compared with Caucasians. The ethnic term "Caucasian" is used in Hawaii's vital records and is synonymous with non-Hispanic whites. Korean mothers were more likely to be older and have lower educational attainment, and less likely to be adolescent, single, or to have received adequate prenatal care than Caucasian mothers. More than 80 percent of the Korean mothers were foreign born. Significantly higher risks for very preterm delivery (less than 33 weeks) and very low birth weight births were observed for Koreans as compared with Caucasians. Nativity had no effect on birth outcome in this population. The results of this study suggest that prevention of preterm birth is an important focus for improving pregnancy outcomes in this growing ethnic group. PMID:8341786

Stromal factors have been identified as important for tumorigenesis and metastases of breast cancer. From 49 premenopausal women, samples were collected from benign or malignant tumors and the seemingly normal tissue adjacent to the tumor. The factors studied, with real-time polymerase chain reaction (PCR) and immunohistochemistry, were cyclooxygenase-1 and cyclooxygenase-2 (COX-1 and COX-2), syndecan-1 (S-1) and connective tissue growth factor (CTGF). COX-1 and S-1 mRNA levels were higher in the malignant tumors than in normal and benign tissues. The COX-2 mRNA level was lower in the malignant tumor than in the normal tissue, while CTGF mRNA did not differ between the groups. COX-1 immunostaining was higher in stroma from malignant tumors than in benign tissues, whereas COX-2 immunostaining was higher in the malignant tissue. Glandular S-1 immunostaining was lower in malignant tumors compared to benign and normal tissues, and the opposite was found in stroma. Conclusively, mRNA levels of COX-1 and COX-2 were oppositely regulated, with COX-1 being increased in the malignant tumor while COX-2 was decreased. S-1 protein localization switched from glandular to stromal cells in malignant tissues. Thus, these markers are, in premenopausal women, localized and regulated differently in normal/benign breast tissue as compared to the malignant tumor.

Both iron deficiency and iron deficiency anemia are common in the United States with a prevalence amongst women of 12 % and 4 % respectively. These numbers are even higher in African-American women (AAW) and are often a result of heavy menstrual bleeding (HMB). The primary objective of this study was to determine if perceived assessment of menstrual bleeding was associated with objective and subjective measures of anemia in AAW. Quantitative cross-sectional pilot study with surveys and venipuncture. 44 premenopausal AAW (mean age 37.9 years ± 9. 4) participated in the study. Iron deficiency was present in 68.2 % of the participants and 18.2 % were anemic. Almost half of the participants reported that their menses were heavy or very heavy, and there was a relationship between perceived heaviness of menstrual flow and anemia (P = 0.021). Of the individuals who reported that their menses were heavy or very heavy, 35.0 % were anemic. AAW who reported heavy or very heavy menses had significantly lower hemoglobin (P = 0.015), hematocrit (P = 0.003), and ferritin (P = 0.012) levels, as well as more general (P = 0.006) and menses-associated symptoms of anemia (P = 0.015) than those who reported normal or light menses. This pilot study of premenopausal AAW found that a significant percentage of women who report HMB are not only iron deficient, but also anemic. AAW should be educated on the consequences of HMB and counseled to seek care with a women's health provider when they perceive HMB. More importantly, providers should be aware that when AAW report HMB, evaluation for iron deficiency and anemia are essential.

Objective The present study identified and compared the coping strategies of Chinese-, Korean-, and Mexican-American breast cancer survivors (BCS). Methods Six focus groups were conducted with Chinese- (n = 21), Korean- (n = 11), and Mexican-American (n = 9) BCS. Interviews were audio-recorded, transcribed, and translated for thematic content analysis of coping experiences and strategies. Results Women reported the use of eight coping strategies (religious/spiritual, benefit finding, fatalism, optimism, fighting spirit, information seeking, denial, and self-distraction). Among Chinese-American BCS, benefit finding was the most referenced coping strategy, whereas religious/spiritual coping was most frequently reported among Korean- and Mexican-American BCS. Denial and self-distraction were the least cited strategies. Conclusions Survivors draw upon new found inner strength to successfully integrate their cancer experience into their lives. Coping models must consider the diversity of cancer survivors and the variability in coping strategies among cultural ethnic minority BCS. PMID:26389720

This research examines the influence of messages from religious leaders and congregants on whether Korean women are overweight or obese. Data were drawn from telephone interviews with a probability sample (N=591) of women of Korean descent living in California. Overweight or obese prevalence was measured using World Health Organization standards for Asians (BMI>23). Respondents reported the frequency of messages discouraging “excessive eating” or encouraging “exercise” from religious leaders and congregants during a typical month. When conditioned on leaders’ messages, the frequency of congregants’ messages was associated with a significantly lower probability of being overweight or obese, although messages from either in the absence of the other were unassociated with being overweight or obese. At least for Korean women, religion may help prevent obesity via religious-based social mechanisms. PMID:20886700

Background: Caffeinated beverages are widely consumed among women of reproductive age, but their association with reproductive hormones, and whether race modifies any such associations, is not well understood. Objective: We assessed the relation between caffeine and caffeinated beverage intake and reproductive hormones in healthy premenopausal women and evaluated the potential effect modification by race. Design: Participants (n = 259) were followed for up to 2 menstrual cycles and provided fasting blood specimens for hormonal assessment at up to 8 visits per cycle and four 24-h dietary recalls per cycle. Weighted linear mixed models and nonlinear mixed models with harmonic terms were used to estimate associations between caffeine and hormone concentrations, adjusted for age, adiposity, physical activity, energy and alcohol intakes, and perceived stress. On the basis of a priori assumptions, an interaction between race and caffeine was tested, and stratified results are presented. Results: Caffeine intake ≥200 mg/d was inversely associated with free estradiol concentrations among white women (β = −0.15; 95% CI: −0.26, −0.05) and positively associated among Asian women (β = 0.61; 95% CI: 0.31, 0.92). Caffeinated soda intake and green tea intake ≥1 cup/d (1 cup = 240 mL) were positively associated with free estradiol concentrations among all races: β = 0.14 (95% CI: 0.06, 0.22) and β = 0.26 (95% CI: 0.07, 0.45), respectively. Conclusions: Moderate consumption of caffeine was associated with reduced estradiol concentrations among white women, whereas caffeinated soda and green tea intakes were associated with increased estradiol concentrations among all races. Further research is warranted on the association between caffeine and caffeinated beverages and reproductive hormones and whether these relations differ by race. PMID:22237060

The study examined the subjective life experiences of elderly first-generation Korean women living in Japan and investigated their adjustment to the local Japanese community. The study group comprised 14 elderly Korean women residents at a Korean-oriented, insurance-based, day services center in midwestern Japan. They were interviewed in depth, and the data were analyzed using the modified grounded theory approach. The study designated the core category as "conservation of ethnic identity" and identified five subcategories: (a) loneliness, (b) returning to one's homeland culture, (c) physical decline as a result of aging, (d) family ties, and (e) a place where one belongs. The results elucidated that although the participants had adapted to Japanese culture, they were strongly influenced by the memories of their hometowns and wished to return to their homeland. The study suggests that elderly immigrants need day care support that provides an environment where they can enjoy their culture.

The objective of the study was to investigate the association between metabolic syndrome (MS) and muscle strength in community-dwelling older men and women in Korea. Korean men and women 65 years and older living in a single, typical South Korean city (n = 647) were enrolled in the Korean Longitudinal Study on Health and Aging study. The diagnosis of MS was evaluated according to the definition of the National Cholesterol Education Program Adult Treatment Panel III. Isokinetic muscle strength of the knee extensors, as determined by peak torque per body weight (newton meter per kilogram) and hand-grip strength per body weight (newton per kilogram), was measured. Participants without MS had greater leg muscle strength and grip strength per weight. The effect of MS on muscle strength was more prominent in men than in women in our study population. Only men showed a significant interaction between MS and age for muscle strength (P = .014), and the effect was greater in men aged 65 to 74 years compared with those older than 75 years (119.2 ± 31.2 vs 134.5 ± 24.3 N m/kg). Participants with MS had weaker knee extensor strength after controlling the covariates (β = -90.80, P = .003), and the interaction term (age × MS × male sex) was significant (β = 1.00, P = .017). Metabolic syndrome is associated with muscle weakness, and this relationship is particularly pronounced in men. Age can modify the impact of MS on muscle strength. Men aged 65 to 74 years with MS need a thorough assessment of muscle strength to prevent disability. Copyright © 2012 Elsevier Inc. All rights reserved.

A convenience sample of 40 native-born pregnant Korean women receiving prenatal care at a U.S. military facility in a major metropolitan area in Korea completed a questionnaire about attitudes toward pregnancy and prenatal care. Responses revealed a family life characterized by positive maternal and paternal perceptions of the pregnancy and less preference for a male child than we had anticipated. Traditional beliefs in Tae Mong, a conception dream, and Tae Kyo, rituals for safe childbirth, were followed. Food taboos, including protein sources, were reported. Attitudes toward prenatal care services, care providers, and maternal health habits are described.

Mammographic breast density is a known risk factor for breast cancer. To conduct a survey to estimate the distribution of mammographic breast density in Korean women, appropriate sampling strategies for representative and efficient sampling design were evaluated through simulation. Using the target population from the National Cancer Screening Programme (NCSP) for breast cancer in 2009, we verified the distribution estimate by repeating the simulation 1,000 times using stratified random sampling to investigate the distribution of breast density of 1,340,362 women. According to the simulation results, using a sampling design stratifying the nation into three groups (metropolitan, urban, and rural), with a total sample size of 4,000, we estimated the distribution of breast density in Korean women at a level of 0.01% tolerance. Based on the results of our study, a nationwide survey for estimating the distribution of mammographic breast density among Korean women can be conducted efficiently.

This qualitative grounded theory study explored stress-coping mechanisms in 14 Korean immigrant women (age ≥40) in the USA, by analyzing existing focus group data about relevant concepts that had been collected in a parent study. Using content analysis, stressors related primarily to socioenvironmental changes following immigration: language barriers, lack of trusting human relationships, and role changes were identified. Both healthy (activities, church, staying busy) and unhealthy (being alone and keeping negative feelings inside) coping strategies were reported by participants. The findings reveal unique aspects of stress-coping among Korean women who had immigrated after being culturally engrained with Confucian influences.

Abstract Background: The role of body fatness in the aetiology of breast cancer is complex. We evaluated the independent and synergistic effects of body fatness, at different stages throughout a woman's life course, on premenopausal breast cancer risk. Methods: Premenopausal participants of the Nurses’ Health Study II (NHSII) were followed from 1991 up to 2009. Body fatness factors including birthweight, somatotype (a 9-level pictogram with level 1 being the leanest) at ages 5 and 10 years and body mass index (BMI) at age 18 were collected at baseline. Current BMI was updated biennially. Multivariate Cox regression models were used to evaluate the association between each body fatness factor as well as cross-classification of all factors and the incidence of breast cancer. Results: Based on 1574 incident premenopausal breast cancer cases and 1 133 893 person-years of follow-up, a lower incidence was associated with lower birthweight: hazard ratio (HR) [95% confidence interval (CI)] = 0.74 (0.58–0.95) for <2.5kg vs 3.9+kg, P for trend < 0.001; higher somatotype at age 5: HR=0.57 (95% CI 0.44–0.73) for 5–9 vs 1, P fortrend < 0.0001]; and at age 10: HR=0.61 (95% CI 0.49–0.75) for 5–9 vs 1, P for trend < 0.0001]; and BMI at age 18: HR=0.67 (95% 0.47–0.95) for ≥ 27.5 kg/m2 vs < 18.5 kg/m2, P for trend = 0.009], after adjusting for age and body fatness measures earlier in life and other risk factors, respectively. No significant interaction between body fatness measures was found. Women with the lowest birthweight, the highest somatotype at ages 5 and 10 and the highest BMI at age 18 and currently had a 72% (95% CI 54%-83%) lower incidence of invasive premenopausal breast cancer than women with the opposite extreme of each body fatness indicator. Conclusion: The lowest incidence of premenopausal breast cancer was associated with the lowest birthweight and the highest childhood, adolescent and early adult body fatness. PMID:27466312

This controlled feeding study examined the effects of exercise on daily water intake (particularly ad libitum water intake), water output, whole-body water balance, and hydration status in physically active, premenopausal women. The randomized crossover design consisted of three 8-day trials: placebo and no exercise, placebo and exercise (1-hour cycling bout per day at 65%-70% of heart rate reserve), and 800 mg calcium supplementation and exercise. During each trial, controlled quantities of the same foods and beverages were provided and ad libitum water intake was quantified. Water input included measured water from foods and beverages, measured ad libitum intake, and estimated metabolic production. Water output included measured losses in urine and stool, and estimated insensible losses from respiration and non-sweating perspiration (insensible diffusion through the skin). Participants were 26 women, age 25+/-5 years, body mass index 22+/-2, and VO(2peak) 43+/-6 mLxkg(-1)xmin(-1) (mean+/-standard deviation). Ad libitum water intake was 363 g/day more (P<0.05) for the placebo and exercise (1,940+/-654 g/day) and calcium supplementation and exercise (1,935+/-668 g/day) trials, compared with placebo and no exercise trial (1,575+/-667 g/day), and total water input was correspondingly higher in placebo and exercise and calcium supplementation and exercise trials compared with the placebo and no exercise trial. Urine, stool, and total water outputs were not different among trials. Apparent net water balance (representative of sweat water output) was 367 g/day more (P<0.05) in placebo and exercise (679+/-427 g/day) and calcium supplementation and exercise (641+/-519 g/day) trials compared with placebo and no exercise trial (293+/-419 g/day). Hydration status was clinically normal during all three trials. Calcium supplementation did not influence water balance. These results support that young, physically active women can completely compensate for exercise-induced sweat

Although Yoga has the potential to be an alternative physical activity to enhance bone health, there is a lack of high quality evidence for this type of intervention. The purpose of this randomized controlled trial was to examine the effects of a progressive 8-month Ashtanga-based Yoga program on bone turnover markers (BTM), areal bone mineral density (aBMD) and volumetric bone characteristics in premenopausal women. Thirty-four premenopausal women (35-50 years) were randomly assigned either to a Yoga group (YE, n = 16) or a control group (CON, n = 18). Participants in YE group performed 60 minutes of an Ashtanga-based Yoga series 2 times/week with one day between sessions for 8 months, and the session intensity was progressively increased by adding the number of sun salutations (SS). Participants in CON were encouraged to maintain their normal daily lifestyles monitored by the bone specific physical activity questionnaire (BPAQ) at 2 month intervals for 8 months. Body composition was measured by dual energy x-ray absorptiometry (DXA). Bone formation (bone alkaline phosphatase, Bone ALP) and bone resorption (Tartrate-Resistant Acid Phosphatase-5b, TRAP5b) markers were assessed at baseline and after 8 months. aBMD of total body, lumbar spine and dual proximal femur and tibia bone characteristics were measured using DXA and peripheral Quantitative Computed Tomography (pQCT), respectively. We found that the serum Bone ALP concentrations were maintained in YE, but significantly (p = 0.005) decreased in CON after the 8 month intervention, and there were significant (p = 0.002) group differences in Bone ALP percent changes (YE 9.1 ± 4.0% vs. CON -7.1 ± 2.3%). No changes in TRAP5b were found in either group. The 8-month Yoga program did not increase aBMD or tibia bone strength variables. Body composition results showed no changes in weight, fat mass, or % fat, but small significant increases in bone free lean body mass occurred in both groups. The findings of this study

The lemon detox program is a very low-calorie diet which consists of a mixture of organic maple and palm syrups, and lemon juice for abstinence period of 7 days. We hypothesized that the lemon detox program would reduce body weight, body fat mass, thus lowering insulin resistance and known risk factors of cardiovascular disease. We investigated anthropometric indices, insulin sensitivity, levels of serum adipokines, and inflammatory markers in overweight Korean women before and after clinical intervention trial. Eighty-four premenopausal women were randomly divided into 3 groups: a control group without diet restriction (Normal-C), a pair-fed placebo diet group (Positive-C), and a lemon detox diet group (Lemon-D). The intervention period was 11 days total: 7 days with the lemon detox juice or the placebo juice, and then 4 days with transitioning food. Changes in body weight, body mass index, percentage body fat, and waist-hip ratio were significantly greater in the Lemon-D and Positive-C groups compared to the Normal-C group. Serum insulin level, homeostasis model assessment insulin resistance scores, leptin, and adiponectin levels decreased in the Lemon-D and Positive-C groups. Serum high-sensitive C-reactive protein (hs-CRP) levels were also reduced only in the Lemon-D group. Hemoglobin and hematocrit levels remained stable in the Lemon-D group while they decreased in the Positive-C and Normal-C groups. Therefore, we suppose that the lemon detox program reduces body fat and insulin resistance through caloric restriction and might have a potential beneficial effect on risk factors for cardiovascular disease related to circulating hs-CRP reduction without hematological changes.

Introduction: Several authors have linked subclinical ovulatory disturbances in normal length menstrual cycles to premenopausal fracture risk and bone changes. This study systematically examined the influence of ovulation and anovulation on the bone metabolism of premenopausal women. Participants and Methods: In 176 cycles in healthy premenopausal women, FSH, 17β-estradiol (E2) and progesterone (P4) as well as bone alkalic phosphatase (BAP), pyridinoline (PYD) and C-terminal crosslinks (CTX) were measured during the follicular and during the luteal phase. The probability and timing of ovulation was self-assessed by a monitoring device. In addition, bone density of the lumbar spine was measured by quantitative computed tomography (QCT) at baseline and at the end of the study. Analysis was restricted to blood samples taken more than three days before the following menstruation. Results: 118 cycles out of the 176 collected cycles were complete with blood samples taken within the correct time interval. Of these, 56.8 % were ovulatory by two criteria (ovulation symbol shown on the monitor display and LP progesterone > 6 ng/ml), 33.1 % were possibly ovulatory by one criterion (ovulation symbol shown on the monitor display or LP progesterone > 6 ng/ml), and 10.2 % were anovulatory by both criteria). Ovulation in the previous cycle and in the same cycle did not significantly influence the mean absolute concentrations of the bone markers. However, bone formation (BAP) was higher in the luteal phase of ovulatory cycles than in anovulatory cycles (n. s.) and the relative changes within one cycle were significantly different for bone resorption (CTX) during ovulatory vs. anovulatory cycles (p < 0.01). In 68 pairs of cycles following each other directly, both ovulation in the previous cycle and ovulation in the present cycle influenced CTX, but not the differences of other bone markers. Conclusion: Ovulatory cycles reduce bone resorption in their luteal

Socioeconomic disparity in cervical cancer screening among Korean women: 1998–2010

Background Cervical cancer is the sixth most common cause of cancer among Korean women and is one of the most preventable cancers in the world. This study aimed to investigate the change in cervical cancer screening rates, the level of socioeconomic disparities in cervical cancer screening participation, and whether there was a reduction in these disparities between 1998 and 2010. Methods Using the Korean Health and Nutrition Examination Survey, women 30 years or older without a history of cervical cancer and who completed a health questionnaire, physical examination, and nutritional survey were included (n = 17,105). Information about participation in cervical cancer screening was collected using a self-administered questionnaire. Multiple logistic regression analysis was performed to investigate the relationship between cervical cancer screening participation and the socioeconomic status of the women. Results The cervical cancer screening rate increased from 40.5% in 1998 to 52.5% in 2010. Socioeconomic disparities influenced participation, and women with lower educational levels and lower household income were less likely to be screened. Compared with the lowest educational level, the adjusted odds ratios (ORs) for screening in women with the highest educational level were 1.56 (95% confidence interval (CI): 1.05–2.30) in 1998, and 1.44 (95% CI: 1.12–1.87) in 2010. Compared with women with the lowest household income level, the adjusted ORs for screening in women with the highest household income level were 1.80 (95% CI: 1.22–2.68), 2.82 (95% CI: 2.01–3.96), and 1.45 (95% CI: 1.08–1.94) in 2001, 2005, and 2010, respectively. Conclusion Although population-wide progress has been made in participation in cervical cancer screening over the 12-year period, socioeconomic status remained an important factor in reducing compliance with cancer screening.

Alteration of menstrual cycle by individual lifestyles and unfavorable habits may cause menstrual irregularity. We aimed to investigate the relationship between lifestyle factors and menstrual irregularity in Korean women using data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012. This cross-sectional study included 3779 nondiabetic Korean women aged 19-49 years who did not take any oral contraceptives or sex hormonal compounds. We examined the association of menstrual irregularity with age, body mass index (BMI), drinking experience, and smoking habits. Age, Asian BMI, marriage status, age at menarche, and smoking habits were significantly associated with menstrual cycle irregularity (p < 0.01). The prevalence of menstrual irregularity was significantly increased at younger ages: 18.4%, 10.3%, and 10.5% at 19-29, 30-39, and 40-49 years, respectively. Moreover, obesity groups, defined as per Asian BMI using modified WHO criteria, were strongly associated with menstrual irregularity. BMI 25.0-29.9 [obesity class I] (adjusted odds ratios [OR], 1.94; 95% confidence intervals [CI], 1.37-2.74) and ≥30.0 [obesity class II] (adjusted OR, 2.18; 95% CI, 1.22-3.91) presented significantly higher risk of menstrual irregularity compared with BMI 18.5-22.9 [normal weight]. Multivariable analysis revealed that high BMI in younger women aged 19-29 years (p < 0.001) and smoking habits in middle-aged women aged 30-39 years (p < 0.005) significantly predicted menstrual irregularity. This study substantiated that menstrual irregularity was closely associated with higher BMI and smoking habits in nondiabetic Korean women. Weight loss and smoking cessation should be recommended to promote women's reproductive health.

We have previously reported that premenopausal women with idiopathic osteoporosis (IOP) have profound microarchitectural deficiencies and heterogeneous bone remodeling. Those with the lowest bone formation rate have higher baseline serum insulin-like growth factor-1 (IGF-1) levels and less robust response to teriparatide. Because IGF-1 stimulates bone formation and is critical for teriparatide action on osteoblasts, these findings suggest a state of IGF-1 resistance in some IOP women. To further investigate the hypothesis that osteoblast and IGF-1-related mechanisms mediate differential responsiveness to teriparatide in IOP, we studied circulating osteoblast progenitor (COP) cells and their IGF-1 receptor (IGF-1R) expression. In premenopausal women with IOP, peripheral blood mononuclear cells (PBMCs) were obtained at baseline (n = 25) and over 24 months of teriparatide treatment (n = 11). Flow cytometry was used to identify and quantify COPs (non-hematopoetic lineage cells expressing osteocalcin and RUNX2) and to quantify IGF-1R expression levels. At baseline, both the percent of PBMCs that were COPs (%COP) and COP cell-surface IGF-1R expression correlated directly with several histomorphometric indices of bone formation in tetracycline-labeled transiliac biopsies. In treated subjects, both %COP and IGF-1R expression increased promptly after teriparatide, returning toward baseline by 18 months. Although neither baseline %COP nor increase in %COP after 3 months predicted the bone mineral density (BMD) response to teriparatide, the percent increase in IGF-1R expression on COPs at 3 months correlated directly with the BMD response to teriparatide. Additionally, lower IGF-1R expression after teriparatide was associated with higher body fat, suggesting links between teriparatide resistance, body composition, and the GH/IGF-1 axis. In conclusion, these assays may be useful to characterize bone remodeling noninvasively and may serve to predict early response to

Systemic lupus erythematosus (SLE) predominantly affects women in their reproductive years and has a significant impact on childbearing. We investigated the influence of personal decision on family size among Korean women with SLE and factors that affect the decisions. A case-control study comparing childbearing history and decisions of 112 SLE patients and 135 controls was performed. Women with SLE participating in the Network for Lupus Clinical Research in South Korea and matching controls between ages of 18-45, who are/were married or living with a partner were included. Data regarding socio-demographics, reproductive history, and childbearing decisions were collected through a survey using a standardized questionnaire and medical record review. More women with SLE reported at least one pregnancy (85.7% vs. 71.9%, P = 0.009) or at least one live birth (85.7% vs. 71.9%, P = 0.003) compared with controls. Mean number of pregnancies was significantly higher (2.4 ± 1.6 vs. 1.4 ± 1.3, P < 0.001), and mean number of live births was significantly lower in women with SLE (1.2 ± 0.8 vs. 1.6 ± 0.8, P < 0.001). Significantly more women with SLE made the decision not to have children compared with controls (54.5% vs. 40.7%, P = 0.031), and health-related concerns were the major cause of the decision. Other socio-demographic factors did not influence the decision to limit childbearing in SLE women. The disease-related concerns had significant impact on family size and childbearing decisions among Korean women with SLE. PMID:27134494

We investigated the vitamin D status of Korean women during pregnancy and assessed the effects of vitamin D deficiency on two pregnancy outcomes; preterm births and the births of small for gestational age. We measured the serum 25-hydroxyvitamin D levels in 220 pregnant Korean women who were recruited prospectively and compared these levels with those of 500 healthy non-pregnant women. We analyzed vitamin D status according to patient demographics, season, and obstetrical characteristics; moreover, we also assessed pregnancy outcomes. The overall prevalence of vitamin D deficiency(<20 ng/mL) in pregnant women and healthy non-pregnant women was 77.3% and 79.2%; respectively; and the prevalence of severe vitamin D deficiency (<10 ng/mL) was 28.6% and 7.2%; respectively (p < 0.05). Vitamin D deficiency was more prevalent in the winter (100%) than in the summer (45.5%) in pregnant Korean women. A higher risk of vitamin D deficiency was observed in the first trimester than in the third trimester (adjusted OR 4.3; p < 0.05). No significant association was observed between vitamin D deficiency and any of the pregnancy outcomes examined. Further research focusing on the long-term consequences of vitamin D deficiency during pregnancy in Korean women is warranted.

Age-adjusted incidence of cardiovascular disease, including myocardial infarction, is significantly lower in premenopausal women than in men, which is thought to be caused by the cardioprotective effects of estrogen. However, there is a consistent increase in the incidence of coronary artery disease in postmenopausal women in comparison with premenopausal women. The protective benefit of hormone therapy has not been observed in postmenopausal women. It is unknown whether measures of platelet reactivity and clot strength contribute to the disproportionate incidence of cardiovascular disease between premenopausal and postmenopausal women. Fifty healthy volunteers, including 25 premenopausal women and 25 postmenopausal women, aged between 40 and 65 years were enrolled. Total estradiol and follicle-stimulating hormone levels were measured for confirmation of menopausal state and comparison testing. Platelet reactivity was assessed using light transmission aggregometry and P-selectin, and glycoprotein IIb/IIIa receptor expression was assessed using flow cytometry. Thrombelastography was used to measure clot strength, clotting time, and fibrinogen activity. Serum cholesterol, C-reactive protein, complete blood count, and comprehensive metabolic panel were also measured. Platelet reactivity did not differ among menopausal states or hormone levels. Clotting time was increased in postmenopausal women (6.6 ± 2.0 vs. 7.8 ± 1.2 min, P = 0.013) and significantly correlated with estradiol levels (r = 0.68, P < 0.001). A significantly higher low-density lipoprotein cholesterol level was observed in postmenopausal women (P = 0.05). Mean C-reactive protein levels were numerically higher in the postmenopausal group. The thrombotic risk profile between premenopausal and postmenopausal women is similar. However, improved management of cholesterol may be of clinical benefit. Large-scale studies are required to validate these findings.

We examined the prevalence, correlates, comorbidities, and suicidal tendencies of premenstrual dysphoric disorder (PMDD) according to the DSM-IV criteria in a nationwide sample of Korean women. A total of 2,499 women aged 18-64 years participated in this study. Diagnostic assessments were based on the Korean version of the Composite International Diagnostic Interview (CIDI) 2.1 and its 12-month PMDD diagnostic module, which were administered by lay interviewers. The frequencies of DSM-IV psychiatric disorders, insomnia, and suicidal tendency were analyzed among PMDD cases and compared with non-PMDD cases, and both odds ratios and significance levels were calculated. The 12-month prevalence rate of DSM-IV-diagnosed PMDD was 2.4 %. Among subjects with PMDD, 59.3 % had at least one psychiatric illness; in comparison, the control frequency was 21.8 %. Associations between PMDD and alcohol abuse/dependence, major depressive disorder, post-traumatic stress disorder, social phobia, specific phobia, somatoform disorder, insomnia, and suicidality were overwhelmingly positive and significant (p < 0.05), after controlling for age. Physical illness and being underweight were associated with increased risks of PMDD (p < 0.05). PMDD was prevalent in the nationwide sample of Korean women and was frequently associated with other psychiatric disorders, insomnia, and suicidality, suggesting the need to detect and treat women who experience PMDD.

Weight loss improves metabolic fitness and reduces morbidity and mortality; however, weight reduction also reduces bone mineral density (BMD) and increases bone turnover. Weight-bearing aerobic exercise may preserve bone mass and maintain normal bone turnover during weight reduction. We investigated the impact of weight-bearing and nonweight-bearing exercise on serum markers of bone formation and breakdown during short-term, modest weight loss in overweight premenopausal women. Subjects (n = 36) were assigned to 1 of 3 weight-loss interventions designed to produce a 5% reduction in body weight over 6 weeks: (i) energy restriction only (n = 11; DIET); (ii) energy restriction plus nonweight-bearing exercise (n = 12, CYCLE); or (iii) energy restriction plus weight-bearing exercise (n = 13, RUN). Bone turnover markers were measured in serum collected at baseline and after weight loss. All groups achieved a ~5% reduction in body weight (DIET = 5.2%; CYCLE = 5.0%; RUN = 4.7%). Osteocalcin (OC) and C-terminal telopeptide of type I collagen (CTX) increased with weight loss in all 3 groups (p < 0.05), whereas bone alkaline phosphatase was unaltered by the weight-loss interventions. At baseline, OC and CTX were positively correlated (r = 0.36, p = 0.03), but the strength of this association was diminished (r = 0.30, p = 0.06) after weight loss. Modest weight loss, regardless of method, resulted in a significant increase in both OC and CTX. Low-impact, weight-bearing exercise had no effect on serum markers of bone formation or resorption in premenopausal women during weight loss. Future studies that examine the effects of high-impact, weight-bearing activity on bone turnover and BMD during weight loss are warranted.

Multivariable analysis revealed that high BMI in younger women aged 19–29 years (p < 0.001) and smoking habits in middle-aged women aged 30–39 years (p < 0.005) significantly predicted menstrual irregularity. Conclusion: This study substantiated that menstrual irregularity was closely associated with higher BMI and smoking habits in nondiabetic Korean women. Weight loss and smoking cessation should be recommended to promote women's reproductive health. PMID:27603944

This research identifies social reinforcers within religious institutions associated with alcohol consumption among Korean women in California. Data were drawn from telephone interviews with female adults (N = 591) selected from a random sampling of persons in California with Korean surnames during 2007. Approximately 70% of attempted interviews were completed, with 92% conducted in Korean. Respondents were asked about any lifetime drinking (yes/no), drinking rate (typical number of drinks consumed on drinking days among current drinkers), and messages discouraging "excessive drinking" from religious leaders or congregants. Bivariable and multivariable regressions were used for analysis. Approximately 70.4% of women reported any lifetime drinking, and drinkers drank a mean (SD) of 1.10 (1.22) drinks on drinking days. About 30.8% reported any exposure to religious leaders' messages discouraging excessive drinking, and 28.2% reported any exposure to similar messages from congregants. Each congregant's message was statistically significantly associated with a 5.1% lower probability (odds ratio = 0.775, 95% confidence interval [CI]: 0.626, 0.959) of any lifetime drinking. also, each congregant's message was associated with a 13.8% (B = -0.138; 95% CI: -0.306, 0.029) lower drinking rate, which was statistically significant after adjusting for covariates using a one-tailed test. Exposure to leaders' messages was not statistically significantly associated with any lifetime drinking or drinking rate. Social reinforcement in the form of religious messages may be one mechanism by which religious institutions influence drinking behaviors. For Korean women, messages from congregants had a unique impact beyond the traditional religiosity indicators. These social mechanisms provide public health interventionists with religious pathways to improve drinking behaviors.

The anti-inflammatory mechanisms of low-fat dairy product consumption are largely unknown. The objective of this study was to determine whether low-fat yogurt reduces biomarkers of chronic inflammation and endotoxin exposure in women. Premenopausal women (BMI 18·5-27 and 30-40 kg/m2) were randomised to consume 339 g of low-fat yogurt (yogurt non-obese (YN); yogurt obese (YO)) or 324 g of soya pudding (control non-obese; control obese (CO)) daily for 9 weeks (n 30/group). Fasting blood samples were analysed for IL-6, TNF-α/soluble TNF II (sTNF-RII), high-sensitivity C-reactive protein, 2-arachidonoyl glycerol, anandamide, monocyte gene expression, soluble CD14 (sCD14), lipopolysaccharide (LPS), LPS binding protein (LBP), IgM endotoxin-core antibody (IgM EndoCAb), and zonulin. BMI, waist circumference and blood pressure were also determined. After 9-week yogurt consumption, YO and YN had decreased TNF-α/sTNFR-RII. Yogurt consumption increased plasma IgM EndoCAb regardless of obesity status. sCD14 was not affected by diet, but LBP/sCD14 was lowered by yogurt consumption in both YN and YO. Yogurt intervention increased plasma 2-arachidonoylglycerol in YO but not YN. YO peripheral blood mononuclear cells expression of NF-κB inhibitor α and transforming growth factor β1 increased relative to CO at 9 weeks. Other biomarkers were unchanged by diet. CO and YO gained approximately 0·9 kg in body weight. YO had 3·6 % lower diastolic blood pressure at week 3. Low-fat yogurt for 9 weeks reduced biomarkers of chronic inflammation and endotoxin exposure in premenopausal women compared with a non-dairy control food. This trial was registered as NCT01686204.

The study investigated the association between childbirth history and health-related quality of life (QOL) in menopausal South Korean women. Cross-sectional analysis of data from the 2010-2012 Korean National Health and Nutrition Examination Surveys (KNHANES) for 4277 menopausal women aged over 50. We used the EuroQol index to measure health-related QOL. The relationship between delivery history and health-related QOL in menopausal South Korean women was analyzed. After adjustment for age (model 1), women who were younger at their first delivery and who had a greater number of deliveries had a significantly higher risk of problems with mobility, self-care, usual activities and pain or discomfort; the risk of anxiety or depression was not increased. After adjustment for age, BMI, smoking, use of alcohol, exercise, income, education, marital status, metabolic syndrome and stress (model 2), women who were younger at their first delivery and who had a greater number of deliveries had a significantly higher risk of problems with mobility, self-care and pain or discomfort. Age at last delivery was not significantly associated with health-related QOL in either model. South Korean women who were younger at their first delivery and who had more deliveries appear to be at increased risk of health-related QOL problems after menopause.

The aim of this research is to estimate lifetime costs and health consequences for Korean adult women who were exposed to secondhand smoke (SHS) at home. A Markov model was developed to project the lifetime healthcare costs and health outcomes of a hypothetical cohort of Korean women who are 40 years old and were married to current smokers. The Korean epidemiological data were used to reflect the natural history of SHS-exposed and non-exposed women. The direct healthcare costs (in 2014 US dollars) and quality-adjusted life years (QALYs) were annually discounted at 5% to reflect time preference. The time horizon of the analysis was lifetime and the cycle length was 1 year. Deterministic and probabilistic sensitivity analyses were conducted. In the absence of SHS exposure, Korean women will live 41.32 years or 34.56 QALYs before discount, which corresponded to 17.29 years or 15.35 QALYs after discount. The SHS-exposed women were predicted to live 37.91 years and 31.08 QALYs before discount and 16.76 years and 14.62 QALYs after discount. The estimated lifetime healthcare cost per woman in the SHS non-exposed group was US$11 214 before the discount and US$2465 after discount. The negative impact of SHS exposure on health outcomes and healthcare costs escalated as the time horizon increased, suggesting that the adverse impact of SHS exposure may have higher impact on the later part of the lifetime. The result was consistent across a wide range of assumptions. Life expectancy might underestimate the impact of SHS exposure on health outcomes, especially if the time horizon of the analysis is not long enough. Early intervention on smoking behaviour could substantially reduce direct healthcare costs and improve quality of life attributable to SHS exposure. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

North Korean women defectors have suffered from anxiety, depression, and somatization after defection. Also they have had many menstrual problems like amenorrhea. This study was done to identify the correlations of anxiety, depression, and somatization to menstrual problems among North Korean woman defectors in South Korea. The participants in this study were 126 women from 5 government resettlement centers throughout South Korea. Questionnaires which included State-Trait Anxiety Inventory (STAI), Center for Epidemiological studies-Depression Scale (CED-S), and Symptom Checklist-90-Revised (SCL-90-R) were used to identify anxiety and somatization. Data were collected between June and September, 2012. The women reported the following problems; amenorrhea (9.5%), hypomenorrhea (13.6%), menorrhagia (19.8%), polymenorrhea (13.5%), oligomenorrhea (4.8%), changes in amount of menstrual discharge (4.0%), and changes in amount of blood clot (9.5%). Anxiety (r=0.20, p=0.002), depression (r=0.25, p=0.005), and Somatization (r=0.35, p<0.001) were correlated with number of menstrual problems. The results of this study indicate that mental health services need to be taken into account in interventions for North Korean woman defectors to improve their reproductive health including addressing menstrual problems.

This study evaluates the efficacy of an integrated health management program (IHMP) based on successful aging in older women. A single group pretest and posttest research design was employed, with a sample of 33 older Korean women over 60 years registered in a public health center. The intervention, including exercise, health education, and social activities, was performed 3 hr per week for 12 weeks. Demographic characteristics, body composition, physical fitness, biomarkers, depression, and social support were measured. Data were analyzed with a Wilcoxon signed-rank test, statistical significance levels were set at p < .05. After the intervention, body mass index was significantly decreased (p = .003) and skeletal muscle mass was significantly increased (p = .002). Chair stand (p = .023) and straight walking test (p < .001) were significantly improved. Systolic blood pressure (p < .003), diastolic blood pressure (p = .030), and blood cholesterol (p = .011) were significantly decreased. Depression (p = .043) was significantly decreased, and social support (p < .001) was significantly increased. Adopting and maintaining an IHMP can be useful to promote physical, psychological, and social functioning that lead to successful aging in older Korean women. © 2014 Wiley Periodicals, Inc.

The study evaluates the effectiveness of an ongoing, community-based breast cancer prevention program offered by a local social services agency in the Washington, DC, metropolitan area. Korean American women who participated in this breast cancer prevention program were compared with those who did not participate in their knowledge, attitude, and screening behaviors. The study found that the intervention group was more knowledgeable on breast cancer and related services and reported more positive attitudes toward breast cancer screening services than the comparison group. The participants in the intervention group were also more likely to plan to receive a mammogram than those in the comparison group. However, significant differences were not observed in the two groups in their intention to receive a clinical breast examination. The study findings suggest that an ongoing, community-based breast cancer prevention program can be an effective method of addressing breast cancer prevention disparities observed among Korean American women.

As coffee consumption is increasing remarkably over the past decade, the health effects concerning the coffee drinking has gained a wide attention across the nation. However, there is not a true consensus regarding the effects of coffee on metabolic disease. Therefore, this study aims to examine the association between coffee intake and the risk of metabolic syndrome in Korean women. We used publicly accessible datasets collected through Korean National Health and Nutrition Examination Survey (KNHANES). Among 20,435 individuals from five consecutive years' worth of data from 2007 to 2011, only 15,691 subjects qualified for statistical analysis upon applying the exclusion criteria. We carried out the statistical analysis utilizing SPSS Statistics version 13.0 (IBM Corp., Armonk, NY.) and STATA statistical software release 13.0 (STATA Corp., College Station, TX). We found that the frequency of coffee intake inversely correlates with the prevalence of metabolic syndrome in women. Upon adjusting for life-style factors, socioeconomic status, and nutritional profile, the subjects from the highest coffee consumption quartile exhibited 40% lower odds of suffering from metabolic syndrome compared to those in the control (OR = 0.75; 95% CI = 0.67-0.84; P for trend < 0.001). Also, we observed that age- and BMI-adjusted HOMA-IR decreased as the coffee consumption increased (P for trend < 0.001). The findings of our study suggest that coffee consumption might be associated with reduction of metabolic syndrome in Korean women. To elucidate this cross-sectional association between coffee consumption and metabolic syndrome in women, cohort studies are warranted to confirm this relationship.

Safety of strength training in premenopausal women: musculoskeletal injuries from a two-year randomized trial.

The health benefits of strength training must be weighed against risks, including injuries. A prior study observed 4.2 injuries that limited usual activities for a day per 1000 strength training sessions among men and women. The analysis herein explores the incidence rates of musculoskeletal injuries from strength training in women. Randomized controlled trial. SETTING; Free-living community. A total of 163 injury-free, overweight, sedentary, premenopausal women aged 25 to 44 years. Two years of strength training (n = 81) or standard care (n = 82). The intervention followed published guidelines (U.S. Department of Health and Human Services) with hypothesized injury prevention strategies. An injury survey was administered at years 1 and 2. Injury was defined as physical activity or strength training associated injuries that limited daily activities for 1 week or more. Denominators for rate calculation were accelerometer-measured physical activity and strength training attendance (strength training only). The between-group probability of injuries was assessed using generalized estimating equations. Injury incidence rates were higher in strength training compared with standard care. In strength training, the injury rates were 3.6 per 1000 strength training sessions (95% confidence interval: 2.5-4.8 per 1000) for physical activity-related injuries, and 2.6 per 1000 (95% confidence interval: 1.5-3.6 per 1000) for strength training-related injuries. Injury rates varied by definition and denominator. Strength training had lower injury rates than previously reported, providing preliminary support for the prevention strategies. The finding of strength training injuries underscores the need for balancing the benefits against the potential risks of this exercise modality.

This study extends Bernstein et al.'s (2016) investigation of the effects of the Enhanced Logo-autobiography Program on Korean-American women's depressive symptoms, coping strategies, purpose in life, and posttraumatic growth by analyzing quantitative and qualitative data. This study's participants significantly improved on quantitative measures of depression, coping strategies, purpose in life, and post-traumatic growth at eight weeks post-intervention and follow-up. The qualitative content analysis revealed 17 themes with five essential themes. The program's activity to promote purpose in life through posttraumatic growth facilitated participants' recovery from traumatic experiences. Standardized guidelines are needed to conduct this program in Korean community centers.

Tamoxifen with ovarian function suppression versus tamoxifen alone as an adjuvant treatment for premenopausal breast cancer: a meta-analysis of published randomized controlled trials

Background Ovarian function suppression (OFS) significantly downregulates the concentration of plasma estrogens. However, it is unclear whether it offers any survival benefits if combined with adjuvant tamoxifen treatment in premenopausal women. This meta-analysis was designed to assess data from previous studies involving adjuvant tamoxifen treatment plus OFS in premenopausal breast cancer. Methods Electronic literature databases (PubMed, Embase, the Web of Science, and the Cochrane Library) were searched for relevant randomized controlled trials published prior to February 1, 2015. Only randomized controlled trials that compared tamoxifen alone with tamoxifen plus OFS for premenopausal women with breast cancer were selected. The evaluated endpoints were disease-free survival and overall survival. Results Four randomized controlled trials comprising 6,279 patients (OFS combination, n=3,133; tamoxifen alone, n=3,146) were included in the meta-analysis. There was no significant improvement in disease-free survival or overall survival with addition of OFS in either the whole population or the hormone receptor-positive subgroup. The risk of distant recurrence was not reduced with the addition of OFS in the whole population. A subgroup analysis showed that addition of OFS significantly improved overall survival in patients who were administered chemotherapy. Conclusion Based on the available studies, concurrent administration of OFS and adjuvant tamoxifen treatment for premenopausal women with breast cancer has no effect on prolonging disease-free survival and overall survival, excluding patients who were administered chemotherapy. It should not be widely recommended, except perhaps for women who were hormone-receptor positive and who were also administered adjuvant chemotherapy. PMID:26109867

Relationships between self-reported lifetime physical activity, estimates of current physical fitness, and aBMD in adult premenopausal women.

Osteoporosis is common, and physical activity is important in its prevention and treatment. Of the categories of historical physical activity (PA) examined, we found that weight-bearing and very hard physical activity had the strongest relationships with areal bone mineral density (aBMD) throughout growth and into adulthood, while for measures of strength, only grip strength proved to be an independent predictor of aBMD. To examine relationships between aBMD (total body, lumbar spine, proximal femur, tibial shaft, distal radius) and estimates of historical PA, current strength, and cardiovascular fitness in adult premenopausal women. One hundred fifty-two adult premenopausal women (40 ± 9.6 years) undertook aBMD (dual-energy X-ray absorptiometry (DXA)) and completed surveys to estimate historical physical activity representative of three decades (Kriska et al. [1]), while subsets underwent functional tests of isokinetic strength (hamstrings and quadriceps), grip strength (hand dynamometer), and maximum oxygen uptake (MaxV02; cycle ergometer). Historical PA was characterized by demand (metabolic equivalents, PA > 3 METS; PA > 7 METS) and type (weight-bearing; high impact). Significant positive independent predictors varied by decade and site, with weight-bearing exercise and PA > 3 METS significant for the tibial shaft (10-19 decade) and only PA > 7 METS significant for the final two decades (20-29 and 30-39 years; total body and total hip). A significant negative correlation between high impact activity and tibial shaft aBMD appeared for the final decade. For strength measures, only grip strength was an independent predictor (total body, total hip), while MaxV02 provided a significant independent prediction for the tibial shaft. Past PA > 7 METS was positively associated with aBMD, and such activity should probably constitute a relatively high proportion of all weekly PA to positively affect aBMD. The findings warrant more detailed investigations in a prospective

Objective: This research identifies social reinforcers within religious institutions associated with alcohol consumption among Korean women in California. Method: Data were drawn from telephone interviews with female adults (N = 591) selected from a random sampling of persons in California with Korean surnames during 2007. Approximately 70% of attempted interviews were completed, with 92% conducted in Korean. Respondents were asked about any lifetime drinking (yes/no), drinking rate (typical number of drinks consumed on drinking days among current drinkers), and messages discouraging “excessive drinking” from religious leaders or congregants. Bivariable and multivariable regressions were used for analysis. Results: Approximately 70.4% of women reported any lifetime drinking, and drinkers drank a mean (SD) of 1.10 (1.22) drinks on drinking days. About 30.8%reported about 30.8% reported any exposure to religious leaders' messages discouraging excessive drinking, and 28.2% reported any exposure to similar messages from congregants. Each congregant's message was statistically significantly associated with a 5.1% lower probability (odds ratio = 0.775, 95% confidence interval [CI]: 0.626, 0.959) of any lifetime drinking. Also, each congregant's message was associated with a 13.8% (B = -0.138; 95% CI: -0.306, 0.029) lower drinking rate, which was statistically significant after adjusting for covariates using a one-tailed test. Exposure to leaders' messages was not statistically significantly associated with any lifetime drinking or drinking rate. Conclusions: Social reinforcement in the form of religious messages may be one mechanism by which religious institutions influence drinking behaviors. For Korean women, messages from congregants had a unique impact beyond the traditional religiosity indicators. These social mechanisms provide public health interventionists with religious pathways to improve drinking behaviors. PMID:19895765

This study was done to assess the bone mineral density (BMD), biochemical bone turnover markers (BTMs), and factors associated with bone health in young Korean women. Participants were 1,298 women, ages 18-29, recruited in Korea. Measurements were BMD by calcaneus quantitative ultrasound, BTMs for Calcium, Phosphorus, Osteocalcin, and C-telopeptide cross-links (CTX), body composition by physical measurements, nutrients by food frequency questionnaire and psychosocial factors associated with bone health by self-report. The mean BMD (Z-score) was -0.94. 8.7% women had lower BMD (Z-score≤-2) and 14.3% women had higher BMD (Z-score≥0) than women of same age. BTMs were not significantly different between high-BMD (Z-score≥0) and low-BMD (Z-score<0) women. However, Osteocalcin and CTX were higher in women preferring caffeine intake, sedentary lifestyle and alcoholic drinks. Body composition and Calcium intake were significantly higher in high-BMD. Low-BMD women reported significantly higher susceptibility and barriers to exercise in health beliefs, lower bone health self-efficacy and promoting behaviors. Results of this study indicate that bone health of young Korean women is not good. Development of diverse strategies to intervene in factors such as exercise, nutrients, self-efficacy, health beliefs and behaviors, shown to be important, are needed to improve bone health.

Goserelin with chemotherapy to preserve ovarian function in pre-menopausal women with early breast cancer: menstruation and pregnancy outcomes.

Premature ovarian failure and infertility following chemotherapy in early breast cancer (EBC) are major concerns for young women. The role of gonadotrophin-releasing hormone (GnRH) agonists with chemotherapy in EBC in reducing the incidence of chemotherapy-induced early menopause remains uncertain, and long-term data on the recovery of fertility are sparse. We report an audit of our experience with the GnRH agonist, goserelin (Zoladex®), used with chemotherapy to preserve ovarian function and maintain fertility. Pre-menopausal women were given goserelin subcutaneously every 28 days during chemotherapy, starting 0-14 days before treatment. The main clinical end point was recovery of menstruation after chemotherapy. The other end points were rate of successful conception and median time to recovery of menses. About 84% of 125 women recovered menstruation with the median time to recovery of 6 months (1-43 months), including 76% of 71 patients aged over 35. Of the 42 patients who attempted pregnancy, 71% (n=30) managed to achieve pregnancies. At the time of analysis, there were 42 pregnancies and 30 healthy deliveries. The GnRH agonist, goserelin, given with chemotherapy for EBC is associated with a low risk of long-term chemotherapy-induced amenorrhoea and a high chance of pregnancy. Further randomised trials are needed.

BACKGROUND Adjuvant therapy with an aromatase inhibitor improves outcomes, as compared with tamoxifen, in postmenopausal women with hormone-receptor–positive breast cancer. METHODS In two phase 3 trials, we randomly assigned premenopausal women with hormone-receptor–positive early breast cancer to the aromatase inhibitor exemestane plus ovarian suppression or tamoxifen plus ovarian suppression for a period of 5 years. Suppression of ovarian estrogen production was achieved with the use of the gonadotropin-releasing-hormone agonist triptorelin, oophorectomy, or ovarian irradiation. The primary analysis combined data from 4690 patients in the two trials. RESULTS After a median follow-up of 68 months, disease-free survival at 5 years was 91.1% in the exemestane–ovarian suppression group and 87.3% in the tamoxifen–ovarian suppression group (hazard ratio for disease recurrence, second invasive cancer, or death, 0.72; 95% confidence interval [CI], 0.60 to 0.85; P<0.001). The rate of freedom from breast cancer at 5 years was 92.8% in the exemestane–ovarian suppression group, as compared with 88.8% in the tamoxifen–ovarian suppression group (hazard ratio for recurrence, 0.66; 95% CI, 0.55 to 0.80; P<0.001). With 194 deaths (4.1% of the patients), overall survival did not differ significantly between the two groups (hazard ratio for death in the exemestane–ovarian suppression group, 1.14; 95% CI, 0.86 to 1.51; P = 0.37). Selected adverse events of grade 3 or 4 were reported for 30.6% of the patients in the exemestane–ovarian suppression group and 29.4% of those in the tamoxifen–ovarian suppression group, with profiles similar to those for postmenopausal women. CONCLUSIONS In premenopausal women with hormone-receptor–positive early breast cancer, adjuvant treatment with exemestane plus ovarian suppression, as compared with tamoxifen plus ovarian suppression, significantly reduced recurrence.

Our specific aim was to determine whether coronary heart disease (CHD) risk factors in polycystic ovary syndrome (PCOS) patients were independent of their higher body mass index (BMI) and centripetal obesity. In adult, premenopausal, white women, CHD risk factors were compared between 488 patients with well-defined PCOS and 351 healthy free-living population controls from the Princeton Follow-up Study (PFS). After excluding women with irregular menses (putative PCOS phenotypes), comparisons were also made between the 261 PFS women with a history of regular menses and the 488 women with PCOS. Fasting lipids, insulin, glucose, homeostasis model assessment of insulin resistance (HOMA-IR), HOMA insulin secretion, blood pressure, BMI, and waist circumference were measured. Compared with both the full cohort of 351 PFS women and the subgroup of 261 PFS women with regular menses, women with PCOS had higher BMI, waist circumference, total and low-density lipoprotein cholesterol, triglyceride, systolic blood pressure, diastolic blood pressure, insulin, glucose, and HOMA-IR (all Ps < or = .005). After adjusting for age and BMI, women with PCOS, compared with the 351 and 261 PFS women, had lower high-density lipoprotein cholesterol (P < .0001, .0008) and higher systolic blood pressure (P = .0002, < .0001), insulin (P = .017, .039), HOMA-IR (P = .013, .032), and HOMA insulin secretion (P = .022, .037). The small subgroup of PCOS women with normal BMI (<25 kg/m(2)) (36/488, 7%) also had higher age-adjusted insulin, glucose, and HOMA-IR (all Ps < .005) than the subgroup of PFS women with BMI less than 25 kg/m(2) (123/261, 47%). Increased CHD risk factors and high HOMA-IR in PCOS cannot be exclusively attributed to their preponderant centripetal obesity. Identification of women with clinical features of PCOS should alert the clinician to potentially increased risk for CHD and prompt CHD risk factor testing.

Objective To determine the age specific serum anti-Müllerian hormone (AMH) reference values in Korean women with regular menstruation. Methods Between May, 2010 and January, 2011, the serum AMH levels were evaluated in a total of 1,298 women who have regular menstrual cycles aged between 20 and 50 years. Women were classified into 6 categories by age: 20-31 years, 32-34 years, 35-37 years, 38-40 years, 41-43 years, above 43 years. Measurement of serum AMH was measured by commercial enzyme-linked immunoassay. Results The serum AMH levels correlated negatively with age. The median AMH level of each age group was 4.20 ng/mL, 3.70 ng/mL, 2.60 ng/mL, 1.50 ng/mL, 1.30 ng/mL, and 0.60 ng/mL, respectively. The AMH values in the lower 5th percentile of each age group were 1.19 ng/mL, 0.60 ng/mL, 0.42 ng/mL, 0.27 ng/mL, 0.14 ng/mL, and 0.10 ng/mL, respectively. Conclusion This study determined reference values of serum AMH in Korean women with regular menstruation. These values can be applied to clinical evaluation and treatment of infertile women.

Background Low iron intake can lead to iron deficiency, which can result in impaired health and iron-deficiency anemia. A mobile phone app, combining successful dietary strategies to increase bioavailable iron with strategies for behavior change, such as goal setting, monitoring, feedback, and resources for knowledge acquisition, was developed with the aim to increase bioavailable iron intake in premenopausal women. Objective To evaluate the content, usability, and acceptability of a mobile phone app designed to improve intake of bioavailable dietary iron. Methods Women aged 18-50 years with an Android mobile phone were invited to participate. Over a 2-week period women were asked to interact with the app. Following this period, semistructured focus groups with participants were conducted. Focus groups were audio recorded and analyzed via an inductive open-coding method using the qualitative analysis software NVivo 10. Themes were identified and frequency of code occurrence was calculated. Results Four focus groups (n=26) were conducted (age range 19-36 years, mean 24.7, SD 5.2). Two themes about the app’s functionality were identified (frequency of occurrence in brackets): interface and design (134) and usability (86). Four themes about the app’s components were identified: goal tracker (121), facts (78), photo diary (40), and games (46). A number of suggestions to improve the interface and design of the app were provided and will inform the ongoing development of the app. Conclusions This research indicates that participants are interested in iron and their health and are willing to use an app utilizing behavior change strategies to increase intake of bioavailable iron. The inclusion of information about the link between diet and health, monitoring and tracking of the achievement of dietary goals, and weekly reviews of goals were also seen as valuable components of the app and should be considered in mobile health apps aimed at adult women.

The lipid accumulation product, a combination of waist circumference and triglycerides concentration, has been suggested as a better marker for abnormal glucose regulation than BMI. We aimed to compare the lipid accumulation product and BMI as useful markers for abnormal glucose regulation in young Korean women. The lipid accumulation product was calculated using the formula [waist circumference (cm) - 58] × triglycerides (mmol/l). Glucose tolerance status was determined using a 75-g oral glucose tolerance test in 2810 Korean women aged 18-39 years from the general population. The prevalence of abnormal glucose regulation was 6.8% (isolated impaired fasting glucose 1.8%, isolated impaired glucose tolerance 4.0%; impaired fasting glucose + impaired glucose tolerance 0.4% and diabetes mellitus 0.6%). According to the quintile distributions of the lipid accumulation product and BMI, women with a lipid accumulation product quintile greater than their BMI quintile exhibited significantly greater areas under the curve and higher levels of 2-h post-load glucose, insulin, homeostasis model analysis of insulin resistance and lipid profiles than did women with a BMI quintile greater than their lipid accumulation product quintile. Multiple logistic regression revealed that the lipid accumulation product exhibited a higher odds ratio for abnormal glucose regulation than did BMI after adjusting for age, systolic blood pressure, HDL cholesterol, previous history of gestational diabetes and family history of diabetes (odds ratios 3.5 and 2.6 of the highest vs. the lowest quintiles of lipid accumulation product and BMI, respectively). The lipid accumulation product could be useful for identifying the young Korean women with abnormal glucose regulation. © 2012 The Authors. Diabetic Medicine © 2012 Diabetes UK.

This study investigates the impact of reproductive factors on the association between education and breast cancer mortality in Belgium. The role of reproductive factors has been investigated in several studies, with mixed results. Reproductive factors are either completely or partially responsible for the association between education and breast cancer mortality. The data consist of the 1991 census linked to registration data on cause-specific mortality during the period 1991-1995, including all breast cancer deaths in Belgium during the observation period. The study population includes all women aged 35-79 at time of the census. Age-standardized mortality rates and mortality rate ratios (Poisson regression) are computed for educational groups with and without control for reproductive factors. The population is stratified according to age (women aged 35-49 and 50-79) and according to nulliparity. The relationship between education and breast cancer is significant among postmenopausal women. Breast cancer mortality is higher among the higher educated women. These results are consistent with international findings, the gradient not being negative as in most other causes of death, but positive. Statistical control for parity and age at first birth reduces the association largely. In addition, among nonparous women, differences in breast cancer mortality by education are not consistent and generally not significant. Reproductive factors are largely responsible for the positive association between education and breast cancer mortality among postmenopausal women in Belgium. Among premenopausal women, the relation is not significant, a pattern consistent with international studies. Copyright © 2012 UICC.

Background As coffee consumption is increasing remarkably over the past decade, the health effects concerning the coffee drinking has gained a wide attention across the nation. However, there is not a true consensus regarding the effects of coffee on metabolic disease. Therefore, this study aims to examine the association between coffee intake and the risk of metabolic syndrome in Korean women Methods We used publicly accessible datasets collected through Korean National Health and Nutrition Examination Survey (KNHANES). Among 20,435 individuals from five consecutive years’ worth of data from 2007 to 2011, only 15,691 subjects qualified for statistical analysis upon applying the exclusion criteria. We carried out the statistical analysis utilizing SPSS Statistics version 13.0 (IBM Corp., Armonk, NY.) and STATA statistical software release 13.0 (STATA Corp., College Station, TX). Results We found that the frequency of coffee intake inversely correlates with the prevalence of metabolic syndrome in women. Upon adjusting for life-style factors, socioeconomic status, and nutritional profile, the subjects from the highest coffee consumption quartile exhibited 40% lower odds of suffering from metabolic syndrome compared to those in the control (OR = 0.75; 95% CI = 0.67–0.84; P for trend < 0.001). Also, we observed that age- and BMI-adjusted HOMA-IR decreased as the coffee consumption increased (P for trend < 0.001). Conclusion The findings of our study suggest that coffee consumption might be associated with reduction of metabolic syndrome in Korean women. To elucidate this cross-sectional association between coffee consumption and metabolic syndrome in women, cohort studies are warranted to confirm this relationship. PMID:27977716

Korea has the highest suicide rate of developed countries, two times higher than the USA. Suicide trends among Koreans Americans living in the USA during the same period have not yet been described. We report suicide mortality rates and trends for four groups: (1) Korean Americans, (2) non-Hispanic White (NHW) Americans, (3) selected Asian American subgroups and (4) Koreans living in the Republic of Korea. We used US national (n = 18 113 585) and World Health Organization (WHO) (n = 232 919 253) mortality records for Korea from 2003 to 2012 to calculate suicide rates, all expressed per 100 000 persons. We assessed temporal trends and differences in age, gender and race/ethnicity using binomial regression. Suicide rates are highest in Koreans living in the Republic of Korea (32.4 for men and 14.8 for women). Suicide rates in Korean Americans (13.9 for men and 6.5 for women) have nearly doubled from 2003 to 2012 and exceed rates for all other Asian American subgroups (5.4-10.7 for men and 1.6-4.2 for women). Suicide rates among NHWs (21.0 for men and 5.6 for women) remain high. Among elders, suicide in Korean Americans (32.9 for men and 15.4 for women) is the highest of all examined racial/ethnic groups in the USA. Suicide in Korean Americans is higher than for other Asian Americans and follows temporal patterns more similar to Korea than the USA. Interventions to prevent suicide in Korean American populations, particularly among the elderly, are needed.

It is suggested that vitamin D level and age at menarche are related to each other, and the prevalence of low vitamin D status and early menarche in women is increasing worldwide. Moreover, several studies revealed that both of them are associated with metabolic syndrome (MetS). Therefore, we hypothesized that there are significant associations among vitamin D status, age at menarche, and MetS and that the relationships differ according to menstrual state. We assessed whether the association among MetS, vitamin D, and menarche age is different between premenopausal and postmenopausal women and whether there is a change in risk of MetS according to vitamin D level in different age-at-menarche groups. We used data from the Korea National Health and Nutrition Examination Survey, using 1:1 age-matching for this cross-sectional study. Individuals were stratified into 25-hydroxyvitamin D (25[OH]D) levels (deficient, <10 ng/mL; insufficient, 10-19 ng/mL; and sufficient, ≥20 ng/mL) and categorized as having either early, average, or late menarche (<13, 13-16, and ≥17 years). In premenopausal women, early menarche, not vitamin D level, was associated with risk of MetS (odds ratio [95% confidence interval], 1.65 [1.18-2.33]). In contrast, in postmenopausal women, vitamin D deficiency, not age at menarche, was associated with risk of MetS (1.39 [1.03-1.87]). In a stratified analysis regarding interactions of a change in risk of MetS according to vitamin D level in different ages at menarche, vitamin D deficiency was significantly associated with the risk of MetS (1.36 [1.01-1.86]), but this was only in the average-age-at-menarche group. This study suggests that the time of entry into puberty for women may be an important factor in the development of MetS in adulthood, and vitamin D status in women at average menarche age may contribute to the development of MetS.

The benefit of estrogen therapy in postmenopausal women is still uncertain. Based upon extensive observational data, it was believed that estrogen was cardioprotective. The relationship between the period of exposure to endogenous estrogens and the risk of cardiovascular disease (CVD) has not been studied in Korean women. To assess associations between reproductive lifespan and CVD by using the Framingham risk score (FRS) in postmenopausal Korean women. This cross-sectional, population-based study used data from the Korea National Health and Nutrition Examination Survey (KNHANES) for the five years 2008-2012,after adjustment for relevant variables using complex sample analysis and data weighting. Among 25,534 women, 1973 women were enrolled, after excluding those <20 or >80 years of age (n=6194), those with diabetes, CVD or cancer (n=491), those with unrecorded physical measurements (n=7335), those with menarche age ≤8 years or ≥20 years (n=6194), and premenopausal women (n=3347). The FRS tended to show a significant negative correlation with the reproductive lifespan (p<0.001). In multiple linear regression analysis, a negative correlation was observed between the reproductive lifespan and FRS (adjusted relative risk [RR] for <28 reproductive years [shortest lifespan group] compared with 28-33 reproductive years [moderate lifespan group], 1.2, p<0.001 and adjusted RR for >33 reproductive years [longest lifespan group] compared with 28-33 reproductive years [moderate lifespan group], -0.42, p=0.011). A longer reproductive lifespan is associated with a lower estimated risk of CVD in the next 10 years in postmenopausal women. This result suggests that estrogen has a long-term protective effect against CVD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

To examine the associations of various metabolites and hormones and hormone replacement therapy (HRT) with obesity. This is a cross-sectional study of 1326 Singaporean women. A DXA-derived percent body fat (PBF) of ≥35% and percent abdominal fat (PAbdF) of >21.8% were used, respectively, to define women with general (GOb) and abdominal (AbdOb) obesity. Higher levels of insulin and glucose, lower levels of HDL, higher levels of TC/HDL and HOMA values, and different levels of some hormones were noted only in the women with abdominal, and not general obesity. The incidence of general and abdominal obesity was higher in postmenopausal women with or without HRT, except that those who were on conjugated estradiol-only HRT had no increase in the incidence of general obesity compared with premenopausal women. Abdominal obesity is associated with insulin resistance and with higher risks of metabolic syndrome and cardiovascular diseases, whereas general obesity is not. Abdominal obesity may predispose to a higher risk of diabetes. The onset of the menopause tends to increase the incidence of general and abdominal obesity, except that postmenopausal women on conjugated estradiol HRT appear to be relatively protected from general obesity.

One of every four pregnant women in Chile is obese. Gestational obesity is associated with maternal metabolic complications in pregnancy (e.g., gestational diabetes, preeclampsia), but to our knowledge, there is little evidence on relationships with future metabolic risk. The aim of this study was to evaluate the association between prepregnancy obesity (prepregnancy body mass index ≥30 kg/m 2 ) or excessive gestational weight gain (GWG; according to the 2009 recommendations from the Institute of Medicine), and maternal metabolic complications 10 y postpartum in premenopausal Chilean women. A prospective study was conducted. In 2006, 1067 Chilean mothers of children born in 2002-participants of the GOCS (Growth and Obesity Cohort Study)-were recruited. Mothers completed a questionnaire concerning sociodemographic, anthropometric, and pregnancy characteristics. Of the sample, 402 women were randomly selected to participate in a study related to the determinants of breast cancer risk in 2012. At follow-up, anthropometry, blood pressure, and fasting labs were measured. Complete data was available for 366 women. Thirty-two percent of mothers had prepregnancy overweight/obesity and 39.1% had excessive GWG. In adjusted models, prepregnancy obesity was positively associated with increased insulin resistance (odds ratio [OR], 18; 95% confidence interval [CI], 5.2-62.7), metabolic syndrome (OR, 3.3; 95% CI, 1.3-8.3), and hyperglycemia (OR, 3; 95% CI, 1.1-8.6). Prepregnancy overweight/obesity was associated with increased risk for insulin resistance, metabolic syndrome, abdominal obesity, low high-density lipoprotein cholesterol, and hypertriglyceridemia (P < 0.05). Excessive GWG was not associated with metabolic risk in the main model but was found to be positively associated in models with correction of weight by possible recall bias. Gestational obesity was associated with maternal metabolic alterations 10 y postpartum. Prevention strategies for chronic diseases

Although research that takes into account partner and relationship factors in dyspareunia is slowly emerging, little is known about how these couples communicate about their sexuality. Additionally, partner psychosexual adjustment has not been examined in a controlled fashion. This study aimed to compare dyadic sexual communication, dyadic adjustment, psychological adjustment, and sexual well-being of women with self-reported dyspareunia and their partners with those of pain-free control women and their partners. Premenopausal women (n = 38; mean [M] age = 24.92) with self-reported dyspareunia, their partners (n = 38; M age = 26.71), as well as pain-free control women (n = 44; M age = 25.86) and their partners (n = 44; M age = 27.95) completed an online survey measuring dyadic sexual communication, dyadic adjustment, anxiety, depression, sexual functioning, and sexual distress. Assessments of women and men's (i) dyadic sexual communication; (ii) dyadic adjustment; (iii) anxiety; (iv) depression; (v) sexual functioning; and (vi) women's sexual distress were the main outcome measures. Compared with pain-free controls, women with dyspareunia reported significantly poorer dyadic sexual communication, a difference not found between partners of women with dyspareunia and control partners. Compared with partners of control women, those of women with dyspareunia reported significantly more impaired sexual functioning. No differences in dyadic adjustment were found between women with dyspareunia and pain-free control women, or between their respective partners. Finally, compared with control women, those with dyspareunia reported significantly more impaired psychological and sexual well-being. Findings suggest that dyspareunia impacts not only the psychosexual adjustment of affected women but also that of their partners. It seems relevant to include both members of the couple in future research and treatment for dyspareunia. © 2014

Depression among minority older adults is a prevalent underrecognized medical illness. Changes in cultural norms and social conditions because of immigration have a significant influence on mental health. The purpose of this study was to assess the interrelationships between acculturation, geographical location, gender, and depressive symptoms in community-dwelling elderly Korean immigrants and elderly Koreans. In this cross-sectional study, a convenience sample of 88 elderly Korean immigrants and 295 elderly Koreans was recruited separately from senior centers and senior apartments. Depressive symptoms were assessed with the Korean Geriatric Depression Scale-Short Form and acculturation with years of living in the United States. Acculturation had no significant relationship with depressive symptoms (r = 0.01, p = 0.94). Depressive symptoms were highly present in both elderly Korean immigrants and elderly Koreans. The prevalence of depressive symptoms was higher in women. This study provides baseline data for development of culturally specific, community-based intervention programs for better management of mental health of elderly Korean immigrants.

The purpose of this study was to assess and quantify the health outcomes associated with a moderate-intensity (50% VO2R) exercise program designed to achieve the American College of Sports Medicine net caloric expenditure guideline of 1,000 kcal x wk(-1). Fifteen apparently healthy but sedentary premenopausal women with the baseline characteristics (mean +/- SD age, height, weight, body composition, and VO2max: 37.4 +/- 6.3 yr, 166.2 +/- 6.2 cm, 72.1 +/- 11.2 kg, 32.5 +/- 5.8%, and 34.8 +/- 5.8 mL x kg(-1) x min(-1), respectively) participated in and completed the study. Exercise training was performed 3-4 days per week for 10 weeks in a progressive manner at moderate intensity (50% VO2R). There were significant (P < 0.05) improvements in VO2max (+2.5 mL x kg(-1) x min(-1)), systolic (-13.7 mm Hg) and diastolic (-6.4 mm Hg) blood pressure, high-density lipoprotein cholesterol (+3.2 mg x dL(-1)), fasting blood glucose (-4.9 mg x dL(-1)), and percent body fat (-1.6%). Although the American College of Sports Medicine specifies that the energy expenditure goal should be a net caloric expenditure of 1,000 kcal x wk(-1) and classifies relative moderate intensity as 40-59% of heart rate reserve or VO2R, we are unaware of any previous investigations that have examined the specific health outcomes associated with an exercise program fulfilling these requirements. Results indicate that significant health benefits will be conferred to previously sedentary, premenopausal women who engage in a moderate-intensity, 10-week exercise program designed to fulfill the net energy expenditure guideline of 1,000 kcal x wk(-1).

The aim of this study was to identify the relationship between awareness of nutrition labeling and menstrual cycle irregularity in women from a nationally representative sample of the Korean population. A cross-sectional analysis was performed using hierarchical multivariable logistic regression analysis models. A total of 4,324 women aged 19~54 years from the 2010~2012 Korean National Health and Nutrition Examination Survey participated in the study. The participants were classified into three groups based on self-report responses to a questionnaire about their awareness of nutrition labels: Reading, Not-Reading, and Not-Knowing Groups. The Reading, Not-Reading, and Not-Knowing Groups comprised 46.4%, 44.9%, and 8.7% of the participants, respectively, and 53.6% of the participants had never used nutrition labels. In the Not-Knowing Group, irregular menstrual cycles for more than 3 months were significantly more common than women with irregular menstrual cycles for up to 3 months and women with regular menstrual cycles. Women in the Not-Knowing Group were more likely to exhibit menstrual cycle irregularity (adjusted odds ratio: 1.63, 95% confidence interval: 1.10~2.41) compared to women in the Reading Group after adjusting for age, body mass index, smoking status, alcohol intake, exercise regularity, stress, depression, suicidal ideation, metabolic syndrome, age at menarche, parity, and use of oral contraceptives. No awareness of nutrition labeling appears to be associated with a higher prevalence of menstrual cycle irregularity in a nationally representative group of Korean women. © 2017 Korean Society of Nursing Science

Mental stress is thought to underlie cardiovascular events, but there is information on oxidative stress induced by mental stress in association with cardiovascular responses in women. Using a sensitive assay for plasma 4-hydroxy-2-nonenal (HNE), as a marker for oxidative stress, we addressed the relation between pressor responses and oxidative stress induced by mental or physical stress in premenopausal and postmenopausal women. Healthy subjects (7 postmenopausal and 8 premenopausal women, in early and late follicular phases) were subjected to mental and physical stress evoked by a Color Word Test (CWT) and isometric handgrip, respectively. The CWT induced a rapid elevation of diastolic blood pressure (DBP), at a higher level in the postmenopausal than in the premenopausal women (p<0.01), and this higher DBP was sustained during the CWT and recovery (p<0.01). The CWT induced a significant elevation in plasma noradrenaline in premenopausal women in the early follicular phase and in postmenopausal women (p<0.05). Plasma nitric oxide metabolites were higher in postmenopausal than in the premenopausal women in the late follicular phase (p<0.05), but did not change during exposure to the two types of stress in either group. Plasma HNE was increased during recovery from the CWT, but not the handgrip, in postmenopausal women (2.4 times, p<0.05). There was a significant difference in the time course of the CWT-induced HNE response between the postmenopausal and premenopausal women (p<0.05). These findings suggest that mental, but not physical, stress causes sustained diastolic blood pressure elevation in postmenopausal women, accompanied by heightened oxidative stress.

The Korean National Cancer Screening Survey (KNCSS), a nationwide cross-sectional survey, has been conducted annually since 2004. The current study was conducted to report on the trends in screening rates among Korean men and women, and to evaluate policies regarding cancer screening programs implemented to reduce the burden of cancer. The current study used KNCSS data. The eligible study population included men aged 40-74 years and women aged 30-74 years with no cancer history. The lifetime screening rate, screening rate with recommendation, and changes in annual rates were calculated for five major cancers (i.e., stomach, liver, colorectal, breast, and cervix uteri). The screening rates with recommendation increased by 4.2% (95% confidence interval [CI], 3.7% to 4.8%) annually for stomach cancer, 1.2% (95% CI, 0.1% to 2.4%) for liver cancer, 3.0% (95% CI, 1.8% to 4.1%) for colorectal cancer, 3.7% (95% CI, 2.7% to 4.8%) for breast cancer, and 1.3% (95% CI, 0.8% to 1.8%) for cervical cancer. In 2013, the screening rates with recommendation for stomach, liver, colorectal, breast, and cervical cancers were 73.6%, 33.6%, 55.6%, 59.7%, and 67.0%, respectively. Both the lifetime screening rates and screening rates with recommendation for the five above-mentioned cancers increased annually from 2004 to 2013.

Our aim was to translate and cross-culturally adapt the fibromyalgia impact questionnaire into Korean (KFIQ), and then evaluate its reliability and validity. The FIQ was translated into Korean by three translators and then independently translated back into English by three different translators. A total of 62 women patients with fibromyalgia (FM) were studied for the psychometric properties of the KFIQ. The mean age of the patients was 47.1 (25-73) years, and all were female. The mean KFIQ score was 48.3 (17-91), and the mean Korean health assessment questionnaire (KHAQ) score was 0.4 (0-1.7). The test-retest reliability of the KFIQ yielded an intraclass correlation coefficient of 0.85 (0.53-0.96). For the construct validity, the Spearman rank correlations of KFIQ with patient global assessments using visual analog scale (pain, 0.58; morning stiffness, 0.45; fatigue, 0.48; depression, 0.43; anxiety, 0.56; global well-being, 0.46; disease severity, 0.49; impact on life, 0.51), KHAQ (0.44), and tender points (0.60) were high and statistically significant. The KFIQ might be a reliable and valid instrument for measuring health status and physical functioning in Korean women patients with FM, but needs further study.

We examined the association between the metabolic syndrome and cancer mortality in Koreans. This study included 42 336 men and 32 168 women aged > or =20 years who took health examination and were followed up for 5.6 years. Mortality data were analyzed according to the metabolic syndrome. The relative risk (RR) and 95% confidence interval (CI) of cancer mortality in subjects with metabolic syndrome compared with subjects without metabolic syndrome was 1.41 (1.08-1.84) after adjustment for possible confounding factors. The association is significant only among men [RR 1.52 (1.10-2.10)], but not among women. The RRs and 95% CIs for cancer deaths in subjects with elevated body mass index, blood pressure, fasting glucose, and triglycerides were 1.36 (1.07-1.71), 1.34 (1.07-1.69), 1.45 (1.14-1.86), and 1.60 (1.26-2.02) after mutual adjustment, respectively. Upon increasing the number of metabolic risk factors to 1, 2-3, and 4-5, the RRs and 95% CIs of death from cancer were 1.32 (0.83-1.48), 1.47 (1.10-1.96), and 2.42 (1.25-4.68), respectively, with a graded fashion (P for trend < 0.005). Our results indicate that metabolic syndrome is a risk factor for cancer-related death in Korean adults. Prevention and management of the metabolic syndrome would be needed to reduce cancer mortality.

Korean American women have among the lowest rates of cervical cancer screening in the United States. The authors evaluated a multicomponent intervention combining community education with navigation services to reduce access barriers and increase screening rates in this underserved population. It was hypothesized that cervical cancer screening rates would be higher among women who received the intervention program compared with those in the control program. Korean American women (N = 705) were recruited from 22 churches. In this matched-pair, group-randomized design, 347 women received the intervention, which consisted of a culturally relevant cancer education program combined with provision of navigation services. The control group (N = 358) received general health education, including information about cervical cancer risk and screening and where to obtain low-cost or no-cost screening. Screening behavior was assessed 12 months after the program. Screening behavior data were obtained from 588 women 12 months after the program. In both site-level and participant-level analyses, the intervention program contributed to significantly higher screening rates compared with the control program (odds ratio [OR], 25.9; 95% confidence interval [CI], 10.1-66.1; P < .001). In sensitivity analysis, the treatment effect remained highly significant (OR, 16.7; 95% CI, 8.1-34.4; P < .001). A multicomponent intervention combining community cancer education with navigation services yielded significant increases in cervical cancer screening rates among underscreened Korean American women. Community-accessible programs that incorporate cancer education with the delivery of key navigation services can be highly effective in increasing cervical cancer screening rates in this underserved population.

The menopausal transition is characterized by increased body fat accumulation, including redistribution from peripheral to central fat depots. This distribution is associated with an increased risk of type 2 diabetes and cardiovascular disease that are linked to low-grade inflammation. We determined whether postmenopausal women have higher levels of inflammatory markers, compared with premenopausal women. We also wanted to determine whether these markers are reduced by stable weight loss in obese women. Anthropometric data, blood samples and subcutaneous adipose tissue biopsies were collected from normal weight premenopausal and postmenopausal women and obese women before and 2 years after gastric bypass (GBP) surgery. Serum protein levels and adipose tissue gene expression of inflammatory markers were investigated. IL-8 expression in adipose tissue and circulating levels were higher in postmenopausal vs premenopausal women. IL-8 expression was associated with waist circumference, independent of menopausal status. IL-6 expression and serum levels of monocyte chemoattractant protein (MCP)-1 were higher in postmenopausal vs premenopausal women. Two years after GBP surgery, adipose expression of IL-8, tumour necrosis factor-α and MCP-1 decreased significantly. Serum insulin levels were associated with inflammation-related gene expression before GBP surgery, but these associations disappeared after surgery. Postmenopausal women have an increased inflammatory response in the subcutaneous fat and circulation. Inflammatory markers in adipose tissue decreased significantly after surgery-induced weight loss. This effect may be beneficial for metabolic control and reduced cardiovascular risk after weight loss. © 2011 Blackwell Publishing Ltd.

Few studies have examined overall patterns of eating alone in relation to the risk of metabolic syndrome (MetS) in Korean populations. The present study aimed to examine the relationship between patterns of eating alone and the risk of MetS in Korean adults. Data from the Korea National Health and Nutrition Examination Survey (KNHANES) for 2013⁻2015 were used, with 8988 Korean adult participants, including 3624 men and 5364 women, aged 18 to 64 years. Patterns of eating alone were categorized into eight groups based on the total frequency of eating alone on a daily basis in the past one year: (1) three times for breakfast, lunch, and dinner; (2) twice for breakfast and dinner; (3) twice for lunch and dinner; (4) twice for breakfast and lunch; (5) once for breakfast only; (6) once for lunch only; (7) once for dinner only; and (8) never eating alone. The presence of MetS has been defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) and International Diabetes Federation (IDF). Multivariable logistic regression analyses were performed to assess the association between patterns of eating alone versus the risk of MetS after controlling for age, income, occupation, number of family members, generation types, marital status, smoking status, and physical activity. The prevalence of MetS was the highest in men and women aged 40⁻64 who had breakfast, lunch, and dinner alone (50.1% and 36.8%, respectively). Men who had dinner alone or lunch and dinner alone compared with those who eat with others had a significantly higher risk of MetS, with adjusted odds ratios (AOR) of 1.51, and a 95% confidence interval (CI) of 1.06⁻2.16; and an AOR of 1.54, with a 95% CI of 1.05⁻2.25, respectively. Women who had breakfast alone compared with those who ate with others had a significantly lower risk of MetS (AOR 0.70, 95% CI 0.53⁻0.94). In conclusion, patterns of eating alone are differentially associated with the risk of MetS in a

How Menopause Symptoms and Attitude Impact Korean Women's Quality of Life After Adjuvant Treatment for Breast Cancer.

PubMed

Attitudes toward menopause vary across cultures and influence women's experiences of menopausal symptoms, possibly leading to reduced posttreatment quality of life in breast cancer survivors. The aim of this study is to examine the effects of menopausal symptoms and attitudes on health-related quality of life in breast cancer survivors who were premenopausal at the time of diagnosis. A total of 139 women receiving chemotherapy with/without endocrine therapy were assessed with self-report questionnaires of established reliability and validity. Hierarchical regression was conducted to assess the impact of menopausal symptoms and attitudes on quality of life, while controlling for demographic characteristics. Overall, participants endorsed more than half of 46 symptoms, most at the level of mild symptoms, and most reported a less positive attitude toward menopause. Lower quality of life was significantly predicted by more menopausal symptoms endorsed and more negative attitudes when controlling for demographic factors associated with quality of life (R = 26.1%). Most participants experienced change from premenopause to postmenopause after the completion of adjuvant chemotherapy with or without tamoxifen. The results suggest that more menopausal symptoms and negative attitudes toward menopause may affect health-related quality of life considerably in chemotherapy-treated Asian breast cancer survivors. Healthcare professionals should develop a better understanding of the effects of menopausal symptoms and attitudes on quality of life by using a culturally relevant perspective based on patients' sociocultural backgrounds. Furthermore, these findings help healthcare professionals communicate with their Asian clients in a more informed way and provide culturally appropriate and individualized care.

Uric Acid Level Has a J-Shaped Association with Arterial Stiffness in Korean Postmenopausal Women.

Uric acid has been reported to function both as an oxidant or antioxidant depending on the context. A previous study in the Korean population reported a positive linear association between serum uric acid level and arterial stiffness in men, but little is known about how serum uric acid level is related to the risk of increased arterial stiffness in Korean postmenopausal women. We performed a cross-sectional study of 293 subjects who participated in a health examination program run by the health promotion center of Gangnam Severance Hospital between October 2007 and July 2010. High brachial-ankle pulse wave velocity was defined as a brachial-ankle pulse wave velocity of more than 1,450 cm/s. The odds ratios (ORs) for high brachial-ankle pulse wave velocity were calculated using multivariate logistic regression analysis across uric acid quartiles after adjusting for other indicators of cardiovascular risk. The 293 postmenopausal women were divided into quartiles according to uric acid level. The mean brachial-ankle pulse wave velocity values of each quartile were as follows: Q1, 1,474 cm/s; Q2, 1,375 cm/s; Q3, 1,422 cm/s; Q4, 1,528 cm/s. The second quartile was designated as the control group based on mean brachial-ankle pulse wave velocity value. Multivariate adjusted ORs (95% confidence intervals) for brachial-ankle pulse wave velocity across the uric acid quartiles were 2.642 (Q1, 1.095-6.3373), 1.00, 4.305 (Q3, 1.798-10.307), and 4.375 (Q4, 1.923-9.949), after adjusting for confounding variables. Serum uric acid level has a J-shaped association with arterial stiffness in Korean postmenopausal women.

Few studies have compared health behaviors of Koreans in their home country and Korean Americans. Using 2009 data from the Community Health Survey (South Korea) and the California Health Interview Survey (USA), we compared native Koreans and Korean Americans, grouped by level of acculturation, on prevalence of specific health behaviors and self-rated health, and conducted multiple logistic regression comparing the odds of these behaviors among the groups adjusted for demographic variables. While Korean Americans exhibit healthier behaviors than Koreans in some areas (e.g., reduced smoking and binge drinking in men, increased utilization of flu vaccinations), we also identified problem behaviors (e.g., increased body weight in Korean American men, uptake of alcohol drinking and smoking among Korean American women). Findings support the critical need for health promotion programs addressing these health behaviors to prevent future health problems among Korean Americans.

To explore the association between resilience and psychosocial variables of theoretical relevance such as self-esteem, optimism, religiousness, cultural interdependency, and belief in higher education in a population of elderly Korean women and their daughters who experienced great adversity. Surveys were conducted with 200 elderly Korean women and 170 of their daughters in several community locations. Both mothers and daughters experienced great adversities in their lives such as psychological and physical losses from war as well as current and past difficulties with relocation. The mothers' bivariate correlations indicate that self-esteem, optimism, religiousness, and cultural interdependency were significantly correlated with resilience. Length of time in the US, age entering the US, physical and psychological war-related adversities, current relocation difficulties, self-esteem, optimism, cultural interdependency, and belief in education were all significantly associated with daughters' resilience. In linear regression, self-esteem and optimism were significant predictors of resilience in both mothers and daughters. Self-esteem and optimism deserve further attention as psychological factors that may increase the likelihood of developing resilience. Implications of these findings for health professionals are discussed.

To investigate the possible association between primary ovarian insufficiency (POI) and TNF-α gene polymorphisms in Korean women. Case-control study. An urban university-based hospital in South Korea. A cohort of 135 Korean POI patients and 236 controls. None. We analyzed TNF-α gene variants of all participants using the polymerase chain reaction-restriction fragment length polymorphism assay. The TNF-α -1031TC+CC, -238GA+AA, -1031TC+CC/-308GG, -1031TT/-308GA+AA, -1031TC+CC/-238GA+AA, and -308GG/-238GA+AA genotypes were significantly more frequent in POI patients than in controls. Among the haplotypes for the three TNF-α loci, the -1031C/-308G/-238A haplotype was more frequent in POI patients than in controls and conferred POI susceptibility. In analyses of two loci, the -1031T/-308A, -1031C/-308G, -1031C/-238A, and -308G/-238A haplotypes were more frequent in POI patients. The TNF-α -1031C and -238A alleles had strong association with POI. The TNF-α -308A allele showed limited significance for POI risk with the presence of the -1031T allele. Our data suggest that the minor alleles of TNF-α promoter polymorphisms may increase POI risk in Korean women. Copyright © 2012 American Society for Reproductive Medicine. Published by Elsevier Inc.

Abstract Background Metabolic endotoxemia is associated with obesity and contributes to postprandial inflammation. Objective We aimed to determine if low-fat yogurt consumption prevents postprandial inflammation and dysmetabolism in healthy women by inhibiting biomarkers of metabolic endotoxemia. Methods Premenopausal women defined as obese and nonobese [body mass index (BMI, in kg/m2) 30–40 and 18.5–27, respectively, n = 120] were randomly assigned to consume 339 g of low-fat yogurt (YN, yogurt nonobese; YO, yogurt obese) or 324 g of soy pudding (CN, control nonobese; CO, control obese) for 9 wk (n = 30/group). The intervention foods each supplied 330 kcal with 3 g fat, 66 g carbohydrate, and 4–6 g protein. At weeks 0 and 9, participants ingested 226 g of yogurt or 216 g of soy pudding before a meal providing 56–60 g fat, 82 g carbohydrate, and 28–30 g protein. Plasma soluble CD14 (sCD14), lipopolysaccharide-binding protein (LBP), LPS activity, interleukin-6 (IL-6), glucose, triglyceride, and insulin were measured hourly for 4 h to assess differences in postprandial responses between groups by 2-factor ANOVA. Results Premeal yogurt consumption prevented the postprandial decrease in sCD14 net incremental area under the curve (net iAUC) by 72% in obese individuals at week 0 (P = 0.0323). YN and YO had ≥40% lower net iAUC of LBP-to-sCD14 ratio and plasma IL-6 concentration than CN and CO, respectively (P < 0.05). CO had postprandial hyperglycemia which was not evident in YO; in contrast YN had 57% less postprandial hypoglycemia than did CN (P-interaction = 0.0013). After 9 wk of yogurt consumption, ΔAUC of LBP-to-sCD14 ratios of YO and YN were less than half of those of the control groups (P = 0.0093). Conclusion Yogurt consumption improved postprandial metabolism and biomarkers of metabolic endotoxemia in healthy premenopausal women. Premeal yogurt consumption is a feasible strategy to inhibit postprandial dysmetabolism and thus

To examine the relationship between cancer-related fatigue (CRF) and physical activity in daily living in premenopausal disease-free cervical and endometrial cancer survivors. A physical activity monitor was used to collect objective data on daily physical activity. CRF and related variables were measured using self-report scales in a cross-sectional manner. The average age was 44.9 years among 64 women. The higher CRF group comprised 22 women (34%), 10% of whom had severe fatigue. The participants had higher physical activity levels compared with the findings in previous studies, and reported an average of 40 min/day of moderate to vigorous activity. Moderate to vigorous levels of physical activity were derived from essential social activities rather than leisure time exercise. There were no significant differences in physical activity levels between the lower and higher CRF groups. Our study results suggested that the higher level of physical activity in daily living itself had no relationship with decreasing CRF among premenopausal cervical and endometrial cancer survivors. It would be better to focus on cognitive and psychological factors before introducing physical activity programs and be careful of the characteristics of the participants' physical activity among this population in daily basis.

Pretest probability (PTP) and an exercise treadmill test (ETT) are recommended for the initial evaluation of possible coronary artery disease (CAD), but the applicability of these tests in Korean women has not been evaluated. Korean women with PTP, ETT, and invasive coronary angiography results were enrolled. Across all PTP levels, PTP and ETT statistics were evaluated and independent CAD predictors obtained. Of the 335 patients (mean age 58.0 ± 10.2 years), 99 and 236 were in the low (LPTP) and intermediate PTP (IPTP) groups, respectively. The observed prevalence of CAD was significantly lower than the PTP. (7.1% vs. 9.1 ± 4.9% in LPTP, p < 0.001; 23.3% vs. 33.0 ± 15.1% in IPTP, p < 0.001) The ETT's sensitivity and positive predictive values (PPVs) appeared lower than previously reported (LPTP: 42.9% and 16.7%; IPTP: 61.8% and 37.0%), whereas the negative predictive values (NPVs) were higher (LPTP: 95.1%; IPTP: 85.4%). After multivariate adjustments, positive ETT (odds ratio 3.276, 95% confidence interval 1.643-6.532, p = 0.001) independently predicted the presence of CAD, but the PTP showed only marginal predictability (odds ratio 1.019, 95% confidence interval 0.998-1.041, p = 0.069). In Korean women, the observed prevalence of CAD was lower than the PTP, and PTP showed only marginal CAD predictability. Although a positive ETT independently predicted CAD, the ETT showed lower sensitivity and PPVs than previously reported. Despite the limited value of PTP and ETT, the high NPVs of ETT appear useful for saving patients from unnecessary further examinations.

Little is known about longitudinal associations of exercise with different types of cancer, particularly in Asian populations. The purpose of this research was to estimate the association between the duration of exercise and all-cause and cancer-specific mortality. Data were obtained from the Korean Metabolic Syndrome Mortality Study (KMSMS), a prospective cohort study of 303,428 Korean adults aged 20 years or older at baseline between 1994 and 2004 after exclusion of individuals with missing variables on smoking and exercise. Death certificate-linked data until 31 December 2015 were provided by the Korean National Statistical Office. Cox regression models were constructed to evaluate the associations of exercise with cancer mortality after adjusting for potential confounders such as age, alcohol consumption and smoking status. During the follow-up period of 15.3 years (4,638,863 person-years), a total of 16,884 participants died. Both men and women who exercised showed approximately 30% decreased hazards of mortality, compared to those who did no exercise (hazard ratio (HR) 0.70, 95% confidence interval (CI)=0.68-0.73 for men, HR=0.71, CI : 0.67-0.75). A notable observation of this study is the curvilinear associations between the total duration of exercise per week and cancer mortality, with the lowest risk being observed at the low-to-medium levels of exercise; this trend of associations was found for esophagus, liver, lung, and colorectal cancer mortality in men, and all-cause, all-cancer and lung cancer mortality in women. Individuals who exercised showed considerably lower all-cause and cancer mortality risks compared with those who did no exercise. Policies and clinical trials aimed at promoting minimal or moderate participation in exercise may minimize cancer mortality risk.

PubMed

Park, Sunah; Yeoum, SoonGyo; Kim, Yoonjung; Kwon, Hye Jin

The purpose of this study was to explore the self-management experiences of Korean women with urinary incontinence (UI). Descriptive, qualitative study using focus groups. Twenty-two community-dwelling women, 65 years and older, participated in 3 focus-group interviews. Participants were recruited from 2 elderly halls and 1 senior welfare center in South Korea. Three focus group interviews comprising 6 to 8 individuals were conducted in a quiet venue at the elderly hall or senior welfare center. Two investigators performed the interviews; one acted as moderator and one as notetaker; interviews began with scripted open-ended questions. All interviews were electronically recorded and transcribed verbatim. Using an inductive thematic approach, data were first analyzed by the first and second authors; and all 4 authors contributed to coding and agreed on final themes. Korean women perceived UI as a loss of dignity, an odor problem, an uncontrollable disease, and a life impairment. Thematic analysis revealed 4 themes regarding the self-management experience of UI: preserving self-respect in the sociocultural environment, deodorizing the smell, keeping the secret of uncontrollability, and adjusting to an impaired life. Women in this study used various daily-living strategies to manage UI, but they mainly implemented strategies to keep UI a secret, including restrictions in activities of daily living. Educational approaches are needed to inform women with UI about more effective management skills.

The purpose of the current study was to examine factors that influence rape myths among Korean college students. This study was particularly interested in the ways in which attitudes toward women and sexual double standard affect the relationship between gender and rape myths. Although the incidence of rape is a common concern in many current societies, within each society, the specific components of rape myths reflect the cultural values and norms of that particular society. A sample of 327 college students in South Korea completed the Korean Rape Myth Acceptance Scale-Revised, the Attitudes Toward Women Scale, and the Sexual Double Standard Scale. Structural equation modeling (SEM) was used to test hypothesized models. Results revealed that in three of the four models, rape survivor myths, rape perpetrator myths, and myths about the impact of rape, attitudes toward women were a more important predictor of rape myths than gender or sexual double standard. In the rape spontaneity myths model, on the other hand, sexual double standard was a more important predictor than gender or attitudes toward women. This study provides valuable information that can be useful in developing culturally specific rape prevention and victim intervention programs.

Reduced-calorie diets are difficult to follow because they often require elimination of certain foods, leading to poor compliance and limited success. However, a low-calorie, nutrient-dense diet has the potential to accommodate a daily snack without exceeding energy requirements, even during weight loss. This pilot study evaluated the effects of a reduced-calorie diet including either a daily dark chocolate snack or a non-chocolate snack on anthropometric and body composition measurements. In a randomized clinical trial, 26 overweight and obese (body mass index ≥25 to ≤43) premenopausal women were assigned to a reduced-calorie diet that included either a daily dark chocolate snack or non-chocolate snack (n=13 per group) for 18 weeks. At baseline and end of study, body weight and waist and hip circumferences were measured along with fat mass, lean mass, and body fat percentage by dual-energy x-ray absorptiometry. Energy and macronutrient intakes were estimated from 4-day food records. Within- and between-group changes from baseline were analyzed using paired t tests and independent t tests, respectively. Women in both snack groups reduced estimated daily energy intake (P<0.001). Women in both the dark chocolate snack and non-chocolate snack groups, respectively, experienced decreases (P<0.001) in body weight (-5.1 vs -5.1 kg), hip circumference (-5.8 vs -5.4 cm), waist circumference (-5.7 vs -3.5 cm), fat mass (-3.9 vs -3.6 kg), and body fat percentage (-3.4% vs -3.1%), with no change in lean mass. Improvements in anthropometric and body composition measurements among overweight and obese premenopausal women can be achieved with a reduced-calorie diet including either a daily dark chocolate snack or non-chocolate snack.

Validation of the Korean Version of the Breast Cancer Screening Beliefs Questionnaire.

PubMed

Kwok, Cannas; Lee, Mi-Joung; Lee, Chun Fan

Korean immigrant women have been consistently reported as having low participation in breast cancer screening practices. A valid and reliable instrument to explore factors that affect their cancer screening behaviors is essential. The aim of this study was to report the psychometric properties of the Korean version of the Breast Cancer Screening Beliefs Questionnaire (BCSBQ). A convenience sample of 249 Korean Australian women was recruited through a number of Korean community organizations in Sydney. Exploratory factor analysis supports a similar fit for the original 3-factor structure of our data set. A significant association was found between the attitudes of these women toward general health checkups and the frequency of their performance of the breast awareness practices and having mammograms. Furthermore, it was found that knowledge and perceptions about the breast cancer scales were significantly associated with education level and that barriers to mammographic screening were much less evident among women who engaged in the 3 screening practices. The results indicated that the Korean version of the BCSBQ had satisfactory validity and internal consistency. The Cronbach's α of the 3 subscales ranged between .80 and .88. The Korean version of the BCSBQ was confirmed to be a culturally appropriate, valid, and reliable instrument for assessing the beliefs, knowledge, and attitudes to breast cancer and breast cancer screening practices among women of Korean background living in Australia. The Korean version of the BCBSQ can provide nurses with insights into the development of culturally sensitive breast health education programs.

Essentials It is unknown how regular exercise affects platelet function after menopause. We studied the effect of 3-months of high-intensity exercise in pre- and postmenopausal women. Platelet sensitivity to the inhibitory effect of arterially infused prostacyclin was increased. Reduced basal platelet reactivity was seen in the premenopausal women only. Background The risk of atherothrombotic events increases after the menopause. Regular physical activity has been shown to reduce platelet reactivity in younger women, but it is unknown how regular exercise affects platelet function after the menopause. Objectives To examine the effects of regular aerobic exercise in late premenopausal and recent postmenopausal women by testing basal platelet reactivity and platelet sensitivity to prostacyclin and nitric oxide. Methods Twenty-five sedentary, but healthy, late premenopausal and 24 matched recently postmenopausal women, mean (95% confidence interval) 49.1 (48.2-49.9) and 53.7 (52.5-55.0) years old, participated in an intervention study: 3-month high-intensity supervised aerobic spinning-cycle training (1 h, × 3/week). Basal platelet reactivity was analyzed in platelet-rich plasma from venous blood as agonist-induced % aggregation. In a subgroup of 13 premenopausal and 14 postmenopausal women, platelet reactivity was tested ex vivo after femoral arterial infusion of prostacyclin, acetylcholine, a cyclooxygenase inhibitor, and after acute one-leg knee extensor exercise. Results Basal platelet reactivity (%aggregation) to TRAP-6 (1 μm) was higher in the postmenopausal, 59% (50-68), than the premenopausal women, 45% (35-55). Exercise training reduced basal platelet reactivity to collagen (1 μg mL -1 ) in the premenopausal women only: from 63% (55-71%) to 51% (41-62%). After the training intervention, platelet aggregation was more inhibited by the arterial prostacyclin infusion and the acute exercise in both premenopausal and postmenopausal women. Conclusions These

The most effective dietary pattern for breast cancer prevention has been greatly debated in recent years. Studies have examined hypocaloric diets, with particular emphasis on macronutrient composition, yielding inconclusive data. The objective of this study was to examine the effects of calorie-restricted low-fat and low-carbohydrate diets (LFD and LCD, respectively) on circulating adipokines among overweight and obese premenopausal women. Seventy-nine overweight and obese premenopausal women were randomized to either LFD or LCD, with increased physical activity, for 52 weeks. Serum adiponectin, leptin and the adiponectin-to-leptin ratio (A/L) were measured at baseline, and at weeks 34 and 52 to assess intervention effects. While there were no significant changes in serum adiponectin concentrations following the LCD and LFD interventions, leptin concentrations significantly decreased by week 34 of the intervention period (LCD: 35.3%, P = 0.004; LFD: 30.0%, P = 0.01), with no difference by intervention arm. At week 52, these reductions were statistically non-significant, indicating a return to baseline levels by the end of the intervention. While there were non-significant increases in the A/L ratio following the LCD and LFD intervention arms, the overall trend, across groups, was marginally significant (P = 0.05) with increases of 16.2% and 35.1% at weeks 34 and 52, respectively. These findings suggest that caloric-restricted LCD and LFD dietary patterns favorably modify leptin and possibly the A/L ratio, and lend support to the hypothesis that these interventions may be effective for obesity-related breast cancer prevention through their effects on biomarkers involved in metabolic pathways.

The influence of body weight and weight change on age at natural menopause (ANM) is controversial. We aimed to explore these associations by overcoming two possible reasons for inconsistent findings: (1) a lack of information on weight change from a fixed time point up until menopause and (2) a possibility of capturing a spurious association between later ANM and greater weight gain because of a longer time span. Cross-sectionally, we evaluated static (body mass index [BMI] at age 25 y and height) and dynamic (history of premenopausal episodic weight loss and BMI gain rate) anthropometric indicators as predictors of ANM in Cox proportional hazards models. BMI gain rate was calculated based on weight change from age 25 y to menopause (or to current age in premenopausal women). Of 1,106 women, 46% were postmenopausal. Dynamic anthropometric indicators were stronger determinants of ANM compared with static indicators. Being in the higher quartile of BMI gain rate and having a history of episodic weight loss of more than 5 kg were independently associated with later ANM (hazard ratio [95% CI], 0.832 [0.765-0.905] and 0.433 [0.344-0.546], respectively). After controlling for history of episodic weight loss of more than 5 kg, smoking and premenopausal type 2 diabetes emerged as time-dependent predictors of ANM (hazard ratio [95% CI], 1.371 [1.093-1.720] and 1.640 [1.141-2.356], respectively). Premenopausal BMI gain rate and premenopausal history of episodic weight loss of more than 5 kg are independently associated with later ANM. Smoking predicts an earlier menopause after the age of initiation and type 2 diabetes predicts an earlier menopause after the age of diagnosis. The latter two associations are significant only after adjusting for a history of episodic weight loss of more than 5 kg.

Postural bowleg is a subclinical entity with both aesthetic and functional outcomes and appears to be common in East Asian countries. Internal rotation of the hip joint is associated with varus alignment at the knee joint of the bowleg. Strengthening exercise for the hip external rotator muscles seems to be effective in improving varus alignment of bowleg, but no standardized exercise program exists. A standardized active resistance strengthening exercise for hip external rotator muscles could improve varus alignment of the lower limb in bowlegged Korean women. In this article, a case series study was conducted to observe changes following a standardized 3-month program using equipment designed for strengthening of the hip external rotator muscles. Photogrammetric and radiographic data were used to compare the gap between knees and tibiofemoral (TF) angles before and after the exercise program. As a result, on average, the knee gap decreased by 1.6 cm. The TF angle decreased by 1.5°. Regression analysis revealed a statistically significant association between changes in knee gap and TF angle. The standardized 3-month active resistance strengthening exercise program of hip external rotator muscles was effective in improving postural deviation and cosmetic outcomes in bowlegged Korean women.

Tamoxifen is the standard-of-care treatment for estrogen receptor-positive premenopausal breast cancer. We examined tamoxifen metabolism via blood metabolite concentrations and germline variations of CYP3A5, CYP2C9, CYP2C19 and CYP2D6 in 587 premenopausal patients (Asians, Middle Eastern Arabs, Caucasian-UK; median age 39 years) and clinical outcome in 306 patients. N-desmethyltamoxifen (DM-Tam)/(Z)-endoxifen and CYP2D6 phenotype significantly correlated across ethnicities (R2: 53%, P<10−77). CYP2C19 and CYP2C9 correlated with norendoxifen and (Z)-4-hydroxytamoxifen concentrations, respectively (P<0.001). DM-Tam was influenced by body mass index (P<0.001). Improved distant relapse-free survival (DRFS) was associated with decreasing DM-Tam/(Z)-endoxifen (P=0.036) and increasing CYP2D6 activity score (hazard ratio (HR)=0.62; 95% confidence interval (CI), 0.43–0.91; P=0.013). Low (<14 nM) compared with high (>35 nM) endoxifen concentrations were associated with shorter DRFS (univariate P=0.03; multivariate HR=1.94; 95% CI, 1.04–4.14; P=0.064). Our data indicate that endoxifen formation in premenopausal women depends on CYP2D6 irrespective of ethnicity. Low endoxifen concentration/formation and decreased CYP2D6 activity predict shorter DRFS. PMID:25091503

Although it has been well-documented that obesity is associated with decreased risk of premenopausal breast cancer and increased risk of postmenopausal breast cancer, it is unclear whether these associations differ among breast cancer subtypes defined by the tumor protein expression status of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). We evaluated the associations of body mass index (BMI) at age 18 years and recent BMI in relation to risk of breast cancer overall and ER/PR/HER2-defined subtypes, in 6320 women (3934 case-patient participants, 2386 control participants) aged 35-64 years, who participated in one of three population-based case-control studies. We estimated multivariable-adjusted odd ratios (ORs) and corresponding 95% confidence intervals (CIs) using polychotomous unconditional logistic regression methods for case-control comparisons in premenopausal women and postmenopausal women. BMI at age 18 years was inversely associated with risk of breast cancer, particularly among premenopausal women (≥ 25 vs. < 20 kg/m 2 , OR = 0.72, 95% CI = 0.53-0.96; per 5 kg/m 2 increase, OR = 0.83, 95% CI = 0.73-0.95). This inverse association did not differ across ER/PR/HER2-defined subtypes or by race (white women, African-American women). Recent BMI was not associated with risk of premenopausal breast cancer after adjustment for BMI at age 18 years; nevertheless, the analysis for the joint effects of BMI at age 18 years and recent BMI showed that premenopausal women in the highest categories of the two BMI measures (≥ 25 kg/m 2 at age 18 years and ≥ 30 kg/m 2 for recent BMI) had 46% lower risk of breast cancer than premenopausal women in the lowest categories of the two BMI measures (< 20 kg/m 2 at age 18 years and < 25 kg/m 2 for recent BMI; OR = 0.54, 95% CI = 0.38-0.78). Neither measure of BMI was statistically significantly associated with risk of

As one of the fastest growing ethnic minority groups in the United States, Korean American (KA) women experience a heightened cervical cancer burden. The advent of the human papillomavirus (HPV) vaccine offers an unprecedented opportunity to eliminate cervical cancer disparities in KA women. However, the uptake of HPV vaccine among KA adolescents remains suboptimal. Hence, we set out to explore knowledge, perceptions, and decision making about HPV vaccination among KA women. We conducted four focus groups of 26 KA women who participated in a community-based, randomized, controlled trial to promote breast and cervical cancer screening. Focus group data were analyzed using qualitative content analysis. Four main themes emerged from the focus groups: 1) limited awareness and knowledge of HPV vaccine, 2) perceptions and beliefs about HPV vaccination (acceptance, negative perceptions, ambivalence), 3) patterns of decision making about HPV vaccination (hierarchical, peer influenced, autonomous, and collaborative), and 4) promoting HPV education and information sharing in the Korean community. KA women are generally positive toward HPV vaccination, but lack awareness and knowledge about HPV. Culturally tailored HPV education programs based on KA women's decision-making patterns and effective information sharing by trustworthy sources in comfortable environments are suggested strategies to promote HPV vaccination in the KA community. The findings point to the need for a multilevel approach to addressing linguistic, cultural, and system barriers that the recent immigrant community faces in promoting HPV vaccinations. In the development of targeted interventions for KA women, educational strategies and patterns of decision making need to be considered. Copyright © 2015 Jacobs Institute of Women's Health.

Cancer is the leading cause of death for Korean-Americans (KAs), while cancer screening rates among KAs have been consistently low. Seven semi-structured focus group interviews with 34 KA women aged 40 or older in the Washington, DC metropolitan area were conducted to explore the perceptions of KA women about seeking physical examinations and cancer screening services in Korea. Data were analyzed using a framework approach. Informants positively perceived the use of health screening services in Korea in comparison to seeking such services in the US. Decision-making factors included cost benefits, high quality services, and more convenient screening procedures in Korea. These benefits outweighed the risks of delaying health care and travelling a vast distance with incurring additional travel costs. Motivations to seek these services in Korea included opportunities to visit their homeland and to enjoy comfortable communication with their native language. The increase of available information about Korean medical services due to the industry's aggressive marketing/PR was identified as a facilitator. Most informants did not recognize possible negative health outcomes of obtaining services in Korea such as inappropriate follow up care if having abnormal findings. Educational programs are needed to educate KAs about the benefits and risks of getting the services in Korea and proper follow up care in the US. Health care providers need to know the different cancer risks and screening needs for this population.

The impact of chronic exposure to smoke from biomass burning on respiratory health has been examined. Six-hundred and eighty-one non-smoking women (median age 35 years) from eastern India who cook exclusively with biomass (wood, dung and crop residues) and 438 age-matched women from similar neighborhood who cook with liquefied petroleum gas (LPG) were examined. Pulmonary function test was done by spirometry. The concentrations of particulate matter having diameter of < 10 µm (PM10) and < 2.5 µm (PM2.5) in indoor air was measured by real-time aerosol monitor. Compared with LPG users, biomass users had greater prevalence of upper (50.9 versus 28.5%) and lower respiratory symptoms (71.8 versus 30.8%) and dyspnea (58.4 versus 19.9%). They showed reduction in all parameters measured by spirometer especially in mid-expiratory volume. PM10 and PM2.5 concentration in biomass using kitchen were 2-3-times more than LPG-using kitchen, and the decline in spirometry values was positively associated PM10 and PM2.5 levels in indoor air after controlling education, family income and kitchen location as potential confounders. Overall, 29.7% of biomass users and 16.4% of LPG users had deficient lung function, and restrictive type of deficiency was predominant. Chronic obstructive pulmonary disease (COPD) was diagnosed in 4.6% of biomass and 0.9% of LPG users. Women who predominantly used dung cake and did not possess separate kitchen had poorer lung function. Cumulative exposure to biomass smoke causes lung function decrement and facilitates COPD development even in non-smoking and relatively young pre-menopausal women.

Controversy exists regarding whether increasing dairy intake without energy restriction would lead to weight loss. We aimed to compare the potential weight-reducing effects of kefir drink (a probiotic dairy product) and milk in a dairy-rich non-energy-restricted diet in overweight or obese premenopausal women. One hundred and forty-four subjects were assessed for eligibility in this single-center, multi-arm, parallel-group, randomized controlled trial. Of these, seventy-five eligible women aged 25-45 years were randomly assigned to three groups, labeled as control, milk, and kefir, to receive an outpatient dietary regimen for 8 weeks. Subjects in the control group received a diet providing a maintenance level of energy intake, containing 2 servings/day of low-fat dairy products, while those in the milk and kefir groups received a weight maintenance diet, containing 2 additional servings/day (a total of 4 servings/day) of dairy products from low-fat milk or commercial kefir drink, respectively. Anthropometric outcomes including weight, body mass index (BMI), and waist circumference (WC) were measured every 2 weeks. Fifty-eight subjects completed the study. Using analysis of covariance models in the intention-to-treat population (n = 75), we found that at 8 weeks, subjects in the kefir and milk groups had significantly greater reductions in weight, BMI, and WC compared to those in the control group (all p < 0.01). However, no such significant differences were found between the kefir and milk groups. Kefir drink leads to a similar weight loss, compared with milk, in a dairy-rich non-energy-restricted diet in overweight or obese premenopausal women. However, further studies are warranted.

The aim of this study was to assess side effects of aromatase inhibitor anastrozole in the prevention of N-methyl-N-nitrosourea - induced pre-menopausal mammary carcinogenesis in female Sprague-Dawley rats. This model mimicked situation in healthy, but from the point of view of the development of breast cancer, high-risk pre-menopausal women.

Aromatase inhibitor anastrozole was used as a chemopreventive agent taken by the animals in the food during the whole period of time of the experiment. Group 1 - the control group had taken food without anastrozole, the groups 2 and 3 with anastrozole in various concentrations - 0.05 mg/1 kg of food (ANA 0.05) and 0.5 mg/1 kg of food (ANA 0.5).

In anastrozole-treated animals in comparison with untreated animals, macroscopic changes of uterus and vagina were not found. The values of absolute and relative wet weight of uterus and vagina in the groups ANA 0.05 and ANA 0.5 were comparable with the control. Histological examination did not show atrophic changes in endometrium of uterus and in epithelium of vagina in anastrozole-treated animals. In the group ANA 0.5 myometrium was significantly grosser than in the group ANA 0.05 (P<0.05). Anastrozole neither affects parameters of plasma lipid metabolism (triacylglycerols, total cholesterol, low - density lipoprotein cholesterol and high - density lipoprotein cholesterol) nor serum levels of sex hormones (estradiol, testosterone, dehydroepiandrosterone). Compact bone thickness in the groups with anastrozole was significantly increased in comparison with untreated animals (P<0.001). A significant increase in body weight was found in the group ANA 0.5 compared with the control group (P<0.01). The significant increase in body weight gain was not attended by the significant increase in food intake.

Background: Breast cancer (BC) is the leading malignancy in women with high incidence and mortality worldwide. Obesity is one of several established risk factors for chronic diseases including cancer. The objective of this research was to determine the association of body mass index (BMI) with BC among Thai premenopausal women (TPW). Materials and Methods: A case-control study was conducted among TPW attending the National Cancer Institute in Bangkok, with 257 cases and 257 controls in 2013-2014. Cases and controls were matched by age (± 5 years), residential area and duration of attending. Data were collected with a questionnaire comprising 2 parts: part 1 socio-demographic characteristics, and part 2 health risk behavior and reproductive factors and BMI. The obtained data were analyzed using descriptive and analytic statistics with a computerized statistical package. Results: The study participants were mainly 40-44 years old (60 %) with an average age of 39 years. The major type of BC was the invasive ductal carcinoma (91.8%). On univariate analysis, risk factors for BC among the TPW were family history of BC, history of benign breast tumors, younger age at menarche, parity, miscarriage, contraceptive use, passive smoking, multivitamin use, and BMI (p<0.05). Multivariable conditional logistic regression analysis, controlling for possible confounding factors, revealed that a BMI 25-29.9 and ≥ 30 kg/m2 increased the risk of BC by a factor of 2.09 and 2.37 times, respectively (OR=2.09, 95%CI =1.09-3.97; OR=2.37, 95%CI =1.24-10.06). Conclusions: A surveillance system of obesity should be conducted in cooperation with information regarding physical activities and weight control among TPW as an essential measure to reduce BC risk.

Background We undertook this study to investigate the association of a genetic polymorphism of the insulin-like growth factor, IGF-I189, on body composition, exercise performance and exercise economy, after controlling for the independent effect of race as assessed by African genetic admixture (AFADM). Methods A total of 114 premenopausal sedentary women were genotyped for IGF-I189, obtaining measures of fat mass, lean body mass, VO2 during cycling and stairclimbing, time on treadmill and leg strength. A quantitative value for AFADM was derived from genotypic information of approximately 40 ancestry informative markers and used as covariate in statistical models. Results After adjusting for AFADM, IGF-I189 was negatively associated with lean body mass (p = 0.029) and lean leg mass (p = 0.050). Leg strength was not associated with the presence/absence of IGF-I189 (p = 0.380), but carriers of the allele demonstrated a longer time on the treadmill (p = 0.015) after adjusting for AFADM. There was also a negative relationship between oxygen uptake during cycling and presence of the IGF-I189 independent of AFADM (p = 0.010). Conclusion Independent of AFADM, individuals with IGF-I189 are more likely to have low leg lean mass and to perform better in activities requiring exercise economy and endurance performance.

The aim of the study was to observe the changes in blood oxidative stress levels by oral contraceptive (OC) and/or dydrogesterone (DG) treatment. A retrospective cohort of 27 premenopausal women with primary dysmenorrhea consisted of the OC treatment group (N = 17) and the DG treatment group (N = 10) by choice of the initial treatment. The OC group included two subgroups: patients with continuous OC treatment (treated for at least 15 months, N = 10) and patients with discontinuous OC treatment (switched to DG treatment after approximately 6 months of initial OC treatment: N = 7). The DG group had 15 months of continuous DG treatment. Blood parameters, including diacron-reactive oxygen metabolites (d-ROMs: an oxidative stress marker), were measured. The d-ROMs level was elevated in the OC group 3 months after initial treatment (mean: from 321 (at baseline) to 512 Carratelli Units (Carr U); P < 0.01), while such changes were not observed in the DG group. The d-ROMs level was reduced in the discontinuous OC subgroup 15 months after initial treatment (from 508 (3 months after initial treatment) to 372 Carr U; P < 0.01), while such changes were not observed in the continuous OC subgroup. The DG group displayed unchanged the d-ROMs level. Replacing OC with DG can attenuate oxidative stress as elevated by OC, thereby alleviating the possible vascular risks with OC treatment.

Osteoporosis is prevalent among postmenopausal women, and increasing evidence has linked salt intake with this disease. In this article, we explored the association between dietary sodium intake and osteoporosis in Korean postmenopausal women. We analyzed data for 3635 postmenopausal women extracted from the 2008-2011 Korea National Health and Nutrition Examination Survey. We found that 1542 participants (42.4%) have osteoporosis. The adjusted prevalence rates of osteoporosis at the lumbar spine were significantly higher in participants who consumed ≥4001 mg of salt than those who consumed ≤2000 mg. At the femoral neck, rates were significantly higher for those who consumed ≥5001 mg compared with those who consumed ≤4000 mg. Participants with a higher sodium intake showed a significantly higher odds ratio of developing lumbar and femoral neck osteoporosis, compared with those with a lower intake. Our results suggest that excessive daily sodium intake is associated with a higher osteoporosis prevalence in Korean postmenopausal women.

The prevalence of metabolic syndrome (MetS) has been increasing among Koreans, and middle-aged and older women are at risk of metabolic syndrome. Effective strategies to promote lifestyle modification need to be developed. We examined the effects of a self-management program on improving the cardiovascular health status and promoting healthy behaviors among overweight or obese Korean women at risk of metabolic syndrome. A pretest and posttest intervention design was used. Sixty women participated in a group teaching session. They also received a pedometer and a diary for self-monitoring. On the basis of blood test results, women's metabolic syndrome status was identified. Thirty women with metabolic syndrome received additional tailored counseling and weekly follow-up calls for 4 weeks, whereas 30 women without metabolic syndrome did not receive any tailored counseling or follow-up calls. Twenty-three women in the MetS group and 22 women in the non-MetS group completed the posttest. Overall, women significantly improved their cardiovascular health status including systolic blood pressure, diastolic blood pressure, body mass index, low-density lipoprotein, triglycerides, number of metabolic syndrome risk factors, and 10-year risk estimates from pretest to posttest. Seventy-eight percent of the MetS group (n = 18) no longer had metabolic syndrome, whereas 5% of the non-MetS group (n = 1) became to have metabolic syndrome. Women significantly increased frequency and duration of walking per week and significantly decreased the time spent sitting. Promoting self-management for healthy behaviors might be effective for obese or overweight women to prevent metabolic syndrome and cardiovascular diseases, if it is tailored to their health needs.

Young women (20-39 years-old) with breast cancer are diagnosed with more aggressive tumours and consequently have poorer survival. However, there is an evidence gap as to whether age has an independent effect on survival of pre-menopausal women diagnosed with HR+/Her2- tumours. The aim of this population-based study was to compare characteristics at diagnosis, determinants of treatment and survival in women aged 20-39 and 40-49 years diagnosed with HR+/Her2- tumours. From the National Cancer Registry Ireland, we identified women aged 20-49 diagnosed with a first invasive HR+/Her2- breast cancer during 2002-2008. Women aged 20-39 were compared to those aged 40-49 years. Poisson regression with robust error variance was used to explore the impact of age on treatment receipt. Associations between age and survival from all causes was investigated using Cox models. In multivariate models, women aged 20-39 significantly more often having no cancer-directed surgery (IRR=1.49, 95%CI 1.07, 2.08). In those having surgery, younger age was associated with significantly higher likelihood of receiving chemotherapy; age was not associated with receipt of adjuvant radiotherapy or endocrine therapy. Women aged 20-39 undergoing surgery were significantly more likely to die than women aged 40-49 (HR=1.84, 95%CI: 1.31, 2.59). Age is an independent prognostic factor in younger women diagnosed with HR+/Her2- breast cancer, supporting the hypothesis that breast cancer in women under 40 has more aggressive behaviour, even within HR+/Her2- tumours. Future research should explore the reasons for poorer survival in order to inform strategies to improve outcomes in this age group. Copyright © 2016 Elsevier Ltd. All rights reserved.

Objective. The purpose of this study was to (i) determine the cervical microbial composition in different abortion samples and to (ii) investigate the correlation between spontaneous abortion and cervical microbes in Korean women. Methods. We collected cervical swabs from women who had never undergone abortion ( N = 36), had spontaneous abortion ( N = 23), and had undergone induced abortion ( N = 88) and subjected those samples to 16S rRNA pyrosequencing. Further, factor analysis and correlation between cervical microbiota and spontaneous abortion were evaluated by logistic regression analysis. Results. In spontaneous abortion women, 16 S rRNA gene sequences showed significant increases in Atopobium vaginae , Megasphaera spp., Gardnerella vaginalis , Leptotrichia amnionii , and Sneathia sanguinegens compared to women in nonabortion group. In multivariate logistic regression analysis, A. vaginae (OD = 11.27; 95% = 1.57-81) , L. amnionii (OD = 11.47; 95% = 1.22-107.94), S. sanguinegens (OD = 6.89; 95% = 1.07-44.33), and factor 1 microbes (OD = 16.4; 95% = 1.88-42.5) were strongly associated with spontaneous abortion. Conclusions. This study showed a high prevalence of L. amnionii, A. vaginae, S. sanguinegens , and factor 1 microbes in spontaneous abortion and association with spontaneous abortion in Korean women.

Hypertension (HTN) is a major determinant of various cardiovascular events. Plasma levels of plasminogen activator inhibitor 1 (PAI-1) modulate this risk. A deletion/insertion polymorphism within the PAI-1 loci (4G/4G, 4G/5G, 5G/5G) affects the expression of this gene. The present study investigated the association between PAI-1 loci polymorphisms and HTN in Korean women. Korean women (n = 1312) were enrolled in this study to evaluate the association between PAI-1 4G/5G gene polymorphisms and HTN as well as other metabolic risk factors. PAI-1 loci polymorphisms were investigated using polymerase chain reaction amplification and single-strand conformation polymorphism analysis. The three genotype groups differed with respect to systolic blood pressure (P = 0.043), and diastolic blood pressure (P = 0.009) but not with respect to age, body mass index, total cholesterol, low or high density lipoprotein cholesterol, triglycerides, or fasting blood glucose. Carriers of the PAI-1 4G allele had more hypertension significantly (PAI-1 4G/5G vs. PAI-1 5G/5G, P = 0.032; PAI-1 4G/4G vs. PAI-1 5G/5G, P = 0.034). When stratified according to PAI-1 4G/5G polymorphism, there was no significant difference in all metabolic parameters among PAI-1 genotype groups in patients with HTN as well as subjects with normal blood pressure. The estimated odds ratio of the 4G/4G genotype and 4G/5G for HTN was 1.7 (P = 0.005), and 1.6 (P = 0.015), respectively. These findings might indicate that PAI-1 loci polymorphisms independently contribute to HTN and that gene-environmental interaction may be not associated in Korean women.

The purpose of this study was to investigate the health behaviors and risk factors for self-reported depression in Korean working women. This study adopted a secondary analysis from the fifth Korean National Health and Nutrition Examination Survey (KNHANES-V) for the Health Examination Survey and Health Behavior Survey, using stratified, multi-stage, cluster-sampling design to obtain a nationally representative sample. Data were gathered on extensive information including sociodemographic, occupational characteristics, health behaviors and depression. Multiple logistic regression analysis was employed to compute the odds ratio (OR) between health behaviors and depression to identify the health behaviors and the risk factors for depression with adjustment for the complex sample design of the survey. The prevalence rate of depression was 15.5% among working women. Depression was more common in older female workers and in those with part-time job. Current smokers were significantly more likely to be depression-positive. In a multiple logistic regression analysis, significant variables of depression were marital status (OR = 2.02; 95% CI [1.05, 3.89]), smoking status (OR = 1.55; 95% CI [1.01, 2.38]), stress (OR = 0.20; 95% CI [0.15, 0.26]), employment condition (OR = 1.77; 95% CI [1.34, 2.33]) and health status (OR = 2.10; 95% CI [1.53, 2.87]). Based on the study, factors leading to depression were marital status, current smoking, stress, employment condition and self-reported health status. Further studies are expected to unravel the characteristics of stress. Health care providers for women need to evaluate underreported depression and change their associated health behaviors. Also it is necessary to establish preventive strategies for female workers to control the negative effect of depression in the workplace. Copyright © 2015. Published by Elsevier B.V.

Biomass burning is a major source of indoor air pollution in rural India. The authors investigated in this study whether cumulative exposures to biomass smoke cause activation of the serine/threonine kinase Akt in airway cells and peripheral blood lymphocytes (PBL). For this, the authors enrolled 87 premenopausal (median age 34 years), nonsmoking women who used to cook with biomass (wood, dung, crop wastes) and 85 age-matched control women who cooked with cleaner fuel liquefied petroleum gas. Immunocytochemical and immunoblotting assays revealed significantly higher levels of phosphorylated forms of Akt protein (p-Akt(ser473) and p-Akt(thr308)) in PBL, airway epithelial cells, alveolar macrophages, and neutrophils in sputum of biomass-using women than control. Akt activation in biomass users was associated with marked rise in generation of reactive oxygen species and concomitant depletion of superoxide dismutase. Measurement of particulate matter having a diameter of less than 10 and 2.5 µm in indoor air by real-time aerosol monitor showed 2 to 4 times more particulate pollution in biomass-using households, and Akt activation was positively associated with particulate pollution after controlling potential confounders. The findings suggest that chronic exposure to biomass smoke activates Akt, possibly via generation of oxidative stress.

Bone loss before and around the time of menopause is not well characterized by longitudinal studies. We measured bone mineral density at various skeletal sites--total body, femoral neck, trochanter, anteroposterior (AP) and lateral spine, and forearm--with dual-energy X-ray absorptiometry in a large prospective cohort of 272 untreated pre- and perimenopausal women aged 31-59 years, at 1 year intervals for 3 years. Sex steroids and the following markers of bone remodeling were measured: serum osteocalcin (OC), procollagen I carboxyterminal extension peptide, bone alkaline phosphatase (BAP) and urinary crosslinks (CTX and NTX). Seventy-six women were classified as perimenopausal and 196 as premenopausal. Over the 3 years, premenopausal women had no significant bone loss at any site and a small but significant increase in bone mineral density at the trochanter, total hip, AP spine and radius. Perimenopausal women significantly lost bone from cancellous and cortical sites, i.e., the femoral neck, trochanter and lumbar spine. In perimenopausal women with increased follicle stimulating hormone, the rate of bone loss at the femoral neck correlated negatively with OC and BAP. In perimenopausal women, serum estradiol levels decreased during the 3 years of follow-up and bone loss from the trochanter and the AP spine was correlated with serum estradiol after 3 years. In conclusion, among premenopausal women there is no bone loss. In contrast, there is a rapid and diffuse bone loss in perimenopausal women, related to decreased estrogen secretion. Bone markers may be useful to identify these women losing bone.

Bioelectrical impedance analysis (BIA), a device that analyzes the current conduction differences between the fat and water components is widely used for reasons that include convenience of use, non-invasiveness, safety, and low cost. Dual energy X-ray absorptiometry (DXA) allows for the assessment of total body and regional lean and fat tissues and bone mineral content (BMC). The objective of this study was to compare body composition assessments by BIA and DXA before and after a 6-week herbal diet intervention program in 50 pre-menopausal women [mean +/- SD: age 30.58 +/- 6.15, body mass index (BMI) 31.72 +/- 3.78]. Waist-to-hip ratio (WHR) was measured by BIA and anthropometry. Lean body mass (LBM), body fat (BF), BMC and percent body fat (%BF) were measured by BIA and DXA. Highly significant correlations were observed between BIA and DXA measurements for LBM, BF, BMC and %BF (r = 0.73, 0.93, 0.53, 0.79, respectively) before the intervention. Differences between BIA and DXA measurements were observed in LBM, BF, %BF and BMC before intervention (p < 0.01) where WHR by BIA was significantly higher compared to anthropometry before (p < 0.01) and after the intervention (p < 0.01). BIA underestimated LBM by 1.85 kg and overestimated BF by 2.54 kg compared to DXA before the intervention. Although BIA and DXA showed highly significant correlations for LBM, BF, BMC and %BF before the intervention, they did not produce statistically comparable results in pre-menopausal Korean women and therefore should not be used interchangeably when measuring body composition.

This research examined the prevalence and correlates of intimate partner violence (IPV) among younger, middle-aged, and older Korean American women. Data were drawn from telephone interviews of a population-based, representative probability sample (N = 592) of female adults of Korean descent residing in California, with a completion rate of 70%. Data were grouped by age. In each group, psychological aggression was the most common type of IPV in the past year, followed by a moderate form of sexual coercion, while physical assault and injury were infrequent. Immigration stress was associated with psychological aggression in all three groups, and partner alcohol use was associated in none. Other predictors varied by group. Results suggest that psychological abuse is a serious issue, and that women’s life stage is an important consideration in IPV among Korean Americans. Findings, which sometimes diverged from those of prior studies of this population, merit further investigation. PMID:23645971

Abstract Dietary patterns are a risk factor for metabolic syndrome (MetS). The prevalence of MetS has increased in Korea, and this condition has become a public health issue. Therefore, the present cross-sectional study aimed to identify the associations between dietary patterns and the risk of MetS among Korean women. The data of 5189 participants were analyzed to determine dietary intake and lifestyle. A principal components analysis was employed to determine participant dietary patterns with regard to 106 food items. MetS was diagnosed using the National Cholesterol Education Program, Adult Treatment Panel III. Logistic regression analyses were applied to evaluate the associations between dietary pattern quintiles and MetS and to generate odds ratios (ORs) and 95% confidence intervals (CIs) after adjusting for potential confounders. Three dietary patterns were identified: “traditional,” “western,” and “prudent.” The “prudent” dietary pattern consisted of a high intake of fruits and fruit products as well as nuts, dairy, and a low consumption of grains; this pattern was negatively associated with the risk of MetS. The highest quintile of the “prudent” dietary pattern was significantly less likely to develop MetS (OR: 0.5, 95% CI: 0.36–0.68, P for trend <0.001) compared with the lowest quintile. This pattern was also negatively associated with all of the MetS diagnostic criteria: abdominal obesity (OR: 0.52, 95% CI: 0.41–0.65), blood pressure (OR: 0.72, 95% CI: 0.59–0.87), triglycerides (OR: 0.67, 95% CI: 0.52–0.85), fasting glucose (OR: 0.64, 95% CI: 0.43–0.95), and high-density lipoprotein cholesterol (OR: 0.53, 95% CI: 0.42–0.68). However, the “traditional” and “western” dietary patterns were not associated with the risk of MetS. The “prudent” dietary pattern was negatively associated with the risk of developing MetS among Korean women. PMID:26313795

Kefir drink causes a significant yet similar improvement in serum lipid profile, compared with low-fat milk, in a dairy-rich diet in overweight or obese premenopausal women: A randomized controlled trial.

Controversy exists as to whether the lipid-lowering properties of kefir drink (a fermented probiotic dairy product) in animal models could be replicated in humans. To assess and compare the potential lipid-lowering effects of kefir drink with low-fat milk in a dairy-rich diet in overweight or obese premenopausal women. In this 8-week, single-center, multiarm, parallel-group, outpatient, randomized controlled trial, 75 eligible Iranian women aged 25 to 45 years were randomly allocated to kefir, milk, or control groups. Women in the control group received a weight-maintenance diet containing 2 servings/d of low-fat dairy products, whereas subjects in the milk and kefir groups received a similar diet containing 2 additional servings/d (a total of 4 servings/d) of dairy products from low-fat milk or kefir drink, respectively. At baseline and study end point, serum levels/ratios of total cholesterol (TC), low- and high-density lipoprotein cholesterol (LDLC and HDLC), triglyceride, Non-HDLC, TC/HDLC, LDLC/HDLC, and triglyceride/LDLC were measured as outcome measures. After 8 weeks, subjects in the kefir group had significantly lower serum levels/ratios of lipoproteins than those in the control group (mean between-group differences were -10.4 mg/dL, -9.7 mg/dL, -11.5 mg/dL, -0.4, and -0.3 for TC, LDLC, non-HDLC, TC/HDLC, and LDLC/HDLC, respectively; all P < .05). Similar results were observed in the milk group. However, no such significant differences were found between the kefir and milk groups. Kefir drink causes a significant yet similar improvement in serum lipid profile, compared with low-fat milk, in a dairy-rich diet in overweight or obese premenopausal women.

Analysis of the prevalence of and factors associated with overactive bladder in adult Korean women

PubMed Central

2017-01-01

Background Overactive bladder (OAB) is one of the most prevalent lower urinary tract conditions and has been suggested to be related to various factors. We assessed the prevalence of and factors associated with OAB in women based on a large cross-sectional, population-based study of adult Korean women. Methods The Korean community health survey (KCHS) of 2012 was reviewed, and 107,950 female participants aged 19 to 107 years were identified for inclusion in this study. The overactive bladder symptom score (OABSS) was used to define and classify OAB as mild, moderate, or severe. Numerous variables, including marital status; physical activity; education and income levels; type of occupation; body mass index (BMI); smoking; alcohol; sleep time; and medical history of hypertension, diabetes mellitus, hyperlipidemia, or cerebral stroke, were evaluated. The correlation of these variables with the prevalence of OAB was analyzed using simple and multiple logistic regression analyses with complex sampling. Results The results showed that 5.2% of adult women experienced OAB. Multiple regression analyses showed a significant correlation between the following variables and OAB: older age (adjusted odds ratio [AOR] = 1.44, 95% confidence interval [CI] = 1.39–1.50, P < 0.001 as 10 years older); married status (AOR = 0.83, 95%CI = 0.70–0.96, P = 0.016); lower level of income (AOR = 1.50, 95%CI = 1.34–1.68, P < 0.001); high BMI (AOR = 1.33, 95%CI = 1.23–1.44, P < 0.001); smoking (AOR = 1.24, 95%CI = 1.04–1.47, P < 0.001); long sleep time (AOR = 1.95, 95%CI = 1.69–2.26); and medical history of hypertension (AOR = 1.11, 95%CI = 1.03–1.21, P = 0.011), diabetes mellitus (AOR = 1.38, 95%CI = 1.25–1.53, P < 0.001), hyperlipidemia (AOR = 1.27, 95%CI = 1.16–1.39, P < 0.001), and cerebral stroke (AOR = 2.04, 95%CI = 1.73–2.41, P < 0.001). The level of stress showed a dose-dependent association with OAB (AOR [95%CI] = 3.28 [2.81–3.83] > 2.11 [1.91–2.33] >1.28 [1.16�

Dietary choline requirements of women: effects of estrogen and genetic variation.

Choline is obtained from the diet and from the biosynthesis of phosphatidylcholine. Phosphatidylcholine is catalyzed by the enzyme phosphatidylethanolamine-N-methyltransferase (PEMT), which is induced by estrogen. Because they have lower estrogen concentrations, postmenopausal women are more susceptible to the risk of organ dysfunction in response to a low-choline diet. A common genetic polymorphism (rs12325817) in the PEMT gene can also increase this risk. The objective was to determine whether the risk of low choline-related organ dysfunction increases with the number of alleles of rs12325817 in premenopausal women and whether postmenopausal women (with or without rs12325817) treated with estrogen are more resistant to developing such symptoms. Premenopausal women (n = 27) consumed a choline-sufficient diet followed by a very-low-choline diet until they developed organ dysfunction (or for 42 d), which was followed by a high-choline diet. Postmenopausal women (n = 22) were placed on the same diets but were first randomly assigned to receive estrogen or a placebo. The women were monitored for organ dysfunction and plasma choline metabolites and were genotyped for rs12325817. A dose-response effect of rs12325817 on the risk of choline-related organ dysfunction was observed in premenopausal women: 80%, 43%, and 13% of women with 2, 1, or 0 alleles, respectively, developed organ dysfunction. Among postmenopausal women, 73% who received placebo but only 18% who received estrogen developed organ dysfunction during the low-choline diet. Because of their lower estrogen concentrations, postmenopausal women have a higher dietary requirement for choline than do premenopausal women. Choline requirements for both groups of women are further increased by rs12325817. This trial was registered at clinicaltrials.gov as NCT00065546.

This study investigated dietary patterns and nondietary determinants of suboptimal iron status (serum ferritin < 20 μg/L) in 375 premenopausal women. Using multiple logistic regression analysis, determinants were blood donation in the past year [OR: 6.00 (95% CI: 2.81, 12.82); P < 0.001], being Asian [OR: 4.84 (95% CI: 2.29, 10.20); P < 0.001], previous iron deficiency [OR: 2.19 (95% CI: 1.16, 4.13); P = 0.016], a "milk and yoghurt" dietary pattern [one SD higher score, OR: 1.44 (95% CI: 1.08, 1.93); P = 0.012], and longer duration of menstruation [days, OR: 1.38 (95% CI: 1.12, 1.68); P = 0.002]. A one SD change in the factor score above the mean for a "meat and vegetable" dietary pattern reduced the odds of suboptimal iron status by 79.0% [OR: 0.21 (95% CI: 0.08, 0.50); P = 0.001] in women with children. Blood donation, Asian ethnicity, and previous iron deficiency were the strongest predictors, substantially increasing the odds of suboptimal iron status. Following a "milk and yoghurt" dietary pattern and a longer duration of menstruation moderately increased the odds of suboptimal iron status, while a "meat and vegetable" dietary pattern reduced the odds of suboptimal iron status in women with children.

The impact of a low-carbohydrate/high-protein diet compared with a high-carbohydrate/low-fat diet on ratings of hunger and cognitive eating restraint were examined. Overweight premenopausal women consumed a low-carbohydrate/high-protein (n=13) or high-carbohydrate/low-fat diet (n=15) for 6 weeks. Fasting body weight (BW) was measured and the Eating Inventory was completed at baseline, weeks 1 to 4, and week 6. All women experienced a reduction in BW (P<.01), although relative BW loss was greater in the low-carbohydrate/high-protein vs high-carbohydrate/low-fat group at week 6 (P<.05). Based on Eating Inventory scores, self-rated hunger decreased (P<.03) in women in the low-carbohydrate/high-protein but not in the high-carbohydrate/low-fat group from baseline to week 6. In both groups, self-rated cognitive eating restraint increased (P<.01) from baseline to week 1 and remained constant to week 6. Both diet groups reported increased cognitive eating restraint, facilitating short-term weight loss; however, the decrease in hunger perception in the low-carbohydrate/high-protein group may have contributed to a greater percentage of BW loss.

To examine associations between menopausal status and physical performance in middle-aged women from the Northeast region of Brazil. Cross-sectional study of women between 40 to 65 years old living in Parnamirim. Women were recruited by advertisements in primary care neighborhood centers across the city. Physical performance was assessed by grip strength, gait speed and chair stands. Menopausal status was determined using the Stages of Reproductive Aging Workshop classification and women were classified in: premenopausal, perimenopausal or postmenopausal. Multiple linear regression analyses were performed to model the effect of menopausal status on each physical performance measure, adjusting for covariates (age, family income, education, body mass index, parity and age at first birth). The premenopausal women were significantly stronger and performed better in chair stands than perimenopausal and postmenopausal women. Gait speed did not vary significantly by menopausal status. In multivariate analyses, menopausal status remained statistically significant only for grip strength. In fully adjusted analyses, premenopausal women had grip strength mean of 2.226 Kgf (95% CI: 0.361 - 4.091) higher than the postmenopausal group. This study provides further evidence for the associations between menopause and physical performance in middle-aged women, since grip strength is weaker in peri and postmenopausal women compared to premenopausal, even adjusted for age and other covariates.

Hormones and sexuality in postmenopausal women: a psychophysiological study.

Laan, E; van Lunsen, R H

Sexual function, including vaginal atrophy, and hormonal status, were studied in 42 naturally postmenopausal women. Vaginal pulse amplitude and subjective sexual responses during self-induced erotic fantasy and during erotic films were compared with responses of a small number of premenopausal women. As predicted, vaginal atrophy was related to estrogens but not to complaints of vaginal dryness and dyspareunia. No significant relationship was found between hormones and sexual function. Unexpectedly, most of the few correlations that did reach significance involved prolactin. The fact that prolactin was negatively associated with sexual desire, sexual arousal and vaginal lubrication during sexual activity, suggests that psychosocial factors are more important than hormone levels in postmenopausal sexual function. Comparisons with a number of premenopausal women revealed that although postmenopausal women displayed lower vaginal pulse amplitude responses prior to erotic stimulation than the premenopausal women, this difference disappeared during subsequent erotic stimulation. We argued that this finding can be interpreted as being supportive of the notion that complaints of vaginal dryness and dyspareunia should not be attributed to vaginal atrophy associated with menopause. Rather, vaginal dryness and dyspareunia seem to reflect sexual arousal problems.

Do cultural factors predict mammography behaviour among Korean immigrants in the USA?

This paper is a report of a study of the correlates of mammogram use among Korean American women. Despite the increasing incidence of and mortality from breast cancer, Asian women in the United States of America report consistently low rates of mammography screening. A number of health beliefs and sociodemographic characteristics have been associated with mammogram participation among these women. However, studies systematically investigating cultural factors in relation to mammogram experience have been scarce. We measured screening-related health beliefs, modesty and use of Eastern medicine in 100 Korean American women in 2006. Hierarchical logistic regression was used to examine the unique contribution of the study variables, after accounting for sociodemographic characteristics. Only 51% reported past mammogram use. Korean American women who had previously had mammograms were statistically significantly older and had higher perceived benefit scores than those who had not. Perceived benefits (odds ratio = 6.3, 95% confidence interval = 2.12, 18.76) and breast cancer susceptibility (odds ratio = 3.18, 95% confidence interval = 1.06, 9.59) were statistically significant correlates of mammography experience, whereas cultural factors did not correlate. Post hoc analysis showed that for women with some or good English skills, cultural factors statistically significantly correlated with health beliefs and breast cancer knowledge (P < 0.05). Nurses should consider the inclusion in culturally tailored interventions of more targeted outreach and healthcare system navigation assistance for promoting mammography screening in Korean American women. Further research is needed to unravel the interplay between acculturation, cultural factors and health beliefs related to cancer screening behaviours of Korean American women.

Introduction The objective of this study was to investigate whether caffeine intake is associated with urinary incontinence (UI) and quality of life (QOL) in Korean postmenopausal women. Materials and Methods We included 4,028 postmenopausal women who had participated in the Korea National Health and Nutrition Examination Survey IV (KNHANES IV). From the KNHANES questionnaire data, we ascertained the UI status of participants, defined as self-reported or medically diagnosed UI, and calculated their total daily caffeine intake through questions regarding the frequency of food consumption. The EuroQoL-5 Dimension (EQ-5D) descriptive system was used to evaluate QOL among the study population. Results The mean age of the study population was 63.19±0.25 years. Among the 4,028 women, the prevalence of medically diagnosed UI was 2.6% (n = 151), the prevalence of self-reported UI was 11.9% (n = 483), and the lifetime prevalence of UI was 15.8% (n = 639). In the study population, the presence of UI was not significantly different by age group, but daily caffeine consumption and the percentage of caffeine consumer decreased with age (P<0.001). Higher caffeine intake led to significantly higher prevalence of both medically diagnosed UI (p = 0.012) and self-reported UI (p = 0.040) in the study population. Even after adjusting for factors including age, parity, smoking status, hypertension and diabetes in logistic regression analysis, the positive association between caffeine intake and UI prevalence was observed in both medically diagnosed UI and self-reported UI (P = 0.017) among participants. In a subgroup analysis for EQ-5D (using continuous variables) in which we categorized participants into four groups according to UI presence and caffeine consumption, the EQ-5D scores were lower in the caffeine non-user group with UI than in the caffeine consumer group with or without UI. Conclusion In a sample of Korean postmenopausal women, the prevalence of UI increased with higher

There are no data about the main factors associated with metabolic syndrome in young premenopausal systemic lupus erythematosus (SLE) patients. The aim of the study was to evaluate the frequency of metabolic syndrome and disease- or therapy-related factors in premenopausal young SLE patients. A total of 103 premenopausal SLE patients ages <40 years were selected and compared to 35 healthy premenopausal age-matched women. Metabolic syndrome was defined according to the 2009 Joint Interim Statement. A higher frequency of metabolic syndrome (22.3% versus 5.7%; P = 0.03) was observed in the SLE group. Metabolic syndrome-SLE patients had higher SLE Disease Activity Index scores (mean ± SD 5.9 ± 7.6 versus 1.9 ± 2.7; P = 0.006), more frequently had previous renal disease (73.9% versus 51.2%; P = 0.05) and current renal disease (34.8% versus 10.0%; P = 0.008), and had higher current prednisone dose (median [range] 20 [0-60] versus 5 [0-60] mg/dl; P = 0.018) and cumulative prednisone dose (mean ± SD 41.48 ± 27.81 versus 24.7 ± 18.66 gm; P = 0.023) than those without metabolic syndrome. Chloroquine was less frequently used in metabolic syndrome-SLE patients (65.2% versus 90.0%; P = 0.008). In multivariate analysis, only current chloroquine use (prevalence ratio [PR] 0.29, 95% confidence interval [95% CI] 0.13-0.64) and cumulative prednisone were associated with metabolic syndrome (PR 1.02, 95% CI 1.01-1.04). Further estimated prevalence analysis identified the fact that antimalarial use promoted continuous decrease in the progressive metabolic syndrome prevalence associated with glucocorticoid cumulative dose. The prevalence of metabolic syndrome is high in premenopausal young adult SLE patients. Chloroquine has a protective effect on the prevalence of metabolic syndrome in these patients, and this benefit counteracts the deleterious effect of glucocorticoids in a dose-dependent manner. © 2015, American College of
