Perspectives of older women in the Netherlands: identifying motivators and barriers for healthy lifestyles and determinants of healthy aging

BackgroundWomen have a higher life expectancy than men but experience more years with physical disabilities in daily life at older ages, especially women with a migration background. This pinpoints older women as an important target group for strategies that stimulate healthy lifestyle, which benefits healthy aging. Our study investigates motivators and barriers for healthy lifestyles and perspectives on determinants of healthy aging of older women. This provides essential information for developing targeted strategies.MethodsData was collected by semi-structured digital interviews from February till June 2021. Women aged 55 years and older living in the Netherlands (n = 34) with a native Dutch (n = 24), Turkish (n = 6) or Moroccan (n = 4) migration background were included. Two main subjects were investigated: (1) motivators and barriers on their current lifestyles regarding smoking, alcohol consumption, physical activity, diet and sleep and (2) perspectives on determinants of healthy aging. Interviews were analyzed using Krueger’s framework.ResultsPersonal health was the most common motivator for a healthy lifestyle. In addition, peer pressure and being outdoors were specific motivators for physical activity. Bad weather conditions and personal dislike to be active were specific barriers. The social environment, personal preferences and personal belief to compensate with other healthy lifestyle behaviors were barriers for low alcohol consumption. Personal preferences (liking unhealthy food and not making time) were the main barriers for a healthy diet. Sleep was not perceived as a form of lifestyle behavior, but rather as a personal trait. Since there were no smokers, specific barriers were not mentioned. For Turkish-Dutch and Moroccan-Dutch women, additional barriers and motivators were culture and religion. These were strong motivators to abstain from alcohol consumption and smoking, but a barrier for a healthy diet. With regard to perspectives on determinants of healthy aging, positive views on aging and being physically active were perceived as most important. Women often wanted to increase their physical activity or healthy diet to stimulate healthy aging. Among Turkish-Dutch and Moroccan-Dutch women, healthy aging was also perceived as something in the hands of God.ConclusionsAlthough motivators and barriers for a healthy lifestyle and perspectives on healthy aging vary for distinct lifestyles, personal health is a common motivator across all lifestyles. Having a migration background added culture and religion as distinct barriers and motivations. Strategies to improve lifestyle among older women should therefore have a tailored, culture sensitive approach (if applicable) for distinct lifestyle factors.

The EVA Study: Early Vascular Aging in Women With History of Preeclampsia.

Background Early vascular aging (EVA) is associated with higher risk of adverse cardiovascular events and can be estimated noninvasively by assessing arterial hemodynamics. Women with a history of preeclampsia have increased risk of cardiovascular disease, but underlying mechanisms are incompletely understood. We hypothesized that women with a history of preeclampsia display persistent arterial abnormalities and EVA in the postpartum period. Methods and Results We performed a comprehensive, noninvasive arterial hemodynamic evaluation in women with a history of preeclampsia (n=40) and age-matched controls with previous normotensive pregnancies (n=40). We used validated methods integrating applanation tonometry with transthoracic echocardiography to obtain measures of aortic stiffness, steady and pulsatile arterial load, central blood pressure, and arterial wave reflections. Presence of EVA was defined as aortic stiffness higher than that predicted from reference values based on the participant's age and blood pressure. The association of preeclampsia with arterial hemodynamic variables was assessed with multivariable linear regression, and the association of severe preeclampsia with EVA was assessed with multivariable logistic regression, adjusted for confounders. We found that women with a history of preeclampsia had greater aortic stiffness, steady arterial load, central blood pressure, and arterial wave reflections when compared with controls. We observed a dose-response relationship, with the greatest abnormalities observed in subgroups with severe, preterm, or recurrent preeclampsia. Women with severe preeclampsia had 9.23 times greater odds of having EVA as compared with controls (95% CI, 1.67-51.06, P=0.011) and 7.87 greater odds of EVA as compared with women with nonsevere preeclampsia (95% CI, 1.29-47.77, P=0.025). Conclusions Our study comprehensively characterizes arterial hemodynamic abnormalities after preeclampsia and suggests that specific subgroups of women with a history of preeclampsia exhibit greater alterations in arterial hemodynamics related to arterial health. Our findings have important implications for understanding potential links between preeclampsia and cardiovascular events, and suggest women with severe, preterm, or recurrent preeclampsia as subgroups who may deserve intensification of efforts for prevention and early detection of cardiovascular disease.

"A natural consequence of aging in women?": a mixed-method exploration on osteoporosis self-efficacy in Turkey.

The purpose of this study to determine the osteoporosis-related self-efficacy levels of women with osteoporosis and investigate the relationship between the characteristics of these women and their osteoporosis self-efficacy. The study was conducted in Siirt province in the Southeastern Anatolia Region of Turkey. A mixed-method approach was selected. Data were collected with 280 surveys and 30 participants' interviews. The mean total OSES score of the participants was 649.82 ± 221.09. Aging, not exercising regularly, inadequate consumption of milk and dairy products, and inadequate exposure to sunlight were significant predictors of low osteoporosis self-efficacy (p < 0.001), explaining 23.4% of the total variance. Knowledge gaps, disease perceptions, facilitators of treatment adherence, and barriers to treatment adherence affected the osteoporosis self-efficacy of the participants. The osteoporosis-related self-efficacy levels of the participants of this study were low. The results suggest that a strategy to organize routine health education programs should be established in order to create a higher perception of osteoporosis self-efficacy in women with osteoporosis and to reduce knowledge gaps and barriers.

INVESTIGATIONS ON OSTEOPOROTIC FRACTURE RISK ASSESSMENT AMONG SOUTH INDIAN WOMEN

Background: Osteoporosis results in an increased risk of fracture among aging women. A strong connection exists for bone health with tooth loss, menopause, diet, BMI and hysterectomy. Purpose: To study the impact of heel BMD with age, BMI, menopausal status, hysterectomy and tooth loss among people living in Chennai metropolitan neighborhood. Materials and Methods: The study involved ([Formula: see text], age: [Formula: see text] years) women, which included women with normal BMD ([Formula: see text] = 35, age: [Formula: see text] years), Osteopenia ([Formula: see text], age: [Formula: see text] years) and Osteoporosis ([Formula: see text], age: [Formula: see text] years). All the participants underwent BMD assessment at their right heel using an Ultrasound densitometer system (Model: CM-200, Manufacturer: FURUNO ELECTRIC CO. LTD., Japan). The subjects were classified into various subgroups based on BMD, age, Menopausal status, hysterectomy and tooth loss. Results: The mean age of women attaining menopause and those undergoing hysterectomy are [Formula: see text] years and [Formula: see text] years, respectively. The decrease of heel BMD was very prominent among women having more than two tooth extracted, menopause and hysterectomy. It was found that approximately 90% of the studied population were suffering from either osteopenia or osteoporosis in their post-menopausal period. Conclusion: Women aged above 50 years are at greater risk of osteoporosis due to post-menopausal phase, high probability of undergoing hysterectomy and tooth loss. Therefore, women should ensure sufficient consumption of calcium rich diet in their entire life cycle to ensure a healthy livelihood.

Connectome-based predictive modeling shows sex differences in brain-based predictors of memory performance.

Alzheimer's disease (AD) takes a more aggressive course in women than men, with higher prevalence and faster progression. Amnestic AD specifically targets the default mode network (DMN), which subserves short-term memory; past research shows relative hyperconnectivity in the posterior DMN in aging women. Higher reliance on this network during memory tasks may contribute to women's elevated AD risk. Here, we applied connectome-based predictive modeling (CPM), a robust linear machine-learning approach, to the Lifespan Human Connectome Project-Aging (HCP-A) dataset (n = 579). We sought to characterize sex-based predictors of memory performance in aging, with particular attention to the DMN. Models were evaluated using cross-validation both across the whole group and for each sex separately. Whole-group models predicted short-term memory performance with accuracies ranging from ρ = 0.21-0.45. The best-performing models were derived from an associative memory task-based scan. Sex-specific models revealed significant differences in connectome-based predictors for men and women. DMN activity contributed more to predicted memory scores in women, while within- and between- visual network activity contributed more to predicted memory scores in men. While men showed more segregation of visual networks, women showed more segregation of the DMN. We demonstrate that women and men recruit different circuitry when performing memory tasks, with women relying more on intra-DMN activity and men relying more on visual circuitry. These findings are consistent with the hypothesis that women draw more heavily upon the DMN for recollective memory, potentially contributing to women's elevated risk of AD.

Sex differences in hippocampal β-amyloid accumulation in the triple-transgenic mouse model of Alzheimer's disease and the potential role of local estrogens.

Epidemiological studies show that women have a higher prevalence of Alzheimer's disease (AD) than men. Peripheral estrogen reduction during aging in women is proposed to play a key role in this sex-associated prevalence, however, the underlying mechanism remains elusive. We previously found that transcription factor early growth response-1 (EGR1) significantly regulates cholinergic function. EGR1 stimulates acetylcholinesterase (AChE) gene expression and is involved in AD pathogenesis. We aimed to investigate whether the triple-transgenic AD (3xTg-AD) mice harboring PS1 M146V , APP Swe , and Tau P301L show sex differences in β-amyloid (Aβ) and hyperphosphorylated tau (p-Tau), the two primary AD hallmarks, and how local 17β-estradiol (E2) may regulate the expression of EGR1 and AChE. We first sacrificed male and female 3xTg-AD mice at 3-4, 7-8, and 11-12 months and measured the levels of Aβ, p-Tau, EGR1, and AChE in the hippocampal complex. Second, we infected SH-SY5Y cells with lentivirus containing the amyloid precursor protein construct C99, cultured with or without E2 administration we measured the levels of extracellular Aβ and intracellular EGR1 and AChE. Female 3xTg-AD mice had higher levels of Aβ compared to males, while no p-Tau was found in either group. In SH-SY5Y cells infected with lentivirus containing the amyloid precursor protein construct C99, we observed significantly increased extracellular Aβ and decreased expression of intracellular EGR1 and AChE. By adding E2 to the culture medium, extracellular Aβ(l-42) was significantly decreased while intracellular EGR1 and AChE expression were elevated. This data shows that the 3xTg-AD mouse model can be useful for studying the human sex differences of AD, but only in regards to Ap. Furthermore, in vitro data shows local E2 may be protective for EGR1 and cholinergic functions in AD while suppressing soluble Aβ(1-42) levels. Altogether, this study provides further in vivo and in vitro data supporting the human epidemiological data indicating a higher prevalence of AD in women is related to changes in brain estrogen levels.

MRI of the pelvic floor in female patients with stress urinary incontinence, pre- and postoperative and/or physiotherapy: analysis of the defect-specific approach

BackgroundStress urinary incontinence (SUI) is a common disabling pelvic floor dysfunction, particularly among aging women. Magnetic resonance imaging (MRI) with dynamic sequences has been proven reliable for detecting pelvic floor weaknesses, especially with multiple compartments defects. Since surgical and non-surgical management options exist, detailed imaging analysis and comprehension of the various surgical and non-surgical interventions are crucial for surgical planning and postoperative evaluation. However, patients often present with recurrent or new symptoms after surgery, where MR imaging is necessary to detect complications in this setting. We aimed to analyze MR images pre- and postoperative/intervention using the defect-specific approach aiming at better understanding of the underlying complication and/or the cause of recurrence.ResultsThirty female patients with SUI were included in the study; 20 underwent surgery, 6 were treated by physiotherapy only, while 3 patients underwent both surgery and physiotherapy and 1 patient was treated conservatively. According to their clinical symptoms, patients with successful surgical/physiotherapy outcome were 18 cases (60%), while unsuccessful group comprised of 12 cases (40%) is classified as follows: persistent complaints subgroup 7 patients (23.3%), de novo complaint subgroup 2 patients (6.7%), while the complicated subgroup is comprised of 2 patients (6.7%) and the persistent/de novo complaints subgroup of the unsuccessful group is composed of 1 case (3.3%). They all underwent MRI of the pelvic floor with a standardized technique, pre- and postoperative/physiotherapy. Changes in level III endopelvic fascia defects between the pre- and postoperative/physiotherapy studies were statistically significant (p = 0.045). Urinary bladder and uterine descent were also found statistically significant between the pre- and postoperative/physiotherapy studies (p = 0.001 and p = 0.029, respectively). Comparing successful and unsuccessful groups pre- and postoperative/therapy, levator plate angle (LPA) was found statistically significant as well (p = 0.039 preoperative and p = 0.001 postoperative).ConclusionsAnalysis of the pre- and postoperative static and dynamic MRI sequences along with proper understanding of the preformed intervention can pinpoint the underlying pathology leading to the recurrent or de novo symptom and/or complications. The defect-specific approach can help determine the underlying pelvic floor defect by altering the MRI techniques tailored for each patient according to their complaint.

The Current Strategy in Hormonal and Non-Hormonal Therapies in Menopause—A Comprehensive Review

Menopause is a natural stage of hormonal aging in women, accompanied by a series of symptoms that reduce the quality of life of a fully active person. As no therapy is entirely satisfactory, the race for a better option is in full swing. Our study objective is to investigate the most recent menopause studies on pharmacological resources, emerging therapies, and the particularities of hormonal replacement therapy (HRT). For this purpose, a comprehensive search was conducted in two main databases (PubMed and Web of Science) guided by the specific keywords "menopause" and "therapy" or "estrogen" or "progesterone" or "hormone replacement" during the last ten years period. Studies were eligible if they met certain criteria: randomized controlled trials (RCT) in adult women with menopause and hormonal or non-hormonal therapies. We selected 62 RCTs, which are focused on four main topics: (a) epidemiology of menopause-related symptoms, (b) hormonal replacement therapy (HRT) selective estrogen receptor modulators, (c) emerging therapies, and (d) menopause. HRT has proven a real health benefit for menopausal women; besides, complementary interventions must be considered. Further studies are needed on menopause and menopause-related therapies. The continuous updating of clinical experience will strengthen the therapeutic benefit and the decision to treat patients safely. This goal will fully access all therapeutic resources to address an unresolved health issue of active adult women.

Human skeletal muscle-specific atrophy with aging: a comprehensive review.

Age-related skeletal muscle atrophy appears to be a muscle group-specific process, yet only a few specific muscles have been investigated and our understanding in this area is limited. This review provides a comprehensive summary of the available information on age-related skeletal muscle atrophy in a muscle-specific manner, nearly half of which comes from the quadriceps. Decline in muscle-specific size over ∼50 yr of aging was determined from 47 cross-sectional studies of 982 young (∼25 yr) and 1,003 old (∼75 yr) individuals and nine muscle groups: elbow extensors (-20%, -0.39%/yr), elbow flexors (-19%, -0.38%/yr), paraspinals (-24%, -0.47%/yr), psoas (-29%, -0.58%/yr), hip adductors (-13%, -0.27%/yr), hamstrings (-19%, -0.39%/yr), quadriceps (-27%, -0.53%/yr), dorsiflexors (-9%, -0.19%/yr), and triceps surae (-14%, -0.28%/yr). Muscle-specific atrophy rate was also determined for each of the subcomponent muscles in the hamstrings, quadriceps, and triceps surae. Of all the muscles included in this review, there was more than a fivefold difference between the least (-6%, -0.13%/yr, soleus) to the most (-33%, -0.66%/yr, rectus femoris) atrophying muscles. Muscle activity level, muscle fiber type, sex, and timeline of the aging process all appeared to have some influence on muscle-specific atrophy. Given the large range of muscle-specific atrophy and the large number of muscles that have not been investigated, more muscle-specific information could expand our understanding of functional deficits that develop with aging and help guide muscle-specific interventions to improve the quality of life of aging women and men.

Accelerated epigenetic aging in women with emotionally unstable personality disorder and a history of suicide attempts

Emotional unstable personality disorder (EUPD; previously borderline personality disorder, BPD) is associated with excess natural-cause mortality, comorbid medical conditions, poor health habits and stress related epigenomic alterations. Previous studies demonstrated that GrimAge – a state-of-the-art epigenetic age (EA) estimator – strongly predicts mortality risk and physiological dysregulation. Herein, we utilize the GrimAge algorithm to investigate whether women with EUPD and a history of recent suicide attempts exhibit EA acceleration (EAA) in comparison to healthy controls. Genome-wide methylation patterns were measured using the Illumina Infinum Methylation Epic BeadChip in whole blood from 97 EUPD patients and 32 healthy controls. The control group was significantly older (p < 0.0001) and reported lesser exposure to violent behavior in both youth and adulthood (p < 0.0001). Groups were otherwise comparable regarding gender, BMI, or tobacco usage (p > 0.05). EA estimator DNAmGrimAge exceeded chronological age by 8.8 and 2.3 years in the EUPD and control group, respectively. Similarly, EAA marker AgeAccelGrim was substantially higher in EUPD subjects when compared to controls, in both univariate and multivariate analyzes (p < 0.00001). Tobacco usage conferred substantial within-group effects on the EA-chronological age difference, i.e., 10.74 years (SD = 4.19) compared to 6.00 years (SD = 3.10) in the non-user EUPD group (p < 0.00001). Notably, past alcohol and substance abuse, use of psychotropic medications, global assessment of functioning, self-reported exposure to violent behavior in youth and adulthood, later completed suicide (N = 8) and age at first suicide attempt did not predict EAA in the EUPD group (p > 0.05). These results underscore the importance of addressing medical health conditions along with low-cost preventative interventions aimed at improving somatic health outcomes in EUPD, such as efforts to support cessation of tobacco use. The independency of GrimAge to other EA algorithms in this group of severely impaired EUPD patients, suggest it may have unique characteristics to evaluate risk of adverse health outcomes in context of psychiatric disorders.

The effect of adverse pregnancy outcomes on vascular aging in young women: the Kailuan study.

Adverse pregnancy outcomes (APOs) are at increased future cardiovascular risk and require effective risk mitigation. However, data regarding appropriate postpartum screening for young women with APOs are lacking. We aimed to investigate the association between APOs and vascular aging by the determination of high pulse wave velocity (PWV) in young women. Women who gave birth from 1990 to 2020 and underwent brachial-ankle pulse wave velocity (baPWV) assessments in the postpartum period were recruited. We excluded women with age ≥50 years at the baPWV assessment or missing postpartum health examinations. The history of APOs including hypertensive disorders of pregnancy, gestational diabetes, preterm delivery, and low birth weight were assessed by medical records. High PWV was defined as baPWV above the 90th percentile for different age group. Multivariable Logistic regression was used to evaluate the association of APOs and high PWV. 3193 participants were included in the analysis, including 912 (28.6%) individuals with APOs. The prevalence of high PWV in the non-APO group and the APOs group were 7.19% (164) and 13.9% (127), respectively (P < 0.05). Compared with non-APO group, the OR (95% CI) of APOs group was 1.67 (1.29-2.16). The risks in the 20-29, 30-39, and 40-49 age groups were 2.51 (1.13-5.59), 1.83 (1.30-2.59), and 1.35 (0.82-2.21) (P for trend <0.05). We conclude that APOs are risk factors of vascular aging for young women and the risk decreased with increasing age. BaPWV should be an important indicator for preventive cardiovascular risk management in young women with APOs.

Lower anti-Müllerian hormone levels are associated with HIV in reproductive age women and shorter leukocyte telomere length among late reproductive age women.

We sought to better understand factors associated with ovarian aging in women with HIV (WWH). HIV has been associated with diminished fertility, younger age at menopause, and shorter leukocyte telomere length (LTL), a marker of cellular aging. We herein examine cross-sectional and longitudinal associations between LTL, anti-Müllerian hormone (AMH), and HIV. We included WWH and HIV-negative women 12-50 years of age in the CARMA cohort with one or more study visit(s). LTL and AMH were measured by qPCR and ELISA, respectively. Women were analyzed in peak reproductive (<35 years) vs. late reproductive (≥35 years) life phases. Using multivariable mixed-effect linear or logistic regressions, we assessed factors associated with AMH and ΔAMH/year while adjusting for relevant confounders. WWH had shorter LTL and lower AMH levels compared to HIV-negative controls despite being of similar age. After adjusting for relevant factors, HIV was associated with 20% lower AMH levels in women under 35 years of age and shorter LTL was associated with AMH levels below 2 ng/ml among women aged 35 years or older. Longitudinally, ΔAMH/year was largely related to initial AMH level among older women, and to age in younger women. Factors associated with AMH change across women's reproductive lifespan. Lower AMH among peak reproductive aged WWH suggests that HIV may have an initial detrimental effect on ovarian reserve, an observation that may warrant counseling around pregnancy planning. In women aged 35 years or older, the association between shorter LTL and lower AMH suggests that the immune and reproductive aging connections are more important in this age group.

International Comparisons of Mortality from Diabetes Mellitus and Other Cardiometabolic Diosorders in The Ontopathogenic Model

Previously we have studied relative morbidity and mortality in Southern region of Brazil, and recently we have compared these parameters with epidemiologic indices of Argentina and Chile. In the present work we have used the database of World Health Organization (WHO), in order to perform direct comparisons of relative or proportional mortality caused by diabetes mellitus and other cardiometabolic disorders in Argentina and 3 European countries: Spain, France and United Kingdom (UK), during the two chronologic periods: 2008-2010 and 2011-2013. It was shown that age-related dynamics of relative mortality from hypertensive disorders was similar in the countries evaluated, however the patterns of such dynamics for diabetes mellitus and ischemic heart diseases were different in Argentina, as compared to 3 European counties evaluated. On the other hand, the calculation of feminine fraction of mortality has shown in all the 4 countries evaluated significant masculine predominance in mortality caused by hypertensive disorders and ischemic heart diseases in the intermediate age categories, as well progressive increase in feminine fraction of relative mortality, beginning from the age category 50-59 years, thus confirming our earlier proposal about accelerated aging of women with the onset of menopause. It is concluded that ontopathogenic model should be elaborated further by means of analyzing different databases including that of WHO, via international comparisons in various regions of the world.

Adverse cardiovascular and metabolic perturbations among older women: 'fat-craving' hearts.

Despite known sex-based differences in cardiovascular aging, differences in aging biology are poorly understood. We hypothesize that circulating metabolites studied cross-sectionally with cardiac aging may be associated with cardiovascular changes that distinguish cardiac aging in women. A population-based cohort of community men and women without cardiovascular disease from Singapore underwent detailed clinical and echocardiography examinations. Cross-sectional associations between cardiac functional characteristics and metabolomics profiles were examined. Five hundred sixty-seven adults (48.9% women) participated. Women were younger (72 ± 4.4years vs 73 ± 4.3years, p = 0.022), had lower diastolic blood pressures (71 ± 11.0mmHg vs 76 ± 11.2mmHg, p < 0.0001, and less likely to have diabetes mellitus (18.0% vs 27.6%, p = 0.013) and smoking (3.8% vs 34.5%, p < 0.001). Body mass indices were similar (24 ± 3.8kg/m2 vs 24 ± 3.4kg/m2, p = 0.29), but women had smaller waist circumferences (81 ± 10.1cm vs 85 ± 9.2cm, p < 0.001). Women had a significantly higher E/e' ratios (10.9 ± 3.4 vs 9.9 ± 3.3, p = 0.007) and mitral A peak (0.86 ± 0.2m/s vs 0.79 ± 0.2m/s, p < 0.001) than men. Among women, lower E/e' ratio was associated with higher levels of C16 (OR 1.019, 95%CI 1.002-1.036, p = 0.029), C16:1 (OR 1.06, 95%CI 1.006-1.118, p = 0.028), serine (OR 1.019, 95%CI 1.002-1.036, p = 0.025), and histidine (OR 1.045, 95%CI 1.013-1.078, p = 0.006). Lower mitral A peak was associated with higher levels of histidine (OR 1.039, 95%CI 1.009-1.070, p = 0.011), isoleucine (OR 1.013, 95%CI 1.004-1.021, p = 0.004), and C20 (OR 1.341, 95%CI 1.067-1.684, p = 0.012). Impairments in diastolic functions were more frequent among older women compared to men, despite lower prevalence of vascular risk factors and preserved cardiac structure. Cardiac aging in women correlated with metabolites involved in fatty acid oxidation and tricyclic acid cycle fuelling.

“She looked ten years older”: Mechanisms of the new Woman's marriage and premature aging under patriarchy in Sarah Grand's The Heavenly Twins

This article examines how the New Woman's premature aging happens in tandem with patriarchal marriage at the fin de siècle through a scrutiny of Sarah Grand's New Woman novel, The Heavenly Twins (1893/1992). The novel is a narrative of female degeneration, in which its three young and married New Woman characters become impuissant to realize the cumbersome feminized ideals of national regeneration and age or die prematurely in their twenties. Their premature decline is caused by moral and sexual degeneration of their military husbands who practice the ideology of progress at the imperial frontier. In the article, I explain how the patriarchal culture of the late Victorian society expedites women's aging process in marriage. The symptoms of mental and physical sickness experienced by the novel's Victorian wives in their twenties are a product not merely of excruciating syphilis but also the patriarchal culture. I ultimately contend that Grand unveils the other side of the male-oriented ideology of progress in criticizing the late Victorian reality where there is negligible scope for the New Woman's vision of female-led regeneration.

Rajonivritti : A Physiological Study

Perimenopause has become an important health issue for women with increasing life expectancy. Most of Perimenopausal women expercience various somatic &amp; Phychological symptoms. Rajonivritti is consider as a normal physiological process in body, which an indication of Jaravastha (ageing) in women's life. Ageing is natural in every individual that is "Nishpratikrya", that mean it cannot be stopped. It this study total 100 women were selected for the evaluation of physiological status of Rajonivritti. These all women divided into two groups, (A) Premenopausal, (B) Post menopausal. The women in whom menstruation stop atleast 12 consecutive months, put into post menopausal class. A Survey questionnaire was prepared for the details about physiology &amp; other information. In this study, it was observed that food-habits, lifestyle, Sleep pattern, Kostha, Agni effect the Rajonivritti. Jara, Vata Vridhi, Pitta Vridhi, Kapha Kshaya, Artava Kshaya etc. all these factors play role in causing symptomatology of perimenopausal syndrome.

Estrogen signaling via estrogen receptor alpha and its implications for neurodegeneration associated with Alzheimer's disease in aging women.

Estrogen receptor alpha (ERα) is a transcription factor activated by estrogenic hormones to regulate gene expression in certain organs, including the brain. In the brain, estrogen signaling pathways are central for maintaining cognitive functions. Herein, we review the neuroprotective effects of estrogens mediated by ERα. The estrogen/ERα pathways are affected by the reduction of estrogens in menopause, and this event may be a risk factor for neurodegeneration associated with Alzheimer's disease in women. Thus, developing a better understanding of estrogen/ERα signaling may be critical for defining new biomarkers and potential therapeutic targets for Alzheimer's disease in women.

Associations of Physical Activity and Sedentary Behavior with Optimism and Positive Affect in Older Women

Psychological well-being is linked to healthy aging in older women, but associations with health behaviors are not well understood. Our study aims to evaluate the relationships between objectively-measured physical behavior (including physical activity and sedentary behavior) with optimism and positive affect in a diverse sample of older women. Our cross-sectional study of 4168 American women (aged 63–99) with accelerometer-measured physical behavior from the Objective Physical Activity and Cardiovascular Health Study assessed associations using multiple linear regression. Effect modification by age, race and ethnicity, social support, and number of chronic conditions was examined as well. In unadjusted models, positive associations for physical activity and negative associations for sedentary behaviors were generally linear for optimism and positive affect. In adjusted models, every one-hour increment in weekly moderate-vigorous physical activity was associated with higher optimism by 0.4 score points [Revised 6-item Life Orientation Test, 95% CI = 0.2, 0.6] and positive affect by 0.6 score points [modified Differential Emotions Scale, 95% CI = 0.2, 0.9]. One-hour increments in light physical activity were associated with higher positive affect [0.2 score points; 95% CI = 0.03, 0.33] while one-hour increments in sedentary behavior patterns were associated with lower positive affect [-0.1 score points; 95% CI = − 0.10, − 0.02). Effect modification by age, race and ethnicity, social support, and number of chronic conditions was not observed. In conclusion, associations between physical behavior with optimism and positive affect were modest but suggest greater activity and less sedentary time are associated with greater psychological well-being in older women.
