Despite overwhelming evidence that vaccines are safe and effective, there has been a rise in vaccine hesitancy and refusal leading to increases in the incidence of communicable diseases. Importantly, ...providing scientific information about the benefits of vaccines has not been effective in counteracting anti-vaccination beliefs. Considering this, better identification of those likely to be vaccine hesitant and the underlying attitudes that predict these beliefs are needed to develop more effective strategies to combat anti-vaccination movements. Focusing on parents as the key decision makers in their children's vaccination, the aim of this study is to better understand the demographic and attitudinal predictors of parental vaccine hesitancy. We recruited 484 parents using Amazon MTurk and queried their attitudes on childhood vaccination, level of education, age, religiosity, political affiliation, trust in medicine, and disgust sensitivity. We found three main demographic predictors for parental vaccine hesitancy: younger age, lower levels of education, and greater religiosity. We also found vaccine hesitant parents to have significantly less trust in physicians and greater disgust sensitivity. These results provide a clearer picture of vaccine hesitant parents and suggest future directions for more targeted research and public health messaging.

Most chronic noncancer pain (CNCP) conditions are more common in women and have been reported to worsen, particularly during the peak reproductive years. This phenomenon suggests that ovarian ...hormones might play a role in modulating CNCP pain. To this end, we reviewed human literature aiming to assess the potential role of ovarian hormones in modulating the following CNCP conditions: musculoskeletal pain, migraine headache, temporal mandibular disorder, and pelvic pain. We found 50 relevant clinical studies, the majority of which demonstrated a correlation between hormone changes or treatments and pain intensity, threshold, or symptoms. Taken together, the findings suggest that changes in hormonal levels may well play a role in modulating the severity of CNCP conditions. However, the lack of consistency in study design, methodology, and interpretation of menstrual cycle phases impedes comparison between the studies. Thus, while the literature is highly suggestive of the role of ovarian hormones in modulating CNCP conditions, serious confounds impede a definitive understanding for most conditions except menstrual migraine and endometriosis. It may be that these inconsistencies and the resulting lack of clarity have contributed to the failure of hormonal effects being translated into medical practice for treatment of CNCP conditions.
Background Despite the widespread use of oral contraceptives (OCs), and the well-documented influence of estrogens, notably 17beta-estradiol (E2), on cognition, research relating OCs to working ...memory is limited and mixed. Two factors may contribute to these mixed findings: 1) pharmacokinetics of oral contraceptives, which drive fluctuations in synthetic hormone levels; and 2) genetic polymorphisms related to dopamine degradation and working memory, which interact with E2. This research investigated whether the pharmacokinetics of oral contraceptives, in concert with the single nucleotide polymorphism (Val.sup.158 Met; rs4680) of the catechol-o-methyltransferase gene (COMT), influence working memory performance. Methods University-age women taking and not taking OCs were tested for working memory and genotyped for COMT. If they were not taking OCs (n = 62), sessions occurred in the early follicular (low E2) and late follicular (high E2) phase. If they were taking OCs (n = 52), sessions occurred 1-2 hours after (high ethinyl estradiol, EE) and ~24 hours after (low EE) pill ingestion. Working memory was tested using the N-back, AX-CPT, Digit Span, and Digit Ordering Tasks. Data were analyzed using multilevel models with estrogen condition, COMT, and group as predictors, controlling for mood and practice effects. Results For women taking OCs, time of pill ingestion did not influence performance. However, the subgroup with COMT val/val (low dopamine) were less accurate on 2-back lure trials than those with COMT met/met (high dopamine). For women not taking OCs, cycle phase moderated COMT's influence on lure accuracy. When compared, women taking OCs had higher AX-CPT proactive control indices than those not taking OCs. Conclusion These findings suggest that oral contraceptives are not detrimental for young women's working memory and that they may increase proactive control. The more pronounced effects of COMT in women taking OCs suggests that, in women taking OCs, suppressed endogenous E2-not fluctuating EE levels-may be more relevant for working memory. Future studies are needed to differentiate effects of endogenous versus synthetic estrogens on working memory.

We investigated the social relations shaping the reproductive health care experiences of women with female genital cutting (FGC) in Toronto, Canada. Using Institutional Ethnography, we interviewed ...eight women with FGC and seven obstetrician/gynecologists (OB/GYN). We found a disjuncture between women's needs during appointments that extended beyond the reproductive body and range of care that doctors were able to provide. Women engaged in emotional healthwork during appointments by explaining FGC to doctors, reading doctors' body language, and getting through vulvar/vaginal examinations. Women reported that if they had emotional reactions during appointments, they were often referred to a mental health specialist, a referral on which they did not act. OB/GYNs described their specialty as "surgical"-training centered around treating reproductive abnormalities and not mental health issues. Therefore, the disjuncture between women's needs and OB/GYNs' institutional training highlights the difficulties inherent when bodies of "difference" encounter the reproductive health care system.

More women have Alzheimer disease (AD) than men, but the reasons for this phenomenon are still unknown. Including women in clinical research and studying their biology is key to understand not just ...their increased risk but also their resilience against the disease. In this sense, women are more affected by AD than men, but their reserve or resilience mechanisms might delay symptom onset. The aim of this review was to explore what is known about mechanisms underlying women's risk and resilience in AD and identify emerging themes in this area that merit further research. We conducted a review of studies analyzing molecular mechanisms that may induce neuroplasticity in women, as well as cognitive and brain reserve. We also analyzed how the loss of steroid hormones in aging may be linked to AD. We included empirical studies with human and animal models, literature reviews as well as meta-analyses. Our search identified the importance of 17-b-estradiol (E2) as a mechanism driving cognitive and brain reserve in women. More broadly, our analysis revealed the following emerging perspectives: (1) the importance of steroid hormones and their effects on both neurons and glia for the study of risk and resilience in AD, (2) E2's crucial role in women's brain reserve, (3) women's verbal memory advantage as a cognitive reserve factor, and (4) E2's potential role in linguistic experiences such as multilingualism and hearing loss. Future directions for research include analyzing the reserve mechanisms of steroid hormones on neuronal and glial plasticity, as well as identifying the links between steroid hormone loss in aging and risk for AD.
Which facets of human spatial navigation do sex and menstrual cycle influence? To answer this question, a cross-sectional online study of reproductive age women and men was conducted in which ...participants were asked to demonstrate and self-report their spatial navigation skills and strategies. Participants self-reported their sex and current menstrual phase early follicular (EF), late follicular/periovulatory (PO), and mid/late luteal (ML), and completed a series of questionnaires and tasks measuring self-reported navigation strategy use, topographical memory, cognitive map formation, face recognition, and path integration. We found that sex influenced self-reported use of cognitive map- and scene-based strategies, face recognition, and path integration. Menstrual phase moderated the influence of sex: compared to men, women had better face recognition and worse path integration, but only during the PO phase; PO women were also better at path integration in the presence of a landmark compared to EF + ML women and men. These findings provide evidence that human spatial navigation varies with the menstrual cycle and suggest that sensitivity of the entorhinal cortex and longitudinal axis of the hippocampus to differential hormonal effects may account for this variation.
Ways in which ovarian hormones affect cognition have been long overlooked despite strong evidence of their effects on the brain. To address this gap, we study performance on a rule-plus-exception ...category learning task, a complex task that requires careful coordination of core cognitive mechanisms, across the menstrual cycle (N = 171). Results show that the menstrual cycle distinctly affects exception learning in a manner that parallels the typical rise and fall of estradiol across the cycle. Participants in their high estradiol phase outperform participants in their low estradiol phase and demonstrate more rapid learning of exceptions than a male comparison group. A likely mechanism underlying this effect is estradiol's impact on pattern separation and completion pathways in the hippocampus. These results provide novel evidence for the effects of the menstrual cycle on category learning, and underscore the importance of considering female sex-related variables in cognitive neuroscience research.
Many of the Somali women who have immigrated to other countries, including Canada, have experienced Female Genital Circumcision/ Mutilation/ Cutting (FGC). While there is literature on the medical ...aspects of FGC, we were interested in understanding the daily life experiences and bodily sensations of Somali-Canadian women in the context of FGC. Fourteen women living in the Greater Toronto Area were interviewed. Interview data were analyzed using a phenomenological approach. We found that the memory of the ceremonial cutting was vivid but was frequently described with acceptance and resignation-as something that just is; that was normal given the particular context, familial and cultural, and their young age. Most of the women recounted experiencing pain and discomfort throughout their adult lives but were intent on not noticing or giving the pain any power; they considered themselves healthy. The following themes emerged from our interviews: Every Body Had It: Discussing FGC, I'm Normal Aren't I?, and Feeling in My Body-all themes that work at normalizing their bodies in a society that they know views them as different. They dealt with both pain and pleasure in the context of their busy lives suggesting resilience in spite of the day-to-day difficulties of daily life.

In this paper, we argue for Gender as a Sociocultural Variable (GASV) as a complement to Sex as a Biological Variable (SABV). Sex (biology) and gender (sociocultural behaviors and attitudes) interact ...to influence health and disease processes across the lifespan-which is currently playing out in the COVID-19 pandemic. This study develops a gender assessment tool-the Stanford Gender-Related Variables for Health Research-for use in clinical and population research, including large-scale health surveys involving diverse Western populations. While analyzing sex as a biological variable is widely mandated, gender as a sociocultural variable is not, largely because the field lacks quantitative tools for analyzing the influence of gender on health outcomes.
We conducted a comprehensive review of English-language measures of gender from 1975 to 2015 to identify variables across three domains: gender norms, gender-related traits, and gender relations. This yielded 11 variables tested with 44 items in three US cross-sectional survey populations: two internet-based (N = 2051; N = 2135) and a patient-research registry (N = 489), conducted between May 2017 and January 2018.
Exploratory and confirmatory factor analyses reduced 11 constructs to 7 gender-related variables: caregiver strain, work strain, independence, risk-taking, emotional intelligence, social support, and discrimination. Regression analyses, adjusted for age, ethnicity, income, education, sex assigned at birth, and self-reported gender identity, identified associations between these gender-related variables and self-rated general health, physical and mental health, and health-risk behaviors.
Our new instrument represents an important step toward developing more comprehensive and precise survey-based measures of gender in relation to health. Our questionnaire is designed to shed light on how specific gender-related behaviors and attitudes contribute to health and disease processes, irrespective of-or in addition to-biological sex and self-reported gender identity. Use of these gender-related variables in experimental studies, such as clinical trials, may also help us understand if gender factors play an important role as treatment-effect modifiers and would thus need to be further considered in treatment decision-making.
Background: Better understanding and addressing health inequities is a growing global priority.
Objective: In this paper, we contribute to the literature examining complex relationships between ...biological and social dimensions in the field of health inequalities. Specifically, we explore the potential of intersectionality to advance current approaches to socio-biological entwinements.
Design: We provide a brief overview of current approaches to combining both biological and social factors in a single study, and then investigate the contributions of an intersectional framework to such work.
Results: We offer a number of concrete examples of how intersectionality has been used empirically to bring both biological and social factors together in the areas of HIV, post-traumatic stress disorder, female genital circumcision/mutilation/cutting, and cardiovascular disease.
Conclusion: We argue that an intersectional approach can further research that integrates biological and social aspects of human lives and human health and ultimately generate better and more precise evidence for effective policies and practices aimed at tackling health inequities.
