Recent guidelines for the Medical Student Performance Evaluation (MSPE) have standardized the "dean's letter." The authors examined MSPEs for linguistic differences according to student or author gender. This 2009 study analyzed 297 MSPEs for 227 male and 70 female medical students applying to a diagnostic radiology residency program. Text analysis software identified word counts, categories, frequencies, and contexts; factor analysis detected patterns of word categories in student-author gender pairings. Analyses showed a main effect for student gender (P=.046) and a group difference for the author-student gender combinations (P=.048). Female authors of male student MSPEs used the fewest "positive emotion" words (P=.006). MSPEs by male authors were shorter than those by females (P=.014). MSPEs for students ranked in the National Resident Matching Program contained more "standout" (P=.002) and "positive emotion" (P=.001) words. There were no differences in the author-gender pairs in the proportion of students ranked, although predominant word categories differed by author and student gender. Factor analysis revealed differences among the author-student groups in patterns of correlations among word categories. MSPEs differed slightly but significantly by student and author gender. These differences may derive from societal norms for male and female behaviors and the subsequent linguistic interpretation of these behaviors, which itself may be colored by the observer's gender. Although the differences in MSPEs did not seem to influence students' rankings, this work underscores the need for awareness of the complex effects of gender in evaluating students and guiding their specialty choices.

Gender identification is one of the major problem speech analysis today. Tracing the gender from acoustic data i.e., pitch, median, frequency etc. Machine learning gives promising results for classification problem in all the research domains. There are several performance metrics to evaluate algorithms of an area. Our Comparative model algorithm for evaluating 5 different machine learning algorithms based on eight different metrics in gender classification from acoustic data. Agenda is to identify gender, with five different algorithms: Linear Discriminant Analysis (LDA), K-Nearest Neighbour (KNN), Classification and Regression Trees (CART), Random Forest (RF), and Support Vector Machine (SVM) on basis of eight different metrics. The main parameter in evaluating any algorithms is its performance. Misclassification rate must be less in classification problems, which says that the accuracy rate must be high. Location and gender of the person have become very crucial in economic markets in the form of AdSense. Here with this comparative model algorithm, we are trying to assess the different ML algorithms and find the best fit for gender classification of acoustic data.
Gendered health inequalities in mental well-being? The Nordic countries in a comparative perspective.

PubMed

Olafsdottir, Sigrun

2017-03-01

The aims of this study were to: (a) compare gender differences in mental well-being in the Nordic countries with gender differences in 28 other countries around the world; and (b) evaluate whether gender differences in the Nordic countries remain when other social and lifestyle factors are taken into account. Data were obtained from 32 countries around the world that participated in the 2011 health module of the International Social Survey Programme. Ordered logit regression models were used to evaluate whether gender differences remained significant when other social and lifestyle factors were considered. Gender differences in mental well-being in the Nordic countries are not particularly small and the four countries do not cluster together. The gender differences remain when other social and lifestyle factors are taken into account. There appears to be a similar Nordic health paradox for mental well-being outcomes as for physical health outcomes. Although there may be multiple reasons for this, continued gender equality, including sex segregation in the labour market and gendered expectations, are considered to play a part.

The aim of this study was to assess adolescents' evaluations of, and reasoning about, gender stereotypes in video games. Female (N = 46) and male (N = 41), predominantly European-American, mean age = 19 years, were interviewed about their knowledge of game usage, awareness and evaluation of stereotypes, beliefs about the influences of games on the players, and authority jurisdiction over 3 different types of games: games with negative male stereotypes, and games with negative female stereotypes, and gender-neutral games. Gender differences were found for how participants evaluated these games. Males were more likely than females to find stereotypes acceptable. Results are discussed in terms of social reasoning, video game playing, and gender differences. PMID:25722501

The impact of gender stereotypes on the evaluation of general practitioners' communication skills: an experimental study using transcripts of physician-patient encounters.

2007-12-01

The present study has been designed to test for the effect of physicians' gender on the perception and assessment of empathic communication in medical encounters. Eighty-eight volunteers were asked to assess six transcribed interactions between physicians and a standardized patient. The effects of physicians' gender were tested by the experimental manipulation of physicians' gender labels in transcripts. Participants were randomly assigned to one of two testing conditions: (1) perceived gender corresponds to the physician's true gender; (2) perceived gender differs from the physician's true gender. Empathic communication was assessed using the Rating Scales for the Assessment of Empathic Communication in Medical Interviews. A 2 (physician's true gender: female vs. male)x2 (physician's perceived gender: female vs. male)x2 (rater's gender: female vs. male) mixed multivariate analysis of variance (MANOVA) yielded a main effect for physician's true gender. Female physicians were rated higher on empathic communication than male physicians irrespective of any gender labels. The present findings suggest that gender differences in the perception of physician's empathy are not merely a function of the gender label. These findings provide evidence for differences in male and female physicians' empathic communication that cannot be attributed to stereotype bias. Future efforts to evaluate communication skills training for general practitioners may consider gender differences.
Gender Differences in the Structure of Marital Quality.

Marriages consist of shared experiences and interactions between husbands and wives that may lead to different impressions of the quality of the relationship. Few studies, unfortunately, have tested gender differences in the structure of marital quality, and even fewer studies have evaluated whether genetic and environmental influences on marital quality differ across gender. In this study, we evaluated gender differences in the structure of marital quality using independent samples of married male (n = 2406) and married female (n = 2215) participants from the National Survey of Midlife Development in the United States who provided ratings on twenty-eight marital quality items encompassing six marital quality constructs. We further explored gender differences in genetic and environmental influences on marital quality constructs in a subsample of 491 pairs of twins. Results suggest partial metric invariance across gender but structural variability in marital quality constructs. Notably, correlations between constructs were stronger in women than men. Results also support gender differences in the genetic and environmental influences on different aspects of marital quality. We discuss that men and women may approach and react to marriage differently as the primary reason why we observed differences in the structure of marital quality.
[Gender: new methodological approaches in guideline development].

Gender and diversity have a strong impact on health and illness as evidenced by sex and gender differences in the onset and progression of diseases as well as in diagnosis, therapy, and therapeutic outcome. The number of sex/gender-specific studies in medicine has increased steadily in recent years, indicating sex (biological) and gender (social) differences in numerous diseases. Despite this evidence, however, sex/gender differences are rarely considered in medical practice or in health systems, suggesting a delay in transferring such research into evidence-based medical treatment. Similarly, quality improvement guidelines in medical care do not systematically integrate the sex/gender perspective. Against this backdrop, this paper seeks to enumerate the necessary components of a guideline development and evaluation process that systematically integrates sex/gender differences in addition to providing a sex/gender-based methodological approach. The latter is illustrated by a pilot study in which four international guidelines on depression were selected. The sex/gender appropriateness of these guidelines was analysed using two methods: first, sex/gender-relevant words were counted; and second, relevant sex/gender differences were summarised based on a systematic literature review and then compared with the information given in the guidelines. The findings of the pilot study revealed that although strong evidence exists on sex/gender differences in depression, such research was rarely implemented in the guidelines. Given the scope and potential of guidelines to improve the quality of health care, it is essential that they consider the crucial role of sex/gender differences. To date, sex/gender differences have been insufficiently addressed in guideline development and evaluation when they should be an integral component of the process. Copyright © 2010.

During the last decades, sex and gender biases have been identified in various areas of biomedical and public health research, leading to compromised validity of research findings. As a response, methodological requirements were developed but these are rarely translated into research practice. The aim of this study is to provide good practice examples of sex/gender sensitive health research. We conducted a systematic search of research articles published in JECH between 2006 and 2014. An instrument was constructed to evaluate sex/gender sensitivity in four stages of the research process (background, study design, statistical analysis, discussion). In total, 37 articles covering diverse topics were included. Thereof, 22 were evaluated as good practice example in at least one stage; two articles achieved highest ratings across all stages. Good examples of the background referred to available knowledge on sex/gender differences and sex/gender informed theoretical frameworks. Related to the study design, good examples calculated sample sizes to be able to detect sex/gender differences, selected sex/gender sensitive outcome/exposure indicators, or chose different cut-off values for male and female participants. Good examples of statistical analyses used interaction terms with sex/gender or different shapes of the estimated relationship for men and women. Examples of good discussions interpreted their findings related to social and biological explanatory models or questioned the statistical methods used to detect sex/gender differences. The identified good practice examples may inspire researchers to critically reflect on the relevance of sex/gender issues of their studies and help them to translate methodological recommendations of sex/gender sensitivity into research practice.

This thesis is part of the studies of gender bias in health which together with the paradigm of evidence-based medicine shares the empirical assumption that there are inaccuracies in medical practice, in addition to a lack of rigour and transparency. It worked with the distinction between the concepts of sex and gender and between the concepts of sex-related differences and gender inequalities, in terms of applying a gender perspective in the study design and the subsequent analysis. This PhD review presents the research process conducted in Spain, which can provide an example for future research. Study I described a review of 58 clinical trials (CTs) of etoricoxib to assess its compliance with the Recommendations of Evaluation of Gender Differences in the Clinical Evaluation of Drugs. In Study II, key informants from professions related to different areas in drug development and pharmacovigilance held a working meeting to reach a consensus document on recommendations for the study and evaluation of gender differences in CTs in Spain. In Study III, the websites of the eight best-selling hormone replacement therapy drugs in Spain on Google first page of results were analysed. In Study IV, a logistic regression analysis was performed to compare analgesic prescription by sex in regions with a higher or lower Gender Development Index (GDI) than the Spanish average. Gender biases identified in this thesis limited the legitimacy of medicine, which is not based on the best possible evidence. The results also demonstrate the existence of inequalities between men and women that are not due merely to biological differences, but are gender inequalities stemming from the social differences that exist between both sexes.

Justice research examining gender differences has yielded contrasting findings. This study enlists advanced techniques in cognitive neuroscience (fMRI) to examine gender differences in brain activation patterns in response to procedural and distributive justice manipulations. We integrate social role, information processing, justice, and neuroscience literature to posit and test for gender differences in 2 neural subsystems known to be involved in the appraisal of self-relevant events. Results indicate that the relationship between justice information processing and neural activity in areas representing these subsystems is significantly influenced by gender, with greater activation for females than males during consideration of both procedural and distributive justice information. In addition, we find evidence that gender and distributive injustice interact to influence bargaining behavior, with females rejecting ultimatum game offers more frequently than males. Results also demonstrate activation in the ventromedial prefrontal cortex (vmPFC) and ventral striatum brain regions during procedural justice evaluation is associated with offer rejection in females, but not in males. Managerial implications based on the study's support for gender differences in justice perceptions are discussed. (c) 2016 APA, all rights reserved).
Gender differences in resource use and evaluation of attributes of places of resource use by Native Americans and Caucasians from Western Idaho: relevance to risk evaluations.

A substantial body of literature deals with exposure differences between men and women, and how men and women perceive environmental risk, but far less attention has been devoted to how men and women use the environment and how they evaluate the features of natural environments. The objective of this study was to examine gender differences in the perceptions of environmental quality and resource use for Native Americans and Caucasians interviewed at an Indian festival in northwestern Idaho. More individuals engaged in fishing than any other consumptive activity, and more people engaged in camping and hiking than other nonconsumptive activities. For both ethnic groups, significantly more men hunted than women, although a higher percentage of Native Americans of both genders hunted than did Caucasians. Although significantly more Caucasian men fished than women (63 vs. 41%), there were no marked differences in fishing for Native Americans. Significantly more Native American women gathered herbs (57%) compared to men (37%). There were no significant gender differences in nonconsumptive activities (camping, hiking, biking, bird watching, or picnicking). For those who engaged in consumptive and nonconsumptive activities, however, there were few gender differences in the frequency of these activities, except for fishing, hunting, and crabbing by Caucasians (men had higher rates) and collecting berries and herbs for Native Americans (women had higher rates). When asked to evaluate environmental characteristics or attributes on a scale of 1 (less important) to 5 (very important), unpolluted water, clean air, no visible smog, unpolluted groundwater, and appears unspoiled were rated the highest. There were few significant gender differences in these evaluations for Native Americans, but there were significant gender differences for Caucasians: Women rated most features higher than did men (except for natural tidal flow). These data indicate a need to evaluate not only consumption rate differences between men and women, but also nonconsumptive activities, as well as resource values and perceptions, when managing environments and determining potential risk from exposure.

Little attention has been given to gender differences in respiratory health, particularly in occupational settings. The purpose of this paper was to evaluate gender differences in respiratory morbidity based on surveys of hospitality workers, radiographers, and respiratory therapists. Data were available from mail surveys of 850 hospitality industry workers (participation rate 73.9%; 52.6% female), 586 radiographers (participation rate 63.6%; 85% female), and 275 respiratory therapists (participation rate 64.1%; 58.6% female). Cross-tabulations by gender were evaluated by chi(2) analysis and logistic regression with adjustment for personal and work characteristics. Women consistently had greater respiratory morbidity for symptoms associated with shortness of breath, whereas men usually had a higher prevalence of phlegm. There were few differences in work exposures apart from perception of exposure to ETS among hospitality workers. Gender differences in symptoms were often reduced after adjustment for personal and work characteristics but for respiratory therapists there were even greater gender disparities for asthma attack and breathing trouble. Population health findings of elevated symptoms among women were only partially supported by these occupational respiratory health surveys. The influence of differential exposures and personal factors should be considered when interpreting gender differences in health outcomes.

Personality and gender differences in global perspective.

Men's and women's personalities appear to differ in several respects. Social role theories of development assume gender differences result primarily from perceived gender roles, gender socialization and sociostructural power differentials. As a consequence, social role theorists expect gender differences in personality to be smaller in cultures with more gender egalitarianism. Several large cross-cultural studies have generated sufficient data for evaluating these global personality predictions. Empirically, evidence suggests gender differences in most aspects of personality-Big Five traits, Dark Triad traits, self-esteem, subjective well-being, depression and values-are conspicuously larger in cultures with more egalitarian gender roles, gender socialization and sociopolitical gender equity. Similar patterns are evident when examining objectively measured attributes such as tested cognitive abilities and physical traits such as height and blood pressure. Social role theory appears inadequate for explaining some of the observed cultural variations in men's and women's personalities. Evolutionary theories regarding ecologically-evoked gender differences are described that may prove more useful in explaining global variation in human personality. © 2016 International Union of Psychological Science.

Gender equality in couples and self-rated health - A survey study evaluating measurements of gender equality and its impact on health.

Men and women have different patterns of health. These differences between the sexes present a challenge to the field of public health. The question why women experience more health problems than men despite their longevity has been discussed extensively, with both social and biological theories being offered as plausible explanations. In this article, we focus on how gender equality in a partnership might be associated with the respondents' perceptions of health. This study was a cross-sectional survey with 1400 respondents. We measured gender equality using two different measures: 1) a self-reported gender equality index, and 2) a self-perceived gender equality question. The aim of comparison of the self-reported gender equality index with the self-perceived gender equality question was to reveal possible disagreements between the normative discourse on gender equality and daily practice in couple relationships. We then evaluated the association with health, measured as self-rated health (SRH). With SRH dichotomized into 'good' and 'poor', logistic regression was used to assess factors associated with the outcome. For the comparison between the self-reported gender equality index and self-perceived gender equality, kappa statistics were used. Associations between gender equality and health found in this study vary with the type of gender equality measurement. Overall, we found little agreement between the self-reported gender equality index and self-perceived gender equality. Further, the patterns of agreement between self-perceived and self-reported gender equality were quite different for men and women: men perceived greater gender equality than they reported in the index, while women perceived less gender equality than they reported. The associations to health were depending on gender equality measurement used. Men and women perceive and report gender equality differently. This means that it is necessary not only to be conscious of the methods and measurements used to quantify men's and women's opinions of gender equality, but also to be aware of the implications for health outcomes.

Clinical performance evaluations are major components of medical school clerkship grades. But are they sufficiently objective? This study aimed to determine whether student and evaluator gender is associated with assessment of overall clinical performance. This was a retrospective analysis of 4,272 core clerkship clinical performance evaluations by 829 evaluators of 155 third-year students, within the Alpert Medical School grading database for the 2013-2014 academic year. Overall clinical performance, assessed on a three-point scale (meets expectations, above expectations, exceptional), was extracted from each evaluation, as well as evaluator gender, age, training level, department, student gender and age, and length of observation time. Hierarchical ordinal regression modeling was conducted to account for clustering of evaluations. Female students were more likely to receive a better grade than males (adjusted odds ratio [AOR] 1.30, 95% confidence interval [CI] 1.13-1.50), and female evaluators awarded lower grades than males (AOR 0.72, 95% CI 0.55-0.93), adjusting for department, observation time, and student and evaluator age. The interaction between student and evaluator gender was significant (P = .03), with female evaluators assigning higher grades to female students, while male evaluators' grading did not differ by student gender. Students who spent a short time with evaluators were also more likely to get a lower grade. A one-year examination of all third-year clerkship clinical performance evaluations at a single institution revealed that male and female evaluators rated male and female students differently, even when accounting for other measured variables.

Four 50 meter male/female finals - the freestyle, butterfly, breaststroke, and backstroke - swum during individual events at the Swimming World Championships (SWCs) can be defined in four clusters. The aim of the present study was to use a single-unit design structure, in which the swimmer was defined at only one scale, to evaluate gender differences in start reaction times among elite swimmers in 50 m events. The top six male and female swimmers in the finals of four swimming stroke final events in six SWCs were analyzed. An unpaired t-test was used. The p-values were evaluated using Neo-Fisherian significance assessments (Hurlbert and Lombardi, 2012). For the freestyle, gender differences in the start reaction times were positively identified for five of the six SWCs. For the backstroke, gender differences in the start reaction times could be dismissed for five of the six SWCs. For both the butterfly and breaststroke, gender differences in the start reaction times yielded inconsistent statistical differences. Pooling all swimmers together (df = 286) showed that an overall gender difference in the start reaction times could be positively identified: p = 0.00004. The contrast between the gender differences in start reaction times between the freestyle and backstroke may be associated with different types of gender adaptations to swimming performances. When the natural groupings of swimming stroke final events were ignored, sacrificial pseudoreplication occurred, which may lead to erroneous statistical differences. PMID:25414754

OBJECTIVE To analyze whether gender influence survival results of kidney transplant grafts and patients. METHODS Systematic review with meta-analysis of cohort studies available on Medline (PubMed), LILACS, CENTRAL, and Embase databases, including manual searching and in the grey literature. The selection of studies and the collection of data were conducted twice by independent reviewers, and disagreements were settled by a third reviewer. Graft and patient survival rates were evaluated as effectiveness measurements. Meta-analysis was conducted with the Review Manager® 5.2 software, through the application of a random effects model. Recipient, donor, and donor-recipient gender comparisons were evaluated. RESULTS : Twenty-nine studies involving 765,753 patients were included. Regarding graft survival, those from male donors were observed to have longer survival rates as compared to the ones from female donors, only regarding a 10-year follow-up period. Comparison between recipient genders was not found to have significant differences on any evaluated follow-up periods. In the evaluation between donor-recipient genders, male donor-male recipient transplants were favored in a statistically significant way. No statistically significant differences were observed in regards to patient survival for gender comparisons in all follow-up periods evaluated. CONCLUSIONS The quantitative analysis of the studies suggests that donor or recipient genders, when evaluated isolatedly, do not influence patient or graft survival rates. However, the combination between donor-recipient genders may be a determining factor for graft survival. PMID:26465666

Whereas it is often stated that aging might have more negative consequences for the evaluation of women compared to men, evidence for this assumption is mixed. We took a differentiated look at age stereotypes of men and women, assuming that the life domain in which older persons are rated moderates gender differences in age stereotypes. A sample of 298 participants aged 20-92 rated 65 - year-old men and women on evaluative statements in eight different life domains. Furthermore, perceptions of gender- and domain-specific age-related changes were assessed by comparing the older targets to 45 - year-old men and women, respectively. The results speak in favor of the domain specificity of evaluative asymmetries in age stereotypes for men and women, and imply that an understanding of gendered perceptions of aging requires taking into account the complexities of domain-specific views on aging.

Feminist theory uses gender as a lens to evaluate society's institutions and power hierarchies. Gender evolves as a social construction rather than an essential difference between the sexes, and it supports the so-called "hegemony of dominant men" in society. Socialization by gender enables discrimination in gender roles and occupations, and its…

More and more frequently, the registration of life satisfaction is being used to evaluate different medical treatments. So far, there have been only few such surveys on transsexuals (TS). Therefore, the aim of this study was to evaluate the general and the health-related life satisfaction of transsexuals after gender transformation operations. Forty patients took part in this German cross-sectional study. The Questions on Life Satisfaction Module (FLZ) and free questions on different aspects of the new gender identity were used as measuring instruments. Of the TS studied, 85-95% were "very satisfied" or "satisfied" with the results of their gender transformation operation in respect to gender identity. The TS were significantly less satisfied (P>0.001) in overall "general life satisfaction" than the general population. In overall FLZ scores for "health-related life satisfaction", no differences were seen. These data indicate a discrepancy between subjective satisfaction with new gender identity and current life situation, and they identify problems with life satisfaction.

Gender equality in couples and self-rated health - A survey study evaluating measurements of gender equality and its impact on health

PubMed Central

2011-01-01

Background Men and women have different patterns of health. These differences between the sexes present a challenge to the field of public health. The question why women experience more health problems than men despite their longevity has been discussed extensively, with both social and biological theories being offered as plausible explanations. In this article, we focus on how gender equality in a partnership might be associated with the respondents' perceptions of health. Methods This study was a cross-sectional survey with 1400 respondents. We measured gender equality using two different measures: 1) a self-reported gender equality index, and 2) a self-perceived gender equality question. The aim of comparison of the self-reported gender equality index with the self-perceived gender equality question was to reveal possible disagreements between the normative discourse on gender equality and daily practice in couple relationships. We then evaluated the association with health, measured as self-rated health (SRH). With SRH dichotomized into 'good' and 'poor', logistic regression was used to assess factors associated with the outcome. For the comparison between the self-reported gender equality index and self-perceived gender equality, kappa statistics were used. Results Associations between gender equality and health found in this study vary with the type of gender equality measurement. Overall, we found little agreement between the self-reported gender equality index and self-perceived gender equality. Further, the patterns of agreement between self-perceived and self-reported gender equality were quite different for men and women: men perceived greater gender equality than they reported in the index, while women perceived less gender equality than they reported. The associations to health were depending on gender equality measurement used. Conclusions Men and women perceive and report gender equality differently. This means that it is necessary not only to be conscious of the methods and measurements used to quantify men's and women's opinions of gender equality, but also to be aware of the implications for health outcomes.

2005-04-01

The aim of this study was to evaluate the extent to which gender and other factors predict the severity of online gaming addiction among Taiwanese adolescents. A total of 395 junior high school students were recruited for evaluation of their experiences playing online games. Severity of addiction, behavioral characteristics, number of stressors, and level of satisfaction with daily life were compared between males and females who had previously played online games. Multiple regression analysis was used to explore gender differences in the relationships between severity of online gaming addiction and a number of variables. This study found that subjects who had previously played online games were predominantly male. Gender differences were also found in the severity of online gaming addiction and motives for playing. Older age, lower self-esteem, and lower satisfaction with daily life were associated with more severe addiction among males, but not among females. Special strategies accounting for gender differences must be implemented to prevent adolescents with risk factors from becoming addicted to online gaming.

2015-05-01

Research on gender and workplace decision-making tends to address either supply-side disparities between men's and women's human and social capital, or demand-side differences in the status expectations of women and men workers. In addition, this work often relies on causal inferences drawn from empirical data collected on worker characteristics and their workplace outcomes. In this study, we demonstrate how tangible education and work history credentials - typically associated with supply-side characteristics - work in tandem with cultural beliefs about gender to influence the evaluative process that underlies venture capital decisions made in high-growth, high-tech entrepreneurship. Using an experimental design, we simulate funding decisions by venture capitalists (VCs) for men and women entrepreneurs that differ in technical background and the presence of important social ties. We demonstrate the presence of two distinct aspects of VCs' evaluation: that of the venture and that of the entrepreneur, and find that the gender of the entrepreneur influences evaluations most when the person, rather than the venture, is the target of evaluation. Technical background qualifications moderate the influence of gendered expectations, and women receive more of a payoff than men from having a close contact to the evaluating VC. We discuss the implications for future research on gender and work. Copyright © 2014 Elsevier Inc. All rights reserved.
Impact of Gender-Specific Human Papillomavirus Vaccine Recommendations on Uptake of Other Adolescent Vaccines: Analysis of the NIS-Teen (2008-2012).

PubMed

Bednarczyk, Robert A; Orenstein, Walter A; Omer, Saad B

In the United States, human papillomavirus vaccination was routinely recommended for adolescent females in 2006 and provisionally recommended for adolescent males in 2009. We evaluated the hypothesis that gender-specific human papillomavirus vaccination recommendations would impact gender-specific uptake of other vaccines using National Immunization Survey-Teen public use data sets (2008-2012). Female adolescents had higher coverage than males of at least 1 other adolescent vaccine in 2008 (3.0% higher) and 2009 (4.3% higher). Gender differences abated in 2010, 2011, and 2012 (0.2%, 0.9%, and 0.4%, respectively). To evaluate unintended consequences of gender-based recommendations, countries with female-only human papillomavirus vaccination recommendations should evaluate gender-specific uptake of other adolescent vaccines.
Gender Role Violations and the Sexual Double Standard.

PubMed

Zaikman, Yuliana; Marks, Michael J; Young, Tara M; Zeiber, Jacqueline A

2016-12-01

The sexual double standard (SDS) suggests that women are evaluated negatively and men positively for engaging in similar sexual behaviors. According to social role theory, the SDS exists due to gender role structures. Consequently, perceived violations of women's sexual behavior are associated with the SDS. In addition to gender role violations of sexual behavior, two additional violations of gender roles exist: heterosexual sexual orientation norms and gender role characteristics. The current study aims to investigate whether the SDS persists for sexual orientation-violating and gender role characteristic-violating targets, and to examine which of the three gender role violations influence evaluations of others' sexual behavior. A U.S. sample of 483 participants evaluated target individuals who were either female or male, heterosexual/gay man or lesbian, feminine or masculine, and had 1 or 12 sexual partners. Results indicate that SDS persists for gender role-violating targets but is exhibited differently for targets violating heterosexual sexual orientation norms and gender role characteristics.

Previous studies reported conflicting results concerning different pain perceptions of men and women. Recent research found higher pain levels in men after major surgery, contrasted by women after minor procedures. This trial investigates differences in self-reported preoperative pain intensity between genders before surgery.Patients were enrolled in 2011 and 2012 presenting for preoperative evaluation at the anesthesiological assessment clinic at Charité University hospital. Out of 5102 patients completing a computer-assisted self-assessment, 3042 surgical patients with any preoperative pain were included into this prospective observational clinical study. Preoperative pain intensity (0-100 VAS, visual analog scale) was evaluated integrating psychological cofactors into analysis.Women reported higher preoperative pain intensity than men with median VAS scores of 30 (25th-75th percentiles: 10-52) versus 21 (10-46) (P < 0.001). Adjusted multiple regression analysis showed that female gender remained statistically significantly associated with higher pain intensity (P < 0.001). Gender differences were consistent across several subgroups especially with varying patterns in elderly. Women scheduled for minor and moderate surgical procedures showed largest differences in overall pain compared to men.This large clinical study observed significantly higher preoperative pain intensity in female surgical patients. This gender difference was larger in the elderly potentially contradicting the current hypothesis of a primary sex-hormone derived effect. The observed variability in specific patient subgroups may help to explain heterogeneous findings of previous studies.

Investigating gender differences in alcohol problems: a latent trait modeling approach.

PubMed

Nichol, Penny E; Krueger, Robert F; Iacono, William G

2007-05-01

Inconsistent results have been found in research investigating gender differences in alcohol problems. Previous studies of gender differences used a wide range of methodological techniques, as well as limited assortments of alcohol problems. Parents (1,348 men and 1,402 women) of twins enrolled in the Minnesota Twin Family Study answered questions about a wide range of alcohol problems. A latent trait modeling technique was used to evaluate gender differences in the probability of endorsement at the problem level and for the overall 105-problem scale. Of the 34 problems that showed significant gender differences, 29 were more likely to be endorsed by men than women with equivalent overall alcohol problem levels. These male-oriented symptoms included measures of heavy drinking, duration of drinking, tolerance, and acting out behaviors. Nineteen symptoms were denoted for removal to create a scale that favored neither gender in assessment. Significant gender differences were found in approximately one-third of the symptoms assessed and in the overall scale. Further examination of the nature of gender differences in alcohol problem symptoms should be undertaken to investigate whether a gender-neutral scale should be created or if men and women should be assessed with separate criteria for alcohol dependence and abuse.

Background Patient understanding of advanced metastatic disease is central to decisions about care near death. Prior studies have focused on gender differences in communication style rather than on illness understanding. Objectives To evaluate gender differences in terminal illness acknowledgement (TIA), understanding that the disease is incurable and the advanced stage of the disease. To evaluate gender differences in patients’ reports of discussions of life expectancy with oncology providers and its effect on differences in illness understanding. Methods Coping with Cancer 2 patients (N = 68) were interviewed before and after a visit with their oncology providers to discuss scan results. Results At the prescan interview, there were no statistically significant gender differences in patient measures of illness understanding. At the postscan interview, women were more likely than men to recognize that their illness was incurable (Adjusted Odds Ratio, [AOR] = 5.29; P = .038), know that their cancer was at an advanced stage (AOR = 6.38; P = .013), and report having had discussions of life expectancy with their oncologist (AOR = 4.77; P = .021). Controlling discussions of life expectancy, women were more likely than men to report that their cancer was at an advanced stage (AOR = 9.53; P = .050). Controlling for gender, discussions of life expectancy were associated with higher rates of TIA (AOR = 4.65; P = .036) and higher rates of understanding that the cancer was incurable (AOR = 4.09; P = .085). Conclusions Due largely to gender differences in communication, women over time have a better understanding of their illness than men. More frequent discussions of life expectancy should enhance illness understanding and reduce gender differences. PMID:24400392

When evaluating gender differences in mental disorders and suicidality, specifically between European countries, studies are sparse and frequently hindered by methodological issues, such as the limited items evaluated and inconsistent sampling designs. In ten European countries participating in the World Mental Health Survey Initiative, lifetime internalizing and externalizing disorders and suicidality were assessed among 37,289 respondents. Disorders were classified using DMS-IV criteria. Odds ratios (OR) for gender differences were calculated using logistic regression, while trends across age-groups were tested via gender × age interaction. Within countries, prevalence of any lifetime internalizing disorder ranged from 10.8% to 44.5% among women and 5.9% to 26.5% among men, with women having consistently higher odds than men (OR range: 1.52-2.73). Prevalence of any lifetime externalizing disorders ranged from 0.2% to 6.6% among women and 2.2% to 22.4% among men, with women having consistently lower odds than men (OR range: 0.05-0.35). Any lifetime suicide attempt was found in 0.8-5.4% of women and 0.3-2.4% of men, showing inconsistent relative gender-differences across countries (OR range: 0.77-4.72). Significant effects in gender OR across age-groups were not observed for any internalizing disorder or suicide attempt, yet were present for any externalizing disorder in France (p = 0.01), the Netherlands (p = 0.05), and Spain (p = 0.02). Mental disorders were assessed with the CIDI 3.0 and not psychiatric evaluations. Suicidality does not fully represent more important clinical events, such as suicide mortality. Consistent across European countries, internalizing disorders are more common among women and externalizing disorders among men, whereas gender differences in suicidality varied.

2008-06-01

This study evaluated the association between Internet addiction and frustration intolerance, the gender difference of frustration intolerance, and the gender differences of the association between Internet addiction and frustration intolerance. Participants were 2,114 students (1,204 male and 910 female) who were recruited to complete the Chen Internet Addiction Scale and Frustration Discomfort scale. Females had higher scores on the subscale of entitlement and emotional intolerance and the total scale of the frustration intolerance. There was a significant gender difference on the association between Internet addiction and frustration intolerance. The association was higher in male adolescents. Regression analysis revealed male adolescents with Internet addiction had higher intolerance to frustration of entitlement and emotional discomfort, and female adolescents with it had higher intolerance to emotional discomfort and lower tolerance to frustration of achievement. Frustration intolerance should be evaluated for adolescents with Internet addiction, especially for males. Rational emotive behavior therapy focusing on different irrational beliefs should be provided to male and female adolescents with Internet addiction.
The impact of gender on asthma in the daily clinical practice.

Ciprandi, Giorgio; Gallo, Fabio

2018-03-01

It is up-to-date to consider the potential gender impact on a disease. There are few data about gender difference in asthma. Therefore, the present cross-sectional study tested this hypothesis in a real-life setting to investigate possible difference between genders. This study was cross-sectional, considering 554 consecutive outpatients suspected of asthma, who were referred for a first specialist visit. Clinical and functional parameters were evaluated. Females with asthma could have a worse perception of asthma control, assessed by asthma control test (ACT), and more anxiety than asthmatic males. However, there was no difference regarding asthma control grading, asthma severity, and asthma medication use between genders; the differences in lung function were without clinical relevance. In the daily clinical practice, it is relevant to consider gender in the management of asthma.

One of the challenging biometric authentication applications is gender identification and age classification, which captures gait from far distance and analyze physical information of the subject such as gender, race and emotional state of the subject. It is found that most of the gender identification techniques have focused only with frontal pose of different human subject, image size and type of database used in the process. The study also classifies different feature extraction process such as, Principal Component Analysis (PCA) and Local Directional Pattern (LDP) that are used to extract the authentication features of a person. This paper aims to analyze different gender classification techniques that help in evaluating strength and weakness of existing gender identification algorithm. Therefore, it helps in developing a novel gender classification algorithm with less computation cost and more accuracy. In this paper, an overview and classification of different gender identification techniques are first presented and it is compared with other existing human identification system by means of their performance.
Handsome wants as handsome does: physical attractiveness and gender differences in revealed sexual preferences.

2011-01-01

In this article I evaluate the effect of physical attractiveness on young adults' sexual and romantic outcomes to reveal gender differences in acted preferences. Using data from the National Longitudinal Study of Adolescent Health (Add Health), a probability sample of young adults (n = 14,276), I investigate gender differences in desired sexual partner accumulation, relationship status, and timing of sexual intercourse. I find gender differences in sexual and romantic strategies consistent with those predicted by the double standard of sexuality and evolutionary theory. Specifically, compared to men, women pursue more committed relationships, fewer sexual partners, and delayed sexual intercourse.

Dissecting the voice: Health professions students' perceptions of instructor age and gender in an online environment and the impact on evaluations for faculty.

PubMed

Doubleday, Alison F; Lee, Lisa M J

2016-11-01

Gender and age bias is well-documented in academia with many studies demonstrating bias in students' evaluations of instructors. Failure of an instructor to meet gender or age-based expectations can translate to lower scores or negative comments on evaluations. While there is some evidence of bias in students' evaluations of online instructors, current studies have not fully examined the relationship between bias and instructor vocal characteristics. First-year dental students at two institutions were randomly assigned one of four videos on spinal cord anatomy to view. Videos contained identical content but were narrated by individuals of different gender and age (younger man, younger woman, older man, older woman). Students completed a content-based prequiz, watched the video, completed a postquiz, and answered a questionnaire evaluating the video and instructor. Students at Institution A rated the younger man and younger woman highest for nearly every evaluation category. At Institution B students rated the older man and younger woman highest. Results reveal that the older woman's voice received the lowest rankings for nearly every question in both samples. This report confirms the presence of gender and age bias in student evaluations of instructors in an online environment and demonstrates that bias may surface in response to vocal characteristics. Bias may impact older women more significantly than other groups. Differences in results from Institution A and Institution B suggest that factors affecting student perceptions of instructors, and the roles that gender and age bias may play in student evaluations, are complex and may be contextual.

2012-01-01

To assess the flexibility of reasoning about gender, children ages 4, 6, and 8 years (N = 72) were interviewed about gender norms when different domains were highlighted. The majority of participants at all ages judged a reversal of gender norms in a different cultural context to be acceptable. They also judged gender norms as a matter of personal choice and they negatively evaluated a rule enforcing gender norms in schools. Older children were more likely to show flexibility than younger children. Justifications obtained from 6- and 8-year-olds showed that they considered adherence to gender norms a matter of personal choice and they viewed the rule enforcing gender norms as unfair. © 2011 The Authors.

This study examined participant gender and gender role differences in estimates of multiple intelligences for self, partner, and various hypothetical, stereotypical, and counter-stereotypical target persons. A general population sample of 261 British participants completed one of four questionnaires that required them to estimate their own and others' multiple intelligences and personality traits. Males estimated their general IQ slightly, but mathematic IQ significantly higher than females, who rated their social and emotional intelligence higher than males. Masculine individuals awarded themselves somewhat higher verbal and practical IQ scores than did female participants. Both participant gender and gender role differences in IQ estimates were found, with gender effects stronger in cognitive and gender role than in "personal" ability estimates. There was a significant effect of gender role on hypothetical persons' intelligence evaluations, with masculine targets receiving significantly higher intelligence estimates compared to feminine targets. More intelligent hypothetical figures were judged as more masculine and less feminine than less intelligent ones.

The policy on gender equality and social inclusion (GESI) in health sector of Nepal is formulated in 2009 targeting toward poor, vulnerable, marginalized social and ethnic groups. Gender inequality and social discrimination are a social problem that affect on individual health finally. The main objective of this paper is to critically analysis and evaluates the Government's strategy on health sector gender equality and social inclusion in Nepal. We collected published and unpublished information assessing the public health, policy analysis and research needs from different sources. A different policy approaches for the analysis and evaluation of GESI strategies is applied in this paper. Universal education, community participation, individual, group and mass communication approaches, and social capital are the key aspects of effective implementation of policy at target levels.
Evaluative ratings and attention across the life span: emotional arousal and gender.

Ferrari, Vera; Bruno, Nicola; Chattat, Rabih; Codispoti, Maurizio

2017-04-01

This study was designed to investigate the evolution of emotional processing over the whole adult life span as a function of stimulus arousal and participants' gender. To this end, self-reported affective evaluation and attentional capture prompted by pleasant and unpleasant pictures varying in arousal were measured in a large sample of participants (n = 211) balanced by gender and equally spread across seven decades from 20 to 90 years. Results showed age differences only for affective evaluation of pleasant stimuli, with opposite patterns depending on stimulus arousal. As age increased, low-arousing pleasant cues (e.g. images of babies) were experienced as more pleasant and arousing by both males and females, whereas high-arousing stimuli (e.g. erotic images) were experienced as less pleasant only by females. In contrast, emotional pictures (both pleasant and unpleasant) were effective at capturing attention in a similar way across participants, regardless of age and gender. Taken together, these findings suggest that specific emotional cues prompt different subjective responses across different age groups, while basic mechanisms involved in attentional engagement towards both pleasant and unpleasant stimuli are preserved in healthy ageing.
Evaluating gender similarities and differences using metasynthesis.

PubMed

Zell, Ethan; Krizan, Zlatan; Teeter, Sabrina R

2015-01-01

Despite the common lay assumption that males and females are profoundly different, Hyde (2005) used data from 46 meta-analyses to demonstrate that males and females are highly similar. Nonetheless, the gender similarities hypothesis has remained controversial. Since Hyde's provocative report, there has been an explosion of meta-analytic interest in psychological gender differences. We utilized this enormous collection of 106 meta-analyses and 386 individual meta-analytic effects to reevaluate the gender similarities hypothesis. Furthermore, we employed a novel data-analytic approach called metasynthesis (Zell & Krizan, 2014) to estimate the average difference between males and females and to explore moderators of gender differences. The average, absolute difference between males and females across domains was relatively small (d = 0.21, SD = 0.14), with the majority of effects being either small (46%) or very small (39%). Magnitude of differences fluctuated somewhat as a function of the psychological domain (e.g., cognitive variables, social and personality variables, well-being), but remained largely constant across age, culture, and generations. These findings provide compelling support for the gender similarities hypothesis, but also underscore conditions under which gender differences are most pronounced.

Background MetaGeM is a wide gender-medicine project comprising post hoc and meta-analyses by gender of clinical outcomes, therapeutic approaches, and safety data from previously conducted observational studies to explore possible gender differences in real-life clinical settings. We report the results of the safety meta-analysis of seven MetaGeM studies, evaluating gender differences in adverse event (AE) incidence and severity. Methods Data were collected between February 2002 and July 2013. Male and female patients were compared for the main safety variables, using Student’s t-test, χ2 test, or Fisher’s exact test as appropriate. As supportive analysis, a logistic regression model was estimated to evaluate associations between gender and outcome. Results In total, 4,870 patients (46% females, 54% males) were included in the analysis; age was higher for females (mean ± standard deviation 61.2±18.3 years) than males (56.3±16.6 years). Overall, 264 AEs were reported (59.1% in males). There were no significant gender differences in the percentage of patients with at least one AE: 3.0% for females versus 3.9% for males, χ2 test P>0.05. According to the logistic regression model results, no association between gender and AEs occurrence seems to exist. A statistically significant gender difference in the percentage of drug-related AEs emerged (37.6% in females vs 20.8% in males, χ2 P=0.0039). Slightly significantly more AEs in females were addressed with treatment compared with males (78.1% vs 66.7%, χ2 P=0.0485). Total serious AEs (SAEs) were 47 (72% in males). The frequency of patients with ≥1 SAE was 0.6% in females versus 1.2% in males (χ2 test P=0.0246). Conclusion This safety analysis on a large sample of almost 5,000 patients with different diseases and treated with a wide range of different drugs provides a useful overview on possible gender differences in drug tolerability, which may be helpful in more accurately designing future clinical trials from a gender-specific perspective.

Gender has been associated with substance use disorders (SUD). However, there are few studies that have evaluated gender differences in a global and a standardized way, and with a large sample of patients with SUD. Our goal is to analyze the role of gender in addiction severity throughout multiple life domains, using the Addiction Severity Index-6 (ASI-6). A naturalistic, multicenter and prospective study was conducted. A total of 221 patients with SUD (80.1% men) were interviewed with the ASI-6. Our results indicate that the Recent Summary Scores (RSSs) of men and women are similar, with the exception of Psychiatric and Partner- Problems, where women showed higher severity (p = .017 and p = .013, respectively). Statistically significant gender differences were found in certain aspects of the ASI-6 domains: men have more problems of physical health, legal issues, and alcohol and other substance use; and woman score higher in problems of mental health, social network, subjective evaluations of SUD consequences, and treatment needs. These results should be taken into account to improve the identification, prevention, and treatment of SUD.

To investigate whether there is a difference in medical student teaching evaluations for male and female clinical physician faculty. The authors examined all teaching evaluations completed by clinical students at one North American medical school in the surgery, obstetrics and gynecology, pediatrics, and internal medicine clinical rotations from 2008 to 2012. The authors focused on how students rated physician faculty on their "overall quality of teaching" using a 5-point response scale (1 = Poor to 5 = Excellent). Linear mixed-effects models provided estimated mean differences in evaluation outcomes by faculty gender. There were 14,107 teaching evaluations of 965 physician faculty. Of these evaluations, 7688 (54%) were for male physician faculty and 6419 (46%) were for female physician faculty. Female physicians received significantly lower mean evaluation scores in all four rotations. The discrepancy was largest in the surgery rotation (males = 4.23, females = 4.01, p = 0.003). Pediatrics showed the next greatest difference (males = 4.44, females = 4.29, p = 0.009), followed by obstetrics and gynecology (males = 4.38, females = 4.26, p = 0.026), and internal medicine (males = 4.35, females = 4.27, p = 0.043). Female physicians received lower teaching evaluations in all four core clinical rotations. This comprehensive examination adds to the medical literature by illuminating subtle differences in evaluations based on physician gender, and provides further evidence of disparities for women in academic medicine.

Ares, Gastón; Gámbaro, Adriana

2007-07-01

The aims of the present study were to study the effect of different carriers and enrichments on the perceived healthiness and willingness to try functional foods; and to evaluate the effect of age, gender and motives underlying food choice. Participants had to evaluate different functional food concepts and had to answer a food choice questionnaire. Results showed that carrier products had the largest effect on consumers' perception of healthiness and willingness to try of the evaluated functional foods concepts. The highest positive relative utilities were achieved when the enrichment was a functional ingredient inherent in the product. Furthermore, gender, age and motives underlying food choice affected the preference patterns for the evaluated functional foods concepts, but it depended on the carrier and enrichment considered, suggesting that functional foods might not be accepted by all the consumers and that they could be tailored for certain groups.

Occupational accidents in professional dance with focus on gender differences

PubMed Central

2013-01-01

Background Classical dance comprises gender specific movement tasks. There is a lack of studies which investigate work related traumatic injuries in terms of gender specific differences in detail. Objective To define gender related differences of occupational accidents. Methods Basis for the evaluation were occupational injuries of professional dancers from three (n = 785; f: n = 358, m: n = 427) state theatres. Results The incidence rate (0.36 per year) was higher in males (m: 0.45, f: 0.29). There were gender specific differences as to the localizations of injuries, particularly the spine region (m: 17.3%, f: 9.8%, p = 0.05) and ankle joint (m: 23.7%, f: 35.5%, p = 0.003). Compared to male dancers, females sustained more injuries resulting from extrinsic factors. Significant differences could specifically be observed with dance floors (m: 8.8%, f: 15.1%, p = 0.02). There were also significant gender differences observed with movement vocabulary. Conclusion The clearly defined gender specific movement activities in classical dance are reflected in occupational accidents sustained. Organisational structures as well as work environment represent a burden likewise to male and female dancers. The presented differences support the development of gender specific injury prevention measures. PMID:24341391

Aims It has been demonstrated that 46– 48% of individuals with bipolar disorder (BD) are at least partially non-adherent with prescribed medication. While some reports note male gender as a predictor of treatment non-adherence in BD, findings have been inconsistent. The construct of gender may also be a matter of cultural orientation, and psychological gender, as a component of self-perception may affect the experience of mental illness. Gender identity is the subjective experience of one’s individuality as male or female. This cross-sectional study evaluated gender and gender identity among men and women with BD as it relates to self-reported medication treatment adherence. Methods This secondary analysis of a larger study on treatment adherence evaluated 70 men and 70 women with bipolar disorder, being treated with mood stabilizing medications in a public mental health setting. Gender identity and adherence were evaluated with the Bem Sex Role Inventory (BSRI) and Tablets Routine Questionnaire (TRQ) respectively. Other measures included BD symptoms with the Hamilton Depression Rating Scale (HAM-D), and Young Mania Rating Scale (YMRS) as well as locus of control with the Multidimensional Health Locus of Control Scale (MHLC) and social support with the Interpersonal Support Evaluation List (ISEL). Results Women with BD had mean scores on the BSRI consistent with general population norms while men with BD had scores suggesting lower levels of self-perceived masculinity than population norms. There were no differences between men and women on adherence, however men with high BSRI masculinity scores had less adherence compared to other men in the sample (p=.04). Lower scores on the “powerful others” dimension of locus of control was associated with lower adherence. For women there was no relationship between BSRI masculinity scores and adherence. Conclusions Gender identity in men with BD differs from general population norms and appears related to adherence. Treatment approaches that are intended to optimize adherence need to consider the construct of gender identity or gender role. PMID:21763217

This study examined two instruments measuring gender dysphoria within the multicenter study of the European Network for the Investigation of Gender Incongruence (ENIGI). The Utrecht Gender Dysphoria Scale (UGDS) and the Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults (GIDYQ-AA) were examined for their definitions of gender dysphoria and their psychometric properties, and evaluated for their congruence in assessing the construct. The sample of 318 participants consisted of 178 male-to-females (MtF) and 140 female-to-males (FtM) who were recruited from the four ENIGI gender clinics. Both instruments were significantly correlated in the group of MtFs. For the FtM group, there was a trend in the same direction but smaller. Gender dysphoria was found to be defined differently in the two instruments, which led to slightly different findings regarding the subgroups. The UGDS detected a difference between the subgroups of early and late onset of gender identity disorder in the group of MtFs, whereas the GIDYQ-AA did not. For the FtM group, no significant effect of age of onset was found. Therefore, both instruments seem to capture not only similar but also different aspects of gender dysphoria. The UGDS focusses on bodily aspects, gender identity, and gender role, while the GIDYQ-AA addresses subjective, somatic, social, and sociolegal aspects. For future research, consistency in theory and definition of gender dysphoria is needed and should be in line with the DSM-5 diagnosis of gender dysphoria in adolescents and adults.
Gambling Outcome Expectancies and Gambling Behavior Among African-American Adolescents: Gender as a Moderating Variable.

Most high school adolescents have reported past year gambling, and males gamble more frequently and problematically than females. Ethnic minority adolescents appear to be gambling at a higher rate than Caucasian adolescents. There is evidence indicating that adolescent gambling outcome expectancies are correlated with gambling behavior, but limited evidence that this relation differs by gender. In the present study gender was evaluated as a moderator in the relation between gambling outcome expectancies and gambling behaviors in an African-American high school sample. Males gambled more frequently, gambled more problematically and held more positive gambling outcome expectancies than females. Gender was found to moderate the relations between gambling frequency and the expectations of material gain, affect, self-evaluation and parental approval. Gender also moderated the relations between gambling problems and expectations of affect and self-evaluation. These findings should inform future adolescent gambling prevention and intervention programs.

Broadband middle ear power reflectance (BMEPR) is an emerging noninvasive electroacoustic measure that evaluates transmission/reflection properties of the middle ear in high resolution. It is applicable over the entire age continuum and is rapid to perform. However, it remains to be determined if BMEPR is just an incremental step in the evolution of middle ear assessment or a major advance in the way middle ear function can be evaluated. To evaluate effects of age, gender, ear, and frequency on BMEPR measurements in adults without a history of middle ear disease and to assess whether these factors require consideration in test development; to review how these data may influence active physiologic process within the inner ear; to consider how they reconcile with previously published results; and to suggest applications for future research. Prospective, cross-sectional, multivariate analysis to evaluate the effects of age, gender, ear, and frequency on BMEPR in humans without a history of middle ear disease and no air-bone gaps exceeding 10 dB for any frequency. Fifty-six adults in two age groups (Group 1: 18-25 yr, n = 28; Group 2: ≥50 and <66 yr, n = 28). Each age group was stratified by ear and gender in a balanced design. Pure tone air conduction and bone-conduction audiometry was conducted in a commercial sound booth, using a clinical audiometer with standard earphones enclosed in supra-aural ear cushions, and a standard bone-conduction oscillator and headband to evaluate for air-bone gaps. Broadband middle ear power reflectance was measured using a calibrated, commercially available computer-controlled system that incorporated a high quality probe assembly to transduce stimuli and record acoustic responses from the ear canal. Data were analyzed with a four-way (2 × 2 × 2 × 16) repeated measures analysis-of-variance (ANOVA) to evaluate the effects of age group (young vs. old), gender (male vs. female), ear (left vs. right), and frequency (258 to 5040 Hz) on BMEPR. The ANOVA revealed a significant main effect of frequency. There were also gender × ear, gender × frequency, and age × gender × ear interactions. The three-way, age × gender × ear interaction captured the essence of results and revealed lowest power reflectance values in younger females and for right ears. This trend partially reversed in the older age group where higher power reflectance values were observed only in right ears of older females. The significant effects of age, gender, ear, and frequency on BMEPR parallel ear- and gender-related differences in hearing sensitivity, ear, and gender differences in the prevalence of spontaneous otoacoustic emissions (OAEs), gender differences in the magnitude of transient evoked OAEs, and ear differences in transient evoked contralateral OAE suppression effects reported in the literature. While original discussions of these aforementioned effects focused primarily on endocochlear and olivocochlear mechanisms, the BMEPR measurements reported herein suggest that middle ear transmission characteristics may also play a role.

Background and aim: Gender medicine takes into account biological and social differences between men and women in terms of prevalence and course of disease, diagnosis and therapy. Medical students should be made aware of this in the early stages of medical education. However, there is hardly any teaching material currently available. This article presents the adaption and first use of the German "Gender Lens," a tool to introduce gender medicine to medical students. Method: The original Canadian "Gender Lens Tool" was translated into German, tested by (n=5) teachers and adapted based on current scientific concepts. The instrument was applied and evaluated using qualitative methods in a student focus group (n=4). It was then piloted in a cohort of fourth-semester students (n=247) in a seminar addressing gender medicine. These experiences were evaluated using quantitative methods. Results: The German translation of the Gender Lens offers students a framework with which to analyze sex and gender differences in terms of the "prevalence, diagnosis, course, therapy and prevention" of a specific disease. Furthermore, it enables a refined search for causes such as "biological disposition, attitudes and behaviors, family and social networks, occupational and material circumstances and experiences with the health care system." Recommendations were received from the student groups regarding teaching methods. Male and female fourth-semester students agreed that the Gender Lens is useful as an introduction to gender medicine. Discussion: Initial experiences with the Gender Lens adapted for the German curriculum suggest that such a learning aid can contribute to raising awareness of gender medicine in medical students.

This study investigated age and gender differences in the quality of attachment to mothers, fathers, and peers, and the association of attachment with measures of self-evaluation in 584 Chinese adolescents in junior high, high school, and university. Their responses to the Inventory of Parent and Peer Attachment indexed attachment quality, and self-evaluation was measured by the Rosenberg Self-Esteem Scale and the Self-Liking and Self-Competence Scale. Consistent with findings with Western samples, our analyses revealed (a) lower parent-child relationship quality in middle (compared to early) adolescence, (b) a significant association of parental and peer attachment with self-evaluation, and (c) gender differences in attachment to peers, with females reporting stronger attachment than males. Chinese females reported stronger maternal attachment than did males, and for females the quality of maternal attachment was more strongly related to self-evaluation than any other attachment relationship. During high school, peer attachment quality - rather than parental - was preeminently associated with self-evaluation. The findings of this study indicate that in a context of considerable consistency of findings with Western studies, parent-child attachment in Chinese adolescents is also influenced by culture-specific practices that influence parent-youth relationships and their meaning to the child.

To evaluate gender effects on the correlation between cortisol, molecular products of lipid peroxidation (LPO) and carbonylation of proteins in patients with heroin addiction. Authors examined 82 patients, 49 men and 33 women, with heroin addiction. Biochemical and statistical methods were used. Gender differences in the carbonylation of proteins were noted. In men, but not in women, the low level of cortisol was associated with an increased content of carbonylated proteins. In women the level of these proteins was lower than in men. Gender did not exert an effect on LPO.

We describe the evaluation of a participatory, garment factory-based intervention to promote gender equity. The intervention comprised four campaigns focused on gender and violence against women, alcoholism, sexual and reproductive health, and HIV/AIDS, which were implemented using information displays (standees and posters) and interactive methods (street play, one-to-one interactions, experience-sharing, and health camps). Each campaign lasted six days and the entire intervention was implemented over 10 months. We evaluated the intervention using a quasi-experimental design in which one factory served as the intervention site and a second as a delayed control. Two mobile-phone-based cross-sectional surveys were conducted at baseline and 12 months with separate systematic random samples of employees from each site. Data on socio-demographic characteristics and knowledge and attitudes related to gender equity, intimate partner violence (IPV) and alcohol use were assessed, and differences in these variables associated with the intervention were examined using difference-in-difference estimation. Analyses of data from 835 respondents revealed substantial, statistically significant improvements in attitudes related to gender equity, unacceptability of IPV, and awareness of IPV and alcohol-related support services. In conclusion, our study offers compelling evidence on the effectiveness of workplace-based interventions in advancing gender equity.

Knowledge of medicinal plants is not only one of the main components in the structure of knowledge in local medical systems but also one of the most studied resources. This study uses a systematic review and meta-analysis of a compilation of ethnobiological studies with a medicinal plant component and the variable of gender to evaluate whether there is a gender-based pattern in medicinal plant knowledge on different scales (national, continental, and global). In this study, three types of meta-analysis are conducted on different scales. We detect no significant differences on the global level; women and men have the same rich knowledge. On the national and continental levels, significant differences are observed in both directions (significant for men and for women), and a lack of significant differences in the knowledge of the genders is also observed. This finding demonstrates that there is no gender-based pattern for knowledge on different scales. PMID:27795730

Gender differences should be considered in vocational high schools so women and men can develop their potentials without being inhibited by gender bias. Gender mainstreaming in vocational high schools is a strategy to integrate gender differences at all stages in teaching-learning process for achieving gender equality and equity. This research evaluates the implementation of gender mainstreaming in vocational high schools consisting of seven key components of gender mainstreaming. Four vocational high schools in Sragen Regency Indonesia have been purposively selected. The data were obtained through in-depth interviews and documentation studies. The data were analyzed using Kabeer’s model of gender analysis. The findings show that not all key components of gender mainstreaming have been implemented in vocational high schools. Most vocational high schools have implemented three of seven key components of gender mainstreaming, namely political will and leadership, policy framework and gender statistics. Meanwhile four of seven key components of gender mainstreaming, namely structure and mechanism, resources, infra structures and civil society have not been well-implemented. In conclusion gender mainstreaming has not been implemented effectively in vocational high schools. Accordingly, the government’s education office should continue to encourage and publish guidelines on the implementation of gender-mainstreaming in vocational high schools.
An evaluation of gender equity in different models of primary care practices in Ontario

2010-01-01

Background The World Health Organization calls for more work evaluating the effect of health care reforms on gender equity in developed countries. We performed this evaluation in Ontario, Canada where primary care models resulting from reforms co-exist. Methods This cross sectional study of primary care practices uses data collected in 2005-2006. Healthcare service models included in the study consist of fee for service (FFS) based, salaried, and capitation based. We compared the quality of care delivered to women and men in practices of each model. We performed multi-level, multivariate regressions adjusting for patient socio-demographic and economic factors to evaluate vertical equity, and adjusting for these and health factors in evaluating horizontal equity. We measured seven dimensions of health service delivery (e.g. accessibility and continuity) and three dimensions of quality of care using patient surveys (n = 5,361) and chart abstractions (n = 4,108). Results Health service delivery measures were comparable in women and men, with differences ≤ 2.2% in all seven dimensions and in all models. Significant gender differences in the health promotion subjects addressed were observed. Female specific preventive manoeuvres were more likely to be performed than other preventive care. Men attending FFS practices were more likely to receive influenza immunization than women (Adjusted odds ratio: 1.75, 95% confidence intervals (CI) 1.05, 2.92). There was no difference in the other three prevention indicators. FFS practices were also more likely to provide recommended care for chronic diseases to men than women (Adjusted difference of -11.2%, CI -21.7, -0.8). A similar trend was observed in Community Health Centers (CHC). Conclusions The observed differences in the type of health promotion subjects discussed are likely an appropriate response to the differential healthcare needs between genders. Chronic disease care is non equitable in FFS but not in capitation based models. We recommend that efforts to monitor and address gender based differences in the delivery of chronic disease management in primary care be pursued. PMID:20331861

2008-02-01

Schizotypy is a multidimensional personality construct that appears to indicate psychosis proneness. Supposedly, schizotypal traits behave differently depending on a person's age and gender, but few studies have examined this relationship. In our study we used the Thinking and Perceptual Style Questionnaire and the Junior Schizotypy Scales. The sample was made up of 321 students (169 males) with an age range of 12 to 17 years. The results show significant differences in gender and age groups. Males score higher than females on Physical Anhedonia, Social Anhedonia, and Impulsive Non-Conformity scales, while females score higher or Positive Symptoms, Negative Evaluation, and Social Paranoia scales. Significant differences were also found among age groups: Unusual experiences, self-referent ideation, social paranoia, thought disorder, and negative evaluation were more frequent in later stages of adolescence. However, the meaning of this difference could be interpreted in terms of emotional turbulence rather than as a direct indicator of vulnerability to psychosis.

Male to female (MtFs) and female to male (FtMs) subjects with gender identity disorder (GID) seem to differ with regard to some sociodemographic and clinical features. Currently, no descriptive studies focusing on MtFs and FtMs attending an Italian clinic are available. To describe the sociodemographic characteristics of a GID population seeking assistance for gender transition and to assess possible differences in those features between MtFs and FtMs. A consecutive series of 198 patients was evaluated for gender dysphoria from July 2008 to May 2011 in four dedicated centers. A total of 140 subjects (mean age 32.6 ± 9.0 years old) meeting the criteria for GID, with their informed consent and without genital reassignment surgery having already been performed, were considered (92 MtFs and 48 FtMs). Diagnosis was based on formal psychiatric classification criteria. Medical history and sociodemographic characteristics were investigated. Subjects were asked to complete the Body Uneasiness Test (a self-rating scale exploring different areas of body-related psychopathology), Symptom Checklist-90 Revised (a self-rating scale to measure psychological state), and the Bem Sex Role Inventory (a self-rating scale to evaluate gender role). The presence of psychiatric comorbidities was evaluated using the Structured Clinical Interviews for Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) (SCID I and SCID II). Several significant differences were found between MtFs and FtMs regarding lifestyle and sociodemographic factors and in psychometric test scores.

Cohabitation has become the modal path to marriage in the United States. However, little is known about what cohabitation means to young adults today. Drawing on data from 18 focus groups (N=138) and 54 in-depth interviews with young adults, this exploratory study investigates motivations to cohabit, and examines potential gender differences in those motivations and the meanings attached to them. We find that primary motives to cohabit include spending time together, sharing expenses, and evaluating compatibility. Strong gender differences emerge in how respondents discuss these themes and how they characterize the drawbacks of cohabitation, with men more concerned about loss of freedom and women with delays in marriage. Overall, our findings suggest that gendered cultural norms governing intimate relationships extend to cohabiting unions, and point to gender differences in the perceived role of cohabitation in union formation processes.

How female and male physicians' communication is perceived differently.

Mast, Marianne Schmid; Kadji, Keou Kambiwa

This paper is based on a 2017 Baltimore International Conference on Communication in Healthcare (ICCH) plenary presentation by the first author and addresses how female and male physicians' communication is perceived and evaluated differently. Female physicians use patient-centered communication which is the interaction style clearly preferred by patients. Logically, patients should be much more satisfied with female than male physicians. However, research shows that this is not the case. This article provides an overview on how female and male physician communication is evaluated and perceived differently by patients and discusses whether and how gender stereotypes can explain these differences in perception and evaluation. Male physicians obtain good patient outcomes when verbally expressing patient-centeredness while female physicians have patients who report better outcomes when they adapt their nonverbal communication to the different needs of their patients. The analysis reveals that existing empirical findings cannot simply be explained by the adherence or not to gender stereotypes. Female physicians do not always get credit for showing gender role congruent behavior. All in all, female and male physicians do not obtain credit for the same behaviors. Physician communication training might put different accents for female and male physicians. Copyright © 2018 Elsevier B.V. All rights reserved.
Gender differences in highway driving performance after administration of sleep medication: a review of the literature.

Verster, Joris C; Roth, Thomas

2012-01-01

It is generally assumed that there are minimal gender differences in the safety and efficacy of central nervous system drugs, as is evidenced by men and women receiving the same drug dosage. There is, however, evidence that drugs may have a differential effect on performance in men and women, given reported differences in pharmacokinetics as well as the presence or absence and severity of adverse effects. It is especially important to verify whether gender differences in performance exist in case of activities that have potentially dangerous outcomes such as driving a car. This review summarizes the current scientific evidence on gender differences in driving performance after treatment with hypnotic drugs. A literature search was conducted to obtain all studies that conducted on-road driving tests to examine the effects hypnotic drugs on driving. Cross-references were checked and technical reports and raw data were obtained, if possible. Fourteen studies were evaluated. Many studies did not allow analyses of gender effects because only women were included. Others did not report data on gender analyses. Technical reports and additional data analyses revealed significant gender differences in driving performance the morning following bedtime administration of flurazepam (30 mg) and after middle-of-the-night administration of zolpidem (10 mg). No significant gender differences were found for ramelteon (8 mg), lormetazepam (1 and 2 mg), zaleplon (10 and 20 mg), and zopiclone (7.5 mg). Although the available data are limited, the results show that significant gender differences have been found for some drugs but not others. Therefore, in the future more research is needed to reveal potential gender differences and to determine what mediates them.

2014-01-01

The aim of this study was to investigate the biological effects of sex hormones (17β-estradiol and testosterone) on rabbit articular chondrocytes from different genders. We cultured primary rabbit articular chondrocytes from both genders with varying concentration of sex hormones. We evaluate cell proliferation and biochemical functions by MTT and GAG assay. The chondrocyte function and phenotypes were analyzed by mRNA level using RT-PCR. Immunocytochemical staining was also used to evaluate the generation of collagen-II. This study demonstrated that 17β-estradiol had greater positive regulation on the biological function and gene expressions of articular chondrocytes than testosterone, with the optimal concentrations of 10(-6) and 10(-7) M, particularly for female chondrocytes.
Gender monitoring and gender reassignment of children and adolescents with a somatic disorder of sex development.

Meyer-Bahlburg, Heino F L

2011-10-01

Individuals born with a somatic disorder of sex development (DSD) have high rates of gender-atypical behavior, gender uncertainty, gender dysphoria, and patient-initiated gender change in childhood, adolescence,and adulthood. This article addresses the issues a mental health services provider has to consider in evaluating and assisting such patients and provides examples of assessment-method batteries. To date, the World Professional Association for Transgender Health's Standards of Care, 6th version, for non-DSD patients with gender dysphoria, may be cautiously used for guidance, taking into account the considerable differences in presentation and medical context between gender dysphoric patients with and without a DSD.
Preferences for Pink and Blue: The Development of Color Preferences as a Distinct Gender-Typed Behavior in Toddlers.

PubMed

Wong, Wang I; Hines, Melissa

2015-07-01

Many gender differences are thought to result from interactions between inborn factors and sociocognitive processes that occur after birth. There is controversy, however, over the causes of gender-typed preferences for the colors pink and blue, with some viewing these preferences as arising solely from sociocognitive processes of gender development. We evaluated preferences for gender-typed colors, and compared them to gender-typed toy and activity preferences in 126 toddlers on two occasions separated by 6-8 months (at Time 1, M = 29 months; range 20-40). Color preferences were assessed using color cards and neutral toys in gender-typed colors. Gender-typed toy and activity preferences were assessed using a parent-report questionnaire, the Preschool Activities Inventory. Color preferences were also assessed for the toddlers' parents using color cards. A gender difference in color preferences was present between 2 and 3 years of age and strengthened near the third birthday, at which time it was large (d > 1). In contrast to their parents, toddlers' gender-typed color preferences were stronger and unstable. Gender-typed color preferences also appeared to establish later and were less stable than gender-typed toy and activity preferences. Gender-typed color preferences were largely uncorrelated with gender-typed toy and activity preferences. These results suggest that the factors influencing gender-typed color preferences and gender-typed toy and activity preferences differ in some respects. Our findings suggest that sociocognitive influences and play with gender-typed toys that happen to be made in gender-typed colors contribute to toddlers' gender-typed color preferences.
Female Surgeons as Counter Stereotype: The Impact of Gender Perceptions on Trainee Evaluations of Physician Faculty.

Fassiotto, Magali; Li, Jie; Maldonado, Yvonne; Kothary, Nishita

2018-02-02

Similar to women in Science, Technology, Engineering and Mathematics disciplines, women in medicine are subject to negative stereotyping when they do not adhere to their sex-role expectations. These biases may vary by specialty, largely dependent on the gender's representation in that specialty. Thus, females in male-dominated surgical specialties are especially at risk of stereotype threat. Herein, we present the role of gender expectations using trainee evaluations of physician faculty at a single academic center, over a 5-year period (2010-2014). Using Graduate Medical Education evaluation data of physician faculty from MedHub, we examined the differences in evaluation scores for male and female physicians within specialties that have traditionally had low female representation (e.g., surgical fields) compared to those with average or high female representation (e.g., pediatrics). Stanford Medicine residents and fellows' MedHub ratings of their physician faculty from 2010 to 2014. A total of 3648 evaluations across 1066 physician faculty. Overall, female physicians received lower median scores than their male counterparts across all specialties. When using regression analyses controlling for race, age, rank, and specialty-specific characteristics, the negative effect persists only for female physicians in specialties with low female representation. This finding suggests that female physicians in traditionally male-dominated specialties may face different criteria based on sex-role expectations when being evaluated by trainees. As trainee evaluations play an important role in career advancement decisions, dictate perceptions of quality within academic medical centers and affect overall job satisfaction, we propose that these differences in evaluations based merely on gender stereotypes could account, in part, for the narrowing pipeline of women promoted to higher ranks in academic medicine.

This paper investigates potential gender and age differences in conviction and crash occurrence subsequent to being directed to attend Iowa's Driver Improvement Program (DIP). Binary logit models were developed to investigate the factors that influence conviction occurrence after DIP by gender and age. Because of the low crash occurrence subsequent to DIP, association rules were applied to investigate the factors that influence crash occurrence subsequent to DIP, in lieu of econometric models. There were statistical significant differences by driver gender, age, and conviction history in the likelihood of subsequent convictions. However, this paper found no association between DIP outcome, crash history, and crash occurrence. Evaluating the differences in conviction and crash occurrence subsequent to DIP between female and male drivers, and among different age groups can lead to improvements of the effectiveness of DIPs and help to identify low-cost intervention measures, customized based on drivers' gender and age, for improving driving behaviors.

Sczesny, Sabine; Gumí, Tània; Guimerà, Roger; Sales-Pardo, Marta

2017-01-01

Leadership positions are still stereotyped as masculine, especially in male-dominated fields (e.g., engineering). So how do gender stereotypes affect the evaluation of leaders and team cohesiveness in the process of team development? In our study participants worked in 45 small teams (4–5 members). Each team was headed by either a female or male leader, so that 45 leaders (33% women) supervised 258 team members (39% women). Over a period of nine months, the teams developed specific engineering projects as part of their professional undergraduate training. We examined leaders’ self-evaluation, their evaluation by team members, and team cohesiveness at two points of time (month three and month nine, the final month of the collaboration). While we did not find any gender differences in leaders’ self-evaluation at the beginning, female leaders evaluated themselves more favorably than men at the end of the projects. Moreover, female leaders were evaluated more favorably than male leaders at the beginning of the project, but the evaluation by team members did not differ at the end of the projects. Finally, we found a tendency for female leaders to build more cohesive teams than male leaders. PMID:29059231
Gender differences in performance of script analysis by older adults.

Script analysis as a test of executive functions is presumed sensitive to cognitive changes seen with increasing age. Two studies evaluated if gender differences exist in performance on scripts for familiar and unfamiliar tasks in groups of cognitively intact older adults. In Study 1, 26 older adults completed male and female stereotypical scripts. Results were not significant but a tendency was present, with genders making fewer impossible errors on the gender-typical script. Such an interaction was also noted in Study 2, which contrasted 50 older with 50 younger adults on three scripts, including a script with neutral familiarity. The pattern of significant interactions for errors suggested the need to use scripts that are based upon tasks that are equally familiar to both genders.

Adolescents in foster care are at high risk for cigarette smoking. However, it is not clear how their smoking behaviors vary by gender. The present study examined lifetime and current smoking among males and females, and explored gender-specific risk factors for engagement in smoking behaviors. Data from the Multi Site Evaluation of Foster Youth Programs was used to evaluate patterns of smoking among adolescents aged 12-18 years (N = 1121; 489 males, 632 females). Males and females did not differ significantly in rates of lifetime and current smoking, or in the age of smoking initiation and number of cigarettes smoked on a typical day. Gender-based analyses revealed that older age and placement in group homes or residential treatment facilities were associated with heightened risk of smoking among males. In contrast, sexual minority status (i.e., nonheterosexual orientation) and increased childhood victimization were associated with heightened risk of smoking among females. A history of running away was linked to smoking in both genders. Gender should be considered when designing intervention programs to address cigarette smoking among foster youth, as the stressors associated with smoking may differ for males and females.

Osteogenesis imperfecta (OI) is a dominant skeletal disorder characterized by bone fragility and deformities. Though the oim mouse model has been the most widely studied of the OI models, it has only recently been suggested to exhibit gender-dependent differences in bone mineralization. To characterize the impact of gender on the morphometry/ultra-structure, mechanical properties, and biochemical composition of oim bone on the congenic C57BL/J6 background, 4-month-old oim/oim, +/oim, and wild-type (wt) female and male tibiae were evaluated using micro-computed tomography, three-point bending, and Raman spectroscopy. Dramatic gender differences were evident in both cortical and trabecular bone morphological and geometric parameters. Male mice had inherently more bone and increased moment of inertia than genotype-matched female counterparts with corresponding increases in bone biomechanical strength. The primary influence of gender was structure/geometry in bone growth and mechanical properties, whereas the mineral/matrix composition and hydroxyproline content of bone were influenced primarily by the oim collagen mutation. This study provides evidence of the importance of gender in the evaluation and interpretation of potential therapeutic strategies when using mouse models of OI.

To systematically review experimental evidence for interventions mitigating gender bias in employment. Unconscious endorsement of gender stereotypes can undermine academic medicine's commitment to gender equity. The authors performed electronic and hand searches for randomized controlled studies since 1973 of interventions that affect gender differences in evaluation of job applicants. Twenty-seven studies met all inclusion criteria. Interventions fell into three categories: application information, applicant features, and rating conditions. The studies identified gender bias as the difference in ratings or perceptions of men and women with identical qualifications. Studies reaffirmed negative bias against women being evaluated for positions traditionally or predominantly held by men (male sex-typed jobs). The assessments of male and female raters rarely differed. Interventions that provided raters with clear evidence of job-relevant competencies were effective. However, clearly competent women were rated lower than equivalent men for male sex-typed jobs unless evidence of communal qualities was also provided. A commitment to the value of credentials before review of applicants and women's presence at above 25% of the applicant pool eliminated bias against women. Two studies found unconscious resistance to "antibias" training, which could be overcome with distraction or an intervening task. Explicit employment equity policies and an attractive appearance benefited men more than women, whereas repeated employment gaps were more detrimental to men. Masculine-scented perfume favored the hiring of both sexes. Negative bias occurred against women who expressed anger or who were perceived as self-promoting. High-level evidence exists for strategies to mitigate gender bias in hiring.
The relationship of gender and gender identity to treatment adherence among individuals with bipolar disorder.

It has been demonstrated that 46% to 48% of individuals with bipolar disorder (BD) are at least partially nonadherent with prescribed medication. Reports of whether male gender is a predictor of treatment nonadherence in BD have been inconsistent. The construct of gender may also be a matter of cultural orientation, and psychological gender, as a component of self-perception, may affect the experience of mental illness. Gender identity is the subjective experience of one's individuality as male or female. This cross-sectional study evaluated gender and gender identity among men and women with BD as they relate to self-reported medication treatment adherence. This secondary analysis of a larger study on treatment adherence evaluated men and women with BD being treated with mood-stabilizing medications in a community mental health clinic. Gender identity and treatment adherence were evaluated using the Bem Sex Role Inventory (BSRI) and the Tablets Routine Questionnaire, respectively. Other measures included assessing BD symptoms using the Hamilton Depression Rating Scale and mania symptoms using the Young Mania Rating Scale, as well as psychosocial support with the Interpersonal Support Evaluation List and locus of control with the Multidimensional Health Locus of Control Scale. Mean age of the 70 men and 70 women with type I BD was 43.1 years for adherent patients and 40.8 years for nonadherent patients. Women with BD had mean scores on the BSRI consistent with general population norms, whereas men with BD had scores suggesting lower levels of self-perceived masculinity than population norms. There were no differences between men and women on adherence; however, men with high BSRI masculinity scores had less adherence than other men in the sample (P = 0.04). Lower scores on the "powerful others" dimension of locus of control were associated with lower adherence. For women, there was no relationship between BSRI masculinity scores and adherence. Gender identity in men with BD differed from general population norms and appeared to be related to adherence. Treatment approaches that are intended to optimize adherence need to consider the construct of gender identity or gender role. ClinicalTrials.gov ID: NCT00183495.

The incidence of bladder cancer is three to four times greater in men than in women. However, women are diagnosed with more advanced disease at presentation and have less favorable outcomes after treatment. To review the literature on potential biologic mechanisms underlying differential gender risk for bladder cancer, and evidence regarding gender disparities in bladder cancer presentation, management, and outcomes. A literature search of English-language publications that included an analysis of the association of gender with bladder cancer was performed using Pubmed. Ninety-seven articles were selected for analysis with the consensus of all authors. It has been shown that the gender difference in bladder cancer incidence is independent of differences in exposure risk, including smoking status. Potential molecular mechanisms include disparate metabolism of carcinogens by hepatic enzymes between men and women, resulting in differential exposure of the urothelium to carcinogens. In addition, the activity of the sex steroid hormone pathway may play a role in bladder cancer development, with demonstration that both androgens and estrogens have biologic effects in bladder cancer in vitro and in vivo. Importantly, gender differences exist in the timeliness and completeness of hematuria evaluation, with women experiencing a significantly greater delay in urologic referral and undergoing guideline-concordant imaging less frequently. Correspondingly, women have more advanced tumors at the time of bladder cancer diagnosis. Interestingly, higher cancer-specific mortality has been noted among women even after adjusting for tumor stage and treatment modality. Numerous potential biologic and epidemiologic factors probably underlie the gender differences observed for bladder cancer incidence, stage at diagnosis, and outcomes. Continued evaluation to define clinical applications for manipulation of the sex steroid pathway and to improve the standardization of hematuria evaluation in women may improve future patient outcomes and reduce these disparities. We describe the scientific basis and clinical evidence to explain the greater incidence of bladder cancer in men and the adverse presentation and outcomes for this disease in women. We identify goals for improving patient survival and reducing gender disparities in bladder cancer. Copyright © 2015 European Association of Urology. Published by Elsevier B.V. All rights reserved.
Negotiating gender roles: gender differences in assertive negotiating are mediated by women's fear of backlash and attenuated when negotiating on behalf of others.

PubMed

Amanatullah, Emily T; Morris, Michael W

2010-02-01

The authors propose that gender differences in negotiations reflect women's contextually contingent impression management strategies. They argue that the same behavior, bargaining assertively, is construed as congruent with female gender roles in some contexts yet incongruent in other contexts. Further, women take this contextual variation into account, adjusting their bargaining behavior to manage social impressions. A particularly important contextual variable is advocacy-whether bargaining on one's own behalf versus on another's behalf. In self-advocacy contexts, women anticipate that assertiveness will evoke incongruity evaluations, negative attributions, and subsequent "backlash"; hence, women hedge their assertiveness, using fewer competing tactics and obtaining lower outcomes. However, in other-advocacy contexts, women achieve better outcomes as they do not expect incongruity evaluations or engage in hedging. In a controlled laboratory experiment, the authors found that gender interacts with advocacy context in this way to determine negotiation style and outcomes. Additionally, process measures of anticipated attributions and backlash statistically mediated this interaction effect. Copyright 2009 APA, all rights reserved

Since 1995, women have comprised more than 40% of all medical school graduates. However, representation at leadership levels in medicine remains considerably lower. Gender representation among the American Board of Medical Specialties (ABMS) boards of directors (BODs) has not previously been evaluated. Our objective was to determine the relative representation of women on ABMS BODs and compare it with the in-training and in-practice gender composition of the respective specialties. The composition of the ABMS BODs was obtained from websites in March 2016 for all Member Boards. Association of American Medical Colleges and American Medical Association data were utilized to identify current and future trends in gender composition. Although represented by a common board, neurology and psychiatry were evaluated separately because of their very different practices and gender demographic characteristics. A total of 25 specialties were evaluated. Of the 25 specialties analyzed, 12 BODs have proportional gender representation compared with their constituency. Seven specialties have a larger proportion of women serving on their boards compared with physicians in practice, and 6 specialties have a greater proportion of men populating their BODs. Based on the most recent trainee data (2013), women have increasing workforce representation in almost all specialties. Although women in both training and practice are approaching equal representation, there is variability in gender ratios across specialties. Directorship within ABMS BODs has a more equitable gender distribution than other areas of leadership in medicine. Further investigation is needed to determine the reasons behind this difference and to identify opportunities to engage women in leadership in medicine.

Interoception and gender: What aspects should we pay attention to?

Grabauskaitė, Aida; Baranauskas, Mindaugas; Griškova-Bulanova, Inga

2017-02-01

Interoception is involved in both somatic and mental disorders with different prevalence between genders; however, gender differences are often neglected. To examine the potential gender differences in interoceptive awareness, we recruited 376 healthy subjects (51% males, aged 17-30years), to fill in the Multidimensional Assessment of Interoceptive Awareness (MAIA). Of that sample, in a subgroup of 40 subjects (50% males), interoceptive accuracy was assessed by heartbeat counting task (HCT). The results on interroceptive awareness suggest that females tendto notice bodily sensations more often, better understand relations between bodily sensations and emotional states, worry or experience more emotional distress with sensations of pain or discomfort and see body as less safe. The results of interoceptive accuracy further suggest that females are less efficient in consciously detecting heartbeats. Therefore, gender should be considered when interoceptive evaluation is performed in disorders associated to bodily sensations and to the emotional/mood states. Copyright © 2016 Elsevier Inc.

2011-01-01

Body checking includes any behavior aimed at global or specific evaluations of appearance characteristics. Men and women are believed to express these behaviors differently, possibly reflecting different socialization. However, there has been no empirical test of the impact of gender on body checking. A total of 1024 male and female college students completed two measures of body checking, the Body Checking Questionnaire and the Male Body Checking Questionnaire. Using multiple group confirmatory factor analysis, differential item functioning (DIF) was explored in a composite of these measures. Two global latent factors were identified (female and male body checking severity), and there were expected gender differences in these factors even after controlling for DIF. Ten items were found to be unbiased by gender and provide a suitable brief measure of body checking for mixed gender research. Practical applications for body checking assessment and theoretical implications are discussed. Copyright © 2010 Elsevier Ltd. All rights reserved.

In this cross-sectional study, the qualitative and quantitative throwing performance of male and female athletes (6 to 16 years of age) was analyzed. The goal of this study was to assess whether there were gender based qualitative and quantitative differences in throwing performance of young athletes, throughout three different age bands (childhood, pubescence, and adolescence). Furthermore, we explored whether all components of the throwing movement are equally affected by gender differences. Focus was placed on five essential components of action: trunk, forearm, humerus, stepping, and backswing. Therefore, children and adolescents (N = 96) were invited to throw three times from three different distances, while aiming at a target placed at shoulder height. The participants were aspiring athletes, competitive in the sport handball. For analyzing the quality of movement the component approach of Halverson and Roberton (1984) was used. The throwing accuracy was noted and used to evaluate the quantitative performance of the throwing movement. Throughout three different age bands, no statistically significant difference was found between genders in throwing accuracy, i.e., quantitative performance. Regarding the qualitative evaluation of the throwing movement, male and female athletes differed significantly. The component approach yielded higher scores for male than for female participants. As expected, with increasing age qualitative and quantitative performance of male and female athletes improved. These results suggest that there are gender-specific differences in qualitative throwing performance, but not necessarily in quantitative throwing performance. Exploration shows that differences in the qualitative throwing performance were seen in specific components of action. Male and female athletes demonstrated similar movement patterns in humerus and forearm actions, but differed in trunk, stepping, and backswing actions. PMID:28261142

To determine if there are age or gender-related differences in reporting fear as a symptom of epileptic seizure, all clinical charts of patients evaluated at the "C. Munari - Epilepsy Surgery Center" of Milan from 1990 to June 2005 were analyzed, looking for patients with ictal fear. Among the 2,530 clinical charts examined (1,330 male and 1,200 female), 265 patients were found with ictal fear (100 men, 165 women). The gender difference in reporting ictal fear was not so marked in the pediatric age group (98 girls, 74 boys), whereas in adult patients the difference was significant (158 women, 83 men). Interestingly, more men than women (14:3) had ictal fear during childhood that disappeared during adulthood. The literature review confirmed that ictal fear is significantly more common in women, though there is no gender difference in the pediatric age group.

Participants included male and female adults entering restrooms at two public shopping…
Individual differences in melancholy gender among women: does ambivalence matter?

PubMed

Jay, Meg

2007-01-01

This research offers an empirical investigation inspired by Butler's theory of melancholy gender (1995) and a revision of this theory (Jay 2007a). Psychoanalytic feminist theory is drawn on to suggest that melancholy and gender are more likely to be associated in female development than in male development, and Freud's theory of melancholy (1917) is taken to suggest that ambivalence predicts individual differences in melancholy gender among women. In a longitudinal study of women's adult development, an examination of femininity, depressive symptoms, and ambivalence in attachment was conducted in order to evaluate these claims. Findings show that depressive symptoms and femininity are significantly correlated within the sample, but that individual differences in melancholy gender exist. To understand these differences, an analysis was conducted to determine whether ambivalence in attachment accounts for the relation between depressive symptoms and femininity; complementary analyses examined whether low ambivalence in attachment attenuates, or lessens, the relation between femininity and depressive symptoms. Results from these analyses support the notion that it is not the loss and internalization of the same-sex object choice per se that results in melancholy gender in women, as Butler argues; rather, it is the internalization of a lost, ambivalent same-sex attachment that forges the link between melancholy and gender. Narrative material is presented to personify melancholy and unmelancholy gender.

Despite a high prevalence of coronary heart disease in both genders, studies show a gender disparity in evaluation whereby women are less likely than men to undergo timely or comprehensive cardiac investigation. Using videographic analysis, we sought to quantify gender differences in provider recommendations and patient evaluations. We analyzed video recordings from our Chest Pain Choice trial, a single center patient-level randomized trial in which emergency department patients with chest pain being considered for cardiac stress testing were randomized to shared decision-making or usual care. Patient-provider interactions were video recorded. We compared characteristics and outcomes by gender. Of the 204 patients enrolled (101 decision aid; 103 usual care), 120 (58.8%) were female. Of the 75 providers evaluated, 20 (26.7%) were female. The mean (SD) pretest probability of acute coronary syndrome was lower in women [3.7% (2.2) vs 6.7% (4.4), P=.0002]. There was no gender effect on duration of discussion, clinician recommendations, OPTION scores, patient perceptions, or eventual patient dispositions. When the clinician and patient gender matched, OPTION scores were lower (interaction P=.002), and patients were less likely to find the information to be very helpful (interaction P=.10). Despite a lower pretest probability of acute coronary syndrome in women, we did not observe any significant gender disparity in how patients were managed and evaluated. When the patients' and providers' gender matched, the provider involved them less in the decision making process, and the information provided was less helpful than when the genders did not match.

Some contend that gender differences in outcomes after lower extremity bypass (LEB) for peripheral arterial disease (PAD) relate to socioeconomic factors (SEFs). Here, we evaluate these disparities with attention to clinically relevant yet understudied SEF. A retrospective cohort study of patients aged >50 y with PAD undergoing LEB was performed using data from Pennsylvania Health care and Cost Containment Council (2003-2011). Multivariable logistic regression modeling was performed to evaluate the association between gender and outcomes with adjustment for potential confounders including SEF such as income, insurance provider, distance to hospital, and race. Generalized estimating equations were used to adjust for hospital clustering. Independent models were developed to examine death or serious morbidity (DSM) and failure-to-rescue (FTR). Of 4202 patients identified, 1510 (36%) were women. SEF differed by gender. DSM was more frequent in women (15.6% versus 12.2%; P = 0.002). There was no association between gender and FTR in univariate analysis (P = 0.49). SEFs were associated with DSM and FTR. After adjustment for potential confounders including SEF, women remained more likely to experience DSM (odds ratio = 1.28; P = 0.01). There remained no significant association between gender and FTR on independent modeling (odds ratio = 0.49; P = 0.11). Women undergoing LEB in the state of Pennsylvania are at increased risk of poor outcomes, which is not completely explained by SEF. Quality of postoperative care does not appear to be different between gender as there was no difference in FTR. To improve these outcomes, efforts should be made to increase awareness of PAD and promote screening among high-risk women to ensure timely diagnosis and referral. Copyright © 2014 Elsevier Inc.

Differences between women and men in education, employment, political and economic empowerment have been well-documented in China due to the long traditional culture that male is superior to female. This study is to explore whether the similar gender differences exist in the use of health care by analyzing hospital admission, duration of hospitalization and medical expense of both genders in a Chinese hospital. This cross-sectional study evaluated the gender differences in clinical and epidemiologic characteristics of patients who were admitted for any reason to hospital in Zhuhai Special Economic Zone, Southern China, from January 1, 2003, through December 31, 2009. Chi-square test was used to calculate differences between proportions and the t test was used to test differences between means. A total of 156,887 patients were recruited in the analysis, with a male/female ratio of 1.1:1.0. The average age and the duration of hospitalization were significantly greater among men (p < 0.05). A larger proportion of hospitalized female underwent surgery compared to male (p < 0.05). The total medical expense per inpatient indicated important differences between genders, with higher expenditures observed among men (p < 0.05). Furthermore, gender differences were observed in length of hospitalization and medical expense for five common conditions respectively and most differences favoring men were significant (p < 0.05) while differences favoring women were not significant (p > 0.05). Among all the self-paid patients, men were also superior in all investigating variables compared with women. Gender differences in the use of health care do occur in China. Despite of demographic factors, the differences between female and male can be in part explained by social power relations. China should increase attention to gender and equity in health.

Evaluation of the position of mental foramen aids in forensic, surgical, endodontic, as well as diagnostic procedures. Thus, in view of this, the present study was conducted among the population of Pune, a central part of India, to determine the most regular location of the mental foramen and to estimate difference in position of mental foramen based on gender. The present retrospective study was commenced on 200 digital panoramic radiographs of dentate patients. The location of the representation of the mental foramen was traced. Measurements for evaluating distance of superior and inferior borders of the foramen in relation to the lower border of the mandible were made using the reference lines drawn from anatomical landmarks. The data so obtained were statistically analyzed using chi-square test. The most common position of mental foramen among Pune population in horizontal plane in both male and female patients was in line with second premolar followed by position in between first and second premolar, whereas in the vertical plane, most common position was at or in line with apex of second premolar followed by in between apex of first and second premolar. The variation in length of superior and inferior border of the foramen in relation to lower border of the mandible with respect to gender was found to be significant, with p-value <0.05. There was no difference in position of mental foramen in horizontal and vertical planes based on gender. The stability of location of mental foramen and significant difference in length of superior and inferior border of the foramen in relation to lower border of the mandible with respect to gender offer its application in forensic identification of gender.
Gender differences in moral judgment and the evaluation of gender-specified moral agents.

Capraro, Valerio; Sippel, Jonathan

Whether, and if so, how exactly gender differences are manifested in moral judgment has recently been at the center of much research on moral decision making. Previous research suggests that women are more deontological than men in personal, but not impersonal, moral dilemmas. However, typical personal and impersonal moral dilemmas differ along two dimensions: Personal dilemmas are more emotionally salient than impersonal ones and involve a violation of Kant's practical imperative that humans must never be used as a mere means, but only as ends. Thus, it remains unclear whether the reported gender difference is due to emotional salience or to the violation of the practical imperative. To answer this question, we explore gender differences in three moral dilemmas: a typical personal dilemma, a typical impersonal dilemma, and an intermediate dilemma, which is not as emotionally salient as typical personal moral dilemmas, but contains an equally strong violation of Kant's practical imperative. While we replicate the result that women tend to embrace deontological ethics more than men in personal, but not impersonal, dilemmas, we find no gender differences in the intermediate situation. This suggests that gender differences in these type of dilemmas are driven by emotional salience, and not by the violation of the practical imperative. Additionally, we also explore whether people think that women should behave differently than men in these dilemmas. Across all three dilemmas, we find no statistically significant differences about how people think men and women should behave.

Women continue to be under-represented in the sciences, with their representation declining at each progressive academic level. These differences persist despite long-running policies to ameliorate gender inequity. We compared gender differences in exposure and visibility at an evolutionary biology conference for attendees at two different academic levels: student and post-PhD academic. Despite there being almost exactly a 1:1 ratio of women and men attending the conference, we found that when considering only those who presented talks, women spoke for far less time than men of an equivalent academic level: on average student women presented for 23% less time than student men, and academic women presented for 17% less time than academic men. We conducted more detailed analyses to tease apart whether this gender difference was caused by decisions made by the attendees or through bias in evaluation of the abstracts. At both academic levels, women and men were equally likely to request a presentation. However, women were more likely than men to prefer a short talk, regardless of academic level. We discuss potential underlying reasons for this gender bias, and provide recommendations to avoid similar gender biases at future conferences. PMID:25346879

This study aimed to investigate gender differences in the relationship between fat-free mass index (FFMI) and fat mass index (FMI) by applying body composition chart on Korean elementary students. Data from 965 healthy Korean children of 8 to 12 years of age (501 boys, 464 girls) were obtained. FFMI and FMI were plotted on the body composition chart, and the differences in the relationships between FFMI and FMI were separately evaluated by gender or grade. Weight was heavier and BMI was higher in 3rd and 4th grade boys compare to girls. The value of FFM was higher in boys, but FM was not different. In subgroup analysis by grade, significant gender by FFMI interaction (p=0.015) was found, indicating that the slope of the lines for FMI vs. FFMI was different between boys and girls (Figure was not shown). In subgroup analysis by gender, grade by FFMI interaction was significant in boys, indicating that FMI vs. FFMI relationship differed according to grade only in boys. Boys are leaner than girls, despite having similar BMI. Gender difference in the direction of the change of the FFMI and FMI relationship is evident in children.
The political economy of urban homicide: assessing the relative impact of gender inequality on sex-specific victimization.

This research examines the ways in which the changing political economy of urban areas has contributed differently to the homicide victimization rates of females and males across US cities. Recent research, while relatively limited, has presented disparate results regarding the effect of gender inequality on urban sex-specific victimization. Our work further explores this relationship by taking into account relative gender disparities in income, education, labor market opportunities, and politics in an examination of sex-specific homicide victimization in 1990. Key to this current investigation is the evaluation of feminist and lifestyle arguments that suggest that structural gender inequality has a unique effect on female victimization. Overall, our findings reveal gender inequality to be a significant predictor of both male and female urban homicide. While these findings suggest mixed support for theoretical arguments regarding gender inequality, further analyses reveal significant differences in specific types of gender inequality on victimization patterns across genders. These additional results highlight the need for greater attention toward both methodological and theoretical issues when examining the interconnections between gender, political economy, and violence in research.
Motivation in educational contexts: does gender matter?

PubMed

Butler, Ruth

2014-01-01

Girls and women now outperform boys and men on many indices of academic achievement. Gender differences in motivation may underlie these trends. In this chapter, I review and integrate research on gender differences in self-evaluation, self-regulation, and achievement goals. I argue for the existence of gendered tendencies "to prove" versus "to try and to improve," whereby males tend to orient to demonstrating and defending their abilities, and females to working hard and addressing deficiencies. I discuss how these motivations develop within social and educational contexts of learning, and intersect with gendered patterns of socialization, values, and behaviors in other arenas, especially relational ones. Recurring themes include the costs and benefits of differential emphases on competition and self-promotion versus affiliation and consideration of others in the family, peer group, and classroom. I conclude with some recommendations for creating classroom environments that might promote optimal motivation among all students, regardless of gender.

anthropometry facilitates the evaluation of the risks associated with reduced lean body mass, as well as of excess adiposity. However, very little is known regarding the anthropometric standards among the elderly and the differences observed between the genders and among the various age groups Objective: to compare indicators and indices anthropometrics of the elderly by gender and age group. a cross-sectional study was undertaken using a representative probability sample, involving 621 elderly. We evaluated the weight, height, circumferences (waist, hip, calf and arm); body mass index, body adiposity index, waist-hip ratio and waist-stature ratio. women were found to have a higher mean body mass index, waist-stature ratio, body adiposity index and arm circumference (p < 0.001), whereas men had higher values for weight, height and waist-hip ratio (p < 0.001). The average arm and calf circumference, however, did not differ between the genders (p > 0.05). Weight, and calf and arm circumferences were observed to be lower in the older age groups (p < 0.001) and the same was true for the body mass index and height only in men (p < 0.05). The waist circumference, waist-hip ratio, body adiposity index and waist-stature ratio did not differ among the age groups (p > 0.05). the total and peripheral body mass, for the men, in particular, was lower among the older subjects. Central adiposity did not differ among the age groups in both the genders. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

A higher prevalence of insomnia in females has been consistently demonstrated across countries and cultures. The aim of this study was to clarify whether gender differences in insomnia could be explained by gender differences in paid work and family responsibilities. Participants were employees at two local governments in Hokkaido, Japan, who underwent annual health checkups from April 2003 to March 2004. All data were obtained via self-administered questionnaires. Insomnia was evaluated by the Athens Insomnia Scale. For work and family characteristics, occupation, working hours, days off, shift work, visual display terminal (VDT) work, occupational stress, marital status, hours spent on household tasks, childcare, and caregiving were chosen. Data from 7,451 participants (5,951 men and 1,500 women) were analyzed. Logistic regression analysis examined how much paid work and family responsibilities explained gender differences in insomnia. The prevalence of insomnia in female subjects (31.0%) was significantly larger than in males (23.2%), but the gender difference disappeared after adjustment for paid work and family responsibilities. The results of stratified analyses revealed that significant gender differences were found only among workers with comparatively favorable work and family conditions, such as non-shift work, less than 6 h/day of VDT work, exposure to low levels of occupational stress, household tasks for less than 1 h/day, and not living with persons who needed care and support. These results suggest that gender differences in insomnia are explained, in the main, by gender differences in work and family characteristics.

OBJECTIVES The aim of this study was to investigate gender-based differences in nuclear cardiology practice, globally, with particular focus on laboratory volume, radiation dose, protocols, and best practices. BACKGROUND It is unclear if gender-based differences exist in radiation exposure for nuclear cardiology procedures. METHODS In a large multicenter observational cross-sectional study encompassing 7911 patients in 65 countries, radiation effective dose was estimated for each examination. Patient-level best practices relating to radiation exposure were compared between genders. Analysis of covariance was utilized to determine any difference in radiation exposure according to gender, region, and the interaction between gender and region. Linear, logistic, and hierarchical regression models were developed to evaluate gender-based differences in radiation exposure and laboratory adherence to best practices. We also included the United Nations’ gender inequality and human development indices as covariates in multivariable models. RESULTS The proportion of MPI studies performed in women varied between countries, however there was no significant correlation with gender inequality index. Globally, mean effective dose for nuclear cardiology procedures was only slightly lower in women (9.6±4.5 mSv) than in men (10.3±4.5 mSv men, p<0.001), with a difference of only 0.3 mSv in a multivariable model adjusting for patient age and weight. Stress-only imaging was performed more frequently in women (12.5% vs. 8.4%, p<0.001), however camera-based dose-reduction strategies were used less frequently in women (58.6% vs. 65.5%, p<0.001). CONCLUSIONS Despite significant worldwide variation in best practice use and radiation doses from nuclear cardiology procedures, only small differences were observed between genders worldwide. Regional variations noted in MPI use and radiation dose offer potential opportunities to address gender-related differences in delivery of nuclear cardiology care. PMID:27056156
Transgender-inclusive measures of sex/gender for population surveys: Mixed-methods evaluation and recommendations.

Given that an estimated 0.6% of the U.S. population is transgender (trans) and that large health disparities for this population have been documented, government and research organizations are increasingly expanding measures of sex/gender to be trans inclusive. Options suggested for trans community surveys, such as expansive check-all-that-apply gender identity lists and write-in options that offer maximum flexibility, are generally not appropriate for broad population surveys. These require limited questions and a small number of categories for analysis. Limited evaluation has been undertaken of trans-inclusive population survey measures for sex/gender, including those currently in use. Using an internet survey and follow-up of 311 participants, and cognitive interviews from a maximum-diversity sub-sample (n = 79), we conducted a mixed-methods evaluation of two existing measures: a two-step question developed in the United States and a multidimensional measure developed in Canada. We found very low levels of item missingness, and no indicators of confusion on the part of cisgender (non-trans) participants for both measures. However, a majority of interview participants indicated problems with each question item set. Agreement between the two measures in assessment of gender identity was very high (K = 0.9081), but gender identity was a poor proxy for other dimensions of sex or gender among trans participants. Issues to inform measure development or adaptation that emerged from analysis included dimensions of sex/gender measured, whether non-binary identities were trans, Indigenous and cultural identities, proxy reporting, temporality concerns, and the inability of a single item to provide a valid measure of sex/gender. Based on this evaluation, we recommend that population surveys meant for multi-purpose analysis consider a new Multidimensional Sex/Gender Measure for testing that includes three simple items (one asked only of a small sub-group) to assess gender identity and lived gender, with optional additions. We provide considerations for adaptation of this measure to different contexts.

In order to better understand the recent rise in nonprescribed use of psychostimulants on college campuses, motives, outcomes, and acceptability of nonprescribed psychostimulants have been evaluated. Despite knowledge that students use nonprescribed medical stimulants for improved academic performance and recreational use, gender differences in these motives have not been examined, despite the fact that the social construction of gender may well affect motives for use. The goal of the present study was to examine gender differences in motives, outcomes, and acceptability of nonprescribed psychostimulant use. 2716 undergraduates (1448 male) between the ages of 17 and 57 years (M = 19.43 years, SD = 1.7 years) completed an online survey examining subjective motives of nonprescribed psychostimulant use, as well as behaviors after use and moral views of nonprescribed use. Consistent with hypotheses and known gender differences in social motivation, results suggested that while females are more likely to use nonprescribed psychostimulants for reasons related to schoolwork, males are typically more likely to use psychostimulants for reasons related to partying and socializing. Additional gender differences were that males are more likely to take part in other risky behaviors after use of psychostimulants, as well as view nonprescribed use as more moral and less physically dangerous than females. Conclusions/Importance: This work suggests that there are striking gender differences in motivation and outcomes of use of nonprescribed psychostimulants, which may have implications for personalized approaches for prevention of nonprescribed psychostimulant use on campuses based on gender.
Gender-Specificity of Women's and Men's Self-Reported Attention to Sexual Stimuli.

PubMed

Huberman, Jackie S; Maracle, Amanda C; Chivers, Meredith L

2015-01-01

Men's sexual arousal is largely dependent on the actor's gender in a sexual stimulus (gender-specific), whereas for women, particularly androphilic women, arousal is less dependent on gender (gender-nonspecific). According to information-processing models of sexual response, sexual arousal requires that attention be directed toward sexual cues. We evaluated whether men's and women's self-reported attention to sexual stimuli of men or women were consistent with genital responses and self-reported arousal. We presented gynephilic men (n = 21) and women (n = 22) and androphilic men (n = 16) and women (n = 33) with audiovisual stimuli depicting men or women engaged in sexual activities. Genital responses were continuously recorded and, following each stimulus, participants reported the amount of attention paid to the video and feelings of sexual arousal. Self-reported attention was gender-specific for men and gender-nonspecific for women, and generally mirrored genital responses and self-reported arousal. Gender-specificity of genital responses significantly predicted gender-specificity of self-reported arousal; however, for men only, this effect was significantly mediated by gender-specificity of self-reported attention. Gender differences in gender-specificity of sexual arousal may be partially accounted for by differences in gender-specificity of self-reported attention, although attention may play a greater role in men's sexual arousal than women's.

This study evaluated the social behavior of adolescents with attention deficit hyperactivity disorder (ADHD) in single and mixed gender treatment settings. We collected ratings of social behavior (i.e., prosocial peer interactions, assertiveness, self-management, compliance, physical aggression, relational aggression) during single and mixed gender games within the Summer Treatment Program-Adolescent for 10 girls (M age = 13.17, 80% Hispanic) and 11 boys (M age = 12.89, 54.55% Hispanic). Counselors completed ratings immediately following 10 recreational periods for each adolescent they supervised (5 single gender games, 5 mixed gender games). Gender (female vs. male) × Setting (single vs. mixed gender) ANOVAs were conducted. If a significant interaction emerged, post hoc tests were also conducted. Several Gender × Setting interactions emerged, suggesting that girls benefit more from single gender formats than mixed gender formats. Girls showed more assertiveness, self-management, and compliance in single compared to mixed gender settings. A somewhat different pattern of results emerged for boys, which showed more appropriate social behavior (i.e., self-management, compliance) and less inappropriate social behavior (i.e., physical and relational aggression) in mixed gender settings compared to single gender settings. In contrast to previous ADHD treatment studies, these findings suggest that gender may impact treatment response for adolescents. Therefore, it is important that future studies evaluate whether current treatments for ADHD are appropriate for girls with ADHD and whether gender-specific treatments are necessary to address the unique difficulties of adolescent girls with ADHD.

Despite solid basic science research supporting meditation's physiologic benefits, meditation remains a marginalized practice for many Westerners; observational and descriptive studies indicate a spectrum of barriers to meditation practice. The aim of this study was to determine differences in barriers to meditation by gender and age. A cross-sectional survey study of 150 family caregivers to adults with cancer visiting an outpatient chemotherapy center in Connecticut was conducted. The primary outcome was the Determinants of Meditation Practice Inventory. Explanatory variables included demographic characteristics, Center for Epidemiologic Studies-Depression Scale, Big Five Inventory, and Caregiver Reaction Assessment. Participants included 98 women and 52 men. Age range was 18-84 years (M = 52.3 years). The highest frequency of barriers for both genders related to misconceptions about meditation. The total number of barriers to meditation did not significantly vary by gender (p = .10) nor age (p = .27). After adjusting for personality trait, reactions to caregiving, and emotional distress, gender (adjusted β = 0.81, SE = 1.70, p = .63) and age (adjusted β = 0.02, SE = 0.05, p = .67) still did not predict the number of barriers to meditation. Backward elimination in model building showed that personality trait and reactions to caregiving account for 32% of the variability in barriers. The total number of barriers to meditation was examined, and a difference was not found by age or gender. It is possible that differences by age and gender exist at the item level of evaluation but were not evident when evaluating total scores. Further study is needed with samples large enough to have statistical power for item-level analysis.

Purpose To systematically review experimental evidence for interventions mitigating gender bias in employment. Unconscious endorsement of gender stereotypes can undermine academic medicine's commitment to gender equity. Method The authors performed electronic and hand searches for randomized controlled studies since 1973 of interventions that affect gender differences in evaluation of job applicants. Twenty-seven studies met all inclusion criteria. Interventions fell into three categories: application information, applicant features, and rating conditions. Results The studies identified gender bias as the difference in ratings or perceptions of men and women with identical qualifications. Studies reaffirmed negative bias against women being evaluated for positions traditionally or predominantly held by men (male sex-typed jobs). The assessments of male and female raters rarely differed. Interventions that provided raters with clear evidence of job-relevant competencies were effective. However, clearly competent women were rated lower than equivalent men for male sex-typed jobs unless evidence of communal qualities was also provided. A commitment to the value of credentials before review of applicants and women's presence at above 25% of the applicant pool eliminated bias against women. Two studies found unconscious resistance to “antibias” training, which could be overcome with distraction or an intervening task. Explicit employment equity policies and an attractive appearance benefited men more than women, whereas repeated employment gaps were more detrimental to men. Masculine-scented perfume favored the hiring of both sexes. Negative bias occurred against women who expressed anger or who were perceived as self-promoting. Conclusions High-level evidence exists for strategies to mitigate gender bias in hiring. PMID:19881440

The differences in sickness absence between men and women in Sweden have attracted a great deal of interest nationally in the media and among policymakers over a long period. The fact that women have much higher levels of sickness absence has been explained in various ways. These explanations are contextual and one of the theories points to the lack of gender equality as an explanation. In this study, we evaluate the impact of gender equality on health at organizational level. Gender equality is measured by an index ranking companies at organizational level; health is measured as days on sickness benefit. Gender equality was measured using the Organizational Gender Gap Index or OGGI, which is constructed on the basis of six variables accessible in Swedish official registers. Each variable corresponds to a key word illustrating the interim objectives of the "National Plan for Gender Equality", implemented by the Swedish Parliament in 2006. Health is measured by a variable, days on sickness benefit, also accessible in the same registers. We found significant associations between company gender equality and days on sickness benefit. In gender-equal companies, the risk for days on sickness benefit was 1.7 (95% CI 1.6-1.8) higher than in gender-unequal companies. The differences were greater for men than for women: OR 1.8 (95% CI 1.7-2.0) compared to OR 1.4 (95% CI 1.3-1.5). Even though employees at gender-equal companies had more days on sickness benefit, the differences between men and women in this measure were smaller in gender-equal companies. Gender equality appears to alter health patterns, converging the differences between men and women.

The aim was to assess whether the Knee Society Score, Oxford Knee Score (OKS) and Knee Injury and Osteoarthritis Outcome Score (KOOS) were comparable in asymptomatic, healthy, individuals of different age, gender and ethnicity, across two remote continents. The purpose of this study was to establish normal population values for these scores using an electronic data collection system. There is no difference in clinical knee scores in an asymptomatic population when comparing age, gender and ethnicity, across two remote continents. 312 Australian and 314 Canadian citizens, aged 18-94 years, with no active knee pain, injury or pathology in the ipsilateral knee corresponding to their dominant arm, were evaluated. A knee examination was performed and participants completed an electronically administered questionnaire covering the subjective components of the knee scores. The cohorts were age- and gender-matched. Chi-square tests, Fisher's exact test and Poisson regression models were used where appropriate, to investigate the association between knee scores, age, gender, ethnicity and nationality. There was a significant inverse relationship between age and all assessment tools. OKS recorded a significant difference between gender with females scoring on average 1% lower score. There was no significant difference between international cohorts when comparing all assessment tools. An electronic, multi-centre data collection system can be effectively utilized to assess remote international cohorts. Differences in gender, age, ethnicity and nationality should be taken into consideration when using knee scores to compare to pathological patient scores. This study has established an electronic, normal control group for future studies using the Knee society, Oxford, and KOOS knee scores. Diagnostic Level II.

Sex and gender differences exist in the manifestation and prevalence of many conditions and diseases. Yet many clinician training programs neglect to integrate this information across their curricula. This study aimed to measure the sex and gender medical knowledge of medical students enrolled in a program without an explicit directive to integrate sex and gender differences across a block system of core subjects. A forced-choice instrument consisting of 35 multiple-choice and true or false questions was adapted from an evaluation tool used in the European Curriculum in Gender Medicine held at Charité Hospital, Berlin, in September 2010. Fourth-year (response rate 93%) and second-year (response rate 70%) students enrolled in Mayo Medical School completed the instrument. More than 50% of students in both classes indicated that topics related to sex and gender were covered in gynecology, cardiology, and pediatrics, and <20% of students indicated inclusion of such topics in nephrology, neurology, and orthopedics. More than twice as many second-year students indicated that topics dealing with sex and gender were included in immunology course material compared with fourth-year students. A consensus of written comments indicated that concepts of sex and gender-based medicine need to be embedded into existing curriculum, with an emphasis on clinically relevant information. Although this study represents only one medical school in the United States, information regarding sex and gender aspects of medicine is not consistently included in this curriculum without an explicit directive. These results can provide guidance for curriculum improvement to train future physicians. Copyright © 2012 Elsevier HS Journals, Inc. All rights reserved.

Research and development increasingly apply participatory approaches that involve both stakeholders and scientists. This article presents an evaluation of German and Tanzanian researchers' perceptions during their activities as part of a large interdisciplinary research project in Tanzania. The project focused on prioritizing and implementing food-securing upgrading strategies across the components of rural food value chains. The participants involved during the course of the project were asked to provide feedback on 10 different research steps and to evaluate eight core features related to the functioning and potential shortcomings of the project. The study discriminated among evaluation differences linked to culture, gender, and institutional status. Perceptions differed between Tanzanian and German participants depending on the type and complexity of the participatory research steps undertaken and the intensity of stakeholder participation. There were differences in perception linked to gender and hierarchical status; however, those differences were not as concise and significant as those linked to nationality. These findings indicate that participatory action research of this nature requires more targeted strategies and planning tailored to the type of activity. Such planning would result in more efficient and satisfactory communication, close collaboration, and mutual feedback to avoid conflicts and other problems. We further conclude that it would be advisable to carefully incorporate training on these aspects into future project designs.
Quality of evidence revealing subtle gender biases in science is in the eye of the beholder.

Scientists are trained to evaluate and interpret evidence without bias or subjectivity. Thus, growing evidence revealing a gender bias against women-or favoring men-within science, technology, engineering, and mathematics (STEM) settings is provocative and raises questions about the extent to which gender bias may contribute to women's underrepresentation within STEM fields. To the extent that research illustrating gender bias in STEM is viewed as convincing, the culture of science can begin to address the bias. However, are men and women equally receptive to this type of experimental evidence? This question was tested with three randomized, double-blind experiments-two involving samples from the general public (n = 205 and 303, respectively) and one involving a sample of university STEM and non-STEM faculty (n = 205). In all experiments, participants read an actual journal abstract reporting gender bias in a STEM context (or an altered abstract reporting no gender bias in experiment 3) and evaluated the overall quality of the research. Results across experiments showed that men evaluate the gender-bias research less favorably than women, and, of concern, this gender difference was especially prominent among STEM faculty (experiment 2). These results suggest a relative reluctance among men, especially faculty men within STEM, to accept evidence of gender biases in STEM. This finding is problematic because broadening the participation of underrepresented people in STEM, including women, necessarily requires a widespread willingness (particularly by those in the majority) to acknowledge that bias exists before transformation is possible.

Increased metabolism in the left auditory cortex has been reported in tinnitus patients. However, gender difference has not been addressed. To assess the differences in Positron emission tomography-computed tomography (PET-CT) results between the genders in tinnitus patients. Retrospective cohort. Included were patients referred to our clinic between January 2011 and August 2013 who complained of tinnitus and underwent fluorodeoxyglucose (FDG)-PET to assess brain metabolism. Univariate and multivariate nominal logistic regressions were used to evaluate the association between upper temporal gyrus (UTG; right and left) and gender. Included were 140 patients (87 males) with an average age of 52.5 yr (median = 53.1). Bilateral tinnitus was found in 85 patients (60.7%), left sided in 30 (21.4%), and right sided in 21(15%). Increased uptake in the UTG was found in 60% of the patients on either side. Males had a statistically significant increased uptake in the UTG in those with unilateral tinnitus and in the entire population. We present the largest study reported so far on tinnitus patients who have undergone FDG-PET-CT. We found a statistically significant difference between the genders in FDG uptake by the UTG. Further investigations should be undertaken to reveal the etiologies for these differences and to assess different therapeutic protocols according to gender. American Academy of Audiology

Study Objectives: Studies have shown pharmacokinetic differences for hypnotics in women compared to men, but few studies have assessed either short-or long-term differences in efficacy and safety. Methods: To evaluate gender differences in the efficacy and safety of chronic nightly zolpidem (10 mg), we did a post hoc assessment of a large clinical trial. In the trial, participants with primary insomnia (n = 89), ages 23–70, meeting DSM-IV-TR criteria for primary insomnia were randomized, double blind, to nightly zolpidem, 10 mg (n = 47) or placebo (n = 42) 30 minutes before bedtime nightly for 12 months. Polysomnographic sleep on 2 nights in months 1 and 8 and likelihood of next-day sleepiness, rebound insomnia, and dose escalation were evaluated in months 1, 4, and 12. Results: Relative to placebo, zolpidem significantly increased sleep efficiency and reduced sleep latency and wake after sleep onset assessed at months 1 and 8, with no differences in efficacy between women and men and no diminution of efficacy over months. On a next-day multiple sleep latency test (MSLT), no residual sedation was observed for either women or men. No rebound insomnia or dose escalation was seen with no gender differences in either. Conclusions: In adults with primary insomnia, nightly zolpidem administration showed no gender differences in acute or chronic efficacy or in next-day sleepiness. Zolpidem remained efficacious and safe across 12 months.

Despite increased attention to the evolving nature of war, the unique challenges of contemporary deployment, and women's changing role in warfare, few studies have examined differences in deployment stressors across eras of service or evaluated how gender differences in deployment experiences have changed over time. Using data collected from two national survey studies, we examined war cohort and gender differences in veterans' reports of both mission-related and interpersonal stressors during deployment. Although Operation Enduring Freedom and Operation Iraqi Freedom veterans reported more combat experiences and greater preparedness for deployment compared to Gulf War veterans, Gulf War veterans reported higher levels of other mission-related stressors, including difficult living and working environment, perceived threat, and potential exposure to nuclear, biological, and chemical weapons. Gender differences also emerged, with men reporting greater exposure to mission-related stressors and women reporting higher levels of interpersonal stressors. However, the size and nature of gender differences did not differ significantly when comparing veterans of the two eras. By understanding how risk factors for PTSD differ based on war era and gender, veterans' experiences can be better contextualized. (c) 2016 APA, all rights reserved).

This study aimed to evaluate the effects of the gender-role types and child-rearing gender-role attitude of the single-parents, as well as their children's gender role traits and family socio-economic status, on social adjustment. We recruited 458 pairs of single parents and their children aged 8-18 by purposive sampling. The research tools included the Family Socio-economic Status Questionnaire, Sex Role Scales, Parental Child-rearing Gender-role Attitude Scale and Social Adjustment Scale. The results indicated: (a) single mothers' and their daughters' feminine traits were both higher than their masculine traits, and sons' masculine traits were higher than their feminine traits; the majority gender-role type of single parents and their children was androgyny; significant differences were found between children's gender-role types depending on different raiser, the proportion of girls' masculine traits raised by single fathers was significantly higher than those who were raised by single mothers; (b) family socio-economic status and single parents' gender-role types positively influenced parental child-rearing gender-role attitude, which in turn, influenced the children's gender traits, and further affected children's social adjustment. © 2018 International Union of Psychological Science.

The present study evaluated gender role theory as an explanation for the observed gender differences in anxiety symptoms among adolescents. Specifically, the relation between gender, gender role orientation (i.e., masculinity and femininity), self-esteem, and anxiety symptoms was examined in a community sample of 114 African Americans aged 14 to 19 (mean age 15.77; 57 girls). Results revealed that masculinity was negatively associated with anxiety symptoms whereas femininity was positively associated with anxiety symptoms. Gender role orientation accounted for unique variance in anxiety scores above biological gender and self-esteem, and self-esteem moderated the relation between femininity (but not masculinity) and overall anxiety symptoms. Consistent with research on children and Caucasians, findings supported gender role theory as a partial explanation for the observed gender disparity in anxiety symptoms among African American adolescents.

We examined the evaluations given by nurses to obstetrics and gynecology residents to estimate whether gender bias was evident. Women receive more negative feedback and evaluations than men-from both sexes. Some suggest that, to be successful in traditionally male roles such as surgeon, women must manifest a warmth-related (communal) rather than competence-related (agentic) demeanor. Compared with male residents, female residents experience more interpersonal difficulties and less help from female nurses. We examined feedback provided to residents by female nurses. We examined Professional Associate Questionnaires (2006-2014) using a mixed-methods design. We compared scores per training year by gender using Mann-Whitney and linear regression adjusting for resident and nurse cohorts. Using grounded theory analysis, we developed a coding system for blinded comments based on principles of effective feedback, medical learners' evaluation, and impression management. χ examined the proportions of negative and positive and communal and agentic comments between genders. We examined 2,202 evaluations: 397 (18%) for 10 men and 1,805 (82%) for 34 women. Twenty-three compliments (eg, "Great resident!") were excluded. Evaluations per training year varied: men n=77-134; women n=384-482. Postgraduate year (PGY)-1, PGY-2, and PGY-4 women had lower mean ratings (P<.035); when adjusted, the difference remained significant in PGY-2 (MWomen=1.5±0.6 compared with MMen=1.7±0.5; P=.001). Postgraduate year-1 women received disproportionately fewer positive and more negative agentic comments than PGY-1 men (positive=17.3% compared with 40%, negative=17.3% compared with 3.3%, respectively; P=.041). Evidence of gender bias in evaluations emerged; albeit subtle, women received harsher feedback as lower-level residents than men. Training in effective evaluation and gender bias management is warranted.

Growing evidence suggests that gender-blind assessment of exposure may introduce exposure misclassification, but few studies have characterised gender differences across occupations and industries. We pooled control responses to job-specific, industry-specific and exposure-specific questionnaires (modules) that asked detailed questions about work activities from three US population-based case-control studies to examine gender differences in work tasks and their frequencies. We calculated the ratio of female-to-male controls that completed each module. For four job modules (assembly worker, machinist, health professional, janitor/cleaner) and for subgroups of jobs that completed those modules, we evaluated gender differences in task prevalence and frequency using χ(2) and Mann-Whitney U tests, respectively. The 1360 female and 2245 male controls reported 6033 and 12 083 jobs, respectively. Gender differences in female:male module completion ratios were observed for 39 of 45 modules completed by ≥20 controls. Gender differences in task prevalence varied in direction and magnitude. For example, female janitors were significantly more likely to polish furniture (79% vs 44%), while male janitors were more likely to strip floors (73% vs 50%). Women usually reported more time spent on tasks than men. For example, the median hours per week spent degreasing for production workers in product manufacturing industries was 6.3 for women and 3.0 for men. Observed gender differences may reflect actual differences in tasks performed or differences in recall, reporting or perception, all of which contribute to exposure misclassification and impact relative risk estimates. Our findings reinforce the need to capture subject-specific information on work tasks. Published by the BMJ Publishing Group Limited.

The aim of this study was to assess the impact of two teaching interventions (ultrasound and arthroscopy) in a peer teaching (PT) environment on anatomy examination scores and also to examine the influence of gender and learning style on these scores. We randomly assigned 484 second year medical students to one of three groups: musculoskeletal ultrasound (MSUS), arthroscopy (ASC) and control (CON). The MSUS- and the ASC-group attended two additional training sessions in ultrasound or arthroscopy; the CON-group received no additional lessons. Students were asked to complete Kolb's Learning Style Inventory test. We assessed differences in anatomical knowledge (multiple choice (MC) exam) and subjective evaluation with respect to gender and learning style. There were no relevant differences between the three groups regarding the MC exam. Acceptance of the peer teaching concept was good. All students preferred ultrasound to arthroscopy and thought that they learned more from ultrasound despite the fact that they rated the instructors as less competent and needed more time to gain in-depth knowledge. There was no significant effect of gender on evaluation results. Arthroscopy was best enjoyed by accommodators according to Kolb's Inventory and least by divergers, who found that they had learned a lot through ultrasound. The improvement in spatial conceptualization was greatest for accommodators and worst for assimilators. Gender and learning style had no impact on quantitative parameters. Qualitative analysis, however, revealed differences for learning style and further evaluation is warranted to assess the impact on medical education. Copyright © 2016 Elsevier GmbH.

The incidence of urothelial carcinoma of the bladder (UCB) is lower in women; however, women tend to present with more advanced disease. To date, there is no quantitative synthesis of studies reporting gender-specific outcomes in non-muscle-invasive UCB. To conduct a meta-analysis evaluating gender-specific differences in recurrence of non-muscle-invasive urinary bladder cancer (NMIBC). An unrestricted systematic literature search of the MEDLINE, EMBASE, and Cochrane libraries was conducted. Studies evaluating the impact of gender on disease recurrence after local treatment of NMIBC using multivariable Cox proportional hazard models were included. Random effect meta-analysis, subgroup analyses, meta-influence, and cumulative meta-analyses were conducted. Publication bias was assessed via a funnel plot and Eggeŕs test. Of 609 studies screened, 27 comprising 23 754 patients were included. Random effect meta-analyses indicated women at increased risk for UCB recurrence compared with men (hazard ratio [HR]=1.11, 95% confidence interval [CI]: 1.01-1.23, p=0.03). Subgroup analyses yielded estimates between HR=0.99 and HR=1.68. Gender-specific differences in UCB recurrence were most pronounced in studies administering exclusively bacillus Calmette-Guerin (BCG; HR=1.64, 95% CI: 1.13-2.39, p=0.01), especially in a long-term treatment regimen (HR=1.68, 95% CI: 1.32-2.15, p<0.001). Sensitivity analyses confirmed female patients at increased risk for UCB recurrence. Women are at increased risk for disease recurrence after local treatment of NMIBC compared with male patients. Reduced effectiveness of BCG treatment might underlie this observation. Gender-specific differences were evident across various subgroups and proved robust upon sensitivity analyses. In this report, we combined several studies on gender-specific differences in relapse of superficial bladder cancer. Women were more likely to experience cancer relapse than men.

In order to provide standard values for craniofacial growth of normal children, we evaluated the growth changes of skeletal and soft tissue cephalometric landmarks from lateral cephalograms of 180 Japanese children. They were divided into three groups: primary dentition, mixed dentition, and permanent dentition. Specific skeletal angles and distances showed significant gender differences with increasing age. The only significant soft tissue gender difference was nose height in the oldest group. Upper pharynx dimension and nose height differed significantly among the groups in both genders. Positions of both the upper and lower lip changed significantly between the intermediate and oldest groups of both genders. Nasolabial angle did not change significantly with growth. The results of this study should be useful for predicting craniofacial growth and development or determining the effect of orthodontic treatment.
Orienting to face expression during encoding improves men's recognition of own gender faces.

PubMed

Fulton, Erika K; Bulluck, Megan; Hertzog, Christopher

2015-10-01

It is unclear why women have superior episodic memory of faces, but the benefit may be partially the result of women engaging in superior processing of facial expressions. Therefore, we hypothesized that orienting instructions to attend to facial expression at encoding would significantly improve men's memory of faces and possibly reduce gender differences. We directed 203 college students (122 women) to study 120 faces under instructions to orient to either the person's gender or their emotional expression. They later took a recognition test of these faces by either judging whether they had previously studied the same person or that person with the exact same expression; the latter test evaluated recollection of specific facial details. Orienting to facial expressions during encoding significantly improved men's recognition of own-gender faces and eliminated the advantage that women had for male faces under gender orienting instructions. Although gender differences in spontaneous strategy use when orienting to faces cannot fully account for gender differences in face recognition, orienting men to facial expression during encoding is one way to significantly improve their episodic memory for male faces.

Performance-based alternative assessments as a means of eliminating gender achievement differences on science tests

NASA Astrophysics Data System (ADS)

Brown, Norman Merrill

1998-09-01

Historically, researchers have reported an achievement difference between females and males on standardized science tests. These differences have been reported to be based upon science knowledge, abstract reasoning skills, mathematical abilities, and cultural and social phenomena. This research was designed to determine how mastery of specific science content from public school curricula might be evaluated with performance-based assessment models, without producing gender achievement differences. The assessment instruments used were Harcourt Brace Educational Measurement's GOALSsp°ler: A Performance-Based Measure of Achievement and the performance-based portion of the Stanford Achievement Testspcopyright, Ninth Edition. The identified independent variables were test, gender, ethnicity, and grade level. A 2 x 2 x 6 x 12 (test x gender x ethnicity x grade) factorial experimental design was used to organize the data. A stratified random sample (N = 2400) was selected from a national pool of norming data: N = 1200 from the GOALSsp°ler group and N = 1200 from the SAT9spcopyright group. The ANOVA analysis yielded mixed results. The factors of test, gender, ethnicity by grade, gender by grade, and gender by grade by ethnicity failed to produce significant results (alpha = 0.05). The factors yielding significant results were ethnicity, grade, and ethnicity by grade. Therefore, no significant differences were found between female and male achievement on these performance-based assessments.

Cerebrovascular neurologic emergencies including ischemic and hemorrhagic stroke, subarachnoid hemorrhage (SAH), and migraine are leading causes of death and disability that are frequently diagnosed and treated in the emergency department (ED). Although sex and gender differences in neurologic emergencies are beginning to become clearer, there are many unanswered questions about how emergency physicians should incorporate sex and gender into their research initiatives, patient evaluations, and overall management plans for these conditions. After evaluating the existing gaps in the literature, a core group of ED researchers developed a draft of future research priorities. Participants in the 2014 Academic Emergency Medicine consensus conference neurologic emergencies working group then discussed and approved the recommended research agenda using a standardized nominal group technique. Recommendations for future research on the role of sex and gender in the diagnosis, treatment, and outcomes pertinent to ED providers are described for each of three diagnoses: stroke, SAH, and migraine. Recommended future research also includes investigation of the biologic and pathophysiologic differences between men and women with neurologic emergencies as they pertain to ED diagnoses and treatments. © 2014 by the Society for Academic Emergency Medicine.

Background: Gender difference has been reported in stroke risk factors and disease history. The aim of this study was to compare risk factors and the severity of ischemic stroke based upon modified Rankin Scale (mRS) and hospital mortality between two genders. Methods: In a cross-sectional study, 341 patients (44% males and 56% females with a mean age of 68.94 ± 12.74 years) with ischemic stroke, who were hospitalized in the neurology wards of two referral university hospital of North-West Iran (Imam Reza and Razi Hospitals), from the beginning to the end of 2011 were selected and assessed. Gender difference in terms of demographic findings, vascular risk factors, 7th day mRS, and hospital mortality (during admission) were evaluated. Results: In 2.6% of cases, mRS was found to be less than 2 (favorable) and in 97.4% of cases; mRS was 2-5 (with disability). No significant difference in ischemic stroke severity based on mRS was observed between two genders. There was a significant difference in the rate of hypertension (females = 72.3%, males = 59.3%, P = 0.010), diabetes (females = 28.8%, males = 18.7%, P = 0.030), smoking (females = 6.3%, males = 35.3%, P < 0.001). No significant difference was seen in other risk factors between two genders. There was no significant difference in the mortality rate, which constituted 8.9% and 4.7% in females and males respectively (P = 0.140). Conclusion: The evidence from the present study suggests that despite the existence of some difference between risk-factors in two genders, there was no difference in terms of ischemic stroke severity and mortality rate between two genders.

This study evaluates the issue of gender-based pay inequality. Male NHAs earn 7 percent more than female NHAs, but factors such as education, experience, tenure, facility size, ownership, location, competition, and emphasis on private pay census account for the difference. The findings, however, indicate that racial inequalities and gender differences among married NHAs may be present, requiring further investigation. Key implications of the results are discussed.

Assessment of the influence of gender and increasing years at university on sleep health of students. Four hundred and eighteen students from different streams across years of undergraduate to postgraduate courses participated. Descriptive statistics, test of differences, and correlation were used. The sleep health data comprised of subjective evaluation using a questionnaire and personal interviews. Overall, 43.1% had sleep problems, females were more affected (51.67% vs. 48.33% in males) but were early bed goers. The prevalence of circadian rhythm sleep disorder (11.6% vs. 9.5%) and delayed sleep phase syndrome (4.5% vs. 2.7%) was slightly higher in males. The daytime dysfunction and hypnotic use significantly differed in students of the same class among gender. Bedtime got significantly delayed along years [H(2)=29.769, p<0.001], and hypnotic use [H(2)=8.807, p=0.012] differed significantly among them. The moderate-very strong correlational statistics among sleep health elements was very similar across gender and years of university education. However, more pronounced influence of years of university education than gender was seen in the significant differences for correlated correlation among sleep health parameters. Gender and years of university education influence sleep among university students both separately and concomitantly.

Multiple research studies show that there appears to be an inherent difference between male and female students' performance on the Force Concept Inventory (FCI). Unlike these studies, we chose to create two different samples, one with only female students and the other with only male students, to reduce the effects of the gender-imbalance inherent in a single sample of all physics students. Using a psychometric lens, we evaluate the differences between the male and female students' performance on the FCI. We utilized classical test theory to flag 13 items on the FCI that were poorly functioning for female students. Notably, most of these items were not flagged when the dataset was aggregated across genders. In the next stage of the research, we utilized Item Response Theory (IRT) to discover if the remaining 17 items on the FCI are also poorly functioning for female students. By eliminating the poorly functioning items on the FCI, we further examined the gender difference of the Force Concept Inventory.

Gender differences in treatment that are not supported by empirical evidence have been reported in several areas of medicine. Here, the aim was to evaluate potential gender differences in the treatment for bipolar disorder. Data was collected from the Swedish National Quality Assurance Register for bipolar disorder (BipoläR). Baseline registrations from the period 2004-2011 of 7354 patients were analyzed. Multiple logistic regression analysis was used to study the impact of gender on interventions. Women were more often treated with antidepressants, lamotrigine, electroconvulsive therapy, benzodiazepines, and psychotherapy. Men were more often treated with lithium. There were no gender differences in treatment with mood stabilizers as a group, neuroleptics, or valproate. Subgroup analyses revealed that ECT was more common in women only in the bipolar I subgroup. Contrariwise, lamotrigine was more common in women only in the bipolar II subgroup. As BipoläR contains data on outpatient treatment of persons with bipolar disorder in Sweden, it is unclear if these findings translate to inpatient care and to outpatient treatment in other countries. Men and women with bipolar disorder receive different treatments in routine clinical settings in Sweden. Gender differences in level of functioning, bipolar subtype, or severity of bipolar disorder could not explain the higher prevalence of pharmacological treatment, electroconvulsive therapy, and psychotherapy in women. Our results suggest that clinicians׳ treatment decisions are to some extent unduly influenced by patients׳ gender. Copyright © 2014 Elsevier B.V. All rights reserved.

The aim of the current review was to examine the scope of studies published in the Science of Salt Weekly that contained a measure of self-reported knowledge, attitudes, and behavior (KAB) concerning salt. Specific objectives were to examine how KAB measures are used to evaluate salt reduction intervention studies, the questionnaires used, and whether any gender differences exist in self-reported KAB. Studies were reviewed from the commencement of Science of Salt Weekly, June 2013 to the end of August 2017. Seventy-five studies had relevant measures of KAB and were included in this review, 13 of these were salt-reduction intervention-evaluation studies, with the remainder (62) being descriptive KAB studies. The KAB questionnaires used were specific to the populations studied, without evidence of a best practice measure. 40% of studies used KAB alone as the primary outcome measure; the remaining studies used more quantitative measures of salt intake such as 24-hour urine. Only half of the descriptive studies showed KAB outcomes disaggregated by gender, and of those, 73% showed women had more favorable KAB related to salt. None of the salt intervention-evaluation studies showed disaggregated KAB data. Therefore, it is likely important that evaluation studies disaggregate, and are appropriately powered to disaggregate all outcomes by gender to address potential disparities. ©2018 Wiley Periodicals, Inc.

Background: Several studies suggest that test characteristics for the fecal immunochemical test (FIT) differ by gender, triggering a debate on whether men and women should be screened differently. We used the microsimulation model MISCAN-Colon to evaluate whether screening stratified by gender is cost-effective. Methods: We estimated gender-specific FIT characteristics based on first-round positivity and detection rates observed in a FIT screening pilot (CORERO-1). Subsequently, we used the model to estimate harms, benefits, and costs of 480 gender-specific FIT screening strategies and compared them with uniform screening. Results: Biennial FIT screening from ages 50 to 75 was less effective in women than men [35.7 vs. 49.0 quality-adjusted life years (QALY) gained, respectively] at higher costs (€42,161 vs. -€5,471, respectively). However, the incremental QALYs gained and costs of annual screening compared with biennial screening were more similar for both genders (8.7 QALYs gained and €26,394 for women vs. 6.7 QALYs gained and €20,863 for men). Considering all evaluated screening strategies, optimal gender-based screening yielded at most 7% more QALYs gained than optimal uniform screening and even resulted in equal costs and QALYs gained from a willingness-to-pay threshold of €1,300. Conclusions: FIT screening is less effective in women, but the incremental cost-effectiveness is similar in men and women. Consequently, screening stratified by gender is not more cost-effective than uniform FIT screening. Impact: Our conclusions support the current policy of uniform FIT screening.

The aim of this study was to assess the impact of different teaching interventions in a peer-teaching environment on basic echocardiography skills and to examine the influence of gender on learning outcomes. We randomly assigned 79 s year medical students (55 women, 24 men) to one of four groups: peer teaching (PT), peer teaching using Peyton's four-step approach (PPT), team based learning (TBL) and video-based learning (VBL). All groups received theoretical and practical hands-on training according to the different approaches. Using a pre-post-design we assessed differences in theoretical knowledge [multiple choice (MC) exam], practical skills (Objective Structured Practical Examination, OSPE) and evaluation results with respect to gender. There was a significant gain in theoretical knowledge for all students. There were no relevant differences between the four groups regarding the MC exam and OSPE results. The majority of students achieved good or very good results. Acceptance of the peer-teaching concept was moderate and all students preferred medical experts to peer tutors even though the overall rating of the instructors was fairly good. Students in the Video group would have preferred a different training method. There was no significant effect of gender on evaluation results. Using different peer-teaching concepts proved to be effective in teaching basic echocardiography. Gender does not seem to have an impact on effectiveness of the instructional approach. Qualitative analysis revealed limited acceptance of peer teaching and especially of video-based instruction.

This paper presents a computer-aided platform, named Virtual Hospital (VH), to evaluate the wayfinding ability that is found impaired in senile people with early dementia. The development of the VH takes the advantage of virtual reality technology to make the evaluation of the sense of direction more convenient and accurate then the conventional way. A pilot study was carried out to test its feasibility in differentiating the sense of direction between different genders. The results with significant differences in the response time (p<0.05) and the pointing error (p<0.01) between genders suggest the potential of the VH for clinical uses. Further improvement on the human-machine interface is necessary to make it easy for geriatric people to use.
Quality of evidence revealing subtle gender biases in science is in the eye of the beholder

Scientists are trained to evaluate and interpret evidence without bias or subjectivity. Thus, growing evidence revealing a gender bias against women—or favoring men—within science, technology, engineering, and mathematics (STEM) settings is provocative and raises questions about the extent to which gender bias may contribute to women’s underrepresentation within STEM fields. To the extent that research illustrating gender bias in STEM is viewed as convincing, the culture of science can begin to address the bias. However, are men and women equally receptive to this type of experimental evidence? This question was tested with three randomized, double-blind experiments—two involving samples from the general public (n = 205 and 303, respectively) and one involving a sample of university STEM and non-STEM faculty (n = 205). In all experiments, participants read an actual journal abstract reporting gender bias in a STEM context (or an altered abstract reporting no gender bias in experiment 3) and evaluated the overall quality of the research. Results across experiments showed that men evaluate the gender-bias research less favorably than women, and, of concern, this gender difference was especially prominent among STEM faculty (experiment 2). These results suggest a relative reluctance among men, especially faculty men within STEM, to accept evidence of gender biases in STEM. This finding is problematic because broadening the participation of underrepresented people in STEM, including women, necessarily requires a widespread willingness (particularly by those in the majority) to acknowledge that bias exists before transformation is possible.

The objective of this study is to better understand salivary and masticatory characteristics, this study evaluated the relationship among salivary parameters, bite force (BF), masticatory performance (MP) and gustatory sensitivity in healthy children. The secondary outcome was to evaluate possible gender differences. One hundred and sixteen eutrophic subjects aged 7-11 years old were evaluated, caries-free and with no definite need of orthodontic treatment. Salivary flow rate and pH, total protein (TP), alpha-amylase (AMY), calcium (CA) and phosphate (PHO) concentrations were determined in stimulated (SS) and unstimulated saliva (US). BF and MP were evaluated using digital gnathodynamometer and fractional sieving method, respectively. Gustatory sensitivity was determined by detecting the four primary tastes (sweet, salty, sour and bitter) in three different concentrations. Data were evaluated using descriptive statistics, Mann-Whitney/t-test, Spearman correlation and multiple regression analysis, considering α = 0.05. Significant positive correlation between taste and age was observed. CA and PHO concentrations correlated negatively with salivary flow and pH; sweet taste scores correlated with AMY concentrations and bitter taste sensitivity correlated with US flow rate (p < 0.05). No significant difference between genders in salivary, masticatory characteristics and gustatory sensitivity was observed. The regression analysis showed a weak relationship between the distribution of chewed particles among the different sieves and BF. The concentration of some analytes was influenced by salivary flow and pH. Age, saliva flow and AMY concentrations influenced gustatory sensitivity. In addition, salivary, masticatory and taste characteristics did not differ between genders, and only a weak relation between MP and BF was observed.
Gender and engineering aptitude: Is the color of science, technology, engineering, and math materials related to children's performance?

Mulvey, Kelly Lynn; Miller, Bridget; Rizzardi, Victoria

2017-08-01

To investigate gender stereotypes, demonstrated engineering aptitude, and attitudes, children (N=105) solved an engineering problem using either pastel-colored or primary-colored materials. Participants also evaluated the acceptability of denial of access to engineering materials based on gender and counter-stereotypic preferences (i.e., a boy who prefers pastel-colored materials). Whereas material color was not related to differences in female participants' performance, younger boys assigned to pastel materials demonstrated lower engineering aptitude than did other participants. In addition, results documented age- and gender-related differences; younger participants, and sometimes boys, exhibited less flexibility regarding gender stereotypes than did older and female participants. The findings suggest that attempts to enhance STEM (science, technology, engineering, and math) engagement or performance through the color of STEM materials may have unintended consequences.

Social categories shape children's lives in subtle and powerful ways. Although research has assessed children's knowledge of social groups, most prominently race and gender, few studies have examined children's understanding of their own multiple social identities and how they intersect. This paper explores how children evaluate the importance and meaning of their racial and gender identities, and variation in these evaluations based on the child's own age, gender, and race. Participants were 222 Black, White, and Mixed-Race children (girls: n = 136; Mage = 9.94 years). Data were gathered in schools via 1-on-1 semistructured interviews. Analyses focused on specific measures of the importance and meaning of racial and gender identity for children. We found that: (a) children rate gender as a more important identity than race; (b) the meanings children ascribe to gender identity emphasized inequality and group difference whereas the meaning of race emphasized physical appearance and humanism/equality; and (c) children's assessments of importance and meaning varied as a function of child race and gender, but not age. The findings extend research on young children's social identity development and the role of culture and context in children's emerging racial and gender identities. Implications for identity theory and development and intergroup relations are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

The aim of this study was to investigate gender-based differences in nuclear cardiology practice globally, with a particular focus on laboratory volume, radiation dose, protocols, and best practices. It is unclear whether gender-based differences exist in radiation exposure for nuclear cardiology procedures. In a large, multicenter, observational, cross-sectional study encompassing 7,911 patients in 65 countries, radiation effective dose was estimated for each examination. Patient-level best practices relating to radiation exposure were compared between genders. Analysis of covariance was used to determine any difference in radiation exposure according to gender, region, and the interaction between gender and region. Linear, logistic, and hierarchical regression models were developed to evaluate gender-based differences in radiation exposure and laboratory adherence to best practices. The study also included the United Nations Gender Inequality Index and Human Development Index as covariates in multivariable models. The proportion of myocardial perfusion imaging studies performed in women varied among countries; however, there was no significant correlation with the Gender Inequality Index. Globally, mean effective dose for nuclear cardiology procedures was only slightly lower in women (9.6 ± 4.5 mSv) than in men (10.3 ± 4.5 mSv; p < 0.001), with a difference of only 0.3 mSv in a multivariable model adjusting for patients' age and weight. Stress-only imaging was performed more frequently in women (12.5% vs. 8.4%; p < 0.001); however, camera-based dose reduction strategies were used less frequently in women (58.6% vs. 65.5%; p < 0.001). Despite significant worldwide variation in best practice use and radiation doses from nuclear cardiology procedures, only small differences were observed between genders worldwide. Regional variations noted in myocardial perfusion imaging use and radiation dose offer potential opportunities to address gender-related differences in delivery of nuclear cardiology care.

Sissies, Mama's Boys, and Tomboys: Is Children's Gender Nonconformity More Acceptable When Nonconforming Traits Are Positive?

PubMed

Coyle, Emily F; Fulcher, Megan; Trübutschek, Darinka

2016-10-01

The evaluation of gender nonconformity in children was examined in two studies. In Study 1, 48 young adults evaluated the positivity of culturally popular labels for gender nonconformity, including "tomboy," "sissy," and two new labels generated in a pilot study, "mama's boy" and "brat." The "mama's boy" was described as a boy who has positive feminine traits (gentle and well-mannered) as opposed to the "sissy" who was described as having negative feminine traits (crying and easily frightened). In Study 2, 161 young adults read descriptions of gender-typical and nonconforming children, evaluating them in several domains. The label "mama's boy" was considered negative in Study 1 but an unlabeled positive nonconforming boy was rated as likable and competent in Study 2. However, participants worried about nonconforming boys, saying they would encourage them to behave differently and describing such children with derogatory sexual orientation slurs. "Tomboy" was generally considered a positive label in Study 1. In Study 2, gender nonconforming girls were considered neither likable nor dislikeable, and neither competent nor incompetent, reflecting ambivalence about girls' nonconformity. It may be that we use gender nonconformity labels as indicators of sexual orientation, even in young children. Therefore, even when an individual displays objectively positive traits, the stigma associated with homosexuality taints judgments about their nonconforming behavior.
The Effect of Gender on Resident Autonomy in the Operating room.

Meyerson, Shari L; Sternbach, Joel M; Zwischenberger, Joseph B; Bender, Edward M

Discrimination against women training in medicine and surgery has been subjectively described for decades. This study objectively documents gender differences in the degree of autonomy given to thoracic surgery trainees in the operating room. Thoracic surgery residents and faculty underwent frame of reference training on the use of the 4-point Zwisch scale to measure operative autonomy. Residents and faculty then submitted evaluations of their perception of autonomy granted for individual operations as well as operative difficulty on a real-time basis using the "Zwisch Me!!" mobile application. Differences in autonomy given to male and female residents were elucidated using chi-square analysis and ordered logistic regression. Seven academic medical centers with thoracic surgery training programs. Volunteer thoracic surgery residents in both integrated and traditional training pathways and their affiliated cardiothoracic faculty. Residents (n = 33, female 18%) submitted a total of 596 evaluations to faculty (n = 48, female 12%). Faculty gave less autonomy to female residents with only 56 of 184 evaluations (30.3%) showing meaningful autonomy (passive help or supervision only) compared to 107 of 292 evaluations (36.7%) at those levels for male residents (p = 0.02). Resident perceptions of autonomy showed even more pronounced differences with female residents receiving only 38 of 197 evaluations (19.3%) with meaningful autonomy compared to 133 of 399 evaluations (33.3%) for male residents (p < 0.001). Potential influencing factors explored included attending gender and specialty, case type and difficulty, and resident level of training. In multivariate analysis, only case difficultly, resident gender, and level of training were significantly related to autonomy granted to residents. Evaluations of operative autonomy reveal a significant bias against female residents. Faculty education is needed to encourage allowing female residents more operative autonomy.

To evaluate the impact of sex reassignment surgery on the defense mechanisms of 32 transsexual patients at two different points in time using the Defensive Style Questionnaire. The Defensive Style Questionnaire was applied to 32 patients upon their admission to the Gender Identity Disorder Program, and 12 months after they had undergone sex reassignment surgery. There were changes in two defense mechanisms: anticipation and idealization. However, no significant differences were observed in terms of the mature, neurotic and immature categories. One possible explanation for this result is the fact that the procedure does not resolve gender dysphoria, which is a core symptom in such patients. Another aspect is related to the early onset of the gender identity disorder, which determines a more regressive defensive structure in these patients. Sex reassignment surgery did not improve the defensive profile as measured by the Defensive Style Questionnaire.

Twelve patients (six female and six male) with histologically proven glioblastoma multiforme were investigated during the administration of the first cycle of dacarbazine (D; 200 mg/m) and fotemustine (F; 100 mg/m). In total, 18 blood samples were collected for pharmacokinetic analysis (maximum plasma concentration, area under the concentration-time curve and total clearance) of D and F at 14 time points during therapy. D, its metabolite 5-aminoimidazole-4-carboxamide and F were evaluated by reversed-phase HPLC. For statistical calculations, groups were compared by the non-parametric Wilcoxon test. p<0.05 was considered statistically significant. No significant gender-dependent differences were observed in the pharmacokinetics of D and F. An additional response re-evaluation of 100 patients (50 female and 50 male) with glioblastoma multiforme, treated at our institution with D and F, gave no hint of any gender-dependent different response rates. We conclude that there is no evidence, neither from pharmacokinetic nor from our clinical data, to consider different dosages of D and F in female and male patients with glioblastoma multiforme.

There are several methodologies that can be used for evaluating patients' perception of their quality of life. Most commonly, utilities are directly elicited by means of either the time-trade-off or the standard-gamble method. In both methods, risk attitudes determine the quality of life values. Quality of life values among 31 Austrian undergraduate students were elicited by means of the standard gamble approach. The impact of several variables such as gender, side job, length of study, and living arrangements on the quality of life were identified using different types of regression techniques (ordinary least squares, generalized linear model, Betafit). Significant evidence was found that females are associated with a higher quality of life in all specifications of our estimations. The observed gender differences in quality of life can be attributed to a higher degree of risk aversion of women. A higher risk aversion leads to a higher valuation of given health states and a potential gender bias in health economic evaluations. This result could have implications for health policy planners when it comes to budget allocation decisions.

Besides the incidence of esophageal atresia (EA) being higher in males, no other gender-specific differences in EA have been reported. The aim of this study was to search for gender-specific differences in EA. A retrospective study was conducted at a tertiary center for pediatric surgery. The medical charts of infants born with EA were reviewed. 20 girls were identified, and 20 boys were selected as matched controls with respect to concomitant malformations. Their treatment and outcome were evaluated. Polyhydramnios was more common in pregnancies with boys, 40%, versus girls, 10%, with EA ( p < 0.01). In total, 36 (90%) children had patent ductus arteriosus, without any gender difference (18 and 18, resp., p =1). The distribution of days at the different levels of care was not equally distributed between boys and girls. Boys with EA had significantly more postoperative days (median 5 days) in the ward than girls (median 5 and 2 days, resp., p =0.04). No other gender-specific differences in surgical treatment, complications, or symptoms at follow-up were identified. Polyhydramnios appears to be more frequent in pregnancies with boys than girls with EA. In this study, boys have longer stays than girls at the pediatric surgery ward.

Gender-fair language consists of the symmetric linguistic treatment of women and men instead of using masculine forms as generics. In this study, we examine how the use of gender-fair language affects readers' support for social initiatives in Poland and Austria. While gender-fair language is relatively novel in Poland, it is well established in Austria. This difference may lead to different perceptions of gender-fair usage in these speech communities. Two studies conducted in Poland investigate whether the evaluation of social initiatives (Study 1: quotas for women on election lists; Study 2: support for women students or students from countries troubled by war) is affected by how female proponents (lawyers, psychologists, sociologists, and academics) are referred to, with masculine forms (traditional) or with feminine forms (modern, gender-fair). Study 3 replicates Study 2 in Austria. Our results indicate that in Poland, gender-fair language has negative connotations and therefore, detrimental effects particularly when used in gender-related contexts. Conversely, in Austria, where gender-fair language has been implemented and used for some time, there are no such negative effects. This pattern of results may inform the discussion about formal policies regulating the use of gender-fair language. PMID:26582996

The "gender gap" on various physics conceptual evaluations has been extensively studied. Men's average pretest scores on the Force Concept Inventory and Force and Motion Conceptual Evaluation are 13% higher than women's, and post-test scores are on average 12% higher than women's. This study analyzed the gender differences within the Conceptual Survey of Electricity and Magnetism (CSEM) in which the gender gap has been less well studied and is less consistent. In the current study, data collected from 1407 students (77% men, 23% women) in a calculus-based physics course over ten semesters showed that male students outperformed female students on the CSEM pretest (5%) and post-test (6%). Separate analyses were conducted for qualitative and quantitative problems on lab quizzes and course exams and showed that male students outperformed female students by 3% on qualitative quiz and exam problems. Male and female students performed equally on the quantitative course exam problems. The gender gaps within CSEM post-test scores, qualitative lab quiz scores, and qualitative exam scores were insignificant for students with a CSEM pretest score of 25% or less but grew as pretest scores increased. Structural equation modeling demonstrated that a latent variable, called Conceptual Physics Performance/Non-Quantitative (CPP/NonQnt), orthogonal to quantitative test performance was useful in explaining the differences observed in qualitative performance; this variable was most strongly related to CSEM post-test scores. The CPP/NonQnt of male students was 0.44 standard deviations higher than female students. The CSEM pretest measured CPP/NonQnt much less accurately for women (R2=4 % ) than for men (R2=17 % ). The failure to detect a gender gap for students scoring 25% or less on the pretest suggests that the CSEM instrument itself is not gender biased. The failure to find a performance difference in quantitative test performance while detecting a gap in qualitative performance suggests the qualitative differences do not result from psychological factors such as science anxiety or stereotype threat.

Ajayi, Emmanuel Olubusayo

2015-07-01

The aim of this study was to assess the normative and self-perceived need for orthodontic treatment in Nigerian children, and to evaluate distribution of orthodontic treatment need according to gender and age. The sample consisted of 441 randomly selected school children, aged 11-18 years in Benin City, Nigeria. The subjects were further sub-grouped according to gender (229 males and 212 females) and age (246 11-13 years old and 195 14-18 years old). The Dental health Component (DHC) and Aesthetic Component (AC) of Index of Orthodontic Treatment Need (IOTN) were used to assess orthodontic treatment need normatively. Self-perceived need was evaluated by asking the subjects to rate their dental aesthetics on the Aesthetic Component scale of IOTN. Chi-square tests were used to evaluate gender and age differences in distribution of treatment need. A definite need for orthodontic treatment was found among 21.5% (grades 4-5 of DHC) and 6.3% (grades 8-10 of AC) of the subjects; 3.9% of the subjects perceived a definite need for orthodontic treatment (grades 8-10 of AC). There were no statistically significant gender and age differences in distribution of orthodontic treatment need among the subjects (p > 0.05). The study revealed a need for orthodontic treatment in slightly more than one fifth (21.5%) of this sample of Nigerian children. The sample population has a lower need on aesthetic grounds and their normative and self-perceived orthodontic treatment needs were not influenced by gender and age.

As a result of new global priorities, there is a growing need for high-quality evaluations of gender-integrated health programmes. This systematic review examined 99 peer-reviewed articles on evaluations of gender-integrated (accommodating and transformative) health programmes with regard to their theory of change (ToC), study design, gender integration in data collection, analysis, and gender measures used. Half of the evaluations explicitly described a ToC or conceptual framework (n = 50) that guided strategies for their interventions. Over half (61%) of the evaluations used quantitative methods exclusively; 11% used qualitative methods exclusively; and 28% used mixed methods. Qualitative methods were not commonly detailed. Evaluations of transformative interventions were less likely than those of accommodating interventions to employ randomised control trials. Two-thirds of the reviewed evaluations reported including at least one specific gender-related outcome (n = 18 accommodating, n = 44 transformative). To strengthen evaluations of gender-integrated programmes, we recommend use of ToCs, explicitly including gender in the ToC, use of gender-sensitive measures, mixed-method designs, in-depth descriptions of qualitative methods, and attention to gender-related factors in data collection logistics. We also recommend further research to develop valid and reliable gender measures that are globally relevant.

Major gender differences exist in cardiovascular diseases and lead to different outcomes in women and men. However, attention and incorporation of sex-/gender-specific research might vary among disciplines. We therefore conducted a systematic review comparing publication characteristics and trends between stroke and myocardial infarction (MI) with respect to sex- and gender-related aspects. A systematic literature search was performed in PubMed to identify gender-/sex-related articles published for stroke and MI between 1977 and 2008. A specifically designed text mining program was used, and all literature was rated by two independent investigators. Publications were classified according to type of research performed, publication year, funding, geographical location, and gender of first and last authors. 962 articles were retrieved and limited to 405 (42%) gender-relevant publications; 131 on stroke and 274 on MI. Type of performed research differed, especially in disease management, which received little attention (17%) in stroke, while representing the major focus in MI (40%). In both areas, clinical presentation received little attention (3 and 5%). Although publications progressively increased in both fields, an 8- to 10-year time gap emerged for stroke compared to MI. Last authors in both areas were predominantly men, but female last authorship is increasing more significantly over time in the field of stroke. Research on sex and gender differences in MI and stroke is largely underfunded, particularly by the EU. The data demonstrate how sex-/gender-specific research differs between specialties, most likely due to the diverse interest, funding opportunities and authorship distributions identified.

Men and women have different needs, based on their gender or the socio-cultural construction. The government has issued a policy about accelerating the equivalence of gender since 2012 through responsive planning and budgeting. With the policy, every institution (including the institutions under the ministry of law and human rights) must integrate its gender perspective on planning and budgeting, then it can fulfill the different needs between men and women. One of the programs developed in prisons for prisoners is vocational education and technology for preparing the prisoners’ life after being released from the prison cells. This article was made for evaluating the vocational education and training given to the prisoners. Gender perspective is employed as the analyzing tool. The result was then used as the basis of formulating vocational education model integrating gender perspective. The research was conducted at the Prison of Demak Regency, Indonesia. The method used in the research is qualitative descriptive with data collection techniques using by in-depth interviews, observation and documentation. The data analysis uses statistic description of Harvard’s checklist category model and combined with Moser category model. The result shows that vocational education and training given have not considered the differences between men and women. As a result, the prisoners were still not able to understand their different needs which can cause gender injustice when they come into job market. It is suggested that gender perspective must be included as a teaching material in the vocational education and training.

Background Despite considerable research, relationships among gender, alcohol consumption, and health remain controversial, due to potential confounding by health-related attitudes and practices associated with drinking, measurement challenges, and marked gender differences in drinking. We examined gender/alcohol consumption differences in health-related attitudes and practices, and evaluated how these factors affected relationships among gender, alcohol consumption, and health status. Methods A stratified random sample of adult health-plan members completed a mail survey, yielding 7884 respondents (2995 male/4889 female). Using MANCOVAs and adjusting for health-related attitudes, values, and practices, we examined gender differences in relationships between alcohol consumption and health. Results More frequent heavy drinking was associated with worse health-related attitudes and values, worse feelings about visiting the doctor, and worse health-related practices. Relationships between health-related practices and alcohol use differed by gender, and daily or almost daily heavy drinking was associated with significantly lower physical and mental health for women compared to men. Drinking status (lifelong abstainers, former drinkers, and level of regular alcohol consumption) was related to health status and vitality, even after adjusting for health-related attitudes, values, and practices. Relationships did not differ by gender. Former drinkers reported lower physical and mental health status than either lifelong abstainers or current drinkers. Conclusions Drinking status is independently related to physical health, mental health, and vitality, even after controlling for the health-related attitudes, values, and practices expected to confound these relationships. Among current drinkers, women who engage in very frequent heavy drinking have worse physical and mental health than their male counterparts. PMID:23946720

The prevalence of HIV/AIDS infection among prisoners is 3 to 4 times higher than in the U.S. population. Given that one in seven HIV-positive Americans pass through a correctional facility every year, the criminal justice system is in an ideal position to aggressively implement effective HIV education, treatment, and prevention. This study examines barriers to the effective delivery of these services and evaluates differences in risk perception among nearly 600 female and male inmates. The results underscore gender differences in Perceived Risk of Seroconversion and Exposure to HIV Education, suggesting that jails should implement gender-specific HIV prevention programming.

Three studies (N = 990) assessed the statistical reliability of two methods of determining gender identity that can capture transgender spectrum identities (i.e., current gender identities different from birth-assigned gender categories). Study 1 evaluated a single question with four response options (female, male, transgender, other) on university students. The missing data rate was higher than the valid response rates for transgender and other options using this method. Study 2 evaluated a method of asking two separate questions (i.e., one for current identity and another for birth-assigned category), with response options specific to each. Results showed no missing data and two times the transgender spectrum response rate compared to Study 1. Study 3 showed that the two-question method also worked in community samples, producing near-zero missing data. The two-question method also identified cisgender identities (same birth-assigned and current gender identity), making it a dynamic and desirable measurement tool for the social and medical sciences.
Gender gap on concept inventories in physics: What is consistent, what is inconsistent, and what factors influence the gap?

We review the literature on the gender gap on concept inventories in physics. Across studies of the most commonly used mechanics concept inventories, the Force Concept Inventory and Force and Motion Conceptual Evaluation, men’s average pretest scores are always higher than women’s, and in most cases men’s posttest scores are higher as well. The weighted average gender difference on these tests is 13% for pretest scores, 12% for posttest scores, and 6% for normalized gain. This difference is much smaller than the average difference in normalized gain between traditional lecture and interactive engagement (25%), but it is large enough that it could impact the results of studies comparing the effectiveness of different teaching methods. There is sometimes a gender gap on commonly used electricity and magnetism concept inventories, the Brief Electricity and Magnetism Assessment and Conceptual Survey of Electricity and Magnetism, but it is usually much smaller and sometimes is zero or favors women. The weighted average gender difference on these tests is 3.7% for pretest scores, 8.5% for posttest scores, and 6% for normalized gain. There are far fewer studies of the gender gap on electricity and magnetism concept inventories and much more variation in the existing studies. Based on our analysis of 26 published articles comparing the impact of 30 factors that could potentially influence the gender gap, no single factor is sufficient to explain the gap. Several high-profile studies that have claimed to account for or reduce the gender gap have failed to be replicated in subsequent studies, suggesting that isolated claims of explanations of the gender gap should be interpreted with caution. For example, claims that the gender gap could be eliminated through interactive engagement teaching methods or through a “values affirmation writing exercise” were not supported by subsequent studies. Suggestions that the gender gap might be reduced by changing the wording of “male-oriented” questions or refraining from asking demographic questions before administering the test are not supported by the evidence. Other factors, such as gender differences in background preparation, scores on different kinds of assessment, and splits between how students respond to test questions when answering for themselves or for a “scientist” do contribute to a difference between male and female responses, but the size of these differences is smaller than the size of the overall gender gap, suggesting that the gender gap is most likely due to the combination of many small factors rather than any one factor that can easily be modified.
Trends in child immunization across geographical regions in India: focus on urban-rural and gender differentials.

Although child immunization is regarded as a highly cost-effective lifesaver, about fifty percent of the eligible children aged 12-23 months in India are without essential immunization coverage. Despite several programmatic initiatives, urban-rural and gender difference in child immunization pose an intimidating challenge to India's public health agenda. This study assesses the urban-rural and gender difference in child immunization coverage during 1992-2006 across six major geographical regions in India. Three rounds of the National Family Health Survey (NFHS) conducted during 1992-93, 1998-99 and 2005-06 were analyzed. Bivariate analyses, urban-rural and gender inequality ratios, and the multivariate-pooled logistic regression model were applied to examine the trends and patterns of inequalities over time. The analysis of change over one and half decades (1992-2006) shows considerable variations in child immunization coverage across six geographical regions in India. Despite a decline in urban-rural and gender differences over time, children residing in rural areas and girls remained disadvantaged. Moreover, northeast, west and south regions, which had the lowest gender inequality in 1992 observed an increase in gender difference over time. Similarly, urban-rural inequality increased in the west region during 1992-2006. This study suggests periodic evaluation of the health care system is vital to assess the between and within group difference beyond average improvement. It is essential to integrate strong immunization systems with broad health systems and coordinate with other primary health care delivery programs to augment immunization coverage.

To explore quantitative differences between genders in morphologic colonic metrics and determine metric reproducibility. Quantitative colonic metrics from 20 male and 20 female CTC datasets were evaluated twice by two readers; all exams were performed after incomplete optical colonoscopy. Intra-/inter-reader reliability was measured with intraclass correlation coefficient (ICC) and concordance correlation coefficient (CCC). Women had overall decreased colonic volume, increased tortuosity and compactness and lower sigmoid apex height on CTC compared to men (p<0.0001,all). Quantitative measurements in colonic metrics were highly reproducible (ICC=0.9989 and 0.9970; CCC=0.9945). Quantitative morphologic differences between genders can be reproducibility measured.

There is increasing recognition of sex/gender differences in health and the importance of identifying differential effects of interventions for men and women. Yet, to whom the research evidence does or does not apply, with regard to sex/gender, is often insufficiently answered. This is also true for systematic reviews which synthesize results of primary studies. A lack of analysis and reporting of evidence on sex/gender raises concerns about the applicability of systematic reviews. To bridge this gap, this pilot study aimed to translate knowledge about sex/gender analysis (SGA) into a user-friendly 'briefing note' format and evaluate its potential in aiding the implementation of SGA in systematic reviews. Our Sex/Gender Methods Group used an interactive process to translate knowledge about sex/gender into briefing notes, a concise communication tool used by policy and decision makers. The briefing notes were developed in collaboration with three Cochrane Collaboration review groups (HIV/AIDS, Hypertension, and Musculoskeletal) who were also the target knowledge users of the briefing notes. Briefing note development was informed by existing systematic review checklists, literature on sex/gender, in-person and virtual meetings, and consultation with topic experts. Finally, we held a workshop for potential users to evaluate the notes. Each briefing note provides tailored guidance on considering sex/gender to reviewers who are planning or conducting systematic reviews and includes the rationale for considering sex/gender, with examples specific to each review group's focus. Review authors found that the briefing notes provided welcome guidance on implementing SGA that was clear and concise, but also identified conceptual and implementation challenges. Sex/gender briefing notes are a promising knowledge translation tool. By encouraging sex/gender analysis and equity considerations in systematic reviews, the briefing notes can assist systematic reviewers in ensuring the applicability of research evidence, with the goal of improved health outcomes for diverse populations.
Effects of Gender and Personality on First Impression

The present study explores whether and to what extent individual differences (i.e., gender and personality traits of perceiver) predict inferences of trustworthiness from emotionally neutral unfamiliar faces and the related confidence in judgment. Four hundred and ten undergraduate students participated in the study. Personality was assessed using the Big Five model (i.e., Extraversion, Neuroticism, Conscientiousness, Agreeableness and Openness to experience) and measures of trait anxiety and aggression. The results suggest that trustworthiness judgments are affected by the gender of the perceiver, although this effect depends on the valence of the face. Women tend to judge trustworthy-looking faces as significantly more trustworthy than men do, and this is particularly pronounced for judgments of female faces. There were no gender differences for judgments of untrustworthy-looking or neutral faces. Gender also seems to affect the confidence in judgment. Specifically, women were generally less confident than men in judging trustworthiness of unfamiliar faces. Personality also affected judgment. Both low agreeable individuals and high trait aggressive individuals tend to perceive unfamiliar faces as less trustworthy. The present findings suggest that both gender and personality traits are relevant for understanding how people evaluate the trustworthiness of others. Whom we decide to trust is a function not only of their facial features but also of gender and individual differences in personality traits. PMID:26331610

Acute inhalation toxicity of chemicals has conventionally been assessed by the median lethal concentration (LC50) test (organisation for economic co-operation and development (OECD) TG 403). Two new methods, the recently adopted acute toxic class method (ATC; OECD TG 436) and a proposed fixed concentration procedure (FCP), have recently been considered, but statistical evaluations of these methods did not investigate the influence of differential sensitivity between male and female rats on the outcomes. This paper presents an analysis of data from the assessment of acute inhalation toxicity for 56 substances. Statistically significant differences between the LC50 for males and females were found for 16 substances, with greater than 10-fold differences in the LC50 for two substances. The paper also reports a statistical evaluation of the three test methods in the presence of unanticipated gender differences. With TG 403, a gender difference leads to a slightly greater chance of under-classification. This is also the case for the ATC method, but more pronounced than for TG 403, with misclassification of nearly all substances from Globally Harmonised System (GHS) class 3 into class 4. As the FCP uses females only, if females are more sensitive, the classification is unchanged. If males are more sensitive, the procedure may lead to under-classification. Additional research on modification of the FCP is thus proposed. PMID:20488841

Evaluating the effects of heart cavity volume, presence and absence of perfusion defect, gender and type of study (stress and rest) on the difference of systolic parameters of myocardial perfusion scan in 16 and 8 framing gated SPECT imaging. Cardiac gated SPECT in both 16 and 8 framing simultaneously and both stress and rest phases at one-day protocol was performed for 50 patients. Data have been reconstructed by filter back projection (FBP) method and left ventricular (LV) systolic parameters were calculated by using QGS software. The effect of some factors such as LV cavity volume, presence and absence of perfusion defect, gender and type of study on data difference between 8 and 16 frames were evaluated. The differences in ejection fraction (EF), end-diastolic volume (EDV) and end-systolic volume (ESV) in both stress and rest were statistically significant. Difference in both framing was more in stress for EF and ESV, and was more in rest for EDV. Study type had a significant effect on differences in systolic parameters while gender had a significant effect on differences in EF and ESV in rest between both framings. In conclusion, results of this study revealed that difference of both 16 and 8 frames data in systolic phase were statistically significant and it seems that because of better efficiency of 16 frames, it cannot be replaced by 8 frames. Further well-designed studies are required to verify these findings.

To evaluate ascending aortic strain (AAS) with cardiac magnetic resonance (CMR) in a large consecutive series of patients with different types of cardiovascular disease (CVD). Two-dimensional phase-contrast gradient-echo sequences of the ascending aorta were retrospectively reviewed in 1027 patients (726 males, 301 females). Aortic lumen area was segmented using a semi-automatic approach to calculate AAS values. Subgroup analysis was performed for patients with normal CMR, tetralogy of Fallot (ToF), and ischemic heart disease (IHD). Multivariate and post-hoc analyses were performed to evaluate the effect of age, gender, and CVD on AAS values. Shapiro-Wilk, three- and two-way ANOVA, Mann-Whitney U, and Spearman correlation statistics were used. Multivariate analysis showed significant differences in AAS among decades of age (p<0.001), genders (p=0.006) and CVD subgroups (p<0.001) without interaction among these factors. A gender-related difference (higher AAS in females) was significant in ToF (p=0.008), while an AAS reduction during aging was observed in all CVD subgroups. Post-hoc analysis showed a significantly lower AAS in ToF and IHD patients compared to subjects with normal CMR (p<0.001). Differences in age, gender, and CVD independently affect AAS. The lower AAS observed in ToF fosters its assessment during follow-up in adulthood. Future studies on causes and clinical implications of a higher AAS in females affected by ToF are warranted.

Research on gender differences in perceptions of sexual harassment informs an ongoing legal debate regarding the use of a reasonable person standard instead of a reasonable woman standard to evaluate sexual harassment claims. The authors report a meta-analysis of 62 studies of gender differences in harassment perceptions. An earlier quantitative review combined all types of social-sexual behaviors for a single meta-analysis; the purpose of this study was to investigate whether the magnitude of the female-male difference varies by type of behavior. An overall standardized mean difference of 0.30 was found, suggesting that women perceive a broader range of social-sexual behaviors as harassing. However, the meta-analysis also found that the female-male difference was larger for behaviors that involve hostile work environment harassment, derogatory attitudes toward women, dating pressure, or physical sexual contact than sexual propositions or sexual coercion.

The study used behavioral health service claims (2008-2013) from Optum to estimate gender-stratified penetration rates of behavioral health service use by couple type and partnership status among partnered adults ages 18-64 (N=12,727,292 person-years) and levels of use among those with any use (conditional analyses). Least-squares, logistic, and zero-truncated negative binomial regression analyses adjusted for age, employer and plan characteristics, and provider supply and for sociodemographic factors in sensitivity analyses. Generalized estimating equations were used to address within-group correlation of adults clustered in employer groups. Both women and men in same-gender marriages or domestic partnerships had higher rates of behavioral health service use, particularly diagnostic evaluation, individual psychotherapy, and medication management, and those in treatment had, on average, more psychotherapy visits than those in different-gender marriages. Behavioral health treatment patterns were similar between women in same-gender domestic partnerships and same-gender marriages, but they diverged between men in same-gender domestic partnerships and same-gender marriages. Moderation analysis results indicated that adults with same-gender partners living in states with fewer legal protections for lesbian, gay, bisexual, and transgender persons were less likely than adults with same-gender partners in LGBT-friendly states to receive behavioral health treatment. Sensitivity analyses did not affect findings. Behavioral health treatment patterns varied by couple type, partnership status, and gender. Results highlight the importance of increasing service acceptability and delivering inclusive, culturally relevant behavioral health treatment for lesbian, gay, and bisexual persons.

This article examines whether there are gender differences in understanding the emotions evaluated by the Test of Emotion Comprehension (TEC). The TEC provides a global index of emotion comprehension in children 3-11 years of age, which is the sum of the nine components that constitute emotion comprehension: (1) recognition of facial expressions, (2) understanding of external causes of emotions, (3) understanding of desire-based emotions, (4) understanding of belief-based emotions, (5) understanding of the influence of a reminder on present emotional states, (6) understanding of the possibility to regulate emotional states, (7) understanding of the possibility of hiding emotional states, (8) understanding of mixed emotions, and (9) understanding of moral emotions. We used the answers to the TEC given by 172 English girls and 181 boys from 3 to 8 years of age. First, the nine components into which the TEC is subdivided were analysed for differential item functioning (DIF), taking gender as the grouping variable. To evaluate DIF, the Mantel-Haenszel method and logistic regression analysis were used applying the Educational Testing Service DIF classification criteria. The results show that the TEC did not display gender DIF. Second, when absence of DIF had been corroborated, it was analysed for differences between boys and girls in the total TEC score and its components controlling for age. Our data are compatible with the hypothesis of independence between gender and level of comprehension in 8 of the 9 components of the TEC. Several hypotheses are discussed that could explain the differences found between boys and girls in the belief component. Given that the Belief component is basically a false belief task, the differences found seem to support findings in the literature indicating that girls perform better on this task.

Importance Although implicit bias in medical training has long been suspected, it has been difficult to study using objective measures, and the influence of sex and gender in the evaluation of medical trainees is unknown. The emergency medicine (EM) milestones provide a standardized framework for longitudinal resident assessment, allowing for analysis of resident performance across all years and programs at a scope and level of detail never previously possible. Objective To compare faculty-observed training milestone attainment of male vs female residency training Design, Setting, and Participants This multicenter, longitudinal, retrospective cohort study took place at 8 community and academic EM training programs across the United States from July 1, 2013, to July 1, 2015, using a real-time, mobile-based, direct-observation evaluation tool. The study examined 33 456 direct-observation subcompetency evaluations of 359 EM residents by 285 faculty members. Main Outcomes and Measures Milestone attainment for male and female EM residents as observed by male and female faculty throughout residency and analyzed using multilevel mixed-effects linear regression modeling. Results A total of 33 456 direct-observation evaluations were collected from 359 EM residents (237 men [66.0%] and 122 women [34.0%]) by 285 faculty members (194 men [68.1%] and 91 women [31.9%]) during the study period. Female and male residents achieved similar milestone levels during the first year of residency. However, the rate of milestone attainment was 12.7% (0.07 levels per year) higher for male residents through all of residency (95% CI, 0.04-0.09). By graduation, men scored approximately 0.15 milestone levels higher than women, which is equivalent to 3 to 4 months of additional training, given that the average resident gains approximately 0.52 levels per year using our model (95% CI, 0.49-0.54). No statistically significant differences in scores were found based on faculty evaluator gender (effect size difference, 0.02 milestone levels; 95% CI for males, −0.09 to 0.11) or evaluator-evaluatee gender pairing (effect size difference, −0.02 milestone levels; 95% CI for interaction, −0.05 to 0.01). Conclusions and Relevance Although male and female residents receive similar evaluations at the beginning of residency, the rate of milestone attainment throughout training was higher for male than female residents across all EM subcompetencies, leading to a gender gap in evaluations that continues until graduation. Faculty should be cognizant of possible gender bias when evaluating medical trainees. PMID:28264090
Gender differences in the disposition and toxicity of metals

Vahter, Marie; Akesson, Agneta; Liden, Carola

There is increasing evidence that health effects of toxic metals differ in prevalence or are manifested differently in men and women. However, the database is small. The present work aims at evaluating gender differences in the health effects of cadmium, nickel, lead, mercury and arsenic. There is a markedly higher prevalence of nickel-induced allergy and hand eczema in women compared to men, mainly due to differences in exposure. Cadmium retention is generally higher in women than in men, and the severe cadmium-induced Itai-itai disease was mainly a woman's disease. Gender differences in susceptibility at lower exposure are uncertain, but recentmore » data indicate that cadmium has estrogenic effects and affect female offspring. Men generally have higher blood lead levels than women. Lead accumulates in bone and increased endogenous lead exposure has been demonstrated during periods of increased bone turnover, particularly in women in pregnancy and menopause. Lead and mercury, in the form of mercury vapor and methylmercury, are easily transferred from the pregnant women to the fetus. Recent data indicate that boys are more susceptible to neurotoxic effects of lead and methylmercury following exposure early in life, while experimental data suggest that females are more susceptible to immunotoxic effects of lead. Certain gender differences in the biotransformation of arsenic by methylation have been reported, and men seem to be more affected by arsenic-related skin effect than women. Experimental studies indicate major gender differences in arsenic-induced cancer. Obviously, research on gender-related differences in health effects caused by metals needs considerable more focus in the future.« less

Introduction There are large differences in the burden and health implications of obesity by race and gender in the US. It is unclear to what extent policies modifying caloric consumption change the distribution of the burden of obesity and related health outcomes. Meat is a large component of the American diet. We investigate how changing meat prices (that may result from policies or from exogenous factors that reduce supply) might impact the burden of obesity by race and gender. Methods We construct a microsimulation model that evaluates the 15-year body-mass index (BMI) and mortality impact of changes in meat price (5, 10, 25, and 50% increase) in the US adult population stratified by age, gender, race, and BMI. Results Under each price change evaluated, relative to the status quo, white males, black males, and black females are expected to realize more dramatic reduction in 2030 obesity prevalence than white females. Life expectancy gains are also projected to differ by subpopulation, with black males far less likely to benefit from an increase in meat prices than other groups. Conclusions Changing meat prices has considerable potential to affect population health differently by race and gender. In designing interventions that alter the price of foods to consumers, it is not sufficient to assess health effects based solely on the population as a whole, since differential effects across subpopulations may be substantial.

[About the heterogeneity in adolescents with gender identity disorder: differential importance of psychiatric comorbidity and considerations of individual psychodynamics].

2014-01-01

Gender identity disorder (GID), gender dysphoria (GD) respectively, is considered a multifactorial disease whose etiology is subject to complex bio-psycho-social conditions, each with different weighting. As a result, therapists, who treat children and adolescents with GID/GD, have to deal with a very heterogeneous group with individually varying causes, differing psychopathology and varying disease progression. In addition to general psychiatric aspects of development, particularly psychiatric comorbidity, but also the different individual psychodynamics--i. e. the specific constellation of conflicts and possible ego deficits and structural deficits in the learning history of the person are of differential importance. In regard to the indication for gender reassignment measures this sometimes is relevant for the decision. The difficulties arising for decision making and the usefulness of a systematic evaluation of case reports as a basis for further optimization of the treatment recommendations are illustrated by two case reports. In the course of this, also the disadvantages and potential dangers of too early diagnostic definition and introduction of gender somato-medical and legal measures are shown exemplarily.

To identify gender differences in social support dimensions' effect on adults' leisure-time physical activity maintenance, type, and time. Longitudinal study of 1,278 non-faculty public employees at a university in Rio de Janeiro, RJ, Southeastern Brazil. Physical activity was evaluated using a dichotomous question with a two-week reference period, and further questions concerning leisure-time physical activity type (individual or group) and time spent on the activity. Social support was measured with the Medical Outcomes Study Social Support Scale. For the analysis, logistic regression models were adjusted separately by gender. A multinomial logistic regression showed an association between material support and individual activities among women (OR = 2.76; 95%CI 1.2;6.5). Affective support was associated with time spent on leisure-time physical activity only among men (OR = 1.80; 95%CI 1.1;3.2). All dimensions of social support that were examined influenced either the type of, or the time spent on, leisure-time physical activity. In some social support dimensions, the associations detected varied by gender. Future studies should attempt to elucidate the mechanisms involved in these gender differences.

Studies have shown pharmacokinetic differences for hypnotics in women compared to men, but few studies have assessed either short-or long-term differences in efficacy and safety. To evaluate gender differences in the efficacy and safety of chronic nightly zolpidem (10 mg), we did a post hoc assessment of a large clinical trial. In the trial, participants with primary insomnia (n = 89), ages 23-70, meeting DSM-IV-TR criteria for primary insomnia were randomized, double blind, to nightly zolpidem, 10 mg (n = 47) or placebo (n = 42) 30 minutes before bedtime nightly for 12 months. Polysomnographic sleep on 2 nights in months 1 and 8 and likelihood of next-day sleepiness, rebound insomnia, and dose escalation were evaluated in months 1, 4, and 12. Relative to placebo, zolpidem significantly increased sleep efficiency and reduced sleep latency and wake after sleep onset assessed at months 1 and 8, with no differences in efficacy between women and men and no diminution of efficacy over months. On a next-day multiple sleep latency test (MSLT), no residual sedation was observed for either women or men. No rebound insomnia or dose escalation was seen with no gender differences in either. In adults with primary insomnia, nightly zolpidem administration showed no gender differences in acute or chronic efficacy or in next-day sleepiness. Zolpidem remained efficacious and safe across 12 months.

In order to provide science-based guidelines for injury prevention or return to play, regular measurement of isometric and eccentric internal (IR) and external (ER) rotator strength is warranted in overhead athletes. However, up to date, no normative database exists regarding these values, when measured with a hand-held dynamometer. Therefore, the purpose of the study was to provide a normative database on isometric and eccentric rotator cuff (RC) strength values in a sample of overhead athletes, and to discuss gender, age and sports differences. A HHD was used to measure RC strength in 201 overhead athletes between 18 and 50 years old from three different sports disciplines: tennis, volleyball and handball. Isometric as well as eccentric strength was measured in different shoulder positions. Outcome variables of interest were isometric ER and IR strength, eccentric ER strength, and intermuscular strength ratios ER/IR. Our results show significant side, gender and sports discipline differences in the isometric and eccentric RC strength. However, when normalized to body weight, gender differences often are absent. In general, strength differences are in favour of the dominant side, the male athletes and handball. Intermuscular ER/IR ratios showed gender, sports, and side differences. This normative database is necessary to help the clinician in the evaluation of RC strength in healthy and injured overhead athletes. In view of the preventive screening and return-to-play decisions in overhead athletes, normalization to body weight and calculating intermuscular ratios are key points in this evaluation.

(i) gender; (ii) performance and; (iii) gender versus performance interactions in young swimmers' anthropometric, kinematic and energetic variables. One hundred and thirty six young swimmers (62 boys: 12.76 ± 0.72 years old at Tanner stages 1-2 by self-evaluation; and 64 girls: 11.89 ± 0.93 years old at Tanner stages 1-2 by self-evaluation) were evaluated. Performance, anthropometrics, kinematics and energetic variables were selected. There was a non-significant gender effect on performance, body mass, height, arm span, trunk transverse surface area, stroke length, speed fluctuation, swimming velocity, propulsive efficiency, stroke index and critical velocity. A significant gender effect was found for foot surface area, hand surface area and stroke frequency. A significant sports level effect was verified for all variables, except for stroke frequency, speed fluctuation and propulsive efficiency. Overall, swimmers in quartile 1 (the ones with highest sports level) had higher anthropometric dimensions, better stroke mechanics and energetics. These traits decrease consistently throughout following quartiles up to the fourth one (i.e. swimmers with the lowest sports level). There was a non-significant interaction between gender and sports level for all variables. Our main conclusions were as follows: (i) there are non-significant differences in performance, anthropometrics, kinematics and energetics between boys and girls; (ii) swimmers with best performance are taller, have higher surface areas and better stroke mechanics; (iii) there are non-significant interactions between sports level and gender for anthropometrics, kinematics and energetics.

Hurricane Sandy was a natural disaster of large proportions--a category 3 storm at its peak intensity that struck New York Metropolitan Area on October, 2012. The death and destruction caused by a hurricane can rise numerous of mental health vulnerabilities such as, acute stress disorder, posttraumatic stress disorder, depression, and anxiety. Gender has been identified as one critical variable that can impact vulnerability to adverse effects of trauma, as well as how these reactions are managed. The present research provides an evaluation of gender differences regarding posttraumatic stress symptoms, recollections of national disasters and fears of future negative life events. It also aims to explore information seeking and sources of assistance that were utilized during Hurricane Sandy. An online survey sample of 1,000 people from New York Metropolitan Area completed a battery of self-report questionnaires four weeks after the storm. Results revealed that recollections of national disaster and fear of future events were found to be significantly different among women compared to men. Additionally, women were more inclined toward information seeking through Facebook than men, although no gender differences emerged when examining sources of support. The results indicate that disaster practitioners should tailor gender sensitive interventions.

Investigations of patterns of sexual arousal to certain groups of sexually explicit media (SEM) in the general population in non-laboratory settings are rare. Such knowledge could be important to understand more about the relative specificity of sexual arousal in different SEM users. (i) To investigate whether sexual arousal to non-mainstream vs mainstream SEM contents could be categorized across gender and sexual orientation, (ii) to compare levels of SEM-induced sexual arousal, sexual satisfaction, and self-evaluated sexual interests and fantasies between non-mainstream and mainstream SEM groups, and (iii) to explore the validity and predictive accuracy of the Non-Mainstream Pornography Arousal Scale (NPAS). Online cross-sectional survey of 2,035 regular SEM users in Croatia. Patterns of sexual arousal to 27 different SEM themes, sexual satisfaction, and self-evaluations of sexual interests and sexual fantasies. Groups characterized by sexual arousal to non-mainstream SEM could be identified across gender and sexual orientation. These non-mainstream SEM groups reported more SEM use and higher average levels of sexual arousal across the 27 SEM themes assessed compared with mainstream SEM groups. Only few differences were found between non-mainstream and mainstream SEM groups in self-evaluative judgements of sexual interests, sexual fantasies, and sexual satisfaction. The internal validity and predictive accuracy of the NPAS was good across most user groups investigated. The findings suggest that in classified non-mainstream SEM groups, patterns of sexual arousal might be less fixated and category specific than previously assumed. Further, these groups are not more judgmental of their SEM-related sexual arousal patterns than groups characterized by patterns of sexual arousal to more mainstream SEM content. Moreover, accurate identification of non-mainstream SEM group membership is generally possible across gender and sexual orientation using the NPAS. Hald GM, Stulhofer A, Lange T, et al.

BACKGROUND: In a cross-sectional study examining late effects of pediatric sarcoma therapy, long-term survivors were evaluated on their activities of daily living (ADL) performance. PROCEDURE: Thirty-two persons with Ewing sarcoma family of tumors, rhabdomyosarcoma, and non-rhabdomysarcoma-soft tissue sarcoma enrolled an average of 17 years after treatment. Participants were evaluated using the Assessment of Motor and Process Skills (AMPS) [1], a standardized observational evaluation of ADL task performance. Means and 95% confidence intervals for ADL motor and ADL process ability measures were calculated for four groups: 1) sarcoma survivors, 2) “well” adults matched for age and gender, 3) “well” adults matched for gender that were 10 years older; and 4) “well” adults matched for gender that were 20 years older. RESULTS: ADL motor ability was significantly lower for sarcoma survivors than for the age and gender matched comparison group (p<0.05). There was no significant difference between ADL motor ability of sarcoma survivors and the comparison group 10 years older, but sarcoma survivors had significantly better ADL motor ability (p<0.05) than the oldest comparison group (20 years older). Sarcoma survivors had significantly worse ADL process ability than the age matched group (p<0.05). There was no difference in ADL process ability between the sarcoma survivors and comparison groups that were 10 and 20 years older. CONCLUSIONS: This first report of a clinical evaluation of ADL limitation in pediatric sarcoma survivors treated with intensive multimodal cancer therapy suggests that influences on performance of daily life activities are more common than previously reported.

Diet and health behaviors and perceptions of adult urban Native American Indians in a large Midwestern city were evaluated for differences by tribal association, gender, and age grouping. The hypothesis was that human behavior is influenced by tribal association, gender, and age grouping in the subject population. The subjects included 33 men and 32 women, with 26 being Sioux; 22 Omaha; and 17 a combination of other tribes. The descriptive survey included two interviewer-administered 24-hour recalls. The majority of subjects were overweight or obese. Significant differences (P< .05) were observed in vitamin A and calcium intakes by tribal association. Men reported consuming significantly more (P< .05) kilocalories, vitamin C, and sodium. Over half the subjects consumed more than the recommended 20% to 35% kcal from fat, >or=10% kcal from saturated fat, and >or=300 mg cholesterol/d. Less than Estimated Average Requirements for vitamin A, vitamin C, and iron were consumed by 31%, 59%, and 6%, respectively; 79% consumed less than Adequate Intakes for calcium. Ninety-two percent consumed more than the Tolerable Upper Intake Level for sodium. Few differences were observed in the kilocalorie, vitamin A, vitamin C, calcium, and sodium intakes of these Native American Indians by tribal association, gender, or age grouping. Significant differences in percentages consuming alcohol were observed by gender (P< .05) and by age grouping (P< .01). A significant difference (P< .01) was observed by gender regarding the subjects' perceptions of their being alcoholics. Overall, few differences were observed in diet and health behaviors and perceptions of adult urban Native American Indians by tribal association, gender, and age grouping.

Inequalities between men and women are common and well-documented. Objective indexes show that men are better positioned than women in societal hierarchies-there is no single country in the world without a gender gap. In contrast, researchers have found that the women-are-wonderful effect-that women are evaluated more positively than men overall-is also common. Cross-cultural studies on gender equality reveal that the more gender egalitarian the society is, the less prevalent explicit gender stereotypes are. Yet, because self-reported gender stereotypes may differ from implicit attitudes towards each gender, we reanalysed data collected across 44 cultures, and (a) confirmed that societal gender egalitarianism reduces the women-are-wonderful effect when it is measured more implicitly (i.e. rating the personality of men and women presented in images) and (b) documented that the social perception of men benefits more from gender egalitarianism than that of women. © 2017 International Union of Psychological Science.

Summary There are likely to be gender differences in determinants of relapse to drug use following abstinence in cocaine-dependent individuals. Cocaine-dependent women are more likely to attribute relapse to negative emotional states and interpersonal conflict. Cocaine dependence has also been linked to dysregulation of stress response and the hypothalamic pituitary adrenal (HPA) axis which may differ between genders. Subjective and HPA axis responses to a social evaluative stressor, the Trier Social Stress Test (TRIER), and in vivo cocaine-related cues were examined in the present study. Results There were no gender differences in magnitude of craving responses to the TRIER or the CUE. Both genders had a greater craving response to the CUE than to the TRIER, but the magnitude of the difference was greater for men than women (p=0.04). Cocaine-dependent subjects, compared to the control group, had significantly higher response throughout the TRIER (p<0.0001) and CUE (p<0.0001) testing sessions. There were no gender differences and no gender by cocaine interaction for ACTH responses to the TRIER, although women had lower baseline ACTH (p=0.049). On the CUE task, in contrast, female cocaine-dependent subjects had a more blunted ACTH response than did the other three groups (p=0.02). Female cocaine-dependent subjects also had a lower odds of a positive cortisol response to the TRIER as compared to the other three groups (OR=0.84, 95% CI=[0.02, 1.01]). During the CUE task, cocaine-dependent subjects had overall higher mean cortisol levels (p=0.0001), and higher odds of demonstrating a positive cortisol response to the CUE (OR=2.61, 95% CI=[1.11, 6.11]). No gender differences were found in ACTH responses to the CUE. The results are reviewed in the context of the existing literature on gender differences in cocaine dependence and potential implications for treatment are discussed. PMID:20004523

Work capacity is related to physical, environmental and psychosocial factors and is influenced by individual characteristics and occupations. The aim of this study was to evaluated the relationship between work capacity, gender and age. 360 people employed at an institution of higher education of both genders and similar age were asked to participate in this study. The ability to work was analyzed using Work Ability Index (WAI). Descriptive statistical, Pearson correlations and ANOVA test was applied. Of these, 197 workers who participated in the study completed and returned the questionnaire. The results show there weren't any significant differences between work ability in relation to gender and age, but we observed an increase variability of responses for WAI score in older workers. No significant differences in the perception of the ability of work between men and women..

Prior studies have shown a relationship between female gender and adverse outcomes after percutaneous coronary interventions (PCIs). Whether this relationship still exists with contemporary PCI remains to be determined. We evaluated gender differences in clinical outcomes in a large registry of contemporary PCI. Data were prospectively collected from 22,725 consecutive PCIs in a multicenter regional consortium (Blue Cross Blue Shield of Michigan Cardiovascular Consortium) between January 2002 and December 2003. The primary end point was in-hospital all-cause mortality; other clinical outcomes evaluated included in-hospital death, vascular complications, transfusion, postprocedure myocardial infarction, stroke, and a combined major cardiovascular adverse event (MACE) end point including myocardial infarction, death, stroke, emergency coronary artery bypass grafting, and repeated PCI at the same site. Independent predictors of adverse outcomes were identified using multivariate logistic regression analysis. Compared with men, women were older, had a higher prevalence of comorbidities, and had a significantly higher frequency of adverse outcomes after PCI. After adjustment for baseline demographics, comorbidities, clinical presentation, and lesion characteristics, female gender was associated with an increased risk of in-hospital death, vascular complication, blood transfusion, stroke, and MACE. The relationship between female gender and increased risk of death and MACE was no longer present after further adjustment for kidney function and low body surface area. Differences in mortality rates between men and women no longer exist after PCI. However, our data suggest that technological advancements have not completely offset the relationship between gender and adverse outcomes after PCI. Copyright 2010 Mosby, Inc. All rights reserved.
The study of athletes' body perception and gender role.

PubMed

Bastug, Gulsum

In this study, it has been aimed to examine athletes' body perception and gender role. 120 male athletes and 120 non-athletic male university students participated in the study voluntarily. In the study, as the data collecting means, The Multidimensional Body-Self Relations Questionnaire-MBSRQ was used in order to determine males' body perception levels, BEM Sex Role Inventory-BSRI was used to determine gender roles and Personal Information Form developed by the researcher was used to ascertain personal features of the subjects. When the athletes' body perception levels are examined, the features of physical competence orientation, health orientation, appearance evaluation, fitness evaluation, health evaluation and body areas satisfaction have been found to be higher than non-athletes' (p < 0.05). On the other hand; no difference has been found between athletes and non-athletes in terms of appearance orientation (p > 0.05). When gender roles are examined, athletes have been found to have higher values than non-athletes' in terms of masculinity, femininity and social desirability (p < 0.05). To conclude; as well as considering sports as a factor increasing individuals' body perception level and gender role, it is also thought that athletes care about health, appearance and physical competence and are glad of body parts because of their muscled body structure developing due to the exercises and have flexible personality to show feminine and masculine features that the environment needs in terms of gender role.
Families, resources, and adult health: where do sexual minorities fit?

Extensive research documents the relevance of families and socioeconomic resources to health. This article extends that research to sexual minorities, using 12 years of the National Health Interview Survey (N = 460,459) to examine self-evaluations of health among male and female adults living in same-sex and different-sex relationships. Adjusting for socioeconomic status eliminates differences between same- and different-sex cohabitors so that they have similarly higher odds of poor health relative to married persons. Results by gender reveal that the cohabitation disadvantage for health is more pronounced for different-sex cohabiting women than for men, but little difference exists between same-sex cohabiting men and women. Finally, the presence of children in the home is more protective for women's than men's health, but those protections are specific to married women. In all, the results elucidate the importance of relationship type, gender, and the presence of children when evaluating health.
Incorporating a gender perspective into sexual health promotion.

PubMed

Gordon, G

1995-01-01

The roles of men and women affect sexual health and often make it difficult for either sex to adopt safer behaviors. The author explains why a gender perspective is important and writes that programs can incorporate a gender perspective in their design by taking into account the differing needs and opportunities of men and women. She considers learning about sexual health needs, sexual health services, use of the media, policy and law, changing organizations, and evaluation. Education on HIV/STDs is more likely to be effective in changing behaviors if it is incorporated into a broader program of sexual health promotion which includes contraception, gender relations, sexuality, sexual pleasure, and abuse.
Trends in Gender Segregation in the Choice of Science and Engineering Majors*

Mann, Allison; DiPrete, Thomas A.

2013-01-01

Numerous theories have been put forward for the high and continuing levels of gender segregation in science, technology, engineering, and mathematics (STEM) fields, but research has not systematically examined the extent to which these theories for the gender gap are consistent with actual trends. Using both administrative data and four separate longitudinal studies sponsored by the U.S. Department of Education’s National Center for Education Statistics (NCES), we evaluate several prominent explanations for the persisting gender gap in STEM fields related to mathematics performance and background and general life goals, and find that none of them are empirically satisfactory. Instead, we suggest that the structure of majors and their linkages to professional training and careers may combine with gender differences in educational goals to influence the persisting gender gap in STEM fields. An analysis of gendered career aspirations, course-taking patterns, and pathways to medical and law school supports this explanation. PMID:24090849

Cognitive development in children presents peculiarities according to groups of age, gender, and type of school. Few studies have been investigating the effects of all these factors. The aim of this study was to investigate the main effects and the interactions of age, gender, and type of school in 419 children from ages 6 to 12 years old evaluated by the Child Brief Neuropsychological Assessment Battery (NEUPSILIN-Inf). Older children, children in private schools and girls presented better results. Interactions between all three independent variables were observed in different cognitive domains. The results highlight both the heterogeneity and the influence of multiple factors in children's neuropsychological development.

Using data from Botswana's largest HIV testing and counseling (HTC) provider, Tebelopele, we evaluate populations served and gender-specific correlates of testing HIV-positive among clients of two programs: standalone centers and outreach testing. Client records from January to June 2007 (n = 47,890) were evaluated by HTC program and gender. Bivariate and multivariate analyses were performed to identify demographic, testing, and risk-behavior variables associated with testing HIV-positive. Compared to outreach testing, standalone centers served proportionally more clients who were young, well-educated, unmarried, and HIV-infected; outreach testing reached an older, less-educated population. Age, educational attainment, marital status, couples testing, testing because of illness or discordant relationship, and nonuse of condoms (among young clients only) were consistently associated with testing HIV-positive, by HTC program and gender. Our evaluation suggests that Tebelopele standalone and outreach HTC programs serve different populations, and identifies strategies to reduce HIV infection risk and to improve uptake of HTC by HIV-infected, undiagnosed Batswana.

During the paranasal sinuses surgery different complications may occur, both vascular and bony. The objective of the present study was to evaluate the ethmoidal roof configuration through the Keros and Yenigun classifications, analyzing results stratified by gender and side. We retrospectively analyzed 120 high-resolution computed tomography paranasal sinus study images and measured the depth of the cribriform plate in a coronal view and the anterior-posterior length in a cross section. The Keros Type II was the most frequent and no statistically significant difference was found when comparing by gender. Yenigun type I was more prevalent, and a statistically significant difference was found between men and women in types I and II (p = 0.010 and p = 0.049, respectively). Statistical difference was observed in anterior-posterior means in the comparison between both classifications. In both, right and left side for men (p = 0.003 and p = 0.05) and women (p = 0.029 and p = 0.039). We demonstrate the morphological variability that exists in this region. Gender differences that must be considered by the surgeon to avoid complications. Further studies are needed to evaluate the value of these findings when predicting surgical complications.

Career Advancement Outcomes in Academic Science, Technology, Engineering and Mathematics (STEM): Gender, Mentoring Resources, and Homophily

NASA Astrophysics Data System (ADS)

Lee, Sang Eun

This dissertation examines gender differences in career advancement outcomes among academic science, technology, engineering and mathematics (STEM) scientists. In particular, this research examines effects of gender, PhD advisors and postdoctoral supervisors mentoring resources and gender homophily in the mentoring dyads on the career advancement outcomes at early career stages. Female academic scientists have disadvantages in the career progress in the academic STEM. They tend to fall behind throughout their career paths and to leave the field compared to their male colleagues. Researchers have found that gender differences in the career advancement are shaped by gender-biased evaluations derived from gender stereotypes. Other studies demonstrate the positive impacts of mentoring and gender homophily in the mentoring dyads. To add greater insights to the current findings of female academic scientists' career disadvantages, this dissertation investigates comprehensive effects of gender, mentoring, and gender homophily in the mentoring dyads on female scientists' career advancement outcomes in academic science. Based on the Status Characteristics Theory, the concept of mentoring, Social Capital Theory, and Ingroup Bias Theory, causal path models are developed to test direct and indirect effects of gender, mentoring resources, and gender homophily on STEM faculty's career advancement. The research models were tested using structural equation modeling (SEM) with data collected from a national survey, funded by the National Science Foundation, completed in 2011 by tenured and tenure-track academic STEM faculty from higher education institutions in the United States. Findings suggest that there is no gender difference in career advancement controlling for mentoring resources and gender homophily in the mentoring dyads and other factors including research productivity and domestic caregiving responsibilities. Findings also show that the positive relationship between gender homophily in mentoring dyads and the reception of the mentoring resources, especially regarding providing help on career development and research collaboration, lead to enhanced early stage career advancement. Insights from the findings contribute both to theoretical understandings of the overall effects of gender, mentoring, and gender homophily in the mentoring dyads on female academic scientists' career advancement at early career stages and to provide evidence of positive effects of same-gender mentoring dyads to universities.

The ability to develop force quickly is a requisite ability in most sports. The reactive strength index (RSI) has been developed as a measure of explosive strength and is derived by evaluating jump height divided by ground contact time during the depth jump (DJ). At present, the RSI is typically used to evaluate DJ performance, because it is the only plyometric exercise with an identifiable ground contact time. The purpose of this study was to introduce a modification of the RSI (RSImod) that can be used to evaluate the explosive power of any vertical plyometric exercise. This study will also assess the reliability of the RSImod, evaluate the RSImod of a variety of plyometric exercises, and examine gender differences. Twenty-six men and 23 women served as subjects. Subjects performed 3 repetitions for each of 5 plyometric exercises including the countermovement jump (CMJ), tuck jump, single-leg jump, squat jump, and dumbbell CMJ. Data were analyzed using a 2-way analysis of variance to evaluate differences in RSImod between the plyometric exercise and the interaction between plyometric exercise RSImod and gender. The analysis of RSImod revealed significant main effects for plyometric exercise type (p 0.05). Results of pairwise comparisons indicate that the RSImod is statistically different between all plyometric exercises studied. Intraclass correlation coefficients indicate that RSImod is highly reliable for all of the exercises studied. The RSImod offers a highly reliable method of assessing the explosiveness developed during a variety of plyometric exercises.
Trends in Child Immunization across Geographical Regions in India: Focus on Urban-Rural and Gender Differentials

Background Although child immunization is regarded as a highly cost-effective lifesaver, about fifty percent of the eligible children aged 12–23 months in India are without essential immunization coverage. Despite several programmatic initiatives, urban-rural and gender difference in child immunization pose an intimidating challenge to India’s public health agenda. This study assesses the urban-rural and gender difference in child immunization coverage during 1992–2006 across six major geographical regions in India. Data and Methods Three rounds of the National Family Health Survey (NFHS) conducted during 1992–93, 1998–99 and 2005–06 were analyzed. Bivariate analyses, urban-rural and gender inequality ratios, and the multivariate-pooled logistic regression model were applied to examine the trends and patterns of inequalities over time. Key Findings The analysis of change over one and half decades (1992–2006) shows considerable variations in child immunization coverage across six geographical regions in India. Despite a decline in urban-rural and gender differences over time, children residing in rural areas and girls remained disadvantaged. Moreover, northeast, west and south regions, which had the lowest gender inequality in 1992 observed an increase in gender difference over time. Similarly, urban-rural inequality increased in the west region during 1992–2006. Conclusion This study suggests periodic evaluation of the health care system is vital to assess the between and within group difference beyond average improvement. It is essential to integrate strong immunization systems with broad health systems and coordinate with other primary health care delivery programs to augment immunization coverage. PMID:24023816

Despite increasing numbers of women attending medical school and completing residencies, women continue to lag behind men in academic achievement. Other specialties have found that women publish fewer journal articles than men. While family medicine is becoming increasingly gender balanced, the aim of this study was to evaluate the gender balance of published material within family medicine journals. All original articles were reviewed in five family medicine journals published in the United States (Family Medicine, Journal of Family Practice, Journal of the American Board of Family Medicine, Annals of Family Medicine, and American Family Physician) between 2006-2008. The articles were categorized based on type of publication and gender of first author. The editorial boards of each of the journals were examined to determine gender breakdown. A total of 2,126 articles were included in the study. Females were first author on 712 (33.5%) of the articles, and males authored 1,414 (66.5%). There was no significant difference between years. More female authors wrote original research, and fewer wrote letters to the editor. Only Family Medicine had gender parity on its editorial board. Female authors wrote about a third of all original publications in family medicine journals between 2006-2009 even though they comprise 44% of the faculty. Further research can evaluate reasons for this gender disparity.

As the workforce ages, occupational injuries from falls on the same level will increase. Some industries may be more affected than others. We conducted a cross-sectional study using data from the Bureau of Labor Statistics to estimate same-level fall injury incidence rates by age group, gender, and industry for four sectors: 1) healthcare and social assistance; 2) manufacturing; 3) retail; and 4) transportation and warehousing. We calculated rate ratios and rate differences by age group and gender. Same-level fall injury incidence rates increase with age in all four sectors. However, patterns of rate ratios and rate differences vary by age group, gender, and industry. Younger workers, men, and manufacturing workers generally have lower rates. Variation in incidence rates suggests there are unrealized opportunities to prevent same-level fall injuries. Interventions should be evaluated for their effectiveness at reducing injuries, avoiding gender- or age-discrimination and improving work ability. © 2017 Wiley Periodicals, Inc.
Values for gender roles and relations among high school and non-high school adolescents in a Maya community in Chiapas, Mexico.

In the current study, I describe values for gender roles and cross-sex relations among adolescents growing up in a southern Mexican Maya community in which high school was introduced in 1999. A total of 80 adolescent girls and boys, half of whom were attending the new high school, provided their opinions on two ethnographically derived vignettes that depicted changes in gender roles and relations occurring in their community. Systematic coding revealed that adolescents not enrolled in high school tended to prioritise ascribed and complementary gender roles and emphasise the importance of family mediation in cross-sex relations. Adolescents who were enrolled in high school tended to prioritise equivalent and chosen gender roles, and emphasised personal responsibility and personal fulfillment in cross-sex relations. Perceptions of risks and opportunities differed by gender: girls favourably evaluated the expansion of adult female role options, but saw risks in personal negotiations of cross-sex relations; boys emphasised the loss of the female homemaker role, but favourably evaluated new opportunities for intimacy in cross-sex relations. © 2014 International Union of Psychological Science.

Understanding sources of performance bias in science assessment provides important insights into whether science curricula and/or assessments are valid representations of student abilities. Research investigating assessment bias due to factors such as instrument structure, participant characteristics, and item types are well documented across a variety of disciplines. However, the relationships among these factors are unclear for tasks evaluating understanding through performance on scientific practices, such as explanation. Using item-response theory (Rasch analysis), we evaluated differences in performance by gender on a constructed-response (CR) assessment about natural selection (ACORNS). Three isomorphic item strands of the instrument were administered to a sample of undergraduate biology majors and nonmajors (Group 1: n = 662 [female = 51.6%]; G2: n = 184 [female = 55.9%]; G3: n = 642 [female = 55.1%]). Overall, our results identify relationships between item features and performance by gender; however, the effect is small in the majority of cases, suggesting that males and females tend to incorporate similar concepts into their CR explanations. These results highlight the importance of examining gender effects on performance in written assessment tasks in biology. PMID:26865642

Understanding the goals and aspirations of the physician-scientist workforce can inform policies to promote retention. The authors explored gender differences therein, given women's increasing representation. In 2010-2011, the authors qualitatively analyzed interviews with 100 former recipients of National Institutes of Health career development awards and 28 of their mentors. They also compared survey responses of 1,267 clinician-investigators who received these awards from 2006 to 2009, using logistic regression to evaluate gender differences after adjusting for other characteristics. Interview participants described relatively consistent career goals, including scientific contribution and desire to positively affect lives through research, clinical care, and teaching. For many, the specific ways they sought to achieve and measure goal attainment evolved over time. Survey respondents endorsed a goal of publishing high-quality research with highest frequency (97.3%, no significant gender difference). Women were more likely to endorse the importance of balancing work and other activities (95.5% vs. 90.5%, P < .001). There were no significant gender differences in the importance of patient care (86.6%), teaching (71.6%), or publishing prolifically (64.9%). Men were more likely than women to consider salary (49.4% vs. 41.8%, P < .001), reputation (84.2% vs. 77.6%, P = .004), and leadership positions (38.9% vs. 34.3%, P = .03) important. In an elite research-oriented sample, gender differences in initial aspirations were generally limited. Gender differences in career outcomes in such groups are unlikely to exclusively result from different baseline aspirations. Goals appear to evolve in response to challenges experienced.

Eating behavior and physical activity behavior are under the control of certain cognitive patterns. 6600 adults and 4400 children/adolescents (8-18 years) were tested with the Obesity Diagnostics and Evaluation System (AD-EVA). Potentially significant gender differences will be detailed for the entire juvenile cohort, the subgroup of obese children/adolescents as compared to the adult cohort in this article.Among all the subscales tested, obese girls primarily showed significantly higher values of (preclinical) eating disorders than boys. These data are relevant for both prevention and health promotion.No significant differences were found in regard to sports motivation. This warrants facilitation of physical activity for both genders. Further, a male predilection for "Snacks" and "High-fat food" that could be found in the total representative study group, could not be verified in the subgroup of obese girls and boys, thus suggesting a similarily unhealthy eating behavior in both genders of juvenility.

The purpose of the study was to evaluate possible differences between genders in amputation incidence, revascularization activity before and survival after amputation. This population-based study was carried out in a well-defined geographical area, where all vascular surgical consultations and reconstructions are performed in one university hospital. All amputations performed in the region during 1990 - 1999 were identified from the hospital central registers. According to patient's identity codes, the Cause of Death Registry of Statistics Finland provided death data. Amputation data were cross-linked with the local vascular registry using identity codes. Women were found to be 8 years older than men (p < 0.0001). Major amputations comprised 73.4% in males and 77.7% in females. The age-standardized amputation incidence among males was 338 and among females 226 (per 10(6) inhabitants/year) (p < 0.001). The most prominent difference was seen in amputations due to trauma, where the age-adjusted major amputation incidence was over three-fold among males compared to females. The proportion of patients who had undergone vascular procedure before amputation was 23% in both genders. Median survival after amputation was 943 days in men and 716 in women (p = 0.01). When the higher age of women was considered, there was no significant difference between the genders. Survival was poorer among diabetics in both genders and the difference was significant in males. The amputation incidence was found to be higher in men compared to women in all etiologic subgroups except malignant tumour. Almost one in 4 patients had undergone vascular surgical reconstruction before amputation in both genders. There was no significant difference between the genders in survival after amputation. Subjects with diabetes had a poorer survival after major amputation than those without diabetes.

The aim of this study was to investigate the current situation and the research agenda in the field of gender differences, both generically in the occupational settings and in the specific activity of risk assessment. Gender is a key determinant of health; the evaluation of documents and scientific literature shows increasing attention to a gender oriented approach, as demonstrated by the development of Gender Medicine, actually cross-oriented in all medical specialties, the publication of books dedicated to this topic and the birth of "ad hoc" new scientific societies and journals. Even today, however, the gender differences are not considered as they should in the context of health disciplines, including occupational medicine. In this respect, in fact, the critical issues to be overcome are numerous, such as the phenomena of "segregation", the exposure to risk factors and their effects, related also to non-professional, socio-cultural features that differentiate male and female workers. All these factors can lead to situations of inequality in health. In fact, the European directives on safety at work repeatedly highlight the attention to gender differences in prevention, assessment and management of risks. In this regard, the European Agency for Safety and Health at Work advocates an approach "more sensitive" to gender in all the processes of assessment and risk management, from the research of all potential sources of risk to the decision-making processes, in order to address the prevention of risks in a holistic manner.

Quality of working life is the result of many factors inherent in the workplace environment, especially in terms of exposure to psychosocial risks. The purpose of this study is to assess the quality of life with special attention to gender differences. The HSE-IT questionnaire and the WHO-5 Well-Being Index were administered to a group of workers (74 males and 33 females). The authors also used Cronbach's alpha test to assess the internal consistency of both questionnaires and the Mann-Whitney test to evaluate the significance of gender differences in both questionnaires. The HSE-IT highlighted the existence of work-related stress in all the population with a critical perception regarding the domain "Relationships." Furthermore, gender analysis highlighted the presence of two additional domains in the female population: "Demand" ( p = 0,002) and "Support from Managers" ( p = 0,287). The WHO-5 highlighted a well-being level below the standard cut-off point with a significant gender difference ( p = 0.009) for males (18, SD = 6) as compared to females (14, SD = 6,4). Cronbach's alpha values indicated a high level of internal consistency for both of our scales. The risk assessment of quality of working life should take into due account the individual characteristics of workers, with special attention to gender.

This study investigated the effects of progesterone (PROG) on neonatal hypoxic/ischemic (NHI) brain injury, the differences in effects between genders, and the underlying mechanisms. NHI brain injury was established in both male and female neonatal mice induced by occlusion of the left common carotid artery followed by hypoxia. The mice were treated with PROG or vehicle. Fluoro-Jade B staining (F-JB), long term behavior testing, and brain magnetic resonance image (MRI) were applied to evaluate neuronal death, neurological function, and brain damage. The underlying molecular mechanisms were also investigated by Western blots. The results showed that, in the male mice, administration of PROG significantly reduced neuronal death, improved the learning and memory function impaired by cerebral HI, decreased infarct size, and maintained the thickness of the cortex after cerebral HI. PROG treatment, however, did not show significant neuroprotective effects on female mice subjected to HI. In addition, the data demonstrated a gender difference in the expression of tumor necrosis factor receptor 1 (TNFR1), TNF receptor associated factor 6 (TRAF6), Fas associated protein with death domain (FADD), and TIR-domain-containing adapter-inducing interferon-β (TRIF) between males and females. Our results indicated that treatment with PROG had beneficial effects on NHI injured brain in acute stage and improved the long term cognitive function impaired by cerebral HI in male mice. In addition, the activation of TNF and TRIF mediated signaling in response to cerebral HI and the treatment of PROG varied between genders, which highly suggested that gender differences should be emphasized in evaluating neonatal HI brain injury and PROG effects, as well as the underlying mechanisms.

Conceptual physics differences by pedagogy and gender: Questioning the deficit model

NASA Astrophysics Data System (ADS)

Majors, Twanelle Deann Walker

The differences in physics performance between males and females have been studied extensively (Blue & Heller, 2003; Coletta, 2015; Madsen, McKagan, & Sayre 2013; McCullough, 2002, 2004, 2011; Pollock, Finkelstein, & Kost, 2007; Zohar & Sela, 2003). The purpose of this study was to look at the ways teaching methods and assessment choices have fabricated a gender gap. Deficit ways of thinking have further marginalized women by renegotiating prior acts of power that initiated and perpetuated marginalization. Outside of the deficit model, the blame for the underperformance of females has been attributed to discourses of power as well as less-than-critical ways of evaluating learning and schooling. Students in introductory algebra-based physics courses from 2008-2014 at Tennessee Technological University were self-enrolled in PHYS2010 sections that were taught using either a traditional or constructivist, interactive-engagement Learner-centered Environment for Algebra-based Physics (LEAP) pedagogy. Propensity scoring on all feasible and relevant independent variables was used to adjust for the probability of students choosing either LEAP or traditional sections. The Force Concept Inventory (FCI) and Gender Force Concept Inventory (GFCI) were used as the measures to gauge students' performance on physics concepts. The results showed that there were no differences in the FCI or GFCI performance of males and females. Results also showed that when accounting for pretest performance and the likelihood of choosing a LEAP section, LEAP pedagogy accounted for roughly 30% of performance differences. Not only was this true on the average, it was true for both genders. This meant that the main effect of LEAP pedagogy was even stronger and more generalizable. Gender did not moderate pedagogy, indicating that a pedagogy gap focus was more appropriate for evaluating physics learners.

Gender bias continues to be a concern in many work settings, leading researchers to identify factors that influence workplace decisions. In this study we examine several of these factors, using an organizing framework of sex distribution within jobs (including male- and female-dominated jobs as well as sex-balanced, or integrated, jobs). We conducted random effects meta-analyses including 136 independent effect sizes from experimental studies (N = 22,348) and examined the effects of decision-maker gender, amount and content of information available to the decision maker, type of evaluation, and motivation to make careful decisions on gender bias in organizational decisions. We also examined study characteristics such as type of participant, publication year, and study design. Our findings revealed that men were preferred for male-dominated jobs (i.e., gender-role congruity bias), whereas no strong preference for either gender was found for female-dominated or integrated jobs. Second, male raters exhibited greater gender-role congruity bias than did female raters for male-dominated jobs. Third, gender-role congruity bias did not consistently decrease when decision makers were provided with additional information about those they were rating, but gender-role congruity bias was reduced when information clearly indicated high competence of those being evaluated. Fourth, gender-role congruity bias did not differ between decisions that required comparisons among ratees and decisions made about individual ratees. Fifth, decision makers who were motivated to make careful decisions tended to exhibit less gender-role congruity bias for male-dominated jobs. Finally, for male-dominated jobs, experienced professionals showed smaller gender-role congruity bias than did undergraduates or working adults. (c) 2015 APA, all rights reserved.

Cost-related non-adherence (CRN) to medical care is a persistent challenge in healthcare in the US. Gender is a key determinant of many healthcare behaviors and outcomes. Understanding variation in CRN by gender may provide opportunities to reduce disparities and improve outcomes. This study aims to examine the differential rates in CRN by gender across a spectrum of socio-economic factors among the adult population in the US. Data from the 2015 National Financial Capability Study (NFCS) were used for this study. CRN is identified if a respondent indicated not filling a prescription for medicine because of the cost and/or skipping a medical test, treatment, or follow-up recommended by a doctor because of the cost in the past 12 months. The differential rates in CRN by gender were assessed across socio-economic strata. A multivariable logistic regression analysis was performed to evaluate the difference in CRN rates by gender, controlling for potential confounders. A total of 26,287 adults were included in the analyses. Overall, the weighted CRN rate in the adult population is 19.8% for men and 26.2% for women. There was a clear pattern of differential rates in CRN across socio-economic strata by gender. Overall, men were less likely to report CRN (AOR = 0.74; 95% CI = 0.69-0.79), controlling for other risk factors. More research is needed to understand the behavioral aspects of gender difference in CRN. Patient-centered healthcare needs to take gender difference into account when addressing cost-related non-adherence behavior.

Partial edentulism, one or more teeth missing is an indication of healthy behaviour of dental practices in the society and attitude towards dental and oral care. The pattern of partial edentulism has been evaluated in many selected populations in different countries by different methods. Most of the studies have evaluated partial edentulism by surveying of Removable Partial Dentures (RPDs), patients visiting clinics, clinical records and population in particular locality. The objective of the study is to review the prevalence of partial edentulousness and its correlation to age,gender, arch predominance, socio economic factors and incidence of various Kennedy’s Classes. Key observations drawn from the review are as below. There is no gender correlation for partial edentulism.Prevalence of partial edentulism is more common in mandibular arch than maxillary arch.Younger adults have more Class III and IV RPDs. Elders have more distal extension RPDs Class I and II. PMID:26266237
The Role of Self-esteem and Fear of Negative Evaluation in Compulsive Buying

Compulsive buying is a relatively new addictive disorder that interferes with everyday functioning and may result in serious psychological and financial problems (1). A very few data are currently available regarding this behavioral addiction. This study investigated gender differences in the relationships between contingent self-esteem (CSE), fear of negative evaluation (FNE), and compulsive buying. Participants included 240 Italian adults (170 females, M age = 33.80) who responded to self-report questionnaires. The results showed that women scored higher on CSE and FNE scales than men. No gender differences were found in compulsive buying tendencies. CSE and FNE were positively related to CB. Furthermore, structural equation modeling confirmed the evidence on CSE as a strong predictor of CB for both genders. Interestingly, FNE seems to play a mediating role between CSE and compulsive buying behaviors only for women. These findings highlight the importance of studying self-esteem in compulsive buying tendencies to inquire more deeply into the underlying mechanisms of some compulsive behaviors. PMID:28512435

Gender identity development is poorly understood but impacted by central nervous system (CNS) factors, genes, gonadal hormones and receptors, genitalia, and social/environmental factors. Gender identity disorder (GID) is the diagnostic term to describe persons discontent with the sex they were assigned at birth and/or the gender roles associated with that sex. It is crucial that the diagnosis be verified as persistent, since gender confusion among those young persists among only a portion. Recent publications do not yet provide an overall perspective but involve observations regarding outcome information, unusual variables, incidence of cross-gender behavior, and CNS differences related to GID and bi-gender descriptions. Approaches to therapy for GID and task force guidelines are noted. Although the concept of gender identity is a relatively new paradigm and remains an area of active and exciting investigation, findings reported here provide items of information for understanding and treatment of GIDs and illustrate the need for further research.

To determine similarities and differences in the performance of female and male athletes on neuropsychological measures of frontal lobe functioning. A cross-sectional study of male and female college-aged athletes involved in one of the following sports: hockey, basketball, softball, lacrosse, soccer, swimming, and track. Division III college. A total of 262 athletes (male, n=157; female, n=105) participated in the study. Controlled Oral Word Association (letters F, A, S), Cognitive Assessment System (Planned Codes, Planned Connections, Number Detection), and WAIS-R-NI Vocabulary were administered to all athletes. MANCOVA was performed with gender and sport as fixed factors. Female athletes displayed faster and more accurate performance on perceptual-motor tasks (P<0.01) and on one condition of a verbal fluency task (P<0.01) compared with male athletes. Male hockey athletes showed superior perceptual-motor speed and accuracy (P<0.01) compared with male athletes in the track/swimming group. Evaluators were naive to athletes' gender and sport. Gender- and sport-specific performances on perceptual-motor and verbal fluency tasks were found. Adding cognitive components to base functions eliminates gender- and sports-related distinctions, suggesting that existing differences are related to basic, fundamental skills, which are inherent and practiced within the respective sport. Understanding the differences and similarities across sports and gender on various neurocognitive measures is relevant for determining group differences in studies examining the consequences of mild traumatic brain injury among athletes.

Gender studies report a male advantage in several visuospatial abilities. Only few studies however, have evaluated differences in visuospatial planning behaviour with regard to gender. This study was aimed at exploring whether gender may affect the choice of cognitive strategies in a visuospatial planning task and, if oculomotor measures could assist in disentangling the cognitive processes involved. A computerised task based on the travelling salesperson problem paradigm, the Maps test, was used to investigate these issues. Participants were required to optimise time and space of a path travelling among a set of sub-goals in a spatially constrained environment. Behavioural results suggest that there are no gender differences in the initial visual processing of the stimuli, but rather during the execution of the plan, with males showing a shorter execution time and a higher path length optimisation than females. Males often showed changes of heuristics during the execution while females seemed to prefer a constant strategy. Moreover, a better performance in behavioural and oculomotor measures seemed to suggest that males are more able than females in either the optimisation of spatial features or the realisation of the planned scheme. Despite inconclusive findings, the results support previous research and provide insight into the level of cognitive processing involved in navigation and planning tasks, with regard to the influence of gender.

The aim of this study was to measure the mandibular cortical index (MCI), mental index (MI), panoramic mandibular index (PMI) and cortical bone thickness in the zone of the gonial angle (GT) in panoramic radiographies from a large sample of males and females and to determine how they relate to patients' age, gender and dental status. 910 panoramic radiographs were obtained and grouped into age, dental status and gender. The MCI, MI, PMI and GT were analysed. Remarkable differences were observed for MCI and GT regarding gender, age groups and dental status on both sides (p < 0.05). While age and dental status had an effect on the MI and PMI in females, dental status had an effect on the MI and PMI in males (p < 0.05). Also, gender had an effect on the MI and PMI (p < 0.05). The effects of age and tooth loss are different in females and males. In females, the harmful effects of tooth loss and age are more prominent according to the PMI and MI measurements. The effects of age and tooth loss in the GT and MCI measurements are similar, and these indices can be accepted as more reliable in studies including both genders.

Gender differences in brain dopaminergic activity have been variably reported in the literature. We performed an evaluation for gender effects on striatal dopamine transporter (DAT) binding in a group of normal subjects. Community-dwelling adults (n = 85, 50F/35M, mean age 62.7 ± 16.2 SD, range 20-85) underwent DAT [(11)C]2-β-carbomethoxy-3β-(4-fluorophenyl) tropane (β-CFT) positron emission tomography (PET) imaging. Gender effects for DAT binding were compared using ANCOVA for two subgroups; young-to-middle aged adults and older adults, using an age threshold of 60 years. There were 54 subjects (24M/30F; mean age 72.9 ± 7.3) 60 years and older and 31 (11M/20F; mean age 45.0 ± 11.4) subjects younger than 60. Age-adjusted striatal DAT gender effects were present in the young-to-middle (F = 10.4, P = 0.003) but not in the elderly age group (F = 0.5, ns). Gender differences in nigrostriatal dopaminergic innervation are present, with higher levels of DAT binding in young-to-middle age women compared to men, but not present in the elderly.

Dermatological patients invariably suffer one or the other psychological problems which may escalate to the extent of a mental disorder. One of the most common dermatological disorders is atopic dermatitis (AD), but the literature has limited data on gender differences for psychiatric morbidity in such patients. To evaluate and compare gender differences in the prevalence of depression and anxiety in AD. This cross-sectional study with consecutive sampling was done in an outpatient clinic of Dermatology at a Tertiary Care Center. AD subjects giving informed consent were evaluated on a brief semi-structured performa for collecting demographic and clinical information. Primary Care Evaluation of Mental Disorders (PRIME-MD) was used to assess the presence of psychiatric symptoms in these patients. Descriptive analysis was done for the socio-demographic profile and independent sample t-test, Chi-square and Cramer's V test was carried out to find in-between group differences for males and females. A total of 81 patients were included in the final analysis (males = 36, females = 45) with no significant difference in mean age between male and female subjects (36.14 ± 17.62 and 33.98 ± 14.49 years, respectively; P = 0.54). When including moderate to severe grade of depression or anxiety, the current study found prevalence rates of 15% and 12% respectively. Females had significantly more anxiety and depression scores than males (P = 0.04 and P = 0.03 respectively). There is a female preponderance of depression and anxiety disorder in AD patients.

Individuals that combine features of both genders-gender blends-are sometimes appealing and sometimes not. Heretofore, this difference was explained entirely in terms of sexual selection. In contrast, we propose that part of individuals' preference for gender blends is due to the cognitive effort required to classify them, and that such effort depends on the context in which a blend is judged. In two studies, participants judged the attractiveness of male-female morphs. Participants did so after classifying each face in terms of its gender, which was selectively more effortful for gender blends, or classifying faces on a gender-irrelevant dimension, which was equally effortful for gender blends. In both studies, gender blends were disliked when, and only when, the faces were first classified by gender, despite an overall preference for feminine features in all conditions. Critically, the preferences were mediated by the effort of stimulus classification. The results suggest that the variation in attractiveness of gender-ambiguous faces may derive from context-dependent requirements to determine gender membership. More generally, the results show that the difficulty of resolving social category membership-not just attitudes toward a social category-feed into perceivers' overall evaluations toward category members.

Violent behaviour associated with alcohol consumption is frequently reported by different media. Clinical data analysing the correlation between alcohol intoxication, age, gender and violence are scarce. The aim of this study was to evaluate the influence of age, gender and blood alcohol content on violent behaviour under the influence of alcohol under central European conditions. Three hundred patients admitted to the emergency department were included into this study in the time period from January 01. to December 31. 2009. The inclusion criteria were a blood alcohol content (BAC) of ≥10 mmol/l, any traumatic injury and an age ≥16 years. Violence was defined as an evitable act committed by others leading to patient's hospitalisation. The data were compared with Wilcoxon and χ2-test for proportions. The data were considered as significant if p<0,05. Predictive quality was evaluated by using receiver operating characteristic (ROC) curve. Independent predictors were analyzed by logistic regression analysis. The average age was 36,9±16,9 years (range: 16-84 years), 259 (86%) males and 41 (24%) females. There was a significant difference in gender (odds ratio for gender male 2,88; CI 95%: 1,24-6,67; p<0,001) and age dependent (odds ratio for each year of age 0,94; CI 95%: 0,93-0,96; p<0,0001) violence with no correlation to blood alcohol content found. Logistic regression analysis revealed male gender and young age as an independent predictor for violence. These results clarify the relationship between alcohol, age, gender and violence and have important implications for municipal-level alcohol policies.
Comparison of 2015 Medicare relative value units for gender-specific procedures: Gynecologic and gynecologic-oncologic versus urologic CPT coding. Has time healed gender-worth?

In 1992, Congress implemented a relative value unit (RVU) payment system to set reimbursement for all procedures covered by Medicare. In 1997, data supported that a significant gender bias existed in reimbursement for gynecologic compared to urologic procedures. The present study was performed to compare work and total RVU's for gender specific procedures effective January 2015 and to evaluate if time has healed the gender-based RVU worth. Using the 2015 CPT codes, we compared work and total RVU's for 50 pairs of gender specific procedures. We also evaluated 2015 procedure related provider compensation. The groups were matched so that the procedures were anatomically similar. We also compared 2015 to 1997 RVU and fee schedules. Evaluation of work RVU's for the paired procedures revealed that in 36 cases (72%), male vs female procedures had a higher wRVU and tRVU. For total fee/reimbursement, 42 (84%) male based procedures were compensated at a higher rate than the paired female procedures. On average, male specific surgeries were reimbursed at an amount that was 27.67% higher for male procedures than for female-specific surgeries. Female procedure based work RVU's have increased minimally from 1997 to 2015. Time and effort have trended towards resolution of some gender-related procedure worth discrepancies but there are still significant RVU and compensation differences that should be further reviewed and modified as surgical time and effort highly correlate.

Gender bias in the diagnosis and assessment of borderline personality disorder (BPD) has been the subject of much controversy in the psychological research literature. Evidence regarding differential prevalence rates and diagnostic rates in clinical settings between genders has been mixed, and measurement bias is one potential explanation for these mixed findings. A total of 340 participants were recruited from a Midwestern university and four outpatient community mental health clinics. They were administered two structured clinical interviews for BPD that were then evaluated for measurement invariance. Both the SCID-II BPD scale and the PDI-IV BPD scale were found to be measurement invariant between genders. No significant differences were found on the SCID-II BPD scale in diagnosis or overall number of criteria endorsed. However, in the rates of endorsement of individual criteria, differences were found in the unstable relationships item.

The aim of this study was to evaluate the effect of different kinds of music on submaximal performance and exercise tolerance in healthy children by means of the 6-minute walking test (6MWT) and to explore the influence of gender. Cross-over study. Ninety-seven children performed 6MWT in four conditions (without music, with their preferred music, with slow and with fast music). Distance, cardio-respiratory parameters, perceived exertion rate, and amount of dyspnea were measured. Walked distance depended on the kind of music (p = .022). To listen to fast music promoted a longer distance when compared with slow music. Walked distance was not influenced by gender (p = .721) and there was no interaction between music and gender for walked distances (p = .069). The other parameters were not modified by music and gender. Music influences submaximal performances without modifying exercise tolerance in healthy children. Music does modify submaximal performance in children.
Considering lesbian identity from a social-psychological perspective: two different models of "being a lesbian".

PubMed

Tate, Charlotte Chuck

2012-01-01

One long-standing project within lesbian studies has been to develop a satisfactory working definition of "lesbian." This article proposes two new models of a definition using principles of social psychology. Each model (a) utilizes the premise that gender lacks a categorical essence and (b) separates behavioral adherence to cultural stereotypes of femininity and masculinity from one's gender self-categorization. From these premises, I generate and critique two internally coherent models of lesbian identity that are inclusive (to different degrees) of various gender identities. For each model, the potential inclusion of trans men, trans women, genderqueers, and lesbian-identified cisgender men is evaluated. The explanatory power of these models is twofold. One, the models can serve as theoretical perspectives for scholars who study the intersection of gender and sexual identity. Two, the models can also characterize the everyday experience of people who have tacit working definitions of lesbian identity.
Introduction/overview: gender-based differences in pharmacologic and toxicologic responses.

Christian, M S

2001-01-01

Gender may be the most important factor in mammalian development and response to exogenous agents. From believing sex-related differences required sheltering women to protect their reproductive capacity (Victorians thought exercise, education, train travel, and certain music neuro- and reprotoxic to females) to legislating a status of essential equality of the sexes may have increased women's health issues. Men and women often respond differently to drugs. Inclusion of women in phase I/II clinical trials is insufficient to identify gender-based differences in response; rather, animal models should be the basis for predicting gender-based differences in pharmacologic and toxicologic effects. Unfortunately, current animal models do not consistently demonstrate such differences. Use of commonly used species (e.g., rats and dogs) does not necessarily result in relevant evaluation of an agent in a species at appropriate development (age), physiological state, anatomy, metabolism, or kinetics for estimation of human risks. The need to test agents in relevant animal models and advances in metabolic, pharmacokinetic, and pharmacodynamic capabilities challenge us to improve methods by using the most relevant models for estimating human risk. We need to be concerned about gender-related differences and the dynamics of gender-based growth and development over the entire life cycle. We must also consider potential interactions of dietary supplements and other exogenous agents that can act as drugs or modulate the potential effects of drugs differently in men, women, and developing children of both sexes. To this end, the health benefits of genistein and the effects of this dietary agent in a multigeneration study in rats will be described. It is envisioned that this symposium will assist in re-recognition of the importance of gender-related differences in use and response to pharmaceuticals and result in optimization of nonclinical testing procedures to identify benefits and risks for human use of these agents.

Virtual simulations recreate scenarios where student nurses can practice procedures in a safe and supervised manner and with no risk to the patient. Virtual scenarios include digital characters that reproduce human actions. Generally, these characters are modeled as males and restricted roles are assigned to females. Our objective is to evaluate how the character gender of a victim in a scenario created to practice the cardiopulmonary resuscitation protocol (CPR) affects performance of student nurses. Three virtual scenarios with cardiac arrest victims modeled as males or females were assigned to 41 students of the Nursing Faculty to practice the CPR protocol. We evaluated student performance with respect to the time to remove clothes, the time to perform the CPR maneuver, and the hands position for CPR. Chi-square, Fisher exact, and Mann-Whitney U were used to test primary outcome measures in the experimental design of victim character sex (male vs. female) and student sex (men vs. women). The analysis performed did not find statistically differences in time to remove clothes or in time to start CPR. With respect to hands placement we also did not find significant difference in any of the cases. Nurse student actions are not influenced by the character gender of the victim. Excellent results with respect to hands placement to start CPR are obtained. Virtual scenarios can be a suitable strategy to reduce gender differences in gender sensitive situations such as CPR performance. Copyright © 2018 Elsevier B.V. All rights reserved.

Stress experienced in competitive basketball was investigated in a sample of 84 men and 49 women recruited from players engaged in regular, organized, competitive grade basketball. Subjects were administered the Stressful Situations in Basketball Questionnaire which provides measures on 5 types of stress in competitive basketball. Analyses of gender differences showed that men reported more stress than female players on the "Team performance" scale. Research is required to evaluate whether this difference is due to a perception of women that they have less influence over the performance of the team or whether it is due to men having a higher stake in the results of competition.

Human beings have a basic need for esteemed social connections, and receiving negative self-evaluative feedback induces emotional distress. The aim of the current study is to measure eye movements (a physiological marker of attention allocation) and pupillary responses (a physiological marker of cognitive and emotional processing) as online and objective indices of participants' reaction to positive/negative social evaluations from the same or opposite sex. Following the paradigm, subjective mood ratings and heart rate variability (HRV) - as an objective index of regulatory effort- were measured. Results demonstrate clear gender-specific results in all measures. Eye-movements demonstrate that male participants respond more with other-focused attention (and specifically to male participants), whereas women respond more with self-focused attention following negative social evaluative feedback. Pupillary responses show that social evaluative feedback is specifically eliciting cognitive/affective processes in male participants to regulate emotional responses when provided by the opposite gender. Finally, following the paradigm, female (as compared to male) participants were more subjectively reactive to the paradigm (i.e., self-reports), and were less able to engage contextual- and goal related regulatory control of emotional responses (reduced HRV). Although the current study focused on psychiatrically healthy young adults, results may contribute to our understanding of sex differences in internalizing mental problems, such as rumination.

Background There is increasing recognition of sex/gender differences in health and the importance of identifying differential effects of interventions for men and women. Yet, to whom the research evidence does or does not apply, with regard to sex/gender, is often insufficiently answered. This is also true for systematic reviews which synthesize results of primary studies. A lack of analysis and reporting of evidence on sex/gender raises concerns about the applicability of systematic reviews. To bridge this gap, this pilot study aimed to translate knowledge about sex/gender analysis (SGA) into a user-friendly ‘briefing note’ format and evaluate its potential in aiding the implementation of SGA in systematic reviews. Methods Our Sex/Gender Methods Group used an interactive process to translate knowledge about sex/gender into briefing notes, a concise communication tool used by policy and decision makers. The briefing notes were developed in collaboration with three Cochrane Collaboration review groups (HIV/AIDS, Hypertension, and Musculoskeletal) who were also the target knowledge users of the briefing notes. Briefing note development was informed by existing systematic review checklists, literature on sex/gender, in-person and virtual meetings, and consultation with topic experts. Finally, we held a workshop for potential users to evaluate the notes. Results Each briefing note provides tailored guidance on considering sex/gender to reviewers who are planning or conducting systematic reviews and includes the rationale for considering sex/gender, with examples specific to each review group’s focus. Review authors found that the briefing notes provided welcome guidance on implementing SGA that was clear and concise, but also identified conceptual and implementation challenges. Conclusions Sex/gender briefing notes are a promising knowledge translation tool. By encouraging sex/gender analysis and equity considerations in systematic reviews, the briefing notes can assist systematic reviewers in ensuring the applicability of research evidence, with the goal of improved health outcomes for diverse populations.

Many studies have looked at differences between men and women with acute coronary syndrome. These studies demonstrate that women have worse outcomes, receive fewer invasive interventions, and experience delay in the initiation of established medical therapies. Using innovative technology, we set out to unveil and resolve any gender disparities in the evaluation and treatment of patients presenting with a positive troponin while in the emergency department. Our goal was to assess the feasibility of using a business management query system to create an automated data report that could identify deficiencies in standards of care and be used to improve the quality of treatment we provide our patients. Over a 12-month period, key markers for patients with non-ST elevation myocardial infarction (NSTEMI) were tracked (e.g., time to electrocardiogram, door to medications). During this time, educational endeavors were initiated utilizing McKesson's Horizon Business Insight™ (McKesson Information Solutions, Alpharetta, GA) to illustrate gender differences in standard therapy. Subsequently, indicators were evaluated for improvement. Substantial improvements in key indicators for management of NSTEMI were obtained and gender differences minimized where education was provided. The integration of these information systems allowed us to create a successful performance improvement tool and, as an added benefit, nearly eliminated the need for manual retrospective chart reviews.

Gender roles, suicidal ideation, and self-harming in young adults.

Straiton, Melanie L; Roen, Katrina; Hjelmeland, Heidi

2012-01-01

This study investigates whether positive and negative conventional gender roles relate to suicidal ideation and self-harming in different ways among young adults. Participants completed an online survey about previous self-harm, recent suicidal ideation, and positive and negative aspects of conventional masculinity and femininity. Logistic regression analyses showed that negative femininity positively predicted self-harm and recent suicidal ideation status. Positive femininity was unrelated. Positive masculinity was negatively related to suicidal ideation and self-harming while negative masculinity was negatively related to self-harming only. The findings suggest that it is not the conventional feminine gender role per se that is associated with suicidality but specific negatively evaluated aspects. Conceptualizing gender as a multivariate construct may be useful in the gender socialization theory of suicidal behavior.

In Germany gender-sensitive approaches are part of guidelines for good epidemiological practice as well as health reporting. They are increasingly claimed to realize the gender mainstreaming strategy in research funding by the federation and federal states. This paper focuses on methodological aspects of data analysis, as an empirical data example of which serves the health report of Bremen, a population-based cross-sectional study. Health reporting requires analysis and reporting methods that are able to discover sex/gender issues of questions, on the one hand, and consider how results can adequately be communicated, on the other hand. The core question is: Which consequences do a different inclusion of the category sex in different statistical analyses for identification of potential target groups have on the results? As evaluation methods logistic regressions as well as a two-stage procedure were exploratively conducted. This procedure combines graphical models with CHAID decision trees and allows for visualising complex results. Both methods are analysed by stratification as well as adjusted by sex/gender and compared with each other. As a result, only stratified analyses are able to detect differences between the sexes and within the sex/gender groups as long as one cannot resort to previous knowledge. Adjusted analyses can detect sex/gender differences only if interaction terms have been included in the model. Results are discussed from a statistical-epidemiological perspective as well as in the context of health reporting. As a conclusion, the question, if a statistical method is gender-sensitive, can only be answered by having concrete research questions and known conditions. Often, an appropriate statistic procedure can be chosen after conducting a separate analysis for women and men. Future gender studies deserve innovative study designs as well as conceptual distinctiveness with regard to the biological and the sociocultural elements of the category sex/gender.

Past research has indicated gender differences in the clinical characteristics and course of schizophrenia. In this study, we investigated whether gender differences in the manifestation of schizophrenia are correlated with neurosteroids, including dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), and pregnenolone. We further explored the potential relationship between the aforementioned neurosteroids and psychopathology. We recruited 65 schizophrenic patients (36 males and 29 females) and 103 healthy control subjects (47 males and 56 females) and obtained blood samples from the subjects in the morning while in a fasting state to determine the serum levels of DHEA, DHEA-S, and pregnenolone. The psychopathology and mood symptoms of patients with schizophrenia were evaluated using the Positive and Negative Syndrome Scale (PANSS) and 17-item Hamilton Depression Rating Scale, respectively. Compared to the male control subjects, male patients with schizophrenia had significantly lower serum levels of DHEA and pregnenolone. In males with schizophrenia, the serum levels of DHEA and DHEA-S were associated with the age of onset and the duration of illness, while pregnenolone levels were associated with general symptoms of the PANSS. However, none of the neurosteroid levels were different between the female patients with schizophrenia and the female controls, and no significant correlation between neurosteroid levels and psychopathology evaluations was found among the schizophrenic females. Neurosteroids, including DHEA, DHEA-S, and pregnenolone, are involved in the pathophysiology of schizophrenia in male patients, but not in female ones. Therefore, our findings suggest that neurosteroids may be associated with gender differences in susceptibility to schizophrenia. Copyright © 2017 Elsevier Ltd. All rights reserved.

Both biological and psychosocial factors influence psychosexual development. High levels of pre- and postnatal androgens lead to more male-typical behavior. So far, the influence of androgens on gender identity and sexual orientation is unclear. Disorders of sex development (DSDs) are heterogeneous genetic conditions with different levels of prenatal androgens resulting in variations of genital development. Through DSD, the role of the different factors, especially androgen exposure, on psychosexual development can be evaluated. The purpose of the study was to assess psychosexual development in adolescents and adults with different forms of DSD. For the examination of psychosexual development of 66 adolescents and 110 adults with DSD, the authors used the Utrecht Gender Dysphoria Scale for adolescents, the Questionnaire of Gender Identity for adults, and a condition-specific DSD study questionnaire. Individuals were analyzed in four subgroups reflecting the karyotype, absence/presence of androgen effects, and gender of rearing. Main outcome measures used were gender identity, friendships, love and sexual relationships, and sexual orientation in adolescents and adults with DSD. Individuals with DSD did not show increased gender dysphoria. However, partnership and sexuality were identified to be difficult areas of life. Both adolescents and adults with DSD reported fewer experiences regarding love or sexual relationships compared with unaffected individuals. Especially men with DSD and undervirilization and women with DSD and androgen effects less often had a love relationship. Adult women with DSD and androgen effects more frequently engaged in love and sexual relationships with individuals of the same gender compared with women without DSD. Individuals with DSD experience atypical hormonal influences (higher levels of androgens in girls/women and lower levels in androgens in boys/men); however, they did not show increased gender dysphoria in this study. However, partnership and sexual relationships are difficult areas of life for adolescents and adults with DSD. We recommend that individuals with DSD should get support from a multiprofessional team with competency in assessing and counseling issues regarding relationships and sexuality. Contact to other individuals with DSD can be helpful for nonprofessional support and exchange of experiences. © 2012 International Society for Sexual Medicine.

Based on the randomised Euro-EWING99-R1 trial, vincristine, adriamycin, cyclophosphamide (VAC) may be able to replace vincristine, adriamycin, ifosfamide (VAI) in the treatment of standard-risk Ewing sarcoma. However some heterogeneity of treatment effect by gender was observed. The current exploratory study aimed at investigating the influence of gender on treatment efficacy and acute toxicity. Impact of gender on event-free survival (EFS), acute toxicity by course, switches between treatment arms and cumulative dose of alkylating agents was evaluated in multivariable models adjusted for age including terms to test for heterogeneity of treatment effect by gender. The analysis of the EFS was performed on the intention-to-treat population. EFS did not significantly differ between the 509 males and 347 females (p=0.33), but an interaction in terms of efficacy was suspected between treatment and gender (p=0.058): VAC was associated with poorer EFS than VAI in males, hazard ratio (HR) (VAC/VAI)=1.37 [95% confidence interval (CI), 0.98-1.90], contrasting with HR=0.81 [95%CI, 0.53-1.24] in females. Severe toxicity was more frequent in females, whatever the toxicity type. Thirty patients switched from VAI to VAC (9/251 males, 4%, and 21/174 females, 12%) mostly due to renal toxicity, and three from VAC to VAI (2/258 males, 0.8%, and 1/173 females, 0.6%). A reduction of alkylating agent cumulative dose >20% was more frequent in females (15% versus 9%, p=0.005), with no major difference between VAC and VAI (10% versus 13%, p=0.15). Differences of acute toxicity rate and cumulative doses of alkylating agents could not explain the marginal interaction observed in the Euro-EWING99-R1 trial data. Effects of gender-dependent polymorphism/activity of metabolic enzymes (e.g. known for CYP2B6) of ifosfamide versus cyclophosphamide should be explored. External data are required to further evaluate whether there is heterogeneity of alkylating agent effect by gender. NCT00987636 and EudraCT 2008-003658-13. Copyright © 2015 Elsevier Ltd.

This research investigates the influence that gender, single-sex and co-educational schooling can have on students' mathematics education in second-level Irish classrooms. Although gender differences in mathematics education have been the subject of research for many years, recent results from PISA (Programme for International Student Assessment) show that there are still marked differences between the achievement and attitude of male and female students in Irish mathematics classrooms. This paper examines the influence of gender in more detail and also investigates the impact of single-sex or co-educational schooling. This is a follow on study which further analyses data collected by the authors when they designed a pedagogical framework and used this to develop, implement and evaluate a teaching intervention in four second-level Irish schools. The aim of this pedagogical framework was to promote student interest in the topic of algebra through effective teaching of the domain. This paper further analyses the quantitative data collected and investigates whether there were differences in students' enjoyment and achievement scores based on their gender and whether they attended single-sex or co-educational schools.
Psychological outcomes and gender-related development in complete androgen insensitivity syndrome.

Hines, Melissa; Ahmed, S Faisal; Hughes, Ieuan A

2003-04-01

We evaluated psychological outcomes and gender development in 22 women with complete androgen insensitivity syndrome (CAIS). Participants were recruited through a medical database (n = 10) or through a patient support group (n = 12). Controls included 14 males and 33 females, of whom 22 were matched to women with CAIS for age, race, and sex-of-rearing. Outcome measures included quality of life (self-esteem and psychological general well-being), gender-related psychological characteristics (gender identity, sexual orientation, and gender role behavior in childhood and adulthood), marital status, personality traits that show sex differences, and hand preferences. Women recruited through the database versus the support group did not differ systematically, and there were no statistically significant differences between the 22 women with CAIS and the matched controls for any psychological outcome. These findings argue against the need for two X chromosomes or ovaries to determine feminine-typical psychological development in humans and reinforce the important role of the androgen receptor in influencing masculine-typical psychological development. They also suggest that psychological outcomes in women with CAIS are similar to those in other women. However, additional attention to more detailed aspects of psychological well-being in CAIS is needed.

OBJECTIVE To identify gender differences in social support dimensions’ effect on adults’ leisure-time physical activity maintenance, type, and time. METHODS Longitudinal study of 1,278 non-faculty public employees at a university in Rio de Janeiro, RJ, Southeastern Brazil. Physical activity was evaluated using a dichotomous question with a two-week reference period, and further questions concerning leisure-time physical activity type (individual or group) and time spent on the activity. Social support was measured with the Medical Outcomes Study Social Support Scale. For the analysis, logistic regression models were adjusted separately by gender. RESULTS A multinomial logistic regression showed an association between material support and individual activities among women (OR = 2.76; 95%CI 1.2;6.5). Affective support was associated with time spent on leisure-time physical activity only among men (OR = 1.80; 95%CI 1.1;3.2). CONCLUSIONS All dimensions of social support that were examined influenced either the type of, or the time spent on, leisure-time physical activity. In some social support dimensions, the associations detected varied by gender. Future studies should attempt to elucidate the mechanisms involved in these gender differences. PMID:25210819
Gender and Racial/Ethnic Differences in Body Image Development Among College Students

In the present study we used longitudinal methods to examine body image development during the early part of college. Students (N = 390; 54% female) who identified as African American (32%), Latino/a American (27%), and European American (41%) completed surveys during their first, second, and third semesters at college. There were overall gender and racial/ethnic differences in all three aspects of body image, and both stability and change in body image development. Female students’ appearance evaluation became more positive, whereas male students’ appearance evaluation showed no significant change. Individuals’ body areas satisfaction increased over time, but remained stable when controlling for BMI. Appearance orientation did not change, and there were no racial/ethnic differences in body image development. Experiences in the college environment may play a role in these trends. PMID:21983339

This study evaluated the effect of gender mix (the gender combinations of twin pairs) on fetal growth and length of gestation, and reviewed the literature on the long-term effects of this altered fetal milieu on cancer risk. In singletons, it is well established that females weigh less than males at all gestations, averaging 125-135 g less at full term. This gender difference is generally believed to be the result of the effect of androgens on fetal growth. The gender difference in fetal growth is greater before the third trimester and less towards term, with males growing not only more, but also earlier than females. Plurality is a known risk factor for reduced fetal growth and birthweight. Compared with singletons, the mean birthweight percentiles of twins fall substantially (by 10% or more) below the singleton 10th percentile by 28 weeks, below the singleton 50th percentile by 30 weeks, and below the singleton 90th percentile by 34 weeks. In unlike-gender twin pairs, it has been reported that the female prolongs gestation for her brother, resulting in a higher birthweight for the male twin than that of like-gender male twins. Other researchers have demonstrated that females in unlike-gender pairs had higher birthweights than females in like-gender pairs. Analyses from our consortium on 2491 twin pregnancies with known chorionicity showed longer gestations and faster rates of fetal growth in both males and females in unlike-gender pairs compared with like-gender male or female pairs, although these differences were not statistically significant. The post-natal effects for females growing in an androgenic-anabolic environment include increased sensation-seeking behaviour and aggression, lowered visual acuity, more masculine attitudes and masculinising effects of the auditory system and craniofacial growth. In contrast, there is no evidence to suggest that there might be a similar feminising effect on males from unlike-gender pairs. This hormonal exposure in utero may influence adult body size and susceptability to breast cancer.

This study assessed girls’ and boys’ dominance-related behaviors (aggressive, commanding, submissive, and neutral behaviors) as they naturally occurred during interactions with male and female peers and evaluated the possibility that such behaviors elicit aggression from peers. Using a focal observational procedure, young girls’ and boys’ (N = 170; 54% boys) naturally occurring dominance-related behaviors and male and female peers’ aggressive responses to those behaviors were recorded multiple times each week across the academic year. Findings suggested that same-gender aggression occurred at similar rates as other-gender aggression once tendencies toward gender segregated play were controlled. Additionally, there were both gender-based similarities and differences in children’s use of dominance-related behaviors in peer interactions and as antecedents for peers’ aggression. The findings have implications for the literatures on aggression and gendered peer interactions. PMID:22369337

Multiple differences between males and females are reported both in physiological and pathophysiological conditions. To test the hypothesis that gender could influence the motor and cognitive development in children with cerebral palsy (CP). Prospective, cross-sectional. One hundred seventy one children with CP (98 males and 73 females) were evaluated for motor (Gross Motor Function Measure, Gross Motor Function Classification System) and cognitive (Bayley II, Wechsler Scales) functions. Eighty-four of them were assessed before and other eighty-seven children after 4 years of age. No gender-related differences were observed in children with diplegia or quadriplegia, both for motor and cognitive functions. On the contrary, females with hemiplegia scored significantly better (P < 0.01) in cognitive functions and in the dimension D (standing) of the Gross Motor Function Measure, under the age of 4 years. These differences were not observed after this age. In this study we point out that gender might influence differently the psycho-motor development of children with hemiplegia and of those with a more severe clinical involvement as diplegia and quadriplegia. © 2010 European Paediatric Neurology Society.

Individuals that combine features of both genders–gender blends–are sometimes appealing and sometimes not. Heretofore, this difference was explained entirely in terms of sexual selection. In contrast, we propose that part of individuals’ preference for gender blends is due to the cognitive effort required to classify them, and that such effort depends on the context in which a blend is judged. In two studies, participants judged the attractiveness of male-female morphs. Participants did so after classifying each face in terms of its gender, which was selectively more effortful for gender blends, or classifying faces on a gender-irrelevant dimension, which was equally effortful for gender blends. In both studies, gender blends were disliked when, and only when, the faces were first classified by gender, despite an overall preference for feminine features in all conditions. Critically, the preferences were mediated by the effort of stimulus classification. The results suggest that the variation in attractiveness of gender-ambiguous faces may derive from context-dependent requirements to determine gender membership. More generally, the results show that the difficulty of resolving social category membership–not just attitudes toward a social category–feed into perceivers’ overall evaluations toward category members.

To develop and assess the reliability and precision of knee internal/external rotation (IR/ER) threshold to detect passive motion (TTDPM) and determine if gender differences exist. Test-retest for the reliability/precision and cross-sectional for gender comparisons. University neuromuscular and human performance research laboratory. Ten subjects for the reliability and precision aim. Twenty subjects (10 males and 10 females) for gender comparisons. All TTDPM tests were performed using a multi-mode dynamometer. Subjects performed TTDPM at two knee positions (near IR or ER end-range). Intraclass correlation coefficient (ICC (3,k)) and standard error of measurement (SEM) were used to evaluate the reliability and precision. Independent t-tests were used to compare genders. TTDPM toward IR and ER at two knee positions. Intrasession and intersession reliability and precision were good (ICC=0.68-0.86; SEM=0.22°-0.37°). Females had significantly diminished TTDPM toward IR at IR-test position (males: 0.77°±0.14°, females: 1.18°±0.46°, p=0.021) and TTDPM toward IR at the ER-test position (males: 0.87°±0.13°, females: 1.36°±0.58°, p=0.026). No other significant gender differences were found (p>0.05). The current IR/ER TTDPM methods are reliable and accurate for the test-retest or cross-section research design. Gender differences were found toward IR where the ACL acts as the secondary restraint. Copyright © 2011 Elsevier Ltd. All rights reserved.
Gender roles, illness orientation and use of medical services.

Hibbard, J H; Pope, C R

The study investigates illness orientation as a factor which may account for sex differences in the utilization of medical care. First, sex differences in the way symptoms are perceived, evaluated and acted upon (illness orientation) are analyzed. Then gender role factors which may account for sex differences in illness orientation are examined. Finally, the degree to which gender role factors and illness orientation account for sex differences in medical care utilization are assessed. The study population includes 1648 adults between the ages of 18 and 59. Medical record data covering 7 years of outpatient services are linked with survey data on the respondents. The findings show that while females are more likely to perceive symptoms than males, there is no apparent sex difference in a tendency to adopt the sick role when ill. In addition, results indicate that gender role factors such as level and type of role responsibility and concern with health are related to female though not male symptom reports. Illness orientation variables are related to rates of medical utilization for both sexes. However, it is primarily the perception of symptoms and an interest and concern with health which contributes to sex differences in utilization rates. When examining respondents who report either a very low or very high number of symptoms, sex differences in utilization rates fall below statistical significance.

The main aim of this study was to investigate the gender differences in defense mechanisms, ways of coping with stress and identity formation in relation to adolescent suicidal behavior. This study involved 64 adolescents between 12-17 years of age, who were admitted to the emergency service with a suicide attempt. They were evaluated with a semi-structured clinical interview (K-SADS), Ways of Coping Inventory (WCI), Defense Mechanisms Inventory (DMI) and Sense of Identity Assessment Form (SIAF). 60.9% (n = 39) of the adolescents were female, and 39.1% (n=25) were male. There were no statistically significant differences between the girls and the boys with respect to the clinical characteristics of the suicide attempt and the rate of psychiatric disorders. Of the 64 adolescents with suicide attempt, 47 (73.4%) had at least one, and 26 (40.6%) had more than one psychiatric disorder according to K-SADS. Disruptive behavior disorders were more frequent in males, whereas depression was more frequent in girls. The data indicated the importance of identity confusion, major depression and ADHD in adolescents with suicide attempt in both genders. 43.6% (n=17) of the girls and 36% (n=9) of the boys obtained scores higher than the cut-off point of SIAF indicating identity confusion. Professional help seeking and NSSI behaviors before the suicide attempt were more common in adolescents with identity confusion. While there were differences between genders with respect to the defense mechanisms used, no significant difference was found in terms of ways of coping. Evaluation of DMI scores revealed that the turning against object subscale score was significantly higher in boys compared to girls. While evaluating the adolescents at risk, their defense mechanisms, way of coping and sense of identity, as well as their psychiatric diagnosis should be assessed in detail in order to identify the suicidal thoughts and prevent possible suicide attempts.
Gender, multiple roles, role meaning, and mental health.

This paper examines gender differences in the consequences of combining spouse, parent, and worker roles for mental health. I suggest that work and family roles have different meanings for males and females, and that differences in the meaning of these roles may be partially responsible for why the mental health advantages of holding multiple roles are fewer for women than for men. Based on qualitative analyses of follow-up, in-depth interviews with 40 employed married parents who participated in a community panel study of mental health, I find that sex differences in the perceived relationship between work and family roles may help account for sex differences in distress by contributing to male-female differences in both the extent and nature of work-parent conflicts, attributions of responsibility for marital problems, feelings of guilt, and self-evaluations as parents and spouses. By identifying gender differences in the meaning of roles among individuals who have the same multiple role configuration, and suggesting how these differences can help explain sex differences in well-being; this research may expand existing theories about the mental health consequences of multiple role involvements.

Multiple level neurocognitive processes are involved in face processing in humans. The present study examined whether the early face processing such as structural encoding is modulated by task demands that manipulate attention to perceptual or social features of faces and such an effect, if any, is different between men and women. Event-related brain potentials were recorded from male and female adults while they identified a low-level perceptual feature of faces (i.e., face orientation) and a high-level social feature of faces (i.e., gender). We found that task demands that required the processing of face orientations or face gender resulted in modulations of both the early occipital/temporal negativity (N170) and the late central/parietal positivity (P3). The N170 amplitude was smaller in the gender relative to the orientation identification task whereas the P3 amplitude was larger in the gender identification task relative to the orientation identification task. In addition, these effects were much stronger in women than in men. Our findings suggest that attention to social information in faces such as gender modulates both the early encoding of facial structures and late evaluative process of faces to a greater degree in women than in men.
Trends in gender segregation in the choice of science and engineering majors.

Mann, Allison; Diprete, Thomas A

2013-11-01

Numerous theories have been put forward for the high and continuing levels of gender segregation in science, technology, engineering, and mathematics (STEM) fields, but research has not systematically examined the extent to which these theories for the gender gap are consistent with actual trends. Using both administrative data and four separate longitudinal studies sponsored by the U.S. Department of Education's National Center for Education Statistics (NCES), we evaluate several prominent explanations for the persisting gender gap in STEM fields related to mathematics performance and background and general life goals, and find that none of them are empirically satisfactory. Instead, we suggest that the structure of majors and their linkages to professional training and careers may combine with gender differences in educational goals to influence the persisting gender gap in STEM fields. An analysis of gendered career aspirations, course-taking patterns, and pathways to medical and law school supports this explanation. Copyright © 2013 Elsevier Inc. All rights reserved.

This descriptive study was aimed to evaluate the attitudes of the engaged men and women who are of legal age to marry towards gender roles and acceptance of couple violence, and determine their sexual/reproductive health education needs. It was conducted in two marriage registry offices in Ankara, Turkey. The study sample consisted of 740 participants. Data were collected by using semi-structured form, Gender Roles Attitude Scale and Acceptance of Couple Violence Scale. It was found that the engaged couples had educational needs concerning sexual/reproductive health; socio-demographic characteristics such as gender, age, education, residence, and income level created significant differences in the attitudes related to accepting gender roles and violence; and having an egalitarian attitude towards gender roles decreased the rate of accepting violence between the couples. Results indicate that premarital counseling is a promising strategy to support engaged couples' sexual/reproductive health needs, and increase their awareness about gender based couple violence in communities.
Gender-affirming Surgeries in the Era of Insurance Coverage: Developing a Framework for Psychosocial Support and Care Navigation in the Perioperative Period.

2016-01-01

Transgender people have a gender identity different from their birth-assigned sex. Transgender people may seek gender-affirming surgeries to align their body with their identified gender. With increasing visibility of transgender identities, and recognition of the importance of gender-affirming care, has come a policy shift toward mandated coverage or provision of blanket exclusions of these procedures by insurance companies and Medicaid. The World Professional Association for Transgender Health provides guidance to mental health professionals evaluating patients for gender-affirming surgeries, including making a diagnosis and assessing for capacity to consent. However the expansion of covered gender-affirming surgeries to safety-net populations has highlighted the need for an expanded presurgical process which includes a psychosocial assessment and care navigation. The proposed framework expands the preoperative assessment to include these components, and can be used to guide both health systems and insurance providers in the development of transgender medicine programs.

Gender inequality harms the health of millions of women and girls in all over the world. This study aimed to identify the state of gender equity in the health sector of the Islamic Republic of Iran. This study was based on the secondary analysis of the available data in four provinces. The research team held three sessions to select the appropriate indicators for measuring gender equity in Iran. Moreover, using the data of different sources, the indexes were evaluated by applying the brain storming method. To demonstrate the difference between females and males, the ratio of females to males was measured in each indicator. The confidence intervals were used to show significant differences in the gap between men and women. Educational indicators were analyzed using the appraisal framework of UNESCO and International Institute for Education Planning. Findings revealed gender equality in the indicators of education and under-five underweight in all the provinces. However, the indicator of information on the mild psychological diseases showed inequality in favor of males. Infants' mortality, under-five mortality, crude death, drug abuse and smoking showed inequality in favor of females in all the four provinces. The incidence of tuberculosis, severe psychological diseases, and basic and supplementary insurance coverage was equal in all provinces except Tehran. This study revealed gender inequality in many indicators among the provinces. Therefore, improving this condition requires policymaking, planning, and conducting appropriate strategies with proper gender approaches.

The influence of gestational age and gender in the neurodevelopment of infants during the first year of age is not yet fully elucidated. The purpose of this study was to identify the early occurrence of neurodevelopmental differences, between very preterm, late preterm and term born infants and the possible influence of the gender on the neurodevelopment in early infancy. A total of 188 low-risk infants, 69 very preterms, 71 late-preterms, and 48 term infants were assessed at 3, 6, 9, 12 months corrected age using the Hammersmith Infant Neurological Examination (HINE). At two years of age infants performed the Mental Developmental Index (MDI) of the Bayley Scales of Infant Development. The main results indicate that both very preterms and late-preterms showed significant lower global scores than term born infants at each evaluation (p < 0.001) at HINE and namely, at 3 months for the subsections "cranial nerve" and "posture" and at every age for "tone"; no gender differences has been evidenced in neurological performances. At the MDI, very preterms showed significant lower scores (p < 0.01) than both late-preterm and term born infants; gender differences were observed for preterms only (very and late), with best performances for females. Our results point out the presence of gestational age and gender-dependent differences in the development of infants assessed during the first 2 years of life.

In this study, male and female participants were exposed to identical news stories covering obesity topics paired with tweets from Twitter users. Our study aimed at understanding how obesity-related news combined with user-generated social media posts (i.e., tweets) affect consumers' evaluations of online content and viral behavioral intentions (the intentions to like, share, and comment). An experiment (N = 316) explored how gender and weight of a Twitter user (tweeter) affect participants' evaluations and viral behavioral intentions toward news stories. Participants differed in their evaluations of and viral behavioral intentions for news stories as a function of Twitter users' gender and weight, as well as participants' gender. While participants expressed more favorable attitudes toward news stories paired with tweets by overweight than healthy females (with the opposite true for tweets by male users), participants expressed greater viral behavioral intentions for news stories paired with tweets by healthy weight than overweight user. These effects were more pronounced among male than female participants. Findings are discussed within the context of social media posts and their persuasive effects in relation to attitude and behavior changes.

A barrier to monitoring the health of gender minority (transgender) populations is the lack of brief, validated tools with which to identify participants in surveillance systems. We used the Growing Up Today Study (GUTS), a prospective cohort study of U.S. young adults (mean age = 20.7 years in 2005), to assess the validity of self-report measures and implement a two-step method to measure gender minority status (step 1: assigned sex at birth, step 2: current gender identity). A mixed-methods study was conducted in 2013. Construct validity was evaluated in secondary data analysis of the 2010 wave (n = 7,831). Cognitive testing interviews of close-ended measures were conducted with a subsample of participants (n = 39). Compared to cisgender (non-transgender) participants, transgender participants had higher levels of recalled childhood gender nonconformity age < 11 years and current socially assigned gender nonconformity and were more likely to have ever identified as not completely heterosexual (p < 0.001). No problems with item comprehension were found for cisgender or gender minority participants. Assigned sex at birth was interpreted as sex designated on a birth certificate; transgender was understood to be a difference between a person's natal sex and gender identity. Participants were correctly classified as male, female, or transgender. The survey items performed well in this sample and are recommended for further evaluation in languages other than English and with diverse samples in terms of age, race/ethnicity, and socioeconomic status.

Although "qi, blood, and fluid" (QBF) is the most important concept for patients in Kampo medicine, there are few studies about the conditions of the QBF system among healthy populations. We used QBF pattern scores to determine whether or not medical students, presumed to be healthy, had any potentially pathological conditions. Six consecutive fourth-year classes totaling 652 medical students evaluated their own QBF conditions using Terasawa's QBF pattern scores. The six conditions: "qi deficiency" (QD), "qi stagnation" (QS), "qi counterflow" (QC), "blood deficiency" (BD), "blood stasis" (BS), and "fluid disturbance" (FD), were categorized according to Terasawa's criteria. The Mann-Whitney U test was used to compare the score differences between the genders, Chi-square test was used to examine gender differences in the QBF diagnoses, and the Spearman's rank-order correlation coefficient analysis was used to analyze the correlation between each category of QBF. In all, 44.6% of the students met at least one diagnostic criterion in the QBF system. QC, BD, BS, and FD were established more in females, and QD and QS were established without gender differences. Most students who were presumed to be healthy were revealed to have some potentially pathological conditions using the QBF system.

Burn injury can be debilitating and affect survivors' quality of life in a profound fashion. Burn injury may also lead to serious psychosocial challenges that have not been adequately studied and addressed. Specifically, there has been limited research into the associations of burn injury on community reintegration based on gender. This work analyzed data from 601 burn survivors who completed field testing of a new measure of social participation for burn survivors, the Life Impact Burn Recovery Evaluation (LIBRE) Profile. Differences in item responses between men and women were examined. Scores on the six LIBRE Profile scales were then compared between men and women using analysis of variance and adjusted linear multivariate regression modeling. Overall, men scored significantly better than women on four of the six LIBRE Profile scales: Sexual Relationships, Social Interactions, Work & Employment, and Romantic Relationships. Differences were not substantially reduced after adjustment for demographic characteristics and burn size. Men scored better than women in most of the areas measured by the LIBRE Profile. These gender differences are potentially important for managing burn patients during the post-injury recovery period.

Depression is associated with substantial personal suffering and reduced quality of life and functioning. The aim of this study was to investigate gender differences on quality of life and functional impairment of outpatients with depression after acute phase treatment. 1503 depression outpatients were recruited from eleven hospitals in China. Subjects were evaluated with sociodemographic characteristics, history and self-report instruments, related to severity of symptoms, function and quality of life. All data were analyzed to determine the gender differences. Men had a younger age at onset and the first onset age, higher education compared to women in total patients and with or without residual symptoms group. Using regression analysis, it was found that gender was significantly statistically related to severity scores of SDS and had no correlation with Q-LES-Q-SF total scores. In the residual symptoms group, greater functional impairment was noted by men in the area of work and social life. Significant gender differences of mood, work and sexual life in quality of life were observed. This is a cross-sectional study of depressed outpatients and duration of acute phase treatment may not an adequate time to measure changes. Depression appears to affect men more seriously than women after acute phase treatment. Men had a younger age at onset and the first onset age, higher education, more functional impairment and lower satisfaction of quality of life in mood, work and sexual life. Gender differences affect acute treatment, remission and recovery. Copyright © 2017 Elsevier B.V. All rights reserved.
Gender differences in drug abuse in the forensic toxicological approach.

Gender differences in substance use/abuse have been the focus of research in the last 15 years. Initiation, use patterns, acceleration of disease course, and help-seeking patterns are known to be influenced by gender differences with regard to biological, psychological, cultural and socioeconomic factors. This paper presents a systematic review of published data on gender differences in the use/abuse of psychoactive and psychotic drugs, focusing on the importance of a multidisciplinary approach. The basis for this paper was obtained by Medline searches using the search terms "human" and "gender", combined with individual drug names or "drugs of abuse". The reference lists of these papers were further checked for other relevant studies. The gender difference in drug abuse is more evident in adults than in adolescents (13-19 years): adult men are 2-3 times more likely than women to develop drug abuse/dependence disorders and approximately 4 times as likely to have an alcohol use disorder. Such prevalence rates have not been observed in adolescents. Differences between men and women involve: (i) the biological response to the drug, (ii) the progression to drug dependence, and (iii) the comorbid psychiatric diagnoses, which may be due to both sociocultural factors and innate biological differences. A crucial role played by ovarian hormones (oestrogens and progesterone) has been documented in both human and animal model studies. Epidemiological data on how particular psychobiological and physiological characteristics in females influence vulnerability to both drug addiction and toxicological consequences of drugs are still in their infancy. Significant gaps remain in our knowledge, which are primarily attributable to the lack of empirical data that only a systematic and multidisciplinary approach to the topic can generate. The introduction of gender into forensic toxicological evaluations may help elucidate the relationship between the body's absorption of abused drugs (alone or in combination) and the onset of intoxications, both lethal and none.

Paracoccidioidomycosis is a neglected tropical fungal infection with great predilection for adult men, indicating the participation of female hormone estrogen in preventing paracoccidioidomycosis development in women. Estrogen has an immunologic effect leading to polarization toward the Th2 immune response, which favors the disease evolution. To evaluate estrogen and progesterone receptors in oral paracoccidioidomycosis lesions and to verify any association with tissue fungi counting in women and men. Thirty-two cases of chronic oral paracoccidioidomycosis were included. Immunohistochemical analyses for anti-estrogen receptor-α, anti-progesterone receptor and anti-Paracoccidioides brasiliensis antibodies were performed. The differences between women and men and the relations among the immunomarkers for each gender were also evaluated. A significant positive correlation was observed between estrogen receptor-α and the amount of fungi in women. In addition, estrogen receptor-α was mildly expressed in the inflammatory cells of female patients, while progesterone receptor was expressed in both genders, with similar expression between women and men. Moreover, fungi counting revealed no differences between genders. Estrogen receptor-α was expressed only in women and showed a positive correlation with the amount of fungi in oral paracoccidioidomycosis, while progesterone receptor was observed in both genders and exhibited no correlation with estrogen receptor-α or fungi counting.
Race and gender moderation of the relationship between cessation beliefs and intentions: is race or gender message segmentation necessary in anti-smoking campaigns?

Debate persists over whether different message strategies in anti-smoking campaigns are needed for audiences of different races or genders. This study considers the need for ‘message segmentation’, which is the process of differentiating the beliefs that might be the focus of messages for population subgroups. We have two aims: (i) lay out an approach that yields evidence about the necessity for message segmentation and (ii) demonstrate and assess findings from this approach using the formative evaluation for the Philadelphia Anti-Smoking Campaign. We examine whether associations between beliefs about quitting smoking and intention to quit are moderated by race (black/white) or gender. Data came from a representative sample of 501 adult smokers (46% black; 56% female) surveyed in July 2010 for the campaign’s formative evaluation. Out of 26 beliefs about cessation, 8 were significantly related to cessation intention regardless of subgroup affiliation, suggesting that these would be promising beliefs for messages in a unified campaign. Four beliefs were significant for white smokers only, and three beliefs were significant for female smokers only. The evidence justified a unified message approach because subgroups shared enough beliefs that could become message strategies to increase cessation across smokers without the added costs associated with message segmentation.

Investigation sought to determine whether there is any acoustic variable to objectively differentiate gender in children with normal voices. A total of 30 children, 15 boys and 15 girls, with perceptually normal voices were examined. They were between 7 and 10 years old (mean: 8.1, SD: 0.7 years). Subjects were required to perform the following phonatory tasks: (1) to phonate sustained vowels [a:], [i:], [u:], (2) to read a phonetically balanced text, and (3) to sing a song. Acoustic analysis included long-term average spectrum (LTAS), fundamental frequency (F0), speaking fundamental frequency (SFF), equivalent continuous sound level (Leq), linear predictive code (LPC) to obtain formant frequencies, perturbation measures, harmonic to noise ratio (HNR), and Cepstral peak prominence (CPP). Auditory perceptual analysis was performed by four blinded judges to determine gender. No significant gender-related differences were found for most acoustic variables. Perceptual assessment showed good intra and inter rater reliability for gender. Cepstrum for [a:], alpha ratio in text, shimmer for [i:], F3 in [a:], and F3 in [i:], were the parameters that composed the multivariate logistic regression model to best differentiate male and female children's voices. Since perceptual assessment reliably detected gender, it is likely that other acoustic markers (not evaluated in the present study) are able to make clearer gender differences. For example, gender-specific patterns of intonation may be a more accurate feature for differentiating gender in children's voices. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.
Men ask more questions than women at a scientific conference

Gender inequity in science and academia, especially in senior positions, is a recognised problem. The reasons are poorly understood, but include the persistence of historical gender ratios, discrimination and other factors, including gender-based behavioural differences. We studied participation in a professional context by observing question-asking behaviour at a large international conference with a clear equality code of conduct that prohibited any form of discrimination. Accounting for audience gender ratio, male attendees asked 1.8 questions for each question asked by a female attendee. Amongst only younger researchers, male attendees also asked 1.8 questions per female question, suggesting the pattern cannot be attributed to the temporary problem of demographic inertia. We link our findings to the ‘chilly’ climate for women in STEM, including wider experiences of discrimination likely encountered by women throughout their education and careers. We call for a broader and coordinated approach to understanding and addressing the barriers to women and other under-represented groups. We encourage the scientific community to recognise the context in which these gender differences occur, and evaluate and develop methods to support full participation from all attendees.

When researchers find an association between two variables, it is useful to evaluate the role of other constructs in this association. While assessing these mediation effects, it is important to determine if results are equal for different groups. It is possible that the strength of a mediation effect may differ for males and females, for example - such an effect is known as moderated mediation. Participants were 2532 adolescents from diverse ethnic/racial backgrounds and equally distributed across gender. The goal of this study was to investigate parental respect as a potential mediator of the relationship between gender and delinquency and mental health, and to determine whether observed mediation is moderated by gender. Parental respect mediated the association between gender and both delinquency and mental health. Specifically, parental respect was a protective factor against delinquency and mental health problems for both females and males. Demonstrated the process of estimating models in Lavaan, using two approaches (i.e. single group regression and multiple group regression model), and including covariates in both models.

Using Gender Schema Theory to Examine Gender Equity in Computing: a Preliminary Study

NASA Astrophysics Data System (ADS)

Agosto, Denise E.

Women continue to constitute a minority of computer science majors in the United States and Canada. One possible contributing factor is that most Web sites, CD-ROMs, and other digital resources do not reflect girls' design and content preferences. This article describes a pilot study that considered whether gender schema theory can serve as a framework for investigating girls' Web site design and content preferences. Eleven 14- and 15-year-old girls participated in the study. The methodology included the administration of the Children's Sex-Role Inventory (CSRI), Web-surfing sessions, interviews, and data analysis using iterative pattern coding. On the basis of their CSRI scores, the participants were divided into feminine-high (FH) and masculine-high (MH) groups. Data analysis uncovered significant differences in the criteria the groups used to evaluate Web sites. The FH group favored evaluation criteria relating to graphic and multimedia design, whereas the MH group favored evaluation criteria relating to subject content. Models of the two groups' evaluation criteria are presented, and the implications of the findings are discussed.
Rethinking stereotype reliance. Understanding the connection between female candidates and gender stereotypes.

Bauer, Nichole M

2013-01-01

Increasing numbers of female candidates are running for Congress in American national elections. Despite the rise in female candidates running for office, women are not significantly increasing their presence in the House and Senate. A much hypothesized influence over the electoral fates of female candidates is the role of gender stereotypes. However, political science scholars have struggled to pinpoint the effect of stereotypes on vote choice, if there is any effect. This essay compares the way social psychology and political science scholars theoretically, conceptually and empirically test for gender stereotype influence over evaluations of female candidates and politicians. Differences emerge in the theoretical assumptions made in the two disciplines, the types of measures used in research, and the empirical tests conducted to demonstrate the presence or absence of stereotypes in evaluations of women. The discussion explores how scholars studying female candidates and politicians can integrate insights from social psychology to clarify the role of stereotypes in candidate evaluation and choice.

The orbital aperture is the entrance to the orbit in which most important visual structures such as the eyeball and the optic nerve are found. It is vital not only for the visual system but also for the evaluation and recognition of the face. Eyeball volume is essential for diagnosing microphthalmos or buphthalmos in several eye disorders. Knowing the length of the optic nerve is necessary in selecting the right instruments for enucleation. Therefore, the aim of this study was to evaluate eyeball volume, orbital aperture, and optic nerve dimensions for a morphological description in a Turkish population sample according to gender and body side.Paranasal sinus computed tomography (CT) scans of 198 individuals (83 females, 115 males) aged between 5 and 74 years were evaluated retrospectively. The dimensions of orbital aperture, axial length and volume of eyeball, and diameter and length of the intraorbital part of the optic nerve were measured. Computed tomography examinations were performed on an Activion 16 CT Scanner (Toshiba Medical Systems, 2008 Japan). The CT measurements were calculated by using OsiriX software on a personal computer. All parameters were evaluated according to gender and right/left sides. A statistically significant difference between genders was found with respect to axial length of eyeball, optic nerve diameter, dimensions of orbital aperture on both sides, and right optic nerve length. Furthermore, certain statistically significant side differences were also found. There were statistically significant correlations between age and the axial length of the eyeball, optic nerve diameter, and the transverse length of the orbital aperture on both sides for the whole study group.In this study we determined certain morphometric parameters of the orbit. These outcomes may be helpful in developing a database to determine normal orbit values for the Turkish population so that quantitative assessment of orbital disease and orbital deformities will be evaluated both for preoperative planning and for assessing postoperative outcomes.
Gender bias in leader evaluations: merging implicit theories and role congruity perspectives.

Hoyt, Crystal L; Burnette, Jeni L

2013-10-01

This research extends our understanding of gender bias in leader evaluations by merging role congruity and implicit theory perspectives. We tested and found support for the prediction that the link between people's attitudes regarding women in authority and their subsequent gender-biased leader evaluations is significantly stronger for entity theorists (those who believe attributes are fixed) relative to incremental theorists (those who believe attributes are malleable). In Study 1, 147 participants evaluated male and female gubernatorial candidates. Results supported predictions, demonstrating that traditional attitudes toward women in authority significantly predicted a pro-male gender bias in leader evaluations (and progressive attitudes predicted a pro-female gender bias) with an especially strong effect for those with more entity-oriented, relative to incrementally oriented person theories. Study 2 (119 participants) replicated these findings and demonstrated the mediating role of these attitudes in linking gender stereotypes and leader role expectations to biased evaluations.

There are differences between the genders in their innate performances on simulation trainers, which may impair accurate assessment of psychomotor skills. The performance of fourth-year students with no exposure to the Minimally Invasive Surgical Trainer compared based on gender, and other psychomotor skills. Our study included 16 male and 16 female students. After adjusting for choice of medical specialty (P<.001), current video game use (P=.6), and experience in the operating room (P=.4), female sex was an independent factor for worse performance (P=.04) in multivariate models. Women took more time than men (P<.01) and made more errors (29 versus 25 on 3 reps, P<.01). Among medical students with no previous exposure to laparoscopic trainers, female students perform worse than male students after adjusting for confounding factors. This difference must be recognized by training programs while using simulators for training and evaluation.
Marriage-Market Constraints and Mate-Selection Behavior: Racial, Ethnic, and Gender Differences in Intermarriage

Choi, Kate H.; Tienda, Marta

2016-01-01

Despite theoretical consensus that marriage markets constrain mate selection behavior, few studies directly evaluate how local marriage market conditions influence intermarriage patterns. Using data from the American Community Survey, we examine what aspects of marriage markets influence mate selection; assess whether the associations between marriage market conditions and intermarriage are uniform by gender and across pan-ethnic groups; and investigate the extent to which marriage market conditions account for group differences in intermarriage patterns. Relative group size is the most salient and consistent determinant of intermarriage patterns across pan-ethnic groups and by gender. Marriage market constraints typically explain a larger share of pan-ethnic differences in intermarriage rates than individual traits, suggesting that scarcity of co-ethnic partners is a key reason behind decisions to intermarry. When faced with market constraints, men are more willing or more successful than women in crossing racial and ethnic boundaries in marriage. PMID:28579638
Models with Men and Women: Representing Gender in Dynamic Modeling of Social Systems.

Palmer, Erika; Wilson, Benedicte

2018-04-01

Dynamic engineering models have yet to be evaluated in the context of feminist engineering ethics. Decision-making concerning gender in dynamic modeling design is a gender and ethical issue that is important to address regardless of the system in which the dynamic modeling is applied. There are many dynamic modeling tools that operationally include the female population, however, there is an important distinction between females and women; it is the difference between biological sex and the social construct of gender, which is fluid and changes over time and geography. The ethical oversight in failing to represent or misrepresenting gender in model design when it is relevant to the model purpose can have implications for model validity and policy model development. This paper highlights this gender issue in the context of feminist engineering ethics using a dynamic population model. Women are often represented in this type of model only in their biological capacity, while lacking their gender identity. This illustrative example also highlights how language, including the naming of variables and communication with decision-makers, plays a role in this gender issue.
Women's mental health research: the emergence of a biomedical field.

PubMed

Blehar, Mary C

2006-01-01

This review surveys the field of women's mental health, with particular emphasis on its evolution into a distinct area of biomedical research. The field employs a biomedical disease model but it also emphasizes social and cultural influences on health outcomes. In recent years, its scope has expanded beyond studies of disorders occurring in women at times of reproductive transitions and it now encompasses a broader study of sex and gender differences. Historical and conceptual influences on the field are discussed. The review also surveys gender differences in the prevalence and clinical manifestations of mental disorders. Epidemiological findings have provided a rich resource for theory development, but without research tools to test theories adequately, findings of gender differences have begged the question of their biological, social, and cultural origins. Clinical depression is used to exemplify the usefulness of a sex/gender perspective in understanding mental illness; and major theories proposed to account for gender differences are critically evaluated. The National Institutes of Health (NIH) is the primary federal funding source for biomedical women's mental health research. The review surveys areas of emphasis in women's mental health research at the NIH as well as some collaborative activities that represent efforts to translate research findings into the public health and services arenas. As new analytic methods become available, it is anticipated that a more fundamental understanding of the biological and behavioral mechanisms underlying sex and gender differences in mental illness will emerge. Nonetheless, it is also likely that integration of findings predicated on different conceptual models of the nature and causes of mental illness will remain a challenge. These issues are discussed with reference to their impact on the field of women's mental health research.

To evaluate gender differences of initial posters in threads dealing with bladder cancer on an online discussion board. 529 threads opened between 09/2005 and 03/2012 were screened on the largest German speaking bladder cancer online discussion board. 366 threads fulfilled the requirements for this study. Gender, age, number, status of concern and oncological situation of initiating posters as well as their motives and language style were analyzed following a standardized protocol. Threads were initiated in 45% (164/366) by men and in 55% (202/366) by women. Mean age of male initiating posters was 50 years and of female posters 44 years (p < 0.001). Of males 80% (132/164) were concerned patients and 20% (32/164) relatives or friends. Of females they were 39% (78/202) and 61% (124/202), respectively (p < 0.001). In general motives for initial posting were focused on medical information and did not differ between both genders. 81% of the posters asked for medical information or therapeutic recommendations regarding diagnosis, treatment and prognosis. However, women significantly more often expressed their wish for emotional support (p = 0.034) and in tendency wanted to share their experiences with others (p = 0.057). Language analysis revealed that women significantly more often used a tentative language style than men (p = 0.003). Even though women are less often affected by bladder cancer, they are more active -especially for their concerned family members - on the evaluated discussion board than men. Whereas both genders equally often ask for medical information, women more often want to share their experiences and look for emotional support.

Few studies about gender differences in job quality and job satisfaction among medical professionals have been carried out in China. So the objectives of this study were to examine whether and to what extent gender differences existed in job quality and job satisfaction of doctors in rural western China. From 2009 to 2011, a total of 1472 doctors from 103 selected county-level health care facilities in rural western China were recruited into the study. Information about the doctors' demographic characteristics, job quality, and job satisfaction was collected through a designed questionnaire. Besides examining gender differences in single dimensions of job quality and job satisfaction, principal component analysis was used to construct a composite job quality index to measure the differences in the comprehensive job quality, and exploratory factor analysis was applied to evaluate the differences in the overall job satisfaction. Chi-square test was used to calculate differences between proportions, and t-test was used to compare differences between means. Among the doctors, there were 705 males and 767 females (ratio 1:1.09). Male doctors had significantly higher monthly salaries, longer working hours, more times of night shifts per month, longer continuous working hours, and longer years of service at current facilities, and marginally significantly higher hourly wage and longer years of service in current professions. However, female doctors showed greater overall job qualities. Significant and marginally significant gender differences were only found in satisfaction with remuneration compared to workload, the chance of promotion and working environment. But female showed greater satisfaction in the overall job satisfaction and the factor including sub-aspects of working environment, remuneration compared to workload, the chance of promotion, utilization of subjective initiative, and sense of achievement. Gender differences in job quality and job satisfaction did exist among doctors in rural western China. The participating female doctors were shown to have better job quality and greater job satisfaction.

Methodological issues are pointed to as the main sources of inconsistencies in studies about the association between job strain and blood pressure (BP)/hypertension. Our aim was to analyze the relationship between job strain and the whole BP distribution, as well as potential differences by gender, age, and use of antihypertensives. Additionally, we addressed issues relating to the operationalization of the exposure and outcome variables that influence the study of their inter-relations. We evaluated the baseline date of 12,038 participants enrolled in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) (2008–2010), a multicenter cohort study of 35–74-year-old civil servants. Job strain was assessed by the Demand-Control-Support Questionnaire. The distribution of casual BP by categories of job strain was compared by a combination of exploratory techniques. Participants were classified into three subgroups (normotensives, medicated hypertensives, and unmedicated hypertensives), and analyses were stratified by gender and age. The relationship between job strain and casual BP varied along the whole outcome distribution. Hypertensive participants had greater differences in casual BP by job strain category, especially medicated hypertensives. Differences in casual BP were also greater for systolic than for diastolic BP and for older participants. No differences were encountered by gender. The exclusion of participants susceptible to misclassification for the exposure and outcome variables increased the differences observed between the categories of low and high job strain. In conclusion, the relationship between job strain and casual BP varied along the whole outcome distribution and by use of antihypertensive drugs, age, and BP parameter evaluated. Misclassification for exposure and outcome variables should be considered in analyses of this topic. PMID:28441727

Factors related to sexual arousal are different in men and women. The conditions for women to become aroused are more complex. However, the conventional audio-visual stimulation (AVS) materials used to evaluate sexual arousal are universal. In the present study, we investigated sexual differences in the response to different types of AVS by studying activated areas of the brain using functional magnetic resonance imaging (fMRI). fMRI was performed during two types of AVS in 20 healthy heterosexual volunteers (aged 20-28 years, 10 men and 10 women). The two AVS types were: (1) mood type, erotic video clips with a concrete story and (2) physical type, directly exposing sexual intercourse and genitalia. fMRI images were analyzed and compared for each stimulation with a Mann-Whitney U test, with statistical significance set at P<0.05. Men preferred the physical type of AVS to the mood type (mean arousal score 2.14 vs 1.86 in females) and women preferred the mood type (mean arousal score 2.14 vs 1.86 in males) (P<0.05). Degrees of activation in brain areas differed between genders and types of AVS for each gender. This should be considered when applying the AVS method to evaluate and diagnose female sexual dysfunction.

Previous research has shown that job characteristics, private life and psychosocial factors partially account for gender difference in work absences because of sickness. Most studies have analysed these factors separately. The aim of the present study was to evaluate whether these explanatory factors act as mediators when they are considered simultaneously. The evaluated data set comprises the merger of two Belgian longitudinal studies, BELSTRESS III and SOMSTRESS. It includes 3821 workers (1541 men) aged 21-66 years, employed in eight organizations. A multiple mediation analysis was performed to explain the higher prevalence among women. Estimated factors were occupational grade, total number of paid working hours per week, job strain, overcommitment, home-work interference and social support at and outside work. Prospective data concerning duration and frequency of medically justified sickness absence (registered by the organizations) were used as outcomes. Overall, the mediating factors partially account for gender difference in sickness absence. The strongest mediator for both outcomes is job strain. In addition, difference in absence duration is mediated by social support at work, whereas difference in frequency is mediated by professional grade and home-work interference. Our results call attention to the necessity to elaborate actual preventive actions aiming at favouring a better positioning of women on the labour market in term of hierarchical level as well as in terms of quality of work for reducing sickness absence in this group.

Low back pain (LBP) is a well-known reason people worldwide seek medical help and it is a Leading cause of chronic pain and disability among people of working age. Recent research reveals that the female gender is not only a risk factor for developing LBP but it may also influence the management of this common condition. Our objective was to evaluate gender-related differences in the management of LBP patients in a specialized hospital-based chronic pain unit. A cross-sectional survey was carried out through telephone interviews and the hospital computerized database (N = 129). Socio-demographic, Lifestyle, occupational and medical variables were collected, and their association with the frequency of use of five different diagnostic and/or therapeutic modalities was examined using gender stratification. After adjustment for age, religion, socioeconomic data and the number of co-morbid conditions, women were more prone to poly-pharmacy of analgesic medications prescribed in the previous year compared to men (p = 0.024) and exhibited an increased rate of treatment cessations due to adverse effects (p < 0.001). Interestingly, while women tended to utilize more healthcare services besides the pain clinic (p = 0.097), men tended on average to have more visits than women to the pain clinic for their complaints (p = 0.019). Among those who applied for insurance compensation for LBP-related disability, women exhibited increased use of imaging procedures compared to men (p = 0.038). This cross-sectional study reveals gender-related differences in management and health services utilization for treatment of LBP in the chronic pain clinic. If confirmed in other centers, these findings should inspire gender-sensitive resource management of the treatment of chronic pain patients. Moreover, the findings suggest that increased awareness of gender bias when seeking insurance compensation for LBP-related disability is warranted.

Study Objectives : Nocturnal bruxism is associated with gastroesophageal reflux disease (GERD), and GERD is strongly associated with obstructive sleep apnea (OSA). Gender and ethnic differences in the prevalence and clinical presentation of these often overlapping sleep disorders have not been well documented. Our aim was to examine the associations between, and the symptoms associated with, nocturnal GERD and sleep bruxism in patients with OSA, and to examine the influence of gender and ethnicity. Methods : A retrospective chart review was performed of patients diagnosed with OSA at an academic sleep center. The patients completed a sleep questionnaire prior to undergoing polysomnography. Patients with confirmed OSA were evaluated based on gender and ethnicity. Associations were determined between sleep bruxism and nocturnal GERD, and daytime sleepiness, insomnia, restless legs symptoms, and markers of OSA severity in each group. Results : In these patients with OSA, the prevalence of nocturnal GERD (35%) and sleep bruxism (26%) were higher than the general population. Sleep bruxism was more common in Caucasians than in African Americans or Hispanics; there was no gender difference. Nocturnal GERD was similar among all gender and ethnic groups. Bruxism was associated with nocturnal GERD in females, restless legs symptoms in all subjects and in males, sleepiness in African Americans, and insomnia in Hispanics. Nocturnal GERD was associated with sleepiness in males and African Americans, insomnia in females, and restless legs symptoms in females and in Caucasians. Conclusion : Patients with OSA commonly have comorbid sleep bruxism and nocturnal GERD, which may require separate treatment. Providers should be aware of differences in clinical presentation among different ethnic and gender groups. PMID:25352924

National randomized experiments and validation studies were conducted on 873 tenure-track faculty (439 male, 434 female) from biology, engineering, economics, and psychology at 371 universities/colleges from 50 US states and the District of Columbia. In the main experiment, 363 faculty members evaluated narrative summaries describing hypothetical female and male applicants for tenure-track assistant professorships who shared the same lifestyle (e.g., single without children, married with children). Applicants' profiles were systematically varied to disguise identically rated scholarship; profiles were counterbalanced by gender across faculty to enable between-faculty comparisons of hiring preferences for identically qualified women versus men. Results revealed a 2:1 preference for women by faculty of both genders across both math-intensive and non-math-intensive fields, with the single exception of male economists, who showed no gender preference. Results were replicated using weighted analyses to control for national sample characteristics. In follow-up experiments, 144 faculty evaluated competing applicants with differing lifestyles (e.g., divorced mother vs. married father), and 204 faculty compared same-gender candidates with children, but differing in whether they took 1-y-parental leaves in graduate school. Women preferred divorced mothers to married fathers; men preferred mothers who took leaves to mothers who did not. In two validation studies, 35 engineering faculty provided rankings using full curricula vitae instead of narratives, and 127 faculty rated one applicant rather than choosing from a mixed-gender group; the same preference for women was shown by faculty of both genders. These results suggest it is a propitious time for women launching careers in academic science. Messages to the contrary may discourage women from applying for STEM (science, technology, engineering, mathematics) tenure-track assistant professorships.

Background: The Child and Adolescent Behavior Inventory (CABI) is a questionnaire designed to collect information from the parents of children and adolescents, both for the preparation of screening and epidemiological studies and for clinical evaluation. It has been published in CPEMH in 2013, with the first data on 8-10 years old school children. Here we report an extended standardization on a school population 6-17 years old and the first results of the application in a clinical sample. Methods: Parents, after giving their informed consent, answered to the questionnaire. Complete and reliable data were obtained from the parents of 659 school children and adolescents 6-17 y.o., with a balanced distribution of gender. Moreover, in a population of 84 patients, the results with the CABI were compared with the clinical evaluation and the CBCL. Results: In the school population, scores were different in relation to gender and age. The values of externalizing disorders were higher in males, with the highest values for ADHD in the 6-10 y.o. children. On the contrary, the scores of internalizing disorders and of eating disorders tended to be slightly higher in females. In the clinical population, scores at the CABI were in agreement with the clinical evaluation in 84% cases for depressive symptoms (compared to CBCL 66%), 53% for anxiety symptoms (CBCL 42%) and 87% for ODD (CBCL 69%), differences, however; without statistical significance (chi square). Conclusion: The study obtained normative data for the CABI and gave information of the behavioral differences in relation to age and gender of the school population as evaluated by parents/caregivers. Clinically, the CABI provided useful information for the clinical evaluation of the patient, sometimes with better agreement with the final diagnosis compared to the CBCL. PMID:28458717
Participation in introductory biology laboratories: An integrated assessment based on surveys, behavioral observations, and qualitative interviews

Scope and method of study. The purpose of this study was to evaluate the effect of gender, major, and prior knowledge of and attitude toward biology on participation in introductory biology laboratories. Subjects for this study were 3,527 students enrolled in college-level introductory biology courses. During the study, three introductory courses were replaced with one mixed-majors course. The new course adopted a different pedagological approach from the previous courses in that an inquiry-based approach was used in lectures and laboratories. All subjects completed a survey that measured content knowledge using the NABT/NSTA High School Biology Examination Version 1990 and attitude using Russell and Hollander's Biology Attitude Scale. I used and discuss the merits of using ethological methods and data collection software, EthoScribeTM (Tima Scientific) to collect behavioral data from 145 students. I also evaluated participation using qualitative interviews of 30 students. I analyzed content knowledge and attitude data using ANOVA and Pearson correlation, and behavioral data using Contingency Table Analysis. I analyzed interviews following methods outlined by Rubin and Rubin. Findings. Course style and gender were the most useful variables in distinguishing differences among groups of students with regard to attitude, content knowledge, and participation in laboratories. Attitude toward biology and achievement measured by the surveys were found to be positively correlated; however, gender, major, class standing, course style and interactions between these variables also had effects on these variables. I found a positive association among attitude, achievement and participation in hands-on activities in laboratories. Differences in participation also were associated group type. In a traditional introductory biology course, females in single-gender groups, gender-equal, or groups in which females were the majority spent more time performing hands-on science-related activities than did females in groups in which they were the minority. Conversely, males in mixed-gender groups spent more time performing hands-on activities than did males in single-gender groups. Both sexes participated equally in laboratories taught in an inquiry-based style.

We assessed the relationship between structural characteristics (area) and microstructure (apparent diffusion coefficient; ADC) of the corpus callosum (CC) in 57 healthy children aged 7.0 to 9.1 years, with diverse cognitive and academic abilities as well as executive functions evaluated with a neuropsychological battery for children. The CC was manually delineated and sub-segmented into six regions, and their ADC and area were measured. There were no significant differences between genders in the callosal region area or in ADC. The CC area and ADC, mainly of anterior regions, correlated with different cognitive abilities for each gender. Our results suggest that the relationship between cognitive abilities and CC characteristics is different between girls and boys and between the anterior and posterior regions of the CC. Furthermore, these findings strenghten the idea that regardless of the different interhemispheric connectivity schemes per gender, the results of cognitive tasks are very similar for girls and boys throughout childhood.

Why women apologize more than men: gender differences in thresholds for perceiving offensive behavior.

PubMed

Schumann, Karina; Ross, Michael

2010-11-01

Despite wide acceptance of the stereotype that women apologize more readily than men, there is little systematic evidence to support this stereotype or its supposed bases (e.g., men's fragile egos). We designed two studies to examine whether gender differences in apology behavior exist and, if so, why. In Study 1, participants reported in daily diaries all offenses they committed or experienced and whether an apology had been offered. Women reported offering more apologies than men, but they also reported committing more offenses. There was no gender difference in the proportion of offenses that prompted apologies. This finding suggests that men apologize less frequently than women because they have a higher threshold for what constitutes offensive behavior. In Study 2, we tested this threshold hypothesis by asking participants to evaluate both imaginary and recalled offenses. As predicted, men rated the offenses as less severe than women did. These different ratings of severity predicted both judgments of whether an apology was deserved and actual apology behavior.

An evaluation of a workplace course in England for English for Speakers of Other Language (ESOL) learners who were caregivers to the elderly found that while the curriculum emphasised sex differences, the participants voiced ideas and negotiated identities that sidestepped gendered conventions. Their refusal to adopt the workplace communiqué in the curriculum was hidden from management, raising questions about informal resistance strategies among immigrant women in tightly controlled workplaces.
The reasonable woman standard: a meta-analytic review of gender differences in perceptions of sexual harassment.

PubMed

Blumenthal, J A

1998-02-01

Courts and legislatures have begun to develop the "reasonable woman standard" (RWS) as a criterion for deciding sexual harassment trials. This standard rests on assumptions of a "wide divergence" between the perceptions of men and women when viewing social-sexual behavior that may be considered harassing. Narrative reviews of the literature on such perceptions have suggested that these assumptions are only minimally supported. To test these assumptions quantitatively, a meta-analytic review was conducted that assessed the size, stability, and moderators of gender differences in perceptions of sexual harassment. The effect of the actor's status relative to the target also was evaluated meta-analytically, as one alternative to the importance of gender effects. Results supported the claims of narrative reviews for a relatively small gender effect, and draw attention to the status effect. In discussing legal implications of the present findings, earlier claims are echoed suggesting caution in establishing the reasonable woman standard, and one alternative to the RWS, the "reasonable victim standard," is discussed.

In developed countries, systolic blood pressure is known to increase with age. Metabolic risks may generally worse with increasing age. But this trend may be modified by environmental factors which are different between gender and generation. The aim of this study was to examine the relationship between age and gender-related difference in cardio-metabolic risks and life style factors in the Japanese general population. We studied 3628 inhabitants of Watari (mean age 63.9 yrs, 42.5% men), Miyagi prefecture, who participated in a health check-up in 2009. Anthropometry, sitting blood pressures, fasting blood samples were examined. Unhealthy dietary behaviors (night meal, late dinner, fast eating, skipping breakfast, smoking, heavy drinking, lack of regular exercise) were evaluated by standard questionnaire. Presence or absence of each behavior was scored 0 or 1 and total score was calculated as healthy life style score (range 0 to 7, higher the better). Gender difference in age-related changes in blood pressures, BMI, lipid and glucose metabolism were examined by two way ANOVA. Systolic blood pressure was continuously increased from age 30 s to 70 s in both genders. Systolic blood pressure was significantly higher in men than in women in age 30 s (122.0 ± 13.9 vs. 113.3 ± 12.8 mmHg, p < 0.001) but the difference decreased with an increase in age. Similar gender interaction was observed for diastolic blood pressure, BMI, triglyceride and high density lipoprotein (all p < 0.001) but was not for HbA1c. The healthy life style score was lowest in men age 30 s (5.1 ± 1.5) and it increased with an increase in age. Women demonstrated significantly higher healthy life style score than men in all generations. The gender difference in the score was largest in age 30 s and decreased with an increase in age. Cardio-metabolic risks are worse in men than in women in young generation but this gender difference diminishes with age. The gender difference in the young may be largely attributable to life style factors. Glucose metabolism may be less affected by life style than blood pressure or lipid.

The aim of our study was to evaluate the effects of gender on recovery of knee joint biomechanics over the stance phase of gait after reconstruction of the anterior cruciate ligament (ACL). Gait parameters and knee joint kinematics and kinetics were compared in 32 patients (16 male and 16 female) who underwent ACL reconstruction for a unilateral ACL deficiency, with comparison to an age-, height-, and weight-matched Control group. Knee flexion, adduction and tibial rotation angles were measured and knee extension and abduction moment was calculated by inverse dynamics methods. Females exhibited more tibial external rotation, in both the Control and ACL groups (P<0.05), which was not changed after ACL reconstruction. Prior to reconstruction, sagittal plane biomechanics were changed, in both males and females, compared to the Control groups (P<0.05). These abnormal sagittal plane mechanics were recovered at 12months, but not six months post-reconstruction. We identified gender-based differences in tibial rotation that influenced the kinematics and kinetics of the knee over the stance phase of gait, both pre-operatively and post-ACL reconstruction. Evaluation of biomechanical effects of ACL injury, before and after reconstruction, should be separately evaluated for females and males. Copyright © 2017 Elsevier B.V. All rights reserved.

To evaluate the motivational effect of the Project WebHealth study procedures and intervention components on weight-related health behavior changes in male and female college students. Process evaluation. Eight universities in the United States. Project WebHealth participants (n = 653; 29% men). Participants rated motivational effects of study procedures and intervention components. Participants were grouped into outcome-based health behavior categories based on achievement of desired targets for fruit and vegetable intake, physical activity, and/or body weight. Differences in motivation from each procedure and component were analyzed by gender- and outcome-based health behavior category. Women were generally more motivated than men. Compared to those who did not meet any target health behaviors, men with improved health outcomes (68%) were significantly more motivated by the skills to fuel the body lesson, goal setting, and research snippets. Their female counterparts (63%) were significantly more motivated by the lessons on body size and eating enjoyment, and by the suggested weekly activities. Specific study procedures and components of Project WebHealth motivated study participants to improve their weight-related health behaviors, and they differed by gender. Findings support the need for gender-tailored interventions in this population. Copyright © 2013 Society for Nutrition Education and Behavior. Published by Elsevier Inc. All rights reserved.

Cardiac remodeling is the pathological basis of various cardiovascular diseases. In this study, we found gender-related differences in β-adrenergic receptor (AR)-mediated pathological cardiac remodeling. Cardiac remodeling model was established by subcutaneous injection of isoprenaline (ISO) for 14 days. Heart rate (HR), mean arterial pressure (MAP), and echocardiography were obtained on 7th and 14th days during ISO administration. Myocardial cross-sectional area and the ratio of heart mass to tibia length (HM/TL) were detected to assess cardiac hypertrophy. Picro-Sirius red staining (picric acid + Sirius red F3B) was used to evaluate cardiac fibrosis. Myocardial capillary density was assessed by immunohistochemistry for von Willebrand factor. Further, real-time PCR was used to measure the expression of β1-AR and β2-AR. Results showed that ISO induced cardiac remodeling, the extent of which was different between female and male mice. The extent of increase in cardiac wall thickness, myocardial cross-sectional area, and collagen deposition in females was less than that in males. However, no gender-related difference was observed in HR, MAP, cardiac function, and myocardial capillary density. The distinctive decrease of β2-AR expression, rather than a decrease of β1-AR expression, seemed to result in gender-related differences in cardiac remodeling.

The role of gender on long-term infrainguinal open surgery outcomes still remains uncertain in critical limb ischemia patients. The aim of this study is to evaluate the gender-specific differences in patient characteristics and long-term clinical outcomes in terms of survival, primary patency and limb salvage among patients undergoing infrainguinal open surgery for CLI. All consecutive patients undergoing infrainguinal open surgery for critical limb ischemia between 2003 and 2012 were included. Survival, limb salvage and primary patency rates were assessed. Independent outcome determinants were identified by the Cox proportional hazard ratio using age and gender as adjustment factors. 584 patients (269 women and 315 men, mean age 76 and 71 years respectively) underwent 658 infrainguinal open surgery (313 in women and 345 in men). Survival rate at 6 years was lower among women compared to men with 53.5% vs 70.9% (p < 0.001). The same applied to primary patency (35.9% vs 52.4%, p < 0.001) and limb salvage (54.3% vs 81.1%, p < 0.001) at 6 years. Female-gender was an independent factor predicting death (hazard ratio 1.50), thrombosis (hazard ratio 2.37) and limb loss (hazard ratio 7.05) in age and gender-adjusted analysis. Gender-related disparity in critical limb ischemia open surgical revascularization outcomes still remains. Copyright © 2015 European Society for Vascular Surgery. Published by Elsevier Ltd.

2006-11-01

We administered the 18-item Recalled Childhood Gender Questionnaire-Revised (RCGQ-R), female version, to 147 adult women with congenital adrenal hyperplasia (CAH) representing three different degrees of prenatal androgenization due to 21-hydroxylase deficiency and to non-CAH controls. A principal components analysis generated three components accounting for 46%, 9%, and 6% of the variance, respectively. Corresponding unit-weighted scales (high scores = feminine) were labeled Gender Role (13 items; Cronbach alpha = .91), Physical Activity (3 items; alpha = .64), and Cross-Gender Desire (2 items; alpha = .47). Discriminant validity was demonstrated in terms of highly significant comparisons across the four groups. We conclude that the first 2 RCGQ-R scales show good psychometric qualities, but that the third scale needs to be further evaluated in a sample that includes women with gender identity disorder.

Many astronomical concepts cannot be understood without a developed understanding of four spatial-mathematics domains defined as follows: a) Geometric Spatial Visualization (GSV) - Visualizing the geometric features of a system as it appears above, below, and within the system’s plane; b) Spatial Projection (SP) - Projecting to a different location and visualizing from that global perspective; c) Cardinal Directions (CD) - Distinguishing directions (N, S, E, W) in order to document an object’s vector position in space; and d) Periodic Patterns - (PP) Recognizing occurrences at regular intervals of time and/or space. For this study, differences were examined between groups of sixth grade students’ spatial-scientific development pre/post implementation of an Earth/Space unit. Treatment teachers employed a NASA-based curriculum (Realistic Explorations in Astronomical Learning), while control teachers implemented their regular Earth/Space units. A 2-level hierarchical linear model was used to evaluate student performance on the Lunar Phases Concept Inventory (LPCI) and four spatial-mathematics domains, while controlling for two variables (gender and ethnicity) at the student level and one variable (teaching experience) at the teacher level. Overall LPCI results show pre-test scores predicted post-test scores, boys performed better than girls, and Whites performed better than non-Whites. We also compared experimental and control groups’ by spatial-mathematics domain outcomes. For GSV, it was found that boys, in general, tended to have higher GSV post-scores. For domains CD and SP, no statistically significant differences were observed. PP results show Whites performed better than non-Whites. Also for PP, a significant cross-level interaction term (gender-treatment) was observed, which means differences in control and experimental groups are dependent on students’ gender. These findings can be interpreted as: (a) the experimental girls scored higher than the control girls and/or (b) the control group displayed a gender gap in favor of boys while no gender gap was displayed within the experimental group.

While decreasing trend in gender differences in alcohol use disorders was reported in Western countries, the change in Asian countries is unknown. This study aims to explore the shifts in gender difference in alcohol abuse (AA) and dependence (AD) in Korea. We compared the data from two nation-wide community surveys to evaluate gender differences in lifetime AA and AD by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Face-to-face interviews using the Composite International Diagnostic Interview (CIDI) were applied to all subjects in 2001 (n=6,220) and 2011 (n=6,022). Male-to-female ratio of odds was decreased from 6.41 (95% CI, 4.81-8.54) to 4.37 (95% CI, 3.35-5.71) for AA and from 3.75 (95% CI, 2.96-4.75) to 2.40 (95% CI, 1.80-3.19) for AD. Among those aged 18-29, gender gap even became statistically insignificant for AA (OR, 1.59; 95% CI, 0.97-2.63) and AD (OR, 1.18; 95% CI, 0.80-2.41) in 2011. Men generally showed decreased odds for AD (0.55; 95% CI, 0.45-0.67) and women aged 30-39 showed increased odds for AA (2.13; 95% CI 1.18-3.84) in 2011 compared to 2001. Decreased AD in men and increased AA in women seem to contribute to the decrease of gender gap. Increased risk for AA in young women suggests needs for interventions. PMID:26539014

Background Tobacco workers are exposed to several respiratory occupational sensitizers. Methods A representative cross-sectional study was carried out on 2469 tobacco family farming growers. Gender-stratified multivariate analyses evaluated the association between wheezing and socio-demographic, behavioral and occupational variables. Results Wheezing prevalence was 11.0% with no difference between genders. Among men, age, smoking, strenuous work, pesticide use, contact with vegetable dust and dried tobacco dust, lifting sticks with tobacco leaves to the curing barns and green tobacco sickness (GTS) were risk factors for wheezing. Among women, family history of asthma, tying hands of tobacco, strenuous work, contact with chemical disinfectants and GTS were positively associated with wheezing. Harvesting lower tobacco leaves was a protective factor for the outcome in both genders. Conclusions Pesticides, dusts exposure and GTS were risk factors for wheezing. The synergic effect of these factors needs to be better evaluated to improve prevention. PMID:26471879

From a global perspective, the universality of gender-related societal issues is particularly significant. Although gender inequality is considered a sociological problem, the large number of female victims in disasters warrants an assessment of disaster management sciences. In this article, related concepts are discussed based on their relevance sociologically and in disaster management to develop a common terminology and examine this complex topic, which is rooted in different social profiles and anthropological heterogeneity throughout the world. A brief history is discussed, and significant examples are provided from different disasters in Turkey to illustrate why a woman-oriented approach should be adopted when evaluating concepts of gender inequality. Observations of disasters have shown that it is important to apply international standards (humanitarian charter and minimum disaster response standards), especially during periods of response and rehabilitation. Relevant factors related to gender should be included in these standards, such as women’s health and hygiene, which will be discussed in more detail. A woman-based approach is designed in relation to two aspects: risks and resources. Thus, gender-sensitive methods of mitigating and preventing disasters are provided. The main purpose of the article is to contribute to the development of a universal culture that prioritizes gender in disaster management. PMID:26016435
Self-esteem and life satisfaction in adolescents-gender and age as potential moderators.

The present paper investigated gender differences on life satisfaction and self-esteem as well as the association between self-esteem and life satisfaction in Norwegian adolescents aged 13-18 years. The potential moderating role of gender and age in the relation between self-esteem and life satisfaction was also investigated. A total of 1,239 adolescents from public elementary and secondary schools in mid-Norway participated in the school-based survey study. Mean score differences on the variables used in the study were tested using t tests. Hierarchical multiple regression analysis was used to evaluate the association between self-esteem and life satisfaction, controlled for gender, age, stress, subjective health, and chronic health conditions. The results showed that boys scored higher than girls on both self-esteem and life satisfaction. Self-esteem was positively associated with life satisfaction, explaining 24 % of the variance. However, no interaction effect of gender × self-esteem or age × self-esteem was found in relation to life satisfaction. The results give support for that boys report higher self-esteem and life satisfaction than girls. Self-esteem has a positive role in association with adolescents' life satisfaction, and this relationship is equally strong for both genders and across age.

Objective To determine if performance differences exist between male and female students on a 6-week obstetrics and gynecology (Ob/Gyn) clerkship and to evaluate potential variables that might underlie any observed variations. Study Design Final clerkship grades and component scores (clinical evaluations, objective structured clinical examination [OSCE], oral examination, and National Board of Medical Examiners [NBME] subject examination) from July 2007 to June 2010 were matched by student and analyzed by gender. Basic science grade point average (GPA) and initial United States Medical Licensing Exam (USMLE) Step 1 scores were used to establish students’ baseline medical knowledge. On a post-clerkship questionnaire, a subset of students reported the numbers of procedures they performed during the clerkship; students also completed online pre- and post-clerkship questionnaires reflecting their self-assessed confidence in women's health clinical skills. Results Scores were analyzed for 136 women and 220 men. Final clerkship grades were significantly higher for females than for males (89.05 vs. 87.34, p=0.0004, η 2=0.08). Specifically, females outscored males on the OSCE, oral, and NBME subject examination portions of the clerkship but not clinical evaluations. Males reported completing fewer breast examinations (p=0.001, η 2=0.14). Pre-clerkship, males were significantly less confident than females in women's health clinical skills (p<0.01) but reached similar levels upon completion of the clerkship. No gender differences were detected for basic science GPA and USMLE Step 1 scores. Conclusion Student gender is associated with final grades on an Ob/Gyn clerkship. Further research regarding these differences should be explored. PMID:24300748
Gender differences in substance use disorders.

PubMed

Brady, K T; Randall, C L

Despite the fact that the rate of substance abuse and dependence is higher among men than it is among women, the prevalence rates, especially the more recent ones, indicate that a diagnosis of substance abuse is not gender specific. From the emerging literature on gender differences over the past 25 years, male and female substance abusers are clearly not the same. Women typically begin using substances later than do men, are strongly influenced by spouses or boyfriends to use, report different reasons for maintaining the use of the substances, and enter treatment earlier in the course of their illnesses than do men. Importantly, women also have a significantly higher prevalence of comorbid psychiatric disorders, such as depression and anxiety, than do men, and these disorders typically predate the onset of substance-abuse problems. For women, substances such as alcohol may be used to self-medicate mood disturbances, whereas for men, this may not be true. Although these comorbid disorders might complicate treatment for women, women are, in fact, responsive to treatment and do as well as men in follow-up. Gender differences and similarities have significant treatment implications. This is especially true for the telescoping phenomenon, in which the window for intervention between progressive landmarks is shorter for women than for men. This is also true for the gender differences in physical and sexual abuse, as well as other psychiatric comorbidity that is evident in female substance abusers seeking treatment. The barriers to treatment for women are being addressed in many treatment settings to encourage more women to enter treatment, and family and couples therapy are standard therapeutic interventions. Negative consequences associated with substance abuse are different for men and women, and gender-sensitive rating instruments must be used to measure not only the severity of the problem but also to evaluate treatment efficacy. To determine whether gender differences observed over the past 25 years become less demarcated in comparisons of younger cohorts of substance abusers in the future will be interesting. Changing societal roles and attitudes toward women, the increase in women entering the workplace, in general, and into previously male-dominated sports and professions, in particular, may influence not only opportunities to drink but also drinking culture. Some gender differences likely will remain, but other gender differences will probably also emerge. The comparison of male and female substance abusers promises to be a fruitful one for researchers. The translation if the research findings to the treatment community to improve treatment outcome for both sexes will be an equally exciting challenge for the field.

The purpose of the study was (1) to investigate gender role behaviors of boys with hypospadias compared with groups of unaffected boys and girls using parental reports and direct observations; and (2) to directly observe effects of socialization (mothers' presence) on children's gender role behaviors. Ages of 19 children with hypospadias ranged from 3 to 7 years, and each of them were matched to controls of unaffected boys and girls by age. All the children participated with their mothers. Children's gender role behaviors and their mothers' behaviors were evaluated using an observation coding system. Mothers also completed questionnaires regarding their children's gender role behaviors. Results indicated no atypical gender role behavior for the boys with hypospadias and no direct effects of socialization on their gender role behaviors. However, differences were found in negative communicative behaviors between boys with hypospadias and unaffected boys, suggesting a possible role of socialization. © The Author 2014.

Sex Differences in Emotional Evaluation of Film Clips: Interaction with Five High Arousal Emotional Categories.

Maffei, Antonio; Vencato, Valentina; Angrilli, Alessandro

2015-01-01

The present study aimed to investigate gender differences in the emotional evaluation of 18 film clips divided into six categories: Erotic, Scenery, Neutral, Sadness, Compassion, and Fear. 41 female and 40 male students rated all clips for valence-pleasantness, arousal, level of elicited distress, anxiety, jittery feelings, excitation, and embarrassment. Analysis of positive films revealed higher levels of arousal, pleasantness, and excitation to the Scenery clips in both genders, but lower pleasantness and greater embarrassment in women compared to men to Erotic clips. Concerning unpleasant stimuli, unlike men, women reported more unpleasantness to the Compassion, Sadness, and Fear compared to the Neutral clips and rated them also as more arousing than did men. They further differentiated the films by perceiving greater arousal to Fear than to Compassion clips. Women rated the Sadness and Fear clips with greater Distress and Jittery feelings than men did. Correlation analysis between arousal and the other emotional scales revealed that, although men looked less aroused than women to all unpleasant clips, they also showed a larger variance in their emotional responses as indicated by the high number of correlations and their relatively greater extent, an outcome pointing to a masked larger sensitivity of part of male sample to emotional clips. We propose a new perspective in which gender difference in emotional responses can be better evidenced by means of film clips selected and clustered in more homogeneous categories, controlled for arousal levels, as well as evaluated through a number of emotion focused adjectives.

To assess mid-trimester amniotic fluid concentrations of interleukin (IL)-6, IL-8, tumor necrosis factor (TNF)-α, and lipopolysaccharide binding protein (LBP) in pregnancies with normal outcome and correlate them with gestational week (GW), parity, and fetal gender. Cytokine concentrations were measured within a week of amniocentesis during GW 15+0 to 20+6 and correlated with GW at birth, parity, and fetal gender. After exclusion of women with an adverse pregnancy outcome or those lost to follow-up, 273 consecutive patients were evaluated (median parity: 1; range: 0-5). Ranges for IL-6, IL-8, TNF-α, and LBP were 4.9-2620 pg/mL, 36.2-5843 pg/mL, 8.0-28.2 pg/mL, and 0.06-1.9 μg/mL, respectively. IL-6, IL-8, and LBP values did not respectively differ among time points, but TNF-α values did between the 15(th) and 16(th) and the 15(th) and 18(th) weeks of gestation (P<0.05). No significant correlations between cytokine levels and parity or fetal gender were identified. Cytokine concentrations in amniotic fluid during the mid-trimester did not differ with parity or fetal gender. IL-6, IL-8, and LBP levels appeared stable with GW, whereas GW significantly influenced TNF-α concentrations. Further analyses are warranted to establish the role of cytokines in predicting adverse pregnancy outcomes.

To date, no studies have evaluated for differences in subjective and objective measures of sleep disturbance in oncology outpatients with and without pain. This descriptive study recruited 182 patients from two radiation therapy (RT) departments at the time of the patient’s simulation visit. Approximately 38% of the sample reported moderate to severe pain (i.e., worst pain intensity of 6.2 ± 2.4). After controlling for age, patients with pain reported worse sleep quality and more sleep disturbance using the Pittsburgh Sleep Quality Index. With the General Sleep Disturbance Scale, patients with pain reported poorer sleep quality, increased use of sleep medications, and more daytime sleepiness. In addition using an objective measure of sleep disturbance (i.e., actigraphy), significant Gender × Pain interactions were found for sleep onset latency, percentage of time awake at night, wake duration, total sleep time, and sleep efficiency. While no differences were found in female patients, males with pain had worse scores than males without pain. Findings from this study suggest that pain and sleep disturbance are prevalent in oncology outpatients and that a patient’s age and gender need to be considered in any evaluation of the relationship between pain and sleep. Perspective: The effects of pain on subjective and objective sleep parameters appear to be influenced by both patients’ age and gender. PMID:21146465

This study aimed to evaluate gender differences in the deficit of insight in psychosis and determine influences of clinical, functional, and sociodemographic variables. A multicenter sample of 401 adult patients with schizophrenia and other psychotic disorders who agreed to participate was evaluated in four centers of the metropolitan area of Barcelona (Catalonia). Psychopathological assessment was performed using the Positive and Negative Syndrome Scale Lindenmayers' Factors. Insight and its dimensions were assessed by means of the Scale of Unawareness of Mental Disorder. Significant differences were apparent neither between men and women in the three dimensions of insight, nor in the total awareness, nor in the total attribution subscales. However, statistically significant differences were found in awareness and attribution of particular symptoms. Women showed a worse awareness of thought disorder and alogia and a higher misattribution of apathy. Higher cognitive and positive symptoms, early stage of the illness, and having been married explained deficits of insight dimensions in women. In men, other variables such as lower functioning, higher age, other psychosis diagnosis, and, to a lower extent, higher scores in cognitive, positive, and excitative symptoms, explained deficits of insight dimensions. These data could help to design gender-specific preventive and therapeutic strategies. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The purpose of this study was to evaluate, for both genders and two elderly age groups, differences in lightness, chroma, and hue of pairs of natural anterior teeth, so that more accurate information on color would be available for the production of dentures with a natural appearance. The subjects in the younger group (YG) were 54 to 56 years of age, those in the older group 73 to 75 (N = 195, 48% women). Tooth color was measured using a spectrophotometer. Mixed models were calculated for each pair of teeth, with gender as a fixed factor. Gender did not have a significant effect in either age group. In both groups, differences in chroma between upper canines and lateral incisors and in lightness and hue between upper and lower canines were observed. In the YG, additional differences were found, with the only exception of the comparison between upper central and lateral incisors. The nongender-specific color differences observed should be considered when producing denture teeth for these groups of patients, in order to come as close as possible to the natural color ideal.

Astaxanthin (Ax) is a ketocarotenoid of the xanthophyll family with activities such as antioxidation, preservation of the integrity of cell membranes and protection of the redox state and functional integrity of mitochondria. The aim of this study was to investigate potential gender-related differences in the effect of Ax on the aging rat brain. In females, interleukin 1 beta (IL1β) was significantly lower in treated rats in both cerebral areas, and in the cerebellum, treated animals also had significantly higher IL10. In males, no differences were found in the cerebellum, but in the hippocampus, IL1β and IL10 were significantly higher in treated rats. These are the first results to show gender-related differences in the effect of Ax on the aging brain, emphasizing the necessity to carefully analyze female and male peculiarities when the anti-aging potentialities of this ketocarotenoid are evaluated. The observations lead to the hypothesis that Ax exerts different anti-inflammatory effects in female and male brains. © 2015 Society of Chemical Industry.
Computer Programming Games and Gender Oriented Cultural Forms

NASA Astrophysics Data System (ADS)

AlSulaiman, Sarah Abdulmalik

I present the design and evaluation of two games designed to help elementary and middle school students learn computer programming concepts. The first game was designed to be "gender neutral", aligning with might be described as a consensus opinion on best practices for computational learning environments. The second game, based on the cultural form of dress up dolls was deliberately designed to appeal to females. I recruited 70 participants in an international two-phase study to investigate the relationship between games, gender, attitudes towards computer programming, and learning. My findings suggest that while the two games were equally effective in terms of learning outcomes, I saw differences in motivation between players of the two games. Specifically, participants who reported a preference for female- oriented games were more motivated to learn about computer programming when they played a game that they perceived as designed for females. In addition, I describe how the two games seemed to encourage different types of social activity between players in a classroom setting. Based on these results, I reflect on the strategy of exclusively designing games and activities as "gender neutral", and suggest that employing cultural forms, including gendered ones, may help create a more productive experience for learners.
A gender analysis of secondary school physics textbooks and laboratory manuals

NASA Astrophysics Data System (ADS)

Kostas, Nancy Ann

Secondary school physics textbooks and laboratory manuals were evaluated for gender balance. The textbooks and manuals evaluated were all current editions available at the time of the study with copyrights of 1988 to 1992. Illustrations, drawings and photographs were judged gender balanced based on the number of men and women, boys and girls shown in both active and passive roles. Illustrations, drawings and photographs were also evaluated by the number of male and female scientists identified by name. The curricular content of the textbooks was analyzed for gender balance by three criteria: the number of named male and female scientists whose accomplishments were described in the text; the number of careers assigned to men and women; and the number of verbal analogies assigned to girls interests, boys interests or neutral interests. The laboratory activities in the manuals were categorized as demonstrations, experiments and observations. Three of each of these types of activities from each manual were analyzed for skills and motivating factors important to girls as identified by Potter and Rosser (1992). Data were analyzed by use of descriptive statistics of frequencies, means and chi-square goodness of fit. The.05 level of significance was applied to all analyses based upon an expected frequency of 50 - 50 percentage of men and women and a 4.5 percent for women scientists to 95.5 percent for men scientists. The findings were as follows. None of the textbooks had a balance of men/women, boys/girls in the illustrations, drawings and photographs. The Hewitt (Scott-Foresman, 1989) textbook was the only textbook with no significant difference. Using the expected frequency for male and female scientists, two textbooks were gender balanced for illustrations, drawings and photographs while all textbooks were gender balanced for described accomplishments of scientists. The Hewitt (Scott Foresman, 1989) textbook had the only gender balanced representation of careers. Verbal analogies were gender fair in all textbooks where the second half of the content dealing with light, electricity and magnetism was analyzed. Only the Hewitt (Addison-Wesley, 1992) was gender balanced for the first half text verbal analogies. All laboratory manuals had skills and motivating factors important to girls.

Studies from high-income countries have shown that women receive less aggressive diagnostics and treatment than men in acute coronary syndromes (ACS), though their short-term mortality does not appear to differ from men. Data on gender differences in ACS presentation, management, and outcomes are sparse in India. The Detection and Management of Coronary Heart Disease (DEMAT) Registry collected data from 1,565 suspected ACS patients (334 women; 1,231 men) from ten tertiary care centers throughout India between 2007-2008. We evaluated gender differences in presentation, in-hospital and discharge management, and 30-day death and major adverse cardiovascular event (MACE; death, re-hospitalization, and cardiac arrest) rates. Women were less likely to present with STEMI than men (38% vs. 55%, p<0.001). Overall inpatient diagnostics and treatment patterns were similar between men and women after adjustment for potential confounders. Optimal discharge management with aspirin, clopidogrel, beta-blockers, and statin therapy was lower for women than men, (58% vs. 65%, p = 0.03), but these differences were attenuated after adjustment (OR = 0.86 (0.62, 1.19)). Neither the outcome of 30-day mortality (OR = 1.40 (0.62, 3.16)) nor MACE (OR = 1.00 (0.67, 1.48)) differed significantly between men and women after adjustment. ACS in-hospital management, discharge management, and 30-day outcomes did not significantly differ between genders in the DEMAT registry, though consistently higher treatment rates and lower event rates in men compared to women were seen. These findings underscore the importance of further investigation of gender differences in cardiovascular care in India.

Gender-related differences are frequently used in medicine. Electrocardiograms are also subject to such differences. This study evaluated gender differences in ECG parameters of young athletes, discussing the possible implications of these differences for ECG criteria used in the cardiovascular screening of young athletes. Observational cross-sectional study. In 2013 and 2014 all the ECGs from the cardiovascular screenings performed at University Sports Medical Centre in Groningen of the student athletes who wanted to participate in a college sports program were collected. The ECG characteristics were scored using computer-based measurements and the Seattle ECG criteria. The study population included 1436 athletes, of which 72% were male. Male athletes were older (19.3 years vs. 18.6 years), participated in sports more frequently (4.0/week vs. 3.8/week) and spent more hours per week practising sports (6.4h/week vs. 5.8h/week) than female athletes. Male athletes had significantly higher PR intervals (149ms vs. 141ms), lead voltages and QRS duration (98ms vs. 88ms). Female athletes had significantly higher resting heart rates (69/min vs. 64/min) and QTc intervals (407ms vs. 400ms). Male athletes also had significantly higher amounts of sinus bradycardia (38.3% vs. 23.0%), incomplete RBBB (15.0% vs. 3.7%), early repolarisation (4.5% vs. 1.0%) and isolated QRS voltage criteria for LVH (26.3% vs. 4.6%). All P-values were ≤0.001. ECGs of young athletes demonstrate gender-related differences. These differences could be considered in their cardiovascular screening. For the Seattle ECG criteria we advise additional research into the clinical implications of using gender-based cut-off values for the QRS duration in the intraventricular conduction delay criterion.

After age 65, the incidence of episodic memory decline in males is greater than in females. We explored the influence of anxiety and depression on objective and subjective memory performance in a diverse sample of community-residing older adults. The study was a secondary analysis of data on three samples of adults from two states, Ohio and Texas: a community sample (n = 177); a retirement community sample (n = 97); and the SeniorWISE Study (n = 265). The sample of 529 adults was 74% female, the average age was 76.58 years (range = 59-100 years), and educational attainment was 13.12 years (±3.68); 68% were Caucasian, and 17% had depressive symptoms. We found no memory performance differences by gender. Males and females were similarly classified into the four memory performance groups, with almost half of each gender in the poor memory category. Even though males had greater years of education, they used fewer compensatory memory strategies. The observed gender differences in memory were subjective evaluations, specifically metamemory. Age was not a significant predictor of cognition or memory performance, nor did males have greater memory impairment than females.

Suicide among adolescents is an emerging global public health problem as well as a socioeconomic problem. Stress-coping strategies have been shown to be associated with suicidal ideation. We examined coping behaviors related to suicidal ideation and gender differences in adolescents using the data from the 2010 Korea Youth Risk Behavior Survey (ages 12-19 years; N = 73,238). Logistic regression analysis was used to evaluate associations between suicidal ideation and specific coping behaviors while controlling for potentially confounding variables. In both male and female groups, the coping behavior "drinking alcoholic beverages" and "smoking cigarettes" were positively associated with suicidal ideation. "Watching TV," "playing online/mobile games," and "sleeping" were negatively associated with suicidal ideation in both groups. In males, "engaging in sports" was negatively related to suicidal ideation. In females, "venting by talking to others" and "eating" were negatively related to suicidal ideation. The results indicate that there are gender differences in the effects of coping behaviors on adolescent suicidal ideation, and that developing adaptive coping strategies may function to reduce suicidality. Future studies are needed to examine whether improving coping skills can reduce suicidal ideation in a gender-specific manner.

To examine the relationship between shame and the behavioral and attitudinal features of eating disorders in men and women diagnosed with binge-eating disorder (BED). Participants were 188 consecutively evaluated adults (38 men and 150 women) who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition, criteria for BED. Participants were interviewed and completed a battery of measures assessing shame, behavioral and attitudinal features of eating disorders, and general psychological functioning. Shame did not differ significantly by gender and was not associated with BMI or binge-eating frequency. Shame was significantly associated with the attitudinal features of eating disorders, even after controlling for levels of depression and self-esteem. When considered separately by gender and controlling for depression and self-esteem, shame was associated with body dissatisfaction in men and with weight concern in women. Men and women with BED, who presented for treatment, reported similar levels of shame. Overall, while shame was related to attitudinal features, the specific associations differed by gender. For men, shame was related to how dissatisfied they felt with their bodies, whereas for women, shame was associated with concerns about weight. Interestingly, shame was not related to BMI or binge-eating frequency in men or women. These results provide preliminary support for self-conscious emotions playing different roles in men and women with BED.

To investigate risk sexual for HIV infection among young adult night school students (18 to 25 years old) and to assess gender differences in sexual practices and the impact of AIDS prevention program. A longitudinal intervention study was carried out among students of four public inner-city night schools, in the city of São Paulo, Brazil, randomized into two groups: an intervention group and a control one. Three hundred and ninety-four students participated in the study; 77% completed the post-intervention questionnaire. The intervention consisted of a "Safer Sex Workshop" where the following topics were discussed: Aids symbolism, risk perception, influences of gender norms on attitudes, Aids-related knowledge, erotic and reproductive body, sexual pleasure, and condom use negotiation. Statistical analysis was performed using Pearson's Chi-square test and variance. The frequency of condom use was low (33%). There were significant gender differences concerning sexuality and AIDS prevention. Workshop evaluation showed a statistically significant impact on women, who improved chiefly their attitudes regarding safer sex. Changes were not significant among men. HIV risk infection can be lowered but more significant results can be achieved if gender differences and sexual scripts are taken into account while developing specific long-term community programs.

Chronic obstructive pulmonary disease (COPD) is generally considered to be prevalent in males. However, smoking is rising in women in developing and developed countries, while exposure to biomass fuel for domestic purposes is a recognized risk factor among females. Females developing more severe COPD patterns due to tobacco exposure than men maybe due to a genetic predisposition, a greater dose-dependent effect of smoke related to smaller airways caliber and an increased oxidative stress with augmented TGF-beta1 signaling. Gender hormones also seem to be involved in tobacco-smoke metabolism and in lung and pulmonary development. while menopause is associated with accelerated alveolar loss and decline of lung function pulmonary function. The time to diagnosis differs between the sexes since a lower rate of spirometry is performed in women. Also comorbidities differ between genders: osteoporosis, inflammatory bowel diseases, reflux, hypertension, rheumatoid arthritis, and mental diseases are more common in women. Women pay more attention to breathlessness, maybe due to higher emotional response and anxiety. These elements could lead to higher hospitalization rates in women. The aim of this review is to provide the available evidence with the aim of inviting healthcare professionals to evaluate gender differences in patients with COPD, key point for optimizing the care plan.

Operation Iraqi Freedom offered an opportunity to study the role of alcohol use among men and women serving in the US Army. The goal of this study was to determine whether there are gender-based differences in alcohol use among US Army soldiers, and if so, to evaluate the role of alcohol education efforts in the military. In February 2005, 1200 individuals enlisted in the US Army were asked to complete a 29-item questionnaire regarding alcohol-use patterns. Survey topics included attitudes toward alcohol consumption and associated negative consequences. Six hundred eighty-five men and 325 women (N=1010) responded to the questionnaire for an overall response rate of 84%. Although men were more likely to engage in "bolus" drinking (ie, binge drinking), women exceeded established guidelines for safe alcohol consumption at a risk-adjusted rate nearly twice that of men. In addition, for individuals whose behaviors were not in conformity with public health guidelines for safe alcohol consumption, the severity of reported negative consequences was influenced by gender. Women initially experience greater psychosocial impairment, and-should harmful drinking patterns progress to alcohol dependency-they are at greater risk of injury, morbidity, and mortality than men. Several gender-specific differences in alcohol-consumption patterns were found. Because the present study also found that women generally have more interest in educational interventions for alcohol abuse issues, however, researchers conclude that the efficacy of US Army risk-reduction programs would be improved by addressing gender-based differences.

Social support has been shown to be an important factor in improving depression symptom outcomes, yet less is known regarding its impact on antidepressant medication adherence. This study sought to evaluate the role of perceived social support on adherence to new antidepressant medication prescriptions in later-life depression. Data from two prospective observational studies of participants ≥60 years old, diagnosed with depression, and recently prescribed a new antidepressant (N = 452). Perceived social support was measured using a subscale of the Duke Social Support Index and medication adherence was assessed using a validated self-report measure. At four-month follow up, 68% of patients reported that they were adherent to antidepressant medication. Examining the overall sample, logistic regression analysis demonstrated no significant relationship between perceived social support and medication adherence. However, when stratifying the sample by social support, race, and gender, adherence significantly differed by race and gender in those with inadequate social support: Among those with low social support, African-American females were significantly less likely to adhere to depression treatment than white females (OR = 4.82, 95% CI = 1.14-20.28, p = 0.032) and white males (OR = 3.50, 95% CI = 1.03-11.92, p = 0.045). There is a significant difference in antidepressant medication adherence by race and gender in those with inadequate social support. Tailored treatment interventions for low social support should be sensitive to racial and gender differences.
Gender equity: A study of classroom interactions of sixth-grade science teachers before and after gender equity training

NASA Astrophysics Data System (ADS)

Giuliano, Joanne

The researcher investigated teachers' perceptions of their interactions with students in their 6th grade science classrooms and the effects of gender equity training on teachers' interactions with students. Teacher perceptions were measured at pretest and posttest using the Gender Equity Teacher-Student Interaction Questionnaire (GETSIQ). The outcomes from one day of gender equity training, using the Gender Equity Video and Instructional Guide, were measured at pretest, posttest, and follow-up using the INTERSECT scale. A non-random sample of twenty 6th grade science teachers from five middle schools participated in the study. Ten teachers were assigned to each of the control or experimental groups. The first hypothesis posited that teacher perceptions of and actions toward male and female students in sixth grade science classrooms would be different as reflected by scores on the GETSIQ. The hypothesis was partially supported. Teachers reported significantly different amounts of acknowledgment, attention in general, and attention to questions, responses, and comments for boys and girls, and different evaluations based on their expectations for a student. Following training, teachers from the experimental group obtained somewhat higher scores, though the differences were not statistically significant. Hypothesis 2 stated that gender equity training would increase equitable teacher interactions with male and female students as demonstrated by scores on the INTERSECT Checklist. This hypothesis was partially supported. A comparison of the Intersect checklist (praise, acceptance, remediation, criticism) revealed that teachers were observed to more equally give praise to boys and girls following training, male teachers engaged in more acceptance responses with girls, and female teachers had more equitable distribution of acceptance. Male teachers increased the amount of remediation to girls, and female teachers continued to provide more remediation to boys. The differences between pretest and posttest were statistically significant. There was some reversion to pretest levels interactions at follow-up. The results of the study support the effectiveness of gender equity training in facilitating increased awareness and behavioral change in teachers. However, training needs to be of longer duration for continued effectiveness.

The aim was to describe the effect of age, gender, height, different stages of human life, and body fat on the functional muscle-bone unit. All these factors had a significant effect on the functional muscle-bone unit and should be addressed when assessing functional muscle-bone unit in children and adults. For the clinical evaluation of the functional muscle-bone unit, it was proposed to evaluate the adaptation of the bone to the acting forces. A frequently used parameter for this is the total body less head bone mineral content (TBLH-BMC) determined by dual-energy X-ray absorptiometry (DXA) in relation to the lean body mass (LBM by DXA). LBM correlates highly with muscle mass. Therefore, LBM is a surrogate parameter for the muscular forces acting in everyday life. The aim of the study was to describe the effect of age and gender on the TBLH-BMC for LBM and to evaluate the impact of other factors, such as height, different stages of human life, and of body fat. As part of the National Health and Nutrition Examination Survey (NHANES) study, between the years 1999-2006 whole-body DXA scans on randomly selected Americans from 8 years of age were carried out. From all eligible DXA scans (1999-2004), three major US ethnic groups were evaluated (non-Hispanic Whites, non-Hispanic Blacks, and Mexican Americans) for further statistical analysis. For the statistical analysis, the DXA scans of 8190 non-Hispanic White children and adults (3903 female), of 4931 non-Hispanic Black children and adults (2250 female) and 5421 of Mexican-American children and adults (2424 female) were eligible. Age, gender, body height, and especially body fat had a significant effect on the functional muscle-bone unit. When assessing TBLH-BMC for LBM in children and adults, the effects of age, gender, body fat, and body height should be addressed. These effects were analyzed for the first time in such a large cohort.

To the extent that sex differences are mediated by mechanisms such as sex-roles and beliefs, individual differences in these more proximate traits should account for significant portions of relevant sex differences. Differences between women and men in reactions to sexual and emotional infidelity were assessed in a large sample of participants (n = 477), and these target reactions were evaluated as a function of many potential proximate mediators (infidelity implications beliefs, gender-role beliefs, interpersonal trust, attachment style, sociosexuality, and culture of honor beliefs) and as a function of participant sex. Results found a consistent sex difference that was not mediated by any other variables, although a handful of other variables were related to male, but not female, individual differences. These findings suggest particularly promising directions for future research on integrating evolutionarily based sex differences and proximate individual differences.

This study aimed to understand parents' evaluations of the way they integrated work-family demands to manage food and eating. Employed, low/moderate-income, urban, U.S., Black, White, and Latino mothers (35) and fathers (34) participated in qualitative interviews exploring work and family conditions and spillover, food roles, and food-choice coping and family-adaptive strategies. Parents expressed a range of evaluations from overall satisfaction to overall dissatisfaction as well as dissatisfaction limited to work, family life, or daily schedule. Evaluation criteria differed by gender. Mothers evaluated satisfaction on their ability to balance work and family demands through flexible home and work conditions, while striving to provide healthy meals for their families. Fathers evaluated satisfaction on their ability to achieve schedule stability and participate in family meals, while meeting expectations to contribute to food preparation. Household, and especially work structural conditions, often served as sizeable barriers to parents fulfilling valued family food roles. These relationships highlight the critical need to consider the intersecting influences of gender and social structure as influences on adults' food choices and dietary intake and to address the challenges of work and family integration among low income employed parents as a way to promote family nutrition in a vulnerable population.

How Oxytocin Receptor (OXTR) Single Nucleotide Polymorphisms Act on Prosociality: The Mediation Role of Moral Evaluation.

PubMed

Prosociality is related to numerous positive outcomes, and mechanisms underlying individual differences in prosociality have been widely discussed. Recently, research has found converging evidence on the influence of the oxytocin receptor ( OXTR ) gene on prosociality. Meanwhile, moral reasoning, a key precursor for social behavior, has also been associated with variability in OXTR gene, thus the relationship between OXTR and prosociality is assumed to be mediated by moral evaluation. The current study examines the relationship in question, and includes gender as a potential moderator. Self-reported prosociality on Prosocial Tendencies Measure and evaluation on the moral acceptability of behaviors in stories from 790 Chinese adolescents (32.4% boys) were analyzed for the influence of their OXTR single nucleotide polymorphisms (SNPs). Results showed that SNP at site rs2254298 was indirectly associated with prosocial behaviors via moral evaluation of behaviors, and this effect was moderated by gender. Our findings suggest an indirect association between genetic variations in OXTR and prosociality through moral evaluation, indicating the potential pathway from genetic variability to prosociality through level of moral development. We also provide some evidence that the role of oxytocin system may to some extent depend on gender. These findings may promote our understanding of the genetic and biological roots of prosociality and morality.

Delayed gastric emptying is one of the reasons why functional dyspepsia (FD) occurs. The 13C-acetate breath test is widely used to evaluate gastric emptying. Nevertheless, the standard value of 13C-acetate breath test has not taken into account the gender difference of gastric emptying among healthy individuals. The main aim of this study was to readjust the standard value of 13C-acetate breath test in the light of gender differences. In addition, we clarified the prevalence and clinical characteristics of delayed gastric emptying in patients with FD using the modified standard values of 13C-acetate breath test. Fifty-two healthy individuals and 126 patients with patients with FD were enrolled. Gastric emptying was evaluated by the 13C-acetate breath test. The cut-off points of Tmax for the diagnosis of delayed gastric emptying were determined on the basis of results from healthy individuals making a distinction of genders. Gastroesophageal reflux symptoms, dyspeptic symptoms, scores of anxiety and depression, age, body mass index (BMI), smoking and alcohol consumption were compared between the delayed gastric emptying group and the non-delayed gastric emptying group. Since gastric emptying was delayed in healthy women compared with that in healthy men (Tmax, 53.6 ± 19.3 vs. 42.7 ± 16.9 min, p = 0.04), we set the cut-off points of Tmax at 60 min in men and at 75 min in women. In patients with FD, the prevalence of delayed gastric emptying was not different between men and women with the modified standard values of 13C-acetate breath test. (31.0 vs. 27.4%, p = 0.68). BMI was lower in the delayed gastric emptying group than in the non-delayed group among the male patients. Reflux symptoms were more severe in delayed gastric emptying group than in the non-delayed group among the female patients. The standard values of 13C-acetate breath test should be modified bearing the gender difference in mind. It provides us more appropriate information to understand the mechanisms of FD. © 2016 S.

Employment is a priority in the European Union, and it is essential to address the needs of individuals disadvantaged at the labour market on grounds such as ethnicity, age, gender or disability, to increase the opportunities for these groups to gain employment. The Council of the European Union recognize the important role of national organisations in increasing gender equality and the need to integrate a gender perspective in all policies. Gender equality perspectives should also, according to the EU Plan of Action and Gender Equality be integrated in education. To equip students in higher education with knowledge, about gender, age, disability and ethnicity in relation to employability, a European group initiated a project; Euro-Education: Employability for all (EEE4all). The project, funded by the European Lifelong Learning Programme, was aimed to develop and implement four course modules, each relating to employability with different focus: gender, age, disability or ethnicity. In this paper design, implementation, and evaluation of the course focused on gender, provided by the Occupational Therapy Programme at Linkoping University, is described. The students highlighted the importance of awareness and knowledge about gender theory and its application in relation to employability and client-centred approach.

The 10-item Center for the Epidemiological Studies of Depression Short Form (CES-D-10) is a widely used self-report measure of depression symptomatology. The aim of this study is to investigate the psychometric properties of the CES-D-10 in healthy community dwelling older adults. The sample consists of 19,114 community-based individuals residing in Australia and the United States who participated in the ASPREE trial baseline assessment. All individuals were free of any major illness at the time. We evaluated construct validity by performing confirmatory factor analysis, examined measurement invariance across country and gender followed by evaluating item discrimination bias in age, gender, race, ethnicity and education level, and assessing internal consistency. High item-total correlations and Cronbach's alpha indicated high internal consistency. The factor analyses suggested a unidimensional factor structure. Construct validity was supported in the overall sample, and by country and gender sub-groups. The CES-D-10 was invariant across countries, and although evidence of marginal gender non-invariance was observed there was no evidence of notable gender specific item discrimination bias. No notable differences in discrimination parameters or group membership measurement non-invariance were detected by gender, age, race, ethnicity, and education level. These findings suggest the CES-D-10 is a reliable and valid measure of depression in a volunteer sample. No noteworthy evidence of invariance and/or item discrimination bias is observed across gender, age, race, language and ethnic groups. Copyright © 2017 Elsevier Inc. All rights reserved.

Data from high-income countries suggest that women receive less intensive diagnostic and therapeutic management than men for acute coronary syndrome (ACS). There is a paucity of such data in the Indian population, which is 69% rural and prior studies focused mostly on urban populations. The objective of the present study was to identify the gender based differences in ACS management, if any, in a predominantly rural population. Data from 35 hospitals across Himachal Pradesh covering >90% of state population were collected for one year (July 2015-June 2016). A total of 2118 ACS subjects met inclusion criteria and baseline characteristics, in-hospital treatments and mortality rates were analyzed. Women constituted less than one-third of ACS population. Women were older compared to men and were more likely to present with NSTEMI/UA. Misinterpretation of initial symptoms and late presentation were also common in women. Fewer women received optimal guideline based treatment and PCI (0.9% vs 4.2%, p<0.01). Compare to men, women more often had Killip class >1 (27.3% vs 20.4%, p<0.01) and higher in-hospital mortality (8.5% vs 5.6%, p=0.009). On multivariate analysis the association between female gender and mortality was attenuated (adjusted odds ratio [OR]=1.36 [0.77-2.38]). The present study from India, is the first of its kind to evaluate the gender based differences among ACS patients, in a predominantly rural population. Our analysis demonstrates a significant gender based difference between symptom awareness and delay in presentation, management and in-hospital outcome. Further studies are warranted across other parts of country to investigate this gender disparity. Copyright © 2017 Elsevier B.V. All rights reserved.

The number of women pursuing training opportunities in neurological surgery has increased, although they are still underrepresented at senior positions relative to junior academic ranks. Research productivity is an important component of the academic advancement process. We sought to use the h-index, a bibliometric previously analyzed among neurological surgeons, to evaluate whether there are gender differences in academic rank and research productivity among academic neurological surgeons. The h-index was calculated for 1052 academic neurological surgeons from 84 institutions, and organized by gender and academic rank. Overall men had statistically higher research productivity (mean 13.3) than their female colleagues (mean 9.5), as measured by the h-index, in the overall sample (p<0.0007). When separating by academic rank, there were no statistical differences (p>0.05) in h-index at the assistant professor (mean 7.2 male, 6.3 female), associate professor (11.2 male, 10.8 female), and professor (20.0 male, 18.0 female) levels based on gender. There was insufficient data to determine significance at the chairperson rank, as there was only one female chairperson. Although overall gender differences in scholarly productivity were detected, these differences did not reach statistical significance upon controlling for academic rank. Women were grossly underrepresented at the level of chairpersons in this sample of 1052 academic neurological surgeons, likely a result of the low proportion of females in this specialty. Future studies may be needed to investigate gender-specific research trends for neurosurgical residents, a cohort that in recent years has seen increased representation by women.

The "inappropriately heavy placenta" has been considered to be associated with various pregnancy disorders; however, data is scarce what factors affect it. To determine whether the following three affect it; (1) infant gender and mother's parity, (2) growth restriction, and (3) preeclampsia. We employed fetal/placental weight ratio (F/P). Subjects consisted of 53,650 infants and their placentas from women who vaginally delivered singleton live term infants. First, we examined whether F/P differs among the infant's gender or mother's parity. We classified the population into 4 categories according to gender and parity: male, nulliparous (n=7,431), male, multiparous (n=7,859), female, nulliparous (n=7,559), female, multiparous (n=7,800), and, compared F/P among the four groups. Next, we determined whether F/P differs in "small" or "large" for gestational age (SGA or LGA) infants, compared with appropriate for gestational age infants. Last, we determined whether preeclampsia (representative disorder of SGA) affects F/P. (1) F/P significantly differed according to infant gender and parity: female and nulliparity had significantly smaller F/P. F/P was significantly smaller in (2) SGA infants, and (3) infants from preeclamptic mothers. We for the first time showed that in Japanese term vaginally-delivered singleton population, the following three had significantly smaller F/P than controls thus had "inappropriately heavy placenta": (1) female gender and nulliparity, (2) SGA infants, and (3) infants from preeclamptic mothers. We recommend that these factors should be taken into account in evaluating placental weight. These data may also be useful for further clarifying the fetal-placental pathophysiology in these conditions.

In the United States, black women are at much greater risk of obesity than are black men. Little is known about the factors underlying this disparity. We explored whether childhood sociodemographic factors (parental education, single-mother household, number of siblings, number of minors in household, birth order, and female caregiver's age) were associated with the gender disparity in obesity prevalence in young black adults in the United States. An analytic data set (n = 7747) was constructed from the nationally representative National Longitudinal Study of Adolescent Health. Childhood sociodemographic factors were assessed in 1994-1995 in nonimmigrant black and white youths aged 11-19 y. Obesity was assessed in 2001-2002. For each childhood sociodemographic factor, we evaluated whether the prevalence difference (female obesity minus male obesity) was modified by the factor. We described the contribution of each variable category to the overall prevalence difference. In unadjusted and multivariable-adjusted models, parental education consistently modified gender disparity in blacks (P = 0.01). The gender gap was largest with low parental education (16.7% of men compared with 45.4% of women were obese) and smallest with high parental education (28.5% of men compared with 31.4% of women were obese). In whites, there was little overall gender difference in obesity prevalence. To our knowledge, this was the first study to document that the gender disparity in obesity prevalence in young black adults is concentrated in families with low parental education. In these low-socioeconomic-status families, obesity development is either under the control of distinct mechanisms in each gender, or men and women from these households adopt different obesity-related behaviors.

Abstract Background Morbidity and mortality for women with chronic obstructive pulmonary disease (COPD) are increasing, and little is known about gender differences in perception of COPD care. Methods Surveys were administered to a convenience sample of COPD patients to evaluate perceptions about symptoms, barriers to care, and sources of information about COPD. Results Data on 295 female and 273 male participants were analyzed. With similar frequencies, women and men reported dyspnea and rated their health as poor/very poor. Although more women than men reported annual household income <$30,000, no significant gender differences in frequency of health insurance, physician visits, or ever having had spirometry were detected. In adjusted models (1) women were more likely to report COPD diagnostic delay (odds ratio [OR] 1.66, 95% confidence interval [CI] 1.13-2.45, p=0.01), although anxiety (OR 1.83, 95% CI 1.10-3.06, p=0.02) and history of exacerbations (OR 1.60, 95% CI 1.08-2.37, p=0.01) were also significant predictors, (2) female gender was associated with difficulty reaching one's physician (OR 2.54, 95% CI 1.33-4.86, p=0.004), as was prior history of exacerbations (OR 2.25, 95% CI 1.21-4.20, p=0.01), and (3) female gender (OR 2.15, 95% CI 1.10-4.21, p=0.02) was the only significant predictor for finding time spent with their physician as insufficient. Conclusions Significant gender-related differences in the perception of COPD healthcare delivery exist, revealing an opportunity to better understand what influences these attitudes and to improve care for both men and women.

Studies comparing gender-specific outcomes in patients with atrial fibrillation (AF) have reported conflicting results. Gender differences in cerebrovascular accident/systemic embolism (CVA/SE) or major bleeding outcomes with novel oral anticoagulant (NOAC) use are not known. The goal of this analysis was to perform a systematic review and meta-analysis evaluating gender differences in residual risk of CVA/SE and major bleeding outcomes in patients with nonvalvular AF treated with either warfarin or NOAC. Sixty-four randomized studies were identified using keywords "gender," "AF," and "CVA." Using the Preferred Reporting Items for Systemic Reviews and Meta-analysis method, 6 studies met criteria for inclusion in this meta-analysis. CVA/SE and major bleeding outcomes were separately analyzed in cohorts receiving warfarin and NOAC agents, comparing men with women. Women with AF taking warfarin were at a significantly greater residual risk of CVA/SE compared with men (odds ratio 1.279, 95% confidence interval 1.111 to 1.473, Z = -3.428, p = 0.001). No gender difference in residual risk of CVA/SE was noted in patients with AF receiving NOAC agents (odds ratio 1.146, 95% confidence interval 0.97 to 1.354, p = 0.109). Major bleeding was less frequent in women with AF treated with NOAC. In conclusion, women with AF treated with warfarin have a greater residual risk of CVA/SE and an equivalent major bleeding risk, whereas those treated with NOAC agents deemed superior to warfarin are at equivalent residual risk of CVA/SE and less major bleeding risk compared with men. These results suggest an increased net clinical benefit of NOAC agents compared with warfarin in treating women with AF. Copyright © 2014 Elsevier Inc. All rights reserved.

Background Self-management is the cornerstone of diabetes control and prevention of complications; however, it is undetermined whether differences in intention to adopt healthy lifestyles and actual healthy behavior exist across race/ethnic groups. This study evaluated the differences across racial-ethnic groups in self-reported medical advice received and health intentions and behaviors among adults with type 2 diabetes mellitus. Methods A cross-sectional analysis of the 2007 SHIELD US survey ascertained self-reported health intentions and behaviors for regular exercise, diet, and weight management among Non-Hispanic Caucasian (n = 2526), Non-Hispanic African-American (n = 706), and Hispanic (n = 179) respondents with type 2 diabetes. Results A similar proportion of respondents from each race-gender group (43%-56%) reported receiving healthcare advice to increase their exercise (P = 0.32). Significantly more minorities reported an intention to follow the exercise recommendation compared with Non-Hispanic Caucasians (P = 0.03). More Non-Hispanic African-American (29%) and Hispanic (27%) men reported exercising regularly compared with other race-gender groups (P = 0.02). Significantly more Non-Hispanic Caucasian women (74%) and Hispanic women (79%) reported trying to lose weight compared with other groups (P < 0.0001). Conclusions Differences in health intentions and healthy behaviors were noted across race-gender groups. More Non-Hispanic African-American men reported an intention to follow advice on exercising and self-report of exercising regularly was also higher compared with other race-gender groups. More Hispanic men reported high physical activity levels than other groups. Despite an increased willingness to follow healthcare recommendations for diet, >50% of respondents were obese among all race-gender groups. PMID:21729303

Women in medical physics: a preliminary analysis of workforce and research participation in Australia and New Zealand.

Although the participation of women within the science, technology, engineering and mathematics workforces has been widely discussed over recent decades, the recording and analysis of data pertaining to the gender balance of medical physicists in Australia and New Zealand remains rare. This study aimed to provide a baseline for evaluating future changes in workforce demographics by quantifying the current level of representation of women in the Australasian medical physics workforce and providing an indication of the relative contribution made by those women to the local research environment. The 2015 Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM) member directory and list of chief physicists at ACPSEM-accredited radiation oncology and diagnostic imaging training centres were interrogated to identify the gender balance of medical physicists working in Australia and New Zealand. A specific investigation of the employment levels of all medical physicists in Queensland was undertaken to provide an example of the gender balance at different levels of seniority in one large Australian state. Lists of authors of medical physics presentations at ACPSEM annual conferences and authors of publications in the ACPSEM's official journal, were used to provide an indication of the gender balance in published research within Australia and New Zealand. The results of this study showed that women currently constitute approximately 28 % of the medical physics workforce in Australia and New Zealand, distributed disproportionally in junior roles; there is a decrease in female participation in the field with increasing levels of seniority, which is particularly apparent in the stratified data obtained for the Queensland workforce. Comparisons with older data suggest that this situation has changed little since 2008. Examination of ACPSEM conference presentations suggested that there are similar disparities between the gender-balance of proffered and invited or keynote speakers (28 % and 13 % from female authors) and the gender balance of certified and chief physicists (28 % and 21 % female). The representation of women in the ACPSEM journal does not differ substantially between authorship of proffered versus invited work (22 % and 19 % from female authors). While this work was limited to evaluating the membership, annual conference and official journal of the ACPSEM (rather than evaluating the entire medical physics workforce and the contributions of male and female physicists to international conferences and publications), this study nonetheless led to the following recommendations: that a longitudinal study analysing correlations between age, period of service, seniority and gender should be undertaken and that future ACPSEM workforce surveys should include analyses of gender representation.

This study was carried out to quantify and compare the quantitative image quality of coronary computed tomography angiography (CCTA) between genders as well as between different tube voltages scan protocols. Fifty-five cases of CCTA were collected retrospectively and all images including reformatted axial images at systolic and diastolic phases as well as images with curved multi planar reformation (cMPR) were obtained. Quantitative image quality including signal intensity, image noise, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of right coronary artery (RCA), left anterior descending artery (LAD), left circumflex artery (LCx) and left main artery (LM) were quantified using Analyze 12.0 software. Six hundred and fifty-seven coronary arteries were evaluated. There were no significant differences in any quantitative image quality parameters between genders. 100 kilovoltage peak (kVp) scanning protocol produced images with significantly higher signal intensity compared to 120 kVp scanning protocol (P<0.001) in all coronary arteries in all types of images. Higher SNR was also observed in 100 kVp scan protocol in all coronary arteries except in LCx where 120 kVp showed better SNR than 100 kVp. There were no significant differences in image quality of CCTA between genders and different tube voltages. Lower tube voltage (100 kVp) scanning protocol is recommended in clinical practice to reduce the radiation dose to patient.

The objective of this trial was to evaluate the effect of gender on strength gains after five week training programme that consisted of isometric exercise coupled with electromyographic biofeedback to the quadriceps muscle. Forty-three (20 men and 23 women) patients with knee osteoarthritis (OA), were placed into two groups based on their gender. Both groups performed isometric exercise coupled with electromyographic biofeedback for five days a week for five weeks. Both groups reported gains in muscle strength after five week training. However, the difference was found to be statistically insignificant between the two groups (P=0.224). The results suggest that gender did not affect gains in muscle strength by isometric exercise coupled with electromyographic biofeedback in patients with knee OA.

In oculoplastic operations, knowledge of the dimensions of periorbital features based on age, gender, and race is essential for achieving better aesthetic result. This article seeks to determine the racial and gender differences of periorbital features among Malaysian Malay (MM), Malaysian Indian (MI), and Malaysian Chinese (MI) subjects. Evaluation of periorbital features was done on photographs of 200 MM, 200 MI, and 200 MC subjects, aged 18 to 26 years. The measured values were evaluated by an independent t -test. A significant difference was found between MM and MI in all measurements except interbrow distance in males, eyebrow thickness in females, and apex to lateral limbus distance in both sexes. Between MI and MC the difference was insignificant for interbrow distance in male groups, apex to lateral limbus distance in females, and palpebral fissure inclination and eyebrow apex angle in both sexes. Between MM and MC, significant differences were found for eyebrow thickness and medial canthus tilt in female group. Male groups showed significant difference for apex to lateral limbus and lateral canthus distance and eyebrow apex angle. Eyebrow height, palpebral fissure width, and intercanthal distance were significantly different in both sexes. Sexual dimorphism was found for all measurements in MI, but MM and MC showed insignificant difference for eyebrow apex angle. Four types of epicanthus were observed in MM and MC and three types in MI. Eyebrow apex between lateral limbus and lateral canthus was the most common position in all racial groups. Significant racial and gender differences exist for certain periorbital measurements. The knowledge of these differences is expected to influence the surgical outcome.

Differential responses in terms of gender and antisocial behaviour in emotional reactivity to affective pictures using the International Affective Picture System (IAPS) have been demonstrated in adult and adolescent samples. Moreover, a quadratic relationship between the arousal (intensity) and valence (degree of unpleasantness) has been suggested. The picture perception methodology has rarely been applied to middle school-aged children. We examined the subjective ratings of emotional reactivity in children for: i) the relationship between arousal and valence, ii) gender differences, and iii) its association with measures of antisocial behaviour. Twenty-seven IAPS pictures were selected to cover a wide range of affective content and were individually administered to a non-referred community sample of 659 7-11-year-old children using a paper-and-pencil version. Concurrent symptoms of conduct disorder, oppositional defiance and psychopathy were collected from multiple sources (teacher-, parent- and self-report). A quadratic relationship between arousal and valence, similar to that previously reported in adults, was demonstrated. A gender difference was found for valence ratings, with girls rating aversive pictures more unpleasant than boys. No gender differences for arousal ratings were found. A significant difference was found between groups scoring above and below cut-off scores on measures of antisocial behaviour. Children above cut-off reported lower arousal to unpleasant pictures, but higher arousal to pleasant pictures. We confirmed that a paper-and-pencil version of the IAPS for evaluating emotion response to affectively valent and arousing stimuli can be used in school settings and that comparable gender differences in emotional reactivity can be found in children. The differential emotional reactivity of children above cut-off on measures of antisocial behaviour suggested these symptoms to be associated with a combination of increased reward and decreased punishment sensitivity.

We evaluated gender-differences in quality of type 1 diabetes (T1DM) care. Starting from electronic medical records of 300 centers, 5 process indicators, 3 favorable and 6 unfavorable intermediate outcomes, 6 treatment intensity/appropriateness measures and an overall quality score were measured. The likelihood of women vs. men (reference class) to be monitored, to reach outcomes, or to be treated has been investigated through multilevel logistic regression analyses; results are expressed as Odd Ratios (ORs) and 95% confidence intervals (95%CIs). The inter-center variability in the achievement of the unfavorable outcomes was also investigated. Overall, 28,802 subjects were analyzed (45.5% women). Women and men had similar age (44.5±16.0 vs. 45.0±17.0 years) and diabetes duration (18.3±13.0 vs. 18.8±13.0 years). No between-gender differences were found in process indicators. As for intermediate outcomes, women showed 33% higher likelihood of having HbA1c ≥8.0% (OR = 1.33; 95%CI: 1.25-1.43), 29% lower risk of blood pressure ≥140/90 mmHg (OR = 0.71; 95%CI: 0.65-0.77) and 27% lower risk of micro/macroalbuminuria (OR = 0.73; 95%CI: 0.65-0.81) than men, while BMI, LDL-c and GFR did not significantly differ; treatment intensity/appropriateness was not systematically different between genders; overall quality score was similar in men and women. Consistently across centers a larger proportion of women than men had HbA1c ≥8.0%, while a smaller proportion had BP ≥140/90 mmHg. No gender-disparities were found in process measures and improvements are required in both genders. The systematic worse metabolic control in women and worse blood pressure in men suggest that pathophysiologic differences rather than the care provided might explain these differences.

Women's participation in the professions is steadily increasing. This study is a quantitative assessment of male and female career patterns in dentistry and of the role of marriage in any gender gap. A 1997 survey explored the professional activity of Flemish dentists. There is no educational disparity between dentists, female dentists enter the profession on an equal footing with their male colleagues. Therefore any other career influencing factors reveal themselves relatively clearly. Dependent variable was income; independent variables were gender and marriage. Female dentists scored lower than male dentists in each career phase; marriage made no significant difference. However, marriage turned out to be an important positive factor in the career of male dentists. Women dentists marry significantly later and less than their male colleagues. Further research, also of a qualitative nature, is necessary to evaluate the professional and social impact of this substantial gender difference.
From genius inverts to gendered intelligence: Lewis Terman and the power of the norm.

PubMed

Hegarty, Peter

2007-05-01

The histories of "intelligence" and "sexuality" have largely been narrated separately. In Lewis Terman's work on individual differences, they intersect. Influenced by G. Stanley Hall, Terman initially described atypically accelerated development as problematic. Borrowing from Galton, Terman later positioned gifted children as nonaverage but ideal. Attention to the gifted effeminate subjects used to exemplify giftedness and gender nonconformity in Terman's work shows the selective instantiation of nonaverageness as pathological a propos of effeminacy, and as ideal a propos of high intelligence. Throughout, high intelligence is conflated with health, masculinity, and heterosexuality. Terman's research located marital sexual problems in women's bodies, further undoing possibilities for evaluating heterosexual men's practices as different from a normative position. Terman's research modernized Galton's imperialist vision of a society lead by a male cognitive elite. Psychologists continue to traffic in his logic that values and inculcates intelligence only in the service of sexual and gender conformity.

At the start of gender reassignment therapy, persons with a gender identity disorder (GID) may deal with various forms of psychopathology. Until now, a limited number of publications focus on the effect of the different phases of treatment on this comorbidity and other psychosocial factors. The aim of this study was to investigate how gender reassignment therapy affects psychopathology and other psychosocial factors. This is a prospective study that assessed 57 individuals with GID by using the Symptom Checklist-90 (SCL-90) at three different points of time: at presentation, after the start of hormonal treatment, and after sex reassignment surgery (SRS). Questionnaires on psychosocial variables were used to evaluate the evolution between the presentation and the postoperative period. The data were statistically analyzed by using SPSS 19.0, with significance levels set at P < 0.05. The psychopathological parameters include overall psychoneurotic distress, anxiety, agoraphobia, depression, somatization, paranoid ideation/psychoticism, interpersonal sensitivity, hostility, and sleeping problems. The psychosocial parameters consist of relationship, living situation, employment, sexual contacts, social contacts, substance abuse, and suicide attempt. A difference in SCL-90 overall psychoneurotic distress was observed at the different points of assessments (P = 0.003), with the most prominent decrease occurring after the initiation of hormone therapy (P < 0.001). Significant decreases were found in the subscales such as anxiety, depression, interpersonal sensitivity, and hostility. Furthermore, the SCL-90 scores resembled those of a general population after hormone therapy was initiated. Analysis of the psychosocial variables showed no significant differences between pre- and postoperative assessments. A marked reduction in psychopathology occurs during the process of sex reassignment therapy, especially after the initiation of hormone therapy. © 2013 International Society for Sexual Medicine.

This study examined the size of differences in self-reported family, marital, and gender-role values in five cultural groups in the Netherlands (6338 Dutch mainstreamers and 422 Turkish, 369 Moroccan, 429 Surinamese, and 394 Antillean first- and second-generation immigrants). It was found that the three value scales were neither completely independent, nor could they be merged into a single value scale. The factor structures of all scales were identical for the five cultural groups, implying that the concepts can be compared. Age, sex, and notably education accounted for a substantial part of the cultural differences in all values. Cultural differences were larger for marital and family values than for gender-role values. Family and marital values yielded the same rank order of mean scores in the five cultural groups: Turks and Moroccans scored the lowest (having the most traditional values), followed by Surinamers, Antilleans, and Dutch mainstreamers. This rank order corresponds with the ethnic hierarchy of cultural groups that is based on the evaluation of ethnic groups by mainstreamers according to their liking of and likeness to ethnic groups. Generational differences were not found for family and gender-role values but first-generation immigrants in all groups had more traditional marital values than had second-generation immigrants. It was concluded that the theoretical framework based on a combination of three Hofstede dimensions (individualism-collectivism, power-distance, and femininity-masculinity), a model of the hierarchy of the ethnic groups in the Dutch society, and acculturation theory provided an adequate way to address family, marital, and gender-role value differences in the five cultural groups.

Failure of an instructor to meet gender or age-based expectations can translate to lower scores or negative comments on evaluations. While there is some evidence of bias in students' evaluations of online instructors,…

To evaluate the effect of gender on clinical outcomes in people with type 2 diabetes mellitus (T2DM) receiving antidiabetes therapy. This is a pooled analysis from nine similarly designed phase 3 and 4 randomized, controlled studies evaluating insulin glargine and an active comparator (NPH insulin, insulin lispro, premixed insulin, oral antidiabetes drugs, dietary intervention) in adults with T2DM. Impact of gender on outcomes including HbA1c, fasting plasma glucose (FPG), weight-adjusted insulin dose, and hypoglycemia incidence was evaluated after 24 weeks of treatment. Overall, 1651 male and 1287 female individuals were included; 49.8% and 50.2% were treated with insulin glargine or comparators, respectively. Females receiving insulin glargine were less likely than males to achieve a glycemic target of HbA1c≤7.0% (53mmol/mol) (54.3% vs 60.8%, respectively, p=0.0162); there was no difference between females and males receiving comparators (52.7% vs 51.3%, respectively, p=0.4625). Females had significantly greater reductions in FPG (3.1mg/dL, p=0.0458), required significantly higher insulin doses (0.03IU/kg, p=0.0071), and had significantly higher annual rates of symptomatic (p<0.0001), glucose-confirmed (<50 and <70mg/dL) symptomatic (p=0.0005 and p<0.0001), and severe hypoglycemia (p=0.0020) than males. Females in this analysis had smaller reductions in HbA1c and were less likely to reach glycemic goals despite higher insulin doses and more hypoglycemic events than males. Differences in gender responses to therapy should be considered when individualizing treatment for people with T2DM. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Gender is associated to lifetime risk of mood disorders, women having the highest lifetime and 12-month prevalence. In Mexico one out of five individuals with any mood disorder receives treatment during the first year. We evaluate the ages at which women and men are more vulnerable for the first onset of a major depressive episode, the longest duration and greatest number of episodes, the areas of daily functioning most affected, and which variables predict whether or not a person receives any kind of treatment. The Mexican National Comorbidity Survey, as part of the World Mental Health Surveys Initiative, is based on a stratified, multistage area probability Mexican urban household sample aged 18 to 65 (n=5782). Wald X(2) tests were performed to evaluate gender and cohort differences; logistic regression models were performed to evaluate gender and cohort as treatment predictors. The most vulnerable group is the cohort of 45-54 year-old women. Once a first episode occurs, there are no sex differences in terms of number or length of episodes. There is a gap in service use, especially among 18-29 year-old women; the oldest women are the most impaired. Individuals from rural communities are not represented and there may have been recall bias due to the retrospective design. Efforts should focus on factors related to the first onset episode and on early treatment programs to reduce the risk of subsequent episodes. Research and health resources should attend to the most vulnerable group, and the youngest women, who are in the reproductive age and have the largest treatment gap. Copyright Â© 2011 Elsevier B.V.

Diabetes is the most common cause of non-traumatic lower limb amputations and cardiovascular diseases. However, only a negligible percentage of the patients and subjects knew that the feet are affected in diabetes and diabetes affects the heart. Hence, a cross-sectional study was carried out to evaluate the knowledge of diabetes mellitus among the public of different age group, gender, ethnicity, and education level. A sample of 400 participants was randomly selected and data was collected using a structured questionnaire under non-contrived setting. The results showed that there is a statistically significant difference in knowledge on diabetes mellitus among different age groups and different ethnic origin but there is no significant difference in the knowledge among different gender and education level. Out of 400 respondents, 284 respondents (71%) knew that diabetes mellitus is actually a condition characterized by raised blood sugar. Age and education level of respondents were found to be the predominant predictive factors on diabetes knowledge, whereas the gender of respondents did not affect the findings of this study. An improved and well-structured educational programme that tackles the areas of weaknesses should be recommended to increase the level of knowledge on diabetes among Malaysians.
Internal Structure and Partial Invariance across Gender in the Spanish Version of the Reasoning Test Battery.

The Reasoning Test Battery (BPR) is an instrument built on theories of the hierarchical organization of cognitive abilities and therefore consists of different tasks related with abstract, numerical, verbal, practical, spatial and mechanical reasoning. It was originally created in Belgium and later adapted to Portuguese. There are three forms of the battery consisting of different items and scales which cover an age range from 9 to 22. This paper focuses on the adaptation of the BPR to Spanish, and analyzes different aspects of its internal structure: (a) exploratory item factor analysis was applied to assess the presence of a dominant factor for each partial scale; (b) the general underlined model was evaluated through confirmatory factor analysis, and (c) factorial invariance across gender was studied. The sample consisted of 2624 Spanish students. The results concluded the presence of a general factor beyond the scales, with equivalent values for men and women, and gender differences in the factorial structure which affect the numerical reasoning, abstract reasoning and mechanical reasoning scales.

Coronary heart disease is the most common cause of death worldwide. In the United Kingdom in 2010, over 80,000 deaths were attributed to coronary heart disease, and one in 10 female deaths were due to coronary heart disease. Acute coronary syndrome, a subset of coronary heart disease, was responsible for 175,000 inpatient admissions in the United Kingdom in 2012. While men have traditionally been considered to be at higher risk of acute coronary syndrome, various studies have demonstrated that women often suffer from poorer outcomes following an adverse cardiovascular event. This gap is gradually narrowing with the introduction of advanced interventional strategies and pharmacotherapy. However, a better understanding of these differences is of crucial importance for the improvement of the pharmacological and interventional management of acute coronary syndrome and for the development of possible new gender-specific diagnostic and therapeutic options. The goals of this review are to evaluate gender differences in outcomes in patients with acute coronary syndrome in the current era and identify potential mechanisms behind these differences in outcomes following percutaneous coronary intervention.

This study examined gender differences within Black, Latino, and White subgroups in the utilization of comprehensive services and their relation to posttreatment substance use. Survey data were collected during the National Treatment Improvement Evaluation Study (NTIES), a prospective, longitudinal, multisite study of substance abuse treatment programs and their clients in the United States. The analytic sample consisted of 1,812 Blacks (734 women and 1,078 men), 486 Latinos (147 women and 339 men), and 844 Whites (147 women and 339 men) from 59 service delivery organizations. Results related to service utilization indicated that compared to men, women in all racial and ethnic groups needed and received more services targeted to their needs and reported more positive relations with service providers. Gender was a significant moderator of the relationship between service receipt and treatment outcomes for all racial and ethnic groups, but especially for the Latino subsample. Findings point to the need to consider race-specific gender differences in the development of culturally competent, comprehensive substance abuse treatment. PMID:24560127
Quantitative evaluation of gender bias in astronomical publications from citation counts

Caplar, Neven; Tacchella, Sandro; Birrer, Simon

2017-06-01

Numerous studies across different research fields have shown that both male and female referees consistently give higher scores to work done by men than to identical work done by women 1,2,3 . In addition, women are under-represented in prestigious publications and authorship positions 4,5 and women receive ~10% fewer citations 6,7 . In astronomy, similar biases have been measured in conference participation 8,9 and success rates for telescope proposals 10,11 . Even though the number of doctorate degrees awarded to women is constantly increasing, women still tend to be under-represented in faculty positions 12 . Spurred by these findings, we measure the role of gender in the number of citations that papers receive in astronomy. To account for the fact that the properties of papers written by men and women differ intrinsically, we use a random forest algorithm to control for the non-gender-specific properties of these papers. Here we show that papers authored by women receive 10.4 ± 0.9% fewer citations than would be expected if the papers with the same non-gender-specific properties were written by men.

Data on the effect of gender in rheumatoid arthritis (RA) in non-Caucasian populations is scarce. Latin America and the Caribbean (LAC) is a large population with unique characteristics, including high admixture. Our aim was to examine the effect of gender in patients with RA in LAC. This was a 2-phase study. First we conducted a cross-sectional and analytical study in which 1128 consecutive Colombian patients with RA were assessed. Second, a systematic review of the literature was done to evaluate the effect of gender in LAC patients with RA. Our results show a high prevalence of RA in LAC women with a ratio of 5.2 women per man. Colombian women with RA are more at risk of having an early age at onset and developing polyautoimmunity and abdominal obesity, and they perform more household duties than their male counterparts. However, male gender was associated with the presence of extra-articular manifestations. Of a total of 641 potentially relevant articles, 38 were considered for final analysis, in which several factors and outcomes related to gender were identified. RA in LAC women is not only more common but presents with some clinical characteristics that differ from RA presentation in men. Some of those characteristics could explain the high rates of disability and worse prognosis observed in women with RA in LAC. Copyright © 2012 Elsevier HS Journals, Inc. All rights reserved.

Dopamine transporter (DAT) imaging with [(123)I]FP-CIT (DaTSCAN) is an established diagnostic tool in parkinsonism and dementia. Although qualitative assessment criteria are available, DAT quantification is important for research and for completion of a diagnostic evaluation. One critical aspect of quantification is the availability of normative data, considering possible age and gender effects on DAT availability. The aim of the European Normal Control Database of DaTSCAN (ENC-DAT) study was to generate a large database of [(123)I]FP-CIT SPECT scans in healthy controls. SPECT data from 139 healthy controls (74 men, 65 women; age range 20-83 years, mean 53 years) acquired in 13 different centres were included. Images were reconstructed using the ordered-subset expectation-maximization algorithm without correction (NOACSC), with attenuation correction (AC), and with both attenuation and scatter correction using the triple-energy window method (ACSC). Region-of-interest analysis was performed using the BRASS software (caudate and putamen), and the Southampton method (striatum). The outcome measure was the specific binding ratio (SBR). A significant effect of age on SBR was found for all data. Gender had a significant effect on SBR in the caudate and putamen for the NOACSC and AC data, and only in the left caudate for the ACSC data (BRASS method). Significant effects of age and gender on striatal SBR were observed for all data analysed with the Southampton method. Overall, there was a significant age-related decline in SBR of between 4 % and 6.7 % per decade. This study provides a large database of [(123)I]FP-CIT SPECT scans in healthy controls across a wide age range and with balanced gender representation. Higher DAT availability was found in women than in men. An average age-related decline in DAT availability of 5.5 % per decade was found for both genders, in agreement with previous reports. The data collected in this study may serve as a reference database for nuclear medicine centres and for clinical trials using [(123)I]FP-CIT SPECT as the imaging marker.

Cystic echinococcosis (CE) is a public health problem in countries having such endemic areas. Epidemiological studies of CE, especially pediatric, are rare. The aim of this study was to evaluate epidemiological and clinical characteristics of CE in children in Serbia. Data were obtained retrospectively from the case records of patients under the age of 18 years admitted for surgical treatment of CE at two large pediatric medical institutions in the period 1990-2006. Patients' age, number of cysts and their anatomic location were evaluated in relation to differences by patients' gender and socio-geographic status (urban or rural origin). The study included 149 children with 272 hydatid cysts. The mean age of patients was 10.1+/-3.8 years. There were no significant differences in the number of patients in relation to gender and urban:rural origin. There were no significant differences in patients' age at the time of surgery or the number of cysts per patient when patients' gender or socio-geographic status was evaluated. The anatomic location of cysts was as follows: liver (N=165; 60.7%), lungs (N=82; 30.1%), and other locations (N=25; 9.2%). Multiple cysts, and combined liver/lung involvement were identified in 34.2% (N=51), and 6.0% (N=9) of patients, respectively. Hepatic cysts were significantly more common in girls than in boys. There were no significant differences in anatomic location of cysts between socio-geographic groups. The large number of infected children during a long period of investigation indicates an active transmission of disease and a lack of program for control and prevention of CE in Serbia.
Assessing implicit gender bias in Medical Student Performance Evaluations.

For medical schools, the increasing presence of women makes it especially important that potential sources of gender bias be identified and removed from student evaluation methods. Our study looked for patterns of gender bias in adjective data used to inform our Medical Student Performance Evaluations (MSPEs). Multigroup Confirmatory Factor Analysis (CFA) was used to model the latent structure of the adjectives attributed to students (n = 657) and to test for systematic scoring errors by gender. Gender bias was evident in two areas: (a) women were more likely than comparable men to be described as ''compassionate,'' ''sensitive,'' and ''enthusiastic'' and (b) men were more likely than comparable women to be seen as ''quick learners.'' The gender gap in ''quick learner'' attribution grows with increasing student proficiency; men's rate of increase is over twice that of women's. Technical and nontechnical approaches for ameliorating the impact of gender bias on student recommendations are suggested.

The purpose of this study was to investigate the morphology and calcification pattern of the styloid process (SP) and to determine their relations with subjects' age, gender, and dental status. 910 panoramic radiographs were stratified by age, dental status and gender. The distance between the points where SP leaves the tympanic plate of the temporal bone and the bony tip of SP was measured. Calcification patterns were classified as : (A) Region 1, tympanohyal alone (B) Region 2, stylohyal alone (C) Region 1 and 2, separate (D) Regions 1 and 2, continuous (E) Regions 1, 2, and 3, continuous (F) Regions 1, 2, and 3, separate (G) Regions 1 and 2, continuous, but separate from 3 (H) Regions 2 and 3, separate (I) Regions 2 and 3, continuous, but separate from 1 (J) Region 3 alone (K) Region 3 and 4, continuous (may include calcification in one other region) (L) No styloid process visible. The right SPs were found to be longer than the left (p<0.05). Types D (right 42.9%, left 42%) and E (right 33.3%, left 30.8%) were the most common morphological calcifications on both sides. No statistical difference was found for bilateral SP length between gender, age, and dental status groups. A significant difference was found only for right SP morphological calcification types as to age groups in both genders (p<0.05). No significant difference was found for SP morphological calcification types according to gender and dental status. The morphological types are formed at their present area. Even though SP calcification type was determined according to the length of SP, age was not an effective factor on the length, but the morphological calcification type of SP. Therefore, factors other than age may have a role in the development of morphological calcification types. Structural characteristics of SP are not associated with age, gender and dental status.

Malnutrition is common in patients undergoing haemodialysis (HD). Several studies have described different nutritional parameters as mortality predictors but few have studied whether there are differences between genders. This study aimed to evaluate which nutrition parameters may be associated with mortality in patients undergoing long-term HD depending on their gender. Longitudinal prospective multicentre study with 12 months of follow-up. Anthropometric and laboratory measures were obtained from 697 patients. Men who died were older, had lower dry weight, body mass index, potassium, phosphorus and albumin, compared with male patients who survived. Female patients who died had lower albumin and nPCR compared with survivors. Kaplan-Meier analysis displayed a significantly worse survival in patients with albumin <3.5 g/dl in both genders and with body mass index <23 kg/m 2 in men. In the Cox regression analysis patients overall mortality was related to body mass index <23 kg/m 2 , potassium ≤5.5 mEq/l and phosphorus <3.0 mg/dl for male patients and albumin <3.5 g/dl and normalised protein catabolic rate (nPCR) <0.8 g/kg/day for both genders. Associations between albumin, body mass index and mortality risk continued to be significant after adjustments for age, length of time on dialysis and diabetes for males. However, in women, only albumin persisted as an independent predictor of death. Depending on the gender, different parameters such as protein intake, potassium, phosphorus, body mass index and albumin are associated with mortality in patients undergoing HD. Albumin <3.5 g/dl is an independent mortality predictor in both genders, whereas a body mass index <23 kg/m 2 is an independent predictor of death, but only in men. © 2017 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Introduction: The purpose of this study was to investigate the root and canal morphology of maxillary first molars with regards to patients’ age and gender with cone-beam computed tomography (CBCT). Methods and Materials: A total of 149 CBCT scans from 92 (67.1%) female and 57 (31.3%) male patients with mean age of 40.5 years were evaluated. Tooth length, presence of root fusion, number of the roots and canals, canal types based on Vertucci’s classification, deviation of root and apical foramen in coronal and sagittal planes and the correlation of all items with gender and age were recorded. The Mann Whitney U, Kruskal Wallis and Fisher’s exact tests were used to analyze these items. Results: The rate of root fusion was 1.3%. Multiple canals were present in the following frequencies: four canals 78.5%, five canals 11.4% and three canals 10.1%. Additional canal was detected in 86.6% of mesiobuccal roots in which Vertucci’s type VI configuration was the most prevalent followed by type II and I. Type I was the most common one in distobuccal and palatal roots. There was no statistically significant difference in the canal configurations in relation to gender and age as well as the incidence root or canal numbers (P>0.05). The mean tooth length was 19.3 and 20.3 mm in female and male patients, respectively which was statistically significant (P<0.05). Evaluation of root deviation showed that most commonly, a general pattern of straight-distal in the mesiobuccal and straight-straight for distobuccal and palatal roots occurred. In mesiobuccal roots, straight and distal deviations were more dominant in male and female, respectively (P<0.05). The prevalence of apical foramen deviation in mesiobuccal and palatal roots statistically differed with gender. Conclusion: The root and canal configuration of Iranian population showed different features from those of other populations. PMID:27790259

A smaller knee flexion angle and larger knee valgus angle during weight-bearing activities have been identified as risk factors for non-contact anterior cruciate ligament (ACL) injuries. To prevent such injuries, attention has been focused on the role of hip strength in knee motion control. However, gender differences in the relationship between hip strength and knee kinematics during weight-bearing activities in the frontal plane have not been evaluated. The purpose of this study was to determine the influence of hip strength on knee kinematics in both genders during a single-legged landing task in the frontal plane. The hypotheses were that 1) subjects with a greater hip strength would demonstrate larger knee flexion and smaller knee valgus and internal rotation angles and 2) no gender differences would exist during the single-legged landing task. Forty-three Japanese collegiate basketball players (20 males, 23 females) participated in this study. Three-dimensional motion analysis was used to evaluate knee kinematics during a single-legged medial drop landing (SML). A hand-held dynamometer was used to assess hip extensor (HEXT), abductor (HAB), and external rotator (in two positions: seated position [SHER] and prone [PHER]) isometric strength. Spearman rank correlation coefficients (ρ) were determined for correlations between hip strength and knee kinematics at initial contact (IC) and peak (PK) during SML (p < 0.05). Negative correlations were observed between the knee valgus angle at IC and HEXT (ρ = -0.48, p = 0.02), HAB (ρ = -0.46, p = 0.03) and PHER (ρ = -0.44, p = 0.04) strength in females. In addition, a significant positive correlation was observed between the knee flexion angle at PK and HEXT strength (ρ = 0.61, p = 0.004) in males. Significant correlations between hip strength and knee kinematics during SML were observed in both genders. Hip strength may, therefore, play an important role in knee motion control during sports activities, suggesting that increased hip strength may help to prevent non-contact ACL injuries in athletes of both genders. Moreover, gender-specific programs may be needed to control abnormal knee motion, as the influence of hip strength on knee kinematics may differ based on gender. 3.

This article assesses the effects of comprehensive tobacco control policies on diverse subpopulations of girls and women who are at increased vulnerability to tobacco use because of disadvantage. The authors report on a recent assessment of experimental literature examining tobacco taxation; smoking location restrictions in public and private spaces; and sales restrictions. A comprehensive search was undertaken to identify relevant studies and evaluation reports. Gender based and diversity analyses were performed to identify pertinent sex differences and gender influences that would affect the application and impact of the policy. Finally, the results were contextualised within the wider literature on women's tobacco use and women's health. The authors consider not only the intended policy effects, but also explicitly examine the gendered and/or unintended consequences of these policies on other aspects of girls and women's health and wellbeing. A framework for developing gender sensitive tobacco programmes and policies for low income girls and women is provided.

The current review gives an overview of brain studies in transgender people. First, we describe studies into the aetiology of feelings of gender incongruence, primarily addressing the sexual differentiation hypothesis: does the brain of transgender individuals resemble that of their natal sex, or that of their experienced gender? Findings from neuroimaging studies focusing on brain structure suggest that the brain phenotypes of trans women (MtF) and trans men (FtM) differ in various ways from control men and women with feminine, masculine, demasculinized and defeminized features. The brain phenotypes of people with feelings of gender incongruence may help us to figure out whether sex differentiation of the brain is atypical in these individuals, and shed light on gender identity development. Task-related imaging studies may show whether brain activation and task performance in transgender people is sex-atypical. Second, we review studies that evaluate the effects of cross-sex hormone treatment on the brain. This type of research provides knowledge on how changes in sex hormone levels may affect brain structure and function.

This research considers gender classification in surveillance environments, typically involving low-resolution images and a large amount of viewpoint variations and occlusions. Gender classification is inherently difficult due to the large intra-class variation and interclass correlation. We have developed a gender classification system, which is successfully evaluated on two novel datasets, which realistically consider the above conditions, typical for surveillance. The system reaches a mean accuracy of up to 90% and approaches our human baseline of 92.6%, proving a high-quality gender classification system. We also present an in-depth discussion of the fundamental differences between SVM and RF classifiers. We conclude that balancing the degree of randomization in any classifier is required for the highest classification accuracy. For our problem, an RF-SVM hybrid classifier exploiting the combination of HSV and LBP features results in the highest classification accuracy of 89.9 0.2%, while classification computation time is negligible compared to the detection time of pedestrians.

The purpose of this study was to evaluate the impact of donor age and donor-recipient gender matching on liver transplantation outcomes, focusing on differences between patients with and without hepatitis C virus (HCV) infection. This retrospective cohort study evaluated 622 liver transplantation recipients. HCV (n=164) and non-HCV (n=458) patients were subdivided by donor age (≤ 30, 31-50, and >50 years) and donor-recipient gender configurations. Five-year patient survival (PS) and graft survival (GS) were set as outcome measures. Five-year PS was 83.1% for HCV-positive and 81.6% for HCV-negative patients (p=0.614), with the corresponding GS rates of 81.2% and 79.3% (p=0.538), respectively. In HCV patients, transplantations from donors older than 50 years were associated with lower PS (p=0.035) and GS (p=0.006) than those from donors aged 31-50 years. This difference was not observed among non-HCV recipients (PS, p=0.994; GS, p=0.878). Regarding donor-recipient gender configurations, outcomes were similar in HCV (PS, p=0.751; GS, p=0.592) and non-HCV patients (PS, p=0.217; GS, p=0.249), except for a tendency toward lower PS for male-to-female transplantations than female-to-female transplantations in non-HCV patients (p=0.064). Outcomes of HCV patients were superior to those of non-HCV patients after transplantation from donors aged 31-50 years (PS, p=0.080; GS, p=0.026). Avoiding the transplantation of grafts from donors aged over 50 years to patients with HCV infection might improve the general outcomes of liver transplantation programs. There is no specific rationale for gender matching with respect to HCV status.

2015-01-01

The present study aimed to investigate gender differences in the emotional evaluation of 18 film clips divided into six categories: Erotic, Scenery, Neutral, Sadness, Compassion, and Fear. 41 female and 40 male students rated all clips for valence-pleasantness, arousal, level of elicited distress, anxiety, jittery feelings, excitation, and embarrassment. Analysis of positive films revealed higher levels of arousal, pleasantness, and excitation to the Scenery clips in both genders, but lower pleasantness and greater embarrassment in women compared to men to Erotic clips. Concerning unpleasant stimuli, unlike men, women reported more unpleasantness to the Compassion, Sadness, and Fear compared to the Neutral clips and rated them also as more arousing than did men. They further differentiated the films by perceiving greater arousal to Fear than to Compassion clips. Women rated the Sadness and Fear clips with greater Distress and Jittery feelings than men did. Correlation analysis between arousal and the other emotional scales revealed that, although men looked less aroused than women to all unpleasant clips, they also showed a larger variance in their emotional responses as indicated by the high number of correlations and their relatively greater extent, an outcome pointing to a masked larger sensitivity of part of male sample to emotional clips. We propose a new perspective in which gender difference in emotional responses can be better evidenced by means of film clips selected and clustered in more homogeneous categories, controlled for arousal levels, as well as evaluated through a number of emotion focused adjectives.

Uric acid is tightly linked to the metabolic syndrome (MetS) and among adults higher uric acid levels are associated with future risk for diabetes, cardiovascular disease, hypertension and renal disease. Evaluate the sensitivity of MetS to identify adolescents with elevated uric acid levels on a race/ethnicity and gender-specific basis. We evaluated 3296 male and female adolescents 12-19 y participating in the National Health and Nutrition Evaluation Survey 1999-06, comprised of 67.6% non-Hispanic whites, 15.1% non-Hispanic blacks, and 17.3% Hispanics. We used a definition of MetS modified for use in adolescents and evaluated the sensitivity of a diagnosis of MetS to identify individuals with uric acid elevations (approximately the 95th percentile of uric acid by gender among normal-weight adolescents). When used as a screening test to identify individuals with uric acid elevations MetS performed more poorly among females (18.0%) than among males (37.0%) (p<0.001). Among males, MetS exhibited a lower sensitivity among non-Hispanic blacks (17.8%) compared to Hispanics (45.9%) (p<0.01) and non-Hispanic whites (37.4%) (p<0.05). There were no race/ethnicity differences in detecting elevated uric acid levels among females (non-Hispanic-white 15.5%, non-Hispanic-black 19.4%, Hispanic 26.5%, p>0.05). Current criteria to diagnose MetS exhibit racial/ethnic and gender differences in the ability to identify adolescents with elevated uric acid levels, performing poorly among non-Hispanic-black males and among females. Given emerging data regarding the ability of uric acid elevations for predicting future disease, these data may have implications regarding the use of MetS as a marker of risk among all gender and racial/ethnic groups.

Females have a higher risk in terms of anterior cruciate ligament injuries during sports than males. Reasons for this fact may be different anatomy and muscle recruitment patterns leading to less protection for the cruciate- and collateral-ligaments. This in vitro study aims to evaluate gender differences in knee joint kinematics and muscle force during weight-bearing knee flexions. Thirty-four human knee specimens (17 females/17 males) were mounted on a dynamic knee simulator. Weight-bearing single-leg knee flexions were performed with different amounts of simulated body weight (BW). Gender-specific kinematics was measured with an ultrasonic motion capture system and different loading conditions were examined. Knee joint kinematics did not show significant differences regarding anteroposterior and medial-lateral movement as well as tibial varus-valgus and internal-external rotation. This applied to all simulated amounts of BW. Simulating 100 N BW in contrast to AF50 led to a significant higher quadriceps overall force in female knees from 45° to 85° of flexion in contrast to BW 50 N. In these female specimens, the quadriceps overall force was about 20 % higher than in male knees being constant in higher flexion angles. It is indicated by our results that in a squatting movement females compared with males produce higher muscle forces, suggesting an increased demand for muscular stabilization, whereas tibio-femoral kinematics was similar for both genders.

The aging population is a globally recognized challenge for the health care service. The growing number of older people will probably lead to increased demands for nurses working in elderly care. Clinical practice has been shown to have an impact on how student nurses perceive a particular field of nursing. To compare perceptions of the clinical learning environment in nursing homes among students considering a career in aged care or not, and to examine the difference in age, gender and previous working experience as health care assistants in elderly care between the two groups. This was a cross-sectional study using the Swedish version of the Clinical Learning Environment and Nurse Teacher evaluation scale. Consecutive sampling was performed over three semesters from September 2011 to December 2012. The survey was conducted with 183 student nurses. Mann-Whitney U-test was used to examine differences in relation to two groups namely student nurses who did or did not consider to work in elderly care. A chi-square test of independence was performed to examine the difference in age, gender and previous working experience between the two groups. The analysis leaned towards an overall positive evaluation of the clinical learning environment with more positive values for students considering a career. There were no significant differences between younger students (18-23) and older students (24-50) regarding willingness to work in elderly care or not. Neither was any significant difference displayed between students, based on gender nor for previous work experience. Age, gender and previous work experiences as health care assistants did not impact on students' willingness to work in elderly care. Future studies need to acknowledge the complexity of why student nurses choose a particular pathway in nursing by longitudinal studies following cohorts of students during the course of the nursing programme.

Clinical and hormonal features of polycystic ovary syndrome (PCOS), which may be present already in adolescence, can significantly influence the psychological development and wellbeing of a young woman.The aim of this pilot study was to determine social competence and gender roles in adolescent girls with PCOS compared to healthy peers, and to evaluate the relationship between psychological profile and clinical and hormonal components of PCOS. In 28 adolescent girls with PCOS, and 12 healthy regularly menstruating girls, clinical evaluation and hormonal profile were assessed and social competence inventory (SCI) and psychological gender inventory (PGI) tests were performed. There were no significant differences in all parts of SCI in absolute numbers or in sten scores between the study and the control group. Also in PGI, in both the feminine and masculine gender schemes, the differences between the groups were statistically insignificant. In the study group, DHEAS concentration correlated positively with self presentation score (r = 0.4, p = 0.03). There was also a significant negative correlation between testosterone level and SCI score (r = -0.5, p = 0.01) as well as assertiveness score (r = -0.5, p = 0.02). No significant correlations between SCI or PGI with BMI z-score or hirsutism score were found. Despite the existence of clinical and biochemical features that can influence sociopsychological condition, in adolescent girls with PCOS, social abilities and sex-typical behaviours do not seem to be disturbed.

Purpose To evaluate the prevalence of gonioscopically narrow angles in a Chinese-American population with glaucoma or glaucoma suspicion. Patients and Methods Charts from all Chinese-American patients seen in a comprehensive ophthalmology clinic in the Chinatown district of San Francisco in 2002 were reviewed. One eye from each patient with glaucoma or glaucoma suspicion that met inclusion criteria was included (n=108). Data was collected for gender, age, race (self-declared), refraction (spherical equivalent), intraocular pressure (IOP), gonioscopy and vertical cup-to-disk ratio (CDR). Results Sixty percent (n=65) of Chinese-American eyes with glaucoma or glaucoma suspicion had gonioscopically narrow angles (Shaffer grade ≤2 in three or more quadrants). Those with narrow angles were significantly older (P=0.004) than their open angle counterparts, but the two groups did not differ in terms of gender, refraction, IOP or CDR (all, P≥0.071). In a multivariate model including age, gender and refraction as predictors of angle grade (open or narrow), only age was a significant predictor of angle grade (P=0.004). Conclusions A large proportion of Chinese-Americans in our study population with glaucoma or glaucoma suspicion had gonioscopically narrow angles. In multivariate analysis, patients with narrow angles were older than those with open angles but did not differ from them in terms of gender or refraction. Continued evaluation of angle closure glaucoma risk among Chinese-Americans is needed. PMID:19826385

Previous work suggests women might possess an advantage over men in experiencing and benefiting from gratitude. We examined whether women perceive and react to gratitude differently than men. In Study 1, women, compared with men, evaluated gratitude expression to be less complex, uncertain, conflicting, and more interesting and exciting. In Study 2, college students and older adults described and evaluated a recent episode when they received a gift. Women, compared with men, reported less burden and obligation and greater gratitude. Upon gift receipt, older men reported the least positive affect when their benefactors were men. In Studies 2 and 3, women endorsed higher trait gratitude compared with men. In Study 3, over 3 months, women with greater gratitude were more likely to satisfy needs to belong and feel autonomous; gratitude had the opposite effect in men. The willingness to openly express emotions partially mediated gender differences, and effects could not be attributed to global trait affect. Results demonstrated that men were less likely to feel and express gratitude, made more critical evaluations of gratitude, and derived fewer benefits. Implications for the study and therapeutic enhancement of gratitude are discussed.

Saliva is essential to maintain and preserve oral health. Previous studies of primarily white populations demonstrated that salivary gland flow rates are age-stable in healthy adults, but there are little data on African Americans of different ages. The purpose of this study was to determine if there is a relationship between age, gender, and race in unstimulated and stimulated parotid and submandibular salivary gland flow rates and to evaluate subjective responses to questions regarding salivary dysfunction. Sixty generally healthy, middle socioeconomic class African Americans and whites between the ages of 20 to 40 and 60 to 80 years were evaluated. The results indicate, in general, that objective and subjective measurements of major salivary gland flow rates are independent of age, gender, and race. Further studies are required using larger populations. These results suggest that signs and symptoms of dry mouth in the elderly regardless of race or gender should not be considered a normal sequela of aging. PMID:7897685

Contact dermatitis is more frequent among women for anatomical reasons and for extraprofessional exposure to irritants and detergents during homeworks. In addition sensitisation to contact haptens is different in sexes. The aim of our work was to evaluate the association between patch test skin sensitizations and professional exposure to metals analyzing data for gender. Of the 15.217 patients patch tested for dermatitis, 678 were metalworkers. The statistical analysis revealed a significant association between dermatitis and sensitisation to nickel in professional exposed women (OR = 1.68; LC50% 1.11-6.50) while metal sensitisation (Cr.Ni and Co) was not relevant in men: for them a significant association between dermatitis and sensitisation was found to quaternium (OR = 3.91; LC95% 1.18-12.9), to mercaptobenzothiazole (OR = 2.69; LC50% 1.11-6.50) and to ethylendiamine dichloride (OR = 2.53; LC95% 1-6.41). The authors stress the need to evaluate patch test sensitisation considering gender effects.

Women often complain that their partners are not romantic enough. This raises the question: how romance is recognized and evaluated in a love relationship? However, there has been essentially no empirical research bearing on this issue. The present set of studies examined possible gender differences in perceptions of romance and the associated neural mechanisms in Chinese college students. In Study 1, 303 participants (198 women, 105 men) were administrated a questionnaire consisting of 60 sentences and required to rate the romance level of each sentence. Results showed higher rating scores in males than females for low romance items, but not for high or medium romance items. In Study 2, 69 participants (37 women, 32 men) were recruited to judge the degree of romance in sentences presented on a computer screen one by one. Compared with females, males again showed higher scores and responded more slowly only to low romance items. In Study 3, 36 participants (18 women, 18 men) currently in love with someone were scanned with functional MRI while they did the romance judgment task from Study 2. Compared with females, greater brain activation was found for males in the frontal lobe, precentral gyrus, precuneus and parahippocampal gyrus for low romance items. The results provide the first piece of evidence for gender differences in romance perception, suggesting enhanced cognitive processing in males when evaluating the degree of romance in romantic scenes.

Background. Multiple sclerosis (MS) rates in Latin America are increasing, and caregivers there experience reduced mental and physical health. Based on rigid gender roles in Latin America, women more often assume caregiving duties, yet the differential impact on women of these duties is unknown. Methods. This study examined gender differences in mental health (Patient Health Questionnaire-9, Satisfaction with Life Scale, Rosenberg Self-Esteem Scale, State-Trait Anxiety Inventory, and Zarit Burden Inventory), health-related quality of life (HRQOL; Short Form-36), and social support (Interpersonal Support Evaluation List-12) in 81 (66.7% women) Mexican MS caregivers. Results. As compared to men caregivers, women had lower mental health (p = 0.006), HRQOL (p < 0.001), and social support (p < 0.001). This was partially explained by women caregivers providing care for nearly twice as many hours/week as men (79.28 versus 48.48, p = 0.018) and for nearly three times as many months (66.31 versus 24.30, p = 0.002). Conclusions. Because gender roles in Latin America influence women to assume more substantial caregiving duties, MS caregiver interventions in Latin America—particularly for women caregivers—should address the influence of gender-role conformity on care and psychosocial functioning.

The acute phase of stroke is accompanied by functional changes in the activity and interplay of both hemispheres. In healthy subjects, gender is known to impact the functional brain organization. We investigated whether gender influences also acute stroke functional changes. In thirty-five ischemic stroke patients, we evaluated the excitability of the affected (AH) and unaffected hemisphere (UH) by measuring resting and active motor threshold (AMT) and motor-evoked potential amplitude under baseline conditions and after intermittent theta burst stimulation (iTBS) of AH. We also computed an index of the excitability balance between the hemispheres, laterality indexes (LI), to evidence hemispheric asymmetry. AMT differed significantly between AH and UH only in the male group (p = 0.004), not in females (p > 0.200), and both LIAMT and LIRMT were significantly higher in males than in females (respectively p = 0.033 and p = 0.042). LTP-like activity induced by iTBS in AH was more frequent in females. Gender influences the functional excitability changes that take place after human stroke and the level of LTP that can be induced by repetitive stimulation. This knowledge is of high value in the attempt of individualizing to different genders any non-invasive stimulation strategy designed to foster stroke recovery. PMID:26858590

Compared with traditional rehabilitation, gardening has been viewed as a more occupation-based intervention to help patients improve functional performance. However, there is still a need for evidence-based research into what factors interact to create the beneficial effects of gardening for people who have sustained a cerebral vascular accident (CVA). To explore how plant, gender, and the time after stroke onset influenced improvements in the quality of life of patients in a gardening program. One treatment of tending short-term plants, and another treatment of tending long-term plants were compared. Quality of life improvement was evaluated according to three factors: plant, gender, and the time after stroke onset. The data were analyzed with 2k replicated factorial designs. The 2k factorial design with replication indicated significant effects on both the social role and the family role. For the social role, the interaction of plant and gender difference was significant. For the family role, the significant effects were found on interaction of plant with both gender and the time after stroke onset. Tending plants with different life cycles has varied effects on the quality of life of people who have sustained a CVA. Factors related to gender and the time after stroke onset influenced role competency in this sample.

This meta-analysis surveyed 177 usable sources that reported data on gender differences on 21 different measures of sexual attitudes and behaviors. The largest gender difference was in incidence of masturbation: Men had the greater incidence (d = .96). There was also a large gender difference in attitudes toward casual sex: Males had considerably more permissive attitudes (d = .81). There were no gender differences in attitudes toward homosexuality or in sexual satisfaction. Most other gender differences were in the small-to-moderate range. Gender differences narrowed from the 1960s to the 1980s for many variables. Chodorow's neoanalytic theory, sociobiology, social learning theory, social role theory, and script theory are discussed in relation to these findings.

Many studies carried out on treatment-seeking problem gamblers (PG) have reported high levels of comorbid substance use disorders, and mental and physical health problems. Nevertheless, general population studies are still sparse, most of them have been carried out in the United States or Canada, and gender differences have not always been considered. Thus, the aim of this study was to describe the type of games, and psychological and physical correlates in male and female PG in a nationally representative French sample. The total sample studied involved 25,647 subjects aged 15-85 years, including 333 PG and 25,314 non-problem gamblers (NPG). Data were extracted from a large survey of a representative sample of the French general population. They were evaluated for sociodemographic variables, gambling behavior, type of gambling activity, substance use, psychological distress, body mass index, chronic disease, and lack of sleep. Overall, there were significant differences between PG and NPG in gender, age, education, employment and marital status, substance use disorders (alcohol, tobacco, cannabis, cocaine and heroin), psychological distress, obesity, lack of sleep and type of gambling activity. Although male and female PG had different profiles, the gambling type, especially strategic games, appeared as an important variable in the relationship between gender and problem gambling. This research underlines the importance of considering gender differences and gambling type in the study of gambling disorders. Identifying specific factors in the relationship between gender, gambling type and gambling problems may help improve clinical interventions and health promotion strategies.

A significant number of potential kidney transplant candidates do not complete the required medical evaluation after referral to a transplant program. Factors associated with rate of completion of the renal transplant evaluation were analyzed using a retrospective chart review of patients first seen between October 1, 2009, and September 30, 2010 (n=256). The primary endpoint was completion in 12 months. Independent variables included socioeconomic, demographic, and medical factors. Mean age was 50.7 years; 49.6% were black, 28.5% Hispanic, and 21.9% white and other; 26.3% did not require dialysis. During follow-up, 23.4% did not complete the evaluation. Multivariable analysis indicated that slower rates of completion were associated with needing a greater number of medical tests (compared to 0-2: 3-5 tests, hazard ratio [HR]=0.65, P=0.02; ≥ 6 tests, HR=0.47, P=0.0005) and requiring more than one hospitalization (compared to none: HR=0.37, P=0.0008). A significant interaction between race or ethnicity and gender on completion was found: compared to black men, Hispanic men (HR=2.75, P<0.0001), Hispanic women (HR=1.96, P=0.006), and white men (HR=1.99, P=0.005) showed a more rapid completion. In comparison, black and white women (HR=1.38, P=0.16; HR=0.94, P=0.83, respectively) were not significantly different from black men in rates of completion. Differences by race or ethnicity and gender were not confounded by socioeconomic variables or social support. To lessen barriers and facilitate renal transplantation, black men and women, white women, and patients needing multiple medical tests and requiring several hospitalizations may benefit from additional assistance during the medical evaluation process.

Esophageal achalasia is a relatively rare disease that occurs usually in middle-aged patients. The laparoscopic Heller-Dor (LHD) procedure is the gold-standard surgical treatment for esophageal achalasia. There are many studies on the pathology and surgical outcome of esophageal achalasia from various perspectives, but there are no studies on gender differences in both the pathology and surgical outcome. This study aimed to evaluate gender differences in the surgical outcome with the LHD procedure and in the pathology of esophageal achalasia patients. The study included 474 LHD-treated patients who were postoperatively followed up for 6 months or more. The patients were divided into 2 groups by gender, to compare the preoperative pathology, surgical outcome, symptom scores before and after LHD, symptom score improvement frequency, and patient satisfaction with the surgery. The study population consisted of 248 male and 226 female, having a mean age of 45.1 years. There were no gender differences in the preoperative pathology, but a significantly lower BMI (p < 0.0001) and a smaller esophageal dilation (p = 0.0061) were observed in the female group. The frequency and severity of chest pain before the surgery were significantly higher in the female group (p = 0.0117 and p = 0.0103, respectively), and the improvement in both the frequency and severity of chest pain was significantly higher in the female group (p = 0.0005 and p = 0.003, respectively). No differences were identified in the surgical outcomes and postoperative course. The patient satisfaction with the surgery was high in both groups and comparable (p = 0.6863). The female patients with esophageal achalasia were characterized by low BMI, less esophageal dilation, and increased frequency and severity of chest pain. LHD improved the chest pain in the female patients, whereas the surgical outcome and satisfaction with the surgery were excellent regardless of gender.

Although sporadic male predominance in hiccup patients has been reported, the association between gender differences and triggering factors has rarely been evaluated in patients with hiccups. The aim of this study was to investigate whether gender differences exist in hiccup patients by analyzing all previously published hiccup literature containing gender and etiology information. Published literature on this topic was identified using a standardized search strategy in the PubMed, SCOPUS, and CINAHL electronic databases. The literature search included studies published from January 1990 to December 2013. Searches were limited to English-language publications. Of 476 identified studies, 318 studies were eligible including eight case-control studies that contained nonhiccup control groups. Triggering factors for hiccups were categorized into two types: central nervous system (CNS) and non-CNS causes. Odds ratios (ORs) were calculated for the eight case-control studies and event rates for the other studies by meta-analysis. In addition, gender differences and mean ages were analyzed for the case studies. Pooled OR was 2.42 (95% confidence interval [CI] 1.40-4.17) with inclination for male predominance. Subgroup analysis by cause showed clear male predominance in the non-CNS type with OR of 11.72 (95% CI 3.16-43.50), whereas indistinct in the CNS type with OR of 1.74 (95% CI 0.95-3.16). Of the remaining 310 studies with 864 patients, previous findings were consistent. Male predominance was consistent in non-CNS (85.1%, 95% CI 78.2-90.2) and unknown origin (82.2%, 95% CI 75.8-87.2) patients, whereas mitigating the sex discrepancy in those with CNS origin (65.8%, 95% CI 53.1-76.5). We demonstrated male predominance in hiccup patients. This gender difference for hiccups was more pronounced in patients with non-CNS causes, whereas indistinct in patients with CNS causes.

The role of acetylcholinesterase (AChE) in the termination of the cholinergic response through acetylcholine (ACh) hydrolysis and the involvement of plasma butyrylcholinesterase (BuChE), mainly of hepatic origin, in the metabolism of xenobiotics with ester bonds is well known. Besides, BuChE has a crucial role in ACh hydrolysis, especially when selective anticholinesterases inhibit AChE. Herein, we analyzed the gender-related differences and the circadian changes of rat plasma cholinesterases. Plasma and liver cholinesterase activities were evaluated in control or 2-30-day castrated adult male and female rats. Plasma and liver AChE activities did not differ between genders and were not influenced by sex hormone deprivation. BuChE plasma activity was 7 times greater in female, reflecting gender differences in liver enzyme expression. Castration increased liver and plasma BuChE activity in male, while reduced it in female, abolishing gender differences in enzyme activity. Interestingly, female AChE and BuChE plasma activities varied throughout the day, reaching values 27% and 42% lower, respectively, between 2 p.m. and 6 p.m. when compared to the morning peaks at 8 a.m. Castration attenuated daily female BuChE oscillation. On the other hand, male plasma enzymes remained constant throughout the day. In summary, our results show that liver and plasma BuChE, but not AChE, expression is influenced by sex hormones, leading to high levels of blood BuChE in females. The fluctuation of female plasma BuChE during the day should be taken into account to adjust the bioavailability and the therapeutic effects of cholinesterase inhibitors used in cholinergic-based conditions such Alzheimer's disease.

Background Farmwork is one of the most hazardous occupations for men and women. Research suggests sex/gender shapes hazardous workplace exposures and outcomes for farmworkers. This paper reviews the occupational health literature on farmworkers, assessing how gender is treated and interpreted in exposure-outcome studies. Methods The paper evaluates peer-reviewed articles on men and women farmworkers' health published between 2000 and 2012 in PubMed or SCOPUS. Articles were identified and analyzed for approaches toward sampling, data analysis, and use of exposure indicators in relation to sex/gender. Results 18% of articles reported on and interpreted sex/gender differences in health outcomes and exposures. Sex/gender dynamics often shaped health outcomes, yet adequate data was not collected on established sex/gender risk factors relating to study outcomes. Conclusion Research can better incorporate sex/gender analysis into design, analytical and interpretive approaches to better explore its mediation of health outcomes in light of emerging calls to mainstream gender research.

Face aftereffects are proving to be an effective means of examining the properties of face-specific processes in the human visual system. We examined the role of gender in the neural representation of faces using a contrast-based adaptation method. If faces of different genders share the same representational face space, then adaptation to a face of one gender should affect both same- and different-gender faces. Further, if these aftereffects differ in magnitude, this may indicate distinct gender-related factors in the organization of this face space. To control for a potential confound between physical similarity and gender, we used a Bayesian ideal observer and human discrimination data to construct a stimulus set in which pairs of different-gender faces were equally dissimilar as same-gender pairs. We found that the recognition of both same-gender and different-gender faces was suppressed following a brief exposure of 100 ms. Moreover, recognition was more suppressed for test faces of a different-gender than those of the same-gender as the adaptor, despite the equivalence in physical and psychophysical similarity. Our results suggest that male and female faces likely occupy the same face space, allowing transfer of aftereffects between the genders, but that there are special properties that emerge along gender-defining dimensions of this space.

Although numerous investigations of overt aggressive and antisocial trajectories have been undertaken, there is a dearth of literature examining gender differences and similarities in trajectory patterns and their correlates. To address these gaps, we investigated gender differences in the prevalence rates, predictive validity during transition to adulthood, childhood risk factors, and adolescent correlates of different trajectories of teacher-reported overt aggression (i.e., fights, argues, gets in trouble) among 220 participants (116 girls and 104 boys) evaluated annually from grade 4 to grade 12. Four patterns of trajectories were identified: low, increasing (i.e., adolescent-onset), decreasing (i.e., childhood-limited), and high (i.e., childhood-onset). majority large proportion of youth, particularly girls, displayed low levels of aggression over time. A small proportion followed the childhood-onset trajectory. Across gender, the childhood-onset trajectory was associated with the highest rates of maladjustment during the transition to adulthood, the highest number of childhood risk factors, and multiple problems during adolescence. The adolescent-onset trajectory was associated with few childhood risk factors, but with high levels of independent status during adolescence. In contrast, the childhood-limited trajectory was associated with several childhood risk factors, but high levels of parental monitoring and school engagement during adolescence. Romantic involvement differentiated the adolescent-onset and childhood-limited trajectories among girls. PMID:21748751

It remains controversial whether the diagnostic accuracy of single-photon emission computed tomography myocardial perfusion imaging (SPECT MPI) is different in men as compared to women. We performed a meta-analysis to investigate gender differences of SPECT MPI for the diagnosis of CAD (≥50% stenosis). Two investigators independently performed a systematic review of the MEDLINE and EMBASE databases from inception through January 2012 for English-language studies determining the diagnostic accuracy of SPECT MPI. We included prospective studies that compared SPECT MPI with conventional coronary angiography which provided sufficient data to calculate gender-specific true and false positives and negatives. Data from studies evaluating <20 patients of one gender were excluded. Bivariate meta-analysis was used to create summary receiver operating curves. Twenty-six studies met inclusion criteria, representing 1,148 women and 1,142 men. Bivariate meta-analysis yielded a mean sensitivity and specificity of 84.2% (95% confidence interval [CI] 78.7%-88.6%) and 78.7% (CI 70.0%-85.3%) for SPECT MPI in women and 89.1% (CI 84.0%-92.7%) and 71.2% (CI 60.8%-79.8%) for SPECT MPI in men. There was no significant difference in the sensitivity (P = .15) or specificity (P = .23) between male and female subjects. In a bivariate meta-analysis of the available literature, the diagnostic accuracy of SPECT MPI is similar for both men and women.

Access to dialysis treatment and the types of treatments employed in Australia differs by Indigenous status. We examined whether dialysis treatment utilisation in Indigenous and non-Indigenous Australians also differs by gender. Using registry data we evaluated 21,832 incident patients (aged ≥18 years) commencing dialysis, 2001-2013. Incidence rates were calculated and multivariate regression modelling used to examine differences in dialysis treatment (modality, location and vascular access creation) by race and gender. Dialysis incidence was consistently higher in Indigenous women compared to all other groups. Compared to Indigenous women, both non-Indigenous women and men were more likely to receive peritoneal dialysis as their initial treatment (non-Indigenous women RR=1.91, 95%CI 1.55-2.35; non-Indigenous men RR=1.73, 1.40-2.14) and were more likely to commence initial treatment at home (non-Indigenous women RR=2.07, 1.66-2.59; non-Indigenous men RR=1.95, 1.56-2.45). All groups were significantly more likely than Indigenous women to receive their final treatment at home. Contemporary dialysis treatment in Australia continues to benefit the dominant non-Indigenous population over the Indigenous population, with non-Indigenous men being particularly advantaged. Implications for Public Health: Treatment guidelines that incorporate a recognition of gender-based preferences and dialysis treatment options specific to Indigenous Australians may assist in addressing this disparity. © 2016 The Authors.

Background: Implicit gender bias may result in lower wages for women, fewer leadership positions, and lower perceived competence. Understanding public and patient gender preferences for plastic surgeons may enable opportunities to address public perceptions. This investigation evaluates public preferences for a plastic surgeon’s gender or demeanor. Methods: Members of the Amazon Mechanical Turk crowdsourcing platform read 1 of the 8 randomly assigned scenarios describing a hypothetical situation requiring a plastic surgeon to operate on their mother. The scenarios differed only by surgeon gender, surgeon demeanor (“agentic,” traditionally more masculine versus “communal,” traditionally more feminine), or type of surgery. Using a Likert scale, respondents indicated their agreement with 7 statements on surgeon competence, skills, leadership qualities, likeability, respect, trustworthiness, and, ultimately, preference as a surgeon. Independent t tests were used to compare scores. Lower scores indicated a more negative response. Results: Overall, 341 responses were received: 55.7% were male and 45.5% white. There were no significant differences in any of the 7 characteristics assessed when examining by surgeon gender, only. However, female surgeons with a communal demeanor were perceived as less competent (4.32 versus 4.51, P = 0.018) and less skilled (4.36 versus 4.56, P = 0.019) than agentic female surgeons. Male respondents rated female surgeons lower than male surgeons in terms of competence (P = 0.018), skills (P = 0.034), likeability (P = 0.042), and preferred choice as a surgeon (P = 0.033). Conclusions: Women plastic surgeons’ demeanor and respondent gender affected perception of certain characteristics. Women plastic surgeons may consider ways to engage with the public to address possible gender role stereotypes. PMID:29876174

While studies have documented gender differences by histologic type among lung cancer patients, the effect of these differences on the health-related quality of life (HRQoL) of post-lobectomy lungcancer patients and related factors remain uncertain. This study examines gender-specific HRQoL and related factors in post-lobectomy lung-cancer patients. A cross-sectional study design was applied. A convenience sample of 231 post-lobectomy lungcancer patients was recruited from the thoracic surgery outpatient departments of two teaching hospitals in Taipei, Taiwan from March to December 2012. Patients performed a spirometry test and completed instruments that included a Beck Depression Inventory-II, an Interpersonal Support Evaluation List, and the symptom and function scales of the Quality of Life Questionnaire. Data analysis used descriptive statistics, including mean and standard deviations, frequency, and percentage values. Independent-sample Student's t-tests and multivariate analyses were used for comparative purposes. This study confirmed a significant gender effect on HRQoL and HRQoL-related factors such as marital status, religious affiliation, smoking status, histologic type, symptoms, pulmonary function, depression, and family support. Moreover, multivariate analysis found gender to be a significant determinant of the HRQoL aspects of physical functioning, emotional functioning, and cognitive functioning. Finally, results indicated that factors other than gender were also significant determinants of HRQoL. Gender impacts the HRQoL and related factors of postoperative lung-cancer patients. Therefore, gender should be considered in assessing and addressing the individual care needs of these patients in order to attain optimal treatment outcomes. Copyright © 2014 Elsevier Ltd.

Gender, risk assessment, and political ambition.

PubMed

Sweet-Cushman, Jennie

2016-01-01

In the United States, women have long held the right to vote and can participate fully in the political process, and yet they are underrepresented at all levels of elected office. Worldwide, men's dominance in the realm of politics has also been the norm. To date, scholars have focused on supply-side and demand-side explanations of women's underrepresentation but differences in how men and women assess electoral risk (the risk involved in seeking political office) are not fully explained. To fill this gap, I explore how evolutionary theory offers insights into gendered differences in political ambition and the evaluation of electoral risk. Using the framework of life-history theory, I hypothesize that both cognitive and environmental factors in human evolution, particularly as they relate to sexual selection and social roles, have shaped the psychology of ambition in gendered ways affecting contemporary politics. Cognitive risk-assessment mechanisms evolving in the hominid line came to be expressed differently in females and males, in women and men. These gendered expressions plausibly reflect differentiable environmental pressures in the past and may help explain behaviors in and barriers to women's electoral political activity in the present. If so, then the success of efforts to increase such activity - or, regressively, to suppress it - may be better understood.

Various measures of auditory function are reported to be superior in females as compared to males, in African American compared to Caucasian individuals, and in right compared to left ears. We re-examined the influence of these subject variables on hearing thresholds and otoacoustic emissions (OAEs) in a sample of 887 human participants between 10 and 68 years of age. Even though the variables of interest here have been examined before, previous attempts have largely been limited to frequencies up to 8 kHz. We used state-of-the-art signal delivery and recording techniques that compensated for individual differences in ear canal acoustics, allowing us to measure hearing thresholds and OAEs up to 20 kHz. The use of these modern calibration and recording techniques provided the motivation for re-examining these commonly studied variables. While controlling for age, noise exposure history, and general health history, we attempted to isolate the effects of gender, race, and ear (left versus right) on hearing thresholds and OAEs. Our results challenge the notion of a right ear advantage and question the existence of a significant gender and race differences in both hearing thresholds and OAE levels. These results suggest that ear canal anatomy and acoustics should be important considerations when evaluating the influence of gender, race, and ear on peripheral auditory function.

Although research has long documented the relevance of gender for health, studies that simultaneously incorporate the relevance of disparate sexual orientation groups are sparse. We address these shortcomings by applying an intersectional perspective to evaluate how sexual orientation and gender intersect to pattern self-rated health status among U.S. adults. Our project aggregated probability samples from the Behavioral Risk Factor Surveillance System (BRFSS) across seven U.S. states between 2005 and 2010, resulting in an analytic sample of 10,128 sexual minority (gay, lesbian, and bisexual) and 405,145 heterosexual adults. Logistic regression models and corresponding predicted probabilities examined how poor self-rated health differed across sexual orientation-by-gender groups, before and after adjustment for established health risk factors. Results reveal distinct patterns among sexual minorities. Initially, bisexual men and women reported the highest--and gay and lesbian adults reported the lowest--rates of poor self-rated health, with heterosexuals in between. Distinct socioeconomic status profiles accounted for large portions of these differences. Furthermore, in baseline and fully adjusted regression models, only among heterosexuals did women report significantly different health from men. Importantly, the findings highlight elevated rates of poor health experienced by bisexual men and women, which are partially attributable to their heightened economic, behavioral, and social disadvantages relative to other groups.

Mental rotation ability has an important role in human navigation and, together with other cognitive abilities such as processing speed, working memory, and attention, is crucial for aircraft navigation. In the human performance literature, mental rotation tasks have consistently yielded reports of gender differences favoring men. The aim of this study was to compare the gender difference measured in a specialized population of aviators vs. a matched population of nonpilots. : Studied were 41 pilots (20 men and 21 women) and 38 nonpilots (20 men and 18 women) matched for age and education. Pilots were stratified for flying hours. Participants performed a mental rotation task (MRT) in which accuracy and response time were recorded, and also completed sense-of-direction (SOD) and spatial cognitive styles self-evaluation scales. Men had significantly smaller response time in the MRT (men 279.6 +/- 147.0 s, women 401.6 +/- 361.3) and greater SOD (men's score 49.1 +/- 8.6, women's score 46.6 +/- 7.8), but these differences were absent among pilots. A positive relationship was also identified between pilots' response times and their flight hours. These data suggest that the effect of gender on the speed of cognitive spatial processing is absent in a population with aviation experience. Gender effects may be associated with a low spatial cognitive style, whereas in groups such as aviators, who are expected to have high spatial cognitive style, other factors such as experience may come into play.

The purpose of this study was to examine biological and behavioral explanations for gender differences in leukocyte telomere length (LTL), a biomarker of cell aging that has been hypothesized to contribute to women’s greater longevity. Data are from a subsample (n = 851) of the Multi-Ethnic Study of Atherosclerosis, a population-based study of women and men aged 45 to 84. Mediation models were used to examine study hypotheses. We found that women had longer LTL than men, but the gender difference was smaller at older ages. Gender differences in smoking and processed meat consumption partially mediated gender differences in telomere length, whereas gender differences in estradiol, total testosterone, oxidative stress, and body mass index did not. Neither behavioral nor biological factors explained why the gender difference in LTL was smaller at older ages. Longitudinal studies are needed to assess gender differences in the rate of change in LTL over time; to identify the biological, behavioral, and psychosocial factors that contribute to these differences throughout the life course; and to determine whether gender differences in LTL explain the gender gap in longevity.

The purpose of this study was to evaluate the correlation between chronological age and the degree of third molar mineralization by Demirjian's developmental stages (Demirjian et al., 1973) using panoramic radiography. From a total of 11.396 digital panoramic radiographs of patients from three oral radiology private clinics from the northeast region of Brazil, obtained from January to June 2009, 2097 radiographic images from patients aged between 6 and 22 years were selected. The images were analyzed individually by two obsevers using a 21-inch computer screen and Windows Picture and Fax Viewer. Reliability was achieved by intra- and interobserver evaluation, using the Kappa test. Chronological age, calcification stage, gender and third molar were interrelated using a multiple linear regression model, considering age as a response variable. There was reliability with Demirjian et al.'s developmental stage assesment, displaying a significant relationship between mineralization stages and patients' age (P<0.05). There was no significant difference between the average age and the calcification stage taking gender and localization of the third molar into consideration. It is possible to estimate chronological age based on Demirjian's stage of a third molar, regardless of gender and location. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Background This study was carried out to quantify and compare the quantitative image quality of coronary computed tomography angiography (CCTA) between genders as well as between different tube voltages scan protocols. Methods Fifty-five cases of CCTA were collected retrospectively and all images including reformatted axial images at systolic and diastolic phases as well as images with curved multi planar reformation (cMPR) were obtained. Quantitative image quality including signal intensity, image noise, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of right coronary artery (RCA), left anterior descending artery (LAD), left circumflex artery (LCx) and left main artery (LM) were quantified using Analyze 12.0 software. Results Six hundred and fifty-seven coronary arteries were evaluated. There were no significant differences in any quantitative image quality parameters between genders. 100 kilovoltage peak (kVp) scanning protocol produced images with significantly higher signal intensity compared to 120 kVp scanning protocol (P<0.001) in all coronary arteries in all types of images. Higher SNR was also observed in 100 kVp scan protocol in all coronary arteries except in LCx where 120 kVp showed better SNR than 100 kVp. Conclusions There were no significant differences in image quality of CCTA between genders and different tube voltages. Lower tube voltage (100 kVp) scanning protocol is recommended in clinical practice to reduce the radiation dose to patient. PMID:28275559
Genetic and Environmental Influences on Parent-Child Conflict and Child Depression Through Late Adolescence.

Few studies have investigated potential gender differences in the genetic and environmental influences on the prospective associations between parent-child conflict and later depression, a notable gap given substantial gender differences in rates of depression and suggestive evidence of differences in the etiology of depression among females and males. To fill this gap, we evaluated whether the prospective relationship between parent-child conflict and major depressive disorder symptoms varied as a function of parent-child gender composition. A combined twin and adoption sample was used (53% female; 85% European ancestry), containing 1,627 adolescent sibling pairs (789 monozygotic twin pairs, 594 dizygotic/full-biological pairs, 244 genetically unrelated pairs) with assessments at two time points in adolescence (approximate ages 15 and 18). Prospective associations between parent-child conflict and subsequent adolescent depression were explained predominately through common genetic influences for mother-daughter and mother-son pairs but less so for father-daughter and father-son pairs. Results support the notion that processes of gene-environment correlation involved in the prospective associations between parent-child conflict, and later adolescent depression appear to be less relevant to father-child relationships in comparison to mother-child relationships. Notably, results did not show that parent-child conflict was more relevant to the etiology of major depressive disorder (MDD) for girls than boys; gender differences in depression do not appear to be due to differences in the associations between parent-child conflict and child depression.

We examined the application and review materials of three calls (n=2,823) of a prestigious grant for personal research funding in a national full population of early career scientists awarded by the Netherlands Organization for Scientific Research (NWO). Results showed evidence of gender bias in application evaluations and success rates, as well as in language use in instructions and evaluation sheets. Male applicants received significantly more competitive "quality of researcher" evaluations (but not "quality of proposal" evaluations) and had significantly higher application success rates than female applicants. Gender disparities were most prevalent in scientific disciplines with the highest number of applications and with equal gender distribution among the applicants (i.e., life sciences and social sciences). Moreover, content analyses of the instructional and evaluation materials revealed the use of gendered language favoring male applicants. Overall, our data reveal a 4% "loss" of women during the grant review procedure, and illustrate the perpetuation of the funding gap, which contributes to the underrepresentation of women in academia.

We examined the application and review materials of three calls (n = 2,823) of a prestigious grant for personal research funding in a national full population of early career scientists awarded by the Netherlands Organization for Scientific Research (NWO). Results showed evidence of gender bias in application evaluations and success rates, as well as in language use in instructions and evaluation sheets. Male applicants received significantly more competitive “quality of researcher” evaluations (but not “quality of proposal” evaluations) and had significantly higher application success rates than female applicants. Gender disparities were most prevalent in scientific disciplines with the highest number of applications and with equal gender distribution among the applicants (i.e., life sciences and social sciences). Moreover, content analyses of the instructional and evaluation materials revealed the use of gendered language favoring male applicants. Overall, our data reveal a 4% “loss” of women during the grant review procedure, and illustrate the perpetuation of the funding gap, which contributes to the underrepresentation of women in academia.

Transgender (trans) and gender-nonconforming adults have reported reduced access to health care because of discrimination and lack of knowledgeable care. This study aimed to contribute to the nascent cancer prevention literature among trans and gender-nonconforming individuals by ascertaining rates of breast, cervical, prostate, and colorectal cancer screening behaviors by gender identity. Publicly available de-identified data from the 2014-2016 Behavioral Risk Factor Surveillance System surveys were utilized to evaluate rates of cancer screenings by gender identity, while controlling for healthcare access, sociodemographics, and survey year. Analyses were conducted in 2017. Weighted chi-square tests identified significant differences in the proportion of cancer screening behaviors by gender identity among lifetime colorectal cancer screenings, Pap tests, prostate-specific antigen tests, discussing prostate-specific antigen test advantages/disadvantages with their healthcare provider, and up-to-date colorectal cancer screenings and Pap tests (p<0.036). Weighted logistic regressions found that although some differences based on gender identity were fully explained by covariates, trans women had reduced odds of having up-to-date colorectal cancer screenings compared to cisgender (cis) men (AOR=0.20) and cis women (AOR=0.24), whereas trans men were more likely to ever receive a sigmoidoscopy/colonoscopy as compared to cis men (AOR=2.76) and cis women (AOR=2.65). Trans women were more likely than cis men to have up-to-date prostate-specific antigen tests (AOR=3.19). Finally, trans men and gender-nonconforming individuals had reduced odds of lifetime Pap tests versus cis women (AOR=0.14 and 0.08, respectively), and gender-nonconforming individuals had lower odds of discussing prostate-specific antigen tests than cis men (AOR=0.09; all p<0.05). The findings indicate that gender identity disparities in cancer screenings persist beyond known sociodemographic and healthcare factors. It is critical that gender identity questions are included in cancer and other health-related surveillance systems to create knowledge to better inform healthcare practitioners and policymakers of appropriate screenings for trans and gender-nonconforming individuals.

Why is high-risk drinking more prevalent among men than women? evidence from South Korea

PubMed Central

2012-01-01

Background It is important to identify and quantify the factors that affect gender differences in high-risk drinking (HRD), from both an academic and a policy perspective. However, little is currently known about them. This study examines these factors and estimates the percentage contribution each makes to gender differences in HRD. Methods This study analyzed information on 23,587 adults obtained from the Korea National Health and Nutrition Surveys of 1998, 2001, and 2005. It found that the prevalence of HRD was about 5 times higher among men (0.37) than women (0.08). Using a decomposition approach extended from the Oaxaca-Blinder method, we decomposed the gender difference in HRD to an "overall composition effect" (contributions due to gender differences in the distribution of observed socio-economic characteristics), and an "overall HRD-tendency effect" (contributions due to gender differences in tendencies in HRD for individuals who share socio-economic characteristics). Results The HRD-tendency effect accounted for 96% of the gender difference in HRD in South Korea, whereas gender differences in observed socio-economic characteristics explained just 4% of the difference. Notably, the gender-specific HRD-tendency effect accounts for 90% of the gender difference in HRD. Conclusion We came to a finding that gender-specific HRD tendency is the greatest contributor to gender differences in HRD. Therefore, to effective reduce HRD, it will be necessary to understand gender differences in socioeconomic characteristics between men and women but also take notice of such differences in sociocultural settings as they experience. And it will be also required to prepare any gender-differentiated intervention strategy for men and women. PMID:22304965

To evaluate the role of gender on the hearing performance of postlingually deafened adult patients with cochlear implants. Individual retrospective cohort study. There were 638 postlingually deafened adults (280 men and 358 women) selected for a retrospective evaluation of their hearing performance with cochlear implants. Both genders underwent the same surgical and rehabilitative procedures and benefited from the latest technological advances available. There was no significant difference in the age, duration of deafness, and preoperative hearing performance between the genders. The test battery was composed of the Freiburger Monosyllabic Test, Speech Tracking, and the Hochmair-Schulz-Moser (HSM) sentence test in quiet and in 10-dB noise. The results of 5 years of follow-up are presented here. Genders showed a similar performance in Freiburger Monosyllabic Test and Speech Tracking Test. However, in the HSM test in noise, men performed slightly better than women in all of the follow-up sessions, which was statistically significant at 2 and 4 years after implantation. Although normal-hearing women use more predictive cognitive strategies in speech comprehension and are supposed to have a more efficient declarative memory system, this may not necessarily lead to a better adaptation to the altered auditory information delivered by a cochlear implant. Our study showed that in more complex listening situations such as speech tests in noise, men tend to perform slightly better than women. Gender may have an influence on the hearing performance of postlingually deafened adults with cochlear implants.

Gender in Facial Representations: A Contrast-Based Study of Adaptation within and between the Sexes

Face aftereffects are proving to be an effective means of examining the properties of face-specific processes in the human visual system. We examined the role of gender in the neural representation of faces using a contrast-based adaptation method. If faces of different genders share the same representational face space, then adaptation to a face of one gender should affect both same- and different-gender faces. Further, if these aftereffects differ in magnitude, this may indicate distinct gender-related factors in the organization of this face space. To control for a potential confound between physical similarity and gender, we used a Bayesian ideal observer and human discrimination data to construct a stimulus set in which pairs of different-gender faces were equally dissimilar as same-gender pairs. We found that the recognition of both same-gender and different-gender faces was suppressed following a brief exposure of 100ms. Moreover, recognition was more suppressed for test faces of a different-gender than those of the same-gender as the adaptor, despite the equivalence in physical and psychophysical similarity. Our results suggest that male and female faces likely occupy the same face space, allowing transfer of aftereffects between the genders, but that there are special properties that emerge along gender-defining dimensions of this space.

Methamphetamine use poses increased risk for HIV and other sexually transmitted infections. There is robust evidence that methamphetamine use increases sexual risk behavior, like condomless sex, primarily among men who have sex with men but also among heterosexual women and men. Gender differences have been found among women and men who use meth, and there is a high degree of interconnectedness between meth use, depression, and condomless sex. The aims of the current study are to evaluate the efficacy of a theory-based, tri-focal intervention designed to reduce depression, meth use, and condomless sex among women and men, and to examine gender as a moderator of efficacy. A total of 432 HIV-negative women and men who use meth participated in a two-arm randomized controlled trial and completed baseline and follow-up assessments at 4, 8, and 12 months. We used latent growth curve modeling techniques to analyze the data. Results showed that while all participants exhibited reductions in depression, meth use, and condomless sex, the intervention and comparison groups did not differ in changes over time. However, we did find a significant gender moderation effect, such that among men, those in the intervention arm reported greater reductions in meth use relative to those in the comparison group; reduced meth use was associated with reduced condomless sex, but not depression. In contrast, women in the intervention condition did not differ from women in the comparison condition in changes in any of the three outcome variables. Interventions targeting heterosexual women and men who use meth must be gender-specific, and take into account the unique vulnerabilities and experiences of women, including the perceived positive aspects of using meth, gendered power dynamics, higher depression, and violence.

Objectives To survey medical students on their ideas of future work-life balance and discuss topics for next-generation medical education. Methods First-year (n=372, 34.9% female) and sixth-year medical students (n=311, 44.1% female) responded to a questionnaire on future self, marriage and childcare, and gender differences at the workplace. Responses were compared between academic years and gender. Responses were evaluated by gender and academic year using the Mann-Whitney U test. Significance was set at p<0.01. Results The first-year and sixth-year students, regardless of gender, had different views on gender-related favorable treatment at workplaces {U=13464, p=0.000 (first-year), U=10407, p=0.000 (sixth-year)}. A greater percentage of female students would choose career options based on the possibility of marriage and childbirth {U=10689, p=0.000 (first-year), U=10930, p=0.000 (sixth-year)}. Among first-year students, a greater percentage of female students expected to work part-time. Also among first-year students, greater percentages of female students expected to work part-time or leave their jobs temporarily while raising their children. Compared with first-year male students, first-year female students expected to undertake larger portions of the childcare and housework burden than their partners. However, gender differences in work-life balance and childcare leave vanished in the sixth-year students. Conclusions Female medical students accepted childcare and housework burdens as inevitable; the work environment they choose might affect their career development. While support from male partners and institutions must be increased, voluntary actions and change in mentality of female students need to be promoted through medical education to prevent them from waiting passively for the situation to change.

An increasing number of women are pursuing a career in surgery. Concurrently, the percentage of surgeons in dual-profession partnerships is increasing. We sought to evaluate the gender differences in professional advancement, work-life balance, and satisfaction at a large academic center. All surgical trainees and faculty at a single academic medical center were surveyed. Collected variables included gender, academic rank, marital status, family size, division of household responsibilities, and career satisfaction. Student t-test, Fisher's exact test, and chi-square test were used to compare results. There were 127 faculty and 116 trainee respondents (>80% response rate). Respondents were mostly male (77% of faculty, 58% of trainees). Women were more likely than men to be married to a professional (90% versus 37%, for faculty; 82% versus 41% for trainees, P < 0.001 for both) who was working full time (P < 0.001) and were less likely to be on tenure track (P = 0.002). Women faculty were more likely to be primarily responsible for childcare planning (P < 0.001), meal planning (P < 0.001), grocery shopping (P < 0.001), and vacation planning (P = 0.003). Gender-neutral responsibilities included financial planning (P = 0.04) and monthly bill payment (P = 0.03). Gender differences in division of household responsibilities were similar in surgical trainees except for childcare planning, which was a shared responsibility. Women surgeons are more likely to be partnered with a full-time working spouse and to be primarily responsible for managing their households. Additional consideration for improvement in recruitment and retention strategies for surgeons might address barriers to equalizing these gender disparities. Published by Elsevier Inc.

Sustained attentional control is critical for everyday tasks and success in school and employment. Understanding gender differences in sustained attentional control, and their potential sources, is an important goal of psychology and neuroscience and of great relevance to society. We used a large web-based sample (n = 21,484, from testmybrain.org) to examine gender differences in sustained attentional control. Our sample included participants from 41 countries, allowing us to examine how gender differences in each country relate to national indices of gender equality. We found significant gender differences in certain aspects of sustained attentional control. Using indices of gender equality, we found that overall sustained attentional control performance was lower in countries with less equality and that there were greater gender differences in performance in countries with less equality. These findings suggest that creating sociocultural conditions which value women and men equally can improve a component of sustained attention and reduce gender disparities in cognition.

Glottal area waveform (GAW) analysis is widely used in the assessment of vocal fold vibration by high-speed digital imaging (HSDI). Because normative GAW data obtained from a large number of subjects have not been reported, we conducted a prospective study to obtain normative results for GAW analysis of HSDI findings and clarify normal variations associated with gender and age. Vocally healthy adults were divided into a young group (aged ≤ 35 years) and an elderly group (aged ≥ 65 years). The configuration and size of the glottal area were assessed at different phases of the glottal cycle, and gender- and age-related differences were evaluated. A total of 26 young subjects (nine men and 17 women; mean age: 27 years) and 20 elderly subjects (eight men and 12 women; mean age: 73 years) were investigated. The glottal area at different points of the glottal cycle showed a negative correlation with frequency. Although the GAW parameters of young women appeared to be different from those of the other subgroups, the differences were not statistically significant. Young women predominantly had a triangular- or vase-shaped glottal configuration at all frequencies, whereas the other subgroups showed various glottal shapes. The present study clarified gender- and age-related differences of GAW parameters obtained with HSDI. Young women were likely to show different glottal configurations and different responses to frequency changes from those of young men, elderly men, and elderly women. Phonosurgeons should pay attention to the normal variations detected in the present study. Copyright © 2014 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

Brain-derived neurotrophic factor (BDNF) Val66Met polymorphism has been associated with cortisol responses to stress with gender differences reported, although the findings are not entirely consistent. To evaluate the role of Val66Met genotype and gender on cortisol responses to stress, we conducted a 45-min mental stress protocol including four tasks and four rest periods. Blood cortisol was collected for assay immediately before and after each task and rest period. A significant two-way interaction of Val66Met genotype×gender (P=0.022) was observed on the total area under the curve (AUC), a total cortisol response over time, such that the Val/Val genotype was associated with a larger cortisol response to stress as compared to the Met group in women but not in men. Further contrast analyses between the Val/Val and Met group for each stress task showed a similar increased cortisol pattern among women Val/Val genotype but not among men. The present findings indicate the gender differences in the effect of Val66Met genotype on the cortisol responses to stress protocol, and extend the evidence for the importance of gender and the role of Val66Met in the modulation of stress reactivity and subsequent depression prevalence. Further studies and the underlying mechanism need to be investigated, which may provide an insight for prevention, intervention, and treatment strategies that target those at high risk.

Surgical pathologists use a variety of phrases to communicate varying degrees of diagnostic certainty which have the potential to be interpreted differently than intended. This study sought to: (1) assess the setting, varieties and frequency of use of phrases of diagnostic uncertainty in the diagnostic line of surgical pathology reports, (2) evaluate use of uncertainty expressions by experience and gender, (3) determine how these phrases are interpreted by clinicians and pathologists, and (4) assess solutions to this communication problem. We evaluated 1500 surgical pathology reports to determine frequency of use of uncertainty terms, identified those most commonly used, and looked for variations in usage rates on the basis of case type, experience and gender. We surveyed 76 physicians at tumor boards who were asked to assign a percentage of certainty to diagnoses containing expressions of uncertainty. We found expressions of uncertainty in 35% of diagnostic reports, with no statistically significant difference in usage based on age or gender. We found wide variation in the percentage of certainty clinicians assigned to the phrases studied. We conclude that non-standardized language used in the communication of diagnostic uncertainty is a significant source of miscommunication, both amongst pathologists and between pathologists and clinicians.

Stepping out of the caveman's shadow: nations' gender gap predicts degree of sex differentiation in mate preferences.

PubMed

Zentner, Marcel; Mitura, Klaudia

2012-10-01

An influential explanation for gender differences in mating strategies is that the sex-specific reproductive constraints faced by human ancestors shaped these differences. Other theorists have emphasized the role of societal factors, hypothesizing, for example, that gender differences in mate preferences should wane in gender-equal societies. However, findings have been ambiguous. Using recent data and a novel measure of gender equality, we revisited the role of gender parity in gender differentiation for mate preferences. In the first study, 3,177 participants from 10 nations with a gradually decreasing Global Gender Gap Index (GGI) provided online ratings of the desirability of mate attributes with reportedly evolutionary origins. In the second study, GGI scores were related to gender differences in mate preferences previously reported for 8,953 participants from 31 nations (Buss, 1989). Both studies show that gender differences in mate preferences with presumed evolutionary roots decline proportionally to increases in nations' gender parity.
The structure of ethnic attitudes: the effects of target group, region, gender, and national identity.

PubMed

Verkuyten, M

1997-08-01

The present study was an assessment of attitudes of 410 ethnically Dutch adolescents toward three ethnic minority groups living in the Netherlands. Stereotypes, symbolic beliefs, affective associations, and the evaluation of possible interactions were used to predict the global evaluation of ethnic outgroups and accounted for much of the variance in ethnic attitudes. The relative importance of the four predictors varied by target group and location. Gender differences were found in the structure of attitudes; symbolic beliefs played a greater role in the attitudes of boys, whereas emotions played a more central role in the attitudes of girls. The evaluation of Dutch identity was related to the favorability of ethnic attitudes and also to the underlying structure. Respondents with a positive national identity had less favorable ethnic attitudes, and emotions were more predictive of their attitudes, whereas symbolic beliefs were most predictive among respondents with a less positive national identity.

Introduction: Racial and gender disparities for smoking cessation might be accounted for by differences in expectancies for tobacco interventions, but few studies have investigated such differences or their relationships with motivation to quit and abstinence self-efficacy. Methods: In this cross-sectional study, 673 smokers (African American: n = 443, 65.8%; women: n = 222, 33.0%) under criminal justice supervision who enrolled in a clinical smoking cessation trial in which all received bupropion and half received counseling. All participants completed pretreatment measures of expectancies for different tobacco interventions, motivation to quit, and abstinence self-efficacy. The indirect effects of race and gender on motivation to quit and abstinence self-efficacy through expectancies for different tobacco interventions were evaluated. Results: African Americans’ stronger expectancies that behavioral interventions would be effective accounted for their greater motivation to quit and abstinence self-efficacy. Women’s stronger expectancies for the effectiveness of pharmacotherapy accounted for their greater motivation to quit, whereas their stronger expectancies for the effectiveness of behavioral treatments accounted for their greater abstinence self-efficacy. Conclusions: Findings point to the mediating role of expectancies for treatment effectiveness and suggest the importance of exploring expectancies among African Americans and women as a way to augment motivation and self-efficacy.

Male and female students behave differently in problem-based learning (PBL) tutorials. However, these differences could be partly attributed to faculty tutor behavior in male and female tutorials. This study aims to examine the gender differences in learning outcomes between medical students when peer tutors facilitate PBL tutorials. A questionnaire-based study conducted in single-gender student-led (SLT) and faculty-led (FLT) tutorials. The study involved third year medical students (n = 91) divided into ten groups (five groups each). The SLT groups consisted of 16 male and 28 female students, while the FLT group consisted of 20 male and 27 female students. Students evaluated their individual and group performance in tutorials and also skills of tutors. Student performance in end-unit examinations and their perceptions about peer tutoring were also analyzed. A total of 290 questionnaires (response rate = 63.7%) were collected over the five-week period of the study. Although individual performance in tutorials and achievement in examinations were comparable in both groups, there was significantly higher group performance in female compared with male student-led tutorials (p < 0.01). This difference between male and female groups was not attributed to improvement in the performance of female groups, but rather to a decline in performance of the male SLT groups. In addition, both male and female students expressed facing difficulties in discussion and analysis of the problem in the first tutorial session. Understanding the gender differences in the group behavior in student-led tutorials is important for PBL programs adopting this approach.

Many studies have demonstrated the small-worldness of the human brain, and have revealed a sexual dimorphism in brain network properties. However, little is known about the gender effects on the topological organization of the brain metabolic covariance networks. To investigate the small-worldness and the gender differences in the topological architectures of human brain metabolic networks. FDG-PET data of 400 healthy right-handed subjects (200 women and 200 age-matched men) were involved in the present study. Metabolic networks of each gender were constructed by calculating the covariance of regional cerebral glucose metabolism (rCMglc) across subjects on the basis of AAL parcellation. Gender differences of network and nodal properties were investigated by using the graph theoretical approaches. Moreover, the gender-related difference of rCMglc in each brain region was tested for investigating the relationships between the hub regions and the brain regions showing significant gender-related differences in rCMglc. We found prominent small-world properties in the domain of metabolic networks in each gender. No significant gender difference in the global characteristics was found. Gender differences of nodal characteristic were observed in a few brain regions. We also found bilateral and lateralized distributions of network hubs in the females and males. Furthermore, we first reported that some hubs of a gender located in the brain regions showing weaker rCMglc in this gender than the other gender. The present study demonstrated that small-worldness was existed in metabolic networks, and revealed gender differences of organizational patterns in metabolic network. These results maybe provided insights into the understanding of the metabolic substrates underlying individual differences in cognition and behaviors. © The Foundation Acta Radiologica 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.
Social and behavioral skills and the gender gap in early educational achievement.

Diprete, Thomas A; Jennings, Jennifer L

2012-01-01

Though many studies have suggested that social and behavioral skills play a central role in gender stratification processes, we know little about the extent to which these skills affect gender gaps in academic achievement. Analyzing data from the Early Child Longitudinal Study-Kindergarten Cohort, we demonstrate that social and behavioral skills have substantively important effects on academic outcomes from kindergarten through fifth grade. Gender differences in the acquisition of these skills, moreover, explain a considerable fraction of the gender gap in academic outcomes during early elementary school. Boys get roughly the same academic return to social and behavioral skills as their female peers, but girls begin school with more advanced social and behavioral skills and their skill advantage grows over time. While part of the effect may reflect an evaluation process that rewards students who better conform to school norms, our results imply that the acquisition of social and behavioral skills enhances learning as well. Our results call for a reconsideration of the family and school-level processes that produce gender gaps in social and behavioral skills and the advantages they confer for academic and later success.

To assess the influence of peripheral neuropathy, gender, and obesity on the postural stability of patients with type 2 diabetes mellitus. 151 patients with no history of otology, neurology, or orthopaedic or balance disorders accepted to participate in the study. After a clinical interview and neuropathy assessment, postural stability was evaluated by static posturography (eyes open/closed on hard/soft surface) and the "Up & Go" test. During static posturography, on hard surface, the length of sway was related to peripheral neuropathy, gender, age, and obesity; on soft surface, the length of sway was related to peripheral neuropathy, gender, and age, the influence of neuropathy was larger in males than in females, and closing the eyes increased further the difference between genders. The mean time to perform the "Up & Go" test was 11.6 ± 2.2 sec, with influence of peripheral neuropathy, gender, and age. In order to preserve the control of static upright posture during conditions with deficient sensory input, male patients with type 2 diabetes mellitus with no history of balance disorders may be more vulnerable than females, and obesity may decrease the static postural control in both males and females.

Gender identity and gender role are expected to be consistent with gender assignment for optimal DSD management outcome. To our knowledge, our study is the first to attempt evaluation of gender related outcomes in Turkish DSD patients. After receiving institutional ethical board approval and subject (or parent) informed consent, subjects with DSD raised as girls (22 patients 46 XX DSD, 11 patients 46 XY DSD) answered 566 questions of the Minnesota Multiphasic Personality Inventory (MMPI) questionnaire including 60-item Masculinity-Femininity (MF) subscale which was the focus in this study. Controls (n: 50) were females similar to the probands in age, level of education, relationship status, and having a job or not also answered all questions. The answers were evaluated by a trained psychologist (Derya Inceoglu) on MMPI. For statistical purposes, seven findings were obtained from the data related to the MF subscale from the patients and controls. Of these seven findings (S1–S7), two were associated with masculinity (S3–S4) and another two were associated with femininity (S5–S6). In DSD patients, the percentages of masculinity findings were significantly higher when compared to controls (p < 0.001 and p < 0.001 for S3 and S4, respectively). In controls, the percentages of femininity findings were significantly higher when compared to DSD females (p < 0.001 and p < 0.001 for S5 and S6 respectively). There was no significant difference between 46 XX DSD patients and 46 XY DSD patients with respect to the percentage of any of the seven findings. Two patients requested gender change to male; only these two patients had the finding stating that sexual impulses could come to existence as actions (S7). In conclusion efforts to identify modifiable factors with negative impact and thus modifying them, and professional guidance may be important in minimizing the encountered gender related problems in DSD patients.

To review the literature on strategies implemented or identified to prevent or reduce gender bias in peer review of research grants. Studies of any type of qualitative or quantitative design examining interventions to reduce or prevent gender bias during the peer review of health-related research grants were included. Electronic databases including MEDLINE, EMBASE, Education Resources Information Center (ERIC), PsycINFO, Joanna Briggs, the Cochrane Library, Evidence Based Medicine (EBM) Reviews, and the Campbell Library were searched from 2005 to April 2016. A search for grey (i.e., difficult to locate or unpublished) literature was conducted and experts in the field were consulted to identify additional potentially relevant articles. Two individuals screened titles and abstracts, full-text articles, and abstracted data with discrepancies resolved by a third person consistently. After screening 5524 citations and 170 full-text articles, one article evaluating gender-blinding of grant applications using an uncontrolled before-after study design was included. In this study, 891 applications for long-term fellowships in 2006 were included and 47% of the applicants were women. These were scored by 13 peer reviewers (38% were women). The intervention included eliminating references to gender from the applications, letters of recommendations, and interview reports that were sent to the committee members for evaluation. The proportion of successful applications led by women did not change with gender-blinding, although the number of successful applications that were led by men increased slightly. There is limited research on interventions to mitigate gender bias in the peer review of grants. Only one study was identified and no difference in the proportion of women who were successful in receiving grant funding was observed. Our results suggest that interventions to prevent gender bias should be adapted and tested in the context of grant peer review to determine if they will have an impact.

We attempted to test if there were gender differences in nonsuicidal self-injurious (NSSI) behaviors among Chinese middle-school students, and analyze the impact of gender role conflict and violent experiences on these behaviors among middle-school students of different genders. Based on the survey data from seven middle schools in Xi'an region of China, the gender difference in NSSI behaviors and its associated factors were analyzed in this study. There was no significant gender difference in NSSI behaviors among middle-school students; however, female middle-school students were more likely to experience gender role conflicts while male students were more likely to experience all kinds of violence earlier. Gender role conflicts and violent experiences can explain the prevalence of NSSI behaviors by gender, to some extent. The hypothesis on gender patterns of "boy crisis" or "girl risk" on NSSI prevalence was not verified; however, a "girl risk" for gender role conflicts and a "boy crisis" in violent experiences were found. The gender role conflicts were significantly associated with NSSI prevalence among middle-school students to some extent; however, this relationship was adjusted by variables of violent experiences. The different variables of violent experiences were the important predictors of NSSI prevalence among male and female middle-school students with specific contents varying across genders.

To identify gender differences in career satisfaction and practice patterns among Ontario ophthalmologists. Survey mailed to all Ontario female ophthalmologists (n = 65) and a random sample of male ophthalmologists (n = 72). Men reported performing more operations per month (p = 0.039) and more operations in the last typical year (p = 0.003). More men than women were doing laser refractive surgery (p = 0.004). There were no gender differences in the proportion performing eye surgery or in the hours worked per week or weeks worked per year. Women reported being primarily responsible for their children for significantly more hours per week than men (p = 0.0003). There were no gender differences in any of the parameters of career satisfaction evaluated: number of hours worked, number of hours in the operating room (OR), balance with personal life, flexibility of work schedules, ability to structure work, relationship with colleagues and relationship with OR staff. Despite spending significantly more hours as the primary supervisor of their children, female ophthalmologists were maintaining the same work week as their male colleagues and reported equal career satisfaction. Further investigation is needed to explore the differences between male and female ophthalmologists in the reported number of operations performed.
