    Neuromarketing is a multidisciplinary field of research whose aim is to investigate the consumers' reaction to advertisements from a neuroscientific perspective. In particular, the neuroscience field is thought to be able to reveal information about consumer preferences which are unobtainable through conventional methods, including submitting questionnaires to large samples of consumers or performing psychological personal or group interviews. In this scenario, we performed an experiment in order to investigate cognitive and emotional changes of cerebral activity evaluated by neurophysiologic indices during the observation of TV commercials. In particular, we recorded the electroencephalographic (EEG), galvanic skin response (GSR), and heart rate (HR) in a group of 28 healthy subjects during the observation of a series of TV advertisements that have been grouped by commercial categories. Comparisons of cerebral indices have been performed to highlight gender differences between commercial categories and scenes of interest of two specific commercials. Findings show how EEG methodologies, along with the measurements of autonomic variables, could be used to obtain hidden information to marketers not obtainable otherwise. Most importantly, it was suggested how these tools could help to analyse the perception of TV advertisements and differentiate their production according to the consumer's gender. PMID:25147579

    Whether men and women are fundamentally different or similar has been debated for more than a century. This review summarizes major theories designed to explain gender differences: evolutionary theories, cognitive social learning theory, sociocultural theory, and expectancy-value theory. The gender similarities hypothesis raises the possibility of theorizing gender similarities. Statistical methods for the analysis of gender differences and similarities are reviewed, including effect sizes, meta-analysis, taxometric analysis, and equivalence testing. Then, relying mainly on evidence from meta-analyses, gender differences are reviewed in cognitive performance (e.g., math performance), personality and social behaviors (e.g., temperament, emotions, aggression, and leadership), and psychological well-being. The evidence on gender differences in variance is summarized. The final sections explore applications of intersectionality and directions for future research. PMID:23808917

    Objective Evidence supporting the continuity between child temperament and adult personality traits is accumulating. One important indicator of continuity is the presence of reliable gender differences in traits across the lifespan. A substantial literature demonstrates gender differences on certain adult personality traits and recent meta-analytic work on child samples suggests similar gender differences for some broad and narrow domains of temperament. However, most existing studies of children rely only on parent-report measures. The present study investigated gender differences in temperament traits assessed by laboratory observation, maternal-report, and paternal-report measures. Methods Across three independent samples, behavioral observations, maternal-report, and paternal-report measures of temperament were collected on 463 boys and 402 girls. Results Across all three methods, girls demonstrated higher positive affect and fear and lower activity level than boys. For laboratory measures, girls demonstrated higher levels of sociability and lower levels of overall negative emotionality (NE), sadness, anger and impulsivity than boys. However, girls demonstrated higher levels of overall NE and sadness than boys when measured by maternal reports. Finally, girls demonstrated lower levels of sociability based on paternal reports. Conclusions Results are discussed in relation to past meta-analytic work and developmental implications of the findings. PMID:22924826

    In an assessment of gender differences in schizophrenia, 85 outpatients (53 men and 32 women) with schizophrenia were evaluated for illness history, symptom severity, IQ, neurocognitive status, cerebral volume loss, and cortical asymmetry. Social functioning was assessed using marital status, independent living skills, and employment status. Significant gender differences were found, as women were on lower doses of neuroleptic medications and more frequently met criteria for paranoid and disorganized subtypes of schizophrenia than men. Women also were better educated and more often married, living independently, and employed. No gender differences were found in present age, symptom severity, neurocognitive functioning, or clinical magnetic resonance imaging scan readings. Our findings suggest that women may experience less of the adverse interpersonal psychosocial consequences of schizophrenia than men, even when symptom and neurocognitive status is equivalent between groups. However, more extensive investigations are warranted to better understand the role of pathophysiological or social mechanisms in gender differences. PMID:7643064

    Introduction Impact of gender on severe infections is in highly controversial discussion with natural survival advantage of females described in animal studies but contradictory to those described human data. This study aims to describe the impact of gender on outcome in mixed intensive care units (ICUs) with a special focus on sepsis. Methods We performed a prospective, observational, clinical trial at Charité University Hospital in Berlin, Germany. Over a period of 180 days, patients were screened, undergoing care in three mainly surgical ICUs. In total, 709 adults were included in the analysis, comprising the main population ([female] n = 309, [male] n = 400) including 327 as the sepsis subgroup ([female] n = 130, [male] n = 197). Results Basic characteristics differed between genders in terms of age, lifestyle factors, comorbidities, and SOFA-score (Sequential Organ Failure Assessment). Quality and quantity of antibiotic therapy in means of antibiotic-free days, daily antibiotic use, daily costs of antibiotics, time to antibiotics, and guideline adherence did not differ between genders. ICU mortality was comparable in the main population ([female] 10.7% versus [male] 9.0%; P = 0.523), but differed significantly in sepsis patients with [female] 23.1% versus [male] 13.7% (P = 0.037). This was confirmed in multivariate regression analysis with OR = 1.966 (95% CI, 1.045 to 3.701; P = 0.036) for females compared with males. Conclusions No differences in patients' outcome were noted related to gender aspects in mainly surgical ICUs. However, for patients with sepsis, an increase of mortality is related to the female sex.

    The potential effect of gender on intellectual abilities remains controversial. The purpose of this research was to analyze gender differences in cognitive test performance among children from continuous age groups. For this purpose, the normative data from 7 domains of the newly developed neuropsychological test battery, the Evaluación Neuropsicológica Infantil [Child Neuropsychological Assessment] (Matute, Rosselli, Ardila, & Ostrosky-Solis, 2007), were analyzed. The sample included 788 monolingual children (350 boys, 438 girls) ages 5 to 16 years from Mexico and Colombia. Gender differences were observed in oral language (language expression and language comprehension), spatial abilities (recognition of pictures seen from different angles), and visual (Object Integration Test) and tactile perceptual tasks, with boys outperforming girls in most cases, except for the tactile tasks. Gender accounted for only a very small percentage of the variance (1%-3%). Gender x Age interactions were observed for the tactile tasks only. It was concluded that gender differences during cognitive development are minimal, appear in only a small number of tests, and account for only a low percentage of the score variance. PMID:21744957

    Depression is one of the most prevalent and debilitating diseases. In recent years there has been increased awareness of sex- and gender-specific issues in depression. This narrative review presents and discusses differences in prevalence, symptom profile, age at onset and course, comorbidity, biological and psychosocial factors, the impact of sexual stereotyping, help-seeking, emotion regulation and doctor-patient communication. Typically, women are diagnosed with depression twice as often as men, and their disease follows a more chronic course. Comorbid anxiety is more prevalent in women, whereas comorbid alcohol abuse is a major concern in men. Sucide rates for men are between three and five times higher compared with women. Although there are different symptom profiles in men and women, it is difficult to define a gender-specific symptom profile. Socially mediated gender roles have a significant impact on psychosocial factors associated with risk, sickness behavior and coping strategies. In general, too little attention has been paid to the definition and handling of depression and the gender-related requirements it makes on the healthcare system. PMID:25070409

  19. Gender Differences in Cardiovascular Drugs.

    Stolarz, Amanda J; Rusch, Nancy J

    2015-08-01

    The different responses of women and men to cardiovascular drugs reflect gender -specific variances in pharmacokinetic profiles and drug sensitivities coupled to inherent differences in the underlying physiology of each sex. Thus, many common cardiovascular drugs exhibit gender -specific therapeutic and adverse effects. For example, the QT interval of the electrocardiogram is longer in women compared to men, and accordingly, drugs that prolong the QT interval are more likely to cause lethal ventricular arrhythmias in female than male patients. As more clinical drug trials include women subjects, our improved knowledge base for assessing the risk/benefit ratio for cardiovascular drugs in women will enable us to consider gender as one factor in prescribing drugs and adjusting drug loading and maintenance dosages. This short review will present evidence for gender- related differences in the responses to common cardiovascular drugs including statins, antiplatelet and antithrombotic agents, β-blockers, digoxin, vasodilator therapies, and drugs associated with the Long QT Syndrome.

    2013-02-01

    We investigated gender differences in the identification of personally familiar voices in a gender-balanced sample of 40 listeners. From various types of utterances, listeners had to identify by name 20 speakers (10 female) among a set of 70 possible classmates who were all 12th grade pupils from the same local secondary school. Mean identification rates were 67% from sentences, and around 35% for an isolated /Hello/ or a VCV syllable. Even from non-verbal harrumphs, speakers were identified with an accuracy of 18%, i.e. highly above chance levels. Substantial individual differences were observed between listeners. Importantly, superior overall performance of female listeners was qualified by an interaction between voice gender and listener gender. Male listeners exhibited an own-gender bias (i.e. better identification for male than female voices), whereas female listeners identified voices of both genders at similar levels. Individual own-gender identification biases were correlated with differences in reported contact to a speaker's voice and voice distinctiveness. Overall, the present study establishes a number of factors that account for substantial individual differences in personal voice identification. PMID:23168357

    We discuss about the gender difference of cerebrovascular disease according to the data of Japan Standard Stroke Registry Study. The male proportion was dominant in cerebrovascular disease except for subarachnoid hemorrhage(SAH). According to the data of Ministry of Health, Labour and Welfare, age-adjusted death rate in cerebral infarction and intracerebral hemorrhage were higher in male than in female, however, in SAH the rate was no different between male and female. The incidence of SAH is higher in women than in men, but this gender difference emerges not earlier than age 59. Most cases of SAH were occurring in the ages ranging from 50's in male and 70's in female. The total male-to-female ratio was approximately 1:2. The female proportion was dominant in older patients.

    This study examines gender differences in defensive style across the domains of work and intimate relationships. Participants (47 women and 38 men) completed two versions (work-related; interpersonally related) of Bond's (1983) Defense Style Questionnaire (DSQ). Results showed that, while all participants use primarily mature defenses, they are significantly more likely to use immature defenses in love than at work; men are also significantly more likely than women to use immature defenses at work. In addition, women report significantly more use of intermediate defenses than men at work, while men report significantly more use of intermediate defenses than women in love. Results are discussed in light of Chodorow's (1978) theory of gender differences in development. PMID:12064033

    The relationship between mental illness, on the one hand, and sex and gender, on the other hand, has received interest since the beginning of medicine in antique times. A prototypical example of a seemingly woman-specific disease is hysteria. The term itself, which is derived from the Greek word for womb, denotes a psychosexual dimension comprising the current attitude towards sexuality and the dominating gender relationship. In addition, the colourful history of hysteria indicates that illness is not exclusively determined by biological factors, but also significantly by socio-cultural influences, for example in the treatment of hysterical women. Even nowadays, there is a wide-spread belief that dissociative symptoms and disorders, which have succeeded hysteria in current classification systems, are predominantly seen in women. However, empirical studies in the general population and in different clinical samples using sound instruments have indicated that dissociative symptoms do not differ between the genders. The seemingly dominance of dissociative disorders in women may also depend on the socio-cultural context, because men with dissociative disorders usually do not enter the general health system, but rather the legal system, i.e. they can be found in jail or forensic institutions.

    Objectives This purpose of this study was to explore the following question: Are there gender differences among older individuals with a history of heroin addiction with regard to social and family relationships and health problems? Methods Eight gender-specific focus groups were conducted with 38 (19 women, 19 men) older (50+ years) individuals with long-term histories of heroin dependence. Four groups were conducted in a methadone maintenance (MM) clinic and four groups were derived from the Los Angeles community. Results Modest gender differences were observed, but mainly in the focus-group dynamics. Women typically described the impact of their addiction on their families, while men typically described their surprise at still being alive. Hepatitis C was the primary health concern in all groups; mental health issues were also discussed. Discussion Remarkable gender differences were not apparent in the qualitative experiences of these participants. Instead, we found overriding similarities related to the interactive effects of drug use and aging. Longitudinal studies of this population as they age and interact with the health-care system and other social systems will help to untangle the complicated relationship between aging, drug addiction, gender, and health.

    Collaboration plays an increasingly important role in research productivity and impact. However, it remains unclear whether female and male researchers in science, technology, engineering and mathematical (STEM) disciplines differ significantly from each other in their collaboration propensity. Here, we report on an empirical analysis of the complete publication records of 3,920 faculty members in six STEM disciplines at selected top U.S. research universities. We find that while female faculty have significantly fewer co-authors over their careers, this can be fully explained by their lower number of publications. Indeed, we also find that females tend to distribute their co-authoring opportunities among their co-authors more evenly than males do. Our results suggest that females have had a greater propensity to collaborate, in order to succeed in a historically men-dominated academic world. Surprisingly, we find evidence that in molecular biology there has been a gender segregation within sub-disciplines. Female faculty in molecular biology departments tend to collaborate with smaller teams and publish in journals and fields where typical team size is smaller. Our results identify gender-specific collaborative behaviors as well as disciplines with distinct patterns.

    Summary The concept that the brain differs in make-up between males and females is not new. For example, it is well-established that anatomists in the nineteenth century found sex differences in human brain weight. The importance of sex differences in the organization of the brain cannot be overstated as they may directly affect cognitive functions, such as verbal skills and visio-spatial tasks in a sex-dependent fashion. Moreover, the incidence of neurological and psychiatric diseases is also highly dependent on sex. These clinical observations reiterate the importance that gender must be taken into account as a relevant possible contributing factor in order to understand the pathogenesis of neurological and psychiatric disorders. Gender-dependent differentiation of the brain has been detected at every levels of organization: morphological, neurochemical, and functional, and have been shown to be primarily controlled by sex differences in gonadal steroid hormone levels during perinatal development. In this review, we discuss how the gonadal steroid hormone testosterone and its metabolites, affect downstream signaling cascades, including gonadal steroid receptor activation, and epigenetic events in order to differentiate the brain in a gender-dependent fashion.

    2014-01-01

    A recent meta-analysis showed a robust gender difference in nightmare frequency of medium effect size in adolescents and young adults: Women tend to report nightmares more frequently than men. The present study, carried out in an unselected student sample, indicates that 2 factors mediate the gender difference in nightmare frequency: neuroticism and overall dream recall frequency. The effect of neuroticism on the gender difference and the finding that the gender difference in nightmare frequency emerges at an age of about 10 years suggest that gender-specific socialization processes may play an important role in explaining the gender differences in nightmare frequency in adolescents and young to middle-aged adults. This idea is supported by the previous finding that nightmare frequency is related to sex role orientation. However, longitudinal studies are necessary to validate these hypotheses. PMID:24934011

    Despite the widely held belief that men are more narcissistic than women, there has been no systematic review to establish the magnitude, variability across measures and settings, and stability over time of this gender difference. Drawing on the biosocial approach to social role theory, a meta-analysis performed for Study 1 found that men tended to be more narcissistic than women (d = .26; k = 355 studies; N = 470,846). This gender difference remained stable in U.S. college student cohorts over time (from 1990 to 2013) and across different age groups. Study 1 also investigated gender differences in three facets of the Narcissistic Personality Inventory (NPI) to reveal that the narcissism gender difference is driven by the Exploitative/Entitlement facet (d = .29; k = 44 studies; N = 44,108) and Leadership/Authority facet (d = .20; k = 40 studies; N = 44,739); whereas the gender difference in Grandiose/Exhibitionism (d = .04; k = 39 studies; N = 42,460) was much smaller. We further investigated a less-studied form of narcissism called vulnerable narcissism-which is marked by low self-esteem, neuroticism, and introversion-to find that (in contrast to the more commonly studied form of narcissism found in the DSM and the NPI) men and women did not differ on vulnerable narcissism (d = -.04; k = 42 studies; N = 46,735). Study 2 used item response theory to rule out the possibility that measurement bias accounts for observed gender differences in the three facets of the NPI (N = 19,001). Results revealed that observed gender differences were not explained by measurement bias and thus can be interpreted as true sex differences. Discussion focuses on the implications for the biosocial construction model of gender differences, for the etiology of narcissism, for clinical applications, and for the role of narcissism in helping to explain gender differences in leadership and aggressive behavior. Readers are warned against overapplying small effect sizes to perpetuate gender stereotypes. PMID:25546498

    Gender differences have been noted in neurobehavioral studies. The 133xenon inhalation method for measuring regional cerebral blood flow (rCBF) can contribute to the understanding of the neural basis of gender differences in brain function. Few studies have examined gender differences in rCBF. In studies of normal subjects, women have higher rates of CBF than men, and this is related to age. Usually by the sixth decade men and women have similar flow rates. Fewer studies on rCBF in schizophrenia have examined sex differences. The pattern of higher flows for females maintains, but its correlates with gender differences in clinical as well as other parameters of brain function remain to be examined.

    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

    The moral sense is among the most complex aspects of the human mind. Despite substantial evidence confirming gender-related neurobiological and behavioral differences, and psychological research suggesting gender specificities in moral development, whether these differences arise from cultural effects or are innate remains unclear. In this study, we investigated the role of gender, education (general education and health education) and religious belief (Catholic and non-Catholic) on moral choices by testing 50 men and 50 women with a moral judgment task. Whereas we found no differences between the two genders in utilitarian responses to non-moral dilemmas and to impersonal moral dilemmas, men gave significantly more utilitarian answers to personal moral (PM) dilemmas (i.e., those courses of action whose endorsement involves highly emotional decisions). Cultural factors such as education and religion had no effect on performance in the moral judgment task. These findings suggest that the cognitive-emotional processes involved in evaluating PM dilemmas differ in men and in women, possibly reflecting differences in the underlying neural mechanisms. Gender-related determinants of moral behavior may partly explain gender differences in real-life involving power management, economic decision-making, leadership and possibly also aggressive and criminal behaviors.

    PubMed

    Many drugs have act differently in women and men. Biological differences between women and men lead to sex differences in pharmacokinetics, i.e., in drug absorption, distribution in tissues, metabolism by liver enzymes, and excretion via the kidney and intestine. In addition there are sex differences in pharmacodynamics, leading to a different efficacy of drugs in women and men. The biological differences between women and men may be caused by sex-specific gene expression, by sex-specific epigenetic modifications, and finally by the effect of sex hormones. In addition, gender plays a role in drug efficacy as a sociocultural dimension that may lead to differences between women and men. Frequently drugs are only tested on animals of one sex and thereby optimized for one sex. This is based on the notion that sex differences are not important for clinical drug effects. Furthermore, to date, sex and gender differences have been underestimated in clinical studies, and phase III studies were not prospectively designed to assess sex differences in drug effects. In addition, women and men use drugs differently with respect to compliance, adherence, and self-medication with over-the-counter drugs. Further, it is known that male and female physicians treat women and men as patients differently. In conclusion, drug therapy is not yet optimized for both genders. However, there is increasing awareness that differences between women and men should be respected in order to provide optimal drugs in optimal doses for both genders. PMID:25030233

    Gender-related differences in EEE coherence were studied in young male and female university students during performance of Stroop task, in which color and word could be congruent or incongruent and spatially integrated or separated. The most clear-cut gender-related differences in the EEG coherence were revealed in the alpha2 and beta frequency bands. In the alpha2 band, gender-related differences in the interhemispheric coherence were associated with spatial characteristics of stimuli: left or right presentation and features of mutual localization of relevant and irrelevant stimuli. These differences were observed when information was addressed to the left hemisphere. Gender-related differences associated with spatial organization of stimuli were also observed for intrahemispheric beta1 coherence. Under conditions of the spatial separation of relevant and irrelevant stimuli, only females demonstrated enhancement of coherence in response to the right-side stimulus presentation as compared to the left-side presentation. It was shown that, during the differentiation of the semantic meaning of verbal stimuli, gender-related differences were caused by the features of integration of beta2 oscillators in the posterior cortical regions. The results are indicative of qualitative gender-related differences in organization of both frontoparietal and lateral attention systems in actualization of selective processes. PMID:17025190

    Demands involving the scheduling and interleaving of multiple activities have become increasingly prevalent, especially for women in both their paid and unpaid work hours. Despite the ubiquity of everyday requirements to multitask, individual and gender-related differences in multitasking have gained minimal attention in past research. In two experiments, participants completed a multitasking session with four gender-fair monitoring tasks and separate tasks measuring executive functioning (working memory updating) and spatial ability (mental rotation). In both experiments, males outperformed females in monitoring accuracy. Individual differences in executive functioning and spatial ability were independent predictors of monitoring accuracy, but only spatial ability mediated gender differences in multitasking. Menstrual changes accentuated these effects, such that gender differences in multitasking (and spatial ability) were eliminated between males and females who were in the menstrual phase of the menstrual cycle but not between males and females who were in the luteal phase. These findings suggest that multitasking involves spatiotemporal task coordination and that gender differences in multiple-task performance reflect differences in spatial ability. PMID:23462757

    2008-01-01

    Female sex has been shown to be a risk factor for clinically relevant adverse drug reactions. Is the increased risk due to sex differences in pharmacokinetics, in pharmacodynamics, or did females receive more medications and higher mg/kg doses than males? Recent studies suggest that all of the above may play a role. Generally, males weigh more than females, yet few drugs are dosed based on body weight. Drug concentrations are dependent on the volume of distribution (Vd) and clearance (Cl). Both parameters are dependent on body weight for most drugs independent of sex differences. Females have a higher percent body fat than males which can affect the Vd of certain drugs. Renal clearance of unchanged drug is decreased in females due to a lower glomerular filtration. Sex differences in activity of the cytochrome P450 (CYP) and uridine diphosphate glucuronosyltransferase (UGT) enzymes and renal excretion will result in differences in Cl. There is evidence for females having lower activity of CYP1A2, CYP2E1, and UGT; higher activity of CYP3A4, CYP2A6, and CYP2B6; and no differences in CPY2C9 and CYP2D6 activity. Pharmacodynamic changes can affect both the desired therapeutic effect of a drug as well as its adverse effect profile. The most widely reported sex difference is the higher risk in females for drug-induced long QT syndrome, with two-thirds of all cases of drug-induced torsades occurring in females. Females also have a higher incidence of drug-induced liver toxicity, gastrointestinal adverse events due to NSAIDs, and allergic skin rashes. In conclusion, at the minimum, it is important to take into account size and age as well as co-morbidities in determining the appropriate drug regiment for females, as well as males. There are still large gaps in our knowledge of sex differences in clinical pharmacology and significantly more research is needed. PMID:18929073

    Hemisphere and gender differences in mental rotation for tachistoscopically presented stimuli were assessed in 40 right-handed university students. Twenty male and 20 female subjects each were individually administered (via computer) a mental rotation task which included 10 stimulus presentations at each of eight angular disorientations (0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees) in each visual half-field (VHF) for a total of 160 trials. Analyses of variance performed on reaction time and accuracy data revealed only a main effect for orientation. A typical mental rotation function for both the left VHF and the right VHF for both genders resulted; however, no gender x visual field interaction was found. Lack of hemisphere and gender differences provide further evidence questioning the interpretation of right-hemisphere male superiority for spatial tasks. Investigation into factors such as task complexity, stimulus familiarity, and task demands may lend further insight into hemisphere and gender differences in mental rotation. PMID:8499111

    In this study, we investigated whether the first impression of a crowd of faces—crowd perception—is influenced by social background and cognitive processing. Specifically, we explored whether males and females, two groups that are distinct biologically and socially, differ in their ability to extract ensemble characteristics from crowds of faces that were comprised of different identities. Participants were presented with crowds of similar faces and were instructed to scroll through a morphed continuum of faces until they found a face that was representative of the average identity of each crowd. Consistent with previous research, females were more precise in single face perception. Furthermore, the results showed that females were generally more accurate in estimating the average identity of a crowd. However, the correlation between single face discrimination and crowd averaging differed between males and females. Specifically, male subjects' ensemble integration slightly compensated for their poor single face perception; their performance on the crowd perception task was not as poor as would be expected from their single face discrimination ability. Overall, the results suggest that group perception is not an isolated or uniform cognitive mechanism, but rather one that interacts with biological and social processes. PMID:26388805

    There is not only evidence for behavioral differences in voice perception between female and male listeners, but also recent suggestions for differences in neural correlates between genders. The fMRI functional voice localizer (comprising a univariate analysis contrasting stimulation with vocal vs. non-vocal sounds) is known to give robust estimates of the temporal voice areas (TVAs). However, there is growing interest in employing multivariate analysis approaches to fMRI data (e.g., multivariate pattern analysis; MVPA). The aim of the current study was to localize voice-related areas in both female and male listeners and to investigate whether brain maps may differ depending on the gender of the listener. After a univariate analysis, a random effects analysis was performed on female (n = 149) and male (n = 123) listeners and contrasts between them were computed. In addition, MVPA with a whole-brain searchlight approach was implemented and classification maps were entered into a second-level permutation based random effects models using statistical non-parametric mapping (SnPM; Nichols and Holmes, 2002). Gender differences were found only in the MVPA. Identified regions were located in the middle part of the middle temporal gyrus (bilateral) and the middle superior temporal gyrus (right hemisphere). Our results suggest differences in classifier performance between genders in response to the voice localizer with higher classification accuracy from local BOLD signal patterns in several temporal-lobe regions in female listeners.

    Gender-related differences in maximal leg muscle power were examined in 496 females and 426 males aged 8 to 20 years. Cycling peak power (CPP, including the force required to accelerate the flywheel of the cycle ergometer) was measured during three sprints. Optimal velocity (Vopt, velocity at CPP) was also determined. No gender-differences were observed in anthropometric characteristics and cycling performance between 8- and 14-year-old. From age 14, however, males showed a higher CPP than females, but also a higher lean leg volume (LLV, assessed by anthropometry). Allometric relationship between CPP and LLV (CPP = a . LLV ( b)) showed a clear gender-differentiation between 14- and 16-year-old: LLV exponent (b) was 1.05 in males vs. 0.74 in females. From 16 years onwards, analysis of covariance (ANCOVA) showed that the slopes of the CPP-LLV relationship were similar in both genders, but the intercepts differed. In other words, for a similar LLV, males showed greater CPP than females. It was suggested that this sex-related difference was due to total body fat increase, and more specifically lower-limb fat increase during puberty in girls, whilst the boys experienced increased lean body mass. Considering that the same gender-related difference was observed for optimal velocity adjusted for leg length, other factors such as fibre type variability or (and) neuromuscular activation might also be partly responsible for the higher peak muscle performance observed in males.

    Women currently have to face a series of additional risk factors for HIV infection, which place them at a disadvantage compared with men. These factors include economic dependence on their partners, difficulties in gaining access to accurate information on infection, prevention, diagnostic tests and counseling, gender violence, and discrimination. These difficulties are demonstrated by the growing epidemic in women, which illustrates the need to guarantee the legal, institutional, social and economic conditions that would enable action to be taken against these factors of inequality. The present article reviews the biological and social factors that influence susceptibility to infection in men and women, gender differences related to health services attendance and disease, and HIV/AIDS preventive measures from a gender perspective. The situation in Europe and the USA has been taken as a reference, although the article is mainly focused on Spain. PMID:15171844

    2013-01-01

    In prior work with adults, women were found to outperform men on a paired-associates word-learning task, but only when learning phonologically-familiar novel words. The goal of the present work was to examine whether similar gender differences in word learning would be observed in children. In addition to manipulating phonological familiarity, referent familiarity was also manipulated. Children between the ages of 5 and 7 learned phonologically-familiar or phonologically-unfamiliar novel words in association with pictures of familiar referents (animals) or unfamiliar referents (aliens). Retention was tested via a forced-choice recognition measure administered immediately after the learning phase. Analyses of retention data revealed stronger phonological and referent familiarity effects in girls than in boys. Moreover, girls outperformed boys only when learning phonologically-familiar novel words and when learning novel words in association with familiar referents. These findings are interpreted to suggest that females are more likely than males to recruit native-language phonological and semantic knowledge during novel word learning. PMID:24039377

    Background. Many neurological diseases show differences between genders. We studied gender differences in childhood Lyme neuroborreliosis (LNB) in an endemic area of Lyme borreliosis in Norway. Methods. In a population based study, all children (<14 years of age) with symptoms suspicious of LNB, including all children with acute facial nerve palsy, were evaluated for LNB by medical history, clinical examination, blood tests, and lumbar puncture. LNB was diagnosed according to international criteria. Results. 142 children were diagnosed with LNB during 2001–2009. Facial nerve palsy was more common in girls (86%) than in boys (62%) (p < 0.001), but headache and/or neck stiffness as the only symptom was more common in boys (30%) than in girls (10%) (p = 0.003). The girls were younger than boys and had a shorter duration of symptoms, but boys had a higher level of pleocytosis than girls. In a multivariate analysis, both gender and having headache and neck stiffness were associated with a higher level of pleocytosis. Conclusion. Girls and boys have different clinical presentations of LNB, and boys have a higher level of inflammation than girls independent of the clinical presentation. PMID:26576072

    Background Gender differences in spousal caregivers and their relationship to care experiences, social demographics, and caregivers’ depression were examined. Methods A stratified random sample of 2,020 users of public long-term care insurance in a city of Osaka prefecture, Japan, participated in this study. Responses from 308 spouses (56.2% wives, 43.8% husbands) were analyzed. Variables relating to care experiences, social demographics, and caregivers’ depression were compared by conducting simultaneous analyses of multiple populations. Results Wives caring for husbands had higher depression scores than husbands caring for wives. Wives tended to adopt “emotional support seeking” and “willing commitment” as coping strategies for their caregiving experience. Husband caregivers used more home-care services; however, increased service use had no effect on husbands’ depression. The availability of secondary caregivers reduced depression for caregivers, regardless of gender. Conclusions The effects on depression differed related to the caregiver's gender. Husbands relied more on family or home-care services when caring for their wives, whereas wives provided higher levels of care, positively accepted their role, and did not seek to share caregiving, but sought emotional support.

    Gender differences for adolescents in residential care were examined for a sample of 2,067 youths in a large residential facility. At admission, female youths were more troubled than male youths, as shown in significantly higher Diagnostic Interview Schedule for Children (DISC) diagnoses and comorbidity rates, higher internalizing and externalizing Child Behavior Checklist scores, and significantly higher Suicide Prevention Scale hopelessness, negative self-evaluation, and suicide ideation scores. Girls had higher rates of depressive and anxiety diagnoses on the DISC at both admission and 1 year. Both genders demonstrated significant reductions in both externalizing and internalizing problem behaviors over the first year in the program. Girls had significantly higher rates of internalizing problem behavior but showed a significantly greater reduction in these behaviors than did boys. At departure, girls were rated as being more successful than boys by clinical staff. Youths did not differ by gender in their behavior on a 6-month follow-up success scale. Implications for prioritizing research addressing the needs of female adolescents in residential care are discussed. PMID:16981810

    2013-01-01

    Background Despite the recent increase of research interest in involuntary treatment and the use of coercive measures, gender differences among coerced schizophrenia patients still remain understudied. It is well recognized that there are gender differences both in biological correlates and clinical presentations in schizophrenia, which is one of the most common diagnoses among patients who are treated against their will. The extent to which these differences may result in a difference in the use of coercive measures for men and women during the acute phase of the disease has not been studied. Methods 291 male and 231 female coerced patients with schizophrenia were included in this study, which utilized data gathered by the EUNOMIA project (European Evaluation of Coercion in Psychiatry and Harmonization of Best Clinical Practice) and was carried out as a multi-centre prospective cohort study at 13 centers in 12 European countries. Sociodemographic and clinical characteristics, social functioning and aggressive behavior in patients who received any form of coercive measure (seclusion and/or forced medication and/or physical restraint) during their hospital stay were assessed. Results When compared to the non-coerced inpatient population, there was no difference in sociodemographic or clinical characteristics across either gender. However coerced female patients did show a worse social functioning than their coerced male counterparts, a finding which contrasts with the non-coerced inpatient population. Moreover, patterns of aggressive behavior were different between men and women, such that women exhibited aggressive behavior more frequently, but men committed severe aggressive acts more frequently. Staff used forced medication in women more frequently and physical restraint and seclusion more frequently with men. Conclusions Results of this study point towards a higher threshold of aggressive behavior the treatment of women with coercive measures. This may be because less serious aggressive actions trigger the application of coercive measures in men. Moreover coerced women showed diminished social functioning, and more importantly more severe symptoms from the excitement/hostile cluster in contrast to coerced men. National and international recommendation on coercive treatment practices should include appropriate consideration of the evidence of gender differences in clinical presentation and aggressive behaviors found in inpatient populations.

    2015-01-01

    Gender medicine has been a major focus of research in recent years. The present review focuses on gender differences in the epidemiology of the most frequent ocular diseases that have been found to be associated with impaired ocular blood flow, such as age-related macular degeneration, glaucoma and diabetic retinopathy. Data have accumulated indicating that hormones have an important role in these diseases, since there are major differences in the prevalence and incidence between men and pre- and post-menopausal women. Whether this is related to vascular factors is, however, not entirely clear. Interestingly, the current knowledge about differences in ocular vascular parameters between men and women is sparse. Although little data is available, estrogen, progesterone and testosterone are most likely important regulators of blood flow in the retina and choroid, because they are key regulators of vascular tone in other organs. Estrogen seems to play a protective role since it decreases vascular resistance in large ocular vessels. Some studies indicate that hormone therapy is beneficial for ocular vascular disease in post-menopausal women. This evidence is, however, not sufficient to give any recommendation. Generally, remarkably few data are available on the role of sex hormones on ocular blood flow regulation, a topic that requires more attention in the future. PMID:24892919

    2015-04-01

    Prior research has focused on the relationship between parenthood and psychological well-being, with mixed results. Some studies have also addressed potential gender differences in this relationship, again yielding varied findings. One reason may be methodological choices pursued in these studies, including the lack of focus on combined parental roles (for example, biological parent and stepparent). The authors used data from the National Longitudinal Survey of Youth, 1979 (N = 6,276) and multinomial treatment models to address how combined roles influence depressive symptoms in mothers and fathers. Further, they explored potential gender differences. Their results indicated that having multiple parental roles is negatively associated with psychological well-being for both men and women, whereas childlessness is more negative for women, and specific parental role combinations affect mothers and fathers differently. Within the context of changing family structure in the United States, these results have important implications for social workers and other mental health professionals-particularly with regard to screening for depression among parents, who are less likely to seek mental health counseling than childless adults.

  18. Gender differences in attitudes impeding colorectal cancer screening

    PubMed Central

    2013-01-01

    Background Colorectal cancer screening (CRCS) is the only type of cancer screening where both genders reduce risks by similar proportions with identical procedures. It is an important context for examining gender differences in disease-prevention, as CRCS significantly reduces mortality via early detection and prevention. In efforts to increase screening adherence, there is increasing acknowledgment that obstructive attitudes prevent CRCS uptake. Precise identification of the gender differences in obstructive attitudes is necessary to improve uptake promotion. This study randomly sampled unscreened, screening - eligible individuals in Ontario, employing semi-structured interviews to elicit key differences in attitudinal obstructions towards colorectal cancer screening with the aim of deriving informative differences useful in planning promotions of screening uptake. Methods N = 81 participants (49 females, 32 males), 50 years and above, with no prior CRCS, were contacted via random-digit telephone dialing, and consented via phone-mail contact. Altogether, N = 4,459 calls were made to yield N = 85 participants (1.9% response rate) of which N = 4 participants did not complete interviews. All subjects were eligible for free-of-charge CRCS in Ontario, and each was classified, via standard interview by CRCS screening decision-stage. Telephone-based, semi-structured interviews (SSIs) were employed to investigate gender differences in CRCS attitudes, using questions focused on 5 attitudinal domains: 1) Screening experience at the time of interview; 2) Barriers to adherence; 3) Predictors of Adherence; 4) Pain-anxiety experiences related to CRCS; 5) Gender-specific experiences re: CRCS, addressing all three modalities accessible through Ontario’s program: a) fecal occult blood testing; b) flexible sigmoidoscopy; c) colonoscopy. Results Interview transcript analyses indicated divergent themes related to CRCS for each gender: 1) bodily intrusion, 2) perforation anxiety, and 3) embarrassment for females and; 1) avoidant procrastination with underlying fatalism, 2) unnecessary health care and 3) uncomfortable vulnerability for males. Respondents adopted similar attitudes towards fecal occult blood testing, flexible sigmoidoscopy and colonoscopy, and were comparable in decision stage across tests. Gender differences were neither closely tied to screening stage nor modality. Women had more consistent physician relationships, were more screening-knowledgeable and better able to articulate views on screening. Men reported less consistent physician relationships, were less knowledgeable and kept decision-making processes vague and emotionally distanced (i.e. at ‘arm’s length’). Conclusions Marked differences were observed in obstructive CRCS attitudes per gender. Females articulated reservations about CRCS-associated distress and males suppressed negative views while ambiguously procrastinating about the task of completing screening. Future interventions could seek to reduce CRCS-related stress (females) and address the need to overcome procrastination (males). PMID:23706029

    In prior work, women were found to outperform men on short-term verbal memory tasks. The goal of the present work was to examine whether gender differences on short-term memory tasks are tied to the involvement of long-term memory in the learning process. In Experiment 1, men and women were compared on their ability to remember phonologically-familiar novel words and phonologically-unfamiliar novel words. Learning of phonologically-familiar novel words (but not of phonologically-unfamiliar novel words) can be supported by long-term phonological knowledge. Results revealed that women outperformed men on phonologically-familiar novel words, but not on phonologically-unfamiliar novel words. In Experiment 2, we replicated Experiment 1 using a within-subjects design, and confirmed gender differences on phonologically-familiar, but not phonologically-unfamiliar stimuli. These findings are interpreted to suggest that women are more likely than men to recruit native-language phonological knowledge during novel word-learning. PMID:21392726

    The proportion of male caregivers is rapidly increasing. However, there are few large scale studies exploring gender differences in the burden or coping with caregiving. We investigated this among caregivers of patients with dementia. The study cohort consisted of 335 dyads of wife-husband couples from two studies including dementia patients and their spousal caregivers. Baseline mini-mental state examination (MMSE), clinical dementia rating scale (CDR), neuropsychiatric inventory (NPI), cornell depression scale and charlson comorbidity index (CCI) were used to describe patients with dementia, Zarit burden scale and geriatric depression scale were used to measure experienced burden and depression of caregivers. Mean age of caregivers was 78 years. There were no differences in depression, satisfaction with life, or loneliness according to caregivers' gender. Male caregivers had more comorbidities than females (CCI 1.9 versus 1.1, P < 0.001), and the wives of male caregivers had a more severe stage of dementia than husbands of female caregivers (CDR, P = 0.048; MMSE14.0 versus 17.7, P < 0.001). However, the mean Zarit burden scale was significantly lower among male than female caregivers (31.5 versus 37.5; P < 0.001). Lower education of male caregivers tended to be associated with less experienced burden. In conclusion, male caregivers of dementia experienced lower burden than female caregivers despite care recipients' more severe disease. PMID:23056990

    1990-01-01

    This study has assessed gender differences in smoking and the use of smokeless tobacco for younger adults and their parents in samples from five ethnic groups in Kenya. These samples were from two groups of pastoralists (the Maasai and the Samburu), a group engaged in fishing and farming (the Luo), and two groups of relatively Westernized Kenyans primarily involved in commercial occupations (from the Kisii and the Gikuyu ethnic groups). In four of the five study groups, there was little or no difference in the prevalence of smokeless tobacco use in either the younger or older generation. Similarly, in four of the study groups there was little or no gender difference in the prevalence of smoking for the older generation. In contrast, for the younger generation in every study group except the Luo, men were much more likely than women to smoke cigarettes. The attitudes toward tobacco use reported by the younger generation showed similar patterns. In every study group except the Luo, the younger adults reported that smokeless tobacco use was socially acceptable for both men and women, but smoking was acceptable only for men. Many of the younger women reported that they did not smoke because it would not be socially acceptable. The interview data suggest that the social prohibition against women's smoking was one component of more general restrictions on women's behavior, and the absence of restrictions on men's smoking was related to men's greater social power. The Luo were the only study group in which respondents reported that women should have as much influence as men in decision making. Correspondingly, the Luo were the only study group in which most respondents considered it acceptable for women to smoke and women were as likely as men to smoke cigarettes. PMID:2309128

    We integrate system justification and social role theory to explain how observers' system justification and target employees' gender interact to predict observers' expectations of targets' sportsmanship citizenship behaviors. In contrast with social role theory predictions, observers did not expect greater levels of sportsmanship from women compared to men. Yet observers expected more sportsmanship from women (a) when observers were ideologically motivated by gender-specific beliefs (gender-specific system justification; Study 1) and (b) when system justification was cued experimentally (Study 2). A heretofore-unexamined aspect, observers' ideology, modifies their expectations of sportsmanship citizenship across target genders. This has implications for system justification, social role, and organizational citizenship theoretical perspectives. PMID:25154113

  10. Gender differences in nightmare frequency: a meta-analysis.

    Schredl, Michael; Reinhard, Iris

    2011-04-01

    Many studies have reported gender differences in nightmare frequency. In order to study this difference systematically, data from 111 independent studies have been included in the meta-analysis reported here. Overall, estimated effect sizes regarding the gender difference in nightmare frequency differed significantly from zero in three age groups of healthy persons (adolescents, young adults, and middle-aged adults), whereas for children and older persons no substantial gender difference in nightmare frequency could be demonstrated. There are several candidate variables like dream recall frequency, depression, childhood trauma, and insomnia which might explain this gender difference because these variables are related to nightmare frequency and show stable gender differences themselves. Systematic research studying the effect of these variables on the gender difference in nightmare frequency, though, is still lacking. In the present study it was found that women tend to report nightmares more often than men but this gender difference was not found in children and older persons. Starting with adolescence, the gender difference narrowed with increasing age. In addition, studies with binary coded items showed a markedly smaller effect size for the gender difference in nightmare frequency compared to the studies using multiple categories in a rating scale. How nightmares were defined did not affect the gender difference. In the analyses of all studies and also in the analysis for the children alone the data source (children vs. parents) turned out to be the most influential variable on the gender difference (reporting, age). Other results are also presented. Investigating factors explaining the gender difference in nightmare frequency might be helpful in deepening the understanding regarding nightmare etiology and possibly gender differences in other mental disorders like depression or posttraumatic stress disorder.

    Anxiety sensitivity (AS) is the fear of anxiety-related sensations arising from beliefs that these sensations have harmful physical, psychological, or social consequences. AS is measured using the Anxiety Sensitivity Index (ASI), a 16-item self-report questionnaire. Little is known about the origins of AS, although social learning experiences (including sex-role socialization experiences) may be important. The present study examined whether there were gender differences in: (a) the lower- or higher-order factor structure of the ASI; and/or (b) pattern of ASI factor scores. The ASI was completed by 818 university students (290 males; 528 females). Separate principal components analyses on the ASI items of the total sample, males, and females revealed nearly identical lower-order three-factor structures for all groups, with factors pertaining to fears about the anticipated (a) physical, (b) psychological, and (c) social consequences of anxiety. Separate principal components analyses on the lower-order factor scores of the three samples revealed similar unidimensional higher-order solutions for all groups. Gender x AS dimension analyses on ASI lower-order factor scores showed that: females scored higher than males only on the physical concerns factor; females scored higher on the physical concerns factor relative to their scores on the social and psychological concerns factors; and males scored higher on the social and psychological concerns factors relative to their scores on the physical concerns factor. Finally, females scored higher than males on the higher-order factor representing the global AS construct. The present study provides further support for the empirical distinction of the three lower-order dimensions of AS, and additional evidence for the theoretical hierarchical structure of the ASI. Results also suggest that males and females differ on these various AS dimensions in ways consistent with sex role socialization practices. PMID:9168341

  12. Gender differences in antidepressant drug response.

    PubMed

    Keers, Robert; Aitchison, Katherine J

    2010-01-01

    Epidemiological studies suggest there are considerable differences in the prevalence and presentation of depression in men and women. Women are more than twice as likely to be diagnosed with depression and may also report more atypical and anxiety symptoms than men. Men and women also differ in the metabolism and distribution of antidepressants and the presence of oestrogen in women of childbearing age may interfere with the mechanism of action of a number of antidepressants. These differences have led many researchers to question whether antidepressants are equally effective and tolerated in men and women. While some reports suggest that selective serotonin re-uptake inhibitors (SSRIs) are more effective and result in fewer adverse drug reactions in women than tricyclic antidepressants (TCAs), gender differences in antidepressant response remains a controversial topic. The potential effects of antidepressant exposure in utero and in breast milk further complicate treatment options for antenatal and postnatal depression. While some research suggests the SSRI paroxetine is teratogenic, further carefully designed naturalistic studies are required to fully evaluate these effects. Finally, response to antidepressants and the occurrence of adverse drug reactions is marked by inter-individual variability which may be in part due to genetic differences. Future studies should therefore consider genotypes of the mother, foetus and infant in antidepressant response. PMID:21047161

    The development of safe and efficacious preventive HIV vaccines offers the best long-term hope of controlling the AIDS pandemic. Nevertheless, suboptimal uptake of safe and efficacious vaccines that already exist suggest that HIV vaccine acceptability cannot be assumed, particularly among communities most vulnerable to HIV. The present study aimed to identify barriers and motivators to future HIV vaccine acceptability among low socioeconomic, ethnically diverse men and women in Los Angeles County. Participants completed a cross-sectional survey assessing their attitudes and beliefs regarding future HIV vaccines. Hypothetical HIV vaccine scenarios were administered to determine HIV vaccine acceptability. Two-sided t-tests were performed, stratified by gender, to examine the association between vaccine acceptability and potential barriers and motivators. Barriers to HIV vaccine acceptability differed between men and women. For women, barriers to HIV vaccine acceptability were related to their intimate relationships (p<0.05), negative experiences with health care providers (p<0.05) and anticipated difficulties procuring insurance (p<0.01). Men were concerned that the vaccine would weaken the immune system (p<0.005) or would affect their HIV test results (p<0.05). Motivators for women included the ability to conceive a child without worrying about contracting HIV (p<0.10) and support from their spouse/significant other for being vaccinated (p<0.10). Motivators for men included feeling safer with sex partners (p<0.05) and social influence from friends to get vaccinated (p<0.005). Family support for HIV immunization was a motivator for both men and women (p<0.10). Gender-specific interventions may increase vaccine acceptability among men and women at elevated risk for HIV infection. Among women, interventions need to focus on addressing barriers due to gendered power dynamics in relationships and discrimination in health care. Among men, education that addresses fears and misconceptions about adverse effects of HIV vaccination on health and the importance of vaccination as one component of integrated HIV prevention may increase vaccine acceptability.

    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. PMID:23951949

    Differences between males and females in the nature of their verbal communication have been documented. The findings of this study have provided a new dimensional to those of previous research. There is support for the idea that among college graduates with similar communication skills, females use written communication as a means of establishing rapport more than males. In a voluntary, relatively unstructured task, females tend to write longer responses and to express themselves by complete thoughts (sentences). Females are also more likely to use first person singular pronouns and first person singular possessive adjectives. There is no support in this situation for gender differences in offering solutions to described program weaknesses. The length of the open-ended responses describing weaknesses and strengths are more closely related to each other than they are to ratings of program satisfaction. This study was unique in that it was based on written communication of college graduates in a voluntary task. Differences in findings from of those of other studies may be due to experience and education of the participants. 7 refs., 2 tabs.

    This study evaluated gender variability in platelet aggregation in response to common agonists. Platelet aggregation was measured in 36 healthy men and women free of any antiplatelet medication, aged 22-36 years, of Caucasian (White not of Hispanic origin), Hispanic, and African-American not of Hispanic origin. In this ex-vivo study, we investigated platelet aggregation in response to adenosine-5'-diphosphate (ADP), epinephrine (EPI), arachidonic acid (AA) and collagen (COL), using a platelet ionized calcium aggregometer (Chrono-Log Co.). Platelet aggregation response to all tested agonists was higher in females than in males regardless of ethnicity. The most significant differences were observed with collagen (P < 0.01). Among the ethnic groups, Caucasian women were most prone to platelet aggregation. Gender is a determinant of agonist effects on platelet aggregability in healthy subjects. PMID:20039102

  2. [Failure effects and gender differences in perfectionism].

    PubMed

    Masson, A M; Cadot, M; Ansseau, M

    2003-01-01

    Perfectionism is a dimension which has been studied very little as a separate entity. It is not even considered as a nosological factor. No classification of the medical sciences underlines its importance other than to speak of a personality trait, of an aspect, or of a parameter. Nevertheless, perfectionism is related to multiple disorders such as depression (18, 20, 36), suicide (8, 16, 55), nutritional problems (11, 28), anxiety (3), obsessive-compulsive personality disorder (53), social phobia (2), as well as insomnia (46). Certain authors stress the possible role of perfectionism in the development or the persistence of a substantial number of these disorders (7, 22, 38). Given these facts, it is all the easier to understand the interest shown by clinicians and researchers in the subject. Better detection and evaluation of its impact on behaviour is important in putting therapies in place (6, 53). Relationships between perfectionism and fear of failure have been approached (21, 51, 54). Correlations between perfectionism and high levels of state and trait anxiety have been demonstrated (23). The evaluation of perfectionism has been dealt with very little. Some questionnaires devote a sub-category to it, such as the Eating Disorder Inventory and the Irrational Beliefs Test. However, recently, it has been recognized that perfectionism is a multidimensional construct. Two Multidimensional Perfectionism Scales have been developed and investigated in relative isolation. Frost, Marten, Lahart and Rosenblate defined perfectionism as the setting of excessively high standards for performance associated with critical self-evaluation. Six dimensions are described: concern over making mistakes, high personal standards, parental expectations, parental criticism, doubt about quality of performance and organization. Internal consistency and validity have been established (25, 26). Hewitt and Flett (30, 31, 33, 35) have developed another approach where three dimensions of perfectionism are described: SOP (Self Oriented Perfectionism) related to high standards and self criticism, SPP (Socially Prescribed Perfectionism) related to the need of approval from others and fear of negative evaluation, OOP (Other-Oriented Perfectionism) reflecting a tendency to set high expectations for others and to evaluate them in a demanding way; this component is related, especially for males, to self-esteem, hostility and authoritarianism. Validity and internal consistency have been established too (30, 31, 35). The Frost and al's Multidimensional Perfectionism Scale and the Hewitt and Flett's scales are closely associated, except concerning the OOP. Because this component could provide new information, we have chosen the second scale, referring to the French translation and validation of Labrecque (45). EMP is the French name of MPS; it is a self-report questionnaire of 45 questions, in fact three subscales of 15 items rated on a 7-point Likert-type scale. MPS was administered to 617 first year students at the university of Liège (table II). Differences are considered according to gender and experience of failure i.e. the fact of repeating an academic year. We realized a component analysis with promax rotation. Among the different possibilities offered by the scree-test the choice of a 4 factor solution stresses the original structure: SOP (14 items), SPP (12 items), OOP (9 items) and anti OOP (10 items); the last one is additional but allows for respecting semantics and saturation of the items. The first aim of confirming validity and internal consistency is satisfactory. In other respects the multidimensional structure of the concept leads to consideration of a positive, adaptive perfectionism and a more negative perfectionism, facilitating psychopathology (59, 60, 61). So it seems interesting to compare the different components of MPS in order to find an eventual sex-failure effect. The evaluation of perfectionism is obvious, considering it as a personality trait, but it can be used also in taking into account stress and its impact, for instance that of academic performance (29, 37, 39, 58). Conferring on MPS more pertinence in gender differentiation and failure evaluation is an other goal of this research. Through the particular choice of statistical results, sex and sex-failure effects can be demonstrated: a MANOVA underlines sex effect (lambda de Wilks = 0.96, p = 0.001) and sex-failure effect (lambda de Wilks = 0.98, p = 0.05). Structure of MPS is different in four groups (FE: women with failure, FnE: women without failure, ME: men with failure, MnE: men without failure). ANOVA show differences of MPS3, MPS1 and MPS2. Far more promising is the use of LISREL method allowing for the construction of a coherent model of relationships between some dimensions of MPS and Test-Anxiety, approached here with THEE (test d'habileté aux études et à leur évaluation) French abbreviated version (49) of TASTE (Test for Ability to Study and Evaluation). In fact according to the literature of fear of failure, girls score higher on anxiety and procrastination but less on self-confidence. The structural model shows different pathways, more especially between SPP (socially prescribed perfectionism), T2 (sense of incompetence) and T1 (anxiety). SOP (self oriented perfectionism) and SPP (socially prescribed perfectionism) by girls are very much correlated; it seems that they are more subjected to society and its exigencies of studying but consequently they are more at risk of anxiety and a sense of incompetence. SOP (self oriented perfectionism) by boys functions more indiscriminately of SPP (socially prescribed perfectionism) and is negatively correlated with self-incompetence; boys are more self-confident but they usually procrastinate more probably because failure expectancies would be particularly harmful for their self-esteem; consequently, failure should be related to something else than their own capacity; this may be an explanation of the high rate of male dropouts and failure in the first year at the university of Liège; also a factor explaining the female domination at the university. In the same way the first choice of studies is moving towards shorter and less difficult orientation (46). In case of failure the model is very similar according to gender: SOP (self oriented perfectionism) and T1 (anxiety) are directly connected; SOP and SPP are in this case better correlated by boys but the path between SPP, sense of incompetence and anxiety is less significant than in girls. In conclusion, providing some modifications according to semantics, the choice of a four factor solution allows for confirmation of the original structure of MPS and for internal consistency. The different components of MPS vary according to gender: SOP and more OOP discriminate men and women; SPP allows for differentiating women with failure. A structural model enhances the role of perfectionism in the cognitive and behavioural contexts; for instance it clarifies its action on fear of failure and success rates according to gender.

    We investigate gender gaps in political participation with 2004 ISSP data for 18 advanced Western democracies (N: 20,359) using linear and logistic regression models. Controlling for socio-economic characteristics and political attitudes reveals that women are more likely than men to have voted and engaged in ‘private’ activism, while men are more likely to have engaged in direct contact, collective types of actions and be (more active) members of political parties. Our analysis indicates that demographic and attitudinal characteristics influence participation differently among men and among women, as well as across types of participation. These results highlight the need to move toward a view of women engaging in differing types of participation and based on different characteristics. PMID:20407575

    The aims of the study were (1) to investigate gender differences in pornography consumption among Danish adults aged 18-30 and (2) to examine gender differences in situational, interpersonal, and behavioral characteristics of pornography consumption. A national survey study was conducted using a representative sample of 688 young heterosexual Danish adult men and women. The study found large gender differences in prevalence rates of pornography consumption and consumption patterns. Compared to women, men were exposed to pornography at a younger age, consumed more pornography as measured by time and frequency, and used pornography more often during sexual activity on their own. Gender differences in the interpersonal context of use were also evident, with women using pornography more often with a regular sexual partner than men. In turn, men were found to use pornography more often on their own or with friends (non-sexual partners) than women. For both men and women, the usual place of use was home and no significant gender difference was found in this regard. Men and women were found to vary in their preferences in pornographic materials, with men both preferring a wider range of hardcore pornography and less softcore pornography than women. Gender differences in sexual behavioral factors were limited to masturbation patterns with men masturbating more than women. Male gender, higher frequency of masturbation, lower age at first exposure, and younger age were found to account for 48.8% of the total variance of pornography consumption. The results were discussed in relation to the sociocultural environment and evolutionary theory. It is argued that gender differences in social acceptability, adherence to gender stereotypes, traditions of gender sexuality, gender norms, and mating strategies are key factors in understanding gender differences in pornography consumption.

    To identify age and gender differences among teen drivers in fatal crashes, we analyzed FARS data for 14,026crashes during 2007-2009. Compared with female teenagers, crashes of male teenagers were significantly more likely to involve BACs of 0.08% or more (21% vs. 12%), speeding (38% vs. 25%), reckless driving (17% vs. 14%), night driving (41% vs. 36%) and felony crashes (hit-and-run, homicide, or manslaughter) (8% vs. 6%) (all χ(2) p<0.001). Conversely, crashes of female teenagers were more likely to involve right angle ("t-bone") crashes (23% vs. 17%). Some crash characteristics associated with males and known to play a major role in crash causation also are more common in the youngest teenagers; for example, crashes of drivers age 15 or 16 were more likely than crashes of older teens to involve speeding or reckless driving. Crashes of drivers with BACs of 0.08% or higher increased with age in both genders. Some age effects differed by gender: for example, the proportion of crashes of female teens that involved speeding dropped from 38% to 22% between ages 15 and 19, while for males about 38% of crashes at each age involved speeding. The gender and age differences observed in teen drivers suggest opportunities for targeted driver training - for example, simulator training modules specifically tailored for male or female teenagers. Technology-based tools could also be developed to help parents to focus on the reckless driving tendencies of their sons. Insurance companies should consider ways to incentivize young males to drive more responsibly. PMID:23169121

    Low current transcranial electrical stimulation (tCS) is an effective but somewhat inconsistent tool for augmenting neuromodulation. In this study, we used 3D MRI guided electrical transcranial stimulation modeling to estimate the range of current intensities received at cortical brain tissues. Combined T1, T2, and proton density MRIs from 24 adult subjects (12 male and 12 female) were modeled with virtual electrodes placed at F3, F4, C3, and C4. Two sizes of electrodes 20?mm round and 50?mm??45?mm were examined at 0.5, 1, and 2?mA input currents. The intensity of current received was sampled in a 1-cm sphere placed at the cortex directly under each scalp electrode. There was a 10-fold difference in the amount of current received by individuals. A large gender difference was observed with female subjects receiving significantly less current at targeted parietal cortex than male subjects when stimulated at identical current levels (P?differences in current levels that the subjects received. Analysis of the cranial bone showed that the gender difference and the frontal parietal differences are due to differences in cranial bone. Males have more cancelous parietal bone and females more dense parietal bone (P?differences should be considered when planning tCS studies and call into question earlier reports of gender differences due to hormonal influences.

Looking at recent Latin American immigrants to New York City, the article argues that immigrant Latino men are more likely to favor continuity in patterns of socialization and organization, and immigrant Latinas are more likely to favor change. This finding helps bridge theoretical and empirical literatures in immigration studies, applying the logic of gender-differentiated decisionmaking to the area of immigrant political socialization and behavior."

    2009-01-01

    The present research examined developmental and gender differences in the relative accessibility of different gender stereotype domains. A 1988 Northeastern US sample of 256 children ages 3 to 10 years old provided open-ended descriptions of girls and boys. Responses were coded by domain to examine differences by grade, gender of participant, and gender of target. Analyses revealed that girls and older children provided a higher proportion of stereotypes, and that appearance stereotypes were particularly prevalent in descriptions of girls and activity/trait stereotypes were more prevalent in descriptions of boys. Results are discussed in terms of implications for research on the stereotype knowledge–behavior link and the need for more attention to the role of appearance stereotypes in the gender stereotype literature.

  15. Gender differences in autoimmunity associated with exposure to environmental factors

    PubMed Central

    Pollard, K. Michael

    2011-01-01

    Autoimmunity is thought to result from a combination of genetics, environmental triggers, and stochastic events. Gender is also a significant risk factor with many diseases exhibiting a female bias. Although the role of environmental triggers, especially medications, in eliciting autoimmunity is well established less is known about the interplay between gender, the environment and autoimmunity. This review examines the contribution of gender in autoimmunity induced by selected chemical, physical and biological agents in humans and animal models. Epidemiological studies reveal that environmental factors can be associated with a gender bias in human autoimmunity. However many studies show that the increased risk of autoimmunity is often influenced by occupational exposure or other gender biased activities. Animal studies, although often prejudiced by the exclusive use of female animals, reveal that gender bias can be strain specific suggesting an interaction between sex chromosome complement and background genes. This observation has important implications because it argues that within a gender biased disease there may be individuals in which gender does not contribute to autoimmunity. Exposure to environmental factors, which encompasses everything around us, adds an additional layer of complexity. Understanding how the environment influences the relationship between sex chromosome complement and innate and adaptive immune responses will be essential in determining the role of gender in environmentally-induced autoimmunity.

  16. Unpacking Gender Differences in Students' Perceived Experiences in Introductory Physics

    Kost, Lauren E.; Pollock, Steven J.; Finkelstein, Noah D.

    2009-11-01

    Prior research has shown, at our institution: 1) males outperform females on conceptual assessments (a gender gap), 2) the gender gap persists despite the use of research-based reforms, and 3) the gender gap is correlated with students' physics and mathematics background and prior attitudes and beliefs [Kost, et al. PRST-PER, 5, 010101]. Our follow-up work begins to explore how males and females experience the introductory course differently and how these differences relate to the gender gap. We gave a survey to students in the introductory course in which we investigated students' physics identity and self-efficacy. We find there are significant gender differences in each of these three areas, and further find that these measures are weakly correlated with student conceptual performance, and moderately correlated with course grade.

  17. Gender differences in pharmacokinetics and pharmacodynamics of methadone substitution therapy

    Graziani, Manuela; Nisticò, Robert

    2015-01-01

    Gender-related differences in the pharmacological effects of drug are an emerging topic. This review examines gender differences in both pharmacokinetic and pharmacodynamic aspects of methadone, a long-acting opioid agonist that is prescribed as a treatment for opioid dependence and the management of chronic pain. Method: We performed a search in the Medline database from 1990 to 2014 in order to find published literature related to gender differences in pharmacokinetics (PK) and pharmacodynamics (PD) of methadone. Results: None of the studies were carried out with the primary or secondary aim to identify any gender differences in the pharmacokinetic profile of methadone. Importantly; high inter-subjects variability in PK parameters was found also intra female population. The reported differences in volume of distribution could be ascribed to the physiological differences between men and women in body weight and composition, taking into account that the dose of methadone was established irrespective of body weight of patients (Peles and Adelson, 2006). On the other hand, the few studies present in literature found no gender difference in some direct pharmacodynamic parameters. Some reports have suggested that female gender is associated with an increased risk for long-QT-related cardiac arrhythmias in methadone maintenance subjects. Conclusion: Even though it may be too simplistic to expect variability only in one parameter to explain inter-individual variation in methadone response, we believe that a better knowledge of gender-related differences might have significant implications for better outcomes in opioid dependence substitution therapy in women.

    DiBiase, Rosemarie; Gunnoe, Jaime

    2004-02-01

    The authors used gender and culture to examine the theory that touching behavior is an expression of dominance. Participants were 120 men and women from Italy, the Czech Republic, and the United States. The authors examined both hand touches and nonhand touches. For hand touches, there was a significant gender-by-culture interaction in that Czech men as a group touched more than any of the other groups. For nonhand touches, Czech and Italian women and Italian men as groups touched significantly more than any of the other groups. Taken in cultural context, these results seem to support the dominance theory for touches with the hand but not for nonhand touches. The authors discussed implications and future directions.

    The abdominal aorta (AA) is predisposed to development of abdominal aneurysms (AAA), a focal dilatation with fatal consequences if left untreated. The blood flow patterns is thought to play an important role in the development of AAA. The purpose of this work is to investigate the blood flow patterns within a group of healthy volunteers (six females, eight males) aged 23 to 76 years to identify changes and differences related to age and gender. The healthy volunteers were categorized by gender (male/female) and age (below/above 35 years). Subject-specific flow and geometry data were acquired using the research interface on a Profocus ultrasound scanner (B-K Medical, Herlev, Denmark; segmentation of 3D magnetic resonance angiography (Magnetom Trio, Siemens Healthcare, Erlangen, Germany). The largest average diameter was among the elderly males (19.7 (+/- 1.33) mm) and smallest among the young females (12.4 (+/- 0.605) mm). The highest peak systolic velocity was in the young female group (1.02 (+/- 0.336) m/s) and lowest in the elderly male group (0.836 (+/- 0.127) m/s). A geometrical change with age was observed as the AA becomes more bended with age. This also affects the blood flow velocity patterns, which are markedly different from young to elderly. Thus, changes in blood flow patterns in the AA related to age and gender are observed. Further investigations are needed to determine the relation between changes in blood flow patterns and AAA development.

    This article uses data from the United States, Jamaica, Malaysia, and Bangladesh to explore gender differences in adult health. The results show that women fare worse than men across a variety of self-reported health measures in all four countries studies. These health status disparities between men and women persist even after appropriate corrections are made for the impact of (a) differential mortality selection by gender and (b) sociodemographic factors. Data from Jamaica indicate that gender disparities in adult health arise early and persist throughout the life cycle, with different age profiles for different measures. PMID:7959102

  6. Gender Differences in Cancer Susceptibility: An Inadequately Addressed Issue

    Dorak, M. Tevfik; Karpuzoglu, Ebru

    2012-01-01

    The gender difference in cancer susceptibility is one of the most consistent findings in cancer epidemiology. Hematologic malignancies are generally more common in males and this can be generalized to most other cancers. Similar gender differences in non-malignant diseases including autoimmunity, are attributed to hormonal or behavioral differences. Even in early childhood, however, where these differences would not apply, there are differences in cancer incidence between males and females. In childhood, few cancers are more common in females, but overall, males have higher susceptibility. In Hodgkin lymphoma, the gender ratio reverses toward adolescence. The pattern that autoimmune disorders are more common in females, but cancer and infections in males suggests that the known differences in immunity may be responsible for this dichotomy. Besides immune surveillance, genome surveillance mechanisms also differ in efficiency between males and females. Other obvious differences include hormonal ones and the number of X chromosomes. Some of the differences may even originate from exposures during prenatal development. This review will summarize well-documented examples of gender effect in cancer susceptibility, discuss methodological issues in exploration of gender differences, and present documented or speculated mechanisms. The gender differential in susceptibility can give important clues for the etiology of cancers and should be examined in all genetic and non-genetic association studies. PMID:23226157

    2014-08-12

    Cognitive gender differences and the reasons for their origins have fascinated researchers for decades. Using nationally representative data to investigate gender differences in cognitive performance in middle-aged and older populations across Europe, we show that the magnitude of these differences varies systematically across cognitive tasks, birth cohorts, and regions, but also that the living conditions and educational opportunities individuals are exposed to during their formative years are related to their later cognitive performance. Specifically, we demonstrate that improved living conditions and less gender-restricted educational opportunities are associated with increased gender differences favoring women in some cognitive functions (i.e., episodic memory) and decreases (i.e., numeracy) or elimination of differences in other cognitive abilities (i.e., category fluency). Our results suggest that these changes take place due to a general increase in women's cognitive performance over time, associated with societal improvements in living conditions and educational opportunities.

    Grouping students for labs in science classes is a common practice. This mixed methods quasi-experimental action research study examines homogeneous and heterogeneous gender grouping strategies to determine what gender grouping strategy is the most effective in a coeducational science classroom setting. Sixth grade students were grouped in same-gender and mixed-gender groups, alternating each quarter. Over the course of an academic year, data were collected from four sources. The teacher-researcher observed groups working during hands-on activities to collect data on student behaviors. Students completed post-lab questionnaires and an end-of-course questionnaire about their preferences and experiences in the different grouping strategies. Student scores on written lab assignments were also utilized. Data analysis focused on four areas: active engagement, student achievement, student perceptions of success and cooperative teamwork. Findings suggest that teachers may consider grouping students of different ability levels according to different gender grouping strategies to optimize learning.

    1999-06-01

    Information from pension providers was examined to investigate gender differences in pension wealth at midlife. For full-time wage and salary workers approaching retirement age who had pension coverage, median pension wealth on the current job was 76% greater for men than women. Differences in wages, years of job tenure, and industry between men and women accounted for most of the gender gap in pension wealth on the current job. Less than one third of the wealth difference could not be explained by gender differences in education, demographics, or job characteristics. The less-advantaged employment situation of working women currently in midlife carries over into worse retirement income prospects. However, the gender gap in pensions is likely to narrow in the future as married women's employment experiences increasingly resemble those of men. PMID:10396890

    Starting in adolescence and continuing through adulthood, women are twice as likely as men to experience depression. According to the response styles theory (RST), gender differences in depression result, in part, from women’s tendency to ruminate more than men. A meta-analysis was performed to evaluate gender differences in rumination in adults (k = 59; N = 14,321); additionally, an analysis of subtypes of rumination – brooding and reflection – was conducted (k = 23). Fixed effects analyses indicated that women scored higher than men in rumination (d = .24, p < .01, SEd = .02), brooding (d = .19, p < .01, SEd = .03) and reflection (d = .17, p < .01, SEd = .03); there was no evidence of heterogeneity or publication bias across studies for these effect sizes. Although statistically significant, the effect sizes for gender differences in rumination were small in magnitude. Results are discussed with respect to the RST and gender differences in depression.

    It is important to understand gender difference on pesticide use knowledge, attitude and practices for identifying pesticide risks by gender and to recommend more gender-sensitive programs. However, very few studies have been conducted so far in Nepal. This study, thus, interviewed a total of 325 males and 109 females during 2005 to assess gender differences on pesticide use knowledge, attitude and practices. More than 50% females had never been to school and only <8% individuals were found trained in Integrated Pest Management (IPM). Almost all males and females did not smoke, drink and eat during pesticides application and also believed that pesticides are harmful to human health, livestock, plant diversity and their environment. However, there were gender differences on household decision on pesticides to be used (p<0.001), care of wind direction during spraying (p=0.032), prior knowledge on safety measures (p=0.016), reading and understanding of pesticides labels (p<0.001), awareness of the labels (p<0.001) and protective covers. Almost all respondents were aware of negative impacts of pesticide use on human health and environment irrespective of gender; however, females were at higher risk due to lower level of pesticide use safety and awareness. It is strongly recommended to initiate gender-sensitive educational and awareness activities, especially on pesticide use practices and safety precautions.

  13. [The reign of hormones and the construction of gender differences].

    PubMed

    Rohden, Fabíola

    2008-06-01

    Within the context of the theoretical debate on gender and science, the article discusses the process of redefining gender and sex differences using so-called biological or natural markers. It identifies how gender differences undergo naturalization using a logic of 'substantialization or 'materialization'. This process is exemplified in how medicine views women, promoting explanatory models of economics of the female body that are at times centered around organs like the uterus and ovaries, at other times centered on the mechanics of hormones, and, most recently, focused on genetic and neurological differences. More specifically, it follows the discovery of so-called sex hormones and its relation to a dualist perspective of gender. These powerful chemical messengers helped shaped the passage from the logic of excess surrounding sex through the late nineteenth century, to the imperative of insufficiency, prevalent since the mid-twentieth century.

    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}{sup 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.

    The aims of this study were to estimate the difference in exercise intensity (METs), energy cost (EE) and gender difference between a typical salsa lesson (TSL), rueda de casino lesson (RCL), and salsa dancing at a night club (SDN). Subjects performed 1 pre-testing session and 3 testing conditions. During the pre-testing session height, weight and V˙O2max were assessed. During the testing conditions all subjects performed 3 different kinds of salsa dance. Heart rate was assessed during each dance condition. The exercise intensity of the 3 salsa dancing conditions was moderate ranging from 3.9 to 5.5 METs. A significant difference between genders for HRpeak (P=0.01), max%HRR (P=0.006) and mean EE (P=0.02) were observed. Significant gender×condition interactions for HRpeak (P=0.03), mean %HRR (P=0.02), mean METs (P=0.02) and mean EE (P=0.02) were found. In addition, a significant main effect for each condition was found in all variables (P<0.01). Our results showed that the exercise intensities of all 3 salsa dancing conditions were moderate. Findings showed some significant differences in exercise intensity between males and females and within conditions. Salsa dancing could be useful in achieving a significant training effect in people who have a low level of fitness. PMID:23041966

    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. (PsycINFO Database Record PMID:26348480

    Although gender is increasingly perceived as a key determinant in health and illness, systematic gender studies in medicine are still lacking. For a long time, cardiovascular disease (CVD) has been seen as a “male” disease, due to men's higher absolute risk compared with women, but the relative risk in women of CVD morbidity and mortality is actually higher: Current knowledge points to important gender differences in age of onset, symptom presentation, management, and outcome, as well as traditional and psychosocial risk factors. Compared with men, CVD risk in women is increased to a greater extent by some traditional factors (eg, diabetes, hypertension, hypercholesterolemia, obesity,) and socioeconomic and psychosocial factors also seem to have a higher impact on CVD in women. With respect la differences in CVD management, a gender bias in favor of men has to be taken into account, in spite of greater age and higher comorbidity in women, possibly contributing to a poorer outcome. Depression has been shown to be an independent risk factor and consequence of CVD; however, concerning gender differences, The results have been inconsistent. Current evidence suggests that depression causes a greater increase in CVD incidence in women, and that female CVD patients experience higher levels of depression than men. Gensier aspects should be more intensively considered, both in further research on gender differences in comorbid depresion, and in cardiac treatment and rehabilitation, with the goal of making secondary prevention more effective.

    We examined gender differences in appetite sensations when exposed to Mediterranean diet (MedDiet) meals and determined whether there are gender differences in the change in the satiating properties of the MedDiet over time. Thirty-eight men and 32 premenopausal women consumed a 4-week isoenergetic MedDiet under controlled conditions. Visual analogue scales were used to measure perceived appetite sensations before and immediately after each meal consumed over the course of one day (Wednesday) of the first and the fourth week of intervention. Women reported greater decreases for desire to eat, hunger, and appetite score than men in response to the consumption of the MedDiet meals (gender-by-meal interactions, resp., P = 0.04, P = 0.048, and P = 0.03). Fullness and prospective food consumption responses did not significantly differ between men and women. Between the first and the fourth week of intervention, premeal prospective food consumption increased with time in men (P = 0.0007) but not in women (P = 0.84; P for gender-by-time interaction = 0.04). These results indicate gender differences in appetite sensations when exposed to the MedDiet. These results may be useful in order to have a better understanding of gender issues for body weight management. PMID:26442158

    This paper uses a framework developed for gender and tropical diseases for the analysis of non-communicable diseases and conditions in developing and industrialized countries. The framework illustrates that gender interacts with the social, economic and biological determinants and consequences of tropical diseases to create different health outcomes for males and females. Whereas the framework was previously limited to developing countries where tropical infectious diseases are more prevalent, the present paper demonstrates that gender has an important effect on the determinants and consequences of health and illness in industrialized countries as well. This paper reviews a large number of studies on the interaction between gender and the determinants and consequences of chronic diseases and shows how these interactions result in different approaches to prevention, treatment, and coping with illness. Specific examples of chronic diseases are discussed in each section with respect to both developing and industrialized countries. PMID:17615903

    Gender differences among children and adolescents were examined on 14 separate measures of short-term memory. A nationally stratified sample of 1,279 children and adolescents, 637 males and 642 females, ranging in age between 5 and 19 years, were assessed on the 14 subtests of the Test of Memory and Learning (TOMAL). Factor structure of the TOMAL was determined to be invariant as a function of gender. Using age-corrected deviation scaled scores calculated at 1-year intervals, results of a one-way multivariate analysis of variance (MANOVA) revealed only two significant differences in absolute scores across gender on the 14 memory subtests. A profile of normal variations in patterns of memory test performance across gender revealing relative strengths for females on verbal tasks and males on spatial tasks is presented for clinical use and future normative comparisons.

    In the past 25 years, the number of female forensic psychiatrists has increased dramatically. To assess whether there are gender differences in the practice patterns of forensic psychiatry experts, members of the American Academy of Psychiatry and the Law were surveyed during an annual business meeting. Women in the sample were shown to perform fewer categories of evaluation than men. Women were less likely than men to do criminal work, civil commitment/involuntary medication evaluations, and testamentary capacity evaluations, but there was no significant difference in the percentage of those performing some personal injury/disability/fitness for duty, custody, sexual harassment, or malpractice evaluations. Gender was not a significant factor in determining hourly rate. When subjects were asked to comment on whether they thought that gender was a factor in the selection of a forensic expert, 80 percent of the women, but only 41 percent of the men, believed that gender was a consideration.

    Research shows that abuse in adolescence can start early and current literature regarding gender differences in Teen Relationship Violence (TRV) is inconsistent. Age and Gender differences in TRV were examined. Measures assessing TRV and its correlates were completed by 231 teens from 7th, 9th, and 11th grade classes. A 2 (gender) by 3 (grade) multivariate analysis of variance revealed significant effects for grade and gender indicating that 7th graders have lower perpetration and victimization of TRV, less anger control, and fewer positive conflict resolution behaviors than 9th and 11th graders. Furthermore, girls perpetrate more physical and emotional abuse while boys perpetrate more sexual abuse. Results have implications for timing and content of prevention programs addressing dating violence in adolescence. PMID:26989341

    Thirty physical science and 30 chemistry classes, which contained a total of 1332 students, were observed using the Brophy-Good Teacher-Child Dyadic Interaction System. Classroom interactions were examined for gender differences that may contribute to the underrepresentation of women in physics and engineering courses and subsequent careers. The Brophy-Good coding process allows for examination of patterns of interactions for individuals and groups of pupils. An analysis of variance of the data yielded a significant main effect for teacher praise, call outs, procedural questions, and behavioral warnings based on the sex of the student and a significant teacher-sex main effect for direct questions. Significant two-way interactions were found for the behavioral warning variable for teacher sex and subject by student sex. Female teachers warned male students significantly more than female students. Male teachers warned both genders with similar frequency. Male students also received significantly more behavioral warnings in physical science classes than female students. In chemistry classes, both male and female students received approximately the same number of behavioral warnings.

  6. Gender differences in ethical perceptions of business practices: a social role theory perspective.

    Franke, G R; Crown, D F; Spake, D F

    1997-12-01

    This study presents a meta-analysis of research on gender differences in perceptions of ethical decision making. Data from more than 20,000 respondents in 66 samples show that women are more likely than men to perceive specific hypothetical business practices as unethical. As suggested by social role theory (A. H. Eagly, 1987), the gender difference observed in precareer (student) samples declines as the work experience of samples increases. Social role theory also accounts for greater gender differences in nonmonetary issues than in monetary issues. T. M. Jones's (1991) issue-contingent model of moral intensity helps explain why gender differences vary across types of behavior. Contrary to expectations, differences are not influenced by the sex of the actor or the target of the behavior and do not depend on whether the behavior involves personal relationships or action vs. inaction.

    Background Limited research has been conducted on gender differences in perceived environmental correlates of physical activity (PA). The purpose of this study was to explore the potential role of gender in the link between perceived environment and PA. Methods Using a telephone-administered survey, data was collected on leisure time physical activity (LTPA), perceptions of the neighbourhood environment, and self-efficacy in a representative sample of 1209 adults from the province of Alberta, Canada. LTPA was regressed on ten measures of perceived neighbourhood environment and self-efficacy in a series of logistic regressions. Results Women were more likely than men to perceive their neighbourhood as unsafe to go for walks at night (χ2 = 67.46, p < 0.001) and to report seeing people being active in their neighbourhood (χ2 = 6.73, p < 0.01). Conversely, women were less likely to perceive easy access to places for PA (χ2 = 11.50, p < 0.01) and availability of places to buy things within easy walking distance from home (χ2 = 4.30, p < 0.05). Adjusting for age, education, income, and place of residence, access to places for PA (OR = 2.49) and interesting things to look at in the neighbourhood (OR = 1.94), were associated with higher levels of LTPA in men. Access to places for PA (OR = 2.63) and reporting seeing people being active (OR = 1.50) were associated with increased LTPA among women. After controlling for sociodemographic variables and self-efficacy, the presence of shops and places to buy things within easy walking distance from home (OR = 1.73), interesting things to look at in the neighbourhood (OR = 1.65), and access to places for PA (OR = 1.82) were associated with higher levels of LTPA in men. Among women, no significant relationships were observed between perceived environment and LTPA after adjusting for self-efficacy. Conclusion The results provide additional support for the use of models in which gender is treated as a potential moderator of the link between the perceived environment and PA. Further, the results suggest the possibility of differential interventions to increase PA based on factors associated with gender. PMID:16159404

  8. Gender differences in life expectancy among kibbutz members.

    1985-01-01

    A literature review of findings reveals that the life expectancy (LE) of females is longer than that of males and that a strong relationship exists between LE and gender differences in LE. The arguments of biological vs societal reasons for such gender differences are presented and the kibbutz society is offered as a setting to test the rivaling hypotheses. It is argued that the kibbutz society offers more similar roles for both genders than outside the kibbutz and therefore the gender differences in LE should be reduced in comparison to what is expected, given the very high LE of kibbutz members. Statistical data of the kibbutz population between the years 1975-1980 are analyzed and the results support the following conclusions: female members have higher LE but the difference is much less than expected on the basis of a regression analysis of data from 73 societies; the difference is smaller due to the relatively higher gain in LE by males; the gender differences are even smaller at age 50 compared to LE differences at birth. The Discussion section dwells upon interpretations of the findings and argues against alternative interpretations that assume selection processes for the kibbutz population. Suggestions for further studies are also made. PMID:4049023

  9. Revisiting Mars and Venus: understanding gender differences in critical illness

    PubMed Central

    2011-01-01

    Understanding the nature and biological basis of gender-determined differences in risk of and outcome from infection might identify new therapeutic targets, allow more individualised treatment, and facilitate better risk prediction and application of healthcare resources. Gender differences in behaviours, comorbidities, access to healthcare and biology may result in differences in acquiring infection, or in response to infection once acquired. Some studies have reported higher male susceptibility to infection, and higher risk of death with sepsis, but others have found the opposite effect. The explanation for this disagreement is probably that different studies have included patients at different stages on the continuum from infectious agent exposure to death or recovery. Studying sufficient patient numbers to explore this entire continuum while accounting for heterogeneity in type of infection and comorbidity is difficult because of the number of patients required. However, if true gender effects can be identified, examination of their biological or psychosocial causes will be warranted. PMID:21888682

    Milivojevich, Andrew

    2013-01-01

    The gender ratio among children in the autism spectrum of more than four boys to every girl is widely recognized. The authors present an analysis of gender differences among 79 482 symptoms and strengths in 1495 boys and 336 girls aged 2 to 18 years from parent-identified autistic children reported to a structurally novel anonymous parent-entered online database, Autism360. The data reveal differences that provide previously undetected clues to gender differences in immune and central nervous system and gastrointestinal functional disturbances. Together with published observations of male/female differences in inflammation, oxidative stress, and detoxication, these findings open doors to research focusing on gender physiology as clues to etiologic factors in autism. This study exemplifies a research method based on a large, detailed, patient-entered, structured data set in which patterns of individual illness and healing may answer collective questions about prevention and treatment.

  14. Differences in students' perceived classroom experiences by instructor gender, student gender, and persistence in STEM courses

    Fowlkes, Carol

    Science, technology, engineering, and mathematics (STEM) fields are growing and have lucrative job opportunities for college graduates. However, the number of students in STEM majors and the number of those who persist in those majors is declining; there is also a growing gender gap in STEM graduates. This study investigated three perceived classroom experiences in STEM courses and the nature of differences in these experiences by student gender, instructor gender, and by those who persisted or did not persist in STEM majors. A factorial MANOVA was the statistical method by which the differences were explored. The statistical analysis revealed non-significant mean differences in three-way interaction, all two-way interactions, and all main effects. There were not gendered differences in students' perceptions of the opportunities for hands-on learning, the instructor cares about students' success, and the instructor encourages students' contributions. Further research is proposed to continue examination of this topic with a larger data set that is consistent with the literature regarding the population of STEM students and the number of STEM persisters, and the male-gendered nature of STEM fields.

    1996-10-01

    An assertion was made that "There are no sex differences in Stroop interference" (MacLeod, 1991, p. 203) in spite of some evidence to the contrary (e.g., Sarmany, 1977). To resolve the discrepancy, this study examined the nature of gender differences in the context of other variables. 6 men and 8 women were tested, using response speed and errors made as dependent measures. Independent variables were gender, perceptual input (Stroop) task, congruency of stimuli, manual response output, and trial block. Contrary to MacLeod, men were consistently slower than women over trial blocks by some 46 msec., although their error rates did not differ significantly. Response output interacted with gender, with Stroop task, and with trial block. Congruent stimuli were processed faster than incongruent ones. Differences may be ascribed to greater verbal and fine motor abilities of women and greater spatial ability of men. PMID:8902031

    The emergence of cooperation among unrelated human subjects is a long-standing conundrum that has been amply studied both theoretically and experimentally. Within the question, a less explored issue relates to the gender dependence of cooperation, which can be traced back to Darwin, who stated that "women are less selfish but men are more competitive". Indeed, gender has been shown to be relevant in several game theoretical paradigms of social cooperativeness, including prisoner's dilemma, snowdrift and ultimatum/dictator games, but there is no consensus as to which gender is more cooperative. We here contribute to this literature by analyzing the role of gender in a repeated Prisoners' Dilemma played by Spanish high-school students in both a square lattice and a heterogeneous network. While the experiment was conducted to shed light on the influence of networks on the emergence of cooperation, we benefit from the availability of a large dataset of more 1200 participants. We applied different standard econometric techniques to this dataset, including Ordinary Least Squares and Linear Probability models including random effects. All our analyses indicate that being male is negatively associated with the level of cooperation, this association being statistically significant at standard levels. We also obtain a gender difference in the level of cooperation when we control for the unobserved heterogeneity of individuals, which indicates that the gender gap in cooperation favoring female students is present after netting out this effect from other socio-demographics factors not controlled for in the experiment, and from gender differences in risk, social and competitive preferences.

    2000-10-31

    We have investigated gender-related differences of bone mineral density and fracture threshold in 136 males (age, 60.7+/-9.3 years) and 337 females (age, 59.7+/-7.8 years) without evidence of secondary osteoporosis. Women and men were examined for total amount of spine fractures and bone mineral density by quantitative computed tomography (QCT) of three non-fractured vertebral bodies L1-L5. Females with lumbar fractures (n=96) when compared with non-fracture women (n=241) were older and had lower bone density at their vertebral sites. Males with vertebral fractures (n=52) were older and had a significantly reduced bone mineral density of the spine when compared with healthy males (n=84). When we compared gender-related vertebral fracture rates, we observed a significantly higher prevalence of vertebral fractures in the male population. After matching males and females for age and bone mineral density to exclude an influence of either variable, we compared the prevalence of vertebral fracture risk in both sexes with logistic regression analysis. Data of estimated fracture risk, differed very significantly for sex and bone density at the vertebral site, indicating that men present fracture at a higher bone density level compared with females; in 10% of study population fractures occurred at a QCT level of 105 mg/cm(3) in women and 120 mg/cm(3) in men. The estimated odds ratio for sex of 3.1 (95% CI) means a three-fold increased risk for vertebral fractures compared to males at a given density level. These results underline that a decreased bone mineral density leads to the occurrence of spine fractures in females and males as well. PMID:11063899

    The incidence of esophageal adenocarcinoma (EAC) has risen sharply in western countries over the past 4 decades. This type of cancer is considered to follow a transitional process that goes from gastro-esophageal reflux disease (GERD) to Barrett’s esophagus (BE, a metaplastic condition of the distal esophagus), a precursor lesion and ultimately adenocarcinoma. This spectrum of GERD is strongly predominant in males due to an unidentified mechanism. Several epidemiologic studies have described that the prevalence of GERD, BE and EAC in women is closely related to reproductive status, which suggests a possible association with the estrogen level. Recently, we revealed in an in vivo study that the inactivation of mast cells by the anti-inflammatory function of estrogen may account for the gender difference in the GERD spectrum. Other studies have described the contribution of female steroid hormones to the gender difference in these diseases. Estrogen is reported to modulate the metabolism of fat, and obesity is a main risk factor of GERDs. Moreover, estrogen could confer esophageal epithelial resistance to causative refluxate. These functions of estrogen might explain the approximately 20-year delay in the incidence of BE and the subsequent development of EAC in women compared to men, and this effect may be responsible for the male predominance. However, some observational studies demonstrated that hormone replacement therapy exerts controversial effects in GERD patients. Nevertheless, the estrogen-related endocrine milieu may prevent disease progression toward carcinogenesis in GERD patients. The development of innovative alternatives to conventional acid suppressors may become possible by clarifying the mechanisms of estrogen. PMID:26855539

    Drawing on social dominance theory and the contact hypothesis, we developed and tested a two-mediator model for explaining gender differences in early adolescents’ attitudes toward gay males and lesbians. Data from more than 400 ninth graders were analyzed. As predicted, gender differences in attitudes toward gay males were partially explained by social dominance orientation (SDO) and knowing a gay male. Gender differences in attitudes toward lesbians were partially mediated by SDO, while knowing a lesbian was not a mediating variable. Beyond their mediating roles, both SDO and knowing a member of the target group each significantly added to the prediction of attitudes toward each target group. Implications for policies to reduce victimization of sexual minorities in schools are discussed. PMID:20191095

    The purpose of this study was to determine whether there are dialectal and gender related differences in nasalance of main Mandarin vowels and three sentences in 400 Chinese normal adults. The mean nasalance score difference for dialect and gender was significant (p < .001) in all speech materials. For different dialects, the average nasalance scores show that Chongqing > Beijing > Shanghai > Guangzhou for the nasal sentence, oro-nasal sentence, /a/, /i/ and /u/. In addition, the average nasalance scores of females were higher than those of males for all speech materials in all dialects. The clinical significance of this study can be helpful in making nasalance clinical decisions for Chinese people with cleft palate, hearing disorders and dysarthria with resonance disorders. It also shows the theoretical and socio-cultural features for linguists considering dialects and gender. PMID:26853731

    Hopper, Ingrid; Kotecha, Dipak; Chin, Ken Lee; Mentz, Robert J; von Lueder, Thomas G

    2016-02-01

    Compared to men, women with heart failure (HF) are often older, smoke less, and have more preserved ejection fraction (EF) and hypertensive HF rather than HF of ischemic etiology. Gender-stratified outcomes on comorbidities data in HF are scarce. Women have traditionally been underrepresented in HF trials. Although data suggest that overall prognosis may be better in women, they experience lower quality of life with greater functional impairment from HF compared to men. Gender differences have been reported for comorbid diabetes, chronic obstructive pulmonary disease, renal dysfunction, anemia, and depression and may explain gender disparity in outcomes. However, possible confounding of comorbidities with known prognostic determinants in HF (such as EF) as well as gender differences in the utilization of medical therapies obscures interpretation. In this review, we will explore the evidence for gender differences in non-cardiovascular comorbidities in HF. Our findings may guide clinicians to individualize HF care, according to best practice, in the hope of improving prognosis for this chronic and debilitating condition. PMID:26829930

    2010-12-01

    In a review of 46 meta-analyses of gender differences, overhand throwing had the largest gender difference favoring boys (ES > 3.0). Expectations for gender-specific performances may be less pronounced in female Australian Aborigines, because historical accounts state they threw for defense and hunting. Overhand throwing velocities and kinematics were recorded in 30 female and male Aboriginal Australian children 6-10 years old. Results indicated the Aboriginal girls and boys were more similar in horizontal ball velocities than U.S. girls and boys. Throwing kinematics between girls and boys were also more similar in Australian Aborigines than U.S. children. Aboriginal girls threw with greater velocities than U.S., German, Japanese, and Thai girls, while the boys were similar across cultures. PMID:21268467

    Suicide is the second leading cause of death in youth globally; however, there is uncertainty about how best to intervene. Suicide rates are typically higher in males than females, while the converse is true for suicide attempts. We review this “gender paradox” in youth, and in particular, the age-dependency of these sex/gender differences and the developmental mechanisms that may explain them. Epidemiologic, genetic, neurodevelopmental and psychopathological research have identified suicidal behaviour risks arising from genetic vulnerabilities and sex/gender differences in early adverse environments, neurodevelopment, mental disorder and their complex interconnections. Further, evolving sex-/gender-defined social expectations and norms have been thought to influence suicide risk. In particular, how youth perceive and cope with threats and losses (including conforming to others’ or one’s own expectations of sex/gender identity) and adapt to pain (through substance use and help-seeking behaviours). Taken together, considering brain plasticity over the lifespan, these proposed antecedents to youth suicide highlight the importance of interventions that alter early environment(s) (e.g., childhood maltreatment) and/or one’s ability to adapt to them. Further, such interventions may have more enduring protective effects, for the individual and for future generations, if implemented in youth. PMID:25540727

  7. Gender-based performance differences in an introductory physics course

    NASA Astrophysics Data System (ADS)

    McKinnon, Mark Lee

    Cognitive research has indicated that the difference between males and females is negligible. Paradoxically, in traditionally-taught college level introductory physics courses, males have outperformed females. UC Davis' Physics 7A (the first class of a three-quarter Introduction to Physics sequence for Life-Science students), however, counters this trend since females perform similarly to males. The gender-based performance difference within the other two quarters (Physics 7B & 7C) of the radically restructured, active-learning physics sequence still echo the traditionally-taught courses. In one experiment, I modified the laboratory activity instructions of the Physics 7C course to encourage further group interaction. These modifications did not affect the gender-based performance difference. In a later experiment, I compared students' performance on different forms of assessment for certain physics concepts during the Physics 7C course. Over 500 students took weekly quizzes at different times. The students were given different quiz questions on the same topics. Several quiz questions seemed to favor males while others were more gender equitable. I highlighted comparisons between a few pairs of questions that assessed students' understanding of the same physical concept. Males tended to perform better in responding to questions that seemed to require spatial visualization. Questions that required greater understanding of the physical concept or scientific model were more gender neutral.

  11. Gender differences in aggression of borderline personality disorder.

    PubMed

    Mancke, Falk; Bertsch, Katja; Herpertz, Sabine C

    2015-01-01

    Aggression is a core feature of borderline personality disorder (BPD). Well-replicated results from the general population indicate that men engage in aggression more frequently than women. This article addresses the question of whether gender also influences aggression in BPD, and whether the neurobiological mechanisms underlying aggressive behavior differ between male and female BPD patients. Data show that most self-reports, interviews and behavioral tasks investigating samples of BPD patients do not find enhanced aggressiveness in male patients, suggesting that BPD attenuates rather than aggravates gender differences usually present in the general population. Neurobiological studies comparing BPD patients with gender-matched healthy controls, however, reveal a number of interesting gender differences: On the one hand, there are well-replicated findings of reduced amygdala and hippocampal gray matter volumes in female BPD patients, while these findings are not shared by male patients with BPD. On the other hand, only male BPD patients exhibit reduced gray matter volume of the anterior cingulate cortex, increased gray matter volume of the putamen, reduced striatal activity during an aggression task, and a more pronounced deficit in central serotonergic responsivity. These neurobiological findings point to a particular importance of impulsivity for the aggression of male BPD patients. Limitations include the need to control for confounding influences of comorbidities, particularly as male BPD patients have been consistently found to show higher percentages of aggression-predisposing comorbid disorders, such as antisocial personality disorder, than female BPD patients. In the future, studies which include systematic comparisons between females and males are warranted in order to disentangle gender differences in aggression of BPD patients with the aim of establishing gender-sensitive treatments where needed.

    2008-01-01

    We used longitudinal mortality data sets for the 1990s to compare socioeconomic inequalities in total cancer mortality between women and men aged 30–74 in 12 different European populations (Madrid, Basque region, Barcelona, Slovenia, Turin, Switzerland, France, Belgium, Denmark, Norway, Sweden, Finland) and to investigate which cancer sites explain the differences found. We measured socioeconomic status using educational level and computed relative indices of inequality (RII). We observed large variations within Europe for educational differences in total cancer mortality among men and women. Three patterns were observed: Denmark, Norway and Sweden (significant RII around 1.3–1.4 among both men and women); France, Switzerland, Belgium and Finland (significant RII around 1.7–1.8 among men and around 1.2 among women); Spanish populations, Slovenia and Turin (significant RII from 1.29 to 1.88 among men; no differences among women except in the Basque region, where RII is significantly lower than 1). Lung, upper aerodigestive tract and breast cancers explained most of the variations between gender and populations in the magnitude of inequalities in total cancer mortality. Given time trends in cancer mortality, the gap in the magnitude of socioeconomic inequalities in cancer mortality between gender and between European populations will probably decrease in the future.

  13. Gender differences in the disposition and toxicity of metals

    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 recent 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.

    Reports of gender differences amongst arsonists at psychiatric assessment are not uncommon, however some are based on relatively small samples. A new retrospective study highlighting gender differences could help to confirm or refute the current state of knowledge. The aim of the current study was to examine gender differences amongst a sample of 167 adult arsonists (129 males and 38 females). Information was collected from clinical records on sociodemographic, family background and childhood factors; adult adjustment; fire setting history; motives; features of pyromania and other offending, from the case notes of a group of arsonists referred to the West Midlands Psychiatry Service over a 24-year period. Female arsonists were older than males and more likely to have a psychiatric diagnosis. Women more frequently had a history of sexual abuse, while men had a more varied criminal background and more substance abuse problems. Our findings largely support previous research, and are discussed in this context, whilst also bringing attention to a more recently developed theory (Action System Model). Significant gender differences amongst arsonists indicates that different emphases in the treatment of male and female arsonists may be advisable, though a reliable evidence base for treatment has yet to be established.

    The aim of this study was to evaluate possible gender differences in match play activity pattern [rally duration, rest time between rallies, effective playing time, and strokes performed during a rally] and exercise intensity (heart rate [HR], blood lactate [La], and subjective ratings of perceived exertion [RPE]) during 9 simulated badminton matches in male (n = 8) and female (n = 8) elite junior (16.0 1.4 years) players. Results showed significant differences (all p < 0.05; effect size (ES) = 0.80-1.56) between male and female players in the activity pattern of match play, with male players engaged in longer rallies (6.8 4.8 vs. 5.7 3.1 seconds), executing more strokes per rally (6.4 4.8 vs. 4.7 2.8) and resting more between rallies (10.5 8.8 vs. 8.8 7.2 seconds) than female players. No clear differences (all p > 0.05; ES = -0.33 to 0.08) were observed between female or male players in average HR (174 7 vs. 170 9 bmin(-1)), %HRmax (89.2 4.0% vs. 85.9 4.3%), La (2.5 1.3 vs. 3.2 1.8 mmolL(-1)), and RPE values (14.2 1.9 vs. 14.6 1.8) during match play, although male players spent more time (moderate effect sizes) at intensities between 81 and 90% HRmax (35.3 17.9 vs. 25.3 13.6; p < 0.05; ES = 0.64) in the second game. There seemed to be a trend toward an increased playing intensity (i.e., higher HR, La, and RPE) from the first to the second game, highlighting the higher exercise intensity experienced during the last part of the match. The clear between-gender differences in activity patterns induced only slightly different physiological responses. PMID:23238094

  18. Gender Differences in Academic Achievement: Is Writing an Exception to the Gender Similarities Hypothesis?

    2015-01-01

    The gender similarities hypothesis by J. S. Hyde ( 2005 ), based on large-scale reviews of studies, concludes that boys and girls are more alike than different on most psychological variables, including academic skills such as reading and math (J. S. Hyde, 2005 ). Writing is an academic skill that may be an exception. The authors investigated gender differences in academic achievement using a large, nationally stratified sample of children and adolescents ranging from ages 7-19 years (N = 2,027). Achievement data were from the conormed sample for the Kaufman intelligence and achievement tests. Multiple-indicator, multiple-cause, and multigroup mean and covariance structure models were used to test for mean differences. Girls had higher latent reading ability and higher scores on a test of math computation, but the effect sizes were consistent with the gender similarities hypothesis. Conversely, girls scored higher on spelling and written expression, with effect sizes inconsistent with the gender similarities hypothesis. The findings remained the same after controlling for cognitive ability. Girls outperform boys on tasks of writing. PMID:26135387

    In this paper, we model gender differences in cognitive ability in China using a new sample of middle-aged and older Chinese respondents. Modeled after the American Health and Retirement Study (HRS), the CHARLS Pilot survey respondents are 45 years and older in two quite distinct provinces—Zhejiang, a high-growth industrialized province on the East Coast, and Gansu, a largely agricultural and poor province in the West—in a sense new and old China. Our cognition measures proxy for two different dimensions of adult cognition—episodic memory and intact mental status. On both measures, Chinese women score much lower than do Chinese men, a gender difference that grows among older Chinese cohorts. We relate both these cognition scores to schooling, urban residence, family and community levels of economic resources, and height. We find that cognition is more closely related to mean community resources than to family resources, especially for women, suggesting that in traditional poor Chinese communities there are strong economic incentives to favor boys at the expense of girls. We also find that these gender differences in cognitive ability have been steadily decreasing across birth cohorts as the economy of China grew rapidly. Among cohorts of young adults in China, there is no longer any gender disparity in cognitive ability. This parallels the situation in the United States where cognition scores of adult women actually exceed those of adult men. PMID:24347682

    Wilansky-Traynor, Pamela; Lobel, Thalma E

    2008-08-01

    The present study examined the differential effect of an adult observer's presence on the sex-typed play behavior of gender schematic and aschematic preschoolers. A total of 116 Israeli preschoolers (M age = 64.9 months) participated in the study. Children were classified as either gender schematic or aschematic based upon responses to a computerized measure of different sex stereotype components. Children's play behavior with gender typical and atypical, attractive and unattractive, toys was videotaped. An observer was present for half the children's play and absent for the other half's play. Observation status affected the aschematic, but not the schematic, children's play with gender typical toys. For example, observed aschematic boys spent a greater percent of time playing with the unattractive masculine toys compared to unobserved aschematic boys. This difference was not apparent for schematic boys. Additionally, a difference found for schematic boys was not apparent in schematic girls, i.e., when unobserved, schematic boys tended to spend a greater percent of time playing with the unattractive masculine toy than aschematic boys. Further, some differences were found for unattractive, and not attractive, toys. For instance, observed aschematic boys spent a greater percent of time playing with the unattractive masculine toy than did the unobserved aschematic boys. This gap was not found for the attractive masculine toy. Results are discussed with reference to the accessibility and complexity of gender schemas. PMID:18299975

    2015-01-01

    The first efforts to uncover the causes of cardiovascular disease focused on the behavioral, now called lifestyle habits of populations. Diet, exercise, and smoking were recognized as important issues with strong relationships in community-based observational studies such as the Seven Countries study, the Framingham Heart Study, and the Western Electric Study in Chicago. The first meaningful intervention in the United States was the dietary recommendations made by the American Heart Association in 1963 and the Surgeon General's Report on Smoking and Health in 1964. The American public listened and a very large change occurred in food consumption data and cigarette smoking over the next decade. These changes were mainly focused on men because the incidence of myocardial infarction was much higher in middle aged and older men than women. As smoking prevalence has decreased in men and increased in women and the population has aged, the differences in major vascular events have virtually disappeared. Women still enjoy a longer period of low rates but eventually the incidence rates approach those of men. As we constantly attempt to demonstrate ways of reducing risk by improved lifestyle it behooves us to re-evaluate the potential differences in gender response and adjust our expectations accordingly as clinicians.

  4. Gender Related Differences in Kidney Injury Induced by Mercury

    PubMed Central

    Hazelhoff, Mara H.; Bulacio, Romina P.; Torres, Adriana M.

    2012-01-01

    The aim of this study was to determine if there are sex-related differences in the acute kidney injury induced by HgCl2 since female rats express lower levels of renal Oat1 and Oat3 (transporters involved in renal uptake of mercury) as compared with males. Control males and females and Hg-treated male and female Wistar rats were employed. Animals were treated with HgCl2 (4 mg/kg body weight (b.w.), intraperitoneal (i.p.)) 18 h before the experiments. HgCl2 induced renal impairment both in male and female rats. However, female rats showed a lower renal impairment than male rats. The observed increase in kidney weight/body weight ratio seen in male and female rats following HgCl2 treatment was less in the female rats. Urine volume and creatinine clearance decreased and Oat5 urinary excretion increased in both males and females, but to a lesser degree in the latter. Urinary alkaline phosphatase (AP) activity and histological parameters were modified in male but not in female rats after HgCl2 administration. These results indicate that the lower Oat1 and Oat3 expression in the kidney of females restricts Hg uptake into renal cells protecting them from this metal toxicity. These gender differences in renal injury induced by mercury are striking and also indicate that Oat1 and Oat3 are among the main transporters responsible for HgCl2-induced renal injury.

    The Spontaneously Diabetic Torii Lepr(fa) (SDT fatty) rat is a novel type 2 diabetic model wherein both male and female rats develop glucose and lipid abnormalities from a young age. In this study, we investigated gender differences in abnormalities and related complications in SDT fatty rats. Food intake was higher in males compared to female rats; however, body weight was not different between genders. Progression of diabetes, including increases in blood glucose and declines in blood insulin, was observed earlier in male rats than in females, and diabetic grade was more critical in male rats. Blood lipids tended to increase in female rats. Gonadal dysfunction was observed in both male and female rats with aging. Microangiopathies, such as nephropathy, retinopathy, neuropathy, and osteoporosis, were seen in both genders, and pathological grade and progression were more significant in males. Qualitative and quantitative changes were observed for metabolic disease gender differences in SDT fatty rats. The SDT fatty rat is a useful model for researching gender differences in metabolic disorders and related diseases in diabetes with obesity. PMID:24892034

    Objective This study examined gender differences in smoking and quitting among individuals diagnosed with schizophrenia in Korea. In addition, the study investigated differences in caffeine use by gender and smoking status. Method An anonymous self-report survey was conducted with psychiatric inpatients. Results Compared to males, females were less likely to be current smokers (p < 0.001) and more likely to be former smokers (p < 0.01). Females were also less likely to be daily caffeine users (p < 0.001). Having more years of education (p < 0.05) and higher nicotine dependence scores (p < 0.05) were associated with decreased odds of intending to quit smoking, whereas having more previous quit attempts (p < 0.01) was associated with increased odds. These findings were significant even after adjusting for gender. Smokers were more likely to be daily caffeine users (p < 0.001) than their non-smoking counterparts. Conclusion Nurses in Korea should play an active role in tobacco control for patients with schizophrenia by providing cessation counseling and educating the effect of caffeine use on cigarette consumption, while tailoring the service to gender differences found in this study.

    A gender discrepancy exists in the incidence of both urothelial and kidney carcinomas, with more men presenting with these cancers than women. Men have a threefold greater risk of developing bladder cancer than women, but female gender has been identified as an independent adverse prognostic factor for both recurrence and progression of this disease. In particular, women with bladder cancer are often diagnosed with a higher tumour stage than men. Conclusive data on the influence of gender on outcomes of patients with upper tract urothelial carcinoma are currently lacking, although men seem to have a higher disease incidence, whereas survival outcomes might be independent of gender. Patients with renal cell carcinoma are more often men and they typically have larger tumours and higher stage and grade disease than women with this cancer. Smoking habits, tumour biology, occupational risk factors and sex steroid hormones and their receptors could have a role in these observed gender disparities. The majority of data support the theory that gender influences incidence and prognosis of urothelial and kidney cancers; men and women are different genetically and socially, making the consideration of gender a key factor in the clinical decision-making process. Thus, the inclusion of this variable in validated prognostic tables and nomograms should be discussed as a matter of importance. PMID:26436686

    Background Individuals with cancer and their partners often experience communication difficulties. However, questions still remain regarding the influence of gender and role in cancer survivor-partner communication within couples. Objective The current study intended to examine the communication patterns in breast, colorectal, and prostate cancer survivor-partner couples during cancer survivorship and whether gender and role differences in couples communication exist. Methods The dominant-less dominant methods of sequential mixed design was utilized. Ten couples who were recruited from the University Hospital registry in Cleveland, Ohio participated in both mail surveys and individual interviews. Family and cancer-related communication was assessed in the quantitative phase. Results Both male survivors and partners demonstrated better family communication scores compared to their female counterparts, whereas there were no gender differences in the cancer-related communication scores. In the qualitative phase, 3 major themes were identified: 1) selective sharing of cancer-related issues, 2) initiation of cancer-related communication, and 3) emotional reaction in communication. The patterns associated with these themes differed between the male survivor-female partner and female survivor-male partner couples. Conclusions This study provides new knowledge about family and cancer-related communication. Our findings highlight the importance of understanding different perspectives in the quality of communication by gender and role. Implications for Practice Exploring couples' communication patterns by gender and role stimulates the research and the development of effective consumer-centered communication interventions. The findings provide assessment tools to inform dyadic communication patterns for clinical and scientific purposes. PMID:25122132

    Facial appearance can motivate behaviour and elicit activation of brain circuits putatively involved in reward. Gender differences have been observed for motivation to view beauty in adult faces--heterosexual women are motivated by beauty in general, while heterosexual men are motivated to view opposite-sex beauty alone. Although gender differences have been observed in sensitivity to infant cuteness, infant faces appear to hold equal incentive salience among men and women. In the present study, we investigated the incentive salience of attractiveness and cuteness in adult and infant faces, respectively. We predicted that, given alternative viewing options, gender differences would emerge for motivation to view infant faces. Heterosexual participants completed a "pay-per-view" key-press task, which allowed them to control stimulus duration. Gender differences were found such that infants held greater incentive salience among women, although both sexes differentiated infant faces based on cuteness. Among adult faces, men exerted more effort than women to view opposite-sex faces. These findings suggest that, contrary to previous reports, gender differences do exist in the incentive salience of infant faces as well as opposite-sex faces. PMID:22928658

    Development during life-span implies to cope with stressful events, and this coping may be done with several strategies. It could be useful to know if these coping strategies differ as a consequence of personal characteristics. This work uses the Coping with Stress Questionnaire with this aim using a sample of 400 participants. Specifically, the effects of gender and age group (young people, middle age and elderly), as well as its interaction on coping strategies is studied. With regard to age, on one hand, it is hypothesised a decrement in the use of coping strategies centred in problem solving and social support seeking as age increases. On the other hand, the use of emotional coping is hypothesised to increase with age. With respect to gender, it is hypothesised a larger use of emotional coping and social support seeking within women, and a larger use of problem solving within men. A MANOVA found significant effects for the two main effects (gender and age) as well as several interactions. Separate ANOVAs allowed us to test for potential differences in each of the coping strategies measured in the CAE. These results partially supported the hypotheses. Results are discussed in relation to scientific literature on coping, age and gender. PMID:23156917

  12. Gender Differences of Thromboembolic Events in Atrial Fibrillation.

    Atrial fibrillation (AF) is the most common clinically relevant arrhythmia and increases the risk of thromboembolism and stroke; however, these risks are not the same for women and men. This review examines the evidence and clinical significance of increased thromboembolic risk in women with AF. The balance of results from over 30 recent studies suggests that female gender is an independent stroke risk factor in AF, and the inclusion of female gender in stroke risk stratification models, such as CHA2DS2-VASc, has improved risk assessment. Reasons for the increased thrombogenicity in women remain incompletely elucidated, but biological factors including increased hypertension, renal dysfunction, and hyperthyroidism in female patients with AF; cardiovascular remodeling; increased hypercoagulability, and estrogen hormone replacement therapy in women have been proposed. More importantly, gender differences exist in medical management of patients with AF, and compared with men, women have been found to have greater thromboembolic risk when not on anticoagulants, but may benefit from greater risk reduction when systemically anticoagulated. In conclusion, increased clinician awareness of these gender differences may help to improve the management of patients with AF. PMID:26923085

    Magnetic resonance imaging (MRI) provides objective and detailed insights into morphologic changes of the central nervous system associated with multiple sclerosis (MS). Therefore, it also appears an ideal tool to investigate the possible impact of gender on MS course and severity. Only more recently some studies have specifically addressed this issue and we, therefore, reviewed the literature for investigations which analysed the impact of various factors including gender on MS-related morphologic changes and their evolution. Treatment trials were excluded and the available data refer mainly to relapsing MS with or without secondary progression. A few mostly smaller studies suggest a higher frequency of contrast-enhancing lesions in women. This was not seen in the analysis of a large and pooled dataset of untreated MS patients of the Sylvia Lawry Centre for MS Research. Other large cross-sectional and longitudinal studies found no effects of gender on T2 or T1 lesion burden or on brain atrophy. Findings between male and female MS patients also did not differ when including magnetisation transfer ratio and diffusion tensor imaging for morphologic information. Our review thus indicates no independent gender differences on brain MRI beyond demographic and clinical variables such as age, duration of disease and grade of disability. PMID:19709673

    The present study addresses the association between immigration from the former Soviet Union (FSU) and gender and alcohol consumption among a representative sample of young adults in Israel 2000. Previous studies that were conducted on FSU immigrants to Israel indicate higher consumption than that of resident Israelis and immigrants of earlier periods. The current study aims to assess alcohol consumption among FSU and resident Israelis five years later to determine whether the discrepancy in alcohol consumption stays consistent or reduces. In addition, gender differences in alcohol consumption among the Israeli society were examined as well, as a special case of socio-culture differences. The data came from the 2000 national survey of drinking in Israel. Of 5,004 Jewish Israelis, 532 were immigrants from the FSU who arrived since 1989, and 4,472 were resident Israelis. The FSU group was compared with resident Israelis, and males were compared to females on several drinking variables. Logistic regression was the principal method of analysis. Demographics and cultural variables as main effects or in interaction with FSU and gender were controlled. The FSU group was significantly more likely to report drinking in the last twelve months plus drinking in the last thirty days than resident Israelis. Women's reported drinking in the last twelve months was one fourth of men's and during the past thirty days was one fifth of men's. Further investigation on the associations between the success of FSU acculturation in the Israeli society and drinking patterns as well as attitudes toward women and gender differences in alcohol consumption may provide explanations for gender and immigration gaps in alcohol consumption.

    OBJECTIVE To estimate whether there is a gender difference in scholarly productivity among academic gynecologic oncologists. METHODS In this cross-sectional study, the academic rank and gender of gynecologic oncology faculty in the United States were determined from online residency and fellowship directories and departmental web sites. Each individual’s h-index and years of publication were determined from Scopus (a citation database of peer-reviewed literature). The h-index is a quantification of an author’s scholarly productivity that combines the number of publications with the number of times the publications have been cited. We generated descriptive statistics and compared rank, gender, and productivity scores. RESULTS Five hundred seven academic faculty within 137 U.S. teaching programs were identified. Of these, 215 (42%) were female and 292 (58%) were male. Men had significantly higher median h-indices than women, 16 compared with 8, respectively (P<.001). Women were more likely to be of junior academic rank with 63% of assistant professors being female compared with 20% of full professors. When stratifying h-indices by gender and academic rank, men had significantly higher h-indices at the assistant professor level (7 compared with 5, P<.001); however, this difference disappeared at the higher ranks. Stratifying by the years of active publication, there was no significant difference between genders. CONCLUSION Female gynecologic oncologists at the assistant professor level had lower scholarly productivity than men; however, at higher academic ranks, they equaled their male counterparts. Women were more junior in rank, had published for fewer years, and were underrepresented in leadership positions. PMID:26551177

    Stroke has a greater effect on women than men owing to the fact that women have more stroke events and are less likely to recover. Age-specific stroke rates are higher in men; however, because of women's longer life expectancy and the much higher incidence of stroke at older ages, women have more stroke events than men overall. The aims of this prospective study in consecutive patients were to assess whether there are gender differences in stroke risk factors, treatment or outcome. Consecutive patients with ischemic stroke were included in this prospective study at four study centers. Disability was assessed using a modified Rankin Scale score (>or=3 indicating disabling stroke) in both genders at 90 days. Outcomes and risk factors in both genders were compared using the chi(2) test. Multiple logistic regression analysis was used to identify any independent predictors of outcome. A total of 1136 patients were included in this study; of these, 494 (46%) were female. Women were statistically older compared with men: 76.02 (+/- 12.93) and 72.68 (+/- 13.27) median years of age, respectively. At admission, females had higher NIH Stroke Scale scores compared with males (9.4 [+/- 6.94] vs 7.6 [+/- 6.28] for men; p = 0.0018). Furthermore, females tended to have more cardioembolic strokes (153 [30%] vs 147 [23%] for men; p = 0.004). Males had lacunar and atherosclerotic strokes more often (146 [29%] vs 249 [39%] for men; p = 0.002, and 68 [13%] vs 123 [19%] for men; p = 0.01, respectively). The mean modified Rankin Scale score at 3 months was also significantly different between genders, at 2.5 (+/- 2.05) for women and 2.1 (+/- 2.02) for men (p = 0.003). However, at multivariate analysis, female gender was not an indicator for negative outcome. It was concluded that female gender was not an independent factor for negative outcome. In addition, both genders demonstrated different stroke pathophysiologies. These findings should be taken into account when diagnostic workup and treatment are being planned. PMID:20088729

    Risk factors, suicidal behavior, and help-seeking patterns differ between young women and men. We constructed a generic conceptual model of the processes underlying youth suicide, grounded in 78 interviews with parents in 52 consecutive cases of suicide (19 women, 33 men) identified at forensic medical autopsy and compared by sex. We found different forms of shame hidden behind gender-specific masks, as well as gender differences in their paths to suicide. Several interacting factors formed negative feedback loops. Finding no way out, the young persons looked for an "emergency exit." Signs and preparations could be observed at different times but recognized only in retrospect. Typically, the young persons and their parents asked for professional help but did not receive the help they needed. We discuss parents' experiences from the theoretical perspective on gender identity and developmental breakdown. Giving voice to the parents' tacit knowledge can contribute to better prevention and treatment. PMID:25810465

    The Project Access study examined the careers of men and women who had received prestigious postdoctoral fellowships and thus were presumably of about equal promise at the start of their professional careers. Had the women scientists in this elite group overcome a threshold beyond which they proceeded on equal footing with their male counterparts; or did a glass ceiling impede their careers? We found gender differences in career outcomes in the group we studied (699 questionnaires, 200 interviews), but these differences varied considerably by scientific discipline. Moreover, the career disparities for women, as a group, appear now to result chiefly from a series of subtle but identifiable and sometimes counterintuitive impediments as well as from slight gender differences in socialization. Each disadvantage by itself may be small, but in their accumulation they significantly influence women's careers.

    Despite the increased participation of girls in competitive high school athletics, it is unclear that play on sports teams holds the same meaning for adolescent boys and girls. This study investigated school, grade, (freshman and sophomore vs junior and senior), and gender differences associated with a range of factors related to participation in high school varsity soccer play among 65 students attending two high schools, one emphasizing achievement, the other emphasizing competitive involvement in athletics, including soccer. Also of interest was the relationship between both soccer involvement and soccer knowledge and school climate, empathy, occupational interest, and perceived parent behavior. Because gender differences were found in comparative and correlational analysis, it is concluded that play on varsity soccer teams holds different meanings and values for adolescent boys and girls.

    Predictive animal models of intestinal drug absorption are essential tools in drug development to identify compounds with promising biopharmaceutical properties. In situ perfusion absorption studies are routinely used in the preclinical setting to screen drug candidates. The objective of this work is to explore the differences in magnitude and variability on intestinal absorption associated with rat strain and gender. Metoprolol and Verapamil absorption rate coefficients were determined using the in situ closed loop perfusion model in four strains of rats and in both genders. Strains used were Sprague-Dawley, Wistar-Han, Wistar-Unilever, Long-Evans and CD?IGS. In the case of Metoprolol only CD?IGS and Wistar Unilever showed differences between males and females. For Verapamil, Wistar Han and Sprague-Dawley strains do not show differences between male and female rats. That means that in these strains permeability data from male and female could be combined. In male rats, which are commonly used for permeability estimation, there were differences for Metoprolol permeability between Sprague-Dawley (with lower permeability values) and the other strains, while for Verapamil Sprague-Dawley and Wistar-Han showed the lower permeability values. In conclusion, the selection of rat's strain and gender for intestinal absorption experiments is a relevant element during study design and data from different strains may not be always comparable.

    Gender differences in pathological gambling disorder (PGD) have received little investigation. This study was constructed to detail the demographic and phenomenological differences in men and women with PGD. We assessed gender differences in 131 subjects with PGD who were evaluated in terms of demographic characteristics, clinical features of PGD, and treatment history. Seventy-eight (60%) subjects were women, and 53 (40%) were men. Men had an earlier age of onset of gambling behavior, while women progressed to pathological gambling sooner after beginning to gamble. In terms of gambling behavior, men were more likely to engage in blackjack, cards, sporting events, and the track, whereas women played slot machines and bingo. Women reported that loneliness was the major trigger to gambling, while men were more likely to gamble secondary to sensory stimuli. Although men were as likely as women to have filed bankruptcy because of gambling, women were more likely to have written bad checks and men were more likely to have lost significant savings. Both groups were equally likely to seek treatment, but Gamblers Anonymous (GA) and outpatient therapy were reported equally ineffective in reducing gambling symptoms. There appear to be some gender differences in the clinical features of PGD, and these differences may have treatment implications. PMID:11788920

    Objective Internationally, increasing numbers of women are practising medicine. Gender differences in doctors’ working hours, specialty choices and communication styles are well documented, but studies often neglect contextual factors such as the role of socialised gender expectations on behaviours in the workplace and the medical profession. These may be important as recent studies have reported gender differences in doctors’ activity rates that cannot be explained by specialty or contracted hours, suggesting other sources of variation. This study sought to explore the working lives of hospital doctors and how their work is negotiated according to gender and context. Design Gender differences in the day-to-day work of hospital specialists (consultants) in the NHS were investigated using a qualitative approach, including observation and interview methods. Data were analysed inductively using qualitative observation and interview methods. Setting Two NHS hospital trusts in England. Participants Data were collected from 13 participants working in a variety of specialties and in a range of clinical and non-clinical settings. Main outcome measures Various behaviours, attitudes and experiences were explored, such as doctor–patient communication, interactions with colleagues and workload. Results Influences at both individual and situational levels, appear to affect differentially the work of male and female doctors. Female consultants described awareness of the impact of behaviours on relationships with colleagues, and their interactions appeared to be more carefully performed. Nurses and other colleagues tend to demonstrate less cooperation with female consultants. Gender differences also exist in patient communication, feelings of work–family conflict and barriers to career progression. Conclusions These variations in hospital consultants’ work may have implications for both the quantity and quality of care provided by male and female consultants. This is timely and of importance to the medical workforce as the gender composition approaches parity. PMID:25567767

    Clinical analyses have shown that injuries and pain linked specifically to fencing training/competition were prevalent in 92.8% of fencers. Patellofemoral pain is the most common chronic injury in athletic populations and females are considered to be more susceptible to this pathology. This study aimed to examine gender differences in patellofemoral contact forces during the fencing lunge. Patellofemoral contact forces were obtained from eight male and eight female club level epee fencers using an eight-camera 3D motion capture system and force platform data as they completed simulated lunges. Independent t-tests were performed on the data to determine whether gender differences in patellofemoral contact forces were present. The results show that females were associated with significantly greater patellofemoral contact force parameters in comparison with males. This suggests that female fencers may be at greater risk from patellofemoral pathology as a function of fencing training/competition. PMID:25630246

    More than half of the 1.6 million adults in U.S. prions are parents. Despite growing knowledge regarding the life course adversities of corrections-involved populations, less is known regarding incarcerated parents per se and the implications of cumulative adversities both on their needs and those of their children. Using a gender-balanced (41% minority) sample of incarcerated parents (N=357) from a randomized controlled trial of an in-prison parent training program, this study examines differences between incarcerated mothers and fathers in their exposures to adversities across the life course. Mothers and fathers shared similar patterns of adversity exposure in their families of origin, but differed in their experiences of juvenile justice and child welfare systems involvement, as well as in their adult experiences of victimization and related adult social and mental health outcomes. Implications for gender-responsive parent support and prevention programs for their children of incarcerated mothers and fathers are discussed. PMID:26998189

    2014-01-01

    Background This study examined gender differences in healthy life expectancy (HLE) and unhealthy life expectancy (UHLE) among people aged 60 years or older living in a large Brazilian city. Methods Based on Chiang method, abridged life tables were constructed for men and for women. To calculate HLE, the Sullivan method was applied. Estimates of the prevalence of self-rated health and self-reported functional disability (global, mild/moderate, and severe) were obtained from a population-based household survey carried out in 2008, which involved non-institutionalized individuals. Results Findings showed that women live longer and these extra years would be spent in good self-rated health. For example, women aged 60 would live, on average, 4 more years in good health in comparison to men. In terms of global limitations and mild/moderate limitations, no gender differences were detected for HLE. However, UHLE was statistically higher among women than among men at all ages in the global limitations and mild/moderate limitations (except for the age 80). Women at age 60, for instance, could expect to live 3.1 years longer with mild/moderate limitations compared to men. Gender differences were identified for severe limitations for either HLE or UHLE. In comparison to men, women at age 60, for example, would expect to live 2.5 and 2.0 more years without and with severe limitations. Conclusions By showing that the advantage of longer life expectancy among women is not necessarily accompanied by worse health conditions, these findings add some evidence to the debate about male-female health-survival paradox. Policy efforts are necessary to reduce gender differences in the quantity and quality of years to be lived, providing equal opportunities to women and men live longer with quality of life, autonomy, and independence.

    This study examined whether rural adolescents would report gender and ethnic differences in body image similar to those that have been observed in urban samples. Data were analyzed for 384 rural adolescents (57% African American, 43% Caucasian, mean age 13 years) to determine gender and ethnic differences in body dissatisfaction, body size discrepancy, and current and ideal figure ratings. Females wanted to be smaller and reported more body dissatisfaction than did males. Caucasian females reported the most body dissatisfaction. African Americans reported larger current and ideal figure ratings than did Caucasians. African Americans preferred larger opposite sex figures than did Caucasians. Both African American and Caucasian males selected a larger female figure as ideal than was selected by females. Results demonstrated that gender and ethnic differences exist in body image for rural adolescents. This frequently overlooked population may benefit from further study. Implications of findings and limitations of the study are also discussed. PMID:18089257

    The present study investigated chemosensory gender differences by means of ratings of total nasal chemosensory intensity, unpleasantness and sensory irritation and simultaneous recordings of chemosensory event-related potentials (CSERPs) for three concentrations of the olfactory/trigeminal stimulus pyridine in 19 women and 17 men, all young adults. Results show that, compared to men, women gave higher intensity and unpleasantness ratings, in particular for the highest stimulus concentration. The gender differences in perceived intensity are reflected in the signal-to-noise ratio of the individual CSERP averages, revealing more identifiable early components (P1, N1) in women than in men. The late positive component, labeled P2/P3, displayed larger amplitudes at all electrode sites and shorter latencies at Cz, in women compared to men. The effects of increased pyridine concentration on perception (larger in women) and CSERPs (similar across gender) imply that the two measures involve partially different neural processing. CSERP component identifiability is proposed here as a general means of assessing signal-to-noise ratio of the CSERPs. PMID:15337687

    Research has shown females' advantage in face memory, but few studies have used emotional faces as stimuli. In addition, it is unclear whether gender difference in memory for faces is mediated by individual factors especially associated with emotion. This study examined gender difference in recognition memory for neutral and emotional faces and whether arousal predisposition, emotion reappraisal, and emotion suppression can play a mediation role. Females (N=48) and males (N=45) viewed and memorised neutral, happy, and angry faces, and then took an immediate recognition test. The findings are: (1) Females outperformed males in recognition memory for happy faces, but not for neutral and negative faces. (2) Gender difference in recognition memory (including recollection and familiarity) was not mediated by arousal predisposition and emotion regulation. (3) Females had an own-sex bias in that they outperformed males with regard to recognition memory only for female faces, but not for male faces. The findings suggest that females' advantage is mediated by valence of face emotionality but not by arousal predisposition and emotion regulation, thus extending the literature by demonstrating the boundary condition for occurrence of females' advantage.

    Theory of Mind (ToM)--the ability to understand other's thoughts, intentions, and emotions--is important for navigating interpersonal relationships, avoiding conflict, and empathizing. Prior research has identified many factors that affect one's ToM ability, but little work has examined how different kinds of monetary incentives affect ToM ability. We ask: Does money affect ToM ability? If so, how does the effect depend on the structure of monetary incentives? How do the differences depend on gender? We hypothesize that money will affect ToM ability differently by gender: monetary rewards increase males' motivation to express ToM ability while simultaneously crowding out females' motivation. This prediction is confirmed in an experiment that varies the structure of monetary rewards for correct answers in the Reading the Mind in the Eyes Test (RMET). RMET scores decrease for females and increase for males with individual payments, and this effect is stronger with competitively-structured payments. RMET scores do not significantly change when monetary earnings go to a charity. Whether money improves or hinders ToM ability, and, hence, success in social interactions, thus depends on the interaction of gender and monetary incentive structure. PMID:26633171

This prediction is confirmed in an experiment that varies the structure of monetary rewards for correct answers in the Reading the Mind in the Eyes Test (RMET). RMET scores decrease for females and increase for males with individual payments, and this effect is stronger with competitively-structured payments. RMET scores do not significantly change when monetary earnings go to a charity. Whether money improves or hinders ToM ability, and, hence, success in social interactions, thus depends on the interaction of gender and monetary incentive structure. PMID:26633171

  13. Gender differences at birth and differences in fetal growth.

    The discrepancy between the number of boys and girls born has been interpreted as a natural selection response to differential survival prospects. There also exists a discrepancy in birth weight, length, head circumference at birth of boys and girls; on the other hand, placental weights were not so strongly biased by the sex of the fetus. Metabolic differences between the sexes are clearly recognized in adults. It is therefore argued that the anthropometric differences at birth, examples of which are presented in this paper, can only be achieved if the products of conception are also expressing a sexual bias in metabolism and physiology. It would then be this bias which would determine the efficiency of the implantation and growth processes and lead to rates of survival to birth. The speculation arising from this and the experimental manipulation of the sex ratio is that the physiological component most likely to be involved would be the lipid compartment with its strong sex difference.

    The cardiovascular responses of men and women to the stand test were compared by measuring respective values for heart rate, blood pressure, stroke volume, cardiac output, and total peripheral resistance during a 5-min supine and a 5-min standing test in ten subjects of each gender. It was found that, while the male and female subjects had similar heart rate values, all other responses exhibited greater changes in men than in women. While differences in the height of the subjects did not account for differences in cardiovascular responses, no mechanism responsible for these differences could be identified.

    While the relationship between psychopathic personality traits and substance use has received some attention (Hart & Hare, 1989; Smith & Newman, 1990), gender differences have not been thoroughly assessed. The current study examined whether gender modified the relationship between two criminally-relevant constructs, a) psychopathy and its factors and b) drug use. A sample of 318 participants with criminal histories and recent substance use was assessed for psychopathy using the Psychopathy Checklist: Screening Version and for illicit drug use using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders. As expected, the impulsive-antisocial traits (Factor 2) of psychopathy were positively related to a number of drug use characteristics (symptoms, age of drug initiation, extent of drug experimentation), whereas the interpersonal-affective traits (Factor 1) showed a negative relationship with drug abuse symptoms and a positive relationship with age of first use. In terms of gender differences, analyses revealed that women showed a stronger association between Factor 1 traits and later age of initiation compared to men, and that Factor 2, and antisocial facet in particular, were more strongly related to drug abuse in women than men. These findings suggest that psychopathic traits serve as both protective (Factor 1) and risk (Factor 2) correlates of illicit drug use, and in women, Factor 1 may be especially protective in terms of initiation. These conclusions add to the growing literature on potential routes to substance use and incarceration in women. PMID:26571339

    It is well established that many adolescents who smoke want to quit, but little is known about why adolescents want to quit and if reasons to quit differ across gender. The objective of this study was to determine if reasons to quit smoking differ in boys and girls. Data on the Adolescent Reasons for Quitting (ARFQ) scale were collected in mailed self-report questionnaires in 2010-2011 from 113 female and 83 male smokers aged 14-19 years participating in AdoQuest, a longitudinal cohort study of the natural course of the co-occurrence of health-compromising behaviors in children. Overall, the findings indicate that reasons to quit in boys and girls appear to be generally similar, although this finding may relate to a lack of gender-oriented items in the ARFQ scale. There is a need for continued research to develop and test reasons to quit scales for adolescents that include gender-oriented items. PMID:23863971

  18. Humor and gender roles: does age make a difference?

    PubMed

    Vitulli, William F

    2005-08-01

    Crawford's analysis in 2003 suggests that humor interacts with gender so that traditional social norms of femininity and masculinity may be reinforced or diinished. Yet age as a covariate was not considered. Assessment of the attitudes toward humor among 72 older women (M=72.0, SD=9.8, range=51-93 years) and 24 older men (M=69.8, SD=6.8, range=59-90 years) in 1996 by Vitulli and Parman suggest ratings on a Likert-type scale (anchored by 5: strongly agree and 1: strongly disagree) in which humor and gender interact. Moreover, a post hoc Scheffé test showed a significant sex effect on the female-oriented scale. Older women perceived humor as an important quality for women, whereas older men did not. Generational differences among studies on humor and sex underscore the need for contemporary research inclusive of age measures. PMID:16279321

    This secondary analysis from the National Adolescent Student Health Survey (NASHS) examined relationships between adolescents' personal and perceived peer attitudes toward condom use with gender and self-reported ethnic background. Descriptive results revealed general personal support and perceived peer support for condom use. Results from multivariate analysis of variance (MANOVAs) demonstrated significant interaction effects for the eighth grade sample [F = (4, 2383228) = 3530.01 p = .000], and the 10th grade sample [F = (4, 2636878) = 2594.41073, p = .000]. Contrasts revealed significant differences among all ethnic groups for both belief variables for the entire sample, eighth grade students, and 10th grade students. Though general support exists for condom use among U.S. eighth and 10th grade students, conviction varies among groups perhaps indicating a need for tailored messages about condom use, especially for Hispanic students. Implications for health education include the need for cultural-sensitive and gender-sensitive STD education. PMID:1619900

    Objective. We identified gender differences in psychiatric disorders among youths at probation intake. Methods. We measured disorders with the Voice Diagnostic Interview Schedule for Children among 991 randomly selected youths (200 girls) at probation intake in 8 Texas counties. Logistic regression analyses predicted diagnostic clusters by gender, adjusting for demographics and offense characteristics. Results. Demographic and offense characteristics explained small but interpretable and specific variance in diagnostic profile. Girls’ rates of anxiety and affective disorders were higher than boys’ (odds ratios = 0.59 and 0.32, respectively). Girls with violent offenses, compared with other groups, were 3 to 5 times as likely to report anxiety disorders. Conclusions. Among youths with conduct problems, girls demonstrated an elevated risk for co-occurring anxiety or affective disorder. PMID:15623873

    Objective Atherosclerosis is a complex process characterized by an increase in vascular wall thickness owing to the accumulation of cells and extracellular matrix between the endothelium and the smooth muscle cell wall. There is evidence that females are at lower risk of developing cardiovascular disease (CVD) as compared to males. This has led to an interest in examining the contribution of genetic background and sex hormones to the development of CVD. The objective of this review is to provide an overview of factors, including those related to gender, that influence CVD. Methods Evidence analysis from PubMed and individual searches concerning biochemical and endocrine influences and gender differences, which affect the origin and development of CVD. Results Although still controversial, evidence suggests that hormones including estradiol and androgens are responsible for subtle cardiovascular changes long before the development of overt atherosclerosis. Conclusion Exposure to sex hormones throughout an individual's lifespan modulates many endocrine factors involved in atherosclerosis. PMID:20460551

    Objective To examine gender differences in obtaining free alcohol, high-risk drinking, and consequences. Methods Web-based surveys were administered annually (2003–2005) to random samples of undergraduates (N=10,729). Results Gender, race, age under 21, sorority/fraternity membership, lower disposable income, and relationship status were significant predictors of obtaining free alcohol. Frequent obtainers had greater odds of heavy episodic drinking and consequences compared to infrequent obtainers. Females were less likely to report heavy episodic drinking; however, frequently obtaining females were more likely to report heavy episodic drinking. Conclusions Approximately 25% of undergraduates frequently obtained free alcohol. Females obtained more often, had higher odds of high-risk drinking, and experienced fewer consequences compared to males. PMID:22488395

    Prisons inmates have high rates of substance abuse and associated social and health problems, and a concomitant high need for drug treatment while incarcerated. Female inmates have an even greater treatment need, yet most inmates do not participate in treatment while incarcerated. Using data from a nationally representative sample of prison inmates, this article examines the impact of gender on prison treatment participation and gender differences in the factors associated with clinical treatment participation. Females were significantly more likely to participate in prison drug treatment than males, controlling for other factors. For both males and females, severity of drug problems predicted participation in treatment. For males but not females, race was associated with prison treatment participation, and among those with drug abuse or dependence, females with co-occurring mental health problems were more likely to participate in treatment. Implications for prison assessment and treatment policies, and future research, are discussed. PMID:21764764

  4. Describing Willow Flycatcher habitats: scale perspectives and gender differences

    1992-01-01

    We compared habitat characteristics of nest sites (female-selected sites) and song perch sites (male-selected sites) with those of sites unused by Willow Flycatchers (Empidonax traillii) at three different scales of vegetation measurement: (1) microplot (central willow [Salix spp.] bush and four adjacent bushes); (2) mesoplot (0.07 ha); and, (3) macroplot (flycatcher territory size). Willow Flycatchers exhibited vegetation preferences at all three scales. Nest sites were distinguished by high willow density and low variability in willow patch size and bush height. Song perch sites were characterized by large central shrubs, low central shrub vigor, and high variability in shrub size. Unused sites were characterized by greater distances between willows and willow patches, less willow coverage, and a smaller riparian zone width than either nest or song perch sites. At all scales, nest sites were situated farther from unused sites in multivariate habitat space than were song perch sites, suggesting (1) a correspondence among scales in their ability to describe Willow Flycatcher habitat, and (2) females are more discriminating in habitat selection than males. Microhabitat differences between male-selected (song perch) and female-selected (nest) sites were evident at the two smaller scales; at the finest scale, the segregation in habitat space between male-selected and female-selected sites was greater than that between male-selected and unused sites. Differences between song perch and nest sites were not apparent at the scale of flycatcher territory size, possibly due to inclusion of (1) both nest and song perch sites, (2) defended, but unused habitat, and/or (3) habitat outside of the territory, in larger scale analyses. The differences between nest and song perch sites at the finer scales reflect their different functions (e.g., nest concealment and microclimatic requirements vs. advertising and territorial defense, respectively), and suggest that the exclusive use of either nest or song perch sites in vegetation analyses can result in misleading, or at least incomplete, descriptions of a species' habitat. Habitat interpretations for Willow Flycatchers (and perhaps for many passerines) are a function of the gender-specific behavior of the birds observed and the scale of vegetation measurement.

    Gambling has typically been considered a predominately male activity. However, recent prevalence surveys have shown greater numbers of females are now gambling. Much of the gambling literature suggests online gamblers are more likely to be male, and that problem gamblers are more likely to be male. Males and females are also likely to be gambling for different reasons and have a preference for different gambling activities. Little is known about the pattern of play among female online gamblers. The aim of this survey was to develop a better profile of female online gamblers and to examine any gender differences between males and females in terms of how and why they gamble online, their frequency of online gambling, patterns of play, as well as attitudes to online gambling. The survey was posted on 32 international online gambling websites and was completed by 975 online gamblers (including 175 female online gamblers). Chi-square tests of association were conducted to examine the association between gender and a range of variables. The results showed that females had been gambling online for a shorter duration of time than males, had much shorter online gambling sessions, different motivations for gambling online (i.e., to practice for free, to spend less money and out of boredom), and experienced online gambling differently to males, with increased feelings of guilt and shame for gambling online. This suggests there is still a stigma around gambling particularly evident among females in this study. The findings indicate that clinicians and treatment providers need to be aware of these potential gender differences in online gambling to develop appropriately tailored interventions. PMID:23097131

    Published information concerning the influence of gender on mathematical ability tests has been controversial. The present study examines the performance of school-aged boys and girls from two age groups on several mathematical tasks and analyzes the predictive value of a verbal fluency test and a spatial test on those mathematical tasks. More specifically, our research attempts to answer the following two questions: (1) Are gender differences in mathematical test performance among children interrelated with age and (2) do verbal and spatial nonmathematical tests mediate gender effects on mathematical test performance? Two hundred and seventy-eight 7- to 10-year-old children and 248 13- to 16-year-olds were selected from schools in Colombia and Mexico (231 boys and 295 girls). The age effect was found to be significant for all measures, with scores improving with age. Results showed that boys and girls in both age groups scored similarly in most subtests, but that differences emerged in the performance of mental mathematical operations and in resolving arithmetical problems. In the latter - but not in mental math - older boys outperformed older girls, whereas no gender differences were observed in the younger groups. After controlling for age, it was found that the spatial test was, indeed, a significant mediator of gender effects, while the verbal task was not. PMID:18608220

    Data from 400 students in a tertiary mathematics course were analysed to explore gender differences on a number of variables associated with learning mathematics. It was concluded that while differences did occur on variables associated with confidence, self-concept, test anxiety and quantitative ability indicating a detrimental effect for women, compensating behaviour by women, including increased assignment work and tutorial attendance, resulted in comparable final course performance for women and men. These findings are discussed in light of participation rates of women in mathematics.

    Hemispatial neglect is a common and disabling consequence of stroke. Previous reports examining the relationship between gender and the incidence of unilateral spatial neglect (USN) have included either a large numbers of patients with few neglect tests or small numbers of patients with multiple tests. To determine if USN was more common and/or severe in men or women, we examined a large group of patients (312 right-handed) within 24 hours of acute right hemisphere ischemic stroke. Multiple spatial neglect tasks were used to increase the sensitivity of neglect detection. No differences based upon gender were observed for the prevalence, severity, or a combined task measure of USN. PMID:18406504

    HIV disclosure is a gateway to HIV prevention - particularly among couples living in regions severely affected by the HIV epidemic. This cross-sectional study utilizes data collected from 862 people living with HIV across three countries (Ethiopia, Mozambique, and Uganda) in 2011 to determine the role of partner disclosure on self-reported health perceptions and changes in sexual risk behavior. The study's secondary aims are to understand whether or not internalized stigma mediates this relationship and if there is a different pattern of results by gender. The multivariate analysis reveals that the three key HIV-related independent variables, belonging to a support group, doing volunteer work, and disclosing to one's spouse or partner, were significantly associated with lower levels of internalized stigma. Internalized stigma was associated with self-perceptions of poorer health for both women and men, with women reporting higher levels of internalized stigma than men. Disclosure to spouse was positively associated with perceptions of better health for women but not for men. For men, doing HIV-related volunteer work and disclosing their status to their spouse were positively associated with self-reported changes in sexual risk behavior, although stigma was not found to mediate this relationship. Findings from this study suggest that disclosure and stigma have gender-specific effects on individual well-being and changes in sexual risk behaviors. As such, programs must address gender inequity in disclosure patterns and stigma to enhance prevention efforts. PMID:24921155

    Gender differences exist in cardiovascular or metabolic disease risk, beyond the protective effect of estrogens, mostly burdening the postmenopausal female. We aimed to review herein sex differences in pro-inflammatory states, the independence of inflammation from insulin resistance, differences in high-density lipoprotein dysfunction, in gene-environment interactions, and in the influence of current and former smoking on cardiometabolic risk. Sex differences in absorption of long-chain fatty acids are highlighted. Differences exist in the first manifestation of cardiovascular disease, men being more likely to develop coronary heart disease as a first event, compared to women who have cerebrovascular disease or heart failure as a first event. Autoimmune activation resulting from pro-inflammatory states, a fundamental mechanism for numerous chronic diseases in people prone to metabolic syndrome, is much more common in women, and these constitute major determinants. Therapeutic approaches to aspects related to sex difference are briefly reviewed. PMID:26849352

    All over the world women are the predominant providers of informal care for family members with chronic medical conditions or disabilities, including the elderly and adults with mental illnesses. It has been suggested that there are several societal and cultural demands on women to adopt the role of a family-caregiver. Stress-coping theories propose that women are more likely to be exposed to caregiving stressors, and are likely to perceive, report and cope with these stressors differently from men. Many studies, which have examined gender differences among family-caregivers of people with mental illnesses, have concluded that women spend more time in providing care and carry out personal-care tasks more often than men. These studies have also found that women experience greater mental and physical strain, greater caregiver-burden, and higher levels of psychological distress while providing care. However, almost an equal number of studies have not found any differences between men and women on these aspects. This has led to the view that though there may be certain differences between male and female caregivers, most of these are small in magnitude and of doubtful clinical significance. Accordingly, caregiver-gender is thought to explain only a minor proportion of the variance in negative caregiving outcomes. A similar inconsistency characterizes the explanations provided for gender differences in caregiving such as role expectations, differences in stress, coping and social support, and response biases in reporting distress. Apart from the equivocal and inconsistent evidence, there are other problems in the literature on gender differences in caregiving. Most of the evidence has been derived from studies on caregivers of elderly people who either suffer from dementia or other physical conditions. Similar research on other mental illnesses such as schizophrenia or mood disorders is relatively scarce. With changing demographics and social norms men are increasingly assuming roles as caregivers. However, the experience of men while providing care has not been explored adequately. The impact of gender on caregiving outcomes may be mediated by several other variables including patient-related factors, socio-demographic variables, and effects of kinship status, culture and ethnicity, but these have seldom been considered in the research on gender differences. Finally, it is apparent that methodological variations in samples, designs and assessments between studies contribute a great deal to the observed gender differences. This review highlights all these issues and concludes that there is much need for further research in this area if the true nature of gender differences in family-caregiving of mental illnesses is to be discerned.

    Background RNA polymerase (pol) III transcribes a variety of untranslated RNAs responsible for regulating cellular growth and is deregulated in a variety of cancers. In this study, we examined gender differences in RNA pol III transcription in vitro and in vivo. Methods Expression levels of U6 snRNA, tMet, and known modulators of RNA pol III transcription were assayed in male and female derived adenocarcinoma (AC) lung cancer cell lines and male and female C57BL/6J mice using real time quantitative PCR. Methylation status of the U6 snRNA promoter was determined for lung and liver tissue isolated from male and female C57BL/6J mice by digesting genomic DNA with methylation sensitive restriction enzymes and digestion profiles were analyzed by qPCR using primers spanning the U6 promoter. Results Here, we demonstrate that RNA pol III transcription is differentially regulated by EGCG in male and female derived AC lung cancer cell lines. Basal RNA pol III transcript levels are significantly different in male and female derived AC lung cancer cell lines. These data prompted an investigation of gender specific differences in RNA pol III transcription in vivo in lung and liver tissue. Herein, we report that U6 snRNA RNA pol III transcription is significantly stimulated in the liver tissue of male C57BL/6J mice. Further, the increase in U6 transcription correlates with a significant inhibition in the expression of p53, a negative regulator of RNA pol III transcription, and demethylation of the U6 promoter in the liver tissue of male C57BL/6J mice. Conclusions To the best of our knowledge, this is the first study demonstrating gender specific differences in RNA pol III transcription both in vivo and in vitro and further highlights the need to include both male and female cell lines and animals in experimental design.

  18. Gender differences in the effect of unemployment on psychological distress.

    Ensminger, M E; Celentano, D D

    1990-01-01

    In this paper we examine whether unemployment has a differential impact on the expression of psychological distress among men and women. Based on the traditional centrality of the work role to men and the family role to women, we defined several key domains that might affect unemployed men and women differentially: family circumstances, concerns and worries about children and family; coping responses; social support and social integration; and the centrality of the work role. While the study population either were or hoped to be in the labor force and had dependent children, they varied in their marital status and whether they were the custodial parent. Using data collected in Baltimore from those who had been unemployed but had returned to work, those who had remained continuously unemployed for a year, and those who had been continuously employed, we compared the patterns of men's and women's reactions to unemployment. The important differences in psychological symptoms in this population were related to employment status, problems with parenting, financial difficulties, perceived lack of social support, hostility, and feelings about unemployment. By and large, the patterns of these relationships were similar for men and women. These findings suggest that when gender differences in psychological distress are found they may be due to differences in role configurations of men and women rather than intrinsic gender differences.

    Gender differences in the social anxiety spectrum and their correlation with other psychopathological features were analyzed in 520 students by using two questionnaires: the Social Anxiety Spectrum Self-Report (SHY-SR), which explores social anxiety spectrum, and the General Spectrum Measure (GSM), which explores panic-agoraphobia, mood, obsessive-compulsive, and eating-behavior features. Mean SHY-SR total score was significantly higher in women than in men, and gender differences were particularly pronounced for interpersonal sensitivity domain. Likewise, GSM scores were higher in women, except for the manic section. The SHY-SR domains correlated significantly with all GSM sections, except for the manic section. In conclusion, women reported more symptoms than men (who belonged to different psychopathologic dimensions) and displayed a profile of social anxiety spectrum that differs quantitatively but not qualitatively from the men's profile. The correlation between social anxiety spectrum and other psychopathological features mirrors previous findings concerning the high comorbidity of axis-I social anxiety disorder. PMID:11960083

    Empathy is a multidimensional construct and comprises the ability to perceive, understand and feel the emotional states of others. Gender differences have been reported for various aspects of emotional and cognitive behaviors including theory of mind. However, although empathy is not a single ability but a complex behavioral competency including different components, most studies relied on single aspects of empathy, such as perspective taking or emotion perception. To extend those findings we developed three paradigms to assess all three core components of empathy (emotion recognition, perspective taking and affective responsiveness) and clarify to which extent gender affects the neural correlates of empathic abilities. A functional MRI study was performed with 12 females (6 during their follicular phase, 6 during their luteal phase) and 12 males, measuring these tasks as well as self-report empathy questionnaires. Data analyses revealed no significant gender differences in behavioral performance, but females rated themselves as more empathic than males in the self-report questionnaires. Analyses of functional data revealed distinct neural networks in females and males, and females showed stronger neural activation across all three empathy tasks in emotion-related areas, including the amygdala. Exploratory analysis of possible hormonal effects indicated stronger amygdala activation in females during their follicular phase supporting previous data suggesting higher social sensitivity and thus facilitated socio-emotional behavior. Hence, our data support the assumption that females and males rely on divergent processing strategies when solving emotional tasks: while females seem to recruit more emotion and self-related regions, males activate more cortical, rather cognitive-related areas.

    Previous studies have consistently observed that women are more likely to perceive themselves as overweight compared to men. Similarly, women are more likely than men to report trying to lose weight. Less is known about the impact that self-perceived weight has on weight loss behaviors of adults and whether this association differs by gender. We conducted a cross-sectional analysis among an employee sample to determine the association of self-perceived weight on evidence-based weight loss behaviors across genders, accounting for body mass index (BMI) and demographic characteristics. Women were more likely than men to consider themselves to be overweight across each BMI category, and were more likely to report attempting to lose weight. However, perceiving oneself to be overweight was a strong correlate for weight loss attempts across both genders. The effect of targeting accuracy of self-perceived weight status in weight loss interventions deserves research attention. PMID:19188102

    We previously reported on the success of a psychological intervention implemented to reduce gender differences in achievement in an introductory college physics course. In this prior study, we found that the gender gap on exams and the FMCE among students who completed two 15-minute self-affirmation writing exercises was significantly reduced compared to the gender gap among students who completed neutral writing exercises. In a follow-up study we replicated the self-affirmation intervention in a later semester of the same course, with the same instructor. In this paper, we report the details and preliminary results of the replication study, where we find similar patterns along exams and course grades, but do not observe these patterns along the FMCE. We begin to investigate the critical features of replicating educational interventions, finding that replicating educational interventions is challenging, complex, and involves potentially subtle factors, some of which we explore and others that require further research.

  3. Gender differences in the diagnosis and treatment of HIV.

    Many cases of HIV infection in women in the United States are diagnosed very late in the course of their illness. HIV testing should be routinely recommended if a woman presents with certain gynecologic conditions or sexually transmitted diseases. Lack of awareness of HIV status leads to the majority of new sexually transmitted HIV infections. In the United States, most AIDS cases diagnosed among females in 2004 were attributable to high-risk heterosexual contact, disproportionately affecting black and Hispanic women. Depending on the racial/ethnic community being served, obstacles to access to care, including poverty, transportation issues, and cultural and language barriers, must be overcome. The full implications of gender differences in viral load and CD4 count in the treatment of women with HIV are not yet known. Clinical trial data on HIV therapies in women are limited, and most studies that have included women have not been powered to detect gender differences in virologic and immunologic success rates. Timing and choice of treatment are affected by the pharmacokinetics of antiretroviral drugs and the long-term complications of treatment, both of which may be different for men and women with HIV infection.

    Adolescents' gender-specific cannabis use rates and their correlates were examined. Data were obtained via a cross-sectional survey conducted in 2004 in British Columbia, Canada, funded by the Canadian Institutes of Health Research. School districts were invited to participate, and schools within consenting districts were recruited. In total, 8,225 students (50% male)from Grades 7 to 12 participated. About 73% were “White” and 47% had used cannabis in their lifetime. Cannabis users were grouped according to their frequency of use: “never users” “frequent users” or “heavy users” Male heavy cannabis users (14.3% of boys) were more likely to be in Grade 9 or higher; be Aboriginal; report poorer economic status; never feel like an outsider; frequently use alcohol and tobacco; and have lower satisfaction with family, friends, and school compared with boys that never used. Female heavy users (8.7% of girls) were more likely to be in a higher grade; report poorer economic status, mental health, and academic performance; frequently use alcohol and tobacco; and have lower satisfaction with their school compared with female never users. Three important gender differences in the multivariate analysis of the correlates of cannabis use were noted: school grade (for boys only), Aboriginal status (for boys only), and mental health (for girls only). Despite the limitations of relying on self-reports, a subset of youth appears to be at risk for excessive cannabis use that may impair life opportunities and health. The gender differences may be important in the design and implementation of prevention or treatment programs for adolescents. PMID:18696378

    A female advantage in school marks is a common finding in education research, and it extends to most course subjects (e.g., language, math, science), unlike what is found on achievement tests. However, questions remain concerning the quantification of these gender differences and the identification of relevant moderator variables. The present meta-analysis answered these questions by examining studies that included an evaluation of gender differences in teacher-assigned school marks in elementary, junior/middle, or high school or at the university level (both undergraduate and graduate). The final analysis was based on 502 effect sizes drawn from 369 samples. A multilevel approach to meta-analysis was used to handle the presence of nonindependent effect sizes in the overall sample. This method was complemented with an examination of results in separate subject matters with a mixed-effects meta-analytic model. A small but significant female advantage (mean d = 0.225, 95% CI [0.201, 0.249]) was demonstrated for the overall sample of effect sizes. Noteworthy findings were that the female advantage was largest for language courses (mean d = 0.374, 95% CI [0.316, 0.432]) and smallest for math courses (mean d = 0.069, 95% CI [0.014, 0.124]). Source of marks, nationality, racial composition of samples, and gender composition of samples were significant moderators of effect sizes. Finally, results showed that the magnitude of the female advantage was not affected by year of publication, thereby contradicting claims of a recent "boy crisis" in school achievement. The present meta-analysis demonstrated the presence of a stable female advantage in school marks while also identifying critical moderators. Implications for future educational and psychological research are discussed. PMID:24773502

    The ank (progressive ankylosis) mutant mouse, which has a nonsense mutation in exon 12 of the inorganic pyrophosphate regulator gene (ank), exhibits aberrant joint ankylosis similar to human ankylosing spondylitis (AS). We previously performed family-based association analyses of 124 Caucasian AS families and showed that novel genetic markers in the 5' flanking region of ANKH (the human homolog of the murine ank gene) are modestly associated with AS. The objective of the present study was to conduct a more extensive evaluation of ANKH variants that are significantly associated with AS and to determine whether the association is gender specific. We genotyped 201 multiplex AS families with nine ANKH intragenetic and two flanking microsatellite markers, and performed family-based association analyses. We showed that ANKH variants located in two different regions of the ANKH gene were associated with AS. Results of haplotype analyses indicated that, after Bonferroni correction, the haplotype combination of rs26307 [C] and rs27356 [C] is significantly associated with AS in men (recessive/dominant model; P = 0.004), and the haplotype combination of rs28006 [C] and rs25957 [C] is significantly associated with AS in women (recessive/dominant model; P = 0.004). A test of interaction identified rs26307 (i.e. the region that was associated in men with AS) as showing a difference in the strength of the association by gender. The region associated with AS in women only showed significance in the test of interaction among the subset of families with affected individuals of both genders. These findings support the concept that ANKH plays a role in genetic susceptibility to AS and reveals a gender–genotype specificity in this interaction. PMID:15899038

    In a manuscript entitled, “Bashful boys and coy girls: A review of gender differences in childhood shyness” Doey et al. (2013) suggest that shyness and its related constructs pose a greater developmental risk for boys compared to girls. They support this claim by citing empirical evidence suggesting that shy and anxiously withdrawn boys are responded to more negatively by important others (i.e., parents, peers, and teachers) and that the relationship between internalizing problems and anxious withdrawal is stronger for boys compared to girls. The principal aim of our commentary is to provide a critical examination of Doey et al.’s conclusions vis-à-vis gender differences in child and adolescent shyness. In this response, we begin by providing important theoretical background regarding shyness and its related constructs. Next, we critically examine the two main arguments the authors use in support of their conclusion through a review of existing empirical and theoretical work as well as the presentation of data from The Friendship Project. These data were analyzed with the specific purpose of providing an empirical test of the hypotheses implicit in Doey et al.’s primary arguments: 1) shy and anxiously withdrawn boys are responded to more negatively than girls and 2) the association between anxious withdrawal and internalizing problems is stronger for boys compared to girls. Our results indicate mixed support for these two claims. Finally, we conclude by suggesting new directions for future researchers interested in clarifying the relationship between gender and both the correlates and outcomes of childhood shyness.

    Two potential contributing factors to post-spaceflight orthostatic intolerance are decreases in baroreflex sensitivity (BRS) and sympathetic nervous system response. The purpose of this study was to examine the shape of the BRS curve and sympathetic response to a wide range of blood pressures (BP) before and during 6 head-down bed rest (BR). METHODS: Normal volunteers were tested one day before BR (20M, 1 0F) and near BR days 30 (20M, 10F), 60 (16M, 8F), and 90 (1 0M, 5F). BP was pharmacologically manipulated by 10-min infusions of phenylephrine (PE) and sodium nitroprusside (SNP) at 3 increasing concentrations with a 20-min rest between PE and SNP. Electrocardiogram and continuous finger blood pressure were recorded. A blood sample was drawn at the end of each infusion to measure plasma norepinephrine levels. The spontaneous baroreflex slope (SBS), a measure of BRS, was calculated as the slope of a sequence of 3 or more beats in which the systolic BP (SBP) and following R-R interval (RR) both increased or decreased. The data included saturated responses at the upper but not the lower end of the BP range. Mean response curves were constructed using second-order mixed model analysis. Results are based on term significance in the models. RESULTS RR: RR was lower during BR than pre BR (p<0.001). Pre BR males were modeled by a linear RR response to SBP (p=0.000) while females had a quadratic response which saturated at high SBP (p=0.019). By day 30, both genders were modeled by a linear response; compared to males, females had an attenuated (lower slope) RR response to changes in SBP (p=0.031). SBS: SBS vs SBP analysis showed a lower SBS during BR (p<0.001) when compared to pre BR. Females had a higher SBS than males pre BR (p=0.006). Females exhibited saturating SBS at higher SBP (p=0.016) on day 30, while males were modeled by a linear SBS response to SBP (p=0.035). NE: Females had different NE response to diastolic BP than males pre BR (p=0.035) and on day 30 (p=0.005). CONCLUSION: NE, RR and SBS responses to BP are affected by gender and BR. Not only do gender and BR baseline differences exist, but gender and BR also influence the slope and saturation of the BRS curves. Attenuated and saturating RR and SBS responses, as well as differences in baseline values, may contribute to the higher rates of orthostatic intolerance in women and after bed rest.

    Eleven male walleyes (Sander vitreus) and 10 female walleyes from the Saginaw Bay (Lake Huron) population were caught during the spawning run at Dow Dam (Midland, Michigan) in the Tittabawassee River during April 1996, and individual whole-fish polychlorinated biphenyl (PCB) determinations were made. Total PCB concentrations averaged 7.95 and 3.17??mg/kg for males and females, respectively. As part of the Natural Resource Damage Assessment remediation process, contaminated sediments from the Saginaw River, the main tributary to Saginaw Bay, were removed during 2000 and 2001. Total PCB concentrations of 10 male and 10 female walleyes caught at Dow Dam during April 2007 averaged 1.58 and 0.55??mg/kg, respectively. Thus, dredging of the Saginaw River appeared to be effective in reducing PCB concentrations of Saginaw Bay adult walleyes, as both males and females decreased in PCB concentration by more than 80% between 1996 and 2007. However, the ratio of male PCB concentration to female PCB concentration did not decline between 1996 and 2007. This persistent gender difference in PCB concentrations was apparently due to a gender difference in habitat utilization coupled with a persistent spatial gradient in prey fish PCB concentrations from the Saginaw River to Lake Huron.

    Women are more likely than men to forgo, delay, and ration medical care because of medical debt. Using 2003-04 Community Tracking Study Household Survey data, this study examined gender differences in five financial hardships associated with medical debt. Regression analyses accounting for predisposing, enabling, and need factors of health services use indicated women were less likely to report being contacted by a collection agency (b=-0.15, p<.05), using savings (b=-0.23, p<.005), or having any financial hardships associated with medical debt (b=-0.24, p<.05). There were no significant gender differences in putting off major purchases, borrowing money, and problems paying for necessities. Similarly, there were positive and negative relationships between medical debt financial hardships and income, insurance, and health status. Findings suggest that making health care affordable and equitable is critically important for both men and women. Research is needed to understand the differential impact of medical debt, especially among disadvantaged populations. PMID:21317529

    This descriptive study examined gender differences related to attitudes toward suicide among randomly selected urban residents. Data was collected using a standardized questionnaire through face-to-face interview. Our findings revealed that men hold more pro preventive attitudes to help persons with suicidal thoughts (80.3 %, p = 0.05) and agreed that suicidal attempts are impulsive (78.6 %, p = 0.01). However, they hold permissive attitude to help persons with incurable diseases and expressing death wishes to die (66 %, p = 0.05). A majority of men (78.6 %) than women agreed that "suicidal attempt is essentially a cry for help" (χ (2) = 11.798, p = 0.05). These gender differences need to be taken into consideration when developing appropriate programs to prevent suicide. Further, decriminalizing the law, high-quality research and raising awareness about suicide prevention among the general population is crucial in developing countries like India. PMID:26293749

    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.

    2014-01-01

    Due to the worldwide epidemic of obesity, nonalcoholic fatty liver disease (NAFLD) has become the most common cause of elevated liver enzymes. NAFLD represents a spectrum of liver injury ranging from simple steatosis to nonalcoholic steatohepatitis (NASH) which may progress to advanced fibrosis and cirrhosis. Individuals with NAFLD, especially those with metabolic syndrome, have higher overall mortality, cardiovascular mortality, and liver-related mortality compared with the general population. According to the population-based studies, NAFLD and NASH are more prevalent in males and in Hispanics. Both the gender and racial ethnic differences in NAFLD and NASH are likely attributed to interaction between environmental, behavioral, and genetic factors. Using genome-wide association studies, several genetic variants have been identified to be associated with NAFLD/NASH. However, these variants account for only a small amount of variation in hepatic steatosis among ethnic groups and may serve as modifiers of the natural history of NAFLD. Alternatively, these variants may not be the causative variants but simply markers representing a larger body of genetic variations. In this article, we provide a concise review of the gender and racial differences in the prevalence of NAFLD and NASH in adults. We also discuss the possible mechanisms for these disparities.

    Few investigations of sexual attitudes have restricted their focus to individuals' preferences for specific behaviors within a heterosexual relationship. None have examined gender differences in a broad and multidimensional array of such behavioral particulars. As part of an effort to develop a measure of preferred scripts in heterosexual couples, 258 men and women reported how much they agreed or disagreed with 74 statements of preference. A reduced and factor analyzed questionnaire included 38 items and was administered to a second sample (N = 228). Results offer qualified support that, compared to women, men are more erotophilic and show a stronger preference for incorporating erotic materials as well as drugs and alcohol into sexual relations with their partner. These results were more robust in the second sample, in which almost half of the subjects were tested in same-sex groups. Across both samples, women showed stronger preferences for activities reflecting romanticism. No gender differences were evident in sexual conventionality or in preference regarding the general use of contraceptives. However, results suggest that both sexes respond more favorably to a partner-focused or unspecified contraceptive method than to a self-focused method. PMID:7897676

    Purpose Gender differences in paediatric patients with inflammatory bowel disease (IBD) are frequently reported as a secondary outcome and the results are divergent. To assess gender differences by analysing data collected within the Swiss IBD cohort study database since 2008, related to children with IBD, using the Montreal classification for a systematic approach. Methods Data on gender, age, anthropometrics, disease location at diagnosis, disease behaviour, and therapy of 196 patients, 105 with Crohn's disease (CD) and 91 with ulcerative or indeterminate colitis (UC/IC) were retrieved and analysed. Results The crude gender ratio (male : female) of patients with CD diagnosed at <10 years of age was 2.57, the adjusted ratio was 2.42, and in patients with UC/IC it was 0.68 and 0.64 respectively. The non-adjusted gender ratio of patients diagnosed at ?10 years was 1.58 for CD and 0.88 for UC/IC. Boys with UC/IC diagnosed <10 years of age had a longer diagnostic delay, and in girls diagnosed with UC/IC >10 years a more important use of azathioprine was observed. No other gender difference was found after analysis of age, disease location and behaviour at diagnosis, duration of disease, familial occurrence of IBD, prevalence of extra-intestinal manifestations, complications, and requirement for surgery. Conclusion CD in children <10 years affects predominantly boys with a sex ratio of 2.57; the impact of sex-hormones on the development of CD in pre-pubertal male patients should be investigated.

    Decision often implies a utilitarian choice based on personal gain, even at the expense of damaging others. Despite the social implications of utilitarian behavior, its neurophysiological bases remain largely unknown. To assess how the human brain controls utilitarian behavior, we delivered transcranial direct current stimulation (tDCS) over the ventral prefrontal cortex (VPC) and over the occipital cortex (OC) in 78 healthy subjects. Utilitarian judgment was assessed with the moral judgment task before and after tDCS. At baseline, females provided fewer utilitarian answers than males for personal moral dilemmas (p = .007). In males, VPC-tDCS failed to induce changes and in both genders OC-tDCS left utilitarian judgments unchanged. In females, cathodal VPC-tDCS tended to decrease whereas anodal VPC-tDCS significantly increased utilitarian responses (p = .005). In males and females, reaction times for utilitarian responses significantly decreased after cathodal (p<.001) but not after anodal (p = .735) VPC-tDCS. We conclude that ventral prefrontal tDCS interferes with utilitarian decisions, influencing the evaluation of the advantages and disadvantages of each option in both sexes, but does so more strongly in females. Whereas cathodal tDCS alters the time for utilitarian reasoning in both sexes, anodal stimulation interferes more incisively in women, modifying utilitarian reasoning and the possible consequent actions. The gender-related tDCS-induced changes suggest that the VPC differentially controls utilitarian reasoning in females and in males. The gender-specific functional organization of the brain areas involved in utilitarian behavior could be a correlate of the moral and social behavioral differences between the two sexes.

    Previous research has demonstrated that women and men tend to have different types of mental and physical health problems. Using data from the US National Comorbidity Survey Replication (NCS-R) of 2001-2003, we consider whether the female excess in internalizing disorders contributes to the female excess in chronic debilitating conditions and whether the male excess in externalizing disorders contributes to the male excess in life threatening conditions. We find that women have significantly higher odds of meeting the DSM-IV criteria for one or more lifetime internalizing disorders and significantly lower odds of meeting the DSM-IV criteria for one or more lifetime externalizing disorders. We also find that women have higher odds of reporting four of the ten chronic debilitating conditions examined, including arthritis, frequent or severe headaches, seasonal allergies, and gallbladder removal, and lower odds of reporting three of the six life threatening conditions examined, including stroke, heart disease, and high blood pressure. We conclude that the female excess in internalizing disorders partially mediates, or explains, the female excess in arthritis, headaches, and gallbladder removal, while the male excess in externalizing disorders partially accounts for the male excess in heart disease and high blood pressure.

    Young, Deidra J.; Fraser, Barry J.

    The problem of the underrepresentation of girls in science in Australian schools is often attributed to their poor performance. Yet the role of both the home and the school in affecting female science achievement is rarely examined empirically. The comprehensiveness of the Second International Science Study database provided an excellent opportunity to investigate the presence of gender differences in science achievement. Although previous studies of gender differences in science achievement have relied on methodology that has not adequately accounted for the school effects, this study used the design effect and hierarchical linear modeling (multilevel analysis) to explore whether there were significant gender differences. The relative contribution of schools to student achievement was examined, and school-level differences were found to contribute significantly toward explaining variations in student performance. Although statistically significant sex differences were found in physics achievement for 10-year-old, 14-year-old, and year-12 students, school effects were much more powerful in explaining student differences (9-19%) when compared with gender (3%).

    This study analyzed cross-sectional data to examine gender differences in the association of sleep quality and daytime sleepiness with mood and functional outcomes in adults with type 2 diabetes (T2DM). Measures included demographic and clinical data as well as scales that measured subjective daytime sleepiness, sleep quality, mood disturbances, and functional outcomes. The majority of the sample (N = 116) had poor sleep quality and was subjectively sleepy. We observed in males and females significantly different associative patterns between the predictor variables of daytime sleepiness and sleep quality and the outcome variables of mood and functional outcome. There was no significant difference in daytime sleepiness or impaired sleep quality between men and women with T2DM; however, there was a difference in the expression of impaired sleep on mood and functional outcomes between genders.

    Conclusions regarding HIV stigma in rural areas are hampered by lack of agreement about rural classification. This investigation examined perceptions of HIV stigma among males and females with HIV/AIDS in metropolitan, micropolitan, and rural areas. Two-hundred people with HIV/AIDS completed a measure of perceived HIV stigma. Their county or town of residence was used to classify community size. Results indicated that community size was related to one aspect of perceived stigma, disclosure concerns, differently for men and women. Rural women reported more disclosure concerns than did metropolitan and micropolitan women. They also reported more disclosure concerns than rural men. Men in micropolitan communities reported more disclosure concerns than men in rural areas and tended to report more disclosure concerns than men in metropolitan areas. Understanding the relationship of community size to HIV stigmatization requires acknowledging that many communities are neither urban nor rural, and it requires considering gender differences.

    This paper examines gender differences in risk aversion among Chinese university students. Chinese females are proposed to be more risk averse and require a higher risk premium when faced with a gamble option in the gain-domain frame as compared to Chinese males. Two groups of 100 participants each (male = 100 and female = 100 in total) were recruited to fill up questionnaires that included items relating to objective probability lotteries. Within each group, it was found that Chinese males and females did not differ in their risk aversion. However, results show that Chinese males tend to react more readily to rising risk premium by taking up options with higher expected values when compared to Chinese females. Current findings will have useful implications to marketers (particularly, promoters of gambling products) and problem gambling counselors. PMID:25112219

    This study examines the gender differences in the enjoyment of recreational sports participation among Taiwanese adults. Data were obtained using the 2007 Taiwan Social Change Survey. The questionnaire included a topical module of the International Social Survey Program regarding leisure time and sports. Results showed that male subjects were more likely to participate in recreational sports to improve their appearance and on account of their personal interest. In addition to these factors, female subjects also experienced greater motivation to participate when Taiwanese athletes performed well in international sporting competitions. This study confirmed that the factors influencing enjoyment of recreational sports participation differ among men and women. These results can be used to better inform public health professionals and other regulatory organizations formulating physical activity intervention strategies. PMID:25599374

    During sepsis, a complex network of cytokine, immune, and endothelial cell interactions occur and disturbances in the microcirculation cause organ dysfunction or even failure leading to high mortality in those patients. In this respect, numerous experimental and clinical studies indicate sex-specific differences in infectious diseases and sepsis. Female gender has been demonstrated to be protective under such conditions, whereas male gender may be deleterious due to a diminished cell-mediated immune response and cardiovascular functions. Male sex hormones, i.e., androgens, have been shown to be suppressive on cell-mediated immune responses. In contrast, female sex hormones exhibit protective effects which may contribute to the natural advantages of females under septic conditions. Thus, the hormonal status has to be considered when treating septic patients. Therefore, potential therapies could be derived from this knowledge. In this respect, administration of female sex hormones (estrogens and their precursors) may exert beneficial effects. Alternatively, blockade of male sex hormone receptors could result in maintained immune responses under adverse circulatory conditions. Finally, administration of agents that influence enzymes synthesizing female sex hormones which attenuate the levels of pro-inflammatory agents might exert salutary effects in septic patients. Prospective patient studies are required for transferring those important experimental findings into the clinical arena. PMID:24193307

    Stigma associated with HIV/AIDS directly and indirectly drives HIV transmission. We examined how factors associated with HIV-related stigma differed by gender, using data from the 2008-2009 Kenya Demographic and Health Survey (KDHS). Descriptive, bivariate and multinomial logistic regression analyses were conducted on selected HIV-related stigma indicators for men and women. Bivariate analyses showed significant gender differences in the overall HIV Stigma index with a higher proportion of women than men presented at the highest stigma level (4.9% vs 2.7%, p < 0.01). Women were more likely to express higher stigmatic attitudes for all components of stigma measured than men. Multivariate analyses showed that HIV-related knowledge had significant inverse dose-response for both men and women. For instance, compared to women in the first HIV-related knowledge quartile, a 1 unit increase in HIV-related knowledge among women at the third HIV-related knowledge quartile was expected to lead to a 63.8% decrease in HIV-related stigma (95% CI [0.21, 0.63]) for women with high stigma, 57.8% decrease for similar women with medium stigma (95% CI [0.33, 0.55]) and 28.4% decrease for those with low stigma (95% CI [0.57, 0.90]). Acceptance with the statement "a husband is justified to hit or beat his wife if she refuses to have sex with him" was a significant risk factor for expression of stigmatising attitudes at all levels for women (High: OR = 1.49, 95% CI [1.02, 2.17]), Medium: OR = 1.47, 95% CI [1.18, 1.82], Low: OR = 1.38, 95% CI [1.10, 1.73]) and men at medium stigma (OR = 2.02, 95% CI [1.38, 2.95]). Other notable gender differences were found in employment, marital status, ethnicity, region of residence, wealth and media exposure. Our results showed that women in the general Kenyan population had higher stigmatic attitudes than men. This was associated with differences in risk factor profile and confirmed previous literature on complexity of social-cultural factors associated with HIV-related stigma. PMID:23795954

    Susceptibility to environmental stressors has been described for fetal and early childhood development. However, the possible susceptibility of the prepubertal period, characterized by the orchestration of the organism towards sexual maturation and adulthood has been poorly investigated and exposure data are scarce. In the current study levels of cadmium (Cd), cotinine and creatinine in urine were analyzed in a subsample 216 children from 12 European countries within the DEMOCOPHES project. The children were divided into six age–sex groups: boys (6–8 years, 9–10 years and 11 years old), and girls (6–7 years, 8–9 years, 10–11 years). The number of subjects per group was between 23 and 53. The cut off values were set at 0.1 µg/L for Cd, and 0.8 µg/L for cotinine defined according to the highest limit of quantification. The levels of Cd and cotinine were adjusted for creatinine level. In the total subsample group, the median level of Cd was 0.180 µg/L (range 0.10–0.69 µg/L), and for cotinine the median wet weight value was 1.50 µg/L (range 0.80–39.91 µg/L). There was no significant difference in creatinine and cotinine levels between genders and age groups. There was a significant correlation between levels of cadmium and creatinine in all children of both genders. This shows that even at such low levels the possible effect of cadmium on kidney function was present and measurable. An increase in Cd levels was evident with age. Cadmium levels were significantly different between 6–7 year old girls, 11 year old boys and 10–11 year old girls. As there was a balanced distribution in the number of subjects from countries included in the study, bias due to data clustering was not probable. The impact of low Cd levels on kidney function and gender differences in Cd levels needs further investigation. - Highlights: • In 216 children from 6 to 11 years old the median level of Cd was 0.18 µg/L. • The median level of cotinine was 1.50 µg/L. • Correlation between levels of Cd and creatinine in all children was detected. • Cd levels were different between 6–7 year old, 10–11 year old girls vs. 11 year old boys.

    The present study was designed to determine whether there are gender differences in hormonal response patterns to HPA axis activation. To this end, two methods of activating the HPA axis were employed: a standardized psychological stress test and a pharmacological challenge. Healthy subjects (mean age 23.4 years, SD 7.0 years) completed a naloxone challenge and/or the modified Trier Social Stress Test (TSST). For the naloxone challenge, two baseline blood samples were obtained. Placebo was then administered (0 min), followed by increasing doses of intravenous naloxone (50, 100, 200 and 400 microg/kg) at 30-min intervals. Post-placebo blood samples were collected at 15-min intervals for 180 min. The TSST consisted of 5 min of public speaking followed by 5 min of mental arithmetic exercises. Three baseline and five post-TSST blood samples were drawn. Eighty subjects (53 male, 27 female) underwent the TSST. Following the psychological stressor, adrenocorticotropin (ACTH) and cortisol responses were significantly greater in male subjects compared to female subjects (z=-2.34, p=0.019 and z=-2.12, p=0.034, respectively). Seventy-two subjects (52 male, 20 female) underwent HPA axis activation induced by naloxone. In contrast to the TSST, cortisol responses to the naloxone challenge were significantly greater in female subjects compared to male subjects (z=4.11, p<0.001). Forty-one subjects (25 male, 16 female) completed both the TSST and naloxone challenge. In this subset, ACTH and cortisol responses to the TSST did not differ significantly by gender, although the effect size was moderate to large. Adrenocorticotropin and cortisol responses to the naloxone challenge were significantly greater in female subjects compared to male subjects (z=2.29, p=0.022 and z=4.34, p<0.001, respectively). In summary, male subjects had greater HPA axis responses to a psychological stressor than female subjects, and females had greater hormonal reactivity than males to pharmacological stimulation with naloxone. Such differences are of interest as potential contributors to gender differences in health risks. PMID:16616815

  3. Neural Correlates of Sex/Gender Differences in Humor Processing for Different Joke Types

    Humor operates through a variety of techniques, which first generate surprise and then amusement and laughter once the unexpected incongruity is resolved. As different types of jokes use different techniques, the corresponding humor processes also differ. The present study builds on the framework of the ‘tri-component theory of humor,’ which details the mechanisms involved in cognition (comprehension), affect (appreciation), and laughter (expression). This study seeks to identify differences among joke types and between sexes/genders in the neural mechanisms underlying humor processing. Three types of verbal jokes, bridging-inference jokes (BJs), exaggeration jokes (EJs), and ambiguity jokes (AJs), were used as stimuli. The findings revealed differences in brain activity for an interaction between sex/gender and joke type. For BJs, women displayed greater activation in the temporoparietal–mesocortical-motor network than men, demonstrating the importance of the temporoparietal junction (TPJ) presumably for ‘theory of mind’ processing, the orbitofrontal cortex for motivational functions and reward coding, and the supplementary motor area for laughter. Women also showed greater activation than men in the frontal-mesolimbic network associated with EJs, including the anterior (frontopolar) prefrontal cortex (aPFC, BA 10) for executive control processes, and the amygdala and midbrain for reward anticipation and salience processes. Conversely, AJs elicited greater activation in men than women in the frontal-paralimbic network, including the dorsal prefrontal cortex (dPFC) and parahippocampal gyrus. All joke types elicited greater activation in the aPFC of women than of men, whereas men showed greater activation than women in the dPFC. To confirm the findings related to sex/gender differences, random group analysis and within group variance analysis were also performed. These findings help further establish the mechanisms underlying the processing of different joke types for the sexes/genders and provide a neural foundation for a theory of sex/gender differences in humor.

    Orthostatic intolerance is a recognized consequence of spaceflight. Numerous studies have shown that women are more susceptible to orthostatic intolerance following spaceflight as well as bed rest, the most commonly used ground-based analog for spaceflight. One of the possible mechanisms proposed to account for this is a difference in vascular responsiveness between genders. We hypothesized that women and men would have differing vascular responses to 90 days of 6-degree head down tilt bed rest. Additionally, we hypothesized that vessels in the upper and lower body would respond differently, as has been shown in the animal literature. Thirteen subjects were placed in bedrest for 90 days (8 men, 5 women) at the Flight Analogs Unit, UTMB. Direct arterial and venous measurements were made with ultrasound to evaluate changes in vascular structure and function. Arterial function was assessed, in the arm and leg, during a reactive hyperemia protocol and during sublingual nitroglycerin administration to gauge the contributions of endothelial dependent and independent dilator function respectively. Venous function was assessed in dorsal hand and foot veins during the administration of pharmaceuticals to assess constrictor and dilator function. Both gender and day effects are seen in arterial dilator function to reactive hyperemia, but none are seen with nitroglycerin. There are also differences in the wall thickness in the arm vs the leg during bed rest, which return toward pre-bed rest levels by day 90. More subjects are required, especially females as there is not sufficient power to properly analyze venous function. Day 90 data are most underpowered.

  5. Alcohol-induced blackout. Phenomenology, biological basis, and gender differences.

    2010-06-01

    Blackouts from acute alcohol ingestion are defined as the inability to recall events that occurred during a drinking episode and are highly prevalent in both alcoholic and nonalcoholic populations. This article reviews the clinical manifestations, epidemiology, risk factors, cognitive impairment, and neurobiology associated with alcohol-induced blackout, with special emphasis on the neurochemical and neurophysiological basis, and gender differences. Two types of blackout have been identified: en bloc, or complete inability to recall events during a time period, and fragmentary, where memory loss is incomplete. The rapidity of rise in blood alcohol concentration is the most robust predictor of blackout. Alcohol impairs different brain functions at different rates, and cognitive and memory performance are differentially impaired by ascending versus descending blood alcohol concentration. Cognitive and memory impairment occurs before motor impairment, possibly explaining how a drinker appearing fully functional can have little subsequent memory. Blackouts are caused by breakdown in the transfer of short-term memory into long-term storage and subsequent retrieval primarily through dose-dependent disruption of hippocampal CA1 pyramidal cell activity. The exact mechanism is believed to involve potentiation of gamma-aminobutyric acid-alpha-mediated inhibition and interference with excitatory hippocampal N-methyl-d-aspartate receptor activation, resulting in decreased long-term potentiation. Another possible mechanism involves disrupted septohippocampal theta rhythm activity because of enhanced medial septal area gamma-aminobutyric acid-ergic neurotransmission. Women are more susceptible to blackouts and undergo a slower recovery from cognitive impairment than men, due in part to the effect of gender differences in pharmacokinetics and body composition on alcohol bioavailability.

    Background: 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. Aims: To evaluate and compare gender differences in the prevalence of depression and anxiety in AD. Materials and Methods: 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. Results: 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). Conclusions: There is a female preponderance of depression and anxiety disorder in AD patients. PMID:25814727

    Macroprolactinomas are the most common functional pituitary tumours. Hypotheses proposed to explain predominance of large tumours in males are: i) diagnostic delay, as hyperprolactinaemia remains under recognised in males and ii) gender-specific difference in tumour proliferation indices. Our study objectives are to compare gender differences in clinical, biochemical, radiological features, management outcomes and cabergoline responsiveness in macroprolactinomas. Drug resistance was defined as failure to achieve prolactin normalisation and >50% reduction in tumour volume with cabergoline (3.5 mg/week dose for minimum 6 months duration). The baseline characteristics of 100 patients (56 females and 44 males) with macroprolactinoma were analysed. Drug responsiveness was analysed in 88 treatment naive patients, excluding 12 post-primary trans-sphenoidal surgery cases. We found that females (30.29±10.39 years) presented at younger mean age than males (35.23±9.91 years) (P<0.01). The most common presenting symptom was hypogonadism (oligo-amenorrhoea/infertility) in females (96.15%) and symptoms of mass effect (headache and visual field defects) in males (93.18%). Baseline mean prolactin levels were significantly lower in females (3094.36±6863.01 ng/ml) than males (7927.07±16 748.1 ng/ml) (P<0.001). Maximal tumour dimension in females (2.49±1.48 cm) was smaller than males (3.93±1.53 cm) (P<0.001). In 88 treatment naïve patients, 27.77% females and 35.29% males had resistant tumours (P=0.48). On subgrouping as per maximum tumour dimension (1.1-2 cm, 2.1-4 cm and >4 cm), gender difference in response rate was insignificant. In conclusion, macroprolactinomas are equally prevalent in both sexes. Macroprolactinomas in males predominantly present with symptoms of mass effects, as against females who present with symptoms of hypogonadism. Males harbor larger tumours but are equally cabergoline responsive as those in females. PMID:26682970

    Macroprolactinomas are the most common functional pituitary tumours. Hypotheses proposed to explain predominance of large tumours in males are: i) diagnostic delay, as hyperprolactinaemia remains under recognised in males and ii) gender-specific difference in tumour proliferation indices. Our study objectives are to compare gender differences in clinical, biochemical, radiological features, management outcomes and cabergoline responsiveness in macroprolactinomas. Drug resistance was defined as failure to achieve prolactin normalisation and >50% reduction in tumour volume with cabergoline (3.5 mg/week dose for minimum 6 months duration). The baseline characteristics of 100 patients (56 females and 44 males) with macroprolactinoma were analysed. Drug responsiveness was analysed in 88 treatment naive patients, excluding 12 post-primary trans-sphenoidal surgery cases. We found that females (30.29±10.39 years) presented at younger mean age than males (35.23±9.91 years) (P<0.01).

    Objective Gender differences are a well-known clinical characteristic of Parkinson’s disease (PD). In-vivo imaging studies demonstrated that women have greater striatal dopamine transporter (DAT) activity than do men, both in the normal population and in PD patients. We hypothesize that women exhibit more rapid aging-related striatal DAT reduction than do men, as the potential neuroprotective effect of estrogen wanes with age. Methods This study included 307 de novo PD patients (152 men and 155 women) who underwent DAT scans for an initial diagnostic work-up. Gender differences in age-related DAT decline were assessed in striatal sub-regions using linear regression analysis. Results Female patients exhibited greater DAT activity compared with male patients in all striatal sub-regions. The linear regression analysis revealed that age-related DAT decline was greater in the anterior and posterior caudate, and the anterior putamen in women compared with men; we did not observe this difference in other sub-regions. Conclusions This study demonstrated the presence of gender differences in age-related DAT decline in striatal sub-regions, particularly in the antero-dorsal striatum, in patients with PD, presumably due to aging-related decrease in estrogen. Because this difference was not observed in the sensorimotor striatum, this finding also suggests that women may not have a greater capacity to tolerate PD pathogenesis than do men. PMID:26413240

    Our objective was to study gender differences in delusional disorder (DD), by comparing potential risk factors, clinical correlates, illness course characteristics, and functionality. The sample was composed of 86 outpatients with DD (according to the SCID-I for DSM-IV criteria). The following assessment instruments were used service use and demographic questionnaires, Standardized Assessment of Personality (SAP), the Positive and Negative Symptom Scale (PANSS), Montgomery-Asberg Depression Rating Scale (MADRS), Mini-Mental State Examination (MMSE), Mini International Neuropsychiatry Interview (MINI), Sheehan Disability Inventory (SDI), and the Global Assessment of Functioning (GAF) scale. The female-to-male ratio was 1.6:1. Men were more likely to be single, while women were more likely to be widows. Men had a greater frequency of schizoid and schizotypal premorbid personality disorders and of premorbid substance abuse. There were no differences for other risk factors (immigration, deafness, late onset, other personality disorders, and family history). Men were younger at onset and more frequently had acute onset of the disorder. Men had more severe symptoms (higher score on the global or separate PANSS scales). There were no gender differences for the remaining symptomatological variables (types of DD, presence and severity of depression, presence of hallucinations, severity of global cognitive functioning and presence of axis I comorbidity). Global and partial (work, family, and social) functioning was significantly poorer among men. Course type and consumption of resources appeared to be similar. We conclude that men with DD had significantly more severe symptoms and worse functionality. They also had a higher frequency of schizoid and schizotypal premorbid personality disorders and premorbid substance abuse. PMID:20334930

    2011-10-01

    Gender differences are frequently observed in autobiographical memory (AM). However, few studies have investigated the neural basis of potential gender differences in AM. In the present functional MRI (fMRI) study we investigated gender differences in AMs elicited using dynamic visual images vs verbal cues. We used a novel technology called a SenseCam, a wearable device that automatically takes thousands of photographs. SenseCam differs considerably from other prospective methods of generating retrieval cues because it does not disrupt the ongoing experience. This allowed us to control for potential gender differences in emotional processing and elaborative rehearsal, while manipulating how the AMs were elicited. We predicted that males would retrieve more richly experienced AMs elicited by the SenseCam images vs the verbal cues, whereas females would show equal sensitivity to both cues. The behavioural results indicated that there were no gender differences in subjective ratings of reliving, importance, vividness, emotion, and uniqueness, suggesting that gender differences in brain activity were not due to differences in these measures of phenomenological experience. Consistent with our predictions, the fMRI results revealed that males showed a greater difference in functional activity associated with the rich experience of SenseCam vs verbal cues, than did females.

    With the aging of the population, the burden of Alzheimer’s disease (AD) is rapidly expanding. More than 5 million people in the US alone are affected with AD and this number is expected to triple by 2050. While men may have a higher risk of mild cognitive impairment (MCI), an intermediate stage between normal aging and dementia, women are disproportionally affected with AD. One explanation is that men may die of competing causes of death earlier in life, so that only the most resilient men may survive to older ages. However, many other factors should also be considered to explain the sex differences. In this review, we discuss the differences observed in men versus women in the incidence and prevalence of MCI and AD, in the structure and function of the brain, and in the sex-specific and gender-specific risk and protective factors for AD. In medical research, sex refers to biological differences such as chromosomal differences (eg, XX versus XY chromosomes), gonadal differences, or hormonal differences. In contrast, gender refers to psychosocial and cultural differences between men and women (eg, access to education and occupation). Both factors play an important role in the development and progression of diseases, including AD. Understanding both sex- and gender-specific risk and protective factors for AD is critical for developing individualized interventions for the prevention and treatment of AD. PMID:24470773

    2008-01-01

    Irritable bowel syndrome (IBS) is a chronic functional GI disorder characterized by abdominal pain associated with alterations in defecation or stool frequency and consistency. In Western industrialized countries, women seek health care services for their symptoms more frequently than men. The cause of IBS is likely multifactorial involving altered motility, visceral hypersensitivity, and dysregulation of the autonomic nervous system. Many patients note that their symptoms are exacerbated by diet and stress, and women frequently report menstrual cycle fluctuations in symptoms. Current approaches to IBS management include behavioral management therapies such as dietary intake changes and stress reduction cognitive restructuring. Drug therapies are targeted at altering pain sensitivity, motility, and secretion. This review provides an overview of the pathogenesis of IBS, factors that contribute to gender differences, and current therapeutic approaches for symptom management. PMID:18595860

    In the USA, women have consistently been proportionally underrepresented in science and technology (S&T). In these disciplines, as students move from high schools to colleges to graduate programs, qualified women drop out at higher rates than do men, resulting in a striking loss of talented students. Attitude toward a discipline is one of the major factors in students' choice of majors. As a result, attitudes toward S&T are issues with longstanding attention and interest in education research. Retention of female students in S&T majors remains a major concern. The purpose of the study was to investigate attitudes toward S&T including attitudes toward female participation in S&T, among S&T majors, and examine differences by gender and class standing. Such an investigation would provide deeper insights to help devise strategies to retain women in S&T majors.

    This study examined gender differences in 79 high-school students’ attitudes towards their science classes, their perceptions of science and scientists, and their views about majoring in science. The study identified some of the subtleties underlying females’ low participation in, and interest in, science documented in previous research. Four themes emerged from responses on the rating scales and questionnaire. First, even when females planned to major in science, they were more interested than males in the people-oriented aspects of their planned majors. Second, biology was the one exception to females’ low interest in science. Third, females often planned a science major mainly because they needed a science background in order to enter a health profession such as medicine or physical therapy. Fourth, females generally found science uninteresting and the scientific lifestyle (as perceived by them) unattractive. Implications for teaching science were discussed.

    Infant cries are a critical survival mechanism that draw the attention of adult caregivers, who can then satisfy the basic needs of otherwise helpless infants. Here, we used functional neuroimaging to investigate the effects of infant hunger cries on brain activity of adults who were in a cognitively non-demanding mental state of awake rest. We found that the brains of males and females, independent of parental status (parent or non parent), reacted differently to infant cries. Specifically, dorsal medial prefrontal and posterior cingulate areas, known to be involved in mind-wandering (the stream of thought typical of awake rest), remained active in men during exposure to infant cries, whereas in women activity in these regions decreased. These results reveal gender-dependent modulation of brain responses to infant requests to be fed, and specifically they indicate that women interrupt mind-wandering when exposed to the sounds of infant hunger cries, whereas men carry on without interruption.

It was shown that all the indices mentioned demonstrated highly significant gender differences if calculation of each of them was based, not on the body mass, but on a conventional body volume obtained by division of the factual body mass by the average statistical body density corresponding to 1.064 kg/dm3 in men and 1.034 kg/dm3 in women.

    Gender differences in cooperative choices and their neural correlates were investigated in a situation where reputation represented a crucial issue. Males and females were involved in an economic exchange (trust game) where economic and reputational payoffs had to be balanced in order to increase personal welfare. At the behavioral level, females showed a stronger reaction to negative reputation judgments that led to higher cooperation than males, measured by back transfers in the game. The neuroanatomical counterpart of this gender difference was found within the reward network (engaged in producing expectations of positive results) and reputation-related brain networks, such as the self-control network (engaged in strategically resisting the temptation to defect) and the mentalizing network (engaged in thinking about how one is viewed by others), in which the dorsolateral prefrontal cortex (DLPFC) and the medial (M)PFC respectively play a crucial role. Furthermore, both DLPFC and MPFC activity correlated with the amount of back transfer, as well as with the personality dimensions assessed with the Big-Five Questionnaire (BFQ-2). Males, according to their greater DLPFC recruitment and their higher level of the BFQ-2 subscale of Dominance, were more focused on implementing a profit-maximizing strategy, pursuing this target irrespectively of others' judgments. On the contrary, females, according to their greater MPFC activity and their lower level of Dominance, were more focused on the reputation per se and not on the strategic component of reputation building. These findings shed light on the sexual dimorphism related to cooperative behavior and its neural correlates. PMID:25180581

    This study investigated the possibility of gender differences in outcomes throughout the peer review process of American Fisheries Society (AFS) journals. For each manuscript submitted to four AFS journals between January 2003 and December 2010, we collated information regarding the gender and nationality of authors, gender of associate editor, gender of reviewers, reviewer recommendations, associate editor's decision, and publication status of the manuscript. We used hierarchical linear modeling to test for differences in manuscript decision outcomes associated with author, reviewer, and associate editor gender. Gender differences were present at some but not every stage of the review process and were not equal among the four journals. Although there was a small gender difference in decision outcomes, we found no evidence of bias in editors’ and reviewers’ recommendations. Our results support the conclusion that the current single-blind review system does not result in bias against female authors within AFS journals.

    Objectives To analyze the gender difference in life expectancy in Chinese urban people and explore the age-specific and cause-specific contributions to the changing gender differences in life expectancy. Methods Data of life expectancy and mortality were obtained from “Annual statistics of public health in China.” The gender difference was analyzed by decomposition method, including age-specific decomposition and cause-specific decomposition. Results Women lived much longer than men in Chinese urban areas, with remarkable gains in life expectancy since 2005, respectively. The gender difference reached a peak in 2007. Mortality difference between men and women in the 60–79 age group made the largest contributions to the gender gap in life expectancy in all 6 years. Among causes of death, cancers, circulatory diseases and respiratory diseases made the largest contributions to the gender gap. 33–38% of the gender gap were caused by cancers, among which lung cancer contributed 0.6 years of the overall gap. The contribution of cancers to the gender gap reduced over time, mostly influenced by the narrowing effect of liver cancer on gender gap. Traffic accidents and suicide were the external causes influencing the gender gap, contributing 10–16% of the overall difference. Conclusion Public health efforts to reduce excess mortalities for cancers, circulatory disease, respiratory diseases, and suicide among men in particular might further narrow the gender gap in life expectancy in Chinese cities.

    To investigate differences in learning gains by gender, we collected data in large introductory astronomy and biology courses. Male astronomy students had significantly higher pre- and post-test scores than female students on the astronomy diagnostic test. Male students also had significantly higher pretest and somewhat higher post-test scores than female students on a survey instrument designed for an introductory biology course. For both courses, males had higher learning gains than female students only when the normalized gain measure was utilized. No differences were found with any other measures, including other gain calculations, overall course grades, or individual exams. Implications for using different learning gain measures in science classrooms, as well as for research on learning differences by gender are discussed.

    This study examined media use and psychological adjustment (as indicated by depression and anxiety symptomatology) in a sample of 328 14- to 16-year-old adolescents. Primary goals of the study were to explore whether media use differs by gender, whether media use is related to adolescent psychological problems, and whether media use moderates the relationship between parental alcoholism and adolescent psychological adjustment. Adolescents were surveyed in the spring of 2006, and again one year later. Gender differences in media use were observed with boys spending more time playing video games than girls and girls spending more time talking on the phone than boys. Strikingly, none of the types of media examined was associated with depression or anxiety. Moreover, media use acted as a protective factor for boys. Boys who spent relatively more time playing video games and watching television had the lowest levels of anxiety, especially those from alcoholic homes. The opposite pattern emerged for girls.

    2016-06-01

    The purpose of this study was to examine how sexual minority status (as assessed using both identity and behavior) was associated with trajectories of dating violence. University students from a large Southwestern university completed questions on their sexual minority identity, the gender of their sexual partners, and about experiences of dating violence for six consecutive semesters (N = 1942). Latent growth curve modeling indicated that generally, trajectories of dating violence were stable across study participation. Sexual minority identity was associated with higher initial levels of dating violence at baseline, but also with greater decreases in dating violence across time. These differences were mediated by number of sexual partners. Having same and other-sex sexual partners was associated with higher levels of dating violence at baseline, and persisted in being associated with higher levels over time. No significant gender difference was observed regarding trajectories of dating violence. PMID:26994347

    The present study examines the career trajectories of academic scientists during the period from 1993 to 2001 to explore gender differences in mobility. Data from the National Science Foundation's Survey of Doctorate Recipients are used to examine and compare gender differences in the odds of promotion. The effects of age, marital and family status, duration of time to complete doctorate, academic discipline, cumulative number of publications and time in the survey are considered as explanatory variables. Event history analyses are conducted for all scientists, for scientists in four major academic disciplines and for scientists in various academic ranks. While no overall gender differences were observed in the odds of promotion, several important similarities and differences were evident. Expectedly, publications had a significant and positive relationship with advancement for both women and men. The role of parent influenced promotions quite differently for women and men. Contrary to expectations based on prior research, academic women scientists who were mothers advanced at similar rates as women without children. Consistent with expectations based on traditional roles, married men and men with children generally advanced more quickly than single or childless men, respectively. Two surprising patterns emerged among subgroups of women. Marriage was associated with greater odds of advancement for women engineers and motherhood was associated with greater odds of advancement for among assistant professors. Possible explanations for these findings are presented.

    Gender and age have been found to affect adults’ audio-visual (AV) speech perception. However, research on adult aging focuses on adults over 60 years, who have an increasing likelihood for cognitive and sensory decline, which may confound positive effects of age-related AV-experience and its interaction with gender. Observed age and gender differences in AV speech perception may also depend on measurement sensitivity and AV task difficulty. Consequently both AV benefit and visual influence were used to measure visual contribution for gender-balanced groups of young (20–30 years) and middle-aged adults (50–60 years) with task difficulty varied using AV syllables from different talkers in alternative auditory backgrounds. Females had better speech-reading performance than males. Whereas no gender differences in AV benefit or visual influence were observed for young adults, visually influenced responses were significantly greater for middle-aged females than middle-aged males. That speech-reading performance did not influence AV benefit may be explained by visual speech extraction and AV integration constituting independent abilities. Contrastingly, the gender difference in visually influenced responses in middle adulthood may reflect an experience-related shift in females’ general AV perceptual strategy. Although young females’ speech-reading proficiency may not readily contribute to greater visual influence, between young and middle-adulthood recurrent confirmation of the contribution of visual cues induced by speech-reading proficiency may gradually shift females AV perceptual strategy toward more visually dominated responses.

    Purpose Hypertension is a major risk factor for the development of cardiovascular disease, stroke and end-organ damage. There is a sex difference in blood pressure (BP) that begins in adolescence and continues into adulthood, where men have a higher prevalence of hypertension compared to women until the sixth decade of life. Less than 50% of hypertensive adults in the United States taking medication manage to control their BP to recommended levels using current therapeutic options, and women are more likely than men to have uncontrolled high BP. This is despite the fact that more women compared to men are aware that they have hypertension and women are more likely to seek treatment for the disease. Novel therapeutic targets need to be identified in both sexes to increase the percentage of hypertensive individuals with controlled BP. The purpose of this article is to review the available literature on the role of T cells in BP control in both sexes, and the potential therapeutic application/implications of targeting immune cells in hypertension. Methods A search of PUBMED was conducted to determine the impact of sex and gender on T cell-mediated control of BP. The search terms included sex, gender, estrogen, testosterone, inflammation, T cells, T regulatory cells, Th17 cells, hypertension and blood pressure. Additional data were included from our laboratory examining cytokine expression in the kidney of male and female SHR and differential genes expression in both the renal cortex and mesenteric arterial bed of male and female SHR. Findings There is a growing basic science literature regarding the role of T cells in the pathogenesis of hypertension and BP control, however, the majority of this literature has been performed exclusively in males despite the fact that both men and women develop hypertension. There is increasing evidence that while T cells also mediate BP in females, there are distinct differences in both the T cell profile and the functional impact of “male” vs. “female” T cells on cardiovascular health, although more work is needed to better define the relative impact of different T cell subtypes on BP in both sexes. Implications The challenge now is to fully understand the molecular mechanisms by which the immune system regulates BP and how the different components of the immune system interact so that specific mechanisms can be targeted therapeutically without compromising natural immune defenses.

    With rapid population aging, increasing attention is given to the mental health of older people. This study examined the association between SES and depressive symptoms in older adults. The study population consisted of a representative community sample of 4165 persons aged 65 and older from Wave 1 of the Korean Longitudinal Study of Aging. The Center for Epidemiologic Studies Depression scale was used to measure the extent of depressive symptoms. Socioeconomic indicators included education, household income, and net worth. Analyses were conducted by gender, using multiple linear regression analysis, to identify independent effects of socioeconomic variables on depressive symptoms, controlling for demographics and health-related variables. There was an inverse association between higher levels of socioeconomic factors and depressive symptoms in the study population. A clear difference in the association between depressive symptoms and socioeconomic factors by gender was observed. In the multivariate analysis, wealth was significantly associated with depressive symptoms in men, whereas education and income was so in women. Gender disparities in depressive symptoms across social gradients suggest the need for gender-sensitive investments in health and social services for the disadvantaged segments of the older population.

    The authors examined concentrations of lead, cadmium, mercury, manganese, selenium, and chromium in feathers, liver, kidney, heart, and muscle of known-aged laughing gulls (Larus atricilla) that hatched in Barnegat Bay, New Jersey and were collected at John F. Kennedy International Airport, New York 1 to 7 years later. Concentrations differed significantly among tissues, and tissue entered all the regression models explaining the greatest variation in metal levels. Age of bird contributed significantly to the models for lead, cadmium, selenium, and chromium. Although there were significant gender differences in all body measurements except wing length, there were few differences in metal levels. Males had significantly higher lead levels in feathers, and females had significantly higher selenium levels in heart and muscle tissue. For lead, 3-year olds had the highest levels in the heart, liver, and kidney, and levels were lower thereafter. Mercury levels in feathers and heart decreased significantly with age. Cadmium levels increased significantly with age for feathers, heart, liver, and muscle, although there was a slight decrease in the 7-year olds. Selenium levels decreased significantly with age for all tissues. Chromium levels increased with age for liver and heart.

    Differences between males and females in the nature of their verbal communication have been documented. The findings of this study have provided a new dimensional to those of previous research. There is support for the idea that among college graduates with similar communication skills, females use written communication as a means of establishing rapport more than males. In a voluntary, relatively unstructured task, females tend to write longer responses and to express themselves by complete thoughts (sentences). Females are also more likely to use first person singular pronouns and first person singular possessive adjectives. There is no support in this situation for gender differences in offering solutions to described program weaknesses. The length of the open-ended responses describing weaknesses and strengths are more closely related to each other than they are to ratings of program satisfaction. This study was unique in that it was based on written communication of college graduates in a voluntary task. Differences in findings from of those of other studies may be due to experience and education of the participants. 7 refs., 2 tabs.

    According to embodied emotion theory, facial manipulations should modulate and initiate particular emotions. However, whether there are gender differences in emotion experience perception under different facial muscle manipulations is not clear. Therefore, we conducted two behavioral experiments to examine gender differences in emotional perception in response to facial expressions (sad, neutral, and happy) under three conditions: (1) holding a pen using only the teeth (HPT), which facilitates the muscles typically associated with smiling; (2) holding a pen using only the lips (HPL), which inhibits the muscles typically associated with smiling; and (3) a control condition - hold no pen (HNP). We found that HPT made the emotional feelings more positive, and that the change degree of female's ratings of sad facial expressions between conditions (HPL to HPT) was larger than males'. These results suggested cognition can be affected by the interaction of the stimuli and the body, especially the female. PMID:26845450

    Two experiments were conducted to examine the role of item type in mental rotation. In each experiment, participants completed two computerized mental rotation tasks, one with blocks as stimuli and one with human figures as stimuli. The tasks were formatted either as a multiple-choice psychometric test (Experiment 1) or as a same-different type task (Experiment 2). Aside from the expected replication of a decreased effect of occlusion on women's accuracy when processing human figures compared to block figures, it was hypothesized that response times would increase when processing the complex but familiar human figures, compared to the simple but unfamiliar block figures. In Experiment 1, the results relevant to occlusion were replicated. However, the presence of a speed-accuracy trade-off suggested that participants processed human figures faster but less accurately than block figures. In Experiment 2, both men and women performed faster and more accurately when processing occluded human figures than when processing nonoccluded human figures. The effect of item type, its potential link to embodied cognition, and the role of strategy selection on gender differences in mental rotation are discussed. PMID:26325234

    The present study used Model-Based Cluster analysis to identify primary and secondary psychopathy variants in a mixed-gender sample of 150 adjudicated adolescents (60 % male; M = 15.2 years old). Distinct primary and secondary psychopathy groups emerged and were entered into a structural equation path model for the purpose of predicting group differences in emotional experiences reported between youth assigned to each variant. Youth characterized by secondary psychopathy reported experiencing significantly more frequent and more intense negative affect than their primary psychopathy counterparts. Frequency and intensity of affect also mediated the association between psychopathy variants and symptoms of depression, in which the secondary psychopathy group endorsed significantly more symptoms of major depression than the primary psychopathy group. Overall, these results suggest that different causal processes and affective experiences may underlie distinct trajectories to primary and secondary psychopathy variants in adjudicated adolescents. As such, youths comprising the secondary subtype of psychopathy may be more aptly considered "callous and emotional," compared with the primary subtype who present as prototypically callous and unemotional.

    This paper proposes a gender classification based on human gait features and investigates the problem of two variations: clothing (wearing coats) and carrying bag condition as addition to the normal gait sequence. The feature vectors in the proposed system are constructed after applying wavelet transform. Three different sets of feature are proposed in this method. First, Spatio-temporal distance that is dealing with the distance of different parts of the human body (like feet, knees, hand, Human Height and shoulder) during one gait cycle. The second and third feature sets are constructed from approximation and non-approximation coefficient of human body respectively. To extract these two sets of feature we divided the human body into two parts, upper and lower body part, based on the golden ratio proportion. In this paper, we have adopted a statistical method for constructing the feature vector from the above sets. The dimension of the constructed feature vector is reduced based on the Fisher score as a feature selection method to optimize their discriminating significance. Finally k-Nearest Neighbor is applied as a classification method. Experimental results demonstrate that our approach is providing more realistic scenario and relatively better performance compared with the existing approaches.

    Obstructive sleep apnea (OSA) is an independent risk factor for cardiovascular diseases such as systemic arterial hypertension, ischemic heart disease, stroke, heart failure, atrial fibrillation, and cardiac sudden death. The pathogenesis of cardiovascular disease in OSA is thought to be induced primarily by chronic intermittent hypoxia (CIH), a specific pattern of change in oxygenation during sleep. However, the underlying mechanisms of CIH-induced vasculature injury and gender differences are not well documented. The iTRAQ Quantitative Proteomic method enables analysis of a number of different proteins among several groups. Thus, we explored gender differences in protein expression in the vascular walls of mice exposed to CIH. C57BL/6J mice of each gender were exposed to CIH with a fractional inspired O2 (FiO2) nadir of 5% or control, with a treatment time of 8 h/day for 28 days. Differential proteins related to CIH-induced vascular injury between genders were identified using iTRAQ proteomic technology. A total of 163 proteins were identified, of which 34 showed significant differences between genders, which may correlate with vascular injury by CIH. Twenty up-regulated proteins and 14 downregulated proteins were observed in female mice compared with male mice. We identified different vascular proteins expressed under CIH between genders, suggesting that these proteins may be biomarkers of vascular injury by CIH. PMID:25366743

    Objectives Growing evidence suggests that gender-blind assessment of exposure may introduce exposure misclassification, but few studies have characterized gender differences across occupations and industries. We pooled control responses to job-, industry-, 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. Methods 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 Chi-square and Mann-Whitney U-tests, respectively. Results The 1,360 female and 2,245 male controls reported 6,033 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. Conclusions 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. PMID:24683012

    Disruptive behaviour disorders are much more common in boys than girls (Office of National Statistics, 1999); in contrast, gender differences in normative problem behaviours are poorly understood. To address this issue, 228 6-year-olds (134 boys, 94 girls) were each observed playing a board game with a same-gender friend. Ratings of aggression, disruption, arousal and negativity were used to index problem behaviours. Multiple-groups confirmatory factor analyses demonstrated that the latent factor had the same metric for boys and girls, but a mean that was approximately half a standard deviation higher for boys than girls. In addition, the association between the latent factor and teachers' ratings of total difficulties was significantly stronger for boys than girls. PMID:21592147

    According to the power-control theory, growing independence of adolescent girls, manifest in more prevalent problem behaviors, may be explained by changes in family structure (increasing level of authority gained in the workplace by mothers). To verify this hypothesis, self-report data from Warsaw adolescents (N = 3087, age 14-15 years, 50% boys) were used. Results indicate that parenting practices differ across child gender and structure of parents' work authority. Girls, especially in patriarchal households, spend more time with mothers and perceive stronger maternal control. In egalitarian families, fathers tend to be more involved with sons than with daughters. When parental control, support and adolescents' risk preferences are controlled, the gender-by-household type interaction effect is observed--girls in patriarchal families have the lowest risk of getting drunk. Study results provide support for power-control theory showing the relationship between parental work authority and adolescent's heavy alcohol use. PMID:20513655

  19. On difference and capital: gender and the globalization of production.

    PubMed

    Bair, Jennifer

    2010-01-01

    This article is both a review of, and an intervention in, the literature on gender and the globalization of production. Via a discussion of six key texts analyzing export-oriented manufacturing, ranging from Maria Mies's Lace Makers of Narsapur to Melissa Wright's Disposable Women and Other Myths of Global Capitalism, I show that, over time, the focus has shifted from an emphasis on the feminization of manufacturing as a defining feature of globalization to an appreciation of the diverse and contingent ways in which gender matters for offshore production. While this recent scholarship highlights variability in gendered labor regimes at the global-local nexus, I argue that it is also critically important to ask what is similar about the many locations on the global assembly line that have been studied. Specifically, we must look to how gender, as a set of context-specific meanings and practices, works within the macrostructure of the global economy and its systemic logic of capital accumulation. In other words, while capitalism does not determine the concrete modalities of gender that exist in a given locale, it is essential for explaining the gendered dimension of transnational production as a patterned regularity of contemporary globalization.

    The aim of this study was to determine the prevalence of bullying in its various forms from the perspective of all of the individuals involved (victims, bullies, and witnesses) and to explore its distribution as a function of gender. The study had a correlational design and used a representative sample of 1500 Spanish students attending compulsory secondary education in the academic year 2007-2008. It applied an instrument measuring different types of bullying, taken from the studies conducted by Díaz-Aguado, Martínez, and Martín (2004) and the Defensor del Pueblo (Spanish Ombudsman's Office)-UNICEF (2007). The findings reveal that all the types of bullying considered take place at school and that there is an inverse relationship between the severity and the prevalence of bullying behaviors, with verbal abuse proving to be the most common type of abusive behavior. Boys are involved in all kinds of bullying incidents as bullies significantly more often than girls are, except in cases involving 'talking about someone behind their back'; in these situations, girls are involved significantly more often as bullies than boys are. As for victimization, boys are victims of direct physical abuse significantly more often than girls are, while girls are more often the subject of malicious gossip. PMID:23866215

    Recently it has been reported that women do not have the capacity to accumulate supranormal levels of muscle glycogen when subjected to a carbohydrate (CHO) loading regimen [Tarnopolsky et al. (1995) J Appl Physiol 78:1360-1368]. Since, in this study, CHO intake relative to body mass in the female subjects was much lower than that in males, our primary aim was to re-examine this issue using subjects fed comparable amounts of CHO. Endurance-trained female and male subjects ingested 12 g CHO x kg(-1) lean body mass day(-1) in conjunction with the cessation of their daily physical training. A 3-day exposure to this diet resulted in a marked rise in muscle glycogen levels from [mean (SD)] 108 (15) mmol x kg(-1) wet weight to 193 (14) mmol x kg(-1) wet weight and 111 (16) m mol x kg(-1) wet weight to 202 (20) mmol x kg(-1) wet weight in the female participants during the post-menstrual and pre-menstrual phases of their menstrual cycle, respectively, and from 109 (27) mmol x kg(-1) wet weight to 183 (25) mmol x kg(-1) wet weight in males. We conclude that (1) female athletes have the capacity to accumulate supranormal levels of muscle glycogen, and (2) when exercise-trained males and females are fed comparable amounts of CHO relative to lean body mass, there is no gender-related difference in their ability to accumulate supranormal levels of muscle glycogen.

    A sample of 158 male and 357 female college students at a midwestern university participated in an on-line study of psychosocial motives for texting while driving. Men and women did not differ in self-reported ratings of how often they texted while driving. However, more women sent texts of less than a sentence while more men sent texts of 1-5 sentences. More women than men said they would quit texting while driving due to police warnings, receiving information about texting dangers, being shown graphic pictures of texting accidents, and being in a car accident. A hierarchical regression for men's data revealed that lower levels of feeling distracted by texting while driving (20% of the variance), higher levels of cell phone dependence (11.5% of the variance), risky behavioral tendencies (6.5% of the variance) and impulsivity (2.3%) of the variance) were significantly associated with more texting while driving (total model variance=42%). A separate regression for women revealed that higher levels of cell phone dependence (10.4% of the variance), risky behavioral tendencies (9.9% of the variance), texting distractibility (6.2%), crash risk estimates (2.2% of the variance) and driving confidence (1.3% of the variance) were significantly associated with more texting while driving (total model variance=31%.) Friendship potential and need for intimacy were not related to men's or women's texting while driving. Implications of the results for gender-specific prevention strategies are discussed.

    Faces represent valuable signals for social cognition and non-verbal communication. A wealth of research indicates that women tend to excel in recognition of facial expressions. However, it remains unclear whether females are better tuned to faces. We presented healthy adult females and males with a set of newly created food-plate images resembling faces (slightly bordering on the Giuseppe Arcimboldo style). In a spontaneous recognition task, participants were shown a set of images in a predetermined order from the least to most resembling a face. Females not only more readily recognized the images as a face (they reported resembling a face on images, on which males still did not), but gave on overall more face responses. The findings are discussed in the light of gender differences in deficient face perception. As most neuropsychiatric, neurodevelopmental and psychosomatic disorders characterized by social brain abnormalities are sex specific, the task may serve as a valuable tool for uncovering impairments in visual face processing.

    Background Gender differences in the relationship between alcohol use and depressive symptoms are inconsistent, and few studies have addressed this issue in Russia. Because this finding may have important implications for interventions to reduce alcohol misuse or alcohol related problems in Russia, we conducted a study to investigate whether the association between alcohol use and depressive symptoms differs by gender at high risk for HIV. Methods We used the Alcohol Use Disorders Identification Test (AUDIT) and the 10-item Center for Epidemiological Studies Depression Scale to measure alcohol use and depressive symptoms among 307 patients who attended a clinic for sexually transmitted infections in St. Petersburg, Russia. Logistic regression models were applied for the analysis. Results The comparison of data between men and women revealed a significant quadratic term of alcohol use and significant interactions between alcohol use and gender on depressive symptoms. Men with an AUDIT score in the first and fourth quartiles were more likely to report depressive symptoms in comparison to men in the second quartile. Their odds ratios (ORs) and 95% confidence intervals (CIs) were 7.54 (2.00–28.51) and 5.06 (1.31–19.63), respectively. Among women, a linear trend was observed such that those who misused alcohol were three times more likely to have depressive symptoms than those who did not misuse alcohol (OR = 3.03, 95% CI, 1.05–8.80). Conclusion The association between alcohol use and depressive symptoms differed by gender. Additional research is needed to investigate this relationship in Russia. Strategies to reduce alcohol-related problems in Russia may need to consider these differences. PMID:23240098

    This multi-national study hypothesized that higher levels of country-level gender equality would predict smaller differences in the frequency of women's compared to men's drinking in public (like bars and restaurants) settings and possibly private (home or party) settings. GENACIS project survey data with drinking contexts included 22 countries in Europe (8); the Americas (7); Asia (3); Australasia (2), and Africa (2), analyzed using hierarchical linear models (individuals nested within country). Age, gender and marital status were individual predictors; country-level gender equality as well as equality in economic participation, education, and political participation, and reproductive autonomy and context of violence against women measures were country-level variables. In separate models, more reproductive autonomy, economic participation, and educational attainment and less violence against women predicted smaller differences in drinking in public settings. Once controlling for country-level economic status, only equality in economic participation predicted the size of the gender difference. Most country-level variables did not explain the gender difference in frequency of drinking in private settings. Where gender equality predicted this difference, the direction of the findings was opposite from the direction in public settings, with more equality predicting a larger gender difference, although this relationship was no longer significant after controlling for country-level economic status. Findings suggest that country-level gender equality may influence gender differences in drinking. However, the effects of gender equality on drinking may depend on the specific alcohol measure, in this case drinking context, as well as on the aspect of gender equality considered. Similar studies that use only global measures of gender equality may miss key relationships. We consider potential implications for alcohol related consequences, policy and public health.

    In unstationary swimming (changing velocity), some of the water around the swimmer is set in motion. This can be thought of as an added mass (M(a)) of water. The purpose of this study was to find added mass on human swimmers and investigate the effect of shape and body size. Thirty subjects were connected to a 2.8m long bar with handles, attached with springs (stiffness k = 318 N/m) and a force cell. By oscillating this system vertically and registering the period of oscillations it was possible to find the added mass of the swimmer, given the known masses of the bar and swimmer. Relative added mass (M(a)%) for boys, women and men were, respectively, 26.8 +/- 2.9%, 23.6 +/- 1.6% and 26.8 +/- 2.3% of the subjects total mass. This study reported significantly lower added mass (p < 0.001) and relative added mass (p < 0.002) for women compared to men, which indicate that the possible body shape differences between genders may be an important factor for determining added mass. Boys had significantly lower (p < 0.001) added mass than men. When added mass was scaled for body size there were no significant differences (p = 0.996) between boys and men, which indicated that body size is an important factor that influences added mass. The added mass in this study seems to be lower and within a smaller range than previously reported (Klauck, 1999; Eik et al., 2008). It is concluded that the added mass in human swimmers, in extended gliding position, is approximately 1/4 of the subjects' body mass. PMID:20546755

  9. Are There Gender Differences in Arrest Trajectories among Adult Drug Abuse Treatment Participants?

    2010-12-01

    This paper examines the arrest trajectories of adult men and women, drawn from a sample of clients admitted to substance abuse treatment. Growth-mixture modeling was used to identify distinctive trajectories in arrests for men and women between ages 18 and 45. In addition, the characteristics of men and women in each of the trajectory groups were compared by gender, arrest trajectory, and the interaction of gender and arrest trajectory. Findings indicated that while the shape of the five trajectories was similar for men and women, higher percentages of men than women were in the High trajectory group (12.5% vs. 8.5%), the Moderate group (27.9% vs. 20.9%), and Slow Increase group (25.5% vs. 20.6%), with more women than men being in the Low group (34.1% vs. 27.1%). Although arrests declined as men and women aged, there did not appear to be many individuals who had terminated their criminal career by age 45. Overall, more similarities than differences were observed in the characteristics of men and women across trajectories. Additional research should examine whether the causal factors influencing arrest trajectories differ by gender. PMID:21052519

    This article examines prevalence and gender differences of alcohol use and risk drinking in a representative sample of Ontario adults. Data were drawn from the Centre for Addiction and Mental Health (CAMH) Monitor survey of Ontario adults aged 18 and older collected between January 2005 and December 2010. The prevalence of self-reported lifetime, current, and high-risk drinking were all higher among the Canadian and the European-origin groups compared with other ethnic groups. Within-group gender differences were evident for all ethnic groups. The narrowest gender gap was observed within the North European group and the widest in the South Asian group. The non-European ethnic groups had higher rates of abstinence and lower alcohol consumption rates; nevertheless, a considerable proportion of people from these groups may be at risk of alcohol-related harm due to risky and harmful alcohol consumption patterns. Future research should continue to investigate alcohol use in these groups and identify subgroups at risk and factors that increase or decrease their vulnerability to risky and problem drinking.

    Compared with the general population, an excess of rare copy number variants (CNVs) has been identified in people with schizophrenia. Females with neurodevelopmental disorders and in the general population have been reported to carry more large, rare CNVs than males. Given that many schizophrenia datasets do not have equal gender ratios in cases and controls, sex differences in CNV burden might have impacted on estimates of case-related CNV burden and also on associations to individual loci. In a sample of 13,276 cases and 17,863 controls, we observed a small but significant excess of large (≥500 Kb), rare (<1%) CNVs in females compared with males in both cases and controls (OR = 1.17, P = 0.0012 for controls; OR = 1.11, P = 0.045 for cases). The burden of 11 schizophrenia-associated CNVs was significantly higher in female cases compared with male cases (OR = 1.38, P = 0.0055), but after accounting for the rates of CNVs in controls, we found no significant gender difference in the risk conferred by these loci. Controlling for gender had a negligible effect on the significance of association between specific CNVs and schizophrenia. The female excess of large CNVs in both cases and controls suggests a female protective mechanism exists for deleterious CNVs that may extend beyond neurodevelopmental phenotypes. PMID:27185616

    Age at illness onset has significant clinical implications for psychiatric disorders. Prior research has not systematically examined age at illness onset and its relationship to the clinical characteristics of pathological gambling (PG). Among a sample of 322 consecutive subjects with current DSM-IV PG, those with late-onset (at or after age 55 years) PG were compared to those with earlier onsets (at or prior to age 25, 26-54 years old) on measures of PG severity, co-occurring disorders, social and legal problems, and family history. Forty-two (13.4%) subjects reported onset of PG at or after age 55 years, 63 (19.6%) reported onset prior to age 25 years, and the majority (n=217; 67.4%) reported onset between the ages of 26 and 54 years. The late-onset group were less likely to declare bankruptcy (p=.029) or have credit card debt attributable to gambling (p=.006). Late-onset PG subjects were significantly more likely to have an anxiety disorder (p<.001) and significantly less likely to have a father (p=.025) or a mother (p=.048) with a gambling problem. Exploratory analyses identified an age-by-gender interaction with respect to treatment-seeking, with more pronounced age-related shortening in the duration between problem onset and treatment seeking observed in men. Age at onset of PG is associated with multiple important clinical features. Long durations of PG prior to treatment-seeking indicate the need for improved prevention efforts among individuals with early PG onset. Late-onset PG is relatively common and has distinct clinical characteristics suggesting that this population might benefit from unique prevention and treatment strategies. PMID:18499125
