Sample records for male gender age

  1. Age, gender and deterrability: Are younger male drivers more likely to discount the future?

    Freeman, James; Kaye, Sherrie-Anne; Truelove, Verity; Davey, Jeremy

    2017-07-01

    Utilizing the Classical Deterrence theory and Stafford and Warr's (1993) reconceptualized model of deterrence, the current study examined whether age, gender, and discounting the future tendencies influence perceptions of being apprehended for speeding offences. Licensed motorists (N=700; 57% female) in Queensland (Australia) were recruited to complete a self-report questionnaire that measured perceptual deterrence, speeding related behaviors and discounting the future tendencies. Data were analyzed utilizing descriptive, bivariate and multivariate regressions. Significant (albeit weak) positive correlations were found between age and perceptions of apprehension certainty. Males were significantly more likely to report higher incidences of speeding (including while avoiding detection) compared to females. In contrast, females were more likely to perceive high levels of apprehension certainty and consider impending penalties to be more severe. At a multivariate level, discounting the future tendencies (in addition to being male, reporting lower levels of perceptual severity and swiftness, and more instances of punishment avoidance) were predictive of lower perceptual certainty levels. This study is one of the first to reveal that being male and having a tendency to discount the consequences of the future may directly influence drivers' perceptual deterrence levels.

  2. Gender-disturbed males.

    Levine, S B

    1993-01-01

    Adolescent and adult cross-dressing or "transvestism" is the most common antecedent behavioral pattern among those who request sex reassignment surgery. Transvestites are actually a diverse group of men who differ in their gender identities, orientation, and intention. They do, however, have in common a soothing image of themselves as women. Because of this, whether cross-dressing occurs among masculine or feminine males or heterosexuals, homosexuals, bisexuals, or asexuals, or among those with paraphilia, the behavior should be considered the expression of their consciously felt femininity. The confusing differences among cross-dressing males may be explained by their diversity along three dimensions: 1) the ambition for heterosexual intercourse; 2) the natural history of their sexual arousal to female clothing; 3) their current capacity to integrate their masculine and feminine strivings into separate compartments. When cross-dressers give up all vestiges of male gender role behaviors and successfully live and work full time as women, the appropriate descriptive term for them becomes "transsexual."

  3. Male gender preference, female gender disadvantage as risk factors for psychological morbidity in Pakistani women of childbearing age - a life course perspective

    Full Text Available Abstract Background In Pakistan, preference for boys over girls is deeply culturally embedded. From birth, many women experience gendered disadvantages; less access to scarce resources, poorer health care, higher child mortality, limited education, less employment outside of the home and circumscribed autonomy. The prevalence of psychological morbidity is exceptionally high among women. We hypothesise that, among women of childbearing age, gender disadvantage is an independent risk factor for psychological morbidity Methods A cross-sectional catchment area survey of 525 women aged 18 to 35 years living in Islamabad and Rawalpindi. The effect of gender disadvantage was assessed as a latent variable using structural equation modelling. Indicators were parental gender preference, low parental care, parental overprotection, limited education, early age at marriage, marital dissatisfaction and low autonomy. Psychological morbidity was assessed using the 20 item Self Reporting Questionnaire (SRQ. Results Gender disadvantage was independently predictive of psychological morbidity. Among married women, socio-economic status did not predict psychological morbidity, and the effect of education was mediated through gender disadvantage rather than socioeconomic status (SES. The women's own preference for a male child was strongly predicted by their perceptions of having been disadvantaged by their gender in their families of origin. Conclusions The high prevalence of psychological morbidity among women in Pakistan is concerning given recently reported strong associations with low birth weight and infant stunting. Social action, public policies and legislation are indicated to reduce culturally embedded preferences. Neglect of these fundamentals will entrench consequent inequities including gender bias in access to education, a key millennium development goal.

    Age- and gender-related alterations of hemorheological parameters have not been completely elucidated to date. Experiments on older animals may give valuable information on this issue. However, the majority of rheological studies have been performed in young rodents. We aimed to investigate the influence of aging and gender on hemorheological parameters in rats. Coeval male (n=10) and female (n=10) Wistar (Crl:WI) rats were followed-up over 15 months. Blood samples were obtained from the lateral tail vein at 3, 4, 5, 9, 12, 15 and 18 months of age. Hematological parameters, red blood cell deformability (elongation under shear), osmotic gradient deformability and erythrocyte aggregation were tested. Body weight and the estrus cycle (in females) were also examined. Erythrocyte aggregation showed age- and gender-related variations. Red blood cell deformability was greater in females and gradually decreased over the 15-month period in both genders. Erythrocyte aggregation was greater in male rats at most ages, but did not show consistent changes with age. The micro-rheological parameters showed age-related alterations with gender differences. The effect of the estrous cycle cannot be excluded in female rats. The results provide reference data for studies of aging in rats and of the mechanism related to age and gender differences in hemorheology.

  5. Only for Males: Gendered Perception of Wrestling

    2012-01-01

    Full Text Available Wrestling has generally been considered to be a masculine sport. To increase female participation in the sport, managers and administrators will need to understand how wrestling is perceived differently by the genders. A focus group interview was conducted with eight participants from both genders to examine how wrestling was perceived. The findings suggested that wrestling was regarded more as a form of violent entertainment rather than as a sport. A survey instrument was then constructed using statements made by the focus group. The survey was administered to 155 respondents of which 56% were females. The mean age of the respondents was 19.8 years. The findings from the survey concurred with the findings from the focus group interview. Wrestling is considered to be a violent and gendered form of entertainment. However, gender differences exist with females more likely to see wrestling as a form of entertainment as compared to males. Females are also more likely to view wrestling as violent and consequently, they tend to see wrestling as more suited for male participation. The findings suggest that sports managers and administrators will need to manage the perception that wrestling is a form of violent entertainment among females by creating opportunities for women to experience the sport and to correct their perception of the sport.

    alpha estradiol have been synthesized some of which show selectivity for the central nervous system. CNS effects have been demonstrated in female and male animals. Cardiovascular protection by estrogens has been shown in animal and human studies. Atherosclerotic plaque size was reduced after estrogen injections in cholesterol-fed rabbits. Phytoestrogen-fed monkeys had lower total cholesterol and LDL cholesterol and higher HDL cholesterol. Apart from atherosclerotic lesions, coronary artery vascular reactivity was improved. Some of these experimental findings were confirmed in human studies in postmenopausal women with and without estrogen treatment. Whether all of the described estrogenic effects can be seen in men remains to be investigated. (Med J Indones 2001; 10: 127-33Keywords : aging, andropause, testosterone, estrogens

    Ageing is a distinctly gendered phenomenon, women being increasingly represented in the older cohorts of the European population, due to their longer life expectancy than men. Furthermore, gender differences and inequalities are a fundamental feature of social exclusion and poverty in old age. The twofold discrimination against older women workers based on gender and age stereotypes, combined with their greater vulnerability in the labour market caused by women-specific work trajectories (i.e...

    The aim of this study was to investigate gender related differences in the management and risk factor control of patients with coronary heart disease (CHD), taking into account their age and educational level. Analyses are based on the EUROASPIRE IV (EUROpean Action on Secondary and Primary Prevention through Intervention to Reduce Events) survey. Males and females between 18 and 80years of age, hospitalized for a first or recurrent coronary event were included in the study. Data were available for 7998 patients of which 75.6% were males. Overall, females had a worse risk factor profile compared to males and were more likely to have 3 or more risk factors (29.5% vs. 34.9%; p<0.001) across all age groups. A significant gender by education interaction (p<0.05) and gender by age interaction effect (p<0.05) was found. Furthermore, males were more likely to have a LDL-cholesterol on target (OR=1.50[1.28-1.76]), a HbA1c on target (OR=1.33[1.07-1.64]), to be non-obese (OR=1.45[1.30-1.62]) and perform adequate physical activity (OR=1.71[1.46-2.00]). In contrast males were less likely to be non-smokers (OR=0.71[0.60-0.83]). Furthermore, males were less likely to have made a dietary change (OR=0.78[0.64-0.95]) or a smoking cessation attempt (OR=0.70[0.50-0.96]) and more likely to have received smoking cessation advice if they were smokers (OR=1.52[1.10-2.09]). Whereas gender differences in CHD treatment are limited, substantial differences were found regarding target achievement. The largest gender difference was seen in less educated and elderly patients. The gender gap declined with decreasing age and higher education. Copyright © 2016. Published by Elsevier Ireland Ltd.

  10. CEO age and gender: Subsequent market performance

    2016-12-01

    Full Text Available The issue of CEO age and gender vs. concurrent performance is extensively examined, but the association with subsequent performance has limited treatment in the financial literature, and with conflicting findings. In the current study, we examine the association between CEO age and gender, and subsequent company market performance using a more recent set of observations and the standard four-factor model to estimate future cumulative abnormal shareholder returns. We find that subsequent abnormal shareholder returns are marginally significantly higher for female CEOs than for their male counterparts, but no material pattern is observed between CEO age and subsequent abnormal shareholder return performance.

  15. Does Gender Matter? an Exploratory Study of Perspectives Across Genders, Age and Education

    Carinci, Sherrie; Wong, Pia Lindquist

    2009-11-01

    Using a convenience sample and survey research methods, the authors seek to better understand how perspectives on gender are shaped by individuals' age, level of education and gender. Study participants responded in writing to scenarios and survey questions, revealing their personal views on gender as an identity category and as a marker in the social hierarchy. Analysis indicated that there were differences between male and female views on these dimensions of gender, and that age and educational levels were also influential. While younger respondents from both genders demonstrated flexibility in their definitions of gender and expressed strong support for gender equality, they were noticeably lacking in their knowledge of the historical context of gender relations and did not show the skills required to realise their ideals of gender equality, especially when compared to older respondents of both genders with higher levels of educational attainment.

    Male gender preference is a dominant feature of Igbo culture and could be the reason behind women seeking fetal gender at ultrasound. The aim of this study is to investigate the perception of prenatal ultrasound patients of male gender preference in a patriarchal and gender sensitive society. The study was a cross-sectional survey, which targeted pregnant women who presented for prenatal ultrasound at four selected hospitals in Anambra State. A convenience sample size of 790 pregnant women constituted the respondents. The data collection instrument was a 13-item semi-structured self-completion questionnaire designed in line with the purpose of the study. Descriptive and inferential statistical analyses were carried out with statistical significance being considered at P < 0.05. Most of the women (88.4%, 698/790) were aware that fetal gender can be determined during the prenatal ultrasound while just over half of them (61.0%, 482/790) wanted fetal gender disclosed to them during prenatal ultrasound. More than half (58.6%, 463/790) of the women desired to have male babies in their present pregnancies while 20.1% (159/790) desired female babies and 21.3% (168/790) did not care if the baby was male or female. Some of the women (22.2%, 175/790) wanted to have male babies in their present pregnancies for various reasons predominant of which was protecting their marriages and cementing their places in their husbands' hearts. Male gender preference was strongly perceived. There was considerable anxiety associated with prenatal gender determination and moderate loss of interest in the pregnancy associated with disclosure of undesired fetal gender. Socio-demographic factors had significant influence on perception of male gender preference. Male gender preference is strongly perceived among Igbo women and its perception is significantly influenced by socio-demographic factors. Male gender preference may be responsible for Igbo women seeking fetal gender at ultrasound.

  20. GENDER AND AGE FEATURES OF GLAUCOMA

    O. V. Makarenk

    2014-02-01

    Full Text Available Today, the definition “glaucoma” combines a number of eye pathologies that lead to irreversible blindness, and therefore is difficult disabling disease. Glaucoma occurs in people of working age, so this problem is not only medical, but also social, because it causes disability in substantial economic costs not only for individual patients, but also for the whole country – patients become unable to work. Gender features of glaucoma are also contradictory. In European literature the basic idea is that men are more likely to suffer from glaucoma than women. Such studies have not been conducted in the Podillya region of Ukraine, that makes impossible to design a reliable global data to estimate the prevalence of glaucoma in different age groups for persons living in Vinnitsa region. Therefore, the aim of the study was a retrospective analysis of medical records of patients in Eye Microsurgery Department of Vinnitsa Regional Clinical Hospital for the period 2008-2012 years for determining the gender and age characteristics. Materials and methods 1418 patients with primary open-angle glaucoma (841 men and 577 women aged 14 to 92 years (mean age 67,12 ± 7,64, which were treated in the Eye Microsurgery Department, took part in the study. For the purpose of the study they were divided into two groups: I – male patients with glaucoma, II – female patients with glaucoma. Each group was divided into 7 subgroups according to the ontogenesis scheme: A – teens, B – youth, C – I adulthood age, D – II adulthood age, E – elderly age, F – senily age and G – centenarians. Thus was allocated 12 research groups. Results The structure of the incidence of glaucoma is 59.31% in men and 40.69% in women. Incidence of glaucoma is highest in the IE group and is 34.98%. The group IIE incidence is lower – 35.32%. In the group D the incidence of glaucoma among men and women was very different (13.89% and 2.89%, respectively. It should also be noted

  1. Aging in the Male Face: Intrinsic and Extrinsic Factors.

    Keaney, Terrence C

    2016-07-01

    Gender is one of the most significant factors that influence facial anatomy and behavior, both key factors in the aging process. To review male facial anatomy, physiology, and behavior and how it contributes to sexual dimorphism in facial aging. A MEDLINE search was performed for publications on gender differences in facial anatomy, aging, cutaneous physiology, and behavior. There are differences in both intrinsic and extrinsic aging factors in men. Men have a thicker epidermis and dermis with more active cutaneous appendages including hair growth. Male skin has a reduced antioxidant capacity and increased ultraviolet-induced immunosuppression. The male face is larger and has a unique square shape with less subcutaneous soft tissue, especially at the medial cheek. Men are also more prone to smoking and exhibiting poor sun-protective behavior. The differences in intrinsic and extrinsic aging factors contribute to poor facial aging in men. Men develop more severe rhytides in a unique pattern, show increased periocular aging changes, and are more prone to hair loss. This review provides insight into the factors contributing to accelerated male facial aging. Understanding gender differences in aging will help physicians tailor cosmetic treatments for men and minimize extrinsic aging factors.

  2. Gender-Atypical Mental Illness as Male Gender Threat.

    Michniewicz, Kenneth S; Bosson, Jennifer K; Lenes, Joshua G; Chen, Jason I

    2016-07-01

    The present study examined whether men view gender-atypical (i.e., feminine) psychological disorders as threats to their gender status. Men and women (N = 355) rated their expectations of gender status loss, feelings of distress, and help-seeking intentions in response to 10 different stereotypically masculine and feminine psychological disorders. Men as compared to women expected greater gender status loss for, and reported more distress to, gender-atypical versus gender-typical disorders. Expectations of gender status loss partially mediated the link between participant gender and distress at the thought of gender-atypical disorders. These findings suggest that feminine disorders pose more powerful gender status threats for men than masculine disorders do and that men's expectations of gender status loss for feminine disorders drive their negative reactions to these mental illnesses. The discussion emphasizes the importance of considering the gender-typicality of disorders, and the implications of these findings for clinical interventions. © The Author(s) 2015.

  3. Gender, aging, health and society.

    Dhar, H L

    2001-10-01

    There are more women than men at any elderly age group. Depression and osteoporosis are the commonest problems in elderly subjects. Some problems specific to males are hypogonadism, erectile dysfunction and enlargement of prostrate and to females are post-menopausal disturbances, urinary incontinence and breast and lung cancer. However, problems of special concern in both male and female elderly are malnutrition, falls and cognitive dysfunction. Men and women in general suffer from the same sorts of health problems but the frequency of these problems as well as the speed of the onset of death distinguishes them. Infact cultural and social forces act to separate the sexes in their personal health ethos and their sick propensity. The impact of old age on women is different from that of men because of differences in their status and role in society. This is specially so because proportion of widows in 60+ age group is considerably higher than that of widowers. Sexuality is often overlooked as a health status particularly in elderly women. Clinicians should recognise the importance of sexual functions to the overall health of older persons particularly women. Religious participation and involvement are associated with positive mental and physical health. Family life is the key to the health of elders specially older men. Lack of social support increases the risk of mortality and supportive relationships are associated with lower illness rates, faster recovery rates and higher levels of health care behavior.

Este trabalho tem o objetivo de mensurar a existência de preconceitos nas manifestações dos estereótipos de gênero e sexismo ambivalente, em adolescentes masculinos de 12 a 16 anos. Em um estudo transversal, aplicaram-se três questionários (sociodemográfico, Gender stereotyping, Inventário do Sexismo Ambivalente a 787 estudantes de 11 escolas públicas. Nos resultados, detectou-se a presença de estereótipos de gênero. Houve diferença significante entre alunos de escolas estaduais e municipais e também nos alunos que estudavam em bairros de poder aquisitivo elevado em relação aos demais. O sexismo, também presente, apresentou-se significantemente mais benévolo que hostil. O escore para o componente benévolo variou conforme a escola cursada. O hostil não foi influenciado pelas variáveis estudadas. Os achados corroboram a existência de estereótipos de gênero e sexismo ambivalente nos adolescentes masculinos e a necessidade de desenvolvimento de ações e políticas para sua erradicação.Discrimination and violence against the female gender are associated with distorted representation of women.

    Sanderson, W.; Scherbov, S.

    2017-01-01

    Gender gaps are typically measured by subtracting the survival rates for women from that of men. In most countries and at most ages, these gender gaps indicate a survival rate disadvantage for men. This method is not informative because it is unclear whether larger or smaller gaps would be more equitable. Here we reconceptualize the gender gap in survival based on differences from gender-specific best practice rates and express those gender gaps in the metric years of age. If the age-specific...

  6. The influence of gender and gender typicality on autobiographical memory across event types and age groups.

    Grysman, Azriel; Fivush, Robyn; Merrill, Natalie A; Graci, Matthew

    2016-08-01

    Gender differences in autobiographical memory emerge in some data collection paradigms and not others. The present study included an extensive analysis of gender differences in autobiographical narratives. Data were collected from 196 participants, evenly split by gender and by age group (emerging adults, ages 18-29, and young adults, ages 30-40). Each participant reported four narratives, including an event that had occurred in the last 2 years, a high point, a low point, and a self-defining memory. Additionally, all participants completed self-report measures of masculine and feminine gender typicality. The narratives were coded along six dimensions-namely coherence, connectedness, agency, affect, factual elaboration, and interpretive elaboration. The results indicated that females expressed more affect, connection, and factual elaboration than males across all narratives, and that feminine typicality predicted increased connectedness in narratives. Masculine typicality predicted higher agency, lower connectedness, and lower affect, but only for some narratives and not others. These findings support an approach that views autobiographical reminiscing as a feminine-typed activity and that identifies gender differences as being linked to categorical gender, but also to one's feminine gender typicality, whereas the influences of masculine gender typicality were more context-dependent. We suggest that implicit gendered socialization and more explicit gender typicality each contribute to gendered autobiographies.

  8. Toward a gender politics of aging.

    Carney, Gemma M

    2018-01-01

    The article proposes a Gender Politics of Aging approach to the study of aging societies. The approach recognizes the feminization of old age, ageism's roots in sexist discourse, and the need to recognize the role of politics in driving demographic debates. Drawing together arguments from feminist gerontology and political demography, the article argues that the intersection of politics and gender must be considered if appropriate responses to an older, feminized demography are to be produced. I conclude that the work of aging feminists provides a rich vein of research and praxis from which a gender politics of aging approach can draw.

    The effect of parental rearing on gender identity development in children with ambiguous genitalia remains controversial. The present study aimed to address this issue by investigating the factors that may be associated with sex of rearing in children with male pseudohermaphroditism. The study included 56 children with male pseudohermaphroditism that were consecutively referred to a child psychiatry outpatient clinic. At the time of referral the age range of the sample was 6 months-14 years; 28 children had been raised as boys and 28 as girls. Demographic and biological information was obtained from patient charts. An intersex history interview was administered to the children and parents, whereas The Gender Identity Interview and the Draw-A-Person Test were administered only to the children. The children were observed during free play. Comparisons of biological, psychological and social variables were made with respect to gender of rearing. More children reared as boys were younger at time of referral, belonged to extended families, and had higher Prader scores. Although children's gender roles were appropriate for their gender of rearing, findings of the Gender Identity Interview and the Draw-A-Person Test suggested that some of the girls presented with a male or neutral gender self-perception. The relationships between age at the time of problem identification, age at the time of diagnosis, and gender of rearing indicate the importance of taking measures to ensure that the intersex condition is identified at birth and children are referred for early diagnosis, gender assignment, and treatment.

    This study investigated the participation and performance trends as well as the age and gender interaction at the Olympic distance 'Zürich Triathlon' (1.5 km swim, 40 km cycle and 10 km run) from 2000 to 2010 in 7,939 total finishers (1,666 females and 6,273 males). Female triathletes aged from 40 to 54 years significantly (P distance triathlon performance increased after the age of 35 years, which appeared earlier compared to long distance triathlon as suggested by previous studies. Future investigations should compare gender difference in performance for different endurance events across age to confirm a possible effect of exercise duration on gender difference with advancing age.

  13. Gender effects on age-related changes in brain structure.

    2000-01-01

    Previous reports have suggested that brain atrophy is associated with aging and that there are gender differences in brain atrophy with aging. These reports, however, neither exclude silent brain lesions in "healthy subjects" nor divide the brain into subregions. The aim of this study is to clarify the effect of gender on age-related changes in brain subregions by MR imaging. A computer-assisted system was used to calculate the brain matter area index (BMAI) of various regions of the brain from MR imaging of 331 subjects without brain lesions. There was significantly more brain atrophy with aging in the posterior parts of the right frontal lobe in male subjects than there was in female subjects. Age-related atrophy in the middle part of the right temporal lobe, the left basal ganglia, the parietal lobe, and the cerebellum also was found in male subjects, but not in female subjects. In the temporal lobe, thalamus, parieto-occipital lobe, and cerebellum, brain volume in the left hemisphere is significantly smaller than in the right hemisphere; sex and age did not affect the hemisphere differences of brain volume in these regions. The effect of gender on brain atrophy with aging varied in different subregions of the brain. There was more brain atrophy with aging in male subjects than in female subjects.

  16. The aging population: imperative to uncouple sex and gender to establish "gender equal" health care.

    Bachmann, Gloria A; Mussman, Brianna

    2015-04-01

    The transgender community has long been marginalized in society. As the world's population ages, gender-unbiased health services for this growing population, with age-related chronic illnesses, will be essential. To optimally eliminate hurdles that trans individuals often confront when requesting services, it appears judicious to eliminate the strict and antiquated definition of what constitutes "normal" female and "normal" male. A review of literature on transgender medicine on PubMed over the last five years was conducted. Existing statistics indicate that unacceptable bias and discrimination are occurring, making trans patients less likely to seek care. There are emerging initiatives that address the transgender and gender non-conforming population. Ongoing needs include defining what constitutes "gender equal," understanding the continuum of gender identity, and establishing and implementing guidelines for gender equal counseling and care. With the routine practice of defining sex at birth and equating sex with gender in the health care setting, the transgender patient encounters multiple barriers to accessing and acquiring health care services. These strict gender labels appear to preclude the institution of gender equal care. Care templates on gender equal patient encounters should be implemented to better address transgender health needs in a non-biased manner. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  17. Discriminating male and female voices: differentiating pitch and gender.

    Latinus, Marianne; Taylor, Margot J

    2012-04-01

    Gender is salient, socially critical information obtained from faces and voices, yet the brain processes underlying gender discrimination have not been well studied. We investigated neural correlates of gender processing of voices in two ERP studies. In the first, ERP differences were seen between female and male voices starting at 87 ms, in both spatial-temporal and peak analyses, particularly the fronto-central N1 and P2. As pitch differences may drive gender differences, the second study used normal, high- and low-pitch voices. The results of these studies suggested that differences in pitch produced early effects (27-63 ms). Gender effects were seen on N1 (120 ms) with implicit pitch processing (study 1), but were not seen with manipulations of pitch (study 2), demonstrating that N1 was modulated by attention. P2 (between 170 and 230 ms) discriminated male from female voices, independent of pitch. Thus, these data show that there are two stages in voice gender processing; a very early pitch or frequency discrimination and a later more accurate determination of gender at the P2 latency.

  1. Age and gender differences in health risk perception.

    Kim, YoungHo; Park, InKyoung; Kang, SooJin

    2018-03-01

    The current study investigated how adolescents perceive their own health risks and compare their own likelihood of health risks with that of others of the same age. Moreover, the study identified the differences in health risk perceptions between males and females. A total of 625 adolescents (314 males and 311 females) from the Nowon district, geographically located in northern Seoul, voluntarily participated. In order to measure health risk perceptions a Korean version of self-other risk judgments profile was used. The findings indicated that study participants, regardless of gender and age, tend to underestimate their vulnerability to majority of health risk events. Furthermore, there were significant gender and age differences in health risk perception and perception bias in all health risk domains. The present study suggests that further research is needed to identify realistic and unrealistic perception mechanism for a large number of people from different demographic and socioeconomic backgrounds.

I argue that  attempts of gerontologists’ to eroticize old age have to contend with the widespread notion that the desire for sex is inevitably lost with age. Thus, in the retiree associations that were studied, men had a tendency to assume they are not ‘old’ because their erectile function was still in good condition, and divorced or widowed women, in senior citizen associations, tend to regard themselves as happy due to having freed themselves from the sexual obligations imposed by marriage. In both cases, the dominant belief that there is a loss of sexual desire in old age was reproduced.

  6. Gender relations and applied research on aging.

    Calasanti, Toni

    2010-12-01

    As a concept in gerontology, gender appears as lists of traits learned through socialization when theorized at all. I argue for a framework that theorizes the intersections of relations of gender inequality with those of age. This framework holds that men and women gain resources and bear responsibilities, in relation to one another, by virtue of mundane categorization into naturalized stratified groups. Current research shows that this approach allows explanation of gender differences, which appear in many reports but which usually go untheorized, as responses to social inequality. I illustrate applications to research and practice in relation to three areas of old age experiences: financial security, spousal care work, and health. Throughout, I discuss implications of focusing on inequality to enhance our abilities to engage in effective research, practice, and policy for older people, women and men alike. For instance, an understanding of the gender division of labor and workplace discrimination makes clear that financial status in later life cannot be reduced to individual choices concerning paid labor or retirement planning. And understanding that people orient their behaviors to gender ideals allows us to see that men and women perform spousal care in similar and different ways that require varied responses from practitioners; it also reveals contexts in which men engage in positive health behaviors. Finally, I argue that gerontologists interested in facilitating favorable outcomes for old people should consider research and practice that would disrupt, not reinforce, the bases of gender inequalities in later life.

The sample was constituted by 163 males and females, between the ages of 20 and 60 years, single and married, and from middle class strata. They were administered the Scale of Satisfaction with Life, developed by Diener, with and added item to measure the degrees of happiness. There is no significan! statistically difference between genders; according to age the only significan contras! was between 30 and 50 years, with the notation that the highest means corresponded to ages 50 and 60 years old; married people were found to be happier than single ones. In general, the majority reported feeling happy, the other degrees contained very few frecuencies.

  8. Examining aging sexual stigma attitudes among adults by gender, age, and generational status.

    Syme, Maggie L; Cohn, Tracy J

    2016-01-01

    Stigma related to later life sexuality could produce detrimental effects for older adults, through individual concerns and limited sexual health care for older adults. Identifying groups at risk for aging sexual stigma will help to focus interventions to reduce it. Accordingly, the purpose of this study was to examine cross-sectional trends in aging sexual stigma attitudes by age group, generational status, and gender. An online survey was administered to a national sample of adults via a crowdsourcing tool, in order to examine aging sexual stigma across age groups, generational status, and gender (N = 962; 47.0% male, 52.5% female, and .5% other; mean age = 45 years). An aging sexual stigma index was formulated from the attitudinal items of the Aging Sexual Knowledge and Attitudes Scale. This sample reported moderately permissive attitudes toward aging sexuality, indicating a low level of aging sexual stigma. Though descriptive data showed trends of stigma attitudes increasing with age and later generations, there were no significant differences between age groups or generations in terms of aging sexual stigma beliefs. Men, regardless of age and/or generation, were found to espouse significantly higher stigmatic beliefs than women or those reporting 'other' gender. Aging sexual stigma beliefs may not be prevalent among the general population as cohorts become more sexually liberal over time, though men appear more susceptible to these beliefs. However, in order to more comprehensively assess aging sexual stigma, future research may benefit from measuring explicit and implicit aging sexual stigma beliefs.

  9. The diagnosis of Androgenic Deficiency of the Aging Male and the paths of male sexual desire

    2015-06-01

    Full Text Available This article discusses the diagnosis of Androgenic Deficiency of the Aging Male (ADAM and the controversies and disputes over it, based on the re-medicalization of sexuality. The analysis is based on interviews with urologists and endocrinologists, and the different approaches of these two medical specialties elucidate divergent conceptions of body and sexuality present in the biomedical knowledge, and the struggle for hegemony in the scientific field. By comparing the meanings attributed to ADAM and to another male sexual dysfunction, the Erectile Dysfunction (ED, we intend to reflect about the difficulties inherent in the biological reduction of sexuality and the reiteration of gender norms in the medical discourse concerning the male body and sexuality.

    Full Text Available Abstract Background This study aims to analyze sex differences in mice aging kidney. We applied a proteomic technique based on subfractionation, and liquid chromatography coupled with 2-DE. Samples from male and female CD1-Swiss outbred mice from 28 weeks, 52 weeks, and 76 weeks were analysed by 2-DE, and selected proteins were identified by matrix assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS. Results This proteomic analysis detected age-related changes in protein expression in 55 protein-spots, corresponding to 22 spots in males and 33 spots in females. We found a protein expression signature (PES of aging composed by 8 spots, common for both genders. The identified proteins indicated increases in oxidative and proteolytic proteins and decreases in glycolytic proteins, and antioxidant enzymes. Conclusion Our results provide insights into the gender differences associated to the decline of kidney function in aging. Thus, we show that proteomics can provide valuable information on age-related changes in expression levels of proteins and related modifications. This pilot study is still far from providing candidates for aging-biomarkers. However, we suggest that the analysis of these proteins could suggest mechanisms of cellular aging in kidney, and improve the kidney selection for transplantation.

  12. Should male gender assignment be considered in the markedly virilized patient With 46,XX and congenital adrenal hyperplasia?

    Lee, Peter A; Houk, Christopher P; Husmann, Douglas A

    2010-10-01

    We assess the outcome in 46,XX men with congenital adrenal hyperplasia who were born with Prader 4 or 5 genitalia and assigned male gender at birth. After receiving institutional review board approval and subject consent we reviewed the medical records of 12 men 35 to 69 years old with 46,XX congenital adrenal hyperplasia, of whom 6 completed social and gender issue questionnaires. All subjects were assigned male gender at birth, were diagnosed with virilizing congenital adrenal hyperplasia at age greater than 3 years and indicated a male gender identity with sexual orientation to females. Ten of the 12 subjects had always lived as male and 2 who were reassigned to female gender in childhood subsequently self-reassigned as male. Nine of the 12 men had long-term female partners, including 7 married 12 years or more. The 3 subjects without a long-term female partner included 1 priest, 1 who was reassigned female gender, married, divorced and self-reassigned as male, and 1 with a girlfriend and sexual activity. All except the priest and the subject who was previously married when female indicated a strong libido and frequent orgasmic sexual activity. Responses to self-esteem, masculinity, body image, social adjustment and symptom questionnaires suggested adjustments related to the extent of familial and social support. Outcome data on severely masculinized 46,XX patients with congenital adrenal hyperplasia who were assigned male gender at birth indicate male gender identity in adulthood with satisfactory male sexual function in those retaining male genitalia. In men who completed questionnaires results were poorer in those lacking familial/social support. Male gender of rearing may be a viable option for parents whose children are born with congenital adrenal hyperplasia, a 46,XX karyotype and male genitalia, although positive parental and other support, and counseling are needed for adjustment.

    Background Systemic Arterial Hypertension (SAH) is one of the main risk factors for Coronary Artery Disease (CAD), in addition to male gender. Differences in coronary artery lesions between hypertensive and normotensive individuals of both genders at the Coronary Computed Tomography Angiography (CCTA) have not been clearly determined. Objective To Investigate the calcium score (CS), CAD extent and characteristics of coronary plaques at CCTA in men and women with and without SAH. Methods Prospective cross-sectional study of 509 patients undergoing CCTA for CAD diagnosis and risk stratification, from November 2011 to December 2012, at Instituto de Cardiologia Dante Pazzanese. Individuals were stratified according to gender and subdivided according to the presence (HT +) or absence (HT-) of SAH. Results HT+ women were older (62.3 ± 10.2 vs 57.8 ± 12.8, p = 0.01). As for the assessment of CAD extent, the HT+ individuals of both genders had significant CAD, although multivessel disease is more frequent in HT + men. The regression analysis for significant CAD showed that age and male gender were the determinant factors of multivessel disease and CS ≥ 100. Plaque type analysis showed that SAH was a predictive risk factor for partially calcified plaques (OR = 3.9). Conclusion Hypertensive men had multivessel disease more often than women. Male gender was a determinant factor of significant CAD, multivessel disease, CS ≥ 100 and calcified and partially calcified plaques, whereas SAH was predictive of partially calcified plaques.

    To examine possible reasons why a male fetus constitutes a risk factor for preterm delivery. Retrospective study of deliveries from hospital database in a UK teaching hospital. The population comprised all deliveries >23 weeks over an 11-year period, excluding multiples, terminations and pregnancies with major abnormalities including indeterminate gender. Obstetric variables and outcomes were initially compared in male and female babies for preterm births in different gestation bands, extreme (pathways that might explain the male excess were tested. 75,725 deliveries occurred, of which 4003 (5.3%) were preterm. Males delivered preterm more frequently (OR 1.13, 95% CI 1.06-1.20). This was due to spontaneous (OR 1.30, 95% CI 1.19-1.42) but not iatrogenic (OR 0.96, 95% CI 0.87-1.05) preterm birth. There was an increased risk of pre eclampsia among preterm females. Although males were larger, and male pregnancies were more frequently nulliparous and affected by some other obstetric complications (abruption, urinary tract infection), these did not account for their increased risk. Any effect of growth restriction could not be properly determined. Being male carries an increased risk of spontaneous but not iatrogenic preterm birth. The reasons behind this remain obscure.

    We focus on Japanese individuals with gender identity disorder (GID), especially male-to-female (MTF) GID, who have experienced difficulty in adapting to social life. We clarify what gender dysphoria is, and we examine methods of intervention. Semi-structured interviews were conducted with 11 individuals with MTF-GID from August 2015 to April 2017. We categorized the subjects'experiences regarding dysphoria into the 'Onset of gender dysphoria,' 'Experience of feeling gender dysphoria,' and 'Changes due to receiving medical care.' The subjects reported experiencing great pain and distress because they did not fully understand that they were experiencing dysphoria and could not align their gender identity and their self-identity. All subjects described their experiences of dysphoria as negative. Additionally, all said that the dysphoria was alleviated by a medical intervention such as visiting a gender clinic, receiving a diagnosis and treatment, and changing their physical sex to the sex congruent with their gender identity. The provision of information at the gender clinic and the physical changes achieved by medical intervention exerted a positive effect both mentally and socially on the subjects, who suffered various physical, mental and social problems.

    Migraine headache is one of the most common primary headache disorders and is three times more prevalent in women than in men, especially during the reproductive ages. The neurobiological basis of the female dominance has been partly established. The present study aimed to investigate the effect of gender on the headache manifestations in migraine patients. The study group consisted of 2082 adult patients from five different hospitals' tertiary care-based headache clinics. The relationship between headache characteristics and gender was evaluated in migraine with aura (MwA) and migraine without aura (MwoA). The duration, severity, frequency of headache and associated symptoms were evaluated in both genders and age-dependent variations and analyzed in two subgroups. Women with migraine were prone to significantly longer duration and intensity of headache attacks. Nausea, phonophobia and photophobia were more prevalent in women. Median headache duration was also longer in women than in men in MwA (p = 0.013) and MwoA (p < 0.001). Median headache intensity was higher in women than in men in MwA (p = 0.010) and MwoA (p = 0.009). The frequency of nausea was significantly higher in women than in men in MwA (p = 0.049). Throbbing headache quality and associated features (nausea, photophobia, and phonophobia) were significantly more frequent in women than in men in MwoA. The gender impact varied across age groups and significant changes were seen in female migraineurs after age 30. No age-dependent variation was observed in male migraineurs. Gender has an influence on the characteristics of the headache as well as on the associated symptoms in migraine patients, and this impact varies across the age groups, particularly in women. © International Headache Society 2014.

  17. Gender and age in media education

    Elżbieta Gajek,

    2009-12-01

    Full Text Available Nowadays mass media shape the perception of social values and roles. Thus, aspects of media education that deal with various kinds of inequalities influence general sensitivity to diversity and its consequences. In this respect media and intercultural competences interrelate. Not only minorities’ rights have to be secured, but also majorities rights have to considered if it happens that majorities are discriminated. Widely accepted gender and age inequalities presented on the media in stereotypes and safely-looking conservatist behaviours may lead to harassment and even violence. That is why understanding media messages and identifying overt and covert forms of discrimination are of special interest of educators. In this article several activities for class teachers are presented to encourage them to introduce the touchy topic of gender and age inequalities into their school practice.

  18. [Influence of aging on male sexual health].

    Seisen, T; Rouprêt, M; Costa, P; Giuliano, F

    2012-06-01

    With the increase in life expectancy, men's sexual health has become a major concern for elderly couples. Erectile dysfunction (ED) is responsible for a 50 % decrease of sexually active men between 60 and 85. The aim of this study was to identify objective elements to evaluate the influence of age on male sexual health. Data on the effects of aging on men's sexual health have been explored in Medline and Embase using the MeSH keywords: prostate; sexuality and erectile dysfunction; aging. The articles were selected based on their methodology, relevance, date and language of publication. ED concerns 64 % of 70 years old patients and up to 77.5 % after 75 years. The screening of this pathology is based on standardized diagnostic tools. The most used of them remains the "International Index of Erectile function" which, in its simplified version with 5 items (IIEF-5 or SHIM), presents at the cutoff score of 21, a sensitivity of 98 %, a specificity of 88 % and a kappa index of 0.82. The ED is often responsible for a decrease in the quality of life for 60 % of elderly couples wishing to pursue sexual activity. Some diagnostic tools, such as the "Self-Esteem And Relationship" (SEAR) questionnaire or the "Sexual Experience Questionnaire" (SEX-Q) assess individual and couple satisfaction. Physiological aging seems to favor erection disorders by the development of an Androgen Deficiency of the Aging Male (ADAM) but pathological aging appears to be primarily responsible. Cardiovascular or neurological diseases and lower urinary tract symptoms (LUTS) are, with the polymedication, modifiable risk factors of ED to systematically screen in elderly subjects. Many diagnostic tools allow to detect ED and assess the impact on the quality of life of elderly men. The fundamental element of the management of ED is the research of modifiable risk factors including cardiovascular. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    Later parenting is considered by many to have advantages, parents-to-be may feel themselves more stable to rear children. In addition, many men start a second family later in life. Thus, paternal age becomes an emerging issue. Aging affects male fertility by a scope of factors, which are not fully understood to date. Generally, the amount of produced sperm cells as well as their motility decreases with age, as testicular histological architecture deteriorates. Decreased fecundity and an increased risk for disturbed pregnancies occur with advancing paternal age. Some rare autosomal dominant pathologies are clearly related to paternal age. Altered patterns of epigenetics/gene expression in aging sperm seem to affect a range of neurocognitive disorders and also metabolic dyshomeostasis across generations. Such effects refer to men older than 40 years and may have impact on socio-economic issues. Nevertheless, councelling of older men seeking paternity should be patient-oriented and weigh statistical probabilities against the right for individual life-planning. Copyright © 2013 Elsevier Ltd.

  1. Sexual function of the ageing male.

    Corona, Giovanni; Rastrelli, Giulia; Maseroli, Elisa; Forti, Gianni; Maggi, Mario

    2013-08-01

    With the progressive increase in the proportion of older people, there is an increasing interest in characterizing the modifications of sexual health and the effect of its perturbations as a function of the aging process. The aim of this review is to summarize the available evidence regarding the age-dependent modifications of male sexual function and their interaction with general health and age-dependent modification of endocrine function. Elderly patients are often affected by multiple organic diseases which can interfere with sexual function. Despite this evidence, several studies have indicated that, with advancing age, normal erections are not an absolute prerequisite to remain sexually active. Good physical health, the availability of a partner, and a regular and stable pattern of sexual activity earlier in life predict the maintenance of sexual activity in old age. Conversely, there are no convincing data that hormonal changes, associated with aging, have a primary role in underlying changes in sexual function in healthy aging men. Nonetheless, sexual dysfunctions especially in elderly people are poor investigated. Asking about sexual health remains difficult or embarrassing for many primary care physicians. In addition, many patients find it difficult to raise sexual issues with their doctor. This situation often results in sexual issues not being adequately addressed thus resulting in depression, social withdrawal and delayed diagnosis of underlying medical conditions often resulting in forthcoming cardiovascular events. Education and permission from a health care professional may help to alter such misconceptions. Information from physicians regarding normal age-related changes in sexuality and encouragement, together with advice on how to continue meaningful sexual relations, may play a key role in altering such negative attitudes.

  2. Gender bias in the evaluation of new age music.

    Colley, Ann; North, Adrian; Hargreaves, David J

    2003-04-01

    Eminent composers in Western European art music continue to be predominantly male and eminence in contemporary pop music is similarly male dominated. One contributing factor may be the continuing under-valuation of women's music. Possible anti-female bias in a contemporary genre was investigated using the Goldberg paradigm to elicit judgments of New Age compositions. Since stronger stereotyping effects occur when information provided about individuals is sparse, fictitious male and female composers were presented either by name only or by name with a brief biography. Evidence for anti-female bias was found in the name-only condition and was stronger when liking for the music was controlled. Other findings were the tendency for females to give higher ratings, and the association of gender differences in liking of the music with ratings of quality in the name-only condition. These results are relevant to the design of formal assessment procedures for musical composition.

  3. Aging and sex hormones in males

    Decaroli, Maria Chiara

    2017-01-01

    ABSTRACT Several large cohort studies have disclosed the trajectories of sex steroids changes overtime in men and their clinical significance. In men the slow, physiological decline of serum testosterone (T) with advancing age overlaps with the clinical condition of overt, pathological hypogonadism. In addition, the increasing number of comorbidities, together with the high prevalence of chronic diseases, all further contribute to the decrease of serum T concentrations in the aging male. For all these reasons both the diagnosis of late-onset hypogonadism (LOH) in men and the decision about starting or not T replacement treatment remain challenging. At present, the biochemical finding of T deficiency alone is not sufficient for diagnosing hypogonadism in older men. Coupling hypogonadal symptoms with documented low serum T represents the best strategy to refine the diagnosis of hypogonadism in older men and to avoid unnecessary treatments. PMID:27831823

  5. Gender, Age, Social differences and Climate Change

    Petrucci, Alessandra; Salvini, Silvana

    2017-04-01

    Climate and society evolve together in a manner that could place already vulnerable areas and their population at a greater risk to extreme weather events. While efforts have been devoted to better planning preparedness and responses to weather extremes, the interactions among various stakeholders who deal with hazard mitigation and response, and the community members, also related with gender and age differences, are not completely understood. In contrast to physical vulnerability, which arises from the potential for environmental extremes to create adverse physiological changes, social vulnerability arises from the potential for these extreme events to cause changes in people's behavior. People can vary in their potential for injury to themselves and their families. They also vary in the potential for destruction of their homes and workplaces, as well as the destruction of the transportation systems and locations for shopping and recreation they use in their daily activities. It is important to recognize that social vulnerability is not randomly distributed either demographically or geographically. In particular, the social vulnerability arising from a lack of psychological resilience, social network integration, economic assets, and political power vary across demographic groups. Some of these components of social vulnerability can be predicted by demographic characteristics such as gender, age, education, income, and ethnicity. This review explores the gender and social difference dimensions of vulnerability and adaptive capacity in relation to climate change.

  6. Gender difference of alanine aminotransferase elevation may be associated with higher hemoglobin levels among male adolescents.

    Solomon Chih-Cheng Chen

    Full Text Available BACKGROUND: To explore the gender difference of ALT elevation and its association with high hemoglobin levels. METHODS: A cross-sectional study of 3547 adolescents (2005 females, mean age of 16.5?.3 years who were negative for hepatitis B surface antigen received health checkups in 2006. Body mass index (BMI, levels of hemoglobin, ALT and cholesterol were measured. ALT >42 U/L was defined as elevated ALT. Elevated ALT levels were detected in 112 of the 3547 participants (3.3%, more prevalent in males than in females (5.4% vs. 1.4%, p11 g/dl in females or >13.5 g/dl in males, but the cumulative cases of elevated ALT increased more quickly in males. Proportion of elevated ALT increased as either the BMI or hemoglobin level rise, more apparent in male adolescents. Logistic regression modeling showed odds ratio (95% confidence interval were 24.7 (15.0-40.6 for BMI ≥27 kg/m(2; 5.5 (2.9-10.4 for BMI 24-27 kg/m(2; 2.7 (1.3-5.5 for Q5 (top 20th percentile hemoglobin level; and 2.6 (1.6-4.1 for male gender. Further separately fitting the logistic models for two genders, the significance of Q5 hemoglobin level only appeared in the males. CONCLUSIONS: High hemoglobin level is a significant risk factor of ALT elevation after control hepatitis B, obesity and gender. Males have greater risk of abnormal liver function which may be associated with higher hemoglobin levels.

  7. Age and Gender Effects in Recent Violence Perpetration.

    Although we know much about the effects of violence on victims, we know less about individuals who perpetrate violence. In the present study, we used a large, nationally representative sample of adults (National Comorbidity Study-Replication; n = 9,282) to examine demographics (i.e., age and gender) and social, occupational, and cognitive functioning among perpetrators of recent violence. We found that recent violence was more prevalent among younger individuals and males (i.e., these groups were more likely to engage in at least one act of violence). Among those who did engage in violence, there was no effect of age or gender on violence frequency (i.e., number of violent acts engaged in over the past year). Furthermore, gender moderated the effect of age on recent violence prevalence, but not violence frequency. Finally, those reporting violence over the past year showed greater impairment in all examined domains of functioning, but there was no association between impairment and frequency of violence. This study represents one of the first attempts to utilize 12-month prevalence data to explore the lifetime trajectory of violence among those who perpetrate it, which seems to peak in young adulthood and then decrease across the life span. Furthermore, although males are more likely to engage in violence than females, adults who engage in at least one act of violence demonstrate no difference in frequency of yearly violent acts, regardless of gender. Finally, it is apparent that merely engaging in any acts of violence over the past year is associated with functioning problems. Overall, most significant differences emerged between those who do and do not engage in violence, which is key for informing violence risk assessment and prevention.

  8. Child Sexual Behaviors in School Context: Age and Gender Differences.

    Miragoli, Sarah; Camisasca, Elena; Di Blasio, Paola

    2017-01-01

    The main purpose of the study was to explore the child sexual behaviors that Italian teachers have observed in the school context. A representative sample of 227 children, from 5 to 10 years old, was rated by their teachers through the Child Sexual Behavior Inventory. Frequencies of sexual behaviors among children aged 5 to 6, 7 to 8, and 9 to 10 are presented. Younger children showed a broader range of sexual behaviors that decrease with the growing age, such as males in comparison to females. Moreover, findings showed that child sexual behavior is not only related to age and gender but also to family characteristics. These results suggested that child sexual behaviors reported by teachers through the Child Sexual Behavior Inventory may provide useful information about the development of children's sexuality. The knowledge of age appropriate sexual behaviors can help teachers discern normal sexual behaviors from problematic sexual behaviors.

    Full Text Available Objectives: Auditory Brain Stem Response (ABR is a result of eight nerve and brain stem nuclei stimulation. Several factors may affect the latencies, interpeak latencies and amplitudes in ABR especially sex and age. In this study, age and sex influence on ABR were studied. Methods: This study was performed on 120 cases (60 males and 60 females at Akhavan rehabilitation center of university of welfare and rehabilitation sciences, Tehran, Iran. Cases were divided in three age groups: 18-30, 31-50 and 51-70 years old. Each age group consists of 20 males and 20 females. Age and sex influences on absolute latency of wave I and V, and IPL of I-V were examined. Results: Independent t test showed that females have significantly shorter latency of wave I, V, and IPL I-V latency (P<0.001 than males. Two way ANOVA showed that latency of wave I, V and IPL I-V in 51-70 years old group was significantly higher than 18-30 and 31-50 years old groups (P<0.001 Discussion: According to the results of present study and similar studies, in clinical practice, different norms for older adults and both genders should be established.

  10. Influence of age and gender before and after liver transplantation.

    Burra, Patrizia; De Martin, Eleonora; Gitto, Stefano; Villa, Erica

    2013-02-01

    Women constitute a particular group among patients with chronic liver disease and in the post-liver transplantation (LT) setting: they are set apart not only by traditional differences with respect to men (ie, body mass index, different etiologies of liver disease, and accessibility to transplantation) but also in increasingly evident ways related to hormonal changes that characterize first the fertile age and subsequently the postmenopausal period (eg, disease course variability and responses to therapy). The aim of this review is, therefore, to evaluate the role of the interplay of factors such as age, gender, and hormones in influencing the natural history of chronic liver disease before and after LT and their importance in determining outcomes after LT. As the population requiring LT ages and the mean age at transplantation increases, older females are being considered for transplantation. Older patients are at greater risk for nonalcoholic steatohepatitis, osteoporosis, and a worse response to antiviral therapy. Female gender per se is associated with a greater risk for osteoporosis because of metabolic changes after menopause, the bodily structure of females, and, in the population of patients with chronic liver disease, the greater prevalence of cholestatic and autoimmune liver diseases. With menopause, the fall of protective estrogen levels can lead to increased fibrosis progression, and this represents a negative turning point for women with chronic liver disease and especially for patients with hepatitis C. Therefore, the notion of gender as a binary female/male factor is now giving way to the awareness of more complex disease processes within the female gender that follow hormonal, social, and age patterns and need to be addressed directly and specifically.

  12. Speeding driving behaviour: Age and gender experimental analysis

    Teo Sir Hiang

    2016-01-01

    Full Text Available Road safety is a substantial issue worldwide. Speeding contributed to one-third of all the fatal crashes reported from year 2002 to 2011 with young drivers reported to have the highest fatality and injury rates. This paper studied on the speeding driving behavior of 10 teenagers and 10 adults, from both genders. The aim was to investigate the relationship between age and gender with speeding driving behavior. The drivers were required to drive within an enclosed compound by using a test car. Results showed young and male drivers averagely travelled at higher velocity before entering the roundabout and at the same time accelerate to higher velocity upon exiting the roundabout compared to old and female drivers.

  13. Age-dependent male mating investment in Drosophila pseudoobscura.

    Sumit Dhole

    Full Text Available Male mating investment can strongly influence fitness gained from a mating. Yet, male mating investment often changes with age. Life history theory predicts that mating investment should increase with age, and males should become less discriminatory about their mate as they age. Understanding age-dependent changes in male behavior and their effects on fitness is important for understanding how selection acts in age-structured populations. Although the independent effects of male or female age have been studied in many species, how these interact to influence male mating investment and fitness is less well understood. We mated Drosophila pseudoobscura males of five different age classes (4-, 8-, 11-, 15-, 19-day old to either young (4-day or old (11-day females, and measured copulation duration and early post-mating fecundity. Along with their independent effects, we found a strong interaction between the effects of male and female ages on male mating investment and fitness from individual matings. Male mating investment increased with male age, but this increase was more prominent in matings with young females. Male D. pseudoobscura made smaller investments when mating with old females. The level of such discrimination based on female age, however, also changed with male age. Intermediate aged males were most discriminatory, while the youngest and the oldest males did not discriminate between females of different ages. We also found that larger male mating investments resulted in higher fitness payoffs. Our results show that male and female ages interact to form a complex pattern of age-specific male mating investment and fitness.

    Age and gender are two important physiological variables which might influence the personality of an individual. The influence of age and gender on big five personality domains in Indian population was assessed in this cross-sectional study that included 155 subjects (female = 76, male = 79) aged from 16-75 years. Big five personality factors were evaluated using 60-item NEO-Five Factor Inventory (NEO-FFI) at a single point in time. Among the big five factors of personality, Conscientiousness was positively correlated (r = 0.195; P personality traits might change with age, and is gender-dependent.

    2008-01-01

    The study of gender in feminism should not only concentrate on female gender roles and queer transgressions of established gender roles, but should also include an in-depth discussion on male gender roles as they exist in society. This paper focuses on the metrosexual and the retrosexual trends which have recently affected the male gender role in society. The emergence of the metrosexual in the 1990s through 2005 was a profound change in the traditional male gender role which allowed men to ...

  16. Male gender is not a risk factor for the outcome of laparoscopiccholecystectomy: A single surgeon experience

    Al-Mulhim, Abdulmohsen A.

    2008-01-01

    Previous studies regarding the outcome of laparoscopic cholecystectomy(LC) in men have reported inconsistent findings. We conducted thisprospective study to test the hypothesis that the outcome of LC is worse inmen than women. Between 1997 and 2002, a total of 391 consecutive LCs wereperformed by a single surgeon at King Fahd Hospital of the University. Wecollected and analyzed data including age, gender, body mass index (kg/m2),the American Society of Anesthesiologists (ASA) class, mode of admission(elective or emergency), indication for LC (chronic or acute) cholecystitis[AC]), comorbid disease, previous abdominal surgery, conversion to opencholecystectomy, complications, operation time and length of postoperativehospital stay. Bivariate analysis showed that both genders were matched forage, ASA class and mode of admission. The incidence of AC (P=0.003) andcomobrid disease (P=0.031) were significantly higher in men. Women weresignificantly more obese than men (P<0.001) and had a higher incidence ofprevious abdominal surgery (P=0.017). There were no statistical differencesbetween genders with regards to rate of conversion (P=0.372) andcomplications (P=0.647) and operation time (P=0.063). The postoperative staywas significantly longer in men than women (P=0.001). Logistic regressionanalysis showed that male gender was not an independent predictor ofconversion (Odds ratio [or] = 0.37 and P=0.43) or complications (OR=0.42,P=0.42). Linear regression analysis showed that male gender was not anindependent predictor of the operation time, but was associated with a longerpostoperative stay (P=0.02). Male gender is not an independent risk factorfor satisfactory outcome of LC in the experience of a single surgeon. (author)

  17. Separation anxiety among birth-assigned male children in a specialty gender identity service.

    VanderLaan, Doug P; Santarossa, Alanna; Nabbijohn, A Natisha; Wood, Hayley; Owen-Anderson, Allison; Zucker, Kenneth J

    2018-01-01

    Previous research suggested that separation anxiety disorder (SAD) is overrepresented among birth-assigned male children clinic-referred for gender dysphoria (GD). The present study examined maternally reported separation anxiety of birth-assigned male children assessed in a specialty gender identity service (N = 360). SAD was determined in relation to DSM-III and DSM-IV criteria, respectively. A dimensional metric of separation anxiety was examined in relation to several additional factors: age, ethnicity, parental marital status and social class, IQ, gender nonconformity, behavioral and emotional problems, and poor peer relations. When defined in a liberal fashion, 55.8% were classified as having SAD. When using a more conservative criterion, 5.3% were classified as having SAD, which was significantly greater than the estimated general population prevalence for boys, but not for girls. Dimensionally, separation anxiety was associated with having parents who were not married or cohabitating as well as with elevations in gender nonconformity; however, the association with gender nonconformity was no longer significant when statistically controlling for internalizing problems. Thus, SAD appears to be common among birth-assigned males clinic-referred for GD when defined in a liberal fashion, and more common than in boys, but not girls, from the general population even when more stringent criteria were applied. Also, the degree of separation anxiety appears to be linked to generic risk factors (i.e., parental marital status, internalizing problems). As such, although separation anxiety is common among birth-assigned male children clinic-referred for GD, it seems unlikely to hold unique significance for this population based on the current data.

  18. Male-to-female gender dysphoria: Gender-specific differences in resting-state networks.

    Recent research found gender-related differences in resting-state functional connectivity (rs-FC) measured by functional magnetic resonance imaging (fMRI). To the best of our knowledge, there are no studies examining the differences in rs-FC between men, women, and individuals who report a discrepancy between their anatomical sex and their gender identity, i.e. gender dysphoria (GD). To address this important issue, we present the first fMRI study systematically investigating the differences in typical resting-state networks (RSNs) and hormonal treatment effects in 26 male-to-female GD individuals (MtFs) compared with 19 men and 20 women. Differences between male and female control groups were found only in the auditory RSN, whereas differences between both control groups and MtFs were found in the auditory and fronto-parietal RSNs, including both primary sensory areas (e.g. calcarine gyrus) and higher order cognitive areas such as the middle and posterior cingulate and dorsomedial prefrontal cortex. Overall, differences in MtFs compared with men and women were more pronounced before cross-sex hormonal treatment. Interestingly, rs-FC between MtFs and women did not differ significantly after treatment. When comparing hormonally untreated and treated MtFs, we found differences in connectivity of the calcarine gyrus and thalamus in the context of the auditory network, as well as the inferior frontal gyrus in context of the fronto-parietal network. Our results provide first evidence that MtFs exhibit patterns of rs-FC which are different from both their assigned and their aspired gender, indicating an intermediate position between the two sexes. We suggest that the present study constitutes a starting point for future research designed to clarify whether the brains of individuals with GD are more similar to their assigned or their aspired gender.

  19. Negative Gender Ideologies and Gender-Science Stereotypes Are More Pervasive in Male-Dominated Academic Disciplines

    Sarah Banchefsky

    2018-02-01

    Full Text Available Male-dominated work environments often possess masculine cultures that are unwelcoming to women. The present work investigated whether male-dominated academic environments were characterized by gender ideologies with negative implications for women. A survey of 2622 undergraduates across a variety of academic majors examined how gender imbalance within the major corresponded with students’ gender ideologies. We hypothesized that men in male-dominated domains might justify their dominance and prototypical status by adopting gender ideologies and stereotypes that denigrate women and treat men as the normative and superior group. Confirming this hypothesis, men in increasingly male-dominated academic majors were more likely to endorse Assimilationism—that women should adapt and conform to masculine work norms in order to succeed—and Segregationism—that men and women should pursue traditional social roles and careers. Moreover, they were less likely to endorse Gender Blindness—that attention to gender should be minimized. They were also more likely to agree with the gender-science stereotype that men do better in math and science than women. In contrast, gender imbalance in the major did not influence women’s gender ideologies, and women in increasingly male-dominated majors were significantly less likely to endorse the gender-science stereotype.

  1. Cervical lordosis: the effect of age and gender.

    Been, Ella; Shefi, Sara; Soudack, Michalle

    2017-06-01

    Cervical lordosis is of great importance to posture and function. Neck pain and disability is often associated with cervical lordosis malalignment. Surgical procedures involving cervical lordosis stabilization or restoration must take into account age and gender differences in cervical lordosis architecture to avoid further complications. Therefore, the purpose of the present study was to evaluate differences in cervical lordosis between males and females from childhood to adulthood. This is a retrospective descriptive study. A total of 197 lateral cervical radiographs of patients aged 6-50 years were examined. These were divided into two age groups: the younger group (76 children aged 6-19; 48 boys and 28 girls) and the adult group (121 adults aged 20-50; 61 males and 60 females). The retrospective review of the radiographs was approved by the institutional review board. On each radiograph, six lordosis angles were measured including total cervical lordosis (FM-C7), upper (FM-C3; C1-C3) and lower (C3-C7) cervical lordosis, C1-C7 lordosis, and the angle between foramen magnum and the atlas (FM-C1). Wedging angles of each vertebral body (C3-C7) and intervertebral discs (C2-C3 to C6-C7) were also measured. Vertebral body wedging and intervertebral disc wedging were defined as the sum of the individual body or disc wedging of C3 to C7, respectively. Each cervical radiograph was classified according to four postural categories: A-lordotic, B-straight, C-double curve, and D-kyphotic. The total cervical lordosis of males and females was similar. Males had smaller upper cervical lordosis (FM-C3) and higher lower cervical lordosis (C3-C7) than females. The sum of vertebral body wedging of males and females is kyphotic (anterior height smaller than posterior height). Males had more lordotic intervertebral discs than females. Half of the adults (51%) had lordotic cervical spine, 41% had straight spine, and less than 10% had double curve or kyphotic spine. Children had

  2. The effect of age on encounters between male crab spiders

    Helen H. Hu; Douglass H. Morse

    2004-01-01

    In males that compete aggressively for females, size and age may determine which males obtain access to these females. In the present study, we use the crab spider, Misumena vatia, a species with males that do not grow after becoming sexually mature adults, to test the hypothesis that age affects the success of males competing for access to females. M. vatia is an excellent species to test this hypothesis because it is possible to disentangle age from size, characters that typically vary toge...

  3. Aggression Toward Gay Men as Gender Role Enforcement: Effects of Male Role Norms, Sexual Prejudice, and Masculine Gender Role Stress

    Parrott, Dominic J.

    2009-01-01

    This study examined sexual prejudice and masculine gender role stress as mediators of the relations between male gender norms and anger and aggression toward gay men. Participants were 150 self-identified heterosexual men who completed measures of adherence to male gender role norms, sexual prejudice, masculine gender role stress, and state anger. Participants then viewed a video depicting intimate relationship behavior between two gay men, reported state anger a second time, and competed in a laboratory aggression task against either a heterosexual or a gay male. Results indicated that adherence to the antifemininity norm exerted an indirect effect, primarily through sexual prejudice, on increases in anger. Adherence to the status and antifemininity norms exerted indirect effects, also through sexual prejudice, on physical aggression toward the gay, but not the heterosexual, male. Findings provide the first multivariate evidence for determinants of aggression toward gay men motivated by gender role enforcement. PMID:19558440

  4. Developmental stability in gender-typed preferences between infancy and preschool age.

    Lauer, Jillian E; Ilksoy, Sibel D; Lourenco, Stella F

    2018-04-01

    Infants exhibit visual preferences for gender-typed objects (e.g., dolls, toy vehicles) that parallel the gender-typed play preferences of preschool-aged children, but the developmental stability of individual differences in early emerging gender-typed preferences has not yet been characterized. In the present study, we examined the longitudinal association between infants' (N = 51) performance on an object-preference task, administered between 6 and 13 months of age, and their play preferences at 4 years of age. Greater visual interest in a toy truck relative to a doll in infancy predicted significantly greater male-typical toy and activity preferences (e.g., play with vehicles, videogames) at age 4. These findings suggest that gender-typed object preferences present during the 1st year of life may represent the developmental precursors of gender-typed play preferences observed later in childhood.

    Wiese, Holger; Kloth, Nadine; Gullmar, Daniel; Reichenbach, Jurgen R.; Schweinberger, Stefan R.

    2012-01-01

    Efficient processing of unfamiliar faces typically involves their categorization (e.g., into old vs. young or male vs. female). However, age and gender categorization may pose different perceptual demands. In the present study, we employed functional magnetic resonance imaging (fMRI) to compare the activity evoked during age vs. gender…

  11. Quantitative scintigraphy of sacroiliac joints: effects of age, gender, and laterality

    Vyas, K.; Eklem, M.; Seto, H.; Bobba, V.R.; Brown, P.; Haines, J.; Krishnamurthy, G.T.

    1981-01-01

    The effects of age, gender, and laterality on sacroiliac/sacral ratios obtained during quantitative joint imaging were assessed in 97 nonarthritic control subjects. For the entire group, the right sacroiliac-to-sacral mean ratio of 1.27 in 54 males was significantly higher than the right mean ratio of 1.18 in 53 females. In both genders the right joint ratio tended to be higher than the left in all age groups. The difference in mean ratio between the two joints was wider for males than for females. The age did not afect the joint ratio in either gender. It is concluded that the range of normal sacroiliac-to-sacral ratios are different for males and females and should be taken into account during a quantitative sacroiliac joint imaging examination

  12. Degrees of Intersectionality: Male Rap Artists in Sweden Negotiating Class, Race and Gender

    Kalle Berggren

    2013-06-01

    Full Text Available “Intersectionality” has become a highly influential concept in gender research over the last 25 years. Debates have focused on differences and power asymmetries between women, in terms of race but also addressing class, age, sexuality, ability and nation. However, intersectional paradigms have been used to a much lesser extent in gender studies on men. This article seeks to contribute to an emerging discussion about intersectionality and masculinity by analyzing rap lyrics in Swe-dish songs. The data consists of a broad sample of rap lyrics by male artists 1991-2011, which is analyzed through poststructuralist discourse analysis and queer phenomenology. The analysis shows how classed discourses can be described in terms of orientation and flow, how racialization is articulated in terms of place, and the role of normative notions of gender and sexuality in anti-racist discourses. It is argued that this interconnectedness – class being related to race, which in turn is profoundly gendered – is neither well captured by the prevailing notion of “masculinities” in gender studies on men, nor by the “constitution” vs. “addition” dichotomy in intersectionality debates. Instead, it is suggested that degrees of in-tersectionality might be a more fruitful way of theorizing intersectionality in rela-tion to men.

  13. Dyadic effects of gender minority stressors in substance use behaviors among transgender women and their non-transgender male partners

    Reisner, Sari L.; Gamarel, Kristi E.; Nemoto, Tooru; Operario, Don

    2014-01-01

    Background Despite evidence that interpersonal processes shape health behaviors, research concerning the dyadic effects of gender minority stressors on substance use behaviors of transgender people is scarce. The objective of this study was to use dyadic analysis to examine whether transgender discrimination was associated with substance use among transgender women and their male partners. Methods Transgender women and their male partners (N=191 couples; N=382 individuals) completed questionnaires. Participants’ mean age was 37.1; 79.1% were racial/ethnic minority; 61.3% earned transgender-related discrimination and past 30-day non-marijuana illicit drug use adjusting for age, relationship length, financial hardship, and depressive distress among partners in these dyads. Results Illicit drug use was reported by 31.4% of transgender women and 25.1% of their male partners. Perceived transgender discrimination was independently associated with increased odds of illicit drug use for transgender women (actor effect) but not for their male partners. Financial hardship statistically predicted drug use for both partners (actor effects). There were no partner effects for financial hardship on drug use. Overall, 34.5% of dyads had discrepant substance use. Discrimination scores of male partners differentiated dyads who reported discrepant substance use. Discussion Gender minority stressors are critical to understanding substance use among transgender women and their male partners. Integrating socioeconomic status into gender minority stress frameworks is essential. Results have implications for substance use prevention and treatment, including the need to incorporate gender minority stressors into interventions. PMID:25642440

    2018-01-01

    To evaluate inter-reader performance for cross-sectional area and fat quantification of bilateral sciatic nerves on MRI and assess correlations with anthropometrics. In this IRB-approved, HIPPA-compliant study, three readers performed a cross-sectional analysis of 3T lumbosacral plexus MRIs over an 18-month period. Image slices were evaluated at two levels (A and B). The sciatic nerve was outlined using a free hand region of interest tool on PACS. Proton-density fat fraction (FF) and cross-sectional areas were recorded. Inter-reader agreement was assessed using intra-class correlation coefficient (ICC). Spearman correlation coefficients were used for correlations with age, BMI and height and Wilcoxon rank sum test was used to assess gender differences. A total of 67 patients were included in this study with male to female ratio of 1:1. Inter-reader agreement was good to excellent for FF measurements at both levels (ICC=0.71-0.90) and poor for sciatic nerve areas (ICC=0.08-0.27). Positive correlations of sciatic FF and area were seen with age (p value<0.05). Males had significantly higher sciatic intraneural fat than females (p<0.05). Fat quantification MRI is highly reproducible with significant positive correlations of sciatic FF and area with age, which may have implications for MRI diagnosis of sciatic neuropathy. (orig.)

    The purpose of this study is to examine the change in brain fluorodeoxyglucose (FDG) distribution with aging. Subjects were 85 men and 116 women who had no mental abnormality and no evidence of cancer in the whole body FDG-positron emission tomography (PET) study for cancer checkup. The brain data were extracted from whole body data, and stratified according to the age: 30-39 (M: 10, F: 18), 40-49 (M: 11, F: 14), 50-59 (M: 10, F: 27), 60-64 (M: 11, F: 13), 65-69 (M: 11, F: 11), 70-74 (M: 11, F: 10), 75-79 (M: 13, F: 11), over 80 (M: 8, F: 12) years. Forties or more male and female stratified age groups were compared with each gender 30's age data using Statistical Parametric Mapping (SPM)2. In the man, the FDG activity of the bilateral temporal and frontal lobes decreased and the decreased domains were expanded with aging. But in the females, the decreased domains were complicated in 40-69 years old. Dynamic changes of sex hormones in the individual female menopause may affect the complicated results in the females. Further studies are needed to confirm it. (author)

  20. 'Important… but of low status': male education leaders' views on gender in medicine.

    Risberg, Gunilla; Johansson, Eva E; Hamberg, Katarina

    2011-06-01

    The implementation of and communication about matters associated with gender in medical education have been predominantly perceived as women's issues. This study aimed to explore attitudes towards and experiences of gender-related issues among key male members of faculties of medicine. We conducted semi-structured interviews with 20 male education leaders from the six medical schools in Sweden. The interviews were analysed qualitatively using a modified grounded theory approach. The core category--'important… but of low status'--reflects ambivalent attitudes towards gender-related issues in medicine among male education leaders. All informants were able to articulate why gender matters. As doctors, they saw gender as a determinant of health and, as bystanders, they had witnessed inequalities and the wasting of women's competence. However, they had doubts about gender-related issues and found them to be overemphasised. Gender education was seen as a threat to medical school curricula as a consequence of the time and space it requires. Gender-related issues were considered to be unscientifically presented, to mostly concern women's issues and to tend to involve 'male bashing' (i.e. gender issues were often labelled as ideological and political). Interviewees asked for facts and knowledge, but questioned specific lessons and gender theory. Experiences of structural constraints, such as prejudice, hierarchies and homosociality, were presented, making gender education difficult and downgrading it. The results indicate that male faculty leaders embrace the importance of gender-related issues, but do not necessarily recognise or defend their impact on an area of significant knowledge and competence in medicine. To change this and to engage more men in gender education, faculty measures are needed to counteract prejudice and to upgrade the time allocation, merits and status of gender implementation work. Based on our findings, we present and discuss possible ways to

  1. Auditory brainstem response in neonates: influence of gender and weight/gestational age ratio

    2013-12-01

    Full Text Available OBJECTIVE: To investigate the influence of gender and weight/gestational age ratio on the Auditory Brainstem Response (ABR in preterm (PT and term (T newborns. METHODS: 176 newborns were evaluated by ABR; 88 were preterm infants - 44 females (22 small and 22 appropriate for gestational age and 44 males (22 small and 22 appropriate for gestational age. The preterm infants were compared to 88 term infants - 44 females (22 small and 22 appropriate for gestational age and 44 males (22 small and 22 appropriate for gestational age. All newborns had bilateral presence of transient otoacoustic emissions and type A tympanometry. RESULTS: No interaural differences were found. ABR response did not differentiate newborns regarding weight/gestational age in males and females. Term newborn females showed statistically shorter absolute latencies (except on wave I than males. This finding did not occur in preterm infants, who had longer latencies than term newborns, regardless of gender. CONCLUSIONS: Gender and gestational age influence term infants' ABR, with lower responses in females. The weight/gestational age ratio did not influence ABR response in either groups.

  2. Event-related potentials for gender discrimination: an examination between differences in gender discrimination between males and females.

    2008-09-01

    The event-related potentials (ERP) following presentation of male and female faces were investigated to study differences in the gender discrimination process. Visual stimuli from four categories including male and female faces were presented. For the male subjects, the P220 amplitude of the T5 area following viewing of a female face was significantly larger than that following viewing of a male face. On the other hand for female subjects, the P170 amplitude of the Cz area following observation of a male face was larger than that for a female face. The results indicate that the neural processes, including responsive brain areas used for gender discrimination by observing faces, are different between males and females.

  3. Male Iranian adolescent's reasons for having an other-gender friend.

    Bahrami, Nasim; Simbar, Masoumeh; Vedadhir, AbouAli; Bukowski, William M; Panarello, Bianca

    2016-01-21

    The aim of this study was to identify the primary reasons why male Iranian adolescents enter into other-gender friendships. A qualitative study was conducted with a sample of 21 male adolescents recruited in public places in Tehran, Iran. Information about each boy's experiences with other-gender friends was collected via semi-structured interviews whose contents were analyzed with a conventional qualitative content analysis approach. Five reasons were identified for engaging in other-gender friendships: (a) for the purpose of entertainment, (b) financial benefits, (c) increased popularity with peers, (d) sensation seeking and (e) sexual experiences. This study revealed that adolescent males do not follow appropriate goals for communicating with the other-gender. In many cases, these goals could endanger their own health and the health of their other-gender friends. Future researchers must focus on identifying and understanding the factors that influence an adolescent to enter into an other-gender friendship.

    2012-09-01

    Full Text Available The main objective of the present study is to investigate the impact of gender as well as age on the choice of forms of address in Persian. The hypothesis is that variation in the forms of address is related not only to gender of the interlocutors but also to the age of them. For this study, 30 university students- 15 males and 15 females- participated in this process that all of them were asked to fill out a questionnaire presented in the appendix. The results of the data analysis indicate that both men and women use address forms of formality (Šoma more frequently in addressing the older people from both genders that shows age is more significant than gender in determining the pronouns in address system of Persian.

  6. Old age and gender influence the pharmacokinetics of inhaled manganese sulfate and manganese phosphate in rats

    Dorman, David C.; McManus, Brian E.; Marshall, Marianne W.; James, R. Arden; Struve, Melanie F.

    2004-01-01

    In this study, we examined whether gender or age influences the pharmacokinetics of manganese sulfate (MnSO 4 ) or manganese phosphate (as the mineral form hureaulite). Young male and female rats and aged male rats (16 months old) were exposed 6 h day -1 for 5 days week -1 to air, MnSO 4 (at 0.01, 0.1, or 0.5 mg Mn m -3 ), or hureaulite (0.1 mg Mn m -3 ). Tissue manganese concentrations were determined in all groups at the end of the 90-day exposure and 45 days later. Tissue manganese concentrations were also determined in young male rats following 32 exposure days and 91 days after the 90-day exposure. Intravenous 54 Mn tracer studies were also performed in all groups immediately after the 90-day inhalation to assess whole-body manganese clearance rates. Gender and age did not affect manganese delivery to the striatum, a known target site for neurotoxicity in humans, but did influence manganese concentrations in other tissues. End-of-exposure olfactory bulb, lung, and blood manganese concentrations were higher in young male rats than in female or aged male rats and may reflect a portal-of-entry effect. Old male rats had higher testis but lower pancreas manganese concentrations when compared with young males. Young male and female rats exposed to MnSO 4 at 0.5 mg Mn m -3 had increased 54 Mn clearance rates when compared with air-exposed controls, while senescent males did not develop higher 54 Mn clearance rates. Data from this study should prove useful in developing dosimetry models for manganese that consider age or gender as potential sensitivity factors

  7. Crossing the gender boundaries: The gender experiences of male nursing students in initial nursing clinical practice in Taiwan.

    Liu, Hsing-Yuan; Li, Yun Ling

    2017-11-01

    The initial nursing clinical practice is the necessary practicum required for nursing students. Because of the changing learning style, many of them are under great pressure for environmental change and therefore their daily routine is severe affected. Interacting directly with patients in a female-dominated occupation, along with the general gender stereotypes, the impact is especially significant to male nursing students than to female nursing students. The purpose of this preliminary qualitative study is to explore the gendered experiences of male nursing students during their first initial nursing clinical practice. Both focus group interviews and individual interviews are conducted with twenty-two sophomore nursing students from a university of technology in northern Taiwan, with ten male students and twelve female students. Two main themes emerge from the gendered experiences shared by the nursing students: Gender consciousness awakening and thus maintaining masculinity, and male advantage in the learning environments. The results identify the specific gendered experiences of nursing students, providing implications for future nursing education and counseling service. Further, this study may serve to promote an active yet gender-sensitive nursing education for training nursing professionals. Published by Elsevier Ltd.

  9. Identity, gender, and the role of age of acquisition in face processing

    Andrew W. Ellis

    2009-01-01

    Full Text Available Two experiments examined the effects of age of acquisition (AoA and the gender of stimulus faces on familiarity decisions (Experiment 1 and gender decisions (Experiment 2 to the same set of famous and unfamiliar faces presented as whole faces, internal features or external features. In Experiment 1, familiarity decisions were faster to whole faces than to internal or external features. Famous faces with early AoA were recognised faster than later acquired faces, though the effect was only reliable for famous male faces, and for whole faces and internal features rather than for external features. In Experiment 2, gender decisions were made more rapidly to whole faces than to internal or external features. Classification was faster to famous than to unfamiliar faces when the faces were presented as internal features or external features, but not when they were presented as whole faces. More gender classification errors were made to famous than to unfamiliar male faces, but there was no effect of familiarity on the accuracy of responses to female faces. AoA had no effect on gender classification of whole faces or external features. Classification from internal features was faster for early than for late acquired male faces, but faster for late than for early female faces. In the light of the anomalous results for female faces, responses to male faces were analysed separately. The results for the male faces form the focus of the discussion.

  10. Gender Differences in Symptom Reporting on Baseline Sport Concussion Testing Across the Youth Age Span.

    Moser, Rosemarie Scolaro; Olek, Lauren; Schatz, Philip

    2018-02-06

    Little is known regarding gender differences in concussion symptom reporting developmentally across the age span, specifically in pre-adolescent athletes. The present study asks: Do boys and girls differ in symptom reporting across the pre-adolescent to post-adolescent age span? This retrospective study utilized baseline assessments from 11,695 10-22 year-old athletes assigned to 3 independent groups: Pre-adolescent 10-12 year olds (n = 1,367; 12%), Adolescent 13-17 year olds (n = 2,974; 25%), and Late Adolescent 18-22 year olds (n = 7,354; 63%). Males represented 60% of the sample. Baseline ImPACT composite scores and Post-Concussion Symptom Scale scores (Total, Physical, Cognitive, Emotional, Sleep) were analyzed for the effects of age and gender. Statistically significant main effects were found for age and gender on all ImPACT composites, Total Symptoms, and Symptom factors. Significant interaction effects were noted between age and gender for all ImPACT composites, Total Symptoms, and Symptom factors. Total Symptoms and all Symptom factors were highest in adolescents (ages 13-17) for males and females. In the 10-12 age group, females displayed lower Total Symptoms, Physical, and Sleep factors than males. The notion of females being more likely than males to report symptoms does not appear to apply across the developmental age span, particularly prior to adolescence. Females show greater emotional endorsement across the youth age span (10-22 years). Adolescence (13-17 years) appears to be a time of increased symptomatology that may lessen after the age of 18. © The Author(s) 2018. Published by Oxford University Press. All rights reserved.

    2005-11-01

    After studying this article, the participant should be able to discuss: 1. The terminology related to male-to-female gender dysphoria. 2. The different theories regarding cause, epidemiology, and treatment of gender dysphoria. 3. The surgical goals of sex reassignment surgery in male-to-female transsexualism. 4. The surgical techniques available for sex reassignment surgery in male-to-female transsexualism. Gender identity disorder (previously "transsexualism") is the term used for individuals who show a strong and persistent cross-gender identification and a persistent discomfort with their anatomical sex, as manifested by a preoccupation with getting rid of one's sex characteristics, or the belief of being born in the wrong sex. Since 1978, the Harry Benjamin International Gender Dysphoria Association (in honor of Dr. Harry Benjamin, one of the first physicians who made many clinicians aware of the potential benefits of sex reassignment surgery) has played a major role in the research and treatment of gender identity disorder, publishing the Standards of Care for Gender Dysphoric Persons. The authors performed an overview of the terminology related to male-to-female gender identity disorder; the different theories regarding cause, epidemiology, and treatment; the goals expected; and the surgical technique available for sex reassignment surgery in male-to-female transsexualism. Surgical techniques available for sex reassignment surgery in male-to-female transsexualism, with advantages and disadvantages offered by each technique, are reviewed. Other feminizing nongenital operative interventions are also examined. This review describes recent etiopathogenetic theories and actual guidelines on the treatment of the gender identity disorder in male-to-female transsexuals; the penile-scrotal skin flap technique is considered the state of the art for vaginoplasty in male-to-female transsexuals, whereas other techniques (rectosigmoid flap, local flaps, and isolated skin

  13. "Man-some": A Review of Male Facial Aging and Beauty.

    Keaney, Terrence Colin

    2017-06-01

    Gender plays a significant role in determining facial anatomy and behavior, both of which are key factors in the aging process. Understanding the pattern of male facial aging is critical when planning aesthetic treatments on men. Men develop more severe rhytides in a unique pattern, show increased periocular aging changes, and are more prone to hair loss. What also needs to be considered when planning a treatment is what makes men beautiful or "man-some". Male beauty strikes a balance between masculine and feminine facial features. A hypermasculine face can have negative associations. Men also exhibit different cosmetic concerns. Men tend to focus on three areas of the face - hairline, periocular area, and jawline. A comprehensive understanding of the male patient including anatomy, facial aging, cosmetic concerns, and beauty are needed for successful cosmetic outcomes.

    Age is a determinant of the gap between U.S. men's and women's work wages; young men are paid more as they age because of age; young women are not. Data from the National Longitudinal Surveys of the Labor Market Experience were analyzed for 5,225 men and 5,159 women. (KC)

  18. Gender differences in the relative age effect among US olympic development program youth soccer players.

    Vincent, John; Glamser, Francis D

    2006-04-01

    A large body of research has shown that a disproportionate number of elite youth male soccer players competing in age-segmented competition are born early in the selection year. The advantage of being born early in a cohort has been termed the "relative age effect". Although there has been an exponential growth in women's soccer, few studies have examined the relative age effect in female youth soccer. This study compared the relative age effect of 1,344 female and male youth soccer players considered by the US Olympic Development Program (ODP), in 2001, to be the most talented soccer players born in 1984. The birth dates were taken from the women's state and regional ODP, and national team rosters, and were analysed using basic descriptive statistics and chi-square tests. Results revealed only a marginal relative age effect for female ODP regional and national team players and no relative age effect for female ODP state team players. In comparison, a strong relative age effect was found in male state, regional and national team players. The results suggest that there are gender differences in the relative age effect of 17-year-old elite female and male soccer players. The gender differences may be explained by a complex interaction of biological and maturational differences with socialization influences.

    Highlights: • An effect of gender and age structure on municipal waste generation was presented. • The waste accumulation index is influenced by a number of unemployed women. • Greater share of women in society contributes to greater waste production. • A model describing the analyzed dependences was determined. - Abstract: In this study the effect of gender and age structure on municipal waste generation was investigated. The data from 10-year period, from 2001 to 2010 year, were taken into consideration. The following parameters of gender and age structure were analyzed: men and woman quantity, female to male ratio, number of working, pre-working and post-working age men/women, number of unemployed men/women. The results have showed a strong correlation of annual per capita waste generation rate with number of unemployed women (r = 0.70) and female to male ratio (r = 0.81). This indicates that waste generation rate is more depended on ratio of men and women that on quantitative size of each group. Using the regression analysis a model describing the dependence between female to male ratio, number of unemployed woman and waste quantity was determined. The model explains 70% of waste quantity variation. Obtained results can be used both to improve waste management and to a fuller understanding of gender behavior

    Research and theorizing on gender and age differences in self-esteem have played a prominent role in psychology over the past 20 years. However, virtually all empirical research has been undertaken in the United States or other Western industrialized countries, providing a narrow empirical base from which to draw conclusions and develop theory. To broaden the empirical base, the present research uses a large Internet sample (N = 985,937) to provide the first large-scale systematic cross-cultural examination of gender and age differences in self-esteem. Across 48 nations, and consistent with previous research, we found age-related increases in self-esteem from late adolescence to middle adulthood and significant gender gaps, with males consistently reporting higher self-esteem than females. Despite these broad cross-cultural similarities, the cultures differed significantly in the magnitude of gender, age, and Gender × Age effects on self-esteem. These differences were associated with cultural differences in socioeconomic, sociodemographic, gender-equality, and cultural value indicators. Discussion focuses on the theoretical implications of cross-cultural research on self-esteem. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    2007-01-01

    In this study, we investigated gender differences in age-related declines in regional cerebral glucose metabolism using FDG-PET in a large population sample with a broad age range. 230 healthy subjects (90 male; age: 34-80 y, 140 females; age: 33-82 y) participated. Correlation maps showing age related declines in glucose uptake were created separately for each gender in SPM2. Using population-based probabilistic volume of interests (VOIs), VOIs were defined for the regions showing significant decline with aging. Age related declines were separately assessed within each age range using analysis of covariate in SPSS 13.0. In the total population without gender effect, age-related negative correlation of glucose metabolism was found in the bilateral inferior frontal gyri, bilateral caudate, bilateral thalamus, left insula, left superior frontal gyrus, left uncus, right superior temporal gyrus, right medial frontal gyrus, right parahippocampal gyrus, right anterior cingulate gyrus (P < 0.001 corrected, extent threshold k = 100). 14 VOIs values of brain regions were calculated based on this negative correlation results. The rate of decline across all defined VOIs assessed in the age category of 'more than 70' referenced to the category of '30- 39years' were 7.85% in the entire sample; 7.62% in male and 8.09% in female. Detailed analyses of declines in each age range showed separable patterns of declines across gender. In males, greater decline was observed after the age 60 (20.45%) than the ages of 30 and 50(7.98%). Whereas in females, greater declines were found in age 60s (20.15%) compared to 50s, and in 40(14.84%) compared to 30s. Age-related decline in cerebral glucose metabolism was found in both genders. We further observed that males show a relatively constant pattern of decline across a life span; whereas, females show a pattern of steep changes aging to 60s and to 40s, which may be related to changes in sex hormone levels after menopause

    1998-01-01

    BACKGROUND: The risk of recurrence in affective disorder has been found to increase with each new episode. It is unclear whether it is universal without regard to gender, age and type of disorder. METHOD: Survival analysis was used to estimate the risk of recurrence in a case-register study...... episodes regardless of the combination of gender, age and type of disorder. Initially in the course of illness, unipolar and bipolar women experienced an equal greater risk of recurrence than men. The risk of recurrence after the first episode was increased for middle-aged and older unipolar women compared...... with the risk for younger women, while after all other episodes younger age at first episode increased the risk of recurrence. CONCLUSIONS: The course of severe unipolar and bipolar disorder seems to be progressive in nature irrespective of gender, age and type of disorder....

  11. Syndemics and gender affirmation: HIV sexual risk in female-to-male trans masculine adults reporting sexual contact with cisgender males.

    Reisner, Sari L; White Hughto, Jaclyn M; Pardee, Dana; Sevelius, Jae

    2016-10-01

    Female-to-male trans masculine adults who have sex with cisgender (non-transgender) males (TMSM) represent an understudied population in relation to HIV/sexually transmitted infection (STI) risk. This study examined the role of syndemic conditions and social gender affirmation processes (living full-time in one's identified gender) in potentiating sexual risk among TMSM adults in Massachusetts, US. Cross-sectional data were restricted to TMSM who reported lifetime sexual behaviour with a cisgender male (n = 173; mean age = 29.4, SD = 9.6; 18.5% people of colour; 93.1% non-heterosexual identity; 56.1% hormones/surgery). Sexual risk outcomes were: lifetime STI diagnoses, three or more sexual partners in the previous six months, and condomless anal/vaginal sex at last encounter with a cisgender male. Age- and survey mode-adjusted logistic regression models regressed sexual risk outcomes on the main effect of syndemics (six indicators summed: binge drinking, substance use, depression, anxiety, childhood abuse, intimate partner violence), followed by the interaction of syndemics and social gender affirmation. Syndemics were associated with increased odds of all sexual risk indicators (adjusted odds ratios [aORs] = 1.32-1.55; p < 0.0001). Social gender affirmation moderated the association between syndemics and condomless anal/vaginal sex at last encounter with a cisgender male (p < 0.0001). Syndemics were associated with sexual risk in TMSM who had socially affirmed their gender (aOR = 1.79; 95% CI = 1.42-2.25; p < 0.001), but not among those TMSM who had not (aOR = 0.86; 95% CI = 0.63-1.19; p = 0.37). Findings suggest that syndemic pathways to sexual risk are similar for TMSM who have socially gender affirmed as for cisgender MSM. Integration of syndemics and gender affirmation frameworks is recommended in interventions to address TMSM sexual risk. © The Author(s) 2016.

    Male-to-Female Gender Identity Disorder (MtF GID) is a complex phenomenon that could be better evaluated by using a dimensional approach. To explore the aggregation of clinical manifestations of MtF GID in order to identify meaningful variables describing the heterogeneity of the disorder. A consecutive series of 80 MtF GID subjects (mean age 37 +/- 10.3 years), referred to the Interdepartmental Center for Assistance Gender Identity Disorder of Florence and to other Italian centers from July 2008 to June 2009, was studied. Diagnosis was based on formal psychiatric classification criteria. Factor analysis was performed. Several socio-demographic and clinical parameters were investigated. Patients were asked to complete the Bem Sex Role Inventory (BSRI, a self-rating scale to evaluate gender role) and Symptom Checklist-90 Revised (SCL-90-R, a self-rating scale to measure psychological state). Factor analysis identified two dimensional factors: Factor 1 was associated with sexual orientation, and Factor 2 related to behavioral and psychological correlates of early GID development. No correlation was observed between the two factors. A positive correlation between Factor 2 and feminine BSRI score was found, along with a negative correlation between Factor 2 and undifferentiated BSRI score. Moreover, a significant association between SCL-90-R Phobic subscale score and Factor 2 was observed. A variety of other socio-demographic parameters and clinical features were associated with both factors. Behavioral and psychological correlates of Factor 1 (sexual orientation) and Factor 2 (gender identity) do not constitute the framework of two separate clinical entities, but instead represent two dimensions of the complex MtF GID structure, which can be variably intertwined in the same subject. By using factor analysis, we offer a new approach capable of delineating a psychopathological and clinical profile of MtF GID patients.

    2014-01-01

    Objective: To underline the status of male gender and gall bladder wall thickness as significant risk factors for acute cholecystitis complications. Methods: The retrospective study, with purposive sampling of the patients of acute cholecystits in age above 18 years, who were operated within 10 days of onset of symptoms, was conducted at the Department of Surgery, Dow University Hospital, Karachi, by reviewing the patients' medical record from March 2010 to August 2012. Correlation of incidence of acute cholecystitis complications (empyema and gangrene) to male gender and to the sonographic gall bladder wall thickness more than 4.5mm was analysed using SPSS 16. Result: Out of 62 patients, 8 (13%) patients had gangrene while 10 (16.12%) had empyema. Overall, there were 21 (33.87%) males in the study. Ten (47.6%) of the male patients developed empyema or gangrene of the gall bladder as a complication of acute cholecystitis. Of the 41 (66.12%) female patients, only 8 (19.5%) developed these complications. There were 22 (35.48%) cases of gall bladders with sonographic wall thickness more than 4.5mm who were operated for acute cholecystitis. Of them, 16 (72.7%) had empyema or gangrene. Conclusion: Male gender and sonographic gall bladder wall thickness more than 4.5mm were statistically significant risk factors for suspicion of complicated acute cholecystitis (empyema/gangrene) and by using these risk factors, we can prioritise patients for surgery in the emergency room.

    The present study examined the effects of age (20s to 70s), gender (male and female), and hand (dominant and nondominant) on force control capabilities (FCCs) in four force control phases (initiation, development, maintenance, and termination). Normative data of FCCs by force control phase are needed for various populations in age and gender to identify a type of motor performance reduction and its severity. FCCs of 360 participants (30 for each combination of age group and gender) were measured using a finger dynamometer and quantified in terms of initiation time (IT), development time (DT), maintenance error (ME), and termination time (TT). Although gradual increases (1%~28%) by age were shown in IT, DT, and TT, a dramatic increase in ME was observed among participants in their 50s (26%), 60s (68%), and 70s (160%) compared to those in their 20s~40s. The most distinctive interaction effect of age and gender was found in ME out of the four FCC measures. Lastly, hand and its related interactions were not found significant. Normative FCC data were established for four age groups (20s~40s, 50s, 60s, and 70s) and gender. The normative FCC data can be used for evaluating an individual's motor performance, screening patients with brain disorders, and designing input devices triggered and/or operated by the finger. © 2015, Human Factors and Ergonomics Society.

  15. Neuronal Function in Male Sprague Dawley Rats During Normal Ageing.

    Idowu, A J; Olatunji-Bello, I I; Olagunju, J A

    2017-03-06

    During normal ageing, there are physiological changes especially in high energy demanding tissues including the brain and skeletal muscles. Ageing may disrupt homeostasis and allow tissue vulnerability to disease. To establish an appropriate animal model which is readily available and will be useful to test therapeutic strategies during normal ageing, we applied behavioral approaches to study age-related changes in memory and motor function as a basis for neuronal function in ageing in male Sprague Dawley rats. 3 months, n=5; 6 months, n=5 and 18 months, n=5 male Sprague Dawley Rats were tested using the Novel Object Recognition Task (NORT) and the Elevated plus Maze (EPM) Test. Data was analyzed by ANOVA and the Newman-Keuls post hoc test. The results showed an age-related gradual decline in exploratory behavior and locomotor activity with increasing age in 3 months, 6 months and 18 months old rats, although the values were not statistically significant, but grooming activity significantly increased with increasing age. Importantly, we established a novel finding that the minimum distance from the novel object was statistically significant between 3 months and 18 months old rats and this may be an index for age-related memory impairment in the NORT. Altogether, we conclude that the male Sprague Dawley rat show age-related changes in neuronal function and may be a useful model for carrying out investigations into the mechanisms involved in normal ageing.

  16. Gender differences in episodic memory and visual working memory including the effects of age.

    Pauls, Franz; Petermann, Franz; Lepach, Anja Christina

    2013-01-01

    Analysing the relationship between gender and memory, and examining the effects of age on the overall memory-related functioning, are the ongoing goals of psychological research. The present study examined gender and age group differences in episodic memory with respect to the type of task. In addition, these subgroup differences were also analysed in visual working memory. A sample of 366 women and 330 men, aged between 16 and 69 years of age, participated in the current study. Results indicate that women outperformed men on auditory memory tasks, whereas male adolescents and older male adults showed higher level performances on visual episodic and visual working memory measures. However, the size of gender-linked effects varied somewhat across age groups. Furthermore, results partly support a declining performance on episodic memory and visual working memory measures with increasing age. Although age-related losses in episodic memory could not be explained by a decreasing verbal and visuospatial ability with age, women's advantage in auditory episodic memory could be explained by their advantage in verbal ability. Men's higher level visual episodic memory performance was found to result from their advantage in visuospatial ability. Finally, possible methodological, biological, and cognitive explanations for the current findings are discussed.

    2013-06-01

    The purposes of this study were to examine age and gender differences in throwing performance across an underexplored portion of the lifespan: middle adolescents (14-17 years old), young adults (18-25 years old), and adults (35-55 years old). Throwing performance was assessed using the body component levels from Roberton's developmental sequences for force and ball velocity that were recorded by a radar gun. Participants in each age group performed between 5 to 10 forceful overhand throws toward a target approximately 15m to 20m from the thrower. A Wilcoxon-Mann-Whitney Test was used to determine gender differences and a Wilcoxon-Signed Ranks Test was used to determine age-group differences for each component. Gender and age-group differences in ball speed were determined by a 3 (age group) x 2 (gender) factorial analysis of variance with follow-up post-hoc tests. Young-adult men had higher body component levels and ball speed compared with the adolescent boys and adult men. Female age-group differences existed only for humerus action between young-adult and adult groups and for ball speed between young-adult and adolescent groups. Gender differences (p < .01) existed in component levels for the adolescent and young-adult groups, but not the adult groups. Gender differences in ball speed (p < .001) existed within each age group. Although these data were cross-sectional, the regressive developmental changes observed and the narrowing gender gap may eventually provide insight related to the relationships among motor skill competence, physical fitness, and physical activity across the lifespan.

  19. Gender in ice hockey: women in a male territory.

    Gilenstam, K; Karp, S; Henriksson-Larsén, K

    2008-04-01

    This study investigates how female ice hockey players describe and explain their situation within as well as outside their sport. Information was obtained by semi-structured interviews with female ice hockey players. The results were analyzed in a gender perspective where the main starting point was the concepts of different levels of power relations in society developed by Harding and applied to sports by Kolnes (the symbolic, structural, and individual level). The study shows that the players appeared to share the traditional views of men and women. They also described gender differences in terms of financial and structural conditions as well as differences in ice hockey history. Even though the players described structural inequalities, they were quite content with their situation and the differences in conditions were not considered when they explained the gender differences in ice hockey performance. At the individual level, the players considered themselves different from other women and appeared to share the traditional views of femininity and masculinity. It has been suggested that performance of a sport traditionally associated with the other sex might alter the traditional view of men and women; however, our results lend little support to this suggestion.

  20. Perceptions of parental behavior with regard to parents’ gender and respondents’ age and gender

    Opsenica-Kostić Jelena

    2010-01-01

    Full Text Available The findings of the research into the perceived parental behavior provide contrasting data as to the existence and the nature of differences in the perception of parental behavior based on parents’ gender and respondents’ gender. The purpose of the present study is to examine the differences in the perceived parental behavior in adolescents with regard to parents’ gender and respondents’ age and gender. The study included 466 respondents (262 girls and 204 boys, in middle to late adolescence, divided into four sub-groups according to their age. The respondents were asked to fill in the Parental Bonding Instrument (PBI questionnaire which measures the care and overprotection in mothers and fathers respectively. The obtained findings show the existence of significant difference based on the parents’ gender for both subscales: both maternal care and maternal overprotection were estimated as higher. Observing the differences by respondents’ gender on the whole sample, only one significant difference is found: paternal overprotection was estimated as higher by girls. The differences by age as observed within gender groups are completely disparate for girl and boy groups. The best insight into the differences is obtained through analysis by gender, for groups relatively homogenous in terms of their age (for the first three groups the only significant difference appears in the paternal overprotection subscale; the difference disappears in the subgroup of the oldest respondents’, while the differences between the perception of maternal and paternal care are of significance here. One particularly important finding for future research into rearing behavior is the fact that the perception of parental behavior changes over the period of adolescence differently for boys and girls; therefore, the analysis including perceived parental behavior should be performed for subgroups by gender, which are as homogenous as possible in terms of their age.

    Full Text Available Aim. To evaluate the ability of five clinimetric instruments to discriminate between subjects >60 years of age living at home versus those living in a residency.Methods. Trained nutritionists applied five instruments (Cognition/ Depression/ Functionality/ Nutrition/ Appetite to 285 subjects with majorities of women (64%, aged <80y (61% and home residents (54%.Results. Multivariable regression models were generated for each instrument using age, gender and residency as independent variables. Age was associated with worsening scores in the five instruments whereas residency showed association in three instruments, and gender in two. Score-age regressions by place of residency showed differences suggesting that Mundet residents had increasingly worse scores with increasing age, than home dwellers for Cognition, Depression and Nutrition. Also, living at home prevented the worsening of Depression with increasing age. In contrast, Functionality and Appetite deteriorated at a similar rate for home and Mundet residents suggesting an inhability of these two instruments to dicriminate between settings. Score-age regressions by gender suggested males have less cognitive problems at 60 and 80 years of age but not at 100, and better appetite than women at all ages.Conclusions. Increasing age proved to be associated to worsening scores in the five instruments but only three were able to detect differences according to setting. An interesting observation was that living at home appeared to prevent the Depression increase with increasing age seen in Mundet residents.

    The evolution of mating signals is closely linked to sexual selection. Acoustic ornaments are often used as secondary sexual traits that signal the quality of the signaller. Here we show that song performance reflects age and reproductive success in the rock sparrow (Petronia petronia...... nests. Older males could be distinguished from yearlings by singing at lower rate and higher amplitudes. Our findings suggest that song rate may be used as a signal of age and together with song pitch as a signal of reproductive success in this species. Alternatively, younger and less successful males...... success. Males with higher breeding success sang at a lower rate and with a higher maximum frequency. We found also that older males gained more extra-pair young and had a higher overall breeding success, although they also differed almost significantly by having a higher loss of paternity in their own...

    2017-11-01

    Although research has documented age differences in substance use, less is known about how prevalence of substance use disorders (SUDs) vary across age and differ by gender and race/ethnicity. Time-varying effect models (TVEMs) were estimated on data from the National Epidemiologic Survey of Alcohol and Related Conditions-III (NESARC III; N=36,309), a nationally representative survey of the adult population. The sample was 44% male; 53% White, 21% Black, 19% Hispanic/Latino, 6% other race/ethnicity. Prevalence of four SUDs (alcohol, tobacco, cannabis and opioid use disorders) were flexibly estimated across ages 18-90 by gender and race/ethnicity. Estimated SUD prevalences were generally higher for men compared to women at most ages until the 70s. However, disparities by race/ethnicity varied with age, such that for most SUDs, estimated prevalences were higher for White participants at younger ages and Black participants at older ages. Results suggest relatively constant disparities by gender across age, and a crossover effect for Black and White participants. Findings demonstrate that Black individuals in midlife may be an important target of intervention programs for some substances. Copyright © 2017 Elsevier B.V. All rights reserved.

    subjects. We conduct an emotion recognition task followed by two stereotype question- naires with different genders and age groups. While recent findings (Krems et al., 2015) suggest that women are biased to see anger in neutral facial expressions posed by females, in our sample both genders assign higher...... ratings of anger to all emotions expressed by females. Furthermore, we demonstrate an effect of gender on the fear-surprise-confusion observed by Tomkins and McCarter (1964); females overpredict fear, while males overpredict surprise.......Recent studies have demonstrated gender and cultural differences in the recognition of emotions in facial expressions. However, most studies were conducted on American subjects. In this pa- per, we explore the generalizability of several findings to a non-American culture in the form of Danish...

  10. Association between psychosomatic health symptoms and common mental illness in Ghanaian adolescents: Age and gender as potential moderators.

    Glozah, Franklin N; Pevalin, David J

    2017-09-01

    Little is known about the role of age and gender in the association between psychosomatic symptoms and common mental illness in Ghanaian adolescents. This cross-sectional study examined age and gender as moderators between psychosomatic symptoms and common mental illness using data from a school-based survey ( N = 770). Males reported higher psychosomatic symptoms and common mental illness, while younger adolescents reported higher common mental illness only. Psychosomatic symptoms were positively associated with common mental illness, but age and gender did not moderate this association. Interventions aimed at reducing the prevalence rate in psychosomatic symptoms are crucial in decreasing common mental illness in Ghanaian adolescents.

  11. Racial and gender identity among Black adolescent males: an intersectionality perspective.

    Rogers, Leoandra Onnie; Scott, Marc A; Way, Niobe

    2015-01-01

    A considerable amount of social identity research has focused on race and racial identity, while gender identity, particularly among Black adolescents, remains underexamined. The current study used survey data from 183 Black adolescent males (13-16 years old) to investigate the development and relation between racial and gender identity centrality and private regard, and how these identities impact adjustment over time. It was found that dimensions of racial and gender identity were strongly correlated. Levels of racial centrality increased over time while gender centrality, and racial and gender private regard declined. In addition, racial and gender identity uniquely contributed to higher levels of psychological well-being and academic adjustment. These findings are discussed within the context of existing identity theories and intersectionality theory. © 2014 The Authors.

  12. Gender, aging, and the economics of "active aging": Setting a new research agenda.

    Paz, Amira; Doron, Israel; Tur-Sinai, Aviad

    2018-01-01

    The world is aging, and the percentages of older people are on a dramatic ascent. This dramatic demographic aging of human society is not gender neutral; it is mostly about older women. One of the key policy approaches to address the aging revolution is known as "active aging," crystalized by the WHO in 2002 by three pillars: participation, health, and security. The active aging policy has financial and economic aspects and affects both men and women. However, as argued in this article, a gender-based approach has not been adopted within the existing active aging framework. Therefore, a new gender-specific research agenda is needed, one that focuses on an interrelation between gender and different economic aspects of "active aging" from international, comparative, cultural, and longitudinal perspectives.

    2018-05-01

    Intestinal ischemia-reperfusion (I/R) is a life-threatening clinical disorder. During I/R, the microrheological parameters of blood (red blood cell deformability and aggregation) worsen, which may contribute to microcirculatory deterioration. Age and gender also have a great influence on hemorheological parameters. We aimed to investigate the gender and age-related microrheological alterations during intestinal I/R. After the cannulation of the left femoral artery, median laparotomy was performed in Crl:WI rats under general anesthesia. In the young control animals there were no other interventions (female n = 7; male n = 7). In the young (female n = 7; male n = 7) and older I/R groups (female n = 6; male n = 6), the superior mesenteric artery was clipped for 30 min, and a 120-min reperfusion period was observed afterward. Blood samples were taken before and at the 30-min ischemia, in the 30th, 60th, and 120th min of the reperfusion. Hematological parameters, erythrocyte deformability, and aggregation were determined. Hematocrit increased significantly in the younger female I/R group. Red blood cell count was higher in male and older animals. In case of white blood cell count, male animals had higher values compared with females. Platelet count elevated in the younger male and older female I/R animals. Red blood cell deformability worsened, mainly in the male and older I/R groups. Enhanced erythrocyte aggregation was seen in all groups, being more expressed in the female I/R groups. Microrheological parameters show gender and age-related differences during intestinal I/R. These observations have importance in the planning and evaluation of experimental data.

    2012-01-01

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

  15. Effects of Age and Gender on Hand Motion Tasks

    2015-01-01

    Full Text Available Objective. Wearable and wireless motion sensor devices have facilitated the automated computation of speed, amplitude, and rhythm of hand motion tasks. The aim of this study is to determine if there are any biological influences on these kinematic parameters. Methods. 80 healthy subjects performed hand motion tasks twice for each hand, with movements measured using a wireless motion sensor device (Kinesia, Cleveland Medical Devices Inc., Cleveland, OH. Multivariate analyses were performed with age, gender, and height added into the model. Results. Older subjects performed poorer in finger tapping (FT speed (r=0.593, p<0.001, hand-grasp (HG speed (r=0.517, p<0.001, and pronation-supination (PS speed (r=0.485, p<0.001. Men performed better in FT rhythm p<0.02, HG speed p<0.02, HG amplitude p<0.02, and HG rhythm p<0.05. Taller subjects performed better in the speed and amplitude components of FT p<0.02 and HG tasks p<0.02. After multivariate analyses, only age and gender emerged as significant independent factors influencing the speed but not the amplitude and rhythm components of hand motion tasks. Gender exerted an independent influence only on HG speed, with better performance in men p<0.05. Conclusions. Age, gender, and height are not independent factors influencing the amplitude and rhythm components of hand motion tasks. The speed component is affected by age and gender differences.

  16. Gender differences in human single neuron responses to male emotional faces.

    Newhoff, Morgan; Treiman, David M; Smith, Kris A; Steinmetz, Peter N

    2015-01-01

    Well-documented differences in the psychology and behavior of men and women have spurred extensive exploration of gender's role within the brain, particularly regarding emotional processing. While neuroanatomical studies clearly show differences between the sexes, the functional effects of these differences are less understood. Neuroimaging studies have shown inconsistent locations and magnitudes of gender differences in brain hemodynamic responses to emotion. To better understand the neurophysiology of these gender differences, we analyzed recordings of single neuron activity in the human brain as subjects of both genders viewed emotional expressions. This study included recordings of single-neuron activity of 14 (6 male) epileptic patients in four brain areas: amygdala (236 neurons), hippocampus (n = 270), anterior cingulate cortex (n = 256), and ventromedial prefrontal cortex (n = 174). Neural activity was recorded while participants viewed a series of avatar male faces portraying positive, negative or neutral expressions. Significant gender differences were found in the left amygdala, where 23% (n = 15∕66) of neurons in men were significantly affected by facial emotion, vs. 8% (n = 6∕76) of neurons in women. A Fisher's exact test comparing the two ratios found a highly significant difference between the two (p differences between genders at the single-neuron level in the human amygdala. These differences may reflect gender-based distinctions in evolved capacities for emotional processing and also demonstrate the importance of including subject gender as an independent factor in future studies of emotional processing by single neurons in the human amygdala.

    Haq, I.H.; Tahir, M.

    2008-01-01

    To investigate the age and gender-related differences in mitral cells of the human cadaveric olfactory bulbs. Sixty olfactory bulbs, 30 each from male and female (age 20-76 years) human cadavers divided into six groups of age and gender-wise were collected from the mortuary of the King Edward Medical University, Lahore. Mitral cells were counted and their diameter was calculated from 10 micro m thick cresyl violet stained histological sections. Statistical analysis was done using ANOVA for age-related differences and independent t-test for gender-related differences. There was significant reduction in the number of mitral cells and diameter of their nuclei with age. There was significant decrease in the number of mitral cells in males, between groups I and II (p < 0.001); II and III (p < 0.001); and I and III (p < 0.001); statistically significant decrease also occurred in females, between groups IV and V (p < 0.001); V and VI (p < 0.001); and IV and VI (p < 0.001). In most cases, the distance between individual mitral cells was seen to be much greater than in younger group. In group VI, few mitral cells were observed in the cell layer. There was also significant decrease in the diameter of mitral cell nuclei in males, between groups I and III (p < 0.001); and II and III (p < 0.010); in females, between groups IV and VI (p < 0.001); and V and VI (p < 0.001). No gender-related differences were observed. The number of mitral cells and diameter of their nuclei decreased with advancing age. (author)

  2. Multiple standards of aging: gender-specific age stereotypes in different life domains.

    Kornadt, Anna E; Voss, Peggy; Rothermund, Klaus

    2013-12-01

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

    2013-01-01

    Introduction. Gonial angle and antegonial region are important landmarks in mandible which is influenced by gender, age, and dental status. The objective of this study was to evaluate the gonial angle, antegonial angle, and antegonial depth and to investigate their relationship to gender, age group, and dental status. Materials and Methods. A total of 1060 panoramic radiographs were evaluated: the dentulous group, 854 subjects and the edentulous group, 206 subjects. The patients were grouped into six age groups of 10-years each. Gonial angle, antegonial angle, and antegonial depth were measured from panoramic radiographs. Results and Discussion. Corelation of age with gonial angle, antegonial angle and antegonial depth was not significant. Significant difference in mandibular angle was found between males and females. Males had significantly smaller antegonial angle and greater antegonial depth than females. Significant difference was found for gonial angle, antegonial angle, and antegonial depth between right and left sides of mandible. Conclusion. Gonial angle, antegonial angle, and antegonial depth can be implicated as a forensic tool for gender determination but not suitable for age determination

  4. No Girls Allowed: Women in Male-Dominated Majors Experience Increased Gender Harassment and Bias.

    Dresden, Brooke E; Dresden, Alexander Y; Ridge, Robert D; Yamawaki, Niwako

    2018-06-01

    The prevalence of gender harassment in male-dominated workforces has been well established, but little is known regarding the experiences of women in male-dominated majors within academia. The current study examines the experiences and gender-related biases of 146 male and female students in male-dominated (MD) and gender-equivalent (GE) majors. This study hypothesizes that men from MD majors, as opposed to GE majors, will exhibit more explicit and implicit bias regarding women in positions of power and authority, resulting in a higher prevalence of gender harassment towards women in MD majors. Results showed that there was no significant difference in self-reported explicit bias against women in positions of power and authority between men from MD and GE majors, but there was significantly more implicit bias among men from MD majors as opposed to GE majors. Additionally, women from MD majors experienced significantly more gender harassment than women from GE majors. Implications of these findings and suggestions to assist those working in education to combat these biases and instances of harassment are discussed.

  5. Do gender differences in audio-visual benefit and visual influence in audio-visual speech perception emerge with age?

    Magnus eAlm

    2015-07-01

    Full Text Available 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 towards more visually dominated responses.

  13. Age and gender as independent predictors of violence under the influence of alcohol in Zurich, Switzerland.

    Mica, Ladislav; Oesterle, Linda; Werner, Clément M L; Simmen, Hans-Peter

    2015-04-08

    Violent behaviour associated with alcohol consumption is frequently reported by different media. Clinical data analysing the correlation between alcohol intoxication, age, gender and violence are scarce. The aim of this study was to evaluate the influence of age, gender and blood alcohol content on violent behaviour under the influence of alcohol under central European conditions. Three hundred patients admitted to the emergency department were included into this study in the time period from January 01. to December 31. 2009. The inclusion criteria were a blood alcohol content (BAC) of ≥10 mmol/l, any traumatic injury and an age ≥16 years. Violence was defined as an evitable act committed by others leading to patient's hospitalisation. The data were compared with Wilcoxon and χ2-test for proportions. The data were considered as significant if pviolence with no correlation to blood alcohol content found. Logistic regression analysis revealed male gender and young age as an independent predictor for violence. These results clarify the relationship between alcohol, age, gender and violence and have important implications for municipal-level alcohol policies.

  14. Study of Adolescents Perceived Parenting Styles Based on their Gender and Age

    2017-12-01

    Full Text Available Parenting styles play a major role in determining the life styles of adolescents and that is why they share a special significance. The present study was done with the aim to investigate adolescents’ perceived parenting styles based on their gender and age. The study was conducted by a post-event method and with a sample size of 623 subjects (311 female and 312 male, who were selected by the multistage sampling method. Data were analyzed, after being collected by the Baumrind Parenting Styles Questionnaire, using multivariate analysis of variance. The results indicated that the main effects of gender and age are significant at 0.01 level. Parents’ interaction with boys is more authoritarian and with girls more authoritative; also compared with adolescents less than 17 years, they interact with adolescents 17 years old more permissively. The interaction effects of gender and age were significant at 0.05 level only in the permissive parenting style. This means that unlike the girls, parents use more and more the permissive parenting style along with increasing age of adolescent teenage boys. It was concluded that the interaction patterns of parents with children are not fixed and these patterns vary according to gender and age of the children.

  15. Dream content of Canadian males from adolescence to old age: An exploration of ontogenetic patterns.

    Dale, Allyson; Lafrenière, Alexandre; De Koninck, Joseph

    2017-03-01

    The present study was a first look at the ontogenetic pattern of dream content across the lifespan for men. The participants included 50 Canadian men in each of 5 age groups, from adolescence to old age including 12-17, 18-24, 25-39, 40-64, and 65-85. The last age group included 31 participants, totaling 231 males. One dream per participant was scored by two independent judges using content analysis. Trend analysis was used to determine the lifespan-developmental pattern of the dream content categories. Results demonstrated a predominance of aggressive dream imagery in the adolescent age group in line with social-developmental research. These patterns of dream imagery reflect the waking developmental patterns as proposed by social theories and recognized features of aging. Limitations and suggestions for future research, including the examining of the developmental pattern of gender differences across the lifespan, are discussed. Copyright © 2017 Elsevier Inc.

  16. Nutrient Canals of the Alveolar Process as an Anatomical Feature for Age and Gender Determination

    Prashant Gupta

    2017-01-01

    Full Text Available Introduction: Nutrient canals are anatomic structures of the alveolar bone through which neurovascular elements transit to supply teeth and supporting structures. Dental identification using nutrient canal of the mandibular alveolar process as the most compelling anatomic feature for antemortem–postmortem radiographic comparison can be potentially used in forensic identification. Aim: The aim of the present study was to investigate the correlation between the appearance of nutrient canals as a potential clue to age and gender determination. Materials and Methods: One hundred and twenty patients, 60 males and 60 females, were selected in the 11–60-year age group. Systemic disease, especially hypertension, was ruled out in the patients. Periapical radiographs were taken from mandibular anterior cuspid central incisor region because nutrient canals are commonly observed in this area. Data obtained was analyzed by SPSS software and various statistical analysis were carried out. Results: Study revealed nutrient canals to be commonly seen in females compared to males. Males had maximum canals in the age group of 21–30-year whereas females in the age group of 31–40 years had the maximum canals. Conclusion: Significant correlation was seen between the gender and nutrient canals whereas no significant correlation existed between the age and presence of nutrient canals.

    Stress at work affects more than 40 million people in the European Union - around 22% of workers - and is the second most reported work-related health problem. Gender does not seem to be a constant predictive factor for burnout: some studies showed that women suffer more from burnout than males, other studies proved that males report higher burnout scores while others did not detect any difference at all. These results may be due to gender-related stereotypes, or could even reiflect the preponderance of a specific gender in some jobs. To determine whether gender might be among the relevant variables in job burnout studies. In 2008-2009 a study on burnout was carried out in a Healthcare Trust in northern Italy. The Job Content Questionnaire (JCQ) and the Maslach Burnout Inventory (MBI) were distributed to physicians, administrative staff and auxiliary personnel of hospital departments and local services. A total of l, 604 JCQ's and 1,604 MBI's were analysed, corresponding to 37% of the distributed tests. Results of logistic regression showed that gender, shift work and a low score in relationships with superiors were significantly associated with burnout. Considering the tasks of physicians and nurses, the burnout frequency was 3.78% for physicians and 1.97% for nurses, with higher percentages in males than in females. Women with children reported an average burnout frequency that was lower than the average of the whole population studied while men with children had a double burnout frequency compared to the average. Male gender is significantly associated with a burnout condition. Moreover, our findings have shown that physicians experience an excess burnout compared to nurses although this excess did not achieve statistical significance when taking into account distribution according to gender in the two professions.

  18. Gender- and age-dependent gamma-secretase activity in mouse brain and its implication in sporadic Alzheimer disease.

    Lisa Placanica

    Full Text Available Alzheimer disease (AD is an age-related disorder. Aging and female gender are two important risk factors associated with sporadic AD. However, the mechanism by which aging and gender contribute to the pathogenesis of sporadic AD is unclear. It is well known that genetic mutations in gamma-secretase result in rare forms of early onset AD due to the aberrant production of Abeta42 peptides, which are the major constituents of senile plaques. However, the effect of age and gender on gamma-secretase has not been fully investigated. Here, using normal wild-type mice, we show mouse brain gamma-secretase exhibits gender- and age-dependent activity. Both male and female mice exhibit increased Abeta42ratioAbeta40 ratios in aged brain, which mimics the effect of familial mutations of Presenilin-1, Presenlin-2, and the amyloid precursor protein on Abeta production. Additionally, female mice exhibit much higher gamma-secretase activity in aged brain compared to male mice. Furthermore, both male and female mice exhibit a steady decline in Notch1 gamma-secretase activity with aging. Using a small molecule affinity probe we demonstrate that male mice have less active gamma-secretase complexes than female mice, which may account for the gender-associated differences in activity in aged brain. These findings demonstrate that aging can affect gamma-secretase activity and specificity, suggesting a role for gamma-secretase in sporadic AD. Furthermore, the increased APP gamma-secretase activity seen in aged females may contribute to the increased incidence of sporadic AD in women and the aggressive Abeta plaque pathology seen in female mouse models of AD. In addition, deceased Notch gamma-secretase activity may also contribute to neurodegeneration. Therefore, this study implicates altered gamma-secretase activity and specificity as a possible mechanism of sporadic AD during aging.

    2009-08-01

    Despite the growing recognition that the clinical symptom characteristics associated with attention deficit hyperactivity disorder (ADHD) persist into adulthood in a high proportion of subjects, little is known about the persistence of neurocognitive deficits in ADHD. The objective was twofold: (1) to conduct a meta-analysis of neuropsychological studies to characterize attentional performance in subjects with adult ADHD by examining differences in ADHD versus normal control subjects; and (2) to investigate whether these differences vary as a function of age and gender. Twenty-five neuropsychological studies comparing subjects with adult ADHD and healthy controls were evaluated. Statistical effect size was determined to characterize the difference between ADHD and control subjects. Meta-regression analysis was applied to investigate whether the difference between ADHD and control subjects varied as a function of age and gender across studies. Tests measuring focused and sustained attention yielded an effect size with medium to large magnitude whereas tests of simple attention resulted in a small to medium effect size in terms of poorer attention functioning of ADHD subjects versus controls. On some of the measures (e.g. Stroop interference), a lower level of attention functioning in the ADHD group versus the controls was associated with male gender. Adult ADHD subjects display significantly poorer functioning versus healthy controls on complex but not on simple tasks of attention, and the degree of impairment varies with gender, with males displaying a higher level of impairment.

  20. Gender Variance and Sexual Orientation Among Male Spirit Mediums in Myanmar.

    Coleman, Eli; Allen, Mariette Pathy; Ford, Jessie V

    2018-05-01

    This article describes the gender identity, gender expression, and sexual orientation of male spirit mediums in Myanmar. Our analysis is based on ethnographic work, field observation, and 10 semi-structured interviews. These observations were conducted from 2010 to 2015, mostly in Mandalay, with some fieldwork in Yangon and Bagan. The focus of this investigation was specifically on achout (gender variant individuals) who were spirit mediums (nat kadaw). Semi-structured interviews explored the ways that participants understood their gender identity, gender expression, and sexuality in relation to their work as spirit mediums and broader social life. Myanmar remains quite a homophobic and transphobic culture but is undergoing rapid economic and social change. Therefore, it provides an interesting context to study how safe spaces are produced for sexual/gender minorities amidst broader social change. We find that, through the animistic belief structure, there is a growing space for gender nonconforming people, gender variant, and same-sex-oriented individuals (achout) to neutralize their stigmatized status and attain a level of respect and economic advantage. Their ability to become nat kadaw (mediums of spirits) mitigates or trumps their stigmatized status.

    2009-12-01

    A relative age effect has been identified in Masters sports (Medic, Starkes, & Young, 2007). Since gender, age, and type of sport have been found to influence the relative age effect in youth sports (Musch & Grondin, 2001), we examined how these three variables influenced possible relative age effects among Masters swimmers and track and field athletes. Using archived data between 1996 and 2006, frequency of participation entries and record-setting performances at the US Masters championships were examined as a function of an individual's constituent year within any 5-year age category. Study 1 investigated the frequency of Master athletes who participated; Study 2 examined the frequency of performance records that were set across constituent years within an age category, while accounting for the distribution of participation frequencies. Results showed that a participation-related relative age effect in Masters sports is stronger for males, that it becomes progressively stronger with each successive decade of life, and that it does not differ across track and field and swimming. In addition, a performance-related relative age effect in Masters sport seems to be stronger for swimming than track and field, but it does not differ across gender and decades of life.

    Full Text Available Traffic signs are important visual guiding signals for the safe navigation through complex road traffic. Interestingly, there is little variation in the traffic signs for cars around the world. However, remarkable variation exists for pedestrian traffic signs. Following up from an earlier study, we investigated the visual efficacy of female vs. male German Ampelmännchen pedestrian traffic signs. In a Stroop-like test, 30 subjects were presented with female and male go and no-go traffic light figures that were shown either in the corresponding or opposing color. Subjects had to indicate, based either solely on the form or the color of the figure, whether they were allowed to go. Accuracy and response times across all subjects did not differ for the female vs. male signs, indicating that Ampelfrau and Ampelmann signs have equal visual efficacy. However, subjects responded faster to signs of their own vs. the opposite gender. This preference for signs of one's own gender is in accordance with effects in social psychology described by social learning theory. An introduction of such novel traffic lights may, thus, contribute to higher compliance with the traffic sign signals.

  5. Effects of aging on the male reproductive system.

    Gunes, Sezgin; Hekim, Gulgez Neslihan Taskurt; Arslan, Mehmet Alper; Asci, Ramazan

    2016-04-01

    The study aims to discuss the effects of aging on the male reproductive system. A systematic review was performed using PubMed from 1980 to 2014. Aging is a natural process comprising of irreversible changes due to a myriad of endogenous and environmental factors at the level of all organs and systems. In modern life, as more couples choose to postpone having a child due to various socioeconomic reasons, research for understanding the effects of aging on the reproductive system has gained an increased importance. Paternal aging also causes genetic and epigenetic changes in spermatozoa, which impair male reproductive functions through their adverse effects on sperm quality and count as, well as, on sexual organs and the hypothalamic-pituitary-gonadal axis. Hormone production, spermatogenesis, and testes undergo changes as a man ages. These small changes lead to decrease in both the quality and quantity of spermatozoa. The offspring of older fathers show high prevalence of genetic abnormalities, childhood cancers, and several neuropsychiatric disorders. In addition, the latest advances in assisted reproductive techniques give older men a chance to have a child even with poor semen parameters. Further studies should investigate the onset of gonadal senesce and its effects on aging men.

  9. Age-related differences in working hours among male and female GPs: an SMS-based time use study.

    van Hassel, Daniël; van der Velden, Lud; de Bakker, Dinny; Batenburg, Ronald

    2017-12-19

    In several countries, the number of hours worked by general practitioners (GPs) has decreased, raising concern about current and impending workforce shortages. This shorter working week has been ascribed both to the feminisation of the workforce and to a younger generation of GPs who prefer more flexible working arrangements. There is, however, limited insight into how the impact of these determinants interact. We investigated the relative importance of differences in GPs' working hours in relation to gender, age, and employment position. An analysis was performed on real-time monitoring data collected by sending SMS text messages to 1051 Dutch GPs, who participated during a 1-week time use study. We used descriptive statistics, independent sample t-tests, and one-way ANOVA analysis to compare the working time of different GP groups. A path analysis was conducted to examine the difference in working time by gender, age, employment position, and their combinations. Female GPs worked significantly fewer hours than their male peers. GPs in their 50s worked the highest number of hours, followed by GPs age 60 and older. GPs younger than 40 worked the lowest number of hours. This relationship between working hours and age was not significantly different for women and men. As shown by path analysis, female GPs consistently worked fewer hours than their male counterparts, regardless of their age and employment position. The relationship between age and working hours was largely influenced by gender and employment position. The variation in working hours among GPs can be explained by the combination of gender, age, and employment position. Gender appears to be the most important predictor as the largest part of the variation in working hours is explained by a direct effect of this variable. It has previously been reported that the difference in working hours between male and female GPs had decreased over time. However, our findings suggest that gender remains a critical

  11. Plasma and serum lipidomics of healthy white adults shows characteristic profiles by subjects' gender and age.

    Masaki Ishikawa

    Full Text Available Blood is a commonly used biofluid for biomarker discovery. Although blood lipid metabolites are considered to be potential biomarker candidates, their fundamental properties are not well characterized. We aimed to (1 investigate the matrix type (serum vs. plasma that may be preferable for lipid biomarker exploration, (2 elucidate age- and gender-associated differences in lipid metabolite levels, and (3 examine the stability of lipid metabolites in matrix samples subjected to repeated freeze-thaw cycles. Using liquid chromatography-mass spectrometry, we performed lipidomic analyses for fasting plasma and serum samples for four groups (15 subjects/group of young and elderly (25-34 and 55-64 years old, respectively males and females and for an additional aliquot of samples from young males, which were subjected to repeated freeze-thaw cycles. Lysophosphatidylcholine and diacylglycerol levels were higher in serum than in plasma samples, suggesting that the clotting process influences serum lipid metabolite levels. Gender-associated differences highlighted that the levels of many sphingomyelin species were significantly higher in females than in males, irrespective of age and matrix (plasma and serum. Age-associated differences were more prominent in females than in males, and in both matrices, levels of many triacylglycerols were significantly higher in elderly females than in young females. Plasma and serum levels of most lipid metabolites were reduced by freeze-thawing. Our results indicate that plasma is an optimal matrix for exploring lipid biomarkers because it represents the original properties of an individual's blood sample. In addition, the levels of some blood lipid species of healthy adults showed gender- and age-associated differences; thus, this should be considered during biomarker exploration and its application in diagnostics.

    2014-01-01

    Previous studies have shown that major depressive patients may differ in several features according to gender, but the existence of a specific male depressive syndrome remains controversial. As part of the EPIDEP National Multisite French Study of 493 consecutive DSM-IV major depressive patients evaluated in at least two semi-structured interviews 1 month apart, 125 (27.7%) were of male gender, whereas 317 (72.3%) were female, after exclusion of bipolar I patients. Compared to women, men were more often married, had more associated mixed features, with more bipolar disorder NOS, more hyperthymic temperaments, and less depressive temperaments. Women had an earlier age at onset of depression, more depressive episodes and suicide attempts. A higher family loading was shown in men for bipolar disorder, alcohol use disorder, impulse control disorders and suicide, whereas their family loading for major depressive disorder was lower. Men displayed more comorbidities with alcohol use, impulse control, and cardiovascular disorders, with lower comorbidities with eating, anxiety and endocrine/metabolic disorders. The following independent variables were associated with male gender: hyperthymic temperament (+), alcohol use disorder (+), impulse control disorders (+), and depressive temperament (-). The retrospective design and the lack of specific tools to assess the male depressive syndrome. Study findings may lend support to the male depression syndrome concept and draw attention to the role of hyperthymic temperament, soft bipolarity as well as comorbidities as determinants of this syndrome. The latter could help recognize an entity which is probably underdiagnosed, but conveys a high risk of suicide and cardiovascular morbidity. Copyright © 2014 Elsevier B.V. All rights reserved.

  13. Gender-atypical personality or sexual behavior: What is disgusting about male homosexuality?

    Caswell, T Andrew; Sackett-Fox, Kyrsten

    2018-01-15

    Research consistently finds that homosexuality elicits strong feelings of disgust, but the reasons remain unclear. In the current research, we investigate responses to gay men who violate social norms governing the expression of gender and sexuality. Two hundred forty-three college undergraduates read a vignette about a gay male college student whose personality traits (masculine, feminine, or neutral) and sexual behavior (active vs. passive) varied and reported their affective responses to and cognitive appraisals of the target. The gay target who displayed a feminine personality elicited more disgust and was perceived as lower in gender role conformity than a gay man who displayed a masculine personality. Similarly, the gay target who assumed a passive sex role elicited more disgust and was perceived as lower in gender role conformity than a gay man who assumed an active sex role. The sexual behavior/disgust relationship was mediated by perceived gender role conformity.

  14. Gender and age differences in expressing disruptive behavior during class

    2016-01-01

    Full Text Available The article focuses on the phenomenon of school indiscipline which proved to be an important factor of disruption in the teaching process. The aims of our research were to determine whether there were gender and age differences in expressing indiscipline during a class, as well as to examine the latent space of the School Indiscipline Scale. The sample included 897 students (42.1% boys and 57.9% girls who attend elementary (46.6% or secondary (53.4% school, aged 12 - 19. The instrument used was the Scale of School Indiscipline. The results of the component analysis indicated four components: nonparticipation, aggression, defiance to authority and cheating. By applying the MANOVA test we detected gender differences in all four subscales: that girls tend to cheat or not participate in the teaching process, while boys are more inclined to aggression and authority defiance. Regarding age differences it was noted that elementary school students are more inclined to behave aggressively while secondary school students tend not to participate and cheat. Bearing in mind that knowing gender and age differences of expressing unwanted behavior in school is very important it seems that the success of any prevention programs depend, to a large extent, upon their congruence with the students with different characteristics.

  15. Gender differences in the evaluation of physical attractiveness ideals for male and female body builds.

    Salusso-Deonier, C J; Markee, N L; Pedersen, E L

    1993-06-01

    The purposes of this research were (1) to explore gender differences in the evaluation of physical attractiveness stimuli developed to represent commonly occurring real builds, (2) to identify observers' concepts of physical attractiveness ideals promoted by the media, and (3) to begin cross-validation of these stimuli as representations of observers' concepts of ideal physical attractiveness for male and female builds. Responses included (1) open-ended descriptions of ideal male and ideal female build, (2) ratings of relative attractiveness of 12 male and 15 female stimuli, (3) selections of stimulus types which best represented ideal builds, and (4) selections of stimulus types perceived to be promoted by the media. Analysis showed strong cross-validation among modes of response. Ideal male build included average/balanced type (small and medium), lean/broad-shouldered type (large), and muscular bulk type (medium). Ideal female body build included average/balanced type (small and medium) and lean/broad-shouldered type (small and medium). Gender differences were in emphasis only. Women emphasized lean/broad-shouldered and average/balanced male types. Men emphasized the muscular bulk male type. Body types perceived to be media-promoted highlighted stereotypic male muscularity and female leanness.

  16. Gender Differences in Age-Related Striatal Dopamine Depletion in Parkinson’s Disease

    2015-09-01

    Full Text Available 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.

  17. Age and gender differences in ability emotional intelligence in adults: A cross-sectional study.

    Cabello, Rosario; Sorrel, Miguel A; Fernández-Pinto, Irene; Extremera, Natalio; Fernández-Berrocal, Pablo

    2016-09-01

    The goal of the current investigation was to analyze ability emotional intelligence (EI) in a large cross-sectional sample of Spanish adults (N = 12,198; males, 56.56%) aged from 17 to 76 years (M = 37.71, SD = 12.66). Using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), which measures ability EI according to the 4 branches of the Mayer and Salovey EI model. The authors examined effects of gender on ability EI, as well as the linear and quadratic effects of age. Results suggest that gender affects the total ability EI score as well as scores on the 4 EI branches. Ability EI was greater in women than men. Ability EI varied with age according to an inverted-U curve: Younger and older adults scored lower on ability EI than middle-aged adults, except for the branch of understanding emotions. These findings strongly support the idea that both gender and age significantly influence ability EI during aging. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  18. Drivers’ Age, Gender, Driving Experience, and Aggressiveness as Predictors of Aggressive Driving Behaviour

    Full Text Available Recent years have seen a growing interest in the problem of aggressive driving. In the presentstudy two demographic variables (gender and age, two non-psychological driving-experiencerelated variables (annual mileage and legal driving experience in years and aggressiveness asa personality trait (including behavioural and affective components as psychological variableof individual differences were examined as potential predictors of aggressive driving. The aimof the study was to find out the best predictors of aggressive driving behaviour. The study wasbased on an online survey, and 228 vehicle drivers in Latvia participated in it. The questionnaireincluded eight-item Aggressive Driving Scale (Bone & Mowen, 2006, short Latvian versionof the Buss-Perry Aggression Questionnaire (AQ; Buss & Perry, 1992, and questions gainingdemographic and driving experience information. Gender, age and annual mileage predictedaggressive driving: being male, young and with higher annual driving exposure were associatedwith higher scores on aggressive driving. Dispositional aggressiveness due to anger componentwas a significant predictor of aggressive diving score. Physical aggression and hostility wereunrelated to aggressive driving. Altogether, the predictors explained a total of 28% of thevariance in aggressive driving behaviour. Findings show that dispositional aggressiveness,especially the anger component, as well as male gender, young age and higher annual mileagehas a predictive validity in relation to aggressive driving. There is a need to extend the scope ofpotential dispositional predictors pertinent to driving aggression.

  19. Effect of age, gender and exercise on salivary dehydroepiandrosterone circadian rhythm profile in human volunteers.

    2016-02-01

    There has been a lot of effort by scientists to elucidate the multi functions of the naturally occurring hormone, dehydroepiandrosterone (DHEA). However, to plan research experiments optimally, it is important first to characterize the diurnal rhythm in healthy individuals. The aim of this research was to investigate the daily circadian rhythms of DHEA among the 2 genders, and the effect of age and exercise on salivary DHEA circadian rhythms. Volunteers (20-39 and 40-60 years) were recruited for 2 studies investigating the salivary DHEA circadian rhythm. The first study looked at the effect of gender and age on DHEA levels on 2 non-consecutive days, and the second study explored the effect of exercise on DHEA circadian rhythm in males. DHEA levels were estimated by a sensitive and specific ELISA method. The results showed a clear daily circadian rhythm in salivary DHEA in all participants groups, however the profile was flatter in the older female group. There was a significant difference between age and gender groups particularly at 8.00 h. In young males DHEA reduced from 541.1 ± 101.3 (mean ± sd) at 8.00 h to 198.9 ± 90.7 pg/mL at 18.00 h; pcircadian rhythm in salivary DHEA in all participants was observed, but the profile was flatter in the older groups.

  20. Gender Differences in Human Single Neuron Responses to Male Emotional Faces

    Morgan eNewhoff

    2015-09-01

    Full Text Available Well-documented differences in the psychology and behavior of men and women have spurred extensive exploration of gender's role within the brain, particularly regarding emotional processing. While neuroanatomical studies clearly show differences between the sexes, the functional effects of these differences are less understood. Neuroimaging studies have shown inconsistent locations and magnitudes of gender differences in brain hemodynamic responses to emotion. To better understand the neurophysiology of these gender differences, we analyzed recordings of single neuron activity in the human brain as subjects of both genders viewed emotional expressions.This study included recordings of single-neuron activity of 14 (6 male epileptic patients in four brain areas: amygdala (236 neurons, hippocampus (n=270, anterior cingulate cortex (n=256, and ventromedial prefrontal cortex (n=174. Neural activity was recorded while participants viewed a series of avatar male faces portraying positive, negative or neutral expressions.Significant gender differences were found in the left amygdala, where 23% (n=15/66 of neurons in men were significantly affected by facial emotion, versus 8% (n=6/76 of neurons in women. A Fisher's exact test comparing the two ratios found a highly significant difference between the two (p<0.01. These results show specific differences between genders at the single-neuron level in the human amygdala. These differences may reflect gender-based distinctions in evolved capacities for emotional processing and also demonstrate the importance of including subject gender as an independent factor in future studies of emotional processing by single neurons in the human amygdala.

  1. Male Survivors of Sexual Abuse: Becoming Gender-Sensitive and Trauma-Informed

    Jennifer Elkins

    2017-09-01

    Full Text Available While there is a wide body of literature examining the behavioral, emotional, and social consequences associated with being sexually abused, comparatively few studies have focused on males. Sexual abuse victimization among males remains largely under-reported, under-treated, and under-recognized by researchers, practitioners, and the public. Researchers trying to clarify why sexual abuse in males has been overlooked point to prevailing cultural norms, myths, assumptions, stigma, and biases about masculinity. Consequently, there is often an assumption that males are not negatively affected by sexual abuse. Drawing extensively from the literature, this article provides a critical review of: (1 the nature, experience and impact of sexual abuse victimization for males; and (2 the multidimensional processes that promote and inhibit resilient outcomes. It concludes with a discussion of trauma-informed and gender-responsive recommendations and future directions for social work practice, policy, and research.

  2. Male gender identity in children with 46,XX DSD with congenital adrenal hyperplasia after delayed presentation in mid-childhood.

    Chowdhury, Tanvir Kabir; Laila, Kamrun; Hutson, John M; Banu, Tahmina

    2015-12-01

    Girls with congenital adrenal hyperplasia (CAH) diagnosed at birth have some masculine behaviors but rarely convert to male gender. In developing countries, however, diagnosis and treatment (with secondary androgen suppression) are delayed. We aimed to assess effect of delayed treatment of CAH on gender identity. As part of a cross-sectional, case-control study of children with disorders of sex development (DSD), there were 11 patients with CAH. Patients and caregivers answered a questionnaire about gender identity, and behavior was assessed by observing toy play. Patients were examined for Prader score and gender identity. Of 11 CAH patients initially raised as girls, 3 (27%) had converted to male gender at presentation (5, 9, 9years) (Prader 3, 4, 4). Of the remaining 8 patients, one 4-year-old (Prader 2) had a male gender identity score. The remaining girls (2-13years, mean 8.1) (Prader 1-3) had gender identity scores in the female range. One third (4/11) of CAH patients presenting in mid-childhood had male gender identity scores, and ¾ had assumed male gender role. Although social and cultural factors are important in developing countries, this result suggests that delayed treatment may trigger male gender identity, and delayed female genital surgery may be unwise.

    The present study aimed to investigate differences in personality traits among male-to-female (MtF), female-to-male (FtM) gender identity disorder (GID) subjects and non-transsexual male (M) and female (F) controls. Subjects were 72 MtF and 187 FtM GID subjects without psychiatric comorbidities together with 184 male and 159 female non-transsexual controls. Personality traits were assessed using a short version of the Temperament and Character Inventory (TCI-125). Group comparisons were made by two-way ANOVA. Statistical significances were observed as follows: 1) lower novelty seeking in FtM than in M or MtF, 2) higher reward dependence in FtM than in M, 3) higher cooperativeness in FtM than in M or MtF, 4) the highest self-transcendence in MtF among all the groups. The highest self-transcendence in MtF subjects may reflect their vulnerable identity and constrained adaptation to society as the minority. Nevertheless, higher reward dependence and cooperativeness in FtM subjects can be related to more determined motivation for the treatments of GID and might promise better social functioning and adjustment than MtF subjects.

  4. Time perspective: its link to personality traits, age, and gender

    Kairys, Antanas

    2010-01-01

    In Lithuania, as well as in other countries, psychological studies on time perspective are still making their first steps. Currently, no theoretical paradigm is extensive enough to serve well as a basis for further fundamental and applied research in this field. The goal of this study was to explore the link between time perspective and personality traits in different gender and age groups. To analyse time perspective and personality traits, two independent studies were carried out (N=636 in ...

    This retrospective study identifies risk factors for mortality in a cohort of HIV-positive adult patients treated with highly active antiretroviral therapy (HAART) in Jos, Nigeria. We analyzed clinical data from a cohort of 1552 patients enrolled in a HIV/acquired immune deficiency syndrome treatment program and started on HAART between December 2004 and 30 April 2006. Death was our study endpoint. Patients were followed in the study until death, being lost to follow-up, or the end of data collection, 1 December 2006. Baseline patient characteristics were compared using Wilcoxon Rank Sum Test for continuous variables and Pearson Chi-Square test for categorical variables to determine if certain demographic factors were associated with more rapid progression to death. The Cox proportional hazard multivariate model analysis was used to find risk factors. As of 1 December 2006, a total of 104 cases progressed to death. In addition to the expected association of CD4 count less than 50 at initiation of therapy and active tuberculosis with mortality, the patient characteristics independently associated with a more rapid progression to death after initiation of HAART were male gender, age less than 30 years old, and unemployment or unknown occupation status. Future research is needed to identify the confounding variables that may be amenable to targeted interventions aimed at ameliorating these health disparities.

Gender-role flexibility impacted…

  7. Road traffic offending, stress, age, and accident history among male and female drivers.

    Simon, F; Corbett, C

    1996-05-01

    This paper draws on data gathered during a larger study of driving behaviour to explore possible connections between stress, offending against the traffic laws, and accident rates, and gives particular attention to comparisons between male and female drivers. Data were gathered from 422 drivers by a postal questionnaire, and further measures of stress were obtained during semi-structured interviews with a specially selected subset of 66 of them. Analyses of variance investigated links between offending rates, accident history, and up to seven measures of stress, taking age and gender into account. In the results accident history, although positively related to offending, played little part in links involving stress variables. The principal findings were that (a) stress, both on and off the road, was positively associated with offending among both male and female drivers, and (b) although females overall offended less than males, females experienced more stress than males whatever their level of offending. One possible interpretation of these results is suggested by the feminist literature, which could account for both the higher levels of stress and lower levels of offending found among women drivers. However, there is unlikely to be a clear-cut gender divide in offending-stress relationships, and some small groups of female drivers in the study behaved like male ones. It is suggested that people's driving reflects their lifestyles, and that women drivers' patterns of offending and stress will resemble those of male drivers to the extent that their lives and concerns are similar to men's. It is concluded that this position warrants further research.

    Full Text Available The aim of the study was to investigate the effect of gender on the 30 m sprint performance of middle school students (10-13 ages. The study included 25 male and 25 female total 50 middle school students. The mean age of female students was found as 12,36 ± 0,48 (year, the mean body weight as 42,03 ± 3,63 (kg, and the mean height as 151,11 ±5,61 (cm, and the mean age of male students was found as 12,28 ± 0,45 (year, the mean height as 152,28 ± 5,04 (cm, and the mean body weight as 43,35 ± 1,88 (kg. The mean sprint performance of female students was calculated as 6,33 ± 0,53 seconds, and the mean sprint performance of the male students was 6,17 ± 0,47 seconds. As a result the effect of gender on sprint performance was found to be insignificant between the groups (p>0,05.

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

  11. Bullying, Physical Aggression, Gender-Atypicality, and Sexual Orientation in Samoan Males.

    Semenyna, Scott W; Vasey, Paul L

    2017-07-01

    Bullying is characterized by the repeated attempts of a group or individual to gain social advantage by the use of relational, verbal, or physical aggression against a target, especially when there is a perceived or actual power imbalance (Espelage & Swearer, 2003). One consistent finding is that gay (i.e., androphilic) males report higher rates of victimization due to bullying in adolescence than their heterosexual (i.e., gynephilic) counterparts. Western data indicate that gender-atypical behavior, regardless of sexual orientation, is a key predictor of victimization due to bullying. Androphilic males generally display childhood gender-atypicality, including reduced levels of physical aggression, which may cause bullies to perceive them as "easy" targets. In order to test the associations between sexual orientation, childhood gender-atypicality, and recalled victimization due to bullying, a sample of Samoan gynephilic men (n = 100) were compared to a group of Samoan transgender androphilic males (n = 103), known as fa'afafine. Although the fa'afafine reported far more childhood gender-atypicality, the two groups did not differ significantly on measures of physical aggression or their reported rates of victimization due to bullying. Additionally, greater physical aggression, not gender-atypicality, was the only significant predictor of being bullied in both men and fa'afafine. These results suggest that there is nothing inherent in sexual orientation or childhood gender-atypicality that would potentiate victimization from bullying. Instead, the cultural context in which a bully functions influences the extent to which these are "acceptable" reasons to target certain individuals.

    2017-10-01

    Phthalate exposure has been reported to be associated with obesity (measured by body mass index [BMI]) and central obesity (measured by waist circumference [WC]). Yet, reported associations and the potential gender and age differences are inconsistent. We conducted a cross-sectional study involving 2330 participants in the fall of 2012. Urinary metabolites of ten phthalates were measured. Height, body weight, and waist circumference (WC) were measured using standardized methods. We performed logistic regression analyses to estimate the association between each urine phthalate metabolite (categorized into quartiles) and obesity and central obesity and conducted an additional, stratified analysis to explore the gender and age differences. In the overall study population, higher urinary levels of MMP, MEHHP, and MECPP were associated with increased ratios of central obesity. When stratifying by gender and central obesity, higher urinary levels of MMP, MEHHP, and MEOHP were associated with increased odds of central obesity in females, whereas MB z P was significantly associated inversely with central obesity in females. In males, it showed no significant P value for trend (P trend). When stratifying by age in females, higher urinary levels of MEHP, MEOHP, MEHHP, and MECPP were associated with increased odds of central obesity in women aged ≤45 years. In females aged >45 years, it showed no significant P trend. In conclusion, we found that association between phthalates and central obesity was stronger than between phthalates and obesity; association between phthalates and central obesity was stronger in females than in males and was stronger in younger females (aged ≤45 years) than in older females (aged >45 years).

  16. Degrees of Intersectionality: Male Rap Artists in Sweden Negotiating Class, Race and Gender

    Kalle Berggren

    2013-01-01

    “Intersectionality” has become a highly influential concept in gender research over the last 25 years. Debates have focused on differences and power asymmetries between women, in terms of race but also addressing class, age, sexuality, ability and nation. However, intersectional paradigms have been used to a much lesser extent in gender studies on men. This article seeks to contribute to an emerging discussion about intersectionality and masculinity by analyzing rap lyrics in Swe-dish songs. ...

  17. Gender on the growth of Criollo foals from birth to three years of age

    Anelise Maria Hammes Pimentel

    Full Text Available ABSTRACT: The objective of the present study was to evaluate the effect of gender on the growth of Criollo foals, in order to use this information as a reference for breeding as well as in future research. Body height, thoracic perimeter, and cannon bone perimeter of 75 foals were measured from two farms in Rio Grande do Sul, Brazil (Lat. 32°, 33′, 58″, Long. 53°, 22′, 33″ and from three generations over three years. In both farms, animals were kept under the same range and feeding conditions. Nonlinear regression models were applied to describe the growth curves for the three traits over the experimental period. Cannon bone perimeter was greater in males than in females (P<0.001 but the predicted curves for body height and thoracic perimeter did not differ between genders. For all traits, the highest rate of increase was achieved in the first year of life (body height = 74%, thoracic perimeter = 76%, and cannon bone perimeter = 63% for males and 83% for females. Results of this study indicated that changes in body height and thoracic perimeter can be predicted using nonlinear models in both male and female foals, until they reach three years of age; whereas, changes in cannon bone perimeter should be modeled separately for each gender.

  18. Sun-induced changes of stratum corneum hydration vary with age and gender in a normal Chinese population.

    2012-02-01

    Previous studies have demonstrated that sun-induced alteration of epidermal permeability barrier function varies with gender and age. In the present study, we assess the stratum corneum (SC) hydration in sun-exposed males and females. A total of 168 subjects (84 males and 84 females) aged 19-75 years were enrolled. A multifunctional skin physiology monitor was used to measure SC hydration. In comparison with non-sun exposure, sun exposure does not cause a significant change in SC hydration in either young males or young females, whereas in aged females, a significant reduction of SC hydration is seen on the forehead and the dorsal hand of sun-exposed subjects. SC hydration on the canthus of both aged males and aged females is significantly lower than that of young subjects. Additionally, SC hydration on the dorsal hand of aged females is also significantly lower as compared with young females. Sun-induced reduction of SC hydration is more evident on the dorsal hand of aged females than that of males (Phydration property vary with age and gender. © 2011 John Wiley & Sons A/S.

  19. Assessing the influence of age and gender on the phenotype of myotonic dystrophy type 2.

    Montagnese, Federica; Mondello, Stefania; Wenninger, Stephan; Kress, Wolfram; Schoser, Benedikt

    2017-12-01

    This study aims to provide a detailed clinical characterization of a large cohort of myotonic dystrophy type 2 (DM2) patients investigating the influence of age and gender as modifying factors of DM2 phenotype. A retrospective study was conducted on 307 patients with genetically confirmed DM2. The following data were analyzed: (1) demographics, (2) clinical features (first symptom, muscular complaints, and multisystemic involvement), (3) diagnostics (serological tests, electromyography, and muscle biopsy). In this cohort (186 females, 121 males), a proximal weakness was the leading symptom at onset (55.4%), followed by myalgia (35.5%) and myotonia (25.4%). Proximal weakness was more common in women than men (64.9 vs. 43.8%, p = 0.0006), whereas being male was associated with higher odds for developing myalgia [OR 2.94 (95% CI 1.53-5.67)]. Patients with muscle weakness at onset were older than those with myalgia and myotonia (p women (p = 0.002 and p = 0.002, respectively). Early onset of DM2 is an independent risk factor for the occurrence of multisystemic involvement [OR 0.94 (95% CI 0.90-0.98)]. In this updated clinical description of DM2 emerges a profound gender and age influence on the phenotype, emphasizing that female gender and ageing may be associated with a higher disease burden. These age- and gender-specific differences should be considered in diagnostics, management, and future clinical studies of DM2.

  20. [Adolescents with gender identity disorder: reconsideration of the age limits for endocrine treatment and surgery].

    Nakatsuka, Mikiya

    2012-01-01

    The third versions of the guideline for treatment of people with gender identity disorder (GID) of the Japanese Society of Psychiatry and Neurology does not include puberty-delaying hormone therapy. It is recommended that feminizing/masculinizing hormone therapy and genital surgery should not be carried out until 18 year old and 20 year old, respectively. On the other hand, the sixth (2001) and the seventh (2011) versions of the standards of care for the health of transsexual, transgender, and gender nonconforming people of World Professional Association for Transgender Health (WPATH) recommend that transsexual adolescents (Tanner stage 2, [mainly 12-13 years of age]) are treated by the endocrinologists to suppress puberty with gonadotropin-releasing hormone (GnRH) agonists until age 16 years old, after which cross-sex hormones may be given. A questionnairing on 181 people with GID diagnosed in the Okayama University Hospital (Japan) showed that female to male (FTM) transsexuals hoped to begin masculinizing hormone therapy at age of 15.6 +/- 4.0 (mean +/- S.D.) whereas male to female (MTF) transsexuals hoped to begin feminizing hormone therapy as early as age 12.5 +/- 4.0, before presenting secondary sex characters. After confirmation of strong and persistent cross-gender identification, adolescents with GID should be treated with cross-gender hormone or puberty-delaying hormone to prevent developing undesired sex characters. These treatments may prevent transsexual adolescents from attempting suicide, being depressive, and refusing to attend school. Subsequent early breast and genital surgery may help being employed in desired sexuality.

  1. Effects of age, gender and educational background on strength of motivation for medical school.

    Kusurkar, Rashmi; Kruitwagen, Cas; ten Cate, Olle; Croiset, Gerda

    2010-08-01

    The aim of this study was to determine the effects of selection, educational background, age and gender on strength of motivation to attend and pursue medical school. Graduate entry (GE) medical students (having Bachelor's degree in Life Sciences or related field) and Non-Graduate Entry (NGE) medical students (having only completed high school), were asked to fill out the Strength of Motivation for Medical School (SMMS) questionnaire at the start of medical school. The questionnaire measures the willingness of the medical students to pursue medical education even in the face of difficulty and sacrifice. GE students (59.64 ± 7.30) had higher strength of motivation as compared to NGE students (55.26 ± 8.33), so did females (57.05 ± 8.28) as compared to males (54.30 ± 8.08). 7.9% of the variance in the SMMS scores could be explained with the help of a linear regression model with age, gender and educational background/selection as predictor variables. Age was the single largest predictor. Maturity, taking developmental differences between sexes into account, was used as a predictor to correct for differences in the maturation of males and females. Still, the gender differences prevailed, though they were reduced. Pre-entrance educational background and selection also predicted the strength of motivation, but the effect of the two was confounded. Strength of motivation appears to be a dynamic entity, changing primarily with age and maturity and to a small extent with gender and experience.

    2014-01-01

    The cervical anatomy has been shown to affect injury patterns in vehicle crashes. Characterizing the spine anatomy and changes associated with growth and gender is important when assessing occupant protection. In this study, selected cervical characteristics were quantified. Computed tomography (CT) scans of 750 patients were selected from the University of Michigan trauma database; 314 were children and 436 were adults. Four variables were obtained: the maximum spinal canal radius, vertebral body depth, facet angles, and retroversion angles. The cervical spine measurements varied with age and gender. The body depth increased nonlinearly with age. The average vertebral body depth at C4 was 9.2 ± 0.38 mm in the 0-3 age group, 15.7 ± 0.29 mm in the 18-29 age group, and 17.2 ± 0.46 mm in the 60+ age group. Pediatric and adult males had larger vertebral body depth than females overall, irrespective of vertebral level (P vertebral body depth was 8-9 percent greater in male children and 13-16 percent greater in adult males. The average radius varied with gender, with male children generally having a larger radius than females irrespective of vertebral level (P vertebral level (P maturation by the age of 7. Facet angles decreased with age in children and increased with age in adults. The average facet angles were largest in the 0-3 age group (P cervical anatomical changes associated with age and gender. The information is useful when assessing differences in injury patterns between different segments of the population. Anatomical measurements of the cervical spine should be considered for the development of models used to assess injury mechanisms for various occupant age groups.

  3. Male Prison Inmates With Gender Dysphoria: When Is Sex Reassignment Surgery Appropriate?

    Osborne, Cynthia S; Lawrence, Anne A

    2016-10-01

    Gender dysphoria (GD), a feeling of persistent discomfort with one's biologic sex or assigned gender, is estimated to be more prevalent in male prison inmates than in nonincarcerated males; there may be 3000-4000 male inmates with GD in prisons in the United States. An increasing number of U.S. prison systems now offer gender dysphoric inmates diagnostic evaluation, psychotherapy, cross-sex hormone therapy, and opportunities, albeit limited, to enact their preferred gender role. Sex reassignment surgery (SRS), however, has not been offered to inmates except in response to litigation. In the first case of its kind, the California Department of Corrections and Rehabilitation recently agreed to provide SRS to an inmate and developed policy guidelines for its future provision. In other recent cases, U.S. courts have ruled that male inmates with GD are entitled to SRS when it is medically necessary. Although these decisions may facilitate the provision of SRS to inmates in the future, many U.S. prison systems will probably remain reluctant to offer SRS unless legally compelled to do so. In this review, we address the medical necessity of SRS for male inmates with GD. We also discuss eligibility criteria and the practical considerations involved in providing SRS to inmates. We conclude by offering recommendations for physicians, mental health professionals, and prison administrators, designed to facilitate provision of SRS to inmates with GD in a manner that provides humane treatment, maximizes the likelihood of successful outcomes, minimizes risk of regret, and generates data that can help inform future decisions.

  4. Features of gender identity among schoolchildren of different ages

    2014-01-01

    Full Text Available Purpose . Gender identity manifestations in schoolchildren were investigated. Material . The study involved schoolchildren of 3 -11th forms of the secondary schools (206 – boys, 213 - girls. For the research of age peculiarities in psychological gender, a questioner worked out by Sundry Bam which consists of 60 statements was used. Results . A number of aspects of self description which have different psychological characteristics in boys and girls were analysed. A peculiarity of gender identity in schoolchildren, which was identified by the overall number of respondents in whom the androgens personality type was identified, was singled out. Out of 206 boys – 90% have an androgens index, as for the girls – 69.5% refer to androgens personality type. The presence of feminine character qualities in boys and masculine – in girls was found out, which proves maximal development of feminine and masculine in one person. This will help social adaptation of schoolchildren. Conclusions . Physical education has enormous potential emotional and physical impact on the formation of gender identity of students and their notions of femininity and masculinity. This can directly affect the formation of life value orientations students in general, including the formation of values in the sphere of physical culture.

  5. Motives for adult participation in physical activity: type of activity, age, and gender.

    Molanorouzi, Keyvan; Khoo, Selina; Morris, Tony

    2015-01-31

    In recent years, there has been a decline in physical activity among adults. Motivation has been shown to be a crucial factor in maintaining physical activity. The purpose of this study was to examine whether motives for participation could accurately discriminate gender, age, and type of physical activity. A quantitative, cross-sectional descriptive research design was employed. The Physical Activity and Leisure Motivation Scale (PALMS) was used to assess motives for physical activity in 1,360 adults (703 males, 657 females) who had been exercising regularly for at least six months. The PALMS consists of 40 items that constitute eight sub-scales (mastery, enjoyment, psychological condition, physical condition, appearance, others' expectations, affiliation, competition/ego). Respondents were divided into two age groups (young adults aged 20 to 40 years and middle-aged adults 41 to 64 years) and five types of activity (individual racing sports plus bowls, team sports, racquet sports, martial arts, and exercise). The group discriminant function analyses revealed significant canonical functions correctly classifying the cases into gender (82%), age group (83%), team sport players 76%, individual racing sport plus bowls players 91%, racquet sport players 90%, exercisers 84%, and martial art players 91%. The competition/ego, appearance, physical condition, and mastery sub-scales contributed most to gender differences. Five sub-scales (mastery, psychological condition, others' expectations, affiliation, and enjoyment) contributed most to the discriminant function for age. For type of activity, different sub-scales were the strongest contributors to the discriminant function for each type of PA. The findings in this study suggest that strong and important motives for participation in physical activity are different across type of activity, age, and gender in adults. Understanding the motives that influence physical activity participation is critical for developing

  6. Gender and Age-Dependent Etiology of Community-Acquired Urinary Tract Infections

    Enrico Magliano

    2012-01-01

    Full Text Available Urinary tract infections (UTIs are among the most frequent community-acquired infections worldwide. Escherichia coli is the most common UTI pathogen although underlying host factors such as patients’ age and gender may influence prevalence of causative agents. In this study, 61 273 consecutive urine samples received over a 22-month period from outpatients clinics of an urban area of north Italy underwent microbiological culture with subsequent bacterial identification and antimicrobial susceptibility testing of positive samples. A total of 13 820 uropathogens were isolated and their prevalence analyzed according to patient’s gender and age group. Overall Escherichia coli accounted for 67.6% of all isolates, followed by Klebsiella pneumoniae (8.8%, Enterococcus faecalis (6.3%, Proteus mirabilis (5.2%, and Pseudomonas aeruginosa (2.5%. Data stratification according to both age and gender showed E. coli isolation rates to be lower in both males aged ≥60 years (52.2%, E. faecalis and P. aeruginosa being more prevalent in this group (11.6% and 7.8%, resp., as well as in those aged ≤14 years (51.3% in whom P. mirabilis prevalence was found to be as high as 21.2%. Streptococcus agalactiae overall prevalence was found to be 2.3% although it was shown to occur most frequently in women aged between 15 and 59 years (4.1%. Susceptibility of E. coli to oral antimicrobial agents was demonstrated to be as follows: fosfomycin (72.9%, trimethoprim/sulfamethoxazole (72.9%, ciprofloxacin (76.8%, ampicillin (48.0%, and amoxicillin/clavulanate (77.5%. In conclusion, both patients’ age and gender are significant factors in determining UTIs etiology; they can increase accuracy in defining the causative uropathogen as well as providing useful guidance to empiric treatment.

  7. Convergence in Sleep Time Accomplished? Gender Gap in Sleep Time for Middle-Aged Adults in Korea.

    Cha, Seung-Eun; Eun, Ki-Soo

    2018-04-19

    Although the gender gap in sleep time has narrowed significantly in the last decade, middle-aged women between ages 35 and 60 still sleep less than their male counterparts in Korea. This study examines and provides evidence for factors contributing to the gender gap in this age group. Using Korean Time Use Survey (KTUS) data from 2004, 2009 and 2014, we find that middle-aged women’s difficulty in managing work-life balance and traditional role expectations placed upon women are the main causes of the gender gap in sleep time. The decomposition analysis reveals that the improved socioeconomic status and recent changes in familial expectations for women may have helped them sleep more than in the past. However, there remain fundamental differences in attitude and time use patterns between men and women that prevent middle-aged women from getting the same amount of sleep.

    Prolonged conflict in South Sudan exacerbated gender disparities and inequities. This study assessed differences in attitudes towards gender inequitable norms and practices by sex, age and education to inform programming. Applying community-based participatory research methodology, 680 adult respondents, selected by quota sampling, were interviewed in seven South Sudanese communities from 2009 to 2011. The verbally administered survey assessed attitudes using the Gender Equitable Men scale. Data were stratified by sex, age and education. Of 680 respondents, 352 were female, 326 were male and two did not report their sex. The majority of respondents agreed with gender inequitable household roles, but the majority disagreed with gender inequitable practices (i.e., early marriage, forced marriage and inequitable education of girls). Respondents who reported no education were more likely than those who reported any education to agree with gender inequitable practices (all p gender inequitable norms in the household but an overall disagreement with gender inequitable practices in sampled communities. The findings support that education of both women and men may promote gender equitable norms and practices.

    Objectives:To see the effects of age, gender and diabetes on serum lipid levels. Study type, settings and duration:Cross sectional analytical study conducted at PMRC Research Centre, Fatima Jinnah Medical College,Lahore from Jun-Dec 2011. Materials and Methods: One hundred type 2 diabetes mellitus and equal numbers of gender matched healthy controls were randomly selected for the study. After an overnight fasting, blood specimens were drawn for lipid profile where total cholesterol,high density lipoprotein cholesterol and triglycerides were measured by standard enzymatic endpoint methods and LDL-cholesterol by Friedweld's formula. Statistical analysis was done using SPSS-15. Results Odd ratios of age for total cholesterol (OR 1.198); high density lipoprotein cholesterol (OR 1.144); and low density lipoprotein cholesterol (OR 1.576) revealed that subjects aged 45 years or more had greater risk of having deranged lipid levels. Female gender had higher high density lipoprotein cholesterol (p 0.000); and triglycerides (p 0.001). Odd ratios of men for total cholesterol (OR 0.775); high density lipoprotein cholesterol(OR 0.183); and low density lipoprotein Cholesterol (OR 0.683) illustrated that men were significantly less prone to dyslipidemia than women. Odd ratio of diabetes for high density lipoprotein cholesterol (OR 1.802) suggested that diabetics had 1.8 times more risk of having low high density lipoprotein cholesterol. Conclusions: Diabetic females over 45 years of age have significantly high chances of having disturbed or high lipid profile. Policy message:All persons in general and diabetics in particular over the age of 45 years should be screened for dyslipidemia and informed using behavior change communication to prevent disease complications.

    The impact of race/ethnicity upon facial anthropometric data in the US workforce, on the development of personal protective equipment, has not been investigated to any significant degree. The proliferation of minority populations in the US workforce has increased the need to investigate differences in facial dimensions among these workers. The objective of this study was to determine the face shape and size differences among race and age groups from the National Institute for Occupational Safety and Health survey of 3997 US civilian workers. Survey participants were divided into two gender groups, four racial/ethnic groups, and three age groups. Measurements of height, weight, neck circumference, and 18 facial dimensions were collected using traditional anthropometric techniques. A multivariate analysis of the data was performed using Principal Component Analysis. An exploratory analysis to determine the effect of different demographic factors had on anthropometric features was assessed via a linear model. The 21 anthropometric measurements, body mass index, and the first and second principal component scores were dependent variables, while gender, ethnicity, age, occupation, weight, and height served as independent variables. Gender significantly contributes to size for 19 of 24 dependent variables. African-Americans have statistically shorter, wider, and shallower noses than Caucasians. Hispanic workers have 14 facial features that are significantly larger than Caucasians, while their nose protrusion, height, and head length are significantly shorter. The other ethnic group was composed primarily of Asian subjects and has statistically different dimensions from Caucasians for 16 anthropometric values. Nineteen anthropometric values for subjects at least 45 years of age are statistically different from those measured for subjects between 18 and 29 years of age. Workers employed in manufacturing, fire fighting, healthcare, law enforcement, and other occupational

    Full Text Available Because the decline in androgens is generally gradual and not a complete deficiency, clinical significance of this decline is still unclear, and there is controversy as to whether a specific syndrome of androgen deficiency or ′andropause′ exists. The term andropause or androgen deficiency in aging males (ADAM underwent revisions to, partial androgen deficiency in aging male (PADAM, late onset hypogonadism (LOH and now symptomatic late onset hypogonadism (SLOH, signifying, the evolving nature of this phenomenon. Since this happens at a time of life, when many men have associated comorbities, it′s difficult to assess the exact impact of androgen decline, due to which, the issues surrounding androgen replacement therapy in men with symptomatic late-onset hypogonadism have been marred in controversy. Although with age, a decline in testosterone levels will occur in virtually all men, there is no way of predicting, who, will experience andropausal symptoms of sufficient severity and also long-term safety data on testosterone administration in this setting, is lacking. This article will focus on the controversies and practices of androgen replacement.

  13. Male gender and smoking are related to single, but not to multiple, human aortic aneurysms.

    There is scanty information concerning multiple aortic aneurysms. Thus, we verified if clinical or pathological characteristics are different in patients with multiple (two or more) aortic aneurysms in comparison with those with only one. We selected at the necropsy files of the Heart Institute, São Paulo University School of Medicine, the last 100 cases with aortic aneurysms, comparing between the two groups: sex, age, presence of systemic arterial hypertension, diabetes, dyslipedemia, history of smoking habit, cause of the aneurysm, cause of death, and if the diagnosis was reached during life. Age was analysed by Mann-Whitney test, and the other variables by chi-square or Fisher's exact test. Multiple aneurysms corresponded to 14% of cases. The proportion of women among patients with multiple aneurysms was higher than among those with single aneurysm (64.3% versus 20.9%, P<.01), even if only cases with atherosclerosis were taken into consideration (women among multiple-6/10, 60.0%; among single-14/70, 20.0%; P=.01). Smoking was less reported in cases with multiple (4/14, 28.6%) than with single aneurysm (53/86, 61.6%; P=.04); considering cases with atherosclerosis, such difference decreases (40.0% of multiple versus 68.6% of single, P=.09). although atherosclerosis is present in most cases of both single and multiple aortic aneurysms, male gender and smoking, considered highly influential in such lesions, are less frequent in patients with multiple than in patients with single aneurysms. Thus mechanisms underlying multiple aortic aneurysms are probably different from those related to single, more common aneurysms. Copyright © 2015 Elsevier Inc. All rights reserved.

  14. Assessment of effect of age, gender, and dentoalveolar changes on mandibular morphology: A digital panoramic study

    2018-01-01

    Full Text Available Introduction: With progressive development in the growth and function of the jaws, changes are observed in size as well as shape of the mandible, which vary on the basis of age, gender, and dental status. The objective of this study was to evaluate and assess the morphological changes of the mandible, with varying age, gender, and dental status, using panoramic radiographs. Materials and Methods: A retrospective study was conducted using digital panoramic radiographs taken by Kodak 8000c digital panoramic and cephalometric system on 150 patients, comprising fifty edentulous individuals (above 50 years of age, fifty old dentate individuals (above 50 years of age, and fifty young dentate individuals (below 25 years of age. All the mandibular measurements (gonial angle, ramus length, condylar length (CL, ramus notch depth, and cortical bone thickness were carried out using RadiAnt DICOM VIEWER 2.2.9 (32-bit software. The measurements were then subjected to paired t-test, Tukey's multiple post hoc procedures, and multiple linear regression analysis. Results: Descriptive statistics for all the parameters on the right and left sides of the mandible in both males and females were analyzed. A statistical significance of P < 0.05 was observed for all the variables except one variable (CL. Conclusion: In the present study, all the variables showed increased measurements in males except gonial angle, which was found to be wider in females, indicating that women tend to get affected by varying dental statuses than men. Hence, the parameters used in this study may act as good indicators for the assessment of the effect of age, gender, and dental status on mandibular morphology.

    2013-01-01

    Fourteen perfluoroalkyl substances (PFASs) were measured in serum of the highly endangered captive Chinese alligators, whole body homogenates of six kinds of fish (alligator prey species), and pond water (alligator habitat) in the Anhui Research Center for Chinese Alligator Reproduction. Six PFASs, including PFOS and five perfluorinated carboxylates, were detected in all alligator samples. The most dominant PFAS was PFUnDA, with a mean value of 31.4 ng/mL. Significant positive correlations were observed among the six PFASs, suggesting that they shared similar sources of contamination. Significantly higher PFOS and PFUnDA levels were observed in males, but the other four PFCAs did not differ between genders. An age related PFAS bioaccumulation analysis showed a significant negative correlation of the concentrations for five PFCAs to age, which means that higher concentrations were found in younger animals. Bioaccumulation factors (BAF) in fish for PFASs ranged from 21 to 28,000, with lower BAF for PFOA than that for longer carbon chain PFCAs, including PFUnDA, PFDA, and PFNA. Highlights: •The most dominant PFAS was PFUnDA, followed by PFOS and PFDA in all alligator samples. •Significantly higher PFOS and PFUnDA levels were observed in males. •The concentrations of the five PFCAs showed significant negative correlation to age. -- Age- and gender-related accumulation of perfluoroalkyl substances in captive Chinese alligators

  17. Level of emotional awareness in the general French population: effects of gender, age, and education level.

    Nandrino, Jean-Louis; Baracca, Margaret; Antoine, Pascal; Paget, Virginie; Bydlowski, Sarah; Carton, Solange

    2013-01-01

    The Levels of Emotional Awareness Scale (LEAS) developed by Lane et al. (1990) measures the ability of a subject to discriminate his or her own emotional state and that of others. The scale is based on a cognitive-developmental model in which emotional awareness increases in a similar fashion to intellectual functions. Because studies performed using North American and German populations have demonstrated an effect of age, gender, and level of education on the ability to differentiate emotional states, our study attempts to evaluate whether these factors have the same effects in a general French population. 750 volunteers (506 female, 244 male), who were recruited from three regions of France (Lille, Montpellier, Paris), completed the LEAS. The sample was divided into five age groups and three education levels. The results of the LEAS scores for self and others and the total score showed a difference in the level of emotional awareness for different age groups, by gender and education level. A higher emotional level was observed for younger age groups, suggesting that emotional awareness depends on the cultural context and generational societal teachings. Additionally, the level of emotional awareness was higher in women than in men and lower in individuals with less education. This result might be explained by an educational bias linked to gender and higher education whereby expressive ability is reinforced. In addition, given the high degree of variability in previously observed scores in the French population, we propose a standard based on our French sample.

    The differences in gender- and the age-related changes in triathlon (i.e., swimming, cycling, and running) performances have been previously investigated, but data are missing for duathlon (i.e., running, cycling, and running). We investigated the participation and performance trends and the gender difference and the age-related decline in performance, at the "Powerman Zofingen" long-distance duathlon (10-km run, 150-km cycle, and 30-km run) from 2002 to 2011. During this period, there were 2,236 finishers (272 women and 1,964 men, respectively). Linear regression analyses for the 3 split times, and the total event time, demonstrated that running and cycling times were fairly stable during the last decade for both male and female elite duathletes. The top 10 overall gender differences in times were 16 ± 2, 17 ± 3, 15 ± 3, and 16 ± 5%, for the 10-km run, 150-km cycle, 30-km run and the overall race time, respectively. There was a significant (p triathlons, the age-related decline in the duathlon performance was more pronounced in running than in cycling. Athletes and coaches can use these findings to plan the career in long-distance duathletes with the age of peak performance between 25 and 39 years for both women and men.

    This study aims to explore the association of anthropometric indices of obesity with hypertension in Chinese elderly and its possible gender and age differences. A total of 7070 adults age 60 or older were interviewed in a cross-sectional study conducted in 2017. Anthropometric indices for each participant were measured by using standard methods of trained doctoral/master students. We performed two binary logistic regression models to examine the association of the nine different anthropometric indices and hypertension by gender. Lastly, analyses were performed in two steps stratified for age. Comparing individuals with and without hypertension, there were statistically significant differences in anthropometric indices except height, a body shape index (ABSI), and hip index (HI) in males; and except height in females. There were gender differences in the relationship between anthropometric indices and the prevalence of hypertension in Chinese older adults. After stratification by age, the associations of all anthropometric indices became weaker, disappeared, or even went in the opposite direction. Furthermore, body mass index (BMI) in men (except individuals older than 80) and hip circumference (HC) in women showed a significant impact on the risk of hypertension. The association of anthropometric indices of obesity with hypertension in Chinese elderly differ by gender and age. These findings indicate a need to develop gender-specific strategies for the male and female elderly in the primary and secondary prevention of hypertension.

  20. Gender moderates the associations between attachment and discrete emotions in late middle age and later life.

    Consedine, Nathan S; Fiori, Katherine L

    2009-11-01

    Although patterns of attachment have been linked to patterns of emotional experience, studies in developmentally diverse samples are few and have not yet examined possible gender differences in attachment or their implications for emotional wellbeing. This article describes patterns of attachment in a diverse sample of 616 men and women from middle age and later life, examines the relations between attachment and nine discrete emotions, and tests the thesis that gender moderates these associations. Convenience sampling was used to derive a sample of 616 ethnically diverse men and women from seven ethnic groups. Multiple regressions controlling for demographics found no gender differences in attachment categorizations although men reported greater dimensional fearful avoidance. Security predicted greater joy and interest whereas dismissingness was associated with lower shame and fear and with greater interest. Both preoccupation and fearful avoidance predicted most negative emotions but were not associated with positive emotions. Finally, gender moderated these associations such that (a) attachment security was more closely related to interest and, marginally, joy, among men; (b) fearful avoidance was more closely related to fear and contempt among men; and (c) preoccupation was associated with greater interest among men, whereas fear and contempt were associated with preoccupation among women only. Interpreted in the context of theories of emotions, the social origins of emotional experience, and the different roles that social relationships have for aging men and women, our data imply that attachment styles may differentially predict male emotions because of their less diverse networks.

  1. Gender, Reflexivity, and Positionality in Male Research in One's Own Community With Filipino Seafarers' Wives

    Roderick G. Galam

    2015-07-01

    Full Text Available This article reflects on the epistemological, methodological, and ethical issues related to undertaking a cross-gender research (male researcher with female participants in one's own community. It also examines issues of analysis and representation germane to taking a gendered perspective in this study of the lives and experiences of left-behind women. The article frames the discussion of these issues within four interrelated sites or levels of reflexivity: theoretical reflexivity, gender and fieldwork relations, positionality and the insider/outsider dynamic, and representation. The conclusion reflects on the ethical obligation a researcher conducting a study in one's own community bears and the consequences of this ethical burden on representation.

    Full Text Available Depressive disorders are the most typical disease affecting many different factors of humanity. University students may be at increased risk of depression owing to the pressure and stress they encounter. Therefore, the purpose of this study is comparing the level of depression among male and female athletes and non-athletes undergraduate student of private university in Esfahan, Iran. The participants in this research are composed of 400 male and female athletes as well as no-athletes Iranian undergraduate students. The Beck depression test (BDI was employed to measure the degree of depression. T-test was used to evaluate the distinction between athletes and non-athletes at P≤0.05. The ANOVA was conducted to examine whether there was a relationship between level of depression among non-athletes and athletes. The result showed that the prevalence rate of depression among non-athlete male undergraduate students is significantly higher than that of athlete male students. The results also presented that level of depression among female students is much more frequent compared to males. This can be due to the fatigue and lack of energy that are more frequent among female in comparison to the male students. Physical activity was negatively related to the level of depression by severity among male and female undergraduate students. However, there is no distinct relationship between physical activity and level of depression according to the age of athlete and nonathlete male and female undergraduate students. This study has essential implications for clinical psychology due to the relationship between physical activity and prevalence of depression.

    young control group for both genders. Conclusion: With respect to PCO and AOPP, impaired redox homeostasis is substantially more prominent in males than females. The decrease of G-SH levels in male groups could be attributed to stabilizing the redox status of protein thiol groups by the depletion of the GSH groups. Considering the results, the renal tissue proteins and lipids in different genders may have different susceptibilities to oxidative damage.

    Advanced paternal age (APA) is a reported risk factor for schizophrenia in the offspring. We performed a meta-analysis of this association, considering the effect of gender and study design. We identified articles by searching Pub Med, PsychInfo, ISI, and EMBASE, and the reference lists of identified studies. Previously unpublished data from the Northern Finland 1966 Birth Cohort (NFBC 1966) study were also included. There were 6 cohort studies and 6 case-control studies that met the inclusion criteria. In both study designs, there was a significant increase in risk of schizophrenia in the offspring of older fathers (≥30) compared to a reference paternal age of 25-29, with no gender differences. The relative risk (RR) in the oldest fathers (≥50) was 1.66 [95% confidence interval (95% CI): 1.46-1.89, P APA (≥30) and younger paternal age (<25) increase the risk of schizophrenia; younger paternal age may be associated with an increased risk in males but not females. This risk factor increases the risk of schizophrenia as much as any single candidate gene of risk. The mechanism of these associations is not known and may differ for older and younger fathers.

  5. Population profiling in China by gender and age: implication for HIV incidences.

    Pan, Yuanyi; Wu, Jianhong

    2009-11-18

    With the world's largest population, HIV spread in China has been closely watched and widely studied by its government and the international community. One important factor that might contribute to the epidemic is China's numerous surplus of men, due to its imbalanced sex ratio in newborns. However, the sex ratio in the human population is often assumed to be 1:1 in most studies of sexually transmitted diseases (STDs). Here, a mathematical model is proposed to estimate the population size in each gender and within different stages of reproduction and sexual activities. This population profiling by age and gender will assist in more precise prediction of HIV incidences. The total population is divided into 6 subgroups by gender and age. A deterministic compartmental model is developed to describe birth, death, age and the interactions among different subgroups, with a focus on the preference for newborn boys and its impact for the sex ratios. Data from 2003 to 2007 is used to estimate model parameters, and simulations predict short-term and long-term population profiles. The population of China will go to a descending track around 2030. Despite the possible underestimated number of newborns in the last couple of years, model-based simulations show that there will be about 28 million male individuals in 2055 without female partners during their sexually active stages. The birth rate in China must be increased to keep the population viable. But increasing the birth rate without balancing the sex ratio in newborns is problematic, as this will generate a large number of surplus males. Besides other social, economic and psychological issues, the impact of this surplus of males on STD incidences, including HIV infections, must be dealt with as early as possible.

  7. Thinking about gender types: cognitive organization of female and male types.

    Vonk, Roos; Ashmore, Richard D

    2003-06-01

    We examined the content and dimensional structure of a large and representative sample of gender types. In Study 1, using an open-ended procedure, participants generated 306 different labels for female types (e.g. housewife, feminist, femme fatale, secretary, slob) and 310 for male types (e.g. workaholic, family man, sissy, womanizer, labourer). In Study 2A, a multidimensional configuration of 229 of these male and female types was derived from a free sorting task among a new set of participants. In Study 2B, a subset of types was judged on several dimensions of meaning, which were then fitted into the configuration of types. The most important dimensions in describing the structure of gender types were: young-old, masculine-feminine and traditional-modern. The masculine-feminine dimension showed that the male and female types were largely separated from each other; within each gender category, the types were ordered by their position on the masculine-feminine dimension. Several other aspects of current thinking about men and women are discussed.

    2008-03-01

    Full Text Available Roger D Stanworth, T Hugh JonesCentre of Diabetes and Endocrinology, Barnsley Hospital NHS Foundation Trust, Barnsley, South Yorkshire, United Kingdom; Academic Unit of Diabetes, Endocrinology and Metabolism, University of Sheffield, Sheffield, South Yorkshire, United KingdomAbstract: An international consensus document was recently published and provides guidance on the diagnosis, treatment and monitoring of late-onset hypogonadism (LOH in men. The diagnosis of LOH requires biochemical and clinical components. Controversy in defining the clinical syndrome continues due to the high prevalence of hypogonadal symptoms in the aging male population and the non-specific nature of these symptoms. Further controversy surrounds setting a lower limit of normal testosterone, the limitations of the commonly available total testosterone result in assessing some patients and the unavailability of reliable measures of bioavailable or free testosterone for general clinical use. As with any clinical intervention testosterone treatment should be judged on a balance of risk versus benefit. The traditional benefits of testosterone on sexual function, mood, strength and quality of life remain the primary goals of treatment but possible beneficial effects on other parameters such as bone density, obesity, insulin resistance and angina are emerging and will be reviewed. Potential concerns regarding the effects of testosterone on prostate disease, aggression and polycythaemia will also be addressed. The options available for treatment have increased in recent years with the availability of a number of testosterone preparations which can reliably produce physiological serum concentrations.Keywords: review, testosterone, male, aging

  9. Gender difference of metabolic syndrome and its association with dietary diversity at different ages.

    Tian, Xu; Xu, Xiaohui; Zhang, Kai; Wang, Hui

    2017-09-26

    Previous research indicated that dietary diversity had favorable association with metabolic syndrome (MetS), and it has not been investigated in China. Adults (aged 18+) with complete dietary and biochemical data were collected from 2009 China Health and Nutrition Survey ( n =4308). Dietary diversity was measured by modified Dietary Diversity Score (DDS). MetS was defined by the harmonized criteria. The association between DDS and MetS was investigated by multivariable adjusted logistic regression. An inverse-U shape relationship between MetS risk and age was detected for both genders, and female were more vulnerable than male at old times. More diversified diet decreased the risk of MetS for young female (≥18 & ≤45), similar trends were detected in serum TGs, abdominal adiposity, blood pressure, and fasting blood glucose (all P 60) and male adults (>45&≤60). Greater DDS was associated with higher serum TGs, and lower HDL-C level for male adults, higher blood pressure for old men, but lower blood pressure and fasting blood glucose in young men (all P <0.05). Male adults and old female had the highest risk of getting MetS. More diversified diet decreased MetS risk for young female, but increased the risk for male adults and old female.

    Kristoffersen, S; Lilleng, P K; Mæhle, B O; Morild, I

    2014-05-01

    This retrospective study from Western Norway is based on the cases of 196 homicide victims from 1985 to 2009. The median age of the victims was 35 years, in both genders. Within the cases, 113 of the victims were male and 83 female, 28 victims were under the age of 18, and 19 victims were not native Norwegians. Ethanol was detected in the blood of a higher proportion of male compared to female victims, whereas a higher proportion of female compared to male victims had both illegal/legal drugs detected in their blood. Most perpetrators were male. Men were most often killed by an acquaintance, women by their present or former intimate partner. In 14 cases of intimate partner homicide the perpetrator committed suicide after killing their female partner. The dominant scene of crime was private homes. Most victims were killed by blunt force, sharp force or gunshot. The head was the body region most often injured in the homicide victims. Female victims were more often killed by manual strangulation than male victims. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    1995-01-01

    Investigated the relationships among gender, age, and self-image of adolescents attending three secondary schools in Jamaica. Results revealed statistically significant effects for both gender and age. Gender significantly influenced morals, while age differences affected six other dimensions. Some results contradicted past research. (RJM)

  12. Impact of Type of Sport, Gender and Age on Red Blood Cell Deformability of Elite Athletes.

    Tomschi, Fabian; Bloch, Wilhelm; Grau, Marijke

    2018-01-01

    Our objective was to detect possible differences in red blood cell (RBC) deformability of elite athletes performing different types of sports and being of different age and gender.182 athletes were included in this cross-sectional study. RBC deformability was measured using the laser-assisted optical rotational cell-analyzer. Maximal elongation index (EI  max ) and shear stress at half-maximum deformation (SS  1/2 ) were calculated. The ratio SS  1/2  /EI  max  (EI  Ratio ) was calculated with low values representing high RBC deformation. Hematocrit (Hct) and mean cellular volume (MCV) were determined in venous blood. Overall RBC deformability did not differ between male and female athletes but, when separated by age of the subjects, RBC deformability increased with age in male but not in female athletes. RBC deformability was lower in Combat sports compared other sport groups. Hct was higher in male compared to female athletes while no difference was observed for MCV. MCV and Hct increased with increasing age. A negative correlation was found between the EI  Ratio  and MCV and between EI  Ratio  and Hct. RBC deformability is influenced by age and endurance rate of the sport which suggests that the RBC system may adapt to changing conditions such as adolescence with the onset effects of sex hormones or physical exercise. © Georg Thieme Verlag KG Stuttgart · New York.

  13. Gender-dependent effects of aging on the kidney

    A.L. Gava

    2011-09-01

    Full Text Available It is well known that the kidney plays an important role in the development of cardiovascular diseases such as hypertension. The normal aging process leads to changes in kidney morphology, hemodynamics and function, which increase the incidence of cardiovascular events in the elderly population. These disturbances are influenced by several factors, including gender. In general, females are protected by the effects of estrogens on the cardiorenal system. Several studies have demonstrated the beneficial effects of estrogens on renal function in the elderly; however, the relationships between androgens and kidney health during one’s lifetime are not well understood. Sex steroids have many complex actions, and the decline in their levels during aging clearly influences kidney function, decreases the renal reserve and facilitates the development of cardiovascular disorders. Therefore, in this review, we discuss the cellular, biochemical, and molecular mechanisms by which sex hormones may influence renal function during the aging process.

  14. Interdependent mechanisms for processing gender and emotion:The special status of angry male faces

    Daniel A Harris

    2016-07-01

    Full Text Available While some models of how various attributes of a face are processed have posited that face features, invariant physical cues such as gender or ethnicity as well as variant social cues such as emotion, may be processed independently (e.g., Bruce & Young, 1986, other models suggest a more distributed representation and interdependent processing (e.g., Haxby, Hoffman, & Gobbini, 2000. Here we use a contingent adaptation paradigm to investigate if mechanisms for processing the gender and emotion of a face are interdependent and symmetric across the happy-angry emotional continuum and regardless of the gender of the face. We simultaneously adapted participants to angry female faces and happy male faces (Experiment 1 or to happy female faces and angry male faces (Experiment 2. In Experiment 1 we found evidence for contingent adaptation, with simultaneous aftereffects in opposite directions: male faces were biased towards angry while female faces were biased towards happy. Interestingly, in the complementary Experiment 2 we did not find evidence for contingent adaptation, with both male and female faces biased towards angry. Our results highlight that evidence for contingent adaptation and the underlying interdependent face processing mechanisms that would allow for contingent adaptation may only be evident for certain combinations of face features. Such limits may be especially important in the case of social cues given how maladaptive it may be to stop responding to threatening information, with male angry faces considered to be the most threatening. The underlying neuronal mechanisms that could account for such asymmetric effects in contingent adaptation remain to be elucidated.

  16. Substance use across adolescence: do gender and age matter?

    Celeste Simões

    2014-03-01

    Full Text Available Many of the choices which impact in lifetime health, such as substance use, are made in adolescence. It becomes, therefore, important to know the factors associated to these behaviours in adolescence in different contexts of life. To analyze these factors, an explanatory model was developed using structural equation modeling. Data from 12.881 state school students from Portugal who participated in two waves of the Health Behaviours in School-aged Children (HBSC / World Health Organization (WHO survey were analyzed. The model fits well the data [CFI: .985; NNFI: .980; RMSEA: .018 (.017-.020; SRMR: .018]. For each of the dependent factors, the levels of variance ranged from 12% (tobacco use to 47% (alcohol and illicit drugs use. Alcohol and tobacco present the strongest associations to illicit drugs use. Relationships with family, friends, classmates, and teachers were also associated with substance use, being this association mediated by certain factors, including psychological symptoms, well-being, and school satisfaction. Several non-invariant paths were obtained in gender and age comparisons. The results showed that substance use is associated with several factors and that social factors are mediated by personal factors. Results have also shown that gender and age are important factors on substance use.

  17. Feedback processing in adolescence: an event-related potential study of age and gender differences.

    Grose-Fifer, Jillian; Migliaccio, Renee; Zottoli, Tina M

    2014-01-01

    Adolescence has frequently been characterized as a period of increased risk taking, which may be largely driven by maturational changes in neural areas that process incentives. To investigate age- and gender-related differences in reward processing, we recorded event-related potentials (ERPs) from 80 participants in a gambling game, in which monetary wins and losses were either large or small. We measured two ERP components: the feedback-related negativity (FRN) and the feedback P3 (fP3). The FRN was sensitive to the size of a win in both adult (aged 23-35 years) and adolescent (aged 13-17 years) males, but not in females. Small wins appeared to be less rewarding for males than for females, which may in part explain more approach-driven behavior in males in general. Furthermore, adolescent boys showed both delayed FRNs to high losses and less differentiation in FRN amplitude between wins and losses in comparison to girls. The fP3, which is thought to index the salience of the feedback at a more conscious level than the FRN, was also larger in boys than in girls. Taken together, these results imply that higher levels of risk taking that are commonly reported in adolescent males may be driven both by hypersensitivity to high rewards and insensitivity to punishment or losses. © 2014 S.

  18. Gender-Associated Genomic Differences in Colorectal Cancer: Clinical Insight from Feminization of Male Cancer Cells

    Rola H. Ali

    2014-09-01

    Full Text Available Gender-related differences in colorectal cancer (CRC are not fully understood. Recent studies have shown that CRC arising in females are significantly associated with CpG island methylator phenotype (CIMP-high. Using array comparative genomic hybridization, we analyzed a cohort of 116 CRCs (57 males, 59 females for chromosomal copy number aberrations (CNA and found that CRC in females had significantly higher numbers of gains involving chromosome arms 1q21.2–q21.3, 4q13.2, 6p21.1 and 16p11.2 and copy number losses of chromosome arm 11q25 compared to males. Interestingly, a subset of male CRCs (46% exhibited a "feminization" phenomenon in the form of gains of X chromosomes (or an arm of X and/or losses of the Y chromosome. Feminization of cancer cells was significantly associated with microsatellite-stable CRCs (p-value 0.003 and wild-type BRAF gene status (p-value 0.009. No significant association with other clinicopathological parameters was identified including disease-free survival. In summary, our data show that some CNAs in CRC may be gender specific and that male cancers characterized by feminization may constitute a specific subset of CRCs that warrants further investigation.

  19. Gender roles and social policy in an ageing society: the case of Japan

    Meiko Makita

    2010-10-01

    Full Text Available This article reviews the major underpinnings of the Japanese welfare state in the context of social care from a feminist perspective. In Japan, familycare responsibilities have traditionally been assigned to women; hence, care has long been a women’s issue. However, as the social contract of a male breadwinner and a “professional housewife” gradually fades out, Japanese women find more opportunities to renegotiate their caring roles. Of course, this social transformation did not occur in isolation, it was influenced by patterns in economic development, state policies and mainly demographic changes. All this has stimulated new state responses in the form of social welfare expansion that arguably aim to relieve women of the burdens of family-care. The issue remains, however, as to whether Japan would be able to recognise that the main structural issues of population ageing do not originate from demographic changes, but from a strict gendered division of labour and gender inequality.

    Full Text Available The aim of this study is to verify the current anthropometrical status of the pupils of the age 12, as well as to compare it with the standards of raising in accordance with the WHO standards. In the study were included 62 pupils (42 male and 20 female. The anthropometric tests were done in height, weight, biacromial and elbow breadth, subcutaneous adipose tissue at the : suprailiac skinfold; subscapular skinfold; triceps skinfold, as well as the abdominal circumference. The results showed that there was a heterogenic distribution of results, especially in the body weight, where the distribution between the minimal and maximal results is 28-70 kg, with the average 43, 14 ± 9, 78 of standard deviation with the male pupils, while with the female pupils was noticed more homogenous group and the standard deviation was significantly lower than with the female pupils in all variables. The findings show that almost in all measured variables female pupils are more developed at this age, especially the body high, body weight and subcutaneous adipose tissue, while as regards the abdominal circumference and body breadth, the male pupils are more developed. Comparison of symbolic sample of this research with the WHO data shows an approximate trend of raising and development of children which were included in this research, and the difference is as follows: Female pupils age 12, body height=151.97 cm

    2013-12-01

    Functional inhibitory neural networks mature progressively with age. However, nothing is known about the impact of gender on their development. This study employed functional magnetic resonance imaging (fMRI) to investigate the effects of age, sex, and sex by age interactions on the brain activation of 63 healthy males and females, between 13 and 38 years, performing a Stop task. Increasing age was associated with progressively increased activation in typical response inhibition areas of right inferior and dorsolateral prefrontal and temporo-parietal regions. Females showed significantly enhanced activation in left inferior and superior frontal and striatal regions relative to males, while males showed increased activation relative to females in right inferior and superior parietal areas. Importantly, left frontal and striatal areas that showed increased activation in females, also showed significantly increased functional maturation in females relative to males, while the right inferior parietal activation that was increased in males showed significantly increased functional maturation relative to females. The findings demonstrate for the first time that sex-dimorphic activation patterns of enhanced left fronto-striatal activation in females and enhanced right parietal activation in males during motor inhibition appear to be the result of underlying gender differences in the functional maturation of these brain regions. © 2013.

  2. The effects of age, gender, and crash types on drivers' injury-related health care costs.

    Shen, Sijun; Neyens, David M

    2015-04-01

    There are many studies that evaluate the effects of age, gender, and crash types on crash related injury severity. However, few studies investigate the effects of those crash factors on the crash related health care costs for drivers that are transported to hospital. The purpose of this study is to examine the relationships between drivers' age, gender, and the crash types, as well as other crash characteristics (e.g., not wearing a seatbelt, weather condition, and fatigued driving), on the crash related health care costs. The South Carolina Crash Outcome Data Evaluation System (SC CODES) from 2005 to 2007 was used to construct six separate hierarchical linear regression models based on drivers' age and gender. The results suggest that older drivers have higher health care costs than younger drivers and male drivers tend to have higher health care costs than female drivers in the same age group. Overall, single vehicle crashes had the highest health care costs for all drivers. For males older than 64-years old sideswipe crashes are as costly as single vehicle crashes. In general, not wearing a seatbelt, airbag deployment, and speeding were found to be associated with higher health care costs. Distraction-related crashes are more likely to be associated with lower health care costs in most cases. Furthermore this study highlights the value of considering drivers in subgroups, as some factors have different effects on health care costs in different driver groups. Developing an understanding of longer term outcomes of crashes and their characteristics can lead to improvements in vehicle technology, educational materials, and interventions to reduce crash-related health care costs.

  3. Male perpetration of teen dating violence: associations with neighborhood violence involvement, gender attitudes, and perceived peer and neighborhood norms.

    Reed, Elizabeth; Silverman, Jay G; Raj, Anita; Decker, Michele R; Miller, Elizabeth

    2011-04-01

    This study aims to examine the link between male perpetration of teen dating violence (TDV) and neighborhood violence, as well as associations with gender attitudes and perceived peer and neighborhood norms related to violence among a sample of urban adolescent boys. Participants of this cross-sectional study (N = 275) were between the ages of 14 and 20 years and recruited from urban community health centers. Crude and adjusted logistic and linear regression models were used to examine TDV perpetration in relation to (a) neighborhood violence involvement, (b) perceptions of peer violence, (c) perceptions of neighborhood violence, and (d) gender attitudes. Slightly more than one in four (28%) boys reported at least one form of TDV perpetration; among boys who have ever had sex, almost half (45%) reported at least one form of TDV perpetration. In logistic and linear regression models adjusted for demographics, boys who reported TDV perpetration were more likely to report involvement in neighborhood violence (odds ratio (OR) = 3.1; 95% confidence interval (CI) = 1.7-5.5), beliefs that their friends have perpetrated TDV (OR = 2.7; 95%CI = 1.4-5.1), perceptions of violent activity within their neighborhood (OR = 3.0; 95%CI = 1.4-6.3), and greater support of traditional gender norms (β = 3.2, p = 0.002). The findings suggest that efforts are needed to address boys' behaviors related to the perpetration of multiple forms of violence and require explicit efforts to reduce perceived norms of violence perpetration as well as problematic gender attitudes (e.g., increasing support for gender equity) across boys' life contexts.

    1998-12-01

    The present study is a detailed evaluation of age at smoking initiation among university male students in Kuwait based on a random sample of 664 students selected from all students during 1993. The Acturial Life Table analysis revealed that almost one tenth of the students initiated cigarette smoking between ages 16 and 17 with the rate of initiation increasing rapidly thereafter and reaching 30% by age 20 and almost 50% by the time they celebrate their 24th birthday. The most important environmental risk factor positively associated for smoking initiation was observed to be the history of smoking among siblings with a relative risk of 1.4. Compared to students of medicine and engineering, the students of other faculties revealed a higher risk in smoking initiation with an RR = 1.77 for sciences and commerce and 1.61 for other faculties (arts, law, education and Islamic studies). The analysis revealed a rising generation trend in cigarette smoking. There is a need for reduction of this trend among young adults in Kuwait and throughout other countries in the region.

    Male hypogonadism is common in the elderly and has been associated with increased risk of mortality. Our objective has been to assess the prevalence of primary and central hypogonadism in elderly male patients admitted to the hospital because of acute illness. We also evaluated the relationships between gonadal dysfunction and in-hospital mortality. 150 patients, aged ≥65 years, admitted during 2010 and 2011 in our geriatric unit, were studied. Serum concentrations total, bioavailable and free testosterone, as well as of follicle-stimulating hormone and luteinizing hormone were quantified in every patient. Hypogonadism was defined by the presence of serum testosterone levels lower than 200 ng/dl. Hypogonadism was found in 80 patients (53.3 %). Serum gonadotropin concentrations were elevated in 43.7 % of these patients, whereas 41.3 % of hypogonadic patients showed normal and 15 % low gonadotropin concentrations. Respiratory tract infection and congestive heart failure were the main causes of hospitalization in hypogonadal men, whereas acute cerebrovascular disease was the main reason for admission in eugonadal patients. Of the 13 patients who died during hospitalization, 12 were hypogonadic. Patients who died showed significantly lower serum levels of total, free and bioavailable testosterone than those found in patients who survived. Our results show that about half of patients admitted for acute illness have hypogonadism, mainly of non-hypergonadotropic type. Gonadal hypofunction is significantly related with in-hospital mortality. A low value of serum testosterone may be a predictor for mortality in elderly male patients.

  6. Pedestrians' vulnerability in floodwaters: sensitivity to gender and age

    Arrighi, Chiara; Castelli, Fabio

    2017-04-01

    Among the causes of fatalities during floods, the loss of stability is an aspect which has been usually investigated with conceptual models and laboratory experiments. The human body geometry has been often simplified to derive mechanical equilibrium conditions for toppling and sliding due to weight and hydrodynamic actions. Experimental activity produced water depth versus velocity diagrams showing the critical conditions for people partly immersed in floodwaters, whose scatter reflects the large variability of tested subjects (i.e. children, men and women with different physical characteristics). Nevertheless, the proposed hazard criteria based on the product number HV are not capable of distinguishing between different subjects. A dimensionless approach with a limited number of parameters and 3D numerical simulations highlight the significance of subject height and quantify the drag forces different subjects are able to withstand. From the mechanical point of view, this approach significantly reduces the experimental scatter. Differences in subjects' height are already an evidence of gender differences; however, many other parameters such as age and skeletal muscle mass may play a significant role in individual responses to floodwater actions, which can be responsible of the residual unexplained variance. In this work, a sensitivity analysis of critical instability conditions with respect to gender/age-related parameters is carried out and results and implications for flood risk management are discussed.

  7. Effect of age, gender and body mass index on visual and auditory reaction times in Indian population.

    Nikam, Lalita H; Gadkari, Jayshree V

    2012-01-01

    The effect of Age. Gender and Body Mass Index (BMI) on the Visual (VRT) and Auditory reaction time (ART) was studied in 30 males and 30 females in the age group of 18-20 years along with 30 males and 30 females in the age group of 65-75 years. Statistical analysis of the data by one-way ANOVA and post-hoc by Tukey-HSD test showed that BMI, VRT and ART were significantly higher in old than young individuals. Females had higher BMI and longer reaction times than males. There was significant positive correlation between BMI and reaction times (VRT and ART) in both males and females by Pearson correlation analysis. Older individuals should be more careful and vigilant about the injuries and falls due to increased reaction time. Longer reaction times and higher BMI in females could be attributed to fluid and salt retention due to female sex hormones affecting sensorimotor co-ordination.

  8. Gender, mature appearance, alcohol use, and dating as correlates of sexual partner accumulation from ages 16-26 years.

    Zimmer-Gembeck, Melanie J; Collins, W Andrew

    2008-06-01

    To determine growth in sexual partnering from age 16-26 years, and to test whether biological and social factors launched these growth patterns. A prospective design was used. Participants were 176 young people (47% female) followed from birth to age 26 years. Sexual partnering was measured as the accumulated number of different sexual intercourse partners at ages 16, 19, 23, and 26 years. Physical appearance of maturity, alcohol use, and dating were measured at ages 13-16 via observations, interviews, and questionnaires. Mature appearance at age 13 years, use of alcohol more than monthly at age 16, and a history of a steady romantic partner before age 16 were each associated with a greater number of sexual intercourse partners by age 16. However a more mature appearance, more frequent alcohol use, and greater dating involvement did not foreshadow a steeper accumulation of sexual partners between ages 16 and 26. Only gender had such a "growth" influence, with males accruing sexual partners more rapidly from the ages of 16-26 years when compared with females. Adolescents had accumulated a higher number of sexual partners by age 16 years when they looked older, drank alcohol more frequently, and were more involved with dating in early to middle adolescence. Also male gender was associated with accumulation of sexual partners more rapidly between ages 16 and 26 years, and there was little indication that the accumulation of different sexual partners had begun to slow by age 26 for the average participant.

    Full Text Available Studies have shown an inverse relationship between physical activity level (PAL, quality of life (QoL and use of medications in the elderly. The objective of this study was to analyze possible relationships and differences between PAL, QoL and use of medications in the elderly. A total of 192 subjects (≥ 60 years were selected by stratified random sampling according to census sector. The following assessment instruments were used: a Modified Baecke Questionnaire for older adults, b Medical Outcomes Study – 36-Item Short Form Health Survey, and c Sociodemographic and Health Factors Questionnaire. Descriptive statistics and parametric and nonparametric tests were used (p < 0.05. a With respect to chronological age, significant differences between groups were only observed for PAL, with G1 (60-69 years being more active than the other groups. b With respect to gender irrespective of age, analysis showed a difference in QoL and in the number of medications, with men reporting better perceived QoL and using fewer medications. c With respect to gender but considering chronological age, differences in PAL, QoL and medication use were observed between genders for specific age groups. In conclusion, in the elderly a PAL is low, declines even more during advanced age and is higher in men than in women during the first decade of old age, and b men report better perceived QoL and use fewer medications than women.

  10. Prejudice at the nexus of race and gender: an outgroup male target hypothesis.

    Navarrete, Carlos David; McDonald, Melissa M; Molina, Ludwin E; Sidanius, Jim

    2010-06-01

    Adopting an evolutionary approach to the psychology of race bias, we posit that intergroup conflict perpetrated by male aggressors throughout human evolutionary history has shaped the psychology of modern forms of intergroup bias and that this psychology reflects the unique adaptive problems that differ between men and women in coping with male aggressors from groups other than one's own. Here we report results across 4 studies consistent with this perspective, showing that race bias is moderated by gender differences in traits relevant to threat responses that differ in their adaptive utility between the sexes-namely, aggression and dominance motives for men and fear of sexual coercion for women. These results are consistent with the notion that the psychology of intergroup bias is generated by different psychological systems for men and women, and the results underscore the importance of considering the gender of the outgroup target as well as the gender of the agent in psychological studies on prejudice and discrimination.

    2009-01-01

    Full Text Available Purpose: To determine the impact of age and gender on the clinicopathological characteristics of histologically confirmed bladder cancer in India. Materials and Methods: From January 2001 to June 2008, records of patients with bladder cancer were evaluated for age and gender at presentation, clinical symptoms, cystoscopic finding, history of smoking, and histopathological characteristics. A total of 561 patients were identified from the computer-based hospital information system and the case files of patients. Results: A total of 97% of the patients presented with painless hematuria. The mean age was 60.2 ± 4.4 years old (range: 18-90 years old and the male to female ratio was 8.6:1. Transitional cell carcinoma (TCC was the most common histological variety, which was present in 97.71% (470 of 481 of the patients. A total of 26% of the patients had muscle invasive disease at the time of presentation. However, 34.5% (166 of 481 of the patients did not show any evidence of detrusor muscle in their biopsy specimen. In patients with nonmuscle-invasive bladder carcinoma, 55% had p Ta while 45% had p T1. Overall, 44.7% (215 of 481 of the patients had low-grade disease. Among patients younger than 60 years old, low-grade (51.0% vs. 38.1%; P = 0.006 and low-stage (77.1% vs. 70.8%; P = 0.119 disease were more prevalent than in patients older than 60 years old. The incidence of smoking was much higher among males compared with females (74% vs. 22%. Conclusion: TCC is the predominant cancer, with significant male preponderance among Indian patients. Younger-aged patients have low-grade disease. Hematuria is the most common presentation and greater awareness is needed not to overlook bladder cancer.

    2016-01-01

    BACKGROUND AND AIMS: The influence of gender and age on risk factor prediction of coronary artery calcification (CAC) in symptomatic patients is unclear. METHODS: From the European Calcific Coronary Artery Disease (EURO-CCAD) cohort, we retrospectively investigated 6309 symptomatic patients, 62......, diabetes and smoking were independently predictive of CAC presence in both genders. In addition to a progressive increase in CAC with age, the most important predictors of CAC presence were dyslipidaemia and diabetes (β = 0.64 and 0.63, respectively) in males and diabetes (β = 1.08) followed by smoking (β...... = 0.68) in females; these same risk factors were also important in predicting increasing CAC scores. There was no difference in the predictive ability of diabetes, hypertension and dyslipidaemia in either gender for CAC presence in patients aged 70, only...

  13. Results from a new mathematical model of gastrointestinal transit that incorporates age and gender-dependent physiological parameters

    Stubbs, J.B.

    1992-01-01

    Recently published data on effects of age and gender-dependent GI physiology and motility have been used to develop a new mathematical model describing the transit and adsorption of substances through the GI tract. This mathematical description of GI tract kinetics utilises more physiologically accurate transit processes than the ICRP Report 30 GI model. The model uses a combination of zero and first-order kinetics to describe motility. Some of the physiological parameters that the new model uses are gender, age, phase of the menstrual cycle, meal composition and gastric phase (solid versus liquid). A computer algorithm based on this model has been derived and results for young males are compared to those of the ICRP 30 model. Comparison of gastrointestinal residence times for 99 Tc m and 111 In labelled compounds, as a function of gender and age, are also presented. (author)

    Taylor, Laramie D; Setters, Tiffany

    2011-07-01

    The impact of exposure to media representations of aggressive, attractive, female protagonists on audiences' gender role expectations for women was explored through a laboratory experiment with 122 undergraduates from a large university on the west coast of the United States. Participants viewed a segment of a major Hollywood motion picture that featured a female protagonist who was either highly attractive or less attractive and either highly aggressive or not aggressive. Viewing clips featuring a female protagonist who was both aggressive and stereotypically attractive led to greater endorsement of stereotypically feminine and stereotypically masculine gender role expectations for women. The effect on endorsement of stereotypically masculine expectations was partially mediated by the perception that the protagonist was a good role model for women. Although women endorsed both feminine and masculine gender role expectations for women more strongly than men, the effects of exposure to aggressive, attractive, female protagonists were similar for both male and female participants. Results are discussed in terms of gender stereotype activation and superwoman expectations for women.

  18. Age and Gender Differences in the Relation between Self-Concept Facets and Self-Esteem

    Arens, A. Katrin; Hasselhorn, Marcus

    2014-01-01

    This study tested whether the gender intensification hypothesis applies to relations between multiple domain-specific self-concept facets and self-esteem. This hypothesis predicts gender-stereotypic differences in these relations and assumes they intensify with age. Furthermore, knowledge about gender-related or age-related differences in…

    Brain lateralization is a widely studied topic, however there has been little work focused on lateralization of intrinsic networks (regions showing similar patterns of covariation among voxels) in the resting brain. In this study, we evaluate resting state network lateralization in an age and gender-balanced functional magnetic resonance imaging (fMRI) dataset comprising over 600 healthy subjects ranging in age from 12 to 71. After establishing sample-wide network lateralization properties, we continue with an investigation of age and gender effects on network lateralization. All data was gathered on the same scanner and preprocessed using an automated pipeline (Scott et al., 2011). Networks were extracted via group independent component analysis (gICA) (Calhoun, Adali, Pearlson, & Pekar, 2001). Twenty-eight resting state networks discussed in previous (Allen et al., 2011) work were re-analyzed with a focus on lateralization. We calculated homotopic voxelwise measures of laterality in addition to a global lateralization measure, called the laterality cofactor, for each network. As expected, many of the intrinsic brain networks were lateralized. For example, the visual network was strongly right lateralized, auditory network and default mode networks were mostly left lateralized. Attentional and frontal networks included nodes that were left lateralized and other nodes that were right lateralized. Age was strongly related to lateralization in multiple regions including sensorimotor network regions precentral gyrus, postcentral gyrus and supramarginal gyrus; and visual network regions lingual gyrus; attentional network regions inferior parietal lobule, superior parietal lobule and middle temporal gyrus; and frontal network regions including the inferior frontal gyrus. Gender showed significant effects mainly in two regions, including visual and frontal networks. For example, the inferior frontal gyrus was more right lateralized in males. Significant effects of age

  1. Digital Games, Gender and Learning in Engineering: Do Females Benefit as Much as Males?

    Joiner, Richard; Iacovides, Jo; Owen, Martin; Gavin, Carl; Clibbery, Stephen; Darling, Jos; Drew, Ben

    2011-04-01

    The aim of this paper was to explore whether there is a gender difference in the beneficial effects of Racing Academy, which is a video game used to support undergraduate students learning of Mechanical Engineering. One hundred and thirty-eight undergraduate students (15 females and 123 males) participated in the study. The students completed a pre-test a week before they started using Racing Academy. The pre-test consisted of a test of students' knowledge of engineering, and a measure of students' motivation towards studying engineering. A week after using Racing Academy the students completed a post-test which was identical to the pre-test, except it also included a measure of how frequently they used Racing Academy and how motivating the students found playing Racing Academy. We found that after playing Racing Academy the students learnt more about engineering and there was no gender difference in the beneficial effect of Racing Academy, however there is some evidence that, female students found Racing Academy more motivating than male students. The implications for the use and design of video games for supporting learning for both males and females are discussed.

  2. Preschool Gender-Typed Play Behavior at Age 3.5 Years Predicts Physical Aggression at Age 13 Years.

    2018-05-01

    Gender differences in play behavior and physical aggression have been consistently reported. Theoretical perspectives concerning evolutionary, social, and social-cognitive mechanisms suggest that male-typical play behavior during childhood increases subsequent physical aggression. The evidence supporting these connections is limited, however. The present study investigated the association between gender-typed play behavior in early childhood and physical aggression in early adolescence using a sample drawn from a longitudinal, population study, the Avon Longitudinal Study of Parents and Children. Based on gender-typed play behavior as measured by the Pre-School Activities Inventory at age 3.5 years, samples of masculine (64 boys, 60 girls), feminine (80 boys, 66 girls), and randomly selected control children (55 boys, 67 girls) were recruited at age 13 years and administered the Reinisch Aggression Inventory. After controlling for a range of sociodemographic variables, maternal characteristics, and behavioral problems, including hyperactivity and conduct problems at age 3.5, significant group differences in physical aggression at age 13 were found among children classified as masculine, control, and feminine at age 3.5. Masculine children exhibited significantly more physical aggression than control children or feminine children, and control children exhibited significantly more physical aggression than feminine children. The association between gender-typed play behavior and physical aggression was not moderated by sex. These results suggest that the degree of childhood gender-typed play behavior independently predicts the degree of physical aggression at adolescence in boys and in girls.

    2012-11-01

    Full Text Available The birth in different quarters of the year involved differences regarding maturational development in handball players, which may influence the selection, development and consolidation in the elite in handball. This study sought to investigate the relative age effect in elite male handball players in Spain. To do this, data of birth and specific position of 586 players were analyzed, who participe in the League ASOBAL in seasons between 2003-04 and 2008-09. Comparisons and differences were studied by 2 tests and Z.Analysis of results revealed a higher percentage of players born in the first quarter, significant differences were confirmed in spanish players. Specifically, the highest percentages of players born in the first months of the year were the specific positions of the first offensive line and the goalkeeper.In conclusion, the results seem to confirm a relative effect of age on the players analyzed. The nationality and specific positions have a significant relationship with this.Keys words:  RAE, professional, birth date, detection, selection, talent.

  4. Male-female discrimination: an analysis of gender gap and its determinants

    Claudio Quintano

    2013-05-01

    Full Text Available In recent years, the occupational dynamics have brought in significant innovations in Italy, as the increased participation of women in the labour market, that have stimulated studies about the gender wage gap, concerning the different remuneration reserved to male and female workers. In this work the Authors, following Oaxaca and Blinder approach, estimate the gap for Italian employers and proceed to its decomposition, one part due to differences in individual characteristics (endowment effect and another part due to the different returns on the same characteristics (coefficient effect, related to discrimination. Then, the gender wage gap and its decomposition is analyzed with reference to Italian macro-areas considered separately with the aim to highlight the different fundamental dynamics. The model has also been modified using the Heckmann correction to eliminate the bias due to self-selection; i.e. the different propensity to work for men and women.

    2017-08-01

    Cognitive reserve (CR) and brain reserve (BR) are protective factors against age-associated cognitive decline and neurodegenerative disorders. Very limited evidence exists about gender effects on brain aging and on the effect of CR on brain modulation in healthy aging and Alzheimer's Dementia (AD). We investigated gender differences in brain metabolic activity and resting-state network connectivity, as measured by 18 F-FDG-PET, in healthy aging and AD, also considering the effects of education and occupation. The clinical and imaging data were retrieved from large datasets of healthy elderly subjects (HE) (225) and AD patients (282). In HE, males showed more extended age-related reduction of brain metabolism than females in frontal medial cortex. We also found differences in brain modulation as metabolic increases induced by education and occupation, namely in posterior associative cortices in HE males and in the anterior limbic-affective and executive networks in HE females. In AD patients, the correlations between education and occupation levels and brain hypometabolism showed gender differences, namely a posterior temporo-parietal association in males and a frontal and limbic association in females, indicating the involvement of different networks. Finally, the metabolic connectivity in both HE and AD aligned with these results, suggesting greater efficiency in the posterior default mode network for males, and in the anterior frontal executive network for females. The basis of these brain gender differences in both aging and AD, obtained exploring cerebral metabolism, metabolic connectivity and the effects of education and occupation, is likely at the intersection between biological and sociodemographic factors.

    2008-11-01

    Quality of life (QoL) is impaired in children with atopic dermatitis (AD) but the various aspects of QoL may not be equally affected. Aim. To evaluate if age and gender affect some aspects of QoL in children with AD. The Children's Dermatology Life Quality Index (CDLQI) was used for all children with AD seen at a paediatric dermatology clinic over a 3-year period. Disease severity was assessed using the SCORing Atopic Dermatitis (SCORAD) and Nottingham Eczema Severity Score (NESS) tools. We reviewed CDLQI in 133 children (70 male and 63 female; age range 5-16 years) with AD. Itch, sleep disturbance, treatment and swimming/sports were the four aspects of QoL issues that were most commonly affected, in 50%, 47%, 38% and 29% of patients, respectively. Problems with interpersonal issues (friendship, school/holidays, and teasing/bullying) occurred in only a minority of children (genders similarly but were generally more common in children gender are relevant factors in QoL, with the issue of clothes/shoes being more troublesome for girls. itch and sleep disturbance seem to be a problem mainly in younger children.

    We examined gender differences in mortality, morbidity, and the association between the 2. We used health data from 2 studies of middle-aged men and women: the British Whitehall II cohort of employees from 20 civil service departments in London and the 1989 French GAZEL (this acronym refers to the French gas and electric companies) of employees of France's national gas and electricity company. Participants were aged 35 to 55 years when assessed for morbidity and followed up for mortality over 17 years. Male mortality was higher than female mortality in Whitehall II (hazard ratio [HR] = 1.56; 95% confidence interval [CI] = 1.28, 1.91) and the GAZEL cohort (HR = 1.99; CI = 1.66, 2.40). Female excess morbidity was observed for some measures in the Whitehall II data and for 1 measure in the GAZEL data. Only self-reported sickness absence in the Whitehall II data was more strongly associated with mortality among men (P = .01). Mortality was lower among women than among men, but morbidity was not consistently higher. The lack of gender differences in the association between morbidity and mortality suggests that this is not a likely explanation for the gender paradox, which refers to higher morbidity but lower mortality among women than among men.

    2011-10-01

    Full Text Available The Professional Executive Secretary has been occupying space increasingly evident in the labor market and organizational structure, both because of market demand, the needs of dynamism in the modern administration that demonstrates the growth of the reference to it. It has sought in his field vision and attitude of performance excellence with fulfilling its role with its own characteristics. This study aims to investigate the general challenges for the Executive Secretariat professional male in contemporary organizations. We defined the following objectives: to analyze the insertion of the male in the profession of Executive Secretary and identify the challenges faced by the Executive Secretary of the males to their development and professional growth. To this end, we performed a literature search, followed by a field survey. It is a qualitative research because data collected, and then make a qualitative analysis of results from selected literature. The survey was conducted in organizations from the public and private, state of Ceará. The sample was represented by professional male graduates in the executive secretariat at the Federal University of Ceará and working in the area. After analyzing the data it was concluded that despite the obstacles to be overcome, the tendency is that these opportunities work for the professional male grow, requiring that all actors in the field to seek gender equity in the profession.

    McCarthy, John; Holliday, Ebony L.

    2004-01-01

    A traditional male gender role reflects an affirmation of masculine identity associated with such qualities as success and self-reliance. This gender role is examined from a diversity perspective in counseling, because it may affect many men's help-seeking attitudes and behaviors. Suggestions from the literature are reviewed from the standpoint of…

    Using individual-level data for China, Korea, and Japan for 2006, this research examines how the age of children influences life satisfaction for males and females in East Asian countries. Our results show that the life satisfaction of males is barely affected by a child of the relationship, whereas the life satisfaction of females with a young child is lower than that of females who do not have a child. This result holds for countries at different development stages. There is also a gender d...

  12. Blessed art thou among women: male nursing students and gender inequalities in Chile.

    Ayala, Ricardo A; Holmqvist, Moira T; Messing, Helga B; Browne, Rodrigo F

    2014-12-01

    The evolution of nursing education into an academic curriculum and the growing interest of men in nursing have been significant landmarks in the development of a 'female' occupation. Chilean nursing is considered as the leading example of nursing education in Latin America, demanding a five-year training on a full-time university programme. The consequences of education, however, are assumed as more egalitarian opportunities, disregarding the latent replication of structures that perpetuate inequalities. To comprehend the socialisation of male nursing students and its relation with their masculine identity and the construction of inequalities in nursing education. We draw upon interviews undertaken with beginner and advanced nursing students from a Chilean university. Approval was obtained from the relevant Ethics Committee. The data were organised to allow the development of concepts by using the Grounded Theory approach. The analysis uncovers paradoxical results of nursing education and its ineffectiveness in preventing gender-based inequalities. The interest in empowering nursing politically may lead to favour an increasing number of men entering nursing in ways that facilitate male students' progress. Furthermore, there exist discourses of compassion that feed consideration for male students, engendering in the process the prospect of professional success and the gravitation into strategic positions in the employment market. These are mechanisms that reproduce earlier gender-based inequalities in nursing. In the light of the social reproduction theory, the academisation of Chilean nursing seems to be built upon historical gender asymmetries. Although the interest of men in embracing a career in nursing may have a meaningful resonance with the transformation of contemporary society, this process needs a judicious examination in order to protect academic integrity and, ultimately, prevent the reproduction of those inequalities in question. This analysis offers a

  13. Attitudes Toward Gender, Work, and Family among Female and Male Scientists in Germany and the United States

    Hanson, Sandra L.; Fuchs, Stefan; Aisenbrey, Silke; Kravets, Natalyia

    This research used a comparative approach and an elite framework to look at attitudes toward gender, work, and family among male and female scientists. The data came from the 1994 International Social Survey Program module measuring family and changing gender roles in (the former) East Germany, West Germany, and the United States. Research questions focused on the variation between the three samples in male scientists' attitudes regarding gender, work, and family; women's representation in science occupations; and the relation between the two. Another major concern was the extent to which female scientists express attitudes regarding gender, work, and family that resemble those of male scientists and the implications of these processes for increasing women's access to science. As predicted, male scientists in East Germany tended to have the most progressive attitudes (especially those regarding gender and work), East German women had the greatest access to science occupations, and there were virtually no sex differences in attitudes of East German scientists. West German male scientists were the most traditional on attitudes regarding gender and work, and U. S. male scientists tended to be the most traditional on attitudes regarding family. The attitudes of female scientists in West Germany and the United States reflected this larger trend, but there were sex differences within countries, with female scientists being more progressive than male scientists. Thus, the findings suggest that women s representation in science is related to the attitudes of male scientists regarding gender, work, and family. And although female scientists often hold quite similar attitudes as male scientists, there is considerable cross-country variation in how progressive the attitudes are and how similar men's and women's attitudes are. Implications for women's access to elite science occupations are discussed.

  14. Older Adults in Public Open Spaces: Age and Gender Segregation.

    Noon, Rinat Ben; Ayalon, Liat

    2018-01-18

    There is a substantial body of literature on the importance of the environment in the lives of older adults. Nonetheless, to date, there has been limited research on everyday activities of urban older adults in public open spaces. The present study examined the activities of older adults in public open spaces in Israel with a specific focus on age and gender as potential variables of relevance. Using still photography, we systematically photographed four sessions in two different public outdoor settings attended by older Israelis. Still photographs were converted to narrative descriptions, and then coded, quantified, and compared using descriptive statistics. The majority (311, 97%) of older adults arrived alone to the public setting. Of these, 44% formed a social group of two or more people, whereas the remaining older adults stayed alone. When social interactions occurred, they were primarily gender homogenous (69%); women were more likely to integrate in spontaneous social conversations and men were more likely to participate in common games. Our findings call attention to the important role played by the outdoor environment as a venue for social activities among older adults. The findings further stress the high levels of aloneness experienced by older adults, which do not seem to be alleviated by the mere attendance of public spaces. © The Author 2017.

  15. Gestational age, gender and parity specific centile charts for placental weight for singleton deliveries in Aberdeen, UK.

    Wallace, J M; Bhattacharya, S; Horgan, G W

    2013-03-01

    The weight of the placenta is a crude but useful proxy for its function in vivo. Accordingly extremes of placental weight are associated with adverse pregnancy outcomes while even normal variations in placental size may impact lifelong health. Centile charts of placental weight for gestational age and gender are used to identify placental weight extremes but none report the effect of parity. Thus the objective was to produce gender and gestational age specific centile charts for placental weight in nulliparous and multiparous women. Data was extracted from the Aberdeen Maternity and Neonatal Databank for all women delivering singleton babies in Aberdeen city and district after 24 weeks gestation. Gestational age specific centile charts for placental weight by gender and parity grouping (n = 88,649 deliveries over a 30 year period) were constructed using the LMS method after exclusion of outliers (0.63% of deliveries meeting study inclusion criteria). Tables and figures are presented for placental weight centiles according to gestational age, gender and parity grouping. Tables are additionally presented for the birth weight to placental weight ratio by gender. Placental weight and the fetal:placental weight ratio were higher in male versus female deliveries. Placental weight was greater in multiparous compared with nulliparous women. We present strong evidence that both gender and parity grouping influence placental weight centiles. The differences at any given gestational age are small and the effects of parity are greater overall than those of gender. In contrast the birth weight to placental weight ratio differs by gender only. These UK population specific centile charts may be useful in studies investigating the role of the placenta in mediating pregnancy outcome and lifelong health. Copyright © 2012 Elsevier Ltd.

  16. Age, gender, and percentage of circulating osteoprogenitor (COP) cells: The COP Study.

    Gunawardene, Piumali; Al Saedi, Ahmed; Singh, Lakshman; Bermeo, Sandra; Vogrin, Sara; Phu, Steven; Suriyaarachchi, Pushpa; Pignolo, Robert J; Duque, Gustavo

    2017-10-01

    Circulating osteoprogenitor (COP) cells are blood-borne cells which express a variety of osteoblastic markers and are able to form bone nodules in vivo. Whereas a high percentage of COP cells (%COP) is associated with vascular calcification, low %COP has been associated with disability and frailty. However, the reference range of %COP in age- and gender-matching populations, and the age-related changes in %COP remain unknown. A cross-sectional study was undertaken in 144 healthy volunteers in Western Sydney (20-90year-old, 10 male and 10 female subjects per decade). %COP was quantified by flow cytometry. A high inter-and intra-rater reliability was found. In average, in this healthy population average of %COP was 0.42. There was no significant difference in %COP among the age groups. Similarly, no significant difference was found in %COP with gender, weight, height or BMI. In addition, we identified a normal reference range of %COP of 0.1-3.8%. In conclusion, in addition to the identification of steady levels of COP cells with age, we also identified a normal reference range of %COP, which could be used in future studies looking at musculoskeletal diseases in older populations.

    2017-02-01

    Outpatient group psychotherapy is frequent within specialist services, recruits a mixed population, but effects are poorly documented. This study investigates long-term outcomes for patients with personality disorder (PD) treated in outpatient, psychodynamic groups within secondary mental health service. A naturalistic study (N = 103) with repeated assessments of process and clinical outcomes. Longitudinal statistics are linear mixed models. The main PDs were avoidant, borderline and NOS PD, mean number of PDs 1.4(SD0.7), 60% females and mean initial age 38(SD10) years. Mean treatment duration was 1.5(SD 0.9) years. Therapist alliance and experienced group climate was satisfactory and stable. Improvements were significant (symptom distress, interpersonal problems, occupational functioning and additional mental health services), irrespective of general PD-severity, but not of PD-type, age or gender. The study demonstrates PD NOS benefits across all outcomes, occupational improvements for avoidant PD, despite prevailing symptoms, but generally poorer outcomes for males and age >38 years. For borderline PD, experienced conflict was stronger, treatment duration shorter and outcomes poor for early drop-outs (28%). Psychodynamic group psychotherapy is a recommendable treatment for moderate PDs, which may address avoidant strategies, but may not meet clinical challenges of borderline PD. The outcome differences related to gender and age are noteworthy. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    Objective. In most cases, about the voice of the patient with female-to-male/gender identity disorder (FTM/GID), hormone therapy makes the voice low-pitched. In success cases, there is no need for phonosurgery. However, hormone therapy is not effective in some cases. We perform type 3 thyroplasty in these cases. Method. Hormone therapy was started in 2008 but did not lower the speaking fundamental frequencies (SFFs). We therefore performed TP3 under local anesthesia. Results. In our case, the...

  19. “It wasn’t my idea to come here!”: Ownership of the idea to immigrate as a function of gender, age, and culture.

    Rubin, Mark

    2017-01-01

    The present study investigated gender, age, and culture differences in immigrants’ ownership of the idea to immigrate to Australia. Married immigrants (N = 1,702) indicated whose idea it was to immigrate: their own, their partner’s, or a joint idea. Consistent with a patriarchal model, female immigrants were significantly less likely to claim ownership of the idea than male immigrants, and this difference partially mediated gender differences in post-immigration satisfaction. In addition, age...

  20. IMPACT OF EDUCATION, GENDER AND AGE ON CONSUMER LOYALTY

    Igor Klopotan

    2014-12-01

    Full Text Available In this paper the important parameters of customer loyalty and impact of education, gender and age of the respondents will be tested. The study was conducted in the Republic of Croatia, as part of research relevant parameters of customer loyalty, loyal consumer behavior and the role of social networks in building and maintaining a loyal behavior. The concept of loyalty has a strong foothold in marketing theories and in theories of intellectual capital companies. Loyalty has been related to the management of intellectual capital, especially relational capital, as a component of intellectual capital. In terms of loyalty, series of key parameters that describe it or have an effect on it, and thus impacting the company's business appear.

  1. [Perceiving gender or profession: the practical experience of male nursing students in the obstetrics and gynecology ward].

    Lee, Ya-Fen; Yang, Yu-O; Tu, Chia-Ling

    2013-06-01

    The impact of general gender stereotypes on nursing is severe and influential, especially with regard to male nursing students working in obstetrics and gynecology wards. This study examined the experience of male nursing students in obstetrics and gynecology wards. We used a phenomenological qualitative research approach and a sample of 10 male nursing students currently studying at a nursing college in central Taiwan. All participants had obstetrics and gynecology ward experience. Individual interviews were transcribed into the procedural record. Colaizzi content analysis analyzed and categorized research data. Based on participants practical experiences in the obstetrics and gynecology ward, the main stages of participants professional development through their internship experience included: (1) Unbalanced self-role recognition; (2) being defined by the gender framework (gender stereotypes); (3) the difference between male doctor and male nurse; (4) learning appropriate communication techniques; (5) mutual and empathetic understanding of the female psychology during childbirth; (6) gaining sources for positive feedback; (7) releasing the shackles of gender and gaining full insight into and comprehension of nursing functions; and (8) given the opportunity to learn. Through ongoing examination and learning, participant internships in the obstetrics and gynecology wards were significant and essential learning experiences that validated their necessity. Nursing schools and internship institutions alike must realize the importance of gender-equality education to the nursing profession. Medical institutions are encouraged to offer equal learning opportunities to male and female nursing students and provide targeted assistance to males to help them master clinical nursing care practices in the obstetrics and gynecology department.

  2. The relationship of age, gender, and IQ with the brainstem and thalamus in healthy children and adolescents: a magnetic resonance imaging volumetric study.

    Xie, Yuhuan; Chen, Yian Ann; De Bellis, Michael D

    2012-03-01

    In healthy children, there is a paucity of information on the growth of the brainstem and thalamus measured anatomically magnetic resonance imaging. The relations of age, gender, and age by gender with brainstem and thalamus volumes were analyzed from magnetic resonance brain images of 122 healthy children and adolescents (62 males, 60 females; ages 4 to 17). Results showed that age is a significant predictor of brainstem and thalamus volumes. The volume of the brainstem increases with age, while thalamus volume declines with age. The volume of the right thalamus is significantly larger than that of the left in both genders, with greater rightward asymmetry and greater thalamus to grey matter ratio in females. Males have larger brainstems, but these differences are not significant when covarying for cerebral volume. Larger thalami were associated with higher Verbal IQ. These normative pediatric data are of value to researchers who study these regions in neurodevelopmental disorders.

    We previously found that the empowerment of patients with type 2 diabetes mellitus can be strongly affected by gender and age in addition to self-managed diet and exercise behaviors and treatment. This study was to examine the effects of gender, age, family support, and treatment on the perceived stress and coping of patients with type 2 diabetes mellitus living with family. A survey was conducted of 140 adults with type 2 diabetes mellitus who were living with family. There was no significant difference in hemoglobin A1c (HbA1c) between male and female. Perceived stress and coping were measured with the Japanese version of the Appraisal of Diabetes Scale and the Lazarus Type Stress Coping Inventory. Stepwise regression analysis and path analysis were performed to identify factors that affect the perceived stress and coping of patients. (1) Perceived stress and coping were strongly affected by gender. (2) Perceived stress and coping were affected by age for males, but perceived stress was not affected by age for females. However, females showed a greater "psychological impact of diabetes" than did males. Females aged between 50 and 69 years engaged in active problem solving, but awareness of diabetes was low. (3) Treatment regimens had an effect on HbA1c for both sexes, and diet therapy affected the awareness of diabetes of males and coping of females. (4) For females, "sense of self-control" was strongly associated with coping, and those who were living with non-spouse family members had a greater psychological impact of diabetes than those living with only their spouse. (5) For males, coping was strongly affected by living with their spouse. The results suggest that perceived stress, coping, and diet regimen are deeply associated with gender and age and that a male with type 2 diabetes mellitus living with his spouse is strongly dependent on support from the spouse. It is important to take into account gender, age, and family environment to provide patients with

    To evaluate the relationship between androgen levels and subjective and objective measures of dry eye syndrome (DES). A total of 263 male patients from the Miami Veterans Affairs Medical Center eye clinic aged ≥50 were recruited for this prospective cross-sectional study. Patients completed Dry Eye Questionnaire 5, underwent tear film evaluation, and had serum androgen levels measured. The correlations between androgen levels, DES composite scores, DES symptoms, and global, lipid, and aqueous tear film parameters were evaluated. Two hundred sixty-three patients with a mean age of 69 (50-95) were examined. There was no linear association between composite DES scores (generated using latent class analysis) and androgen levels. However, eyes with high DES scores (0.95-1.0) had higher levels of sex hormone-binding globulin (P = 0.03) and lower levels of dehydroepiandrosterone sulfate (DHEAS) (P = 0.02), androstenedione (A) (P = 0.02), and androstane-3α,17β-diol glucuronide (P = 0.03) compared to eyes with intermediate (0.05-0.95) or low (0-0.05) scores. There were no strong correlations between tear film measures and androgen levels. Regarding global parameters, a weak inverse correlation was found between corneal staining and A (r = -0.17, P = 0.009). For lipid parameters, a weak correlation existed between tear breakup time (TBUT) and A (r = 0.15, P = 0.02). When considering aqueous and lipid deficiency independently, the association between TBUT and A existed only with aqueous tear deficiency (r = 0.66, P = 0.002). Regarding aqueous parameters, a weak correlation existed between Schirmer test and DHEAS (r = 0.13, P = 0.047) and A (r = 0.21, P = 0.001). There was a weak correlation between higher levels of androstenedione and healthier global, lipid, and aqueous tear film parameters.

    To determine the frequency of hypoglycemia in small for gestational age neonates based on gestational age, gender, birth weight and mode of delivery. Study Design: Cross sectional study. Place and Duration of Study: Neonatal Intensive Care Unit (NICU), Military Hospital Rawalpindi, from Dec 2011 to Jul 2012. Material and Methods: We included 383 small for gestational age (SGA) neonates admitted in NICU. Blood glucose levels were checked in all neonates. Variables included in study were gestational age, gender, birth weight and mode of delivery. Results: Out of 383 SGA neonates enrolled by non-probability consecutive sampling, 191 (49.87%) were males and 192 (50.13%) were females. Out of these 203 (53%) were preterm, 165 (43.08%) were delivered at term and 15 (3.92%) were post-term SGA neonates with mean gestational age of 34 weeks 5 days. Out of the total 383 SGA neonates 208 (54.31%) developed hypoglycemia during stay in NICU and 175 (45.69%) remained euglycemic. Extremely low birth weight (ELBW) neonates were at highest risk to develop hypoglycemia (82.35%). It was seen that SGA neonates delivered by instrumental vaginal delivery had highest risk of developing hypoglycemia i.e. 20 (76.92) out of 26 neonates. Out of 103 vaginal deliveries 41 (39.81%) had hypoglycemia and out of 254 Caesarean section 147 (57.87%) had hypoglycemia. Conclusion: Low birth weight neonates delivered by instrumental vaginal delivery were found to be at a higher risk of developing hypoglycemia. (author)

    Fully automated analysis programs have been applied more and more to aid for the reading of regional cerebral blood flow SPECT study. They are increasingly based on the comparison of the patient study with a normal database. In this study, we evaluate the ability of Three-Dimensional Stereotactic Surface Projection (3 D-S.S.P.) to isolate effects of age and gender in a previously studied normal population. The results were also compared with those obtained using Statistical Parametric Mapping (S.P.M.99). Methods Eighty-nine 99m Tc-E.C.D.-SPECT studies performed in carefully screened healthy volunteers (46 females, 43 males; age 20 - 81 years) were analysed using 3 D-S.S.P.. A multivariate analysis based on the general linear model was performed with regions as intra-subject factor, gender as inter-subject factor and age as co-variate. Results Both age and gender had a significant interaction effect with regional tracer uptake. An age-related decline (p < 0.001) was found in the anterior cingulate gyrus, left frontal association cortex and left insula. Bilateral occipital association and left primary visual cortical uptake showed a significant relative increase with age (p < 0.001). Concerning the gender effect, women showed higher uptake (p < 0.01) in the parietal and right sensorimotor cortices. An age by gender interaction (p < 0.01) was only found in the left medial frontal cortex. The results were consistent with those obtained with S.P.M.99. Conclusion 3 D-S.S.P. analysis of normal r.C.B.F. variability is consistent with the literature and other automated voxel-based techniques, which highlight the effects of both age and gender.

    Background. Understanding the physiological, chemical, and biophysical characteristics of the skin helps us to arrange a proper approach to the management of skin diseases. Objective. The aim of this study was to measure 6 biophysical characteristics of normal skin (sebum content, hydration, transepidermal water loss (TEWL), erythema index, melanin index, and elasticity) in a normal population and assess the effect of sex, age, and body location on them. Methods. Fifty healthy volunteers in 5 age groups (5 males and females in each) were enrolled in this study. A multifunctional skin physiology monitor (Courage & Khazaka electronic GmbH, Germany) was used to measure skin sebum content, hydration, TEWL, erythema index, melanin index, and elasticity in 8 different locations of the body. Results. There were significant differences between the hydration, melanin index, and elasticity of different age groups. Regarding the locations, forehead had the highest melanin index, where as palm had the lowest value. The mean values of erythema index and melanin index and TEWL were significantly higher in males and anatomic location was a significant independent factor for all of 6 measured parameters. Conclusion. Several biophysical properties of the skin vary among different gender, age groups, and body locations. PMID:22536139

    Full Text Available Until 2030 the ulcer mortality will have a growing trend as estimated by the World Health Organization. Detection of countries and population groups with high risks for the ulcer mortality is possible using forecast method. The authors made a forecast of mortality rate from complicated ulcer disease in males and females and their age groups (15-24, 25-34, 35-54, 55-74, over 75, 15 - over 75 in our country. The study included data of the World Health Organization Database from 1991 to 2012. The work analyzed absolute all-Ukrainian numbers of persons of both genders died from the ulcer causes (К25-К27 coded by the 10th International Diseases Classification. The relative mortality per 100 000 of alive persons of the same age was calculated de novo. The analysis of distribution laws and their estimation presents a trend of growth of the relative mortality. A remarkable increase of deaths from the ulcer disease is observed in males and females of the age after 55 years old. After the age of 75 years this trend is more expressed.

  12. Gender and sexual orientation differences in cognition across adulthood: age is kinder to women than to men regardless of sexual orientation.

    Maylor, Elizabeth A; Reimers, Stian; Choi, Jean; Collaer, Marcia L; Peters, Michael; Silverman, Irwin

    2007-04-01

    Despite some evidence of greater age-related deterioration of the brain in males than in females, gender differences in rates of cognitive aging have proved inconsistent. The present study employed web-based methodology to collect data from people aged 20-65 years (109,612 men; 88,509 women). As expected, men outperformed women on tests of mental rotation and line angle judgment, whereas women outperformed men on tests of category fluency and object location memory. Performance on all tests declined with age but significantly more so for men than for women. Heterosexuals of each gender generally outperformed bisexuals and homosexuals on tests where that gender was superior; however, there were no clear interactions between age and sexual orientation for either gender. At least for these particular tests from young adulthood to retirement, age is kinder to women than to men, but treats heterosexuals, bisexuals, and homosexuals just the same.

  13. Aging differentially affects male and female neural stem cell neurogenic properties

    Full Text Available Jay Waldron1, Althea McCourty1, Laurent Lecanu1,21The Research Institute of the McGill University Health Centre, Montreal, Canada; 2Department of Medicine, McGill University, Montreal, Quebec, CanadaPurpose: Neural stem cell transplantation as a brain repair strategy is a very promising technology. However, despite many attempts, the clinical success remains very deceiving. Despite clear evidence that sexual dimorphism rules many aspects of human biology, the occurrence of a sex difference in neural stem cell biology is largely understudied. Herein, we propose to determine whether gender is a dimension that drives the fate of neural stem cells through aging. Should it occur, we believe that neural stem cell sexual dimorphism and its variation during aging should be taken into account to refine clinical approaches of brain repair strategies.Methods: Neural stem cells were isolated from the subventricular zone of three- and 20-month-old male and female Long-Evans rats. Expression of the estrogen receptors, ERα and ERβ, progesterone receptor, androgen receptor, and glucocorticoid receptor was analyzed and quantified by Western blotting on undifferentiated neural stem cells. A second set of neural stem cells was treated with retinoic acid to trigger differentiation, and the expression of neuronal, astroglial, and oligodendroglial markers was determined using Western blotting.Conclusion: We provided in vitro evidence that the fate of neural stem cells is affected by sex and aging. Indeed, young male neural stem cells mainly expressed markers of neuronal and oligodendroglial fate, whereas young female neural stem cells underwent differentiation towards an astroglial phenotype. Aging resulted in a lessened capacity to express neuron and astrocyte markers. Undifferentiated neural stem cells displayed sexual dimorphism in the expression of steroid receptors, in particular ERα and ERβ, and the expression level of several steroid receptors increased

  14. Long live the liver: immunohistochemical and stereological study of hepatocytes, liver sinusoidal endothelial cells, Kupffer cells and hepatic stellate cells of male and female rats throughout ageing.

    Male/female differences in enzyme activity and gene expression in the liver are known to be attenuated with ageing. Nevertheless, the effect of ageing on liver structure and quantitative cell morphology remains unknown. Male and female Wistar rats aged 2, 6, 12 and 18 months were examined by means of stereological techniques and immunohistochemical tagging of hepatocytes (HEP), liver sinusoidal endothelial cells (LSEC), Kupffer cells (KC) and hepatic stellate cells (HSC) in order to assess the total number and number per gram of these cells throughout life. The mean cell volume of HEP and HSC, the lobular position and the collagen content of the liver were also evaluated with stereological techniques. The number per gram of HSC was similar for both genders and was maintained throughout ageing. The mean volume of HSC was also conserved but differences in the cell body and lobular location were observed. Statistically significant gender differences in HEP were noted in young rats (females had smaller and more binucleated HEP) but were attenuated with ageing. The same occurred for KC and LSEC, since the higher number per gram in young females disappeared in older animals. Liver collagen increased with ageing but only in males. Thus, the numbers of these four cell types are related throughout ageing, with well-defined cell ratios. The shape and lobular position of HSC change with ageing in both males and females. Gender dimorphism in HEP, KC and LSEC of young rat liver disappears with ageing.

  15. Effects of uncertainty, transmission type, driver age and gender on brake reaction and movement time.

    Warshawsky-Livne, Lora; Shinar, David

    2002-01-01

    Braking time (BT) is a critical component in safe driving, and various approaches have been applied to minimize it. This study analyzed the components of BT in order to assess the effects of age, gender, vehicle transmission type, and event uncertainty, on its two primary components, perception-reaction time and brake-movement time. Perception-reaction time and brake-movement time were measured at the onset of lights for 72 subjects in a simulator. The six experimental conditions were three levels of uncertainty conditions (none, some, and some + false alarms) and two types of transmission (manual and automatic). The 72 subjects, half male and half female, were further divided into three age groups (mean of 23, 30, and 62 years). Each subject had 10 trials in each of the three levels of uncertainty conditions. Transmission type did not significantly affect either perception-reaction time or brake-movement time. Perception-reaction time increased significantly from 0.32 to 0.42 s (P brake-movement time did not change. Perception-reaction time increased (from 0.35 to 0.43 s) with age but brake-movement time did not change with age. Gender did not affect perception-reaction time but did affect brake-movement time (males 0.19 s vs. females 0.16 s). At 90 km/h, a car travels 0.25 m in 0.01 s. Consequently, even such small effects multiplied by millions of vehicle-kilometers can contribute to significant savings in lives and damages.

The objective of this study was to analyze possible relationships and differences between PAL, QoL and use of medications in the elderly. A total of 192 subjects (≥ 60 years were selected by stratified random sampling according to census sector. The following assessment instruments were used: a Modified Baecke Questionnaire for older adults, b Medical Outcomes Study – 36-Item Short Form Health Survey, and c Sociodemographic and Health Factors Questionnaire. Descriptive statistics and parametric and nonparametric tests were used (p < 0.05. a With respect to chronological age, significant differences between groups were only observed for PAL, with G1 (60-69 years being more active than the other groups. b With respect to gender irrespective of age, analysis showed a difference in QoL and in the number of medications, with men reporting better perceived QoL and using fewer medications. c With respect to gender but considering chronological age, differences in PAL, QoL and medication use were observed between genders for specific age groups. In conclusion, in the elderly a PAL is low, declines even more during advanced age and is higher in men than in women during the first decade of old age, and b men report better perceived QoL and use fewer medications than women.

    2015-10-01

    Full Text Available Fundamental motor skills are the basis for participation in more advanced lifetime activities. Whereas considerable research has been reported on motor behavior of children, much less is known about performance in later years, especially adulthood. Therefore, the aim of this study was to examine age and gender differences on fundamental motor skills (FMS ability across three age groups: children (M = 9.37 yr., SD = 1.26, adolescents (M = 14.80 yr., SD = 2.04 and young-adults (M = 19.88 yr., SD = 2.72. Participants (n = 114 were assessed on five locomotor skills (run, gallop, slide, hop, and distance jump and five object control skills (bounce, catch, overhand throw, strike and kick using the Test for Fundamental Motor Skills, which is a process-oriented instrument. ANOVA results comparing gender and group revealed no significant interactions. Moreover, main effects for group were found for three individual skills: galloping –adolescents and young-adults performed better than children (p < .01–, throwing –children and adolescents performed better than young-adults (p < .01 –, and kicking –young-adults performed better than children and adolescents (p < .05–. Also, we found main effects for gender for total FMS ability (p < .01, locomotor subscale (p < .05 and object control subscale (p < .01, and for six individual motor skills: run (p < .05, jump (p < .05, throw (p < .01, kick (p < .01, bounce (p < .01 and strike (p < .01; males outperformed females for all the skills. However, in view of total FMS ability, locomotor skills and object control skills results suggest similar performance across ages. Therefore, it is important to enhance fundamental motor skills at all ages, as an option to help individuals engage in physical activities.

  18. Gender- and Gestational Age-Specific Body Fat Percentage at Birth.

    Hawkes, Colin P

    2011-08-08

    Background: There is increasing evidence that in utero growth has both immediate and far-reaching influence on health. Birth weight and length are used as surrogate measures of in utero growth. However, these measures poorly reflect neonatal adiposity. Air-displacement plethysmography has been validated for the measurement of body fat in the neonatal population. Objective: The goal of this study was to show the normal reference values of percentage body fat (%BF) in infants during the first 4 days of life. Methods: As part of a large population-based birth cohort study, fat mass, fat-free mass, and %BF were measured within the first 4 days of life using air-displacement plethsymography. Infants were grouped into gestational age and gender categories. Results: Of the 786 enrolled infants, fat mass, fat-free mass, and %BF were measured in 743 (94.5%) infants within the first 4 days of life. %BF increased significantly with gestational age. Mean (SD) %BF at 36 to 37 weeks\\' gestation was 8.9% (3.5%); at 38 to 39 weeks\\' gestation, 10.3% (4%); and at 40 to 41 weeks\\' gestation, 11.2% (4.3%) (P < .001). Female infants had significantly increased mean (SD) %BF at 38 to 39(11.1% [3.9%] vs 9.8% [3.9%]; P = .012) and at 40 to 41 (12.5% [4.4%] vs 10% [3.9%]; P < .001) weeks\\' gestation compared with male infants. Gender- and gestational age-specific centiles were calculated, and a normative table was generated for reference. Conclusion: %BF at birth is influenced by gestational age and gender. We generated accurate %BF centiles from a large population-based cohort.

    Choosing the antimicrobial agent for initial therapy of urinary tract infection (UTI) is usually empirical and should consider the prevalence of uropathogens in different age groups and gender. To establish prevalence rates of uropathogens in community-acquired UTI in relation to age and gender. Cross-sectional study conducted in the emergency department (ED) of a general hospital, from January to December, 2010, in patients younger than 15 years old who had clinical suspicion of UTI and collected quantitative urine culture. UTI was defined as urine culture with growth of a single agent > 100.000 colony forming units (cfu)/mL in a midstream collection or ≥ 50.000 cfu/mL in urethral catheterization. There were 63.464 visits to ED. 2577 urine cultures were obtained, of whom 291 were positive for UTI (prevalence = 11.3% of clinical suspicion and 0.46% of visits), 212 cases (72.8%) in females, median age = 2.6 years. The predominant uropathogen was E. coli (76.6%), followed by Proteus mirabilis (10.3%) and Staphylococcus saprophyticus (4.1%). Among infants 10 years (24.4% vs 0.4%; OR = 79.265; p 10 years and Proteus mirabilis in males.

  1. How avoidant attachment influences subjective well-being: an investigation about the age and gender differences.

    Li, Tianyuan; Fung, Helene H

    2014-01-01

    Intimate relationship is a significant factor that influences older adults' subjective well-being. Avoidant attachment reflects a basic working model regarding interpersonal relationships. The current study aims to test how age and gender moderate the effect of avoidant attachment to spouse on subjective well-being. Fifty-six married couples aged from 20 to 79 years in Hong Kong were recruited for the study. Their avoidant attachment to spouse and subjective well-being were measured by questionnaires. In general, avoidant attachment to spouse was found to undermine subjective well-being. More importantly, age significantly moderated the negative association between avoidant attachment and subjective well-being, but the direction of the moderating effect was opposite for husbands and wives. Compared with their younger counterparts, the detrimental effect of avoidant attachment on subjective well-being was weaker for older wives but stronger for older husbands. The results suggest that marital relationship may play different roles in different life stages for the two genders. In later adulthood, males may become more dependent on the marital relationship to maintain subjective well-being, whereas females can be relatively independent.

  2. A field study on thermal comfort in an Italian hospital considering differences in gender and age.

    Del Ferraro, S; Iavicoli, S; Russo, S; Molinaro, V

    2015-09-01

    The hospital is a thermal environment where comfort must be calibrated by taking into account two different groups of people, that is, patients and medical staff. The study involves 30 patients and 19 medical staff with a view to verifying if Predicted Mean Vote (PMV) index can accurately predict thermal sensations of both groups also taking into account any potential effects of age and gender. The methodology adopted is based on the comparison between PMV values (calculated according to ISO 7730 after having collected environmental data and estimated personal parameters) and perceptual judgments (Actual Mean Vote, AMV), expressed by the subjects interviewed. Different statistical analyses show that PMV model finds his best correlation with AMV values in a sample of male medical staff under 65 years of age. It has been observed that gender and age are factors that must be taken into account in the assessment of thermal comfort in the hospital due to very weak correlation between AMV and PMV values.

    We aimed to describe and compare gender norms among 10- to 14-year-olds versus 15- to 24-year-olds and to conduct a rigorous evaluation of the GEM Scale's performance among these two age groups. We conducted a two-stage cluster-sampled survey among 387 females and 583 males, aged 10-24 years, in rural and urban communities near Kampala, Uganda. We applied, assessed, and adapted the GEM Scale (Pulerwitz and Barker, 2008), which measures views toward gender norms in four domains. We describe levels of support for (in)equitable norms, by gender and age, and associations with key health outcomes (partner violence). Confirmatory factor analysis and multi-group measurement invariance analysis were used to assess scale performance. All participants reported high levels of support for inequitable gender norms; 10- to 14-year-olds were less gender equitable than their older counterparts. For example, 74% of 10- to 14-year-olds and 67% of 15- to 24-year-olds agreed that "a woman should tolerate violence to keep her family together." Comparing responses from males and females indicated similar support for gender inequity. Analyses confirmed a one-factor model, good scale fit for both age groups, and that several items from the scale could be dropped for this sample. The ideal list of items for each age group differed somewhat but covered all four scale domains in either case. An 18-item adapted scale was used to compare mean GEM Scale scores between the two age groups; responses were significantly associated with early sexual debut and partner violence. Young people internalize gender norms about sexual and intimate relationships, and violence, at early ages. Programs to address negative health outcomes should explicitly address inequitable gender norms and more consistently expand to reach younger age groups. In this first application of the GEM Scale among 10- to 14-year-olds, we confirm that it is a valid measure in this setting. Copyright © 2016 Society for Adolescent

    Comparison of 41 female and 15 male older adults participating in Universities of the Third Age found the genders approach retirement differently. Women want to experience freedom and make up for lost opportunities; men prefer to "sit." However, men with active interests before retirement continued activity in the Third Age. (SK)

    Flood mortality is analyzed and compared between Portugal and Greece. Flood fatality incidents are explored and compared in terms of their temporal evolution, spatial distribution, deadliest flood types, surrounding environments, gender and age of the victims. A common flood fatalities database for the period 1960-2010 was formed by merging the DISASTER database for Portugal and the Greek database previously built from documental sources. Each entry of the database, corresponding to a flood fatal incident has the following attributes: (i) ID number of the flood case; (ii) the flood type (riverine flood, flash flood, urban flood, or not defined type); (iii) date (day-month-year); (iv) location (x and y coordinates); (v) number of fatalities; (vi) surrounding environment where the flood fatal incident occurred (i.e. outdoors on foot, outdoors inside a vehicle, or inside a building). (vii) gender of the victim (male, female, or gender not reported); (viii) age of the victim (65 years). Excluding the outlier 1967 flash flood event occurred in the Lisbon metropolitan area that caused 522 fatalities, Portugal recorded 114 flood fatalities (related to 80 flood cases) and Greece registered 189 fatalities (related to 57 flood cases). Results identified decreasing mortality trend in both countries, despite some fluctuations irregularly distributed over time. Since the 1980's the number of flood cases with multiple fatalities has been gradually decreasing. In both Greece and Portugal flash floods were responsible for more than 80% of flood mortality and the main metropolitan areas of each country (Athens and Lisbon) presented a clustering of fatalities, attributed to the higher population density combined with the presence of flood-prone areas. Indoor fatalities have been gradually reducing with time, whereas vehicle-related deaths have been rising in both countries. In both countries the majority of flood victims are males, indicating that males are more vulnerable to fatal

    Dopamine transporter imaging is a valuable tool to investigate the integrity of the dopaminergic neurons. To date, several reports have shown an age-associated decline in dopamine transporters in healthy volunteers. Although animal studies suggest an effect of gender on dopamine transporter density, this gender effect has not yet been confirmed in human studies. To study the influence of age and gender on dopamine transporter imaging in healthy volunteers, we performed single-photon emission tomography imaging with [ 123 I]FP-CIT to quantify dopamine transporters. Forty-five healthy volunteers (23 males and 22 females) were included, ranging in age from 18 to 83 years. SPET imaging was performed 3 h after injection of ±110 MBq [ 123 I]FP-CIT. An operator-independent volume of interest analysis was used for quantification of [ 123 I]FP-CIT binding in the striatum. The ratio of specific striatal to non-specific [ 123 I]FP-CIT binding was found to decrease significantly with age. Moreover, we found a high variance in [ 123 I]FP-CIT binding in young adults. Finally, females were found to have significantly higher [ 123 I]FP-CIT binding ratios than males. This effect of gender on [ 123 I]FP-CIT binding ratios was not related to age. The results of this study are consistent with findings from previous studies, which showed that dopamine transporter density declines with age. The intriguing finding of a higher dopamine transporter density in females than in males is in line with findings from animal studies. (orig.)

    Full Text Available The aim of this study was to test effects of age, gender, and sire line on dairy cattle behaviour. We have analyzed results of ethological tests for 40 Holstein breed animals (23 males and 17 females, offsprings of three sires. Maintenance behaviour were observed at the age of 90, 130 and 170 days. Behaviour in the maze was conducted at the age of 119 days, an open-field test was applied at the age of 124, 168, and 355 days. The social behaviour was determined by feeding on 155th day of the age. The times and the number of periods in all activities of maintenance behaviour were changing significantly (P<0.001 according to the age. The total time of lying, lying with ruminating, ruminating, feeding was increasing from the age of 90 days to the age of 170 days, on the other hand the time of standing was decreasing. The times of total lying, lying with ruminating, total ruminating, feeding were increased, and time of standing was decreased from the age of 90 days to the age of 170 days. Calves spent more time lying on the left side than on the right side. The number of ruminating periods was increasing according to the age. Eating periods were decreasing from the age of 90 to 170 days. The most of lying periods were recorded at the age of 130 days. The differences between sex were found in total time of lying, lying on the right side (P<0.05, and the males rest longer and had more periods of lying than females. We have found differences in times of feeding (P<0.001, total lying, standing (P<0.01, and lying on the left side (P<0.05 according to sire by comparing behaviour of the calves. Sire genotypes were significantly manifested in period number of total lying (P<0.001, lying on the right side, feeding (P<0.01, and standing (P<0.05. Males stood in the first part of maze longer than females (P<0.001, also length of total standing was longer by bulls (P<0.01. Heifers took shorter time to leave the maze than bulls (P<0.05.

  8. Attachment and self-evaluation in Chinese adolescents: age and gender differences.

    Song, Hairong; Thompson, Ross A; Ferrer, Emilio

    2009-10-01

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

    2018-01-12

    To evaluate the impact of age and gender on the international classification of functioning, disability and health (ICF)-based assessment for chronic low back pain. Two hundred forty-four chronic low back pain patients (52% female) with a mean age of 49 years (SD =17.64) were interviewed with the comprehensive ICF core set for activities and participation, and environmental factors. After conducting explorative factor analysis, the impact of age and gender on the different factors was analyzed using analyzes of variances. Results revealed that older patients experienced more limitations within "self-care and mobility" and "walking" but less problems with "transportation" compared to younger patients. Older or middle-aged low back pain patients further perceived more facilitation through "architecture and products for communication", "health services", and "social services and products for mobility" than younger patients. Regarding gender differences, women reported more restriction in "housework" than men. An interaction effect between age and gender was found for "social activities and recreation" with young male patients reporting the highest impairment. The study demonstrated that the comprehensive ICF core set classification for chronic low back pain is influenced by age and gender. This impact is relevant for ICF-based assessments in clinical practice, and should be considered in intervention planning for rehabilitative programs. Implications for rehabilitation It is important to consider age and gender differences when classifying with the ICF. The intervention planning based on the ICF should focus on improvement of bodily functioning and mobility in older patients, facilitation of household activities in women, consideration of work-life balance and recreation (e.g., through mindfulness based stress reduction), and reduction of dissatisfaction with rehabilitation in younger patients. It is important to offer patients the opportunity to participate in

  11. Effects of Maternal Anxiety Disorders on Infant Self-Comforting Behaviors: The Role of Maternal Bonding, Infant Gender and Age.

    Müller, Mitho; Tronick, Ed; Zietlow, Anna-Lena; Nonnenmacher, Nora; Verschoor, Stephan; Träuble, Birgit

    We investigated the links between maternal bonding, maternal anxiety disorders, and infant self-comforting behaviors. Furthermore, we looked at the moderating roles of infant gender and age. Our sample (n = 69) comprised 28 mothers with an anxiety disorder (according to DSM-IV criteria) and 41 controls, each with their 2.5- to 8-month-old infant (41 females and 28 males). Infant behaviors were recorded during the Face-to-Face Still-Face paradigm. Maternal bonding was assessed by the Postpartum Bonding Questionnaire. Conditional process analyses revealed that lower maternal bonding partially mediated between maternal anxiety disorders and increased self-comforting behaviors but only in older female infants (over 5.5 months of age). However, considering maternal anxiety disorders without the influence of bonding, older female infants (over 5.5 months of age) showed decreased rates of self-comforting behaviors, while younger male infants (under 3 months of age) showed increased rates in the case of maternal anxiety disorder. The results suggest that older female infants (over 5.5 months of age) are more sensitive to lower maternal bonding in the context of maternal anxiety disorders. Furthermore, results suggest a different use of self-directed regulation strategies for male and female infants of mothers with anxiety disorders and low bonding, depending on infant age. The results are discussed in the light of gender-specific developmental trajectories. © 2016 S. Karger AG, Basel.

    Xiao-ying Yao

    2012-01-01

    Full Text Available Background. Evidences are accumulating that age and gender have great impact on the distribution of stroke risk factors. Such data are lacking in Chinese population. Methods. 1027 patients with first-ever ischemic stroke (IS were recruited and divided into young adult (80 years groups according to stroke onset ages. Vascular risk factors were collected and compared among groups. Results. Female patients were globally older than male patients at stroke onset and having higher prevalence of diabetes mellitus (DM, heart diseases, and atrial fibrillation (AF. However, females were less likely to drink heavily or smoke than males. Young patients had a much higher proportion of smoking and drinking than middle-aged and very old patients and the highest family history of hypertension, while very old patients had the highest prevalence of heart diseases and AF but lowest proportion of positive family history of vascular diseases. Hypertension and DM were equally frequent among three groups. Conclusion. Our study showed that vascular risk factors had a specific age and gender distribution pattern in Chinese IS patients. Secondary prevention strategy should emphasize on the control of different risk factors based on patient’s age and gender.

    2016-03-01

    The purpose of this study was to analyze the anthropometric data from MRI images that were obtained from the non-arthritic knees in Asian adults, and to identify the existence of morphologic differences between age groups. This cross-sectional study included knee MR images of 535 patients (273 males, 262 females) taken for the evaluation of soft-tissue injuries, excluding cases with cartilage defect and malalignment. The age, gender, height, and BMI were also assessed. The patients were grouped into three different 20-year age groups (20-39, 40-59, and 60-79). The MRI analysis was performed on the anthropometric parameters of distal femur and posterior tibial slope. Age-related differences were found in femoral width, distance from the distal and posterior cartilage surface to the medial/lateral epicondyle, medial posterior condylar offset (PCO), and posterior condylar angle (PCA) (all P age groups was found in most parameters, but not in PCA, distance from the posterior cartilage surface to the medial epicondyle, or medial tibial slope. We found anthropometric differences among age groups exist in most of distal femoral parameters, but not in posterior tibial slope. The results of this study can be used by manufacturers to modify prostheses to be suitable for the future Asian elderly population.

    Background: Little is known about the variation in exposure to toxic metals by age and gender and other potential modifying factors. We evaluated age and gender differences by measurements of metal/element concentrations in urine in a rural population in Matlab, Bangladesh, in three age groups: 8–12 (N=238), 14–15 (N=107) and 30–88 (N=710) years of age, living in an area with no point sources of metal exposure but where elevated water arsenic concentrations are prevalent. Results: We found marked differences in urine concentrations of metals and trace elements by gender, age, tobacco use, socioeconomic and nutritional status. Besides a clearly elevated urinary arsenic concentration in all age groups (medians 63–85 μg As/L), and despite the low degree of contamination from industries and traffic, the urine concentrations of toxic metals such as cadmium and lead were clearly elevated, especially in children (median 0.31 μg Cd/L and 2.9 μg Pb/L, respectively). In general, women had higher urinary concentrations of toxic metals, especially Cd (median 0.81 μg/L) compared to men (0.66 μg/L) and U (median 10 ng/L in women, compared to 6.4 ng/L in men), while men had higher urinary concentrations of the basic and essential elements Ca (69 mg/L in men, 30–50 years, compared to 52 mg/L in women), Mg (58 mg/L in men compared to 50 mg/L in women), Zn (182 μg/L in men compared to 117 μg/L in women) and Se (9.9 μg/L in men compared to 8.7 μg/L in women). Manganese was consistently higher in females than in males in all age groups, suggesting a biological difference between females and males in Mn metabolism. Increasing socioeconomic status decreased the toxic metal exposure significantly in children and especially in men. Poor iron status was detected in 17% of children, adolescents and women, but only in 6% of men. Also zinc deficiency was more prevalent in females than in males. Conclusions: Women and children seemed to be more at risk for toxic metal

    Full Text Available OBJETIVO: Analisar as relações de gênero vivenciadas por adolescentes do sexo masculino e como elas contribuem para torná-los vulneráveis à gravidez na adolescência. MÉTODOS: Estudo qualitativo realizado em Campo Grande, Mato Grosso do Sul, em 2003. Participaram 13 adolescentes masculinos com menos de 20 anos, com um único filho de até 11 meses, cuja mãe estava na mesma faixa etária do pai. Realizaram-se entrevistas semi-estruturadas gravadas. Após transcrição, procedeu-se à análise temática de conteúdo. RESULTADOS: Identificaram-se estereótipos de gênero em que se destacavam papéis de líder, provedor e ativo sexualmente, bem como a rejeição a ser cuidador. Esses papéis apareceram consolidados principalmente na perspectiva dos entrevistados acerca do trabalho como marcador de sua condição de homem e provedor da família. A liderança dos adolescentes prevaleceu no relacionamento com a mãe de seu filho, notadamente na iniciativa das relações sexuais e no uso de contraceptivos. A gravidez foi considerada por eles como "por acaso" e inesperada, mas a paternidade foi vivenciada como uma prova final de sua condição de homens adultos. CONCLUSÕES: Verificou-se a condição de vulnerabilidade dos adolescentes para a paternidade em virtude da socialização de gênero nos moldes tradicionais. Isso foi evidenciado com a ausência dos papéis relativos ao cuidado consigo próprio e com os outros, com a incorporação precoce de papéis de dominação sexual masculina e de trabalhador e pai, ou seja, deixar de ser criança e alcançar a condição de homem.OBJECTIVE: To analyze gender relations perceived by male adolescents and how they contribute to making them more vulnerable to pregnancy during adolescence.

    The influence of gender and age on risk factor prediction of coronary artery calcification (CAC) in symptomatic patients is unclear. From the European Calcific Coronary Artery Disease (EURO-CCAD) cohort, we retrospectively investigated 6309 symptomatic patients, 62% male, from Denmark, France, Germany, Italy, Spain and USA. All of them underwent risk factor assessment and CT scanning for CAC scoring. The prevalence of CAC among females was lower than among males in all age groups. Using multivariate logistic regression, age, dyslipidaemia, hypertension, diabetes and smoking were independently predictive of CAC presence in both genders. In addition to a progressive increase in CAC with age, the most important predictors of CAC presence were dyslipidaemia and diabetes (β = 0.64 and 0.63, respectively) in males and diabetes (β = 1.08) followed by smoking (β = 0.68) in females; these same risk factors were also important in predicting increasing CAC scores. There was no difference in the predictive ability of diabetes, hypertension and dyslipidaemia in either gender for CAC presence in patients aged 70, only dyslipidaemia predicted CAC presence in males and only smoking and diabetes were predictive in females. In symptomatic patients, there are significant differences in the ability of conventional risk factors to predict CAC presence between genders and between patients aged role of age in predicting CAC presence.

  4. Sociocultural Factors of Survival of Males and Females in Economically Active Age: a Regional Analysis

    Evgeniya Khasanovna Tukhtarova

    2018-03-01

    Full Text Available The period, when a person starts and completes his or her professional carrier and labour participation, in general, coincides with the age when the self-preservation behaviour develops. It is a time when a person aims for a healthy and safe lifestyle. During this period, an individual assumes the main standards, values of the self-preservation behaviour inherent in an ethnic, social and cultural macro-environment. To research the sociocultural factors of survival, we applied econometric modelling to demographic processes using the discrete and probabilistic indicators of the mortality tables of male and female in economically active age. The econometric model included the elements of spatiotemporal characteristics of territories. These characteristics are interrelated with the indicators of survival probability and the indicator of average life expectancy in the regions of Russia. We choose the major sociocultural factors by the correlation ratio of indicators and their sensitivity. The econometric analysis has revealed a high degree of sensitivity of a territorial variation of demographic and sociocultural factors in the regions of Russia, including a gender aspect. The most significant socio-economic factors, which determine the self-preservation behaviour of males, are the following: 1 the size of Gross Regional Product per capita; 2 quality of health infrastructure; 3 fixed investments; 4 population with monetary income under the subsistence minimum (share coefficient of income differentials. The female have the same hierarchy of socio-economic factors, except for the sensitivity of variables to the regional differentiation of signs. The household poverty factor has little significance for the women and it is the main difference between male and female. The built model has shown the predictive importance in the assessment of the above-mentioned factors in short and medium-term prospects.

  5. Where and when adolescents use tobacco, alcohol, and marijuana: comparisons by age, gender, and race.

    Goncy, Elizabeth A; Mrug, Sylvie

    2013-03-01

    This study examined the location and time of adolescent use of cigarettes, alcohol, and marijuana. Age, gender, and racial differences in location and time of use were studied for each substance. Using cross-sectional data collected through the schoolwide Pride Survey, 20,055 students between the ages of 10 and 19 years (53.6% female, 55.1% Black, 44.9% White) in one metropolitan area reported on their frequency of cigarette, alcohol, and marijuana use, as well as the location and time of use of each substance. Chi-square tests compared the rates, locations, and times for each substance across boys and girls; Black and White students; and early, middle, and late adolescents. Older adolescents reported higher rates of substance use at friends' homes, at school, and in cars and lower rates of alcohol use at home compared with younger youth. Males were more likely to report alcohol and marijuana use at school and on weeknights and alcohol use in cars, whereas females were more likely to report alcohol and marijuana use on the weekends. No gender differences emerged for times and locations of cigarette use. Compared with Black youth, White adolescents were more likely to use all substances at friends' homes and on weekends; to smoke cigarettes at school, in the car, and on weeknights; and to use alcohol at home. Black adolescents were more likely to report using alcohol at home, at school, in cars, during and after school, and on weeknights and were more likely to report using marijuana at school. The location and time of adolescent substance use vary substantially by age, gender, and race. These differences may help tailor substance use prevention and intervention programs to specific subgroups of youth to improve program effectiveness.

    The six-minute walk test (6 WT) is a valid and reliable predictor of morbidity and mortality in chronic heart failure (CHF) patients, frequently used as an endpoint or target in clinical trials. As opposed to spiroergometry, improvement of its prognostic accuracy by correction for height, weight, age and gender has not yet been attempted comprehensively despite known influences of these parameters. We recorded the 6 WT of 1035 CHF patients, attending clinic from 1995 to 2005. The 1-year prognostic value of 6 WT was calculated, alone and after correction for height, weight, BMI and/or age. Analysis was performed on the entire cohort, on males and females separately and stratified according to BMI (30 kg/m(2)). 6 WT weakly correlated with age (r=-0.32; p<0.0001), height (r=0.2; p<0.0001), weight (r=0.11; p<0.001), not with BMI (r=0.01; p=ns). The 6 WT was a strong predictor of 1-year mortality in both genders, both as a single and age corrected parameter. Parameters derived from correction of 6 WT for height, weight or BMI did not improve the prognostic value in univariate analysis for either gender. Comparison of the receiver operated characteristics showed no significant gain in prognostic accuracy from any derived variable, either for males or females. The six-minute walk test is a valid tool for risk prediction in both male and female CHF patients. In both genders, correcting 6 WT distance for height, weight or BMI alone, or adjusting for age, does not increase the prognostic power of this tool.

    2013-03-01

    Full Text Available The research goal is to study probability, period of development and characteristics of a clinical course of chronic prostatitis against the background of androgen deficiency in the aging male. Materials and methods: The Aging Male Symptoms (AMS rating scale has been applied for androgen deficiency evaluation and the International Prostate Symptom Score (IPSS — for chronic prostatitis evaluation. 57 men with chronic prostatitis in combination with androgen deficiency in the aging male have been examined. Results: It has been concluded that the development of chronic prostatitis against the background of androgen deficiency in the aging male occurs in a shorter time period and about 1.5 times more frequently compared to androgen deficiency in the aging male at the background of chronic prostatitis. The analysis of time periods between the onset of chronic prostatitis symptoms against the background of androgen deficiency in the aging male and androgen deficiency in the aging male symptoms against the background of chronic prostatitis showed that androgen deficiency in the aging male symptoms have been revealed 1-2 years earlier than the onset of chronic prostatitis. The development of androgen deficiency in the aging male against the background of chronic prostatitis has showed a backward tendency. Signs of chronic prostatitis have been more frequently occurred in a period of four-five years earlier the androgen deficiency in the aging male development. Conclusion: The risk of development of chronic prostatitis against the background of androgen deficiency in the aging male during the next two years is actually four times higher in comparison with the development of androgen deficiency in the aging male against the background of chronic prostatitis. According to the International Prostate Symptom Score (IPSS, patients with chronic prostatitis in combination with androgen deficiency in the aging male showed higher degree of severity than

  8. Breaking Away From the Male Stereotype of a Specialist: Gendered Language Affects Performance in a Thinking Task

    Marlene Kollmayer

    2018-06-01

    Full Text Available This experimental online-survey study investigated if different written language forms in German have an effect on male bias in thinking. We used answers to the specialist riddle as an indicator for male bias in mental representations of expertise. The difficulty of this thinking task lies in the fact that a gender-unspecified specialist is often automatically assumed to be a man due to gender stereotypes. We expected that reading a text in gender-fair language before processing the specialist riddle helps readers achieve control over automatically activated gender stereotypes and thus facilitates the restructuring and reinterpretation of the problem, which is necessary to reach the conclusion that the specialist is a woman. We randomly assigned 517 native German speakers (68% women to reading a text on expertise written either in gender-fair language or in masculine generics. Subsequently, participants were asked to solve the specialist riddle. The results show that reading a text in gender-fair language before processing the riddle led to higher rates of answers indicating that the specialist is a women compared to reading a text in masculine generics (44% vs. 33% in women and men regardless of their self-stereotyping concerning agency and communion. The findings indicate that reading even a very short text in gender-fair language can help people break their gender-stereotype habit and thus reduce male bias in thinking. Our research emphasizes the importance of using gender-fair language in German-language texts for reducing gender stereotypes.

  9. Age identity, gender, and perceptions of decline: does feeling older lead to pessimistic dispositions about cognitive aging?

    Schafer, Markus H; Shippee, Tetyana P

    2010-01-01

    Drawing on past studies of age identity, this article examined whether feeling older was associated with more pessimistic views about cognitive aging. Using respondents aged 55 years and older in the Midlife Development in the United States study, we estimated a series of linear regression models to predict people's dispositions toward their cognitive aging. The main comparison is whether the effects of age identity on cognitive aging differ for men and women. Beyond the effects of chronological age, older age identities were associated with more pessimistic dispositions about cognitive aging. This relationship, however, was found only among women. Age identity shapes cognitive aging dispositions, though the gendered nature of this relationship remains somewhat unclear. The findings give further evidence about the far-reaching implications of age identity for successful aging and suggest that future work can explicate how subjective aging processes may differ by gender.

  10. Will you still need me, will you still feed me? Old-age pensions in Iceland from a gender perspective

    Steinunn Rögnvaldsdóttir

    2012-12-01

    Full Text Available Icelandic women have through the years earned less occupational and supplemental pensions and depended more than men do on the basic pension of social security. Although women’s labour market participation has increased, the gender pay gap, unpaid labour in homes, and women’s fewer working hours in paid labour results in the extension of the labour market gender discrimination into old age. The structure of Icelandic pension funds is fundamentally male biased because of its tight connection to employment, despite the absence of direct discrimination factors. The article provides an overview of implications for a more women friendly pension system; based on multi-national research; the analysis of the Icelandic pension system, and statistical information on older women and men’s economic situation in Iceland. Adequate basic pension, elimination of labour market gender discrimination, and males taking greater responsibility for care- and housework, are some of the key issues in creating a more gender equal pension system. Sharing of pensions between spouses, the responsibility of pension-funds and companies, and possibilities of care credit systems to promote gender equality are also discussed.

  11. Behavioural and cognitive sex/gender differences in autism spectrum condition and typically developing males and females.

    Hull, Laura; Mandy, William; Petrides, K V

    2017-08-01

    Studies assessing sex/gender differences in autism spectrum conditions often fail to include typically developing control groups. It is, therefore, unclear whether observed sex/gender differences reflect those found in the general population or are particular to autism spectrum conditions. A systematic search identified articles comparing behavioural and cognitive characteristics in males and females with and without an autism spectrum condition diagnosis. A total of 13 studies were included in meta-analyses of sex/gender differences in core autism spectrum condition symptoms (social/communication impairments and restricted/repetitive behaviours and interests) and intelligence quotient. A total of 20 studies were included in a qualitative review of sex/gender differences in additional autism spectrum condition symptoms. For core traits and intelligence quotient, sex/gender differences were comparable in autism spectrum conditions and typical samples. Some additional autism spectrum condition symptoms displayed different patterns of sex/gender differences in autism spectrum conditions and typically developing groups, including measures of executive function, empathising and systemising traits, internalising and externalising problems and play behaviours. Individuals with autism spectrum conditions display typical sex/gender differences in core autism spectrum condition traits, suggesting that diagnostic criteria based on these symptoms should take into account typical sex/gender differences. However, awareness of associated autism spectrum condition symptoms should include the possibility of different male and female phenotypes, to ensure those who do not fit the 'typical' autism spectrum condition presentation are not missed.

  12. Parent-Child Positive Touch: Gender, Age, and Task Differences.

    Aznar, Ana; Tenenbaum, Harriet R

    2016-01-01

    This study examined gender, age, and task differences in positive touch and physical proximity during mother-child and father-child conversations. Sixty-five Spanish mothers and fathers and their 4- ( M  = 53.50 months, SD  = 3.54) and 6-year-old ( M  = 77.07 months, SD  = 3.94) children participated in this study. Positive touch was examined during a play-related storytelling task and a reminiscence task (conversation about past emotions). Fathers touched their children positively more frequently during the play-related storytelling task than did mothers. Both mothers and fathers were in closer proximity to their 6-year-olds than their 4-year-olds. Mothers and fathers touched their children positively more frequently when reminiscing than when playing. Finally, 6-year-olds remained closer to their parents than did 4-year-olds. Implications of these findings for future research on children's socioemotional development are discussed.

  13. Primary Teachers and ICT: Is gender, age or experience important?

    Graham Morley

    2011-12-01

    Full Text Available The research uses both qualitative and quantitative methodologies employing multiple sources of data collection. The data collection primarily used a questionnaire survey of primary schools in two English Local Authorities. The qualitative evidence of the teacher sample was through individual semi-structured interviews and a focus group interview of Local Authorities officers. There is an evidence trail which examines academic papers, HMI, QCA, Ofsted and DfES reports. The main findings from these reports indicate that teachers were becoming familiar with the use of computers. They understood the skills involved in using computers but were still uncertain as to a suitable pedagogy which made them lack confidence when using ICT in the classroom. Teachers’ major difficulty is finding time to keep pace or develop their ICT skills. The reports have a generic view of teachers, with no further analysis of gender, age or experience phenomena. The analysis of these variables concludes that teacher subject knowledge formed through teaching experience of the subject, informs teachers when computers aid teaching and learning.

  14. Male-typical visuospatial functioning in gynephilic girls with gender dysphoria — organizational and activational effects of testosterone

    Burke, Sarah M.; Kreukels, Baudewijntje P.C.; Cohen-Kettenis, Peggy T.; Veltman, Dick J.; Klink, Daniel T.; Bakker, Julie

    2016-01-01

    Background Sex differences in performance and regional brain activity during mental rotation have been reported repeatedly and reflect organizational and activational effects of sex hormones. We investigated whether adolescent girls with gender dysphoria (GD), before and after 10 months of testosterone treatment, showed male-typical brain activity during a mental rotation task (MRT). Methods Girls with GD underwent fMRI while performing the MRT twice: when receiving medication to suppress their endogenous sex hormones before onset of testosterone treatment, and 10 months later during testosterone treatment. Two age-matched control groups participated twice as well. Results We included 21 girls with GD, 20 male controls and 21 female controls in our study. In the absence of any group differences in performance, control girls showed significantly increased activation in frontal brain areas compared with control boys (pFWE = 0.012). Girls with GD before testosterone treatment differed significantly in frontal brain activation from the control girls (pFWE = 0.034), suggesting a masculinization of brain structures associated with visuospatial cognitive functions. After 10 months of testosterone treatment, girls with GD, similar to the control boys, showed increases in brain activation in areas implicated in mental rotation. Limitations Since all girls with GD identified as gynephilic, their resemblance in spatial cognition with the control boys, who were also gynephilic, may have been related to their shared sexual orientation rather than their shared gender identity. We did not account for menstrual cycle phase or contraceptive use in our analyses. Conclusion Our findings suggest atypical sexual differentiation of the brain in natal girls with GD and provide new evidence for organizational and activational effects of testosterone on visuospatial cognitive functioning.

    Objective: Using clinical "big data" , to investigate the factors that affect the levels of thyroid hormones, and to explore the partitioning criteria for reference intervals (RI) of these hormones. Methods: An observation study was conducted. Information of 107 107 individuals undergoing routine physical examination in Peking Union Medical College Hospital from September 1(st,) 2013 to August 31(st,) 2016 was collected, thyroid hormone of these subjects were detected. To explore the test results distribution and differences of TSH, FT4 and FT3 by gender and age; according to the seasonal division standard of China Meteorological Administration, the study period was divided into four seasons, and the seasonal fluctuation on TSH was analyzed.To define the appropriate partition by gender, age and season according to significant difference analysis. Results: In male and female, the distributions of TSH were 1.779(0.578-4.758), 2.023(0.420-5.343)mU/L, respectively, and the level of TSH in female was higher than in male ( Z =-37.600, P groups by 65 years old and female were divided by 50 years old, respectively, and the distributions of TSH in male and female of older group were 1.818(0.528-5.240), 2.111(0.348-5.735)mU/L, in younger group were 1.778(0.582-4.696), 1.991(0.427-5.316)mU/L. The level of TSH in older group was significantly higher than in younger group ( Z =-2.269, -10.400, all P group was much wider than in younger. The distribution of whole in spring, summer and autumn was 1.869( 0.510-5.042)mU/L, in winter was 1.978(0.527-5.250) mU/L, and the difference between them had statistical significance ( Z =-15.000, P age significantly affect the serum levels of TSH, FT4, and FT3, the distribution of TSH in female and elder group are wider than in male, and that of FT4, FT3 are lower.Seasons significantly affect the serum TSH level, the peak value is observed in winter. There are obviously differences between "rough" RIs and manufacture recommended RIs. Each

  17. The impact of male migration from Morocco to Europe on women: a gender approach

    Fatima Sadiqi

    2004-06-01

    Full Text Available This paper offers a gender approach to the impact of male migrationfrom Morocco to Europe on women left behind. The pertinence of the topic stems from the fact that very few studies have been conducted on the subject. It is believed that such studies will help in the understanding of the the phenomenon of migration and help to find solutions for some of the problems it poses. More and more Moroccan women suffer as a result of the migration of their husbands, sons,fathers, etc. Their suffering is not only due to separation from the loved ones but also to the dire economic and social conditions that a heavily patriarchal context does not help to alleviate.

  18. Influence of Japanese consumer gender and age on sensory attributes and preference (a case study on deep-fried peanuts).

    Miyagi, Atsushi

    2017-09-01

    Detailed exploration of sensory perception as well as preference across gender and age for a certain food is very useful for developing a vendible food commodity related to physiological and psychological motivation for food preference. Sensory tests including color, sweetness, bitterness, fried peanut aroma, textural preference and overall liking of deep-fried peanuts with varying frying time (2, 4, 6, 9, 12 and 15 min) at 150 °C were carried out using 417 healthy Japanese consumers. To determine the influence of gender and age on sensory evaluation, systematic statistical analysis including one-way analysis of variance, polynomial regression analysis and multiple regression analysis was conducted using the collected data. The results indicated that females were more sensitive to bitterness than males. This may affect sensory preference; female subjects favored peanuts prepared with a shorter frying time more than male subjects did. With advancing age, textural preference played a more important role in overall preference. Older subjects liked deeper-fried peanuts, which are more brittle, more than younger subjects did. In the present study, systematic statistical analysis based on collected sensory evaluation data using deep-fried peanuts was conducted and the tendency of sensory perception and preference across gender and age was clarified. These results may be useful for engineering optimal strategies to target specific segments to gain greater acceptance in the market. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

  19. Implementation of age and gender recognition system for intelligent digital signage

    Lee, Sang-Heon; Sohn, Myoung-Kyu; Kim, Hyunduk

    2015-12-01

    Intelligent digital signage systems transmit customized advertising and information by analyzing users and customers, unlike existing system that presented advertising in the form of broadcast without regard to type of customers. Currently, development of intelligent digital signage system has been pushed forward vigorously. In this study, we designed a system capable of analyzing gender and age of customers based on image obtained from camera, although there are many different methods for analyzing customers. We conducted age and gender recognition experiments using public database. The age/gender recognition experiments were performed through histogram matching method by extracting Local binary patterns (LBP) features after facial area on input image was normalized. The results of experiment showed that gender recognition rate was as high as approximately 97% on average. Age recognition was conducted based on categorization into 5 age classes. Age recognition rates for women and men were about 67% and 68%, respectively when that conducted separately for different gender.

  20. Mating choice of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae): influence of male ageing on mating success

    Silva Neto, Alberto M. da; Dias, Vanessa S.; Joachim-Bravo, Iara S.

    2009-01-01

    The objective of this study was to evaluate the effect of male ageing on male pheromone release and mating success of Ceratitis capitata (Wiedemann). The effects of male ageing on mating were evaluated on fi ve and 21 d-old males by assessing their mating success (males chosen by a female for copulation) and the amount of males releasing the sex pheromone. The mating success was evaluated by using several ratios of young to older males by increasing the number of older males:young males from 1:1 to 5:1. The mating success of the 1:1 ratio was also evaluated in fi eld cages. The evaluation of the mating success (in the 1:1 ratio) showed a clear preference of the females for young males. Sex pheromone emission was much more common on young than older males. Even in cases were older males were more abundant (ratios 2:1 and 3:1), females still chose the young males. However, females could not distinguish young from older males in ratios of 4:1 or 5:1. Our data indicate that the ageing of C. capitata males has a considerable negative effect on their reproductive success, especially if they are found in a proportion any lower than 3:1. (author)

  1. The experiences of male sudden cardiac arrest survivors and their partners: a gender analysis.

    Uren, Alan; Galdas, Paul

    2015-02-01

    To explore how masculinities shape the experiences of men and their partners after survival from out-of-hospital cardiac arrest. Survivors of out-of-hospital cardiac arrest report depression, dependence on others for daily functioning, decreased participation in society and significant decreases in quality of life. There is growing evidence that masculine gender identities play a central role in the recovery experiences of men and their families following other major cardiac events. However, to date, there has been no examination of how masculinities shape men's experiences of recovery following out-of-hospital cardiac arrest. Interview study guided by an interpretive description approach. Data were subjected to thematic analysis. A purposive sample of seven male sudden cardiac arrest survivors and 6 female partners was recruited in 2010 from a secondary care centre in British Columbia, Canada. Three themes were prominent in the experiences of the participants: (1) Support and self-reliance; (2) Dealing with emotional (in) vulnerability; and (3) No longer a 'He-man'. Masculinities played a role in men's experiences of recovery and adaptation following out-of-hospital cardiac arrest. Hegemonic masculinity partly explained men's experiences, notably their reluctance to seek professional support and reactions to changes in lifestyle. However, the study also suggests that the popular stereotype of men being 'strong and silent' in the face of ill-health may only be a part of a more complex story. Nurses would benefit from taking into consideration the potential influence of male gender identities on men's recovery postcardiac arrest. © 2014 John Wiley & Sons Ltd.

  3. Age and gender influence on oral hygiene among adolescents with fixed orthodontic appliances.

    Kudirkaite, Ieva; Lopatiene, Kristina; Zubiene, Jurate; Saldunaite, Kristina

    2016-01-01

    Many factors can influence oral health including oral hygiene measures, eating habits, attention from parents, education and the social situation. It is even harder to keep good oral health when orthodontic treatments are applied, because orthodontic treatments are usually undergone by children and adolescents who have fewer skills and pay less attention to their oral health; this may lead to bleeding on probing (BOP), a higher plaque index (PI), a higher gingival index (GI), and an increase in probing pocket depth (PPD). The aim of this study was to compare the features of oral hygiene among different age groups and gender in patients with fixed orthodontic appliances. The study consisted of 107 patients from the Department of Orthodontics of Lithuanian University of Health Sciences aged 12 to 18 years with fixed orthodontic appliances. The patients were given a questionnaire with 17 questions about their oral hygiene and how it changed after they started their treatment with fixed orthodontic appliances. A statistical analysis was performed using the IBM SPSS Statistics 22.0. Among the 107 participants, 69 (64.5%) were females and 38 (35.5%) were males. 57 (53.3%) participants were 12 to 15 years old and 50 (46.7%) 16 to 18 years old. There was a statistically significant result when comparing the differences between females and males: females brushed their teeth more regularly than males (pappliances, the oral hygiene of 16 to 18 year old adolescents is better than the oral hygiene of 12 to 15 year old adolescents. Females brush their teeth more regularly than males. More studies should be done to evaluate any differences.

    2017-08-01

    Although an interaction between gender and age has been shown to influence resuscitation outcomes in patients with out-of-hospital cardiac arrest (OHCA), this interaction has not been investigated in Asian populations. In this prospective, observational study, data from all cases of OHCA in Japan between 2005 and 2012 were obtained from the Japanese National Registry. We determined the relative excess risk due to interaction and the ratio of odds ratios (ORs) to assess the interaction effect of gender and age on the incidence of return of spontaneous circulation (ROSC) before hospital arrival, 1-month survival, and neurologically intact survival 1 month after OHCA. Male gender was associated with decreased ROSC and lower 1-month survival rates in patients with OHCA of presumed cardiac origin. Older age was associated with lower 1-month and neurologically intact survival rates in male patients with OHCA of presumed cardiac and noncardiac origin and with increased ROSC in male patients with OHCA of presumed cardiac origin. The relative excess risk due to interaction for ROSC in patients with OHCA of presumed cardiac origin was statistically significant (OR 0.19, 95% confidence interval [CI] 0.06 to 0.32). The ratio of ORs for ROSC was statistically significant in patients with OHCA of presumed cardiac origin (OR 1.25, 95% CI 1.05 to 1.47) and of noncardiac origin (OR 0.40, 95% CI 0.17 to 0.92). In conclusion, the interaction effect between age and gender on ROSC was positive in OHCA cases of presumed cardiac origin and negative in those of noncardiac origin. Copyright © 2017 Elsevier Inc.

  5. Adolescent Self-Esteem: Differences by Race/Ethnicity, Gender, and Age

    Bachman, Jerald G.; O’Malley, Patrick M.; Freedman-Doan, Peter; Trzesniewski, Kali H.; Donnellan, M. Brent

    2012-01-01

    Large-scale representative surveys of 8th-, 10th-, and 12th-grade students in the United States show high self-esteem scores for all groups. African-American students score highest, Whites score slightly higher than Hispanics, and Asian Americans score lowest. Males score slightly higher than females. Multivariate controls for grades and college plans actually heighten these race/ethnic/gender differences. A truncated scoring method, designed to counter race/ethnic differences in extreme response style, reduced but did not eliminate the subgroup differences. Age differences in self-esteem are modest, with 12th graders reporting the highest scores. The findings are highly consistent across 18 annual surveys from 1991 through 2008, and self-esteem scores show little overall change during that period. PMID:22279425

  7. GENDER-BASED DIFFERENCES IN SCHOOL-AGED CHILDREN’S DIVERGENT THINKING

    Leah Roue

    2014-12-01

    Full Text Available This study examines whether the shortage of females in science and engineering is linked to possible gender-based differences in school-aged children’s divergent thinking. Divergent thinking is a direct measure of creativity and an important characteristic in science and engineering. A survey instrument designed to measure divergent thinking was administered to 8th and 11th graders in a mid-western United States school district. Results showed that there were no difference between girls and boys on the three measures of divergent thinking: fluency, flexibility, and originality. These results indicate little reason as to why participation in science and engineering is male dominated, and support the notion that additional exposure to science and engineering through divergent-thinking activities will provide girls with the self-knowledge that they are capable of solving open-ended problems and engineering tasks.

    2013-07-01

    Full Text Available Gender issues in the field of education has been a continuos debated issue for generations. In the present context, the gender issue is being debated heatedly based on the differences in the achievements among male and female students in public exams.The objective of this study is to obtain views from (N=120 secondary school students randomly selected from various location in Malaysia. Hermeneutic analysis was used in order to analyse the students’ written essays on the factors which contributed to the achievement of the two genders in examinations. The findings of the study clearly indicated that female students outperform male students in examinations. The sample also summed up the factors leading to the failure of male students in performing well and ways to overcome this setback.

    The prognostic value of gender and age in the survival of nasopharyngeal carcinoma (NPC) patients treated with intensity-modulated radiotherapy (IMRT) is unclear. Several studies have suggested a female advantage in the prognosis of solid tumors. We investigated the relationship between gender differences and disease outcome in NPC patients treated with IMRT in South China. A total of 299 patients with non-disseminated NPC were analyzed retrospectively. IMRT was delivered with a simultaneous modulated, accelerated radiotherapy boost technique at prescribed doses of 70 Gy/30 fractions/6 weeks to the primary tumor (GTVp) and positive neck nodes (GTVn), 60Gy (2.0 Gy/day) to the clinical target volume (CTV) and upper neck region and 54 Gy (1.8 Gy/day) to the clinically negative low neck. A median boost dose of 9.2 Gy (4–20 Gy) was administered to patients with persistent disease at the primary site. With a median follow-up of 52 months, the male patients had a significantly unfavorable 5-year OS (70.7% compared to 94.1%, P < 0.001), DPFS (71.5% compared to 87.3%, P = 0.029) and DMFS (77.2% compared to 89.7%, P = 0.036) than the female patients. In patients younger than 45, the male patients had a poorer 5-year OS (66.8% compared to 91.2%, P = 0.008), DPFS (59.9% compared to 91.2%, P = 0.005) and DMFS (66.4% compared to 94.0%, P = 0.004) than the female patients. For patients older than 45, only the 5-year OS (72.2% compared to 96.0%, P = 0.001) was significantly different. Gender and age are strong independent prognostic factors for NPC in this study. We are the first to report that younger male patients were more likely to have distant metastases and exhibited inferior overall survival and disease progression-free survival rates compared to other patients

  10. Behavioural and cognitive sex/gender differences in autism spectrum condition and typically developing males and females

    Hull, L.; Mandy, W.; Petrides, K.

    2017-01-01

    Studies assessing sex/gender differences in autism spectrum conditions often fail to include typically developing control groups. It is, therefore, unclear whether observed sex/gender differences reflect those found in the general population or are particular to autism spectrum conditions. A systematic search identified articles comparing behavioural and cognitive characteristics in males and females with and without an autism spectrum condition diagnosis. A total of 13 studies were included ...

  11. Age and gender differences in the relation between self-concept facets and self-esteem

    Arens, A. Katrin; Hasselhorn, Marcus

    2014-01-01

    This study tested whether the gender intensification hypothesis applies to relations between multiple domain-specific self-concept facets and self-esteem. This hypothesis predicts gender-stereotypic differences in these relations and assumes they intensify with age. Furthermore, knowledge about gender-related or age-related differences in self-concept-self-esteem relations might provide valuable knowledge for designing effective self-esteem enhancement interventions. We investigated grade and...

  12. Fertility Decline, Gender Composition of Families, and Expectations of Old Age Support

    Allendorf, Keera

    2014-01-01

    Recent fertility declines in non-Western countries may have the potential to transform gender systems. One pathway for such transformations is the creation of substantial proportions of families with children of only one gender. Such families, particularly those with only daughters, may facilitate greater symmetry between sons and daughters. This article explores whether such shifts may influence gendered expectations of old age support. In keeping with patriarchal family systems, old age sup...

  13. Age-dependent male mating tactics in a spider mite-A life-history perspective.

    2016-10-01

    Males often fight with rival males for access to females. However, some males display nonfighting tactics such as sneaking, satellite behavior, or female mimicking. When these mating tactics comprise a conditional strategy, they are often thought to be explained by resource holding potential (RHP), that is, nonfighting tactics are displayed by less competitive males who are more likely to lose a fight. The alternative mating tactics, however, can also be explained by life-history theory, which predicts that young males avoid fighting, regardless of their RHP, if it pays off to wait for future reproduction. Here, we test whether the sneaking tactic displayed by young males of the two-spotted spider mite can be explained by life-history theory. We tested whether young sneaker males survive longer than young fighter males after a bout of mild or strong competition with old fighter males. We also investigated whether old males have a more protective outer skin-a possible proxy for RHP-by measuring cuticle hardness and elasticity using nanoindentation. We found that young sneaker males survived longer than young fighter males after mild male competition. This difference was not found after strong male competition, which suggests that induction of sneaking tactic is affected by male density. Hardness and elasticity of the skin did not vary with male age. Given that earlier work could also not detect morphometric differences between fighter and sneaker males, we conclude that there is no apparent increase in RHP with age in the mite and age-dependent male mating tactics in the mite can be explained only by life-history theory. Because it is likely that fighting incurs a survival cost, age-dependent alternative mating tactics may be explained by life-history theory in many species when reproduction of old males is a significant factor in fitness.

  14. The MCCB impairment profile in a Spanish sample of patients with schizophrenia: Effects of diagnosis, age, and gender on cognitive functioning.

    Rodriguez-Jimenez, R; Dompablo, M; Bagney, A; Santabárbara, J; Aparicio, A I; Torio, I; Moreno-Ortega, M; Lopez-Anton, R; Lobo, A; Kern, R S; Green, M F; Jimenez-Arriero, M A; Santos, J L; Nuechterlein, K H; Palomo, T

    2015-12-01

    The MATRICS Consensus Cognitive Battery (MCCB) was administered to 293 schizophrenia outpatients and 210 community residents in Spain. Our first objective was to identify the age- and gender-corrected MCCB cognitive profile of patients with schizophrenia. The profile of schizophrenia patients showed deficits when compared to controls across the seven MCCB domains. Reasoning and Problem Solving and Social Cognition were the least impaired, while Visual Learning and Verbal Learning showed the greatest deficits. Our second objective was to study the effects on cognitive functioning of age and gender, in addition to diagnosis. Diagnosis was found to have the greatest effect on cognition (Cohen's d>0.8 for all MCCB domains); age and gender also had effects on cognitive functioning, although to a lesser degree (with age usually having slightly larger effects than gender). The effects of age were apparent in all domains (with better performance in younger subjects), except for Social Cognition. Gender had effects on Attention/Vigilance, Working Memory, Reasoning and Problem Solving (better performance in males), and Social Cognition (better performance in females). No interaction effects were found between diagnosis and age, or between diagnosis and gender. This lack of interactions suggests that age and gender effects are not different in patients and controls. Copyright © 2015 Elsevier B.V. All rights reserved.

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

  17. Gender differences and the definition of success: male and female veterinary students' career and work performance expectations.

    Kogan, Lori R; McConnell, Sherry L; Schoenfeld-Tacher, Regina

    2004-01-01

    This article addresses the challenges that gender performance expectations create within the veterinary profession. An investigation of veterinary students' perceptions of the essential characteristics that define successful veterinarians and veterinary students, and the gender differences within these definitions, is described. Because previous research supports the premise that the standards required for success differ for males and females, it is likely that male and female veterinary students possess different career expectations and definitions of career success. The ramifications of these differences are explored, and proposed strategies to address this issue, in the form of student support services, are discussed.

  18. Assessment of peritrochanteric high T2 signal depending on the age and gender of the patients

    2010-07-15

    Introduction: The aim of this study is to evaluate the incidence of peritrochanteric high T2 signal (peritrochanteric edema, peritendinitis) on routine MR imaging studies and to determine whether reporting peritrochanteric edema is always clinically relevant depending on the age and gender of the patients. Materials and methods: We evaluated 79 consecutive bilateral hip MR images performed in our department between January 2006 and December 2006 (57 female, 22 male patients, mean age 49 years). Each study was evaluated for areas of T2 hyperintensity representing edema around the greater trochanter. Patients with a known fracture, tumor, history of radiation therapy, history of hip surgery and prothesis were excluded from the study. Patients with signal intensity alterations within the thickened gluteus medius/minimus tendons (tendinitis) or peritrochanteric bursal fluid accumulation (bursitis) were also excluded. All patients were scanned with our routine MR imaging protocol for hip imaging. Results: In 55 of the 79 patients (70%) peritrochanteric edema was detected on MR images and 52 of these 55 patients (95%) had these changes on both hips. The median age was 56 years for the patients with peritrochanteric edema and 35.5 years for the patients without peritrochanteric edema. There was statistical significance between the median ages of the patients and a significant increased risk of peritrochanteric edema was found over 40 years of age. There was no significant difference between male and female patients. Conclusion: Bilateral peritrochanteric high T2 signal may be a part of the degeneration process and we suggest that it may not be necessarily reported if the clinical findings do not support greater trochanteric pain syndrome.

  20. Effects of male sex hormones on gender identity, sexual behavior, and cognitive function.

    Zhu, Yuan-shan; Cai, Li-qun

    2006-04-01

    Androgens, the male sex hormones, play an essential role in male sexual differentiation and development. However, the influence of these sex hormones extends beyond their roles in sexual differentiation and development. In many animal species, sex hormones have been shown to be essential for sexual differentiation of the brain during development and for maintaining sexually dimorphic behavior throughout life. The principals of sex determination in humans have been demonstrated to be similar to other mammals. However, the hormonal influence on sexual dimorphic differences in the nervous system in humans, sex differences in behaviors, and its correlations with those of other mammals is still an emerging field. In this review, the roles of androgens in gender and cognitive function are discussed with the emphasis on subjects with androgen action defects including complete androgen insensitivity due to androgen receptor mutations and 5alpha-reductase-2 deficiency syndromes due to 5alpha-reductase-2 gene mutations. The issue of the complex interaction of nature versus nurture is addressed.

    2010-02-01

    This study was conducted to analyze how male sexual offenders construct mental images of masculinity and femininity to provide insight into therapeutic treatment for such patients. Thematerial examined in this studywas comprised of 21 videotaped prison group therapy sessions in which the participating sexual offenders talked about their crimes and biographies. Aqualitative data analysis softwarewas usedto apply a modified grounded theorymethodology to the transcribed sessions. The resulting categories can be understood as descriptions of how the imprisoned men constructed gender images, and were based on three narrative levels: the structure of narration, the narrative positions in the story, and the interaction between the narrator and the other participants. According to the categories describedin the narrative positions (the narrated self and the narrated significant male others), we constructed masculinity categorizations which corresponded to specific images of femininity (derived from the narrated significant female others).The constructionsprovided insight into the selfimage of the narrator, as well as the accountability and positioning of himself and the other in regard to perpetrator-victim constructions. The study further revealed whether the participants either accepted or rejected responsibility and guilt for their crimes; this is essential for psychotherapeutic process and treatment.

    In most cases, about the voice of the patient with female-to-male/gender identity disorder (FTM/GID), hormone therapy makes the voice low-pitched. In success cases, there is no need for phonosurgery. However, hormone therapy is not effective in some cases. We perform type 3 thyroplasty in these cases. Hormone therapy was started in 2008 but did not lower the speaking fundamental frequencies (SFFs). We therefore performed TP3 under local anesthesia. In our case, the SFF at the first visit was 146 Hz. The postoperative SFF was 110 Hz. TP3 was performed under local anesthesia in a patient with FTM/GID in whom hormone therapy proved ineffective. With successful conversion to a lower-pitched voice, the patient could begin to live daily life as a male. QOL improved significantly with TP3. If hormone therapy proves ineffective, TP3 may be selected as an optional treatment and appears to show few surgical complications and was, in this case, a very effective treatment.

    2015-01-01

    Male intensive care unit (ICU) nurses bring energy and expertise along with an array of beliefs and practices to their workplace. This article investigates the experiences of male ICU nurses in the context of caring for dying patients and their families. Applying a gender analysis, distilled are insights to how masculinities inform and influence the participants' practices and coping strategies. The findings reveal participants draw on masculine ideals of being a protector and rational in their decisive actions toward meeting the comfort needs of dying patients and their families. Somewhat paradoxically, most participants also transgressed masculine norms by outwardly expressing their feelings and talking about emotions related to these experiences. Participants also reported renewed appreciation of their life and their families and many men chronicled recreational activities and social connectedness as strategies for coping with workplace induced stresses. The findings drawn from this study can guide both formal and informal support services for men who are ICU nurses, which in turn might aid retention of this subgroup of workers. © The Author(s) 2014.

  5. Noninvasive markers of bone metabolism in the rhesus monkey: normal effects of age and gender

    Cahoon, S.; Boden, S. D.; Gould, K. G.; Vailas, A. C.

    1996-01-01

    Measurement of bone turnover in conditions such as osteoporosis has been limited by the need for invasive iliac bone biopsy to reliably determine parameters of bone metabolism. Recent advances in the area of serum and urinary markers of bone metabolism have raised the possibility for noninvasive measurements; however, little nonhuman primate data exist for these parameters. The purpose of this experiment was to define the normal range and variability of several of the newer noninvasive bone markers which are currently under investigation in humans. The primary intent was to determine age and gender variability, as well as provide some normative data for future experiments in nonhuman primates. Twenty-four rhesus macaques were divided into equal groups of male and female according to the following age groupings: 3 years, 5-10 years, 15-20 years, and > 25 years. Urine was collected three times daily for a four-day period and measured for several markers of bone turnoverm including pyridinoline (PYD), deoxypyrodinoline (DPD), hydroxyproline, and creatinine. Bone mineral density measurements of the lumbar spine were performed at the beginning and end of the study period. Serum was also obtained at the time of bone densitometry for measurement of osteocalcin levels by radioimmunoassay. There were no significant differences in bone mineral density, urine PYD, or urine DPD based on gender. Bone density was lowest in the youngest animals, peaked in the 15-20-year group, but again decreased in the oldest animals. The osteocalcin, PYD, and DPD levels followed an inversely related pattern to bone density. The most important result was the relative age insensitivity of the ratio of PYD:DPD in monkeys up to age 20 years. Since bone density changes take months or years to become measurable and iliac biopsies are invasive, the PYD/DPD marker ratio may have important implications for rapid noninvasive measurement of the effects of potential treatments for osteoporosis in the non

    2006-07-01

    Full Text Available Abstract Background Release of genetically-modified (GM or sterile male mosquitoes for malaria control is hampered by inability to assess the age and mating history of free-living male Anopheles. Methods Age and mating-related changes in the reproductive system of male Anopheles gambiae were quantified and used to fit predictive statistical models. These models, based on numbers of spermatocysts, relative size of sperm reservoir and presence/absence of a clear area around the accessory gland, were evaluated using an independent sample of mosquitoes whose status was blinded during the experiment. Results The number of spermatocysts in male testes decreased with age, and the relative size of their sperm reservoir increased. The presence of a clear area around accessory glands was also linked to age and mating status. A quantitative model was able to categorize males from the blind trial into age groups of young (≤ 4 days and old (> 4 days with an overall efficiency of 89%. Using the parameters of this model, a simple table was compiled that can be used to predict male age. In contrast, mating history could not be reliably assessed as virgins could not be distinguished from mated males. Conclusion Simple assessment of a few morphological traits which are easily collected in the field allows accurate age-grading of male An. gambiae. This simple, yet robust, model enables evaluation of demographic patterns and mortality in wild and released males in populations targeted by GM or sterile male-based control programmes.

    To define the dimensions of the frontal sinus in groups standardized for age and gender and to discuss the reasons and the effects of the variations. Methods: Frontal sinus measurements were obtained from paranasal CTscans of 180 males and 180 females in the Radiology Department of Dursun Odabas Medical Center of Yuzuncu Yil University, Van, which is located in Eastern Turkey, between February and March 2016. The width and height of sinuses were measured on a coronal plane, and the anteroposterior length was measured on an axial plane. Volumes were calculated using the Hospital Information Management Systems and Image Archiving and Management Systemprogram. The Statistical Package of the Social Science version 13 was used for statistical analyses.  Results: We determined differences in the frontal sinus measurements of different age groups in a Turkish adult population. Frontal sinus dimensions were usually higher in females and lower in males after 40-49 years of age than their younger counterparts, but the measurements were lower in females and higher in males in 70≤ years of age group than 60-69 years of age. Left frontal sinus was dominant in young age groups but right frontal sinus was dominant in groups 40-49 years of age or older.  Conclusion: We observed crossing of the measurements between the different age groups, which we could not find clear explanations. The results of such studies may affect forensic identification from frontal sinus measurements.

    2012-12-01

    The primary objective of this study was to explore gender and age differences in the use of medical services during the year preceding suicide. Data were obtained from the mortality dataset of Department of Health and National Health Insurance Database. Included in the sample were 862 persons aged 12-24 years who committed suicide in Taiwan between 2001 and 2004. We compared the records of medical service utilization of adolescents (ages 12-18 years) with young adults (ages 19-24 years). Persons in both age groups contacted general practitioners more often than other types of medical providers in the year preceding suicide, with the exception of the month before suicide. Females made greater use of medical services than males in both age groups. Suicide prevention strategies should increase the emphasis in training non-psychiatric medical practitioners to identify and treat young persons at suicide risk.

  9. Age at Immigration and Substance Use and Problems Among Males and Females at the U.S.-Mexico Border.

    Although substance use and problems among Mexican Americans are associated with both immigration to the United States and living at the U.S.-Mexico border, little is known about relationships between age at immigration and substance use by gender within the border context. The purpose of this study was to analyze the association of age at immigration with heavy alcohol use, alcohol use disorders (AUD), and drug use among Mexicans Americans living both on and off the U.S.-Mexico border. Household surveys were conducted, using area probability sampling of 2,336 Mexican Americans (1,185 female), ages 18-65, living at the Texas-Mexico border in the metropolitan areas of Laredo and McAllen/Brownsville, and in the nonborder location of San Antonio. Females immigrating before age 12 were less likely to report heavy alcohol use (odds ratio [OR] = 0.309), and those immigrating before age 21 were less likely to report any drug use during the last year compared with their U.S.-born counterparts (OR = 0.473; OR = 0.386, respectively). Males immigrating after age 20 were less likely to report heavy alcohol use (OR = 0.478), and those immigrating between ages 12 and 20 were less likely to report AUD (OR = 0.479) and drug use (OR = 0.255) compared with their U.S.-born counterparts. Early age at immigration (before age 12) was significantly associated with drug use for males living on the border compared with those living off the border. Findings suggest that among females, immigrating before age 12 (vs. being born in the United States) is protective against heavy alcohol and drug use, but among males, immigrating before age 12 results in similarly heavy patterns of use as their U.S.-born counterparts, partially supporting previous findings that early immigration is particularly risky in relation to substance use and AUD.

    2018-01-01

    Full Text Available The harmful effects of objectification and self-objectification have been widely investigated, but few studies have examined factors that may predict self-objectification. This research intends to assess the protective versus risk role of sociodemographic and physical characteristics (age, BMI, psychosocial variables (self-esteem; self-oriented perfectionism and socially prescribed perfectionism, and social factors (influence of family and friends; internalization of media standards on self-objectification in men and women. The selfobjectification was assessed with two subscales of the Objectified Body Consciousness Scale: Body Shame and Body Surveillance. Participants were 812 Italian adults of different age cohorts (age range 21–60 years; 50.7% females recruited via a quota sampling method. Two regression models separately for males and females were performed. Results showed that mass media influence was the strongest predictor for body surveillance and body shame in both men and women, whereas gender-related patterns emerged for physical, psychological, and relational variables with age as moderator.

  12. An investigation into the relationship between pre-competition mood states, age, gender and a national ranking in artistic gymnastics.

    2016-06-01

    This study investigated the relationship between pre-competition mood state factors in gymnastics by gender, age and a national ranking. Participant-gymnasts (total n=116, male n=49, female n=67) completed a Brunel Mood Scale (BRUMS) one day prior to their main competition of the year. Information was also gathered from gymnasts of gender, age and a national ranking. Consistent with theoretical predictions, results confirmed that a number of pre-competition mood states differed by age with both juniors and seniors having a higher level of anger than children (p<.05 respectively). Also, seniors demonstrated higher tension than children (p<.001). However, only anger showed significant differences by gender with male gymnasts demonstrating higher levels of anger than female gymnasts (p<.05), and with international gymnasts registering higher levels of anger compared with second class gymnasts (p<.05). Authors suggest that future research should investigate relationships between the pre-competition mood in other gymnastics-related disciplines and sports, as well as competitive performances.

    Female-to-male gender-confirmation surgery (GCS) includes removal of breasts and female genitalia and complete genital and urethral reconstruction. With a multidisciplinary approach, these procedures can be performed in one stage, avoiding multistage operations. To present our results of one-stage sex-reassignment surgery in female-to-male transsexuals and to emphasize the advantages of single-stage over multistage surgery. During a period of 9 years (2007-2016), 473 patients (mean age = 31.5 years) underwent metoidioplasty. Of these, 137 (29%) underwent simultaneous hysterectomy, and 79 (16.7%) underwent one-stage GCS consisting of chest masculinization, total transvaginal hysterectomy with bilateral adnexectomy, vaginectomy, metoidioplasty, urethral lengthening, scrotoplasty, and implantation of bilateral testicular prostheses. All surgeries were performed simultaneously by teams of experienced gynecologic and gender surgeons. Primary outcome measurements were surgical time, length of hospital stay, and complication and reoperation rates compared with other published data and in relation to the number of stages needed to complete GCS. Mean follow-up was 44 months (range = 10-92). Mean surgery time was 270 minutes (range = 215-325). Postoperative hospital stay was 3 to 6 days (mean = 4). Complications occurred in 20 patients (25.3%). Six patients (7.6%) had complications related to mastectomy, and one patient underwent revision surgery because of a breast hematoma. Two patients underwent conversion of transvaginal hysterectomy to an abdominal approach, and subcutaneous perineal cyst, as a consequence of colpocleisis, occurred in nine patients. There were eight complications (10%) from urethroplasty, including four fistulas, three strictures, and one diverticulum. Testicular implant rejection occurred in two patients and testicular implant displacement occurred in one patient. Female-to-male transsexuals can undergo complete GCS, including mastectomy

    Cytogenetic indicators are widely used in radiobiology to evaluate effects of ionizing radiation since dicentric chromosomes (Dic) are almost exclusively induced by ionizing radiation, and spontaneous frequency of Dic is very low in the healthy general population (about one Dic per 1000 cells). A particular interest of biodosimetry has been not only to obtain absorbed dose estimates using adequate calibration curves, under the assumption that all individuals respond equally to radiation-induced chromosome aberrations, but also to find a way to demonstrate inter-individual radiosensitivity and a possible correlation with age and gender. Thus, the objective of this preliminary work was the evaluation of the influence of age and gender on the outcome of cytogenetic biomarkers after γ-irradiation. Samples of peripheral blood lymphocytes from six healthy, non-smoker, donors from both genders (three men and three women), in the range of 20 to 49 years, were irradiated with doses from 0 Gy to 3 Gy air kerma, using a 60 Co gamma rays source with a dose rate from 170-180 mGy/min. A clear dose-dependent increase in terms of aberrant cells excluding gaps (ACEG) and Dic was observed for all donors. Our preliminary results suggest, in the higher dose level evaluated (3 Gy), a larger intervariability among individuals for Dic, with females apparently more sensitive than males (P<0.05). Considering the different age groups, male donors showed a decrease, with age, for Dic and ACEG at the higher dose and also, for the background level, in case of ACEG. Future work will consider the study of more individuals, from both genders and different ages, in order to verify if this tendency persists and to enable the implementation of a dose-response calibration curve at Instituto Tecnologico e Nuclear for the Portuguese population, to quantify the biological dose in case of a radiological accident or emergency.

  16. What is a typical rape? Effects of victim and participant gender in female and male rape perception

    Anderson, Irina

    2007-01-01

    The study had three research aims: (1) to examine the current perception of female rape. Given recent changes in public awareness of female rape, it was predicted that respondents would conceptualise a typical female rape as an acquaintance rape rather than as the stranger rape stereotype; (2) to examine whether these perceptions differ according to respondents’ gender; (3) to examine the ‘cultural lag’ theory of male rape where it was hypothesised that if the public perception of male rape l...

    Full Text Available Objective. To study the etiological structure of urinary tract infections, dynamics, gender and age dependence in the child population of Chernivtsi region. Patients and methods. During 2009–2013 2432 urine samples of the children treated in health care centers of Chernivtss region were investigated by bacteriological method with purpose of verification of the diagnosis urinary tract infections. Six hundred and fifty five strains of bacteria and fungi were isolated as etiological agents. Results. The patient’s gender was found to correlate with etiological structure of the urinary tract infections and the content of the residential urine microflora. The main etiological role of the Enterobacteriaceae family in general was demonstrated. As a causative agent of the urinary tract infection E.coli has been isolated more frequently in the urine samples of female patients (р < 0.05. In contrary, Proteus spp. has been isolated in male patients (р < 0.01. As a part of the urine resident microflora E.coli strains were more frequently isolated in the female urine samples (р < 0.05. Conclusion. The research will allow to hold the correct and reasoned medical and rehabilitation events on all stages of rendering of specialized medical care for children and to develop the programs directed on the improvement of indicators of health and prevention of disability in children.

  18. Fertility Decline, Gender Composition of Families, and Expectations of Old Age Support.

    Allendorf, Keera

    2015-08-01

    Recent fertility declines in non-Western countries may have the potential to transform gender systems. One pathway for such transformations is the creation of substantial proportions of families with children of only one gender. Such families, particularly those with only daughters, may facilitate greater symmetry between sons and daughters. This article explores whether such shifts may influence gendered expectations of old age support. In keeping with patriarchal family systems, old age support is customarily provided by sons, but not daughters, in India. Using data from the 2005 Indian Human Development Survey, I find that women with sons overwhelmingly expect old age support from a son. By contrast, women with only daughters largely expect support from a daughter or a source besides a child. These findings suggest that fertility decline may place demographic pressure on gendered patterns of old age support and the gender system more broadly.

    Male sexual desire typically declines with ageing. However, our understanding of the neurobiological basis for this phenomenon is limited by our knowledge of the brain circuitry and neuronal pathways controlling male sexual desire. A number of studies across species suggest that dopamine (DA) affects sexual desire. Here we use genetic tools and behavioural assays to identify a novel subset of DA neurons that regulate age-associated male courtship activity in Drosophila. We find that increasing DA levels in a subset of cells in the PPL2ab neuronal cluster is necessary and sufficient for increased sustained courtship in both young and aged male flies. Our results indicate that preventing the age-related decline in DA levels in PPL2ab neurons alleviates diminished courtship behaviours in male Drosophila. These results may provide the foundation for deciphering the circuitry involved in sexual motivation in the male Drosophila brain.

  20. How gender, age, and geography influence the utilization of radiation therapy in the management of malignant melanoma

    French, John; McGahan, Colleen; Duncan, Graeme; Lengoc, Sonca; Soo, Jenny; Cannon, Jerry

    2006-01-01

    Purpose: Comparing radiation therapy utilization rates (RTUR) to those predicted by best evidence is a useful measure of the equity and accessibility of service delivery. In this study the RTUR for melanoma was established for British Columbia, Canada, and compared with the rate suggested by the evidence. Demographic variables, specifically age, gender, and geography that influenced the RTUR were examined with a view to identifying methods of improving underutilization. Methods and Materials: The RTUR in the management of malignant melanoma was taken from British Columbia Cancer registry data for 1986 to 1998. Variations in utilization based on age, gender, health authority, stage of disease, and referral patterns were analyzed. Results: An RTUR of 11% was identified. This was consistent over time. Referral rates decreased between 1986 and 1998. RT is used mostly for later stage disease. Males were more likely to receive RT than females, related to later stage of disease in men. Referral rates decreased, but RTUR for referred cases increased, in health authorities that did not have a cancer center. Conclusions: Use of RT is influenced by age and by stage of disease. Overall RTUR in British Columbia is lower than suggested by best evidence. Referral patterns are influenced by geography. RTUR was higher in males, consistent with a different pattern of disease in males compared with females

  2. Gender and age effects in structural brain asymmetry as measured by MRI texture analysis.

    Kovalev, Vassili A; Kruggel, Frithjof; von Cramon, D Yves

    2003-07-01

    Effects of gender and age on structural brain asymmetry were studied by 3D texture analysis in 380 adults. Asymmetry is detected by comparing the complex 3D gray-scale image patterns in the left and right cerebral hemispheres as revealed by anatomical T1-weighted MRI datasets. The Talairach and Tournoux parcellation system was applied to study the asymmetry on five levels: the whole cerebrum, nine coronal sections, 12 axial sections, boxes resulting from both coronal and axial subdivisions, and by a sliding spherical window of 9 mm diameter. The analysis revealed that the brain asymmetry increases in the anterior-posterior direction starting from the central region onward. Male brains were found to be more asymmetric than female. This gender-related effect is noticeable in all brain areas but is most significant in the superior temporal gyrus, Heschl's gyrus, the adjacent white matter regions in the temporal stem and the knee of the optic radiation, the thalamus, and the posterior cingulate. The brain asymmetry increases significantly with age in the inferior frontal gyrus, anterior insula, anterior cingulate, parahippocampal gyrus, retrosplenial cortex, coronal radiata, and knee region of the internal capsule. Asymmetry decreases with age in the optic radiation, precentral gyrus, and angular gyrus. The texture-based method reported here is based on extended multisort cooccurrence matrices that employ intensity, gradient, and anisotropy features in a uniform way. It is sensitive, simple to reproduce, robust, and unbiased in the sense that segmentation of brain compartments and spatial transformations are not necessary. Thus, it should be considered as another tool for digital morphometry in neuroscience.

    Full Text Available Introduction: Intima-media thickness (IMT measurement of the common carotid artery (CCA is considered as useful indicator of carotid atherosclerosis. Early detection of atherosclerosis and its associated risk factors is important to prevent stroke and heart diseases. The aim of the present study was to investigate which risk factors are better determinants of subclinical atherosclerosis, measured by common carotidartery intima media thickness (CCA-IMT.Methods: A total of 74 subjects were randomly selected in this cross – sectional study. Information on the patient’s medical history and laboratory fi ndings were obtained from their clinical records. Risk factors relevant to this study were age, gender, cigarette smoking status, diabetes, hypertension and dyslipidemia. Ultrasound scanning of carotid arteries was performed with a 7,5 MHz linear array transducer (GE Voluson730 pro. The highest value of six common carotid artery measurements was taken as the fi nal IMT. Increased CCA-IMT was defi ned when it was > 1 mm.Results: Our data demonstrated higher CCA-IMT values in male patients compared with female patients. Increased CCA-IMT was the most closely related to age (P<0.001, followed by systolic blood pressure (P=0.001, diastolic blood pressure (P=0.003 and glucose blood level (P=0.048.Conclusion: Age, gender and hypertension are the most important risk factors in development of carotid atherosclerosis. Early detection of atherosclerosis among high-risk populations is important in order to prevent stroke and heart diseases, which are leading causes of death worldwide.

  4. Same-level fall injuries in US workplaces by age group, gender, and industry.

    Scott, Kenneth A; Fisher, Gwenith G; Barón, Anna E; Tompa, Emile; Stallones, Lorann; DiGuiseppi, Carolyn

    2018-02-01

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

  5. "It's your badge of inclusion": the Red Hat Society as a gendered subculture of aging.

    Barrett, Anne E; Pai, Manacy; Redmond, Rebecca

    2012-12-01

    Although studies document the health-enhancing effects of social engagement, they reveal little about the underlying mechanisms operating within specific organizational contexts. Limited attention is given to the role of inequality--particularly age and gender--in shaping either the organizations to which we belong or their consequences for our well-being. We address this issue by examining the Red Hat Society, a social organization for middle-aged and older women. Interviews with members (n=52) illustrate how age and gender inequality interact to shape the organization, which can be viewed as a gendered subculture of aging. Drawing on this framework, we discuss four processes through which participation generates benefits for older women involved in age- and gender-segregated organizations: enhancing social networks, countering invisibility, creating positive frames for aging experiences, and promoting youthful identities.

    No surgical technique is reported to be the best option for gender-affirmation surgery (GAS) of the genitalia in transmen. Although patients' preferences are central when choosing a surgical technique, no studies have evaluated this factor. To investigate transmen's priorities and preferences regarding GAS of the genitalia. From November 2015 to March 2016, 54 transmen with the diagnosis of gender dysphoria who were referred to Sahlgrenska University Hospital for discussion of therapeutic steps (surgery and hormonal treatments) were asked to complete a questionnaire on different attributes achievable with GAS, such as sexual and urinary function and appearance. Forty-seven patients (87%) completed the questionnaire. Age ranged from 18 to 52 years (mean = 26 years, SD = 7.4 years). At the time of interview, no patient had undergone GAS of the genitalia. Answers to completed questionnaires. Seventy-six percent of patients identified themselves as male, and 24% wrote other terms such as "mostly male," "inter-gender" and "non-binary." Gender identity had a significant impact on patients' preferences for two questions: the importance of vaginal removal and the importance of having a penis that would be passable in places such as male dressing rooms. These items were more important to patients identifying themselves as male. The most important attributes requested were preserved orgasm ability and tactile sensation. The least important attribute was removal of the vagina, followed by having a penis of human material, minimal scarring, and size. The ability to urinate while standing was considered a high priority by some and a low priority by others. All answers ranged from "unimportant" to "imperative." This series of patients demonstrates a considerable heterogeneity among transmen in their gender identity and preferences regarding GAS of the genitalia, which supports the need for several techniques. Patients must be accurately informed on the different techniques and

    This study hypothesized that gender-role nonconformity is associated with suicidality, and bullying mediates this relationship. Gay males retrospectively answered questions pertaining to elementary, middle, and high school. Support for the hypotheses was found. Results can help screen gay youth for suicidality and support the need for policies prohibiting harassment based on sexual orientation.

  9. Gender orientation and alcohol-related weight control behavior among male and female college students.

    Peralta, Robert L; Barr, Peter B

    2017-01-01

    We examine weight control behavior used to (a) compensate for caloric content of heavy alcohol use; and (b) enhance the psychoactive effects of alcohol among college students. We evaluate the role of gender orientation and sex. Participants completed an online survey (N = 651; 59.9% women; 40.1% men). Weight control behavior was assessed via the Compensatory-Eating-and-Behaviors-in Response-to-Alcohol-Consumption-Scale. Control variables included sex, race/ethnicity, age, and depressive symptoms. Gender orientation was measured by the Bem Sex Role Inventory. The prevalence and probability of alcohol-related weight control behavior using ordinal logistic regression are reported. Men and women do not significantly differ in compensatory-weight-control-behavior. However, regression models suggest that recent binge drinking, other substance use, and masculine orientation are positively associated with alcohol-related weight control behavior. Sex was not a robust predictor of weight control behavior. Masculine orientation should be considered a possible risk factor for these behaviors and considered when designing prevention and intervention strategies.

  10. Contribution of Gender, Marital Status, and Age to English Language Teachers’ Burnout

    2014-12-01

    Full Text Available Teaching is a stressful job and can lead to teachers’ burnout. Teachers feel burned out when they experience high levels of emotional exhaustion and depersonalization but low levels of personal accomplishment (Maslach, 1999. A wealth of research is available on this subject but the findings are inconsistent. The present study surveyed the level of burnout among a randomly selected group of English language teachers (n = 315 in Malaysia. It also investigated whether these teachers’ gender, age and marital status could significantly contribute to their burnout levels. Maslach’s Burnout Inventory (Maslach & Jackson, 1986 was used to collect the data. According to the results, the teachers suffered from significantly high levels of burnout in reference to their PA scores. In comparison with the male teachers, female teachers reported significantly higher levels of burnout considering their emotional exhaustion (p = .008, depersonalization (p = .002 and personal accomplishment (p = .000. Additionally, older teachers (aged ≤ 40 were significantly more burned out than their younger colleagues (aged ≥ 30, regarding their depersonalization (p = .001 and personal achievement (p = .000 mean scores. Finally, married teachers indicated significantly higher levels of burnout compared with those who were not married. The study is expected to have useful implications for teachers, administrators, and researchers.

  11. Boys Are Victims, Too: The Influence of Perpetrators' Age and Gender in Sexual Coercion Against Boys.

    Miller, Jacqueline A; Smith, Edward A; Caldwell, Linda L; Mathews, Catherine; Wegner, Lisa

    2018-06-01

    Sexual coercion among adolescent boys in South Africa is an underresearched topic despite the frequency of such events. Although quantitative research has illuminated the prevalence of sexual coercion toward boys, it has provided little understanding of the context of sexual coercion for adolescent boys. Given the often severe consequences of sexual coercion, it is important to further understand these experiences to inform prevention efforts. The current study aims to provide a more nuanced understanding of the context of sexual coercion. Data come from the baseline assessment for a translational research evaluation of a school-based intervention. The current study focuses on a subset of early and middle adolescent boys who reported experiencing sexual coercion ( n = 223). Analyses examine boys' reports of their perpetrators' characteristics and details about the sexual coercion encounter. Logistic regression is used to examine how coercion tactics used by the perpetrator differs depending on the perpetrator's age and gender. Eighth-grade boys were most likely to report that their perpetrator was a similar-aged female and that perpetrator's age played a particularly important role in what tactics were used. Adult perpetrators were more likely to use physical force, threaten them, harass them electronically, and drink or use drugs at the time. Results provide important insight into boys' experiences of sexual coercion that have implications for both future research and intervention efforts. Although much research is needed on the topic, intervention programs should recognize that both male and female adolescents can be victim and perpetrator.

    Andersen, Steffen; Ertac, Seda; Gneezy, Uri

    Economists and other social scientists typically rely on gender differences in the family-career balance, discrimination, and ability to explain gender gaps in wages and in the prospect for advancement. A new explanation that has recently surfaced in the economics literature is that men are more...... competitively inclined than women, and having a successful career requires competitiveness. A natural question revolves around the underlying determinants of these documented competitive differences: are women simply born less competitive, or do they become so through the process of socialization?

  13. Apparent diffusion coefficient measurements of bilateral kidneys at 3 T MRI: Effects of age, gender, and laterality in healthy adults

    Suo, S.-T.; Cao, M.-Q.; Ding, Y.-Z.; Yao, Q.-Y.; Wu, G.-Y.; Xu, J.-R.

    2014-01-01

    Aim: To investigate the effects of age and gender on apparent diffusion coefficient (ADC) measurements of bilateral kidneys at 3 T MRI, and compare the ADC values of left and right kidneys. Materials and methods: In all, 137 healthy participants (mean age 42.8 ± 14.7 years; age range 16–75 years) comprising 68 male and 69 female participants were enrolled. Three Tesla echo-planar diffusion-weighted imaging (DWI) of bilateral kidneys was performed and ADC values were measured in the cortex, medulla, and whole parenchyma. Pearson correlation analysis and linear regression were performed to determine the associations between the ADC values in each region and age. Effects of age and gender on ADC values were analysed using two-factor analysis of variance (ANOVA). The paired-samples t-test was established to compare the ADC values between left and right kidneys. Results: ADC values were significantly higher in the young group (≤50 years) than in the old group (>50 years), and correlated inversely with the age in all regions. Male participants had higher ADC values than female participants in all regions except left medulla. Two-factor ANOVA of age × gender showed no significant interactions between the variables age and gender were found. No significant differences in ADC values between left and right kidneys were observed. Conclusion: Renal ADC values are age- and gender-dependent, and show no significant difference between left and right kidneys. Age- and gender-related effects should be taken into consideration in future renal DWI studies when using normal ADC values from health controls. - Highlights: • Renal apparent diffusion coefficient (ADC) values decrease with ageing. • Men tend to have higher renal ADC values than women. • Bilateral kidneys seem to have no significantly different ADC values

  16. Relation of cigarette smoking in males of different ages to sex hormone binding globulin and testosterone

    El-Nabarawy, F.S.

    2002-01-01

    The relationship of cigarette smoking, age, total testosterone free testosterone and sex hormone binding globulin (SHBG) were examined by solid phase radioimmunoassay in 90 randomly chosen healthy males of different ages. The serum levels of these hormones were investigated for smokers compared with non-smokers, of the same ages in 3 groups (adolescent males, middle aged males, and old aged males). Results indicated that cigarette smokers showed increased serum levels of testosterone (60.0% higher, P> 0.05), free testosterone (51.0 higher, P > 0.005) in young adolescent males group, testosterone (27.8% higher, P > 0.001), free testosterone (21.3% higher, P > 0.001) in middle aged males group, and testosterone (21.0% higher, P > 0.001), free testosterone (16.8% higher, P > 0.4) in old ages males group. SHBG was calculated as a mean of free and total testosterone in each group. smokers showed higher mean values of SHBG than non-smokers. Age was positively associated with serum SHBG, it was found that SHBG increased by 17.2% from the youngest (> 18 years) to the oldest age (> 65 years)

    2013-01-01

    The purpose of this study was to assess middle-aged Japanese workers for possible gender differences in the risk factors associated with depressive symptoms and suicidal ideation. 5,878 workers (40-60 yr of age) (3,631 males and 2,247 females) were recruited from randomly selected companies in northern Japan. Demographic and lifestyle factors, suicidal ideation rate, and the data for the Brief Job Stress Questionnaire (BJSQ) and the Center for Epidemiologic Studies for Depression scale (CES-D) were obtained from the self-report questionnaires. After adjusting for possible confounding variables, marital status, absent of stress reduction technique and low job compatibility were significant independent risk factors for suicidal ideation among males. In females, marital status, feeling of insufficient sleep and absence of stress reduction techniques were significant independent risk factors after adjusting for all variables. Under the same adjustments, temporary employment also showed a protective effect against female suicidal ideation. In conclusion, our results suggest that factors related to suicidal ideation differed by gender. Different approaches for each gender might be useful in the development of suicide prevention programs. However, interpretation of work-related effects, such as temporary employment, interpersonal conflict and transportation industry, was hampered by lack of data concerning personal income, working hours and organizational commitment. Additional studies are needed to examine the longitudinal relationships between the risk factors associated with suicidal ideation and depressive symptoms.

  18. Is gender a factor in perceived prison officer competence? Male prisoners' perceptions in an English dispersal prison.

    Boyd, Elizabeth; Grant, Tim

    2005-01-01

    The introduction of women officers into HM Prison Service raised questions regarding women's ability to perform what had traditionally been a male role. Existing research is inconclusive as to whether female prison officers are as competent as male prison officers, and whether there are gender differences in job performance. This study examined prisoners' perceptions of male and female prison officers' performance. The hypotheses were that overall competence and professionalism ratings would not differ for men and women officers, but that there would be differences in how men and women were perceived to perform their roles. Women were expected to be rated as more communicative, more empathic and less disciplining. The Prison Officer Competency Rating Scale (PORS) was designed for this study. Ratings on the PORS for male and female officers were given by 57 adult male prisoners. There was no significant difference in prisoners' ratings of overall competence of men and women officers. Of the PORS subscales, there were no gender differences in Discipline and Control, Communication or Empathy, but there was a significant difference in Professionalism, where prisoners rated women as more professional. The failure to find any differences between men and women in overall job competence, or on communication, empathy and discipline, as perceived by prisoners, suggests that men and women may be performing their jobs similarly in many respects. Women were rated as more professional, and items contributing to this scale related to respecting privacy and keeping calm in difficult situations, where there may be inherent gender biases.

    The goal of this investigation was to examine gender differences in experiences of sexual harassment during military service and the negative mental health symptoms associated with these experiences. Female (n = 2,319) and male (n = 1,627) former reservists were surveyed about sexual harassment during their military service and current mental health symptoms. As expected, women reported a higher frequency of sexual harassment. Further, women had increased odds of experiencing all subtypes of sexual harassment. Being female conferred the greatest risk for experiencing the most serious forms of harassment. For both men and women, sexual harassment was associated with more negative current mental health. However, at higher levels of harassment, associations with some negative mental health symptoms were stronger for men than women. Although preliminary, the results of this investigation suggest that although women are harassed more frequently than men, clinicians must increase their awareness of the potential for sexual harassment among men in order to provide the best possible care to all victims of harassment.

  20. The contribution of gender-role orientation, work factors and home stressors to psychological well-being and sickness absence in male- and female-dominated occupational groups.

    Evans, Olga; Steptoe, Andrew

    2002-02-01

    The associations of work stress, types of work and gender-role orientation with psychological well-being and sickness absence were investigated in a questionnaire survey of 588 male and female nurses and 387 male and female accountants. We hypothesised that health might be impaired among women working in the male-dominated occupation (accountancy), and men in the female-dominated occupation (nursing), but that effects might be moderated by job strain (perceptions of high demand and low control), work and home hassles, and traditional male (instrumentality) and female (expressivity) psychological characteristics. Responses were analysed from 172 female and 61 male nurses, and from 53 female and 81 male commercial accountants. Female accountants were more likely than other groups to have high anxiety scores on the Hospital Anxiety and Depression Scales, while male nurses had the highest rates of sickness absence. Male nurses and female accountants also reported more work-related hassles than did female nurses and male accountants. Men and women in the same occupation did not differ in job strain or job social support, but nurses reported greater job strain than accountants, due to higher ratings of demands and lower skill utilisation. After adjusting for age, sex, occupation, paid work hours and a measure of social desirability bias, risk of elevated anxiety was independently associated with higher job strain, lower job social support, more work hassles, more domestic responsibility, lower instrumentality and higher expressivity. The association between sex and anxiety was no longer significant after instrumentality had been entered into the regression model. Sickness absence of more than three days over the past 12 months was independently associated with higher job strain, more work hassles, lower instrumentality and higher expressivity. The results suggest that when men and women occupy jobs in which they are in the cultural and numerical minority, there may be

  1. Sex differences in gender characteristics of Australian nurses and male engineers: a comparative cross-sectional survey.

    J Fisher, Murray

    2011-08-01

    There continue to be assumptions within the nursing literature that nursing is synonymous with a feminine sex role identity. A comparative cross-sectional survey consisting of the Bem Sex Role Inventory and the Australian sex role scale was used to determine sex difference in gender characteristics of Australian nurses and with male engineers. A statistically significant difference in femininity was found between all the samples (F((2,908)) = 20.24, p orientation (t = 27.67) and self display (t = 12.42). Whilst differences in expressive characteristics were found between male and female nurses, a similar difference was found between male nurses and male engineers, supporting the notion that male nurses perceive themselves as having feminine characteristics essentially required for nursing.

    Alcohol use disorders (AUD) are 2 times higher among psychiatric patients than in the general population. The under-recognition of this dual diagnosis can entail several negative outcomes. Early assessment with a screening tool like the CAGE questionnaire could be an opportunity to improve patients' prognoses. The objective of this study is to assess AUD risk in an outpatient psychiatric sample with a modified CAGE, considering the influence of age, gender and clinical psychiatric diagnosis. An observational, multicentric, descriptive study was carried out. The 4-item CAGE scale, camouflaged in a healthy lifestyle questionnaire, was implemented, using a cut-off point of one. 559 outpatients were assessed. 54% were female and the average age was 50.07 years. 182 patients presented a CAGE score ≥1 (45.1% of men and 21.9% of women). Gender was the strongest predictor of a positive result in CAGE, as men were 3.03 times more likely to score ≥1 on the CAGE questionnaire (p < .001, 95% CI: 0.22-0.49). Patients with bipolar and personality disorders had the highest rates of CAGE scores ≥1 (45.2 and 44.9%, respectively), with a significant association between diagnosis and a positive score (p = .002). Patients above 60 years were 2.5 times less likely to score ≥1 on the CAGE (p = .017, 95% CI: 0.19-0.85). Specific screening questionnaires, like the CAGE scale, can be an easy and useful tool in the assessment of AUD risk in psychiatric outpatients. Male patients with a bipolar or personality disorder present a higher risk of AUD.

  10. Age- and gender-specific epistasis between ADA and TNF-α influences human life-expectancy.

    Aging is a complex phenotype with multiple determinants but a strong genetic component significantly impacts on survival to extreme ages. The dysregulation of immune responses occurring with increasing age is believed to contribute to human morbidity and mortality. Conversely, some genetic determinants of successful aging might reside in those polymorphisms for the immune system genes regulating immune responses. Here we examined the main effects of single loci and multi-locus interactions to test the hypothesis that the adenosine deaminase (ADA) and tumor necrosis factor alpha (TNF-α) genes may influence human life-expectancy. ADA (22G>A, rs73598374) and TNF-α (-308G>A, rs1800629; -238G>A, rs361525) functional SNPs have been determined for 1071 unrelated healthy individuals from Central Italy (18-106 years old) divided into three gender-specific age classes defined according to demographic information and accounting for the different survivals between sexes: for men (women), the first class consists of individuals88 years old (>91 years old). Single-locus analysis showed that only ADA 22G>A is significantly associated with human life-expectancy in males (comparison 1 (age class 2 vs. age class 1), O.R. 1.943, P=0.036; comparison 2 (age class 3 vs. age class 2), O.R. 0.320, P=0.0056). Age- and gender-specific patterns of epistasis between ADA and TNF-α were found using Generalized Multifactor Dimensionality Reduction (GMDR). In comparison 1, a significant two-loci interaction occurs in females between ADA 22G>A and TNF-α -238G>A (Sign Test P=0.011). In comparison 2, both two-loci and three-loci interaction are significant associated with increased life-expectancy over 88 years in males. In conclusion, we report that a combination of functional SNPs within ADA and TNF-α genes can influence life-expectancy in a gender-specific manner and that males and females follow different pathways to attain longevity.

  11. Effect of age and gender on the surface electromyogram during various levels of isometric contraction.

    Arjunan, Sridhar; Kumar, Dinesh; Kalra, Chandan; Burne, John; Bastos, Teodiano

    2011-01-01

    This study reports the effects of age and gender on the surface electromyogram while performing isometric contraction. Experiments were conducted with two age groups--Young (Age: 20-29) and Old (Age: 60-69) where they performed sustained isometric contractions at various force levels (50%, 75%, 100% of maximum voluntary contraction). Traditional features such as root mean square (RMS) and median frequency (MDF) were computed from the recorded sEMG. The result indicates that the MDF of sEMG was not significantly affected by age, but was impacted by gender in both age groups. Also there was a significant change in the RMS of sEMG with age and gender at all levels of contraction. The results also indicate a large inter-subject variation. This study will provide an understanding of the underlying physiological effects of muscle contraction and muscle fatigue in different cohorts.

    = 0.478). The study material was large enough to detect differences between birthweights as a whole, but a larger study group would confirm these new findings. To avoid selection bias, the next possible control candidate, fulfilling the selection criteria, was included for matching cases and controls. We have matched the cases and controls by gender and gestational week at birth, with an aim to reduce their impact as confounding factors. Our findings of a similar weight at birth of newborns after frozen-thawed blastocysts and frozen-thawed cleavage stage embryos, when matching for age and duration of pregnancy, are novel. The gender of the newborn has an impact on the birthweight, and the extended embryo culture increases the weight difference between the genders, which is a new finding as well.

    Full Text Available Abstract Background Knowledge about age-specific normal values for left ventricular mass (LVM, end-diastolic volume (EDV, end-systolic volume (ESV, stroke volume (SV and ejection fraction (EF by cardiac magnetic resonance imaging (CMR is of importance to differentiate between health and disease and to assess the severity of disease. The aims of the study were to determine age and gender specific normal reference values and to explore the normal physiological variation of these parameters from adolescence to late adulthood, in a cross sectional study. Methods Gradient echo CMR was performed at 1.5 T in 96 healthy volunteers (11–81 years, 50 male. Gender-specific analysis of parameters was undertaken in both absolute values and adjusted for body surface area (BSA. Results Age and gender specific normal ranges for LV volumes, mass and function are presented from the second through the eighth decade of life. LVM, ESV and EDV rose during adolescence and declined in adulthood. SV and EF decreased with age. Compared to adult females, adult males had higher BSA-adjusted values of EDV (p = 0.006 and ESV (p Conclusion LV volumes, mass and function vary over a broad age range in healthy individuals. LV volumes and mass both rise in adolescence and decline with age. EF showed a rapid decline in adolescence compared to changes throughout adulthood. These findings demonstrate the need for age and gender specific normal ranges for clinical use.

  17. Conception, pregnancy, and birth experiences of male and gender variant gestational parents: it's how we could have a family.

    2015-01-01

    Like members of any other population, transgender and gender variant people--individuals whose gender identity varies from the traditional norm or from the sex they were assigned at birth--often seek parenthood. Little is known about the decision making and experiences of these individuals, including male-identified and gender-variant natal females who wish to achieve parenthood by carrying a pregnancy. This pilot qualitative study used grounded theory methodology to explore the conception, pregnancy, and birth experiences of this population of parents. A grounded theory methodology was used to guide data collection and analysis. Eight male-identified or gender-variant gestational parents participated in the study. Data collection included individual 60-minute to 90-minute interviews conducted by recorded online video calls, as well as a self-administered online demographic survey. Data were collected from September 2011 through May 2012. Data saturation was achieved at 6 interviews, after which 2 more interviews were conducted. The interviews were transcribed verbatim, and a constant comparative method was used to analyze the interview transcripts. Loneliness was the overarching theme that permeated participants' experiences, social interactions, and emotional responses during every stage of achieving biologic parenthood. Within this context of loneliness, participants described complex internal and external processes of navigating identity. Navigating identity encapsulated 2 subthemes: undergoing internal struggles and engaging with the external world. The preconception period was identified as participants' time of greatest distress and least involvement with health care. The findings of this study suggest that culturally-sensitive preconception counseling could be beneficial for transgender and gender-variant individuals. The grounded theory produced by this pilot investigation also provides insights that will be useful to health care providers and others

    Full Text Available Objective:The aim of this study was to define the distribution of the incidence and location of Helicobacter pylori in terms of the age and gender in the gastritis patients undergone endoscopy. Methods:Endoscopy and pathology reports of 1,405 patients who undergone biopsy of upper gastrointestinal system endoscopy were retrospectively examined. The frequency and location of Helicobacter pylori infection were evaluated according to the locations, gender and age groups. Based on the Sydney classification, the patients were scored as none (-, low (+, medium (++ and high (+++. Results: A total of 1405 patients (58.6% females, 41.4% males who had both antrum and corpus biopsies were included. Mean age was 48.58±16.96 (15-94 years. The Helicobacter pylori positivity was significantly higher in males than in the female patients (p=0.012. Helicobacter pylori positivity both in corpus and antrum was 1,101 (78.4%, Helicobacter pylori was negative in 304 (21.6% patients. Although, females had higher positivity rate, no significant difference was found between the age and gender groups. In 1,064 patients (75.7% Helicobacter pylori was positive while it was found as negative in 341 (24.3% biopsies taken from the antrum. While in 572 (40.7% of the biopsy outcomes taken from the corpus Helicobacter pylori was found as positive, it was found as negative in 833 (59.3%. No statistically significant differences were found between the age groups in terms of the positivity of Helicobacter pylori both in antrum and in corpus. Conclusion: In our study, the frequency of the Helicobacter pylori positivity was 78.4%. This can be accepted as a serious public health problem in terms of the associated diseases.

  19. Haploinsufficiency in the PPARα and LDL receptor genes leads to gender- and age-specific obesity and hyperinsulinemia

    When preparing peroxisome proliferator-activated receptor (PPAR)α:low-density lipoprotein receptor (LDLR) (-/-) double knockout mice, we unexpectedly found a unique gender- and age-specific obesity in the F1 generation, PPARα (+/-):LDLR (+/-), even in mice fed standard chow. Body weights of the male heterozygous mice increased up to about 60 g at 75 weeks of age, then decreased by about 30 g at 100 weeks of age. More than 95% of the heterozygous mice between 35- and 75-week-olds were overweight. Of interest, the obese heterozygous mice also exhibited hyperinsulinemia correlating with moderate insulin resistance. Hepatic gene expression of LDLR was lower than expected in the heterozygous mice, particularly at 50 and 75 weeks of age. In contrast, the hepatic expression of PPARα was higher than expected in obese heterozygous mice, but decreased in non-obese older heterozygous mice. Modulated expression of these genes may be partially associated with the onset of the hyperinsulinemia

  11. Age group classification and gender detection based on forced expiratory spirometry.

    Cosgun, Sema; Ozbek, I Yucel

    2015-08-01

    This paper investigates the utility of forced expiratory spirometry (FES) test with efficient machine learning algorithms for the purpose of gender detection and age group classification. The proposed method has three main stages: feature extraction, training of the models and detection. In the first stage, some features are extracted from volume-time curve and expiratory flow-volume loop obtained from FES test. In the second stage, the probabilistic models for each gender and age group are constructed by training Gaussian mixture models (GMMs) and Support vector machine (SVM) algorithm. In the final stage, the gender (or age group) of test subject is estimated by using the trained GMM (or SVM) model. Experiments have been evaluated on a large database from 4571 subjects. The experimental results show that average correct classification rate performance of both GMM and SVM methods based on the FES test is more than 99.3 % and 96.8 % for gender and age group classification, respectively.

  3. Morphology and ornamentation in male frigatebirds: variation with age-class and mating status

    Madsen, Vinni; Dabelsteen, Torben; Osorio, Daniel

    2007-01-01

    of white in the plumage identifies three age classes of nonjuvenile male. Here we investigate how morphological and secondary sexual traits correlate with age class and mating status. Even though several age class-related differences in morphology and visual appearance can be identified, the only features...... with age class, reflecting an increase in gular pouch size. This implies that females prefer older or possibly more experienced or viable males. Drumming cadence speed and stability might reflect male stamina. Apart from the acoustic differences with mating status, there is a nonsignificant tendency...... for back-feather iridescence to be of shorter reflectance wavelength spectra in mated than in unmated males, which, when combined with acoustic variables, improves prediction of age class and mating status....

  4. Differential item functioning of pathological gambling criteria: an examination of gender, race/ethnicity, and age.

    Sacco, Paul; Torres, Luis R; Cunningham-Williams, Renee M; Woods, Carol; Unick, G Jay

    2011-06-01

    This study tested for the presence of differential item functioning (DIF) in DSM-IV Pathological Gambling Disorder (PGD) criteria based on gender, race/ethnicity and age. Using a nationally representative sample of adults from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), indicating current gambling (n = 10,899), Multiple Indicator-Multiple Cause (MIMIC) models tested for DIF, controlling for income, education, and marital status. Compared to the reference groups (i.e., Male, Caucasian, and ages 25-59 years), women (OR = 0.62; P gambling to escape (Criterion 5) (OR = 2.22; P < .001) but young adults (OR = 0.62; P < .05) were less likely to endorse it. African Americans (OR = 2.50; P < .001) and Hispanics were more likely to endorse trying to cut back (Criterion 3) (OR = 2.01; P < .01). African Americans were more likely to endorse the suffering losses (OR = 2.27; P < .01) criterion. Young adults were more likely to endorse chasing losses (Criterion 9) (OR = 1.81; P < .01) while older adults were less likely to endorse this criterion (OR = 0.76; P < .05). Further research is needed to identify factors contributing to DIF, address criteria level bias, and examine differential test functioning.

  6. Highly sensitive C-reactive protein and male gender are independently related to the severity of coronary disease in patients with metabolic syndrome and an acute coronary event

    C.M.C. Monteiro

    2010-03-01

    Full Text Available Patients with metabolic syndrome are at high-risk for development of atherosclerosis and cardiovascular events. The objective of this study was to examine the major determinants of coronary disease severity, including those coronary risk factors associated with metabolic syndrome, during the early period after an acute coronary episode. We tested the hypothesis that inflammatory markers, especially highly sensitive C-reactive protein (hsCRP, are related to coronary atherosclerosis, in addition to traditional coronary risk factors. Subjects of both genders aged 30 to 75 years (N = 116 were prospectively included if they had suffered a recent acute coronary syndrome (acute myocardial infarction or unstable angina pectoris requiring hospitalization and if they had metabolic syndrome diagnosed according to the National Cholesterol Education Program/Adult Treatment Panel III. Patients were submitted to a coronary angiography and the burden of atherosclerosis was estimated by the Gensini score. The severity of coronary disease was correlated (Spearman’s or Pearson’s coefficient with gender (r = 0.291, P = 0.008, age (r = 0.218, P = 0.048, hsCRP (r = 0.256, P = 0.020, ApoB/ApoA ratio (r = 0.233, P = 0.041, and carotid intima-media thickness (r = 0.236, P = 0.041. After multiple linear regression, only male gender (P = 0.046 and hsCRP (P = 0.012 remained independently associated with the Gensini score. In this high-risk population, male gender and high levels of hsCRP, two variables that can be easily obtained, were associated with more extensive coronary disease, identifying patients with the highest potential of developing new coronary events.

  8. Age and Gender Differences in Relationships Among Emotion Regulation, Mood, and Mental Health

    Kouhei Masumoto PhD

    2016-03-01

    Full Text Available Objective: We investigated the effects of age on mood and mental health-mediated emotion regulation, such as cognitive reappraisal and expressive suppression, and examined whether these relationships differ according to gender. Method: We recruited 936 Japanese participants. They comprised six age groups ranging from 20 to 70 years old, with 156 participants in each age group and equal numbers of men and women. Results: Structural equation model analysis showed that older participants were more likely to use cognitive reappraisal, further enhancing positive mood and reducing negative mood, whereas, age did not affect expressive suppression. Moreover, expressive suppression had a smaller impact on mood than cognitive reappraisal. A multi-group analysis showed significant gender differences. In men, cognitive reappraisal increased with age and influenced mood more positively than in women. Discussion: Our findings indicated gender differences in aging effects on emotion regulation. We discussed about these results from the cognitive process, motivation to emotion regulation, and cultural differences.

To determine if the preferences indicated by copulations appear in other contexts as well as how they interact, we examined how male chimpanzees' grooming patterns varied amongst females. We found...... that males' preferences were based on interactions among females' fertility status, age, and parity. First, grooming increased with increasing female parity. We further found an effect of the estrous cycle on grooming; when females were at the lowest point of their cycle, males preferentially groomed parous...... females at peak reproductive age, but during maximal tumescence, males preferred the oldest multiparous females. Nulliparous females received relatively little grooming regardless of age or fertility. Thus, male chimpanzees apparently chose grooming partners based on both female's experience and fertility...

    Awareness of gender dysphoria (GD) and its treatment is increasing. There is paucity of scientific data from India regarding the therapeutic options being used for alleviating GD, which includes psychotherapy, hormone, and surgical treatments. To study the therapeutic options including psychotherapy, hormone, and surgical treatments used for alleviating GD. This is a retrospective study of treatment preferences and outcome in 18 female-to-male (FTM) transgender subjects who presented to the endocrine clinic. The mean follow-up was 1.6 years and only one subject was lost to follow-up after a single visit. All subjects desiring treatment had regular counseling and medical monitoring. All FTM subjects were cross-dressing. Seventeen (94.4%) FTM subjects were receiving cross-sex hormone therapy, in the form of testosterone only (61.1%) or gonadotropin-releasing hormone (GnRH) agonist in combination with testosterone (11.1%) or medroxyprogesterone acetate (MPA) depot in combination with testosterone (22.2%). FTM subjects preferred testosterone or testosterone plus MPA; very few could afford GnRH therapy. Testosterone esters injection was preferred by most (72.2%) subjects as it was most affordable while 22.2% chose 3 monthly injections of testosterone undecanoate for convenience and better symptomatic improvement, but it was more expensive. None preferred testosterone gels because of cost and availability concerns. About 33.3% of our subjects underwent mastectomy, 38.9% had hysterectomy with bilateral salpingo-oophorectomy, and only one subject underwent phalloplasty. About 16.7% of FTM subjects presented with prior mastectomy depicting a high prevalence of unsupervised or poorly supervised surgeries not following protocol wise approach.

    Gender dysphoria (GD) is an increasingly recognized medical condition in India, and little scientific data on treatment outcomes are available. Our objective is to study the therapeutic options including psychotherapy, hormone, and surgical treatments used for alleviating GD in male-to-female (MTF) transgender subjects in Eastern India. This is a retrospective study of treatment preferences and outcome in 55 MTF transgender subjects who were presented to the endocrine clinic. Descriptive statistical analysis is carried out in the present study, and Microsoft Word and Excel are used to generate graphs and tables. The mean follow-up was 1.9 years and 14 subjects (25.5%) were lost to follow-up after a single or 2-3 contact sessions. Rest 41 subjects (74.5%) desiring treatment had regular counseling and medical monitoring. All 41 subjects were dressing to present herself as female and all of them were receiving cross-sex hormone therapy either estrogen only (68%), or drospirenone in combination with estrogen (12%) or gonadotropin-releasing hormone agonist (GnRH) in combination with estrogens (19.5%). Most of the subjects preferred estrogen therapy as it was most affordable and only a small number of subjects preferred drospirenone or GnRH agonist because of cost and availability. 23.6% subjects underwent esthetic breast augmentation surgery and 25.5% underwent orchiectomy and/or vaginoplasty. Three subjects presented with prior breast augmentation surgery and nine subjects presented with prior orchiectomy without vaginoplasty, depicting a high prevalence of poorly supervised surgeries. Standards of care documents provide clinical guidance for health professionals about the optimal management of transsexual people. The lack of information among health professionals about proper and protocolwise management leads to suboptimal physical, social, and sexual results.

    Reference data files support the evaluation of myocardial perfusion single-photon emission tomography (SPET). The aim of this study was to create a large reference data base for technetium-99m sestamibi SPET, age and gender matched to the general patient population. One hundred and twenty-eight healthy volunteers (76 males and 52 females) with a likelihood of coronary artery disease of less than 5% underwent rest and maximal exercise 99m Tc-sestamibi SPET with a 2-day protocol and 180 elliptical rotation. The normalized activity values of 99m Tc-sestamibi in the inferior wall differed significantly between men and women. Age variations were found for men in the anterior wall. Normalized activity values in all four walls were strikingly similar during rest and stress. Our results suggest that the use of reference files in 99m Tc-sestamibi SPET requires a gender- and, for males, possibly an age-matched reference population. Different reference files at rest and during stress might not be necessary. (orig.). With 3 figs., 3 tabs

  17. Age, sex and (the) race: gender and geriatrics in the ultra-endurance age.

    Whyte, Greg

    2014-01-01

    Ultra-endurance challenges were once the stuff of legend isolated to the daring few who were driven to take on some of the greatest physical endurance challenges on the planet. With a growing fascination for major physical challenges during the nineteenth century, the end of the Victorian era witnessed probably the greatest ultra-endurance race of all time; Scott and Amundsen's ill-fated race to the South Pole. Ultra-endurance races continued through the twentieth century; however, these events were isolated to the elite few. In the twenty-first century, mass participation ultra-endurance races have grown in popularity. Endurance races once believed to be at the limit of human durability, i.e. marathon running, are now viewed as middle-distance races with the accolade of true endurance going to those willing to travel significantly further in a single effort or over multiple days. The recent series of papers in Extreme Physiology & Medicine highlights the burgeoning research data from mass participation ultra-endurance events. In support of a true 'mass participation' ethos Knetchtle et al. reported age-related changes in Triple and Deca Iron-ultra-triathlon with an upper age of 69 years! Unlike their shorter siblings, the ultra-endurance races appear to present larger gender differences in the region of 20% to 30% across distance and modality. It would appear that these gender differences remain for multi-day events including the 'Marathon des Sables'; however, this gap may be narrower in some events, particularly those that require less load bearing (i.e. swimming and cycling), as evidenced from the 'Ultraman Hawaii' and 'Swiss Cycling Marathon', and shorter (a term I used advisedly!) distances including the Ironman Triathlon where differences are similar to those of sprint and endurance distances i.e. c. 10%. The theme running through this series of papers is a continual rise in participation to the point where major events now require selection races to remain

  18. Measurement of empathy among Argentine cardiologists: Psychometrics and differences by age, gender, and subspecialty.

    Borracci, Raúl Alfredo; Doval, Hernán C; Nuñez, Carmen; Samarelli, Marisa; Tamini, Susana; Tanus, Eduardo

    2015-01-01

    Cardiologists are involved in the management of patients with multiple cardiovascular risk factors and chronic heart diseases, so empathy is a necessary feature to deal with them. The aim of the study was to evaluate the validity and reliability of the Spanish version of the Jefferson Scale of Physician Empathy (JSPE) among Argentine cardiologists and to explore the potential differences by age, gender, and subspecialty. Between August and September 2012, we performed a survey in a non-randomized sample of 566 Spanish-speaking cardiologists of Argentina. A Principle Component Analysis (PCA) was used to explore the link between observed variables and latent variables in order to identify the factor structure. The PCA criteria for identifying the factor structure were examined with the Kaiser-Meyer-Olkin (KMO) analysis. The KMO measure of sampling adequacy was 0.86 and Bartlett's test of sphericity was highly significant (p = 0.000), determining the suitability of the data set for factor analysis. The PCA of 20 items yielded a three factor model that accounted for 40.6% of the variance. The JSPE mean rank score for women was 307.9 vs. 275.0 for men (p = 0.017). The comparison of mean rank score according to age (quartiles) showed a significant relation between older age and empathy. No difference was found when the mean rank scores were compared by respondent subspecialty. JSPE provides a valid and reliable scale to measure Argentine cardiologists' attitudes towards empathy. Female cardiologists seem to be more empathic than their male colleagues, and a positive relationship between age and empathy was found.

  19. Study on the relationship between bone metabolism indexes and osteoporosis in aged males

    Luo Nanping; Yang Daoli; Zhao Yutang; Peng Liyi; Liu Guixiang

    2001-01-01

    Objective: To investigate the characteristics and significance of the changes of bone metabolism indexes related to the occurrence of osteoporosis in aged males. Methods: Serum interleukin 1β(IL-1β), insulin-like growth factor II (IGF-II), parathyroid hormone (PTH-M) and 25-OH-D were measured by radio-immunoassay in 58 aged males with osteoporosis and 37 cases with bone mass loss. Bone density was measured in these subjects and all the indexes were compared with those in young and middle-aged and aged healthy controls. Results: IL-1β and PTH-M levels in aged males with osteoporosis or bone mass loss were higher than those in healthy controls (P < 0.01), while IGF-II and 25-OH-D were lower than in normal controls, especially in osteoporosis group (P < 0.01). With the age increasing and the deterioration of the disorder, bone density in the two groups of patients were significantly lower than those in young and middle-aged controls (P < 0.01). Aged males with osteoporosis had a significantly lower bone density than patients with bone mass loss. Conclusion: Cytokines and disturbance of bone metabolism indexes are the main factors that lead to osteoporosis characterized by more bone absorption and less bone formation in aged males

  20. Does Manager Gender Matter? : The Association between Female Manager and Wages of Male and Female Employees

    Hultqvist, Maria

    2015-01-01

    Women in the Swedish labor market have lower wage than men on average. There are multiple reasons for this gender wage differential. Among other things, processes at the organizational level have been stressed. Some researchers argue that the gender of the manager has an effect on wages and that this effect might differ for men and women. Prior studies have analyzed the potential effect of manager gender on wages, but few empirical studies have scrutinized the question. The studies that exist...

  1. Older women and sexuality: Narratives of gender, age, and living environment.

    Jen, Sarah

    2017-01-01

    Little research has explored the intersection of aging and sexuality. This qualitative study is informed by a life course approach and narrative gerontology methods. Semistructured interviews were conducted with 13 women age 55 and older to explore the effects of gender, aging, and living environment on past and current sexual experiences. Subthemes from each major theme are discussed, including: (a) messages about and perceived effects of gender, (b) perceived effects of aging, and (c) perceived effects of living environment. Findings support the use of dynamical systems theory to study women's sexual experiences.

  2. The relevance of age and nutritional status on the mating competitiveness of medfly males (Diptera: Teprhitidae

    Alzira Kelly Passos Roriz

    2013-10-01

    Full Text Available Results of previous investigations trying to ascertain which physiological factors are more important to the mating success of medfly males are controversial. In part, this controversy owes to the fact that each factor was evaluated by an independent study using different experimental designs and populations. In the present study we compare the roles of age and nutritional status (immature and adult phases on the mating competitiveness of Ceratitis capitata (Wiedemann, 1824 males. Three parameters were used to evaluate the male mating success: calling behavior (pheromone emission, lek participation and copulation (ability to be chosen by a female. Females gave preference to the males that were given a high protein diet in the larval phase. By contrast, females did not give preference to males that had been well-nourished in the adult phase only. The other parameters evaluated followed the same pattern: young males and males that had been fed a high protein diet during their immature phase had a greater participation in leks and called more often than older males and males that had been fed a diet poor in protein during their larval phase. Therefore, we conclude that the mating success of C. capitata males is determined both by age and nourishment during the immature stage.

  3. Relationships among age, gender, anthropometric characteristics, and dynamic balance in children 5 to 12 years old.

    Butz, Sarah M; Sweeney, Jane K; Roberts, Pamela L; Rauh, Mitchell J

    2015-01-01

    To examine relationships among age, gender, anthropometrics, and dynamic balance. Height, weight, and arm and foot length were measured in 160 children with typical development aged 5 to 12 years. Dynamic balance was assessed using the Timed Up and Go (TUG) test, Pediatric Reach Test (PRT), and Pediatric Balance Scale (PBS). Moderate to good positive relationships (r = 0.61 and r = 0.56) were found between increasing age and PRT and PBS scores. A fair negative relationship (r = -0.49) was observed between age and TUG test. No significant gender-by-age group difference was observed. Age had the strongest influence on TUG and PBS scores; arm length had the strongest influence on PRT scores. Dynamic balance ability is directly related to chronological age. Age and arm length have the strongest relationships with balance scores. These findings may assist pediatric therapists in selecting dynamic balance tests according to age rather than specific diagnosis.

  4. Gender and age differences in parent-child emotion talk.

    Aznar, Ana; Tenenbaum, Harriet R

    2015-03-01

    This study examined gender differences in emotion word use during mother-child and father-child conversations. Sixty-five Spanish mothers and fathers and their 4- (M = 53.50, SD = 3.54) and 6-year-old (M = 77.07, SD = 3.94) children participated in this study. Emotion talk was examined during a play-related storytelling task and a reminiscence task (conversation about past experiences). Mothers mentioned a higher proportion of emotion words than did fathers. During the play-related storytelling task, mothers of 4-year-old daughters mentioned a higher proportion of emotion words than did mothers of 4-year-old sons, whereas fathers of 4-year-old daughters directed a higher proportion of emotion words than did fathers of 4-year-old sons during the reminiscence task. No gender differences were found with parents of 6-year-old children. During the reminiscence task daughters mentioned more emotion words with their fathers than with their mothers. Finally, mothers' use of emotion talk was related to whether children used emotion talk in both tasks. Fathers' use of emotion talk was only related to children's emotion talk during the reminiscence task. © 2014 The British Psychological Society.

  5. Women and substance abuse: gender, age, and cultural considerations.

    Stevens, Sally J; Andrade, Rosi A C; Ruiz, Bridget S

    2009-01-01

    Historically, data has shown that a smaller percentage of women use alcohol and illicit substances compared to men, and that frequency of use has been lower among women compared to use among men. Although this data on usage may be true, researchers also acknowledge that substance use among women has been a hidden issue, one not realistically acknowledged by society, especially prior to the mid-1960s. Along with this, more recent data indicates that rates of substance use among women are increasing. Factors contributing to this increase in substance abuse have begun to receive considerable attention, and recent research suggests that many issues exist that are unique to substance use among women. The purpose of this article is to discuss gender specific considerations in women's substance abuse by examining the history of substance use among women; analyzing gender-specific factors, including physiological factors, trauma-related factors, mental health issues, and cultural considerations that impact on women's substance use; articulating treatment approaches for working with substance abusing women and girls; and providing recommendations for further research in this area.

  6. The Impact of Gender Segregation on Male-Female Wage Differentials

    Amuedo Dorantes, Catalina; De la Rica Goiricelaya, Sara

    2005-01-01

    This paper presents new evidence on the role of gender segregation and pay structure in explaining gender wage differentials of full-time salaried workers in Spain. Data from the 1995 and 2002 Wage Structure Surveys reveal that raw gender wage gaps decreased from 0.24 to 0.14 over the seven-year period. Average differences in the base wage and wage complements decreased from 0.09 to 0.05 and from 0.59 to 0.40, respectively. However, the gender wage gap is still large after accounting for work...

    Reliable and high-resolution reference data for regional cerebral blood flow measured with single-photon emission tomography (SPET) are necessary for optimal clinical and research use. Therefore, a large dataset of normal technetium-99m labelled ethylene cysteine dimer (ECD) perfusion SPET in carefully screened healthy volunteers with an age range spanning six decades was created, with correction for non-uniform attenuation and scatter and based on an anatomically standardised analysis. Eighty-nine healthy volunteers, stratified for gender (46 females, 43 males; age 20-81 years), were included. Twelve volunteers underwent repeated {sup 99m}Tc-ECD SPET after 2.5{+-}2.3 weeks. An automated whole-brain volume of interest analysis with MANOVA as well as voxelwise analysis using SPM99 was conducted. Average intersubject variability was 4.8% while intrasubject reproducibility was 3.0%. An age-related decline in tracer uptake was found in the anterior cingulate gyrus, bilateral basal ganglia, left prefrontal, left lateral frontal and left superior temporal and insular cortex (all P=0.001-0.02). There was an overall increase in right/left asymmetry with age, which was most pronounced in the frontal and temporal neocortex. The most significant correlations between AI and age decade were found in the prefrontal (R=0.35, P=0.001) and superior temporal neocortex (R=0.43, P<0.001). Women had significantly higher uptake in the right parietal cortex (P<0.001), while men showed higher uptake in the cerebellum and the left anterior temporal and orbitofrontal cortex (all P<0.01). This normative dataset allows age- and gender-specific patient and group assessment of {sup 99m}Tc-ECD perfusion SPET under a wide variety of clinical circumstances in relation to normal variations and highlights the importance of both age- and gender-specific normal datasets for optimal analysis sensitivity.

    Although many studies have suggested social participation (SP) has beneficial effects on elderly people's health, most of them failed to deal with paid work. Additionally, few studies have focused on the age effect between SP and older people's health. To investigate whether the association between SP, including paid work, and instrumental activities of daily living (IADL), exhibits not only in gender, but also in age among community-dwelling older adults. In 2014, we distributed self-administered questionnaires to all community-dwelling elderly aged ≥65 in two medium-sized cities in Nara Prefecture, Japan (n = 32,825). 22,845 residents submitted the questionnaire (response rate, 69.6%). Analyzed subjects were limited to 17,680 persons who had neither dependency in basic ADL nor missing data for required items. SP was assessed based on participation frequency in seven types of social activities: volunteer groups, sports groups, hobby groups, cultural groups, senior citizens' clubs, neighborhood community associations, and paid work. Using Poisson regression models, prevalence ratio for poor IADL was calculated. To examine age and gender differences in the association between SP and IADL, we performed stratified analyses by age and gender group; male young-old (aged 65-74), male old-old (aged ≥75), female young-old, and female old-old. Prevalence of those with poor IADL was 17.1% in males and 4.5% in females, showing a significant gender difference. After adjustment for relevant covariates, volunteer groups were inversely associated with poor IADL only in males and the relationship was stronger in the old-old group than in the young-old group. Conversely, only females had a significant inverse association between paid work and poor IADL, and the association was not reliant on their ages but only those who participated infrequently had a favorable effect. Influence of age in the beneficial association between SP and IADL was generally larger in the old

    A cross sectional study was carried out (impetigo cases n=265, relative prevalence 5.3%, among 50,237 outpatients). Males predominated in childhood, adulthood and overall (OR 2.0) and exhibited a more protracted susceptibility. Impetigo was more prevalent in summer months. Lesions were located on the head and neck (65.4%), followed by 19.6% on an upper extremity and by 7.5% each on the trunk and a lower extremity.

    The scope of this study was to construct an indicator of active aging and assess its association with quality of life and possible determinants according to gender. The AGEQOL (Aging, Gender and Quality of Life) study was used to interview 2052 individuals aged 60 years and older residing in Sete Lagoas in the State of Minas Gerais. The association between active aging, quality of life and possible determinants was performed by multiple logistic regression with a 5% level of statistical significance separately for each gender. Most men were in the active aging group (58%), and 51.8% of women were in the normal aging group (p active aging. Women with higher incomes, who did not suffer falls and engaged in community participation, had a better chance of belonging to the active aging group. The conclusion drawn is that quality of life and participation in groups are the main determinants of active aging, and the other factors associated with active aging are different for each gender.

    Initial pain level in the acute whiplash injury is the most consistent predictor of transformation to a chronic pain syndrome. The risk factors for those early pain levels were, to our knowledge, scarcely evaluate to this date. We set to evaluate whether gender, age or ethnicity comprise a risk factor for those initial pain levels. Further, gender, age and ethnicity have been shown to be bias factors in pain management. We investigated if gender, age or ethnicity are bias factor in pain management in the face of a standardized pain treatment protocol in the acute whiplash injury. We reviewed 2,538 patients with acute whiplash injury that were treated at our emergency department (ED). Gender, age and ethnicity were investigated as risk factors for elevated visual analog scale (VAS) scores. Those factors were also investigated as bias in pain medication administration in the face of a standardized analgesic protocol. Women had significantly higher VAS scores (p = 0.009). Age and ethnicity did not influence pain levels. There was no influence of gender or age on pain medication administration. The Jewish patients (the majority in Israel) were administered fewer pain medication (p whiplash injury. Age and ethnicity have less impact on those pain levels. A pain management protocol might reduce bias in pain management in the acute whiplash injury in the ED. The Jewish population tends to be less receptive to pain medication administration.

    School-based athletic programs remain an important context for violence prevention efforts although a better understanding of how gender attitudes and abuse perpetration differ among athletes is needed. We analyzed baseline survey data from the "Coaching Boys into Men" study-a school-based cluster-randomized trial in 16 high schools in Northern California. We describe relationships among gender-inequitable attitudes, sport type, and recent adolescent relationship abuse perpetration among a sample of male athletes (n = 1,648). Gender-inequitable attitudes (adjusted odds ratio (AOR), 3.26; 95% confidence interval (CI), 2.56, 4.15), participation in both high school football and basketball (AOR, 2.08; 95% CI, 1.37, 3.18), and participation in football only (AOR, 1.50; 95% CI, 1.02, 2.22) emerged as independently associated with recent ARA perpetration. Findings warrant targeted violence prevention efforts among male high school athletes that incorporate discussions of gender attitudes and healthy relationships, especially among sports teams at greater risk of adolescent relationship abuse perpetration.

  15. Male chimpanzees' grooming rates vary by female age, parity, and fertility status.

    Copulation preferences in our closest living relative, the chimpanzee, suggest that males prefer older females who have had previous offspring. However, this finding is counter to some behavioral models, which predict that chimpanzee males, as promiscuous breeders with minimal costs to mating, should show little or no preference when choosing mating partners (e.g. should mate indiscriminately). To determine if the preferences indicated by copulations appear in other contexts as well as how they interact, we examined how male chimpanzees' grooming patterns varied amongst females. We found that males' preferences were based on interactions among females' fertility status, age, and parity. First, grooming increased with increasing female parity. We further found an effect of the estrous cycle on grooming; when females were at the lowest point of their cycle, males preferentially groomed parous females at peak reproductive age, but during maximal tumescence, males preferred the oldest multiparous females. Nulliparous females received relatively little grooming regardless of age or fertility. Thus, male chimpanzees apparently chose grooming partners based on both female's experience and fertility, possibly indicating a two-pronged social investment strategy. Male selectivity seems to have evolved to effectively distribute costly social resources in a pattern which may increase their overall reproductive success. © 2011 Wiley-Liss, Inc.

    Placental insufficiency programs an increase in blood pressure associated with a twofold increase in serum testosterone in male growth-restricted offspring at 4 mo of age. Population studies indicate that the inverse relationship between birth weight and blood pressure is amplified with age. Thus, we tested the hypothesis that intrauterine growth restriction programs an age-related increase in blood pressure in male offspring. Growth-restricted offspring retained a significantly higher blood pressure at 12 but not at 18 mo of age compared with age-matched controls. Blood pressure was significantly increased in control offspring at 18 mo of age relative to control counterparts at 12 mo; however, blood pressure was not increased in growth-restricted at 18 mo relative to growth-restricted counterparts at 12 mo. Serum testosterone levels were not elevated in growth-restricted offspring relative to control at 12 mo of age. Thus, male growth-restricted offspring no longer exhibited a positive association between blood pressure and testosterone at 12 mo of age. Unlike hypertension in male growth-restricted offspring at 4 mo of age, inhibition of the renin-angiotensin system with enalapril (250 mg/l for 2 wk) did not abolish the difference in blood pressure in growth-restricted offspring relative to control counterparts at 12 mo of age. Therefore, these data suggest that intrauterine growth restriction programs an accelerated age-related increase in blood pressure in growth-restricted offspring. Furthermore, this study suggests that the etiology of increased blood pressure in male growth-restricted offspring at 12 mo of age differs from that at 4 mo of age. PMID:27147668

  17. Canine length in wild male baboons: maturation, aging and social dominance rank.

    Jordi Galbany

    Full Text Available Canines represent an essential component of the dentition for any heterodont mammal. In primates, like many other mammals, canines are frequently used as weapons. Hence, tooth size and wear may have significant implications for fighting ability, and consequently for social dominance rank, reproductive success, and fitness. We evaluated sources of variance in canine growth and length in a well-studied wild primate population because of the potential importance of canines for male reproductive success in many primates. Specifically, we measured maxillary canine length in 80 wild male baboons (aged 5.04-20.45 years from the Amboseli ecosystem in southern Kenya, and examined its relationship with maturation, age, and social dominance rank. In our analysis of maturation, we compared food-enhanced baboons (those that fed part time at a refuse pit associated with a tourist lodge with wild-feeding males, and found that food-enhanced males achieved long canines earlier than wild-feeding males. Among adult males, canine length decreased with age because of tooth wear. We found some evidence that, after controlling for age, longer canines were associated with higher adult dominance rank (accounting for 9% of the variance in rank, but only among relatively high-ranking males. This result supports the idea that social rank, and thus reproductive success and fitness, may depend in part on fighting ability mediated by canine size.

  18. Influence of maternal age, gestational age and fetal gender on expression of immune mediators in amniotic fluid

    Weissenbacher Tobias

    2012-07-01

    Full Text Available Abstract Background Variations in cytokine and immune mediator expression patterns in amniotic fluid due to gestational age, maternal age and fetal gender were investigated. Findings Amniotic fluid samples were obtained from 192 women, 82 with a mid-trimester amniocentesis (median gestational age 17 weeks and 110 with a caesarean section not in labor (median gestational age 39 weeks. Amniotic fluid was screened by commercial ELISAs for the TH1/TH2/TH17 cytokines and immune mediators IL-1 beta, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-15, IL-17, TNF alpha, GRO-alpha, MIP1alpha, MIP1beta, Histone, and IP10. Analysis was by Bonferroni correction for multiple comparisons. None of the 15 examined cytokines revealed any differences in expression patterns regarding fetal gender. Significant differences were found in IL-4, IL-10, IL-12, TNF- alpha, GRO-alpha and MIP1-beta with respect to gestational age and in GRO-alpha regarding maternal age. Conclusion Cytokines utilized as biomarkers in the diagnosis of intrauterine infections are not influenced in their expression pattern by fetal gender but may vary with respect to maternal age and gestational age.

    The aim of this study was to determine age, gender, and hemispheric differences in the volume of the human neostriatum (striatum) nucleus in healthy humans. This study was performed on 120 normal human subjects (60 males, 60 females, right-handed) 15–65 years old, divided into two groups: young (<40 yrs) and old (=≥40 yrs). Sectional brain images were obtained via magnetic resonance imaging (MRI), analyzed and processed using the Image-J software, and the striatum volume was calculated using the Cavalieri’s principle, retrospectively. The analyses revealed bilateral age-related shrinkage of the putamen in both genders and the putamen and caudate nucleus were significantly smaller in older than in younger subjects (P-value <0.001). The age-related shrinkage of the caudate and putamen nucleus in men and women was about 5%, 5% and 4%, 4%, respectively, and there were statistically significant volume differences between males and females (P-value <0.05). In both genders, a significant rightward asymmetry was observed in the caudate and putamen nucleus (3.89%, 4.21% in men and 4.51%, 3.32% in women). Bilateral age-related shrinkage and rightward asymmetry of the striate nucleus was found in healthy adults and there were significant volume differences between men and women. Obtained results provide useful baseline data on age and gender-related changes of the volume of the striatum

    We hypothesized that recent hands-on practice for cardiopulmonary resuscitation (CPR) would be strongly associated with a higher likelihood of self-efficacy in bystander CPR among laypersons according to age and gender group. We used the National Korean Community Health Survey database of 228921 representatively sampled responders from 253 counties in 2012. Laypersons who had previous CPR training were eligible. Exposure variables were having had CPR training with hands-on practice session with a manikin (Practical-CPR-Training) and CPR training within the last 2 years (Recent-CPR-Training). Primary outcome was self-efficacy in bystander CPR. Multivariable logistic regression analysis was performed. The final model with an interaction term was evaluated to compare the effects of CPR training across different age and gender groups. Of 62425 eligible respondents who have had CPR training, 20213 (32.4%) had Practical-CPR-Training. Adjusted odds ratios (AORs) for self-efficacy were 4.08 (3.78-4.41) in Practical-CPR-Training, 2.61 (2.50-2.73) in male, 1.26 (1.16-1.36) in good self-rated health, 1.19 (1.10-1.29) in high school graduate, 1.19 (1.01-1.39) in persons living with stroke patients in household, and 1.17 (1.10-1.24) in Recent-CPR-Training. In interaction models, Practical-CPR-Training showed higher self-efficacy in all age and gender groups, whereas Recent-CPR-Training was not associated with better self-efficacy in elderly group, male (AOR, 0.90 [0.69-1.18]) and female (AOR, 0.94 [0.72-1.23]). Self-efficacy in bystander CPR was higher in person with recent CPR training with hands-on practice with a manikin. Copyright © 2015 Elsevier Inc. All rights reserved.
