Research examining the impact on adolescent boys of exposure to muscular, athletic, idealised male images has been limited. This research had two aims (i) to investigate the mean effect on state body satisfaction and mood of exposure to idealised male images in adolescent boys, and, (ii) to identify individual attributes that predicted change in state body satisfaction, depression and anxiety following image exposure. One hundred and six boys (mean age=15.6 years) completed a self-report questionnaire on body image attitudes and psychological status. One week later, participants were divided into two groups, one that viewed idealised male images (experimental condition) while the other viewed non-figure advertising images (control condition). Three body satisfaction Visual Analogue Scale (VAS), and a depression and anxiety VAS were completed immediately prior to and following image exposure. In the experimental compared to control condition, there were no significant changes on Want Toned Body, Want to Change Body Shape, Depression and Anxiety VAS following image exposure. However, there was a significant improvement in Like Body Shape VAS. In the experimental group, high internalisation of the muscular, athletic ideal predicted more negative response to viewing images on the body image and Depression VAS. Prior body dissatisfaction significantly predicted negative response to Body Shape Liking and Anxiety VAS. While on average, adolescent boys in this research were not negatively affected by exposure to idealised male images, reaction to exposure is dependent on individual attributes.
Full Text Available This study investigated possible differences using the same stretch-shortening exercise (SSE protocol on generally accepted monitoring markers (dependent variables: changes in creatine kinase, muscle soreness, and voluntary and electrically evoked torque in males across three lifespan stages (childhood versus adulthood versus old age. The protocol consisted of 100 intermittent (30 s interval between jumps drop jumps to determine the repeated bout effect (RBE (first and second bouts performed at a 2-week interval. The results showed that indirect symptoms of exercise-induced muscle damage after SSE were more expressed in adult males than in boys and elderly males, suggesting that the muscles of boys and elderly males are more resistant to exercise-induced damage than those of adult males. RBE was more pronounced in adult males than in boys and elderly males, suggesting that the muscles of boys and elderly males are less adaptive to exercise-induced muscle damage than those of adult males.

The purpose of this article is to describe a "male-friendly" therapeutic process with troubled adolescent boys. A male-friendly process is one in which the therapist employs a wide variety of strategies and activities that are likely to appeal to male youth and that facilitate the establishment and maintenance of rapport. The nuances of practicing a male-friendly approach are highlighted and then applied in a case study of psychotherapy with a depressed adolescent boy. The implications of this approach for redefining professional conceptions about boundaries in the client-therapist relationship and reexamining inaccurate stereotypes about the emotional lives of boys are discussed.

Relatively unexplored by research is how young boys transact and respond to literacy experiences during read-alouds. Some teachers perceive boys to be less interested in literacy and to prefer different kinds of stories than young girls. The purpose of this study was to analyze how two groups of preschool boys responded to different texts and how…

To explore parents' views of extending the human papillomavirus (HPV) vaccination programme to also include boys. Explorative qualitative design using individual, face-to-face, interviews and inductive thematic analysis. 11 strategically chosen municipalities in central Sweden. Parents (n=42) who were offered HPV vaccination for their 11-12 years old daughter in the national school-based vaccination programme. The key themes were: equality from a public health perspective and perception of risk for disease . Parents expressed low knowledge and awareness about the health benefits of male HPV vaccination, and they perceived low risk for boys to get HPV. Some parents could not see any reason for vaccinating boys. However, many parents preferred gender-neutral vaccination, and some of the parents who had not accepted HPV vaccination for their daughter expressed that they would be willing to accept vaccination for their son, if it was offered. It was evident that there was both trust and distrust in authorities' decision to only vaccinate girls. Parents expressed a preference for increased sexual and reproductive health promotion such as more information about condom use. Some parents shared that it was more important to vaccinate girls than boys since they believed girls face a higher risk of deadly diseases associated with HPV, but some also believed girls might be more vulnerable to side effects of the vaccine. A vaccine offered only to girls may cause parents to be hesitant to vaccinate, while also including boys in the national vaccination programme might improve parents' trust in the vaccine. More information about the health benefits of HPV vaccination for males is necessary to increase HPV vaccination among boys. This may eventually lead to increased HPV vaccine coverage among both girls and boys. Published by the BMJ Publishing Group Limited.

Full Text Available Cryptorchidism is the most common congenital birth defect in boys and affects about 2–4% full-term male neonates. Its etiology is multifactorial. Purpose. To evaluate the serum bisphenol A (BPA levels in boys with cryptorchidism and healthy boys and to assess the risk of environmental exposure to BPA using the authors’ questionnaire. The data were acquired from a study on boys with cryptorchidism (n=98 and a control group (n=57. Prior to surgery, all patients had BPA serum levels evaluated. The size, position, rigidity of the testis, and abnormality of the epididymis of the undescended testis were assessed. Parents also completed a questionnaire on the risks of exposure to BPA in everyday life. Results. The testes in both groups were similar in size. The turgor of the undescended testis in the group of boys with cryptorchidism was decreased. Free serum BPA level in cryptorchid boys and in the control group was not statistically significant (p>0.05. The conjugated serum BPA level in cryptorchid boys and in the control group was statistically significant (p≤0.05. Total serum BPA level in cryptorchid boys and in the control group was statistically significant (p<0.05. Serum total BPA level was related with a positive answer about problems with conception (p<0.02. Conclusion. Our study indicated that high serum BPA was associated with cryptorchidism.
In the discourse on health, boys are emerging as a problem group. In contrast to girls who tended to be seen as fragile if not sickly, boys used to be thought of as strong and healthy. Gender-specific concepts stipulated much more exercise for boys, the masturbation discourse prevented a relaxed relationship to the own body. The paper first describes specific problems in the biography (babies, child labour, tuberculosis, school, fitness for military service) and their solutions up to the time of the Weimar Republic. During and after the two world wars school boys tended to be of poorer health than girls. The consequences of war affect the mental health of (half-) orphans gender-non-specifically up to the third generation. After 1945, attention to health concerns is rather restricted to the professional aptitude of mining trainees, health-related risk behaviour tends to be interpreted in terms of gender. Mothers sought medical advice slightly more frequently on behalf of boys up to puberty. Concerning the time between 1780 and 2010 inferior health is often noticeable in boys and male adolescents. This used to, and still does, apply to babies, child labour, industrial work and occupational accidents, conscription and direct consequences of war. It was mostly due to gender-specific separation of labour, but partly also to a higher risk preference. The gender-specific wider scope for exercise and sports up to the 1960s, in contrast, had a health-promoting effect.

With girls having overtaken boys in many education indicators, the 'feminization' of elementary school teaching is causing debates about disadvantages for male students. Using administrative panel data on the universe of students, teachers and schools for a German state, I exploit within school and within teacher variation to determine teacher characteristics' effects on students' tracking outcomes. Germany tracks students at age 10 into more or less academic school types. I find hardly any e...

Sport is highly relevant in the life of boys and young men. It is not only one of the most common and important leisure activities, but also helps male self-assurance through physical conflicts and competitions as well as through physical proximity and social involvement. At the same time, sport is an ambivalent area that preserves health, but can also be dangerous to it. By considering the development of male identity, the specific possibilities of sport, as well as an overview of the health situation of boys, this article develops starting points for lifestyle-oriented health promotion of boys and young men in the area of exercise, games and sport. In sports, physical practices are learned that can have long-term effects as somatic cultures on health behavior. The work with boys in sports can be health-promoting if opportunities and risks are reflected upon and considered in the didactic planning and execution.

Full Text Available The aim of the study was to examine differences in total body water (TBW measured using single-frequency (SF and multi-frequency (MF modes of bioelectrical impedance spectroscopy (BIS in children and adults measured in different postures using the deuterium (2H dilution technique as the reference. Twenty-three boys and 26 adult males underwent assessment of TBW using the dilution technique and BIS measured in supine and standing positions using two frequencies of the SF mode (50 kHz and 100 kHz and the MF mode. While TBW estimated from the MF mode was comparable, extra-cellular fluid (ECF and intra-cellular fluid (ICF values differed significantly (p < 0.01 between the different postures in both groups. In addition, while estimated TBW in adult males using the MF mode was significantly (p < 0.01 greater than the result from the dilution technique, TBW estimated using the SF mode and prediction equation was significantly (p < 0.01 lower in boys. Measurement posture may not affect estimation of TBW in boys and adult males, however, body fluid shifts may still occur. In addition, technical factors, including selection of prediction equation, may be important when TBW is estimated from measured impedance.

Male circumcision is practiced in South Africa among the Xhosa people as a rite of passage from boyhood to manhood. The manhood status achieved after the ritual accords men power and authority in the community over women and uncircumcised men. Therefore, uninitiated men experience great pressures to get circumcised. We describe the experience of newly initiated Xhosa men in East London, South Africa. Interpretive phenomenology was used as the inquiry of choice. Data were collected through focus group discussions in which 14 men participated. The theme of marginalization of uninitiated Xhosa males emerged with two categories: (a) rejection, and (b) lack of respect. The participants revealed that uninitiated men are rejected by the community, their own families, friends, and women. We frame the discussion around the concept of stigma. Acknowledging that uninitiated males are stigmatized can help mitigate stigma, and in turn, the incidence of medical complications from botched circumcisions.
Studies of physical education teacher training have already established that hegemonic forms of masculinity are reinforced and reproduced both in the hidden curriculum (Flintoff, 1997) and the informal student culture (Skelton, 1993). Given this, an important feminist concern is whether male PE teachers whose own masculine identities are anchored…

Full Text Available Sexual harassment has been widely studied in the workforce, but the factors that contribute to hostile educational environments for women have received less attention. The present study focuses on male dominance, gender harassment, gender threats, masculinity, and their influences on creating a hostile environment for women in academia. One hundred and forty-two male participants from a private university in the Southwestern United States self-reported their masculinity, completed a group task with a female confederate leader serving as a gender threat in half the conditions, and had their subsequent affect, perceptions of leadership effectiveness, and behavioral aggression measured. Men from male-dominated majors and men who had received a gender threat did not differ from men from gender-equivalent majors and men who had not received a gender threat on affect, perceptions of leadership effectiveness, or behavioral aggression (ps > 0.201, ηp2s ≤ 0.007. However, post-hoc analyses revealed that as masculinity increased among men from male-dominated majors under gender threat, they became significantly more behaviorally aggressive (b = 5.92, p = 0.003 and perceived their female leader as less effective (b = −0.83, p = 0.076. Implications and suggestions for future research are discussed.

Men's perpetration of gender-based violence remains a global public health issue. Violence prevention experts call for engagement of boys and men to change social norms around masculinity in order to prevent gender-based violence. Yet, men do not comprise a homogenous category. Drawing on probability estimates of men who report same-sex practices and preferences captured in a multi-country gender-based violence prevention survey in the Asia-Pacific region, we test the effects of sexuality-related factors on men's adverse life experiences. We find that sexual minority men face statistically higher risk of lifetime adversity related to gender-based violence, stemming from gender inequitable norms in society. Sexuality is thus a key axis of differentiation among men in the Asia-Pacific region, influencing health and wellbeing and reflecting men's differential engagement with dominant norms of masculinity. Integrating awareness of male sexual diversity into gender-based violence prevention interventions, particularly those that work with boys and men, and bridging violence prevention programming between sexual minority communities and women, are essential to tackle the root drivers of violence.

Infertility affects an estimated 15% of couples globally, amounting to 48.5 million couples. Males are found to be solely responsible for 20-30% of infertility cases and contribute to 50% of cases overall. However, this number does not accurately represent all regions of the world. Indeed, on a global level, there is a lack of accurate statistics on rates of male infertility. Our report examines major regions of the world and reports rates of male infertility based on data on female infertility. Our search consisted of systematic reviews, meta-analyses, and population-based studies by searching the terms "epidemiology, male infertility, and prevalence." We identified 16 articles for detailed study. We typically used the assumption that 50% of all cases of infertility are due to female factors alone, 20-30% are due to male factors alone, and the remaining 20-30% are due to a combination of male and female factors. Therefore, in regions of the world where male factor or rates of male infertility were not reported, we used this assumption to calculate general rates of male factor infertility. Our calculated data showed that the distribution of infertility due to male factor ranged from 20% to 70% and that the percentage of infertile men ranged from 2·5% to 12%. Infertility rates were highest in Africa and Central/Eastern Europe. Additionally, according to a variety of sources, rates of male infertility in North America, Australia, and Central and Eastern Europe varied from 4 5-6%, 9%, and 8-12%, respectively. This study demonstrates a novel and unique way to calculate the distribution of male infertility around the world. According to our results, at least 30 million men worldwide are infertile with the highest rates in Africa and Eastern Europe. Results indicate further research is needed regarding etiology and treatment, reduce stigma & cultural barriers, and establish a more precise calculation.

Male circumcision (MC) significantly reduces HIV acquisition among men, leading WHO/UNAIDS to recommend high HIV and low MC prevalence countries circumcise 80% of adolescents and men age 15-49. Despite significant investment to increase MC capacity only 27% of the goal has been achieved in Zimbabwe. To increase adoption, research to create evidence-based messages is greatly needed. The Integrated Behavioral Model (IBM) was used to investigate factors affecting MC motivation among adolescents. Based on qualitative elicitation study results a survey was designed and administered to a representative sample of 802 adolescent boys aged 13-17 in two urban and two rural areas in Zimbabwe. Multiple regression analysis found all six IBM constructs (2 attitude, 2 social influence, 2 personal agency) significantly explained MC intention (R 2 = 0.55). Stepwise regression analysis of beliefs underlying each IBM belief-based construct found 9 behavioral, 6 injunctive norm, 2 descriptive norm, 5 efficacy, and 8 control beliefs significantly explained MC intention. A final stepwise regression of all the significant IBM construct beliefs identified 12 key beliefs best explaining intention. Similar analyses were carried out with subgroups of adolescents by urban-rural and age. Different sets of behavioral, normative, efficacy, and control beliefs were significant for each sub-group. This study demonstrates the application of theory-driven research to identify evidence-based targets for the design of effective MC messages for interventions to increase adolescents' motivation. Incorporating these findings into communication campaigns is likely to improve demand for MC.

Many psychologists assert that boys are in dire straits in U.S. society, but in fact, there is no evidence of an emotional or behavioral epidemic for either sex. If there is any truth to the claim that boys are in trouble, it results from practices that foster aggression. It is a mistake to regard either gender as "fragile." (SLD)
The author traces the course taken by psychoanalytically oriented feminist film theory from its beginnings in the late seventies. She situates its origins in the Anglo-American debate about the exclusion of female subjectivity from the cinema and the new awareness of the problem of the cinematic mise-en-scène of the gaze, of "visual pleasure". First, massive criticism was levelled at the exclusively male/patriarchal gaze of the viewer, then emphasis centred around the specifically female gaze as a category in aesthetic theory. Ultimately, psychoanalytic feminist film theory has turned its attention to films for women, melodrams and early movies in an attempt to capture the respective historical forms of female subjectivity that they reflect.

Investigates the relationship of personality and past film viewing experiences to preferences for different degrees of graphic horror in film, and for female versus male victimization. Finds that the Machiavellian trait of deceit, past exposure to horror films, and, for male subjects only, the enjoyment of pornography were good predictors. (SR)

To study associations between crime and psychiatric disorders among adolescent males in a representative population-based cohort study. The sample includes 2,712 Finnish boys born in 1981. Information on criminality consists of offenses registered in the Finnish National Police Register 1998-2001. Crime was classified according to frequency and type (drug, violent, property, traffic, and drunk driving offenses). Information on psychiatric diagnoses between 1999 and 2004 was collected from the Finnish National Military Register. Of the 2,712 boys, 22% had a crime registration during the 4-year period, and 10% had at least one psychiatric disorder according to the Military Register. Those with psychiatric disorders accounted for 49% of all crimes. Of those with more than five crimes (n = 98), 59% had psychiatric diagnoses. After adjusting for other crime types and childhood socio-economic status, property crime was independently associated with several diagnoses: antisocial personality (APD), substance use (SUD), psychotic, anxiety, and adjustment disorders. Drug offending was independently associated with APD, SUD, and psychotic disorder, and traffic offenses with APD. Youth crime is predominantly associated with antisocial personality and substance use disorders. Crime prevention efforts should focus on boys showing a risk for antisocial and substance use problems. In particular, property, drug, and repeat offenders need mental health and substance use assessment. There is a need to develop integrated mental health and substance use treatment services for young offenders within or alongside the criminal justice system.
Full Text Available Abstract Background Pontocerebellar hypoplasia (PCH is a heterogeneous group of diseases characterized by lack of development and/or early neurodegeneration of cerebellum and brainstem. According to clinical features, seven subtypes of PCH have been described, PCH type 2 related to TSEN54 mutations being the most frequent. PCH is most often autosomal recessive though de novo anomalies in the X-linked gene CASK have recently been identified in patients, mostly females, presenting with intellectual disability, microcephaly and PCH (MICPCH. Methods Fourteen patients (12 females and two males; aged 16 months-14 years presenting with PCH at neuroimaging and with clinical characteristics unsuggestive of PCH1 or PCH2 were included. The CASK gene screening was performed using Array-CGH and sequencing. Clinical and neuroradiological features were collected. Results We observed a high frequency of patients with a CASK mutation (13/14. Ten patients (8 girls and 2 boys had intragenic mutations and three female patients had a Xp11.4 submicroscopic deletion including the CASK gene. All were de novo mutations. Phenotype was variable in severity but highly similar among the 11 girls and was characterized by psychomotor retardation, severe intellectual disability, progressive microcephaly, dystonia, mild dysmorphism, and scoliosis. Other signs were frequently associated, such as growth retardation, ophthalmologic anomalies (glaucoma, megalocornea and optic atrophy, deafness and epilepsy. As expected in an X-linked disease manifesting mainly in females, the boy hemizygous for a splice mutation had a very severe phenotype with nearly no development and refractory epilepsy. We described a mild phenotype in a boy with a mosaic truncating mutation. We found some degree of correlation between severity of the vermis hypoplasia and clinical phenotype. Conclusion This study describes a new series of PCH female patients with CASK inactivating mutations and confirms that

The enzyme steroid sulfatase (STS) converts sulfated steroids to their non-sulfated forms. Deficiency for this enzyme is associated with inattention but preserved response control. The polymorphism rs17268988 within the X-linked STS gene is associated with inattentive, but not other, symptoms in boys with attention deficit hyperactivity disorder (ADHD). We initially tested whether rs17268988 genotype was associated with attention, response control, and underlying aspects of cognition, using questionnaires and neuropsychological tasks, in two independent cohorts of healthy adult males. In an additional analysis based upon existing data, the performance of mice with genetic or pharmacological manipulations of the STS axis under attentionally demanding conditions was investigated. G-allele carriers at rs17268988 exhibited reduced reaction time, enhanced attention, and reduced reaction time variability relative to C-allele carriers. Mice with genetic or pharmacological manipulations of the STS axis were shown to have perturbed reaction time variability. Our findings provide additional support for an association between rs17268988 genotype and attention, which may be partially mediated by reaction time variability; they also indicate that, in contrast to the situation in boys with ADHD, in healthy men, the G-allele at rs17268988 is associated with enhanced cognition. As reaction time variability is a predictor of well-being, rs17268988 genotype may represent a biomarker for long-term health.
Seeking to understand the highly unfavorable conditions for the development of gay male theater in Sweden, this essay engages in a historical study of the national opening of Mart Crowley's The Boys in the Band at Malmö City Theatre in 1970. Propelled by a Foucauldian-inspired theoretical approach, it identifies the subtle, yet highly effective, measures of control that the, at the time, social democratic welfare state exercised over representations of homosexuality on stage. State representatives, who complied with the official political and medical doctrine that homosexuality was a mental illness and posed a potential threat to social stability, interfered at various levels of the production, including the rehearsal process and post-performance talks between cast members and audiences. This alliance between Swedish theaters and members of the medical, psychological, and sexological professions constituted a medico-artistic complicity that supervised and regulated early attempts of gay representation on stage.

Sexual reference display on a social networking web site (SNS) is associated with self-reported sexual intention; females are more likely to display sexually explicit content on SNSs. The purpose of this study was to investigate male college students' views towards sexual references displayed on publicly available SNSs by females. Focus groups. One large state university. Male college students age 18-23. All tape recorded discussion was fully transcribed, then discussed to determine thematic consensus. A trained male facilitator asked participants about views on sexual references displayed on SNSs by female peers and showed examples of sexual references from female's SNS profiles to facilitate discussion. A total of 28 heterosexual male participants participated in seven focus groups. Nearly all participants reported using Facebook to evaluate potential female partners. Three themes emerged from our data. First, participants reported that displays of sexual references on social networking web sites increased sexual expectations. Second, sexual reference display decreased interest in pursuing a dating relationship. Third, SNS data was acknowledged as imperfect but valuable. Females who display sexual references on publicly available SNS profiles may be influencing potential partners' sexual expectations and dating intentions. Future research should examine females' motivations and beliefs about displaying such references and educate women about the potential impact of these sexual displays.

There is limited research that has examined experimentally the effects of muscular images on adolescent boys' body image, with no research specifically examining the effects of music television. The aim of the current study was to examine the effects of viewing muscular and attractive singers in music video clips on early, mid, and late adolescent boys' body image, mood, and schema activation. Participants were 180 boys in grade 7 (mean age = 12.73 years), grade 9 (mean age = 14.40 years) or grade 11 (mean age = 16.15 years) who completed pre- and post-test measures of mood and body satisfaction after viewing music videos containing male singers of muscular or average appearance. They also completed measures of schema activation and social comparison after viewing the clips. The results showed that the boys who viewed the muscular clips reported poorer upper body satisfaction, lower appearance satisfaction, lower happiness, and more depressive feelings compared to boys who viewed the clips depicting singers of average appearance. There was no evidence of increased appearance schema activation but the boys who viewed the muscular clips did report higher levels of social comparison to the singers. The results suggest that music video clips are a powerful form of media in conveying information about the male ideal body shape and that negative effects are found in boys as young as 12 years.

A clinical case is provided as an illustration of this article.
Full Text Available The role of teachers in affecting students’ attitudes and motivations to language learning and teaching cannot be denied. To improve the field of foreign language teaching and learning we need to improve the qualities of EFL teachers. To achieve this goal, recognizing and identifying the qualities of effective EFL teachers is essential. So this study attempted to investigate the view points of male and female English language students about the characteristics of effective English language teachers based on four categories: English proficiency, pedagogical knowledge, organization and communication skills, and socio-affective skills. For this purpose the researchers administered a questionnaire adapted from Park and Lee (2006 to 60 (28 female and 32 male foreign language learners at Tabriz Islamic Azad University. The results of the U-Mann-Whitney test indicated that there was not a significant difference between the perceptions of the male and female students regarding the characteristics of effective teacher. However, the overall mean score of the female students’ perceptions was a little bit higher than the male students. For the female students the most important features of the teacher was his/her English proficiency, socio-affective skills, pedagogical knowledge and organization and communication skills, while the preferences of the male students were the organization and communication skills, pedagogical knowledge, socio-affective skills and English proficiency, respectively. The findings have some implications for EFL teachers and students.

Teenagers have very particular needs and their healthcare must be adapted to these needs. Despite all the modern means of communication and education, problems related to sex and sexuality have an effect on their well-being. Sex education has improved in the last 40 years, but what is today's situation? In the Maine-et-Loire region of France, approximately 100 15- to 16-year-olds responded to a questionnaire, giving their views on the nature and quality of the sexual and emotional education they received. It appears that it falls very short of the legal requirements and that it is often inappropriate to the needs of young people. To improve sexual prevention, it is necessary to start early to provide sexual and emotional education and to increase the opportunities and the diversity of speakers presenting themes of importance to young people. The speaker should preferably be young and use lively means of communication and role-plays to normalize sex education. The most important aspects are respecting this young population as well as opening and maintaining communication with them, which will help them make better choices toward a better future. Promoting sex education is part of a global approach to healthy lifestyles and requires a national strategy, cooperation between the interested parties, and an adequate budget.

Full Text Available Background: Male partners have a strong influence on pregnant partners’ health and their access to care. Their involvement is critical in the delivery and uptake of maternal healthcare services and improving maternal and child health outcomes. Aim: The study sought to determine male partners’ views on their involvement in maternal healthcare services. Setting: The Makhado Municipality’s Kutama, Madombidzha and Vleifontein clinics. Methods: A qualitative study design, which is exploratory, descriptive and contextual in nature, was used. The population comprised 15 men whose partners had been pregnant within the last 2 years. A non-probability, purposive sampling procedure was used. Data were collected via in-depth individual interviews using a voice recorder and an interview schedule guide. Tesch’s open coding method was used to analyse data. Results: The findings revealed one major theme, namely that maternal health issues are viewed as a woman’sdomain; and three sub-themes: culture and participation in childbirth, male partners’ employment status, and male partners’ unwillingness to participate in maternal health issues. Conclusions: The involvement of male partners in maternal healthcare services, and further research in promoting this activity, should be proposed to policymakers. Keywords: Views, partners, involvement, maternal health care services, antenatal care, labour and postnatal care.

The discourse on Black boys tends to suggest that Black boys are in complete peril. We begin with evidence that Black boys are excelling in certain contexts (i.e., in certain states, in certain schools, and in certain courses). We then discuss the ways in which the narratives used by parents, teachers, and Black boys themselves may serve to further reinforce views that Black boys are beyond hope. Research on Black parents suggests that they tend to view their sons as vulnerable and have lower expectations for sons than for daughters. Studies of teachers show that they tend to view Black boys as unteachable, as social problems, and as scary. Research on Black boys shows that they are sometimes complicit in supporting these narratives by engaging in negative or ste reotypical behavior. We also include recent research that includes counter-narratives of Black boys. We end with suggestions for future research.

Laboratory studies of alcohol-inexperienced adolescents show that aggression can be primed by alcohol-related stimuli, suggesting that alcohol-related aggression is partly socially learned. Script theory proposes that alcohol-related aggression 'scripts' for social behaviors are culturally-available and learned by individuals. The purpose of the study was to understand the content and origins of alcohol-related aggression scripts learned by adolescents. This qualitative focus group study of 40 adolescents (ages 14-16 years) examined alcohol-related aggression scripts. Participants believed aggression and severe injury to be pervasive when young people drink. Viewed through a biological lens, participants described aggression as an 'instinctive' and 'hard-wired' male trait facilitated by intoxication. As such, alcohol-related aggression was not seen as intended or personally controllable and participants did not see it in moral terms. Females were largely viewed as either bystanders of inter-male aggression or potential victims of male sexual aggression. Participants attributed their views on the frequency and nature of alcohol-related aggression to current affairs and reality television, which they felt portrayed a reality of which they had little experience. The origins of the explicitly biological frameworks that participants used seemed to lie in pre-existing beliefs about the nature of gender differences. Perceptions of the pervasiveness of male alcohol-related aggression, and the consequent failure to view alcohol-related aggression in moral terms, could dispose some young people to alcohol-related aggression. Interventions could target (1) the beliefs that alcohol-related aggression is pervasive and uncontrollable in males, and (2) participants' dysfunctional views of masculinity that underpin those beliefs.

To identify viewpoints among men with depression about depression and its treatment, consider how these might influence help-seeking behaviour, and generate ideas for interventions and future research. Q methodology. Twenty-nine men with depression completed a Q sort by ranking a set of statements about depression and help-seeking according to their relative agreement with each statement. Factor analysis was used to identify viewpoints relating to male understandings of depression and help-seeking, which were interpreted in the context of participant characteristics and additional information from post-sorting interviews. A two-factor solution accounting for 45% of the total variance was considered the best fit for the data. The 2 factors were: (1) Help is available if you can get to the point of asking for it (34% of the variance) and (2) depression should be dealt with in private; help-seeking makes you vulnerable (11% of the variance). Participants who were significantly associated with both factors described a sense of shame, relating to their own or others' views that being depressed and help-seeking are in conflict with socially constructed 'masculine' values, such as strength and self-sufficiency. In the viewpoint represented by Factor 1, however, the benefits of help-seeking outweigh the negatives. In contrast, the viewpoint represented in Factor 2 holds that depression should remain a private struggle and that help-seeking is too risky a move to make. In order to access treatment, men must first recognize depression, then overcome considerable perceived and internalized stigma to ask for help. Improving public knowledge about the nature of depression; positive messages about the act of help-seeking, types of treatment available, and effectiveness of treatments; and work to overcome the challenges posed by long waiting times and other service constraints may increase rates of help-seeking, and represent areas for future research.

The process of establishing a healthy male identity can be difficult for many boys. The limited definitions of masculinity available to boys and men are generally characterized by competition, repression of fear and emotion, and physical and emotional strength. Boys of color and those of lower economic status tend to encounter even fewer healthy…

Research on visual attention triggered by face gender is still relatively sparse. In the present study, three experiments are reported in which male and female participants were required to estimate the midpoint of a line (i.e., the "line bisection task"): at each end of the line a face was presented. Depending on the experimental condition, faces could be of the same gender (i.e., two males or two females) or the opposite gender. Experiments 1 and 2 converged in showing that when a male face was presented at the right and a female face at the left endpoint of the line, a clear rightward bias emerged compared to the other experimental conditions, indicating that male faces captured attention more than female faces. Importantly, male faces used across Experiments 1 and 2 were rated as more threatening than female faces, suggesting that perceived level of threat may have been responsible for the observed bias toward the male face. Experiment 3 corroborated this hypothesis by finding an attentional bias toward the male face with high threat (angry) faces but not with low threat (smiling) faces.

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
Full Text Available Objective. To explore the opinions of Mexican male adolescents regarding teenage pregnancy and analyze its association with sexual behavior. Materials and methods. This is a cross-sectional study using a self-administered questionnaire among a conventional sample of male students (15-19 years old in eight public schools in Morelos and Mexico City. Analyses include multivariate models to identify the association between opinions and sexual behaviors. Results. Overall, 68% agree that a teenage pregnancy is a negative event. In a hypothetical case, if a girlfriend got pregnant in this moment 56% would continue in the school whereas 18% would definitely abandon it. Those who affirm that a teenage pregnancy is something very bad have greater odds of using condoms (OR=1.8; p menor que 0.05. Conclusions. Male adolescents’ views about teenage pregnancy are associated with some sexual behaviors; however their opinions reflect several contradictions. The design of surveys directed exclusively to explore male adolescents’ opinions about reproductive health is urgent.

In the UK, the media are reporting increasing rates of childhood suicide, while highlighting that increasing numbers of pre-adolescent boys (in relation to girls) are diagnosed as mentally ill. In response, academic, professional and political commentators are explaining this as a consequence of gender. One way of doing this has been to apply adult defined understandings of men and masculinities to the attitudes and behaviours of pre-adolescent boys. As a consequence, explanations of these trends point to either 'too much' masculinity, such as an inability to express feelings and seek help, or 'not enough' masculinity that results in isolation and rejection from significant others, such as peer groups. Using a discourse analysis of semi-structured interviews with 28 children aged 9-13 (12 male, 16 females) and 12 school staff at a school in North East England, this article questions the viability of using normative models of masculinity as an explanatory tool for explaining boys' behaviours and suggests that researchers in the field of gender and suicide consider how boys' genders may be constituted differently. We develop this argument in three ways. First, it is argued that studies that use masculinity tend to reduce the formation of gender to the articulation of power across and between men and other men and women. Second, we argue that approaches to understanding boys' behaviours are simplistically grafting masculinity as a conceptual frame onto boy's attitudes and behaviours. In response, we suggest that it is important to re-think how we gender younger boys. The final section focuses specifically on the ways that boys engage in friendships. The significance of this section is that we need to question how notions of communication, integration and isolation, key features of suicide behaviours, are framed through the local production of friendships.

KIAA2022 is an X-linked intellectual disability (XLID) syndrome affecting males more severely than females. Few males with KIAA2022 variants and XLID have been reported. We present a clinical report of two unrelated males, with two nonsense KIAA2022 pathogenic variants, with profound intellectual disabilities, limited language development, strikingly similar autistic behavior, delay in motor milestones, and postnatal growth restriction. Patient 1, 19-years-old, has long ears, deeply set eyes with keratoconus, strabismus, a narrow forehead, anteverted nares, café-au-lait spots, macroglossia, thick vermilion of the upper and lower lips, and prognathism. He has gastroesophageal reflux, constipation with delayed rectosigmoid colonic transit time, difficulty regulating temperature, several musculoskeletal issues, and a history of one grand mal seizure. Patient 2, 10-years-old, has mild dysmorphic features, therapy resistant vomiting with diminished motility of the stomach, mild constipation, cortical visual impairment with intermittent strabismus, axial hypotonia, difficulty regulating temperature, and cutaneous mastocytosis. Genetic testing identified KIAA2022 variant c.652C > T(p.Arg218*) in Patient 1, and a novel nonsense de novo variant c.2707G > T(p.Glu903*) in Patient 2. We also summarized features of all reported males with KIAA2022 variants to date. This report not only adds knowledge of a novel pathogenic variant to the KIAA2022 variant database, but also likely extends the spectrum by describing novel dysmorphic features and medical conditions including macroglossia, café-au-lait spots, keratoconus, severe cutaneous mastocytosis, and motility problems of the GI tract, which may help physicians involved in the care of patients with this syndrome. Lastly, we describe the power of social media in bringing families with rare medical conditions together. © 2018 Wiley Periodicals, Inc.

The need to promote maternal health in Ghana has committed the government to extend maternal healthcare services to the door steps of rural families through the community-based Health Planning and Services. Based on the concerns raised in previous studies that male spouses were indifferent towards maternal healthcare, this study sought the views of men on their involvement in maternal healthcare in their respective communities and at the household levels in the various Community-based Health Planning and Services zones in Awutu-Senya West District in the Central Region of Ghana. A qualitative method was employed. Focus groups and individual interviews were conducted with married men, community health officers, community health volunteers and community leaders. The participants were selected using purposive, quota and snowball sampling techniques. The study used thematic analysis for analysing the data. The study shows varying involvement of men, some were directly involved in feminine gender roles; others used their female relatives and co-wives to perform the women's roles that did not have space for them. They were not necessarily indifferent towards maternal healthcare, rather, they were involved in the spaces provided by the traditional gender division of labour. Amongst other things, the perpetuation and reinforcement of traditional gender norms around pregnancy and childbirth influenced the nature and level of male involvement. Sustenance of male involvement especially, husbands and CHVs is required at the household and community levels for positive maternal outcomes. Ghana Health Service, health professionals and policy makers should take traditional gender role expectations into consideration in the planning and implementation of maternal health promotion programmes.

As very little is known about boys' subjective and emotional experiences when going through puberty, the qualitative research method of grounded theory was used in this study to address the question: "What is the experience of the physical maturational changes in male adolescents?" A Basic Social Psychological Process emerged, Minimizing Embarrassment, with four stages: waiting for the change, noticing the change, dealing with the change, and feeling comfortable with the change. Boys developed expectations from listening to others, by looking at older males, and by wondering and imagining what the changes would eventually be like for them. After developing these expectations, they compared their physical changes to others and to their own expectations. If the boys felt they were different from their peers, they worried about this difference. They used strategies such as avoiding, pretending, and joking to avoid embarrassment or to deal with embarrassing situations. If the boys felt they were "normal," they accepted the fact that they were maturing properly.

Girls outscore boys in reading proficiency levels; the gender gap is startling and concerning. The myth that boys won't read or that it's not "cool" for boys to love reading plays a big part in how these low levels come to be. Low expectations from teachers, and an assumption that boys prefer physical activity, mean that boys often don't find…

Clinical experiences with 36 males, between the ages of 21 and 60 are described. All of them felt an enduring sexual attraction for boys. Sixteen males were treated for sexual identity conflicts. For eight of them this ended in a positive self-labeling as pedophile, the others had severe problems with accepting sexuality as positive and lustful. Twenty males were treated for identity management problems and counseled how to handle their relationships with boys. Several modalities of interpersonal interaction in man-boy relationships are proposed and the ways conflicts can arise within these frames of reference are explored in counseling and psychotherapy.

Young men with superior upper-body strength typically show a greater proclivity for physical aggression than their weaker male counterparts. The traditional interpretation of this phenomenon is that young men calibrate their attitudes and behaviors to their physical formidability. Physical strength is thus viewed as a causal antecedent of aggressive behavior. The present study is the first to examine this phenomenon within a developmental framework. We capitalized on the fact that physical strength is a male secondary sex characteristic. In two longitudinal cohorts of children, we estimated adolescent change in upper-body strength using the slope parameter from a latent growth model. We found that males' antisocial tendencies temporally precede their physical formidability. Boys, but not girls, with greater antisocial tendencies in childhood attained larger increases in physical strength between the ages of 11 and 17. These results support sexual selection theory, indicating an adaptive congruence between male-typical behavioral dispositions and subsequent physical masculinization during puberty. © The Author(s) 2015.

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.

This study investigated geology knowledge acquisition by Boy Scouts through use of the Boy Scout Geology Merit Handbook. In this study, boys engaged in hands-on interactive learning following the requirements set forth in the Geology Merit Badge Handbook. The purposes of this study were to determine the amount of geology content knowledge engendered in adolescent males through the use of the Geology Merit Badge Handbook published by the Boy Scouts of America; to determine if single sex, activity oriented, free-choice learning programs can be effective in promoting knowledge development in young males; and to determine if boys participating in the Scouting program believed their participation helped them succeed in school. Members of a local Boy Scout Troop between the ages of 11 and 18 were invited to participate in a Geology Merit Badge program. Boys who did not already possess the badge were allowed to self-select participation. The boys' content knowledge of geology, rocks, and minerals was pre- and post-tested. Boys were interviewed about their school and Scouting experiences; whether they believed their Scouting experiences and work in Merit Badges contributed to their success in school. Contributing educational theories included single-sex education, informal education with free-choice learning, learning styles, hands-on activities, and the social cognitive theory concept of self-efficacy. Boys who completed this study seemed to possess a greater knowledge of geology than they obtained in school. If boys who complete the Boy Scout Geology Merit Badge receive additional geological training, their field experiences and knowledge acquired through this learning experience will be beneficial, and a basis for continued scaffolding of geologic knowledge.

Distinct gender roles influence gender inequality and build the foundation for gender-based violence. Violence against women is a major public health problem in all societies, and a violation of human rights. Prevalence surveys on gender-based violence have been published from Sri Lanka, but qualitative studies on men's perceptions are lacking. The aim of this study was to explore young educated Sri Lankan men's perceptions of violence against women. Seven focus-group discussions were held. Men at the end of their university studies were purposefully selected. A topic guide was used, covering various scenarios of violence against women. Qualitative content analysis was carried out. Four categories were developed through the analytic process: fixed gender roles - patriarchal values are accepted in society, female mobility control, and slowly changing attitudes; violence not accepted but still exists - sexual harassment exists everywhere, different laws for different people, female tolerance of violence, and men's right to punish; multiple factors cause violence - alcohol, violent behavior is inherited, violence culturally accepted, low education, and lack of communication; and prevention of violence against women - both parents must engage and socialize girls and boys equally, life skills education, premarital counselling, working places value clarification, and more women in politics and boards are suggested. Medical and management students, possible future male leaders of the country, have suggestions of prevention strategies in life skills to reduce gender-based violence and to increase knowledge of health consequences with the aim of changing attitudes.

Among African-Americans, the faith community has a long history of providing support to its members. Because African-American men tend to delay and decline traditional depression treatment, the faith community may be an effective source of support. The aim of this study was to determine how a rural African-American faith community describes and perceives experiences of depression among African-American males. A convenience sample of 24 men and women participated in focus groups and interview. Four themes were identified: defining depression, etiology of depression, denial of depression, and effect of masculine roles on depression experience.

Full Text Available Introduction: Today, it is somewhat possible for general Population to use bicycle as a means of transportation or sport. Physical activity is considered as an important strategy for the prevention and treatment of obesity and other critical metabolic diseases in the different ages of life. Since the Theory of Planned Behavior assesses perceived control beliefs about behaviors, it seems appropriate to study exercise. In the study, the views of male students - as a group which are affective on community norms- about bicycle use were investigated. Method: In this cross-sectional study 250 male students in Yazd University of Medical Sciences responded to a researcher made questionnaire which was designed for assessing their views about bicycle use, based on the Theory of Planned Behavior. The data were analyzed using SPSS v16. Results: The mean age of participants was 23. 01± 3. 83. Findings revealed that the scale means of the theory constructs were as follows: behavioral intention: 8. 54 ±3. 9, Attitude: 2. 97 ± 15. 2, subjective norm: 12. 1± 2. 9 and perceived behavioral control: 17. 5 ±4. 6. Regression analysis indicated that attitude and subjective norm explained 29. 7% of behavioral intention variations (P<0. 001. Conclusion: According to results which indicated that Attitude and subjective norm had more powerful relationship with and predictive power of behavioral intention about using bicycle it is recommended that cultural activities and interventions may be effective to promote using bicycle among students.

Full Text Available The development of modern family patterns of the past decades has been accompanied by substantial changes in social norms, values and gender relations. There is theoretical support for the assumption that the persistence of low fertility levels across Europe is likely to be linked to the incomplete gender revolution, more specifically to the lack of, or only limited changes in the male gender role as opposed to women's role. In order to have a deeper understanding of the development of fertility, we aim to shed more light on the impact of men's role orientation on their fertility intentions in this study. Our analyses include men aged 20-44 years in eight countries: Austria, Estonia, East Germany, West Germany, Italy, Lithuania, the Netherlands and Poland. The data are extracted from the Population Policy Acceptance Study of the early 2000s. Examining within-country differences, we find that men with egalitarian attitudes seem to have higher fertility aspirations than their traditional counterparts in contemporary Europe. This is supported by both the descriptive and the multivariate analyses. The picture is somewhat less conclusive though when we focus on country-rankings by intended family size and by the prevalence of egalitarian versus traditional attitudes.

ABSTRACT Background: Distinct gender roles influence gender inequality and build the foundation for gender-based violence. Violence against women is a major public health problem in all societies, and a violation of human rights. Prevalence surveys on gender-based violence have been published from Sri Lanka, but qualitative studies on men’s perceptions are lacking. Objectives: The aim of this study was to explore young educated Sri Lankan men’s perceptions of violence against women. Methods: Seven focus-group discussions were held. Men at the end of their university studies were purposefully selected. A topic guide was used, covering various scenarios of violence against women. Qualitative content analysis was carried out. Results: Four categories were developed through the analytic process: fixed gender roles – patriarchal values are accepted in society, female mobility control, and slowly changing attitudes; violence not accepted but still exists – sexual harassment exists everywhere, different laws for different people, female tolerance of violence, and men’s right to punish; multiple factors cause violence – alcohol, violent behavior is inherited, violence culturally accepted, low education, and lack of communication; and prevention of violence against women – both parents must engage and socialize girls and boys equally, life skills education, premarital counselling, working places value clarification, and more women in politics and boards are suggested. Conclusions: Medical and management students, possible future male leaders of the country, have suggestions of prevention strategies in life skills to reduce gender-based violence and to increase knowledge of health consequences with the aim of changing attitudes.

The purpose of the study was to explore, within cultural and societal contexts, the factors of spousal HIV transmission as described by the experiences of HIV-positive Cambodian men. Using qualitative research methods, the researchers collected data from in-depth interviews with 15 HIV-positive Cambodian men of seroconcordant couples recruited from an HIV/AIDS clinic in Phnom Penh. Using a model of HIV transmission from husbands to wives, the questions were designed to elicit the men’s perspectives on the topics of promiscuity, masculinity, condom use in marriage, the image of the ideal Cambodian woman, and attitudes toward sex and marriage. Directed content analysis was used to analyze the interview data. The main results were as follows: (a) men involved with sex workers perceived this as a natural behavior and a necessary part of being an approved member in a male peer group, (b) married men never used condoms during sex with their wives prior to their HIV diagnosis, (c) men perceived a good wife as one who is diligent and loyal to her husband, and (4) men’s attitudes toward sex and marriage (e.g., sex perceived as a part of life pleasure) differed from those of their wives. Promoting honest spousal communication about sexuality, maintaining men’s marital fidelity, and increasing women’s comfort in the use of sexual techniques are suggested as strategies for reducing HIV transmission within marriage in Cambodia. Future interventions should focus on reshaping men’s behaviors and changing cultural norms to protect them and their spouses from HIV infection. PMID:28128012

Background In Australia, 15- to 29-year-olds account for 75% of all sexually transmissible infection (STI) diagnoses. STI rates among young men are rising, with most diagnosed in general practice. Young men less frequently attend general practice than young women, and rarely present with sexual health issues, making it difficult for general practitioners (GPs) to offer opportunistic STI education and screening. Little is known of the barriers preventing male university students accessing general practice for sexual health care, or what would facilitate this. Semi-structured interviews were conducted with young men aged 18-24 years attending university between 2012 and 2014. Interviews were recorded, transcribed and analysed using content and thematic analysis. Twenty-eight interviews of 26-50min duration found self-imposed views of masculinity, privacy and embarrassment as key barriers to accessing GPs for sexual health care. This was compounded by poor STI knowledge and not knowing when or where to go for care. Participants, except if they were international students, acknowledged school as an important source of sexual health education. The need for sexual health education at university was identified. While the Internet was a popular source, there were mixed views on the benefits of social media and text messaging for sexual health promotion. Current expectations of young male university students to seek sexual health care or acquire sexual health information from medical care may be misplaced. Universities have an excellent opportunity to provide young men with appropriate sexual health information and could offer novel strategies to help young men look after their sexual health.

This study aimed to identify the types of bullying (physical, verbal, psychological, material, virtual or sexual more prevalent in this population and compare bullying among adolescent males and females. We used a questionnaire prepared by the researcher. Participants were 309 students, 142 males and 167 females, from 6th to 8th grade from two schools, one state and one municipal. These results show 27% of participants were involved in episodes of bullying and that the most prevalent type of bullying was verbal, being appointed for 92% of girls and 84% boys; followed by psychological, indicated by 70% of girls and 53% boys. Physical bullying, had 46% of female and 44% male reports, the material was mentioned by 27% of girls and 16% boys. On sexual bullying type was greatest difference between the sexes, suffered by 38% of girls and 16% boys. Only 13% of girls and 12% boys, mentioned suffer the virtual bullying. Corroborating research area, in this study the highest percentage of victims were female and different from the literature girls reported being verbally abused more for boys than for girls.

Adolescence is a period of transition during which a person is neither considered a child nor an adult. As little is known about adolescent boys' perceptions, norms, role models and gender relations that influence their male identity and behaviour, this qualitative study was conducted. Data were drawn from seven FGDs and twelve mails of adolescent boys (15-19 years old) residing in two townships outside Lusaka and Kitwe in Zambia. Findings show that growing up to a man entails a certain level of ambiguity and contradictory perceptions in terms of supposedly appropriate social and sexual behaviour but indicates a few alternatives. Based on the findings, we recommend that the information gap, misconceptions and anxiety among boys regarding their male identity should be addressed. The respondents suggested that an educational programme that will pay due attention to their needs and answer their questions should be designed and implemented with active involvement of male adolescent peers.
Behavioral change of incarcerated boys is influenced by the alliance with the group workers who support them. This alliance is partly determined by the extent to which both the needs of group workers and boys are being fulfilled. The objective of this research was to explore the views of

Longitudinal studies found that criminal behavior in juveniles often concurs with neighborhood disadvantage and family dysfunction, especially in girls. In this study we assessed the psychosocial background in incarcerated juveniles and analyzed the data for each gender separately. The Multidimensional Clinical Screening Inventory for delinquent juveniles (MCSI) was used to assess school history, psychiatric history, family background, abuse and neglect and motive for crime. The sample consisted of 294 juveniles (46 females and 248 males). Innerfamilial abuse/neglect was reported by 91% (girls) and 79% (boys). 76% (girls) and 88% (boys) reported school-problems. 57% (girls) and 29% (boys) reported to have recieved psychiatric pretreatment. In girls we found significantly higher prevalence rates for parental divorce, incarceration of mother, abuse/neglect and psychiatric pretreatment. Significantly more girls reported a co-occurrence of school-problems and experiences of separation and loss and abuse (65.2% vs. 46.4%, χ²=5.51, df=1, p<.05). Incarcerated juveniles, especially females, are and have been exposed to multiple psychosocial burdens. Therefore it is necessary to implement prevention programs for psychosocially stressed families. Forensic intervention in and after detention has to include a family centered approach.

Since 1971 the Study of Mathematically Precocious Youth (SMPY) at Johns Hopkins University has pioneered in discovery of and provision of educational help for 12-year-old boys and girls who reason better mathematically than 99% of other 12-year-olds. SMPY originated widespread searches for such youths and special academic classes for them outside the regular school system. A regional talent search, verbal as well as mathematical, now covers all 50 states of the USA, and many varied residential summer programmes are offered across the country. These have provided educational facilitation for many thousands, and have encouraged greater curricular flexibility in schools and better articulation of in-school with out-of-school learning experiences. From the first talent search conducted by SMPY in 1972, it became obvious that boys tend to score considerably higher than girls on the College Board Scholastic Aptitude Test-Mathematical (SAT-M), a test intended mainly for college-bound 17- and 18-year-olds. This difference was reported in 1974 but attracted little attention until a controversial report in 1980 stimulated research on sex differences in various aspects of mathematics. Here I describe a study of sex differences over 10 years on 14 College Board high school achievement tests, which are taken (three usually) by bright 17- and 18-year-olds seeking admission to the USA's selective colleges and universities. Among the high scores on the European history test the ratio of males to females was greatest, 6:1. The next most sex-differentiating test was physics, 2.9:1, followed by elementary-level mathematics (mainly algebra and geometry), 2.5:1. Other ratios favouring males were, in 1991, chemistry (2.4:1), American history (2.1:1), biology (1.8:1), precalculus mathematics (1.6:1), Latin (1.6:1), French (1.4:1), modern Hebrew (1.1:1) and German (1.02:1). Tests in which more females were high scorers were literature (1.26:1), English composition (1.05:1) and Spanish (1
Full Text Available PURPOSE: The aim of this study was to evaluate the comprehension and acceptance of HPV vaccination in parents of adolescent boys aged 11 to 15 years. METHODS: A cross-sectional survey was conducted by means of questionnaires sent directly to the homes of all families with young males aged between 11 and 15, residents of three municipalities of the Province of Brescia, Italy. The documentation also contained an informative leaflet summarizing the HPV-related disease characteristics, the burden of disease and the available strategies for prevention and treatment, illustrating the rationale of vaccination and describing the project and its phases. The questionnaire included questions on demographic data, acceptance and motivations for HPV vaccination. The collected data was analyzed using descriptive statistics. At the end of the study, parents who received the questionnaires were also offered the possibility of vaccinating their male sons for free. RESULTS: From a total of 1072 questionnaires sent, 161 where returned from the three selected municipalities (average response rate 15%; 97% of adolescent males involved in the study were Italian and 91% Catholic; 97% of parents declared themselves to be willing to vaccinate their sons: the principal motivation given (92% was prevention of the disease, cancerous or not, related to viral infection. Among the respondents not willing to vaccinate their sons, the motivation was lack of information about the vaccine and the disease. At the end of the study, around 71 boys were vaccinated. DISCUSSION: To our knowledge, this is the first survey in Italy exclusively conducted on parents of adolescent males about the acceptability and feasibility of vaccination against HPV: a very high percentage of respondents was favorable to accept the vaccination for their sons, the main motivation being the fact that parents considered protecting their sons from HPV-related diseases highly important. Of the 161 boys

Congenital absence of the portal vein (CAPV) is a malformation that is generally thought to be limited to females. We encountered an 11-year-old boy with this malformation. In 17 previously reported cases of CAPV, 2 were male. Three male patients, including our case, were Abernethy type Ib malformation. They had no associated liver tumour and two had no additional congenital abnormality. Conversely, 13 of the 15 female patients had congenital abnormalities and 6 had liver mass lesions. (orig.)

In order to evaluate physiological characteristics in young male ballet dancers, 27 boys (aged 9 to 16 years) who participated in a boys' dance course during the Kuopio Dance and Music Festival in June 1988 were studied. In general, the boys had started dancing at the age of 8.6 years and had been training for 4.1 years. They had, on average, three dancing sessions per week and the mean time spent on dancing was four hours per week. In the study, some anthropometric measurements were taken, the maximal oxygen uptake (VO2 max) was measured by a cycle ergometer test and the explosive strength and the mechanical power of lower extremities were evaluated by a jumping test. The results indicate that boys who train in ballet are in general moderately lean, have relatively small body size and a high degree of flexibility. The younger boys especially have only moderate aerobic power, but both explosive strength and mechanical power in leg muscles are good in ballet trained boys. PMID:2630002

The present study was conducted to establish cephalometric norms of Saudi boys based on the Steiners analysis, and to compare the results of the present study with similar studies conducted on other racial or ethnic groups. For this purpose, fifty-five healthy Saudi boys, with a mean age of 12.04 years, were selected from different schools of Riyadh. Female Saudis were not used for this study due to social restrictions with respect to the Kingdom's customs and traditions. Selection was made on the basis of normal occlusion, balanced and pleasing profile with no obvious facial asymmetry. None of the boys have undergone orthodontic treatment prior to this study. Lateral skull cephaiograms were taken and traced using a standardized technique. Each cephalogram was traced twice with a one week interval by the authors. All angular and linear measurements were calculated to the nearest 0.5 degree and 0.5 mm, respectively. Steiners method of cephalometric analysis was used to establish cephalometric norms. The result of the study demonstrated that the Saudi boys differed from other racial and ethnic groups in some skeletal and dental measurements. Generally, the Saudi boys revealed a more protrusive maxillary apical base and double dental protrusion. (author)

In this study, the prevailing view that girls are pervasively more skilled in their friendships than boys was challenged by examining whether girls respond more negatively than boys when a friend violates core friendship expectations. Fourth- and fifth-grade children (n = 267) responded to vignettes depicting transgressions involving a friend's betrayal, unreliability, or failure to provide support or help. Results indicated that girls were more troubled by the transgressions, more strongly endorsed various types of negative relationship interpretations of the friend's actions, and reported more anger and sadness than did boys. Girls also endorsed revenge goals and aggressive strategies just as much as boys. These findings lead to a more complex view of boys' and girls' friendship competencies. © 2011 The Authors.

Previous studies have examined what adolescents find appealing in tobacco and alcohol advertisements and how different themes in advertisements are used to manipulate consumer behaviors. Yet, we know little about the relationship between the themes portrayed in advertisements and youth attitudes towards those themes. This study compared attitudes towards advertisements for different consumer products in a sample of urban and rural adolescent boys in order to examine how key marketing themes impact adolescent attitudes towards those advertisements. Participants were 11- to 16-year-old boys (N = 1220) residing in either urban or rural Ohio Appalachian counties. Each participant viewed five print advertisements (one each for cigarettes, electronic cigarettes (e-cigarettes), smokeless tobacco (SLT), non-alcoholic beverages, and alcohol), presented in a random order, for eight seconds each. All advertisements had appeared in magazines that adolescent males commonly read. Attitudes towards each of the five advertisements were assessed. The advertisements were then coded for the presence of various themes, including social acceptance and masculinity. Analyses were conducted to determine associations between advertisement type and the attitude measure, and between the presence of a theme and the attitude measure. Overall, participants preferred non-tobacco advertisements to tobacco advertisements, rural participants had less positive attitudes and participants who had peers who used tobacco had more positive attitudes. Social acceptance and entertainment themes increased the appeal of SLT advertisements, and sex appeal increased the appeal of e-cigarette advertisements. Conclusions/Importance: Findings suggest that advertisements that promote the social nature of use in SLT advertisements may be of particular concern for their influence on adolescent boys.
What little attention donor-sponsored research on gender and education in Zimbabwe has paid to how schools educate children to assume gender roles has focused on the effect of girls, but it is equally important for development purposes to deconstruct masculinity and the ability of Western stereotypes to foster patriarchy. In Zimbabwe, the school curriculum continues to be gender-differentiated and, when offered a choice, girls and boys choose subjects that fall within the traditional male/female split, which is promoted by teachers, parents, and peers. In addition, males dominate positions of authority in the secondary school system, and teachers of both sexes consider it their duty to steer pupils towards "gender appropriate" behavior. School textbooks further this stereotyping. Interviews in 1995 with 15 secondary school boys at each of six schools sought to uncover attitudes about gender and education. Most boys (77.5%) reported that it is equally important to educate girls and boys, but only 50.6% believed that girls are as intelligent as boys (while differentiating between the type of intelligence possessed by girls with that enjoyed by boys). The boys also gender-typed school subjects on the basis of perceived differentials in abilities and because they are prerequisites for gender-differentiated occupations. Almost 90% of the boys reported that a wife should obey her husband. Thus, patriarchal values are internalized in schools in a way that will impede development.

Healthy boys have a considerable production of reproductive hormones during the first postnatal months, the biological significance of which is poorly understood. We report on cases of male infants with hypogonadism (hypogonadotropic hypogonadism, n = 1; panhypopituitarism, n = 2) who showed lack...... of penile growth and involution of the scrotum. In two boys, diagnoses were obtained in early infancy and hormonal measurements at 3-4 months of age showed serum testosterone levels below detection limits in both low inhibin B (37 and 199 pg/mL, respectively; normal range, 193-563 pg/mL) and low......RH. All cases required hormonal treatment with testosterone, administered as suppositories in daily doses between 1 and 5 mg, which reintroduced male genital development. Our observations suggest that normal phallic and scrotal development in humans is dependent on intact testosterone secretion during...

Unlike the separation-based, stereotyped views of boys' developmental movement into adulthood, this paper will argue that there are more modern and relational models, as well as multiple pathways, for young males to journey through such rites of passage. Indeed, it will be suggested and supported by both qualitative and quantitative data that the more classic models depend on a "boy code" of traumatic separation from mother and the feminine, a process that is not only negative rather than positive in its developmental trajectory, but also likely to create a premature traumatic separation, leaving boys at risk for emotional maladjustment, everyday sadness, increased incidence of depression and the potential for violence toward the self, suicide, as well as violence toward others. More-positive visions and versions of male rites of passage will be posited and described. The definition of emotional "resilience" during this significant period will be re-addressed as one of "healthy vulnerability," sustained through connection to loving adults, rather than a classic belief in stoicism and release from relational ties. Attachment theory will be brought to bear and the desperate yearnings of adolescent males not only for connection to adult mentors, but also for non-romanticized friendships with adolescent females, will be discussed. Finally, the understanding and substitution of these new, more positive, developmental pathways will be linked to the prevention of violence.

The pressure on boys and men to engage in extensive body practices (e.g., closely monitored eating and exercise habits) and achieve ideal male bodies has grown significantly over the past 20 years. Central to the depiction of ideal male bodies and body practices are both the pursuit and achievement of lean and well-defined muscles. The labels "pitches," "purchases," and "performativities" were inductively derived from the literature, and used to describe the multifaceted connections between masculinities, muscularity, and idealized male body practices. "Pitches" distil how popular culture posture norms of masculinity, and manly bodies and behaviors attainable and necessary. "Purchases" refer to men's diverse buy-in to dominant discourses about acceptable male bodies and practices. "Performativities" chronicle how men embody and navigate gender norms as they evaluate their own bodies, behaviors, and eating habits and those of their peers. Based on findings from the current scoping review, future research could benefit from fully linking masculinities with the drive for muscularity to address health and social risks associated with the pursuit of the idealized male body. In highlighting the plurality of masculinities and the complexity of men's diverse identities, health care providers can better reach and support men. Focusing on, and celebrating, a wider range of male bodies could help recenter dominant discourses about how and whose bodies and experiences are idealized. The current scoping review article offers an overview of how masculinities and muscularity have been linked to male body practices, and recommendations to advance this emergent field.

The purpose of this study was to analyze in which physical capabilities boys and girls are closer or distant. An additional objective was to find which of the body fat, physical activity, and somatotype factors have a greater effect on prepubescent children's physical fitness. This was a cross-sectional study involving 312 children (10.8 ± 0.4 years). The physical fitness assessment employed sets of aerobic fitness, strength, flexibility, speed, agility, and balance. The boys presented higher values in all selected tests, except tests of balance and flexibility, in which girls scored better. Gender differences in the physical fitness were greatest in the explosive strength of upper (p ≤ 0.01, η(p)(2) = 0.09) and lower limbs (p ≤ 0.01, η(p)(2) = 0.08), although with a medium-size effect of gender, and smaller in the abdominal (p > 0.05, η(p)(2) = 0.007) and upper limbs (p > 0.05, η(p)(2) = 0.003) muscular endurance, and trunk extensor strength and flexibility (p > 0.05, η(p)(2) = 0.001). The endomorphic (p ≤ 0.01, η(p)(2) = 0.26) in the girls, and the ectomorphic (p ≤ 0.01, η(p)(2) = 0.31) and mesomorphic (p ≤ 0.01, η(p)(2) = 0.26) in the boys, had the high-sized effect on the physical fitness. The physical activity in the girls, and the endomorphic and body fat in the boys, did not have a significant effect. These findings can help in the planning of activities that take into account the success and motivation of both boys and girls and thus increase levels of physical activity and physical fitness at school. However, in prepubescent children, one cannot neglect the influence of genetic determinism, observed from the morphoconstitutional point of view.

Interviews were undertaken with 22 health and social work professionals. Their analysis was completed using "selective transcription", noting understanding of process, issues and themes, and building a picture against which to consider the analysis of subsequent interviews with teenagers and parents. Professionals were also asked to identify areas for feedback from these participants. This work was part of a larger study of (i) the perceptions of adolescent males and their parents of fertility preservation services following a cancer diagnosis, and (ii) national postal surveys of common practices, areas of variance and issues experienced by professionals in UK regional paediatric oncology centres and licensed assisted conception centres. A large number of concerns were identified, which reflected professionals' difficulties in building and maintaining a relevant, adequate knowledge and skills base given the limited numbers of teenagers offered this service. The lack of appropriate training about the legal and consent frameworks, and the processes involved was also highlighted across all professional groups as was the confusion around professional and legal responsibilities for follow up. Thus, there was considerable professional uncertainty in a number of aspects of this sensitive area of service provision. Consideration needs to be given to the needs for national guidance, for training, support and updating, for liaison between the different health and social care sectors that may be involved, and for appropriate information systems. These need to be in place for each stage of the process, from diagnosis through to eventual discharge from the health system.

Mutations involving the cyclin-dependent kinase-like 5 (CDKL5) gene cause an early onset epileptic encephalopathy (EE) with severe neurologic impairment and a skewed 12:1 female-to-male ratio. To date, 18 mutations have been described in boys. We analyzed our cohort of boys with early onset EE to assess the diagnostic yield of our molecular approach. We studied 74 boys who presented early onset severe seizures, including infantile spasms and developmental delay, in the setting of EE, using Sanger sequencing, next-generation sequencing (NGS) and multiplex ligation-dependent probe amplification (MLPA). We identified alterations involving CDKL5 in four boys (5.4%) using NGS in one and MLPA in three. Three of four mutations were indicative of somatic mosaicism. CDKL5 gene mutations accounted for 5.4% of boys with early onset EE. Somatic mosaic mutations might be even more represented than germline mutations, probably because their less deleterious effect enhances viability of the male embryo. The molecular approach used for CDKL5 screening remarkably influences the diagnostic yield in boys. Diagnosis is optimized by Sanger sequencing combined with array-based methods or MLPA; alternatively, NGS targeted resequencing designed to also detect copy number alterations, may be performed.

Animal and human adult studies reveal a contribution of serotonin to behavior regulation. Whether these findings apply to children is unclear. The present study investigated serotonergic functioning in boys with a history of behavior regulation difficulties through a double-blind, acute tryptophan supplementation procedure. Participants were 23 boys (age 10 years) with a history of elevated physical aggression, recruited from a community sample. Eleven were given a chocolate milkshake supplemented with 500 mg tryptophan, and 12 received a chocolate milkshake without tryptophan. Boys engaged in a competitive reaction time game against a fictitious opponent, which assessed response to provocation, impulsivity, perspective taking, and sharing. Impulsivity was further assessed through a Go/No-Go paradigm. A computerized emotion recognition task and a staged instrumental help incident were also administered. Boys, regardless of group, responded similarly to high provocation by the fictitious opponent. However, boys in the tryptophan group adjusted their level of responding optimally as a function of the level of provocation, whereas boys in the control group significantly decreased their level of responding towards the end of the competition. Boys in the tryptophan group tended to show greater perspective taking, tended to better distinguish facial expressions of fear and happiness, and tended to provide greater instrumental help to the experimenter. The present study provides initial evidence for the feasibility of acute tryptophan supplementation in children and some effect of tryptophan supplementation on children's behaviors. Further studies are warranted to explore the potential impact of increased serotonergic functioning on boys' dominant and affiliative behaviors.

Quantitative muscle ultrasound (QUS) in boys with Duchenne muscular dystrophy (DMD) shows increased echointensity as muscle is replaced with fat and fibrosis. Studies of quantitative ultrasound in infants/young boys with DMD over time have not been reported. We used calibrated muscle backscatter (cMB), a reproducible measure of ultrasound echointensity, to quantify muscle pathology in 5 young boys with DMD (ages 0.5-2.8 years) over 17-29 months. We compared the results with repeated assessments of function (n = 4) and with muscle ultrasound images from a cross-section of 6 male controls (0.6-3.1 years). cMB in boys with DMD increased (worsened) over time (P < 0.001), whereas function improved. After age 2 years, cMB in most (4 of 5) boys with DMD was higher than in any control. QUS measures disease progression in young boys with DMD despite functional improvements. QUS could be employed as an outcome measure for serial assessment of young boys with DMD. © 2015 Wiley Periodicals, Inc.

This study aimed to compare moderate-to-vigorous physical activity (MVPA) and vigorous physical activity (VPA) in normal-weight and overweight boys and girls during school recess. Four hundred twenty children, age 6 to 10 years, were randomly selected from 25 schools in England. Three hundred seventy-seven children completed the study. BMI was calculated from height and weight measurements, and heart rate reserve thresholds of 50% and 75% reflected children's engagement in MVPA and VPA, respectively. There was a significant main effect for sex and a significant interaction between BMI category and sex for the percent of recess time spent in MVPA and VPA. Normal-weight girls were the least active group, compared with overweight boys and girls who were equally active. Fifty-one boys and 24 girls of normal weight achieved the 40% threshold; of these, 30 boys and 10 girls exceeded 50% of recess time in MVPA. Eighteen overweight boys and 22 overweight girls exceeded the 40% threshold, whereas 8 boys and 8 girls exceeded the 50% threshold. Overweight boys were significantly less active than their normal-weight male counterparts; this difference did not hold true for girls. Even though nearly double the number of normal-weight children achieved the 40% of MVPA during recess compared with overweight children, physical activity promotion in school playgrounds needs to be targeted not only at overweight but at other health parameters, as 40 overweight children met the 40% MVPA target proposed for recess.

Foetal exposure to antiandrogens alters androgen-sensitive development in male rodents, resulting in less male-typical behaviour. Foetal phthalate exposure is also associated with male reproductive development in humans, but neurodevelopmental outcomes have seldom been examined in relation to phthalate exposure. To assess play behaviour in relation to phthalate metabolite concentration in prenatal urine samples, we recontacted participants in the Study for Future Families whose phthalate metabolites had been measured in mid-pregnancy urine samples. Mothers completed a questionnaire including the Pre-School Activities Inventory, a validated instrument used to assess sexually dimorphic play behaviour. We examined play behaviour scores (masculine, feminine and composite) in relationship to (log(10)) phthalate metabolite concentrations in mother's urine separately for boys (N = 74) and girls (N = 71). Covariates (child's age, mother's age and education and parental attitude towards atypical play choices) were controlled using multivariate regression models. Concentrations of dibutyl phthalate metabolites, mono-n-butyl phthalate (MnBP) and mono-isobutyl phthalate (MiBP) and their sum, were associated with a decreased (less masculine) composite score in boys (regression coefficients -4.53,-3.61 and -4.20, p = 0.01, 0.07 and 0.04 for MnBP, MiBP and their sum respectively). Concentrations of two urinary metabolites of di(2-ethylhexyl) phthalate (DEHP), mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP) and mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and the sum of these DEHP metabolites plus mono(2-ethylhexyl) phthalate were associated with a decreased masculine score (regression coefficients -3.29,-2.94 and -3.18, p = 0.02, 0.04 and 0.04) for MEHHP, MEOHP and the sum respectively. No strong associations were seen between behaviour and urinary concentrations of any other phthalate metabolites in boys, or between girls' scores and any metabolites. These data, although based on

This work is a reflection on the relationship between the use of language and presence. The guidelines given by the Royal Spanish Academy, which advocatesthe use of male generically, are questioned. It seems that being a girl is possible as long as there is not a boy present, at that time her feminine identity is invisible. The rules of the Royal Academy, made from a vision of purely linguistic language, are refuted by several authors who argue that the language has a strong ideological char...

The American Academy of Pediatrics recently released its new Technical Report and Policy Statement on male circumcision, concluding that current evidence indicates that the health benefits of newborn male circumcision outweigh the risks. The technical report is based on the scrutiny of a large number of complex scientific articles. Therefore, while striving for objectivity, the conclusions drawn by the 8 task force members reflect what these individual physicians perceived as trustworthy evidence. Seen from the outside, cultural bias reflecting the normality of nontherapeutic male circumcision in the United States seems obvious, and the report's conclusions are different from those reached by physicians in other parts of the Western world, including Europe, Canada, and Australia. In this commentary, a different view is presented by non-US-based physicians and representatives of general medical associations and societies for pediatrics, pediatric surgery, and pediatric urology in Northern Europe. To these authors, only 1 of the arguments put forward by the American Academy of Pediatrics has some theoretical relevance in relation to infant male circumcision; namely, the possible protection against urinary tract infections in infant boys, which can easily be treated with antibiotics without tissue loss. The other claimed health benefits, including protection against HIV/AIDS, genital herpes, genital warts, and penile cancer, are questionable, weak, and likely to have little public health relevance in a Western context, and they do not represent compelling reasons for surgery before boys are old enough to decide for themselves.

Full Text Available Background The ages of onset of pubertal characteristics are influenced by genetic, geographic, dietary and socioeconomic factors; however, due to lack of country-specific norms, clinicians in Saudi Arabia use Western estimates as standards of reference for local children. Aims The aim of the Riyadh Puberty Study was to provide data on pubertal development to determine the average age of onset of pubertal characteristics among Saudi boys. Methods Cross-sectional study among male school children in Riyadh, Saudi Arabia, in 2006, 542 schoolboys, aged 6 to 16 years old, from diverse socioeconomic levels were selected into the sample using a cluster sample design. Tanner stages were ascertained during physical examination by pediatric endocrine consultants, and also trained pediatric residents and fellows. Results The mean age (standard deviation at Tanner Stages 2, 3, 4, and 5 for pubic hair development of Saudi boys was 11.4 (1.6, 13.3 (1.3, 14.4 (1.0 and 15.1 (0.8 years old, respectively. For gonadal development, the mean age (standard deviation at stages 2, 3, 4, and 5 were 11.4 (1.5, 13.3 (1.2, 14.3 (1.1 and 15.0 (0.9 years old, respectively. Conclusion The ages of onset of pubertal characteristics, based on gonadal development, among Saudi boys are comparable to those reported in Western populations.

To examine outcomes among boys and girls that are associated with prenatal alcohol exposure. Boys and girls with fetal alcohol spectrum disorders (FASD) and randomly-selected controls were compared on a variety of physical and neurobehavioral traits. Sex ratios indicated that heavy maternal binge drinking may have significantly diminished viability to birth and survival of boys postpartum more than girls by age seven. Case control comparisons of a variety of physical and neurobehavioral traits at age seven indicate that both sexes were affected similarly for a majority of variables. However, alcohol-exposed girls had significantly more dysmorphology overall than boys and performed significantly worse on non-verbal IQ tests than males. A three-step sequential regression analysis, controlling for multiple covariates, further indicated that dysmorphology among girls was significantly more associated with five maternal drinking variables and three distal maternal risk factors. However, the overall model, which included five associated neurobehavioral measures at step three, was not significant (p=0.09, two-tailed test). A separate sequential logistic regression analysis of predictors of a FASD diagnosis, however, indicated significantly more negative outcomes overall for girls than boys (Nagelkerke R 2 =0.42 for boys and 0.54 for girls, z=-2.9, p=0.004). Boys and girls had mostly similar outcomes when prenatal alcohol exposure was linked to poor physical and neurocognitive development. Nevertheless, sex ratios implicate lower viability and survival of males by first grade, and girls have more dysmorphology and neurocognitive impairment than boys resulting in a higher probability of a FASD diagnosis.

Frequent calls for more male teachers are being made in English-speaking countries.

Research on youth sexual exploitation in Africa has largely neglected the experiences of exploited boys. To date, much of the research in sub-Saharan Africa continues to consider boys mainly as exploiters but not as exploited. Using the only publicly available population-based surveys from the National Survey of Adolescents, conducted in four sub-Saharan African countries - Burkina Faso, Ghana, Malawi, and Uganda-we assessed factors associated with transactional sexual behaviour among never-married adolescent boys and girls. We also examined whether boys' reported sexual exploitation was linked to similar risky sexual behaviours as has been noted among girls in sub-Saharan Africa. Results from our analyses indicated that even though adolescent girls have a somewhat higher likelihood of reporting sexual abuse and exploitation, the odds of trading sex were significantly elevated for previously traumatized boys (that is those with a history of sexual and physical abuse) but not for their female counterparts. Just like adolescent girls, transactional sexual behaviour was associated with the risk of having concurrent multiple sexual partners for boys. These findings support the reality of boys' sexual exploitation within the African context, and further highlight the importance of including males in general and boys in particular in population-based studies on sexual health, risk, and protective factors in the sub-Saharan African region. Understanding the factors linked to sexual exploitation for both boys and girls will help in developing policies and programs that could improve the overall sexual and reproductive health outcomes among adolescents and youth in sub-Saharan Africa.

Early detection examinations take place from birth to the age of 6 years. The youth screening is a continuation of the screening of the "U-series" and should be carried out between the age of 12-15 and 16-17, respectively. Afterwards adolescent girls have good contact with a gynecologist, but adolescent boys usually do not have a medical contact person who they can trust in. To evaluate the state of knowledge on boys' health, a 15-item comprehensive knowledge survey was conducted among ninth grade students at 7 secondary schools (Gymnasien) in North Rhine-Westphalia. The knowledge survey took place at three specified times (before, immediately after and approximately 3 months after adolescent sexual education classes). Only completed questionnaires were analyzed and evaluated in a gender-specific manner. Overall, 459 students participated from March-September 2017. Before sexual education instruction, about half of all questions were answered correctly by the students. Immediately after class, the proportion increased by a factor of 1.5 to a total of 79.24%. Then 2-3 months after the class, the percentage was 69.67%. Considering gender separately, this resulted in an increase of 15.32% for the female students and 16.99% for the male students. The knowledge survey reveals a need to catch up on facts on the subject of boys' health. Despite evidence of an increase in knowledge of both sexes after sexual education instruction, there is a gender gap. Hence, a preventive check-up especially for boys should be established and offered. Issues such as the prevention of sexually transmitted diseases, options for vaccination against human papillomavirus, etc. should be actively addressed.

Full Text Available In this paper the author summarizes several life history case studies of adolescent boys who were identified at school as “wimps” and who eventually engaged in various forms of sexual violence. Such boys rarely are— if at all—discussed in the childhood, education and feminist literatures on sexual violence. The life stories reveal the interrelationship among inschool bullying, reflexivity, embodied structured action, and the social construction of heteromasculinities in the commission of sexual violence by subordinated boys. The author concludes by considering the implications the research has to the evolving discourses on social scientific conceptualizations of reflexive embodiment and heteromasculinities.

BACKGROUND AND OBJECTIVE Globally, little evidence exists on sexual violence against boys. We sought to produce the first internationally comparable estimates of the magnitude, characteristics, risk factors, and consequences of sexual violence against boys in 3 diverse countries. METHODS We conducted nationally representative, multistage cluster Violence Against Children Surveys in Haiti, Kenya, and Cambodia among males aged 13 to 24 years. Differences between countries for boys experiencing sexual violence (including sexual touching, attempted sex, and forced/coerced sex) before age 18 years were examined by using χ2 and logistic regression analyses. RESULTS In Haiti, Kenya, and Cambodia, respectively, 1459, 1456, and 1255 males completed surveys. The prevalence of experiencing any form of sexual violence ranged from 23.1% (95% confidence Interval [CI]: 20.0–26.2) in Haiti to 14.8% (95% CI: 12.0–17.7) in Kenya, and 5.6% (95% CI: 4.0–7.2) in Cambodia. The largest share of perpetrators in Haiti, Kenya, and Cambodia, respectively, were friends/neighbors (64.7%), romantic partners (37.2%), and relatives (37.0%). Most episodes occurred inside perpetrators’ or victims’ homes in Haiti (60.4%), contrasted with outside the home in Kenya (65.3%) and Cambodia (52.1%). The most common time period for violence in Haiti, Kenya, and Cambodia was the afternoon (55.0%), evening (41.3%), and morning (38.2%), respectively. Adverse health effects associated with violence were common, including increased odds of transactional sex, alcohol abuse, sexually transmitted infections, anxiety/depression, suicidal ideation/ attempts, and violent gender attitudes. CONCLUSIONS Differences were noted between countries in the prevalence, characteristics, and risk factors of sexual violence, yet associations with adverse health effects were pervasive. Prevention strategies tailored to individual locales are needed. PMID:27244799

Sex differences in spatial ability are a seriously debated topic, given the importance of spatial ability for success in the fields of science, technology, engineering, and mathematics (STEM) and girls' underrepresentation in these domains. In the current study we investigated the presence of stereotypic gender beliefs on spatial ability (i.e., "spatial ability is for boys") in 10- and 12-year-old children. We used both an explicit measure (i.e., a self-report questionnaire) and an implicit measure (i.e., a child IAT). Results of the explicit measure showed that both sexes associated spatial ability with boys, with boys holding more male stereotyped attitudes than girls. On the implicit measure, boys associated spatial ability with boys, while girls were gender-neutral. In addition, we examined the effects of gender beliefs on spatial performance, by experimentally activating gender beliefs within a pretest-instruction-posttest design. We compared three types of instruction: boys are better, girls are better, and no sex differences. No effects of these gender belief instructions were found on children's spatial test performance (i.e., mental rotation and paper folding). The finding that children of this age already have stereotypic beliefs about the spatial capacities of their own sex is important, as these beliefs may influence children's choices for spatial leisure activities and educational tracks in the STEM domain.

During the past decades, increased TV viewing and reduced physical activity (PA) levels may have contributed to the increased prevalence of pediatric obesity. This study aimed to analyze the association between TV viewing and central adiposity risk in Portuguese children. The sample comprised 3987 children (1997 girls and 1990 boys) aged 7-9 years. Height, weight, and waist circumference (WC) were measured. Waist-to-height ratio (WHtR) was calculated as the ratio of waist/height with a cut-off of 0.5 used to define risk of abdominal obesity. WHtR does not depend on sex- or age-specific reference criteria. TV viewing and PA were assessed by questionnaire. Logistic regressions were used, with adjustments for age, PA, and parental education. This study revealed a positive significant association between central adiposity risk and sedentary behaviors in Portuguese boys. In addition, the final model showed an important inverse association between PA and the risk of abdominal obesity in both boys and girls (males: β = -0.01 95% CI, 0.99 to 1.00; females: β = -0.01; 95% CI, 0.99-1.00). Findings revealed that associations between TV viewing and obesity risk could be highly influenced by socioeconomic factors. Future research should extend a similar design to children in other geographic contexts, and incorporate other behavioral variables in the statistical models, to confirm or not some of the aforementioned findings. © 2017 Wiley Periodicals, Inc.

Background: ADHD is diagnosed and treated more often in males than in females. Research on gender differences suggests that girls may be consistently underidentified and underdiagnosed because of differences in the expression of the disorder among boys and girls. One aim of the present study was to assess in a clinical sample of medication naïve boys and girls with ADHD, whether there were significant gender x diagnosis interactions in co-existing symptom severity and executive function (EF) ...
Full Text Available Language is a condition for a subject's formation, and identity is a factor in a subject's understanding of self. The Japanese-derived literary forms boys' love and yaoi portray male subjects as valorizing and acting on same-sex erotic desire, yet with little or no sense of possessing a same-sex desiring identity. Following Elizabeth Grosz, Julia Kristeva, and Michel Foucault, a reading is performed of a Western yaoi fan fic to explore how subjects in yaoi and boys' love enter into language, and hence subjectivity.

Background: Phthalates are used as plasticizers in soft polyvinyl chloride (PVC) and in a large number of consumer products. Because of reported health risks, diisononyl phthalate (DiNP) has been introduced as a replacement for di(2-ethylhexyl) phthalate (DEHP) in soft PVC. This raises concerns because animal data suggest that DiNP may have antiandrogenic properties similar to those of DEHP. The anogenital distance (AGD)—the distance from the anus to the genitals—has been used to assess reproductive toxicity. Objective: The objective of this study was to examine the associations between prenatal phthalate exposure and AGD in Swedish infants. Methods: AGD was measured in 196 boys at 21 months of age, and first-trimester urine was analyzed for 10 phthalate metabolites of DEP (diethyl phthalate), DBP (dibutyl phthalate), DEHP, BBzP (benzylbutyl phthalate), as well as DiNP and creatinine. Data on covariates were collected by questionnaires. Results: The most significant associations were found between the shorter of two AGD measures (anoscrotal distance; AGDas) and DiNP metabolites and strongest for oh-MMeOP [mono-(4-methyl-7-hydroxyloctyl) phthalate] and oxo-MMeOP [mono-(2-ethyl-5-oxohexyl) phthalate]. However, the AGDas reduction was small (4%) in relation to more than an interquartile range increase in DiNP exposure. Conclusions: These findings call into question the safety of substituting DiNP for DEHP in soft PVC, particularly because a shorter male AGD has been shown to relate to male genital birth defects in children and impaired reproductive function in adult males and the fact that human levels of DiNP are increasing globally.

We describe current pubertal development in healthy urban Chinese boys. A cross-sectional study of the pubertal development of 18,807 urban Chinese boys aged from 3.50 to 18.49years was conducted between 2003 and 2005. Testicular volume was evaluated with a Prader orchidometer. Pubic hair development was assessed according to the Tanner method. Data on spermarche were collected using the status quo method. Probit analysis was used to calculate the median age and 95% CI at different stages of testicular development, pubic hair development and spermarche. By age 9, 12.99% of the boys had a testicular volume of 4mL or greater. The median age of onset of puberty defined as the age at attainment of testicular volume of 4mL or greater was 10.55 (95% CI 10.27-10.79) years. The median age for onset of pubic hair development (PH(2) ) and spermarche was 12.78 (95%CI 12.67-12.89) years and 14.05 (95%CI 13.80-14.32) years, respectively. Pubertal onset in urban Chinese boys is earlier than currently used clinical norms but their pubic hair development occurs relatively late in comparison with the reported data from numerous other countries. There is also evidence of a secular trend towards an earlier age of spermarche since 1979 in Chinese urban boys. © 2011 The Authors.

In a period of 6 years 144 asymptomatic boys with cryptorchidism, of mean age 7 ± SD 3.5 years, underwent orchiopexy. None of these boys referred to a history of a known urological anomaly, urinary tract infection haematuria, palpable mass in the renal region, bladder extrophy, epispadias, hypospadias or anorectal malformation. On the third day after orchiopexy an intravenous pyelography was done in every boy following testicular protection against irradiation. Ultrasonic investigation was not available at that time. There were minor urological abnormalities in 36 (25%) boys and major ones in 8 (5.5%) boys. A major anomaly is defined as one resulting in significant loss of renal substance (one case of single kidney and three cases of unilateral renal hypoplasia), or requiring surgical correction for conservation of the renal substance (one case of ureterocele, two cases of pelviureteric stenosis and one case of vesicoureteric stenosis with ipsilateral hydronephrosis). The unsuspected major urological abnormalities are usually ipsilateral to the more undescended testis. They may be associated with a hernia and are more frequent in bilateral cryptorchidism. In conclusion we encourage the routine use of IVP, or ultrasonic investigation or dynamic renal scanning (99 mTc -DTPA), if it is possible, in all patients undergoing orchiopexy for the detection of an unsuspected major renal anomaly.

Full Text Available Introduction and Aim. Down syndrome (DS is associated with numerous developmental abnormalities, some of which cause dysfunctions of the posture and the locomotor system. The analysis of selected features of the foot structure in boys with DS versus their peers without developmental disorders is done. Materials and Methods. The podoscopic examination was performed on 30 boys with DS aged 14-15 years. A control group consisted of 30 age- and gender-matched peers without DS. Results. The feet of boys with DS are flatter compared to their healthy peers. The hallux valgus angle is not the most important feature differentiating the shape of the foot in the boys with DS and their healthy peers. In terms of the V toe setting, healthy boys had poorer results. Conclusions. Specialized therapeutic treatment in individuals with DS should involve exercises to increase the muscle strength around the foot joints, enhancing the stabilization in the joints and proprioception. Introducing orthotics and proper footwear is also important. It is also necessary to monitor the state of the foot in order to modify undertaken therapies.

Objective To assess the long-term association between childhood television viewing and adult unemployment, and if this association is mediated by educational achievement. Method Study members were a general-population birth cohort of 1037 participants born in New Zealand in 1972/1973. Hours of weekday television viewing were reported at ages 5–15. Since age 18, unemployment was assessed retrospectively using life-history calendars to age 32. Information on educational qualifications was collected at age 32. Results Childhood and adolescent television viewing predicted adult unemployment. This association was significant for male study members only (β=0.20, ptelevision viewing remained a predictor of unemployment after adjusting for this (p=0.0035). By logistic regression, each additional hour of daily television viewing was associated with an increased likelihood of spending at least 6 months in unemployment between ages 18–32 years (OR=1.36, 95%, CI=1.06, 1.76, p=0.0157). Conclusion Childhood and adolescent television viewing may have long-lasting consequences for adult unemployment for boys. This association is only partially explained by the association between television viewing and educational achievement. PMID:22178044

Ice hockey is an increasingly popular sport that allows intentional collision in the form of body checking for males but not for females. There is a two- to threefold increased risk of all injury, severe injury, and concussion related to body checking at all levels of boys' youth ice hockey. The American Academy of Pediatrics reinforces the importance of stringent enforcement of rules to protect player safety as well as educational interventions to decrease unsafe tactics. To promote ice hockey as a lifelong recreational pursuit for boys, the American Academy of Pediatrics recommends the expansion of nonchecking programs and the restriction of body checking to elite levels of boys' youth ice hockey, starting no earlier than 15 years of age.

This study examines the relationship of three sociocultural factors-media influence, peer teasing, and parent teasing/comments and three potential moderator variables-self-esteem, social comparison, and endorsement of male strength and athleticism-to drive for muscularity in middle school boys. There were 287 seventh and eighth grade boys who completed a questionnaire measuring these variables as well as body mass index (BMI) and pubertal status. Results indicated that media influence and male physical attributes endorsement were particularly important correlates of drive for muscularity. These findings have implications for programs designed to prevent body dissatisfaction among adolescent boys.

Full Text Available Adolescents with conduct and substance problems ("Antisocial Substance Disorder" (ASD repeatedly engage in risky antisocial and drug-using behaviors. We hypothesized that, during processing of risky decisions and resulting rewards and punishments, brain activation would differ between abstinent ASD boys and comparison boys.We compared 20 abstinent adolescent male patients in treatment for ASD with 20 community controls, examining rapid event-related blood-oxygen-level-dependent (BOLD responses during functional magnetic resonance imaging. In 90 decision trials participants chose to make either a cautious response that earned one cent, or a risky response that would either gain 5 cents or lose 10 cents; odds of losing increased as the game progressed. We also examined those times when subjects experienced wins, or separately losses, from their risky choices. We contrasted decision trials against very similar comparison trials requiring no decisions, using whole-brain BOLD-response analyses of group differences, corrected for multiple comparisons. During decision-making ASD boys showed hypoactivation in numerous brain regions robustly activated by controls, including orbitofrontal and dorsolateral prefrontal cortices, anterior cingulate, basal ganglia, insula, amygdala, hippocampus, and cerebellum. While experiencing wins, ASD boys had significantly less activity than controls in anterior cingulate, temporal regions, and cerebellum, with more activity nowhere. During losses ASD boys had significantly more activity than controls in orbitofrontal cortex, dorsolateral prefrontal cortex, brain stem, and cerebellum, with less activity nowhere.Adolescent boys with ASD had extensive neural hypoactivity during risky decision-making, coupled with decreased activity during reward and increased activity during loss. These neural patterns may underlie the dangerous, excessive, sustained risk-taking of such boys. The findings suggest that the dysphoria, reward

Full Text Available Abstract This report represents the first exploratory study of Chinese men who provide commercial sex services to other men ("money boys" in Jilin Province, People's Republic of China, through a convenience sample drawn from Changchun and Jilin City. A total of 86 active money boy participants (Changchun, n = 49; Jilin City, n = 37 were surveyed concerning background and demographics, basic HIV transmission knowledge, and sexual practices. The survey indicated that while Jilin Province money boy behavior matches other studies concerning propensity to high risk behavior and significant bridging potential, the Jilin money boys, unlike previous studies, exhibited a high level of basic HIV/AIDS transmission knowledge. In spite of this level of knowledge, none of the participants reported always using a condom in their sexual activities. They also exhibited a high level of awareness of voluntary counseling and testing available in the province, yet relatively few had availed themselves of these services. These preliminary findings will be used as a baseline and springboard for continuing study in the Jilin Province money boy community. Even now, however, it is becoming clear that the dynamics of male commercial sex work may vary greatly depending upon local influences, and will necessitate that future interventions are highly tailored to area-specific circumstances.

Traditional views of sexual selection assumed that male-male competition and female mate choice work in harmony, selecting upon the same traits in the same direction. However, we now know that this is not always the case and that these two mechanisms often impose conflicting selection on male sexual traits. Cuticular hydrocarbons (CHCs) have been shown to be linked to both social dominance and male attractiveness in several insect species. However, although several studies have estimated the strength and form of sexual selection imposed on male CHCs by female mate choice, none have established whether these chemical traits are also subject to sexual selection via male-male competition. Using a multivariate selection analysis, we estimate and compare sexual selection exerted by male-male competition and female mate choice on male CHC composition in the broad-horned flour beetle Gnatocerus cornutus. We show that male-male competition exerts strong linear selection on both overall CHC abundance and body size in males, while female mate choice exerts a mixture of linear and nonlinear selection, targeting not just the overall amount of CHCs expressed but the relative abundance of specific hydrocarbons as well. We discuss the potential implications of this antagonistic selection with regard to male reproductive success. © 2016 The Authors.

HPV is related to a number of cancer types, causing a considerable burden in both genders in Europe. Female vaccination programs can substantially reduce the incidence of HPV-related diseases in women and, to some extent, men through herd immunity. The objective was to estimate the incremental benefit of vaccinating boys and girls using the quadrivalent HPV vaccine in Europe versus girls-only vaccination. Incremental benefits in terms of reduction in the incidence of HPV 6, 11, 16 and 18-related diseases (including cervical, vaginal, vulvar, anal, penile, and head and neck carcinomas and genital warts) were assessed. The analysis was performed using a model constructed in Microsoft®Excel, based on a previously-published dynamic transmission model of HPV vaccination and published European epidemiological data on incidence of HPV-related diseases. The incremental benefits of vaccinating 12-year old girls and boys versus girls-only vaccination was assessed (70% vaccine coverage were assumed for both). Sensitivity analyses around vaccine coverage and duration of protection were performed. Compared with screening alone, girls-only vaccination led to 84% reduction in HPV 16/18-related carcinomas in females and a 61% reduction in males. Vaccination of girls and boys led to a 90% reduction in HPV 16/18-related carcinomas in females and 86% reduction in males versus screening alone. Relative to a girls-only program, vaccination of girls and boys led to a reduction in female and male HPV-related carcinomas of 40% and 65%, respectively and a reduction in the incidence of HPV 6/11-related genital warts of 58% for females and 71% for males versus girls-only vaccination. In Europe, the vaccination of 12-year old boys and girls against HPV 6, 11, 16 and 18 would be associated with substantial additional clinical benefits in terms of reduced incidence of HPV-related genital warts and carcinomas versus girls-only vaccination. The incremental benefits of adding boys vaccination are

Addressing gender norms is integral to understanding and ultimately preventing violence in both adolescent and adult intimate relationships. Males are affected by gender role expectations which require them to demonstrate attributes of strength, toughness, and dominance. Discrepancy stress is a form of gender role stress that occurs when boys and men fail to live up to the traditional gender norms set by society. Failure to live up to these gender role expectations may precipitate this experience of psychological distress in some males which, in turn, may increase the risk to engage in physically and sexually violent behaviors as a means of demonstrating masculinity. Five-hundred eighty-nine adolescent males from schools in Wayne County, Michigan completed a survey assessing self-perceptions of gender role discrepancy, the experience of discrepancy stress, and history of physical and sexual dating violence. Logistic regression analyses indicated boys who endorsed gender role discrepancy and associated discrepancy stress were generally at greater risk to engage in acts of sexual violence but not necessarily physical violence. Boys who experience stress about being perceived as "sub-masculine" may be more likely to engage in sexual violence as a means of demonstrating their masculinity to self and/or others and thwarting potential "threats" to their masculinity by dating partners. Efforts to prevent sexual violence perpetration among male adolescents should perhaps consider the influence of gender socialization in this population and include efforts to reduce distress about masculine socialization in primary prevention strategies.

Context Multiple studies have reported an overgrowth in head circumference (HC) in the first year of life in autism. However, it is unclear whether this phenomenon is independent of overall body growth and whether it is associated with specific social or cognitive features. Objectives To examine the trajectory of early HC growth in autism compared with control groups; to assess whether HC growth in autism is independent of height and weight growth during infancy; and to examine HC growth from birth to 24 months in relationship to social, verbal, cognitive, and adaptive functioning levels. Design Retrospective study. Setting A specialized university-based clinic. Participants Boys diagnosed as having autistic disorder (n=64), pervasive developmental disorder–not otherwise specified (n=34), global developmental delay (n=13), and other developmental problems (n=18) and typically developing boys (n=55). Main Outcome Measures Age-related changes in HC, height, and weight between birth and age 24 months; measures of social, verbal, and cognitive functioning at age 2 years. Results Compared with typically developing controls, boys with autism were significantly longer by age 4.8 months, had a larger HC by age 9.5 months, and weighed more by age 11.4 months (P=.05 for all). None of the other clinical groups showed a similar overgrowth pattern. Boys with autism who were in the top 10% of overall physical size in infancy exhibited greater severity of social deficits (P=.009) and lower adaptive functioning (P=.03). Conclusions Boys with autism experienced accelerated HC growth in the first year of life. However, this phenomenon reflected a generalized process affecting other morphologic features, including height and weight. The study highlights the importance of studying factors that influence not only neuronal development but also skeletal growth in autism. PMID:21969460
Full Text Available Background: Some boys with sexual precocity are known to have behavioral problems like increased physical and verbal aggression and school and social maladjustments. It is believed to be due to premature androgen exposure. However, it is not clear why only some develop this problem, difference in etiology could be one explanation. Aim: The aim of the study is to assess behavioral aggression in boys with sexual precocity due to different disorders. Materials and Methods: Seven children, ages three to seven years, were enrolled for this study. Two were diagnosed to have congenital adrenal hyperplasia (CAH, three had testotoxicosis, while two had central precocious puberty. Parents of children with precocious puberty underwent the (CASP questionnaire (children′s aggression scale-parent version. Results: Testosterone levels were high in all patients. Parents denied any history of physical or verbal aggression in the two boys with CAH. Their CASP rating was 0. In contrast, the CASP ratings in the two boys with testotoxicosis and the two with precocious puberty for five domains ranged from 3.1 - 24.2, 2.6 - 8.3,1-5.6,0 - 7.1, and 0 - 1, respectively. In the present study, increased aggression was seen among all the patients with testotoxicosis and both with precocious puberty. In contrast, there were no symptoms of either increased verbal or physical aggression in either of the two patients with CAH. Conclusions: The hormonal milieu in the boys with CAH versus those with sexual precocity due to other causes differed in terms of cortisol and androgen precursors. The androgen excess in CAH children was a consequence of cortisol deficiency. It is possible that cortisol sufficiency is required for androgen-mediated behavioral effects.

Purpose Childhood and adolescent sexual abuse has been shown to lead to increased odds of sexual behaviors that lead to sexually transmitted infections and early pregnancy involvement. Research, meta-analyses, and interventions, however, have focused primarily on girls and young women who have experienced abuse, yet some adolescent boys are also sexually abused. We performed a meta-analysis of the existing studies to assess the magnitudes of the link between a history of sexual abuse and each of three risky sexual behaviors among adolescent boys in North America. Methods The three outcomes were a) unprotected sexual intercourse, b) multiple sexual partners, and c) pregnancy involvement. Weighted mean effect sizes were computed from 10 independent samples, from nine studies published between 1990 and 2011. Results Sexually abused boys were significantly more likely than non-abused boys to report all three risky sexual behaviors. Weighted mean odds ratios were 1.91 for unprotected intercourse, 2.91 for multiple sexual partners, and 4.81 for pregnancy involvement. Conclusions Our results indicate that childhood and adolescent sexual abuse can substantially Influence sexual behavior in adolescence among male survivors. To improve sexual health for all adolescents, even young men, we should strengthen sexual abuse prevention initiatives, raise awareness about male sexual abuse survivors’ existence and sexual health issues, improve sexual health promotion for abused young men, and screen all people, regardless of gender, for a history of sexual abuse.

Although female contraceptives are very effective at preventing unintended pregnancy, some women can not use them because of health conditions or side-effects, leaving some couples without effective contraceptive options. In addition, many men wish to take active responsibility for family planning. Thus, there is a great need for male contraceptives to prevent unintended pregnancies, of which 80-90 million occur annually. At present, effective male contraceptive options are condoms and vasectomy, which are not ideal for all men. Therefore, efforts are under way to develop novel male contraceptives. This paper briefly reviews the advantages and disadvantages of condoms and vasectomies and then discusses the research directed toward development of novel methods of male contraception.

A wide experience with boy-lovers has convinced the author that one can often learn more about them from reading some excellent novels than from so-called scientific studies. All too often research is unreliable because (1) it assumes pedosexual activity is a positive indicator of pedophilia; (2) no distinction is drawn between pseudo-pedophiles and real pedophiles; (3) no difference is recognized between boys and girls as partners; and (4) it is highly distorted by bias. Representative samples for research cannot be drawn from members of boy-love organizations. The incidence of violence is very low in pedophile contacts with boys. The influence can be strong in lasting relationships; it can be either wholesome or unwholesome. Within a relationship, sex is usually only a secondary element, although it can be important in sexual instruction and education. The impact of the law, the hostility of parents and the problem of the partners' inequality are discussed.

single nucleotide polymorphisms (SNPs) nearby JMJD1C are associated with pubertal onset in boys and with male reproduction. 671 peri-pubertal boys, 1,027 young men, 315 fertile men, and 252 infertile men were genotyped for two JMJD1C SNPs (rs7910927 and rs10822184). rs7910927 and rs10822184 showed high...... linkage. Boys with the rs7910927 TT genotype entered puberty 3.6 months earlier than their peers (p = 2.5 × 10-2). In young men, the number of T alleles was associated with decreased levels of SHBG, follicle-stimulating hormone (FSH), testosterone, and testosterone x luteinizing hormone, as well...... on the age at pubertal onset in boys as well as levels of reproductive hormones and testis size in men, emphasizing the relationship between JMJD1C and reproductive functions....

Contraception is an accepted route for the control of population explosion in the world. Traditionally hormonal contraceptive methods have focused on women. Male contraception by means of hormonal and non hormonal methods is an attractive alternative. Hormonal methods of contraception using testosterone have shown good results. Non hormonal reversible methods of male contraception like reversible inhibition of sperm under guidanceare very promising. In this article we have reviewed the curren...

It should be recognized that sexuality in the aging male is of such import that a complete sexual history must be performed. By taking a complete sexual history, facts can be obtained that will allow for appropriate focus relating to a holistic evaluation and will enable us to dispel antiquated sexual myths pertaining to the aging male. If initiated by the history taker, questions concerning sexuality may be discussed more comfortably by the patient. Erectile dysfunction, male sexual response cycle, testosterone, sexually transmitted diseases, human immunodeficiency virus, long-term illness, along with religion and culture are explored in this article with the aim of improving one's knowledge base, self reflection, and awareness of the importance of male sexuality. A complete understanding and appreciation of the aging male's medical history, surgical history, social history, and emotional history as well as his sexual, cultural, and religious concepts will allow the health care provider to better analyze information, and to recommend and provide appropriate advice and treatment to the aging male patient.

A careful examination of young men's sexuality by health professionals in pediatrics, primary care, and reproductive health is foundational to adolescent male sexual health and healthy development. Through a review of existing published data, this article provides background and a developmental framework for sexual health services for adolescent boys. The article first defines and provides an overview of adolescent boys' sexual health, and then discusses developmentally focused research on the following topics: (1) early romantic relationships and the evolution of power and influence within these relationships; (2) developmental "readiness" for sex and curiosity; (3) boys' need for closeness and intimacy; (4) adopting codes of masculinity; (5) boys' communicating about sex; and (6) contextual influences from peers, families, and providers. This article concludes by examining the implications of these data for sexual health promotion efforts for adolescent males, including human papillomavirus vaccination.

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

Full Text Available We present the case of a boy with a clinical diagnosis of Goltz syndrome (focal dermal hypoplasia, a rare genodermatosis characterized by widespread dysplasia of mesodermal and ectodermal tissues. A 9-year-old male patient with Goltz syndrome presented with typical skin lesions along with progressive dimness of vision and mental retardation since birth. It is inherited in an X-linked dominant fashion and is normally lethal in male patients, and so very few male patients, like the index case, have been reported.

Although important new strategies have improved outcomes for very preterm infants, males have greater mortality/morbidity than females. We investigated whether the excess of adverse later effects in males operated through poorer neonatal profile or if there was an intrinsic male effect. Male sex was significantly associated with higher birth weight, death or oxygen dependency (72% vs. 61%, boys vs. girls), hospital stay (97 vs. 86 days), pulmonary hemorrhage (15% vs. 10%), postnatal steroids (37% vs. 21%), and major cranial ultrasound abnormality (20% vs. 12%). Differences remained significant after adjusting for birth weight and gestation. At follow-up, disability, cognitive delay, and use of inhalers remained significant after further adjustment. We conclude that in very preterm infants, male sex is an important risk factor for poor neonatal outcome and poor neurological and respiratory outcome at follow-up. The increased risks at follow-up are not explained by neonatal factors and lend support to the concept of male vulnerability following preterm birth. Data came from the United Kingdom Oscillation Study, with 797 infants (428 boys) born at 23-28 wk gestational age. Thirteen maternal factors, 8 infant factors, 11 acute outcomes, and neurological and respiratory outcomes at follow-up were analyzed. Follow-up outcomes were adjusted for birth and neonatal factors sequentially to explore mechanisms for differences by sex.

A recurring finding in autism spectrum disorder research is that head and brain growth is disproportionate to body growth in early childhood. Nordahl et al. (2011) demonstrated that this occurs in approximately 15% of boys with autism. While the literature suggests that brain growth normalizes at older ages, this has never been evaluated in a longitudinal study. The current study evaluated head circumference and total cerebral volume in 129 male children with autism and 49 age-matched, typica...

We report on three boys suffering from achondroplasia concurrent with enchondromatosis-like metaphyseal changes. Two boys who were examined by molecular analysis harbored a mutation of FGFR3, which occurs in most achondroplastic individuals. Given the prevalence of achondroplasia and enchondromatosis, the metaphyseal changes in these patients are less likely to represent the coincidence of both disorders, but rather to result from a rare consequence of the FGFR3 mutation. Impaired FGFs/FGFR3 signaling pathway in achondroplasia inhibits chondrocytic proliferation, which accounts for most characteristics of achondroplasia. On the other hand, it causes conflicting biological consequences that can suppress or stimulate chondrocytic maturation. In a small subset of achondroplastic individuals, the suppression of chondrocytic maturation may outweigh the stimulation, which leads to cartilaginous overgrowth into the metaphysis, eventually causing the metaphyseal dysplasia found in the present patients.

Male baldness is very common. Its effect on individuals is extremely variable, and in some people it will have a significant adverse effect on their quality of life. The objectives of this article are to help general practitioners (GPs) be aware of potential health problems related to male baldness, to have an approach to assessing hair loss and to be aware of treatment options. Male baldness is, most often, a normal occurrence, but it may have significant effects on a man's health. It may also be a pointer to other potential health issues. The GP is in the ideal position to conduct an initial evaluation, consider other health issues and advise on treatment options.
This article discusses CEDPA's Better Life Options Program in India. The program was initiated in 1987 to challenge gender inequities. The program offers over 400,000 girls a chance to develop skills and self-confidence for increasing their options in education, social mobility, work, health, and family and community roles. CEDPA's partner, Prerana, offers an integrated program that provides literacy training, vocational skills, after-school tutoring, health education, and family life education for about 600 girls/year. Vocational training includes nontraditional skills, such as video production and electronics. Prerana established a parallel program in 1994 for boys and young men that aims to change attitudes about girls and women and traditional gender roles. The program offers vocational skills, such as cooking and candle-making. Family life education teaches gender awareness and provides counseling and services for reproductive health. The Prerana program emphasizes men's shared responsibility in parenthood and sexual behavior, shared contribution to family income, health and nutrition, and prevention of violence against women. Since 1994, the program has included 1200 boys in 6 villages in New Delhi. Boys' enrollment is increasing; several young men have volunteered to become depot holders of contraceptive supplies in their villages. For example, one young man who was part of the Prerana program went on to be a depot holder and then a family planning promoter and counselor. He interacts with both young and older men. His contributions were well received by his village.

Full Text Available Background: Due to lack of detailed standards of sexual maturity in individuals with Intellectual, sensory and motor disability in Iran and the importance of timing of onset of puberty in these individuals, a study is necessary. By knowing the onset of puberty, physiologic and behavioral changes can be traced in these people, as well as the potential impact of the puberty on the underlying disease can be considered. The aim of the study was to investigate of sexual maturation among boys of special schools of Tehran. Materials and Methods: Cross-sectional study was performed on children and adolescents male students in special school in Tehran at 2013. A random, multistage sample 0f 895 boy students of special schools was taken from 25 special schools in five districts of Tehran city. In this study, symptoms and stages of puberty were identified. Pubertal stages were assessed by visual inspection and palpation based on the rating scales of Tanner. In addition, demographic data such as age, height, weight were collected. Then the data were analyzed and mean age of onset of puberty was determined. Results: The mean age of onset of puberty in boys (Genitalia stage 2 was 13.12 ± 1.84 years and sexual maturation was completed at 16.57 ± 1.34 years. The average height at the onset of puberty (Genitalia stage 2 was 151.1 ± 9.91 cm and the average weight was 48.47 ± 10.14kg. The mean BMI for puberty onset was 20.89 ± 5.43. Conclusion: In our study, the mean age of puberty onset in boys with disabilities was 13.12 ± 1.84 years. Compared to the data from healthy boys, our findings indicate that the mean age of pubertal onset in boys with disabilities in special school is higher than that of their healthy counterparts.

The gender issue is relevant to classroom learning in more ways than one. Increasingly in the United States, young boys are saying that school is stupid and they do not like to read. This phenomenon cuts across all demographic groups: it affects affluent white boys in the suburbs no less than it affects black boys in low-income neighborhoods. In…

As adolescence is a critical period of development, and as boys are less inclined than girls to approach the school facility for adolescent counselling, segregated consulting hours were introduced for boys to attract those with problems. The frequency of consultations by boys increased by 25 per cent, and 70 per cent of the boys reported a preference for the segregated consulting hours; 75 per cent appreciated the absence of girls from the waiting room; and of the 42 per cent with special preferences regarding the gender of the staff encountered, half reported preferring a man. Most of the boys presented with defined problems, though many revealed other problems, often relating to sexuality, in the course of consultation. The availability of segregated consulting hours for boys with adolescent problems is important, and often the only way to reach young boys who need help.

There is vigorous debate regarding the possibility that ADHD is overdiagnosed in boys. We investigated the impact of the gender stereotype depicting boys as inattentive and impulsive on neuropsychological assessment (observation of psychology students and child's cognitive performance). In experiment 1, after the stereotype was activated, psychology students rated a "boy," a "girl," or a "child" on a behavioral assessment scale. In experiment 2, 103 children (boys and girls) completed neuropsychological tasks under stereotype threat or neutral conditions. The gender stereotype led psychology students to assess a child's behaviors more negatively if they thought the child was a boy. Boys' performance on one cognitive score declined following stereotype threat. Regression path analyses suggested moderation by stigma consciousness. Additionally, there were mediating and suppressing (through stereotype endorsement) effects. Our results suggest that the gender stereotype might contribute to the overdiagnosis of ADHD in boys.

In low-middle income countries and other areas of poverty, menstrual hygiene management (MHM) can be problematic for women and girls. Issues include lack of knowledge about menstruation and MHM, and stigma around menstruation, also access to affordable and absorbent materials; privacy to change; adequate washing, cleaning and drying facilities; as well as appropriate and accessible disposal facilities. In order to effect change and tackle these issues, particularly in patriarchal societies, males may need to become advocates for MHM alongside women. However, little is known about their knowledge and attitudes towards menstruation, which may need addressing before they can assist in acting as advocates for change. The present study was undertaken to explore knowledge and attitudes about menstruation among adolescent boys across India, in order to gauge their potential to support their 'sisters'. The study was undertaken across three states in India, chosen a priori to represent the cultural and socio-economic diversity. Qualitative data using focus group discussions with 85 boys aged 13-17 years, from 8 schools, was gathered. Data were analysed using thematic analysis. The results were organised into three main themes, reflecting the key research questions: boys' knowledge of menstruation, source of knowledge, and attitudes towards menstruation and menstruating girls. Knowledge comprised three aspects; biological function which were generally poorly understood; cultural rites which were recognized by all; and girls' behaviour and demeanour, which were noted to be withdrawn. Some boys learnt about puberty and menstruation as part of the curriculum but had concerns this was not in-depth, or was missed out altogether. Most gathered knowledge from informal sources, from overhearing conversations or observing cultural rituals. Few boys openly displayed a negative attitude, although a minority voiced the idea that menstruation is a 'disease'. Boys were mostly sympathetic

In the food industry, injuries due to food poisoning have been increasing. Especially the mass outbreak of food poisoning by Escherichia coli such as O-157 in 1996 gave warning on the importance of food sanitation management. Public efforts such as the Hazard Analysis and Critical Control Point (HACCP) system have been made to prevent food poisoning. Recently, disinfection made by electrolyzing water with some salt added has attracted attention. Fuji Electric has developed the generator 'SaniBoy' that produces weak alkaline electrolyzed water without wasting water. The environment-friendly 'SaniBoy' will contribute to sanitation in various fields. (author)

To determine whether phosphodiesterase type 5 (PDE5) inhibition can alleviate exercise-induced skeletal muscle ischemia in boys with Duchenne muscular dystrophy (DMD). In 10 boys with DMD and 10 healthy age-matched male controls, we assessed exercise-induced attenuation of reflex sympathetic vasoconstriction, i.e., functional sympatholysis, a protective mechanism that matches oxygen delivery to metabolic demand. Reflex vasoconstriction was induced by simulated orthostatic stress, measured as the decrease in forearm muscle oxygenation with near-infrared spectroscopy, and performed when the forearm muscles were rested or lightly exercised with rhythmic handgrip exercise. Then, the patients underwent an open-label, dose-escalation, crossover trial with single oral doses of tadalafil or sildenafil. The major new findings are 2-fold: first, sympatholysis is impaired in boys with DMD-producing functional muscle ischemia-despite contemporary background therapy with corticosteroids alone or in combination with cardioprotective medication. Second, PDE5 inhibition with standard clinical doses of either tadalafil or sildenafil alleviates this ischemia in a dose-dependent manner. Furthermore, PDE5 inhibition also normalizes the exercise-induced increase in skeletal muscle blood flow (measured by Doppler ultrasound), which is markedly blunted in boys with DMD. These data provide in-human proof of concept for PDE5 inhibition as a putative new therapeutic strategy for DMD. This study provides Class IV evidence that in patients with DMD, PDE5 inhibition restores functional sympatholysis. © 2014 American Academy of Neurology.

Current practice for achieving local control of testicular relapse in males with acute lymphoblastic leukemia (ALL) includes the use of 2,400-rad testicular radiation. Although this therapy is known to cause germ cell depletion, it has been assumed that it does not alter testicular secretion of testosterone. To test this assumption, the authors measured gonadotropin and testosterone levels in seven boys with ALL who had been treated with radiation for clinically apparent testicular relapse. In four of seven boys, testicular relapse was bilateral with overt involvement of one testicle and microscopic involvement of the other. Three of these four boys demonstrated delayed sexual maturation, and in addition to elevated follicle-stimulating hormone (FSH) concentrations, testosterone levels were low and luteinizing hormone levels were elevated compared with controls. These data indicate that boys with overt testicular leukemia who are treated with 2,400-rad testicular radiation are at risk for Leydig cell dysfunction. However, the relative contributions of radiation, prior chemotherapy, and leukemic infiltration to this dysfunction remain to be clarified

Eating habits of 104 male participants (ages 10 to 14 years) in organized ice hockey were compared across age groups and levels of competition. The boys were members of either a highly skilled and intensively active competitive league group (CL) or a less skilled, moderately active house league group (HL). Eating habits were recorded during a school day from a 24 hour recall questionnaire administered by a trained interviewer. The types and amounts of foods eaten were recorded and caloric intake was calculated. The total caloric intakes were not significantly different by age or competitive group. The boys had higher caloric intakes by age (200 kcal day-1) than reported by other studies but the caloric intake by kilogram of body weight was similar. There was a trend towards larger caloric intake by the CL boys (ages 10 and 11 years), however when divided by body weight the differences were not significant suggesting that this trend was due to a greater body weight of the CL boys and not a significantly increased caloric expenditure. The types of foods eaten (fruit, vegetables, dairy, meat, bread or "empty calories") were similar for the two activity groups and across ages 10 to 14 years. The caloric intakes of dairy and meat products of both groups were significantly higher than for the other food groups.

This study described and compared the health perceptions and behaviors of 83 school-age boys and girls. An age-appropriate interview schedule was designed to collect data related to demographic characteristics, health perceptions, safety, life-style practices, nutrition, dental health, and care of minor injuries. Findings indicated that most boys and girls viewed themselves as healthy and managed their own care fairly well in the areas of seat belt use, exercise, and dental health. Nutrition was identified as an area of concern, with 10% of the children skipping breakfast, and over half eating snacks with empty calories. Generally, children were found to be knowledgeable in the management of simple injuries and how to respond in the event of an emergency. Boys and girls were similar in all areas of health perceptions and behaviors except for dental health, with boys reporting more regular visits to the dentist than did girls. Further research is needed to learn more about the process by which school-age children acquire positive health behaviors to assist nurses to design and implement intervention programs that appropriately address the needs of this age group.

Why are boys at risk? To address this question, I use the perspective of regulation theory to offer a model of the deeper psychoneurobiological mechanisms that underlie the vulnerability of the developing male. The central thesis of this work dictates that significant gender differences are seen between male and female social and emotional functions in the earliest stages of development, and that these result from not only differences in sex hormones and social experiences but also in rates of male and female brain maturation, specifically in the early developing right brain. I present interdisciplinary research which indicates that the stress-regulating circuits of the male brain mature more slowly than those of the female in the prenatal, perinatal, and postnatal critical periods, and that this differential structural maturation is reflected in normal gender differences in right-brain attachment functions. Due to this maturational delay, developing males also are more vulnerable over a longer period of time to stressors in the social environment (attachment trauma) and toxins in the physical environment (endocrine disruptors) that negatively impact right-brain development. In terms of differences in gender-related psychopathology, I describe the early developmental neuroendocrinological and neurobiological mechanisms that are involved in the increased vulnerability of males to autism, early onset schizophrenia, attention deficit hyperactivity disorder, and conduct disorders as well as the epigenetic mechanisms that can account for the recent widespread increase of these disorders in U.S. culture. I also offer a clinical formulation of early assessments of boys at risk, discuss the impact of early childcare on male psychopathogenesis, and end with a neurobiological model of optimal adult male socioemotional functions. © 2017 Michigan Association for Infant Mental Health.

To review the specific radiological signs of male breast pathology observed in our center over the past five years, as well as the pertinent medical literature. A retrospective study was carried out of the 47 mammographic studies performed in 41 men. Oblique mediolateral and craniocaudal views were employed. The distribution of different types of male breast pathology among our patients was as follows: gynecomastia was detected in 30 cases (73.1%), pseudogynectomastia in 4 (9.7%), carcinoma in 3(7.3%), abscess in 2 (4.9%), lipoma in 1 (2.5%) and epidermoid cyst in the remaining patient (2.5%). The results obtained agree with those reported in the literature reviewed. The most significant findings were the low incidence of carcinoma and the high rate of gynecomastia. (Author) 26 refs

The present study compared effects of erotic and non-erotic depictions of male-male intimacy on the experience of anger in heterosexual men. Data came from three independent laboratory studies designed to elicit anger in response to erotic or non-erotic depictions of male-male and male-female intimacy. All participants completed a measure of sexual prejudice and anger was assessed before and after viewing the erotic or non-erotic video. Among high-prejudiced men, viewing erotic and non-erotic intimate behavior between two men elicited significant increases in anger relative to viewing comparable behavior between a male-female dyad. In contrast, among low-prejudiced men, viewing erotic, but not non-erotic, intimate behavior between two men elicited significant increases in anger relative to viewing comparable behavior between a male-female dyad. Implications for understanding heterosexual men's anger, and aggression, toward gay men were discussed.

This article aims to explore Congolese male and female high school students' cultural attitudes concerning virginity. The study employed a qualitative approach to collect data from 56 boys and girls aged 16-20 years old. Eight focus group discussions and 40 individual interviews were conducted among participants from two urban and two rural high schools in South Kivu province. Findings indicate that men are disappointed when they marry non-virgin girls. In fact, most male and female participants perceived girls who were virgins as trustworthy individuals. They believe that the girl's virginity loss brings shame to her family. However, some female participants clearly dissociate from societal views or norms about virginity, and remark that virginity itself is not the key to a successful household nor a guarantee for remaining faithful after marriage. Such traditional norms-in the context of high levels of rape-place enormous pressure on young women and cause them to lie about virginity because they fear losing their fiancés. They indicated that they would lie about it regardless of any consequences they may encounter. In fact, some traditional beliefs need to be challenged and modified.

The emergence of higher reported morbidity in females compared with males is a feature of adolescent health in a large proportion of the world's industrialised countries. In this paper, qualitative data from twenty-five single-sex focus groups (90 participants in total) conducted with 10-, 13-, and 15-year olds in two Scottish schools is used to explore whether symptom reporting is influenced by perceived societal gender- and age-related expectations and the social context of symptom experiences. The degree to which these factors can help explain quantitative evidence of increases in gender differences in symptom reporting during adolescence is also examined. Accounts suggested gender-related expectations act as strict 'rules' for boys and less prohibitive 'guidelines' for girls. An unexpected finding was the extent of similarity between these 'rules' and 'guidelines'. Both boys and girls presented themselves as pressured to react to symptoms in stoic, controlled and independent ways, particularly when in the company of their peers, and both perceived that boys and girls could incur negative consequences if seen to have physical (e.g. stomach ache) or, especially, psychological symptoms (e.g. feeling like crying). These qualitative findings do not suggest that girls are simply more willing than boys to report their symptoms as they get older, which is one potential explanation for the quantitative evidence of increasing gender differences in symptom reporting in adolescence. Rather, the findings suggest a need to highlight both the potentially damaging effects of gender stereotypes which make boys reluctant to seek help for physical and, particularly, psychological symptoms, and the misconception that girls are not similarly reluctant to report illness.

We describe relationships between substance use, conduct disorder (CD), depression, and history of self-injury or suicide attempts, in referred, delinquent, substance involved, adolescent males. Sixty youths (mean age 16.3 years) completed standardized assessments for substance use and other psychiatric disorders, aggressiveness, and social class. All boys met modified criteria for CD. Most had high aggression ratings. Twenty percent had depressive diagnoses. By age 13, 78% had begun regular substance use. Marijuana was the first substance for 42%. The boys had substance dependence on a mean of 3.2 different drugs (usually including alcohol and marijuana), with abuse of an average of one additional drug. CD symptoms began 3.6 years (mean) before regular use. CD symptom count correlated with number of dependence diagnoses, and both of those (but not depression) related significantly to suicide attempt and self-injury histories. Improved understanding of substance involvement in youths with CD may generate more rational prevention and treatment.

A Chinese boy presented at 18 months with intractable epilepsy, developmental delay and autistic features. He had multiple seizure types, including absence, myoclonic seizures, limb spasm and tonic seizures. His seizures were finally controlled at 3 years of age with clonazepam and a short course of chloral hydrate incidentally given for his insomnia. Subsequently, he had improvement in his communication skills. A novel hemizygous missense variant (c.1649G>A; p.R550Q) in exon 12 of CDKL5 gene was detected for him, his asymptomatic mother and elder sister. His phenotype is less severe than other male cases. We recommend screening CDKL5 for boys with pharmarco-resistant epilepsy and a trial of benzodiazepines for Infantile Epileptic Encephalopathy (IEE).

Purpose Addressing gender norms is integral to understanding and ultimately preventing violence in both adolescent and adult intimate relationships. Males are affected by gender role expectations which require them to demonstrate attributes of strength, toughness, and dominance. Discrepancy stress is a form of gender role stress that occurs when boys and men fail to live up to the traditional gender norms set by society. Failure to live up to these gender role expectations may precipitate this experience of psychological distress in some males which, in turn, may increase the risk to engage in physically and sexually violent behaviors as a means of demonstrating masculinity. Methods Five-hundred eighty-nine adolescent males from schools in Wayne County, Michigan completed a survey assessing self-perceptions of gender role discrepancy, the experience of discrepancy stress, and history of physical and sexual dating violence. Results Logistic regression analyses indicated boys who endorsed gender role discrepancy and associated discrepancy stress were generally at greater risk to engage in acts of sexual violence but not necessarily physical violence. Conclusions Boys who experience stress about being perceived as “sub-masculine” may be more likely to engage in sexual violence as a means of demonstrating their masculinity to self and/or others and thwarting potential “threats” to their masculinity by dating partners. Efforts to prevent sexual violence perpetration among male adolescents should perhaps consider the influence of gender socialization in this population and include efforts to reduce distress about masculine socialization in primary prevention strategies.

Recent evidence from the U.S. and from other selected countries is examined on parent sex preferences for their children and how strongly these are held. This involves the significance of these preferences, the social and economic conditions that foster different types of preferences, and how different individuals and societies deal with them. The traditional preference for boys appears to remain nearly universal, which runs contrary to the ideal of "every child a wanted child," and also presents an obstacle to desired declines in fertility in developing countries where sons are still perceived as needed for economic and emotional security. This tendency has been turned around in Japan, Singapore, Hong Kong, and the U.S., where small families are now the ideal. 3 basic approaches to the scientific selection of sex-specific sperm for preselection, the timing of sexual intercourse, the separation of male- and female-bearing sperm followed by artificial insemination, and selective abortion after fetal sex determination indicate that an effective and practical method of sex control is still further off than predicted.

Thyrotoxicosis secondary to Graves' disease developed in a 3-year-old black boy with no previous history of thyroid disease. Thyrotoxicosis is a rare disorder of childhood that is characterized by an accelerated metabolism of body tissues which results from the stimulation of thyroid gland activity induced through a variety of autoantibodies. Historically, less than 5% of all incidents of Graves' disease occur in childhood, and recent studies show an incidence as low as 0.000001%. It is three to eight times more prevalent in females than in males and increases in incidence throughout childhood and adolescence. More than two thirds of childhood cases occur between the ages of 10 and 15 years. A review of the medical literature illustrates that less than 2% of hyperthyroid children in recorded cases are younger than 4 years. Records from Children's Hospital of Oklahoma in Oklahoma City support the unusual nature of this case, the hospital having seen only three children younger than 4 years requiring thyroid ablation therapy in 17 years. Physicians should consider Graves' disease in any child with clinical manifestations of hyperthyroidism, regardless of the age.

This study aimed to predict motor coordination from a matrix of biocultural factors for 173 children (89 boys, 84 girls) aged 7-9 years who were assessed with the Körperkoordinationtest für Kinder test battery. Socioeconomic variables included built environment, area of residence, mother's educational level, and mother's physical activity level (using the International Physical Activity Questionnaire [short version]). The behavioral domain was marked by participation in organized sports and habitual physical activity measured by accelerometers ( ActiGraph GT1M). Indicators of biological development included somatic maturation and body mass index. Among males, the best logistic regression model to explain motor coordination (Nagelkerke R 2 = 50.8; χ 2 = 41.166; p girls, the best logistic regression to explain motor coordination (Nagelkerke R 2 = 40.8; χ 2 = 29.933; p physical activity level (OR = 0.183). This sex-specific, ecological approach to motor coordination proficiency may help promote physical activity during prepubertal years through familiar determinants.

A review of studies which investigated drawings of the ideal man and the occupational aspirations of boys (ages 11-18 years) from several countries indicated that becoming a professional athlete was a popular but unrealistic aspiration for many adolescent boys. Boys who were athletes and nonathletes from diverse ethnic groups and nationalities dreamed of becoming professional athletes. In two additional studies in the United States of America, adolescents were asked why they thought boys most often selected professional athlete as a possible future occupation. Adolescents perceived professional athletes as rich, famous, and glorified. Enhancement of status and financial gain were ranked as more important than the desire to play sports.

In males, the pubertal increase in sex hormone production has been associated with proatherogenic changes in lipid and carbohydrate metabolism. Aromatase inhibitors, a novel treatment modality for some growth disorders, may significantly influence these risk factors for cardiovascular disease by suppressing oestrogen biosynthesis and stimulating gonadal androgen production. In the current study, we explored the effects of aromatase inhibition on lipid metabolism, insulin sensitivity, body composition and serum adiponectin in peripubertal boys. Prospective, double-blind, randomised, placebo-controlled clinical study. Thirty-one boys, aged 9.0-14.5 years, with idiopathic short stature were treated with the aromatase inhibitor letrozole (2.5 mg/day) or placebo for 2 years. During the treatment, the concentrations of sex hormones, IGF-I, lipids, lipoproteins and adiponectin were followed-up. The percentage of fat mass (FM) was assessed by skinfold measurements and insulin resistance by homeostasis model assessment (HOMA) index. In pubertal boys, who received letrozole, high-density lipoprotein cholesterol (HDL-C) decreased by 0.47 mmol/l (P<0.01) during the study. Simultaneously, their percentage of FM decreased from 17.0 to 10.5 (P<0.001), in an inverse relationship with serum testosterone. The concentrations of low-density lipoprotein cholesterol, triglycerides and HOMA index remained at pretreatment level in both groups. Serum adiponectin decreased similarly in letrozole- and placebo-treated pubertal boys (2.9 and 3.3 mg/l respectively). In males, aromatase inhibition reduces HDL-C and decreases relative FM after the start of puberty. The treatment does not adversely affect insulin sensitivity in lean subjects.

Attention-deficit/hyperactivity disorder(ADHD)is one of the most common neuro-developmental disorders occurring in childhood,characterized by symptoms of age-inappropriate inattention,hyperactivity/impulsivity,and the prevalence is higher in boys.Although gray matter volume deficits have been frequently reported for ADHD children via structural magnetic resonance imaging,few of them had specifically focused on male patients.The present study aimed to explore the alterations of gray matter volumes in medicated-naive boys with ADHD via a relatively new voxel-based morphometry technique.According to the criteria of DSM-IV-TR,43medicated-naive ADHD boys and 44age-matched healthy boys were recruited.The magnetic resonance image(MRI)scan was performed via a 3T MRI system with three-dimensional(3D)spoiled gradient recalled echo(SPGR)sequence.Voxel-based morphometry with diffeomorphic anatomical registration through exponentiated lie algebra in SPM8 was used to preprocess the3DT1-weighted images.To identify gray matter volume differences between the ADHD and the controls,voxelbased analysis of whole brain gray matter volumes between two groups were done via two sample t-test in SPM8 with age as covariate,threshold at P<0.001.Finally,compared to the controls,significantly reduced gray matter volumes were identified in the right orbitofrontal cortex(peak coordinates[-2,52,-25],t=4.01),and bilateral hippocampus(Left:peak coordinates[14,0,-18],t=3.61;Right:peak coordinates[-14,15,-28],t=3.64)of ADHD boys.Our results demonstrated obvious reduction of whole brain gray matter volumes in right orbitofrontal cortex and bilateral hippocampus in boys with ADHD.This suggests that the abnormalities of prefrontal-hippocampus circuit may be the underlying cause of the cognitive dysfunction and abnormal behavioral inhibition in medicatednaive boys with ADHD.

Full Text Available Objective: To study the prevalence and characteristics of cigarette smoking among secondary school students (16- to 18-year-old boys and girls in Riyadh city, Saudi Arabia. Methods: We applied a standard two-stage, cross-sectional study design. Secondary schools for both boys and girls in Riyadh city were randomly selected using a cluster sampling method. We used the global youth tobacco survey (GYTS tool to achieve our objectives. Results: Among 1272 students (606 boys and 666 girls, the prevalence of those ever smoked cigarettes was 42.8% (55.6% of boys and 31.4% of girls. The prevalence of current smoking was 19.5% (31.2% of boys and 8.9% of girls. Despite the fact that the majority of students think smoking is harmful, most do not wish to stop smoking, and they had not tried to stop in the past year. Cigarette smoking is significantly associated with the male gender, having friends who smoke, and having parents who smoke, but is not significantly associated with the type of school attended. Conclusion: Smoking prevalence among secondary schools students in Saudi Arabia is high and alarming. There is a need to implement an education program about the risks of smoking and to include parents and friends as healthy models to prevent students from beginning to smoke.

We examined whether maternal utilization of preventive care and history of sexually transmitted infections (STIs) predicted quadrivalent human papillomavirus vaccine (HPV4) uptake among adolescent boys 1 year following the recommendation for permissive use of HPV4 for males. We linked maternal information with electronic health records of 254 489 boys aged 9 to 17 years who enrolled in Kaiser Permanente Southern California health plan from October 21, 2009, through December 21, 2010. We used multivariable Poisson regression with robust error variance to examine whether HPV4 initiation was associated with maternal uptake of influenza vaccine, Papanicolaou (Pap) screening, and history of STIs. We identified a modest but statistically significant association between initiation of HPV4 series and maternal receipt of influenza vaccine (rate ratio [RR] = 1.16; 95% confidence interval [CI] = 1.07, 1.26) and Pap screening (RR = 1.13; 95% CI = 1.01, 1.26). Boys whose mothers had a history of genital warts were more likely to initiate HPV4 (RR = 1.47; 95% CI = 0.93, 2.34), although the association did not reach statistical significance (P = .1). Maternal utilization of preventive care and history of genital warts may influence HPV4 uptake among adolescent boys. The important role of maternal health characteristics and health behaviors needs be considered in intervention efforts to increase vaccine uptake among boys.

Many parents recall hearing of human papillomavirus (HPV) vaccine through drug company advertisements. This study sought to examine whether parents accurately recall the source (ie, sponsor) of advertisements promoting HPV vaccine and the impact of drug company advertisements. A U.S. national sample of 544 parents of adolescent boys aged 11-17 participated in an online between-subjects experiment. Parents viewed an advertisement encouraging HPV vaccination for boys with a logo from a randomly assigned source. Parents rated trust, likability and motivation for vaccination while viewing the advertisement and later indicated who they believed sponsored it. Nearly half (43%) of parents who viewed a hypothetical advertisement containing a logo incorrectly identified the advertisement source. More parents correctly identified the source of drug company advertisements than advertisement from other sources (62% vs. 25%, OR 4.93, 95% CI 3.26 to 7.46). The majority of parents who saw a logo-free advertisement believed a drug company created it (60%). Among parents who correctly identified the advertisement source, drug company advertisements decreased motivation to vaccinate their sons, an association mediated by reduced liking of and trust in the advertisements. Parents were more accurate in identifying drug company advertisements, primarily because they tended to assume any advertisement was from a drug company. Public health organisations may need to take special measures to ensure their messages are not perceived as sponsored by drug companies.

The event of elective abortion to terminate unplanned pregnancies brought to the fore and allowed exploration of issues of fatherliness normally latent and, therefore, not observable in adolescence. This is consistent with the psychoanalytic view that fatherly development is an ongoing process begun long before actual parenthood, encompassing an array of conflicts and themes which are conscious to varying degrees in different developmental stages. Issues expressed by the group of adolescent boys studied were compared with those described in the psychoanalytic literature. Most prominent were regressive wishes for nurturance, competition with one's own father, and efforts to meet paternal ego ideals of maturity and responsibility. Parturition envy and strivings for immortality through offspring were not expressed in this group. Themes of fatherliness were not exclusive; they became intertwined with normal tasks of adolescence and individual dynamics as is illustrated with a clinical case.

African American (AA) boys face serious barriers to academic success, many of which are uncommon--or absent--in the lives of AA girls, other children of color, and European American children. In this chapter, we identify nine critical challenges to the successful education of AA boys and review possible solutions. In addition, we evaluate one particular reform, public single-sex schooling, as a possible solution to the challenges facing AA boys. Considering the evidence, we argue that recent efforts to expand the existence of public single-sex schools are rarely grounded in empirical findings. Given the lack of compelling evidence and the high stakes for AA boys, we call for more rigorous evaluations of the outcomes of sex-segregated programs that specifically target AA boys.

Studies of the relationship of weight status with timing of puberty in boys have been mixed. This study examined whether overweight and obesity are associated with differences in the timing of puberty in US boys. We reanalyzed recent community-based pubertal data from the American Academy of Pediatrics' Pediatric Research in Office Settings study in which trained clinicians assessed boys 6 to 16 years for height, weight, Tanner stages, testicular volume (TV), and other pubertal variables. We classified children based on BMI as normal weight, overweight, or obese and compared median age at a given Tanner stage or greater by weight class using probit and ordinal probit models and a Bayesian approach. Half of boys (49.9%, n = 1931) were white, 25.8% (n = 1000) were African American, and 24.3% (n = 941) were Hispanic. For genital development in white and African American boys across a variety of Tanner stages, we found earlier puberty in overweight compared with normal weight boys, and later puberty in obese compared with overweight, but no significant differences for Hispanics. For TV (≥3 mL or ≥4 mL), our findings support earlier puberty for overweight compared with normal weight white boys. In a large, racially diverse, community-based sample of US boys, we found evidence of earlier puberty for overweight compared with normal or obese, and later puberty for obese boys compared with normal and overweight boys. Additional studies are needed to understand the possible relationships among race/ethnicity, gender, BMI, and the timing of pubertal development.

Full Text Available Despite the frequent association of urinary tract infection with vesicoureteral reflux and urinary calculi, since vesicouretal reflux is induced by bladder stones, the coexistence of vesicoureteral reflux and bladder stones is rare. Because of its occurrence in children belonging to poor socioeconomic groups, it is believed to be a deficiency disorder. Most cases of bladder stones occur between the ages of 2 and 5 years. Common clinical presentations of bladder stones include urinary dribbling and enuresis, frequency of micturition, pain during micturition, pelvic pain and hematuria. We report the occurrence of a large bladder stone in a boy, who experienced intermittent lower abdominal pain and urinary incontinence, both during the day and at night. He had been diagnosed with enuresis and treated in pediatric clinics for 1 year. Delayed diagnosis resulted in bladder stone formation. The stone was larger than 2.5 cm and open vesicolithotomy was therefore selected as the best and safest treatment choice. His symptoms disappeared after surgery. Thorough metabolic and environmental evaluations of such cases are required on an individual basis. Bladder stones should be considered as a possible diagnosis in children presenting with urinary incontinence.

Job's syndrome (hyper IgE syndrome) is a very rare primary immunodeficiency disease that has an annual approximate incidence of less than 1/1,000,000. This manuscript aims to provide education regarding diagnosis and management strategies of this syndrome worldwide. A 6-year-old boy was seen at the clinic secondary to persistent pruritus interfering with sleep. At the age of 2 months, the patient developed diffuse eczematous and desquamating skin lesions. He was subsequently diagnosed with atopic dermatitis and managed conservatively. From 2 months to 7 years of age, intermittent exacerbations of dermatitis persisted despite an aggressive treatment regimen. The serum IgE level increased exponentially over a period of 7 years, with a peak value of 57,400 IU/ml. Molecular genetic testing revealed a dominant negative mutation within the SH2 domain of the Signal Transducer and Activator of Transcription (STAT3) gene. The patient was subsequently diagnosed with Job's syndrome. Management included proper skin care, prophylactic antibiotics, immunomodulating agents, and psychotherapy. Job's syndrome can often go unrecognized and masquerade as atopic dermatitis. Therefore, genetic testing for this condition should be obtained in all patients with treatment-refractory AD. Additionally, psychotherapy can be a successful management strategy for the grating psychological impact that can be imposed on children with excessive pruritus.

Takayusu's disease is a rare disease affecting women predominantly during the child- bearing age. It is a primary vasculitis condition of large-vessels that responds well to steroid therapy. Immunosuppressives and vascular reconstruction may be needed as necessary. Reference was made to the case note of this young boy who was being co-managed by cardiology and vascular clinics. The diagnosis of Takayasu's disease was confirmed by the rheumatology unit and appropriate literature search was done. Takayusu's disease responds well to steroid therapy as exemplified by this patient. There was no relapse of the active inflammation after six months of steroid therapy. A high index of suspicion must be exercise in diagnosing Takayasu's disease. It could be difficult to have a clue early in the disease process because of non-specific presentations. Appropriate referral should however be made to Rheumatologist when the diagnosis is suspected. This will go a long way in delaying the morbidity that is associated with this rare disease.

The relationship between cognitive skills and reading has been well-established. However, the role of motivational factors such as self-efficacy in reading progress is less clear. In particular, it is not clear how self-efficacy relates to word level reading versus comprehension, and whether this differs in boys and girls. This study examines the relationship between self-efficacy, word reading and reading comprehension across the range of reading abilities after controlling for reading-related cognitive factors. One hundred and seventy nine children (86 males and 93 females) between 8 and 11 years old completed a self-report measure of reading self-efficacy together with measures of reading comprehension and word reading, working memory, auditory short-term memory, phonological awareness, and vocabulary. Boys and girls showed similar levels of attainment and reading self-efficacy. Reading self-efficacy was associated with word reading, but not with reading comprehension in either boys or girls. It is argued that this may reflect important differences between reading self-efficacy and more general measures of reading motivation and engagement. Reading self-efficacy is an element of reading motivation that is closely associated with a child's perceived attainments in reading and is less susceptible to the gender differences seen in broader measures.

The "zograscope" is a "visual aid" (commonly known as "optical machine" in the 18th century) invented in the mid-18th century, and in general use until the early 20th century. It was intended to view single pictures (thus not stereographic pairs) with both eyes. The optics approximately eliminates the physiological cues (binocular disparity, vergence, accommodation, movement parallax, and image blur) that might indicate the flatness of the picture surface. The spatial structure of pictorial space is due to the remaining pictorial cues. As a consequence, many (or perhaps most) observers are aware of a heightened "plasticity" of the pictorial content for zograscopic as compared with natural viewing. We discuss the optics of the zograscope in some detail. Such an analysis is not available in the literature, whereas common "explanations" of the apparatus are evidently nonsensical. We constructed a zograscope, using modern parts, and present psychophysical data on its performance.
Remote viewing is the supposed faculty which enables a percipient, sited in a closed room, to describe the perceptions of a remote agent visiting an unknown target site. To provide convincing demonstration of such a faculty poses a range of experimental and practical problems, especially if feedback to the percipient is allowed after each trial. The precautions needed are elaborate and troublesome; many potential loopholes have to be plugged and there will be strong temptations to relax standards, requiring exceptional discipline and dedication by the experimenters. Most reports of remote viewing experiments are rather superficial and do not permit assessment of the experimental procedures with confidence; in many cases there is clear evidence of particular loopholes left unclosed. Any serious appraisal of the evidence would have to go beyond the reports. Meanwhile the published evidence is far from compelling, and certainly insufficient to justify overthrow of well-established scientific principles.

To investigate lower urinary tract (LUT) functions in a prospective study in boys treated for posterior urethral distraction (PUD), as posterior urethral stricture, erectile dysfunction and incontinence can occur after various treatments for this rare injury in children. Eleven boys were treated for PUD and resultant stricture between 1980 and 2000. Their age, the cause of trauma, extent of injury, previous treatment, and continence status were evaluated, and a urodynamic study conducted. Controls were 12 age-matched males who underwent similar cystometrography (CMG) and uroflowmetry. The mean (SD) age at injury was 8 (4) years and the cause was traffic accident in nine and crush injury in two boys. Seven boys had an isolated urethral rupture, two also had a bladder neck injury and two also had a perforated bladder. No gross neurological impairment developed after trauma. Voiding cysto-urethrograms after initial therapy showed vesico-ureteric reflux in five boys, but in only one at the time of the urodynamic studies. At the time of urodynamic study, the mean (SD) age of the patients was 15 (6) years; seven were fully continent, one had intermittent leakage, two were incontinent, and one had nocturnal enuresis. CMG-electromyography (EMG) showed a reduced maximum cystometric capacity in nine patients, reduced compliance in 10, stable detrusor in 11, synergic detrusor-sphincter activity in 11, and residual urine in one. The uroflowmetry-EMG study showed prolonged voiding time and flow time, decreased maximum flow urinary rate (Q(max)) and mean flow rate (Q(avg)). The shape of the flow curve showed an uninterrupted low-amplitude pattern. Comparing these patients with age-matched controls, CMG and uroflowmetry studies showed that the maximum cystometric bladder capacity, compliance, Q(max) and Q(avg) were all significantly lower in patients with PUD, while voiding time and flow time were significantly higher. The LUT deteriorates after treating PUD in boys. CMG and

In his analysis of football hooliganism, Anthony King claims to reveal the historical, conceptual scheme young, male supporters draw upon. This 'masculine vision', he states, is similar to that held by the Freikorps. Both groups are said to adhere to modernist notions of masculinity, sexuality and nationhood, reinforced by rituals which maintain boundaries between these 'proper' males and deviant 'others'. Occasionally, football hooligans breach these boundaries in acts of postmodern transgression. King also claims that fans link sex and violence in their imaginations. In this response I examine King's critique of his fellow theorists; challenge his 'Freikorps-Fans' analogy; demonstrate the problem he has in establishing the sex-violence link and question the relevance of his concept of postmodernity.

The purpose of this study was to evaluate the psychometric properties of an audio computer-assisted self-interviewing Web-based software application called the Social Information Processing Application (SIP-AP) that was designed to assess social information processing skills in boys in 3rd through 5th grades. This study included a racially and ethnically diverse sample of 244 boys ages 8 through 12 (M = 9.4) from public elementary schools in 3 states. The SIP-AP includes 8 videotaped vignettes, filmed from the first-person perspective, that depict common misunderstandings among boys. Each vignette shows a negative outcome for the victim and ambiguous intent on the part of the perpetrator. Boys responded to 16 Web-based questions representing the 5 social information processing mechanisms, after viewing each vignette. Parents and teachers completed measures assessing boys' antisocial behavior. Confirmatory factor analyses revealed that a model positing the original 5 cognitive mechanisms fit the data well when the items representing prosocial cognitions were included on their own factor, creating a 6th factor. The internal consistencies for each of the 16 individual cognitions as well as for the 6 cognitive mechanism scales were excellent. Boys with elevated scores on 5 of the 6 cognitive mechanisms exhibited more antisocial behavior than boys whose scores were not elevated. These findings highlight the need for further research on the measurement of prosocial cognitions or cognitive strengths in boys in addition to assessing cognitive deficits. Findings suggest that the SIP-AP is a reliable and valid tool for use in future research of social information processing skills in boys.

The target boys' verbal behavior was coded into two mutually exclusive content categories, rule-break talk and normative talk. Positive social responses from peer boys for each category of talk were also recorded, and were presumed to reinforce the target boys' verbal behavior. A measure of child deviance was available for each target boy. The generalized mat...

Researchers in intellectual disability have had limited theoretical engagement with mainstream theories of masculinity. In this article, the authors consider what mainstream theories of masculinity may offer to applied research on, and hence to therapeutic interventions with, men and boys with intellectual disability. An example from one research project that explored male sexual health illustrates how using masculinity theory provided greater insight into gendered data. Finally, we discuss the following five topics to illustrate how researchers might use theories of masculinity: (a) fathering, (b) male physical expression, (c) sexual expression, (d) men's health, and (e) underweight and obesity. Theories of masculinity offer an additional framework to analyze and conceptualize gendered data; we challenge researchers to engage with this body of work.

We report here on a 6-year-old boy referred to the laboratory for karyotyping and SHOX microdeletion testing. The most significant clinical findings in this boy were small stature, Madelung deformity, facial dysmorphism, mild mental retardation and behavioral problems. R-, G- and RTBG-banding chromosome analysis showed a normal male karyotype. Fine molecular characterization, by FISH, of terminal Xp microdeletion revealed an associated partial duplication. Further refinement of the molecular analysis indicated an inverted duplication of the Xp22.31-Xp22.32 (13.7 Mb) region including the STS, VCX-A and KAL1 genes, associated with a terminal Xp deletion Xp22.33-Xpter (3.6 Mb) encompassing the SHOX and ARSE genes. Such rearrangements have been characterized for other chromosomal pairs, but this is the first reported male patient involving the short arm of the X chromosome. Molecular analysis of the maternal and patient's microsatellite markers showed interchromatid mispairing leading to non-allelic homologous recombination to be the most likely mechanism underlying this rearrangement. This case highlights the importance of clinically driven FISH investigations in order to uncover cryptic micro-rearrangements. Copyright (c) 2007 Wiley-Liss, Inc.

The 46,XX testicular disorder of sex development (DSD), also known as 46,XX male syndrome, is a rare form of DSD and clinical phenotype shows complete sex reversal from female to male. The sex-determining region Y (SRY) gene can be identified in most 46,XX testicular DSD patients; however, approximately 20% of patients with 46,XX testicular DSD are SRY-negative. The SRY-box 9 (SOX9) gene has several important functions during testis development and differentiation in males, and overexpression of SOX9 leads to the male development of 46,XX gonads in the absence of SRY. In addition, SOX9 duplication has been found to be a rare cause of 46,XX testicular DSD in humans. Here, we report a 4.2-year-old SRY-negative 46,XX boy with complete sex reversal caused by SOX9 duplication for the first time in Korea. He showed normal external and internal male genitalia except for small testes. Fluorescence in situ hybridization and polymerase chain reaction (PCR) analyses failed to detect the presence of SRY, and SOX9 intragenic mutation was not identified by direct sequencing analysis. Therefore, we performed real-time PCR analyses with specific primer pairs, and duplication of the SOX9 gene was revealed. Although SRY-negative 46,XX testicular DSD is a rare condition, an effort to make an accurate diagnosis is important for the provision of proper genetic counseling and for guiding patients in their long-term management.

In early fetal development, the testis secretes – independent of pituitary gonadotropins – androgens and anti-Müllerian hormone (AMH) that are essential for male sex differentiation. In the second half of fetal life, the hypothalamic–pituitary axis gains control of testicular hormone secretion. Follicle-stimulating hormone (FSH) controls Sertoli cell proliferation, responsible for testis volume increase and AMH and inhibin B secretion, whereas luteinizing hormone (LH) regulates Leydig cell androgen and INSL3 secretion, involved in the growth and trophism of male external genitalia and in testis descent. This differential regulation of testicular function between early and late fetal periods underlies the distinct clinical presentations of fetal-onset hypogonadism in the newborn male: primary hypogonadism results in ambiguous or female genitalia when early fetal-onset, whereas it becomes clinically undistinguishable from central hypogonadism when established later in fetal life. The assessment of the hypothalamic–pituitary–gonadal axis in male has classically relied on the measurement of gonadotropin and testosterone levels in serum. These hormone levels normally decline 3–6 months after birth, thus constraining the clinical evaluation window for diagnosing male hypogonadism. The advent of new markers of gonadal function has spread this clinical window beyond the first 6 months of life. In this review, we discuss the advantages and limitations of old and new markers used for the functional assessment of the hypothalamic–pituitary–testicular axis in boys suspected of fetal-onset hypogonadism.

This paradox mirrors the empirical puzzle that forms the starting point for this article: while teachers saw relational aggression as a ‘girl problem’, we found a vast undercurrent of relational aggression among boys. Drawing on ethnographic fieldwork and interviews with staff and students in Norwegian schools, we ask how boys’ relational aggression ca...

Markedly effeminate behavior in a young boy is a source of concern and confusion for parents, teachers, and the child. It also represents a therapeutic dilemma for the child psychiatrist. The case of a five-year-old boy with gender identity disorder of childhood is presented and the literature on hypotheses of etiology, treatment, and long-term follow-up is reviewed. The ethical and philosophical questions posed by such a case are discussed.

MECP2 mutations mainly occur in females with Rett syndrome. Mutations have been described in 11 boys with progressive encephalopathy: seven of nine with affected sisters and two de novo. The authors report four de novo occurrences: three pathogenic and one potentially pathogenic. Common features include failure to thrive, respiratory insufficiency, microcephaly, and abnormal motor control. MECP2 mutations should be assessed in boys with progressive encephalopathy and one or more of respiratory insufficiency, abnormal movements or tone, and intractable seizures.

To investigate whether weight category (underweight, average weight, overweight, and obese) at age 7.5 predicts bullying involvement at 8.5 years. Models were tested separately for boys and girls to investigate gender differences in association patterns. Prospective cohort study in southwest England. Height and weight were measured in children at age 7.5 (n = 8210). BMI (kg/m2) was used to define underweight, average weight, overweight, and obese children, according to British age and gender specific growth reference data. Overt (n = 7083) and relational (n = 6932) bullying behaviour was assessed in children at age 8.5. After adjustment for parental social class, compared to average weight boys, obese boys were 1.66 (95% CI 1.04 to 2.66) times more likely to be overt bullies and 1.54 (1.12 to 2.13) times more likely to be overt victims. Obese girls were 1.53 (1.09 to 2.15) times more likely to be overt victims compared to average weight girls. Obesity is predictive of bullying involvement for both boys and girls. Preadolescent obese boys and girls are more likely to be victims of bullying because they deviate from appearance ideals. Other obese boys are likely to be bullies, presumably because of their physical dominance in the peer group.

To analyze the features of boys with congenital gonadotropin deficiency (CGD), and to determine the value of plasma inhibin B and anti-Müllerian hormone (AMH) for predicting testicular function and the effect of testosterone treatment. We followed 19 boys for CGD, including five with Kallmann syndrome. The boys were seen before 14 years of age for micropenis (9 boys) or later for delayed puberty (10 boys). No testis was palpable in the scrotum in 13 patients, bilaterally in seven of them. Luteinizing hormone (LH) peak after a gonadotropin releasing hormone (GnRH) test was between 0.5 and 5.6 U/l. Plasma inhibin B was low in the four patients evaluated at less than 1 year old. AMH was low in one of them and normal in four others. Of the older patients, three lad low plasma inhibin B and four had normal concentrations; plasma AMH was low in three of them and increased in four. Testosterone treatment restored penis length to normal in all patients. Low plasma inhibin B and AMH concentrations may indicate testicular damage in boys with CGD.

Universal hepatitis B vaccination was recommended for U.S. newborns in 1991; however, safety findings are mixed. The association between hepatitis B vaccination of male neonates and parental report of autism diagnosis was determined. This cross-sectional study used weighted probability samples obtained from National Health Interview Survey 1997-2002 data sets. Vaccination status was determined from the vaccination record. Logistic regression was used to estimate the odds for autism diagnosis associated with neonatal hepatitis B vaccination among boys age 3-17 years, born before 1999, adjusted for race, maternal education, and two-parent household. Boys vaccinated as neonates had threefold greater odds for autism diagnosis compared to boys never vaccinated or vaccinated after the first month of life. Non-Hispanic white boys were 64% less likely to have autism diagnosis relative to nonwhite boys. Findings suggest that U.S. male neonates vaccinated with the hepatitis B vaccine prior to 1999 (from vaccination record) had a threefold higher risk for parental report of autism diagnosis compared to boys not vaccinated as neonates during that same time period. Nonwhite boys bore a greater risk.

Spatial abilities are pertinent to mathematical competence, but evidence of the space-math link has largely been confined to older samples and intrinsic spatial abilities (e.g., mental transformation). The roles of gender and affective factors are also unclear. This study examined the correlations between counting ability, mental transformation, and targeting accuracy in 182 Hong Kong preschoolers, and whether these relationships were weaker at higher spatial anxiety levels. Both spatial abilities related with counting similarly for boys and girls. Targeting accuracy also mediated the male advantage in counting. Interestingly, spatial anxiety moderated the space-math links, but differently for boys and girls. For boys, spatial abilities were irrelevant to counting at high anxiety levels; for girls, the role of anxiety on the space-math link is less clear. Results extend the evidence base of the space-math link to include an extrinsic spatial ability (targeting accuracy) and have implications for intervention programmes. Statement of contribution What is already known on this subject? Much evidence of a space-math link in adolescent and adult samples and for intrinsic spatial abilities. What does this study add? Extended the space-math link to include both intrinsic and extrinsic spatial abilities in a preschool sample. Showed how spatial anxiety moderated the space-math link differently for boys and girls. © 2016 The British Psychological Society.

The male to female ratio is raised in autism spectrum disorders (ASD). Previous studies have suggested that girls with ASD have more problems with communication than boys, but boys show more repetitive behaviours than girls. In this study, 20 girls, 1.8-3.9 years of age were matched for chronological and developmental age with 20 boys with suspected ASD. All the children were recruited after population screening and referral by Child Health Care Services to a specialised neuropsychiatry clinic, where they underwent comprehensive neuropsychiatric assessments. Comparisons were made with regard to diagnosis, developmental profiles and global disability. No significant gender differences were found. There were strong correlations between results obtained in different developmental areas. The results suggest that either (1) previous studies finding clear gender differences may have overrated discrepancies between girls and boys in ASD, or that (2) there may be girls, who will not be identified in the early years with our current screening instruments. More research with a much larger population representative study samples is required. Copyright © 2012 Elsevier Ltd. All rights reserved.

Young male soccer players have been identified as a target group for injury prevention, but studies addressing trends and determinants of injuries within this group are scarce. The goal of this study was to analyze age-specific trends in hospital-treated upper extremity fractures (UEF) among boys playing soccer in the Netherlands and to explore associated soccer-related factors. Data were obtained from a national database for the period 1998-2009. Rates were expressed as the annual number of UEF per 1000 soccer players. Poisson's regression was used to explore the association of UEF with the number of artificial turf fields and the number of injuries by physical contact. UEF rates increased significantly by 19.4% in boys 5-10 years, 73.2% in boys 11-14 years, and 38.8% in boys 15-18 years old. The number of injuries by physical contact showed a significant univariate association with UEF in boys 15-18 years old. The number of artificial turf fields showed a significant univariate association with UEF in all age groups, and remained significant for boys aged 15-18 years in a multivariate model. This study showed an increase of UEF rates in boys playing soccer, and an independent association between artificial turf fields and UEF in the oldest boys. © 2014 John Wiley & Sons A/S.

To examine the association between different levels of childhood attention deficit hyperactivity disorder (ADHD) symptoms and sex differences in psychosocial outcomes during adolescence. Swedish children (n = 4635) were screened for neuropsychiatric symptoms at age 9 or 12. ADHD symptoms were divided into three levels: screen-negative, screen-intermediate, and screen-positive. At follow-up (age 15), parents and teenagers filled out questionnaires regarding (i) hyperactivity/inattention, (ii) peer problems, (iii) school problems, (iv) internalizing problems, (v) antisocial behaviour, (vi) alcohol misuse, and (vii) drug misuse. All outcomes were controlled for symptoms of diagnostic categories other than ADHD. Increasing levels of ADHD symptoms in childhood were associated with higher proportions of adolescents who displayed negative psychosocial outcomes. More girls than boys reported internalizing problems (all levels) and risky drug use (screen-intermediate and screen-positive only). More boys reported antisocial behaviour at the screen-negative and screen-intermediate levels, but at the screen-positive level, similar proportions of girls and boys displayed antisocial behaviour. The findings support the view that ADHD symptoms, as well as their negative outcomes, are dimensionally distributed in the population and that adolescent girls and boys display different risk profiles. The findings confirm that ADHD symptoms are associated with higher risk of drug misuse in girls. © 2016 The Authors. Acta Psychiatrica Scandinavica Published by John Wiley & Sons Ltd.
The gender gap in achievement in science continues to plague science educators (AAAS, 2001). Strategies to close this gap have defined the problem in terms of girls' lack of interest or their inability to survive in science classrooms. Recent feminist scholarship has re-centered this problem of gender inequity not on girls, but on the nature of science and how it is taught in schools (Birke, 1986; Parker, 1997). Lesley Parker (1997) argues that it is schools that need to change and recommends a gender-inclusive science curriculum for schools. My dissertation argues for a new framework and research agenda for understanding the relationship between gender and science in schools. My study examines the gender dynamics of how unequal gender relations are negotiated, resisted and sustained in the context of a second grade science classroom. In examining the gender dynamics between the boys and the girls in a science classroom, I found that the boys positioned the girls as their assistants, as incompetent in science, as weak in contrast to the boys, and in need of the boys' help and protection. These discourses functioned to create and sustain unequal gender relations in the classroom. The girls responded in paradoxical ways to the boys' positioning of them. They resisted the boys by: (a) ignoring them; (b) using a domestic discourse to negotiate/gain more power; (c) appropriating teacher authority; or (d) using sexuality to embarrass and silence the boys. The girls also deferred to the boys as experts in science. In these ways, the girls themselves contributed to maintaining unequal gender relations in the classroom. I found that the classroom context is a site of struggle for both boys and girls as they seek to secure a place in the social hierarchy of the classroom. For the boys, masculinity is strong and powerful yet fragile and vulnerable. The girls struggle in holding multiple images of femininity.

Klinefelter syndrome (47, XXY) is associated with several physical, cognitive, and behavioral consequences. In terms of social development, there is an increased risk of autism symptomatology. However, it remains unclear how social deficits are related to abnormal brain development and to what degree underlying mechanisms of social dysfunction in 47, XXY are similar to, or different from, those in idiopathic autism (ASD). This study was aimed at investigating the neural architecture of brain structures related to social information processing in boys with 47, XXY, also in comparison with boys with idiopathic ASD. MRI scans of 16 boys with 47, XXY, 16 with ASD, and 16 nonclinical, male controls were analyzed using voxel-based morphometry (VBM). A region of interest mask containing the superior temporal cortex, amygdala, orbitofrontal cortex (OFC), insular cortex, and medial frontal cortex was used. The Social Responsiveness Scale (SRS) was used to assess degree of autism spectrum symptoms. The 47, XXY group could not be distinguished from the ASD group on mean SRS scores, and their scores were significantly higher than in controls. VBM showed that boys with 47, XXY have significant gray matter volume reductions in the left and right insula, and the left OFC, compared with controls and boys with ASD. Additionally, boys with 47, XXY had significantly less gray matter in the right superior temporal gyrus than controls. These results imply social challenges associated with 47, XXY may be rooted in neural anatomy, and autism symptoms in boys with 47, XXY and boys with ASD might have, at least partially, different underlying etiologies.

Close parent-adolescent relationships and specific parenting practices (e.g., communication about sex, monitoring) are associated with reduced sexual risk behavior among heterosexual youth. Despite gay/bisexual male youth being at increased risk of HIV, little is known about parental influences on their sexual behavior. As such, the goal of the current study was to examine parent-adolescent relationships and parenting practices related to teen sex and dating from the perspective of gay/bisexual adolescent boys. Online focus groups were conducted with 52 gay/bisexual male youth ages 14-17 years. Most gay/bisexual adolescent boys felt that their sexual orientation had an influence on their relationships with their parents and discussions about sex/dating. Although some felt that their relationships improved after coming out, a larger percentage reported that it put strain on their relationships. Discussions about sex/dating generally decreased after coming out, but some youth described positive conversations with their parents. Many reported that their parents struggled with whether or not to adapt parenting practices (e.g., rules about dating) after they came out. Youth consistently noted that parent-adolescent relationships and parenting practices depended on the adolescent's level of outness. Findings have important implications for refining HIV prevention programs for gay/bisexual adolescent boys, especially interventions that include parents.

Some boys with autism spectrum disorder (ASD) and boys with fragile X syndrome and a codiagnosis of ASD (FXS+ASD) have impairments in expressive grammatical abilities. The current study compared grammatical performance in these 2 groups of school-age boys. Thirty-seven boys similar on mean length of utterance participated in the current study (FXS: n = 19, ASD: n = 18). Participants completed an ASD assessment, nonverbal IQ testing, and conversation language samples. Convergent validity of a sentence imitation task with a norm-referenced assessment of grammar was examined in addition to divergent validity of the measures with nonverbal IQ and vocabulary comprehension and production. The boys with ASD outperformed the boys with FXS+ASD on the norm-referenced assessment of "be," and effect sizes indicate that the boys with ASD had better performance on past tense probes on the sentence imitation task and "do" on the norm-referenced assessment. The two measures of grammar had good convergent validity except for copula and auxiliary "be" and "do." Grammatical performance was not correlated with nonverbal IQ, and trends indicate a relationship between vocabulary and grammar. Despite being similar on mean length of utterance, there were group differences on grammatical performance. The sentence imitation task had good convergent validity with a norm-referenced assessment of grammar for the third-person singular and past tense probes and therefore could be an inexpensive and valid tool to use clinically for these populations. Future research should continue to refine this task, particularly for the probes with high rates of unscorable responses (i.e., "be" and "do").

The current study examined the best friendships of aggressive and nonaggressive boys (N = 96 boys, 48 dyads, mean age = 10.6 years). Friends completed self-report measures of friendship quality, and their interactions were observed in situations that required conflict management and provided opportunities for rule-breaking behavior. Although there were no differences in boys' self-reports of friendship quality, observers rated nonaggressive boys and their friends as showing greater positive engagement, on-task behavior, and reciprocity in their interactions compared with aggressive boys and their friends. Aggressive boys and their friends provided more enticement for rule violations and engaged in more rule-breaking behavior than did nonaggressive boys and their friends. Also, the intensity of negative affect in observed conflicts between aggressive boys and their friends was greater than that between nonaggressive boys and their friends. The findings suggest that friendships may provide different developmental contexts for aggressive and nonaggressive boys. Copyright 2003 Elsevier, Inc.

Full Text Available With CT (computed tomography chest gaining more importance as a diagnostic tool, chest X-ray especially the lateral view is taken less commonly nowadays. Besides CT chest is also proven to be superior to chest X-ray in patients with major blunt trauma. We are presenting a 68-year old male who was partially treated from outside for a left sided pneumonia. He came to our hospital because of persisting chest pain. Chest X-ray, frontal view (postero-anterior was almost normal except for a mild opacity in the left lower zone. CT scan of the chest revealed a fluid collection posteriorly enclosed within enhancing pleura. Chest X-ray, left lateral view showed a corresponding posterior pleural based opacity. We are presenting this case to highlight the importance of the lateral view of the chest X-ray. In selected cases there is still a role for the lateral view. With the three dimensional visualization provided by the CT, the lateral view of the chest may be easier to understand. Consequent to the initial diagnosis by CT further follow up can be done with the chest X-ray. In a limited way this mitigates unnecessary expenditure and more importantly prevents the patient from exposure to harmful radiation in the form of repeated CT.
Full Text Available Sex differences in human social behaviors and abilities have long been a question of public and scientific interest. Females are usually assumed to be more socially oriented and skillful than males. However, despite an extensive literature, the very existence of sex differences remains a matter of discussion while some studies found no sex differences whereas others reported differences that were either congruent or not with gender stereotypes. Moreover, the magnitude, consistency and stability across time of the differences remain an open question, especially during childhood. As play provides an excellent window into children's social development, we investigated whether and how sex differences change in social play across early childhood. Following a cross-sectional design, 164 children aged from 2 to 6 years old, divided into four age groups, were observed during outdoor free play at nursery school. We showed that sex differences are not stable over time evidencing a developmental gap between girls and boys. Social and structured forms of play emerge systematically earlier in girls than in boys leading to subsequent sex differences in favor of girls at some ages, successively in associative play at 3-4 years, cooperative play at 4-5 years, and social interactions with peers at 5-6 years. Preschool boys also display more solitary play than preschool girls, especially when young. Nevertheless, while boys catch up and girls move on towards more complex play, sex differences in social play patterns are reversed in favor of boys at the following ages, such as in associative play at 4-5 years and cooperative play at 5-6 years. This developmental perspective contributes to resolve apparent discrepancies between single-snapshot studies. A better understanding of the dynamics of sex differences in typical social development should also provide insights into atypical social developments which exhibit sex differences in prevalence, such as autism.

Full Text Available X-linked ichthyosis (XLI is a rare dermatological condition arising from deficiency for the enzyme steroid sulfatase (STS. Preliminary evidence in boys with XLI, and animal model studies, suggests that individuals lacking STS are at increased risk of developmental disorders and associated traits. However, the behavioural profile of children with XLI is poorly-characterised, and the behavioural profile of adults with XLI has not yet been documented at all.Using an online survey, advertised worldwide, we collected detailed self- or parent-reported information on behaviour in adult (n = 58 and younger (≤18yrs, n = 24 males with XLI for comparison to data from their non-affected brothers, and age/gender-matched previously-published normative data. The survey comprised demographic and background information (including any prior clinical diagnoses and validated questionnaires assaying phenotypes of particular interest (Adult ADHD Self-Report Scale v1.1, Barrett Impulsiveness Scale-11, adult and adolescent Autism Quotient, Kessler Psychological Distress Scales, and Disruptive Behaviour Disorder Rating Scale.Individuals with XLI generally exhibited normal sensory function. Boys with XLI were at increased risk of developmental disorder, whilst adults with the condition were at increased risk of both developmental and mood disorders. Both adult and younger XLI groups scored significantly more highly than male general population norms on measures of inattention, impulsivity, autism-related traits, psychological distress and disruptive behavioural traits.These findings indicate that both adult and younger males with XLI exhibit personality profiles that are distinct from those of males within the general population, and suggest that individuals with XLI may be at heightened risk of psychopathology. The data are consistent with the notion that STS is important in neurodevelopment and ongoing brain function, and with previous work suggesting high rates of

Money boys with inconsistent condom use (less than 100% of the time) are at high risk of infection by human immunodeficiency virus (HIV) or sexually transmitted infection (STI), but relatively little research has examined their risk behaviors. We investigated the prevalence of consistent condom use (100% of the time) and associated factors among money boys. A cross-sectional study using a structured questionnaire was conducted among money boys in Changsha, China, between July 2012 and January 2013. Independent variables included socio-demographic data, substance abuse history, work characteristics, and self-reported HIV and STI history. Dependent variables included the consistent condom use with different types of sex partners. Among the participants, 82.4% used condoms consistently with male clients, 80.2% with male sex partners, and 77.1% with female sex partners in the past 3 months. A multiple stepwise logistic regression model identified four statistically significant factors associated with lower likelihoods of consistent condom use with male clients: age group, substance abuse, lack of an "employment" arrangement, and having no HIV test within the prior 6 months. In a similar model, only one factor associated significantly with lower likelihoods of consistent condom use with male sex partners was identified in multiple stepwise logistic regression analyses: having no HIV test within the prior six months. As for female sex partners, two significant variables were statistically significant in the multiple stepwise logistic regression analysis: having no HIV test within the prior 6 months and having STI history. Interventions which are linked with more realistic and acceptable HIV prevention methods are greatly warranted and should increase risk awareness and the behavior of consistent condom use in both commercial and personal relationship. © 2015 International Society for Sexual Medicine.

On the basis of the widespread belief that emotions underpin psychological adjustment, the authors tested 3 predicted relations between externalizing problems and anger, internalizing problems and fear and sadness, and the absence of externalizing problems and social-moral emotion (embarrassment). Seventy adolescent boys were classified into 1 of 4 comparison groups on the basis of teacher reports using a behavior problem checklist: internalizers, externalizers, mixed (both internalizers and externalizers), and nondisordered boys. The authors coded the facial expressions of emotion shown by the boys during a structured social interaction. Results supported the 3 hypotheses: (a) Externalizing adolescents showed increased facial expressions of anger, (b) on 1 measure internalizing adolescents showed increased facial expressions of fear, and (c) the absence of externalizing problems (or nondisordered classification) was related to increased displays of embarrassment. Discussion focused on the relations of these findings to hypotheses concerning the role of impulse control in antisocial behavior.

To identify impact of television viewing on language development. The case-control study included 56 new patients with language delay and 110 normal children, aged 15-48 months. Language delay was diagnosed by reviewing language milestones and Denver-II. Television viewing variables and child/parental characteristics between both groups were interviewed. The data were analyzed by ANOVA and chi-square test. Adjusted odds ratios and 95% confidence intervals were calculated from multivariate logistic regression model. Forty-six boys and 10 girls; mean [+/-SD] age, 2.11+/-0.47 years of the case group and 59 boys and 51 girls; mean [+/-SD] age, 2.23+/-0.80 years of the control group were enrolled. Children who had language delay usually started watching television earlier at age 7.22+/-5.52 months vs. 11.92+/-5.86 months, p-valuetelevision than normal children (3.05+/-1.90 h/day vs. 1.85+/-1.18 h/day; p-valuetelevision attelevision>2 h/day were approximately six times more likely to have language delays. There is a relationship between early onset and high frequency of TV viewing and language delay.

A thorough understanding of injury mechanisms and game situations associated with concussions in boys' high school lacrosse is necessary to target injury prevention efforts. To characterize common game-play scenarios and mechanisms of injury associated with concussions in boys' high school lacrosse using game video. Descriptive epidemiological study. In 25 public high schools of a single school system, 518 boys' lacrosse games were videotaped by trained videographers during the 2008 and 2009 seasons. Video of concussion incidents was examined to identify game characteristics and injury mechanisms using a lacrosse-specific coding instrument. A total of 34 concussions were captured on video. All concussions resulted from player-to-player bodily contact. Players were most often injured when contact was unanticipated or players were defenseless (n = 19; 56%), attempting to pick up a loose ball (n = 16; 47%), and/or ball handling (n = 14; 41%). Most frequently, the striking player's head (n = 27; 79%) was involved in the collision, and the struck player's head was the initial point of impact in 20 incidents (59%). In 68% (n = 23) of cases, a subsequent impact with the playing surface occurred immediately after the initial impact. A penalty was called in 26% (n = 9) of collisions. Player-to-player contact was the mechanism for all concussions. Most commonly, injured players were unaware of the pending contact, and the striking player used his head to initiate contact. Further investigation of preventive measures such as education of coaches and officials and enforcement of rules designed to prevent intentional head-to-head contact is warranted to reduce the incidence of concussions in boys' lacrosse.
Swimming pool sanitation has largely been concerned with the microbiological quality of pool water, which is normally treated using a number of chlorine products. Recent studies have pointed to the potential hazards of chlorine by-products to the respiratory epithelium, particularly in indoor, poorly ventilated, pools. The aim of our study was to elucidate whether chronic exposure to indoor chlorinated swimming pools was associated with an increased likelihood of the development of asthma in boys. METHODS: The subjects were boys aged between 6 and 12 years. Data was collected by means of parental responses to a standardized asthma questionnaire (ISAAC: International Study of Asthma and Allergies in Childhood), supplemented with additional questions regarding frequency of attendance, number of years attendance, whether the child is a swimming team member. The questionnaire return rate was 71\\/% (n = 121). 23 boys were excluded on the basis that they had asthma before they started swimming (n = 97). There was a significant association between number of years a boy had been swimming and the likelihood of wheezing in the last 12 months (p = 0.009; OR = 1.351; 95% CI = 1.077-1.693) and diagnosed asthma (p = 0.046; OR = 1.299; 95% CI = 1.004-1.506). The greater the number the number of years a boy had been attending an indoor, chlorinated pool, the greater the likelihood of wheezing in the last 12 months or "had asthma". Age, parental smoking habits and being a swimming team member had no association with any of the asthma variables examined. Swimming pool attendance may be a risk factor in asthma in boys.

Full Text Available Objective. The aim of this study was to identify the prevalence of excess television time and verify correlated factors in adolescent males and females. Methods. This cross-sectional study included 2,105 adolescents aged from 13 to 18 years from the city of Aracaju, Northeastern Brazil. Television time was self-reported, corresponding to the time spent watching television in a typical week. Several correlates were examined including age, skin color, socioeconomic status, parent education, physical activity level, consumption of fruits and vegetables, smoking status, alcohol use, and sports team participation. Results. The prevalence excess television time (≥2 hours/day in girls and boys was 70.9% and 66.2%, respectively. Girls with low socioeconomic status or inadequate consumption of fruits and vegetables were more likely to have excess television time. Among boys, those >16 years of age or with black skin color were more likely to have excess television time. Conclusions. Excess television time was observed in more than two-thirds of adolescents, being more evident in girls. Correlated factors differed according to sex. Efforts to reduce television time among Brazilian adolescents, and replace with more active pursuits, may yield desirable public health benefits.

Full Text Available Background. A growing body of evidence suggests an association between altered hypothalamic-pituitary-adrenal axis reactivity and the development of persistent antisocial behavior in children. However the effects of altered cortisol levels remain poorly understood in the complex context of conduct disorder, callous-unemotional (CU personality traits, and frequent comorbidities, such as attention deficit hyperactivity disorder (ADHD. The aim of the current study was to investigate associations among CU traits, antisocial behavior, and comorbid ADHD symptomatology with cortisol levels in male children and adolescents. Methods. The study included 37 boys with early-onset conduct disorder (EO-CD, mean age 11.9 years and 38 healthy boys (mean age 12.5 years. Participants were subjected to multiple daytime salivary cortisol measurements and a psychometric characterization. Results. Subjects in the EO-CD group with elevated CU traits showed a diminished cortisol awakening response compared to healthy participants. In the EO-CD group, high CU traits and impulsivity were associated with decreased diurnal cortisol levels, while associations with antisocial behavior were not detected. The cortisol awakening response was significantly inversely associated with hyperactivity (P=0.02 and marginally significant with CU traits (P=0.07. Conclusions. These results indicate a specific association between CU traits and a diminished stress response, which is not explained by antisocial behavior in general.

Full Text Available When romantic encounters come to an end they often evoke a plethora of feelings associated with "breaking up". This article explores this issue in relation to a number of adolescent girls' views on this topic which emerged during focus group discussions about Eminem's song Foolish Pride. The lyrics of this song convey resentment towards an ex-girlfriend and accentuate racial elements which, in the words of the song, could be summed up as "Never date a Black girl because Blacks only want your money". Data were collected in two school settings, involving female students of different nationalities, in order to discover students' reactions to the provocative lyrics that demonstrate how meanings that surround the end of a romantic relationship are shaped and produced within the intersectionality of gender and race. A diffractive model of analysis is adopted to explore the girls' concerns with the misogynistic tone underlying this rap song. The girls' opposition to boys emerges as a central theme. Underlying this resistance however there was also an affirmation of heteronormative femininity. The girls' perspectives suggest that although students do not passively absorb racialised and heterosexualised constructions of gender, their apprehension of messages mediated through popular media could affirm the gender divide. It could also reinforce estrangements between teenage boys and girls that the media promotes.

Background Men comprise nearly two-thirds of trafficked and forced labourers in common low-skilled labour sectors including fishing, agriculture and factory work. Yet, most evidence on human trafficking has focused on women and girls trafficked for sex work, with scant research on trafficked men and boys. Methods We analyse survey data from the largest systematic consecutive sample of trafficked people collected to date to describe the prevalence of violence, occupational health risks and injuries and associated factors. Participants were labour-trafficked men and boys using post-trafficking support services in Thailand, Cambodia and Vietnam. Findings Data are presented on 446 males aged 10–58. Men and boys were mainly trafficked for fishing (61.7%), manufacturing (19.1%) and begging (5.2%). Fishermen worked extensive hours (mean 18.8 hours/day, SD 5.9) and factory workers worked on average 11.9 hours/day (SD 2.9). 35.5% of male survivors had been injured while trafficked; 29.4% received no personal protective equipment (e.g. gloves). The most commonly reported injuries among all males were deep cuts (61.8%) and skin injuries (36.7%), injuries for which fewer than one-quarter reported receiving medical care. Six fishermen lost body parts, none of whom received medical care. Most males (80.5%) had no or very few rest breaks. One-third (37.8%) experienced severe violence. Work-related injuries were associated with severe violence (AOR 3.44, CI:1.63–7.26), being in the fishing sector, (AOR 4.12, CI:2.39–7.09) and threats (AOR 2.77, CI:1.62–4.75). Experiencing any violence was associated with threats (AOR 26.86, CI:14.0–51.23), being in the fishing sector (AOR 18.53, CI:8.74–39.28) and fluency in language of destination country (AOR 0.39, CI:0.20–0.75).

In the food industry, injuries due to food poisoning have been increasing. Especially the mass outbreak of food poisoning by Escherichia coli such as O-157 in 1996 gave warning on the importance of food sanitation management. Public efforts such as the Hazard Analysis and Critical Control Point (HACCP) system have been made to prevent food poisoning. Recently, disinfection made by electrolyzing water with some salt added has attracted attention. Fuji Electric has developed the generator 'SaniBoy' that produces weak alkaline electrolyzed water without wasting water. The environment-friendly 'SaniBoy' will contribute to sanitation in various fields. (author)

This study examined the contribution of general normative beliefs about aggression and specific normative beliefs about retaliatory aggression in predicting physical, verbal, and indirect aggressive behaviors. Two hundred and forty-nine Grade 4 and Grade 5 boys completed the Normative Beliefs about Aggression Scale (NOBAGS) and provided self-reports on the frequency of their physical, verbal, and indirect aggressive behaviors. A series of hierarchical multiple regression analyses revealed that general normative beliefs about aggression contributed significantly in predicting all three types of aggressive behaviors. When general normative beliefs about aggression were controlled for, specific normative beliefs about retaliatory aggression against males but not specific normative beliefs about retaliatory aggression against females, contributed significantly to predict physical, verbal, and indirect aggressive behaviors. Implications for intervention programs are discussed.

Full Text Available Miss Evers' Boys (1997 is a movie based on a real fact happened in the State of Alabama (United States, where it was carried out a research work that begun in 1932 and was prolonged up to 1972. It consisted on watching the evolution of syphilis in black male patients, who were not given any anti-syphilitic treatment at any moment. Once the fact was public, a great polemic on the ethics of the research with human fellows was originated and publications dealt with this case. The movie, faithful as for the bottom of the problem, it’s made as a novel about a research team’s nurse and four black participants patients.

To assess the value of the lateral view in the diagnosis of pleural plaques, 2018 chest roentgenograms from the general population were scrutinized for such plaques. The lateral and posterior-anterior (PA) views were read separately and without knowledge of the occupational history or other clinical data. Of the males, 4.8% had pleural plaques in the PA view and 2% had dorsal pleural plaques in the lateral view. A total of 54% of the positive cases in the PA view also showed typical plaques in the PA view. Thus, there remained a number of cases which were diagnosed only in the lateral view; in all, these constituted 18.8%

Initiation and progression of puberty requires concerted action of hypothalamic activating and inhibiting factors. Recently, cases of familial central precocious puberty have been linked to loss-of-function mutations of makorin RING-finger protein 3 (MKRN3) indicating a pivotal inhibitory role of the protein on GnRH secretion. To investigate peripubertal circulating MKRN3 levels in healthy boys. Population-based longitudinal study in healthy Danish boys. General community. Healthy boys (n = 60) aged (median [range]) 9.3 (5.8-11.8) years at baseline followed for 6.0 (0.5-7.6) years (2006-2014) with blood sampling every 6 months. None. Serum levels of MKRN3: 623 samples, median (range) 12 (2-14) per boy. MKRN3 levels declined before onset of puberty; the geometric mean (95% confidence interval) 5 years before onset of puberty vs last visit before onset of puberty was 216 (169-272) pg/mL vs 128 (118-139) pg/mL (P puberty progressed. MKRN3 levels were not associated with age at onset of puberty. Declining MKRN3 before pubertal onset support MKRN3 as an inhibitor of GnRH secretion during midchildhood.

In developed societies levels of daily physical activity (PA) among school-age children are decreasing. This implies risk factors for cardiovascular and metabolic diseases. Specific strategies to improve levels of PA are needed. In prepubertal boys there is evidence that strength training increases spontaneous PA outside of training. A total of 102 schoolchildren (age 10-14 years) in Switzerland were randomly assigned to physical education classes or to participate twice weekly at a guided strength training program for 19 weeks. Spontaneous PA energy expenditure (PAEE; 3axial accelerometry for 7 days), leg and arm strength, and body composition (dual energy radiograph absorptiometry) were measured at baseline, after 19 weeks of training intervention, and after 3 months of washout. There were no significant differences between the groups at baseline. In the intervention group, PAEE increased by 10% from baseline to end of training in boys (P = .02), but not in girls. Leg and arm strength were increased owing to training intervention in both boys and girls. All other variables were unchanged. Baseline PAEE was significantly negatively correlated with changes of PAEE. Targeted strength training significantly increases daily spontaneous PA behavior in boys. The less active children showed the greatest increase in spontaneous PAEE. Girls showed a similar increase in strength, but not in spontaneous PAEE. This may be explained by their earlier pubertal development. Strength training may be a promising strategy in schools to counteract decreasing levels of PA.

The aim of this study was to examine the associations between lifetime traumatic experiences and leisure physical inactivity among adolescent boys and to determine to what extent those associations are mediated by posttraumatic stress symptoms, unhealthy behaviors (smoking, alcohol use), the daily consumption of fresh fruit, and sense of coherence. A self-administered questionnaire combining 3 instruments measured leisure physical activity level (Godin and Shephard), symptoms of posttraumatic stress (IES-revised), lifetime traumatic experiences, sense of coherence (SOC-13, from Antonovsky), and behavioral and dietary patterns in a representative sample of eighth grade boys from a number of Kaunas, Lithuania, secondary schools (N = 885; response rate 88.6%). Fifty-six point eight percent of boys had experienced at least 1 lifetime traumatic event, with a 20.5% prevalence of PTS symptoms, and 5.4% were inactive during leisure time. In the logistic regression models, leisure physical inactivity was associated with lifetime traumatic experiences (adjusted OR = 2.33; 95% CI: 1.09-4.98). Sense of coherence and posttraumatic stress symptoms did not mediate those associations. Less-than-daily consumption of fresh fruit showed an independent effect, while smoking and weekly consumption of alcohol did not. Consistent associations between lifetime traumatic experiences and leisure physical inactivity among adolescent boys indicate that the presence of lifetime traumatic events should be taken into account when employing intervention and prevention programs on unhealthy lifestyles (physical inactivity, smoking, and alcohol).

Quality of life has been conceptualized as a subjective view of one's feeling of well-being. There is evidence for restraints caused by parenting stress as well as resilience in mothers of children with an intellectual handicap. Specifically, we report on an investigation using the family-related life quality questionnaire (FLQ) in mothers of 26 young boys with Fragile X syndrome. Quality of life is affected by parenting stress as well as individual and social coping resources (hope as a personal trait and quality of family relationships). Child-related variables (age, adaptive competence) had no significant effect on perceived quality of life, child temperament and atypical behavior is related indirectly to maternal life satisfaction as a factor determining the degree of parenting stress.

The role of peer harassment in the association between sexual minority status and adolescent risky behavior was examined for 15-year-olds in the NICHD Study of Early Child Care and Youth Development (n = 957). The findings, although exploratory, suggest the importance of gender. For girls, peer harassment was best viewed as a moderator of the link between sexual minority status and increased risky behavior. It intensified an existing association, reflecting the gendered nature of the impact of sexual minority status on the adolescent social context. For boys, peer harassment was primarily a mediator, such that sexual minority status was associated with more risky behavior via elevated harassment, although sexual minority status itself was associated with lower risky behavior overall.

Full Text Available Objective: To explore whether the symptoms and diagnosis of Oppositional Defiant Disorder (ODD, as defined in the DSM-IV, are equally impairing for girls and boys from the general population in the early school years. Method: A sample of 852 three to seven-year-old schoolchildren were screened out for a double-phase design. A total of 251 families were assessed with a diagnostic interview and with measures of functional impairment. Results: ODD symptoms and diagnosis were equally prevalent in boys and girls, but three to five-year-old girls had a higher prevalence of subthreshold ODD. There were no significant differences between boys and girls in the impact on use of services, treatment received and family burden associated with ODD symptoms and diagnosis. Although diagnosis of ODD was not associated with higher functional impairment by sex, individual symptoms and subthreshold diagnosis were more impairing for boys than for girls. Conclusion: Oppositionality may be measuring different things for boys and girls, and this possibility must be taken into account with a view to the correct identification of this problem in each sex.

This study examined the association between childhood ADHD and juvenile delinquency by examining data from the Pittsburgh ADHD Longitudinal Study (PALS), a follow-up study of individuals diagnosed with ADHD in childhood (ages 5-12) and recontacted in adolescence and young adulthood for yearly follow-up (age at first follow-up interview M = 17.26, SD = 3.17). Participants were 288 males with childhood ADHD and 209 demographically similar males without ADHD who were recruited into the follow-up study. Delinquency information gathered yearly during the second through eighth follow-up provided a comprehensive history of juvenile delinquency for all participants. Four childhood diagnostic groups [ADHD-only (N = 47), ADHD + ODD (N = 135), ADHD + CD (N = 106), and comparison (N = 209)] were used to examine group differences on delinquency outcomes. Analyses were conducted across three dimensions of delinquency (i.e., severity, age of initiation, and variety). Individuals with childhood ADHD + CD displayed significantly worse delinquency outcomes than the other three groups, across almost all indices of offending. When compared to comparison participants, boys with ADHD-only and ADHD + ODD in childhood displayed earlier ages of delinquency initiation, a greater variety of offending, and higher prevalence of severe delinquency. These findings suggest that although childhood ADHD + CD creates the greatest risk for delinquency, boys with ADHD-only and ADHD + ODD also appear at a higher risk for later offending. The patterns of offending that emerged from the PALS are discussed in the context of the relationship between ADHD, comorbidity, and delinquency.

The problem of the high prevalence of smoking among girls and young women is of great concern. In an attempt to identify the factors which influence girls and boys respectively to attempt smoking, the study examines social background, advertising and brand awareness, knowledge, teaching and personal beliefs in conjunction as predictors of smoking. In this study which involved the administration of identical pre- and post-test questionnaires to a sample of boys and girls aged 12 and 13 years, nine variables expressed by never-smokers at pre-test stage were assessed as predictors of immediate future smoking. The two tests were administered 4 months apart to 1125 boys and 1213 girls in northern England. The nine variables included were parental smoking, best friends' smoking, perceived positive values of smoking, perceived negative values of smoking, correct health knowledge, cigarette-brand awareness, having a favourite cigarette advertisement, having a cigarette-brand sponsored sport in four top favourites on television. One group received teaching about smoking between the pre- and post-tests and this was also included as a variable. For boys, no variable investigated had any consistently statistically significant correlation with the uptake of smoking. The most important predictor of smoking for boys, having a best friend who smoked, was significant on application of the chi 2 test (P 0.037), although it was non-significant when included singly in a logistic regression model (0.094); the discrepancy was probably due to the small number of best friends known to smoke. For girls, four variables were found to be significant predictors of smoking when included singly in a logistic regression.(ABSTRACT TRUNCATED AT 250 WORDS)
Full Text Available Sam ShusterNewcastle University, Newcastle Upon Type, NE1 7RU, UKAbstract: The response to seeing a man riding a unicycle was reported to be consistently related to the viewer's sex and stage of physical development. To see if this observation was universal, observations of responses were collected from 23 male and 9 female unicyclists aged 15–69 years, with 2–40 years cycling experience across four continents. With two exceptions among men, the findings were the same as those originally reported: children showed interest and curiosity, young girls showed little interest, while adult women showed a kindly, concerned, praising response. By contrast, boys showed physical aggression, which became more verbal, merging in the later teens to the snide, aggressive, stereotyped humorous response shown by adult males, which became less frequent in elderly men. The universality of the response across different individuals, environments, and dates of observation suggests an endogenous mechanism, and the association with masculine development relates this to androgen. The theoretical consequences are discussed. It is concluded that humor develops from aggression in males and is evolutionarily related to sexual selection.Keywords: humor evolution, male aggressive behavior

The prostate gland plays an important role in male reproduction. Inflammation of the prostate gland (prostatitis) is a common health problem affecting many young and middle aged men. Prostatitis is considered a correctable cause of male infertility, but the pathophysiology and appropriate treatment options of prostatitis in male infertility remain unclear. This literature review will focus on current data regarding prostatitis and its impact on male infertility. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

To use ecological momentary assessment to describe how adolescent boys in the United Kingdom spend their leisure time. Design. Cross-sectional, stratified, random sample from secondary schools in 15 regions within the United Kingdom. The data are from a larger study of adolescent lifestyles (Project STIL). A total of 561 boys with a mean age of 14.6 years (range 12.7-16.7 years). The majority were white-European (86.5%). Television viewing occupied the most leisure time on both weekdays (131 minutes) and weekend (202.5 minutes) days. On weekdays the five most time consuming sedentary activities (television viewing, homework, motorised travel, playing computer/video games and shopping/hanging out) occupied on average 272.2 minutes. On weekend days, the five most time consuming sedentary activities (television viewing, shopping/hanging out, motorised travel, sitting and talking and playing computer/video games) occupied 405.5 minutes. In total, 54 minutes were occupied by active transport or sports and exercise per weekday and 81 minutes per weekend day. Only a minority watched more than 4 hours of TV per day (8.9% on weekdays and 33.8% on weekend days). Differences were noted in the means and prevalence between weekend and weekdays, reflecting the greater discretionary time available at the weekend. Adolescent boys engage in a variety of sedentary and active free time behaviours. It appears prudent to encourage adolescents to adopt overall healthy lifestyles by considering the combination of both active and sedentary pursuits an individual engages in and by moving beyond a focus on any one single behaviour.

Full Text Available Abstract Background The Australian Longitudinal Study on Male Health (Ten to Men was established in 2011 to build the evidence base on male health to inform policy and program development. Methods Ten to Men is a national longitudinal study with a stratified multi-stage cluster random sample design and oversampling in rural and regional areas. Household recruitment was conducted from October 2013 to July 2014. Males who were aged 10 to 55 years residing in private dwellings were eligible to participate. Data were collected via self-completion paper questionnaires (participants aged 15 to 55 and by computer-assisted personal interview (boys aged 10 to 14. Household and proxy health data for boys were collected from a parent via a self-completion paper-based questionnaire. Questions covered socio-demographics, health status, mental health and wellbeing, health behaviours, social determinants, and health knowledge and service use. Results A cohort of 15,988 males aged between 10 and 55 years was recruited representing a response fraction of 35 %. Conclusion Ten to Men is a unique resource for investigating male health and wellbeing. Wave 1 data are available for approved research projects.

Children with language impairment (LI) experience social difficulties, including conflict management. This paper is therefore motivated to examine behavioural processes guiding preschool peer conflict progression, which ultimately contributes to overall development. To describe behavioural sequences in conflicts between children with typically developing language (TL) and between children with LI. Attention is particularly focused on the conflict resolution strategy reconciliation, i.e. friendly contact between former opponents shortly following conflict termination. It is hypothesized that children with LI, with weaker language skills, experience difficulties attaining effective reconciliation. Unstructured play of 11 boys with LI (4-7-years-old), at a specialized language preschool, and 20 TL boys (4-6-years-old), at mainstream preschools, were video filmed. Conflicts were identified and recorded according to a validated coding system. Recorded conflict details included behavioural sequences constituting conflict cause (conflict period) and in the post-conflict period, reconciliatory behaviours that were classified into six 'categories' (Invitation to play, Body contact, Object offer, Verbal apology, Self-ridicule, Cognition, i.e. offering privileges/negotiating) and the verbal character of accepted behaviours were determined. The mean proportion of individual target children's conflicts in which specific behavioural sequences had occurred were calculated and thereafter compared between and within the groups. Boys with LI reconcile fewer conflicts than TL boys (LI: 47.3 +/- 4.5%; TL: 63.6 +/- 2.0%). Contributory factors include the occurrence of conflicts caused by aberrance, i.e. conflicts initiated by inappropriate behavioural play intensities (i.e. 'a pillow fight' where one partner swings so intensively the other partner cannot participate as a player in the game) and protests that are no longer directed to the opponent within reciprocal exchanges, but

In recent years, suicide rates have increased in adolescents and the young population, so these age groups are considered as populations at risk. Considering that suicidal ideation is the first sign of possible future suicide behavior, the objective of this study is to determine the relative importance of psychological maturity, personality, depression and life satisfaction in predicting suicidal ideation in adolescents. Results show that depressive symptoms is the variable that best predicts suicidal ideation, but psychological maturity, life satisfaction and emotional stability are predictors as well (R2 = .51, p emotional stability has an indirect relationship with suicidal ideation, through its relationship with depressive symptoms, life satisfaction and identity. Two Multigroup Structural Equation Models were proposed to better understand the relationships between these variables for each sex. The results show that the fit of the model that includes the variable Self-reliance is better for boys than for girls (chi-square contributions of 8.175 for girls and 1.978 for boys) unlike the other model (chi-square contributions of 0.288 for girls and 1.650 for boys). These results suggest that the psychological maturity subscale Self-reliance play a role in suicidal ideation in males but not in females. Although there have been no previous studies on the role of psychological maturity as a predictor of suicidal phenomena, the current study suggests that it is a feature to be considered in the prediction of adolescent suicidal ideation.

Purpose To examine how the associations among BMI and body dissatisfaction and weight and shape concern evolve from late childhood through late adolescence in boys and girls. Methods We analyze data from 9–18-year-olds from the Growing Up Today Study, a national prospective cohort of U.S. Youth (n= 16,882, yielding 59,750 repeated measures observations during five waves of data collection). Generalized additive models produced curves of association for body dissatisfaction and weight concern across BMI percentiles. Generalized estimating equations (adjusting for correlated within-subject repeated measures, sibling clusters, pubertal maturation, and region of residence) tested main and interactive effects of BMI, age, and gender. Results Girls above the 50th BMI percentile reported greater body dissatisfaction than girls below the 50th percentile. By contrast, boys who reported the most body dissatisfaction were either above the 75th BMI percentile (approaching overweight) or below the 10th percentile (approaching underweight). Body dissatisfaction increased with age for both girls and boys, but the gender-specific patterns of BMI effects remained constant. Male and female participants in the overweight/obese BMI range reported the greatest weight concern, but among older adolescents (particularly girls), healthy weight became increasingly associated with greater weight and shape concern. Conclusions Body dissatisfaction and weight and shape concern intensify across adolescence, but associations between the constructs and BMI remain gender-specific. Findings have important implications for eating disorder risk assessment and prevention. PMID:23084175

Increased food intake (FI) during television viewing has been reported in children, but it is unknown if this occurs following pre-meal video game playing (VGP). The objective was to determine the effect of pre-meal VGP for 30 min on subjective appetite and emotions, and FI in normal weight (NW) boys after a glucose or control preload. On four test mornings, NW boys (n = 19) received equally sweetened preloads of a non-caloric sucralose control or 50 g glucose in 250 mL of water, with or without VGP for 30 min. Food intake from an ad libitum pizza meal was measured immediately after. Subjective appetite was measured at 0, 15, 30, and 60 min. Subjective emotions were determined by visual analog scale at baseline and immediately before lunch. Both VGP (p = 0.023) and glucose (p aggression scores increased after VGP (p <0.05), but did not correlate with FI. However, baseline and pre-meal happiness and excitement scores were inversely associated with FI. In conclusion, both pre-meal VGP and the glucose preload suppressed FI, supporting the roles of both physiologic and environmental factors in the regulation of short-term FI in 9- to 14-year-old NW boys.

The United States current incarcerates more citizens than any other country in history, by disproportionately targeting men and boys of color through mechanisms such as the school to prison pipeline. In better understanding the processes that fuel the school to prison pipeline such as criminalizing practices and the ways boys of color resist them, we can begin to identify teaching practices and perspectives which work to disrupt those processes. Examining criminalization and acts of resistance in STEM education is particularly salient because of the high social and economic status STEM knowledge bears in dominant U.S. culture, and the ways access to STEM learning functions as gateways in our education system. Through a longitudinal study in a multi-site elementary after-school STEM program, I examined what criminalization and acts of resistance look like, the ways they interact, and how staff in the program work to disrupt those cycles. I found that criminalization and acts of resistance are normal and ordinary occurrences, frequently interacting in response to each other in escalating patterns. I also found that staff engaged in multiple categories of decriminalizing practices based on highly respectful interactions and viewing boys of color as brilliant students who engage in acts of resistance as a healthy response to oppressive measures.

The purpose of this study was to validate derived T2 maps as an objective measure of muscular fat for discrimination between boys with Duchenne muscular dystrophy (DMD) and healthy boys. Forty-two boys with DMD (mean age, 9.9 years) and 31 healthy boys (mean age, 11.4 years) were included in the study. Age, body mass index, and clinical function scale grade were evaluated. T1-weighted MR images and T2 maps with and without fat suppression were obtained. Fatty infiltration was graded 0-4 on T1-weighted images, and derived T2 fat values (difference between mean T2 values from T2 maps with and without fat suppression) of the gluteus maximus and vastus lateralis muscles were calculated. Group comparisons were performed. The upper limit of the 95% reference interval of T2 fat values from the control group was applied. There was no significant difference in age or body mass index between groups. All healthy boys and 19 boys (45.2%) with DMD had a normal clinical function scale grade. Grade 1 fatty infiltration was seen in 90.3% (gluteus maximus) and 71.0% (vastus lateralis) of healthy boys versus 33.3% (gluteus maximus) and 52.4% (vastus lateralis) of boys with DMD. T2 fat values of boys with DMD were significantly longer than in the control group (p < 0.001). Using a 95% reference interval for healthy boys for the gluteus maximus (28.3 milliseconds) allowed complete separation from boys with DMD (100% sensitivity, 100% specificity), whereas the values for the vastus lateralis (7.28 milliseconds) resulted in 83.3% sensitivity and 100% specificity. Measurement of muscular fat with T2 maps is accurate for differentiating boys with DMD from healthy boys.
Full Text Available Male-mediated developmental toxicity has been of concern for many years. The public became aware of male-mediated developmental toxicity in the early 1990s when it was reported that men working at Sellafield might be causing leukemia in their children. Human and animal studies have contributed to our current understanding of male-mediated effects. Animal studies in the 1980s and 1990s suggested that genetic damage after radiation and chemical exposure might be transmitted to offspring. With the increasing understanding that there is histone retention and modification, protamine incorporation into the chromatin and DNA methylation in mature sperm and that spermatozoal RNA transcripts can play important roles in the epigenetic state of sperm, heritable studies began to be viewed differently. Recent reports using molecular approaches have demonstrated that DNA damage can be transmitted to babies from smoking fathers, and expanded simple tandem repeats minisatellite mutations were found in the germline of fathers who were exposed to radiation from the Chernobyl nuclear power plant disaster. In epidemiological studies, it is possible to clarify whether damage is transmitted to the sons after exposure of the fathers. Paternally transmitted damage to the offspring is now recognized as a complex issue with genetic as well as epigenetic components.
Doctors specializing in male contraception are aware of the very real difficulties hindering the development of an effective method in this field. Others believe that the reason this type of contraception is lagging behind is male chauvinism or a certain fear that men have of losing their virility along with their fertilizing capacity. Since available methods of contraception (condom, vasectomy) have low levels of acceptability and reversibility, research has proceeded along other avenues. 1) Gossypol reduces the number and motility of spermatozoa but its general side effects are not exceptional. 2) Restraining hormonal action (progrestogens, LH-RH agonists) also reduce testicular function and for this reason, require simultaneous administration of androgens. Thus far this has not been resolved; azoospermia is not obtained in every case and when it is, it does not necessarily last. 3) A method involving the epididymis, with a view to preventing spermatozoa from acquiring their normal motility and fertilizing capacity by affecting protein and enzyme synthesis, is also being studied. Perhaps, as has been suggested by the Bicetre Hospital research team, we should be content with methods applicable to certain categories of men. Male contraception would then develop step by step rather than by huge bounds as female contraception. full text

The adverse effect profiles of typical and atypical antipsychotics are problematic because of their extrapyramidal and endocrine adverse effects, respectively. Ten adolescent male patients diagnosed with conduct disorder received aripiprazole in doses of ≤20 mg/d in an open-label, intent-to-treat design to establish and characterize the efficacy of the drug in reducing aggressive behavior. Based on clinician and parent observations, aripiprazole was effective in reducing aggressive behavior in adolescent boys. The change in clinician-observed aggression ratings appears to have been driven by a decrease in physical aggression, whereas the change in parent-observed aggression ratings appears to have been driven by a decrease in verbal aggression and aggression against objects and animals. Aripiprazole was an effective and relatively well-tolerated treatment for overall aggression in adolescent males with conduct disorder, in the view of both clinicians and parents. Depending on the observer, aripiprazole improved aggression categorized as physical aggression, verbal aggression, and aggression against objects and animals.

Confirmatory factor analysis of responses to the Male Role Norms Inventory-Adolescent-revised (MRNI-A-r) from 384 middle school students (163 boys, 221 girls) indicated that the best fit to the data was a bifactor model incorporating the hypothesized 3-factor structure while explicitly modeling an additional, general factor. Specifically, each item-level indicator loaded simultaneously on 2 factors: a general traditional masculinity ideology factor and a specific factor corresponding to 1 of the 3 hypothesized masculine norms for adolescents: Emotionally Detached Dominance, Toughness, and Avoidance of Femininity. Invariance testing across gender supported metric invariance for the general factor only. Although item loadings on the general factor were similar across boys and girls, the specific factor loadings varied substantially, with many becoming nonsignificant in the presence of the general factor for girls. A structural regression analysis predicting latent variables of the Meanings of Adolescent Masculinity Scale (MAMS), the Rosenberg Self-esteem Scale, and the Discipline, School Difficulties, and Positive Behavior Scale (DSDPBS) indicated that the general factor was a strong predictor of MAMS for both genders and DSDPBS for girls. Findings indicate that the MRNI-A-r general factor is a valid and reliable indicator of overall internalization of traditional masculinity ideology in adolescents; however, the specific factors may have different meanings for boys as compared with girls and lack validity in the presence of the general factor. These findings are consistent with a developmental perspective of gender ideology that views adolescence as a time when a differentiated cognitive schema of masculine norms is beginning to develop.

performance value were scored higher in women, self-confidence and procrastination higher in men. Because TASTE didn't discriminate the different components of motivation (performance value referred to intrinsic and extrinsic motivations without precise distinction) we decided to use the MPS (Multidimensional Perfectionism Scale) which gave the opportunity to distinguish SOP (Self Oriented Perfectionism) ie, the self-imposed unrealistic standards with inability to accept faults in order to know and master a subject, that corresponded to intrinsic motivation; SPP (Socially Prescribed Perfectionism) ie, the exaggerated expectancies of others which are subjectively believed as imposed and uncontrollable leading to anxiety, feelings of failure or helplessness, that corresponded to extrinsic motivation; POO (Perfectionism Oriented to Others) ie, the unrealistic demands expected from significant others, which especially characterized males. We assumed that women attached more importance to succeed and submitted more to society exigencies. That way extrinsic and intrinsic motivations were probably more combined unlike men who, dreading a loss of self esteem, tried to avoid failure responsibility in using self handicapping or aggressive behaviours, so separating motivation in an extrinsic part turned to performance value and an intrinsic one more concerned by self confidence and sense of competence with the result that the motivational balance was surely disrupted in case of high competition leading to failure or avoidance. In another previous study we established a structural model illustrating, according to gender, correlations between anxiety, sense of incompetence, self-oriented perfectionism and socially prescribed perfectionism. Self-oriented perfectionism was less correlated to socially prescribed perfectionism in boys than in girls; furthermore especially by those who had never failed, it was negatively correlated to sense of incompetence, thus leading to lower scores of

Full Text Available A 5-year-old boy was presented with a recurrent history of fractures since the age of 3 years. He had 2–3 admissions per year due to fall and had a history of fractures at his right ankle, left femur and three times at his left elbow. On further questioning, it was found that he was born via spontaneous vaginal delivery. Antenatal and postnatal periods were uneventful and neonatal and development histories were similar to other siblings. No similar illnesses, history of osteoporosis, recurrent fractures or eye problem were found in the family. Examination showed that he was a thin-built boy with a normal gait, vision, speech and hearing. It was noted he had an eye abnormality (Figure 1, but the ear, nose, throat and dentition were normal. The cranial nerve and other neurological tests were also normal. There was no joint hypermobility and the other systems and pure tone audiogram were normal.
Depression is a serious mental health problem that affects people of all ages, including children and adolescents. Studies showed that female gender is one of the risk factors may influence the development of depression in adolescents. However, some of the studies from Turkey suggested that gender does not lead to any significant difference in the youth depression level. Therefore, the presented study investigated whether girls differ from boys in respect of depression. T...

A 12-year-old boy returned from a summer holiday in North Morocco with a slowly progressive erythematous, infiltrated plaque with a central crust on his right cheek. We diagnosed this as cutaneous leishmaniasis. Treatment for Leishmania major infection failed; subsequent PCR species typing revealed Leishmania infantum. This case shows the importance of recognition of parasitic skin diseases in travellers to the nearby subtropics and the value of leishmania species typing.
In Canada, boys account for almost three quarters of suicides among those aged 15-24 years. However, non-fatal suicide-related behaviours also onset in youth but are more common in girls. Thus far, there has been little empirical investigation of what produces this gender paradox. This report summarizes two recently published studies in which ICES tackles the issues of the potential impacts of misclassification of suicide and of help-seeking behaviour.

Full Text Available The current study of preschool children characterizes a semi-natural extension of experimental questions on how human ancestors evaded predation when encountering dangerous felids. In a pretend game on a playground, we presented full-size leopard and deer models to children (N = 39 in a repeatedmeasures experimental design. Prior to viewing the model presented 15-m away, each child was instructed by the experimenter to go where she or he would feel safe. The rationale for this study was based on the anthropological construct of “sexual dinichism,” positing that, during the Pliocene, smaller-bodied hominin females engaged in more arboreal behavior than larger-bodied males. Consistent with this construct, our previous simulation research using images of an African rock outcrop showed that, after viewing a lion, girls preferred a tree as refuge rather than a crevice or large boulder whereas boys did not differentiate these refuge sites. In this follow-up study, we predicted that, after viewing the model leopard, the preschool girls would differ from the boys by not choosing enclosed refuge sites analogous to the crevice. Analyses of a contingency table for the leopard model supported this hypothesis by yielding a significant interaction of sex and refuge location (p = .031, d = .76, the source of which was a reliably larger percentage of girls not choosing concealed refuge (p = .005, d = 2.3. The interaction of sex and refuge location for the model deer was not significant (p > .5. Our findings suggest that, in contrast to the deer, the girls selected exposed playground refuge sites rather than concealing ones to maintain visual contact with the leopard as a contingency for future action
The women's movement has shown how outdated assumptions about women block their freedom to achieve and stunt their earning power, but traditional stereotypes also exact a toll from men. Boys growing up in today's society must "prove" themselves to be full-fledged males, and are discouraged from being aesthetic, sensual, and nurturing. Athletics…

The response to seeing a man riding a unicycle was reported to be consistently related to the viewer's sex and stage of physical development. To see if this observation was universal, observations of responses were collected from 23 male and 9 female unicyclists aged 15-69 years, with 2-40 years cycling experience across four continents. With two exceptions among men, the findings were the same as those originally reported: children showed interest and curiosity, young girls showed little interest, while adult women showed a kindly, concerned, praising response. By contrast, boys showed physical aggression, which became more verbal, merging in the later teens to the snide, aggressive, stereotyped humorous response shown by adult males, which became less frequent in elderly men. The universality of the response across different individuals, environments, and dates of observation suggests an endogenous mechanism, and the association with masculine development relates this to androgen. The theoretical consequences are discussed. It is concluded that humor develops from aggression in males and is evolutionarily related to sexual selection.
Full Text Available Introduction. Psychological factors influence the morbidity and mortality from cardiovascular diseases to the same extent as demographic and clinical factors, and the effectiveness of treatment is significantly associated with the patients' adherence. Male gender is associated with poor blood pressure control. Aim. To identify the personality characteristics that determine compliance in adolescent boys with primary arterial hypertension. Materials and methods. 30 boys between 13 and 17 years old (average age 14.6 ± 1.1 years with primary arterial hypertension were examined. The compliance was evaluated using Girerd Questionnaire, type D (distress type personality - using the DS-14 test, personality features - using the Cattell's 16 Personality Factors Test (16PF. Statistical processing of the study results was conducted using dispersion, correlation and factor analysis (main components method with the help of “Statistica” software for Windows 8.0. Results. In 3.7% of adolescents, high compliance was noted, in 37.0% - moderate level, and in 59.3% - low. The type D personality was found in 20.0% of the examined boys. Patients with type D personality had a significantly lower (p<0.05 compliance (4.67 ± 0.63 versus 2.55 ± 0.36 points. There was found a significant direct correlation between the degree of compliance reduction and the scores on “social oppression” according to the DS-14 test (r = 0.43; p<0.01 and inverse correlation - with the value of factor N (straightforwardness-diplomacy of the 16PF (r = -0.43; p<0.05. There were found 3 main factors that explain almost 50% of the relationships of personality characteristics of boys with primary arterial hypertension. Factor 1 (distressing ability was related to the degree of compliance reduction (0.60, scales “negative excitability” (0.52 and “social oppression” (0.66 of the DS-14 test.

Delinquent adolescents are a known high-risk group for later criminality. Cognitive deficits correlate with adult criminality, and specific cognitive deficits might predict later criminality in the high-risk adolescents. This study aimed to explore the neuropsychological performance and predictors of adult criminal offending in adolescents with severe behavioural problems. Fifty-three adolescents (33 boys and 20 girls), aged 15-18 years, residing in a reform school due to serious conduct problems, were examined for neuropsychological profile and psychiatric symptoms. Results were compared with a same-age general population control sample, and used for predicting criminality 5 years after the baseline testing. The reform school adolescents' neuropsychological performance was weak on many tasks, and especially on the verbal domain. Five years after the baseline testing, half of the reform school adolescents had obtained a criminal record. Males were overrepresented in both any criminality (75% vs. 10%) and in violent crime (50% vs. 5%). When cognitive variables, psychiatric symptoms and background factors were used as predictors for later offending, low verbal intellectual ability turned out to be the most significant predictor of a criminal record and especially a record of violent crime. Neurocognitive deficits, especially in the verbal and attention domains, are common among delinquent adolescents. Among males, verbal deficits are the best predictors for later criminal offending and violence. Assessing verbal abilities among adolescent population with conduct problems might prove useful as a screening method for inclusion in specific therapies for aggression management.

Gender role discrepancy (GRD), or nonconformity to socially prescribed gender roles, has been linked to a multitude of adverse mental and behavioral health outcomes. Masculine discrepancy stress (MDS), stress about being perceived not to conform to one's gender role, may explain the relationship between GRD and deleterious health outcomes. However, research on MDS has primarily been restricted to adult males. This leaves a critical gap pertaining to the potential effect of MDS on adolescent boys, who may be more malleable and susceptible to the influence and pressures of gender socialization. In the current study, data are drawn from a sample of adolescent male students ( N = 592) who completed self-report questionnaires. We employed structural equation modeling to test the effects of GRD and MDS on psychosocial maladjustment measured via sexual behavior, substance use, violence, mood disorder symptoms, and hopelessness. In addition, we controlled for critical risk factors including sociodemographic characteristics, adverse childhood experiences, trauma symptoms, and neighborhood disorganization. Findings indicate significant potentiating effects of MDS on maladjustment while there were direct protective effects of GRD. These data suggest that developing prevention strategies that incorporate social norms pertaining to gender socialization may have an impact on multiple behavioral and mental health problems.

Full Text Available The objective of this study was to determine anthropometric and physical fitnesscharacteristics of Brazilian male children and adolescents at the beginning of soccer training. Inthis study, 282 male soccer players ranging in age from 10 to 13 years were evaluated. The athletesparticipated in a formal soccer training program 3 times per week, with each training lasting 3hours. Anthropometric and physical fitness parameters were obtained. The boys were divided intoage classes and prevalence data were analyzed using Pearson’s chi-square test. Parametric datawere compared by one-way ANOVA or the Kruskal-Wallis test, when necessary. The resultsare expressed as the mean ± standard deviation and a p value <0.05 was considered to be significant.Growth, development, body adiposity and physical fitness characteristics were adequateand proportional to age among the boys studied (p<0.05. It was concluded that anthropometricand physical fitness characteristics of young male elite soccer players improve with and areproportional to age. Children and adolescents greatly benefit from regular physical activity. Thepresent results show that young male soccer players present adequate anthropometric conditionsand physical fitness prior to the initiation of formal training at soccer clubs.
. Lindhard's importance in the history of gymnastics is mainly attributable to the fact that he had a huge influence in the gendering of the behavioural codes of conduct and the formulation of a gender-specific movement programme aimed at the socialisation of boys and girls as well as men and women...... in accordance with the new gender roles of the emerging capitalist society with its strict division of education and labour between the two sexes. Lindhard clearly supported difference-feminism in contrast to 'resemblance-feminism'. These two concepts of femininity clashed in a fierce struggle in the inter...

Fertility preservation options are limited in prepubertal boys with cancer. Worldwide there has been growing interest in testicular tissue cryopreservation as a promising experimental strategy to address future infertility. We measured and compared parent, male cancer survivor and provider willingness to accept the risk of testicular biopsy among prepubertal boys with cancer, and identified reactions to disclosure practices. We conducted a multicenter study that included 153 parents of prepubertal boys with cancer, 77 male survivors of childhood cancer and 30 oncology providers. The threshold technique was used to measure subject relative willingness to accept risk of testicular biopsy under 4 different aspects of care, ie chance of infertility, complications from biopsy, development of technology to use tissue and tissue storage cost. A total of 47 in-depth interviews were conducted to identify reactions to disclosure practices. A total of 52 survivors (67%), 22 providers (73%) and 110 parents (72%) selected to have testicular biopsy (vs no biopsy). Median minimum infertility risk to make biopsy worthwhile varied from 25% to 30% among the 3 respondent groups. Interviews revealed that some providers would not offer biopsy in cases of greater perceived risk than benefit, that parents preferred having information regardless of risk of infertility and that nondisclosure elicited adverse feelings from some parents. Parents, survivors and providers were willing to accept risk of prepubertal testicular biopsy. Parental/survivor desire for information and provider decision not to disclose suggest that barriers to information delivery need to be addressed.

To explore male students' attitudes towards menstruation. Menstruation is a biological event that is often surrounded by secrecy and social stigma that causes anxiety amongst many young girls. A key element of this is the attitudes of young males towards this reproductive health issue. However, the literature around what young males think and feel about menstruation is limited. Qualitative. A sample of 27 male students aged between 10-12 years participated in five focus groups. Data were then subject to a thematic analysis. Five themes emerged from the data analysis that reflected the boys' feelings, experiences and attitudes towards menstruation: 'A silent topic', 'An unimportant issue', 'Errant information about menstruation'. In addition, according to their experience, participants gradually came to see menstruation from the 'menstrual stereotype' viewpoint. In their social life, they made choices that resulted in gradually regulating their behaviour that affected their 'relationships with girls'. Young boys have misguided knowledge about menstruation and this helps to perpetuate the stigma surrounding this element of reproductive health. Boys also express a desire to learn more but are often restricted in this by home and school. School nurses are the best placed professionals to address this issue. Menstrual education with boys should take a greater prominence than it often does in sexual health education in schools. Such inclusion will provide boys with a balanced and accurate knowledge base and therefore help towards reducing the social stigma around menstruation that is often experienced by young girls. © 2011 Blackwell Publishing Ltd.
Full Text Available The Deconstruction of the Cartesian Dichotomy of Black and Whitein William Blake’s The Little Black Boy Abstract This paper discusses English Romantic Poet William Blake’s anti-racial views in his poem The Little Black Boy. In so doing, it focuses upon how Blake attempts to deconstruct the Cartesian dichotomy of Western world view, a dichotomy which has usually been based on “the theory that the universe has been ruled from its origins by two conflicting powers, one good and one evil, both existing as equally ultimate first causes.” In this binary and hierarchal relationship, there are two essential terms in which one term is absolutely regarded as primary or fundamental in its essence, whereas the other term is considered secondary or something that lacks originality and presence. Once this equation is applied to the relationship between black and white people, it will easily be seen in the Western world that white people are always primary or fundamental to black-skinned people, and thus the perception behind this binary and hierarchal relationship seems the root of all the racial problems between black and white. This paper argues that Blake strives to deconstruct radically in The Little Black Boy the basis of this binary and hierarchal relationship which has been carried out for centuries in the Western world to segregate and then control the lives of black people. Finally, the paper maintains that Blake also shows a strong aspiration for creating an egalitarian society free of discrimination and injustices at a time when anti-slavery campaigns hit the top on both sides of Atlantic.

Full Text Available Dermatoglyphics, ridge constellations on the hands and feet, are permanently formed by the second trimester of pregnancy. Consequently, they are considered “fossilized” evidence of a specific prenatal period. A high frequency of dermatoglyphic anomalies, or a high rate of dermatoglyphic asymmetry (discordance, is an indication of developmental instability (prenatal disturbances prior to 24-week gestation. Most dermatoglyphic studies in psychiatry focus on adult schizophrenia. Studies on dermatoglyphic deviances and autism are sparse, include severely disturbed and intellectually retarded patients with autism, and are carried out mainly in non-Western European populations. In this study, finger print patterns, atd-angles, and palmar flexion crease patterns (PFCs are compared between Western European adolescent teenage males, of average intellect, with Autism Spectrum Disorders (ASD; n=46 and typically developing adolescent teenage males (TD; n=49. Boys with ASD had a higher rate of discordance in their finger print patterns than TD boys. Thus, the hypothesized prenatal disturbances that play a role in the etiology of schizophrenia and severe autism might not be specific to these severe psychiatric disorders but might also be involved in the etiology of varying degrees of ASD.

Group treatment programs for pedophiles are often designed for populations of convicted men in closed institutions with limited application to other populations. Treatment is usually focused on reducing the "deviant" sexual arousal and/or acquiring heterosocial skills and eventually establishing the ability to engage in adult heterosexual relationships. A six-week, highly structured program is presented to five men in a non-residential setting. In addition to individual psychotherapy, group counseling is offered. Male pedophiles are trained to talk effectively about common problems surrounding man-boy relationships. Counseling is based on the notion that the emotional, erotic and sexual attraction to boys per se does not need to be legitimized or modified. The attraction, however, can be a source of psychological and social problems that can be handled by using a social support system. Social support for pedophile problems can be obtained from and in interaction with other pedophiles.

Full Text Available A 15-year-old boy was referred due to gynecomastia and short stature. He was overweight and showed the knuckle-dimple sign on the left hand, a short fourth toe on the left foot, and male external genitalia with a small phallus. His levels of estradiol and follicle-stimulating hormone were increased, and his testosterone concentration was normal. Other hormonal tests were within the normal range. Radiographs showed short fourth and fifth metacarpals and fourth metatarsal bones. The karyotype was reported as 46,X,+mar, and the marker chromosome was shown to originate from the Y chromosome, which was identified by fluorescence in situ hybridization. Polymerase chain reaction and direct sequencing were used to clarify the deleted loci of the Y chromosome by making use of Y-specific sequence-tagged sites (STSs. The sex-determining region Y and centromere were verified, and there were microdeletions on the long arm of the Y chromosome. The azoospermia factor (AZF b region was partially deleted, and AZFa and AZFc were completely deleted. Two STS probes of sY143 and the Y chromosome RNA recognition motif in AZFb showed positive signals corresponding to Yq11.223. The karyotype of the patient was interpreted as 46,X,der(Ydel(Y(q11.21q11.222del(Y(q11.23qter. Herein, we report a rare case of a boy presenting with gynecomastia and short stature with 46, X, +mar, which originated from the Y chromosome, which was identified to have Yq microdeletions.

Children with autism vary widely in their language abilities, yet the neural correlates of this language variability remain unclear, especially early in development. Diffusion tensor imaging (DTI) was used to examine diffusivity measures along the length of 18 major fiber tracts in 104 preschool-aged boys with autism spectrum disorder (ASD). The boys were assigned to subgroups according to their level of language development (Low: no/low language, Middle: small vocabulary, High: large vocabulary and grammar), based on their raw scores on the expressive language (EL) and receptive language (RL) sections of the Mullen Scales of Early Learning (MSEL). Results indicate that the subgroups differed in fractional anisotropy (FA), mean diffusivity (MD), and radial diffusivity (RD) along the inferior longitudinal fasciculus (ILF) in both hemispheres. Moreover, FA correlated significantly with Mullen EL and RL raw scores, but not ADOS severity score, along the left and right ILF. Subgroups also differed in MD (but not FA) along the left superior longitudinal fasiculus and left corticospinal tract, but these differences were not correlated with language scores. These findings suggest that white matter microstructure in the left and right ILF varies in relation to lexical development in young males with ASD. The findings also support the use of raw scores on language-relevant standardized tests for assessing early language-brain relationships.

Scientific evidence for a male-typed depression ("male depression") is still limited, but mainly supports this concept with respect to single externalizing symptoms or symptom clusters. In particular, studies on non-clinical populations including males and females are lacking. The present study aims at assessing general well-being, the risk and the symptoms of male depression dependent on biological sex and gender-role orientation on instrumental (masculine) and expressive (feminine) personality traits in an unselected community sample of males and females. Students (518 males, 500 females) of the Ludwig-Maximilians-University of Munich, Germany, were asked to participate in a "stress study" and complete the following self-report questionnaires: the WHO-5 Well-being Index [Bech, P., 1998. Quality of Life in the Psychiatric Patient. Mosby-Wolfe, London], the Gotland Scale for Male Depression [Walinder, J., Rutz, W., 2001. Male depression and suicide. International Clinical Psychopharmacology 16 (suppl 2), 21-24] and the German Extended Personal Attribute Questionnaire [Runge, T.E., Frey, D., Gollwitzer, P.M., et al., 1981. Masculine (instrumental) and feminine (expressive) traits. A comparison between students in the United States and West Germany. Journal of Cross-Cultural Psychology 12, 142-162]. General well-being of the students was significantly lower compared to population norms. Contrary to expectations, female students had a greater risk of male depression than male students (28.9% vs. 22.4%; p<0.05). Overall, prototypic depressive symptoms as well as externalizing symptoms were more pronounced in females. In the subgroup of those at risk for male depression, biological sex and kind of symptoms were unrelated. Principal component analyses revealed a similar symptom structure for males and females. Low scores on masculinity/instrumentality significantly predicted higher risk of male depression, independent of biological sex. The study sample is not

Despite strong genetic influences in autism, the true mode of inheritance remains unknown. Sex differences in autism have been described in both singleton and multiplex families: boys outnumber girls by 3 or 4 to 1, and so a sex-linked mode of transmission must also be considered. The key characteristic of X-linkage is that all sons of affected men are unaffected (no male-to-male transmission). In the present study, which is part of an ongoing linkage project in autism, we describe 77 multiplex autism families, 11 of who are affected cousin or half-sibling families. By using these families, it is possible to trace the path of genetic transmission and observe whether the hypothesis of X-linkage is tenable. Of 11 extended pedigrees from 77 multiplex families, six show male-to-male transmission; in these families, X-linkage can be excluded as the genetic basis for their autism. The data from the other five families are compatible with either an autosomal or an X-linked mode of transmission. The key point to emerge, then, is that autism cannot be exclusively an X-linked disorder; there must be an autosomal mode of transmission at least in some families. Thus we must consider the alternative hypotheses that autism is either entirely autosomal, or it is genetically heterogeneous, involving at least one autosomal locus with gender-specific expression, as well as a possible locus on the X-chromosome. 28 refs., 1 fig.

The biological basis for male contraception was established decades ago, but despite promising breakthroughs and the financial burden men increasingly bear due to better enforcement of child support policies, no viable alternative to the condom has been brought to market. Men who wish to control their fertility must rely on female compliance with contraceptives, barrier methods, vasectomy or abstinence. Over the last 10 years, the pharmaceutical industry has abandoned most of its investment in the field, leaving only nonprofit organisations and public entities pursuing male contraception. Leading explanations are uncertain forecasts of market demand pitted against the need for critical investments to demonstrate the safety of existing candidate products. This paper explores the developments and challenges in male contraception research. We produce preliminary estimates of potential market size for a safe and effective male contraceptive based on available data to estimate the potential market for a novel male method.

Based on the experiences of the Gotland Study that education of general practitioners about depressive illness resulted in a statistically significant reduction in the number of female suicides, leaving the rate of male suicides almost unaffected, we propose the concept of a male depressive syndrome. This syndrome comprises a low stress tolerance, an acting-out behavior, a low impulse control, substance abuse and a hereditary loading of depressive illness, alcoholism and suicide. This notion is supported by data from The Amish study as well as the concept of van Praag of a stress-precipitated, cortisol-induced, serotonin-related and anxiety-driven depressive illness most often seen in males. In order to identify depressed males, the Gotland Male Depression Scale has been developed. Some preliminary data using the scale in a group of alcohol-dependant patients are presented.

Full Text Available Introduction. Nowadays, the use of information and communication technologies (ICT has become an integral part both of every individual’s life and of the society in general. It is no longer possible to deny the impact of virtual environment on socialisation and development of the identity of young people. In this regard, the investigation of young people’s view on virtual social networks, and the possibility of students’ own competitiveness realization through various web services. The aim of the research presented in the article is to study the factors of students’ assessment of virtual social networks as a tool of personal fulfillment. Methodology and research methods. Content analysis and synthesis of scientific publications studies were carried out at a theoretical stage of the research; secondary sampling analysis of sociologic data material sources was conducted. The empirical research stage involved the instrument of questionnaire surveys, statistical data processing and interpretation of the results. Results and scientific novelty. The social survey conducted in 2017 with the participation of 1087 high school students and 1196 college students of the Tyumen Region shown that the more competitive students consider themselves, the more competitive they perceive the people having great popularity on the Internet. At that, compared to girls, young people are more inclined to consider the people having great popularity on the Internet competitive. It is determined that having a popular virtual media account for the young person is less worthwhile than for female respondents. The author explains this fact: male representatives regard it as “social capital” which can contribute to growth of their competitiveness in society as well as to achieve some profit. The author concludes that youth views on competitiveness are not directly related to the activity in virtual social networks. Frequent use by respondents of the Internet and
Full Text Available The present case study investigates the effects of a cognitive training of verbal working memory that was proposed for Davide, a fourteen-year-old boy diagnosed with mild intellectual disability. The program stimulated attention, inhibition, switching, and the ability to engage either in verbal dual tasks or in producing inferences after the content of a short passage had been encoded in episodic memory. Key elements in our program included (1 core training of target cognitive mechanisms; (2 guided practice emphasizing concrete strategies to engage in exercises; and (3 a variable amount of adult support. The study explored whether such a complex program produced near transfer effects on an untrained dual task assessing verbal working memory and whether effects on this and other target cognitive mechanisms (i.e., attention, inhibition and switching were long-lasting and produced far transfer effects on cognitive flexibility. The effects of the intervention program were investigated with a research design consisting of four subsequent phases lasting eight or ten weeks, each preceded and followed by testing. There was a control condition (phase 1 in which the boy received, at home, a stimulation focused on the visuospatial domain. Subsequently, there were three experimental training phases, in which stimulation in the verbal domain was first focused on attention and inhibition (phase 2a, then on switching and simple working memory tasks (phase 2b, then on complex working memory tasks (phase 3. A battery of neuropsychological tests was administered before and after each training phase and seven months after the conclusion of the intervention. The main finding was that Davide changed from being incapable of addressing the dual task request of the listening span test in the initial assessment to performing close to the normal limits of a thirteen-year-old boy in the follow-up assessment with this test, when he was fifteen years old.

There is an increasing prevalence of children/young people with long-term conditions (LTC) in the UK due to improvements in health-care management and delivery. These children are often involved, from an early age, in their own care and management; yet, there are little data to support how or when they develop the necessary skills and knowledge to become competent at this care. This study aimed to understand self-management of haemophilia, from a child's perspective, in the 21st century in the UK where intensive prophylactic therapy is given from early childhood. A qualitative study using grounded theory to evaluate life-experiences of children and young people with haemophilia. Thirty boys aged 4-16 with severe haemophilia treated at a single paediatric haemophilia care centre were interviewed at home or in a focus group. Multimethod qualitative research including age-appropriate research tools (draw and write, photo-elicitation and interviews) to facilitate data collection from children. Boys develop self-management skills over time. They learn from health-care professionals, their parents and other family members with haemophilia. Self-management skills (bleed recognition, self-infusion, self and medicines management, pain and risk management and conceptualizing preventative therapy) are developed through experiential learning and individualized education, and not through formalized expert patient programmes. The boys in this study have benefited from early prophylactic factor replacement therapy. They develop skills in haemophilia and self-management at a relatively young age and are experts in their own haemophilia care. © 2013 John Wiley & Sons Ltd.

The aim of this study was to explore the effect of the Active Teen Leaders Avoiding Screen-time (ATLAS) intervention on psychological well-being in adolescent boys and to examine the potential mediating mechanisms that might explain this effect. ATLAS was evaluated using a cluster randomized controlled trial in 14 secondary schools located in low-income communities (N = 361 adolescent boys, mean age = 12.7 ± .5 years). The 20-week intervention was guided by self-determination theory and involved: professional development for teachers, provision of fitness equipment to schools, enhanced school sport sessions, researcher-led seminars, a smartphone application, and parental strategies for reducing screen time. Assessments were conducted at baseline and immediately post intervention (8 months). Psychological well-being was measured using the Flourishing Scale. Motivational regulations (intrinsic, identified, introjected, controlled, and amotivation) and basic psychological needs (autonomy, competence, and relatedness) in school sport, muscular fitness, resistance training skill competency, and recreational screen time were examined as potential mediating mechanisms of the intervention effect. The intervention effect on well-being was small but statistically significant. Within a multiple mediator model, changes in autonomy needs satisfaction, recreational screen time, and muscular fitness significantly mediated the effect of the intervention on psychological well-being. In addition to the physical health benefits, targeted physical activity programs for adolescent boys may have utility for mental health promotion through the mechanisms of increasing autonomy support and muscular fitness and reducing screen time.

In the transition from early to mid-adolescence, gender differences in pubertal development become significant. Body dissatisfaction is often associated with body mass, low self-esteem and abnormal eating habits. The majority of studies investigating body dissatisfaction and its associations have been conducted on female populations. However, some evidence suggests that males also suffer from these problems and that gender differences might already be observed in adolescence. To examine body dissatisfaction and its relationship with body mass, as well as self-esteem and eating habits, in girls and boys in transition from early to mid-adolescence. School nurses recorded the heights and weights of 659 girls and 711 boys with a mean age of 14.5 years. The Rosenberg Self-Esteem Scale and the Body Dissatisfaction subscale of the Eating Disorder Inventory were used as self-appraisal scales. Eating data were self-reported. The girls were less satisfied with their bodies than boys were with theirs (mean score (SD): 30.6 (SD 12.2) vs. 18.9 (SD 9.5); p eating habits were less satisfied with their bodies than those describing normal eating habits (mean (SD): 33.0 (12.9) vs. 21.2 (10.2); p eating habits revealed a significant relationship with body dissatisfaction in the transitional phase from early to mid-adolescence in girls and boys, but significant gender differences were also found.

A three-phase study tested the hypothesis that the decrease in the high-density lipoprotein cholesterol (HDL-C) level observed in boys at puberty is related to an increase in the plasma testosterone concentration. In phase I, 57 boys aged 10 to 17 years were categorized into four pubertal stages based on clinical parameters and plasma testosterone levels. These four groups showed increasing plasma testosterone values and decreasing HDL-C levels. In phase II, 14 boys with delayed adolescence were treated with testosterone enanthate. Plasma testosterone levels during therapy were in the adult male range. Levels of HDL-C decreased by a mean of 7.4 mg/dL (0.20 mmol/L) and 13.7 mg/dL (0.35 mmol/L), respectively, after the first two doses. In phase III, 13 boys with delayed adolescence demonstrated increasing plasma testosterone levels and decreasing HDL-C levels during spontaneous puberty. Levels of HDL-C and apolipoprotein A-1 were correlated during induced and spontaneous puberty. Testosterone should be considered a significant determinant of plasma HDL-C levels during pubertal development
