    The purpose of this study was to compare morality judgments of American Catholics and the general public about lesbians and gay men adopting and teaching children. The general sample endorsed higher agreement that lesbians and gay men should be allowed to adopt and to teach children compared to the Catholic only sample. Older participants were less accepting than all other age groups, and there was an interaction effect between education and political ideology such that those with less education and with more politically conservative beliefs were generally less accepting of lesbians and gay men adopting and teaching children.

    1999-08-01

    The Mexican American Community Services Agency's (MACSA) male involvement program aims to delay early sexual activities among young boys, educate young males on personal sexual responsibility, prevent the spread of sexually transmitted diseases and unplanned pregnancies, and promote fatherhood responsibility. 40% of the population in the project area, Santa Clara County, belong to ethnic minorities. The program's target population is divided into three age ranges: 10-14, 15-19, and 20-24 year olds. Boys in the 10-14 year old range are accessed through programs at middle schools, community centers and MACSA centers. The 15-19 year age group are reached through the juvenile probation department, its own youth center, community health fairs and service organizations, and local high schools. Young men aged 20-24 years are channeled through adult education classes, incarceration facilities, trade and special training schools, community centers and other MACSA programs. MACSA programs "Be Proud, Be Responsible" and "Independent Thinking Skills" are presented to young men who are prone to gang activity and drug use. Part of the program offered at Elmwood Correctional Facility focuses on issues aside from pregnancy prevention and encourages young men to plan for their future through sessions on earning high school equivalency certification, on anger management, and on substance abuse.

    2015-03-01

    The objective was to use thermal imaging (ThermaCAM SC500) as an effective tool in establishing a thermal map of young participants, with a high diagnostic value for medicine, physiotherapy and sport. A further aim was to establish temperature distributions and ranges on the body surface of the young women and men as standard temperatures for the examined age group, taking into account BMI, body surface area and selected parameters of body fat distribution. The participants included young, healthy and physically active women (n = 100) and men (n = 100). In the women and men, the highest Tmean temperatures were found on the trunk. The warmest were the chest and upper back, then the lower back and abdomen. The lowest Tmean were found in the distal parts of the body, especially on the lower limbs. The results showed that only in the area of the chest was Tmean significantly higher in women than in men. In the areas of the hands (front and back) Tmean were similar for women and men. In the other analyzed body surface areas, Tmean were significantly lower in women. Research showed significant differences in body surface temperature between the women and men. Among the analyzed characteristics, Tmean in the chest, upper back, abdomen, lower back (both in women and men) were mainly correlated with BMI and PBF; the correlations were negative. Difficulties in interpreting changes in temperature in selected body areas in people with various conditions can be associated with the lack of studies on large and representative populations of healthy individuals with normal weight/height parameters. Therefore, it seems that this presented research is a significant practical and cognitive contribution to knowledge on thermoregulation, and may therefore be used as a reference for other studies using thermal imaging in the evaluation of changes in body surface temperatures.

    Full Text Available Abstract Backround Appearance concerns are of increasing importance in young men's lives. We investigated whether muscle dissatisfaction is associated with psychological symptoms, dietary supplement or anabolic steroid use, or physical activity in young men. Methods As a part of a questionnaire assessment of health-related behaviors in the population-based FinnTwin16 study, we assessed factors associated with muscle dissatisfaction in 1245 men aged 22–27 using logistic regression models. Results Of men, 30% experienced high muscle dissatisfaction, while 12% used supplements/steroids. Of highly muscle-dissatisfied men, 21.5% used supplements/steroids. Mean body mass index, waist circumference, or leisure aerobic activity index did not differ between individuals with high/low muscle dissatisfaction. Muscle dissatisfaction was significantly associated with a psychological and psychosomatic problems, alcohol and drug use, lower height satisfaction, sedentary lifestyle, poor subjective physical fitness, and lower life satisfaction. Conclusion Muscle dissatisfaction and supplement/steroid use are relatively common, and are associated with psychological distress and markers of sedentary lifestyle.

    2016-08-01

    By adulthood, people judge trustworthiness from appearances rapidly and reliably. However, we know little about these judgments in children. This novel study investigates the developmental trajectory of explicit trust judgments from faces, and the contribution made by emotion cues across age groups. Five-, 7-, 10-year-olds, and adults rated the trustworthiness of trustworthy and untrustworthy faces with neutral expressions. The same participants also rated faces displaying overt happy and angry expressions, allowing us to investigate whether emotion cues modulate trustworthiness judgments similarly in children and adults. Results revealed that the ability to evaluate the trustworthiness of faces emerges in childhood, but may not be adult like until 10 years of age. Moreover, we show that emotion cues modulate trust judgments in young children, as well as adults. Anger cues diminished the appearance of trustworthiness for participants from 5 years of age and happy cues increased it, although this effect did not consistently emerge until later in childhood, that is, 10 years of age. These associations also extended to more subtle emotion cues present in neutral faces. Our results indicate that young children are sensitive to facial trustworthiness, and suggest that similar expression cues modulate these judgments in children and adults. © 2015 The British Psychological Society.

  17. Teenage pregnancy prevention: the role of young men.

    2017-08-01

    Although teenage pregnancy is declining in many parts of the world, it remains associated with considerable social, health, and economic outcomes. Pregnancy prevention efforts focus primarily on young women, with minimal attention to young men. This review highlights recent literature pertaining to the role of young men in pregnancy prevention. Young men have varying views on contraception as well as which partner(s) should be responsible for its use. Limited contraception knowledge reduces young men's sexual health communication as well as their contraception use. Healthcare providers play a major role as one of the main sources of sexual health information for young men, but there are gaps in young men's sexual health care so new guidelines have emerged. Recent literature highlights young men's range of views on contraception as well as their low sexual health knowledge and sexual health communication. To address teenage pregnancy and improve young men's overall wellness, healthcare providers should routinely address sexual health. Healthcare providers may use our newly proposed acronym, HIS BESTT, (Hello. Initiate. Sexual health assessment. Both condoms and female dependent methods. Examine genitals. STI screening. Talking to partner(s). Talking to parent(s) or guardians), to incorporate current clinical recommendations.

  20. Attractiveness judgments and discrimination of mommies and grandmas: perceptual tuning for young adult faces.

    Adults are more accurate in detecting deviations from normality in young adult faces than in older adult faces despite exhibiting comparable accuracy in discriminating both face ages. This deficit in judging the normality of older faces may be due to reliance on a face space optimized for the dimensions of young adult faces, perhaps because of early and continuous experience with young adult faces. Here we examined the emergence of this young adult face bias by testing 3- and 7-year-old children on a child-friendly version of the task used to test adults. In an attractiveness judgment task, children viewed young and older adult face pairs; each pair consisted of an unaltered face and a distorted face of the same identity. Children pointed to the prettiest face, which served as a measure of their sensitivity to the dimensions on which faces vary relative to a norm. To examine whether biases in the attractiveness task were specific to deficits in referencing a norm or extended to impaired discrimination, we tested children on a simultaneous match-to-sample task with the same stimuli. Both age groups were more accurate in judging the attractiveness of young faces relative to older faces; however, unlike adults, the young adult face bias extended to the match-to-sample task. These results suggest that by 3 years of age, children's perceptual system is more finely tuned for young adult faces than for older adult faces, which may support past findings of superior recognition for young adult faces.

    2016-03-01

    This exploratory descriptive study examined perceived vulnerabilities to human papillomavirus (HPV) and the correlation to factors influencing vaccine beliefs and vaccine decision making in young Hispanic males attending a large public urban university. Only 24% of participants believed that the HPV vaccine could prevent future problems, and 53% said they would not be vaccinated. The best predictors of HPV vaccination in young Hispanic men were agreement with doctor recommendations and belief in the vaccine's efficacy. Machismo cultural norms influence young Hispanic men's HPV-related decision making, their perceptions of the vaccine, and how they attitudinally act on what little HPV information they have access to. This study provides culturally relevant information for the development of targeted health education strategies aimed at increasing HPV vaccination in young Hispanic men. © The Author(s) 2014.

  10. Straining: Young Men Working through Waithood in Freetown, Sierra Leone

    Directory of Open Access Journals (Sweden)

    Brandon Finn

    2015-01-01

    Full Text Available Young men in precarious situations of persistent un(deremployment in post-civil war Freetown, Sierra Leone are depicted in popular and policy debate as “stuck” economically or “dangerous” and prone to violence. In the present paper, by contrast, we draw on young men’s explanations of their work and livelihood struggles as “straining.” We explore the logic of straining, its innovations and demands, and its geography across the city, especially where acts of straining interface with the prohibition and criminalisation of informal trading. We argue that straining innovates and endures because of (not despite young men’s marginalisation and limited autonomy and power. In this context, young men build forms of provisional agency and enact dynamic forms of waithood, in their strategies to earn a living to try to support their families and to negotiate a transition from youth to manhood. Drawing on this research, we argue for a more complex understanding of young men at work in Freetown, in particular, and of the “youth bulge,” in general, in African cities.

    We investigated a healthy population of men from different regions of Turkey for the presence of congenital red-green color blindness. Using Ishihara pseudoisochromatic plates, 941 healthy men from the Turkish army were tested for congenital red-green color blindness. The prevalence of red-green color blindness was 7.33 +/- 0.98% (5.10% protans and 2.23% deutans). These ratios were higher than other reported samples from Mediterranean Europe. Higher percentages of color blindness were found in regions with a lower education level and more consanguineous marriages.

    Full Text Available We have conducted an empirical study of the dynamics of the level of moral judgments in the military. Two groups of Missile Defense Force soldiers present the sample: preparing for demobilization (n=30 and new recruits (n=25. As the methods we used specially developed semi-structured interview modeling the situation of moral choice, and the questionnaire in order to assess the socio-psychological characteristics of the military and their attitude to service. The young soldiers have a positive trend in the development of moral judgments and a greater differentiation in the estimates. It is shown that the old-timers in comparison with newcomers have intensive development of group-oriented and prosocial moral reasoning. It presumably connected with successful adaptation to military service, following the manual, the ability to cope with aggressive impulses, flexibility and value assessments in decision-making. It is noted that educational work with young recruits should include measures to increase group cohesion in the army.

    Full Text Available Abstract Men who have sex with men (MSM especially those who are HIV positive are at risk for HPV-associated anal cancer. We systematically reviewed studies with data on the prevalence of vaccine preventable anal HPV among men who have sex with men aged 25 or younger and identified 6 studies. None of these studies were specifically designed to determine the prevalence of HPV in this population. Available data, albeit limited, suggest many young MSM may not already be HPV infected. Further studies using representative sampling focused on teenage MSM are required to confirm this.

    2009-10-01

    Recruiting a scientifically sound cohort of young men who have sex with men (YMSM) is an enduring research challenge. The few cohort studies that have been conducted to date on YMSM have relied on non-probability sampling methods to construct their cohorts. While these studies have provided valuable information about HIV risk behaviors among YMSM, their generalizability to broader YMSM populations is limited.In this paper the authors describe a venue-based sampling methodology used to recruit a large and diverse cohort of YMSM from public venues in Los Angeles County. Venue-based sampling is a multi-stage, probability sampling design that uses standard outreach techniques and standard survey methods to systematically enumerate, sample, and survey hard-to-reach populations. The study design allowed the authors to estimate individual, familial and interpersonal psychosocial factors associated with HIV risk and health seeking behaviors for a cohort of YMSM with known properties. Study participants completed an extensive baseline survey and over a two year period will complete four follow-up surveys at six-month intervals. The baseline survey was administered in both English and Spanish.

  15. Young men in RJ-settings: An offstage performance

    DEFF Research Database (Denmark)

    Empirical, qualitative studies in Danish and Norwegian RJ-sessions show, that young men (offenders and victims) are characterised by passive acquiescence, by not expressing opinions, by getting out of their ‘turn to talk’ as quickly as possible and by silence. The way this type of ‘non-acting’ has...... been understood is that youth are subject to adult conceptions and interpretations of the mediation situation, and that the youth have not yet developed empathy and moral reasoning. In other words the young men are seen as taking a kind of ‘underdog’ position in the RJ-settings. The interpretation......-reflection and articulation of personal feelings, which does not correspond to traditional ideals of masculinity as strength, authority and control. From this point of view the young men are not trying to fit in, but actually the opposite: to make a revolt by not entering the “scene” - doing an “offstage” performance...

    Smile is a crucial factor in creating a good first impression. However conditions like dental fluorosis hamper the esthetics of teeth. This study was conducted to find out whether young adults attribute socially relevant characteristics to people with dental fluorosis. A total of 150 young adults were presented with images of individuals with different severity levels of dental fluorosis along with images of normal tooth appearance on a computer screen. They had to attribute various socially relevant characteristics to these images. Images were digitally manipulated to simulate dental fluorosis. Images were displayed on a computer screen and Visual Basic Software was used to record the participants' responses as well as the time taken to respond. The time taken to respond or response latency indicates the response strength. A chi-square test was used to test the association between the dental appearances and the socially relevant characteristics. A Mann--Whitney test was used to compare the time taken to respond. As the severity of fluorosis increases, participants attribute less and less of positive characteristics. Attribution of negative characteristics also increases with the severity of dental fluorosis. For images with moderate and severe fluorosis, respondents took more time to accept positive characteristics and less time to reject positive characteristic. This means that the participants felt strongly when rejecting positive characteristics in these images. Social judgments are made by young adults when viewing digitally manipulated images of different levels of fluorosis.

    In the United States, anabolic sex steroids are administered to cattle for growth promotion. There is concern regarding the reproductive consequences of this practice in men who eat beef. We investigated whether meat consumption was associated with semen quality parameters and reproductive hormone levels in young men. Semen samples were obtained from 189 men aged 18-22 years. Diet was assessed with a previously validated food frequency questionnaire. We used linear regression to analyze the cross-sectional associations of meat intake with semen quality parameters and reproductive hormones while adjusting for potential confounders. There was an inverse relation between processed red meat intake and total sperm count. The adjusted relative differences in total sperm counts for men in increasing quartiles of processed meat intake were 0 (ref), -3 (95% confidence interval = -67 to 37), -14 (-82 to 28), and -78 (-202 to -5) million (test for trend, P = 0.01). This association was strongest among men with abstinence time less than 2 days and was driven by a strong inverse relation between processed red meat intake and ejaculate volume (test for trend, P = 0.003). In our population of young men, processed meat intake was associated with lower total sperm count. We cannot distinguish whether this association is because of residual confounding by abstinence time or represents a true biological effect.

    Full Text Available Stature concerns are a prominent source of body dissatisfaction for Chinese teenagers and young adults, yet little is known about the psychological factors that account for it. Therefore, this study examined social cultural model and objectification theory as explanations for stature concerns in a sample of undergraduate men and women from a university in Henan, China. Given height is a salient physical attribute for Chinese adolescents and young adults, we extended past studies on objectification theory by adding separate measures for stature surveillance. Participants (231 men, 473 women completed a questionnaire assaying measures of sociocultural model features (appearance pressure from mass media and close interpersonal networks, appearance social comparisons, objectified body consciousness (body surveillance, body shame, stature surveillance, and stature concerns. In multiple regression models for each gender, appearance pressure from the mass media and stature surveillance were robust predictors of stature concerns for both genders, independent of reported height. Body surveillance predicted stature concerns for women but not men. These findings contribute to the broader field of multicultural body image research and may help to account for specific culturally salient appearance concerns within samples of young Chinese women and men.

  8. Playing spades: The rich resources of African American young men

    Schademan, Alfred R.

    Research has shown that African American young men as a demographic group occupy the lowest levels of academic performance in both science and mathematics. In spite of this educational problem, little research has been conducted on the knowledge related to these disciplines that these young men learn and develop through everyday cultural practices. Such knowledge is needed in order to: (1) combat the deficit views that many teachers currently hold of African American young men, and (2) inform teachers interested in implementing pedagogies in their classrooms that draw upon the knowledge of African American young men. To add to our knowledge in this field, this study examines the resources that African American young men learn, use, and develop through a card game called Spades. Specifically, the study identifies and analyzes the models and model-based reasoning that the players use in order to win games. The study focuses upon modeling as it is central to both science and mathematics. To imbed player models and reasoning in context, the study employs a syncretic theoretical framework that examines how Spades has changed over time and how it is currently played in a high school setting. The qualitative study uses ethnographic methods combined with play-by-play analyses to reconstruct games and examine player strategies and reasoning that guide their decisions. The study found that the players operate from a number of different models while playing the game. Specifically, the players consider multiple variables and factors, as well as their mathematical relationships, to predict future occurrences and then play cards accordingly. Further, the players use a number of resources to win games including changing the game to maintain a competitive edge, counting cards, selectively memorizing cards played, assessing risk, bluffing, reading partners as well as opponents, reneging, estimating probabilities, and predicting outcomes. The player models and resources bear

    Empirical, qualitative studies in Danish and Norwegian RJ-sessions show, that young men (offenders and victims) are characterised by passive acquiescence, by not expressing opinions, by getting out of their ‘turn to talk’ as quickly as possible and by silence. The way this type of ‘non-acting’ has...... been understood is that youth are subject to adult conceptions and interpretations of the mediation situation, and that the youth have not yet developed empathy and moral reasoning. In other words the young men are seen as taking a kind of ‘underdog’ position in the RJ-settings. The interpretation...... of the “non-attitude” is changing, when applying Goffman’s notion of people performing a preferred identity, rather than an inherent or fixed self. That means that the words and actions of the participants in the mediation sessions are largely considered to be embedded in the context. In combination...

    We surveyed young men on their experiences of police encounters and subsequent mental health. Between September 2012 and March 2013, we conducted a population-based telephone survey of 1261 young men aged 18 to 26 years in New York City. Respondents reported how many times they were approached by New York Police Department officers, what these encounters entailed, any trauma they attributed to the stops, and their overall anxiety. We analyzed data using cross-sectional regressions. Participants who reported more police contact also reported more trauma and anxiety symptoms, associations tied to how many stops they reported, the intrusiveness of the encounters, and their perceptions of police fairness. The intensity of respondent experiences and their associated health risks raise serious concerns, suggesting a need to reevaluate officer interactions with the public. Less invasive tactics are needed for suspects who may display mental health symptoms and to reduce any psychological harms to individuals stopped.

    In general, focal nodular hyperplasia is a hepatic lesion that most frequently affects the healthy women of reproductive age. Focal nodular hyperplasia lesions have a benign natural course; the majority of the cases remain asymptomatic and complications are rare. Spontaneous hemorrhage of focal nodular hyperplasia is a rare disease, and the hemorrhage in young men is even more uncommon. We report a rare case of spontaneous hemorrhage of focal nodular hyperplasia in a 19-year-old man.

    Abnormal sperm DNA integrity is an important risk factor for male infertility. The aim of this work was to examine sperm DNA fragmentation in a cohort of young male volunteers (n=111; age 21.0+/-0.2 years) from the general population and establish the association between the level of sperm DNA fragmentation and sperm functional parameters. Sperm DNA fragmentation index (DFI) was determined by SCSA (sperm chromatin structure assay) using flow cytometry. Standard semen parameters (concentration, motility, and morphology) were evaluated according to the WHO guidelines (2010). and conclusions. In the study cohort, 79.0%, 12.4% and 8.6% of men had normal (DFIfragmentation, respectively. Men with impaired spermatogenesis had greater IDF values (14.53+/-1.43%) than men with normal semen parameters (8.88+/-0.77%, pfragmentation using SCSA technique can be employed in epidemiological studies of male fertility.

    This study was conducted to investigate the prevalence of premature ejaculation (PE) in young Turkish men and to evaluate PE in a population having good physical and mental health. A total of 1230 healthy university graduates aged between 24 and 30 attending the police academy having no physical or mental problems were included in the study. To identify the presence of PE, the participants were asked to complete the premature ejaculation diagnostic tool (PEDT). The mean ages in the PE and non-PE group were 27.3 and 26.7 respectively. There was no statistically significant difference between the two groups concerning age, body mass index (BMI), smoking status and alcohol consumption (P > 0.05). The PE prevalence was found to be 9.2%. The mean PEDT score was calculated as 6.3. Of the participants, 92 scored 11 and higher (9.2%), 66 scored 9 and 10 (6.6%), and the remaining 842 obtained a score equal to or lower than 8 (84.2%). The lower prevalence of PE in young Turkish men compared to the results of studies in the literature can be attributed to the physical and mental well-being of the participants. This study showed that the prevalence of PE in young men with good physical and mental health is lower than that found in the literature.

  17. Science and scepticism: Drug information, young men and counterpublic health.

    It is perhaps no surprise that young people can be sceptical of the drug-related information they receive in school-based health education, health promotion and the media. Significant societal anxiety surrounds young people's drug consumption, so it is tempting to approach this scepticism as a problem to be solved. In this article, we look closely at a group of young Australian men (n = 25), all of whom hold deeply sceptical views about the drug information they received in schools, social marketing campaigns and public speech generally. We do not approach their scepticism as a problem to be solved in itself, however. Instead, we analyse its origins and how it relates to the way knowledge is constructed in drug education, health promotion and media accounts of drug use. To conceptualise this scepticism, we draw on Irwin and Michael's analysis of the changing relationship between science and society, Warner's theorisation of publics and counterpublics, and Race's related notion of 'counterpublic health'. The article organises the data into three key themes: scepticism about the accuracy of the claims made about drug risks and dangers, scepticism about representations of drug users, and scepticism about the motivations behind the health messages and drug policy in general. We then draw these different aspects of scepticism together to argue that the young men can be seen to constitute a health 'counterpublic', and we consider the implications of this approach, arguing for what has been described as a more diplomatic engagement between science and publics.

    Objectives Male sex, young age, and frequent gambling are considered as risk factors for gambling disorder (GD) and stress might be one of the triggers of gambling behavior among problem gamblers. Conversely, well-developed coping with stress might counteract gambling problems. The Proactive Coping Theory provides a promising approach for the further development of preventive and treatment measures. The objective of the study was to investigate different facets of proactive coping (PC) in young male gamblers. Methods Young men from Bavaria were recruited via the Munich citizens' registry (n = 2,588) and Facebook invitations (n = 105). In total, 173 out of 398 individuals were positively screened for frequent gambling and/or signs of related problems and completed the baseline questionnaire of the Munich Leisure-time Study. Factors investigated include gambling problems, PC, impulsiveness, social support, and psychological distress. Results Gambling problems were associated with lower levels of preventive coping as well as of adaptive reaction delay. The associations were also significant when controlled for impulsiveness and general psychological distress. Preventive coping moderated the association between social support and gambling problems. Discussion and conclusions Young men with gambling problems less frequently prevent the occurrence of stressors and more often react hasty when these occur. While the investigated group reported good social support, this factor was negatively associated with GD only among individuals with good preventive coping. Preventive coping poses a useful construct for selective prevention and treatment as it can be modified in professional interventions.

    Parallel bodies of research have described the diverse and complex ways that men understand and construct their masculine identities (often termed "masculinities") and, separately, how adherence to traditional notions of masculinity places men at risk for negative sexual and health outcomes. The goal of this analysis was to bring together these two streams of inquiry. Using data from a national, online sample of 555 heterosexually active young men, we employed latent class analysis (LCA) to detect patterns of masculine identities based on men's endorsement of behavioral and attitudinal indicators of "dominant" masculinity, including sexual attitudes and behaviors. LCA identified four conceptually distinct masculine identity profiles. Two groups, termed the Normative and Normative/Male Activities groups, respectively, constituted 88 % of the sample and were characterized by low levels of adherence to attitudes, sexual scripts, and behaviors consistent with "dominant" masculinity, but differed in their levels of engagement in male-oriented activities (e.g., sports teams). Only eight percent of the sample comprised a masculinity profile consistent with "traditional" ideas about masculinity; this group was labeled Misogynistic because of high levels of sexual assault and violence toward female partners. The remaining four percent constituted a Sex-Focused group, characterized by high numbers of sexual partners, but relatively low endorsement of other indicators of traditional masculinity. Follow-up analyses showed a small number of differences across groups on sexual and substance use health indicators. Findings have implications for sexual and behavioral health interventions and suggest that very few young men embody or endorse rigidly traditional forms of masculinity.

  20. The Role of Facial and Body Hair Distribution in Women's Judgments of Men's Sexual Attractiveness.

    Dixson, Barnaby J W; Rantala, Markus J

    2016-05-01

    Facial and body hair are some of the most visually conspicuous and sexually dimorphic of all men's secondary sexual traits. Both are androgen dependent, requiring the conversion of testosterone into dihydrotestosterone via the enzyme 5α reductase 2 for their expression. While previous studies on the attractiveness of facial and body hair are equivocal, none have accounted as to how natural variation in their distribution may influence male sexual attractiveness. In the present study, we quantified men's facial and body hair distribution as either very light, light, medium, or heavy using natural photographs. We also tested whether women's fertility influenced their preferences for beards and body hair by comparing preferences among heterosexual women grouped according their fertility (high fertility, low fertility, and contraceptive use). Results showed that men with more evenly and continuously distributed facial hair from the lower jaw connecting to the mustache and covering the cheeks were judged as more sexually attractive than individuals with more patchy facial hair. Men with body hair were less attractive than when clean shaven, with the exception of images depicting some hair around the areolae, pectoral region, and the sternum that were significantly more attractive than clean-shaven bodies. However, there was no effect of fertility on women's preferences for men's beard or body hair distribution. These results suggest that the distribution of facial and body hair influences male attractiveness to women, possibly as an indication of masculine development and the synthesis of testosterone into dihydrotestosterone via 5α reductase.

    Abstract Purpose: Limited data are available on anal squamous intraepithelial lesions (ASILs) and anal human papillomavirus (HPV) infection in young, Black populations. The purpose of this study was to examine the prevalence of and relationships between ASILs and high-risk HPV infection in a young (sex with men (MSM) population. Methods: Results of anal cytology and HPV DNA were gathered for 83 individuals. Results: Forty-two percent of individuals (35) had atypical squamous cells of undetermined significance and 33% (27) had low-grade squamous intraepithelial lesion by cytology. Only 9% tested positive for both high-risk HPV subtypes 16 and 18. Conclusion: Low rates of infection with both HPV types 16 and 18 may provide further evidence that we should continue to vaccinate young, Black MSM against HPV. PMID:27673362

    Health, facial and vocal attributes and body height of men may affect a diverse range of social outcomes such as attractiveness to potential mates and competition for resources. Despite evidence that each parameter plays a role in mate choice, the relative role of each and inter-relationships between them, is still poorly understood. In this study, we tested relationships both between these parameters and with testosterone and immune function. We report positive relationships between testosterone with facial masculinity and attractiveness, and we found that facial masculinity predicted facial attractiveness and antibody response to a vaccine. Moreover, the relationship between antibody response to a hepatitis B vaccine and body height was found to be non-linear, with a positive relationship up to a height of 188 cm, but an inverse relationship in taller men. We found that vocal attractiveness was dependent upon vocal masculinity. The relationship between vocal attractiveness and body height was also non-linear, with a positive relationship of up to 178 cm, which then decreased in taller men. We did not find a significant relationship between body height and the fundamental frequency of vowel sounds provided by young men, while body height negatively correlated with the frequency of second formant. However, formant frequency was not associated with the strength of immune response. Our results demonstrate the potential of vaccination research to reveal costly traits that govern evolution of mate choice in humans and the importance of trade-offs among these traits.

  5. Judging the difference between attractiveness and health: does exposure to model images influence the judgments made by men and women?

    Full Text Available Recent research has shown facial adiposity (apparent weight in the face to be a significant predictor of both attractiveness and health, thus making it an important determinant of mate selection. Studies looking at the relationship between attractiveness and health have shown that individuals differentiate between the two by preferring a lower weight for attractiveness than for health in female faces. However, these studies have either been correlational studies, or have investigated weight perceived from only the face. These differences have been discussed with regard to sociocultural factors such as pressure from parents, peers and also media, which has been seen to have the highest influence. While exposure to media images has been shown to influence women's own-body image, no study has yet directly tested the influence of these factors on people's preferred weight in other women's bodies. Here we examine how a short exposure to images of models influences men's and women's judgments of the most healthy looking and attractive BMI in Malaysian Chinese women's bodies by comparing differences in preferences (for attractiveness and health between groups exposed to images of models of varying attractiveness and body weight. Results indicated that participants preferred a lower weight for attractiveness than for health. Further, women's but not men's preferred BMI for attractiveness, but not health, was influenced by the type of media images to which they were exposed, suggesting that short term exposure to model images affect women's perceptions of attractiveness but not health.

    Blake, K

    1995-01-01

    This article describes the results of a study undertaken to identify perceptions of possible social isolation among individuals who become quadriplegic as young adults. Two focus group sessions were held with 4 male participants in each group. All the young men were between the ages of 19 years and 35 years, and all had been disabled for more than 3 years. The results showed that the participants felt challenged by the environment and their resources but did not experience the feelings associated with social isolation as defined by Goffman (1963). The participants, however, identified important socially isolating stressors based on the human needs described by Maslow (1970) as existing in a hierarchy. The results of the study suggest that people with disabilities need interpersonal techniques that enable them to feel a sense of security and control of their time; rehabilitation nurses are ideally suited to assist clients in developing such techniques.

Using life-history interview data with 30 HIV-positive and HIV-negative young men aged 15-24 years, this analysis offers an in-depth perspective on young men's transition through adolescence, the desire for fatherhood and experience of sexual partnerships in rural Uganda. Young men consistently reported the desire for fatherhood as a cornerstone of masculinity and transition to adulthood. Ideally young men wanted children within socially sanctioned unions. Yet, most young men were unable to realise their marital intentions. Gendered expectations to be economic providers combined with structural constraints, such as limited access to educational and income-generating opportunities, led some young men to engage in a variety of HIV-risk behaviours. Multiple partnerships and limited condom use were at times an attempt by some young men to attain some part of their aspirations related to fatherhood and marriage. Our findings suggest that young men possess relationship and parenthood aspirations that - in an environment of economic scarcity - may influence HIV-related risk.

    Approximately 5% of all military recruits incur stress fracture injuries during intense physical training, predominately in the lower extremity. We compared young men and women with stress fracture injury (subjects) to a matched group of uninjured volunteers (controls) during a summer training program at the United States Naval Academy to identify possible risk factors for stress fracture injury. The subject group was composed of 13 female and 18 male plebes with training-induced stress fracture injury verified by plain radiographs and/or nuclear bone scan. The control group was composed of 13 female and 18 male plebes who remained without injury during plebe summer training but who were matched with the 31 injured plebes for the Initial Strength Test (1-mi run time, means: women, 7.9 min; men, 6.4 min) and body mass index (means: women, 23.4; men, 23.8). We found that the subjects lost significant body weight (mean, 2.63 +/- 0.54 kg) between Day 1 and the date of their diagnosis of a stress fracture (mean, Day 35) and that they continued to lose weight until the date of their DEXA scan (mean, Day 49). Among female plebes, there was no evidence of the female athlete triad (eating disorders, menstrual dysfunction, or low bone density). Thigh girth was significantly smaller in female subjects than in female controls and trended to be lower in male subjects than in male controls. Total body bone mineral content was significantly lower in the male subjects than in male controls. Bone mineral density of the distal tibia and femoral neck were not significantly different between the groups. DEXA-derived structural geometric properties were not different between subjects and controls. Because, on average, tibias were significantly longer in male subjects than in male controls, the mean bone strength index in male subjects was significantly lower than that of male controls. We conclude that significant, acute weight loss combined with regular daily physical training among

    This study aims to explore young men's understanding of intimate partner violence (IPV) in Ecuador, examining similarities and differences between how ordinary and activist young men conceptualize IPV against women. We conducted individual interviews and focus group discussions (FGDs) with 35 young men--five FGDs and five interviews with ordinary young men, and 11 interviews with activists--and analysed the data generated using qualitative content analysis. Among the ordinary young men the theme 'too much gender equality leads to IPV' emerged, while among the activists the theme 'gender inequality is the root of IPV'. Although both groups in our study rejected IPV, their positions differed, and we claim that this is relevant. While activists considered IPV as rooted in gender inequality, ordinary young men understood it as a response to the conflicts generated by increasing gender equality and women's attempts to gain autonomy.

    In order to elucidate cultural correlates of utilization of primary health services by young adult men, we investigated religion in which one was raised and service utilization. Using data from a national survey we tested the hypothesis that religion raised predicts access to and utilization of a regular medical care provider, examinations, HIV and other STD testing and counseling at ages 18-44 years in men born between 1958 and 1984. We also hypothesized that religion raised would be more predictive of utilization for Hispanic Americans and non-Hispanic Black Americans than for non-Hispanic White Americans. The study included a national sample of 4276 men aged 18-44 years. Descriptive and multivariate statistics were used to assess the hypotheses using data on religion raised and responses to 14 items assessing health care access and utilization. Compared to those raised in no religion, those raised mainline Protestant were more likely (p Religion raised was not associated with testicular exams, STD counseling or HIV testing. In multivariate analyses controlling for confounders, significant associations of religion raised with insurance coverage, a physician as usual source of care and physical examination remained which varied by race/ethnicity. In conclusion, although religion is a core aspect of culture that deserves further study as a possible determinant of health care utilization, we were not able to document any consistent pattern of significant association even in a population with high rates of religious participation.

    Aim: To determine the effect of sildenafil citrate on the nocturnal penile erections (I.e. Time to onset, the duration of erection, and the interval between first and second erections) of healthy young men. Methods: Twenty-two potent men, 23-29 years old, were recruited for the study. All subjects completed three sessions over consecutive nights using the RigiScan monitoring device (Dacomed, Minneapolis, USA). After a first night of adaptation, night 2 records were their baseline values, and on night 3 they received 100 mg of sildenafil citrate. Statistical comparisons were done between the second and third night data. Results: The mean time to onset of the first erection with sildenafil citrate was (34 ± 18) min, whereas it was (74 ± 24) min (P < 0.001) without sildenafil citrate. The number of erections observed during the first 5 h after sildenafil citrate medication was 3.6 ± 0.5 in contrast to 2.4 ± 0.5 with no medication (P = 0.001). The interval between first and second erections was shorter with sildenafil citrate: (52 ± 26) min vs.(85 ± 34) min (P = 0.01). The duration of the last erection was statistically significantly longer with the sildenafil citrate: (64 ± 33) min vs. (42 ± 28) min (P < 0.01). Conclusion: Healthy young men achieved erection within 34 min after sildenafil citrate administration, which is shorter than the 1 h interval proposed by the manufacturer. The interval between the first and second erections was shorter and the duration of the last nocturnal erection was longer.

    Men who have sex with men (MSM) represent 64.0% of people living with HIV (PLWH) over the age of 13 years. Young men who have sex with men (YMSM) are particularly affected by HIV/AIDS; the rate of HIV infection for YMSM between the ages of 13 and 24 represents 72.0% of new infections among youth. To understand the current state of the science meant to prevent HIV for YMSM, we reviewed studies of HIV behavioral prevention interventions for YMSM. Five literature databases were searched, from their inception through October 2015, using key words associated with HIV prevention intervention evaluation studies for YMSM. The review criteria included behavioral HIV/AIDS prevention interventions, articles published in English-language peer-reviewed journals, YMSM between 13 and 24 years of age, and longitudinal repeated measures design. A total of 15 YMSM behavioral HIV prevention intervention studies were identified that met inclusion criteria and reported statistically significant findings. Common outcomes included unprotected sexual intercourse, HIV/AIDS risk behavior, condom use, HIV testing, safer sex attitude, and HIV prevention communication. Participant age, representation of Black/African American YMSM, application of theoretical and model underpinnings, congruence of assessment measures used, follow-up assessment times, and application of process evaluation were inconsistent across studies. To advance HIV prevention intervention research for YMSM, future studies should be theory-based, identify common constructs, utilize standard measures, include process evaluation, and evaluate sustained change over standard periods of time. HIV prevention interventions should incorporate the needs of the diverse, well-educated, web-connected millennial generation and differentiate between adolescent YMSM (13 to 18 years of age) and young adulthood YMSM (19 to 24 years of age). Because Black/African American YMSM represent more than 50% of new HIV infections, future HIV

    Young men who have sex with men (MSM) represent an increasing number of new HIV infections in many communities. Many individuals still hold beliefs that may lead to discrimination against HIV-positive individuals. HIV stigma is associated with negative health and psychosocial outcomes and may lead to greater challenges for this marginalized population. This study describes stigma experienced by HIV-positive young MSM, explores its relationship to psychosocial measures, and tests the hypothesis that stigma scores will be higher in those diagnosed less than 1 year ago versus more than 1 year. From August 2004 to September 2005 young MSM completed a questionnaire including demographic information and psychosocial measures. Descriptive and bivariate analyses of association were used to interpret data from the total stigma scale and four subscales: personalized stigma (PS), public attitudes (PA), negative self-image (NSI), and disclosure concerns (DC). Index scores were calculated by standardizing each subscale for direct comparisons. The 42 participants were: mean 21.3 years; 45% black, 24% Hispanic, 26% white; 14% transgender; and 50% diagnosed HIV-positive less than 1 year. Participants reported HIV-related stigma across all domains with mean index subscale scores: PS 0.57, PA 0.61, NSI 0.63, DC 0.75 indicating that disclosure concerns were prevalent in comparison to other forms of HIV-related stigma. Stigma scores correlated with depression, social support, self-esteem, and romantic loneliness. Stigma scores did not differ for those diagnosed less than 1 year ago versus more than 1 year ago. Providers should address HIV-related stigma concerns, particularly disclosure, throughout the trajectory of the illness when caring for HIV-positive young MSM as a factor affecting health outcomes and psychosocial functioning.

    Young African-American (AA) men who have sex with men (YAAMSM) have experienced the greatest proportional increase in new HIV cases compared with other groups. Bridging sexual partnerships between YAAMSM and older aged cohorts with higher rates of primary HIV infection has emerged as an important independent risk factor for the development of HIV. We explored reasons young AAMSM cite for being attracted to and seeking an older partner and the interpersonal needs met within older sexual partnerships. Seventeen in-depth semistructured qualitative interviews were conducted in YAAMSM residing in a midsized urban city with high HIV prevalence. Two coders independently evaluated transcribed data to identify/collapse codes that emerged. We analyzed data using categorical and contextualizing analytic methods. Two themes emerged from the text for seeking an older sexual partner: the emotional maturity the older partner represented and the ability of the older partner to expose the younger partner to more life experiences. In addition, two themes emerged around attraction: support and physical attractiveness of the older partner. Few men described seeking age-discordant relationships for the sole purpose of exchange sex. Older partners during first same-sex experience helped younger partners sort through sexual position and how to perform in relationships. These interviews suggest that YAAMSM may be seeking older partners to fulfill desires to be in a stable, emotionally mature relationship and for exposure in the larger community. Prevention strategies aimed at targeting adolescent MSM age-discordant relationships will need to address the interpersonal needs met within older sexual partnerships.

    This study aimed to determine the attitudes toward smoking and the characteristics of smoking patterns in young men of military age. Individuals performing their military service were surveyed using a self-administered, anonymous, personal and voluntary questionnaire. Questions were included on smoking habits, social context, and desire to quit. Responses were received from 386 (93.46%) subjects, all male, whose mean age was 20.52 +/- 2.3 years. The sample included 207 smokers (53.62%), 173 non smokers (44.81%) and 6 ex-smokers (1.55%). Mean age of initiation was 15.07 +/- 2.4 years and mean age of start of habitual smoking was 16.46 +/- 2.2 years. The main reasons for starting to smoke were curiosity (39.73%) and peer pressure (29.45%). Between 11 and 20 cigarettes/day were smoked by 53.74%. Those who began before 18 years of age smoked more than those who began after age 19. Light tobacco was smoked by 90.87%. Non smokers had fewer friends and family members who smoked than did smokers (p reason for increased smoking. We conclude that the prevalence of daily smoking is high among young men, who begin smoking regularly at 16 years of age. Those who begin later smoke less. The influence of friends and family members on initiation and maintenance of smoking is great. Half the smokers contemplated quitting and reported a high number of earlier attempts to stop. We believe that military quarters are an ideal place for health education and promotion, offering the possibility of designing special programs for decreasing the prevalence of smoking among adults.

    While the disproportionate impact of HIV on young black men who have sex with men (MSM) is well documented, the reasons for this disparity remain less clear. Through in-depth interviews, we explored the role of familial, religious, and community influence on the experiences of young black MSM and identified strategies that these young men use to negotiate and manage their sexual minority status. Between February and April 2008, 16 interviews were conducted among HIV-infected and HIV-uninfected young (19- to 24-year-old) black MSM in the Jackson, Mississippi, area. Results suggest that overall, homosexuality remains highly stigmatized by the men's families, religious community, and the African American community. To manage this stigma, many of the participants engaged in a process of "role flexing," in which individuals modified their behavior in order to adapt to a particular situation. The data also provided evidence of internalized homophobia among a number of the participants. The impact of stigma on risk behavior should be more fully explored, and future intervention efforts need to explicitly address and challenge stigma, both among young men themselves and the communities in which they reside. Attention should also be paid to the role masculinity may play as a driver of the HIV epidemic among young black MSM and how this knowledge can be used to inform prevention efforts.

    Young Black men who have sex with men (YBMSM) are at extraordinarily high risk for HIV infection. Given their dual minority identity, they experience multiple forms of social oppression-racism, homophobia, and poverty. This study tested a model for how these forces contribute to their sexual risk behavior. YBMSM (n = 1,289) from 2 Texas cities completed a 1-time assessment of sexual behaviors and psychosocial variables. Structural equation modeling was used to characterize relationships among variables. Experiences of racism, homophobia, and socioeconomic distress were all associated with unprotected anal intercourse (UAI) either directly or indirectly in a manner largely consistent with Díaz's (1997, 1998) model of the effects of social oppression. Racism, homophobia, and socioeconomic distress were each associated with specific psychological vulnerabilities, which were in turn associated with participation in difficult sexual situations (e.g., in a public setting), and then UAI. The effects of racism were largely mediated by depressive symptoms and participation in difficult sexual situations. Homophobia was mediated by depressive symptoms, social support, and internalized homophobia. The effects of socioeconomic distress were partially mediated by decreased social support and greater participation in difficult sexual situations. Socioeconomic distress also had a significant direct effect on UAI not explained by the proposed mediators. Social oppression contributes to YBMSM's psychological vulnerabilities, participation in difficult sexual situations, and their UAI. Interventions to reduce sexual risk in YBMSM should address socioeconomic disadvantage, homophobia, and racism, as well as the psychological challenges that social oppression creates for them.

  16. Factors influencing young men's decision to undergo health screening in Malaysia: a qualitative study

    Teo, Chin Hai; Ng, Chirk Jenn; White, Alan

    2017-01-01

    Objectives Uptake of health screening is low in men, particularly among those aged purposively sampled according to their ethnicity, job position, age and screening status in order to achieve maximal variation. Results Eight IDIs and five FGDs were conducted (n=31) and six themes emerged from the analysis. (1) Young men did not consider screening as part of prevention and had low risk perception. (2) The younger generation was more receptive to health screening due to their exposure to health information through the internet. (3) Health screening was not a priority in young men except for those who were married. (4) Young men had limited income and would rather invest in health insurance than screening. (5) Young men tended to follow doctors' advice when it comes to screening and preferred doctors of the same gender and ethnicity. (6) Medical overuse was also raised where young men wanted more screening tests while doctors tended to promote unnecessary screening tests to them. Conclusions This study identified important factors that influenced young men's screening behaviour. Health authorities should address young men's misperceptions, promote the importance of early detection and develop a reasonable health screening strategy for them. Appropriate measures must be put in place to reduce low value screening practices. PMID:28283491

  17. Harm concerns predict moral judgments of suicide: comment on Rottman, Kelemen and Young (2014).

    2014-10-01

    Two prominent theories offer different perspectives on the role of harm in moral cognition. Dyadic morality suggests that harm-related concerns are pervasive, whereas moral pluralism suggests that these concerns apply only to canonically harmful violations (e.g., murder), and not impure violations (e.g., suicide). Rottman et al. (2014) contrast these two theories by examining moral judgments of suicide. They conclude that suicide wrongness is independent of harm, therefore arguing against dyadic morality and for moral pluralism. However, these conclusions may be overstated; across all these studies, a meta-analysis reveals that harm is a significant predictor of suicide judgments. Moreover, the association between harm and suicide wrongness may be suppressed in individual studies by insufficient power, restrictive exclusion criteria, a single bivariate outlier, and reliance upon the conventional significance threshold of psuicide wrongness, consistent with dyadic morality.

  19. Activation of antioxidant defenses in whole saliva by psychosocial stress is more manifested in young women than in young men.

    Full Text Available Psychosocial stress has been long known to have deleterious effects on health. Nevertheless, an exposure to moderate stressors enhances resilience and promotes health benefits. Male and female organisms differ in many aspects of health and disease. The aim of this study was to investigate antioxidant activity and oxidative damage in saliva in a psychosocial stress paradigm in men and women. Here, we show that an acute stressor of moderate strength augments antioxidant activity and decreases oxidative damage in whole saliva of young people. An examination stress caused a significant increase of catalase activity, accompanied by a decrease of levels of oxidized proteins. Levels of thiobarbituric acid-reacting substances did not increase at stress, indicating that lipid peroxidation was not activated. The stress-induced alterations were more manifested in young women compared to young men. Thus, antioxidant protective mechanisms are more activated by a moderate stressor in young women than in young men.

    Full Text Available Behavioral surveillance surveys have been carried among military conscripts, in Brazil, since 1996. This paper presents the results of the 2007 survey and compares actual findings with those obtained in previous studies carried out in the period 1999-2002. The conscripts were selected with a two stage sampling stratified by geographical region. The study included a self-reported questionnaire and blood collection for HIV and syphilis testing. Data from 35,432 conscripts aged 17-20 years old were analyzed. The findings show a reduction in regular condom use, with fixed and casual partners, mainly among those with poor educational level. The proportion of conscripts that have sex with other men was maintained (3.2%, but the index of risky sexual behavioral showed worsening results in this group. Also, the HIV prevalence rate increased from 9 to 11.3 per 10,000 in 2007, though the increase was not statistically significant. In conclusion, the evidences found in this paper indicate the need of reformulate policy among young adults.

  1. Boys' and young men's perspectives on violence in Northern Tanzania.

    2013-01-01

    The challenge of violence for youth in low-income countries includes a range of experiences from witnessing, to experiencing, to participating in violence. Although boys and young men are often the perpetrators of such violence, they may also be its victims. Yet little evidence exists from the voiced experiences of boys themselves on perceptions and interpretations of the violence around them. Given the numerous negative health implications of violence for boys, for the girls and other boys with whom they interact, and for the health of their future partners and families, we conducted an in-depth study in rural and urban Tanzania with adolescent boys on the masculinity norms shaping their transitions through puberty that might be contributing to high-risk behaviours, including engagement in violence. The findings identified underlying societal gendered norms influencing the enactment of violence, and recommendations from the boys on how to diminish the violence around them. Additional research is needed with boys on the social norms and structural factors influencing their engagement in violence.

    Purpose Outcomes of treatment for young men compared with older men with prostate cancer are poorly defined outside of limited institutional series. This study examines the association between age at diagnosis and grade, stage, treatment, and survival outcomes in men diagnosed during the era of prostate-specific antigen testing. Patients and Methods The NCI SEER database was used to identify men diagnosed with prostate cancer between 1988 and 2003. Men aged 35-74 were stratified by age at diagnosis to examine differences in tumor characteristics, treatment, and survival within each age group. Results We identified 318,774 men ages 35 to 74 diagnosed with adenocarcinoma of the prostate between 1988 and 2003. The proportion of men age 55 and younger at diagnosis increased over the study period, from 2.3% between the years 1988-1991 to 9.0% between the years 2000-2003, and median age at diagnosis decreased from 72 in 1988 to 68 in 2003. Younger men were less frequently diagnosed with organ confined tumors (p<0.001), but less likely to be diagnosed with high grade cancer (p<0.001). Older men were more likely to receive no local therapy or external beam radiation than young men (p< 0.001 for trends). Among men with Gleason 5-7 tumors, overall survival was worse with advancing age. However, among all age groups with high grade and stage, the youngest men (35-44) were at the highest risk of all cause and cancer specific death. Conclusions Age at diagnosis among men with prostate cancer continues to decline. Younger men are more likely to be treated with prostatectomy, have lower grade cancer, and as a group have better overall, and equivalent cancer specific survival at 10 years compared to older men. Among men with high grade and locally advanced prostate cancer, the youngest men have a particularly poor prognosis compared to older men. PMID:19466697

    Young men who have sex with men (MSM) in Jamaica have the highest HIV prevalence in the Caribbean. There is little information about HIV among transgender women in Jamaica, who are also overrepresented in the Caribbean epidemic. HIV-related stigma is a barrier to HIV testing among Jamaica's general population, yet little is known of MSM and transgender women's HIV testing experiences in Jamaica. We explored perceived barriers and facilitators to HIV testing among young MSM and transgender women in Kingston, Jamaica. We implemented a community-based research project in collaboration with HIV and lesbian, gay, bisexual and transgender (LGBT) agencies in Kingston. We held two focus groups, one with young (aged 18-30 years) transgender women (n = 8) and one with young MSM (n = 10). We conducted 53 in-depth individual semi-structured interviews focused on HIV testing experiences with young MSM (n = 20), transgender women (n = 20), and community-based key informants (n = 13). We conducted thematic analysis to identify, analyze, and report themes. Participant narratives revealed social-ecological barriers and facilitators to HIV testing. Barriers included healthcare provider mistreatment, confidentiality breaches, and HIV-related stigma: these spanned interpersonal, community and structural levels. Healthcare provider discrimination and judgment in HIV testing provision presented barriers to accessing HIV services (e.g. treatment), and resulted in participants hiding their sexual orientation and/or gender identity. Confidentiality concerns included: clinic physical arrangements that segregated HIV testing from other health services, fear that healthcare providers would publicly disclose their status, and concerns at LGBT-friendly clinics that peers would discover they were getting tested. HIV-related stigma contributed to fear of testing HIV-positive; this intersected with the stigma of HIV as a "gay" disease. Participants also anticipated healthcare provider

    Objective To understand the current semen quality status among Chinese young men and influential factors in China and to explore its evaluation index. Methods A total of 562 healthy male volunteers were recruited during their premarital examinations in seven provincials and municipal regions' MCH centers; descriptive and principal component analyses were used to analyze data.Results The findings show that semen volume (2.61±1.10 mL), sperm density (64.47±34.59×106/mL), percentage of sperm forward progression (59.89%±17.11%), percentage of sperm viability (77.19%±11.87%), and percentage of normal sperm morphology (78.23%±9.15%). The first principal component function is Z1=-8.512 54 + 0.001 36X1' +0.031 92X2'+0.043 52X3'+ 0.039 84X4', which is closely related to percentage of sperm viability (X3), percentage of sperm forward progression (X2), and percentage of normal sperm morphology (X4);The second principal component function is: Z2=0.491 92+ 0.080 80X1- 0.000 58X2 - 0.005 10X3 - 0.018 07X4, which depends on the total sperm count (X1). Conclusion Only 42.3% subjects meet all the common WHO standard of semen quality. The multiple analysis of Z1 showed that the highest Z1 are among subjects from Guizhou, workers, or town residents. Multiple analysis of Z2 showed that the older age when the subjects had the first sexual impulse, the longer period of sexual abstinence and more quantity of sperm they had; the more sexual activity subjects had, the less amount of sperm they had.

  10. Just when we thought we were producing fine young men

    Full Text Available Literature is highly influenced by society and cultural contexts in which it is produced or read. It is a reflection of how a particular society constructs reality. The values, beliefs and norms transferred from one generation to another reflect, in the main, that society’s way of life. When creative writers use verbal art forms like novels, short stories or drama, they do so in order to create an allusive and fictitious setting which enable them to comment on contemporary issues without blatantly seeming to do so. In this sense it becomes a prerogative for artists to remark on what is happening in communities without being directly confrontational. In our view, it is also their responsibility to approach literature from an angle that reflects changing times, thus challenging anything that is contrary. In 2013 we involved our final year undergrad literature class in a project whose aim was to sensitize them on gender disparities still affecting our society today. Five of nine groups comprising ten students each – both men and women-chose to study the work of an acclaimed Zulu writer, D.B.Z. Ntuli (1982. Based on the comments of the male students in those groups the discussion was stretched to the entire class. It was perturbing to discover that we are still producing male students who are not sensitive to gender disparities. In this article we argue that indifference displayed by these young men where issues of gender were concerned call for attention. This article presents the callous treatment of women characters in the selected short story and examples of comments made by male students on their reading of the text. We also contend that we are still far from reaping the fruits of our hard -won democracy given that Zulu men in the study still seems to lack an understanding of basic human rights. Their failure to understand obvious gender-based violence as an intolerable social ill.En ons dog ons lewer pragtige jongmanne op. Literatuur word

    Clark County, Nevada had a 52% increase in newly diagnosed HIV infections in young people age 13-24 with 83% of the new diagnoses in this age group being men who have sex with men (MSM). HIV testing and counseling is critical for HIV prevention, care and treatment, yet young people are the least likely to seek HIV testing. The purpose of this study was to identify barriers and facilitators to HIV testing experienced by young MSM in Clark County, Nevada. We conducted a qualitative focus group discussion to identify barriers and facilitators to HIV testing among eleven young MSM in March, 2015. The primary barrier to HIV testing identified by the group was a lack of awareness or knowledge about testing for HIV. Other barriers within the person included: fear of results, fear of rejection, and fear of disclosure. Barriers identified within the environment included: access issues, stigma, and unfriendly test environments for young people. In addition to increasing awareness, intervention to increase HIV testing among MSM young people should incorporate access to testing in environments where the adolescents are comfortable and which reduces stigma. HIV testing sites should be convenient, accessible and young person/gay friendly.

  17. Young men's health promotion and new information communication technologies: illuminating the issues and research agendas.

    Science.gov (United States)

    Robinson, Mark; Robertson, Steve

    2010-09-01

    The article examines the use of newer, interactive information and communication technologies (ICTs) in young men's health promotion (HP), drawing on gender theory, HP research and evidence on young men's Internet usage. The focus is on highlighting an agenda for research in terms of emerging issues. New forms of social media ICT (for example 'web 2'-based on-line social networking sites, micro-blogging services, i-phones and podcasts) have the potential to enable young men to engage with health information in new and interesting ways. Given concerns about young men's engagement with health services, innovative ICT formats, particularly using the Internet, have been tried. However, issues persist around surfing 'addiction', quality control and equal access. Approaches to HP using new ICTs offer distributed control over information content and quality and a lay social context for accessing information. Online communities can potentially legitimize young men's participation in discourses around health, and support sustained engagement. The article discusses how this could support young men to re-conceptualize healthy choices in the context of masculine imperatives and responsible citizenship if specific conditions are met (for trusting engagement) and risks addressed (such as commercial disinformation). The skill requirements for young men to engage effectively with new ICTs are explored, focusing on health literacy (HL). It is predicted that social marketing approaches to HP for young men will increasingly include new ICTs, making specific requirements for HL. These approaches may appeal narrowly to hegemonic masculinities or broadly to multiple masculinities, including those historically marginalized. Recommendations are made for future research.

  18. Between '0' and '1': safer sex and condom use among young gay men in Hong Kong.

    Yeo, Tien Ee Dominic; Fung, Tsz Hin

    2016-01-01

    Young men who have sex with men are becoming the most at-risk subgroup for HIV incidence in Hong Kong. To understand how young gay men in Hong Kong interpret and implement safer sex and condom use, focus-group discussions and individual in-depth interviews were held. The 74 participants were nearly all ethnic Chinese gay men aged between 18 and 25 years. Findings indicate that the challenge for health intervention lies in young gay men's inconsistent condom use despite their high level of HIV-related knowledge. Participants described using condoms, testing for HIV and abstaining from anal sex as measures undertaken to prevent HIV infection. However, sociocultural norms and expectations pertaining to '0' (docile, bottom) and '1' (assertive, top) roles and trust between partners complicate the consistent implementation of risk-reduction measures. Influenced by heteronormative and romantic beliefs, sexual behaviours such as condomless anal sex and internal ejaculation hold symbolic meanings - exclusivity, commitment, intimacy, possession - for young gay men in Hong Kong, which override health concerns. These findings support more empowerment-driven HIV programming for young gay men.

    Rasmussen, Mette L; Haavind, Hanne; Dieserud, Gudrun; Dyregrov, Kari

    2014-01-01

    This study explores the developmental history of ten young men who completed suicide in the transition to adulthood. The young men, aged 18-30, had no previous history of suicide attempts or treatment in mental health. In-depth interviews with four to eight informants for each suicide were analyzed using Interpretative Phenomenological Analysis. Three developmental issues from early age onwards emerged: (a) unsuccessful in becoming independent; (b) weakened competence to deal with shame; and (c) trapped in anger. The capacity to regulate emotions like shame and anger could make certain men vulnerable to suicide when facing adult challenges and defeats.

    2017-07-01

    A growing body of evidence focuses on the experiences of young men in low-income countries, including their health vulnerabilities. Much of this research has been conducted in sub-Saharan Africa, Asia and Latin America. Limited evidence exists on the norms influencing boys' transitions into young adulthood in Southeast Asia, and in Cambodia in particular. To help fill this gap, we conducted a comparative case study using participatory methods with 16-19-year-old young men in rural and urban Cambodia, and with the adults who intersect in their lives. Findings suggest that in line with their counterparts growing up elsewhere, Cambodian boys welcome becoming young men as a time of newly acquired adult roles and responsibilities, while some may experience growing up as a time of bodily change, burgeoning sexual feelings and limited sources of support and guidance. As a result, some may strive more intensely to conform to the alcohol use and violence modelled by the older men in their environments. Additional research is needed to better understand the vulnerabilities of boys' transition into young adulthood in Cambodia today, and how to prevent or reduce engagement with these more negative practices.

    The decline in the employment status of young black men relative to their white peers in the post-1970 U.S. Labor market is the impetus for this research. This paper examines the effects of recent employment restructuring on young workers by race and sex. In the case of the least educated group of young black men (aged 25-34), the employment-to-population ratio declined by almost 35 percent (equivalent to 28 percentage points) from 1970 tol985. Moreover, the 1980s were a stark reversal to the...

    Full Text Available Abstract Background We investigated the accessibility of reproductive health information and contraceptives in a relatively less developed area of rural central India and assessed the risks facing young unmarried men. Methods This cross-sectional study used both qualitative and quantitative methods. Participants included 38 unmarried rural men in four focus-group discussions and a representative sample of 316 similarly profiled men, aged 17-22 years, in a survey. Information was collected on the men's socioeconomic characteristics; awareness, knowledge, and perceptions of family planning; attitudes toward future contraceptive use; intra-family communication; knowledge about STIs/HIV/AIDS; and access and use of condoms. Content analysis for qualitative information and descriptive analysis for survey data were used to draw conclusions. Results Young unmarried rural Indian men's sexual and reproductive health (SRH knowledge is limited, although the majority is familiar with condoms (99%. The young men identified electronic mass media (67% as the prime source of reproductive health information, yet they lacked detailed knowledge of various contraceptives and felt ignored by health providers, who, they felt, would be capable of providing SRH information through interpersonal communication. Young men are more concerned about avoiding infections and securing sexual pleasure and less concerned about avoiding potential pregnancies. For example, 68% of the young men were aware of condoms and their HIV/AIDS preventive role, but only about two-fifths mentioned condom use to prevent unwanted pregnancies. Although most young men (96% knew where to access a condom, they felt uncomfortable or embarrassed doing so in their own villages or close by because of socio-cultural norms that prevented them from using contraceptives. Very few respondents (4% disclosed using condoms themselves, but 59% said they knew someone from their peer group who had used them

    We investigated the accessibility of reproductive health information and contraceptives in a relatively less developed area of rural central India and assessed the risks facing young unmarried men. This cross-sectional study used both qualitative and quantitative methods. Participants included 38 unmarried rural men in four focus-group discussions and a representative sample of 316 similarly profiled men, aged 17-22 years, in a survey. Information was collected on the men's socioeconomic characteristics; awareness, knowledge, and perceptions of family planning; attitudes toward future contraceptive use; intra-family communication; knowledge about STIs/HIV/AIDS; and access and use of condoms. Content analysis for qualitative information and descriptive analysis for survey data were used to draw conclusions. Young unmarried rural Indian men's sexual and reproductive health (SRH) knowledge is limited, although the majority is familiar with condoms (99%). The young men identified electronic mass media (67%) as the prime source of reproductive health information, yet they lacked detailed knowledge of various contraceptives and felt ignored by health providers, who, they felt, would be capable of providing SRH information through interpersonal communication. Young men are more concerned about avoiding infections and securing sexual pleasure and less concerned about avoiding potential pregnancies. For example, 68% of the young men were aware of condoms and their HIV/AIDS preventive role, but only about two-fifths mentioned condom use to prevent unwanted pregnancies. Although most young men (96%) knew where to access a condom, they felt uncomfortable or embarrassed doing so in their own villages or close by because of socio-cultural norms that prevented them from using contraceptives.

    Young black men who have sex with men account for 48% of 13-29-year-old HIV-positive men who have sex with men in the USA. It is important to develop an effective HIV prevention approach that is grounded in the context of young men's lives. Towards this goal, we conducted 31 interviews with 18-30-year-old men who have sex with men in the San Francisco-Oakland Bay Area. This paper examines the roles of religion and spirituality in men who have sex with men's lives, which is central in the lives of many African Americans. Six prominent themes emerged: (1) childhood participation in formal religious institutions, (2) the continued importance of spirituality among men who have sex with men, (3) homophobia and stigmatisation in traditional black churches, (4) tension between being a man who has sex with men and being a Christian, (5) religion and spirituality's impact on men's sense of personal empowerment and coping abilities and (6) treatment of others and building compassion. Findings suggest that integrating spiritual practice into HIV prevention may help programmes be more culturally grounded, thereby attracting more men and resonating with their experiences and values. In addition, faith-based HIV/AIDS ministries that support HIV-positive men who have sex with men may be particularly helpful. Finally, targeting pastors and other church leaders through anti-stigma curricula is crucial.

    Rapid socioeconomic transformation in Vietnam in last 15 years has been followed by more liberation of sexual expression and representation of sexual identity among young people. There has been an increase in the visibility of homosexual men in major cities of Vietnam who were largely an unknown population until the emergence of the HIV epidemic. Men who have sex with men (MSM) are now considered as one of the target groups in many HIV prevention programs. This qualitative study examines local identities, relationships, and sexual practices among young MSM aged 15-24 in the cities of Hanoi and Ho Chi Minh City. Our analyses were based on 26 in-depth interviews and 10 focus group discussions with young MSM recruited through public place intercepts and cruising areas. Data document the linguistic classification, sexual relationships and behaviors, identity and process of homosexual identification, and the potential linkage between sexual identity and sexual behaviors of MSM in Vietnam. Data also highlight the stages of homosexual community development in urban Vietnam and important differences between Vietnam and the West in the representation of homosexual identity, relationships, and practices. In light of the findings, we suggest that the continuing development and elaboration of a homosexual community in Hanoi and Ho Chi Minh City offers significant opportunities for targeted HIV/AIDS prevention activities in the Vietnamese MSM population.

    This essay chooses as its texts three films representing contemporary gay male subjects from each of the "three" China's: HK, Taiwan, and the Mainland. Relocating the homoerotic image of the "sad young man," a trope popular from Hollywood rebellion films of the 1950s and 1960s, to contemporary China, I discuss how this masculine icon has been transformed from one of heroic rebellion to one of existential isolation. Indeed, as the politics of both the outmoded Confucian family and fractured Chinese nationhood intersect, what the sad young (gay) man rebels against is a political fluctuation which is no longer fixed; as the young man's opposition is no longer fixed, so too does he become alienated even from his own rebellious cause.

    One hundred and sixty-six young military man with mitral valve prolapse (MVP) aged 19.2+/-0.8 years were examined. Complex system approach to health status was applied to study clinico-functional features of this condition in young military men. The study found that clinico-functional manifestations of MVP in young military men reflected a multifocal character of dysadaptation during the first stages of military service. Conditions of professional military activity potentiate permanent progress of crisp prolapse as well as the severity of mitral regurgitation, structural and functional myocardial alterations, and myocardial electric instability increasing in the presence of abnormal cardiac chords under the influence of a prominent vegetative dysfunction. The reserve of the cardiorespiratory system and the entire organism in military men with MVP was lowered. The study registered inadequate hemodynamic responses to functional orthostatic test and physical load test, typical for hyperventilation syndrome.

    The association of occupational exposure to current-use pesticides with reproductive hormones, semen quality, and genital measures was investigated among young men in the South of Brazil. A cross-sectional study was conducted in 99 rural and 36 urban men aged 18-23 years. Information on pesticide use was obtained through questionnaire. Serum and semen samples were analyzed for sex hormones and sperm parameters, respectively, and measurement of anogenital distance (AGD) and testis volume (TV) were performed. Associations were explored using multivariate linear regression. Rural men had poorer sperm morphology, higher sperm count, and lower LH levels relative to urban subjects. Lifetime use of pesticides, especially herbicides and fungicides, was associated with poorer morphology and reduced LH and prolactin, with evidence of a linear pattern. Maternal farming during pregnancy was associated with larger AGD and TV. Chronic occupational exposure to modern pesticides may affect reproductive outcomes in young men.

    The prevalence of HIV infection is disproportionately higher in both racial/ethnic minority men who have sex with men (MSM) and in men under the age of 25, where the leading exposure category is homosexual contact. Less is known, however, about patterns of HIV prevalence in young racial/ethnic minority MSM. We analyzed data from the Young Men's Survey (YMS), an anonymous, cross-sectional survey of 351 MSM in Baltimore and 529 MSM in New York City, aged 15-22, to determine whether race/ethnicity differences exist in the prevalence of HIV infection and associated risk factors. Potential participants were selected systematically at MSM-identified public venues. Venues and associated time periods for subject selection were selected randomly on a monthly basis. Eligible and willing subjects provided informed consent and underwent an interview, HIV pretest counseling, and a blood draw for HIV antibody testing. In multivariate analysis, adjusted for city of recruitment and age, HIV seroprevalence was highest for African Americans [adjusted odds ratio (AOR) = 12.5], intermediate for those of "other/mixed" race/ethnicity (AOR = 8.6), and moderately elevated for Hispanics (AOR = 4.6) as compared to whites. Stratified analysis showed different risk factors for HIV prevalence in each ethnic group: for African Americans, these were history of sexually transmitted diseases (STDs) and not being in school; for Hispanics, risk factors were being aged 20-22, greater number of male partners and use of recreational drugs; and for those of "other/mixed" race/ethnicity, risk factors included injection drug use and (marginally) STDs. These findings suggest the need for HIV prevention and testing programs which target young racial/ethnic minority MSM and highlight identified risk factors and behaviors.

    Human adult aging is associated with a loss of strength, contractile velocity and hence, power. The principal plantar flexors, consisting of the bi-articular gastrocnemeii and the mono-articular soleus, appear to be affected differently by the aging process. However, the age-related effect of knee joint angle on the torque-angular velocity relationship and power production of this functionally important muscle group is unknown. The purpose was to determine whether flexing the knee, thereby reducing the gastrocnemius contribution to plantar flexion, would exacerbate the age-related decrements in plantar flexion power, or shift the torque-angular velocity relationship differently in older compared with young men. Neuromuscular properties were recorded from 10 young (~25 y) and 10 old (~78 y) men with the knee extended (170°) and flexed (90°), in a randomized order. Participants performed maximal voluntary isometric contractions (MVCs), followed by maximal velocity-dependent shortening contractions at pre-set loads, ranging from 15 to 75% MVC. The young men were ~20-25% stronger, ~12% faster and ~30% more powerful than the old for both knee angles (Ptorque was ~17% greater in the extended than flexed knee position, with no differences in voluntary activation (>95%). The young men produced 7-12% faster angular velocities in the extended knee position for loads ≤30% MVC, but no differences at higher loads; whereas there were no detectable differences in angular velocity between knee positions in the old across all relative loads. For both knee angles, young men produced peak power at 43.3±9.0% MVC, whereas the old men produced peak power at 54.8±7.9% MVC. These data indicate that the young, who have faster contracting muscles compared with the old, can rely more on velocity than torque for generating maximal power.

    The mechanism by which homocysteine (Hcy) causes endothelial dysfunction is probably mediated by oxidative stress. The aim of this study was to evaluate the effect of oxidative stress on endothelial function in young and elderly hyperhomocysteinemic (HHcy) men. A total of 35 HHcy (Hcy > 15 micro mol/L), young (n = 15; 20-40 y) and elderly men (n = 20; > 65 y) and 33 normohomocysteinemic (NHcy; controls) young (n = 14) and elderly (n = 19) men (Hcy < 13 micro mol/L), without classic cardiovascular risk factors were recruited. Serum Hcy, folate, and vitamin B-12, whole-blood glutathione, plasma total antioxidants status, TBARS, and 8-F(2alpha) isoprostanes were determined. Noninvasive ultrasound measurements of endothelium-dependent (EDVR) and -independent dilatation (EIVR) were performed. EDVR, EIVR, and markers of oxidative stress did not differ among the groups. Folate concentrations were higher in elderly than in young men (P < 0.001), independent of Hcy concentrations. Vitamin B-12 concentrations were lower in HHcy than in NHcy elderly men (P < 0.045). EDVR was correlated with folate concentrations in young men (r = 0.40, P = 0.04) and negatively with BMI in elderly men (r = -0.52, P = 0.002). In the present study, HHcy with normal serum folate concentrations was not associated with poor EDVR or oxidative stress in healthy young and elderly men.

    We explored how young men's perceptions of and participation in hip hop culture--urban social and artistic expressions, such as clothing style, breakdancing, graffiti, and rap music--and how contextual factors of the hip hop scene may be associated with their condom use, condom-use self-efficacy, and sense of community. We conducted a cross-sectional survey of 95 African American and Latino men aged 15 to 25 years as part of a 4-year ethnographic study in New York City. Differences in young men's perceptions of and levels of affiliation with hip hop culture were not statistically associated with differences in their sense of community or condom-use self-efficacy. Frequency of participation in the hip hop nightclub scene was the strongest factor negatively associated with condom use. Popular discourses on young men's health risks often blame youths' cultures such as the hip hop culture for increased risk practices but do not critically examine how risk emerges in urban young men's lives and what aspects of youths' culture can be protective. Further research needs to focus on contextual factors of risk such as the role of hip hop nightlife on increased HIV risk.

    Latinos have been disproportionately affected by HIV, placing young Latino men who have sex with men (MSM) at increased risk within this ethnic community. The study explored the lived experience of growing up as a young Latino MSM and motivators to HIV risk behaviors. Five young Latino MSM ages 18 to 25 years were enrolled in a qualitative, phenomenological study using semistructured interviews followed by a HIV risk-taking behavior survey. A relationship was identified between patterns of belonging and self-acceptance of sexual orientation and motivators of HIV sexual risk-taking behavior. La familia, machismo, hiding, and guilt were themes related to belonging and self-acceptance. The need to belong and be accepted by the family and self-acceptance of sexual orientation are related to the HIV sexual risk-taking behavior of young Latino MSM.

  4. When men appear smaller or larger than they really are: preliminary evidence that women are fooled by size illusions in attractiveness judgment tasks

    Ludwig Yannick S.

    2014-12-01

    Full Text Available In humans, studies have shown that contrast illusions can affect perceptions of facial attractiveness and dominance. In non-human animals, recent research found that contrast illusions of size positively affected male mate value. In humans, male height is a potentially important indicator of mate value, with women preferring men taller than themselves. We tested in two studies whether height contrast illusions could affect women’s perceptions of male height and mate value, particularly attractiveness, dominance, and muscularity. Using computer-generated images of men of different heights standing in groups of three, 104 female participants rated targets either surrounded by shorter, same height, or taller distractors in a within-subject design. The second experiment (N=80 replicated and extended the first by making the images more realistic and adding natural backgrounds, suggesting that when participants are given a visual anchor, in order to get a better sense of the absolute height of the targets, the effects remain. In both studies, results showed that, compared with same height distractors, male targets were rated as taller when surrounded by shorter distractors, and as shorter when surrounded by taller distractors. Additionally, attractiveness, dominance, and muscularity perceptions were affected in a similar manner, with most of the differences in these appraisals being mediated by the perceived height differences. Therefore, differently sized distractors affected the perceived height and mate value of the targets, which were in effect all of the same constant size. These findings indicate that context dependent effects could potentially influence attractiveness judgments. The same man might thus be perceived as more attractive when surrounded by men of similar or smaller height, as opposed to when surrounded by men who are taller.

  5. The impact of childhood gender expression on childhood sexual abuse and psychopathology among young men who have sex with men.

    Young men who have sex with men (MSM) are a risk group highly vulnerable to HIV infection and psychiatric symptoms are direct predictors of sexual risk behavior in MSM. Childhood sexual abuse (CSA) is associated with psychiatric symptomology in adolescence, and MSM are disproportionately impacted by CSA compared to heterosexuals. Some evidence suggests that childhood gender nonconformity, a natural variation of human gender expression, is more common in MSM than heterosexual males and places MSM at greater risk for CSA. This study examined whether or not childhood gender expression moderated the association between incidents of unwanted, early sexual experiences occurring before age 13 (ESE) and current psychiatric symptomology in a community-based sample of 449 young MSM aged 16-20. Analyses revealed significant bivariate associations between ESE and psychological symptoms, and significant multivariable associations between ESE, gender nonconformity and psychiatric outcomes. Young MSM with childhood gender nonconformity may be disproportionately victimized by CSA thereby increasing their likelihood of developing psychiatric symptoms in adolescence. Early intervention addressing these factors may help reduce lifetime negative sequelae.

    This study compared the postprandial triacylglycerol (TAG) response to a high-fat meal in trained and untrained normolipidemic young adults after 2 days' abstinence from exercise. Fifty-three subjects (11 endurance-trained men, 9 endurance-trained women, 10 sprint/strength-trained men, 11 untrained men, 11 untrained women) consumed a meal (1.2 g fat, 1.1 g carbohydrate, 66 kJ per kg body mass) after a 12-h fast. Venous blood samples were obtained in the fasted state and at intervals until 6 h. Postprandial responses were the areas under the plasma or serum concentration-vs.-time curves. Neither fasting TAG concentrations nor the postprandial TAG response differed between trained and untrained subjects. The insulinemic response was 29% lower in endurance-trained men than in untrained men [mean difference -37.4 (95% confidence interval -62.9 to -22.9) microIU/ml x h, P = 0.01]. Responses of plasma glucose, serum insulin, and plasma nonesterified fatty acids were all lower for endurance-trained men than for untrained men. These findings suggest that, in young adults, no effect of training on postprandial lipemia can be detected after 60 h without exercise. The effect on postprandial insulinemia may persist for longer.

    To assess internalized homophobia (IH) and its relationship to sexual risk behaviors and prevalence of sexually transmitted infection (STIs) in a clinic-based sample of young black men who have sex with men (YBMSM). Six hundred YBMSM completed a self-interview and provided specimens for testing. A 7-item scale assessed IH, and 19 sexual risk behaviors were assessed. In adjusted models, compared with men with less IH, those with greater IH were more likely to report: any condomless anal receptive sex (P = 0.01) and sex with women (P < 0.001). Alternatively, men with greater IH were less likely to: discuss acquired immune deficiency syndrome prevention with sex partners (P = 0.009), disclose their same sex sexual behavior to providers (P = 0.01), be tested for human immunodeficiency virus in the past 12 months (P = 0.04), report condomless oral sex (P = 0.049), and test RPR positive (P = 0.01). With some exceptions, IH among YBMSM attending STI clinics may influence their sexual risk behaviors; however, STI prevalence was not associated with this construct.

    Objective To understand the spread of HIV among and between age and racial/ethnic groups of men who engage in male-to-male sexual contact (men who have sex with men, MSM) in the United States. Design Analysis of HIV-1 pol sequences for MSM collected through the U.S. National HIV Surveillance System (NHSS) during 2001–2012. Methods Pairwise genetic distance was calculated to determine potential transmission partners (those with very closely related nucleotide sequences, i.e., distance ≤1.5%). We described race/ethnicity and age of potential transmission partners of MSM. Results Of 23,048 MSM with HIV sequences submitted to NHSS during 2000–2012, we identified potential transmission partners for 8,880 (39%). Most potential transmission partners were of the same race/ethnicity (78% for blacks/African Americans, 64% for whites, and 49% for Hispanics/Latinos). This assortative mixing was even more pronounced in the youngest age groups. Significantly fewer young black/African American and Hispanic/Latino MSM had older potential transmission partners compared with young white MSM. Conclusion Black/African American MSM, who are more profoundly affected by HIV, were more likely to have potential HIV transmission partners who were of the same race/ethnicity and similar in age, suggesting that disparities in HIV infections are in large part not due to age-disassortative relationships. Concerted efforts to increase access to pre-exposure prophylaxis, quality HIV care, and effective treatment are needed to interrupt transmission chains among young, black/African American MSM.

    The Canadian Physiotherapists in Hemophilia Care (CPHC) sought to learn about attitudes and behaviours of young male adults with mild haemophilia towards their condition and care. Semi-structured in-person or telephone interviews were conducted with 18 young men from and across Canada. This report summarizes the participants' attitudes towards their haemophilia, previous injuries, perceived barriers to seeking treatment, as well as their decision-making process when self-assessing injury. The interviews demonstrated that communication between the young adults and the health care team was not optimal, with common reference to the ineffectiveness of lecture style education. Gaps in knowledge also emerged regarding bleed identification and management.

    There is controversy as to whether there are sex differences in arterial stiffness. Acute physical stress can elicit vascular abnormalities not present at rest. Our objective was to assess sex differences in arterial stiffness at rest and in response to acute physical stress. Healthy young men (n=67) and women (n=55) underwent pulse wave analysis and carotid-femoral pulse wave velocity measurements at rest and 2, 5, 10 and 15 min following an exercise test to exhaustion. At rest, aortic systolic, diastolic, pulse and mean pressures were all significantly higher in men as was aortic pulse pressure at 10 and 15 min post exercise and aortic systolic pressure at 15 min. Carotid-femoral pulse wave velocity was significantly higher in men (6.0±0.7 m s(-1) vs. 5.6±0.6 m s(-1), P=0.03) at rest and at all time points post exercise. Heart rate-adjusted augmentation index was significantly lower (-10.7±10.2% vs. -4.0±10.9, Psex differences in the arterial stiffness response to acute physical stress in young men and women. Although we were not able to elicit differences in vascular function after adjustment, which were not present at rest, we found that young men and women exhibit differences in arterial stiffness at rest and after acute physical stress.

Healthy young men with untested fertility (n = 215). A physical examination, blood and semen samples, and completion of a questionnaire. Semen quality parameters. Physical activity was not related to semen quality parameters. The adjusted percentage differences (95% confidence interval) in semen parameters comparing men in the top quartile of moderate-to-vigorous physical activity (≥9.5 h/wk) with men in the bottom quartile (≤3 h/wk) were 4.3% (-30.2%, 38.9%) for total sperm count, 7.2% (-30.6%, 45.1%) for sperm concentration, -2.42% (-6.53%, 1.69%) for sperm motility, and 12.6% (-12.0%, 37.2%) for sperm morphology. In contrast to previous research among athletes, these data suggest that physical activity is not deleterious to testicular function, as captured by semen quality parameters in this population of healthy young men in Spain.

    Several studies have demonstrated that blacks exhibit elevations in systemic oxidative stress. However, the source(s) and mechanism(s) contributing to the elevation in oxidative stress remain unclear. Given that peripheral blood mononuclear cells (PBMCs) can be a major source of NADPH oxidase-derived superoxide production, we tested the hypothesis that young black men demonstrate greater superoxide production and NADPH oxidase expression in PBMCs compared with whites. PBMCs were freshly isolated from whole blood in young normotensive black (n = 18) and white (n = 16) men. Intracellular superoxide production in PBMCs was measured using dihydroethidium fluorescence, protein expression of NADPH oxidase subunits, gp91(phox) (membranous) and p47(phox) (cytosolic) in PBMCs were assessed using Western blot analysis, and plasma protein carbonyls were measured as a marker of systemic oxidative stress. Black men showed elevated intracellular superoxide production (4.3 ± 0.5 vs. 2.0 ± 0.6 relative fluorescence units; black men vs. white men, P superoxide production or NADPH oxidase subunit protein expression. These findings indicate that black men exhibit greater resting PBMC-derived superoxide production and an upregulation of the NADPH oxidase pathway with a possible contribution to increases in systemic oxidative stress.

  13. Sulforaphane Treatment of Young Men with Autism Spectrum Disorder.

    2016-01-01

    Autism Spectrum Disorder (ASD) comprises a heterogeneous group of neurodevelopmental disorders that begin in early childhood. They are characterized by differences in behavior and delays in communication and affect at least 1% of children. Observational studies have now confirmed that behaviors of a substantial percentage of children with autism tend to improve with the onset of febrile illness, which might be the downstream effects of altered metabolic pathways involving increased expression of heat shock proteins (HSP) and cellular stress responses. Sulforaphane, a phytochemical derived from a number of cruciferous vegetables, most notably broccoli sprouts, has metabolic effects that in some ways resemble that of fever. This review paper discusses this "fever effect" and the intracellular effects of sulforaphane as well as the results of our recent clinical trial of sulforaphane in young adults with autism. The accompanying review by Liu et al. describes the cellular actions of sulforaphane and potential biomarkers in the study of ASD.

    Alcohol use is correlated with unprotected sex, which may place young men who have sex with men (YMSM) who use alcohol with sex at increased risk for contracting HIV. However, little is known about how this link develops. This study used qualitative interviews to explore how alcohol became associated with sex and sexual risk among YMSM. We purposively sampled 20 Black and 20 Latino YMSM (N = 40), ages 21 to 24, who used substances (alcohol, marijuana, and crystal methamphetamine) with sex. Interviews focused on participants' personal histories to trace how these associations developed for each individual. Drawing on sexual script, emotion regulation, and alcohol expectancy theories, analyses followed a modified grounded theory approach. Participants stated that alcohol enabled them to engage in sexual behaviors with men that they wanted to try, allowing them to be more "bold," overcome stigma about homosexuality, and feel increased comfort with their sexual desires and identities. The use of alcohol during sex was helpful to some of the participants but could also lead to sexual risk behaviors. Intervention programs seeking to reduce alcohol misuse and sexual risk should take into account how YMSM conceptualize associations between alcohol and sex. These programs may be more effective if they provide support for sexual identity exploration.

  15. Impaired memory retrieval after psychosocial stress in healthy young men.

    Glucocorticoids (GCs) are known to modulate memory in animals and humans. One popular model suggests that stress or GC treatment enhances memory consolidation while impairing delayed memory retrieval. Studies in humans have documented that treatment with GCs impairs delayed memory retrieval. Similar alterations after exposure to stress have not been observed thus far. In the present study, 19 young healthy male subjects were exposed to either a standardized psychosocial laboratory stressor (Trier Social Stress Test) or a control condition in a crossover manner. After both treatments, retrieval of a word list (learned 24 h earlier) containing 10 neutral, 10 negative, and 10 positive words was tested. The stressor induced a significant increase in salivary free cortisol and a decrease in mood. Memory retrieval (free recall) was significantly impaired after the stress condition. Follow-up analysis revealed that negative and positive words (i.e., emotionally arousing words) were affected, whereas no effect was observed for neutral words. No changes were detected for cued recall, working memory, or attention. The present study thus demonstrates that psychosocial stress impairs memory retrieval in humans and suggests that emotionally arousing material is especially sensitive to this effect.

    Young gay, bisexual, and other men who have sex with men (MSM) experience sexual health disparities due to a lack of support in settings that traditionally promote positive youth development. The Internet may help to fill this void, but little is known about how it is used for sexual health purposes among young MSM. This mixed-methods study reports quantitative results of a large survey of 18- to 24-year-old MSM in an HIV testing clinic (N = 329) as well as qualitative results from interviews. Level of Internet use was high in this sample and the majority of participants reported using the Internet to find HIV/AIDS information. Black and Latino youth used the Internet less frequently than White youth, and after controlling for age, education, and frequency of Internet use, Black youth were 70% less likely to use the Internet to find HIV/AIDS information. Qualitative analyses identified themes related to the role of the Internet in finding sexual health information, sexual minority identity development, and sexual risk taking behaviors. Participants reported that the Internet filled an important and unmet need for sexual health education. It allowed for connections to the gay community and support during the coming out process, but also exposure to homophobic messages. There was no evidence of increased risk behaviors with partners met online, but at the same time the potential for the use of the Internet to facilitate safer sex communication was largely untapped. Our findings generally present an optimistic picture about the role of the Internet in the development of sexual health among young MSM.

    Qualitative data can be a powerful tool in developing interventions for substance use and other HIV-risk behaviors. Mixed methods design offers researchers the ability to obtain data that provides both breadth and depth to their research questions. However, the integration of qualitative data in mixed methods research has been limited. This paper describes the qualitative study design of the Healthy Young Men's Study, a longitudinal mixed method study with an ethnically diverse cohort of young men who have sex with men (YMSM) (N = 526) in Los Angeles. Integral to this discussion is how a mixed methods study can address common challenges such as sampling, representation and integration of both datasets.

    Resistance to insulin actions is contributing to many metabolic disturbances. Such factors as age, sex, nutrition, body fat, and physical activity determine body insulin resistance. Present study attempted to asses insulin resistance and its metabolic effects with respect to energy intake in young, lean, and active men. A total of 87 men aged 18-23 participated in the study. Plasma levels of glucose, insulin, lipoproteins, cortisol, and TSH were determined. Insulin resistance was expressed as Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) and calculated using homeostatic model. The median value of HOMA-IR (1.344) was used to divide subjects into two groups. Men did not differ in anthropometric parameters, daily physical activity, and plasma TSH and cortisol levels. However, in men with higher HOMA-IR significantly lower daily energy intake was observed concomitantly with higher TG, TC, and HDL-C concentrations in plasma versus their counterparts with lower HOMA-IR. Exclusively in subjects with higher HOMA-IR significant and positive correlation was noted between HOMA-IR and TC and LDL-C. We concluded that despite a normal body weight and physical activity, a subset of young men displayed unfavorable changes in insulin sensitivity and lipid profile, probably due to insufficient energy intake.

    Full Text Available Background: Young men with mental health problems often do not present to traditional primary care services. Novel methods to engage this population need to be explored. Between April and July 2005, Croydon Primary Care Trust developed a depression service for men aged 18 to 35 years. Part of this service was a mail-shot to all men in this age group registered with two general practices. The mail-shot informed them of the symptoms of depression, the importance of seeking help and where to obtain help. The objective of this research was to determine whether this mail-shot influenced the number of young men presenting to primary care with depression. Method: This was a before and after study. The quarterly incidences of depression in men aged 18 to 35 years was calculated from January 2000 to June 2005. Incidence risk ratios were calculated to compare pre-mail-shot incidence with the post mail-shot incidence. The cost of the mail-shot was calculated. Results: There were 148 new cases of depression diagnosed between January 2000 and June 2005 across the practices. There was a statistically significant increase in depressed young men contacting the two participating general practices in the quarter after the mail-shot compared with previous quarters (IRR 2.57; 95% CI 1.59-4.17; p < 0.001. The cost of the mail-shot was £1.00 per registered man aged between 18 and 35 years, or £297 (450 € per case of depression detected. Conclusion: Mail-shots may be a cost-effective way to encourage this traditionally 'hard-to-reach' group to consult primary care professionals for depression treatment.

    What are the parameters of semen quality in Baltic men? Combined parameters of sperm concentration, motility and morphology revealed that 11-15% of men had low semen quality, 37-50% intermediate and 38-52% high semen quality. Previous studies have revealed regional differences in semen parameters, and semen quality of Baltic men has been suggested to be better than that of other European men. This was a cross-sectional study of 1165 men aged 16-29 years from Estonia (N = 573), Latvia (N = 278) and Lithuania (N = 314) conducted in 2003-2004. Men from the general population, median age 19.8 years, provided one semen sample each, had blood samples taken, had testis size determined, and provided information on lifestyle. Based on combined data of sperm concentration, sperm motility and morphology the cohort was classified into three categories: low, intermediate or high semen quality. Comparisons between groups (including subgroups of Estonian men of Russian versus Estonian ethnicity) were tested, adjusting for ejaculation abstinence and age. The median sperm concentration of the Estonian, Latvian and Lithuanian populations of Baltic men was 63 mill/ml. Low semen quality was detected in 11-15% of the men, intermediate in 37-50% and high in 38-52%. No crucial differences between national subgroups were detected, except that a higher percentage (9.6%) of the subgroup of Russian Estonians reported having had cryptorchidism compared to the other men (2.5-3.6%, P 10 years ago. Thus, a recent change in semen quality cannot be excluded. Owing to the study design, it is assumed, but unproven, that the men were representative of the general populations. Some men were very young (16 years), however, this was also the case for other European studies of similar populations. Assessment of sperm motility is associated with inter-observer variation, and no quality control was undertaken for sperm motility assessment to account for that. Thus, estimates of sperm motility should be

    Young men who have sex with men (YMSM) face myriad challenges when deciding to disclose their sexual orientation to family members. Key to this decision is consideration of how disclosure may influence the support they receive from family. This paper explores a diverse sample of YMSM's (N = 43) perspectives on disclosure of their same-sex attractions to key family members and its impact on family support. Several stages/categories of disclosure are described and some YMSM seemed to continue to move between categories. Additionally, relationships after disclosure included negotiations between the expression of their sexual orientation and the maintenance of family support.

    Perception of Masculinity plays an important role in men's lifestyles and health behaviors. Although, the importance of masculinity has been widely discussed in men's health literature, very little is known about the meanings of masculinity in the Malaysian setting. This research aimed to explore the meanings of masculinity among Malaysian university men. This qualitative study utilized in-depth interviews with 34 young Malaysian university men, aged 20-30 years from three main ethnic groups in Malaysia (Malay, Chinese and Indian). Thematic analysis approach was used to extract data. NVIVO v8 qualitative software was used for data management. From the data collected several concepts emerged that reflected the meanings of masculinity from the participants' view points. These meanings were associated with a combination of traditional and non-traditional norms that generally benefit men who behave according to culturally dominant role expectations. These included: "Having a good body shape", "being respected", "having success with women", "being a family man", and "having financial independence". Socio-cultural factors, such as family environment, religion, public media and popular life style patterns helped to shape and reinforce the meanings of masculinities among university men. This study revealed that the university context provided a particular culture for construction and reinforcement of the meanings of masculinities, which should be considered by the educators to help in development of healthy masculinities.

  5. 'Learning to Wait’: Schooling and the Instability of Adulthood for Young Men in Uganda

    2016-01-01

    This chapter explores various perspectives on the shifting notion of adulthood in Uganda. Invoking Paul Willis’ book ‘Learning to Labour (2000 [1977]) concerning working class lads in Great Britain, we explore the implicit curriculum of how young men in Uganda learn to habituate the practice...... of waiting which is both characterised by creativity and passivity. Based on fieldwork in Kisoro and Tororo, we argue that young men learn to habituate the practice of waiting through schooling which leads them toward a kind of educated, docile but often frustrated and unstable adulthood. A growing body...... of literature around the globe has focused on how youth feel trapped in endless liminality without being able to achieve the assumed permanence of adulthood. However, male adulthood in rural Uganda is far from stable, as the position can easily be lost or gained. Adult status depends on several dimensions...

    The aim was to study associations of maximal strength and muscular endurance with inflammatory biomarkers independent of cardiorespiratory fitness in those with and without abdominal obesity. 686 young healthy men participated (25±5 years). Maximal strength was measured via isometric testing using dynamo-meters to determine maximal strength index. Muscular endurance index consisted of push-ups, sit-ups and repeated squats. An indirect cycle ergometer test until exhaustion was used to estimate maximal aerobic capacity (VO2max). Participants were stratified according to those with (>102 cm) and those without abdominal obesity (obesity (β=-0.08, -0.14, respectively) (pobesity (β=-0.11, -0.26, respectively) (p<0.05). This cross-sectional study demonstrated that muscular fitness is inversely associated with C-reactive protein and IL-6 concentrations in young adult men independent of cardiorespi-ratory fitness.

    This paper examines the drivers of male perpetration of violence against adult family members and intimate partners in Cape Town, South Africa. Data on 1,369 young men from the Cape Area Panel Study are analyzed and significant causal pathways are examined for the full sample and for disaggregated samples of African and coloured respondents. Socioeconomic disadvantage plays a role in a culture of patriarchal violence, but its effects are largely mediated by behavioural factors such as routine...

  8. Triceps surae contractile properties and firing rates in the soleus of young and old men.

    Mean maximal motor unit firing rates (MUFRs) of the human soleus are lower (5-20 Hz) than other limb muscles (20-50 Hz) during brief sustained contractions. With healthy adult aging, maximal MUFRs are 20-40% lower and twitch contractile speed of lower limb muscles are 10-40% slower compared with young adults. However, it is unknown whether the inherently low maximal MUFRs for the soleus are further reduced with aging in association with age-related slowing in contractile properties. The purpose of the present study was to compare the changes in triceps surae contractile properties and MUFRs of the soleus throughout a variety of contraction intensities in six old ( approximately 75 yr old) and six young ( approximately 24 yr old) men. Neuromuscular measures were collected from the soleus and triceps surae during repeated sessions (2-6 sessions). Populations of single MUFR trains were recorded from the soleus with tungsten microelectrodes during separate sustained 6- to 10-s isometric contractions of varying intensities [25%, 50%, 75%, and 100% maximal voluntary isometric contraction (MVC)]. The old men had weaker triceps surae strength (MVC; 35% lower) and slower contractile properties (contraction duration; 20% longer) than the young men. However, there was no difference in average MUFRs of the soleus at 75% and 100% MVC ( approximately 14.5 Hz and approximately 16.5 Hz, respectively). At 25% and 50% MVC, average rates were 10% and 20% lower in the old men compared with young, respectively. Despite a significant slowing in triceps surae contraction duration, there was no age-related change in MUFRs recorded at high contractile intensities in the soleus. Thus the relationship between the whole muscle contractile properties and MUFRs found in other muscle groups may not exist between the triceps surae and soleus and may be muscle dependent.

    High crime rates among second-generation immigrants are usually attributed to the ethnic group’s weak socioeconomic position in the host society. The causes of crime can, however, also be sought in their native countries or regions. Owing to a lack of empirical data, this has rarely been tested. The Netherlands is an exception: small-scale ethnographic case studies among young Moroccan men in Dutch cities suggest that their regional background and culture, particularly if they are from the le...

    We compared quantitative diary data with retrospective survey data collected from a cohort of young adult men who have sex with men (MSM) in Seattle, Washington. Ninety-five MSM, aged 16-30 years, completed web-based surveys every 3 months and were randomized to 4 diary submission schedules: every 2 weeks, once a week, twice a week, or never. We calculated diary completion rates and assessed agreement between daily diary data and aggregate retrospective survey data for sexual behavior measures. Over 6 months, 78 % of participants completed at least 80 % of their diary days, and the 2-week schedule had the highest and most consistent completion rate. The majority of sexual behavior and substance use measures had strong agreement between the diary and retrospective survey data (i.e., kappa >0.80 or concordance correlation coefficient ≥0.75), although we observed poorer agreement for some measures of numbers of anal sex acts. There were no significant differences in mean responses across diary schedules. We observed some evidence of reactivity (i.e., a difference in behavior associated with diary completion). Participants not assigned diaries reported significantly more unprotected anal sex acts and were more likely to be newly diagnosed with HIV or another sexually transmitted infection compared to those assigned active diary schedules. This study suggests that sexual behavior data collected from young adult MSM during 3-month retrospective survey--an interval commonly used in sexual behavior research--are likely valid. Diaries, however, may have greater utility in sexual behavioral research in which counts, timing, sequence, or within-person variation over time are of particular import.

    Serum lipid profiles of 76 men of young age (17-21years) were investigated using thin layer chromatography and determination of somatotypes was realized using the scheme of V.P. Chtetsov et al. (1978). The investigation was conducted on an empty stomach and after one hour after food loads (test meal with energy value of 419 kcal, content of proteins - 17,9 g, fats - 11,9 g, carbohydrates - 60,1 g). Regularities inherent to certain somatotypes were revealed. In young men with the abdominal somatotype (with the most pronounced fat component), changes evidencing membranes rigidity growth were revealed: cholesterol esterification processes inhibition and increase of sphingomyelin after meal (p = 0.001). In young men with muscular somatotype the highest level of phosphatidylcholine and the lowest level of easily-oxidized phospholipid fractions in comparison to other somatotypes [thoracic (p = 0.044), abdominal (p = 0.037) and undetermined (p = 0.021)] were registered. General rule is lowering of the free fatty acids levels after meal in comparison with the indices on the empty stomach for all somatotypes: thoracic (p = 0.0001), muscular (p = 0.012), abdominal (p = 0.041) and undetermined (p = 000018). Definiteness of the effect of lowering of free fatty acids levels after meal for all somatotypes could evidence the importance Of this process for maintaining the homeostatic body constants.

    The Girl Summit held in 2014 aimed to mobilise greater effort to end Female Genital Mutilation (FGM) within a generation, building on a global movement which viewed the practice as a severe form of violence against women and girls and a violation of their rights. The UN, among others, endorse "comprehensive" strategies to end FGM, including legalistic measures, social protection and social communications. FGM is a sensitive issue and difficult to research, and rapid ethnographic methods can use existing relations of trust within social networks to explore attitudes towards predominant social norms which posit FGM as a social necessity. This study used Participatory Ethnographic Evaluation Research (PEER) to understand young men's (18-25 years) perceptions of FGM, demand for FGM among future spouses, and perceptions of efforts to end FGM in a small town in West Pokot, Kenya, where FGM is reported to be high (between 85% to 96%). Twelve PEER researchers were recruited, who conducted two interviews with their friends, generating a total of 72 narrative interviews. The majority of young men who viewed themselves as having a "modern" outlook and with aspirations to marry "educated" women were more likely not to support FGM. Our findings show that young men viewed themselves as valuable allies in ending FGM, but that voicing their opposition to the practice was often difficult. More efforts are needed by multi-stakeholders - campaigners, government and local leaders - to create an enabling environment to voice that opposition.

    The aim of this study was to determine the average penile length of a group of healthy, young Turkish men, and to investigate the relationship between penile length and somatometric parameters in the same group. The flaccid and stretched length and circumference of the penis was measured in a group of 2276 physically normal, young men. The correlation between penile length and weight, height and body mass index (BMI) of the participants was determined by Pearson's analysis. The mean age of the participants was 21.1 ± 3.1 (18-39) years. The mean flaccid, fully stretched and circumferential length of the participants' penises were 8.95 ± 1.04, 13.98 ± 1.58 and 8.89 ± 0.86 cm, respectively. There was a significant relationship between all of these variables (Psizes and to make convenient decisions in the counseling and/or treatment of people with short penis concerns.

    Despite the popularity of dietary nitrate supplementation and the growing evidence base of its potential ergogenic and vascular health benefits, there is no direct information about its effects on exercising limb blood flow in humans. We hypothesized that acute dietary nitrate supplementation from beetroot juice would augment the increases in forearm blood flow, as well as the progressive dilation of the brachial artery, during graded handgrip exercise in healthy young men. In a randomized, double-blind, placebo-controlled crossover study, 12 young (22 ± 2 years) healthy men consumed a beetroot juice (140 mL Beet-It Sport, James White Juice Company) that provided 12.9 mmol (0.8 g) of nitrate or placebo (nitrate-depleted Beet-It Sport) on 2 study visits. At 3 h postconsumption, brachial artery diameter, flow, and blood velocity were measured (Doppler ultrasound) at rest and during 6 exercise intensities. Nitrate supplementation raised plasma nitrate (19.5-fold) and nitrite (1.6-fold) concentrations, and lowered resting arterial pulse wave velocity (PWV) versus placebo (all p nitrate supplementation had no effect on brachial artery diameter, flow, or shear rates at rest (all p ≥ 0.28) or during any exercise workload (all p ≥ 0.18). These findings suggest that acute dietary nitrate supplementation favorably modifies arterial PWV, but does not augment blood flow or brachial artery vasodilation during nonfatiguing forearm exercise in healthy young men.

    Black and Latino young men who have sex with men (YMSM) are at disproportionate risk for sexually transmitted diseases (STDs), including HIV. This study informs school-centered strategies for connecting YMSM to health services by describing their willingness, perceived safety, and experiences in talking to school staff about sexual health. Cross-sectional data were collected from Black and Latino YMSM aged 13-19 through web-based questionnaires (N = 415) and interviews (N = 32). School nurses were the staff members youth most often reported willingness to talk to about HIV testing (37.8%), STD testing (37.1%), or condoms (37.3%), but least often reported as safe to talk to about attraction to other guys (11.4%). Interviews revealed youth reluctance to talk with school staff including nurses when uncertain of staff members' perceptions of lesbian, gay, bisexual, transgender, and questioning (LGBTQ) people or perceiving staff to lack knowledge of LGBTQ issues, communities, or resources. Nurses may need additional training to effectively reach Black and Latino YMSM.

    An emerging body of evidence suggests that intergenerational sexual partnerships may increase risk of HIV acquisition among young men who have sex with men (YMSM). However, no studies have comprehensively evaluated literature in this area. We applied a scoping review methodology to explore the relationships between age mixing, HIV risk behavior, and HIV seroconversion among YMSM. This study identified several individual, micro-, and meso-system factors influencing HIV risk among YMSM in the context of intergenerational relationships: childhood maltreatment, coming of age and sexual identity, and substance use (individual-level factors); family and social support, partner characteristics, intimate partner violence, connectedness to gay community (micro-system factors); and race/ethnicity, economic disparity, and use of the Internet (meso-system factors). These thematic groups can be used to frame future research on the role of age-discrepant relationships on HIV risk among YMSM, and to enhance public health HIV education and prevention strategies targeting this vulnerable population.

    Young Black men who have sex with men (YBMSM) are often underrepresented in sexual health research because of concerns about safety, privacy, and the potential for research harms. Empirical data are needed to understand YBMSM experience of participating in research, benefits and harms (discomfort), to inform policy and regulatory decisions. Using qualitative methods, this article examines 50 YBMSM, aged 15-19 years, experiences of benefits/harms, challenges of participating in sexual health research, and contextual factors impacting research experiences. Participants were asked about benefits and harms experienced in answering questions about sexual orientation, first same-sex attraction, and same-sex sexual experiences after completing an in-depth interview. Interviews were transcribed and coded. Inductive open coding was used to identify themes within and between interviews. Participants were able to describe perceived direct benefits resulting from research interview participation, including awareness of risky sexual behaviors, a safe space to share early coming out stories and same-sex sexual experiences, and a sense of empowerment and comfort with one's sexual orientation. Indirect benefits described by participants included perceptions of helping others and the larger gay community. Few participants described harms (discomfort recalling experiences). Our data suggest that participating in qualitative sexual health research focused on sexual orientation, sexual attraction, and early same-sex sexual experiences may result in minimal harms for YBMSM and multiple benefits, including feeling more comfortable than in a general medical visit.

    Parental monitoring and parent-adolescent communication about sex protect against HIV-related sexual risk behaviors among heterosexual adolescents, but it is unknown if these findings generalize to young men who have sex with men (YMSM). Sexual orientation-specific stressors, including "coming out" to parents, complicate the family context of YMSM. We examined associations between parental monitoring, communication about sex, outness to cohabitating parents, and sexual behaviors. Ethnically diverse YMSM ages 14-19 provided cross-sectional data (n = 257). Monitoring and outness to parents interacted to predict recent same-sex unprotected anal intercourse (UAI). For YMSM who reported mixed or uncertain outness to parents, higher levels of perceived parental monitoring were associated with greater risk of UAI. Higher levels of communication about sex were associated with greater risk of UAI for YMSM out to parents. Parental monitoring and communication about sex might not protect YMSM against sexual risk in the same way they protect heterosexual youth. Future research should examine whether adapted forms of family factors could protect YMSM, and family-based HIV risk-reduction interventions for YMSM should be attuned to the unique ways family factors function within this group.

    There are few published estimates of anal human papillomavirus (HPV) infection rates among young men who have sex with men (YMSM). We estimated incidence and prevalence of type-specific anal HPV infection using clinician-collected anal swabs for HPV DNA testing obtained during a 1-year prospective study of 94 YMSM (mean age, 21 years) in Seattle. Seventy percent of YMSM had any HPV infection detected during the study, and HPV-16 and/or -18 were detected in 37%. The incidence rate for any new HPV infection was 38.5 per 1000 person-months and 15.3 per 1000 person-months for HPV-16/18; 19% had persistent HPV-16/18 infection. No participant tested positive for all 4 HPV types in the quadrivalent vaccine. The number of lifetime male receptive anal sex partners was significantly associated with HPV infection. The prevalence of HPV-16/18 was 6% among YMSM with a history of 1 receptive anal sex partner and 31% among YMSM with ≥ 2 partners. Although the high prevalence of HPV among YMSM highlights the desirability of vaccinating all boys as a strategy to avert the morbidity of HPV infection, most YMSM appear to remain naive to either HPV-16 or -18 well into their sexual lives and would benefit from HPV immunization.

    The present study aimed to determine whether the experience of bias-motivated bullying was associated with behaviors known to increase the risk of HIV infection among young men who have sex with men (YMSM) aged 18-29, and to assess whether the psychosocial problems moderated this relationship. Using an Internet-based direct marketing approach in sampling, we recruited 545 YMSM residing in the USA to complete an online questionnaire. Multiple linear regression analyses tested three regression models where we controlled for sociodemographics. The first model indicated that bullying during high school was associated with unprotected receptive anal intercourse within the past 12 months, while the second model indicated that bullying after high school was associated with engaging in anal intercourse while under the influence of drugs or alcohol in the past 12 months. In the final regression model, our composite measure of HIV risk behavior was found to be associated with lifetime verbal harassment. None of the psychosocial problems measured in this study - depression, low self-esteem, and internalized homonegativity - moderated any of the associations between bias-motivated bullying victimization and HIV risk behaviors in our regression models. Still, these findings provide novel evidence that bullying prevention programs in schools and communities should be included in comprehensive approaches to HIV prevention among YMSM.

    Culturally relevant prevention programs are required to reduce HIV risk exposure of Latino young men who have sex with men (YMSM). As part of Hermanos Jóvenes, 465 Latino YMSM were surveyed at community venues of New York City outside the gay-identified area of lower Manhattan. We examined factors that influence ethnic and gay community attachments; the association between community attachments and social support in sexual matters; and the relationship between levels of attachment, social support in sexual matters, and sexual risk behaviors. Sixty-eight percent felt closely connected to their ethnic community; about 34% were highly attached to both neighborhood and New York City gay communities. Greater social support in sexual matters was associated with ethnic and gay community attachments. Latino YMSM connected to their ethnic community were about 40% less likely to report recent unprotected anal intercourse (UAI) with a male partner, and 60% less likely to have engaged in UAI during the last sexual contact with a nonmain male partner. Gay community attachment was not significantly related to risk behaviors. Findings point to the importance of ethnic ties and involving ethnic community organizations in HIV prevention efforts.

    Few data exist on the early sexual behavior patterns of contemporary young men who have sex with men (YMSM), the social context of these patterns, and which of these factors influence risk for HIV and other sexually transmitted infections (STI). We enrolled 94 YMSM (age 16-30) into a 1-year cohort study with serial online retrospective surveys and HIV/STI testing. The first three partnerships of YMSM were characterized by relatively high rates of unprotected anal sex and a rapidly expanding sexual repertoire, but also increasing rates of HIV status disclosure. During follow-up, 17 % of YMSM reported any nonconcordant unprotected anal intercourse (NCUAI) and 15 % were newly diagnosed with HIV/STI. Sex education in high school and current maternal support were protective against HIV/STI, while isolation from family and friends was associated with recent NCUAI. Social support-including from parents, peers, and school-based sex education-may help mitigate HIV/STI risk in this population.

    The current study examined how impulsivity-related traits (negative urgency, sensation seeking, and positive urgency), behavioral measures of risk taking and reward seeking, and physiological reactivity related to three different risky sexual behaviors in sexually active undergraduate men (N = 135). Regression analyses indicated that sensation seeking and behavioral risk-taking predicted unique variance in number of sexual partners. These findings suggest that, for young men, acquisition of new partners is associated with need for excitement and reward and willingness to take risks to meet those needs. Sensation seeking, behavioral risk-taking, and skin conductance reactivity to arousing stimuli was related to ever having engaged in sex with a stranger, indicating that, for men, willingness to have sex with a stranger is related not only to the need for excitement and risk-taking but also with innate responsiveness to arousing environmental triggers. In contrast, regression analyses indicated that young men who were impulsive in the context of negative emotions were less likely to use condoms, suggesting that emotion-based impulsivity may be an important factor in negligent prophylactic use. This study adds to the current understanding of the divergence between the correlates of risky sexual behaviors and may lend utility to the development of individualized HIV prevention programming.

    Full Text Available OBJECTIVE: The present study aimed to measure the prevalence of adult attention deficit hyperactivity disorder (ADHD in a large, representative sample of young Swiss men and to assess factors associated with this disorder. METHODS: Our sample consisted of 5656 Swiss men (mean age 20 years who participated in the Cohort Study on Substance Use Risk Factors (C-SURF. ADHD was assessed with the World Health Organization (WHO adult ADHD Self Report Screener (ASRS. Logistic regression analyses were conducted to assess the association between ADHD and several socio-demographic, clinical and familial factors. RESULTS: The prevalence of ADHD was 4.0%, being higher in older and French-speaking conscripts. A higher prevalence also was identified among men whose mothers had completed primary or high school/university and those with a family history of alcohol or psychiatric problems. Additionally, adults with ADHD demonstrated impairment in their professional life, as well as considerable mental health impairment. CONCLUSION: Our results demonstrate that ADHD is common among young Swiss men. The impairments in function and mental health we observed highlight the need for further support and interventions to reduce burden in affected individuals. Interventions that incorporate the whole family also seem crucial.

    Full Text Available Abstract Background Many visitors, including military troops, who enter highland regions from low altitude areas may suffer from acute mountain sickness (AMS, which negatively impacts workable man-hours and increases healthcare costs. The aim of this study was to evaluate the population level risk factors and build a multivariate model, which might be applicable to reduce the effects of AMS on Chinese young men traveling to this region. Methods Chinese highland military medical records were used to obtain data of young men (n = 3727 who entered the Tibet plateau between the years of 2006-2009. The relationship between AMS and travel profile, demographic characteristics, and health behaviors were evaluated by logistic regression. Univariate logistic models estimated the crude odds ratio. The variables that showed significance in the univariate model were included in a multivariate model to derive adjusted odds ratios and build the final model. Data corresponding to odd and even years (2 subsets were analyzed separately and used in a simple cross-validation. Results Univariate analysis indicated that travel profile, prophylactic use, ethnicity, and province of birth were all associated with AMS in both subsets. In multivariate analysis, young men who traveled from lower altitude (600-800 m vs. 1300-1500 m, adjusted odds ratio (AOR = 1.32-1.44 to higher altitudes (4100-4300 m vs. 2900-3100 m, AOR = 3.94-4.12; 3600-3700 m vs. 2900-3100 m, AOR = 2.71-2.74 by air or rapid land transport for emergency mission deployment (emergency land deployment vs. normal land deployment, AOR = 2.08-2.11; normal air deployment vs. normal land deployment, AOR = 2.00-2.20; emergency air deployment vs. normal land deployment, AOR = 2.40-3.34 during the cold season (cold vs. warm, AOR = 1.25-1.28 are at great risk for developing AMS.

    We tested the hypothesis that women exhibit greater vasodilator responses to β-adrenoceptor stimulation compared with men. We further hypothesized women exhibit a greater contribution of nitric oxide synthase and cyclooxygenase to β-adrenergic-mediated vasodilation compared with men. Forearm blood flow (Doppler ultrasound) was measured in young men (n = 29, 26 ± 1 yr) and women (n = 33, 25 ± 1 yr) during intra-arterial infusion of isoproterenol (β-adrenergic agonist). In subset of subjects, isoproterenol responses were examined before and after local inhibition of nitric oxide synthase [N(G)-monomethyl-l-arginine (l-NMMA); 6 male/10 female] and/or cyclooxygenase (ketorolac; 5 male/5 female). Vascular conductance (blood flow ÷ mean arterial pressure) was calculated to assess vasodilation. Vascular conductance increased with isoproterenol infusion (P 0.99) or women (P = 0.21). In contrast, ketorolac infusion markedly increased isoproterenol-mediated responses in both men (P vasodilation is not different between men and women and sex differences in the independent contribution of nitric oxide synthase and cyclooxygenase to β-mediated vasodilation are not present. However, these data are the first to demonstrate β-adrenoceptor activation of cyclooxygenase suppresses nitric oxide synthase signaling in human forearm microcirculation and may have important implications for neurovascular control in both health and disease.

    Full Text Available Knowledge regarding the heterogeneity of BMI trajectories is limited for the Canadian population. Using latent class growth modelling, four distinct BMI trajectories of individuals from young adulthood to middle age were identified for both women and men from the longitudinal data of the National Population Health Survey. The associations between BMI trajectories and the individuals’ sociodemographic characteristics and behavioural factors were also examined. Aboriginal women were found more likely to be in the long-term overweight or obese groups. It reveals that increased years of smoking, drinking, and being physically active were associated with lowering the BMI trajectory in all groups for both women and men, with some exceptions in the long-term normal weight group for men. Increased years of rural living, being employed, and living with low income were associated with raising the BMI trajectory in all groups for women and in some groups for men. Food insecurity was associated with raising the BMI trajectory in each group for both women and men.

    The potential for young men in crisis to be supported by their lay networks is an important issue for suicide prevention, due to the under-utilisation of healthcare services by this population. Central to the provision of lay support is the capability of social networks to recognise and respond effectively to young men\\'s psychological distress and suicide risk. The aim of this qualitative study was to explore young men\\'s narratives of peer suicide, in order to identify how they interpreted and responded to behavioural changes and indications of distress from their friend before suicide. In-depth qualitative interviews were conducted during 2009\\/10 with 15 Irish males (aged 19-30 years) who had experienced the death by suicide of a male friend in the preceding 5 years. The data were analysed using a thematic approach. Through the analysis of the participants\\' stories and experiences, we identified several features of young male friendships and social interactions that could be addressed to strengthen the support available to young men in crisis. These included the reluctance of young men to discuss emotional or personal issues within male friendships; the tendency to reveal worries and emotion only within the context of alcohol consumption; the tendency of friends to respond in a dismissive or disapproving way to communication of suicidal thoughts; the difficulty of knowing how to interpret a friend\\'s inconsistent or ambiguous behaviour prior to suicide; and beliefs about the sort of person who takes their own life. Community-based suicide prevention initiatives must enhance the potential of young male social networks to support young men in crisis, through specific provisions for developing openness in communication and responsiveness, and improved education about suicide risk.

    The purpose of this study was to compare the effects of a bout of high-volume isokinetic resistance exercise (HVP) on lower-body strength and markers of inflammation and muscle damage during recovery between young and middle-aged men. Nineteen recreationally-trained men were classified as either a young adult (YA: 21.8 ± 2.0 y; 90.7 ± 11.6 kg) or middle-aged adult (MA: 47.0 ± 4.4 y; 96.0 ± 21.5 kg) group. The HVP consisted of 8 sets of 10 repetitions, with one minute of rest between each set, performed on an isokinetic dynamometer at 60°·sec. Maximal voluntary isometric contractions (MVIC) and isokinetic peak (PKT) and average (AVGT) torque (measured at 240° and 60°·sec) were assessed at baseline (BL), immediately-post (IP), 120-min (120P), 24-hr (24H) and 48-hr (48H) following HVP. Blood was obtained at BL, IP, 30-min, 60-min, 120-min, 24H and 48H following HVP to assess muscle damage and inflammation. All performance data were analyzed using repeated-measures ANCOVA, while all inflammatory and muscle damage markers were analyzed using a two-way (time x group) repeated-measures ANOVA. Results revealed no between-group differences for PKT, AVGT, or rate of torque development at 200ms (RTD200). No between-group differences in myoglobin, creatine kinase, C-reactive protein, or interleukin-6 were observed. Although baseline differences in muscle performance were observed between YA and MA, no between group differences were noted in performance recovery measures from high-volume isokinetic exercise in recreationally-trained men. These results also indicate that the inflammatory and muscle damage response from high-volume isokinetic exercise is similar between recreationally-trained, young and middle-aged adult men.

    Objective Doubly labeled water (DLW) method is the gold standard for measuring total energy expenditure (TEE). We used this method to measure TEE in Chinese young men. Methods Sixteen healthy young men age 23±1 years with body mass index 22.0±1.4 kg/m2 were recruited. TEE was measured by the DLW method, and basal energy expenditure (BEE) was determined by indirect calorimetry. We also conducted 24-h activity, energy balance and factorial approach to estimate energy requirements of the subjects. Results TEE of subjects by DLW method was 9.45±0.57 MJ/day (2258±180 kcal/day). The 24-h activity was 10.80±0.33 MJ/day (2582±136 kcal/day). The energy requirement, derived from energy balance observations, was 9.93±1.32 MJ/day (2373±315 kcal/day). The BEE of 6.65±0.28 MJ/day (1589±67 kcal/day), calculated by the adjusted Schofield equation, was significantly higher (P<0.001) than that measured by indirect calorimetry, 5.99±0.66 MJ/day (1433±158 kcal/day). The TEE derived from the factorial approach was 10.31±0.43 MJ/day (2463±104 kcal/day). Conclusion The TEE of Chinese young men measured by the DLW method was about 10%lower than the current recommended nutrient intake (RNI), suggesting that the RNI for Chinese men maybe overestimated. Further studies are warranted to determine the value of the estimated energy requirement.

    Full Text Available BACKGROUND: To determine whether androgen receptor (AR CAG (polyglutamine and GGN (polyglycine polymorphisms influence bone mineral density (BMD, osteocalcin and free serum testosterone concentration in young men. METHODOLOGY/PRINCIPAL FINDINGS: Whole body, lumbar spine and femoral bone mineral content (BMC and BMD, Dual X-ray Absorptiometry (DXA, AR repeat polymorphisms (PCR, osteocalcin and free testosterone (ELISA were determined in 282 healthy men (28.6+/-7.6 years. Individuals were grouped as CAG short (CAG(S if harboring repeat lengths of 21, and GGN was considered short (GGN(S or long (GGN(L if GGN 23. There was an inverse association between logarithm of CAG and GGN length and Ward's Triangle BMC (r = -0.15 and -0.15, P<0.05, age and height adjusted. No associations between CAG or GGN repeat length and regional BMC or BMD were observed after adjusting for age. Whole body and regional BMC and BMD values were similar in men harboring CAG(S, CAG(L, GGN(S or GGN(L AR repeat polymorphisms. Men harboring the combination CAG(L+GGN(L had 6.3 and 4.4% higher lumbar spine BMC and BMD than men with the haplotype CAG(S+GGN(S (both P<0.05. Femoral neck BMD was 4.8% higher in the CAG(S+GGN(S compared with the CAG(L+GGN(S men (P<0.05. CAG(S, CAG(L, GGN(S, GGN(L men had similar osteocalcin concentration as well as the four CAG-GGN haplotypes studied. CONCLUSION: AR polymorphisms have an influence on BMC and BMD in healthy adult humans, which cannot be explained through effects in osteoblastic activity.

    Objectives. We examined associations of individual, psychosocial, and social factors with unprotected anal intercourse (UAI) among young men who have sex with men in New York City. Methods. Using baseline assessment data from 592 young men who have sex with men participating in an ongoing prospective cohort study, we conducted multivariable logistic regression analyses to examine the associations between covariates and likelihood of recently engaging in UAI with same-sex partners. Results. Nineteen percent reported recent UAI with a same-sex partner. In multivariable models, being in a current relationship with another man (adjusted odds ratio [AOR] = 4.87), an arrest history (AOR = 2.01), greater residential instability (AOR = 1.75), and unstable housing or homelessness (AOR = 3.10) was associated with recent UAI. Although high levels of gay community affinity and low internalized homophobia were associated with engaging in UAI in bivariate analyses, these associations did not persist in multivariable analyses. Conclusions. Associations of psychosocial and socially produced conditions with UAI among a new generation of young men who have sex with men warrant that HIV prevention programs and policies address structural factors that predispose sexual risk behaviors.

    The purpose of this study was to determine whether the loss of muscle strength in the elderly could be explained entirely by a decline in the physiological cross-sectional area (PCSA) of muscle. Isometric force, muscle activation (twitch interpolation), and coactivation (surface electromyograph) were measured during maximal voluntary contractions (MVCs) of the elbow flexors (EFs) and extensors (EEs) in 20 young (23 +/- 3 yr) and 13 older (81 +/- 6 yr) healthy men. PCSA was determined using magnetic resonance imaging, and normalized force (NF) was calculated as the MVC/PCSA ratio. The PCSA was smaller in the old compared with the young men, more so in the EEs (28%) compared with the EFs (19%) (P MVC (approximately 30%) with age was similar in the two muscle groups. Muscle activation was not different between the groups, but coactivation was greater (5%) (P architecture of the triceps brachii muscle. In conclusion, although the decline in PCSA explained the majority of strength loss in the old men, additional factors such as greater coactivation or reduced specific tension also may have contributed to the age-related loss of isometric strength.

    Our objectives were to: (1) compare multiple measures of partnership concurrency, including the UNAIDS-recommended definition and (2) describe the prevalence and correlates of concurrent sexual partnerships among young Kenyan men. We analyzed 10,907 lifetime partnerships of 1,368 men ages 18-24 years enrolled in a randomized trial of male circumcision to reduce HIV-1 incidence in Kisumu. Partnership concurrency was determined by overlapping dates and examined over varying recall periods and assumptions. The lifetime prevalence of concurrency was 77 %. Sixty-one percent of all partnerships were concurrent and factors associated with concurrency differed by partner type. Point prevalence of concurrency at the time of the interview was consistently the highest and UNAIDS-recommended definition was the most conservative (25 vs. 18 % at baseline, respectively). Estimates of concurrency were influenced by methods for definition and measurement. Regardless of definition, concurrent partnerships are frequent in this population of young, sexually active men in high HIV prevalence Kisumu, Kenya.

    The objective of this study was to evaluate the effects of a high dose of alcohol on physiological and psychological parameters in young men and women with a previous history of alcohol consumption. Systolic and diastolic blood pressure, heart rate, state anxiety, attention, time estimation and manual dexterity were registered before (phase 1) and after (phase 2) intake of alcohol (38.4 g) or a non-alcoholic beverage. Trait anxiety was registered in phase 2 only. The results showed that acute consumption of a high dose of alcohol: i) improves attention in men (although the performance of alcohol consumers was not better than that of non-consumers); ii) blocks the systolic blood pressure habituation phenomenon (observed in controls) in women; and iii) blocks the improvement in manual dexterity (associated with experience in non-consumers) in both sexes. On the other hand, male consumers had a lower heart rate than non-consumers, independently of the phase, while female consumers had a higher state anxiety and performed worse in attention than controls, also independently of the phase. These results help to understand the extent of performance impairment of different tasks produced by risk alcohol consumption in young men and women.

    Interpersonal sensitivity is characterized by the predisposition to perceive and elicit criticism, rejection, and negative social evaluation. It may be linked to poorer physical or functional health outcomes, particularly in the interpersonal context (cancer-related sexual dysfunction). This study tested the association of interpersonal sensitivity with sexual functioning following testicular cancer in young men and whether this association is moderated by coping processes. Men ages 18 to 29 (N = 171; M age = 25.2, SD = 3.32) with a history of testicular cancer were recruited via the California State Cancer Registry and completed questionnaire measures including assessments of interpersonal sensitivity, sexual functioning, and approach and avoidance coping. Regression analysis controlling for education, age, partner status, ethnic status, and time since diagnosis revealed that higher interpersonal sensitivity was significantly related to lower sexual functioning (β = -0.18, p Cancer-related approach-oriented coping was associated with better sexual functioning (β = 0.19, p testicular cancer. Enhancement of coping skills may be a useful direction for intervention development for interpersonally sensitive young men with cancer.

    Full Text Available Abstract Background Currently, there is insufficient evidence available regarding the relationship between level of physical fitness and health-related quality of life (HRQoL in younger adults. Therefore, the aim of the present study was to investigate the impact of measured cardiovascular and musculoskeletal physical fitness level on HRQoL in Finnish young men. Methods In a cross-sectional study, we collected data regarding the physical fitness index, including aerobic endurance and muscle fitness, leisure-time physical activity (LTPA, body composition, health, and HRQoL (RAND 36 for 727 men [mean (SD age 25 (5 years]. Associations between HRQoL and the explanatory parameters were analyzed using the logistic regression analysis model. Results Of the 727 participants who took part in the study, 45% were in the poor category of the physical fitness, while 37% and 18% were in the satisfactory and good fitness categories, respectively. A higher frequency of LTPA was associated with higher fitness (p Conclusions Our study of Finnish young men indicates that higher physical fitness and leisure-time physical activity level promotes certain dimensions of HRQoL, while morbidities impair them all. The results highlight the importance of health related physical fitness while promoting HRQoL.

    Spirituality and religiosity may serve as both a resource and a barrier to HIV prevention with young black men who have sex with men (YBMSM). We examined indices of spirituality/religiosity as correlates of binge drinking, stimulant use, and recent HIV testing in a sample of YBMSM. From 2011-2013, annual venue-based surveys of sexually active YBMSM ages 18-29 were conducted in Dallas and Houston, Texas. Binge drinking and stimulant use were assessed in the past two months. Participants recently tested for HIV (i.e., within the past six months) were compared to those without recent HIV testing (i.e., never tested or tested more than six months ago). Among the 1565 HIV-negative or HIV-unknown YBMSM enrolled, more engagement in spiritual and religious activities was associated with greater odds of reporting stimulant use (Adjusted Odds Ratio [AOR]=1.20; 95% CI=1.04-1.40) while higher spiritual coping was associated with lower odds of reporting stimulant use (AOR=0.66; 95% CI=0.56-0.78). Binge drinking was independently associated with 29% lower odds of recent HIV testing (AOR=0.71; 95% CI=0.55-0.92), but lower odds of binge drinking did not mediate the association of engagement in spiritual and religious activities with 27% greater odds of recent HIV testing (AOR=1.27; 95% CI=1.11-1.46). Among YBMSM, culturally tailored approaches addressing spirituality/religiosity could support prevention of stimulant use and increase HIV testing. In particular, expanded efforts are needed to promote HIV testing in binge drinkers. Copyright © 2017 Elsevier B.V. All rights reserved.

    Evidence suggests that respondent-driven sampling (RDS) is an efficient approach to sampling among varied populations of adult men who have sex with men (MSM) both in the USA and abroad, although no studies have yet evaluated its performance among younger MSM, a population with a steep rise in HIV infection in recent years. Young MSM (YMSM) may differ in terms of their connectedness to other YMSM (e.g., due to evolving sexual identity, internalization of sexual minority stigma, and lack of disclosure to others) and mobility (e.g., due to parental monitoring) which may inhibit the sampling process. The aims of this study were to evaluate the efficiency and effectiveness of RDS-based sampling among young urban MSM and to identify factors associated with recruitment success. We hypothesized that demographic, social, behavioral, and network factors, including racial/ethnic minority status, homelessness (i.e., as an indicator of socioeconomic marginalization), HIV-positive status, substance use problems, gay community connectedness, and network size would be positively related to recruitment productivity, while sexual minority stigmatization, environmental barriers (e.g., parental monitoring), and meeting sex partners on the internet (i.e., virtual venue) would be negatively related to recruitment productivity. Between December 2009 and February 2013, we used RDS to recruit a sample of 450 YMSM, ages 16-20. Findings suggest that the use of RDS for sampling among YMSM is challenging and may not be feasible based on the slow pace of recruitment and low recruitment productivity. A large number of seeds (38 % of the sample, n = 172) had to be added to the sample to maintain a reasonable pace of recruitment, which makes use of the sample for RDS-based population estimates questionable. In addition, the prevalence of short recruitment chains and segmentation in patterns of recruitment by race/ethnicity further hamper the network recruitment process. Thus, RDS was not

    Full Text Available Percent body fat content was found in apparently normal healthy 30 young (17-20 Yrs. and 30 middle aged men (30-46 Yrs. by measuring the skinfold and girth. None of the subjects were athletes or did regular physical exercise. Body density was calculated using mean of the four skinfold measurements as per the equations advocated by Durnin and Womersley, while percent body fat content was calculated from the body density by the Siri′s equation. The mean % body fat content by this method in young men was 15.87 +/- 3.85% and in middle aged men was 24.75 +/- 3.55%. Ten percent of the young subjects and 90% of the middle aged subjects were found to be obese. Percent body fat content was also calculated from the girth measurements as advocated by McArdle et al. The mean of % body fat content with this method was 14.91 +/- 3.82% in young men and 24.30 +/- 3.35% in middle aged men. On comparison, the difference in percent body fat content calculated by both the methods was found to be significant in young men but not for middle aged men. The correlation, coefficient between girth method and skinfold method was 0.95 in case of young men and 0.90 for middle aged men. Therefore, we advocate that girth measurements can be used to determine percent body fat content, main advantage being simplicity of technique and requirement of inexpensive instruments for measurement.

    This mixed methods study used an explanatory sequential design to examine the relationship between attachment and sexual behavior among young Black gay and bisexual men (YBGBM). Cross sectional online surveys and sex diaries were completed by a sample of YBGBM in New York City (n = 153) to assess the association between adult attachment insecurity and sexual risk behavior. The Experiences in Close Relationships Scale-Revised (ECR-R) was used to assess three types of adult attachment (i.e., secure, anxious, and avoidant). Participants reported condomless sex encounters, as well as serodiscordant condomless anal sex encounters, as measures of sexual risk. Quantitative findings suggested that there were few associations between attachment type and sexual risk behavior; only men with attachment avoidance were likely to engage in condomless sex. However, qualitative findings illuminated some of the social complexities of the association between attachment in childhood, attachment in young adulthood and intimate partnerships, which could be linked to young adult sexual risk behavior. The study findings highlight the need for researchers to further examine the process by which individual differences in attachment orientation are related to YBGBM's sexual behavior.

    This study describes a community outreach project designed to increase access to reproductive health services to young African American men living in low-income urban neighborhoods. The project examined the effectiveness of providing community-based outreach and health education on increasing sexually transmitted disease (STD) screening. Outreach workers provided STD education and risk assessment in community settings, including street corners, parks, schools, and community centers. Data were recorded on outreach contacts, including client demographics, health education topics covered, and risk assessment results. Outreach workers conducted 9,701 contacts in a 176-week period. Most contacts (89%) were with African Americans, and most (84%) were with young men between 15 and 20 years old. Outreach workers discussed each health education item in their protocol at least 85% of the time and each risk assessment item at least 90% of the time. The majority of contacts (94%) reported being sexually active. Compared with the year prior to the project, actual STD testing of the target population doubled at the project clinics. This study suggests that going beyond traditional clinic-based testing to reach young, disenfranchised males constitutes a promising approach to reducing racial disparities in STD infections.

  12. DIGITAL MEDIA AS CLASSIFIED AND CLASSIFYING: THE CASE OF YOUNG MEN IN SWEDEN

    Full Text Available Digital media [1] are widely talked about as a democratising force. As internet access proliferates, it is implied, structural constraints will dissolve and bring greater equality - if not instantly, but gradually as today's youth, the digital generation, come of age and agents of the old, non-digital order pass away. Thus, the alleged boundlessness of digital media is thought of as somehow having unbound young people from the larger social structure of power relations. Drawing on the ideas of Pierre Bourdieu, the present article examines the significance of social class for the ways in which young Swedish men perceive, interpret and make use of digital media in their everyday lives. The results suggest that class, through the workings of habitus, shapes the young men's approaches to education, leisure and the future, which, in turn, tend to generate divergent readings of digital media. Those who are privileged in terms of cultural and economic capital think and make use of digital media in compliance with the perceived moral order of digital goods and practices as instituted and imposed by the educational system, for example, whereas those disprivileged in this respect, although recognising the dominant scheme of classification and valuation of such goods and practices, tend to use them in ways that are at odds with it, thereby contributing to the workings of symbolic violence, i.e. to their own subordination.

    Protein-rich supplements are used widely for the management of malnutrition in young and older people. Protein is the most satiating of the macronutrients in young. It is not known how the effects of oral protein ingestion on energy intake, appetite, and gastric emptying are modified by age. The aim of the study was to determine the suppression of energy intake by protein compared with control and underlying gastric-emptying and appetite responses of oral whey protein drinks in eight healthy older men (69-80 yr) compared with eight young male controls (18-34 yr). Subjects were studied on three occasions to determine the effects of protein loads of 30 g/120 kcal and 70 g/280 kcal compared with a flavored water control-drink (0 g whey protein) on energy intake (ad libitum buffet-style meal), and gastric emptying (three-dimensional-ultrasonography) and appetite (0-180 min) in a randomized, double-blind, cross-over design. Energy intake was suppressed by the protein compared with control (P = 0.034). Suppression of energy intake by protein was less in older men (1 ± 5%) than in young controls (15 ± 2%; P = 0.008). Cumulative energy intake (meal+drink) on the protein drink days compared with the control day increased more in older (18 ± 6%) men than young (1 ± 3%) controls (P = 0.008). Gastric emptying of all three drinks was slower in older men (50% gastric-emptying time: 68 ± 5 min) than young controls (36 ± 5 min; P = 0.007). Appetite decreased in young, while it increased in older (P protein-induced suppression of energy intake by whey protein compared with young controls, so that in the elderly men, protein ingestion increased overall energy intake more than in the young men.

    Gender, age, and culturally specific beliefs are often considered relevant to observed variation in social interactions. At present, however, the scientific literature is mixed with respect to the significance of these factors in guiding moral judgments. In this study, we explore the role of each of these factors in moral judgment by presenting the results of a web-based study of Eastern (i.e., Russia) and Western (i.e., USA, UK, Canada) subjects, male and female, and young and old. Participants (n = 659) responded to hypothetical moral scenarios describing situations where sacrificing one life resulted in saving five others. Though men and women from both types of cultures judged (1) harms caused by action as less permissible than harms caused by omission, (2) means-based harms as less permissible than side-effects, and (3) harms caused by contact as less permissible than by non-contact, men in both cultures delivered more utilitarian judgments (save the five, sacrifice one) than women. Moreover, men from Western cultures were more utilitarian than Russian men, with no differences observed for women. In both cultures, older participants delivered less utilitarian judgments than younger participants. These results suggest that certain core principles may mediate moral judgments across different societies, implying some degree of universality, while also allowing a limited range of variation due to sociocultural factors.

    To test the effects of media violence exposure on blood pressure, negative affect, hostile social information processing, uncooperative behavior, and attitudes toward health risk behaviors among young men varying in lifetime violence exposure within the home and community. Experimental laboratory study. University campus situated within an urban environment. One hundred male undergraduates aged 18 to 21 years. Men who had previously reported differing amounts of lifetime home and community violence were randomly assigned to play The Simpsons: Hit and Run (low-violence condition) or Grand Theft Auto III (high-violence condition). Systolic and diastolic blood pressure; negative affect; hostile social information processing; uncooperative behavior; and permissive attitudes toward violence, alcohol use, marijuana use, and sexual activity without condom use. Men randomly assigned to play Grand Theft Auto III exhibited greater increases in diastolic blood pressure from a baseline rest period to game play, greater negative affect, more permissive attitudes toward using alcohol and marijuana, and more uncooperative behavior in comparison with men randomly assigned to play The Simpsons. Only among participants with greater exposure to home and community violence, play of Grand Theft Auto III led to elevated systolic blood pressure in comparison with play of The Simpsons (mean, 13 vs 5 mm Hg). Media violence exposure may play a role in the development of negative attitudes and behaviors related to health. Although youth growing up in violent homes and communities may become more physiologically aroused by media violence exposure, all youth appear to be at risk for potentially negative outcomes.

  18. Perception of masculinity amongst young Malaysian men: a qualitative study of university students

    2013-01-01

    Background Perception of Masculinity plays an important role in men’s lifestyles and health behaviors. Although, the importance of masculinity has been widely discussed in men’s health literature, very little is known about the meanings of masculinity in the Malaysian setting. This research aimed to explore the meanings of masculinity among Malaysian university men. Methods This qualitative study utilized in-depth interviews with 34 young Malaysian university men, aged 20–30 years from three main ethnic groups in Malaysia (Malay, Chinese and Indian). Thematic analysis approach was used to extract data. NVIVO v8 qualitative software was used for data management. Results From the data collected several concepts emerged that reflected the meanings of masculinity from the participants’ view points. These meanings were associated with a combination of traditional and non-traditional norms that generally benefit men who behave according to culturally dominant role expectations. These included: “Having a good body shape”, “being respected”, “having success with women”, “being a family man”, and “having financial independence”. Socio-cultural factors, such as family environment, religion, public media and popular life style patterns helped to shape and reinforce the meanings of masculinities among university men. Conclusions This study revealed that the university context provided a particular culture for construction and reinforcement of the meanings of masculinities, which should be considered by the educators to help in development of healthy masculinities.

  2. Size Matters Stature Is Related to Diagnoses of Depression in Young Military Men

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Evolutionary theories suggest that depression has evolved as an adaptation to insurmountable adversity or defeat. One prediction stemming from these models is that individual attributes associated with defeat in a given social environment could be risk factors for depression. We hypothesized that in young military men, where physical prowess was important, short stature might constitute a risk of depression and that this risk would be specific to depression and not to other prevalent mental disorders such as anxiety. A preliminary analysis of the diagnostic profile of a sample of male military personnel treated for mental health indicates that men both shorter and taller than average by 1 standard deviation may be predisposed to higher rates of depressive but not anxiety disorders. Practical and theoretical implications of our findings are discussed.

  3. Unrequited Love among Young Filipino Gay Men: Subjective Experiences of Unreciprocated Lovers

    2011-06-01

    Full Text Available In this exploratory study, I investigated lived experiences of unrequited love among young Filipino gay men in order to explore unrequited love beyond its heteronormative forms. Analysis of qualitative accounts from 11 out gay men who participated in focus groups indicated that unrequited love was a highly meaningful subjective experience involving a spectrum of negative affect, uncertainty, and self-esteem lowering. Non-reciprocity was often attributed to a lack of matching on dimensions like availability, sexual orientation, relationship goals, and personality. Non-homophobic social support was important in the reduction of uncertainty and management of distress, in addition to other strategies for coping with rejection and non-formation of the desired love relationship.

    Measles remains a major public health concern in Thailand despite the introduction of vaccination since 1984. Similar to other countries, Thailand has experienced numerous measles outbreaks including adult communities such as university student dormitories, prisons, refugee camps, and military recruit camps. These outbreaks raise questions on the seroprotective antibody level in Thai adults. To better understand measles susceptibility in young Thai adults, a retrospective measles seroprevalence study on repository serum specimens obtained with informed consent from young Thai men entering the Royal Thai Army (RTA) during 2007-2008 was conducted. A total of 7760 stratified randomized samples were chosen by residence province. Measles IgG titer was measured using a commercial IgG quantitative ELISA kit following the manufacturer's instructions. An antibody level ≥ 250 International Units per Liter (IU/L) was interpreted as seropositive. The overall measles seroprevalence was 78.5 % (95 % Confidence Interval: 77.6-79.4 %) with geometric mean titer of 738 IU/L (95 % Confidence Interval: 716-760 IU/L). The measles seroprevalence by province ranged from 59.6 % to 93.1 %. A trend of decreasing seroprevalence in the younger cohorts despite increasing immunization coverage was found. Lower seroprevalence than vaccination coverage was observed in the youngest age group. To achieve long term measles control and elimination, an integrated two doses vaccination strategy has been implemented in children in Thailand. This nationwide measles seroprevalence study in young adult RTA recruits found a measles seroprevalence lower than WHO's recommendation for measles outbreak prevention and elimination. These results raise concerns for measles control in Thailand. Supplementary immunization in young adults is essential especially in high-risk and densely populated communities to establish herd immunity for outbreak prevention and elimination.

    Young men often define themselves and their masculine identity through romantic and sexual relationships, and their resulting sexual decisions can affect their successful transition into adulthood, as well as STI, HIV and pregnancy rates. This paper looks at how young Paraguayan men's peer groups, family and masculine identity formation influence their behaviours in sexual and romantic relationships. In Asunción, Paraguay, we conducted five focus-group discussions (FGDs) examining neighbourhood norms in 2010, with male peer groups ranging in age from 14 to 19 years. We then interviewed half the members from each peer group to examine their relationships with friends, family and young women and their beliefs about existing gender norms. Young men described two types of masculine norms, 'partner/provider' and macho, and two types of romantic relationships, 'casual' and 'formal'. The language used to describe each spectrum of behaviours was often concordant and highlights the connection between masculine norms and romantic relationships. The perceived norms for the neighbourhood were more macho than the young men's reported behaviours. Norms cannot change unless young men speak out about their non-normative behaviours. This provides evidence for more research on the formation, meaning and transformation of male gender norms.

    Remembering painful incidents has important adaptive value but may also contribute to clinical symptoms of posttraumatic stress disorder and chronic pain states. Because glucocorticoids are known to impair memory retrieval processes, we investigated whether cortisol affects recall of previously experienced pain in healthy young men. In a double-blind, placebo-controlled crossover study, 20 male participants were presented pictures, half of them combined with a heat-pain stimulus. The next day, the same pictures were shown in the absence of pain. Cortisol (20 mg) administered 1h before retention testing reduced recall of explicit contextual pain memory, whereas it did not affect pain threshold or pain tolerance.

    The potential for young men in crisis to be supported by their lay networks is an important issue for suicide prevention, due to the under-utilisation of healthcare services by this population. Central to the provision of lay support is the capability of social networks to recognise and respond effectively to young men's psychological distress and suicide risk. The aim of this qualitative study was to explore young men's narratives of peer suicide, in order to identify how they interpreted and responded to behavioural changes and indications of distress from their friend before suicide. In-depth qualitative interviews were conducted during 2009/10 with 15 Irish males (aged 19-30 years) who had experienced the death by suicide of a male friend in the preceding 5 years. The data were analysed using a thematic approach. Through the analysis of the participants' stories and experiences, we identified several features of young male friendships and social interactions that could be addressed to strengthen the support available to young men in crisis. These included the reluctance of young men to discuss emotional or personal issues within male friendships; the tendency to reveal worries and emotion only within the context of alcohol consumption; the tendency of friends to respond in a dismissive or disapproving way to communication of suicidal thoughts; the difficulty of knowing how to interpret a friend's inconsistent or ambiguous behaviour prior to suicide; and beliefs about the sort of person who takes their own life. Community-based suicide prevention initiatives must enhance the potential of young male social networks to support young men in crisis, through specific provisions for developing openness in communication and responsiveness, and improved education about suicide risk.

    The purpose of this study was to examine heart rate recovery (HRR) and linear/nonlinear heart rate variability (HRV) before and after resistance training. Fourteen young men (25.0 +/- 1.1 yr of age) completed a crossover design consisting of a 4-wk time-control period, 6 wk of resistance training (3 days/wk), and 4 wk of detraining. Linear HRV was spectrally decomposed using an autoregressive approach. Nonlinear dynamics of heart rate complexity included sample entropy (SampEn) and Lempel-Ziv entropy (LZEn). HRR was calculated from a graded maximal exercise test as maximal heart rate attained during the test minus heart rate at 1 min after exercise (HRR). There was no change in SampEn, LZEn, or HRR after the time-control portion of the study (P > 0.05). SampEn (P change in spectral measures of HRV at any time point (P > 0.05). These findings suggest that resistance exercise training increases heart rate complexity and HRR after exercise but has no effect on spectral measures of HRV in young healthy men. These autonomic changes regress shortly after cessation of training.

    Seminomas are very radiosensitive tumors. Therefore, patients with malignant spinal cord compression (MSCC) from seminoma may not require for neurosurgery in addition to radiotherapy. In this study, radiotherapy alone was evaluated in young men with MSCC from seminoma. Four young men with MSCC due to vertebral lesions from metastatic seminoma received radiotherapy alone. The impact of radiotherapy on motor function and gait function, local control of MSCC and survival were retrospectively evaluated. All patients showed improvement of motor function following irradiation. All patients who were not able to walk prior to radiotherapy regained their walking ability. One-year and two-year local control rates were 100% and 100%, respectively. Survival rates at one and two years were 75% and 75%, respectively. Radiotherapy alone resulted in excellent outcomes. If clear indications for neurosurgery are not given, radiotherapy alone can be considered the treatment of choice for patients with MSCC from seminoma.

    There is substantial knowledge about the inverse association of physical fitness and CVD risk factors and CVD mortality. However, physical fitness per se might be influenced by lifestyle conditions such as physical training, smoking and drinking habits. We evaluated the relationship between physical fitness, physical activity, endurance training, smoking and drinking habits and blood pressure, lipids and leukocytes as surrogate cardiovascular risk markers in a large-scale cross-sectional study of healthy young men. A total of 6748 healthy young men were selected during their primary flight medical examination for military flying duties. Physical fitness was assessed by achieved physical working capacity at a heart rate of 170 beats per min (PWC170) during cycle ergometry. Parameters such as physical activity, endurance sports, smoking of cigarettes and drinking of alcoholic beverages were assessed by means of standardized questionnaires. Systolic and diastolic blood pressures were measured manually. Fasting cholesterol and triglycerides as well as white blood counts were obtained. Physical activity itself was not related to significant differences in the tested variables, whereas good physical fitness showed a significant association with improved blood pressure and blood lipids (Pfitness is associated with improved blood pressure and blood lipids. This effect is independent of participating mainly in endurance or nonendurance sports, of physical activity per se, and it does not depend on smoking and drinking habits. Smoking itself revealed relevant higher inflammation independent of fitness.

    Free fatty acids (FFAs) affect anterior pituitary function. However, the effect of FFAs on corticotropin (ACTH) and cortisol in humans is controversial. Thus, we assessed the effect of a pronounced increase in circulating FFA levels induced by infusion of lipid/heparin on ACTH and cortisol secretion in young men. Eight healthy male volunteers who underwent a 10-hour overnight fast were investigated. A 20% lipid/heparin or saline/heparin infusion was given at a rate of 1.5 mL/min for 6 hours. A euglycemic hyperinsulinemic clamp was performed in 6 subjects 4 hours after the start of infusion. To assess steroid metabolism, we measured ACTH, cortisol, FFAs, and urinary steroids. Lipid infusion increased FFAs (6.06 +/- 0.52 vs 0.70 +/- 0.23 mmol/L; P < .005) and induced insulin resistance (glucose infusion rate, 4.08 +/- 2.15 vs 6.02 +/- 2.60 mg/kg per minute; P < .005). Serum cortisol and plasma ACTH decreased independent of lipid/heparin or saline/heparin infusion. In addition, we found no effect of hyperinsulinemia on ACTH and cortisol levels. There were no differences in urinary free cortisol, urinary free cortisone, 5beta-tetrahydrocortisol, 5alpha-tetrahydrocortisol, and tetrahydrocortisone. In conclusion, FFAs had no effect on basal ACTH and cortisol secretion in normal-weight young men. In addition, no alterations in urinary glucocorticoid metabolites were detected, suggesting unchanged cortisol metabolism during lipid infusion.

    Most research on child pornography use has been based on selected clinical or criminal justice samples; risk factors for child pornography use in the general population remain largely unexplored. In this study, we examined prevalence, risk factors, and correlates of viewing depictions of adult-child sex in a population-representative sample of 1,978 young Swedish men (17-20 years, Mdn = 18 years, overall response rate, 77 %). In an anonymous, school-based survey, participants self-reported sexual coercion experiences, attitudes and beliefs about sex, perceived peer attitudes, and sexual interests and behaviors; including pornography use, sexual interest in children, and sexually coercive behavior. A total of 84 (4.2 %) young men reported they had ever viewed child pornography. Most theory-based variables were moderately and significantly associated with child pornography viewing and were consistent with models of sexual offending implicating both antisociality and sexual deviance. In multivariate logistic regression analysis, 7 of 15 tested factors independently predicted child pornography viewing and explained 42 % of the variance: ever had sex with a male, likely to have sex with a child aged 12-14, likely to have sex with a child 12 or less, perception of children as seductive, having friends who have watched child pornography, frequent pornography use, and ever viewed violent pornography. From these, a 6-item Child Pornography Correlates Scale was constructed and then cross-validated in a similar but independent Norwegian sample.

    Full Text Available The purpose of this study was to determine the relationship between unilateral squat strength and measures of static balance to compare balance performance between the dominant and non-dominant leg. Seventeen apparently healthy men (mean mass 90.5 ± 20.9 kg and age 21.7 ± 1.8 yrs and 25 women (mean mass 62.2 ± 14.5 kg and age 21.9 ± 1.3 yrs completed the study. Weight bearing unilateral strength was measured with a 1RM modified unilateral squat on the dominant and non-dominant leg. The students completed the stork stand and wobble board tests to determine static balance on the dominant and non-dominant leg. Maximum time maintained in the stork stand position, on the ball of the foot with the uninvolved foot against the involved knee with hands on the hips, was recorded. Balance was measured with a 15 second wobble board test. No significant correlations were found between the measurements of unilateral balance and strength (r values ranged between -0.05 to 0.2 for the men and women. Time off balance was not significantly different between the subjects' dominant (men 1.1 ± 0.4 s; women 0.3 ± 0.1 s and non-dominant (men 0.9 ± 0.3 s; women 0.3 ± 0.1 s leg for the wobble board. Similar results were found for the time balanced during the stork stand test on the dominant (men 26.4 ± 6.3 s; women 24.1 ± 5.6 s and non-dominant (men 26.0 ± 5.7 s; women 21.3 ± 4.1 s leg. The data indicate that static balance and strength is unrelated in young adult men and women and gains made in one variable after training may not be associated with a change in performance of the other variable. These results also suggest that differences in static balance performance between legs can not be determined by leg dominance. Similar research is needed to compare contralateral leg balance in populations who participate in work or sport activities requiring repetitive asymmetrical use. A better understanding of contralateral balance performance will help

    2010-01-01

    Background Currently, there is insufficient evidence available regarding the relationship between level of physical fitness and health-related quality of life (HRQoL) in younger adults. Therefore, the aim of the present study was to investigate the impact of measured cardiovascular and musculoskeletal physical fitness level on HRQoL in Finnish young men. Methods In a cross-sectional study, we collected data regarding the physical fitness index, including aerobic endurance and muscle fitness, leisure-time physical activity (LTPA), body composition, health, and HRQoL (RAND 36) for 727 men [mean (SD) age 25 (5) years]. Associations between HRQoL and the explanatory parameters were analyzed using the logistic regression analysis model. Results Of the 727 participants who took part in the study, 45% were in the poor category of the physical fitness, while 37% and 18% were in the satisfactory and good fitness categories, respectively. A higher frequency of LTPA was associated with higher fitness (p physical functioning, mental health, and vitality were associated with better physical fitness. When the HRQoL of the study participants were compared with that of the age- and gender-weighted Finnish general population, both the good and satisfactory fitness groups had higher HRQoL in all areas other than bodily pain. In a regression analysis, higher LTPA was associated with three dimensions of HRQoL, higher physical fitness with two, and lower number of morbidities with all dimensions, while the effect of age was contradictory. Conclusions Our study of Finnish young men indicates that higher physical fitness and leisure-time physical activity level promotes certain dimensions of HRQoL, while morbidities impair them all. The results highlight the importance of health related physical fitness while promoting HRQoL. PMID:20109241

  18. Extraversion, neuroticism, and sexual behavior: interrelationships in a sample of young men.

    1986-12-01

    In his theory on sexuality and personality Eysenck proposed a positive correlation between extraversion and intensified sexual behavior and between neuroticism and problems in sexual behavior. An earlier study with married persons did not show any of these correlations. It was hypothesized that this connection exists only for unmarried persons who are not engaged in long-lasting relationships, because in the latter the quality of the relationship determines the sexual interaction. Within a sample of young unmarried men there was a positive correlation between extraversion and items in which the person described earlier sexual activity with more persons and in higher frequency. No correlation was found with neuroticism. There were also slight correlations with other personality and social attitude scales. Because of the correlation with an acting-out personality scale, the findings were interpreted from a social-psychological perspective. In our culture the young male is expected to take the initiative in sexual interaction which the extraverted young male can realize better than one who is introverted.

    Young black men who have sex with men (YBMSM) account for 48% of 13–29 year old HIV-positive men who have sex with men (MSM) in the USA. It is important to develop an effective HIV prevention approach that is grounded in the context of young men’s lives. Towards this goal, we conducted 31 interviews with 18–30 year old YBMSM in the San Francisco-Oakland Bay Area. This paper examines the roles of religion and spirituality in YBMSM’s lives, which is central in the lives of many African Americans. Six prominent themes emerged: (1) childhood participation in formal religious institutions; (2) the continued importance of spirituality among YBMSM; (3) homophobia and stigmatisation in traditional black churches; (4) tension between being an MSM and Christian; (5) religion and spirituality’s impact on men’s sense of personal empowerment and coping abilities; and (6) treatment of others and building compassion. Findings suggest that integrating spiritual practice into HIV prevention may help programmes be more culturally grounded, thereby attracting more men and resonating with their experiences and values. In addition, faith-based HIV/AIDS ministries that support HIV-positive YBMSM may be particularly helpful. Finally, targeting pastors and other church leaders through anti-stigma curricula is crucial.

    Black men who have sex with men (BMSM) are at considerable risk for HIV infection. A convenience sample of BMSM (n=252) attending nightclubs in three North Carolina cities was surveyed to investigate factors associated with unprotected anal intercourse (UAI). About 45% reported UAI in the past 2 months. BMSM who strongly agreed that their male friends used condoms for anal sex were significantly less likely to report any UAI. Recently incarcerated men were significantly more likely to report unprotected insertive anal sex. In secondary analyses, men who reported experiencing discrimination based on their race and nongay identified men reported more favorable peer norms for condom use. Men who reported that their family disapproved of their being gay were more likely to have been incarcerated in the past 2 months. HIV prevention for BMSM must promote supportive peer norms for condom use and address incarceration, racial discrimination, and family disapproval.

    Full Text Available Objective To investigate the incidence of acute mountain sickness (AMS among young men from different regions when arriving in Tibet, and explore the medical geographic differences of high altitude adaptability of people from different regions. Methods Cluster sampling survey of AMS incidence was performed among the young men from different regions when arriving in high altitude area, by using the AMS symptoms scoring method, and the military standards were employed as reference, for classifying and scoring. For distinguishing the differences of geographic environment, the systematic cluster analysis of natural geographical factors of their native places was performed and verified by nonparametric tests. The one-way ANOVA was used to analyze the differences of AMS symptom scores among young men from different regions. Results The native places of the studied subjects were divided into 5 regions by cluster analysis, and the geographic factors among the 5 regions were found to be significantly different (P<0.01. It was found that there were significant differences in the AMS incidence among people came from different regions (P<0.05. Specifically, the AMS incidence was significantly higher (P<0.05 in people from region 2 than in people from region 3, 4 and 5. In terms of main symptoms of AMS, the incidence of headache in people from region 2 was 82.8%, and it was significantly different (P<0.05 from that of those coming from regions 3, 4 and 5; the incidence of nausea and vomiting was 37.9%, and it was significantly different (P<0.05 from that of those coming from region 3; the incidence of fatigue and drowsiness was 724.% and 27.6%, and it was significantly different (P<0.05 from that of those coming from region 5. The incidence of vertigo in people from region 1 and 3 was significantly different (P<0.05 from that of those coming from region 5.

    Web-based approaches, specifically social media sites, represent a promising approach for recruiting young gay and bisexual men for research studies. Little is known, however, about how the performance of social media advertisements (ads) used to recruit this population is affected by ad content (ie, image and text). The aim of this study was to evaluate the effects of different images and text included in social media ads used to recruit young gay and bisexual men for the pilot test of a Web-based human papillomavirus (HPV) vaccination intervention. In July and September 2016, we used paid Facebook advertisements to recruit men who were aged 18-25 years, self-identified as gay or bisexual, US resident, and had not received HPV vaccine. A 4x2x2 factorial experiment varied ad image (a single young adult male, a young adult male couple, a group of young adult men, or a young adult male talking to a doctor), content focus (text mentioning HPV or HPV vaccine), and disease framing (text mentioning cancer or a sexually transmitted disease [STD]). Poisson regression determined whether these experimental factors affected ad performance. The recruitment campaign reached a total of 35,646 users who viewed ads for 36,395 times. This resulted in an overall unique click-through rate of 2.01% (717/35,646) and an overall conversion rate of 0.66% (241/36,395). Reach was higher for ads that included an image of a couple (incidence rate ratio, IRR=4.91, 95% CI 2.68-8.97, PFacebook ads are a convenient and cost-efficient strategy for reaching and recruiting young gay and bisexual men for a Web-based HPV vaccination intervention. To help optimize ad performance among this population, researchers should consider the importance of the text and image included in the social media recruitment ads.

    Full Text Available The bone tissue is metabolically active. Throughout the entire life, it undergoes changes in the form of bone resorption processes which are successive, with the participation of the resorbing cells and bone formation processes. The aim of the study was to evaluate mineral density and bone mass tissue and the lipid profile, BMI, total body fat in young females and males. The study involved 100 people (50 females and 50 males studying in Warsaw at the age of 23,2 ± 4,0 years. The densitometry method of the forearm was used for the assessment of bone mineral density (BMD and bone mass (BMC. The method of bioelectrical impedance was used for the assessment of body components. Basic body dimensions and indicators were assessed using anthropometric measurements. Body height, body mass and the needs for the densitometry study of the forearm were measured. The total cholesterol concentration was determined in the blood serum using diagnostic kits, as well as high-density lipoprotein (HDL-C and triglycerides. The concentration of the low-density lipoprotein (LDL-C was calculated. While in men the occurrence of a significant, positive correlation was stated between the concentration of the HDL cholesterol fraction and the mineral density and T-score index in the ultra-distal point, the analysis of the compounds of mineral density (BMD, bone mass (BMC of the forearm, T-score index with somatic features in women showed a significant, positive relation between the body weight and the bone mass mineral density and T-score indicator in the proximal point. Also, a significant weak, positive correlation was observed between the BMI, the mineral density and T-score indicator in the proximal point. In men, the occurrence of significant, positive correlations was stated between the body weight and BMC, BMD, T-score indicator in the proximal point of the forearm bone and ultra-distal point. Similar relations were observed between the BMI, mineral density, T

    Although religion and spirituality can promote healthy behaviours and mental well-being, negative religious experiences may harm sexual minority men's health. Despite increasing vulnerability to HIV infection among young gay and bisexual men, few studies examine how religion and spirituality might affect them. To this end, we interviewed young gay and bisexual men who were diagnosed with HIV infection during January 2006-June 2009. Questionnaires assessed religious service attendance, disclosure of sexuality within religious communities, and beliefs about homosexuality being sinful. A subset described religious and spiritual experiences in qualitative interviews. We calculated the prevalence of religion- and spirituality-related factors and identified themes within qualitative interviews. Among men completing questionnaires, 66% currently attended religious services, 16% believed they could disclose their sexuality at church, and 37% believed homosexuality was sinful. Participants who completed qualitative interviews commonly discussed religious attendance and negative experiences within religious settings. They often expressed their spirituality through prayer, and some used it to cope with adverse experiences. These data suggest that religion and spirituality are notable factors that shape young, HIV-infected gay and bisexual men's social contexts. Programmes and interventions that constructively engage with religious institutions and are sensitive to spiritual beliefs may promote these men's health.

    Qualitative data can be a powerful tool in developing interventions for substance use and other HIV-risk behaviors. Mixed-methods design offers researchers the ability to obtain data that provides both breadth and depth to their research. However, the integration of qualitative data in mixed-methods research has been limited. This paper describes the qualitative design of the Healthy Young Men’s Study, a longitudinal mixed-method study with an ethnically diverse cohort of young men who have sex with men (YMSM) (N=526) in Los Angeles. Integral to this discussion is how a mixed-methods study can address common challenges such as sampling, representation and integration. PMID:20222783

    Microgravity due to prolonged bed rest may cause changes in cerebral circulation, which is related to brain function. We evaluate the effect of simulated microgravity due to a 6° head-down tilt bed rest experiment on executive function among 12 healthy young men. Four kinds of psychoneurological tests—the table tapping test, the trail making test, the pointing test and losing at rock-paper-scissors—were performed on the baseline and on day 16 of the experiment. There was no significant difference in the results between the baseline and day 16 on all tests, which indicated that executive function was not impaired by the 16-day 6° head-down tilting bed rest. However, we cannot conclude that microgravity did not affect executive function because of the possible contribution of the following factors: (1) the timing of tests, (2) the learning effect, or (3) changes in psychophysiology that were too small to affect higher brain function.

    Neuroticism and extraversion are two core dimensions of personality and are considered to be associated with emotional disorders. We investigated resting state brain metabolic correlates of neuroticism and extraversion using a positron emission tomography. Twenty healthy young men completed an F-flurodeoxyglucose-PET scan at rest and the Korean version of the revised Eysenck Personality Questionnaire. Neuroticism was negatively correlated with regional glucose metabolism in prefrontal regions including the medial prefrontal cortex. Extraversion was positively correlated with metabolism in the right putamen. These results suggest close associations between resting state brain activity in the prefrontal and striatal regions and specific personality traits and thus contribute to the understanding of the neurobiological bases of predisposition to psychiatric disorders.

    The glucocorticoid (GC) hormone cortisol is the end product of the hypothalamic-pituitary-adrenal axis (HPA axis). Acute psychological stress increases HPA activity and GC release. In humans, chronic disturbances in HPA activity have been observed in affective disorders and in addictive behaviour. Recent research indicates that acute effects of GCs may be anxiolytic and increase reward sensitivity. Furthermore, cortisol acutely influences early cognitive processing of emotional stimuli. In order to extend such findings to more complex emotional-cognitive behaviour, the present study tested acute effects of 40 mg cortisol on motivated decision making in 30 healthy young men. Results showed that cortisol indeed increased risky decision making, as predicted. This effect occurred for decisions where making a risky choice could potentially yield a big reward. These results are discussed with respect to currently proposed mechanisms for cortisol's potential anxiolytic effect and GCs' involvement in reward systems.

    Retinol-binding protein 4 (RBP4) is a plasma protein which is elevated in obesity and type 2 diabetes. We aimed to investigate whether RBP4 represents a mechanism underlying the associations between low birth weight (LBW), high-fat diet, and insulin resistance. Forty-six young, lean men with low (n...... = 20) or normal (n = 26) birth weight underwent a 5-day high-fat high-calorie (HFHC) dietary intervention. In vivo glucose metabolism was assessed by euglycemic-hyperinsulinemic clamp, glucose tracer and intravenous glucose tolerance test techniques. Body composition was measured by a dual-energy x......, but is not determined by birth weight and seems not to be involved in short-term high-fat diet-induced insulin resistance....

    Age-related loss in muscle mass and strength impairs daily life function in the elderly. However, it remains unknown whether tendon properties also deteriorate with age. Cross-linking of collagen molecules provides structural integrity to the tendon fibrils and has been shown to change with age...... in animals but has never been examined in humans in vivo. In this study, we examined the mechanical properties and pyridinoline and pentosidine cross-link and collagen concentrations of the patellar tendon in vivo in old (OM) and young men (YM). Seven OM (67 +/- 3 years, 86 +/- 10 kg) and 10 YM (27 +/- 2...... contractions. Percutaneous tendon biopsies were taken and analyzed for hydroxylysyl pyridinoline (HP), lysyl pyridinoline (LP), pentosidine, and collagen concentrations. We found no significant differences in the dimensions or mechanical properties of the tendon between OM and YM. Collagen concentrations were...

    2013-02-01

    Full Text Available In this article we provide a critical reflection on the integrated use of solicited audio diaries, photography, and interviews in a study with disabled young men transitioning to adulthood. In the study, we developed a methodological approach for illuminating the intersectionality of gender, disability, and generation (life stage identities. Drawing from a critical Bourdieusian perspective, we suggest that rather than producing single or “true” accounts, the combination of methods can be used to elucidate how participants establish, maintain, and reform their identities in everyday practices. Furthermore, we discuss how participants' acts of data creation are analyzable events in themselves, wherein participants do work to establish, maintain, and reform their identities. We conclude with some lessons learned and future directions.

    There has been an increase in new HIV diagnoses among young men who have sex with men (YMSM) over the past decade in both UK and US contexts, with online sex-seeking implicated in driving this development. This study sought to examine YMSM's use of a variety of social and sexual networking websites and 'apps', and assess sexual risk behaviours. YMSM were recruited from across four countries in Britain and Ireland, via an online survey using convenience sampling. Data were collected from 2668 men, of whom 702 were aged 18-25 years. Facebook use was almost ubiquitous and for largely social reasons; sexual media use was common with 52% using gay sexual networking (GSN) websites frequently and 44% using similar apps frequently. We found increased odds of high-risk condomless anal intercourse associated with the length of time users had been using GSN websites and lower levels of education. We found no significant differences across the four countries in sexual risk behaviours. YMSM are a heterogeneous population with varied sexual health needs. For young men with digital literacy, individual-level online interventions, targeted and tailored, could be directed towards frequent users with lower levels of education. Variation in demographic characteristics of GSN websites and app users may affect who interventions are likely to reach, depending on where they are targeted. However, interventions, which may catch young men earlier, also provide a major opportunity for reducing sexual health inequalities. Published by the BMJ Publishing Group Limited.

    Full Text Available Racial disparities in health among African American men in the United States are extensive. In contrast to their White counterparts, African American men have more illnesses and die younger. African American men have colorectal cancer (CRC incidence and mortality rates 25% and 50% higher, respectively, than White men. Due to CRC’s younger age at presentation and high incidence among African American men, CRC screening is warranted at the age of 45 rather than 50, but little is known about younger African American men’s views of CRC screening. Employing survey design, the purpose of the study was to describe the male role norms, knowledge, attitudes, perceived subjective norms, and perceived barriers associated with screening for CRC among a non-random sample of 157 young adult African American men (ages 19-45. Sixty-seven percent of the study sample received a passing knowledge score (85% or better, yet no significant differences were found among the three educational levels (i.e., low, medium, high. More negative attitudes towards CRC screening correlated with the participants’ strong perceptions of barriers, but no extremely negative or positive male role norms and perceived subjective norms were found. The factors significantly associated with attitudes were family history of cancer (unsure, work status, and perceived barriers. Findings from this study provide a solid basis for developing structured health education interventions that address the salient factors shaping young adult African American men's view of CRC and early detection screening behaviors.

  7. The production of disability culture among young African-American men.

    During the past two decades, debate about disability definitions, concepts, models and policies has been led primarily by Western white middle class disability activists and scholars. This paper contributes to the discussion by examining how disability is conceived and disability culture is developed in a poor, African-American community. The recognition of disability as a defining identity and disability culture as a cohesive force is unusual in the African-American community, and we ask what conditions are necessary for such an identity and culture to develop. To address this question, in 1998 we began a 5 year ethnographic research project concerning young African-American men in the spinal cord injury unit of an inner city rehabilitation hospital in Chicago USA. Based on this research, we argue that there are three necessary conditions for a disability culture to emerge in a group of African-Americans who acquired their disability violently. First, is the perception of social alienation from family and fellow gang members. Second, is immersion in a supportive physical and social environment where disability meanings are produced, reinforced and passed on across generations. Third, is the development of personal narratives and metaphors that give meaning to disability, anchor behavioral changes and help to reconcile value conflicts. Our analysis allows us to understand a change in identity among these young men and the emergence of a shared disability culture represented through signs, symbols, language, rules and ceremonies. This analytical framework also permits us to re-examine disability culture in white society and in specific disability cultures such as deaf culture and to suggest that while there are similarities across groups, disability culture is not monolithic.

    This study investigated quality of life (QOL) in adolescent and young men with Duchenne muscular dystrophy (DMD). Health-related QOL and global QOL were assessed with the Short Form 36 (SF-36) and World Health Organization Quality of Life-BREF (WHOQOL-BREF). Associations between functional status and QOL were assessed. All domains of the SF-36 were below Taiwan norms (effect size: -14.2 to -0.5), especially Physical Function, Role Physical, and Social Function. Three of the four domains of the WHOQOL-BREF were below Taiwan norms (effect size: -2.0 to -0.7). The Physical Function of the SF-36 was moderately correlated with functional status (mobility, basic activities of daily living, and arm function). The Social Function of the SF-36 and Social Relationships of the WHOQOL-BREF were also moderately correlated with functional status (impairment, basic activities of daily living, and arm function). The adolescent and young men with DMD had poor health-related and global QOL. Poor QOL was related to both physical condition and social health. We suggest that rehabilitation programs focus on using assistive devices to facilitate arm function and encouraging participation in social activities to improve the QOL of patients with DMD. Implications for rehabilitation Duchenne muscular dystrophy (DMD) is a progressive muscle weakness disease that not only impacts physical health but also leads to poor quality of life in many domains. A valuable rehabilitation goal for patients with DMD is to encourage participation in social activities. Medical care and educational programs should plan a formal transition processes for patients with DMD from pediatric to adult care to maximum their quality of life. Arm function is associated with many domains of global quality of life, so a key element in improving quality of life may be to improve arm function.

    The alcohol purchase task (APT), which presents a scenario and asks participants how many drinks they would purchase and consume at different prices, has been used among students and small clinical samples to obtain measures of alcohol demand but not in large, general population samples. We administered the APT to a large sample of young men from the general population (Cohort Study on Substance Use Risk Factors). Participants who reported drinking in the past year (n=4790), reported on past 12 months alcohol use, on DSM-5 alcohol use disorder (AUD) criteria and on alcohol related consequences were included. Among the APT's demand parameters, intensity was 8.7 (SD=6.5) indicating that, when drinks are free, participants report a planned consumption of almost 9 drinks. The maximum alcohol expenditure (Omax) was over 35CHF (1CHF=1.1USD) and the demand became elastic (Pmax) at 8.4CHF (SD=5.6). The mean price at which the consumption was suppressed was 15.6CHF (SD=5.4). Exponential equation provided a satisfactory fit to individual responses (mean R(2): 0.8, median: 0.8). Demand intensity was correlated with alcohol use, number of AUD criteria and number of consequences (all r≥0.3, pelasticity parameter was weakly correlated with alcohol use in the expected direction. The APT measures are useful in characterizing demand for alcohol in young men in the general population. Demand may provide a clinically useful index of strength of motivation for alcohol use in general population samples. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    One of the central assumptions of Kohlberg's theory of moral development--that moral judgment is organized in structures of the whole--was examined. Thirty men and 30 women were given 2 dilemmas from Kohlberg's Moral Judgment Interview, a 3rd involving prosocial behavior, and a 4th involving impaired driving. Half the Ss responded to the prosocial and impaired-driving dilemmas from the perspective of a hypothetical character, and half responded from the perspective of the self. No sex or perspective differences in moral maturity were observed. Ss scored highest in moral maturity on Kohlberg's dilemmas, intermediate on the prosocial dilemma, and lowest on the impaired-driving dilemma. In partial support of Kohlberg's contention that his test assesses moral competence, there was a negative linear relationship between scores on his test and the proportion of Stage 2 judgments on the 2 other dilemmas. An interactional model of moral judgment is advanced.

    Full Text Available This study was conducted to examine the association between testosterone therapy and new myocardial infarction (MI and stroke events in a series of patients treated at Low T Centers across the United States, consisting of mainly young (mean age = 46, otherwise, healthy men. Electronic medical records were queried between the years 2009 and 2014 to identify patients diagnosed with hypogonadism, MI, and stroke, as indicated by ICD-9 codes. The incidence of MI and stroke events was compared to community-based registries. 39,936 patients recruited from 40 Low T Centers across the United States were treated and 19,968 met eligibility criteria for receiving testosterone treatment. The incidence rate ratio (IRR for MI in testosterone- (T- treated versus nontreated patients was 0.14 (C.I. = 0.08 to 0.18, P<0.0001 whereas the IRR for stroke for T-treated versus nontreated patients was 0.11 (C.I. = 0.02 to 0.13, P<0.0001. There was no evidence of worsening preexisting MI or stroke in patients treated with testosterone. The experience in Low T Centers shows that, in an injectable testosterone patient registry, testosterone is generally safe for younger men who do not have significant risk factors. Of patients that developed MI with testosterone, there was no association with testosterone or hematocrit levels.

    The exon-1 of the androgen receptor (AR) gene contains two repeat length polymorphisms which modify either the amount of AR protein inside the cell (GGN(n), polyglycine) or its transcriptional activity (CAG(n), polyglutamine). Shorter CAG and/or GGN repeats provide stronger androgen signalling and vice versa. To test the hypothesis that CAG and GGN repeat AR polymorphisms affect muscle mass and various variables of muscular strength phenotype traits, the length of CAG and GGN repeats was determined by PCR and fragment analysis and confirmed by DNA sequencing of selected samples in 282 men (28.6 ± 7.6 years). Individuals were grouped as CAG short (CAG(S)) if harbouring repeat lengths of ≤ 21 and CAG long (CAG(L)) if CAG >21. GGN was considered short (GGN(S)) or long (GGN(L)) if GGN ≤ 23 or >23, respectively. No significant differences in lean body mass or fitness were observed between the CAG(S) and CAG(L) groups, or between GGN(S) and GGN(L) groups, but a trend for a correlation was found for the GGN repeat and lean mass of the extremities (r=-0.11, p=0.06). In summary, the lengths of CAG and GGN repeat of the AR gene do not appear to influence lean mass or fitness in young men.

    Health research shows that knowing about health risks may not translate into behavior change. However, such research typically operationalizes health information acquisition with knowledge tests. Information scientists who investigate socially embedded information behaviors could help improve understanding of potential associations between information behavior-as opposed to knowledge-and health behavior formation, thus providing new opportunities to investigate the effects of health information. We examine the associations between information behavior and HIV testing intentions among young men who have sex with men (YMSM), a group with high rates of unrecognized HIV infection. We used the theory of planned behavior (TPB) to predict intentions to seek HIV testing in an online sample of 163 YMSM. Multiple regression and recursive path analysis were used to test two models: (a) the basic TPB model and (b) an adapted model that added the direct effects of three information behaviors (information exposure, use of information to make HIV-testing decisions, prior experience obtaining an HIV test) plus self-rated HIV knowledge. As hypothesized, our adapted model improved predictions, explaining more than twice as much variance as the original TPB model. The results suggest that information behaviors may be more important predictors of health behavior intentions than previously acknowledged.

    The aim of this study was to investigate the development of bone mineral density (BMD) and bone mineral content (BMC) in relation to peak height velocity (PHV), and to investigate whether late normal puberty was associated with remaining low BMD and BMC in early adulthood in men. In total, 501 men (mean ± SD, 18.9 ± 0.5 years of age at baseline) were included in this 5-year longitudinal study. Areal BMD (aBMD) and BMC, volumetric BMD (vBMD) and cortical bone size were measured using dual-energy X-ray absorptiometry (DXA) and pQCT. Detailed growth and weight charts were used to calculate age at PHV, an objective assessment of pubertal timing. Age at PHV was a strong positive predictor of the increase in aBMD and BMC of the total body (R(2) aBMD 11.7%; BMC 4.3%), radius (R(2) aBMD 23.5%; BMC 22.3%), and lumbar spine (R(2) aBMD 11.9%; BMC 10.5%) between 19 and 24 years (p bone size, whereas cortical and trabecular vBMD were 0.7% (p males was associated with a substantial catch up in aBMD and BMC in young adulthood, leaving no deficits of the lumbar spine, femoral neck, or total body at age 24 years.

    The purpose of this study was to evaluate the possible effects of risk factors on distortion product otoacoustic emissions (DPOAEs) in young adult men with normal hearing. Four hundred thirty-six United States Marine recruit men (mean age = 19.2 years +/- 1.8 years; age range = 17-29 years) participated in this study. Questionnaires were given to each recruit to obtain demographic data and history of noise exposure, solvent exposure, smoking history, and hearing-related histories. Otoscopy, tympanometry, pure-tone air-conduction audiometry (2.0-8.0 kHz) and DPOAEs (2.3-8.0 kHz) were measured. DPOAE levels were lower in Not Hispanic or Latino recruits, in heavy smokers, in recruits who reported loud live music exposure and ringing in their ears after noise exposure. These differences were not statistically significant at all frequencies. Recruits with multiple risk factors had the lowest DPOAEs as compared to recruits with fewer, or no, risk factors; these differences were not statistically significant. Obtaining risk factor data as part of an audiometric evaluation is important even though the individual may have normal hearing.

    The interassay variability found in the measurement of testosterone (T) levels warrants the need for laboratories to validate their methods to establish trustworthy cut-off points for diagnosis of male hypogonadism. The aims of this study were to validate measurement of total T (TT) at our laboratory in order to obtain reference ranges for TT, calculated free T (CFT), calculated bioavailable T (CBT), and salivary T (ST) in healthy young men from the Mediterranean region, and to evaluate the potential clinical value of ST by establishing its correlation with serum T. An observational, cross-sectional study with sequential sampling. men aged 18-30 years with body mass index (BMI)9.7 nmol/L, CFT>0.22 nmol/L, and/or CBT>4.9 nmol/L make the presence of biochemical hypogonadism unlikely. According to the correlation between serum and ST, the clinical value of ST remains to be established. Copyright © 2014 SEEN. Published by Elsevier Espana. All rights reserved.

    Full Text Available Background &objectives: Glutamine has antioxidant properties and can be used to treat some diseases. This study was conducted to assess the effect of one-week glutamine supplementation on oxidative stress indices in young healthy men.   Methods: Nineteen active healthy men volunteered for this study. This study was conducted in biochemistry lab of Ardabil branch of Islamic Azad University in Spring 2014. Participants were randomized in a double-blind placebo-controlled method into two groups: Glutamine (n = 9 and placebo group (n = 10. The participants took supplement (0.15 g/kg glutamine + 15g sweetener + 250ml water or placebo (15g sweetener + 250ml water daily for 7 days before main trial.Fasting blood samples were taken before and after supplementation. Total antioxidant capacity (TAC of plasma, reduced glutathione (GHS level of serum, and malondialdehyde (MDA of plasma were measured.   Results: GHS significantly increased after treatment compared with pre-treatment in Glutamine group (p0.05.   Conclusions: These results showed that one-week daily oral supplementation of glutamine has been able to increase GHS probably because of greater glutamine availability .

    Music and high levels of sound have not traditionally been associated with risk-taking behaviors. Loud music may intensify and bring more power and meaning to the musical experience, but it can at the same time be harmful to hearing. The present study aims to increase the knowledge about young women's and men's risk judgement and behaviour by investigating patterns in adolescent risk activities among 310 adolescents aged 15-20 (143 women; 167 men). The Australian instrument ARQ was used with additional questions on hearing risks and a factor analysis was conducted. The main results showed that the factor structure in the judgement and behavior scale for Swedish adolescents was rather different from the factor structure in the Australian sample. Also, the factor structure was not similar to the Australian sample split on gender. The results are discussed from a gender- and existential perspective on risk taking, and it is emphasized that research on risk behavior needs to reconceptualize stereotypical ideas about gender and the existential period in adolescence.

    The Internet has opened many doors with its accessibility to information, entertainment and web-based communities. For young men who have sex with men (YMSM), the Internet can provide access to information on relevant sexual behavior and health information, stories from other men about relationship issues, and a venue for locating potential sexual and dating partners. Understanding YMSM's motivations for going online for information, advice or sexual relationships, is important as the Internet becomes increasingly used not only as a space to find sexual partners, but also as a venue for HIV and STI interventions. Having an understanding of the risks associated with searching for partners online, and how and why YMSM use the Internet for a variety of purposes, can inform the development of more effective Internet-based risk reduction programs. This article presents qualitative and quantitative data from the Healthy Young Men's Study, a longitudinal study of an ethnically diverse cohort of 526 YMSM. Qualitative interviews (N = 24) described not only the prevalence of using the Internet for finding sexual partners and the possible benefits and risks associated with that practice, but also the processes and perceptions of using this mechanism. Our data indicate that YMSM used the Internet to find information related to sex and sexuality, seek friendships, sexual partners as well as "hook-ups" or casual sex. Findings were presented in relation to how YMSM researchers and interventionists can identify how to most effectively reach YMSM through online methods.

    Young men who have sex with men (YMSM) continue to be at elevated risk for substance use; however, models explaining this phenomenon have often focused on a limited array of explanatory constructs. This study utilizes Social Action Theory (SAT) as a framework to address gaps in research by documenting the social, behavioral, and demographic risk factors associated with illicit drug use among YMSM. Structural equation modeling was used to apply SAT to a cross-sectional sample of 526 men from the Healthy Young Men Study, a longitudinal study of substance use and sexual risk behavior among YMSM in Los Angeles. The final model possessed very good fit statistics (Comparative Fit Index (CFI) = 0.936, Tucker-Lewis Index (TLI) = 0.925, Root Mean Square Error of Approximation (RMSEA) = 0.040) indicating that SAT is appropriate for use with YMSM. Substance use interventions for YMSM could be enhanced by employing SAT as conceptualized in this study and using a multitargeted strategy for impacting illicit drug use.

    Several case-control studies have investigated whether Y chromosome haplogroups or deletions are associated with spermatogenic failure. However, the relationships between Y chromosome haplogroups or deletions and semen quality in general population have not been elucidated. In this study, we assessed relationships between Y chromosome haplogroups or deletions and semen parameters in 791 fertile Japanese men and 1221 young men from the general Japanese population. We found that the haplogroup D2 (M55 lineage) was significantly associated with lower semen parameters, especially total motile sperm count (P = 0.00051, beta = -0.097), in men from the general population but not in fertile men. In addition, we found that the gr/gr subdeletion was associated with semen quality and in particular, strongly associated with decreased sperm motility (P = 0.00041, beta = -3.14) and total motile sperm count (P = 0.00031, beta = -0.099) in men from the general population but not in fertile men. The combined analysis of fertile Japanese men and men from the general Japanese population showed that the haplogroup D2 (M55 lineage) and the gr/gr subdeletion were strongly associated with reduced sperm motility (P = 0.00056, beta = -2.71, and P = 7.7 × 10(-5), beta = -3.05, respectively) and that haplogroup O2b1 was strongly associated with elevated sperm motility (P = 0.00089, beta = 2.94). These observations add further support for the view that the gr/gr subdeletion diminishes sperm motility that consequently may result in male infertility.

    Investigating the ways in which barrier methods such as condoms may affect penile sensory thresholds has potential relevance to the development of interventions in men who experience negative effects of condoms on sexual response and sensation. A quantitative, psychophysiological investigation examining the degree to which sensations are altered by condoms has, to date, not been conducted. The objective of this study was to examine penile vibrotactile sensitivity thresholds in both flaccid and erect penises with and without a condom while comparing men who do and those who do not report condom-associated erection problems (CAEP). Penile vibrotactile sensitivity thresholds were assessed among a total of 141 young, heterosexual men using biothesiometry. An incremental two-step staircase method was used and repeated three times for each of four conditions. Intra-class correlation coefficients (ICCs) were calculated for all vibratory assessments. Penile vibratory thresholds were compared using a mixed-model analysis of variance. Penile vibrotactile sensitivity thresholds with and without a condom, erectile function measured by International Index of Erectile Function Questionnaire, and self-reported degree of erection. Significant main effects of condoms (yes/no) and erection (yes/no) were found. No main or interaction effects of CAEP were found. Condoms were associated with higher penile vibrotactile sensitivity thresholds (F[1,124] = 17.11, P erect penis than with a flaccid penis (F[1,124] = 4.21, P = 0.042). The current study demonstrates the feasibility of measuring penile vibratory thresholds with and without a condom in both erect and flaccid experimental conditions. As might be expected, condoms increased penile vibrotactile sensitivity thresholds. Interestingly, erections were associated with the highest thresholds. Thus, this study was the first to document that erect penises are less sensitive to vibrotactile stimulation than flaccid penises.

    This study employed a social-cognitive theoretical perspective to assess the interactions of behavioral, cognitive, and situational factors to understand better how young male sex workers (MSWs) entered the sex trade industry. As part of a larger project examining male escorts working for a single agency, MSWs (n = 38) were interviewed about their work and personal lives. Interviews were transcribed and analyzed thematically. As predicted by a social-cognitive perspective, results supported reciprocal influences of behavior and environment, environment and cognition, and behavior and cognition. MSWs developed more self-efficacy around sex work behaviors and more positive outcome expectations with experience; moral conflict and lack of attraction to clients limited MSWs' self-efficacy. Key variables for sex work appeared to be cognitive in nature-mostly represented by a decreased commitment to normative social/sexual values, the specific nature of which may have varied by sexual orientation. Findings support the contention that social-cognitive theory can effectively model entry of young men into sex work. Social-cognitive theory provides a broad umbrella underneath which various explanations for male sex work can be gathered.

    Exercise is a potent stimulus for release of growth hormone (GH), cortisol, testosterone and prolactin, and prolonged exercise inhibits insulin secretion. These responses seem to be specific to the type of exercise but this has been poorly characterised primarily because they have not been compared during exercise performed by the same individuals. We investigated hormone responses to resistance, sprint and endurance exercise in young men using a repeated measures design in which each subject served as their own control. Eight healthy non-obese young adults (18-25 years) were studied on four occasions in random order: 30-s cycle ergometer sprint (Sprint), 30-min resistance exercise bout (Resistance), 30-min cycle at 70 % VO(2max) (Endurance), and seated rest in the laboratory (Rest). Cortisol, GH, testosterone, prolactin, insulin and glucose concentrations were measured for 60 min after the four different interventions. Endurance and sprint exercise significantly increased GH, cortisol, prolactin and testosterone. Sprint exercise also increased insulin concentrations, whereas this decreased in response to endurance exercise. Resistance exercise significantly increased only testosterone and glucose. Sprint exercise elicited the largest response per unit of work, but the smallest response relative to mean work rate in all hormones. In conclusion, the nature and magnitude of the hormone response were influenced by exercise type, perhaps reflecting the roles of these hormones in regulating metabolism during and after resistance, sprint and endurance exercise.

    Young men who have sex with men (MSM) experience multiple health disparities, including alcohol and drug use, partner violence, victimization due to sexual orientation, and HIV infection. Syndemic theorists explain the clustering of these disparities among adult MSM as a result of cultural marginalization. To date, research on a similar emerging syndemic among young MSM has been limited to quantitative studies. This study seeks to better understand these disparities, and how they may cluster together, via qualitative interviews with 21 ethnically diverse, HIV infected young MSM aged 18-24 years old. These youth report a lack of gay-specific HIV prevention education, absence of role models, and lack of productive future goal-related activities as factors related to their acquisition of HIV, and downplay substance use as a factor. Although not necessarily the components traditionally cited by syndemic theorists, these findings support the notion that multiple factors of cultural marginalization cluster together in the lives of young MSM, and underscore the importance of community-level interventions, such as sexual health education, access to mentors, and assistance with future goal setting and planning.

    In this paper we examine the sexual identities of Latino men who have sex with men and women, in which an analysis was made of 150 sexual histories of Latino men aged 18-60. This study asks how the bisexual identity and experience of stigma is different for Latino men along the generational spectrum and how do these differences relate to kinship support and gender ideology? In the process of analysis, two main clusters of characteristics were identified to reflect this population: young men aged 18-25, whose open bisexual identity correlated positively with kinship/peer support and flexible gender and sexual roles, and men aged 26-60, who refused or were reluctant to identify as bisexual despite the fact that they were sexually active with both men and women. This group as a whole had less kinship and peer support, were more likely to identify with traditional gender roles and were less sexually versatile. Finally, a third group reflected Latino men across the generational divide who were less concerned with same-sex stigma, but who nevertheless felt the bisexual label to be confining, illegitimate or otherwise negative.

  2. Gender differences in associations of sexual and romantic stimuli: do young men really prefer sex over romance?

    Thompson, Ashley E; O'Sullivan, Lucia F

    2012-08-01

    Theory and research emphasize differences in men's and women's sexual and romantic attitudes, concluding that men have stronger preferences for sexual than romantic stimuli as compared to women. However, most of the research on gender differences have relied on self-reports, which are plagued by problems of social desirability bias. The current study assessed young men's and women's implicit attitudes toward sexual and romantic stimuli to test whether, in fact, men have a stronger preference for sexual over romantic stimuli compared to women. We also assessed associations between implicit and explicit attitudes, as well as sex role ideology and personality. College students (68 men and 114 women) completed an Implicit Association Test (IAT) that assessed strengths of associations of sexual and romantic stimuli to both pleasant and unpleasant conditions. Results revealed that both men and women more strongly associated romantic images to the pleasant condition than they associated the sexual images to the pleasant condition. However, as predicted, women had a stronger preference toward romantic versus sexual stimuli compared to men. Our study challenges a common assumption that men prefer sexual over romantic stimuli. The findings indicate that measures of implicit attitudes may tap preferences that are not apparent in studies relying on self-reported (explicit) attitudes.

    Sexually transmitted infection testing rates among young men remain low, and their disengagement from sexual health services has been linked to enactments of masculinity that prohibit or truncate discussions of sexual health. Understanding how men align with multiple masculinities is therefore important for tailoring interventions that appropriately respond to their needs. We draw on 32 in-depth interviews with 15-24-year-old men to explore the discourses that facilitate or shut down sexual health communication with peers and sex partners. We employ a critical discourse analysis to explore how men's conversations about sexual health are constituted by masculine hierarchies (such as the ways in which masculinities influence men's ability to construct or challenge and contest dominant discourses about sexual health). Men's conversations about sexual health focused primarily around their sexual encounters - something frequently referred to as 'guy talk'. Also described were situations whereby participants employed a discourse of 'manning up' to (i) exert power over others with disregard for potential repercussions and (ii) deploy power to affirm and reify their own hyper-masculine identities, while using their personal (masculine) power to help others (who are subordinate in the social ordering of men). By better understanding how masculine discourses are employed by men, their sexual health needs can be advanced.

    Whether to use young male or young female reference data to calculate bone mineral density (BMD) T-scores in men remains controversial. The third National Health and Nutrition Examination and Survey (NHANES III) data show that the mean and standard deviation of femoral neck and total hip BMD is greater in young men than young women, and therefore differences in T-scores at these sites using NHANES III female vs male norms becomes less as BMD decreases. In contrast, manufacturer-specific reference databases generally assume similar standard deviations of BMD in men and women. Using NHANES III reference data for the femoral neck and total hip, respectively we found that men with T-scores of -2.5 when young male norms are used have T-scores of -2.4 and -2.3 when young female norms are used. Using manufacturer-specific reference data, we found that men with T-scores of -2.5 when young male norms are used at the femoral neck, total hip, lumbar spine, or one-third of the forearm would have T-scores ranging from -2.4 to -0.4 when young female norms are used, depending on skeletal site and densitometer manufacturer. The change of proportions of men diagnosed with osteoporosis when young female norms are used instead of young male reference data differs substantially according to skeletal site and densitometer manufacturer.

    Human cytomegalovirus (CMV) infection is associated with a higher risk of cardiovascular disease in immunocompromised organ transplant patients. It has been linked with the pathogenesis of elevated arterial blood pressure. However, controversy exists as to whether CMV infection is associated with endothelial function, and little is known about its role as a potential risk factor for early atherosclerosis development at a young age. We aimed to discover if CMV antibody titres are associated with early vascular changes (carotid intima-media thickness, carotid artery distensibility and brachial artery flow-mediated dilation), blood pressure elevation or other traditional cardiovascular risk factors. CMV antibody titres were measured in 1074 women and 857 men (aged 24-39 years) taking part in the Cardiovascular Risk in Young Finns study. CMV antibody titres were significantly higher in women compared to men. In men, high CMV antibody titres were associated directly with age (P blood pressure elevation, and associated inversely with flow-mediated dilation (P = 0·014). In women, CMV antibody titres did not associate with any of the analysed parameters. In a multivariate regression model, which included traditional atherosclerotic risk factors, CMV antibody titres were independent determinants for systolic (P = 0·029) and diastolic (P = 0·004) blood pressure elevation and flow-mediated dilation (P = 0·014) in men. High CMV antibody titres are associated independently with blood pressure and brachial artery flow-mediated dilation in young men. This association supports the hypothesis that common CMV infection and/or an immune response to CMV may lead to impaired vascular function at a young age. © 2012 The Authors.

    Full Text Available Abstract Background Young men involved in the criminal justice system face disproportionately high rates of sexual risk behavior, drug, use, and violence. Little is known about how their involvement in sex partnerships might mitigate their unique health and social risks. This study explores whether sex partner experience protects against harmful sexual behaviors, drug problems, violence, and recidivism in 16-18-year-old Black and Latino men leaving a US jail. Methods Data were drawn from the Returning Educated African-American and Latino Men to Enriched Neighborhoods (REAL MEN study conducted between 2003-2007, which tracked 552 adolescents during their time in a New York City jail and 397 of them one year after their release. Logistic regression was used to examine the relationship between sex partner experience and sex behavior, drug use, violence, and recidivism. Results This study indicates that young men who have long-term sex partners prior to incarceration are less likely to be inconsistent condom users (OR = 0.50, p ≤ 0.01, have sex while high on drugs/alcohol (OR = 0.14, p ≤ 0.001, use marijuana daily (OR = 0.45, p ≤ 0.001, and carry weapons during illegal activity (OR = 0.58, p ≤ 0.05, especially compared with peers who simultaneously are involved with long-term and casual "short-term" sex partners. However, the positive effects of having a long-term sex partner generally do not apply over time - in this case, one year after being released from jail. Aside from sexual partners, factors such as employment and housing stability predict whether these young men will experience positive or negative outcomes post-incarceration. Conclusions This study highlights the importance and potential benefits of health interventions that engage young Black and Latino men who are involved in the criminal justice system in the US, as well as their sex partners, in health promotion programs. The study also confirms the need for programs that

    Men played an important role in nursing in colonial Australia. However the number of men undertaking nursing duties declined dramatically in the second half of the nineteenth century. Reasons for this are explored in relation to ramifications of the introduction of the Nightingale pattern of nurse training in Australia, which occurred within the Victorian ethos of gentility and decorum. In this context, nursing came to be seen as a calling that was natural and appropriate for women. The controlled, decorous ambience of nursing, its subservient relationship to medicine and the attractiveness to employers of female pay rates are all associated with the decline in male participation over this period.

    Objectives. We explored gender role strain (GRS) arising from conflict between homosexuality and cultural conceptions of masculinity among young Black men who have sex with men (MSM). Methods. We conducted a categorical analysis (a qualitative, 3-stage, iterative analysis) of data from studies conducted in 2001 to 2006, which interviewed 35 men aged 18 to 24 years in 3 New York cities and Atlanta, Georgia. Results. Participants described rigid, often antihomosexual expectations of masculinity from their families, peers, and communities. Consistent with GRS, this conflict and pressure to conform to these expectations despite their homosexuality led to psychological distress, efforts to camouflage their homosexuality, and strategies to prove their masculinity. Participants believed this conflict and the associated experience of GRS might increase HIV risk through social isolation, poor self-esteem, reduced access to HIV prevention messages, and limited parental-family involvement in sexuality development and early sexual decision-making. Conclusions. Antihomosexual expectations of masculinity isolate young Black MSM during a developmental stage when interpersonal attachments are critical. GRS may influence sexual risk behavior and HIV risk and be an important target for HIV prevention.

    Aim:To investigate the flaccid and stretched penile sizes of young Korean men and their complexes or pride about their penile size. Methods: After an explanation and agreement to the purpose and methods of this study,123 Korean men in their early 20's visiting the Jinhae Military General Hospital were included in the study. The flaccid penile length, flaccid mid-shaft circumference, stretched length and pre-pubic bone fat pad depth were measured in a warm comfortable environment. The accuracy the subjects assessed their penile size was investigated by asking them to rate their penile size, as ‘very small', ‘small', ‘normal', ‘large' or ‘very large'. All subjects were asked to completethe Minnesota multiphasic personality inventory (MMPI) test. Results: The mean flaccid length, flaccid cireumfereace,stretched length and fat pad depth of the 123 subjects were (6.9 ± 0.8) cm, (8.5 ± 1.1) cm, (9.6± 0.8) cm and (1.1± 0.4) cm, respectively. The answer distribution on penile size was 1 (0.8 %) ‘very small', 29 (23.6 %) ‘small', 86(69.9 %) ‘normal', 6 (4.9 %) ‘large' and 1 (0.8 %)‘'very large'. Subjects who underestimated their penile size showed significantly higher scores on the hypochondriasis (Hs), depression (D) and psychasthenia (Pt) subscales of the MMPI than those in the Unbiased Group (P<0.05). Conclusion: In consultation, with a patient requesting penile augmentation, the urologist should consider the psychologic attitude of the patient to his penile size.

    Choi, Y, Akazawa, N, Zempo-Miyaki, A, Ra, S-G, Shiraki, H, Ajisaka, R, and Maeda, S. Acute effect of high-intensity eccentric exercise on vascular endothelial function in young men. J Strength Cond Res 30(8): 2279-2285, 2016-Increased central arterial stiffness is as an independent risk factor for cardiovascular disease. Evidence regarding the effects of high-intensity resistance exercise on vascular endothelial function and central arterial stiffness is conflicting. The purpose of this study was to examine the effects of acute high-intensity eccentric exercise on vascular endothelial function and central arterial stiffness. We evaluated the acute changes in endothelium-dependent flow-mediated dilation (FMD), low-flow-mediated constriction (L-FMC), and arterial stiffness after high-intensity eccentric exercise. Seven healthy, sedentary men (age, 24 ± 1 year) performed maximal eccentric elbow flexor exercise using their nondominant arm. Before and 45 minutes after eccentric exercise, carotid arterial compliance and brachial artery FMD and L-FMC in the nonexercised arm were measured. Carotid arterial compliance was significantly decreased, and β-stiffness index significantly increased after eccentric exercise. Brachial FMD was significantly reduced after eccentric exercise, whereas there was no significant difference in brachial L-FMC before and after eccentric exercise. A positive correlation was detected between change in arterial compliance and change in FMD (r = 0.779; p ≤ 0.05), and a negative correlation was detected between change in β-stiffness index and change in FMD (r = -0.891; p eccentric exercise. In this study, acute high-intensity eccentric exercise increased central arterial stiffness; this increase was accompanied by a decrease in endothelial function caused by reduced endothelium-dependent vasodilation but not by a change in endothelium-dependent vasoconstriction.

    To evaluate the sexual function of young men with spina bifida and the impact of the disorder on the quality of life (QOL). To assess sexual function and QOL by using self-administered questionnaires (International Index of Erectile Function [IIEF] and 36-Item Short Form Health Survey) for young men with spina bifida. We collected data from 47 young men with spina bifida between June 2013 and October 2013 at the spina bifida clinic of Severance Children's Hospital, Seoul, South Korea RESULTS: Of the 47 men who completed the IIEF, 24 (51.1%) had sexual intercourse at least once during the previous month, and the patients' sexual activity status had a significant association with their sexual function; however, the status of their sexual activity did not show any differentiation with their QOL scores. Concerning overall satisfaction in sexual activity, about 87% reported more than mild dysfunction; however, 67% and 50% had normal erectile function and orgasmic function, respectively. In 10 patients (41.7%) among them, the frequency of ejaculation problems ranged from "sometimes" to "most of the time" during sexual activity. The correlation between sexual function and QOL had a statistically significant association with the weak correlation (r = 0.496, P = .014). Sexual function should be evaluated routinely in patients with spina bifida because such patients experience sexual dysfunction, although sexual function did not directly show a significant correlation with the QOL in this study.

    Hegemonic masculinities (i.e., sets of socially accepted masculine behaviors and beliefs within a given time and culture) may affect the well-being of sexual minority men, yet quantitative relationships between these masculinities and well-being remain largely unexplored. Using data from a national cross-sectional survey of young sexual minority men ( N = 1,484; ages 18-24 years), the current study examined the relationship between parental gender policing during childhood and adolescence and subsequent substance use and psychological distress. Over one third of the sample (37.8%) reported their parent(s) or the person(s) who raised them had policed their gender, including the use of disciplinary actions. Using multivariable regression, this study examined the relationship between parental gender policing and psychological well-being and substance use, after adjusting for age, race/ethnicity, educational attainment, and current student status. Gender policing during childhood and adolescence was associated with recent substance use behaviors and psychological distress in multivariable models. A linear association between substance use behaviors and psychological distress and the number of disciplinary actions experienced during childhood and adolescence was also observed. Parents' attempts to police their sons' gender expression were associated with markers of distress among young sexual minority men. The relationship between parental gender policing during childhood and adolescence and distress among young sexual minority men are discussed.

    Full Text Available Background: The epidemiological evaluation of androgenetic alopecia (AGA is based mainly on direct observation and questionnaires. The international epidemiology and environmental risk factors of AGA in young Caucasian men remain unknown. Aim: To use photographs and data from the Internet to evaluate severe AGA and generate greater understanding of the international epidemiology of the disorder in young Caucasian men. Materials and Methods: A population-based cross-sectional study design was used. The sample included 26,340 Caucasian men aged 30 to 40 years who had uploaded profiles to two dating websites. Their photographs were evaluated for AGA and graded as follows: severe AGA (Norwood type VI-VII, non-severe AGA, and unknown. Epidemiological data were collected from the sites. Logistic regression was used to analyze the effect of risk factors on the prevalence of severe AGA. Results : The overall success rate for identifying severe AGA by indirect evaluation of Internet photographs was 94%. The prevalence of severe AGA was 15.33% overall and varied significantly by geographical region. The risk of having severe AGA was increased by 1.092 for every year of age between 30 and 40 years. Severe AGA was more prevalent in subjects with higher body mass index. Conclusions: Photographs from the Internet can be used to evaluate severe AGA in epidemiological studies. The prevalence of severe AGA in young Caucasian men increases with age and varies by geographical region. Body mass index is an environmental risk factor for severe AGA.

    Recent evidence suggests that young sexual minority men's sexual position identities (e.g., "top," "bottom," "versatile") may be governed by dynamic influences. Yet, no study has prospectively examined whether, how, and why this aspect of sexual minority men's sexuality changes over time. Consequently, the present study investigated the extent to which young sexual minority men use sexual position identities consistently over time, typical patterns of position identity change, explanations given for this change, and the correspondence of changing sexual position identities with changing sexual behavior and fantasies. A total of 93 young sexual minority men indicated their sexual position identity, behavior, and fantasies at two assessment points separated by 2 years. Following the second assessment, a subset (n = 28) of participants who represented the various sexual position identity change patterns provided explanations for their change. More than half (n = 48) of participants changed their sexual position identity. Participants showed a significant move away from not using sexual position identities toward using them and a significant move toward using "mostly top." Changes in position identity were reflected, although imperfectly, in changes in sexual behavior and largely not reflected in fantasy changes. Participants offered 11 classes of explanations for their identity changes referencing personal development, practical reasons, changing relationships, and sociocultural influences. Previous investigations of sexual minority men's sexual position identities have not adequately attended to the possibility of the changing use of the sexual position categories "top," "bottom," and "versatile" across young adulthood. Results of the present study suggest the possibility of a more fluid, context-dependent use of these terms than previously documented.

    Full Text Available INTRODUCTION: The association between childhood sexual abuse and HIV risk among men who have sex with men (MSM is well established. However, no studies have examined the potential impact of other forms of childhood maltreatment on HIV incidence in this population. METHODS: We explored the impact of child physical abuse (CPA on HIV seroconversion in a cohort of gay/bisexual men aged 15 to 30 in Vancouver, Canada. Cox proportional hazard models were used, controlling for confounders. RESULTS: Among 287 participants, 211 (73.5% reported experiencing CPA before the age of 17, and 42 (14.6% reporting URAI in the past year. After a median of 6.6 years follow-up, 16 (5.8% participants HIV-seroconverted. In multivariate analysis, CPA was significantly associated with HIV seroconversion (adjusted hazard ratio [AHR] = 4.89, 95% confidence interval (CI: 1.65-14.48, after controlling for potential confounders. CONCLUSION: Our study uncovered a link between childhood physical violence and HIV incidence. Results highlight an urgent need for screening of young gay and bisexual men for histories of violence, and social and structural supports to prevent HIV transmission in this population.

    Sexual violence against women and girls is commonplace in Papua New Guinea (PNG). While the experiences of women are rightly given central place in institutional responses to sexual violence, the men who perpetrate violence are often overlooked, an oversight that undermines the effectiveness of prevention efforts. This paper draws on interviews conducted with young men as part of a qualitative longitudinal study of masculinity and male sexuality in a rural highland area of PNG. It explores one aspect of male sexuality: men's narratives of sexual violence. Most striking from the data is that the collective enactment of sexual violence against women and girls is reported as an everyday and accepted practice amongst young men. However, not all women and girls were described as equally at risk, with those who transgress gender roles and roles inscribed and reinforced by patriarchal structures, at greater risk. To address this situation, efforts to reduce sexual violence against women and girls require an increased focus on male-centred intervention to critically engage with the forms of patriarchal authority that give license to sexual violence. Understanding the perceptions and experiences of men as perpetrators of sexual violence is a critical first step in the process of changing normative perceptions of gender, a task crucial to reducing sexual violence in countries such as PNG.

    In the United States, 36% of human papillomavirus (HPV)-related cancers occur among men. HPV vaccination can substantially reduce the risk of HPV infection; however, the vast majority of men are unvaccinated. This study developed and validated transtheoretical model-based measures for HPV vaccination in young adult men. Cross-sectional measurement development. Online survey of young adult men. Three hundred twenty-nine mostly college-attending men, ages 18 to 26. Stage of change, decisional balance (pros/cons), and self-efficacy. The sample was randomly split into halves for exploratory principal components analysis (PCA), followed by confirmatory factor analyses (CFA) to test measurement models. Multivariate analyses examined relationships between scales. For decisional balance, PCA revealed two uncorrelated five-item factors (pros α = .78; cons α = .83). For the self-efficacy scale, PCA revealed a single-factor solution (α = .83). CFA confirmed that the two-factor uncorrelated model for decisional balance and a single-factor model for self-efficacy. Follow-up analyses of variance supported the theoretically predicted relationships between stage of change, pros, and self-efficacy. This study resulted in reliable and valid measures of pros and self-efficacy for HPV vaccination that can be used in future clinical research.

    Is consumption of sugar-sweetened beverages (SSB) associated with semen quality? Higher consumption of SSB was associated with lower sperm motility among healthy, young men. The existing literature on the potential role of SSBs on male reproductive function is scarce and primarily focused on the relation between caffeinated beverages and semen quality. However, a rodent model suggests that SSBs may hamper male fertility. The Rochester Young Men's Study; a cross-sectional study of 189 healthy young men carried out at the University of Rochester during 2009-2010. Men aged 18-22 years provided semen and blood samples, underwent a physical examination and completed a previously validated food frequency questionnaire (FFQ). Linear regression was used to analyze the association of SSBs with sperm parameters and reproductive hormone levels while adjusting for potential confounders. SSB intake was inversely related to progressive sperm motility. Men in the highest quartile of SSB intake (≥1.3 serving/day) had 9.8 (95% CI: 1.9,17.8) percentage units lower progressive sperm motility than men in the lowest quartile of intake (beverages. While our findings are in agreement with recent experimental data in rodents, more studies are required to draw conclusions on the relation of SSB with semen quality or male infertility.

    HIV infection among men who have sex with men, particularly in Thai urban settings and among younger cohorts, is escalating. HIV testing and counseling (HTC) are important for prevention and obtaining treatment and care. We examine data from a 2013 survey of males, 15-24 years, reporting past-year sex with a male and living in Bangkok or Chiang Mai. Almost three quarters of young MSM (YMSM) in Bangkok and only 27 % in Chiang Mai had an HIV test in the previous year. Associations for HIV testing varied between cities, although having employment increased the odds of HIV testing for both cities. In Bangkok, family knowledge of same sex attraction and talking to parents/guardians about HIV/AIDS had higher odds of HIV testing. Expanded HTC coverage is needed for YMSM in Chiang Mai. All health centers providing HTC, including those targeting MSM, need to address the specific needs of younger cohorts.

    Abstract Purpose: To develop optimal methods to study sexual health among black young men who have sex with men and transgender women (BYMSM/TW). Methods: We conducted a mixed-methods prospective study to identify recruitment and retention strategies for BYMSM/TW (age 16–21) in Washington D.C., and describe HIV risk behaviors and context. Results: Incentivized peer referral was highly productive, and 60% of BYMSM/TW were retained for 3 months. Participants reported high levels of sexual risk, homophobia, racism, and maternal support. Conclusion: BYMSM/TW studies should utilize a combination of peer-based, in-person, and technology-based recruiting strategies. Additional research is needed to leverage mobile technology and social media to enhance retention. PMID:26651365

    The goal of this study was to identify strategies that could yield more inclusive church-based HIV prevention efforts. In-depth interviews were conducted with 30 young Black men who have sex with men (YBMSM) living in Baltimore, Maryland. The sample had an equal number of regular and infrequent church attendees. Nearly one-fourth of the sample was HIV-positive. Interviews were transcribed verbatim and analyzed inductively using a qualitative content analytic approach. Two main recommendations emerged for churches to offer more inclusive HIV prevention efforts: (1) reduce homosexuality stigma by increasing interpersonal and institutional acceptance, and (2) address the sexual health needs of all congregants by offering universal and targeted sexual health promotion. Thus, results support a tiered approached to providing more inclusive church-based HIV prevention efforts. We conclude that Black churches can be a critical access point for HIV prevention among YBMSM and represent an important setting to intervene. PMID:27244189

    An initial sample of 120 healthy young men was screened by a personality questionnaire and 15 subjects each with highest and lowest scores respectively on emotionality (emotionally labile, EL subjects and emotionally stable, ES subjects) were recruited for a study on the relationship between the degree of emotionality and the basal secretion of stress-sensitive hormones during night-time. The nocturnal urinary excretion of cortisol, testosterone, adrenaline, noradrenaline and melatonin was measured over a period of 5 consecutive nights. The average amounts of each hormone excreted per night were not different between the two extreme groups. The variability of the excretion during the 5 nights of cortisol and testosterone, but not of adrenaline, noradrenaline and melatonin, was significantly higher in EL compared to ES subjects. The larger fluctuations in the nocturnal secretion of these two (and no other) hormones in EL subjects indicate that emotional lability is associated with a more labile regulation of cortisol and testosterone secretion. The observed intraindividual variability of basal stress hormone secretion may contribute to the vast interindividual variability noticed in psychoneuroendocrine stress research, especially in emotionally labile subjects.

    Full Text Available Emerging evidence suggests that dietary fats may influence testicular function. However, most of the published literature on this field has used semen quality parameters as the only proxy for testicular function. We examined the association of fat intake with circulating reproductive hormone levels and testicular volume among healthy young Spanish men. This is a cross-sectional study among 209 healthy male volunteers conducted between October 2010 and November 2011 in Murcia Region of Spain. Participants completed questionnaires on lifestyle, diet, and smoking, and each underwent a physical examination, and provided a blood sample. Linear regression was used to examine the association between each fatty acid type and reproductive hormone levels and testicular volumes. Monounsaturated fatty acids intake was inversely associated with serum blood levels of calculated free testosterone, total testosterone, and inhibin B. A positive association was observed between the intake of polyunsaturated fatty acids, particularly of omega-6 polyunsaturated fatty acids, and luteinizing hormone concentrations. In addition, the intake of trans fatty acids was associated with lower total testosterone and calculated free testosterone concentrations (P trend = 0.01 and 0.02, respectively. The intake of omega-3 polyunsaturated fatty acids was positively related to testicular volume while the intake of omega-6 polyunsaturated fatty acids and trans fatty acids was inversely related to testicular volume. These data suggest that fat intake, and particularly intake of omega 3, omega 6, and trans fatty acids, may influence testicular function.

    Religiosity and spirituality are often integral facets of human development. Young gay and bisexual men (YGBM), however, may find themselves at odds when attempting to reconcile potentially conflicting identities like religion and their sexual orientation. We sought to explore how different components of religiosity (participation, commitment, spiritual coping) are linked to different markers of psychological well-being (life purpose, self-esteem, and internalized homophobia). Using data collected in Metro Detroit (N = 351 ages 18-29 years; 47% African American, 29% Non-Latino White, 8% Latino, 16% Other Race), we examined how components of religiosity/spirituality were associated with psychological well-being among religious/spiritual-identified participants. An overwhelming majority (79.5%) identified as religious/spiritual, with most YGBM (91.0%) reporting spirituality as a coping source. Over three quarters of our religious/spiritual sample (77.7%) reported attending a religious service in the past year. Religious participation and commitment were negatively associated with psychological well-being. Conversely, spiritual coping was positively associated with YGBM's psychological well-being. Programs assisting YGBM navigate multiple/conflicting identities through sexuality-affirming resources may aid improve of their psychological well-being. We discuss the public health potential of increasing sensitivity to the religious/spiritual needs of YGBM across social service organizations.

    Full Text Available ABSTRACT Introduction: Birth weight has been considered an important marker of the nutritional transition in developing countries. Objective: To evaluate the influence of birth weight on body composition and physical fitness of young men born in Maputo, Mozambique. Methods: One hundred and seventy-nine students (aged 19 to 22 years were divided into four groups (low birth weight 3.999 g, HBW, n = 31. Anthropometry and body composition were measured. Physical fitness was assessed by handgrip strength, muscle endurance, flexibility, agility, and running speed. Results: IBW showed lower values of body mass and fat free mass while LBW and HBW had high values of hip circumference, suprailiac, subscapular and abdominal skinfold when compared to NBW. LBW and HBW showed a high percentage of individuals with low performance in flexibility, right handgrip, agility, abdominal resistance, arms strength, and horizontal long jump. Around 70% of HBW showed low performance in the running speed test. Conclusion: Both low and high birth weight can influence adult adiposity and the performance in physical fitness tests.

    Arterial stiffness increases after glucose ingestion. Acute low- and moderate-intensity aerobic exercise decreases arterial stiffness. However, the acute effects of 30 min of cycling at low- and moderate-intensity [25% (LE trial) and 65% (ME trial) peak oxygen uptake, respectively] on arterial stiffness at 30, 60 and 120 min of a postexercise glucose ingestion. Ten healthy young men (age, 22·4 ± 0·5 years) performed LE and ME trials on separate days in a randomized controlled crossover fashion. Carotid-femoral (aortic) pulse wave velocity (PWV), femoral-ankle (leg) PWV, carotid augmentation index (AIx) and carotid blood pressure (BP) (applanation tonometry), brachial and ankle BP (oscillometric device), heart rate (HR) (electrocardiography), blood glucose (UV-hexokinase method) and blood insulin (CLEIA method) levels were measured at before (baseline) and at 30, 60 and 120 min after the 75-g OGTT. Leg PWV, ankle pulse pressure and BG levels significantly increased from baseline after the 75-g OGTT in the LE trial (P<0·05), but not in the ME trial. Insulin levels and HR significantly increased from baseline after the 75-g OGTT in both trials (P<0·05). Aortic PWV, carotid AIx, brachial BP and carotid BP did not change from baseline after the 75-g OGTT in both trials. The present findings indicate that aerobic exercise at moderate intensity before glucose ingestion suppresses increases leg arterial stiffness after glucose ingestion.

    Sleep deprivation is known to suppress circulating trophic factors such as insulin-like growth factor (IGF)-I and brain-derived neurotrophic factor (BDNF). This experiment examined the effect of an intervention involving 6 nights of extended sleep before total sleep deprivation on this catabolic profile. In a randomized crossover design, 14 young men (age range: 26-37 years) were either in an extended (EXT; time in bed: 2100-0700 h) or habitual (HAB: 2230-0700 h) sleep condition, followed by 3 days in the laboratory with blood sampling at baseline (B), after 24 h of sleep deprivation (24h-SD), and after 1 night of recovery sleep (R). In the EXT condition compared with the HAB condition, free IGF-I levels were significantly higher at B, 24h-SD, and R (P sleep deprivation was for insulin levels, which were significantly higher after R compared with B. In a healthy adult, additional sleep over 1 week increased blood concentrations of the anabolic factor IGF-I before and during 24 h of sleep deprivation and after the subsequent recovery night without effects on BDNF. With further research, these findings may prove to be important in guiding effective lifestyle modifications to limit physical or cognitive deficits associated with IGF-I decrease with age.

    The distribution of delta activity across successive nonrapid eye movement (NREM) sleep episodes and its night-to-night stability across three consecutive nights were investigated by studying delta power with spectral analysis in 31 healthy young men. Repeated-measures analysis of variance (ANOVA) with polynomial contrast was applied to grouped data of absolute delta power and three indexes: (1) the rate of delta power per NREM episode to its duration, 2) the standardized rate for the last NREM episode, and 3) the logarithm of the standardized rate. A significant linear decrease across NREM episodes was observed for each variable in each successive night. In addition, using night as a second within-subjects factor, no night effect was observed. Yet, the subsequent analysis of the logarithmic data yielded greater F values in all three nights' data as well as a linear function that accounted for a greater proportion of total variance than the analysis of the nonlogarithmic data. Since a linear decline for the logarithm of a variable implies an exponential distribution for that variable, we conclude that delta activity is distributed exponentially across NREM episodes, and this finding shows a remarkable night-to-night stability.

    The aim of this cross-sectional study was to concurrently assess musculo-articular stiffness (MAS) and muscle stiffness (MS) of the knee extensors in younger and older individuals. Fourteen young (22.1 ± 3.0 years old) and 12 older (65.4 ± 5.7 years old) men were tested for maximal voluntary contraction (MVC), rate of torque development (RTD), muscle thickness, MAS, and MS of knee extensors. MVC, RTD, and muscle thickness were higher in the younger group (288.6 vs. 194.3 Nm, 1319.5 vs. 787.0 Nm s(-1), 23.1 vs. 17.7 mm, respectively, P < 0.05). MAS normalized to the load supported (30% of MVC) was not different between groups (87.9 vs. 88.5 Nm(-1) kg(-1)), whereas the older group exhibited a higher level of normalized MS (23.2 vs. 18.6 Nm(-1) kg(-1), P < 0.05). Determinants of MS have been highlighted along with their role in elevated MS. The unaltered level of MAS, which is functionally important in an aging population, might be achieved through a decrease in tendon stiffness. Copyright © 2012 Wiley Periodicals, Inc.

    The aim of this prospective study was to identify relevant determinants of young gay and bisexual men's (YGBM) condom use when having anal sex with casual partners. Respondents (185 YGBM in the midst of their coming-out; mean age 18.9 years) completed an online questionnaire on social-cognitive determinants of condoms use derived from the theory of planned behavior (Ajzen, 1991) at Wave 1. At six months follow-up (Wave 2) sexual behavior with casual partners was assessed. A total of 63 YGBM reported sex with a casual partner in the six months between Waves 1 and 2, of whom 49% (N=31) had anal sex. Of the YGBM who had anal sex, 42% (N=13) had unprotected anal sex. Condom use with casual partners was best predicted by the intention to always use condoms. Furthermore, attitude, descriptive and personal norms, and perceived control significantly predicted intention to always use condoms. Interventions, targeting YGBM, aiming to promote condom use with casual partners should focus on increasing attitudes and strengthening skills to negotiate and use condoms.

    Lack of donor organs remains a major obstacle in organ transplantation. Our aim was to evaluate (1) the association between engaging in high-risk recreational activities and attitudes toward organ donation and (2) the degree of reciprocity between organ acceptance and donation willingness in young men. A 17-item, close-ended survey was offered to male conscripts ages 18 to 26 years in all Swiss military conscription centers. Predictors of organ donation attitudes were assessed in bivariate analyses and multiple logistic regression. Reciprocity of the intentions to accept and to donate organs was assessed by means of donor card status. In 1559 responses analyzed, neither motorcycling nor practicing extreme sports reached significant association with donor card holder status. Family communication about organ donation, student, or academic profession and living in a Latin linguistic region were predictors of positive organ donation attitudes, whereas residence in a German-speaking region and practicing any religion predicted reluctance. Significantly more respondents were willing to accept than to donate organs, especially among those without family communication concerning organ donation. For the first time, it was shown that high-risk recreational activities do not influence organ donation attitudes. Second, a considerable discrepancy in organ donation reciprocity was identified. We propose that increasing this reciprocity could eventually increase organ donation rates. Copyright © 2015 Elsevier Inc. All rights reserved.

    Little research has been reported on the effects of using different devices with resistance exercises in a water environment. This study compared muscular activation of lower extremity and core muscles during leg adduction performed at maximum velocity with drag and floating devices of different sizes. A total of 24 young men (mean age 23.20 ± 1.18 years) performed 3 repetitions of leg adduction at maximum velocity using 4 different devices (ie, large/small and drag/floating). The maximum amplitude of the electromyographic root mean square of the adductor longus, rectus abdominis, external oblique on the dominant side, external oblique on the nondominant side, and erector lumbar spinae were recorded. Electromyographic signals were normalized to the maximum voluntary isometric contraction (MVIC). Unexpectedly, no significant (P > 0.05) differences were found in the neuromuscular responses among the different devices used; the average activation of agonist muscle adequate for neuromuscular conditioning was 40.95% of MVIC. In addition, external oblique activation is greater on the contralateral side to stabilize the body (average, 151.74%; P < 0.05). Therefore, if maximum muscle activation is required, the kind of device is not relevant. Thus, the choice should be based on economic factors.

    Full Text Available Music and high levels of sound have not traditionally been associated with risk-taking behaviors. Loud music may intensify and bring more power and meaning to the musical experience, but it can at the same time be harmful to hearing. The present study aims to increase the knowledge about young women′s and men′s risk judgement and behaviour by investigating patterns in adolescent risk activities among 310 adolescents aged 15-20 (143 women; 167 men. The Australian instrument ARQ was used with additional questions on hearing risks and a factor analysis was conducted. The main results showed that the factor structure in the judgement and behavior scale for Swedish adolescents was rather different from the factor structure in the Australian sample. Also, the factor structure was not similar to the Australian sample split on gender. The results are discussed from a gender- and existential perspective on risk taking, and it is emphasized that research on risk behavior needs to reconceptualize stereotypical ideas about gender and the existential period in adolescence.

    This mixed-methods study was designed to explore young Australian men's attitudes and behaviour in relation to mental health and technology use to inform the development of online mental health services for young men. National online survey of 486 males (aged 16 to 24) and 17 focus groups involving 118 males (aged 16 to 24). Young men are heavy users of technology, particularly when it comes to entertainment and connecting with friends, but they are also using technology for finding information and support. The focus group data suggested that young men would be less likely to seek professional help for themselves, citing a preference for self-help and action-oriented strategies instead. Most survey participants reported that they have sought help for a problem online and were satisfied with the help they received. Focus group participants identified potential strategies for how technology could be used to overcome the barriers to help-seeking for young men. The key challenge for online mental health services is to design interventions specifically for young men that are action-based, focus on shifting behaviour and stigma, and are not simply about increasing mental health knowledge. Furthermore, such interventions should be user-driven, informed by young men's views and everyday technology practices, and leverage the influence of peers.

    For several decades, diagnoses of genital warts at genitourinary medicine (GUM) clinics in England had been increasing. In 2008, a national human papillomavirus (HPV) vaccination programme was introduced using the bivalent vaccine (types 16 and 18 only). A decrease in genital warts was not anticipated. However, rates of genital warts in GUM clinics have declined significantly since the introduction of the vaccine. Using data from GUM clinics across England, we analysed rates of genital warts by age, gender, sexual orientation and estimated vaccine coverage. The reduction in rates of genital warts diagnoses at GUM clinics between 2009 and 2014 was 30.6% among young women aged 15-19 years and 25.4% among same age heterosexual young men. Overall there was an association showing higher warts reduction with increasing vaccination coverage with the largest declines in warts diagnoses observed in young women aged 15 years (50.9%) with the highest vaccination coverage. No such declines were observed in men who have sex with men (MSM) of the same age. The results of these ecological analyses are strongly in keeping with the bivalent HPV vaccine providing modest protection against genital warts. Published by the BMJ Publishing Group Limited.

    Irisin, a newly discovered, PGC-1α dependent myokine, has recently been shown to increase in circulation in response to sprint exercise. This study examined the effect of prolonged exercise on irisin concentrations in young men (n=7) as well as in young women (n=5) during different stages of the menstrual cycle. Seven young men completed 90 min of treadmill exercise at 60% of VO2max and a resting control trial. Five women completed the same exercise protocol in two different trials: during the early follicular phase and mid-luteal phase of the menstrual cycle. Blood samples were collected and analyzed for irisin concentrations immediately before exercise, at 54 and 90 min of exercise, and at 20 min of recovery (R20). Findings revealed that by 54 min of a 90 min treadmill exercise protocol at 60% of VO2max, irisin concentrations significantly increased 20.4% in young men and 20.3% as well as 24.6% in young women during the early follicular and mid-luteal phases of the menstrual cycle, respectively. However, by 90 min of exercise as well as R20, irisin concentrations were no longer elevated. Stage of the menstrual cycle did not affect responses in young women. Findings indicate that prolonged aerobic exercise produces a transient increase in irisin concentrations during the first hour of exercise for both genders and suggest that this form of moderate exercise may be helpful in improving fat metabolism.

    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 Background Based on the research evidence, the efficiency of resistance exercises depends on the changes in the hormones level to improve the muscle strength and mass. Objectives This study aimed to investigate the effect of a short course blood flow restricted resistance training on serum cortisol and testosterone levels in young men. Patients and Methods A total of 30 healthy young men (aged 19 - 24 years were volunteered for this study. Subjects were randomly assigned into three groups: low-intensity blood flow restricted (LIBFR (n = 15 resistance exercise group (3 sets of 15 repetitions at 20% of 1RM (one repetition maximum, traditional high-intensity without blood flow restriction (HIWBFR (n = 12 resistance exercise group (3 sets of 10 repetitions at 80% of 1RM, and a control group (n = 13. Both LIBFR and HIWBFR groups trained for front leg and squat exercises 3 days per week for 3 weeks. Fasting growth hormone cortisol and testosterone levels were measured in the morning before and after exercise sessions. Data were analyzed with paired t-test and One-way ANOVA at the significant level of P < 0.05. Results Serum cortisol level significantly increased after the exercise for both protocols compared to baseline (P < 0.05. After 3 weeks, serum cortisol level increased significantly in LIBFR and HIWBFR groups compared to control group (P < 0.001. At the end of the exercise protocols, serum testosterone level was higher in LIBFR group compared to HIWBFR group; however, this difference was not significant (P ˃ 0.49. Conclusions Short term blood flow restriction (BFR exercise stimulates cortisol hormones production in young men. However, this program seems too short to express any difference in testosterone change. Generally, it can be concluded that low-intensity resistance training can increase short-term BFR catabolic-anabolic hormones in young men.

    Full Text Available Background: Young men are difficult to reach with conventional nutrition information and they have a low intake of vegetables and whole grain cereals. Few intervention studies have focused on improving young men's consumption of vegetables and whole grains. Objective: A 5-month intervention focusing on a combination of increased availability of healthy foods and nutritional information was developed to stimulate the intake of vegetables and semi-whole grain bread among a group of young men in the Norwegian military. Subjects: A total of 376 recruits in the intervention group and 105 recruits in the control group participated in the entire study. Results: The average daily increase in consumption of vegetables was 82 g (p<0.001, and semi-whole grain bread 47 g (p<0.001 between baseline and follow-up in the intervention group. No significant changes were observed in the control group. Differences between intervention and control group at follow-up were significant (p<0.001 for vegetables and semi-whole grain bread, when controlling for baseline values, and seasonal variation for vegetables. The recruits in the intervention group received higher scores on the questions concerning nutritional knowledge after the intervention, compared to baseline (p<0.001. There was a significantly higher increase in the intake of vegetables among the recruits who increased the number of correct answers to the knowledge questions (β-value: 0.14, p<0.05 than among the others. There was no significant change in scores of food satisfaction after the intervention. Conclusion: The combination of increased availability of healthy food items and nutrition information was an effective way to increase the intake of vegetables and semi-whole grain bread, without a reduction in food satisfaction, among young men in the military.

    INTRODUCTION: We examined the association between cognitive ability in young adulthood and dementia in Danish men, brothers, and male twins. METHODS: In total, 666,986 men born between 1939 and 1959 were identified for dementia diagnosis in national registries from 1969 to 2016. The association...... between cognitive ability from draft board examination and dementia was examined using Cox regression. RESULTS: During a 44-year follow-up, 6416 (0.96%) men developed dementia, 1760 (0.26%) and 970 (0.15%) of which were classified as Alzheimer's and vascular dementia, respectively. Low cognitive ability...... was associated with increased risk of dementia (hazard ratio [HR]per SD decrease 1.33 [95% confidence interval {CI} = 1.30-1.35]) with the strongest associations for vascular dementia (HRper SD decrease 1.47 [95% CI = 1.31-1.56]) and a weaker for Alzheimer's disease (HRper SD decrease 1.07 [95% CI = 1...

    The underlying factors related to the divergent findings of age-related fatigue for dynamic tasks are not well understood. The purpose here was to investigate age-related fatigability and recovery between a repeated constrained (isokinetic) and an unconstrained velocity (isotonic) task, in which participants performed fatiguing contractions at the velocity (isokinetic) or resistance (isotonic) corresponding with maximal power. To compare between tasks, isotonic torque-power relationships were constructed prior to and following both fatiguing tasks and during short-term recovery. Contractile properties were recorded from 9 old (~75 years) and 11 young (~25 years) men during three testing sessions. In the first session, maximal power was assessed, and sessions 2 and 3 involved an isokinetic or an isotonic concentric fatigue task performed until maximal power was reduced by 40 %. Compared with young, the older men performed the same number of contractions to task failure for the isokinetic task (~45 contractions), but 20 % fewer for the isotonic task (p contraction strength, angular velocity, and power were reduced by ~30, ~13, and ~25 %, respectively, immediately following task failure, and only isometric torque was not recovered fully by 10 min. In conclusion, older men are more fatigable than the young when performing a repetitive maximal dynamic task at a relative resistance (isotonic) but not an absolute velocity (isokinetic), corresponding to maximal power.

  9. Effects of Single Vs. Multiple Sets Water-Based Resistance Training on Maximal Dynamic Strength in Young Men

    2015-09-01

    Full Text Available The aim of this study was to compare the effects of single vs. multiple sets water-based resistance training on maximal dynamic strength in young men. Twenty-one physically active young men were randomly allocated into 2 groups: a single set group (SS, n=10 and a multiple sets group (MS, n=11. The single set program consisted of only 1 set of 30 s, whereas the multiple sets comprised 3 sets of 30 s (rest interval between sets equaled 1 min 30 s. All the water-based resistance exercises were performed at maximal effort and both groups trained twice a week for 10 weeks. Upper (bilateral elbow flexors and bilateral elbow extensors, peck deck and inverse peck deck as well as lower-body (bilateral knee flexors and unilateral knee extensors one-repetition maximal tests (1RM were used to assess changes in muscle strength. The training-related effects were assessed using repeated measures two-way ANOVA (α=5%. Both SS and MS groups increased the upper and lower-body 1RM, with no differences between groups. Therefore, these data show that the maximal dynamic strength significantly increases in young men after 10 weeks of training in an aquatic environment, although the improvement in the strength levels is independent of the number of sets performed.

    Full Text Available BACKGROUND: Methamphetamine (MA is a new arrival to the Southeastern United States (US. Incidence of HIV is also increasing regionally, but data are limited regarding any association between this trend and MA use. We examined behavioral data from North Carolina (NC residents newly diagnosed with HIV, collected by the Department of Health between 2000-2005. PRINCIPAL FINDINGS: Among 1,460 newly diagnosed HIV-positive young men, an increasing trend was seen from 2000-2005 in MA use (p = 0.01, total n = 20. In bivariate analyses, users of MA had significantly greater odds of reporting other substance use, including alcohol, powder or crack cocaine, marijuana, and methylenedioxymethamphetamine (MDMA, "ecstasy". They were also more likely to have reported sexual activity while traveling outside NC; sex with anonymous partners; and previous HIV testing. In a predictive model, MA use had a negative association with nonwhite race, and strong positive associations with powder cocaine, "ecstasy," or intravenous drug use and being a university student. CONCLUSIONS: Similar to trends seen in more urban parts of the US, MA use among newly diagnosed, HIV-positive young men is increasing in NC. These data are among the first to demonstrate this relationship in a region with a burgeoning epidemic of MA use. Opportunities exist for MA-related HIV risk-reduction interventions whenever young men intersect the healthcare system.

    2008-10-01

    This paper examines cultural and social meanings associated with semen, along with related issues of unprotected receptive anal intercourse, HIV seroconversion, treatment optimism and viraemia. The findings are derived from qualitative interviews conducted with 12 HIV-positive young gay men and 12 HIV-negative counterparts who participated in a prospective cohort study in Vancouver, Canada. Focussing on the narratives of young gay men, the analysis reveals a diverse range of knowledge, values and functions of semen, especially in relation to its exchange. Beliefs about semen appeared to differ by HIV serostatus and were linked with intimacy, identity and pleasure, particularly among the HIV-positive men. Against dominant representations of semen in relation to issues of loss, anxiety and infertility, this unique study sheds much needed light on its role within the cultural construction of sexuality among gay men. As such, these narratives are of direct importance to primary and secondary HIV prevention, including condom promotion and the development of rectal microbicides.

    This study sought to assess the association between traditional masculine gender role ideologies and sexual risk and intimate partner violence (IPV) perpetration behaviors in young men's heterosexual relationships. Sexually active men age 18-35 years attending an urban community health center in Boston were invited to join a study on men's sexual risk; participants (N=307) completed a brief self-administered survey on sexual risk (unprotected sex, forced unprotected sex, multiple sex partners) and IPV perpetration (physical, sexual and injury from/need for medical services due to IPV) behaviors, as well as demographics. Current analyses included men reporting sex with a main female partner in the past 3 months (n=283). Logistic regression analyses adjusted for demographics were used to assess significant associations between male gender role ideologies and the sexual risk and IPV perpetration behaviors. Participants were predominantly Hispanic (74.9%) and Black (21.9%); 55.5% were not born in the continental U.S.; 65% had been in the relationship for more than 1 year. Men reporting more traditional ideologies were significantly more likely to report unprotected vaginal sex in the past 3 months (OR(adj) = 2.3, 95% CI = 1.2-4.6) and IPV perpetration in the past year (OR(adj) = 2.1, 95% CI = 1.2-3.6). Findings indicate that masculine gender role ideologies are linked with young men's unprotected vaginal sex and IPV perpetration in relationships, suggesting that such ideologies may be a useful point of sexual risk reduction and IPV prevention intervention with this population.

    We investigated whether there were racial/ethnic differences among young men who have sex with men (MSM) in their use of, perceived importance of, receipt of, and satisfaction with HIV prevention services received at health care providers (HCP) and HIV test providers (HTP) that explain racial disparities in HIV prevalence. Young men, aged 23 to 29 years, were interviewed and tested for HIV at randomly sampled MSM-identified venues in six U.S. cities from 1998 through 2000. Analyses were restricted to five U.S. cities that enrolled 50 or more black or Hispanic MSM. Among the 2,424 MSM enrolled, 1,522 (63%) reported using a HCP, and 1,268 (52%) reported having had an HIV test in the year prior to our interview. No racial/ethnic differences were found in using a HCP or testing for HIV. Compared with white MSM, black and Hispanic MSM were more likely to believe that HIV prevention services are important [respectively, AOR, 95% confidence interval (CI): 3.0, 1.97 to 4.51 and AOR, 95% CI: 2.7, 1.89 to 3.79], and were more likely to receive prevention services at their HCP (AOR, 95% CI: 2.5, 1.72 to 3.71 and AOR, 95% CI: 1.7, 1.18 to 2.41) and as likely to receive counseling services at their HTP. Blacks were more likely to be satisfied with the prevention services received at their HCP (AOR, 95% CI: 1.7, 1.14 to 2.65). Compared to white MSM, black and Hispanic MSM had equal or greater use of, perceived importance of, receipt of, and satisfaction with HIV prevention services. Differential experience with HIV prevention services does not explain the higher HIV prevalence among black and Hispanic MSM.

Eight recreationally active males (aged 22±2 years performed 2 weeks of HIIT on a cycle ergometer (six HIIT sessions at 8–12 intervals; 60-second intervals, 75-second active rest at a power output equivalent to 100% of their predetermined peak oxygen uptake (VO2max. Serum samples were collected during the first and sixth HIIT sessions at rest and immediately, 15, 30, and 45 minutes post-exercise. An acute session of HIIT induced significant increases in interleukin (IL-6, IL-8, IL-10, tumor necrosis factor-α, and monocyte chemotactic protein-1 compared with rest. The concentrations of interferon-γ, granulocyte macrophage-colony-stimulating factor, and IL-1β were unaltered with an acute session of HIIT. Two weeks of training did not alter the inflammatory response to an acute bout of HIIT exercise. Maximal power achieved during a VO2max test significantly increased 4.6%, despite no improvements in VO2max after 2 weeks of HIIT. These data suggest that HIIT exercise induces a small inflammatory response in young, recreationally active men; however, 2 weeks of HIIT does not alter this response.

    Our previous study demonstrated that a single bout of stretching exercises acutely reduced arterial stiffness. We hypothesized that this acute vascular response is due to regional mechanical stimulation of the peripheral arteries. To test this hypothesis, we examined the effect of a single bout of passive one leg stretching on arterial stiffness, comparing the stretched and the non-stretched leg in the same subject. Twenty-five healthy young men (20.9 ± 0.3 years, 172.5 ± 1.4 cm, 64.1 ± 1.2 kg) volunteered for the study. Subjects underwent a passive calf stretching on one leg (six repetitions of 30-s static stretch with a 10-s recovery). Pulse wave velocity (PWV, an index of arterial stiffness), blood pressure (BP), and heart rate (HR) were measured before and immediately, 15, and 30 min after the stretching. Femoral-ankle PWV (faPWV) in the stretched leg was significantly decreased from baseline (835.0 ± 15.9 cm/s) to immediately (802.9 ± 16.8 cm/s, P stretching, despite no changes in systolic and diastolic BP, or HR. However, faPWV in the non-stretched leg was not significantly altered at any time. Brachial-ankle PWV (baPWV) also showed similar responses with faPWV, but this response was not significant. Additionally, the passive stretching did not alter carotid-femoral PWV (cfPWV). These results suggest that mechanical stimulation to peripheral arteries as induced by static passive stretch may modulate arterial wall properties directly, rather than resulting in a systemic effect.

    Naczk, M, Naczk, A, Brzenczek-Owczarzak, W, Arlet, J, and Adach, Z. Impact of inertial training on strength and power performance in young active men. J Strength Cond Res 30(8): 2107-2113, 2016-This study evaluated how 5 weeks of inertial training using 2 different loads influenced strength and power performance. Fifty-eight male physical education students were randomly divided into training and control groups. The 2 training groups (T0 and T10) performed inertial training 3 times per week for 5 weeks using the new Inertial Training and Measurement System (ITMS). Each training session included 3 exercise sets involving the knee extensors muscles. The T0 group used only the mass of the ITMS flywheel (19.4 kg), whereas the T10 group had an additional 10 kg on the flywheel. Before and after training, we evaluated maximum force and power of knee extensors muscles, countermovement jump (CMJ), squat jump (SJ), maximal power output achieved during ergometer test PVT, electromyography of quadriceps, and muscle mass. In T0 and T10, respectively, ITMS training induced significant increases in muscle force (25.2 and 23.3%), muscle power (33.2 and 27%), CMJ (3.8 and 6.7%), SJ (2.2 and 6.1%), PVT (8 and 7.4%), and muscle mass (9.8 and 15%). The changes did not significantly differ between T0 and T10. A 16% significant increase of electromyography amplitude (quadriceps muscle) was noted only in T0. The novel ITMS training method is effective for improving muscular strength and power. Improvements in PVT, CMJ, and SJ indicate that the increased strength and power elicited by ITMS training can translate to improvements in sport performance. The ITMS training can also be useful for building muscle mass.

    Peer pressure (PP) has been shown to play a major role in the development and continuation of alcohol use and misuse. To date, almost all the studies investigating the association of PP with alcohol use only considered the PP for misconduct but largely ignored other aspects of PP, such as pressure for peer involvement and peer conformity. Moreover, it is not clear whether the association of PP with alcohol use is direct or mediated by other factors. The aim of the present study was to investigate the association of different aspects of peer pressure (PP) with drinking volume (DV) and risky single-occasion drinking (RSOD), and to explore whether these associations were mediated by drinking motives (DM). A representative sample of 5521 young Swiss men, aged around 20 years old, completed a questionnaire assessing their usual weekly DV, the frequency of RSOD, DM (i.e. enhancement, social, coping, and conformity motives), and 3 aspects of PP (i.e. misconduct, peer involvement, and peer conformity). Associations between PP and alcohol outcomes (DV and RSOD) as well as the mediation of DM were tested using structural equation models. Peer pressure to misconduct was associated with more alcohol use, whereas peer involvement and peer conformity were associated with less alcohol use. Associations of drinking outcomes with PP to misconduct and peer involvement were partially mediated by enhancement and coping motives, while the association with peer conformity was partially mediated by enhancement and conformity motives. Results suggest that PP to misconduct constitutes a risk factor, while peer conformity and peer involvement reflect protective factors with regard to alcohol use. Moreover, results from the mediation analyses suggest that part of the association of PP with alcohol use came indirectly through DM: PP was associated with DM, which in turn were associated with alcohol use.

    Full Text Available Aim. To evaluate effect of bisoprolol on circadian blood pressure (BP profile, autonomic cardiovascular regulation, lipid and carbohydrate metabolism in young patients with arterial hypertension (HT and obesity. Materials and methods. 36 men aged 18 to 35 years with HT 1-2 degrees, obesity 1-2 degrees and signs of sympathetic over activity were examined. In addition to standard clinical examination assessment of heart rate variability (HRV during orthostatic test with spectral analysis, ambulatory BP monitoring, evaluation of lipid profile, oral glucose tolerance test, determination of immunoreactive insulin, insulin resistance index and functional activity of beta-cells were performed. Anthropometric measurements included body mass index and waist circumference. Bisoprolol in the initial dose of 5 mg QD orally for 12 weeks was assigned to all patients. After 12 weeks of bisoprolol treatment repeated examination was performed. Results. Significant changes in HRV after 12 weeks of treatment with bisoprolol was found. Parasympathetic influence of autonomic nervous system increased during orthostatic test. Contribution of the slow and very slow waves, which reflect sympathetic and neurohumoral activity , reduced. Total spectral power was significantly increased. Initial tachycardia reduced. Target BP values were achieved after 12 weeks of treatment with bisoprolol 5 mg QD. Increase in a number of dippers and decrease in a number of nondippers in terms of both systolic and diastolic BP was observed. Heart rate and HRV was significantly decreased. No adverse events in terms of lipid or carbohydrate metabolism were found during treatment with bisoprolol. Conclusion. Bisoprolol 12 week treatment resulted in sympathetic activity decrease and parasympathetic activity increase, achievement of BP target levels, improvement of BP circadian profile. Bisoprolol therapy in dose of 5 mg/day demonstrated metabolic neutrality in patients with risk factors of

    A lifetime history of alcohol dependence has been associated with elevations in neuroticism in Mexican American young adults. The identification of genetic markers associated with neuroticism and their influence on the development of alcohol use disorders (AUD) may contribute to our understanding of the relationship between personality traits and the increased risk of AUD in Mexican Americans. The purpose of this study was to investigate associations between neuroticism and 13 single nucleotide polymorphisms (SNPs) in the nicotinic acetylcholine (nAChR) α5-subunit (CHRNA5) and α3-subunit (CHRNA3) genes in young adult Mexican American men and women. Participants were 465 young adult Mexican American men and women who are literate in English and are residing legally in San Diego County. Each participant gave a blood sample and completed a structured diagnostic interview. Neuroticism was assessed using the Maudsley Personality Inventory. The minor alleles of four CHRNA5 polymorphisms (rs588765, rs601079, rs680244 and rs555018) and three CHRNA3 polymorphisms (rs578776, rs6495307 and rs3743078) showed associations with neuroticism. Several of these SNPs also displayed nominal associations with DSM-IV alcohol and nicotine dependence, but tests of mediation suggested that these relations could be partially explained by the presence of co-occurring neuroticism. These findings suggest that genetic variations in nicotinic receptor genes may influence the development of neuroticism, which in turn is involved in the development of AUDs and nicotine dependence in Mexican American young adults.

    Very little information exists with regard to sex party behaviors in young men who have sex with men (YMSM), often defined as men ranging in age from 13 to 29 years. The current analysis examines sex party attendance and behavior in a sample of 540 emergent adult gay, bisexual, and other YMSM in New York City, ages 18-29 years. Findings indicate that 8.7% (n = 47) of the sample had attended a sex party 3 months prior to assessment. Sex party attendees reported that parties included both HIV-positive and HIV-negative men; attendees also reported unprotected sex and limited access to condoms and lubricant. As compared with those who did not attend sex parties, those who did indicated significantly more lifetime and recent (last 3 months) casual sex partners, drug use (both number of different drugs used and total lifetime use), psychosocial burden (history of partner violence and number of arrests), and total syndemic burden (a composite of unprotected anal sex, drug use and psychosocial burden). These results indicate that while only a small percentage of the overall sample attended sex parties, the intersection of both individual risk factors coupled with risk factors engendered within the sex party environment itself has the potential to be a catalyst in the proliferation of the HIV/AIDS epidemic in urban settings. Lastly, given that sex parties are different than other sex environments, commercial and public, with regard to how they are accessed, public health strategies may need to become more tailored in order to reach this potentially highly risky group.

    Nutritional factors might play a role in regulating serum levels of insulin-like growth factors (IGFs), which are associated with some cancers. We examined the associations of nutritional factors with IGF-1 and IGF binding protein-3 (IGFBP-3). Serum IGF-1 and IGFBP-3 levels and dietary intake were measured in 459 black and 682 white male subjects of the Coronary Artery Risk Development in Young Adults study at the Year 7 (1992-1993) exam. Analysis of covariance and multivariable linear regression were used to assess associations of IGFs with dietary factors by race. IGF-1 was positively associated with magnesium in both black and white men (P = 0.008 and 0.05, respectively). Calcium was positively significantly related to IGF-1 in black men (P = 0.04) and marginally so in white men (P = 0.09). In black men, IGFBP-3 was positively associated with magnesium (P = 0.02), and one serving of milk per day was associated with an 8.23-ng/ml higher IGF-1 concentration (P = 0.05). Tests for interaction, however, revealed no differences between blacks and whites in the associations of nutrients with IGF-1 or IGFBP-3. In conclusion, the associations of dietary factors with serum IGF-1 and IGFBP-3 observed in our study corroborate those from other studies and generally do not differ between black and white men.

    Sexually explicit material (SEM) (including Internet, video, and print) may play a key role in the lives of Black same-sex sexually active youth by providing the only information to learn about sexual development. There is limited school-and/or family-based sex education to serve as models for sexual behaviors for Black youth. We describe the role SEM plays in the sexual development of a sample of Black same-sex attracted (SSA) young adolescent men ages 15–19. Adolescents recruited from clinics, social networking sites, and through snowball sampling were invited to participate in a 90-min, semi-structured qualitative interview. Most participants described using SEM prior to their first same-sex sexual experience. Participants described using SEM primarily for sexual development, including learning about sexual organs and function, the mechanics of same-gender sex, and to negotiate one’s sexual identity. Secondary functions were to determine readiness for sex; to learn about sexual performance, including understanding sexual roles and responsibilities (e.g., “top” or “bottom”); to introduce sexual performance scripts; and to develop models for how sex should feel (e.g., pleasure and pain). Youth also described engaging in sexual behaviors (including condom non-use and/or swallowing ejaculate) that were modeled on SEM. Comprehensive sexuality education programs should be designed to address the unmet needs of young, Black SSA young men, with explicit focus on sexual roles and behaviors that may be inaccurately portrayed and/or involve sexual risk-taking (such as unprotected anal intercourse and swallowing ejaculate) in SEM. This work also calls for development of Internet-based HIV/STI prevention strategies targeting young Black SSA men who maybe accessing SEM. PMID:25677334

    Developing effective place-based health interventions requires understanding of the dynamic between place and health. The therapeutic landscape framework explains how place-based social processes and physical geography interact and influence health behavior. This study applied this framework to examine how venues, or social gathering places, influenced HIV risk behavior among young, urban men in Tanzania. Eighty-three public venues where men aged 15-19 met new sexual partners were identified by community informants in one city ward. The majority (86%) of the venues were called 'camps', social gathering places that had formal leaders and members. Observations were conducted at 23 camps and in-depth interviews were conducted with 36 camp members and 10 camp leaders in 15 purposively selected camps. Geographic and social features of camps were examined to understand their contributions to men's behaviors. Camps were characterized by a geographic space claimed by members, a unique name and a democratic system of leadership and governance. Members were mostly men and socialized daily at their camp. They reported strong social bonds and engaging in health-promoting activities such as playing sports and generating income. Members also engaged in HIV risk behaviors, such as meeting new sexual partners and having sex in or around the camp at night. Some members promoted concurrent sexual partnerships with their friends and resisted camp leaders' efforts to change their sexual risk behavior. We conclude that camps are strategic venues for HIV prevention programs for young Tanzanian men. They served as both protective and risk landscapes, illustrating three domains of the therapeutic landscape framework: the built environment; identities of landscape occupants; and sites for collective efficacy. The framework and data suggest HIV intervention components might augment the protective features of the camps, while changing environmental features to reduce risk.

    Full Text Available Abstract Background Nitrite inhalants ("poppers" are peripheral vasodilators which, since the beginning of the epidemic, have been known to increase risk for acquiring HIV infection among men who have sex with men (MSM. However, few studies in recent years have characterized use. From 1999 to 2004, new HIV diagnoses among MSM in British Columbia increased 78%, prompting us to examine the prevalence and correlates of this modifiable HIV risk factor. Methods Self-administered questionnaires were completed between October 2002 and May 2004 as part of an open cohort study of HIV-seronegative young MSM. We measured nitrite inhalant use during the previous year and use during sexual encounters with casual partners specifically. Correlates of use were identified using odds ratios. Results Among 354 MSM surveyed, 31.6% reported any use during the previous year. Nitrite inhalant use during sexual encounters was reported by 22.9% of men and was strongly associated with having casual partners, with greater numbers of casual partners (including those with positive or unknown serostatus and with anal intercourse with casual partners. Nitrite inhalant use was not associated with non-use of condoms with casual sexual partners per se. Conclusion Contemporary use of nitrite inhalants amongst young MSM is common and a strong indicator of anal intercourse with casual sexual partners. Since use appears to increase the probability of infection following exposure to HIV, efforts to reduce the use of nitrite inhalants among MSM should be a very high priority among HIV prevention strategies.

    It is unknown whether muscle size of intrinsic hand muscles is associated with handgrip strength. To investigate the relationships between handgrip strength and flexor muscle size of the hand and forearm, muscle thickness (MT) of 86 young adults (43 men and 43 women) between the ages of 18 and 34 y was measured by ultrasound. Two MTs (forearm radius and forearm ulna MT) in the anterior forearm, two MTs (lumbrical and dorsal interosseous MT) in the anterior hand and handgrip strength were measured on the right side. Linear regression with part (also referred to as semipartial) correlation coefficients revealed that forearm ulna MT positively correlated with handgrip strength in both men (part = 0.379, p = 0.001) and women (part = 0.268, p = 0.002). Dorsal interosseous MT correlated with handgrip strength in women only (part = 0.289, p = 0.001). Our results suggest that the forearm ulna and dorsal interosseous MTs for women and forearm ulna MTs for men are factors contributing to prediction of handgrip strength in young adults.

    [Purpose] This study was designed to determine whether smoking affects endothelium function after cold therapy in young men. [Subjects] The final cohort included 27 healthy men (age, 20-21 years). Because an impact on vascular endothelium function was anticipated to be caused by smoking, the study enrolled 14 participants in a smoking group and 13 in a non-smoking group. [Methods] Vascular endothelial function was assessed by determining the reactive hyperemia index (RHI), using finger-tonometry. RHI was measured twice, at rest (baseline) and after a cold stimulus. The forearm was cooled with an ice bag for 10 min as the cold stimulus. Comparisons between the RHI at baseline and after cold treatment, and between the smoking and non-smoking groups, were performed using the paired and unpaired t-tests, respectively. [Results] There was a significant difference in baseline RHI values between the smoking and non-smoking groups, but there was no significant difference between the baseline and post-treatment RHI values in either group. [Conclusion] These results suggest that cigarette smoking damages the endothelial cells in young men with a short history of smoking. However, cold therapy did not have a significant impact on the RHI in either group.

    Keeping to a balanced diet plays a key role in maximizing the body's efficiency so that sports training becomes more effective. Previous studies have shown that an athletes' diet is often not properly balanced, and can thus negatively affect sporting performance. To assess the energy and nutrient intake in young men practicing aerobic sport and compare them with those recommended. Subjects were 25 male athletes, aged 19-25 years, practicing aerobic sports who were students at two Warsaw Universities; The Military University of Technology and University of Physical Education. The average body mass was 80.6 +/- 9.6 kg and average height was 187.0 +/- 7.6 cm, (BMI thus being 23.01 +/- 1.70 kg/m2). Dietary assessment was based on three-day dietary recalls consisting of two weekdays and one day of the weekend. The energy and macro/ micro-nutrient intake were evaluated using the Polish Software 'Energia' package and compared to recommendations and standards. Supplements were absent from the athletes' diets. The energy value of diets were too low in most instances; average %-age deficiency was 30.22 +/- 13.76%. Total protein intake, (mean 1.41 +/- 0.36 g per kg body weight) was inadequate in 40% of cases, whilst all showed appropriate intakes of animal protein. Most subjects' carbohydrate intake (84%) was deficient; median 3.28 g/kg body weight. Fibre intake, (median 17.17 g) was also insufficient in 76% cases. Total fat intake, (33.9% +/- 5.7 energy) was too high in 32% of cases. The %-age dietary energy obtained from saturated fatty acids was 12.18% +/- 2.53 and 5.72% +/- 1.43 from polyunsaturated fatty acids, where most subjects' diet (64%) was, as well, high in cholesterol. Furthermore, significant deficiencies were observed in the following: Vitamin A (44% of group below EAR), vitamin C (80% below EAR), vitamin D (92% below EAR), foliate (84% below EAR), calcium (52% below EAR) and magnesium (60% below EAR). Vitamin E intake was however higher than the AI level

  10. Health and Masculinities Shaped by Agency within Structures among Young Unemployed Men in a Northern Swedish Context.

    Full Text Available The aim of our paper was to explore expressions of life choices and life chances (aspects of agency within structures related to power and experiences of health among early unemployed adolescent young men during the transition period to adulthood. These expressions of agency within structure were interpreted in the light of Cockerham's Health Lifestyles Theory. Furthermore, social constructions of masculinities were addressed in our analysis.Repeated interviews with ten young men in a cohort of school leavers were analyzed with qualitative content analysis.Cockerham's model was useful for interpreting our findings and we found disposition to act to be a crucial theoretical tool to capture the will and intentions of participants in relation to health. We developed the model in the following ways: structure and socialization were visualized as surrounding the whole model. Analyses of what enhances or restricts power are important. In addition to practices of health lifestyles, we added experiences of health as outcome as well as emotional aspects in disposition to act. We interpret our findings as constructions of masculinities within certain structures, in relation to choices, habitus and practices.Qualitative research could contribute to develop the understanding of the agency within structure relationships. Future studies need to pay attention to experiences of health among young people at the margin of the labor market in various milieus--and to analyze these in relation to gender constructions and within the frame-work of agency within structure.

    Full Text Available To assess the prevalence of osteoporosis in young men with hypogonadotropic hypogonadism (HH and to investigate the changes of BMD and metabolic parameters, a total of 22 young male patients with HH and 20 healthy controls were enrolled in the study. BMD, biochemical, and hormonal parameters were measured in two groups. Osteoporosis was more prevalent in HH patients (45.45% than the control subjects (10.00% (P<0.001. The patients with HH had lower BMD in lumbar spine 2–4, femoral neck, and total hip (P<0.001, for all and higher fasting insulin (P=0.001, HOMA-IR (P=0.002, and SHBG (P<0.001 compared to the controls. After 6 months of pulsatile gonadorelin treatment, BMI (P=0.021 and BMD in lumbar spine 2–4, femoral neck, and total hip (P=0.002, P=0.003, and P=0.003, resp. increased dramatically and total cholesterol (P=0.034, fasting insulin (P=0.025, HOMA-IR (P=0.021, and SHBG (P=0.001 decreased significantly in HH patients. The study shows a higher prevalence of osteoporosis in young men with HH. Long-term pulsatile gonadorelin treatment indicates a positive effect on BMD and metabolic parameters of HH patients.

    This study aims to measure the associations of physical activity and one of its components, sport and exercise, with at-risk substance use in a population of young men. Baseline (2010-2012) and follow-up (2012-2013) data of 4748 young Swiss men from the Cohort Study on Substance Use Risk Factors (C-SURF) were used. Cross-sectional and prospective associations between at-risk substance use and both sport and exercise and physical activities were measured using Chi-squared tests and logistic regression models adjusting for covariates. At baseline, logistic regression indicated that sport and exercise is negatively associated with at-risk use of cigarettes and cannabis. A positive association was obtained between physical activity and at-risk alcohol use. At baseline, sport and exercise was negatively associated with at-risk use of cigarettes and cannabis at follow-up. Adjusted for sport and exercise, physical activity was positively associated with at-risk use of cigarettes and cannabis. Sport and exercise is cross-sectionally and longitudinally associated with a low prevalence of at-risk use of cigarettes and cannabis. This protective effect was not observed for physical activity broadly defined. Taking a substance use prevention perspective, the promotion of sport and exercise among young adults should be encouraged. Copyright © 2014 Elsevier Inc. All rights reserved.

    Sexual minorities experience greater mental health issues compared to heterosexuals due to minority stressors. This study focused on the impact of victimization and neuroticism on mental health in young men who have sex with men (YMSM), and the mediating role of internalized homophobia (IH). IH refers to when a sexual minority person internalizes social bias and develops a negative view of themselves, which is a likely process through which victimization and neuroticism impact mental health. Data were collected over three time points across 12 months, with 450 YMSM (mean age = 18.9) and an 80.7% retention rate. Two mediation analyses with bias-corrected bootstrapping using 1000 samples were conducted, controlling for age, race, and sexual orientation. Results revealed that victimization [F (9, 440) = 4.83, p < .001, R(2) = .09] and neuroticism [F (9, 440) = 12.23, p < .001, R(2) = .20] had a significant indirect effect on mental health via increased levels of IH. These findings show how external experiences of stigma and personality level characteristics may impact YMSM in terms of their sense of self. Furthermore, these results support addressing social conditions that marginalize YMSM in order to promote better mental health through decreasing IH.

    Young men who have sex with men (YMSM) experience minority stressors that impact their mental health, substance use, and sexual risk behaviors. Internalized homophobia (IH) and perceived stigma represent two of these minority stressors, and there has been limited research empirically validating measures of these constructs. We validated measures of IH and perceived stigma with a sample of 450 YMSM (mean age=18.9) and a sample of 370 YMSM (mean age=22.9). Results from exploratory and confirmatory factor analyses supported modifications to the IH and perceived stigma scales, ultimately revealing a three factor and one factor structure, respectively. Convergent and discriminant validity were examined utilizing correlations between IH, perceived stigma, and other variables related to minority stress (e.g., victimization). We evaluated predictive validity by examining relations with mental health, substance use, and risky sexual behaviors measured 12-months from baseline. There were mixed findings for IH, with subscales varying in their relations to mental health, drinking, and sexual risk variables. Perceived stigma was not related to mental health or substance use, but was associated with greater prevalence of STIs. Findings supported the use of these modified scales with YMSM and highlight the need for further measurement studies.

    The objective of this study was to characterize and compare individual and sexual network characteristics of Black, White, and Latino young men who have sex with men (YMSM) as potential drivers of racial disparities in HIV. Egocentric network interviews were conducted with 175 diverse YMSM who described 837 sex partners within 167 sexual-active egos. Sexual partner alter attributes were summarized by ego. Descriptives of ego demographics, sexual partner demographics, and network characteristics were calculated by race of the ego and compared. No racial differences were found in individual engagement in HIV risk behaviors or concurrent sexual partnership. Racial differences were found in partner characteristics, including female gender, non-gay sexual orientations, older age, and residence in a high HIV prevalence neighborhood. Racial differences in relationship characteristics included type of relationships (i.e., main partner) and strength of relationships. Network characteristics also showed differences, including sexual network density and assortativity by race. Most racial differences were in the direction of effects that would tend to increase HIV incidence among Black YMSM. These data suggest that racial disparities in HIV may be driven and/or maintained by a combination of racial differences in partner characteristics, assortativity by race, and increased sexual network density, rather than differences in individual's HIV risk behaviors.

    Given the popularity of social media among young men who have sex with men (YMSM), and in light of YMSM's elevated and increasing HIV rates, we tested the feasibility, acceptability and preliminary efficacy of a live chat intervention delivered on Facebook in reducing condomless anal sex and substance use within a group of high risk YMSM in a pre-post design with no control group. Participants (N = 41; 18-29 years old) completed up to eight one-hour motivational interviewing and cognitive behavioral skills-based online live chat intervention sessions, and reported on demographic, psychosocial, and behavioral characteristics at baseline and immediately post-intervention. Analyses indicated that participation in the intervention (n = 31) was associated with reductions of days of drug and alcohol use in the past month and instances of anal sex without a condom (including under the influence of substances), as well as increases in knowledge of HIV-related risks at 3-month follow-up. This pilot study argues for the potential of this social media-delivered intervention to reduce HIV risk among a most vulnerable group in the United States, in a manner that was highly acceptable to receive and feasible to execute. A future randomized controlled trial could generate an intervention blueprint for providers to support YMSM's wellbeing by reaching them regardless of their geographical location, at a low cost.

  18. Setting an Agenda to Address Intimate Partner Violence Among Young Men Who Have Sex With Men: A Conceptual Model and Review.

    Research investigating intimate partner violence (IPV) among sexual minorities is limited. The research that does exist has found that rates of IPV are similar to or higher than the rates found for heterosexual women, the most commonly studied population in this area. This limited research has resulted in a dearth of prevention/intervention programs targeted for these populations. While some may argue that existing IPV programs can be used for these populations, this review presents an argument for more targeted work with sexual minority populations, using young men who have sex with men (YMSM) as an example. Drawing on the framework of intersectionality, this article argues that the intersectionality of age, sexual identity, and gender combines to create a spectrum of unique factors that require specific attention. This framework allows for the identification of known correlates for IPV as well as factors that may be unique to YMSM or other sexual minority populations. The article presents a conceptual model that suggests new areas of research as well as a foundation for the topics and issues that should be addressed in an intervention.

    Black young men who have sex with men (BYMSM) experience higher human immunodeficiency virus (HIV) incidence than their white and Latino counterparts. The aim of our study was to understand BYMSM's preferences for mobile phone-based HIV prevention and treatment in order to inform culturally tailored interventions to reduce the spread of HIV and improve HIV treatment outcomes in this population. Qualitative focus groups (N=6) with BYMSM aged 18-29 years (N=41; 46%, 19/41 HIV-positive) were conducted to elucidate their preferences for the design and delivery of mobile phone-based HIV prevention and treatment interventions. A modified grounded theory approach to data analysis was undertaken using ATLAS.ti textual analysis software. Participants preferred holistic health interventions that did not focus exclusively on HIV prevention and treatment. Issues of privacy and confidentiality were paramount. Participants preferred functionality that enables discreet connections to culturally competent health educators and treatment providers who can address the range of health and psychosocial concerns faced by BYMSM. Mobile phone-based HIV prevention has the potential to increase engagement with HIV prevention and treatment resources among BYMSM. For these approaches to be successful, researchers must include BYMSM in the design and creation of these interventions.

    South Africa has seen a rapid increase in scholarship and programmatic interventions focusing on gender and sexuality, and more recently on boys, men and masculinities. In this paper, we argue that a deterministic discourse on men's sexuality and masculinity in general is inherent in many current understandings of adolescent male sexuality, which tend to assume that young women are vulnerable and powerless and young men are sexually powerful and inevitably also the perpetrators of sexual violence. Framed within a feminist, social constructionist the oretical perspective, the current research looked at how the masculinity and sexuality of South African young men is constructed, challenged or maintained. Focus groups were conducted with young men between the ages of 15 and 20 years from five different schools in two regions of South Africa, the Western and Eastern Cape. Data were analysed using Gilligan's listening guide method. Findings suggest that participants in this study have internalised the notion of themselves as dangerous, but were also exploring other possible ways of being male and being sexual, demonstrating more complex experiences of manhood. We argue for the importance of documenting and highlighting the precariousness, vulnerability and uncertainty of young men in scholarly and programmatic work on masculinities. PMID:25803702

    1. When nineteen "free-living" male students, who normally ate 231 (SEM 14) g white bread/d changed to wholemeal bread for a 19-week period, there was no significant change in body-weight, plasma cholesterol or plasma triglyceride levels. These values, as well as plasma concentrations of calcium, phosphate, urate and haemoglobin, remained essentially the same as those for a control group. 2. Increasing the wheat-fibre intake by eating wholemeal bread is not an effective method for reducing blood lipids levels, at least in healthy young men with a moderate bread intake.

    Background: Filaggrin is an epidermal protein that is crucial for skin barrier function. Up to 10% of Europeans and 5% of Asians carry at least one null allele in the filaggrin gene (FLG). Reduced expression of filaggrin in carriers of the null allele is associated with facilitated transfer of allergens across the epidermis. We hypothesized that these individuals may have increased transdermal uptake of endocrine disruptors, including phthalates. Objectives: We investigated urinary excretion of phthalate metabolites and testicular function in young men with and without FLG loss-of-function variants in a cross-sectional study of 861 young men from the general Danish population. Methods: All men were genotyped for FLG R501X, 2282del4, and R2447X loss-of-function variants. We measured urinary concentrations of 14 phthalate metabolites and serum levels of reproductive hormones. We also evaluated semen quality. Results: Sixty-five men (7.5%) carried at least one FLG-null allele. FLG-null carriers had significantly higher urinary concentrations of several phthalate metabolites, including a 33% higher concentration of MnBP (mono-n-butyl phthalate; 95% CI: 16, 51%). FLG-null variants were not significantly associated with reproductive hormones or semen quality parameters. Conclusion: This study provides evidence that carriers of FLG loss-of-function alleles may have higher internal exposure to phthalates, possibly due to increased transepidermal absorption. FLG loss-of-function variants may indicate susceptible populations for which special attention to transepidermal absorption of chemicals and medication may be warranted.

    During Rwanda's genocide period in 1994, about 800,000 people were killed. People were murdered, raped and seriously injured. This retrospective study investigated prevalence and frequency of traumatic episodes and associated psychosocial effects in young adults in Rwanda over the lifetime, during the genocide period and in the past three years. This is a cross-sectional population-based study conducted among men and women, aged 20 to 35 years, residing in the Southern province of Rwanda. The study population, randomly selected in a multi stage procedure, included 477 females and 440 males. Data collection was performed through individual interviewing with a structured questionnaire during the period December 2011- January 2012. The Harvard Trauma Questionnaire was used to assess traumatic episodes. All data was sex-disaggregated. Differences between groups were measured by chi square and Fischer's exact test. Associations with socio-demographic and psychosocial factors were estimated by use of odds ratios with 95% confidence intervals in bi- and multivariate analyses. The participants in this study were 3 to 18 years of age in 1994, the year of the genocide. Our sample size was 917 participants, 440 men and 477 women. Women were to a higher extent exposed to traumatic episodes than men during their lifetime, 83.6% (n = 399) and 73.4% (n = 323), respectively. During the genocide period, 37.5% of the men/boys and 35.4% of the women/girls reported such episodes while in the past three years (2009-2011) 25.0% of the men and 23.1% of the women did. Women were more exposed to episodes related to physical and sexual violence, while men were exposed to imprisonment, kidnapping and mass killings. Victims of such violence during the genocide period were 17 years later less educated although married (men OR 1.47; 0.98-2.19; women OR 1.54; 1.03-2.30), without children (men OR 1.59; 1.08-2.36; women OR 1.86; 1.11-3.08) and living under extremely poor circumstances.

    Young adults, particularly young gay men (YGM), are vulnerable to human immunodeficiency virus (HIV). Yet, little is known about how YGM discuss sexual health issues with their friends ('gay boy talk'). We conducted semi-structured interviews with YGM and their best friends (11 YGM/YGM dyads and 13 YGM/heterosexual female dyads). In this paper, we examine risk assessment assumptions conveyed within YGM's communication about sexual health with their friends and how, if at all, the sexual scripts guiding these assumptions may differ between YGM and young women. Findings demonstrated that, while these young adults clearly intended to support their friends and promote safer sex, they also conveyed assumptions about HIV risk assessment, especially regarding sexual partner selection, that may actually increase their friends' risk for HIV infection. Since inaccurate HIV risk assessment assumptions were transmitted via sexual health communication between peers, it is suggested that such assumptions may need to be addressed in HIV prevention programs working with YGM and their friends. Further, gender differences were identified within the sexual scripts shared between YGM and their friends, suggesting that such interventions should be tailored to the specific needs of different friendship networks.

    We examined the association of body composition and body mass index (BMI) with submaximal systolic blood pressure (SSBP) among young adult men. The analysis included 211 men with BMI between 20 and 35 kg/m(2). Total lean mass and fat mass were measured using dual x-ray absorptiometry and lean mass percentage was calculated from the total lean mass. Fat mass index (FMI) and BMI were calculated using height and weight (total fat mass and total weight, respectively) measurements. SSBP was measured at each stage of a graded exercise test. Quintiles of lean mass percentage, FMI, and BMI were created with quintile 1 the lowest and quintile 5 the highest lean mass percentage, FMI, and BMI. Compared with men in lean mass percentage quintile 1, those in quintiles 2, 3, and 4 had significantly lower SSBP, whereas there was no significant difference in SSBP between quintile 1 and 5 at 6, 8, and 10 minutes. Compared with men in FMI quintile 5, those in quintiles 2, 3, and 4 had significantly lower SSBP, whereas there was no significant difference in SSBP between quintile 1 and 5. SSBP among men in lean mass percentage quintile 5 and FMI quintile 1 were still less than lean mass percentage quintile 1 and FMI quintile 5, respectively. There were no significant differences in SSBP across BMI quintiles 1 to 4 but a significantly higher SSBP in quintile 5 compared with quintiles 1 to 4. In conclusion, there was a J-curve pattern between SSBP and components of body composition, whereas, a linear relation between SSBP and BMI.

    Depression is common among young people. Gender differences in diagnosing depression appear during adolescence. The study aim was to explore the impact of gender on depression in young Swedish men and women. Grounded theory was used to analyze interviews with 23 young people aged 17 to 25 years who had been diagnosed with depression. Their narratives were marked by a striving to be normal and disclosed strong gender stereotypes, constructed in interaction with parents, friends, and the media. Gender norms were upheld by feelings of shame, and restricted the acting space of our informants. However, we also found transgressions of these gender norms. Primary health care workers could encourage young men to open up emotionally and communicate their personal distress, and young women to be daring and assertive of their own strengths, so that both genders might gain access to the positive coping strategies practiced respectively by each.

    [Purpose] The aim of the present study was to investigate the effects of aerobic exercise training on the levels of peripheral brain-derived neurotrophic factor and eotaxin-1 in obese young men. [Subjects and Methods] The subjects included sixteen obese young men with a body mass index greater than 25 kg/m(2). They were randomly divided between control and exercise groups (n = 8 in each group). The exercise group performed treadmill exercise for 40 min, 3 times a week for 8 weeks at the intensity of 70% heart rate reserve. Blood collection was performed to examine the levels of serum glucose, plasma malonaldehyde, serum brain-derived neurotrophic factor, and plasma eotaxin-1 before and after the intervention (aerobic exercise training). [Results] Following the intervention, serum BDNF levels were significantly higher, while serum glucose, plasma MDA, and plasma eotaxin-1 levels were significantly lower than those prior to the intervention in the exercise group. [Conclusion] Aerobic exercise training can induce neurogenesis in obese individuals by increasing the levels of brain-derived neurotrophic factor and reducing the levels of eotaxin-1. Alleviation of oxidative stress is possibly responsible for such changes.

    To investigate the relationship of concussion(s) suffered through childhood and adolescence with completed level of school education and cognitive ability in young adulthood. Educational level and scores on a test of cognitive ability were obtained for a cohort of 130,298 young men processed by the Danish draft board. Of these, 6146 had, at some age from birth onwards, been briefly admitted to hospital with a main discharge diagnosis of concussion. A further 402 had two such concussions and 48 had three or more. Educational level and cognitive ability test scores were negatively associated with the number of concussions and the age at concussion(s). Most markedly, compared to the 123,684 non-concussed men, those with two or more concussions had lower educational levels (OR = 0.48; 95% CI = 0.26-0.89), as also did those sustaining one concussion between the age of 13 up to the time of testing (OR = 0.47: 0.42-0.52). Since concussions do not generally have long-term effects, the results suggest that lower educational level is primarily a risk factor for sustaining a concussion at all ages, but in particular in adolescence more than in childhood and in the case of multiple concussions. It should, however, be recognized that, in some proportion of cases, the educational deficits have probably arisen as a consequence of the persistent symptoms of a lengthy post-concussional syndrome.

    The aim of the present study was to evaluate the apparent disagreement regarding the effect of a typical cycling progressive exercise, commonly used to assess VO2max, on the kinetics of ex vivo copper induced peroxidation of serum lipids. Thirty-two (32) healthy young men, aged 24-30 years, who do not smoke and do not take any food supplements, participated in the study. Blood was withdrawn from each participant at three time points (before the exercise and 5 minutes and one hour after exercise). Copper induced peroxidation of sera made of the blood samples was monitored by spectrophotometry. For comparison, we also assayed TBARS concentration and the activity of oxidation-related enzymes. The physical exercise resulted in a slight and reversible increase of TBARS and slight changes in the activities of the studied antioxidant enzymes and the lag preceding peroxidation did not change substantially. Most altered parameters returned to baseline level one hour after exercise. Notably, the exercise-induced changes in OS did not correlate with the physical fitness of the subjects, as evaluated in this study (VO2max = 30-60 mL/min/kg). We conclude that in healthy young fit men a short exhaustive exercise alters only slightly the OS, independent of the actual physical fitness.

    This study investigates the relationships between physical activity (PA), sports participation and sensation seeking or aggression and injury risk in young men. A representative cohort study was conducted with 4686 conscripts for the Swiss army. Risk factors assessed at baseline were PA, the frequency of sports participation, sensation seeking, and aggression. The number of injuries during the past 12 months was reported 16 months after baseline. Exposure to moderate-tovigorous physical activity (MVPA) was estimated based on baseline PA. Among conscripts, 48.5% reported at least 1 injury for the past 12 months. After accounting for exposure to MVPA, the most inactive individuals (reference group) had the highest injury risk and those with high levels of PA and weekly sports participation the lowest (Poisson regression analysis: incidence rate ratio = 0.14 [0.12-0.16]). Independent of activity level, sensation seeking increased cumulative injury incidence significantly (Logistic regression analysis [injured vs. not injured]: odds ratio = 1.29 [1.02-1.63]) and incidence rates marginally. Aggression was marginally associated only with cumulative injury incidence and only in those participating in daily sports. When accounting for exposure to PA, being inactive is a strong injury risk factor in young men, whereas the roles of the personality variables are less clear.

    This paper analyzes relationships among self-esteem, educational attainment, and occupational status. Data from a nationwide longitudinal study of more than 1600 young men show a substantial increase in self-esteem between 19TT (when respondents were beginning tenth grade) and 1974. Reliability and construct validity data for the self-esteem measure are reported. As expected, both educational attainment and occupational status are correlated with self-esteem. Contrary to expectations, educational attainment as of 1974 is more strongly correlated with tenth grade self-esteem than with 1974 self-esteem. A path analysis led to these conclusions: (a) Self-esteem during high school has little or no direct causal impact on later educational and occupational attainment; self-esteem and attainment are correlated primarily because of shared prior causes including family background, ability, and scholastic performance. (b) Occupational status has a direct positive impact on self-esteem. (c) Post high school educational attainment has no direct impact on self-esteem and only a trivial indirect impact via occupational status. Additional findings indicate that factors associated with educational success become less central to the self-evaluations of young men during late high school and the years thereafter.

    Full Text Available The present study examined the effects of progressive exercise (pyramidal short-term program on plasma fibrinogen, lipid profile and blood viscosity in untrained young men. Changes and imbalances in homeostasis lead to cause of heart attacks. There is conflicting information about the effect of exercise on these factors. 19 young healthy untrained men were randomly assigned to the exercise group (n = 10 and controls (n = 9 groups. Exercise training group with increasing severity of heart maximum 25 to 100 percent began to run the practice (pyramid in 42-minute sessions, 3 times a week, for 4 weeks. There was no significant difference between the parameters of body composition, control, and training groups. Levels of total cholesterol and low density lipoprotein density and viscosity of the blood significantly decreased in the training group compared with the control group (p value, respectively is 0.001, 0.001 and 0.035. The changes in the concentration of fibrinogen, high-density lipoprotein and triglycerides in both groups are not significant in both groups (p value, respectively is 0.645, 0.993 and 0.421. The present results show that it is possible that progressive training (pyramidal short-term program changed the levels of cardiovascular risk factors by reducing blood viscosity.

    We examined the role of financial strain, parent-to-parent violence, parent-to-child violence, emotional distress, and alcohol use in intimate partner violence perpetrated by young adult women against men in Ukraine. The moderating role of acceptability of intimate partner violence and violence-related laws and regulations was also examined. Four hundred and six full-time female university students from four universities in Ukraine participated in the study. We found that emotional distress, parent-to-parent, and parent-to-child violence mediated the link between financial strain and intimate partner violence perpetrated by women on men. However, we found limited support for the moderating role of acceptability of intimate partner violence and violence-related laws and regulations in the relationship between individual and familial factors on intimate partner violence. The findings from this investigation suggest that there is a distinct need for supporting families and individuals in dealing with issues of intimate partner violence directed by women against men in Ukraine.

    Some evidence suggests that youth who use marijuana heavily during adolescence may be particularly prone to health problems in later adulthood (e.g., respiratory illnesses, psychotic symptoms). However, relatively few longitudinal studies have prospectively examined the long-term physical and mental health consequences associated with chronic adolescent marijuana use. The present study used data from a longitudinal sample of Black and White young men to determine whether different developmental patterns of marijuana use, assessed annually from early adolescence to the mid-20s, were associated with adverse physical (e.g., asthma, high blood pressure) and mental (e.g., psychosis, anxiety disorders) health outcomes in the mid-30s. Analyses also examined whether chronic marijuana use was more strongly associated with later health problems in Black men relative to White men. Findings from latent class growth curve analysis identified 4 distinct subgroups of marijuana users: early onset chronic users, late increasing users, adolescence-limited users, and low/nonusers. Results indicated that the 4 marijuana use trajectory groups were not significantly different in terms of their physical and mental health problems assessed in the mid-30s. The associations between marijuana group membership and later health problems did not vary significantly by race. Findings are discussed in the context of a larger body of work investigating the potential long-term health consequences of early onset chronic marijuana use, as well as the complications inherent in studying the possible link between marijuana use and health effects.

    The association between low birthweight (LBW) and risk of developing type 2 diabetes may involve epigenetic mechanisms, with skeletal muscle being a prime target tissue. Differential DNA methylation patterns have been observed in single genes in muscle tissue from type 2 diabetic and LBW individuals, and we recently showed multiple DNA methylation changes during short-term high-fat overfeeding in muscle of healthy people. In a randomised crossover study, we analysed genome-wide DNA promoter methylation in skeletal muscle of 17 young LBW men and 23 matched normal birthweight (NBW) men after a control and a 5 day high-fat overfeeding diet. DNA methylation was measured using Illumina's Infinium BeadArray covering 27,578 CpG sites representing 14,475 different genes. After correction for multiple comparisons, DNA methylation levels were found to be similar in the LBW and NBW groups during the control diet. Whereas widespread DNA methylation changes were observed in the NBW group in response to high-fat overfeeding, only a few methylation changes were seen in the LBW group (χ(2), p muscle from LBW vs NBW men, potentially contributing to understanding the link between LBW and increased risk of type 2 diabetes.

    This analysis aimed to determine whether the relationship between a history of arrest and unprotected anal sex (UAS) is the same for Black/Latino gay, bisexual, and other young men who have sex with men (YMSM) as compared to White/Asian/Pacific Islander (API) YMSM in New York City (NYC). Baseline audio-computer-assisted self-interview (ACASI) and interviewer-administered survey data from a sample of 576 YMSM aged 18-19 years old who self-reported being HIV-negative were analyzed. Data included history of arrest and incarceration as well as UAS in the past 30 days. Race/ethnicity was an effect modifier of the association between arrest and UAS among YMSM: White/API YMSM with a lifetime arrest history were more than three times as likely to report UAS, and Black/Latino YMSM with a lifetime history of arrest were approximately 70 % less likely to report UAS as compared with White/API YMSM with no reported arrest history. Race/ethnicity may modify the relationship between arrest and sexual risk behavior because the etiology of arrest differs by race, as partially evidenced by racial/ethnic disparities in police stop, arrest, and incarceration rates in NYC. Arrest could not only be an indicator of risky behavior for White/API YMSM but also an indicator of discrimination for Black/Latino YMSM. Further research is needed to assess whether the differential associations observed here vis-à-vis race/ethnicity are robust across different populations and different health outcomes.

    Phylogenetic analysis determines similarities among HIV genetic sequences from persons infected with HIV, identifying clusters of transmission. We determined characteristics associated with both membership in an HIV transmission cluster and the number of clustered sequences among a cohort of young black men who have sex with men (YBMSM) in Chicago. Pairwise genetic distances of HIV-1 pol sequences were collected during 2013-2016. Potential transmission ties were identified among HIV-infected persons whose sequences were ≤1.5% genetically distant. Putative transmission pairs were defined as ≥1 tie to another sequence. We then determined demographic and risk attributes associated with both membership in an HIV transmission cluster and the number of ties to the sequences from other persons in the cluster. Of 86 available sequences, 31 (36.0%) were tied to ≥1 other sequence. Through multivariable analyses, we determined that those who reported symptoms of depression and those who had a higher number of confidants in their network had significantly decreased odds of membership in transmission clusters. We found that those who had unstable housing and who reported heavy marijuana use had significantly more ties to other individuals within transmission clusters, whereas those identifying as bisexual, those participating in group sex, and those with higher numbers of sexual partners had significantly fewer ties. This study demonstrates the potential for combining phylogenetic and individual and network attributes to target HIV control efforts to persons with potentially higher transmission risk, as well as suggesting some unappreciated specific predictors of transmission risk among YBMSM in Chicago for future study.

    Background In the United States, the human immunodeficiency virus (HIV) disproportionately affects young men who have sex with men (YMSM). For HIV-positive individuals, adherence to antiretroviral therapy (ART) is critical for achieving optimal health outcomes and reducing secondary transmission of HIV. However, YMSM often struggle with ART adherence. Novel mobile phone apps that incorporate game-based mechanics and social networking elements represent a promising intervention approach for improving ART adherence among YMSM. Objective This study used a multiphase, iterative development process to create an ART adherence app for YMSM. Methods The three-phase development process included: (1) theory-based concept development jointly by public health researchers and the technology team, (2) assessment of the target population’s ART adherence needs and app preferences and development and testing of a clickable app prototype, and (3) development and usability testing of the final app prototype. Results The initial theory-based app concept developed in Phase One included medication reminders, daily ART adherence tracking and visualization, ART educational modules, limited virtual interactions with other app users, and gamification elements. In Phase Two, adherence needs, including those related to information, motivation, and behavioral skills, were identified. Participants expressed preferences for an ART adherence app that was informational, interactive, social, and customizable. Based on the findings from Phase Two, additional gaming features were added in Phase Three, including an interactive battle, superhero app theme, and app storyline. Other features were modified to increase interactivity and customization options and integrate the game theme. During usability testing of the final prototype, participants were able to understand and navigate the app successfully and rated the app favorably. Conclusions An iterative development process was critical for the

    The endogenous social support systems of young Black men who have sex with men (YBMSM), like surrogate families and social networks, are considered crucial assets for HIV prevention in this population. Yet, the extent to which these social systems foster sexual health protections or risks remains unclear. We examine the networked patterns of membership in ballroom houses and independent gay families, both Black gay subcultures in the United States, and how these memberships are related to HIV protective and risk traits of members. Drawing from a population-based sample of 618 YBMSM living in Chicago between June 2013 and July 2014, we observe a suite of protective and risk traits and perform bivariate analyses to assess each of their associations with being a member of a house or family. We then present an analysis of the homophilous and heterophilous mixing on these traits that structures the patterns of house and family affiliations among members. The bivariate analyses show that members of the house and family communities were more likely than non-members to report protective traits like being aware of PrEP, having health coverage, having a primary care doctor, and discouraging sex drug use among peers. However, members were also more likely to engage in the use of sex drugs. With respect to how these traits inform specific house/family affiliations, results show that members who had a recent HIV test, who were PrEP aware, or who engaged in exchange sex were more likely to belong to the same house or family, while HIV positive individuals were less likely to cluster within houses or families. These findings provide insights regarding the strengths and vulnerabilities of the house and gay family communities that can inform more culturally specific interventions that build on the existing human and social capital in this milieu.

    The rate of HIV infections among young black men who have sex with men (YBMSM) continues to rise at an alarming pace. YBMSM are particularly vulnerable to social isolation and a lack of social support due to experiences with racism and homophobia, which may have implications for sexual risk behaviors. The purpose of this study was to explore perceptions of social isolation and sense of community among YBMSM, the need for and receptivity to social networking features designed to reduce social isolation and build community within an Internet- and mobile phone-based primary and secondary HIV prevention intervention for YBMSM and to identify strategies to develop these features. Focus groups were conducted with 22 YBMSM aged 20-30 years at three sites in North Carolina. Data from the focus groups were thematically analyzed using NVivo. Feelings of social isolation and lack of a sense of community were strongly endorsed by participants with homophobia, lack of opportunities for social engagement, and a focus on sex rather than friendship in interpersonal relationships with other YBMSM cited as contributing factors. Participants were receptive to a social networking intervention designed to reduce social isolation and build community. Recommendations offered by participants to increase acceptability and usability of such features included: availability of information about healthy relationships, the ability to connect with other YBMSM and health care providers, and ensuring the site had ongoing facilitation by the study team as well as monitoring for inappropriate content. The development of a social networking feature of an HIV prevention intervention may present an opportunity to reduce social isolation, build community, and reduce risky sexual behaviors among YBMSM. The findings from this study are being used to inform the development of a social networking feature for an existing Internet- and mobile phone-based primary and secondary HIV prevention intervention for

    Cardiovascular diseases (CVD) risk factors are increasing at an unprecedented rate in developing countries. However, fewer studies have evaluated the role of physical activity in preventing CVD in these countries. We assessed level physical activity and its relationship with CVD risk factors among young and middle aged men in a fast growing city of Mwanza in Tanzania. Physical activity was assessed among 97 healthy men aged 20-50 years using Sub-Saharan Africa Activity Questionnaire. An updated compendium of physical activity was used to code the metabolic equivalent. Energy expenditure was calculated using Harris Benedict equation. Anthropometric measurements, blood pressure, fasting blood glucose and serum lipids were also measured. The mean energy expenditure in this population was 6,466 ± 252 kcal/week. More than half (53.6%) of the participants had energy expenditure of ≥ 4,000 kcal/week. Only three (3.1%) had energy expenditure below the recommended 1,000 kcal/week. Except for hypertension, prevalence of CVD risk factors was low in this population; hypertension 23.7%, low HDL-cholesterol 10.3%, high LDL-cholesterol 9.3% and obesity 4.1%. Physical activity energy expenditure had an inversely relationship with waist to hip ratio, systolic blood pressure, heart rate, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides and fasting blood glucose. Physical activity energy expenditure was high in this population and was inversely correlated with CVD risk factors. Physical activity may play an important role in the prevention of CVD in this urban population of young and middle aged men.

    Over the past decade, linear and nonlinear surface electromyography (EMG) variables highlighting different components of fatigue have been developed. In this study, we tested fractal dimension (FD) and conduction velocity (CV) rate of changes as descriptors, respectively, of motor unit synchronization and peripheral manifestations of fatigue. Sixteen elderly (69  ±  4 years) and seventeen young (23  ±  2 years) physically active men (almost 3-5 h of physical activity per week) executed one knee extensor contraction at 70% of a maximal voluntary contraction for 30 s. Muscle fiber CV and FD were calculated from the multichannel surface EMG signal recorded from the vastus lateralis and medialis muscles. The main findings were that the two groups showed a similar rate of change of CV, whereas FD rate of change was higher in the young than in the elderly group. The trends were the same for both muscles. CV findings highlighted a non-different extent of peripheral manifestations of fatigue between groups. Nevertheless, FD rate of change was found to be steeper in the elderly than in the young, suggesting a greater increase in motor unit synchronization with ageing. These findings suggest that FD analysis could be used as a complementary variable providing further information on central mechanisms with respect to CV in fatiguing contractions.

    Full Text Available Abstract Background Notions of ideal manhood in South Africa are potentially prescriptive of male sexuality thus accounting for the behaviors which may lead to men being at greater HIV risk. We tested the hypothesis that gender and relationship constructs are associated with condom use among young men living in rural South Africa. Methods 1219 men aged 15–26 years completed a cross-sectional baseline survey from an IsiXhosa questionnaire asking about sexual behaviour and relationships. Univariate and bivariate analyses described condom use patterns and explanatory variables, and multinomial regression modeling assessed the factors associated with inconsistent versus consistent and non-condom use. Results 47.7% of men never used condoms, when 36.9% were inconsistent and 15.4% were consistent with any partner in the past year. Condom use patterns differed in association with gender relations attitudes: never users were significantly more conservative than inconsistent or consistent users. Three gender positions emerged indicating that inconsistent users were most physically/sexually violent and sexually risky; never users had more conservative gender attitudes but were less violent and sexually risky; and consistent users were less conservative, less violent and sexually risky with notably fewer sexual partners than inconsistent users. Conclusions The confluence of conservative gender attitudes, perpetration of violence against women and sexual risk taking distinguished inconsistent condom users as the most risky compared to never condom users, and rendered inconsistent use one of the basic negative attributes of dominant masculinities in the Eastern Cape, South Africa. This finding is important for the design of HIV prevention and gender equity interventions and emphasizes the need for a wider roll-out of interventions that promote progressive and healthy masculine practices in the country.

    Full Text Available OBJECTIVE: To assess changes in the prevalence of HIV and other sexually transmitted infections, as well as in different proximal and distal factors related to HIV infection, in the general population of Cotonou between 1998 and 2008, while an intensive preventive intervention targeting the sex work milieu was ongoing. METHODS: A two-stage cluster sampling procedure was used to select the participants in each study. Subjects aged 15-49 who agreed to participate were interviewed and tested for HIV, syphilis, HSV-2, gonorrhoea and chlamydia. We used the Roa-Scott Chi-square test (proportions and the Student's t test (means for bivariate comparisons, and adjusted logistic regression models taking into account the cluster effect for multivariate analyses. RESULTS: HIV prevalence decreased significantly in men (3.4% in 1998 versus 2.0% in 2008, p = 0.048, especially in those aged 15-29 (3.0% to 0.5%, p = 0.002. Among men, the prevalence of gonorrhoea decreased significantly (1.1% to 0.3%, p = 0.046 while HSV-2 prevalence increased from 12.0% to 18.1% (p = 0.0003. The proportion of men who reported condom use at least once (29.3% to 61.0%, p<0.0001 and of those having attained a secondary educational level or more (17.1% to 61.3%, p<0.0001 also increased significantly. There was an overall decrease in the prevalence of syphilis (1.5% to 0.6%, p = 0.0003. CONCLUSION: This is the first population-based study reporting a significant decline in HIV prevalence among young men in an African setting where overall prevalence has never reached 5%. The decline occurred while preventive interventions targeting the sex work milieu were ongoing and the educational level was increasing.

    In the USA, young Black gay men are disproportionately impacted by HIV. In this qualitative study consisting of in-depth interviews with 31 young Black gay men and 9 service providers, where we used thematic analysis to guide our interpretations, we found that HIV-related stigma and homophobia, within the larger societal context of racism, were related to sexual risk behaviour, reluctance to obtain HIV testing or care, lower adherence to treatment medication, and disclosure of a positive HIV status to sexual partners. Participants experienced homophobia and HIV-related stigma from churches and families within the Black community, and from friends within the Black gay community, that otherwise provide support in the face of racism. Vulnerability to HIV was related to strategies that young Black gay men enacted to avoid being stigmatised or as a way of coping with their alienation and rejection. PMID:24784224

    Prior research has documented various ways in which adult attachment styles are characteristic of differential behavioral and cognitive patterns within romantic relationships and sexuality. However, few studies have examined the direct influence of anxious or avoidant attachment orientation on sexual function. The aim of the present study was to assess the impact of insecure attachment on sexual function. Undergraduate students completed questionnaires measuring attachment style and sexual functioning. Among women, attachment avoidance tended to be associated with impairments in all aspects of sexual function, whereas anxious attachment tended to be associated with declines in arousal, satisfaction, and ability to achieve orgasm. A different trend was seen in men: Anxious attachment tended to be associated with multiple facets of sexual dysfunction, while avoidant attachment did not correlate with any sexual function deficits and was associated with superior physiological competence. These results suggest that both anxious and avoidant attachment styles are important yet differential predictors of sexual function in men and women.

    Traditional forms of masculinity strongly influence men's and women's wellbeing. This study has two aims: (i) to explore notions of various forms of masculinities in young Nicaraguan men participating in programs addressing sexual health, reproductive health, and/or gender equality and (ii) to find out how these young men perceive their involvement in actions aimed at reducing violence against women (VAW). A qualitative grounded theory study. Data were collected through six focus groups and two in-depth interviews with altogether 62 young men. Our analysis showed that the informants experienced a process of change, labeled 'Expanding your mind', in which we identified four interrelated subcategories: The apprentice, The responsible/respectful man, The proactive peer educator, and 'The feminist man'. The process showed how an increased awareness of gender inequities facilitated the emergence of values (respect and responsibility) and behavior (thoughtful action) that contributed to increase the informant's critical thinking and agency at individual, social, and political levels. The process was influenced by individual and external factors. Multiple progressive masculinities can emerge from programs challenging patriarchy in this Latin American setting. The masculinities identified in this study show a range of attitudes and behaviors; however, all lean toward more equitable gender relations. The results suggest that learning about sexual and reproductive health does not directly imply developing more gender-equitable attitudes and behaviors or a greater willingness to prevent VAW. It is paramount that interventions to challenge machismo in this setting continue and are expanded to reach more young men.

    Sexual risk behaviors of young gay and bisexual men must be understood within the context of other health concerns (e.g., anxiety, substance abuse), population-specific factors (i.e., the coming-out process and gay-related stress), childhood sexual abuse, and other theoretical factors (e.g., safer sex intentions). The current report proposes and longitudinally examines a model of risk factors for subsequent sexual risk behaviors among young gay and bisexual men in New York City. As hypothesiz...

    Despite the prevalence of testicular cancer among men 15-39 years of age, little has been done to increase awareness of this disease or educate males about its prevention. To fill this gap, the Standard Model of Health Communication was incorporated to design and implement a comprehensive testicular cancer campaign among male college students. To test the effectiveness of these messages, college students (N = 220) completed measures before and after the campaign. In addition, the authors obtained a control group of male college students (N = 52) who were not exposed to the messages. Survey items assessed awareness of testicular cancer and behaviors related to testicular cancer. Participants' knowledge of testicular cancer and likelihood of conducting a testicular self-exam increased significantly after being exposed to the campaign information. Men who were exposed to testicular cancer messages were more knowledgeable about testicular cancer and were more likely to conduct testicular self-examinations than were men in the control group.

    We examined the association between HIV/AIDS risk behaviors and romantic feelings among single, young gay and bisexual men (YGBM). Romantic feelings may have positive (romantic ideation) and negative (romantic obsession) connotations. Consequently, we hypothesized that YGBM would report greater risks if they reported having obsessive thoughts about their relationship desires; conversely, we hypothesized that YGBM who envision a romantic relationship would report fewer unprotected partners. Using cross-sectional data from a study examining YGBM's online dating experiences (N = 376; ages 18-24), we found a positive association between romantic obsession and number of partners for unprotected receptive (URAI) and insertive (UIAI) anal intercourse. Conversely, we found a negative association between romantic ideation and number of partners for URAI and UIAI. Is love risky or protective? Our results indicate support for both perspectives. We discuss the implications of our findings, highlighting the importance of addressing romantic pursuits into existing HIV prevention interventions for YGBM.

    Full Text Available There has been an increased interest in the role of vitamin D in depression; however, there have been few studies conducted in younger population groups. Our aim was to investigate the association between vitamin D status and depressive symptoms in a non-clinical young adult sample living in Dunedin, New Zealand. A cross-sectional sample of 615 young adults completed a questionnaire including demographics and the Centre for Epidemiological Studies Depression Scale (CES-D. Height, weight and a blood sample for 25-hydroxyvitamin D [25(OHD] was obtained. Serum 25(OHD was used to predict depression scores, adjusting for potential confounders including time spent outdoors for 13 consecutive days, BMI, age, sex and ethnicity. Prevalence of low vitamin D was high even in this age group, and serum 25(OHD was negatively associated with depression symptoms before and after adjustment. When investigating the relationship between the presence versus absence of depressive symptoms and quartiles of 25(OHD, participants in the lowest quartile were more likely to report depressive symptoms compared with those in the highest quartile. Although our findings suggest that vitamin D is a predictor of depression symptomatology, even when controlling for time spent outdoors, a randomised controlled trial in this young adult target group is needed to confirm the association.

    The few previous studies examining the influence of the neighborhood context on health and health behavior among young gay, bisexual, and other men who have sex with men (YMSM) have predominantly focused on residential neighborhoods. No studies have examined multiple neighborhood contexts among YMSM or the relationships between sociodemographic characteristics, psychosocial factors, social support network characteristics, health behaviors, and neighborhood concordance. In this study, we assessed spatial polygamy by determining the amount of concordance between residential, social, and sex neighborhoods (defined as boroughs) in addition to examining individual-level characteristics that may be associated with neighborhood concordance. These data come from the baseline assessment of Project 18, a cohort of racially and ethnically diverse YMSM residing in the New York City metropolitan area. Participants (N = 598) provided information on their residential, social, and sex boroughs as well as information on their sociodemographic characteristics, psychosocial factors, social support network characteristics, and health behaviors (e.g., substance use and condomless sex). Descriptive analyses were conducted to examine the distribution of boroughs reported across all three contexts, i.e., residential, social, and sex boroughs. Next, concordance between: (1) residential and social boroughs; (2) residential and sex boroughs; (3) social and sex boroughs; and (4) residential, social, and sex boroughs was assessed. Finally, bivariable analyses were conducted to examine the relationships between sociodemographic characteristics, psychosocial factors, social support network characteristics, and health behaviors in relation to borough concordance. Approximately two-thirds of participants reported concordance between residential/socializing, residential/sex, and sex/socializing boroughs, whereas 25% reported concordance between all three residential/socializing/sex boroughs

    Young men who have sex with men (YMSM) continue to experience higher rates of HIV infection than other populations. Recently, there have been recommendations to consider HIV prevention at the dyadic or couple level. Using a dyadic approach to HIV prevention would also address an unaddressed concern related to intimate partner violence (IPV) among YMSM. Although research on IPV among YMSM is still in its infancy, great strides have been made in the past 10 years to describe the prevalence and related correlates of IPV within older adult same-sex relationships. These studies have found rates of IPV among MSM to be similar to rates among heterosexual women, and to be on the rise. The present study is designed to provide insight into how power is conceptualized within YMSM relationships and the role it may play in relationship challenges. This study draws from qualitative data collected from 11 focus groups with 86 YMSM and 26 individual semi-structured interviews to understand relationship challenges and the experiences of YMSM involved in partner violence. YMSM described relationship power as stemming from numerous sources including sexual positioning, gender roles, education, income, prior relationship experiences, and internalized homophobia. The findings have a number of implications for service providers and program design. Interventionists and other researchers need to consider power dynamics and other contextual elements of IPV before effective interventions can be developed for YMSM and other sexual minority populations.

    Few studies have examined the relationship between young gay and bisexual men (YGBM) and their fathers. Based on a phenomenological framework, this study investigated the role of fathers in YGBM's coming-out experience, focusing on how fathers responded to disclosure of same-sex attraction, how fathers' responses compared with sons' expectations, and what sons perceived as having influenced their fathers' responses. Semistructured in-depth interviews with 30 gay and bisexual men aged 18 to 24 years were conducted as part of a larger study; topics explored in the interview included experiences coming out to family and others. Nineteen participants' narratives included discussion about their fathers and were included in the current analyses. The YGBM who were interviewed perceived a complex range of responses upon coming out to their fathers, ranging from enthusiastic acceptance to physical violence. Participants spoke of fathers who were accepting in different manners and who often held contradictory attitudes about same-sex attraction. Fathers' responses commonly differed from sons' expectations, which were informed by homophobic talk and gendered expectations. Sons spoke about what informed their expectations as well as what they perceived as influencing their fathers' responses, including gender norms, beliefs regarding the cause of same-sex attraction, religious and sociopolitical views, and concerns about HIV/AIDS. Particularly striking was the pervasive influence of hegemonic masculinity throughout the YGBM's stories. The implications of these findings for future research and intervention development are discussed, as well as study strengths and limitations. © The Author(s) 2014.

    Muscle hypertrophy following resistance training (RT) involves activation of myofibrillar protein synthesis (MPS) to expand the myofibrillar protein pool. The degree of hypertrophy following RT is, however, highly variable and thus we sought to determine the relationship between the acute activation of MPS and RT-induced hypertrophy. We measured MPS and signalling protein activation after the first session of resistance exercise (RE) in untrained men (n = 23) and then examined the relation between MPS with magnetic resonance image determined hypertrophy. To measure MPS, young men (24±1 yr; body mass index  = 26.4±0.9 kg•m²) underwent a primed constant infusion of L-[ring-¹³C₆] phenylalanine to measure MPS at rest, and acutely following their first bout of RE prior to 16 wk of RT. Rates of MPS were increased 235±38% (Pmuscle volume and acute rates of MPS measured over 1-3 h (r = 0.02), 3-6 h (r = 0.16) or the aggregate 1-6 h post-exercise period (r = 0.10). Hypertrophy after chronic RT was correlated (r = 0.42, P = 0.05) with phosphorylation of 4E-BP1(Thr37/46) at 1 hour post RE. We conclude that acute measures of MPS following an initial exposure to RE in novices are not correlated with muscle hypertrophy following chronic RT.

    Probiotic yogurt and milk supplemented with probiotics have been investigated for their role in 'low-grade' inflammation but evidence for their efficacy is inconclusive. This study explores the impact of probiotic yogurt on metabolic and inflammatory biomarkers, with a parallel study of gut microbiota dynamics. The randomised cross-over study was conducted in fourteen healthy, young men to test probiotic yogurt compared with milk acidified with 2 % d-(+)-glucono-δ-lactone during a 2-week intervention (400 g/d). Fasting assessments, a high-fat meal test (HFM) and microbiota analyses were used to assess the intervention effects. Baseline assessments for the HFM were carried out after a run-in during which normal milk was provided. No significant differences in the inflammatory response to the HFM were observed after probiotic yogurt compared with acidified milk intake; however, both products were associated with significant reductions in the inflammatory response to the HFM compared with the baseline tests (assessed by IL6, TNFα and chemokine ligand 5) (Pmicrobiota taxa, including decreased abundance of Bilophila wadsworthia after acidified milk (log 2-fold-change (FC)=-1·5, P adj=0·05) and probiotic yogurt intake (FC=-1·3, P adj=0·03), increased abundance of Bifidobacterium species after acidified milk intake (FC=1·4, P adj=0·04) and detection of Lactobacillus delbrueckii spp. bulgaricus (FC=7·0, P adjmicrobiota of healthy men. These observations could be relevant for dietary treatments that target 'low-grade' inflammation.

    Biomedical HIV prevention strategies, such as pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP), represent new opportunities to reduce critically high HIV infection rates among young black men who have sex with men (YBMSM). We report results of 24 dyadic qualitative interviews (N=48), conducted in Los Angeles, CA, exploring how YBMSM and their friends view PrEP and PEP. Interviews were analyzed using a grounded theory approach. Participants had widely divergent levels of knowledge about these prevention methods. Misconceptions and mistrust regarding PrEP were common, and concerns were expressed about PrEP-related stigma and the potential for gossip among peers who might assume a person on PrEP was HIV-positive. Yet participants also framed PrEP and PEP as valuable new options within an expanded "tool kit" of HIV prevention strategies that created possibilities for preventing new HIV infections, dating men with a different HIV status, and decreased anxiety about exposure to HIV. We organized themes around four main areas: (1) information and misinformation about biomedical HIV prevention; (2) expectations about PrEP, sexual behavior, and stigma; (3) gossip, disclosure, and "spreading the word" about PrEP and PEP; and (4) the roles of PrEP and PEP in an expanded HIV prevention tool kit. The findings suggest a need for guidance in navigating the increasingly complex array of HIV-prevention options available to YBMSM. Such "prevention navigation" could counter misconceptions and address barriers, such as stigma and mistrust, while helping YBMSM make informed selections from among expanded HIV prevention options.

  1. Receptivity and judgment

    2011-12-01

    Full Text Available Both judgment and receptivity are important to optimal politics, and both are important to each other. In making this argument, I use an Arendtian conception of judgment and take mindfulness as an example of receptivity. I argue that receptivity offers a needed dimension to addressing the puzzles of what makes Arendtian judgment possible, and that judgment provides a necessary complement to receptivity for action in the world. Exploring this complementary relation between judgment and receptivity also reveals a surprising similarity between what each offers to the practice of politics, in particular to freedom and the possibility of transformation. At the same time, I argue, these important contributions to politics are best understood and realized if judgment and receptivity are thought of as distinct forms of relating to the world.

    People make rapid and consequential social judgments from minimal (non-emotional) facial cues. There has been rapid progress in identifying the perceptual basis of these judgments using data-driven, computational models. In contrast, our understanding of the neural underpinnings of these judgments is rather limited. Meta-analyses of neuroimaging studies find a wide range of seemingly inconsistent responses in the amygdala that co-vary with social judgments from faces. Guided by computational models of social judgments, these responses can be accounted by positing that the amygdala (and posterior face selective regions) tracks face typicality. Atypical faces, whether positively or negatively evaluated, elicit stronger responses in the amygdala. We conclude with the promise of data-driven methods for modeling neural responses to social judgments from faces.

    The literature shows how gender mandates contribute to differences in exposure and vulnerability to certain health risk factors. This paper presents the results of a study developed in the south of Spain, where research aimed at understanding men from a gender perspective is still limited. The aim of this paper is to explore the lay perceptions and meanings ascribed to the idea of masculinity, identifying ways in which gender displays are related to health. The study is based on a mixed-methods data collection strategy typical of qualitative research. We performed a qualitative content analysis focused on manifest and latent content. Our analysis showed that the relationship between masculinity and health was mainly defined with regard to behavioural explanations with an evident performative meaning. With regard to issues such as driving, the use of recreational drugs, aggressive behaviour, sexuality, and body image, important connections were established between manhood acts and health outcomes. Different ways of understanding and performing the male identity also emerged from the results. The findings revealed the implications of these aspects in the processes of change in the identity codes of men and women. The study provides insights into how the category 'man' is highly dependent on collective practices and performative acts. Consideration of how males perform manhood acts might be required in guidance on the development of programmes and policies aimed at addressing gender inequalities in health in a particular local context.

    The aim of the study was to evaluate the relationship between body mass index (BMI) and body mass loss (BML) induced by thermal stress in a dry sauna. The study was conducted on a group of 674 sedentary students, 326 women and 348 men aged 19-20. The correlations between BMI scores and BML were determined. The subjects were placed in supine position in a dry sauna for two sessions of 10 minutes each with a 5-minute break. The influence of BMI on the amount of BML in the sauna was determined by nonlinear stepwise regression. The smallest BML was noted in underweight subjects; students with normal weight lost more weight, whereas the greatest BML was reported in overweight and obese subjects. Persons with a high BMI are at higher risk of dehydration, and they should pay particular attention to replenishing fluids during a visit to the sauna. The proposed equations for calculating BML based on a person's BMI can be useful in estimating the amount of fluids that should be replenished by both men and women during a visit to a dry sauna.

    Muscles and tendons are highly adaptive to changes in chronic loading, though little is known about the adaptative time course. We tested the hypothesis that, in response to unilateral lower limb suspension (ULLS), the magnitude of tendon mechanical adaptations would match or exceed those of skeletal muscle. Seventeen men (1.79 +/- 0.05 m, 76.6 +/- 10.3 kg, 22.3 +/- 3.8 years) underwent ULLS for 23 days (n = 9) or acted as controls (n = 8). Knee extensor (KE) torque, voluntary activation (VA), cross-sectional area (CSA) (by magnetic resonance imaging), vastus lateralis fascicle length (L(f)) and pennation angle (), patellar tendon stiffness and Young's modulus (by ultrasonography) were measured before, during and at the end of ULLS. After 14 and 23 days (i) KE torque decreased by 14.8 +/- 5.5% (P Young's modulus by 9.2 +/- 8.2% (P muscle size, architecture and function, but not in neural drive. Significant deterioration in tendon mechanical properties also occurs within 2 weeks, exacerbating in the third week of ULLS. Rehabilitation to limit muscle and tendon deterioration should probably start within 2 weeks of unloading.

We investigated whether body iron was associated with depressive symptoms, daily mood, daily tiredness, difficulty concentrating, and stress in young adult women and men. Young adult (17–25 years women (n = 562 and men (n = 323 completed the Center for Epidemiologic Studies Depression Scale, then reported negative and positive mood, and other states daily for 13 days. Non-fasting venous blood was collected to determine hemoglobin, serum ferritin and soluble transferrin receptor (to calculate body iron, C-reactive protein, and alpha-1-acid glycoprotein concentration. Regression models tested linear associations between body iron and the outcome variables, controlling for possible confounders. No associations were found between body iron and the outcome variables in women. However, higher body iron was associated with more depressive symptoms in men (3.4% more per body iron mg/kg; 95% confidence intervals (CI: 0.8%, 5.9%. In young adult women, body iron is unlikely to be associated with significant deficits in mood or depressive symptoms. However, higher body iron may be associated with more depressive symptoms in young adult men.

    Full Text Available Introduction: Plasma ghrelin is influenced by nutritional status and is thought to play a role in acute and chronic regulating of food intake and body weight. The purpose of this study was to compare GH, insulin resistance index, lipid profile, and cardiorespiratory function in obese and lean inactive young men and determine their relationships with plasma acylated ghrelin levels. Methods: Study design of this research was causal-comparative. Obese (n=19, BMI: 31.0 kg/m2 and lean (n=19, BMI: 18.5 kg/m2 young men, without experience of regular physical activity during the previous six months, were selected. After 12 h fasting (at 8 a.m., blood samples were collected to determine blood parameter levels. Also, maximal oxygen uptake (as indicator of cardiorespiratory function of subjects was assessed. Results: Insulin levels and HOMA-IR (insulin resistance index were higher, and GH, acylated ghrelin and maximal oxygen uptake levels were lower in obese men compared to lean men (P0.01. Plasma acylated ghrelin concentrations were negatively correlated to body mass, body fat percent, body mass index, insulin and HOMA-IR, and positively correlated to GH levels and maximal oxygen uptake (P0.01.Conclusion: Obese and lean inactive young men had different levels of acylated ghrelin, GH, insulin, insulin resistance index, cardiorespiratory function and body fat percent. Body fat percent, insulin, and GH levels appear to be the strongest determinant factors of acylated ghrelin levels.

    Many scholars have called for an increased focus on positive aspects of sexual health and sexuality. Using a longitudinal design with two assessments, we investigated patterns of entitlement to sexual partner pleasure and self-efficacy to achieve sexual pleasure among 295 young men and women aged 17–25 years attending one Australian university. We also tested whether entitlement and efficacy differed by gender, and hypothesized that entitlement and efficacy would be higher in older participants and those with more sexual experience. A sense of entitlement to sexual partner pleasure increased significantly over the year of the study, whereas, on average, there was no change in self-efficacy over time. At Time 1 (T1), young women reported more entitlement than young men. Age was positively associated with T1 entitlement, and experience with a wider range of partnered sexual behaviors was concurrently associated with more entitlement and efficacy and was also associated with increased entitlement to partner pleasure and increased self-efficacy in achieving sexual pleasure at T2 relative to T1. A group with the least amount of sexual experience was particularly low in entitlement and efficacy when compared to groups with a history of coital experience. There was no evidence that any association differed between young men and young women. Limitations of the study include a sample of predominantly middle class, Caucasian students at one university and the possibility that students more interested in sex and relationships, and with more sexual experience, chose to participate.

    Full Text Available In the Critique of the Power of Judgment, Kant develops a rigorous formulation of aesthetic judgments, in which he makes a sharp distinction between judgments of taste and judgments of the agreeable (both of which are, I claim, types of aesthetic judgments if only to dismiss judgments of the agreeable as worthy objects of study. Kant is primarily concerned with judgments of taste, the main example of which is judging something to be beautiful (whether it be a work of art or a natural object. He asserts that such judgments are subjective, universal, necessary, disinterested, and do not presuppose a purpose. The other type of aesthetic judgment are judgments of the agreeable, “which are the kind of judgment expressed by saying simply that one likes something or finds it pleasing.” These are judgments of what, in Kant’s words, please “the senses in sensation” as opposed to pleasing ourcognition in reflection.

    This small-scale, qualitative study examines how five young male second-generation Turkish immigrants perceive racial discrimination by ethnic Germans and to what extent this perception influences their collective identities. The typology of interactional patterns the interviewees describe as racial discrimination has four elements: a perception of distrust, a distancing gaze, denial of belonging and rule enforcement by members of the German majority. The interviewees, particularly those who are highly educated and socially mobile, identify with a common Ausländer (foreigner identity in response to experiences of discrimination. This identity is regarded a shared identity marker by immigrants of different backgrounds. It appears as a positive and affirmative identity of difference, which creates a unique type of social capital.

    Whisky (1 g/kg, 21.5% alcohol) was administered orally to healthy young adult male volunteers, and changes in the plasma concentrations of alcohol, acetaldehyde, gastrin, cholecystokinin (CCK) and serum amylase were measured over time. Values for alcohol and acetaldehyde rapidly reached a peak at 30-45 min after alcohol intake, followed by a gradual decline. The plasma gastrin concentration showed a rapid elevation, while the plasma CCK concentration did not exhibit any significant changes in the early phase after alcohol intake. Elevation of CCK was observed after 75 min, however. These results show that intake of whisky stimulates the secretion of gastrin and is associated with a later increase in CCK.

    To characterize a subgroup of arousal parasomnias associated with violent behavior in adults. A pilot study on clinical and polysomnographic data of 13 adult patients seen in a tertiary sleep center for the suspicion of arousal parasomnia associated with violence. Nine young patients (8 males 1 female) had a common pattern of abnormalities: similar 'claustrophobic' dream-like experiences and complex, vehement dream enactments; no REM sleep without atonia on polysomnography. We call this syndrome 'violent somnambulism'. The rest of the patients had alcoholic delirium, partial epilepsy, possible REM sleep behavior disorder and a single sleep walking episode provoked by a sleeping pill. Sleep related violence needs thorough diagnostic evaluation for preventing life-threatening consequences. Violent somnambulism appears to be a distinct NREM sleep-related overlap parasomnia.

Mean score of participants who had not graduated elementary school, were only 4,2. We realized that this result increased with education level. Mean score was 7,1 in participants with high school or upper education level and difference between these two groups was statistically significant (p=0,001. Participants who were born and living in the west part of the country had the highest mean score (7,8 and 7,1 respectively. Consequently, young adults who’ve been at high risk about STD, have knowledge needs, especially who live in the east region. It will be useful to have education programmes about this subject.

    Elevated lifetime prevalence rates of alcohol use disorders (AUDs) are a feature of bipolar disorder (BD). Individuals at-risk for AUDs exhibit blunted subjective responses to alcohol (low levels of response), which may represent a biomarker for AUDs. Thus, individuals at-risk for BD may exhibit low responses to alcohol. Participants were 20 unmedicated adult males who reported high rates of hypomanic experiences (bipolar phenotype participants; BPPs), aged 18 to 21 years, and 20 healthy controls matched on age, gender, IQ, BMI, and weekly alcohol intake. Subjective and pharmacokinetic responses to acute alcohol (0.8 g/kg) vs placebo administration were collected in a randomized, double-blind, cross-over, placebo-controlled, within-subjects design. BPP participants reported significantly lower subjective intoxication effects ('feel high': F=14.2, p=0.001; 'feel effects': F=8.1, p=0.008) across time, but did not differ in their pharmacokinetic, stimulant, or sedative responses. Paradoxically, however, the BPP participants reported significantly higher expectations of the positive effects of alcohol than controls. Our results suggest that unmedicated young males with previous hypomanic experiences exhibit diminished subjective responses to alcohol. These blunted alcohol responses are not attributable to differences in weekly alcohol intake, pharmacokinetic effects (eg, absorption rates), or familial risk of AUDs. These observations suggest that the dampened intoxication may contribute to the increased rates of alcohol misuse in young people at-risk for BD, and suggest possible shared etiological factors in the development of AUDs and BD.

    Acute sleep loss increases food intake in adults. However, little is known about the influence of acute sleep loss on portion size choice, and whether this depends on both hunger state and the type of food (snack or meal item) offered to an individual. The aim of the current study was to compare portion size choice after a night of sleep and a period of nocturnal wakefulness (a condition experienced by night-shift workers, e.g. physicians and nurses). Sixteen men (age: 23 ± 0.9 years, BMI: 23.6 ± 0.6 kg/m(2)) participated in a randomized within-subject design with two conditions, 8-h of sleep and total sleep deprivation (TSD). In the morning following sleep interventions, portion size, comprising meal and snack items, was measured using a computer-based task, in both fasted and sated state. In addition, hunger as well as plasma levels of ghrelin were measured. In the morning after TSD, subjects had increased plasma ghrelin levels (13%, p=0.04), and chose larger portions (14%, p=0.02), irrespective of the type of food, as compared to the sleep condition. Self-reported hunger was also enhanced (pchoice after sleep loss depend on both an individual's hunger status, and the type of food offered. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The timing of surgery in cryptorchidism has been debated for a long time. Reports on histology suggest better fertility outcomes with early surgery, whereas evidence of long-term improved fertility still lacks sound data. The aim of this study is to analyze sperm count and motility in a cohort of young men operated on during the first 2 years of life for cryptorchidism. A total of 78 young men (age, 18-26 years) surgically treated for cryptorchidism in the second year of life were recalled to evaluate testicular volume and sperm count and motility. Of the 78 young men, 51 accepted to participate to clinical and sperm evaluation. Relationship between total sperm count (TSC), sperm motility (SM), and age at surgery was investigated by Student t-test and Fisher test. Patients were divided into two groups: those patients who were submitted to surgery in their first year of life (Group A) and those patients who were submitted to surgery in their first and the second year of life (Group B). We investigated the ratio of those patients with normal sperm count to those patients with abnormal sperm count (we defined as normal TSC > 15 million and SM > 15%) and compared the mean TSC and SM in the two groups. TSC were slightly but not significantly higher in the first group (45.5 ± 15.5 million/mL vs. 36.5 ± 23.6 million/mL, p = 0.107) and SM (30.5% ± 11.3% vs. 26.5% ± 15.4%, p = 0.341). The percentage of patients with normal sperm count and motility were significantly higher in the first group: normal TSC was found in 26 of 27 patients (96.3%) in Group A versus 18 of 24 patients (75.0%) in Group B (p = 0.042), normal SM was found in 26 of 27 patients (96.3%) versus 16 of 24 patients (66.7%), respectively (p = 0.008). In the two groups, no statistically significant difference was found neither in the proportion of patients with bilateral cryptorchidism, in the position of the testes, nor in the ratio of subjects treated with hormonal

No studies have examined multiple neighborhood contexts among YMSM or the relationships between sociodemographic characteristics, psychosocial factors, social support network characteristics, health behaviors, and neighborhood concordance. In this study, we assessed spatial polygamy by determining the amount of concordance between residential, social, and sex neighborhoods (defined as boroughs in addition to examining individual-level characteristics that may be associated with neighborhood concordance. These data come from the baseline assessment of Project 18, a cohort of racially and ethnically diverse YMSM residing in the New York City metropolitan area. Participants (N = 598 provided information on their residential, social, and sex boroughs as well as information on their sociodemographic characteristics, psychosocial factors, social support network characteristics, and health behaviors (e.g., substance use and condomless sex. Descriptive analyses were conducted to examine the distribution of boroughs reported across all three contexts, i.e., residential, social, and sex boroughs. Next, concordance between: (1 residential and social boroughs; (2 residential and sex boroughs; (3 social and sex boroughs; and (4 residential, social, and sex boroughs was assessed. Finally, bivariable analyses were conducted to examine the relationships between sociodemographic characteristics, psychosocial factors, social support network characteristics, and health behaviors in relation to borough concordance. Approximately two-thirds of participants reported concordance between residential/socializing, residential/sex, and sex/socializing boroughs, whereas 25% reported concordance between all three residential

    Changes in semen quality of healthy men is a controversial issue throughout the world. It is suspected that many chemical endocrine disrupters may affect the quality of semen. Although exposure to them may be extensive in Japan, no evidence of changes in semen quality has been reported. In this study, changes in semen volume and sperm counts were analyzed over 20 years in the Sapporo area of Japan. Semen volume and sperm counts were measured in 254 and 457 normal, healthy volunteers who lived in the Sapporo area in 1975-1980 and 1998, respectively. Posters and handbills were used to recruit participants in both studies. Semen samples were collected by masturbation after 3 days or more of abstinence. There was no change in semen volume between 1975-1980 and 1998. Mean sperm counts were 70.9 +/- 47.3 x 10(6)/mL in 1975-1980 and 79.6 +/- 49.3 x 10(6)/mL in 1998. Sperm counts did not decline over about 20 years. No significant correlation between age and sperm counts was recognized in either study. The rates of subjects with oligozoospermia and azoospermia were the same in both studies. In the 1975-1980 study, 34 of 254 (13.4%) participants had a child, and in the 1998 study, 51 of 457 (11.2%) participants had a child. Mean sperm count was significantly (P Sapporo area of Japan over 20 years. However, selection bias in the recruitment of volunteers and the issue of variable abstinence might have affected the results of these studies. Therefore, well-designed prospective studies should be performed in several different regions to extrapolate our results on sperm counts to healthy, young Japanese men in general.

    Full Text Available Muscle hypertrophy following resistance training (RT involves activation of myofibrillar protein synthesis (MPS to expand the myofibrillar protein pool. The degree of hypertrophy following RT is, however, highly variable and thus we sought to determine the relationship between the acute activation of MPS and RT-induced hypertrophy. We measured MPS and signalling protein activation after the first session of resistance exercise (RE in untrained men (n = 23 and then examined the relation between MPS with magnetic resonance image determined hypertrophy. To measure MPS, young men (24±1 yr; body mass index  = 26.4±0.9 kg•m² underwent a primed constant infusion of L-[ring-¹³C₆] phenylalanine to measure MPS at rest, and acutely following their first bout of RE prior to 16 wk of RT. Rates of MPS were increased 235±38% (P<0.001 above rest 60-180 min post-exercise and 184±28% (P = 0.037 180-360 min post exercise. Quadriceps volume increased 7.9±1.6% (-1.9-24.7% (P<0.001 after training. There was no correlation between changes in quadriceps muscle volume and acute rates of MPS measured over 1-3 h (r = 0.02, 3-6 h (r = 0.16 or the aggregate 1-6 h post-exercise period (r = 0.10. Hypertrophy after chronic RT was correlated (r = 0.42, P = 0.05 with phosphorylation of 4E-BP1(Thr37/46 at 1 hour post RE. We conclude that acute measures of MPS following an initial exposure to RE in novices are not correlated with muscle hypertrophy following chronic RT.

    There is mounting evidence that single administrations of glucocorticoids may acutely reduce human fear. We previously reported that administration of cortisol acutely reduced non-spatial selective attention to fearful faces and likewise reduced preferential processing of fearful faces in a spatial working memory task. Here we report the acute effects of 40 mg cortisol (administered in a double-blind, placebo-controlled crossover design) on a different experimental task for measuring threat-selective attention. Twenty healthy young males had to localize a target which was presented in a peripheral location that was either gazed at or not by a preceding dynamic happy or fearful face. This reliable method has been used repeatedly to demonstrate fear-driven selective attention. Present results showed that after placebo, as usual, the fearful gaze cues caused stronger orienting of attention than happy faces. Cortisol abolished this typical anxious response pattern, but only in low anxious participants. These data provide evidence that cortisol acutely influences also spatial threat-selective attention. Possible neuroendocrine mechanisms are discussed. Copyright (c) 2009 Elsevier Inc. All rights reserved.

    Studies of the process of human mate selection and attractiveness have assumed that selection favours morphological features that correlate with (genetic) quality. Degree of masculinity/femininity and fluctuating asymmetry (FA) may signal (genetic) quality, but what information they harboured and how they relate to fitness is still debated. To study strength of associations between facial masculinity/femininity, facial FA, attractiveness and physical strength in humans. Two-hundred young males and females were studied by measuring facial asymmetry and masculinity on the basis of frontal photographs. Attractiveness was determined on the basis of scores given by an anonymous panel, and physical strength using hand grip strength. Patterns differed markedly between males and females and analysis method used (univariate vs multivariate). Overall, no associations between FA and attractiveness, masculinity and physical strength were found. In females, but not males, masculinity and attractiveness correlated negatively and masculinity and physical strength correlated positively. Further research into the differences between males and females in associations between facial morphology, attractiveness and physical strength is clearly needed. The use of a multivariate approach can increase our understanding of which regions of the face harbour specific information of hormone levels and perhaps behavioural traits.

A double-blind, placebo-controlled, randomized trial was conducted to evaluate the effect of sublingual nucleotides (50 mg/day administered for 14 days in thirty young healthy physically active males, on endurance performance and immune responses. Fasting white blood cell count, natural killer cells (NKC number, NKC cytotoxic activity, and serum immunoglobulin (IgA, IgM, IgG, and time to exhaustion, peak rate of perceived exertion, peak heart rate, and peak running speed during the exercise test were measured at baseline (day 0 and post-intervention (day 14. Time to exhaustion, as well as serum immunoglobulin A and NKC cytotoxic activity, were significantly higher at day 14 (p < 0.05 in participants supplemented with nucleotides compared with those who consumed placebo. No significant differences in other parameters were observed between groups at post-intervention. No volunteers withdrew before the end of the study nor reported any vexatious side effects of supplementation. The results of the present study suggest that sublingual nucleotides may provide pertinent benefit as both an ergogenic and immunostimulatory additive in active males.

    Objective: To determine the effects of electrical stimulation (ES) on oxygen uptake (VO2) kinetics and delta efficiency (DE) during gradual exercise. The hypothesis was that ES would attenuate the VO2-workload relation and improve DE. Methods: Fifteen healthy, untrained men (mean (SD) age 22 (5) years) were selected. Ten were electrostimulated on both quadriceps muscles with a frequency of 45–60 Hz, with 12 seconds of stimulation followed by eight seconds recovery for a total of 30 minutes a day, three days a week for six weeks. The remaining five subjects were assigned to a control group. A standardised exercise test on a cycle ergometer (ramp protocol, workload increases of 20 W/min) was performed by each subject before and after the experimental period. The slope of the VO2-power output (W) relation (ΔVO2/ΔW) and DE were calculated in each subject at moderate to high intensities (above the ventilatory threshold—that is, from 50–60% to 100% VO2max). Results: The mean (SEM) values for ΔVO2/ΔW and DE had significantly decreased and increased respectively after the six week ES programme (p<0.05; 9.8 (0.2) v 8.6 (0.5) ml O2/W/min respectively and 27.7 (0.9) v 31.5 (1.4)% respectively). Conclusions: ES could be used as a supplementary tool to improve two of the main determinants of endurance capacity, namely VO2 kinetics and work efficiency. PMID:12663356

    Socioeconomic status (SES) is often inversely related to health outcomes and is likely to play a role in the use of psychoactive substances among young individuals, although little consensus exists on the association between SES and substance use. The purpose of the study was to determine the association of three SES indicators (perceived family income, education level of participants, and parental education level) with past year use of alcohol, tobacco, cannabis, other illicit drugs and non-medical use of prescription drugs (NMPD) among Swiss young men. Population-based cross-sectional study of 5,702 men at mean age twenty. Associations between SES indicators and substance use were assessed with regression models adjusted for age and linguistic region. Participants with average or below average perceived family income were less likely to report any use of alcohol (OR = O.75) but more likely to use tobacco daily (OR = 1.31) and cannabis weekly (OR = 1.27) compared to those with perceived above average family income. Participants whose parents had only achieved obligatory education were less likely to engage in any use of alcohol (OR = 0.30), monthly risky single occasion drinking (RSOD, defined as 6 or more drinks per occasion) (OR = 0.48), any use of cannabis (OR = 0.53) and other illicit drugs (OR = 0.58), whereas those whose parents had only achieved secondary education were less at risk of engaging in cannabis (OR = 0.66 for any use and OR = 0.77 for more than once a week use) and other illicit drugs (OR = 0.74) use, compared to those whose parents had achieved tertiary education. Compared to participants who completed secondary or tertiary education, those who completed only obligatory education reported a higher risk of tobacco (OR = 1.18 for any use, OR = 1.31 for daily use), cannabis (OR = 1.23 for any use, OR = 1.37 for more than once a week use), and other illicit drugs (OR = 1.48) use.

    Population studies have shown that a high proportion of Nordic men may have so poor semen quality that they can be classified as sub-fertile according to international standards. A question is whether the Nordic data are specific for the Nordic countries or they should be seen as an expression of a general trend in Europe. We therefore carried out a prospective study of semen quality of young men raised in the former East Germany (Leipzig) and West Germany (Hamburg). To enable inter-regional comparisons, we utilized a common European research protocol previously used in studies in the Nordic-Baltic region. Three hundred and thirty-four young men representative of the general population from Hamburg, and 457 from Leipzig delivered semen samples, underwent physical examinations and provided information on life-style and reproductive health parameters. The study period in Hamburg was February 2003--July 2004, and in Leipzig July 2003--April 2005. No significant differences were observed in sperm concentration (median 46, 42, and 44 million/mL for men from Hamburg, Leipzig and the combined Hamburg-Leipzig group respectively) or total sperm count (154,141 and 149 million), whereas the differences for morphologically normal spermatozoa (9.4 and 8.4%) and motile spermatozoa (67 and 81%) were significantly different. Previously published studies have shown reduced fertility with decreasing sperm concentrations below 40-55 millions/mL and normal sperm morphology below 9-19%. Thus, a large fraction of young German men seem to have impaired semen quality that may reduce their natural fertility. However, it remains to be investigated to what extent poor semen quality contributes to the low German fertility rates.

    The purpose of this study was to examine the acute effects of constant-angle (CA) and constant-torque (CT) static stretching on passive stiffness of the posterior hip and thigh muscles in healthy, young and old men. Fifteen young (25±3 years) and 15 old (71±4 years) men underwent 2 passive straight-leg raise (SLR) assessments before and after 8 min of CA and CT stretching using an isokinetic dynamometer. Passive stiffness was calculated during each SLR as the slope of the final 10% of the angle-torque curve. The results indicated that passive stiffness decreased from pre- to post-stretching for both treatments (P≤0.001-0.002) and age groups (P≤0.001-0.046); however, greater decreases were observed for the CT than the CA stretching (P=0.045) and for the old than the young men (Pstretching. These findings suggest that holding stretches at a constant tension may be a more effective strategy for altering passive stiffness of the posterior hip and thigh muscles. The greater stretch-induced stiffness decreases observed for the older men provide support that acute static stretching may be particularly effective for reducing stiffness in the elderly. As a result, it may be advantageous to prescribe static stretching prior to exercise for older adults, as this may be used to elicit substantial declines in passive stiffness, which could help reduce the risk of subsequent injury events in this population.

    We report an unusual presentation of multiple endocrine neoplasia type 1 (MEN 1) in a young woman who was subsequently proven to have a novel mutation of the MEN1 gene. The young patient, aged 25 years, was investigated for abdominal discomfort and left upper abdominal pain. Her family history was unremarkable, except an unknown disorder of her father causing early death. Abdominal ultrasonography (USG) and computed tomography revealed a giant pancreatic tumor measuring 10 cm in diameter. The diagnosis of a clinically nonfunctioning pancreatic neuroendocrine tumor was established by clinical and other studies, including USG-guided aspiration biopsy and octreotide scintigraphy, and the patient underwent a distal pancreatectomy. Histology proved a well-differentiated multinodular neuroendocrine tumor of the pancreas. During surgery, a subcutaneous lipoma was also removed from the abdominal wall. Two years later, the patient developed primary hyperparathyroidism, and two enlarged parathyroid glands were surgically removed. Magnetic resonance imaging of the pituitary gland was normal. Screening for MEN1 gene mutation by temperature gradient gel electrophoresis revealed heterozygosities in exons 3, 8, and 9, while direct sequencing indicated a novel germline mutation (C354X) resulting in a stop codon in exon 8 and polymorphisms in exon 3 (R171Q) and exon 9 (D418D and L432L). Genetic screening revealed no mutation in living family members. Our unusual case suggests that a multinodular pancreatic neuroendocrine tumor in a young patient may justify screening for MEN 1 syndrome, even in the absence of other endocrinopathy or family history.

    Peer pressure (PP) toward misconduct is a well-known risk factor for substance use. However, the way it interacts with social factors and the associations of the aspects of PP other than PP toward misconduct have been understudied. This study examined the associations of three aspects of PP with risky substance use and tested whether the associations of PP toward misconduct were moderated by social factors. A representative sample of 5,680 young Swiss males completed a questionnaire assessing risky alcohol, cigarette, and cannabis use, PP toward misconduct, toward peer involvement, and toward peer conformity, as well as social support (SS) and neighbourhood cohesion. Multinomial logistic regression models were used. PP toward misconduct was positively associated with all substance use outcomes. The PP toward misconduct-risky alcohol use association was stronger in individuals reporting high than in those reporting low levels of PP toward peer involvement, SS, and neighbourhood cohesion. The PP toward misconduct-risky cannabis use association was stronger in individuals reporting high than in those reporting low levels of SS and neighbourhood cohesion. The PP toward misconduct-smoking association was stronger in individuals reporting high than in those reporting low levels of PP toward peer involvement. The risk for substance use associated with PP toward misconduct varies as a function of social factors. Being well connected with others (high level of PP toward peer involvement and SS), and living in a cohesive neighbourhood may amplify the risk for risky substance use associated with PP toward misconduct.

    Background Traditional forms of masculinity strongly influence men's and women's wellbeing. Objective This study has two aims: (i) to explore notions of various forms of masculinities in young Nicaraguan men participating in programs addressing sexual health, reproductive health, and/or gender equality and (ii) to find out how these young men perceive their involvement in actions aimed at reducing violence against women (VAW). Design A qualitative grounded theory study. Data were collected through six focus groups and two in-depth interviews with altogether 62 young men. Results Our analysis showed that the informants experienced a process of change, labeled ‘Expanding your mind’, in which we identified four interrelated subcategories: The apprentice, The responsible/respectful man, The proactive peer educator, and ‘The feminist man’. The process showed how an increased awareness of gender inequities facilitated the emergence of values (respect and responsibility) and behavior (thoughtful action) that contributed to increase the informant's critical thinking and agency at individual, social, and political levels. The process was influenced by individual and external factors. Conclusions Multiple progressive masculinities can emerge from programs challenging patriarchy in this Latin American setting. The masculinities identified in this study show a range of attitudes and behaviors; however, all lean toward more equitable gender relations. The results suggest that learning about sexual and reproductive health does not directly imply developing more gender-equitable attitudes and behaviors or a greater willingness to prevent VAW. It is paramount that interventions to challenge machismo in this setting continue and are expanded to reach more young men. PMID:22870066
