Discussion. The epidemic of HIV/STD among MSM is severe, and the prevalence of risk sexual behaviors was at a high level among MSM in China. The risk factors for HIV/STD and factors associated with DAI reported in this study give some insights towards designing relevant prevention programs. The simplicity and feasibility of our effective intervention, enhanced VCT, makes it possible for this to be incorporated into standard VCT procedures. Further translational research is needed to investigate its effectiveness in the real-world setting. / Introduction. Men who have sex with men (MSM) have become the main group for HIV transmission in China in 2009. There have been many epidemiological cross-sectional studies targeting MSM in China in recent years. These provide limited data compared with cohort studies, which can describe the rate at which HIV/STD are spreading in a target population. Moreover, there is a dearth of intervention studies which are theory-based with rigorous research methodology in China. Last but not least, research is needed on sexual behaviors and their determinants, including cognitions from health behavioral theories, event-specific factors, etc. / Objectives. This study investigated the prevalence and incidence of HIV/STD, as well as their associated risk factors among MSM in Nanjing, China. It also explored the prevalence of unprotected anal sex (UAI) and the associated factors, including cognitions from health behavioral theories and event-specific factors. In addition, this is also one of the first studies to examine the efficacy of a randomized control trial (RCT) designed intervention, to use enhanced voluntary counseling and testing (VCT) to reduce UAI among MSM in China. / Results. The RDS-adjusted HIV, syphilis and HCV prevalence were respectively 7.3%, 14.4% and 0.2% at baseline. Of the 397 MSM who were found to be HIV seronegative at baseline, 286 (72.0%) retested at Month 6. HIV, syphilis and HCV incidence were respectively 5.12, 7.58 and 0 per 100 person-years (PY). Recruiting male sex partners mostly at saunas was the risk factor associated with being HIV seropositive at baseline (OR=3.84) and undergoing HIV/syphilis seroconversion at Month 6 (RR=2.351RR=6.72). In the RCT study, participants in the Intervention Group reported significantly less risk than those in the Control Group (UAI with any male sex partners: 48.4% vs. 66.7%;UAI with regular male sex partners: 52.2% vs. 68.9%) at Month 6. Furthermore, Perceived Behavior Control showed a significant association with DAI with both regular (AOR=0.42) and casual partners (AOR=O.73). / Subjects and Methods. A cohort study and randomized control trial were conducted. Out of 416 MSM approached by respondent driven sampling (RDS), 397 HIV negative participants were recruited to the HIV/syphilis/HCV cohort, and they were invited to return for a follow-up visit at Month 6. A subsample from the baseline cohort consisting of 307 MSM, was randomly assigned to either the Intervention Group (enhanced VCT) or the Control Group (standard VCT). Evaluation was conducted at Month 6. Both baseline and Month 6 visits consisted of VCT service and interviewing. Statistical methods such as Chi-square test, logistic regression and Poisson regression were used in this study. / Hao, Chun. / Adviser: Joseph TF Lan. / Source: Dissertation Abstracts International, Volume: 73-04, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2011. / Includes bibliographical references (leaves 166-179). / Electronic reproduction.

The impact of childhood sexual interaction on current psychological functioning in a male forensic population

Rees, Neil January 1998 (has links)
Little research attention has been paid to forensic populations of male survivors of childhood sexual abuse (CSA), where it is understood that prevalence rates are high. This study aimed to survey a sample of 40 men in a maximum security hospital who had experienced childhood sexual interaction (CSI). The study profiled the psychological functioning of the sample through a number of standardised measures and a semi-structured interview. In addition, the meanings that the men attached to their childhood sexual experiences,t heir 'constructions' of them, were also examined, along with their self-report of distress related to these experiences. The limited research conducted with male survivors suggests that men tend to construct CSI in more positive or neutral terms than female survivors, and are less likely to report distress related to the experience. However, men's experiences of CSI have still shown similar levels of association with psychological symptomatology in adulthood. This apparent discrepancy has been understood in terms of male socialisation. The predictions that the men in this sample would show high levels of psychological symptomatology, which would be associated with the characteristics of CSI, and that the majority of them would describe positive or neutral constructions of CSI, and would tend to report no distress related to their experiences, were supported in this study. The implications of these findings are discussed. Overall, it is stressed that in order to fully understand the impact of CSA on males, and to provide appropriate approaches to interventions, a fuller appreciation of the role of male socialisation must be achieved.

O gênero vai à roça : a presença de professores homens na educação no/do campo

Xavier, Antonio Jeferson Barreto January 2017 (has links)
O presente estudo teve como objetivo analisar as questões de gênero e sexualidade suscitadas a partir da presença de professores homens que atuam nos Anos Iniciais do Ensino Fundamental em duas roças no interior da Bahia. Ao longo do processo de generificação das profissões, diversos ofícios foram feminizados. Contudo, o magistério se destaca entre os demais, pois ainda hoje há uma acentuada demarcação dessa profissão como ideal para as mulheres. A pesquisa situa-se nos campos teóricos dos estudos de gênero, estudos culturais e pós-estruturalismo e estudos das masculinidades. A roça foi compreendida na pesquisa enquanto um lugar generificado e sexualizado que apresenta seus próprios discursos nas construções de gênero e sexualidade. Embora não seja o foco central da pesquisa a Educação do/no Campo também é abordada na dissertação, uma vez que é nessa modalidade de ensino que as duas escolas pesquisadas estão inseridas. A metodologia escolhida foi a etnografia e como procedimentos de produção de dados foram utilizadas a observação-participante, a elaboração do caderno de anotações e entrevistas-semiestruturadas Foram entrevistados dezesseis adultos, sendo pais, professores/as gestores/as e quatro crianças, duas de cada escola. Além das conversas informais com diversos atores sociais da comunidade escolar e rural, mas os três professores homens são considerados os principais informantes da pesquisa. A partir das análises realizadas é possível concluir que a presença dos professores homens na docência com crianças ainda desperta questionamentos, tensões e pânicos morais. Foi possível observar que essas construções discursivas refletem nas suas aulas e na relação com as crianças. A partir dos dados produzidos emergiram três categorias analíticas centrais: o medo da pedofilia, os questionamentos em torno das masculinidades dos professores e as práticas pedagógicas que buscam um distanciamento de qualquer elemento considerado culturalmente como feminino. Por meio de diferentes discursos esses homens ao optarem por uma profissão historicamente feminizada são vistos como fora do lugar. / The current paper aimed to analyze gender and sexuality issues aroused from the presence of two male teachers who work in the First Years of Elementary School in two different sites in the countryside in the State of Bahia. Along the gender formation process present in the occupations, several ones were considered feminine. However, the teaching stands out from the others, once even today there is a pronounced demarcation of this profession as ideal for women. The present research is located in the theoretical fields of gender studies, cultural studies and also post-structuralism. The countryside was understood in the research as a gendered and sexualized place which presents its own discourses in the construction of gender and sexuality. Although it is not the central focus of this research, the Education in/of the countryside is also approached in the dissertation, once it is in this teaching modality that the two researched schools are inserted. The methodology chosen was the ethnography and as the data production procedures the participative-observation was utilized, as well as the elaboration of a diary for notes and also semi-structured interviews Sixteen adults were interviewed, among parents, teachers, school administrators as well as four children, two from each school. Besides the informal conversations with several social actors from the school community and the rural community, the three male teachers were considered the main informers of the research. From the carried analyzes it is possible to conclude that the presence of male teachers within the context of the teaching practicing with children still provokes questionings, tensions and moral panic. It was possible to observe that such discursive constructions are reflected in their classes and in their relation with the children. From the produced data, three central analytic categories emerged: the fear of pedophilia, the questionings around the teachers‟ masculinities and the pedagogical practices which search for a distance from any element culturally considered as feminine. By means of different discourses, these men, by opting for a historically feminine profession are seen as out of their places.

Understanding male athlete sexual aggression: "masculinity, sexual aggression, and athletic participation"

Walker, Earl Eugene, Jr January 2003 (has links)
Thesis (Ed.D.)--Boston University / PLEASE NOTE: Boston University Libraries did not receive an Authorization To Manage form for this thesis or dissertation. It is therefore not openly accessible, though it may be available by request. If you are the author or principal advisor of this work and would like to request open access for it, please contact us at open-help@bu.edu. Thank you. / Sexual victimization is a serious public health issue in the United States, particularly on its college campuses. Several attempts have been made to identify groups at high risks for exhibiting sexually aggressive behaviors. In the same vein, this study examines the relationship between athletic participation and sexual aggression with a focus on wrestlers. The author hypothesized that wrestling participation and athletic participation would be positively correlated with sexual aggression. However, it was also hypothesized that this relationship would be mediated by masculinity (gender role conflict) and masculinity related variables (sexual entitlement and competitiveness). A one-way Analysis of Variance (ANOVA) followed by post hoc tests found no significant difference between Wrestlers and Non-Athletes on levels of sexual aggression at the Q = .05 level. Similarly, no significant differences were found between Other Athletes and Non-Athletes at the same alpha level. However, a near significant difference (Q = .058) was found between Multisport Athletes and Other Athletes. A regression analysis was also conducted, which found sexual entitlement, wrestling participation, and drinking intensity as significant predictors of sexual aggression. However, a partial correlation analysis found no mediating effects between wrestling participation and sexual aggression when sexual entitlement and drinking intensity were held constant. Recommendations for rape prevention programs were made based on these findings. / 2031-01-01

Inside a gay world : a heuristic self-search inquiry of one gay man's experience of a 'cultic' gay male friendship group

Holmes, Jason Kenneth January 2018 (has links)
This thesis is a Heuristic Self-Search Inquiry (HSSI) that explores the personal experience of one gay man's participation in a gay male friendship group whose culturally constructed sense of being gay, characterised by specific places, customs and practices the researcher considers 'cultic'. The study is undertaken through the researcher who found himself outside a closed group of emotionally intimate gay friends, which represented an entire world. Using the HSSI model created by Sela-Smith (2002), this profoundly personal qualitative study considers the researcher's internal experiencing as the primary source of knowledge. Material from online images, academic papers and personal writing of the inquirer's lived experience of the research topic provided for periods of contemplative incubation and illumination, typical of HSSI. The output was the depiction of six emergent themes that highlight the qualities and nuances of the topic: pain, frustration, mistrust, joy, disgust and confusion. The other main findings are: this gay male friendship group developed characteristics of a symbolically enclosed cultic institution; that gay men are susceptible to forming cultic relationships; and a depth of distress experienced when intimate friendships between gay men fail. The findings finish by offering a creative synthesis, which captures the resultant integrated understanding of the experience in the form of a short story. Recommendations are made for counselling professionals to trouble their understanding of gay male friendship groups, and for public and third sector organisations working with Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ) identifying peoples to begin discussing interpersonal issues inside LGBTQ populations.

Male Weight Control: Crowdsourcing and an Intervention to Discover More

Rounds, Tiffany 01 January 2019 (has links)
Men and women have similar rates of obesity but the combined prevalence of overweight and obesity is higher among men. Men who are overweight are a high-risk group for many obesity-related chronic diseases, as they are more likely to carry excess weight in the abdomen, which is generally more harmful than weight stored in the lower body. Men are also less likely than women to perceive themselves as overweight, and thus are less likely to initiate weight loss through organized weight loss programs. On average, less than 27% of weight loss trial participants have been men. Internet-based research is a low-cost, efficient way to produce novel hypotheses related to weight loss that may have previously escaped weight loss professionals. Additionally, incentives are an effective tool to motivate behavior change, and there is ample evidence to support the use of incentives to encourage many health-promoting behaviors, such as weight loss. The purpose our initial study was to facilitate intervention development by using crowdsourcing to detect unexpected beliefs and unpredicted barriers to male weight loss. The aim of our main study was to evaluate the impact of financial incentives to facilitate weight loss in men, delivered as part of a weight loss intervention. Two separate studies were conducted. In the first project, participants were recruited to a crowdsourcing survey website which was used to generate hypotheses for behaviors related to overweight and obesity in men. Participants provided 21,846 responses to 193 questions. While several common themes seen in prior research were revealed such as previous health diagnoses and physical activity participation, other potential weight determinants such as dietary habits, sexual behaviors and self-perception were reported. Crowdsourcing in this context provides a mechanism to further investigate perceptions of weight and weight loss interventions in the male population that have not previously been documented. These insights will help guide future intervention design. For the main project, a randomized trial compared the Gutbusters weight loss program (based on the REFIT program) alone with Gutbusters with escalating incentives for successful weight loss. The six-month intervention was conducted online with weekly in-person weight collections for the first 12 weeks. Gutbusters encouraged participants to make six 100-calorie changes to their daily diet, utilizing a variety of online lessons targeting specific eating behaviors. Measures included demographic information, height, weight, waist circumference, and body fat percentage. Participants (N=102, 47. 0± 12. 3 yrs old, 32. 5 kg/m2, 80. 4% with at least two years of college) were randomized in a 1:1 ratio to Gutbusters or Gutbusters+Incentive. Significantly more Gutbusters+Incentive participants lost at least 5% of their baseline weight compared to the Gutbusters group at both 12 and 24 weeks. Similar to the aforementioned REFIT program, Gutbusters participants were able to achieve clinically significant weight loss. The Gutbusters+Incentive achieved greater rates of weight loss than the Gutbusters alone group, further supporting the value of incentives in promoting health behaviors.

Predictors of Mastectomy in Male Breast Cancer

Opara, Esther 01 January 2017 (has links)
Male breast cancer (MBC) is rare, and research on the predictors of MBC has been limited because of inadequate funding in and outside of the United States. One goal of this study was to eradicate the stereotyping of breast cancer as a female disease. The emergence of medical technology and education to benefit the public will help to ensure greater health awareness at the individual, community, and global levels. The purpose of this study was to understand the influence of the predictors of age; race (Black, White, and Other); and grade of cancer (I, II, or III) on the outcome of mastectomy in MBC. The study was guided by the social determinants of health model. A quantitative approach was used to analyze archival data from 2011 to 2013 in the Surveillance Epidemiology and End Results (SEER) database using SPSS v.23. Data from 427 MBC patients ages 18 years and older from the United States comprised the sample. The SEER data were analyzed using logistic regression analysis. Results showed that of the 427 cases of MBC that were analyzed, 55 had a diagnosis of Grade I, 190 had a diagnosis of Grade II, and 182 had a diagnosis of Grade III. For 3 years, 116 men had undergone mastectomy. Grade I cancer, Grade II cancer, and Grade III cancer were statistically insignificant predictors of mastectomy; however, age, race was a statistically significant predictor of mastectomy among White men with MBC. The results will contribute to social change initiatives by educating the public about the predictors of mastectomy in MBC patients. The results also will increase the current knowledge base by informing the public, clinical professionals, and patients about the relationship of the predictors of age; race; and grade of cancer (I, II, or III) on the outcome of mastectomy in MBC.
