目的了解深圳市男男性行为人群（MSM）自愿咨询检测（VCT）的情况及其影响因素。方法对2005-2011年深圳市MSM接受VCT服务等的资料,进行Cochran-Armitage趋势检验和Logistic回归分析。结果 2005-2011年,共有5 232名MSM接受VCT服务,338人（6.46%）确认感染艾滋病病毒（HIV）,1 097人（20.97%）确认感染梅毒,既往VCT接受率呈逐年增加趋势（z=-15.479 8,P〈0.000 1）。单因素和多因素分析结果均显示,年龄≥30岁、大专及以上文化程度、曾经献血、性取向为同性恋及双性恋、梅毒感染阳性,是MSM既往接受VCT服务的促进因素;职业为待业/无业、工人和学生,是既往接受VCT服务的阻碍因素。结论应有针对性地对MSM进行VCT宣传教育,并充分发挥性病门诊在该人群VCT服务中的作用。     

Willingness to use couples voluntary counseling and testing services among men who have sex with men in seven countries

The willingness of male-male dyads to use couples voluntary HIV counseling and testing (CVCT) has not been previously investigated globally among men who have sex with men (MSM). Using online advertisements, data were collected from 3245 MSM in seven countries who were ≥18 years of age and had ≥1 male sex partner in the previous 12 months. The analysis examined associations between individual characteristics and willingness to utilize CVCT. The willingness to utilize CVCT was compellingly high, ranging from 79% in Australia and UK to 90% in Brazil. Older MSM and those who reported not knowing their sero-status reported lower odds of willingness to use CVCT. The relationship between being in a relationship and willingness to use CVCT varied across countries, perhaps reflecting varied local understandings of the nature and content of CVCT. Further work is required to examine willingness to use CVCT among a more heterogeneous population of MSM, and to examine how CVCT services are locally perceived in order to provide information vital for the development of locally appropriate messages to promote CVCT for MSM.     

Social vulnerability and HIV testing among South African men who have sex with men

This study examined whether social vulnerability is associated with HIV testing among South African men who have sex with men (MSM). A community-based survey was conducted with 300 MSM in Pretoria in 2008. The sample was stratified by age, race and residential status. Social vulnerability was assessed using measures of demographic characteristics, psychosocial determinants and indicators of sexual minority stress. Being black, living in a township and lacking HIV knowledge reduced MSM's likelihood of ever having tested for HIV. Among those who had tested, lower income and not self-identifying as gay reduced men's likelihood of having tested more than once. Lower income and internalized homophobia reduced men's likelihood of having tested recently. Overall, MSM in socially vulnerable positions were less likely to get tested for HIV. Efforts to mitigate the effects of social vulnerability on HIV testing practices are needed in order to encourage regular HIV testing among South African MSM.     

Depression and anxiety among HIV-positive men who have sex with men and men who have sex with women in China

ABSTRACT

China is experiencing an emerging HIV epidemic among men who have sex with men (MSM). Minority stress theory posits that marginalized populations experience additional stress, which influences experiences of psychological distress and health outcomes. This study aimed to understand psychological distress of MSM relative to men who have sex with women (MSW) in an urban Chinese setting. Cross-sectional survey data were collected from 162 HIV-positive Chinese men receiving HIV treatment at Beijing’s Ditan Hospital. Multiple linear regression with imputation was used to identify correlates of psychological distress. Relative to MSW, MSM were younger, more educated, and less likely to be in a relationship or have children. While both groups reported clinically elevated levels of depression and anxiety, sexual behavior was not associated with either outcome. Higher endorsement of depression symptomology was associated with worse reported physical health (β?=??1.37, p?<?.05) and greater endorsement of maladaptive coping (β?=?2.39, p?<?.05), whereas higher endorsement of anxiety symptomology was associated with greater endorsement of adaptive coping (β?=?0.78, p?<?.05), diminished physical health (β?=??0.86, p?<?.05), and a high school or greater level of education (β?=?4.13, p?<?.05). These findings suggest that interventions targeting coping strategies may address psychological distress among HIV-positive Chinese men.     

HIV-testing of men who have sex with men: variable testing rates among clinicians

High HIV testing coverage of high-risk populations is required to reduce the number of HIV-infected individuals unaware of their status. The aim of this study was to determine HIV testing rates among men who have sex with men (MSM) attending a sexual health service, including the impact of the treating clinician on HIV testing rates. Factors associated with HIV testing of MSM attending the Melbourne Sexual Health Centre for the first time between 2003 and 2009 were determined, including testing rates for individual treating clinicians. Overall, 78% of 4425 men were tested for HIV. Clinician HIV testing rates were higher among nurses (median 89%; range 77-95%) than doctors (median 73%; range 45-88%) with significant differences between individual physicians (P < 0.001). Lower testing among doctors was independent of reported sexual risk and time since the last HIV test. Substantial differences in HIV testing rates between clinicians were evident with low testing by some. Increasing HIV testing rates among high-risk groups require engagement not only of individuals at risk but also awareness among health-care providers who perform HIV testing.

HIV testing practices among men who have sex with men in Buenos Aires,Argentina

The objective of the study was to explore HIV-testing practices among men who have sex with men (MSM) in Buenos Aires, Argentina, in light of current international health guidelines that recommend frequent HIV testing for MSM who engage in high-risk behavior. Participants, who were recruited using respondent-driven sampling (RDS), were 500 mostly young, nongay-identified MSM of low socioeconomic status, high levels of unemployment, living mainly in the less-affluent areas surrounding Buenos Aires, and lacking health insurance. They provided blood samples for HIV testing and responded to a Computer Assisted Self Interview. Fifty-two percent had never been tested for HIV, and 20% had been tested only once; 17% were found to be HIV infected, of whom almost half were unaware of their status. Main reasons for never having tested previously were: not feeling at risk, fear of finding out results, and not knowing where to get tested. Among those previously tested, men had been tested a median of 2 times with their most recent test having occurred a median of 2.7 years prior to study enrollment. Of those who had not tested positive before entering the study, only 41% returned for their results. HIV testing was infrequent and insufficient for early detection of infection, entry into treatment, and protection of sexual partners. This was particularly the case among nongay-identified MSM. Testing campaigns should aim to help MSM become aware of their risk behavior, decrease fear of testing by explaining available treatment resources and decreasing the stigma associated with HIV, and by publicizing information about free and confidential testing locations. Rapid HIV testing should be made available to eliminate the need for a return visit and make results immediately available to individuals who are tested.     

Pre-exposure prophylaxis sorting among men who have sex with men

Factors such as race, masculinity, and sexually transmitted infections have been documented to influence partner selection in men who have sex with men (MSM). Pre-exposure prophylaxis (PrEP) has received mixed evaluations as a responsible step in HIV prevention and as an enabler of risker sexual practices. PrEP may consequently serve as an additional factor in partner choice. We examine the role that PrEP use and “promiscuity” play in affiliation and dating decisions by men who have sex with men with different HIV and PrEP stati. We invited 450 MSM across the United States from a smartphone geo-locating sex application to complete a survey of which 339 successfully finished the task. The survey contained vignettes of fictional men who were promiscuous or monogamous and either taking PrEP or not. Participants provided responses on whether to affiliate with these characters in three social domains: as friends, dates, or sex partners. Neither PrEP nor promiscuity influenced friendship choices. There was a preference for dating monogamous characters. Critically, PrEP influenced sexual affiliations for HIV negative individuals who showed a preference for PrEP-using characters. The pattern of results provides quantitative evidence for PrEP-based sexual sorting aimed at reducing risk of HIV transmission.     

Factors associated with sexually transmitted infection testing among men who utilize an internet-based men who have sex with men community

Public health messaging encourages men who have sex with men (MSM) to be tested for sexually transmitted infections (STI) and HIV at least yearly, and more frequently depending on sexual behaviors. However, despite engaging in a range of sexual behaviors, many MSM do not participate in regular STI testing. The objective of this study was to understand factors associated with STI testing among a nonclinic-based population of men accessing an Internet-based social and sexual networking site. We asked 25,736 men to complete a comprehensive behavioral and health assessment after being recruited from an Internet site popular among men seeking social or sexual interactions with other men. Analyses were performed using multivariate logistic regression with effects significant at p?相似文献   

Risk of HIV infection attributable to oral sex among men who have sex with men and in the population of men who have sex with men

We examined HIV infection and estimated the population-attributable risk percentage (PAR%) for HIV associated fellatio among men who have sex with other men (MSM). Among 239 MSM who practised exclusively fellatio in the past 6 months, 50% had three partners, 98% unprotected; and 28% had an HIV-positive partner; no HIV was detected. PAR%, based on the number of fellatio partners, ranges from 0.10% for one partner to 0.31% for three partners. The risk of HIV attributable to fellatio is extremely low.     

Social cohesion,social participation and HIV testing among men who have sex with men in Swaziland

Social cohesion and social participation are social factors that may help reduce HIV risks and optimize health-seeking behaviors. We examined the association between these factors and HIV testing in the last 12 months among men who have sex with men (MSM) in Swaziland using a cross-sectional survey conducted with 326 men, 18 years of age or older reporting having sex with another man in the last 12 months. Social capital analyses included measures of social cohesion and social participation. The social cohesion measurement scale was created through exploratory factor analysis using polychoric correlations to determine unidimensionality and Cronbach's Alpha to assess internal consistency. The measurement scale was divided at the 25th and 75th percentiles using “high,” “medium” and “low” levels of social cohesion for between-group comparisons. The social participation index included four questions regarding participation, resulting in a participation index ranging from 0 to 4. In the final multivariate logistic regression model, an increase in the level of social participation was found to be significantly associated with HIV testing in the last 12 months, adjusting for age, income, reporting a casual partner, family exclusion and rejection by other MSM due to sexual orientation (adjusted odds ratio [aOR]: 1.3, 95% confidence interval [CI] 1.1–1.7, p?p?相似文献   

Heterogeneity of risk among African-American men who have sex with men

The objective of this study was to examine the social mixing and sexual risk taking of African-American men who have sex with men (AAMSM). The design was a cross-sectional survey with targeted, ethnographically informed recruitment of respondents (n = 95), and subsequent recruitment of their network partners (n = 63). We ascertained current demographics, occupation, peer norms for sexual activity, community involvement, and information about members of their social and sexual network. Risk level was categorized by the frequency of anal sex and the consistency of condom use for anal sex. Twenty-nine of 158 (18.4%) persons were classified as being at high risk (any anal intercourse in the past three months with less than 100% condom use); 79 of 158 (50%) were at medium risk (any anal intercourse in the past three months with 100% condom use reported), and 50 (31.7%) were at low risk (no reported anal intercourse). The risk groups were similar with regard to perception of behavioural and community norms. White-collar workers associated predominantly with each other and other groups mixing preferentially with white-collar workers. Clustering within contact networks (the extent to which partners to a respondent know each other) was high for all risk groups (approximately 0.4-0.5), indicating dense, interactive networks. In conclusion, this study group demonstrates a greater degree of social mixing and heterogeneity than is commonly assumed for AAMSM. At least some portion of AAMSM has internalized public health messages about safer sexual activity. Intervention programmes should avoid the pitfalls of assumed homogeneity.     

HIV testing and HIV knowledge among men who have sex with men in Natal,Northeast Brazil

Background

Men who have sex with men (MSM) account for the highest prevalence of HIV in Brazil. HIV testing allows to implement preventive measures, reduces transmission, morbidity, and mortality.

HIV testing among social media-using Peruvian men who have sex with men: correlates and social context

HIV remains concentrated among men who have sex with men (MSM) in Peru, and homophobia and AIDS-related stigmas have kept the epidemic difficult to address. Gay self-identity has been associated with increased HIV testing, though this relationship has not been examined extensively. Social media use has been rapidly increasing in Peru, yet little is known about MSM social media users in Peru. This study sought to investigate the demographic, behavioral, and stigma-related factors associated with HIV testing among social media-using Peruvian MSM. Five hundred and fifty-six MSM from Lima and surrounding areas were recruited from social networking websites to complete a survey on their sexual risk behaviors. We examined the demographic and social correlates of HIV testing behavior among this sample. Younger age and non-gay identity were significantly associated with lower likelihood of getting tested in univariate analysis. After controlling for key behaviors and AIDS-related stigma, younger age remained significantly associated with decreased testing. Participants who engaged in discussions online about HIV testing were more likely to get tested, while AIDS-related stigma presented a significant barrier to testing. Stigma severity also varied significantly by sexual identity. Youth appear to be significantly less likely than older individuals to test for HIV. Among Peruvian MSM, AIDS-related stigma remains a strong predictor of willingness to get tested. Social media-based intervention work targeting Peruvian youth should encourage discussion around HIV testing, and must also address AIDS-related stigma.     

Investigating partner abuse among HIV-positive men who have sex with men

High rates of partner abuse (PA) of all types—physical, sexual, and psychological—have been identified in studies of HIV-positive individuals. We examined both the prevalence and correlates of same-sex PA in HIV-positive men who have sex with men (MSM). Participants recruited from public outpatient HIV clinics (N = 168) completed CASI surveys about PA and current physical and mental health. Electronic medical record data were obtained for HIV biomarkers. Results indicate high rates of past year PA (physical, 19%; sexual, 17%; psychological, 51%; any, 54%), with rates comparable to, or higher than, those reported in recent studies of HIV-positive women and older studies of HIV-positive MSM. Overall, participants endorsing past year PA reported poorer mental but not physical health. Participants who endorsed past year physical PA, specifically, reported the largest number of mental health problems. HIV care providers should routinely assess PA, especially physical PA, in all MSM patients.     

The resurgence of syphilis among men who have sex with men

PURPOSE OF REVIEW: To identify recent progress and emerging problems in addressing syphilis among men who have sex with men. RECENT FINDINGS: A resurgence of syphilis has occurred among men who have sex with men in many developed countries. Infection has been associated with HIV coinfection, multiple partners, and recreational drug use. Unlike HIV, oral sex appears to be a common route of syphilis transmission. Many prevention approaches have shown, at best, modest success. Variable clinical presentation and potentially inconclusive lab tests make diagnosis confusing. SUMMARY: As the infection remains relatively rare, clinicians treating men who have sex with men should maintain a high index of suspicion for syphilis lesions, and should screen their sexually active patients for latent disease. Debates about syphilis control and treatment continue. The clinical manifestations, serologic responses, efficacy of treatment, and complications of syphilis have always been complicated. HIV coinfection adds to the confusion.
