The association between HIV treatment optimism--beliefs about susceptibility to transmit HIV, motivation to use condoms, and severity of HIV--and sexual risk behavior was examined among HIV-positive African American men who have sex with men (MSM). Participants were 174 men recruited in four major metropolitan areas of the United States to participate in a weekend HIV risk reduction intervention. Baseline results revealed that beliefs in less susceptibility to transmit HIV and less motivation to use condoms were significantly associated with more unprotected anal intercourse among serodiscordant casual partners. Less motivation to use condoms also predicted more unprotected insertive and receptive anal sex and was more important than susceptibility beliefs in predicting these behaviors. Suggestions are offered of ways to better inform HIV-positive African American MSM about their misperceptions about HIV treatment and how their level of optimism about HIV treatment may diminish or encourage condom use. 相似文献

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. 相似文献

ABSTRACTMobile health (M-Health) has become a novel method for HIV prevention and the effects need to be promoted. The study purpose was to exam how a smartphone application (app) reduces HIV risky behaviour in men who have sex with men (MSM). The Safe Behaviour and Screening (SBS) app was developed, and included five features: record, output, and resources connection; information provision; testing services; interaction; and online statistics. A random assignment was used. The experimental group used the SBS app for six months. The control group did not use any intervention. There were 130 participants in the experimental group, and 135 in the control group. The average age of all subjects was 27.38 (SD?=?5.56). Compared to the control group, the experimental group had significantly higher mean score of safe behaviour knowledge, motivation, and skills; percentage of condom use during anal intercourse; frequency of searching for testing resources and getting HIV and syphilis tests. The frequency of anal intercourse and recreational drug usage were significantly lower in the experimental group. The SBS app could decrease the HIV risky behaviour among MSM and be applied to HIV prevention and nursing intervention. 相似文献

Rural South African men who have sex with men (MSM) are likely to be underserved in terms of access to relevant healthcare and HIV prevention services. While research in urban and peri-urban MSM populations has identified a range of factors affecting HIV risk in South African MSM, very little research is available that examines HIV risk and prevention in rural MSM populations. This exploratory study begins to address this lack by assessing perceptions of HIV risk among MSM in rural Limpopo province. Using thematic analysis of interview and discussion data, two overarching global themes that encapsulated participants’ understandings of HIV risk and the HIV risk environment in their communities were developed. In the first theme, “community experience and the rural social environment”, factors affecting HIV risk within the broad risk environment were discussed. These included perceptions of traditional value systems and communities as homophobic; jealousy and competition between MSM; and the role of social media as a means of meeting other MSM. The second global theme, “HIV/AIDS knowledge, risk and experience”, focused on factors more immediately affecting HIV transmission risk. These included: high levels of knowledge of heterosexual HIV risk, but limited knowledge of MSM-specific risk; inconsistent condom and lubricant use; difficulties in negotiating condom and lubricant use due to uneven power dynamics in relationships; competition for sexual partners; multiple concurrent sexual partnerships; and transactional sex. These exploratory results suggest that rural South African MSM, like their urban and peri-urban counterparts, are at high risk of contracting HIV, and that there is a need for more in-depth research into the interactions between the rural context and the specific HIV risk knowledge and behaviours that affect HIV risk in this population. 相似文献

Limited health care access and missed opportunities for HIV and other sexually transmitted infection (STI) education and testing in health care settings may contribute to risk of HIV infection. In 2008, we conducted a case-control study of African American men who have sex with men (MSM) in a southeastern city (Jackson, Mississippi) with an increase in numbers of newly reported HIV cases. Our aims were to evaluate associations between health care and HIV infection and to identify missed opportunities for HIV/STI testing. We queried 40 potential HIV-infected cases and 936 potential HIV-uninfected controls for participation in this study. Study enrollees included HIV-infected cases (n=30) and HIV-uninfected controls (n=95) who consented to participate and responded to a self-administered computerized survey about sexual risk behaviors and health care utilization. We used bivariate analysis and logistic regression to test for associations between potential risk factors and HIV infection. Cases were more likely than controls to lack health insurance (odds ratio [OR]=2.5; 95% confidence interval [CI]=1.1-5.7), lack a primary care provider (OR=6.3; CI=2.3-16.8), and to not have received advice about HIV or STI testing or prevention (OR=5.4; CI=1.3-21.5) or disclose their sexual identity (OR=7.0; CI=1.6-29.2) to a health care provider. In multivariate analysis, lacking a primary health care provider (adjusted odds ratio [AOR]=4.5; CI=1.4-14.7) and not disclosing sexual identity to a health care provider (AOR=8.6; CI=1.8-40.0) were independent risk factors for HIV infection among African American MSM. HIV prevention interventions for African American MSM should address access to primary health care providers for HIV/STI prevention and testing services and the need for increased discussions about sexual health, sexual identity, and sexual behaviors between providers and patients in an effort to reduce HIV incidence and HIV-related health disparities. 相似文献

Previous research has indicated a high prevalence of childhood sexual abuse (CSA) among men who have sex with men (MSM) in the United States, and has suggested that CSA history is a risk factor for HIV infection in MSM. We conducted a systematic review to identify, synthesize, meta-analyze, and critique the current state of relevant literature. Systematic review methodology was utilized to identify 12 studies that compared MSM with a history of CSA to MSM without a history of CSA on HIV risk indicators including HIV serostatus, sexually transmitted infections (STIs), sexual behaviors, and illicit drug use. Overall, 27.3% (n = 4,263) of the MSM in all included studies (n = 15,622) reported a CSA history. Across the studies that used probabilistic sampling (n = 8,240), the estimated prevalence of CSA was 21.8% (n = 1,800). Meta-analysis indicated that MSM with CSA history were more likely to be HIV positive [odds ratio (OR) = 1.54; 95% confidence interval (CI) = 1.22-1.95)] and to engage in recent unprotected anal intercourse (OR = 1.85, 95% CI = 1.36-2.51). Studies also indicated that MSM with a history of CSA were more likely to report frequent casual male partners, substance use, and sex while under the influence of alcohol or other drugs. Trends across studies indicated a need for interventions to assess CSA history and address effects of CSA on sexual risk behavior of MSM. Inconsistencies across studies indicated a need to reach consensus among researchers and providers in defining CSA. 相似文献

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. 相似文献

OBJECTIVE: To evaluate the effectiveness and cost-effectiveness of a health department-based peer referral program for identifying previously undiagnosed cases of HIV among men who have sex with men (MSM). DESIGN AND METHODS: Between 2002 and 2005, 283 MSM peer recruiters were enrolled in a public health program in King County, Washington, USA. Peer recruiters were enrolled from a sexually transmitted disease (STD) clinic, an HIV clinic, via media advertisements and through collaboration with community-based organizations (CBO). The peer recruiters underwent a brief training and were then paid US$ 20 for each peer they referred to be tested for HIV, STD and viral hepatitis. Peers were paid US$ 20 for being tested. The main outcome measure was the number of new cases of HIV identified and cost per case of HIV identified. RESULTS: Recruiters referred 498 peers for HIV, STD and hepatitis testing. Among 438 peers not previously diagnosed with HIV, 22 (5%) were HIV positive, of whom 18 received their HIV test results. Other infections were variably prevalent among tested peers: gonorrhea [23/307 (8%)], chlamydia [6/285 (2%)], syphilis [1/445 (0.2%)], hepatitis C [61/198 (31%)], surface antigen positive hepatitis B [8/314 (3%)]. Excluding the costs of testing for viral hepatitis and STDs other than HIV, the cost per new HIV case identified was US$ 4929. During the same period, the cost per new case of HIV detected through bathhouse-based HIV testing and through the county's largest CBO-based HIV testing program were US$ 8250 and US$ 11 481, respectively. CONCLUSIONS: Peer referral is an effective means of identifying new cases of HIV among MSM. 相似文献

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. 相似文献

OBJECTIVES: Risk factors for HIV acquisition were examined in a recent cohort of men who have sex with men (MSM). DESIGN: A longitudinal analysis of 4295 HIV-negative MSM enrolled in a randomized behavioral intervention trial conducted in six US cities. METHODS: MSM were enrolled and assessed for HIV infection and risk behaviors semi-annually, up to 48 months. RESULTS: In multivariate analysis, men reporting four or more male sex partners, unprotected receptive anal intercourse with any HIV serostatus partners and unprotected insertive anal intercourse with HIV-positive partners were at increased risk of HIV infection, as were those reporting amphetamine or heavy alcohol use and alcohol or drug use before sex. Some depression symptoms and occurrence of gonorrhea also were independently associated with HIV infection. The attributable fractions of high number of male partners, use of alcohol or drugs before sex, and unprotected receptive anal intercourse with unknown status partners and the same with presumed negative partners accounted for 32.3, 29.0, 28.4 and 21.6% of infections, respectively. CONCLUSIONS: The challenge is to develop strategies to identify men in need. Interventions are needed to help men reduce their number of sexual partners, occurrences of unprotected anal intercourse, alcohol or drug use before sex and address other mental health issues. 相似文献

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?.01). MSM with high social cohesion had almost twice the odds of HIV testing in the last 12 months (aOR: 1.8, 95% CI 1.1–3.3, p?.05) as MSM with medium social cohesion, though the overall social cohesion variable was not found to be significant using a Wald test in either the adjusted or unadjusted logistic regression models. These data suggest that building solidarity and trust within and between groups may be a strategy to improve uptake of HIV testing. 相似文献

Epidemics of HIV in men who have sex with men (MSM) continue to expand in most countries. We sought to understand the epidemiological drivers of the global epidemic in MSM and why it continues unabated. We did a comprehensive review of available data for HIV prevalence, incidence, risk factors, and the molecular epidemiology of HIV in MSM from 2007 to 2011, and modelled the dynamics of HIV transmission with an agent-based simulation. Our findings show that the high probability of transmission per act through receptive anal intercourse has a central role in explaining the disproportionate disease burden in MSM. HIV can be transmitted through large MSM networks at great speed. Molecular epidemiological data show substantial clustering of HIV infections in MSM networks, and higher rates of dual-variant and multiple-variant HIV infection in MSM than in heterosexual people in the same populations. Prevention strategies that lower biological transmission and acquisition risks, such as approaches based on antiretrovirals, offer promise for controlling the expanding epidemic in MSM, but their potential effectiveness is limited by structural factors that contribute to low health-seeking behaviours in populations of MSM in many parts of the world. 相似文献

Among 976 men who have sex with men (MSM) who had undergone repeat HIV testing between 1984 and 2003 at a sexually transmitted infection clinic in Rome, Italy, we observed a dramatic increase in HIV incidence in 2002 and 2003, with the cumulative incidence for 2000-2003 being twice as high as that for 1984-1995, and significantly higher than that for 1996-1999. This trend suggests the need for interventions aimed at encouraging behavioural changes among MSM. 相似文献
