This study investigated the relationship between HIV health optimism (HHO) (the belief that health will remain good after HIV infection due to treatment efficacy), HIV-positive community attachment (HCA), gay community attachment (GCA) and serostatus disclosure to casual sex partners by HIV-positive men who have sex with men (MSM). Cross-sectional questionnaire data were gathered from 97 HIV-positive MSM attending an HIV treatment clinic in Dublin, Ireland. Based on self-reported disclosure to casual partners, participants were classified according to their pattern of disclosure (consistent, inconsistent or non-disclosers). Multinomial logistic regression was used to assess HHO, HCA and GCA as predictors of participants' pattern of disclosure. Classification as a non-discloser (compared to a consistent discloser) was associated with higher HHO, less HCA and greater GCA. Classification as an inconsistent discloser (compared to a consistent discloser) was associated with higher GCA. The study provided novel quantitative evidence for associations between the constructs of interest. The results suggest that (1) HHO is associated with reduced disclosure, suggesting optimism may preclude individuals reaping the benefits of serostatus disclosure and (2) HCA and GCA represent competing attachments with conflicting effects on disclosure behaviour. Limitations and areas for future research are discussed.  相似文献

We examined the prevalence of sex with older male partner (SWOMP) and its association with condomless anal intercourse (CAI) with male partners and unrecognized HIV infection among young men who have sex with men (MSM) in Shanghai, China. The analytic sample included 243 MSM who were 18–45 years and HIV negative or of unknown HIV serostatus. Older male partner refers to male sex partner who was at least 10 years older than themselves. Overall, 99 (43.0%) and 50 (20.7%) reported having SWOMP in lifetime and in the last 3 months, respectively. Having any CAI with male partners in the last 3 months was independently associated with SWOMP and sex with stable male partners in the last 3 months. Unrecognized HIV infection was independently associated with being HSV-2 positive and having any CAI with male partners as well as SWOMP in last 3 months. Sex with stable male partner in the last 3 months was also marginally significantly associated with unrecognized infection (p?=?0.084). Older partner selection is common among young MSM in China. Prevention programs should incorporate education messages about the HIV risk associated with SWOMP. MSM should be informed that having condomless sex with stable partners may place them at HIV risk.  相似文献

We analysed HIV disclosure between Australian men who have sex with men (MSM) who reported anal intercourse with their last casual male partner. Of 804 MSM included in the analysis, 413 reported HIV disclosure and 391 reported no disclosure. After identifying bivariate associations with HIV disclosure, we developed three models of HIV disclosure (one for untested, one for HIV-negative and one for HIV-positive MSM). A range of factors was found to be associated with HIV disclosure. Having previously had sex with the last casual male partner and expecting HIV-negative and HIV-positive men to disclose before sex were predictors of HIV disclosure shared by more than one serostatus group. As unprotected anal intercourse was more common among MSM who disclosed (across all serostatus groups), we suggest caution should be exercised before encouraging HIV disclosure as a prevention strategy. Nondisclosure remains more strongly associated with safe sex among Australian MSM.  相似文献

Nigerian men who have sex with men (MSM) have a high burden of HIV infection and are known to engage in bisexual behavior. This study presents the first data on characteristics and correlates of Nigerian men having sex with men and women (MSMW) in three Nigerian cities. Five hundred and fifty-seven MSM who engaged in anal sex with men completed a behavioral survey; 48.1% of these MSM also engaged in sex with women in the previous 2 months. MSMW displayed high levels of risky sexual behavior with female sex partners; casual (56.0%) and multiple female partners were common (69.0%) and 66.0% had unprotected vaginal sex. As much as 45.1% MSMW had anal sex with female partners of which 74.0% did not use protection in the 2 months prior. In bivariate analyses, bisexual behavior was associated (p<0.05) with being married or living with a women (OR 5.0, 95% CI = 2.6–9.4), less education (OR 2.0, 95% CI = 1.4–3.0), bisexual/straight identity (OR 2.3, 95% CI = 1.6–3.2), being an insertive partner (OR 3.0, 95% CI = 1.9–4.5), being HIV-negative (OR 1.6, 95% CI = 1.1–2.5), living in Lagos (OR 2.3, 95% CI = 1.7–2.2), being Muslim (OR 1.7, 95% CI = 1.1–2.5), and being away from home (OR 1.5, 95% CI = 1.0–2.1). In the multivariate model, being married to or living with a woman (AOR = 5.1; 95% CI = 2.5–10.3), bisexual/straight identity (AOR = 2.2; 95% CIs = 1.5–3.3), being an insertive partner (AOR = 3.0; 95% CI = 1.9–4.9), being away from home (AOR = 1.6; 95% CI = 1.1–2.3) and living in Lagos (AOR = 1.7; 95% CI = 1.0–2.8) remained significant (p< 0.05). High levels of bisexual behavior exist among Nigerian MSM, and these men engage in risky sexual behaviors with both male and female sex partners. While decriminalization of same-sex behavior in Nigeria will promote access to HIV prevention programs, current MSM interventions must incorporate information on safe sex with both male and female sex partners.  相似文献

Emerging evidence has suggested that seropositive men who have sex with men (MSM) do not only face biased treatment from the general public but also from members of the MSM community. We conceptualized such biases perpetuated within the MSM community as human immunodeficiency virus (HIV) in-group stigma. This study examined the pathways by which perceived HIV in-group stigma impacted the mental health of seropositive MSM in Hong Kong. Internalized HIV stigma, serostatus disclosure concerns, and negative reactions towards HIV stigma were hypothesized as intermediate factors. Based on 100 Chinese seropositive MSM who were on antiretroviral therapy, results of a path analysis partially supported our hypotheses. Only negative reactions towards HIV stigma within the MSM community was a significant intermediate factor. The findings highlight the importance of understanding seropositive MSM’s different reactions to HIV stigma perpetuated within the MSM community. On top of stigma reduction research, further research may explore ways that help seropositive MSM cope with HIV in-group stigma and foster resilience.  相似文献

The objectives of this cross-sectional study were to compare sociodemographic and risk behavior characteristics between black men who have sex with both men and women (MSMW) and those who have sex with men only (MSMO) and assess factors associated with having any unprotected vaginal and/or anal intercourse (UVAI) with women in the last 3 months. Data from 326 black men who reported recent unprotected anal intercourse with a man in an HIV behavioral intervention study in New York City were analyzed. Baseline characteristics were compared between MSMW and MSMO, and factors associated with having any UVAI in the past 3 months with women among MSMW were evaluated. In total, 26.8% reported having sex with both men and women in the last 3 months. MSMW were less likely to be HIV infected, use amyl nitrates, and have unprotected receptive anal sex with most recent male partner. MSMW were more likely to be over 40 years old and use heroin. A total of 55.6% of MSMW reported having UVAI with women in the last 3 months. Compared to MSMW having only protected sex, MSMW having any UVAI with women were less likely to be HIV infected and to disclose having sex with men to female partners; they were more likely to have greater than four male sex partners in the last 3 months. In conclusion, HIV prevention interventions among black MSMW should directly address the risk of HIV transmission to both their female and male partners. Disclosure of bisexuality to female partners may be an important component of future prevention efforts.  相似文献

Nineteen semistructured interviews with HIV-positive methamphetamine-using gay, bisexual, or other MSM were analyzed qualitatively and using Critical Incident Measure (CIM). Among those who reported successful disclosure, themes regarding disclosure strategies and precontact disclosure emerged. Although few men spontaneously discussed the association between methamphetamine and disclosure, those who did reported less inclination to ascertain partner serostatus while under the influence. Men who reported disclosure to an HIV-seroconcordant partner were more likely to report not exchanging semen in this encounter compared with nondisclosers, whereas condom nonuse emerged as a theme across disclosure groups. Most of those who reported nondisclosure described their most recent encounter under the influence as occurring in the context of a public sex environment and/or with multiple partners. Understanding the interaction between methamphetamine use and serostatus disclosure practices, particularly among HIV-positive men, and how this interaction impacts sexual risk-taking has important implications for HIV prevention work.  相似文献

To increase understanding of the HIV epidemic among MSM in Barcelona, anonymous questionnaires were completed by 640 MSM recruited in the city in 2002. The prevalence of unprotected anal intercourse (UAI) with casual male partners in the prior 12 months was higher among self-reported HIV-positive men (confirmed through saliva testing) than among men who were HIV-negative or of unknown serostatus (35% vs. 20%, p < .01). The prevalence of UAI with steady male partners was substantially lower among HIV-positive men than other men (28% vs. 60%, p < .01). In multivariate analyses, UAI with casual partners was more likely among HIV-positive individuals; those who used drugs before sex; perceived less acceptance of their sexual orientation by family, friends, or coworkers; and were less concerned about HIV prevention because of antiretroviral therapy (ART). UAI with steady partners was more likely among HIV-negative men with seroconcordant partners, those living with a partner, and men less concerned about HIV prevention because of ART. Findings indicate a need for prevention programs targeting HIV-positive MSM in Barcelona. Attention to substance use and attitudes about HIV prevention are needed for MSM in general.  相似文献

The syphilis epidemic among men who have sex with men (MSM) in major US cities and concomitant increases in high-risk sexual behavior, have raised concerns of increased HIV transmission in this population. Therefore, to provide information for health promotion and disease awareness efforts, we investigated sexual behaviors, partner selection preferences and HIV serostatus disclosure practices of MSM at the White Party in Palm Springs, California. Circuit party attendees reported engaging in unprotected anal sex, however, a high proportion reported disclosing their HIV status. These findings suggest that some gay men are serosorting as a risk reduction strategy or implementing sexual risk reduction strategies to protect themselves and their partners. In our study, HIV-negative men were nine times more likely to report a preference for a seroconcordant sexual partner. The self-protecting attitudes of HIV-negative men in our sample outweighed the partner-protecting attitudes of HIV-positive men. This suggests that prevention interventions focusing on HIV-positive persons are warranted.  相似文献

This study investigated the associations between forms of HIV-related optimism, HIV-related stigma, and anxiety and depression among HIV-positive men who have sex with men (MSM) in the United Kingdom and Ireland. HIV health optimism (HHO) and HIV transmission optimism (HTO) were hypothesised to be protective factors for anxiety and depression, while the components of HIV-related stigma (enacted stigma, disclosure concerns, concern with public attitudes, and internalised stigma) were hypothesised to be risk factors. Data were collected from 278 HIV-positive MSM using an online questionnaire. The prevalence of psychological distress was high, with close to half (48.9%) of all participants reporting symptoms of anxiety, and more than half (57.9%) reporting symptoms of depression. Multiple linear regressions revealed that both anxiety and depression were positively predicted by internalised stigma and enacted stigma, and negatively predicted by HHO. For both anxiety and depression, internalised stigma was the strongest and most significant predictor. The results highlight the continued psychological burden associated with HIV infection among MSM, even as community support services are being defunded across the United Kingdom and Ireland. The results point to the need for clinicians and policy makers to implement stigma reduction interventions among this population.  相似文献

HIV serostatus disclosure before sex can facilitate serosorting, condom use and potentially decrease the risk of HIV acquisition. However, few studies have evaluated HIV serostatus disclosure from partners before sex. We examined the rate and correlates of receiving HIV serostatus disclosure from regular and casual male partners before sex among an online sample of men who have sex with men (MSM) in China. An online cross-sectional study was conducted among MSM in eight Chinese cities in July 2016. Participants completed questions covering sociodemographic information, sexual behaviors, HIV testing (including HIV self-testing) history, self-reported HIV status, and post-test violence. In addition, participants were asked whether they received HIV serostatus disclosure from their most recent partners before sex. Overall, 2105 men completed the survey. Among them, 85.9% were never married, and 35.4% had high school or less education. A minority (20.6%, 346/1678; 17.8%, 287/1608) of men received HIV serostatus disclosure from their most recent regular and casual male partners, respectively. Multivariate analysis indicated that participants who ever self-tested for HIV were more likely to have received HIV status disclosure from regular [adjusted OR (aOR) = 1.92, 95% CI 1.50–2.44] and casual (aOR = 2.34, 95% CI 1.80–3.04) male partners compared to never self-tested participants. Compared to participants who had not received HIV status disclosure from regular partners, participants who received disclosure from regular male partners had higher likelihood in experiencing post-test violence (aOR = 5.18, 95% CI 1.53–17.58). Similar results were also found for receiving HIV serostatus disclosure from casual partners. This study showed that HIV serostatus disclosure from partners was uncommon among Chinese MSM. Interventions and further implementation research to facilitate safe disclosure are urgently needed for MSM.  相似文献

Serosorting (i.e., engaging in unprotected sex with partners known to be of the same serostatus) can be a difficult process for men who have sex with men (MSM) who frequently make assumptions about their partners' serostatus. This process can be further complicated by a partner's dishonesty as well as other individual and contextual factors. The present study specifically examined how assumptions of serostatus made about unknown serostatus partners impact on the sexual behavior of 110 alcohol-abusing HIV-positive MSM. Although previous research has shown that HIV-positive MSM are more likely to serosort with other known HIV-positive men than with known HIV-negative men, our data suggest that unprotected sex behavior may not be specifically driven by whether or not they made assumptions of seroconcordance or serodiscordance. The types of assumptions these HIV-positive MSM made about their unknown status sexual partners and the basis for such assumptions were also examined. Owing to the ambiguities involved in assumptions of a partner's serostatus in sexual encounters, the 'unknown status' partner category is analytically distinct from 'known status' categories, and needs to be more fully explored because of its impact on perceived serosorting, rather than actual serosorting, among HIV-positive men.  相似文献

Barriers to HIV testing and HIV care and treatment pose significant challenges to HIV prevention among men who have sex with men (MSM) in China. We carried out a qualitative study to identify barriers and facilitators to HIV testing and treatment among Chinese MSM. In 2012, seven focus group (FG) discussions were conducted with 49 MSM participants in Nanjing, China. Purposive sampling was used to recruit a diverse group of MSM participants. Semi-structured interviews were conducted to collect FG data. Major barriers to testing included gay- and HIV-related stigma and discrimination, relationship type and partner characteristics, low perception of risk or threat, HIV is incurable or equals death, concerns of confidentiality, unaware that testing is offered for free, and name-based testing. Key facilitators of testing included engaging in high-risk sex, sense of responsibility for partner, collectivism, testing as a part of standard/routine medical care, MSM-friendly medical personnel, increased acceptance of gay/bisexual men by the general public, legal recognition and protection of homosexuals, and home self-testing. Barriers to treatment included negative coping, nondisclosure to families, misconceptions of domestically produced antiretroviral drugs (ARVs) and the benefits of treatment, and costs associated with long-term treatment. Facilitators of treatment included sense of hopefulness that a cure would be found, the cultural value of longevity, peer social support and professional psychological counseling, affordable and specialized treatment and care, and reduced HIV-related stigma and discrimination. Finally, for both testing and treatment, more educational and promotional activities within MSM communities and among the general public are needed.  相似文献

OBJECTIVES: To assess the prevalence of and factors associated with "Barebacking" as a sociocultural phenomenon in a sample of HIV-positive and -negative men who have sex with men (MSM), and to assess the reasons for barebacking and venues for meeting partners. DESIGN: A cross-sectional survey of MSM recruited in the San Francisco Bay Area from July 2000 to February 2001. METHODS: Barebacking, defined as "intentional anal sex without a condom with someone other than a primary partner", was assessed among men who had heard of the term. Participants were recruited outside multiple venues and interviewed later at community locations. Chi-square and multivariate logistic regression were used for analysis. RESULTS: The sample (n = 554) of MSM were African-American (28%), Latino (27%), white (31%) and other race/ethnicity (14%); 35% reported being HIV-positive. Seventy per cent of the men had heard of barebacking. Among men aware of the term, 14% had barebacked in the past 2 years (22% of HIV-positive versus 10% of HIV-negative men, P < 0.001); 10% of the full sample did so. The prevalence of barebacking did not differ by race/ethnicity or sexual orientation identification. Men tended to report bareback partners who had the same HIV serostatus; however, a sizeable proportion of men had partners of different or unknown serostatus. Increased physical stimulation and emotional connectedness were the primary reasons for barebacking. CONCLUSION: New approaches are needed to reduce bareback behavior and the risk of HIV transmission, including innovative health-promoting behavioral and biomedical interventions.  相似文献

Antiretroviral Therapy (ART) suppresses HIV replication, reducing the risk of transmission. However, many people living with HIV in the US are not virally suppressed even after diagnosis and initiating ART, and may become disengaged from care at each stage of the HIV care continuum (HCC). In the current study we assessed the sexual risk behaviors of MSM by HCC stage. US MSM who completed an online survey (N?=?12,995) in 2015 were categorized into 6 HCC groups. Mean age was 39.2 and a majority identified as White (49.6%). At every stage of the HCC, we found higher proportions of individuals engaged in care compared to CDC estimates. A majority of the sample was HIV-positive and engaged in care, with 67.2% of HIV-positive participants reporting viral suppression with ART. Across HCC groups, participants reported high rates of past 6-month condomless anal sex (CAS) (79.2%–84.8%) and CAS with serodiscordant or unknown status partners (38.0%–84.1%). Notably, MSM with unknown HIV serostatus reported the highest proportion of CAS and serodiscordant CAS. HIV-positive MSM not on ART were more likely to report an STI diagnosis (p?p?p?相似文献

This study assessed HIV-positive men's sexual behaviours with partners at risk for infection, and examined the extent to which safer sex was associated with interpersonal communication variables, namely, (1). disclosure of one's seropositive status and (2). specific communication with partners about safer-sex practices. A total of 105 HIV-positive men (43% homosexual, 38% bisexual, 19% heterosexual), randomly sampled at an HIV outpatient clinic in Los Angeles, completed a behavioural questionnaire assessing events in their most recent sexual encounter with an HIV-negative or unknown serostatus partner. Results indicated that men who disclosed their seropositive status and explicitly discussed the topic of safer sex with their at-risk partners had a significantly higher prevalence of protected anal or vaginal intercourse than did men who disclosed only. The findings suggest that post-test counselling regarding the importance of disclosing one's seropositive status to sex partners should be augmented by behavioural interventions that enhance seropositive persons' skills in communicating explicitly with partners about safer sex to help reduce transmission of HIV.  相似文献

Three quarters of new HIV infections in the US are among men who have sex with men (MSM). In other populations, incarceration is a social determinant of elevations in viral load and HIV-related substance use and sex risk behavior. There has been limited research on incarceration and these HIV transmission risk determinants in HIV-positive MSM. We used the Veterans Aging Cohort Study (VACS) 2011-2012 follow-up survey to measure associations between past year and prior (more than one year ago) incarceration and HIV viral load and substance use and sex risk behavior among HIV-positive MSM (N?=?532). Approximately 40% had ever been incarcerated, including 9% in the past year. In analyses adjusting for sociodemographic factors, past year and prior incarceration were strongly associated with detectable viral load (HIV-1 RNA >500 copies/mL) (past year adjusted odds ratio (AOR): 3.50 95% confidence interval (CI): 1.59, 7.71; prior AOR: 2.48 95% CI: 1.44, 4.29) and past 12 month injection drug use (AORs?>?6), multiple sex partnerships (AORs?>?1.8), and condomless sex in the context of substance use (AORs?>?3). Past year incarceration also was strongly associated with alcohol and non-injection drug use (AOR > 2.5). Less than one in five HIV-positive MSM recently released from incarceration took advantage of a jail/prison re-entry health care program available to veterans. We need to reach HIV-positive MSM leaving jails and prisons to improve linkage to care and clinical outcomes and reduce transmission risk upon release.  相似文献

HIV sexual transmission risk behaviors were examined among 1,065 Latino and 1,140 black men who have sex with men (MSM). Participants completed a computer-administered questionnaire and were tested for HIV infection. Of men who reported that their last HIV test was negative or that they had never been tested or did not get the result of their last test, 17% of black and 5% of Latino MSM tested HIV-positive in our study. In both ethnic groups, the three-month prevalence of unprotected anal intercourse (UAI) with HIV-negative or unknown serostatus partners was twice as high among men unaware of their HIV infection than men who knew they were HIV seropositive at the time of enrollment. UAI exclusively with HIV-positive partners was more prevalent among HIV-positive/aware than HIV-positive/unaware men. The findings advance understanding of the high incidence of HIV infection among black MSM in the U.S.  相似文献
