In India, men who have sex with men (MSM) remain hidden because anal intercourse was criminalized and marriage socially required.
We characterize HIV/STI prevalence among MSM in Tamil Nadu. Eligible participants were recruited using respondent-driven sampling
in eight cities (n = 721). Median age was 28, 34% were married and 40% self-identified as homosexual. Median number of male partners in the
prior year was 15; 45% reported any unprotected anal intercourse (UAI). HIV, herpes simplex virus-2 (HSV-2), chronic hepatitis B virus (HBV) and syphilis prevalence were 9, 26, 2 and 8%, respectively; among married men, all
were higher: 14, 32, 3 and 11% (p < 0.01 for HIV and HSV-2). Less education, HSV-2, more male partners, UAI and not having a main male partner were associated
with HIV prevalence. The high STI and UAI prevalence may lead to a burgeoning HIV epidemic among MSM, reinforcing the need
for focused preventive measures incorporating complex circumstances. 相似文献

Accumulating evidence supports couple-based approaches for HIV/STI preventive interventions. Yet, to date, no studies have
examined couple-based sexual risk reductions intervention specifically for men who have sex with men (MSM) from populations
with elevated rates of HIV/STI transmission, such as black MSM and methamphetamine-involved MSM. We pilot tested—using a pre-/post-test
design—a seven-session couple-based intervention for black, methamphetamine-using, black MSM couples engaging in sexual risk.
Feasibility was assessed via recruitment and retention rates; potential efficacy relied on self-reported sexual risk and drug
use prior to and two months following intervention delivery. We enrolled 34 couples (N = 68 men). Over 80% attended all seven intervention sessions, and retention exceeded 95% at two-month follow-up. At follow-up,
participants reported significantly fewer sexual partners, fewer episodes of unprotected anal sex, and greater condom use
with their main partner; participants also reported significantly less methamphetamine use, any illicit drug use, and number
of illicit drugs used. These findings indicate that couple-based HIV/STI intervention is feasible and promising for at-risk
black MSM couples. 相似文献

ABSTRACTWe conducted a randomized control trial to evaluate the impact of a novel technology-based intervention on HIV risks and condom use behaviors among Thai men who have sex with men (MSM). Between April 2016 and August 2017, participants aged 18 years and above, and having engaged in unprotected sex in past six months were randomly assigned to control and intervention arm, and received HIV testing at baseline, month 6 and 12. Intervention arm participants engaged in 12-monthly HIV/STI prevention educational sessions delivered via Vialogues.com. Of 76 MSM enrolled, 37 were randomized to intervention and 39 to control arm. Median age was 28 (IQR 24–32) years. Thirty-three (89.2%) intervention arm participants completed all 12-monthly Vialogues sessions. At month 12, intervention arm had higher retention rate (p?=?0.029) and higher median percentage of condom use for anal intercourse (p?=?0.023) versus control arm. Over the 12-month period, intervention arm reported significant reduction in self-perceived HIV risk (p?=?0.001), popper usage (p?=?0.002), median number of sexual partners (p?=?0.003), and increased median condom use percentage (p?=?0.006). Our study highlights that “Vialogues” intervention significantly reduced number of sexual partners and condomless anal intercourse rates among Thai MSM, and has positive implications for reducing epidemic among key populations. 相似文献

We assessed trends in behavioral risk for HIV infection among men who have sex with men (MSM). Seattle MSM participated in
random digit dial telephone surveys in 2003 (n = 400) and 2006 (n = 400). Fourteen percent in 2003 and 9% in 2006 reported unprotected anal intercourse with a partner of different or unknown
HIV status (non-concordant UAI; odds ratio [OR] = 0.7; 95% confidence interval [CI]: 0.5, 1.2). Compared to participants in
2003, participants in 2006 met a greater proportion of their anal sex partners through the Internet (OR = 2.0; 95% CI: 1.2,
3.1). Although the proportion of anal sex partnerships formed online increased between 2003 and 2006, Internet partnerships
were not more risky than those initiated elsewhere. While the emergence of the Internet as a venue through which men meet
partners demonstrates that sexual risk among MSM remains highly dynamic, our findings suggest that sexual risk behavior among
MSM is currently stable. 相似文献

We examined racial/ethnic differences in reported seroadaptive and serodisclosure behaviors among the partnerships of MSM
recruited for a cross-sectional survey using time-location sampling (TLS) in San Francisco during 2007–2008. The sample (N = 1,199) consisted of 12.2% Asian/Pacific Islander (API), 52.4% White, 6.8% Black, 20.2% Latino, and 8.5% of “other” race/ethnicity.
Pure serosorting was most common (about 20%) among HIV-negative men while seropositioning was most used (about 15%) by HIV-positive
men. Reported seroadaptive behaviors did not differ significantly across races/ethnicities among both HIV-negative and HIV-positive
men. However, HIV-positive Black and Latino men were significantly more likely to report no preventive, seroadaptive behavioral
strategy (i.e., unprotected insertive anal intercourse with unknown status or serodiscordant partners). Among men who reported
engaging in seroadaptive behaviors, they reported not discussing HIV status with a third of their partners—a major concern
in that lack of disclosure undermines the effectiveness and means to practice serosorting. Partnerships of API and Black men
were least likely to involve serodisclosure behaviors. Our study confirms that seroadaptive behaviors are common preventive
strategies reported by MSM of all races/ethnicities, and does not find strong evidence that racial/ethnic differences in seroadaptive
behaviors are enhancing disparities in HIV prevalence. The implications are that condom promotion and safe sex messages are
not the only prevention measures adopted by MSM and that public health professionals should be well aware of current trends
within the MSM community in order to better assist HIV prevention efforts. 相似文献

High rates of depression have been observed among men who have sex with men (MSM) relative to the general adult male population;
however, a dearth of research has explored depression among Black MSM. Black MSM (n = 197) recruited via modified respondent-driven sampling between January and July 2008 completed an interviewer-administered
quantitative assessment and voluntary HIV counseling and testing. Bivariate and multivariable logistic regression procedures
examined the associations of demographics, behavioral HIV risk factors, and psychosocial variables with depressive symptoms
by severity, using the 20-item Center for Epidemiologic Studies Depression Scale (CES-D). Adjusting for demographic and behavioral
variables, significant factors associated with (1) clinically significant depressive symptoms (33%; CES-D score ≥ 16): being
publicly insured by Medicaid, having serodiscordant anal sex with a casual male partner, and being diagnosed with an STD in
the prior 12 months; (2) moderate depressive symptoms (19%; CES-D score 16–26): having serodiscordant unprotected anal sex
with a casual male partner and being diagnosed with an STD in the prior 12 months; (3) severe depressive symptoms (14%; CES-D
score 27+): being publicly insured by Medicaid and reporting difficulty accessing healthcare in the past 12 months. Moderately
depressed Black MSM may be more likely to engage in behaviors that place them at increased risk for HIV and other STDs. HIV
prevention interventions for Black MSM may benefit from incorporating screening and/or treatment for depression, allowing
MSM who are depressed to respond more effectively to behavioral change approaches. 相似文献

To estimate the prevalence of HIV and syphilis and to assess the predictors of unprotected anal intercourse (UAI) among men who have sex with men (MSM) in Beijing, a community-based survey recruited MSM in 2005 through internet advertisement, community outreach, and peer referral. Demographic, sexual, and HIV risk behavioral information were collected. Serospecimens were tested for HIV and syphilis infections. Of the 526 participants, 3.2% were HIV-positive, 11.2% syphilis-positive, 50% and 43.3% had UAI with regular and casual sex partners, respectively. Participants practicing UAI with regular male partners were independently associated with lower monthly income (adjusted odds ratio-AOR, 1.7; 95% CI, 1.0-3.0) and encountering male sex partners at bathhouses, public washrooms, and parks (AOR, 2.2; 95% CI, 1.0-4.9). Participants practicing UAI with casual male partners were associated with encountering male sex partners at bathhouses, publics washrooms, and park (AOR, 3.0; 95% CI, 1.8-5.2) and more male sex partners having receptive anal intercourse (AOR, 1.8; 95% CI, 1.1-2.9), and was inversely associated with receiving money for sex with men (AOR, 0.3; 95% CI, 0.2-0.7). Professional male sex workers were less likely to practice UAI in Beijing, suggesting the benefits of educational outreach to date. Further education, condom promotion, and prevention of sexually transmitted infections should be intensified urgently to combat the rising HIV epidemic among MSM in Beijing. 相似文献

This report presents data on participation in online or offline prevention activities among a sample of New York City men
who have sex with men (MSM) recruited online between April–August of 2007 who use the Internet to meet sex partners. The analysis
focuses on the 1,124 men who reported sex with a main or casual partner in the past 12 months. Over half (53%) of the MSM
reported unprotected anal intercourse (UAI) in the past year. Data from our multivariate analysis indicate that MSM who participate
in online or offline prevention activities were less likely to engage in UAI. 相似文献

We examined socio-demographic and behavioral characteristics of men who have sex with men (MSM) residing in Asia and correlates of unprotected receptive intercourse with Internet ejaculation (URAIE). Asia Internet MSM Sex Survey, a behavioral survey of MSM in Asia was conducted from 1 January to 28 February 2010. Data analysis was limited to participants aged 18 or above, biological male, and had one regular or casual sex partner in the past 6 months (n?=?10,413). Pearson's Chi-square test, t test and logistic regression were used to examine the correlates of URAIE in the past 6 months, the highest risk sexual behavior sampled. Of 7311 participants who had receptive anal intercourse, 47.5?% had URAIE, which was associated with the following attributes: less than high-school education and pre-college education compared to university (AOR?=?1.53, 95?% CI: 1.28, 1.83; AOR?=?1.22, CI: 1.08, 1.37), being in the heterosexual marriage (AOR?=?1.35, CI: 1.18, 1.56), having regular partners or both regular and casual partners compared to having casual partners (AOR?=?2.85, CI: 2.48, 3.27; AOR?=?2.32, CI: 2.06, 2.62), HIV-positive compared to HIV-negative status (AOR?=?1.39, 95?% CI: 1.08, 1.81), higher perception of HIV risk (AOR?=?1.62, CI: 1.34, 1.95), use of recreational drug before sex (AOR?=?1.30, CI: 1.14, 1.49), and use of the Internet as the main way to seek sex partners (AOR?=?1.21, CI: 1.08, 1.36). MSM from certain Asian countries reported alarming rates of URAIE. The internet can be used as a platform for HIV surveillance and intervention. 相似文献

A significant minority of Australian men who have sex with men (MSM) have never been tested for HIV and many men do not test
as often as recommended. Using data from 1770 HIV-negative and untested MSM collected in a national, online survey, we compared
men who had never tested for HIV with those who had tested over 12 months ago and men who had tested over 12 months ago with
those that had tested in the past year. Two multivariate logistic regression models were constructed. Compared with men tested
over 12 months ago, untested men were younger, less educated, less likely to have unprotected anal intercourse with a regular
male partner, less likely to have sought advice from a doctor, nurse or community organisation, more likely to expect HIV-negative
disclosure, had fewer gay friends and spent more time using social networking websites. Compared with men who had tested over
12 months ago, men who had tested within the last year were younger, more likely to expect HIV-negative disclosure and disclose
to casual partners, more likely to have sought advice from a doctor or nurse, had attended gay pools, gyms or beaches and
had more gay friends and more male sex partners. Our findings suggest that the Internet and sex education in schools are important
ways to promote HIV testing to untested MSM. Testing reinforcement messages delivered through gay community outreach and primary
care will reach previously tested MSM. 相似文献

Positive choices (PC), a brief sexual risk reduction intervention conducted with newly HIV-diagnosed men who have sex with men (MSM), was evaluated for preliminary efficacy. Participants were enrolled if they reported unprotected anal intercourse (UAI) in the three months prior to HIV diagnosis (n = 102). Three months after diagnosis, participants completed baseline assessments and were randomly assigned to receive the 3-session PC intervention or the comprehensive standard of care (C-SoC) at a community health center. Participants completed assessments at 3- (post intervention), 6-, and 9- months after baseline. Compared to C-SoC participants, PC participants significantly reduced the frequency of UAI with HIV serodiscordant (HIV negative or status unknown) partners over the 9-month follow-up period. No differences by condition were found in the frequency of UAI with all partners. The findings from this trial suggest that brief risk reduction approaches for newly-diagnosed MSM integrated into HIV care can benefit secondary HIV prevention efforts. 相似文献

In China, the HIV prevalence among men who have sex with men (MSM) has been increasing sharply. A total of 195 Hong Kong MSM having had sex with men in Shenzhen, a mainland China city separated from Hong Kong by a border, were recruited from some randomly selected gay venues in Shenzhen. Participants were face-to-face and anonymously interviewed. The results showed that in the last six months, respectively 62.1, 84.6, and 31.3 % of the participants from Hong Kong had had sex with commercial sex partners (CSP), non-regular partners (NRP) and regular partners (RP) in Shenzhen. The prevalence of unprotected anal intercourse (UAI) with these three types of sex partners was respectively 29.8, 27.9, and 78.7 %. Factors associated with UAI with any MSM in Shenzhen in the last six months included perceived chances of contracting HIV, perceived non-availability of condoms, giving money/gifts to Shenzhen MSM sex partners, and perception that MSM partners in Shenzhen would not always insist on condom use (multivariate OR = 2.9–13.90, p < 0.05), whilst factors of inverse associations included university education, having had sex with NRP but not with CSP and RP in Shenzhen and self-efficacy of insisting on condom use (multivariate OR = 0.04–0.22, p < 0.05). In sum, the prevalence of having multiple types of male sex partners and UAI was high. This was especially true when anal sex with RP was involved. Cross-border HIV prevention is greatly warranted. It should ensure condom availability and modify perceptions toward UAI. 相似文献

Croatia has a low-level HIV epidemic and, as in a number of other Central and Southeastern European countries, sex between
men accounts for most HIV infections. This study examines sexual behavior and the correlates of condom use in a snowball sample
of 342 HIV non-infected men who have sex with men (MSM) in Zagreb. The median age of participants in the sample was 27 years.
The majority of participants (81%) reported using condom at last anal sex with casual partner and 56% claimed to have used
condoms consistently at anal sex with casual partners in the last 12 months. HIV risk self-assessment and number of sexual
partners were significantly correlated with condom use at last anal sex with casual partner. Self-assessed HIV-risk and heterosexual
activity were found associated with consistent condom use at anal sex with casual partners. To sustain a low-level HIV epidemic,
targeted intervention among young MSM is needed in Croatia. 相似文献

To examine the correlates for syphilis and the prevalence for HIV, hepatitis B, hepatitis C among men-who-have-sex-with-men
(MSM) in Beijing, China. A total of 541 MSM was recruited using peer-referral, community outreach, and Internet. Questionnaire-based
interviews provided information including, demographics, sexual and other risk behaviors. HIV prevalence was 4.8%, syphilis
19.8%, HCV 0.4% and HBsAg 6.5%. The median number of lifetime male sex partners was ten. In the past 3 months, 20.7% drank
alcohol ≥1 times per week. In the past month, 21.3 and 14.6% had unprotected anal intercourse with regular and casual male
sex partners, respectively. Syphilis infection was associated with less education, alcohol use, finding male sex partners
through bathhouses/public washrooms/parks, and diagnoses of sexual transmitted diseases (STDs). Syphilis is now epidemic among
Beijing’s MSM. Prevention efforts are urgent as HIV prevalence is already near 5%. Education, condom promotion, STD control,
and alcohol-related intervention are needed urgently. 相似文献

Data from 635 very poor men who have sex with men (MSM) were used to identify seroadaptation with 1,102 male partners reported between 2005 and 2007 in Los Angeles as part of the Sexual Acquisition and Transmission of HIV Cooperative Agreement Program. The mean age of the sample was 41.7 years; 53 % had experienced homelessness in the past year. Condoms were reported in 51 % of sexual events involving anal intercourse. HIV seroconcordance was reported in 41 % of sexual partnerships among HIV-positive participants. HIV-positive men were more likely to have oral-only or unprotected receptive anal intercourse and less likely to have unprotected insertive anal intercourse with HIV-negative or unknown partners compared to HIV-positive partners. Even in the face of poverty, HIV-positive MSM report mitigating risks of HIV-transmission though seroadaptation in the context of modest rates of condom use. 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

Many men who have sex with men (MSM) are among those who increasingly use the internet to find sexual partners. Few studies
have compared behavior by race/ethnicity in internet-based samples of MSM. We examined the association of race/ethnicity with
HIV risk-related behavior among 10,979 Hispanic, black, and white MSM recruited online. Significant variations by race/ethnicity
were found in: age, income level, sexual orientation, number of lifetime male and female sexual partners, and rates of unprotected
anal intercourse (UAI). Black and Hispanic men were more likely to report anal intercourse during the last sexual encounter,
but white men were more likely to report UAI. In multivariate analysis, UAI was associated with HIV infection and sex with
a main partner. Significant risk behavior variations by race/ethnicity were found. Research is needed to better target online
interventions to MSM who engage in UAI or have other risk factors for transmitting or acquiring HIV. 相似文献

POWER is a theory-based, on-line HIV prevention intervention developed specifically for Black men who have sex with men and women (BMSMW), an understudied group significantly impacted by HIV. To test its efficacy, we recruited 224 BMSMW using chain referral methods and randomly assigned 108 to POWER and 103 to a health information comparison condition. Three months after the intervention, participants assigned to POWER had lower odds of reporting any condomless vaginal or condomless anal intercourse (CVAI) compared to those in the comparison group (aOR = 0.49; 95 % CI 0.25–0.98; p = 0.044). The intervention was associated with significantly lower odds of condomless anal intercourse with male partners (aOR = 0.55; 95 % CI 0.34–0.91; p = 0.020) but not with female partners and serodiscordant sex with male partners but not with female partners. Future studies are needed to replicate these findings in larger and more diverse samples of BMSMW and to understand the underlying mechanisms through which intervention efficacy was achieved. 相似文献

Group sex is relatively common among gay men, and is a likely risk factor for infection with HIV and other sexually transmissible
infections (STI). The 5,432 participants in the 2008 Gay Community Periodic Survey in Sydney, Melbourne and Brisbane, Australia,
were asked about their participation in group sex. Nearly half (44.0%) of those who reported sex with casual male partners
in the previous 6 months also reported engaging in group sex. Among other factors, using drugs odds ratios (OR) and confidence
intervals (CI) (OR = 1.89, CI = 1.61–2.21), being HIV-positive (OR = 1.62, CI = 1.13–2.32), and engaging in anal intercourse,
both with a condom (OR = 3.03, CI = 2.46–3.73) and without a condom (OR = 5.68, CI = 4.53–7.12) were independently associated
with having engaged in group sex. This study suggests that gay men who engage in group sex represent an important priority
for targeted HIV and STI prevention activities and research. 相似文献

To assess the potential for HIV acquisition among men who have sex with men (MSM) in Guangzhou, China, we conducted a cross-sectional, anonymous, face-to-face survey of MSM in the metropolitan area of Guangzhou, China. As a pilot recruitment for a cohort study, participants were recruited by convenience sampling through newspaper and television advertising, website information, and respondent referral. Blood samples were tested for HIV, hepatitis B (HBV), hepatitis C (HCV), and syphilis. Client-centered HIV and STD counseling was provided.A total of 201 MSM were interviewed and 200 blood samples were tested. The prevalence of HIV antibody was 0% (97.5% CI 0–1.8%); 17.5% of MSM were HBV surface antigen positive; 1.0% had HCV antibodies; 10.5% had antibodies to syphilis. Syphilis seropositivity was associated with sex with a foreign MSM in the last six months and 10.4% reported sex with a foreign MSM overall. The majority (54.7%) reported unprotected anal sex with other men. Nearly one-third (31.8%) had regular female partners; 25.9% were currently married to a woman; 6% had casual female partners; 4.5% had sex with a female sex worker; 4.5% had sex with a male sex worker; and 12.9% had unprotected vaginal sex and unprotected anal sex with a man in the past six months. Only one MSM reported injection drug use (0.5%). The currently low prevalence of HIV but high level of unprotected anal sex, high prevalence of syphilis infection, and sexual networks that include foreign MSM point to a transient window for HIV prevention among MSM in Guangzhou. We recognize challenges to recruiting a representative sample of MSM and retaining them in longitudinal cohort studies. 相似文献
