Men who have sex with men (MSM) are disproportionally affected by HIV. Although some theoretical models created to explain why individuals engage in risky sexual behavior contain an affective component, there has been relatively little focus on the influence of affect on sexual risk-taking. The goal of this study is to investigate the association between affect and condom use among MSM using an archival dataset from a survey of users of a popular sex-oriented website. Multilevel modeling was used to analyze daily diary data from 2871 MSM. At the within-person level, positive affect was positively related to condomless anal sex (CAS), whereas negative affect was negatively related to CAS. However, these results were qualified by interactions of trait affect and relationship to sex partner. These findings suggest that interventions focused on emotional regulation may have the potential to reduce CAS among MSM.  相似文献

HIV is rapidly spreading among men who have sex with men (MSM) in China. We estimate and compare rates of condom use among MSM in different regions of China through a systematic literature review. Meta-analyses were conducted over a final set of 66 studies to estimate national and regional condom use rates among MSM with different types of male sex partners. Country-wide, there has been a modest increase in reported condom use at last sex among MSM, from 56.1% (95% CI: 53.4–58.7%) in 2003–2005 to 61.6% (95% CI: 58.4–64.8%) in 2006–2008. Consistent condom use has also increased, from 32.5% (95% CI: 28.6–36.7%) in 2003–2005 to 36.3% (95% CI: 33.7–38.9%) in 2006–2008. Condom use was greatest and increasing among commercial sex partners, from 49.8 to 75.2% at last anal sex. Further condom promotion is still required to reduce the incidence of HIV infection among MSM in China.  相似文献

Recent findings highlight the continued rise in cases of HIV infection among racial/ethnic minority young men who have sex with men (YMSM). In adults, disclosure of HIV status has been associated with decreased sexual risk behaviors but this has not been explored among YMSM. In this study of 362 HIV-infected racial/ethnic minority YMSM, rates of disclosure were high, with almost all disclosing their status to at least one person at baseline. The majority had disclosed to a family member, with higher disclosure rates to female relatives compared with males. After adjustment for site, disclosure to sex partners and boyfriends was associated with an increase in condom use during both oral and anal sex. Future studies should consider skills training to assist youth in the disclosure process, facilitate how to determine who in their family and friend social network can be safely disclosed to and support family-based interventions.  相似文献

We conducted a case-control study to compare illicit substance and erectile dysfunction medication (EDM) use between recently HIV-infected and uninfected men who have sex with men (MSM). Eighty-six recently (previous 12 months) HIV-infected MSM (cases) and 59 MSM who recently tested HIV-negative (controls) completed computer-assisted self-interviews. There were no statistical differences in demographics or number of sexual partners by HIV status. Cases were more likely than controls to report methamphetamine or nitrite use, but not EDM, gamma hydroxybutyrate, 3,4 methylenedioxymethamphetamine, cocaine, or marijuana use, in the previous 12 months and with their last three sexual partners in multivariate logistic regression models. Use of nitrites and amphetamine may increase HIV risk among MSM.  相似文献

Although pre-exposure prophylaxis (PrEP) use is increasing among men who have sex with men (MSM), condoms remain key to HIV prevention. Implementation intentions—which link a behavioral action plan with a situation or cue—may predict condom use. The Strength of Implementation Intentions Scale (SIIS), which assesses condom use implementation intentions, has not been evaluated among MSM. A structural model tested whether the SIIS mediated the relationship between condom use intentions and condomless sex acts among 266 sexually-active MSM (56% White, 26% Black, 15% Latino, Mage = 32.54). After controlling for PrEP use, HIV-status, and demographics (χ2(107) = 140.06, CFI = 0.98, TLI = 0.97, RMSEA = 0.03), the SIIS fully mediated the relationship between condom use intentions and condomless sex acts. The SIIS can serve as a fidelity check for interventions, a mediator in theoretical models, and future studies should incorporate implementation intentions into HIV prevention interventions for MSM.  相似文献

As part of a study to develop effective Internet-based HIV prevention interventions for Men who use the Internet to seek Sex with Men (MISM), we sought information from the target population on; (a) acceptability of sexually explicit media; (b) interest in specific content areas; and (c) identification of credible sources of information. A cross-sectional stratified Internet-based survey design was employed. Between September and November 2005, we recruited 2,716 MISM through Gay.com stratified across race/ethnicity to ensure adequate racial/ethnic diversity. Sixteen Likert-type items assessed acceptability of sexual explicitness, 24 items identified topics for inclusion, and two assessed sources of information. There was near universal acceptability for highly sexually explicit education. Over 75% reported high interest in 10 sexual health topics. HIV positive MISM and MISM engaged in unprotected anal sex with multiple male partners reported significantly less interest in HIV prevention specific content. Differences across age, race/ethnicity and education were identified. Idiosyncratic searches and gay sites were frequently cited sources of information; however blogs, government, and media sites were not. It is acceptable for web-based HIV prevention for MISM to be highly sexually explicit and to provide detailed content relevant to men’s sexual health. Since demographic differences in acceptability and content were minor, it is appropriate for interventions to target across demographics. Interventions to re-engage men engaging in high risk and HIV + MISM should be considered. Leading health agencies should review whether their web information is retrievable, credible and useful to those most at risk.  相似文献

We examined individual-level, partnership-level, and sexual event-level factors associated with condom use during receptive anal intercourse (RAI) among 163 low-income, racially/ethnically diverse, HIV-negative men who have sex with men (MSM) in Los Angeles (2007–2010). At baseline, 3-month, and 12-month visits, computer-assisted self-interviews collected information on ≤3 recent male partners and the last sexual event with those partners. Factors associated with condom use during RAI at the last sexual event were identified using logistic generalized linear mixed models. Condom use during RAI was negatively associated with reporting ≥ high school education (adjusted odds ratio [AOR] = 0.32, 95 % confidence interval [CI] 0.11–0.96) and methamphetamine use, specifically during RAI events with non-main partners (AOR = 0.20, 95 % CI 0.07–0.53) and those that included lubricant use (AOR = 0.20, 95 % CI 0.08–0.53). Condom use during RAI varies according to individual-level, partnership-level, and sexual event-level factors that should be considered in the development of risk reduction strategies for this population.  相似文献

The aim of this meta-analysis was to explore whether the constructs in the theory of planned behaviour (TPB; i.e., attitude, subjective norm, perceived behavioural control, intention) explain condom use behaviour among men who have sex with men (MSM). Electronic databases were searched for studies that measured TPB variables and MSM condom use. Correlations were meta-analysed using a random effects model and path analyses. Moderation analyses were conducted for the time frame of the behavioural measure used (retrospective versus prospective). Attitude, subjective norm and perceived behavioural control accounted for 24.0 % of the variance in condom use intention and were all significant correlates. Intention and PBC accounted for 12.4 % of the variance in condom use behaviour. However, after taking intention into account, PBC was no longer significantly associated with condom use. The strength of construct relationships did not differ between retrospective and prospective behavioural assessments. The medium to large effect sizes of the relationships between the constructs in the TPB, which are consistent with previous meta-analyses with different behaviours or target groups, suggest that the TPB is also a useful model for explaining condom use behaviour among MSM. However, the research in this area is rather small, and greater clarity over moderating factors can only be achieved when the literature expands.  相似文献

In some studies, situational factors have been shown to be stronger predictors of condomless sex than individual risk factors. Cross-sectional relationships between condomless anal sex (CAS) with HIV-serodiscordant partners and risk factors across ecological levels (individual, sexual environment) were examined using a sample (N = 60) of HIV-positive men who have sex with men (MSM) who reported multiple recent episodes of CAS. Negative binomial regressions were used to evaluate the association of contextual risk factors (e.g., substance use during sex, transactional sex, public sex, sex at a sex party) with recent condomless sex, controlling for demographics and mental health. Results demonstrated that sexual environment factors, particularly sex under the influence of drugs or alcohol (B = .019, p < .05), transactional sex (B = .035, p < .01), and public sex (B = .039, p < .01) explained a large proportion of the variance in CAS. Only sex at a sex party was not related to CAS (p = .39). For each additional sexual environment in which men engaged, their rates of CAS increased (B = .39, p < .01). Secondary prevention interventions that are tailored to the proximal sexual environment could be maximally effective, particularly if they address substance use and other challenging sexual situations.  相似文献

Alcohol use is a public health problem in the Russian Federation. This study explored relationships between alcohol use and behavioral risks for HIV transmission among men who have sex with men (MSM) in Moscow, Russia. Alcohol use disorder identification test (AUDIT) scores for 1367 MSM participating in a cross-sectional survey and HIV testing were categorized to: “abstinence/low use”, “hazardous use”, “harmful use/dependency”. Multiple logistic regression models compared dependent variables for sexual and drug use behaviors across alcohol use strata. Hazardous and harmful/dependent alcohol use were significantly associated with high-risk sexual behaviors and drug use. Harmful use/dependency was associated with an increased odds of having more than five male sex partners (last 12 months; adjusted odds ratios—AOR 1.69; 95 % CI 1.25–2.27), inconsistent condom use during anal intercourse (AOR 2.19; 95 % CI 1.61–2.96) and, among those using recreational drugs, injection drug use (last month; AOR 4.38: 95 % CI 1.13–17.07) compared to abstinent/low-level users. Harmful/dependent use was marginally associated with HIV infection (AOR 1.48; 95 % CI 0.97–2.25). HIV prevention efforts for MSM in Moscow may benefit from addressing problem alcohol use to mitigate high-risk behaviors.  相似文献

Information about a specific sexual event can shed light on factors that facilitate or impede condom use. Data were collected by a random digit-dialing telephone survey of unmarried Latino adults in 10 states with large Latino populations. In multivariate analyses, among heterosexually active unmarried Latino men (n = 591), those who reported having a condom available, engaging in a conversation about condoms, having a non-steady, casual partner or a one-time partner, were more likely to use condoms. Men were more likely to use condoms when no other birth control was used or pregnancy was not possible than other men. Findings were similar for both low and high acculturated men. Interventions that increase condom availability may be particularly useful for reducing HIV risk among Latino heterosexual men. An erratum to this article can be found at  相似文献

HIV infections in Peru are concentrated among men who have sex with men (MSM) and transgender women (TW). HIV testing rates among them remain low, delaying entrance into care. We assessed the prevalence of frequent HIV testing (at least every 6 months) and associated factors among 310 MSM and TW who attend sexual health clinics in Lima, Peru, and who reported that they were HIV seronegative or unaware of their status. Only 39% of participants tested frequently, and 22% had never tested; 29% reported that they were at low or no risk for acquiring HIV. Reporting low or no risk for acquiring HIV was associated with frequent testing (adjusted prevalence ratio [aPR] = 1.53, 95% CI 1.13–2.08); those reporting unprotected anal sex were less likely to test frequently (aPR = 0.66, 95% CI 0.50–0.87). HIV prevalence was 12% and did not vary by risk perception categories. This at-risk population tests infrequently and may not understand the risk of having unprotected sex.  相似文献

Young men who have sex with men (YMSM) are the only group in which rates of new HIV infections are increasing in the United States. Alcohol and drug use have been linked to HIV risk, but evidence suggests that these associations may change across development and by relationship type. Data were taken from an analytic sample of 114 YMSM enrolled in a longitudinal study of lesbian, gay, bisexual and transgender youth with 4 years of participant follow-up. For the sample as a whole, alcohol use before sex was not associated with sexual risk, but drug use before sex was positively associated with sexual risk. A positive association between alcohol use and sexual risk emerged across development, and this association was stronger in serious relationships relative to casual sex partners. The positive association between drug use before sex and sexual risk decreased across development and was stronger in serious relationships. We discuss the need for addressing substance use before sex in dyadic interventions with YMSM.  相似文献

Depression and methamphetamine use have been associated with increased sexual risk-taking among men who have sex with men (MSM). This study estimated associations between current major depressive episode and/or methamphetamine use disorder and engagement in condomless anal intercourse (CAI). From March 2014 thru January 2016, 286 methamphetamine-using MSM were enrolled into a RCT to reduce methamphetamine use and sexual risk-taking. Analyses revealed that current major depressive episode was associated with a 92% increase in the rate of engagement in CAI with casual male partners (IRR 1.92; 95% CI 1.12–3.31) and a 76% increase in the rate of engagement in CAI with anonymous male partners (IRR 1.76; 95% CI 1.00–3.09). Additionally, for each unit increase in diagnostic methamphetamine use disorder severity, rates of engagement in CAI with anonymous male partners increased by 44% (IRR 1.44; 95% CI 1.11–1.87) and rates of engagement in CAI with exchange male partners increased by 140% (IRR 2.40; 95% CI 1.39–4.13). Neither diagnosis was associated with CAI with main male partners. Depression and methamphetamine use influence sexual risk-taking in unique ways, and interventions working with MSM should assess participants for both depression and methamphetamine use, and may tailor intervention content based on diagnostic outcomes.  相似文献

Research demonstrates a consistent association between substance use and sexual risk, particularly among men who have sex with men (MSM). The present study builds upon two existing theories (Cognitive Escape Theory and Expectancy Theory) to examine the synergistic role of sexual conflict (surrounding unsafe sex) and expectancies in sexual behavior among 135 MSM. Two conflicts were examined: (1) The conflict between motivation to practice safer sex and temptation for unprotected sex; and (2) The conflict between motivation to practice safer sex and perceived benefits of unprotected sex. Factorial ANOVAs (2 × 2; high versus low expectancies and conflict versus no conflict) revealed a significant interaction between conflict and expectancies—individuals who reported high levels of conflict were more sensitive to the effect of expectancies than were those experiencing low levels of sexual conflict. Results demonstrate the synergistic effects of conflict and expectancies and highlight the importance of integrating existing theories to more fully consider the intrapsychic operation and experience of sexual conflicts.  相似文献

This study assessed the prevalence of exchanging sex for money or drugs among men who have sex with men (MSM) in the 2011 US National HIV Behavioral Surveillance system. Prevalence of HIV, being HIV-positive but unaware (HIV-positive–unaware), risk behaviors and use of services were compared between MSM who did and did not receive money or drugs from one or more casual male partners in exchange for oral or anal sex in the past 12 months. Among 8411 MSM, 7.0 % exchanged sex. MSM who exchanged sex were more likely to be non-Hispanic black, live in poverty, have injected drugs, have multiple condomless anal sex partners, be HIV-positive and be HIV-positive–unaware. In multivariable analysis, exchange sex was associated with being HIV-positive–unaware (aPR 1.34, 95 % CI 1.05–1.69) after adjusting for race/ethnicity, age, education, poverty, and injecting drugs. MSM who exchange sex represent an important group to reach with HIV prevention, testing, and care services as they were more likely to report behavioral risk factors that put them at risk of HIV.  相似文献
