Gender role conflict may influence condom use among black MSM. We examined relationships between the Gender Role Conflict Scale (GRCS), social/demographic variables and condom use among 456 black MSM. Higher total GRCS scores did not predict unprotected insertive anal intercourse (UIAI) or unprotected receptive anal intercourse (URAI) with men, but were associated with unprotected vaginal or anal intercourse (UVI/UAI) with women among bisexually active participants (n?=?69). Higher perceived HIV risk reduced the likelihood of both UIAI and URAI with men. Internet recruitment venues, sexual discrimination experiences, higher numbers of sex partners and UVI/UAI with women all increased the likelihood of UIAI with men, while education (college/technical school or college degree) was associated with URAI with men. Future sexual health interventions for black MSM should emphasize broader social/demographic and alternative gender role variables with male sexual partners, while traditional GRCS variables may prove useful among those with female sexual partners.  相似文献

This article examined, in a sample of 219 HIV-positive Latino men who have sex with men (MSM), a set of three variables that can shape the context of sexual encounters between men and influence sexual risk behaviors: disclosure of positive HIV serostatus, seroconcordance of partners, and relationship between partners. Participants from Boston, New York, and Washington completed a survey in English or Spanish using computer-assisted self-interview technology with audio enhancement. At the bivariate level, disclosure, seroconcordance, and partner relationship were all interrelated, as well as associated with the likelihood of unprotected intercourse. Unprotected anal intercourse with the most recent partner was more likely when the partner (a) knew that the participant was HIV-positive, (b) was the participant's main partner, and (c) was himself also HIV-positive. A logistic set regression revealed that the set of three variables added significantly to the prediction of unprotected anal intercourse, beyond demographic variables of income, education, and age. In the multivariate model, however, of the three, only seroconcordance achieved significance. The importance of a contextual approach to understanding sexual risk behavior was discussed.  相似文献

Risk factors for HIV infection among men who have sex with men   总被引:21,自引:0,他引:21  
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

OBJECTIVES: To describe knowledge of primary and secondary sexual partner's HIV serostatus and sexual practices, including serosorting, among men who have sex with men (MSM) living in California. METHODS: Men who self-identified as gay/bisexual in the 2001 California Health Interview Survey, a statewide biennial random-digit-dial survey interviewing more than 50,000 adults on a variety of health topics, were recontacted in 2002 and interviewed by telephone about injection drug use, their own and partner's HIV serostatus, and sexual risk behaviors. RESULTS: Among 220 men who reported a primary partner, 86% [95% confidence interval (CI): 77-92] knew their primary partner's serostatus; 62% (95% CI, 52-70) of the 250 men who reported a secondary partner knew their most recent secondary partner's HIV serostatus. Knowledge of one's most recent secondary partner's HIV serostatus was inversely related to history of injecting recreational drugs (odds ratio, 0.22; P < 0.01), and reporting a primary partner in the past year (odds ratio, 0.37; P < 0.05). Two-fifths (41%) of HIV-positive men and three-fifths (62%) of HIV-negative men engaged in serosorting (serocordant unprotected anal intercourse) with their primary partners, whereas 33% HIV-positive men and 20% HIV-negative men did so with their most recent secondary partners. CONCLUSIONS: This population-based survey documented the extent to which MSM know their partners' serostatus and practice serosorting behaviors. The findings emphasize the need for studies to report serocordant and serodiscordant unprotected anal intercourse separately, as the former presents significant lower risk of HIV transmission.  相似文献

OBJECTIVE: To investigate longitudinally the association between highly active antiretroviral therapy (HAART)-related beliefs and the change from protected to unprotected anal intercourse with casual partners on an individual level. METHODS: The study population included 217 HIV-negative homosexual men participating in the Amsterdam Cohort Study from September 1999 to May 2002, including five data waves with a 6-month interval. The selection criteria were: being under 31 years of age, having had anal sex with casual partners in the preceding 6 months, and participating in at least two data waves. Information was collected on the individual change from protected to unprotected receptive anal intercourse (URAI) and unprotected insertive anal intercourse (UIAI) and the level of agreement with different HAART-related beliefs. RESULTS: The majority of men disagreed with the three treatment-belief factors that resulted from the principal component analysis: perceiving less HIV/AIDS threat since HAART, perceiving less need for safe sex since HAART, and perceiving high effectiveness of HAART in curing HIV/AIDS. Multivariate analyses revealed that the more men inclined to agree with the belief 'perceiving less HIV/AIDS threat', the more likely they were to change to URAI (adjusted OR 1.60; 95% CI 1.16-2.22). CONCLUSION: Homosexual men are quite realistic about the effectiveness of HAART, the continued need for condom use, and the HIV/AIDS threat since HAART. However, a tendency towards agreement with 'perceiving less HIV/AIDS threat' was found to predict an individuals' change to URAI. This finding supports the hypothesis of a causal relationship between decreased HIV/AIDS threat since HAART and a change to URAI.  相似文献

Young Asian and Pacific Islander (API) men who have sex with men (MSM) are at high risk for HIV, but little is known about their risk behavior. We examined the patterns and predictors of unprotected anal intercourse among 253 API MSM aged 15-25 recruited from gay-identified venues in Seattle, Washington, and San Diego, California, from May to August 1999. Overall, 33% reported unprotected anal intercourse in the past 3 months. Multivariate analyses found that unprotected anal intercourse was associated with self-identifying as gay or bisexual, having multiple sexual partners, having sex with a steady partner, having been tested for HIV, and not perceiving peer norms supportive of safer sex. Young API MSM engage in unprotected sex at high rates. There is an urgent need to help these men reduce sexual risk behavior by implementing HIV prevention programs that address the issue of self-accepting sexual orientation, the potential problem with using HIV testing as a risk reduction strategy, the possible risk of HIV transmission in steady relationships and multiple sexual partnerships, and the importance of establishing safer sex practices as peer norms.  相似文献

We examined the association between HIV/AIDS risk behaviors and romantic feelings among single, young gay and bisexual men (YGBM). Romantic feelings may have positive (romantic ideation) and negative (romantic obsession) connotations. Consequently, we hypothesized that YGBM would report greater risks if they reported having obsessive thoughts about their relationship desires; conversely, we hypothesized that YGBM who envision a romantic relationship would report fewer unprotected partners. Using cross-sectional data from a study examining YGBM's online dating experiences (N = 376; ages 18-24), we found a positive association between romantic obsession and number of partners for unprotected receptive (URAI) and insertive (UIAI) anal intercourse. Conversely, we found a negative association between romantic ideation and number of partners for URAI and UIAI. Is love risky or protective? Our results indicate support for both perspectives. We discuss the implications of our findings, highlighting the importance of addressing romantic pursuits into existing HIV prevention interventions for YGBM.  相似文献

China is experiencing an emerging HIV epidemic among men who have sex with men (MSM). We investigated sexual risk, risk perception, HIV and condom knowledge, and utilization of prevention services in the first large sample of MSM recruited in Beijing. Four hundred eighty-two MSM were sampled from September 2001 to January 2002. Forty-nine percent of participants reported unprotected anal intercourse with men during the previous 6 months. However, only 15% perceived they are at risk for HIV and many had misconceptions about HIV transmission routes and limited knowledge about condoms. Less than one quarter obtained free condoms (24%) and condom lubricants (19%) in the past 2 years. Multiple logistic regression analysis showed that unprotected insertive anal intercourse was associated with not having a Beijing residence card, having six or more male sexual partners, not having sex with women, having a lifetime history of sexually transmitted diseases (STDs), and having never tested for HIV. Unprotected receptive anal intercourse was independently associated with having six or more male sexual partners, not having sex with women, having a lifetime history of STDs, having never tested for HIV, and having less exposure to HIV prevention services. In addition, 28% reported having sex with both men and women during the previous 6 months, and 11% had unprotected intercourse with both men and women. This finding suggests that MSM are a potential bridge of HIV transmission to heterosexual women (or vice versa) and that addressing the HIV prevention needs of MSM may benefit the wider population.  相似文献

Adolescent and young adult males who have sex with men (MSM) remain at high risk of HIV infection. Many sexual risk factors have been identified, yet the role of substance use remains controversial. We assess the extent to which urban young MSM report being "high" on drugs or alcohol during sex and the association between being "high" and unprotected anal intercourse (UAI). During summer 2000, 3,075 MSM aged 15-25 years completed a 20-minute interview for the Community Intervention Trial for Youth Project. Participants were asked about their last sexual contact with main and nonmain partners, including whether they were "high on drugs or alcohol." 18.6% of MSM with a main partner reported being high during their last sexual encounter; 25.0% reported UAI. Among men with a nonmain partner, 29.3% reported being high, and 12.3% reported UAI. Being high was associated with unprotected receptive anal intercourse with nonmain partners (odds ratio = 1.66, p = .02). HIV prevention should include messages about the potential dangers of drinking and drug use in situations where sexual encounters with nonmain partners may occur.  相似文献

Much research has examined the relationship between depressive symptoms and unprotected sex among men who have sex with men (MSM), but little is known about how depression is related to the sexual behavior of men who intentionally engage in unprotected anal intercourse, or bareback sex. In this study, we explored the extent to which depressive symptoms were associated with rates of unprotected sex among barebackers, and whether this relationship was dependent upon HIV serostatus. Using a sample of 120 MSM who engage in intentional condomless sex, we found that for HIV-negative participants, depressive symptoms were associated with the overall frequency of unprotected anal intercourse as well as unprotected anal intercourse with a serodiscordant partner. For HIV-positive participants, depressive symptoms were not associated unprotected intercourse. Additional research is needed to better understand depression among men who bareback and how interventions could be designed to address depression and reduce sexual risk behaviors.  相似文献

This study used logistic regression analysis to identify psychosocial predictors of unprotected anal intercourse in a sample of 212 HIV positive gay men who were enrolled in a sexual risk reduction intervention. A combination of five psychosocial variables (i.e., age, avoidant coping, loneliness, depressive symptoms, and impulsivity) reliably discriminated between men who had engaged in unprotected anal intercourse (UAI) with HIV negative or serostatus unknown partners and those who had not engaged in this high risk behavior. Avoidant coping emerged as the best psychosocial predictor that distinguished between the two groups. Men who had UAI during the previous 4 months had significantly higher scores on avoidant coping as compared with the no-UAI group. These findings suggest the need to design intervention programs for HIV positive gay men that addresses coping strategies in the context of high-risk sexual behaviors.  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

HIV is a growing public health threat in Central and Eastern Europe. In Hungary and a number of other countries, men who have sex with men (MSM) account for a high proportion of HIV infections. However, there has been very little systematic study of the sexual risk practices and characteristics of MSM in this region. This study surveyed 469 MSM recruited in Budapest gay community venues in June 2001. Half the men (50%) engaged in unprotected anal intercourse (UAI) in the past 3 months. Of these, 40% of men's insertive and 50% of their receptive acts were unprotected, and 25% had multiple AI partners in the past 3 months. 17% of MSM exchanged sex for money, 26% had female partners in the past year, and condoms were used in only 23% of their vaginal intercourse occasions. Multivariate analyses showed that high-risk behaviour was predicted by not having condoms available when needed, weak risk reduction intentions, negative attitudes toward safer sex, being in a steady relationship, and having a bisexual orientation. Community-based HIV prevention programmes focused on the needs of gay or bisexual men in Central and Eastern Europe are urgently needed.  相似文献

As part of a larger investigation examining genetic immunity to HIV, we undertook a cross-sectional investigation of 97 HIV-seronegative men who have sex with men (MSM). Our aim was to better understand the factors to which these men attributed their HIV serostatus and to relate these attributions to sexual risk taking. Three beliefs were related to sexual risk taking with HIV-negative/status unknown casual partners: (a) medication treatment advances, (b) the low probability related to HIV transmission, and (c) a healthy immune system, capable of resisting infection. A multivariate regression model suggested that use of recreational drugs, in combination with the belief that treatment advances reduce the risk of HIV seroconversion, in part, may explain the frequency with which individuals engage in unprotected anal receptive intercourse. Our findings suggest that MSM who intentionally engage in unprotected anal sex may be influenced by perceptions that medical advances have mitigated the threat of HIV and corroborate previous studies depicting an intimate relationship between illicit drug use and sexual risk taking.  相似文献

Few studies have examined the psychosocial factors associated with sexual transmission behaviors among HIV-positive men who have sex with men (MSM), heterosexual men (MSW) and women. We enrolled 1,050 sexually active HIV-positive patients at seven HIV clinics in six US cities as part of a clinic-based behavioral intervention. We describe the sexual transmission behaviors and examine demographic, clinical, psychosocial, and clinic prevention variables associated with unprotected anal or vaginal intercourse (UAVI). Twenty-three percent of MSM, 12.3% of MSW and 27.8% of women engaged in UAVI with partners perceived to be HIV-negative or of unknown serostatus. Among MSM and MSW, having multiple partners and lower self-efficacy were associated with increased odds of UAVI. Self-rating one’s health status as excellent/very good was a risk factor for UAVI among MSM. Among women, binge drinking and stressful life events were associated with UAVI. These findings identify variables that warrant attention in targeted interventions.  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

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

"Seroadaptation" comprises sexual behaviors to reduce the risk of HIV acquisition and transmission based on knowing one's own and one's sexual partners' serostatus. We measured the prevalence of seroadaptive behaviors among men who have sex with men (MSM) recruited through time-location sampling (TLS) across three perspectives: by individuals (N = 1207 MSM), among sexual dyads (N = 3746 partnerships), and for sexual episodes (N = 63,789 episodes) in the preceding six months. Seroadaptation was more common than 100% condom use when considering the consistent behavioral pattern of individuals (adopted by 39.1% vs. 25.0% of men, respectively). Among sexual dyads 100% condom use was more common than seroadaptation (33.1% vs. 26.4%, respectively). Considering episodes of sex, not having anal intercourse (65.0%) and condom use (16.0%) were the most common risk reduction behaviors. Sex of highest acquisition and transmission risks (unprotected anal intercourse with a HIV serodiscordant or unknown status partner in the riskier position) occurred in only 1.6% of sexual episodes. In aggregate, MSM achieve a high level of sexual harm reduction through multiple strategies. Detailed measures of seroadaptive behaviors are needed to effectively target HIV risk and gauge the potential of serosorting and related sexual harm reduction strategies on the HIV epidemic.  相似文献

This study examines patterns of agreement, knowledge and practice which can prevent or facilitate HIV transmission among men who are in regular ('primary') male-to-male relationships. Data are from a national volunteer phone-in survey of homosexually-active men in Australia. A sub-sample of 1070 men from a larger sample (n=3039) were found to have one or more regular partners for longer than 6 months. Self-reported HIV serostatus of survey participant and his regular partner, type of agreement regarding anal intercourse both within and outside the regular relationship, and engaging in unprotected anal intercourse with regular and with casual partners were examined. Risk practice was defined as unprotected anal intercourse with a regular partner of different or unknown serostatus and/or unprotected anal intercourse with a casual partner. Agreements were classified as: negotiated safety (28.8%); no unprotected anal intercourse (33.6%); unsafe (10.6%) and no agreement (17.0%). Risk practice was reported by 17.8% of the men. Type of agreement was found to be the strongest predictor of risk practice. Negotiated safety agreements were common, and were kept on the whole. Men with unsafe agreements, although only a small proportion of men in relationships, had high levels of risk practice.  相似文献
