This study examines correlates of unprotected sexual risk practices of an ethnically diverse sample of HIV-seropositive men who have sex with men (MSM) from the New York City and San Francisco metropolitan areas. Participants completed a self-report survey that assessed sexual risk behaviors and potential correlates. A total of 367 men reported sex with a casual male partner in the previous 3 months. Participants were divided into three groups based on level of HIV-transmission risk with HIV negative or unknown-status partners: no unprotected anal sex (58.9%), unprotected receptive anal sex only (14.2%), and unprotected insertive anal sex (22.6%). Multivariate logistic regression analyses indicated that men reporting unprotected anal insertive sex perceived less responsibility to protect their partners from HIV. Men reporting no unprotected anal sex also reported less use of nitrate inhalants, lower temptation for unsafe sex, and fewer HIV-negative and unknown-status partners. Men reporting unprotected receptive anal sex were less anxious than the other two groups but also reported greater depression than those not reporting unprotected anal sex and greater loneliness than those reporting unprotected anal insertive sex. Implications for interventions with HIV-positive MSM are presented. 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

This study used qualitative methods to explore the social and psychological context of sexual behavior and HIV risk among African American non-gay-identified men who have sex with men. Analysis of men's narratives on their sexual behaviors revealed four social and psychological factors contributing to risk for HIV infection: (a) a tendency to compartmentalize and personally disengage from same-sex behavior, (b) traditional gender roles that reinforce men's adherence to masculine images and ambivalent attitudes toward women, (c) cultural norms that favor secrecy and privacy about any personal matters, and (d) spontaneous and unplanned sexual episodes with other men. Findings indicate that innovative HIV prevention and risk reduction strategies are necessary to reach this group and question the legitimacy of conventional sexual orientation categories for these men. Interventions must address social contextual determinants of risk, reinforce men's public identifications as straight/heterosexual, and maintain men's need for privacy about same-sex behaviors. 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

Previous studies have indicated an association between childhood sexual abuse (CSA) and adult sexual risk behaviour among women and among men who have sex with men (MSM). However, no studies to date have tested the hypothesis that a history of CSA predicts sexual behaviour carrying risk of transmission of HIV to others, i.e. in a known HIV-positive cohort. The present study tested this hypothesis among a sample of 456 HIV-positive MSM recruited from community venues in New York and San Francisco. CSA history was found to be significantly associated with past (in the last 90 days) unprotected anal sex acts, both insertive (33% versus 20%, p < 0.05) and receptive (43% versus 27%, p < 0.02), with partners of HIV-negative or unknown serostatus. Further, several potential mediators of this effect were tested, and three found to be predicted by CSA history. Each of these potential mediators was associated with sexual risk behaviour, but differentially: anxiety and hostility were significantly associated with insertive acts, while anxiety, hostility and suicidality were associated with receptive acts. Mediation analyses supported the hypothesis that these factors significantly (albeit partially) accounted for the association of CSA with receptive anal intercourse. Nonsignificant mediation effects were found for insertive sex, suggesting the operation of unmeasured mediating variables. These results highlight the importance of mental health services for individuals who have been sexually abused, both for personal and for public health benefit, and also indicate a need for further research into mediators of CSA effects on transmission-related behaviour. 相似文献

A probability sample of 206 men who have sex with men from 16 sites in Phnom Penh were surveyed about sexual behaviors and tested for HIV and sexually transmitted infections (STIs). HIV and syphilis prevalence was 14.4% and 5.5%, respectively. Out of the total sample, 81% reported anal sex with any male partners in the past 6 months, and 61.2% reported having had vaginal sex. In the past 6 months, 82.8% of the sample reported having male partners who paid them to have sex. Self-reported sexual orientation did not match well with self-reported sexual behavior. Significant risk factors for HIV infection were anal sex with multiple partners, unprotected vaginal sex with commercial female partners in the past month, and any STI. Complex sexual networks indicate that men who have sex with men act as a bridge between higher and lower HIV prevalence populations. Better prevention efforts structured around behaviors rather than sexual identities are needed. 相似文献

The present study aimed to determine whether the experience of bias-motivated bullying was associated with behaviors known to increase the risk of HIV infection among young men who have sex with men (YMSM) aged 18–29, and to assess whether the psychosocial problems moderated this relationship. Using an Internet-based direct marketing approach in sampling, we recruited 545 YMSM residing in the USA to complete an online questionnaire. Multiple linear regression analyses tested three regression models where we controlled for sociodemographics. The first model indicated that bullying during high school was associated with unprotected receptive anal intercourse within the past 12 months, while the second model indicated that bullying after high school was associated with engaging in anal intercourse while under the influence of drugs or alcohol in the past 12 months. In the final regression model, our composite measure of HIV risk behavior was found to be associated with lifetime verbal harassment. None of the psychosocial problems measured in this study – depression, low self-esteem, and internalized homonegativity – moderated any of the associations between bias-motivated bullying victimization and HIV risk behaviors in our regression models. Still, these findings provide novel evidence that bullying prevention programs in schools and communities should be included in comprehensive approaches to HIV prevention among YMSM. 相似文献

Vengeance is defined as a continuum of thoughts and/or actions ranging from harmless thoughts to destruction or death, due to feelings of hurt or anger, as a result of a perceived personal attack. Studies assessing the association between vengeance and HIV risk behavior are extremely lacking. The primary aims of this study were to examine the associations between vengeance and sexual compulsivity (SC), and self-efficacies (SEs) for condom use, HIV disclosure, and negotiation of safer sex practices. Data were obtained from 266 men who have sex with men (MSM) living with HIV. Simple and multiple linear regression were used to explore the associations between vengeance, SC and SE. After adjusting for sociodemographic and HIV-related factors, there was a negative association between vengeance and SE for HIV disclosure: (most vengeful: β?=??1.49; 95% CI: ?2.40, ?0.58; more vengeful: β?=??1.17; 95% CI: ?2.12, ?0.22; vengeance (continuous: β?=??0.03; 95% CI: ?0.05, ?0.01). Intervention programs geared towards improving SE for HIV disclosure among MSM living with HIV should endeavor to reduce vengeful feelings. 相似文献

Self-reported sexual behaviour and HIV risk taking among men who have sex with men in Fortaleza, Brazil. 总被引:4,自引:0,他引:4
OBJECTIVES: To describe and identify sociodemographic and behavioural characteristics and other factors related to high-risk behaviour for HIV infection of men who have sex with men (MSM) living in Fortaleza, Brazil. METHODS: A survey was carried out among 400 MSM aged 14-65 years and recruited through the snowball technique or in gay-identified venues. A semi-structured questionnaire was conducted among them. Logistic regression analysis was used to model the dichotomous outcome (high risk or low risk). RESULTS: Forty-four per cent of the participants reported engaging in high-risk sexual behaviour in the previous year. MSM less informed about AIDS, reporting more sexual partners, reporting at least one female partner in the previous year, having anal sex as the favourite way to have sex, and having great enjoyment of unprotected anal sex were more likely to be engaged in risky behaviour. Twenty-three per cent of participants reported at least one sexual contact with women during the previous year. Two-thirds of men who had unprotected sex with their female partners also had unprotected anal sex with their male partners. CONCLUSIONS: A large proportion of MSM in Fortaleza still remain at elevated risk for contracting HIV infection. The factors predictive of high-risk sexual behaviour are significant in spreading HIV infection among the MSM population and also among their female partners. The lifestyles of these men are different to those of men from other parts of Brazil or outside the country. Preventive interventions need to be culturally and socially specific in order to be effective. 相似文献

Culturally relevant prevention programs are required to reduce HIV risk exposure of Latino young men who have sex with men (YMSM). As part of Hermanos Jóvenes, 465 Latino YMSM were surveyed at community venues of New York City outside the gay-identified area of lower Manhattan. We examined factors that influence ethnic and gay community attachments; the association between community attachments and social support in sexual matters; and the relationship between levels of attachment, social support in sexual matters, and sexual risk behaviors. Sixty-eight percent felt closely connected to their ethnic community; about 34% were highly attached to both neighborhood and New York City gay communities. Greater social support in sexual matters was associated with ethnic and gay community attachments. Latino YMSM connected to their ethnic community were about 40% less likely to report recent unprotected anal intercourse (UAI) with a male partner, and 60% less likely to have engaged in UAI during the last sexual contact with a nonmain male partner. Gay community attachment was not significantly related to risk behaviors. Findings point to the importance of ethnic ties and involving ethnic community organizations in HIV prevention efforts. 相似文献

Explaining disparities in HIV infection among black and white men who have sex with men: a meta-analysis of HIV risk behaviors 总被引:5,自引:0,他引:5
OBJECTIVE: To identify factors that contribute to the racial disparity in HIV prevalence between black and white men who have sex with men (MSM) in the United States. METHODS: A comprehensive literature search of electronic databases, online bibliographies, and publication reference lists yielded 53 quantitative studies of MSM published between 1980 and 2006 that stratified HIV risk behaviors by race. Meta-analyses were performed to compare HIV risks between black and white MSM across studies. RESULTS: Compared with white MSM, black MSM reported less overall substance use [odds ratio (OR), 0.71; 95% confidence interval (CI), 0.53-0.97], fewer sex partners (OR, 0.64; 95% CI, 0.45-0.92), less gay identity (OR, 0.29; 95% CI, 0.17-0.48), and less disclosure of same sex behavior (OR, 0.42; 95% CI, 0.30-0.60). HIV-positive black MSM were less likely than HIV-positive white MSM to report taking antiretroviral medications (OR, 0.43; 95% CI, 0.30-0.61). Sexually transmitted diseases were significantly greater among black MSM than white MSM (OR, 1.64; 95% CI, 1.07-2.53). There were no statistically significant differences by race in reported unprotected anal intercourse, commercial sex work, sex with a known HIV-positive partner, or HIV testing history. CONCLUSIONS: Behavioral risk factors for HIV infection do not explain elevated HIV rates among black MSM. Continued emphasis on risk behaviors will have only limited impact on the disproportionate rates of HIV infection among black MSM. Future research should focus on the contribution of other factors, such as social networks, to explain racial disparities in HIV infection rates. 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

This study is among the first to examine the sexual risk behaviors and attendant factors of young men who have sex with men (YMSM) in Hong Kong using location-aware gay social networking mobile applications (“gay apps”). Among the 213 YMSM (Mage?=?21.52, SD?=?2.29 years, range 17–25) who reported their recent (past six months) sexual history with male partners and gay apps use, inconsistent condom use (ICU) during anal sex was fairly common (60.2% regular partners, 45.8% non-regular partners). One-fifth of the sample reported condomless internal ejaculation (CIE) during anal sex (19.3% insertive, 19.8% receptive). Frequent “Grindr” and “Jack'd” users were less likely to report anal sex, and hence ICU, with regular [adjusted odds ratio (AOR)?=?0.72] and non-regular (AOR?=?0.62) partners, respectively. Sexual partnering via apps doubled the odds of ICU with both regular (AOR?=?1.99) and non-regular (AOR?=?2.17) partners. The odds of ICU with regular partners also increased with relationship status (AOR?=?2.86 exclusive, AOR?=?3.23 non-exclusive) but reduced for those who never had STI/HIV testing (AOR?=?0.27). With non-regular partners, YMSM's likelihood of ICU increased with more recent partners (AOR?=?3.25) and drug use (AOR?=?3.79), but reduced with group sex (AOR?=?0.15). The odds of receptive CIE increased with alcohol consumption (AOR?=?4.04), non-exclusive relationship (AOR?=?4.10), and more recent partners (AOR?=?2.47), but reduced with group sex (AOR?=?0.15) and older age (AOR?=?0.84). For insertive CIE, the odds increased with bisexual YMSM (AOR?=?2.89), exclusive relationship (AOR?=?3.97), and longtime apps-use (AOR?=?1.81). The findings identify meaningful differences among YMSM app-users that inform sexual health intervention and suggest attention on alcohol or drug use during sex and condomless sex with non-exclusive regular partners. 相似文献
