Sexual Risk Behavior of HIV-Positive Methamphetamine-Using Men Who Have Sex with Men: The Role of Partner Serostatus and Partner Type

This study examined the role of partner serostatus and partner type in relation to the sexual risk behaviors and disclosure practices of HIV-positive methamphetamine (meth)-using men who have sex with men (MSM). The sample consisted of 132 HIV-positive meth-using MSM who reported having both serodiscordant (i.e., HIV-negative and unknown serostatus) and seroconcordant (i.e., HIV-positive) partners. HIV-positive meth-using MSM engaged in significantly fewer acts of anal sex with serodiscordant partners as compared to seroconcordant partners. However, mean levels of unprotected anal and oral sex were high, and mean levels of protected sex were low for both seroconcordant and serodiscordant partners. Oral sex was practiced twice as often as anal sex; however, both types of sex were primarily unprotected. This pattern of risky sexual behavior was reported for steady, casual, and anonymous partners, regardless of partner serostatus. Despite high rates of unprotected sex, rates of HIV serostatus disclosure were consistently high for HIV-positive and HIV-negative steady, casual, and anonymous partners. However, rates of disclosure to unknown serostatus partners were low, particularly in relation to anonymous partners. Future research should address the reasons why HIV-positive meth-using MSM engage in risky sexual activity with serodiscordant partners, and HIV prevention programs for this population should emphasize the risks associated with unprotected sex with seroconcordant partners.     

Unprotected anal intercourse among HIV-positive men who have a steady male sex partner with negative or unknown HIV serostatus

OBJECTIVES: We sought to determine the prevalence and predictors of unprotected anal intercourse (UAI) among HIV-positive men who have a single steady male partner with negative or unknown HIV serostatus. METHODS: We analyzed behavioral surveillance data from HIV-positive men who have sex with men (MSM) interviewed in 12 states between 1995 and 2000. RESULTS: Of 970 HIV-positive MSM who had a single steady male sex partner with negative or unknown serostatus, 278 (29%) reported UAI during the previous year. In a subset of 674 men who were aware of their infection, 144 (21%) had UAI. Among the men who were aware of their infection, factors found to be predictive of UAI in multivariate modeling were heterosexual self-identification, crack cocaine use, no education beyond high school, and a partner with unknown serostatus. CONCLUSIONS: Even after learning of their infection, one fifth of HIV-positive MSM who had a single steady male partner with negative or unknown serostatus engaged in UAI, underscoring the need to expand HIV prevention interventions among these men.     

Sexual Risk Behaviors of HIV-Positive,HIV-Negative,and Serostatus-Unknown Black Men Who Have Sex with Men and Women

Black men who have sex with men and women (MSMW) are at high risk for HIV infection and transmission. This study compared the sexual risk behaviors of Black MSMW who self-reported being HIV-positive with those who reported being HIV-negative and those who did not know their HIV status. Respondent-driven sampling (RDS) was used to recruit 1,154 Black MSM in Philadelphia and New York who completed an audio computer-assisted self-interview (ACASI). Of these men, 212 had engaged in anal sex with male partners and vaginal or anal sex with female partners in the past 3 months. A quarter (23.6%; n = 50) of MSMW self-reported testing positive for HIV at their last test, 59.4% (n = 126) reported testing negative for HIV at their last test, and 17.0% (n = 36) reported never having an HIV test. Multivariate logistic regression analysis revealed that HIV-positive MSMW were much less likely than HIV-negative men and never-tested men to have engaged in unprotected intercourse with main male and main female partners perceived to be HIV-negative or of unknown serostatus. However, HIV-positive men were equally as likely as HIV-negative men to have unprotected intercourse with non-main male and non-main female partners perceived as HIV-negative or of unknown serostatus. Our findings indicate that some HIV-positive MSMW engage in unprotected sex that places female and male partners at risk for HIV infection. However, MSMW who have never taken an HIV test, or who have not been recently tested, may be a greater source of HIV transmission to their female and male partners.     

The Effects of Sexual Partnership and Relationship Characteristics on Three Sexual Risk Variables in Young Men Who Have Sex with Men

Young men who have sex with men (YMSM) in the United States are experiencing an alarming increase in HIV incidence. Recent evidence suggests that the majority of new HIV infections in YMSM occur in the context of serious relationships, which underscores the importance of examining predictors of sexual risk behavior in the context of sexual partnerships, including relationship type, sexual partner characteristics, and relationship dynamics. The current study aimed to evaluate relationship and sexual partnership influences on sexual risk behavior in YMSM, including differentiating between multiple sexual risk variables (i.e., any unprotected anal or vaginal intercourse, unprotected insertive anal or vaginal intercourse, and unprotected receptive anal intercourse). More serious/familiar partnerships were associated with more sexual risk across all three risk variables, while wanting a relationship to last was protective against risk across all three risk variables. Some variables were differentially linked to unprotected insertive sex (partner gender) or unprotected receptive sex (partner age, partner race, believing a partner was having sex with others, and partners repeated across waves). Sexual risk behavior in YMSM is inconsistent across sexual partnerships and appears to be determined in no small part by sexual partner characteristics, relationship dynamics, and sexual role (i.e., insertive or receptive partner). These influences are critical in understanding sexual risk in YMSM and provide important targets for intervention.     

Exploring Contextual Differences for Sexual Role Strain Among Transgender Women and Men Who Have Sex with Men in Lima,Peru

Sexual and gender politics inform relational expectations surrounding sexual experiences of Peruvian transgender women (TW) and men who have sex with men (MSM). We used the framework of sexual role strain, or incongruence between preferred sexual role and actual sexual practices, to explore potential conflicts between personally articulated identities and externally defined norms of gender and sexuality and its potential to increase HIV/STI risk. Cross-sectional individual- and dyad-level data from 766 TW and MSM in Lima, Peru were used to assess the partnership contexts within which insertive anal intercourse was practiced despite receptive role preference (receptive role strain), and receptive anal intercourse practiced despite insertive role preference (insertive role strain). Sexual role strain for TW was more common with non-primary partners, while for MSM it occurred more frequently in the context of a primary partnership. Receptive role strain was more prevalent for TW with unknown HIV status (reference: without HIV) or pre-sex drug use (reference: no pre-sex drug use). For homosexual MSM, receptive role strain was more prevalent during condomless anal intercourse (reference: condom-protected) and with receptive or versatile partners (reference: insertive). Among heterosexual or bisexual MSM, insertive role strain was more prevalent with insertive or versatile partners (reference: receptive), and less prevalent with casual partners (reference: primary). Our findings suggest TW and MSM experience different vulnerabilities during sexual role negotiation with different partner-types. Future studies should explore the impact of sexual role strain on condom use agency, HIV/STI risk, and discordances between public and private presentations of gender and sexual orientation.

     

Sexual Negotiation, HIV-Status Disclosure, and Sexual Risk Behavior Among Latino Men Who Use the Internet to Seek Sex with Other Men

As part of a wider study of Internet-using Latino men who have sex with men (MSM), we studied the likelihood that HIV-negative (n=200) and HIV-positive (n=50) Latino MSM would engage in sexual negotiations and disclosure of their HIV status prior to their first sexual encounters with men met over the Internet. We also analyzed the sexual behaviors that followed online encounters. Our results showed that both HIV-negative and positive men were significantly more likely to engage in sexual negotiation and serostatus disclosure on the Internet than in person. Those who engaged in sexual negotiations were also more likely to use condoms for anal intercourse. Compared to HIV-negative MSM, HIV-positive MSM were significantly less likely to disclose their serostatus, and 41% of them acknowledged having misrepresented their serostatus to a prospective sexual partner met over the Internet. Although similar proportions of HIV-positive and negative men had condomless anal intercourse, HIV-positive MSM were more likely to report lack of intention to use condoms. Pleasure was the reason most frequently cited for lack of condom use. Cybersex was reported by only one-fifth of the sample. We conclude that the Internet, an understudied milieu of sexual networking, may present new possibilities for the implementation of risk reduction strategies, such as the promotion of sexual negotiation prior to first in-person encounter and serostatus disclosure.     

Sexual Compulsivity and Sexual Risk in Gay and Bisexual Men

Much of our understanding of the association between the Sexual Compulsivity Scale (SCS) and sexual risk behavior among men who have sex with men (MSM) has been limited to samples of HIV positive MSM only. Using data from a community-based survey of gay and bisexual men (n = 1214), this analysis sought to further evaluate the association between the SCS and sexual risk behavior. The SCS was significantly associated with a variety of sexual risk behaviors, including having sex under the influence of club drugs, engaging in unprotected anal sex (receptive or insertive) with partners of the same and/or different HIV serostatus, identity as a barebacker, intentions to have bareback sex, number of recent sex partners, and temptation for unsafe sex. The SCS was also significantly associated with having engaged in a variety of specialized sexual behaviors (i.e., fetishes), many of which can increase HIV transmission risks. Finally, in multivariate analyses, the SCS significantly predicted unprotected sex with a non-main partner even when controlling for race, HIV serostatus, age, identity as a barebacker, and club drug use. These data indicate that the SCS may be able to serve as an indicator to detect HIV-associated sexual risk behavior in community-based samples of gay and bisexual men.

Psychosocial Predictors of Sexual HIV Transmission Risk Behavior among HIV-Positive Adults with a Sexual Abuse History in Childhood

Childhood sexual abuse (CSA) is associated with HIV sexual risk behavior. Although many psychosocial correlates of sexual risk among HIV-positive persons have been identified, studies predicting continued risk among HIV-positive adults with histories of CSA are limited. This cross-sectional study identified variables predictive of sexual transmission risk behavior among an ethnically diverse sample of 256 HIV-positive adults (women and men who have sex with men; MSM) with CSA histories. Participants were assessed for trauma symptoms, shame related to HIV and sexual trauma, substance use, coping style, and sexual risk behavior. Logistic regression analyses were conducted to identify variables predictive of unprotected sexual behavior in the past 4 months. Unprotected sex was significantly associated with substance use and trauma-related behavioral difficulties among women and men, and less spiritual coping among men. Unprotected sex with HIV negative or serostatus unknown partners was significantly associated with greater trauma-related behavioral difficulties, more HIV-related shame, and fewer active coping strategies. Thus, trauma symptoms, shame, coping style, and substance use were significantly associated with sexual risk behavior among HIV-positive adults with histories of CSA, with models of prediction differing by gender and partner serostatus. HIV prevention intervention for persons with HIV and CSA histories should address trauma-related behavioral difficulties and enhance coping skills to reduce sexual transmission risk behavior.     

Per-contact risk of human immunodeficiency virus transmission between male sexual partners.

The risk of human immunodeficiency virus (HIV) transmission from various types of homosexual contact, including oral sex, is of biologic, epidemiologic, and public health importance. The per-contact risk of acquiring HIV infection from specific acts was estimated in a prospective cohort study of 2,189 high-risk homosexual and bisexual men, conducted in San Francisco, California; Denver, Colorado; and Chicago, Illinois, in 1992-1994. During 2,633 person-years of follow-up, 60 seroconversions were observed. The estimated per-contact risk of acquiring HIV from unprotected receptive anal intercourse (URA) was 0.82 percent (95% confidence interval: 0.24, 2.76 percent) when the partner was known to be HIV+ and 0.27 percent (95% confidence interval: 0.06, 0.49 percent) when partners of unknown serostatus were included. There was heterogeneity in per-contact risk, with nine seroconversions occurring after only one or two episodes of URA. The per-contact risk associated with unprotected insertive anal and receptive oral sex with HIV-positive or unknown serostatus partners was 0.06 and 0.04 percent, respectively. URA accounted for only 15 percent of all reported sexual activity by seroconverters. As lower-risk practices become more common, they may play a larger role in propagating the epidemic and should also be addressed by interventions targeting high-risk homosexual and bisexual men.     

Relationship Characteristics and HIV Transmission Risk in Same-Sex Male Couples in HIV Serodiscordant Relationships

Unprotected anal intercourse (UAI) remains a main risk factor for HIV among men who have sex with men (MSM) and this is of particular concern for partners of HIV serodiscordant status. However, HIV transmission risk has been demonstrated to vary by the sexual position adopted among partners. Guided by interdependence theory, this study examined how relational factors were differentially associated with risk taking (HIV-positive/insertive and HIV-negative/receptive) and strategic positioning (HIV-positive/receptive and HIV-negative/insertive) UAI within serodiscordant same-sex male couples. HIV-positive men and their HIV-negative partners (n _couples = 91; n _individuals = 182) simultaneously but independently completed computerized questionnaires and HIV-positive men had blood drawn for viral load. A minority of couples (30 %) engaged in risk taking and/or strategic positioning unprotected anal sex. Results of multinomial logistic regression indicated that HIV-negative partners’ levels of relationship commitment were positively associated with the odds of engaging in strategic positioning sexual behaviors. For HIV-negative partners, reports of relationship intimacy, and sexual satisfaction were negatively associated with odds of reporting risk taking behavior. In contrast, HIV-positive partners’ reported sexual satisfaction was positively associated with odds of engaging in risk taking behavior. Findings suggested that aspects of relational quality may be differentially associated with sexual decision making for same-sex male couples in serodiscordant relationships. Study findings lend support for the incorporation of discussions of HIV risk reduction strategies, enhancing communication between partners, and support for general relationship functioning in HIV care.     

High-risk behaviors among men who have sex with men in 6 US cities: baseline data from the EXPLORE Study

OBJECTIVES: We describe the prevalence of risk behaviors at baseline among men who have sex with men (MSM) who were enrolled in a randomized behavioral intervention trial conducted in 6 US cities. METHODS: Data analyses involved MSM who were negative for HIV antibodies and who reported having engaged in anal sex with 1 or more partners in the previous year. RESULTS: Among 4295 men, 48.0% and 54.9%, respectively, reported unprotected receptive and insertive anal sex in the previous 6 months. Unprotected sex was significantly more likely with 1 primary partner or multiple partners than with 1 nonprimary partner. Drug and alcohol use were significantly associated with unprotected anal sex. CONCLUSIONS: Our findings support the continued need for effective intervention strategies for MSM that address relationship status, serostatus of partners, and drug and alcohol use.     

Sexual Partnering and HIV Risk among Black Men Who Have Sex with Men: New York City

Black men who have sex with men (MSM) are disproportionately affected with HIV in the US. Limited event-specific data have been reported in Black MSM to help understand factors associated with increased risk of infection. Cross-sectional National HIV Behavioral Surveillance Study data from 503 MSM who reported ≥1 male sexual partner in the past year in New York City (NYC) were analyzed. Case-crossover analysis compared last protected and last unprotected anal intercourse (UAI). A total of 503 MSM were enrolled. Among 349 tested for HIV, 18% were positive. Black MSM (N = 117) were more likely to test HIV positive and not know their HIV-positive status than other racial/ethnic groups. Case-crossover analysis of 208 MSM found that men were more likely to engage in protected anal intercourse with a first time partner and with a partner of unknown HIV status. Although Black MSM were more likely to have Black male partners, they were not more likely to have UAI with those partners or to have a partner aged >40 years. In conclusion, HIV prevalence was high among Black MSM in NYC, as was lack of awareness of HIV-positive status. Having a sexual partner of same race/ethnicity or older age was not associated with having UAI among Black MSM.     

“Cum Play” among Gay Men

The exchange of semen, often referred to as “cum play,” has featured in gay literature and may be a unique aspect of many gay men’s sexual behavior. We investigated the prevalence of “cum play” and its context among 1153 HIV-negative and 147 HIV-positive Australian gay men in an online survey. Receptive cum play (partner ejaculating or rubbing his semen over participant’s anus, or participant using partner’s semen as lubricant) was reported by one in six HIV-negative and one quarter of HIV-positive men on the same occasion of protected anal intercourse with a casual partner (PAIC). HIV-negative men who engaged in receptive cum play during PAIC often believed that their partner was HIV seroconcordant and tended to trust that partner. They were also generally more optimistic about the likelihood of HIV transmission, and they often only used condoms at their partners’ instigation. Cum play was not uncommon and highlights the narrowness (or danger) of focusing on condom use without considering the implications of broader sexual practices and their meaning for sexual health promotion. “Safe sex” for some gay and bisexual men does not necessarily mean consistent commitment to condom use or to avoiding semen exchange. Many feel confident in their knowledge of their partner’s HIV serostatus and only use condoms with these partners at their partner’s request. Their commitment to safe sex may not necessarily be compromised by their practice of cum play, but the extent to which this could represent a risk for HIV transmission depends on the reliability of their assessment of their partners’ HIV serostatus.

Abstract：

Objective To assess the prevalence of HIV and risky sexual behaviors among university students who have sex with men(MSM)in Beijing.Methods MSM students in the universities were mainly recruited via internet.Questionnaires were self-administered to collect social demographic information and AIDS-related risky sexual behaviors.After completing the questionnaire,blood sample was collected to determine HIV infection through serological testing.X2 test and logistic regression were employed for univariate and multivariate analysis,respectively.Results A total of 157 students were recruited with mean age of 22.7±2.8 years old,12.1%of them were minorities and 77.7% were self-identified as homosexual.98.1% had engaged in anal intercourse(AI)in their lifetime and 73.9%reported that AI was common sexual behavior they often practised.In the past 6 months,58.6% had ever had unprotected anal intercourse(UAI),58.0% never used condoms during oral intercourse,and 59.2% had multiple sex partners(≥2).Nearly half of them believed that they were at low or no risk of contracting HIV and the prevalence of HIV infection was 2.5%.Data from logistic regression analysis showed that ever having had sex with a casual partner in a lifetime (OR=13.10).understanding that serving an insertive role had less risk than being receptive during the AI (OR=3.37),and ever having been to a gay bar(OR=2.49)was independently related to having multiple sex partners in the past 6 months.Conclusion Despite the extensive programs on education,behaviors regarding UAI and ever having had multiple sex partners were silll commonly seen among university MSM students.Interventions were needed to prevent HIV transmission in this population.     

Circumcision and HIV Infection among Men Who Have Sex with Men in Britain: The Insertive Sexual Role

The objective was to examine the association between circumcision status and self-reported HIV infection among men who have sex with men (MSM) in Britain who predominantly or exclusively engaged in insertive anal intercourse. In 2007–2008, a convenience sample of MSM living in Britain was recruited through websites, in sexual health clinics, bars, clubs, and other venues. Men completed an online survey which included questions on circumcision status, HIV testing, HIV status, sexual risk behavior, and sexual role for anal sex. The analysis was restricted to 1,521 white British MSM who reported unprotected anal intercourse in the previous 3 months and who said they only or mostly took the insertive role during anal sex. Of these men, 254 (16.7 %) were circumcised. Among men who had had a previous HIV test (n = 1,097), self-reported HIV seropositivity was 8.6 % for circumcised men (17/197) and 8.9 % for uncircumcised men (80/900) (unadjusted odds ratio [OR], 0.97; 95 % confidence interval [95 % CI], 0.56, 1.67). In a multivariable logistic model adjusted for known risk factors for HIV infection, there was no evidence of an association between HIV seropositivity and circumcision status (adjusted OR, 0.79; 95 % CI, 0.43, 1.44), even among the 400 MSM who engaged exclusively in insertive anal sex (adjusted OR, 0.84; 95 % CI, 0.25, 2.81). Our study provides further evidence that circumcision is unlikely to be an effective strategy for HIV prevention among MSM in Britain.

Perceived Risks and Protective Strategies Employed by Young Men Who Have Sex With Men (YMSM) When Seeking Online Sexual Partners

This study examined the perceptions of risk by young men who have sex with men (YMSM) regarding meeting sexual partners through the Internet. Fifty-four YMSM ages 18–29 who reported engaging in bareback sex (“intentional unprotected anal intercourse in high-risk contexts”) completed a structured assessment and a face-to-face interview. Participants reported using the Internet to meet sexual partners at least once per week, having had multiple sexual partners in the past 2 months (M = 10.50, SD = 9.25), and engaging in occasions of unprotected receptive (M = 5.35, SD = 6.76) and insertive (M = 5.06, SD = 10.11) anal intercourse. A third of the sample reported having had unprotected sex with a partner who was serodiscordant or of unknown serostatus. Despite the obvious HIV risks, the most commonly perceived risks included threats to physical safety and difficulties trusting a stranger. Risk reduction strategies included leaving information about partner and whereabouts with a friend, meeting in a public place, and screening partner through online chatting. Those YMSM who meet partners online may be at risk for physical violence in addition to HIV or sexually transmitted infections (STIs). Public health campaigns should increase awareness of safety concerns when meeting sexual partners online and support YMSM's self-protective actions.     

Recalled Sexual Experiences in Childhood with Older Partners: A Study of Brazilian Men Who Have Sex with Men and Male-to-Female Transgender Persons

This study assessed the prevalence of recalled childhood sexual experiences with an older partner among men who have sex with men (MSM) and/or male-to-female transgender persons recruited in Campinas, Brazil. It also analyzed associations between such recalled experiences and sexual risk behavior in adulthood. Participants recruited using respondent driven sampling completed a self-administered, computer-based questionnaire, and underwent HIV testing. For data analysis, raw scores were weighted based on participants’ reported network size. Of 575 participants (85% men and 15% transgender), 32% reported childhood sexual experiences with an older partner. Mean age at first experience was 9 years, partners being, on average, 19 years old, and mostly men. Most frequent behaviors were partners exposing their genitals, mutual fondling, child masturbating partner, child performing oral sex on partner, and child being anally penetrated. Only 29% of the participants who had had such childhood sexual experiences considered it abuse; 57% reported liking, 29% being indifferent and only 14% not liking the sexual experience at the time it happened. Transgender participants were significantly more likely to report such experiences and, compared with men, had less negative feelings about the experience at the time of the interview. No significant associations were found between sexual experiences in childhood and unprotected receptive or insertive anal intercourse in adulthood. Results highlight the importance of assessing participants’ perception of abuse, regardless of researchers’ pre-determined criteria to identify abuse. MSM and transgender people may experience childhood sexual experiences with older partners differently from other populations (e.g., heterosexuals), particularly in countries with different cultural norms concerning sexuality than those prevalent in Europe and the U.S.     

History of Childhood Sexual Abuse and Unsafe Anal Intercourse in a 6-City Study of HIV-Positive Men Who Have Sex With Men

Objectives. We assessed rates of childhood sexual abuse and its demographic and mental health correlates among HIV-positive men who reported unsafe anal intercourse with other men in the past year.Methods. We conducted a cross-sectional analysis of baseline data from 593 HIV-positive men who have sex with men enrolled in the Positive Connections intervention.Results. Childhood sexual abuse was reported by 47% of participants; 32% reported frequency as often or sometimes. Men reporting abuse were more likely to be Latino (odds ratio [OR] = 2.6; 95% confidence interval [CI] = 1.6, 4.2; P < .001) or African American (OR = 1.8; 95% CI = 1.2, 2.7; P = .005) than White. Among those who were abused, more frequent abuse was associated with more sexual contacts (for each, rate ratio [RR] = 1.3; P < .001) and unsafe anal intercourse (often, RR = 1.5; sometimes, RR = 2.0; P < .001) compared with men who were not abused.Conclusions. History of childhood sexual abuse is highly prevalent among HIV-positive men who engage in risky sexual behavior with other men and appears to be more common among men of color. Our findings suggest that abuse is associated with a significantly increased risk of sexually transmitted infections.Considerable evidence suggests that men who have sex with men (MSM) and who experienced childhood sexual abuse are at heightened risk for HIV infection and sexually transmitted infections (STIs) and associated sexual risk behaviors. Several publications have indicated that self-reported history of sexual abuse is indirectly associated with high-risk sexual behaviors among diverse samples of MSM, such as attendees at targeted events and members of support organizations for lesbian, gay, bisexual, and transgender adolescents.^1–4These reports corroborate earlier studies that found that MSM who reported childhood sexual abuse were at higher risk of becoming HIV positive and engaged in higher rates of unprotected anal intercourse. Few of these studies have focused on whether a history of childhood sexual abuse among HIV-positive MSM is associated with unprotected anal intercourse with partners who are HIV negative.^5–8 In a study of HIV-positive MSM recruited at gay venues in San Francisco and New York City, O''Leary et al. found an association between a history of childhood sexual abuse and unprotected anal intercourse with partners who were HIV negative or of unknown infection status.⁹ With little other research published on the effect of childhood sexual abuse on unsafe sexual behavior among HIV-positive MSM, the generalizability of this report is unknown.Few studies have had an adequate overall sample size to address differences in reported rates of childhood sexual abuse by race/ethnicity with precision. In a study of more than 1000 predominantly HIV-negative MSM, Doll et al. reported higher rates of childhood sexual abuse among African American and Latino than White MSM.¹⁰ Surveillance reports reveal very high rates of diagnosed and undiagnosed HIV infection among MSM of color^11,12; therefore it is critical to identify risk factors that may contribute to higher rates of unsafe sex among racial/ethnic subgroups of HIV-positive MSM.We examined the prevalence of self-reported history of childhood sexual abuse and the demographic and behavioral correlates of such abuse in a group of racially diverse HIV-positive MSM who reported anal intercourse with other men in the past year and who were enrolled in a weekend sexual health intervention to reduce unsafe sexual behavior. We hypothesized that men who reported childhood sexual abuse would also report higher rates of unprotected anal intercourse with men of HIV serodiscordant or unknown HIV infection status.
