Gay and bisexual men are often treated as a homogenous group; however, there may be important differences between them. In addition, behaviorally bisexual men are a potential source of HIV infection for heterosexual women. In this study, we compared 97 men who have sex with men only (MSM) to 175 men who have sex with men and women (MSMW). We also compared the 175 MSMW to 772 men who have sex with women only (MSW). Bivariate and multiple logistic regression analyses were performed to assess correlates of MSMW risk behaviors with men and with women as well as whether MSMW, compared with MSW, engaged in more risky behaviors with women. Compared with MSM, MSMW were less likely to be HIV-positive or to engage in unprotected receptive anal intercourse. In contrast, MSMW were more likely than MSW to be HIV-positive and to engage in anal intercourse with their female partners; however, rates of unprotected anal intercourse were similar. The study findings suggest that there may be important differences in HIV risk behaviors and HIV prevalence between MSM and MSMW as well as between MSMW and MSW.  相似文献

Male-to-female transgender persons are thought to be “vectors” for HIV/STI transmission, yet little quantitative information exists about the risk behavior of their male sexual partners who may serve as a “bridge” for HIV transmission into the general population. As part of an online survey examining the sexual risk behavior of Latino men who have sex with men (N = 1,026), we identified 44 (4%) participants who reported having had sex with a transgender partner. Compared with a randomly selected sub-sample of 200 men who did not report sex with a transgender person, sexual partners of transgender persons were almost three times more likely to have had unprotected sexual intercourse in the last three months. In addition, men who had sex with transgender persons were more likely to be HIV-positive; married, separated, or divorced; identify as bisexual or straight; have sex with women; and live in rural or small town communities. Regression analysis revealed that community size, sexual compulsivity, and having had a transgender partner were independent predictors of unprotected sex. Among Latino men who have sex with men, men with a history of sex with a transgender person appear more likely to be sexually compulsive and at greater risk for HIV and other sexually transmitted infections. These men may, therefore, also serve as a “bridge” for HIV transmission to (as opposed to from) the transgender population.  相似文献

CONTEXT: HIV-positive men and women may have fertility desires and may intend to have children. The extent of these desires and intentions and how they may vary by individuals' social and demographic characteristics and health factors is not well understood. METHODS: Interviews were conducted from September through December 1998 with 1,421 HIV-infected adults who were part of the HIV Cost and Services Utilization Study, a nationally representative probability sample of 2,864 HIV-infected adults who were receiving medical care within the contiguous United States in early 1996. RESULTS: Overall, 28-29% of HIV-infected men and women receiving medical care in the United States desire children in the future. Among those desiring children, 69% of women and 59% of men actually expect to have one or more children in the future. The proportion of HIV-infected women desiring a child in the future is somewhat lower than the overall proportion of U.S. women who desire a child. The fertility desires of HIV-infected individuals do not always agree with those of their partners: As many as 20% of HIV-positive men who desire children have a partner who does not Generally, HIV-positive individuals who desire children are younger, have fewer children and report higher ratings of their physical functioning or overall health than their counterparts who do not desire children, yet desire for future childbearing is not related to measures of HIV progression. HIV-positive individuals who expect children are generally younger and less likely to be married than those who do not. Multivariate analyses indicate that black HIlV-positive individuals are more likely to expect children in the future than are others. While HIV-positive women who already have children are significantly less likely than others both to desire and to expect more births, partner's HIV status has mixed effects: Women whose partner's HIVstatus is known are significantly less likely to desire children but are significantly more likely to expect children in the future than are women whose partner's HIV status is unknown. Moreover, personal health status significantly affects women's desire for children in the future but not men's, while health status more strongly influences men's expectations to have children. CONCLUSIONS: The fact that many HIV-infected adults desire and expect to have children has important implications for the prevention of vertical and heterosexual transmission of HIV, the need for counseling to facilitate informed decision-making about childbearing and childrearing, and the future demand for social services for children born to infected parents.  相似文献

This study examined demographic characteristics, sexual risk behaviors, sexual beliefs, and substance use patterns in HIV-positive, methamphetamine-using men who have sex with both men and women (MSMW) (n = 50) as compared to men who have sex with men only (MSM) (n = 150). Separate logistic regressions were conducted to predict group membership. In the final model, of 12 variables, eight were independently associated with group membership. Factors independently associated with MSMW were acquiring HIV through injection drug use, being an injection drug user, using hallucinogens, using crack, being less likely to have sex at a bathhouse, being less likely to be the receptive partner when high on methamphetamine, having greater intentions to use condoms for oral sex, and having more negative attitudes about HIV disclosure. These results suggest that, among HIV-positive methamphetamine users, MSMW differ significantly from MSM in terms of their HIV risk behaviors. Studies of gay men and HIV often also include bisexual men, grouping them all together as MSM, which may obscure important differences between MSMW and MSM. It is important that future studies consider MSM and MSMW separately in order to expand our knowledge about differential HIV prevention needs for both groups. This study showed that there were important differences in primary and secondary prevention needs of MSM and MSMW. These findings have implications for both primary and secondary HIV prevention among these high-risk populations.  相似文献

OBJECTIVE: In order to generate a generalizable estimate regarding risk for STI and HIV acquisition in men who have sex with men (MSM) who seek partners on the internet, we examined the sexual practices of MSM who seek partners on the internet compared to MSM who do not, using a community-based sample of MSM from British Columbia. METHODS: 'Sex Now', a questionnaire that was developed to examine trends in sexual behaviour in gay men, was offered to men attending Gay Pride events throughout the province of British Columbia, Canada between May and August 2004. Logistic regression analysis was used to model the association between seeking sexual partners online and other variables of interest, using odds ratio as the measure of association. RESULTS: Of the 2,312 MSM who completed the survey, 766 (33.1%) had used the internet to find a partner in the past year. In logistic regression analyses, MSM who found partners on the internet were more likely to have had more than 10 sexual partners in the past year (overall, insertive and receptive), and to engage in sexual activities in public venues. They were also more likely to agree with the statement "I think most guys in relationships have condom-free sex." MSM who sought partners on the net were more likely to be from specific geographic regions, including non-urban regions. Demographic characteristics, HIV status, and use of drugs were not significantly different between men who found partners on the internet and those who did not in multivariable modeling. DISCUSSION: MSM who sought to meet partners online had significantly more sexual partners, were more likely to be from specific geographic regions of the province and to have participated in seeking sexual partners in venues known to be associated with HIV and STI acquisition. This study confirms from a community-based sample of MSM that programming for prevention and treatment of HIV and STI need to be available and offered in the cyber setting, to ensure effective messaging and interventions reach this population.  相似文献

The House Ball Community (HBC) is an understudied network of African American men who have sex with men and transgender women, who join family-like houses that compete in elaborate balls in cities across the United States. From 2011 to 2012, we surveyed 274 recent attendees of balls in the San Francisco Bay Area, focusing on social networks, social support, and HIV-related behaviours. Participants with a high percentage of alters who were supportive of HIV testing were significantly more likely to have tested in the past six months (p?=?.02), and less likely to have engaged in unprotected anal intercourse (UAI) in the past three months (p?=?.003). Multivariate regression analyses of social network characteristics, and social support, revealed that testing in the past six months was significantly associated with social support for safer sex, instrumental social support, and age. Similarly, UAI in the past three months was significantly associated with social support for safer sex, homophily based on sexual identity and HIV status. HIV-related social support provided through the HBC networks was correlated with recent HIV testing and reduced UAI. Approaches utilising networks within alternative kinship systems, may increase HIV-related social support and improve HIV-related outcomes.  相似文献

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.  相似文献

We use data from an anonymous self-administered 1991 survey of military personnel in northern Thailand to estimate overall levels of and socio-demographic differentials in same-sex sexual behaviour in this population. Additionally, we examine the relationship between sexual experience with another male and a variety of outcomes relevant to HIV prevention and policy. Overall, 16.3 per cent of the sexually active soldiers report ever having had anal or oral sex with other males. Same-sex sexual behaviour in this sample is positively associated with several indicators of higher socio-economic status. All of the men who report having had sex with other men report having had vaginal intercourse with females as well. Comparison of our estimate of same-sex sexual behaviour with those obtained from two similar samples drawn in 1991 suggests that the lower estimates observed in the other two studies are largely due to differences in data collection methods. Regarding the HIV/AIDS-related outcomes we examined, men who have had sex with other men are significantly more likely than those who have not to have ever injected drugs, to personally know someone with HIV/AIDS, to have had sex with a female prostitute in the last six months, and to have had a sexually transmitted disease in the last six months. In this sample, men who have had sex with other men are also less knowledgeable about HIV/AIDS than are men who have not. These results are discussed in terms of their implications for HIV-prevention policy in Thailand.  相似文献

Objective: To assess the psychological and behavioral characteristics of gay and bisexual men who intend to use antiretroviral post-exposure prophylaxis (PEP) to prevent HIV infection.Methods: Gay and bisexual men who had not tested HIV seropositive and were not in long-term exclusive sexual relationships (n = 327) completed anonymous surveys consisting of demographic characteristics, gay community acculturation, experience with and attitudes toward PEP, substance use, and sexual behavior in the past 6 months.Setting: A large annual Gay Pride festival in Atlanta, Georgia.Results: There were 8 (3%) men who had already used PEP and 85 (26%) who planned to use PEP to prevent themselves from becoming HIV infected. Compared to the 242 (74%) men who did not indicate plans to use PEP, those planning to use PEP were younger, less well educated, more likely to have used illicit substances in the past 6 months, and were more likely to have a history of injection drug use. Men intending to use PEP were also more likely to have practiced unprotected anal and oral intercourse as the receptive partner and were more likely to have multiple anal intercourse partners with whom they were receptive.Conclusions: Gay and bisexual men are generally supportive of the immediate use of PEP and a significant number of men are planning to use PEP, particularly less educated men who use multiple substances and practice the highest-risk sexual behaviors. Concurrent behavioral interventions must, therefore, be considered critical in the advancement of PEP.  相似文献

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.  相似文献

OBJECTIVES. This study compares characteristics, behaviors, and human immunodeficiency virus (HIV) infection in women who reported same-sex contact and women who had sex only with men. METHODS. Participants were patients attending a New York City sexually transmitted disease clinic. Structured questionnaires were administered by interviewers. RESULTS. Overall, 9% (135/1518) of women reported same-sex contact; among these, 93% also reported contact with men. Women reporting same-sex contact were more likely than exclusively heterosexual women to be HIV seropositive (17% vs 11%; odds ratio [OR] = 1.7, 95% confidence interval [CI] = 1.0, 2.6), to exchange sex for money/drugs (48% vs 12%, OR = 6.7, 95% CI = 4.6, 9.8), to inject drugs (31% vs 7%, OR = 6.3, 95% CI = 4.1, 9.5), and to use crack cocaine (37% vs 15%, OR = 3.3, 95% CI = 2.2, 4.8). HIV in women reporting same-sex contact was associated with history of syphilis (OR = 8.8), sex for crack (OR = 5.7), and injection drug use (OR = 4.5). CONCLUSIONS. In this study, women who reported same-sex contact were predominantly bisexual. They had more HIV risk behaviors and were more often HIV seropositive than women who had sex only with men. Among these bisexual women, heterosexual contact and injection drug use were the most likely sources of HIV. There was no evidence of female-to-female transmission.  相似文献

OBJECTIVE: To examine HIV risks among South African men who report having been sexually assaultive. METHODS: Men (N = 412) in Cape Town completed anonymous surveys. RESULTS: Twenty-three percent reported a history of sexual assault. Men who had been sexually assaultive were younger, reported more sex partners, were more likely to have a history of genital ulcers, and more likely to have exchanged money for sex. Sexually assaultive men were also more likely to endorse rape myths. CONCLUSIONS: Interventions that target men as the agents of change in reducing sexual assaults and HIV transmission are urgently needed.  相似文献

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.  相似文献

HIV transmission: Women's risk from bisexual men.   总被引:3,自引:2,他引:1       下载免费PDF全文
The purpose of this study was to characterize the risk of human immunodeficiency virus (HIV) infection for men who have sex with men and to identify the risk such men pose to their female sex partners. The subjects were 5480 men who were tested for HIV between January 1987 and December 1991 and who reported having had sex with a man since 1977. Men who identified themselves as bisexual or straight were more likely to use injection drugs, had a substantial HIV seroprevalence, and reported many more female partners than men who identified themselves as gay. Men who identify themselves as bisexual pose the greatest risk to their female partners.  相似文献

HIV/AIDS has disproportionately affected Latino communities. The majority of research addressing HIV risk behaviors within this population has focused on women. However, men who have sex with women (MSW) are a population increasingly becoming infected with HIV and heterosexual contact is the primary source of HIV transmission among Latinos diagnosed with AIDS. It has been assumed that because men are likely to control condom use, relationship factors are less likely to influence safer sex behavior among men. However, because condom use is an interdependent behavior, understanding factors that predict safer sex behavior among MSW is critical. This study examined the influence of multiple factors on condom use behavior in a community-based sample of young Latino men. Data from 191 Latino men who completed baseline interviews for an intervention were analyzed to examine the association of background, intrapersonal and relationship factors with intentions to use condoms and condom use in the past three months. Findings from multivariate analyses indicated that more positive attitudes toward condoms, stronger partner condom norms and greater participation in decision-making about condom use were significantly associated with both condom use and condom use intentions. Additionally, men reporting lower expectations of negative partner reactions to condom requests were more likely to use condoms, and condom use intentions were higher among men reporting more health protective communication in the relationship. Findings suggest that interventions to prevent HIV need to include men as well as women and address the role of relationship factors and dynamics in safer sex practices.Harvey is with the Department of Public Health, Oregon State University, Corvallis, OR, USA; Henderson is with the Bixby Center for Reproductive Health Research & Policy, University of California, San Francisco, CA, USA.  相似文献

We assessed whether economic, legal, and social hardships were associated with human immunodeficiency virus (HIV) risk among a sample of Black men who have sex with men (MSM) and whether associations were moderated by city of residence. The study analyzed baseline and follow-up data from HIV Prevention Trials Network 061 (N = 1553). Binary logistic regression assessed associations between hardships and HIV risk indicators. Multivariate regressions were used to test if city of residence had a moderating effect for hardships and HIV risks. Adjusted analyses showed that Black MSM with recent job loss were more likely to engage in condomless insertive anal intercourse (adjusted odds ratios (AOR) = 1.37, 95 % CI 1.01–1.87) and that those with recent financial crisis were more likely to have had two or more male sexual partners in the past 6 months (AOR = 1.65; 95 % CI 1.18–2.29). Black MSM with recent convictions were more likely to have a sexually transmitted infection at 6 months (AOR = 3.97; 95 % CI 1.58–9.94), while those who were unstably housed were more likely to have a sexually transmitted infection at 12 months (AOR = 1.71; 95 %CI 1.02 = 2.86). There were no city of residence and hardship interaction effects on HIV risks. Hardships are important factors that influence HIV risk for Black MSM. Integrating strategies that address structural factors that influence HIV risk may enhance HIV prevention interventions implementation efforts.  相似文献

Sex trade behavior is fairly common among homeless adults and may contribute to higher rates of HIV/AIDS in this population. This study provides a detailed examination of the sex trade-related attitudes and behaviors of homeless men by: (1) determining the prevalence of sex trade-related behaviors, including sex with female sex workers (FSWs); (2) identifying risk factors for having sex with FSWs; and (3) comparing men’s relationships with FSWs and non-FSWs in terms of relationship qualities and HIV-related risk behaviors, such as condom use. Structured interviews were conducted with a probability sample of 305 heterosexually active homeless men recruited from meal lines in Los Angeles. Recent sex with a FSW was reported by 26 % of men, and more likely among those who were older, used crack cocaine, had more sex partners, believed that sometimes men just need to have sex no matter what, and were embedded in networks that were denser and where risky sex was more normative. Compared to non-FSW partners, men with FSW partners felt less emotionally close to them, were more likely to believe the partner had never been tested for HIV, and were more likely to have sex with them under the influence of drugs or alcohol; however, they were not more likely to talk about using condoms or to use condoms with FSWs. Whether the relationship was considered “serious” was a stronger correlate of condom use than whether the partner was a FSW. Implications of these findings for HIV prevention efforts among homeless adults are discussed.  相似文献

A study by Canadian researchers found that young gay men with a history of sexual abuse were twice as likely to have unprotected anal intercourse as gay men who had not been abused. Nearly one third of the 287 gay men in the study sample in Vancouver reported being coerced into having sex. Sexual abuse survivors were more apt to experience depression and self-loathing attitudes, and were more likely than other gay men to use cocaine, tobacco and nitrite inhalants. The findings suggest a vulnerability among male survivors of sexual abuse toward behaviors that place them at risk for HIV infection, and suggest that sexual abuse counseling should be integrated into HIV prevention efforts. Researchers of the study suggest that lingering effects of sexual abuse appear to be a more potent risk factor than the use of either alcohol or drugs.  相似文献

Data from a nationally representative longitudinal survey show that seven percent of young males aged 20-27 in 1984 had fathered a child while they were teenagers, more than three-quarters of them nonmaritally. One-third of those who were responsible for a nonmarital conception married within 12 months of conception, and half of all of the young men lived with their child shortly after the child's birth. Overall, young black men were more likely to have been responsible for a nonmarital first birth than were males of other racial backgrounds, and only 15 percent of black teenagers lived with their first child, compared with 48 percent of Hispanics, 58 percent of disadvantaged whites and 77 percent of nondisadvantaged whites. Multivariate analyses indicated that only black or Hispanic youths and those who fathered a child at age 16 or younger were significantly less likely to have lived with their first child; those who were raised Catholic were more likely to have done so. Further analyses revealed that living in a rural area, being relatively older at the child's birth, having been raised Catholic and having lived with both parents at age 14 were associated with an above average probability that white teenage fathers would live with their child, at least initially. However, none of the variables in the model were significant for blacks. Teenage fathers, regardless of their marital status at conception or age at first birth, were much more likely to have been high school dropouts than were other male teenagers. Those with a maritally conceived child had a particularly high drop-out rate--almost 62 percent. Among teenage fathers responsible for a nonmaritally conceived first birth that occurred before they received their diploma or GED certificate or received their diploma or GED certificate or they left school for the last time, those living with their partner shortly after the child's birth were less likely to have completed high school by 1984 than were those not living with their child. However, a multivariate analysis revealed that a teenage father's living with his child shortly after birth was not significantly related to his completion of high school, while being black was positively associated.(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献
