Abstract:Using data from a multisite venue-based survey of male subjects aged 15 to 22 years, we examined racial/ethnic differences in demographics, partner type, partner type-specific condom use, drug use, and HIV prevalence in 3316 US black, multiethnic black, Latino, and white men who have sex with men (MSM). We further estimated associations of these factors with HIV infection and their influence on racial/ethnic disparities in HIV prevalence. HIV prevalences were 16% for both black and multiethnic black participants, 6.9% for Latinos, and 3.3% for whites. Paradoxically, potentially risky sex and drug-using behaviors were generally reported most frequently by whites and least frequently by blacks. In a multiple logistic regression analysis, positive associations with HIV included older age, being out of school or work, sex while on crack cocaine, and anal sex with another male regardless of reported condom use level. Differences in these factors did not explain the racial/ethnic disparities in HIV prevalence, with both groups of blacks experiencing more than 9 times and Latinos experiencing approximately twice the fully adjusted odds of infection compared with whites. Understanding racial/ethnic disparities in HIV risk requires information beyond the traditional risk behavior and partnership type distinctions. Prevention programs should address risks in steady partnerships, target young men before sexual initiation with male partners, and tailor interventions to men of color and of lower socioeconomic status.

OBJECTIVES We examined differences in HIV seroprevalence and the likely timing of HIV infection by birth region. METHODS We analyzed unlinked HIV antibody data on 61 120 specimens from 7 public health centers in Los Angeles County from 1993 to 1999. RESULTS Most (87%) immigrant clients were Central American/Mexican-born. HIV prevalence was similar for US- and foreign-born clients (1.8% [95% confidence interval (CI) = 1.7%, 1.9%] and 1.6% [95% CI = 1.5%, 1.8%], respectively). Seroprevalence was high among sub-Saharan African females and low among Asian/Pacific Islander males and females. For HIV-positive immigrants, the average age at and time since immigration were 20.6 years and 12.3 years, respectively. CONCLUSIONS The relatively young age at arrival and long time since arrival for HIV-positive foreign-born clients suggest that most were infected after immigration.

Disproportionately high HIV/AIDS rates and frequent non-gay identification (NGI) among African American men who have sex with men or with both men and women (MSM/W) highlight the importance of understanding how HIV-positive African American MSM/W perceive safer sex, experience living with HIV, and decide to disclose their HIV status. Thirty predominately seropositive and non-gay identifying African American MSM/W in Los Angeles participated in three semi-structured focus group interviews, and a constant comparison method was used to analyze responses regarding condom use, sexual activity after an HIV diagnosis, and HIV serostatus disclosure. Condom use themes included its protective role against disease and pregnancy, acceptability concerns pertaining to aesthetic factors and effectiveness, and situational influences such as exchange sex, substance use, and suspicions from female partners. Themes regarding the impact of HIV on sexual activity included rejection, decreased partner seeking, and isolation. Serostatus disclosure themes included disclosure to selective partners and personal responsibility. Comprehensive HIV risk-reduction strategies that build social support networks, condom self-efficacy, communication skills, and a sense of collective responsibility among NGI African American MSM/W while addressing HIV stigma in the African American community as a whole are suggested.

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.

Self-reported HIV-negative black and Latino MSM who engaged in serosorting or strategic positioning were less likely to have unrecognized HIV infection than men who engaged in unprotected anal intercourse without using these risk-reduction strategies.

Objective:To identify demographic, behavioral, and psychological variables associated with being HIV positive unaware among black and Latino men who have sex with men (MSM). Methods:Participants recruited in 3 cities completed a computer-assisted interview and were tested for HIV infection (OraSure Technologies, Bethlehem, PA). HIV-positive unaware MSM were compared with MSM who tested HIV negative in bivariate and multivariate analyses. Results:Of 1208 MSM (597 black and 611 Latino), 11% were HIV-positive unaware (18% black; 5% Latino). In multivariate analysis of the Latino MSM, being HIV-positive unaware was associated with nongay identity, high perceived risk of currently being HIV positive, and belief that sex with other Latino men reduces HIV transmission risk. Among black MSM, being HIV-positive unaware was associated with gay identity, moderately higher income, having health insurance, sexuality disclosure to a current health care provider, fewer than 3 lifetime HIV tests, high perceived risk of testing HIV positive, and belief that sex with other black men reduces HIV transmission risk. Conclusions:HIV prevention efforts should address misperceptions among those black and Latino MSM who believe that assortative (ie, intraracial) sexual mixing reduces risk of HIV infection. Our findings also revealed missed opportunities to diagnose black MSM with HIV infection who were already engaged in care and had disclosed their sexuality to their health care provider. Clinicians should offer HIV testing to all MSM, particularly black MSM, who disclose engaging in recent sex with other men to facilitate earlier diagnosis of HIV infection and reduce transmission risk to sexual partners.

Objectives The authors examine whether young black and Latino men who have sex with men (MSM) who have older sex partners are more likely than those who do not have older sex partners to have unrecognised HIV infection. The authors examine whether the association stems from (1) increased sexual risk behaviour with male partners of any age, (2) heightened risk of being exposed to HIV infection by older partners or (3) a combination of these two factors. Methods The analytical sample consisted of 723 black and Latino MSM, aged 18–35 years, who were HIV negative or of unknown serostatus at study entry. Participants completed a self-administered questionnaire and were tested for HIV infection. Men who reported having a male sex partner who was at least 4 years older than themselves were compared with those who did not. Outcomes included unprotected receptive anal intercourse (URAI) with male partners of any age (past 3 months) and having unrecognised HIV infection. Results Men with older partners reported a higher prevalence of URAI (AOR=1.50, 95% CI 1.02 to 2.21). A second model found that men with older partners had increased odds of having unrecognised HIV infection (AOR=2.51, 95% CI 1.18 to 5.34) after controlling for the number of URAI partners of any age, which remained an independent predictor. Conclusions Young black and Latino MSM who had older male sex partners were at increased risk of having unrecognised HIV infection. This heightened risk was associated with sexual risk behaviour with partners of any age as well as possible increased exposure to HIV infection from older partners.

Unrecognized HIV infections, where the individual is unaware of his or her HIV serostatus, may play the most important role in the continued spread of HIV. Using venue-level data from the National HIV Behavioral Surveillance System, we conducted preliminary bivariate analyses to identify variables associated with unrecognized HIV infection and subsequently entered those variables into multiple logistic regression models to then characterize unrecognized HIV infections in Los Angeles and San Francisco. In Los Angeles, public sex environments have the highest likelihood of having men who have sex with men (MSM) with unrecognized HIV infection (adjusted odds ratio (AOR) 3.2, 95% confidence interval (CI) = 1.3-7.9). For San Francisco, MSM with unrecognized HIV infection are most likely found in adult bookstores (AOR = 8.0, 95% CI = 2.8-39). We identified opportunities to promote HIV testing through specific locations where unrecognized infections among MSM are found in highest concentrations.

This article examines the sociodemographic/behavioral variables associated with low peer support of condom use and the relation between low peer support of condom use and unprotected anal sex for Black and Latino MSM in cities heavily impacted by the HIV/AIDS epidemic. Our findings indicate that perceived low peer support of condom use is associated with increased odds of recent unprotected anal intercourse (UAI) among Black and Latino MSM, regardless of male partner type. Although many participants reported having high peer support of condom use, this analysis highlights a considerable subgroup of Black and Latino MSM, 21% and 30%, respectively, who report low peer support of condoms. Given the prevalence of low peer support of condom use and its association with UAI in these highly impacted MSM populations, we recommend future intervention work that draws upon Black and Latino MSMs peer and social network members to reduce HIV risk behaviors.

Background: We aimed to describe the use of voluntary HIV counseling and testing services, risk behaviors, and risk factors for unprotected anal sex (UAS) among men who have sex with men (MSM) who attended a bathhouse in Los Angeles during 2001–2002. Methods: Using 2 cross-sectional study samples, we compared (in order below) 458 of 640 MSM who used voluntary HIV counseling and testing in the bathhouse with 398 MSM surveyed upon exit. Within each group, logistic regression identified factors associated with UAS at their most recent bathhouse visit. Results: Of 640 MSM, 71 (11%) tested HIV-positive for the first time. Of the 50 HIV-positive MSM who completed a survey, 50% tested because of the convenient services. Similar proportions of MSM in both survey samples reported UAS (7%–8%) during their recent bathhouse visit. Risk factors associated with UAS in both survey samples were UAS with men outside the bathhouse and greater numbers of partners within the bathhouse. Conclusions: Comprehensive prevention services provided within bathhouses may reduce undiagnosed HIV infections among MSM, and targeting HIV prevention at the bathhouse may reduce risks with partners both inside and outside the bathhouse.
