Black men who have sex with men (MSM) are at increased risk for HIV infection in the United States compared to other MSM. The aim of this study was to investigate Black MSM's sexual mixing patterns and partner characteristics in relation to sexual risk taking, as a possible explanation for this observed increase in HIV incidence. Between January and July 2008, 197 Black MSM were recruited via modified respondent-driven sampling and completed optional pretest and post-test HIV serological testing, counseling, and a demographic, behavioral, and psychosocial assessment battery. Bivariate and multivariable logistic regression procedures were used to examine predictors of risky sex across partner types. Overall, 18% of the sample was HIV-infected; 50% reported unprotected intercourse with men, 30% with women, and 5% with transgender partners. Fifty-three percent identified as bisexual or straight, although all reported oral or anal sex with another man in the prior 12 months. Significant predictors of engaging in at least one episode of: (1) serodiscordant unprotected anal sex (UAS) with a male partner in the past 12 months: individuals at risk for social isolation (AOR = 4.23; p = 0.03), those with unstable housing (AOR = 4.19; p = 0.03), and those who used poppers at least weekly during sex (AOR = 5.90; p = 0.05); (2) UAS and/or unprotected vaginal intercourse with a female partner in the past 12 months: those with unstable housing (AOR = 4.85; p = 0.04), those who used cocaine at least weekly during sex (AOR = 16.78; p = 0.006), being HIV-infected (AOR = 0.07; p = 0.02), and feeling social norms favor condom use (AOR = 0.60; p = 0.05); (3) UAS with the participants' most recent nonmain male sex partner: use of alcohol and drugs during last sex by participant (AOR = 4.04; p = 0.01), having sex with a Hispanic/Latino male (AOR = 2.71; p = 0.04) or a Black male (AOR = 0.50; p = 0.05) compared to a White male, and lower education (AOR = 1.31; p = 0.02). Findings suggest that sexual risk behaviors of Black MSM differ across partner type and by the characteristics of their sexual networks and that this subpopulation of MSM are at high risk for HIV acquisition and transmission. Effective prevention strategies need to address the distinct sexual and behavioral risk patterns presented by different sexual partnerships reported by Black MSM.

The inpatient medical service may be an important location to identify undiagnosed hepatitis C virus (HCV) infection. We conducted a cross-sectional HCV prevalence study in consecutive patients aged 18-65 admitted in a three-month period to two urban hospitals' general internal medicine and trauma services. Patient sera were anonymously screened for anti-HCV antibody with an enzyme-linked immunoassay and, when anti-HCV positive (+), for HIV. Health system records were examined for prior HCV testing or diagnosis or an HIV diagnosis then linked anonymously to test results. Multivariate logistic regression was used to examine associations of patient and health care factors with unknown HCV+ status. Of 786 unique patients tested (60.3% of all admitted patients), 62 (7.9%) were HCV+ without a prior HCV+ test or diagnosis while 61 patients (7.8%) tested HCV+ but had prior HCV+ test or diagnosis. Of 62 patients with unknown HCV+, 6 (9.7%) were HIV+ but only 3 had a prior HIV diagnosis; of 61 patients with known HCV+, all 9 (14.8%) HIV+ had been diagnosed. Among the 640 patients with prior unknown HCV status, an HCV+ test was strongly associated with age: 50-65 (adjusted odds ratio [AOR] 5.44, CI 2.20-13.48) and age 36-49 (AOR 4.65, CI 1.91-11.32) versus. 18-35. In this anonymous study, we could not obtain HCV risk factor data but the positive and negative predictive values of HCV testing all inpatients with an unknown HCV status were 99.3% and 99.0%, respectively. In similar urban general medicine and trauma services, broader efforts to test for HCV in inpatients aged 36-65 may be warranted.

Tijuana is situated on the Mexico-USA border adjacent to San Diego, CA, on a major drug trafficking route. Increased methamphetamine trafficking in recent years has created a local consumption market. We examined factors associated with methamphetamine use and routes of administration by gender among injection drug users (IDUs). From 2006-2007, IDUs > or =18 years old in Tijuana were recruited using respondent-driven sampling, interviewed, and tested for HIV, syphilis, and TB. Logistic regression was used to assess associations with methamphetamine use (past 6 months), stratified by gender. Among 1,056 participants, methamphetamine use was more commonly reported among females compared to males (80% vs. 68%, p < 0.01), particularly, methamphetamine smoking (57% vs. 34%; p < 0.01). Among females (N = 158), being aged >35 years (AOR, 0.2; 95% CI, 0.1-0.6) was associated with methamphetamine use. Among males (N = 898), being aged >35 years (AOR, 0.5; 95% CI, 0.3-0.6), homeless (AOR, 1.4 (0.9-2.2)), and ever reporting sex with another male (MSM; AOR, 1.9; 95% CI, 1.4-2.7) were associated with methamphetamine use. Among males, a history of MSM was associated with injection, while sex trade and >2 casual sex partners were associated with multiple routes of administration. HIV was higher among both males and females reporting injection as the only route of methamphetamine administration. Methamphetamine use is highly prevalent among IDUs in Tijuana, especially among females. Routes of administration differed by gender and subgroup which has important implications for tailoring harm reduction interventions and drug abuse treatment.

Men who have sex with men (MSM) continue to bear a disproportionate HIV and sexually transmitted disease (STD) burden. The current study examined the frequency and associations of sexual risk reduction behaviors among a sample of MSM in the greater Boston, Massachusetts area. One hundred eighty-nine MSM completed a one-time behavioral and psychosocial assessment between March 2006 and May 2007. Logistic regression procedures examined the association of demographic, psychosocial, and behavioral factors with risk reduction practices. Twenty percent of the sample reported rimming, mutual masturbation, digital penetration, using sex toys, or 100% condom use as a means to reduce their risk of acquiring or transmitting HIV in the prior 12 months. In bivariate analyses, risk reducers were more likely to disclose their MSM status (i.e., be "out"; odds ratio [OR] = 3.64; p < 0.05), and report oral sex with a condom in the prior 12 months (OR = 4.85; p < 0.01). They were less likely to report: depression (Center for Epidemiologic Studies Depression Scale [CES-D] score 16+; OR = 0.48; p < 0.05), a history of one or more sexually transmitted diseases (STDs; OR = 0.40; p < 0.05), and meeting sexual partners at public cruising areas (OR = 0.32; p < 0.01). In a multivariable model, risk reducers were less likely to report: alcohol use during sex (adjusted odds ratio [AOR] = 0.33; p < 0.05), depression (CESD score 16+; AOR = 0.32; p < 0.05), or meeting sexual partners at public cruising areas (AOR = 0.30; p < 0.05), or via the Internet (AOR = 0.12; p < 0.05) in the previous 12 months. Identifying and understanding such factors associated with risk reduction behaviors may be important to consider in designing effective prevention interventions to promote sexual health for MSM.

The purpose of the study was to determine the potential contribution of bisexual men to the spread of HIV in Los Angeles. We compare the characteristics and behaviors of men who have sex with men and women (MSMW) to men who have sex with only women (MSW) and men who have sex with only men (MSM) in Los Angeles. Men (N = 1,125) who participated in one of the two waves of data collection from 2005 to 2007 at the Los Angeles site for NIDA's Sexual Acquisition and Transmission of HIV-Cooperative Agreement Program were recruited using Respondent Driven Sampling. Participants completed Audio Computer Assisted Self Interviews and received oral HIV rapid testing with confirmatory blood test by Western Blot and provided urine specimens for detection of recent powder cocaine, crack cocaine, methamphetamine, or heroin use. MSM, MSW, or MSMW were defined by the gender of whom they reported sex with in the past 6 months. Chi-square tests and ANOVAs were used to test independence between these groups and demographic characteristics, substance use, and sexual behaviors. We fit generalized linear random intercept models to predict sexual risk behaviors at the partner level. Men were mostly of low income, unemployed, and minority, with many being homeless; 66% had been to jail or prison, 29% had ever injected drugs, and 25% had used methamphetamine in the past 30 days. The sample had high HIV prevalence: 12% of MSMW, 65% of MSM, and 4% of MSW. MSMW were behaviorally between MSW and MSM, except that more MSMW practiced sex for trade (both receiving and giving), and more MSMW had partners who are drug users than MSW. Generalized linear random intercept models included a partner-level predictor with four partner groups: MSM, MSMW-male partners, MSMW-female partners, and MSW. The following were significantly associated with unprotected anal intercourse (UAI): MSW (AOR 0.15, 95% CI 0.08, 0.27), MSMW-female partners (AOR 0.4, 95% CI 0.27, 0.61), HIV-positive partners (AOR 2.03, 95% CI 1.31, 3.13), and being homeless (AOR 1.37, 95% CI 1.01, 1.86). The factors associated with giving money or drugs for sex were MSMW-female partners (AOR 1.70, 95% CI 1.09, 2.65), unknown HIV status partners (AOR 1.72, 95% CI 1.29, 2.30), being older (AOR 1.02, 95% CI 1.00, 1.04), history of incarceration (AOR 1.64, 95% CI 1.17, 2.29), and being homeless (AOR 1.73, 95% CI 1.27, 2.36). The following were associated with receiving money or drugs for sex: MSW (AOR 0.53, 95% CI 0.32, 0.89), African American (AOR 2.42, 95% CI 1.56, 3.76), Hispanic (AOR 1.85, 95% CI 1.12, 3.05), history of incarceration (AOR 1.44, 95% CI 1.04, 2.01), history of injecting drugs (AOR 1.57, 95% CI 1.13, 2.19), and had been recently homeless (AOR 2.14, 95% CI 1.57, 2.94). While overall HIV-positive MSM had more UAI with partners of any HIV status than MSMW with either partner gender, among HIV-positive MSMW, more had UAI with HIV-negative and HIV status unknown female partners than male partners. Findings highlight the interconnectedness of sexual and drug networks in this sample of men-as most have partners who use drugs and they use drugs themselves. We find a concentration of risk that occurs particularly among impoverished minorities-where many men use drugs, trade sex, and have sex with either gender. Findings also suggest an embedded core group of drug-using MSMW who may not so much contribute to spreading the HIV epidemic to the general population, but driven by their pressing need for drugs and money, concentrate the epidemic among men and women like themselves who have few resources.

The secondary effect of a national, targeted, outreach initiative in reducing sexual risk behavior among newly diagnosed persons living with HIV/AIDS (PLWHA) was examined in the present study. The findings propose an optimal number of outreach program contacts associated with a change in sexual risk behavior. The primary goal of the initiative was to implement and evaluate strategies to engage and retain underserved populations (PLWHA) in HIV primary medical care. Participants from 10 sites nationwide were enrolled in outreach interventions from 2004 to 2005 that were designed to engage and retain hard-to-reach PLWH in care. The study population in the subanalysis performed was predominantly male, people of color, sexual minorities; mean age of 32, and 31% reported no visits to an HIV health provider since testing positive. The study design was prospective and nonrandomized; 116 newly diagnosed individuals reported on unprotected sex at baseline, 6-, and 12-month interviews. The proportion of individuals reporting unprotected sex postintervention was reduced significantly compared to baseline. Postbaseline, individuals were 80% less likely to report unprotected sex. Additionally, individuals with 1-3 program contacts per month were 80 times less likely to report risky sexual behavior compared to those with 2 or less contacts (adjusted odds ratio [AOR] = 0.20). Substantial risk exists for secondary HIV transmission; this study shows the promise of a supplemental intervention to ensure access to HIV care, retention in care, and risk reduction for positives.

Undiagnosed HIV infection remains a significant public health problem. To address this, the Centers for Disease Control and Prevention revised testing recommendations, calling for routine opt-out HIV screening among adults in health care settings. However, these recommendations have not been widely implemented in primary care settings. We examined acceptability of opt-out HIV testing in an urban community health center and factors associated with accepting testing. From July 2007 to March 2008, physicians or a designated HIV tester approached patients presenting for primary care visits during 52 clinical sessions at an urban community health center. Patients were told they "would be tested for HIV unless they declined testing." Enzyme-linked immunosorbent assays, which required venipuncture, were used to test for HIV infection. We extracted demographic, clinical, and visit characteristics from medical records and examined associations between these characteristics and accepting HIV testing using logistic regression. Of 300 patients, 35% agreed to HIV testing, with no new HIV infections detected. Common reasons for declining testing were perceived low risk (54.4%) and self-reported HIV testing previously (45.1%). Younger age (adjusted odds ratio [AOR] = 0.97, 95% confidence interval [CI] = 0.96-0.99), Hispanic ethnicity (AOR = 1.78, 95% CI = 1.01-3.14), and having another blood test during the visit (AOR = 6.36, 95% CI = 3.58-11.28) were independently associated with accepting HIV testing. This study questions whether expanding HIV testing by conducting routine opt-out HIV testing in primary care settings is an acceptable strategy. It is important to understand how various testing strategies may affect HIV testing rates. In addition, further exploration of patients' reasons for declining HIV testing in these settings is warranted.

Conspiracy beliefs regarding the origins of HIV are common among African Americans, and have been associated with engaging in HIV risk behaviors but also with earlier diagnosis among HIV patients. The objective of the present study was to test the association of HIV serostatus testing with conspiracy beliefs. A total of 1430 African Americans from low-income neighborhoods with high rates of drug use were surveyed in 1997-1999 in face-to-face interviews. Two 4-point items assessed if participants agreed that "AIDS was started by an experiment that went wrong" and "AIDS was created to kill blacks and poor folks." A binary variable indicated if the respondent agreed with the statements, on average. 22.5% of the sample endorsed conspiracy beliefs, 4.0% of whom reported not having had an HIV test, compared to 7.7% of those who did not endorse conspiracy beliefs. In multivariable logistic regression modeling, never having had an HIV test was significantly associated with conspiracy beliefs (adjusted odds ratio [AOR] = 0.43, 95% confidence interval [CI] = 1.3-4.3), having a high school education (AOR = 0.55, CI = 0.35-0.84), having depression (AOR = 1.61, CI = 1.02-2.52), female gender (AOR = 0.54, CI = 0.34-0.86), younger age, and a history of injection drug use (AOR = 0.36, CI = 0.23-0.56), but not sex risk behaviors (multiple partners, irregular condom use). The finding that individuals who have conspiracy beliefs are more likely to have been tested for HIV may partially explain why HIV-positive individuals who endorse conspiracy beliefs are more likely to obtain an earlier diagnosis.

In India men who have sex with men (MSM) are stigmatized, understudied, and at high risk for HIV. Understanding the impact of psychosocial issues on HIV risk behavior and HIV infection can help shape culturally relevant HIV prevention interventions. Peer outreach workers recruited 210 MSM in Chennai who completed an interviewer-administered psychosocial assessment battery and underwent HIV testing and counseling. More than one fifth (46/210) reported unprotected anal intercourse in the past 3 months, 8% tested positive for HIV, and 26% had previously participated in an HIV prevention intervention. In a multivariable logistic-regression model controlling for age, MSM subpopulation (kothi, panthi, or double-decker), marital status, and religion, significant predictors of any unprotected anal intercourse were being less educated (adjusted odds ratio [AOR] = .54; p = .009), not having previously participated in an HIV prevention program (AOR = 3.75; p = .05), having clinically significant depression symptoms (AOR = 2.8; p = .02), and lower self-efficacy (AOR = .40; p < .0001). Significant predictors of testing positive for HIV infection were: being less educated (AOR = .53; .05) and not currently living with parent(s) (AOR = 3.71; p = .05). Given the prevalence of HIV among MSM, efforts to reach hidden subpopulations of MSM in India are still needed. Such programs for MSM in India may need to address culturally-relevant commonly cooccurring psychosocial problems to maximize chances of reducing risk for infection.

Telephone surveys with national probability samples of English-speaking adults have suggested that popular support for punitive policies toward people living with HIV/AIDS (PLWHA) declined in the 1990s, but AIDS-related stigma persists in the United States. Our aim was to assess the prevalence and impact of AIDS-related stigma in non-Hispanic Black and Hispanic communities. A cross-sectional computer-assisted telephone-interview survey was conducted in summer 2003 with African-American, Afro-Caribbean, Haitian, and Hispanic 18-39 year-old residents of 12 high AIDS-incidence areas in Broward County, Florida. Stigma items were adopted from national surveys, but interviews were conducted in Spanish and Haitian Creole as well as in English. Stigma scores were higher than those reported for national samples, especially among Haitians interviewed in Creole. AIDS-related stigma was associated with never receiving an HIV-antibody test (adjusted odds ratio [AOR] = 0.78, 95% confidence interval [CI]: 0.62-0.99, P = .046), an elevated perception of HIV risk (AOR = 1.32, 95% CI: 1.01-1.73, P = .045) and a failure to participate in HIV-prevention efforts (AOR = 0.53, 95% CI: 0.34-0.85, P = .008). Interventions are needed to mitigate the pernicious effects of AIDS-related stigma.
