The continuing HIV epidemic among men who have sex with men

The Miami, Florida, Young Men's Survey: HIV prevalence and risk behaviors among urban young men who have sex with men who have ever runaway

Youth in urban areas with a history of running away from home often have special needs. Importantly, risk factors for HIV/AIDS might be associated with such a history. We assessed the association between having a history of running away from home and the occurrence of HIV infection and risk behavior among young men who have sex with men (YMSM), aged 15-22 years. A cross-sectional epidemiologic and behavioral survey was conducted between 1995 and 1996 in Miami, Florida, as part of a national Young Men's Survey. Of 488 YMSM, the prevalence of HIV infection among those with a history of running away from home was 10.5% (adjusted odds ratio=3.4; 95% CI 1.5-7.8). YMSM who had ever run away were more likely to be HIV infected, be out of school, and have ever had vaginal or anal sex with females, been forced to have sex, injected drugs, and used needles for self-tattooing or body piercing. The prevalence of HIV infection and associated risk behaviors among runaways was high, highlighting the ongoing need for prevention and social support services for youth with a history of running away from home.

Community planning, HIV prevention, and a needs assessment for men who have sex with men: the South Beach Health Survey

OBJECTIVE

The objective of this study was to plan for a series of culturally competent and sexually appropriate public health interventions for a highly mobile population of men who have sex with men (MSM).

GOAL

The goal of this study was to conduct a comprehensive needs assessment.

STUDY

A cross-sectional survey with a multistage probability sample of unmarried adult MSM living in households was conducted.

RESULTS

A total of 918 residential units were screened, 154 eligible men were identified, and 140 mostly white (56%) and Hispanic (34%) MSM (median=33.5 years old) were enrolled (90.9% response rate). Almost half (47%) reported engaging in unprotected anal intercourse in the previous 12 months. Drug use was common. Almost one third (31.0%) tested positive for the HIV antibody. Estimated annual incidence of HIV infection was 10.0%.

CONCLUSIONS

Population-based HIV antibody testing revealed a remarkably high annual incidence of HIV infection. A community-based organization was transformed to implement a social marketing campaign and provide other disease prevention services for MSM.

Unrecognized HIV infection, risk behaviors, and perceptions of risk among young men who have sex with men: opportunities for advancing HIV prevention in the third decade of HIV/AIDS

This study evaluated the magnitude and distribution of unrecognized HIV infection among young men who have sex with men (MSM) and of those with unrecognized infection, the prevalence and correlates of unprotected anal intercourse (UAI), perceived low risk for infection, and delayed HIV testing. MSM aged 15-29 years were approached, interviewed, counseled, and tested for HIV at 263 randomly sampled venues in 6 US cities from 1994-2000. Of 5649 MSM participants, 573 (10%) tested positive for HIV. Of these, 91% of black, 69% of Hispanic, and 60% of white MSM (77% overall) were unaware of their infection. The 439 MSM with unrecognized infection reported a total of 2253 male sex partners in the previous 6 months; 51% had UAI; 59% perceived that they were at low risk for being infected; and 55% had not tested in the previous year. The HIV epidemic among MSM in the United States continues unabated, in part, because many young HIV-infected MSM are unaware of their infection and unknowingly expose their partners to HIV. To advance HIV prevention in the third decade of HIV/AIDS, prevention programs must reduce unrecognized infection among young MSM by increasing the demand for and availability of HIV testing services.

Changes in HIV and AIDS in the United States: Entering the third decade

The epidemiology of the HIV transmission in the United States has changed considerably since the epidemic began. Our increased understanding of the virus has fostered development of new treatments to prolong life, and vaccine research has increased hope for those at risk in both developed and less developed countries. In this review, we provide information about current trends in HIV and AIDS among those in the United States most affected by the epidemic.

Moving for care: findings from the US HIV Cost and Services Utilization Study

This paper examines sociodemographic and HIV-related factors associated with moving post-HIV diagnosis for non-care- and care-related reasons (versus never moving post-HIV diagnosis). Distinctions are made between those who move for informal care only, formal care only, or informal and formal care. Data come from the nationally representative US HIV Cost and Services Utilization Study (N=2,864). Overall, 31.8% moved at least once post-HIV diagnosis and 16.3% moved most recently for care. Among those who moved for care, 32.6% moved for informal care only, 26.8% for formal care only, and 40.6% moved for both. Post-HIV diagnosis moves for reasons unrelated to care were less likely among African Americans and older persons, and more likely among those with longer durations positive. Moves for care were less likely among African Americans, older persons, and persons with higher educational attainments, while they were more likely among those with an AIDS diagnosis and longer durations HIV-positive. Among those who moved for care, women and persons with higher incomes were less likely to move for formal or mixed care than informal care only. Given that moving for care may reflect disparities in access to care and unmet needs, additional analyses with more detailed data are warranted.

Drug and sexual risk in four men who have sex with men populations: evidence for a sustained HIV epidemic in New York City

The objective of this article was to examine drug and sexual risk in four salient groups of men who have sex with men (MSM) in New York City (NYC): (1) nonhomeless young MSM (YMSM), (2) homeless YMSM, (3) adult MSM Speed users, and (4) HIV-positive "POZ Party" MSM. Lifetime and current exposure to drugs, drug injection, and selected drug-sex interactions are highlighted in each group. Data derive from recently completed field-based, ethnoepidemiological studies that used venue-oriented/targeted sampling and semistructured interviews. Across all four groups, findings show that both drug and sexual risk remain prevalent in the MSM population in NYC. This is especially troubling given the already high background prevalence of HIV and other sexually transmitted diseases in NYC and the widespread suffering and death already wrought by HIV/AIDS among MSM. These findings suggest that available public health interventions today are, in many respects, failing to reach, engage, and affect critical risk groups within the NYC MSM population.

HIV prevalence and risk behaviors among men who have sex with men and inject drugs in San Francisco

The dual risks of male-to-male sex and drug injection have put men who have sex with men and inject drugs (MSM-IDU) at the forefront of the HIV epidemic, with the highest rates of infection among any risk group in the United.States. This study analyzes data collected from 357 MSM-IDU in San Francisco between 1998 and 2002 to examine how risk behaviors differ by HIV serostatus and self-identified sexual orientation and to assess medical and social service utilization among HIV-positive MSM-IDU. Twenty-eight percent of the sample tested HIV antibody positive. There was little difference in risk behaviors between HIV-negative and HIV-positive MSM-IDU. Thirty percent of HIV-positive MSM-IDU reported distributive syringe sharing, compared to 40% of HIV negatives. Among MSM-IDU who reported anal intercourse in past 6 months, 70% of positives and 66% of HIV negatives reported unprotected anal intercourse. HIV status varied greatly by self-identified sexual orientation: 46% among gay, 24% among bisexual, and 14% among heterosexual MSM-IDU. Heterosexual MSM-IDU were more likely than other MSM-IDU to be homeless and to trade sex for money or drugs. Gay MSM-IDU were more likely to have anal intercourse. Bisexual MSM-IDU were as likely as heterosexual MSM-IDU to have sex with women and as likely as gay-identified MSM-IDU to have anal intercourse. Among MSM-IDU who were HIV positive, 15% were currently on antiretroviral therapy and 18% were currently in drug treatment, and 87% reported using a syringe exchange program in the past 6 months. These findings have implications for the development of HIV interventions that target the diverse MSM-IDU population.

Recruiting drug-using men who have sex with men into behavioral interventions: a two-stage approach

Drug-using men who have sex with men (MSM) are at high risk of acquiring or transmitting HIV infection. Efforts to change behaviors in this population have been hampered by difficulties in recruiting drug-using MSM into behavioral interventions. This study sought to develop an effective strategy for recruiting drug-using MSM into behavioral interventions that consist of motivational interviewing alone or motivational interviewing plus contingency management. MSM were recruited through advertising and community outreach into groups to discuss party drugs, party burnout, and sexual behavior, with the intervention subsequently described and enrollment offered in the group setting. Many more eligible MSM responded to advertisements for the discussion groups than advertisements for the interventions, and 58% of those who participated in the discussion groups volunteered for counseling. Men who entered counseling reported high levels of drug use and sexual activity and were racially and ethnically diverse; only 35% were willing to accept drug treatment. Results demonstrate that a two-stage strategy in which drug-using MSM are first recruited into discussion groups before they are offered a behavioral intervention can be an effective way to induce voluntary acceptance of an intervention employing a behavioral risk-reduction approach.

Longitudinal patterns of methamphetamine, popper (amyl nitrite), and cocaine use and high-risk sexual behavior among a cohort of san francisco men who have sex with men

Most prior studies examining drug use among men who have sex with men (MSM) have been cross-sectional or retrospective and have not determined whether periods of increased drug use are associated with high-risk sexual behavior at the individual level. In this article, we describe patterns of use of methamphetamines, poppers, and sniffed cocaine and sexual risk behavior among 736 San Francisco MSM enrolled in the EXPLORE study and followed for up to 48 months. In longitudinal analysis, use of methamphetamines, poppers, and sniffed cocaine declined during follow-up. However, compared with older participants, younger participants were more likely to increase their drug use over time. Results of conditional logistic regression demonstrated that high-risk sexual behavior was more common during reporting periods characterized by increased methamphetamine, poppers, or sniffed cocaine use. This within-person analysis found that compared with periods of no drug use, periods of both light drug use (less than weekly use of drugs) and heavier drug use (at least weekly use of at least one drug) were significantly associated with increased risk of engaging in unprotected anal sex with an HIV-positive or unknown-status partner. These results suggest that even intermittent, recreational use of these drugs may lead to high-risk sexual behavior, and that, to reduce and prevent risks of HIV, no level of use of these drugs should be considered "safe." HIV prevention interventions should target MSM who report either light or heavy use of methamphetamines, poppers, and sniffed cocaine.

Higher prevalence of childhood sexual abuse among Latino men who have sex with men than non-Latino men who have sex with men: data from the Urban Men's Health Study

OBJECTIVE

The prevalence of childhood sexual abuse among Latino adult men who have sex with men who live in the US was estimated because a history of childhood sexual abuse increases HIV sexual risk behaviors and other negative health outcomes in adulthood.

METHOD

The Urban Men's Health Study is a random-digit telephone probability survey of 2881 adult men who have sex with men (MSM) aged 18 years or older residing in San Francisco, New York, Los Angeles, and Chicago. Self-reported history of childhood sexual abuse was the main outcome measure gathered from 2692 MSM.

RESULTS

A significantly higher proportion of Latino MSM reported sexual abuse before age 13 (22%) than did non-Latino MSM (11%).

CONCLUSIONS

Latino MSM are twice as likely to report a history of childhood sexual abuse than are non-Latino MSM. Given the association between childhood sexual abuse and increased risk for HIV and other negative health outcomes, health providers must remain vigilant to the possibility of childhood sexual abuse histories among their Latino patients.

A comparison of HIV seropositive and seronegative young adult heroin- and cocaine-using men who have sex with men in New York City, 2000-2003

The purpose of this analysis was to determine the prevalence and correlates of HIV infection among a street-recruited sample of heroin- and cocaine-using men who have sex with men (MSM). Injection (injecting <or=3 years) and non-injection drug users (heroin, crack, and/or cocaine use <10 years) between 18 and 40 years of age were simultaneously street-recruited into two cohort studies in New York City, 2000-2003, by using identical recruitment techniques. Baseline data collected among young adult men who either identified as gay/bisexual or reported ever having sex with a man were used for this analysis. Nonparametric statistics guided interpretation. Of 95 heroin/ cocaine-using MSM, 25.3% tested HIV seropositive with 75% reporting a previous HIV diagnosis. The majority was black (46%) or Hispanic (44%), and the median age was 28 years (range 18-40). HIV-seropositive MSM were more likely than seronegatives to be older and to have an HIV-seropositive partner but less likely to report current homelessness, illegal income, heterosexual identity, multiple sex partners, female partners, and sex for money/drug partners than seronegatives. These data indicate high HIV prevalence among street-recruited, drug-using MSM compared with other injection drug use (IDU) subgroups and drug-using MSM; however, lower risk behaviors were found among HIV seropositives compared with seronegatives. Large-scale studies among illicit drug-using MSM from more marginalized neighborhoods are warranted.

Tobacco use and cessation among a household-based sample of US urban men who have sex with men

OBJECTIVES

We examined tobacco use and cessation among a probability sample of urban men who have sex with men (MSM) living in 4 large US cities.

METHODS

Of the 2402 men who were eligible for follow-up from a previously recruited probability sample, 1780 (74%) completed tobacco surveys between January and December 1999.

RESULTS

Current smoking rates were higher for urban MSM (31.4%; 95% confidence interval [CI]=28.6%, 34.3%) than for men in the general population (24.7%; 95% CI=21.2%, 28.2%). Among MSM, 27% were former smokers. A complex set of sociodemographic, tobacco-related, and other factors were associated with cessation.

CONCLUSIONS

Results support earlier reports that smoking rates are higher for MSM compared with men in the general population. Findings related to cessation underscore the need to target tobacco control efforts for MSM.

Seroprevalence of and risk factors for HIV-1 infection among South American men who have sex with men

OBJECTIVES

Sex among men constitutes an important route of transmission for HIV type 1 (HIV-1) in Latin America. Seeking better understanding of risk behaviours in this region, we determined the seroprevalence, potential risk factors, and geographic distribution of HIV-1 among groups of men who have sex with men (MSM).

METHODS

Seroepidemiological, cross sectional studies of 13,847 MSM were conducted in seven countries of South America during the years 1999-2002. Volunteers were recruited in city venues and streets where anonymous questionnaires and blood samples were obtained. HIV-1 infection was determined by enzyme linked immunosorbent assay (ELISA) screening and western blot (WB) confirmatory tests.

RESULTS

HIV-1 seroprevalence varied widely (overall 12.3%, range 11.0%-20.6%). The highest HIV-1 seroprevalence was noted in Bolivia (20.6%) and the lowest in Peru (11.0%). Predictors of HIV-1 infection varied among countries; however, a history of previous sexually transmitted disease (STD) was associated with a consistent increased risk (ORs=1.9-2.9, AORs=1.8-2.7). Multiple weekly sexual contacts was found to represent a secondary risk factor in Ecuador, Peru, and Argentina (ORs=1.6-2.9, AORs=1.6-3.1), whereas use of drugs such as cocaine was found to increase risk in Bolivia, Uruguay, and Paraguay (ORs=2.5-6.5, AORs=2.6-6.1).

CONCLUSION

The results of this study illustrate an elevated HIV-1 seroprevalence among MSM participants from Andean countries. A previous STD history and multiple partners predicted HIV-1 infection in the seven countries of South America. In Southern Cone countries, HIV-1 infection was also associated with use of illegal drugs such as cocaine.

HIV related behaviours and attitudes among Chinese men who have sex with men in Hong Kong: a population based study

OBJECTIVE

This study was conducted in order to determine the prevalence of men having sex with men (MSM) and their HIV related behaviours and attitudes among Chinese men in Hong Kong.

METHODS

A large scale, random, population based, anonymous telephone survey of 14 963 men between the ages of 18-60 was conducted. The overall response rate was approximately 57%.

RESULTS

Of the respondents, 4.6% had ever engaged in MSM activity. In the 6 months preceding the survey, 2.0% had engaged in MSM behaviours (active MSM) and 0.5% reported having engaged in anal sex MSM behaviours. Among anal sex MSM, consistent condom use was 42.9% with male non-commercial sex partners and even lower with male commercial sex partners (35.7%). Approximately 11% of anal sex MSM and 4.1% of the non-anal sex MSM had contracted an STD in the last 6 months. The prevalence of HIV testing was only 20.6% among anal sex MSM and 11.9% among non-anal sex MSM.

CONCLUSIONS

Active MSM in Hong Kong are at high risk of HIV infection. The belief of low vulnerability to HIV is prevalent among active MSM in Hong Kong with only 2.0% believing that their chances of HIV infection as being "very likely."

Changes in HIV and AID in the United States: Entering the third decade

The epidemiology of the HIV transmission in the United States has changed considerably since the epidemic began. Our increased understanding of the virus has fostered development of new treatments to prolong life, and vaccine research has increased hope for those at risk in both developed and less developed countries. In this review, we provide information about current trends in HIV and AIDS among those in the United States most affected by the epidemic.

A Case–Control Study of Syphilis Among Men Who Have Sex With Men in New York City

OBJECTIVE

The objective of this study was to determine factors associated with syphilis among men who report sex with other men in New York City. DESIGN, SETTING AND STUDY SUBJECTS: We conducted a case-control study among 88 men who reported sex with men in the previous year, 18 to 55 years old and diagnosed with primary or secondary syphilis during 2001; and 176 control subjects frequently matched by age and type of health provider.

RESULTS

HIV prevalence among syphilis cases was 48% compared with 15% among control subjects (P <0.001). Variables associated with syphilis in a multivariate model were HIV infection (odds ratio [OR], 7.3; 95% confidence interval [CI], 3.5-15.4), income >$30,000 per year (OR, 2.7; CI, 1.4-5.2), and barebacking (OR, 2.6; CI, 1.4-4.8). The median time since HIV diagnosis for HIV-positive was 6 years for cases and 7 years for control subjects (P = 0.70). Among HIV-infected participants, syphilis cases were more likely than control subjects to report being on antiretroviral therapy (69% vs. 44%, P = 0.05) and to report having undetectable viral load (58% vs. 24%, P = 0.02).

CONCLUSION

HIV infection was strongly associated with syphilis in this study. High-risk behavior reported by both cases and control subjects indicates the potential for increased HIV transmission.

Trends in HIV Prevalence Among Public Sexually Transmitted Disease Clinic Attendees in the Western Region of the United States (1989???1999)

OBJECTIVES

Using data from anonymous unlinked testing of routinely collected sera, trends in HIV are compared among sexually transmitted disease patients in 4 Western urban centers.

METHODS

Between 1989 and 1999, remnant sera obtained for routine syphilis testing from 256,819 patient visits to Denver, Los Angeles, San Francisco, and Seattle clinics were tested for HIV antibodies in an unlinked survey. HIV antibody test results were linked to anonymous demographic and risk information abstracted from the medical record.

RESULTS

Overall cumulative HIV seroprevalences among women and among men who had sex exclusively with women were < or = 2%, declined over time, and did not exceed 8% among those who injected drugs. In contrast, cumulative HIV seroprevalences among men who have sex with men ranged from 13% in Seattle to 30% in San Francisco and declined a mean of 2.1% (95% CI, 1.6, 2.6) to 2.8% (CI 2.6, 3.1) per year, after adjustment.

CONCLUSIONS

HIV infection declined over time across counties. Relative levels of HIV differed little by demographic and behavioral risk group despite differences in the severity of each county's epidemic. Because of the unique contribution of unlinked serosurveillance studies in monitoring these trends, their reinstitution in high-risk settings should be considered.

An HIV prevalence-based model for estimating urban risk populations of injection drug users and men who have sex with men

Issues of cost and complexity have limited the study of the population sizes of men who have sex with men (MSM) and injection drug users (IDUs), two groups at clearly increased risk for human immunodeficiency virus (HIV) and other acute and chronic diseases. We developed a prototypical, easily applied estimation model for these populations and applied it to Miami, Florida. This model combined HIV prevalence estimates, HIV seroprevalence rates, and census data to make plausible estimates of the number and proportion of MSM and IDUs under a number of assumptions. Sensitivity analyses were conducted to test the robustness of the model. The model suggests that approximately 9.5% (plausible range 7.7%-11.3%) of Miami males aged 18 years or older are MSM (point estimate, N = 76,500), and 1.4% (plausible range 0.9%-1.9%) of the total population aged 18 years or older are IDUs (point estimate, N = 23,700). Males may be about 2.5 times more likely than females to be IDUs. The estimates were reasonably robust to biases. The model was used to develop MSM and IDU population estimates in selected urban areas across Florida and should be replicable in other medium-to-large urban areas. Such estimates could be useful for behavioral surveillance and resource allocation, including enhanced targeting of community-based interventions for primary and secondary HIV prevention.

Predictors of risky sexual behavior among young African American men who have sex with men

This study examined the prevalence and correlates of unprotected anal intercourse among 758 young African American men who have sex with men. A quarter of the sample reported unprotected anal intercourse in the past 3 months; nonsupportive peer norms and not carrying condoms predicted risky sexual behavior. Effective interventions are needed that promote the use of condoms by changing peer norms and encouraging carrying condoms.

HIV seroprevalence among homeless and marginally housed adults in San Francisco

OBJECTIVES

We report HIV seroprevalence and risk factors for urban indigent adults.

METHODS

A total of 2508 adults from shelters, meal programs, and low-cost hotels received interviews, blood tests, and tuberculosis screening.

RESULTS

Seroprevalence was 10.5% overall, 29.6% for men reporting sex with men (MSM), 7.7% for non-MSM injection drug users (IDUs), and 5.0% for residual non-MSM/non-IDUs. Risk factors were identified for MSM (sex trade among Whites, non-White race, recent receptive anal sex, syphilis), non-MSM IDUs (syphilis, lower education, prison, syringe sharing, transfusion), and residual subjects (> or = 5 recent sexual partners, female crack users who gave sex for drugs).

CONCLUSIONS

HIV seroprevalence was 5 times greater for indigent adults than in San Francisco generally. Sexual behavior predicted HIV infection better than drug use, even among IDUs.

Prevalence of non-medical drug use and dependence among homosexually active men and women in the US population

AIMS

The aim of this study was to compare patterns of drug use and dependence between homosexually experienced and exclusively heterosexually experienced individuals.

DESIGN

We used a cross-sectional national household interview survey conducted in the United States.

SETTING

Secondary data analysis of the 1996 National Household Survey on Drug Abuse was employed.

PARTICIPANTS

Participants were sexually active individuals, aged 18 years and older, who reported the genders of their sexual partners in the past 12 months; included 174 homosexually experienced (98 men, 96 women) and 9714 exclusively heterosexually experienced (3922 men, 5792 women) respondents.

MEASUREMENTS

Life-time, past 30 days and daily use of nine classes of drugs. Symptoms of dysfunctional use and dependence.

FINDINGS

There were consistent patterns of elevated drug use in homosexually experienced individuals for life-time drug use, but these were greatly attenuated for recent use. Homosexually experienced men were more likely to report use of marijuana, cocaine and heroin, and homosexually experienced women more likely to report use of marijuana and analgesics than individuals reporting only opposite-sex partners. Both homosexually active men and women were more likely than exclusively heterosexually active respondents to report at least one symptom indicating dysfunctional drug use across all drug classes, and to meet criteria for marijuana dependence syndrome. The only difference between homosexually experienced men and women was that men were more likely to report any daily drug use.

CONCLUSIONS

These data are consistent with surveys suggesting that there is a moderate elevation of drug, particularly marijuana, use and dependence in gay and bisexual men and women when compared to heterosexual men and women.

Effects of a behavioural intervention to reduce acquisition of HIV infection among men who have sex with men: the EXPLORE randomised controlled study

BACKGROUND

Effective interventions are needed to prevent acquisition of HIV infection in men who have sex with men. To date, no behavioural interventions specifically for this risk group have been tested with HIV infection as the primary outcome.

METHODS

This multisite two-group randomised controlled phase IIb trial tested the efficacy of a behavioural intervention in preventing HIV infection among 4295 men who have sex with men. The experimental intervention consisted of ten one-on-one counselling sessions followed by maintenance sessions every 3 months. The standard condition was twice-yearly Project RESPECT individual counselling. Twice-yearly follow-up visits included testing for HIV antibody and assessment of behavioural outcomes.

FINDINGS

The rate of acquisition of HIV infection was 18.2% (95% CI -4.7 to 36.0) lower in the intervention group than the standard group. Adjustment for baseline covariates attenuated the intervention effect to 15.7% (-8.4 to 34.4). The effect was more favourable in the first 12-18 months of follow-up. The occurrence of unprotected receptive anal intercourse with HIV-positive and unknown-status partners was 20.5% (10.9 to 29.0) lower in the intervention than in the standard group.

INTERPRETATION

The results from the primary analyses allow us to rule out that the experimental intervention is associated with a 35% lower rate of HIV acquisition than in the standard group. The overall estimate of a difference of 18.2%, more favourable estimates of effect in the first 12-18 months, and similar effects on risk behaviours suggest that prevention of HIV infection among men who have sex with men by a behavioural intervention is feasible. Further work should be done to develop more effective interventions.

Decline in HIV infectivity following the introduction of highly active antiretroviral therapy

OBJECTIVE

Little is known about the degree to which widespread use of antiretroviral therapy in a community reduces uninfected individuals' risk of acquiring HIV. We estimated the degree to which the probability of HIV infection from an infected partner (the infectivity) declined following the introduction of highly active antiretroviral therapy (HAART) in San Francisco.

DESIGN

Homosexual men from the San Francisco Young Men's Health Study, who were initially uninfected with HIV, were asked about sexual practices, and tested for HIV antibodies at each of four follow-up visits during a 6-year period spanning the advent of widespread use of HAART (1994-1999).

METHODS

We estimated the infectivity of HIV (per-partnership probability of transmission from an infected partner) using a probabilistic risk model based on observed incident infections and self-reported sexual risk behavior, and tested the hypothesis that infectivity was the same before and after HAART was introduced.

RESULTS

A total of 534 homosexual men were evaluated. Decreasing trends in HIV seroincidence were observed despite increases in reported number of unprotected receptive anal intercourse partners. Conservatively assuming a constant prevalence of HIV infection between 1994 and 1999, HIV infectivity decreased from 0.120 prior to widespread use of HAART, to 0.048 after the widespread use of HAART- a decline of 60% (P=0.028).

CONCLUSIONS

Use of HAART by infected persons in a community appears to reduce their infectiousness and therefore may provide an important HIV prevention tool.

Ambivalent tales of HIV disclosure in San Francisco

In light of rising levels of unprotected anal intercourse (UAI) among men who have sex with men (MSM) in San Francisco, we sought to understand disclosure practices, the calculus of risk and attitudes about HIV seroconversion. In 2000, 150 MSM participated in interviews pivoting around a detailed narrative of a recent incident of UAI. In order to understand the relationship between individual and community norms, we analyzed the narratives as accounts situated within the respondents' experience of the HIV epidemic and the gay community in San Francisco. In justifying their risky sexual practices, MSM cited a community-wide shift toward non-disclosure and barebacking since the advent of highly active anti-retroviral therapy (HAART). Fearing rejection by HIV-positive partners who refuse to use condoms, HIV-negative men saw little advantage in disclosing to casual partners whom they perceived as overwhelmingly HIV-positive. By contrast, HIV-positive men appeared eager to disclose their positive status to release themselves from responsibility for transmission and facilitate "bareback" or unprotected sex. Disavowal of individual responsibility for safer sex in deference to community norms may contribute to the recent spiraling of risk behavior and HIV incidence. Implications for prevention policy are discussed.

Changes in the transmission dynamics of the HIV epidemic after the wide-scale use of antiretroviral therapy could explain increases in sexually transmitted infections: results from mathematical models

BACKGROUND

Recent increases in bacterial sexually transmitted infections (STI) and risk behavior have coincided with the introduction of antiretroviral therapy (ART) in homosexual communities of industrialized countries. The reasons for these increases are not fully understood.

GOAL

The goal of this study was to understand the various effects of ART on risk behaviors and STI.

OBJECTIVE

The objective of this study was to assess the independent impact of the change in the transmission dynamics of HIV/AIDS as a result of the wide-scale use of ART on a bacterial STI.

STUDY DESIGN

We developed a mathematical model of bacterial STI and treated/untreated HIV/AIDS infection for an open homosexual population. At the individual level, we assume that susceptible and healthy HIV-positive individuals do not increase their risk behavior as a result of ART over time. However, individuals with AIDS, who are successfully treated with ART, can resume sexual activity. The impact of the wide-scale use of ART on risky behavior, STI, and HIV/AIDS was evaluated over a wide range of assumptions on treatment use, ART efficacy, and population characteristics.

RESULTS

Over 10 years, 0% to 55% new bacterial STI could be attributed to the wide-scale use of ART as a result of more modest increases (0-25%) in risky sex occurring at the population level rather than at the individual level. These increases have a negative impact on HIV if coverage is too low. Increasing treatment coverage helps to prevent more HIV infections despite larger increases in risky sex and STI that is predicted to ensue.

CONCLUSION

Taking the differential impact of wide-scale use of ART into account helps to interpret recent behavioral and STI trends. Our results have implications for prevention strategies and for the formulation of public health policies. A better understanding of the differential impact of ART on sexual network over time is required.

Racial disparities in sexual risk behaviors and drug use among older gay/bisexual and heterosexual men living with HIV/AIDS

Adults over age 50 comprise 11% of yearly AIDS cases, yet little is known about their sexual risk behaviors and drug use following diagnosis with HIV/AIDS. The present questionnaire study examines potential racial differences in sexual risk and drug use behaviors among 59 HIV-infected gay/bisexual and heterosexual men over age 50 who were recruited from HIV-related organizations in New York City between 1996-1998. The majority (59%) of older men reported unprotected sex since diagnosis, and 36% had done so in the past six months. African-American gay/bisexual men (n=12) were significantly more likely than white gay/bisexual men (n=32) to report unprotected vaginal/anal sex in the past six months (67% versus 22%, p<0.01), since diagnosis (42% versus 9%, p<0.05), and to report a history of intravenous drug use (50% versus 3%, p<0.01), but did not differ from heterosexual African-American men (n=15). No differences were found in reports of unprotected oral sex or recent use of hard drugs (i.e., crack, cocaine, heroin). These findings suggest that interventions targeting older African-American men (both gay/bisexual and heterosexual) with HIV/AIDS are needed to reduce risk behaviors and prevent HIV transmission in this population.

Decline in HIV infectivity following the introduction of highly active antiretroviral therapy

OBJECTIVE

Little is known about the degree to which widespread use of antiretroviral therapy in a community reduces uninfected individuals' risk of acquiring HIV. We estimated the degree to which the probability of HIV infection from an infected partner (the infectivity) declined following the introduction of highly active antiretroviral therapy (HAART) in San Francisco.

DESIGN

Homosexual men from the San Francisco Young Men's Health Study, who were initially uninfected with HIV, were asked about sexual practices, and tested for HIV antibodies at each of four follow-up visits during a 6-year period spanning the advent of widespread use of HAART (1994-1999).

METHODS

We estimated the infectivity of HIV (per-partnership probability of transmission from an infected partner) using a probabilistic risk model based on observed incident infections and self-reported sexual risk behavior, and tested the hypothesis that infectivity was the same before and after HAART was introduced.

RESULTS

A total of 534 homosexual men were evaluated. Decreasing trends in HIV seroincidence were observed despite increases in reported number of unprotected receptive anal intercourse partners. Conservatively assuming a constant prevalence of HIV infection between 1994 and 1999, HIV infectivity decreased from 0.120 prior to widespread use of HAART, to 0.048 after the widespread use of HAART- a decline of 60% (P=0.028).

CONCLUSIONS

Use of HAART by infected persons in a community appears to reduce their infectiousness and therefore may provide an important HIV prevention tool.

Alcohol Use and High-Risk Sexual Behavior Among Men Who Have Sex With Men: The Effects of Consumption Level and Partner Type

Alcohol use may increase HIV sexual risk behavior, although findings have varied across study populations and methods. Using event-level data from 1,712 seronegative men who have sex with men, the authors tested the hypothesis that social context would moderate the effect of alcohol consumption on unprotected anal sex (UAS). For encounters involving a primary partner, rates of UAS did not vary as a function of alcohol use. However, consumption of 4 or more drinks tripled the likelihood of UAS for episodes involving a nonprimary partner. Thus, the effects of alcohol vary according to the context in which it is used. Interventions to reduce substance-related risk should be tailored to the demands of maintaining sexual safety with nonprimary partners.

HIV Prevention Research: Are We Meeting the Needs of African American Men Who Have Sex With Men?

Two decades of HIV prevention efforts with men who have sex with men (MSM) have not eliminated the risk of new HIV infections in this vulnerable population. Indeed, current incidence rates in African American MSM are similar to those usually only seen in developing countries. A review of the existing literature suggests that the prevention research agenda for Black MSM could benefit from reframing conceptualization of risk as a function of individual properties to a broad consideration of social and interpersonal determinants. Studies that investigate dyadic and social-level influences on African American MSM's relationships are needed. This includes research explicating the diversity existing within the categorizations of Black MSM with respect to perceived identity (gay, bisexual, "men on the down low," "homo thugz"), constructions of masculinity, sexual scripts, sources of social support, and perceived norms and expectations. Recommendations are proposed for a research agenda focusing on linkages between interpersonal and social-structural determinants of HIV risk.

The social course of drug injection and sexual activity among YMSM and other high-risk youth: an agenda for future research

The cumulative epidemiologic literature indicates that many injecting drug users (IDUs) initiate injection as a mode of drug administration during late adolescence or early adulthood. Recent studies have shown that IDUs are often exposed to viral infections relatively early in the course of injection, highlighting the importance of understanding this initiation process for both epidemiology and prevention. Epidemiologic evidence similarly suggests that at least some youth populations, most notably young men who have sex with men (YMSM), are at substantial risk for exposure to HIV and other sexually transmitted diseases (STDs) from early sexual activity. Despite the importance of this issue for both epidemiology and prevention, however, surprisingly little information is available on the social course of injection initiation, including the individual, social, or ecological factors that might mitigate or exacerbate transmission risks within the critical phase of early injection drug use. Similarly, we know little about the ways that YMSM and other high-risk youth understand risk, the kinds of exchanges and relationships in which they participate in the context of initiating sexual activity, or how drug use is operant in these exchanges and early sexual experiences. In this article, we explore key dimensions of the early initiation of injection and sexual risk, and discuss how a social network approach might be instrumental in understanding the social course of drug injection and sexual activities among youth and young adult populations.

Effects of immigration on selected health risk behaviors of Black college students

The authors administered the National College Health Risk Behavior Survey to 1,219 college students who were attending a historically Black college located in New York City. They assessed the US-born Black students and Black students who emigrated to the United States for differences in risky sexual behaviors, risky dietary behaviors, and physical inactivity. They used bivariate and multiple regression analyses to analyze the data and observed significant differences between the US-born and non-US-born students in the behavioral domains of risky sexual behaviors (p = .003), risky dietary behaviors (p = .001), and physical inactivity (p = .010). They conclude that immigration is associated with health protective behavior in the domains of sexual behavior and physical activity among the Black college students attending this particular institution. However, in the domain of dietary intake, immigration status was associated with increased risk in these Black college students.

Drug injection and sexual mixing patterns of drug-using male sex workers

BACKGROUND

Drug-using male sex workers (DUMSWs) are known to have large numbers of drug injection and sex partners.

GOALS

The purpose of this study was to describe the assortative and disassortative drug injection and sexual mixing patterns of DUMSWs. Implications of the high rates of disassortative mixing patterns of DUMSWs for HIV infection are discussed. Implications of disassortative mixing of DUMSWS with regard to DUMSWs bridging disparate HIV risk groups are evaluated.

STUDY DESIGN

Data were collected from 89 DUMSWS. Data on up to six drug injection and six sex partners were collected from respondents. One hundred drug injection and 169 sex respondent/partner pairs were analyzed for the proportions of pairs that were concordant (like) or discordant (unlike) in gender, trading sex for money, race/ethnicity, and age cohort. For race/ethnicity and age, within-group differences were assessed with chi-square statistics.

RESULTS

Data showed high proportions of discordant respondent/partner pairs for both drug injection and sex by gender, trading sex for money, race/ethnicity, and age. Significant within-group differences in rates of discordant pairs were found for both behaviors in relation to race/ethnicity and age. Minority persons and respondents 19 years of age or younger were more likely to be in discordant pairs.

CONCLUSIONS

Direct assessment of HIV risk posed by the mixing patterns was not possible. Elaborating the mechanisms by which DUMSWs might act as an epidemiologic bridge is complex and involves more variables than were explored in this study. Nevertheless, such a study would be worthwhile.

HIV infection and associated risks among young men who have sex with men in a Florida resort community

OBJECTIVE

Several recent studies have reported high rates of sexual risk-taking and HIV infection among young men who have sex with men (MSM). Most of these studies used samples of convenience. The authors obtained population-based data on young MSM living in South Beach (Miami Beach, Florida), a resort community where some of the highest AIDS rates in the United States have been reported.

METHODS

A household probability sample was drawn to survey unmarried 18- to 29-year-old MSM living in South Beach. Subjects were interviewed, completed self-administered questionnaires, and provided oral specimens for HIV antibody testing.

RESULTS

From the 2,622 screened residential units, 100 mostly white and Hispanic MSM (92.6% of eligible participants) were enrolled in the study. Fifteen percent of the sample tested positive for antibodies to HIV. White and Hispanic MSM had similar rates. Forty-five percent of the sample reported engaging in unprotected anal intercourse (UAI) in the prior 12 months, and 31% reported UAI with a nonprimary partner. The estimated annual incidence of HIV infection was 6.3%.

CONCLUSION

The high prevalences of UAI and HIV infection in South Beach attest to a previously undocumented public health concern. The extremely high estimated incidence for young MSM in South Beach highlights the urgent need for more effective risk-reduction interventions and further epidemiological research on resort areas.

The HIV epidemic among older men who have sex with men

The authors present HIV prevalence and risk behavior data for urban men who have sex with men (MSM) aged 50 years or older. Data are based on a probability sample of MSM conducted in 1997 (n = 2881 total; 507 older MSM) in New York, Los Angeles, Chicago, and San Francisco. The authors determined HIV status through self-report and biologic measures. Risk behavior was assessed through self-report. The authors found that HIV prevalence was 19% (95% CI: 14, 25) for men in their 50s and 3% (95% CI: 1, 10) for men in their 60s. No men in their 70s were HIV-positive. Prevalence was at high levels for older blacks (30%), MSM who are injection drug users (21%), moderately heavy drug users (35%), and less closeted men (21%). High-risk sex between serodiscordant partners was relatively constant (4%-5%) across age groups older than 30 years of age and decreased among MSM in their 70s. Current levels of HIV among older urban MSM in the United States are very high, particularly among those in their 50s. High mortality rates among MSM with AIDS up to 1996 (before highly active antiretroviral therapy [HAART]) would account for the lower levels among men in their 60s and 70s. Because of HAART, we would expect HIV levels to increase in these age groups. Given high levels of risk behavior among MSM through the sixth decade of life, the authors would expect an older MSM epidemic of substantially larger proportion than that observed in the 1980s and 1990s.

An individually tailored intervention for HIV prevention: baseline data from the EXPLORE Study

OBJECTIVES

We describe the intervention tested in EXPLORE, an HIV prevention trial aimed at men who have sex with men (MSM), and test the empirical basis of the individually tailored intervention.

METHODS

Data on participants' self-efficacy, communication skills, social norms, and enjoyment of unprotected anal intercourse were examined in relation to sexual risk. Combinations of these factors, together with alcohol use and noninjection drug use, were also examined.

RESULTS

The individual factors examined were associated with sexual risk behavior. The cohort was shown to be heterogeneous in regard to the presence of combinations of these risk-related factors.

CONCLUSIONS

Baseline data from the EXPLORE study support the efficacy of the individually tailored intervention used.

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.

Designing effective HIV/AIDS social and behavioral interventions for the population of those age 50 and older

Social and behavioral HIV/AIDS prevention interventions designed to test their effects on older cohorts are sorely lacking in the scientific literature even though middle-aged and older people represent a significant minority of both existing and new AIDS cases. This article raises key issues relevant in developing and evaluating HIV/AIDS social and behavioral interventions for older cohorts. These interventions must build on our current understanding of behavior change and HIV prevention successes with younger populations while considering important intervention principles gathered from work with older populations in other health arenas. In addition, the authors expand on recent national panels and published reviews relevant to the topic and provide a set of intervention recommendations for use in tandem with these intervention principles. The article also calls for additional research into the sociocultural contexts that influence risk-taking among older cohorts and for the development of interventions at multiple levels. Pragmatic considerations such as identifying and dismantling ageism in interventions, delineating intervention outcomes, and planning for intervention transferability, dissemination, and sustainability also are raised.

Association of co-occurring psychosocial health problems and increased vulnerability to HIV/AIDS among urban men who have sex with men

OBJECTIVES

We measured the extent to which a set of psychosocial health problems have an additive effect on increasing HIV risk among men who have sex with men (MSM).

METHODS

We conducted a cross-sectional household probability telephone sample of MSM in Chicago, Los Angeles, New York, and San Francisco.

RESULTS

Psychosocial health problems are highly intercorrelated among urban MSM. Greater numbers of health problems are significantly and positively associated with high-risk sexual behavior and HIV infection.

CONCLUSIONS

AIDS prevention among MSM has overwhelmingly focused on sexual risk alone. Other health problems among MSM not only are important in their own right, but also may interact to increase HIV risk. HIV prevention might become more effective by addressing the broader health concerns of MSM while also focusing on sexual risks.

Social support, distress, and well-being in older men living with HIV infection

Older men with HIV infection/AIDS, having often lived with the condition longer, are more likely to confront the stress of managing more advanced HIV disease than their younger counterparts. Meanwhile, they also are more likely to have less social support and experience more distress than younger persons with HIV infection. The moderating effect of social support on health functioning and distress is unknown for persons with HIV infection, particularly those who are older. Study objectives were to assess whether the association between perceived health functioning and psychological distress and well-being is moderated (or influenced) by social support and age and if the impact of social support on distress and well-being is more pronounced for older than for younger men living with HIV infection/AIDS. In this cross-sectional study of HIV-positive adult men (n = 199) who have sex with men, participants completed self-report assessments of perceived health functioning, social support, and psychological distress and well-being. Measures of health functioning and overall social support were significantly associated with outcome measures of distress and positive affect (all p < .05). However, the main effect for social support was qualified by a significant age-by-social support interaction for both outcomes (beta = -.190, p < .01 for distress; beta = .172, p < .05 for positive affect), indicating that the impact of social support on decreasing distress and increasing well-being was more pronounced in older men. The relationships between perceived health functioning and distress and well-being were not moderated by social support or age. The influence of social support on negative and positive moods in this population of HIV-infected men who have sex with men was significantly greater among older than among younger participants. With an increasing number of older people with HIV infection/AIDS, special efforts to create effective and sustainable social support interventions may be particularly beneficial to older persons living with HIV infection.

Rectal use of nonoxynol-9 among men who have sex with men

OBJECTIVES

To assess recent rectal use of nonoxynol-9 (N-9), intent to use the product, and factors associated with N-9 use among men who have sex with men (MSM).

DESIGN

Cross-sectional survey of a diverse sample of MSM in the San Francisco Bay Area.

METHODS

Recruitment conducted at multiple street locations on various days/times or through referral during the Fall of 2001.

RESULTS

Sixty-one percent (349/573) had heard of N-9, of which 55% (192/349) reported hearing in the prior year that N-9 may not be protective against HIV. Of men aware of N-9, 83% (289/349) knowingly used it in their lifetime, of which 67% (193/289) used it during anal intercourse in the previous year. Forty-one percent (79/193) of those who used N-9 during anal intercourse in the past year did so without a condom because they thought it may protect against HIV. Older men were more likely than younger men to have used N-9 for protection. Men who heard that N-9 may not protect were less likely, and African-Americans (versus Caucasians) were more likely, to say they would definitely use N-9 during anal intercourse in the future. Latinos (versus Caucasians), those with unknown HIV serostatus (versus HIV-negative), and those with lower education were less likely to know about N-9 at all, and thus were at risk for unknowingly using N-9.

CONCLUSIONS

Many MSM used N-9 during or following public health warnings about the product. Actions (e.g., information campaigns, warning labels specific to rectal use) should be considered by communities to reduce rectal use of N-9.

Sexually Transmitted Diseases in Men Who Have Sex with Men: An Epidemiologic Review

The introduction of highly active antiretroviral therapy (HAART) has led to dramatic reductions in morbidity and mortality due to HIV infection. However, the resulting optimism and improved health status produced by HAART appears to have contributed to unanticipated consequences in men who have sex with men (MSM): loss of fear of acquiring and transmitting HIV, an increase in high-risk sex, decreased use of condoms, and a resurgence of gonorrhea and syphilis. Other factors, such as lack of knowledge of sexually transmitted diseases (STDs), use of the Internet as a venue to find sex partners, the increasing use of Viagra (Pfizer, New York, NY) as a recreational drug, and the apparent expanding role of oral sex in STD transmission are fueling these trends. Since ulcerative and inflammatory STDs facilitate HIV transmission, a new wave of HIV infection in MSM may be on the horizon. The rising STD rates and relapses in high-risk sexual behaviors in MSM, both HIV-infected and -uninfected MSM, have profound implications for public health and the clinical management of these patients. Clinicians should be aware of this turn of events, and implement new screening and counseling guidelines that have been issued in response to these alarming reports.

Public policy regulating private and public space in gay bathhouses

Public policies prohibiting either public or private space in gay bathhouses vary across cities. New York, San Francisco, Los Angeles, and Chicago all have different policies. The objective of this study was to assess reported risk behavior as an indicator of success of one policy over another. Data are from a telephone survey of a probability sample of men living in the four cities who reported having sex with men. Analyses focused on city differences in behavior of adult men who, in the past year, were sexually active with a male and visited a bathhouse ( n= 827). Respondents reported numbers of sex partners, one-night stands, visits to bathhouses in the past year, and casual sex partners with whom they had engaged in unprotected anal intercourse (UAI) as well as whether they had UAI in a public setting. Among men who visit bathhouses, no significant city differences were observed except that there were city differences in where UAI occurred-i.e., San Francisco men were significantly less likely to report UAI in a public place than were men in other cities. The data suggest that different city policies may affect where, but not whether, UAI occurs.

Determinants of human immunodeficiency virus (HIV) prevalence in homosexual and bisexual men screened for admission to a cohort study of HIV negatives in Belo Horizonte, Brazil: Project Horizonte

Project Horizonte, an open cohort of homosexual and bisexual human immunodeficiency virus (HIV-1) negative men, is a component of the AIDS Vaccine Program, in Belo Horizonte, Minas Gerais, Brazil. The objective of this study was to compare volunteers testing HIV positive at cohort entry with a sample of those who tested HIV negative in order to identify risk factors for prevalent HIV infection, in a population being screened for enrollment at Project Horizonte. A nested case-control study was conducted. HIV positive volunteers at entry (cases) were matched by age and admission date to three HIV negative controls each. Selected variables used for the current analysis included demographic factors, sexual behavior and other risk factors for HIV infection. During the study period (1994-2001), among the 621 volunteers screened, 61 tested positive for HIV. Cases were matched to 183 HIV negative control subjects. After adjustments, the main risk factors associated with HIV infection were unprotected sex with an occasional partners, OR = 3.7 (CI 95% 1.3-10.6), receptive anal intercourse with an occasional partner, OR = 2.8 (95% CI 0.9-8.9) and belonging to the negro racial group, OR = 3.4 (CI 95% 1.1-11.9). These variables were associated with an increase in the risk of HIV infection among men who have sex with men at the screening for admission to an open HIV negative cohort.

Viral load and HIV treatment attitudes as correlates of sexual risk behavior among HIV-positive gay men

OBJECTIVES

People living with HIV who achieve an "undetectable" viral load may assume that they are less infectious, leading to increased sexual risk. We examined the relation between perceiving that one has an undetectable viral load and sexual risk taking among gay men.

METHODS

HIV-positive participants (N=60) completed measures assessing HIV serostatus, perceived HIV viral load (detectable vs. undetectable), sexual risk and treatment attitudes.

RESULTS

Contrary to hypotheses, HIV-positive men with detectable viral loads were more likely to report unprotected anal sex with a nonprimary partner than were men reporting undetectable viral loads. Although a significant minority endorsed the belief that an HIV-positive partner with an undetectable viral load is less infectious, this belief was unrelated to sexual risk. Multivariate analyses showed that the strongest predictor of sexual risk was a measure assessing participants' reduced concern over HIV stemming from the availability of improved HIV treatments. After controlling for reduced HIV concern, viral load status was no longer a significant predictor of risk.

CONCLUSIONS

Results suggest that reduced concern about the consequences of HIV infection may be more important than perceived health status as a determinant of risky sex and highlight the need for continued prevention efforts among people who are HIV-positive.

Age and race mixing patterns of sexual partnerships among Asian men who have sex with men: implications for HIV transmission and prevention

Recent studies of U.S. men who have sex with men (MSM) have reported high rates of unprotected anal intercourse but low rates of HIV infection among Asian and Pacific Islander (API) men. We investigated this discrepancy by examining the characteristics of sexual partnerships among API MSM. Multivariate logistic regression analyses found that having an API partner was related to having unprotected anal intercourse after controlling for respondent's age, number of sexual partners, and partner type. Having an API partner and a younger partner were related to respondent reports of unprotected insertive anal intercourse. However, a partner's race and age did not predict unprotected receptive anal intercourse. Study findings suggest that HIV prevalence among API MSM may have remained relatively low because higher risk sexual practices occur more frequently within a lower risk API group compared with higher risk non-API groups. However, because the possibility for the rise of HV infection in this population still exists if HIV spreads from older to younger men, HIV prevention efforts must target partner characteristics to maintain low HIV prevalence among API MSM.

Sexually transmitted diseases surveillance among incarcerated men who have sex with men--an opportunity for HIV prevention

There is an urgent need for behavioral surveillance and prevention strategies specifically designed for men who have sex with men (MSM) who exhibit high-risk behavior. This report describes a sentinel screening program designed to identify sexually transmitted infections among incarcerated MSM. Approximately 2,200 inmates were screened for HIV, syphilis, gonorrhea, and chlamydia from a segregated unit of men who have sex with men in Los Angeles County Men's Central Jail. A convenience sample of 217 participants was offered a survey to assess risk behaviors. Screening activities yielded a 12.4% HIV, 3.1% chlamydia, 1.5% gonorrhea, and 0.3% early syphilis prevalence. The high HIV prevalence found in this population indicates the opportunity for HIV prevention within sexually transmitted disease (STD) screening of incarcerated MSM. Bridging HIV prevention into STD screening will require the integration of primary and secondary prevention services within the jail including case management, early treatment, and referral services.

The effect of partner characteristics on HIV infection among African American men who have sex with men in the Young Men's Survey, Los Angeles, 1999-2000

Previous studies have documented disparities in HIV prevalence by race among men who have sex with men (MSM), even after adjusting for traditional risk factors. In this analysis of data collected for the 1999-2000 Los Angeles Young Men's Survey, a cross-sectional venue-based survey of MSM aged 23-29, we investigated whether information on male sex-partner characteristics accounts for some of the racial/ethnic differences in HIV prevalence. In this sample of survey participants, we observed that African American MSM reported similar or lower levels of HIV risk behaviors compared with White MSM but much higher HIV prevalence (26% vs. 7.4%, respectively). In an unadjusted logistic regression model, African American participants had 4.4 times higher odds of HIV infection compared with White participants. In a multiple logistic regression model adjusting for participant behaviors, we observed elevation of the relative odds of HIV infection for African Americans compared with Whites (odds ratio [OR] = 6.9, 95% confidence limits [CL] = 2.5, 19). In a fully adjusted model, controlling for the effects of having older partners and more African American partners, we observed a 20% reduction in the relative odds of HIV for African American participants compared with White participants (OR = 5.5, 95% CL = 1.8, 17). Our findings suggest that differences in male partner types, namely older and African American partners, may account for some of the observed racial disparity in HIV infection, especially for African American MSM compared with White MSM in Los Angeles.

Motivational, ethical, and epistemological foundations in the treatment of unwanted homoerotic attraction

A recent special section of the Journal of Marital and Family Therapy (October, 2000) focusing on the mental health needs of gay, lesbian, and bisexual individuals neglected to address the clinical needs of homosexual persons who desire to increase their heterosexual potential. This article attempts to correct this omission by outlining common motivations for pursuing change, updating the current state of knowledge regarding the effectiveness of change efforts, and providing some ethical guidelines when therapists encounter clients who present with unwanted homoerotic attraction. Finally, to assist marriage and family therapists (MFTs) in more deeply understanding divergent perspectives about reorientation treatments, an examination of the role of moral epistemology is presented and some examples of its potential influence are described. MFTs are encouraged to recognize and accept, rather than ignore or deny the valid needs of clients who seek to modify their same-sex attraction.
