Potential Contributions of Clinical and Community Testing in Identifying Persons with Undiagnosed HIV Infection in the United States

BACKGROUND

An estimated 166,155 individuals in the United States have undiagnosed HIV infection. We modeled the numbers of HIV-infected individuals who could be diagnosed in clinical and community settings by broadly implementing HIV screening guidelines.

SETTING

United States.

METHODS

We modeled testing for general population (once lifetime) and high-risk populations (annual): men who have sex with men, people who inject drugs, and high-risk heterosexuals. We used published data on HIV infections, HIV testing, engagement in clinical care, and risk status disclosure.

RESULTS

In clinical settings, about 76 million never-tested low-risk and 2.6 million high-risk individuals would be tested, yielding 36,000 and 55,000 HIV diagnoses, respectively. In community settings, 30 million low-risk and 4.4 million high-risk individuals would be tested, yielding 75,000 HIV diagnoses.

CONCLUSION

HIV testing in clinical and community settings diagnoses similar numbers of individuals. Lifetime and risk-based testing are both needed to substantially reduce undiagnosed HIV.

HIV-Related Risk Behaviors Among Male High School Students Who Had Sexual Contact with Males - 17 Large Urban School Districts, United States, 2009-2013

Young persons aged 13-24 years accounted for an estimated 22% of all new diagnoses of human immunodeficiency virus (HIV) infection in the United States in 2014. Most new HIV diagnoses among youths occur among males who have sex with males (MSM). Among all MSM, young black MSM accounted for the largest number of new HIV diagnoses in 2014 (1). To determine whether the prevalence of HIV-related risk behaviors among black male high school students who had sexual contact with males differed from the prevalence among white and Hispanic male students who had sexual contact with males, potentially contributing to the racial/ethnic disparities in new HIV diagnoses, CDC analyzed data from Youth Risk Behavior Surveys conducted by 17 large urban school districts during 2009-2013. Although other studies have examined HIV-related risk behaviors among MSM (2,3), less is known about MSM aged <18 years. Black male students who had sexual contact with males had a lower or similar prevalence of most HIV-related risk behaviors than did white and Hispanic male students who had sexual contact with males. These findings highlight the need to increase access to effective HIV prevention strategies for all young MSM.

Vital Signs: Estimated Percentages and Numbers of Adults with Indications for Preexposure Prophylaxis to Prevent HIV Acquisition--United States, 2015

BACKGROUND

In 2014, approximately 40,000 persons in the United States received a diagnosis of human immunodeficiency virus (HIV) infection. Preexposure prophylaxis (PrEP) with daily oral antiretroviral medication is a new, highly effective intervention that could reduce the number of new HIV infections.

METHODS

CDC analyzed nationally representative data to estimate the percentages and numbers of persons in the United States, by transmission risk group, with indications for PrEP consistent with the 2014 U.S. Public Health Service's PrEP clinical practice guideline.

RESULTS

Approximately 24.7% of sexually active adult men who have sex with men (MSM) (492,000 [95% confidence interval {CI} = 212,000-772,000]), 18.5% of persons who inject drugs (115,000 [CI = 45,000-185,000]), and 0.4% of heterosexually active adults (624,000 [CI = 404,000-846,000]), had substantial risks for acquiring HIV consistent with PrEP indications.

CONCLUSIONS

Based on current guidelines, many MSM, persons who inject drugs, and heterosexually active adults have indications for PrEP. A higher percentage of MSM and persons who inject drugs have indications for PrEP than heterosexually active adults, consistent with distribution of new HIV diagnoses across these populations.

IMPLICATIONS FOR PUBLIC HEALTH PRACTICE

Clinical organizations, health departments, and community-based organizations should raise awareness of PrEP among persons with substantial risk for acquiring HIV infection and their health care providers. These data can be used to inform scale-up and evaluation of PrEP coverage. Increasing delivery of PrEP and other highly effective HIV prevention services could lower the number of new HIV infections occurring in the United States each year.

Rectal application of a highly osmolar personal lubricant in a macaque model induces acute cytotoxicity but does not increase risk of SHIV infection

Background

Personal lubricant use is common during anal intercourse. Some water-based products with high osmolality and low pH can damage genital and rectal tissues, and the polymer polyquaternium 15 (PQ15) can enhance HIV replication in vitro. This has raised concerns that lubricants with such properties may increase STD/HIV infection risk, although in vivo evidence is scarce. We use a macaque model to evaluate rectal cytotoxicity and SHIV infection risk after use of a highly osmolar (>8,000 mOsm/kg) water-based lubricant with pH of 4.4, and containing PQ15.

Methods

Cytotoxicity was documented by measuring inflammatory cytokines and epithelial tissue sloughing during six weeks of repeated, non-traumatic lubricant or control buffer applications to rectum and anus. We measured susceptibility to SHIV_SF162P3 infection by comparing virus doses needed for rectal infection in twenty-one macaques treated with lubricant or control buffer 30 minutes prior to virus exposure.

Results

Lubricant increased pro-inflammatory cytokines and tissue sloughing while control buffer (phosphate buffered saline; PBS) did not. However, the estimated AID₅₀ (50% animal infectious dose) was not different in lubricant- and control buffer-treated macaques (p = 0.4467; logistic regression models).

Conclusions

Although the test lubricant caused acute cytotoxicity in rectal tissues, it did not increase susceptibility to infection in this macaque model. Thus neither the lubricant-induced type/extent of inflammation nor the presence of PQ15 affected infection risk. This study constitutes a first step in the in vivo evaluation of lubricants with regards to HIV transmission.

Vital Signs: HIV diagnosis, care, and treatment among persons living with HIV--United States, 2011

In the United States, an estimated 1.2 million persons are living with human immunodeficiency virus (HIV), a serious infection that, if untreated, leads to illness and premature death. Persons living with HIV who use antiretroviral therapy (ART) and achieve very low levels of the virus (suppressed viral load) can have a nearly normal life expectancy and have very low risk for transmitting HIV to others. However, each year in the United States, nearly 50,000 persons become infected with HIV. Each step along the HIV care continuum (HIV diagnosis, prompt and sustained HIV medical care, and ART) is essential for achieving a suppressed viral load.

A holistic approach to addressing HIV infection disparities in gay, bisexual, and other men who have sex with men

Gay, bisexual, and other men who have sex with men (MSM) have been disproportionately affected by HIV and AIDS since the beginning of the epidemic in the United States and in many other parts of the world. The HIV epidemic is inextricably tied to other health problems that disproportionately affect gay, bisexual, and other MSM including psychological comorbidities, substance use, sexual victimization, stigmatization, and multiple forms of discrimination. These interrelated health problems and social issues can be characterized as a syndemic of mutually reinforcing conditions or epidemics. Moreover, the syndemic is directed by biological, behavioral, psychosocial, and structural determinants. Addressing HIV within the context of a larger syndemic will require a more holistic approach to HIV prevention and treatment that recognizes the interplay between biological, behavioral, psychosocial, and structural factors that affect the health and well-being of sexual minority men.

HIV testing and risk behaviors among gay, bisexual, and other men who have sex with men - United States

The burden of human immunodeficiency virus (HIV) is high among gay, bisexual, and other men who have sex with men (MSM). High HIV prevalence, lack of awareness of HIV-positive status, unprotected anal sex, and increased viral load among HIV-positive MSM not on antiretroviral treatment contribute substantially to new infections among this population. CDC analyzed data from the National HIV Surveillance System (NHSS) to estimate the percentage of HIV diagnoses among MSM by area of residence and data from the National HIV Behavioral Surveillance System (NHBS) to estimate unprotected anal sex in the past 12 months among MSM in 2005, 2008, and 2011; unprotected discordant anal sex at last sex (i.e., with a partner of opposite or unknown HIV status) in 2008 and 2011; and HIV testing history and the percentage HIV-positive but unaware of their HIV status by the time since their last HIV test in 2011. This report describes the results of these analyses. In all but two states, the majority of new HIV diagnoses were among MSM in 2011. Unprotected anal sex at least once in the past 12 months increased from 48% in 2005 to 57% in 2011 (p<0.001). The percentage engaging in unprotected discordant anal sex was 13% in 2008 and 2011. In 2011, 33% of HIV-positive but unaware MSM reported unprotected discordant anal sex. Among MSM with negative or unknown HIV status, 67% had an HIV test in the past 12 months. Among those tested recently, the percentage HIV-positive but unaware of their infection was 4%, 5%, and 7% among those tested in the past ≤3, 4-6, and 7-12 months, respectively. Expanded efforts are needed to reduce HIV risk behaviors and to promote at least annual HIV testing among MSM.

Cost-utility analysis of the housing and health intervention for homeless and unstably housed persons living with HIV

We present a cost-utility analysis based on data from the Housing and Health (H&H) Study of rental assistance for homeless and unstably housed persons living with HIV in Baltimore, Chicago and Los Angeles. As-treated analyses found favorable associations of housing with HIV viral load, emergency room use, and perceived stress (an outcome that can be quantitatively linked to quality of life). We combined these outcome data with information on intervention costs to estimate the cost-per-quality-adjusted-life-year (QALY) saved. We estimate that the cost-per-QALY-saved by the HIV-related housing services is $62,493. These services compare favorably (in terms of cost-effectiveness) to other well-accepted medical and public health services.

Estimating the impact of state budget cuts and redirection of prevention resources on the HIV epidemic in 59 California local health departments

BACKGROUND

In the wake of a national economic downturn, the state of California, in 2009-2010, implemented budget cuts that eliminated state funding of HIV prevention and testing. To mitigate the effect of these cuts remaining federal funds were redirected. This analysis estimates the impact of these budget cuts and reallocation of resources on HIV transmission and associated HIV treatment costs.

METHODS AND FINDINGS

We estimated the effect of the budget cuts and reallocation for California county health departments (excluding Los Angeles and San Francisco) on the number of individuals living with or at-risk for HIV who received HIV prevention services. We used a Bernoulli model to estimate the number of new infections that would occur each year as a result of the changes, and assigned lifetime treatment costs to those new infections. We explored the effect of redirecting federal funds to more cost-effective programs, as well as the potential effect of allocating funds proportionately by transmission category. We estimated that cutting HIV prevention resulted in 55 new infections that were associated with $20 million in lifetime treatment costs. The redirection of federal funds to more cost-effective programs averted 15 HIV infections. If HIV prevention funding were allocated proportionately to transmission categories, we estimated that HIV infections could be reduced below the number that occurred annually before the state budget cuts.

CONCLUSIONS

Reducing funding for HIV prevention may result in short-term savings at the expense of additional HIV infections and increased HIV treatment costs. Existing HIV prevention funds would likely have a greater impact on the epidemic if they were allocated to the more cost-effective programs and the populations most likely to acquire and transmit the infection.

Results from two online surveys comparing sexual risk behaviors in Hispanic, black, and white men who have sex with men

Many men who have sex with men (MSM) are among those who increasingly use the internet to find sexual partners. Few studies have compared behavior by race/ethnicity in internet-based samples of MSM. We examined the association of race/ethnicity with HIV risk-related behavior among 10,979 Hispanic, black, and white MSM recruited online. Significant variations by race/ethnicity were found in: age, income level, sexual orientation, number of lifetime male and female sexual partners, and rates of unprotected anal intercourse (UAI). Black and Hispanic men were more likely to report anal intercourse during the last sexual encounter, but white men were more likely to report UAI. In multivariate analysis, UAI was associated with HIV infection and sex with a main partner. Significant risk behavior variations by race/ethnicity were found. Research is needed to better target online interventions to MSM who engage in UAI or have other risk factors for transmitting or acquiring HIV.

Sexual health, HIV, and sexually transmitted infections among gay, bisexual, and other men who have sex with men in the United States

The sexual health of gay, bisexual, and other men who have sex with men (MSM) in the United States is not getting better despite considerable social, political and human rights advances. Instead of improving, HIV and sexually transmitted infections (STIs) remain disproportionately high among MSM and have been increasing for almost two decades. The disproportionate and worsening burden of HIV and other STIs among MSM requires an urgent re-assessment of what we have been doing as a nation to reduce these infections, how we have been doing it, and the scale of our efforts. A sexual health approach has the potential to improve our understanding of MSM's sexual behavior and relationships, reduce HIV and STI incidence, and improve the health and well-being of MSM.

Associations between substance use, sexual risk taking and HIV treatment adherence among homeless people living with HIV

Prior research suggests that the interconnections between substance use, HIV risk and lack of adherence to HIV medications are especially strong among homeless individuals. Thus, study of these interconnections warrants public health attention. The objectives of this paper are to describe patterns of alcohol and drug use, associations between substance use and participation in high-risk sex, and associations between substance use and adherence to HIV treatment regimens among a sample of 602 homeless or unstably housed HIV-seropositive individuals who are part of a housing-based intervention--the Housing and Health Study. Participants experienced high levels of substance use. Significant associations were found between substance use and adherence to HIV treatment medications, and between substance use and high-risk sexual practices within the entire group. Group analyses by sexual orientation/gender show that the association between substance use and treatment adherence is found primarily among heterosexual males whereas the relationship between several drugs and high-risk sexual practices is strongest among gay and bisexual men. Health professionals working with HIV-seropositive individuals should routinely ascertain housing status and screen for substance use and risky sex.

The effects of HIV stigma on health, disclosure of HIV status, and risk behavior of homeless and unstably housed persons living with HIV

HIV-related stigma negatively affects the lives of persons living with HIV/AIDS (PLWHA). Homeless/unstably housed PLWHA experience myriad challenges and may be particularly vulnerable to the effects of HIV-related stigma. Homeless/unstably housed PLWHA from 3 U.S. cities (N = 637) completed computer-assisted interviews that measured demographics, self-assessed physical and mental health, medical utilization, adherence, HIV disclosure, and risk behaviors. Internal and perceived external HIV stigma were assessed and combined for a total stigma score. Higher levels of stigma were experienced by women, homeless participants, those with a high school education or less, and those more recently diagnosed with HIV. Stigma was strongly associated with poorer self-assessed physical and mental health, and perceived external stigma was associated with recent non-adherence to HIV treatment. Perceived external stigma was associated with decreased HIV disclosure to social network members, and internal stigma was associated with drug use and non-disclosure to sex partners. Interventions are needed to reduce HIV-related stigma and its effects on the health of homeless/unstably housed PLWHA.

Intentional abstinence among homeless and unstably housed persons living with HIV/AIDS

Some persons living with HIV/AIDS (PLWHA) engage in periods of sexual abstinence. Baseline data from a larger study of homeless/unstably housed PLWHA indicated that 20% (125/644) intentionally abstained from sex in the past 90 days. Reasons included: (1) 'not interested' (n = 78); (2) did not want to infect someone (n = 46); and (3) did not have a partner (n = 37). Abstinence was less likely among all who had a main partner. Among men who have sex with men (MSM), abstinence was less likely among those with a detectable viral load. It was more likely among heterosexual men who were experiencing current housing problems and who had at least a high school education. Among women, abstinence was less likely among African Americans and those whose social networks were more aware of their HIV status. Better understanding of motivations to abstain may improve how programs serving PLWHA address this issue.

Summary of comments and recommendations from the CDC consultation on the HIV/AIDS Epidemic and prevention in the Hispanic/Latino community

In April 2008, the U.S. Centers for Disease Control and Prevention (CDC) hosted a national consultation meeting of academic researchers, public health officials, service providers, and community leaders to examine the HIV/AIDS epidemic and prevention needs of Hispanics/Latinos in the United States and its territories. The consultation engaged key stakeholders to review available information on HIV-related behavioral research and prevention efforts, describe gaps in current HIV prevention programs and research on Hispanics/Latinos, and identify community and societal-level factors that can increase vulnerability of Hispanics/Latinos for acquiring or transmitting HIV infection. Recommendations were also made to CDC for future collaboration with the Hispanic/Latino community in areas of HIV prevention research and prevention programs. This article summarizes participants' recommendations for HIV prevention research, program and capacity building, policy and planning, and partnerships and communication. These recommendations will be used by CDC to inform the development of a National Plan of Action for HIV/AIDS prevention among Hispanics/Latinos, and can provide a framework for use by other federal and non-federal agencies, academic researchers, community-based organizations, and policymakers as they seek to curtail the HIV epidemic among Hispanics/Latinos.

A review of the Centers for Disease Control and Prevention's response to the HIV/AIDS crisis among Blacks in the United States, 1981-2009

Among US racial/ethnic groups, Blacks are at the highest risk of acquiring HIV/AIDS. In response, the Centers for Disease Control and Prevention (CDC) has launched the Heightened National Response to Address the HIV/AIDS Crisis Among African Americans, which seeks to engage public and nonpublic partners in a synergistic effort to prevent HIV among Blacks. The CDC also recently launched Act Against AIDS, a campaign to refocus attention on the domestic HIV/AIDS crisis. Although the CDC's efforts to combat HIV/AIDS among Blacks have achieved some success, more must be done to address this crisis. New initiatives include President Obama's goal of developing a National HIV/AIDS Strategy to reduce HIV incidence, decrease HIV-related health disparities, and increase access to care, especially among Blacks and other disproportionately affected populations.

Factors associated with adherence to highly active antiretroviral therapy in homeless or unstably housed adults living with HIV

The aim of this study is to investigate adherence to highly active antiretroviral therapy (HAART) in persons living with HIV/AIDS (PLWHA) who are homeless or unstably housed. We evaluated homeless or unstably housed PLWHA (n=644) in three US cities were enrolled in the Housing and Health Study. Using baseline data and controlling for gender, race, age, and education, we examined associations between self-reported two- and Seven-day adherence and access to healthcare, mental health, substance use, and attitudes toward HIV medical therapy. Of the 644 participants, 358 (55%) were currently on HAART. For two-day adherence, 280 (78%) reported missing no prescribed doses (100% adherence), and for seven-day adherence, 291 (81%) reported > or =90% adherence. Logistic regression analyses indicated being younger, not having health insurance, and drug use were associated with missing > or =1 dose over the past two days. Scoring lower on SF-36 mental component summary scale and having greater risk of depression (CES-D) and stress (Perceived Stress Scale) were associated with poorer adherence for both two- and seven-day outcomes. Negative attitudes toward HIV treatment were also associated with lower adherence. Adherence to HIV medications in this population is similar to other groups. Coexisting problems of access to healthcare, higher risk of mental health problems, along with poorer attitudes toward treatment are associated with increased likelihood of missing doses. Comprehensive models of HIV care that include a continuum of medical and social services are essential for treating this population.

Screening for depressive symptoms in an online sample of men who have sex with men

Depression is a debilitating disorder and relatively high rates have been reported in studies of men who have sex with men (MSM). This study was undertaken to assess the utility of screening for, and characteristics associated with, depressive symptoms in an online survey of MSM. In 2003-2004, an online cross-sectional study was conducted among 2,964 MSM from the US and Canada. Using the two-item Patient Health Questionnaire (PHQ-2), 18% of the study participants screened positive for depressive symptoms within the past three months. Characteristics associated with a positive PHQ-2 screen for depressive symptoms in multivariate analysis included: having less than a high school or college degree; being single (not having a primary male partner) or being married to a woman; being HIV-positive; and not having recent sex. Additionally, among men who screened positive on the PHQ-2, predictors of not having treatment from a mental health provider in the past year were: low education; being black/African American/Canadian or Hispanic; and having no primary care provider. The Internet is a viable medium to reach and screen men at-risk for depression. Future work is needed for online outreach and connection to offline assessment as well as intervention.

Meta-analysis of cognitive-behavioral interventions on HIV-positive persons' mental health and immune functioning

OBJECTIVE

To evaluate the efficacy of cognitive-behavioral interventions (CBIs) for improving the mental health and immune functioning of people living with HIV (PLWH).

DESIGN

Comprehensive searches of electronic databases from 1988 to 2005, hand searches of journals, reference lists of articles, and contacts with researchers. Meta-analytic approaches were used in synthesizing findings.

MAIN OUTCOME MEASURES

Intervention effects on symptoms of depression, anxiety, and anger, stress, and CD4 cell counts were assessed.

RESULTS

Data from 15 controlled trials were analyzed. Significant intervention effects were observed for improving symptoms of depression (d = 0.33), anxiety (d = 0.30), anger (d = 1.00), and stress (d = 0.43). There is limited evidence suggesting intervention effects on CD4 cell counts (d = 0.08). The aggregated effect size estimates for depression and anxiety were statistically significant in trials that provided stress management skills training and had more than 10 intervention sessions.

CONCLUSION

CBIs are efficacious in improving various psychological states of PLWH. Future research should examine the relationship among interventions, psychological states, medication adherence, and immune functions, and identify other relevant factors associated with intervention effects.

HIV, homelessness, and public health: critical issues and a call for increased action

Homelessness and housing instability are significant public health issues that increase the risks of HIV acquisition and transmission and adversely affect the health of people living with HIV. This article highlights the contributions of selected papers in this special issue of AIDS and Behavior and considers them within the broader context of prior research on the associations between housing status and HIV risk, use of HIV medical care, adherence to HIV treatment, and the physical health of HIV-seropositive persons. Special recognition is given to the roles of interrelated health problems, such as substance abuse, poor mental health, and physical and sexual abuse, that often co-occur and exacerbate the challenges faced by those who are homeless or unstably housed. Taken as a whole, the findings indicate a critical need for public health programs to develop strategies that address the fundamental causes of HIV risk among homeless and unstably housed persons and, for those living with HIV, contribute to their risk of disease progression. Such strategies should include "mid-stream" and "upstream" approaches that address the underlying causes of these risks. The successful implementation of these strategies will require leadership and the formation of new partnerships on the part of public health agencies. Such efforts, however, may have significant effects on the individuals and communities most affected by HIV/AIDS.

Cost and threshold analysis of housing as an HIV prevention intervention

The Housing and Health study examines the effects of permanent supportive housing for homeless and unstably housed persons living with HIV. While promising as an HIV prevention intervention, providing housing may be more expensive to deliver than some other HIV prevention services. Economic evaluation is needed to determine if investment in permanent supportive housing would be cost-saving or cost-effective. Here we ask -- what is the per client cost of delivering the intervention, and how many HIV transmissions have to be averted in order to exceed the threshold needed to claim cost-savings or cost-effectiveness to society? Standard methods of cost and threshold analysis were employed. Payor perspective costs range from $9,256 to $11,651 per client per year; societal perspective costs range from $10,048 to $14,032 per client per year. Considering that averting a new case of HIV saves an estimated $221,365 in treatment costs, the average cost-saving threshold across the three study cities is 0.0555. Expressed another way, if just one out of every 19 Housing & Health intervention clients avoided HIV transmission to an HIV seronegative partner the intervention would be cost-saving. The intervention would be cost-effective if it prevented just one HIV transmission for every 64 clients served.

Access to housing as a structural intervention for homeless and unstably housed people living with HIV: rationale, methods, and implementation of the housing and health study

Homelessness and unstable housing have been associated with HIV risk behavior and poorer health among persons living with HIV/AIDS (PLWHA), yet prior research has not tested causal associations. This paper describes the challenges, methods, and baseline sample of the Housing and Health Study, a longitudinal, multi-site, randomized controlled trial investigating the effects of providing immediate rental housing assistance to PLWHA who were homeless or at severe risk of homelessness. Primary outcomes included HIV disease progression, medical care access and utilization, treatment adherence, mental and physical health, and risks of transmitting HIV. Across three study sites, 630 participants completed baseline sessions and were randomized to receive either immediate rental housing assistance (treatment group) or assistance finding housing according to local standard practice (comparison group). Baseline sessions included a questionnaire, a two-session HIV risk-reduction counseling intervention, and blood sample collection to measure CD4 counts and viral load levels. Three follow-up visits occurred at 6, 12, and 18 months after baseline. Participants were mostly male, Black, unmarried, low-income, and nearly half were between 40 and 49 years old. At 18 months, 84% of the baseline sample was retained. The retention rates demonstrate the feasibility of conducting scientifically rigorous housing research, and the baseline results provide important information regarding characteristics of this understudied population that can inform future HIV prevention and treatment efforts.

Physical and sexual abuse among homeless and unstably housed adults living with HIV: prevalence and associated risks

We examined the prevalence and risks associated with interpersonal (physical and sexual) abuse among HIV-seropositive homeless or unstably housed adults. Data were obtained from the Housing and Health Study of participants living in Baltimore, Chicago, and Los Angeles (n = 644). We used logistic regression to identify risks associated with abuse. About 77% of men and 86% of women reported ever experiencing abuse. Women were at greater risk than men for intimate partner physical abuse, childhood sexual abuse (CSA), and adulthood sexual abuse. Men and women experiencing intimate partner physical abuse reported increased risk of unprotected sex. Other risks associated with abuse include sex exchange; lifetime alcohol abuse; and depressive symptoms. Abuse prevalence among sample exceeds those found in other samples of general USA, HIV-seropositive, and homeless populations. Identifying persons at risk of abuse is needed to reduce risk among homeless or unstably housed persons living with HIV.

Health status, health care use, medication use, and medication adherence among homeless and housed people living with HIV/AIDS

OBJECTIVES

We sought to compare health status, health care use, HIV anti-retroviral medication use, and HIV medication adherence among homeless and housed people with HIV/AIDS.

METHODS

Data were obtained from a cross-sectional, multisite behavioral survey of adults (N=7925) recently reported to be HIV positive.

RESULTS

At the time interviews were conducted, 304 respondents (4%) were homeless. Self-ratings of mental, physical, and overall health revealed that the health status of homeless respondents was poorer than that of housed respondents. Also, homeless respondents were more likely to be uninsured, to have visited an emergency department, and to have been admitted to a hospital. Homeless respondents had lower CD4 counts, were less likely to have taken HIV anti-retroviral medications, and were less adherent to their medication regimen. Homeless respondents needed more HIV social and medical services, but nearly all respondents in both groups had received needed services. Housing status remained a significant predictor of health and medication outcomes after we controlled for potential confounding variables.

CONCLUSIONS

Homeless people with HIV/AIDS are at increased risk of negative health outcomes, and housing is a potentially important mechanism for improving the health of this vulnerable group.

Beliefs about personal and partner responsibility among HIV-seropositive men who have sex with men: measurement and association with transmission risk behavior

Beliefs of people living with HIV about their own responsibility for preventing HIV transmission (personal responsibility) and their sex partners' responsibility for protecting themselves (partner responsibility) are poorly understood. A sample of 1163 HIV-seropositive men who have sex with men (MSM; 55% men of color) completed an A-CASI assessment of sexual behavior and psychosocial measures. A two-dimensional model that represents four orientations toward responsibility was tested: (1) self-high personal and low partner responsibility, (2) other-low personal and high partner responsibility, (3) shared-high personal and high partner responsibility, and (4) diminished-low personal and low partner responsibility. As predicted, the self-responsibility group demonstrated the lowest risk of HIV transmission; the other responsibility group had the highest risk. Intermediate risk was observed in the shared and diminished responsibility groups. Implications for future research and HIV prevention efforts are discussed.

A comparison of on-line and off-line sexual risk in men who have sex with men: an event-based on-line survey

OBJECTIVE

To assess whether men who have sex with men (MSM) are more likely to report unprotected anal intercourse (UAI) with partners met on-line compared with those met off-line.

METHODS

A total of 6122 individuals consented to participate in an anonymous behavioral survey on-line. This event-based analysis is limited to the 1683 men from the United States and Canada who had sex in the 3 months before the study and reported that their last sexual encounter included a new or casual male partner or partners. Prevalence and predictors of UAI were analyzed separately for the 386 men reporting more than 1 partner (multiple) and the 1297 men reporting only 1 (single) partner in their last encounter.

RESULTS

Of the 1683 MSM recruited on-line, 51% met their partner(s) in their last sexual encounter on-line and 23% reported UAI. No difference in risk for UAI was found for partners met on-line versus off-line in the bivariate or multivariate analyses. In a multivariate analysis of men with multiple-partner encounters, UAI was significantly associated with being HIV-seropositive (adjusted odds ratio [OR] = 2.87; P = 0.02) in a model that included age; education; whether partners were met on-line or off-line; and use of crystal methamphetamine, sildenafil, or alcohol before sex. Using the same model, significant predictors of UAI in men reporting a single-partner encounter were use of crystal methamphetamine (adjusted OR = 5.67; P = 0.001) and no college degree (adjusted OR = 1.63; P = 0.01).

CONCLUSIONS

MSM recruited on-line who reported a new or casual sex partner(s) in the prior 3 months are at considerable risk of HIV or other sexually transmitted infections, but they are equally likely to report UAI whether sex partners were met on-line or off-line. The Internet may be an ideal venue for reaching high-risk MSM.

Relative efficacy of a multisession sexual risk-reduction intervention for young men released from prisons in 4 states

OBJECTIVES

We compared the effects of an enhanced multisession intervention with a single-session intervention on the sexual risk behavior of young men released from prison.

METHODS

Young men, aged 18 to 29 years, were recruited from US prisons in 4 states and systematically assigned to the prerelease single-session intervention or the pre- and postrelease enhanced intervention. Both interventions addressed HIV, hepatitis, and other sexually transmitted infections; the enhanced intervention also addressed community reentry needs (e.g., housing, employment). Assessment data were collected before intervention, and 1, 12, and 24 weeks after release.

RESULTS

A total of 522 men were included in intent-to-treat analyses. Follow-up rates ranged from 76% to 87%. Unprotected vaginal or anal sex during the 90 days before incarceration was reported by 86% of men in the enhanced intervention and 89% in the single-session intervention (OR=0.78; 95% CI=0.46, 1.32). At 24 weeks, 68% of men assigned to the enhanced intervention reported unprotected vaginal or anal sex compared with 78% of those assigned to the single-session intervention (OR=0.40; 95% CI=0.18, 0.88).

CONCLUSION

Project START demonstrated the efficacy of a sexual risk-reduction intervention that bridges incarceration and community reentry.

Self-identification as "down low" among men who have sex with men (MSM) from 12 US cities

Men who have sex with men (MSM) who are on the "down low" (DL) have been the subject of considerable media attention, but few data on this population exist. This exploratory study (N=455) compared MSM who considered themselves to be on the DL with MSM who did not (non-DL MSM). 20% self-identified as DL. Blacks and Hispanics were more likely than Whites to self identify as DL. MSM who did not identify as gay were more likely than gay-identified MSM to describe themselves as DL. DL-identified MSM were less likely to have had seven or more male partners in the prior 30 days, but were more likely to have had a female sex partner and to have had unprotected vaginal sex. DL-identified MSM were less likely to have ever been tested for HIV than were non-DL MSM. Prevention agencies should expand existing programs for MSM to include specific efforts to reach DL MSM.

Greater risk for HIV infection of black men who have sex with men: a critical literature review

HIV rates are disproportionately higher for Black men who have sex with men (MSM) than for other MSM. We reviewed the literature to examine 12 hypotheses that might explain this disparity. We found that high rates of HIV infection for Black MSM were partly attributable to a high prevalence of sexually transmitted diseases that facilitate HIV transmission and to undetected or late diagnosis of HIV infection; they were not attributable to a higher frequency of risky sexual behavior, nongay identity, or sexual nondisclosure, or to reported use of alcohol or illicit substances. Evidence was insufficient to evaluate the remaining hypotheses.Future studies must address these hypotheses to provide additional explanations for the greater prevalence of HIV infection among Black MSM.

Is HIV/AIDS stigma dividing the gay community? Perceptions of HIV-positive men who have sex with men

Stigma surrounding HIV/AIDS has existed since the beginning of the epidemic, but little is known about HIV/AIDS stigma within the gay community and how it affects men who have sex with men (MSM) living with HIV. A better understanding of the effects of stigma on this population is needed to reduce it and its harmful effects. Our study used quantitative data from 206 HIV-positive MSM and qualitative data from 250 to document beliefs about HIV/AIDS stigma within the gay community and to measure its effects on sexual risk behaviors, substance use behaviors, serostatus disclosure, and mental health. Stigma was associated with increased levels of anxiety, loneliness, depressive symptoms, engaging in avoidant coping strategies, and history of suicidal ideation. HIV/AIDS stigma exists within the gay community and has a negative effect on the mental health of people living with HIV. HIV/AIDS stigma should be monitored closely so that we may better understand how to address it.

Do prevention interventions reduce HIV risk behaviours among people living with HIV? A meta-analytic review of controlled trials

OBJECTIVE

To conduct a meta-analytic review of HIV interventions for people living with HIV (PLWH) to determine their overall efficacy in reducing HIV risk behaviours and identify intervention characteristics associated with efficacy.

METHODS

Comprehensive searches included electronic databases from 1988 to 2004, hand searches of journals, reference lists of articles, and contacts with researchers. Twelve trials met the stringent selection criteria: randomization or assignment with minimal bias, use of statistical analysis, and assessment of HIV-related behavioural or biologic outcomes at least 3 months after the intervention. Random-effects models were used to aggregate data.

RESULTS

Interventions significantly reduced unprotected sex [odds ratio (OR), 0.57; 95% confidence interval (CI) 0.40-0.82] and decreased acquisition of sexually transmitted diseases (OR, 0.20; 95% CI, 0.05-0.73). Non-significant intervention effects were observed for needle sharing (OR, 0.47, 95% CI, 0.13-1.71). As a whole, interventions with the following characteristics significantly reduced sexual risk behaviours: (1) based on behavioural theory; (2) designed to change specifically HIV transmission risk behaviours; (3) delivered by health-care providers or counsellors; (4) delivered to individuals; (5) delivered in an intensive manner; (6) delivered in settings where PLWH receive routine services or medical care; (7) provided skills building, or (8) addressed a myriad of issues related to mental health, medication adherence, and HIV risk behaviour.

CONCLUSION

Interventions targeting PWLH are efficacious in reducing unprotected sex and acquisition of sexually transmitted diseases. Efficacious strategies identified in this review should be incorporated into community HIV prevention efforts and further evaluated for effectiveness.

Prevention with HIV-seropositive men who have sex with men: lessons from the Seropositive Urban Men's Study (SUMS) and the Seropositive Urban Men's Intervention Trial (SUMIT)

SUMMARY

Men who have sex with men (MSM) are disproportionately affected by HIV, and HIV-seropositive (HIV-positive) MSM are an especially important group for prevention efforts. This article describes findings from the Seropositive Urban Men's Study (SUMS, N = 456) and the Seropositive Urban Men's Intervention Trial (SUMIT, N = 1168). These studies were conducted from 1996 to 2002 with racially diverse samples from New York and San Francisco. Patterns of sexual behavior often reflected an understanding of the relative risks of specific sexual practices and were generally consistent with harm reduction strategies to reduce the risk of HIV transmission to uninfected partners. Some men, however, continued to engage in behaviors that placed themselves and their partners at risk for exposure to HIV and other sexually transmitted infections. Correlates of unprotected sex included self-efficacy, personal responsibility, substance use, mental health, and contextual influences. Disclosure of HIV status was a difficult issue for many HIV-positive MSM. Most participants had disclosed to their main partner, but they disclosed to less than half of their non-main partners before first sex. The interest of HIV-positive MSM in prevention efforts, the design of the SUMIT intervention trial, and implications for future research and programmatic efforts are discussed.

Risk Perception and sexual risk behaviors among HIV-positive men on antiretroviral therapy

There are reports of increased sexual risk behavior among people on highly active antiretroviral therapy (HAART) due to beliefs about risk of HIV transmission when on HAART. In a cross-sectional study (Seropositive Urban Men's Study), we examined the relationship between risk perception and sexual risk behavior among sexually active, culturally diverse HIV positive men who have sex with men (N = 456). Less than twenty-five percent engaged in unprotected anal sex (either with an HIV negative, or unknown-status partner, or an HIV positive partner) within the past 3 months. Most men believed there was significant health risk (to partner or self) associated with unprotected sex when on HAART. There was no increased risk behavior associated with being on HAART, although the perception of negative health consequences, including HIV transmission, when on HAART was significantly lower for the relatively small subset of men who reported unprotected sex. Prevention strategies need to be tailored to address risk perception associated with HAART.

Partner awareness of the serostatus of HIV-seropositive men who have sex with men: impact on unprotected sexual behavior

Prior research has provided conflicting evidence about the association between partner awareness of an HIV-seropositive person's serostatus and HIV transmission behavior via unprotected intercourse. The current study examined partner awareness of participant HIV-seropositive status and sexual behavior in a multiethnic sample of HIV-seropositive men who have sex with men. Most HIV-seropositive men reported that their primary partners are aware, and most reported that at least some non-primary partners are aware the participant was HIV-seropositive before first having sex. Partner awareness of participant HIV-serostatus was related to unprotected sexual behavior during the past 3 months in a non-linear fashion, as men with partners who were inconsistently aware had higher rates of unprotected receptive anal intercourse than men with partners who were consistently aware or consistently unaware. Men with partners who were inconsistently aware also had higher rates of insertive oral intercourse than men with partners who were consistently aware. However, there were no differences in HIV transmission risk behavior between men with partners who were consistently aware and men with partners who were consistently unaware a participant was HIV-seropositive.

Sexual harm reduction practices of HIV-seropositive gay and bisexual men: serosorting, strategic positioning, and withdrawal before ejaculation

OBJECTIVE

This study assessed unprotected anal and oral sex behaviors of HIV-positive gay and bisexual men in New York City and San Francisco with their main and non-main sexual partners. Here we focus on the use of three harm reduction strategies (serosorting, strategic positioning, and withdrawal before ejaculation) in order to decrease transmission risk.

METHOD

The data from a baseline assessment of 1168 HIV-positive gay and bisexual men in the two cities were utilized. Men were recruited from a variety of community-based venues, through advertising and other techniques.

RESULTS

City differences were identified, with more men in San Francisco reporting sexual risk behaviors across all partner types compared with men in New York City. Serosorting was identified, with men reporting significantly more oral and anal sex acts with other HIV-positive partners than with HIV-negative partners. However, men also reported more unprotected sex with partners of unknown status compared with their other partners. Some evidence of strategic positioning was identified, although differences were noted across cities and across different types of partners. Men in both cities reported more acts of oral sex without ejaculation than with ejaculation, but the use of withdrawal as a harm reduction strategy for anal sex was more common among men from San Francisco.

CONCLUSION

Overall, evidence for harm reduction was identified; however, significant differences across the two cities were found. The complicated nature of the sexual practices of gay and bisexual men are discussed, and the findings have important implications for prevention efforts and future research studies.

Barebacking identity among HIV-positive gay and bisexual men: demographic, psychological, and behavioral correlates

OBJECTIVES

To determine the correlates associated with barebacking identity among HIV-positive gay and bisexual men.

DESIGN

An analysis of data from the baseline quantitative assessment of a randomized controlled intervention study of 1168 HIV-positive gay and bisexual men from New York City and San Francisco.

METHODS

Participants were actively and passively recruited from mainstream gay venues, AIDS service organizations, and public and commercial sex environments. Participants completed a computerized quantitative questionnaire assessing their identity as a barebacker, sexual behavior, demographic factors, psychosocial states, perceptions of health risks, and substance use.

RESULTS

Men of color were less likely to identify themselves as barebackers. Men who did identify themselves as barebackers were slightly younger. They were more likely to miss a dose of medication; report drug use (non-injection and injection); exhibit higher levels of sexual compulsivity and lower personal responsibility for safer sex; and report higher rates of unprotected insertive anal intercourse, unprotected receptive anal intercourse, and unprotected insertive oral intercourse with all partners, regardless of their HIV serostatus.

CONCLUSION

Barebacking and its corresponding behaviors pose immediate public health risks for HIV-positive gay and bisexual men. Further work is needed to understand this phenomenon more fully in relation to the psychological, sociological, biomedical, and cultural realities.

Consistent, inconsistent, and non-disclosure to casual sexual partners among HIV-seropositive gay and bisexual men

OBJECTIVE

This study examined the disclosure of HIV status to casual sex partners, factors related to disclosure, and the relationship between disclosure and HIV sexual risk behaviors among a sample of HIV-positive gay and bisexual men in New York City and San Francisco. Comparisons were made particularly among men who reported consistent disclosure, inconsistent disclosure, and non-disclosure.

METHOD

The data from a baseline assessment of 1168 HIV-positive gay and bisexual men in the two cities were utilized. Men were recruited from a variety of community-based venues, through advertising, and other techniques.

RESULTS

Consistent disclosers reported greater self-efficacy for disclosing and more intentions to disclose than other men. They also reported less drug use, lower incomes, and more perceived viral consequences resulting from unsafe sex than did inconsistent disclosers. Overall, sexual risk behaviors were greater among inconsistent disclosers, followed by non-disclosers, with consistent disclosers reporting the fewest HIV sexual risk behaviors.

CONCLUSION

Disclosure is not an all-or-nothing process, as evidenced by the 38% of men in the sample who reported disclosing to some, but not all, of their casual sexual partners. These inconsistent disclosers, who reported the most sexual risk practices, seem to lack strategies to deal with disclosure and risky sex. Some men who never disclose appear to have been able to adopt strategies by which they do not engage in sexual risk with casual partners. Interventions to improve self-efficacy for disclosure and help HIV-positive gay and bisexual men to identify and adopt specific strategies to address disclosure and safe sex are needed.

Effects of a peer-led behavioral intervention to reduce HIV transmission and promote serostatus disclosure among HIV-seropositive gay and bisexual men

OBJECTIVES

To evaluate the effects of an enhanced peer-led intervention on transmission risk behavior and serostatus disclosure of HIV-seropositive gay and bisexual men.

DESIGN

A randomized intervention trial.

METHODS

HIV-seropositive gay and bisexual men were recruited from New York City and San Francisco and were randomly assigned to either a standard or an enhanced intervention. The standard intervention consisted of one session that provided safer sex information. The enhanced intervention consisted of six sessions and included safer sex information, interactive learning activities, and discussion groups that were facilitated by HIV-seropositive peers. Participants completed audio computer-assisted self interview (A-CASI) assessments at baseline and 3 and 6-month follow-ups. Optional testing for sexually transmitted infections was offered at baseline and the 6-month follow-up.

RESULTS

A total of 811 participants met the inclusion criteria for outcome analyses. Of these, 85 and 90% were retained for the 3 and 6-month follow-ups, respectively. Compared with the standard intervention, fewer men assigned to the enhanced intervention reported unprotected receptive anal intercourse with a negative or unknown-serostatus partner at 3 months (21 versus 26%, P < 0.05). However, there were no other significant differences in transmission risk or serostatus disclosure at 3 or 6 months.

CONCLUSION

The enhanced intervention was associated with only a limited reduction in transmission risk at 3 months relative to the standard intervention. The characteristics of the intervention that may have reduced its efficacy are identified and directions for future research are suggested.

Psychosocial correlates of transmission risk behavior among HIV-seropositive gay and bisexual men

OBJECTIVES

We sought to identify the determinants of sexual transmission risk behavior by HIV-positive individuals. We examined social cognitive theory (SCT) variables, which have been found to mediate the effectiveness of HIV risk reduction interventions. We also sought to identify contextual influences that might contribute to initial levels of SCT factors such as self-efficacy.

METHOD

In the present study, a series of social cognitive variables and a number of factors hypothesized to influence self-efficacy were assessed among participants at baseline in the Seropositive Urban Men's Intervention Trial. Variables tested for their effects on self-efficacy included hedonistic and self-evaluative outcome expectancies, sexual compulsivity, a history of childhood sexual abuse, drug use, and race. Models predicting condom use during anal sex with partners of HIV-negative or unknown status were tested separately for main partners and for non-main partners.

RESULTS

Self-efficacy was associated with condom use in both analyses. Contextual influences on condom use with main partners were fewer and operated mostly via effects on self-efficacy. Influences on condom use with non-main partners exerted both direct effects on condom use and effects mediated by self-efficacy. Drug use was predictive of condom use with non-main, but not main, partners.

DISCUSSION

The present results support the approach of addressing both standard SCT factors, and when possible contextual factors in interventions for HIV-positive men.

Prevention with gay and bisexual men living with HIV: rationale and methods of the Seropositive Urban Men's Intervention Trial (SUMIT)

OBJECTIVES

To provide a public health rationale for prevention with HIV-seropositive gay and bisexual men and to describe the methods of the Seropositive Urban Men's Intervention Trial (SUMIT).

DESIGN

A randomized intervention trial.

METHODS

Self-identified HIV-positive gay and bisexual men were recruited from community-based venues in New York City and San Francisco. Eligible participants completed an A-CASI baseline assessment, were asked to provide samples for sexually transmitted infection (STI) testing, and were randomly assigned to either a single-session intervention or a six-session enhanced intervention designed to reduce HIV transmission risk and promote serostatus disclosure. Participants who attended the first intervention session were assessed 3 and 6 months post-intervention. STI testing was offered at the 6-month assessment.

RESULTS

A total of 1168 self-identified HIV-seropositive gay and bisexual men completed the baseline assessment, and 1110 of these (95%) opted for STI testing. A total of 811 attended the first intervention session, of which 85% were assessed at 3 months and 90% were assessed at 6 months. Of those assessed at 6 months, 92% (670/729) provided a blood or urine sample for STI testing.

CONCLUSION

SUMIT demonstrates the feasibility and acceptability of prevention research with HIV-seropositive gay and bisexual men. The study provides new information about the sexual behavior, serostatus disclosure practices, and the efficacy of an intervention to reduce HIV transmission risk.

Seroconcordant sexual partnerings of HIV-seropositive men who have sex with men

OBJECTIVES

To describe the sexual behaviors of HIV-positive men with their seroconcordant partners and to determine the factors associated with unprotected anal intercourse (UAI) in these sexual partnerings.

METHODS

The data were drawn from the baseline assessment of a randomized controlled intervention study of 1168 HIV-positive men who have sex with men recruited from mainstream gay venues, AIDS service organizations, and public/commercial sex environments.

RESULTS

Of the 1168 men, 596 engaged in sexual experiences with other HIV-positive men, and 371 of the 596 (62%) practised UAI with their seroconcordant partners. Those who engaged in UAI expressed less self-evaluation with regard to their unsafe sexual practices, had higher levels of hedonism associated with unsafe sex, and were more likely both to inject recreation drugs and use methamphetamine in particular. Furthermore, these participants expressed less concern with regard to HIV re-infection, infection with other sexually transmitted infections, and the transmission of pathogens causing opportunistic infections.

CONCLUSION

Our findings suggest that at least three sets of factors predispose HIV-positive men to engage in unsafe anal sexual behaviors with their concordant partners: a decreased belief that infection with other pathogens or re-infection with HIV present health problems; less evaluation of sexual activities and behaviors; more hedonistic expectations of sex and higher levels of sexual compulsivity, as well as recreational drug use with and without sex.

Predictors of the use of viagra, testosterone, and antidepressants among HIV-seropositive gay and bisexual men

OBJECTIVE

To examine the use and correlates of the use of prescription drugs that may affect sexual behavior among HIV-positive gay and bisexual men.

METHODS

In a cross-sectional assessment of baseline data from a behavioral intervention, we recruited 1168 HIV-positive gay and bisexual men in 2000-2001 from community venues in New York City and San Francisco, and determined the point prevalence of the use of viagra, testosterone, and antidepressants. We examined bivariate and multivariate associations between the use of each drug and demographics, health status, substance use, psychological symptoms, and sexual risk.

RESULTS

The current use of antidepressants was 21%, testosterone 19%, and viagra 12%. Some viagra users reported using drugs that could interact dangerously with viagra. The use of viagra, testosterone, or antidepressants was related to unprotected receptive anal intercourse and unprotected insertive oral intercourse (UIOI) with both HIV-positive and HIV-negative/unknown-status casual partners. The use of viagra was also associated with unprotected insertive anal intercourse. In multivariate models, viagra use was associated with being older, more educated, using ketamine, and engaging in UIOI with HIV-negative/unknown-status casual partners. Testosterone use was associated with being more educated and using nitrites (poppers). Antidepressant use was associated with race, using poppers, and being more depressed.

CONCLUSION

Prescription medications used by HIV-positive men can have unintended negative effects such as drug interactions or associations with risky sexual behavior, particularly a drug such as viagra that is fast acting, short lasting, and provides a desirable effect. Physicians should discuss these issues with patients when prescribing, and interventions should address these challenges.

Condom use and perceived risk of HIV transmission among sexually active HIV-positive men who have sex with men

This study examined the association between HIV transmission risk perception and the sexual risk behaviors of HIV-positive men who have sex with men. Respondents rated the degree of risk of transmitting HIV through insertive anal intercourse and insertive oral sex. We examined (a) the perceived level of HIV transmission risk assigned to each sexual behavior and (b) the association between perceived risk for HIV transmission and condom use during insertive anal intercourse and insertive oral sex. We found for behaviors that have achieved less risk consensus that as transmission risk perception increases, so too does the likelihood of condom use. This study highlights the need for more research in understanding how perceived health risk to others influences protective behaviors.

Sexual risk of HIV transmission is missed by traditional methods of data collection

Brief acts of unprotected anal sex (i.e.'dipping') have not been systematically measured in AIDS research. Eleven per cent of HIV-positive men who reported that they had not engaged in any unprotected insertive anal intercourse with an HIV-negative or unknown status partner reported that they did engage in insertive 'dipping'. Men reported 'dipping' an average of 5.1 times, representing 773 acts of insertive intercourse that would have been missed by traditional methods of sexual data behavior.

Self-Perceived Responsibility of HIV-Seropositive Men Who Have Sex with Men for Preventing HIV Transmission

Relatively little attention has been paid to unique factors that may motivate HIV-seropositive men who have sex with men (MSM) to prevent HIV transmission. This study examines the beliefs of 250 HIV-seropositive MSM about their responsibility for protecting sex partners from HIV infection. Participants completed an open-ended interview about their sexual practices, substance use, and other HIV-related issues. Seventy percent of participants were men of color. Most participants (72%) spontaneously mentioned issues related to responsibility that were represented by three themes: (1) personal responsibility for protecting sex partners, (2) partners' responsibility for protecting themselves, and (3) mutual responsibility. These beliefs were expressed by 63%, 24%, and 12% of respondents, respectively. Motivations underlying beliefs about personal responsibility included altruism, self-standards, and self-interest. Beliefs about personal responsibility were influenced by participant characteristics, partner characteristics, disclosure of HIV status, and contextual factors. The findings suggest that self-perceived responsibility may be an important factor that affects HIV-seropositive MSM's sexual decision making.

Correlates of sexual risk behaviors among HIV-positive men who have sex with men

This study examines correlates of unprotected sexual risk practices of an ethnically diverse sample of HIV-seropositive men who have sex with men (MSM) from the New York City and San Francisco metropolitan areas. Participants completed a self-report survey that assessed sexual risk behaviors and potential correlates. A total of 367 men reported sex with a casual male partner in the previous 3 months. Participants were divided into three groups based on level of HIV-transmission risk with HIV negative or unknown-status partners: no unprotected anal sex (58.9%), unprotected receptive anal sex only (14.2%), and unprotected insertive anal sex (22.6%). Multivariate logistic regression analyses indicated that men reporting unprotected anal insertive sex perceived less responsibility to protect their partners from HIV. Men reporting no unprotected anal sex also reported less use of nitrate inhalants, lower temptation for unsafe sex, and fewer HIV-negative and unknown-status partners. Men reporting unprotected receptive anal sex were less anxious than the other two groups but also reported greater depression than those not reporting unprotected anal sex and greater loneliness than those reporting unprotected anal insertive sex. Implications for interventions with HIV-positive MSM are presented.

Interests in HIV prevention topics of HIV-seropositive men who have sex with men

As improved medical treatments have extended the lives of persons with HIV, prevention programs increasingly address these persons' ability to adopt and sustain HIV risk reduction behavior. Little is known about which HIV-seropositive persons would most likely use prevention programs or what program topics would best meet the needs of this population. A diverse sample of HIV-seropositive men who have sex with men (MSM, N = 206) rated their interest in a variety of program topics addressing physical and mental health issues. Topics specific to HIV prevention were of interest to most MSM, but the level of interest was generally lower than for other topics. Compared with White MSM, African American MSM had higher overall interest in programs addressing safer sex and programs addressing serostatus disclosure. Higher active coping was related to more interest in a broad range of program topics for HIV-seropositive men, programs addressing safer sex, and programs addressing serostatus disclosure. Risk behavior was not associated with program interests. Gaining a better understanding of interest in a variety of program topics among persons living with HIV is an important step in enhancing HIV transmission prevention programs.
