Prevalence, Comorbidity, and Correlates of Psychiatric and Substance Use Disorders and Associations with HIV Risk Behaviors in a Multisite Cohort of Women Living with HIV

We used the World Health Organization’s Composite International Diagnostic Interview to determine the prevalence, comorbidity, and correlates of lifetime and 12-month behavioral health disorders in a multisite cohort of 1027 women living with HIV in the United States. Most (82.6%) had one or more lifetime disorders including 34.2% with mood disorders, 61.6% with anxiety disorders, and 58.3% with substance use disorders. Over half (53.9%) had at least one 12-month disorder, including 22.1% with mood disorders, 45.4% with anxiety disorders, and 11.1% with substance use disorders. Behavioral health disorder onset preceded HIV diagnosis by an average of 19 years. In multivariable models, likelihood of disorders was associated with women’s race/ethnicity, employment status, and income. Women with 12-month behavioral health disorders were significantly more likely than their counterparts to engage in subsequent sexual and substance use HIV risk behaviors. We discuss the complex physical and behavioral health needs of women living with HIV.

Drug Use and High-Risk Sexual Behaviors of Women at a Drop-In Center in Mazandaran Province, Iran, 2014

BACKGROUND

Female drug users are more likely to transmit human immunodeficiency virus (HIV) to their sexual partners. Little is known about HIV, sexually transmitted diseases (STDs), cervicitis, and drug abuse among female sex workers in Iran.

OBJECTIVES

Therefore, this study was conducted at a drop-in center (DIC) in Iran to investigate the prevalence of HIV associated risk factors, the prevalence of drug use, high-risk sexual behaviors, and the relationship between the associated factors in women.

PATIENTS AND METHODS

This quantitative cross-sectional study was conducted on 190 female sex workers (SW) in a DIC in Sari, Mazandaran, Northern Iran, in January and February 2014. The study sample was selected through census sampling. In the end, 190 female SWs referring to the DIC participated in our study. There was no limitation in sampling. The self-administered questionnaire was completed via an interview.

RESULTS

The results showed that 39% of the female SWs were less than 30 years old and 64% had elementary school education. In addition, 59% of the participants took some type of illegal drugs and 1.1% of them were reportedly injecting drug users. Moreover, 43% of them had substance dependent husbands, and 39% were reportedly regular condom users. They had 1 - 10 sexual partners on average per week. The overall prevalence of HIV infection was 4%. A significant relationship was found between the type of drugs used and factors such as having a substance dependent husband, use of condom during the last sexual contact, regular condom use, and the number of sexual acts per week. A significant correlation exists between using psychiatric drugs and factors like regular condom use, education, cervicitis, and the number of sexual conducts per week.

CONCLUSIONS

Female sex workers often engage in sex for financial reasons and are at high risk of drug abuse, HIV, and cervicitis. In addition, the rate of cervicitis among females with high-risk sexual behavior is considerable in Mazandaran, Iran. Therefore, the state authorities should provide sex workers with health care services and help them acquire a good job to support their life.

Efficacy of a Multi-level Intervention to Reduce Injecting and Sexual Risk Behaviors among HIV-Infected People Who Inject Drugs in Vietnam: A Four-Arm Randomized Controlled Trial

Introduction

Injecting drug use is a primary driver of HIV epidemics in many countries. People who inject drugs (PWID) and are HIV infected are often doubly stigmatized and many encounter difficulties reducing risk behaviors. Prevention interventions for HIV-infected PWID that provide enhanced support at the individual, family, and community level to facilitate risk-reduction are needed.

Methods

455 HIV-infected PWID and 355 of their HIV negative injecting network members living in 32 sub-districts in Thai Nguyen Province were enrolled. We conducted a two-stage randomization: First, sub-districts were randomized to either a community video screening and house-to-house visits or standard of care educational pamphlets. Second, within each sub-district, participants were randomized to receive either enhanced individual level post-test counseling and group support sessions or standard of care HIV testing and counseling. This resulted in four arms: 1) standard of care; 2) community level intervention; 3) individual level intervention; and 4) community plus individual intervention. Follow-up was conducted at 6, 12, 18, and 24 months. Primary outcomes were self-reported HIV injecting and sexual risk behaviors. Secondary outcomes included HIV incidence among HIV negative network members.

Results

Fewer participants reported sharing injecting equipment and unprotected sex from baseline to 24 months in all arms (77% to 4% and 24% to 5% respectively). There were no significant differences at the 24-month visit among the 4 arms (Wald = 3.40 (3 df); p = 0.33; Wald = 6.73 (3 df); p = 0.08). There were a total of 4 HIV seroconversions over 24 months with no significant difference between intervention and control arms.

Discussion

Understanding the mechanisms through which all arms, particularly the control arm, demonstrated both low risk behaviors and low HIV incidence has important implications for policy and prevention programming.

Syndemic vulnerability, sexual and injection risk behaviors, and HIV continuum of care outcomes in HIV-positive injection drug users

Limited investigations have been conducted on syndemics and HIV continuum of care outcomes. Using baseline data from a multi-site, randomized controlled study of HIV-positive injection drug users (n = 1,052), we examined whether psychosocial factors co-occurred, and whether these factors were additively associated with behavioral and HIV continuum of care outcomes. Experiencing one type of psychosocial problem was significantly (p < 0.05) associated with an increased odds of experiencing another type of problem. Persons with 3 or more psychosocial problems were significantly more likely to report sexual and injection risk behaviors and were less likely to be adherent to HIV medications. Persons with 4 or more problems were less likely to be virally suppressed. Reporting any problems was associated with not currently taking HIV medications. Our findings highlight the association of syndemics not only with risk behaviors, but also with outcomes related to the continuum of care for HIV-positive persons.

High-risk behaviors after release from incarceration among people who inject drugs in St. Petersburg, Russia

BACKGROUND

Injection drug use, infectious disease, and incarceration are inextricably linked in Russia. We aimed to identify factors associated with time to relapse (first opioid injection after release from prison) and using a non-sterile, previously used syringe at relapse in a sample of people who inject drugs in St. Petersburg.

METHODS

We collected data on time from release to relapse among individuals with a history of incarceration, a subsample of a larger study among people who inject drugs. Proportional hazards and logistic regression were used to identify factors associated with time to relapse and injection with a non-sterile previously used syringe at relapse, respectively.

RESULTS

The median time to relapse after release was 30 days. Factors that were independently associated with relapsing sooner were being a native of St. Petersburg compared to not being native (AHR: 1.64; 95% CI 1.15-2.33), unemployed at relapse compared to employed (AHR: 4.49; 95% CI 2.96-6.82) and receiving a previous diagnosis of HBV and HCV compared to no previous diagnosis (AHR: 1.49; 95% CI 1.03-2.14). Unemployment at relapse was also significant in modeling injection with a non-sterile, previously used syringe at relapse compared to those who were employed (AOR: 6.80; 95% CI 1.96-23.59).

CONCLUSIONS

Unemployment was an important correlate for both resuming opioid injection after release and using a non-sterile previously used syringe at relapse. Linkage to medical, harm reduction, and employment services should be developed for incarcerated Russian people who inject drugs prior to release.

Secondary prevention of HIV in the United States: past, current, and future perspectives

To provide a synopsis of past, current, and potential next-generation approaches to prevention for positives (PfP) interventions in the United States. For a variety of reasons, PfP interventions, with the goals of limiting HIV transmission from people living with HIV/AIDS (PLWHA) to others and protecting the health of PLWHA, did not appear with any frequency in the United States until about 2000. Even today, the number and breadth of evidence-based PfP interventions is very limited. Nevertheless, meta-analytic evidence demonstrates that such interventions can be effective, perhaps even more so than interventions targeting HIV-uninfected individuals. We review early and more recent PfP interventions and suggest that next-generation PfP interventions must involve behavioral and biologic components and target any element that affects HIV risk behavior and/or infectivity. Next-generation PfP interventions should include increased HIV testing to identify additional PLWHA, components to initiate and maintain HIV care, to initiate antiretroviral therapy and promote adherence, and to reduce sexual and injection drug use risk behavior, as well as ancillary treatments and referrals to services. Comprehensive next-generation PfP interventions, including all of these elements and effective linkages among them, are discussed.

Associations between medical service use and HIV risk among HIV-positive drug users in Baltimore, MD

The objectives of this study were first, to identify psychosocial and medical service utilization factors associated with unprotected sex with HIV-negative or unknown serostatus partners among persons living with HIV/AIDS, and second, to identify risk behaviours associated with HIV medical service use. We assessed 244 HIV-positive participants in an HIV intervention targeting drug users (1997-99). Fifty-seven per cent of HIV-positive participants reported unprotected sex within the past 90 days, 16.4% with serodiscordant partners. Odds of risky sex were lower among those currently receiving HIV medical care (odds ratio (OR)=0.36), and were greater among females (OR=2.6), those having friends with lower norms of condom use (OR=3.3), and those having a main sexual partner (OR=6.2). Lower odds of receiving HIV medical care were associated with current drug use (OR=0.33), sharing drugs with a sex partner (OR=0.27), and exchanging sex for drugs or money (OR=0.24). Findings suggest the importance of community-based HIV prevention intervention targeting HIV-positive drug users not recovery HIV medical care.

Is sexual serosorting occurring among HIV-positive injection drug users? Comparison between those with HIV-positive partners only, HIV-negative partners only, and those with any partners of unknown status

Using baseline data from a multi-site, randomized controlled study (INSPIRE), we categorized 999 HIV-positive IDUs into three groups based on serostatus of their sex partners. Our data provide some evidence for serosorting occurring in our sample; about 40% of the sample had sex exclusively with HIV-positive partners, and about half of them reported having unprotected sex with these partners. Twenty per cent had sex exclusively with HIV-negative partners; their sexual behaviors tended to be least risky with about two-thirds reporting their sex was protected. However, we also found that another 40% had at least one partner of unknown HIV status and sexual and drug risk was the highest among them. They were also least empowered, showing attributes that may undermine HIV prevention. Some of these findings are consistent with findings from MSM studies, suggesting that partner selection practices are similar between primarily heterosexual IDUs and MSM.

HIV risk behaviours and determinants among people living with HIV/AIDS in Vietnam

There is a potentially high risk of HIV spreading from people living with HIV/AIDS. We conducted a cross-sectional study to examine HIV risk behaviours and their determinants among people living with HIV/AIDS. Eighty-two percent had been sexually active. Sex with multiple partners was reported by 20% and consistent condom use by about one third. More than half of the participants (52%) reported having injected drugs during the previous month, and 35% of those had shared needles and syringes. Voluntary HIV testing and having received condoms or injection equipment from the local HIV prevention program, were found to be significantly associated with fewer HIV risk behaviours. Having learned recently about personal HIV status, multiple sex partners, low educational attainment and young age were found to be associated with higher HIV risk behaviours. Giving high priority to targeted preventive and support programmes is likely to be a highly cost-effective strategy.

Secondary prevention of HIV infection: the current state of prevention for positives

PURPOSE OF REVIEW

To provide a state-of-the-science review of the literature on secondary prevention of HIV infection or 'prevention for positives' (PfP) interventions.

RECENT FINDINGS

Early work on PfP focused on understanding the dynamics of risky behavior among People Living with HIV/AIDS (PLWH) and on designing, implementing, and evaluating a limited number of interventions to promote safer sexual and drug use behavior in this population (i.e., PfP interventions). Previous meta-analyses demonstrated that PfP interventions can effectively promote safer behavior. However, the understanding of risk dynamics among PLWH and the extant number and breadth of effective PfP interventions were scant. Recent work has addressed some of these problems, yielding greater understanding of risk dynamics and providing additional, effective interventions. Still, only a modest number of recent, rigorously evaluated, effective interventions have been identified. New ideas for creating stronger, more integrated, and effective PfP interventions have emerged that will guide future intervention research and practice.

SUMMARY

There remains much to be done to understand why, when, and under what conditions PLWH practice risk. Substantial work also needs to be performed to design, implement, rigorously evaluate, and when effective, to disseminate widely, additional, evidence-based PfP interventions targeting diverse populations. Directing such interventions to populations of PLWH at greatest risk for transmission of HIV has the potential to yield significant impact on the pandemic.

The context of HIV risk behaviours among HIV-positive injection drug users in Viet Nam: moving toward effective harm reduction

Background

Injection drug users represent the largest proportion of all HIV reported cases in Viet Nam. This study aimed to explore the perceptions of risk and risk behaviours among HIV-positive injection drug users, and their experiences related to safe injection and safe sex practices.

Methods

This study used multiple qualitative methods in data collection including in-depth interviews, focus group discussions and participant observation with HIV-positive injection drug users.

Results

The informants described a change in the sharing practices among injection drug users towards more precautions and what was considered 'low risk sharing', like sharing among seroconcordant partners and borrowing rather than lending. However risky practices like re-use of injection equipment and 'syringe pulling' i.e. the use of left-over drugs in particular, were frequently described and observed. Needle and syringe distribution programmes were in place but carrying needles and syringes and particularly drugs could result in being arrested and fined. Fear of rejection and of loss of intimacy made disclosure difficult and was perceived as a major obstacle for condom use among recently diagnosed HIV infected individuals.

Conclusion

HIV-positive injection drug users continue to practice HIV risk behaviours. The anti-drug law and the police crack-down policy appeared as critical factors hampering ongoing prevention efforts with needle and syringe distribution programmes in Viet Nam. Drastic policy measures are needed to reduce the very high HIV prevalence among injection drug users.

Sexual behavior and risks for HIV infection and transmission among male injecting drug users in Yunnan, China

OBJECTIVES

To analyze the risk factors, particularly sexual behaviors, associated with HIV infection, and to describe the risks for HIV transmission among male injecting drug users (IDUs) in China.

METHODS

A cross-sectional study of 314 IDUs in Yunnan Province was conducted. Information on demographics, HIV serostatus, and sexual and drug-using behaviors was collected.

RESULTS

HIV prevalence among the study subjects was 59.9%. HIV infection was associated with older age (> or = 27 years), early drug initiation (at < or = 20 years of age), and frequent injection (> or = once a day). Thirty-seven percent reported multiple sexual partners. Consistent condom use rates were lowest with regular partners (23.8%), followed by 42.5% with casual partners, and 57.3% with female sex workers. Ninety-eight percent of subjects received high 'HIV knowledge' scores. Few of the subjects who needed medical care sought it out.

CONCLUSIONS

Despite awareness of HIV, needle sharing and unprotected sex persist in the population, and the HIV prevalence is high. Further interventions should not only seek to educate but also to reduce high-risk behaviors.

Hepatitis Vaccination and Infection Among Gay, Bisexual, and Other Men Who Have Sex with Men who Attend Gyms in New York City

The authors examined hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccination rates, hepatitis infection, and health care access in a gym-attending sample of 311 gay, bisexual, and other men who have sex with men (MSM) in New York City. Overall, 69% reported having been vaccinated for HAV and 70% reported having been vaccinated for HBV. Multivariate models were used to identify predictors of HAV and HBV vaccination, and younger men, HIV-positive men, and men who had access to a doctor or clinic were more likely to be vaccinated than older men, HIVnegative men, and men without access to a doctor or clinic. Men with health insurance coverage were more likely to have received HBV vaccination than men without coverage. Findings indicate that there is still a significant proportion of unvaccinated men in our sample.

Results from a randomized controlled trial of a peer-mentoring intervention to reduce HIV transmission and increase access to care and adherence to HIV medications among HIV-seropositive injection drug users

BACKGROUND

There is a lack of effective behavioral interventions for HIV-positive injection drug users (IDUs). We sought to evaluate the efficacy of an intervention to reduce sexual and injection transmission risk behaviors and to increase utilization of medical care and adherence to HIV medications among this population.

METHODS

HIV-positive IDUs (n=966) recruited in 4 US cities were randomly assigned to a 10-session peer mentoring intervention or to an 8-session video discussion intervention (control condition). Participants completed audio computer-assisted self-interviews and had their blood drawn to measure CD4 cell count and viral load at baseline and at 3-month (no blood), 6-month, and 12-month follow-ups.

RESULTS

Overall retention rates for randomized participants were 87%, 83%, and 85% at 3, 6, and 12 months, respectively. Participants in both conditions reported significant reductions from baseline in injection and sexual transmission risk behaviors, but there were no significant differences between conditions. Participants in both conditions reported no change in medical care and adherence, and there were no significant differences between conditions.

CONCLUSIONS

Both interventions led to decreases in risk behaviors but no changes in medical outcomes. The characteristics of the trial that may have contributed to these results are examined, and directions for future research are identified.

Beliefs that condoms reduce sexual pleasure-gender differences in correlates among heterosexual HIV-positive injection drug users (IDUs)

Studies consistently find that negative condom beliefs or attitudes are significantly associated with less condom use in various populations, including HIV-positive injection drug users (IDUs). As part of efforts to reduce sexual risk among HIV-positive IDUs, one of the goals of HIV interventions should be the promotion of positive condom beliefs. In this paper we sought to identify the correlates of negative condom beliefs and examined whether such correlates varied by gender, using a subsample (those with an opposite-sex main partner; n = 348) of baseline data collected as part of a randomized controlled study of HIV-positive IDUs. In multivariate analyses, we found more significant correlates for women than for men. With men, perception that their sex partner is not supportive of condom use (negative partner norm) was the only significant correlate (Beta = -0.30; p < 0.01; R (2) = 0.18). Among women, negative partner norm (Beta = -0.18; p < 0.05); having less knowledge about HIV, STD, and hepatitis (Beta = -0.16; p < 0.05); lower self-efficacy for using a condom (Beta = -0.40; p < 0.01); and more episodes of partner violence (Beta = 0.15; p < 0.05) were significantly associated with negative condom beliefs (R (2) = 0.36). These findings suggest important gender-specific factors to consider in interventions that seek to promote positive condom beliefs among HIV-positive IDUs.

High-risk behaviors in women who use crack: knowledge of HIV serostatus and risk behavior

PURPOSE

To determine whether crack cocaine-using women who are aware of their HIV serostatus have made modifications in risk behaviors, we compared known HIV-positive (HIV+) and HIV-negative (HIV-) users with respect to sexual risk behaviors, prevalence of sexually transmitted infections (STIs) and vaginitis, and correlates of unprotected sex.

METHODS

We used a cross-sectional design with street outreach, recruitment, and interviews of sexually active crack cocaine using women. Women received testing for HIV, STIs, and vaginitis.

RESULTS

Sixty-one HIV+ and 117 HIV- women were enrolled. HIV+ women were significantly more likely to be African-American. There were no significant differences in drug use, types of sexual partners, number of paying partners, attitudes regarding condoms, or STI diagnoses. HIV+ women were less likely to engage in unprotected sex compared with HIV- women (56% vs. 75%, adjusted odds ratio [AOR], 0.36; 95% confidence interval [CI], 0.13-0.99). Among HIV+ women, unprotected sex was negatively associated with stronger beliefs regarding the protective value of condoms (AOR, 0.07; 95% CI, 0.01-0.67) and concurrent injection-drug use (AOR, 0.19; 95% CI, 0.04-0.99).

CONCLUSIONS

Although the majority of crack using HIV+ crack using women in this sample continued to engage in high-risk sexual activities, they were less likely to do so than HIV- women. Interventions targeting this population are needed.

Providers' HIV prevention discussions with HIV-seropositive injection drug users

Public health agencies have recommended incorporating HIV prevention counseling into the medical care of persons living with HIV/AIDS. Injection drug users (IDUs) especially need HIV risk-reduction counseling because of their high risk for HIV transmission through both sexual and injection behaviors. The objective of this study was to assess the prevalence of, and patient factors associated with, the delivery of HIV prevention messages to HIV-seropositive IDUs in primary care settings. A majority of participants reported having an HIV prevention discussion with their provider during their most recent primary care visit. Factors significantly associated with report of such discussion were being Hispanic or non-Hispanic Black; high school education or less; and better perception of engagement with provider. Medical providers should provide prevention messages to all HIV-seropositive IDUs, regardless of demographic factors. Effective HIV prevention interventions in primary care settings, including interventions to improve patient-provider communication, are needed for HIV-seropositive IDUs.

Unprotected sexual behavior among heterosexual HIV-positive injection drug using men: associations by partner type and partner serostatus

Few studies have examined sexual risk behaviors of HIV-positive, heterosexual, injection drug using (IDU) men. We investigated such behaviors and associations with risk among sexually active, HIV-positive IDU men who reported only female sex partners in the 3 months prior to baseline interview. We examined associations separately for four non-exclusive groups of men by crossing partner type (main or casual) and partner serostatus (HIV-positive or HIV-negative/unknown). Of 732 male participants, 469 (64%) were sexually active with only female partners. Of these 469 men, 155 (33%) reported sex with HIV-positive main partners, 127 (27%) with HIV-negative or unknown serostatus main partners, 145 (31%) with HIV-positive casual partners, and 192 (41%) with HIV-negative/unknown serostatus casual partners. Significant multivariate associations for unprotected sex with HIV-negative or unknown serostatus main partners were less self-efficacy to use condoms, weaker partner norms supporting condoms, and more negative condom beliefs. Similar correlates were found for unprotected sex with HIV-positive main and casual partners. In addition, alcohol or drug use during sex was a significant correlate of unprotected sex with HIV-positive main partners, while depression was significant for HIV-positive casual partners. For unprotected sex with HIV-negative/unknown status casual partners, self-efficacy for condom use, sex trade, and education were significant multivariate correlates. A combination of broad and tailored intervention strategies based on the relationship pattern of men's lives may provide the most benefit for reducing unprotected sex with female partners.

Behavioral interventions for HIV-positive and HCV-positive drug users

The nature, context and frequency of use of various licit and illicit non-injection drugs associated with an elevated risk of HIV infection. Beyond HIV, a high proportion of HIV-infected IDUs are co-infected with HCV (hepatitis C virus). In this review, we provide a brief review of the epidemiology of these problems, discuss behavioral interventions that can reduce ongoing high risk behaviors among HIV-seropositive IDUs and MSM-DUs, and review the literature which has evaluated their effectiveness. The majority of these interventions have focused on HIV-seronegative heterosexuals and therefore need to be considered in this larger context; however, where possible we discuss the potential impact of these interventions among HIV-seropositive persons. In addition, we briefly discuss interventions which have the potential to simultaneously reduce ongoing transmission of both HIV and HCV. Finally, given the dearth of information on the effectiveness of behavioral interventions in reducing the burden of the HIV and HCV epidemics among persons already infected with either or both viruses, we describe some newer, promising interventions and offer suggestions for future studies.

Association of violence victimization with inconsistent condom use in HIV-infected persons

The association of violence victimization with current condom use in HIV-infected persons was examined in this cross-sectional study. The HIV-Alcohol Longitudinal Cohort (HIV-ALC) recruited HIV-infected participants with a history of alcohol problems. Interviews assessed violence histories and current sexual behaviors. Of the 349 participants (79% men), 38% reported inconsistent condom use and 80% reported a violence history. Lifetime sexual violence was reported by 40% and lifetime physical violence (without sexual violence) by 40%. Participants reporting lifetime sexual violence had greater odds of inconsistent condom use than participants without any history of violence. A history of childhood sexual violence was also associated with greater odds of inconsistent condom use than participants without a history of childhood sexual violence. A history of sexual violence may in part explain HIV-infected persons' greater risk for transmitting HIV through high-risk sexual behaviors.

HIV Drug Resistance and HIV Transmission Risk Behaviors Among Active Injection Drug Users

HIV(+) injection drug users in clinical care may harbor and transmit drug-resistant HIV. We performed a retrospective study of HIV drug resistance and risk behavior among HIV(+) injection drug users in care to determine the number of needle-sharing events that involved and the proportion of sharing partners exposed to drug-resistant HIV. Among 180 HIV injection drug users, 55 (31%) reported injecting drugs in the previous month, and 22 of these (40%) shared needles and/or works 148 times with 296 partners, of whom 271 (92%) were thought to be HIV(-) or status unknown. Further, 55 (31%) drug users harbored resistant HIV, including 5 (3% of total) who also shared needles and/or works a total of 27 times with 44 partners (18% of all sharing events and 15% of all exposed partners). A small proportion of injection drug users receiving clinical care engage in injection risk behavior and carry resistant HIV; however, because of multiple partners and needle-sharing events, they expose a substantial number of individuals to drug-resistant HIV. Strategies to reduce injection drug use risk behaviors among patients in clinical care are needed to reduce the transmission of sensitive and resistant HIV.

Trends of HIV risk behaviors in a cohort of injecting drug users and their sex partners in Miami, Florida, 1988-1998

A cohort of 111 injection drug users (IDUs) and their sex partners was assessed in 1988 concerning risk behaviors for HIV and knowledge of HIV/AIDS. Ten years later, in 1998, the cohort was reassessed using the same instrument. All who were HIV negative in 1988 were retested by blood draw for antibodies to HIV. A paired analysis was utilized to determine individual changes in risk behaviors for three serostatus groups--those who remained HIV negative (long-term HIV negatives), seroconverters, and those positive in 1988 (long-term HIV positives). Incidence was twice as high for sex partners (37.5%) as for IDUs (18.0%). Drug and needle use risk behaviors, except crack use, showed decreases; sexual risk behaviors were less amenable to change. Knowledge significantly increased among the long-term HIV negatives and seroconverters but not among those HIV positive in 1988. This analysis demonstrates the need for continued intervention among IDUs and their sex partners.

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.

Interventions for Seropositive Injectors—Research and Evaluation

BACKGROUND

Behavioral interventions to address the complex medical and HIV risk reduction needs of HIV-seropositive (HIV-positive) injection drug users (IDUs) are urgently needed. We describe the development of Interventions for Seropositive Injectors-Research and Evaluation (INSPIRE), a randomized controlled trial of an integrated intervention for HIV-positive IDUs, and the characteristics of the baseline sample.

METHODS

HIV-positive IDUs were recruited from community settings in 4 US cities. After completing a baseline assessment, participants who attended the first session were randomly assigned to (1) a 10-session peer mentoring intervention designed to improve utilization of HIV care, to improve adherence to HIV medications, and to reduce sexual and injection risk or (2) an 8-session videotape control. Periodic follow-up for 12 months is ongoing.

RESULTS

A total of 1161 HIV-positive IDUs completed the baseline assessment, and 966 (83%) were randomized. Retention rates are greater than 80% for all follow-up periods. Approximately 79% of baseline participants reported a recent medical visit, 49% were taking highly active antiretroviral therapy, and 19% had an undetectable viral load. Use of injection and noninjection substances was prevalent, and sexual and injection risks were each reported by more than 25% of participants.

CONCLUSION

There is a need for an integrated intervention for HIV-positive IDUs, and these data show the acceptability of such an approach.

Injection drug use and crack cocaine smoking: independent and dual risk behaviors for HIV infection

PURPOSE

Previous studies have examined the practices of injecting drugs or smoking crack cocaine as high-risk, but independent, factors for HIV transmission. To explore the independent and dual risks of injection practices and crack smoking, this study examined HIV seroprevalence rates among distinct drug user groups, based on patterns of daily administration.

METHODS

A sample of 3,555 drug users and neighborhood controls in urban Miami, FL and rural Belle Glade and Immokalee, FL were partitioned into four mutually-exclusive groups: 1) injection drug users (IDUs); 2) crack-cocaine smokers; 3) dual users who both smoked crack and injected drugs; and 4) non-drug-user controls.

RESULTS

HIV seroprevalence rates were 45.1% for IDUs, 30.5% for dual users, 20.1% for crack smokers and 7.3% for controls. Multivariate logistic regression analysis found that when compared with controls odds ratios for HIV seropositivity were 9.81 for IDUs, 5.27 for dual users, and 2.24 for crack smokers.

CONCLUSIONS

These findings provide evidence of: 1) behavioral and structural co-factors that influence HIV exposure patterns among drug users; and 2) the substantially higher risk of HIV infection among IDUs compared with other drug users. Intervention strategies must be tailored for the specific drug use subpopulations to optimize efficacy.

"The rock always comes first": drug users' accounts about using formal health care

Illicit drug use remains a significant public health threat. The issues surrounding drug use are recognized by public health professionals as important for several reasons. The incidence and prevalence of drug use persists in spite of the extensive societal, interpersonal, and individual consequences. In addition, the chronic health issues and health care costs associated with drug use continue to spiral. A wide variety of quantitative studies have examined the extent of health care problems, access, cost, and health care satisfaction among illicit drug users. While these studies offer important information through survey formats, fewer studies focus on subjective constructions of health care management from the users' perspective. This article examines the elements of the decision-making process involved in accessing formal health care among chronic and injecting street drug users. Twenty-eight in-depth interviews provide the data for this analysis, which is part of a large quantitative study of 1,479 injecting and chronic drug users and nondrug users in Miami, Florida. By exploring the elements of health care access through the eyes of the drug users, researchers and treatment professionals may gain insights into new ways to improve health care access for this at-risk population.

Use of a public sexually transmitted disease clinic by known HIV-positive adults: decreased self-reported risk behavior and increased disease incidence

High-risk sexual behavior by HIV-positive individuals is an important factor contributing to the spread of the HIV epidemic. We conducted a retrospective chart review to compare self-reported sexually transmitted disease (STD) risk behavior and clinic diagnoses of known HIV-positive clients attending Miami-Dade County STD clinics with those of uninfected controls. One hundred ninety-one HIV-positive clients and 191 HIV-negative controls, 130 (68.1%) men and 61 (31.9%) women, were included in the analysis. HIV-positive clients were more likely than controls to report no sexual activity in the last 2 months (odds ratio [OR] = 2.6, 95% confidence interval [CI]: 1.5-4.5) or, if active, to report condom use at last sexual intercourse (OR = 3.1, CI: 1.9-5.3). However, HIV-positive clients were more likely to be diagnosed with infectious syphilis (OR = 13.0, CI: 1.6-99.4) and/or gonorrhea (OR = 2.1, CI: 1.1-4.2) than controls. This may be a result of overreporting of condom use or sexual activity in high-risk sexual networks with inefficient use of condoms. Ongoing sexual risk behavior and access to HIV primary care are important issues in this population.
