Randomised, controlled, community-level HIV-prevention intervention for sexual-risk behaviour among homosexual men in US cities

BACKGROUND Community-level interventions may be helpful in population-focused HIV prevention. If members of populations at risk of HIV infection who are popular with other members can be engaged to advocate the benefits of behaviour change to peers, decreases in risk behaviour may be possible. We assessed a community-level intervention to lower the risk of HIV infection, focusing on men patronising gay bars in eight small US cities. METHODS We used a randomised community-level field design. Four cities received the intervention and four control cities did not. Participants were men from each city who went to gay bars. Men completed surveys about their sexual behaviour on entering the bars during 3-night periods at baseline and at 1-year follow-up. In the control cities, HIV educational materials were placed in the bars. In the intervention cities, we recruited popular homosexual men in the community and trained them to spread behaviour-change endorsements and recommendations to their peers through conversation. FINDINGS Population-level of risk behaviour decreased significantly in the intervention cities compared with the control cities at 1-year follow-up, after exclusion of surveys completed by transients and men with exclusive sexual partners in a city-level analysis, in the intervention cities we found a reduction in the mean frequency of unprotected anal intercourse during the previous 2 months (baseline 1.68 occasions; follow-up 0.59: p = 0.04) and an increase in the mean percentage of occasions of anal intercourse protected by condoms (baseline 44.7%; follow-up 66.8%, p = 0.02). Increased numbers of condoms taken from dispensers in intervention-city bars corroborated risk-behaviour self-reports. INTERPRETATION Popular and well-liked members of a community who systematically endorse and recommend risk-reduction behaviour can influence the sexual-risk practices of others in their social networks. Natural styles of communication, such as conversations, brought about population-level changes in risk behaviour.

Internalized stigma among people living with HIV-AIDS.

HIV is recognized as a highly stigmatized disease; however, there has been a lack of research on the internalization of this stigma by seropositive people. This study examined internalized stigma among HIV-positive men and women (N = 268) in Milwaukee and Madison, Wisconsin, and New York City. The majority of the sample experienced internalized stigma related to their HIV status. Individuals who experienced high internalized HIV stigma (IHS) had been diagnosed with HIV more recently, their families were less accepting of their illness, they were less likely to ever have attended an HIV support group, and they knew fewer people with HIV. Individuals with high IHS also worried more about spreading their infection to others. Heterosexuals and participants from Wisconsin experienced higher levels of IHS. Hierarchical regression analyses showed that IHS contributed significantly to levels of depression, anxiety, and hopelessness after controlling for the effects of key behavioral and psychosocial variables.

Outcomes of a randomized community-level HIV prevention intervention for women living in 18 low-income housing developments

OBJECTIVES Women in impoverished inner-city neighborhoods are at high risk for contracting HIV. A randomized, multisite community-level HIV prevention trial was undertaken with women living in 18 low-income housing developments in 5 US cities. METHODS Baseline and 12-month follow-up population risk characteristics were assessed by surveying 690 women at both time points. In the 9 intervention condition housing developments, a community-level intervention was undertaken that included HIV risk reduction workshops and community HIV prevention events implemented by women who were popular opinion leaders among their peers. RESULTS The proportion of women in the intervention developments who had any unprotected intercourse in the past 2 months declined from 50% to 37.6%, and the percentage of womens acts of intercourse protected by condoms increased from 30.2% to 47.2%. Among women exposed to intervention activities, the mean frequency of unprotected acts of intercourse in the past 2 months tended to be lower at follow-up (mean = 4.0) than at baseline (mean = 6.0). These changes were corroborated by changes in other risk indicators. CONCLUSIONS Community-level interventions that involve and engage women in neighborhood-based HIV prevention activities can bring about reductions in high-risk sexual behaviors.

Outcomes from a group intervention for coping with HIV/AIDS and childhood sexual abuse: reductions in traumatic stress.

Childhood sexual abuse is common among HIV-infected persons, though few empirically supported treatments addressing sexual abuse are available for men and women with HIV/AIDS. This study reports the outcome from a randomized controlled trial of a group intervention for coping with HIV and sexual abuse. A diverse sample of 202 HIV-positive men and women who were sexually abused as children was randomly assigned to one of three conditions: a 15-session HIV and trauma coping group intervention, a 15-session support group comparison condition, or a waitlist control (later randomly assigned to an intervention condition). Traumatic stress symptoms were assessed at baseline and post-intervention, with analysis conducted for the three-condition comparison followed by analysis of the two-condition comparison between the coping and support group interventions. Participants in the coping group intervention exhibited reductions in intrusive traumatic stress symptoms compared to the waitlist condition and in avoidant traumatic stress symptoms compared to the support group condition. No differences were found between the support group intervention and waitlist conditions. Tests of clinical significance documented the meaningfulness of change in symptoms.

Implications of HIV Treatment Advances for Behavioral Research on AIDS: Protease Inhibitors and New Challenges in HIV Secondary Prevention

Protease inhibitor combination therapies can reduce HTV viral load, improve immune system functioning, and decrease mortality from AIDS. These medical developments raise a host of critical new issues for behavioral research on HTV/AIDS. This article reviews developments in HIV combination therapy regimens and behavioral factors involved in these regimens and focuses on four key behavioral research areas: (a) the development of interventions to promote treatment adherence, (b) psychological coping with HIV/AIDS in the context of new treatments for the disease, (c) the possible influence of treatment on continued risk behavior, and (d) behavioral research in HIV prevention and care policy areas. Advances in HTV medical care have created important new opportunities for health psychologists to contribute to the well-being of persons with HIV/AIDS.

In Their Own Voices A Qualitative Study of Women's Risk for Intimate Partner Violence and HIV in South Africa

This study qualitatively examines the intersections of risk for intimate partner violence (IPV) and HIV infection in South Africa. Eighteen women seeking services for relationship violence were asked semistructured questions regarding their abusive experiences and HIV risk. Participants had experienced myriad forms of abuse, which reinforced each other to create a climate that sustained abuse and multiplied HIV risk. Male partners having multiple concurrent sexual relationships, and poor relationship communication compounded female vulnerability to HIV and abuse. A social environment of silence, male power, and economic constraints enabled abuse to continue. “Breaking the silence” and womens empowerment were suggested solutions.

Effects of a coping intervention on transmission risk behavior among people living with HIV/AIDS and a history of childhood sexual abuse

Objectives:To examine the effect of a 15-session coping group intervention compared with a 15-session therapeutic support group intervention among HIV-positive men and women with a history of childhood sexual abuse (CSA) on sexual transmission risk behavior. Design:A randomized controlled behavioral intervention trial with 12-month follow-up. Methods:A diverse sample of 247 HIV-positive men and women with histories of CSA was randomized to 1 of 2 time-matched group intervention conditions. Sexual behavior was assessed at baseline; immediately after the intervention; and at 4-, 8-, and 12-month follow-up periods (5 assessments). Changes in frequency of unprotected anal and vaginal intercourse by intervention condition were examined using generalized linear mixed models for all partners, and specifically for HIV-negative or serostatus unknown partners. Results:Participants in the HIV and trauma coping intervention condition decreased their frequency of unprotected sexual intercourse more than participants in the support intervention condition for all partners (P < 0.001; d = 0.38, 0.32, and 0.38 at the 4-, 8-, and 12-month follow-up periods, respectively) and for HIV-negative and serostatus unknown partners (P < 0.001; d = 0.48, 0.39, and 0.04 at the 4-, 8-, and 12-month follow-up periods, respectively). Conclusion:A group intervention to address coping with HIV and CSA can be effective in reducing transmission risk behavior among HIV-positive men and women with histories of sexual trauma.

Factors Affecting Disclosure in South African HIV-Positive Pregnant Women

To provide understanding of social and psychological factors that affect disclosure of HIV status among women diagnosed HIV-positive in pregnancy, 438 HIV positive women attending antenatal al clinics in Pretoria, South Africa were invited to participate in a longitudinal study. A total of 293 (62%) women were enrolled from June 2003 to December 2004. Questionnaires assessing sociodemographics and psychological measures were administered during pregnancy and at 3 months postdelivery. At enrollment, 59% had disclosed to their partners and 42% to others. This rose to 67% and 59%, respectively, by follow-up. Logistic regression analysis identified being married (adjusted odds Ratio [AOR] 2.32; 95% confidence interval [CI] 1.20-4.47), prior discussion about testing (AOR 4.19; CI 2.34-7.49), having a partner with tertiary education (AOR 2.76; CI 1.29-5.88) and less experience of violence (AOR 0.48; CI 0.24-0.97) as factors associated with having disclosed to partners prior to enrollment. Better housing (AOR 1.26; CI 1.06-1.49), less financial dependence on partners (AOR 0.46; CI 0.25-0.85), and knowing someone with HIV (AOR 2.13; CI 1.20-3.76) were associated with prior disclosure to others. Increased levels of stigma at baseline decreased the likelihood of disclosure to partners postenrollment (AOR 0.91; CI 0.84-0.98) and increased levels of avoidant coping decreased subsequent disclosure to others (AOR 0.84; CI 0.72-0.97). These results provide understanding of disclosure for women diagnosed as HIV positive in pregnancy, and identify variables that could be used to screen for women who require help.

Emotional Adjustment in Survivors of Sexual Assault Living with HIV-AIDS

This study examined history of sexual assault in 357 men and women living with HIV-AIDS. Participants completed measures of demographic characteristics, sexual assault history, emotional distress and psychiatric symptoms, substance use, and sexual behaviors. Results showed that 68% of women and 35% of men living with HIV-AIDS reported a history of sexual assault since age 15. History of sexual assault was related to history of substance use and mental health treatment. Sexual assault survivors reported greater anxiety, depression, and symptoms of borderline personality and were significantly more likely to report recent unprotected intercourse than persons who had not been sexually assaulted. Results suggest tailoring secondary prevention interventions to meet the needs of HIV-positive survivors of sexual assault.

Mental Health Treatment to Reduce HIV Transmission Risk Behavior: A Positive Prevention Model

Secondary HIV prevention, or “positive prevention,” is concerned with reducing HIV transmission risk behavior and optimizing the health and quality of life of people living with HIV/AIDS (PLWHA). The association between mental health and HIV transmission risk (i.e., sexual risk and poor medication adherence) is well established, although most of this evidence is observational. Further, a number of efficacious mental health treatments are available for PLWHA yet few positive prevention interventions integrate mental health treatment. We propose that mental health treatment, including behavioral and pharmacologic interventions, can lead to reductions in HIV transmission risk behavior and should be a core component of secondary HIV prevention. We present a conceptual model and recommendations to guide future research on the effect of mental health treatment on HIV transmission risk behavior among PLWHA.
