Effectiveness of counseling in the health promotion of HIV-positive clients in the community

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.

Using patient risk indicators to plan prevention strategies in the clinical care setting

OBJECTIVE

Successful behavioral interventions to promote safe sex must be tailored to the sexual behaviors and relationships of individual patients. The aim of this study is to examine the distribution of unprotected anal and vaginal sex (UAV) and nondisclosure (ND) among categories of HIV-positive men and women based on relationship factors. These factors can be easily assessed and used as a basis for tailoring safer sex counseling in the clinic setting.

METHODS

Eight hundred forty HIV-positive persons who were sexually active and attending 1 of 6 clinics in California were surveyed. Participants were categorized on the basis of numbers of partners, sexual orientation, type of relationship, and partner serostatus. Self-reported UAV, ND, and duration of the relationship were reported for each category and were examined.

RESULTS

UAV was lower for those with 1 partner (26%) as compared with those with 2 or more partners (50%). ND was also lower for those with 1 partner (20%) as compared with those with 2 or more partners (60%). For those with 1 main partner, we found no significant differences in UAV by sexual orientation. UAV with seronegative main partners ranged from 16% to 20%, whereas UAV with seropositive partners ranged from 37% to 46%. Among men who have sex with men with 2 or more partners, relationships were more likely to be casual, of short duration, and to have higher levels of UAV and ND.

CONCLUSION

The number of sex partners, type of relationship, and perceived HIV serostatus of a partner influence sexual behaviors and may be an efficient and effective basis for tailoring prevention messages.

A randomized controlled trial to reduce HIV transmission risk behaviors and sexually transmitted diseases among women living with HIV: The WiLLOW Program

OBJECTIVE

To evaluate the efficacy of an intervention to reduce HIV transmission risk behaviors and sexually transmitted diseases (STDs) and enhance HIV-preventive psychosocial and structural factors among women living with HIV.

DESIGN

A randomized controlled trial of 366 women living with HIV in Alabama and Georgia.

INTERVENTION

The intervention emphasized gender pride, maintaining current and identifying new network members, HIV transmission knowledge, communication and condom use skills, and healthy relationships.

PRIMARY OUTCOME

Unprotected vaginal intercourse. OTHER OUTCOMES: Proportion never used condoms, incident STDs, psychosocial factors, and number of supportive network members.

RESULTS

Over the 12-month follow-up, women in the WiLLOW intervention, relative to the comparison, reported fewer episodes of unprotected vaginal intercourse (1.8 vs. 2.5; P = 0.022); were less likely to report never using condoms (odds ratio [OR] = 0.27; P = 0.008); had a lower incidence of bacterial infections (Chlamydia and gonorrhea) (OR = 0.19; P = 0.006); reported greater HIV knowledge and condom use self-efficacy, more network members, fewer beliefs that condoms interfere with sex, and fewer partner-related barriers to condom use; and demonstrated greater skill in using condoms.

CONCLUSION

This is the first trial to demonstrate reductions in risky sexual behavior and incident bacterial STDs and to enhance HIV-preventive psychosocial and structural factors among women living with HIV.

Reducing the sexual risk behaviors of HIV+ individuals: outcome of a randomized controlled trial

Testing behavioral interventions to increase safer sex practices of HIV+ individuals has the potential to significantly reduce the number of new infections. This study evaluated a behavioral intervention designed to reduce the sexual risk behaviors of HIV+individuals. HIV+individuals (N = 387) who reported engaging in unprotected sex with HIV- or partners of unknown serostatus were randomly assigned to (a) a single counseling session targeting problem areas identified by the participant in 3 possible intervention domains (i.e., condom use, negotiation, disclosure); (b) a single-session comprehensive intervention that covered all 3 intervention domains; (c) the same comprehensive intervention, plus 2 monthly booster sessions; or (d) a 3-session diet and exercise attention-control condition. The median number of unprotected sex acts decreased from 14 at baseline to 6, 6, and 4 at 4-, 8-, and 12-month follow-ups, respectively. A repeated measures analysis of variance revealed a significant decrease in unprotected sex acts across all groups across time. A significant Group x Time interaction revealed that the comprehensive-with-boosters group had the most unprotected sex at 8-month follow-up as compared to the other 3 groups. These findings suggest that a brief intervention can result in large reductions in HIV transmission risks among HIV+individuals, but the relative benefit of one intervention approach over another remains unclear.

Sexual risk reduction among HIV-positive drug-using men who have sex with men

According to the US Centers for Disease Control, the majority of new HIV infections are the direct result of unprotected sexual relations between serodiscordant individuals. Thus, the development of behavioral interventions to increase the safer sex practices of HIV-positive individuals has the potential to reduce the number of new infections. Currently, less than 1% of the total US population is infected with HIV. Targeting behavioral interventions to this smaller group of HIV-positive individuals has the potential for making cost-effective reductions in the number of new infections. Despite reports that some HIV-positive individuals continue to engage in high-risk behaviors, interventions designed to prevent secondary transmission of HIV are rare. In this era of highly active antiretroviral therapy (HAART), interventions for HIV-positive individuals are more critical than ever to address the unique challenges and issues they face regarding disclosure and partner notification, use of HAART and sexual risk behavior, and HIV-related stigma. Although a growing number of reports document the efficacy of sexual risk reduction interventions for HIV-positive individuals, to date none of these studies have focused on drug-using populations. This article focuses on sexual risk reduction interventions for HIV-positive men who have sex with men (MSM), the largest group of HIV-positive individuals in the United States. It reviews factors associated with high-risk behaviors and discusses some findings from research with HIV-positive methamphetamine users, including (1) data from a small qualitative study and its implications for the development of new interventions, and (2) baseline data from an ongoing large-scale study of the efficacy of a theory-based sexual risk reduction intervention for HIV-positive methamphetamine-using MSM. The article concludes with a discussion of future research issues, including, for example: Can sexual risks be reduced in the context of active drug use? Are different patterns of drug use, or specific drugs, associated with increased risk behavior? How do gender, race, and culture relate to the efficacy of specific interventions?

High-risk sexual behaviors in a context of substance abuse: a focus group approach

Clinical studies show that heavy and dependant substance users engage with high frequency in high-risk sexual behaviors. To better understand the dynamics of unsafe sexual practices among alcoholics or non-intravenous drug users (IDUs), a series of focus group discussions was conducted with 26 single, sexually active men and women in treatment for substance abuse. Results show that unsafe sexual practices in this subgroup may be explained by three factors: (1) intoxication, (2) negative perceptions of condoms, and (3) cognitive distortions. Furthermore, men's negative perceptions of condoms and women's concerns about not opposing men by fear of being rejected seem to be synergetic to bringing about the negative outcome. Implications for clinical practices are discussed.

Developing culture-specific interventions for Latinas to reduce HIV high-risk behaviors

Latina women are among the fastest-growing segments of the U.S. population to become infected with HIV. Health care providers must use culture-specific HIV prevention strategies and must address cultural roles and values of the Latin community to empower Latinas to reduce high-risk behaviors. Some Latinas adhere to their cultural traditions that place the female subservient to the male in the sexual relationship. A review of the literature reveals that skills-building, a group participatory tool that engages the individual to examine high-risk behaviors and provides methods to make behavior changes, and nurse counseling, which focuses on an individual's specific risk behaviors, are more effective modes of reducing high-risk behaviors in women than an information-only intervention.

Targeted prevention for people with HIV/AIDS: feasible and desirable?

People with HIV/AIDS are rarely chosen as a target group for prevention activities. In this paper we look at empirical and theoretical evidence for the feasibility and desirability of directing preventive interventions at HIV-positives. Research data on the behaviour and motivation of HIV-positives suggests that the differences between HIV-positives and HIV-negatives and those who are unaware of their HIV-status are not large. However, specific determinants of behaviour, such as responsibility for others or the risk of superinfection, have seldom been measured. Effective interventions targeting at HIV-positives and focussing on prevention are lacking. Fear of increased stigmatization has been used as an argument against focussing prevention activities at HIV-positives. Theoretically that argument is probably not correct: positive coping with HIV may invite positive reactions. The conclusion is that HIV-positives should be chosen as a special target group for additional planned preventive interventions. Because people need to be aware of their HIV status, testing and treatment sites are adequate settings. Effective interventions should be developed on the basis of theory and evidence about the specific determinants of risk behaviour of HIV-positives: protecting oneself for superinfection and protecting one's partner.
