HIV transmission risk behavior among men and women living with HIV in 4 cities in the United States.

Summary:Determining rates of HIV transmission risk behavior among HIV-positive individuals is a public health priority, especially as infected persons live longer because of improved medical treatments. Few studies have assessed the potential for transmission to the partners of HIV-positive persons who engage in high-risk activities. A total of 3723 HIV-infected persons (1918 men who have sex with men [MSM], 978 women, and 827 heterosexual men) were interviewed in clinics and community-based agencies in Los Angeles, Milwaukee, New York City, and San Francisco from June 2000 to January 2002 regarding sexual and drug use behaviors that confer risk for transmitting HIV. Less than one quarter of women and heterosexual men had 2 or more sexual partners, whereas 59% of MSM reported having multiple partners. Most unprotected vaginal and anal sexual activity took place in the context of relationships with other HIV-positive individuals. Approximately 19% of women, 15.6% of MSM, and 13.1% of heterosexual men engaged in unprotected vaginal or anal intercourse with partners who were HIV-negative or whose serostatus was unknown. The majority of sexually active participants disclosed their serostatus to all partners with whom they engaged in unprotected intercourse. An estimated 30.4 new infections (79.7% as a result of sexual interactions with MSM) would be expected among the sex partners of study participants during the 3-month reporting period. Eighteen percent of 304 participants who injected drugs in the past 3 months reported lending their used injection equipment to others. In addition to the more traditional approaches of HIV test counseling and of focusing on persons not infected, intensive prevention programs for persons with HIV infection are needed to stem the future spread of the virus.

Effects of a behavioral intervention to reduce risk of transmission among people living with HIV: The Healthy Living Project randomized controlled study

Context:The US Centers for Disease Control and Prevention (CDC) strongly recommend comprehensive risk counceling and services for people living with HIV (PLH); yet, there are no evidence-based counseling protocols. Objective:To examine the effect of a 15-session, individually delivered, cognitive behavioral intervention on a diverse sample of PLH at risk of transmitting to others. Design:This was a multisite, 2-group, randomized, controlled trial. Participants:Nine hundred thirty-six HIV-infected participants considered to be at risk of transmitting HIV of 3818 persons screened were randomized into the trial. Participants were recruited in Los Angeles, Milwaukee, New York, and San Francisco. Intervention:Fifteen 90-minute individually delivered intervention sessions were divided into 3 modules: stress, coping, and adjustment; safer behaviors; and health behaviors. The control group received no intervention until the trial was completed. Both groups completed follow-up assessments at 5, 10, 15, 20, and 25 months after randomization. Main Outcome Measure:Transmission risk, as measured by the number of unprotected sexual risk acts with persons of HIV-negative or unknown status, was the main outcome measure. Results:Overall, a significance difference in mean transmission risk acts was shown between the intervention and control arms over 5 to 25 months (χ2 = 16.0, degrees of freedom = 5; P = 0.007). The greatest reduction occurred at the 20-month follow-up, with a 36% reduction in the intervention group compared with the control group. Conclusion:Cognitive behavioral intervention programs can effectively reduce the potential of HIV transmission to others among PLH who report significant transmission risk behavior.

Throwing the dice: pregnancy decision-making among HIV-positive women in four U.S. cities.

CONTEXT Although AIDS-related deaths among U.S. women have decreased, the number of HIV-positive women, especially of reproductive age, has increased. A better understanding of the interaction between HIV and family planning is needed, especially as antiretroviral medications allow HIV-positive women to live longer, healthier lives. METHODS Qualitative methods were used to examine pregnancy decision-making among 56 HIV-positive women in four U.S. cities. Biomedical, individual and sociocultural themes were analyzed in groups of women, categorized by their pregnancy experiences and intentions. RESULTS Regardless of womens pregnancy experiences or intentions, reproductive decision-making themes included the perceived risk of vertical transmission, which was often overestimated; beliefs about vertical transmission risk reduction strategies; desire for motherhood; stigma; religious values; attitudes of partners and health care providers; and the impact of the mothers health and longevity on the child. Most women who did not want children after their diagnosis cited vertical transmission risk as the reason, and most of these women already had children. Those who became pregnant or desired children after their diagnosis seemed more confident in the efficacy of risk reduction strategies and often did not already have children. CONCLUSIONS Future studies may help clarify the relationship between factors that influence pregnancy decision-making among HIV-positive women. HIV-positive and at-risk women of childbearing age may benefit from counseling interventions sensitive to factors that influence infected womens pregnancy decisions.

Intricacies and inter-relationships between HIV disclosure and HAART: A qualitative study

This study aimed to understand whether and how highly active antiretroviral treatment (HAART) affects views and patterns of disclosure and how disclosure interacts with treatment decisions. One hundred and fifty-two HIV-positive adults (52 MSM, 56 women and 44 IDU men) from four US cities participated in two to three-hour, semi-structured interviews in 1998–99. Results indicate that HAART interacts with and shapes HIV disclosure issues in several ways. Medications may ‘out’ people living with HIV. Thus, in different settings (e.g. work, prisons, drug rehabs and public situations), some try to hide medications or modify dosing schedules, which can contribute to non-adherence, and affect sexual behaviours. Disclosure of HIV and/or HAART may also result in antagonism from others who hold negative attitudes and beliefs about HAART, potentially impeding adherence. Observable side effects of medications can also ‘out’ individuals. Conversely, medications may improve appearance, delaying or impeding disclosure. Some wait until they are on HAART and look ‘well’ before disclosing; some who look healthy as a result of medication deny being HIV-positive. Alternatively, HIV disclosure can lead to support that facilitates initiation of, and adherence to, treatment. HIV disclosure and adherence can shape one another in critical ways. Yet these interactions have been under-studied and need to be further examined. Interventions and studies concerning each of these domains have generally been separate, but need to be integrated, and the importance of relationships between these two areas needs to be recognized.

It's not just what you say: Relationships of HIV dislosure and risk reduction among MSM in the post-HAART era

Abstract In the post-HAART era, critical questions arise as to what factors affect disclosure decisions and how these decisions are associated with factors such as high-risk behaviors and partner variables. We interviewed 1,828 HIV-positive men who have sex with men (MSM), of whom 46% disclosed to all partners. Among men with casual partners, 41.8% disclosed to all of these partners and 21.5% to none. Disclosure was associated with relationship type, perceived partner HIV status and sexual behaviors. Overall, 36.5% of respondents had unprotected anal sex (UAS) with partners of negative/unknown HIV status. Of those with only casual partners, 80.4% had >1 act of UAS and 58% of these did not disclose to all partners. This 58% were more likely to self-identify as gay (versus bisexual), be aware of their status for <5 years and have more partners. Being on HAART, viral load and number of symptoms were not associated with disclosure. This study—the largest conducted to date of disclosure among MSM and one of the few conducted post-HAART—indicates that almost 1/5th reported UAS with casual partners without disclosure, highlighting a public health challenge. Disclosure needs to be addressed in the context of relationship type, partner status and broader risk-reduction strategies.

Medication Adherence and Sexual Risk Behavior among HIV-Infected Adults: Implications for Transmission of Resistant Virus

As more people are living long-term with HIV there are growing concerns about specific behaviors that can affect both personal and the public health. This study examined the relationship between antiretroviral therapy (ART) adherence and sexual risk behavior and their association with psychosocial and health factors among a diverse sample of 2,849 HIV-infected adults. Only 8.5% of the sample reported both non-adherence and sexual risk. Individuals were 46% more likely to report one of these risk outcomes when the other one was present and the presence of both outcomes was associated with an increased likelihood of having a detectable viral load. A simultaneous polytomous regression analysis revealed complex relationships among a range of psychosocial variables and the two primary behavioral risk outcomes. There is a need for targeted interventions and integration of mental health and substance use services into primary HIV care settings.

Insurance coverage, usual source of care, and receipt of clinically indicated care for comorbid conditions among adults living with human immunodeficiency virus.

Background and Objectives:Associations of insurance coverage and source of care with use of human immunodeficiency virus (HIV)-related health, mental health, and substance abuse services are examined in a large, diverse, highly active antiretroviral therapy-era cohort. Methods:Adults who were infected with HIV (n = 3818) were interviewed in clinics and community agencies in Los Angeles, Milwaukee, New York, and San Francisco regarding drug use behaviors, health status, and health care utilization. Results:Most participants were insured by Medicaid. During the previous 3 months, 90% of privately insured, 87% of publicly insured, and 78% of uninsured participants had visited any provider. Publicly and privately insured participants were similar in receipt of antiretrovirals, prophylaxis against Pneumocystis carinii pneumonia, substance abuse services, and antidepressants. Uninsured participants were less likely to receive antiretrovirals but were more likely to use substance abuse services. Participants with no usual source of care were less likely to receive PCP prophylaxis. Conclusions:A lack of insurance is associated with barriers to care, but the advantage of private over public coverage appears smaller than in previous studies. PCP prophylaxis, substance abuse treatment, and antidepressants remain markedly underutilized. Educational initiatives about these treatments targeting providers and patients are indicated.

The Female Condom: Attitudes and Experiences Among HIV-Positive Heterosexual Women and Men

ABSTRACT The female condom is a potentially effective method for the prevention of HIV, other sexually transmitted disease, and pregnancy. This study describes attitudes toward and experiences with the female condom of 89 HIV-positive individuals (n = 56 women; n = 33 men) reporting heterosexual behavior. Qualitative interviews were conducted to inform the design and implementation of a cognitive-behavioral risk-reduction and health-promotion intervention. Most respondents (n = 78) had seen or heard of the female condom. However, relatively few (n = 14 women; n = 5 men) had used it at least once. Reactions from both women and men across user groups, regardless of favorable or unfavorable attitude or experience with the female condom, centered around a similar set of factors: aesthetics, difficulties with the male condom, male partner reaction, beliefs about efficacy, and lack of training. These findings underscore the need for additional research and comprehensive education efforts aimed at both technical use and communication skills-building in order to realize the potential of the female condom as an alternative barrier method.
