RESUMO

The delivery of HIV risk assessment and behavioral counseling by clinicians in HIV clinical settings is one component in a comprehensive "positive prevention" strategy to help patients reduce their transmission risk behavior. Clinicians engage in behavioral prevention inconsistently, however, depending on whether patients are new to a practice or are established in regular care and on their attitudes and characteristics of their practices. We analyzed clinician reports of behavioral prevention delivered before and after participation in a large federal demonstration project of positive prevention interventions. The interventions that were part of this project were successful in increasing behavioral prevention among both new and returning patients. Prior to study interventions, clinicians reported counseling 69% of new patients and 52% of returning patients. In follow-up interviews 12 months after receiving training, clinicians reported delivering prevention messages to 5% more new patients and 9% of returning patients (both p<0.01). After 12 months, clinicians were more likely to engage in behavioral prevention if other providers in their sites were also involved. Clinicians agreeing that behavioral prevention was part of the clinic's mission were more likely to conduct it. The interventions were successful in mitigating the influence of provider attitudes precluding prevention delivery. Intervention strategies can help clinicians more consistently deliver behavioral prevention messages to their HIV-infected patients.

RESUMO

Given recent clinical trials establishing the safety and efficacy of adult medical male circumcision (MMC) in Africa, attention has now shifted to barriers and facilitators to programmatic implementation in traditionally non-circumcising communities. In this study, we attempted to develop a fuller understanding of the role of cultural issues in the acceptance of adult circumcision. We conducted four focus-group discussions with 28 participants in Mutoko, Zimbabwe, and 33 participants in Vulindlela, KwaZulu-Natal, South Africa, as well as 19 key informant interviews in both settings. We found the concept of male circumcision to be an alien practice, particularly as expressed in the context of local languages. Cultural barriers included local concepts of ethnicity, social groups, masculinity and sexuality. On the other hand, we found that concerns about the impact of HIV on communities resulted in willingness to consider adult male circumcision as an option if it would result in lowering the local burden of the epidemic. Adult MMC-promotional messages that create a synergy between understandings of both traditional and medical circumcision will be more successful in these communities.

RESUMO

As community-level interventions become more common in HIV prevention, processes such as community mobilization (CM) are increasingly utilized in public health programs and research. Project Accept, a multi-site community randomized controlled trial, is testing the hypothesis that CM coupled with community-based mobile voluntary counseling and testing and post-test support services will alter community norms and reduce the incidence of HIV. By using a multiple-case study approach, this qualitative study identifies seven major community mobilization strategies used in Project Accept, including stakeholder buy-in, formation of community coalitions, community engagement, community participation, raising community awareness, involvement of leaders, and partnership building, and describes three key elements of mobilization success.

RESUMO

BACKGROUND: Despite high rates of patient satisfaction with emergency department (ED) HIV testing, acceptance varies widely. It is thought that patients who decline may be at higher risk for HIV infection, thus we sought to better understand patient acceptance and refusal of ED HIV testing. METHODS: In-depth interviews with fifty ED patients (28 accepters and 22 decliners of HIV testing) in three ED HIV testing programs that serve vulnerable urban populations in northern California. RESULTS: Many factors influenced the decision to accept ED HIV testing, including curiosity, reassurance of negative status, convenience, and opportunity. Similarly, a number of factors influenced the decision to decline HIV testing, including having been tested recently, the perception of being at low risk for HIV infection due to monogamy, abstinence or condom use, and wanting to focus on the medical reason for the ED visit. Both accepters and decliners viewed ED HIV testing favorably and nearly all participants felt comfortable with the testing experience, including the absence of counseling. While many participants who declined an ED HIV test had logical reasons, some participants also made clear that they would prefer not to know their HIV status rather than face psychosocial consequences such as loss of trust in a relationship or disclosure of status in hospital or public health records. CONCLUSIONS: Testing for HIV in the ED as for any other health problem reduces barriers to testing for some but not all patients. Patients who decline ED HIV testing may have rational reasons, but there are some patients who avoid HIV testing because of psychosocial ramifications. While ED HIV testing is generally acceptable, more targeted approaches to testing are necessary for this subgroup.

RESUMO

BACKGROUND: Study-based global health interventions, especially those that are conducted on an international or multi-site basis, frequently require site-specific adaptations in order to (1) respond to socio-cultural differences in risk determinants, (2) to make interventions more relevant to target population needs, and (3) in recognition of 'global health diplomacy' issues. We report on the adaptations development, approval and implementation process from the Project Accept voluntary counseling and testing, community mobilization and post-test support services intervention. METHODS: We reviewed all relevant documentation collected during the study intervention period (e.g. monthly progress reports; bi-annual steering committee presentations) and conducted a series of semi-structured interviews with project directors and between 12 and 23 field staff at each study site in South Africa, Zimbabwe, Thailand and Tanzania during 2009. Respondents were asked to describe (1) the adaptations development and approval process and (2) the most successful site-specific adaptations from the perspective of facilitating intervention implementation. RESULTS: Across sites, proposed adaptations were identified by field staff and submitted to project directors for review on a formally planned basis. The cross-site intervention sub-committee then ensured fidelity to the study protocol before approval. Successfully-implemented adaptations included: intervention delivery adaptations (e.g. development of tailored counseling messages for immigrant labour groups in South Africa) political, environmental and infrastructural adaptations (e.g. use of local community centers as VCT venues in Zimbabwe); religious adaptations (e.g. dividing clients by gender in Muslim areas of Tanzania); economic adaptations (e.g. co-provision of income generating skills classes in Zimbabwe); epidemiological adaptations (e.g. provision of 'youth-friendly' services in South Africa, Zimbabwe and Tanzania), and social adaptations (e.g. modification of terminology to local dialects in Thailand: and adjustment of service delivery schedules to suit seasonal and daily work schedules across sites). CONCLUSIONS: Adaptation selection, development and approval during multi-site global health research studies should be a planned process that maintains fidelity to the study protocol. The successful implementation of appropriate site-specific adaptations may have important implications for intervention implementation, from both a service uptake and a global health diplomacy perspective.

RESUMO

To support expanded prevention services for people living with HIV, the US Health Resources and Services Administration (HRSA) sponsored a 5-year initiative to test whether interventions delivered in clinical settings were effective in reducing HIV transmission risk among HIV-infected patients. Across 13 demonstration sites, patients were randomized to one of four conditions. All interventions were associated with reduced unprotected vaginal and/or anal intercourse with persons of HIV-uninfected or unknown status among the 3,556 participating patients. Compared to the standard of care, patients assigned to receive interventions from medical care providers reported a significant decrease in risk after 12 months of participation. Patients receiving prevention services from health educators, social workers or paraprofessional HIV-infected peers reported significant reduction in risk at 6 months, but not at 12 months. While clinics have a choice of effective models for implementing prevention programs for their HIV-infected patients, medical provider-delivered methods are comparatively robust.

RESUMO

Gregory M. Herek, PhD, made an important professional contribution through his service as chair of the Scientific Review Committee of the Wayne F. Placek Fund of the American Psychological Foundation (APF). The scholars funded by this grant benefited from the prestige of the grant, which provided an important credential for early career professional development. Many of them went on to become significant researchers in the field of sexual and gender minorities. The studies funded by the Placek Grant also had important political and social effects, such as on legalizing adoption by lesbian and gay parents, passage of same-sex marriage, and demonstrating that lesbians and gay men were at elevated risk for physical health problems. The purpose of the present article is to document the history and impact of the Placek Grant and to describe Greg Herek's central role in this grant program.

RESUMO

BACKGROUND: Disparities in the use of antiretroviral therapy (ART) for HIV disease have been documented across race, gender, and substance use groups. OBJECTIVE: The current analysis compares self-reported reasons for never taking or stopping ART among a diverse sample of men and women living with HIV. DESIGN: Cross-sectional interview. PARTICIPANTS: HIV + (N = 3,818) adults, 968 of whom reported discontinuing or never using ART. MEASUREMENTS: Computerized self-administered and interviewer-administered self-reported demographic and treatment variables, including gender, race, ethnicity, CD4 count, detectable viral load, and reported reasons for not taking antiretroviral therapy. RESULTS: Despite equivalent use of ART in the current sample, African-American respondents were 1.7 times more likely to report wanting to hide their HIV status and 1.7 times more likely to report a change in doctors/clinics as reasons for stopping ART (p = .049, and p = .042) and had odds 4.5 times those of non-African Americans of reporting waiting for viral marker counts to worsen (p = < .0001). There was a lower tendency (OR = 0.4) for women to endorse concerns of keeping their HIV status hidden as a reason for stopping ART compared to men (p = .003). Although those with an IDU history were less likely to be on ART, no differences in reasons for stopping or never initiating ART were found between those with and without an IDU history. CONCLUSIONS: A desire to conceal HIV status as well as a change in doctors/clinics as reasons for discontinuing ART were considerably more common among African Americans, suggesting that perceived HIV/AIDS stigma is an obstacle to maintenance of treatment. Findings also indicate differences in reasons for stopping ART by gender and a perceived desire to wait for counts to worsen as a reason for not taking ART by African Americans, regardless of detectable viral load, CD4 count, age, education, employment, sexual orientation, and site.

RESUMO

Questions remain regarding the clinical utility of psychological interventions for HIV-positive persons because randomized controlled trials have utilized stringent inclusion criteria and focused extensively on gay men. The present randomized controlled trial examined the efficacy of a 15-session, individually delivered cognitive-behavioral intervention (n = 467) compared to a wait-list control (n = 469) in a diverse sample of HIV-positive persons who reported HIV transmission risk behavior. Five intervention sessions that dealt with executing effective coping responses were delivered between baseline and the 5 months post-randomization. Additional assessments were completed through 25 months post-randomization. Despite previously documented reductions in HIV transmission risk, no intervention-related changes in psychosocial adjustment were observed across the 25-month investigation period. In addition, there were no intervention effects on psychosocial adjustment among individuals who presented with mild to moderate depressive symptoms. More intensive mental health interventions may be necessary to improve psychosocial adjustment among HIV-positive individuals.

RESUMO

Risk reductions behaviors are especially important during acute/early HIV infection, a period of high transmission risk. We examined how sexual behaviors changed following diagnosis of acute/early HIV infection. Twenty-eight individuals completed structured surveys and in-depth interviews shortly after learning of their infection and 2 months later. Quantitative analyses revealed significant changes after diagnosis, including reductions in total partners and decreases in the proportion of unprotected sex acts occurring with uninfected partners (serosorting). Qualitative findings indicated that these changes were motivated by concerns about infecting others. However, participants were less successful at increasing the frequency with which they used condoms. These results suggest that the initial diagnosis with HIV may constitute an important component of interventions to promote risk reduction during the acute/early stages of the disease.

RESUMO

Acute/early HIV infection is a period of heightened HIV transmission and a window of opportunity for intervention to prevent onward disease transmission. The NIMH Multisite Acute HIV Infection (AHI) Study was an exploratory initiative aimed at determining the feasibility of recruiting persons with AHI into research, assessing their psychosocial and behavioral characteristics, and examining short-term changes in these characteristics. This paper reports on lessons learned in the study, including: (1) the need to establish the cost-effectiveness of AHI testing; (2) challenges to identifying persons with AHI; (3) the need to increase awareness of acute-phase HIV transmission risks; (4) determining the goals of behavioral interventions following AHI diagnosis; and (5) the need for "rapid response" public health systems that can move quickly enough to intervene while persons are still in the AHI stage. There are untapped opportunities for behavioral and medical science collaborations in these areas that could reduce the incidence of HIV infection.

RESUMO

Acute/early HIV infection plays a critical role in onward HIV transmission. Detection of HIV infections during this period provides an important early opportunity to offer interventions which may prevent further transmission. In six US cities, persons with acute/early HIV infection were identified using either HIV RNA testing of pooled sera from persons screened HIV antibody negative or through clinical referral of persons with acute or early infections. Fifty-one cases were identified and 34 (68%) were enrolled into the study; 28 (82%) were acute infections and 6 (18%) were early infections. Of those enrolled, 13 (38%) were identified through HIV pooled testing of 7,633 HIV antibody negative sera and 21 (62%) through referral. Both strategies identified cases that would have been missed under current HIV testing and counseling protocols. Efforts to identify newly infected persons should target specific populations and geographic areas based on knowledge of the local epidemiology of incident infections.

RESUMO

Acute/early HIV infection is a period of high risk for HIV transmission. Better understanding of behavioral aspects during this period could improve interventions to limit further transmission. Thirty-four participants with acute/early HIV infection from six US cities were assessed with the Mini International Diagnostic Interview, Beck Depression Inventory II, State-Trait Anxiety Inventory, Brief COPE, and an in-depth interview. Most had a pre-HIV history of alcohol or substance use disorder (85%); a majority (53%) had a history of major depressive or bipolar disorder. However, post-diagnosis coping was predominantly adaptive, with only mild to moderate elevations of anxious or depressive mood. Respondents described challenges managing HIV in tandem with pre-existing substance abuse problems, depression, and anxiety. Integration into medical and community services was associated with adaptive coping. The psychiatric context of acute/early HIV infection may be a precursor to infection, but not necessarily a barrier to intervention to reduce forward transmission of HIV among persons newly infected.

RESUMO

Acute/early HIV infection is a period of high HIV transmission. Consequently, early detection of HIV infection and targeted HIV prevention could prevent a significant proportion of new transmissions. As part of an NIMH-funded multisite study, we used in-depth interviews to explore understandings of acute HIV infection (AHI) among 34 individuals diagnosed with acute/early HIV infection in six US cities. We found a marked lack of awareness of AHI-related acute retroviral symptoms and a lack of clarity about AHI testing methods. Most participants knew little about the meaning and/or consequences of AHI, particularly that it is a period of elevated infectiousness. Over time and after the acute stage of infection, many participants acquired understanding of AHI from varied sources, including the Internet, HIV-infected friends, and health clinic employees. There is a need to promote targeted education about AHI to reduce the rapid spread of HIV associated with acute/early infection within communities at risk for HIV.

RESUMO

The authors examined associations between psychosocial variables (coping self-efficacy, social support, and cognitive depression) and subjective health status among a large national sample (N = 3,670) of human immunodeficiency virus (HIV)-positive persons with different sexual identities. After controlling for ethnicity, heterosexual men reported fewer symptoms than did either bisexual or gay men and heterosexual women reported fewer symptoms than did bisexual women. Heterosexual and bisexual women reported greater symptom intrusiveness than did heterosexual or gay men. Coping self-efficacy and cognitive depression independently explained symptom reports and symptom intrusiveness for heterosexual, gay, and bisexual men. Coping self-efficacy and cognitive depression explained symptom intrusiveness among heterosexual women. Cognitive depression significantly contributed to the number of symptom reports for heterosexual and bisexual women and to symptom intrusiveness for lesbian and bisexual women. Individuals likely experience HIV differently on the basis of sociocultural realities associated with sexual identity. Further, symptom intrusiveness may be a more sensitive measure of subjective health status for these groups.

RESUMO

Cocaine, crack, and methamphetamine are stimulants that promote autonomic nervous system activation. Although these stimulants may have immunomodulatory effects, relatively few studies have examined this possibility. The present cross-sectional investigation utilized baseline data from 127 HIV-positive individuals on anti-retroviral therapy (ART) that were enrolled in a randomized controlled trial. The goal of this study was to examine whether stimulant use is independently associated with immune activation and indices of tryptophan degradation. Forty-four participants reported using stimulants 2-3 times a month or more (i.e., monthly stimulant use) and a sub-set of these (n=27) reported using stimulants once a week or more (i.e., weekly stimulant use) during the past three months. These stimulant-using groups were compared to a group of participants who reported no stimulant use (n=83) during the past three months. Results indicated that individuals who reported either monthly or weekly stimulant use displayed elevated neopterin, a measure of immune activation. Those who reported weekly stimulant use also displayed a markedly elevated HIV viral load and lower tryptophan levels. Even after controlling for self-reported ART non-adherence, weekly stimulant use was independently associated with higher neopterin, elevated HIV viral load, and lower tryptophan. To our knowledge, this is the first study to observe that stimulant use may independently promote immune activation and tryptophan degradation among HIV-positive persons on ART. Further research is needed to replicate these findings and examine the plausible bio-behavioral pathways that may account for the effects of stimulant use on HIV disease markers and depleted tryptophan.

RESUMO

Unprotected sexual intercourse remains a primary mode of HIV transmission in the United States. We found that receipt of services to reduce HIV transmission-risk behaviors was low among 3787 HIV-infected individuals and that men who have sex with men were especially unlikely to receive these services even though they were more likely to report unprotected sexual intercourse with seronegative and unknown serostatus casual partners. Greater efforts should be made to ensure that prevention counseling is delivered to all HIV-infected persons, especially men who have sex with men.

RESUMO

Retaining high-risk individuals is critical for HIV prevention trials. The current analyses examined predictors of trial dropout among HIV-infected men and women in a multi-site HIV prevention trial. Results indicated that dropouts (n = 74) were more likely to be younger, depressed, and not taking antiretroviral therapy (ART) than those who continued (n = 815). No other background, substance use, or transmission risk differences were found, suggesting no direct evidence of dropout bias on key outcomes. Efforts may be warranted for early detection and treatment of depression and for improving retention of younger participants and those not on ART.

RESUMO

OBJECTIVES: The present investigation sought to determine the extent to which demographic characteristics, illness-related burdens, alcohol and other substance use, and psychosocial factors are independently associated with suicidal ideation in HIV-positive individuals. DESIGN: HIV-positive individuals in four US cities (San Francisco, Los Angeles, Milwaukee, and New York City) were screened between July 2000 and January 2002 for recruitment into a randomized behavioral prevention trial. Utilizing data from this screening visit, rates and correlates of suicidal ideation were examined in a diverse sample of 2909 HIV-positive individuals. METHODS: Using binary logistic regression study sites, demographic characteristics, illness-related burdens, alcohol and substance use, and psychosocial factors were entered as predictors of suicidal ideation. This cross-sectional model thus examined the independent effects of each factor. RESULTS: Approximately one-fifth (19%) of participants reported thoughts of suicide in the past week. We observed that participants who were not heterosexual, rated HIV-related symptoms and medication side effects as more severe, reported regular marijuana use, and described elevated affective symptoms of depression were those who were more likely to report suicidal ideation. Conversely, participants who identified as Hispanic/Latino, individuals in a primary romantic relationship, and those who reported greater self-efficacy for coping were less likely to report suicidal ideation. CONCLUSION: Suicidal ideation among HIV-positive individuals is relatively common and is associated with multiple factors. These independent correlates may assist with identifying HIV-positive individuals who are at increased risk of suicidal ideation so that they may be assessed regularly and referred for psychological treatment when appropriate.

RESUMO

OBJECTIVE: A substantial minority of HIV-positive individuals have comorbid affective or substance use disorders, which can interfere with effective medical management. The present study examined the associations among affect regulation, substance use, non-adherence to anti-retroviral therapy (ART), and immune status in a diverse sample of HIV-positive persons. METHODS: A total of 858 HIV-positive participants self-reporting risk of transmitting HIV were enrolled in a randomized behavioral prevention trial and provided baseline blood samples to measure T-helper (CD4+) counts and HIV viral load. RESULTS: Among individuals on ART, regular stimulant users had a five-fold (0.70 log10) higher HIV viral load than those who denied regular stimulant use. The association between regular stimulant use and elevated HIV viral load remained after accounting for demographics, differences in CD4+ counts, and polysubstance use. In the final model, 1 unit increase in affect regulation (decreased severity of depressive symptoms as well as enhanced positive states of mind) was associated with a 23% decrease in the likelihood of reporting regular stimulant use and 15% decrease in the likelihood of being classified as nonadherent to ART. Regular stimulant users, in turn, were more than twice as likely to be nonadherent to ART. Even after accounting for the effects of nonadherence and CD4+ counts, regular stimulant use was independently associated with 50% higher HIV viral load. CONCLUSIONS: Increased mental health treatment as well as more intensive referrals to substance abuse treatment or 12-step self-help groups may be crucial to assist stimulant users with more effectively managing treatment for HIV/AIDS.
