Development of an HIV risk reduction intervention for older seropositive African American men

What is the added value of incorporating pleasure in sexual health interventions? A systematic review and meta-analysis

Despite billions of dollars invested into Sexual and Reproductive Health and Rights (SRHR) efforts, the effect of incorporating sexual pleasure, a key driver of why people have sex, in sexual health interventions is currently unclear. We carried out a systematic review and meta-analysis following PRISMA guidelines across 7 databases for relevant articles published between 1 January 2005-1 June, 2020. We included 33 unique interventions in our systematic review. Eight interventions reporting condom use outcomes were meta-analyzed together with a method random effects model. Quality appraisal was carried out through the Cochrane Collaborations' RoB2 tool. This study was pre-registered on Prospero (ID: CRD42020201822). We identified 33 unique interventions (18886 participants at baseline) that incorporate pleasure. All included interventions targeted HIV/STI risk reduction, none occurred in the context of pregnancy prevention or family planning. We find that the majority of interventions targeted populations that authors classified as high-risk. We were able to meta-analyze 8 studies (6634 participants at baseline) reporting condom use as an outcome and found an overall moderate, positive, and significant effect of Cohen's d = 0·37 (95% CI 0·20-0·54, p < 0·001; I2 = 48%; τ2 = 0·043, p = 0·06). Incorporating sexual pleasure within SRHR interventions can improve sexual health outcomes. Our meta-analysis provides evidence about the positive impact of pleasure-incorporating interventions on condom use which has direct implications for reductions in HIV and STIs. Qualitatively, we find evidence that pleasure can have positive effects across different informational and knowledge-based attitudes as well. Future work is needed to further elucidate the impacts of pleasure within SRHR and across different outcomes and populations. Taking all the available evidence into account, we recommend that agencies responsible for sexual and reproductive health consider incorporating sexual pleasure considerations within their programming.

Effectiveness of HIV Stigma Interventions for Men who have Sex with Men (MSM) With and Without HIV in the United States: A Systematic Review and Meta-Analyses

Stigma may contribute to HIV disparities for men who have sex with men (MSM). This systematic review quantified the effects of HIV stigma interventions for MSM on stigma and sex risk. We conducted a systematic search to identify US-based studies published between 2000 and June 2019 focused on HIV and MSM, and either measured stigma pre-post or included a stigma intervention component. Twenty-nine articles, representing 26 unique studies met inclusion criteria. Random effect models showed no intervention effect for reducing stigma and a non-significant increase in HIV testing. Significant decreases in condomless sex with males, condomless sex with females, and substance-influenced sex were found. Few intervention studies measured stigma pre-post. Findings suggest that including a stigma reduction component in interventions can improve HIV testing and reduce sex risk for MSM. Developing interventions to address stigma may be important in decreasing HIV infection among MSM and ending the HIV epidemic.

Social Cognitive Theory as a Theoretical Framework to Predict Sexual Risk Behaviors among Older Adults

OBJECTIVES

Older adults vary in their safe and unsafe sexual behaviors. While researchers are beginning to understand more about the sexual and intimate expression of older adults, only recently are they beginning to understand how older adults make decisions about sexual risk. Bandura's social cognitive theory offers a frame for understanding how self-efficacy, environmental factors, and goal motivation are related to sexual risk behaviors for older adults, including the interplay between these variables.

METHODS

Using a diverse sample of older adults (n = 720) age 50+ years, social cognitive theory was modeled to determine the relationship between environment variables (age, gender, and sexual health conversations with practitioners), behavioral variables (self-efficacy), and cognitive variables (importance of sexual wellness goals) with the outcome variable of sexual risk behaviors.

RESULTS

Self-efficacy had an indirect effect on sexual risk via sexual wellness goal motivation. Healthcare provider conversations had both direct and indirect effects on older adults' sexual risk through sexual wellness goal motivation. Models were similarly predictive for older men and women.

CONCLUSIONS

Sexual risk behaviors among older adults are more influenced by environmental factors in their healthcare settings and their perception and prioritization of sexual wellness goals.

CLINICAL IMPLICATIONS

Providers play a key role in initiating and maintaining sexual health discussions with older patients, potentially mitigating sexual risk and bolstering self-efficacy.

Barriers and Facilitators to Engaging African American Men Who Have Sex With Men in the HIV Care Continuum: A Theory-Based Qualitative Study

African American men who have sex with men (MSM) have high rates of HIV, but interventions are needed to address their low rates of engagement in the HIV care continuum. To identify modifiable factors potentially affecting such engagement, we conducted qualitative interviews guided by the Theory of Planned Behavior with 27 African American MSM who had participated in an HIV risk-reduction intervention trial. Qualitative analyses resulted in four overarching themes: stigma, concerns with health care providers (HCPs), social support, and logistical issues. Facilitators of care continuum engagement included reassurance about health, feeling and looking better, receiving treatment, avoiding infecting others, good relations with HCP, and social support. Barriers included HIV stigma, concerns about confidentiality, negative perceptions of HCP, convenience and availability of testing/treatment facilities, cost, and lack of social support. Efforts to improve African American MSM HIV care continuum engagement should focus on individual and health care system changes.

Condom use intentions mediate the relationships between psychosocial constructs and HIV sexual risk behavior in young Black men who have sex with men

HIV prevention interventions that reduce sexual risk behaviors among young Black men who have sex with men (YBMSM), the most severely affected population in the United States, are critical for reducing disparities in HIV infection. However, there are few theory-based sexual risk reduction interventions designed specifically for YBMSM. This study tested the applicability of the Integrated Behavioral Model (IBM), which theorizes that behavioral intentions mediate the relationship between psychosocial constructs and health behavior on condomless anal intercourse (CAI) among YBMSM. To test key constructs of the IBM, analyses were conducted with baseline data from the HealthMpowerment (HMP) randomized controlled trial. Logistic regression was used to examine the relationships between condom use self-efficacy, norms, attitudes, intentions, and environmental constraints, and CAI. Mediation analysis was conducted to determine if condom use intentions mediated the relationship between psychosocial constructs (i.e., condom use self-efficacy, norms, and attitudes) and CAI. Overall 55.7% reported one or more acts of CAI with a male partner in the past 3 months. Those who reported CAI in the 3 months prior to the baseline survey reported lower self-efficacy for condom use, lower condom use norms, more negative attitudes toward condom use, and lower condom use intentions at baseline than those who reported no CAI. In mediation analysis, the relationships between CAI and self-efficacy for condom use (estimated indirect effect = -0.004 (SE = 0.002)), condom use norms (-0.002 (SE = 0.001)) and attitudes toward condom use (-0.005 (SE = 0.002)) were mediated by condom use intentions. This study applied the IBM to sexual risk behavior among a sample of YBMSM. Results indicate that the relationships between condom use self-efficacy, norms, and attitudes, and CAI were mediated by condom use intentions. Future theory-informed interventions should focus on increasing self-efficacy for condom use, condom use norms, attitudes toward condom use, and condom use intentions to reduce CAI among YBMSM.

Condom use social norms and self-efficacy with different kinds of male partners among Chinese men who have sex with men: results from an online survey

Background

Social norms and self-efficacy play important roles in promoting consistent condom use among men who have sex with men (MSM). Few studies have investigated the association between social norms, self-efficacy and consistent condom use with different kinds of male partners among MSM. We conducted an online survey of MSM to evaluate this in China.

Methods

A cross-sectional online survey was conducted in 2015. Participants completed a validated questionnaire covering socio-demographic information, consistent condom use, condom use social norms and self-efficacy. Eligible participants were 16 or older, born biologically as a male, engaged in anal sex with a man at least once during their lifetime, engaged in condomless anal or vaginal sex in the last three months. In this study, we further restricted to people who had sex with male partners in the last three months. Participants were classified into three groups: engaged in sex only with regular partners, engaged in sex only with casual partners and engaged in sex with both regular partners and casual partners.

Results

Participants were recruited from 32 provinces in China. Among 1057 participants, 451(42.7%), 217(20.5%), and 389(36.8%) engaged in sex with regular partners only, casual partners only and both types in the last three months, respectively. Men engaged in sex only with regular partners in the last three months had a higher condom use self-efficacy than with other two types of partners (P < 0.01). Both social norms (regular partners: adjusted OR:1.59, 95% CI: 0.97–2.60; casual partners: adjusted OR: 1.58, 95% CI: 1.19–2.09; both types: adjusted OR: 1.48, 95% CI: 1.13–1.95) and self-efficacy (regular partners: adjusted OR: 2.88, 95% CI: 1.59–5.22; casual partners: adjusted OR: 2.35, 95% CI: 1.69–3.26; both types: adjusted OR: 2.45, 95% CI: 1.81–3.32) were positively associated with consistent condom use. No interaction effect was detected between condom social norms and self-efficacy on consistent condom use among Chinese MSM (p > 0.05).

Conclusions

Both social norms and self-efficacy were positively correlated with consistent condom use with any types of partners among Chinese MSM. Tailored interventions that aimed to improve social norms and self-efficacy has the potential to improve overall condom use among Chinese MSM.

Effects of cognitive-behavioural therapy on anxiety, depression and condom use in people with HIV in Mexico City: a pilot study

Anxiety and depression in people living with HIV (PLWH) are negatively associated with healthy sexual behaviours. We pilot-tested a Cognitive-Behavioural Therapy (CBT)-based intervention to reduce anxiety and depression, aimed to increase serostatus disclosure to sexual partners, quality of sexual life (QoSL) and condom use. The study had a single-case experimental design (AB) with follow-up measures. Eleven PLWH with moderate/severe anxiety/depression received six-module CBT intervention delivered in ten one-hour individual weekly sessions. Anxiety, depression, consistent/correct condom use and QoSL were measured. Depression and anxiety decreased after the intervention (depression baseline [BL] Mdn = 21, final [F] Mdn = 3, z = -2.934, p = .003; anxiety BL Mdn = 30, F Mdn = 4, z = -2.941, p = .003). QoSL improved (BL Mdn = 28, F Mdn = 13, z = -2.625, p = .009), along with participants' ability to use condoms (57.14 vs.100, z = -2.937, p = .003). Effect size was large, changes were maintained at follow-up measurements. The CBT intervention had positive effects in reducing anxiety and depression, which could facilitate the acquisition of healthy sexual behaviours. Further studies are important to clarify the benefits of targeting emotional variables to improve wellbeing and prevention behaviours in PLWH.

Physical and Psychological Abuse among Seropositive African American MSM 50 Aged Years and Older

Little is known about abuse experienced among African American men who have sex with men (MSM) who are 50 years and older. A series of focus groups were conducted to examine perspectives of seropositive African American MSM age 50 years and older who reported experiencing some form of psychological or physical abuse. Thirty African American MSM were divided into four focus groups and four themes emerged: "Fear Being Gay," "No One Else to Love Me," "Nowhere to Turn," and "Sexual Risk & Control." The data suggest there is a need to develop culturally tailored interventions for this population.

HIV/STI Prevention Interventions: A Systematic Review and Meta-analysis

Behavioral interventions can prevent the transmission of HIV and sexually transmitted infections. This systematic review and meta-analysis assesses the effectiveness and quality of available evidence of HIV prevention interventions for people living with HIV in high-income settings. Searches were conducted in MEDLINE, EMBASE, PsycINFO, and CDC Compendium of Effective Interventions. Interventions published between January, 1998 and September, 2015 were included. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Forty-six articles and 63 datasets involving 14,096 individuals met inclusion criteria. Included articles were grouped by intervention type, comparison group and outcome. Few of these had high or moderate quality of evidence and statistically significant effects. One intervention type, group-level health education interventions, were effective in reducing HIV/STI incidence when compared to attention controls. A second intervention type, comprehensive risk counseling and services, was effective in reducing sexual risk behaviors when compared to both active and attention controls. All other intervention types showed no statistically significant effect or had low or very low quality of evidence. Given that the majority of interventions produced low or very low quality of evidence, researchers should commit to rigorous evaluation and high quality reporting of HIV intervention studies.

Women 50 and Older and HIV: Prevention and Implications for Health Care Providers

The current article discusses the importance of implementing HIV and AIDS education, prevention, and intervention programs that are tailored to women 50 and older and to determine HIV risk factors for this population. A literature search was performed, resulting in 41 relevant articles. The literature underscored the significance of increasing awareness of HIV/AIDS, particularly among older women. HIV risk behaviors and the effect that these behaviors have on HIV transmission and prevention among women 50 and older are described. Prior research findings identified risk categories of older women that may contribute to the transmission of HIV among this particular population, including heterosexual relations, perceived HIV risk, ageism and HIV transmission, biological factors, transfusions, sexual enhancement aids, and health care providers and prevention messages. In addition, previous findings indicate that health care providers have not traditionally targeted women 50 and older for HIV prevention. Health care providers should incorporate discussion of HIV risk and transmission during clinic visits and implement prevention programs that target this population.

Qualitative Perspectives about Living with HIV from Seropositive African American MSM Aged 50 years and Older

It has nearly been more than three decades; yet, the research on aging seropositive African American men who have sex with men (MSM) is scarce. Exploring issues for an aging population of seropositive MSM is critical given that earlier epidemiological data suggested that by 2015, half of the AIDS cases will be in adults aged 50 years and older. A qualitative approach with the aim to examine perspectives about HIV risk from a group of seropositive African American MSM 50 years of age and older was conducted. Two separate focus groups with a total N  =  30 were conducted. Four themes emerged: feeling left out, no place to call home, not a priority, and no one to grow older with.

A mixed methods study of health and social disparities among substance-using African American/Black men who have sex with men

African American/Black men who have sex with men (MSM) in the U.S. experience health and social disparities at greater rates than MSM of other races/ethnicities, including HIV infection and substance use. This mixed methods paper presents: 1) a quantitative examination of health and social disparities among a sample of substance-using African American/Black MSM (N=108), compared to Caucasian/White MSM (N=250), and 2) in-depth qualitative data from a subsample of African American/Black MSM (N=21) in order to contextualize the quantitative data. Findings indicate that compared to Caucasian/White MSM, African American/Black MSM experienced a wide range of health and social disparities including: substance use and dependence; buying, trading or selling sex; educational attainment; employment; homelessness; identifying as gay; HIV status; arrest history; social support; and satisfaction with one's living situation. Qualitative data suggests that structural interventions that address homophobia and the social environment would be likely to mitigate many of the health and social disparities experienced by African American/Black MSM.

Interventions to increase condom use among middle-aged and older adults: A systematic review of theoretical bases, behaviour change techniques, modes of delivery and treatment fidelity

This systematic review collates, examines and syntheses condom use interventions for middle-aged and older adults. Associations between effectiveness and theoretical basis, behaviour change techniques, mode of delivery and treatment fidelity were explored. Five interventions were included; one was effective. Compared to interventions with non-significant findings, the effective telephone-administered intervention used theory to a greater extent, had a higher number of behaviour change techniques and employed more treatment fidelity strategies. There is a need to develop theory-based interventions targeting condom use among this population and evaluate these in randomised controlled trials that are rigorously designed and reported. Health psychologists have a key role in this endeavour.

A Qualitative Approach to Increasing HIV Prevention in Primary Care Settings for Older Adults: Perspectives From Primary Care Providers

The purpose of this research was to explore primary care providers' willingness and ability to increase HIV prevention efforts among older adults and to gain recommendations for improving HIV prevention in primary care settings. Data were collected through 24 semistructured interviews with primary care providers. The results of the study reveal that the majority of providers find it necessary to increase HIV prevention efforts in primary care settings and are willing to do so; however, they cannot do so without assistance. Providers suggested strategies to increase HIV prevention in primary care, for instance, expanding the use of electronic reminders to include HIV prevention and increasing collaboration among providers of different specialties. As a result of the interviews, additional recommendations for increasing HIV prevention have been identified. These findings will aid in improving the quality of care provided to individuals older than 50 in primary care settings.

On the Efficacy and Mediation of a One-on-One HIV Risk-Reduction Intervention for African American Men Who Have Sex with Men: A Randomized Controlled Trial

We examined the efficacy and mediation of Being Responsible for Ourselves (BRO), an HIV/STI risk-reduction intervention for African American men who have sex with men (MSM), the population with the highest HIV-diagnosis rate in the US. We randomized African American MSM to one of two interventions: BRO HIV/STI risk-reduction, targeting condom use; or attention-matched control, targeting physical activity and healthy diet. The interventions were based on social cognitive theory, the reasoned-action approach, and qualitative research. Men reporting anal intercourse with other men in the past 90 days were eligible and completed pre-intervention, immediately post-intervention, and 6 and 12 months post-intervention surveys. Of 595 participants, 503 (85 %) completed the 12-month follow-up. Generalized-estimating-equations analysis indicated that, compared with the attention-matched control intervention, the BRO intervention did not increase consistent condom use averaged over the 6- and 12-month follow-ups, which was the primary outcome. Although BRO did not affect the proportion of condom-protected intercourse acts, unprotected sexual intercourse, multiple partners, or insertive anal intercourse, it did reduce receptive anal intercourse compared with the control, a behavior linked to incident HIV infection. Mediation analysis using the product-of-coefficients approach revealed that although BRO increased seven of nine theoretical constructs it was designed to affect, it increased only one of three theoretical constructs that predicted consistent condom use: condom-use impulse-control self-efficacy. Thus, BRO indirectly increased consistent condom use through condom-use impulse-control self-efficacy. In conclusion, although BRO increased several theoretical constructs, most of those constructs did not predict consistent condom use; hence, the intervention did not increase it. Theoretical constructs that interventions should target to increase African American MSM’s condom use are discussed.

Understanding of the risk of HIV infection among the elderly in Ga-Rankuwa, South Africa

The literature pertaining to the elderly shows that HIV infection among this population is on the increase, suggesting that the elderly population engages in activities risky for HIV infection. Reports on such behaviour include frequent sexual relations with much younger people and having multiple partners. A study was carried out in Ga-Rankuwa, a black township in Gauteng Province, South Africa to explore and describe the understanding of these elderly people regarding their risks of HIV infection and AIDS. Using a qualitative, exploratory design, three focus-group interviews were conducted with 32 women aged over 50 years. Findings revealed that older persons have knowledge about transmission of HIV infection and AIDS. However, a few had misconceptions as to how HIV infection is transmitted, as they believed that poor nutrition and sharing facilities play a role. Knowledge of mechanisms of protecting themselves against infection, such as use of a condom during coitus and wearing gloves when caring for infected family members, was also evident. The elderly indicated that they would prefer an older person, who they could identify with, to educate them more about HIV infection and AIDS. Although majority of participants had knowledge of how HIV is transmitted, and issues that put them at risk of transmission, a few the older persons had misconceptions about how HIV is transmitted due to lack of knowledge, as they believed that poor nutrition and sharing facilities can transmit infection. The lack of knowledge underscores the importance of addressing sexual risk with older people. It was very clear that more needs to be done in terms of education campaigns to dispel the myths of HIV infection and to empower the elderly.

A systematic review of interventions for reducing HIV risk behaviors among people living with HIV in the United States, 1988-2012

OBJECTIVE

To conduct a systematic review to examine interventions for reducing HIV risk behaviors among people living with HIV (PLWH) in the United States.

METHODS

Systematic searches included electronic databases from 1988 to 2012, hand searches of journals, reference lists of articles, and HIV/AIDS Internet listservs. Each eligible study was evaluated against the established criteria on study design, implementation, analysis, and strength of findings to assess the risk of bias and intervention effects.

RESULTS

Forty-eight studies were evaluated. Fourteen studies (29%) with both low risk of bias and significant positive intervention effects in reducing HIV transmission risk behaviors were classified as evidence-based interventions (EBIs). Thirty-four studies were classified as non-EBIs due to high risk of bias or nonsignificant positive intervention effects. EBIs varied in delivery from brief prevention messages to intensive multisession interventions. The key components of EBIs included addressing HIV risk reduction behaviors, motivation for behavioral change, misconception about HIV, and issues related to mental health, medication adherence, and HIV transmission risk behavior.

CONCLUSION

Moving evidence-based prevention for PLWH into practice is an important step in making a greater impact on the HIV epidemic. Efficacious EBIs can serve as model programs for providers in healthcare and nonhealthcare settings looking to implement evidence-based HIV prevention. Clinics and public health agencies at the state, local, and federal levels can use the results of this review as a resource when making decisions that meet the needs of PLWH to achieve the greatest impact on the HIV epidemic.

A systematic review of HIV interventions for black men who have sex with men (MSM)

Background

Black men who have sex with men (MSM) are disproportionately burdened by HIV/AIDS. Despite this burden there has been a shortage of research on HIV interventions for black MSM. This article provides a comprehensive review of the literature on interventions for black MSM to identify effective HIV prevention intervention strategies for black MSM.

Methods

We searched 3 databases: Pubmed, Scopus, and Google Scholar to identify peer-reviewed articles and used the following search terms: African American or black; MSM or men who have sex with men and women (MSMW); HIV; program or intervention; and evaluation or intervention science or implementation research. We included research articles that assessed interventions for black men who have sex with men. We included studies that used an experimental, quasi-experimental, or pre-post test design as well as formative research studies. We also searched the CDC and NIH websites to identify planned and on-going intervention studies. We identified a total of 23 studies to include in the review.

Results

We identified 12 completed studies of interventions for black MSM. Eight of these 12 interventions aimed to reduce HIV risk behaviors and 5 found a significant reduction in HIV risk behavior over time. We identified 4 health service intervention studies for young black MSM.

Conclusions

Behavior change interventions are effective at reducing HIV risk behaviors among black MSM. However, relying only on behavioral interventions that aim to reduce HIV risk behavior will most likely not have a population-level effect on HIV infection among black MSM. There is a compelling and urgent need to develop and test comprehensive HIV testing, linkage to care, retention in care and adherence interventions for black MSM.

Meta-Analysis of Interventions for Reducing Number of Sexual Partners and Drug and Alcohol Abuse among People Living with HIV/AIDS

OBJECTIVE

To perform a systematic review and meta-analysis of the efficacy of risk reduction interventions on HIV-related risk behaviors among people living with HIV/AIDS (PLWHA).

METHODS

Studies included in the meta-analysis were randomized clinical trials (RCTs) of risk reduction interventions, which targeted PLWHA aged 18 year or older and assessed the changes of number of sexual partners, drug use, needle sharing, and/or alcohol abuse between pre- and post-intervention. The standardized mean differences (SMD) between study arms as well as between baseline and post-intervention, defined as the effect sizes (ES), were calculated in random effects models. Heterogeneity of studies was estimated by the I2 statistic.

RESULTS

Twelve RCTs involving 3993 PLWHA were included in our analysis: seven reported impacts on the number of sexual partners, and three reported impacts on drug use, needle sharing, and alcohol abuse, respectively. There were no statistically significant impacts of risk reduction interventions on the number of total sexual partners (mean ES, -0.10; 95% confidence interval [CI], -0.26, 0.06; P=0.22) or on the subset of HIV-negative or unknown-status sexual partners (mean ES, 0.003; 95% CI, -0.54, 0.54; P=0.99). Overall, risk reduction intervention studies documented a reduction of drug abuse (mean ES: -0.26; 95% CI: -0.51, -0.01; P=0.04) among HIV-infected drug users, but this impact was mainly attributable to one study. Risk reduction interventions did not show a reduction of needle sharing (mean ES, -0.15; 95% CI, -0.43, 0.13; P=0.29) or of alcohol abuse (mean ES, -0.10; 95% CI, -0.36, 0.17; P=0.47). No heterogeneity or publication bias was found across individual studies.

CONCLUSIONS

Our meta-analysis did not find a positive impacts of risk reduction interventions on number of sexual partners, drug use, needle sharing, or alcohol abuse among PLWHA, but the small number of studies meeting our review criteria limits these findings.

Risk behaviors among HIV-positive gay and bisexual men at party-oriented vacations

OBJECTIVE

This study examined substance use (intended and actual), unprotected sex, and HIV disclosure practices (disclosure and questioning) among HIV-positive men who have sex with men (MSM) at two party-oriented vacations, where substance use and sexual risk may be heightened.

METHOD

A random sample of 489 MSM attending one of two party-oriented vacations participated in PartyIntents, a short-term longitudinal survey. Nearly half (47%) completed a follow-up assessment at the event or online for up to 2 weeks after the event. We examined rates of baseline intentions to use substances, actual substance use, and unprotected intercourse among HIV-positive men in attendance.Rates among HIV-negative men were estimated for comparison. Multiple logistic regression was used to assess the impact of illegal drug use and HIV status on unprotected anal intercourse (UAI).

RESULTS

HIV-positive attendees (17%) were significantly more likely than HIV-negative attendees to use nitrite inhalants (or "poppers") (24.3% vs. 10.7%). HIV-positive attendees were also significantly more likely to have insertive UAI (64.3% vs. 34.1%) and receptive UAI (68.8% vs. 22.2%). Multivariate models showed associations between HIV status and illegal drug use with UAI (for HIV status, odds ratio [OR] = 4.5, p = .001; for any illegal drug use, OR = 16.4, p < .001). There was no evidence that the influence of drug use moderated risk by HIV status. Rates of HIV disclosure and questioning did not differ by HIV status.

CONCLUSIONS

HIV-positive men attending these events engaged in higher rates of illegal drug use and sexual risk than HIV-negative men. Prevention campaigns targeting MSM at high-risk events should include messages geared toward HIV-positive men.

Network mixing and network influences most linked to HIV infection and risk behavior in the HIV epidemic among black men who have sex with men

OBJECTIVES

We evaluated network mixing and influences by network members upon Black men who have sex with men.

METHODS

We conducted separate social and sexual network mixing analyses to determine the degree of mixing on risk behaviors (e.g., unprotected anal intercourse [UAI]). We used logistic regression to assess the association between a network "enabler" (would not disapprove of the respondent's behavior) and respondent behavior.

RESULTS

Across the sample (n = 1187) network mixing on risk behaviors was more assortative (like with like) in the sexual network (r(sex), 0.37-0.54) than in the social network (r(social), 0.21-0.24). Minimal assortativity (heterogeneous mixing) among HIV-infected men on UAI was evident. Black men who have sex with men reporting a social network enabler were more likely to practice UAI (adjusted odds ratio = 4.06; 95% confidence interval = 1.64, 10.05) a finding not observed in the sexual network (adjusted odds ratio = 1.31; 95% confidence interval = 0.44, 3.91).

CONCLUSIONS

Different mixing on risk behavior was evident with more disassortativity among social than sexual networks. Enabling effects of social network members may affect risky behavior. Attention to of high-risk populations' social networks is needed for effective and sustained HIV prevention.

Condom Use, Disclosure, and Risk for Unprotected Sex in HIV-Negative Midlife and Older Men Who Have Sex With Men

Sexual risk behaviors account for most HIV infections in men who have sex with men (MSM), and the risk of exposure from each sexual encounter increases with age. The focus of this study was to investigate which behaviors in midlife and older MSM influence their sexual risk/protection. Cross-sectional data were collected from a community-based sample of 802 MSM aged 40 years and older from community venues (e.g., bars) who completed an anonymous questionnaire. Data from a subset of 420 MSM who were HIV-negative (aged 40-81 years) were used to investigate which behaviors were associated with greater risk for unprotected anal sex. Regression analyses indicated that erection difficulties (odds ratio [OR] = 4.7; 95% confidence interval [CI] = 1.8-12.2), practicing safe sex with outside partners but not with one’s primary partner (OR = 0.54; 95% CI = 0.3-0.94), and recreational drug use (OR = 2.6; 95% CI = 1.3-5.1) were associated with higher risk for unprotected receptive anal intercourse. Younger age (OR = 0.96; 95% CI = 0.9- 0.9), not telling partners about HIV status (OR = 3.2; 95% CI = 1.5-6.5), finding partners in backrooms/sex clubs (OR = 2.8; 95% CI = 1.1- 6.8), and erection difficulties (OR = 10.3; 95% CI = 2.8-37.8) were associated with higher risk for unprotected insertive anal intercourse. These data indicate there may be certain factors specific to older MSM that influence their sexual risk taking behaviors. Programs may be more effective if they are tailored for older cohorts of MSM and address interpersonal communication, erection problems, and substance use to reduce health risks and promote healthier lifestyles.

Prevention of HIV Among Older Adults

Objective:

This study reviews the existing literature on the prevention of HIV among older adults, including universal and indicated prevention programs and prevention strategies.

Method:

A literature search was conducted between September and October of 2011 to identify studies for this review. Several different electronic databases and a combination of keywords were used to conduct the search. In addition, the reference section of each article was reviewed for additional articles.

Results:

A total of 18 articles were identified and reviewed. Three of the articles examined universal prevention, five of the articles examined indicated prevention, and the remainder of the articles provided strategies and recommendations for the prevention of HIV among older adults.

Discussion:

The existing studies document evidence for preventing future cases of HIV/AIDS among older adults. Additional studies and universal and selected interventions are needed in an effort to reduce the number of older adults being diagnosed with HIV.

Ignoring the group in group-level HIV/AIDS intervention trials: a review of reported design and analytic methods

OBJECTIVES

Studies evaluating the efficacy of HIV/AIDS interventions often involve the random assignment of groups of participants or the treatment of participants in groups. These studies require analytic methods that take within-group correlation into account. We reviewed published studies to determine the extent to which within-group correlation was dealt with properly.

DESIGN

We reviewed group-randomized trials (GRTs) and individually randomized group treatment (IRGT) trials published in HIV/AIDS and general public health journals 2005-2009.

METHODS

At least two of the authors reviewed each article, recording descriptive characteristics, sample size estimation methods, analytic methods, and judgments about whether the methods took intraclass correlation into account properly.

RESULTS

Of those articles including sufficient information to judge whether analytic methods were correct, only 24% used only appropriate methods for dealing with the intraclass correlation. The percentages differed substantially for GRTs (41.7%) and IRGT trials (8.0%). Most of the articles (69.2%) also made no mention of a priori sample size estimation.

CONCLUSION

A majority of the articles in our review reported analyses ignoring the intraclass correlation. This practice may result in underestimated variance, inappropriately small P values, and incorrect conclusions about the effectiveness of interventions. Previous trials that were analyzed incorrectly need to be re-analyzed, and future trials should be designed and analyzed with appropriate methods. Also, journal reviewers and editors need to be aware of the special requirements for design and analysis of GRTs and IRGT trials and judge the quality of articles reporting on such trials according to appropriate standards.

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.
