Sexual behavior and HIV risk among age-discrepant, same-sex male couples

Abstract Research has suggested that men who have sex with men and who have older sexual partners are at increased risk of HIV infection. However, while several studies have explored risk among men in age-discrepant non-primary partnerships, only two have explored age discrepancy and risk in primary same-sex male relationships. We used data from semi-structured in-depth interviews to explore sexual behaviour and HIV risk among 14 Black, white and interracial (Black/white) same-sex male couples with an age difference of 10 or more years. Most couples regularly used condoms, and sexual positioning tended to lead to lower risk for younger partners. Some serodiscordant couples abstained from anal sex, while others used seropositioning to avoid transmission within the relationship. Within some couples, older partners acted as mentors on HIV prevention and broader life lessons. Future studies should further explore the potential risks and benefits of large age differences in same-sex male primary relationships.

Relationship Power Among Same-Sex Male Couples in New York and San Francisco: Laying the Groundwork for Sexual Risk Reduction Interventions Focused on Interpersonal Power

Research is clear that power differentials between women and men shape women’s human immunodeficiency virus (HIV) risks; however, little research has attempted to examine power differentials within same-sex male (SSM) couples and whether these influence sexual risk outcomes. To produce the first quantitative scale that measures power in SSM relationships, the current work was a Phase 1 qualitative study that sought to understand domains of relationship power and how power operated in the relationship among 48 Black, White, and interracial (Black–White) SSM couples recruited from San Francisco and New York. Interview domains were focused on definitions of power and perceptions of how power operated in the relationship. Findings revealed that couples described power in three key ways: as power exerted over a partner through decision-making dominance and relationship control; as power to accomplish goals through personal agency; and as couple-level power. In addition, men described ways that decision-making dominance and relationship control could be enacted in the relationship—through structural resources, emotional and sexual influence, and gender norm expectations. We discuss the implications of these findings for sexual risks and HIV care and treatment with SSM couples that are focused on closing gaps in power.

A Conceptual Model of Dyadic Coordination in HIV Care Engagement Among Couples of Black Men Who Have Sex with Men: A Qualitative Dyadic Analysis

Among Black men who have sex with men (MSM), HIV incidence is disproportionately high and HIV care engagement is disproportionately low. There may be important opportunities to leverage the primary relationship to improve engagement in HIV care and treatment among Black MSM couples. Using dyadic qualitative analysis of semi-structured, one-on-one interviews, we explored dyadic aspects of HIV care engagement among 14 Black MSM couples in which at least one partner was HIV-positive and identified as a Black cisgender man. Findings showed that men varied in how involved they were in their HIV-positive partner’s care and treatment, and in how they reciprocated their partner’s involvement. Patterns of dyadic HIV care engagement supported a conceptual model of dyadic coordination that describes Black MSM relationships in terms of two conceptual dimensions of dyadic HIV care engagement, and guides future intervention designs with Black MSM couples.

African-American and Hispanic Perceptions of HIV Vaccine Clinical Research: A Qualitative Study:

Purpose. To examine perceptions of phase-I human immunodeficiency virus (HIV) vaccine trial participation among African-Americans and Hispanics in San Francisco, California. Design. Qualitative, semistructured interviews. Setting. San Francisco Department of Health. Participants. Thirty-six African-American and Hispanic men and women, 18 to 50 years of age, residing in the San Francisco Bay Area. Method. Purposive sampling using advertisements, community-based organization rosters, and snowball referrals. Thematic analysis of transcripts identified salient themes and patterns. Results. Participants viewed participation in HIV research as important; however, they held that HIV was not a health priority given limited awareness about HIV research or beliefs that only infected or high-risk persons were eligible for participation. Altruism and personal gain, trustworthy trial staff, convenient schedules and facilities, and involvement of trusted community groups in recruitment were perceived to motivate participants. Concerns about the social consequences of participating in HIV research and product-related side effects were seen as discouraging participation. Limitations include the possibility that participants in interview research have more favorable views of biomedical research than those who refuse to participate. Conclusion. Historically, African-Americans and Hispanics in the United States have had limited participation in HIV trials. Understanding their perceptions of HIV biomedical research, identifying facilitators and barriers to participation, addressing misinformation about HIV, distorted risk perceptions, HIV stigma, and providing accessible opportunities to participate are imperative to ensure health equity and generalizability of findings.

Development and Validation of the Power Imbalance in Couples Scale

Few researchers have quantitatively explored the relationship power-HIV risk nexus in same-sex male couples. We developed and validated the Power Imbalance in Couples Scale (PICS) to measure relationship power among men in same-sex, committed relationships and its association with sexual risk behaviors. We recruited three independent and diverse samples of male couples in the greater San Francisco and New York City metropolitan areas and conducted qualitative interviews (N1 = 96) to inform item development, followed by two quantitative surveys (N2 = 341; N3 = 434) to assess the construct, predictive, convergent, and discriminant validity of the PICS. Exploratory factor analysis of the first survey’s data yielded four factors—overtly controlling partner, supportive partner, conflict avoidant actor, and overtly controlling actor—that accounted for more than 50% of the shared variance among the PICS items. Confirmatory factor analysis (CFA) of the second survey’s data supported these four factors: χ2(1823) = 2493.40, p < .001; CFI = .96, RMSEA = .03 and WRMR = 1.33. Strong interfactor correlations suggested the presence of a higher-order general perception of power imbalance factor; a higher-order factor CFA model was comparable in fit to the correlated lower-order factors’ CFA: χ2(2) = 2.00, p = .37. Internal reliability of the PICS scale was strong: α = .94. Men perceiving greater power imbalances in their relationships had higher odds of engaging in condomless anal intercourse with outside partners of discordant or unknown HIV status (OR 1.27; 95% CI 1.01–1.60; p = .04). The PICS is an important contribution to measuring relationship power imbalance and its sequelae among male couples; it is applicable to research on relationships, sexuality, couples, and HIV prevention.

Beyond Social Desirability Bias: Investigating Inconsistencies in Self-Reported HIV Testing and Treatment Behaviors Among HIV-Positive Adults in North West Province, South Africa

This mixed-methods study used qualitative interviews to explore discrepancies between self-reported HIV care and treatment-related behaviors and the presence of antiretroviral medications (ARVs) in a population-based survey in South Africa. ARV analytes were identified among 18% of those reporting HIV-negative status and 18% of those reporting not being on ART. Among participants reporting diagnosis over a year prior, 19% reported multiple HIV tests in the past year. Qualitative results indicated that participant misunderstandings about their care and treatment played a substantial role in reporting inaccuracies. Participants conflated the term HIV test with CD4 and viral load testing, and confusion with terminology was compounded by recall difficulties. Data entry errors likely also played a role. Frequent discrepancies between biomarkers and self-reported data were more likely due to poor understanding of care and treatment and biomedical terminology than intentional misreporting. Results indicate a need for improving patient-provider communication, in addition to incorporating objective measures of treatment and care behaviors such as ARV analytes, to reduce inaccuracies.
