Minority stress and leukocyte gene expression in sexual minority men living with treated HIV infection.

ABSTRACT: Sexual minority (i.e., non-heterosexual) individuals experience poorer mental and physical health, accounted for in part by the additional burden of sexual minority stress occurring from being situated in a culture favoring heteronormativity. Informed by previous research, the purpose of this study was to identify the relationship between sexual minority stress and leukocyte gene expression related to inflammation, cancer, immune function, and cardiovascular function. Sexual minority men living with HIV who were on anti-retroviral medication, had viral load?

AWARENESS: A cognitive behavioral intervention to reduce intersectional minority stress among sexual minority men living with HIV who use substances.

Project description:IntroductionThe minority stress model is the primary explanatory model for disparities in substance use and other mental health problems among sexual minority men (SMM) compared to heterosexual men. This pilot randomized controlled trial tested the feasibility of AWARENESS, a novel 9-session cognitive-behavioral psychotherapeutic intervention that targets intersectional minority stress and stigma, among sexual minority men living with HIV who use substances.MethodsFeasibility was determined by the number of participants screened to obtain the target sample size, the percentage of eligible participants randomized, percentage of study intervention and assessment visits attended, time to complete study procedures, and percentage of data completeness of intervention assessments. Forty-two sexual minority men living with HIV with any illicit substance use or who reported at least one occasion of consuming five or more drinks in one setting in the last three months were randomized to AWARENESS (n = 22) or an attention control condition (n = 20).ResultsFeasibility of the trial was supported, with adequate completion of study procedures and visits (73% completed all intervention sessions, 71% completed all study assessment sessions). This trial also demonstrated the feasibility of using AWARENESS skills and strategies in relation to multiple intersecting identities, with participants discussing an average of 5.7 identities (e.g., sexual orientation) or individual characteristics (e.g., socioeconomic status) in relation to intervention content.ConclusionOur results support the feasibility of an AWARENESS trial to reduce intersectional minority stress related to multiple identities and characteristics among sexual minority men living with HIV who use substances.

Body image disturbance and health behaviors among sexual minority men living with HIV.

Project description:Body image disturbance is a common experience for sexual minority men living with HIV, and is associated with poor self-care behaviors. However, to date, no known cohesive theoretical model has been advanced to understand the possible antecedents and outcomes of body image disturbance in this population. Thus, the goal of the current study was to test a biopsychosocial model of body image and self-care behaviors among sexual minority men living with HIV.Participants were 106 gay and bisexual men living with HIV who completed a battery of self-report measures, including assessment of body image disturbance, depression, lipodystrophy, appearance orientation, condom use self-efficacy, antiretroviral therapy (ART) adherence, and HIV sexual transmission risk behaviors. Bayesian estimation was employed to assess model fit and direct and indirect pathways within the model.The data fit the model well, with all theorized pathways being significant. Lipodystrophy severity and appearance orientation were associated with elevated body image disturbance. In turn, body image disturbance was related to poorer ART adherence and increased HIV sexual transmission risk behaviors, through the mechanisms of elevated depressive symptoms and poor condom use self-efficacy.Elevated body image disturbance among sexual minority men living with HIV is associated with important biopsychosocial variables, which in turn are related to poorer ART adherence and increased HIV sexual transmission risk behaviors. Integrative psychosocial interventions addressing co-occurring body image disturbance, depression, and HIV self-care behaviors may be a fruitful area for future clinical practice and research.

Multiple Minority Stress and LGBT Community Resilience among Sexual Minority Men.

Project description:Minority stress theory has widespread research support in explaining health disparities experienced by sexual and gender minorities. However, less is known about how minority stress impacts multiply marginalized groups, such as lesbian, gay, bisexual, and transgender people of color (LGBT POC). Also, although research has documented resilience in the face of minority stress at the individual level, research is needed that examines macro-level processes such as community resilience (Meyer, 2015). In the current study, we integrate minority stress theory and intersectionality theory to examine multiple minority stress (i.e., racial/ethnic stigma in LGBT spaces and LGBT stigma in one's neighborhood) and community resilience (i.e., connection to LGBT community) among sexual minority men of different racial/ethnic groups who use a geosocial networking application for meeting sexual partners. Results showed that Black sexual minority men reported the highest levels of racial/ethnic stigma in LGBT spaces and White sexual minority men reported the lowest levels, with Asian and Hispanic/Latino men falling in between. Consistent with minority stress theory, racial/ethnic stigma in LGBT spaces and LGBT stigma in one's neighborhood were associated with greater stress for sexual minority men of all racial/ethnic groups. However, connection to LGBT community played more central role in mediating the relationship between stigma and stress for White than POC sexual minority men. Results suggest that minority stress and community resilience processes may differ for White and POC sexual minority men. Potential processes driving these differences and implications for minority stress theory are discussed.

Incarceration and Sexual Risk Behavior and Incident Sexually Transmitted Infection/HIV in HIV Prevention Trials Network 061: Differences by Study City and Among Black Sexual Minority Men Who Have Sex With Men, Black Sexual Minority Men Who Have Sex With Men and Women, and Black Transgender Women.

Project description:BackgroundBlack sexual minority men (BSMM) and Black transgender women face a disproportionate risk of incarceration and sexually transmitted infection (STI)/HIV, yet research on the longitudinal association between incarceration and STI/HIV risk in these groups is limited.MethodsWe used data from the HIV Prevention Trials Network (HPTN) 061 study conducted among BSMM and Black transgender women in Atlanta, Boston, Los Angeles, New York City, San Francisco, and Washington, DC, restricting analyses to those who returned for the 6-month follow-up visit when recent incarceration was measured (n = 1169). Using inverse probability of treatment weighting, we measured associations between incarceration and next 6-month multiple partnerships; selling or buying sex; condomless anal intercourse; and incident chlamydia, gonorrhea, syphilis, and HIV. We explored differences by study city, and among BSMM who had sex with men only, BSMM who had sex with men and women, and Black transgender women.ResultsApproximately 14% reported past 6-month incarceration. Incarceration was associated with next 6-month selling sex (adjusted risk ratio [ARR], 1.80; 95% confidence interval [CI], 1.12-2.87) in the overall sample and multiple partnerships among BSMM who had sex with men and women (ARR, 1.34; 95% CI, 1.10-1.63) and transgender women (ARR, 1.77; 95% CI, 1.22-2.57). There is evidence suggesting that incarceration may predict gonorrhea (ARR, 2.35; 95% CI, 0.95-5.77), with particularly strong associations observed in Los Angeles (ARR, 6.48; 95% CI, 1.48-28.38).ConclusionsIncarceration may increase STI/HIV risk among BSMM and Black transgender women. Additional mixed-methods research is needed to validate associations and understand pathways.

Project description:Although co-occurring methamphetamine (meth) use and HIV amplify the risk for neuropsychiatric comorbidities, the underlying neuroimmune mechanisms are not well characterized. We examined whether a detectable viral load and dysregulated metabolism of amino acid precursors for neurotransmitters predicted subsequent levels of sexual compulsivity and sexual sensation seeking. This 15-month longitudinal study enrolled 110 sexual minority men (SMM) living with HIV who had biologically confirmed meth use (i.e., reactive urine or hair toxicology results). Peripheral venous blood samples collected at baseline, 6 months, 12 months, and 15 months were used to measure a detectable viral load (> 40 copies/mL), the kynurenine/tryptophan (K/T) ratio, and the phenylalanine/tyrosine (P/T) ratio. The K/T and P/T ratios index dysregulated serotonin and catecholamine (e.g., dopamine) synthesis, respectively. In a cross-lagged panel model, a detectable viral load at 6 months predicted greater sexual compulsivity at 12 months after adjusting for prior levels of sexual compulsivity and recent stimulant use (β = 0.26, p = 0.046). A greater P/T ratio at baseline predicted decreased sexual sensation seeking at 6 months (β = - 0.25, p = 0.004) after adjusting for baseline sexual sensation seeking and recent stimulant use. Taken together, HIV replication and dysregulated catecholamine synthesis could potentiate sexual compulsivity while decreasing sexual pleasure in SMM who use meth.

Recent stimulant use and leukocyte gene expression in methamphetamine users with treated HIV infection.

Project description:Stimulant use may accelerate HIV disease progression through biological and behavioral pathways. However, scant research with treated HIV-positive persons has examined stimulant-associated alterations in pathophysiologic processes relevant to HIV pathogenesis. In a sample of 55 HIV-positive, methamphetamine-using sexual minority men with a viral load less than 200?copies/mL, we conducted RNA sequencing to examine patterns of leukocyte gene expression in participants who had a urine sample that was reactive for stimulants (n?=?27) as compared to those who tested non-reactive (n?=?28). Results indicated differential expression of 32 genes and perturbation of 168 pathways in recent stimulant users. We observed statistically significant differential expression of single genes previously associated with HIV latency, cell cycle regulation, and immune activation in recent stimulant users (false discovery rate p?<?0.10). Pathway analyses indicated enrichment for genes associated with inflammation, innate immune activation, neuroendocrine hormone regulation, and neurotransmitter synthesis. Recent stimulant users displayed concurrent elevations in plasma levels of tumor necrosis factor - alpha (TNF-?) but not interleukin 6 (IL-6). Further research is needed to examine the bio-behavioral mechanisms whereby stimulant use may contribute to HIV persistence and disease progression.

Intersectional Effects of Sexual Orientation Concealment, Internalized Homophobia, and Gender Expression on Sexual Identity and HIV Risk Among Sexual Minority Men of Color: A Path Analysis.

Project description:AbstractIn the United States, 13 million people identify as sexual and gender minorities. The purposes of this article were to (a) examine the associations among sexual orientation concealment and internalized homophobia with HIV knowledge, health literacy, and transactional sex through sexual identity; and (b) assess whether gender expression moderates those relationships in sexual minority men of color. A multigroup mediation path model examined the association between sexual orientation concealment and internalized homophobia on HIV knowledge, health literacy, and transactional sex through sexual identity by gender expression. Results suggest that, among those with a masculine gender expression, as sexual concealment increased, health literacy decreased. The association between sexual orientation concealment and transactional sex varied by participant's gender expression as did the association between internalized homophobia and HIV knowledge. Multiple intersecting identities, when faced with anticipated discrimination and homophobia, can negatively affect health outcomes and increase HIV risk in sexual minority men of color.

Online sex partner seeking and HIV testing frequency among young Black sexual minority men.

Project description:Dating apps are a novel means of delivering HIV prevention messages. Young black sexual minority men (YBSMM) app users are at high risk for HIV and could benefit from frequent testing. Understanding testing behaviors among YBSMM is critical to inform tailored prevention interventions. We analyzed testing behaviors of 273 YBSMM, comparing typical testing frequency between app users and non-users using odds ratios. Overall, testing rates were high. App users were more likely than non-users to test at least every 12 months. App-using YBSMM exhibit high compliance with testing guidelines, which may indicate future successful uptake of biomedical preventions, such as Pre-Exposure Prophylaxis.

Posttraumatic Stress Symptoms and Emerging Adult Sexual Minority Men: Implications for Assessment and Treatment of Childhood Sexual Abuse.

Project description:Emerging adulthood (EA) is a developmental period marked by unique challenges that affect health including burgeoning occupational, relational, and financial stability; and increased risk taking in terms of sexual behavior(s) and substance use. Data were collected from 296 HIV-uninfected sexual minority men with childhood sexual abuse (CSA) histories. We analyzed baseline assessment data from a multisite randomized controlled trial that tested the efficaciousness of an experimental psychosocial treatment and examined vulnerabilities known to be linked with CSA. Our analyses compared EA sexual minority men, aged 18-29, with older sexual minority men (OSMM) on posttraumatic stress disorder (PTSD) and other mental health and substance use outcomes. We found higher odds of PTSD, odds ratio (OR) = 0.57, 95% CI [0.33, 0.96]; panic disorder or panic disorder with agoraphobia, OR = 0.36, 95% CI [0.16, 0.85]; and cocaine use, OR = 0.50, 95% CI [0.25, 0.97], among OSMM and higher odds of alcohol intoxication, OR = 5.60, 95% CI [3.20, 9.82]; cannabis use, OR = 3.09, 95% CI [1.83, 5.21]; and non-HIV sexually transmitted infections, OR = 3.03, 95% CI [1.29, 7.13], among the EA men. These results present a complex picture of health risks among sexual minority men in general and EA sexual minority men in particular. HIV seroconversion linked health risk behaviors, among sexual minority men, may be better addressed via increased attention to treating trauma and comorbid mental health and substance use problems using evidence-based psychosocial assessments and integrated treatment platforms that are tailored to this population.
