Effectiveness of a Combined Motivational Interviewing and Cognitive Behavioral Intervention to Reduce Substance Use and Improve HIV-Related Immune Functioning.

This study evaluated the effectiveness of Project PLUS, a 6-session Motivational Interviewing and Cognitive Behavioral intervention to reduce substance use and improve antiretroviral therapy (ART) adherence among PLWH. In a quasi-experimental design, 84 participants from a network of three comprehensive care clinics in New York City received the intervention immediately post-baseline (the Immediate condition) and 90 were assigned to a Waitlist control. Viral load and CD4 data were extracted from electronic medical records (EMR) for a No-Intervention comparison cohort (n = 120). Latent growth curve analyses did not show a consistent pattern of significant between-group differences post-intervention or across time in ART adherence or substance use severity between Immediate and Waitlist participants. Additionally, Immediate intervention participants did not differ significantly from the Waitlist or No-Treatment groups on viral load or CD4 post-intervention or across time. The potential to detect intervention effects may have been limited by the use of a quasi-experimental design, the high quality of standard care at these clinics, or inadequate intervention dose.Trial Registration: ClinicalTrials.gov (NIH U.S. National Library of Medicine) Identifier: NCT02390908; https://clinicaltrials.gov/ct2/show/NCT02390908.

The importance of domain-specific self-efficacy assessment for substance use and HIV care continuum outcomes among adults in an urban HIV clinic network.

Despite the prominence of self-efficacy as a predictor of antiretroviral therapy (ART) adherence, relatively little work has examined domain-specific associations with steps in the care continuum or the possibility that substance use may have domain-specific associations with self-efficacy. This study analyzed data from a sample of 174 people living with HIV recruited through three clinics in the New York City metro area. Consistent with hypotheses, path analysis showed that appointments kept and viral load were each predicted only by their respective domain-specific self-efficacy components (i.e., self-efficacy for keeping appointments, B = 0.01, p = .04; and self-efficacy for taking ART medications, B = -0.02, p < .01). Path models also indicated domain-specific associations with substance use. Self-efficacy for keeping appointments was negatively associated with severity of drug use (B = -1.81, p < .01); meanwhile, self-efficacy for taking ART medications was negatively associated with severity of alcohol use (B = -0.52, p < .01). Accordingly, studies assessing barriers to retention in the HIV care continuum should conduct multi-domain assessments of self-efficacy for differential associations with specific behaviors. Furthermore, HIV care providers might consider screening for domain-specific self-efficacy to identify patients at risk of drop-out and tailoring interventions to various care continuum domains.

Sexual Subcultures and HIV Prevention Methods: An Assessment of Condom Use, PrEP, and TasP Among Gay, Bisexual, and Other Men Who Have Sex with Men Using a Social and Sexual Networking Smartphone Application.

Despite being grouped together in epidemiological risk categories, gay, bisexual, and other men who have sex with men (GBM) are not a homogenous group. In addition to traditional segmentation along race, ethnicity, and socioeconomic status, many GBM also identify with sexual subcultural communities. Previous research has shown differences across a variety of health outcomes between these sexual subcultural communities. The purpose of this study was to determine whether HIV prevention practices among GBM differed according to sexual subcultural community. The study was conducted in collaboration with a popular social and sexual networking smartphone application company. A total of 23,577 GBM responded to the survey. A latent class analysis identified 6 distinct classes related to sexual subcultural community identification. We found significant differences across sociodemographic characteristics, HIV prevention practices, and condomless anal sex in the past 6 months related to sexual subculture identification. Findings suggest that sexual subcultural identity is related to decision-making around HIV prevention among GBM. Differences in HIV prevention strategies are likely a function of group norms, unique shared experiences among GBM identifying with a particular sexual subculture community, and sociodemographic characteristics associated with these groups. As such, sexual subculture identity should be considered in developing interventions and social marketing campaigns to increase uptake of biomedical HIV prevention tools among GBM. Identifying group norms and shared experiences related to HIV prevention practices among sexual subcultures is necessary to understand the role these identities play in lives of GBM, especially as it relates to their sexual health and well-being.

High willingness to use novel HIV and bacterial sexually transmitted infection partner notification, testing, and treatment strategies among gay and bisexual men.

OBJECTIVES: We sought to determine willingness of gay and bisexual men (GBM) to give HIV self-testing (HIVST) kits with patient-delivered partner therapy (PDPT) and engage in geosocial sexual networking (GSN) app-based partner notification. METHODS: A nationwide sample of GBM who self-tested HIV negative (n=786) were asked about their willingness to give recent sex partners (main and casual) PDPT with an HIVST kit (PDPT+HIVST) after hypothetical bacterial STI (BSTI) diagnosis. Men were also asked about their willingness to notify sexual partners met on GSN apps using an anonymous app function after BSTI diagnosis. We examined associations of relationship status and condomless anal sex with casual partners, recent BSTI diagnosis and perceived risk of HIV on PDPT+HIVST and anonymous app-based partner notification willingness (dichotomised) using binary logistic regressions, adjusting for age, race/ethnicity, education and US region. From the partner's perspective after receiving an app-based referral, frequency measures were used to report intentions for obtaining subsequent HIV/BSTI counselling and testing, engaging in HIVST if provided a free voucher, and obtaining BSTI treatment from a pharmacy with prescription voucher. RESULTS: Most (90.1%) were willing to give PDPT+HIVST to recent sex partners after STI diagnosis, and nearly all (96.4%) were willing to notify sex partners met online using an anonymous function within GSN apps. Regardless of casual partner condomless anal sex engagement, partnered GBM had higher odds of reporting willingness to give PDPT+HIVST compared with single men who recently engaged in condomless anal sex with a casual partner. If anonymously notified via an app, 92.5% reported they would likely obtain counselling and testing, 92.8% would engage in HIVST if provided a free voucher, and 93.4% would obtain treatment from a pharmacy with prescription voucher. CONCLUSIONS: GBM generally found novel partner notification, testing, and treatment strategies acceptable, indicating the need for feasibility and cost-effectiveness evaluations.

Rates of Pre-exposure Prophylaxis Use and Discontinuation Among a Large U.S. National Sample of Sexual Minority Men and Adolescents.

Pre-exposure prophylaxis (PrEP) is highly effective in the prevention of HIV acquisition and was recently approved for those under 18 years of age. The primary goal of the present study was to understand the prevalence of and factors associated with PrEP use among a large sample of young and adult sexual minority men (Y/SMM). Participants came from a larger national sample of SMM. Data collected included demographics, substance use, PrEP use, and sexual risk. Participants were recruited via sexual networking/dating applications and resided in the U.S. including Puerto Rico, were at least 13 years old, self-reported being HIV-negative, and identified as male. The sample was divided into two groups: YSMM (13-24 years of age) and adult SMM (25 years of age and up). Multinomial logistic regressions examining associations with never, current, and former PrEP use were run with all variables of interest simultaneously entered into the models. Age was positively associated with both former and current PrEP use among YSMM. Additionally, YSMM who identified as gay (vs. bisexual), lived in the Northeast, Midwest, and West (vs. South), had their own health insurance (vs. those on their parent's), had recently been diagnosed with an STI, and had recently used a drug all had higher odds of being a current PrEP user compared to those that had never used PrEP. Among adult SMM, those who were older did not have higher odds of current PrEP use compared to those that had never used PrEP. Those who identified as queer (vs. gay), single, had their own or were on their partner's insurance (vs. parent's), recent condomless anal sex, recent STI diagnosis, recent drug use, and recent substance use all had higher odds of being a current PrEP user compared to those that had never used PrEP. Research is needed to address the disparities in PrEP uptake among YSMM. Interventions for PrEP access among those on their parents' insurance may also be necessary.

The Mediating Role of Psychological Distress in the Association between Harassment and Alcohol Use among Lesbian, Gay, and Bisexual Military Personnel.

BACKGROUND: The purpose of this study was to examine the mediating role of psychological distress on the associations between two forms of harassment, military sexual trauma (MST) and sexual orientation-based discrimination (SOBD), and alcohol use in a sample of lesbian, gay, and bisexual (LGB) military personnel. Methods: Data were analyzed from 254 LGB military service members in the United States. Bivariate associations were examined between MST, SOBD, anxiety and depression, distress in response to stressful military events, and alcohol use. A latent psychological distress factor was estimated using anxiety and depression, and distress in response to stressful military events. Path analyses were used to estimate the direct effects of MST and SOBD on alcohol use and the indirect effects of MST and SOBD on alcohol use through psychological distress. Results: All bivariate associations were positive and significant between MST, SOBD, anxiety and depression, distress in response to military events, and alcohol use. In multivariable analyses, after adjusting for demographic covariates, a significant indirect effect was observed for SOBD on alcohol use through psychological distress. MST was not directly or indirectly associated with alcohol use when SOBD was included in the path model. Conclusion: Overall, findings suggest SOBD is associated with poorer mental health, which in turn places LGB military personnel at greater risk of alcohol use and associated problems. These results affirm the need for interventions that reduce SOBD in the military and suggest that these interventions will have a positive impact on the health of LGB military personnel.

Cardiovascular and psychopathological factors among non-sexually compulsive, sexually compulsive, and hypersexual individuals in Sao Paulo, Brazil.

We decided to explore the frequency of cardiovascular risk factors, according to three levels of severity of compulsive sexual behavior (CSB), namely, non-sexually compulsive (1), sexually compulsive (2), and sexually compulsive, and hypersexual (3). We also investigated the impact of a psychiatric co-morbidity on the Framingham heart risk score (FRS). 94 non-sexually compulsive, 57 sexually compulsive, and 60 hypersexual individuals underwent psychiatric interview, blood collection, self-responsiveness, and anthropometric measurement. The analyses were repeated with individuals aged up to 44 and aged more than 44 years old. Regarding the total sample, we observed significant association among those sexually compulsive, and hypersexual participants with presenting the HIV serologic status, and a greater proportion of psychiatric conditions as much as the severity of CSB increases. Individuals with substance-related disorder predicted higher Framingham scores. The analyses with people aged more than 44 years old presented some different results, such as association among presenting low FRS and the sexually compulsive participants, and sexual compulsivity predicted lower scores of the Framingham. The study points out to the relevance of comprehensive psychiatric examination of whom presenting CSB and opens an avenue forward investigation of the effect of high rates of sexual activity on cardiovascular risk.

Club drug users had higher odds of reporting a bacterial STI compared with non-club drug users: results from a cross-sectional analysis of gay and bisexual men on HIV pre-exposure prophylaxis.

OBJECTIVES: Pre-exposure prophylaxis (PrEP) can reduce HIV transmission risk for many gay, bisexual and other men who have sex with men. However, bacterial STI (BSTI) associated with decreasing condom use among HIV PrEP users is a growing concern. Determining the characteristics of current PrEP users at highest BSTI risk fills a critical gap in the literature. METHODS: Gay and bisexual men (GBM) in New York City on HIV PrEP for 6 or more months (n=65) were asked about chlamydia, gonorrhoea and syphilis diagnoses in the past 6 months. By design, half (51%) of the sample were club drug users. We examined the associations of length of time on PrEP, type of PrEP care provider, PrEP adherence, number of sexual partners, number of condomless anal sex acts and club drug use on self-reported BSTI using multivariable, binary logistic regressions, adjusting for age, race/ethnicity, education and income. RESULTS: Twenty-six per cent of GBM on HIV PrEP reported a diagnosis of BSTI in the past 6 months. Men who reported club drug use (adjusted OR (AOR)=6.60, p<0.05) and more frequent condomless anal sex in the past 30 days (AOR=1.13, p<0.05) had higher odds of reporting a BSTI. No other variables were significantly associated with self-reported BSTI in the multivariable models. CONCLUSIONS: Club drug users could be at a unique BSTI risk, perhaps because of higher risk sexual networks. Findings should be considered preliminary, but suggest the importance of ongoing BSTI screening and risk-reduction counselling for GBM on HIV PrEP.

What's Sleep Got to Do with It?: Sleep Health and Sexual Risk-Taking Among Men Who have Sex with Men.

Emerging evidence links poor sleep health with a range of adverse health behaviors, including condomless anal intercourse (CAI) among men who have sex with men (MSM). We tested associations between a range of sleep health indicators and sex outcomes in an online sample of 559 MSM in Paris France, recruited from a geosocial-networking phone application. Participants reported on sleep quality, sleep duration, problems falling asleep, and problems staying awake during wake-time activities, and four sex outcomes: numbers of receptive, insertive, and total CAI partners in the past three months, and use of substances before or during sex. In bivariate analyses, all four sleep variables were associated with the three CAI outcomes, whereas poor sleep quality and problems falling asleep were positively associated with using substances before or during sex. Most of these associations remained significant when adjusting for various socio-demographic and behavioral covariates. These findings highlight the importance of addressing sleep health to prevent HIV risk among MSM.

Determining the Roles that Club Drugs, Marijuana, and Heavy Drinking Play in PrEP Medication Adherence Among Gay and Bisexual Men: Implications for Treatment and Research.

Researchers have established that substance use interferes with anti-retroviral medication adherence among gay and bisexual men (GBM) living with HIV. There is limited parallel examination of pre-exposure prophylaxis (PrEP) adherence among HIV-negative GBM. We conducted retrospective 30-day timeline follow-back interviews and prospective semi-weekly diary data for 10 weeks with 104 PrEP-using GBM, half of whom engaged in club drug use (ketamine, ecstasy, GHB, cocaine, or methamphetamine)-generating 9532 days of data. Participants reported their day-by-day PrEP, club drug, marijuana, and heavy alcohol use (5 + drinks in one sitting). On average, club drug users were no more likely to miss a dose of PrEP than non-club drug users (M = 1.6 doses, SD = 3.0, past 30 days). However, we found that club drug use (at the event level) increased the odds of missing a dose on the same day by 55% and the next day (e.g., a "carryover effect") by 60%. Further, missing a dose on one day increased the odds of missing a dose the following day by eightfold. We did not identify an event-level effect of marijuana use or heavy drinking on PrEP adherence. Our data suggest club drug users could have greater protective effects from daily oral or long-acting injectable PrEP compared to a time-driven PrEP regimen because of the concurrence of club drug use and PrEP non-adherence.

A Pilot Randomized Trial of Intervention Components Addressing Drug Use in Couples HIV Testing and Counseling (CHTC) with Male Couples.

Men who have sex with men (MSM) experience high rates of substance use and HIV infection. Main partners are the source of many (35-68%) of these new HIV infections. This study developed and examined the efficacy of two adjunct components to couples HIV testing and counseling (CHTC)-communication training (CT) videos and a substance use module (SUM)-to reduce drug use and sexual HIV transmission risk in MSM couples. Participants included 70 male couples randomized into one of four conditions: CHTC, CHTC + CT videos, CHTC + SUM, and CHTC + CT videos + SUM. Participants completed a survey pre-intervention and 1-, 3-, and 6-months later. Completion of the SUM in the absence of CT videos was associated with significant immediate decreases in drug use and related problems; however, at 3- and 6-month follow ups, the SUM was only associated with reductions in drug use and related problems among men who also viewed the CT videos. There were no between-condition differences in sexual behavior. CHTC may serve as a vehicle for the delivery of brief substance use intervention for MSM couples.ClinicalTrails.gov NCT # 03125915.

Evaluation of Sex Positive! A Video eHealth Intervention for Men Living with HIV.

Sex Positive![+] is a two-arm, video-based web intervention aimed at reducing condomless anal sex (CAS) with partners of known and unknown serostatus that was delivered online to a racially and ethnically diverse sample of 830 gay, bisexual, and other men who have sex with men living with HIV. Men in each arm received 6 weekly videos after completing a baseline assessment and 4 weekly booster videos following a 6-month assessment. Follow-up assessments were conducted every 3 months for 1 year. At 3-month follow-up, men in the intervention arm reported significantly reduced risk of having unknown serodiscordant CAS partners than men in the control arm (RR 0.60, 95% CI 0.39-0.92), partially supporting study hypotheses. Aside from this finding, similar reductions in sexual risk behaviors were observed in both arms over the study period. There is much to be learned about video-based web interventions in terms of methodological development and intervention delivery, including frequency and duration of intervention components.

Three Reasons to Consider the Role of Tiredness in Sexual Risk-Taking Among Gay and Bisexual Men.

Numerous factors have been shown to increase sexual risk-taking-especially among gay and bisexual men (GBM), who remain disproportionately affected by HIV and STIs. We present three lines of evidence that highlight the need to consider a previously under-explored situational factor in sexual risk-taking: tiredness. While tiredness has been shown, in sleep science literature, to impair cognition, emotional functioning, and decision-making in a wide range of behaviors, it has yet to be considered in-depth as a risk factor in sexual behavior. Counter to the common-sense assumption that being tired should impede the performance of active, effortful behaviors such as sex, we propose that tiredness may actually increase sexual risk-taking. Analyzing data from an online survey of 1113 HIV-negative GBM, we found that sex with casual partners most commonly occurred at night, especially among younger GBM and those with an evening chronotype, and that sex without condoms more often occurred at or later than one's usual time of feeling tired (as was reported by 44.2% of men) than did sex with condoms (reported by 36.6%). We also found that tiredness can increase sexual desire in many GBM (endorsed by 29.9%), and increases the likelihood of engaging in receptive positioning in anal sex (endorsed by almost 40% of men with a versatile sexual positioning identity). These findings highlight the importance of considering tiredness as a situational risk factor in sexual health-especially among younger GBM-and of counting sex among the behaviors that can be adversely impacted by poor or overdue sleep.

The Prevalence and Correlates of Sexual Arrangements in a National Cohort of HIV-Negative Gay and Bisexual Men in the United States.

Sexual agreements have received considerable attention as an aspect of dyadic functioning associated with HIV risk. To date, this research has primarily utilized convenience samples which overrepresented men from large urban areas and with higher HIV risk. The current study utilized a national cohort of 1061 HIV-negative gay and bisexual men recruited to be geographically diverse within the U.S. The sample included 531 (50.0%) men who identified as single. Of the 530 partnered men, 240 (45.3%) were monogamous; 238 (44.9%) were in open relationships (where sex with outside partners was permitted); and 52 (9.8%) were in monogamish relationships (where sex with outside partners was limited to instances where both primary partners were present). Regardless of urban (vs. non-urban) residence, men in monogamous relationships engaged in less anal sex generally and condomless anal sex (CAS) specifically with casual partners. Single men reported significantly more frequent anal sex with casual partners compared to open and monogamish men; however, there were no significant differences among these three groups with respect to CAS with casual partners. In multivariable models, monogamish men reported significantly more frequent marijuana use and alcohol consumption compared to all other groups. Urban (vs. non-urban) residence moderated associations between sexual arrangements and depression as well as the use of illicit drugs other than marijuana. These findings point to the need to better examine the potentially unique mechanisms which confer risk and resilience for gay male couples in urban versus non-urban settings. The observed association between sexual arrangements and substance use suggests interventions which facilitate the negotiation of sexual agreements may present an opportunity to engage in dyadic substance use intervention.

An Examination of Gay Couples' Motivations to Use (or Forego) Pre-exposure Prophylaxis Expressed During Couples HIV Testing and Counseling (CHTC) Sessions.

While many gay couples perceive themselves to have little risk for HIV transmission, research estimates that 35-68% of new HIV infections are transmitted within main partnerships. Pre-exposure prophylaxis (PrEP) is recommended for those partnered gay and bisexual men (GBM) who engage in sex outside their primary relationship or who have an HIV-positive partner. There is reason to believe that couples' sero-status and sexual agreement will shape perceptions of PrEP's personal relevance among gay couples. The current study examined motivations for and ambivalence towards PrEP uptake reported in a sample of 67 gay couples during completion of a brief CDC-recommended prevention intervention: Couples HIV Testing and Counseling. Findings suggest that all types of couples identified some circumstances in which they would consider PrEP; however, PrEP messaging should be crafted to avoid undermining current prevention strategies or threatening the trust and legitimacy of the relationship.

Gay and Bisexual Men's Strategies to Maintain Daily Adherence to Their HIV Pre-exposure Prophylaxis (PrEP) Medication: Results from a Qualitative Study.

Since FDA approval in 2012, HIV pre-exposure prophylaxis (PrEP) has been adopted by key populations, including gay and bisexual men (GBM), to reduce their HIV transmission risk. Given that PrEP is optimally effective when taken as prescribed, it is critical to understand the adherence strategies GBM use. We conducted one-on-one, semi-structured interviews with GBM taking PrEP in 2015-2016 (n = 103). Using thematic analysis, we identified six adherence strategies, with most participants (84.3%) utilizing multiple strategies to maintain adequate adherence: (1) integrating PrEP into part of a daily routine, (2) using a pillbox, (3) cognitive strategies/visual cues, (4) setting recurring smartphone alarms or reminders, (5) keeping medication on oneself at all times, and (6) partner or peer support for reminders and/or pill sharing. Overall, participants reported high PrEP adherence (M = 1.6 missed doses in the prior 30 days), though nearly all described missing at least one dose unintentionally in the past. Participants credited their high levels of adherence in part to the strategies they adopted. Providers working with GBM prescribed PrEP, especially patients reporting difficulties with adherence, might consider recommending any or all of the six strategies described in this study.

Human Immunodeficiency Virus/Sexually Transmitted Infection Counseling and Testing Services Received by Gay and Bisexual Men Using Preexposure Prophylaxis at Their Last PrEP Care Visit.

BACKGROUND: Preexposure prophylaxis (PrEP) reduces risk of human immunodeficiency virus infection for many gay and bisexual men (GBM); however, bacterial sexually transmitted infections associated with decreasing condom use among users is of concern. Center for Disease Control and Prevention's guidelines for PrEP use recommend bacterial sexually transmitted infection screening every 6 months. We sought to investigate comprehensive PrEP care, defined as: (1) discussion of sexual behavior, (2) blood sample, (3) urine sample, (4) rectal sample (rectal swab), and (5) throat sample (throat swab), provided at the user's last PrEP appointment. METHODS: The PrEP-using GBM in New York City (n = 104) were asked about their last PrEP care visit. We examined associations of demographics (age, race/ethnicity, and education), recent number of condomless anal sex events, time on PrEP, and health care provider type on receiving comprehensive care at last visit using fully adjusted binary logistic regression. RESULTS: At their last visit, nearly all men (94%) gave blood for testing, 88% provided a urine sample, and 77% discussed sexual behavior with their provider. However, only 51% reported having a rectal swab, and 48% an oral swab. Only 32% of men received comprehensive PrEP care at their last PrEP visit. Odds of receiving comprehensive care were significantly higher among younger men, men with a bachelor's degree or more education, and those who reported more condomless anal sex. CONCLUSIONS: Less than one third of GBM received comprehensive human immunodeficiency virus/sexually transmitted infection counseling and testing at their last visit. These findings indicate further efforts are needed to prepare health care providers for prescribing and managing patients on PrEP.

HIV Preexposure Prophylaxis Initiation at a Large Community Clinic: Differences Between Eligibility, Awareness, and Uptake.

OBJECTIVES: To characterize uptake of HIV preexposure prophylaxis (PrEP) in a community setting and to identify disparities in PrEP use by demographic and behavioral factors associated with increased HIV risk. METHODS: We conducted a cross-sectional study of 19 587 men who have sex with men and transgender people visiting a Los Angeles, California, clinic specializing in lesbian, gay, bisexual, and transgender care between August 2015 and February 2018 by using clinical care data. RESULTS: Seventy percent of patients met PrEP eligibility criteria, while 10% reported PrEP use. Using sex drugs, reporting both condomless anal intercourse and recent sexually transmitted infection, older age, and higher education level were associated with higher odds of PrEP use given eligibility. Latino or Asian race/ethnicity and bisexual orientation were associated with lower odds of PrEP use given eligibility. Higher odds of perceived need were associated with demographic risk factors but PrEP use was not similarly elevated. CONCLUSIONS: Discrepancies between PrEP eligibility, perceived need, and use reveal opportunities to improve PrEP delivery in community settings. Public Health Implications. Efforts are needed to facilitate PrEP uptake in populations with highest HIV incidence.

The Somatic Marker Hypothesis and Sexual Decision Making: Understanding the Role of Iowa Gambling Task Performance and Daily Sexual Arousal on the Sexual Behavior of Gay and Bisexual Men.

Background: The sexual decision-making literature suggests that sexual arousal and behavior are associated. The somatic marker hypothesis suggests that individual neuropsychological differences in decision making, as measured by the Iowa Gambling Task (IGT), may moderate these associations; however, this hypothesis has yet to be tested with event-level sexual behavior data. Purpose: We hypothesized that (a) daily sexual arousal would be positively associated with likelihood of engaging in sex and condomless anal sex (CAS) and (b) IGT scores would moderate these associations such that the associations would be stronger among those with higher IGT scores. Methods: We used daily diary data from 334 highly sexually active gay and bisexual men to examine the main and interaction effects of sexual arousal and IGT scores on sexual engagement and CAS. Results: As hypothesized, daily sexual arousal was positively associated with greater odds of both sexual engagement and CAS with casual male partners. Individual-level IGT performance significantly moderated the day-level association between arousal and sexual engagement, which was stronger for men with higher IGT scores. There was no main effect of IGT scores on either sexual behavior outcome, nor did it moderate the association between arousal and CAS. Conclusions: These findings highlight the influence of sexual arousal on sexual engagement, which differed by IGT scores; the effect of arousal on CAS was much less variable and may not be moderated by neurocognitive factors. This study supports the importance of exploring integrated behavioral/biomedical interventions to improve individual decision making to prevent HIV infection.

Drug Use and HIV Prevention With Young Gay and Bisexual Men: Partnered Status Predicts Intervention Response.

The Young Men's Health Project (YMHP) has shown efficacy in reducing drug use and condomless anal sex (CAS) with casual partners among young gay, bisexual and other men who have sex with men (YGBMSM). The study examined whether relationship status at the time of intervention predicted response to YMHP by comparing baseline (pre-intervention) and follow-up (3, 6, 9, and 12 months post-intervention) data from the original trial. A group of 13 partnered YGBMSM who received YMHP was compared to a matched subsample of single YGBMSM. Among single men, drug use declined significantly at all follow-ups. Among partnered men, drug use was largely stable. While significant reductions were observed at 9 month assessment, 3, 6, and 12 month use did not differ significantly from baseline. Regardless of relationship status, CAS with casual partners declined significantly at 12 month follow-up. Results suggest the incorporation of components which address relationship factors, particularly those associated with drug use, may enhance benefits of YMHP for partnered YGBMSM.
