RESUMO
Unhealthy alcohol use, which encompasses heavy episodic drinking to alcohol use disorder, has been identified as a modifiable barrier to optimal HIV care continuum outcomes. Despite the demonstrated efficacy of couples-based interventions for addressing unhealthy alcohol use, there are no existing couples-based alcohol interventions designed specifically for people living with HIV. This study presents the development and refinement of a three-session couples-based motivational intervention (ReACH2Gether) to address unhealthy alcohol use among a sample of 17 sexual minority men living with HIV and their partners living in the United States. To increase potential population reach, the intervention was delivered entirely remotely. Throughout an original and a modified version, results indicated that the ReACH2Gether intervention was acceptable and there were no reports of intimate partner violence or adverse events. Session engagement and retention were high. In pre-post-test analyses, the ReACH2Gether intervention showed trends in reducing Alcohol Use Disorder Identification Test scores and increasing relationship-promoting dynamics, such as positive support behaviors and goal congruence around alcohol use. Results support the need for continued work to evaluate the ReACH2Gether intervention.
RESUMEN: El consumo no saludable de alcohol, que abarca episodios intensos de consumo hasta llegar a causar trastornos de alcohol, se ha identificado como una barrera modificable para los resultados óptimos continuos de la atención del VIH. A pesar de la eficacia demostrada de las intervenciones basadas en parejas para abordar el consumo no saludable de alcohol, no existen intervenciones de alcohol basadas en parejas diseñadas específicamente para personas que viven con el VIH. Este estudio presenta el desarrollo y perfeccionamiento de una intervención motivacional basada en parejas de tres sesiones (ReACH2Gether) para abordar el consumo no saludable de alcohol entre una muestra de 17 hombres de minorías sexuales que viven con el VIH y sus parejas que viven en los Estados Unidos. Para aumentar el alcance de la población potencial, la intervención se realizó de forma totalmente remota. A lo largo de una versión original y modificada, los resultados indicaron que la intervención ReACH2Gether era aceptable y no hubo informes de violencia de pareja o eventos adversos. El compromiso y la retención de la sesión fueron altos. En los análisis previos y posteriores a la prueba, la intervención ReACH2Gether mostró tendencias en la reducción de las puntuaciones de la prueba de identificación del trastorno por consumo de alcohol y en el aumento de las dinámicas que promueven las relaciones, como comportamientos de apoya positivas y congruencia de objetivos en torno al consumo alcohol. Los resultados respaldan la necesidad de un trabajo continuo para evaluar la intervención ReACH2Gether.

The prevalence of alcohol misuse is high among people with HIV (PWH); however, access to and utilization of evidence-based alcohol misuse interventions remain limited. Telehealth is one treatment approach with the potential for enhancing substance use disorder treatment utilization for PWH served by Federally Qualified Health Centers (FQHCs). However, questions remain regarding barriers to alcohol-focused telehealth service integration and telehealth research in FQHCs. This study employed qualitative methods, guided by the Dynamic Sustainability Framework, to evaluate barriers and cultural factors impacting FQHC telehealth integration. Eighteen qualitative interviews were completed with staff and leaders across four FQHCs. Interviews were analyzed using directed content analysis, and codes were organized into a priori and emergent themes. Key themes included the presence of common workflows for referring clients to substance use disorder treatment; existing research workflows and preferences for active project staff involvement; telehealth barriers including exacerbation of healthcare disparities and high provider turnover; and the importance of cultural humility and telehealth adaptations for sexual, gender, racial and ethnic minority clients. Findings from this study will inform the development of an alcohol-focused telehealth implementation strategy for a Hybrid Type 1 implementation effectiveness trial to enhance FQHC substance use disorder treatment.Trial registration: ClinicalTrials.gov identifier: NCT02563574..

Prior research has attributed mental health disparities between marginalized and non-marginalized populations to socioeconomic differences (i.e., education, income, employment), stigma (e.g., HIV-related discrimination), and cognitive appraisal (i.e., optimism, hostility, satisfaction with life), but the relations among these variables have not been examined concomitantly. The current study utilized structural equation modeling to examine how race and socioeconomic status impact mental health outcomes through increased exposure to stigma and more negative cognitive appraisals. Data came from a randomized controlled trial of motivational interviewing to address heavy drinking in cisgender men with HIV who have sex with men (n = 180). We found that self-reported discrimination experiences related to race/ethnicity, sexual orientation, and HIV status significantly mediated the relation between socioeconomic status and mental health concerns, whereas cognitive appraisal did not. These findings suggest that, among heavy drinking men with HIV who have sex with men, having low socioeconomic resources may increase exposure to discrimination which, in turn, may worsen mental health. Interventions that address social determinants, like socioeconomic disadvantage, and that enhance coping resources related to stigma, may have positive effects on mental health.ClinicalTrials.gov Identifier NCT01328743.

RESUMEN: Investigaciones anteriores han atribuido las disparidades de salud mental entre poblaciones marginadas y no marginadas a diferencias socioeconómicas (es decir, educación, ingresos, empleo), estigma (por ejemplo, discriminación relacionada con el VIH) y evaluación cognitiva (es decir, optimismo, hostilidad, satisfacción con la vida), pero las relaciones entre estas variables no han sido examinadas concomitantemente. El estudio actual utilizó modelos de ecuaciones estructurales para examinar cómo la raza y el estatus socioeconómico afectan los resultados de salud mental a través de una mayor exposición al estigma y evaluaciones cognitivas más negativas. Los datos provienen de un ensayo controlado aleatorio de entrevistas motivacionales para abordar el consumo excesivo de alcohol en hombres cisgénero con VIH que tienen sexo con hombres (n = 180). Encontramos que las experiencias de discriminación autoinformadas relacionadas con la raza/etnicidad, la orientación sexual y el estado serológico respecto al VIH mediaron significativamente en la relación entre el estado socioeconómico y los problemas de salud mental, mientras que la evaluación cognitiva no lo hizo. Estos hallazgos sugieren que, entre los hombres con VIH que beben mucho y tienen sexo con hombres, tener bajos recursos socioeconómicos puede aumentar la exposición a la discriminación que, a su vez, puede empeorar la salud mental. Las intervenciones que abordan los determinantes sociales, como la desventaja socioeconómica, y que mejoran los recursos de afrontamiento relacionados con el estigma, pueden tener efectos positivos en la salud mental.

The present study was designed to take an inductive, qualitative approach to understanding how discussion of alcohol-related consequences during brief motivational interventions (BMI) relate to readiness to change (RTC) prior to versus at the end of a session. Participants were thirty-four adults (35% female) recruited from the emergency room and enrolled in a randomized clinical trial of a BMI for risky alcohol use and risky sex. Seventeen participants both began and remained low on RTC over the course of the session. We selected 17 additional participants, matched on demographics, but who increased RTC over the session. Transcripts were qualitatively coded and analyzed separately within groups. Among participants who increased their RTC relative to participants who remained low on RTC by BMI end, evaluation of alcohol consequences as negative was more typical. In both groups, several consequences were neutrally evaluated. Many who remained low on RTC attributed consequences to something other than alcohol and/or minimized consequence severity. Study findings highlight the value for clinicians in eliciting and maximizing the importance of subjectively negative recent consequences to perhaps increase heavy drinkers' readiness to decrease heavy alcohol use.
RESUMO
Heavy drinking and HIV infection are independently associated with damage to the brain's white matter. The purpose of the current study was to investigate whether current alcohol consumption, HIV infection, and associated characteristics were associated with indices of white matter microstructural integrity in people living with HIV (PLWH) and seronegative individuals. PLWH and controls were categorized as non-drinkers, moderate drinkers, or heavy drinkers. White matter fractional anisotropy (FA), radial diffusivity (RD), and axial diffusivity (AD) were assessed using diffusion tensor imaging (DTI). Voxelwise analyses using tract-based spatial statistics were followed by confirmatory region-of-interest (ROI) analyses. Data from 108 participants (62 PLWH, 46 controls) were suitable for analysis. Average age (± standard deviation) was 45.2 ± 11.1 years, and the sample was 42% female. The majority of PLWH were on antiretroviral therapy (94%) and were virally suppressed (69%). PLWH and controls did not differ on substance use. Heavier alcohol intake was significantly associated with lower FA and higher RD in widespread areas. Heavy drinking was significantly associated with higher AD in a small region. The main effect of HIV was not significant, but a significant HIV-age interaction was observed. Follow-up ROI analyses confirmed the main effect of drinking group and HIV-age interaction. In conclusion, results are consistent with a dose-dependent association of alcohol use with lower white matter microstructural coherence. Concordance between FA and RD findings suggests dysmyelination as a mechanism. Findings underscore the need to address unhealthy alcohol use in HIV-positive and seronegative individuals, the consequences of which may be exacerbated by aging.

Cigarette smoking remains the leading behavioral risk factor for chronic disease and premature mortality. This RCT tested the efficacy of moderate intensity aerobic exercise as an adjunctive smoking cessation treatment among women. Participants (N = 105; age = 42.5, SD = 11.2) received brief smoking cessation counseling and 10 weeks of nicotine replacement therapy and were randomized to 12 weeks of moderate intensity exercise (Exercise; n = 53) or 12 weeks of health education (Control; n = 52). Longitudinal models, with Generalized Estimating Equations, showed no differences between Exercise and Control in cotinine-verified 7-day point prevalence abstinence (Wald = 1.96, p = 0.10) or continuous abstinence (Wald = 1.45, p = 0.23) at 12-weeks (post-treatment) or 6-, 9-, or 12-month follow-up, controlling for differences in baseline nicotine dependence. There was no effect of exercise on smoking cessation. The present study adds to the literature suggesting null effects of exercise as a smoking cessation adjunctive treatment despite promising findings in short-term laboratory based studies.

In the United States, men who have sex with men (MSM) continue to be at high-risk for HIV and other STIs, and condoms represent the most popular, affordable, and accessible method of prevention. Although a vast body of research has explored various factors associated with condom use in MSM, fewer studies have explored situation-level characteristics that affect their decisions about sex partners and condom use. Daily diary studies are well-suited to help improve our understanding of these event-level factors in detail, including the sex events themselves, partner characteristics, and motivations. As part of a larger study using ecological momentary assessment methods, high-risk MSM completed daily diary surveys about their sexual behavior on their smartphones each day for 30 days. This study explored detailed descriptive characteristics of sex events, partner characteristics, and motivations for sex and condom use, and examined whether specific aspects of these characteristics were associated with having condomless anal sex (CAS) with high-risk partners. High-risk CAS was common among MSM, with the majority of participants having met their partners online and many reporting sex the same day they met. Results showed that the odds of CAS were not higher with partners met online versus those met in other ways, but MSM were more likely to have asked online partners about their HIV status and testing history before sex. The odds of engaging in high-risk CAS was higher when MSM reported intimacy or self-assurance motives. Not having condoms readily available was a CAS motivation reported more commonly when MSM had sex with high-risk partners. Findings suggest that interventions should incorporate strategies that help MSM be safer specifically when meeting partners online and when having sex for intimacy or re-assurance. Interventions that remind MSM to carry condoms at opportune moments may also help reduce some HIV risk.

Prior research on alcohol and the immune system has tended to focus on binge doses or chronic heavy drinking. The aim of this single-session preliminary study was to characterize immune response to moderate alcohol (0.60 g alcohol per kilogram body weight) in healthy, nonchronic drinkers. The sample (N = 11) averaged 26.6 years of age and was balanced in gender. Plasma samples were collected at baseline and 1, 2 and 3 hours postconsumption. Markers of microbial translocation [lipopolysaccharide (LPS)] and innate immune response [LPS-binding protein (LBP), soluble cluster of differentiation 14 (sCD14), and selected cytokines] were measured using immunoassays. Participants completed self-report questionnaires on subjective alcohol response and craving. Linear mixed models were used to assess changes in biomarkers and self-report measures. Breath alcohol concentration peaked at 0.069 ± 0.008% 1 hour postconsumption. LPS showed a significant linear decrease. LBP and sCD14 showed significant, nonlinear (U-shaped) trajectories wherein levels decreased at 1 hour then rebounded by 3 hours. Of nine cytokines tested, only MCP-1 and IL-8 were detectable in ≥50% of samples. IL-8 did not change significantly. MCP-1 showed a significant linear decrease and also accounted for significant variance in alcohol craving, with higher levels associated with stronger craving. Results offer novel evidence on acute immune response to moderate alcohol. Changes in LBP and sCD14, relative to LPS, may reflect their role in LPS clearance. Results also support further investigation into the role of MCP-1 in alcohol craving. Limitations include small sample size and lack of a placebo condition.

BACKGROUND: Human immunodeficiency virus (HIV) infection and heavy drinking independently promote microbial translocation and inflammation. However, it is not known how alcohol use may affect these processes in people living with HIV (PLWH). This study tested the hypothesis that alcohol exacerbates innate immune dysfunction in PLWH. METHODS: Participants were 75 PLWH and 34 uninfected controls. Groups were recruited to have similar proportions of nondrinkers, moderate drinkers, and heavy drinkers. Substance use data and plasma samples were collected at up to 3 visits over a 5-year study period. Recent alcohol use was assessed with the Timeline Followback Interview. Biomarkers of microbial translocation (lipopolysaccharide, LPS) and immune activation (lipopolysaccharide binding protein, LBP; soluble CD14, sCD14; soluble CD163, sCD163) were quantified using enzyme-linked immunosorbent assays. Analyses tested 2 hypotheses: (i) that biomarker levels would be significantly higher in PLWH than controls with comparable alcohol use and (ii) that current alcohol use would exacerbate biomarker elevations in PLWH. The second analysis included the interaction of alcohol use with hepatitis C virus (HCV) coinfection. RESULTS: Groups were matched on alcohol use, smoking, and other drug use. All biomarkers were significantly higher in PLWH relative to controls (LBP: p = 0.005; LPS: p = 0.014; sCD14: p < 0.001; sCD163: p < 0.001). In PLWH, alcohol use showed a significant, positive association with sCD163, but not with other biomarkers. However, the interaction of alcohol use with HCV coinfection was significant for all biomarkers (LBP: p = 0.002; LPS: p = 0.026; sCD14: p = 0.0004; sCD163: p = 0.001). In pairwise tests with sequential Bonferroni correction, HIV/HCV coinfected individuals who drank heavily had significantly higher sCD163 compared to coinfected nondrinkers and to HIV monoinfected nondrinkers, moderate drinkers, and heavy drinkers (ps < 0.005). Coinfected moderate drinkers had significantly higher sCD163 than each monoinfected group (ps < 0.003). In addition, sCD14 was significantly higher in coinfected moderate drinkers than coinfected nondrinkers (p = 0.027). CONCLUSIONS: As predicted, PLWH had higher levels of LBP, LPS, sCD14, and sCD163 than uninfected individuals with similar alcohol use. In PLWH, alcohol by itself was significantly associated only with higher sCD163. However, heavy or moderate alcohol use was associated with elevations in macrophage activation (sCD163) and monocyte activation (sCD14) in HIV/HCV coinfected individuals.

BACKGROUND: Geofencing offers new opportunities to study how specific environments affect alcohol use and related behavior. In this study, we examined the feasibility of using geofencing to examine social/environmental factors related to alcohol use and sexual perceptions in a sample of gay and bisexual men (GBM) who engage in heavy drinking and high-risk sex. METHODS: HIV-negative GBM (N = 76) completed ecological momentary assessments for 30 days via a smartphone application and were prompted to complete surveys when inside general geofences set around popular bars and clubs. A subset (N = 45) were also asked to complete surveys when inside personal geofences, which participants set themselves by identifying locations where they typically drank heavily. RESULTS: Approximately 49% of participants received a survey prompted by a general geofence. Among those who identified at least 1 personal drinking location, 62.2% received a personal geofence-prompted survey. Of the 175 total location-based surveys, 40.2% occurred when participants were not at the location that was intended to be captured. Participants reported being most able to openly express themselves at gay bars/clubs and private residences, but these locations were also more "sexualized" than general bars/clubs. Participants did not drink more heavily at gay bars/clubs, but did when in locations with more intoxicated patrons or guests. CONCLUSIONS: Geofencing has the potential to improve the validity of studies exploring environmental influences on drinking. However, the high number of "false-positive" prompts we observed suggests that geofences should be used carefully until improvements in precision are more widely available.

BACKGROUND: There is growing concern about the health impact of heavy alcohol use in people infected with human immunodeficiency virus (HIV+). Mixed findings of past studies regarding the cognitive impact of alcohol use in HIV+ adults have been mixed, with inconsistent evidence that alcohol consumption exacerbates HIV-associated brain dysfunction. This study examined contributions of current heavy drinking, lifetime alcohol use disorder (AUD), and age to cognitive deficits in HIV+ adults, and relative to other HIV-associated clinical factors. METHODS: Cognitive performance of HIV+ adults (n = 104) was assessed, and comparisons were made between heavy current to nonheavy drinkers (NIAAA criteria), lifetime AUD versus no-AUD, and older (>50 years) versus younger participants. Hierarchical regression analyses were conducted to examine the association between cognitive performance and current heavy drinking, lifetime AUD, and older age, while also correcting for HIV clinical factors and history of other substance use. RESULTS: Individuals reporting current heavy drinking and meeting criteria for lifetime AUD demonstrated the greatest degree of deficits across multiple cognitive domains. Deficits were greatest among HIV+ adults with lifetime AUD, and older age was also associated with weaker cognitive performance. Lifetime AUD and older age independently exhibited stronger associations with cognitive performance than HIV clinical factors (e.g., viral load, current CD4, and nadir CD4) or past opiate and cocaine use. CONCLUSIONS: Current heavy drinking and lifetime AUD adversely affect cognitive function in HIV+ adults. Greatest deficits existed when there was a history of AUD and continued current heavy drinking, indicating that past AUD continues to have an adverse impact and should not be ignored. That alcohol use was more strongly associated with cognitive performance than HIV clinical factors underscore clinical importance of targeting reduction in heavy alcohol consumption in HIV+ adults.

Alcohol use is a key risk factor for HIV infection among MSM, in part because intoxication may interfere with the use of prevention methods like condoms. However, few studies have examined whether this is due to alcohol's pharmacological or expectancy effects or explored the specific aspects of sexual decision-making that may be affected. In this study, high-risk, heavy drinking MSM (N = 121) were randomly assigned to receive either (1) alcohol beverages, (2) placebo beverages, or (3) control beverages, before navigating a video-based sexual risk scenario that assessed several aspects of sexual decision-making. Results showed that condom use intentions and negotiation behaviors were lower among alcohol and placebo participants compared with controls, but that few significant differences emerged between the alcohol and placebo groups. These findings contrast with similar past studies, and suggest that alcohol's expectancy effects may play a role in sexual decision-making.

AIMS: Chronic alcohol use is associated with cerebral metabolite abnormalities, yet alcohol's acute effects on neurometabolism are not well understood. This preliminary study investigated cerebral metabolite changes in vivo on the descending limb of blood alcohol in healthy moderate drinkers. METHODS: In a pre/post design, participants (N = 13) completed magnetic resonance imaging (MRI) scans prior to and approximately 5 hours after consuming a moderate dose of alcohol (0.60 grams alcohol per kilogram of body weight). Magnetic resonance spectroscopy (1H MRS) was used to quantify cerebral metabolites related to glutamatergic transmission (Glx) and neuroimmune activity (Cho, GSH, myo-inositol) in the thalamus and frontal white matter. RESULTS: Breath alcohol concentration (BrAC) peaked at 0.070±0.008% (mean ± standard deviation) and averaged 0.025±0.011% directly prior to the descending limb scan. In the thalamus, Glx/Cr and Cho/Cr were significantly elevated on the descending limb scan relative to baseline. BrAC area under the curve, an index of alcohol exposure during the session, was significantly, positively associated with levels of Glx/Cr, Cho/Cr and GSH/Cr in the thalamus. GSH/Cr on the descending limb was inversely correlated with subjective alcohol sedation. CONCLUSIONS: This study offers preliminary evidence of alcohol-related increases in Glx/Cr, Cho/Cr and GSH/Cr on the descending limb of blood alcohol concentration. Findings add novel information to previous research on neurometabolic changes at peak blood alcohol in healthy individuals and during withdrawal in individuals with alcohol use disorder.

"Just-in-time" interventions (JITs) delivered via smartphones have considerable potential for reducing HIV risk behavior by providing pivotal support at key times prior to sex. However, these programs depend on a thorough understanding of when risk behavior is likely to occur to inform the timing of JITs. It is also critical to understand the most important momentary risk factors that may precede HIV risk behavior, so that interventions can be designed to address them. Applying machine learning (ML) methods to ecological momentary assessment data on HIV risk behaviors can help answer both questions. Eighty HIV-negative men who have sex with men (MSM) who were not on PrEP completed a daily diary survey each morning and an experience sampling survey up to six times per day via a smartphone application for 30 days. Random forest models achieved the highest area under the curve (AUC) values for classifying high-risk condomless anal sex (CAS). These models achieved 80% specificity at a sensitivity value of 74%. Unsurprisingly, the most important contextual risk factors that aided in classification were participants' plans and intentions for sex, sexual arousal, and positive affective states. Findings suggest that survey data collected throughout the day can be used to correctly classify about three of every four high-risk CAS events, while incorrectly classifying one of every five non-CAS days as involving high-risk CAS. A unique set of risk factors also often emerge prior to high-risk CAS events that may be useful targets for JITs.

BACKGROUND: Timeline Followback (TLFB) interview methods are used to assess a variety of health behaviors, including alcohol use, drug use, and sexual behavior. While several online TLFBs have been developed, most focus on single behaviors, and few studies have explored their validity in assessing multiple risk behaviors using a single online TLFB. OBJECTIVE: To examine the validity of a customizable web application (Timeline) for assessing alcohol use, drug use, and sexual behavior among high-risk men who have sex with men. METHODS: Participants (N = 15 men) completed standardized survey instruments before undergoing a 30-day daily diary procedure where they submitted daily reports of health risk behaviors via smartphone. They then completed a Timeline at the end of the 30-day period covering the same time interval. RESULTS: Comparing a baseline administration of Timeline with popular surveys of health risk behaviors supported Timeline's validity (r = 0.41-0.59 for alcohol use, r = 0.83 for drug use, and r = 0.34-0.52) for sexual behaviors. While participants reported similar amounts of each behavior via daily diary as they did on a follow-up Timeline (r = 0.55-0.88 for alcohol use, r = 0.69 for drug use, and r = 0.87-0.92 for sexual behaviors), results provided evidence of underreporting on the Timeline. Timing of behaviors also frequently disagreed across these methods. CONCLUSIONS: Timeline is valid for assessing overall engagement in alcohol use, drug use, and sexual behavior over a 30-day window. However, researchers interested in the specific timing of behaviors within assessment intervals should use smaller follow-up intervals (e.g., 7 days, 14 days) or more intensive reporting methods (e.g., daily diary).

OBJECTIVE: We investigated the technical model of motivational interviewing (MI) in a dual-outcome intervention (i.e., alcohol, sexual risk; N = 164; 57% female). METHOD: We identified latent classes of client change statements, based on the proportion of change talk (CT) over the session. We then examined whether outcomes were related to CT class, and whether the relations between MI skill and outcomes varied by CT class. RESULTS: We found three classes of alcohol-CT and two classes of sexual risk-CT. While CT class membership did not predict outcomes directly, greater therapist MI-consistent skill was associated with fewer heavy drinking days in the increasing alcohol-CT class. For sexual risk outcomes, therapist MI-consistent skill was associated with reduced odds of condomless sex for the low sexual risk-CT class. CONCLUSIONS: The relation of therapist MI consistency to outcomes appears to be a function of client CT during the session.

BACKGROUND: Interventions aimed at reducing co-occurring heavy drinking and risky sexual behavior among Emergency Department (ED) patients require feasibility and acceptability to optimally engage individuals. OBJECTIVES: This pilot study explored the feasibility and acceptability of an interactive text-messaging (TM) supplement to a brief in-person intervention previously found successful in reducing alcohol use and condomless sex. METHODS: Using a mixed-method design, ED patients with past hazardous alcohol use and condomless sex (N= 20) were randomly assigned to receive either a Motivational Intervention + TM or Brief Advice + TM. All participants completed exit interviews at four weeks follow-up, and transcripts were transcribed and coded to identify themes. We evaluated feasibility through quantitative assessment of TM response rates and latency to response, while acceptability was evaluated through thematic analysis of exit interviews. RESULTS: Findings provide support for the delivery of an integrated and personalized MI and TM. Participants engaged positively with the TM intervention and qualitative interviews offered strong support for the acceptability while offering information necessary to enhance the TM component. CONCLUSIONS: Integrating MI with TM is feasible and acceptable to at-risk ED patients and could facilitate behavior changes beyond MI alone.
RESUMO
Men who have sex with men (MSM) continue to be at especially high risk for HIV in the United States. Past studies have shown that rates of HIV testing differ across a number of demographic and behavioral factors, and this research may be helpful for targeting efforts to increase testing among certain subgroups of MSM. In this study, MSM were recruited from several online sources to complete a questionnaire on HIV testing. Generalized ordered logit models suggested that the odds of having tested within the last 12 months were higher among racial/ethnic minority MSM, those with a college degree, and those who engaged in more recent HIV-risk behavior. The odds of having tested within the last 12 months were also higher among those who reported having sex with a partner they met online in the last 12 months. Conversely, the odds of having tested in the last 12 months were lower among those who reported drinking alcohol heavily, when compared with more moderate drinkers, highlighting yet another potential impact of alcohol on HIV outcomes.

HIV-related "cognitive escape" refers to a tendency to avoid thoughts associated with HIV, which may be particularly common among men who have sex with men (MSM) who are often inundated with HIV information, potentially to the point of fatigue. HIV-related cognitive escape is associated with increased sexual risk behaviors, such as condomless sex, and heavier alcohol use patterns. Other studies show that some MSM may use alcohol specifically to facilitate sex. These sexual motives for drinking (SMDs) could be one mechanism whereby cognitive escape leads to health risk behaviors. In this study, we tested models exploring whether cognitive escape was associated with markers of sex risk (condom use, number of sex partners) and alcohol use/problems, and examined whether SMDs mediated these associations. Heavy drinking, HIV-negative men (N = 196) aged ≥ 21 years who self-reported past year condomless anal sex with men completed assessments as part of a larger study. Results suggest that cognitive escape was associated with higher number of anal sex partners (incidence rate ratio [IRR] = 1.50, SE = 0.04, p < .001), decreased condom use (B = -0.30, SE = 0.14, p = .028), and increased alcohol-related problems (IRR = 1.28, SE = 0.07, p = .001) but not with drinking quantity. Sexual motives for drinking appeared to partially mediate the observed relationship between cognitive escape and alcohol-related problems, but other relationships did not show evidence of mediation. Findings suggest that those who tend to avoid HIV-related thoughts may be at increased risk for HIV and alcohol-related problems. Drinking to facilitate sex may partially account for the higher risk for alcohol-related problems conferred by cognitive escape. Alcohol interventions for MSM may be more effective if they address alcohol's role in coping with HIV threat and in facilitating sex under these circumstances.

Brief interventions (BI) for alcohol use in the emergency department (ED) have been shown efficacious among adolescents and young adults; however, whether these interventions extend to other outcomes - proximal and distal - are less explored. This study examined outcomes of ED BIs in four completed trials showing reductions in alcohol use. Limited and inconsistent effects were found on proximal outcomes including parental monitoring, and distal outcomes including tobacco use. Identifying the mechanisms that underlie alcohol-focused BIs as well the intervention processes that may lead to generalized, positive effects on other variables is an important area of future research.
