Targeted Oral Naltrexone for Mild to Moderate Alcohol Use Disorder Among Sexual and Gender Minority Men: A Randomized Trial.

ABSTRACT:

Objective

The authors sought to determine the efficacy of targeted naltrexone in sexual and gender minority men (SGM) who binge drink and have mild to moderate alcohol use disorder.

Methods

In a double-blind placebo-controlled trial, a total of 120 SGM who binge drink and have mild to moderate alcohol use disorder were randomized in a 1:1 ratio to receive targeted oral naltrexone (50 mg) or placebo with weekly counseling for 12 weeks. The study's primary endpoints were binge-drinking intensity, defined as 1) number of drinks in the past 30 days; 2) any binge drinking in the past week; 3) number of binge-drinking days in the past week; and 4) number of drinking days in the past week. The study also measured changes in alcohol use with two alcohol biomarker measures: ethyl glucuronide in urine samples and phosphatidylethanol (PEth) in dried blood spot samples.

Results

Ninety-three percent completed the trial, with 85% of weekly follow-up visits completed. In intention-to-treat analyses, naltrexone was associated with a significantly reduced reported number of binge-drinking days (incidence rate ratio [IRR]=0.74, 95% CI=0.56, 0.98; number needed to treat [NNT]=2), weeks with any binge drinking (IRR=0.83, 95% CI=0.72, 0.96; NNT=7.4), number of drinks per month (IRR=0.69, 95% CI=0.52, 0.91; NNT=5.7 for 10 drinks), and alcohol craving scores (coefficient=-9.25, 95% CI=-17.20, -1.31). In as-treated analyses among those who took their medication on average at least 2.5 days per week (the median frequency in the study), naltrexone reduced any binge drinking (IRR=0.84, 95% CI=0.71, 0.99), number of binge-drinking days (IRR=0.67, 95% CI=0.47, 0.96), and PEth concentrations (coefficient=-55.47, 95% CI=-110.75, -0.20). At 6 months posttreatment, naltrexone had sustained effects in number of drinks per month (IRR=0.69, 95% CI=0.50, 0.97), number of binge-drinking days (IRR=0.67, 95% CI=0.47, 0.95), and any binge drinking in the past week (IRR=0.79, 95% CI=0.63, 0.99).

Conclusions

Targeted naltrexone significantly reduced drinking outcomes among SGM with mild to moderate alcohol use disorder during treatment, with sustained effects at 6 months posttreatment. Naltrexone may be an important pharmacotherapy to address binge drinking in populations with mild to moderate alcohol use disorder.

Project description:Disparities in HIV incidence and PrEP uptake suggest a need to prioritize Black sexual minority men (SMM) in PrEP social marketing initiatives. However, images linking Black SMM to HIV and PrEP may inadvertently reinforce stigma. We examined HIV-negative/status-unknown Black SMM's responses to targeted PrEP advertisements using mixed methods, including an experiment embedded in a longitudinal online survey (Time 1: n = 96; Time 2 [eight weeks]: n = 73) and four focus groups (n = 18). The full factorial experiment included between-groups and within-subjects comparisons. For between-groups comparisons, each participant was randomly assigned to view one of 12 advertisements, which varied by couple composition (Black SMM couple/Black heterosexual couple/multiple diverse couples/no couples) and campaign (PrEPare for the Possibilities/PlaySure/PrEP4Love). We examined couple composition, campaign, and interaction effects on: advertisement judgments (Time 1), PrEP stigma (Time 1), PrEP motivation (Times 1 and 2), and PrEP behavior (Time 2). For within-subjects comparisons, each participant viewed all 12 advertisements, and we examined couple composition, campaign, and interaction effects on advertisement judgments (Time 2). Focus group participants discussed advertising preferences and responded to the same set of advertisements. For between-groups and within-subjects comparisons, we found significant couple composition effects but no or limited campaign and interaction effects on advertisement judgments. Advertisements featuring Black SMM exclusively were judged as more stigmatizing than advertisements without couples. Advertisements with diverse (vs. no) couples were considered more eye-catching and motivating. There were minimal effects of couple composition and campaign on PrEP stigma, motivation, and behavior. Focus group participants corroborated concerns about the potential for PrEP advertisements to be stigmatizing, suggesting advertisements featuring Black SMM exclusively could be alienating and fuel conspiracy theories. Focus group participants generally favored diverse and less sexualized advertisements, particularly for public spaces. Findings collectively highlight the potential for targeted PrEP advertisements to stigmatize Black SMM and support diverse representation.

Project description:Sexual and gender minority (SGM) adolescents report higher rates of dating violence victimization compared with their heterosexual and cisgender peers. Research on dating violence often neglects diversity in sexual and gender identities and is limited to experiences in relationships. Further, given that dating violence and alcohol use are comorbid, research on experiences of dating violence could provide insights into alcohol use disparities among SGM adolescents. We aimed to map patterns of relationship experiences, sexual and physical dating violence, and sexual and physical assault and explored differences in these experiences among SGM adolescents. Further, we examined how these patterns explained alcohol use. We used a U.S. non-probability national web-based survey administered to 13-17-year-old SGM adolescents (N = 12,534). Using latent class analyses, four patterns were identified: low relationship experience, dating violence and harassment and assault (72.0%), intermediate dating experiences, sexual harassment, and assault and low levels of dating violence (13.1%), high dating experiences, dating violence, and sexual assault (8.6%), and high dating experiences, dating violence, and sexual harassment and assault (6.3%). Compared to lesbian and gay adolescents, bisexual adolescents reported more experiences with dating, dating violence, and sexual assault, whereas heterosexual adolescents reported fewer experiences with dating, dating violence, and sexual harassment and assault. Compared to cisgender boys, cisgender girls, transgender boys, and non-binary/assigned male at birth adolescents were more likely to experience dating violence inside and outside of relationship contexts. Experiences of dating, dating violence, and sexual harassment and assault were associated with both drinking frequency and heavy episodic drinking. Together, the findings emphasize the relevance of relationship experiences when studying dating violence and how dating violence and sexual harassment and assault might explain disparities in alcohol use.

Project description:BackgroundThe mpox outbreak resulted in 32,063 cases and 58 deaths in the United States and 95,912 cases worldwide from May 2022 to March 2024 according to the US Centers for Disease Control and Prevention (CDC). Like other disease outbreaks (eg, HIV) with perceived community associations, mpox can create the risk of stigma, exacerbate homophobia, and potentially hinder health care access and social equity. However, the existing literature on mpox has limited representation of the perspective of sexual minority men and gender-diverse (SMMGD) individuals.ObjectiveTo fill this gap, this study aimed to synthesize themes of discussions among SMMGD individuals and listen to SMMGD voices for identifying problems in current public health communication surrounding mpox to improve inclusivity, equity, and justice.MethodsWe analyzed mpox-related posts (N=8688) posted between October 2020 and September 2022 by 2326 users who self-identified on Twitter/X as SMMGD and were geolocated in the United States. We applied BERTopic (a topic-modeling technique) on the tweets, validated the machine-generated topics through human labeling and annotations, and conducted content analysis of the tweets in each topic. Geographic analysis was performed on the size of the most prominent topic across US states in relation to the University of California, Los Angeles (UCLA) lesbian, gay, and bisexual (LGB) social climate index.ResultsBERTopic identified 11 topics, which annotators labeled as mpox health activism (n=2590, 29.81%), mpox vaccination (n=2242, 25.81%), and adverse events (n=85, 0.98%); sarcasm, jokes, and emotional expressions (n=1220, 14.04%); COVID-19 and mpox (n=636, 7.32%); government or public health response (n=532, 6.12%); mpox symptoms (n=238, 2.74%); case reports (n=192, 2.21%); puns on the naming of the virus (ie, mpox; n=75, 0.86%); media publicity (n=59, 0.68%); and mpox in children (n=58, 0.67%). Spearman rank correlation indicated significant negative correlation (ρ=-0.322, P=.03) between the topic size of health activism and the UCLA LGB social climate index at the US state level.ConclusionsDiscussions among SMMGD individuals on mpox encompass both utilitarian (eg, vaccine access, case reports, and mpox symptoms) and emotionally charged (ie, promoting awareness, advocating against homophobia, misinformation/disinformation, and health stigma) themes. Mpox health activism is more prevalent in US states with lower LGB social acceptance, suggesting a resilient communicative pattern among SMMGD individuals in the face of public health oppression. Our method for social listening could facilitate future public health efforts, providing a cost-effective way to capture the perspective of impacted populations. This study illuminates SMMGD engagement with the mpox discourse, underscoring the need for more inclusive public health programming. Findings also highlight the social impact of mpox: health stigma. Our findings could inform interventions to optimize the delivery of informational and tangible health resources leveraging computational mixed-method analyses (eg, BERTopic) and big data.
