Prevalence and correlates of hazardous alcohol consumption and binge drinking among men who have sex with men (MSM) in San Francisco

Substance Use Classes Among YMSM in an HIV Digital Health Intervention Program: Implications for Acceptability, Engagement, and Health Outcomes

Young men who have sex with men (YMSM) have high rates of substance use, which increases their risk for HIV. Digital Health Interventions (DHI) have the potential to address HIV risk overall and reduce harms in the context of substance use. However, there is limited research on how YMSM with different substance use patterns respond to HIV DHIs and how these programs impact participant outcomes. In this study, we used latent class analysis (LCA) to identify subgroups of participants with specific substance use behaviors in the Keep It Up! (KIU! ) program, an HIV DHI with prior documented effectiveness. This study involved 2,124 participants in a Type III Hybrid trial, comparing two implementation strategies: one via 22 community-based organizations and another through direct-to-consumer recruitment. Evaluations were done at baseline and 12-week follow-up. This analysis identified four classes of substance use: Low Use (minimal alcohol risks, low illicit drug use, infrequent marijuana), Heavy Use (highest alcohol problems, frequent marijuana, elevated illicit drug use), Alcohol and Marijuana Use (high alcohol problems, frequent marijuana), and Methamphetamine and GBH Use (low alcohol risk, moderate marijuana frequency, high illicit drug use). Participants in the Meth & GHB User class were more likely to have an STI at baseline compared to those in the Low User class. Moreover, Heavy Use, Alcohol & Marijuana Use, and Meth & GHB Use reported a greater number of condomless anal sex partners compared to Low Use. Additionally, although Alcohol & Marijuana Use were more likely to use PrEP at the time of their most recent casual partner at baseline, they exhibited the smallest increase in PrEP use during follow-up compared to the other substance use classes. Our analysis did not unveil substantial differences in the success of implementation in terms of reach, suggesting that both implementation strategies effectively engaged YMSM with different levels of substance use. Our research showed a similar level of engagement, as evidenced by the completion rates of modules and time spent, across all substance use classes. However, those within the Meth & GHB category found the intervention highly acceptable, but less so compared to Low Use and Alcohol & Marijuana Use. Understanding how distinct substance use profiles influence intervention outcomes and exploring varied implementation methods can augment future prevention endeavors, broadening the scope and impact of public health initiatives.

Assessing the Risk of Sexually Transmitted Infections among Men who have Sex with Men in San Francisco during COVID-19: A Socio-ecological Analysis

BACKGROUND

Men who have sex with men (MSM) are disproportionately affected by sexually transmitted infections, a disparity that has only worsened in recent years. During the COVID-19 pandemic, an overall increasing trend remained.

METHODS

We utilized data from the MSM cycle of the National HIV Behavioral Surveillance (NHBS) study in San Francisco, California, conducted from June 2021 through December 2021, to identify socio-ecological disruptions during the COVID-19 pandemic that were associated with sexually transmitted infections.

RESULTS

In total, 505 participants were surveyed, and approximately 24% of the participants reported having been diagnosed with an STI infection within the past 12 months. In the adjusted Poisson regression models, socio-ecologic factors that were independently associated with STI infection included barriers to STI testing due to COVID-19 (aRR 1.62, 95% CI 1.18-2.23), sex with partners part of small social circles/pods (aRR 2.41, 95% CI 1.41-4.12), sex with partners whose risk for COVID-19 was not known (aRR 3.53, 95% CI 2.05-6.06), and an increase or relapse in recreational substance use (aRR 2.01, 95% CI 1.49-2.72).

CONCLUSIONS

These findings indicate the importance of enacting comprehensive policies that not only address an ongoing global pandemic but also consider its potential effects on other public health epidemics, such as sexually transmitted infections among men who have sex with men.

The influence of tobacco use, hazardous drinking, and other risk factors on HPV-associated oropharyngeal cancer risk and screening perceptions among gay and bisexual men: a cross-sectional study

BACKGROUND

Oropharyngeal cancer is the eighth most common cancer among US men and its incidence is sharply rising. Oropharyngeal cancer manifests in two major ways: the classic form is prevalent among people who use alcohol and tobacco heavily, while a growing subset of incident cases is associated with human papillomavirus-16 (HPV) and transmitted via oral sex. Gay and bisexual men appear at higher risk for each etiologic subset of oropharyngeal cancer than heterosexual men. We conducted a cross-sectional study to learn how tobacco use, hazardous drinking, and other key risk factors affect gay and bisexual men's perceptions of oropharyngeal cancer risk and beliefs about screening at a doctor's office and self-screening at home.

METHODS

We recruited 1,699 gay and bisexual men from two dating websites to participate in an online survey. We asked about tobacco use, alcohol consumption, sexual history, and other risk factors for oropharyngeal cancer. The survey also investigated participants' perceptions of oropharyngeal cancer risk and potential worry related to screening. We analyzed results at the bivariate level and in multivariable regression models. We used logistic regression to analyze categorical data and linear regression to analyze continuous data.

RESULTS

Average age of participants was 41.5 (SD = 12.7) years. Most were cisgender (95%), and identified as gay (80%), while 19% were bisexual or pansexual, with 2% reporting being queer or a self-described sexuality. Factors associated with high perceived oropharyngeal cancer risk perceptions were cigarette smoking, using both cigarettes and vaping, being gay identified, number of sexual partners in the last 12 months, and having poor mouth/teeth condition. Factors associated with oropharyngeal cancer screening worry were being Hispanic, having queer/self-described sexuality, not having health insurance, and having poor mouth/teeth condition. No factors were associated with self-screening at home. Alcohol use was not associated with oropharyngeal cancer risk perception.

CONCLUSIONS

This study examines oropharyngeal cancer risk perceptions among gay and bisexual men. Health promotion efforts to reduce oropharyngeal cancer risk among gay and bisexual men should involve comprehensive oral health, sexual health, and tobacco use education. Researchers should continue investigating acceptable and effective home self-screening methods for HPV-associated cancers.

Sexual Racism and Queer Asian American Men's Depression and Hazardous Drinking

While research suggests that sexual racism is prevalent within the gay community, studies have neglected to examine how this specific manifestation of racism influences queer Asian American men's mental health. Queer Asian American men's health outcomes are often overlooked as racism-related studies tend to homogenize queer Asian American men with queer men of color broadly. Thus, the present study examined the association between sexual racism and queer Asian American men's depressive symptomatology and hazardous drinking, as well as the moderating role of collective racial self-esteem. The final sample consisted of 151 queer Asian American men who completed a 30-minute cross-sectional survey. Regression analyses indicated that sexual racism was positively associated with depressive symptomatology, whereas it was not associated with hazardous drinking. Additionally, collective racial self-esteem was not found to have a moderating effect. These findings underscore the necessity of racial justice-promoting interventions to minimize queer Asian American men's experience of sexual racism in gay communities. Results also highlight the importance of developing culturally congruent training for clinicians working with queer Asian American men to gain an understanding of how sexual racism impacts this population.

Syndemic conditions associated with hazardous alcohol consumption among sexual minority men in San Francisco

Background

Hazardous alcohol consumption (HAC) is prevalent among sexual minority men (SMM). Using syndemic theory, this study aimed to identify the number of syndemic conditions, including their combinations, and their association with HAC among SMM in San Francisco.

Method

We conducted a secondary analysis of cross-sectional data from 246 SMM who consume alcohol. Syndemic factors included multiple substance use, depressive symptoms, HIV/STI status, and houselessness. We conducted a multivariable logistic regression to estimate the odds of HAC associated with increasing syndemic conditions. We further examined which combinations of three syndemic factors were associated with the highest odds for HAC.

Results

The average age was 40.7; participants were predominantly White (33.3 %) and Black/African American (29.7 %) and graduated from high school (92.7 %). The prevalence of HAC increased with the number of syndemic conditions: 13.6 % with none, 30.9 % with one, 51.9 % with two, 65.1 % with three, and 69.2 % with four conditions. A significant log-linear trend was observed, with two syndemic conditions increasing the odds of HAC over fivefold (AOR=5.05, 95 % CI=1.68-15.15), and three and four syndemic conditions increasing the odds by more than eightfold (AOR=8.82, 95 % CI=2.74-28.39; AOR=8.55, 95 % CI=2.26-32.28). The combination of depressive symptoms, HIV/STI status, and houselessness tripled the odds for HAC (OR=3.07, 95 % CI=1.34-7.04).

Conclusion

HAC was associated with increasing syndemics, and specific conditions (depression, HIV/STI, and houselessness) had the greatest odds of HAC. These findings underscore the need for comprehensive screening and integrated interventions targeting these co-occurring conditions to reduce HAC in this population.

Interest in the Use of Herbal Supplements to Close the Treatment Gap for Hazardous Alcohol Use Among Men Who Have Sex With Men: Secondary Analysis of a Cross-Sectional Study

BACKGROUND

Hazardous alcohol consumption is highly prevalent for men who have sex with men (MSM). The 4 treatments currently approved by the Food and Drug Administration for alcohol use are reaching an alarmingly low percentage of people who would benefit from a reduction in their alcohol use. There is increasing interest in alternative methods of treatment, such as herbal supplements, to address hazardous drinking. However, research on the acceptability of alternative pharmacotherapies among MSM remains limited.

OBJECTIVE

We examined the prevalence and correlates of expressing interest in using herbal supplements for alcohol treatment among MSM with hazardous alcohol consumption.

METHODS

We conducted a secondary data analysis from a cross-sectional study of MSM who use alcohol, conducted from March 2015 to July 2017 in San Francisco, California, to assess the overall prevalence of interest in using herbal supplements to help reduce alcohol consumption. Associations between expressing interest in herbal supplements and demographic, social, and clinical characteristics were examined using bivariate and multivariable logistic regression models.

RESULTS

One-third (66/200, 33%) of the participants expressed interest in an herbal supplement for reducing alcohol consumption. In the multivariable analyses, weekly binge drinking (adjusted odds ratio [aOR] 2.85, 95% CI 1.17-6.93), interest in abstaining from alcohol use (aOR 5.04, 95% CI 1.46-17.40), higher severity of alcohol dependence score (aOR 1.22, 95% CI 1.04-1.41), and interest in naltrexone (aOR 3.22, 95% CI 2.12-4.91) were independently associated with higher odds of being interested in using an herbal supplement to reduce alcohol consumption, adjusting for age, race or ethnicity, and education.

CONCLUSIONS

We found that MSM who have hazardous drinking habits, more severe alcohol dependence, and interest in pharmacotherapy were more likely to express interest in using an herbal supplement for reducing alcohol consumption. To our knowledge, this is the first study that has evaluated correlates of interest in herbal supplements for alcohol use among MSM. As researchers implement novel alcohol treatment studies, they should focus on recruitment efforts among MSM with a motivation to reduce their alcohol use patterns.

Alcohol Use Disorder and HIV Risk in a National Survey of Men Who Have Sex with Men in Ukraine

BACKGROUND

Problematic alcohol consumption is associated with risk behaviors associated with HIV transmission. Despite the high prevalence of problematic alcohol consumption in Ukraine, however, there are little empirical data examining its association with risk behaviors also associated with HIV transmission in men who have sex with men (MSM), a key population where HIV incidence is increasing, METHOD: Correlates of prevalent HIV infection and their association between drinking severity levels and behaviors also associated with increased likelihood of HIV acquisition were analyzed from a 2017 nationally representative survey (IBBS) of 4938 MSM in Ukraine using bivariate analyses and multivariate regression.

RESULTS

Overall, 42.6% of MSM participants met screening criteria for alcohol use disorder (AUD), with 24.2%, 12.0%, and 6.3% meeting criteria for moderate, high, and severe risk of harm from alcohol consumption, respectively. Multivariate regression revealed that these risk categories were correlated with behaviors associated with increased HIV transmission risk, including reports of (1) > 5 sexual partners; (2) sex with a partner of unknown HIV status; (3) sex work; (4) any drug use; and (5) not testing for HIV (past year). HIV testing was infrequent, with only 44.1% having been tested in the previous year.

CONCLUSION

The high prevalence of problematic alcohol use in Ukrainian MSM and its association with behaviors also associated with HIV transmission supports the importance of routine screening of MSM for AUD. Moreover, among those screening positive for a potential AUD, targeted HIV prevention strategies to scale-up pre-exposure prophylaxis, consistent condom use, and treatment for AUD are needed.

Patterns and Factors Associated With Alcohol Misuse Among Young Black Men Who Have Sex With Men in New York City

Alcohol misuse is a significant health concern among gay, bisexual, same-gender-loving, and other men who have sex with men (MSM). Yet, little is known about the severity and predictors of alcohol misuse among self-reported young Black MSM. This study aimed to identify patterns of and factors associated with alcohol misuse in a sample of young Black MSM living in New York City. Baseline data from a randomized controlled trial aimed at improving the uptake of HIV testing among 250 MSM aged 18 to 29 were analyzed. Log-binominal regression analyses were conducted to assess the association of demographic and psychosocial factors with alcohol misuse in the past year and past 3 months among young Black MSM. Overall, 33.2% and 28.0% of young Black MSM in the study experienced alcohol misuse in the past year and past 3 months, respectively. In the adjusted model, factors positively associated with past-year alcohol misuse included marijuana use, a history of drug use, and having one-two or more than two male sex partners. Likewise, participants who used marijuana and those with one-two or more than two male partners were more likely to report past 3-month alcohol misuse. No significant association was found between positive screening for depressive symptoms, chemsex, internalized homophobia, and the likelihood of having alcohol misuse. The high prevalence of alcohol misuse underscores the importance of raising awareness of alcohol misuse and designing alcohol risk reduction programs that jointly address HIV risk among young Black MSM.

Racial/Ethnic Disparities in Club Drug Use, Situational Club Drug Use during Sex, and Sexual Risk Behaviors among Alcohol-Using Men Who Have Sex with Men (MSM) in San Francisco

BACKGROUND

Club drug use-including 3,4-Methylenedioxymethamphetamine, ketamine, crack/cocaine, hallucinogens, gamma hydroxybutyrate, volatile nitrites, and methamphetamine-has been linked to sexual risk behaviors among MSM. Few studies examine how the use of club drugs and the association between club drug use during sex and sexual risk may differ by race/ethnicity.

METHODS

Using data from a cross-sectional study among alcohol-using MSM in San Francisco (n = 252), we examined the associations between the interaction of race/ethnicity and club drug use during sex, and the following behavioral outcomes: any condomless anal intercourse (CAI), insertive CAI, receptive CAI, and any serodiscordant sex in the past six months. All models controlled for income, HIV status, relationship status, age, and current use of a biomedical HIV prevention tool (i.e., Pre-Exposure Prophylaxis [PrEP] or antiretroviral therapy).

RESULTS

There were significant racial differences in club drug use (p < 0.001) and club drug use during sex (p = 0.01). Asian/Pacific Islander (API) and Latino participants reported using club drugs the most at 78.8% and 79%, respectively. Among users of club drugs, club drug use during sex was most common among Black (100%), and Latino MSM (93%). Significant interactions between race/ethnicity and club drug use during sex were observed for CAI (p = 0.02), insertive CAI (p = 0.01), and receptive CAI (p = 0.01). API participants who used club drug during sex had higher odds of reporting CAI (aOR = 15.27, CI = 1.50-155.34), insertive CAI (aOR = 21.11, CI = 2.04-218.10), and receptive CAI (aOR = 21.11, CI = 2.04-218.10).

CONCLUSIONS

Given the differing rates of club drug use during sex by race/ethnicity and the role race/ethnicity plays in modifying the relationships between club drug use during sex and sexual risk behaviors, culturally-tailored interventions may be needed to address the needs of ethnically-diverse, club drug-using MSM.

Stimulant Use Associated With Psychosocial Factors, HIV Risk, and Concurrent Hazardous Alcohol Use Among US Adults: Exploratory Cross-Sectional Questionnaire Study

BACKGROUND

Stimulant use is a major public health problem that contributes to morbidity and mortality among men who have sex with men (MSM) in the United States. To reduce the harms associated with stimulant use, there is a need to identify the factors associated with stimulant use to inform interventions. Additionally, there is a need to use large crowdsourcing platforms like Amazon Mechanical Turk (MTurk) to engage more individuals who use substances across the United States.

OBJECTIVE

We identified the correlates of stimulant use among people who use alcohol or stimulants in the United States recruited using MTurk.

METHODS

Participants who were aged ≥18 years in the United States and reported alcohol or stimulant (ie, cocaine, crack cocaine, and methamphetamine) use were deemed eligible and recruited via the web platform MTurk. Participants completed a baseline survey, which assessed sociodemographics, psychosocial (ie, depression, affect, self-esteem, and stress) factors, substance use, and sexual behaviors. Data were collected and analyzed with STATA (version 17; StataCorp). Stratifying by MSM status, bivariate and multivariable logistic regression models were built in STATA to examine the correlates of stimulant use. Multivariable models controlled for age, race, health insurance, and relationship status.

RESULTS

Of 272 participants, 201 (73.9%) identified as male, 134 (49.2%) were MSM, 52 (19.1%) were from racial and ethnic minoritized communities, and 158 (58%) were in a relationship. The mean age was 36.10 (SD 10.3) years. A total of 40 (14.7%) participants reported stimulant use in the past 6 months. Factors significantly associated with stimulant use were being MSM (adjusted odds ratio [aOR] 4.61, 95% CI 1.97-10.81), a higher Alcohol Use Disorders Identification Test-Concise score (aOR 1.24, 95% CI 1.08-1.42), more intense cravings for alcohol in the past 24 hours (aOR 1.03, 95% CI 1.01-1.04), a higher depression score (aOR 1.06, 95% CI 1.01-1.12), a greater number of male partners in the last 6 months (aOR 1.32, 95% CI 1.08-1.61), a greater number of female partners in the last 6 months (aOR 1.42, 95% CI 1.04-1.92), and being diagnosed with a sexually transmitted infection (eg, syphilis, gonorrhea, chlamydia, herpes simplex virus, human papillomavirus, and other) in the last 6 months (aOR 14.61, 95% CI 3.45-61.87). Additionally, there was a significant additive interaction between MSM status and negative affect, such that the impact of negative affect on stimulant use was significantly greater among MSM compared with non-MSM (relative excess risk due to interaction 0.085, 95% CI 0.037-0.13).

CONCLUSIONS

Interventions that address stimulant use should use evidence-based approaches that reduce negative affect, depression, and cravings for alcohol. Additionally, interventions should be customized for MSM populations.

Binge Drinking Moderates Unprotected Sex Among HIV Sero-Similar Same Sex Male Couples: An Actor-Partner Interdependence Model

Most new HIV diagnoses in the US occur among sexual minority men (SMM). The majority (69%) of new HIV diagnoses among US SMM are due to transmission from main sex partners. We identified multilevel correlates of unprotected anal intercourse (UAI; condomless anal intercourse while not using a biomedical strategy) among SMM couples using the Actor Partner Interdependence Model (APIM). Participants were US SMM over 18 years, with a primary male partner > 6 months. Couples were recruited online from April 2016 until June 2017 and interviewed using self-administered computer-assisted surveys. We used a series of APIM regressions to assess multilevel associations with UAI. We also tested the moderating role of an individual's binge drinking on the relationship between HIV status similarity and UAI. Among 798 participants (n = 411 couples), 61% reported UAI in the past 6 months. Binge drinking (52%) and physical intimate partner violence (IPV; 34%) were considerably high within our sample. Actor's binge drinking, reporting experiencing and/or perpetrating physical IPV, and partner's trust were positively associated with UAI. Actor having other sexual partner(s), using illegal drugs (not marijuana), and length of relationship were negatively associated with UAI. Binge drinking positively moderated UAI among HIV serostatus similar partners. HIV prevention programming should integrate components on IPV and binge drinking reduction- especially among HIV serostatus similar couples.

Anabolic Steroid Use and Intimate Partner Violence Among Sexual Minority Men

This study examined the relationship between intimate partner violence (IPV) and use of anabolic-androgenic steroids (AAS), in a relationship context, among men who have sex with men (MSM). The sample was collected online via Prolific.co and consisted of 491 MSM. Data were analyzed using structural equation modeling. While accounting for the influence of factors known to be linked to IPV (adverse childhood experiences and alcohol use), the use of AAS in a relationship context was uniquely linked to greater perpetration of IPV. AAS use was not uniquely linked to IPV victimization. Findings from this study contribute to literature on IPV among MSM by including a group-specific risk factor (AAS use) in modeling risk for IPV. Limitations, implications, and future directions for research are discussed.

Intersectional forms of racism and sexual minority stress are associated with alcohol use among Latinx sexual minority men with greater Hispanic/Latinx cultural orientation

Background: Latinx sexual minorities with increased levels of acculturation report higher rates of alcohol use, and discrimination may impact this association. Yet, there is little research examining the concomitant impact of racism and sexual minority stress (i.e. intersectional discrimination) and the additive effect of acculturation on Latinx sexual minority men's risk for hazardous alcohol consumption.Objectives: This study investigated the role of perceived stressfulness of intersectional discrimination in the relation between acculturation (US cultural orientation/Hispanic cultural orientation) and alcohol use among Latinx sexual minority men.Methods: A structural equation model was utilized to test the indirect effect of discrimination between acculturation and alcohol use with a sample of 357 Latinx sexual minority men (M_age = 28.39) recruited via Amazon MTurk.Results: The indirect effect between the Hispanic cultural orientation to alcohol use through intersectional forms of discrimination was significant and positive (b = .19, SE = .03, p < .01). The indirect effect for the US cultural orientation to alcohol use through intersectional forms of discrimination was significant and negative (b = -.10, SE = .03, p < .01).Conclusion: Contrary to previous literature, Latinx sexual minority men with a higher Hispanic cultural orientation reported higher levels of intersectional forms of discrimination, which in turn was associated with increased alcohol use. Those with a higher US cultural orientation reported lower levels of intersectional forms of discrimination, which in turn was associated with decreased alcohol use. These findings may help identify mechanisms that exacerbate health disparities for Latinx sexual minority men.

Prevalence of unprotected anal intercourse and associated factors among male students who have sex with men in Qingdao, China: A cross-sectional study

The significant rise of human immunodeficiency virus (HIV) epidemic among young students has become a new feature of acquired immune deficiency syndrome in China, and unprotected anal intercourse (UAI) among male students who have sex with men (SMSM) played a central role in this process. The aim of this study was to investigate the prevalence of UAI, as well as analyze the factors associated with UAI among SMSM in Qingdao, China. From May 2021 to April 2022, men who aged 15 to 30, studied in a high school or college in Qingdao and had anal sex with men in the past 6 months were recruited through snowball method relying on the nongovernmental organization. An anonymous electronic questionnaire was administrated to collect information on socio-demographic characteristics, sexual behaviors, substance use before sex, HIV prevention services and self-esteem. Univariate and multivariate logistic regressions were used to assess factors related to UAI. Among the 341 SMSM included in the study, 40.5% engaged in UAI in the past 6 months. Being migrants from other provinces [odds ratios (OR) = 2.04, 95% confidence intervals (CI): 1.10-3.78], failing to use condoms for the first anal intercourse (OR = 3.38, 95% CI: 1.85-6.18), drinking alcohol before sex (OR = 2.31, 95% CI: 1.25-4.28) and being low level self-esteem (OR = 1.77, 95% CI: 1.09-2.87) were positively associated with UAI. SMSM who had homosexual intercourse more than once a week (OR = 1.76, 95% CI: 1.03-3.00) or had multiple male sex partners (OR = 1.99, 95% CI: 1.20-3.30) were more likely to engage in UAI. Received peer education in the past 12 months (OR = 0.48, 95% CI: 0.27-0.86) was associated with lower odds of UAI. The situation of UAI among SMSM in Qingdao was a public health issue of concern. It is necessary to take targeted measures, such as focusing on first-time sex, advancing sexual health education, expanding peer education, implementing alcohol use screening and maintaining the self-esteem of SMSM, so as to reduce the occurrence of high-risk behaviors among SMSM and curb the spread of HIV on campus.

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

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.

Correlates of high phosphatidylethanol (PEth) levels and their concordance with self-reported heavy alcohol consumption among men who have sex with men who binge drink alcohol

BACKGROUND

Heavy alcohol use, including binge drinking, is associated with high morbidity and mortality among men who have sex with men (MSM). Self-reported alcohol measures may lead to inaccurate estimates due to recall and social desirability biases. Objective alcohol biomarkers like phosphatidylethanol (PEth) can be used to corroborate self-report and could help to inform treatment approaches and research strategies for alcohol using MSM.

METHODS

From 2015 to 2020, alcohol using MSM ≥18 years were enrolled in a randomized controlled trial evaluating the efficacy of naltrexone in reducing binge drinking. Using this trial's baseline data, we applied multivariable logistic regression to identify the correlates of high PEth levels (i.e., ≥87 ng/ml) and concordance between PEth levels and self-reported heavy drinking.

RESULTS

Of 118 MSM, 64% had PEth levels ≥87 ng/ml and 72% had PEth levels that were concordant with self-reported heavy alcohol use. Factors significantly associated in separate models with elevated PEth levels were income ≥$60,000 (adjusted odds ratio [aOR] = 4.09; 95% CI = 1.13 to 14.82), being employed (aOR = 4.04; 95% CI = 1.45 to 11.32), episodic cannabis use (aOR = 4.63; 95% CI = 1.27 to 16.92), and any alcohol/substance use prior to or during anal intercourse (aOR = 2.52; 95% CI = 1.08 to 5.90). Living with HIV was associated with significantly lower odds of elevated PEth levels (aOR = 0.23; 95% CI = 0.09 to 0.61). Factors associated with significantly higher concordance between PEth levels and self-reported heavy alcohol use included at least weekly use of poppers (aOR = 6.41; 95% CI = 1.27 to 32.28) and polysubstance use (aOR = 2.53; 95% CI = 1.02 to 6.27). Living with HIV was associated with lower odds of concordance (aOR = 0.36; 95% CI = 0.14 to 0.97).

CONCLUSIONS

PEth may enhance the detection of heavy drinking among MSM, including the identification of subpopulations that may benefit from targeted alcohol reduction interventions. However, PEth values for MSM living with HIV showed modest concordance with self-reported alcohol use and may need to be supplemented with additional biomarkers or evaluated against a different cutoff.

Risk Behaviors Associated with Patterns of Sexualized Stimulant and Alcohol Use among Men Who Have Sex with Men: a Latent Class Analysis

Substance use during sexual encounters (sexualized substance use) is an important driver of HIV and sexually transmitted infection (STI) disparities that are experienced by men who have sex with men (MSM). This analysis aimed to identify patterns of sexualized substance use and their associations with HIV risk behaviors. We utilized visit-level data from a longitudinal cohort of predominantly Black/Latinx MSM, half with HIV and half with substance use in Los Angeles, California. Every 6 months from 8/2014 to 3/2020, participants underwent STI testing and completed surveys on demographics, sexualized substance use (stimulant and/or alcohol intoxication during oral sex, receptive anal intercourse [RAI] and/or insertive anal intercourse [IAI]), transactional sex, biomedical HIV prevention (pre-/post-exposure prophylaxis use or undetectable viral load), and depressive symptoms. Latent class analysis was used to identify patterns of sexualized substance use. Multinomial logit models evaluated risk behaviors associated with latent classes. Among 2386 study visits from 540 participants, 5 classes were identified: no substance use, sexualized stimulant use, sexualized alcohol use, sexualized stimulant and alcohol use, and stimulant/alcohol use during oral sex and RAI. Compared to the no sexualized substance use class, sexualized stimulant use was associated with transactional sex, current diagnosis of STIs, not using HIV biomedical prevention, and depressive symptoms. Sexualized alcohol use had fewer associations with HIV risk behaviors. Patterns of sexual activities, and the substances that are used during those activities, confer different risk behavior profiles for HIV/STI transmission and demonstrate the potential utility of interventions that combine substance use treatment with HIV prevention.

Acceptability of Pre-Exposure Prophylaxis and Non-Occupational Post-Exposure Prophylaxis among Men Who Have Sex with Men in Guilin, China

Pre-exposure prophylaxis (PrEP) and non-occupational post-exposure prophylaxis (nPEP) are both effective strategies for preventing HIV. There is limited information about the acceptability of these prevention measures in undeveloped areas of China. We aimed to examine the acceptability of PrEP and nPEP and their determinants among men who have sex with men (MSM). 219 MSM were recruited in Guilin, China. In total, 28.6% (95% CI: 20.0-41.0) and 35.9% (95% CI: 27.3-49.5) of the participants had heard of PrEP and nPEP, respectively, while 57.0% (95% CI: 43.1-68.2) and 58.6 (95% CI:44.8-68.8) reported they would be willing to use PrEP and nPEP after the methods were explained. A higher acceptability of PrEP was seen among participants who were previously married (aOR = 3.30; 95% CI: 1.22-9.19), working as a laborer (aOR = 5.13; 95% CI: 1.64-17.59), migrant workers/farmers (aOR = 2.56; 95% CI: 1.15-5.79), government employees (aOR = 4.76; 95%CI: 1.80-13.02), had higher social support (aOR = 1.05; 95% CI: 1.03-1.08), and had been previously tested for HIV (aOR = 2.79; 95% CI: 1.36-5.94). A higher acceptability of nPEP was associated with those having higher social support (aOR = 1.06; 95% CI: 1.04-1.09), not knowing their sexual partner's HIV status (aOR = 2.72; 95% CI: 1.23-6.12), and having a prior HIV test (aOR = 5.53; 95% CI: 2.58-12.51). PrEP and nPEP are acceptable, especially among MSM with higher social support and had received a previous HIV test. Effective education and different dissemination strategies to promote the acceptance of PrEP and nPEP among MSM are needed.

Effects of mental health and substance use disorder symptoms on the association between STDs and sexual identity: evidence from the 2017–2019 National Survey on Drug Use and Health

Background

Sexually transmitted disease (STD) cases are rising in the USA, especially among sexual and gender minorities, despite the availability of numerous STD prevention programs. We examined the differences in STD prevalence among sexual and gender minority subgroups with major depressive episode symptoms and substance use dependence.

Methods

We combined 2017, 2018, and 2019 National Survey on Drug Use and Health (NSDUH) public-use data on adults (N = 127,584) to conduct weighted multivariable logistic regression and margins analyses.

Results

Approximately 2.05% of the population reported having STDs. The population that had major depressive episode symptoms (AOR = 1.70, 95% CI = 1.46, 1.99), alcohol use dependence (AOR = 1.79, 95% CI = 1.49, 2.16), illicit drug use other than marijuana use dependence (AOR = 2.25, 95% CI = 1.73, 2.92), or marijuana use dependence (AOR = 1.90, 95% CI = 1.57, 2.31) had higher odds of contracting STDs compared to their counterparts. Lesbian/gay (AOR = 2.81, 95% CI = 2.24, 3.54) and bisexual (AOR = 1.95, 95% CI = 1.60, 2.37) individuals had higher odds of contracting STDs. Lesbians/gays with major depressive episode symptoms, alcohol use dependence, or illicit drug use other than marijuana use dependence had the highest probability of having STDs, compared to bisexuals and heterosexuals with major depressive episode symptoms, alcohol use, or illicit drug use other than marijuana use dependence. Bisexuals with marijuana use dependence had the highest probability of STD contraction compared to their lesbian/gay and heterosexual counterparts. Within each sexual identity subgroup, the probability of having STDs was higher for individuals with major depressive episode symptoms, or dependence on alcohol use, illicit drug use other than marijuana use, or marijuana use compared to their counterparts.

Conclusion

Major depressive episode symptoms, substance use dependence, and sexual and gender minority status had higher risks for STD diagnosis, particularly for sexual and gender minorities with major depressive episode symptoms or substance use dependence. Tailored interventions based on major depressive episode symptoms and substance use dependence may reduce the prevalence of STD, especially among sexual and gender minorities.

Social and Behavioral Correlates of Sexually Transmitted Infections among Men who Have Sex with Men who Use Alcohol in the San Francisco Bay Area

The risk of acquiring sexually transmitted infections (STIs) among men who have sex with men (MSM) is driven by various socio-behavioral factors. From 2015-2017, 247 MSM ≥ 18 years-old who reported alcohol use in the past year, were recruited into a cross-sectional study in San Francisco. Participants completed a survey assessing socio-demographics, substance use and treatment, sexual behaviors, HIV status and self-reported STI diagnosis in the past 6 months. Multivariable logistic regression models stratified by HIV status were used to identify the correlates of STIs. Of 247 MSM, the prevalence of bacterial STIs were: gonorrhea (12.9%), chlamydia (9.3%) and syphilis (6.0%). Among 177 MSM living without HIV, factors significantly associated with recent STI diagnosis were: current pre-exposure prophylaxis (PrEP) use (aOR = 3.53, 95% CI: 1.42-8.75, p ≤ .01), popper use during sex in the past 6 months (aOR = 3.16, 95% CI = 1.34-7.47, p ≤ .01) and a history of alcohol treatment (aOR = 0.17, 95% CI = 0.04-0.68, p = .01). Also, in a sensitivity analysis (removing PrEP), any receptive condomless anal sex was independently associated with recent STI diagnosis (aOR = 2.86, 95% CI = 1.15-7.08, p = .02). Among 70 MSM living with HIV, factors significantly associated with recent STI diagnosis were: White race/ethnicity (adjusted odds ratio [aOR] = 7.36, 95% confidence interval [CI] = 1.48-36.62, p = .01), younger age (aOR = 0.90, 95% CI: 0.84-0.97, p < .01) and a higher number of male sexual partners in the past 6 months (aOR = 1.03, 95% CI = 1.00-1.06, p = .02). Sexual health interventions that address the unique needs of MSM living with and without HIV who use alcohol in San Francisco are needed to reduce STI acquisition and transmission.

Correlates of Alcohol-Using Network Size Among Men Who Have Sex with Men in San Francisco, CA

Men who have sex with men (MSM) have a high prevalence of hazardous alcohol consumption. While network-level characteristics such as social network size have been indicated as upstream determinants of alcohol use in general population samples, no studies have examined factors associated with alcohol using network size (ANS), among MSM.This secondary analysis examined demographic, substance use, and sexual behavior correlates of ANS using data from a diverse sample of alcohol-using MSM in San Francisco (N = 252). Associations were calculated using multivariable negative binomial regression, adjusting for age, race, education, and employment.The median ANS was 10. Factors associated with larger ANS in multivariable analyses included identifying as Hispanic/Latino, having completed a college education or higher, having a higher Alcohol Use Disorders Identification Test (AUDIT) score, having a greater number of sexual partners, polysubstance use, and being unaware of one's own HIV status. Factors associated with smaller ANS included being between 18 and 24 years of age, reporting a low income, and having any lifetime history of injection drug use.For MSM, ANS was associated with increased likelihood of hazardous alcohol use, as well specific individual-level substance use and sexual risk behaviors. These results highlight the role of ANS in hazardous alcohol consumption and sexually transmitted infection transmission among MSM. These results also indicate ways that research and intervention programs aimed at reducing alcohol use among MSM might be improved through network-based recruitment or engagement. Finally, these results suggest the need for further research on HIV-unknown MSM.

Alcohol consumption patterns among men who have sex with men in major cities of Myanmar: A cross-sectional study

Background: Alcohol consumption patterns vary widely across the regions of the world. Although previous studies have focused on the sexual risk behaviours among men who have sex with men (MSM), studies regarding binge alcohol drinking among MSM in Myanmar are scarce. Methods: A cross-sectional study was conducted to identify the alcohol consumption patterns among MSM aged over 18 years in two major cities of Myanmar where the MSM population is higher than other regions. Purposive sampling was applied and sampling was made through Myanmar MSM network. Face-to-face interviews were conducted using a structured questionnaire. Patterns of alcohol consumption were described as frequency/percentage and mean/median as appropriate. Bivariate analysis was also done to find out the association between types of MSM and binge drinking. Results: A total of 256 MSM included in the study (mean age, 27.33±7.7 years). Of 256 participants, 225 MSM had the experience of alcohol consumption in their lifetime (225/256, 87.9%). Among ever drinkers, 152 MSM consumed alcohol within three months (152/225, 67.6%). Regarding beer consumption, the highest proportions of MSM from both groups (42.8%, 36.8%) consumed 1-3 times per week. Overall, 57.2% of young MSM and 41.2% of adult MSM consumed beer together with their friends. Nearly 34% of young MSM and nearly 38% of adult MMS consumed beer at gatherings of friends. At different time periods, higher proportions of Thange (partners of MSM) had experienced of binge drinking than apwint (open) and apone (hidden) (p<0.05). Conclusions: The current study identified the alcohol consumption patterns in terms of type, amount, frequency at different time periods among MSM in major cities of Myanmar. It is suggested to develop and implement alcohol control policy for MSM since the proportion of current drinkers as well as binge drinking higher among these groups.

Bridging the Digital Divide Among Racial and Ethnic Minority Men Who Have Sex With Men to Reduce Substance Use and HIV Risk: Mixed Methods Feasibility Study

BACKGROUND

Ecological momentary assessment (EMA) is a promising data collection tool for mobile health interventions targeting episodic health behaviors. For substance-using men who have sex with men (SUMSM), EMA is becoming more widely utilized in efforts to characterize substance use and sexual risk factors for HIV transmission. However, recent literature demonstrates emerging concerns over compliance and lower EMA engagement and data concordance among racial and ethnic minority SUMSM.

OBJECTIVE

This study aimed to provide a qualitative evaluation of the barriers and facilitators of EMA as a data collection tool among racial and ethnic minority SUMSM.

METHODS

Between October and November 2017, 45 racial and ethnic minority SUMSM were recruited from a list of prior research participants at the San Francisco Department of Public Health to participate in daily EMA surveys on their substance use and sexual health behaviors for 1 week, followed by in-person focus groups (FGs). A total of 4 FGs explored the participants' experiences with the surveys, issues regarding privacy and confidentiality, and suggestions for improvement. Qualitative analysis was performed using content analysis. Descriptive statistics and Fisher exact tests were used to assess the associations between demographics or substance use behaviors and EMA completion.

RESULTS

Overall, 93.9% (295/314) of all delivered surveys were initiated, and of those, 98.0% (289/295) were completed. Neither participant demographics, including race (P=.65) or age (P=.43), nor substance use behaviors, including the frequency of alcohol (P=.40) or methamphetamine (P=.91) use or any cocaine (P=.28), crack (P=.99), or polysubstance use (P=.24), were found to be associated with survey completion. Overall, participants were receptive to the text message-based EMA surveys. Facilitators included survey timing, user-friendly survey design, survey-stimulated self-reflection, coding of sensitive phrases, and other privacy benefits of a mobile survey. Barriers included an inability to correct texting errors and participants' perception of judgment or stigmatization related to questions about condomless sex. To improve EMA compliance and uptake, participants suggested adding response confirmations, clarifying survey language, and continuing to diversify the study audience.

CONCLUSIONS

EMA appears to be feasible and acceptable among this sample of racial and ethnic minority SUMSM. Close attention to EMA study design and the development of nonjudgmental, contextualized questions regarding stigmatized health behaviors may be critical to further improve EMA compliance.

Sustained HIV viral suppression among men who have sex with men in the Miami-Dade County Ryan White Program: the effect of demographic, psychosocial, provider and neighborhood factors

Background

HIV viral suppression is associated with health benefits for people living with HIV and a decreased risk of HIV transmission to others. The objective was to identify demographic, psychosocial, provider and neighborhood factors associated with sustained viral suppression among gay, bisexual, and other men who have sex with men.

Methods

Data from adult men who have sex with men (MSM) enrolled in the Miami-Dade County Ryan White Program (RWP) before 2017 were used. Sustained viral suppression was defined as having an HIV viral load < 200 copies/ml in all viral load tests in 2017. Three-level (individual, medical case management site, and neighborhood) cross-classified mixed-effect models were used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for sustained viral suppression.

Results

Of 3386 MSM, 90.8% were racial/ethnic minorities, and 84.4% achieved sustained viral suppression. The odds of achieving sustained viral suppression was lower for 18–24 and 25–34 year-old MSM compared with 35–49 year-old MSM, and for non-Latino Black MSM compared with White MSM. Those not enrolled in the Affordable Care Act, and those with current AIDS symptoms and a history of AIDS had lower odds of achieving sustained viral suppression. Psychosocial factors significantly associated with lower odds of sustained viral suppression included drug/alcohol use, mental health symptoms, homelessness, and transportation to appointment needs. Individuals with an HIV physician who serves a larger volume of RWP clients had greater odds of sustained viral suppression. Neighborhood factors were not associated with sustained viral suppression.

Conclusion

Despite access to treatment, age and racial disparities in sustained viral suppression exist among MSM living with HIV. Addressing substance use, mental health, and social services’ needs may improve the ability of MSM to sustain viral suppression long-term. Furthermore, physician characteristics may be associated with HIV outcomes and should be explored further.

Does HIV Pre-Exposure Prophylaxis Modify the Effect of Partnership Characteristics on Condom Use? A Cross-Sectional Study of Sexual Partnerships Among Men Who Have Sex with Men in San Francisco, California

Increasing rates of sexually transmitted infections (STIs) in the United States among men who have sex with men (MSM) have raised concerns that pre-exposure prophylaxis (PrEP) has been associated with higher engagement in condomless anal intercourse (CAI). While partnership characteristics have previously been found to influence condom use, the extent to which PrEP use may modify their effect on CAI remains unknown. A secondary analysis of 535 sexual partnerships from a cross-sectional study in San Francisco was conducted to evaluate interactions between PrEP use and partnership characteristics on CAI. Bivariate and multivariate generalized estimating equation (GEE) logistic regression models were used to estimate relative measures of association, adjusted for confounding by seroconcordance and partnership type, as well as account for repeated partnerships per respondent. Partnerships where both partners used biomedical prevention had significantly greater odds of CAI [odds ratio (OR) = 5.19, 95% confidence interval (CI): 2.27-11.9] compared to those where only one partner used biomedical prevention, while those where neither partner used biomedical prevention had significantly lower odds of CAI (OR = 0.61, 95% CI: 0.40-0.93). There was no significant association between meeting place (online vs. offline) and sexual risk taking (OR = 1.03, p = 0.894). Having one partner disclose their HIV status (compared to neither partner having disclosed) was associated with significantly higher odds of CAI among partnerships of PrEP-using MSM [adjusted OR (aOR) = 5.28, 95% CI: 1.91-14.61], while the association was not significant among the partnerships of non-PrEP-using MSM (aOR = 1.29, 95% CI: 0.75-2.21). Differences in condom use among MSM using PrEP may not be well explained by differences in the effect of partnership characteristics. MSM using PrEP appear to commonly practice biomedical matching and high engagement in CAI with other biomedical prevention users, which could indicate relatively concentrated sexual networks and partly explain their disproportionate risk for STIs. Future studies should further investigate biomedical matching to develop interventions that further promote the sexual health of those using PrEP.

Acceptability of pharmacotherapy for hazardous alcohol use among men who have sex with men: Findings from a qualitative study

INTRODUCTION

Men who have sex with men (MSM) experience high rates of binge drinking, alcohol use disorder (AUD), and alcohol-related health issues. Pharmacotherapy for AUD can reduce hazardous drinking, yet remains underutilized among MSM. This qualitative study examined knowledge and perceptions regarding AUD medications among MSM, with an emphasis on naltrexone.

METHODS

Three focus group discussions (FGDs) with MSM who consumed alcohol in the past year were conducted in February 2015 (N = 39) in the San Francisco Bay Area. The FGD guide generated discussions about hazardous drinking, the social contexts of drinking, and alcohol reduction and cessation options, including pharmacotherapy. Interviews were analyzed via directed content analysis to codify themes.

RESULTS

For participants, drinking at LGBTQ bars was an important social activity. Many expressed interest in reducing alcohol use, but few had heard of pharmacotherapy for AUD. Potential uptake was limited by perceptions of disulfiram as the prototype medication, side effects associated with disulfiram, and concerns that medications do not address alcohol-related stigma or social drivers of drinking. Participants were more receptive to pharmacotherapy when presented with medication options that did not require abstinence. Participants reported being more likely to try pharmacotherapy as part of a peer group or treatment program.

CONCLUSIONS

Efforts to increase the knowledge and availability of naltrexone and harm reduction approaches, while addressing addiction- and medication-related stigma, might improve pharmacotherapy uptake for AUD and decrease hazardous drinking among MSM for whom alcohol holds social significance.
