Co-occurring psychiatric and drug use disorders among sexual minority men with lifetime alcohol use disorders

Prevalence, distribution, and inequitable co-occurrence of mental ill-health and substance use among gender and sexuality diverse young people in Australia: epidemiological findings from a population-based cohort study

PURPOSE

To estimate the prevalence, distribution, and co-occurrence of mental ill-health and substance use among gender and sexuality diverse young people relative to their cisgender and heterosexual peers in Australia using population-level, nationally representative data.

METHODS

We utilised Wave 8 (2018) data from the Longitudinal Study of Australian Children (N = 3037, Mage = 18.4) collected via an assessment protocol comprising interviews, direct observations, and assessments (on average 60 min per survey occasion). Weighted prevalence ratios and logistic regression models adjusted for demographic confounders were used to estimate the prevalence and distribution of mental ill-health (psychological distress, past 12-month self-harm thoughts and behaviours, past 12-month suicidal ideation, planning, attempt/s) and substance use outcomes (past 12-month cigarette, alcohol, and marijuana use) across gender identity (trans vs. cisgender), sexuality (gay/lesbian, bisexual, queer [those identifying with an 'other' sexuality identity that is not 'gay', 'lesbian', 'bisexual', or 'heterosexual'] vs. heterosexual) and sexuality diversity status (sexuality diverse vs heterosexual) subgroups. Sex-stratified prevalence rates and accompanying adjusted logistic regression models were also used to assess mental ill-health and substance use disparities by sexuality diversity status. Adjusted multinominal logistic regression models were used to test disparities in co-occurring outcomes by sexuality identity) sexuality status sub-groups, and Fisher's Exact Test of Independence for co-occurring disparities by gender identity (due to small sample size). All analyses used Wave 8 sample weights and adjusted for postcode-level clustering.

RESULTS

Among gender and sexuality diverse participants, 59 - 64% reported high or very high levels of psychological distress, 28 - 46% reported past 12-month self-harm ideation or attempts, and 26 - 46% reported past 12-month suicidal ideation, planning, or behaviour. We found significant disparities in high/very high levels of psychological distress, self-harm behaviours and suicidal behaviours among trans participants (adjusted odds ratios (aORs) ranged from 3.5 to 5.5) and sexuality diverse participants (aORs ranged from 3.5 to 3.9), compared with cisgender and heterosexual participants, respectively. Highest disparities in any past 12-month self-harm and suicidal behaviours appeared most pronounced among trans participants and queer participants compared with their cisgender, heterosexual counterparts. Minor differences by sex among sexuality diverse participants were observed for select mental ill-health outcomes. Sexuality diverse participants, and particularly sexuality diverse females, were significantly more likely to report past 12-month cigarette use and past 12-month marijuana use (adjusted odds ratio (aORs) ranging 1.4-1.6). Trans young people were at significantly elevated risk of mental ill-health in co-occurrence with cigarette and marijuana use compared with their cisgender peers (Fisher's Exact Test of Independence p < 0.05 for all), whereas sexuality diverse young people were at greater risk of co-occurring mental ill-health and cigarette co-use and marijuana co-use, compared with their non-sexuality diverse peers (adjusted multinomial odds ratios (aMORs) ranging 2.2-6.0).

CONCLUSION

Mental ill-health, substance use, and their co-occurrence disproportionately affects gender and sexuality diverse young people in Australia. Further research should study the longitudinal development of these disparities through adolescence, with close attention to the social, embodied contexts of substance use among LGBTQ + young people with the view to building LGBTQ + affirming models of harm reduction.

Problematic alcohol use among gay, bisexual, and other men who have sex with men in Canada: the role of proximal stressors and anxiety

BACKGROUND

Gay, bisexual, and other men who have sex with men (GBM) report high rates of problematic alcohol use, anxiety, and depression. This may, in part, be due to stressors related to their sexual identity (i.e., minority stressors). However, few studies have examined both distal and proximal stressors, as well as the specific psychological mechanisms by which these stressors may be related to alcohol use outcomes, in a representative sample of GBM. We explored the relationship between distal and proximal stressors and alcohol use outcomes, as well as the role of anxiety and depression as potential mediators of these relationships.

METHODS

We analyzed the baseline data of 2,449 GBM from Engage, a cohort study of sexually active GBM recruited using respondent-driven sampling (RDS) in Montreal, Toronto, and Vancouver from February 2017 to August 2019. Using structural equation modeling, we examined the associations between distal minority stressors (i.e., experiences of heterosexist harassment, rejection, and discrimination), proximal minority stressors (i.e., internalized homonegativity, concerns about acceptance, concealment, and lack of affirmation), anxiety and depression, and alcohol consumption and alcohol use problems. RDS-adjusted analyses controlled for age, income, sexual orientation, ethnicity, recruitment city, and HIV serostatus.

RESULTS

There were positive direct associations between distal stress and proximal stress, anxiety, and depression, but not alcohol use outcomes. Proximal stress had a positive direct association with anxiety, depression, and alcohol use problems, but not alcohol consumption. Anxiety was positively associated with alcohol consumption and alcohol use problems. Depression was negatively associated with alcohol consumption but not alcohol use problems. Regarding indirect effects, distal stress was associated with alcohol use outcomes via proximal stress and anxiety, but not via depression.

CONCLUSIONS

We found support for a minority stress model as it relates to alcohol use outcomes among GBM. Findings suggest that proximal minority stress and anxiety differentially impact the problematic alcohol use among GBM who experience heterosexist discrimination. Clinical providers should consider incorporating the treatment of proximal minority stressors and anxiety into existing alcohol interventions for GBM.

"I'm Gay With an Asterisk": How Intersecting Identities Influence LGBT Strengths

Research attributes health disparities between sexual minority (those whose sexual orientation and/or practices differ from society, [SM]) and heterosexual populations to social marginalization. LGBT strengths (e.g., resiliency derived from LGBT identity) may reduce the impact of social marginalization. However, it is unclear how LGBT strengths are impacted by SMs' other identities (e.g., racial/ethnic and/or gender). To address this knowledge gap, the present study examined data from the LGBT Stress/Strength project, a qualitative research study investigating minority stress and LGBT strengths in relation to drinking. Participants (N = 22) were self-identified SMs in the northeastern U.S. Transcripts from in-depth interviews were coded using thematic analysis. Participants reported social support from other SMs and empathy toward others were forms of LGBT strength. Sampled SMs assigned female at birth had more intergenerational friendships and relied more on social support than those assigned male at birth. In addition, Black, indigenous, and people of color (BIPOC) participants described social marginalization from within the LGBT community, which reduced their reliance on social support. Our results suggest that LGBT strengths are influenced by LGBT community members intersecting identities. More research can expand upon these results by investigating how the confluence of SMs identities and LGBT strengths impact health disparities.

Co-occurring mental health and drug use experiences among Black and Hispanic/Latino sexual and gender diverse individuals

Black and Hispanic/Latino sexual and gender diverse individuals disproportionately experience overlapping health disparities, such as drug use and elevated depressive symptoms, which are often driven by minority stressors. We sought to better understand the interaction between drug use and mental health, as it may be fruitful in developing effective interventions to address co-occurring health disparities. In a longitudinal, 5-wave sample of 300 Black and Hispanic/Latino sexual and gender diverse (SGD) individuals collected between March 2020 and March 2022, we found a within-person association between greater than average levels of psychological distress (depression and anxiety) and more frequent extra-medical use of cannabis, inhalants, methamphetamines, and opioids over the span of two years. These associations held after adjusting for the direct, within-person association of internalized homonegativity with drug use frequency. These results suggest that psychological distress explains at least some variance in drug use among Black and Hispanic/Latino SGD individuals. This highlights the importance of interventions that focus on mental health among Black and Hispanic/Latino SGD individuals who report drug use.

Factors associated with improvements in symptoms of anxiety and depression among gay, bisexual and other men who have sex with men (gbMSM) in Vancouver, Canada: A prospective cohort study

BACKGROUND

Depression and anxiety are commonly experienced among gay, bisexual and other men-who-have-sex-with-men (gbMSM). We explored factors associated with improvements in mental health symptoms among gbMSM with abnormal depression and anxiety scores over a period of four years, in Vancouver, Canada.

METHODS

Sexually active gbMSM ≥16 years of age were recruited using respondent-driven sampling from February 2012 to February 2015. Participants completed a computer-assisted questionnaire which included the Hospital Anxiety and Depression Scale (HADS), and psychometric scales to measure loneliness, self-esteem and social connectedness, every 6 months until July 2019. Generalized linear mixed models were used to assess factors associated with normal/borderline HADS scores (<11) following a previous abnormal score (≥11) for each of anxiety and depression subscales.

RESULTS

We recruited 694 participants, of whom 580 had at least one follow-up visit. Across all visits, 43.6 % of participants ever had abnormal anxiety scores and 16.2 % ever had abnormal depression scores. Among those with abnormal anxiety scores, 34.9 % of follow-up visits demonstrated reductions in anxiety scores. Among those with abnormal depression scores 51.0 % of follow-up visits demonstrated reductions in depression scores. Reductions in anxiety scores were associated with increased self-esteem, decreased loneliness and the number of gbMSM seen/spoken to in the previous month. Reductions in depression scores were associated with increased self-esteem, decreased loneliness and having a regular partner.

CONCLUSION

Improvements in mental health symptoms were frequently observed. Social connectedness was related with improved anxiety and depression symptoms. Interventions to improve social connectedness may help to improve mental health for gbMSM.

A Review of Disparities in Cannabis Use and Cannabis Use Disorder Affecting Sexual and Gender Minority Populations and Evidence for Contributing Factors

Purpose of Review

Sexual and gender minorities (SGM) appear to be at elevated risk for cannabis use (CU) and cannabis use disorder (CUD) compared to cisgender heterosexuals. However, risk factors remain understudied among SGM. This review aims to summarize evidence for disparities in CU and CUD affecting SGM and factors contributing to these disparities.

Recent Findings

We found strong evidence that sexual minorities are at elevated risk for CU and CUD is elevated for sexual minority women. Evidence supports a concurrent association between minority stress and CUD symptoms. There is robust support for coping motives as a mechanism linking minority stress to subsequent CU and CUD. Studies also point to CU norms and contexts as potential risk factors.

Summary

SGM are at high risk for CU and CUD, and minority stress, CU norms, and contextual factors are implicated. Additional research is needed on CU among gender minorities, prospective effects of risk factors, and interventions for SGM.

Recovery among sexual minorities in the united states population: Prevalence, characteristics, quality of life and functioning compared with heterosexual majority

BACKGROUND

Lesbian, gay, and bisexual individuals ("sexual minorities" [SMs]) are overrepresented among individuals suffering from alcohol and other drug (AOD) problems. However, little is known regarding differences, particularly in functioning and well-being, between SMs and heterosexuals in recovery from AOD problems.

METHOD

Cross-sectional, nationally representative sample of US adults who resolved an AOD problem (N = 2002; National Recovery Study [Kelly et al., 2017]). Univariate analyses tested for differences between SMs and heterosexuals on socio-demographic, AOD use/treatment and clinical/legal factors. Unadjusted regressions tested for group differences on indices of current functioning and well-being. Multivariable regressions investigated factors that differentiated groups to understand which might explain any observed group disparities in functioning and well-being. LOWESS analyses explored differences across time in recovery on functioning/well-being.

RESULTS

Prevalence of SMs in the US recovery population was 11.7% (n = 220). Compared with heterosexuals (88.3%, n = 1666), SMs had shorter time in recovery (OR=0.97; 95% CI: 0.96, 0.99); were less likely to be employed (OR=0.64; 95% CI: 0.43, 0.96); and more likely to have a co-occurring psychiatric disorder (OR=2.24; 95% CI: 1.49, 3.37), an arrest history (OR=1.61; 95% CI: 1.08, 2.39), and report opioids as primary substance (OR=2.50; 95% CI: 1.18, 5.28). Unadjusted models showed, compared to heterosexuals, SMs had significantly worse levels on all functioning and well-being outcomes. Adjusted models explained most differences, except for psychological distress.

CONCLUSION

SMs evince more problematic clinical/legal histories and face greater psychosocial challenges in recovery. Research is needed to understand the unique experiences of recovering SMs in order to better address observed functioning and well-being disparities.

Sexual orientation and gender identity disparities in co-occurring depressive symptoms and probable substance use disorders in a national cohort of young adults

This study examined sexual orientation and gender identity differences in co-occurring depressive symptoms and substance use disorders (SUDs) among young adults in the Growing Up Today Study national cohort (n = 12,347; ages 20-35; 93% non-Hispanic white). Self-administered questionnaires assessed recent co-occurring depressive symptoms and probable nicotine dependence, alcohol use disorder, and drug use disorder. Multinomial logistic regressions with generalized estimating equations quantified differences in prevalences of depressive symptoms only, SUDs only, and co-occurrence, among sexual minorities (mostly heterosexual; lesbian, gay, and bisexual [LGB]) compared to completely heterosexual participants, and gender minorities compared to cisgender participants. Analyses stratified by sex assigned at birth revealed sexual minorities evidenced greater odds of co-occurrence than their completely heterosexual counterparts (assigned female AORs: 3.11-9.80, ps < 0.0001; assigned male AORs: 2.90-4.87, ps < 0.001). Sexual orientation differences in co-occurrence were pronounced among LGB participants assigned female at birth who evidenced nearly 10 times the odds of co-occurring depressive symptoms with nicotine dependence and drug use disorders than did heterosexual participants assigned female at birth. Relationships between gender identity and co-occurrence were generally weaker, possibly due to low power. Gender minorities assigned male at birth, however, evidenced greater odds of co-occurring depressive symptoms and alcohol use disorders (AOR 2.75, p = 0.013) than their cisgender counterparts. This study adds to the limited research quantifying sexual orientation or gender identity differences in recent co-occurring depressive symptoms and SUDs among young adults and suggests sexual and gender minority young adults should be prioritized in prevention and treatment of co-occurring depression and SUDs.

Covariates of hazardous alcohol use among sexual and gender minorities in Texas: Identifying the most vulnerable

BACKGROUND

Information is limited on the prevalence of hazardous drinking and associated covariates among sexual and gender minority (SGM) persons. These analyses estimated the prevalence of hazardous drinking and identified associated covariates.

METHODS

A total of 1273 SGM adolescents and adults living in Texas completed an online survey between March 2016 and January 2017. Variables associated with hazardous drinking at the bivariate-level (p < 0.10) were entered into multiple logistic regression models to estimate the strength of their association.

RESULTS

More than a third (39.1%) of participants meet criteria for hazardous drinking. Compared to non-hazardous drinkers, hazardous drinkers were younger (x- = 20.7 [SD = 8.9] vs. x- = 26.5 [SD = 13.8]) and more likely to be Hispanic (41.5% vs. 26.2%). Hazardous drinkers were more likely to report using substances in past 12 months, including opioids (15.3% vs. 6.7%), stimulants (26.3% vs. 12.7%), and marijuana (37.6% vs. 21.2%). More hazardous drinkers reported injecting drugs (12.3% vs. 5.8%) and having a history of incarceration (14.1% vs. 7.3%). They were less likely to be diagnosed with depression (50.2% vs. 56.5%). When entered into a multivariate logistic regression model, hazardous drinkers were more likely to be younger (aOR = 0.97 [0.95, 0.98]), Hispanic (aOR = 1.5 [1.2, 2.0]), have a history of incarceration (aOR = 2.4 [1.5, 3.6]), and use a substance, not including marijuana (aOR = 1.7 [1.3, 2.3]). They were less likely to be diagnosed with depression (aOR = 0.73 [0.6, 0.9]).

CONCLUSIONS

Our findings highlight the intersection of race and ethnicity, mental health, criminal justice involvement, and substance use and the need for tailored interventions that address underlying determinants.

Sexual orientation and gender identity disparities in substance use disorders during young adulthood in a United States longitudinal cohort

BACKGROUND

This study examined associations of sexual orientation and gender identity with prevalence of substance use disorders (SUDs) and co-occurring multiple SUDs in the past 12-months during young adulthood in a United States longitudinal cohort.

METHODS

Questionnaires self-administered in 2010 and 2015 assessed probable past 12-month nicotine dependence, alcohol abuse and dependence, and drug abuse and dependence among 12,428 participants of an ongoing cohort study when they were ages 20-35 years. Binary or multinomial logistic regressions using generalized estimating equations were used to estimate differences by sexual orientation and gender identity in the odds of SUDs and multiple SUDs, stratified by sex assigned at birth.

RESULTS

Compared with completely heterosexuals (CH), sexual minority (SM; i.e., mostly heterosexual, bisexual, lesbian/gay) participants were generally more likely to have a SUD, including multiple SUDs. Among participants assigned female at birth, adjusted odds ratios (AORs) for SUDs comparing SMs to CHs ranged from 1.61 to 6.97 (ps<.05); among participants assigned male at birth, AORs ranged from 1.30 to 3.08, and were statistically significant for 62% of the estimates. Apart from elevated alcohol dependence among gender minority participants assigned male at birth compared with cisgender males (AOR: 2.30; p < .05), gender identity was not associated with prevalence of SUDs.

CONCLUSIONS

Sexual and gender minority (SGM) young adults disproportionately evidence SUDs, as well as co-occurring multiple SUDs. Findings related to gender identity and bisexuals assigned male at birth should be interpreted with caution due to small sample sizes. SUD prevention and treatment efforts should focus on SGM young adults.

Associations between sociodemographic characteristics and substance use disorder severity among methamphetamine-using men who have sex with men

Background: Men who have sex with men (MSM) have elevated rates of substance use disorders (SUDs) and differences across sociodemographic sub-groups of MSM are associated with a greater risk of deleterious outcomes. Although studies have shown that MSM report greater rates of polysubstance use relative to other adult populations, the associations between sociodemographic characteristics and both acute substance use and substance use severity among methamphetamine-using MSM are unknown. Objectives: The present study examines associations between sociodemographic characteristics and (a) recent substance use and (b) SUD severity. Method: From March 2014 to January 2016, 286 methamphetamine-using MSM were recruited to complete a baseline Audio Computer-Assisted Self-Interview (ACASI) assessment and the SCID MINI. Multivariable analyses employed generalized structural equation modeling given the non-continuous nature of the endogenous variables. Results: All measured sociodemographic characteristics except gay self-identification were significantly associated with recent substance use (all ps ≤ .05), and all characteristics except current homelessness were significantly associated with diagnostic SUD severity (all ps ≤ .05). However, nuanced risks were observed in participants' use of specific substances regarding recent substance use and substance use severity. Conclusion: These results suggest that multiple factors contribute to the risks of SUD severity among methamphetamine-using MSM. As such, these results are useful in the tailoring of clinical and psychosocial intervention strategies that serve this and other high-risk populations.

Internalized Homophobia and Drug Use in a National Cohort of Gay and Bisexual Men: Examining Depression, Sexual Anxiety, and Gay Community Attachment as Mediating Factors

The minority stress process of internalized homophobia (IH) has been associated with a range of adverse health outcomes among gay and bisexual men (GBM). However, evidence is mixed regarding the effect of IH on drug use, suggesting the potential role of multiple mediated pathways. Researchers have linked depression, sexual anxiety, and gay community attachment with IH. Depression, sexual anxiety, and gay community attachment have also been linked with drug use and drug-related problems suggesting potential mediating roles. A U.S. national sample of 1071 HIV-negative GBM completed at-home surveys, including measures of sociodemographic characteristics, IH, depression, sexual anxiety, gay community attachment, and drug use and associated problems. Adjusting for sociodemographic characteristics, depression mediated the association between IH and recent drug use. IH was positively associated with depression, and depression was positively associated with recent drug use. Gay community attachment partially mediated drug-related problems. IH had a positive direct association with drug-related problems and a negative direct association with gay community attachment. Gay community attachment had a positive association with drug-related problems. IH was positively associated with sexual anxiety, but sexual anxiety was not associated with either drug outcome. Efforts to reduce IH among HIV-negative GBM are likely to have a positive impact on mental health problems, as well as reduce risk for drug use and drug-related problems. Gay communities could provide the social support necessary for reducing IH; however, emphasis on community level interventions that address factors that increase risk for drug-related problems remains important.

Mental Health and Substance Use Disorder Comorbidity among Methamphetamine-Using Men Who have Sex with Men

Men who have sex with men (MSM) exhibit elevated rates of mental health and substance use disorder relative to their non-MSM male counterparts. Methamphetamine use in particular has been associated with both neuronal damage and mental health disorders among MSM, and this study reports on the prevalence and comorbidity of DSM-5 mental health and substance use disorders in a sample of methamphetamine-using MSM. From March 2014 through January 2015, 286 methamphetamine-using MSM enrolled in a study to reduce methamphetamine use and sexual risk behaviors. At baseline, participants demonstrated high rates of current major depressive episode (35.8%), antisocial personality disorder (23.9%), suicide risk (23.2%), obsessive-compulsive disorder (23.2%), and social phobia (20.4%), as well as methamphetamine use disorder (89.1%), marijuana use disorder (41.0%), alcohol use disorder (39.6%), cocaine use disorder (30.9%), and inhalants use disorder (15.4%). Analyses revealed significant (p < 0.05) associations between methamphetamine use disorder severity and all listed mental health disorders, as well as between alcohol use disorder and all listed mental health disorders. Mental health disorder prevalence and substance use disorder severity were both elevated, and both methamphetamine and alcohol use disorder severity were associated with increased likelihood of comorbid mental health disorder.

The role of perceptions of partner's alcohol use in heavy alcohol use and alcohol reduction intervention preferences among LGBQ adults in primary, romantic relationships

Correlates of heavy episodic alcohol and alcohol reduction intervention preferences were examined among LGBQ adults in romantic relationships. Anonymous data were collected online; analyses included logistic and multinomial regression models. One-fourth of participants reported recent heavy episodic alcohol use. Perceptions of partners' engaging in heavy alcohol use was associated with an incsreased odds of engaging in heavy alcohol use. Perceptions of partners' heavy alcohol use was associated an increased odds of preferring a couples-based alcohol intervention compared to preferring no intervention. Findings highlight the need to consider partners in alcohol interventions for LGBQ couples.

Feasibility of an Emotion Regulation Intervention to Improve Mental Health and Reduce HIV Transmission Risk Behaviors for HIV-Positive Gay and Bisexual Men with Sexual Compulsivity

Gay and bisexual men (GBM) report high rates of sexual compulsivity (SC), yet no empirically based treatments exist. An intervention based on the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders was pilot tested in a sample of 13 HIV-positive GBM with SC. Participants completed a baseline interview, and were offered up to ten intervention sessions. Of those, 11 completed a 3-month follow-up assessment. Despite problems with session attendance (only 4 men completed all 10 sessions), improvements were observed in all psychological outcomes, including SC, depression, and anxiety. Decreases were observed in drug use and HIV risk. The Unified Protocol may be useful in improving the health of HIV-positive GBM, however challenges with session attendance must be addressed. Future work should consider if fewer sessions produce similar results, whether barriers to attending all sessions could be alleviated, and how the intervention would perform compared to treatments.

Prevalence, sociodemographic correlates and DSM-5 substance use disorders and other psychiatric disorders among sexual minorities in the United States

PURPOSE

The purpose of this study was to present current nationally representative data on the prevalences, sociodemographic correlates and risk of DSM-5 substance use disorders and other psychiatric disorders among sexual minorities (SMs) relative to heterosexuals, and among SMs by gender.

METHODS

Data were derived from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III.

RESULTS

In the general noninstitutionalized population, 1.5%, 1.3% and 0.5% of individuals self-identified as gay/lesbian, bisexual and not sure sexual orientations. Men were more likely to report gay/lesbian orientation than women (1.8% vs. 1.2%). Women were more likely than men to report bisexual (1.8% vs. 0.8%) and not sure (0.6% vs. 0.4%) sexual orientations. Sociodemographic characteristics varied across sexual orientation and gender. Relative to heterosexuals, disparities in substance use and psychiatric disorders were found across sexual orientations, especially among bisexual women. Greater rates of specific psychiatric disorders were also demonstrated by women reporting bisexual and not sure orientations relative to lesbian women, with fewer differences in rates of psychopathology among SM men.

CONCLUSIONS

Despite growing acceptance of SMs and SM rights over the past decade, substantial mental health disparities exist among these subgroups of the U.S. noninstitutionalized population, especially among bisexual women. More research is needed to understand these mental health disparities, while considering nuances of multiple intersecting minority identities and unique contextual factors.

FINDINGS

underscore the importance of advancing future population-based research that includes detailed information on the health and well-being of SMs in the United States.

Identifying HIV care enrollees at-risk for cannabis use disorder

Increased scientific attention given to cannabis in the United States has particular relevance for its domestic HIV care population, given that evidence exists for both cannabis as a therapeutic agent and cannabis use disorder (CUD) as a barrier to antiretroviral medication adherence. It is critical to identify relative risk for CUD among demographic subgroups of HIV patients, as this will inform detection and intervention efforts. A Center For AIDS Research Network of Integrated Clinical Systems cohort (N = 10,652) of HIV-positive adults linked to care at seven United State sites was examined for this purpose. Based on a patient-report instrument with validated diagnostic threshold for CUD, the prevalence of recent cannabis use and corresponding conditional probabilities for CUD were calculated for the aggregate sample and demographic subgroups. Generalized estimating equations then tested models directly examining patient demographic indices as predictors of CUD, while controlling for history and geography. Conditional probability of CUD among cannabis-using patients was 49%, with the highest conditional probabilities among demographic subgroups of young adults and those with non-specified sexual orientation (67-69%) and the lowest conditional probability among females and those 50+ years of age (42% apiece). Similarly, youthful age and male gender emerged as robust multivariate model predictors of CUD. In the context of increasingly lenient policies for use of cannabis as a therapeutic agent for chronic conditions like HIV/AIDS, current study findings offer needed direction in terms of specifying targeted patient groups in HIV care on whom resources for enhanced surveillance and intervention efforts will be most impactful.

Sexual Behaviors Linked to Drug and Alcohol Use Among Men Who Have Sex With Men in China

BACKGROUND

High-risk sexual behaviors drive the HIV epidemic among men who have sex with men (MSM). Alcohol consumption and use of club drugs may increase sexual risk behaviors. We evaluated effects of drug and alcohol use on sexual behaviors with both their male and female partners as well as on HIV and syphilis infections among MSM in China.

METHODS

As the part of a community randomized clinical trial that conducted among MSM in Beijing from 2013 to 2015, we recruited a total of 3,680 participants cross-sectionally. A self-administered questionnaire was employed to collect information regarding demographics, sexual behaviors, and a history of alcohol and drug use. Blood sample was collected for HIV and syphilis testing.

RESULTS

A total of 3,588 MSM completed the survey and were included in the data analysis. The mean age was 29.9 with 97.3% of Han-ethnicity and 85.0% unmarried. The HIV and syphilis prevalence was 12.7% and 7.4%, respectively. Drug use was significantly associated with higher odds of HIV infection (aOR = 1.3, 95% Confidence Interval [CI] = 1.0,1.6), but not associated with syphilis. A higher level of alcohol consumption was similarly associated with higher odds of HIV risks with both male (e.g., condomless sex acts) and female partners (e.g., numbers of sexual partners).

CONCLUSION

The association between drug and alcohol use and high-risk behaviors is notable among MSM in China. Integrated HIV interventions that target substance use among MSM may be more effective than programs that only target HIV alone.

Mental health disorders among homeless, substance-dependent men who have sex with men

INTRODUCTION AND AIMS

Homelessness is associated with increased prevalence of mental health disorders, substance use disorders and mental health/substance use disorder comorbidity in the United States of America. Gay, bisexual and other men who have sex with men (MSM) living in the United States are at increased risk for homelessness, and have also evidenced elevated mental health and substance use disorder prevalence relative to their non-MSM male counterparts.

DESIGN AND METHODS

Secondary analysis of data from a randomised controlled trial estimating the diagnostic prevalence of substance use/mental health disorder comorbidity among a sample of homeless, substance-dependent MSM (DSM-IV verified; n = 131).

RESULTS

The most prevalent substance use/mental health disorder comorbidities were stimulant dependence comorbid with at least one depressive disorder (28%), alcohol dependence comorbid with at least one depressive disorder (26%) and stimulant dependence comorbid with antisocial personality disorder (25%).

DISCUSSION AND CONCLUSIONS

Diagnostic depression and antisocial personality disorder both demonstrated high rates of prevalence among homeless, substance-dependent (particularly stimulant and alcohol dependent) MSM.
