High prevalence of multiple syndemic conditions associated with sexual risk behavior and HIV infection among a large sample of Spanish- and Portuguese-speaking men who have sex with men in Latin America

Longitudinal Analysis of Overlapping Psychosocial Factors Predicting Incident Hospitalization Among Mixed HIV Serostatus Men who have Sex with Men in the Multicenter AIDS Cohort Study

Men who have sex with men (MSM) are at increased risk for certain types of chronic diseases and mental health problems. Despite having extended survival in the highly active antiretroviral therapy (HAART) era, MSM living with HIV contend with aging-related diseases and complications with treatment. Consequent hospitalizations incur high costs, fear, low quality of life, and frailty. Unlike heterosexual men, MSM experience more structural violence and "syndemics" of psychosocial factors that not only accelerate HIV acquisition and transmission risk but also may increase morbidity, leading to greater rates of hospitalization. We aim to examine the impact of "syndemic" psychosocial factors on the incidence of hospitalization among geographically diverse MSM in the US. Participants were 1760 MSM from the Multicenter AIDS Cohort Study (MACS) between 2004 and 2019. We examined the relationship between six psychosocial factors (depression, stimulant use, smoking, heroin use, childhood sexual abuse, and intimate partner violence) and incident hospitalization (admission to a hospital for treatment). We found a positive dose-response relationship between the number of syndemic factors and hospitalization. MSM reporting five or more syndemic factors had over twice the risk of hospitalization compared to MSM without syndemic factors [aRR = 2.14 (95% CI = 1.56, 2.94)]. Psychosocial factors synergistically increased hospitalizations over time. The positive dose-response relationship between the number of syndemic factors and hospitalization and the synergistic effects of these factors underscore the need for interventions that disentangle the syndemics to reduce hospitalization and related costs and improve the quality of life among MSM.

A Scoping Review of Biobehavioural Interventions to Improve PrEP Continuum of Care in Latin America

According to the literature, biobehavioural interventions or combined strategies would reduce the risk of HIV infection by more than 7,000 new cases each day, which would contribute to the battle facing Latin America, where despite the high incidence and prevalence of HIV in the region, access to PrEP (pre-exposure prophylaxis) is very limited. The objective of this research was, consistent with the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), to conduct a scoping review to assess the evidence of available outcome data on biobehavioural interventions and programs to address gaps in the PrEP continuum of care in Latin America. The search was conducted in the databases EBSCOhost, WoS, Scopus, and ProQuest, and include all studies published from 2010 to 2021. One hundred eighty-six studies were identified and evaluated according to the eligibility criteria in six stages starting with the elimination of duplicates until the selection of studies that met the previously mentioned criteria; at the end five studies were chosen which were submitted to the methodological quality assessment including compliance with ethical guidelines. Results show that biobehavioural interventions promoting PrEP in Latin America are effective in increasing condom use, decreasing HIV risk, and increasing PrEP awareness, uptake, adherence, and retention. The limited number of interventions in the PrEP continuum of care indicates a need for the uptake of dissemination and implementation science (D&I) frameworks. D&I could help facilitate the translation of evidence-based practices, interventions, and policies to address the HIV crisis in Latin America.

Syndemic Profiles and Sexual Health Risks Among Sexually Exploited Adolescent Girls in Taiwan: A Latent Class Analysis

Sexually exploited adolescent girls are disproportionately affected by adverse psychosocial conditions, such as intra-familial child physical and sexual abuse, extra-familial violence and sexual assault, alcohol and drug use, and suicide. Syndemic theory suggests that these adverse psychosocial or syndemic conditions are concentrated and co-occurring in socially marginalized populations, including sexually exploited adolescents, and increase their sexual health risks, including pregnancy, abortion, and the acquisition of sexually transmitted diseases (STDs). To examine clusters of syndemic conditions, latent class analysis (LCA) was conducted to classify 335 sexually exploited girls in Taiwan into subgroups based on their probability of experiencing each syndemic condition. We used syndemic class membership to predict their sexual health outcomes, specifically pregnancy, abortion, and the acquisition of STDs. The results of LCA revealed three classes, which were "low-risk syndemic," "moderate-risk syndemic," and "high-risk syndemic." The risk of acquisition of STDs among sexually exploited girls in the "high-risk syndemic class" and "moderate-risk syndemic class" was 239% and 135% higher, respectively, than the risk of acquisition of STDs among sexually exploited girls in the "low-risk syndemic class." Differences between these three classes in pregnancy and abortion were not significant. Our findings support the syndemic theory that a pattern of syndemic conditions is associated with an increased risk of acquiring STDs. Interventions aimed at reducing the acquisition of STDs among sexually exploited girls in Taiwan should adopt a comprehensive approach to address co-occurring conditions.

The Relationship Between Alcohol and Drug Use, Compulsive Sexual Behavior, and Condomless Anal Sex in Men Who have Sex with Men: Analysis of Retrospectively-Reported Sexual Behavior

Men who have sex with men (MSM) are disproportionately impacted by HIV in the United States, and substance use and compulsive sexual behavior (CSB) are contributors to HIV risk behavior. This study sought to examine the direct and interactive effects of concurrent substance use and CSB on condomless anal sex (CAS) in a community sample of MSM (N = 200) utilizing a 90-day timeline follow-back assessment. Results indicated CSB did not directly increase risk for CAS when controlling for substance use and age. There was limited evidence for a direct effect of concurrent alcohol use on CAS, and no evidence for an interaction effect with CSB. The relationship between concurrent drug use and CAS was moderated by CSB, such that concurrent drug use was positively associated with CAS for those who screened positive for CSB, while the association was non-significant for those who screened negative. Implications and limitations of these findings are discussed.

A nomogram of suicidal ideation among men who have sex with men in China: Based on the integrated motivational-volitional model of suicidal behavior

Introduction

Men who have sex with men (MSM) are a high-risk group for suicide, with a much higher prevalence of suicidal ideation (SI) than the general population and male population. The aim of this study was to explore the risk factors influencing the development of SI and to develop and validate a nomogram among MSM.

Methods

A cross-sectional study was conducted in 915 MSM from Shanghai, Shenyang, Shenzhen and Kunming, China using the snowball sampling method. The integrated motivational-volitional (IMV) model of suicidal behavior was used as a theoretical framework to collect different potential influencing factors of SI including diathesis-environment-life events factors and psychosocial factors. The risk factors of SI were screened by logistic regression analysis, and a nomogram for predicting SI were developed. Model properties including discrimination, calibration and decision curves were evaluated to validate the prediction model.

Results

882 MSM were included in the statistical analysis, with a lifetime prevalence of SI of 34.4% (303/882). Logistic regression analysis showed that age group, sexual orientation disclosure, high-risk sexual behavior, entrapment, defeat and interpersonal needs were associated with SI. A nomogram was constructed based on the above six predictors. AUC values of ROC for prediction model were 0.761 (0.641-0.770) and 0.754 (0.565-0.822) in the training set (n = 662) and validation set (n = 220), respectively. And there was no statistical difference of the AUC values between the two sets (P > 0.05). The calibration plots of the prediction model in both sets fit well with the ideal model (P > 0.05). The decision curves demonstrated that the threshold probability of prediction model in training set was 1-85%, whereas in validation set was 1-63%.

Conclusions

The lifetime prevalence of SI among Chinese MSM is high. The nomogram can serve as a useful tool to predict the development of SI among MSM. Defeat, entrapment and interpersonal needs, as significant predictors of SI, can be measured to identify SI in advance. Early assessment of SI and the enhancement of psychosocial interventions are important to prevent suicide-related behaviors. Future studies could incorporate more variables of interest to refine the prediction model to better guide behavioral and psychological intervention strategies among MSM.

Latin American Internet Survey for Men who have Sex with Men (LAMIS-2018): Design, methods and implementation

Despite men-who-have-sex-with-men (MSM) from Latin America (LA) are still a vulnerable population for known health-related conditions and social problems, availability of comparable data across LA countries for assessment and monitoring purposes is limited. The objective of this article is to present the study design and the questionnaire of LAMIS-2018 (Latin America MSM Internet Survey), its recruitment strategy, rates and sources by country, and the lessons learned from its implementation. LAMIS-2018 was a cross-sectional, internet-based survey targeting MSM living in 18 LA countries (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname, Uruguay, and Venezuela) that gathered data about sexual behaviors, HIV/STI and viral hepatitis knowledge, prophylactic use of antiretrovirals, psychosocial health, and access to sexual health services. The survey went online for four months and was available in three languages (Spanish, Portuguese, and Dutch). Promotion was carried out using dating apps, websites, social networks, and by community-based and academic organizations of each participating country directly in gay venues and in their own premises. Overall, 64,655 MSM participated in LAMIS-2018. Dating apps and websites were the most important recruitment source in most countries, except for Honduras, Nicaragua, and Suriname, where community-based organizations recruited most of the participants. Beyond the LAMIS-2018 implementation description, we highlight the feasibility of such a study in this context, based on the collaboration between community-based and academic organizations to obtain a large sample of MSM in the region. LAMIS-2018 data will contribute to identify determinants of risk behaviors and prevention needs of vulnerable MSM populations in each country of the region.

Health characteristics associated with chemsex among men who have sex with men: Results from a cross-sectional clinic survey in Norway

BACKGROUND

Chemsex typically involves drugs such as GHB/GBL, crystal meth and mephedrone, and is increasingly common among MSM. The behaviour has been found to be associated with sexually transmitted infections (STIs) and mental health problems. We aimed to assess the extent of chemsex engagement and associations with different aspects of health, among MSM attending a free specialist walk-in clinic for STIs in Oslo, Norway.

METHODS

Anonymous cross-sectional survey data was collected from June to October 2016. Differences in STI health (chlamydia, gonorrhoea, syphilis, HIV diagnoses), mental health (depression/anxiety) and internalised homonegativity between MSM using and not using GHB/GBL, crystal meth, mephedrone, cocaine or ketamine with sex in the last year were assessed descriptively and in a multivariate logistic regression model. The predictors were number of self-reported chlamydia, gonorrhoea or syphilis diagnoses, HIV diagnosis, depression/anxiety, and degree of internalised homonegativity. We adjusted for age, education level and having lived abroad.

RESULTS

Of the 518 MSM respondents, 17% reported sexualised use of either GHB/GBL, crystal meth, mephedrone, cocaine or ketamine in the last year (chemsex). We found significant positive associations between chemsex and self-reported HIV diagnoses (adjusted odds ratio [aOR] = 3.26, 95%CI = 1.37-7.76), number of reported chlamydia, gonorrhoea or syphilis diagnoses in the last year (aOR = 1.63, 95%CI = 1.18-2.12), having lived more than one year abroad (aOR = 2.10, 95%CI = 1.20-3.65), but no significant association with depression/anxiety (aOR = 1.02, 95%CI = 0.53-1.93), nor internalised homonegativity (aOR = 0.62, 95%CI = 0.33-1.19).

CONCLUSION

Chemsex engagement in Norway is relatively low compared to findings from STI clinics in other European countries, and GHB/GBL and cocaine the two most commonly used drugs with sex. Chemsex was more common among MSM having lived more than one year abroad, reporting HIV diagnoses and a higher number of either chlamydia, gonorrhoea or syphilis diagnoses in the last year. Health care providers need to be made aware of chemsex as a behavioural phenomenon among MSM, and special care should be afforded to MSM living with HIV and being diagnosed with STIs.

Factors Associated with Unprotected Anal Sex among Men Who Have Sex with Men in Mexico

The global prevalence of HIV is notably higher in men who have sex with men (MSM) compared with other male populations. Unprotected anal intercourse is the riskiest sexual behavior for HIV acquisition and/or transmission among this minority population. The purpose of the study was to identify if the syndemic of psychosocial stressors and experienced stigma are predictors of unprotected anal sex in Mexican MSM. A cross-sectional analytic study was carried out. It included adults residing in Manzanillo, Mexico, with oral/anal sex practices within the last year. Informed consent was given by 142 participants selected using snowball sampling. Collected data included sociodemographic characteristics, psychosocial stressors, experienced stigma, HIV knowledge, knowing a friend/acquaintance living with HIV/AIDS, and sexual risk behaviors. Adjusted logistic regression was used to identify predictors of unprotected anal sex within the last six months. Presence of syndemic of psychosocial stressors, drug use during sex, having friends/acquaintances with HIV/AIDS, and experiencing high stigma were positively associated; high level of HIV knowledge was negatively linked. Reducing psychosocial stressors and integrating stigma-mitigation strategies are key elements to reduce HIV transmission.

A Relational Framework for Engaging Latino Sexual Minority Men in Sexual and Behavioral Health Research

Latino sexual minority men (LSMM) experience sexual and behavioral health disparities. Yet, LSMM are underrepresented in sexual and behavioral health research, creating scientific inequity. There is, therefore, a need to identify the barriers and facilitators to LSMM's participation in sexual and behavioral health research, which is the gap that the current study sought to fill. We interviewed LSMM (n = 28; age 18-40, 57% US born) and key informants (n = 10) regarding LSMM's barriers and facilitators to participating in sexual and behavioral health research and suggestions for increasing participation. The research team coded the data via thematic analysis. We found that relational factors are central to understanding LSMM's participation in sexual and behavioral health research. Some relational experiences (e.g., interpersonal stigma) interfered with participation, whereas others (e.g., altruistic desires to contribute to community well-being) facilitated participation. The findings are consolidated within a new relational framework for understanding LSMM's participation in sexual and behavioral health research. Study findings highlight the centrality of relational factors in influencing LSMM's participation in sexual and behavioral health research. Relational factors can be used to inform the development of culturally relevant recruitment strategies to improve representation of LSMM in sexual and behavioral health research. Implementing these recommendations may address scientific inequity, whereby LSMM are disproportionately impacted by sexual and behavioral health concerns yet underrepresented in related research.

Intimate Partner Violence Victimization and Mental Health Among Men Who Have Sex With Men Living With HIV in Guatemala

Gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by poor mental health compared to their heterosexual counterparts. One factor that may increase mental health problems among MSM is intimate partner violence (IPV) victimization. The objectives of this study are to (a) describe the prevalence of different forms of IPV victimization experienced by MSM living with HIV in Guatemala City and (b) examine the relationship between IPV victimization and mental health. We analyzed cross-sectional survey data from a cohort of MSM living with HIV in Guatemala City (n = 374) to describe the burden of IPV, including physical, sexual, and emotional IPV. We then examined relationships between lifetime IPV and each form of recent IPV (past 12 months) with self-reported anxiety and depression using multivariable logistic regression. Over a quarter (27.3%) of the participants screened positive for anxiety and nearly one fifth (17.9%) screened positive for depression. Over a quarter of the participants (28.6%) reported ever having experienced any IPV victimization and 8.8% reported having experienced any form of recent IPV. In multivariable analyses, participants who experienced any form of lifetime IPV had roughly twice the odds of experiencing anxiety (OR: 1.86; 95% CI = [1.03, 3.38]) and depression (OR: 2.02; 95% CI = [1.02, 3.99]) compared to those who had not. Participants who experienced recent emotional IPV had over seven times the odds of experiencing anxiety (OR: 7.23; 95% CI = [1.46, 38.85]) compared to those who had not. MSM living with HIV in Guatemala experience a high burden of anxiety, depression, and IPV victimization. Those participants who had experienced lifetime IPV and recent emotional IPV were significantly more likely to screen for anxiety and depression. To improve their mental health, HIV clinics and other health services should provide support for MSM who have experienced IPV victimization.

Estimated Prevalence and Demographic Correlates of Compulsive Sexual Behavior Among Gay Men in the United States

BACKGROUND

Compulsive sexual behavior (CSB) is a clinical syndrome that causes significant distress and impairment for many individuals in the United States. Gay men are thought to have a higher prevalence of CSB, and it is associated with many relevant health outcomes including HIV risk behavior.

AIM

To estimate the prevalence and examine demographic correlates of CSB among gay men in the United States.

METHODS

A U.S. national probability sample of 227 gay-identified men were collected as part of the 2015 National Survey of Sexual Health and Behavior (NSSHB).

OUTCOMES

Participants completed the Compulsive Sexual Behavior Inventory (CSBI-13) and demographic measures.

RESULTS

Eighteen participants (7.93%) scored above the CSBI-13 clinical cut point, indicating they would likely meet criteria for clinically significant compulsive sexual behavior. To assess demographic correlates of CSB, demographic variables were entered into a logistic regression. Results of the logistic regression indicated that participant age, education, and religious affiliation were significant predictors of CSB status. Individuals scoring above the cut point were younger on average (M = 39.17; SD = 14.84) than those scoring below the cut point (M = 47.52; SD = 14.62; P = .02). Odds of scoring above the cut point were about six times greater for religiously affiliated participants compared to non-religiously affiliated participants (P = .005), and four times greater for those who had attended college compared to those who had not (P = .03).

CLINICAL IMPLICATIONS

These results indicate the prevalence of CSB in gay men is more modest than previously estimated, and is similar to the general population prevalence estimated in a previous study. The strongest predictor of CSB in this sample was religious affiliation, which underscores the importance of evaluating the role of religiosity in the etiology and/or identification of this clinical syndrome.

STRENGTHS AND LIMITATIONS

These findings are strengthened by the national probability sampling methodology and the use of the empirically validated CSBI-13 cut point. However, this sample was also older and had higher income and educational attainment than the larger population of gay men in the U.S.

CONCLUSION

These results indicate gay men may have a CSB prevalence rate similar to the general population, which contradicts previous research suggesting they are at greater risk for CSB.

Syndemics and preexposure prophylaxis are independently associated with rectal immune dysregulation in sexual minority men

OBJECTIVE

Syndemic conditions have been linked to engagement in receptive condomless anal sex (CAS) and HIV seroconversion. However, little is known about the biological pathways whereby syndemics could amplify vulnerability to HIV and other sexually transmitted infections (STIs).

DESIGN

HIV-negative sexual minority men (i.e. gay, bisexual and other MSM) were recruited from four STI clinics in South Florida for a cross-sectional study.

METHODS

Participants completed assessments for four syndemic conditions: depression, posttraumatic stress disorder, hazardous alcohol use and any stimulant use (i.e. any self-reported use or reactive urine toxicology results). Cytokine and chemokine levels were measured using LEGENDplex from the rectal swabs of 92 participants reporting receptive CAS and no antibiotic use in the past three months.

RESULTS

After controlling for age, race/ethnicity, preexposure prophylaxis (PrEP) use and number of receptive CAS partners, a greater number of syndemic conditions was associated with higher levels of rectal cytokines/chemokines relevant to immune activation, inflammation and the expansion and maintenance of T-helper 17 target cells, including rectal interferon-gamma (β = 0.22; P = 0.047), CXCL-8 (β = 0.24; P = 0.025) and interleukin-23 (β = 0.22; P = 0.049). Elevations in rectal cytokine or chemokine levels were most pronounced among participants experiencing two or more syndemic conditions compared with those experiencing no syndemic conditions. PrEP use was independently associated with elevations in multiple rectal cytokines/chemokines.

CONCLUSION

Syndemic conditions could increase biological vulnerability to HIV and other STIs in sexual minority men by potentiating rectal immune dysregulation.

Who Aren't We Reaching? Young Sexual Minority Men's Non-participation in an HIV-Prevention and Mental Health Clinical Trial

Despite many successful clinical trials to test HIV-prevention interventions for sexual minority men (SMM), not all SMM are reached by these trials. Identifying factors associated with non-participation in these trials could help to ensure the benefits of research extend to all SMM. Prospective participants in New York City and Miami were screened to determine eligibility for a baseline assessment for a mental health/HIV-prevention trial (N = 633 eligible on screen). Logistic regression and classification and regression tree (CART) analysis identified predictors of non-participation in the baseline, among those who were screened as eligible and invited to participate. Individuals who reported unknown HIV status were more likely to be non-participators than those who reported being HIV-negative (OR = 2.39; 95% CI 1.41, 4.04). In New York City, Latinx SMM were more likely to be non-participators than non-Latinx white SMM (OR = 1.81; 95% CI, 1.09, 2.98). A CART model pruned two predictors of non-participation: knowledge of HIV status and age, such that SMM with unknown HIV status and SMM ages 18-19 were less likely to participate. Young SMM who did not know their HIV status, and thus are more likely to acquire and transmit HIV, were less likely to participate. Additionally, younger SMM (18-19 years) and Latinx SMM in New York City were less likely to participate. The findings suggest the importance of tailored recruitment to ensure HIV-prevention/mental health trials reach all SMM.

Longitudinal Associations of Syndemic Conditions with Antiretroviral Therapy Adherence and HIV Viral Suppression Among HIV-Infected Patients in Primary Care

Psychosocial syndemic conditions have received more attention regarding their deleterious effects on HIV acquisition risk than for their potential impact on HIV treatment and viral suppression. To examine syndemic conditions' impact on the HIV care continuum, we analyzed data collected from people living with HIV (N = 14,261) receiving care through The Centers for AIDS Research Network of Integrated Clinical Systems at seven sites from 2007 to 2017 who provided patient-reported outcomes ∼4-6 months apart. Syndemic condition count (depression, anxiety, substance use, and hazardous drinking), sexual risk group, and time in care were modeled to predict antiretroviral therapy (ART) adherence and viral suppression (HIV RNA <400 copies/mL) using multilevel logistic regression. Comparing patients with each other, odds of ART adherence were 61.6% lower per between-patient syndemic condition [adjusted odds ratio (AOR) = 0.384; 95% confidence interval (CI), 0.362-0.408]; comparing patients with themselves, odds of ART adherence were 36.4% lower per within-patient syndemic condition (AOR = 0.636 95% CI, 0.606-0.667). Odds of viral suppression were 29.3% lower per between-patient syndemic condition (AOR = 0.707; 95% CI, 0.644-0.778) and 27.7% lower per within-patient syndemic condition (AOR = 0.723; 95% CI, 0.671-0.780). Controlling for the effects of adherence (AOR = 5.522; 95% CI, 4.67-6.53), each additional clinic visit was associated with 1.296 times higher odds of viral suppression (AOR = 1.296; 95% CI, 1.22-1.38), but syndemic conditions were not significant. Deploying effective interventions within clinics to identify and treat syndemic conditions and bolster ART adherence and continued engagement in care can help control the HIV epidemic, even within academic medical settings in the era of increasingly potent ART.

Strengthening resilience to reduce HIV risk in Indian MSM: a multicity, randomised, clinical efficacy trial

BACKGROUND

Men who have sex with men (MSM) in India are extremely marginalised and stigmatised, and therefore experience immense psychosocial stress. As current HIV prevention interventions in India do not address mental health or resilience to these stressors, we aimed to evaluate a resilience-based psychosocial intervention in the context of HIV and sexually transmitted infection (STI) prevention.

METHODS

We did a multicity, randomised, clinical efficacy trial in Chennai (governmental tuberculosis research institute) and Mumbai (non-governmental organisation for MSM), India. Inclusion criteria were MSM, aged 18 years or older, who were at risk of HIV acquisition or transmission, defined as having any of the following in the 4 months before screening: anal sex with four or more male partners (protected or unprotected), diagnosis of an STI, history of transactional sex activity, or condomless anal sex with a man who was of unknown HIV status or serodiscordant. Participants were required to speak English, Tamil (in Chennai), or Hindi (in Mumbai) fluently. Eligible individuals were randomly assigned (1:1) to either a resilience-based psychosocial HIV prevention intervention, consisting of group (four sessions) and individual (six sessions) counselling alongside HIV and STI voluntary counselling and testing, or a standard-of-care control comprising voluntary counselling and testing alone. The primary outcomes were number of condomless anal sex acts with male partners during the past month (at baseline and 4 months, 8 months, and 12 months after randomisation), and incident bacterial STIs (at 12 months after randomisation). Resilience-related mediators included self-esteem, self-acceptance, and depression. Recruitment is now closed. This trial is registered with ClinicalTrials.gov, NCT02556294.

FINDINGS

Between Sept 4, 2015, and June 28, 2018, we enrolled 608 participants; 305 (50%) were assigned to the psychosocial intervention condition and 303 (50%) were assigned to the control condition. 510 (84%) of 608 men completed an assessment at 4 months after randomisation, 483 (79%) at 8 months, and 515 (85%) at 12 months. 512 (99%) of 515 men had STI data from the 12-month assessment. The intervention condition had a 56% larger reduction in condomless anal sex acts (95% CI 35-71; p<0·0001) from baseline to 4-month follow-up, 72% larger reduction (56-82; p<0·0001) from baseline to 8-month follow-up, and 72% larger reduction (53-83; p<0·0001) from baseline to 12-month follow-up, compared with the standard-of-care control condition (condition by time interaction; χ2=40·29, 3 df; p<0·0001). Improvements in self-esteem and depressive symptoms both mediated 9% of the intervention effect on condomless anal sex acts. Bacterial STI incidence did not differ between study conditions at 12-month follow-up.

INTERPRETATION

A resilience-based psychosocial intervention for MSM at risk of HIV acquisition or transmission in India was efficacious in reducing condomless anal sex acts, with evidence for mediation effects in two key target resilience variables. HIV prevention programmes for MSM in India should address mental health resilience to augment reductions in the risk of sexually transmitted HIV.

Substance Use, Mental Health Problems, and Physical and Sexual Violence Additively Increase HIV Risk Between Male Sex Workers and Their Male Clients in Northeastern United States

BACKGROUND

Male sex workers (MSW) are disproportionately affected by HIV/AIDS, with an estimated HIV prevalence in the United States of 19.3%. Existing research suggests that MSW are also at risk of adverse psychosocial problems. Cross-sectional studies of MSW have suggested that co-occurring epidemics or a "syndemic" of psychosocial problems may increase vulnerability to HIV acquisition/transmission by elevated sexual risk. To the best of our knowledge, there are no published studies examining this relationship longitudinally among MSW. This study examined how a syndemic of 6 psychosocial problems result in additive risk for condomless anal sex (CAS) with male clients among a multicity, longitudinal cohort of MSW.

SETTING

Community-based organization and health center in 2 Northeastern US cities.

METHODS

Between 2015 and 2017, 100 MSW from Boston, MA and Providence, RI completed behavioral/psychosocial surveys at baseline, 6 months, and 12months. Generalized estimating equation modeling was used to examine the prospective relationship of additive psychosocial problems and subsequent CAS with male clients, adjusting for age, site, race/ethnicity, MSW-type, and HIV serostatus.

RESULTS

Mean age = 34.7 (SD = 11.8); 62% racial/ethnic minority; and 20% HIV+. The prevalence of 6 psychosocial syndemic problems was substantial at baseline and remained high at each time point (all within the past 6 months): 74% problematic depressive symptoms, 27% polydrug use (3+ drugs, not including stimulants), 57% stimulant (methamphetamine/cocaine/crack) use, 44% hazardous drinking, 15% experienced client-specific physical/sexual violence, and 57% childhood sexual abuse. Looking at the number of psychosocial problems experienced, 7% had zero, 27% had 1, 24% had 2, 27% had 3, and 15% had 4 or more. We identified a statistically significant positive "dose-response" relationship between the number of psychosocial problems and CAS with male clients over time, with the greatest odds of engaging in CAS with a male client over follow-up among those with 4 or more psychosocial problems (adjusted odds ratio = 5.18, 95% CI: 1.61 to 16.62).

CONCLUSIONS

Internet escorts and street-based MSW are likely to experience psychosocial problems and engaging in HIV sexual risk with male clients. The accumulation of psychosocial problems additively predicted CAS with male clients in a prospective cohort of MSW. The specification of psychosocial problems presents distinct treatment targets for HIV prevention among MSW in the United States.

Estimating HIV transmissions in a large U.S. clinic-based sample: effects of time and syndemic conditions

INTRODUCTION

Little is known about onward HIV transmissions from people living with HIV (PLWH) in care. Antiretroviral therapy (ART) has increased in potency, and treatment as prevention (TasP) is an important component of ending the epidemic. Syndemic theory has informed modelling of HIV risk but has yet to inform modelling of HIV transmissions.

METHODS

Data were from 61,198 primary HIV care visits for 14,261 PLWH receiving care through the Centers for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS) at seven United States (U.S.) sites from 2007 to 2017. Patient-reported outcomes and measures (PROs) of syndemic conditions - depressive symptoms, anxiety symptoms, drug use (opiates, amphetamines, crack/cocaine) and alcohol use - were collected approximately four to six months apart along with sexual behaviours (mean = 4.3 observations). Counts of syndemic conditions, HIV sexual risk group and time in care were modelled to predict estimated HIV transmissions resulting from sexual behaviour and viral suppression status (HIV RNA < 400/mL) using hierarchical linear modelling.

RESULTS

Patients averaged 0.38 estimated HIV transmissions/100 patients/year for all visits with syndemic conditions measured (down from 0.83, first visit). The final multivariate model showed that per 100 patients, each care visit predicted 0.05 fewer estimated transmissions annually (95% confidence interval (CI): 0.03 to 0.06; p < 0.0005). Cisgender women, cisgender heterosexual men and cisgender men of undisclosed sexual orientation had, respectively, 0.47 (95% CI: 0.35 to 0.59; p < 0.0005), 0.34 (95% CI: 0.20 to 0.49; p < 0.0005) and 0.22 (95% CI: 0.09 to 0.35; p < 0.005) fewer estimated HIV transmissions/100 patients/year than cisgender men who have sex with men (MSM). Each within-patient syndemic condition predicted 0.18 estimated transmissions/100 patients/year (95% CI: 0.12 to 0.24; p < 0.0005). Each between-syndemic condition predicted 0.23 estimated HIV transmissions/100 patients/year (95% CI: 0.17 to 0.28; p < 0.0005).

CONCLUSIONS

Estimated HIV transmissions among PLWH receiving care in well-resourced U.S. clinical settings varied by HIV sexual risk group and decreased with time in care, highlighting the importance of TasP efforts. Syndemic conditions remained a significant predictor of estimated HIV transmissions notwithstanding the effects of HIV sexual risk group and time in care.

Self-Reported Sexual Behavioral Similarities and Differences Among Young Men Who Have Sex With Men With Childhood Sexual Abuse Histories: A Qualitative Exploratory Study

Young men who have sex with men (YMSM) have the highest burden of sexually transmitted infections (STIs), including HIV. Childhood sexual abuse (CSA) is a risk factor for high-risk sexual behavior and STI acquisition. Studies that have explored sexual behavior based on the type of reported sexual abuse are limited. This study aimed to further understand current sexual behaviors and perceptions among YMSM that have experienced different types of CSA. Sixteen YMSM who were survivors of CSA were interviewed utilizing a phenomenological conceptual framework and methodology. Thematic findings were divided into two parts. Part I gave an overview of the entire sample, and themes were as follows: unprotected oral sex used to evaluate penile abnormalities, trust promoting unprotected sex, and alcohol and other drugs not cited as the reason for casual sex. Part II demonstrated the differences among those with a history of CSA involving non-penile-anal intercourse and those with a history of CSA involving penile-anal intercourse. The major themes in Part II were that victims of CSA involving penile-anal intercourse reported the following: a hypersexual self-definition, an STI diagnosis and noncondom use history, and a third sexual partner during sexual activity. Based on the findings, early life experiences such as CSA should be considered when developing preventative sexual health strategies and individuals who experienced penetrative sexual abuse may have different needs which should be further explored.

Application of the "syndemics" theory to explain unprotected sex and transactional sex: A crosssectional study in men who have sex with men (MSM), transgender women, and non-MSM in Colombia

Introduction:

Men who have sex with men (MSM) and transgender women (TW) in Colombia are highly affected by HIV. To improve understanding of the role of HIV risk behaviors in HIV acquisition, we used the syndemic framework, a useful concept to inform prevention efforts.

Objective:

To examine the effect of four psychosocial conditions, namely, forced sex, history of childhood sexual abuse, frequent alcohol use, and illicit drug use on unprotected sex and the synergistic effects (“syndemic” effects) of these conditions on HIV risk behavior.

Materials and methods:

We enrolled a total of 812 males (54.7% men who have sex with men, MSM; 7.3% transgender women, and 38% non-MSM). The participants were recruited from neighborhoods of low socioeconomic status through free HIV-counseling and-testing campaigns. We performed Poisson regression analysis to test the associations and interactions between the four psychosocial conditions and unprotected sex with regular, occasional, and transactional partners. To test the “syndemic” model, we assessed additive and multiplicative interactions.

Results:

The prevalence of any psychosocial condition was 94.9% in transgender women, 60.1% in MSM, and 72.2% in non-MSM. A higher likelihood of transactional sex was associated in MSM (prevalence ratio (PR)=7.41, p<0.001) and non-MSM (PR=2.18, p< 0.001) with three or all four conditions compared to those with one condition. Additive interactions were present for all combinations of psychosocial problems on transactional sex in MSM. No cumulative effect or additive interaction was observed in transgender women.

Conclusions:

Our study highlights the need for bundled mental health programs addressing childhood sexual abuse, illicit drug use, and frequent alcohol use with other HIV prevention programs.

Connecting the dots: a comparison of network analysis and exploratory factor analysis to examine psychosocial syndemic indicators among HIV-negative sexual minority men

Syndemics, or comorbid and mutually reinforcing psychosocial problems, are associated with increased HIV risk among men who have sex with men (MSM). Although the dynamic interplay among syndemic indicators is theorized to be crucial for increasing risk of HIV acquisition, novel approaches are needed to understand how these syndemic problems interrelate. This study examined the associations between nine self-reported syndemic indicators in 194 MSM at high risk of HIV acquisition. We compared exploratory factor analyses (EFA) to a network analysis. In the present study, network analysis consisted of edges representing bidirectional partial polychoric correlations between nodes, which represent psychosocial syndemic indicators. EFA yielded a 1-factor solution including suicidal ideation (SI), injection drug use (IDU), depression, social anxiety, intimate partner violence, substance use, and sexual compulsivity, and excluded heavy drinking and childhood sexual abuse. Network analysis yielded a pattern of interconnectedness with the most central nodes being SI, IDU, substance use, and depression. Statistically significant relationships (absolute edge weights) were found between SI and depression, social anxiety, and IDU, and IDU and substance use. These results suggest that depression and substance use, especially more severe presentations of these conditions such as SI and IDU, are prominent interconnected components of the HIV syndemic among MSM at high risk for HIV acquisition. SI, IDU, substance use, and depression may indeed be prudent targets of intervention. Future research on the inclusion of these syndemic indicators in analytical models involving interaction terms may be warranted.

Examining a Syndemics Network Among Young Latino Men Who Have Sex with Men

BACKGROUND

Although studies consistently find that syndemic indicators are additively associated with increased HIV/STI risk behavior (e.g., condomless anal sex; CAS) among men who have sex with men (MSM), information is lacking about how syndemic indicators are associated with each other. Young Latino MSM are one of the most at-risk groups for acquiring HIV in the U.S. Understanding the associations of syndemic indicators with each other and with CAS may improve understanding of how to enhance sexual and behavioral health in this population.

METHOD

Network analysis using the graphical LASSO (glasso) algorithm was employed to explore associations between CAS and syndemic indicators among 139 young Latino MSM. Structural and psychosocial syndemic indicators were assessed via self-report. CAS was defined as the number of partners in the past 3 months with whom one engaged in CAS.

RESULTS

Results of the network analysis suggested the variables with the highest centrality were unstable housing, prison history, childhood sexual abuse, and CAS. Specific significant associations included links between CAS and alcohol use (b = 0.40), childhood sexual abuse and unstable housing (b = - 0.75), alcohol use and childhood sexual abuse (b = 0.40), and substance use and intimate partner violence (b = 0.43).

CONCLUSION

This pattern of interconnectedness demonstrates the potential for network analysis to examine nuanced interrelationships of syndemic indicators. The specific associations in this sample raise the question whether a primary focus of interventions should address the more central syndemic indicators for this population, such as alcohol use and unstable housing, and whether this would, via downstream effects, affect other aspects of behavioral health in this population.

Using Syndemics Theory to Examine HIV Sexual Risk Among Latinx Men Who Have Sex with Men in Philadelphia, PA: Findings from the National HIV Behavioral Surveillance

Latinx men who have sex with men (MSM) continue to be disproportionately impacted by HIV/AIDS. Identifying the role of multiple syndemic factors associated with sexual risk behaviors is imperative in order to develop effective prevention and treatment strategies. Cross-sectional data for this study were derived from three cycles of the Philadelphia portion of the National HIV Behavioral Surveillance System. This study explored the impact of syndemic factors - heavy drinking, exchange sex, and homophobic discrimination - on sexual HIV risk behaviors, operationalized as number of male partners, and condomless anal intercourse (CAI) with main and casual partners among Latinx MSM (n=464). Analyses took two forms: a syndemic approach, using the cumulative number of conditions as an independent variable; and a non-syndemic approach, incorporating each condition as a unique factor. In multivariable syndemic analyses, participants with two or more factors reported more male partners and more CAI casual male partners than those with none. In non-syndemic models, homophobic discrimination and exchange sex were significantly positively associated with total number of male partners, while heavy drinking was associated with more casual CAI partners. Quantitative results indicate that syndemic and non-syndemic approaches vary in their relative capacity to account for sexual risk among Latinx MSM.

Prevalence and correlates of depressive symptoms among gay, bisexual and other men who have sex with men in the PROUD randomised clinical trial of HIV pre-exposure prophylaxis

OBJECTIVES

The aim of this analysis is to: (i) assess the prevalence of clinically significant depressive symptoms at baseline and follow-up for participants in the PROUD trial of HIV pre-exposure prophylaxis (PrEP), examining changes in prevalence over time and (ii) investigate the association of socioeconomic and psychosocial factors with depression.

METHODS

PROUD was an open label randomised trial evaluating the benefit of PrEP for 544 HIV-negative gay, bisexual and other men who have sex with men (GBMSM) in England. Enrolment was between 2012 and 2014, with at least 2 years follow-up. Prevalence of depression (score ≥10 on Patient Health Questionnaire-9) was assessed and compared across time-points (using McNemar's χ² tests) and between trial arms (using χ² tests). Cross-sectional associations with socioeconomic and psychosocial factors were examined using baseline data in modified Poisson regression models and combined 12 and 24 month follow-up data in generalised estimating equations (GEEs). Prevalence ratios (PRs) were presented as unadjusted PR and adjusted PR (aPR) for age, UK birth, sexual identity, university education, London study clinic site and calendar time (and follow-up time-point in GEEs).

RESULTS

Depression increased significantly from baseline (9.1%; 49/540) to the 12 month (14.4%; 59/410) and 24 month (14.4%; 48/333) follow-ups, possibly explained by underreporting at baseline. The prevalence of depression did not differ by study trial arm, at any time-point. In the baseline analysis, younger age, unemployment and crystal methamphetamine use, was associated with depression. In combined analysis of 12 and 24 month data, measures of intimate partner violence (IPV) (lifetime IPV victimisation aPR 2.57 (95% CI: 1.71 to 3.86)), internalised homophobia (aPR 1.91 (95% CI: 1.29 to 2.83)) and concealment of sexual identity (aPR 1.75 (95% CI: 1.16 to 2.65)), were strongly associated with depression.

CONCLUSIONS

There is a high concomitant burden of psychosocial factors with depression among GBMSM.

Examining the impact of medical legal partnerships in improving outcomes on the HIV care continuum: rationale, design and methods

BACKGROUND

Over the past two decades, we have seen a nationwide increase in the use of medical-legal partnerships (MLPs) to address health disparities affecting vulnerable populations. These partnerships increase medical teams' capacity to address social and environmental threats to patients' health, such as unsafe housing conditions, through partnership with legal professionals. Despite expansions in the use of MLP care models in health care settings, the health outcomes efficacy of MLPs has yet to be examined, particularly for complex chronic conditions such as HIV.

METHODS

This on-going mixed-methods study utilizes institutional case study and intervention mapping methodologies to develop an HIV-specific medical legal partnership logic model. Up-to-date, the organizational qualitative data has been collected. The next steps of this study consists of: (1) recruitment of 100 MLP providers through a national survey of clinics, community-based organizations, and hospitals; (2) in-depth interviewing of 50 dyads of MLP service providers and clients living with HIV to gauge the potential large-scale impact of legal partnerships on addressing the unmet needs of this population; and, (3) the development of an MLP intervention model to improve HIV care continuum outcomes using intervention mapping.

DISCUSSION

The proposed study is highly significant because it targets a vulnerable population, PLWHA, and consists of formative and developmental work to investigate the impact of MLPs on health, legal, and psychosocial outcomes within this population. MLPs offer an integrated approach to healthcare delivery that seems promising for meeting the needs of PLWHA, but has yet to be rigorously assessed within this population.

Patterns of Sexual Behaviors in Young Men Who Have Sex With Men in Mexico

Recent research has documented the importance of understanding the multidimensional nature of sexual risk behavior. However, little is known about patterns of sexual behavior among men who have sex with men (MSM) in Mexico, men who are at greatest risk for HIV and sexually transmitted infections compared to other subpopulations in the country. This study applied latent class analysis to data from a large, HIV-negative sample of 18- to 25-year-old Mexican MSM recruited from a social and sexual networking website (N = 3,722) to uncover multidimensional patterns of sexual behaviors, partner factors, and protective behaviors, and examine how these were associated with health and well-being correlates. We selected a model with seven classes. The most common class included those who reported both insertive and receptive behaviors with more than one partner, but smaller groups of individuals were in classes marked by only insertive or receptive anal sex, romantic relationships, or sexual inactivity. Class membership differed by sexual orientation, age, depressive symptoms, alcohol problems, and self-acceptance, with individuals in a class marked by same-sex relationships generally reporting more positive outcomes. Findings suggest heterogeneity of behaviors among Mexican MSM and the possible efficacy of prevention messages tailored to individuals' specific patterns of sexual behavior.

Longitudinal Analysis of Syndemic Psychosocial Problems Predicting HIV Risk Behavior Among a Multicity Prospective Cohort of Sexually Active Young Transgender Women in the United States

BACKGROUND

Worldwide, young transgender women (YTW) contend with exceptionally high risks of HIV infection. Cross-sectional studies have suggested that co-occurring epidemics or "syndemics" of psychosocial problems may accelerate HIV acquisition and transmission through elevated sexual risk behavior among transgender women. We aimed to examine how a syndemic of 7 psychosocial problems potentiates HIV sexual risk behavior among a multicity, longitudinal cohort of sexually active YTW in the United States.

METHODS

Between 2012 and 2015, 233 YTW from Boston, MA, and Chicago, IL, completed behavioral surveys at baseline, 4, 8, and 12 months. We used generalized estimating equations to examine the prospective relationship of overlapping psychosocial problems and HIV sexual risk behavior (ie, condomless anal or vaginal sex) among YTW.

RESULTS

The prevalence of 7 psychosocial syndemic problems was substantial at baseline and remained high at each time point: 6.4% reported polydrug use in the past 4 months (excluding stimulants); 7.7% reported heavy alcohol use in the past 4 months; 10% reported a history of childhood sexual abuse; 15.9% reported stimulant use in the past 4 months; 41.7% reported experiencing lifetime intimate partner violence; 42.1% reported clinically significant depressive symptoms; and 68.6% reported lifetime transgender-specific victimization. We identified a statistically significant positive "dose-response" relationship between the number of psychosocial syndemic problems and condomless anal or vaginal sex over time.

CONCLUSIONS

The accumulation of "syndemic" psychosocial problems predicted HIV sexual risk behavior in a prospective cohort of YTW. Given the high prevalence of psychosocial problems and HIV sexual risk behavior, as well as having the highest HIV incidence among any risk group, the HIV prevention agenda requires a shift toward improved assessment of psychosocial comorbidities and stronger integration with gender-affirming and supportive mental health, violence recovery, and addiction treatment services for this population.

Longitudinal Effects of Syndemics on HIV-Positive Sexual Minority Men's Sexual Health Behaviors

This study examined the longitudinal effects of co-occurring psychosocial concerns, or syndemics, on HIV-positive sexual minority men's likelihood of engaging in serodiscordant condomless anal sex (CAS), a health behavior with implications for personal and public health. Participants included 390 HIV-positive sexual minority men from two prior secondary prevention trials. Over the course of the 1-year data collection period (up to 5 observations per participant), participants completed self-report measures of CAS, as well as six syndemic factors: post-traumatic stress disorder, childhood sexual abuse, depression, anxiety, alcohol abuse, and polysubstance/stimulant use. We employed multilevel modeling to examine the longitudinal additive effect of syndemics on serodiscordant CAS (binary) over the 1-year period. The number of syndemic conditions was a significant predictor of CAS, with each additional syndemic associated with 1.41 greater odds of CAS (p = .0004; 95% CI [1.16, 1.70]). Both the between-person (p = .0121, 95% CI [1.07, 1.69]) and within-person (p = .01, 95% CI [1.11, 2.10]) effects of syndemics were significant predictors, showing that an increase in the number of syndemic conditions across person and time both increased odds of CAS. Interventions addressing HIV-positive sexual minority men's sexual health behaviors should address the potential impact of co-occurring psychosocial concerns that affect these behaviors. This will benefit this population's personal sexual health and reduce transmission of HIV and STIs among sexual minority men.

Relationship Dynamics in the Context of Binge Drinking and Polydrug Use Among Same-Sex Male Couples in Atlanta, Boston, and Chicago

An estimated one- to two-thirds of incident HIV infections among U.S. men who have sex with men (MSM) occur within the context of a primary relationship. The existing, yet limited, literature on sexual risk behavior among same-sex couples suggests that MSM with main partners are more often to report having lower perceived HIV risk, higher unrecognized HIV infection, and increased frequency of condomless anal intercourse with their primary partner. Furthermore, numerous studies document the strong relationship between polydrug use and binge drinking with HIV infection among MSM. However, more research is needed that identifies how individual- and relationship-level factors are related to polydrug use and binge drinking in the context of same-sex male relationships. We used baseline data collected as part of a prospective randomized controlled trial of 160 same-sex male couples (total N = 320 individuals). In 2015, recruitment commenced in three U.S. cities: Atlanta, GA, Boston, MA, and Chicago, IL. Participants completed a self-report assessment using an audio-computer-assisted self-interview system during their baseline enrollment visit. We collected information on participants' sociodemographic characteristics, drug and alcohol use, individual- and relationship-level variables of interest, as well as relationship quality. Multinomial logistic regression models were fit for three different categories of polydrug use and of binge drinking for which (1) both partners exhibited the behavior, (2) only the respondent exhibited the behavior, or (3) only the partner exhibited the behavior. Participants' age ranged from 18 to 69 (M = 35.9). The sample majority (77.5%) was White (248/320), with 12.2% Black (39/320) and 10.3% Multiracial (33/320); 68.4% had completed a college degree; and 9.6% were unemployed. A high proportion (62.2%) reported any drug use, including marijuana; 45% reported using drugs other than marijuana; and 18.1% reported polydrug use. Overall, 22.2% reported current binge drinking. Age discordance and being in a long-term relationship (6 or more years) were associated with a decreased odds of polydrug use among couples; being in an interracial dyad, recent history of arrest, living with HIV, and self-reported clinically significant depressive symptoms were associated with an increased odds of polydrug use. Additionally, being the older partner and reporting higher levels of internalized homophobia decreased odds for binge drinking, while recent history of arrest, living with HIV, and feeling more loved in their relationship were associated with an increased odds of binge drinking. Findings have implications for developing interventions to reduce substance use and promote health among same-sex male couples. Future research would benefit by using longitudinal study designs to understand the individual-, relationship-, and structural-level factors that potentiate polydrug use and binge drinking among same-sex male couples.

The role of sexual risk behaviors on PrEP awareness and interest among men who have sex with men in Latin America

In Latin America, men who have sex with men (MSM) remain disproportionately impacted by HIV. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention tool and has been FDA approved in the United States since 2012, but no Latin American state, with the recent exception of Brazil, has implemented PrEP guidelines. We carried out a multinational online survey of MSM in Latin America (n = 22698) in 2012 to assess whether MSM at highest risk of HIV acquisition (i.e., those engaging in condomless anal sex [CAS; n = 2606] and transactional sex [n = 1488]) had higher levels of awareness of PrEP, PrEP use and interest in participating in a PrEP trial. After adjusting for demographic and psychosocial characteristics including depressive symptoms, hazardous alcohol use, childhood sexual abuse, and sexual compulsivity, transactional sex and CAS were associated with increased PrEP awareness (aOR = 1.29, 95% CI: 1.05-1.59, p < .001 and aOR = 1.22, 95% CI: 1.11-1.34, p < .001, respectively) and PrEP trial interest (aOR = 1.45, 95% CI: 1.25-1.71, p < .001 and aOR = 1.74, 95% CI: 1.57-1.95, p < .001, respectively). Findings demonstrate substantial awareness of and interest in PrEP among MSM with behavioral risk factors for HIV in Latin America, suggesting that this region is primed for PrEP implementation, which has been slow.

Safer Crack Kits and Smoking Practices: Effectiveness of a Harm Reduction Intervention among Active Crack Users in Mexico City

BACKGROUND

Crack cocaine use has increased rapidly throughout Mexico, coinciding with rising HIV and HCV infections among vulnerable groups. Due to the increased risk of infection among crack users, harm reduction approaches have been identified to reduce the spread of disease. However, Mexico has yet to adopt these techniques for crack users.

OBJECTIVES

To evaluate the impact of a pilot crack kit distribution program on risky smoking behaviors of active crack users in an impoverished colonia of Mexico City, Mexico.

METHODS

Fifty crack kits, containing safer smoking paraphernalia and related health items (i.e., condoms, alcohol wipes, etc.), were distributed to active crack users. A sample of 58 crack users were surveyed prior to the intervention and 35 were successfully relocated and surveyed three months after the intervention. Surveys assessed drug use, crack kit utilization, and smoking practices.

RESULTS

Findings indicate that crack kit utilization was high throughout the sample. Use of risky or unsafe paraphernalia decreased, specifically the use of cans as pipes (Z = -2.653, p = .008). Similarly, Pyrex pipe use increased significantly (Z = -3.132, p = .002). Sharing of paraphernalia also decreased throughout the sample.

CONCLUSION

These findings identify the potential benefits in reducing risky smoking behaviors of crack kit distribution programs in Mexico City. This evidence supports expansion of crack kit programs in Mexico and similar impoverished regions.

Changing the odds: motives for and barriers to reducing HCV-related sexual risk behaviour among HIV-infected MSM previously infected with HCV

Background

Among HIV-infected MSM who have been treated for HCV infection, the HCV reinfection rate is high. It is therefore essential to understand their perceptions of HCV risk behaviour and risk-reducing strategies.

Methods

This qualitative study among 20 HCV-infected MSM, the majority treated in the era before direct acting antivirals, provides insight into their ideas, motives, and barriers concerning HCV risk reduction, and aims to strengthen prevention strategies for both primary HCV infection and HCV reinfection.

Results

The strongest motive to implement risk reduction strategies was the reward of avoiding HCV retreatment and its side effects, but this may change with the current implementation of less burdensome HCV treatment. Also, the sexual risk norms in the MSM scene, including social pressure towards risk-taking, HCV stigma, and non-disclosure of HCV status, all form barriers to safe sex. Drug use, strongly present in the context of clubs and group sex, directly impedes the self-efficacy of men to take risk reduction measures.

Conclusions

Tailored prevention messages, empowerment of self-efficacy for risk reduction, and more insight into risk behaviour over time are ingredients for effective HCV prevention among these men.

Syndemic Vulnerability and Condomless Sex Among Incarcerated Men in Mexico City: A Latent Class Analysis

In order to address common statistical and population-based limitations in epidemiological literature applying syndemic theory, this study uses latent class analysis (LCA) to explore how health and social problems coalesce and shape sexual risk behaviors linked to HIV transmission in three Mexico City prisons. Among the studied male inmates, LCA identified four classes, defined by low syndemic risk (61.4%); marijuana (14.3%); depression, substances, and trauma (19.7%); and depression, substances, and marijuana (4.7%). In multinomial regression models, classes with a greater number of syndemic exposures were associated with increased odds of condomless anal sex during incarceration. In analyses stratified by pre-incarceration sexual risk behaviors, however, high syndemic burden classes were associated with condomless anal sex during incarceration differently. Overall, the study findings suggest that LCA has potential utility for syndemic analyses and highlight the need to attend to health and social adversities when addressing sexual risk behaviors and HIV transmission during incarceration.

Longitudinal Effects of Syndemics on ART Non-adherence Among Sexual Minority Men

This study examined longitudinally the additive effect of syndemics, or co-occurring psychosocial problems, on antiretroviral treatment (ART) non-adherence among 390 HIV-positive sexual minority men. Participants completed measures of ART adherence (reduced to a non-adherence score using exploratory factor analysis) and six syndemic conditions. We employed multilevel modeling with the number of syndemics as a longitudinal predictor of non-adherence, and logistic regression with baseline syndemics predicting follow up viral load. Number of syndemics was a significant longitudinal predictor of non-adherence, with each additional syndemic associated with a 0.13 increase in non-adherence (p = 0.004). Each additional syndemic was also associated with 1.27 greater odds of detectable viral load (p = 0.002). Among HIV-positive sexual minority men in this sample, more syndemics were associated with lower ART adherence and greater odds of detectable viral load, suggesting the need for behavioral intervention to facilitate care for this population.

A randomized clinical efficacy trial of a psychosocial intervention to strengthen self-acceptance and reduce HIV risk for MSM in India: study protocol

BACKGROUND

Men who have sex with men (MSM) in India are a key group at risk for HIV acquisition and transmission. They are also an extremely marginalized and stigmatized population, facing immense psychosocial stressors including, but not limited to, stigma, homophobia, discrimination, criminalization, low self-esteem, low self-acceptance, distress, and, as a result, high rates of mental health problems. Although these multi-level psychosocial problems may put MSM at high risk for HIV acquisition and transmission, currently HIV prevention interventions in India do not address them. This paper describes the design of a psychosocial intervention to reduce HIV risk for MSM in India.

METHODS

Funded by the National Institute of Mental Health, this study is a two-arm randomized clinical efficacy trial of a self-acceptance based psychosocial HIV prevention intervention, informed by the minority stress model and syndemic theory, that was developed with extensive community-based formative work and input from the Indian MSM community and key informants who are knowledgeable about the experiences faced by MSM in India. Participants are MSM in Chennai and Mumbai who endorsed recent sexual behaviors placing them at high risk for HIV/sexually transmitted infection (STI) acquisition and transmission. Enrolled participants are equally randomized to either 1) the experimental condition, which consists of four group and six individual counseling sessions and includes standard of care HIV/STI testing and counseling, or 2) the standard of care condition, which includes HIV/STI testing and counseling alone. The primary outcomes are changes in the frequency of condomless anal sex acts and STI incidence (syphilis seropositivity and urethral, rectal, and pharyngeal gonorrhea and chlamydia infection. Major study assessment visits occur at baseline, 4-, 8-, and 12-months.

DISCUSSION

HIV prevention interventions that address the psychosocial stressors faced by MSM in India are needed; this study will examine the efficacy of such an intervention. If the intervention is successful, it may be able to reduce the national HIV/AIDS burden in India while empowering a marginalized and highly stigmatized group.

Condom-use self-efficacy as a mediator between syndemics and condomless sex in men who have sex with men (MSM)

OBJECTIVE

Among men who have sex with men (MSM), HIV sexual risk and poor self-care behavior is associated with syndemics, or co-occurring psychosocial problems. Though prior research has demonstrated an additive total effect of syndemics on HIV risk behavior and infection, mostly within cross-sectional designs, it is possible that these associations are not direct but rather that syndemics disrupt relevant individual-level mediating psychological variables. One of the more common individual-level psychological variables that predicts health behavior generally, and HIV risk behavior specifically, is self-efficacy. This study sought to examine the potential effects of syndemics on condomless sex via condom-use self-efficacy as an intermediary variable.

METHOD

In high-risk MSM (N = 197), across 3 time points (baseline, 3 months, and 6 months) we used latent growth curve modeling to test the degree to which self-efficacy mediated the relationship between syndemics (heavy alcohol use, substance use disorder, sexual compulsivity, depression, social anxiety, intimate partner violence, childhood sexual abuse) and condomless anal sex.

RESULTS

The baseline analyses were consistent with an indirect effect of the association between syndemics and condomless sex through self-efficacy. Prospective longitudinal mediation was partially supported, such that baseline syndemics were associated with lower baseline self-efficacy, which in turn predicted higher increases in condomless anal sex across time.

CONCLUSIONS

These findings provide preliminary evidence (due to the partial support for the longitudinal model) that syndemics themselves may not be directly causal in their association with condomless sex, but the association may be through modifiable social-cognitive mechanisms such as condom self-efficacy.

Depressive Symptoms, Alcohol and Drug Use, and Physical and Sexual Abuse Among Men Who Have Sex with Men in Kisumu, Kenya: The Anza Mapema Study

Men who have sex with men (MSM) are disproportionately burdened by depressive symptoms and psychosocial conditions including alcohol and substance abuse as well as physical and sexual abuse. We examined sociodemographic and psychosocial factors associated with depressive symptoms at baseline among a cohort of MSM in Kisumu, Kenya. Depressive symptoms were assessed via the Personal Health Questionnaire 9 instrument and examined dichotomously. We performed multivariable modified Poisson regression with robust standard errors for the binary outcome. Among 711 participants: 11.4% reported severe depressive symptoms; 50.1% reported harmful alcohol abuse; 23.8% reported moderate substance abuse; 80.9% reported any childhood physical or sexual abuse; and 39.1% experienced recent trauma due to same-sex behaviors. In the final multivariable model, severe depressive symptoms were more common for men who were ≥ 30 years old, had completed ≤ 8 years of education, had experienced childhood physical or sexual abuse, and had recently experienced trauma due to same-sex behaviors. Our results demonstrate that comprehensive services capable of identifying and addressing depressive symptoms, alcohol and substance abuse, and physical and sexual abuse must be expanded within this sample of MSM.

HIV treatment optimism and crystal methamphetamine use and initiation among HIV-negative men who have sex with men in Vancouver, Canada: A longitudinal analysis

BACKGROUND

Treatment as Prevention (TasP) leading to increased HIV treatment optimism among men who have sex with men (MSM) has been previously associated with behavioural risk compensation, though not yet via crystal methamphetamine (CM) use. Among HIV-negative MSM in a TasP environment, this study aimed to investigate the prevalence of recent CM use over time, examine the association between HIV treatment optimism and CM use and initiation, and identify correlates of recent CM use and predictors of CM initiation.

METHODS

Using data from a prospective behavioural cohort study of sexually active MSM in the Vancouver area, we used multi-level generalized mixed effect models to evaluate temporal trends in CM use, univariable and multivariable logistic regression to identify covariates of recent CM use, and univariable and multivariable survival analysis to identify predictors of CM initiation.

RESULTS

Of 497 HIV-negative cohort participants, 10.3% reported any recent CM use at enrollment. From 2012-2016, there were no statistically significant temporal trends in overall CM use or with routes of administration. In multivariable logistic regression analyses, HIV treatment optimism was not associated with recent CM use (not retained in final model) or CM initiation (aHR = 1.06, 95% CI:0.98-1.15). Significant correlates of CM use include recent gamma-hydroxybutyrate (GHB) and ecstasy use, and having received/given drugs for sex.

CONCLUSIONS

Among HIV-negative MSM in Vancouver, HIV treatment optimism does not appear to be independently associated with CM use or initiation of use, though use of CM was both prevalent and stable over time.

Syndemics among individuals enrolled in the PrEP Brasil Study

BACKGROUND

Concurrent psychosocial problems may synergistically increase the risk of HIV infection (syndemics), representing a challenge for prevention. We aimed to evaluate the prevalence and associated factors of syndemics among men who have sex with men (MSM) and transgender women (TGW) enrolled in the Brazilian pre-exposure prophylaxis demonstration study (PrEP Brasil Study).

METHODS

Secondary cross-sectional analysis of the PrEP Brasil Study was performed. Of 450 HIV-seronegative MSM/TGW enrolled in the PrEP Brasil Study- conducted at Rio de Janeiro and São Paulo, Brazil- 421 participants with complete data were included in the present analysis. Syndemics was defined as occurrence of ≥2 of the following conditions: polysubstance (≥2) use, binge drinking, positive depression screen, compulsive sexual behavior, and intimate partner violence (IPV).

RESULTS

The prevalence of recent polysubstance use was 22.8%, binge drinking 51.1%, positive depression screening 5.2%, compulsive sexual behavior 7.1%, and IPV 7.3%. Syndemics prevalence was 24.2%, and associated factors were younger age (adjusted Odds Ratio (aOR) 0.95, 95% Confidence Interval (95% CI) 0.92-0.98 per year increase), TGW vs. MSM (aOR 3.09, 95% CI: 1.2-8.0), some college education or more vs. less than college (aOR 2.49, 95% CI: 1.31-4.75), and multiple male sexual partners in prior 3 months (aOR 1.69, 95% CI: 0.92-3.14).

CONCLUSION

Given the high prevalence of syndemics, particularly of polysubstance use and binge drinking, PrEP delivery offers an opportunity to diagnose and intervene in mental and social well-being.

Estimating the HIV undiagnosed population in Catalonia, Spain: descriptive and comparative data analysis to identify differences in MSM stratified by migrant and Spanish-born population

OBJECTIVE

Undiagnosed HIV continues to be a hindrance to efforts aimed at reducing incidence of HIV. The objective of this study was to provide an estimate of the HIV undiagnosed population in Catalonia and compare the HIV care cascade with this step included between high-risk populations.

METHODS

To estimate HIV incidence, time between infection and diagnosis and the undiagnosed population stratified by CD4 count, we used the ECDC HIV Modelling Tool V.1.2.2. This model uses data on new HIV and AIDS diagnoses from the Catalan HIV/AIDS surveillance system from 2001 to 2013. Data used to estimate the proportion of people enrolled, on ART and virally suppressed in the HIV care cascade were derived from the PISCIS cohort.

RESULTS

The total number of people living with HIV (PLHIV) in Catalonia in 2013 was 34 729 (32 740 to 36 827), with 12.3% (11.8 to 18.1) of whom were undiagnosed. By 2013, there were 8458 (8101 to 9079) Spanish-born men who have sex with men (MSM) and 2538 (2334 to 2918) migrant MSM living with HIV in Catalonia. A greater proportion of migrant MSM than local MSM was undiagnosed (32% vs 22%). In the subsequent steps of the HIV care cascade, migrants MSM experience greater losses than the Spanish-born MSM: in retention in care (74% vs 55%), in the proportion on combination antiretroviral treatment (70% vs 50%) and virally suppressed (65% vs 46%).

CONCLUSIONS

By the end of 2013, there were an estimated 34 729 PLHIV in Catalonia, of whom 4271 were still undiagnosed. This study shows that the Catalan epidemic of HIV has continued to expand with the key group sustaining HIV transmission being MSM living with undiagnosed HIV.

Psychosocial Syndemic Correlates of Sexual Compulsivity Among Men Who Have Sex with Men: A Meta-Analysis

Efforts have been made to better understand sexual compulsivity by examining salient psychosocial syndemic correlates, though examination of such factors has yielded inconclusive results. Given that research on sexual compulsivity has predominately involved men who have sex with men (MSM), the aims of the current study were to establish the mean effect sizes of seven psychosocial syndemic indicators with sexual compulsivity, to determine if the effect varied as a function of the type of psychosocial syndemic, and investigate the potential moderating effects using MSM samples. A total of 95 studies were included for analyses among the psychosocial syndemic indicators of interest (i.e., depression, anxiety, alcohol use, drug use, intimate partner violence, childhood sexual abuse, and sexual risk behavior). Results revealed a medium mean effect size of sexual compulsivity, the strength of which was significantly moderated by type of psychosocial syndemic indicator. Significant mean effect sizes for all syndemic indicators on sexual compulsivity were found, with depression and anxiety having the strongest relationships; significant moderating effects were found and are discussed. Findings highlight clinical considerations regarding sexual compulsivity and its role within the HIV syndemic framework among MSM.

Financial Hardship, Condomless Anal Intercourse and HIV Risk Among Men Who Have Sex with Men

The objective of this study was to examine the association between financial hardship, condomless anal intercourse and HIV risk among a sample of men who have sex with men (MSM). Users of a popular geosocial networking application in Paris were shown an advertisement with text encouraging them to complete a anonymous web-based survey (n = 580). In adjusted multivariate models, high financial hardship (compared to low financial hardship) was associated with engagement in condomless anal intercourse (aRR 1.28; 95% CI 1.08-1.52), engagement in condomless receptive anal intercourse (aRR 1.34; 95% CI 1.07-1.67), engagement in condomless insertive anal intercourse (aRR 1.30; 95% CI 1.01-1.67), engagement in transactional sex (aRR 2.36; 95% CI 1.47-3.79) and infection with non-HIV STIs (aRR 1.50; 95% CI 1.07-2.10). This study suggests that interventions to reduce financial hardships (e.g., income-based strategies to ensure meeting of basic necessities) could decrease sexual risk behaviors in MSM.

Examining the Correlates of Sexually Transmitted Infection Testing Among Men Who Have Sex With Men in Ouagadougou and Bobo-Dioulasso, Burkina Faso

BACKGROUND

Men who have sex with men (MSM) are a population at risk for HIV acquisition and transmission and other sexually transmitted infections (STIs). In Burkina Faso, the prevalence of HIV among MSM is higher than that of other reproductive-aged adults. Early and frequent STI testing and treatment can help prevent HIV acquisition and transmission and may improve linkage to care.

METHODS

A cross-sectional study used respondent-driven sampling of MSM in the urban centers of Ouagadougou and Bobo-Dioulasso, Burkina Faso, to complete a questionnaire and HIV and syphilis testing. The binary-dependent variable in these analyses was self-reported prior STI testing in the past 12 months. Independent variables included sociodemographic characteristics, sexual behaviors, and psychosocial factors, selected according to the modified social ecological model. Bivariate associations at the P<0.05 level were used to create a manual forward stepwise multivariable logistic regression.

RESULTS

Seventy-six percent of participants (511/672) did not test for STIs in the last 12 months. Testing for STIs was associated with STI symptoms (odds ratio [OR], 2.56; 95% confidence interval [95% CI], 1.39-4.76) and independently associated with depressive symptoms (adjusted OR, 1.49; 95% CI, 1.01-2.20) and discussing HIV and STIs with main male partners (adjusted OR, 1.73; 95% CI, 1.23-1.76).

CONCLUSIONS

These data suggest that periodic targeted STI screening for MSM in Burkina Faso may represent an important component of comprehensive HIV prevention programming. The relationship between depression and STI risks is well established, and these data further indicate that screening for depression may be warranted during these clinical encounters.

Correlates of condomless anal sex among men who have sex with men (MSM) in Tijuana, Mexico: The role of public sex venues

Condomless anal sex between male partners is the primary risk factor for HIV transmission among men who have sex with men (MSM). Correlates of condomless anal sex have been well-studied in developed countries, but they have received less attention in lower-to-middle income countries (LMIC), where MSM are often subject to stigma, discrimination, intolerance, and even the criminalization of same sex behavior. In Mexico, a LMIC where traditional views on homosexuality are common, HIV prevalence among MSM is high (16.9%), yet little research has been conducted on the correlates of condomless anal sex in this high-risk population. The present study examined correlates of condomless anal sex among 201 MSM recruited in Tijuana, Mexico, with a focus on the role of public sex venues in relation to sexual risk behavior. Eligibility requirements were: biologically male, 18 years of age or older, resident of Tijuana, and self-reported anal or oral sex with a male partner in the past year. Participants completed an interviewer-administered, demographic and psychosocial survey, and were tested for HIV and syphilis. A hierarchical multiple linear regression model was tested to identify correlates of condomless anal sex. Thirty-eight percent of participants (N = 76) reported condomless anal sex with a male partner in the past 2 months. Higher levels of condomless anal sex were associated with higher levels of depressive symptoms, greater sexual compulsivity, and more frequent seeking out of sex partners in a public venue in the past 2 months. In view of these findings, we recommend the development of multi-level, “combination” interventions, which in the Mexican context should include enhanced condom promotion and distribution, improved availability and access to mental health treatment and counseling services, and expanded HIV/STI testing in public venues.

Substance Use Disorders, Violence, Mental Health, and HIV: Differentiating a Syndemic Factor by Gender and Sexuality

This paper measures syndemic substance use disorder, violence, and mental health and compares the syndemic among HIV-infected heterosexual men, heterosexual women, and men who have sex with men (MSM). Data were from a sample of high needs substance-using, HIV-infected people in South Florida between 2010 and 2012 (n = 481). We used confirmatory factor analysis to measure a syndemic latent variable and applied measurement invariance models to identify group differences in the data structure of syndemic co-morbidities among heterosexual men, heterosexual women, and MSM. We found that variables used to measure the syndemic fit each sub-group, supporting that substance use disorder, violence, and mental health coincide in HIV-infected individuals. Heterosexual men and MSM demonstrated similar syndemic latent variable factor loadings, but significantly different item intercepts, indicating that heterosexual men had larger mean values on substance use disorder, anxiety, and depression than MSM. Heterosexual men and heterosexual women demonstrated significantly different syndemic variable factor loadings, indicating that anxiety and depression contribute more (and substance use contributes less) to the syndemic in heterosexual men compared to heterosexual women. MSM and heterosexual women demonstrated similar syndemic latent variable factor loadings and intercepts, but had significantly different factor residual variances indicating more variance in violent victimization and depression for MSM and more variance in stress for heterosexual women than what is captured by the observed syndemic indicators. Furthermore, heterosexual women had a larger syndemic factor mean than MSM, indicating that the syndemic burden is greater among heterosexual women than MSM. Our findings support that measurement invariance can elucidate differences in the syndemic to tailor interventions to sub-group needs.

Critical Review: When the Party is Over: A Systematic Review of Behavioral Interventions for Substance-Using Men Who Have Sex with Men

Because problematic patterns of alcohol and other substance use are prevalent drivers of the HIV/AIDS epidemic, comprehensive interventions are needed for substance-using men who have sex with men (SUMSM). We conducted a systematic review of 12 randomized controlled trials (RCTs) of behavioral interventions for reducing condomless anal intercourse (CAI) in SUMSM. Three RCTs observed that cognitive behavioral or motivational interviewing interventions achieved a 24% to 40% decrease in CAI. Interventions also tended to demonstrate greater efficacy for reducing CAI and substance use among those who had lower severity of substance use disorder symptoms. Although behavioral interventions for SUMSM are one potentially important component of biobehavioral HIV/AIDS prevention, further research is needed to examine whether integrative approaches that cultivate resilience and target co-occurring syndemic conditions demonstrate greater efficacy. Multilevel intervention approaches are also needed to optimize the effectiveness of pre-exposure prophylaxis and HIV treatment as prevention with SUMSM.

The role of distress intolerance in the relationship between childhood sexual abuse and problematic alcohol use among Latin American MSM

BACKGROUND

Despite the high prevalence of childhood sexual abuse (CSA) among men who have sex with men (MSM) and its well-documented association with substance use in adulthood, little research has examined the psychological mechanisms underlying this association. The current study utilized a large, multinational sample of MSM in Latin America to examine the role of distress intolerance (i.e., decreased capacity to withstand negative psychological states) in the relationship between childhood sexual abuse history and problematic alcohol use.

METHODS

As part of an online survey conducted among members of the largest social/sexual networking website for MSM in Latin America, participants (n=19,451) completed measures of childhood sexual abuse history, distress intolerance, and problematic alcohol use (CAGE score>=2).

RESULTS

Participants who reported a history of childhood sexual abuse indicated higher levels of distress intolerance, which was in turn associated with greater odds of engaging in problematic alcohol use. A mediation analysis further showed that distress intolerance partially accounted for the significant association between childhood sexual abuse history and problematic alcohol use.

CONCLUSION

These findings provide initial evidence for the role of distress intolerance as a process through which early trauma shapes MSM health later in life. These findings also underscore the potential utility of addressing distress intolerance in alcohol use prevention and intervention efforts that target MSM with a history of childhood sexual abuse.

Bridging Health Disparity Gaps through the Use of Medical Legal Partnerships in Patient Care: A Systematic Review

Over the past two decades, we have seen an increase in the use of medical-legal partnerships (MLPs) in health-care and/or legal settings to address health disparities affecting vulnerable populations. MLPs increase medical teams' capacity to address social and environmental threats to patients' health, such as unsafe housing conditions, through partnership with legal professionals. Following the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines, we systematically reviewed observational studies published from January 1993-January 2016 to investigate the capacity of MLPs to address legal and health disparities. We identified 13 articles for qualitative analysis from an initial pool of 355 records. The resulting pool of 13 articles revealed more information regarding the capacity of MLPs to address legal outcomes than their capacity to address health outcomes; only 4 studies directly addressed the impact of MLP intervention on patient wellbeing and/or patient utilization of healthcare services. We call for further evaluation/longitudinal studies that specifically address MLPs' short and long term effects upon patient health disparities. Finally, given the demonstrated capacity of MLPs to address unmet legal needs, and their evident potential in regards to improving health outcomes, we present the MLP model as a framework to address HIV-related legal and health disparities.

Prevalence of non-contact and contact childhood sexual abuse: An Internet-based sample of men who have sex with men in China

Background

The prevalence of childhood sexual abuse (CSA) is high among Western men who have sex with men (MSM), and CSA is associated with certain socio-demographic variables and with human immunodeficiency virus (HIV) status. Little is known about CSA among Chinese MSM; therefore, we explored the prevalence and frequency of non-contact (e.g., sexual invitations, exhibitionism) and contact (e.g., intercourse, genital contact) forms of CSA in an Internet-based sample of MSM in China. We also examined the associations between the participants’ socio-demographic characteristics and HIV status, and their histories of CSA.

Methods

We surveyed MSM from 30 Chinese provinces in 2014–2015; 1,030 (mean age = 25.15 years, SD = 6.32) and 1,020 (mean age = 25.05 years, SD = 5.95) respondents were eligible for inclusion in the non-contact and contact CSA groups, respectively.

Results

Prevalence of non-contact and contact CSA was 36.2% and 29.8%, respectively; 20.4% and 15.0% had experienced non-contact and contact CSA ≥ 3 times, respectively. Most respondents were young adults, well educated, single, had never “come out,” and self-identified as gay or bisexual men. Univariate analyses showed that respondents who had experienced contact CSA were more likely to be HIV-positive than those who had never experienced contact CSA. Multivariate analyses showed that non-contact CSA was associated with less education, being in a relationship with a woman or a man, and having “come out.” Contact CSA was associated with less education, higher income, and being in a relationship with a man. Respondents who had experienced non-contact CSA ≥ 3 times were more likely to be less educated, “out,” and to be in a relationship with a woman or a man. Respondents who had experienced contact CSA ≥ 3 times were more likely to be less educated and to be in a relationship with a man.

Conclusions

It is necessary to pay closer attention to CSA among MSM and other sexual minorities in China.
