Amphetamine-Type-Stimulants (ATS) Use and Homosexuality-Related Enacted Stigma Are Associated With Depression Among Men Who Have Sex With Men (MSM) in Two Major Cities in Vietnam in 2014

Detection Rates of Mental Health Problems Among Sexual Minorities in Mainland China: A Meta-Analysis

Previous studies that have addressed the growing mental health problems among sexual minorities in mainland China, but failed to inform mental health programs and public health policies with consistent detection results. To obtain robust results on aggregate detection rates and moderators of these problems, we performed a meta-analysis of the related Chinese and English literature published before 2022. Ultimately, 305 eligible studies (ndepression = 127, nanxiety = 71, nsuicide ideation = 55, nsuicide plan = 13, nsuicide attempt = 39) were pooled in the analysis. The results revealed "Money boys" and people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) had higher detection rates than general men who have sex with men. Depression was more prevalent in gays than lesbians, and the latter had a higher detection rate of suicide. Detection rates of anxiety and depression among sexual minorities in China were moderated by detection time, measurement tools, and their detection thresholds. Suggested future priorities include developing more targeted measurement tools that consider the living conditions and psychological characteristics of local sexual minorities, enhancing mental health programs for sexual minorities, and devising more practical and effective interventions to prevent and reduce their mental health problems.

Prevalence of methamphetamine use among gay, bisexual and other men who have sex with men: A systematic review and meta-analysis

BACKGROUND

International efforts have reduced the availability of methamphetamine precursors, but its distribution and use continue to rise. Methamphetamine use can lead to short- and long-term adverse effects, including addiction, physical and psychosocial health problems, socioeconomic troubles, incarceration, overdose, and death. Gay, bisexual, and other men who have sex with men (MSM) have been shown to have an elevated prevalence of methamphetamine use.

METHODS

We conducted a systematic review and meta-analysis to estimate the prevalence of methamphetamine use among MSM. We searched electronic databases, such as PubMed, for peer-reviewed literature published between 2011 and 2022. Data on methamphetamine use were extracted, including study features, location, study design, sampling method, recruitment period, specific MSM subgroups, prevalence period, and demographics. Employing a random-effects model, we computed the pooled prevalence of methamphetamine use among MSM across two prevalence periods: recent use (i.e., one month, three months, six months, one year) and lifetime use.

RESULTS

The systematic review included 56 studies with a total of 25,953 MSM who use methamphetamine. Most studies were conducted in Europe, with the highest prevalence reported in the United Kingdom. The studies primarily used cross-sectional or cohort study designs with convenience sampling. The pooled prevalence rates across recent use (i.e., past month, past three months, past six months, and past year) was 15% (95% CI [11-19%]). Additionally, we pooled lifetime use, which was 23% (95% CI [9-38%]). High heterogeneity (I2 > 99%) was observed, indicating significant variation.

CONCLUSION

This systematic review and meta-analysis provide a pooled prevalence of methamphetamine use among MSM. The analysis accounts for study design, prevalence period, specific MSM subgroups, and geographical areas to estimate methamphetamine use in diverse settings and populations. The review highlights the need for targeted interventions and harm reduction strategies focused on prevention, education, healthcare access, and stakeholder collaboration to address the multifaceted challenges of methamphetamine use among MSM.

Validation of the combined Patient Health Questionnaire Anxiety and Depression Scale among people with HIV in Vietnam

BACKGROUND

Our study aims to examine the factor structure, validity, and reliability of the combined scale Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS) among people with HIV (PWH) in Vietnam.

METHODS

Baseline data from an alcohol-reduction intervention trial among ART clients in Thai Nguyen, Vietnam were used for this analysis (n = 1547). A score ≥10 on the PHQ-9, GAD-7 and PHQ-ADS scale was considered having clinically meaningful depression, anxiety and distress symptoms. Factor structure of the combined PHQ-ADS scale was validated using confirmatory factor analysis, and three models were tested: a one-factor, a two-factor, and a bi-factor model. Reliability and construct validity were examined.

RESULTS

The prevalence of clinically meaningful depression and anxiety symptoms was 7% and 2%, respectively, while 19% had distress symptoms. A bi-factor model had the best fit to the data (RMSEA = 0.048; CFI = 0.99; TLI = 0.98). The Omega index of the bi-factor model was 0.97. The scale showed good construct validity through negative associations between depression, anxiety, distress symptoms and quality of life.

CONCLUSIONS

Our study supports the use of a combined scale to measure general distress for PWH, which has good validity, reliability and is unidimensional enough to justify the use of a composite depression and anxiety score.

The global prevalence of suicidal ideation and suicide attempts among men who have sex with men: a systematic review and meta-analysis

BACKGROUND

This study aimed to determine the global prevalence of suicidal ideation and attempts among men who have sex with men (MSM) as a systematic review, and meta-analysis.

METHODS

For this meta-analysis, a search in four international databases (PubMed, Scopus, Web of Science, and EMBASE) was designed, and performed. In the next step, the information extraction checklist was prepared based on the study authors' opinions, and the quality of the articles was evaluated using the Newcastle-Ottawa scale (NOS) checklist. Data meta-analysis was performed using STATA16 software with a significance level below 0.05.

RESULTS

The results showed the prevalence of suicidal ideation, and suicide attempts among MSM was 21% (95% CI 17%-26%), and 12% (95% CI 8%-17%), respectively. The results of the subgroup analysis showed that the prevalence of suicidal ideation in the population of MSM living with Human immunodeficiency virus (HIV) was 40% (95% CI 35%-45%), and the prevalence of suicide attempts among MSM with HIV was 10% (95% CI 1%-27%). The prevalence of suicidal ideation in European MSM, and the prevalence of suicide attempts among American MSM were higher than other MSM in other geographical areas.

CONCLUSION

Considering that the prevalence of suicidal ideation and attempts among these people is many times higher than that among men in the general population, developing programs for the prevention of mental disorders with special attention to suicide is necessary for these people. Screening programs are also recommended for early diagnosis and prevention of suicide among these people.

Chemsex and chemsex associated substance use among men who have sex with men in Asia: A systematic review and meta-analysis

BACKGROUND

The prevalence of chemsex has been reported by multiple systematic reviews among men who have sex with men (MSM) focussing predominantly on the Global North. An Asian perspective with meta-analytical evidence is missing. This meta-analysis summarised the prevalence of substance use associated with chemsex, and chemsex activity among MSM and MSM sub-populations in Asia, as well as the likelihood for chemsex among MSM living with or without HIV.

METHODS

We utilized PubMed, Web of Science and medRxiv to search for literature describing chemsex and its associated substance use among MSM and MSM sub-populations in Asia from January 1, 2010 to November 1, 2021 to conduct three meta-analyses with both frequentist and Bayesian approaches.

RESULTS

We identified 219 studies and included 23 in the meta-analysis. Based on the frequentist models, methamphetamine was the default substance associated with chemsex among MSM in Asia (prevalence = 0.16, 95 %CI:0.09-0.22), followed by GHB/GBL (prevalence = 0.15, 95 %CI:0.03-0.27) and ketamine (prevalence = 0.08, 95 %CI:0.04-0.12), but hardly any cocaine (prevalence = 0.01, 95 %CI:0.00-0.03). Compared to a general MSM population (prevalence = 0.19, 95 %CI:0.15-0.23), MSM engaging in transactional sex showed a higher prevalence of chemsex (MSM sex work clients [prevalence = 0.28, 95 %CI:0.11-0.45]; MSM sex worker [prevalence = 0.28, 95 %CI:0.17-0.26]). MSM living with HIV also showed higher odds of chemsex activity (OR = 3.35, 95 %CI:1.57-7.10), compared to MSM living without HIV. Both meta-analytic models converged, indicating robust evidence.

CONCLUSIONS

Our meta-analyses showed that chemsex is not uncommon among MSM, and MSM engaging in transactional sex in Asia. We confirmed that MSM living with HIV have a higher likelihood of engaging in chemsex, too. Chemsex prevention and management strategies in Asia should be adjusted accordingly.

Predicting the risk of HIV infection among internal migrant MSM in China: An optimal model based on three variable selection methods

Introduction

Internal migrant Men who have sex with men (IMMSM), which has the dual identity of MSM and floating population, should be more concerned among the vulnerable groups for HIV in society. Establishing appropriate prediction models to assess the risk of HIV infection among IMMSM is of great significance to against HIV infection and transmission.

Methods

HIV and syphilis infection were detected using rapid test kits, and other 30 variables were collected among IMMSM through questionnaire. Taking HIV infection status as the dependent variable, three methods were used to screen predictors and three prediction models were developed respectively. The Hosmer-Lemeshow test was performed to verify the fit of the models, and the net classification improvement and integrated discrimination improvement were used to compare these models to determine the optimal model. Based on the optimal model, a prediction nomogram was developed as an instrument to assess the risk of HIV infection among IMMSM. To quantify the predictive ability of the nomogram, the C-index measurement was performed, and internal validation was performed using bootstrap method. The receiver operating characteristic (ROC) curve, calibration plot and dynamic component analysis (DCA) were respectively performed to assess the efficacy, accuracy and clinical utility of the prediction nomogram.

Results

In this study, 12.52% IMMSMs were tested HIV-positive and 8.0% IMMSMs were tested syphilis-positive. Model A, model B, and model C fitted well, and model B was the optimal model. A nomogram was developed based on the model B. The C-index of the nomogram was 0.757 (95% CI: 0.701-0.812), and the C-index of internal verification was 0.705.

Conclusions

The model established by stepwise selection methods incorporating 11 risk factors (age, education, marriage, monthly income, verbal violence, syphilis, score of CUSS, score of RSES, score of ULS, score of ES and score of DS) was the optimal model that achieved the best predictive power. The risk nomogram based on the optimal model had relatively good efficacy, accuracy and clinical utility in identifying internal migrant MSM at high-risk for HIV infection, which is helpful for developing targeted intervention for them.

Effects of Two Alcohol Reduction Interventions on Depression and Anxiety Symptoms of ART Clients in Vietnam

Little is known about the potential mental health impacts of cognitive behavioral therapy and motivational interviewing interventions that focus on alcohol reduction among people with HIV (PWH). Our study aimed to assess the impact of two evidence-based alcohol reduction interventions on depression and anxiety symptoms of antiretroviral therapy (ART) clients with hazardous alcohol use. We conducted a secondary data analysis of data from a three-arm randomized controlled trial among ART clients in Thai Nguyen, Vietnam that evaluated the impacts of two alcohol reduction interventions in Vietnam. ART clients 18 years old or more with hazardous alcohol use (based on the Alcohol Use Disorders Identification Test-Consumption) were enrolled and randomized into one of three arms: Combined intervention, Brief intervention, and Standard of care (SOC). Symptoms of depression, measured with the Patient Health Questionnaire-9, and anxiety, measured with the Generalized Anxiety Disorder-7 scale, were assessed at baseline and 3, 6, and 12 months post-intervention. Generalized estimating equations were used to evaluate the effects of the interventions on depression and anxiety symptoms. The prevalence of depression and anxiety symptoms at baseline was 25.1% and 16.1%, respectively. Decreases in depression and anxiety symptoms were observed in all three arms from baseline to 12-month follow-up. There were no significant differences in depression and anxiety symptoms among participants receiving either intervention, relative to the SOC. Interventions with a dual focus on alcohol and mental health are needed to achieve more pronounced and sustainable improvements in depression and anxiety symptoms for PWH with hazardous alcohol use.

Perception of discrimination due to sexual orientation and associated factors among men who have sex with men in 12 Brazilian cities

Discrimination due to sexual orientation (DDSO) has an important association with health outcomes among men who have sex with men (MSM). This study aimed to analyze factors associated with DDSO among MSM in 12 Brazilian cities. This is a cross-sectional study with 4,176 MSM participants recruited in 2016 which used a respondent-driven sampling method in 12 Brazilian cities. DDSO levels were previously identified by a latent class analysis based on 13 variables from the discrimination section. An ordinal logistic regression was used to assess associations with these DDSO levels, and weighted ordinal odds ratios (OR) and their respective 95% confidence intervals (95%CI) were estimated using Gile’s estimator. Most participants were young (< 25 years old) black or of mixed-race (pardo), single individuals who had a religious affiliation, primary or incomplete secondary education, and a high and average socioeconomic status. More than half (65%) reported DDSO in the 12 months prior to this study. We observed an independent association among the four latent DDSO classes and the following variables: age < 25 years old (OR = 1.66; 95%CI: 1.21-2.27), white skin color (OR = 1.43; 95%CI: 1.02-2.01), history of sexual (OR = 2.33; 95%CI: 1.58-3.43) and physical violence (OR = 3.08; 95%CI: 2.11-4.49), disclosure of their sexual orientation as MSM to their fathers (OR = 2.00; 95%CI: 1.47-2.72), experienced suicidal ideation in the two weeks prior to this study (OR = 2.09; 95%CI: 1.46-2.98), and use of any illicit drugs in the last six months (OR = 1.61; 95%CI: 1.19-2.18). Our results indicate that contextual factors may contribute to high DDSO levels among MSM in Brazil. Public health policies toward human rights surveillance and protection among MSM must be urgently addressed.

Prevalence and Risks of Depression and Substance Use Among Adults Living with HIV in the Asia-Pacific Region

Despite the mental health and substance use burden among people living with HIV (PLHIV) in the Asia-Pacific, data on their associations with HIV clinical outcomes are limited. This cross-sectional study of PLHIV at five sites assessed depression and substance use using PHQ-9 and ASSIST. Among 864 participants, 88% were male, median age was 39 years, 97% were on ART, 67% had an HIV viral load available and < 1000 copies/mL, 19% had moderate-to-severe depressive symptoms, and 80% had ever used at least one substance. Younger age, lower income, and suboptimal ART adherence were associated with moderate-to-severe depressive symptoms. Moderate-to-high risk substance use, found in 62% of users, was associated with younger age, being male, previous stressors, and suboptimal adherence. Our findings highlight the need for improved access to mental health and substance use services in HIV clinical settings.

Social and structural factors associated with depression and suicidality among men who have sex with men and transgender women in Nepal

INTRODUCTION

The prevalence of depression and suicidality is high among men who have sex with men (MSM) and transgender women (TGW) worldwide. Stigma and discrimination are likely contributing factors. More research is needed in low-income, non-English speaking countries to assess the effects of social and structural factors on depression and suicidality among MSM and TGW.

METHODS

Nepalese MSM and TGW (n = 340) were recruited using a respondent-driven sampling design and filled out a survey questionnaire. The outcomes were depression and suicidality. Data was analyzed using bivariate and multivariable logistic regression.

RESULTS

More than half of the participants (59%) suffered from depression. Severe depression was more common among TGW compared to MSM (41 and 20%, respectively). When it comes to suicidality, TGW had higher lifetime prevalence of suicidal thoughts compared to MSM (32 and 5%, respectively). Depression was positively associated with sex work both for MSM (AOR: 7.9; 95% CI 3.4-18.2) and TGW (AOR: 6.5; 95% CI: 2.3-18.2). MSM who were evicted by family had high odds of suicidal thoughts (AOR: 6.2; 95% CI: 1.3-28.8). For TGW, suicidality was associated with being cheated and threatened (AOR: 3.9; 95% CI: 1.2-12.5) and having forced to marry a female (AOR: 2.2; 95% CI 1.1-5.1).

CONCLUSIONS

Nepalese MSM and TGW suffer from a high degree of mental and psychosocial health issues. Future studies should focus on intervention research and on collecting data from a larger variety of gender and sexual minorities.

The longitudinal association between depression, anxiety symptoms and HIV outcomes, and the modifying effect of alcohol dependence among ART clients with hazardous alcohol use in Vietnam

INTRODUCTION

Mental health disorders may negatively impact HIV outcomes, such as viral suppression (VS) and antiretroviral (ART) adherence among people with HIV (PWH) with hazardous alcohol use. This study evaluates the longitudinal association between depression, anxiety symptoms, VS and complete ART adherence among ART clients with hazardous alcohol use in Vietnam; and examines alcohol dependence as a modifier in this association.

METHODS

This was a secondary data analysis of a trial for hazardous drinking ART clients in Thai Nguyen, Vietnam. From March 2016 to May 2018, 440 ART clients with an Alcohol Use Disorders Identification Test-Concise (AUDIT-C) score ≥4 for men and ≥3 for women were enrolled. Individuals were randomized to either a combined intervention, a brief intervention or a standard of care. Data on sociodemographics, depression, anxiety symptoms, alcohol use, VS and ART adherence were collected at baseline, three, six, and twelve months. Generalized estimating equation models controlling for intervention exposure were used to estimate time-lagged associations. Risk ratios were estimated using Poisson regression with robust variance estimation.

RESULTS

The mean age of participants was 40.2. The majority was male (96.8%), had at least some secondary school education (85.0%) and had a history of injection drug use (80.9%). No overall effect of depression and anxiety symptoms on VS was observed. When stratified by time, increased anxiety symptoms at six months were associated with VS at 12 months (adjusted risk ratio (aRR) = 1.09; 95% CI 1.02 to 1.17). An increase in depression or anxiety symptoms was associated with a decreased probability of complete ART adherence (depression symptoms: aRR = 0.95; 95% CI: 0.91 to 0.99; anxiety symptoms: aRR = 0.93; 85% CI: 0.88 to 0.99). The negative effects of anxiety symptoms on ART adherence were stronger among participants with alcohol dependence, compared to those without.

CONCLUSIONS

Depression and anxiety symptoms had no overall effect on VS, although they were associated with a lower probability of complete ART adherence. Interventions focusing on mental healthcare for PWH with hazardous alcohol use are needed, and integration of mental healthcare and alcohol reduction should be implemented in HIV primary care settings.

Social capital and chemsex initiation in young gay, bisexual, and other men who have sex with men: the pink carpet Y cohort study

Background

Young gay, bisexual, and other men who have sex with men (YMSM) are especially vulnerable to the risks associated with sexualized substance use, or ‘chemsex’. Engaging in chemsex established as a major risk factor for Human Immunodeficiency Virus (HIV) acquisition, and is thus a public health issue of increasing urgency. This paper attempts to explore the association between measures of social capital and patterns of sexualized substance use among a sample of YMSM in Singapore.

Methods

Results of this study were derived from baseline data of the Pink Carpet Y Cohort Study in Singapore, comprising a sample of 570 HIV-negative YMSM aged 18 to 25 years old. Latent class analysis was employed to identify classes with similar patterns of sexualized substance use, and multinomial logistic regression was employed to examine associations between class membership and proxy measures of social capital, including age of sexual debut, bonding and bridging social capital, connectedness to the lesbian, gay, bisexual and transgender community, and outness.

Results

Latent class analysis revealed three classes of YMSM based on their histories of sexualized substance use, which we labelled as ‘alcohol’, ‘poppers’, and ‘chemsex’. Multivariable analyses revealed that participants who were older (aOR = 1.19, p = 0.002) and who identified as gay (aOR = 2.43, p = 0.002) were more likely to be in the poppers class compared to the alcohol class. Participants with a later age of sexual debut were increasingly less likely to be in the poppers (aOR = 0.93, p = 0.039) and chemsex classes (aOR = 0.85, p = 0.018), compared to the alcohol class.

Conclusions

Varying measures of social capital such as an earlier age of exposure to sexual networks may predispose YMSM to greater opportunities for sexualized substance use. Future interventions should target YMSM who become sexually active at an earlier age to reduce the risks associated with sexualized substance use.

Slam Practice: A Review of the Literature

BACKGROUND

Slamming has been developing since 2011 as a new international phenomenon, mostly among men who have sex with men (MSM). It consists of intravenous drug injection before or during planned sexual activity to sustain, enhance, disinhibit, or facilitate the experience. We aimed to synthesize the available published evidence through a systematic literature review in order to precisely describe this phenomenon and to better characterize the population engaging in this practice and its specific motives.

METHODS

A systematic review of the available literature was conducted to identify all relevant publications using PubMed, Psyc-INFO, the Cochrane Library, and ScienceDirect. To complete the review, we followed the recommendations of the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" method. We limited the search to studies published between January 2008 and May 2020.

RESULTS

Our search identified 530 publications, of which 27 were included in the final data synthesis. One study focused on heterosexual and homosexual subpopulations, and all other studies focused on MSM-specific samples. Among MSM, slam prevalence was extremely variable, ranging from 2 to 91%; regarding other sexually active subjects, prevalence ranged from 7 to 14%. The prevalence of HIV-positive subjects varied widely across studies, ranging from 0.6 to 100%. We found less data about hepatitis C virus serostatus, ranging from 3 to 100%. Methamphetamine and mephedrone were the 2 most used drugs.

DISCUSSION/CONCLUSION

The data we found in international literature were very heterogeneous and from poorly reproducible studies. The definition of slamming in the international literature is not always clear, which limits the completeness of the collected data. This topic has been open to studies only recently; however, health professionals must be trained in the management of this practice, considering its risks in the short and medium terms and its addictive potential. We provided and discussed recommendations and potential future directions.

The prevalence of depression in men who have sex with men (MSM) living with HIV: A meta-analysis of comparative and epidemiological studies

BACKGROUND

Men who have sex with men (MSM) living with Human Immunodeficiency Virus (HIV) are more likely to suffer from depressive symptoms (depression hereafter). This is a comprehensive meta-analysis of the prevalence of depression in HIV-infected MSM.

METHODS

Relevant publications were systematically searched in PubMed, PsycINFO, EMBASE, Cochrane Library and Web of Science. Comparative and epidemiological studies with prevalence of depression as measured by the Center for Epidemiological Studies Depression Scale (CES-D) were included. The prevalence of depression was pooled using the random-effects model.

RESULTS

A total of 18 studies with 7653 MSM with HIV and 3395 MSM without HIV were included in the meta-analysis. The pooled prevalence of depression in MSM living with HIV was 43% (95%CI: 32%-53%). Compared to MSM without HIV, MSM living with HIV were more likely to be depressed (OR = 1.46, 1.05-2.03). Subgroup and meta-regression analyses revealed that different CES-D cut-off values and survey year had significant moderating effects on the prevalence of depression.

CONCLUSIONS

Depression was common in MSM living with HIV. Considering the negative effects of depression on health outcomes and wellbeing, regular screening for depression and effective treatment and interventions should be developed for this vulnerable population.

Depressive Emotion Detection and Behavior Analysis of Men Who Have Sex With Men via Social Media

BACKGROUND

A large amount of evidence has indicated an association between depression and HIV risk among men who have sex with men (MSM), but traditional questionnaire-based methods are limited in timely monitoring depressive emotions with large sample sizes. With the development of social media and machine learning techniques, MSM depression can be well monitored in an online and easy-to-use manner. Thereby, we adopt a machine learning algorithm for MSM depressive emotion detection and behavior analysis with online social networking data.

METHODS

A large-scale MSM data set including 664,335 users and over 12 million posts was collected from the most popular MSM-oriented geosocial networking mobile application named Blued. Also, a non-MSM Benchmark data set from Twitter was used. After data preprocessing and feature extraction of these two data sets, a machine learning algorithm named XGBoost was adopted for detecting depressive emotions.

RESULTS

The algorithm shows good performance in the Blued and Twitter data sets. And three extracted features significantly affecting the depressive emotion detection were found, including depressive words, LDA topic words, and post-time distribution. On the one hand, the MSM with depressive emotions published posts with more depressive words, negative words and positive words than the MSM without depressive emotions. On the other hand, in comparison with the non-MSM with depressive emotions, the MSM with depressive emotions showed more significant depressive symptoms, such as insomnia, depressive mood, and suicidal thoughts.

CONCLUSIONS

The online MSM depressive emotion detection using machine learning can provide a proper and easy-to-use way in real-world applications, which help identify high-risk individuals at the early stage of depression for further diagnosis.

Integrating HIV pre-exposure prophylaxis and harm reduction among men who have sex with men and transgender women to address intersecting harms associated with stimulant use: a modelling study

INTRODUCTION

Among men who have sex with men (MSM) and transgender women (TW), stimulant use is high and has been associated with an increased risk of HIV infection, suicide and cardiovascular disease (CVD) mortality. We used epidemic modelling to investigate these intersecting health harms among MSM/TW in Lima, Peru and assess whether they could be mitigated by prioritizing HIV pre-exposure prophylaxis (PrEP) and harm reduction interventions among MSM/TW who use stimulants.

METHODS

We adapted a dynamic model of HIV transmission among MSM/TW in Lima to incorporate stimulant use and increased HIV risk, suicide and CVD mortality. Among 6% to 24% of MSM/TW using stimulants (mostly cocaine), we modelled an increased risk of unprotected anal sex (RR = 1.35 [95%CI: 1.17 to 1.57]) obtained from local data, and increased risk of suicide (SMR = 6.26 [95%CI: 2.84 to 13.80]) and CVD (SMR = 1.83 [95%CI: 0.39 to 8.57]) mortality associated with cocaine use based on a global systematic review. We estimated the proportion of health harms occurring among MSM/TW who use stimulants in the next year (01-2020/01-2021). We also investigated the 10-year impact (01-2020/01-2030) of: (1) PrEP prioritization for stimulant-using MSM/TW compared to random allocation, and (2) integrating PrEP with a theoretical intervention halving stimulant-associated risk.

RESULTS

MSM/TW in Lima will experience high HIV incidence, suicide mortality and CVD mortality (1.6/100 py, and 0.018/100 py, 0.13/100 py respectively) in 2020. Despite stimulant using MSM/TW comprising an estimated 9.5% (95%CI: 7.8 to 11.5) of all MSM/TW, in the next year, 11% 95%CI (i.e. 2.5% to 97.5% percentile) 10% to 13%) of new HIV infections, 39% (95%CI: 18% to 60%) of suicides and 15% (95%CI: 3% to 44%) of CVD deaths could occur among this group. Scaling up PrEP among all stimulant using MSM/TW could prevent 19% (95%CI: 11% to 31%) more HIV infections over 10 years compared to random allocation. Integrating PrEP and an intervention to halve stimulant-associated risks could reduce new HIV infections by 20% (95%CI: 10% to 37%), suicide deaths by 14% (95%CI: 5% to 27%) and CVD deaths by 3% (95%CI: 0% to 16%) over a decade.

CONCLUSIONS

MSM/TW who use stimulants experience a disproportionate burden of health harms. Prioritizing PrEP based on stimulant use, in addition to sexual behaviour/gender identity criteria, could increase its impact. Integrated substance use, harm reduction, mental health and HIV care among MSM/TW is needed.

Sexual Minority Stigma, Sexual Orientation Concealment, Social Support and Depressive Symptoms Among Men Who have Sex with Men in China: A Moderated Mediation Modeling Analysis

Men who have sex with men (MSM) often experience depressive symptoms. However, the potential mechanisms resulting in depressive symptoms are not fully understood. Here, we explore possible mechanisms behind the associations between sexual minority stigma (SMS), sexual orientation concealment (SOC), and social support (SS) with depressive symptoms among MSM. Data (N = 715) used in the study were from the baseline survey of a 3-year cohort study in China. Computer-assisted self-interview was used to collect data. Mediation and moderated mediation modeling analysis were employed to address the question. It was found that SOC partially mediated the association between SMS and depressive symptoms (indirect effect = 0.11, 95% CI 0.05-0.17). SS moderated the mediation model by buffering the path from SMS to SOC (β = 0.17, t = 3.18, P = 0.002). These findings suggested that SS might strengthen the association between SMS and depressive symptoms by moderating the pathway between SMS and SOC.

Does Socio-structural Context Matter? A Multilevel Test of Sexual Minority Stigma and Depressive Symptoms in Four Asia-Pacific Countries

In the Asia-Pacific region, individual sexual stigma contributes to elevated rates of depression among sexual minority men. Less well understood is the role of socio-structural sexual stigma despite evidence that social context influences the experience of stigma. We use data from the United Nations Multi-country Study on Men and Violence to conduct a multilevel test of associations between individual- and cluster unit-level indicators of sexual stigma and depressive symptoms among sexual minority men (n = 562). In the full model, individual-level sexual stigma is not associated with depressive symptoms, although there is significant variation in the association between individual stigma and depressive symptoms across clusters. Contrary to expectation, at the community level, homophobic injunctive norms are negatively associated with depressive symptoms. We discuss the implications for policies, programs, and future research to improve mental health among sexual minority men in the region.

Responding to global stimulant use: challenges and opportunities

We did a global review to synthesise data on the prevalence, harms, and interventions for stimulant use, focusing specifically on the use of cocaine and amphetamines. Modelling estimated the effect of cocaine and amphetamine use on mortality, suicidality, and blood borne virus incidence. The estimated global prevalence of cocaine use was 0·4% and amphetamine use was 0·7%, with dependence affecting 16% of people who used cocaine and 11% of those who used amphetamine. Stimulant use was associated with elevated mortality, increased incidence of HIV and hepatitis C infection, poor mental health (suicidality, psychosis, depression, and violence), and increased risk of cardiovascular events. No effective pharmacotherapies are available that reduce stimulant use, and the available psychosocial interventions (except for contingency management) had a weak overall effect. Generic approaches can address mental health and blood borne virus infection risk if better tailored to mitigate the harms associated with stimulant use. Substantial and sustained investment is needed to develop more effective interventions to reduce stimulant use.

Prevalence and predictors of depressive symptoms among HIV-positive men who inject drugs in Vietnam

Background

HIV infection is common among people who inject drugs (PWID), and HIV-positive PWID may be particularly vulnerable to depression. This study measured the prevalence of depressive symptoms and the factors associated with severe symptoms among 455 HIV-positive PWID in Thai Nguyen, Vietnam.

Methods

We used cross-sectional data from PWID in a randomized controlled trial of an intervention to reduce high-risk injecting and sexual behaviors in Thai Nguyen from 2009–2013. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression Scale (CES-D). We used logistic regression to assess demographic, clinical, and psychosocial predictors of severe depressive symptoms (CES-D≥23) with prevalence odds ratios (POR) and 95% confidence intervals (CI).

Results

The prevalence of severe depressive symptoms (CES-D≥23) was 44%. 25% of participants had mild to moderate depressive symptoms (16≤CES-D<23), and 31% experienced no depressive symptoms (CES-D<16). Not being married, self-rated poor health, greater frequency of injection drug use, history of overdose, no alcohol use, and daily cigarette smoking were positively associated with severe depressive symptoms in unadjusted models and remained predictive in a multivariable model. The strongest predictors of depressive symptoms were self-reported poor health (POR = 2.94, 95% CI: 1.82, 4.76), no current alcohol use (POR = 2.35, 95% CI: 1.47, 3.77), and not currently married or cohabitating (POR = 2.21, 95% CI = 1.40, 3.47).

Conclusion

Severe depressive symptoms were common among HIV-positive PWID in Thai Nguyen and were strongly associated with demographic, clinical, and psychosocial factors. Interventions that promote social support from family and reduce drug dependence may particularly benefit PWID experiencing severe depressive symptoms. Greater recognition and treatment of depressive symptoms has the potential to enhance quality of life and improve HIV clinical outcomes for PWID.
