Internalized Homonegativity and Substance Use Among U.S. Men Who Have Sex with Men Only (MSMO) and Men Who Have Sex with Men and Women (MSMW)

Prevalence and Predictors of Psychoactive Drug Use among Chinese Men Who Have Sex with Men: A Longitudinal and Mediation Study

Few longitudinal studies have examined the prevalence of psychoactive drug use and its related predictors among Chinese men who have sex with men (MSM) in Hong Kong. This longitudinal study aimed to investigate the prevalence of psychoactive drug use in this population and the relationships of background characteristics, health status, MSM-related self-stigma, and perceived stress with psychoactive drug use. Furthermore, the study tested the mediation effect of perceived stress in the relationship between MSM-related self-stigma and psychoactive drug use based on the minority stress model and the general strain model. A total of 600 MSM were recruited through multiple sources and completed a telephone interview at baseline, and 407 completed the 6-month follow-up survey. Prevalence of using any type of psychoactive drugs in the past 12 months at baseline and in the past six months at follow-up was 16.8% and 9.1% respectively. History of sexually transmitted infection (STI), self-stigma and perceived stress significantly predicted psychoactive drug use at 6-month follow-up. Bootstrapping analysis showed that self-stigma could, directly and indirectly, predict psychoactive drug use at 6-month follow-up through perceived stress. The results highlighted the need for interventions to reduce psychoactive drug use among local MSM and its potential modifiable factors.

Development and validation of a risk score for predicting inconsistent condom use with women among men who have sex with men and women

BACKGROUND

Men who have sex with men and women (MSMW) are the most important bridge population for HIV transmission. Condom use plays an important role for HIV infection. However the predictors for condom ues with females are not well characterized.

METHODS

This was a cross-sectional study. Participants were enrolled by four community-based organizations (CBOs) by offline (bathrooms, bars), and online (gay applications, chat room) from April to December 2019. Electronic questionnare was fulfilled after a face-to-face training led by CBOs. We identified predictors of inconsistent condom use with females by creating a risk score based on regression coefficients. We externally validated this score via an independent cross-sectional survey conducted in Zhejiang Province in 2021. A total of 917, 615 MSMW were included in analysis in 2019 and 2021, seperately.

RESULTS

Among 917 MSMW, 73.2% reported heterosexual behavior in the prior 6 months and 38.3% reported inconsistent condom use with females (ICUF) over that time. Compared with heterosexual/unsure MSMW, bisexual MSMW reported more male and female sex partners, higher proportion of inconsistent condom use with males, less commercial sex with males (p < 0.05). Four risky predictors of ICUF were identified: Duration of local residence ≦6 months; more than one male partner in the prior 6 months; inconsistent condom use with males in the prior 6 months; and never heard post-exposure prophylaxis (PEP). The proportions of respondents indicating ICUF in the low- (0), medium- (2-4) and high-risk (6-20) groups (according to our risk scoring system) were 11.7% (14/120), 26.9% (96/357), and 78.1% (125/160), respectively (P_trend < 0.001). In the validation survey, the respective proportions of those reporting ICUF were 13.4% (15/112), 17.8% (24/185) and 87.3% (96/110) (P_trend < 0.001).

CONCLUSIONS

We developed and validated a predictive risk score for ICUF among MSMW; four factors were identified, of which inconsistent condom use with men was the most important. Risk reduction intervention programs should focus on MSM who report inconsistent condom use with males, never heard PEP, having multiple partners and living in local less than 6 months.

Disparities in alcohol use and heavy episodic drinking among bisexual people: A systematic review, meta-analysis, and meta-regression

BACKGROUND

Alcohol consumption is more prevalent among sexual minorities than among heterosexuals; however, differences between minority sexual orientation groups are understudied. This systematic review and meta-analysis aimed to summarize existing evidence on the prevalence of alcohol use among bisexual people compared to their lesbian/gay and heterosexual counterparts.

METHODS

A systematic review of literature from 1995 to May 2020 was performed using Medline, PsycInfo, and Embase (OVID), Scopus, CINHAL and LGBT Life (EBSCO), combining keywords for bisexuality and alcohol use. Peer-reviewed publications that reported quantitative data on alcohol use among bisexual people were included. A random-effects model was used to pool the prevalence of two outcomes: any alcohol use and heavy episodic drinking (HED). Subgroup analysis and random-effects meta-regression were used to explore heterogeneity.

RESULTS

Of 105 studies eligible for data extraction, the overall prevalence of alcohol use was higher among bisexuals compared to lesbian/gay and heterosexual people. For example, the prevalence of past-month HED was 30.0% (28.2, 31.8) among bisexual people versus 25.5% (23.8, 27.2) among lesbian/gay and 21.3% (19.6, 23.0) among heterosexual individuals. Pooled odds ratio estimates showed that bisexual people were more likely to report alcohol use and HED compared to their counterparts. Gender was a significant effect modifier in meta-regression analysis, with greater disparities among women than among men.

CONCLUSIONS

These results highlight the need for additional research to understand factors underlying bisexual people's greater risk, and particularly bisexual women, as well as alcohol use interventions that are targeted towards the specific needs of bisexual people.

Correlates of Homonegativity Towards Men Who Have Sex With Men Among Black Individuals in the United States

This study aims to identify the factors that are associated with homonegativity toward men who have sex with men (MSM) within Black communities since the expansion of LGBTQ rights. A survey was completed in 2016 by a nationally representative sample of 868 Black respondents, 18-50 years old, via e-mail. Demographics, perception of same-gender sexual behaviors, religiosity, experienced racism, and contact with the carceral system (CS) were assessed. 61.6% of respondents endorsed at least one homonegative belief. Being male, residing in the South, attending religious services, receiving homonegative faith messaging, and having contact with the CS were significantly associated with homonegativity toward MSM while experiencing racism, older age, and residing in a non-metropolitan area were not. Education efforts on LGBTQ identities in Black communities should engage faith communities, extend to metropolitan and non-metropolitan areas of the South, and include younger and older adults. Programs that decrease the arrest of Black individuals may also help reduce homonegativity toward MSM.

Measure of Internalized Sexual Stigma for Lesbians and Gay Men (MISS-LG) in Taiwan: Psychometric Evidence from Rasch and Confirmatory Factor Analysis

Internalized sexual stigma may hamper the development of self-identity, social interaction, and intimate relationship in lesbian, gay, and bisexual (LGB) individuals. The Measure of Internalized Sexual Stigma for Lesbians and Gay Men (MISS-LG) is an important instrument assessing internalized sexual stigma for LGB individuals. However, its psychometric properties have not been examined in LGB populations outside the Italian community. The present study used advanced psychometric testing to evaluate the traditional Chinese version (the MISS-LG) among LGB individuals in Taiwan. LGB individuals (500 male, 500 female) participated in this study and completed the MISS-LG, HIV and Homosexuality Related Stigma (HHRS), and Acceptance and Action Questionnaire-II (AAQ). Confirmatory factor analysis results confirmed the three-factor structure of the MISS-LG; however, two items for males and one item for females had somewhat low factor loadings on the sexuality factor. Each MISS-LG factor was found to be unidimensional in Rasch results, except for the slight misfit in Item 3 and concurrent validity of the MISS-LG was supported by the positive correlations with HHRS and the AAQ. The Chinese MISS-LG has relatively satisfactory psychometric properties. However, further research is needed to investigate the reasons for problematic fitting of several items.

Translation and validation in Brazilian Portuguese of the reactions to homosexuality scale

Internalized homonegativity results from the acceptance of negative attitudes about one's same-sex orientation, which has negative consequences for the health of gay, bisexual and other men who have sex with men (GBM). We translated the 7-item Reactions to Homosexuality Scale (RHS) to Brazilian Portuguese and assessed its factor structure, validity and reliability. The first step included the translation, back-translation, evaluation, peer review, and pre-testing of the scale. Then, we piloted the scale in two convenience samples of adult Brazilians recruited online during October 2019 and February to March 2020 through advertisements on Grindr and Hornet, respectively. The largest sample was randomly split into two groups for exploratory factor analysis (EFA) then confirmatory factor analysis (CFA). Criterion and construct validity were assessed via correlations between scale scores and study variables. A total of 5573 GBM (sample 1: 218; sample 2: 5355) completed the RHS. EFA (N = 2652) yielded two eigenvalues greater than one (Factor 1: 3.5 and Factor 2: 1.1). A one-factor solution provided the most interpretable model based on examination of scree plot and item factor loadings (χ2(14) = 1373.1, p < 0.001; CFI = 0.89; TLI = 0.84; RMSEA = 0.19; SRMS = 0.09). Though one-factor CFA showed moderate fit, freeing errors terms to covary, based on item content and interpretation, significantly improved model fit (χ2(12) = 309.1, p < .001; CFI = 0.97; TLI = 0.96; RMSEA = 0.09; SRMR = 0.02). As hypothesized, men who did not self-identify as gay (mean score 17.9 compared to those self-identifying as gay: 11.8) and men who reported no sex with men in the past 6 months (mean score 12.6 compared to those who reported sex with men: 10.6) scored higher reflecting higher internalized homonegativity. The RHS was effectively translated and validated in Brazilian Portuguese and can be used to evaluate the role of internalized homonegativity on GBM's health, as well as its impact on the uptake of HIV prevention technologies.

Ecological and Syndemic Predictors of Drug Use During Sex and Transactional Sex among U.S. Black Men Who Have Sex with Men: A Secondary Data Analysis from the HPTN 061 Study

Threats to sexual health among U.S. Black men who have sex with men (MSM) may manifest in a context of social adverse experiences. Situational sex is one such context, which we characterize as sexual behaviors driven either by a desire to cultivate a specific sexual experience or attributable to social vulnerability. Two characterizations of situational sex explored in this study were drug use during sex and transactional sex. Guided by ecological and syndemic frameworks, we conducted a secondary data analysis of social conditions and sexual behaviors among a prospective cohort of Black MSM from the HIV Prevention Trial Network (HPTN) 061 study. Using structural equation modeling, this analysis examined the indirect effect of syndemic factors (substance use, depression, violence exposure) in the relationship between ecological constructs (anti-Black/homophobic stigma, childhood violence, and economic vulnerability) and situational sex (drug use during sex, transactional sex). Model fit indices, CFI (.870) and SRMR (.091), demonstrated reasonable fit. Significant indirect effects emerged via substance use for economic vulnerability (indirect effect = .181, 95% CI [.078, .294]) and anti-Black/homophobic violence and stigma (indirect effect = .061, 95% CI [.008, .121]) on drug use during sex; as well as on transactional sex (economic vulnerability indirect effect = .059, 95% CI [.018, .121] and anti-Black/homophobic stigma and violence indirect effect = .020, 95% CI [.003, .051]). Findings implicate the need for social and fiscal intervention to address upstream, ecological, and syndemic factors that influence inherent vulnerability of situational sex and overall threats to sexual health among Black MSM.

Classes of Sexual Identity, Homophobia, and Sexual Risk among Black Sexual Minorities in HPTN 061

Homophobia is associated with sexual risk among sexual minorities, including Black sexual minority men, though experienced homophobia may differ across sexual identities. We conducted latent class analysis of sexual identities and experienced homophobia associated with sexual risk, and tested mediators of this association. We used longitudinal data from the HIV Prevention Trials Network Study 061 (n = 1,553). We generated rate ratios between baseline latent classes of experienced homophobia and sexual identity and 12-month outcomes: Condomless receptive anal intercourse (CRAI), number of partners, and transactional sex. Mediators included 6-month internalized homophobia, depression, social support, and substance use. We selected the following 7-class model: "Bisexual, rare homophobia" (reference), "Mixed identities, mixed homophobia", "Bisexual, frequent homophobia", "Heterosexual/Same-gender loving, frequent homophobia", "Gay, frequent homophobia", " Gay/Same-gender loving, frequent homophobia," and "Gay, rare homophobia." All other classes had greater CRAI than the reference. For bisexual/mixed/heterosexual classes, approximately 20% of this association was positively mediated through our mediators (p < .05). The Heterosexual/Same-gender loving class had the largest proportion mediated through internalized homophobia. For gay-identifying classes, mediation was marginally significant (.05 < p < .10). Classes of sexual identity and experienced homophobia were associated with CRAI among Black sexual minority men, partially mediated through internalized homophobia, depression, social support, and substance use.

Syndemic latent transition analysis in the HPTN 061 cohort: Prospective interactions between trauma, mental health, social support, and substance use

BACKGROUND

Substance use among Black sexual minority men (BSMM) is a significant public health focus of prevention interventions due to its association with sexual risk behaviors and transmission of HIV. Traumatic experiences and mental health challenges may interact to create a syndemic associated with substance use in this population; this may be moderated by social support however.

METHODS

Using a multicenter prospective cohort of 1068 BSMM, we conducted a longitudinal syndemic latent transition analysis testing whether baseline and 6-month race and sexuality-targeted violence, intimate partner violence, other traumatic experiences, depression, and internalized homophobia was associated with 12-month substance use. We also tested if social support modified this and was associated with transitions between statuses.

RESULTS

Our analysis identified four statuses: A "low-risk" status characterized by the lowest proportions of syndemic factors, and 3 "high-risk" statuses, characterized by higher proportions of syndemic factors. All three high-risk statuses were associated with higher substance use than the low-risk status, with the greatest association observed with "high-risk status C" (aRR = 4.54, 95 % CI 1.98, 10.40). Social support attenuated this association (Interaction aRR = 0.21, 95 % CI 0.05, 0.85) and was associated with lower transition rates from low to high-risk status 6 months later (Transition ratio = 0.45, 95 % CI 0.29, 0.69).

CONCLUSIONS

Our findings identified a syndemic of trauma, depression, and homophobia among BSMM associated with substance use, but attenuated by social support. Future research into the role of social support and resiliency in substance use prevention and recovery is recommended.
