Surveillance Among Men Who have Sex with Men in the United States: A Comparison of Web-Based and Venue-Based Samples

Nested case-control study investigating factors affecting initial adoption of HIV self-testing among men who have sex with men in Guangzhou, China: amidst comprehensive service coverage

Background

China has been exploring HIV self-testing (HIVST) among men who have sex with men (MSM) since 2014. Currently, both non-profit and commercial initiatives HIVST services have achieved comprehensive coverage. Investigating the factors influencing the initial adoption of HIVST among MSM in this context can help develop tailored HIVST service strategies of and further promote HIVST adoption among MSM communities.

Methods

We selected 230 participants from a prospective cohort on HIV infection among MSM population in Guangzhou, China, who had no prior experience of HIVST. Among the study participants, 43 who initially adopted HIVST during the follow-up period were designated as the case group, while the rest comprised the control group. Electronic questionnaires were used for baseline and follow-up surveys to collect demographic information, sexual behavior characteristics and HIVST utilization in the past 6 months. Logistic regression models were applied to analyze the factors influencing the initial adoption of HIVST.

Results

Among the study participants, 18.7% (43/230) initially adopted HIVST during the follow-up period. Multivariate logistic regression analysis revealed that individuals who primarily sought sexual partners through offline venues in the past 6 months (aOR = 5.28, 95% CI: 1.01-27.79), had more than one sexual partner in the past 6 months (aOR = 2.76, 95% CI: 1.33-5.74), engaged with more than two casual partners in the past 6 months (aOR = 3.02, 95% CI: 1.35-6.78), or had more than one regular partner (aOR = 3.37, 95% CI: 1.51-7.51) exhibited an increased likelihood of initiating HIVST.

Conclusion

In the context of comprehensive promotion and coverage of HIVST service, the development of personalized, adaptable, and innovative HIVST strategies for MSM with a higher number of sexual partners, particularly those in regular partnerships and those seeking partners offline, may further increase the adoption of HIVST among MSM.

Chemsex Drug Use among a National Sample of Sexually Active Men who have Sex with Men, - American Men's Internet Survey, 2017-2020

Background: Chemsex is the intentional use of drugs to enhance sexual activity. Chemsex drug use among men who have sex with men (MSM) is associated with sexual behaviors that increase sexually transmitted infection (STI) risks and adverse mental health outcomes. However, published data are largely based on MSM recruited from STI clinics. There are limited data about use of chemsex drugs among national samples of MSM in the United States. Using data from the American Men's Internet Survey (AMIS), we assessed the prevalence and correlates of use of chemsex drugs among sexually active MSM in the United States. Methods: We used data from the 2017 to 2020 AMIS cycles to examine the prevalence of chemsex drug use in the past 12 months among MSM. We calculated prevalence ratios (PR) and 95% confidence intervals (CI) to compare chemsex drug use across demographic, behavioral, and mental health factors. Results: Of 30,294 MSM, 3,113 (10.3%) reported chemsex drug use in the past 12 months. Of the 3,113 MSM who reported chemsex drug use, 65.1% reported ecstasy use, 42.5% reported crystal methamphetamine use, and 21.7% reported GHB use. Factors associated with chemsex drug use included condomless anal sex (PR = 1.93, 95%=1.69-2.20), problem drinking (PR = 2.36, 95% = 2.13-2.61), bacterial STI test (1.84, 95% CI = 1.68-2.02) and probable serious mental illness (PR = 1.92, 95% = 1.76-2.09). Conclusion: Chemsex drug use is associated with behaviors that increase STI risk and mental distress among MSM. Health programs that serve MSM can consider screening for chemsex drug use and offering sexual and mental health promotion and risk reduction interventions when necessary.

How Black and Latino young men who have sex with men in the United States experience and engage with eligibility criteria and recruitment practices: implications for the sustainability of community-based research

Research recruitment, eligibility, and who chooses to participate shape the resulting data and knowledge, which together inform interventions, treatment, and programming. Patterns of research participation are particularly salient at this moment given emerging biomedical prevention paradigms. This paper explores the perspectives of Black and Latino young men who have sex with men (BL-YMSM) regarding research recruitment and eligibility criteria, how their experiences influence willingness to enroll in a given study, and implications for the veracity and representativeness of resulting data. We examine inclusion and recruitment as a complex assemblage, which should not be reduced to its parts. From April-July 2018, we conducted in-depth interviews with 30 BL-YMSM, ages 18-29, in New York City. Interviews were recorded, transcribed, and analyzed using the constant comparative method. Black and Latino YMSM's responses unveiled tensions between researchers', recruiters', and participants' expectations, particularly regarding eligibility criteria (e.g., age, sex frequency), assumptions about 'risky behaviors,' and the 'target' community. Men preferred peer-to-peer recruitment, noting that most approaches miss key population segments. Findings highlight the need to critically examine the selected 'target' community, who sees themselves as participants, and implications for data comprehensiveness and veracity. Study eligibility criteria and recruitment approaches are methodological issues that shape knowledge production and the policies and programs deployed into communities. These findings can inform how future research studies frame recruitment and eligibility in order to better meet the needs of participants and ensure future engagement.

"They know what they are getting into:" Researchers confront the benefits and challenges of online recruitment for HIV research

Online research has become a critical recruitment modality for understanding and reducing health disparities among hidden populations most at risk for HIV infection. There is a lack of consensus and guidelines for the responsible conduct of online recruitment for HIV risk populations. Using semi-structured phone interviews, this study drew on the experiences of principal investigators (PIs) engaged in online HIV research to illuminate scientific and ethical benefits and challenges of social media recruitment. Using Thematic Analysis five major themes emerged: sampling advantages and disadvantages; challenges of data integrity; control of privacy protections; researcher competence and responsibility; and resources.

Pre-exposure Prophylaxis Use Among Men Who Have Sex with Men Experiencing Partner Violence

Intimate partner violence (IPV) significantly increases HIV risk among MSM. Pre-exposure prophylaxis (PrEP) may provide MSM experiencing IPV an option for self-protection from HIV without requiring condom negotiation or compromising safety. This study examined relationships among various forms of IPV (physical, emotional, monitoring, controlling, and forced sex) and PrEP use among 863 MSM participating in a cross-sectional, internet-based survey. Participants reported IPV rates during the prior 6 months that were consistent with prior research (physical violence, 23.3%; emotional violence, 36.3%; monitoring, 45.1%; controlling, 25.3%; forced sex, 20.0%). Forced sex and emotional IPV were negatively associated with PrEP use in our sample; in contrast, controlling was positively associated with PrEP use. We suggest clinical IPV screenings among MSM seeking PrEP, as well as PrEP-focused interventions that explicitly address IPV.

Gaps in Sexually Transmitted Infection Screening among Men who Have Sex with Men in PrEP Care in the United States

BACKGROUND

The U.S. Centers for Disease Control and Prevention (CDC) recommends comprehensive sexually transmitted infection (STI) screening every 3-6 months for men who have sex with men (MSM) using HIV preexposure prophylaxis (PrEP). The gaps between these recommendations and clinical practice by region have not been quantified.

METHODS

We used survey data collected from the internet-based ARTnet study between 2017 and 2019 on STI screening among MSM across the U.S., stratified by current, prior, and never PrEP use. Poisson regression models with robust error variance were used to model factors, including residence in the Southeast, associated with consistent ("always" or "sometimes") exposure site-specific STI screening during PrEP care.

RESULTS

Of 3259 HIV-negative MSM, 19% were currently using PrEP, 6% had used PrEP in the past, and 75% had never used PrEP. Among ever PrEP users, 87%, 78%, 57%, and 64% reported consistent screening for STIs by blood sample, urine sample or urethral swab, rectal swab, or pharyngeal swab, respectively, during PrEP care. Compared to PrEP users in all other regions, PrEP users in the Southeast were significantly less likely to be consistently screened for urogenital (adjusted prevalence ratio [aPR], 0.86; 95% confidence interval [CI], 0.76-0.98) and rectal STIs (aPR, 0.76; 95% CI, 0.62-0.93) during PrEP care.

CONCLUSIONS

Substantial gaps exist between CDC recommendations for STI screening during PrEP care and current clinical practice, particularly for rectal and pharyngeal exposure sites that can harbor asymptomatic infections and for MSM in Southeast states where the STI burden is substantial.
