Abstract
Daily oral pre-exposure prophylaxis (PrEP) is highly effective for HIV prevention, though efficacy depends on adherence. Digital pill systems (DPS) can enable direct, real-time adherence measurement. HIV-negative men who have sex with men (MSM) with substance use (excluding alcohol) utilized a DPS over 90 days and completed weekly surveys reporting sexual activity, condom use, and substance use. Responses indicating (1) any sexual activity and substance use or (2) condomless anal intercourse (CAI) in the prior week were categorized as high risk for HIV acquisition. PrEP adherence data for the 7-day period preceding each response was dichotomized as ≤ 3 and ≥ 4 doses/week, indicating prevention-effective adherence, and compared by HIV risk level. Thirteen MSM were analyzed (median age: 32). Of 113 surveys, 48.7% indicated high HIV risk, with 12.4% reporting CAI alone, 16.8% any sexual activity and substance use, and 19.5% both CAI and substance use. Weekly mean PrEP adherence was 90.3% (6.3 of 7 doses/week), with ≥ 4 doses/week recorded during 92.0% of weeks. The proportion of participants with ≥ 4 recorded doses/week was 88.9% during weeks with CAI alone, 89.5% during weeks with any sexual activity and substance use, 92.0% during weeks with both CAI and substance use, and 92.8% during lower risk weeks. Participants ingested ≥ 4 doses/week during 89.1% of all high-risk weeks and 94.8% of low-risk weeks. Overall, participants maintained high levels of PrEP adherence while engaging in HIV risk behaviors. DPS can be deployed concurrently with data collection tools to assess ingestion patterns during periods of elevated risk.

Abstract
Numerous contextual factors contribute to risky sexual decision-making among men who have sex with men (MSM), with experimental laboratory-based studies suggesting that alcohol consumption, sexual arousal, and partner familiarity have the potential to impact condom negotiations during sexual encounters. The purpose of the current study was to extend this line of inquiry outside of the laboratory and into the everyday lives of MSM. We collected six weeks of daily data on alcohol consumption and sexual behaviors from 257 moderate- and heavy-drinking MSM to examine the within- and between-subjects effects of alcohol consumption, average daily sexual arousal, and partner familiarity on condom negotiation processes during sexual encounters. We hypothesized that alcohol consumption, higher levels of average daily sexual arousal, and greater partner familiarity would all contribute to a reduced likelihood of condom negotiation prior to sexual activity, and that they would also affect the difficulty of negotiations. Contrary to hypotheses, none of these three predictors had significant within-subjects effects on condom negotiation outcomes. However, partner familiarity and average daily sexual arousal did exert significant between-subjects effects on the incidence of negotiation and negotiation difficulty. These findings have important implications for risk-reduction strategies in this population. They also highlight the challenges of reconciling results from experimental laboratory research and experience sampling conducted outside of the laboratory on sexual risk behavior.

Abstract
Stimulant use is an important driver of HIV/STI transmission among men who have sex with men (MSM). Evaluating factors associated with increased stimulant use is critical to inform HIV prevention programming efforts. This study seeks to use machine learning variable selection techniques to determine characteristics associated with increased stimulant use and whether these factors differ by HIV status. Data from a longitudinal cohort of predominantly Black/Latinx MSM in Los Angeles, CA was used. Every 6 months from 8/2014-12/2020, participants underwent STI testing and completed surveys evaluating the following: demographics, substance use, sexual risk behaviors, and last partnership characteristics. Least absolute shrinkage and selection operator (lasso) was used to select variables and create predictive models for an interval increase in self-reported stimulant use across study visits. Mixed-effects logistic regression was then used to describe associations between selected variables and the same outcome. Models were also stratified based on HIV status to evaluate differences in predictors associated with increased stimulant use. Among 2095 study visits from 467 MSM, increased stimulant use was reported at 20.9% (n = 438) visits. Increased stimulant use was positively associated with unstable housing (adjusted [a]OR 1.81; 95% CI 1.27-2.57), STI diagnosis (1.59; 1.14-2.21), transactional sex (2.30; 1.60-3.30), and last partner stimulant use (2.21; 1.62-3.00). Among MSM living with HIV, increased stimulant use was associated with binge drinking, vaping/cigarette use (aOR 1.99; 95% CI 1.36-2.92), and regular use of poppers (2.28; 1.38-3.76). Among HIV-negative MSM, increased stimulant use was associated with participating in group sex while intoxicated (aOR 1.81; 95% CI 1.04-3.18), transactional sex (2.53; 1.40-2.55), and last partner injection drug use (1.96; 1.02-3.74). Our findings demonstrate that lasso can be a useful tool for variable selection and creation of predictive models. These results indicate that risk behaviors associated with increased stimulant use may differ based on HIV status and suggest that co-substance use and partnership contexts should be considered in the development of HIV prevention/treatment interventions.

AIDS Res Ther 2023; 20:32. [PMID: 37268970 DOI: 10.1186/s12981-023-00528-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 05/25/2023] [Indexed: 06/04/2023] Open
Abstract
BACKGROUND Pre-exposure prophylaxis (PrEP) is a proven biomedical strategy to prevent HIV transmission among men who have sex with men (MSM). Despite oral PrEP is safe and effective in MSM, the use of PrEP has been discouraging, especially in high-risk MSM. And there are no relevant studies showing the use of PrEP in high-risk MSM. The purpose of this study was to get the rate of PrEP use and the factors influencing PrEP use among high-risk MSM. METHODS A cross-sectional study was conducted through an electronic questionnaire on the "i guardian Platform", and "snowballing" method was used to recruit MSM in six cities in China, including Beijing, Shenzhen, Chengdu, Changsha, Jinan and Nanjing in China, from January to April 2021. Univariate and multivariate logistic regression analysis were used to analyze the factors associated with the use of PrEP among high-risk MSM who had heard about PrEP. RESULTS Among the 1865 high-risk MSM who had heard of PrEP, the rates of those who were willing to use PrEP, had knowledge awareness of PrEP, and had used PrEP were 96.7%, 24.7%, and 22.4%, respectively. Multivariate logistic regression analysis of PrEP use in high-risk MSM showed that more PrEP was used by those who were 26 years or older (OR = 1.86, 95%CI 1.17 ~ 2.99), had master degree or above (OR = 2.37, 95% CI 1.21 ~ 4.72), had unstable work (OR = 1.86, 95% CI 1.16 ~ 2.96), had tested five or more HIV times in the past year (OR = 3.09, 95% CI 1.65 ~ 6.04), had consulted PrEP (OR = 22.05, 95% CI 14.87 ~ 33.91) and had PrEP knowledge awareness (OR = 1.90, 95% CI 1.41 ~ 2.55) (P < 0.05). CONCLUSIONS The rate of PrEP use in high-risk MSM was relatively low. PrEP was used more by high-risk MSM with unstable jobs, higher education, frequent HIV testing, and PrEP counseling. Public education on PrEP for MSM should continue to be enhanced to help them use PrEP in a timely and accurate manner.

Abstract
Rates of HIV and other sexually transmitted infections (STIs) are high among sexual minority men (SMM). A large body of research has explored determinants of HIV/STI risk behavior, but few studies have explored emotional consequences of these events. Understanding the valence, timing, and strength of emotional reactions to sexual risk could inform use of specific behavior change techniques in interventions (such as anticipated regret) and identify new opportunities for intervention, including just-in-time interventions. We analyzed data from an ecological momentary assessment (EMA) study of 100 HIV-negative/unknown-status SMM to understand patterns of positive affect, negative affect, shame, and stress in the 24 hours after sex. Mixed-effects models showed that the probability of negative affect was higher in the hours following condomless anal sex (CAS) with high-risk partners during which SMM reported being under the influence of alcohol or drugs (A/D involved CAS), versus all other types of sex events (OR = 0.92, SE = 0.03, p = .017). The probability of shame was also higher after A/D-involved CAS, versus other sex events (OR = 1.14, SE = 0.07, p = .035). Findings suggest that the hours following A/D-involved CAS events may be an opportune time to intervene to help SMM avoid similarly aversive experiences in the future.

Abstract
Unlike antiretrovirals for HIV treatment, pre-exposure prophylaxis (PrEP) does not require continual adherence to be fully effective; rather, PrEP adherence is important only in the context of episodes of sexual risk. Therefore, studies of PrEP adherence and persistence must incorporate contemporaneous measurement of sexual behavior. Short, frequent surveys of PrEP use and sexual behavior allow for the measurement of the alignment between PrEP use and sexual behavior. We assessed the feasibility of using biweekly PrEP use and sexual behavior questionnaires to measure adherence and persistence on PrEP over a period of four months. We also measured the alignment of PrEP use and condomless anal sex. PrEP-using MSM in the southern US were recruited using online advertisements. Participants completed a baseline survey followed by brief surveys every two weeks for 16 weeks to report their PrEP use and sexual behavior over the preceding two-week period. Study retention was high: 91% of participants completed the baseline and final survey and, overall, 86% of study surveys were completed. Self-reported PrEP adherence and persistence were high, but instances of PrEP non-adherence were observed to frequently overlap with episodes of condomless anal sex. The most prominent reasons cited for missing PrEP doses were being too busy, not having PrEP on hand, and not being sexually active. Completing short, biweekly surveys of PrEP use and sexual behavior is feasible and acceptable to MSM in the southern US. Future studies should investigate incorporating biomarker measurements to validate self-reported adherence.

Abstract
BACKGROUND AND OBJECTIVES Binge drinking and sexual risk behaviors have historically been associated with lesbian, gay, bisexual, and transgender (LGBT) adults; however, few studies have described this association among broader sexual and gender minority (SGM) students, who often identify outside of LGBT (e.g., asexual, queer). This study examined the relationship between binge drinking and sexual risk behaviors among SGM versus non-SGM college students. METHODS A retrospective analysis was conducted with cross-sectional data from the Spring 2017 American College Health Association-National College Health Assessment (ACHA-NCHA) survey among US undergraduates (n = 47,821) across 92 institutions. Binge drinking was measured as more than five drinks consumed the last time the student socialized; sexual risk behavior was measured as the number of sexual partners in the past 12 months. RESULTS Numerous undergraduates nationally identify as SGM (19.9%), with bisexual (32.7%), other SGM (26.1%), and asexual (25.4%) students comprising the largest subgroups. Prevalent among both SGM (28.1%) and non-SGM (29.6%) students, binge drinking had a significant main effect on the number of sexual partners. A significant interaction effect was observed between SGM identity and binge drinking on the number of sexual partners, such that this association was stronger in SGM versus non-SGM students. This effect remained significant across multiple SGM subgroups. DISCUSSION AND CONCLUSIONS SGM students are more prevalent and diverse than previously reported. While prevalent overall, binge drinking may be uniquely sexualized among SGM students. SCIENTIFIC SIGNIFICANCE In the first large-scale study assessing drinking among disaggregated SGM college students, data suggest tailoring alcohol interventions to SGM students, particularly those identifying outside of LGBT.

Abstract
Although HIV caused one of the worst epidemics since the late twentieth century, China and the U.S. has made substantial progress to control the spread of HIV/AIDS. However, the trends of HIV/AIDS incidence remain unclear in both countries. Therefore, this study aimed to highlight the long-term trends of HIV/AIDS incidence by gender in China and the U.S. population. The data were retrieved from the Global Burden of Disease (GBD) database since it would be helpful to assess the impact/role of designed policies in the control of HIV/AIDS incidence in both countries. The age-period-cohort (APC) model and join-point regression analysis were employed to estimate the age-period-cohort effect and the average annual percentage change (AAPC) on HIV incidence. Between 1994 and 2019, we observed an oscillating trend of the age-standardized incidence rate (ASIR) in China and an increasing ASIR trend in the U.S. Despite the period effect in China declined for both genders after peaked in 2004, the age effect in China grew among the young (from 15–19 to 25–29) and the old age groups (from 65–69 to 75–79). Similarly, the cohort effect increased among those born in the early (from 1924–1928 to 1934–1938) and the latest birth groups (from 1979–1983 to 2004–2009). In the case of the U.S., the age effect declined after it peaked in the 25–29 age group. People born in recent birth groups had a higher cohort effect than those born in early groups. In both countries, women were less infected by HIV than men. Therefore, besides effective strategies and awareness essential to protect the young age groups from HIV risk factors, the Chinese government should pay attention to the elderly who lacked family support and were exposed to HIV risk factors.

Abstract
BACKGROUND Ecological momentary assessment (EMA) is a research design that allows for the measurement of nearly instantaneous experiences within the participant's natural environment. Using EMA can help improve recall bias, ecological validity, and patient engagement while enhancing personalization and the ubiquity of interventions. People that can benefit from the use of EMA are men who have sex with men (MSM). Previous EMA studies have been successful in capturing patterns of depression, anxiety, substance use, and risky sexual behavior. These findings are directly relevant to MSM, who have high rates of each of these psychological and behavioral outcomes. Although there is a driving force behind the growing literature surrounding EMAs among MSM, no synthesizing reviews yet exist. OBJECTIVE The aims of this study were to (1) synthesize the literature across fields on how EMA methods have been used among MSM, (2) better understand the feasibility and acceptability of EMA interventions among MSM, and (3) inform designs for future research studies on best evidence-based practices for EMA interventions. METHODS Based on 4 library databases, we conducted a scoping review of EMAs used within interventions among MSM. The eligibility criteria included peer-reviewed studies conducted in the United States and the use of EMA methodology in an intervention for MSM. Modeling after the Centers for Disease Control and Prevention's Compendium of Evidence-Based Interventions as the framework, we applied a typology that used 8 distinct review criteria, for example, sample size, design of the intervention, random assignment, design of the follow-up investigation, rate of retention, and rate of engagement. RESULTS Our results (k=15, N=952) indicated a range of sample sizes; the smallest sample size was 12, while the largest sample size was 120. Of the 15 studies, 7 (47%) focused on outcomes related to substance use or outcomes related to psychological experiences. Of the 15 studies, 5 (33%) implemented an EMA intervention across 30 days. Of the 15 studies, 2 studies (13%) used random assignment, and 2 studies (13%) had quasi-experimental designs. Of the 15 studies, 10 studies (67%) reported acceptable retention rates greater than 70%. The outcomes that had event-contingent prompts (ie, prompts after engaging in substance use) were not as effective in engaging participants, with overall engagement rates as low as 37%. CONCLUSIONS Our systematic scoping review indicates strong evidence that the EMA methodology is both feasible and acceptable at high rates among MSM, especially, when examining psychological and behavioral outcomes such as negative or positive affect, risky sexual behavior, or substance use. Further research on optimal designs of EMA interventions for MSM is warranted.

Abstract
BACKGROUND Seroadaptive behaviors refer to a wide range of harm reduction practices to decrease HIV transmission risk. Effective implementation of seroadaptive behaviors is dependent on knowledge of one's own serostatus and that of one's sexual partners. Partner-level and environmental-level attributes may affect seroadaptation practices. We assessed factors associated with seroadaptive behaviors. METHODS Men who have sex with men and transgender women were recruited from an HIV pre-exposure prophylaxis clinical trial (iPrEx) with study sites in the US, Peru, Ecuador, Brazil, Thailand, and South Africa. Partnership-level data were collected at the baseline visit for the 3 most recent partners. Participants were considered to have practiced seroadaptive behaviors if: (1) they believed their partner to be HIV-negative, that is, serosorting; or (2) no condomless receptive sex occurred with an HIV-positive or unknown status partner, that is, seropositioning. RESULTS Of 2331 participants, 41% always practiced seroadaptive behaviors, 36% sometimes did, and 23% never did. Participants enrolled at study sites in the US (P < 0.001) and Peru/Ecuador (P < 0.001) were more likely to practice seroadaptive behaviors, whereas transgender women were less likely to do so (P < 0.001). Seroadaptive behaviors were more likely to occur in relationships with steady partners (P = 0.005) and emotionally close relationships (P = 0.013). CONCLUSIONS Seroadaptive behaviors were more frequently observed among iPrEx participants from the US, Peru, and Ecuador study sites and among participants in relationships with partners who they were more committed to and felt emotionally close to. Our findings suggest that seroadaptive behaviors may be influenced by social norms that vary geographically and culturally.

Abstract
This is a cross-sectional study based on an open web survey with the primary objective to assess associations between the use of apps for seeking sex partners and vulnerabilities related to human immunodeficiency virus (HIV) acquisition among men who have sex with men (MSM) in Brazil. Participants were recruited to the study through ads posted in social media such as Twitter, Facebook, and WhatsApp. Consenting respondents completed a questionnaire on demographics, history of sexually transmitted infections (STIs), and risk behaviors and perceptions, including calculation of the Risk Behavior Score for HIV infection proposed by Rocha et al. Among the 859 participants, 714 (83.1%) reported they used apps for seeking sex partners. Use of apps for seeking sex partners was associated with high-risk behavior for HIV infection, self-reported syphilis, self-perception of HIV risk, and use of marijuana. The use of apps for seeking sex partners has rapidly become the norm for MSM in Brazil. The associations with STIs and risk behaviors should be seen as an opening to improve public health, presenting opportunities to promote knowledge, safer sex practices, and referral to HIV/STI screening and prevention interventions.

Oral sex practices among men who have sex with men and transgender women at risk for and living with HIV in Nigeria. PLoS One 2020; 15:e0238745. [PMID: 32886722 PMCID: PMC7473579 DOI: 10.1371/journal.pone.0238745] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Accepted: 08/21/2020] [Indexed: 12/15/2022] Open
Abstract
Background Men who have sex with men (MSM) and transgender women (TGW) are at risk for sexually transmitted infections (STIs), including those of the oropharynx. We estimated the prevalence and factors associated with oral sex practices and characterized oropharyngeal STIs among a cohort of MSM and TGW in Nigeria. Methods From 2013 to 2018, TRUST/RV368 recruited MSM and TGW into HIV/STI diagnosis and treatment at community-based clinics in Nigeria. Participants who completed HIV testing and oral sex questions at enrollment were selected. Cross-sectional analyses with bivariate and multivariable logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs). Oropharyngeal swab testing for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) began in 2014 and for those with diagnostic results at enrollment, the unadjusted association of oral sex practices with oropharyngeal STIs was conducted. Results A total of 1342 participants had a median age of 25 years (interquartile range: 22–29), 58% were living with HIV, and 69% reported oral sex practices. Factors associated with increased odds of engaging in oral sex included living with HIV (adjusted [a]OR: 1.4, 95% CI: 1.1–1.8), self-identifying as a woman (aOR:1.8, 95% CI: 1.1–2.8), mobile phone ownership (aOR:2.3, 95% CI: 1.3–3.9), receptive anal sex (aOR:1.7, 95% CI:1.3–2.3) and multiple male sexual partners (2 to 4 vs. ≤1, aOR:1.5, 95% CI: 1.0–2.2; 5+ vs ≤1, aOR:2.9, 95% CI:1.9–4.3). Oropharyngeal STI prevalence was 7% (52/752) and higher among those who engaged in oral sex compared to those who did not (unadjusted OR: 2.5, 95% CI:1.2–5.3). Conclusions Oral sex was common and associated with an increased odds of oropharyngeal STIs among MSM and TGW from Nigeria. In the absence of screening and treatment guidelines, condoms continue to be the mainstay for oral STI prevention. A pre-exposure prophylaxis for bacterial STIs would complement current prevention strategies to curb transmission.
