A Mixed Methods Investigation Examining the PrEP Cascade Among 13-18-Year-Old Latino Adolescent Sexual Minority Men.

Latino adolescent sexual minority men (ASMM) are at high risk of HIV. Limited research has explored the impact of parent-adolescent communication and beliefs on PrEP adoption among Latino ASMM. Our objective was to examine how parental support and beliefs influence decisions regarding PrEP use. We analyzed PrEP-related attitudes and behaviors within a national cohort of 524 Latino ASMM aged 13-18. Out of the participants, 60.5% were suitable for PrEP. Among them, 59.7% were in the precontemplation stage (stage 1), indicating a lack of willingness or belief of unsuitability. However, 86.4% moved to reach the contemplation stage (stage 2), demonstrating willingness and suitability for PrEP. Only 16.8% moved on to the PrEParation stage (stage 3), indicating their intention to start using PrEP. Furthermore, 4.3% progressed to the PrEP action stage and initiation (stage 4), signifying they had received a prescription, and all reported high adherence (stage 5). Factors associated with reaching later stages included older age, parental support of sexual orientation, and previous HIV/STI testing. The qualitative findings revealed diverse attitudes towards parental involvement in PrEP care among Latino ASMM, including positive, negative, and ambivalent perspectives. Notably, Spanish-speaking participants expressed specific barriers to PrEP communication between ASMM and their parents. Given that parental support and attitudes emerged as significant factors in both our quantitative and qualitative findings, it is evident that public health approaches aiming to disseminate education and awareness about PrEP to parents and families could alleviate the burden on adolescents to educate their parents and enhance support.

Establishing evidence criteria for implementation strategies in the US: a Delphi study for HIV services.

BACKGROUND: There are no criteria specifically for evaluating the quality of implementation research and recommending implementation strategies likely to have impact to practitioners. We describe the development and application of the Best Practices Tool, a set of criteria to evaluate the evidence supporting HIV-specific implementation strategies. METHODS: We developed the Best Practices Tool from 2022-2023 in three phases. (1) We developed a draft tool and criteria based on a literature review and key informant interviews. We purposively selected and recruited by email interview participants representing a mix of expertise in HIV service delivery, quality improvement, and implementation science. (2) The tool was then informed and revised through two e-Delphi rounds using a survey delivered online through Qualtrics. The first and second round Delphi surveys consisted of 71 and 52 open and close-ended questions, respectively, asking participants to evaluate, confirm, and make suggestions on different aspects of the rubric. After each survey round, data were analyzed and synthesized as appropriate; and the tool and criteria were revised. (3) We then applied the tool to a set of research studies assessing implementation strategies designed to promote the adoption and uptake of evidence-based HIV interventions to assess reliable application of the tool and criteria. RESULTS: Our initial literature review yielded existing tools for evaluating intervention-level evidence. For a strategy-level tool, additions emerged from interviews, for example, a need to consider the context and specification of strategies. Revisions were made after both Delphi rounds resulting in the confirmation of five evaluation domains - research design, implementation outcomes, limitations and rigor, strategy specification, and equity - and four evidence levels - best, promising, more evidence needed, and harmful. For most domains, criteria were specified at each evidence level. After an initial pilot round to develop an application process and provide training, we achieved 98% reliability when applying the criteria to 18 implementation strategies. CONCLUSIONS: We developed a tool to evaluate the evidence supporting implementation strategies for HIV services. Although specific to HIV in the US, this tool is adaptable for evaluating strategies in other health areas.

Pre-exposure prophylaxis (PrEP) among people who use drugs: a qualitative scoping review of implementation determinants and change methods.

Implementation of pre-exposure prophylaxis (PrEP) to prevent HIV transmission is suboptimal in the United States, particularly among people who use drugs (PWUD). PrEP research among PWUD is scarce, and the factors that impact implementation are largely unknown. Therefore, we conducted a scoping review of implementation determinants (i.e., barriers and facilitators), as well as the change methods (implementation strategies and adjunctive interventions) that have been evaluated to increase PrEP implementation and use among PWUD. We identified 32 peer-reviewed articles assessing determinants and five that evaluated change methods. Determinants were coded using the updated Consolidated Framework for Implementation Research (CFIR), which is an established framework to understand the multilevel barriers and facilitators associated with implementation. Findings indicate that most research was conducted among PrEP recipients (i.e., patients), focusing on awareness and willingness to use PrEP, with less focus on factors impacting clinicians and service delivery systems. Moreover, very few change methods have been evaluated to improve clinician adoption and adherence to CDC guidelines for PrEP provision and/or recipient uptake and adherence to PrEP. Future research is needed that focuses on factors impacting implementation from a clinician standpoint as well as innovative change methods to increase PrEP awareness, reach, adoption, and sustained adherence to guidelines. Implementation Science offers a wealth of knowledge to speed up the effort to end the HIV epidemic in the United States.

Doomscrolling: Prospective associations between daily COVID news exposure, internalizing symptoms, and substance use among sexual and gender minority individuals assigned female at birth.

Cross-sectional studies have demonstrated associations between COVID news exposure, anxiety, and depression. However, longitudinal research examining the directionality of these associations is extremely limited. Further, most studies have focused on the general population and neglected sexual and gender minority individuals (SGM), a population disproportionately impacted by the pandemic. To address these limitations, the current study utilized data from a 30-day diary study of SGM assigned female at birth (N = 429). We examined concurrent and prospective associations between COVID news exposure, depressed and anxious affect, COVID distress, substance use, and motives for use. Further, we examined associations between cumulative COVID news exposure across the diary period and prospective changes in anxiety, depression, and COVID distress. When participants were exposed to more COVID news, they experienced more depressed and anxious affect, more COVID distress, less positive affect, and were more likely to use alcohol and cannabis to cope. Further, when participants were exposed to more COVID news, they experienced subsequent increases in depressed affect, decreases in positive affect, and increases in the likelihood of using cannabis to cope. Findings also provided evidence of bi-directional prospective associations between COVID news exposure and COVID distress and of a cumulative impact of COVID news exposure on anxiety, depression, and COVID distress. Findings suggest that individuals should balance the need to remain informed about the pandemic and their own mental health when considering how much COVID news to consume.

Mycoplasmoides genitalium nucleic acid semi-quantitation and molecular macrolide resistance detection via automated assays: gender and specimen source considerations.

A laboratory-developed test (LDT) using analyte-specific reagents has been optimized on a commercial platform to detect macrolide resistance-associated mutations (MRM) in 23S rRNA from Mycoplasmoides genitalium from primary clinical specimens. In this study, MRM-LDT was applied to a multi-specimen source study set. One thousand four hundred ninety-five primary specimens testing positive for M. genitalium by commercial transcription-mediated amplification (TMA) were initially titered by the TMA assay using serial 10-fold dilutions to semi-quantitate target nucleic acid burden. Primary specimens were then processed for MRM detection using the MRM-LDT. Findings were stratified by gender and specimen source. The mean log10 target nucleic acid titer of a TMA-positive specimen was 3.51 (median 3; range 0-10). Male specimens (n = 1145) demonstrated a mean log10 M. genitalium TMA titer of 3.67; that value observed in 350 female specimens was 2.98 (P < 0.0001). The MRM-LDT detection rate (88.7%) from specimens with log10 M. genitalium TMA titers ≥ 4 was increased over specimens with log10 titers ≤ 1 (4.5%; P < 0.0002). In females, MRM-LDT was positive from 51.3% of vaginal swab and 34.7% of urine specimens (P = 0.01). In males, MRM-LDT was positive from 65.0% of rectal swab and 55.7% of urine specimens (P = 0.002). Differences were also observed in log10 M. genitalium TMA titers as a function of specimen source. M. genitalium macrolide resistance rates among multiple specimen sources, as determined by MRM-LDT, are high in the United States and can be consistent with target nucleic acid burden within the primary specimen. Caveats experienced within subgroupings support MRM reflex testing on primary M. genitalium-positive specimens. IMPORTANCE: First-line macrolide treatment failure is of increasing concern with Mycoplasmoides genitalium in multiple settings. Recent sexually-transmitted infection treatment guidelines from the United States Centers for Disease Control and Prevention have predicated therapeutic approaches on the availability of a macrolide resistance/susceptibility result from a primary clinical specimen. In this report, we investigate potential correlation between macrolide resistance mutation detection rates (identified by a molecular amplified laboratory-developed test) and transcription-mediated amplification-based rRNA target semi-quantitation. Data reveal that rRNA semi-quantitation and laboratory-developed test detection rate differences exist as a function of gender and specimen source. These data can guide providers in proper specimen selection not only for the laboratory diagnosis of M. genitalium but also macrolide resistance mutation determination from primary clinical specimens.

Improving Delivery and Use of HIV Pre-Exposure Prophylaxis in the US: A Systematic Review of Implementation Strategies and Adjunctive Interventions.

Implementation of pre-exposure prophylaxis (PrEP) to prevent HIV transmission is suboptimal in the United States. To date, the literature has focused on identifying determinants of PrEP use, with a lesser focus on developing and testing change methods to improve PrEP implementation. Moreover, the change methods available for improving the uptake and sustained use of PrEP have not been systematically categorized. To summarize the state of the literature, we conducted a systematic review of the implementation strategies used to improve PrEP implementation among delivery systems and providers, as well as the adjunctive interventions used to improve the uptake and persistent adherence to PrEP among patients. Between November 2020 and January 2021, we searched Ovid MEDLINE, PsycINFO, and Web of Science for peer reviewed articles. We identified 44 change methods (18 implementation strategies and 26 adjunctive interventions) across a variety of clinical and community-based service settings. We coded implementation strategies and adjunctive interventions in accordance with established taxonomies and reporting guidelines. Most studies focused on improving patient adherence to PrEP and most conducted pilot trials. Just over one-third of included studies demonstrated a positive effect on outcomes. In order to end the human immunodeficiency virus (HIV) epidemic in the U.S., future, large scale HIV prevention research is needed that develops and evaluates implementation strategies and adjunctive interventions for target populations disproportionately affected by HIV.

Suggestions for improving healthcare for transgender and gender diverse people in the United States.

Introduction: Transgender and gender diverse (TGD) individuals face disproportionate barriers to accessing affirming healthcare, ranging from individual practitioners' biases to financial constraints and societal-level cisnormativity. Method: This study identified suggestions for improving healthcare from 420 TGD individuals in the United States. Participants responded to an open-ended question about their suggestions for improving healthcare for TGD people. These responses were then coded using thematic analysis, resulting in 22 specific codes under 6 themes. Results: Results indicated a need for eliminating cisnormativity, taking a holistic approach with clients, adjusting conceptual frameworks for care, eliminating accessibility barriers, promoting affirmative interactions with TGD clients, and providing TGD-affirmative training for providers. Notably, these suggestions spanned from the broader, cultural level regarding general understandings of TGD people and gender to micro-level interactions. Conclusions: This study provides important tools for improving TGD care via a reduction of barriers and an increase in competency and affirmation.

Determinants of Type-Specific Human Papillomavirus Concordance Across Anatomic Sites in Young Men Who Have Sex With Men and Transgender Women, 3 U.S. Cities, 2016-2018.

BACKGROUND: Among men who have sex with men (MSM) and transgender women (TGW), the dynamics of human papillomavirus (HPV) infections at different anatomical sites are not well understood. Information on HPV concordance between anatomic sites can inform the extent of autoinoculation, and susceptibility of different anatomic areas to HPV infection. We described and assessed correlates of HPV concordance across anal, oral, and genital samples. METHODS: We enrolled 1876 MSM and TGW aged 18 to 26 years in 3 US cities. Oral, genital, and anal samples were self-collected for type-specific HPV DNA testing (37 types). Demographics, sexual behaviors, and health history were self-reported. Kappa statistics based on percent positive agreement (kappa+) and generalized estimating equations were used to describe and identify correlates of HPV type-specific concordance between anatomic sample pairs. RESULTS: Any HPV was detected in 69.9%, 48.6%, and 7.4% of anal, genital, and oral samples, respectively. Detection of any HPV (concurrence) was most common in anal-genital pairs (40.9%) and uncommon in oral-genital and oral-anal pairs (3.4% and 6.5% respectively). Type-specific concordance was poor across all sample pairs (kappa+ <0.20). Younger age and older age at first sex were positively associated with type-concordant anal-genital infections. Sexual behaviors were unassociated with concordance. CONCLUSIONS: Poor oral/anogenital concordance suggests the oral mucosa has different susceptibility to HPV infection, differential clearance and/or autoinoculation between oral and anogenital sites is unlikely. There was some observed concurrence and concordance between anal and genital sites, unassociated with sexual behavior, suggesting autoinoculation. Longitudinal studies are necessary to further elucidate mechanisms of multisite infections.

Dyadic Moderators of the Minority Stress-HIV Risk Association in Male Couples.

Minority stressors have been linked to HIV risk behaviors among gay, bisexual, queer, and other men who have sex with men (MSM). Committed partnerships are a key context for new HIV infections and coping with minority stress among MSM, but very little work has tested the minority stress-HIV risk link among male couples, and little is known about how processes within one's relationship may exacerbate or buffer this association. The present study examined links between minority stress (i.e., internalized stigma, microaggressions) and HIV transmission risk behaviors (i.e., condomless anal sex with outside partners, breaks in relationship agreements) among male couples, as well as relationship-based moderators (i.e., social support, dyadic coping) of these associations. An analytic sample of male couples from a large cohort study (analytic N = 410 individuals, 205 dyads) completed self-report measures of minority stress, relationship-based moderators, and HIV transmission risk behaviors which were submitted to moderated actor-partner interdependence models (APIMs). In many cases, coping with stress with one's partner buffered the minority stress-HIV transmission link risk. However, findings also suggested situations in which partners may overburden one another with coping, thus exacerbating HIV-related risk behaviors.

Establishing Evidence Criteria for Implementation Strategies: A Delphi Study for HIV Services.

Background: There are no criteria specifically for evaluating the quality of implementation research and recommend implementation strategies likely to have impact to practitioners. We describe the development and application of the Best Practices Rubric, a set of criteria to evaluate the evidence supporting implementation strategies, in the context of HIV. Methods: We developed the Best Practices Rubric from 2022-2023 in three phases. (1) We purposively selected and recruited by email participants representing a mix of expertise in HIV service delivery, quality improvement, and implementation science. We developed a draft rubric and criteria based on a literature review and key informant interviews. (2) The rubric was then informed and revised through two e-Delphi rounds using a survey delivered online through Qualtrics. The first and second round Delphi surveys consisted of 71 and 52 open and close-ended questions, respectively, asking participants to evaluate, confirm, and make suggestions on different aspects of the rubric. After each survey round, data were analyzed and synthesized as appropriate, and the rubric and criteria were revised. (3) We then applied the rubric to a set of research studies assessing 18 implementation strategies designed to promote the adoption and uptake of pre-exposure prophylaxis, an HIV prevention medication, to assess reliable application of the rubric and criteria. Results: Our initial literature review yielded existing rubrics and criteria for evaluating intervention-level evidence. For a strategy-level rubric, additions emerged from interviews, for example, a need to consider the context and specification of strategies. Revisions were made after both Delphi rounds resulting in the confirmation of five evaluation domains - research design, implementation outcomes, limitations and rigor, strategy specification, and equity - and four evidence levels - best practice, promising practice, more evidence needed, and harmful practices. For most domains, criteria were specified at each evidence level. After an initial pilot round to develop an application process and provide training, we achieved 98% reliability when applying the criteria to 18 implementation strategies. Conclusions: We developed a rubric to evaluate the evidence supporting implementation strategies for HIV services. Although the rubric is specific to HIV, this tool is adaptable for evaluating strategies in other health areas.

"Your Package Could Not Be Delivered": The State of Digital HIV Intervention Implementation in the US.

PURPOSE OF REVIEW: Despite continuous innovations and federal investment to create digital interventions addressing the HIV prevention and care continua, these interventions have not reached people in the U.S. at scale. This article reviews what is known about U.S. implementation of digital HIV interventions and presents a strategy to cross the research-to-practice chasm for these types of interventions. RECENT FINDINGS: We conducted a narrative review of U.S.-based original research on implementation of digital HIV interventions and identified few studies reporting on implementation determinants, strategies, processes, or outcomes, particularly outside the context of effectiveness trials. To supplement the literature, in 2023, we surveyed 47 investigators representing 64 unique interventions about their experiences with implementation after their research trials. Respondents placed high importance on intervention implementation, but major barriers included lack of funding and clear implementation models, technology costs, and difficulty identifying partners equipped to deliver digital interventions. They felt that responsibility for implementation should be shared between intervention developers, deliverers (e.g., clinics), and a government entity. If an implementation center were to exist, most respondents wanted to be available for guidance or technical assistance but largely wanted less involvement. Numerous evidence-based, effective digital interventions exist to address HIV prevention and care. However, they remain "on the shelf" absent a concrete and sustainable model for real-world dissemination and implementation. Based on our findings, we call for the creation of national implementation centers, analogous to those in other health systems, to facilitate digital HIV intervention delivery and accelerate progress toward ending the U.S. epidemic.

Rural-Urban Differences in HIV Sexual Risk Behaviors and HIV Service Utilization Among Adolescent Sexual Minority Males in the United States.

In the United States, HIV prevalence is increasing in rural areas, specifically among rural adolescent sexual minority males (ASMM). However, it is unclear what HIV sexual risk behaviors rural ASMM engage in and what HIV preventative services they utilize. This study aimed to (1) document the lifetime HIV sexual risk behaviors and service utilization of rural ASMM and (2) compare rural-urban differences in the prevalence of HIV sexual risk behaviors and service utilization. We analyzed data collected from 1615 ASMM who participated in a baseline survey for an online HIV prevention program from April 2018 to June 2020. We compared the prevalence of lifetime HIV sexual risk behaviors and HIV healthcare utilization among rural and urban participants via descriptive statistics, chi-square tests, linear and logistic regressions, and zero-inflated Poisson regressions. These analyses indicated that rural ASMM were more likely than urban ASMM to engage in condomless sex when they had anal sex. Rural ASMM could benefit from offline and online evidence-based HIV prevention interventions, especially interventions that increase condom use.

Co-designing strategies to implement long-acting injectable PrEP for sexual minority men in Chicago: a study protocol for an innovation tournament and implementation mapping.

BACKGROUND: Participatory design approaches can improve successful selection and tailoring of implementation strategies by centering the voices of key constituents. To reduce incidence of the human immunodeficiency virus (HIV) in the USA, co-design of implementation strategies is needed for long-acting injectable cabotegravir (CAB-LA), a new form of HIV pre-exposure prophylaxis, among the disproportionately impacted population of sexual minority men (SMM). This manuscript describes the protocol for participatory design approaches (i.e., innovation tournament and implementation mapping) to inform implementation of CAB-LA among SMM (≥ 12 years), particularly Black and Latino populations, in Chicago. METHODS: This research incorporates innovative methods to accomplish two objectives: (1) to crowdsource ideas for the design of implementation strategies for CAB-LA through a virtual innovation tournament and (2) to leverage the ideas from the innovation tournament to operationalize implementation strategies for CAB-LA thorough the systematic process of implementation mapping. A committee of constituents with diverse expertise and perspectives (e.g., SMM, implementation scientists, HIV clinicians, public health leadership, and community partners) will provide input throughout the design process. DISCUSSION: This research will produce a menu of co-designed implementation strategies, which can guide plans for CAB-LA integration in Chicago and provide insights for other EHE regions. Further, as the first innovation tournament focused on HIV prevention, this research can provide a framework for participatory approaches across the care continuum. Given that the co-design of implementation strategies often does not involve the participation of individuals with lived experiences, this work will center the voices of those who will benefit most.

Experiences of Successful PrEP Uptake Among Adolescent Sexual Minority Men in the United States: A Qualitative Exploration.

Male adolescent sexual minorities are at elevated risk of HIV acquisition yet demonstrate low rates of PrEP uptake. Understanding the experiences of adolescents who have successfully accessed PrEP may inform ways to best support adolescents seeking PrEP. Adolescent sexual minorities (N = 100) who reported utilizing PrEP responded to open-ended items asking about their initial PrEP experiences and advice for others. Qualitative analysis suggested that adolescents' ability to access PrEP is influenced by managing parental involvement and seeking culturally competent health care providers. Additionally, they reported how the benefits and drawbacks of taking PrEP played a role in their PrEP use. Findings suggest that educational PrEP interventions targeted at this population could improve uptake by incorporating discussions on side effects and mental health benefits associated with PrEP use. Structural interventions are warranted that improve adolescents' ability to seek sexual health care independently and make room for parental involvement when adolescents could benefit from their support.

Adjunctive interventions: change methods directed at recipients that support uptake and use of health innovations.

BACKGROUND: Implementation science groups change methods into two categories: (1) clinical, behavioral, or biomedical intervention targeting recipient's health outcomes and (2) implementation strategies targeting the delivery system. Differentiating interventions from strategies based on their intended functions is critical to accurately attributing their effects to health or implementation outcomes. However, in coordinating 200+ HIV implementation research projects and conducting systematic reviews, we identified change methods that had characteristics of both interventions and strategies that were inconsistently categorized. To alleviate confusion and improve change method specification, we propose that implementation science should adopt an extant but rarely used term-adjunctive interventions-to classify change methods that are distinct from the common intervention/strategy taxonomy. MAIN TEXT: Adjunctive interventions as change methods that target recipients (e.g., patients, participants) of a health intervention but are designed to increase recipients' motivation, self-efficacy, or capacity for initiating, adhering to, complying with, or engaging with the health intervention over time. In two of our published reviews on implementation of HIV interventions, 25 out of 45 coded change methods fell into this gray area between strategy and intervention. We also noted instances in which the same change method was labelled as the intervention ("the thing"), as an adjunctive intervention, or an implementation strategy in different studies-further muddying the waters. Adjunctive interventions are distinguished from other change methods by their intended targets, desired outcomes, and theory of action and causal processes. Whereas health interventions target recipients and have a direct, causal effect on the health outcome, adjunctive interventions enhance recipients' attitudes and behaviors to engage with the intervention and have an indirect causal link to the health outcome via increasing the probability of recipients' utilization and adherence to the intervention. Adjunctive interventions are incapable of directly producing the health outcome and will themselves require implementation strategies to effectively impact sustained uptake, utilization, and adherence. Case examples, logic modeling, and considerations (e.g., relationship to consumer engagement strategies) for adjunctive intervention research are provided. CONCLUSION: Conceptualizing adjunctive interventions as a separate type of change method will advance implementation research by improving tests of effectiveness, and the specification of mechanisms and outcomes.

Infectious Illness Symptoms Are Associated with Elevated Anxiety in a Sample of Sexual and Gender Minority Young Adults During the COVID-19 Pandemic.

BACKGROUND: To evaluate whether infectious illness symptoms (IIS) are associated with generalized anxiety symptoms during the COVID-19 pandemic in sexual/gender (SGM) minority young adults assigned male at birth (AMAB). METHOD: Four hundred eighteen participants (median age = 25; range, 20-40) were recruited through RADAR, an ongoing Chicago-based cohort study of SGM-AMAB between September 2020 and February 2021. Participants completed online surveys. A subset (n = 145) provided dried blood spot samples to assess SARS-CoV-2 serostatus. RESULTS: One hundred twenty participants (28.7%) had GAD-7 scores of 10 or greater, which indicates generalized anxiety symptoms that may be clinically significant. In a binomial logistic regression model adjusting age, gender identity, race/ethnicity, substance use, and HIV status, the authors found that having a higher IIS count since March 1, 2020, was associated with greater odds of having a GAD-7 score of 10 or greater (OR = 1.14; 95% CI, 1.04, 1.25; P = 0.007). This effect was more pronounced in a binomial logistic regression model adjusting for the same covariates but using current IIS count as the independent variable (OR = 1.39; 95% CI, 1.13, 1.74; P = 0.002). CONCLUSION: Among SGM-AMAB young adults, those who experienced ISS reported higher scores on the GAD-7, a widely used and validated screening measure for generalized anxiety symptoms. These findings highlight the importance of screening for anxiety disorders when patients present with IIS in clinical settings and psychobehavioral health follow-ups when indicated.

Problematic Cannabis Use Is Associated with Reduced Rectal Microbial Species Richness and Diversity Among a Pilot Sample of Young Sexual and Gender Minorities.

Compared to young heterosexual men, young sexual and gender minorities (YSGM) have elevated systemic inflammation and unique intestinal microbial profiles, influenced by HIV infection and substance use. However, links between cannabis use and microbial dysbiosis in this population have not been well described. In this pilot study, we aimed to characterize the complex interrelationships between cannabis use and microbial community structure in YSGM in relationship to HIV status. Cannabis use was assessed by self-administered Cannabis Use Disorder Identification Test (CUDIT) questionnaires and rectal microbial community alpha-diversity metrics were assessed via 16S ribosomal ribonucleic acid (rRNA) sequencing in a subset of YSGM (n = 42) in the RADAR cohort (aged 16-29) in Chicago. Multivariable regression models were used to assess the relationship between cannabis use and microbiome alpha-diversity metrics, adjusting for HIV status and other risk characteristics, including inflammation, which was evaluated by plasma levels of C-reactive protein (CRP). Problematic cannabis use, but not general use, was significantly inversely associated with microbial community richness (Adj. Beta = -8.13; 95% confidence interval [CI]: -15.68 to -0.59) and Shannon diversity (Adj. Beta = -0.04; 95% CI: -0.07 to 0.009). No significant association was observed between CUDIT score and community evenness, nor was any significant moderation observed by HIV status. We observed that problematic cannabis use was associated with reduced microbial community richness and Shannon diversity, adjusting for within population differences in inflammation and HIV status. Future research should aim to assess how cannabis use contributes to microbiome-related health factors among YSGM and if decreasing cannabis use can restore gut microbial community structure.

Social Media and Online Dating Safety Practices by Adolescent Sexual and Gender Diverse Men: Mixed-Methods Findings From the SMART Study.

PURPOSE: Sexual and gender diverse youth (SGDY) develop and employ safety strategies on their own to manage risks while using dating apps. This study aimed to describe the online dating safety practices of SGDY and determine the effectiveness of an eHealth HIV-prevention educational intervention with dating safety content to promote future safety behaviors. METHODS: SGDY aged 13-18 from across the United States (N = 1087) were assigned to increasingly intensive HIV-prevention educational programs using a sequential multiple-assignment randomized trial design. Data were collected at three time points, each three months apart. Participants were asked multiple-choice and open-ended questions about the safety practices they used online and in person; mixed-methods described the safety behaviors of SGDY. Logistic regressions were used to determine psychosocial predictors of safety behaviors and the effectiveness of the intervention in promoting future safety practices. RESULTS: 60% (n = 662) of participants used dating apps, most of whom reported using online (96.4%, n = 638) and in-person (92.9%, n = 615) safety strategies, such as limiting the disclosure of personal information or meeting other users in public. Outness and previous victimization were important psychosocial predictors of engaging in safety behaviors. Additionally, participants who received the online safety education were over 50% more likely to employ certain safety behaviors than SGDY who did not. DISCUSSION: While most SGDY reported at least 1 type of safety strategy when dating online, safety practices differed across psychosocial variables, such as outness. This study provides evidence for the effectiveness of an eHealth educational intervention tailored to SGDY to promote additional safety behaviors.

Syphilis Prevalence, Incidence, and Demographic Differences in a Longitudinal Study of Young Sexual and Gender Minority Adults Assigned Male at Birth.

BACKGROUND: Syphilis rates in the United States have increased. Few studies have examined syphilis incidence and prevalence prospectively among young sexual and gender minorities (YSGM). METHODS: This study of YSGM assigned male at birth comes from a Chicago-based prospective cohort at 2 visits 6 months apart (N = 882). Syphilis cases were identified through serologic test results and self-reported history. RESULTS: In this sample, 25.1% had a lifetime prevalence, and 3.3% were incident cases with a crude incidence rate of 6.76 per 100 person-years. CONCLUSIONS: Lifetime syphilis and incidence are high in this sample of YSGM relative to general population samples.
