Patient and provider medication preferences affect treatment outcomes among adolescents and young adults with opioid use disorder.

BACKGROUND: The opioid epidemic in the United States has not spared youth or young adults, as evidenced by a six-fold increase in opioid use disorder (OUD) diagnoses in the last two decades. Given this dramatic rise, a call for greater uptake and accessibility of medications for opioid use disorder (MOUDs) among youth and young adults has ensued, resulting in an increasing number of MOUD treatment pathways for this vulnerable population. METHODS: This secondary data analysis seeks to characterize patient and provider preferences for MOUD treatment pathways, and test for associations between baseline MOUD treatment preferences and opioid use and treatment adherence outcomes. Participants included 288 youth and young adults (age 15-21 years), recruited from a residential treatment program in Maryland. The study assessed patient preferences at baseline (n = 253) and provider preferences at patient treatment discharge (n = 224). Mixed-effects negative binomial regression models were conducted for opioid use outcomes, and logistic regressions were conducted for treatment adherence outcomes. RESULTS: Results indicate that congruence of treatment with patients' (Incidence Rate Ratio [IRR] = 0.65) and providers' (IRR = 0.66) preferences was significantly associated with reduced self-reported days of opioid use in the past 90 days, but only for patients receiving extended-release naltrexone (XR-NTX). Results also indicated that patients were less likely to switch medication treatment pathways (e.g., from XR-NTX to buprenorphine, or vice versa) during follow-up if they received their preferred treatment at baseline, a finding which held true for both XR-NTX (Odds Ratio [OR] = 0.32) and buprenorphine (OR = 0.22). CONCLUSIONS: Receipt of MOUD congruent with patient and provider preferences was associated with reduced opioid use and greater treatment adherence in this sample of youth and young adults with OUD.

Comparing outcomes of extended-release naltrexone in adolescents and young adults with opioid use disorder.

INTRODUCTION: Opioid use among youth is a public health concern in the United States, with >3300 overdose deaths occurring nationally each year. Unfortunately, youth in the United States are still prescribed medication for opioid use disorder (OUD) at a lower rate than their adult counterparts. METHODS: From 10/2013 to 01/2018, adolescents (ages 15-17; n = 25) and young adults (ages 18-21; n = 263) with moderate to severe OUD enrolled in the parent trial of extended-release naltrexone (XR-NTX; n = 82) versus treatment-as-usual (TAU; either buprenorphine maintenance [n = 94] or counseling without buprenorphine maintenance [n = 112]). The study assessed opioid use outcomes for adolescents vs. young adults using timeline follow-back self-report procedures at baseline and 3-/6-month follow-up assessments. Mixed-effects longitudinal and clustered panel regression models compared treatment effects over time of XR-NTX and TAU on opioid use outcomes in this secondary analysis. RESULTS: Though adolescent participants reported significantly less opioid use at baseline relative to their young adult counterparts (p < 0.05), the two age groups reported similar rates of opioid use throughout the intervention period. Additionally, both adolescents and young adults receiving XR-NTX evidenced lower rates of opioid use than those receiving TAU at all time points, and adolescents on XR-NTX were the only group who reduced their opioid use at all time points. Mixed-effects models indicated adolescents receiving XR-NTX demonstrated a 48 % lower rate of opioid use days [Incidence Rate Ratio (IRR) = 0.52; p = 0.020], while young adults receiving XR-NTX reported an estimated 26 % lower rate (IRR = 0.74; p = 0.009). CONCLUSIONS: Results indicate that adolescents respond favorably to XR-NTX relative to TAU for treatment of OUD, demonstrating similar outcomes to young adults.

Virtual avatars as a new tool for human immunodeficiency virus prevention among men who have sex with men: a narrative review.

Background and Objective: Human immunodeficiency virus (HIV) continues to affect sexual and gender minorities, predominantly men who have sex with men (MSM). Stigma, medical mistrust, and apprehension towards discussing sexual health with one's medical provider are significant barriers in seeking or accessing preventive services. Those obstacles could be surpassed through novel digital and electronic health interventions, specifically with virtual avatar technology. Avatars are digital self-representative agents that are controlled with an interactive electronic device. Avatars allow for virtual self-immersion within infinitely customizable environments to practice skill building, fostering relationships and more, through an optional incognito approach. The objective of this narrative review is to examine recent uses of and developments in avatar technology, highlight the personalization attribute of this technology, and evaluate its strengths and limitations as a tool for HIV prevention among MSM. Methods: We reviewed recent scientific literature generated by PubMed that use virtual avatar technology in HIV prevention and treatment among populations put at risk. Articles that met the inclusion criteria were then categorized on how the avatar technology was used. Key Content and Findings: We identified eleven studies that met inclusion criteria. Avatar technology was found to create a comfortable environment for participants to address and discuss their sexual behaviors with less hesitation. Avatars can build rapport with populations put at high risk, creating an opportunity for reevaluation of their sexual behavior while assisting them in being able seek information, preventive services, or treatment for HIV or other sexually transmitted infections (STIs). Conclusions: Given the increased use of digital technology in health and prevention, avatars might be useful in sexual health education and HIV prevention among populations put at risk. The benefits and potential in utilizing this technology for HIV prevention are highlighted.

Peer Case Management Promoting Advancement Along the HIV Care Continuum Among Black Men Who Have Sex with Men Living with HIV: Building Brothers Up.

Black men who have sex with men (BMSM) in the United States are at elevated risk for HIV relative to their heterosexual and/or non-BMSM counterparts, yet on average demonstrate suboptimal HIV care linkage and rates of HIV primary care retention. From October 2019 to December 2020, 69 adult (i.e., aged 18-65) BMSM enrolled in Building Brothers Up (2BU), a 6-session peer case management intervention delivered across 3 months and designed to improve retention in HIV primary care through to full viral suppression. Peer case management sessions included detailed assessment of participants' needs and barriers to treatment, which led to the development of a participant-centered treatment plan. All participants self-identified as Black, about three-quarters self-identified as gay (72.5%), and 46.4% reported an annual income of $5000 or less. A total of 69 participants enrolled in 2BU; however, multiply imputed chained equation logistic regressions were carried out on the final analytical data set (n = 40; 99 imputations) due to a large amount of COVID-19-related missing data. Although analyses of retention and achievement of viral suppression did not reach full significance, the probability of a Type-II hypothesis testing error was high, and viral load results (adjusted odds ratio = 1.56; 95% confidence interval = 0.94-2.60; p = 0.08) suggested that increased attendance to peer case management sessions may be associated with improved odds of achieving full viral suppression among BMSM. The significant impact of national race-related civil unrest and the COVID-19 pandemic on the target population during implementation of 2BU is underscored.

Associations Between Gender Identity Control, Gender Identity Non-Verification, and Health Risks among Trans Women of Color Living with HIV.

This study applied Identity Theory (IT) metrics to data gathered from a sample of trans women of color living with HIV to determine whether measures of identity control and/or identity non-verification were associated with trans women's self-reported health risks. From February 2014 through August 2016, 139 HIV-positive trans women were enrolled. Cross-sectional time-series regressions indicated that identity control and identity non-verification were both associated with self-reported behavioral and health outcomes. Increased gender identity control was associated with decreased drug and alcohol use (multiple Logit [L]; all p < .05) and decreased likelihood of self-reported infection with a sexually transmitted infection (STI; multiple L; all p < .05); increased perceived identity non-verification was associated with increased severity of depression symptoms (b = 0.09) as well as increased odds of engagement in exchange sex (L = 0.32), increased drug and alcohol use (multiple L p > .05), and increased likelihood of self-reported infection with viral STIs (Lgenital warts = 0.49; Lherpes = 0.69). These findings indicate IT may be a useful theoretical framework through which to understand and analyze behavior among trans women of color living with HIV. Identity verification dynamics in particular may be useful mechanisms to explain engagement in several potentially harmful behaviors.

Optimizing outpatient treatment outcomes among methamphetamine-using gay and bisexual men through a computerized depression intervention.

INTRODUCTION: Depression is a common sequelae of frequent methamphetamine use, and may influence rates of engagement in sexual risk-taking among methamphetamine-using cisgender gay, bisexual, and other men who have sex with men (GBMSM). The study team hypothesized that layering a brief, computerized depression intervention (i.e., MoodGym; based on Cognitive Behavioral Therapy [CBT] and Interpersonal Therapy) on top of a long-running outpatient methamphetamine treatment program (based on CBT and Contingency Management) for GBMSM could optimize reductions in methamphetamine use and sexual risk-taking among program participants. METHODS: This pilot study, which also included analysis of historical data, employed nearest-neighbor matching algorithms to match current pilot study participants (N = 39) to prior participants of an outpatient methamphetamine treatment program (N = 703) and employed treatment effects analyses to determine the observed effects of adding depression intervention content to GBMSM-specific methamphetamine treatment. RESULTS: Pilot study participants who received the MoodGym intervention were significantly less likely to submit methamphetamine-metabolite positive urine samples (Adjusted Treatment Effect [ATE] = -0.72; p < 0.01), and evidenced significantly greater reductions in receptive condomless anal intercourse with non-primary partners in the past 30 days (ATE = -1.39; p < 0.05), relative to prior participants of the outpatient methamphetamine treatment program who did not receive depression intervention content. CONCLUSION: Preliminary results suggest layering a brief computerized depression intervention onto outpatient methamphetamine treatment for GBMSM may optimize reductions in methamphetamine use and/or sexual risk-taking.

Age Is Associated With HIV Sexual Risk Behaviors Among Trans Women in Los Angeles County.

Little is known about how HIV risk varies among trans women of different ages. From January 2010 to February 2021, 2,242 trans women were assessed via outreach encounters consisting of health education and risk reduction information, and queries of recent sexual behaviors. Generalized linear models provide adjusted rates of engagement in condomless anal intercourse (CAI), in exchange sex, and CAI with exchange partners in the past 30 days for each year from age 18 to 60. Most participants identified as Hispanic/Latina (52%) and most were HIV negative (80%). Engagement in exchange sex remained prevalent from participants' early 20s through their mid-40s, though CAI with such partners never exceeded an average estimated prevalence of 15%. Condomless behaviors with non-exchange partners was more common, with at least 20% reporting engagement in non-exchange CAI regardless of age. The need for trans-specific sexual risk reduction interventions that take age into account is underscored.

Depression and HIV Transmission Risk among Methamphetamine-Using Men who have Sex with Men.

BACKGROUND: Methamphetamine use is associated with disproportionate risk of HIV infection and increased risk of depression among sexual minority men. The purpose of the study was to estimate the association between clinical depression diagnoses and sexual risk-taking among cisgender men who have sex with men (MSM) who use methamphetamine. METHOD: From March 2014 through January 2016, 286 MSM who use methamphetamine but were not seeking treatment for methamphetamine use disorder were enrolled to participate in a technology-based randomized controlled trial to reduce methamphetamine use and HIV sexual risk behaviors; participants were assessed for major depressive episodes (MDE) and persistent depressive disorder (PDD) at baseline. Multivariate clustered zero-inflated negative binomial regression analyses of condomless anal intercourse (n=282; 1,248 visits) estimated the association between this baseline diagnostic result and engagement in sexual risk-taking over time. RESULTS: Participants predominantly identified as non-white (80%), averaged 42 years of age, and reported a HIV prevalence rate of 46%. Engagement in sexual risk-taking consistently demonstrated a positive curvilinear relationship with clinical depression severity, such that, for example, participants without clinical depression (59% of the sample; coef.=1.16) and those with MDE (36% of the sample; coef.=1.45) both demonstrated elevated rates of condomless anal sex with anonymous partners relative to participants with PDD (5% of the sample; analytical reference category; both coef. p<0.05). Data also demonstrated a trend (p = 0.053) of reduced sexual risk-taking with main partners among participants diagnosed with MDE (coef.=-0.94). CONCLUSIONS: Methamphetamine use among participants in this study inverted the functional form of the relationship between depression and sexual risk among MSM observed in prior studies. Whereas low-grade depression has been associated with increased sexual risk-taking in prior samples of MSM, methamphetamine upends this relationship, such that the greatest engagement in sexual risk-taking occurred among those diagnosed with MDE at baseline. Additional research is warranted to clarify how methamphetamine influences sexual risk-taking among MSM with/without comorbid depression.

Text Messaging Improves HIV Care Continuum Outcomes Among Young Adult Trans Women Living with HIV: Text Me, Girl!

Young adult trans women living with HIV in the US exhibit suboptimal advancement through the HIV Care Continuum relative to national averages. From December 2016 through May 2018, 134 young adult trans women living with HIV enrolled in Text Me, Girl!, a theory-based, trans-specific text-messaging intervention designed to improve HIV Care Continuum outcomes. Participants (N = 130) averaged 29.5 years, were predominantly Latinx (43%) or African American/Black (40%). Clustered logistic and ordinal logistic multivariable models (n = 105; 366 observations) indicate that through 18-month follow-up, increased exposure to the text-messaging intervention was associated with significant (p < 0.05) increased retention to HIV care (adjusted odds ratio [aOR] 1.33) and biomarker-confirmed viral suppression (aOR 1.51); retention in the intervention was associated with significantly increased likelihood of ART uptake (aOR 2.95) and "excellent" ART adherence (aOR 10.44). Text Me, Girl! offers promising evidence that a unidirectional, automated text-messaging intervention can improve HIV care outcomes among young adult trans women living with HIV.

Social Networks and Exchange Sex among Transgender Women.

Transgender women are more likely to exchange sex than cisgender individuals. This study investigated how social networks were associated with exchange sex among transgender women in Los Angeles County. From July 2015 to September 2016, transgender women (N = 271; "egos") reported their sexual and substance use behaviors and perceptions of the same behaviors among their peers (N = 2,619; "alters"). Clustered logistic and negative binomial regressions were used to model odds of exchange sex and number of exchange sex partners in the past 6 months, respectively. Transgender women who perceived that any of their peers were engaged in exchange sex were approximately four times more likely to exchange sex themselves and reported three times as many exchange sex partners as those who did not perceive any peers engaged in exchange sex. Perceived ecstasy use among peers was associated with higher odds of exchange sex and more exchange sex partners, whereas perceived marijuana use among peers was associated with lower odds of exchange sex and fewer exchange sex partners. Peer behaviors were strongly associated with both transgender women's likelihood and rate of engagement in exchange sex. Risk reduction interventions with transgender women should attend to network dynamics that are often overlooked in existing programs.

A Theory-Based mHealth Intervention (Getting Off) for Methamphetamine-Using Men Who Have Sex With Men: Protocol for a Randomized Controlled Trial.

BACKGROUND: Methamphetamine (meth) use among men who have sex with men (MSM) is associated with increased HIV prevalence and transmission and substandard advancement along the HIV prevention and care continuum. Given the growth of mobile health (mHealth) technologies, it is no longer necessary to limit meth treatment options to physical, brick-and-mortar sites, and administration using generic, nontailored content. OBJECTIVE: In a 2-arm randomized controlled trial (RCT; N=300), we aim to evaluate the use of an mHealth intervention (Getting Off) to assess the impact and noninferiority of a cross-platform app (developed from a manualized meth treatment intervention) to help MSM reduce meth use and HIV sexual risk behaviors and improve their advancement along the HIV prevention and care continuum (HIV testing, pre-exposure prophylaxis uptake and persistence, and antiretroviral therapy uptake and adherence). METHODS: Participants will be randomized into 2 arms: arm A, with immediate access to the app (immediate delivery: n=150), or arm B, with delayed access to the app after a 30-day period (delayed delivery: n=150). Participants in both arms will use the same Getting Off app and will have 30 days to complete the 24 sessions. Participants will be assessed at the 1-, 2- (delayed delivery arm only), 3-, 6-, and 9-month timepoints to determine observed treatment effects and will be compared with a historical matched sample of participants (n=~600) who received the brick-and-mortar group-based Getting Off intervention. RESULTS: Recruitment began in January 2019 for phase 1, the formative phase. In January and February 2019, 4 focus groups (N=36) were formed to provide input on the adaptation of the group-based manual intervention to a mobile app. Data collection for phase 2, the RCT, is expected to be completed in January 2023. The final results are anticipated in April 2023. CONCLUSIONS: By creating a culturally responsive mobile app, Getting Off aims to reduce meth use and improve sexual health outcomes among meth-using MSM. The Getting Off app could have significant public health impact by greatly expanding access to effective, affordable, private, culturally competent, and highly scalable meth treatment for MSM.

Network Characteristics Associated with HIV Testing Conversations Among Transgender Women in Los Angeles County, California.

This study examined associations between transgender women's social network characteristics, perceived network member HIV risk/protective behaviors and HIV testing conversations between transgender women and their network members. From July 2015 to September 2016, 264 transgender women who nominated 2529 social network members completed surveys on sociodemographic characteristics, HIV risk/protective behaviors, and egocentric social networks. Mixed-effects logistic regression evaluated discussion of HIV testing with network member characteristics and perceived HIV risk/protective behaviors. HIV testing conversations were positively associated with being named as a trans "mother" (aOR 2.05; 95% CI 1.03-4.06) relationships of longer duration, and the following network member characteristics: perception as a confidant (3.09; 1.89-5.05), discussion of condom use (29.65; 16.75-52.49), knowledge of HIV pre-exposure prophylaxis (4.14; 2.11-8.15), and receipt of HIV testing (22.13; 11.47-42.69). HIV testing conversations were negatively associated with relationships where stimulants were used (aOR 0.32; 95% CI 0.12-0.84). These results indicate the importance of leveraging close relationship networks to increase HIV testing and the potential role for network-based HIV prevention strategies among transgender women.

A Novel Adaptation of Peer Health Navigation and Contingency Management for Advancement Along the HIV Care Continuum Among Transgender Women of Color.

Transgender women, particularly racial/ethnic minority transgender women, evidence disproportionately high rates of untreated HIV infection and disproportionately low rates of HIV viral suppression. The Alexis Project was a combined peer health navigation (PHN) and contingency management (CM) intervention that targeted HIV milestones associated with advancement along the HIV care continuum. From February 2014 through August 2016, 139 transgender women of color (TWOC) enrolled and received unlimited PHN sessions and an escalating CM rewards schedule for confirmed achievement of both behavioral (e.g., HIV care visits) and biomedical (e.g., viral load reductions and achieved/sustained viral suppression) HIV milestones. Results demonstrated that increased attendance to PHN sessions was associated with significant achievement of both behavioral (coef. range 0.12-0.38) and biomedical (coef. = 0.10) HIV milestones (all p ≤ 0.01); 85% were linked to HIV care, and 83% who enrolled detectable and achieved the minimum 1 log viral load reduction advanced to full viral suppression. The combined PHN and CM intervention successfully promoted advancement along the HIV Care Continuum, with particularly robust effects for behavioral HIV milestones.

Drug Use is Associated with Delayed Advancement Along the HIV Care Continuum Among Transgender Women of Color.

Transgender women are impacted by elevated rates of HIV infection and drug use. This study investigated effects of drug use on HIV care outcomes among transgender women of color living with HIV who enrolled in a combined peer health navigation (PHN) and contingency management intervention (N = 129). At baseline, 71.3% reported any drug use in the past 6 months. Linkage to HIV care was delayed for users of any stimulant compared to non-users of stimulants, and for methamphetamine users compared to non-users of methamphetamine. Any drug use, relative to no drug use, was associated with fewer HIV care visits (IRR 0.50, 95% CI [0.30, 0.85]), but did not significantly impact ART adherence, or attaining an undetectable viral load. PHN sessions were positively related to the number of HIV care visits (IRR 1.20, 95% CI [1.07, 1.34]), especially for users of any stimulant and for methamphetamine users, to ART adherence (OR 2.54, 95% CI [1.67, 3.86]), and to virological suppression (OR 7.57, 95% CI [1.64, 34.94]). These findings demonstrate the value of assessing drug use as a possible barrier to HIV care.

Predictors of Internet Health Information-Seeking Behaviors Among Young Adults Living With HIV Across the United States: Longitudinal Observational Study.

BACKGROUND: Consistent with young adults' penchant for digital communication, young adults living with HIV use digital communication media to seek out health information. Understanding the types of health information sought online and the characteristics of these information-seeking young adults is vital when designing digital health interventions for them. OBJECTIVE: This study aims to describe characteristics of young adults living with HIV who seek health information through the internet. Results will be relevant to digital health interventions and patient education. METHODS: Young adults with HIV (aged 18-34 years) self-reported internet use during an evaluation of digital HIV care interventions across 10 demonstration projects in the United States (N=716). Lasso (least absolute shrinkage and selection operator) models were used to select characteristics that predicted whether participants reported seeking general health and sexual and reproductive health (SRH) information on the internet during the past 6 months. RESULTS: Almost a third (211/716, 29.5%) and a fifth (155/716, 21.6%) of participants reported searching for general health and SRH information, respectively; 26.7% (36/135) of transgender young adults with HIV searched for gender-affirming care topics. Areas under the curve (>0.70) indicated success in building models to predict internet health information seeking. Consistent with prior studies, higher education and income predicted health information seeking. Higher self-reported antiretroviral therapy adherence, substance use, and not reporting transgender gender identity also predicted health information seeking. Reporting a sexual orientation other than gay, lesbian, bisexual, or straight predicted SRH information seeking. CONCLUSIONS: Young adults living with HIV commonly seek both general health and SRH information online, particularly those exploring their sexual identity. Providers should discuss the most commonly sought SRH topics and the use of digital technology and be open to discussing information found online to better assist young adults with HIV in finding accurate information. Characteristics associated with health information-seeking behavior may also be used to develop and tailor digital health interventions for these young adults.

Associations Between Social Support and Social Media Use Among Young Adult Cisgender MSM and Transgender Women Living With HIV.

Social media platforms offer the opportunity to develop online social networks. Use of these platforms has been particularly attractive to younger sexual and gender minority individuals as well as those living with HIV. This cross-sectional study examined the perceived level of social support and associations with social media use among youth and young adult cisgender men who have sex with men (MSM) and transgender (trans) women living with HIV and examined these associations by gender identity. The study drew from baseline data collected from 612 cisgender MSM and 162 trans women enrolling in one of 10 demonstration sites that were part of a Health Resources and Services Administration Special Projects of National Significance initiative. The individual projects were designed to evaluate the potential for social media/mobile technology-based interventions to improve retention in care and HIV health outcomes. The data used in this study came from baseline surveys completed when participants enrolled in a site between October 2016 and May 2018. Results demonstrated that a significantly greater proportion of MSM than trans women participants reported the use of social media platforms (e.g., Facebook: MSM = 86%, trans women = 62%; Instagram: MSM = 65%, trans women = 35%). Furthermore, increased social media use improved perceptions of social support only among MSM participants (direct adjusted OR = 1.49) and not trans women participants (gender identity interaction term adjusted OR = 0.64). These results revealed that MSM participants perceived greater social benefit from the use of social media platforms than trans women, which could be a result of generalized online transphobia experienced by trans women. More nuanced data on various social media platforms, that is, anonymous versus profile-based, and group differences, are needed to better understand how social media platforms can be best utilized to optimize health care outcomes among sexual and gender minority youth and young adults living with HIV.

Text Messaging to Improve Linkage, Retention, and Health Outcomes Among HIV-Positive Young Transgender Women: Protocol for a Randomized Controlled Trial (Text Me, Girl!).

BACKGROUND: Transgender women in the United States experience numerous risk factors for HIV acquisition and transmission, including increased rates of homelessness, alcohol and drug use, sex work, and nonprescribed hormone and soft tissue-filler injections. In addition, transgender women face discrimination and social/economic marginalization more intense and deleterious than that experienced by lesbian, gay, or bisexual individuals, further worsening health outcomes. Although little research has been done specifically with young transgender women aged 35 years and younger, existing evidence suggests even further elevated rates of homelessness, substance use, and engagement in HIV transmission risk behaviors relative to their older transgender women and nontransgender young adult counterparts. Young transgender women living with HIV experience a range of barriers that challenge their ability to be successfully linked and retained in HIV care. OBJECTIVE: The aim of this randomized controlled trial, Text Me, Girl!, is to assess the impact of a 90-day, theory-based, transgender-specific, text-messaging intervention designed to improve HIV-related health outcomes along the HIV care continuum among young (aged 18-34 years) transgender women (N=130) living with HIV/AIDS. METHODS: Participants were randomized into either Group A (immediate text message intervention delivery; n=61) or Group B (delayed text message intervention delivery whereby participants were delivered the text-messaging intervention after a 90-day delay period; n=69). Over the course of the 90-day intervention, participants received 270 theory-based text messages that were targeted, tailored, and personalized specifically for young transgender women living with HIV. Participants received 3 messages per day in real time within a 10-hour gradual and automated delivery system. The text-message content was scripted along the HIV care continuum and based on social support theory, social cognitive theory, and health belief model. The desired outcome of Text Me, Girl! was virological suppression. RESULTS: Recruitment began on November 18, 2016, and the first participant was enrolled on December 16, 2016; enrollment closed on May 31, 2018. Intervention delivery ended on November 30, 2018, and follow-up evaluations will conclude on August 31, 2019. Primary outcome analyses will begin immediately following the conclusion of the follow-up evaluations. CONCLUSIONS: Text messaging is a communication platform well suited for engaging young transgender women in HIV care because it is easily accessible and widely used, as well as private, portable, and inexpensive. Text Me, Girl! aimed to improve HIV care continuum outcomes among young transgender women by providing culturally responsive text messages to promote linkage, retention, and adherence, with the ultimate goal of achieving viral suppression. The Text Me, Girl! text message library is readily scalable and can be adapted for other hard-to-reach populations. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/12837.

Associations between sociodemographic characteristics and substance use disorder severity among methamphetamine-using men who have sex with men.

Background: Men who have sex with men (MSM) have elevated rates of substance use disorders (SUDs) and differences across sociodemographic sub-groups of MSM are associated with a greater risk of deleterious outcomes. Although studies have shown that MSM report greater rates of polysubstance use relative to other adult populations, the associations between sociodemographic characteristics and both acute substance use and substance use severity among methamphetamine-using MSM are unknown. Objectives: The present study examines associations between sociodemographic characteristics and (a) recent substance use and (b) SUD severity. Method: From March 2014 to January 2016, 286 methamphetamine-using MSM were recruited to complete a baseline Audio Computer-Assisted Self-Interview (ACASI) assessment and the SCID MINI. Multivariable analyses employed generalized structural equation modeling given the non-continuous nature of the endogenous variables. Results: All measured sociodemographic characteristics except gay self-identification were significantly associated with recent substance use (all ps ≤ .05), and all characteristics except current homelessness were significantly associated with diagnostic SUD severity (all ps ≤ .05). However, nuanced risks were observed in participants' use of specific substances regarding recent substance use and substance use severity. Conclusion: These results suggest that multiple factors contribute to the risks of SUD severity among methamphetamine-using MSM. As such, these results are useful in the tailoring of clinical and psychosocial intervention strategies that serve this and other high-risk populations.

Cost effectiveness of text messages to reduce methamphetamine use and HIV sexual risk behaviors among men who have sex with men.

Methamphetamine use is highly prevalent among gay, bisexual, and other men who have sex with men (MSM) in the United States and has been associated with condomless anal intercourse (CAI), a common route of HIV infection. Text messaging is a very low-cost method of delivery for intervention content. This paper presents a cost-effectiveness analysis of a randomized controlled trial testing three nested methods of text message delivery designed to reduce methamphetamine use and HIV sexual risk behaviors among MSM (Project Tech Support2). From March 2014 to January 2016, 286 non-treatment seeking methamphetamine-using MSM were randomized into one of three study arms: 1) Interactive text message conversations with Peer Health Educators, plus five daily automated, unidirectional theory-based messages, plus a weekly self-monitoring text message assessment (TXT-PHE; n = 94); or, 2) Five daily automated, unidirectional theory-based messages plus a weekly self-monitoring text message assessment (TXT-Auto; n = 99); or, 3) The weekly self-monitoring text message assessment only (AO; n = 93). Methamphetamine use at nine months post-enrollment was lower than at baseline in all three arms. The addition of Peer Health Educators and/or theory-based text messages did not produce cost-effective reductions in methamphetamine use over the weekly AO text messages. However, both intervention arms outperformed the AO arm in reducing HIV risk behaviors, but the TXT-Auto arm dominated the TXT-PHE arm in achieving greater reductions in days of methamphetamine use and CAI at lower cost. The TXT-Auto arm achieved greater reductions in CAI than the attentional control at a cost in the base case of ~$37.50 per episode of CAI reduced per month. Sensitivity analyses showed that results were robust to a number of changes in assumptions. Interventions seeking to reduce methamphetamine use among non-treatment-seeking MSM may seek to add minimal attentional control-style text messages to their routines querying about recent methamphetamine use and/or high-risk sex. Interventions seeking to additionally reduce HIV sexual risk behaviors among non-treatment-seeking MSM, specifically engagement in CAI, may seek to additionally apply theory-based text messages.

A Multilevel Analysis of Social Network Characteristics and Technology Use on HIV Risk and Protective Behaviors Among Transgender Women.

This study examined the empirical structure (i.e., size, density, duration) of transgender women's social networks and estimated how network alters' perceived HIV risk/protective behaviors influenced transgender women's own HIV risk/protective behaviors. From July 2015 to September 2016, 271 transgender women completed surveys on sociodemographic characteristics, HIV risk/protective behaviors, and social networks. Hierarchical generalized linear models examined the associations of social network alter member data 'nested' within participant data. Analyses revealed that social network factors were associated with HIV risk/protective behaviors, and that the gender identity of the alters (cisgender vs. transgender), and social network sites and technology use patterns ("SNS/tech") moderated these associations. Among network alters with whom the participant communicated via SNS/tech, participants' HIV risk behavior was positively associated with alters' HIV risk behavior (cisgender alters aOR 4.10; transgender alters aOR 5.87). Among cisgender alters (but not transgender alters) with whom the participant communicated via SNS/tech, participants' HIV protective behavior was positively associated with alters' HIV protective behavior (aOR 8.94).
