A Network Science Approach to Sex-Polydrug Use Among Black Sexually Minoritized Men and Transgender Women: The N2 Cohort Study.

Black sexually minoritized men (SMM) and transgender women (TW) are subgroups with lower rates of substance use and comparable rates of condom use relative to White SMM and TW yet experience heightened vulnerability to HIV. This study sought to explore associations of substance use, including sex-drug use (i.e., drug or alcohol use during sex to enhance sex), and condomless sex among Black SMM and TW. Data were collected from Black SMM and TW living in Chicago, Illinois, enrolled in the Neighborhoods and Networks (N2) cohort study, from November 2018 to April 2019. We used bivariate analyses followed by a multilevel egocentric network analysis to identify factors associated with condomless sex. We conducted Spearman correlation coefficients to examine correlations between pairs of sex-drugs to enhance sex. We used a bipartite network analysis to identify correlates of sex-drug use and condomless sex. A total of 352 Black SMM and TW (egos) provided information about 933 sexual partners (alters). Of respondents, 45% reported condomless sex and 61% reported sex-drug use. In unadjusted analyses, marijuana (34%) and cocaine/crack (5%) sex-drug use were associated with condomless sex (p < 0.05). Condomless sex was positively associated with sex-polydrug use, or the use of 2+ drugs or 1 drug and alcohol (OR = 1.48; 95% CI: 1.02-2.14; p = 0.039), and negatively associated with sharing an HIV-negative serostatus with a sexual partner (OR = 0.57; 95% CI: 0.33-0.98; p = 0.041), having a different HIV serostatus with a sexual partner (OR = 0.37; 95% CI: 0.21-0.64; p < 0.001) or not knowing the HIV serostatus of a sexual partner (OR = 0.47; 95% CI: 0.26-0.84; p = 0.011). The following pairs of sex-polydrug use had Spearman correlation coefficients higher than 0.3: marijuana and alcohol, ecstasy and alcohol, cocaine/crack and ecstasy, and methamphetamine and poppers (p < 0.05). HIV prevention interventions for Black SMM and TW designed to reduce HIV transmission through egocentric sexual networks could address sex-drug use through sex-positive and pleasure-centered harm reduction strategies and provide and promote biomedical prevention and care options at supraoptimal levels.

Latent Profile Patterns of Network-Level Norms and Associations with Individual-Level Sexual Behaviors: The N2 Cohort Study in Chicago.

Individual-level behavior can be influenced by injunctive and descriptive social network norms surrounding that behavior. There is a need to understand how the influence of social norms within an individual's social networks may influence individual-level sexual behavior. We aimed to typologize the network-level norms of sexual behaviors within the social networks of Black sexual and gender minoritized groups (SGM) assigned male at birth. Survey data were collected in Chicago, Illinois, USA, between 2018 and 2019 from Black SGM. A total of 371 participants provided individual-level information about sociodemographic characteristics and HIV vulnerability from sex (i.e., condomless sex, group sex, use of alcohol/drugs to enhance sex) and completed an egocentric network inventory assessing perceptions of their social network members' (alters') injunctive and descriptive norms surrounding sexual behaviors with increased HIV vulnerability. We used Latent Profile Analysis (LPA) to identify network-level norms based on the proportion of alters' approval of the participant engaging in condomless sex, group sex, and use of drugs to enhance sex (i.e., injunctive norms) and alters' engagement in these behaviors (i.e., descriptive norms). We then used binomial regression analyses to examine associations between network-level norm profiles and individual-level HIV vulnerability from sex. The results of our LPA indicated that our sample experienced five distinct latent profiles of network-level norms: (1) low HIV vulnerability network norm, (2) moderately high HIV vulnerability network norm, (3) high HIV vulnerability network norm, (4) condomless sex dominant network norm, and (5) approval of drug use during sex dominant network norm. Condomless anal sex, group sex, and using drugs to enhance sex were positively and significantly associated with higher HIV vulnerability social network norm profiles, relative to low HIV vulnerability norm profiles. To mitigate Black SGM's HIV vulnerability, future HIV risk reduction strategies can consider using network-level intervention approaches such as opinion leaders, segmentation, induction, or alteration, through an intersectionality framework.

Sleep characteristics among black cisgender sexual minority men and black transgender women during the COVID-19 pandemic: The role of multi-level COVID-19-related stressors.

OBJECTIVES: To determine the association between individual, network, and structural COVID-19-related stressors and changes in sleep duration and quality among Black cisgender sexual minority men (SMM) and Black transgender women during the COVID-19 peak infectivity rate in Chicago. METHODS: From April 20, 2020 to July 31, 2020, we conducted the N2 COVID Study in Chicago (n = 226). The survey included questions regarding multi-level COVID-19-related stressors (eg, food unavailability, partner violence, housing instability, concern about neighborhood COVID-19), sleep duration, and sleep quality. RESULTS: About 19.5% of our sample reported a shorter duration of sleep during the initial peak COVID-19 infectivity, while 41.2% reported more sleep and 38.9% reported about the same. Compared to the prepandemic period, 16.8% reported that their sleep quality worsened in the COVID-19 pandemic, while 27.9% reported their sleep quality had improved and 55.3% reported it was about the same. In multivariable models, we found that ≥1 day of physical stress reaction, worrying about being infected with COVID-19, traveling during COVID-19 being a financial burden, not having enough medication, knowing someone who was diagnosed with COVID-19, partner violence and housing instability were associated with poor sleep health in the COVID-19 pandemic (adjusted risk ratio: 1.82-3.90, p < .05). CONCLUSIONS: These data suggest that COVID-19-related stressors impacted poor sleep duration and quality during the pandemic among this cohort. Multi-level interventions to reduce COVID-19-related stressors (eg, meditation, intimate partner violence prevention and housing programs) may be useful for improving sleep health among Black cisgender sexual minority men and Black transgender women.

Sleep Disturbance is Associated with Missing PrEP Doses Among Young Black Sexual Minority Men in The N2 study.

PrEP uptake and adherence among young Black sexual minority men (YBSMM), has been sub-optimal. Multiple studies identified sleep as an important determinant of medication adherence, although it has not been examined with regard to PrEP among YBSMM. This study utilized data collected from HIV-negative cisgender YBSMM in the Neighborhoods and Networks (N2) study in Chicago using PrEP (N = 70). Sleep quality was measured using the PHQ-9 and PrEP adherence questions were adapted from Reynolds et al., 2004. Bivariate and multivariable regression analyses were used to estimate associations between sleep and missing PrEP doses, controlling for relevant demographic and behavioral factors. YBSMM who reported sleep disturbance a moderate amount of time (aOR 7.59 [1.05 to 54.57]) were more likely to miss taking PrEP because they had too many pills to take. Sleep quality is an overlooked determinant of medication adherence, and may negatively impact YBSMM's ability to consistently take PrEP.

COVID-19 stressors and symptoms of depression and anxiety among Black cisgender sexual minority men and Black transgender women during the initial peak of the COVID-19 pandemic.

PURPOSE: To examine associations between COVID-19-related stressors and symptoms of depression and anxiety in Black cisgender sexual minority men (SMM) and transgender women during the initial peak of the COVID-19 pandemic. METHODS: Participants from the N2 Cohort Study comprised Black cisgender SMM and Black transgender women in Chicago, IL, completed a face-to-face video or phone interview between April 20 and July 31, 2020. The survey included 18 measures of individual, network, and structural COVID-19 stressors such as income loss, network COVID-19 diagnoses, and housing loss, as well as 5 outcome measures: anxiety, depression, loneliness, worry and hope. RESULTS: Of 226 participants, 56.6% experienced anxiety on at least 1 of the last 14 days, 48.7% experienced depression, 48.7% experienced loneliness, 42.0% experienced worry, and 51.8% did not experience hope. Completing the study during a later phase of reopening was associated with hopefulness, RR = 1.37 95% CI [1.02, 1.85]. Fifteen of the 18 multi-level COVID-19 stressors were associated with 1 or more symptoms of depression and anxiety, for example, physical stress reactions, income loss, food loss, medication loss, network COVID-19 diagnoses, partner violence, housing loss, and neighborhood pandemic concerns (aRRs = 0.61-2.78, ps < 0.05). CONCLUSION: COVID-19-related stressors were associated with depression and anxiety symptoms in Black cisgender SMM and transgender women. Mitigation strategies to reduce virus transmission should be supplemented with measures to prevent depression and anxiety among marginalized populations, such as targeted economic relief and eHealth/mHealth interventions.

Polysubstance use in a community sample of Black cisgender sexual minority men and transgender women in Chicago during initial COVID-19 pandemic peak.

BACKGROUND: In response to COVID-19, the city of Chicago issued stay-at-home orders, which began on March 20, 2020, and restrictions meant to "flatten the curve" remained in effect until June 2, 2020. On June 3, 2020, Chicago entered the reopening phase. This study compares rates of polysubstance use by COVID-19 lockdown phase and across sociodemographic characteristics in a Chicago-based sample of Black cisgender sexual minority men (SMM) and transgender women. METHOD: Data come from the Neighborhood and Networks (N2) cohort, an ongoing study of Black cisgender SMM and transgender women living in Chicago. Participants (N = 226) completed a survey between April 20, 2020, and July 30, 2020, during the initial peak of the COVID-19 pandemic in Chicago. We conducted chi-square tests of independence and modified Poisson regression models with robust error variance and estimated adjusted prevalence ratios. RESULTS: Alcohol and marijuana were the most used substances, with 73.5% reporting at least one drinking day and 71.2% of the sample reporting marijuana use in the past 14 days. Tobacco was used by 41.6% of the sample, and illegal drug use, which does not include marijuana, was reported by 17.7% of the sample. Substance use was consistently associated with the use of other substances. As such, polysubstance use (i.e., using two or more substances) was common in this sample (63.7%). Few sociodemographic differences emerged, and substance use was not associated with lockdown phase. CONCLUSION: Substance use, including polysubstance use, was high in our sample of Black SMM and transgender women during the initial peak of the COVID-19 pandemic. Continued monitoring is needed given the duration of the COVID-19 pandemic and the negative health consequences associated with substance use in this population.

Sexual Identity, Sexual Behavior and Pre-exposure Prophylaxis in Black Cisgender Sexual Minority Men: The N2 Cohort Study in Chicago.

This study investigated sexual identity and behavior and their potential associations with PrEP use and attitudes in cisgender Black gay and bisexual men. A total of N = 173 (mean age 25.2) participants from the Neighborhoods and Networks (N2) Study in Chicago were included. Of these, 104 were gay-identified and reported sex with men only (GSMO), 26 were gay-identified and reported sex with men and women (GSMW), 8 were bisexual-identified and reported sex with men only (BSMO), and 35 were bisexual-identified and reported sex with men and women (BSMW). Reporting sex with men and women in the past 6 months, RR = 0.39, 95% CI [0.17, 0.89], identifying as bisexual, RR = 0.52, 95% CI [0.29, 0.92], and the combination of the two, RR = 0.24, 95% CI [0.07, 0.76] were significantly associated with lower rates of current oral PrEP use. Black bisexual-identifying men who reported sex with men and women were significantly more likely to have discontinued oral PrEP, RR = 2.50, 95% CI [1.14, 5.50], than Black gay-identified men who reported sex with men only. Participants who had not used oral PrEP before reported lower levels of interest in long-acting injectable PrEP than those who were currently using oral PrEP, RR = 0.56, 95% CI [0.40, 0.79]. No other significant differences were found. Overlooking the combination of sexual identity and behavior may mischaracterize PrEP rates and miss uniquely vulnerable subgroups. Black gay and bisexual men who had not used oral PrEP may be particularly disinterested in long-acting injectable PrEP.

Social-Environmental Resilience, PrEP Uptake, and Viral Suppression among Young Black Men Who Have Sex with Men and Young Black Transgender Women: the Neighborhoods and Networks (N2) Study in Chicago.

Young black men who have sex with men (YBMSM) and young black transgender women (TGW) have experienced a stark disparity in HIV prevention and care. Resilience, collective resources to adapt stressors or adversities, may improve HIV prevention and care outcomes. The present study investigated the association of resilience-based factors with PrEP uptake and viral suppression from a socioecological perspective among YBMSM and young black TGW. Data were from the baseline cycle of the Neighborhoods and Networks (N2) Study, an ongoing cohort study of 16-34-year-old YBMSM and young black TGW in Chicago (n = 324). Confidant network-level and neighborhood affiliation variables were created to measure the social-environmental context of resilience. All analyses were stratified by participants' HIV status (184 HIV-negative participants and 140 HIV-positive participants). Among HIV-negative participants, having a parental figure within an individual's confidant network was significantly associated with a greater likelihood of PrEP use. Among HIV-positive participants, confidant network members' awareness of an individual's HIV status was associated with viral suppression. Social support resources from confidant networks could improve HIV prevention and care engagement among YBMSM and young black TGW. Understanding the social and environmental contexts of resilience resource is critical for HIV prevention and care engagement.

The Motivational PrEP Cascade Guides Interpretation of Early PrEP Linkage to Care for Young Black Men Who Have Sex With Men: The Case of Chicago's PrEPLine.

Pre-exposure prophylaxis (PrEP) uptake remains low among Black men who have sex with men (BMSM). PrEPLine, launched in August 2015, based in Chicago, was designed to support PrEP linkage among BMSM. PrEPLine moves clients through the Motivational PrEP Cascade, addresses barriers, and tracks outcomes. Study findings suggest that three variables (i.e., being gay/same gender loving, living more than 15 miles from a clinic location, rescheduling an appointment) demonstrated a significant positive association with initiating PrEP. A subanalysis of BMSM found that two variables (i.e., living on the West Side of Chicago relative to those living on the South Side, and among those living in communities with a higher rate of poverty [more than 30%], relative to those living in communities with a lower rate of poverty [less than 20%]) demonstrated a significant negative association with initiating PrEP.

The Social Context of HIV Prevention and Care among Black Men Who Have Sex with Men in Three U.S. Cities: The Neighborhoods and Networks (N2) Cohort Study.

Background: In many parts of the world, stark racial disparities in human immunodeficiency virus (HIV) prevalence, incidence, prevention, and care outcomes persist among gay, bisexual, and other men who have sex with men (MSM), with Black MSM significantly impacted in the United States (U.S.). Individual-level characteristics, including sexual behaviors and socioeconomic status, do not fully account for racial/ethnic disparities in HIV among MSM. We hypothesize that neighborhood contexts and network characteristics influence risk for HIV infection as well as HIV-related prevention and care behaviors. As such, the study design includes the use of real-time geospatial methods and in-depth assessments of multiple network typologies to investigate the impact of neighborhood and network-level factors on HIV prevention and treatment among Black MSM residing in longstanding priority HIV elimination areas in the U.S., namely Chicago, Illinois and in the Deep South (Jackson, Mississippi and New Orleans, Louisiana) (n = 450, n = 50, and n = 100, respectively). We describe the design, sampling methods, data collection, data management methods, and preliminary findings of the ongoing 'Neighborhoods and Networks (N2) Cohort Study'. Methods/Design: N2 employs a prospective longitudinal design. The sample includes Black MSM participants in Chicago recruited via respondent-driven sampling and assessed every six months over two years of follow-up. Participants enrolled in Jackson and New Orleans are being recruited through existing health and community services and assessed every six months over one year of follow-up. Mobility within and between neighborhoods is being assessed using global positioning system (GPS) technology. Social and sexual networks among Black MSM are being studied through egocentric network inventories as well as newer methods of creating meso-level networks that involve social media (Facebook) and mobile phone contacts. Key HIV prevention outcomes such as pre-exposure prophylaxis (PrEP) care engagement, and HIV/STI (sexually transmitted infections) biomarkers will be examined at baseline and follow-up. Results: As of 31 December 2018, a total of 361 men were enrolled across all study sites: 259 in Chicago and 102 in the Deep South (75 in New Orleans and 27 in Jackson). At baseline, participants ranged in age from 17 to 65 years old (mean = 34.3, standard deviation = 5.1) with 123 men (34.1%) self-reported as HIV positive. While HIV treatment levels were similar between sites, men in the Deep South reported higher rates of adherence than men in Chicago (63.3% versus 49.4%, p = 0.03). Sexual risk profiles were mainly the same between men from different study sites, with 22.9% of men in Chicago and 28.9% in the Deep South reporting consistent condom use during vaginal and anal sex (p = 0.26). Regarding their home neighborhoods, men in the Deep South were more likely than those in Chicago to characterize theirs as having a good reputation (43.1% versus 24.7%, p < 0.001) and as being safe (37.3% versus 21.2%, p = 0.002). Conclusions: The focus on Black MSM in the N2 Study will allow for a nuanced exploration of the attitudes, beliefs, behaviors, and practices of a diverse group of Black MSM. The study is also positioned to provide novel insight about neighborhood and network characteristics that influence HIV-related behaviors. A health equity framework ensures that Black MSM are not explicitly or implicitly deemed as deviant, disordered, or the non-reference group. Findings from N2 will provide guidance for the implementation of more impactful HIV prevention interventions that engage a diverse population of Black MSM as we work toward HIV elimination in the U.S.

Gender Differences in HIV Testing, Diagnosis, and Linkage to Care in Healthcare Settings: Identifying African American Women with HIV in Chicago.

Women account for 25% of all people living with HIV and 19% of new diagnoses in the United States. African American (AA) women are disproportionately affected. Yet, differences in the care continuum entry are not well understood between patient populations and healthcare sites. We aim to examine gender differences in diagnosis and linkage to care (LTC) in the Expanded HIV Testing and Linkage to Care (X-TLC) program within healthcare settings. Data were collected from 14 sites on the South and West sides of Chicago. Multivariate logistic regression analysis was used to determine the differences in HIV diagnoses and LTC by gender and HIV status. From 2011 to 2016, X-TLC performed 281,017 HIV tests; 63.7% of those tested were women. Overall HIV seroprevalence was 0.57%, and nearly one third (29.4%) of HIV-positive patients identified were cisgender women. Of newly diagnosed HIV-positive women, 89% were AA. 58.5% of new diagnoses in women were made at acute care hospitals, with the remainder at community health centers. Women who were newly diagnosed had a higher baseline CD4 count at diagnosis compared with men. Overall, women had lower odds of LTC compared with men (adjusted odds ratio = 0.58, 95% confidence interval 0.44-0.78) when controlling for patient demographics and newly versus previously diagnosed HIV status. Thus, interventions that focus on optimizing entry into the care continuum for AA women need to be explored.

Project nGage: Results of a Randomized Controlled Trial of a Dyadic Network Support Intervention to Retain Young Black Men Who Have Sex With Men in HIV Care.

HIV-positive young black MSM (YBMSM) experience poor outcomes along the HIV care continuum, yet few interventions have been developed expressly for YBMSM retention in care. Project nGage was a randomized controlled trial conducted across five Chicago clinics with 98 HIV-positive YBMSM aged 16-29 between 2012 and 2015. The intervention used a social network elicitation approach with index YBMSM (n = 45) to identify and recruit a support confidant (SC) to the study. Each index-SC dyad met with a social worker to improve HIV-care knowledge, activate dyadic social support, and develop a retention in care plan. Each index and SC also received four mini-booster sessions. Control participants (n = 53) received treatment as usual. Surveys and medical records at baseline, 3-, and 12-months post-intervention assessed visit history (3 or more visits over 12 months; primary outcome), and sociodemographic, network, social-psychological, and behavioral factors. At baseline, there were no differences in age (M = 23.8 years), time since diagnosis (M ≤ 2 years), clinic visits in the previous 12 months (M = 4.1), and medication adherence (68.6 ≥ 90% adherence). In multivariate logistic regression analysis, intervention participants were 3.01 times more likely to have had at least 3 provider visits (95% CI 1.0-7.3) than were control participants over 12 months. Project nGage demonstrates preliminary efficacy in improving retention in care among YBMSM. Results suggest that engaging supportive network members may improve key HIV care continuum outcomes.

Multiple Dimensions of Stigma and Health Related Factors Among Young Black Men Who Have Sex with Men.

This study is among the first to examine the association between multiple domains of HIV-related stigma and health-related correlates including viral load and medication adherence among young Black men who have sex with men (N = 92). Individual logistic regressions were done to examine the hypothesized relationships between HIV-related stigma and various health and psychosocial outcomes. In addition to examining total stigma, we also examined four domains of HIV stigma. Findings revealed the various domains of stigma had differential effects on health-related outcomes. Individuals who reported higher levels of total stigma and personalized stigma were less likely to be virally suppressed (OR 0.96, 95 % CI 0.91-1.00 and OR 0.50, 95 % CI 0.25-1.02, respectively). Concerns about public attitudes toward HIV were positively related to medication adherence (OR 2.18, 95 % CI 1.20-3.94) and psychological distress (OR 5.02, 95 % CI 1.54-16.34). The various domains of HIV stigma differentially affected health and psychosocial outcomes, and our findings suggest that some forms of HIV stigma may significantly affect viral load and medication adherence among this population. Stigma-informed approaches to care and treatment are needed, along with incorporated psychological and social supports.

Expanded HIV Testing and Linkage to Care: Conventional vs. Point-of-Care Testing and Assignment of Patient Notification and Linkage to Care to an HIV Care Program.

OBJECTIVE: The University of Chicago Medicine (UCM) led the Expanded Testing and Linkage to Care (X-TLC) program for disproportionately affected populations on the South Side of Chicago. The X-TLC program aimed to expand routine HIV testing to high-prevalence communities with disproportionately affected populations (i.e., minority men and women, men who have sex with men, and intravenous drug users) according to CDC guidelines at multiple clinical sites. METHODS: The X-TLC program used standard blood-based laboratory testing vs. point-of-care rapid testing or rapid laboratory testing with point-of-care results notification. Site coordinators and the linkage-to-care coordinator at UCM oversaw testing, test notification, and linkage to care. RESULTS: From February 1, 2011, through December 31, 2013, the X-TLC program completed 75,345 HIV tests on 67,153 unique patients. Of the total tests, 48,044 (63.8%) were performed on patients who self-identified as African American and 6,606 (8.8%) were performed on patients who self-identified as Hispanic. Of the 67,153 patients tested, 395 (0.6%) tested positive and 176 (0.3%) were previously unaware of their HIV-positive status. Seroprevalence was even higher for EDs, where 127 of 12,957 patients tested positive for HIV (1.0% seroprevalence), than for other patient care sites, including for new diagnoses, where 50 of 12,957 patients tested positive for HIV (0.4% seroprevalence). Of the 176 newly diagnosed patients, 166 of 173 (96.0%) patients who were still alive when testing was complete received their test results, and 148 of the 166 patients who were eligible for care (89.0%) were linked to care. Patients linked to X-TLC physicians did well with respect to the continuum of care: 77 of 123 (62.6%) patients achieved HIV viral load of <200 copies/milliliter. CONCLUSION: Lead organizations such as UCM were able to assist and oversee HIV screening and linkage to care for HIV patients diagnosed at community sites. HIV screening and linkage to care can be accomplished by incorporating standard testing for HIV into routine medical care.

Implementing Routine HIV Screening in Three Chicago Hospitals: Lessons Learned.

OBJECTIVE: This study describes routine HIV screening implementation and outcomes in three hospitals in Chicago, Illinois. METHODS: Retrospective data from three hospitals were examined, and routine testing procedures, testing volume, reactive test results, and linkage-to-care outcomes were documented. RESULTS: From January 2012 through March 2014, 40,788 HIV tests were administered at the three hospitals: 18,603 (46%) in the emergency department (ED), 7,546 (19%) in the inpatient departments, and 14,639 (36%) in outpatient clinics. The screened patients varied from 1% to 22% of the total eligible patient population across hospitals. A total of 297 patients tested positive for HIV for a seropositivity rate of 0.7%; 129 (43%) were newly diagnosed and 168 (57%) were previously diagnosed, with 64% of those previously diagnosed out of care at the time of screening. The inpatient areas had the highest seropositivity rate (0.6%). The percentage of newly diagnosed patients overall who were linked to care was 77%. Of newly diagnosed patients, 51% had ≥ 1 missed opportunity for testing (with a mean of 3.8 visits since 2006), and 30% of patients with missed opportunities were late testers (baseline CD4+ counts <200 cells per cubic millimeter). CONCLUSION: Routine screening is an essential tool for identifying new infections and patients with known infection who are out of care. Hospitals need to provide HIV screening in inpatient and outpatient settings--not just EDs--to decrease missed opportunities. Routine screening success will be driven by how notification and testing are incorporated into the normal medical flow, the level of leadership buy-in, the ability to conduct quality assurance, and local testing laws.

Project nGage: Network Supported HIV Care Engagement for Younger Black Men Who Have Sex with Men and Transgender Persons.

BACKGROUND: Young Black men who have sex with men and transgender persons (YBMSMT) aged 13-29 carry the nation's highest burden of new HIV infections. Studies indicate that YBMSMT have poor retention in care, which is associated with reduced medication adherence and increased virologic failure. OBJECTIVE: Project nGage is a randomized controlled (RCT) trial evaluating the feasibility and preliminary efficacy of a brief, dyadic intervention designed to promote adherence to HIV primary care in safety-net clinics. Network visualization is used to identify and engage a support confidant (SC) from participants' social networks. A social work interventionist then meets with the SC and SC-participant dyad to activate and maintain HIV-specific social support. METHODS: Project nGage is operating in two phases. In Phase I, the Team refined study protocols based on pilot testing. In Phase II, 94 HIV infected YBMSMT ages 16-29 will be recruited, enrolled and randomly assigned to receive Project nGage or treatment as usual (TAU). The primary outcome is appointment attendance; the secondary outcomes are medication adherence and viral load. RESULTS: Implementation challenges include coordinating sites, managing dyadic intervention logistics, and recruiting non-adherent patients or those who have fallen out of care. The team continues to address implementation issues as the study progresses. CONCLUSIONS: Project nGage is addressing a gap in HIV care-related research by focusing on supportive relationships as a mechanism through which to promote retention in care. Pending study results, a larger RCT would compare the relative effectiveness of the Project nGage intervention versus TAU over 18 to 24 months.
