Background: Surveillance points to an urgent public health need for HIV prevention, access, and retention among young men of color who have sex with men (YMSM). The purpose of this multisite study was to evaluate the association between organizational- and individual-level characteristics and retention in HIV care among HIV-positive YMSM of color.
Methods: Data were collected quarterly via face-to-face interviews and chart abstraction between June 2006 and September 2008. Participants were aged 16-24 years, enrolled at 1 of 8 participating youth-specific demonstration sites, and engaged or reengaged in HIV care within the last 30 days. Generalized estimating equations were used to examine factors associated with missing research and care visits. Stata v.9.0se was used for analysis.
Results: Of 224 participants, the majority were African American (72.7%), 19-22 years old (66.5%), had graduated high school or equivalent (71.8%), identified as gay or homosexual (80.8%), and disclosed having had sex with a man before HIV diagnosis (98.2%). Over the first 2¼ years of the study, only 11.4% of visits were missed without explanation or patient contact. Characteristics associated with retention included being <21 years old, a history of depression, receipt of program services, and feeling respected at clinic; those associated with poorer retention included having a CD4 count <200 at baseline and being Latino.
Conclusions: Special Projects of National Significance programs were able to achieve a high level of retention over time, and individual and program characteristics were associated with retention. Latino YMSM, those not receiving services, and those not perceiving respect at the clinic were at increased risk of falling out of care. Retention is essential to providing HIV+ adolescents with treatment, including reducing antiretroviral resistance development. Innovative programs that address the needs of the YMSM of color population may result in improved retention.
Surveillance data point to an increasing public health need for HIV prevention, access, and retention in care among young men of color who have sex with men (YMSM). Among adolescents diagnosed with HIV/AIDS through 2006 in the United States, 64% were attributed to men who have sex with men (MSM) behavior with an increased proportion among adolescents.1,2 Between 2001 and 2006, MSM aged 13-24 years had the greatest proportional increase in cases; of those adolescents, black YMSM experienced a 93% increase in HIV/AIDS.1,2 YMSM of color have also shown an increased risk of unrecognized HIV infection.3-5 For example, the Young Men's Survey found that a substantial proportion of black MSM participants were unaware of their HIV status.6
Adolescence presents unique challenges to linkage and retention in HIV care for YMSM of color. The added facets of sexual orientation and gender identity development, homophobia, racism, poverty, stigmatization, and developmental proclivity toward risk taking result in frequent marginalization of minority MSM, which can create barriers to care.3,5-21 HIV facilities may not be culturally or age appropriate, have specialty staff, and accommodate bilingual needs for Latino youth or other characteristics sufficient to address the adolescent's unique and constantly changing needs.3,5-21 Youth have been found to be less likely to return for HIV test results, reducing opportunity for harm reduction or access to care; African American MSM and MSM with other high-risk behaviors are often the least likely to return and the most likely to be unaware of their HIV-positive status.3,5-21
More information is needed about YMSM of color to create innovative effective prevention and care services. Such models are critical for nonwhite YMSM not already receiving HIV prevention or treatment services. HIV-positive youth are more likely to “fall through the cracks”10 and have been described as a “special type of hidden population”7 requiring unique case finding strategies, with distinctive program characteristics that engage and retain youth.7 These novel strategies may include case management and care programs that actively engage adolescents and young adults in youth-friendly environments while recognizing their needs through the stages of develoment.7,10,14,15 Specialized services may also be better able to provide the support youth need to remain on antiretroviral treatment. Given that the risk of viral resistance is increased in the face of poor adherence to treatment, the need for such services becomes more pronounced among subpopulations of youth at risk.
To expand on findings of an earlier multisite study on adolscents,7 the Health Resources Services Administration HIV/AIDS Bureau funded 8 demonstration sites and 1 evaluation center in 2003 for a 5-year Special Projects of National Significance (SPNS). The objective of the initiative was to identify innovative strategies for outreach, linkage, entry, and retention in care for HIV-positive YMSM of color, primarily those out of care or not accessing prevention or treatment services or other research. The purpose of this study was to examine characteristics of participants and associations between program delivery and retention in care.
Participants were enrolled at 1 of 8 SPNS-funded demonstration sites (Bronx, NY; Chapel Hill, NC; Chicago, IL; Detroit, MI; Houston, TX; Los Angeles, CA; Oakland, CA; and Rochester, NY), each with its own outreach, linkage, and retention strategy. Interventions at the sites varied based on local standards and the selected program under evaluation. The projects are described in Table 1. Two involved intensive case management provided to YMSM, 1 used motivational interviewing to increase HIV testing and return for results, 2 developed youth-centered support environments with groups and educational offerings, 2 used youth organizer/enhanced organizational outreach approach, and 1 was a statewide YMSM outreach initiative. All sites were required to enhance linkages with primary care providers with experience in HIV+ youth, and most collaborated closely with them on a regular basis. One consistent characteristic was that all the programs were specific to the YMSM of color population. In addition, each had at least 1 newly developed adolescent feature, such as adolescent medicine specialists, youth environment, support groups, peer outreach/navigation, waiting room redesign, outreach/care linkages, and/or social marketing.
One evaluation and support center was funded to assist local evaluations and conduct a multisite evaluation. To be eligible for the prospective multisite study from which these data were drawn, participants had to be: (a) male (biologically born male or female-born individuals who selfidentify as male), (b) HIV+, (c) diagnosed HIV+ within the past 30 days or reengaged in care in the past 30 days after being out of care for at least 6 months, (d) a male who had sex with males or had intent/wish to have sex with males, (e) selfidentified as nonwhite, (f) between 13 and 24 years at the time of the first interview, and (g) able to provide written informed consent. Eligible participants were administered a standardized face-to-face interview by local study staff at baseline and every 3 months thereafter. Data collected between June 2006 and September 2008 were analyzed. The questionnaire was adapted from standardized tools, including the Young Men's Survey, the Youth Risk Behavior Survey, National HIV Behavioral Surveillance tools, the HIV Cost and Service Utilization Study, previous SPNS instruments, and Adolescent Trials Network questions. Clinical data were abstracted by local staff. De-identified data were entered into a secure web-based data portal by study staff and analyzed by evaluation center faculty. All participants provided written informed consent to participate in the study. All instruments and protocols were approved by Health Resources Services Administration/HIV/AIDS Bureau/SPNS, local Institutional Review Boards (IRBs), and the George Washington University IRB.
Uni- and bivariate analyses were used to describe participants and potential confounders. Multivariable methods were used to describe characteristics associated with being unable to reach the participants at any quarterly visit. This outcome was chosen to assess program ability to prevent falling out of the system for any 3-month period. If the participant had contact with any part of the program-medical, program, or other ancillary care, even if not the research visit-he was not considered to have missed the visit. Medical or otherwise explained absences were not counted as negative outcomes. Generalized estimating equations (GEE) were used to assess associations between independent variables and missing the visit. GEE allows analysis of associations between the predictors under study (individual- and program-level characteristics) and low retention in the study and clinic after adjusting for confounders and the effect of time; it also allows reduction in variance attributable to the intraperson correlation between the multiple visit time points.22-24 An exchangeable correlation structure and robust estimators of variance were used; parameter estimates were exponentiated to provide odds ratios (OR) and confidence intervals (CI). Exact time was used in the model as the time variable. Multivariable models were developed by conducting a bivariate screening procedure; variables that were moderately associated (P < 0.25) with the outcome were eligible for inclusion in the model. A backward stepwise procedure was then used, with significant (P < 0.05) variables and known confounders and predictors of interest left in the model. Potential confounders were reentered into the model, and the model was checked for alteration (>5%) in the coefficients to ensure that residual confounding was not missed. All 2-way interactions were assessed for significance. Stata software, version 9.0SE (Stata Corporation, College Station, TX) was used for analysis.
Baseline characteristics of study participants are described in Tables 2 and 3. Of the 224 clients enrolled in the study, the majority were African American (72.7%), 19-22 years of age (66.5%), selfidentified as gay or homosexual (80.8%), and had high school equivalency or beyond (71.8%) at the time of the baseline interview. Almost all disclosed having had sex with a man before HIV diagnosis (98.2%), and most (92.2%) were comfortable with their sexual orientation. The majority (94.2%) were identified as male, with the remainder a combination of female, transgender, transsexual, “realness” (a participant-defined term often part of the house/ball culture), butch or femme queen, or cross-dresser.
Before being referred into the SPNS projects, nearly a quarter (24.8%) of participants first tested HIV+ at a clinic or doctor's office and 60.3% at other health care facilities. At baseline, 12.2% had an absolute CD4 <200 and 35.8% had an HIV viral load >100,000 copies per milliliter. Nearly a quarter (24.9%) had received routine health care in the last 3 months, whereas 18.3% had been seen in an emergency room in the last 3 months and 10.7% had been hospitalized. By protocol, the baseline interview took place within 30 days of being engaged or reengaged in care; most participants (84.4%) were able to complete their first HIV care visit by the time the baseline interview took place. The mean time to enter care was 1.37 months after first HIV+ result (SD 2.51, median 0.46 months), with the range of 0.03-17.89 months. A fifth (19.6%) of participants were reengaged in care after an absence of more than 6 months.
As shown in Table 2, drug and alcohol use were common, with 72.3% of participants ever having used marijuana and 66.1% ever having used other drugs (eg, heroin, cocaine, painkillers, and hallucinogens); 58.7% drank alcohol at least 1 day out of the last 14, including 57.2% of participants under 21 years of age. Nearly half (47.4%) cited problems associated with drug or alcohol use in the last 3 months. Condom use at last sex varied based on type of sex, but the majority (77.7%) reported condom use at last anal sex. Condom use varied based on behavior, with a low of 32.3% at last receptive oral sex to a high of 79.2% for insertive anal sex. Participants reported having experienced a substantial variety of negative situations. These included running out of money for basic needs in the last 3 months (86.2%), witnessing ambient violence (77.5%), seeing someone attacked with (33.2%) or killed with a gun (13.2%), and fear of violence (19.9%). Participants also had lifetime histories frequently including violence due to their race (19.0%) or sexuality (54.4%) and reported high rates of ever being depressed (36.1%), attempting suicide (14.0%), and experiencing emotional or physical abuse (70.9%). On the Center for Epidemiologic Studies-Depression index, 50.2% scored above the cut point, demonstrating depressive symptomatology (≥16).
The programs maintained high levels of participation: only 11.5% of all quarterly follow-up visits were missed for unknown reasons, suggesting an 88.9% retention rate. This missed visit rate included all visits in which both the study and the clinic visits were missed, and the participant could not be contacted for up to 6 weeks after the scheduled visit. There were no significant differences in retention between demonstration sites. As shown in Table 4, the aggregate level of participants responding to the question “… Did any of these things help you keep your HIV-related medical care appointments in the last 3 months?” increased significantly in the following: transportation increased to 53.3% at follow-up vs. 43.3% at baseline, appointment reminders 77.3% vs. 62.0%, concrete items at visit (eg, food, incentive, and phone card) 27.5% vs. 10.2%, flexible scheduling 72.7% vs. 58.3%, other services (eg, support group and case management) 40.7% vs. 27.3%, and feeling respected by the provider 66.7% vs. 55.1%.
There were significant differences between groups perceiving respect at the clinic, with African American youth more likely than others to feel respected (OR: 1.73, 95% CI: 1.10 to 2.75, P < 0.02), as were those with parental insurance (OR: 1.68, 95% CI: 1.04 to 2.72, P < 0.04) and those in school (OR: 1.66, 95% CI: 1.09 to 2.53, P < 0.02). Latino youth were significantly less likely to feel respected at the clinic (OR: 0.63, 95% CI: 0.40 to 0.98, P < 0.04). Similarly, there were significant differences between groups receiving program services: those in school (OR: 3.54, 95% CI: 1.50 to 8.30, P < 0.05) and work (OR: 16.23, 95% CI: 6.41 to 41.05, P < 0.001) were more likely to receive services, and those experience depressive symptoms at baseline were less likely to receive program services (OR: 0.40, 95% CI: 0.18 to 0.89, P < 0.03). Those with viral loads at baseline >10,000 vs. ≤ 10,000 were more likely to receive concrete items (OR: 1.79, 95% CI: 1.08 to 3.00, P < 0.03), although there were no other significant differences seen between those receiving and not receiving services or concrete items.
As shown in Table 4, after adjustment for baseline age and CD4 count, receipt of any program service (OR: 0.16, 95% CI: 0.03 to 0.92) and feeling respected at the clinic (OR: 0.06, 95% CI: 0.006 to 0.58) were associated with being less likely to miss a visit, whereas having other additional concrete item (eg, food and phone card) at the clinic was associated with being more likely to miss a visit (OR: 10.36, 95% CI: 1.23 to 87.36). As shown in Table 5, after adjustment, younger age (<21 years) (OR: 0.09, 95% CI: 0.01 to 0.74) and ever feeling depressed (OR: 0.15, 95% CI: 0.03 to 0.74) were associated with being less likely to miss a visit. Having a lower CD4 count (<200) (OR: 4.46, 95% CI: 1.05 to 18.90) and being Latino (OR: 3.85, 95% CI: 1.15 to 12.88) were associated with being more likely to miss a visit.
This study of newly engaged in care HIV-positive YMSM of color reveals that despite the challenges that this population experiences on a day-to-day basis, YMSM of color may successfully be retained in care and in research. Latino youth may need further specialized ancillary care: even within youth-focused programs such as these, they were more likely to encounter barriers to staying in care and were less likely to perceive positive elements of the clinic environment, such as feeling respected. As has been seen by other authors,6-14,19,21,25 HIV+ YMSM of color often face multifaceted profound challenges. These include parental abuse, substance abuse, depression, violence, stigmatization, poor access to medical care, and evolving gender identity and sexual orientation issues, all against the backdrop of adolescent developmental changes. However, even the YMSM in this study considered difficult to reach with active retention procedures; only 11.4% of visits were completely missed over the study period to date-an acceptable attrition rate.
This study found that there were several program-level factors associated with retention, including, perhaps most importantly, feeling respected at the clinic and receiving program services. Feeling respected may have emerged as a result of the wide variety of youth-focused services, including flexible scheduling, having accompaniment to clinic, transportation, appointment reminders, liking the providers, and having colocated services. Uptake of all these services increased over time, and service receipt was associated with increased retention.
Concrete item receipt was associated with reduced retention, although this may be an artifact of the association found between provision of these and high viral loads and current enrollment in school (which is associated with being younger age). YMSM in both of those categories may have presented increased challenges for retention and thus precipitated provision of the concrete items. The concrete items were distinct from receipt of program receipt, which was associated with increased retention although it is not possible to separate the availability of services at the site with the program itself. Whereas younger participants and those with increased depressive symptomatology were actually more likely to be retained, participants with lower CD4 counts at baseline and Latino YMSM were less likely to be. It may be that sicker participants who access care later need additional or differentiated support from those identified earlier in the disease process. In addition, the SPNS project did not have Latino-specific approaches. Latino youth often experience very different family and social contexts, which may necessitate additional approaches, even within programs providing minority YMSM care. For example, Latino ethnicity has been associated with late HIV testing; our finding that Latino YMSM were at increased risk of falling out of care may emphasize the need for specific cultural approaches for Latino YMSM. The finding that depression was linked to increased retention suggests that youth-specific services can actively engage depressed youth and devote special case management to those in need. This approach of identifying depressed youth and treating them may result in increased retention of those most at-risk youth.
There are several limitations to this study. SPNS initiatives examine innovative approaches to retention and care for HIV+ youth; as a result, each of the 8 participating sites had a unique program, rendering it difficult to compare interventions despite common evaluation methodology. As with all questionnaires, information bias presents a particular concern, subject to interviewer, recall, social desirability, and other biases. Computer techniques have been shown to effectively reduce such biases among some populations, but among adolescents, there have been mixed findings.26-34 Due to resource constraints, a computer-assisted selfinterview approach was not feasible. The high rates of depression, suicidality, and substance abuse reported suggest that participants were candid with interviewers. Whereas training and data collection quality checks were centralized, supervision and quality assurance were provided and overseen locally, which may have introduced increased variability in data quality, although this was not observed statistically. Finally, this was a convenience sample; thus, these findings may not be generalizable.
This study has several strengths. Unlike other studies of adolescents, this study focused on enrolling individuals not already in HIV care who had multiple barriers to access, including being young, HIV+, belonging to a minority group, and MSM; all were newly engaged or reengaged in care. Thus, this cohort represents harder to reach adolescents and sought to identify what were effective means of keeping them in the program. Another strength was the diversity in site locations throughout the country with different program approaches. As a longitudinal design, with GEE, this study allowed examination of changes over time related to baseline and time-varying covariates, including service delivery.
As HIV/AIDS continues to affect African American and Latino YMSM populations, it is becoming increasingly important to develop, implement, and evaluate innovative approaches to linking and retaining them in care. Adolescents effectively engaged in care are more likely to adopt harm reduction behaviors and to reduce their own risks-not only for HIV-related illness but also for concomitant conditions such as mental illness, substance abuse, and socio-environmental challenges-and increase secondary prevention behaviors. YMSM of color are at particular risk of threats to mental health and substance abuse, and unique approaches to addressing their needs are required. This initiative suggests that YMSM of color can be treated neither like children nor like adults: unique age- and developmental-specific interventions must be created for them. These, in turn, need to be customized for the needs of young MSM of color and also be culturally appropriate for the population being served. Innovative approaches may need to provide for the cultural context of Latino youth individually and those youth more progressed in their HIV disease. Without careful attention paid to the needs of the population, ensuring retention of those in care will not happen. Future study is needed to improve program offerings and to develop additional innovative approaches to supporting HIV+ YMSM of color.
