Role of Country of Birth, Testing Site, and Neighborhood Characteristics on Nonlinkage to HIV Care Among Latinos

Systematic Review of Neighborhood Factors Impacting HIV Care Continuum Participation in the United States

Social determinants have been increasingly implicated in accelerating HIV vulnerability, particularly for disenfranchised communities. Among these determinants, neighborhood factors play an important role in undermining HIV prevention. However, there has been little research comprehensively examining the impact of neighborhood factors on HIV care continuum participation in the US. To address this, we conducted a systematic review (PROSPERO registration number CRD42022359787) to determine neighborhood factors most frequently associated with diminished HIV care continuum participation. Peer-reviewed studies were included if published between 2013 - 2022, centralized in the US, and analyzed a neighborhood factor with at least one aspect of the HIV care continuum. The review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Study quality was guided by LEGEND (Let Evidence Guide Every New Decision) evaluation guidelines. Systematic review analysis was conducted using Covidence software. There were 3,192 studies identified for initial screening. Forty-four were included for review after eliminating duplicates, title/abstract screening, and eligibility assessment. Social and economic disenfranchisement of neighborhoods negatively impacts HIV care continuum participation among persons living with HIV. In particular, five key neighborhood factors (socioeconomic status, segregation, social disorder, stigma, and care access) were associated with challenged HIV care continuum participation. Race moderated relationships between neighborhood quality and HIV care continuum participation. Structural interventions addressing neighborhood social and economic challenges may have favorable downstream effects for improving HIV care continuum participation.

HIV Prevention Intervention-related Research with Adult, Sexual Minority Hispanic Men in the United States: A Systematic Review

The systematic review describes aims to synthesize the HIV prevention intervention-related research conducted among adult, US sexual minority Hispanic men since 2012. Following PRISMA guidelines, 15 articles representing 14 studies were included in the review: 4 randomized controlled trials, 5 pilots, and 5 formative projects. Two interventions had PrEP-related outcomes whereas 7 focused on behavioral (e.g., condoms, testing) and/or educational outcomes. Few studies used digital health. All but one study was theoretically guided. Community engagement was a common and important thread in the included studies, with community-based participatory research being the most prevalent framework. The inclusion of cultural factors varied widely, as did the availability of Spanish language or bilingual study materials. Future research opportunities are discussed and recommendations to bolster HIV prevention interventions (e.g., tailoring) are presented. These include the need for greater integration of cultural factors (e.g., nuances related to the heterogeneity of Hispanic subgroups) and mitigating critical barriers to help improve uptake of evidence-based strategies in this population.

A qualitative study of antiretroviral therapy adherence interruptions among young Latino men who have sex with men with HIV: Project D.A.I.L.Y

Consistent antiretroviral therapy (ART) adherence is necessary for HIV viral suppression. However, adherence may fluctuate around daily routines and life events, warranting intervention support. We examined reasons for ART adherence interruptions, using in-depth, semi-structured qualitative interviews, among young (18-34-year-old) Latino men who have sex with men (YLMSM) with HIV. Interviews (n = 24) were guided by the Theory of Planned Behavior, the Information-Motivation-Behavioral Skills Theory, and the Socio-Ecological Model. Two coders independently coded transcripts using NVivo 12 software and synthesized codes into themes using Thematic Content Analysis. Results suggested 4 primary influences on ART adherence interruptions: (1) HIV diagnosis denial, (2) breaks in daily routine, (3) substance use, and (4) HIV status disclosure. Participant quotes highlighted routinization of pill-taking and planning ahead for breaks in routine as critically important. The narrative suggested modification of pill-taking routines during alcohol use, and that periods most vulnerable for long-term interruptions in ART adherence were following an HIV diagnosis and during periods of drug use. Support at the time of HIV diagnosis, including a plan for routinization of pill taking, and adaptive interventions incorporating real-time support during breaks in routines and substance use episodes may be one way to help YLMSM adhere to ARTs.

Enacted HIV-Related Stigma's Association with Anxiety & Depression Among People Living with HIV (PLWH) in Florida

Research has shown that HIV-related stigma contributes to people living with HIV having a higher risk of mental health disorders. Our study examines the association between enacted HIV-related stigma and symptoms of anxiety and depression among PLWH. We used baseline data from 932 PLWH collected from the Florida Cohort study between 2014 and 2018. The sample was majority 45 + years of age (63.5%), male (66.0%), and Black (58.1%). The majority had previously experienced enacted HIV-related stigma (53.1%). Additionally, 56.6% and 65.2% showed mild to moderate/severe levels of anxiety and depression, respectively. Those who experienced any levels of enacted HIV-related stigma (vs none) had significantly greater odds of mild and moderate/severe levels of anxiety (vs no/minimal) (AOR[CI] 1.54[1.13, 2.10], p = 0.006; AOR[CI] 3.36[2.14, 5.26], p < 0.001, respectively) and depression (AOR[CI] 1.61[1.19, 2.18], p = 0.002; AOR[CI]  3.66[2.32, 5.77], p < 0.001, respectively). Findings suggest a need to evaluate interventions for PLWH to reduce the deleterious effects of enacted HIV-related stigma on mental health.

Disparities in Electronically Monitored Antiretroviral Adherence and Differential Adherence Predictors in Latinx and Non-Latinx White Persons Living with HIV

Antiretroviral therapy (ART) adherence is vital for optimal HIV treatment. However, there is limited ART adherence research on the US Latinx population, who are at increased risk for HIV infection and worse HIV health outcomes. This study examined electronically measured ART adherence (Medication Event Monitoring System) and its association with demographic, clinical, neurocognitive, and sociocultural variables in Latinx and non-Latinx white (NLW) persons living with HIV [PLWH (N = 128)]. Latinx participants demonstrated worse adherence than NLW participants (p = 0.04). Linear regressions revealed different predictors of adherence. Among Latinx participants, recent cocaine use, stress, and, unexpectedly, higher US acculturation predicted worse adherence (ps < 0.05). Among NLW participants, recent cocaine use predicted worse adherence (p < 0.05). Intergroup comparisons within the Latinx group were not conducted due to subsample size. Thus, ethnicity, sociocultural variables, and cocaine use are important considerations for ART adherence, and poor ART adherence may be one pathway explaining worse outcomes in Latinx PLWH. Culturally tailored adherence interventions incorporating substance use treatment, acculturation, and stress management are warranted to improve health outcomes.

Health Care-Specific Enacted HIV-Related Stigma's Association with Antiretroviral Therapy Adherence and Viral Suppression Among People Living with HIV in Florida

Among people living with HIV (PLWH) in Florida, <2/3 are virally suppressed (viral load <200 copies/mL). Previous theoretical frameworks have pointed to HIV-related stigma as an important factor for viral suppression; an important outcome related to the HIV continuum of care. This study aims to analyze the association between enacted HIV-related stigma and antiretroviral therapy (ART) adherence and viral suppression among a sample of PLWH in Florida. The overall sample (n = 932) was male (66.0%), majority greater than 45 years of age (63.5%), black (58.1%), and non-Hispanic (79.7%). Adjusted odds ratios (AOR) and 95% confidence intervals (CI) were estimated using logistic regression models. The odds of nonadherence to ART was not significantly greater for those reporting low/moderate or high levels of general enacted HIV-related stigma (vs. no stigma) [AOR = 1.30, CI: (0.87-1.95), p = 0.198; AOR = 1.17, CI: (0.65-2.11), p = 0.600, respectively]. Moreover, the odds of nonviral suppression were not significantly greater for those reporting low/moderate or high levels of general enacted HIV-related stigma (vs. no stigma) [AOR = 0.92, CI: (0.60-1.42), p = 0.702; AOR = 1.16, CI: (0.64-2.13), p = 0.622, respectively]. However, ever experiencing health care-specific enacted HIV-related stigma was associated with both nonadherence [AOR = 2.29, CI: (1.25-4.20), p = 0.008] and nonsuppression [AOR = 2.16, CI: (1.19-3.92), p = 0.011]. Despite limitations, the results suggest that the perpetuation of stigma by health care workers may have a larger impact on continuum of care outcomes of PLWH than other sources of enacted stigma. Based on the results, there is a need to develop and evaluate interventions for health care workers intended to reduce experienced stigma among PLWH and improve health outcomes.

"Holidays Come, Sundays Come. It is Very Sad to be Alone": Transnational Practices and the Importance of Family for Mexican and Puerto Rican Latinxs Living with HIV in the Continental U.S

Latinxs continue to be overrepresented in the U.S. HIV epidemic. We examined the transnational practices, family relationships, and realities of life of Mexicans and Puerto Ricans living with HIV in the continental U.S. We conducted qualitative interviews with 44 persons of Mexican and Puerto Rican origin participating in HIV care engagement interventions. Framework Analysis guided our data analysis. Among participants, a strong connection to the family was intertwined with transnational practices: communication, travel to their place of origin to maintain family ties, and material and/or emotional support. Separation from their family contributed to social isolation. Many participants lacked emotional support regarding living with HIV. Transnational practices and family relationships were intrinsic to the experiences of Mexicans and Puerto Ricans living with HIV in the continental U.S.; and may help understand the points of reference, health-seeking behaviors, and support sources that influence their health, well-being and engagement in HIV care.

HIV Care Outcomes among Hispanics/Latinos with Diagnosed HIV in the United States by Place of Birth-2015-2018, Medical Monitoring Project

Relocation from one’s birthplace may affect human immunodeficiency virus (HIV) outcomes, but national estimates of HIV outcomes among Hispanics/Latinos by place of birth are limited. We analyzed Medical Monitoring Project data collected in 2015–2018 from 2564 HIV-positive Hispanic/Latino adults and compared clinical outcomes between mainland US-born (referent group), Puerto Rican (PR-born), and those born outside the United States (non-US-born). We reported weighted percentages of characteristics and used logistic regression with predicted marginal means to examine differences between groups (p < 0.05). PR-born Hispanics/Latinos were more likely to be prescribed antiretroviral therapy (ART) (94%) and retained in care (94%) than mainland-US-born (79% and 77%, respectively) and non-US-born (91% and 87%, respectively) Hispanics/Latinos. PR-born Hispanics/Latinos were more likely to have sustained viral suppression (75%) than mainland-US-born Hispanics/Latinos (57%). Non-US-born Hispanics/Latinos were more likely to be prescribed ART (91% vs. 79%), retained in care (87% vs. 77%), and have sustained viral suppression (74% vs. 57%) than mainland-US-born Hispanics/Latinos. Greater Ryan White HIV/AIDS-funded facility usage among PR-born, better mental health among non-US-born, and less drug use among PR-born and non-US-born Hispanics/Latinos may have contributed to better HIV outcomes. Expanding programs with comprehensive HIV/AIDS services, including for mental health and substance use, may reduce HIV outcome disparities among Hispanics/Latinos.
