Pre- and Post-immigration HIV Testing Behaviors among Young Adult Recent Latino Immigrants in Miami-Dade County, Florida

Assessing Structural Racism and Discrimination Along the Pre-exposure Prophylaxis Continuum: A Systematic Review

Structural racism and discrimination (SRD) is deeply embedded across U.S. healthcare institutions, but its impact on health outcomes is challenging to assess. The purpose of this systematic literature review is to understand the impact of SRD on pre-exposure prophylaxis (PrEP) care continuum outcomes across U.S. populations who could benefit from HIV prevention. Guided by PRISMA guidelines, we conducted a systematic review of the published literature up to September 2023 using PubMed and PsycInfo and included peer-reviewed articles meeting inclusion criteria. At least two authors independently screened studies, performed quality assessments, and abstracted data relevant to the topic. Exposure variables included race/ethnicity and any level of SRD (interpersonal, intra- and extra-organizational SRD). Outcomes consisted of any steps of the PrEP care continuum. A total of 66 studies met inclusion criteria and demonstrated the negative impact of SRD on the PrEP care continuum. At the interpersonal level, medical mistrust (i.e., lack of trust in medical organizations and professionals rooted from current or historical practices of discrimination) was negatively associated with almost all the steps across the PrEP care continuum: individuals with medical mistrust were less likely to have PrEP knowledge, adhere to PrEP care, and be retained in care. At the intra-organizational level, PrEP prescription was lower for Black patients due to healthcare provider perception of higher sex-risk behaviors. At the extra-organizational level, factors such as homelessness, low socioeconomic status, and incarceration were associated with decreased PrEP uptake. On the other hand, healthcare provider trust, higher patient education, and access to health insurance were associated with increased PrEP use and retention in care. In addition, analyses using race/ethnicity as an exposure did not consistently show associations with PrEP continuum outcomes. We found that SRD has a negative impact at all steps of the PrEP care continuum. Our results suggest that when assessing the effects of race/ethnicity without the context of SRD, certain relationships and associations are missed. Addressing multi-level barriers related to SRD are needed to reduce HIV transmission and promote health equity.

Barriers and facilitators to PrEP use and HIV testing for subgroups of Latino sexual minority men

Pre-exposure prophylaxis (PrEP) and HIV testing inadequately reach Latino sexual minority men (LSMM), fueling HIV disparities. This study identified determinants of LSMM's PrEP use and HIV testing and examined differences across subgroups (i.e., age and immigration history). First, we identified the most to least endorsed barriers and facilitators of PrEP use and HIV testing among LSMM (1) over vs. under 40 years old, and (2) across immigration histories (U.S. born, recent immigrant, established immigrant). Next, we examined differences in barrier/facilitator ratings across these age and immigration status groups. Key overall determinants were cost, knowledge, and perceived benefit/need. However, there was variation in determinants across age groups (i.e., cost, affordability, navigation support, and normalization) and immigration statuses (i.e., language, immigration concerns, and HIV knowledge). There were also differences across service types; mistrust and concerns was a barrier related to PrEP but not HIV testing. We found unique and common multilevel factors across prevention services and subgroups. Language, cost, and clinic/system issues are key barriers in accessing HIV prevention that should be considered when developing implementation strategies to enhance the reach of these services to LSMM.

Early trajectories of cigarette and ENDS use among young adult recent Latino immigrants to U.S

Background: Recent Latino immigrants (RLIs) to the U.S. have shown high smoking rates during their first year since arrival, raising concern about future escalation of tobacco use.Objective: To examine trajectories of cigarette and Electronic nicotine delivery systems (ENDS) use among RLIs from pre-immigration (T0) through their first (T1) and second (T2) year in the U.S.Methods: Data originated from a longitudinal study of 540 (50% females) RLIs aged 18-34. Inclusion criteria was residing in Miami/Dade County (MDC), and having immigrated from a Latin American country within the past year. Trajectories were identified by using the Proc Traj procedure (SAS©, v 9.4).Results: Rates of cigarette use per month declined from 11.8 days/month in T0 to 4.9 d/m in T2. Rates for ENDS use however, increased from T0 (1.1 d/m) to T1 (1.8 d/m) and then lowered back to 0.9 d/m in T2. Four separate cigarette and e-cigarette use trajectories were identified. Only one of them showed increase in cigarette (10.6% of RLIs), and ENDS use (4.5% of RLIs). Being male, and not completing high school were significant factors in explaining smoking trajectories. Being younger than 30 years old was largely associated with ENDS use. No evidence of a substitution effect between cigarette and ENDS use was found.Discussion/Conclusions: Interventions to discourage tobacco use among Latino immigrants should begin early in the immigration process, aimed to preserve initial reductions and dissuade those at risk of increased tobacco use overtime.
