Social and Structural Factors Associated with Sustained Viral Suppression Among Heterosexual Black Men with Diagnosed HIV in the United States, 2015-2017

Food Insecurity Prevalence and Risk Factors among Persons with HIV in a Southeastern US Clinical Care Setting

Food insecurity (FI) is associated with adverse health outcomes for persons with HIV (PWH). Little is known about FI among PWH in southern or non-urban settings. We examined FI prevalence, risk factors, and access to services in a southeastern HIV clinic. Among PWH in the UNC CFAR HIV Clinical Cohort who were screened for FI as part of HIV care between 2021 and 2022, we estimated unadjusted prevalence ratios (PRs) comparing the probability of reporting FI by demographic and clinical characteristics. The 479 PWH screened for FI were 65% cisgender men, 62% non-Hispanic Black PWH, a median of 54 years old (IQR 41-62), and 93% with an HIV viral load (VL) < 200 copies/mL. FI prevalence was 36.3% (95% CI 32.3%-40.9%). Cisgender women and transgender adults were more likely to report FI than cisgender men (PRs 1.24 [95% CI 0.97-1.59] and 2.03 [1.32-3.12], respectively). Compared with White PWH, the PR was 1.71 (1.20-2.42) for Black and 2.44 (1.56-3.82) for Hispanic PWH. The PR was 1.42 (0.98-2.05) for PWH with VL ≥ 200 versus < 200 copies/mL. Having no or public versus private health insurance was also associated with FI. PWH with FI had a high prevalence of comorbidities including hypercholesterolemia (49%) and hypertension (48%), though these were not associated with FI. Almost half of PWH with FI were not accessing a food pantry or nutrition assistance program. Identifying FI in PWH is critical as FI is common and may contribute to viral non-suppression, poor comorbidity control, and gender and racial/ethnic health disparities in PWH.

Explaining racial and ethnic disparities in antiretroviral therapy adherence and viral suppression among U.S. men who have sex with men

OBJECTIVE

To identify factors - including social determinants of health (SDOH) - that explain racial/ethnic disparities in antiretroviral therapy (ART) adherence and sustained viral suppression (SVS) among U.S. men who have sex with men (MSM) with HIV.

DESIGN

We used weighted data from 2017-2021 cycles of the Medical Monitoring Project.

METHODS

Among MSM taking ART, we calculated prevalence differences (PDs) with 95% confidence intervals (CIs) of ART adherence (100% ART adherence, past 30 days) and SVS (all viral loads in past 12 months <200 copies/ml or undetectable) for Black MSM (BMSM) and Hispanic/Latino MSM (HMSM) compared with White MSM (WMSM). Using forward stepwise selection, we calculated adjusted PDs with 95% CIs to examine if controlling for selected variables reduced PDs.

RESULTS

After adjusting for age, any unmet service need, federal poverty level (FPL), food insecurity, homelessness, time since HIV diagnosis, gap in health coverage, and education, the BMSM/WMSM PD for ART adherence reduced from -16.9 to -8.2 (51.5%). For SVS, the BMSM/WMSM PD reduced from -8.3 to -3.6 (56.6%) after adjusting for ART adherence, age, homelessness, food insecurity, gap in health coverage, FPL, any unmet service need, time since diagnosis, and ER visit(s). The HMSM/WMSM PD for ART adherence reduced from -9.3 to -2.9 (68.8%) after adjusting for age and FPL. The unadjusted HMSM/WMSM PD for SVS was not statistically significant.

CONCLUSIONS

Adjusting for SDOH and other factors greatly reduced racial/ethnic disparities in ART adherence and SVS. Addressing these factors - particularly among BMSM - could substantially improve health equity among MSM with HIV.

Associations between psychosocial factors and antiretroviral therapy outcomes differ by gender and sexual orientation among people living with HIV in British Columbia, Canada

Little is known about how the co-occurrence of psychosocial factors affect sub-populations of people living with HIV (PLWH). We used cross-sectional data from 999 PLWH, aged ≥19, accessing antiretroviral therapy (ART) in British Columbia, Canada (2007-2010) to examine associations between psychosocial factors and ART-related outcomes separately for trans/cis inclusive women; heterosexual men; and gay, bisexual, and other men who have sex with men (gbMSM). Multivariable logistic regression examined associations between psychosocial factors (0-3): any violence in the past 6 months, depressive symptoms in the past week, and current street drug use (heroin, crack, meth or speedball) with sub-optimal adherence (outcome 1: average annual ART adherence <95% from interview until end of follow-up, death, or December 31st, 2018) and ever viral rebound (outcome 2) adjusting for potential confounders. Of 999 PLWH (264 women, 382 heterosexual men, and 353 gbMSM), women and heterosexual men had significantly higher median counts than gbMSM. Overall, higher counts were associated with sub-optimal adherence (adjusted odds ratio [aOR] = 1.26/1-unit increase, 95%CI = 1.07-1.49). All effect estimates were of a greater magnitude among gbMSM, but not significant for women or heterosexual men, highlighting the need for population (e.g., gender and sexual orientation)-centered care and research.

Effect of Social Determinants of Health on Uncontrolled Human Immunodeficiency Virus (HIV) Infection Among Persons With HIV in San Francisco, California

Background

In 2010-2014, the San Francisco Department of Public Health (SFDPH) established programs to rapidly link people with human immunodeficiency virus (PWH) to care and offer antiretroviral therapy (ART) at human immunodeficiency virus (HIV) diagnosis. Such programs reduced the number of PWH out of care or with detectable HIV viral load (ie, uncontrolled HIV infection). We investigated the role of social determinants of health (SDH) on uncontrolled HIV.

Methods

Cross-sectional data from adult PWH diagnosed and reported to the SFDPH as of December 31, 2019, prescribed ART, and with confirmed San Francisco residency during 2017-2019 were analyzed in conjunction with SDH metrics derived from the American Community Survey 2015-2019. We focused on 5 census tract-level SDH metrics: percentage of residents below the federal poverty level, with less than a high school diploma, or uninsured; median household income; and Gini index. We compared uncontrolled HIV prevalence odds ratios (PORs) across quartiles of each metric independently using logistic regression models.

Results

The analysis included 7486 PWH (6889 controlled HIV; 597 uncontrolled HIV). Unadjusted PORs of uncontrolled HIV rose with increasingly marginalized quartiles, compared to the least marginalized quartile for each metric. Adjusting for demographics and transmission category, the POR for uncontrolled HIV for PWH in the most marginalized quartile remained significant across metrics for poverty (POR = 2.0; confidence interval [CI] = 1.5-2.6), education (POR = 2.4; CI = 1.8-3.2), insurance (POR = 1.8; CI = 1.3-2.5), income (POR = 1.8; CI = 1.4-2.3), and income inequality (POR = 1.5; CI = 1.1-2.0).

Conclusions

Beyond demographics, SDH differentially affected the ability of PWH to control HIV. Despite established care programs, PWH experiencing socioeconomic marginalization require additional support to achieve health outcome goals.

Perspectives on preparing for long-acting injectable treatment for HIV among consumer, clinical and nonclinical stakeholders: A qualitative study exploring the anticipated challenges and opportunities for implementation in Los Angeles County

Long-acting injectable (LAI) antiretroviral therapy (ART) is a novel HIV treatment option for people with HIV. The first LAI ART regimen for HIV treatment received regulatory approval in the United States in January 2021. In February 2020, we collected qualitative data from 18 consumers and 23 clinical and non-clinical stakeholders to catalog anticipated individual-consumer, healthcare system, and structural levels barriers and facilitators to LAI ART implementation in Los Angeles County, California. Thematic analysis was guided by the CFIR implementation science model. CFIR constructs of intervention characteristics, individual characteristics, outer and inner setting, intervention characteristics, and implementation process emerged in analysis. Under intervention characteristics, anticipated facilitators included the relative advantage of LAI ART over pills for adherence and reduced treatment management burden and related anxiety; anticipated barriers included non-adherence to injection appointments, concerns of developing HIV resistance, discomfort with injection and cost. Anticipated facilitators based on individual characteristics included overall acceptability based on knowledge and positive beliefs about LAI ART. Participant noted several characteristics of the outer setting that could negatively impact implementation, such as medical mistrust, external policies, and LAI ART eligibility (i.e., to be virally suppressed prior to initiation). Participants were optimistic about the potential to decrease stigma but expressed that provider willingness for adoption could be hindered by challenges in organizational inner setting related to payment authorizations, increased staffing needs, medication procurement and storage, and provider and healthcare system readiness. Results from this pre-implementation study may inform rollout and scale-up of LAI ART in Los Angeles County.

Examining Interprofessional Collaboration across case managers, peer educators, and counselors in New York City

Many individuals who are vulnerable to HIV infection and People Living with HIV (PLWH) experience fragmented prevention and care. Prevention and care service integration, pivotal for the HIV care continuum, depends on relationships among service providers and agencies offering HIV services. Case managers, counselors, and peer educators often work together to provide integrated services through interprofessional collaboration (IPC) in HIV prevention and care. Although these providers have distinct job titles, they typically offer complementary services on the HIV care continuum. To better train and allocate professional development resources for these providers, research is needed to assess the overall differences between provider-type and their demographics, intrapersonal factors, and job characteristics most likely to predict IPC engagement. We administered a cross-sectional survey to 75 counselors, 80 peer educators, and 112 case managers in 36 agencies in New York City. We performed a series of linear mixed effects models. Most of the HIV-service providers identified as Black and female and had been working for their agencies for less than a year. Knowledge and skills, self-efficacy, understanding of the community, and greater work hours (> 35 hours) were significant predictors of endorsement of IPC. Peer educators compared to case managers were more likely to reflect on the process as they provide myriad services. Eliciting perspectives from providers allows us to explore interventions, both intra-agency (trainings, greater exposure to collaborative initiatives, and supervision) and interagency (retention programs and websites promoting provider collaboration), that could facilitate IPC engagement and integrated services across the HIV care continuum.
