'Either You Float or You Drown:' The Role of Social Ties and Stigma in Lived Experiences of the HIV Care Continuum in HPTN 065

Social support needs of HIV-positive individuals reentering community settings from correctional facilities in Johannesburg, South Africa

Social networks and social support are important factors in medication adherence among people living with HIV (PLWH). Social networks can provide emotional, logistic, and material support leading to increased overall engagement in care. Certain populations of PLWH may have more limited access to social support, including those reentering community settings from correctional facilities. During periods of incarceration, social connections with family and friends may be frayed, reduced, or lost. This study, conducted in South Africa, explored the role of social support during community reentry among PLWH being released from correctional facilities. We conducted in-depth interviews with 41 community reentrants living with HIV. Qualitative analysis identified the challenges with establishing social support during reentry and the greater need for social support to remain engaged in HIV care in the community compared to in the correctional facility. These findings highlight challenges during community reentry and the importance of social support for these individuals.

Applying Behavioural Insights to HIV Prevention and Management: a Scoping Review

PURPOSE OF REVIEW

This scoping review summarises the literature on HIV prevention and management interventions utilizing behavioural economic principles encapsulated in the MINDSPACE framework.

RECENT FINDINGS

MINDSPACE is an acronym developed by the UK's behavioural insights team to summarise nine key influences on human behaviour: Messenger, Incentives, Norms, Default, Salience, Priming, Affect, Commitment, and Ego. These effects have been used in various settings to design interventions that encourage positive behaviours. Currently, over 200 institutionalised behavioural insight teams exist internationally, which may draw upon the MINDSPACE framework to inform policy and improve public services. To date, it is not clear how behavioural insights have been applied to HIV prevention and management interventions. After screening 899 studies for eligibility, 124 were included in the final review. We identified examples of interventions that utilised all the MINDSPACE effects in a variety of settings and among various populations. Studies from high-income countries were most common (n = 54) and incentives were the most frequently applied effect (n = 100). The MINDSPACE framework is a useful tool to consider how behavioural science principles can be applied in future HIV prevention and management interventions. Creating nudges to enhance the design of HIV prevention and management interventions can help people make better choices as we strive to end the HIV/AIDS pandemic by 2030.

"The role of case management in HIV treatment adherence: HPTN 078"

Adherence to care and antiretroviral therapy is challenging, especially for people living with HIV (PLWH) with additional co-occurring risk factors. Case management interventions, including motivational interviewing (MI), show promise to improve HIV treatment adherence, but few studies have examined how such interventions are delivered to or experienced by PLWH who have been reengaged in care. We conducted qualitative interviews with six case managers and 110 PLWH exiting from a randomized study (HPTN 078) who received a MI-based case management intervention in addition to standard patient-navigation services, or standard services only. Our study provided greater insight into the main findings from HPTN 078, including an in-depth description of the multiple barriers to adherence faced by this largely "out-of-care" population, as well as a more nuanced understanding of the benefits and challenges of implementing MI. A blend of MI plus more intensive interventions may be needed for PLWH facing multiple structural barriers.

Medical Mistrust and Stigma Associated with COVID-19 Among People Living with HIV in South Africa

We evaluated COVID-19 stigma and medical mistrust among people living with HIV in South Africa. We conducted telephone interviews with participants in a prospective study of a decentralized antiretroviral therapy program. Scales assessing medical mistrust, conspiracy beliefs, anticipated and internalized stigma, and stereotypes specific to COVID-19 were adapted primarily from the HIV literature, with higher scores indicating more stigma or mistrust. Among 303 participants, the median stigma summary score was 4 [interquartile range (IQR) 0-8; possible range 0-24] and 6 (IQR 2-9) for mistrust (possible range 0-28). A substantial proportion of participants agreed or strongly agreed with at least one item assessing stigma (54%) or mistrust (43%). Higher COVID-19 stigma was associated with female gender and antecedent HIV stigma, and lower stigma with reporting television as a source of information on COVID-19. Further efforts should focus on effects of stigma and mistrust on protective health behaviors and vaccine hesitancy.

Understanding Medical Distrust Among African American/Black and Latino Persons Living With HIV With Sub-Optimal Engagement Along the HIV Care Continuum: A Machine Learning Approach

Medical distrust is a potent barrier to participation in HIV care and medication use among African American/Black and Latino (AABL) persons living with HIV (PLWH). However, little is known about sociodemographic and risk factors associated with distrust. We recruited adult AABL PLWH from low socio-economic status backgrounds with insufficient engagement in HIV care (N = 512). Participants completed structured assessments on three types of distrust (of health care providers, health care systems, and counter-narratives), HIV history, and mental health. We used a type of machine learning called random forest to explore predictors of trust. On average, participants were 47 years old (SD = 11 years), diagnosed with HIV 18 years prior (SD = 9 years), and mainly male (64%) and African American/Black (69%). Depression and age were the most important predictors of trust. Among those with elevated depressive symptoms, younger participants had less trust than older, while among those without depression, trust was greater across all ages. The present study adds nuance to the literature on medical distrust among AABL PLWH and identifies junctures where interventions to build trust are needed most.

Examining stigma, social support, and gender differences in unsuppressed HIV viral load among participants in HPTN 065

Successful navigation of the HIV care continuum is necessary to maintain viral suppression. We explored gender-stratified correlates of being virally unsuppressed in the Prevention for Positives (P4P) component of HPTN 065. The outcome of interest was unsuppressed viral load (> 40 copies/mL) among individuals already living with HIV. Correlates included medication adherence factors, social support and stigma. Logistic regression models were stratified by gender (N = 673). Men-specific correlates of being virally unsuppressed included opposite-sex partners, older age and HIV disclosure stigma. Women-specific correlates included time since diagnosis, and personal-level barriers to medication adherence. When more individuals knew about their HIV status, women had over twice the likelihood of being virally unsuppressed; no such association was seen among men. Additionally, higher levels of social support were not associated with viral suppression among women. Interventions should consider gender-specific approaches to engaging social support in de-stigmatization of HIV and promotion of medication adherence and subsequent viral suppression.

Exploring individual-level barriers to HIV medication adherence among men who have sex with men in the HIV Prevention Trials Network (HPTN 065) study

African-American men who have sex with men (MSM) with HIV are more likely to have unsuppressed viral load than other racial/ethnic groups. HPTN 065 Study, completed in 2015, consisted of five interconnected study components conducted at clinics in Bronx, New York and Washington, D.C. Participants completed surveys with questions related to socio-demographic factors and individual-level HIV medication adherence barriers, such as forgetting doses or fear of taking medications in front of others. Descriptive analyses and ordinal logistic regression with robust standard errors were conducted. Fifty-seven per cent of participants (N = 359) were African-American (57.1%) and roughly 40% had no more than a high school education. Mean age was 48 years. Overall, MSM with viral load suppression identified fewer individual-level barriers to adherence (p < .01) and individuals with depressive symptoms identified a greater number of barriers to adherence (p < .01). Compared to African-Americans, white MSM had a lower likelihood of identifying barriers to adherence (p < .05). Findings suggest that individual-level barriers to HIV medication adherence are common among MSM, irrespective of time since diagnosis and viral suppression. Race-specific interventions which address intersectional stigma are needed to improve health outcomes among African-American MSM, who bear much of the burden of poor HIV outcomes in the United States.
