Stigmatization of food insecurity helps explain the association between food insecurity and medication nonadherence among people living with HIV

Food insecurity is an established barrier to antiretroviral therapy (ART) adherence among people living with HIV (LWHIV). While insufficient access to food reliably impedes medication adherence, the link between food insecurity and ART nonadherence has not been fully explained. In addition, depression is reliably associated with both food insecurity and ART nonadherence, but again the link between food insecurity and depression is not understood. A potential explanatory mechanism in the associations among food insecurity, depression and ART nonadherence is the experience of food insecurity stigma (FI-stigma). The current study tested FI-stigma in relation to depression as explanatory mechanisms in the association between food insecurity and ART nonadherence. Men and women (n = 495) LWHIV in the southeastern United States completed confidential surveys that included measures of food insecurity, FI-stigma, depression, and ART adherence. Results from the serial mediation model indicated significant direct effects of food insecurity and depression on ART adherence. In addition, food insecurity was indirectly associated with ART adherence through FI-stigma and depression symptoms. Results suggest that the stigmatization of food insecurity predicts increased depression which in turn predicts ART nonadherence, with both FI-stigma and depression symptoms partially mediating the relationship between food insecurity and ART nonadherence. Interventions aimed to reduce food insecurity should include it's associated stigma to improve treatment adherence among people LWHIV.

The three-item patient-reported instrument for retrospective adherence in resource constrained settings: reliability, validity and potential utility

INTRODUCTION

Patient-report instruments remain the most feasible and sustainable approaches for monitoring medication adherence in clinical settings. However, questions of their reliability and validity persist. Studies suggest that the 3-item instrument for retrospective adherence (IRA) developed by Wilson et al. offers a viable option for clinically monitoring medication adherence. Here we report the reliability and validity of the IRA among patients recruited from community-based HIV clinics and antiretroviral therapy (ART) dispensaries in a resource constrained township in Cape Town, South Africa.

METHODS

Women (n = 794) and men (n = 228) receiving ART completed the IRA at three time points: (a) in a face-to-face administration at enrollment (b) in1-week phone interview and (c) 1-month phone interview. Participants also provided contemporaneous blood samples for HIV viral load testing as a clinical outcome and unannounced phone-based pill counts as an objective assessment of ART adherence.

RESULTS

The IRA was internally consistent and showed evidence of time stability. The IRA also demonstrated validity with respect to pill count adherence, correlates of adherence, and HIV viral load. Response operating curve analysis yielded an area under the curve of 0.646, using 75% adherence as the cut-off, with 0.637 sensitivity and 0.567 specificity.

CONCLUSIONS

The IRA demonstrated reliability, construct validity and criterion validity in a resource constrained setting, supporting use of the IRA in research and clinical care.

Medical mistrust as a barrier to HIV prevention and care

Medical mistrust is fueled by conspiracy theories and histories of healthcare systems abuse and is a known determinant of health outcomes in minority populations. Plagued by multiple and pervasive conspiracy theories, HIV/AIDS has proven to be particularly hampered by medical mistrust. The current paper systematically reviews the literature on medical mistrust among people at risk for or living with HIV infection. The bulk of evidence from 17 studies supports medical mistrust as a barrier to HIV testing, engagement in prevention and care services, treatment uptake and adherence, and clinical outcomes. While findings mostly indicate that medical mistrust is a barrier to HIV prevention and care, some studies report null results and others suggest that medical mistrust may actually improve some HIV-related outcomes. Additionally, most of the reviewed literature was cross-sectional. Thus longitudinal, theory-driven research is needed to reconcile inconsistent findings and determine long term outcomes of medical mistrust. Interventions may then be developed to reduce the negative consequences associated with medical mistrust.

Phone-Delivered Intervention to Improve HIV Care for Young People Living With HIV: Trial to Inform Implementation and Utility

BACKGROUND

Phone-delivered counseling has demonstrated improved health outcomes for people living with HIV. However, counseling is hampered by a lack of guidance on the frequency and duration of intervention in relation to clinical benefits. The added benefits of bidirectional (ie, interactive) vs. unidirectional (ie, passive) text messages to augment counseling are also unknown. We conducted a clinical trial of adaptive phone counseling along with either bidirectional or unidirectional text messaging for people living with HIV.

METHODS

A community sample of 425 young people (aged 16-36 years) living with HIV in Georgia, USA, received weekly phone counseling sessions with the number of sessions determined by the participant and their counselor. Participants were subsequently randomized to either (1) weekly bidirectional text messages with their counselor or (2) weekly automated unidirectional text message reminders. Participants were followed for 16 months to assess 3 primary outcomes: antiretroviral therapy (ART) adherence, HIV care engagement, and HIV suppression.

RESULTS

Participants demonstrated improved clinical outcomes over the follow-up period, with 74% of those who were not taking ART initiating treatment, 65% of those on ART improving adherence, and 47% who had detectable viral loads at baseline attaining viral suppression. The number of sessions completed predicted improved ART adherence, greater care engagement, and HIV suppression over follow-ups. Bidirectional text messages impacted care engagement by moderating the effects of counseling sessions on HIV suppression.

CONCLUSIONS

Phone counseling augmented by bidirectional text messages has the potential to improve HIV care for young adults living with HIV.

Randomized Clinical Trial of Stigma Counseling and HIV Testing Access Interventions to Increase HIV Testing Among Black Sexual Minority Men and Transwomen

Advances in HIV prevention tools have outpaced our ability to ensure equitable access to these tools. Novel approaches to reducing known barriers to accessing HIV prevention, such as stigma and logistical-related factors, are urgently needed. To evaluate the efficacy of a randomized controlled trial with four intervention arms to address barriers to HIV/STI testing uptake (primary outcome) and PrEP use, depression, and HIV test results (secondary outcomes). We tested a 2 × 2 research design: main effect 1-stigma-focused vs. health information evaluation-focused counseling, main effect 2-offering HIV/STI testing appointments in person vs. at home with a counselor via video chat, and the interaction of the main effects. Participants (N = 474) residing in the southeastern USA were screened and enrolled in a longitudinal trial. Intervention efficacy was established using generalized linear modeling with binomial or Poisson distributions. Intervention efficacy demonstrated an increase in HIV/STI testing uptake when testing was made available at home with a counselor via video chat vs. in person (83% vs. 75% uptake, p < .05), and participants were also more likely to test positive for HIV over the course of the study in the at-home condition (14.5% vs. 9.4%, p < .05). Stigma-focused counseling resulted in lower depression scores and greater uptake of PrEP among participants < 30 years of age when compared with health information counseling (15.4% vs. 9.6%, p < .05). In order to prevent further disparities between HIV prevention advances and access to HIV prevention tools, we must prioritize improvements in linking people to care. Novel interventions, such as those proposed here, offer a practical, evidence-based path to addressing long-standing barriers to HIV prevention strategies. Trial registration: NCT03107910.

COVID-19 health information trust and prejudicial attitudes predict healthcare disruptions in the first year of COVID-19 among people living with HIV

Cross-sectional studies have reported that people living with HIV experienced disruptions to social relationships and healthcare during the first year of the COVID-19 pandemic. Furthermore, individuals with less trust in public health sources of COVID-19 information as well as those who held greater COVID-19 prejudicial attitudes experienced greater healthcare disruptions in the early months of COVID-19. To examine changes in trust and prejudicial attitudes in relation to healthcare disruptions during the first year of COVID-19, we followed a closed cohort of 115 men and 26 women ages 18 to 36 living with HIV over the first year of the COVID-19 pandemic. Findings confirmed that a majority of individuals continued to experience disruptions to their social relationships and healthcare over the course of the first year of COVID-19. In addition, trust in COVID-19 information from the CDC and state health department diminished over the year as did COVID-19 prejudicial attitudes. Regression models showed that lower trust in the CDC and health department and greater prejudicial attitudes toward COVID-19 early in the pandemic predicted greater healthcare disruptions over the year. In addition, greater trust in the CDC and health department early in COVID-19 predicted better antiretroviral therapy adherence later in the year. Results support an urgent need to regain and sustain trust in public health authorities among vulnerable populations.

Geometric approach to measuring intersectional stigma among black sexual minority men: reliability and validity in an HIV prevention context

BACKGROUND

Stigma and discrimination experiences attributable to multiple intersecting facets of the self (e.g. intersectional stigma) pose substantial challenges to accessing health services, including HIV prevention. While there have been theoretical advances in understanding multiple co-occurring stigmas, there are few psychometric instruments available to assess intersectional stigma. We have developed an approach to assessing intersectional stigma that conceptualises an intersection in geometric terms, defined as the line that connects points on two (or more) stigma dimensions and calculates scores derived from the geometric definition of intersecting lines.

METHODS

Following pilot studies to derive items and response formats, we administered newly developed enacted stigma (24-items) and anticipated stigma (17-items) scales with attributions to race and sexual minority status for stigma experiences to a sample of 422 Black sexual minority men at risk for HIV recruited through social media platforms.

RESULTS

The enacted and anticipated intersectional stigma scales, including subscales representing discrimination, interpersonal and felt stigma demonstrated evidence for reliability and construct validity. The enacted stigma scales were associated with medical mistrust, whereas the anticipated stigma scales predicted perceived barriers to using pre-exposure prophylaxis for HIV prevention.

CONCLUSIONS

The intersectional stigma scales offer greater specificity in measuring stigma experiences attributed to race, sexual minority status and the intersection of racial-sexual minority status.

Amphetamine use and its associations with antiretroviral adherence and viral load among sexual minority men and transgender women living with HIV

Substance use has complex associations to HIV disease progression. The current study tested the associations between several substances and HIV viral load while accounting for confounders relevant to HIV disease progression and substance use. Young sexual minority men and transgender women living with HIV (LWH) in Georgia (N = 385) completed measures and biological tests for HIV viral load and substance use. Multivariable regression models tested the role of specific drugs (i.e., alcohol, cannabis/THC, cocaine, and combined amphetamine and methamphetamine) directly on viral load and indirectly through antiretroviral (ART) adherence. ART adherence and HIV care self-efficacy were consistently associated with greater HIV suppression. Alcohol and cocaine were not associated with ART adherence or viral load. Cannabis was negatively associated with ART adherence (B = -.053, p = .037) but not viral load. Amphetamine/methamphetamine demonstrated significant direct effects on higher viral load (B = .708, p = .010) while indirectly influencing viral load through a negative association with ART adherence. Our findings support previous research demonstrating amphetamine/methamphetamine use impacts viral load both directly and indirectly through ART adherence. Interventions addressing amphetamine/methamphetamine use by young sexual minority men and transgender women LWH are urgently needed, and future research should focus on determining the mechanisms by which formulations of amphetamine impact HIV replication.Trial registration: ClinicalTrials.gov identifier: NCT03665532.

Novel Latent Profile Analysis of a Test of Concept, Stigma Intervention to Increase PrEP Uptake Among Black Sexual Minority Men

BACKGROUND

Pre-exposure prophylaxis (PrEP) has demonstrated efficacy for HIV prevention, yet uptake of PrEP among populations in urgent need of prevention tools (eg, Black sexual minority men) is limited, and stigma and medical mistrust remain strong barriers to accessing PrEP.

PURPOSE

To evaluate a test of concept brief intervention to address stigma and medical mistrust as barriers to PrEP uptake using novel latent profile analysis.

METHODS

Participants (N = 177) residing in the southeastern US were randomized to 1 of 4 arms to establish the potential impact of a brief, stigma focused counseling intervention (referred to as Jumpstart ) to increase PrEP uptake. We estimated intervention effect size (Cramer's V) for PrEP uptake and then explored differential intervention effects across latent profiles of psychosocial barriers to PrEP use.

RESULTS

The intervention resulted in small, but meaningful effect size, with self-reported PrEP uptake increasing across Jumpstart conditions with the control condition reporting 24% uptake and Jumpstart plus text/phone calls (the most intensive intervention arm) reporting 37% uptake, and a similar pattern emerging for biologically confirmed PrEP use. Among participants 30 and older, Jumpstart participants were more likely to move to a postintervention profile with fewer barriers than control participants and reported the highest uptake of PrEP.

CONCLUSIONS

Addressing social/emotional barriers to PrEP uptake is an essential component of bridging the gap between advances being made in biomedical forms of HIV prevention, and establishing and supporting access to those advances.

The emergence and persistence of the anti-vaccination movement

Vaccine hesitancy is a significant threat to public health and the anti-vaccination movement has played a significant role in communicable disease outbreaks. This commentary discusses the history and tactics of vaccine denialists and anti-vaccination groups. Anti-vaccination rhetoric is robust on social media platforms, and vaccine hesitancy has proven to impede the uptake of both established and new vaccines. Effective counter-messaging is needed to preemptively discredit vaccine denialists and reduce their influence on vaccine uptake. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Rejection-identification and increased use of geosocial networking apps to meet male sexual partners among Black men who have sex with men

Objective: The use of geosocial networking (GSN) apps to meet male sexual partners may contribute to HIV infection risk for Black men who have sex with men (MSM), but the psychosocial underpinnings of this behavior are not understood. In social psychology, the Rejection-Identification Model posits that identification with a socially stigmatized group emerges as a means of coping in response to perceived stigmatization-which can shape behavior. This study tested the Rejection-Identification process as a facilitator of increased use of GSN apps to meet male sexual partners among Black MSM who use these apps. Method: Black MSM (N = 103; M_age = 29.8) reporting a male sexual partner from a GSN app in the past year were recruited nationally from Grindr and Facebook. Participants completed an online survey in which they reported sociodemographic information, measures of racial stigma and Black identity, and characteristics of their past-year male sexual partners. Results: Participants in this sample reported that most of their past-year male partners came from GSN apps (M_percent = 82.3), and results from hypothesis testing showed that greater perceived devaluation of Black people in society (i.e., public racial stigma) was associated with an increased percentage of GSN-met partners. In line with the Rejection-Identification Model, this relationship was mediated by greater Black identity centrality. Conclusions: Findings highlight psychosocial correlates of increased GSN app use to meet male sexual partners among Black MSM, which may place Black MSM at increased risk for HIV infection. Results also point to the possibility that these factors may be harnessed to develop HIV prevention strategies for Black MSM. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Prepandemic Predictors of Medication Adherence and HIV Viral Load During the First Year of COVID-19

ABSTRACT

Studies have reported significant immediate impacts of the COVID-19 pandemic on the social relationships and health care of people living with HIV. This study followed a closed cohort of young people living with HIV over the first year of the COVID-19 pandemic. Participants were men and women (N = 140) age 36 years and younger who were living with HIV and had demonstrated suboptimal adherence to antiretroviral therapy, unsuppressed HIV viral load, or active substance use in a run-in study. The results confirmed that participants continued to experience significant disruptions to their social relationships and health care over the course of the first year of the COVID-19 pandemic. There was evidence for sustained impacts on transportation, housing stability, and food security during the first year of COVID-19. Multivariable models showed that greater pre-COVID-19 social support predicted greater antiretroviral therapy adherence and greater HIV suppression (lower viral load) over the first year of the COVID-19 pandemic. Efforts to plan and prepare people living with HIV for future social crises, including future pandemics, should emphasize building and sustaining social support.

Lifetime prevalence of syphilis infection among predominantly Black sexual and gender minorities living with HIV in Atlanta, Georgia: a cross-sectional analysis

OBJECTIVES

Syphilis infection disproportionately impacts Black sexual and gender minorities (SGM) in the United States. The extent of this impact among those living with HIV has been minimally examined. This study sought to examine lifetime syphilis prevalence and associated factors in a community sample of predominantly Black SGM living with HIV in the Southeastern US.

DESIGN

Participants (N = 174) enrolled in a stigma-mitigation trial for people living with HIV in Atlanta, Georgia, completed a sub-study involving testing for Treponema pallidum antibodies, indicative of lifetime syphilis infection. We performed chi-square and Fisher's exact tests to assess sociodemographic and healthcare differences by presence/absence of lifetime syphilis infection.

RESULTS

Most participants identified as non-Hispanic Black (n = 142/174; 81.6%) and cisgender male (n = 146/174; 83.9%). More than two thirds (n = 120/174) identified as gay/homosexual. We documented a 55.7% (n = 97/174) lifetime prevalence of syphilis infection and observed differences by sexual identity, with 77.3% (n = 75/97) of those screening positive reporting gay/homosexual identity relative to 58.4% (n = 45/77) of those screening negative (chi-square[1] = 7.8, p < 0.010).

CONCLUSION

Findings underscore how syphilis prevention efforts have missed the most marginalized, warranting a renewed, comprehensive strategy for improving the sexual health of Black SGM. Embedding targeted, respectful community engagement, expanded testing access, and healthcare provider training into broader sexual health and psychosocial wellness efforts is needed.

Perceived sensitivity to medicines and medication concerns beliefs predict intentional nonadherence to antiretroviral therapy among young people living with HIV

Objective: Among the sources of antiretroviral therapy (ART) nonadherence are patient decisions to skip or stop taking their medications, often stemming from medication beliefs and concerns about side- effects. While individuals who perceive greater sensitivity to medicines may be prone to medication concerns, understanding how these factors contribute to HIV treatment adherence requires further research. The current study tested the direct and indirect effects of perceived sensitivity to medicines on intentional nonadherence to ART, and whether medication concerns mediate this association.Methods: A sample of 418 younger (< 36 years of age) people living with HIV was recruited through community outreach to complete assessments of perceived sensitivity to medicines, medication concerns beliefs, adherence assessed by unannounced phone- based pill counts and HIV viral load, as well as monthly follow- up assessments of intentional nonadherence over a 15- month period.Results: Analyses at baseline and prospective Poisson regression models conducted over 15- months converged to show that perceived sensitivity to medicines significantly predicted intentional nonadherence to ART through medication concerns.Conclusions: These findings suggest that people who perceive greater sensitivity to medicines are prone to greater medication concerns that are related to intentional nonadherence. Cognitive behavioral interventions are needed to resolve medication concerns and reduce intentional nonadherence among people receiving ART.

Intersecting alcohol use and depression impedes HIV treatment in the rural South, USA

This study tested the hypothesis that the co-occurrence of alcohol use and depressive symptoms predicts HIV suppression and antiretroviral therapy (ART) adherence among people living with HIV. Baseline cross-sectional results showed a significant interaction between depressive symptoms and alcohol use in predicting HIV suppression; individuals who drank more alcohol and had higher depressive symptoms demonstrated poorer HIV suppression relative to those who had fewer depressive symptoms. In a one-year longitudinal analysis of ART adherence, alcohol use and depressive symptoms measured in daily text-message assessments demonstrated that neither alcohol use nor depressive symptoms alone predicted ART adherence. However, the intersection of alcohol use on days when experiencing depressive symptoms did significantly predict ART non-adherence, for both moderate and heavy alcohol drinkers. Findings suggest that the co-occurrence of alcohol use and depressive symptoms is a robust predictor of poor HIV treatment outcomes.

Precarious manhood and intentions to initiate preexposure prophylaxis among Black sexual minority men

OBJECTIVE

The use of preexposure prophylaxis (PrEP) to prevent HIV infection is significantly low among Black sexual minority men (BSMM), although this group experiences the greatest HIV burden in the United States. One contextual factor suggested to impact BSMM's HIV prevention efforts is the concern about, and adherence to, cultural conceptions and expectations of masculinity. The present study sought to better understand the association between masculinity and PrEP uptake by examining associations between gender-relevant beliefs and perceptions, and intentions to initiate PrEP among a sample of BSMM residing in the U.S. South.

METHOD

Participants (N = 114) completed assessments of precarious manhood beliefs, attitudes toward PrEP, concerns about PrEP use impacting support from social networks, projected perceptions of masculinity, and intentions to initiate PrEP.

RESULTS

Precarious manhood beliefs were associated with greater intention to initiate PrEP; however, the indirect path of this association through attitudes toward PrEP was associated with lower intentions to initiate PrEP. In a hierarchical regression model, projected perceptions of masculinity were associated with intentions to initiate PrEP over and above other factors considered. Specifically, believing that one will be perceived as less masculine for seeking PrEP was associated with lower intentions to initiate PrEP.

CONCLUSIONS

Findings suggest that BSMM's construal of masculinity in relation to HIV and PrEP is associated with intentions to initiate PrEP. Implications for increasing PrEP uptake among BSMM are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Believing That It Is Hazardous to Mix Alcohol With Medicines Predicts Intentional Nonadherence to Antiretrovirals

BACKGROUND

Drinking alcohol is a robust predictor of medication nonadherence. In addition to the impact of intoxication on adherence, individuals who believe that it is hazardous to mix medications with alcohol (ie, interactive toxicity beliefs) may forgo taking their medications when drinking. Previous research suggests that alcohol-related intentional nonadherence is a direct result of interactive toxicity beliefs. This study prospectively tested the association between alcohol interactive toxicity beliefs and intentional nonadherence to HIV treatment [ie, antiretroviral therapy (ART)].

METHODS

Four hundred eight people living with HIV completed comprehensive baseline assessments and 15-month attributions for ART nonadherence.

RESULTS

One in 5 participants reported foregoing taking their ART when drinking out of concern for hazardous mixing of alcohol and ART. Poisson regression models predicting the number of months that participants were intentionally nonadherent to ART because they were drinking was predicted by alcohol-ART interactive toxicity beliefs.

CONCLUSIONS

Beliefs that it is hazardous to drink alcohol when taking medications explains intentional nonadherence and should be directly addressed in adherence improvement interventions for people living with HIV who drink alcohol.

Prevalence and correlates of depressive symptoms, and points of intervention, in rural central Uganda: results from a cross-sectional population-based survey of women and men

OBJECTIVES

The present study aimed to identify the prevalence and correlates of depressive symptoms and potential intervention points among women and men from a population-based sample in rural central Uganda.

DESIGN

A cross-sectional study.

SETTING

Four districts in rural Uganda.

PARTICIPANTS

Women and men aged 15-59 residing in four districts in rural Uganda accepting home-based HIV testing who completed a baseline survey at the time of testing.

PRIMARY OUTCOME MEASURES

Depressive symptoms measured by the 10-item Center for Epidemiological Studies Depression Scale using a cut-off score of 13 for significant depressive symptoms.

RESULTS

Among a sample of 9609 women and 6059 men, 1415 (14.7%) women and 727 (12.0%) men met criteria for significant depressive symptoms. Having ever received mental health services was associated with lower odds of significant depressive symptoms (women: adjusted OR (adjOR)=0.32, 95% CI=0.22 to 0.47; men: adjOR=0.36, 95% CI=0.18 to 0.62). Having received outpatient (women: adjOR=3.64, 95% CI=3.14 to 4.22; men: adjOR=3.37, 95% CI=2.78 to 4.07) or inpatient (women: adjOR=5.44, 95% CI=4.24 to 6.97; men: adjOR=3.42, 95% CI=2.21 to 5.28) care in the prior 6 months was associated with greater odds of significant depressive symptoms. For women only, known HIV positive status (adjOR=1.37, 95% CI=1.05 to 1.77), and for men only, alcohol misuse (adjOR=1.38, 95% CI=1.12 to 1.70), were associated with increased odds of significant depressive symptoms.

CONCLUSION

Our findings suggest that depression screening within outpatient and inpatient settings may help to identify people in need of mental health services. Routine screening in outpatient or inpatient clinics along with the implementation of evidence-based interventions could ultimately help close the mental health gap for depression in this and similar settings.

Medication adherence in young adults with youth-onset type 2 diabetes: iCount, an observational study

AIMS

To assess prevalence of, and factors associated with, medication adherence of young adults with youth-onset type 2 diabetes.

METHODS

Oral hypoglycaemia agent (OHA) adherence was measured with unannounced telephone pill counts, insulin adherence was self-reported. Those taking ≥ 80% of pills/insulin were classified "high-adherent," <80% of pills/insulin "low-adherent." Analyses included unadjusted, and adjusted linear and logistic regressions assessing associations of participant factors with adherence.

RESULTS

For people taking OHAs (N = 212, mean age 26 yrs, 67% women, 18% non-Hispanic White, 35% non-Hispanic Black, 41% Hispanic), 69.8% were low-adherent. HbA1c was lower in the high-adherent group (9.2%/77 mmol/mol vs. 10.0%/86 mmol/mol, p < 0.04). More non-Hispanic Blacks were low-adherent (85.7%) than Hispanics (60.2%) and non-Hispanic whites (55.3%, p < 0.002); 91.4% of participants without healthcare coverage were low-adherent vs. 65.5% of those with coverage (p < 0.004). After adjustment, gender (p = 0.024), race/ethnicity (p < 0.001) and healthcare coverage (p = 0.001) remained related to OHA adherence. For insulin (N = 192), 37% were low-adherent. HbA1c was associated with insulin adherence (low = 11.2%/99 mmol/mol vs. high = 10.0%/86 mmol/mol, p < 0.001) with and without adjustment.

CONCLUSIONS

Young adults with youth-onset type 2 diabetes, especially females, non-Hispanic Blacks and those without healthcare coverage, commonly had low-OHA adherence. Glycaemic control was also poor. Interventions to improve medication adherence are needed for this vulnerable group.

Finding the Right Angle: A Geometric Approach to Measuring Intersectional HIV Stigma

Intersectionality has emerged as theoretically and practically important to advancing HIV stigma research. However, few psychometric measures capture the intricacies of intersectional stigma. Grounded in the HIV stigma framework and contemporary theories of intersectionality, this paper describes a novel approach to conceptualizing the measurement of intersectional stigma. Taking the notion of an intersection literally, that is the point at which two or more lines meet and form a union, we offer a geometric conceptualization for developing a psychometric instrument to measure intersectional stigma. Ratings of stigmatized attributes, such as stigma ascribed to gender, race, sexual orientation, and HIV status are assessed on independent scales to calculate their intersection using the Pythagorean Theorem, c = [Formula: see text] (a² + b²) and its extension to multiple stigmatized attributes d = [Formula: see text] (a² + b² + c²). Data from a sample of Black /African American women living with HIV were used to test the concept of a geometric approach to measuring intersectional enacted stigma and intersectional anticipated stigma. Findings from the test of concept were encouraging and warrant further scale development research.

Substance Use-Related Intentional Nonadherence to Antiretroviral Therapy Among Young Adults Living with HIV

Antiretroviral therapy (ART) reduces HIV disease burden, increases life expectancy, and prevents HIV transmission. Previous research suggests that believing that it is harmful to take ART when using substances (i.e., interactive toxicity beliefs) leads to intentional ART nonadherence; however, these associations have not been investigated among younger adults living with HIV and have not been linked to clinical outcomes. We examined the associations among interactive toxicity beliefs, intentional nonadherence, and HIV clinical outcomes in young adults living with HIV. People living with HIV younger than the age of 36 years who tested positive for at least one substance use biomarker (N = 406) completed a 1-month pretrial run-in study that included computerized interviews, substance use biomarkers, HIV viral load, and unannounced pill counts for ART adherence. Analyses compared three HIV clinical outcome groups: (1) HIV viral unsuppressed, (2) HIV viral suppressed and ART nonadherent, and (3) HIV viral suppressed and ART adherent, on substance use, interactive toxicity beliefs, and substance use-related intentional ART nonadherence. Results showed that a majority of participants reported intentional nonadherence. Participants with unsuppressed HIV reported greater interactive toxicity beliefs and intentional nonadherence. We conclude that intentional nonadherence adds to the detrimental impacts of substance use on ART adherence and interactive toxicity beliefs that foster these behaviors may be amenable to interventions.

Examining Stigmatizing Beliefs about PrEP Use among Black Sexual Minority Men: A Test of Explanatory Mechanisms

Stigma often is cited as a barrier to the uptake and use of pre-exposure prophylaxis (PrEP) to prevent HIV among Black sexual minority men (SMM). Socialized gender norms (i.e., restrictive emotionality) are associated with experiences and manifestations of stigma in men. However, the association between restrictive emotionality and the stigma surrounding PrEP use has received little attention in previous research. The present study examines the association between restrictive emotionality and holding stigmatizing beliefs about PrEP use with a theoretically informed serial mediation model testing internalized homophobia and LGBT community connectedness as mediators among a sample of 455 Black SMM in the Southeastern US. Results indicate that restrictive emotionality is associated with stigmatizing beliefs about PrEP use. Further, internalized homophobia and LGBT community connectedness were found to partially mediate the proposed relationship serially. Internalized homophobia, but not LGBT community connectedness, also independently mediated the association between restrictive emotionality and stigmatizing beliefs of PrEP use. This study provides important insights into how aspects of masculinity influence the manifestation of stigmatizing beliefs about PrEP use among Black SMM. The present findings have implications for reducing these beliefs, which are known to negatively impact uptake and use of the HIV prevention tool among Black SMM at elevated risk for HIV.

Alcohol-Antiretroviral Therapy Interactive Toxicity Beliefs and Intentional Medication Nonadherence: Review of Research with Implications for Interventions

The successful treatment of HIV infection relies on adherence to antiretroviral therapy (ART). Alcohol use remains a threat to ART adherence, including the beliefs held by people who drink alcohol that it is harmful to take ART when consuming alcohol (i.e., alcohol-ART interactive toxicity beliefs, AA-ITB). We reviewed the current research that has investigated AA-ITB and their relationship to intentional ART nonadherence. The review of 17 published studies found that AA-ITB are prevalent among people receiving ART and that AA-ITB are directly associated with ART nonadherence and incomplete HIV suppression. Family, friends and healthcare providers are common sources and reinforcers of AA-ITB. Studies suggest that AA-ITB may best be explained by the Medication Necessity and Concerns Beliefs Model, treating AA-ITB as a specific circumstance of medication concerns. Interventions are needed to communicate the realities of potential medication interactions and dispel myths that it is harmful to mix alcohol with ART, while not inadvertently suggesting that it is safe to drink with all medications, which could undermine adherence to ART by increasing alcohol use.

Undetected anogenital sexually transmitted infections among young adults living with HIV and receiving antiretroviral therapy: Implications for HIV treatment as prevention

Undetected sexually transmitted infections (STIs) pose health threats to people living with HIV and when combined with uncontrolled HIV can amplify HIV transmission. The current study screened 174 self-identified men under age 36 living with HIV and receiving antiretroviral therapy (ART) for urethral and rectal incident chlamydia and gonorrhea infections. Participants were also screened for biomarkers indicating alcohol and other drug use, subclinical genital inflammation, and HIV viral load. ART adherence and sexual behaviors were also assessed prospectively over 1 month. Results detected an undiagnosed STI in 32 (18%) individuals. Participants with a previously undetected STI had significantly greater HIV viremia than those who did not have an STI after controlling for several confounding variables. Participants with an undetected STI also engaged in greater condomless anal intercourse with HIV negative and unknown status partners, including partners to whom they had not disclosed their HIV status. These findings show that undetected STI are associated with incomplete ART adherence and unsuppressed HIV, all of which are important for preventing HIV transmission.

Undisclosed HIV Status to Sex Partners and Its Unintended Consequences in the Era of Undetectable = Untransmittable

BACKGROUND

Adherence to antiretroviral therapy (ART) and sustained HIV suppression virtually eliminate HIV transmission, eg, having an undetectable viral load renders HIV untransmittable (U=U). Owing to the greatly reduced likelihood of HIV transmission when viral load is undetectable, we studied one behavioral ramification of adopting a U=U prevention strategy-not disclosing HIV status to sex partners.

SETTING

Cisgender men recruited through community outreach in the state of Georgia, USA.

METHODS

We examined HIV status disclosure to sex partners among 345 young (median age = 29 years) men receiving ART. Data were collected using computerized interviews, daily sexual behavior surveys over 28 days, unannounced pill counts for ART adherence, urine tests for drug use and urogenital health, and blood samples for HIV viral load.

RESULTS

One in 3 participants (34%) engaged in condomless anal/vaginal intercourse with an HIV-negative/unknown HIV status partner over 28 days. Average ART adherence was 76%, and one in 5 men had detectable HIV viral loads. Men who engaged in condomless sex with undisclosed partners demonstrated significantly less HIV disclosure to family and friends and had fewer enacted stigma experiences. Hierarchical regression models showed that endorsing U=U as a personal HIV prevention strategy predicted undisclosed condomless sex over and above substance use, HIV stigma experiences, disclosure to family and friends, ART adherence, and HIV viral load.

CONCLUSIONS

Interventions are needed to improve ART adherence and assist men living with HIV in their decisions to disclose HIV status to sex partners.

Randomized Community Trial Comparing Telephone versus Clinic-Based Behavioral Health Counseling for People Living with HIV in a Rural Setting

PURPOSE

To test the efficacy of a theory-based behavioral intervention delivered via telephone versus clinic-based counseling to improve HIV outcomes and reduce alcohol consumption for people at-risk for treatment failure in a rural setting.

METHODS

Patients receiving HIV care (N = 240) were randomized using a computer-generated scheme to one of three conditions: (a) telephone behavioral health counseling, (b) clinic-based behavioral health counseling, or (c) attention control nutrition education. Behavioral counseling was delivered by either a community nurse or a paraprofessional patient navigator, with differences examined. Participants were followed for 12 months to assess medication adherence using unannounced pill counts and alcohol use measured by electronic daily text message assessments, and 18 months for HIV viral load and retention in care extracted from medical records.

FINDINGS

There was evidence for telephone and office-based counseling demonstrating greater medication adherence than the control condition but only in the short term. Clinic-based behavioral counseling significantly reduced alcohol use to a greater degree than telephone counseling and the control condition. There were no other differences between conditions. There were also no discernable differences between counseling delivered by the community nurse and the patient navigator.

CONCLUSIONS

Telephone and clinic-based counseling demonstrated improved medication adherence in the short term, while clinic-based counseling demonstrated reductions in alcohol use. The modest outcomes suggest that intensive intervention strategies are needed for patients that clinicians identify as at-risk for treatment discontinuation and treatment failure.

Prejudicial beliefs and COVID-19 disruptions among sexual minority men living with and not living with HIV in a high SARS-CoV-2 prevalence area

The COVID-19 pandemic has had profound health and social impacts. COVID-19 also affords opportunities to study the emergence of prejudice as a factor in taking protective actions. This study investigated the association of COVID-19 concerns, prejudicial beliefs, and personal actions that involve life disruptions among people not living with and people living with HIV. 338 Black/African American men not living with HIV who reported male sex partners and 148 Black/African American men living with HIV who reported male sex partners completed a confidential survey that measured COVID-19 concern, COVID-19 prejudice, and personal action and institutionally imposed COVID-19 disruptions. Participants reported having experienced multiple social and healthcare disruptions stemming from COVID-19, including reductions in social contacts, canceling medical appointments, and inability to access medications. Mediation analyses demonstrated that COVID-19 concerns and COVID-19 prejudice were associated with personal action disruptions, indicating that these social processes are important for understanding how individuals modified their lives in response to COVID-19. It is imperative that public health efforts combat COVID-19 prejudice as these beliefs undermine investments in developing healthcare infrastructure to address COVID-19 prevention.

Comparative effects of telephone versus in-office behavioral counseling to improve HIV treatment outcomes among people living with HIV in a rural setting

With the expansion of telehealth services, there is a need for evidence-based treatment adherence interventions that can be delivered remotely to people living with HIV. Evidence-based behavioral health counseling can be delivered via telephone, as well as in-office services. However, there is limited research on counseling delivery formats and their differential outcomes. The purpose of this study was to conduct a head-to-head comparison of behavioral self-regulation counseling delivered by telephone versus behavioral self-regulation counseling delivered by in-office sessions to improve HIV treatment outcomes. Patients (N = 251) deemed at risk for discontinuing care and treatment failure living in a rural area of the southeastern USA were referred by their care provider. The trial implemented a Wennberg Randomized Preferential Design to rigorously test: (a) patient preference and (b) comparative effects on patient retention in care and treatment adherence. There was a clear patient preference for telephone-delivered counseling (69%) over in-office-delivered counseling (31%) and participants who received telephone counseling completed a greater number of sessions. There were few differences between the two intervention delivery formats on clinical appointment attendance, antiretroviral adherence, and HIV viral load. Overall improvements in health outcomes were not observed across delivery formats. Telephone-delivered counseling did show somewhat greater benefit for improving depression symptoms, whereas in-office services demonstrated greater benefits for reducing alcohol use. These results encourage offering most patients the choice of telephone and in-office behavioral health counseling and suggest that more intensive interventions may be needed to improve clinical outcomes for people living with HIV who may be at risk for discontinuing care or experiencing HIV treatment failure.

Perceived sensitivity to medicines and the experience of side-effects: understanding intentional medication nonadherence among people living with HIV

Patient initiated decisions to forgo taking medications (i.e. intentional nonadherence) pose significant challenges to managing chronic health conditions. Identifying factors and their underlying mechanisms that impede medication adherence is essential to designing treatment improvement interventions. This study tested a conceptual model that posits the effects of perceived sensitivity to medicines on adherence can be explained by the experience of side-effects, leading to intentionally nonadherent behaviors. Patients receiving HIV care in the southern United States (N = 209) completed measures of perceived sensitivity to medicines, antiretroviral therapy (ART) side-effects, intentional nonadherence and overall adherence. Patients also provided consent to access their electronic medical records to collect subsequent reports of HIV viral load tests. Results indicated that more than one in four participants were intentionally nonadherent to ART. Mediation modeling showed that perceived sensitivity to medicines was associated with greater experience of ART side-effects and intentional nonadherence, which impacted overall ART adherence and HIV viral load. There were also significant indirect effects of perceived sensitivity to medicines on HIV viral load through side-effects and intentional nonadherence. Patients with increased perceived sensitivity to medicines are at risk for poor treatment outcomes and these negative outcomes are partly explained by experiencing greater side-effects and intentional nonadherence.

Trust in health information sources and its associations with COVID-19 disruptions to social relationships and health services among people living with HIV

BACKGROUND

SARS-CoV-2 infection (COVID-19) is potentially severe for individuals with compromised immune systems, including people living with HIV. Along with the direct health threats of COVID-19, there are disruptions to social relationships and health services resulting from mitigation efforts instituted by public health authorities. This study examined the relationship between trust in the government and trust in COVID-19 health information from the US CDC, state health departments, and social media on the experience of COVID-19 social and health services-related disruptions.

METHODS

People living with HIV (N = 459) recruited through social media advertisements and chain referrals completed confidential surveys delivered through an online platform.

RESULTS

Participants experienced high-levels of disruptions to social relationships and health services attributable to COVID-19 mitigation efforts. We also observed high-rates of inaccurate information and low-levels of trust in government and sources of COVID-19 information. Greater disruptions to social relationships were predicted by more concern about oneself and others contracting COVID-19, whereas disruptions to health services were predicted by greater concern for oneself contracting COVID-19, greater general medical mistrust, and less trust in information from the CDC.

CONCLUSIONS

Findings have implications for the necessity of rebuilding public trust in credible sources of health information and stepping up efforts to counter sources of inaccurate information.

Faster than warp speed: early attention to COVD-19 by anti-vaccine groups on Facebook

Background

The unprecedented rapid development of COVID-19 vaccines has faced SARS-CoV- (COVID-19) vaccine hesitancy, which is partially fueled by the misinformation and conspiracy theories propagated by anti-vaccine groups on social media. Research is needed to better understand the early COVID-19 anti-vaccine activities on social media.

Methods

This study chronicles the social media posts concerning COVID-19 and COVID-19 vaccines by leading anti-vaccine groups (Dr Tenpenny on Vaccines, the National Vaccine Information Center [NVIC] the Vaccination Information Network [VINE]) and Vaccine Machine in the early months of the COVID-19 pandemic (February–May 2020).

Results

Analysis of 2060 Facebook posts showed that anti-vaccine groups were discussing COVID-19 in the first week of February 2020 and were specifically discussing COVID-19 vaccines by mid-February 2020. COVID-19 posts by NVIC were more widely disseminated and showed greater influence than non-COVID-19 posts. Early COVID-19 posts concerned mistrust of vaccine safety and conspiracy theories.

Conclusion

Major anti-vaccine groups were sowing seeds of doubt on Facebook weeks before the US government launched its vaccine development program ‘Operation Warp Speed’. Early anti-vaccine misinformation campaigns outpaced public health messaging and hampered the rollout of COVID-19 vaccines.

Drug Use and Life Chaos as Potential Factors Contributing to HIV Viral Load among People with Lower Health Literacy

Lower health literacy is associated with poorer health outcomes in people living with HIV (PLWH), but the explanatory mechanisms for these associations are not well understood. Factors such as drug use and life chaos may at least in part account for the relationship between lower health literacy and poor health outcomes. The current study tested the hypothesis that lower health literacy would predict drug use, which in turn would predict life chaos, and that all three factors would be related to poorer heath, defined by higher concentrations of HIV viremia. Methods: Patients receiving HIV care (N = 251) at an HIV clinic in the southeastern United States completed computerized interviews and permission to access their medical records. Process modeling tested direct and indirect effects of all variables in a serial mediation model. Results: The direct effects of lower health literacy and drug use were significantly related to HIV viremia. In addition, the indirect effect of health literacy on HIV viremia through drug use was significant. However, results did not demonstrate any effect, direct or indirect, of life chaos on HIV viremia. Conclusion: Findings from this study bolster previous research demonstrating lower health literacy and drug use as barriers to HIV care, and show that lower health literacy impacts HIV viremia, at least in part, through drug use. Interventions aimed to improve HIV treatment outcomes in lower health literacy populations may be enhanced by integrating evidence-based approaches to reducing drug use.

Cumulative Effects of Stigma Experiences on Retention in HIV Care Among Men and Women in the Rural Southeastern United States

The stigmatization of HIV infection impedes every step along the HIV continuum of care, particularly care engagement and retention. The differential effects of various sources of stigma on retention in HIV care have been the subject of limited research. We examined the accumulation of HIV stigma experiences over 1 year in relationship to treatment retention among 251 men and women marginally engaged in HIV care in the southeastern United States. Results showed that cumulative stigma experiences predicted poorer retention in care, with greater stigma experiences related to less consistency in attending scheduled medical appointments. HIV stigma originating from family members and acts of overt discrimination were the most frequently experienced sources of stigma and were most closely associated with disengagement from HIV care. In addition, analyses by gender indicated that retention in care for men was impacted by stigma to a greater extent than among women. These findings reaffirm the importance of HIV stigma as a barrier to HIV care and provide new directions for interventions to mitigate the negative effects of stigma on patients who are not fully engaged in HIV care.

COVID-19 conspiracy beliefs, health behaviors, and policy support

Conspiracy theories have been proliferating during the COVID-19 pandemic. Evidence suggests that belief in conspiracy theories undermines engagement in pro-health behaviors and support for public health policies. Moreover, previous work suggests that inoculating messages from opinion leaders that expose conspiracy theories as false before people are exposed to them can help to prevent belief in new conspiracies. Goals of this study were to: (a) explore associations between COVID-19 conspiracy beliefs with SARS-CoV-2 vaccine intentions, cooperation with public health recommendations, and support for public health policies among U.S. adults and (b) investigate trusted sources of COVID-19 information to inform strategies to address conspiracy beliefs. A cross-sectional, online survey was conducted with 845 U.S. adults in April 2020. Data were analyzed using analyses of variance and multivariable regressions. One-third (33%) of participants believed one or more conspiracies about COVID-19. Participants who believed conspiracies reported that their intentions to vaccinate were 3.9 times lower and indicated less support for COVID-19 public health policies than participants who disbelieved conspiracies. There were no differences in cooperation with public health recommendations by conspiracy belief endorsement in the multivariable regression analysis. Although there were some key differences in trusted sources of COVID-19 information, doctor(s) were the most trusted source of information about COVID-19 overall with 90% of participants trusting doctor(s). Doctor(s) may play a role in addressing COVID-19 conspiracy theories before people are exposed to them to promote COVID-19 prevention efforts.

Substance Use, HIV Serostatus Disclosure, and Sexual Risk Behavior in People Living with HIV: An Event-Level Analysis

People living with HIV (PLWH) face difficult decisions about disclosing their HIV status to new sexual partners. Alcohol and other drug use could impact these decision-making processes and subsequent sexual risk behavior. We sought to examine the event-level relationships between substance use, HIV disclosure, and condom use in PLWH and their first-time HIV-negative or unknown status sexual partners. Adult PLWH were recruited from care settings in a southeastern U.S. city. Participants reported their sexual behavior for 28 consecutive days via text message prompts. We employed multilevel covariation in a causal system to examine the event-level relations between substance use and condom use. We proposed that this relationship would be mediated by HIV disclosure and moderated by viral suppression status. A total of 243 participants (83% male, 93% Black) reported 509 sexual events with first-time HIV-negative/unknown status sexual partners. Substance use at the time of sex was negatively associated with disclosure in PLWH with suppressed viral load (OR 0.29, β = - 1.22, 95% CI [- 2.42, - 0.03], p = .045), but differentially associated with condom use in PLWH with detectable versus undetectable viral load. In PLWH with viral suppression, participants who always disclosed versus who never disclosed their HIV status were more likely to use condoms (β = 1.84, 95% CI [0.35, 3.53], p = .017), but inconsistent disclosers were less likely to use a condom after disclosing (OR 0.22, 95% CI [0.07, 0.68], p = .008). Event-level analysis offers a more nuanced understanding of the proximal (substance use, HIV disclosure) and person-level (substance use, viral load) determinants of HIV transmission risk behavior in PLWH.

Masculine ideology and Black men who have sex with men's interest in HIV pre-exposure prophylaxis (PrEP)

We examined how traditional masculinity and stigma surrounding HIV pre-exposure prophylaxis (PrEP) affect PrEP interest among Black men who have sex with men (BMSM). One hundred twenty-three men attending a Black Gay Pride event completed measures assessing traditional masculinity, PrEP stigma, and PrEP interest along with two behavioral measures of interest in PrEP. Results demonstrated that avoidance of femininity directly related to interest in PrEP and indirectly through conformity to heterosexual self-presentation. Further, PrEP stigma differentially moderated both of these relationships. Interventions designed to improve engagement of PrEP for BMSM should be attentive to traditional masculinity as a barrier.

Effects of enhanced STI partner notification counselling and provider-assisted partner services on partner referral and the incidence of STI diagnosis in Cape Town, South Africa: randomised controlled trial

Objectives

We investigated the effects of an enhanced partner notification (PN) counselling intervention with the offer of provider-assisted referral among people diagnosed with STI in a Cape Town public clinic.

Methods

Participants were adults diagnosed with STI at a community clinic. After the standard STI consultation, participants were randomly allocated in a 1:1:1 ratio to (1) ‘HE’: 20 min health education; (2) ‘RR’: 45 min risk reduction skills counselling; or (3) ‘ePN’: 45 min enhanced partner notification communication skills counselling and the offer of provider-assisted referral. The primary outcome was the incidence of repeat STI diagnoses during the 12 months after recruitment, and the secondary outcome was participants’ reports 2 weeks after diagnosis of notifying recent partners. Incidence rate ratios (IRRs) were used to compare the incidence rates between arms using a Poisson regression model.

Results

The sample included 1050 participants, 350 per group, diagnosed with STI between June 2014 and August 2017. We reviewed 1048 (99%) participant records, and identified 136 repeat STI diagnoses in the ePN arm, 138 in the RR arm and 141 in the HE arm. There was no difference in the annual incidence of STI diagnosis between the ePN and HE arms (IRR: 1.0; 95% CI 0.7 to 1.3), or between the RR and HE arms (IRR: 0.9; 95% CI 0.7 to 1.2). There was a greater chance of a partner being notified in the ePN condition compared with the HE condition, 64.3% compared with 53.8%, but no difference between the RR and HE arms.

Conclusions

PN counselling and education with provider-assisted services has the potential to change the behaviour of people diagnosed with STIs, increasing the number of partners they notify by more than 10%. However, these changes in behaviour did not lead to a reduction of repeat STI diagnoses.

HIV Stigma, Depressive Symptoms, and Substance Use

Substance use problems undermine HIV treatment and secondary prevention efforts. Research is needed to better understand predictors of substance use among people living with HIV (PLWH). We examined whether internalized stigma and enacted HIV stigma are associated with three indicators of substance use among PLWH, including numbers of (1) substances used, (2) substances used at moderate to high risk, and (3) times substances were used before sex, through the mediator of depressive symptoms. Participants included 358 PLWH aged 18-35 years from Georgia, United States. At baseline, participants completed measures of internalized and enacted stigma, depressive symptoms, and substance use severity. Substance use was additionally tested with urinalysis. Following baseline, participants reported their use of substances before sex for 28 days through daily text messaging. Data were analyzed using path analysis in R. On average, participants tested positive for 1.24 (range: 0-6) substances used, reported moderate to high risk on 2.01 (range: 0-8) substances, and reported using substances 1.57 (range: 0-20) times before sex over 28 days. Internalized stigma and enacted stigma were associated with greater depressive symptoms, and depressive symptoms were associated with all three indicators of substance use. Moreover, the indirect effects between internalized and enacted stigma with indicators of substance use were significant, suggesting that depressive symptoms partially mediated associations between stigma and substance use. Interventions may be needed to address both stigma and depressive symptoms among PLWH to reduce substance use and support HIV treatment and prevention efforts.

Social and behavioral health responses to COVID-19: lessons learned from four decades of an HIV pandemic

Our public health approaches to addressing COVID-19 are heavily dependent on social and behavioral change strategies to halt transmissions. To date, biomedical forms of curative and preventative treatments for COVID-19 are at best limited. Four decades into the HIV epidemic we have learned a considerable amount of information regarding social and behavioral approaches to addressing disease transmission. Here we outline broad, scoping lessons learned from the HIV literature tailored to the nature of what we currently know about COVID-19. We focus on multiple levels of intervention including intrapersonal, interpersonal, community, and social factors, each of which provide a reference point for understanding and elaborating on social/behavioral lessons learned from HIV prevention and treatment research. The investments in HIV prevention and treatment research far outweigh any infectious disease in the history of public health, that is, until now with the emergence of COVID-19.

Individual Social Capital and the HIV Continuum of Care in a Rural Setting of the Southeast United States

Social capital is associated with the health of people living with HIV, and yet few studies have examined social capital in relation to the HIV continuum of care in the United States. The current study assessed individual social capital within social networks of 251 people living with HIV and residing in a rural area of the southeastern United States. Participants completed computerized self-administered measures that included markers of social capital and disclosure of HIV status to network members. We estimated individual social capital for each relationship identified in the social network interviews and tested regression models at three points along the HIV continuum of care: receiving ART, ART adherence, and HIV viral suppression. Results indicated that one in four participants had not disclosed their HIV status to at least one member of their social network and disclosure was not associated with social capital. Regression models showed that participants with larger social networks and less social capital were more likely to be receiving ART and more likely to have HIV suppressed viral loads. Alcohol use, not social capital, was related to ART non-adherence. Participant's depressive symptomatology was unrelated to any HIV care continuum metrics assessed in this study. We conclude that social capital is drawn upon at critical points along the HIV continuum of care. Interventions should focus on building social capital within social networks and provide support to key network members when patients are transitioning into care, initiating ART and experiencing HIV unsuppressed viral loads.

Alcohol-related beliefs and non-adherence to antiretroviral therapy in Cape Town, South Africa

The life-saving effects of antiretroviral therapy (ART) in treating HIV infection are compromised by alcohol use. A growing body of research shows that both unintentional (e.g., memory lapses) and intentional (e.g., forgoing ART to avoid mixing with alcohol) contribute to ART non-adherence. Beliefs that it is harmful to mix alcohol with ART (alcohol-ART interactive toxicity beliefs) contribute to intentional non-adherence, but their role in overall adherence is not clear. This study conducted a clinic-based survey with 100 men and 193 women (mean age = 36) to examine the prevalence of alcohol-ART interactive toxicity beliefs and whether they contribute to treatment non-adherence in South Africa. One in three (36%, n = 106) participants reported no current alcohol use and 64% (n = 187) reported current alcohol use. The majority of participants, including current alcohol drinkers, endorsed beliefs that it is harmful to mix ART and alcohol, with 57% who currently drink reporting that they forgo taking ART when they are drinking. Participants reported being warned not to mix alcohol and ART from family, friends, and health care providers. In addition, 62% of participants who do not drink, as well as 36% of those who do drink, tell others not to mix alcohol and ART. Mediation modelling found that alcohol use directly predicts ART adherence, and that this relationship is partially mediated by alcohol-ART interactive toxicity beliefs. Health care providers can play a critical role in disputing interactive toxicity beliefs and encouraging patients to take ART even when they are drinking.

When is Enough, Enough? How the Absence of Dose-Determination Trials Impedes Implementation of HIV Behavioral Interventions

Carefully controlled clinical trials have determined that theory-based behavioral interventions delivered by adherence nurses, professional and paraprofessional counselors, and case managers improve ART adherence and viral suppression. However, there are no studies that empirically inform how much intervention is needed for which patient populations and at what cost. This Editorial raises the issue of how a lack of intervention dosing limits interpretation of trial results and impedes implementation, therefore calling for behavioral intervention dose-finding studies.

Health benefits of positive reappraisal coping among people living with HIV/AIDS: A systematic review

People living with HIV/AIDS (PLWHA) often face significant stress, ranging from perceiving identity changes to encountering barriers to daily health behavior engagement. To manage these experiences, many people use positive reappraisal coping (including benefit finding and perceiving growth). Effective coping is highly important for PLWHA; stress reduction has salutary effects on multiple indicators of health. The present systematic review, conducted in PubMed, PsycINFO, and CINAHL, synthesises findings from 33 studies of PLWHA, addressing effects of positive reappraisal on health-related outcomes for adults living with HIV as a chronic illness. Studies were evaluated based on methodological considerations, measurement of key variables, and implications for specific aspects of health. Results suggest that positive reappraisal is often beneficial when dealing with the implications of a potentially traumatic HIV diagnosis on one's identity, although effects may be contextually bound. Implications of these findings are reviewed, emphasizing the importance of positive reappraisal for enhancing health promotion and self-management of HIV. Although the present review is limited by inclusion of multiple disparate outcomes and exclusion of non-English-language articles, these findings inform a comprehensive model of direct and indirect effects of positive reappraisal on emotional, functional, physiological, and behavioural aspects of health useful for guiding future research.

Transgender women and HIV-related health disparities: falling off the HIV treatment cascade

Background Transgender women living with HIV infection experience poorer health outcomes across the HIV continuum of care. While disparities are well established, their underlying mechanisms are not well understood. This study examined the HIV continuum of care (also known as the HIV treatment cascade), including linkage and engagement in care and health status among transgender women and cisgender women and cisgender men living with HIV.

METHOD

Case-control matching was applied to a cohort of 1101 people living with HIV; 70 transgender women living with HIV were matched on years since testing HIV positive with cisgender women and cisgender men. Participants provided measures indicative of the HIV treatment cascade that included linkage and engagement in care, receiving and adhering to antiretroviral therapy (ART), and HIV viral suppression. Common correlates of HIV-related health status: depression symptoms, HIV-related stress, alcohol and drug use, healthcare conspiracy beliefs, medical mistrust, emotional social support and tangible social support, were also assessed.

RESULTS

Transgender women were significantly less likely to receive ART, were less adherent to ART and had poorer HIV viral suppression than cisgender persons. Multivariable models demonstrated that health disparities were predicted by transgender women having poorer tangible social support over and above the other correlates of health outcomes.

CONCLUSION

Tangible support is amenable by interventions such as building and strengthening supportive networks and paraprofessional services. Socially supportive interventions should be considered critical in efforts to decrease HIV health disparities among transgender women.

HIV microaggressions: a novel measure of stigma-related experiences among people living with HIV

Since the beginning of the HIV epidemic stigma has served as a strong barrier to effectively delivering HIV prevention and treatment. Due in part to its complex nature, stigma is difficult to address and novel methods of understanding stigma are needed. Based on formative and empirical research with N = 236 primarily Black men living with HIV, a HIV microaggressions scale was developed and evaluated in order to assess this component of stigma. Factor analysis resulted in a 13-item scale (α = .83) with 3 subscales explaining 51% of the total variance. The microaggressions scale demonstrated convergent validity (with internalized, enacted, and anticipated stigmas) and discriminant validity (with social support). HIV microaggressions was associated with longer gaps since last care appointment and depressive symptoms, and subscales were associated with barriers to accessing health care, disclosure, and HIV care self-efficacy. The HIV microaggressions scale is a novel tool for assessing a critical subcomponent of stigma.

Experiences of HIV-related discrimination and consequences for internalised stigma, depression and alcohol use

Objective: HIV stigma undermines health and well-being of people living with HIV (PLWH). Conceptual work on stigma mechanisms suggests that experiences of stigma or discrimination increase internalised stigma. However, not all PLWH may internalise the HIV discrimination they experience. We aimed to investigate the role of stress associated with events of HIV-related discrimination on internalised HIV stigma, as well as the downstream effects on depressive symptoms and alcohol use severity. Design: 199 participants were recruited from an HIV clinic in the southeastern United States. Main study measures: HIV-related discrimination was assessed using items adapted from measures of enacted HIV stigma and discrimination. Participants rated perceived stress associated with each discrimination item. Internalised HIV stigma was assessed using the internalised stigma subscale of the HIV Stigma Mechanisms Scale. Depressive symptoms were assessed with the Centre for Epidemiological Studies-Depression Index. Alcohol use severity was assessed with the Alcohol Use Disorders Identification Test. Results: In serial mediation models, HIV-related discrimination was indirectly associated with both depressive symptoms and alcohol use severity through its associations with stress and internalised HIV stigma. Conclusions: Understanding the mechanisms through which PLWH internalise HIV stigma and lead to poor health outcomes can yield clinical foci for intervention.
