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.

Unannounced phone-based pill counts for monitoring antiretroviral medication adherence in South Africa.

BACKGROUND: Unannounced phone-based pill counts (UPC) are an objective measure of medication adherence that may be used in resource limited settings. The current study reports the feasibility and validity of UPC for monitoring antiretroviral therapy (ART) adherence among people living with HIV in South Africa. People living with HIV (N = 434) in an economically impoverished township and receiving ART for at least 3-months completed: two UPC in a one-month period; measures of clinic and medication experiences; and provided blood samples for HIV viral load and CD4 testing. Analyses compared two methods for managing values of over-dosing (> 100%), specifically censoring values to 100% (> 100% = 100%) vs. subtracting over-dosing from two months of perfect adherence (200% - > 100% value). RESULTS: Findings showed that two UPC calls were successfully completed with 91% of participants in a one-month period. The average number of call attempts needed to reach participants was 2.4. Results showed that lower UPC adherence was significantly associated with male gender, alcohol use, higher HIV viral loads, lower CD4 cell counts, running out of ART, and intentionally not taking ART. Comparisons of methods for adjusting over-dosing found subtraction yielding a better representation of the data than censoring. CONCLUSIONS: UPC were demonstrated feasible and valid with patients receiving ART in a resource limited setting and offers a viable method for objectively measuring ART adherence in these settings.

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.

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.

A novel psychometric approach to assessing intersectional hiv stigma: the geometric intersectional stigma scales.

Recent advances in stigma theories have emphasized intersectionality, but there are currently few approaches to measuring intersectional HIV stigma. Here we present a novel approach to assessing intersectional HIV stigma. Black/African American sexual minority men living with HIV (N = 437) completed newly developed measures of enacted and anticipated stigma along with a battery of instruments to examine construct validity. For each endorsed stigma item, participants rated three personal attributes ascribed to the stigma experiences, specifically race, same-sex sexual behavior, and HIV status. Based on the notion that intersecting orthogonal dimensions such as attributions for experiencing stigma can be conceptualized geometrically, we used the Pythagorean Theorem to calculate intersectional stigma scores. Results showed that the enacted and anticipated stigma scales and the assessment of intersectional stigma attributes demonstrated acceptable response rates, internal consistency and a pattern of associations with correlates that suggests construct validity. In separate tests of construct validity, regression models predicting medication adherence indicated varied results among stigma measures, demonstrating clear advantages to separating the assessment of stigma experiences from the attributes to which stigma experiences are ascribed. Findings from this geometric approach to assessing intersectional HIV stigma were promising and warrant further investigation.

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.

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.

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.

Perceived HIV stigma and HIV testing among men and women in rural Uganda: a population-based study.

BACKGROUND: Stigma is a formidable social structural barrier to HIV testing, and yet the effect of stigma on HIV testing is rarely examined at the community level. We aimed to examine the geospatial relationships of perceived HIV stigma and HIV testing among men and women living in rural Uganda. METHODS: Women and men (aged ≥18 years or emancipated minor) residing in rural areas of Uganda who self-identified as HIV negative completed interviews that included measures of HIV testing history and how participants perceived HIV stigma. We used geospatial cluster analyses to identify areas of higher perceived stigma and lower perceived stigma and the geographical dispersion of these areas. We used Poisson regression models stratified by gender to test individual-level and community-level perceived stigma in relation to frequency of HIV testing in the previous 2 years. FINDINGS: Between Nov 25, 2015, and May 26, 2017, we interviewed 9740 participants (4359 [45%] men and 5381 [55%] women]), among whom 940 (9%) had never been tested for HIV, and among those who had been tested, 1131 (12%) had not been tested in the previous 2 years. Men (3134 [72%] of 4359) were less likely to have been tested in the past 2 years than women (4535 [84%] of 5381) were (p<0·001). We used Poisson regression models, reporting B coefficients, to test study hypotheses regarding the effects of individual-level and community-level stigma on HIV testing frequency counts. Multilevel modelling showed that women showed significant individual-level (B=-0·173, p<0·001) and community-level (B=-0·223, p<0·001) associations between lower stigma predicting higher rates of HIV testing. For men, lower individual-level perceived stigma was also associated with higher testing frequency (B=-0·030, p=0·018), whereas higher community-level perceived stigma was associated with higher testing frequency (B=0·077, p=0·008). INTERPRETATION: Our results suggest that perceived HIV stigma at the community level exerts a differential influence on testing for women and men. HIV testing campaigns that are targeted to men and women in rural Uganda will require gender tailoring to fit local contexts. FUNDING: US National Institute of Mental Health.

Income Inequality, HIV Stigma, and Preventing HIV Disease Progression in Rural Communities.

Antiretroviral therapies (ART) suppress HIV replication, thereby preventing HIV disease progression and potentially preventing HIV transmission. However, there remain significant health disparities among people living with HIV, particularly for women living in impoverished rural areas. A significant contributing factor to HIV-related disparities is a stigma. And yet, the relative contributions of stigma, gender, socio-economics, and geography in relation to health outcomes are understudied. We examined the associations of internalized stigma and enacted stigma with community-level income inequality and HIV viral suppression-the hallmark of successful ART-among 124 men and 74 women receiving care from a publicly funded HIV clinic serving rural areas with high-HIV prevalence in the southeastern US. Participants provided informed consent, completed computerized interviews, and provided access to their medical records. Gini index was collected at the census tract level to estimate community-level income inequality. Individual-level and multilevel models controlled for point distance that patients lived from the clinic and quality of life, and included participant gender as a moderator. We found that for women, income inequality, internalized stigma, and enacted stigma were significantly associated with HIV suppression. For men, there were no significant associations between viral suppression and model variables. The null findings for men are consistent with gender-based health disparities and suggest the need for gender-tailored prevention interventions to improve the health of people living with HIV in rural areas. Results confirm and help to explain previous research on the impact of HIV stigma and income inequality among people living with HIV in rural settings.
