RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

COVID-19 poses significant threats to the health of people with underlying chronic conditions, including people living with HIV. The association between subjective well-being and practicing COVID-19 preventive behaviours among people living with HIV is yet to be empirically tested. The objective of the current study was to test the hypothesis that subjective well-being would be associated with engaging in greater COVID-19 preventive behaviours. A sample of 200 women and 72 men (mean age 38.1, SD = 10.4) receiving HIV treatment at a clinic in Cape Town, South Africa completed interview administered surveys of health behaviours and three dimensions of subjective well-being: emotional, social and psychological well-being. Hierarchical regression models were performed to test subjective well-being as predictors of COVID-19 preventive behaviours adjusting for age, sex, education, TB history, antiretroviral therapy adherence, and concern about contracting COVID-19. Results showed that psychological well-being, along with concerns over COVID-19, predicted greater COVID-19 preventive behaviours over and above the other variables in the model, accounting for 9.2% of the variance. Results support incorporating interventions to foster psychological well-being into existing clinical services for people living with HIV to improve clusters of health behaviours.

RESUMO

Background: Long-acting reversible contraceptives (LARCs), which include the subdermal contraceptive implant and intrauterine contraception, offer women safe, highly effective, long-term pregnancy prevention, and have expanded contraceptive options. The implant greatly expands LARC options for South African women as it is available free of charge at public health facilities, but little is known about factors associated with its uptake. This study describes factors associated with the intention to use the implant, including knowledge and beliefs about the implant and perceived outcome expectancies of implant use among women in Cape Town, South Africa. Methods: Between 2015 and 2016, the authors conducted a quantitative, cross-sectional survey among adult women attending a public, primary health clinic in Cape Town, South Africa. Using a structured questionnaire, they measured knowledge, awareness, and attitudes, perceived outcome expectancy, and the intention to use the contraceptive implant in future among the women. Results: The authors surveyed 481 women (mean age 29.1 years). Most of the participants (n = 364, 75.6%) had heard about the implant, 45 (9.4%) were currently using it, and 97 (20.2%) intended to use it in the future. Knowledge about the safety of the implant, beliefs about its effectiveness, and the ease of insertion and removal, and support from intimate partners were positively associated with the current use and intentions to use the implant in the future. Conclusions: Limited knowledge of the implant, having completed secondary schooling, support from partner for women to use implant and the perceived outcome expectancies of using the implant were factors significantly associated with the intention to use the implant. Ensuring that the contraception information is available in all South African languages, regardless of education levels in women, and that comprehensive contraception education and counseling is provided during all family planning might help improve the uptake of contraceptives, including the use of the implant in the country.

RESUMO

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.

RESUMO

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.

RESUMO

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.
