Social Support and the Mediating Roles of Alcohol Use and Adherence Self-Efficacy on Antiretroviral Therapy (ART) Adherence Among ART Recipients in Gauteng, South Africa

Cognitive Performance, as well as Depression, Alcohol Use, and Gender, predict Anti-Retroviral Therapy Adherence in a South African Cohort of People with HIV and Comorbid Major Depressive Disorder

Depression and cognitive impairment, which commonly coexist in people with HIV (PWH), have been identified as potential barriers to optimal antiretroviral therapy (ART) adherence. We investigated associations between cognitive performance, depression (as well as other sociodemographic, psychosocial and psychiatric variables) and ART adherence in a South African cohort of PWH with comorbid major depressive disorder (MDD). Cognitive performance and ART adherence were assessed at two time points 8 months apart (Nbaseline = 105, Nfollow-up = 81). Adherence was indicated by self-report, objective measures (Wisepill usage and plasma tenofovir-diphosphate levels), and HIV viral suppression. Mixed-effects regression models examined associations across both time points. Univariate models detected no significant associations between cognitive performance (globally and within-domain) and ART adherence. Multivariate modelling showed increased depression severity (β = - 0.54, p < 0.001) and problematic alcohol use (β = 0.73, p = 0.015) were associated with worse adherence as measured subjectively. Being female (OR 0.27, p = 0.048) and having better global cognitive performance (OR 1.83, p = 0.043) were associated with better adherence as indicated by viral suppression. This study identifies poor global cognitive performance, as well as depression and problematic alcohol use, as potential barriers to optimal ART adherence in PWH and comorbid MDD. Hence, clinicians could consider assessing for cognitive deficits, depression, and problematic alcohol use, and should endeavour to provide the appropriate support so as to improve adherence.

Exploring the Association Between Social Support and Hazardous Alcohol Use Among Persons Living with HIV in South Western Uganda

Hazardous alcohol use and psychological distress are common among persons living with HIV (PLWH). In Uganda, HIV prevalence is 6.2% with average pure alcohol consumption per capita of 9.8 L. Social support may mitigate hazardous alcohol use. In a cohort of 443 PLWH, we measured social support using the Duke-UNC functional social support scale and self-reported alcohol consumption using the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), augmented by phosphatidylethanol (PEth). We examined the association between low social support and hazardous alcohol use using multiple logistic regression models. 30% had low social support and 44% had hazardous alcohol use (AUDIT-C ≥ 3 for women and ≥ 4 for men and/or PEth ≥ 50 ng/mL). We did not detect an association between low social support and hazardous alcohol use. Social support may play no role or a minimal role in preventing PLWH from hazardous alcohol use.

A conceptual model of alcohol use and adherence to antiretroviral therapy: systematic review and theoretical implications for mechanisms of action

Alcohol consumption is one of the most prevalent correlates of antiretroviral therapy (ART) adherence, yet causal processes underlying this association remain largely unexplored. The goal of this systematic review was to develop a conceptual model that describes the causal effect of alcohol consumption on ART nonadherence. We reviewed 230 studies that examined the association between alcohol consumption and ART adherence with three primary aims: (1) to replicate and extend previous reviews of the literature, (2) to summarize and critique study designs capable of answering questions about temporal overlap and (3) to summarize potential mechanisms of action. A model of alcohol-associated ART nonadherence was proposed to guide future work, integrating general theories of ART adherence and theory on the psychological and behavioral effects of alcohol intoxication. The conceptual model describes two mechanistic processes-prospective memory impairment and interactive toxicity beliefs/avoidance behaviors-involved in alcohol-associated intentional and unintentional nonadherence, respectively. This model can be used to guide future research on the causal processes involved in the frequently observed correlation between alcohol consumption and adherence.

Stigma in a Collectivistic Culture: Social Network of Female Sex Workers in China

In this egocentric network study, we explored Chinese collectivism in relation to social network characteristics and sex work-related stigma among mid-age female sex workers (FSWs). Respondent-driven sampling was used to recruit 1245 mid-age FSWs from three cities in China. We found that a one standard deviation (SD) increase in FSWs' collectivism was associated with a 0.18 SD decrease in social support (95% CI - 0.32, - 0.04), a 0.20 SD decrease in network effective size (i.e., the diversity of a social network; 95% CI - 0.30, - 0.10), and a 0.21 SD decrease in network betweenness (i.e., the "bridging potential" of egos within their networks; 95% CI - 0.33, - 0.09). Among participants who perceived more sex work stigma, the association between collectivism and FSWs' network betweenness was attenuated. In a collective culture emphasizing group values and honor, belonging to a less interconnected social network may give FSWs a structural advantage to cope with stigma and secure social support.

Project Khanya: results from a pilot randomized type 1 hybrid effectiveness-implementation trial of a peer-delivered behavioural intervention for ART adherence and substance use in HIV care in South Africa

INTRODUCTION

South Africa (SA) has the highest number of people living with HIV (PLWH) globally, and a significant burden of alcohol and other drug use (AOD). Although integrating AOD treatment into HIV care may improve antiretroviral therapy (ART) adherence, this is not typically routine practice in SA or other low-resource settings. Identifying interventions that are feasible and acceptable for implementation is critical to improve HIV and AOD outcomes.

METHODS

A pilot randomized hybrid type 1 effectiveness-implementation trial (N = 61) was conducted to evaluate the feasibility and acceptability of Khanya, a task-shared, peer-delivered behavioral intervention to improve ART adherence and reduce AOD in HIV care in SA. Khanya was compared to enhanced treatment as usual (ETAU), a facilitated referral to on-site AOD treatment. Implementation outcomes, defined by Proctor's model, included feasibility, acceptability, appropriateness and fidelity. Primary pilot effectiveness outcomes were ART adherence at post-treatment (three months) measured via real-time electronic adherence monitoring, and AOD measured using biomarker and self-report assessments over six months. Data collection was conducted from August 2018 to April 2020.

RESULTS AND DISCUSSION

Ninety-one percent of participants (n = 56) were retained at six months. The intervention was highly feasible, acceptable, appropriate and delivered with fidelity (>90% of components delivered as intended by the peer). There was a significant treatment-by-time interaction for ART adherence (estimate = -0.287 [95% CI = -0.507, -0.066]), revealing a 6.4 percentage point increase in ART adherence in Khanya, and a 22.3 percentage point decline in ETAU. Both groups evidenced significant reductions in alcohol use measured using phosphatidylethanol (PEth) (F(2,101) = 4.16, p = 0.01), significantly decreased likelihood of self-reported moderate or severe AOD (F(2,104) = 7.02, p = 0.001), and significant declines in alcohol use quantity on the timeline follow-back (F(2,102) = 21.53, p < 0.001). Among individuals using drugs and alcohol, there was a greater reduction in alcohol use quantity in Khanya compared to ETAU over six months (F(2,31) = 3.28, p = 0.05).

CONCLUSIONS

Results of this pilot trial provide initial evidence of the feasibility and acceptability of the Khanya intervention for improving adherence in an underserved group at high risk for ongoing ART non-adherence and HIV transmission. Implementation results suggest that peers may be a potential strategy to extend task-sharing models for behavioral health in resource-limited, global settings.

Alcohol Use and Antiretroviral Adherence Among Patients Living with HIV: Is Change in Alcohol Use Associated with Change in Adherence?

Alcohol use increases non-adherence to antiretroviral therapy (ART) among persons living with HIV (PLWH). Dynamic longitudinal associations are understudied. Veterans Aging Cohort Study (VACS) data 2/1/2008-7/31/16 were used to fit linear regression models estimating changes in adherence (% days with ART medication fill) associated with changes in alcohol use based on annual clinically-ascertained AUDIT-C screening scores (range - 12 to + 12, 0 = no change) adjusting for demographics and initial adherence. Among 21,275 PLWH (67,330 observations), most reported no (48%) or low-level (39%) alcohol use initially, with no (55%) or small (39% ≤ 3 points) annual change. Mean initial adherence was 86% (SD 21%), mean annual change was - 3.1% (SD 21%). An inverted V-shaped association was observed: both increases and decreases in AUDIT-C were associated with greater adherence decreases relative to stable scores [p < 0.001, F (4, 21,274)]. PLWH with dynamic alcohol use (potentially indicative of alcohol use disorder) should be considered for adherence interventions.

Medication Management Frameworks in the Context of Self-Management: A Scoping Review

PURPOSE

Many individuals take multiple prescribed and unprescribed medications, also known as polypharmacy, which can be problematic. Improving medication self-management is important; however, most medication management frameworks focus on adherence and limit the integration of the core components of self-management. Therefore, the objective of this scoping review was to identify what is reported in the literature on medication management frameworks or models within the context of self-management.

METHODS

Electronic databases (Medline, Embase, CINAHL and Cochrane Library) and grey literature (healthcare and government organization websites) were searched for articles that described a framework or model developed or adapted for medication management, included components of self-management and was published from January 2000 to January 2020. During the screening of titles and abstracts, 5668 articles were reviewed, 5242 were excluded and 426 were then assessed at the full-text level. Thirty-nine articles met the eligibility criteria and were included in the review.

RESULTS

About half of the frameworks were newly developed (n=20), while the other half were adapted from, or applied, a previous model or framework (n=19). The majority of frameworks focused on medication adherence and most of the self-management domains were categorized as medical management, followed by emotional and role management.

CONCLUSION

Medication self-management is a complex process and often impacts multiple areas of an individual's life. It is important for future frameworks to incorporate a comprehensive, holistic conceptualization of self-management that is inclusive of the three self-management domains - medical, emotional and role management.

Alcohol Use and Antiretroviral Therapy Non-Adherence Among Adults Living with HIV/AIDS in Sub-Saharan Africa: A Systematic Review and Meta-Analysis

Antiretroviral therapy (ART) is efficacious in improving clinical outcomes among people living with HIV (PLWH) and reducing HIV transmission when taken regularly. Research examining modifiable factors associated with ART non-adherence is critical for informing novel intervention development in settings with high HIV prevalence. Alcohol use has been linked with ART non-adherence in studies in sub-Saharan Africa; however, no review has pooled estimates across studies. We reviewed studies of alcohol use and ART non-adherence conducted in sub-Saharan Africa. We searched PubMed, CINAHL, EMBASE, and PsycINFO through August 2019 with terms related to ART non-adherence, alcohol use, and sub-Saharan Africa. One author reviewed titles/abstracts (n = 754) and two authors reviewed full texts (n = 308) for inclusion. Discrepancies were resolved by group consensus. Studies were retained if they quantitatively measured associations between alcohol use and ART non-adherence or viral non-suppression. We defined ART non-adherence using the definitions from each parent study (e.g., patients with > 5% missed ART doses during the previous four, seven or 30 days were considered non-adherent). A random effects meta-analysis was conducted to pool associations and we conducted additional analyses to assess between-study heterogeneity and publication bias and sensitivity analyses to determine robustness of our results when considering only certain study designs, alcohol use or ART scales, or studies that used viral non-suppression as their primary outcome. Of 56 articles meeting our inclusion criteria, 32 articles were included in the meta-analysis. All studies measured alcohol use via self-report. ART non-adherence was assessed using self-report, pill counts, or pharmacy records and definition of non-adherence varied depending on the measure used. Individuals who used alcohol had twice the odds of ART non-adherence compared with those who did not use alcohol (34% non-adherence among alcohol users vs. 18% among non-users; pooled odds ratio: 2.25; 95% confidence interval: 1.87-2.69; p < 0.001). We found evidence of a high degree of heterogeneity between studies (Cochrane Q statistic: 382.84, p< 0.001; I² proportion: 91.9%) and evidence of publication bias. However, the magnitude of our pooled odds ratio was consistent across a number of sensitivity analyses to account for heterogeneity and publication bias. In a secondary analysis with studies using viral non-suppression as their primary outcome, we also estimated a statistically significant pooled effect of alcohol use on viral non-suppression (pooled odds ratio: 2.47; 95% confidence interval: 1.58-3.87). Evidence suggests alcohol use is associated with ART non-adherence in Sub-Saharan Africa, potentially hindering achievement of the UNAIDS 90-90-90 HIV treatment targets.

Antiretroviral Therapy Adherence Among People Living With HIV: Directed Content Analysis Based on Information-Motivation-Behavioral Skills Model

Antiretroviral therapy (ART) is one of the complexities of treatment and care for people living with HIV (PLHIV). It is essential to understand the challenges of admitting ART in PLHIV based on the Information Motivation Behavioral skills (IMB) model. This study was conducted using qualitative and directed content analysis on 15 participants. The participants included 10 patients and five health-care providers selected from the behavioral diseases counseling center affiliated with a medical university in southeast of Iran using purposive sampling method. Data were collected through semistructured interviews. Data analysis has led to three main categories—information, motivation, and behavioral skills—and eight subcategories. ART adherence in an Iranian context is like an iceberg that the IMB model can deeply identify underwater and unanticipated motivations and factors that lead to nonadherence. Therefore, it can be useful in designing and developing context-based nonadherence to ART interventions.

Antiretroviral therapy adherence and its determinant factors among people living with HIV/AIDS: a case study in Iran

Objectives

This descriptive-correlational study was conducted on 122 Iranian people living with HIV (PWHIV), who referred to a behavioral diseases counseling center in 2018. The AIDS Clinical Trial Group (ACTG) questionnaire was used to collect the required data. The study aimed to determine the level of medication adherence and its determinants in PWHIV.

Results

About 75.4% (confidence interval 67.2%–82.8%) of the samples had a good combined antiretroviral therapy (cART) adherence and 74.6% (n = 91) of them were sure about the positive effects of medications on their health. Patients reported that most important reasons for medication non-adherence included forgetfulness, high drug dosage, lack of knowledge about ART value, and transportation problems.

Social support, stigma, and the mediating roles of depression on self-reported medication adherence of HAART recipients in China

Discrimination of people living with HIV/AIDS (PLWHA) is a persistent issue in China, which affects their psychological health. However, the association between psychological factors and adherence to highly active antiretroviral therapy (HAART) has not been systematically investigated before. Therefore, this study examined the impact of social support, depression, and medication-taking self-efficacy on ART adherence among PLWHA based on Cha et al.'s model, and included "stigma" to the original model to explain the psychological mechanism. Of the 504 participants receiving HAART, 37.8% had mild-to-severe depression. According to structural equation modeling, social support was directly associated with depression, stigma, and adherence; depression partially mediated the positive relationship between social support and adherence self-efficacy and the negative association between stigma and self-efficacy. The modified and extended Cha et al.'s model had a satisfactory fit. Interventions to improve mental health through mental health services, social support, and enhancement of adherence self-efficacy beliefs are required.

Resilience and HIV: a review of the definition and study of resilience

We use a socioecological model of health to define resilience, review the definition and study of resilience among persons living with human immunodeficiency virus (PLWH) in the existing peer-reviewed literature, and discuss the strengths and limitations of how resilience is defined and studied in HIV research. We conducted a review of resilience research for HIV-related behaviors/outcomes of antiretroviral therapy (ART) adherence, clinic attendance, CD4 cell count, viral load, viral suppression, and/or immune functioning among PLWH. We performed searches using PubMed, PsycINFO and Google Scholar databases. The initial search generated 14,296 articles across the three databases, but based on our screening of these articles and inclusion criteria, n = 54 articles were included for review. The majority of HIV resilience research defines resilience only at the individual (i.e., psychological) level or studies individual and limited interpersonal resilience (e.g., social support). Furthermore, the preponderance of HIV resilience research uses general measures of resilience; these measures have not been developed with or tailored to the needs of PLWH. Our review suggests that a socioecological model of health approach can more fully represent the construct of resilience. Furthermore, measures specific to PLWH that capture individual, interpersonal, and neighborhood resilience are needed.

Adherence to Medication and Physical Activity among People Living with HIV/AIDS

Background:

The aim of this study was to investigate the adherence to medication and Physical Activity (PA) among People Living with HIV (PLHIV).

Materials and Methods:

In the present cross-sectional study, 122 PLHIV were selected. The research tools included the Baecke questionnaire and the AIDS Clinical Trials Group questionnaire. Data were analyzed by independent t test and multiple logistic regression.

Results:

The results of 7- and 30-day recalls showed that 76.21 and 82.23% of patients had proper medication adherence. The mean score of PA in patients was less than the recommended average score in the questionnaire. Furthermore, there was no significant difference observed between the medication adherence and PA.

Conclusions:

Although the adherence to medication was appropriate, nurses and health care providers should increase the level of PA for PLHIV by dealing with the related barriers to live an active life.

Social support, disclosure and stigma and the association with non-adherence in the six months after antiretroviral therapy initiation among a cohort of HIV-positive adults in rural KwaZulu-Natal, South Africa

The World Health Organisation (WHO) recommends antiretroviral treatment (ART) initiation at human immunodeficiency virus (HIV) diagnosis. As ART programmes expand, addressing barriers to adherence is vital. Past mixed findings on the association between social support, stigma and non-disclosure with ART adherence highlights the need for further research. The primary aim of this study was to examine how these factors are associated with ART non-adherence in the six months after ART initiation. The secondary aim was to explore how other factors are associated with non-adherence. We conducted secondary analysis of prospective data from HIV-positive adults initiating ART. Social support, disclosure patterns, perceived stigma and other demographic factors were collected at ART initiation and six months follow-up. Logistic regression models were used to examine factors associated with self-reported ART non-adherence in the last six months and the last month before the six month follow-up (“recent”). Non-adherence in the last six months was twenty-five percent and recent non-adherence was nine percent. There was no association between non-adherence and social support, stigma or non-disclosure of HIV status. In the final model the odds of non-adherence in the last six months were significantly higher for those: with incomplete ART knowledge (aOR 2.10, 95%CI 1.21–3.66); who visited a healthcare provider for conditions other than HIV (aOR1.98, 95%CI 1.14–3.43); had higher CD4 counts at ART initiation (CD4 100–199:aOR 2.50, 95%CI 1.30–4.81; CD4 ≥ 200:aOR 2.85, 95%CI 1.10–7.40;referent CD4 < 100 cells/mm³); had tested HIV-positive in the last year (aOR 2.00, 95%CI 1.10–3.72; referent testing HIV-positive outside the last year); experienced a rash/itching secondary to ART (aOR 2.48, 95%CI 1.37–4.52); and significantly lower for those ≥48 years (aOR 0.65, 95%CI 0.46–0.90). Early non-adherence remains a concern. Incorporation of adherence monitoring and ART knowledge enhancement into appointments for ART collection may be beneficial.

Association of Depressive Symptoms with Lapses in Antiretroviral Medication Adherence Among People Living with HIV: A Test of an Indirect Pathway

Viral suppression, a critical component of HIV care, is more likely when individuals initiate antiretroviral therapy (ART) early in disease progression and maintain optimal levels of adherence to ART regimens. Although several studies have documented the negative association of depressive symptoms with ART adherence, less is known about how depressed mood relates to intentional versus unintentional lapses in adherence as well as the mechanisms underlying this association. The purpose of the current study was to examine the association of depressive symptoms with ART adherence, assessed as a multidimensional construct. Secondarily, this study conducted preliminary indirect path models to determine if medication self-efficacy could explain the depressed mood-adherence relationship. Depressive symptoms were not associated with 95% ART taken, self-reported viral load, deliberate adjustments to ART regimens or skipped ART doses. However, the indirect association of depressive symptoms via decrements in medication self-efficacy was significant for 95% ART taken, self-reported viral load and skipped ART doses, but not deliberate changes to ART regimens. In this sample of HIV-positive outpatients, there is evidence to support medication self-efficacy as a potential mechanism underlying the association between depressive symptoms and ART adherence. Additional longitudinal studies are needed to formally examine medication taking self-efficacy as a mediator.
