Alcohol-related intentional nonadherence to antiretroviral therapy among people living with HIV, Cape Town, South Africa

HealthCall: Smartphone Enhancement of Brief Interventions to Improve HIV Medication Adherence Among Patients in HIV Care

Heavy drinking among people living with HIV (PLWH) reduces ART adherence and worsens health outcomes. Lengthy interventions are not feasible in most HIV care settings, and patients infrequently follow referrals to outside treatment. Utilizing visual and video features of smartphone technology, we developed HealthCall as an electronic means of increasing patient involvement in a brief intervention to reduce drinking and improve ART adherence. The objective of the current study is to evaluate the efficacy of HealthCall to improve ART adherence among PLWH who drink heavily when paired with two brief interventions: the National Institute on Alcoholism and Alcohol Abuse (NIAAA) Clinician's Guide (CG) or Motivational Interviewing (MI). Therefore, we conducted a 1:1:1 randomized trial among 114 participants with alcohol dependence at a large urban HIV clinic. Participants were randomized to one of three groups: (1) CG only (n = 37), (2) CG and HealthCall (n = 38), or (3) MI and HealthCall (n = 39). Baseline interventions targeting drinking reduction and ART adherence were ~ 25 min, with brief (10-15 min) booster sessions at 30 and 60 days. The outcome was ART adherence assessed using unannounced phone pill-count method (possible adherence scores: 0-100%) at 30-day, 60-day, 3, 6, and 12 months. Analyses were conducted using generalized linear mixed models with pre-planned contrasts. Of the 114 enrolled patients, 58% were male, 75% identified as Black/African American, 28% were Hispanic, and 62% had less than a high school education. The mean age was 47.5 years (standard deviation [SD]  10 years) and the mean number of years since they were diagnosed with HIV was 18.6 (SD 7.6). Participants assigned to HealthCall to extend the CG had increased levels of ART adherence at 60-day and 6-month follow-up (compared to CG only), although there was no statistically significant difference by 12-month follow-up. Participants who were assigned to HealthCall to extend the MI never had statistically significant higher levels of ART adherence. These results suggest that the use of a smartphone app can be used to initially extend the reach of a brief drinking intervention to improve ART adherence over a short period of time; however, sustained long-term improvements in ART adherence after intervention activity ends remains a challenge.

Epidemiology of alcohol use and alcohol use disorders among people living with HIV on antiretroviral therapy in Northwest Tanzania: implications for ART adherence and case management

Alcohol use disorders (AUD) among people living with HIV (PLHIV) are associated with poor health outcomes. This cross-sectional study examined current alcohol use and AUD among 300 PLHIV on ART at four HIV care centres in Northwest Tanzania. Participants' data were collected using questionnaires. Alcohol use was assessed using Alcohol Use Disorders Identification Test (AUDIT). Logistic regression was used to examine associations between each outcome (current drinking and AUD) and sociodemographic and clinical factors. Association between alcohol use and ART adherence was also studied. The median age of participants was 43 years (IQR 19-71) and 41.3% were male. Twenty-two (7.3%) participants failed to take ART at least once in the last seven days. The prevalence of current drinking was 29.3% (95% CI 24.2-34.8%) and that of AUD was 11.3% (8.2%-15.5%). Males had higher odds of alcohol use (OR 3.03, 95% CI 1.79-5.14) and AUD (3.89, 1.76-8.60). Alcohol use was associated with ART non-adherence (OR = 2.78, 1.10-7.04). There was a trend towards an association between AUD and non-adherence (OR = 2.91, 0.92-9.21). Alcohol use and AUD were common among PLHIV and showed evidence of associations with ART non-adherence. Screening patients for alcohol use and AUD in HIV clinics may increase ART adherence.

Pathways to Poor Adherence to Antiretroviral Therapy Among People Living with HIV: The Role of Food Insecurity and Alcohol Misuse

Daily adherence to antiretroviral therapy (ART) increases the length and quality of life of people living with HIV (PLHIV). We explored whether socioeconomic status directly impacts ART adherence and whether part of the effect is mediated by pathways through alcohol misuse or food insecurity. A cross-sectional study was conducted in Rio de Janeiro/Brazil (November/2019 to March/2020) with PLHIV aged ≥ 18 years. Validated instruments were used to measure alcohol use, food insecurity, and ART adherence. Using structural equation modeling we assessed the direct and indirect effects of variables on ART adherence. Participants reported significant challenges: hunger: 12%, alcohol use: 64%, and missing ART doses: 24%. Results showed that lower socioeconomic status increased poor adherence and that this effect was mediated through higher food insecurity. Alcohol misuse also increased poor adherence through a strong direct effect. Providing socio-economic support coupled with interventions to mitigate alcohol's harmful impact can aid HIV care.

Universal HIV Testing and Treatment With Patient-Centered Care Improves ART Uptake and Viral Suppression Among Adults Reporting Hazardous Alcohol Use in Uganda and Kenya

OBJECTIVES

Determine whether patient-centered, streamlined HIV care achieves higher antiretroviral therapy (ART) uptake and viral suppression than the standard treatment model for people with HIV (PWH) reporting hazardous alcohol use.

DESIGN

Community cluster-randomized trial.

METHODS

The Sustainable East Africa Research in Community Health trial (NCT01864603) compared an intervention of annual population HIV testing, universal ART, and patient-centered care with a control of baseline population testing with ART by country standard in 32 Kenyan and Ugandan communities. Adults (15 years or older) completed a baseline Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) and were classified as no/nonhazardous (AUDIT-C 0-2 women/0-3 men) or hazardous alcohol use (≥3 women/≥4 men). We compared year 3 ART uptake and viral suppression of PWH reporting hazardous use between intervention and control arms. We compared alcohol use as a predictor of year 3 ART uptake and viral suppression among PWH, by arm.

RESULTS

Of 11,070 PWH with AUDIT-C measured, 1723 (16%) reported any alcohol use and 893 (8%) reported hazardous use. Among PWH reporting hazardous use, the intervention arm had higher ART uptake (96%) and suppression (87%) compared with control (74%, adjusted risk ratio [aRR] = 1.28, 95% CI: 1.19 to 1.38; and 72%, aRR = 1.20, 95% CI: 1.10 to 1.31, respectively). Within arm, hazardous alcohol use predicted lower ART uptake in control (aRR = 0.86, 95% CI: 0.78 to 0.96), but not intervention (aRR = 1.02, 95% CI: 1.00 to 1.04); use was not predictive of suppression in either arm.

CONCLUSIONS

The Sustainable East Africa Research in Community Health intervention improved ART uptake and viral suppression among PWH reporting hazardous alcohol use and eliminated gaps in ART uptake between PWH with hazardous and no/nonhazardous use. Patient-centered HIV care may decrease barriers to HIV care for PWH with hazardous alcohol use.

Assessing the Feasibility of Economic Approaches to Prevent Substance Abuse Among Adolescents: Protocol for a Mixed Methods Study

BACKGROUND

Adolescent alcohol and drug use (ADU) is a significant public health challenge. Uganda, one of the poorest countries in Sub-Saharan Africa (SSA), has the second-highest rate of per capita alcohol consumption in SSA, and over one-third of Ugandan adolescents have used alcohol in their lifetime (over 50% of them engage in heavy episodic drinking). These estimates further increase in fishing villages, a key HIV-vulnerable population, where ADU is normative. However, few studies have assessed ADU among adolescents and youths living with HIV despite their increased risk for ADU and its impact on engagement in HIV care. Moreover, data on risk and resilience factors for ADU are scarce as only few studies evaluating ADU interventions in SSA have reported positive outcomes. The majority have been implemented in school settings, potentially excluding adolescents in fishing communities with high school dropout rates, and none have targeted risk factors including poverty and mental health, which are rampant among adolescents and youths living with HIV and their families, undermine their coping skills and resources, and have been associated with increased risk for ADU among them.

OBJECTIVE

We propose a mixed methods study with a sample of 200 adolescents and youths living with HIV (aged 18-24 years) seen at 6 HIV clinics in southwestern Uganda's fishing communities to (1) examine the prevalence and consequences of ADU and identify the multilevel risk and resilience factors associated with ADU among them and (2) explore the feasibility and short-term effects of an economic empowerment intervention on ADU among them.

METHODS

This study comprises four components: (1) focus group discussions (FGDs) with adolescents and youths living with HIV (n=20) and in-depth qualitative interviews with health providers (n=10) from 2 randomly selected clinics; (2) a cross-sectional survey with 200 adolescents and youths living with HIV; (3) a randomized controlled trial with a subgroup of adolescents and youths living with HIV (n=100); and (4) 2 postintervention FGD with adolescents and youths living with HIV (n=10 per group).

RESULTS

Participant recruitment for the first qualitative phase has completed. As of May 4, 2023, ten health providers from 6 clinics have been recruited, provided written consent to participate, and participated in in-depth qualitative interviews. Two FGDs was conducted with 20 adolescents and youths living with HIV from 2 clinics. Data transcription, translation, and analysis of qualitative data has commenced. The cross-sectional survey will commence shortly after and dissemination of the main study findings is targeted for 2024.

CONCLUSIONS

Our findings will advance our understanding of ADU among adolescents and youths living with HIV and inform the design of future interventions to address ADU among them.

Social Determinants of Alcohol and Other Drug Misuse Among Women Living with HIV in Economically Underserved Communities in Cape Town, South Africa: A Cross-Sectional Study

This study aimed to understand how social determinants-the economic and social factors that affect health and well-being-are associated with self-reported and biological alcohol and other drug misuse in South Africa among women living with HIV. Logistic regression analyses were performed using baseline data from an implementation science trial conducted from 2015 to 2018 with 480 Black and Coloured women who were living with HIV and reported recent alcohol or other drug misuse. Educational attainment, type of housing, access to running water, food insecurity, and housing instability were examined. Women with higher education had reduced odds of any drug misuse-both biological (aOR: 0.53; 95% CI: 0.33-0.84) and self-reported (aOR: 0.37; 95% CI: 0.22-0.64). Women living in formal housing had increased odds of a positive alcohol screening test (aOR: 1.92; 95% CI: 1.16-3.18) and women with housing instability had increased odds of self-reported alcohol misuse-daily (aOR: 1.99; 95% CI: 1.18-3.35) and weekly (aOR:1.91; 95% CI: 1.19-3.07). Food insecurity was associated with reduced odds of self-reported alcohol misuse (aOR: 0.40; 95% CI: 0.25-0.64) and increased odds of self-reported drug misuse (aOR: 2.05; 95% CI: 1.16-3.61). These findings indicate the complexity of the relationship between social determinants and alcohol and other drug misuse, and may have implications for addressing social and structural determinants as part of multilevel interventions focused on reducing alcohol and other drug misuse among key populations of women in South Africa.

Supporting Treatment for Anti-Retroviral Therapy (START) Together: Protocol for a pilot, randomized, couple-based intervention to promote women's ART adherence and men's engagement in HIV care in KwaZulu-Natal, South Africa

Background

South Africa currently has the greatest number of people with HIV globally. The country has not yet met its 95-95-95 goals, with different gaps in the HIV care cascade for women and men. This paper reports on a protocol to pilot test a couple-based intervention designed to improve women's antiretroviral therapy (ART) adherence and men's engagement in care in heterosexual couples living in the Vulindlela area of KwaZulu-Natal, South Africa. Study goals are two-fold: (1) assess the acceptability, feasibility, and fidelity of the experimental intervention, START Together, and (2) collect efficacy data on START Together for women's ART adherence, men's engagement in HIV care, and the couple's relationship functioning.

Methods

Women (N = 20) who were not engaged with ART adherence (defined via self-reported ART difficulties, record of missed clinic visits, or viral non-suppression) are the target patients; male partners are not required to know or disclose their HIV status to be part of the study. Couples are randomized 1:1 to the experimental treatment (START Together) or treatment as usual (referrals to the local clinic to support ART adherence or any other HIV-related care). START Together is a 5-session intervention based in cognitive-behavioral couple therapy, which is a skill-based intervention focusing on communication and problem-solving skills, and Life Steps, a problem-solving intervention identifying barriers and solutions to medication adherence. Couples are assessed at baseline, post-treatment (8 weeks post-randomization), and follow-up (12 weeks post-randomization).

Conclusion

This study will provide preliminary implementation and efficacy data on whether this novel approach has potential to improve women and men's HIV and healthcare-related needs.

Association Between ART Adherence and Mental Health: Results from a National HIV Sero-Behavioural Survey in South Africa

This paper assesses the levels of antiretroviral treatment (ART) adherence and mental health distress among study participants in a national behavioural HIV-sero prevalence study South Africa. The study was a cross-sectional population-based multi-stage stratified cluster random survey, (SABSSM V, 2017). Structured questionnaires were used to collect information on socio-demographics, HIV knowledge, perceptions, HIV testing and HIV treatment history. Study participants were tested for HIV infection, antiretroviral use, viral suppression, and ART drug resistance. A total of 2155 PLHIV aged 15 years or older who were on ART were included in the study. Incidence of either moderate or severe mental health distress was 19.7%. Self-reported ART adherence among study participants with no, mild, moderate, or severe mental distress was 82%, 83%, 86% and 78%, respectively. The adjusted odds ratio for ART non-adherence was 0.58 (95% CI 0.24; 1.40) for mild mental distress, 0.82 (95% CI 0.35; 1.91) for moderate mental distress and 2.19 (95% CI 1.14; 4.19) for severe mental distress groups compared to the no mental health distress group. The other factors that were associated with ART non-adherence in adjusted models included education level, alcohol use and province/region of residence. The study revealed that mental health remains a challenge to ART adherence in South Africa. To improve ART adherence, HIV continuum of care programs should include screening for mental health among people living with HIV.

Impact of attitudes and beliefs on antiretroviral treatment adherence intention among HIV-positive pregnant and breastfeeding women in Zambia

OBJECTIVE

The aim of this study was to investigate if attitudes or behavioral beliefs about antiretroviral therapy (ART) influence ART adherence intention among pregnant and breastfeeding women in Zambia.

METHODS

We recruited 150 HIV-positive women receiving ART in urban (Lusaka) and rural (Sinazongwe) districts of Zambia. Generalized modified Poisson regression models were used to assess the extent to which adherence intention was influenced by attitude toward ART or behavioral beliefs about ART.

RESULTS

Intention to adhere to ART differed significantly by income, knowledge about HIV transmission, attitudes, and behavioral beliefs (all Ps < .05). In addition, strong intention to adhere to ART differed by urban (69%) and rural (31%) place of residence (P ≤ .01). In adjusted models, women in the weak adherence intention group were more likely to be older, have less knowledge about HIV transmission, and have a more negative attitude toward ART (PR 0.74; 95% CI 0.67-0.82). Behavioral belief about ART, however, was significant in unadjusted model (PR 0.85; 95% CI 0.76-0.94) but not significant after adjusting for covariates such as age, knowledge of transmission, and district locality.

CONCLUSION

Compared to behavioral beliefs, attitudes about ART were more influential for intention to adhere. This knowledge will help inform effective and appropriate ART counseling for pregnant and breastfeeding women at different points along their ART time course.

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.

Associations between alcohol use and HIV care cascade outcomes among adults undergoing population-based HIV testing in East Africa

OBJECTIVE

To assess the impact of alcohol use on HIV care cascade outcomes.

DESIGN

Cross-sectional analyses.

METHODS

We evaluated HIV care cascade outcomes and alcohol use in adults (≥15 years) during baseline (2013--2014) population-based HIV testing in 28 Kenyan and Ugandan communities. 'Alcohol use' included any current use and was stratified by Alcohol Use Disorders Identification Test-Concise (AUDIT-C) scores: nonhazardous/low (1--3 men/1--2 women), hazardous/medium (4--5 men/3--5 women), hazardous/high (6--7), hazardous/very-high (8--12). We estimated cascade outcomes and relative risks associated with each drinking level using targeted maximum likelihood estimation, adjusting for confounding and missing measures.

RESULTS

Among 118 923 adults, 10 268 (9%) tested HIV-positive. Of those, 10 067 (98%) completed alcohol screening: 1626 (16%) reported drinking, representing 7% of women (467/6499) and 33% of men (1 159/3568). Drinking levels were: low (48%), medium (34%), high (11%), very high (7%). Drinkers were less likely to be previously HIV diagnosed (58% [95% CI: 55--61%]) than nondrinkers [66% (95% CI: 65-67%); RR: 0.87 (95% CI: 0.83-0.92)]. If previously diagnosed, drinkers were less likely to be on ART [77% (95% CI: 73-80%)] than nondrinkers [83% (95% CI 82-84%); RR: 0.93 (95% CI: 0.89-0.97)]. If on ART, there was no association between alcohol use and viral suppression; however, very-high-level users were less likely to be suppressed [RR: 0.80 (95% CI: 0.68-0.94)] versus nondrinkers. On a population level, viral suppression was 38% (95% CI: 36-41%) among drinkers and 44% (95% CI: 43-45%) among nondrinkers [RR: 0.87 (95% CI 0.82-0.94)], an association seen at all drinking levels.

CONCLUSION

Alcohol use was associated with lower viral suppression; this may be because of decreased HIV diagnosis and ART use.

Stigmatisation of alcohol use among people receiving antiretroviral therapy for HIV infection, Cape Town, South Africa

Antiretroviral therapy (ART) effectively treats HIV infection, with improved longevity and quality of life among people living with HIV. Alcohol use, however, remains a robust barrier to ART. This study, for the first time, examined the effects of the stigmatisation of alcohol use on ART adherence. Patients receiving ART in Cape Town, South Africa who currently drink alcohol (N = 187) and those who do not drink alcohol (N = 106) completed measures of alcohol use, alcohol-ART adherence, and alcohol-ART stigma. Participants also provided permission to access their most recent HIV viral load from clinic medical records. Results of a mediation model demonstrated significant detrimental effects of alcohol use on ART adherence. In addition, the indirect effects of alcohol use on ART adherence through alcohol-ART stigma was also significant, indicating that alcohol-ART stigma at least in part mediates the association between alcohol use and ART adherence. The same pattern of results was observed in relation to HIV viral load obtained from medical records. Interventions designed to address alcohol use as a barrier to ART adherence should incorporate alcohol-ART stigma as a barrier to adherence as well as a barrier to participating in adherence interventions.

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.
