Baseline predictors of three types of antiretroviral therapy (ART) adherence: A 2-year follow-up

Associations Between Anxiety and Adherence to Antiretroviral Medications in Low- and Middle-Income Countries: A Systematic Review and Meta-analysis

Untreated mental health disorders among people living with HIV (PLHIV) may prevent low- and middle-income countries (LMICs) from achieving the UNAIDS 90-90-90 targets. Anxiety disorders may be associated with decreased adherence to antiretroviral therapy (ART). We sought to review and meta-analyze studies estimating associations between anxiety and ART adherence in LMICs. We searched PubMed, PsychINFO, CINAHL and EMBASE for relevant studies published before July 18, 2018. We defined anxiety as reported anxiety scores from screening questionnaires or having a clinical diagnosis of an anxiety disorder, and poor ART adherence as missed doses, poor visit attendance, or scores from structured adherence questionnaires. We used a random effects model to conduct a meta-analysis for calculating a pooled odds ratio, and conducted sensitivity analyses by time on ART, anxiety evaluation method, and study region. From 472 screened manuscripts, thirteen studies met our inclusion criteria. Eleven studies were included in the meta-analysis. PLHIV who reported anxiety had 59% higher odds of poor ART adherence compared with those who did not report anxiety disorder (pooled odds ratio [pOR]: 1.59, 95% confidence interval [CI] 1.29-1.96, p < 0.001). When excluding PLHIV who initiated ART within 6 months, reported anxiety remained strongly associated with poor ART adherence (pOR: 1.61, 95% CI 1.18-2.20, p = 0.003). Among PLHIV in LMICs, reported anxiety was associated with poor ART adherence. This association persisted after the ART initiation period. Increased resources for mental health may be important for achieving virologic suppression in LMICs.

HIV Disclosure: HIV-positive status disclosure to sexual partners among individuals receiving HIV care in Addis Ababa, Ethiopia

Introduction

Disclosure of HIV status to sexual partners can help HIV prevention efforts and enable HIV positive people to receive social support, as well as increasing access and adherence to treatment. This study was conducted to determine the rate, processes, outcomes, and correlates of HIV status disclosure to sexual partners among HIV positive individuals.

Method

A cross-sectional study was conducted between September and November 2015 at two HIV outpatient clinics in Addis Ababa, Ethiopia. Data were collected using an interviewer- administered semi-structured questionnaire. Logistic analysis was used to determine the independent correlates of serostatus disclosure.

Results

Of 742 participants, (371 men and 371 women), 727 (98%) were on antiretroviral therapy and 676 (91.1%) had at least one sexual partner since their HIV diagnosis, of whom 558 (82.5%) had disclosed their HIV status to their most recent sexual partner. Of those who reported having disclosed their status to their most recent sexual partner, 82 (14.7%) had at least one unprotected sexual encounter with the partner, after HIV diagnosis but prior to disclosure. The most commonly reported initial outcome of disclosure was gaining emotional and/or financial support. Some (11.3%) also reported that their disclosure immediately initiated their partner for HIV testing. Negative outcomes to disclosure, such as stigma and discrimination, were more common among females (26.2%) compared to males (12.7%). In the multiple regression analysis, disclosure was associated with greater condom use, greater social support, knowing the partner’s HIV status, having a good relationship with the partner, and cohabiting with the partner.

Conclusion

HIV disclosure was common amongst participants, although sometimes delayed, with possible consequences for onward transmission. Fear of negative outcomes, such as verbal abuse and physical violence, were major barriers to disclosure. Efforts to support disclosure have the potential to contribute to HIV control and prevention by encouraging safer sexual practice, initiating partners for HIV testing, and enhancing support for people living with HIV.

Depression, Social Support, and Adherence to Antiretroviral Therapy Among People Living With HIV in Guangxi, China: A Longitudinal Study

Depression can result in poor adherence to antiretroviral therapy (ART) among people living with HIV (PLHIV), and social support can help mitigate the negative relationship. However, little is known about how depression and social support synergistically influence ART adherence over time. The current study aims to explore longitudinal associations between them and examine which sources of social support can play a mediating role between depression and ART adherence over time. A randomized controlled clinical trial was conducted between 2013 and 2016 in Guangxi, China. The study sample was composed of 319 PLHIV who were randomized into control condition and provided data at baseline and at least one of the six follow-ups. The results revealed negative associations of depression with ART adherence over time, and a mediating effect of perceived support from spouse/partner or children. Interventions to promote ART adherence should focus on strengthening PLHIV's relationships with their spouse/partner and children, promoting collaborative provider-patient relationships, and enhancing peer support among PLHIV.

The Prevalence of HIV Load Suppression and Related Factors Among Patients on ART at Phedisong 4 Clinic, Pretoria, South Africa

Background:

Globally, the benefits of viral load suppression in improving the lives of people living with HIV/AIDS have been established. In 2010, the South African Government decentralised ART to the primary care level. This study intended to determine the effect of this decentralisation in achieving viral load suppression among patients.

Objective:

To determine the prevalence of HIV viral load suppression and factors related to the suppression among patients initiated on ART at Pedisong 4 clinic, Tshwane District in Pretoria.

Methods:

A prospective cohort study was conducted on 98 patients initiated on ART between 01 November 2012 and 30 April 2013. Based on the viral load results, they were divided into those who achieved Viral Load Suppression (VLS), and those who did not (NVLS). Analyses were done using SAS® (version 9.2) for Microsoft software. A p < 0.05 was considered significant.

Results:

Ninety patients (91.8%; 95%CI, 84.7% – 95.8%) achieved viral load suppression while eight (8.2%; 95%CI, 4.2% – 15.3%), did not. Of the 98 patients, 63 (64%) were female. In the NVLS group, the female to male ratio was 7:1 (p = 0.038). There was no relationship between viral load suppression and patients’ baseline characteristics, behavioural characteristics and clinical characteristics (p > 0.05). ART adherence reported in both patient groups was ≥ 87.0%.

Conclusion:

There was good viral load suppression in patients initiated on ART at Pedisong 4 clinic. Patients’ baseline, behavioural and clinical characteristics were not related to viral load suppression, necessitating further large sample size studies in various health facilities.

A Novel Integrated Cognitive-Behavioral Therapy for Anxiety and Medication Adherence Among Persons Living With HIV/AIDS

Persons living with HIV/AIDS (PLHIV) are able to live full lifespans after infection, however, rates of anxiety disorders among this population are elevated compared to national samples. Importantly, these anxiety symptoms and disorders have a negative effect on medication adherence, quality of life and other psychological disorders, such as depression. In order to reduce the impact of anxiety among PLHIV, a six-session transdiagnostic CBT-based treatment manual for anxiety among PLHIV named the HIV/Anxiety Management-Reduction Treatment (HAMRT) was developed and implemented. The current manuscript discusses the content of this manual as well as results from three cases examining the impact of HAMRT. Results indicated that HAMRT was effective in reducing symptoms of anxiety, anxiety sensitivity, depression, and negative affect among our sample. Additionally, results indicated that HAMRT was effective in increasing HIV medication adherence as well as quality of life. Results are discussed in terms of the potential utility of an anxiety-reduction therapy program aimed at increasing medication adherence among PLHIV.

Anxiety symptoms and disorders among adults living with HIV and AIDS: A critical review and integrative synthesis of the empirical literature

There are over 35 million people worldwide infected with the Human Immunodeficiency Virus (HIV) and its progression to Acquired Immunodeficiency Syndrome (AIDS; WHO, 2014). With the advent of combined antiretroviral therapy (i.e., cART) in 1996, persons living with HIV/AIDS (PLWHA) now have much longer life expectancies. However, living with HIV remains challenging, as it is associated with a number of significant and recurrent (chronic) stressors including physical pain, side effects of cART, social stigma, and discrimination, among other social stressors. Presumably, as a result of these types of stressors, a disproportionately high number of PLWHA struggle with clinically-significant psychiatric symptoms and disorders. Although much scientific and clinical attention has focused on depressed mood and psychopathology among PLWHA, there has been comparably less focus on anxiety and its disorders. The paucity of work in this area is concerning from a public health perspective, as anxiety symptoms and disorders are the most common class of psychiatric disorders and often maintain a large negative impact on life functioning.

The applicability of the Theory of Planned Behaviour in predicting adherence to ART among a South African sample

We sought to determine the extent to which the Theory of Planned Behaviour (TPB) was applicable in predicting medication adherence among South Africans receiving antiretroviral therapy (ART). Regression analyses revealed that the linear combination of attitudes towards adherence, perceived behavioural control and perceived group norms explained 12 percent of the variance in intentions to adhere to ART. We also found a non-significant relationship between intentions to adhere to treatment and self-reported adherence. The results call into question the extent to which TPB is helpful in understanding a health-promoting behaviour such as medication adherence among South Africans receiving ART.

Intentionality of medication non-adherence among individuals living with HIV/AIDS in Hong Kong

Adherence to antiretroviral therapy is essential to treatment success for individuals living with HIV/AIDS. Despite the wealth of studies in examining antiretroviral non-adherence, few have distinguished between intentional and unintentional non-adherence. The present study attempted to identify factors associated with adherence, intentional non-adherence, and unintentional non-adherence among HIV+ individuals using a longitudinal design. Dietary instructions and medication schedule were also included to measure the subtleties of antiretroviral adherence. One hundred and two HIV+ patients who were under antiretroviral therapy were recruited in an outpatient clinic in Hong Kong at baseline with six months follow-up. Using the conventional adherence rate, only 12 (11.8%) of participants reported having missed/ altered medication in the past four days. However, using a more comprehensive assessment, only 27 (26.5%) participants were classified as adherers. Results showed that, adherers were significantly older and had higher adherence self-efficacy than those who were unintentional or intentional non-adherers. Participants classified as unintentional non-adherers had longer length of diagnosis and started medication longer than adherers and intentional non-adherers. Participants classified as intentional non-adherers had worse mental health, higher level of self-stigma, and reported higher score in avoidant coping than adherers and unintentional non-adherers. They also scored higher in physical symptoms than adherers. Findings highlight the importance of a reliable, comprehensive measurement for adherence and extend on previous adherence literature that intentional and unintentional non-adherence are separate entities and are associated with different factors. Future research should understand the intentions behind non-adherence and this would serve as an important guide in the development of interventions aimed at improving antiretroviral adherence for HIV+ patients.

Overload: impact of incident stressful events on antiretroviral medication adherence and virologic failure in a longitudinal, multisite human immunodeficiency virus cohort study

OBJECTIVE

To examine the influence of incident stressful experiences on antiretroviral medication adherence and treatment outcomes. Past trauma history predicts poorer medication adherence and health outcomes. Human immunodeficiency virus (HIV)-infected individuals experience frequently traumatic and stressful events, such as sexual and physical assault, housing instability, and major financial, employment, and legal difficulties.

METHODS

We measured prospectively incident stressful and traumatic events, medication adherence, and viral load over 27 months in an eight-site, five-state study. Using multivariable logistic and generalized estimating equation modeling, we assessed the impact of incident stressful events on 27-month changes in self-reported medication adherence and virologic failure (viral load = >or=400 c/mL).

RESULTS

Of 474 participants on antiretroviral therapy at baseline, 289 persons were interviewed and still received treatment at 27 months. Participants experiencing the median number of incident stressful events (n = 9) had over twice the predicted odds (odds ratio = 2.32) of antiretroviral medication nonadherence at follow-up compared with those with no events. Stressful events also predicted increased odds of virologic failure during follow-up (odds ratio = 1.09 per event).

CONCLUSIONS

Incident stressful events are exceedingly common in the lives of HIV-infected individuals and negatively affect antiretroviral medication adherence and treatment outcomes. Interventions to address stress and trauma are needed to improve HIV outcomes.

Adherence to Antiretroviral Therapy in the Context of the National Roll-Out in South Africa: Defining a Research Agenda for Psychology

Since 2004, antiretroviral therapy (ART) has been provided by the South African Department of Health to patients who need it as part of the national ART roll-out. Despite the initial success of a trial ART programme in Khayelitsha near Cape Town, it is unclear that adherence to ART is optimal among the patients receiving treatment in the context of the national roll-out. In this article I call attention to the psychosocial barriers to adherence that may potentially be faced by patients receiving ART. These barriers include poverty, health literacy, perceived social support, mental health, substance abuse, and stigma. Three social cognitive theories are briefly reviewed to conceptualise the phenomenon of ART adherence, namely, the Health Belief Model, the Theory of Planned Behaviour, and the Informational—Behavioural—Motivational Model. Constructs such as health motivation, perceived threats, perceived barriers, attitudes towards ART, perceived subjective norms, and perceived behavioural control are examined for their potential role in developing a theoretical understanding of adherence to ART. Finally, the role of culture is considered in response to concerns that social cognitive models developed in industrially developed countries are limited in their application in a developing country such as South Africa. As the question of adherence to ART in South Africa has received little attention from social science researchers, I set a tentative agenda for psychosocial research with a view to enhancing the likelihood of optimal adherence among AIDS patients.

HIV/AIDS-Specific Quality of Life and Adherence to Antiretroviral Therapy Over Time

OBJECTIVE

To determine if HIV/AIDS-specific quality of life (QOL) predicts adherence to antiretroviral therapy (ART).

METHODS

HIV-infected outpatients on efavirenz plus 2 or 3 nucleoside analogue reverse transcriptase inhibitors and with HIV viral loads <75 copies/mL were followed until the censoring event of detectable viremia or 1 year of follow-up. QOL was assessed at baseline with the HIV/AIDS-Targeted Quality of Life instrument (HAT-QoL), as were depression symptoms, stress levels, social support, and substance use. Follow-up high (> or =95%) versus low (<95%) adherence was measured for 90 days before the censoring event.

RESULTS

Fifty-six (48%) of 116 recruited participants had low adherence. Baseline financial worries (from the HAT-QoL) were greater in those with low versus high adherence (P = 0.02). Those with low versus high adherence also were more likely to use alcohol (P = 0.01) and other drugs (P = 0.02) currently at baseline. Regression analysis led to a model that included only current alcohol use (odds ratio [OR] = 2.65, 95% confidence interval [CI]: 1.20 to 5.87)) and financial worries (OR = 1.16, 95% CI: 1.03 to 1.310, for each 10-unit rise).

CONCLUSIONS

Baseline financial worries were associated with antiretroviral adherence later in time. Questions about paying bills and financial ability to care for oneself may be clinically useful in identifying patients who will have suboptimal adherence.

Factors associated with suboptimal antiretroviral therapy adherence to dose, schedule, and dietary instructions

The purpose of this study was to assess the degree of suboptimal antiretroviral therapy adherence to dose, schedule, and dietary instructions and to examine the effects of extra-personal, intra-personal, and inter-personal factors on suboptimal adherence across the three types of instructions. Self-report and clinical data were collected from 193 sexually infected Swedish patients receiving ART. Effects of extra-personal, intra-personal, and inter-personal factors on suboptimal adherence were examined using multivariate logistic regression models. Suboptimal adherence to dose instructions was recorded in 12% of patients. Equivalent percentage for suboptimal adherence to schedule instructions was 37% and for suboptimal adherence to dietary instructions 58%. Anxiety was the only risk factor for suboptimal adherence to dose. Heavy pill burden was a risk factor for suboptimal adherence to schedule. Older age and HIV-related post-traumatic stress disorder (PTSD) symptoms decreased the risk of suboptimal adherence to schedule. No factors investigated had an effect on suboptimal adherence to dietary instructions. To improve adherence to dose and schedule instructions, clinicians caring for patients with HIV should assess and treat anxiety and be alert to HIV-related PTSD symptoms.
