Does Economic Strengthening Improve Viral Suppression Among Adolescents Living with HIV? Results From a Cluster Randomized Trial in Uganda

Low HIV Viral Load Suppression and Its Implications for Controlling HIV among Refugee Adolescents and Youth Living in Refugee Settlements in Uganda: A Cross-sectional Analysis

Viral load suppression (VLS) is considered crucial in the global efforts to end the HIV/AIDS pandemic and young people lag behind adults in this important indicator. However, little is known about VLS among refugee adolescents and youth (RAY), a vulnerable group, often ignored by research, with multiple intersecting risk factors and unique challenges. The goal of this study was to determine the prevalence of VLS and examine associated risk and protective factors among RAY in refugee settlements in Uganda, a country severely affected by the HIV/AIDS pandemic and currently hosting the most refugees in sub-Saharan Africa (SSA). We analyzed cross-sectional data from a pilot cluster randomized trial with 180 participants (ages 13-30) recruited from 20 health centers in three refugee settlements between July and December 2023. We employed a hierarchical (mixed-effects) logistic regression model to examine the association between selected demographic, psychosocial, and economic factors and VLS. The prevalence of VLS among RAY was very low at just 52%. Factors associated with VLS included financial stability, adherence self-efficacy, and HIV status disclosure. Having financial savings was associated with VLS (adjusted odds ratio:2.68; 95% CI: 1.48-5.11; p = 0.003). Treatment support from others including teachers and health care providers had five-fold odds of VLS (5.0, 1.64-15.24; p = 0.005). Conversely, older age and interactions between stigma/self-efficacy and stigma/HIV status disclosure were associated with viral load non-suppression. This study highlights the urgent need for tailored interventions targeting economic and psychosocial hardships like poverty, stigma, and food insecurity to enhance HIV VLS and other treatment outcomes among RAY.

Mlambe economic and relationship-strengthening intervention for alcohol use decreases violence and improves relationship quality in couples living with HIV in Malawi

INTRODUCTION

A syndemic of unhealthy alcohol use, intimate partner violence (IPV), and economic insecurity threatens to derail progress towards UNAIDS 95-95-95 targets in sub-Saharan Africa. We developed a combined economic and relationship-strengthening intervention called Mlambe to reduce unhealthy alcohol use and increase adherence to antiretroviral therapy for couples in Malawi. This study evaluates the additional impact of Mlambe on IPV and relationship dynamics.

METHODS

In a pilot randomized controlled trial, 78 married couples (156 individuals) living with HIV and reporting unhealthy alcohol use based on the AUDIT-C (at least one partner) were recruited from HIV care clinics in Zomba, Malawi. The intervention arm (39 couples) received a 10-month program consisting of incentivized savings accounts with financial literacy education, relationship education, and couples counseling sessions to build relationship skills. The control arm (39 couples) received enhanced usual care (EUC) with brief alcohol counseling. We used linear mixed-effects models to assess the effects of Mlambe on relationship quality (e.g., constructive communication, unity, sexual satisfaction) and IPV (physical, sexual, and emotional) by including fixed effects for treatment arm and a random effect for dyad, and tested whether effects on IPV and relationship quality differed by gender.

RESULTS

At 10- and 15-month follow-up visits, couples in the Mlambe arm showed greater increases in couple communication, unity, sexual satisfaction, intimacy, and trust (Cohen's d ranged from 0.36 to 0.56; p < 0.05) as compared to EUC. Couples in the Mlambe arm also showed significant decreases in physical and emotional IPV (Cohen's d ranged from 0.33 to 0.49; p < 0.05) as compared to EUC. Subsequent moderation analyses indicated that women reported significantly greater improvements in relationship quality than men, except for sexual satisfaction (p < 0.05), and greater declines in physical IPV than men (p < 0.05).

CONCLUSIONS

Mlambe resulted in significant improvements in relationship quality and decreased IPV in couples, particularly for women who as a group reported lower relationship quality at baseline. Economic and relationship-strengthening interventions have potential to disrupt harmful syndemics of violence, substance use, and poverty among couples living with HIV.

In Utero Mother-to-Child Transmission of HIV-1 and the Associated Factors in Rwanda, Africa

Mother-to-child transmission (MTCT) of HIV-1 and associated mortality continue to occur at unacceptably high rates, despite the extensive rollout and implementation of Prevention of Mother-to-Child Transmission (PMTCT) Programs, including the modified versions of Option B and B+ in 2010 and 2012, respectively. Maternal HIV viral load (VL) and socio-behavioral factors sustaining MTCT in Rwanda remain largely unexplored. The study examined the effects of socio-behavioral factors on maternal VL and their contribution to in utero transmission of HIV-1 in the context of Rwanda's HIV epidemic. A prospective cohort study was conducted in 862 mother-baby pairs enrolled in 10 PMTCT clinics in Rwanda. VL was determined on plasma and Dried Blood Spots samples, whereas HIV DNA PCR was performed to determine in utero MTCT of HIV of the babies immediately at birth and then at 3 weeks, 4 weeks, 6 months, and 18 months, together with HIV antibody testing to determine other forms of MTCT of HIV. Quantitative data on socio-behavioral factors were collected through a structured questionnaire. Linear regression and univariate analysis of variances using SPSS 25.0 were used to test the hypotheses. We found 22/862 (2.55%) cases of in utero transmission and a total of 32/862 (3.7%) cases of MTCT of HIV-1 over 18 study months. Maternal VL at delivery was significantly associated with the risk of in utero transmission of HIV-1. Socio-behavioral factors associated with elevated maternal VL at delivery included alcohol, smoking, multiple sexual partners, mothers' income, being a casual laborer, and distance to health care services. We report an MTCT rate of 3.7% in our study population over the 18 months, higher than the national average of 1.5%, the majority of which occurred in utero. MTCT cases were attributable to failure to suppress maternal VL.

Pilot Trial Results of Mlambe: An Economic and Relationship-Strengthening Intervention to Address Heavy Drinking and Adherence to Antiretroviral Therapy in Malawi

We evaluated the feasibility, acceptability, and preliminary efficacy of an economic and relationship-strengthening intervention to reduce heavy alcohol use among couples living with HIV in Malawi (Mlambe). Mlambe consisted of training on financial literacy and relationship skills, combined with 1:1 matched savings accounts to invest in an income-generating activity. In a randomized controlled trial, we compared Mlambe to enhanced usual care (EUC). We enrolled 78 married couples having a partner on antiretroviral therapy (ART) who reported heavy alcohol use based on the AUDIT-C. Using targets of 75%, primary outcomes included retention rates at 10 and 15-months, session attendance rates, and satisfaction with Mlambe. Exploratory outcomes were heavy alcohol use (AUDIT-C and/or PEth positive), number of drinking days in the past month, AUDIT-C score, optimal adherence to ART (95% or higher), and viral suppression. We exceeded our targets for feasibility and acceptability metrics. Retention rates were 96% at 15-months. Session attendance and satisfaction levels were both 100%. From baseline to 15-months, Mlambe participants reported decreases in mean number of drinking days (from 6.8 to 2.1) and AUDIT-C scores (from 7.5 to 3.1); while ART adherence rates improved across the same period (from 63.2 to 73.9%). Participants in Mlambe, as compared to those in EUC, had lower rates of heavy alcohol use (89.5% vs. 97.2%) and higher rates of viral suppression (100% vs. 91.9%) at 10-months. Differences between arms were not statistically significant in this small pilot study. Mlambe was highly feasible and acceptable, and shows promise for reducing heavy alcohol use and viral non-suppression among couples with HIV in a larger efficacy study.

A qualitative analysis of self-management needs of adolescents and young adults living with perinatally acquired HIV in rural, southwestern Uganda

The number of adolescents living with HIV remains high in sub-Saharan Africa with poorer HIV treatment outcomes among adolescents and young adults compared to individuals in other age groups. For adolescents and young adults living with perinatally acquired HIV (AYLPHIV), the transition from pediatric to adult HIV care is a particularly high-risk period. We conducted a qualitative study to understand self-management needs of AYLPHIV in rural, southwestern Uganda as they prepare to transition to adult HIV care in order to inform relevant interventions that can enable AYLPHIV acquire the necessary skills to manage their illness as they age into adulthood. We conducted 60 in-depth interviews with AYLPHIV (n = 30), caregivers (n = 20) and health care providers (n = 10) from the HIV clinic at Mbarara Regional Referral Hospital. We used an interview guide that focused on perceptions about transition to adult HIV care, challenges with transitioning, navigating HIV care, and self-management needs for AYLPHIV (from the perspectives of AYLPHIV, their caregivers, and health care providers). We used thematic analysis to identify themes related to AYLPHIV's self-management skills. We identified several self-management needs that we grouped under two major themes; social support and empowerment for AYLPHIV to assume responsibility for their own health and to navigate adult HIV care independently. The sub-themes under social support were information support, instrumental support, and emotional support as the sub themes while sub-themes under empowerment included self-advocacy skills, interpersonal skills, self-care skills, and disclosure skills. Taken together, these findings indicate that AYLPHIV need to be supported and empowered to maximize their chances of successfully transitioning to adult HIV care. Support comes from peers and caregivers. AYLPHIV require knowledge about their HIV status and empowerment with different skills including: self-advocacy skills, interpersonal skills, self-care skills, and HIV status disclosure skills, in order to assume responsibilities related to independent HIV care.

Effects of economic interventions on pediatric and adolescent HIV care outcomes: a systematic review

Economic insecurity and poverty present major barriers to HIV care for young people. We conducted a systematic review of the current evidence for the effect of economic interventions on HIV care outcomes among pediatric populations encompassing young children, adolescents, and youth (ages 0-24). We conducted a search of PubMed MEDLINE, Cochrane, Embase, Scopus, CINAHL, and Global Health databases on October 12, 2022 using a search strategy curated by a medical librarian. Studies included economic interventions targeting participants <25 years in age which measured clinical HIV outcomes. Study characteristics, care outcomes, and quality were independently assessed, and findings were synthesized. Title/abstract screening was performed for 1934 unique records. Thirteen studies met inclusion criteria, reporting on nine distinct interventions. Economic interventions included incentives (n = 5), savings and lending programs (n = 3), and government cash transfers (n = 1). Study designs included three randomized controlled trials, an observational cohort study, a matched retrospective cohort study, and pilot intervention studies. While evidence is very limited, some promising findings were observed supporting retention and viral suppression, particularly for those with suboptimal care engagement or with detectable viral load. There is a need to further study and optimize economic interventions for children and adolescents living with HIV.

Interventions to Improve Adolescent HIV Care Outcomes

PURPOSE OF REVIEW

This review of recent studies evaluating interventions to improve HIV care outcomes among adolescents with HIV (AHIV) was conducted to provide a comprehensive overview of the recent evidence, highlight promising approaches, and suggest directions for future research.

RECENT FINDINGS

Our scoping review revealed 65 studies evaluating a variety of interventions and using a range of study designs at various stages of research. Effective approaches included community-based, integrated service delivery models with case management, trained community adolescent treatment supporters, and consideration of social determinants of health. Recent evidence also supports the feasibility, acceptability, and preliminary efficacy of other innovative approaches, including mental health interventions as well as technology-delivered approaches; however, more research is needed to build the evidence base for these interventions. Our review's findings suggest that interventions providing comprehensive, individualized support are essential to improving HIV care outcomes among adolescents. More research is needed to build the evidence base for such interventions and ensure effective, equitable implementation to support the global target of ending the AIDS epidemic by 2030.

The relationship between life satisfaction, personal health, quality of life, and medication adherence among adolescents living with HIV in southwestern Uganda

Purpose

Adolescents living with HIV (ALHIV) are at high risk for adherence to antiretroviral (ART) treatment and poor health-seeking behaviors, both of which potentially compromise their quality of and satisfaction with life. This study, therefore, seeks to examine the relationship between physical health, pediatric quality of life, life satisfaction, and medication adherence among ALHIV in southwestern Uganda.

Methods

Baseline data from the Suubi+Adherence study, 2012-2018, that recruited 702 adolescents, aged 10-16 years, living with HIV in Uganda were analyzed. To account for overdispersion, negative binomial regression analyses were used to examine the impact of physical health, pediatric quality of life, and life satisfaction on self-reported medication adherence. We controlled for participants' socio-demographic factors.

Results

Results indicated that after adjusting for socio-demographic characteristics, adolescents' reported satisfaction with life was associated with a decrease in the reported number of days missed taking medication by 41.2% (IRR (incidence risk ratio)=0.588; p (p-value)=0.014). On the other hand, the low level of pediatric quality of life was associated with a 5% increase in the reported number of days missed taking medication (IRR=1.055, p=0.044). Personal health was not statistically significant in the model.

Conclusion

Our study findings indicated that quality of life and life satisfaction are significantly associated with antiretroviral (ART) medication among ALHIV. Hence, strengthening existing support systems and creating additional support for optimal ART adherence and treatment outcomes for ALHIV in low-resource communities might be beneficial. Moreover, with the increasing HIV prevalence rates among adolescents, effective and comprehensive efforts that are responsive to the special needs of ALHIV must be developed to ensure optimal adherence to ART medication as it leads to low vertical infection and superinfection rates.

Development of an Economic and Relationship-Strengthening Intervention for Alcohol Drinkers Living with HIV in Malawi

Heavy alcohol use among people with HIV in sub-Saharan Africa is driven by household economics such as poverty and unemployment and has negative impacts on couple relationships. Multilevel interventions have the potential to reduce alcohol use and improve relationship outcomes by addressing the web of co-occurring economic, social, and dyadic factors. This objective of this study was to develop an economic and relationship-strengthening intervention for couples in Malawi, consisting of matched savings accounts with financial literacy training and a couples counseling component to build relationship skills. Informed by the ADAPT-ITT framework, we collected multiple rounds of focus group data with key stakeholders and couples to gain input on the concept, session content, and procedures, held team meetings with field staff and an international team of researchers to tailor the intervention to couples in Malawi, and refined the intervention manual and components. The results describe a rigorous adaptation process based on the eight steps of ADAPT-ITT, insights gained from formative data and modifications made, and a description of the final intervention to be evaluated in a pilot randomized clinical trial. The economic and relationship-strengthening intervention shows great promise of being feasible, acceptable, and efficacious for couples affected by HIV and heavy alcohol use in Malawi.

Development and validation of a prediction tool to support engagement in HIV care among young people ages 10-24 years in Kenya

INTRODUCTION

Loss to follow-up (LTFU) among adolescents and young adults living with HIV (AYALWH) is a barrier to optimal health and HIV services. We developed and validated a clinical prediction tool to identify AYALWH at risk of LTFU.

METHODS

We used electronic medical records (EMR) of AYALWH ages 10 to 24 in HIV care at 6 facilities in Kenya and surveys from a subset of participants. Early LTFU was defined as >30 days late for a scheduled visit in the last 6 months, which accounts for clients with multi-month refills. We developed a tool combining surveys with EMR ('survey-plus-EMR tool'), and an 'EMR-alone' tool to predict high, medium, and low risk of LTFU. The survey-plus-EMR tool included candidate sociodemographics, partnership status, mental health, peer support, any unmet clinic needs, WHO stage, and time in care variables for tool development, while the EMR-alone included clinical and time in care variables only. Tools were developed in a 50% random sample of the data and internally validated using 10-fold cross-validation of the full sample. Tool performance was evaluated using Hazard Ratios (HR), 95% Confidence Intervals (CI), and area under the curve (AUC) ≥ 0.7 for good performance and ≥0.60 for modest performance.

RESULTS

Data from 865 AYALWH were included in the survey-plus-EMR tool and early LTFU was (19.2%, 166/865). The survey-plus-EMR tool ranged from 0 to 4, including PHQ-9 ≥5, lack of peer support group attendance, and any unmet clinical need. High (3 or 4) and medium (2) prediction scores were associated with greater risk of LTFU (high, 29.0%, HR 2.16, 95%CI: 1.25-3.73; medium, 21.4%, HR 1.52, 95%CI: 0.93-2.49, global p-value = 0.02) in the validation dataset. The 10-fold cross validation AUC was 0.66 (95%CI: 0.63-0.72). Data from 2,696 AYALWH were included in the EMR-alone tool and early LTFU was 28.6% (770/2,696). In the validation dataset, high (score = 2, LTFU = 38.5%, HR 2.40, 95%CI: 1.17-4.96) and medium scores (1, 29.6%, HR 1.65, 95%CI: 1.00-2.72) predicted significantly higher LTFU than low-risk scores (0, 22.0%, global p-value = 0.03). Ten-fold cross-validation AUC was 0.61 (95%CI: 0.59-0.64).

CONCLUSIONS

Clinical prediction of LTFU was modest using the surveys-plus-EMR tool and the EMR-alone tool, suggesting limited use in routine care. However, findings may inform future prediction tools and intervention targets to reduce LTFU among AYALWH.

Development of "Yima Nkqo," a community-based, peer group intervention to support treatment initiation for young adults with HIV in South Africa

AIMS

Half of young adults diagnosed with HIV in South Africa start antiretroviral therapy (ART). We developed and field tested a facilitator-guided peer support group called Yima Nkqo ("Standing Tall" in isiXhosa) to promote treatment initiation for young adults newly diagnosed with HIV in communities around Cape Town.

METHODS

Following an adapted version of the UK Medical Research Council's framework for developing complex interventions, we 1) identified evidence on previous interventions to improve ART uptake in sub-Saharan Africa; 2) collected and analyzed qualitative data on the acceptability of our proposed intervention; 3) proposed a theoretical understanding of the process of behavior change; and 4) developed an intervention manual and feedback tools. During field-testing, participant feedback on intervention acceptability, and team feedback on consistency of content delivery and facilitation quality, were analyzed using an iterative, rapid-feedback evaluation approach. In-depth written and verbal summaries were shared in weekly team meetings. Team members interpreted feedback, identified areas for improvement, and proposed suggestions for intervention modifications.

RESULTS

Based on our formative research, we developed three, 90-minute sessions with content including HIV and ART education, reflection on personal resources and strengths, practice disclosing one's status, strategies to overcome stressors, and goal setting to start treatment. A lay facilitator was trained to deliver intervention content. Two field testing groups (five and four participants, respectively) completed the intervention. Participants highlighted that strengths of Yima Nkqo included peer support, motivation, and education about HIV and ART. Team feedback to the facilitator ensured optimal consistency of intervention content delivery.

CONCLUSIONS

Iteratively developed in collaboration with youth and healthcare providers, Yima Nkqo is a promising new intervention to improve treatment uptake among young adults with HIV in South Africa. The next phase will be a pilot randomized controlled trial of Yima Nkqo (ClinicalTrials.gov Identifier: NCT04568460).

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.

The effect of family support on self-reported adherence to ART among adolescents perinatally infected with HIV in Uganda: A mediation analysis

INTRODUCTION

This study examined the mechanisms through which family support affects self-reported adherence to antiretroviral therapy among adolescents perinatally infected with HIV in Uganda.

METHODS

Longitudinal data from 702 adolescent boys and girls (10-16 years) were analyzed. Structural equation models were conducted to assess the direct, indirect, and total effects of family support on adherence.

RESULTS

Results showed a significant indirect effect of family support on adherence (β = .112, 95% confidence interval [CI]: 0.052-0.173, p < .001). Specific indirect effects of family support through saving attitudes (β = .058, 95% CI: 0.008-0.108, p = .024), and communication with the guardian (β = .056, 95% CI: 0.012-0.100), p = .013), as well as the total effect of family support on adherence (β = .146 (95% CI: 0.032-0.259, p = .012), were statistically significant. Mediation contributed 76.7% of the total effects.

CONCLUSION

Findings support strategies to help promote family support and strengthen open communication between adolescents living with HIV and their caregivers.

A Structural Equation Model of the Impact of a Family-Based Economic Intervention on Antiretroviral Therapy Adherence Among Adolescents Living With HIV in Uganda

PURPOSE

Antiretroviral therapy (ART) adherence among adolescents living with HIV (ALWHIV) is low, with poverty remaining a significant contributor. We examined the mediation pathways between an economic empowerment intervention and ART adherence among ALWHIV.

METHODS

This cluster-randomized controlled trial (2012-2018) recruited 702 ALWHIV aged 10-16 in Uganda between January 2014 and December 2015. We randomized 39 clinics into the control (n = 344) or intervention group (n = 358). The intervention comprised a child development account, four microenterprise workshops, and 12 mentorship sessions. We used six self-reported items to measure adherence at 24 months, 36 months, and 48 months. We used structural equation modeling to assess the mediation effects through mental health and adherence self-efficacy, on adherence. We ran models corresponding to the 24, 36, and 48 months of follow-up.

RESULTS

The mean age of the participants was 12 years, and 56% were female. At 36 (model 2) and 48 months (model 3), the intervention had a significant indirect effect on ART adherence [B = 0.069, β = 0.039 (95% confidence interval [CI]: 0.005-0.074)], and [B = 0.068, β = 0.040 (95% CI: 0.010-0.116)], respectively. In both models, there was a specific mediation effect through mental health [B = 0.070, β = 0.040 (95% CI: 0.007-0.063)], and [B = 0.039, β = 0.040 (95% CI: 0.020-0.117)]. Overall, 49.1%, 90.7%, and 36.8% of the total effects were mediated in models, 1, 2, and 3, respectively.

DISCUSSION

EE interventions improve adherence, by improving mental health functioning. These findings warrant the need to incorporate components that address mental health challenges in programs targeting poverty to improve ART adherence in low-income settings.

Suubi + Adherence4Youth: a study protocol to optimize the Suubi Intervention for Adherence to HIV treatment for youth living with HIV in Uganda

BACKGROUND

Suubi is an evidenced based multi-component intervention that targets psychosocial and economic hardships to improve ART adherence, viral suppression, mental health, family financial stability, and family cohesion for adolescents living with HIV (ALHIV) in Uganda. Suubi was originally tested as a combined package of four components: 1) Financial Literacy Training; 2) incentivized matched Youth Savings Accounts with income-generating activities; 3) a manualized and visual-based intervention for ART adherence and stigma reduction; and 4) engagement with HIV treatment-experienced role models. However, it is unknown if each component in Suubi had a positive effect, how the components interacted, or if fewer components could have produced equivalent effects. Hence, the overall goal of this new study is to identify the most impactful and sustainable economic and psychosocial components across 48 health clinics in Uganda.

METHODS

A total of 576 ALHIV (aged 11-17 years at enrollment) will be recruited from 48 clinics and each clinic will be randomized to one of 16 study conditions. Each condition represents every possible combination of the 4 components noted above. Assessments will be conducted at baseline, 12, 24, 36 and 48- months post-intervention initiation. Using the multi-phase optimization strategy (MOST), we will identify the optimal combination of components and associated costs for viral suppression, as well as test key mediators and moderators of the component-viral suppression relationship.

DISCUSSION

The study is a shift in the paradigm of research to use new thinking to build/un-pack highly efficacious interventions that lead to new scientific knowledge in terms of understanding what drives an intervention's success and how to iterate on them in ways that are more efficient, affordable and scalable. The study advances intervention science for HIV care outcomes globally.

The effect of group support psychotherapy on adherence to anti-retroviral therapy and viral suppression among HIV positive young people: Study protocol for a pilot randomized controlled trial

Background

Several studies have demonstrated an association between psychological risk factors and HIV disease progression. However, there is limited information on the use of psychological interventions to improve HIV treatment outcomes in young people living with HIV.

Objective

This pilot trial aims to evaluate the feasibility, acceptability and preliminary effectiveness of group support psychotherapy in improving adherence to anti-retroviral therapy and viral suppression in young people living with HIV in Uganda.

Methods

We recruited 120 young people with HIV, aged 10–18 years, who had non-viral suppression 6 months after initiating first-line anti-retroviral therapy (ART) from community based HIV clinics in Kitgum district, northern Uganda. Participants were randomly assigned to receive GSP plus IAC (N = 60) or IAC alone (N = 60). Primary outcomes will be indicators of feasibility and acceptability as well as preliminary effectiveness of GSP in improving ART adherence and viral suppression analysed by intention to treat using cluster-adjusted t tests and permutation tests. Secondary outcomes will be measures of depression, anxiety and cost-effectiveness.

Results

The trial has been approved by the Makerere College of Health Sciences School of Health Sciences Research Ethics Committee, and the Uganda National Council of Science and Technology. Recruitment began in June 2021 and 120 young people living with HIV with their adult caregivers have been recruited to the trial. An analysis of baseline and 6-month data is in progress. The results of this trial will not only be presented at national and international conferences but also submitted for publication in peer-reviewed journals and as a report to the funding agencies.

Conclusions

This pilot trial will provide critical evidence to support the ongoing mental health integration into routine HIV care in Uganda.

The Impact of an Economic Strengthening Intervention on Academic Achievement Among Adolescents Living with HIV: Findings from the Suubi + Adherence Cluster-Randomized Trial in Uganda (2012-2018)

We examined the impact of a family-based economic strengthening intervention on school dropout and repeating a class among ALWHIV in Uganda. In this cluster-randomized trial (2012-2018) conducted in 39 clinics, we recruited adolescents aged 10-16 years living with HIV. We included data from 613 adolescents. We plotted a Kaplan Meier survival curve and fitted Cox proportional hazards models to test the effect of the economic strengthening intervention on school dropout. The incidence of school dropout was 13.0% and 9.6% in the control and intervention groups, respectively. Also, economic empowerment reduced the risk of school dropout, aHR = 0.68 (95% CI 0.52-0.88), p-value 0.004. In other words, participants in the intervention group had 32% reduced hazards of dropping out of school. Also, increasing age aHR = 1.54 (95% CI 1.42-1.66), p-value < 0.001 and double orphanhood aHR = 0.67 (95% CI 0.47-0.96) p-value 0.030 increased the risks for dropping out of school. The intervention was not efficacious in reducing the rates of repeating a class. The intervention offered the ALWHIV an opportunity to live a productive adult life. More research is required on these kinds of interventions intended to keep ALWHIV and those impacted by HIV in school.

Barriers and facilitators to anti-retroviral therapy adherence among adolescents aged 10 to 19 years living with HIV in sub-Saharan Africa: A mixed-methods systematic review and meta-analysis

BACKGROUND

Human Immunodeficiency Virus (HIV) significantly affects adolescents globally, with the sub-Saharan Africa (SSA) reporting a high burden of the disease. HIV testing, treatment, and retention to care are low among adolescents. We conducted a mixed-method systematic review to assess anti-retroviral therapy (ART) adherence; barriers and facilitators to ART adherence and ART outcomes among adolescents living with HIV and on ART in sub-Saharan Africa.

METHODS

We conducted searches in four scientific databases for studies conducted between 2010 and March 2022 to identify relevant primary studies. Studies were screened against inclusion criteria and assessed for quality, and data was extracted. Meta-analysis of rates and odd ratios was used to plot the quantitative studies and meta-synthesis summarized the evidence from qualitative studies.

RESULTS

A total of 10 431 studies were identified and screened against the inclusion/ exclusion criteria. Sixty-six studies met the inclusion criteria (41 quantitative, 16 qualitative, and 9 mixed-methods study designs). Fifty-three thousand two hundred and seventeen (53 217) adolescents (52 319 in quantitative studies and 899 in qualitative studies) were included in the review. Thirteen support focused interventions for improved ART adherence were identified from quantitative studies. The plotted results from the meta-analysis found an ART adherence rate of 65% (95%CI 56-74), viral load suppression was 55% (95%CI 46-64), un-suppressed viral load rate of 41% (95%CI 32-50), and loss to follow up of 17% (95%CI 10-24) among adolescents. Meta-synthesis found six themes of barriers to ART (social, patient-based, economic, health system-based, therapy-based, and cultural barriers) in both the qualitative and quantitative studies, and three themes of facilitators to ART were also identified (social support, counselling, and ART education and secrecy or confidentiality) from qualitative studies.

CONCLUSION

ART adherence remains low among adolescents in SSA despite multiple interventions implemented to improve ART adherence. The low adherence rate may hinder the attainment of the UNAIDS 2030 targets. Additionally, various barriers to ART adherence due to lack of support have been reported among this age group. However, interventions aimed at improving social support, educating, and counselling adolescents may improve and sustain ART adherence.

Effectiveness of a peer educator-coordinated preference-based differentiated service delivery model on viral suppression among young people living with HIV in Lesotho: The PEBRA cluster-randomized trial

BACKGROUND

Southern and Eastern Africa is home to more than 2.1 million young people aged 15 to 24 years living with HIV. As compared with other age groups, this population group has poorer outcomes along the HIV care cascade. Young people living with HIV and the research team co-created the PEBRA (Peer Educator-Based Refill of ART) care model. In PEBRA, a peer educator (PE) delivered services as per regularly assessed patient preferences for medication pick-up, short message service (SMS) notifications, and psychosocial support. The cluster-randomized trial compared PEBRA model versus standard clinic care (no PE and ART refill done by nurses) in 3 districts in Lesotho.

METHODS AND FINDINGS

Individuals taking antiretroviral therapy (ART) aged 15 to 24 years at 20 clinics (clusters) were eligible. In the 10 clinics randomized to the intervention arm, participants were offered the PEBRA model, coordinated by a trained PE and supported by an eHealth application (PEBRApp). In the 10 control clusters, participants received standard nurse-coordinated care without any service coordination by a PE. The primary endpoint was 12-month viral suppression below 20 copies/mL. Analyses were intention-to-treat and adjusted for sex. From November 6, 2019 to February 4, 2020, we enrolled 307 individuals (150 intervention, 157 control; 218 [71%] female, median age 19 years [interquartile range, IQR, 17 to 22]). At 12 months, 99 of 150 (66%) participants in the intervention versus 95 of 157 (61%) participants in the control arm had viral suppression (adjusted odds ratio (OR) 1.27; 95% confidence interval [CI] [0.79 to 2.03]; p = 0.327); 4 of 150 (2.7%) versus 1 of 157 (0.6%) had died (adjusted OR 4.12; 95% CI [0.45 to 37.62]; p = 0.210); and 12 of 150 (8%) versus 23 of 157 (14.7%) had transferred out (adjusted OR 0.53; 95% CI [0.25 to 1.13]; p = 0.099). There were no significant differences between arms in other secondary outcomes. Twenty participants (11 in intervention and 9 in control) were lost to follow-up over the entire study period. The main limitation was that the data collectors in the control clusters were also young peers; however, they used a restricted version of the PEBRApp to collect data and thus were not able to provide the PEBRA model. The trial was prospectively registered on ClinicalTrials.gov (NCT03969030).

CONCLUSIONS

Preference-based peer-coordinated care for young people living with HIV, compared to nurse-based care only, did not lead to conclusive evidence for an effect on viral suppression.

Economic Well-being and Associated Mediating Pathways to Improved Antiretroviral Therapy Adherence Among Adolescents Living With HIV: A Prospective Cohort Study in South Africa

BACKGROUND

Adolescents living with HIV exhibit lower levels of adherence to antiretroviral therapy (ART) than other age groups. Poverty is a key barrier to ART adherence. This study aims at understanding how alleviating poverty through structural and internal pathways can help increase ART adherence among adolescents.

SETTING

Eastern Cape province, South Africa.

METHODS

One thousand forty-six adolescents living with HIV were recruited from 53 public health care facilities and interviewed at 3 data collection waves with a retention rate of 89% and a mortality rate of 3%. Data were collected by face-to-face, device-assisted interviews. Hybrid probit regressions and a structural equation path analysis were used to estimate the association between poverty reduction (increased access to basic necessities) and the pathways by which it could improve ART adherence.

RESULTS

Self-reported ART adherence ranged from an average of 66% (n = 615) at baseline to 75% (n = 700) in the last wave. Within-person and between-person improvements in economic well-being were associated with significant increases in adolescent ART adherence. On average, adolescents with access to 3 additional basic needs experienced a 4 percentage-point increase in the probability of ART adherence. Structural pathways to improved ART adherence included participants having enough money to travel to the clinic and sufficient food to eat when taking medication. Internal pathways included improved psychological well-being and reduced internalized HIV stigma.

CONCLUSION

Poverty reduction programs such as HIV-sensitive social protection can address structural and psychological pathways to increase ART adherence among economically disadvantaged adolescents by incentivizing demand-side interventions and the provision of quality essential services.

Rediscovering life after being diagnosed with HIV: A qualitative analysis of lived experiences of youth living with HIV in rural Rwanda

Introduction

In sub-Saharan Africa, youth living with HIV, especially those who have lost one or both parents, face economic, socially and psychological challenges that hinder adherence to ART, ultimately leading to poor health outcomes. Partners In Health/Inshuti Mu Buzima implemented an Adolescent Support Group (ASG) to support HIV-positive youth aged 15-25 years. During the evaluation of the ASG program, we sought to better understand youths' lived experiences to improve our delivery of HIV care.

Methods

We conducted qualitative in-depth, semi-structured individual interviews with youth enrolled in the ASG program. All interviews were conducted in-person or by telephone. Thematic analysis applying the framework approach with parallel inductive coding in Kinyarwanda and English was used.

Results

We interviewed 35 youth who ranged in age from 16 to 29 years. The main themes related to the lived experiences of youth were (a) Experiences living with HIV, including disclosure, stigma, interactions with the health care system, and medication adherence; (b) external challenges, defined as challenges that were not related to the implementation of the ASG program; and (c) personal vision. Almost all youth reported acquiring HIV from their mothers and disclosure of HIV status occurred around the age of 10. Disclosure was often unintentional and followed by internalized and enacted stigma. Many reported poor past medication adherence which improved following enhanced counselling. External challenges were overwhelmingly economic in nature, and orphanhood was a root cause of other challenges such as difficulty accessing education, lack of transport to health facility, and lack of insurance fees. Despite these challenges, youth have an optimistic view of the future with dreams of health, economic attainment, marriage, and children.

Conclusion

Healthcare providers should empower caregivers to support HIV disclosure. Supporting youth as they face many economic challenges could help address socio-economic barriers to good health and promote holistic well-being.

Impact of Family-Based Economic Empowerment Intervention, Suubi+Adherence (2012-2018) on Multidimensional Poverty for Adolescents Living with HIV (ALWHIV) in Uganda

Children growing up in poverty are disproportionately affected by diseases, including HIV. In this study, we use data from Suubi+Adherence, a longitudinal randomized control trial (2012-2018) with 702 adolescents living with HIV (ALWHIV), to examine the effectiveness of a family-based multifaceted economic empowerment (EE) intervention in addressing economic instability and multidimensional poverty among ALWHIV in Southern Uganda. We constructed a Multidimensional Poverty Index of individual and household indicators, including health, assets, housing and family dynamics. We computed the proportion of multidimensionally poor children (H), estimated poverty intensity (A) and adjusted headcount ratio (M₀). Using repeated measures at five-time points (baseline, years 1, 2, 3 and 4-post baseline) across two study arms: treatment (receiving the EE intervention) vs. control arm (not receiving EE), we find that both the incidence and proportion of multidimensional poverty decreased in the treatment arm vs. the control arm. Given that there is a direct link between economic instability and poor health outcomes, these findings are informative. They point to the potential for family EE interventions to decrease multidimensional poverty among vulnerable children, including ALWHIV, impacting their overall wellbeing and ability to meet their treatment needs and improve HIV care continuum outcomes.

A Multilevel Integrated Intervention to Reduce the Impact of HIV Stigma on HIV Treatment Outcomes Among Adolescents Living With HIV in Uganda: Protocol for a Randomized Controlled Trial

BACKGROUND

HIV stigma remains a formidable barrier to HIV treatment adherence among school-attending adolescents living with HIV, owing to high levels of HIV stigma within schools, rigid school structures and routines, lack of adherence support, and food insecurity. Thus, this protocol paper presents an evidence-informed multilevel intervention that will simultaneously address family- and school-related barriers to HIV treatment adherence and care engagement among adolescents living with HIV attending boarding schools in Uganda.

OBJECTIVE

The proposed intervention-Multilevel Suubi (MSuubi)-has the following objectives: examine the impact of M-Suubi on HIV viral suppression (primary outcome) and adherence to HIV treatment, including keeping appointments, pharmacy refills, pill counts, and retention in care; examine the effect of M-Suubi on HIV stigma (internalized, anticipated, and enacted), with secondary analyses to explore hypothesized mechanisms of change (eg, depression) and intervention mediation; assess the cost and cost-effectiveness of each intervention condition; and qualitatively examine participants' experiences with HIV stigma, HIV treatment adherence, and intervention and educators' attitudes toward adolescents living with HIV and experiences with group-based HIV stigma reduction for educators, and program or policy implementation after training.

METHODS

MSuubi is a 5-year multilevel mixed methods randomized controlled trial targeting adolescents living with HIV aged 10 to 17 years enrolled in a primary or secondary school with a boarding section. This longitudinal study will use a 3-arm cluster randomized design across 42 HIV clinics in southwestern Uganda. Participants will be randomized at the clinic level to 1 of the 3 study conditions (n=14 schools; n=280 students per study arm). These include the bolstered usual care (consisting of the literature on antiretroviral therapy adherence promotion and stigma reduction), multiple family groups for HIV stigma reduction plus family economic empowerment (MFG-HIVSR plus FEE), and Group-based HIV stigma reduction for educators (GED-HIVSR). Adolescents randomized to the GED-HIVSR treatment arm will also receive the MFG-HIVSR plus FEE treatment. MSuubi will be provided for 20 months, with assessments at baseline and 12, 24, and 36 months.

RESULTS

This study was funded in September 2021. Participant screening and recruitment began in April 2022, with 158 dyads enrolled as of May 2022. Dissemination of the main study findings is anticipated in 2025.

CONCLUSIONS

MSuubi will assess the effects of a combined intervention (family-based economic empowerment, financial literacy education, and school-based HIV stigma) on HIV stigma among adolescents living with HIV in Uganda. The results will expand our understanding of effective intervention strategies for reducing stigma among HIV-infected and noninfected populations in Uganda and improving HIV treatment outcomes among adolescents living with HIV in sub-Saharan Africa.

Perceived Barriers to HIV Care and Viral Suppression Comparing Newly Diagnosed Women Living with HIV in Rural Uganda with and without a History of Intimate Partner Violence

Intimate partner violence (IPV) is associated with poor HIV care linkage and retention, medication adherence, and viral suppression. However, limited knowledge exists regarding potential mechanisms linking IPV to these outcomes. We aimed to (a) identify the top barriers to accessing HIV care experienced by women living with HIV (WLHIV) who report a history of IPV and have suppressed viral load (VL) versus unsuppressed VL and (b) understand how these barriers influence VL, comparing WLHIV with a history of IPV to WLHIV without a history of IPV. Study data come from newly diagnosed WLHIV in rural Uganda participating in the standard-of-care control arm of a randomized trial (n = 152). Descriptive results ranking mean scores from highest to lowest showed that, among women with a history of IPV, irrespective of viral suppression status, paying for transportation to come to clinic, having to wait at the clinic for long periods of time, and finding a clinic within reasonable travel distance were the top three barriers to accessing HIV care. WLHIV with a history of IPV were significantly more likely to have unsuppressed VL versus suppressed VL if they reported higher levels of difficulty finding a clinic within reasonable travel distance (RRR = 1.7, 95% CI [1.1-2.7]), getting permission to take time off from work (RRR = 1.5, 95% CI [1.0-2.9]), and finding time to come to the clinic for an appointment (RRR = 1.6, 95% CI [1.0-2.6]). The same relationships were not present among WLHIV without a history of IPV, suggesting these barriers and their effect on VL may be uniquely related to IPV. Interventions should address IPV and HIV care continuum outcomes in tandem, targeting barriers to accessing HIV care likely associated with IPV. Additional research is necessary to better understand how IPV relates to HIV care barriers and VL.

Pediatric, adolescent, and young adult cancer in an HIV-infected rural sub-Saharan African population

Youth living with HIV (YLWHIV) have an increased cancer risk. Our objective is to describe the prevalence of medical record (MR) reported suspected cancers in a contemporary cohort of YLWHIV in Uganda that was assembled through MR reviews of patients 10 to 24 years old across 35 Ugandan HIV care health facilities. Clinical data were abstracted to identify suspected cancer cases and information about HIV care. Among 3728 YLWHIV, we identified eight suspected cancer cases. The most common suspected types were Kaposi sarcoma (n=4) followed by lymphoma (n=3). Challenges encountered in data abstraction were missing data for several variables and confirmatory cancer diagnostic information. In follow-up of suspected cases referred for diagnosis at the Uganda Cancer Institute (UCI), none had diagnosis records in UCI files. In addition, ∼18% of patients (n=686) were lost-to-follow-up (LTF) defined as not having returned to the clinic in ≥183 days and three patients died from presumed Kaposi sarcoma. Although our results suggest that cancer is rare in YLWHIV, the possibility that the cancer burden is higher cannot be excluded due to incomplete information in MRs and high LTF rates. Further, our study raises concern that patients referred for diagnosis are not accessing potential life-saving care.

How Do Psychosocial Interventions for Adolescents and Young People Living With HIV Improve Adherence and Viral Load? A Realist Review

PURPOSE

Psychosocial interventions have the potential to support adolescents and young people living with HIV (AYPLHIV) to achieve better HIV outcomes. However, more evidence is needed to understand which interventions are most effective, and the mechanisms driving how they work in practice.

METHODS

We used realist methodologies to generate statements based on evidence from intervention studies and linked evidence included in a systematic review of psychosocial interventions for AYPLHIV. Key data were extracted from available sources to generate cases, including context-mechanism-outcome pathways. Higher level themes were refined iteratively to create a mid-range theory of how these interventions may work.

RESULTS

From 26 resulting cases, 8 statements were crafted, grouped into 3 overarching categories, to describe how these interventions worked. Interventions were overall found to set off mechanisms to improve adherence when (1) responding to individual-level factors to support AYPLHIV (via incorporating agency and empowerment, personalized and/or contextualized approaches, and self-care skills); (2) tailoring delivery strategies to address specific needs (via diverse strategies, longer duration, and digital delivery); and (3) providing supportive resources (via peer and broader support, and structural support and integration into existing services).

DISCUSSION

A collection of diverse mechanisms may individually or collectively drive improved outcomes for AYPLHIV engaged in psychosocial interventions. Recommendations for integrating our findings into practice are discussed.

Health-related needs reported by adolescents living with HIV and receiving antiretroviral therapy in sub-Saharan Africa: a systematic literature review

Introduction

Adolescents living with HIV (ALHIV) on antiretroviral therapy (ART) have specific health needs that can be challenging to deliver. Sub‐Saharan Africa (SSA) is home to 84% of the global population of ALHIV, of whom about 59% receive ART. Several studies in SSA have demonstrated health service gaps due to lack of synchronized healthcare for ALHIV receiving ART. We conducted a systematic review of health‐related needs among ALHIV on ART in SSA to inform decisions and policies on care.

Methods

We searched MEDLINE, Web of Science, EMBASE, PsycINFO, Cochrane library and grey literature for studies reporting health‐related needs among ALHIV receiving ART in SSA, between January 2003 and May 2020.

Results and discussion

Of the 2333 potentially eligible articles identified, 32 were eligible. Eligible studies were published between 2008 and 2019, in 11 countries: Zambia (7), Uganda (6), Tanzania (4), South Africa (4), Kenya (3), Ghana (2), Zimbabwe (2), Rwanda (1), Malawi (1), Botswana (1) and Democratic Republic of Congo (1). Seven categories of health needs among ALHIV were identified. In descending order of occurrence, these were: psychosocial needs (stigma reduction, disclosure and privacy support, and difficulty accepting diagnosis); dependency of care (need for family and provider support, and desire for autonomy); self‐management needs (desire for better coping strategies, medication adherence support and reduced ART side effects); non‐responsive health services (non‐adolescent friendly facility services and non‐compatible school system); need for food, financial and material support; inadequate information about HIV (desire for more knowledge to fight misinformation and misconception); and developmental and growth needs (desire to experience sex, parenthood and love). Ecological analysis identified different priority needs between ALHIV, their caregivers and healthcare providers, including psychosocial needs, financial challenges and non‐responsive health services, respectively.

Conclusions

To respond effectively to the health needs of ALHIV and improve ART adherence, interventions should focus on stigma reduction, disclosure challenges and innovative coping mechanisms for ART. Interventions that address the health needs of ALHIV from the perspective of carers and providers, such as financial support schemes and adolescent‐friendly healthcare strategies, should supplement efforts to improve adolescent ART adherence outcomes.

Factors associated with HIV viral suppression among children and adults receiving antiretroviral therapy in Malawi in 2021: Evidence from the Laboratory Management Information System

OBJECTIVE

To describe the prevalence of HIV viral suppression and assess the factors associated with HIV viral suppression among persons receiving antiretroviral therapy (ART) in Malawi in 2021.

METHODS

Implementation study using routinely collected patient-level HIV RNA-PCR test result data extracted from the national Laboratory Management Information System (LIMS) database managed by the Department of HIV/AIDS in 2021. We calculated frequencies, proportions and odds ratios (OR) of HIV viral suppression with their associated 95% confidence intervals (95%CIs). We performed a random-effects logistic regression to determine the risk factors associated with HIV viral suppression among ART patients, controlling for the spatial autocorrelation between districts and adjusting for other variables.

RESULTS

We evaluated 515,797 adults and children receiving ART and having a viral load test in 2021. Of these, 92.8% had HIV viral suppression. ART patients living in urban areas had lower likelihood of HIV viral suppression than those living in rural areas (adjusted OR [aOR] = 0.95, 95%CI: 0.92-0.99, p = 0.01). There was an increasing trend in HIV viral suppression with increasing ART duration. Routine VL monitoring samples were 39% more likely to have suppressed VL values than confirmatory HIV VL monitoring samples (aOR = 1.39; 95%CI: 1.34-1.43, p < 0.001).

CONCLUSION

This is the first national analysis of Malawi HIV VL data from LIMS. Our findings show the need to particularly consider the urban residents, those below 20 years, males, those on ART for less than a year as well as those on specific ARV regimens in order to persistently suppress HIV VL and consequently achieve the goal of achieving HIV VL suppression by 2030.

Evaluating the impact of social determinants, conditional cash transfers and primary health care on HIV/AIDS: Study protocol of a retrospective and forecasting approach based on the data integration with a cohort of 100 million Brazilians

BACKGROUND

Despite the great progress made over the last decades, stronger structural interventions are needed to end the HIV/AIDS pandemic in Low and Middle-Income Countries (LMIC). Brazil is one of the largest and data-richest LMIC, with rapidly changing socioeconomic characteristics and an important HIV/AIDS burden. Over the last two decades Brazil has also implemented the world's largest Conditional Cash Transfer programs, the Bolsa Familia Program (BFP), and one of the most consolidated Primary Health Care (PHC) interventions, the Family Health Strategy (FHS).

OBJECTIVE

We will evaluate the effects of socioeconomic determinants, BFP exposure and FHS coverage on HIV/AIDS incidence, treatment adherence, hospitalizations, case fatality, and mortality using unprecedently large aggregate and individual-level longitudinal data. Moreover, we will integrate the retrospective datasets and estimated parameters with comprehensive forecasting models to project HIV/AIDS incidence, prevalence and mortality scenarios up to 2030 according to future socioeconomic conditions and alternative policy implementations.

METHODS AND ANALYSIS

We will combine individual-level data from all national HIV/AIDS registries with large-scale databases, including the "100 Million Brazilian Cohort", over a 19-year period (2000-2018). Several approaches will be used for the retrospective quasi-experimental impact evaluations, such as Regression Discontinuity Design (RDD), Random Administrative Delays (RAD) and Propensity Score Matching (PSM), combined with multivariable Poisson regressions for cohort analyses. Moreover, we will explore in depth lagged and long-term effects of changes in living conditions and in exposures to BFP and FHS. We will also investigate the effects of the interventions in a wide range of subpopulations. Finally, we will integrate such retrospective analyses with microsimulation, compartmental and agent-based models to forecast future HIV/AIDS scenarios.

CONCLUSION

The unprecedented datasets, analyzed through state-of-the-art quasi-experimental methods and innovative mathematical models will provide essential evidences to the understanding and control of HIV/AIDS epidemic in LMICs such as Brazil.

"Who am I going to stay with? Who will accept me?": family-level domains influencing HIV care engagement among disengaged adolescents in Kenya

INTRODUCTION

Adolescents living with HIV (ALHIV, ages 10-19) have developmentally specific needs in care, and have lower retention compared to other age groups. Family-level contexts may be critical to adolescent HIV outcomes, but have often been overlooked. We investigated family-level factors underlying disengagement and supporting re-engagement among adolescents disengaged from HIV care.

METHODS

Semi-structured interviews were performed with 42 disengaged ALHIV, 32 of their caregivers and 28 healthcare workers (HCW) in the Academic Model Providing Access to Healthcare (AMPATH) program in western Kenya, from 2018 to 2020. Disengaged ALHIV had ≥1 visit within the 18 months prior to data collection at one of two sites and nonattendance ≥60 days following their last scheduled appointment. HCW were recruited from 10 clinics. Transcripts were analysed through thematic analysis. A conceptual model for family-level domains influencing adolescent HIV care engagement was developed from these themes.

RESULTS

Family-level factors emerged as central to disengagement. ALHIV-particularly those orphaned by the loss of one or both parents-experienced challenges when new caregivers or unstable living situations limited support for HIV care. These challenges were compounded by anticipated stigma; resultant non-disclosure of HIV status to household members; enacted stigma in the household, with overwhelming effects on adolescents; or experiences of multiple forms of trauma, which undermined HIV care engagement. Some caregivers lacked finances or social support to facilitate care. Others did not feel equipped to support adolescent engagement or adherence. Regarding facilitators to re-engagement, participants described roles for household disclosure; and solidarity from caregivers, especially those also living with HIV. Family-level domains influencing HIV care engagement were conceptualized as follows: (1) adolescent living situation and contexts; (2) household material resources or poverty; (3) caregiver capacities and skills to support adolescent HIV care; and (4) HIV stigma or solidarity at the household level.

CONCLUSIONS

Family-level factors are integral to retention in care for ALHIV. The conceptual model developed in this study for family-level influences on care engagement may inform holistic approaches to promote healthy outcomes for ALHIV. Developmentally appropriate interventions targeting household relationships, disclosure, HIV stigma reduction, HIV care skills and resources, and economic empowerment may promote adolescent engagement in HIV care.

Implementation and Adaptation of a Combined Economic Empowerment and Peer Support Program Among Youth Living With HIV in Rural Rwanda

Background: Youth living with HIV in rural Rwanda experience poor clinical outcomes. In 2017, we implemented Adolescent Support Groups (ASGs), which provided economic incentives and peer support to youth aged 15-25. Methods: We assessed the ASG program using programmatic and electronic medical records. We described group composition and achievement on three indicators used to determine economic incentive levels: (1) quarterly pharmacy visit attendance, (2) biannual savings target achievement, and (3) annual viral suppression. Results: In total, 324 members enrolled in 34 ASGs. Group size and member ages varied more than anticipated. Groups performed well on pharmacy visit attendance (median quarterly group attendance range 91-100%) and on achieving savings targets (median biannual achievement range 80–83%). The viral suppression indicator could not be implemented as planned. Conclusion: To reflect contextual realities, adaptations in enrollment, indicator evaluation, and awarding of incentives occurred during implementation. Future research should assess whether these adaptations affected results.

Receipt of a combined economic and peer support intervention and clinical outcomes among HIV-positive youth in rural Rwanda: A retrospective cohort

INTRODUCTION

To combat poor clinical outcomes among HIV-positive youth, Partners In Health/Inshuti Mu Buzima (PIH/IMB) implemented Adolescent Support Groups (ASGs), which combined peer support and group-based economic incentives to promote treatment adherence, economic empowerment, and viral suppression. This study assesses the association between ASG membership and clinical outcomes among HIV-positive youth living in rural Rwanda.

METHODS

We constructed a retrospective cohort using PIH/IMB's electronic medical record (EMR) system. ASG members were matched to control youth within strata defined by health facility, year of birth, and whether the patient had enrolled in HIV services as a pediatric patient, as a PMTCT mother, or through another route. Our 12-month outcomes of interest were a) death-free retention in care, b) death-free retention with active follow-up, c) ≥80% adherence to appointment keeping, and d) viral load suppression (<20 copies/ml). We used generalized linear mixed models to estimate odds ratios for the association between ASG participation and each outcome. To mitigate possible unmeasured confounding, we additionally included participant data from the previous year and conducted a difference-in-difference analysis for each outcome to assess whether ASG members experienced greater changes compared to control youth over a similar period.

RESULTS

Two-hundred sixty ASG members were identified in the EMR and matched to 209 control youth for analysis. After 12 months of follow-up, ASG members had similar outcomes to the control youth in terms of death-free retention (93% vs. 94%), death-free retention with active follow-up (79% vs. 78%), ≥80% adherence to appointment keeping (42% vs. 43%), and viral suppression (48% vs. 51%). We did not observe any significant associations between ASG participation and clinical outcomes in crude or adjusted models, nor did ASG members experience greater improvements than control youth in our difference-in-difference analysis.

CONCLUSIONS

The ASG program did not improve retention, appointment adherence, or viral suppression among HIV positive youth in rural Rwanda. Challenges implementing the intervention as designed underscore the importance of incorporating implementation strategies and youth perspectives in program design. This population remains vulnerable to poor clinical outcomes, and additional research is needed to better serve youth living with HIV.

Kenyan HIV Clinics With Youth-Friendly Services and Trained Providers Have a Higher Prevalence of Viral Suppression Among Adolescents and Young Adults: Results From an Observational Study

ABSTRACT

Sustained viral suppression in adolescents and young adults living with HIV (AYALWH) is necessary for epidemic control. We evaluated facility and individual correlates of viral suppression using programmatic data from AYALWH between ages 10 and 24 years at 24 HIV clinics in Kenya. Binomial regression was used to evaluate correlates of viral load (VL) suppression (<1,000 copies/ml). Of 5,316 AYALWH on antiretroviral therapy ≥6 months, 2,081 (39%) had VLs available in the medical record, of which 76% were virally suppressed. In multivariable analyses, antiretroviral therapy initiation among AYALWH older than 10 years was associated with higher viral suppression than initiation younger than 10 years (adjusted risk ratio [aRR] 10-14 = 1.03, 95% confidence interval [CI] 0.97-1.10; aRR 15-19 = 1.30, 95% CI 1.19-1.41; aRR 20-24 = 1.43, 95% CI 1.24-1.63). Facilities with both youth-friendly services (YFS) and trained providers had significantly higher VL suppression compared with facilities without YFS or trained providers (adjusted odds ratio: 2.07, 95% CI: 1.71-2.52). Viral suppression remains suboptimal among AYALWH. YFS and trained providers plus greater use of VL data may help increase viral suppression among AYALWH.

Understanding patterns of family support and its role on viral load suppression among youth living with HIV aged 15 to 24 years in southwestern Uganda

BACKGROUND

Active family support helps as a buffer against adverse life events associated with antiretroviral therapy (ART) uptake and adherence. There is limited data available to explain how family support shapes and affects individual healthcare choices, decisions, experiences, and health outcomes among youth living with HIV (YLWH). We aimed to describe family support patterns and its role in viral load suppression among YLWH at a rural hospital in southwestern Uganda.

METHODS

We performed a mixed-method cross-sectional study between March and September 2020, enrolling 88 eligible YLWH that received ART for at least 6 months. Our primary outcome of interest was viral load suppression, defined as a viral load detected of ≤500 copies/mL. Data analysis was performed using Statistical Package for Social Sciences version 20. Fifteen individuals were also purposively selected from the original sample and participated in an in-depth interview that was digitally recorded. Generated transcripts were coded and categories generated manually using the inductive content analytic approach. All participants provided written consent or guardian/parent assent (those <18 years) to participate in the study.

RESULTS

Forty-nine percent of YLWH were females, the median age was 21 (IQR: 16-22) years. About half of the participants (53%) stayed with a family member. A third (34%) of participants had not disclosed their status to any person they stayed with at home. Only 23% reported getting moderate to high family social support (Median score 2.3; IQR: 1.6-3.2). Seventy-eight percent of YLWH recorded viral load suppression. Viral load suppression was associated with one living with a parent, sibling, or spouse (AOR: 6.45; 95% CI: 1.16-16.13; P = .033), having a primary caretaker with a regular income (AOR: 1.57; 95% CI: 1.09-4.17; P = .014), and living or communicating with family at least twice a week (AOR: 4.2; 95% CI: 1.65-7.14; P = .003). Other significant factors included youth receiving moderate to high family support (AOR: 12.11; 95% CI: 2.06-17.09; P = .006) and those that perceived family support in the last 2 years as helpful (AOR: 1.98; 95% CI: 1.34-3.44; P = .001). HIV stigma (AOR: 0.10; 95% CI: 0.02-0.23; P = .007) and depression (AOR: 0.31; 95% CI: 0.06-0.52; P = .041) decreased viral load suppression. Qualitative data showed that dysfunctional family relationships, economic insecurity, physical separation, HIV- and disclosure-related stigma, past and ongoing family experiences with HIV/ART affected active family support. These factors fueled feelings of abandonment, helplessness, discrimination, and economic or emotional strife among YLWH.

CONCLUSION

Our data showed that living with a family member, having a primary caretaker with a regular income, living or communicating with family members regularly, and reporting good family support were associated with viral load suppression among YLWH in rural southwestern Uganda. Experiencing depression due to HIV and or disclosure-related stigma was associated with increased viral load. All YLWH desire ongoing emotional, physical, and financial support from immediate family to thrive and take medications daily and timely. Future interventions should explore contextual community approaches that encourage acceptance, disclosure, and resource mobilization for YLWH who rely on family support to use ART appropriately.

Preliminary Effectiveness of Group Interpersonal Psychotherapy for Young Kenyan Mothers With HIV and Depression: A Pilot Trial

OBJECTIVE

The authors adopted a task-sharing strategy in which lay health workers delivered group interpersonal psychotherapy (IPT-G) in primary care clinics in Nairobi, Kenya, to young mothers with HIV and depression. The study examined the acceptability, feasibility, and effectiveness of IPT-G in improving depression and antiretroviral therapy adherence.

METHODS

Twenty-four mothers (ages 18-24 years and 6-12 weeks postpartum) participated. The women were randomly assigned to IPT-G or to a waitlist. Eight lay providers administered the IPT-G sessions across 8 weeks. The primary outcome was pre- to postintervention change in depression scores as measured on the Edinburgh Postnatal Depression Scale. The secondary outcome was antiretroviral therapy adherence. All waitlist participants subsequently received the intervention, and a secondary outcome, within-group analysis, was conducted and included those participants.

RESULTS

Participants' median age was 23.0 years, 17 (71%) lived with a partner, and 19 (79%) had fewer than two children. The intervention group had a mean±SD depression score of 15.9±4.3 at baseline and 6.8±7.0 postintervention. For the waitlist control group, the mean score was 17.3±5.9 at baseline and 13.2±6.6 at the first follow-up. Waitlist participants had significantly greater mean depression scores than did intervention group participants at the first follow-up (after the intervention group's 8-week IPT-G) (β=6.42, 95% confidence interval=1.17 to 11.66, p=0.017). No difference was observed between groups in antiretroviral therapy adherence.

CONCLUSIONS

This study provides preliminary evidence that IPT-G led by community health workers may have benefits for postpartum depression among young mothers with HIV.

Group counselling for adherence support among young people failing first-line antiretroviral therapy in Zimbabwe

Background

Sub-optimal adherence to antiretroviral therapy (ART) is reportedly worse amongst young people living with HIV (YPLHIV). Group adherence counselling can be useful to improve adherence.

Objectives

We evaluated an enhanced adherence counselling group intervention (EACGI) amongst YPLHIV failing a non-nucleoside reverse transcriptase (NNRTI)-based first-line ART regimen.

Method

This was a retrospective cohort study using routinely collected data of YPLHIV failing NNRTI-based first-line ART. Patients with confirmed virological failure were referred for EACGI, a 12-week curriculum of weekly, 1.5-h sessions accommodating 8–15 people per group. It aimed to facilitate readiness to switch to second-line ART and improve adherence through a mental health intervention. Viral loads of HIV were measured pre-EACGI; at baseline; 3, 6 and 12 months post switch.

Results

Fifty-seven patients aged 13–25 years were invited to EACGI and followed for up to 48 weeks. Thirty-three (58%) patients attended at least four sessions, whilst 24 (42%) attended none. Amongst those who attended none, two (8%) were transferred out, three (13%) were lost to follow-up and two (8%) had died by week 48 of follow-up, whilst all who attended were still in care. By week 48, amongst patients still in care, 29%, 44% and 67% of those who attended no sessions, 4–9 and 10–12 sessions, respectively, had viral loads of < 50 copies/mL.

Conclusion

An EACGI is a promising intervention for YPLHIV failing ART prior to treatment switch, leading to improved adherence. This study’s findings support the need for further enquiry into rigorous, evidence-based multilevel adherence interventions that are acceptable and effective for YPLHIV.

Psychosocial interventions for improving engagement in care and health and behavioural outcomes for adolescents and young people living with HIV: a systematic review and meta-analysis

INTRODUCTION

Adolescents and young people comprise a growing proportion of new HIV infections globally, yet current approaches do not effectively engage this group, and adolescent HIV-related outcomes are the poorest among all age groups. Providing psychosocial interventions incorporating psychological, social, and/or behavioural approaches offer a potential pathway to improve engagement in care and health and behavioural outcomes among adolescents and young people living with HIV (AYPLHIV).

METHODS

A systematic search of all peer-reviewed papers published between January 2000 and July 2020 was conducted through four electronic databases (Cochrane Library, PsycINFO, PubMed and Scopus). We included randomized controlled trials evaluating psychosocial interventions aimed at improving engagement in care and health and behavioural outcomes of AYPLHIV aged 10 to 24 years.

RESULTS AND DISCUSSION

Thirty relevant studies were identified. Studies took place in the United States (n = 18, 60%), sub-Saharan Africa (Nigeria, South Africa, Uganda, Zambia, Zimbabwe) and Southeast Asia (Thailand). Outcomes of interest included adherence to antiretroviral therapy (ART), ART knowledge, viral load data, sexual risk behaviours, sexual risk knowledge, retention in care and linkage to care. Overall, psychosocial interventions for AYPLHIV showed important, small-to-moderate effects on adherence to ART (SMD = 0.3907, 95% CI: 0.1059 to 0.6754, 21 studies, n = 2647) and viral load (SMD = -0.2607, 95% CI -04518 to -0.0696, 12 studies, n = 1566). The psychosocial interventions reviewed did not demonstrate significant impacts on retention in care (n = 8), sexual risk behaviours and knowledge (n = 13), viral suppression (n = 4), undetectable viral load (n = 5) or linkage to care (n = 1) among AYPLHIV. No studies measured transition to adult services. Effective interventions employed various approaches, including digital and lay health worker delivery, which hold promise for scaling interventions in the context of COVID-19.

CONCLUSIONS

This review highlights the potential of psychosocial interventions in improving health outcomes in AYPLHIV. However, more research needs to be conducted on interventions that can effectively reduce sexual risk behaviours of AYPLHIV, as well as those that can strengthen engagement in care. Further investment is needed to ensure that these interventions are cost-effective, sustainable and resilient in the face of resource constraints and global challenges such as the COVID-19 pandemic.

Predicting the individualized risk of poor adherence to ART medication among adolescents living with HIV in Uganda: the Suubi+Adherence study

INTRODUCTION

Achieving optimal adherence to antiretroviral therapy (ART) among adolescents living with HIV (ALWHIV) is challenging, especially in low-resource settings. To help accurately determine who is at risk of poor adherence, we developed and internally validated models comprising multi-level factors that can help to predict the individualized risk of poor adherence among ALWHIV in a resource-limited setting such as Uganda.

METHODS

We used data from a sample of 637 ALWHIV in Uganda who participated in a longitudinal study, "Suubi+Adherence" (2012 to 2018). The model was developed using the Least Absolute Shrinkage and Selection Operator (LASSO) penalized regression to select the best subset of multi-level predictors (individual, household, community or economic-related factors) of poor adherence in one year's time using 10-fold cross-validation. Seventeen potential predictors included in the model were assessed at 36 months of follow-up, whereas adherence was assessed at 48 months of follow-up. Model performance was evaluated using discrimination and calibration measures.

RESULTS

For the model predicting poor adherence, five of the 17 predictors (adherence history, adherence self-efficacy, family cohesion, child poverty and group assignment) were retained. Its ability to discriminate between individuals with and without poor adherence was acceptable; area under the curve (AUC) = 69.9; 95% CI: 62.7, 72.8. There was no evidence of possible areas of miscalibration (test statistic = 1.20; p = 0.273). The overall performance of the model was good.

CONCLUSIONS

Our findings support prediction modelling as a useful tool that can be leveraged to improve outcomes across the HIV care continuum. Utilizing information from multiple sources, the risk prediction score tool applied here can be refined further with the ultimate goal of being used in a screening tool by practitioners working with ALWHIV. Specifically, the tool could help identify and provide early interventions to adolescents at the highest risk of poor adherence and/or viral non-suppression. However, further fine-tuning and external validation may be required before wide-scale implementation.

The efficacy and cost-effectiveness of a family-based economic empowerment intervention (Suubi + Adherence) on suppression of HIV viral loads among adolescents living with HIV: results from a Cluster Randomized Controlled Trial in southern Uganda

INTRODUCTION

Evidence from low-resource settings indicates that economic insecurity is a major barrier to HIV treatment adherence. Economic empowerment (EE) interventions have the potential to improve adherence outcomes among adolescents living with HIV (ALWHIV) by mitigating the effects of poverty. This study aims to assess the efficacy and cost-effectiveness of a savings-led family-based EE intervention, Suubi + Adherence, aimed at improving antiretroviral therapy (ART) adherence outcomes ALWHIV in Uganda.

METHODS

Adolescents (mean age 12 years at enrolment; 56% female) receiving ART for HIV at 39 health centres were randomized to Suubi + Adherence intervention (n = 358) or bolstered standard of care (BSOC; n = 344). A difference-in-differences analysis was employed to assess the change in the proportion of virally suppressed adolescents (HIV RNA viral load <40 copies/mL) over 24 months. The cost-effectiveness analysis examined how much the intervention cost to virally suppress one additional adolescent relative to BSOC from the healthcare provider perspective.

RESULTS

At 24 months, the intervention was associated with an 8.85-percentage point [95% confidence interval (CI) 0.80 to 16.90 percentage points] increase in the proportion of virally suppressed adolescents between the study arms (p = 0.032). Per-participant costs were US$177 and US$263 for the BSOC and intervention groups respectively. The incremental cost of virally suppressing one additional adolescent was estimated at US$970 [95% CI, US$508 to 10,725] over two years.

CONCLUSIONS

Our results support the integration of family-based EE interventions into adherence-support strategies as part of routine HIV care in low-resource settings to address the underlying economic drivers of poor ART adherence among ALWHIV. Moreover, per-participant costs to achieve viral suppression do not seem prohibitive compared to other community-based adherence interventions targeted at ALWHIV in low-resource settings. Further research on combination interventions at the nexus of economic security and HIV treatment and care is needed to inform the development of feasible and scalable HIV policies and programmes.

Evaluating potential mediators for the impact of a family-based economic intervention (Suubi+Adherence) on the mental health of adolescents living with HIV in Uganda

INTRODUCTION

Many adolescents living with HIV in sub-Saharan Africa (SSA) experience poverty and have access to limited resources, which can impact HIV and mental health outcomes. Few studies have analyzed the impact of economic empowerment interventions on the psychosocial wellbeing of adolescents living with HIV in low resource communities, and this study aims to examine the mediating mechanism(s) that may explain the relationship between a family economic empowerment intervention (Suubi + Adherence) and mental health outcomes for adolescents (ages 10-16 at enrollment) living with HIV in Uganda.

METHOD

We utilized data from Suubi + Adherence, a large-scale six-year (2012-2018) longitudinal randomized controlled trial (N = 702). Generalized structural equation models (GSEMs) were conducted to examine 6 potential mediators (HIV viral suppression, food security, family assets, and employment, HIV stigma, HIV status disclosure comfort level, and family cohesion) to determine those that may have driven the effects of the Suubi + Adherence intervention on adolescents' mental health.

RESULTS

Family assets and employment were the only statistically significant mediators during follow-up (β from -0.03 to -0.06), indicating that the intervention improved family assets and employment which, in turn, was associated with improved mental health. The proportion of the total effect mediated by family assets and employment was from 42.26% to 71.94%.

CONCLUSIONS

Given that mental health services provision is inadequate in SSA, effective interventions incorporating components related to family assets, employment, and financial stability are crucial to supporting the mental health needs of adolescents living with HIV in under-resourced countries like Uganda. Future research should work to develop the sustainability of such interventions to improve long-term mental health outcomes among this at-risk group.

Characteristics of adolescents aged 15-19 years living with vertically and horizontally acquired HIV in Nampula, Mozambique

BACKGROUND

Adolescents living with HIV (ALHIV) 15-19 years of age are a growing proportion of all people living with HIV globally and the population includes adolescents with vertically acquired HIV (AVH) and behaviorally acquired HIV (ABH).

METHODS

We conducted a survey to measure sociodemographic characteristics, educational status, health history, and antiretroviral therapy (ART) adherence among a convenience sample of ALHIV at three government health facilities in 2019 in Nampula, Mozambique. ALHIV 15-19 years on ART, including females attending antenatal care, were eligible. Routine HIV care data were extracted from medical charts. Classification of ALHIV by mode of transmission was based on medical charts and survey data. ALHIV who initiated ART <15 years or reported no sex were considered AVH; all others ABH. Frequencies were compared by sex, and within sex, by mode of transmission (AVH vs. ABH) using Chi-square, Fishers exact tests and Wilcoxon rank-sum tests.

RESULTS

Among 208 ALHIV, 143 (69%) were female and median age was 18 years [interquartile range (IQR) 16-19]. Just over half of ALHIV (53%) were in or had completed secondary or higher levels of education; the most common reason for not being in school reported by 36% of females was pregnancy or having a child. Of all ALHIV, 122 (59%) had VL data, 62% of whom were <1000 copies/mL. Almost half (46%) of ALHIV reported missing ARVs ≥ 1 day in the past month (62% of males vs. 39% of females; p = 0.003). Just over half (58%) of ALHIV in relationships had disclosed their HIV status: 13% of males vs. 69% of females (p<0.001). Among sexually active males, 61% reported using a condom at last sex compared to 26% of females (p<0.001). Among female ALHIV, 50 (35%) were AVH and 93 (65%) were ABH, 67% of whom were not in school compared to 16% of ABH, (p<0.001).

DISCUSSION

Data from our study underscore the high level of deprivation among ALHIV enrolled in HIV care in Mozambique, as well as important disparities by sex and mode of transmission. These data can inform the development of effective interventions for this complex and important population.

Engaging community and governmental partners in improving health and mental health outcomes for children and adolescents impacted by HIV/AIDS in Uganda

The African region remains the world’s most affected region in the HIV epidemic. A related consequence of HIV/AIDS in sub-Saharan Africa (SSA), including in Uganda, is the high prevalence of children and adolescents who have lost one or both parents to this virus or who have been perinatally infected. Guided by the Practical, Robust Implementation and Sustainability (PRISM) framework, this paper describes the strategies by which we have engaged community and government partners in research using three NIH-funded randomized clinical trials testing an evidence-based combination intervention aimed at improving health and mental health outcomes among children and adolescents impacted by HIV/AIDS in Uganda. We specifically lay out four strategies that have been used to facilitate stakeholder engagement, namely consultative meetings, stakeholder accountability meetings, training of key players (task-shifting), and policymaker engagement. We emphasize that community collaborations and partnerships are especially critical when implementing combination interventions that require a high level of communication and coordination among multiple implementation partners. We underline that building and sustaining long-term relationships and communication with the stakeholders can allow the researchers to successfully design rigorous studies that are responsive to local needs and can make a difference especially in low-resource settings. Finally, we highlight that the process of engagement and collaboration can be guided by conceptual frameworks.

Integrated psychosocial, economic strengthening, and clinical service-delivery to improve health and resilience of adolescents living with HIV and their caregivers: Findings from a prospective cohort study in Zambia

BACKGROUND

Children and youth are profoundly impacted groups in Zambia's HIV epidemic. To evaluate delivery of integrated psychosocial, economic strengthening, and clinical services to HIV-affected households through the Zambia Family (ZAMFAM) Project, a prospective cohort study compared socio-economic, psychosocial, and health outcomes among ZAMFAM beneficiaries to non-beneficiaries.

METHODS

In July-October 2017, 544 adolescents living with HIV (ALHIV) aged 5-17 years and their adult caregivers were recruited from Central (ZAMFAM implementation sites) and Eastern (non-intervention sites) Provinces. Structured interviews at baseline and one-year follow-up assessed household characteristics, socio-economic wellbeing, and health service utilization. Poisson regression with generalized estimating equations measured one-year changes in key health and socio-economic indicators, comparing ZAMFAM beneficiaries to non-beneficiaries.

RESULTS

Overall, 494 households completed two rounds of assessment (retention rate: 91%) Among ALHIV, improvements in current antiretroviral therapy use over time (Adjusted Prevalence Rate Ratio [aPRR] = 1.06, 95% Confidence Interval [95% CI]: 1.01-1.11) and reductions in non-household labor (aPRR = 0.44, 95% CI: 0.20-0.99) were significantly larger among ZAMFAM beneficiaries than non-beneficiaries. For caregivers, receiving ZAMFAM services was associated with significant reductions in HIV-related stigma (aPRR = 0.49, 95% CI: 0.28-0.88) and perceived negative community attitudes towards HIV (aPRR = 0.77, 95% CI: 0.62-0.96). Improvements in caregiver capacity to pay for unexpected (aPRR = 1.54, 95% CI: 1.17-2.04) and food-related expenses (aPRR = 1.48, 95% CI: 1.16-1.90), as well as shared decision-making authority in household spending (aPRR = 1.41, 95% CI: 1.04-1.93) and self-reported good or very good health status (aPRR = 1.46, 95% CI: 1.14-1.87), were also significantly larger among ZAMFAM beneficiaries.

CONCLUSIONS

Significant improvements in caregivers' financial capacity were observed among households receiving ZAMFAM services, with few changes in health or wellbeing among ALHIV. Integrated service-delivery approaches like ZAMFAM may yield observable socio-economic improvements in the short-term. Strengthening community-based delivery of psychosocial and health support to ALHIV is encouraged.

Suubi+Adherence-Round 2: A study protocol to examine the longitudinal HIV treatment adherence among youth living with HIV transitioning into young adulthood in Southern Uganda

BACKGROUND

Youth living with HIV (YLHIV) in Sub-Saharan African (SSA) are less likely to adhere to antiretroviral therapy (ART) and other health-related regimens. As a consequence, YLHIV are not only at risk for health problems and mental health comorbidities, but are also at risk for cognitive deficits, including in areas of memory and executive functioning. The Suubi+Adherence study followed 702 adolescents (10-16 years of age) receiving bolstered standard of care and a family economic empowerment intervention comprising an incentivized youth financial savings account (YSA) augmented with financial literacy training (FLT) and peer mentorship. The study findings pointed to superior short-term viral suppression and positive adolescent health and mental health functioning among participants receiving the intervention. The original group of adolescents who received Suubi+Adherence are now transitioning into young adulthood. This paper presents a protocol for the follow-up phase titled Suubi+Adherence Round 2.

METHODS

The original cohort in Suubi+Adherence will be tracked for an additional five years (2020-2025). Specifically, the long term follow-up will allow to: 1) ascertain the extent to which the short term outcomes identified in the first 6 years of the intervention are maintained as the same group transitions through young adulthood; and 2) address new scientific questions regarding ART adherence; HIV care engagement; protective health behaviors; and the potential of FEE to mitigate the development of HIV-associated neurocognitive disorders in YLHIV. Additionally, the team examines the potential mechanisms through which the observed long-term outcomes happen. Moreover, the Suubi+Adherence-Round 2 adds a qualitative component and extends the cost effectiveness component.

DISCUSSION

Guided by asset and human development theories, Suubi+Adherence-R2 will build on the recently concluded Suubi+Adherence study to conduct one of the largest and longest running studies of YLHIV in SSA as they transition into young adulthood. The study will address new scientific questions regarding long-term ART adherence, HIV care engagement, protective health behaviors, and the potential of FEE to mitigate the development of HIV-associated neurocognitive disorders in YLHIV. The findings may inform efforts to improve HIV care among Uganda's YLHIV, with potential replicability in other low-resource countries.

From "4Rs and 2Ss" to "Amaka Amasanyufu" (Happy Families): Adapting a U.S.-based Evidence-Based Intervention to the Uganda Context

In Uganda, one in five children presents mental health challenges, including disruptive behavior disorders (DBDs). DBDs can persist through adulthood and result in negative outcomes. Effective interventions for DBDs have been developed and tested in high-poverty communities in developed countries. Yet, most African countries, such as Uganda, lack such interventions. This paper describes the adaptation process of an evidence-based intervention of U.S. origin to optimize fit to context with intervention fidelity, as part of a randomized trial conducted with youth that exhibit behavioral challenges and their caregivers in 30 schools in Uganda. The process involved: initial meetings with headteachers and teachers to introduce the study and the main concepts of the intervention; initial manual review focusing on 4Rs and 2Ss content by the Uganda team; engagement of community stakeholders for additional feedback on content and cultural relevance; final revision of the manual; and collection of children's drawings for the illustration of the manual. This paper describes both similarities and differences between the original and adapted intervention content and methods of delivery. The findings also highlight the importance of involving community stakeholders in the adaptation process.

Gender, HIV knowledge and prevention attitudes among adolescents living with HIV participating in an economic empowerment intervention in Uganda

HIV disproportionately affect adolescent girls and young women in sub-Saharan Africa. In Uganda, the HIV prevalence is four times higher in adolescent girls compared to boys. This study examined gender, HIV general and clinical knowledge, and prevention attitudes among adolescents living with HIV in Uganda. Data from a cluster randomized clinical trial were analyzed. A total of 702 adolescents (average age of 12.4) were randomized to either a control arm receiving bolstered standard of care or the treatment arm receiving bolstered standard of care plus a family economic empowerment intervention to support medication adherence. Ordinary Least Squares models that adjust for clustering of adolescents within health clinics were conducted. No gender differences were observed in HIV knowledge and prevention attitudes at baseline. However, at 12-months follow-up, boys were more likely than girls to report correct HIV general knowledge (d = 0.21), clinical knowledge (d = 0.48), and favorable prevention attitudes (d = 0.27). The intervention was not associated with any of the outcomes. Given the high HIV prevalence among adolescents, specifically girls, there is need to develop and/or tailor existing programs and interventions that equip adolescent girls with comprehensive knowledge and prevention attitudes, that are culturally appropriate, to reduce HIV transmission and reinfection within this population.

Interventions to Improve Antiretroviral Therapy Adherence Among Adolescents and Youth in Low- and Middle-Income Countries: A Systematic Review 2015-2019

Adolescents and youth living with HIV have poorer antiretroviral treatment (ART) adherence and viral suppression outcomes than all other age groups. Effective interventions promoting adherence are urgently needed. We reviewed and synthesized recent literature on interventions to improve ART adherence among this vulnerable population. We focus on studies conducted in low- and middle-income countries (LMIC) where the adolescent and youth HIV burden is greatest. Articles published between September 2015 and January 2019 were identified through PubMed. Inclusion criteria were: [1] included participants ages 10-24 years; [2] assessed the efficacy of an intervention to improve ART adherence; [3] reported an ART adherence measurement or viral load; [4] conducted in a LMIC. Articles were reviewed for study population characteristics, intervention type, study design, outcomes measured, and intervention effect. Strength of each study's evidence was evaluated according to an adapted World Health Organization GRADE system. Articles meeting all inclusion criteria except being conducted in an LMIC were reviewed for results and potential transportability to a LMIC setting. Of 108 articles identified, 7 met criteria for inclusion. Three evaluated patient-level interventions and four evaluated health services interventions. Of the patient-level interventions, two were experimental designs and one was a retrospective cohort study. None of these interventions improved ART adherence or viral suppression. Of the four health services interventions, two targeted stable patients and reduced the amount of time spent in the clinic or grouped patients together for bi-monthly meetings, and two targeted patients newly diagnosed with HIV or not yet deemed clinically stable and augmented clinical care with home-based case-management. The two studies targeting stable patients used retrospective cohort designs and found that adolescents and youth were less likely to maintain viral suppression than children or adults. The two studies targeting patients not yet deemed clinically stable included one experimental and one retrospective cohort design and showed improved ART adherence and viral suppression outcomes. ART adherence and viral suppression outcomes remain a major challenge among adolescents and youth. Intensive home-based case management models of care hold promise for improving outcomes in this population and warrant further research.

Cancer in Youth Living With HIV (YLWHIV): A Narrative Review of the Access to Oncological Services Among YLWHIV and the Role of Economic Strengthening in Child Health

Youth Living with HIV/AIDS (YLWHIV) have a higher risk of developing immunodeficiency related illnesses including certain cancers than their general population counterparts of the same age. This narrative review of current available literature describes factors associated with pediatric access to oncological services, and the role economic strengthening could play in improving health outcomes for this vulnerable population. Findings suggest that both HIV-infected and -uninfected children living in low and middle-income countries struggle with access and adherence to cancer treatment and care. Cost of treatment is a major barrier to access and adherence. Asset-building savings programs may increase financial security and subsequently result in better health outcomes although they have not been utilized to improve access to cancer treatment.

Relationship between economic insecurity, inflammation, monocyte activation and intestinal integrity in children living with HIV in Uganda

We aimed to evaluate differences in socio-economic variables in a Ugandan cohort of children with perinatally acquired HIV (PHIVs), HIV exposed uninfected (HEU) and HIV unexposed uninfected (HIV-) children and their associations with markers of inflammation and intestinal integrity. This is a cross-sectional study in 57 PHIV, 59 HEU and 56 HIV - children aged 2-10 years old enrolled in Uganda. Mean age of all participants was 7 years and 55% were girls. Compared to HEU and HIV - children, PHIVs were more likely to have parents that only completed a primary education, live in a household without electricity and live in poverty (p≤0.034). PHIVs living in poverty had higher IL-6 (p=0.006), those with lack of electricity had higher hsCRP, IL6, sTNFRII and d-dimer (p≤0.048) and PHIVs with an unprotected water source had higher IL6 and d-dimer (p≤0.016). After adjusting for demographic and HIV variables, IL-6 and d-dimer remained associated with lack of electricity and having an unprotected water source only in PHIVs (p<0.019). Our findings suggest that addressing economic insecurity may mitigate the persistent low-level inflammation in HIV that lead to many end organ disease. Longitudinal studies are needed to better understand the impact of socioeconomic factors on HIV inflammation and comorbidities.

Antiretroviral adherence for adolescents growing up with HIV: understanding real life, drug delivery and forgiveness

Poorer adherence to medication is normal in adolescence and is one of a range of risk-taking behaviours common during a developmental stage that encompasses enormous cognitive, physical, sexual, social and emotional change. For adolescents living with human immunodeficiency virus (HIV) infection, poor adherence to antiretroviral therapy (ART) confers two significant challenges: poor health, but also the specific additional burden of onward transmission to partners. Late adolescence (15-19 years) is the only age group where HIV-associated mortality is rising, driven by poor adherence to ART and lack of access to second-line therapy, particularly amongst surviving perinatally infected young people. A previous lack of well-powered randomised multimodal behavioural ART adherence interventions specifically targeting adolescents is now being addressed and ongoing studies registered to ClinicalTrials.gov are described in the context of previous data. Accepting that despite enhanced support, some adolescents will continue to struggle with adherence, we must address how best to use existing ART agents to reduce mortality and allow adolescents the time to mature into adult life. Single-tablet regimens with a high genetic barrier to resistance based on integrase inhibitors and boosted protease inhibitors exist, but global access, in resource limited settings of young people living with HIV reside, is limited. Pragmatically, such regimens tolerate the intermittent adherence so characteristic of adolescence, preserving immune function, without the rapid evolution of resistance. The potential role of long-acting injectable ART, specifically cabotegravir and rilpivirine, is discussed and future strategies including ultra-long-acting drug-delivery systems and broadly neutralising monoclonal antibodies explored.
