AIDSImpact special issue: latent class analysis of ART barriers among adolescents and young adults living with HIV in South Africa

This study examined adherence to antiretroviral therapy (ART) among adolescents and young adults living with HIV in South Africa. Using survey data from 857 youth on ART, the study employed latent class analysis to identify subgroups based on self-reported reasons for missed ART doses. Three distinct classes emerged: the largest class (85%) occasionally forgot to take their medication or missed a dose because others were around, the second class (9%) missed doses only due to feeling sick, and the third class (6%) faced multiple barriers such as forgetting, feeling sick, worrying about side effects, or doubting the effectiveness of ART. Youth who reported multiple barriers to adherence had significantly lower adjusted odds (AOR = 0.35, 95% CI = 0.16-0.78) of reporting 90% past month adherence compared to those who occasionally forgot their medication. Additionally, contextual factors such as food security, being treated well at the clinic, and being accompanied to the clinic were associated with higher odds of adherence. The findings highlight the importance of considering co-occurring barriers to adherence and tailoring interventions accordingly. Addressing contextual factors, such as ensuring food security and providing supportive clinic environments, is also crucial for promoting optimal adherence among adolescents and young adults living with HIV.

COVID-19 pandemic stressors, familial discord, and anxiety among adolescents living with HIV in South Africa: pathways to non-adherence

Adolescents living with HIV (ALHIV) have poorer adherence to antiretroviral treatment (ART). This study investigates the interconnectivity of stressors induced by the COVID-19 pandemic, anxiety and family dynamics on adolescents' adherence to ART. A telephone survey was conducted among 196 South African ALHIV previously enrolled in support groups. Generalized structural equations modeling was used to understand how pandemic-related stressors affected ART adherence. Respondents reported experiencing life stressors since the implementation of COVID-19 restrictions, including doing worse at school (32%), loss of household income (44%) and less food available (38%). Forty-two percent reported greater verbal aggression from adults at home and 60% experienced anxiety. The structural equations model demonstrated a direct path from experiencing life stressors to increased verbal aggression from caregivers, which led to anxiety and ultimately, poorer ART adherence. Each stressor experienced increased the odds of experiencing verbal aggression by 51% (OR=1.51, 95%CI=1.14-2.00) which, in turn, increased the odds of having anxiety four-fold (OR=4.1, 95%C =2.16-7.76). Anxiety was associated with a 74% reduction in the odds of being fully ART adherent (OR=0.26, 95%CI=0.08-0.81). COVID-19-induced stressors exacerbated the mental and physical vulnerability of ALHIV. Findings elucidate how both discord at home and anxiety can result in poorer ART adherence.

Pathways to sexual health communication between adolescent girls and their female caregivers participating in a structured HIV prevention intervention in South Africa

RATIONALE

Interventions that promote sexual health communication between adolescents and their parents or other primary caregivers are an important tool for reducing female adolescents' behavioral risk. Understanding the mechanisms by which interventions effectively foster communication can inform future programs.

OBJECTIVE

An initial evaluation of Let's Talk, a structured, family-centered HIV prevention intervention for vulnerable adolescents in South Africa, found an increase in caregiver-adolescent sexual communication. This analysis expands upon initial findings to explore the role of parental knowledge, the quality of the parent-adolescent relationship, and the mental health of both parties on caregiver-adolescent sexual health communication.

METHOD

Using mixed methods data collected in 2015 and 2016, structural equation modeling of differenced pre- and postintervention survey data from 64 female Let's Talk participants ages 13-17 and their caregivers was used to explore the pathway to increased frequency of caregiver-adolescent sexual health communication. Focus group discussions (FGDs) were held with intervention participants (n = 25) and facilitators (n = 6).

RESULTS

The path analysis indicates that caregivers' mental health indirectly affected caregiver-adolescent relationship quality, and adolescents' mental health exerted a direct effect. Relationship quality, in turn, directly affected the level of parental sexual communication reported by the adolescent. FGDs suggested that cultural norms inhibit frank discussions between caregivers and adolescents about sexual health, but that thoughtfully designed interventions such as Let's Talk can mitigate this barrier. Qualitative findings also echoed quantitative findings about the role of caregiver-adolescent relationship quality and mental health on communication frequency and highlighted the importance of enhancing participants' technical knowledge and particularly their skills related to expression, listening, and anger management to help enable sensitive conversations.

CONCLUSIONS

Findings overall suggest that a holistic intervention approach emphasizing caregiver-adolescent relationship development and designed to support the mental health of both parties may hold significant promise for enhancing sexual health communication.

Factors associated with retention intentions among Isibindi child and youth care workers in South Africa: results from a national survey

BACKGROUND

Child and youth care workers (CYCWs) are a crucial and growing component of South Africa's national response to HIV and AIDS and other issues affecting children and families. CYCWs use the community-centred Isibindi model of care to reach the most vulnerable with key services including psychosocial, health, economic and education support. Like others in similar professions, they may be at risk for occupational challenges affecting retention.

METHODS

This study uses data from the first nationally representative survey of CYCWs in South Africa to identify factors associated with workers' retention intentions. Data were collected in 2015 as part of a formative evaluation conducted around the mid-point of a nationwide Isibindi programme expansion. A total of 1158 CYCWs from 78 sites participated. The response rate for the sample was 87%. Questions addressed demographics, work history, retention intentions, training, mentorship and supervision experiences, workload and remuneration. Mixed effects regression models with random intercepts for project site and mentor were used to estimate factors associated with retention intentions.

RESULTS

High-quality mentorship and frequent supervision support retention intentions among CYCWs. Respondents who indicated that wanting to help children or the community was their primary motivator for seeking work as a CYCW were also more likely to report intending to continue working as a CYCW. High perceived workloads and feeling threatened or unsafe on the job were negatively associated with retention intentions. As CYCWs gained experience, they were also less likely to intend to stay.

CONCLUSIONS

Understanding the factors affecting retention in the CYCW workforce is vital to helping vulnerable children and families across South Africa access key social and health services. Findings highlight the importance of mentoring and supervision as part of the Isibindi model and the value of support for manageable workloads, workplace safety, and career advancement opportunities for promoting worker retention.

Development and formative evaluation of a family-centred adolescent HIV prevention programme in South Africa

Preventing HIV among young people is critical to achieving and sustaining global epidemic control. Evidence from Western settings suggests that family-centred prevention interventions may be associated with greater reductions in risk behaviour than standard adolescent-only models. Despite this, family-centred models for adolescent HIV prevention are nearly non-existent in South Africa - home to more people living with HIV than any other country. This paper describes the development and formative evaluation of one such intervention: an evidence-informed, locally relevant, adolescent prevention intervention engaging caregivers as co-participants. The programme, originally consisting of 19 sessions for caregivers and 14 for adolescents, was piloted with 12 groups of caregiver-adolescent dyads by community-based organizations (CBOs) in KwaZulu-Natal and Gauteng provinces. Literature and expert reviews were employed in the development process, and evaluation methods included analysis of attendance records, session-level fidelity checklists and facilitator feedback forms collected during the programme pilot. Facilitator focus group discussions and an implementer programme workshop were also held. Results highlighted the need to enhance training content related to cognitive behavioural theory and group management techniques, as well as increase the cultural relevance of activities in the curriculum. Participant attendance challenges were also identified, leading to a shortened and simplified session set. Findings overall were used to finalize materials and guidance for a revised 14-week group programme consisting of individual and joint sessions for adolescents and their caregivers, which may be implemented by community-based facilitators in other settings.

Complicated grief and caregiving correlates among bereaved adolescent girls in South Africa

To our knowledge, this is the first study to document correlates of complicated grief among bereaved adolescents in sub-Saharan Africa. Participants included 339 female adolescents in South Africa who experienced the loss of a loved one at least six months prior to the survey; their primary caregivers were also surveyed. One-fifth of adolescents were classified as having complicated grief using the Inventory of Complicated Grief Revised for Children in conjunction with grief-induced functional impairment. The loss of a biological parent, the primary caregiver's level of grief, and economic stressors since the loss were associated with increased odds of complicated grief among adolescents. Adolescents' age, residential changes, time since the loss, multiple losses, bereavement due to death by illness, and caregiver depression did not affect the odds. Findings signal the potential of family-centered interventions and economic support services for bereaved adolescents.

Mitigating depression among orphaned and vulnerable adolescents: a randomized controlled trial of interpersonal psychotherapy for groups in South Africa

BACKGROUND

Children and adolescents affected by HIV are at elevated risk of depression, yet research on related interventions in this population is scarce in sub-Saharan Africa. This study sought to examine the effects of interpersonal psychotherapy for groups (IPTG) on depressive symptomology among orphaned and vulnerable adolescents in South Africa.

METHOD

A cluster randomized controlled trial wherein adolescents ages 14-17 enrolled in community-based programming for HIV-affected and vulnerable families were randomly assigned by geographic cluster to participate in a 16-session IPTG intervention or the standard of care (n = 489). Baseline and postintervention surveys conducted with enrollees included standardized depression screening. Utilizing an intent-to-treat design, mixed effects models were performed to examine treatment effects for all participants and potential moderators including gender and baseline depression level (Clinical Trials registration: ClinicalTrials.gov NCT02386878).

RESULTS

While 23% of adolescents in the intervention group did not attend any IPTG sessions, average attendance was 12 out of 16 possible sessions among participants. The intervention was not associated with changes in depression symptomology.

CONCLUSIONS

Results underscore the importance of mitigating participation barriers prior to intervention roll-out and the need for increased evidence for psychological health interventions to mitigate depression among orphaned and vulnerable adolescents. This intervention and the study selectively targeted at-risk adolescents versus using diagnostic mental health criteria for enrollment; more research is needed to identify the potential benefits and disadvantages of these approaches.

Promoting uptake of child HIV testing: an evaluation of the role of a home visiting program for orphans and vulnerable children in South Africa

HIV counseling and testing (HCT) is critical for children in generalized epidemic settings, but significant shortfalls in coverage persist, notably among orphans and others at disproportionate risk of infection. This study investigates the impact of a home visiting program in South Africa on orphaned and vulnerable children's uptake of HCT. Using propensity score matching, survey data for children receiving home visits from trained community-based care workers were compared to data from children living in similar households that had not yet received home visits (n = 1324). Home visits by community-based care workers increased the odds of a child being tested by 97% (OR = 1.97, 95% CI = 1.34-2.92). The home visitation program had an especially pronounced effect on orphans, more than doubling their odds of being tested (OR = 2.12, 95% CI = 1.00-4.47) compared to orphans living in similar households that did not receive home visits. Orphan status alone had no effect on HCT independent of program exposure, suggesting that the program was uniquely able to increase testing in this subgroup. Results highlight the potential for increasing HCT access among children at high risk through targeted community-based initiatives.

Family Functioning and Child Behavioral Problems in Households Affected by HIV and AIDS in Kenya

HIV places acute stressors on affected children and families; especially in resource limited contexts like sub-Saharan Africa. Despite their importance, the epidemic's potential consequences for family dynamics and children's psychological health are understudied. Using a population-based sample of 2,487 caregivers and 3,423 children aged 8-14 years from the Central Province of Kenya, analyses were conducted to examine whether parental illness and loss were associated with family functioning and children's externalizing behaviors. After controlling for demographics, a significant relationship between parental illness and externalizing behaviors was found among children of both genders. Orphan status was associated with behavioral problems among only girls. Regardless of gender, children experiencing both parental loss and illness fared the worst. Family functioning measured from the perspective of both caregivers and children also had an independent and important relationship with behavioral problems. Findings suggest that psychological and behavioral health needs may be elevated in households coping with serious illness and reiterate the importance of a family-centered approach for HIV-affected children.

Home visiting programs for HIV-affected families: a comparison of service quality between volunteer-driven and paraprofessional models

Home visiting is a popular component of programs for HIV-affected children in sub-Saharan Africa, but its implementation varies widely. While some home visitors are lay volunteers, other programs invest in more highly trained paraprofessional staff. This paper describes a study investigating whether additional investment in paraprofessional staffing translated into higher quality service delivery in one program context. Beneficiary children and caregivers at sites in KwaZulu-Natal, South Africa were interviewed after 2 years of program enrollment and asked to report about their experiences with home visiting. Analysis focused on intervention exposure, including visit intensity, duration and the kinds of emotional, informational and tangible support provided. Few beneficiaries reported receiving home visits in program models primarily driven by lay volunteers; when visits did occur, they were shorter and more infrequent. Paraprofessional-driven programs not only provided significantly more home visits, but also provided greater interaction with the child, communication on a larger variety of topics, and more tangible support to caregivers. These results suggest that programs that invest in compensation and extensive training for home visitors are better able to serve and retain beneficiaries, and they support a move toward establishing a professional workforce of home visitors to support vulnerable children and families in South Africa.

Caregiver burden among adults caring for orphaned children in rural South Africa

The AIDS epidemic has created an unprecedented number of orphans. While largely absorbed by extended family, this additional responsibility can weigh heavily on their caregivers. The concept of caregiver burden captures multiple dimensions of well-being (e.g., physical, social and psychological). Measuring the extent and determinants of caregiving burden can inform the design of programmes to ease the negative consequences of caregiving. This study uses the baseline data from a study assessing interventions for orphans and vulnerable adolescents in the Eastern Cape, South Africa. Orphan caregivers (n = 726) completed an adapted version of the 12-item Zarit Burden Interview. In addition to basic caregiver and household demographics, the survey also collected information on AIDS-related illness and recent deaths. Descriptive data are presented, followed by multivariate Poisson regression models to explore factors associated with caregiver burden. Approximately 40% of caregivers reported high levels of orphan caregiving burden. Feelings of stress and inadequacy concerning their care responsibilities as well as anger towards the child were common. Household food insecurity was the most important predictor of orphan caregiving burden (marginal effect = 7.82; p < 0.001 for those reporting severe hunger); income was also a significant determinant. When other AIDS impacts were added to the model, only the AIDS-related illness of the caregiver was significantly associated with burden (marginal effect = 3.77; p < 0.001). This study suggests that caregivers with economic vulnerability and those struggling with their own AIDS-related illness feel most overburdened. These findings are particularly relevant to service providers who must identify caregivers in need of immediate assistance and allocate limited resources effectively. To alleviate caregiver burden, programmes must foster greater economic security (e.g., by facilitating access to social grants or directly providing cash transfers) and coordinate services with home-based care programmes serving the chronically ill.

Does investment in home visitors lead to better psychological health for HIV-affected families? Results from a quasi-experimental evaluation in South Africa

Children and families affected by HIV are at considerable risk for psychological distress. Community-based home visiting is a common mechanism for providing basic counseling and other services to HIV-affected families. While programs emphasize home visitor training and compensation as means to promote high-quality service delivery, whether these efforts result in measurable gains in beneficiaries' well-being remains largely unanswered. This study employs a longitudinal quasi-experimental design to explore whether these kinds of investments yield concomitant gains in psychological outcomes among beneficiaries. Baseline and follow-up data were collected over a two-year period from children aged 10–17 at the time of program enrollment and their caregivers, with 80% retention. In this sample of 1487 children and 918 caregivers, the psychological health outcomes of those enrolled in programs with home visitors who receive intensive training, organizational support, and regular compensation (termed “paraprofessional”) were compared to those enrolled in programs offering limited home visiting services from lay volunteers. Applying multilevel logistic regression, no measurable improvements were found among paraprofessional enrollees, and three outcomes were significantly worse at follow-up regardless of program model. Children's behavior problems became more prevalent even after adjusting for other factors, increasing from 29% to 35% in girls and from 28% to 43% in boys. Nearly one-quarter of girl and boys reported high levels of depression at follow-up, and this was a significant rise over time for boys. Rates of poor family functioning also significantly worsened over time, rising from 30% to 59%. About one-third of caregivers reported high levels of negative feelings at follow-up, with no improvements observed in the paraprofessional group. Results highlight that children's and caregivers' psychological outcomes may be relatively impervious to change even in paraprofessional home visiting models. Findings underscore the need for programs serving HIV-affected families toadd focused evidence-based psychological interventions to supplement traditional home visiting.

Caring for the caregiver: evaluation of support groups for guardians of orphans and vulnerable children in Kenya

HIV and AIDS have altered the context in which millions of children in sub-Saharan Africa are raised. Many are under the care of a widowed or ill parent, and others are residing with their extended family. Caregivers of orphans and other vulnerable children (OVC) face a variety of stressors that may adversely affect children. This study explores potential benefits of caregivers' membership in support groups on their own psychosocial wellbeing, and on the treatment and psychosocial well-being of OVC aged 8-14 under their care. A post-test study design comparing members and non-members was applied, drawing upon random samples of current and prospective beneficiaries from a rural community in Kenya. With up to two children per caregiver eligible for study inclusion, the sample comprised 766 caregivers and 1028 children. Three-quarters of children had lost at least one parent. Nearly 90% were cared for by a female, often their natural mother or grandmother. Half of the caregivers were widowed and one-fifth had a chronic illness. Over one-third of caregivers were members of support groups, more commonly female caregivers. Regression analyses assessed the effect of support group membership after controlling for household, caregiver and child characteristics. Members reported less social marginalization, better family functioning and more positive feelings towards the children in their care than nonmembers. Children with caregivers in support groups exhibited fewer behavioral problems, higher rates of prosocial behavior and reported lower incidence of abuse from adults in their household. The psychological state of caregivers, however, was not associated with support group membership. Results underscore that quality care of vulnerable children hinges on interventions that address the psychosocial challenges facing their caregivers.

Depressive symptoms in youth heads of household in Rwanda: correlates and implications for intervention

OBJECTIVE

To examine the level of depressive symptoms and their predictors in youth from one region of Rwanda who function as heads of household (ie, those responsible for caring for other children) and care for younger orphans.

DESIGN

Cross-sectional survey

SETTING

Four adjoining districts in Gigonkoro, an impoverished rural province in southwestern Rwanda.

PARTICIPANTS

Trained interviewers met with the eldest member of each household (n = 539) in which a youth 24 years old or younger was caring for 1 child or more.

MAIN EXPOSURE

Serving as a youth head of household.

MAIN OUTCOME MEASURES

Rates and severity of depressive symptoms using the Center for Epidemiologic Studies Depression scale; measures of grief, adult support, social marginalization, and sociodemographic factors using scales developed for this study.

RESULTS

Of the 539 youth heads of household, 77% were subsistence farmers and only 7% had attended school for 6 years or more. Almost half (44%) reported eating only 1 meal a day in the last week, and 80% rated their health as fair or poor. The mean score on the Center for Epidemiologic Studies Depression scale was 24.4, exceeding the most conservative published cutoff score for adolescents. Multivariate analysis revealed that reports of depressive symptoms that exceeded the clinical cutoff were associated with having 3 basic household assets or fewer, such as a mattress and a spare set of clothes (odds ratio [OR], 1.69; 95% confidence interval [CI], 1.06-2.70), eating less than 1 meal per day (OR, 1.68; 95% CI, 1.09-2.60), reporting fair health (OR, 1.32; 95% CI, 0.76-2.29) or poor health (OR, 2.33; 95% CI, 1.17-4.64), endorsing high levels of grief (OR, 2.67; 95% CI, 1.73-4.13), having at least 1 parent die in the genocide as opposed to all other causes of parental death (OR, 1.83; 95% CI, 1.10-3.04), and not having a close friend (OR, 1.91; 95% CI, 1.17-3.12). There was an interaction between marginalization from the community and alcohol use; youth who were highly marginalized and did not drink alcohol were more than 3 times more likely to report symptoms of depression (OR, 3.07; 95% CI, 1.73-5.42). When models were constructed by grouping theoretically related variables into blocks and controlling for other blocks, the emotional status block of variables (grief and marginalization) accounted for the most variance in depressive symptoms.

CONCLUSIONS

Orphaned youth who head households in rural Rwanda face many challenges and report high rates of depressive symptoms. Interventions designed to go beyond improving food security and increasing household assets may be needed to reduce social isolation of youth heads of household. The effect of head-of-household depressive symptoms on other children living in youth-headed households is unknown.

Sexual risk behavior among South African adolescents: is orphan status a factor?

There is concern that orphans may be at particular risk of HIV infection due to earlier age of sexual onset and higher likelihood of sexual exploitation or abuse; however, there is limited empirical evidence examining this phenomenon. Utilizing data from 1,694 Black South African youth aged 14-18, of whom 31% are classified as orphaned, this analysis explores the relationship between orphan status and sexual risk. The analysis found both male and female orphans significantly more likely to have engaged in sex as compared to non-orphans (49% vs. 39%). After adjusting for socio-demographic variables, orphans were nearly one and half times more likely than non-orphans to have had sex. Among sexually active youth, orphans reported younger age of sexual intercourse with 23% of orphans having had sex by age 13 or younger compared to 15% of non-orphans. Programmatic implications of these findings for the care and protection of orphans are discussed.

Psychosocial support and marginalization of youth-headed households in Rwanda

This research aims to characterize the psychosocial aspects of well-being among youth-headed households (YHH) in Gikongoro, Rwanda, through examination of social support and marginalization. Data is presented on perceived availability of support from relatives, an unidentified adult, peers, and other community members and an index of social marginalization. A total of 692 interviews were completed with YHH age 13-24 who are beneficiaries of a basic needs program. Sixteen percent of youth reported there was no one they felt they could go to with a problem. In times of need, only 24% felt relatives would help them, while 57% felt neighbors would offer assistance. Most youth reported significant caring relationships: 73% reported access to trusted adult who offers them advice and guidance, and most indicated close peer relationships. However, many youth also perceived a lack of community support, with 86% feeling rejected by the community and 57% feeling the community would rather hurt them than help them. Social support is a low-cost critical resource for the care of vulnerable youth and an understanding of existing social support networks would enhance the design and implementation of psychosocial and community-based care initiatives.
